Proteolytic activity and physico-chemical characteristics were studied for Norwegian dry-cured ham at four different times of processing: raw hams, post-salted hams (3 months of processing), hams selected in the middle of the production (12 months of processing) and hams at the end of the processing (24 months). Cathepsin H activity decreased until negligible values after 3 months of processing, whereas cathepsins B and B+L were inactive at 12 months. AAP was the most active aminopeptidase whereas RAP and MAP were active just during the first 12 months of processing. Proteolysis index reached a value of 4.56±1.03 % with non-significant differences between 12 and 24 months of ripening. Peptide identification by LC-MS/MS was done and two peptides (GVEEPPKGHKGNKK and QAISNNKDQGSY) showing a linear response with the time of processing were found. Unfreezable water content and glass transition temperature were investigated using differential scanning calorimetry (DSC) technique with non-significant differences in the temperature of glass transition for 12 and 24 months of processing.

This study evaluated the two-year clinical performance of one microhybrid composite and three different types of flowable resin materials in non-carious cervical lesions. A total of 252 noncarious cervical lesions were restored in 37 patients (12 male, 25 female) with Admira Flow, Dyract Flow, Filtek Flow and Filtek Z250, according to manufacturers' instructions. All the restorations were placed by one operator, and two other examiners evaluated the restorations clinically within one week after placement and after 6, 12, 18 and 24 months, using modified USPHS criteria. At the end of 24 months, 172 restorations were evaluated in 26 patients, with a recall rate of 68%. Statistical analysis was completed using the Pearson Chi-square and Fisher-Freeman-Halton tests (p < 0.05). Additionally, survival rates were analyzed with the Kaplan-Meier estimator and the Log-Rank test (p < 0.05). The Log-Rank test indicated statistically significant differences between the survival rates of Dyract Flow/Admira Flow and Dyract Flow/Filtek Z250 (p < 0.05). While there was a statistically significant difference between Dyract Flow and the other materials for color match at 12 and 18 months, no significant difference was observed among all of the materials tested at 24 months. Significant differences were revealed between Filtek Z250 and the other materials for marginal adaptation at 18 and 24 months (p < 0.05). With respect to marginal discoloration, secondary caries, surface texture and anatomic form, no significant differences were found between the resin materials (p > 0.05). It was concluded that different types of resin materials demonstrated acceptable clinical performance in non-carious cervical lesions, except for the retention rates of the Dyract Flow restorations.

The aim of the present study was to evaluate the effects of femtosecond laser-assisted cataract surgery (FLACS) and phacoemulsification on corneal biomechanics using corneal visualization Scheimpflug technology. The medical records of 50 eyes from 50 patients who received phacoemulsification and intraocular lens implantation because of age-related factors between June 2014 and September 2014 were retrospectively analyzed. FLACS was used in 12 eyes (FLACS group), and conventional phacoemulsification in 38 eyes (PHACO group). The evaluation of corneal biomechanical parameters included the first/second applanation time (A-time1/A-time2), the first/second applanation length (A-length1/A-length2), corneal velocity during the first/second applanation moment (Vin/Vout), highest concavity time, highest concavity-radius (HC-radius), peak distance (PD), deformation amplitude (DA), central corneal thickness (CCT), and intraocular pressure (IOP). The differences in A-length1/A-length2, IOP, CCT, PD, and DA were significant in the PHACO group between those before, 1 week after, and 1 month after surgery. No significant differences in corneal biomechanical parameters were found between those at 1 month after surgery and before surgery. There were significant differences in IOP and CCT in the FLACS group between those before, 1 week after, and 1 month after surgery. There were no significant differences in the other corneal biomechanical parameters. No significant differences were found in corneal biomechanical parameters between those 1 month after surgery and before surgery. There were significant differences in A-length1/A-length2, CCT, PD, and DA between the two groups at 1 week after surgery. There were no significant differences in corneal biomechanical parameters between the two groups at 1 month after surgery. In conclusion, the effect of FLACS on corneal biomechanics is smaller than that of phacoemulsification. The corneal biomechanical parameters are restored to preoperative levels with the healing of the incision, and the reduction of swelling of the tissue near the incision.

To investigate the effects of health education based on integrative therapy of Chinese and Western medicine for type 2 diabetes mellitus (T2DM) from the aspects of knowledge, attitude and practice (KAP), health-related quality of life (HRQoL), body mass index (BMI) and glucose control. Patients were individually randomized into intervention group (receiving integrative education, n=120) and control group (receiving usual education, n=120). The primary outcome was the changes in glycosylated hemoglobin A1c (HbA1c) levels after 3, 6, 9 and 12 months from baseline. Hierarchical linear models (HLMs) were used to assess within-group changes in outcomes over time and between-group differences in patterns of change. Secondary outcomes were KAP scores, HRQoL scores and BMI after 6 and 12 months, paired-sample t test was used to assess within-group changes in outcomes in 6 and 12 months, independent-sample t test was used to assess between-group differences in patterns of change. HbA1c decreased statistically from baseline to 3 months, from 3 to 6 months, from 6 to 9 months and from 9 to 12 months in the intervention group (all P<0.01); and decreased significantly from baseline to 3 months, and from 3 to 6 months in the control group P<0.01). There was a significant between-group difference from baseline to 3 months (P=0.044), from 6 to 9 months (P<0.01) and from 9 to 12 months (P<0.01). Significant improvements in the intervention group along with significant between-group differences were found in KAP and HRQoL scores respectively (all P<0.05). The number in the intervention group of normal weight increased from 56 at baseline to 81 (6 months), 94 (12 months), the number in the control group were 63 (baseline), 69 (6 months), 70 (12 months), the χ 2 of hierarchical analysis of BMI were 6.93 (P=0.075), 10.31 (P=0.016), 15.53 (P<0.01), respectively. Health education based on integrative therapy of Chinese and Western medicine is beneficial to the control of T2DM and should be recommended for T2DM.

Background: The aim of this study was to compare the clinical efficacy of coronally advanced flap (CAF) alone and in combination with autologous platelet rich fibrin membrane (PRF) in Miller's class I and II gingival recessions. Materials and Method: Thirty isolated Miller class I or II sites in 26 subjects were randomly divided into test (15 sites- CAF+PRF) and control (15 sites- CAF alone). Parameters probing pocket depth (PPD), Recession depth (RD), Clinical attachment loss (CAL), Keratinised tissue width (KTW) and Gingival tissue thickness (GTH) were evaluated at baseline, 3 months and 6 months postoperatively. Data was subjected to statistical analysis. P< 0.05 was considered statistically significant. Results: Mean percentage root coverage was 91.00±19.98% and 86.60±23.83% for test and control group respectively. Difference between the groups in all parameters at baseline, 3 months and 6 months was non significant. Complete root coverage was obtained in 12 (80%) and 11 (73.3%) subjects in test and control group respectively. The difference was found to be non-significant. Both groups showed significant differences in all parameters at 3 and 6 months respectively except difference in gingival tissue thickness which was non-significant in control group at 3 months. Conclusion: Combination of PRF to CAF procedure did not provide any added advantage in term of recession coverage in Miller class I and II recessions. Long term trials with more sample size are needed to validate these findings. PMID:26097347

2011-01-01

The Cochrane Oral Health Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), Medline Embase, Lilacs, Allied and Complementary Medicine Database (AMED) and CINAHL databases were searched. In addition the reference lists of the included articles were checked and 14 journals hand searched. Randomised controlled clinical trials (RCT) of arthroscopy for treating TMDs were included. There were no restrictions regarding the language or date of publication. Two review authors independently extracted data, and three review authors independently assessed the risk of bias of included trials. The authors of the selected articles were contacted for additional information. Pooling of trials was only attempted if at least two trials of comparable protocols, with the same conditions and similar outcome measurements were available. Statistical analysis was performed in accordance with the Cochrane Collaboration guidelines. Seven RCTs (n = 349) met the inclusion criteria. All the studies were either at high or unclear risk of bias. Pain was evaluated after six months in two studies. No statistically significant differences were found between the arthroscopy versus nonsurgical groups (standardised mean difference (SMD) = 0.004; 95% confidence interval (CI) - 0.46 to 0.55, P = 0.81). Two studies analysed pain 12 months after surgery (arthroscopy and arthrocentesis) in 81 patients. No statistically significant differences were found (mean difference (MD) = 0.10; 95% CI -1.46 to 1.66, P = 0.90). Three studies analysed the same outcome in patients who had been submitted to arthroscopic surgery or to open surgery and a statistically significant difference was found after 12 months (SMD = 0.45; 95% CI 0.01 to 0.89, P = 0.05) in favour of open surgery.The two studies compared the maximum interincisal opening in six different clinical outcomes (interincisal opening over 35 mm; maximum protrusion over 5 mm; click; crepitation; tenderness on palpation in the TMJ and the jaw muscles 12 months after arthroscopy and open surgery). The outcome measures did not present statistically significant differences (odds ratio (OR) = 1.00; 95% CI 0.45 to 2.21, P = 1.00). Two studies compared the maximum interincisal opening after 12 months of postsurgical follow-up. A statistically significant difference in favour of the arthroscopy group was observed (MD = 5.28; 95% CI 3.46 to 7.10, P < 0.0001).The two studies compared the mandibular function after 12 months of follow-up with 40 patients evaluated. The outcome measure was mandibular functionality (MFIQ). This difference was not statistically significant (MD = 1.58; 95% CI -0.78 to 3.94, P = 0.19). Both arthroscopy and nonsurgical treatments reduced pain after six months. When compared with arthroscopy, open surgery was more effective at reducing pain after 12 months. Nevertheless, there were no differences in mandibular functionality or in other outcomes in clinical evaluations. Arthroscopy led to greater improvement in maximum interincisal opening after 12 months than arthrocentesis; however, there was no difference in pain.

In this poster we applied the moving window approach (see Poster I of this collection) to analyze trends of winter and its corresponding months (December, January, February) temperature mean values of maximum (Tmax) and minimum (Tmin) in Spanish mainland to detect the effects of length period and starting year. Monthly series belong to Monthly Temperature dataset of Spanish mainland (MOTEDAS). Database contains in its grid format of 5236 pixels of monthly series (10x10 km). The threshold used in spatial analyses considers 20% of land under significant trend (p<0.05). The most striking results are as follow: • Seasonal trend analyses of Tmax shows that global trend 1951-2010 was positive and significant mostly in central-western areas; from 1970 to 2010 there is less than 20% of land with significant trend. In the case of Tmin no relevant significant period is detected. • Monthly Tmax analyses show that December significant trend changed from positive (>20%) in between 1955-2010 until 1962-2010, to negative from 1976-2010. Meanwhile January does not show relevant period with significant trend; finally Tmax in February shows different periods with positive significant trend (>20% of land) 1951-2010 to 1954-2010 and 1962-2010 to 1968-2010. No significant trend is detected after this data. • Monthly Tmin trend analyses show that except exceptional period, no months present any significant trend. As conclusions, we have detected that for winter and winter-months, Tmax trends are not significant from 1970 across Spanish mainland. In the case of Tmin we conclude that no significant trend have been occurred in any temporal windows analyzed. Results differ from what traditionally has been assumed that the increase of the average annual temperature was due to the increase of trends in the winter season. And these analyses also show that seasonal trend values could hide monthly behavior. So extreme caution should be taken into account when seasonal values are offered.

Anecdotal case reports, amplified by mass media and internet-based opinion groups, have recently indicated vaccinations as possibly responsible for autoimmunity/lymphoproliferation development. Multiply vaccinated Italian military personnel (group 1, operating in Italy, group 2, operating in Lebanon) were followed-up for nine months to monitor possible post-vaccine autoimmunity/lymphoproliferation onset. No serious adverse event was noticed in both groups. Multivariate analysis of intergroup differences only showed a significant association between lymphocyte increase and tetanus/diphtheria vaccine administration. A significant post-vaccine decrease in autoantibody positivity was observed. Autoantibodies were also studied by microarray analysis of self-proteins in subjects exposed to ≥4 concurrent vaccinations, without observing significant difference among baseline and one and nine months post-vaccine. Moreover, HLA-A2 subjects have been analyzed for the possible CD8T-cell response to apoptotic self-epitopes, without observing significant difference between baseline and one month post-vaccine. Multiple vaccinations in young adults are safe and not associated to autoimmunity/lymphoproliferation onset during a nine-month-long follow-up. Copyright © 2017 Elsevier Inc. All rights reserved.

To investigate whether the long-term use (6 months) of an arginine-calcium carbonate-MFP toothpaste would affect calculus formation and/or gingivitis when compared to a calcium carbonate-MFP toothpaste. This was a double-blind clinical study. Eligible adult subjects (120) entered a 2-month pre-test phase of the study. After receiving an evaluation of oral tissue and a dental prophylaxis, the subjects were provided with a regular fluoride toothpaste, a soft-bristled adult toothbrush with instructions to brush their teeth for 1-minute twice daily (morning and evening) for 2 months. The subjects were then examined for baseline calculus using the Volpe-Manhold Calculus Index (VMI) and gingivitis using the Löe-Silness Gingival Index (GI), along with an oral tissue examination. Qualifying subjects were randomized to two treatment groups: (1) Colgate Sensitive Pro-Relief toothpaste containing 8.0% arginine, 1450 ppm MFP and calcium carbonate (Test group), or (2) Colgate Cavity Protection toothpaste containing 1450 ppm MFP and calcium carbonate (Control group). Subjects were stratified by the VMI score and gender. After a dental prophylaxis (VMI=0), the subjects entered a 6-month test phase. Each received the assigned toothpaste and a soft-bristled adult toothbrush for home use with instructions of brushing teeth for 1 minute twice daily (morning and evening). The examinations of VMI, Löe-Silness GI and oral tissues were conducted after 3 and 6 months. Prior to each study visit, subjects refrained from brushing their teeth as well as eating and drinking for 4 hours. 99 subjects complied with the study protocol and completed the 6-month test phase. No within-treatment comparison was performed for the VMI because it was brought down to zero after the prophylaxis at the baseline of the test phase. For the Löe-Silness GI, subjects of the Test group exhibited a significant difference from baseline at the 3- and 6-month examinations. The 3-month Löe-Silness GI of the Control group was significantly different from that of the baseline; however, its 6-month Löe-Silness GI was not statistically significantly different from the baseline values. After 3 and 6 months, there were no significant differences between the Test and Control groups with respect to the mean VMI scores; there were no statistically significant differences between the two groups with respect to the Löe-Silness GI results after 3 and 6 months of product use.

To compare the perioperative morbidity and early follow-up after diode laser vaporisation of the prostate (LVP) and its modification, diode laser under cold irrigation (LUCI) in patients with symptomatic benign prostatic hyperplasia, as the main disadvantages of LVP are the postoperative pain, dysuria and storage urinary symptoms. This was a single-centre prospective randomised control trial in which 100 patients were randomised to receive LVP (50) or LUCI (50) from June 2011 until July 2012. LUCI is similar to LVP except that it is done under normal irrigation with saline at 4 °C instead of saline at room temperature. The primary outcome measures were the International Prostate Symptom Score (IPSS), IPSS-Dysuria, a pain scale (PS), maximum flow rate (Q max), a quality-of-life (QoL) score and the postvoid residual urine volume (PVR) after 1 month, then the IPSS, Q max, QoL, and PVR at 3 and 12 months. Secondary outcomes included intraoperative surgical variables, e.g., the decline in core temperature, bleeding, peri- and postoperative morbidity. The baseline characteristics of both groups were similar. For the primary outcome measures, there was a statistically significant difference between the groups in all variables except Q max after 1 month, in favour of LUCI. The mean (SD) IPSS at 1 month in the LVP group was 8.97 (1.68), statistically significantly different from that after LUCI, of 6.89 (1.5) (P < 0.05). The mean IPSS-Dysuria at 1 month was also significantly, at -2.32 (0.91) for LVP and 3.54 (1.07) for LUCI (P < 0.05). The respective mean PS at 1 month was 7.84 (2.92) and 5.7 (2.1) (P < 0.05). The QoL and PVR at 1 month were also significantly different. Within the first month 17% of patients in the LVP group and 4% in the LUCI group complained of transient urgency or stress incontinence, and this difference was statistically significant (P < 0.05). There was no significant bleeding in either group. The mean operative time or applied energy of LVP was not statistically significant from that of LUCI, and there was no significant difference in the decline in core temperature between the groups (P > 0.05). LUCI is a good modification for reducing the pain, dysuria and storage symptoms associated with LVP. The procedure appears to be safe, with no significant decrease in core temperature in either group.

BACKGROUND Following a thoracolumbar burst fracture (TCBF), anterior screw-rods apply pressure upon the graft site. However, there is limited evidence comparing single screw-rod anterior instrumentation (SSRAI) to double screw-rod anterior instrumentation (DSRAI) for TCBFs. Our objective was to compare SSRAI versus DSRAI for TCBFs with incomplete neurological deficit. MATERIAL AND METHODS A total of 51 participants with T11-L2 TCBFs (AO classification: A3) were randomly assigned to receive SSRAI or DSRAI. Key preoperative, perioperative, and postoperative data were collected. Statistical analysis was conducted to determine the independent factors associated with inferior clinical outcomes, as well as the comparative efficacy of SSRAI and DSRAI. RESULTS There were no significant differences in the key demographic and clinical characteristics between the two groups (all p>0.05). Smoking status was significantly associated with inferior three-month and six-month Denis pain scores (Wald statistic=4.246, p=0.039). Both SSRAI and DSRAI were significantly effective in improving three-month and six-month postoperative degree of kyphosis, three-month and six-month postoperative ASIA impairment scale scores, three-month and six-month postoperative Denis pain score, and three-month and six-month postoperative Denis work score (all p<0.001). Although there were no significant differences between DSRAI and SSRAI with respect to all outcomes (all p>0.05), DSRAI displayed significantly longer operating times, as well as significantly larger operative blood losses (both p<0.001). CONCLUSIONS SSRAI may be preferable over DSRAI for TCBFs with incomplete neurological deficit due to its lower operating time and amount of operative blood loss.

We have examined the effect of oral monthly ibandronate on distal radius and tibia microarchitecture with high-resolution peripheral quantitative tomography compared with placebo, in women with osteopenia, and found that ibandronate did not significantly affect trabecular bone but improved cortical density and thickness at the tibia. We have examined the effect of ibandronate on bone microarchitecture with peripheral high-resolution quantitative computed tomography (HR-pQCT) in a randomized placebo-controlled trial among 148 women with osteopenia. Patients received either oral 150 mg monthly ibandronate or placebo over 24 months. Bone microarchitecture was assessed at baseline, 6, 12, and 24 months, using HR-pQCT at the distal radius and tibia; areal bone mineral density (aBMD) was measured with DXA at the spine, hip, and radius. At 12 months, there was no significant difference in trabecular bone volume at the radius (the primary end point) between women on ibandronate (10.8 ± 2.5%) and placebo (10.5 ± 2.9%), p = 0.25. There was no significant difference in other radius trabecular and cortical microarchitecture parameters at 12 and 24 months. In contrast, at the tibia, cortical vBMD in the ibandronate group was significantly greater than in the placebo group at 6, 12, and 24 months, with better cortical thickness at 6, 12, and 24 months. With ibandronate, aBMD was significantly increased at the hip and spine at 12 and 24 months but at the radius was significantly superior to placebo only at 24 months. Most of the adverse events related to ibandronate were expected with bisphosphonate use, and none of them were serious. We conclude that 12 months of treatment with ibandronate in women with osteopenia did not affect trabecular bone microarchitecture, but improved cortical vBMD at the tibia at 12 and 24 months, and preserved cortical thickness at the tibia.

To investigate the effect(s) of intravitreally injected ranibizumab on retinal vessel diameter in patients with diabetic macular edema. Participants of this prospective study were 14 men and 16 women (30 eyes) aged 60 ± 11 years (mean ± standard deviation), all with clinically significant diabetic macular edema. Treatment comprised 3 intravitreal injections of ranibizumab given at 4-week intervals. Examinations were conducted before the first (baseline), before the second (Month 1), before the third (Month 2) injections, and 3 months after baseline (Month 3). Measured parameters included systemic blood pressure, static retinal vessel analysis (central retinal artery equivalent and central retinal vein equivalent), and dynamic retinal vessel analysis, as measured by the change in vessel diameter in response to flicker stimulation during three measurement cycles. Flicker stimulation was accomplished using a 50-second baseline recording, followed by an online measurement during 20-second flicker stimulation and 80-second online measurements in both arteriolar and venular vessel segments. Static retinal vessel analysis showed a reduction of central retinal artery equivalent from 186.25 ± 51.40 μm (baseline) to 173.20 ± 22.2 μm (Month 1), to 174.30 ± 27.30 μm (Month 2), and to 170.56 ± 22.89 μm (Month 3), none of which was statistically significant (P = 0.23, 0.12, and 0.14, respectively). Central retinal vein equivalent was reduced from 216.21 ± 25.0 μm (baseline) to 214.48 ± 25.4 μm (Month 1), to 214.80 ± 24.30 μm (Month 2), and to 211.41 ± 24.30 μm (Month 3), revealing no statistically significant differences between examination time points (P = 0.54, 0.06, and 0.24, respectively). Dynamic vessel analysis yielded a mean retinal arterial diameter change of +1.47% ± 2.3 (baseline), +1.91% ± 2.5 (Month 1), +1.76% ± 2.2 (Month 2), and +1.66% ± 2.1 (Month 3), none of which showed statistically significant differences (P = 0.32, 0.49, and 0.70, respectively). Mean retinal venous diameter changes were +3.15% ± 1.7 (baseline), +3.7% ± 2.3 (Month 1), +4.0% ± 2.0 (Month 2), and +4.95% ± 1.9 (Month 3), none of which showed statistically significant differences (P = 0.12, 0.17, and 0.14, respectively). Central retinal thickness, as measured by spectral domain optical coherence tomography, decreased significantly from 435.2 ± 131.8 μm (baseline) to 372.3 ± 142.8 μm (Month 3), P = 0.01. Regression analysis of arteriolar and venular diameters indicated that there was no significant correlation between these 2 parameters (r = 0.053; P = 0.835 and r = 0.06; P = 0.817, respectively). Also, no significant correlation was observed between the difference in the central retinal thickness and change in arteriolar or venular dilatation (r = 0.291, P = 0.241 and r = 0.06, P = 0.435, respectively). Intravitreally applied ranibizumab did not significantly affect retinal vessel diameter in patients with diabetic macular edema. Decline in the central foveal thickness after ranibizumab therapy, as measured by spectral domain optical coherence tomography, was not linked to any change in retinal vessel diameter or dilatatory response, neither for arterioles nor venules.

To evaluate the psychosexual benefit obtained from multicomponent penile implant surgery in patients with erectile dysfunction. A psychosexual questionnaire was given to 35 patients undergoing penile prosthesis implantation before surgery and at 3 months, 6 months, and 1 year after surgery. The questionnaire consisted of 13 questions scored on a scale from 1 through 5. Results of the questionnaire were statistically analyzed for differences among the preoperative, 3-month postoperative, 6-month postoperative, and 1-year postoperative period. The general linear model evaluation showed a significant difference for each overall combination of the following pairs: preoperative versus 3 months postoperative (P=0.0005) and 3 months postoperative versus 6 months postoperative (P=0.002). There was no overall difference between psychosexual total score at 6 months after surgery and 1 year after prosthesis implantation (P=0.85). The patients perceived improvement in their erectile ability and libido. Concern about obtaining and maintaining an erection during intercourse was significantly alleviated. There was an increase in the frequency of sexual activity and an improvement in satisfaction with sex life. A decrease in feelings of sadness, depression, anxiety, anger, frustration, and embarrassment related to sexual activity was also noted. The current study demonstrates significant improvement in the psychosexual well being of multicomponent penile implant recipients, with attainment of a high level of patient satisfaction up to 1 year after surgery.

This study aimed to examine the nutritional effect of breast feeding on healthy term infants by using urinary metabolome analysis. Urine samples were collected from 19 and 14 infants at 1 and 6 months, respectively. Infants were separated into two groups: the breast-fed group receiving <540 mL/week of their intake from formula (n=13 at 1 month; n=9 at 6 months); and the formula-fed group receiving no breast milk (BM) (n=6 at 1 month; n=5 at 6 months). Urinary metabolome analysis was performed using capillary electrophoresis-time-of-flight mass spectrometry (CE-TOF/MS). A total of 29 metabolites were detected by CE-TOF/MS metabolome analysis in all samples. Urinary excretion of choline metabolites (choline base solution, N,N-dimethylglycine, sarcosine, and betaine) at 1 month were significantly (p<0.05) higher in breast-fed infants than in formula-fed infants. However, choline metabolites were not significantly different between the groups at 6 months. Urinary excretion of lactic acid in breast-fed infants at 1 and 6 months was significantly lower than that in formula-fed infants. Urinary l(-)-threonine and l-carnosine excretion at 1 month was significantly lower in breast-fed infants than in formula-fed infants, but it was not significantly different between the groups at 6 months. The type of feeding in early infancy affects choline metabolism, as well as lactate, threonine, and carnosine levels, in healthy term infants. Urinary metabolome analysis by the CE-TOF/MS method is useful for assessing nutritional metabolism in infants.

Our primary aim was to determine the short-term effects of a ketogenic diet on cardiac ventricular function in patients with refractory epilepsy. Thirty-eight drug-resistant epileptic patients who were treated with a ketogenic diet were enrolled in this prospective study. Echocardiography was performed on all patients before beginning the ketogenic diet and after the sixth month of therapy. Two-dimensional, M-mode, color flow, spectral Doppler, and pulsed-wave tissue Doppler imaging measurements were performed on all patients. The median age of the 32 patients was 45.5 months, and 22 (57.8%) of them were male. Body weight, height, and body mass index increased significantly at the sixth month of therapy when compared with baseline values (P < 0.05). Baseline variables assessed by conventional M-mode echocardiography showed no significant difference at month 6 (P > 0.05). Doppler flow indices of mitral annulus and tricuspid annulus velocity of patients at baseline and month 6 showed no significant differences (P > 0.05). Tricuspid annular E/A ratio was lower at month 6 (P < 0.05). Although mitral annulus tissue Doppler imaging studies showed no significant difference (P > 0.05), there was a decrease in Ea velocity and Ea/Aa ratio gathered from tricuspid annulus at month 6 compared with baseline (P < 0.05). A 6-month duration ketogenic diet does not impair left ventricular functions in children with refractory epilepsy; however, it may be associated with a right ventricular diastolic dysfunction.

Objectives To evaluate repeated subgingival air-polishing in residual pockets with a new erythritol powder containing 0.3% chlorhexidine. Material and Methods Single-centre, examiner masked, randomized clinical trial of 12 months with a two-arm, within-subject parallel design. Fifty patients in periodontal maintenance were monitored in 3-month intervals. At months 0, 3, 6 and 9, all sites presenting with a probing depth (PD) >4 mm were subject to subgingival air-polishing (test side) or ultrasonic debridement (control side). The primary endpoint was presence/absence of PD >4 mm after 12 months. Results Totally 6918 sites were monitored at baseline, 457 of them had a PD >4 mm (range 5–9 mm). The number of pockets >4 mm per subject, PD and bleeding on probing were significantly lower at month 12. Differences between test and control were not significant. There was a significant difference in favour of air-polishing for the perception of pain/discomfort. Differences of frequencies at >1000 and >100,000 cells/ml of six microorganisms between baseline and month 12 were not significant. At month 12, test sites were less frequently positive for Aggregatibacter actinomycetemcomitans at >1000 cells/ml than controls, and counts never exceeded 100,000 cells/ml. Conclusions Repeated subgingival air-polishing reduced the number of pockets >4 mm similar to ultrasonic debridement. It was safe and induced less pain. PMID:25041441

To explore whether poor initial insight during a first episode of mania with psychotic features was predictive of poor psychosocial and clinical outcomes at 18 months. Secondary analysis was performed on data collected during an 8-week RCT comparing the efficacy of olanzapine versus chlorpromazine as an adjunct to lithium, and at 18-month follow-up. 74 participants were divided into three groups (no insight, partial insight, and full insight) according to the insight item from the Young Mania Rating Scale (YMRS). Differences between these three groups were examined at baseline and at 18 months on measures of symptoms (YMRS, HAMD-21, and CGI-S), and social and occupational functioning (SOFAS). Baseline differences between the three groups were determined using general linear models and chi-squared analyses. Group differences from baseline to 18-month follow-up were determined using repeated measures general linear models. At baseline there were significant differences between the three insight groups in terms of mania and functioning, but at 18 months all groups had improved significantly in terms of psychopathology, mania, depression and social and occupational functioning. There were no significant differences between the three groups at study completion with respect to these domains. The study was limited by the lack of availability of a more detailed rating scale for insight, and it did not account for the duration of untreated psychosis (DUI). Poor initial insight during a first episode of mania with psychotic features does not predict poor clinical and psychosocial outcome at 18 months. Crown Copyright © 2014. Published by Elsevier B.V.

We compared the results of radiofrequency thermal lesioning (RTL) and extracorporeal shockwave therapy (ESWT) in patients with chronic plantar fasciitis. This prospective study included 56 patients diagnosed with plantar fasciitis who had complaints for ≥6 months: 40 (group 1) underwent ESWT and 16 (group 2) underwent RTL. The presence of calcaneal spurs was investigated with imaging studies. All patients were followed up clinically at baseline and 1, 3, and 6 months after treatment. Clinical evaluations were performed by the visual analog scale (VAS) and the modified Roles-Maudsley (RM) scoring system. There was no significant difference in the age, sex, body mass index, and side of involvement between the groups (all P > .05). Radiographic evaluation showed calcaneal spurs in 22 patients (55%) in group 1 and 7 patients (43%) in group 2. There was no significant difference in the baseline and posttreatment values between the groups; however, group 2 had significantly different RM values at 1 month than group 1 ( P < .05). In both groups, the VAS scores significantly decreased at 1, 3, and 6 months after treatment ( P < .05). The RM scores at 1, 3, and 6 months after treatment significantly decreased in both groups, except for the RM values at 1 month after treatment in group 1 ( P < .05). Our study results suggest that RTL and ESWT are safe and effective treatments in patients with chronic plantar fasciitis. Level II: Therapeutic study.

Rosmarinus officinalis L. is a medicinal plant with diverse activities including enhancement microcapillary perfusion. The present study aimed to investigate the clinical efficacy of rosemary oil in the treatment of androgenetic alopecia (AGA) and compare its effects with minoxidil 2%. Patients with AGA were randomly assigned to rosemary oil (n = 50) or minoxidil 2% (n = 50) for a period of 6 months. After a baseline visit, patients returned to the clinic for efficacy and safety evaluations every 3 months. A standardized professional microphotographic assessment of each volunteer was taken at the initial interview and after 3 and 6 months of the trial. No significant change was observed in the mean hair count at the 3-month endpoint, neither in the rosemary nor in the minoxidil group (P > .05). In contrast, both groups experienced a significant increase in hair count at the 6-month endpoint compared with the baseline and 3-month endpoint (P < .05). No significant difference was found between the study groups regarding hair count either at month 3 or month 6 (> .05). The frequencies of dry hair, greasy hair, and dandruff were not found to be significantly different from baseline at either month 3 or month 6 trial in the groups (P > .05). The frequency of scalp itching at the 3- and 6-month trial points was significantly higher compared with baseline in both groups (P < .05). Scalp itching, however, was more frequent in the minoxidil group at both assessed endpoints (P < .05). The findings of the present trial provided evidence with respect to the efficacy of rosemary oil in the treatment of AGA.

To evaluate the outcome of accelerated and conventional corneal cross-linking (CXL) procedures regarding their effect on morphological and optical properties of the cornea. One hundred fifty-three eyes of 153 patients were evaluated before and during a 15-month follow-up period after CXL (76 eyes in the conventional group and 77 eyes in the accelerated group). Measured variables include corrected distance visual acuity (CDVA), uncorrected distance visual acuity (UDVA), refraction, maximum keratometry, endothelial cell density, anterior and posterior stromal keratocyte density, and subbasal nerve density. All variables were compared between the two study groups. Cylindrical and spherical components of refraction improved significantly during 15 months of follow-up. No difference was observed between the two study groups. UDVA and CDVA improved in the same manner, with no intergroup differences. Endothelial cell density did not change significantly during the follow-up period in either group. K-max increased slightly in the first month of the follow-up, but started to decrease at postoperative visits without any significant difference in the two groups. Anterior stromal keratocyte density and subbasal nerve density decreased significantly in both groups 1 month postoperatively. Both variables had a more significant decrease in the conventional group at all visits before the 1-year visit. At the final 15-month visit, there were no significant differences in any value between the two groups. Accelerated and conventional CXL seem to have a comparable and acceptable effect on keratoconus in the short-term follow-up period. Copyright 2014, SLACK Incorporated.

Objective To investigate the expressions of serum soluble human leukocyte antigen G (sHLA-G) and soluble CD30 (sCD30) in renal transplant recipients at different time after transplantation, and explore the relationship between the expressions of serum sHLA-G, sCD30 and the time after renal transplantation. Methods Eleven kidney transplant recipients and 10 healthy donors were selected, in which the dynamic changes of serum sHLA-G and sCD30 were detected by ELISA before transplantation and 1 year after transplantation; 33 kidney transplant recipients with normal renal graft were selected and divided into three groups: 1-5 years, 5-10 years and 10 years post-transplantation. The expressions of serum sHLA-G and sCD30 in the recipients were tested over one year after transplantation. Results The level of serum sHLA-G before transplantation was not significantly different from that of the control group. There was no significant difference between pre-transplantation, 1 week and 1 month after transplantation. Serum sHLA-G level of renal transplant recipients at 3 months after transplantation was higher than that 1 month after transplantation. There was no significant change in serum sHLA-G level among 3, 6 and 12 months after transplantation. The level of serum sHLA-G in the group of transplant time >10 years was significantly higher than that in the group of transplant time ≤5 years. The serum sHLA-G level was significantly associated with the time after renal transplantation. The level of serum sCD30 before transplantation was higher than that in the control group and decreased in 1 week after transplantation. There were no significant differences in sCD30 level between 1, 3, 6, and 12 months after transplantation, and similarly, there were also no significant differences between the groups of transplant time ≤5 years, 5-10 years and 10 years after transplantation. The level of sCD30 was significantly associated with the time within 1 month after renal transplantation. Conclusion The serum sHLA-G in kidney transplant recipients with normal renal graft increased with the time after renal transplantation, while the serum sCD30 level was reduced within 1 month after renal transplantation.

Although multiple materials have been suggested for pulpotomized primary molars, there is no reliable evidence of the superiority of one particular type. To compare the effectiveness of formocresol (FC), mineral trioxide aggregate (MTA), ferric sulphate, and sodium hypochlorite (NaOCl) as pulp dressing agents in primary molars after 2 years. One hundred primary molars requiring pulp treatment were allocated randomly to the control (FC) and experimental groups (MTA, ferric sulphate, and NaOCl). Clinical and radiographic evaluations were performed at 6, 12, 18, and 24 months. Statistical analysis using Fischer's exact test was performed to determine the significant differences between groups. In the FC and MTA groups, 100% of the available teeth were clinically successful at all follow-up appointments. In the NaOCl group, one clinical failure was found at 18 months, and two clinical failures in the ferric sulphate group were noted at 12 and 24 months, but no significant differences were found among the groups (P = 0.41). No significant differences in radiographic success were found among all the groups at 24 months of follow-up (P = 0.303). No statistically significant differences among the four materials were found at 24 months suggesting that NaOCl may be an appropriate substitute for FC. © 2012 John Wiley & Sons Ltd, BSPD and IAPD.

To evaluate short term quality of life of patients with chronic rhinosinusitis by using Chinese version of the sinonasal outcome test-22 (SNOT-22) and to formulate an ideal therapy system for patients with chronic rhinosinusitis. Using prospective randomized controlled design,we chose the SNOT-22 to evaluate and compare 78 CRS patients' quality of life (QOL) before surgery, at 1-month,3-month, 6-month and 9-month after functional endoscopic sinus surgery(FESS). At the same time, we randomly chose 100 healthy controls to compare their QOL with those of CRS patients after FESS. We found that except for 5 items (cough, ear expanding, otalgia, facail pain and weary ), the grade of 17 other items of CRS patients were significantly higher than those of the healthy controls (P<0. 05). There was no significant difference in 7 items (olfactory sensation, hypogeusis, backflow of nasal discharge, difficult to fall asleep, bad sleep, bad work efficiency, depression, embarrassment ) at 3 months after FESS between chronic rhinosinusitis patients and healthy controls (P>0. 05). There was no significant difference in 9 items (blow noses, sneeze, rhinorrhea, nasal discharge thickness, dizziness, night wake, tired of wake, attention deficit, sense of loss) at 6 months after FESS between chronic rhinosinusitis patients and healthy controls (P>0. 05). There was no significant difference in nasal obstruction at 6 months after FESS between chronic rhinosinusitis patients and healthy controls (P>0.05), at this time the totle grade was normal (P>0. 05). The recovery period of QOL in patients was about 9 months (P>0. 05). The 5 great items were nasal obstruction, olfactory sensation, hypogeusis, nasal discharge, nasal discharge thickness and blow noses. There was no difference in items except for bad sleep replacing nasal discharge thickness between 1-month and 9-month after surgery. The Chinese vesion of SNOT-22 could evaluate QOL of CRS patients in this area. The recovery of QOL of CRS patients needs about 6 months after FESS, but problems of olfactory sensation, hypogeusis, nasal discharge and difficult to sleeep still needs to be resolved.

We aimed to compare the effectiveness of bilateral and unilateral block application in chronic migraine patients and whether there were differences in their effectiveness retrospectively. In chronic migraine patients undergoing Greater occipital nerve (GON) block, mean number of days with pain per month before and after block, mean duration of pain in attacks (in hours), and mean Visual Analog Scale (VAS) in attack and pain severity were recorded from files. The patients underwent one block a week for the first 1 month, thereafter one block a month according to GON block protocol used by our institute. Of 41 patients included in the study, 23 underwent unilateral block (group 1) and 18 underwent bilateral block (group 2). In both groups, number of days with migraine decreased significantly in 2 and 3 months as compared to pre-block treatment (P < 0.001). Mean duration of headache decreased in group 2 during treatment (P < 0.001). In group 1, mean duration of headache also decreased but did not differ significantly (P = 0.051). Mean severity of migraine decreased significantly differ in group 1 in 2, 3 months as compared to pre-block treatment (P < 0.001). No differences were observed in frequency, severity and duration of headache between groups during 3-month treatment period. GON block is effective in chronic migraine and bilateral application is no superior over unilateral application.

To evaluate the osteoconductivity and the bonding strength of the newly developed interbody cage covered with the porous titanium sheet (porous Ti cage) to vertebral bodies in a sheep model. Twelve sheep underwent anterior lumbar interbody fusion at L2-3 and L4-5 using either the new porous Ti cages (Group-P) or conventional Ti cages with autogenous iliac bone (Group-C). The animals were euthanized at 2 or 4 months postoperatively and subjected to radiological, biomechanical, and histological examinations. Computed tomography analyses showed that the ratio of bone contact area in Group-P was significantly increased at 4 months compared with that at 2 months (p = 0.01). Although the ratio of bone contact area in Group-C was significantly higher than Group-P at 2 months (p < 0.001), there was no statistically significant difference between the two groups at 4 months. Biomechanical test showed that there was no significant difference in bonding strength between the two groups at either 2 or 4 months. Histological analyses revealed that the bone apposition ratio increased significantly with time in Group-P (p < 0.001). Although Group-C showed significantly higher bone apposition ratio than Group-P at 2 months (p = 0.001), there was no statistical difference between the two groups at 4 months. There was bone ingrowth into the porous Ti sheet, and bonding capacity of the porous Ti cage to the host bone increased with time. However, the speed of union to the bone with a porous Ti cage was marginally lower than a conventional cage along with an autogenous bone graft. Although it needs further experiment with a larger sample size, the results of the current study suggested that this material could achieve interbody fusion without the need for bone grafts.

The aim of this study was to investigate the effects of whole-body vibration training with different frequencies on the balance and flexibility of the healthy elderly. The participants were recruited from hospital volunteers and the community; all of them were healthy subjects, all over 65 years of age. The study involved three randomized groups in a parallel and single-blind design. The main outcome variables included the limits of stability test and the sit and reach test, which were measured at pre-training, Month 1 (Mid-training), Month 3 (Post-training), and Month 6 (Follow-up). A total of 45 subjects, with a mean age of 69.6 ± 3.9 years, were randomly divided into three groups. There was significant interaction in the performance of the limits of stability and sit and reach tests in the different groups at the four different time points (F = 25.218, P < 0.001, F = 12.235, P < 0.001, respectively). There was a significant difference in balance performance between the vibration groups at the frequencies of 20 Hz and 40 Hz and the control group at Month 1, Month 3, and Month 6 (P < 0.001). Whole-body vibration training at 20 Hz has significant benefit to the balance and flexibility of the elderly who do not engage in habitual exercise.

Objective: To explore the change of optical zone after femtosecond laser assisted laser in sitn keratomileusis(FS-LASIK) so as to provide the reference for measurement and design of clinical optical zone. Methods: This retrospective case series study covers 41 eyes of 24 patients (7 males and 17 females, aged from 18 to 42 years old) with myopia and myopic astigmatism who have received FS-LASIK surgery at Corneal Refractive Department of Qingdao Eye Hospital and completed over 6 months of clinical follow-up. Pentacam system (with the application of 6 corneal topographic map modes including: the pure axial curvature topographic map, the pure tangential curvature topographic map, the axial curvature difference topographic map, the tangential curvature difference topographic map, the postoperative front elevation map and the corneal thickness difference topographic map), combined with transparent concentric software (a system independently developed by Qingdao Eye Hospital) was used to measure the optical zone at 1, 3 and 6 months postoperatively, the optical zone diameters measurement results among different follow-up times in group were analyzed with the repeated measures analysis of variance, and the actual measured values and the theoretical design values of the optical zone were analyzed with independent-samples t-testing. Spearman correlation coefficient ( r(s) ) have been applied to evaluate the relationship between postoperative optical zone measurement values and the potential influencing factors. Results: The optical zone diameters measured by pure axial curvature topographic map at 1, 3 and 6 months after FS-LASIK showed (6.55±0.50)mm, (6.50±0.53)mm and (6.48±0.53)mm respectively. The differences between values are of no statistical significance ( F= 1.60, P= 0.21), the optical zone diameter measured by pure tangential curvature topographic map at 1, 3 and 6 months after FS-LASIK showed (5.44±0.46)mm, (5.46±0.52)mm and (5.44±0.50)mm respectively, the differences between values are of no statistical significance ( F= 0.17, P= 0.85). The optical zone diameters measured by postoperative front elevation map at 1, 3 and 6 months after FS-LASIK showed (5.06±0.28)mm, (5.12±0.32)mm and (5.17±0.28)mm respectively. The differences between the values of 3 and 6 months postoperatively are of no statistical significance ( F= 6.14, P= 0.15), the optical zone diameters measured by axial curvature difference topographic map at 1, 3 and 6 months after FS-LASIK showed (6.51±0.37)mm, (6.45±0.41)mm and (6.41±0.40)mm respectively, and the differences between the values of 3 and 6 months postoperatively are of no statistical significance ( F= 7.25, P= 0.05). The optical zone diameters measured by tangential curvature difference topographic map at 1, 3 and 6 months after FS-LASIK showed (5.21±0.23)mm, (5.16±0.19)mm and (5.17±0.20) mm respectively, and the differences between the values of 1 and 3 months postoperatively are of statistical significance ( F= 1.75, P= 0.04). The optical zone diameters measured by corneal thickness difference topographic map at 1, 3 and 6 months after FS-LASIK showed (6.53±0.40)mm, (6.39±0.43)mm and (6.41±0.47)mm respectively, and the differences between the values of 1 and 3 months postoperatively are of statistical significance ( F= 1.67, P= 0.032). The actual measured optical zone values from the 6 different modes of Pentacam system are less than the theoretical design values (7.75 mm), and the differences were statistical significance ( t= -15.42, -29.39, -59.27, -21.47, -81.69, -18.22, P< 0.01). Conclusions: The optical zone measurement values tend to be stable at 3 months after FS-LASIK. The actual measured values from all the 6 different modes of Pentacam system were less than the theoretical design values. The results from pure tangential curvature topographic map, the tangential curvature difference topographic map and the postoperative front elevation map showed greater variation with clear border, which was beneficial for eccentric research. The results from pure axial curvature topographic map, the axial curvature difference topographic map and the corneal thickness difference topographic map were close to the theoretically designed values. Furthermore, the axial curvature difference topographic map showed clearer border and less variation thus maybe more favorable for measuring optical zone in clinical application.

The aim of the present study was to assess bone volume changes in maxillary molar regions after delayed implants placement. Patients presented large bone defects after tooth extractions. Reactive soft tissue was left into the defects. No grafts were used. Cone beam computed tomography (CBCT) scans were performed before tooth extractions, at implant placement (at 3 months from extraction) and 3 years after implant placement, bone volume measurements were assessed. Bucco-lingual width showed a statistically significant decrease (p = .013) at implant placement, 3 months after extraction. Moreover, a statistically significant increase (p < .01) was measured 3 years after implant placement. No statistically significant differences (p > .05) were found between baseline values (before extraction) and at 3 years from implant placement. Vertical dimension showed no statistically significant differences (p > .05) at implant placement, 3 months after extraction. Statistically significant differences (p < .0001) were found between baseline values (before extraction) and at 3 months from implant placement as well as between implant placement values and 3 years later. CT scans presented successful outcome of delayed implants placed in large bone defects at 3-year follow-up. © 2016 Wiley Periodicals, Inc.

Gender differences in psychotropic use across Europe: Results from a large cross-sectional, population-based study.

In many epidemiological studies, women have been observed to consume psychotropic medication more often than men. However, the consistency of this relationship across Europe, with differences in mental health care (MHC) resources and reimbursement policies, is unknown. Questions on 12-month psychotropic use (antidepressants, benzodiazepines, antipsychotics, mood stabilizers) were asked to 34,204 respondents from 10 European countries of the EU-World Mental Health surveys. Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) criteria were used to determine 12-month prevalence of mood/anxiety disorders using the Composite International Diagnostic Interview (v3.0). For all participating countries, women were significantly more likely than men to use psychotropic medication within the previous 12 months (overall-OR=2.04, 95% CI: 1.81-2.31). This relationship remained significant after adjusting for common sociodemographic factors (age, income level, employment status, education, marital status) and country-level indicators (MHC provision, private household out-of-pocket expenditure, and Gender Gap Index). In multivariable gender-stratified risk-factor analysis, both women and men were more likely to have taken psychotropic medication with increasing age, decreasing income level, and mental health care use within the past 12 months, with no significant differences between genders. When only including participants with a mental disorder, gender differences overall were still significant with any 12-month mood disorder but not with any 12-month anxiety disorder, remaining so after adjusting for sociodemographic characteristics and country-level indicators. Women use psychotropic medication consistently more often than men, yet reasons for their use are similar between genders. These differences also appear to be contingent on the specific mental disorder. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

The purpose of this study was to assess vital bone formation at 4 to 5 months and 7 to 9 months following sinus augmentation with anorganic bovine bone matrix (ABBM) with and without recombinant human platelet-derived growth factor (rhPDGF). Twenty-four subjects received bilateral sinus elevation surgery with ABBM on one side and ABBM and rhPDGF on the contralateral side. Twelve patients had core sampling at 4 to 5 months and 12 patients at 7 to 9 months postoperatively. In subjects with cores taken at 4 to 5 months, mean vital bone, connective tissue, and residual graft were 11.8%, 54.1%, and 33.6%, respectively, with ABBM alone. Cores of sinuses filled with ABBM and rhPDGF showed mean 21.1% vital bone, 51.4% connective tissue, and 24.8% residual graft. Paired t test showed a statistically significant difference in vital bone. In cores taken at 7 to 9 months, the values for ABBM alone and ABBM + rhPDGF were 21.4% vs 19.5% vital bone, 28.4% vs 44.2% connective tissue, and 40.3% residual graft vs 35.5%. There was no statistically significant difference in vital bone at 7 to 9 months after surgery. Test and control groups showed clinically acceptable levels of vital bone both at 4 to 5 months and 7 to 9 months postsurgery. However, vital bone formation was significantly greater in the 4- to 5-month sections of ABBM + rhPDGF vs the Bio-Oss alone. In the 7- to 9-month specimens, this difference disappeared. More rapid formation of vital bone with the addition of rhPDGF may allow for earlier implant placement.

To experimentally intervene safe injection by medical staff in basic-level hospitals and observe the recent and long-term effect after the intervention and to provide practical measures to improve safe injection. We used random sampling methods to set up groups in county hospitals and township hospitals of Hunan Province, and offered lectures, delivered safe injection guide, brochure and on-site guidance in the experimental group. We surveyed the 2 groups after the intervention at 1 month and 6 months to compare the effect of unsafe injection behaviors and safe injection behaviors. One month after the intervention, the unsafe injection rate in the experimental group decreased from 27.8% to 21.7%, while in the control group injection the unsafe injection rate rose from 26.0% to 27.9%, with significant difference (P<0.01). Six months after the intervention, the unsafe injection rate in the experimental group declined to 18.4% while the unsafe injection rate in the control group also dropped to 22.4%, with significant difference (P<0.01). Unsafe injection rate was decreased in the experimental group at different intervention points, with significant difference (P<0.01). The safe injection behavior scores in the experimental group were higher than those in the control group after the intervention of 1 month and 6 month intervention (P<0.01); the experimental group got higher scores after the intervention (P<0.01). Training of safe injection, distribution of safe injection guide, and comprehensive intervention model can significantly change the primary care practitioners' behaviors in unsafe injections and it is worth promoting.

To examine in a randomised trial whether a 25% difference in mortality exists between 4.5 months and 3 years of age for children given two standard doses of Edmonston-Zagreb measles vaccines at 4.5 and 9 months of age compared with those given one dose of measles vaccine at 9 months of age (current policy). Randomised controlled trial. The Bandim Health Project, Guinea-Bissau, which maintains a health and demographic surveillance system in an urban area. 6648 children aged 4.5 months of age who had received three doses of diphtheria-tetanus-pertussis vaccine at least four weeks before enrolment. A large proportion of the children (80%) had previously taken part in randomised trials of neonatal vitamin A supplementation. Children were randomised to receive Edmonston-Zagreb measles vaccine at 4.5 and 9 months of age (group A), no vaccine at 4.5 months and Edmonston-Zagreb measles vaccine at 9 months of age (group B), or no vaccine at 4.5 months and Schwarz measles vaccine at 9 months of age (group C). Main outcome measure Mortality rate ratio between 4.5 and 36 months of age for group A compared with groups B and C. Secondary outcomes tested the hypothesis that the beneficial effect was stronger in the 4.5 to 9 months age group, in girls, and in the dry season, but the study was not powered to test whether effects differed significantly between subgroups. In the intention to treat analysis of mortality between 4.5 and 36 months of age the mortality rate ratio of children who received two doses of Edmonston-Zagreb vaccine at 4.5 and 9 months of age compared with those who received a single dose of Edmonston-Zagreb vaccine or Schwarz vaccine at 9 months of age was 0.78 (95% confidence interval 0.59 to 1.05). In the analyses of secondary outcomes, the intention to treat mortality rate ratio was 0.67 (0.38 to 1.19) between 4.5 and 9 months and 0.83 (0.83 to 1.16) between 9 and 36 months of age. The effect on mortality between 4.5 and 36 months of age was significant for girls (intention to treat mortality rate ratio 0.64 (0.42 to 0.98)), although this was not significantly different from the effect in boys (0.95 (0.64 to 1.42)) (interaction test, P=0.18). The effect did not differ between the dry season and the rainy season. As neonatal vitamin A supplementation is not WHO policy, the analyses were done separately for the 3402 children who did not receive neonatal vitamin A. In these children, the two dose Edmonston-Zagreb measles vaccine schedule was associated with a significantly lower mortality between 4.5 and 36 months of age (intention to treat mortality rate ratio 0.59 (0.39 to 0.89)). The effect was again significant for girls but not statistically significant from the effect in boys. When measles cases were censored, the intention to treat mortality rate ratio was 0.65 (0.43 to 0.99). Although the overall effect did not reach statistical significance, the results may indicate that a two dose schedule with Edmonston-Zagreb measles vaccine given at 4.5 and 9 months of age has beneficial non-specific effects on children's survival, particularly for girls and for children who have not received neonatal vitamin A. This should be tested in future studies in different locations. Clinical trials NCT00168558.

To evaluate the effectiveness of the combination of vitrectomy with kallidinogenase for diabetic macular edema (DME). This study was designed as a prospective, randomized, multicenter study comparing 19 eyes of 19 patients who received 150 units of kallidinogenase administered a day for 52 weeks from the day after vitrectomy (study group) with 20 eyes of 20 patients who received no kallidinogenase (control group). The main outcome measurements included logMAR visual acuity and central foveal thickness (CFT) before surgery and at 3, 6, 9, and 12 months after vitrectomy. During follow-up, 11 patients dropped out (six in the study group and five in the control group), leaving 28 eyes in 28 patients for analysis (13 in the study group and 15 in the control group). Visual acuity improved significantly at 12 months in both groups compared with before surgery. The degree of improvement did not differ significantly between the groups. At 12 months, the mean CFT decreased significantly in both groups, with no significant difference in the rate of change between the two groups. In the study group, the visual acuity and CFT significantly improved from 3 to 12 months and from 6 to 12 months, whereas these parameters did not continue to improve in the control group after 6 months (for visual acuity) or 3 months (for CFT). After vitrectomy for DME, visual acuity and CFT improved significantly in both groups, but only patients treated with kallidinogenase continued to have significant improvement throughout the study period.

The aim of this study was threefold: (1) Assess the pressure loss of two types of pressure garments that are used in the treatment of hypertrophic scars after burn injury, (2) investigate the influence of two different levels of compression on erythema and thickness of burn scars and (3) examine the association between erythema and thickness. The study was a prospective trial in which 76 burn scars in 60 patients were objectively assessed with the Minolta Chromameter CR-300 for erythema and with the Dermascan C for thickness of the scar over a period of 3 months. Each patient was randomly assigned to a "normal" or "lower" compression class treatment, with respectively mean values of 15 and 10 mmHg pressure after wearing the garment for 1 month. Measurements for both parameters were taken at 0, 1, 2 and 3 months of treatment. Pressure garments with "normal" compression did lose significantly more compression over 1 month (4.82 mmHg) than did the garments from the low compression class (2.57 mmHg). Scars that were treated with garments from a "normal" compression class did score significantly better for thickness compared to the "low" compression class. The difference in thickness was most evident at 1 month. Thereafter no further significant improvement between the two different treatments over time could be obtained. This difference was not found for erythema. Positive correlations could be found between erythema and thickness values at all of the three test points while changes in erythema and thickness only correlated significantly after the first month. The pattern of change of both parameters correlated at a high level of significance after 3 months of treatment. These data suggest that pressure garments that deliver a pressure of at least 15 mmHg pressure tend to accelerate scar maturation and that measurements of the pattern of change of the erythema can be used to predict changes in scar thickness and vice versa.

To evaluate the influence of patellar replacement on total knee arthroplasty by comparing with non patellar replacement. Between September 2010 and November 2010, 63 patients (63 knees) with osteoarthritis who met the selection criteria and underwent total knee arthroplasty, were randomly divided into 2 groups: patellar replacement in 32 cases (replacement group), non patellar replacement in 31 cases (non patellar replacement group). There was no significant difference in gender, age, disease duration, osteoarthritis grading, the clinical and functional scores of American Knee Society Score (KSS), the patellar tilt angle, tibiofemoral angle, and patellar ligament ratio between 2 groups (P > 0.05), they were comparable. After 6 weeks, 3, 6, and 12 months of operation, clinical and imaging evaluation methods were used to assessment the effectiveness. Primary healing of incision was obtained in all patients of 2 groups. Deep venous thrombosis occurred in 6 cases of replacement group and in 8 cases of non patellar replacement group. All patients were followed up 12 months. The postoperative incidence of anterior knee pain in replacement group was significantly lower than that in non patellar replacement group (P < 0.05) at 3, 6, and 12 months after operation. No significant difference was found in the postoperative KSS clinical score between 2 groups at each time point (P > 0.05). The joint function score of the replacement group was significantly higher than that of the non patellar replacement group at the other time point (P < 0.05) except the score at 6 weeks and 3 months. Significant difference was found in the patella score between 2 groups at 12 months (P < 0.05), but no significant difference at the other time points (P > 0.05). X-ray film showed no patellar fracture and dislocation, or loosening and breakage of internal fixation. At 12 months after operation, the tibiofemoral angle, the patellar ligament ratio, and the patellar tilt angle showed no significant difference between 2 groups (P > 0.05). Patella replacement can improve knee function score and the patella score, and reduce the incidence of postoperative anterior knee pain.

This study aimed to compare the inactivation rate and the mechanisms of pathogenic bacteria in three matrixes (sawdust, rice husk and charcoal) during the composting process. The inactivation rate was evaluated with Escherichia coli strain and the damaged parts and/or functions were evaluated with three different media. Normalized inactivation rate constant in three media and from three matrixes had no significant difference in each process (pure, 1 month and 2 months). The value in rice husk was relatively increased during 2 months but there was no significant difference. The inactivation rate constants of Tryptic Soy Agar (TSA) and Compact Dry E. coli/Coliform in pure sawdust and rice husk were relatively lower than that of Desoxycholate Agar, but increased in 2 months. This indicated that damaging part was changed from outer membrane to enzymes and metabolisms during the 2-month composting process. In the case of charcoal, only the TSA value in apure matrix was relatively lower than that of others, but it increased in 2 months. This indicated that damaging part was changed from outer membrane and enzyme to metabolisms during the composting process. Composting matrix and composting process did not significantly affect inactivation rate of pathogenic bacteria during the process but affected the damaging part of the bacteria.

Background and aims: Maximum phonation time (MPT), which is related to respiratory function, is widely used to evaluate maximum vocal capabilities, because its use is non-invasive, quick, and inexpensive. We aimed to examine differences in MPT by age, following recovery phase II cardiac rehabilitation (CR). Methods: This longitudinal observational study assessed 50 consecutive cardiac patients who were divided into the middle-aged group (<65 years, n = 29) and older-aged group (≥65 years, n = 21). MPTs were measured at 1 and 3 months after cardiac surgery, and were compared. Results: The duration of MPT increased more significantly from month 1 to month 3 in the middle-aged group (19.2 ± 7.8 to 27.1 ± 11.6 s, p < 0.001) than in the older-aged group (12.6 ± 3.5 to 17.9 ± 6.0 s, p < 0.001). However, no statistically significant difference occurred in the % change of MPT from 1 month to 3 months after cardiac surgery between the middle-aged group and older-aged group, respectively (41.1% vs. 42.1%). In addition, there were no significant interactions of MPT in the two groups for 1 versus 3 months (F = 1.65, p = 0.20). Conclusion: Following phase II, CR improved MPT for all cardiac surgery patients. PMID:29267218

Various sociocultural factors affect healthcare-seeking behaviors. In Taiwanese society, superstitions and lunar festivals play important roles in people’s lives. We investigated the impact of “Ghost Month” (the 7th lunar month) and Chinese New Year (the 12th lunar month and the 1st lunar month of the following year) on the number of elective surgeries and emergent surgeries in Taiwan. The number of total knee replacement (TKR) surgeries and proximal femur fracture (PFF) surgeries in each lunar month from 2000 to 2011 were extracted from the Taiwan National Health Insurance Database, a computerized and population-based database. Patients were then sorted by location of residence or gender. The average number of TKR surgeries performed was significantly lower during the 1st, 7th, and 12th lunar months in urban areas, whereas in rural areas this trend was only evident in the 7th and 12th lunar months. There was however, no significant difference in the average number of PFF surgeries in each lunar month except for an increase seen in the 1st lunar month in rural patients (p<0.05). When sorted by gender, the average number of TKR surgeries was significantly decreased in the 7th and 12th lunar months in male patients, and decreased in the 1st, 7th, and 12th lunar months in female patients. In contrast, there was no difference in the average numbers of PFF surgeries in the 7th and 12th lunar months either in male or female patients. We proposed that the timing of elective surgeries such as TKR might be influenced by Ghost Month and Chinese New Year; however, emergent PFF surgeries were not significantly influenced by sociocultural beliefs and taboos in Taiwan.

Many techniques and graft materials have been used for the reconstruction of the tympanic membrane. We conducted a retrospective study to compare anatomic and functional outcomes of type 1 tympanoplasty that we performed with boomerang-shaped chondroperichondrial cartilage grafts (BSGs) and shield-shaped chondroperichondrial cartilage grafts (SSGs) in pediatric patients. Our study population was made up 121 patients-61 boys and 60 girls, aged 7 to 16 years (mean: 12.4)-who had undergone a type 1 tympanoplasty. Patients were divided into two groups according to the grafting technique used; there were 59 patients in the BSG group and 62 patients in the SSG group. Ear examinations were performed at postoperative months 3, 6, 12, and 24, and pure-tone average (PTA) for air-conduction threshold values and air-bone gaps (ABGs) were evaluated at 0.5, 1.0, 2.0, and 4.0 kHz at the same visits. We also investigated the impact of the graft material on functional graft success and intergroup differences (if any) in surgical success. Mean postoperative follow-up periods were 30.5 and 30.2 months in the BSG and SSG groups, respectively. We found that the success rates for tympanic membrane reconstruction were not significantly different in the two groups (91.5 and 88.7%). Postoperatively, the mean PTA and ABG values in both groups at 3, 6, 12, and 24 months were significantly lower than the preoperative values (p < 0.05). There were no significant differences in mean PTA values between the two groups at 3, 6, 12, and 24 months. However, the extent of the decrease in PTA values in the BSG group at 3 months was significantly greater than that of the SSG group (p < 0.05). There were no significant differences in mean ABG values between the two groups at 3, 6, and 12 months, but at 24 months, the value was significantly higher in the BSG group (p < 0.05). Finally, the extent of the decrease in ABG in the BSG group at both 3 and 6 months was significantly greater than that of the SSG group (p < 0.05). We conclude that the BSG procedure is a reliable and safe method of performing pediatric tympanoplasty.

Head and neck cancer treatment affects quality of life. There are differences in quality of life outcomes and perceived supportive care needs between cancer patients living in metropolitan and regional-remote areas. This study investigated quality of life over the first 6 months following head and neck cancer diagnosis and observed differences in quality of life by geographical location. Prospective observational study. Tertiary hospital in Brisbane, Australia. Newly diagnosed patients who were referred for the diagnosis, and/or treatment of head and neck cancer. Quality of life was measured by the University of Washington Quality of Life Survey, version 4 (UW-QoL). Participants completed the UW-QoL questionnaire prior to starting treatment, 1 month and 6 months post treatment. Metropolitan and regional or remote status was classified according to the Australian Standard Geographic Classification-Remoteness Area system. Ninety-five participants were included at baseline; 49 and 41 participants completed the 1-month and 6-month follow-ups, respectively. Scores in most UW-QoL domains decreased between baseline and 1 month post treatment and increased towards pre-treatment scores at the 6-month follow-up (except for anxiety and saliva). Pain at baseline was significantly worse in the regional-remote participants compared with metropolitan participants. No other statistically significant differences in UW-QoL score by geographical location were observed. The findings generally did not support significant differences in quality of life outcome between metropolitan and regional-remote head and neck cancer patients. The difference in pain experience between metropolitan and regional-remote groups requires further investigation. © 2018 National Rural Health Alliance Ltd.

Follow-up treatment effects of contingency management and motivational interviewing on substance use: A meta-analysis.

Motivation is an integral factor in substance use treatment and long-term recovery. However, it is unclear what role intrinsic and extrinsic motivation play across different treatment modalities. A meta-analysis (N = 84) was performed to estimate the pooled effect size of Motivational Interviewing (MI; primarily targeting intrinsic motivation) and contingency management (CM; primarily targeting extrinsic motivation) at different follow-up periods. Collapsed across all substance types, CM had a significant effect at 3-month follow-up, only. In contrast, MI had a significant effect at 6-month follow-up, only. CM had small and medium effects on multiple substances at 3-month follow-up (i.e., tobacco, marijuana, stimulants, polysubstances), but not at 6-month follow-up. MI had 1 significant medium effect at 3-month follow-up (i.e., marijuana), but several significant small effects at 6-month follow-up (i.e., alcohol, tobacco, polysubstances). This meta-analysis suggests that both CM and MI promote reductions in a range of substances, even several months after the intervention concludes. Further, these results provide some evidence that extrinsically focused CM may produce medium follow-up effects in the short run, but intrinsically focused MI may produce small but durable follow-up effects. However, this interpretation is complicated by the differences between the MI and CM studies that preclude statistical tests comparing effect sizes, and few studies assessed motivation itself. Future researchers should investigate how motivational dynamics impact lasting outcomes in substance use treatment. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

To compare the effects of ultrasound-guided platelet-rich plasma (PRP) and whole blood (WB) injections in patients with chronic hamstring tendinopathy. In a prospective double-blind randomized controlled trial, PRP or WB was injected under ultrasound guidance into the proximal hamstring tendon in a cohort of patients with clinically suspected hamstring tendinosis. Questionnaires were administered before injection and 2, 6, and 12 weeks and 6 months after injection. Pain and function outcomes were measured via the Modified Harris Hip Score (MHHS), Hip Outcome Scores for activities of daily living (ADL) and sport-specific function, and International Hip Outcome Tool 33 (IHOT-33). Diagnostic ultrasound was used to compare preinjection and 6-month postinjection tendon appearances. The WB group showed greater improvements in pain and function over the PRP group before 12 weeks, whereas the PRP group showed improved outcomes over WB at 6 months. None of these between-group outcome measures, except 6-week IHOT-33, showed statistical significance. Comparing preinjection and 6-month scores, the PRP group showed significant improvements in ADL (P = .018) and IHOT-33 (P = .28) scores, whereas the WB group showed no significant improvements from baseline. The WB group showed significantly decreased pain with 15-minute sitting (P= .008) at 6 months. Ultrasound imaging showed no significant differences between PRP and WB group tendon appearances. Both PRP and WB groups showed improvements in all outcome measures at 6 months. The PRP group showed significant improvements in 6-month ADL and IHOT-33 scores. The WB group reached significance in 15-minute sitting pain. No significant between-group differences were observed at any time point. © 2015 by the American Institute of Ultrasound in Medicine.

Aim: To study the effectiveness of the addition of citicoline to patching in the treatment of amblyopia in the age group of 4-13 years. Materials and Methods: A randomized controlled trial, which included patients who were randomly divided into two groups. Both the groups received patching therapy till plateau was achieved in phase 1 of the study. Then in phase 2, group I received citicoline plus patching and group II continued to receive only patching. Outcome Measures: Outcome was measured by the visual acuity in logMAR every month in phase 1 till plateau was achieved and then for 12 months in phase 2. Results: No significant difference was found in the mean visual acuities in these two groups in phase 1 till plateau was reached. In phase 2, for the initial four months, there was no significant difference in the visual acuities in these two groups, at the respective intervals. However, five months onward, up to 12 months, there was a significant difference in the visual acuities in these groups. The result was the same in younger patients (< seven years of age) as well as in older patients (> seven years of age). In phase 2, the mean proportional improvement in group I was significantly more than that in group II, at two months and onward, at the respective intervals. Conclusion: The improvement in visual acuity with citicoline plus patching was significantly more than that with patching alone, in one year of treatment. PMID:24618483

Evidence links depression and stress to more rapid progression of HIV-1 disease. We conducted a randomized controlled trial to test whether an intervention aimed at improving stress management and emotion regulation, mindfulness-based stress reduction (MBSR), would improve immunological (i.e. CD4+ t-cell counts) and psychological outcomes in persons with HIV-1 infection. We randomly assigned participants with HIV-1 infection and CD4 T-cell counts > 350 cells/μl who were not on antiretroviral therapy in a 1:1 ratio to either an MBSR group (n=89) or an HIV disease self-management skills group (n=88). The study was conducted at the University of California at San Francisco. We assessed immunologic (CD4, c-reactive protein, IL-6, and d-dimer) and psychological measures (Beck Depression Inventory for depression, modified Differential Emotions Scale for positive and negative affect, Perceived stress-scale, and mindfulness) at 3, 6 and 12 months after initiation of the intervention; we used multiple imputation to address missing values. We observed statistically significant improvements from baseline to 3-months within the MBSR group in depression, positive and negative affect, perceived stress, and mindfulness; between group differences in change were significantly greater in the MBSR group only for positive affect (per item difference on DES-positive 0.25, 95% CI 0.049, 0.44, p = .015). By 12 months the between group difference in positive affect was not statistically significant, although both groups had trends toward improvements compared to baseline in several psychological outcomes that were maintained at 12-months; these improvements were only statistically significant for depression and negative affect in the MBSR group and perceived stress for the control group. The groups did not differ significantly on rates of antiretroviral therapy initiation (MBSR = 39%, control = 29%, p = .22). After 12 months, the mean decrease in CD4+ T-cell count was 49.6 cells/μl in participants in the MBSR arm, compared to 54.2 cells/μl in the control group, a difference of 4.6 cells favoring the MBSR group (95% CI, -44.6, 53.7, p=.85). The between group differences in other immunologic-related outcomes (c-reactive protein, IL-6, HIV-1 viral load, and d-dimer) were not statistically significant at any time point. MBSR improved positive affect more than an active control arm in the 3 months following the start of the intervention. However, this difference was not maintained over the 12-month follow-up and there were no significant differences in immunologic outcomes between intervention groups. These results emphasize the need for further carefully designed research if we are to translate evidence linking psychological states to immunological outcomes into evidence-based clinical practices.

To explore the feature of primary light chain amyloidosis patients treated with high-dose melphalan with auto peripheral blood stem cell transplantation (auto-PBSCT) and bortezomib plus dexamethasone (VD). Thirty-eight patients diagnosed from September 2004 to September 2012 were analyzed retrospectively, including 15 cases received auto-PBSCT, 23 cases exposed with VD. The median follow-up duration for the patients was 34 months (range, 1-112 months), including auto-PBSCT group of 38 months (range, 5-112 months) and VD group of 31 months (range, 1-108 months). The organ response rate in all the patients was 39.5% (15/38), and the organ response rate between these two groups has no significant difference [33.3% (5/15) vs 43.5% (10/23), P=0.532]. However, the median time of organ response was significant difference [6 (3-10) months vs 3 (1-6) months, respectively (P=0.032)]. The 3-year overall survival (OS) rates in the two groups were 72.0% and 66.9%, and their average survival were 84.7 months and 75.9 months, respectively (P=0.683). In the patients with auto-PBSCT, the occurrence of III-IV grade of bone marrow suppression (P<0.001), fever (P<0.001), nausea and infection (P=0.006) were obviously higher than those with VD, but there was no statistically significant difference in pulmonary infection (P=0.069) and bloodstream infection (P=0.059). The preliminary results have presented that primary light chain amyloidosis patients treated with auto-PBSCT or VD had similar organ response rate and survival. However, more adverse events occurred in the group of auto-PBSCT.

Background: To compare changes in the amount and distribution of dental plaque associated with placement of elastomeric modules over a self-ligating bracket during orthodontic treatment and to relate these changes to the periodontal inflammation. Materials and Methods: A cross-arch randomization trial was carried out at Bristol Dental School, United Kingdom. Clinical measurements of periodontal inflammation and plaque accumulation and microbiological test were done on 24 patients aged 11-14 years [Mean (SD) age = 12.6 (1.01) years] wearing fixed appliances (Damon 2 brackets, Ormco, Orange, CA, USA) at the start and 3 months into fixed orthodontic treatment. Results: In the first 3 months of treatment there was no statistically significant difference in bleeding on probing between incisors with and without elastomeric modules (P = 0.125 and 0.508, respectively). The difference in plaque accumulation was not statistically significant (P = 0.78). The difference in probing depths between the incisors was not statistically significant (P = 0.84). The microbiological analysis showed no difference. Conclusions: Based on this preliminary 3 months study, elastomeric modules were not significantly associated with any increased risk during treatment when compared to self-ligating brackets. The longer term studies are needed to further confirm the findings of the present study. PMID:24987657

The purpose of this study is to analyze the development of musicality in children after cochlear implantation, and provide a clinical database for the evaluation of their musicality. Twenty-six children with cochlear implants (CI group) participated in this research. They received cochlear implants at the age of 11 to 68 months with a mean of 35.6 months. Seventy-six infants as a control group aged from 1 to 24 months with a mean of 6.1 months participated in this study, whose hearing were considered normal by passing the case history collection, high-risk registers for hearing loss and hearing screening using DPOAE. The music and young children with CIs: Musicality Rating Scale was used to evaluate their musicality. The evaluation was performed before cochlear implantation and 1, 3, 6, 9, 12, 24 months after cochlear implantation for children with cochlear implants. The evaluation was also performed at 1, 3, 6, 9, 12, 24 months for children with normal hearing. The mean scores of musicality showed significant improvements with time of CI use for CI group (P<0.05). The mean scores of musicality also showed significant improvements with time for control group (P<0.05). There were no significant differences in mean scores between CI group and control group at 1, 3, 6, 9, 12 months of hearing age by rank sum test (P>0.05). Significant difference was noted between the two groups at 24 months (P<0.05). The musicality of children with cochlear implants improved significantly with time after cochlear implantation. The most rapid growth was found in the first year after cochlear implantation.

The aim of this study was to investigate the long term efficacy of family-focused cognitive behaviour therapy (CBT) compared with psycho-education in improving school attendance and other secondary outcomes in adolescents with chronic fatigue syndrome (CFS). A 24 month follow-up of a randomised controlled trial was carried out. Participants received either 13 one-hour sessions of family-focused CBT or four one-hour sessions of psycho-education. Forty-four participants took part in the follow-up study. The proportion of participants reporting at least 70% school attendance (the primary outcome) at 24 months was 90% in CBT group and 84% in psycho-education group; the difference between the groups was not statistically significant (OR = 1.29, p = 0.80). The proportion of adolescents who had recovered in the family-focused CBT group was 79% compared with 64% in the psycho-education, according to a definition including fatigue and school attendance. This difference was not statistically significant (Fisher's exact test, p = 0.34). Family-focused CBT was associated with significantly better emotional and behavioural adjustment at 24 month follow-up compared to psycho-education, as reported by both adolescents (F = 6.49, p = 0.02) and parents (F = 4.52, P = 0.04). Impairment significantly decreased in both groups between six and 24 month follow-ups, with no significant group difference in improvement over this period. Gains previously observed for other secondary outcomes at six month follow-up were maintained at 24 month follow-up with no further significant improvement or group differences in improvement. In conclusion, gains achieved by adolescents with CFS who had undertaken family-focused CBT and psycho-education generally continued or were maintained at two-year follow-up. The exception was that family-focused CBT was associated with maintained improvements in emotional and behavioural difficulties whereas psycho-education was associated with deterioration in these outcomes between six and 24-month follow-up.

A cross-sectional study of 469 adult (>18 years) Bengalee male slum dwellers of Dum Dum, Kolkata, India, was undertaken to study the relationships of family income and house type with body mass index (BMI) and chronic energy deficiency. The overall frequency of chronic energy deficiency was 32.0%. Based on the World Health Organization classification, the prevalence of chronic energy deficiency among this population was high and thus the situation is serious. Overall, monthly family income was significantly positively correlated with BMI. Significant differences in mean weight, BMI and monthly family income, were observed between the two house type groups. All values were found to be significantly higher in the brick household group who also earned a comparatively higher income as evident from the mean monthly family income values. The prevalence of chronic energy deficiency was also found to be significantly higher in the bamboo-fenced household group. Subjects belonging to the lowest family income group had the lowest mean BMI and the highest rate of chronic energy deficiency while those in the highest family income group had the largest mean BMI and lowest rate of chronic energy deficiency. There was a significant family income group difference in mean BMI. There existed significant differences in chronic energy deficiency rates in family income group categories. Linear regression analyses showed that monthly family income and house type had a significant impact on BMI. Subsequent multiple regression analyses revealed that both monthly family income and house type had a significant impact on BMI, even after controlling for each other.

Intractable plantar fasciitis can be a difficult condition to treat. Early results of platelet rich plasma (PRP) injection have been promising. We compared PRP to traditional cortisone injection in the treatment of chronic cases of plantar fasciitis resistant to traditional nonoperative management. The aim of the study was to compare the efficacy of PRP to that of Steroid at 3, 6 and 12 months after injection. 60 heels with intractable plantar fasciitis who had failed conservative treatment were randomised to receive either PRP or Steroid injection. All patients were assessed with the Roles-Maudsley (RM) Score, Visual Analogue Score (VAS) for pain and the American Orthopaedic Foot and Ankle Society (AOFAS) score. Data was collected prospectively on the cohort, pre-treatment, at 3, 6 and 12 months post injection and the results were compared. Pre-injection, the two groups were well matched with no statistically significant difference. At 3 months, all three outcome scores had significantly improved from their pretreatment level in both groups. The scores in the Steroid arm were marginally better than in the PRP arm, but this difference was not statistically significant. At 6 months, there was no statistically significant difference between the two groups, though there was a trend for the PRP scores to become better than the Steroid scores. At 12 months, the RM, VAS and AOFAS scores in the PRP arm (1.9, 3.3 and 88.5) were significantly better than the Steroid arm (2.6, 5.3 and 75) with P values of .013, .028 and .033, respectively. PRP is as effective as Steroid injection at achieving symptom relief at 3 and 6 months after injection, for the treatment of plantar fasciitis, but unlike Steroid, its effect does not wear off with time. At 12 months, PRP is significantly more effective than Steroid, making it better and more durable than cortisone injection. Copyright © 2015 Elsevier Ltd. All rights reserved.

A comparison of different treatment modalities of peri-implantitis can lead to the development and application of more effective and efficient methods of therapy in clinical practice. This study compares the effectiveness of open flap debridement used alone, with an approach employing the additional use of a diode laser for the treatment of peri-implantitis. Nineteen patients were divided into two groups and treated for peri-implantitis. In the control group (C group), the therapy utilized access flaps, plastic curettes, and sterilized gauzes soaked in saline. The test group (L group) was treated similarly but with additional irradiation using a diode laser. The parameters studied were pocket depth (PD) as the primary outcome variable, clinical attachment level (CAL), bleeding on probing (BOP), and plaque index (PI) as secondary variables. Measurements were performed at three different time points, baseline (BSL), 3 months, and 6 months after treatment. Three months after treatment, a mean PD reduction of 1.19 mm for the control group and 1.38 mm for the laser group was recorded. The corresponding BOP changes were 72.9 and 66.7%, respectively. These changes were significant and remained at the same levels at the 6-month examination (p < 0.05). CAL was reduced significantly only in group L from 5.25 mm at baseline to 4.54 mm at 3 months, remaining at this level at 6 months (p < 0.05). PI was reduced significantly in group C at 3 months from 37.5 to 6.3%. The 6-month data showed no statistically significant difference (p < 0.05) from the 3-month measurements. The two methods of therapy for peri-implantitis examined seemed to be equally efficient in the reduction of the PD and BOP 3 months after surgery, with the results sustained at the same levels after 6 months. CAL significantly improved only in the test group after 3 months. PI was reduced and maintained at low levels in both groups. Surgical treatment of peri-implantitis by access flaps leads to improvement of all clinical parameters studied while the additional use of diode laser does not seem to have an extra beneficiary effect. The additional use of a diode laser in the surgical treatment of peri-implantitis offers a limited clinical benefit.

The objective of this study is to compare the efficacy of mature mud pack and hot pack therapies on patients with knee osteoarthritis. This study was designed as a prospective, randomized-controlled, and single-blinded clinical trial. Twenty-seven patients with clinical and radiologic evidence of knee osteoarthritis were randomly assigned into two groups and were treated with mature mud packs (n 15) or hot packs (n=12). Patients were evaluated for pain [based on the visual analog scale (VAS)], function (WOMAC, 6 min walking distance), quality of life [Short Form-36 (SF-36)], and serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and insulin-like growth factor-1 (IGF-1) at baseline, post-treatment, and 3 and 6~months after treatment. The mud pack group shows a significant improvement in VAS, pain, stifness, and physical function domains of WOMAC. The difference between groups of pain and physical activity domains is significant at post-treatment in favor of mud pack. For a 6 min walking distance, mud pack shows significant improvement, and the difference is significant between groups in favor of mud pack at post-treatment and 3 and 6 months after treatment. Mud pack shows significant improvement in the pain subscale of SF-36 at the third month continuing until the sixth month after the treatment. Significant improvements are found for the social function, vitality/energy, physical role disability, and general health subscales of SF-36 in favor of the mud pack compared with the hot pack group at post-treatment. A significant increase is detected for IGF-1 in the mud pack group 3 months after treatment compared with the baseline, and the difference is significant between groups 3 months after the treatment. Mud pack is a favorable option compared with hotpack for pain relief and for the improvement of functional conditions in treating patients with knee osteoarthritis.

Following the introduction of modified cellulosic and then synthetic membrane dialyzers, it was realized that the dialyzer bio-incompatibility depends on the membrane composition. We designed a prospective, randomized, cohort study of 6 months to determine several parameters of biocompatibility in maintenance hemodialysis (MHD) patients treated with four different membrane dialyzers. There were 60 MHD patients enrolled in the study. In baseline, synthetic low-flux dialyzer, polysulfone (PS) membrane was used in all patients for at least 3 months. Then the patients were randomly divided into three groups according to different dialyzer membranes. Synthetic high-flux dialyzer group, polyethersulfone membrane, cellulose triacetate (CTA) high-flux membrane, and synthetic low-flux dialyzer, polymethylmethacrylate (PMMA) membrane were used in 6 months. A new dialyzer was used for each study treatment, and there was no dialyzer reuse. The biocompatibility markers and solutes removal markers were detected repeatedly at different time points. The blood levels of highly sensitive C reactive protein, interleukin (IL)-1β, and interleukin (IL)-13 showed no difference among different groups at al time points. However, the blood complement levels and white blood cell counts were significantly different among three groups. When the dialyzers changed from PS to PMMA membrane, C3a levels and white blood cell counts changed significantly (p < 0.05). Moreover, the changes of C5a levels were significantly different between group CTA and group PMMA in month 3 (p < 0.05). There were much more differences on bio-incompatibility among different dialyzer membranes.

To evaluate the effectiveness of microplate fixation in open-door cervical expansive laminoplasty (ELP) by comparing with anchor fixation. Between January 2005 and October 2008, 35 patients with multi-segment cervical spondylotic myelopathy were treated. Of them, 15 patients underwent ELP by microplate fixation (microplate group) and 20 patients underwent ELP by anchor fixation (anchor group). In microplate group, there were 10 males and 5 females with the age of (51.2 +/- 11.5) years; the disease duration ranged from 6 to 60 months (mean, 14 months); and the preoperative Japanese Orthopaedic Association (JOA) score was 7.7 +/- 2.5. In anchor group, there were 13 males and 7 females with the age of (50.7 +/- 10.8) years; the disease duration ranged from 3 to 58 months (mean, 17 months); and the preoperative JOA score was 7.8 +/- 2.9. There was no significant difference in the general data, such as gender, age, and JOA score between 2 groups (P > 0.05). All incisions healed by first intention. Thirty-five cases were followed up 24-68 months (mean, 32 months). The operation time was (113 +/- 24) minutes in anchor group and (111 +/- 27) minutes in microplate group, showing no significant difference (t = 0.231 3, P = 0.818 5). The rate of spinal canal expansion in microplate group (60% +/- 24%) was significantly higher than that in anchor group (40% +/- 18%) (t = 2.820, P = 0.008). The JOA scores of 2 groups at 3 months and 24 months after operation were significantly higher than the preoperative scores (P < 0.01). There was no significant difference in JOA score between 2 groups at 3 months after operation (t = 1.620 5, P = 0.114 6), but the JOA score of microplate group was significantly higher than that of anchor group at 24 months after operation (t = 3.454 3, P = 0.001 5). X-ray film, MRI, and CT scan at 3-6 months after operation displayed that door spindle reached bony fusion. There was no occurrence of "re-close of door" in 2 groups. The rate of complication in microplate group (13.3%, 2/15) was significantly lower than that in anchor group (25.0%, 5/20) (chi2 = 7.160 0, P = 0.008 6). ELP by microplate fixation can achieve the stability quickly after operation, which can help patients to do functional exercises early, and has satisfactory effectiveness and less complications.

Many patients still have high blood pressure (BP) after treatment with angiotensin II type 1 (AT 1 ) receptor blockers (ARBs). We compared the efficacy and safety of azilsartan to those of olmesartan in a prospective randomized clinical trial. Sixty-four hypertensive patients who were treated with ARBs other than azilsartan and olmesartan were enrolled in this study. We randomly assigned patients to changeover from their prior ARBs to either azilsartan or olmesartan, and followed the patients for 3 months. Systolic BP (SBP) in the azilsartan group was significantly decreased at 3 months, and diastolic BP (DBP) and pulse rate (PR) in the olmesartan group showed significant reductions after 3 months. There were no significant differences in ΔSBP, ΔDBP, or ΔPR (Δ = the value at 3 months minus the value at 0 months) between the groups. Serum levels of creatinine (Cr), uric acid (UA), and potassium (K) in the azilsartan group significantly increased after 3 months. While the changes in Cr, UA, and K were within the respective normal ranges, ΔSBP was positively associated with ΔCr in the azilsartan group. In conclusion, there was no difference in the depressor effects of azilsartan and olmesartan, and there were no serious changes in biochemical parameters with azilsartan and olmesartan.

An ongoing discussion is whether using a hydroxyapatite coating enhances the ingrowth and longevity of a femoral stem in total hip arthroplasty. The best way to predict speed of ingrowth and long-term outcome is by evaluating micromotion by radiostereometric analysis. To study the effect of hydroxyapatite (HA) coating on the migration of the SL-PLUS hip stem, we performed a prospective double blind randomised controlled trial comparing the early migration of the hydroxyapatite (HA)-coated SL-PLUS stem compared to the Standard (non-coated) SL-PLUS stem. 51 patients were randomly assigned to receive either an uncoated or a HA-coated femoral component during total hip replacement. RSA images were obtained direct postoperatively and at 6 weeks, 12 weeks, 6 months, 12 months and 24 months. HOOS scores were obtained preoperative and at final follow-up. RSA evaluation demonstrated significant migration up to 3 months postoperatively in both groups. After initial setting no significant migration was observed. There was no significant difference in migration between the HA-coated group and the uncoated group.Both Harris Hip Score (HHS) and HOOS domain scores (pain and ADL) significantly improved compared to baseline at 24 months after surgery in both treatment groups (p<0.001 for all comparisons). Improvement did not differ significantly between the 2 groups. At 2 years follow-up, the HA-coated and uncoated Zweymuller type, distal fitting stem do not show different migration patterns.

To evaluate the clinical outcomes of intentionally replanted maxillary single-rooted teeth with vertical root fractures (VRFs) after being repaired extraorally using 4-methacryloxyethyl trimellitate anhydride/methacrylate-tri-n-butyl borane (4-META/MMA-TBB) resin cement. Twenty-one root filled maxillary single-rooted teeth with VRFs were evaluated. After atraumatic extraction, fractured fragments were adhesively cemented. The teeth were then replanted and splinted to the neighbouring teeth for 2 weeks. Plaque index (PI), gingival index (GI), probing depth (PD) and clinical attachment level (CAL) were assessed at baseline, 6 and 12 months, and radiographic evaluations were made using PAI scores at baseline and 12 months. Mobility was evaluated using periotest values (PTV) at baseline, 1, 3, 6 and 12 months. Replanted teeth, contralateral teeth (control teeth) and adjacent teeth were analysed statistically using repeated measures one-way anova, unpaired t-tests and Wilcoxon matched-pairs signed-rank tests. Two teeth were extracted in the first month after surgery. PI, GI, CAL and PD scores of the replanted teeth were significantly lower at 6 month (P < 0.0001 for all) and 12 month (P < 0.0001 for all) postoperatively when compared to baseline, but the values were not significantly different from those of the control and adjacent teeth. PTV of the test teeth increased significantly (P < 0.0001) after the intervention and decreased to baseline levels by month 12. PTVs were significantly higher (P < 0.05) at baseline, 1, 3 and 6 months in the test teeth when compared with the control teeth, but were not significantly different at month 12. PAI scores of teeth with VRF were significantly lower (P < 0.05) at 12 months compared with baseline. Adhesive cementation and intentional replantation were an effective treatment modality for this group of vertically fractured maxillary single-rooted teeth. The clinical periodontal parameters decrease by month 6, and the mobility returned to the physiological limits of natural teeth 12 months after replantation. © 2015 International Endodontic Journal.

To investigate whether internal iliac artery ligation (IIAL) for postpartum hemorrhage (PPH) affects the sexual life in the postpartum period or significantly reduces the clitoral artery blood flow. The women who underwent IIAL due to PPH during cesarean section (CS) were compared with healthy postpartum women delivered by CS between October 2014 and February 2016 in the Gaziantep Women's Health and Maternity Hospital, Gaziantep, Turkey. Clitoral Doppler flow measurements and the Female Sexual Function Index questionnaire (FSFIQ) were performed in all women in the 3rd and 6th postpartum months. This study was registered at ClinicalTrials.gov with the identification number NCT02409602. Mean age, gravidity and parity, body mass index (BMI), first sexual intercourse after childbirth, and education years were similar in both groups. There was no statistically significant difference in the measurements of RI, PI, PSV, EDV, and S/D between the study and control groups in the 3rd month. Lack of statistical significance was also noted between the study and control groups values in the 6th month, as well as between the 3rd and 6th month's values within both the study group and the control group. Additionally, there were no statistically significant differences in the total FSFI scores including sexual desire, sexual arousal, lubrication, orgasm, sexual satisfaction, and pain domain scores between the study and control groups in the 3rd month; between the study and control groups 6th months; whereas all scores were higher in the 6th month compared to the 3rd month within each group. IIAL does not affect the blood flow of the dorsal clitoral artery between the 3rd and 6th months postpartum and between the women who underwent IIAL due to PPH and healthy postpartum women. The sexual function scores were significantly higher in the 6th month compared to the 3rd month in both groups. Copyright © 2017 Elsevier B.V. All rights reserved.

To assess the effectiveness of delayed surgery and follow-up observation in managing severe Bell's palsy after two months of onset. Forty-one Bell's palsy patients with severe facial paralysis were treated after two months of onset. Eighteen patients in group I underwent decompression operations between two and three months after onset, and eight patients in group II underwent surgery after three months of onset; 15 patients in group III were managed with follow-up observation. All patients were followed up at the end of 3rd, 6th and 12th months, and surgical outcomes were compared with follow-up observations using House-Brackmann score and Facial Clinimetric Evaluation (FaCE) scale. Between groups I and III, the difference in the proportion of the patients with fair or poor recoveries was statistically significant (p < 0.05) at the three-month follow-up visit. There was no significant difference in the distribution of complete, fair or poor recoveries at the 12-month follow-up visits among the three groups (p < 0.05). The total FaCE score and five individual domains were significantly improved at the end of the follow-up period in groups I and III (p < 0.05). However, in group I, the lacrimal control scores were significantly decreased at the end of the follow-up period compared to scores before surgery (p < 0.05). After surgery, four patients had sensorineural hearing loss, three patients had tinnitus and no patients had vertigo. Patients with severe Bell's palsy after two months of onset would not benefit from delayed decompression surgery.

Professional vocalists encounter demands requiring voluntary control of phonation, while utilizing a considerable range of frequency and intensity. These quantifiable acoustic events can be measured and represented in a phonetogram. Previous research has compared the phonetograms of trained and untrained voices and found significant differences between these groups. This study was designed to assess the effects of vocal training for singers over a period of nine months. Phonetogram contour changes were examined, with the primary focus on expansion of frequency range and/or intensity control. Twenty-one first-year, master's level, vocal music students, who were engaged in an intensive vocal performance curriculum, participated in this study. Following nine months of vocal training, significant differences were revealed in the subjects' mean frequency range and minimum vocal intensity across frequency levels. There was no significant difference for the mean maximum vocal intensity across frequency levels following vocal training.

Quantitative, longitudinal design. Neonatal Intensive Care Unit of two Canadian urban hospitals. Sixty-one couples who had an infant born weighing less than 1,500 g. State-Trait Anxiety Inventory, Parenting Sense of Competence questionnaire, and the Support in Parenting Questionnaire were completed at 3 and 9 months of age. Parent-infant interaction was observed at 9 months and scored with the Nursing Child Assessment Teaching Scale. Fathers' reported parenting self-efficacy was significantly lower than mothers' at both 3 and 9 months of age. Fathers reported more received support than mothers, and the amount of support that both mothers and fathers reported increased significantly from the 3-month to the 9-month assessment. Mothers and fathers reported similar levels of anxiety and perceived helpfulness of the support they received and were equally sensitive and responsive in interactions with their infants at 9 months of age. Similarities and differences between mothers and fathers were observed. It is important for nurses to assess mothers and fathers, how any differences are perceived by the couple, and how any differences might be affecting them during the neonatal intensive care unit hospitalization and in early months after discharge.

To assess possible delayed recovery of the maximum speech discrimination score (SDS) when the audiometric threshold ceases to change. We retrospectively examined 20 patients with idiopathic sudden sensorineural hearing loss (ISSNHL) (gender: 9 males and 11 females, age: 24-71 years). The findings of pure-tone average (PTA), maximum SDS, auditory brainstem responses (ABRs), and tinnitus handicap inventory (THI) were compared among the three periods of 1-3 months, 6-8 months, and 11-13 months after ISSNHL onset. No significant differences were noted in PTA, whereas an increase of greater than or equal to 10% in maximum SDS was recognized in 9 patients (45%) from the period of 1-3 months to the period of 11-13 months. Four of the 9 patients showed 20% or more recovery of maximum SDS. No significant differences were observed in the interpeak latency difference between waves I and V and the interaural latency difference of wave V in ABRs, whereas an improvement in the THI grade was recognized in 11 patients (55%) from the period of 1-3 months to the period of 11-13 months. The present study suggested the incidence of maximum SDS restoration over 1 year after ISSNHL onset. These findings may be because of the effects of auditory plasticity via the central auditory pathway. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Essential fatty acids for premenstrual syndrome and their effect on prolactin and total cholesterol levels: a randomized, double blind, placebo-controlled study

PubMed Central

2011-01-01

Objective To evaluate the effectiveness and safety of polyunsaturated fatty acids for the treatment of the premenstrual syndrome (PMS) using a graded symptom scale and to assess the effect of this treatment on basal plasma levels of prolactin and total cholesterol. Methods A randomized, double-blind, placebo-controlled study was conducted with 120 women with PMS divided into three groups and treated with 1 or 2 grams of the medication or placebo. Symptoms were recorded over a 6-month period using the Prospective Record of the Impact and Severity of Menstruation (PRISM) calendar. Total cholesterol and prolactin levels were measured. Analysis of variance (ANOVA), Pearson's chi-square test, Wilcoxon's nonparametric signed-rank test for paired samples and the Mann-Whitney nonparametric test for independent samples were used in the statistical analysis. Results There were no differences in age, marital status, schooling or ethnicity between the groups. In the group treated with 1 gram of the medication, a significant reduction was found when the median PRISM score recorded in the luteal phase at baseline (99) was compared with the median score recorded in the 3rd month (58) and in the 6th month of evaluation (35). In the 2-gram group, these differences were even more significant (baseline score: 98; 3rd month: 48; 6th month: 28). In the placebo group, there was a significant reduction at the 3rd but not at the 6th month (baseline: 96.5; 3rd month: 63.5; 6th month: 62). The difference between the phases of the menstrual cycle was greater in the 2-gram group compared to the group treated with 1 gram of the medication. There were no statistically significant differences in prolactin or total cholesterol levels between baseline values and those recorded after six months of treatment. Conclusion The difference between the groups using the medication and the placebo group with respect to the improvement in symptomatology appears to indicate the effectiveness of the drug. Improvement in symptoms was higher when the 2-gram dose was used. This medication was not associated with any changes in prolactin or total cholesterol levels in these women. PMID:21241460

Objective This study compares the results of an objective structured clinical examination (OSCE) between 2 groups of students before an internship and after 6 months of clinical practice in an internship. Methods Seventy-two students participated, with 36 students in each cohort. The OSCEs were performed in the simulation laboratory before the participants' clinical practice internship and after 6 months of the internship. Students were tested in 9 stations for clinical skills and knowledge. The same procedures were repeated for both cohorts. The t test was used for unpaired parametric samples and Fisher's exact test was used for comparison of proportions. Results There was no difference in the mean final score between the 2 groups (p = .34 for test 1; p = .08 for test 2). The performance of the students in group 1 was not significantly different when performed before and after 6 months of clinical practice, but in group 2 there was a significant decrease in the average score after 6 months of clinical practice. Conclusions There was no difference in the cumulative average score for the 2 groups before and after 6 months of clinical practice in the internship. There were differences within the cohorts, however, with a significant decrease in the average score in group 2. Issues pertaining to test standardization and student motivation for test 2 may have influenced the scores. PMID:25588200

This outcome study compared six- and 12-month return-to-custody data for 171 treatment participants and 145 nontreated general population inmates at the Central California Women's Facility (implementing a traditional TC program). Findings showed that there were no differences between the TC treatment group and the no treatment comparison group with regard to six- and 12-month return-to-custody rates (six-month: 16% vs. 16% and 12-month: 36% vs. 27%). The only significant difference in six-month return-to-custody rates was found between treatment-only participants (21%) and the treatment plus aftercare participants (6%). Treatment participants who participated in community-based aftercare were significantly less likely to be returned to custody compared with those who did not participate in aftercare. Multivariate analysis was also used to control for the large difference in psychological impairment between the two groups and other background factors related to reincarceration, while assessing the effect of treatment group status on return-to-custody. Findings indicated that treatment/no-treatment status was not significantly related to a six- or 12-month return-to-custody. However, success on parole was associated with participation in community-based aftercare. The lack of a prison-based treatment effect could be an indication that drug-dependent women offenders need gender-responsive treatment that is designed specifically for their complex needs.

Objective Examine the effect of weekday exposure over six months to different lunch sizes on energy intake and body weight in a free-living sample of working adults. Design and Methods Adults (n=233) were randomly assigned to one of three lunch size groups (400 kcal; 800 kcal; 1600 kcal) or to a no-free lunch control group for six months. Weight and energy intake were measured at baseline, and months 1, 3, and 6. Results Lunch energy was significantly higher in the 800 and 1600 kcal groups compared to the 400 kcal group (p < 0.0001). Total energy was significantly higher for the 1600 kcal group compared to the 400 and 800 kcal groups (p = 0.02). Body weight change at six months did not significantly differ at the 5% level by experimental group (1600 kcal group: +1.1 kg (sd=0.44); 800 kcal group: −0.1 kg (sd=0.42); 400 kcal group: −0.1 kg (sd=0.43); control group: 1.1 (sd=0.42); p=.07). Weight gain over time was significant in the 1600 kcal box lunch group (p < 0.05). Conclusions Weekday exposure for six months to a 1600 kcal lunch caused significant increases in total energy intake and weight gain. PMID:24510841

In total knee arthroplasty (TKA), dynamic knee loading may loosen the artificial joint and bone or cause polyethylene wear after prolonged use. TKA decreases knee adduction moment at 6 months, but this effect is lost by 1 year post-operatively. However, lateral thrust after TKA has not been clarified. We hypothesized that like knee adduction moment, lateral thrust would return to baseline levels by 1 year post-operatively. Participants were 15 patients who underwent TKA for medial knee OA. Japanese Orthopaedic Association (JOA) score, numeric rating scale, and gait analysis (measurement of peak knee adduction moment, knee varus angle at peak knee adduction moment, lateral thrust, and gait speed) were performed preoperatively (baseline) and 3 weeks, 3 and 6 months, and 1 year post-operatively. JOA score improved from 55 ± 9.8 to 78 ± 12.1 at 1 year post-operatively, and pain decreased significantly from baseline at each follow-up (p < 0.001). Significant increases in gait speed were observed at 6 months and 1 year (p < 0.001). Peak knee adduction moment during stance phase was significantly lower at 3 weeks, 3 months, and 6 months compared to baseline (p < 0.05), but no significant changes were seen at 1 year. Knee varus at peak knee adduction moment did not differ significantly between any measurement points, while lateral thrust was decreased at 6 months and 1 year compared to baseline (p < 0.05). Temporal courses of changes up to 1 year after TKA differed between knee adduction moment and lateral thrust, so our hypothesis was rejected. IV.

Results of endovascular aneurysm repair (EVAR) may be gender dependent. Between September 1997 and September 2001, 118 AneuRx aortic grafts were placed for aneurysmal disease. During this period, 17 females and 101 males were treated with this device. A prospective database was maintained and supplemented with retrospectively gathered information to evaluate early and mid-term end points. A total of 113 devices were deployed in 118 attempts. Length of procedure was greater for females (3.3 +/- 1.75 vs. 2.3 +/- 0.8 hr, p = 0.05) and they were more likely to have significant arterial dissections (12% vs. 1%, p = 0.05). The mortality rates at 1 month were 12% for females and 0% for males ( p = 0.02); the complication rates at 1 month were 41% for females and 15% for males ( p = 0.02). Although technical success was not significantly different between the sexes, assisted primary technical success (requiring endovascular assistance) and assisted secondary technical success (requiring open surgical assistance) were significantly different (71% vs. 96%, p = 0.003; and 76% vs. 98%, p = 0.004, respectively). Clinical success at 1 month was 59% for females and 84% for males ( p = 0.02). This difference was also significant when assessing 1-month assisted primary clinical success (59% vs. 90%, p = 0.003) and assisted secondary clinical success as well (71% vs. 96%, p = 0.003). Clinical success and assisted primary clinical success were not different at 6- or 12-month intervals, however, assisted secondary clinical successes differed at both time intervals (56% vs. 83%, p = 0.02; and 56% vs. 81%, p = 0.05, respectively). As-yet undetermined factors appear to predispose females to complications and technical difficulties in the short term. Endovascular and open procedures required to achieve ongoing clinical success in the following months appear to favor males to a greater degree than females.

To investigate the effect of different inner metal materials of porcelain-fused-to-metal (PFM) crown on periodontal tissue by means of measuring the level of soluble intercellular adhesion molecule-1 (sICAM-1) and interleukin-1beta (IL-1beta) in gingival crevicular fluid (GCF) after PFM restorations. 30 teeth were divided into three groups (Ni-Cr alloy group, Co-Cr alloy group and Au-Pt alloy group, 10 teeth each group), and restored by Ni-Cr alloy, Co-Cr alloy and Au-Pt alloy PFM crown according grouping. At the point of pre-restoration, 6-month and 12-month after cementation, the clinical parameters including plaque index (PLI), gingival index (GI) and gingival crevice depth (GCD) were detected, and GCF was collected from labial and lingual of mesial site and distal site. The level of sICAM-1 and IL-1beta were detected. At the point of 6-month and 12-month after cementation, Ni-Cr alloy group showed significant difference for GI, GCD and all GCF indexes when compared to pre-restoration, Co-Cr alloy group and Au-Pt alloy group (P < 0.05). At the point of 12-month after cementation, Co-Cr alloy group showed significant difference for GI, GCD and all GCF indexes when compared to pre-restoration and Au-Pt alloy group (P < 0.05). All indexes have no significant difference for Au-Pt alloy group during the 12-month experiment times when compared to pre-restoration (P > 0.05). Non-noble metal has bad effect on the periodontal tissue.

The following study aims to evaluate the monotherapy with biologic agents: Infliximab (IFX), Etanercept (ETA), Adalimumab (ADA) and Rituximab (RTX) in patients diagnosed with rheumatoid arthritis (RA). To achieve these objectives, the database of "Dr. I. Cantacuzino" Clinical Hospital, Department of Internal Medicine and Rheumatology, was used. The study was retrospective and descriptive, covering 168 patients with RA, followed for 12 months, from January 2012 to January 2013. Admission criteria for the study were the following: patients diagnosed with RA according to ACR 1987/ EULAR 2010 criteria, disease activity score (DAS 28)> 5.1, positive inflammation tests, presence of RA refractory to classic remitting treatment administered at least 6 months prior to the initiation of biological therapy, on patients treated with RTX. They were considered non-responders after 6 months of treatment with anti tumor necrosis factor alpha (anti-TNF) and decided to switch agents with anti CD-20. Comparing values between any two points in time (baseline - 6 months -12 months) for any type of therapy, there were significant decreases in the values of erythrocyte sedimentation rate (ESR), reactive C protein (CRP) and disease activity score (DAS 28). There were no significant differences between therapies regarding ESR at 6 months (p = 0.070, ANOVA) and 12 months (p = 0.375, Kruskal-Wallis), significant differences were regarding CRP at 6 and 12 months (p = 0.000, Kruskal-Wallis) and DAS 28 at 6 months (p = 0.000, Kruskal- Wallis) and 12 months (p = 0.018, Kruskal-Wallis). All 4 therapies have proven efficient, prognostic markers decreasing gradually at 6 and 12 months.

To assess whether percutaneous vertebroplasty results in more pain relief than a sham procedure in patients with acute osteoporotic compression fractures of the vertebral body. Randomised, double blind, sham controlled clinical trial. Four community hospitals in the Netherlands, 2011-15. 180 participants requiring treatment for acute osteoporotic vertebral compression fractures were randomised to either vertebroplasty (n=91) or a sham procedure (n=89). Participants received local subcutaneous lidocaine (lignocaine) and bupivacaine at each pedicle. The vertebroplasty group also received cementation, which was simulated in the sham procedure group. Main outcome measure was mean reduction in visual analogue scale (VAS) scores at one day, one week, and one, three, six, and 12 months. Clinically significant pain relief was defined as a decrease of 1.5 points in VAS scores from baseline. Secondary outcome measures were the differences between groups for changes in the quality of life for osteoporosis and Roland-Morris disability questionnaire scores during 12 months' follow-up. The mean reduction in VAS score was statistically significant in the vertebroplasty and sham procedure groups at all follow-up points after the procedure compared with baseline. The mean difference in VAS scores between groups was 0.20 (95% confidence interval -0.53 to 0.94) at baseline, -0.43 (-1.17 to 0.31) at one day, -0.11 (-0.85 to 0.63) at one week, 0.41 (-0.33 to 1.15) at one month, 0.21 (-0.54 to 0.96) at three months, 0.39 (-0.37 to 1.15) at six months, and 0.45 (-0.37 to 1.24) at 12 months. These changes in VAS scores did not, however, differ statistically significantly between the groups during 12 months' follow-up. The results for secondary outcomes were not statistically significant. Use of analgesics (non-opioids, weak opioids, strong opioids) decreased statistically significantly in both groups at all time points, with no statistically significant differences between groups. Two adverse events occurred in the vertebroplasty group: one respiratory insufficiency and one vasovagal reaction. Percutaneous vertebroplasty did not result in statistically significantly greater pain relief than a sham procedure during 12 months' follow-up among patients with acute osteoporotic vertebral compression fractures.

To investigate long-term intraocular pressure trends after uncomplicated pars plana vitrectomy for idiopathic epiretinal membrane. Three hundred and sixty-eight eyes of 368 consecutive patients were enrolled. Changes in intraocular pressure 1, 3, 6, and 12 months after surgery and during the final follow-up visit were evaluated in vitrectomized eyes and nonvitrectomized fellow eyes. The median follow-up period was 36 months (range 12-92 months). Longitudinal data analysis evidenced a 2.5-mmHg (2.2 mmHg; 2.7 mmHg, 95% confidence interval) statistically significant difference in intraocular pressure 30 days after surgery between treated and fellow untreated eyes, gradually recovering to a not significant 0.2-mmHg (-0.1 mmHg; 0.4 mmHg, 95% confidence interval) difference within 26 months. The incidence of late-onset ocular hypertension was 5.7% (21 over 347, 2%; 12%, 95% confidence interval) without difference between the treated eyes and the group control. No significant difference in the incidence of late-onset ocular hypertension and sex, lens status, or gauge of vitrectomy instruments was detected. Only patient's age was significantly higher (mean difference 4.2 years; 0.1-8.0 years, Monte Carlo, 95% confidence interval) in those who developed late-onset ocular hypertension in the vitrectomized eye. Uncomplicated pars plana vitrectomy for idiopathic epiretinal membrane seems not to increase the risk of late-onset ocular hypertension or open-angle glaucoma development.

The cognitive and language skills of 30 siblings of children with autism (SIBS-A) and 30 siblings of typically developing children (SIBS-TD) were compared. Non-significant group differences emerged for cognition at both ages. At 24 months, significantly more SIBS-A demonstrated language scores one or two standard deviations below the mean compared to SIBS-TD. At 36 months, the groups differed significantly in receptive language, and more SIBS-A displayed receptive and expressive difficulties compared to SIBS-TD. Six SIBS-A (including one diagnosed with autism) revealed language scores more than two standard deviations below the mean at both ages, a pattern not seen in the SIBS-TD. Results are discussed in reference to language difficulties in autism spectrum disorders and the genetic liability for autism.

Despite the growing tendency toward tooth-colored restorations in dentistry, polymerization shrinkage and subsequent marginal microleakage remains a problem. The aim of this in vitro study was to compare microleakage between silorane-based and methacrylate-based composite resins at different time intervals and with different restorative techniques. In this in vitro study, 108 sound extracted human molar teeth were used. Mesial and distal proximal class II boxes with dimensions of 1.5 mm depth and 4 mm width were prepared. The gingival margins of all cavities were 1 mm below the cement enamel junction. The teeth were randomly divided into three groups based on test materials. In the first group, the teeth were restored by a nanocomposite (Filtek Z350XT, 3MESPE) and SE Bond adhesive (Kuraray, Japan), in the second group, the teeth were restored with a silorane-based (Filtek P90, 3MESPE) and Filtek P90 Adhesive (3M ESPE, USA) and in the third group, the teeth were restored with a microhybrid posterior composite resin (Filtek P60, 3MESPE) and SE Bond adhesive (Kuraray, Japan). Half of the proximal cavities in each of these three groups were restored in two horizontal layers and the other half in four horizontal layers. After a period of aging (24-h, 3-month and 6-month) in water and then application of 500 thermal cycles, the teeth were immersed for 24-h in 0.5% fuchsin and evaluated under a stereomicroscope at ×36 magnification to evaluate leakage in gingival margin. Data was statistically analyzed using Kruskal-Wallis and Mann-Whitney U-tests. P ≤ 0.05 was considered as significant. In Z350XT statistically significant differences were observed in microleakage in comparison of 24-h and 6-month intervals (P = 0.01) that was higher in 6-month. Comparison of microleakage in P90 and P60 composite resins was also statistically significant and was less in P90. Microleakage was not significantly different between P90 and Z350XT at 24-h. However, this difference was significant at 3-month and 6-month intervals. Differences in microleakage of P60 and Z-350XT composite resins were not statistically significant in all intervals (P = 0.38). P90 showed the lowest microleakage during storage in water. Z350XT had microleakage similar to P90 within 24-h, but after 6-month of storage in water, it showed the highest microleakage among all the groups. The number of layers (2 layers vs. 4 layers) did not result in any differences in microleakage scores of the composite resins (P = 0.42). Water storage times did not result in any significant effect on microleakage of P90 and P60.

The aim of this controlled, parallel design clinical study was to compare the effectiveness of an Er:YAG laser (ERL) to that of mechanical debridement using plastic curettes and antiseptic therapy for nonsurgical treatment of peri-implantitis. Twenty patients with moderate to advanced peri-implantitis lesions were randomly treated with either (1) an ERL using a cone-shaped glass fiber tip at an energy setting of 100 mJ/pulse and 10 pps (ERL), or (2) mechanical debridement using plastic curettes and antiseptic therapy with chlorhexidine digluconate (0.2%) (C). The following clinical parameters were measured at baseline, 3 and 6 months after treatment by one blinded and calibrated examiner: Plaque index (PI), bleeding on probing (BOP), probing depth (PD), gingival recession (GR) and clinical attachment level (CAL). At the baseline examination, there were no statistically significant differences in any of the investigated parameters. Mean value of BOP decreased in the ERL group from 83% at baseline to 31% after 6 months (P < 0.001) and in the C group from 80% at baseline to 58% after 6 months (P < 0.001). The difference between the two groups was statistically significant (P < 0.001, respectively). The sites treated with ERL demonstrated a mean CAL change from 5.8 +/- 1 mm at baseline to 5.1 +/- 1.1 mm (P < 0.01) after 6 months. The C sites demonstrated a mean CAL change from 6.2 +/- 1.5 mm at baseline to 5.6 +/- 1.6 mm (P < 0.001) after 6 months. After 6 months, the difference between the two groups was statistically not significant (P > 0.05). Within the limits of the present study, it was concluded that (i) at 6 months following treatment both therapies led to significant improvements of the investigated clinical parameters, and (ii) ERL resulted in a statistically significant higher reduction of BOP than C.

In this four-site clinical trial, we evaluated whether tinnitus masking (TM) and tinnitus retraining therapy (TRT) decreased tinnitus severity more than the two control groups: an attention-control group that received tinnitus educational counseling (and hearing aids if needed; TED), and a 6-month-wait-list control (WLC) group. The authors hypothesized that, over the first 6 months of treatment, TM and TRT would decrease tinnitus severity in Veterans relative to TED and WLC, and that TED would decrease tinnitus severity relative to WLC. The authors also hypothesized that, over 18 months of treatment, TM and TRT would decrease tinnitus severity relative to TED. Treatment effectiveness was hypothesized not to be different across the four sites. Across four Veterans affairs medical center sites, N = 148 qualifying Veterans who experienced sufficiently bothersome tinnitus were randomized into one of the four groups. The 115 Veterans assigned to TM (n = 42), TRT (n = 34), and TED (n = 39) were considered immediate-treatment subjects; they received comparable time and attention from audiologists. The 33 Veterans assigned to WLC were, after 6 months, randomized to receive delayed treatment in TM, TRT, or TED. Assessment of outcomes took place using the Tinnitus Handicap Inventory (THI) at 0, 3, 6, 12, and 18 months. Results of a repeated measures analysis of variance using an intention-to-treat approach showed that the tinnitus severity of Veterans receiving TM, TRT, and TED significantly decreased (p < 0.05) relative to Veterans in the WLC group at 3 months (effect sizes = 0.44, 0.52, and 0.27, respectively) and at 6 months (effect sizes = 0.52, 0.56, and 0.40, respectively). Analyses comparing effectiveness of TM, TRT, and TED over 18 months revealed that the three conditions were not significantly different, but that tinnitus severity in the combined groups significantly decreased (p < 0.01) from baseline to 3 months (5.6 THI points) and from 3 to 6 months (3.7 THI points). With respect to clinically significant change, about half of Veterans who received TM (55%), TRT (59%), or TED (46%) showed strong or modest improvement on the THI by 18 months. Without treatment, the WLC group did not show significant change. Treatment effectiveness did not differ by study site. Audiologists who provided interventions to Veterans with bothersome tinnitus in the regular clinic setting were able to significantly reduce tinnitus severity over 18 months using TM, TRT, and TED approaches. These results suggest that TM, TRT, and TED, when implemented as in this trial, will provide effectiveness that is relatively similar by 6 months and beyond.

A detailed knowledge of dysphagia outcomes in lateral medullary infarct (LMI) patients would enable proper establishment of swallowing therapy goals and strategies. However, little is known about the impact of infarct location on dysphagia outcomes in patients with LMI. Twenty patients with rostral LMI (rostral group) and 20 patients with caudal LMI (caudal group) participated in the study. All patients underwent swallowing therapy, which included compensatory treatments and strengthening exercises, for >3 months. Dysphagia evaluation was performed twice (during the subacute stage and six months after stroke onset) using videofluoroscopic swallowing studies. Dysphagia degree was assessed using the functional dysphagia scale (FDS), the penetration-aspiration scale (PAS) and the American Speech-Language-Hearing Association (ASHA) National Outcome Measurement System (NOMS) swallowing scale. In the subacute stage, the rostral group had significantly higher FDS and PAS scores and a significantly lower ASHA NOMS score than the caudal group. Patients from both groups showed significant improvement from the initial evaluation to the six-month evaluation. There were no significant differences in these scale scores between the two groups at the six-month evaluation. In the subacute stage, patients in the rostral group had more severe dysphagia than those in the caudal group. Dysphagia improved in both groups after 3-6 months of swallowing therapy. At six months after onset, there were no significant differences in dysphagia severity between the two groups. Recovery from dysphagia after LMI was observed regardless of the infarct location.

Mental health is of great importance in childhood and the foundation of personality of every individual is laid during this period. Moreover, behavioral problems are common in children, and a lot of the individual, familial, and social disorders originate from the fact that these problems are not treated at the right time. More important is that the behavioral problems of children are rooted in the behavior and upbringing of parents. Therefore, we carried out the present study to investigate the role of community health nurses in modifying the behavior of parents whose children have behavioral problems. This research was a pre- and post-training quasi-experimental study. The study was carried out with the participation of the parents of 44 first-grade primary school children with reported behavioral problems. The instrument used in the study was a self-made questionnaire. The data was analyzed by SPSS software, using descriptive and inferential statistical methods (t-test and repeated ANOVA). The mean scores of parents' behavior before, immediately after, and one month after training exhibited a significant difference in both fathers and mothers (p = 0.04 in fathers and p < 0.001 in mothers). Moreover, the mean scores of mothers before and immediately after training and also before and one month after training showed a significant difference (p < 0.001 and p < 0.001, respectively). However, the mean scores of mothers immediately after and one month after training were not significantly different (p=0.53). Furthermore, the mean scores of fathers before and immediately after training and also before and one month after training were significantly different (p < 0.001 and p < 0.001, respectively). But, the mean scores of fathers immediately after and one month after training did not show a significant difference (p = 0.33). Since the group training of parents led to a change in their behavior towards children, it is advisable to prepare and implement such programs.

We compared the perioperative and postoperative characteristics of thulium vapoenucleation and holmium laser enucleation of the prostate for the treatment of large volume benign prostatic hyperplasia. A total of 94 patients with benign prostatic hyperplasia and a median prostate size of 80 (IQR 46.75-100) cc were either randomized to thulium vapoenucleation or holmium laser enucleation of the prostate. Patients were assessed preoperatively, 1 and 6 months postoperatively. The median operative time was 60 (IQR 41-79) min without significant differences between the groups. There were no significant differences between the groups regarding catheter time [2 (IQR 2-2) days] and postoperative stay [2 (IQR 2-3) days]. Clavien 1 (13.8%), 2 (3.2%), 3a (2.1%), and Clavien 3b (4.3%) complications occurred without significant differences between the groups. At 6-month follow-up, median maximum flow rate (10.7 vs. 25.9 ml/s), post-void residual urine (100 vs. 6.5 ml), I-PSS (20 vs. 5), quality of life (4 vs. 1), PSA (4.14 vs. 0.71 µg/l), and prostate volume (80 vs. 16 ml) had improved significantly (p < 0.001) compared to baseline without significant differences between the groups. Median PSA decrease was 79.7% (58.8-90.6%) and prostate volume reduction was 74.5% (68.57-87.63%) without differences between the groups. The reoperation rate was zero at 6-month follow-up. Thulium vapoenucleation and holmium laser enucleation of the prostate are safe and effective procedures for the treatment of large volume benign prostatic hyperplasia. Both procedures give satisfactory micturition improvement with low morbidity and sufficient prostate volume reduction at 6-month follow-up.

Social cognition in infancy is evident in coordinated triadic engagements, that is, infants attending jointly with social partners and objects. Current evolutionary theories of primate social cognition tend to highlight species differences in cognition based on human-unique cooperative motives. We consider a developmental model in which engagement experiences produce differential outcomes. We conducted a 10-year-long study in which two groups of laboratory-raised chimpanzee infants were given quantifiably different engagement experiences. Joint attention, cooperativeness, affect, and different levels of cognition were measured in 5- to 12-month-old chimpanzees, and compared to outcomes derived from a normative human database. We found that joint attention skills significantly improved across development for all infants, but by 12 months, the humans significantly surpassed the chimpanzees. We found that cooperativeness was stable in the humans, but by 12 months, the chimpanzee group given enriched engagement experiences significantly surpassed the humans. Past engagement experiences and concurrent affect were significant unique predictors of both joint attention and cooperativeness in 5- to 12-month-old chimpanzees. When engagement experiences and concurrent affect were statistically controlled, joint attention and cooperation were not associated. We explain differential social cognition outcomes in terms of the significant influences of previous engagement experiences and affect, in addition to cognition. Our study highlights developmental processes that underpin the emergence of social cognition in support of evolutionary continuity. PMID:24410843

To investigate the association between fundus autofluorescence (FAF) and visual acuity, recovery of foveal microstructure, and FAF in surgically closed macular holes. Twenty-six eyes with surgically closed macular hole were classified into two groups based on foveal FAF: normal autofluorescence (NAF) or increased autofluorescence (IAF). The association between foveal FAF and visual acuity was analyzed. In addition, we examined the relationship between recovery of the foveal microstructure assessed by spectral domain optical coherence tomography and FAF after macular hole surgery. At 1 month and 6 months after surgery, there were 9 NAF eyes and 17 IAF eyes. There were no differences between NAF and IAF eyes at 1 month and 6 months after surgery. Preoperative best-corrected visual acuity (logarithm of the minimum angle of resolution) did not differ between groups. Best-corrected visual acuity was significantly higher in the NAF group than in the IAF group at 1 month postoperatively (0.59 ± 0.34 vs. 0.91 ± 0.36, P = 0.044) and tended to be higher at 6 months (0.37 ± 0.38 vs. 0.69 ± 0.53, P = 0.126). Restoration of photoreceptor external limiting membrane differed significantly in 8 NAF eyes (89%) and 4 IAF eyes (24%) at postoperation 1 month (P = 0.001). After 6 months, external limiting membrane was restored in all 9 NAF eyes (100%) and in only 11 IAF eyes (65%) (P = 0.042). Fundus autofluorescence findings observed in surgically closed macular holes correlated with visual improvement and photoreceptor status. Eyes with visual improvement had restoration of normal foveal autofluorescence and retinal microstructure, whereas eyes with persistent foveal hyperautofluorescence did not achieve complete restoration of the retinal microstructure, and visual improvement was not as significant.

Low-birth-weight (LBW) infants (<2500 g) have an increased risk of iron deficiency (ID) during their first 6 months of life. The optimal dose and duration of iron supplementation to LBW infants are, however, unknown. The objective of the present study was to investigate the long-term effect on iron status and growth in marginally LBW (2000-2500 g) infants, of iron supplements given until 6 months of life. In a randomized controlled trial, 285 healthy marginally LBW infants received 0, 1, or 2 mg · kg(-1) · day(-1) of iron supplements from 6 weeks to 6 months of age. At 12 months and 3.5 years of life we measured length, weight, head circumference, and indicators of iron status (hemoglobin, ferritin, mean corpuscular volume, and transferrin saturation) and assessed the prevalence of iron depletion, functional ID, and ID anemia. At 12 months of age, there was a significant difference in ferritin between the groups (P = 0.006). Furthermore, there was a significant difference in the prevalence of iron depletion (23.7%, 10.6%, and 6.8%, respectively, in the placebo, 1-mg, and 2-mg groups, P = 0.009) and similar nonsignificant trends for functional ID and ID anemia. At 3.5 years of life there were no significant differences in iron status and the mean prevalence of iron depletion was 3.2%. Anthropometric data were not affected by the intervention. Iron supplements with 2 mg · kg(-1) · day(-1) until 6 months of life effectively reduces the risk of ID during the first 12 months of life and is an effective intervention for preventing early ID in marginally LBW infants.

This meta-analysis was performed to analyze serial changes in thigh muscles, including quadriceps and hamstring muscles, from before to one year after total knee arthroplasty (TKA). All studies sequentially comparing isokinetic quadriceps and hamstring muscle strengths between the TKA side and the contralateral uninjured limb were included in this meta-analysis. Five studies with 7 cohorts were included in this meta-analysis. The mean differences in the strengths of quadriceps and hamstring muscles between the TKA and uninjured sides were greatest three months after surgery (26.8 N∙m, 12.8 N∙m, P<0.001), but were similar to preoperative level at six months (18.4 N∙m, 7.4 N∙m P<0.001) and were maintained for up to one year (15.9 N∙m, 4.1 N∙m P<0.001). The pooled mean differences in changes in quadriceps and hamstring strengths relative to preoperative levels were 9.2 N∙m and 4.9 N∙m, respectively, three months postoperatively (P = 0.041), but were no longer significant after six months and one year. During the year after TKA, quadriceps and hamstring muscle strengths were lowest after 3 months, recovering to preoperative level after six months, but not reaching the muscle strength on the contralateral side. Relative to preoperative levels, the difference in muscle strength between the TKA and contralateral knees was only significant at three months. Because decrease of strength of the quadriceps was significantly greater than decrease in hamstring muscle strength at postoperative three months, early rehabilitation after TKA should focus on recovery of quadriceps muscle strength.

Discharge and water-quality data collection at East Branch Allen Creek from 1990 through 2000 provide a basis for estimating the effect of the Jefferson Road detention basin on loads and concentrations of chemical constituents downstream from the basin. Mean monthly flow for the 5 years prior to construction of the detention basin (8.71 ft3/s) was slightly lower than after (9.08 ft3/s). The slightly higher mean monthly flow after basin construction may have been influenced by the peak flow for the period of record that occurred in July 1998 or variations in flow diverted from the canal. No statistically significant difference in average monthly mean flow before and after basin installation was indicated.Total phosphorus was the only constituent to show no months with significant differences in load after basin construction. Several constituents showed months with significantly smaller loads after basin construction than before, whereas some constituents showed certain months with smaller and some months with greater loads, after basin construction. Statistical analysis of the "mean monthly load" for all months before and all months after construction of the detention basin showed only one constituent (ammonia + organic nitrogen) with a significantly lower load after construction and none with higher loads.Median concentrations of ammonia + organic nitrogen showed a statistically significant decrease (from 0.78 mg/L to 0.60 mg/L) after basin installation, as did nitrite + nitrate (from 1.50 mg/L to 0.96 mg/L); in contrast, the median concentration of dissolved chloride increased from 95.5 mg/L before basin installation to 109 mg/L thereafter. A trend analysis of constituent concentrations before and after installation of the detention basin showed that total phosphorus had a downward trend after installation.Analysis of the data collected at East Branch Allen Creek indicates that the Jefferson Road detention basin, in some cases, provides an improvement (reduction) in loads of some constituents. These results are uncertain, however, because hydrologic conditions before basin installation differed from those in the 5 years that followed, and because inflow from the Erie-Barge canal may alter the water quality in the 1-mi reach between the basin outflow and the gaging station.

The present study was conducted to evaluate the effects of FecB genotypes on body weight, average daily gain (ADG), ewe's productivity efficiency (EPE) and litter size in FecB introgressed GarolexMalpura (GM) crossbred sheep. A total of 235 GM lambs were selected randomly and screened for FecB mutation using forced RFLP-PCR. The majority (69.8%) of GM individuals were carriers (BB and B+) for the FecB mutation and frequency of the FecB allele was about 0.40. The FecB genotypes were significantly (P<0.01) associated with the lamb's body weights from birth to 12 months of age. The generation wise (F(1), F(2) and F(3)), lamb's body weight did not differ significantly at birth, 6 and 12 months of the age, while it differed significantly (P<0.05) at 3 and 9 months of age. The ADG1 (0-3 months) was significantly associated (P<0.05), but not the ADG2 (3-6 months) and ADG3 (6-12 months) between genotypes. Type of birth and sex significantly (P<0.01) affected the body weight from birth to 12 months of age; and body weight of single born lambs was significantly higher (P<0.01) than that of twins and triplets from birth to 12 months of age. Type of birth significantly (P<0.01) affected the ADG1, but had no significant effect on ADG2 and ADG3. Year of birth did not affect the birth and weaning weights, but it significantly affected (P<0.01) the body weight and ADG's after weaning ages. The EPE was affected significantly (P<0.01) by the FecB genotypes at birth, 3 and 12 months of age. The EPE of B+ and BB ewes were 7.86 kg (36.9%) and 2.32 kg (10.9%) higher as compared to ++ ewes at 12 months of age, respectively. The mean litter size of BB ewes (2.17+/-0.24) was significantly higher (P<0.01) than that of B+ ewes (1.73+/-0.04) and ++ ewes (1.03+/-0.23). The present study indicated that the body weight and ADG of carrier lambs (BB and B+) was comparatively lower than that of non-carriers (++), while EPE of B+ ewes was comparatively higher than that of BB and ++ ewes. Further, it is interesting to note that heterozygous and homozygous state of individuals increased 0.70 and 1.14 extra lambs as compared to non-carriers (++), respectively.

In this poster we applied the moving window approach (see Poster I of this collection) to analyze trends of summer and its corresponding months (June, July, August) temperature mean values of maximum (Tmax) and minimum (Tmin) in Spanish mainland to detect the effects of length period and starting year. Monthly series belong to Monthly Temperature dataset of Spanish mainland (MOTEDAS). Database contains in its grid format of 5236 pixels of monthly series (10x10 km). The threshold used in spatial analyses considers 20% of land under significant trend (p<0.05). The most striking results are as follow: • Tmax and Tmin seasonal trends affected mostly all the Spanish mainland, while the area affected decrease from 1983-2010 (Tmax) and 1987-2010 (Tmin). In both cases the areas affected significantly in recent decades are restricted to Eastern-coastland areas. • Monthly analyses show highly differences between Tmax and Tmin. Only June Tmax show significant trend in extended areas, and in fact from 70´s they are restricted to eastern coastland. Meanwhile both July and August Tmax trend affect particularly that area until mid 70´s. • Monthly trend analyses of Tmin show different patterns both in temporal windows and spatial distribution. Significant trend in June dominates practically all windows, while in July and August they predominate in south and eastern-Mediterranean coastland. No significant trend has been observed from middle of the 80´s (< 20% of area). In conclusion, summer trend analyses of Tmax and Tmin and their spatial distribution show clearly highly differences. In Tmax seasonal trend seems to be dominated by June Tmax behavior, while in Tmin the contribution of July and August must be considered particularly in southern and eastern-Mediterranean coastland. The most recent decades in Tmax and Tmin do not show significance, except in June Tmin.

We investigated the effects of the use of vitamin E-coated membrane (VEM) dialyzer in comparison to simvastatin on markers of chronic inflammation, oxidative stress, and endothelial cell apoptosis in ten patients on chronic hemodialysis (HD), aiming at distinguishing the different treatment effects and their time sequence on these pathogenetic routes. Ten HD patients were sequentially submitted to a 6-month treatment with the use of VEM and 10 mg of simvastatin daily, interrupted by a 3-month washout period. At baseline, at 3, and 6 months of each trial, serum C-reactive protein (CRP), apolipoprotein (Apo) A1 and B, lipoprotein-a [Lp(a)], high-sensitivity interleukin-6 (hsIL-6), monocyte chemoattractant protein-1 (MCP-1), soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1), soluble E-selectin (sE-selectin), soluble Fas (sFas), soluble Fas ligand (sFasL), and plasma oxidized low-density lipoproteins (oxLDL) levels were determined. VEM treatment resulted in a significant decrease in CRP, IL-6, sICAM-1 at 3 months, and oxLDL at 6 months, compared to baseline. Simvastatin resulted in a significant decrease in CRP, which correlated with decreases in both total (r = 0.87, p < 0.05) and low-density lipoprotein cholesterol, IL-6, sICAM-1, sVCAM-1, oxLDL, and sFas at 6 months, compared to baseline. Simvastatin effects on sVCAM-1 (mean difference = 652 ng/mL; 95% CI = 294 to 2686; p < 0.05) and sFas (mean difference = 1284 pg/mL; 95% CI = 510 to 1910; p < 0.05) differed significantly from the corresponding VEM effects. The 6-month use of VEM resulted in more direct and immediate anti-inflammatory effects compared with those caused by the 6-month treatment with simvastatin. Simvastatin caused a more intense decrease in the markers of inflammation, which was in part correlated with its lipid-lowering effects.

The aim of the study was to explore the effects of different fitness sports on cognitive function and emotion of the aged people. A total of 150 subjects aged between 60 and 70 were recruited from Shenyang Aged University and elderly activity center. All subjects reported no fitness before this study. The aged subjects were divided into five groups, included swimming group (A group), running group (B group), square dancing group (C group), Tai Chi group (D group) and control group (E group) with 30 people in each group. Subjects in each group received exercise intervention continued for 18 months. At baseline, 6, 12 and 18 months after intervention, the P300 test, SECF, HAMD and HAMA scale evaluations were performed. Compared to E group, the P2, N2 and P3 latency and response time in the D group after intervention for 6 months, and in the A-C groups after intervention for 12 months were significantly prolonged. The anxiety symptom and depression levels in the A-D groups after intervention for 12 months were significantly decreased when compared to E group (P < 0. 01), where significantly improved compared with the E group (P < 0. 01). The effect of exercise intervention for Tai Chi group was the most significant. Different fitness sports have marked beneficial effect on cognitive function and emotion of the aged people, especially the Tai Chi exercise.

Treatment with quarterly gonadotropin-releasing hormone (GnRH) analogs may improve compliance and optimize outcome in girls with central precocious puberty (CPP), but long-term comparative data between the new and the monthly formulations are very scarce. A group of girls with idiopathic CPP (n = 13; age 7.9 ± 0.6 years) were treated from the beginning with quarterly triptorelin (11.25 mg/90 days) and followed up to the achievement of adult height (AH). A group of girls with idiopathic CPP (n = 12; age 8.0 ± 0.6 years) treated with monthly triptorelin (3.75 mg/28 days) served as controls. The AH (157.1 ± 4.9 cm) of girls treated with quarterly triptorelin was not significantly different from their mid-parental height (159.7 ± 3.8 cm) and significantly increased in comparison with predicted AH (average tables) at the beginning of GnRH analog therapy. The AH of girls treated with quarterly triptorelin was not significantly different in comparison with that of girls treated with the monthly formulation (158.1 ± 6.6 cm; mid-parental height 158.4 ± 5.0 cm). Treatment with quarterly triptorelin formulation permitted to achieve an AH adequate for mid-parental height in girls with CPP. Significant differences of AH between girls with CPP treated with quarterly or monthly formulations were not found. © 2015 S. Karger AG, Basel.

With increased interest in the early diagnosis and treatment of children with autism spectrum disorders (ASD), more attention has been called to the motor skills of very young children with ASD. This study describes the gross and fine motor skills of a cross-sectional group of 162 children with ASD between the ages of 12 and 36 months, as well as a subset of 58 children followed longitudinally. Gross motor and fine motor age equivalent scores were obtained for all children. A 'motor difference' variable was calculated for each child's gross and fine motor skills by taking the absolute difference of the children's age equivalent motor score and their respective chronological age. In Study 1 (the cross-sectional analysis), ANCOVA (co-varied for nonverbal problem solving) revealed significant group differences in the gross motor and fine motor age difference variables. Post-hoc analysis revealed that gross motor and fine motor differences became significantly greater with each 6-month period of chronological age. In Study 2, 58 children were measured twice, an average of 12 months apart. Results indicate that the gross motor and fine motor difference scores significantly increased between the first and second measurements. The importance of addressing motor development in early intervention treatments is discussed.

The primary aim of this study was to determine whether different durations of contingency management (CM) in conjunction with psychosocial treatment produced different rates of abstinence among methamphetamine dependent individuals. Participants were randomized to one of the four 16-week treatment conditions: standard psychosocial treatment or psychosocial treatment plus one of the three durations of CM (one-month, two-month, or four-month). A total of 118 participants were randomized to the four treatment conditions. There were significant differences across treatment conditions for number of consecutive days of methamphetamine abstinence (p<0.05). These differences were in the hypothesized direction, as participants were more likely to remain abstinent through the 16-week trial as CM duration increased. A significant effect of treatment condition (p<0.05) and time (p<0.05) on abstinence over time was also found. Longer durations of CM were more effective for maintaining methamphetamine abstinence.

To determine (1) whether platelet-rich plasma (PRP) injection significantly improves validated patient-reported outcomes in patients with symptomatic knee osteoarthritis (OA) at 6 and 12 months postinjection, (2) differences in outcomes between PRP and corticosteroid injections or viscosupplementation or placebo injections at 6 and 12 months postinjection, and (3) similarities and differences in outcomes based on the PRP formulations used in the analyzed studies. PubMed, Cochrane Central Register of Controlled Trials, SCOPUS, and Sport Discus were searched for English-language, level I evidence, human in vivo studies on the treatment of symptomatic knee OA with intra-articular PRP compared with other options, with a minimum of 6 months of follow-up. A quality assessment of all articles was performed using the Modified Coleman Methodology Score (average, 83.3/100), and outcomes were analyzed using 2-proportion z-tests. Six articles (739 patients, 817 knees, 39% males, mean age of 59.9 years, with 38 weeks average follow-up) were analyzed. All studies met minimal clinical important difference criteria and showed significant improvements in statistical and clinical outcomes, including pain, physical function, and stiffness, with PRP. All but one study showed significant differences in clinical outcomes between PRP and hyaluronic acid (HA) or PRP and placebo in pain and function. Average pretreatment Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were 52.36 and 52.05 for the PRP and HA groups, respectively (P = .420). Mean post-treatment WOMAC scores for PRP were significantly better than for HA at 3 to 6 months (28.5 and 43.4, respectively; P = .0008) and at 6 to 12 months (22.8 and 38.1, respectively; P = .0062). None of the included studies used corticosteroids. In patients with symptomatic knee OA, PRP injection results in significant clinical improvements up to 12 months postinjection. Clinical outcomes and WOMAC scores are significantly better after PRP versus HA at 3 to 12 months postinjection. There is limited evidence for comparing leukocyte-rich versus leukocyte-poor PRP or PRP versus steroids in this study. Level I, systematic review of Level I studies.

Objective The objective was to determine whether treatments with demonstrated efficacy for binge eating disorder (BED) in specialist treatment centers can be delivered effectively in primary care settings to racially/ethnically diverse obese patients with BED. This study compared the effectiveness of self-help cognitive-behavioral therapy (shCBT) and an anti-obesity medication (sibutramine), alone and in combination, and it is only the second placebo-controlled trial of any medication for BED to evaluate longer-term effects after treatment discontinuation. Method 104 obese patients with BED (73% female, 55% non-white) were randomly assigned to one of four 16-week treatments (balanced 2-by-2 factorial design): sibutramine (N=26), placebo (N=27), shCBT+sibutramine (N=26), or shCBT+placebo (N=25). Medications were administered in double-blind fashion. Independent assessments were performed monthly throughout treatment, post-treatment, and at 6- and 12-month follow-ups (16 months after randomization). Results Mixed-models analyses revealed significant time and medication-by-time interaction effects for percent weight loss, with sibutramine but not placebo associated with significant change over time. Percent weight loss differed significantly between sibutramine and placebo by the third month of treatment and at post-treatment. After the medication was discontinued at post-treatment, weight re-gain occurred in sibutramine groups and percent weight loss no longer differed among the four treatments at 6- and 12-month follow-ups. For binge-eating, mixed-models revealed significant time and shCBT-by-time interaction effects: shCBT had significantly lower binge-eating frequency at 6-month follow-up but the treatments did not differ significantly at any other time point. Demographic factors did not significantly predict or moderate clinical outcomes. Discussion Our findings suggest that pure self-help CBT and sibutramine did not show long-term effectiveness relative to placebo for treating BED in racially/ethnically diverse obese patients in primary care. Overall, the treatments differed little with respect to binge-eating and associated outcomes. Sibutramine was associated with significantly greater acute weight loss than placebo and the observed weight-regain following discontinuation of medication suggests that anti-obesity medications need to be continued for weight loss maintenance. Demographic factors did not predict/moderate clinical outcomes in this diverse patient group. PMID:24857821

Objective: To investigate the current status of job stress in locomotive attendants in a locomotive depot and related influencing factors. Methods: From 2012 to 2013, cluster sampling was used to select 1500 locomotive attendants in a locomotive depot in Zhengzhou Railway Bureau as respondents.The contents of the investigation included general data and occupational information.A job satisfaction questionnaire was used to investigate the degree of satisfaction, a depression scale was used to investigate the frequency of symptoms, and a daily stress scale was used to investigate the frequency of fatigue and stress. Results: There was a significant difference in depression score between locomotive attendants with different ages, working years, degrees of education, working situations of spouse, total monthly family incomes, numbers of times of attendanceat night, monthly numbers of times of attendance,ormonthly attendance times( P <0.05). There was a significant difference in job satisfaction score between locomotive attendants with different ages,working years, degrees of education, working situations of spouse, total monthly family incomes, numbers of times of attendance at night, monthly attendance times,or ways to work( P <0.05). There was a significant difference in daily stress score between locomotive attendants with different ages, working years, marital status,working situations of spouse, total monthly family incomes, types of work,numbers of times of attendance at night,monthly attendance times,attendance times at night,or ways to work( P <0.05). The multiple stepwise regression analysis showed that the type of locomotive was positively correlated with job satisfaction( β =1.546)and monthly number of times of attendance,working years,attendance time at night,and degree of education were negatively correlated with job satisfaction( β =-0.185,-0.097,-0.020,and -1.106); monthly number of times of attendance andcommute time were positively correlated with depression( β =0.243 and 0.029); attendance time at night,working situation of spouse,commute time,monthly number of times of attendance,degree of education,and working years were positively correlated with daily stress( β =0.006,0.473,0.010,0.043,0.585, and 0.028). Conclusion: Number of times of attendance, attendance time,working years,and spouse are influencing factors for job stress in locomotive attendants. Improvement in work process and care for their personal life help to reduce the level of job stress.

Information about implantable cardioverter-defibrillator (ICD) longevity is mostly calculated from measurements under ideal laboratory conditions. However, little information about longevity under clinical circumstances is available. This survey gives an overview on ICD service times and generator replacements in a cohort of consecutive ICD patients. Indications for replacement were classified as a normal end-of-service (EOS), premature EOS, system malfunction, infection and device advisory, or recall actions. From the premature and normal EOS group, longevity from single-chamber (SC), dual-chamber (DC), and cardiac resynchronization therapy defibrillator (CRT-D), rate-responsive (RR) settings, high output (HO) stimulation, and indication for ICD therapy was compared. Differences between brands were compared as well. In a total of 854 patients, 203 ICD replacements (165 patients) were recorded. Premature and normal EOS replacements consisted of 32 SC, 98 DC and 24 CRT-D systems. Longevity was significantly longer in SC systems compared to DC and CRT-D systems (54 +/- 19 vs. 40 +/- 17 and 42 +/- 15 months; P = 0.008). Longevity between non-RR (n = 143) and RR (n = 11) settings was not significantly different (43 +/- 18 vs. 45 +/- 13 months) as it also was not for HO versus non-HO stimulation (43 +/- 19 vs. 46 +/- 17 months). Longevity of ICDs was not significantly different between primary and secondary prevention (42 +/- 19 vs. 44 +/- 18 months). The average longevity on account of a device-based EOS message was 43 +/- 18 months. Average longevity for Biotronik (BIO, n = 72) was 33 +/- 10 months, for ELA Medical (ELA, n = 12) 44 +/- 17 months, for Guidant (GDT, n = 36) 49 +/- 12 months, for Medtronic (MDT, n = 29) 62 +/- 22 months, and for St. Jude Medical (SJM, n = 5) 31 +/- 9 months (P < 0.001). SC ICD generators had a longer service time compared to DC and CRT-D systems. No influence of indication for ICD therapy and HO stimulation on generator longevity was observed in this study. MDT ICDs had the longest service time.

The primary aim of the study was to evaluate the efficacy of tumor necrosis factor (TNF)-α blockers adalimumab (ADA) and infliximab (IFX) in refractory sight-threatening retinal vasculitis (RV) during a 12-month follow-up period. Secondary aims were to evaluate (i) any impact of concomitant conventional disease-modifying anti-rheumatic drugs (cDMARDs) and different lines of biologic therapy; (ii) any difference in terms of efficacy between ADA and IFX; (iii) consequences of biotherapies on the best-corrected visual acuity (BCVA); (iv) corticosteroid-sparing effect; and (vi) ocular complications during anti-TNF-α treatment. Demographic, clinical, and therapeutic data were retrospectively collected from the medical records and statistically analyzed. Forty-eight patients (82 eyes) were recruited, 22 (45.8%) of which received IFX and 26 (54.2%) ADA. The percentages of patients achieving RV remission within 3 and 12 months were 54 and 86%, respectively. A significant decrease in RV detection was identified from baseline to 3-month (p < 0.0001) and 12-month (p < 0.0001) assessments and between 3-month and 12-month visits (p = 0.004). No differences were identified in terms of RV resolution between (i) patients undergoing monotherapy and those co-administered with cDMARDs at 3-month (p = 0.560) and 12-month (p = 0.611) follow-up; (ii) biologic-naïve patients and those already exposed to other biologics at 3-month (p = 0.497) and 12-month (p > 0.99) visits; and (iii) patients treated with ADA and those treated with IFX (p = 0.357). During the study period, a statistically significant corticosteroid-sparing effect was observed (p = 0.0002), while BCVA values did not significantly change (p = 0.950). Anti-TNF-α monoclonal antibodies have proved excellent results in patients with recalcitrant sight-threatening RV.

Human health hazards due to diesel exhaust (DE*) exposure have been associated with both solvent and combustion components. In the past, diesel engine exhaust components have been linked to increased mutagenicity in cultures of Salmonella typhimurium and mammalian cells (Tokiwa and Ohnishi 1986). In addition, DE has been shown to increase both the incidence of tumors and the induction of 8-hydroxy-deoxyguanosine adducts (8-OHdG) in ICR mice (Ichinose et al. 1997). Furthermore, DE is composed of a complex mixture of polycyclic aromatic hydrocarbons (PAHs) and particulates. One such PAH, 3-nitrobenzanthrone (3-NBA), has been identified in DE and found in urban air. 3-NBA has been observed to induce micronucleus formation in DNA of human hepatoma cells (Lamy et al. 2004). The purpose of the current research, which is part of the Advanced Collaborative Emissions Study (ACES), a multidisciplinary program being carried out by the Health Effects Institute and the Coordinating Research Council, is to determine whether improvements in the engineering of heavy-duty diesel engines reduce the oxidative stress and genotoxic risk associated with exposure to DE components. To this end, the genotoxicity and oxidative stress of DE from an improved diesel engine was evaluated in bioassays of tissues from Wistar Han rats and C57BL/6 mice exposed to DE. Genotoxicity was measured as strand breaks using an alkaline-modified comet assay. To correlate possible DNA damage found by the comet assay, measurement of DNA-adduct formation was evaluated by a competitive enzyme-linked immunosorbent assay (ELISA) to determine the levels of free 8-OHdG found in the serum of the animals exposed to DE. 8-OHdG is a specific modified base indicating an oxidative type of DNA damage to DNA nucleotides. In addition, a thiobarbituric acid reactive substances (TBARS) assay was used to assess oxidative stress and damage in the form of lipid peroxidation in the hippocampus region of the brains of DE-exposed animals. Results from the comet assay showed no significant differences in rats between the control and exposed groups (P = 0.53, low exposure; P = 0.92, medium exposure; P = 0.77, high exposure) after 1 month of DE exposure. There were no differences between sexes in the responses of rats to these exposures. Likewise, there were no significant differences found after 3 months of exposure. Similarly, no significant differences were found between the mice exposed for 1 and 3 months to DE, nor were any differences found between sexes. Measurements of 8-OHdG in both mice and rats showed no significant difference among DE exposure groups (P = 0.46, mice; P = 0.86, rats). In mice, measured 8-OHdG was lower in the 3-month group than the 1-month group. In rats, the inverse was true. In mice, no significant differences in the levels of lipid peroxidation, as measured by TBARS, were found between the controls and DE exposure groups (P = 0.92), nor were there any differences between sexes. In rats, comparisons between the control and low-exposure groups approached significance, but no significant differences were found between the other DE exposure groups. Additionally, in rats, there were no significant differences between the 1- and 3-month DE exposure groups.

The development of individual differences in behaviour in a novel environment, in the presence of a strange fish and during aggressive interactions with a mirror-image was studied in the lion-headed cichlid (Steatocranus casuarius, Teleostei, Cichlidae). No consistency in behaviour was found at 4-5.5 months of age. However, behaviours scored in situations involving a discrete source of stress (a strange fish or conspecific) become significantly consistent at the age of 12 months. At 4-5.5 but not 12 months of age, larger individuals approached and attacked the strange fish significantly more than smaller ones. These patterns may be associated with development and integration of motivational systems and alternative coping strategies.

Abstract Numerous studies document significant improvement in motor symptoms in patients with Parkinson's disease (PD) after deep brain stimulation of the subthalamic nucleus (STN-DBS). However, little is known about the initial effects of STN-DBS on nonmotor domains. Our objective was to elucidate the initial effects of STN-DBS on non-motor and motor symptoms in PD patients in a 4-month follow-up. This open prospective study followed 24 patients with PD who underwent STN-DBS. The patients were examined using dedicated rating scales preoperatively and at 1 and 4 months following STN-DBS to determine initial changes in motor and nonmotor symptoms. Patients at month 1 after STN-DBS had significantly reduced the Parkinson's disease Questionnaire scores (P = .018) and Scales for Outcomes in Parkinson's disease – Autonomic scores (P = .002); these scores had increased at Month 4 after DBS-STN. Nonmotor Symptoms Scale for Parkinson's Disease had improved significantly at Month 1 (P < .001); at Month 4, it remained significantly lower than before stimulation (P = .036). There was no significant difference in The Parkinson's Disease Sleep Scaleat Month 1 and significant improvement at Month 4 (P = .026). There were no significant changes in The Female Sexual Function Index or International Index of Erectile Function. Movement Disorder Society Unified Parkinson's Disease Rating Scale, Part III scores show significant improvements at Month 1 (P < .001) and at Month 4 (P < .001). STN-DBS in patients with advanced PD clearly improves not only motor symptoms, but also several domains of nonmotor functions, namely sleep, autonomic functions and quality of life quickly following the start of stimulation.

Background Home exercise can prevent falls in the general older community but its impact in people recently discharged from hospital is not known. The study aimed to investigate the effects of a home-based exercise program on falls and mobility among people recently discharged from hospital. Methods and Findings This randomised controlled trial (ACTRN12607000563460) was conducted among 340 older people. Intervention group participants (n = 171) were asked to exercise at home for 15–20 minutes up to 6 times weekly for 12 months. The control group (n = 169) received usual care. Primary outcomes were rate of falls (assessed over 12 months using monthly calendars), performance-based mobility (Lower Extremity Summary Performance Score, range 0–3, at baseline and 12 months, assessor unaware of group allocation) and self-reported ease of mobility task performance (range 0–40, assessed with 12 monthly questionaries). Participants had an average age of 81.2 years (SD 8.0) and 70% had fallen in the past year. Complete primary outcome data were obtained for at least 92% of randomised participants. Participants in the intervention group reported more falls than the control group (177 falls versus 123 falls) during the 12-month study period and this difference was statistically significant (incidence rate ratio 1.43, 95% CI 1.07 to 1.93, p = 0.017). At 12-months, performance-based mobility had improved significantly more in the intervention group than in the control group (between-group difference adjusted for baseline performance 0.13, 95% CI 0.04 to 0.21, p = 0.004). Self-reported ease in undertaking mobility tasks over the 12-month period was not significantly different between the groups (0.49, 95% CI −0.91 to 1.90, p = 0.488). Conclusions An individualised home exercise prescription significantly improved performance-based mobility but significantly increased the rate of falls in older people recently discharged from hospital.

Attention to the road is essential to safe driving, but the development of appropriate eye glance scanning behaviors may require substantial driving experience. Novice teen drivers may focus almost exclusively on the road ahead rather than scanning the mirrors, and when performing secondary tasks, they may spend more time with eyes on the task than on the road. This paper examines the extent to which the scanning of novice teens improves with experience. For this study, 18 novice teen (younger than 17.5 years old) and 18 experienced adult drivers performed a set of in-vehicle tasks and a baseline driving segment on a test track, the teens within 4 weeks of licensure and then again 6 months later. This paper addresses the following questions: Did teen eye glance performance improve from initial assessment? Did teens and adults still differ after 6 months? Results for some tasks showed that rearview and left mirror–window (LM-W) glances improved for teens from initial testing to the 6-month follow-up and that some differences between teens and adults at initial testing were no longer significant at the 6-month follow-up, suggesting significant learning effects. The frequency of rearview and LM-W glances during secondary tasks improved among teens at the 6-month follow-up, but teens still had significantly fewer glances to mirrors than did adults when engaged in a secondary task.

To examine the effectiveness of a "cardiopulmonary resuscitation song" in improving the basic life support skills of secondary school students. This pre-test/post-test control design study enrolled secondary school students from two middle schools randomly chosen in Córdoba, Andalucia, Spain. The study included 608 teenagers. A random sample of 87 students in the intervention group and 35 in the control group, aged 12-14 years were selected. The intervention included a cardiopulmonary resuscitation song and video. A questionnaire was conducted at three-time points: pre-intervention, one month and eight months post-intervention. On global knowledge of cardiopulmonary resuscitation, there were no significant differences between the intervention group and the control group in the trial pre-intervention and at the month post-intervention. However, at 8 months there were significant differences with a p-value = 0.000 (intervention group, 95% CI: 6.39 to 7.13 vs. control group, 95% CI: 4.75 to 5.92), F(1,120)=16.644, p=0.000). In addition, significant differences about students' basic life support knowledge about chest compressions at eight months post-intervention (F(1,120)=15.561, p=0.000) were found. Our study showed that incorporating the song component in the cardiopulmonary resuscitation teaching increased its effectiveness and the ability to remember the cardiopulmonary resuscitation algorithm. Our study highlights the need for different methods in the cardiopulmonary resuscitation teaching to facilitate knowledge retention and increase the number of positive outcomes after sudden cardiac arrest.

To evaluate the efficiency of social-cognitive theory-guided oral hygiene interventions in adolescents and to identify predictors of adolescents' self-care practice. A cluster randomized trial included 197 15- to 16-year-olds from two secondary schools. The intervention group received three face-to-face educational hands-on sessions facilitated by a dentist and adolescents worked in pairs. Individual dental plaque levels were measured at baseline, after intervention, at six and at 12 months. The structured questionnaire inquired about gender, family socio-economic status (baseline), and different social-cognitive domain variables (baseline, six, and 12 months). At baseline, there were no statistically significant differences in dental plaque scores between the intervention and control groups (P = 0.183). At the 6-month follow-up, the intervention group had significantly less dental plaque than the control group (P = 0.047), but the intergroup difference in dental plaque levels was not significant at the 12-month follow-up (P = 0.400). Variations in dental plaque levels at different time periods were explained by the following predictors: family's socio-economic status, social-cognitive domain variables, group affiliation, and baseline plaque levels. Social-cognitive theory-guided interventions improved oral self-care of adolescents in the short term. After the intervention was discontinued, the improvement in oral self-care of adolescents lasted for another 5 months. © 2015 BSPD, IAPD and John Wiley & Sons A/S.

A 1-year multicenter prospective randomized controlled study was conducted on the effects of vitamin E-bonded polysulfone dialyzers on erythropoiesis-stimulating agent response in hemodialysis patients. Major inclusion criteria were use of high-flux polysulfone dialyzers with 50-70 ml/min β2-microglobulin clearance over 3 months, transferrin saturation over 20%, same erythropoiesis-stimulating agent for over 3 months, and hemoglobin at 10-12 g/dl. Hemodialysis patients were placed in four interventional groups: two hemoglobin ranges (10.0-10.9 or 11.0-11.9 g/dl) and two dialyzers. Patients were randomly assigned by central registration to a vitamin E-bonded polysulfone dialyzers or polysulfone control group. Primary end point was relative erythropoiesis resistance index at baseline between groups at 12 months. Erythropoiesis resistance index was defined as total weekly erythropoiesis-stimulating agent dose divided by hemoglobin. There were no statistically significant differences in age or sex. There was no significant difference in relative erythropoiesis resistance index between vitamin E-bonded polysulfone dialyzers and control groups at 12 months (vitamin E-bonded polysulfone dialyzers: 1.1, control: 1.3). The vitamin E-bonded polysulfone dialyzers group showed better relative erythropoiesis resistance index than the control group at 11.0-11.9 g/dl hemoglobin (vitamin E-bonded polysulfone dialyzers: 1.0, control: 1.4 at 12 months, significant difference) but no difference at 10.0-10.9 g/dl hemoglobin. The overall relative erythropoiesis resistance index showed no difference between the vitamin E-bonded polysulfone dialyzers and control groups, although the change in relative erythropoiesis resistance index differed according to hemoglobin level.

Condors and vultures comprise the only group of terrestrial vertebrates in the world that are obligate scavengers, and these species move widely to locate ephemeral, unpredictable, and patchily-distributed food resources. In this study, we used high-resolution GPS location data to quantify monthly home range size of the critically endangered California Condor Gymnogyps californianus throughout the annual cycle in California. We assessed whether individual-level characteristics (age, sex and breeding status) and factors related to endangered species recovery program efforts (rearing method, release site) were linked to variation in monthly home range size. We found that monthly home range size varied across the annual cycle, with the largest monthly home ranges observed during late summer and early fall (July–October), a pattern that may be linked to seasonal changes in thermals that facilitate movement. Monthly home ranges of adults were significantly larger than those of immatures, but males and females used monthly home ranges of similar size throughout the year and breeding adults did not differ from non-breeding adults in their average monthly home range size. Individuals from each of three release sites differed significantly in the size of their monthly home ranges, and no differences in monthly home range size were detected between condors reared under captive conditions relative to those reared in the wild. Our study provides an important foundation for understanding the movement ecology of the California Condor and it highlights the importance of seasonal variation in space use for effective conservation planning for this critically endangered species.

To reveal the difference of meteorological effect on scarlet fever in Beijing and Hong Kong, China, during different periods among 2004-2014. The data of monthly incidence of scarlet fever and meteorological variables from 2004 to 2014 in Beijing and Hong Kong were collected from Chinese science data center of public health, meteorological data website and Hong Kong observatory website. The whole study period was separated into two periods by the outbreak year 2011 (Jan 2004-Dec 2010 and Jan 2011-Dec 2014). A generalized additive Poisson model was conducted to estimate the effect of meteorological variables on monthly incidence of scarlet fever during two periods in Beijing and Hong Kong, China. Incidence of scarlet fever in two districts were compared and found the average incidence during period of 2004-2010 were significantly different (Z=203.973, P<0.001) while average incidence became generally equal during 2011-2014 (Z=2.125, P>0.05). There was also significant difference in meteorological variables between Beijing and Hong Kong during whole study period, except air pressure (Z=0.165, P=0.869). After fitting GAM model, it could be found monthly mean temperature showed a negative effect (RR=0.962, 95%CI: 0.933, 0.992) on scarlet fever in Hong Kong during the period of 2004-2010. By comparison, for data in Beijing during the period of 2011-2014, the RRs of monthly mean temperature range growing 1°C and monthly sunshine duration growing 1h was equal to 1.196(1.022, 1.399) and 1.006(1.001, 1.012), respectively. The changes of meteorological effect on scarlet fever over time were not significant both in Beijing and Hong Kong. This study suggests that meteorological variables were important factors for incidence of scarlet fever during different period in Beijing and Hong Kong. It also support that some meteorological effects were opposite in different period although these differences might not completely statistically significant. Copyright © 2017 Elsevier B.V.

Abstract Background: The benefit of ≤6-month compared with 12-month dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) with drug-eluting stent (DES) placement remains controversial. We performed a meta-analysis and meta-regression of ≤6-month versus 12-month DAPT in patients undergoing PCI with DES placement. Methods: We conducted electronic database searches of randomized controlled trials (RCTs) comparing DAPT durations after DES placement. For studies with longer follow-up, outcomes at 12 months were identified. Odds ratios and 95% confidence intervals were computed with the Mantel–Haenszel method. Fixed-effect models were used; if heterogeneity (I2) > 40 was identified, effects were obtained with random models. Results: Nine RCTs were included with total n = 19,224 patients. No significant differences were observed between ≤6-month compared with 12-month DAPT in all-cause mortality (OR 0.87; 95% confidence interval (CI): 0.69–1.11), cardiovascular (CV) mortality (OR 0.89; 95% CI: 0.66–1.21), non-CV mortality (OR 0.85; 95% 0.58–1.24), myocardial infarction (OR 1.10; 95% CI: 0.89–1.37), stroke (OR 0.97; 95% CI: 0.67–1.42), stent thrombosis (ST) (OR 1.37; 95% CI: 0.89–2.10), and target vessel revascularization (OR 0.95; 95% CI: 0.77–1.18). No significant difference in major bleeding (OR 0.72; 95% CI: 0.49–1.05) was observed, though the all-bleeding event rate was significantly lower in the ≤6-month DAPT group (OR 0.76; 95% CI: 0.59–0.96). In the meta-regression analysis, a significant association between bleeding events and non-CV mortality with 12-month DAPT was found, as well as between ST and mortality in addition to MI with ≤6-month DAPT. Conclusion: DAPT for ≤6 months is associated with similar mortality and ischemic outcomes but less bleeding events compared with 12-month DAPT after PCI with DES. PMID:28033306

To assess the microbial effect of ozone gas on dentinal lesions in young permanent molars using the stepwise excavation. An experimental, controlled clinical trial was performed. The sample included 80 immature first permanent molars, showing deep occlusal carious cavities that were indicated for stepwise excavation. Following first step of dentin excavation, the sample was divided into test (ozone gas) and control (calcium hydroxide (Ca(OH) 2 ) base material) groups. One half of the cases in each group were evaluated for microbiological changes after 6 months, and the other half after 12 months. Mutans streptococci (MS), Lactobacilli, and Candida counts were significantly reduced immediately after ozone application in the test group (P ≤0.05). At the final assessment period, MS and Lactobacilli were significantly reduced in the test group (P ≤0.05). Meanwhile, the Candida counts were significantly reduced only in the test group of the 6 and 12 month-cases (P ≤0.05). Regarding the control group, the significant reduction in microbial count was observed with MS after 6 and 12 months (P ≤0.05). No significant differences were observed between test and control groups at different evaluation periods (P >0.05). Ozone gas had a significant antimicrobial effect in deep class I carious lesions.

Objectives. To evaluate alterations in sexual function and genital sensitivity after anastomotic repair (AR) and free graft urethroplasty (FGU) for bulbar urethral strictures. Methods. Patients treated with AR (n = 31) or FGU (n = 16) were prospectively evaluated before, 6 weeks and 6 months after urethroplasty. Evaluation included International Prostate Symptom Score (IPSS), 5-Item International Index of Erectile Function (IIEF-5), Ejaculation/Orgasm Score (EOS), and 3 questions on genital sensitivity. Results. At 6 weeks, there was a significant decline of IIEF-5 for AR (−4.8; p = 0.005), whereas there was no significant change for FGU (+0.9; p = 0.115). After 6 months, differences with baseline were not significant overall and among subgroups. At 6 weeks, there was a significant decline in EOS for AR (−1.4; p = 0.022). In the FGU group there was no significant change (+0.6; p = 0.12). Overall and among subgroups, EOS normalized at 6 months. After 6 weeks and 6 months, respectively, 62.2 and 52% of patients reported alterations in penile sensitivity with no significant differences among subgroups. Conclusions. AR is associated with a transient decline in erectile and ejaculatory function. This was not observed with FGU. Bulbar AR and FGU are likely to alter genital sensitivity. PMID:26494997

Higher fibre intakes are associated with risk reduction for chronic diseases. This study investigated the effects of supplementation with PolyGlycopleX® (PGX), a complexed polysaccharide, on insulin, glucose and lipids in overweight and obese individuals. In this double-blind 12 months study, participants were randomised into three groups: control (rice flour); PGX or psyllium (PSY). Participants followed their usual lifestyle and diet but consumed 5 g of their supplement before meals. Insulin was significantly lower in the PGX and PSY groups compared to control at 3 and 6 months and in the PSY group compared to control at 12 months. Serum glucose was significantly lower in the PGX group at 3 months compared to control. Total cholesterol was significantly lower in the PGX and PSY groups compared to control at 3 and 6 months. High density lipoprotein (HDL) cholesterol was significantly increased in the PGX group compared to control at 12 months. low density lipoprotein (LDL) cholesterol was significantly lower in the PGX group at 3 and 6 months compared to control and in the PSY group at 3 months compared to control. A simple strategy of fibre supplementation may offer an effective solution to glucose, insulin and lipid management without the need for other nutrient modification. PMID:28146065

The aim of this study was to investigate the long-term effect of acupuncture for treatment of tinnitus. This study is a randomized, patient- and assessor-blind, sham-acupuncture-controlled, pilot trial. Participants were adults (18-60 years old) with chronic (≥6 months), unilateral tinnitus, and without moderate or severe hearing loss. Thirty-three (33) participants were randomized to one of two treatment groups: real acupuncture and sham-acupuncture (nonmeridian; no specific response, de qi). Participants received 10 sessions of acupuncture treatment (twice a week for 5 weeks), and usual patient care education. The subjective outcome was the score of Tinnitus Handicap Inventory (THI) and Visual Analogue Scale (VAS) from baseline to 3 months after. Pure Tone Average (PTA) and Speech Discrimination (SD) from baseline to 3 months after were assessed as objective outcomes. A significant interaction between time and group in VAS (p=0.017) was evident, but not in THI, PTA, and SD scores. THI showed significant improvement at the end of treatment and 3 months after, compared to baseline, in real acupuncture (p=0.004). In SD, a significant long-term effect of real acupuncture was observed until 3 months after (p=0.011). However, the effect of real acupuncture in PTA was not maintained until 3 months after the end of treatment. No significant difference in the sham-acupuncture treatment group was evident. No statistical difference in any outcome was observed between real and sham acupuncture. Only in the mean percent change of VAS, real acupuncture showed statistical significance, compared with sham-acupuncture from baseline to 3 months after (p=0.019). Through evaluation of subjective (THI and VAS) and objective outcomes (PTA and SD), this study demonstrates the long-term effect of real acupuncture.

Importance Although research on quality of life and dermatologic conditions is well represented in the literature, information on teledermatology’s effect on quality of life is virtually absent. Objective To determine the effect of store and forward teledermatology on quality of life. Design Two-site, parallel-group, superiority randomized controlled trial. Setting Dermatology clinics and affiliated sites of primary care at 2 US Department of Veterans Affairs medical facilities. Participants Patients being referred to a dermatology clinic were randomly assigned, stratified by site, to teledermatology or the conventional consultation process. Among the 392 patients who met the inclusion criteria and were randomized, 326 completed the allocated intervention and were included in the analysis. Interventions Store and forward teledermatology (digital images and a standardized history) or conventional text-based consultation processes were used to manage the dermatology consultations. Patients were followed up for 9 months. Main Outcome Measures The primary end point was change in Skindex-16 scores, a skin-specific quality-of-life instrument, between baseline and 9 months. A secondary end point was change in Skindex-16 scores between baseline and 3 months. Results Patients in both randomization groups demonstrated a clinically significant improvement in Skindex-16 scores between baseline and 9 months with no significant difference by randomization group (P=.66, composite score). No significant difference in Skindex-16 scores by randomization group between baseline and 3 months was found (P=.39, composite score). Conclusions Compared with the conventional consultation process, store and forward teledermatology did not result in a statistically significant difference in skin-related quality of life at 3 or 9 months after referral.

Cognitive remediation therapy (CRT) is reported to improve neurocognitive and substance use disorder (SUD) outcomes in residential treatments. This National Institute of Drug Abuse funded pilot study reports on CRT as an augmentation to outpatient treatment for SUD. Recovering outpatient veterans were randomized into CRT + Work Therapy (n = 24) or work therapy (n = 24) with treatment-as-usual. Blind assessments of neurocognition and substance use were performed at baseline, 3 months (end of treatment), and 6-month follow-up. Baseline assessments revealed high rates of cognitive impairment with 87.5% showing significant decline from premorbid IQ on at least 1 measure (median = 3/14 measures). Adherence to treatment was excellent. Follow-up rates were 95.7% at 3 months and 87.5% at 6 months. Mixed effects models of cognitive change over time revealed significant differences favoring CRT + Work Therapy on working memory (WM) and executive function indices. Global index of cognition showed a nonsignificant trend (effect size [ES] = .37) favoring CRT + Work Therapy. SUD outcomes were excellent for both conditions. CRT + Work Therapy had a mean of 97% days of abstinence at 3 months, 94% in the 30 days prior to 6-month follow-up, and 24/26 weeks of total abstinence; differences between conditions were not significant. CRT was well accepted by outpatient veterans with SUDs and led to significant improvements in WM and executive functions beyond that of normal cognitive recovery. No difference between conditions was found for SUD outcomes, perhaps because work therapy obscured the benefits of CRT. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

To investigate the effect of treated clubfoot disorder on gross motor skill level measured by the Alberta Infant Motor Scale (AIMS). Fifty-two babies participated: 26 were treated for idiopathic clubfoot (12 with the Ponseti treatment method, 9 with the French physical therapy technique, and 5 with a combination of both methods); 26 were babies who were typically developing and without medical diagnoses. The AIMS was administered at 3-month intervals. No significant differences in AIMS scores were found between the clubfoot and control groups at 3 and 6 months, but at 9 and 12 months the clubfoot group scored significantly lower. Babies who were typically developing were significantly more likely to be walking at 12 months than babies with clubfoot. Treated clubfoot was associated with a mild delay in attainment of gross motor skills at 9 and 12 months of age.

The association of blood transfusions with graft survival after pediatric kidney transplant (KTx) is unclear. We retrospectively analyzed blood transfusions post-KTx and subsequent outcomes. Between 1984 and 2013, 482 children (<18 years of age) underwent KTx at our center. Recipient demographics, outcomes and transfusion data were collected. Cox regression with post-KTx blood transfusion as a time-dependent covariate was performed to model the impact of blood transfusion on outcomes. Of the 208 (44%) that were transfused, 39% had transfusion <1 month post-KTx; 48% > 12 months. Transfused and non-transfused recipients were not significantly different. In univariate and multivariate analyses, there was no difference between transfused and non-transfused recipient patient survival; antibody-mediated and acute cellular rejection, and donor-specific antibody (DSA) free survival. Transfusions <1 month post-KTx did not impact death-censored graft survival (DCGS) (p=NS). Patients transfused >12 months post-KTx had significantly lower 12 month estimated glomerular filtration rate (eGFR) (compared to non-transfused) and worse subsequent DCGS. Post-KTx blood transfusions have increased in pediatric KTx over time but have no negative association with rejection or DSA production. DCGS is unaffected by transfusion within first month. Transfusions after the first year occur in patients with more advanced chronic kidney disease and are associated with significantly worse DCGS. PMID:27712016

To investigate the effect on tear menisci after laser in situ keratomileusis (LASIK) with flap creation by either microkeratome or femtosecond laser. Sixty eyes of 30 myopes were analyzed. Fifteen patients underwent LASIK with Moria II microkeratome, and the other 15 patients with 60-KHz IntraLase femtosecond laser. Upper and lower tear meniscus parameters of height (UTMH, LTMH) and area (UTMA, LTMA) were measured by SD-OCT preoperatively and 1 week, 1 month, and 3 months postoperatively. Compared with the baseline values, all tear meniscus parameters decreased significantly at each postoperative time point (all P < 0.01) in both groups. LTMH increased significantly between 1 week and 1 month and between 1 and 3 months after surgery in the microkeratome (both P < 0.01) and femtosecond laser groups (P < 0.01, P = 0.012, respectively). There were significant increases in LTMA between 1 week and 1 month after surgery in the microkeratome group (P < 0.01) and in the femtosecond laser group (P = 0.028). There were no significant differences in UTMH, UTMA, LTMH, or LTMA between two groups. The depth of ablation was negatively correlated with the LTMA at 1 week after surgery (R = -0.256, P = 0.049) for all patients. There were no significant differences in the tear meniscus parameters between the microkeratome and femtosecond laser groups. The depth of ablation was significantly correlated with the LTMA only at 1 week after surgery. Copyright 2014 The Association for Research in Vision and Ophthalmology, Inc.

Hair cycle activity has been extensively studied in humans, sheep and laboratory animals, but there is a lack of information in dogs. Besides varying according to species, breed, sex and general health, hair growth is mainly affected by climatic variations. The aim of the study was to evaluate the follicle activity in three breeds of dogs with different hair types, in the city of Viçosa, Minas Gerais (latitude 20 degrees 45'S), Brazil. Twenty-one male dogs of boxer, labrador and schnauzer breeds were trichographically analysed monthly over 12 consecutive months. Hair percentage of telogen and anagen hairs at the different stages of the hair cycle in boxers and labradors was not significantly different, but both differed from the schnauzers. A significant correlation between hair follicle cycle and environmental temperature and photoperiod was noted in the boxers and labradors. In these breeds, a larger number of telogen hairs were observed during the hottest months of the year, and an increase in anagen hairs during the coldest months. The mean percentage of telogen hairs was 93, 90 and 55.3% for boxer, labrador and schnauzer, respectively.

There is clear evidence that environmental factors play an important role regarding physical activity (PA) and sedentary behaviour (SB) in youth. This short report highlights seasonal differences in the amount and intensities of PA and SB, in Portuguese youth. Three hundred and eighty-seven participants (aged 14.7 ± 1.9 years), 220 girls, used the Actigraph GT1M accelerometer for 7 days (15-second epochs), between January and June in 2008. PA and SB differences were assessed using an ANCOVA. Boys had significantly higher values of PA, with the exception of Light intensity. Girls were significantly more sedentary. PA intensities and SB changed significantly according to gender and month of assessment. SB (Gender F = 16.32, p < 0.001; Month F = 2.95, p < 0.013), Light PA (Gender F = 9.30, p = 0.002; Month F = 8.37, p < 0.001; Gender*Month F = 2.24, p = 0.050), Moderate PA (Gender F = 40.04, p < 0.001), Vigorous PA (Gender F = 32.89, p < 0.001; Month F = 2.56, p = 0.027). Both genders increased PA from winter to summer months and SB decreased. Seasonality in PA intensities and SB suggest that interventions to promote PA and decrease SB must be tailored to take into consideration the month of the year they are going to be implemented and also gender characteristics.

To explore the growth pattern of appropriate for gestational age (AGA) infants of mother with gestational diabetes mellitus (GDM). The objects of this study were offspring of women who delivered in our hospital from January to December 2011. The GDM group included 70 AGA infants (36 male cases and 34 female cases) of mother with GDM. The control group included 154 AGA infants (66 male cases and 88 female cases) of women with normal glucose tolerance. The data of demographic characteristics of mothers of two groups were collected. Body weight and length of infants in two groups were measured at 3, 6 and 12 months age respectively. Body mass index (BMI), weight and height gain during infancy (0-3 months, 3-6 months and 6-12 months) of infants in two groups were also calculated. Body weight, length and BMI of male AGA infants in GDM group were less than that of control group at 3 months and 6 months age, but more than that of control group at 12 months age, however, there were no significant differences between two group(P>0.05). The weight and height gain during infancy (0-3 months, 3-6 months) of male AGA infants in GDM group were lower than that of control group, but the difference was statistically significant only at 3-6 months[(1.1±0.4) vs (1.4±0.4) kg, P=0.040; (4.9±2.3) vs (6.3±1.2) cm, P=0.026]. The weight and height gain during infancy (6-12 months) of male AGA infants of gestational diabetic mothers were higher than that of control group, but the difference was not statistically significant[(2.1±0.5) vs (1.8±0.5) kg, P=0.361; (8.4±1.3) vs (7.8±1.4) cm, P=0.464]. Male infants of gestational diabetic mothers grew slowly during their infancy of 0-6 months, and then their growth became increasingly fast, which suggested that the influence of intrauterine hyperglycemia environment of GDM mothers on fetal growth might continue after birth.

Objective: Tailor-made notched music was applied to alleviate the symptoms of chronic idiopathic tinnitus and compared its effectiveness with other existing sound treatment of tinnitus. Methods: Subjects ( n =43; ears=75 )were recruited during June 2015 to October 2016 from the out-patients of our hospital. These patients had chronic (longer than 6months) and idiopathic tinnitus, with or without significant sensorineural hearing loss. In the prospective design, the patients were randomly divided into group A (treated with tailor-made notched music) and group B (treated with analogous sound masking), and received the treatment for 3 months. The tinnitus scale, tinnitus questionnaire and audiological findings were evaluated before treatment, and at one month and three months after treatment started. Results: After onemonth of treatment, the effective rate between the two groups was 40.9% and 42.9%, there was no significant difference between the two groups (χ(2)= 0.017, P =0.897). The average VAS for patients in group A showed more decrease in group A than in group B(VAS: 1.8 vs . 0.8, the percentage : 29.5% vs . 13.6%), but there was no significant difference between the two groups ( t =-1.450, P =0.155). After 3 months of treatment, the effective rates were 68.2% and 23.8%, respectively. There was significant difference between the two groups (χ(2)= 8.503, P =0.004). The difference of the VAS scores between the two groups was statistically significant ( t =-3.263, P =0.002), and the VAS score of group A was less.After 3 months of treatment, there was significant decreaseinthe average tinnitus loudness for patients in group A( t =5.569, P <0.01), and there was no significant changein group B( t =-0.953, P =0.374). There was also significant decreasein the scores of tinnitus handicap inventory (THI) ( F =7.334, P <0.05), loudness visual analog scale (VAS) ( F =20.48, P <0.001), and the proportion of patients with moderate to severe tinnitus(χ(2)=11.289, P <0.05) in the group A, and there was no significant change in group B( F =2.198, F =0.989, χ(2)=1.651; P =0.120, P =0.378, P =0.438>0.05). Conclusions: Our resultssuggest that long-term normalized listening to tailor-made notched music, can significantly reduce the perceived tinnitus loudness in varying degrees and improve the quality of life of patients. The effects and possible mechanism of this method were discussedin this paper.

Loss of bone mineral mass, muscle atrophy, and functional limitations are predictable consequences of immobilization and subsequent weight-bearing restriction due to leg or ankle fractures. The aim of this study was to prospectively determine whether decreased bone mineral mass following lower-limb fractures recovers at follow-up durations of six and eighteen months in adolescents. In the present study, we included fifty adolescents who underwent cast immobilization for a leg or ankle fracture. Dual x-ray absorptiometry scans of four different sites (total hip, femoral neck, entire lower limb, and calcaneus) were performed at the time of the fracture, at cast removal, and at follow-ups of six and eighteen months. Patients with fractures were paired with healthy controls according to sex, age, and ethnicity. Dual x-ray absorptiometry values were compared between groups and between injured and non-injured legs in adolescents with fractures. Among those with fractures, lower-limb bone mineral variables were significantly lower at the injured side compared with the non-injured side at cast removal, with differences ranging from 6.2% to 31.7% (p < 0.0001). Similarly, injured adolescents had significantly lower bone mineral values at the level of the injured lower limb compared with healthy controls (p < 0.0001). At the six-month follow-up, there were still significant residual differences between injured and non-injured legs in adolescents with fractures (p < 0.0001). However, a significant residual difference between healthy controls and injured adolescents was present only for femoral neck bone mineral density (p = 0.011). At the eighteen-month follow-up, no significant difference was observed at any lower-limb site. Bone mineral loss following a fracture of the lower limb in adolescents is highly significant and affects the lower limb both proximal to and distal to the fracture site. In contrast to observations in adults, a rapid bone mass reversal occurs with full bone recovery by eighteen months. Prognostic Level I.

Osteochondral autografts and allografts have been widely used in the treatment of isolated grade 4 articular cartilage lesions of the knee. However, there is a paucity of literature regarding the basic science investigating the direct comparison between fresh osteochondral allografts to autografts. At 12 months, fresh osteochondral allografts are equal to autografts with respect to function, bony incorporation into host bone, and chondrocyte viability. Controlled laboratory study. Eight adult mongrel dogs underwent bilateral hindlimb osteochondral graft implantation in the knee after creation of an acute Outerbridge grade 4 cartilage defect. One hindlimb of each dog knee received an autograft, and the contralateral knee received an allograft. All dogs were sacrificed at 12 months. Graft analysis included gross examination, radiographs, magnetic resonance imaging (MRI), biomechanical testing, and histology. MRI demonstrated excellent bony incorporation of both autografts and allografts, except for 1 allograft that revealed partial incorporation. Histologic examination of cartilage showed intact hyaline appearance for both autografts and allografts, with fibrocartilage at the host-graft interface of both. Biomechanical testing demonstrated no significant difference between allografts and autografts (P = .76). Furthermore, no significant difference was observed between allografts and the native cartilage with biomechanical testing (P = .84). After 12 months from time of implantation, fresh osteochondral allograft tissue and autograft tissue in this study were not statistically different with respect to biomechanical properties, gross morphology, bony incorporation, or overall histologic characteristics. When compared with the previously reported 6-month incorporation rates, there was improved allograft and autograft incorporation at 12 months. With no significant differences in gross examination, radiographs, MRI, biomechanical testing, or histology in the canine model, the use of allograft tissue to treat osteochondral defects may eliminate the morbidity associated with autograft harvest. © 2016 The Author(s).

To determine whether there were ocular surface changes in glaucomatous patients treated with preservatives beta-blockers who switched to preservative-free beta-blockers. This was a prospective, longitudinal, open-labeled study. One hundred thirty-two patients with primary open angle glaucoma treated with a preserved beta-blocker were enrolled. All the patients underwent perimetric and gonioscopic examination, complete ophthalmologic examination, intraocular pressure (IOP) measurements, evaluation of ocular surface, Schirmer's test, blood pressure and heart rate at baseline and 1-3 months after changing the medical treatment to a preservative-free timolol 0.1% (Timogel 0.1; Thea). At baseline, after 1 month and at the end of the study (3 months), all patients underwent a questionnaire on the visual quality and symptoms and on the quality of life (QoL). Data were analyzed by t-test when the distribution of the data was normal, by Mann-Whitney when the distribution was not normal. No significant difference was found for IOP before switching from preserved beta-blockers to preservative-free ones. No significant difference was found in blood pressure and heart rate. However, a statistically significant difference was found for abnormal fluorescein staining of the cornea and conjunctiva, eyelid erythema, conjunctival hyperemia, and follicular hyperplasia. A significant difference was found for break-up time (from 9.38±4.7 s at baseline to 10.64±4.7 s after 3 months) and Schirmer's test (from 12.9±5.96 mm at baseline to 14.2±5.87 mm after 3 months). The questionnaire showed that the patient improved the dryness and foreign body sensation. In glaucomatous patients, preservative-free 0.1 timolol treatment improved their QoL. Similar dry eye signs or symptoms improved after 3 months of treatment reducing dryness, hyperemia, follicular hyperplasia, and foreign body sensation.

Acute severe steroid-refractory ulcerative colitis (UC) carries a poor prognosis and requires optimal management. A systematic review and meta-analysis were conducted to assess cyclosporine and infliximab (IFX) as rescue agents in patients with steroid-refractory UC. A literature search identified studies that investigated IFX and cyclosporine in steroid-refractory UC patients. The primary outcome was short-term response to treatment. Secondary outcomes included the rates of colectomy at 3 months and 12 months, adverse drug reactions, post-operative complications in those who received rescue therapy but underwent colectomy subsequently, and mortality. Odds ratios (ORs) with 95% confidence intervals (CIs) are reported. Overall, 16 studies with 1,473 participants were eligible for inclusion. Among three randomized controlled trials, no significant difference was seen with IFX compared with cyclosporine with regard to treatment response and 3- or 12-month colectomy. Among 13 non-randomized studies, IFX was associated with significantly higher rates of treatment response (OR 2.96 (95% CI 2.12-4.14, χ(2)=6.50, I(2)=0%)) and a lower 12-month colectomy rate (OR 0.42 (95% CI 0.22-0.83, χ(2)=30.94, I(2)=71%)), with no significant difference seen in the 3-month colectomy rate (OR 0.53 (95% CI 0.22-1.28, χ(2)=22.73, I(2)=69%)) compared with cyclosporine. There were no significant differences between IFX and cyclosporine in adverse drug-related events, post-operative complications, or mortality. In the management of steroid-refractory severe UC, no definitive difference between IFX and cyclosporine is demonstrated by randomized trials, but non-randomized studies suggest that IFX is associated with better treatment response and lower risk of colectomy at 12 months. Prospective studies comparing dose-optimized IFX with cyclosporine are needed.

We evaluated the significance of head circumference growth velocity as related to developmental deficits during infancy. Head circumferences, lengths, and developmental diagnoses were retrieved in a standard manner at ≥ 2 time points from 437 infants with developmental deficits, and 3909 normally developing infants. Infants' ages ranged from 1-24 months, with final diagnoses ascertained at age 24 months. Increased velocity during the first 2 months in typical infants was evident in the study group during the period 2-4 months. A differential head circumference growth velocity was observed, and infants diagnosed with motor delay presented decreased velocity between ages 2-4 months, compared with infants receiving other nonmotor developmental diagnoses. These differences remained after controlling for birth weight and length. No significant sex effect was evident. Infants with developmental deficits demonstrate delayed acceleration of head circumference velocity, compared with typical infants in the first 2 months. Infants with motor delay manifest decreased velocity, compared with infants presenting other developmental deficits. These differences may be related to delayed white matter maturation.

To compare the efficacy and safety of the European labels of ranibizumab 0.5 mg vs dexamethasone 0.7 mg in patients with macular edema secondary to central retinal vein occlusion (CRVO). Phase IIIb, multicenter, double-masked, randomized clinical trial. Patients were randomized (1:1) to receive either monthly ranibizumab followed by pro re nata (PRN) treatment (n = 124) or 1 sustained-release dexamethasone implant followed by PRN sham injections (n = 119). Main outcomes were mean average change in best-corrected visual acuity (BCVA) from baseline to month 1 through month 6, mean change in BCVA, and adverse events (AEs). Of 243 patients, 185 (76.1%) completed the study. No difference was observed in BCVA between ranibizumab and dexamethasone at months 1 and 2. From month 3 to month 6, there was significant difference in BCVA gains in favor of ranibizumab. At month 6, mean average BCVA gain was significantly higher with ranibizumab than with dexamethasone (12.86 vs 2.96 letters; difference 9.91 letters, 95% confidence interval [6.51-13.30]; P < .0001). Mean injection number of ranibizumab was 4.52. Ocular AEs were reported in more patients in the dexamethasone than in the ranibizumab group (86.6% vs 55.6%). Using the European labels, similar efficacy was observed for ranibizumab and dexamethasone at months 1 and 2. However, ranibizumab maintained its efficacy throughout the study, whereas dexamethasone declined from month 3 onward. The main limitation of the study was that dexamethasone patients received only a single treatment during the 6-month study. In clinical practice, dexamethasone retreatment may be required earlier than 6 months. Safety findings were similar to those previously reported. Copyright © 2016 Elsevier Inc. All rights reserved.

The purpose of this study was to evaluate the effect of sports and energy drinks on the surface hardness of different restorative materials over a 6-month period. Forty-two disk-shaped specimens were prepared for each of the four restorative materials tested: Compoglass F, Filtek Z250, Filtek Supreme, and Premise. Specimens were immersed for 2 min daily, up to 6 months, in six storage solutions (n=7 per material for each solution): distilled water, Powerade, Gatorade, X-IR, Burn, and Red Bull. Surface hardness was measured at baseline, after 1 week, 1 month, and 6 months. Data were analyzed statistically using repeated measures ANOVA followed by the Bonferroni test for multiple comparisons (α=0.05). Surface hardness of the restorative materials was significantly affected by both immersion solution and immersion period (p<0.001). All tested solutions induced significant reduction in surface hardness of the restorative materials over a 6-month immersion period.

To study the effect of aluminume adjuvant and immunization schedule on immunogenicity of Sabin inactivated poliovirus vaccine. Four batches of Sabin IPV were produced by different concentrations of type 1, 2, and 3 poliovirus and administrated on three-dose schedule at 0, 1, 2 months and 0, 2, 4 months on rats. Serum samples were collected one month after each dose and neutralizing antibody titers against three types poliovirus were determined by micro-neutralization assay. The GMTs of neutralizing antibodies against three types poliovirus increased significantly and the seropositivity rates were 100% in all groups after 3 doses. There was no significant difference between two immunization schedules, and the 0, 2, 4 month schedule could induce higher level neutralizing antibody compared to the 0, 1, 2 month schedule. The groups with aluminum adjuvant could induce higher level neutralizing antibody compared to the groups without adjuvant. Aluminum djuvant and immunization schedule could improve the immunogenicity of Sabin IPV.

To compare the surgical outcomes of simultaneous penetrating keratoplasty and cataract surgery with those of sequential surgery. Thirty-nine eyes of 39 patients scheduled for simultaneous keratoplasty and cataract surgery and 23 eyes of 23 patients scheduled for sequential keratoplasty and secondary phacoemulsification surgery were recruited. Refractive error, regular and irregular corneal astigmatism determined by Fourier analysis, and endothelial cell loss were studied at 1 week and 3, 6, and 12 months after combined surgery in the simultaneous surgery group or after subsequent phacoemulsification surgery in the sequential surgery group. At 3 and more months after surgery, mean refractive error was significantly greater in the simultaneous surgery group than in the sequential surgery group, although no difference was seen at 1 week. The refractive error at 12 months was within 2 D of that targeted in 15 eyes (39%) in the simultaneous surgery group and within 2 D in 16 eyes (70%) in the sequential surgery group; the incidence was significantly greater in the sequential group (P = 0.0344). The regular and irregular astigmatism was not significantly different between the groups at 3 and more months after surgery. No significant difference was also found in the percentage of endothelial cell loss between the groups. Although corneal astigmatism and endothelial cell loss were not different, refractive error from target refraction was greater after simultaneous keratoplasty and cataract surgery than after sequential surgery, indicating a better outcome after sequential surgery than after simultaneous surgery.

Teachers' self-efficacy and development may be conceptualized as their beliefs in their own ability to plan, organize and carry out activities that are required to attain educational goals. In this study, we examined the effect of different medical education training courses (six-day, one- month short- term and sixmonth long- term courses) on perceived self-efficacy and development. This before-after quasi-experimental study was performed on 39 faculty members of Tehran University of Medical Sciences who participated in faculty development courses in 2013. We used valid and reliable scales to measure their perceived self-efficacy and empowerment. The results revealed a significant increase in faculty members' perceived self-efficacy in pre and posttests in one-month and six-month courses, but no significant difference was found in the six-day course (p=0.004, p<0.001 and p=0.235, respectively). These results were the same for perceived empowerment (p<0.001, p<0.001 and p=0.716 for one-month, six-month and six-day courses, respectively). A significant difference was detected in perceived self-efficacy and participant empowerment components based on the training course (p=0.005; Wilk's Λ=0.345, Partial η2=0.413). This study revealed that long- term courses were more effective than the short- term ones. Thus, longitudinal courses are recommended for more effectiveness.

This study investigated the reproducibility of repeated measurements with the Kikuhime pressure sensor under two different types of pressure garments used in the treatment and prevention of scars after burns. Also efficiency of garments was assessed in clinical circumstances by assessing pressure loss and residual pressure after 1 month. Intra- and inter-observer reproducibility and repeated measurements with 1-month time lapse were examined on 55 sites in 26 subjects by means of intra-class correlation coefficients and standard error of measurements. Results showed good to excellent ICC and low SEMs in the two conditions. There was a significant difference in pressure after 1 month between elastic tricot and weft knit garments, although evolution of pressure loss after 1 month was similar. Concerning different locations, there was a significant difference in pressure loss after 1 month between gloves and sleeves with the largest pressure loss for sleeves. Considering these results we concluded that the Kikuhime pressure sensor provides valid and reliable information and can be used in comparative clinical trials to evaluate pressure garments used in burn scar treatment. Secondly, elastic tricot garments in our study tended to have higher clinical pressures but both types of garments had similar pressure loss over time.

To summarize the application and experience of repairing spontaneous Achilles tendon rupture by part-Kessler technique with suture anchor. Between January 2011 and December 2013, 31 patients with spontaneous Achilles tendon rupture were treated by part-Kessler technique with suture anchor. Of 31 cases, 23 were male and 8 were female, aged 16-53 years (mean, 38 years). The left side was involved in 15 cases and the right side in 16 cases. The causes of injury included sudden heel pain and walking weakness during sports in 22 cases; no surefooted down-stairs, slip, and carrying heavy loads in 9 cases. The distance from broken site to the calcaneus adhension of Achilles tendon was 3-6 cm (mean, 4.2 cm). The time from injury to operation was 7 hours to 4 days (mean, 36.8 hours). All incisions healed by first intention without nerve injury or adhering with skin. The patients were followed up 6-24 months (mean, 15 months). All patients could complete 25 times heel raising without difficulty at 6 months after operation. No Achilles tendon rupture occurred again during follow-up. At 6 months after operation, the range of motion of the ankle joint in dorsiflexion and plantar flexion showed no significant difference between normal and affected sides (t=0.648, P=0.525; t=0.524, P=0.605). The circumference of the affected leg was significantly smaller than that of normal leg at 6 months after operation (t=2.074, P=0.041), but no significant difference was found between affected and normal sides at 12 months after operation (t=0.905, P=0.426). The American Orthopedic Foot and Ankle Society (AOFAS) scores at 6, 12, 18, and 24 months after operation were significantly higher than preoperative score (P<0.05); the score at 6 months after operation was significantly lower than that at other time points (P<0.05), but no significant difference was shown between the other time points (P>0.05). Repairing spontaneous Achilles tendon rupture by part-Kessler technique with suture anchor can supply strong strain and decrease the shear forces of suture. So part-Kessler technique with suture anchor is successful in repairing spontaneous Achilles tendon rupture.

Background We evaluate the effectiveness of a physical activity promotion programme carried out by general practitioners with inactive patients in routine care. Methods and Findings Pragmatic, cluster randomised clinical trial conducted in eleven public primary care centres in Spain. Fifty-six general practitioners (GPs) were randomly assigned to intervention (29) or standard care (27) groups. They assessed the physical activity level of a systematic sample of patients in routine practice and recruited 4317 individuals (2248 intervention and 2069 control) who did not meet minimum physical activity recommendations. Intervention GPs provided advice to all patients and a physical activity prescription to the subgroup attending an additional appointment (30%). A third of these prescriptions were opportunistically repeated. Control GPs provided standard care. Primary outcome measure was the change in self-reported physical activity from baseline to six, 12 and 24 months. Secondary outcomes included cardiorespiratory fitness and health-related quality of life. A total of 3691 patients (85%) were included in the longitudinal analysis and overall trends over the whole 24 month follow-up were significantly better in the intervention group (p<0.01). The greatest differences with the control group were observed at six months (adjusted difference 1.7 MET*hr/wk [95% CI, 0.8 to 2.6], 25 min/wk [95% CI, 11.3 to 38.4], and a 5.3% higher percentage of patients meeting minimum recommendations [95% CI: 2.1% to 8.8%] NNT = 19). These differences were not statistically significant at 12 and 24 months. No differences were found in secondary outcomes. A significant difference was maintained until 24 months in the proportion of patients achieving minimum recommendation in the subgroup that received a repeat prescription (adjusted difference 10.2%, 95% CI 1.5% to 19.4%). Conclusions General practitioners are effective at increasing the level of physical activity among their inactive patients during the initial six-months of an intervention but this effect wears off at 12 and 24 months. Only in the subgroup of patients receiving repeat prescriptions of physical activity is the effect maintained in long-term. Trial Registration clinicaltrials.gov NCT00131079 PMID:21479243

The purpose of this study is to compare the retropubic tension-free vaginal tape (TVT) procedure with the inside-out transobturator approach (TVT-O). Multicenter randomized controlled trial. One hundred forty-nine patients were randomly allocated to either TVT (n = 75) or TVT-O (n = 74). Interview, medical examination, pain scores, success rates, and quality of life assessment were recorded pre-operatively, and 2, 6, 12, and 24 months post-operatively. One hundred forty-nine patients underwent surgery, and 132 completed a 24-month follow-up. Bladder injury rate was 5% (4/75) in the TVT group and 2% (2/74) in the TVT-O group (p = 0.68). There was no significant difference between the two groups, concerning overall cure rate and the patients' satisfaction rate at 24 months follow-up. The range of mean pain scores was significantly higher after the TVT-O procedure post-operatively but not at 24 months follow-up. TVT and TVT-O procedures both have an outcome associated with an increase in quality of life with no significant differences in satisfaction rates at 2 years follow-up.

The purpose of the study was to investigate the content of nickel (Ni) ion in patients' saliva after wearing the porcelain-fused-to nickel-chromium (Ni-Cr) crown or the porcelain-fused-to nickel-chromium-titanium(Ni-Cr-Ti) crown. 50 patients who had one molar or premolar needed repairing were selected and divided into two groups randomly. Patients in one group were fabricated with porcelain-fused-to Ni-Cr crown and the patients in the other group were fabricated with porcelain-fused-to Ni-Cr-Ti crown. Collect the patients' saliva before wearing, 1 week, 3 months, and 6 months after wearing. The content of Ni ion in saliva was detected by inductively coupled plasma mass spectrometry (ICP-MS). The content of Ni ion in both groups increased at the first week, and go back after 6 months. There were no significant differences before wearing, 1 week, 3 months, and 6 months after wearing. There were no significant differences between the two groups. Wearing the porcelain-fused-to Ni-Cr crown or the porcelain-fused-to Ni-Cr-Ti crown has no significant influence on the content of Ni ion in saliva.

Vanadium is a transitional metal with an ability to generate reactive oxygen species in the biological system. This work was designed to assess memory deficits in mice chronically exposed to vanadium. A total of 132 male BALB/c mice (4 weeks old) were used for the experiment and were divided into three major groups of vanadium treated, matched controls, and animals exposed to vanadium for three months and thereafter vanadium was withdrawn. Animals were tested using Morris water maze and forelimb grip test at 3, 6, 9, and 12 months of age. The results showed that animals across the groups showed no difference in learning but had significant loss in memory abilities after 3 months of vanadium exposure and this trend continued in all vanadium-exposed groups relative to the controls. Animals exposed to vanadium for three months recovered significantly only 9 months after vanadium withdrawal. There was no significant difference in latency to fall in the forelimb grip test between vanadium-exposed groups and the controls in all age groups. In conclusion, we have shown that chronic administration of vanadium in mice leads to memory deficit which is reversible but only after a long period of vanadium withdrawal. PMID:26962395

Implantation of an inflatable penile prosthesis (IPP) is a well-established definitive solution for erectile dysfunction when conservative treatments fail. Penile implants may shorten the penis. The AMS 700 LGX IPP is in common use but reports on its mechanical reliability, medium-term postsurgical patient satisfaction, and mean penile length preservation are lacking. We investigate the mean penile length, mechanical reliability, and patient satisfaction at 6 and 12 months after implantation of the AMS 700 LGX. This prospective study consecutively enrolled men undergoing first-time IPP implant surgery from February 2009 to April 2012. Stretched flaccid penile length, penile length at 50% and 100% of stiffness (P50 and P100) and International Index of Erectile Function (IIEF) and Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) scores, were measured at 6 and 12 months postsurgery. Of 45 patients who underwent AMS 700 LGX implantation (median age 61 years) and completed 6 months’ follow-up, 36 (80%) completed the study. A significant difference in stretched flaccid penile length was seen between 6 and 12 months (P = 0.033). P100 was also significantly increased at 6 and 12 months, with a mean 10% increase (1.3 ± 0.4 cm) from baseline to 12 months. Differences in mean IIEF scores at 6 and 12 months were significant for the desired domain (P = 0.0001) and for overall satisfaction (P = 0.002); however, mean EDITS scores at 6 and 12 months were not significantly improved. AMS 700 LGX is a powerful tool for preserving penile length in men undergoing penile prosthesis implantation. PMID:26112480

Stroke results in varying levels of physical disabilities that may adversely impact balance with increased tendency to falls. This may intensify with cognitive impairments (CI), and impede functional recovery. Therefore, task-specific balance training (TSBT), which presents versatile task-specific training options that matches varied individual needs, was explored as a beneficial rehabilitation regime for stroke survivors with and without CI. It was hypothesized that there will be no significant difference in the balance control measures in stroke survivors with and without CI after a 12-month TSBT. To determine if TSBT will have comparable beneficial effects on the balance control status of sub-acute ischemic stroke survivors with CI and without CI. One hundred of 143 available sub-acute first ever ischemic stroke survivors were recruited using convenience sampling technique in a quasi-experimental study. They were later assigned into the cognitive impaired group (CIG) and non-cognitive impaired group (NCIG), respectively, based on the baseline presence or absence of CI, after screening with the mini-mental examination (MMSE) tool. With the help of four trained research assistants, TSBT was applied to each group, thrice times a week, 60 mins per session, for 12 months. Their balance was measured as Bergs Balance scores (BBS) at baseline, 4th, 8th, and 12th month intervals. Data were analyzed statistically using Kruskal Wallis test, and repeated measure ANOVA, at p < 0.05.  There was significant improvement across time points in the balance control of CIG with large effect size of 0.69 after 12 months of TSBT. There was also significant improvement across time points in the balance control of NCIG with large effect size of 0.544 after 12 months of TSBT. There was no significant difference between the improvement in CIG and NCIG after 8th and 12th months of TSBT.  Within the groups, a 12-month TSBT intervention significantly improved balance control, respectively, but with broader effects in the CIG than NCIG. Importantly, though between-group comparison at baseline revealed significantly impaired balance control in the CIG than NCIG, these differences were not significant at the 8th month and non-existent at the 12th month of TSBT intervention. These results underscore the robustness of TSBT to evenly address specific balance deficits of stroke survivors with and without CI within a long-term rehabilitation plan as was hypothesized.

The Idiopathic Intracranial Hypertension Treatment Trial (IIHTT) showed that acetazolamide provided a modest, significant improvement in mean deviation (MD). Here, we further analyze visual field changes over the 6-month study period. Of 165 subjects with mild visual loss in the IIHTT, 125 had perimetry at baseline and 6 months. We evaluated pointwise linear regression of visual sensitivity versus time to classify test locations in the worst MD (study) eye as improving or not; pointwise changes from baseline to month 6 in decibels; and clinical consensus of change from baseline to 6 months. The average study eye had 36 of 52 test locations with improving sensitivity over 6 months using pointwise linear regression, but differences between the acetazolamide and placebo groups were not significant. Pointwise results mostly improved in both treatment groups with the magnitude of the mean change within groups greatest and statistically significant around the blind spot and the nasal area, especially in the acetazolamide group. The consensus classification of visual field change from baseline to 6 months in the study eye yielded percentages (acetazolamide, placebo) of 7.2% and 17.5% worse, 35.1% and 31.7% with no change, and 56.1% and 50.8% improved; group differences were not statistically significant. In the IIHTT, compared to the placebo group, the acetazolamide group had a significant pointwise improvement in visual field function, particularly in the nasal and pericecal areas; the latter is likely due to reduction in blind spot size related to improvement in papilledema.

Scintigraphy has been used as a tool to detect dysfunction of the lung before and after transplantation. The aims of this study were to evaluate the development of the ventilation-perfusion relationships in single lung transplant recipients in the first year, at 3 months after transplantation, and to investigate whether scintigraphic findings at 3 months were predictive for the outcome at 12 months in relation to primary graft dysfunction (PGD) and lung function. A retrospective study was carried out on all patients who prospectively and consecutively were referred for a routine lung scintigraphy procedure 3 months after single lung transplantation (SLTX). A total of 41 patients were included in the study: 20 women and 21 men with the age span of patients at transplantation being 38-66 years (mean ± SD: 54.2 ± 6.0). Patient records also included lung function tests and chest X-ray images. We found no significant correlation between lung function distribution at 3 months and PGD at 72 h. There was also no significant correlation between PGD scores at 72 h and lung function at 6 and 12 months. The same applied to scintigraphic scores for heterogeneity at 3 months compared with lung function at 6 and 12 months. Fifty-five percent of all patients had decreased ventilation function measured in the period from 6 to 12 months. Forty-nine percent of the patients had normal perfusion evaluations, and 51% had abnormal perfusion evaluations at 3 months. For ventilation evaluations, 72% were normal and 28% were abnormal. There was a significant difference in the normal versus abnormal perfusion and ventilation scintigraphic images evaluated from the same patients. Ventilation was distributed more homogenously in the transplanted lung than perfusion in the same lung. The relative distribution of perfusion and ventilation to the transplanted lung of patients with and without a primary diagnosis of fibrosis did not differ significantly from each other. We conclude that PGD defined at 72 h does not lead to recognizable changes in ventilation-perfusion scintigrapy at 3 months, and scintigraphic findings do not correlate with development in lung function in the first 12 months.

To compare the corneal subbasal nerve density (SND) changes after laser in situ keratomileusis (LASIK) with a microkeratome and a femtosecond laser. Prospective clinical study. Sixty eyes of thirty myopes were included. Fifteen patients (30 eyes) underwent LASIK with the Moria II microkeratome, and the other 15 patients (30 eyes) with the 60 k Hz IntraLase femtosecond laser. Central, temporal and nasal corneal SNDs were measured by confocal microscopy and compared before surgery, 1 month, and 3 months after surgery. Analysis of variance and t test were used for comparing the differences between different time points and two groups. Preoperatively and 1 month, 3 months postoperatively, the SNDs were (16 728.30 ± 4 300.30), (1 875.42 ± 300.50) and (1 701.55 ± 194.11) µm/mm(2) in the central cornea, (11 379.70 ± 1 833.92), (1 341.20 ± 288.68) and (1 860.87 ± 147.60) µm/mm(2) in the temporal cornea, and (8 506.79 ± 662.83), (7 428.96 ± 712.99) and (8 044.32 ± 1 077.54) µm/mm(2) in the nasal cornea, respectively, in the microkeratome group, and (16 351.59 ± 3 503.88), (1 859.38 ± 452.93) and (2 043.67 ± 377.76) in the central cornea, (12 328.22 ± 2 007.43), (1 483.85 ± 371.28) and (2 126.31 ± 279.87) µm/mm(2) in the temporal cornea, and (8 347.91 ± 789.44), (1 475.53 ± 293.98) and (2 022.10 ± 282.89) µm/mm(2) in the nasal cornea, respectively, in the femtosecond laser group. The SNDs at three positions all decreased significantly at each time point postoperatively compared to the baseline values in both groups (1 and 3 months in the microkeratome group: central t = 18.981 and 18.912, temporal t = 30.121 and 27.921, and nasal t = 6.456 and 2.126; in the femtosecond laser group: central t = 22.667 and 22.379, temporal t = 29.000 and 28.376, and nasal t = 46.329 and 41.751; all P < 0.01, except 3 months at the nasal in the microkeratome group, P = 0.042). The nasal SND increased significantly from month 1 to month 3 (t = -3.921, P < 0.01) in the microkeratome group, and the temporal and nasal SNDs both increased significantly from month 1 to month 3 (t = -9.629 and -6.645, both P < 0.01) in the femtosecond group. There were no significant differences in the central SND between the two groups (F = 0.002, P = 0.96). Significant differences were found in the nasal SND between the groups at 1 month and 3 months (t = 42.281 and 29.608, both P < 0.01), and in the temporal SND at 3 months after surgery (t = -4.595, P < 0.01). Peripheral corneal nerve recovery occurred at 1 month after LASIK surgery. Patients with a femtosecond laser showed better corneal regeneration than those with a microkeratome.

ABSTRACT Introduction There is a growing interest in achieving higher survival rates with the lowest morbidity in localized prostate cancer (PC) treatment. Consequently, minimally invasive techniques such as low-dose rate brachytherapy (BT) and robotic-assisted prostatectomy (RALP) have been developed and improved. Comparative analysis of functional outcomes and quality of life in a prospective series of 51BT and 42Da Vinci prostatectomies DV Materials and Methods Comparative analysis of functional outcomes and quality of life in a prospective series of 93 patients with low-risk localized PC diagnosed in 2011. 51patients underwent low-dose rate BT and the other 42 patients RALP. IIEF to assess erectile function, ICIQ to evaluate continence and SF36 test to quality of life wee employed. Results ICIQ at the first revision shows significant differences which favour the BT group, 79% present with continence or mild incontinence, whereas in the DV group 45% show these positive results. Differences disappear after 6 months, with 45 patients (89%) presenting with continence or mild incontinence in the BT group vs. 30 (71%) in the DV group. 65% of patients are potent in the first revision following BT and 39% following DV. Such differences are not significant and cannot be observed after 6 months. No significant differences were found in the comparative analysis of quality of life. Conclusions ICIQ after surgery shows significant differences in favour of BT, which disappear after 6 months. Both procedures have a serious impact on erectile function, being even greater in the DV group. Differences between groups disappear after 6 months. PMID:28128908

This prospective, randomized study was performed to evaluate the results of mini-open and arthroscopic rotator cuff repair in a comparative case series of patients followed for 24 months. A total of 125 patients were randomized to mini-open (Group I) or arthroscopic (Group II) rotator cuff repair at the time of surgical intervention. The University of California Los Angeles (UCLA) score, the American Shoulder and Elbow Surgeons (ASES) index, and muscle strength were measured to evaluate the clinical results, while magnetic resonance arthrography was used at 24-month follow-up to investigate the postoperative rotator cuff integrity. Fifty-three patients in Group I and 55 patients in Group II were available for evaluation at 24-month follow-up. At 24-month follow-up, the UCLA score, the ASES index, and muscle strength were statistically significantly increased in both groups postoperatively, while no significant difference was detected between the 2 groups. Intact rotator cuffs were investigated in 42 patients in Group I and 35 in Group II, and there was a significant difference in postoperative structural integrity between the two groups (P < 0.05). When analysis was limited to the patients with full-thickness tear, the muscle strength of the shoulder was significantly better in Group II, and the retearing rate was significantly higher in Group II. Based on the results obtained from this study, it can be indicated that arthroscopic and mini-open rotator cuff repair displayed substantially equal outcomes, except for higher retearing rate in the arthroscopic repair group. While for patients with full-thickness tear, arthroscopic rotator cuff repair displayed better shoulder strength and significantly higher retearing rate as compared to mini-open rotator cuff repair at 24-month follow-up.

Similar to natural rivers, manmade inlets connect inland runoff to the ocean. Port Everglades Inlet (PEI) is a busy cargo and cruise ship port in South Florida, which can act as a source of pollution to surrounding beaches and offshore coral reefs. Understanding the composition and fluctuations of bacterioplankton communities ("microbiomes") in major port inlets is important due to potential impacts on surrounding environments. We hypothesize seasonal microbial fluctuations, which were profiled by high throughput 16S rRNA amplicon sequencing and analysis. Surface water samples were collected every week for one year. A total of four samples per month, two from each sampling location, were used for statistical analysis creating a high sampling frequency and finer sampling scale than previous inlet microbiome studies. We observed significant differences in community alpha diversity between months and seasons. Analysis of composition of microbiomes (ANCOM) tests were run in QIIME 2 at genus level taxonomic classification to determine which genera were differentially abundant between seasons and months. Beta diversity results yielded significant differences in PEI community composition in regard to month, season, water temperature, and salinity. Analysis of potentially pathogenic genera showed presence of Staphylococcus and Streptococcus . However, statistical analysis indicated that these organisms were not present in significantly high abundances throughout the year or between seasons. Significant differences in alpha diversity were observed when comparing microbial communities with respect to time. This observation stems from the high community evenness and low community richness in August. This indicates that only a few organisms dominated the community during this month. August had lower than average rainfall levels for a wet season, which may have contributed to less runoff, and fewer bacterial groups introduced into the port surface waters. Bacterioplankton beta diversity differed significantly by month, season, water temperature, and salinity. The 2013-2014 dry season (October-April), was warmer and wetter than historical averages. This may have driven significant differences in beta diversity. Increased nitrogen and phosphorous concentrations were observed in these dry season months, possibly creating favorable bacterial growth conditions. Potentially pathogenic genera were present in the PEI. However their relatively low, non-significant abundance levels highlight their relatively low risk for public health concerns. This study represents the first to sample a large port at this sampling scale and sequencing depth. These data can help establish the inlet microbial community baseline and supplement the vital monitoring of local marine and recreational environments, all the more poignant in context of local reef disease outbreaks and worldwide coral reef collapse in wake of a harsh 2014-16 El Niño event.

Studies have measured the effectiveness of tooth bleaching, however there are very few studies that have measured the persistence in color change after a 6-month follow-up. This study assessed the efficacy of the laser bleaching process using different regimens, and the persistence of color change over a 6-month period. Sixty patients divided into three equal groups were subjected to bleaching using a diode laser with 34% hydrogen peroxide. Group 1: patients subjected to one session of laser bleaching. Group 2: patients subjected to two sessions of laser bleaching with a 1-week interval. Group 3: the same as Group 2 but followed by home bleaching once a month for 3 months. The color was assessed four times: before bleaching, directly after bleaching, 3 months after bleaching, and 6 months after bleaching. All teeth had a significant color change at 6 months, but all teeth had regressed from the maximum value. There was significantly less regression in color for Group 3, followed by Groups 2 and 1, respectively. The combined technique of in-office laser bleaching for two sessions with a 1-week interval, followed by home bleaching once a month for 3 months gave more persistence in color change. In-office power bleaching using a laser assisted hydrogen peroxide system repeated after a week, combined with home bleaching once a month for 3 months, is an effective bleaching regimen with less color regression after 6 months compared to a regimen of in-office bleaching alone.

Osteochondral injuries have poor endogenous healing potential, and no standard treatment has been established. The use of combined layered autologous bone and cartilage chips for treatment of osteochondral defects has shown promising short-term clinical results. This study aimed to investigate the role of cartilage chips by comparing combined layered autologous bone and cartilage chips with autologous bone implantation alone in a Göttingen minipig model. The hypothesis was that the presence of cartilage chips would improve the quality of the repair tissue. Controlled laboratory study. Twelve Göttingen minipigs received 2 osteochondral defects in each knee. The defects were randomized to autologous bone graft (ABG) combined with autologous cartilage chips (autologous dual-tissue transplantation [ADTT]) or ABG alone. Six animals were euthanized at 6 months and 6 animals were euthanized at 12 months. Follow-up evaluation consisted of histomorphometry, immunohistochemistry, semiquantitative scoring (International Cartilage Repair Society II), and computed tomography. There was significantly more hyaline cartilage in the ADTT group (25.8%) compared with the ABG group (12.8%) at 6 months after treatment. At 12 months, the fraction of hyaline cartilage in the ABG group had significantly decreased to 4.8%, whereas the fraction of hyaline cartilage in the ADTT group was unchanged (20.1%). At 6 and 12 months, there was significantly more fibrocartilage in the ADTT group (44% and 60.8%) compared with the ABG group (24.5% and 41%). The fraction of fibrous tissue was significantly lower in the ADTT group compared with the ABG group at both 6 and 12 months. The implanted cartilage chips stained >75% positive for collagen type 4 and laminin at both 6 and 12 months. Significant differences were found in a number of International Cartilage Repair Society II subcategories. The volume of the remaining bone defect significantly decreased from 6 to 12 months in both treatment groups; however, no difference in volume was found between the groups at either 6 or 12 months. The presence of cartilage chips in an osteochondral defect facilitated the formation of fibrocartilage as opposed to fibrous tissue at both 6 and 12 months posttreatment. The implanted chips were present in the defect and viable after 12 months. This study substantiates the chondrogenic role of cartilage chips in osteochondral defects. © 2016 The Author(s).

To evaluate the effects of three different silicone hydrogel contact lenses (SHCL), (balafilcon A, senofilcon A, and comfilcon A) on tear function tests, corneal thickness, and ocular surface cytology in first time contact lens users. In this prospective study, 120 eyes of 60 subjects were evaluated. Balafilcon A users were designated as group 1, senofilcon A users as group 2, and comfilcon A users as group 3. In all cases, before and after 6 months of contact lens wear, ocular surface disease index score (OSDI), tear breakup time (TBUT), Schirmer 1 test, central corneal thickness (CCT), central corneal epithelium thickness (CCET), and conjunctival impression cytology samples were evaluated. In group 1, 40 eyes of the 20 patients, in group 2, 40 eyes of the 20 patients, and in group 3, 40 eyes of the 20 patients were evaluated. The mean OSDI scores did not differ between the three groups after contact lens wear (p > 0.05). In group 1 and group 2, significant decrease was found in the mean TBUT 6 months after contact lens wear (p = 0.04, p < 0.001, respectively). In group 3, after 6 months of contact lens wear, the mean Schirmer 1 tear test was decreased significantly (p = 0.021). In all 3 groups, no significant change was observed in the mean CCT and CCET after contact lens wear (p > 0.05). After 6 months, the morphological changes in temporal and superior conjunctival epithelial cells were found to be significant in all groups (p < 0.001). Six months after SHCL wear, marked morphological changes occurred in the conjunctival epithelium. Tear function tests were also affected, while corneal thickness did not show any significant difference.

Background: Aim of this clinical trial is the evaluation of the effect of intravitreal injection of bevacizumab on acute central serous chorioretinopathy (CSC). Materials and Methods: In a nonrandomized clinical trial, 36 CSC eyes (with <1-month disease history) were examined. Initially, all the patients underwent posterior and anterior segment examinations as well as complete eye examination to evaluate the best spectacle-corrected visual acuity (BSCVA). Then, optical coherence tomography was performed to confirm the diagnosis. The patients were divided to the two groups each of 18 subjects, which 18 patients received intravitreal injection of bevacizumab (1.25 mg) and the rest of them did not receive any treatment (control group). The patients were health checked by the end of the 1st and 3rd months. Significance level was considered as P < 0.05. Results: In the BSCVA, no significant difference in visual improvement was observed in baseline vision compared to each other (P = 0.481). There was also no significant difference in the vision of intervention and control groups 1 and 3 months after injection (P = 0.379 and P = 0.557). A significant decrement existed in the intervention group compared with the control group in the maximum central macular thickness at 1 month after injection (P = 0.001); however, the difference was not significant when comparing the two groups at baseline and 3 months after injection (P = 0.925 and P = 0.338). Conclusion: In general, according to the results of this study, intravitreal injection of bevacizumab was not effective in improvement of patients with acute CSC, although it had no side effects.

The objective of this study was to observe the antihypertensive effect of losartan and levamlodipine besylate on insulin resistance in patients with essential hypertension (EH) combined with isolated impaired fasting glucose (i-IFG). Patients (n=244) were randomly assigned to losartan potassium tablets (50-100 mg per day) or levamlodipine besylate tablets (2.5-5.0 mg per day) for intensive antihypertensive treatment with no lifestyle interventions for 3 years. The changes in fasting plasma glucose, fasting insulin (FINS) and insulin sensitivity index (ISI) from before to after treatment were observed. Blood pressure (BP) in each group was significantly reduced by treatment (P<0.05). After 12 months of treatment, the FINS level in the losartan potassium group was significantly decreased and ISI was significantly increased compared with before treatment (P<0.05) and compared with the levamlodipine besylate group (P<0.05). After 24 and 36 months of treatment, FINS was significantly decreased and ISI was significantly improved in both groups compared with baseline (P<0.05), and there was no difference between the groups (P>0.05). The incidence of new-onset diabetes mellitus was not significantly different between two groups. The antihypertensive effect of losartan and levamlodipine besylate could amoliorate insulin resistance in patients with EH combined with i-IFG. The improvement of insulin resistance by losartan potassium at 12 months might be better than that by levamlodipine besylate; however, after 24 and 36 months of follow-up, both agents significantly alleviated insulin resistance. These results suggest that the effects of these two drugs on insulin resistance are not significantly different.

Purpose Premenopausal women with breast cancer receiving adjuvant chemotherapy are at risk for amenorrhea. The National Surgical Adjuvant Breast and Bowel Project B-30 trial included menstrual history (MH) and quality-of-life (QOL) studies to compare treatments on these outcomes. Patients and Methods Patients were randomly assigned to sequential doxorubicin (A) and cyclophosphamide (C) followed by docetaxel (T; AC→T), concurrent TAC, or AT, which varied in duration (24, 12, 12 weeks, respectively), and use of C. Endocrine therapy was prescribed for women with hormone receptor–positive tumors. MH and QOL were assessed with standardized questionnaires at baseline; cycle 4, day 1; and every 6 months through 24 months. Prespecified analyses examined rates of amenorrhea by treatment arm, the relationship between amenorrhea and QOL, and QOL by treatment arm. Results Amenorrhea 12 months after random assignment was significantly different between treatment groups: 69.8% for AC→T, 57.7% for TAC, and 37.9% for AT (P < .001). The AT group without tamoxifen had the lowest rate of amenorrhea. QOL was poorer for patients receiving AC→T at 6 months but similar to others by 12 months. Post-treatment symptoms were increased above baseline for all treatments. Multivariable repeated measures modeling demonstrated that treatment arm, time point, age, and tamoxifen use were significantly associated with symptom severity (all P values < .002). Conclusion Amenorrhea rates differed significantly by treatment arm, with the AT arm having the lowest rate. Patients treated with longer duration therapy (AC→T) had greater symptom severity and poorer QOL at 6 months, but did not differ from shorter duration treatments at 12 months. PMID:21300930

The objective of this (trial-based) economic evaluation was, from a societal perspective, to compare the cost-effectiveness of a multicomponent self-management intervention (MCI) with care as usual (CAU) in adult patients with epilepsy over a 12-month period. In a randomized-controlled trial, participants were randomized into intervention or CAU group. Adherence, self-efficacy (Epilepsy Self-Efficacy Scale [ESES]), quality-adjusted life years (QALYs), healthcare costs, production losses, and patient and family costs were assessed at baseline and during the 12-month study period. Incremental cost-effectiveness ratios (ICERs) (i.e., cost per increased adherence, self-efficacy, or QALY), and cost-effectiveness acceptability curves were calculated. In total, 102 patients were included in the study, of whom 52 were in the intervention group. Adherence rates over 6 months were 63.7% for the CAU group and 75.9% for the intervention group. Adherence, ESES, and quality of life did not differ significantly between groups. An ICER of €54 per point increase in ESES score at 6 months and €1,105 per point increase at 12-month follow-up was found. The intervention resulted in an ICER of €88 per percentage of adherence increase at 6 months. ICERs of €8,272 and €15,144 per QALY gained were found at 6- and 12-month follow-up, respectively. Although no statistically significant difference was found after baseline adjustments, cost-effectiveness estimates for MCI appear promising. As rules of inference are arbitrary, it has been argued that decisions should be based only on the net benefits, irrespective of whether differences are statistically significant. Hence, the MCI may be a cost-effective addition to the current standard care for adults with epilepsy. Wiley Periodicals, Inc. © 2017 International League Against Epilepsy.

We conducted a systematic review and meta-analysis investigating the components and effectiveness of self-help weight-loss interventions and their applicability to less-advantaged populations. We searched (November 2013) for randomized controlled trials comparing self-help interventions with each other or with minimal controls in overweight and obese adults, with 6 months or longer follow-up. We calculated mean difference between intervention and control for 6- and 12-month weight change. Twenty-three studies met the inclusion criteria (9632 participants; 39 intervention arms). Intervention participants lost significantly more weight than controls at 6 months (mean difference −1.85 kg; 95% confidence interval [CI] = −2.86, −0.83; 7 studies). No significant effect was detected at 12 months but results were sensitive to the inclusion of 1 study at high risk of bias. Interactive programs appeared more effective than standard ones at 6 months (mean difference −0.94 kg; 95% CI = −1.50, −0.38). Evidence is insufficient to reach conclusions on effectiveness in socioeconomically disadvantaged people, but suggests self-help interventions may be less effective in this group. PMID:25602873

Partial fundoplications provide similar reflux control with fewer post-fundoplication symptoms compared with Nissen fundoplication for gastro-oesophageal reflux disease (GORD). The best choice of procedure for partial fundoplication remains unclear. The aim of this study was to compare the outcome of two different types of partial fundoplication for GORD. A double-blind RCT was conducted between 2012 and 2015 in two hospitals specializing in antireflux surgery. Patients were randomized to undergo either a laparoscopic 270° posterior fundoplication (Toupet) or a laparoscopic 180° anterior fundoplication. The primary outcome was postoperative dysphagia at 12 months, measured by the Dakkak score. Subjective outcome was analysed at 1, 3, 6 and 12 months after surgery. Objective reflux control was assessed before and 6 months after surgery. Ninety-four patients were randomized to laparoscopic Toupet or laparoscopic 180° anterior fundoplication (47 in each group). At 12 months, 85 patients (90 per cent) were available for follow-up. Objective scores were available for 76 (81 per cent). Postoperative Dakkak dysphagia score at 12 months was similar in the two groups (mean 5·9 for Toupet versus 6·4 for anterior fundoplication; P = 0·773). Subjective outcome at 12 months demonstrated no significant differences in control of reflux or post-fundoplication symptoms. Overall satisfaction and willingness to undergo surgery did not differ between the groups. Postoperative endoscopy and 24-h pH monitoring showed no significant differences in mean oesophageal acid exposure time or recurrent pathological oesophageal acid exposure. Both types of partial fundoplication provided similar control of GORD at 12 months, with no difference in post-fundoplication symptoms.

Social cognition in infancy is evident in coordinated triadic engagements, that is, infants attending jointly with social partners and objects. Current evolutionary theories of primate social cognition tend to highlight species differences in cognition based on human-unique cooperative motives. We consider a developmental model in which engagement experiences produce differential outcomes. We conducted a 10-year-long study in which two groups of laboratory-raised chimpanzee infants were given quantifiably different engagement experiences. Joint attention, cooperativeness, affect, and different levels of cognition were measured in 5- to 12-month-old chimpanzees, and compared to outcomes derived from a normative human database. We found that joint attention skills significantly improved across development for all infants, but by 12 months, the humans significantly surpassed the chimpanzees. We found that cooperativeness was stable in the humans, but by 12 months, the chimpanzee group given enriched engagement experiences significantly surpassed the humans. Past engagement experiences and concurrent affect were significant unique predictors of both joint attention and cooperativeness in 5- to 12-month-old chimpanzees. When engagement experiences and concurrent affect were statistically controlled, joint attention and cooperation were not associated. We explain differential social cognition outcomes in terms of the significant influences of previous engagement experiences and affect, in addition to cognition. Our study highlights developmental processes that underpin the emergence of social cognition in support of evolutionary continuity. © 2014 The Authors.

Aim of this study was to determine the effect of high dose vitamin D given to patients with early diabetic renal disease on systolic and diastolic blood pressure, total cholesterol (TC), low-density lipoproteins (LDL), triglycerides (TG) and high density lipoproteins (HDL) in a randomized controlled trial MATERIALS AND METHOD: Patients with early diabetic nephropathy were recruited. Selected patients were allocated to two groups by Block randomization method. Treatment group received 50,000 IU of vitamin D3 intramuscularly and the control group was given an equal volume of distilled water (0.25mL) monthly for six months. Blood and urine were collected at the baseline for biochemical analyses and blood pressure was measured. After six months all the measurements done at the baseline were repeated. Of 155 patients invited, 85 were randomly assigned to two groups. No significant differences were found between treatment and control groups at the baseline. Vitamin D therapy significantly reduced DBP, total cholesterol and LDL but the between group differences were not significant. There was an increase in HDL cholesterol level in the treatment group while there was no change in the control group Between groups difference was significant (P=<0.001). There was a significant improvement of serum HDL level with six months therapy of high dose vitamin D in patients with early diabetic nephropathy. Copyright © 2017 Diabetes India.

The growth rate of triploid European aspen (Populus tremula L.) and hybrid aspen (P. tremula × Populus tremuloides Michx.) significantly exceeds that of diploid aspen, but the underlying physiological controls of the superior growth rates of these genotypes are not known. We tested the hypothesis that the superior growth rate of triploid and hybrid aspen reflects their greater net photosynthesis rate. Micropropagated clonal plants varying in age from 2.5 to 19 months were used to investigate the ploidy and plant age interaction. The quantum yield of net CO2 fixation (Φ) in leaves of young 2.5-month-old hybrid aspen was lower than that of diploid and triploid trees. However, Φ in 19-month-old hybrid aspen was equal to that in triploid aspen and higher than that in diploid aspen. Φ and the rate of light-saturated net photosynthesis (ANS) increased with plant age, largely due to higher leaf dry mass per unit area in older plants. ANS in leaves of 19-month-old trees was highest in hybrid, medium in triploid and lowest in diploid aspen. Light-saturated photosynthesis had a broad temperature optimum between 20 and 35 °C. Rate of respiration in the dark (RDS) did not vary among the genotypes in 2.5-month-old plants, and the shape of the temperature response was also similar. RDS increased with plant age, but RDS was still not significantly different among the leaves of 19-month-old diploid and triploid aspen, but it was significantly lower in leaves of 19-month-old hybrid plants. The initial differences in the growth of plants with different ploidy were minor up to the age of 19 months, but during the next 2 years, the growth rate of hybrid aspen exceeded that of triploid plants by 2.7 times and of diploid plants by five times, in line with differences in ANS of 19-month-old plants of these species. It is suggested that differences in photosynthesis and growth became more pronounced with tree aging, indicating that ontogeny plays a key role in the expression of superior traits determining the productivity of given genotypes. © The Author 2014.

Aseptic loosening and osteolysis are the most common indications after TKA for revision surgery. This meta-analysis which included high-quality randomized controlled trials (RCTs) aimed to analyze the effect of bisphosphonates (BPs) on maintaining periprosthetic bone mineral density (BMD) after total knee arthroplasty. PubMed, AMED, EMBASE, the Cochrane library, ISI Web of Science, and China National Knowledge Infrastructure were systematically searched, five RCTs were included and the total number of participants was 188. The weighted mean differences with 95% confidence interval were calculated to evaluate the efficacy of BPs on total BMD of knee and the BMD of different periprosthetic regions. A descriptive review was performed for BP-related adverse effects. The BPs group presented significantly higher total BMD in proximal part of the tibia than the control group at 3 and 6 months (P < 0.05), but no significant difference at 12 months (P = 0.09). The BPs group presented significantly higher BMD in the distal aspect of the femur than that in the control group at 3, 6, 12 months. The BPs group presented significantly higher periprosthetic BMD than that in the control group at 3, 6 and 12 months in tibial medial and lateral metaphyseal region, and femoral anterior, central and posterior metaphyseal region (p < 0.05), but no significant difference for tibial diaphyseal region at 3, 6, and 12 months. None of the included studies described severe or fatal adverse effects related to BPs. BPs have a short-term effect on reducing periprosthetic bone loss after total knee arthroplasty. Compared with diaphyseal region, BPs are more effective on the preservation of BMD in medial lateral metaphyseal regions of proximal tibia and in anterior, central, and posterior metaphyseal region of distal femur.

Carcass characteristics of 336 kids from the Neuquén Criollo breed were evaluated. Two categories were taken into account: three months and 5 to 7 months kids. Live weight, carcass weights, measurement and indexes of 304 kids were calculated in a study done in a commercial slaughterhouse located in Chos Malal town. Thirty two carcass left sides were dissected into the major components: muscle, bone, fat and remaining tissues. Three months kids were compared with 5 to 7 months kids. The slaughter live weight of the former was 16.3kg and the latter was 22.4kg. Cold carcass weight and dressing percentage differed significantly (p<0.001) between age categories. Three months kids had a higher percentage of bones (26.8 vs. 21.7%; p<0.001) and a lower percentage of fat (10.8 vs. 15%; p<0.01) than those at 5-7 months, but both had similar percentages of muscle (56.4 vs. 57%; p=NS). There were significant differences in the percentages of primal carcass cuts: hind leg (32 vs. 34%; p<0.001), shoulder (22 vs. 20%; p<0.001) and neck, (10 vs. 8%; p<0.01) for three months vs. 5-7 months old kids, respectively.

Purpose: To compare surgical outcomes in neovascular glaucoma patients who underwent trabeculectomy with mitomycin C versus Ahmed Glaucoma Valve implantation. Patients and methods: This was a retrospective comparative case series. We reviewed 40 eyes of 39 patients with underlying diagnosis of neovascular glaucoma, divided into two groups: Ahmed Glaucoma Valve (N = 20) and trabeculectomy with mitomycin C (N = 20). Surgical success was defined as 6 mm Hg ≤ intraocular pressure ≤21 mm Hg, with or without the use of glaucoma medications, with no further glaucoma surgery, and light perception or better vision. Early postoperative hypotony was defined as intraocular pressure <5 mm Hg during the first postoperative week. Results: The average follow-up was 31 months (range 6–87 months) for the Ahmed Glaucoma Valve group and 25 months (6–77 months) for the trabeculectomy group. Although the mean number of postoperative intraocular pressure-lowering medications was significantly higher in the trabeculectomy group compared with the Ahmed Glaucoma Valve group at 3 and 6 month time points, there was no statistically significant difference at any other time point. There was no statistically significant difference between both groups in postoperative visual acuity and intraocular pressure. Success was 70% and 65% at 1 year and 60% and 55% at 2 years after Ahmed Glaucoma Valve and trabeculectomy, respectively. Kaplan–Meier survival curve analysis showed no significant difference in success between the two groups (P = 0.815). Hyphema was the most common complication in both groups. Conclusion: We found similar results after trabeculectomy with mitomycin C and Ahmed Glaucoma Valve implantation in eyes with neovascular glaucoma. PMID:21468334

The present study aims to investigate whether the distribution of the Basic Life Support and Automated External Defibrillation (BLS/AED) manual, 4 weeks prior to the course, has an effect on skill acquisition, theoretical knowledge and skill retention, compared with courses where manuals were not distributed. A total of 303 laypeople were included in the present study. The courses were randomised with sealed envelopes in 12 courses, where manuals were distributed to participants (group A) and in 12 courses, where manuals were not distributed to participants (group B). The participants were formally evaluated at the end of the course, and at 1, 3 and 6 months after each course. The evaluation procedure was the same at all time intervals and consisted of two distinct parts: a written test and a simulated cardiac arrest scenario. No significant difference was observed between the two groups in skill acquisition at the time of initial training. Furthermore, there was no significant difference between the groups in performing BLS/AED skills at 1, 3 and 6 months after initial training. Theoretical knowledge in either group at the specified time intervals did not exhibit any significant difference. Significant deterioration of skills was observed in both groups between initial training and at 1 month after the course, as well as between the first and third month after the course. The present study shows that distribution of BLS/AED manuals 1 month prior to the course has no effect on theoretical knowledge, skill acquisition and skill retention in laypeople.

To compare changes in corneal endothelial cell density (CECD) after Ahmed glaucoma valve (AGV) implantation and trabeculectomy. Changes in corneal endothelium in patients that underwent AGV implantation or trabeculectomy were prospectively evaluated. Corneal specular microscopy was performed at the central cornea using a non-contact specular microscope before surgery and 6 months and 12 months after surgery. The CECD, hexagonality of the endothelial cells, and the coefficient of variation of the cell areas were compared between the two groups. Forty eyes of 40 patients with AGV implantation and 28 eyes of 28 patients with trabeculectomy were studied. Intraocular pressure in the AGV implantation group was significantly higher than that in the trabeculectomy group ( p < 0.001), but there was no significant difference in other clinical variables between the two groups. In the AGV implantation group, the mean CECD significantly decreased by 9.4% at 6 months and 12.3% at 12 months compared with baseline values (both, p < 0.001), while it decreased by 1.9% at 6 months and 3.2% at 12 months in the trabeculectomy group ( p = 0.027 and p = 0.015, respectively). The changes at 6 months and 12 months in the AGV implantation group were significantly higher than those in the trabeculectomy group ( p = 0.030 and p = 0.027, respectively). In the AGV implantation group, there was a significant decrease in the CECD between baseline and 6 months and between 6 months and 12 months ( p < 0.001 and p = 0.005, respectively). However, in the trabeculectomy group, a significant decrease was observed only between baseline and 6 months ( p = 0.027). Both the AGV implantation group and the trabeculectomy group showed statistically significant decreases in the CECD 1 year after surgery. The decrease in CECD in the AVG implantation group was greater and persisted longer than that in the trabeculectomy group.

Object To investigate white matter structural abnormalities using diffusion tensor imaging (DTI) in children with hydrocephalus before CSF diversionary surgery (including ventriculoperitoneal shunting and endoscopic third ventriculoscopy) and the course of recovery post-surgery in association with neuropsychological and behavioral outcome. Methods This was a prospective study that included 54 children with congenital hydrocephalus (21F/33M; age range: 0.03–194.5 months) who underwent surgery and 64 normal controls (30F/34M, age range: 0.30–197.75 months). DTI and neurodevelopmental outcome data were collected once in the control group and at pre-surgery, 3-month, and 12-month post-surgery in the patients. DTI measures, including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) values were extracted from the genu of corpus callosum (gCC) and the posterior limb of internal capsule (PLIC). Group analysis was performed first cross-sectionally to quantify DTI abnormalities at three time points by comparing the controls and the patients group at the three time points separately. Longitudinal comparisons were conducted pairwise between different time points in patients whose data were acquired at multiple time points. Neurodevelopmental data were collected and analyzed using the Adaptive Behavior Assessment System, Second Edition (ABAS-II) and the Bayley Scales of Infant Development, Third Edition (Bayley-III). Correlation analyses were performed between DTI and behavioral outcomes. Results Significant DTI abnormalities were found in both the gCC (lower FA and higher MD, AD, and RD) and the PLIC (higher FA, lower AD and RD) at pre-surgery. The DTI measures in the gCC remained mostly abnormal at 3-month and 12-month post-surgery. The DTI abnormalities in the PLIC were significant in FA and AD at 3-month post-surgery but did nor persist when tested at 12-month post-surgery. Significant longitudinal DTI changes in the patients were found in the gCC between 3-month and 12-month post-surgery. In the PLIC, trend level longitudinal changes were found between pre-surgery and 3-month post-surgery as well as between 3-month and 12-month post-surgery. Significant correlation between DTI and developmental outcome were found at all three time points. Notably, significant correlation was found between DTI in the PLIC at 3-month post-surgery and developmental outcome at 12-month pots-surgery. Conclusion Our data showed significant WM abnormality based on DTI in both the gCC and the PLIC in children with congenital hydrocephalus before surgery and the abnormalities persisted in both the gCC and the PLIC at 3-month post-surgery. The DTI values remained significantly abnormal in the gCC at 12-month post-surgery. Longitudinal analysis showed signs of recovery in both WM structures between different time points. Combined with the significant correlation found between DTI and neuropsychological outcome, our study suggests that DTI can serve as a sensitive imaging biomarker for underlying neuroanatomical changes and post-surgical developmental outcome and even as a predictor for future outcomes.

Aim: The purpose of the present randomized clinical trial was to evaluate the color change, rebound effect and sensitivity of at-home bleaching with 15% carbamide peroxide and power bleaching using 38% hydrogen peroxide. Materials and Methods: For bleaching techniques, 20 subjects were randomized in a split mouth design (at-home and power bleaching): In maxillary and mandibular anterior teeth (n = 20). Color was recorded before bleaching, immediately after bleaching, at 2 weeks, 1, 3 and 6 month intervals. Tooth sensitivity was recorded using the visual analog scale. The Mann-Whitney test was used to compare both groups regarding bleaching effectiveness (ΔE1), rebound effect (ΔE2) and color difference between the rebounded tooth color and unbleached teeth (ΔE3) while the Wilcoxon compared ΔE within each group. Distribution of sensitivity was evaluated using the Chi-square test (α =0.05). Results: There was no significant difference between groups regarding ΔE1 and ΔE3 (P > 0.05). Even though, ΔE2 showed no significant difference between groups after bleaching as well as at 2 week, 1 month and 3 month follow-up periods (P > 0.05). Although, significant difference was found in ΔE2 (P < 0.05 Mann-Whitney) between two methods after 6 months and a high degree of rebound effect was obtained with power bleaching. Within each group, there was no significant difference between ΔE1 and ΔE3 (P < 0.05 Wilcoxon). The distribution of sensitivity was identical with both techniques (P > 0.05). Conclusion: Bleaching techniques resulted in identical tooth whitening and post-operative sensitivity using both techniques, but faster color regression was found with power bleaching even though color regression to the baseline of the teeth in both groups was the same after 6 months.

To evaluate and compare the physical and chemical properties of four different dental cements under long-term water storage. A glass-ionomer cement (A:Fuji I), a resin reinforced glass-ionomer (B: Fuji Plus), a self-adhesive resin cement (C:G-Cem), and an etch & rinse resin cement (D: Duolink) were taken as samples. According to ISO 4049, water sorption and solubility of four resin cements under different storage times (1 week, 1, 3, 6 and 12 months) were calculated (n = 5), meanwhile their surface Knoop micro hardness values were measured. Surface cracks were detected on sample B and C after 12 months. Sample A was fragmentized after 6 months. Sample B showed significantly lower surface hardness after 12 months than it did after the first 24 hours of water storage (P < 0.05). Sample D showed significantly lower water sorption than other cements did at all exam time point. The highest water sorption values were observed in Sample D after 1 month [(40.8±2.5) µg/mm(3)], in Sample B after 3 months [(551.3±22.5) µg/mm(3)], in Sample C after 12 months [(147.5±8.3) µg/mm(3)]. The highest solubility values were detected in Sample B after 3 months [(105.3±10.5) µg/mm(3)], in Sample C after 12 months [(79.3 ± 6.2) µg/mm(3)], and in Sample D after 12 months [(23.9 ± 6.9) µg/mm(3)]. Among the four types of cements, the etch & rinse resin cement showed the best stability of physical and chemical properties under long-term water storage.

To determine whether Whole Body Vibration Training (WBVT) is effective at improving pelvic floor muscles strength in women with Stress Urinary Incontinence (SUI). The study was designed as a randomized clinical trial. 43 women with SUI were randomly assigned in two groups; WBVT and Pelvic Floor Muscle Training (PFMT) and received interventions for four weeks. Pelvic floor muscle (PFM) strength, quality of life and incontinence intensity were evaluated. All measurements were conducted pre and post intervention and also after 3 months in all participants. The ANOVA and the independent sample t test were applied respectively to determine the differences in each group and between the groups. This study showed the WBVT protocol in this study was effective in pelvic floor muscles strength similar to PFMT, and also in reducing the severity of incontinence and increasing I-QOL questionnaire score. We found significant differences in each group pre and post intervention (p = 0.0001); but no significant difference in comparison of two groups' outcomes. Also after three-month follow up, there was no significant difference between groups. The findings of this study showed the beneficial effects of WBVT in improving pelvic floor muscles strength and quality of life in patients with urinary incontinence in four-week treatment period and after three months follow up.

Objective : To describe and compare speech and phonology at age 3 years in children born with unilateral complete cleft lip and palate treated with three different methods for primary palatal surgery. Design : Prospective study. Setting : Primary care university hospitals. Participants : Twenty-eight Swedish-speaking children born with nonsyndromic unilateral complete cleft lip and palate. Interventions : Three methods for primary palatal surgery: two-stage closure with soft palate closure between 3.4 and 6.4 months and hard palate closure at mean age 12.3 months (n = 9) or 36.2 months (n = 9) or one-stage closure at mean age 13.6 months (n = 10). Main Outcome Measures : Based on independent judgments performed by two speech-language pathologists from standardized video recordings: percent correct consonants adjusted for age, percent active cleft speech characteristics, total number of phonological processes, number of different phonological processes, hypernasality, and audible nasal air leakage. The hard palate was unrepaired in nine of the children treated with two-stage closure. Results : The group treated with one-stage closure showed significantly better results than the group with an unoperated hard palate regarding percent active cleft speech characteristics and total number of phonological processes. Conclusions : Early primary palatal surgery in one or two stages did not result in any significant differences in speech production at age 3 years. However, children with an unoperated hard palate had significantly poorer speech and phonology than peers who had been treated with one-stage palatal closure at about 13 months of age.

The purpose of this article was to evaluate the influence of cobalt-chromium (Co-Cr) alloy as the material of inner crown on periodontal tissue through detecting the weight of diseased teeth and the concentration of aspartate transaminase (AST) and alkaline phosphatase (ALP) of the gingival crevicular fluid (GCF) after Co-Cr alloy ceramics repairing. In this study, thirty cases of clinical diseased teeth were chosen from thirty patients based on patients' consent. Each tooth conformed to the inclusion criteria. All of the thirty teeth were repaired with Co-Cr alloy ceramics according to the indications. Then GCF of each diseased tooth was collected and weighed at the time of the day before prosthesis, the first and third month after repairing respectively in order to detect the concentration of AST and ALP. Furthermore, comparative analysis for different periods was performed after the data statistics. To the weight of GCF and the concentration of AST after the respective comparison of three indexes which was of different periods, numerous of each index increased in accordance with the rule of preoperation, postoperative first month, and postoperative third month (P < 0.05). To the concentration of ALP at three time points, the compared results showed that the preoperative numerous was less than that of third month after operation and there was significant difference between them (P < 0.05). To the weight of GCF and the concentration of AST and ALP, after the respective comparison of three indexes which was the diseased teeth and the contralateral teeth with the same name in the periods of pre-operation, all the differences had no statistical significance (P > 0.05), but all the differences had statistical significance in the periods of postoperative third month (P < 0.05). During the next three months after operation, GCF weight, concentration of AST and ALP of diseased teeth was gradually increased after their Co-Cr alloy ceramics crown repairing. This increase is somewhat harmful to periodontal health.

To analyze the effect of the posterior cruciate ligament (PCL) retaining or not on knee-joint proprioception by comparing the proprioceptive difference between PCL retaining and no PCL retaining in total knee arthroplasty (TKA). Between June 2009 and June 2010, 38 osteoarthritis patients meeting the inclusion criteria were divided into PCL retaining group (group A, n=19) and PCL-substituting group (group B, n=19) according to the random number table. There was no significant difference in gender, age, disease duration, the range of motion of the knee between 2 groups (P > 0.05). The effectiveness and the knee-joint proprioception were separately assessed by the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) score and the passive angle reproduction test (30, 60, and 90 degrees of knee flexion) preoperatively and 12 months postoperatively. All incisons healed by first intention, without complications of infection, fracture, and deep vein thrombosis of lower limb. The patients were followed up 12-17 months (mean, 14.1 months). The knee function after operation was obviously improved when compared with preoperative one; significant differences were observed in the WOMAC scores and the results of passive angle reproduction test between at preoperation and at 12 months after operation (P < 0.05), but no significant difference was found between group A and group B (P > 0.05). Whether PCL retaining or not in TKA both can improve knee-joint proprioception, and no obvious difference between them.

To study the effects of different types of prosthesis used in ossiculoplasty on mastoidectomy of treating chronic otitis media. One hundred and forty three patients with chronic otitis media were treated by canal wall-down tympanoplasty with ossiculoplasty in a single stage. According to material of prosthesis, they were classified as titanium group (group A, 52 cases), hydroxypatite group (group B, 47 cases) and autogenous bone group(group C, 44 cases). The postoperative complication and hearing thresholds were analyzed in the 24 months follow-up. Average postoperative air-conduction gain and air-bone gap were measured at four frequencies: 0.5, 1.0.2, and 4.0 kHz. 12-month after operation, the average air threshold and air-bone gaps of the three groups were reduced (P < 0.05). The reconstruction successful rate (78.7%) of group A was slightly better than that of B, C (68.1%, 70.4%), there was no statistically significant difference. The difference of the average air threshold and air-bone gaps of group B, C after 24-month of operation and 12-month after operation was statistically significant (P < 0.05). The reconstruction successful rate (48.9%, 45.5%) of group B, C was lower than that of A (76.9%), the difference was also statistically significant (P < 0.05). Prostheses using titanium type could give good functional results and strong stability with low complication.

Medical treatment has been widely used in peptic ulcer disease, however perforation is a severe complication. The rationale of this study was to evaluate the effect of Islamic Ramadan fasting on peptic ulcer perforation. Patients (No. 2311) who were operated on due to peptic ulcer perforation in a teaching and reference Hospital of a State University from January 1979 to January 2016 were analyzed. Patients were divided into two groups. Group I (No. 1805) included patients who were operated during other periods of the years without Ramadan fasting (396 months), while Group II (No. 506) constituted of patients who were operated on during the fasting periods (36 months). There was no significant difference in the mean ages between the groups (38 vs. 42 years). The mean monthly number of surgical intervention rates was higher in Group II (14.05 vs. 4.55, p < 0.001). There was a statistically significant rise in the number of male patients during Ramadan months (p = 0.0073). While omentoplasty with upper midline laparotomy vs. other surgical methods was significantly more employed in Group II (p = 0.0024), mortality rates were similar as 2.27 and 2.56% in Group I and II, respectively (p > 0.05). We could not detect any seasonal differences, although hot summer days constituted the longest fasting durations (19 hours) in the country. This study suggested that the occurrence of peptic ulcer perforation was significantly high during Ramadan fasting months due to the long fasting periods especially with significant male predominance.

For the first time, the development of paw preferences in the domestic cat, Felis silvestris catus, is explored. Twelve cats were tested at ages 12 weeks, 6 months, and 1 year on a challenge requiring them to use one of their paws to retrieve food. To control for repeated testing of the same cats at different ages, the subjects' paw preferences were compared with those of cats tested just once, at 6 months (n = 11) or 1 year (n = 14) of age. Analysis revealed a significant effect of age on the distribution of cats' paw preferences. Cats were significantly more likely to be ambilateral than paw preferent at 12 weeks and at 6 months but more likely to display a lateral bias in paw use at 1 year. There was a significant positive correlation between cats' paw preferences at 6 months and at 1 year. Lateralized behavior was strongly sex related. Females had a greater preference for using their right paw; males were significantly more inclined to adopt their left. Analysis revealed no significant difference in the direction or strength of paw preferences of cats tested longitudinally or cross-sectionally at 6 months or 1 year of age. Findings indicate that cats develop paw preferences by 1 year and hint at a relative stability in preferred paw use over time. The strong sex effect observed strengthens the case for the influence of a biological mechanism in the emergence of motor asymmetry in cats.

Soil arthropods are an important component of agroecosystems, contributing significantly to their biodiversity and functioning. However, seasonal patterns, population dynamics, and significant roles of these soil arthropods in improvement of soil structures and functions are influenced by many factors. The objective of the current study was to investigate soil arthropod abundance in relation to a blend of meteorological and edaphic factors and to find out the difference in abundance among various crops (sugarcane, cotton, wheat, alfalfa fodder, and citrus orchards). The arthropod sampling was done by pitfall traps and Tullgren extractions on fortnightly intervals. Soil temperature and relative humidity were noted on the field sites while analysis for soil pH, organic matter, and soil moisture contents were done in the laboratory. The rainfall data was obtained from an observatory. Results showed that significant differences were found in soil arthropod abundance across different sampling months and crops. Out of total 13,673 soil arthropods sampled, 38 % belonged to Collembola, followed by 15 % Hymenoptera, 15 % Acarina, 11 % Myriapods, 6 % Coleoptera, 5 % Orthoptera, and 5 % Araneae. Mean abundance per sample was highest in summer months as compared to winter. Overall abundance per sample was significantly different between all crops ( p < 0.05). Cluster analysis revealed four categories of soil arthropods according to abundance, i.e., highly abundant (Collembola, Acarina, Myripoda, Hymenoptera), moderately abundant (Orthoptera, Aranae, Coleoptera), least abundant (Dermaptera, Hemiptera, Diptera), and rare (Blattaria, Isoptera, Diplura, Lepidoptera). Soil temperature and soil organic matter showed significant positive correlation with abundance, while relative humidity was significantly negatively correlated. Soil moisture and soil pH showed no significant correlations while no correlation was found with total rainfall. PCA analysis revealed that soil surface arthropods were the major contributors of variation in overall abundance in extreme temperature months while microarthropods in low-temperature months. CCA analysis revealed the occurrence of different arthropod groups in correspondence with different abiotic variables. Results are discussed in view of position of these arthropods as useful indicators under changing environmental conditions impacting agroecosystems in the study area.

To determine the clinical efficacy of posterior intervertebral surgery for single-segment thoracolumbar spinal tuberculosis.
 Methods: Clinical data were retrospectively analyzed in 62 patients with thoracolumbar spinal tuberculosis who underwent posterior intervertebral surgery (A group) or posterior and anterior combined intervertebral surgery (B group) from January 2010 to January 2015 in Department of Spinal Surgery, General Hospital, Ningxia Medical University. The operative time, blood loss, length of hospital stay, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level, neurological function, VAS score, vertebral Cobb angle, bone healing, and postoperative complications were compared between the 2 groups.
 Results: All patients were followed up for 10 to 30 (average 22) months after the operation. In the A group, operative time, blood loss, and hospital stay were less than those in the B group (P<0.05). In the follow-up, the pain of patients was alleviated and nervous function was improved obviously in the 2 groups compared with pre-operation. The ESR and CRP at the 6 months after operation returned to the normal range in patients of the 2 groups. There were significant differences in the ESR and CRP among the pre-operation, the 6 months after operation, and the end of follow-up within the group (P<0.05), while there were no significant differences in ESR and CRP between the 6 months after operation and the end of follow-up (P>0.05). There were no significant differences in the ESR and CRP among the pre-operation, the 6 months after operation, and the end of follow-up in the 2 group (P>0.05). The Cobb angles after the operation and the end of follow-up were significanthy smaller than those before the operation (P<0.01), while there were no significant differences in Cobb angle before operation, after the operation, and the end of follow-up between the 2 groups (P>0.05). There were no significant differences in the bone healing rate at 6 months or 1 year after operation between the A group and B group (P>0.05) and the complication rate of the A group was lower than the B group (P<0.01).
 Conclusion: Clinical efficacy of posterior intervertebral surgery is satisfatory in treating single-segment thoracolumbar spinal tuberculosis with less complications.

Early passive range of motion (ROM) following arthroscopic cuff repair is thought to decrease postoperative stiffness and improve functionality. However, early aggressive rehabilitation may compromise repair integrity. Our purpose was to perform a systematic review to determine if there are differences between early and delayed rehabilitation after arthroscopic rotator cuff repair in terms of clinical outcomes and healing. We performed a literature search with the terms 'arthroscopic rotator cuff', 'immobilization', 'early', 'delayed', 'late', and 'rehabilitation' using PubMed, Cochrane Central Register of Controlled Trials, and EMBASE. Selection criteria included: level I/II evidence ≤ 6 months in duration, comparing early versus delayed rehabilitation following arthroscopic repair. Data regarding demographics, sample sizes, duration, cuff pathology, surgery, rehabilitation, functional outcomes, pain, ROM and anatomic assessment of healing were analyzed. PRIMSA criteria were followed. We identified six articles matching our criteria. Three reported significantly increased functional scores within the first 3-6 months with early rehabilitation compared to the delayed group, only one of which continued to observe a difference at a final follow-up of 15 months. Four articles showed improved ROM in the first 3-6 months post-operatively with early rehabilitation. One noted transient differences in pain scores. Only one study noted significant differences in ROM at final follow-up. No study reported any significant difference in rates of rotator cuff re-tear. However, two studies noted a trend towards increased re-tear with early rehabilitation that did not reach significance. This was more pronounced in studies including medium-large tears. Early rehabilitation after arthroscopic cuff repair is associated with some initial improvements in ROM and function. Ultimately, similar clinical and anatomical outcomes between groups existed at 1 year. While there was no significant difference between groups in anatomic failure of the repaired cuff, there may be a trend towards increased re-tear with larger tears.

To identify and compare levels of distress and sources of problems among patients with breast cancer in early survivorship. Descriptive, cross-sectional. A National Cancer Institute-designated comprehensive cancer center. 100 breast cancer survivors were selected to represent four time points in the cancer trajectory. Distress was self-reported using the Distress Thermometer and its 38-item problem list. Analysis of variance and chi-square analyses were performed as appropriate. Distress scores, problem reports, and time groups. Participants scored in range of the cutoff of more than 4 (range = 4.1-5.1) from treatment through three months post-treatment. At six months post-treatment, distress levels were significantly lower. Significant differences were found between groups on the total problem list score (p = 0.007) and emotional (p = 0.01) and physical subscale scores (p = 0.003). Comparison of groups at different points in the cancer trajectory found similar elevated levels from diagnosis through three months. Distress remained elevated in early survivorship but significantly decreased at six months post-treatment. Interventions to reduce or prevent distress may improve outcomes in early survivorship.

To compare the effectiveness of suspension fixation plus hinged external fixator with double plate internal fixation in the treatment of type C humeral intercondylar fractures. Between January 2014 and April 2016, 30 patients with type C (Association for the Study of Internal Fixation, AO/ASIF) humeral intercondylar fractures were treated. Kirschner wire suspension fixation plus hinged external fixator was used in 14 cases (group A), and double plate internal fixation in 16 cases (group B). There was no significant difference in gender, age, injury cause, disease duration, injury side, and type of fracture between 2 groups ( P >0.05). There was no significant difference in operation time and hospitalization stay between 2 groups ( P >0.05). But the intraoperative blood loss in group A was significantly less than that in group B ( P <0.05); the visual analogue scale (VAS) score at 1 day and 3 days after operation in group A were significantly less than those in group B ( P <0.05). Primary healing of incision was obtained in all patients of 2 groups, and no surgery-related complications occurred. The patients were followed up 6-24 months (mean, 12.3 months) in group A and 6-24 months (mean, 12.8 months) in group B. The self-evaluation satisfaction rate was 85.7% (12/14) in group A and was 81.2% (13/16) in group B at 3 months after operation, showing no significant difference ( χ 2 =0.055, P =0.990). Based on the improved Gassebaum elbow performance score at 6 months after operation, excellent and good rate of the elbow function was 78.6% (excellent in 5 cases, good in 6 cases, fair in 2 cases, and poor in 1 case) in group A and was 81.2% (excellent in 6 cases, good in 7 cases, fair in 2 cases, and poor in 1 case) in group B, showing no significant difference between 2 groups ( χ 2 =0.056, P =0.990). Heterotopic ossification occurred at 3 months after operation in 1 case of each group respectively. The X-ray films showed bony union in all cases; no loosening or breakage of screw was observed. The bone union time showed no significant difference between 2 groups ( t =-0.028, P =0.978). The time of internal fixation removal, the intraoperative blood loss, and VAS score at 1 day and 3 days after operation in group A were significant better than those in group B ( P <0.05). The suspension fixation plus hinged external fixator and double plate internal fixation for the treatment of type C humeral intercondylar fractures have ideal outcome in elbow function. But the suspension fixation plus hinged external fixator is better than double plate internal fixation in intraoperative blood loss, postoperative VAS score, and time of internal fixation removal.

The present study was conducted to evaluate the effect of exogenous melatonin under different photoperiods on oxidative status in Chhotanagpuri ewe. A total of 42 non-pregnant, non-lactating Chhotanagpuri ewe, having body weight ranging between 14.11±0.09 and 15.38±0.06 kg, were selected and were isolated from rams 2 months before melatonin administration. The selected animals were allocated randomly into seven groups, namely, Group I (normal control), Group II (long day [LD] control), Group III (LD+melatonin administration orally, 3 mg/day), Group IV (LD+melatonin administration subcutaneously, 1 mg/day), Group V (short day [SD] control), Group VI (SD+melatonin administration orally, 3 mg/day), and Group VII (SD+melatonin administration subcutaneously, 1 mg/day) comprising six animals in each group. Rams were then introduced into each group after completion of exogenous administration of melatonin. Blood samples with anticoagulant in vials were collected from each animal day before the start of the experiment and thereafter every month up to 5 th month. Hemolysate was prepared for estimation of oxidative stress parameters such as malondialdehyde (MDA), superoxide dismutase (SOD), and catalase (CAT). It was observed that the level of MDA was significantly (p<0.05) higher in LD groups (Group II, III and IV) in comparison to control and SD groups (VI and VII) at 1 st month. MDA concentration after exogenous administration of melatonin was significantly (p<0.05) decreased in Group IV and VI in comparison to 1 st month. SOD was significantly (p<0.05) higher in SD groups (V, VI, and VII) at the 1 st month in comparison to 0 day. After exogenous administration of melatonin, SOD concentration was significantly (p<0.05) higher in Groups III and IV in comparison to 1 st month. CAT was significantly (p<0.05) higher in SD groups (V, VI, and VII) in comparison to control and LD groups. After exogenous administration of melatonin, CAT concentration was significantly (p<0.05) higher in Groups III, IV, VI, and VIII in comparison to Groups I, II, and V. At the 3 rd month, CAT concentration significantly (p<0.05) decreased in Groups III, IV, VI, and VII in comparison to 2 nd month of experiment. However, a decreasing trend of CAT was observed in all the groups from 3 rd to 5 th month. The present experiment revealed that exogenous melatonin was able to reduce significantly the level of MDA and increased the activity of SOD and CAT in Chhotanagpuri ewe.

To investigate the therapeutic effect and biological changes of hepatic arterial infusion of p53 gene by the percutaneous port catheter system on advanced hepatocellular carcinoma (HCC) through a prospective randomized trial. A total of 48 patients with advanced HCC between May 2005 and January 2009 were divided into the treatment group (30) and the control group (18). The port catheter system was implanted through the right external iliac artery approach in all the cases; the target artery was determined according to the manifestation of the angiograph. The patients in the treatment group were given arterial infusion of p53 gene (Gendicine, Shenzhen Sibiono GeneTech Co, Ltd) with Gendicine (10vp) combined with hydroxycamptothecin (20 mg), once a week, for a course continuously for 3 weeks. The arterial infusion with hydroxycamptothecin (20 mg) was given to the patients in the control group. Pretreatment/posttreatment a fetus protein and Karnofsky Performance Status values, change of tumor according to Response Evaluation Criteria in Solid Tumors (RECIST), and the survival time were analyzed. Pretreatment/posttreatment expression of mutant p53 gene and spontaneous micronucleus formation in the peripheral blood were evaluated by flow cytometry and micronucleus test in vivo. The patients in the treatment group received 1 to 8 courses of treatment, in which the differences between pretreatment/posttreatment AFP and KPS values were significant (P < 0.05), whereas there was no significant difference (P > 0.05) between pretreatment/posttreatment AFP and KPS values within the control group. After 1 month, the survival rates of the treatment and control groups (96.6% and 94.4%, respectively) and changes in the tumor evaluated according to RECIST were significantly different (P < 0.05) between the 2 groups. After 3 months, the survival rates of the treatment and control groups (83.3% and 55.6%, respectively) and changes in the tumor were also significantly different between the 2 groups (P < 0.05). After 6 months, the survival rates (50% and 11%, respectively) and changes in the tumor were significantly different between the 2 groups (P < 0.05). After 9 months, the survival rates (23.3% and 0%, respectively) and changes in the tumor were significantly different between the 2 groups (P < 0.05). Finally, after 12 months, the survival rates (6.67% and 0%, respectively) and changes in the tumor were significantly different between the 2 groups (P < 0.05). The difference between the pretreatment and posttreatment mean rates of p53 expression in patients in the treatment group was very significant (P < 0.01). The difference between the posttreatment mean rates of the treatment group and the control group was also significant. Sequential therapy of p53 gene transcatheter arterial infusion was safe and could prolong the survival time of the patients. The biological study will play a positive role in guiding and monitoring the aspects of dosage selection and judgment of therapeutic efficacy.

Aim: The evaluation of the uterine artery recanalization rate and color Doppler parameters during follow-up after bilateral uterine artery ligation (BUAL) for postpartum hemorrhage (PPH) related to uterine atony. Material and method: A total of 40 female patients who underwent BUAL for PPH related to uterine atony and 96 females who gave birth without complication at Hatay Obstetrics and Gynecology Hospital between January 2009 and December 2012 (48 months) were included in the study. The patients’ uterine artery recanalization rate and all subjects’ color Doppler ultrasonographic parameters (PI, RI, PSV and EDV) were evaluated at the 6th and 12th months. Result: No statistically significant difference was found between the age, obstetric history (gravida and parity), BMI, type of delivery, birth weight and gestational age when the demographic data of the groups were evaluated. The patient group UtA recanalization rate was 32.5% and 37.5% for the left and right UtA respectively at the 12-month follow-up. No statistically significant difference was found in the comparison of 6- and 12-month right and left uterine artery diameters and color doppler parameters of the patient group (UtA diameters P=0.322 and P=0.787, RI index P=0.390 and P=0.094, PI index P=0.949 and P=0.374, PSV P=0.335 and P=0.085, EDV P=0.173 and P=0.418, respectively). However, right and left ovarian volume was found to significantly increase during follow-up in patient group (P<0.001 for both right and left ovary). On the other hand, a statistically significant difference was found between the patient group and the control group in the comparison of the 6- and 12-month right and left uterine artery values (6th month; P<0.001 for both UtA diameters, RI, PI, PSV, EDV; 12th month; P<0.001 for right UtA diameter, RI, PI, PSV, EDV and P=0.002 for left UtA diameter). A statistically significant difference was found only in right ovary volume in the 6th month evaluation of the patient and control group ovary volumes (P=0.011). Discussion: The recanalization rate and isolated uterine blood supply during low-term follow-up are low following the BUAL technique. The evaluation of future fertility results will be helpful in determining the reliability of this procedure in a definite manner. PMID:26221335

To evaluate the retention rates of a resin based colour changing fissure sealant (Helioseal Clear Chroma; Ivoclar Vivadent AG Schaan, Liechtenstein) compared with a coloured resin based fluoride fissure sealant (Delton FS(+); Dentsply De Trey GmbH,Konstanz,Germany). The fissure sealants (FS) were placed on all 4 caries-free first permanent molars of 31 children aged 6-9 years, using a half mouth experimental design by a paediatric dentist according to the manufacturers' instructions. A total of 121 FS were placed at baseline. Teeth were evaluated at 3 month intervals for 36 months where a preventive program including topical fluoride application was applied. Retention rates for 36 months showed a differences between Delton FS(+) and Helioseal Clear Chroma that were statistically significant (p<0.05). Delton FS(+) had total retention rate of 30.4% for 36 months compared with Helioseal Clear Chroma at 10.8% for the same evaluation period. Although Delton FS(+) showed significantly better results than Helioseal Clear Chroma for the evaluation periods, there were no statistically significant differences between Delton FS(+) (90.7%) and Helioseal Clear Chroma (80.4%) with respect to caries incidence at 36 months(p>0.05). Delton FS(+) showed a better complete retention rate for occlusal FS at one year. Both FS were aesthetically acceptable and easy to see during application and follow-up periods and gave significant protection from occlusal decay.

Patients undergoing corneal transplantation often suffer from postoperative reduced vision due to high astigmatism. This retrospective study analyzed the influence of heterotopic or orthotopic transplantation on astigmatism and visual outcome. In this study 373 eyes of 334 patients were analyzed. Group 1 (OT) contained 186 eyes, which underwent orthotopic transplantation (side of recipient and donor corresponded), whereas group 2 (HT) included 187 heterotopic keratoplasties (donor cornea placed in the recipient's contralateral side). After 1, 3, 6, 12 and 24 months the median of keratometric astigmatism, objective astigmatism, topographic astigmatism and best corrected visual acuity (BCVA) were assessed and compared between groups. The long-term results showed no statistically significant differences regarding keratometric and objective astigmatism, whereas topographic astigmatism differed significantly (p = 0.04) after 3 months. We observed a lower astigmatism of 5.7 dpt (range 3.08-7.78 dpt) in group OT than in the group HT with 7.1 dpt (range 3.9-10.7 dpt). No differences were found at the other time points. The BCVA showed a significantly better effect after 1 month (p = 0.01) in the OT group of 0.2 (0.1-0.3) than in HT group of 0.1 (0.05/0.25). In the postoperative course no additional significant dissimilarities were documented. Heterotopic and orthotopic keratoplasty show no significant long-term differences in astigmatism and visual outcom.

It has been proven that bariatric surgery affects weight loss. Patients with morbid obesity have a significantly lower quality of life (QOL) and body image compared with the general population. To evaluate QOL, body image, and general self-efficacy (GSE) in patients with morbid obesity undergoing bariatric surgery within clinical parameters. Monocentric, prospective, longitudinal cohort study. Patients completed the short form 36 (SF-36) for QOL, body image questionnaire, and GSE scale 3 times: before surgery and within 6 months and 24 months after surgery. Influence of gender, age, and type of procedure, either laparoscopic sleeve gastrectomy (SG) or laparoscopic Roux-en-Y gastric bypass, were analyzed. Thirty patients completed the questionnaires before and within 6 and 24 months after surgery. SF-36 physical summary score improved significantly from 34.3±11.0 before surgery to 46.0±10.4 within 6 months (P<.001) and to 49.8±8.2 within 24 months (P<.001) after surgery. SF-36 mental summary score improved significantly from 42.1±14.7 before surgery to 52.3±8.4 within 6 months (P<.001) and to 48.4±12.2 within 24 months (P<.001) after surgery. There were no significant differences between gender, age, and type of operation. Body image and GSE improved significantly after bariatric surgery (P<.001), and both correlated to the SF-36 mental summary score. QOL, body image, and GSE improved significantly within 6 months and remained stable within 24 months after bariatric surgery. Improvements were independent of gender, age, and type of operation. Mental QOL was influenced by body image and GSE. Copyright © 2017 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.

To compare the effect of femtosecond thinflap LASIK and photorefractive keratectomy (PRK) on postoperative endothelial cell density. In a prospective, randomized, contralateral, single-center clinical trial, 25 patients (mean age: 30+/-5 years [range: 21 to 38 years]) underwent PRK in one eye and thin-flap LASIK in the fellow eye for the correction of myopia using a wavefront-guided platform. The central corneal endothelial cell density was measured using the NIDEK Confoscan 4 preoperatively, and at 1 and 3 months postoperatively. Changes in endothelial cell density were analyzed over time between the two refractive techniques. In PRK, the average preoperative endothelial cell density was 3011+/-329 cells/mm(2), which decreased to 2951+/-327 cells/mm(2) at 1 month (P=.5736) and 2982+/-365 cells/mm(2) at 3 months (P=.6513). In thinflap LASIK, the average preoperative endothelial cell density was 2995+/-325 cells/mm(2), which decreased to 2977+/-358 cells/mm(2) at 1 month (P=.5756) and 2931+/-369 cells/mm(2) at 3 months (P=.4106). No statistically significant difference was found between the two groups at 1 (P=.7404) or 3 (P=.3208) months postoperatively. No statistically significant change was noted in endothelial cell density following either PRK or thin-flap LASIK for the treatment of myopia. Furthermore, no statistically significant difference was found between the two groups out to 3 months postoperatively, indicating that thin-flap LASIK is as safe as PRK with regards to endothelial health.

Consistent reports are not available on the effects of dioxin-like polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins (PCDD)/ polychlorinated dibenzofurans (PCDF) (dioxin-like compounds [DLCs]) on child neurodevelopment. Further, the effect of background-level exposure to individual DLC isomers is not known. We carried out the Sapporo cohort study to evaluate the effect of prenatal exposure to each DLC isomer on child neurodevelopment at 6 and 18 months of age, and assessed sex-specific differences in these effects. The levels of all and each individual DLC isomers were estimated in maternal peripheral blood. Neurodevelopment was evaluated using the Bayley Scales of Infant Development-2nd Edition for 6-month-old infants (n = 190) and 18-month-old children (n = 121). In male children, levels of 10 DLC isomers were significantly negatively associated with the Psychomotor Developmental Index (PDI) at 6 months of age after adjustment for potential confounding variables. However, at 18 months of age, these associations were absent. In female children, the level of only one DLC isomer was significantly negatively associated with PDI at 6 months of age. However, in contrast to the male children, the levels of six DLC isomers in 18-month-old female children were significantly positively associated with the Mental Developmental Index. These findings indicate that adverse neurodevelopmental effects of prenatal background-level exposure to DLCs may be stronger in male children. Copyright © 2017 Elsevier Inc. All rights reserved.

In a double blind design, 1520 children aged < 10 years were individually randomised in vitamin A and placebo group in slums of Chandigarh. Children > 12, 6-12 and < 6 months of age received 200,000, 100,000, 500,000 I.U. of vitamin A respectively every 4 to 6 months during 15 months trial period. The prevalence of vitamin A deficiency was significantly reduced in vitamin A compared to placebo group during the follow-up period. In vitamin A group, incidence of diarrhoea and measles was significantly reduced but incidence of acute respiratory infections was not significantly different compared to control group. Risk of death was also significantly less in vitamin A group. Therefore, promotion of vitamin A rich diet or supplementation with synthetic vitamin A at 4-6 month interval should be a priority in populations where risk of vitamin A deficiency is high.

Background In western populations irritable bowel syndrome (IBS) affects between 10% and 30% of the population and has a significant effect on quality of life. It generates a substantial workload in both primary and secondary care and has significant cost implications. Gut-directed hypnotherapy has been demonstrated to alleviate symptoms and improve quality of life but has not been assessed outside of secondary and tertiary referral centres. Aim To assess the effectiveness of gut-directed hypnotherapy as a complementary therapy in the management of IBS. Design of study Randomised controlled trial. Setting Primary care patients aged 18–65 years inclusive, with a diagnosis of IBS of greater than 6 weeks' duration and having failed conventional management, located in South Staffordshire and North Birmingham, UK. Method Intervention patients received five sessions of hypnotherapy in addition to their usual management. Control patients received usual management alone. Data regarding symptoms and quality of life were collected at baseline and again 3, 6, and 12 months post-randomisation. Results Both groups demonstrated a significant improvement in all symptom dimensions and quality of life over 12 months. At 3 months the intervention group had significantly greater improvements in pain, diarrhoea and overall symptom scores (P<0.05). No significant differences between groups in quality of life were identified. No differences were maintained over time. Intervention patients, however, were significantly less likely to require medication, and the majority described an improvement in their condition. Conclusions Gut-directed hypnotherapy benefits patients via symptom reduction and reduced medication usage, although the lack of significant difference between groups beyond 3 months prohibits its general introduction without additional evidence. A large trial incorporating robust economic analysis is, therefore, urgently recommended. PMID:16464325

PURPOSE To examined the effect of exercise training over 10 months at 2 levels of energy expenditure on energy and macronutrient intake in a sample of previously sedentary, overweight/obese young adults. METHODS We conducted a 10 month trial in 141 young adults who were randomized to supervised exercise, 5 days•wk−1 at 400 and 600 kcal•session−1, or non-exercise control. Participants were instructed to maintain their usual ad-libitum diets. Energy/macronutrient intake was assessed at baseline, 3.5, 7 and 10 months over 7-day periods of ad libitum eating in a university cafeteria using digital photography. Foods consumed outside the cafeteria were assessed using multiple-pass recalls. RESULTS There were no significant between group differences in absolute energy intake at baseline or any other time point in the total sample or in men. In women, absolute energy intake was significantly greater in the 600 kcal•session−1 group vs. controls at both 3.5 and 7 months. There were no significant between group differences in relative energy intake (kcal•kg•d−1) at any time point in the total sample, men or women. There were no significant within or between group differences of change in absolute or relative energy intake in any of the 3 study groups in the total sample, or in men or women. No clinically relevant changes in macronutrient intake were observed. CONCLUSION Aerobic exercise training does not significantly alter energy or macronutrient intake in overweight and obese young adults. The possibility of a threshold level beyond which increased exercise energy expenditure fails to produce a more negative energy balance, and potential sex differences in the energy intake response to increased levels of exercise are potentially important.

To establish an interference mode of group counseling for diabetic patients with depression and to evaluate the effectiveness of this mode on depression, treatment compliance and blood sugar level in the patients.
 One hundred diabetic patients with depression were randomly divided into a counseling group and a control group (n=50 per group). Self-Rating Depression Scale (SDS) was applied to all the patients. The interference mode of group counseling was established through literature review, expert consultation or interview. The counseling group received counseling for 8 times within 2 months.
 There was a significant difference in the SDS scores at 0, 3, 6 or 12 months after the intervention between the 2 groups (P<0.001). For the counseling group, there was a significant difference in the SDS scores between pre-intervention and 3, 6 or 12 months after intervention (P<0.001). However, there was no significant difference in the SDS scores between any two time points after the intervention (P>0.05). There was a significant difference in the compliance between any two time points after the intervention (P<0.05). Fasting blood glucose (FBG), 2 h postprandial blood glucose (2hPG) or glycosylated hemoglobin (HbA1c) was significantly different at any two time points after the intervention (P<0.05).
 Group counseling can improve depression, compliance and blood sugar control in the diabetic patients.

Adherence to a Mediterranean diet (MedDiet) is thought to be achievable in non-Mediterranean regions, but this has yet to be investigated. We aimed to determine if an older Australian population could adhere to a MedDiet for six months. We conducted a randomised, parallel dietary intervention trial with two dietary arms: the Mediterranean diet (MedDiet) group and the habitual diet (HabDiet) control group. A 15-point Mediterranean diet adherence score and food and nutrient intakes were estimated from three-day weighed food records collected at baseline, two and four months. Erythrocyte fatty acids, serum carotenoids and urinary metabolites were assessed at baseline, three and six months. We enrolled 166 participants; 152 commenced and 137 completed the study (70 in the MedDiet group, 67 in the HabDiet group). Adherence scores were significantly higher in the MedDiet group at two months (between group difference 2.2, 95% CI 1.3, 2.9) and four months (between group difference 2.6, 95% CI 1.9, 3.3). Consumption of vegetables, fruits, fish, legumes, nuts and olive oil significantly increased in the MedDiet group compared to the control, and discretionary food intake decreased (p < 0.01). Measures of compliance including serum β-carotene, lycopene and erythrocyte monounsaturated fatty acids were significantly higher in the MedDiet group at three and six months (p < 0.05). Our results indicate that a population of older Australians can adopt a Mediterranean diet over a six month period. PMID:28538676

To compare plasma levels of amino acids and clinical chemistry parameters in healthy infants at 1 and 4 months of age and to establish corresponding reference limits. Data of three multicenter studies assessing the safety of new infant formulas were used. During these studies infants of both age-groups were either breast-fed or received formulas of low or high protein content. All samples were analyzed centrally in the same accredited laboratory. Plasma was collected from 521 infants in total, 157 boys and 135 girls aged 1 month and 121 boys and 108 girls aged 4 months. At the age of 1 month, 62 infants had received exclusively breast milk, 198 exclusively formula, and 27 both; in the 4-months age group corresponding numbers were 49, 158 and 18, respectively; for 9 infants, diet was unknown. Concentrations of most amino acids and clinical chemistry parameters differed significantly between both ages. Regardless of age, most plasma amino acid levels were comparable or lower in breast-fed than in formula-fed infants whereas at 1 month of age most clinical chemistry parameters were higher. While in breast-fed infants the plasma urea concentration decreased over 4 months of age, it increased in formula-fed infants. There were significant differences between infants fed a low and high protein formula. At both ages, high protein formulas resulted in significantly higher threonine, 2-aminobutyrate, and urea concentrations. For clinical use, age- and diet specific reference limits in infants are warranted.

Studies of cognition after LVAD surgery have produced mixed results. To explore whether cognition would improve, decline, or remain stable after LVAD surgery, we examined cognition before and 1- and 3-months after LVAD surgery. Patients with post-surgical stroke were excluded. 28 subjects (mean age = 54.31 ± 12 years) comprised an observational case series from the DuraHeart LVAS device® trial. Cognitive testing was performed at baseline, 1-month, and 3-month post-surgery, and included tests of attention, memory, language, visualmotor speed (TMT) and visualconstruction. No difference in cognition was found between baseline and 1-month exams (means z score improvement = 0.06, p = 0.43) but cognition improved significantly between baseline and 3-month exams (mean z score improvement = 0.34, p < 0.00001). Examination of individual test scores found, after correction for multiple comparisons, only the TMT variable was significantly different at the 3-month exam. We found significantly improved cognition 3 months after LVAD surgery in a subset of patients without post-surgical stroke. The reasons for the lack of cognitive improvement at the 1-month post-surgical assessment may include ongoing medical and physiological disruptions in the immediate post-operative period. Further research into the sources of delayed improvement is warranted. Cognitive assessments performed immediately after surgery should be interpreted with caution because the results may not reflect longer term cognitive outcomes. LVAD patients may require additional support to successfully manage their health in the weeks immediately following surgery but assistance needs may decrease over time.

This study compares men and women with alcohol use disorders on levels and trajectories of spirituality and religiousness over 30 months while controlling for critical covariates. Men (n=92) and women (n=65) entering abstinence-based treatment were assessed for drinking behavior, spirituality, and psychosocial variables in a longitudinal panel study. Multiple regression tested for baseline differences and multi-level models tested for differences from baseline to 6 months (early recovery) and from 6 to 30 months (later recovery) in seven dimensions of spirituality/religiousness. Between baseline and 6 months, women had higher scores than men for forgiveness of others and lower scores than men for negative religious coping. Between 6 and 30 months, the acceleration of positive change in self forgiveness was significantly greater for women than men. Differences in negative religious coping and forgiveness might relate to differences in shame and guilt and their resolution by gender. Future research should examine whether gender differences in spirituality serve as an asset to women as they pursue addiction recovery. PMID:29250216

AIM This study evaluated the efficacy of a child-focused versus context-focused intervention in improving performance of functional tasks and mobility in young children with cerebral palsy. METHOD A randomized controlled trial cluster research design enrolled 128 children (49 females, 79 males; age range 12mo to 5y 11mo; mean age 3y 6mo, SD −1y 5mo) who were diagnosed with cerebral palsy. Children across levels I to V on the Gross Motor Classification System (GMFCS) were included in the study. Children were excluded if there were planned surgical or medication changes during the intervention period. Therapists from 19 children's rehabilitation centers were block randomized (by occupational therapist or physical therapist) to a treatment arm. Children from consenting families followed their therapists into their assigned group. Children received child-focused (n=71) or context-focused intervention (n=57) over 6 months, returning to their regular therapy schedule and approach between 6 and 9 months. The primary outcome measure was the Pediatric Evaluation of Disability Inventory (PEDI). Secondary outcome measures included the Gross Motor Function Measure (GMFM-66), range of motion of hip abduction, popliteal angle and ankle dorsiflexion, the Assessment of Preschool Children's Participation (APCP), and the Family Empowerment Scale (FES). Outcome evaluators were masked to group assignment and completed assessments at baseline, 6 months, and 9 months. RESULTS Ten children did not complete the full intervention, six in the child group and four in context group. GMFCS levels for children in the study were level I (n=37), level II (n=23), level III (n=21), level IV (n=21), and level V (n=26). There were no significant differences at baseline between the treatment groups for GMFCS level, parental education, or parental income. For the PEDI, there was no significant difference between the treatment groups, except for a small effect (p<0.03) on the Caregiver Assistance Mobility subscale between baseline and 9 months. The mean scores of both groups changed significantly on the Functional Skills Scales (p<0.001) and Caregiver Assistance Scales (p<0.02) of the PEDI after the 6-month intervention. There was no additional statistically significant change on the PEDI during the follow-up period from 6 to 9 months. A subgroup effect was found for age (p<0.001), with children younger than 3 years changing significantly more than older children. GMFCS level at baseline did not influence the amount of change on the PEDI scales. There were no significant differences between the treatment groups on the GMFM, range of motion measures, APCP or FES assessments. For the GMFM, there was a significant change over time from baseline to 6 months (p<0.001) and no significant change between 6 and 9 months. There was no adverse side effect as range of motion did not decrease in either group. Hip abduction increased significantly (p<0.01) at the 9-month assessment for both groups. For the APCP, significant changes for both treatment groups were found between baseline and 6 months for play intensity (p<0.04), physical activity intensity and diversity (p<0.001), and total score intensity (p<0.01). INTERPRETATION This study shows that child- or context-focused therapy approaches are equally effective and that frequency of intervention may be a critical component of successful intervention. Further evaluation is required to identify the various `dose-response' relations of amount of treatment and changes in functional abilities. PMID:21569012

Objective: To evaluate the changes of corneal transparency over the 1-year period after small incision lenticule extraction (SMILE) according to corneal Scheimpflug densitometry. Methods: Prospective cohort study. Fifty-five patients (100 eyes) with myopia (19 male and 36 female, aged 18 to 39 years with average of 24) who underwent SMILE and regular follow-up for at least 1 year at Tianjin Eye Hospital were enrolled. Examinations took place before SMILE and postoperatively at 1 day, 1 week, and 1, 3, 6, and 12 months. The preoperative spherical equivalent of surgical refractive correction was (-5.75±1.64) D. Corneal densitometry (CD) data were calculated automatically by the Pentacam Scheimpflug system and expressed in gray scale units (GSU), from 0 (completely transparent) to 100 (completely opaque). During the analysis of corneal densitometry, the average corneal optical density of three concentric radial zones centered on the apex of the cornea ≤2 mm, >2 mm and ≤6 mm, >6 mm and ≤10 mm diameter) were applied, and three layers were defined according to different corneal depths (the anterior 120 μm as 1st layer, and the posterior 60 μm as 3rd layer, and the center part between them of the cornea as 2nd layer). The automatic release mode was applied in order to avoid operator-induced errors. The preoperative and postoperative values in different corneal layers and different concentric radial zones were compared using Kruskal-Wallis. Results: Ninty-three eyes(93%) of all eyes achieved uncorrected distance visual acuity (UCVA) of 0.8 or better on the first day postoperatively, and 96% (96 of 100 eyes) achieved UCVA of 0.8 or better in the first week postoperatevely, and all eyes 100% (100 of 100 eyes) achieved UCVA 0.8 or better until the end of our follow-up (in 1 year postoperatively). In general, the difference preoperative and postoperative corneal average optical density is of no statistical significance (χ(2)=8.446, P =0.207), specifically, the overall postoperative CD increased in the first week after surgery (1 day to 15.90, 1 week to 15.65), and then decreased to the equivalent of baseline levels and maintained such level until 6 months after surgery (1 month to 15.60; 3 month to 15.50, 6 month to 15.55), though at the 12-month follow-up, densitometry values had spiked significantly again (12 month, 15.90). The difference between the preoperative and postoperative CD values in the central two zones (≤2 mm, >2 mm and ≤6 mm), but not the outer (>6 mm and ≤10 mm), were of statistical significance (χ(2)=61.961, 52.397, P< 0.000). When subdivided by corneal layer, significant changes in CD were detected in the anterior 120 μm layer (χ(2)=27.774, P< 0.000). The CD increased significantly (i.e., corneal transparency decreased) as compared to the preoperative baseline on the first postoperative day, and lasted through the first week. There were no significant changes in the CD of the central layer (χ(2)=0.918, P =0.986). Significant increases in the posterior 60 μm of the cornea after surgery were found only at the 6-month and 1-year follow-up examinations (χ(2)=17.469, P= 0.008). No correlation was found in the preoperative refractive error, ablation depth, postoperative UCVA and the CD. The CD at 6 months was found negatively correlated with SE at 6 months ( r= -0.219, P =0.028). Conclusions: SMILE reduced corneal transparency temporarily and primarily within the surgically altered area, however such change has no significant correlation with the ablation depth, SE, and the postoperative UCVA. Transparency recovered within a month, but patients should be monitored for at least 1 year. (Chin J Ophthalmol, 2018, 54: 27-32) .

Objectives: To examine the effects on bone tissues of immediate implant-supported mandibular overdentures with cusped or cuspless teeth. Methods: A randomized controlled trial was conducted at the Dental Clinic, Faculty of Dentistry, Al-Azhar University, Assiut Branch, Egypt, over a 12-month period from September 2013 to September 2014. Twenty patients were treated with immediate implant-supported overdentures: one group received overdentures with cusped teeth, and the other group received overdentures with cuspless teeth. The rate of implant success was assessed clinically and radiographically at 3, 6, 9, and 12 months. The data were collected by a questionnaire, an observation checklist, and radiography. The data were then analyzed using computerized methods. Results: Overdentures with cusped teeth showed a significant improvement in the clinical criteria, including the absence of clinical implant mobility, pain, and bone resorption, while the clinical criteria for the absence of peri-implant radiolucency were insignificantly different between the 2 groups (p>0.05). There were no significant differences in the clinical evaluations for bone levels at the time of insertion or 3 months after insertions, while significant differences were found at 6, 9, and 12 months after insertion. Conclusion: Overdentures with cusped teeth supported by immediate implants were found superior regarding many clinical criteria than those cuspless counterparts. PMID:26739979

To compare the effectiveness of coracoclavicular ligament reconstruction between by using autologous plantaris tendon graft combined with hook plate fixation and allogeneic tendon graft combined with hook plate fixation for treating acromiocavicular joint dislocation. Thirty-three patients with acromioclavicular joint dislocation who accorded with the inclusion criteria between January 2013 and June 2014 were assigned into 2 groups. The patients were treated with autologous plantaris tendon graft combined with hook plate fixation in group A ( n =17), and with allogeneic tendon graft combined with hook plate fixation in group B ( n =16). Thirteen-one patients was followed up more than 12 months (15 in group A and 16 in group B). There was no significant difference in gender, age, cause of injury, sides, time between injury and surgery, and type of dislocation ( P >0.05). The assessments included operation time, hospitalization time, hospitalization expenses, shoulder range of motion, gap of acromioclavicular, Constant-Murley scores, and visual analogue scale (VAS) for pain. The operation time of group A was significantly longer than that of group B, and the hospitalization expense was significantly lower than that of group B ( P <0.05). There was no significant difference in hospitalization time ( t =1.046, P =0.316). The incisions healed by first intention, and hook plate was removed after 3 months. The mean follow-up time was 21.3 months (range, 19-34 months) in group A and was 23.7 months (range, 18-37 months) in group B. X-ray examination showed no osteolysis. There was no significant difference in gap of acromiocavicular between 2 groups at preoperation, 1 week after operation, and last follow-up ( P >0.05). No redislocation of acromioclavicular joint and rejection reaction occurred during follow-up. At last follow-up, there was no significant difference in shoulder range of motion, Constant-Murley score, and VAS score between 2 groups ( P >0.05). Coracoclavicular ligament reconstruction by autologous plantaris tendon or allogeneic tendon graft combined with hook plate fixation for the treatment of acromioclavicular joint dislocation can achieve good effectiveness. The appropriate treatment should be chosen according to the patient's economic situation.

Objectives: Implant primary stability is one of the important factors in achieving implant success. The osteotome technique may improve primary stability in patients with poor bone quality. The aim of this study was to compare implant stability using two different techniques namely osteotome versus conventional drilling in the posterior maxilla. Materials and Methods: In this controlled randomized clinical trial, 54 dental implants were placed in 32 patients; 29 implants were placed in the osteotome group and 25 in the conventional drilling group. Implant stability was assessed at four time intervals namely at baseline, one, two and three months after implant placement using resonance frequency analysis (RFA). Results: Primary stability based on implant stability quotient (ISQ) units was 71.4±7 for the osteotome group and 67.4±10 for the control group. There was no statistically significant difference between the two groups in implant stability at any of the measurement times. In each group, changes in implant stability from baseline to one month and also from two months to three months post-operatively were not significant but from one month to two months after implant placement, implant stability showed a significant increase in both groups. Conclusion: The results of this study revealed that in both techniques, good implant stability was achieved and osteotome technique did not have any advantage compared to conventional drilling in this regard.

Background Obstructive sleep apnea involves repeated nocturnal desaturation and sleep fragmentation that leads to poor sleep quality, anxiety, and depression. This study aimed to investigate short- and long-term improvements in the anxiety and depression of patients with different obstructive sleep apnea treatments. Methods This is a prospective, non-randomized hospital-based study evaluated 55 patients (46 male, 9 female) with obstructive sleep apnea. The patients were divided into three groups based on different treatment: uvulopalatopharyngoplasty group, continuous positive airway pressure group, and no treatment group (by their own decision). They completed the Beck Depression Inventory II, Beck Anxiety Inventory, and Pittsburgh Sleep Quality Index before treatment and at one and six months after treatment. Results Compared to the no treatment group, the surgery and continuous positive airway pressure groups had higher body mass index, AHI, and Epworth sleepiness scale, but no difference in Pittsburgh Sleep Quality Index, Chinese Health Questionnaire-12, Beck Depression Inventory II, and Beck Anxiety Inventory. The continuous positive airway pressure and surgery groups still had no improvements in Pittsburgh Sleep Quality Index, Chinese Health Questionnaire-12, Beck Depression Inventory II, and Beck Anxiety Inventory scores one month after treatment. At six months after treatment, the continuous positive airway pressure group had significantly decreased Pittsburgh Sleep Quality Index, Chinese Health Questionnaire-12, Beck Depression Inventory II, and Beck Anxiety Inventory, whereas the surgery group had significant difference in Beck Anxiety Inventory only and the no treatment group still had no significant difference in any of the parameters. Conclusions Continuous positive airway pressure can improve the sleep quality, quality of life, depression, and anxiety of obstructive sleep apnea patients after six months of treatment. However, surgery can significantly improve anxiety only in the same period.

The aim was to describe vitamin D status and its association with changes in PF during 12 months in Finnish community-dwelling elderly (≥65 years). Baseline serum 25-hydroxyvitamin D (25OHD) concentration was measured by enzymeimmunoassay, and participants (n=518) were divided according to 25OHD to three groups (I <50 nmol/l, II 50-74.9 nmol/l, and III ≥75 nmol/l). PF (maximal isometric extension strength of right and left knee, and time in five-repetition sit-to-stand test (5STS) and 10-m walking test) was measured at baseline and after 12 months. 25OHD deficiency (<50 nmol/l) was found in 20.5% of the participants. During a 12-month follow-up, differences in changes in knee extensor strength of right (p=0.044) and left (p=0.010) lower extremity and in 10-m walking test (p=.040) between the groups were significant. According to further pairwise comparisons these differences were between groups I and III (right knee, p=0.036; left knee, p=0.009; 10-m walk, p=0.044), with the exception of left knee extensor strength in which there were also significant difference between groups I and II (p=0.039). All significant differences in changes were in favour of group II or III. Significant differences in changes in knee extensor strengths maintained after adjustments for group (intervention/control), parathyroid hormone, and baseline level of knee extensor strength. Prospective analyses showed low 25OHD concentrations (<50 nmol/l) to be associated with deterioration in PF during 12 months compared with high 25OHD concentrations (≥75 nmol/l).

To evaluate the clinical changes in dentin of deep carious lesions in young permanent molars, following ozone application with and without the use of a remineralizing solution, using the stepwise excavation. The sample included 162 first permanent immature molars, showing deep occlusal carious cavities that were indicated for indirect pulp capping. Teeth were divided into 2 main groups according to the method of ozone treatment. Each group was further subdivided equally into test and control subgroups. Following caries excavation, color, consistency and DIAGNOdent assessments of dentin were evaluated after 6 and 12 months. Regarding dentin color and consistency, no significant differences were observed following ozone application, with and without a remineralizing solution. There were no significant differences between ozone treatment, and calcium hydroxide during the different evaluation periods, except in group I cases after 6 months, concerning the dentin color. The DIAGNOdent values were significantly reduced following ozone application, with or without a remineralizing solution, as well as between test and control cases in group I after 6 months. Ozone application through the stepwise excavation had no significant effect on dentin color and consistency in young permanent molars. DIAGNOdent was unreliable in monitoring caries activity.

Children 6 through 35 months of age are recommended to receive half the dose of influenza vaccine compared with older children and adults. This was a 6-site, randomized 2:1, double-blind study comparing full-dose (0.5 mL) trivalent inactivated influenza vaccine (TIV) with half-dose (0.25 mL) TIV in children 6 through 35 months of age. Children previously immunized with influenza vaccine (primed cohort) received 1 dose, and those with no previous influenza immunizations (naive cohort) received 2 doses of TIV. Local and systemic adverse events were recorded. Sera were collected before immunization and 1 month after last dose of TIV. Hemagglutination inhibition antibody testing was performed. Of the 243 subjects enrolled (32 primed, 211 naive), data for 232 were available for complete analysis. No significant differences in local or systemic reactions were observed. Few significant differences in immunogenicity to the 3 vaccine antigens were noted. The immune response to H1N1 was significantly higher in the full-dose group among primed subjects. In the naive cohort, the geometric mean titer for all 3 antigens after 2 doses of TIV were significantly higher in the 12 through 35 months compared with the 6 through 11 months age group. Our study confirms the safety of full-dose TIV given to children 6 through 35 months of age. An increase in antibody responses after full- versus half-dose TIV was not observed, except for H1N1 in the primed group. Larger studies are needed to clarify the potential for improved immunogenicity with higher vaccine doses. Recommending the same dose could simplify the production, storage, and administration of influenza vaccines.

To determine the differences in the visual results, pain response, biomechanical effect, quality of vision, and higher-order aberrations, among other parameters, in eyes undergoing either photorefractive keratectomy (PRK) or thin-flap LASIK/sub-Bowman keratomileusis (SBK; intended flap thickness of +/-100 microm and 8.5-mm diameter) at 1, 3, and 6 months after surgery. A contralateral eye pilot study. Fifty patients (100 eyes) were enrolled at 2 sites. The mean preoperative spherical refraction was -3.66 diopters (D) and the mean cylinder was -0.66 D for all eyes. Eyes in the PRK group underwent 8.5-mm ethanol-assisted PRK, whereas in eyes in the SBK group, an 8.5-mm, (intended) 100-microm flap was created with a 60-kHz IntraLase femtosecond laser (Advanced Medical Optics, Santa Ana, CA). All eyes underwent a customized laser ablation using an Alcon LADARVision 4000 CustomCornea excimer laser (Alcon Laboratories, Fort Worth, TX). Preoperative and postoperative tests included best spectacle-corrected visual acuity, uncorrected visual acuity (UCVA), corneal topography, wavefront aberrometry, retinal image quality, and contrast sensitivity. Patients completed subjective questionnaires at each visit. One- and 3-month UCVA results showed a statistically significant difference: SBK, 88% 20/20 or better vs. 48% 20/20 or better for PRK. At 6 months, UCVA was 94% 20/20 or better for PRK and 92% for SBK. At 1 and 3 months, the SBK group had lower higher-order aberrations (coma and spherical aberration; P

We hypothesize that the use of hyaluronic acid-carboxymethylcellulose (HACM) adhesion barrier at the neurovascular bundle may hasten the return of erectile function after robot-assisted laparoscopic prostatectomy. A retrospective review identified 462 consecutive patients who underwent a nerve-sparing prostatectomy between 2009 and 2012. The first 246 patients were administered the barrier film, while the next 216 patients, the control group, did not receive HACM. Postoperative erectile function and oncologic outcomes were compared. Independent t-test and Kaplan-Meier analysis were conducted, p < 0.05 was considered significant. The two groups were well matched, without significant differences in age, weight, operative time, prostate size, preoperative prostate-specific antigen, sexual health inventory for men (SHIM), or AUA symptom scores. The mean SHIM was significantly higher for the experimental group at 6 months (6.39 vs 4.75, p = 0.008), 9 months (7.32 vs 5.44, p = 0.006), 1 year (8.52 vs 6.90, p = 0.049), and 18 months (10.01 vs 7.60, p = 0.018). This effect was not noted beyond 18 months. A subgroup analysis of patients with initial SHIM scores 22 or greater demonstrated a higher rate of return to the preoperative SHIM score for the barrier film group, 23% vs 12% (p = 0.046). There was no significant difference in biochemical recurrence between groups, with a median follow-up duration of 18 months. HACM application at the neurovascular bundle during prostatectomy may decrease the time to return of erectile function, with improved SHIM at 6 to 18 months after surgery. This effect is more pronounced in patients with better baseline erectile function. There is no significant effect on biochemical recurrence.

Amniotic membrane (AM) is an essential tool in ocular surface reconstruction. In this study, we analyzed the differential effects of glycerol and straight storage at - 80 °C for up to 6 months on the structural, biological, and mechanical properties of amniotic membrane (AM). Human placentae of 11 different subjects were analyzed. AMs were stored at - 80 °C, either with a 1:1 mixture of Dulbecco's modified Eagle medium and glycerol (glycerol) or without any medium or additives (straight). Histological image analysis, tensile strength, cell viability, and basic fibroblast growth factor (bFGF) secretion were evaluated at 0.5, 1, 3, and 6 months. Histologically, neither glycerol nor straight storage significantly altered the epithelial or stromal structure of the AM. However, the cell number of the stroma was significantly reduced during the freezing process, independently of the storage method (p = 0.05-0.001). Tensile strength and Young's modulus were not influenced by the storage method, but longer storage periods significantly increased the tensile strength of the AMs (p = 0.028). Cell viability was higher in glycerol rather than straight AM samples for up to 3 months of storage (p = 0.047-0.03). Secretion of bFGF at 3 months of storage was significantly higher in glycerol versus straight frozen AM samples (p = 0.04). Glycerol led to higher cell viability and higher bFGF secretion for up to 3 months of AM storage. However, no significant differences between the two methods were observed at 6 months of storage at - 80 °C.

The objective of this research was to evaluate a current store brand (SB) brush head for composition/physical characteristics, Wear Index (WI), and cleaning efficacy versus the previous SB brush head refill design (SB control) and the Oral-B Precision Clean brush head (positive control, PC). This research consisted of three parts: 1) Analytical analysis using Fourier Transform Infrared (FT-IR) spectrometry to evaluate the chemical composition of the current SB brush head bristles relative to the SB control. In addition, physical parameters such as bristle count and diameter were determined. 2) Wear Index (WI) investigation to determine the Wear Index scores of in vitro-aged brush heads at four weeks (one month) and 13 weeks (three months) by a trained investigator. To "age" the brush heads, a robot system was used as a new alternative in vitro method to simulate aging by consumer use. 3) Robot testing to determine the cleaning performance of in vitro-aged brush heads, comparing one month-aged current SB brush heads with the SB control (one and three months-aged) and the PC brush heads (three months-aged) in a standardized fashion. 1) FT-IR analysis revealed that the chemical composition of the current and control SB refill brush heads is identical. In terms of physical parameters, the current SB brush head has 12% more bristles and a slightly oval brush head compared to the round brush head of the SB control. 2) Wear Index analysis showed there was no difference in the one month-aged current SB brush head versus the one month-aged SB control (1.67 vs. 1.50, p = 0.65) or versus the three months-aged PC brush head (1.67 vs. 1.50, p = 0.65). The one month-aged current SB brush head demonstrated statistically significantly less wear than the three months-aged SB control (1.67 vs. 2.67, p = 0.01). 3) Analysis of cleaning efficacy shows that the one month-aged current SB brush head had improved cleaning performance over the one month-aged SB control brush head (p < 0.05), despite no statistically significant difference in wear. Both the one month-aged current and control SB brush heads showed statistically significantly lower cleaning performance compared to the three months-aged PC brush heads (p < 0.01). While the current SB brush head showed improved cleaning over the SB control, it demonstrated significantly lower durability and cleaning in comparison to the PC brush head. Dental professionals should be aware of these differences, both in durability and in cleaning performance, when recommending brush heads to their patients.

Muscular impairment, particularly for the gluteus maximus (GM), has been observed in femoroacetabular impingement (FAI). The purpose of this study was to evaluate the tensiomyographic changes of the GM, rectus femoris (RF) and adductor longus (AL) before and after arthroscopic surgery for FAI. It was hypothesized that arthroscopic treatment of FAI would improve the preoperative muscular impairment. All patients undergoing arthroscopic treatment of FAI between January and July 2015 were approached for eligibility. Patients included had a tensiomyography (TMG) evaluation including maximal displacement (Dm) and contraction time (Tc) of these muscles in both lower extremities. TMG values between the injured and healthy sides were compared at the preoperative and post-operative (3, 6 and 12 months after surgery) periods. There were no significant differences for the RF and AL, and Dm of the GM for any of the comparisons (n.s.). However, GM Tc was significantly lower at 3 (p = 0.016), 6 (p = 0.008), and 12 (p = 0.049) months after surgery in the injured side compared to preoperatively. GM Tc of the healthy side was significantly lower than the injured side at the preoperative period (p = 0.004) and at 3 (p = 0.024) and 6 (p = 0.028) months after surgery, but these significant differences were no longer observed at 12 months after surgery (n.s.). There was a significant reduction of pain in the GM area at 1 year after surgery compared to preoperatively (p < 0.0001). Arthroscopic treatment of FAI and the subsequent rehabilitation improves contraction velocity of the GM of the injured side. Despite Tc is elevated in the GM of the injured compared to the healthy side preoperatively and at 3 and 6 months after surgery, differences in Tc between both sides are no longer significant at 12 months. Athletes with FAI participating in sports with great involvement of GM may benefit from arthroscopic treatment and its subsequent rehabilitation. TMG can be used as an objective measurement to monitor muscular improvements of the GM after surgery in these patients. II.

Photodynamic therapy (PDT) using methyl aminolevulinate (MAL) is an effective first-line treatment for actinic keratosis (AK). Erbium:yttrium-aluminium-garnet (Er:YAG) ablative fractional laser-assisted MAL-PDT (AFL-PDT) has shown significant benefit for the treatment of AK. The objectives of this study were to compare the efficacy, recurrence rate, cosmetic outcome and safety between AFL-PDT with 2 and 3 h of incubation vs. Conventional MAL-PDT in patients with facial and scalp AK. This prospective randomized trial initially enrolled 440 facial and scalp AK lesions in 93 patients. Patients were randomly assigned to AFL-PDT with a 2-h incubation time (2h-AFL-PDT), 3h-AFL-PDT and 3h-MAL-PDT. All patients underwent one session of MAL-PDT using a red light-emitting diode lamp at 37 J/cm(2) , and AFL-PDT groups were assigned to pretreatment with Er:YAG AFL. Patients were followed up at 1 week, 3 months and 12 months post treatment. Efficacy, cosmetic outcomes and adverse events were assessed. Finally, 427 facial AK lesions in 88 patients were analysed in this study. Three months after the last treatment session, 3h-AFL-PDT (91.7%) was significantly more effective than 2h-AFL-PDT (76.8%) and 3h-MAL-PDT (65.6%, P < 0.001), and differences in efficacy remained significant at the 12-month follow-up. The recurrence rate was significantly lower for 3h-AFL-PDT (7.5%) than for 3h-MAL-PDT (22.1%) at 12 months (P = 0.002);however, no significant difference was found between 2h-AFL-PDT and 3h-MAL-PDT. No significant difference was found in cosmetic outcomes or safety between the three groups. We recommend 3h-AFL-PDT rather than classic MAL-PDT or short-incubation AFL-PDT for treating AK. © 2015 European Academy of Dermatology and Venereology.

Neovascular glaucoma is a refractive glaucoma. Recently, anti-VEGF factors have been used alone or in combination for the treatment of neovascular glaucoma. However, the medium- and long-term efficacy of such drugs remains to be evaluated. This study was to determine the efficacy of intravitreal ranibizumab combined with Ahmed glaucoma valve implantation for the treatment of neovascular glaucoma. In this prospective non-randomized study, 43 neovascular glaucoma patients (43 eyes) were assigned to receive either 0.5 mg intravitreal ranibizumab for three to 14 days before Ahmed glaucoma valve implantation (injection group, n = 21) or Ahmed glaucoma valve implantation alone (control group, n = 22). The patients were followed up for six to 12 months. Differences in surgical success rate, intraocular pressure, best corrected visual acuity, anti-glaucoma medications and postoperative complications were compared between the two groups. Surgical success was defined as IOP > = 6 mm Hg and < = 21 mm Hg, with or without the use of anti-glaucoma medications, and without severe complications or reoperation. Of the 43 patients, 40 completed the 6-month follow-up and 37 completed the 1-year follow-up. Success rate was 73.7% vs. 71.4% at six months and 72.2% vs. 68.4% at 12 months in the injection group and the control group respectively. No significant difference was noted between the two groups (six months: P = 0.87, 12 months: P = 1.00). There were no significant differences in the two groups with respect to intraocular pressure, best corrected visual acuity, anti-glaucoma medications or postoperative complications at six months or 12 months. Single intravitreal ranibizumab (0.5 mg) before surgery has no significant effect on the medium- or long-term outcomes of neovascular glaucoma treated with Ahmed glaucoma valve implantation.

Our study assessed the efficacy, safety, and biocompatibility of icodextrin (I) solution compared to glucose (G) solution as the daytime dwell in continuous cycling peritoneal dialysis (CCPD). In a randomized, open, prospective, parallel group study of two year's duration, either I or G was used for the long daytime dwell in CCPD patients. The study was carried out in a university hospital and teaching hospital. Established CCPD patients and patients new to the modality were both included. Clinic visits were made at three-month intervals. In all patients, clinical data were gathered; ultrafiltration (UF) was recorded; and serum, urine, and dialysate samples and effluents were collected. Peritoneal defense characteristics and mesothelial markers were determined. Every six months, peritoneal kinetics studies were performed, and serum samples for icodextrin metabolites were taken. Thirty-eight patients (19 G, 19 I) started the study. The median follow-up was 16 months and 17 months respectively (range: 0.5 - 26 months and 3 - 26 months, respectively). Daytime UF volumes increased significantly (p < 0.001), and 24-hour UF tended to increase from baseline in the I group. Dialysate creatinine clearance increased non significantly in both groups over time. In I patients, serum disaccharides (maltose) concentration increased from 0.05+/-0.01 mg/mL [mean+/- standard error of mean (SEM)] at baseline, to an average concentration in the follow-up visits of 1.15+/- 0.04 mg/mL (p <0.001). At the same time, serum sodium levels decreased from 138.1 +/- 0.7 mmol/L to an average concentration in the follow-up visits of 135.9 +/- 0.8 mmol/L (p < 0.050). At 12 months, the serum sodium concentration increased to a non significant difference from baseline. Serum osmolality increased, but did not differ significantly from G users at any visit. During peritonitis (P), daytime dwell UF decreased significantly compared to non peritonitis (NP) episodes in G patients (p < 0.0 01), but remained stable in I patients. Total 24-hour UF also decreased in G patients (p < 0.001), but not in I patients. In these I patients, serum disaccharides increased from 0.05 +/- 0.01 mg/mL to 1.26 +/- 0.2 mg/mL during follow-up. During peritonitis, serum disaccharides concentration did not increase further (1.47 +/- 0.2 mg/mL, p= 0.56). Thirty P episodes occurred during follow-up: 16 in G patients and 14 in I patients (1 per 17.6 months and 1 per 21.9 months, respectively.) After one year, absolute number and percentage of effluent peritoneal macrophages (PM phi s) were significantly higher in I patients than in G patients. The difference in percentage persisted after two years. The phagocytic capacity of PM phi s decreased over time, resulting in a borderline significant difference for coagulase-negative staphylococci phagocytosis (p=0.005) and a significant difference for E. coli phagocytosis (p <0.05) in favor of I patients. PM phi oxidative metabolism, PM phi cytokine production, and effluent opsonic capacity remained stable over time with no difference between the groups. Mass transfer area coefficients (MTACs) and clearances were stable and appeared unaffected by G or I treatment. Effluent cancer antigen 125 (CA125) was stable in G users and tended to decrease in I users. Effluent interleukin-8 (IL-8), carboxy-terminal propeptide of type I procollagen (PICP ), and amino-terminal propeptide of type III procollagen (PIIINP) did not change over time and did not differ between the groups. The use of I for the long daytime dwell in CCPD led to an increase in total UF of at least 261 mL per day, which was maintained over at least 24 months. During I treatment, serum I metabolites increased significantly and serum sodium concentrations decreased initially. As a result, serum osmolality increased slightly. Clinical adverse effects did not accompany these findings. The UF gain in the I patients was even higher during P, without a

The purpose of the present study was to determine the effect of feeding nutrient-enriched preterm formula to preterm infants until 6 months' corrected age (CA) on growth and development in the first 18 months of life. Very low-birthweight preterm infants were fed preterm formula until term (40 weeks CA). Infants were then assigned to one of three groups and were fed term formula until 6 months' CA (group 1, n= 29); preterm formula to 3 months' CA and then term formula to 6 months' CA (group 2, n= 30); or preterm formula until 6 months' CA (group 3, n= 31). Anthropometry was performed at term, 3, 6, 9, 12, 15, and at s18 months' CA. Mental and psychomotor development were assessed using the Bayley Scales of Infant Development II at 18 months' CA. Although body weight, length, head circumference and z score for CA at term in group 3 were significantly lower than those of groups 1 and 2, growth rates of these parameters were significantly higher in group 3 up to 18 months CA', as compared to groups 1 and 2. The mental developmental index and psychomotor developmental index of the Bayley test were not significantly different between the three groups. Very low-birthweight preterm infants fed nutrient-enriched preterm formula until 6 months' CA demonstrated significantly improved growth rates for bodyweight, length and head circumference, and comparable mental and psychomotor development throughout the first 18 months of life. © 2011 The Authors.

Background Self-management is an important skill for patients with diabetes, and it involves frequent monitoring of glucose levels and behavior modification. Techniques to enhance the behavior changes of diabetic patients have been developed, such as diabetes self-management education and telehealthcare. Although the patients are engaged in self-management activities, barriers to behavior changes remain and additional work is necessary to address the impact of electronic media and telehealthcare on patient self-care behaviors. Objective The aims of this study were to (1) explore the behaviors of diabetic patients interacting with online applications, (2) determine the impact of a telehealthcare program among 7 self-care behaviors of the patients, and (3) determine the changes in glycosylated hemoglobin (HbA1c) levels. Methods A telehealthcare program was conducted to assist the patients with 7 self-care activities. The telehealthcare program lasted for 18 months and included the use of a third-generation mobile telecommunications glucometer, an online diabetes self-management system, and a teleconsultant service. We analyzed the data of 59 patients who participated in the telehealthcare program and 103 who did not. The behavioral assessments and the HbA1c data were collected and statistically analyzed to determine whether the telehealthcare services had an impact on the patients. We divided the 18-month period into 3 6-month intervals and analyzed the parameters of patients assisted by the telehealthcare service at different time points. We also compared the results of those who were assisted by the telehealthcare service with those who were not. Results There was a significant difference in monitoring blood glucose between the beginning and the end of the patient participation (P=.046) and between the overall period and the end of patient participation (P<.001). Five behaviors were significantly different between the intervention and control patients: being active (P<.001), healthy eating (P<.001), taking medication (P<.001), healthy coping (P=.02), and problem solving (P<.001). Monitoring of blood glucose was significantly different (P=.02) during the 6-12 month stage of patient participation between the intervention and control patients. A significant difference between the beginning and the 6-12 month stage of patient participation was observed for the mean value of HbA1c level (P=.02), and the differences between the overall HbA1c variability and the variability of each 6-month interval was also significant. Conclusions Telehealthcare had a positive effect on diabetic patients. This study had enhanced blood glucose monitoring, and the patients in the program showed improvements in glycemic control. The self-care behaviors affect patient outcomes, and the changes of behavior require time to show the effects. PMID:24323283

One hundred and sixty 1-month-old turkey poults were delivered to 40 households in four communities of the State of Yucatan, Mexico. The poults were divided into two populations, one vaccinated and the other non-vaccinated against avian pox. During three months, monthly visits were carried out in order to monitor the appearance of lesions suggesting avian pox in the birds delivered. Each turkey was clinically examined, searching for characteristic avian pox lesions that were classified according to the degree of severity observed. The true incidence rate and the cumulative incidence rate of avian pox were determined and the true incidence and cumulative incidence rates of mortality were determined and the relative risks calculated. The true incidence rates for avian pox in vaccinated and non-vaccinated birds were 1.5 and 1.47 respectively. The cumulative incidence rates were 0.94 and 0.90 for vaccinated and non-vaccinated birds, respectively. The comparison for the whole period between vaccinated and non-vaccinated groups did not show a significant statistical difference for mortality. However, when mortality was compared between vaccinated and non-vaccinated turkeys for each month of the study, there was a statistically significant difference for the first month (relative risk = 0.216, confidence interval 0.069 to 0.676). In addition, when the severity of pox lesions between groups was compared, statistically significant differences were found in favour of the vaccinated birds (P < 0.0001).

Background: Teachers’ self-efficacy and development may be conceptualized as their beliefs in their own ability to plan, organize and carry out activities that are required to attain educational goals. In this study, we examined the effect of different medical education training courses (six-day, one- month short- term and sixmonth long- term courses) on perceived self-efficacy and development. Methods: This before-after quasi-experimental study was performed on 39 faculty members of Tehran University of Medical Sciences who participated in faculty development courses in 2013. We used valid and reliable scales to measure their perceived self-efficacy and empowerment. Results: The results revealed a significant increase in faculty members’ perceived self-efficacy in pre and posttests in one-month and six-month courses, but no significant difference was found in the six-day course (p=0.004, p<0.001 and p=0.235, respectively). These results were the same for perceived empowerment (p<0.001, p<0.001 and p=0.716 for one-month, six-month and six-day courses, respectively). A significant difference was detected in perceived self-efficacy and participant empowerment components based on the training course (p=0.005; Wilk's Λ=0.345, Partial η2=0.413). Conclusion: This study revealed that long- term courses were more effective than the short- term ones. Thus, longitudinal courses are recommended for more effectiveness. PMID:27683643

To evaluate the effect of platelet-rich plasma (PRP) treatment on patients after blepharoplasty surgery. After undergoing blepharoplasty, 20 patients were randomly divided into two groups (n = 10 each). One was treated with autologous PRP and the other was not given any post-surgery treatment (basal group). Autologous PRP application was performed intradermically 24 h, 1 month, and 2 months post-surgery, and the outcome of the applications was assessed 1, 2, and 3 months post-surgery. The postoperative wound was assessed on a patient and observer scar assessment scale (POSAS) by patients and by an unblinded clinical observer. Statistical comparison between the two groups was analyzed by using the Mann-Whitney unpaired, two-tailed test. Significant differences were considered with P ≤ 0.05. Patient-reported data indicate that compared to the basal group, the PRP group showed no significant differences regarding pain, itching, or color, but had better values for stiffness and thickness (months 1 and 2) as well as scar irregularity (month 1). Data reported by the clinical observer showed that in comparison with the basal group, the PRP group showed no differences in vascularization or pigmentation, but had lower (better) scores regarding thickness, relief, and pliability (at all assessment times). The total assessment values from patients and the observer were significantly better for the PRP than the basal group. Autologous PRP treatment enhanced some parameters associated with healing properties, suggesting a potential therapeutic value after blepharoplasty surgery.

College-age consumers are one of the groups most highly targeted by credit card marketers. While some college students use their credit cards wisely, others are unable to control their spending. The objective of this study was to investigate differences in attitude toward credit cards and the psychological factors of self-esteem and locus of control among college students who possess one or more credit cards. Attitude was operationalized to include three underlying components: cognitive, affective, and behavioral. We separated credit users into subcategories based on amount of installment debt. Convenience users were defined as those consumers who paid the credit-card balance in full each month. Installment users were classified as consumers who carried a balance month-to-month. Convenience users were compared to mild and heavy installment users to assess significance of differences in attitudinal and psychological factors. There were no significant differences in the psychological factors across the credit-card user groups. In addition, there was a statistically significant difference on each of the attitude components (knowledge/beliefs, affect, and behavior) across user groups; convenience users, mild installment, and heavy installment users.

Silver diamine fluoride (SDF) is already proven as an antibacterial agent in vitro. Present study was formulated to compare the efficacy of SDF as an antibacterial as well as antiplaque agent in vivo with fluoride varnish and acidulated phosphate fluoride (APF) gel. Total 123 children (male = 82, female = 41) were included in the study for a period of 18 months. Children were divided into three different groups-Group 1: SDF; Group 2: fluoride varnish; and Group 3: APF gel. All subjects were evaluated via plaque score at 6 th, 12 th, and 18 th months as well as Streptococcus mutans counts in saliva at 72 h, 6 th, 12 th, and 18 th months of follow-up. Significant reduction was found in plaque score as well as S. mutans counts irrespective of group division. On intergroup comparison, no statistically significant difference was found in plaque score, but significant reduction in S. mutans counts was found in Group 1 as compared with Groups 2 and 3, while no significant difference was found between Groups 2 and 3. In vivo application of SDF on enamel significantly decreases S. mutans counts as compared to fluoride varnish and APF gel.

Storage of human milk by freezing has been recommended for long-term storage. The present study analyzed the bactericidal activity of human milk on Escherichia coli and Pseudomonas aeruginosa and determined the changes in bactericidal activity following freezing at -20°C and -80°C for 1 month and 3 months. Forty-eight milk samples were collected from 48 lactating mothers. Each sample was divided into 10 aliquots. Two of the samples were processed immediately and the others were stored at both -20°C and -80°C until analysis after 1 month and 3 months of freezing. All of the fresh milk samples showed bactericidal activity against E coli and P aeruginosa. Freezing at -20°C for 1 month did not cause statistically significant alteration in bactericidal activity (P > 0.017), whereas storage for 3 months lowered the degree of bactericidal activity significantly (P < 0.017) against E coli. Bactericidal activity was protected when the samples were stored at -80°C. There was no statistically significant difference in the bactericidal activity of human milk against E coli between freezing at -20°C and -80°C for 1 month (P > 0.017); however, when milk was stored for 3 months, -80°C was significantly more protective (P < 0.017). Freezing at -20°C and -80°C for 1 month and 3 months did not cause any significant change in bactericidal activity against P aeruginosa (P > 0.05). Storage by freezing at -80°C is more appropriate to keep bactericidal capacity of stored human milk >1 month if affordable and available, especially in intensive care settings.

Summary Background the purpose of this study is to compare the therapeutic effects of extracorporeal shock wave therapy (ESWT) to those of cryoultrasound (Cryo-US) therapy in chronic lateral epicondylitis during a 12-month period. Methods single-blinded, randomized, controlled study of 80 participants treated for chronic LE with 3 ESWT sessions at 48/72-hours intervals (n=40) or 12 Cryo-US therapy sessions (4 sessions per week) (n=40). VAS and satisfactory results, considered as the sum of excellent and good scores in the Roles and Maudsley score, were used as outcome measures at baseline and 3, 6 and 12 months post-treatment. Results the results show statistically significant differences in VAS between the two groups at 6 (p<0.001) and 12 months (p<0.001) in favour of the ESWT Group. At 12 months, a difference of more than 2 points in the VAS between the two groups is demonstrated in favour of the ESWT Group. Considering satisfactory results, significant differences between the two groups are observed at 6 (p=0.003) and 12 months (p <0.001) in favour of the ESWT Group where patients achieve a satisfactory rate over 50%. Conclusions ESWT has better clinical therapeutic results at 6- and 12-month follow-up as compared to Cryo-US therapy. Level of Evidence 1B. PMID:26605190

2005-08-01

Clinical management of tuberculosis in Russia involves lengthy hospitalizations, in contrast to the recommended strategy advocated by the World Health Organization. We used Fourier transform, spectral analysis and Student's t-test to analyse periodic and seasonal variations in admission and discharge rates for tuberculosis hospitalizations in 1999-2002, using routinely captured data from the Samara Region, Russia. Hospital admissions in colder months were significantly higher than in warmer months. The mean monthly adjusted number of admissions in colder and warmer months for all adults was 413 and 372 (P < 0.01), for unemployed adults 218 and 198 (P < 0.02) and for pensioners 104 and 82 (P < 0.05). Hospital discharges varied seasonally. Maximum differences between admissions and discharges occurred in colder months and minimum differences were observed in warmer months. As hospitalizations of tuberculosis patients in colder months fulfil an important social need, shifts to ambulatory care must be carefully managed.

Significance of interleukin 6 (IL-6) deficiency in cognitive processes was evaluated in 4- and 24-month-old C57BL/6J IL-6-deficient (IL-6 KO) and control (WT) mice in Morris water maze (MWM), holeboard test (HB) and elevated plus maze (EPM). During 3-day learning escape latency time (ELT) was longer in IL-6 KO than in WT mice, however their swimming was slower, floating longer, and path length did not differ. The comparison of ELT and the distance traveled between the first and the third learning day within each group revealed significant decrease of ELT in all groups with the highest difference in 4-month-old WT mice, and significant decrease of distance traveled only in both groups of WT mice. In a single probe trial, performed 24 h after the last learning session, there were no major differences in the absolute values of ELT, but ELT turned out to be significantly shorter in both IL-6 KO groups, when it was compared to the ELT on the last learning day, indicating on better memory retrieval. In HB test only significant increase in number of rearings in aged WT mice, and in EPM significant prolongation of open arm time and higher number of open arm entries in 4-month-old IL-6 KO mice were observed. Results of HB and EPM tests showed that alterations of learning and reference memory observed in MWM were specific to cognition. Attenuation of learning ability in young adult IL-6-deficient mice assessed in MWM suggests that physiological level of IL-6 is involved in mechanisms engaged in proper memory formation, and it may also indicate on the importance of IL-6 signaling in brain development. Maintained on similar level in both 4- and 24-month-old IL-6 KO mice learning ability and its attenuation in 24-month-old vs 4-month-old WT mice indicates on slower age-related memory decline in mice not expressing IL-6. Better performance of IL-6 KO mice in the probe trial points to their reference memory improvement and may also indicate that IL-6 plays a role in mechanism responsible for cognitive flexibility.

The purpose of this study was to clarify the prevalence and degree of root resorption induced by orthodontic treatment in association with treatment factors. The files of 243 patients (72 males and 171 females) aged 9-51 years were randomly selected from subjects treated with multi-bracket appliances. The severity of root resorption was classified into five categories on radiographs taken before and after treatment. The subjects were divided into extraction (n = 113 patients, 2805 teeth) and non-extraction (n = 130 patients, 3616 teeth) groups and surgical (n = 56 patients, 1503 teeth) and non-surgical treatment (n = 187 patients, 4918 teeth) groups. These subjects were also divided into two or three groups based on the duration of multiloop edgewise archwire (MEAW) treatment, elastic use, and total treatment time: 0 month (T1; n = 184 patients, 4831 teeth), range 1-6 months (T2; n = 37 patients, 994 teeth), more than 6 months (T3; n = 22 patients, 596 teeth); range 0-6 months (n = 114 patients, 3016 teeth) more than 6 months (n = 129 patients, 3405 teeth); range 1-30 months (n = 148 patients, 3913 teeth) and more than 30 months (n = 95 patients, 2508 teeth). The prevalence of overall and severe root resorption evaluated by the number of subjects and teeth was compared with a chi-square test. A Student's t-test for unpaired data was used to determine any statistically significant differences. The prevalence of severe root resorption based on the number of teeth was significantly higher in the group with extractions (P < 0.01). Longer use of a MEAW appliance and elastics also produced a significantly higher prevalence of root resorption (P < 0.05). On the other hand, the prevalence of severe root resorption was not significantly different between the subjects treated with or without surgery, but there was a significant increase when treatment time was prolonged (P < 0.05). A significant difference was found in the amount of root movement of the upper central incisors and the distance from their root apices to the cortical bone surface (P < 0.05). These are regarded as essential factors in the onset of root resorption. These results indicate that orthodontic treatment with extractions, long-term use of a MEAW appliance and elastics, treatment time, and distance of tooth movement are risk factors for severe root resorption.

The diel and seasonal food habits of young-of-year (YOY) and post-young-of-year (PYOY) Atlantic salmon (Salmo salar) parr were assayed over the course of 11 months in the West Brook, Massachusetts USA. Gut fullness of YOY salmon did not vary significantly among months. PYOY salmon exhibited significant seasonal differences in gut fullness, with peak fullness occurring in the spring and late fall. Significant diel differences in PYOY gut fullness occurred in June and April, with peak fullness always occurring at dawn. Prey composition varied substantially among months. Dominant prey items of PYOY salmon were baetid mayflies in June, July, and August, limnephilid caddisflies in October and November, and ephemerellid mayflies in February and April. Few differences in prey composition between PYOY and YOY salmon were observed. Fish growth was unrelated to prey availability, but gut fullness explained up to 97% of growth variation across seasons. Results suggest that spring and fall are critical periods of feeding for PYOY salmon and that diel feeding intensity shifts seasonally.

The aim of this study was to evaluate the ability of tissue polypeptide-specific antigen (TPS), carcinoembryonic antigen (CEA), and cancer antigen 15-3 (CA 15-3) to predict relapse in breast cancer patients, when the measurement of biomarkers is performed within 6 months after surgery. Four hundred and seventy-two patients with breast cancer were evaluated. TPS, CEA, and CA 15-3 were measured in months 1, 3, and 6, after surgery. Disease recurrence was recorded between 7-12 months after surgery. Disease recurrence occurred in 60 patients, while 412 patients remained in recurrence-free status. TPS levels of the recurrence group differed statistically significantly in the first and sixth month after surgery compared to recurrence-free group (p=0.0339, AUC=0.6056; p<0.0001, AUC=0.7196). CEA and CA 15-3 measurements did not achieve a statistically significant difference for any month examined. TPS level in the sixth month after surgery is the best candidate biomarker to predict disease recurrence. Copyright© 2018, International Institute of Anticancer Research (Dr. George J.

The medical records of 1067 patients with breast cancer were reviewed to evaluate the influence of delay between first symptom and first treatment upon survival. Three delay intervals were considered: <3 months; 3-6 months and >6 months. At a follow-up of 120 months, survival analyses identified a statistically significant difference (p=0.029) favoring patients with <3 months delay in the whole cohort, and in the group of women aged 50 or older (p=0.001). No differences were found when survival according to delay was considered within each clinical stage. A Cox multivariate analysis revealed that performance status, stage, age and menopausal status were significant predictors of survival for the whole group of patients. However, delay was an independent prognostic factor in patients with age greater-than-or-equal-to 50. In summary, 38/1067 patients (3.1%) could have been adversely affected by a >3 months delay between first symptom and first treatment. Better survival rate for patients with a short delay would obey to a greater number of patients in favorable stages and a higher proportion of women aged 50 or older in this group.

2016-01-01

Objective: We evaluated learning retention in interns exposed to simulation. It was hypothesized that learning would degrade after 6 months and there would be a difference in retention between interns who played a critical role versus those who did not. Methods: A total of 23 groups of 5 to 9 interns underwent a cardiac scenario twice during 1 simulation experience and again 6 months later. We captured 69 recordings (23 before debrief at baseline [PrDV], 23 after debrief at baseline [PoDV], and 23 at 6-month follow-up [FUV]). Students were assigned different roles, including the critical role of “doctor” in a blinded, haphazard fashion. At 6-month follow-up, 12 interns who played the role of doctor initially were assigned that role again, while 11 interns who played noncritical roles initially were newly assigned to doctor. All videos of intern performance were scored independently and in a blinded fashion, by 3 judges using a 15-item check list. Results: Repeated-measures analysis of variance for interns completing all 3 time points indicated a significant difference between time points (F2,22 = 112, p = .00). Contrasts showed a statistically significant difference between PrDV and PoDV (p = .00), and PrDV and FUV (p = .00), but no difference between PoDV and FUV (p = .98). This was consistent with results including all data points. Checklist scores were more than double for PoDV recordings (16) and FUV (15), compared to PrDV recordings (6.6). Follow-up scores comparing old to new doctors showed no statistically significant difference (15.4 vs 15.2 respectively, t21 = 0.26, p = .80, d = .11). Conclusions: Learning retention was maintained regardless of role. PMID:26367345

A field experiment was carried out in Hong Kong to study the patterns of recolonization and succession of subtidal macrobenthos in defaunated sediment contaminated with industrial wastes and to determine the time required for benthic recovery in the industrial-contaminated sediment. A total of 50 species was found with an average of 172 animals/tray and 24 species/tray recorded one month after deployment. Initial colonizers were predominantly polychaetes (96 animals/tray, accounting for 55.7%) and gastropods (47 animals/tray, accounting for 27.2%). Abundance of macrobenthos increased quickly to a peak (505 animals/tray) after four months, declined afterwards, and increased again till the end of the experiment. Species number peaked (57 species/tray) in the same month as abundance did, and gradually declined thereafter. Abundance, species number and diversity were significantly lower in the industrial-contaminated sediment as compared to the controls during the early successional stages, indicating the harmful effects of industrial wastes on recolonization and succession of macrobenthos. Although no significant differences in community parameters between the industrial-contaminated and the control sediments were found after eleven months, significant difference in species composition still existed after fourteen months, showing a relatively long-term impact of industrial wastes on macrobenthic community structure.

Placement of a totally implantable venous access device in children with cancer often leads to hypertrophic scars after its removal. This study investigates whether the use of silicone gel sheets has a beneficial effect on scar outcome in children with cancer. In a three-arm randomized controlled trial, the effects of use of silicone gel sheets for 2 and 6 months were assessed and compared with no intervention in children with cancer after removal of the totally implantable venous access device. Silicone gel sheets were first administered 14 days after surgery. The 1-year follow-up included measurements at seven time points. Next to scar size assessment, the modified Vancouver Scar Scale was used to assess scar outcome. Thirty-six children participated. For hypertrophy, no significant differences were found between the two intervention groups and the control group. However, at 1-year follow-up, the 2-month application group showed significantly smaller scars compared with the group receiving silicone gel sheet treatment for 6 months (p = 0.04), but not when compared with the control group (p = 0.22). Longitudinal multilevel analyses could not confirm these findings and showed no significant intervention effects on both outcomes. This study provides no strong evidence to support the use of silicone gel sheets after totally implantable venous access device removal in children with cancer. There seems to be a small benefit for scar width with application for 2 months. However, for hypertrophy, the scar outcome shows no significant difference between the control group and the 2-month and 6-month treatment groups.

To develop, pilot, and evaluate a workplace intervention to reduce sickness absence, based on a demand-control-support model of job strain. Changes in the working arrangements of hospital cleaning staff were introduced with the aim of increasing their control over work and the support received at work. The study design was quasi-experimental, with 221 cleaning staff in the intervention group and 91 catering staff in the control group. The dependent variable was the difference in percentage monthly sickness absence between the 12 months preceding and following the intervention. Differences in sickness absence between staff groups for each month after the intervention were compared with differences between staff groups for the equivalent month one year prior to it. There was a significant reduction in the difference in sickness absence rates between the intervention and control group of 2.3% in the six months after the intervention, compared to the six months before. The difference was not maintained at 12 months. These results suggest that a workplace intervention aimed at increasing control and support at work has a small effect on reducing sickness absence among hospital cleaning staff in the short term. Future research should seek to replicate this effect in larger, experimental studies, analyse postulated mediators of such theory based interventions, and develop interventions that maintain improvement.

Twenty-two children with autism spectrum disorders who had not responded to supported behaviour management strategies for severe dysomnias entered a double blind, randomised, controlled crossover trial involving 3 months of placebo versus 3 months of melatonin to a maximum dose of 10 mg. 17 children completed the study. There were no significant differences between sleep variables at baseline. Melatonin significantly improved sleep latency (by an average of 47 min) and total sleep (by an average of 52 min) compared to placebo, but not number of night wakenings. The side effect profile was low and not significantly different between the two arms.

Initiation of breast feeding and duration of any breast feeding are known to differ by ethnic group, but there are limited data on differences in exclusive breast feeding. This study aimed to determine if there are ethnic differences in the initiation and duration of any and exclusive breast feeding. Breast-feeding data were obtained from a subsample of 1365 women recruited to a multi-ethnic cohort study (Born in Bradford) between August 2008 and March 2009. Poisson regression was used to investigate the impact of socio-economic, life style and birth factors on ethnic differences in the prevalence of breast feeding. Compared with white British mothers, initiation of breast feeding was significantly higher in all ethnic groups and this persisted after adjustment for socio-economic, life style and birth factors [Pakistani: prevalence rate ratio (PRR) = 1.19 (95% confidence interval 1.10, 1.29); Other South Asian: PRR = 1.29 (1.18, 1.42); Other ethnicities: PRR = 1.33 (1.21, 1.46)]. There were no differences in exclusive breast feeding at 4 months [Pakistani: PRR = 0.77 (0.54, 1.09); Other South Asian: PRR = 1.55 (0.99, 2.43); Other ethnicities: PRR = 1.50 (0.88, 2.56)]. Any breast feeding at 4 months was significantly higher in mothers of all non-white British ethnicities [Pakistani: PRR = 1.27 (1.02, 1.58); Other South Asian: PRR = 1.99 (1.52, 2.62); Other ethnicities: 2.45 (1.86, 3.21)]. Whilst women of ethnic minority groups were significantly more likely to initiate breast feeding and continue any breast feeding for 4 months compared with white British women, the rates of exclusive breast feeding at 4 months were not significantly different once socio-economic, life style and birth factors were accounted for. © 2013 John Wiley & Sons Ltd.

Breast-feeding in Bangladesh: patterns and impact on fertility.

PubMed

Mannan, H R; Islam, M N

1995-12-01

Data from the 1989 Bangladesh Fertility Survey and actuarial life table methods are used to estimate breast feeding differences by other socioeconomic, health, and demographic characteristics. Findings indicate that the average breast feeding duration for surviving children was 28.2 months (27.1 months for urban women and 28.6 months for rural women). Breast feeding duration was longer among mothers with no schooling compared to mothers or fathers with a higher education. Older mothers had different breast feeding patterns than younger mothers. Muslim women breast fed for 28.1 months; non-Muslim women did so for 18.8 months. Working women breast fed for 19.0 months compared to 28.1 months among non-working women. Duration of breast feeding increased with increased parity. Breast feeding duration averaged 17.5 months among wives of service workers and business men, 28.3 months among wives of production workers, and 29.0 and 27.9, respectively, for wives of farmers and land-owners. Contraceptive use was unrelated to breast feeding duration. Women who possessed specific household items had a shorter breast feeding period. Women who were visited by health workers had a longer breast feeding duration. There were only marginal differences between durations by whether husbands controlled health decision making or whether there was joint decision making. Gender was unrelated to duration. Differences in the significance between variables and survival are reported. Multivariate findings among women who ceased breast feeding indicate that breast feeding had a positive significant effect on amenorrhea and directly determined both closed and open birth intervals. The effect of breast feeding on amenorrhea was stronger in the closed interval. Breast feeding explained 18.9% of variation in postpartum amenorrhea (9.8% in the current open interval). 86.9% of the variance was explained by place of residence, maternal education and age, parity, maternal work status, and every use of contraception.

To investigate differences in the number of autopsies and causes of deaths affected by spiritual factors and concentration during Ramadan and to compare the results from two cities, Ankara and Bursa. Autopsies performed in morgue departments of the Council of Forensic Medicine, Ministry of Justice, in Ankara and Bursa during Ramadan and non-Ramadan (control) months between 2003 and 2006 were retrospectively investigated for age, sex, cause of death, manner of death and blood toxicological analyses. The number of autopsies was significantly higher in Ramadan months than in the control months in Bursa, but low and insignificant in Ankara. A significant decline in traumatic deaths was observed during Ramadan (p less than 0.05). During Ramadan, while rates of homicidal deaths displayed a relatively steep decline in females, the rates of homicide were increased in males. This might be due to a decrease in natural deaths and accidents. To make further comments, conducting studies evaluating detailed socio-demographic features and assessing relevant psychological states of the victims can be beneficial.

The evaluation was done using Indonesian version of GERD questionnaire (GERD-Q) between the two groups, and between Ramadhan month and non-Ramadhan month in the Ramadhan fasting group. there was a statistically significant difference (p<0.01) in the median of GERD-Q score in Ramadhan-fasting group subjects and non-Ramadhan-fasting group subjects (0 vs. 4). Moreover, a statistically significant difference (p<0.01) was also found in the median of GERD-Q score in Ramadhan-fasting group subjects and non-fasting group subjects (p<0.01). subjects in Ramadhan fasting group, GERD symptoms experienced less severe during fasting month (Ramadhan) than non-fasting month. During Ramadhan month, GERD symptoms were also milder in Ramadhan fasting group than those in non-fasting group subjects.

This study compares the auditory perceptual skill development of 23 congenitally deaf children who received the Nucleus 22-channel cochlear implant with the SPEAK speech coding strategy, and 20 children who received the CLARION Multi-Strategy Cochlear Implant with the Continuous Interleaved Sampler (CIS) speech coding strategy. All were under 5 years old at implantation. Preimplantation, there were no significant differences between the groups in age, length of hearing aid use, or communication mode. Auditory skills were assessed at 6 months and 12 months after implantation. Postimplantation, the mean scores on all speech perception tests were higher for the Clarion group. These differences were statistically significant for the pattern perception and monosyllable subtests of the Early Speech Perception battery at 6 months, and for the Glendonald Auditory Screening Procedure at 12 months. Multiple regression analysis revealed that device type accounted for the greatest variance in performance after 12 months of implant use. We conclude that children using the CIS strategy implemented in the Clarion implant may develop better auditory perceptual skills during the first year postimplantation than children using the SPEAK strategy with the Nucleus device.

To investigate the effect of zoledronic acid (ZA) on lumbar spinal fusion in patients with osteoporosis. This retrospective study includes 94 osteoporotic patients suffering from lumbar degenerative diseases or lumbar fracture who underwent lumbar spinal fusion in our institution from January 2013 to August 2014. They were divided into ZA group and control group according to whether the patient received ZA infusion or not. The patients in ZA group were given 5 mg intravenous ZA at the 3rd-5th days after operation. All patients took daily oral supplement of 600 mg calcium carbonate and 800 IU vitamin D during the follow-up after operation. The Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), and Short Form 36 (SF-36) scores were recorded preoperatively and post-operatively to evaluate the clinic outcomes; the spinal fusion was assessed by X-ray or CT Scan. 64 patients finished the final follow-up, including 30 patients in ZA group and 34 patients in control group. No significant difference was observed in gender, age, and preoperative BMI VAS, ODI, and SF-36 scores between the two groups (P > 0.05). The post-operative VAS and ODI scores decreased rapidly at 3 and 6 months, but rose back slightly at 12 and 24 months in both groups. On the contrary, post-operative SF-36 scores increased rapidly at 3 and 6 months, while fell back slightly at 12 and 24 months, with a statistically significant difference between the two groups at 12 months, but not at 3 and 6 month post-operation. The spinal fusion rate in ZA group was 90% at 6 months, 92% at 12 months, while it was 75% at 6 months, 92.86% at 12 months in control group, significantly different between the two groups at 12 months, but not at 6 months. In the whole follow-up period, adjacent vertebral compressing fracture occurred in five patients in control group, none in ZA group. No pedicle screw loosening was observed in ZA group, with six in control group. Zoledronic acid accelerates spinal fusion, shortens the time of fusion without changing fusion rate, and also decreases the risk of adjacent vertebral compressing fracture and the rate of pedicle screw loosening, resulting in the improvement of clinical outcomes and quality of life.

The purpose of this study was to describe differences in parent input and child vocal behaviors of children with Down syndrome (DS) compared with typically developing (TD) children. The goals were to describe the language learning environments at distinctly different ages in early childhood. Nine children with DS and 9 age-matched TD children participated; 4 children in each group were ages 9-11 months, and 5 were between 25 and 54 months. Measures were derived from automated vocal analysis. A digital language processor measured the richness of the child's language environment, including number of adult words, conversational turns, and child vocalizations. Analyses indicated no significant differences in words spoken by parents of younger versus older children with DS and significantly more words spoken by parents of TD children than parents of children with DS. Differences between the DS and TD groups were observed in rates of all vocal behaviors, with no differences noted between the younger versus older children with DS, and the younger TD children did not vocalize significantly more than the younger DS children. Parents of children with DS continue to provide consistent levels of input across the early language learning years; however, child vocal behaviors remain low after the age of 24 months, suggesting the need for additional and alternative intervention approaches.

This study compared the effect of cryopreserved storage duration of wasabi shoot tips, which derived from the same in vitro mother-plant. We compared the survival of shoot tips and the genetic stability of regenerated plants originating from four experimental groups: shoot tips stored in a -150°C deep-freezer for 10 years; shoot tips stored in liquid nitrogen for 2 h; shoot tips treated with PVS2 vitrification solution; and untreated controls. No significant difference in survival was observed between the four experimental groups. Survival ranged between 93 and 100%. Genetic stability of plants regenerated from cryopreserved shoot tips was assessed over a period of 24 months using morphological, biochemical and molecular markers. While glucose, fructose and glutamic acid concentrations differed slightly between experimental groups after 16 months, these differences disappeared after 24 months. No significant differences were noted for the morphological markers studied (petiole length, shoot number and leaf index). No differences were observed in RAPD profiles obtained with the six primers tested.

The SERVE-HF trial investigated the impact of treating central sleep apnoea (CSA) with adaptive servo-ventilation (ASV) in patients with systolic heart failure. A preplanned substudy was conducted to provide insight into mechanistic changes underlying the observed effects of ASV, including assessment of changes in left ventricular function, ventricular remodelling, and cardiac, renal and inflammatory biomarkers. In a subset of the 1325 randomised patients, echocardiography, cardiac magnetic resonance imaging (cMRI) and biomarker analysis were performed at baseline, and 3 and 12 months. In secondary analyses, data for patients with baseline and 12-month values were evaluated; 312 patients participated in the substudy. The primary endpoint, change in echocardiographically determined left ventricular ejection fraction from baseline to 12 months, did not differ significantly between the ASV and the control groups. There were also no significant between-group differences for changes in left ventricular dimensions, wall thickness, diastolic function or right ventricular dimensions and ejection fraction (echocardiography), and on cMRI (in small patient numbers). Plasma N-terminal pro B-type natriuretic peptide concentration decreased in both groups, and values were similar at 12 months. There were no significant between-group differences in changes in cardiac, renal and systemic inflammation biomarkers. In patients with systolic heart failure and CSA, addition of ASV to guideline-based medical management had no statistically significant effect on cardiac structure and function, or on cardiac biomarkers, renal function and systemic inflammation over 12 months. The increased cardiovascular mortality reported in SERVE-HF may not be related to adverse remodelling or worsening heart failure. © 2017 The Authors.

The primary objective of this project was to examine the effectiveness of an Internet-based smoking cessation intervention combined with a tele-health medication clinic for nicotine replacement therapy (NRT) compared to referral to clinic-based smoking cessation care. A total of 413 patients were proactively recruited from the Durham VA Medical Center and followed for 12 months. Patients were randomized to receive either a referral to VA specialty smoking cessation care (control) or to the Internet intervention and tele-health medication clinic. Primary outcomes included (1) intervention reach, (2) self-reported 7-day point prevalence abstinence rates at 3 months and 12 months, and 3) relative cost-effectiveness. Reach of the Internet intervention and use of smoking cessation aids were significantly greater compared to the control. At 3 months-post randomization, however, there were no significant differences in quit rates: 17% (95% CI: 12%–23%) in the Internet-based intervention compared to 12% (95% CI: 8%–17%) in the control arm. Similarly, there were no differences in quit rates at 12 months (13% vs. 16%). While costs associated with the Internet arm were higher due to increased penetration and intensity of NRT use, there were no statistically significant differences in the relative cost effectiveness (e.g., life years gained, quality adjusted life years) between the two arms. Current results suggest that using an electronic medical record to identify smokers and proactively offering smoking cessation services that are consistent with US Public Health Guidelines can significantly reduce smoking in veterans. Novel interventions that increase the reach of intensive treatment are needed to maximize quit rates in this population.

Oral nutritional supplementation (ONS) was provided to ESRD patients with hypoalbuminemia as part of Fresenius Medical Care Health Plan's (FMCHP) disease management. This study evaluated the association between FMCHP's ONS program and clinical outcomes. Analyses included FMCHP patients with ONS indication (n=470) defined as 2-month mean albumin <3.8 g/dl until reaching a 3-month mean ≥3.8 g/dl from February 1, 2006 to December 31, 2008. Patients did not receive ONS if deemed inappropriate or refused. Patients on ONS were compared with patients who were not, despite meeting ONS indication. Patients with ONS indication regardless of use were compared with Medicare patients with similar serum albumin levels from the 2007 Centers for Medicare and Medicaid Services Clinical Performance Measures Project (CPM). Cox models calculated adjusted hospitalization and mortality risks at 1 year. Among patients with indication for ONS, 276 received supplements and 194 did not. ONS use was associated with 0.058 g/dl higher serum albumin overall (P=0.02); this difference decreased by 0.001 g/dl each month (P=0.05) such that the difference was 0.052 g/dl (P=0.04) in month 6 and the difference was no longer significant in month 12 . In analyses based on ONS use, ONS patients had lower hospitalization at 1 year (68.4%; P<0.01) versus patients without ONS (88.7%), but there was no significant reduction in mortality risk (P=0.29). In analyses based on ONS indication, patients with indication had lower mortality at 1 year (16.2%) compared with CPM patients (23.4%; P<0.01). These findings suggest that ONS use was associated with significantly lower hospitalization rates but had no significant effect on mortality in a disease management setting.

The objective of this randomized, controlled clinical trial was to compare the clinical and microbiological effects of pocket debridement using erbium-doped: yttrium, aluminium and garnet (Er:YAG) laser with conventional debridement in maintenance patients. Fifteen patients, all smokers, having at least four teeth with residual probing depth (PD) ≥ 5 mm were recruited. Two pockets in two jaw quadrants were randomly assigned to subgingival debridement using an Er:YAG laser (test) or ultrasonic scaler/curette (control) at 3-month intervals. Relative attachment level (RAL), PD, bleeding on probing and dental plaque were recorded at baseline and at 6 and 12 months. Microbiological subgingival samples were taken at the same time points and analysed using a checkerboard DNA-DNA hybridization technique. A significant decrease in PD took place in both treatments from baseline to 12 months (p < 0.01). In the control, the mean initial PD decreased from 5.4 to 4.0 mm at 12 months. For the test, a similar decrease occurred. No significant between-treatment differences were shown at any time point. The mean RAL showed no overall significant inter- or intra-treatment differences (p > 0.05). No significant between-treatment differences were observed in subgingival microbiological composition or total pathogens. The results failed to support that an Er:YAG laser may be superior to conventional debridement in the treatment of smokers with recurring chronic inflammation. This appears to be the first time that repeated Er-YAG laser instrumentation has been compared with mechanical instrumentation of periodontal sites with recurring chronic inflammation over a clinically relevant time period. © 2012 John Wiley & Sons A/S.

Resistance to natural infection by gastrointestinal nematodes was compared in 67 female calves of the following genetic groups: Nelore (NX); 1/2 Senepol+1/2 Nelore (SN); and 1/2 Aberdeen Angus+1/2 Nelore (AN). The NX (n=26), SN (n=23) and AN (n=18) animals were monitored for 14 months, during which they remained without treatment, allowed to graze in a tropical environment. Eggs per gram of feces (EPG), coprocultures and packed cell volume (PCV) were carried out monthly. No significant effects of the interaction between the genetic groups and month/year of collection and the genetic group on the EPG were found, but there was a significant influence of the month of collection (P<0.01). The monthly PCV measurements did not differ for the animals of the three genetic groups and there was no association found between the EPG and PCV. The animals of the SN and NX groups showed similar numbers of EPG with results zero, while for the AN group these numbers were significantly lower (P<0.05). Although the NX group had a large number of EPG with results zero, it also contained many animals with high counts, meaning this group had higher averages during the entire study period. The following nematode genera were found in the coprocultures: Haemonchus, Cooperia, Oesophagostomum and Trichostrongylus, the latter in smallest proportion. There was no significant difference between the genetic groups for averages of all parasites identified, except Cooperia, which were present in higher numbers in the animals of the NX group (P<0.05). The results obtained in this experiment suggest that the use of Bos taurus x Bos indicus crossbreeds can be a good strategy to reduce the use of chemical control in Brazil.

The aims of this study were to determine the impact of body site, vigorous brushing and topical melatonin treatment on hair regrowth after clipping normal dogs. Siberian Husky dogs were randomly assigned to three groups of eight dogs each. All dogs had the lumbosacral region and both lateral thighs clipped. The left thigh and lumbosacral area received no treatment and were compared in all 24 dogs. Eight dogs had the right thigh treated with 0.1% melatonin twice daily for 2 months, and hair regrowth was compared with the left thigh. Eight dogs had the right thigh brushed twice daily for 2 months, and hair regrowth was compared with the left thigh. Eight dogs had neither thigh treated. Hairs were plucked before and 2 months postclipping, and the proportion of hair growth from the original length was calculated and compared as described above. Biopsy samples were collected before and after treatment to determine if brushing induced dermal inflammation and melatonin increased the proportion of anagen follicles. Proportionally, left thigh hairs were significantly longer compared to lumbosacral hairs 2 months postclipping. No significant differences in hair regrowth were noted between the nontreated thigh and the thigh treated with melatonin or brushed. No significant difference in dermal inflammation was noted before and after brushing. No significant differences were observed in the proportion of anagen follicles before and after topical melatonin treatment. Our results showed that the hairs in the lumbosacral region were proportionally shorter than lateral thigh hairs 2 months postclipping. Moreover, topical melatonin and brushing had no impact on hair regrowth after clipping normal dogs.

Idiopathic pulmonary fibrosis (IPF) is a chronic, devastating, lung disease, with few therapeutic options. Data are limited with respect to the long-term effect of exercise training (ET) in IPF. This study sought to evaluate the long-term effects of a 12-week ET program on clinical outcomes in IPF patients. Thirty-four IPF patients were randomly allocated to ET or control groups. ET group participated in a 12-week supervised exercise program, while the control group continued with regular medical treatment alone. Exercise capacity, 30 s-chair-stand test for leg strength, dyspnea, and Saint George's Respiratory Questionnaire (SGRQ) for quality of life (QOL) were assessed at baseline and re-evaluated at 11 months from baseline. In addition, at 30-month time point from baseline, the impact of the 12-week intervention was analyzed with respect to survival and cardio-respiratory-related hospitalizations. Thirty-two patients completed the 12-week intervention and 28 patients (14 in each group) were re-evaluated. At 11-month follow-up, no significant differences between the groups and time effect were demonstrated for most outcomes. ET group showed preserved values at the baseline level while the control group showed a trend of deterioration. Only the 30 s-chair-stand test (mean difference 3 stands, p = 0.01) and SGRQ (mean difference -6 units, p = 0.037) were significantly different between the groups. At 30 months, the survival analysis showed three deaths, eight hospitalizations occurred in the control group versus one death, one lung transplantation and seven hospitalizations in the ET group, with no significant differences between groups. At 11-month follow-up, the 12-week ET program showed clinical outcomes were preserved at baseline levels with some maintenance of improvements in leg strength and QOL in the ET group. The control group showed a trend of deterioration in the outcomes. At 30 months, the 12-week ET program did not show benefits in prognosis although the study was underpowered to detect such differences. We suggest including ET as a long-term continued treatment and as a core component of pulmonary rehabilitation programs for IPF patients.

To quantify the psychological impact of primary care based stepwise screening for type 2 diabetes. Controlled trial and comparative study embedded in a randomised controlled trial. 15 practices (10 screening, five control) in the ADDITION (Cambridge) trial in the east of England. 7380 adults (aged 40-69) in the top fourth for risk of having undiagnosed type 2 diabetes (6416 invited for screening, 964 controls). Invited for screening for type 2 diabetes or not invited (controls), incorporating a comparative study of subgroups of screening attenders. Attenders completed questionnaires after a random blood glucose test and at 3-6 months and 12-15 months later. Controls were sent questionnaires at corresponding time points. Non-attenders were sent questionnaires at 3-6 months and 12-15 months. State anxiety (Spielberger state anxiety inventory), anxiety and depression (hospital anxiety and depression scale), worry about diabetes, and self rated health. No significant differences were found between the screening and control participants at any time-for example, difference in means (95% confidence intervals) for state anxiety after the initial blood glucose test was -0.53, -2.60 to 1.54, at 3-6 months was 1.51 (-0.17 to 3.20), and at 12-15 months was 0.57, -1.11 to 2.24. After the initial test, compared with participants who screened negative, those who screened positive reported significantly poorer general health (difference in means -0.19, -0.25 to -0.13), higher state anxiety (0.93, -0.02 to 1.88), higher depression (0.32, 0.08 to 0.56), and higher worry about diabetes (0.25, 0.09 to 0.41), although effect sizes were small. Small but significant trends were found for self rated health across the screening subgroups at 3-6 months (P=0.047) and for worry about diabetes across the screen negative groups at 3-6 months and 12-15 months (P=0.001). Screening for type 2 diabetes has limited psychological impact on patients. Implementing a national screening programme based on the stepwise screening procedure used in the ADDITION (Cambridge) trial is unlikely to have significant consequences for patients' psychological health.

The principle goal of this longitudinal study was to examine parent perceptions of home literacy environment (e.g., frequency of book reading, ease of book reading with child) and observed behaviors during shared book reading (SBR) interactions between parents and their children with hearing loss (HL) as compared with parents and their children with normal hearing (NH) across 3 time points (12, 24, and 36 months old). Relationships were also explored among home literacy environment factors and SBR behaviors and later language outcomes, across all three time points for parents of children with and without HL. Participants were a group of parents and their children with HL (N = 17) and typically developing children with NH (N = 34). Parent perceptions about the home literacy environment were captured through a questionnaire. Observed parent behaviors and their use of facilitative language techniques were coded during videotaped SBR interactions. Children's oral language skills were assessed using a standardized language measure at each time point. No significant differences emerged between groups of parents (HL and NH) in terms of perceived home literacy environment at 12 and 36 months. However, significant group differences were evident for parent perceived ease of reading to their child at 24 months. Group differences also emerged for parental SBR behaviors for literacy strategies and interactive reading at 12 months and for engagement and interactive reading at 36 months, with parents of children with HL scoring lower in all factors. No significant relationships emerged between early home literacy factors and SBR behaviors at 12 months and oral language skills at 36 months for parents of children with NH. However, significant positive relationships were evident between early home literacy environment factors at 12 months and oral language skills at 36 months for parents and their children with HL. Although both groups of parents increased their frequency of SBR behaviors over time, parents of children with HL may need additional support to optimize SBR experiences to better guide their toddlers' and preschoolers' language skills. Early intervention efforts that focus on SBR interactions that are mutually enjoyed and incorporate specific ways to encourage parent-child conversations will be essential as children with HL acquire language.

OBJECTIVE Seven cervical total disc replacement (TDR) devices have received FDA approval since 2006. These devices represent a heterogeneous assortment of implants made from various biomaterials with different biomechanical properties. The majority of these devices are composed of metallic endplates with a polymer core. In this prospective, randomized multicenter study, the authors evaluate the safety and efficacy of a metal-on-metal (MoM) TDR (Kineflex|C) versus anterior cervical discectomy and fusion (ACDF) in the treatment of single-level spondylosis with radiculopathy through a long-term (5-year) follow-up. METHODS An FDA-regulated investigational device exemption (IDE) pivotal trial was conducted at 21 centers across the United States. Standard validated outcome measures including the Neck Disability Index (NDI) and visual analog scale (VAS) for assessing pain were used. Patients were randomized to undergo TDR using the Kineflex|C cervical artificial disc or anterior cervical fusion using structural allograft and an anterior plate. Patients were evaluated preoperatively and at 6 weeks and 3, 6, 12, 24, 36, 48, and 60 months after surgery. Serum ion analysis was performed on a subset of patients randomized to receive the MoM TDR. RESULTS A total of 269 patients were enrolled and randomly assigned to undergo either TDR (136 patients) or ACDF (133 patients). There were no significant differences between the TDR and ACDF groups in terms of operative time, blood loss, or length of hospital stay. In both groups, the mean NDI scores improved significantly by 6 weeks after surgery and remained significantly improved throughout the 60-month follow-up (both p < 0.01). Similarly, VAS pain scores improved significantly by 6 weeks and remained significantly improved through the 60-month follow-up (both p < 0.01). There were no significant changes in outcomes between the 24- and 60-month follow-ups in either group. Range of motion in the TDR group decreased at 3 months but was significantly greater than the preoperative mean value at the 12- and 24-month follow-ups and remained significantly improved through the 60-month period. There were no significant differences between the 2 groups in terms of reoperation/revision surgery or device-/surgery-related adverse events. The serum ion analysis revealed cobalt and chromium levels significantly lower than the levels that merit monitoring. CONCLUSIONS Cervical TDR with an MoM device is safe and efficacious at the 5-year follow-up. These results from a prospective randomized study support that Kineflex|C TDR as a viable alternative to ACDF in appropriately selected patients with cervical radiculopathy.

The objective of this study is to compare the quality of life (QOL) outcomes between laparoscopic radical prostatectomy (LRP) and robot-assisted radical prostatectomy (RARP). Between July 2007 and July 2013, 229 patients with localized prostate cancer underwent LRP while 105 patients with localized prostate cancer underwent RARP between December 2012 and August 2014. We evaluated their QOL using the 8-item Short-Form Health Survey (SF-8) and Expanded Prostate Cancer Index of Prostate (EPIC) questionnaires at preoperative and at postoperative 3, 6 and 12 months. In the LRP and RARP groups, over 80 and 90% of patients answered questionnaires at each follow-up time, respectively. At baseline QOL of EPIC and SF-8, there was no significant difference between LRP and RARP groups. At postoperative 3 months, Physical and Mental Components of SF-8 and Urinary Summary (U), all Urinary Subscales, Sexual Function and Bowel Function of EPIC showed significantly better scores in RARP group than in LRP group. At postoperative 6 and 12 months, there were no differences between LRP and RARP groups in terms of all QOL scores. RARP group showed better scores in SF-8 as well as urinary and sexual function of EPIC at postoperative-3 months. These differences disappeared at postoperative 6 and 12 months.

Data are presented from a multi-center, prospective, longitudinal, clinical trial comparing four different treatments for periodontitis, (1) the LANAPTM protocol utilizing a FR pulsed-Nd:YAG laser; (2) flap surgery using the Modified Widman technique (MWF); (3) traditional scaling and root planing (SRP); and (4) coronal debridement (CD). Each treatment was randomized to a different quadrant. Fifty-one (54) subjects were recruited at five centers that included both private practice and university-based investigators. At 6-months and 12 months post-treatment the LANAPTM protocol and MWF yielded equivalent results based on changes in probing depths. The major difference observed between the two procedures was that patients reported significantly greater comfort following the LANAP™ procedure than following the MWF (P<0.001). There was greater reduction in bleeding in the LANAPTM quadrant than in the other three at both 6 and 12 months. Improvements following SRP were better than expected at 6 months and continued to improve, providing outcomes that were equivalent to both LANAPTM and MWF at 12 months. The improvement in the SRP quadrants suggests the hypothesis that an aspect of the LANAPTM protocol generated a significant, positive and unanticipated systemic (or trans-oral) effect on sub-gingival wound healing.

This study examines the differences in explicit and implicit stigma between medical and non-medical undergraduate students at baseline; the changes of explicit and implicit stigma in medical undergraduate and non-medical undergraduate students after a 1-month psychiatric clerkship and 1-month follow-up period; and the differences in the changes of explicit and implicit stigma between medical and non-medical undergraduate students. Seventy-two medical undergraduate students and 64 non-medical undergraduate students were enrolled. All participants were interviewed at intake and after 1 month. The Taiwanese version of the Stigma Assessment Scale and the Implicit Association Test were used to measure the participants' explicit and implicit stigma. Neither explicit nor implicit stigma differed between two groups at baseline. The medical, but not the non-medical, undergraduate students had a significant decrease in explicit stigma during the 1-month period of follow-up. Neither the medical nor the non-medical undergraduate students exhibited a significant change in implicit stigma during the one-month of follow-up, however. There was an interactive effect between group and time on explicit stigma but not on implicit stigma. Explicit but not implicit stigma toward mental illness decreased in the medical undergraduate students after a psychiatric clerkship. Further study is needed to examine how to improve implicit stigma toward mental illness.

Understanding how known eating disorder (ED) risk factors change in relating to one another over time may inform efficient intervention targets. We examined short-term (i.e., 1 month) reciprocal longitudinal relations between weight/shape concern and comorbid symptoms (i.e., depressed mood, anxiety) and behaviors (i.e., binge drinking) over the course of 24 months using cross-lagged panel models. Participants were 185 women aged 18-25 years at very high risk for ED onset, randomized to an online ED preventive intervention or waitlist control. We also tested whether relations differed based on intervention receipt. Weight/shape concern in 1 month significantly predicted depressed mood the following month; depressed mood in 1 month also predicted weight/shape concern the following month, but the effect size was smaller. Likewise, weight/shape concern in 1 month significantly predicted anxiety the following month, but the reverse was not true. Results showed no temporal relations between weight/shape concern and binge drinking in either direction. Relations between weight/shape concern, and comorbid symptoms and behaviors did not differ based on intervention receipt. Results support focusing intervention on reducing weight/shape concern over reducing comorbid constructs for efficient short-term change. Level I, evidence obtained from a properly designed randomized controlled trial.

Although diabetics may be exempted from Ramadan fasting, many patients still insist on this worship. Aim of the present study is to compare the effects of glimepiride, repaglinide, and insulin glargine in type 2 diabetics during Ramadan fasting on the glucose metabolism. Patients, who were willing to fast, were treated with glimepiride (n=21), repaglinide (n=18), and insulin glargine (n=10). Sixteen non-fasting control type 2 diabetics matched for age, sex, and body mass index were also included. Fasting blood glucose (FBG), post-prandial blood glucose (PBG), HbA1c, and fructosamine as well as lipid metabolism were evaluated in pre-Ramadan, post-Ramadan, and 1-month post-Ramadan time points. There was no significant change from pre-Ramadan in FBG, PBG, and HbA1c variables in fasting diabetics at post-Ramadan and 1-month post-Ramadan. However, PBG was found higher in non-fasting control diabetics at post-Ramadan and 1-month post-Ramadan (p<0.05 and p<0.001, respectively). In fructosamine levels, a significant increase was noted both in fasting group and non-fasting group at 1-month post-Ramadan (p<0.01 for all). However, no significant difference was found in the comparison of the changes in fructosamine levels between fasting group and non-fasting group. Risk of hypoglycemia did not significantly differ between fasting and non-fasting diabetics. There was no significant difference between three drug therapies regarding glucose metabolism and rate of hypoglycemia. No adverse effects on plasma lipids were noted in fasting diabetics. In this fasting sample of patients with type 2 diabetes, glimepiride, repaglinide, and insulin glargine did not produce significant changes in glucose and lipid parameters.

In this large randomized trial among callers to the Cancer Information Service (CIS), tailored print materials were tested for efficacy in promoting colorectal cancer (CRC) screening (fecal occult blood test [FOBT], flexible sigmoidoscopy, or colonoscopy). All participants completed baseline interviews at the end of their usual service calls to the CIS, as well as short-term (6-month) and longer-term (14-month) telephone follow-up interviews. The study sample (n = 4,014) was restricted to English-speaking CIS callers 50 + years of age, who would be eligible for CRC screening at 14 months follow-up and did not call the CIS about CRC or CRC screening. Four experimental conditions were compared: a single untailored (SU) mailout of print material (the control condition); a single tailored (ST) mailout of print material; four (multiple) tailored (MT) mailouts of print materials spanning 12 months, all of which were tailored to information obtained at baseline; and four (multiple) retailored (MRT) mailouts also spanning 12 months, with retailoring of the print materials (mailouts 2, 3, and 4) based on updated information obtained from the 6-month follow-up interviews. Consistent with the main hypothesis of this trial, a significant linear trend across the SU, ST, MT, and MRT groups was found at 14 months (42%, 44%, 51%, and 48%, respectively, p = 0.05). Only for MT was there a significant difference compared with SU (p = 0.03) for the sample as a whole, while no differences were found for MT vs. MRT at 14 months. Significant moderator effects in the predicted direction were found among females, younger participants, and among those with a history of CRC screening, all of which involved the SU vs. MT MRT comparisons. Only among younger participants (ages 50-59) was there a difference between SU vs. ST at 14 months. Given these results, we conclude from this trial the following: (1) the MRT intervention failed to show added benefit beyond the MT intervention, (2) the significant intervention effects involving the MT and MRT conditions can be explained by tailoring and/or the longitudinal nature of both interventions, and (3) the most compelling evidence in support of tailoring was found for the ST condition among younger participants, where a significant need for interventions exists at the national level. Directions for future research are discussed in light of the results summarized above.

In this paper the effect of uterine artery embolization (UAE) on sexual functioning and body image is investigated in a randomized comparison to hysterectomy for symptomatic uterine fibroids. The EMbolization versus hysterectoMY (EMMY) trial is a randomized controlled study, conducted at 28 Dutch hospitals. Patients were allocated hysterectomy (n = 89) or UAE (n 88). Two validated questionnaires (the Sexual Activity Questionnaire [SAQ] and the Body Image Scale [BIS]) were completed by all patients at baseline, 6 weeks, and 6, 12, 18, and 24 months after treatment. Repeated measurements on SAQ scores revealed no differences between the groups. There wasmore » a trend toward improved sexual function in both groups at 2 years, although this failed to reach statistical significance except for the dimensions discomfort and habit in the UAE arm. Overall quality of sexual life deteriorated in a minority of cases at all time points, with no significant differences between the groups (at 24 months: UAE, 29.3%, versus hysterectomy, 23.5%; p = 0.32). At 24 months the BIS score had improved in both groups compared to baseline, but the change was only significant in the UAE group (p = 0.009). In conclusion, at 24 months no differences in sexuality and body image were observed between the UAE and the hysterectomy group. On average, both after UAE and hysterectomy sexual functioning and body image scores improved, but significantly so only after UAE.« less

Early identification and treatment of actinic cheilitis (AC) is recommended. Although photodynamic therapy (PDT) is an attractive therapeutic option for AC, PDT for AC does not result in the same satisfactory outcomes as in actinic keratosis (AK). The aim of our study was to compare efficacy, recurrence rate, cosmetic outcome and safety between erbium:yttrium-aluminium-garnet ablative fractional laser-assisted methyl aminolaevulinate-PDT (Er:YAG AFL MAL-PDT) and standard MAL-PDT. Thirty-three patients with histologically confirmed AC randomly received either one session of Er:YAG AFL MAL-PDT or two sessions of MAL-PDT. In the MAL-PDT group, the second session of MAL-PDT was administered 7 days later. Patients were followed up at 1 week and 3 and 12 months, and biopsies were taken from all patients at 3 and 12 months after the last treatment session. At the final 12-month follow-up, cosmetic outcomes were assessed. Adverse events were assessed at week 1 of the treatment phase and every subsequent follow-up visit. In the per-protocol (PP) population, Er:YAG AFL MAL-PDT was significantly more effective (92% complete response rate) than MAL-PDT (59%; P = 0.040) at the 3-month follow-up, and differences in efficacy remained significant at the 12-month follow-up (85% in Er:YAG AFL MAL-PDT and 29% in MAL-PDT). The recurrence rate was significantly lower for Er:YAG AFL MAL-PDT (8%) than for MAL-PDT (50%) group at 12 months (P = 0.029). No significant difference in cosmetic outcome or safety was observed between Er:YAG AFL MAL-PDT and MAL-PDT. Ablative fractional laser pretreatment has significant benefit for the treatment of AC with PDT. © 2014 British Association of Dermatologists.

This randomized clinical trial investigated the influence of the utilization time of brush heads from different types of power toothbrushes [oscillating rotating (OR) and sonic action (SA)93; on oral hygiene (plaque accumulation and gingival inflammation) over a 6-month observation period. 49 participants were randomly allocated into two groups: use of the same brush head over 6 months (NR: non-replacement) or replacement of brush head every 4 weeks over 6 months (R: replacement). Each group was subdivided into two subgroups according to kind of toothbrush (TB) used (OR and SA). Modified Quigley-Hein plaque index (QHI), papilla bleeding index (PBI), and gingival index (GI) were recorded at baseline and 2, 8, 12, 16, and 24 weeks after baseline. After 24 weeks, participants of both groups (R and NR) received a new brush head. At week 26, final QHI, PBI, and GI were recorded. QHI decreased between baseline and follow-up visits in R groups (P< 0.05), with the exception of week 12 (P= 0.26). In NR groups, no significant decrease was detected (P> 0.05). There was no significant effect of time on PBI or GI in any of R subgroups (P> 0.05). In NR oscillating/rotating TB: significant increase in PBI and GI was detected 24 weeks after baseline (PBI: P= 0.02, GI: P= 0.03); sonic action TBs showed significant decrease in PBI at every follow-up visit (P< 0.05), except at 24 weeks after baseline (P= 0.73). GI was significantly decreased at 2 weeks after baseline only (P< 0.01). Six-month use of the same brush head reduced effectiveness in removing plaque, and gingival inflammation appeared to increase after a utilization time of over 4 months. Replacing brush heads is advised after 4 months.

Introduction Leishmaniasis is an important public health problem in the Americas. A Cochrane review published in 2009 analyzed 38 randomized controlled trials (RCT). We conducted a systematic review to evaluate the effects of therapeutic interventions for American cutaneous and mucocutaneous leishmaniasis. Methods All studies were extracted from PubMed, Embase, Lilacs (2009 to July, 2012 respectively), the Cochrane Central Register of Controlled Trials (6-2012) and references of identified publications. RCTs’ risk of bias was assessed. Results We identified 1865 references of interest; we finally included 10 new RCTs. The risk of bias scored low or unclear for most domains. Miltefosine was not significantly different from meglumine antimoniate in the complete cure rate at 6 months (4 RCT; 584 participants; ITT; RR: 1.12; 95%CI: 0.85 to 1.47; I2 78%). However a significant difference in the rate of complete cure favoring miltefosine at 6 months was found in L. panamensis and L. guyanensis (2 RCTs, 206 participants; ITT; RR: 1.22; 95%CI: 1.02 to 1.46; I2 0%). One RCT found that meglumine antimoniate was superior to pentamidine in the rate of complete cure for L. braziliensis (80 participants, ITT; RR: 2.21; 95%CI: 1.41 to 3.49), while another RCT assessing L. guyanensis did not find any significant difference. Although meta-analysis of three studies found a significant difference in the rate of complete cure at 3 months favoring imiquimod versus placebo (134 participants; ITT; RR: 1.45; 95%CI: 1.12 to 1.88; I2 0%), no significant differences were found at 6 and 12 months. Thermotherapy and nitric oxide were not superior to meglumine antimoniate. Conclusion Therapeutic interventions for American cutaneous and mucocutaneous leishmaniasis are varied and should be decided according to the context. Since mucosal disease is the more neglected form of leishmaniasis a multicentric trial should be urgently considered. PMID:23637917

The Montreal Cognitive Assessment (MoCA) is nowadays recommended for the screening of poststroke cognitive impairment. However, little is known about the temporal evolution of MoCA-assessed cognition after stroke. The objective of this study was to examine the temporal pattern of overall and domain-specific cognition at 2 and 6 months after stroke using the MoCA and to identify patient groups at risk for cognitive impairment at 6 months after stroke. Prospective cohort study in which 324 patients were administered the MoCA at 2 and 6 months post stroke. Cognitive impairment was defined as MoCA<26. Differences in cognitive impairment rates between 2 and 6 months post stroke were analyzed in different subgroups. Patients with MoCA score <26 at 2 months, who improved by ≥2 points by 6 months, were defined as reverters. Logistic regression analyses were used to identify determinants of (1) cognitive impairment at 6 months post stroke and (2) reverter status. Between 2 and 6 months post stroke, mean MoCA score improved from 23.7 (3.9) to 24.7 (3.5), P<0.001. Prevalence of cognitive impairment at 2 months was 66.4%, compared with 51.9% at 6 months (P<0.001). More comorbidity and presence of cognitive impairment at 2 months were significant independent predictors of cognitive impairment 6 months post stroke. No significant determinants of reverter status were identified. Although cognitive improvement is seen ≤6 months post stroke, long-term cognitive deficits are prevalent. Identifying patients at risk of cognitive impairment is, therefore, important as well as targeting interventions to this group. © 2016 American Heart Association, Inc.

To explore the effects of five different therapy in women at early stage of menopause on menopausal symptoms, quality of Life and cardiovascular risk factors. A total of 140 women at early stage of menopause were randomly divided into five groups. Thirty women took Conjugated estrogen and medroxyprogesterone acetate(CEE+ MPA) sequential therapy, 27 women took estradiol valerate and medroxyprogesterone acetate(E2V+ MPA) sequential therapy, 26 women took estradiol valerate and Progesterone Soft Capsules(E2V+ P) sequential therapy, 30 women took Kuntai capsule, and 27 took Cohosh extract.Patients in the Menopausal Hormone Therapy(MHT) groups took twelve cycles of treatment course, in the botanical drug and Chinese patent drug groups took twelve months. The KMI scalewas used to measure the level of menopausal symptoms. MENQOL scale was used to measure the health-related quality of life before and at the 3(rd) month, 6(th) month, 9(rd) month and 12(th) month after the treatment. Some serological indicators which related to cardiovascular risk factors were collected before and at the 12(th) month after the treatment. (1) KMI: It showed that the KMI in five groups after the treatment were significantly different(P<0.01), the group of CEE+ MPA decreased most(13±1). The KMI after the treatment were all significantly lower than that before. (2)MENQOL: It showed that the MENQOL in five groups were significantly different(P<0.01), the group of CEE+ MPA decreased most (84±3), then the group of Kuntai(85±3). The MENQOL after the treatment were all significantly lower than that before. (3)The change of cardiovascular risk factors: it showed that the serological indicators FBGin group of CEE+ MPA after the treatment were significantly lower than that before(P<0.05); the TC, LDL, FI in group of E2V+ MPA after the treatment were significantly lower than that before(P<0.05); the FBG, FI in group of E2V+ P after the treatment were significantly lower than that before(P<0.05). The MHT, botanical drug and Chinese patent drug have great clinical curative effects in treating perimenopause syndrome, improving the health-related quality of life and decreasing risk factors of cardiovascular disease.With rare adverse events and good clinical medication safety, they could be widely applied to clinic to women at early stage of menopause who was suffering menopausal symptoms.

Most maternal deaths in Mexico occur within health facilities, often attributable to suboptimal care and lack of access to emergency services. Improving obstetric and neonatal emergency care can improve health outcomes. We evaluated the impact of PRONTO, a simulation-based low-cost obstetric and neonatal emergency and team training program on patient outcomes. We conducted a pair-matched hospital-based trial in Mexico from 2010 to 2013 with 24 public hospitals. Obstetric and neonatal care providers participated in PRONTO trainings at intervention hospitals. Control hospitals received no intervention. Outcome measures included hospital-based neonatal mortality, maternal complications, and cesarean delivery. We fitted mixed-effects negative binomial regression models to estimate incidence rate ratios and 95% confidence intervals using a difference-in-differences approach, cumulatively, and at follow-up intervals measured at 4, 8, and 12 months. There was a significant estimated impact of PRONTO on the incidence of cesarean sections in intervention hospitals relative to controls adjusting for baseline differences during all 12 months cumulative of follow-up (21% decrease, P = 0.005) and in intervals measured at 4 (16% decrease, P = 0.02), 8 (20% decrease, P = 0.004), and 12 months' (20% decrease, P = 0.003) follow-up. We found no statistically significant impact of the intervention on the incidence of maternal complications. A significant impact of a 40% reduction in neonatal mortality adjusting for baseline differences was apparent at 8 months postintervention but not at 4 or 12 months. PRONTO reduced the incidence of cesarean delivery and may improve neonatal mortality, although the effect on the latter might not be sustainable. Further study is warranted to confirm whether obstetric and neonatal emergency simulation and team training can have lasting results on patient outcomes.

Intestinal dysbiosis has been described in Cystic Fibrosis (CF) and probiotics have been proposed to restore microbial composition. Aim of the study was to investigate the effects of Lactobacillus rhamnosus GG (LGG) on clinical outcomes in children with cystic fibrosis (CF). A multicentre, randomised double-blind, clinical trial was conducted in children with CF. After 6months of baseline assessment, enrolled children (2 to 16years of age) received Lactobacillus GG (6×10 9 CFU/day) or placebo for 12months. Primary outcomes were proportion of subjects with at least one pulmonary exacerbation and hospitalisation over 12months. Secondary endpoints were total number of exacerbations and hospitalisations, pulmonary function, and nutritional status. Ninety-five patients were enrolled (51/95 female; median age of 103±50months). In a multivariate GEE logistic analysis, the odds of experiencing at least one exacerbation was not significantly different between the two groups, also after adjusting for the presence of different microbial organisms and for the number of pulmonary exacerbations within 6months before randomisation (OR 0.83; 95% CI 0.38 to 1.82, p=0.643). Similarly, LGG supplementation did not significantly affect the odds of hospitalisations (OR 1.67; 95% CI 0.75 to 3.72, p=0.211). No significant difference was found for body mass index and FEV1. LGG supplementation had no effect on respiratory and nutritional outcomes in this large study population of children with CF under stringent randomised clinical trial conditions. Whether earlier interventions, larger doses, or different strains of probiotics may be effective is unknown. Copyright © 2017 European Cystic Fibrosis Society. Published by Elsevier B.V.

Introduction To compare the results of cold-knife optical internal urethrotomy (OIU) and Holmium:YAG laser internal urethrotomy (HIU) in primary bulbar urethral strictures. Material and methods A total of 63 patients diagnosed with primary bulbar urethral stricture between August 2014 and September 2015 were assigned to the OIU (n = 29) and HIU (n = 34) groups. The demographic variables, biochemistry panels, and preoperative and postoperative uroflowmetry results including the maximum flow rate (Qmax) and mean flow rate (Qmean) values, retrograde urethrography, and diagnostic flexible urethroscopy findings were recorded prospectively. Demographic features and preoperative values were not statistically different between groups (p >0.05). Mean surgical times were 18.4 ±2.3 min for OIU and 21.9 ±3.8 min for HIU groups, which was statistically significant (p <0.05). There was no significant difference in complication rates in both groups (p = 0.618). Results Postoperative Qmax values were increased in both groups even though postoperative Qmax values were not significantly different between the two groups in the short- and long-term results at 3, 6, and 12 months (p >0.05). There was no recurrence in the first 3 months in either group. The urethral stricture recurrence rate up to month 12 was not statistically significant for the OIU group (n = 6, 20.7%) as compared to the HIU group (n = 11, 32.4%; p = 0.299). At follow-up, the SFR and IFR was 96% and 88% at 3-months, and 82% and 71% at 12-months, respectively (p <0.001). While almost three-quarters of patients were stone and infection free at 12-months, the majority of those with stones recurrence also had recurrence of their UTI. Conclusions HIU is an alternative method to OIU, and it has similar success rates in the treatment of short segment bulbar urethral strictures. PMID:29732217

To evaluate the possible role of tamoxifen (selective estrogen receptor modulators, SERM) in treating bleeding irregularities associated with Norplant contraceptive use. Randomized clinical trial including 100 Norplant users complaining of vaginal bleeding irregularities. The trial was conducted in the Family Planning Clinic of Assiut University Hospital. Women were assigned at random to receive tamoxifen tablets (10 mg) twice daily for 10 days or similar placebo. Women were followed-up for 3 months. The end points were percentage of women who stopped bleeding during treatment, bleeding/spotting days during the period of follow-up, effect of treatment on their lifestyle, and side effects and discontinuation of contraception. There was good compliance with treatment. At the end of treatment, a significantly higher percentage of tamoxifen users stopped bleeding in comparison to the control group (88% vs. 68%, respectively; p=.016). Women who used tamoxifen had significantly less bleeding and/or spotting days than women who used placebo, during the first and second months. During the third month, there were no significant differences between the two groups. Women who used tamoxifen reported improvement in performing household activities, religious duties and in sexual life, during the first 2 months. In the third month, there were no differences between the two groups. There were no significant differences between tamoxifen and placebo groups in reporting side effects. In the group who used tamoxifen, two women discontinued Norplant use because of bleeding vs. nine women in the placebo group. Tamoxifen use at a dose of 10 mg twice daily orally, for 10 days, has a beneficial effect on vaginal bleeding associated with Norplant use. In addition, the bleeding pattern was better in women who used tamoxifen for the following 2 months after treatment. However, these results have to be confirmed in a larger trial before advocating this line of treatment.

The resistance of a pacing lead negatively correlates to current consumption. A prospective, randomized trial was conducted to evaluate the effect of a high impedance ventricular lead (CapSure Z) on generator longevity compared to a conventional lead (CapSure SP) eighty-nine patients were included in the study (51 male, 37 female, age 70.0+/-10.3 years). Forty-six patients received a CapSure SP lead (5024 bipolar), and 43 patients received a CapSure Z lead (5034 bipolar) in a randomized fashion. Follow-up data collected at 5 days, 3, 6, and 12 months postimplant included: lead impedance, pacing and sensing thresholds, impulse energy, and estimated time to replacement. All parameters were collected via pacemaker telemetry; the time to replacement was calculated automatically by a programmed algorithm of the pacemaker. There was no difference in the performance of the atrial lead when a dual chamber device was indicated. The CapSure Z leads displayed statistically significant higher impedance values than the CapSure SP lead in all follow-up periods. There was no significant difference in lead related complications. No significant differences were observed between pacing and sensing thresholds in both groups. The CapSure Z leads provided a significant reduction in current drain, resulting in a reduction of mean energy consumption at the 12-month follow-up from 10.4+/-5.0 microJ in the CapSure SP group to 6.6+/-1.4 microJ in the CapSure Z group (median from 9.9 microJ to 6.9 microJ, respectively), providing an estimated increase in mean longevity of more than 1 year from 81.1+/-23.5 months in the CapSure SP group to 94.5+/-13.4 months in the CapSure Z group (median: 76.5 months to 95.0 months, respectively). The use of a high resistance lead for ventricular pacing appears to result in a clinically relevant extension of generator longevity.

Serum eye drops are used for the treatment of ocular surface disease (eg, Sicca syndrome). The objective of this experimental study was to investigate whether they maintain their wound-healing potency after a prolonged storage of 6 months at -20 °C and to find a parameter that can serve as a quality and stability indicator. After obtaining whole blood from 10 volunteers and preparing 100% (AS100), 50% (AS50), and 20% (AS20) serum eye drops, epitheliotrophic factors including EGF, fibronectin, vitamins A and E, albumin, and immunoglobulin A were quantified before and after storage for 7 days at 6 °C or 3 and 6 months at -20 °C. Human corneal epithelial (HCE) cell lines were used to investigate proliferation, migration, and overall wound healing potency of the cells in response to different serum preparations. The proliferation, migration, and wound healing of HCE cells were measured after incubation with different serum eye drop concentrations and after different storage conditions. The concentration of epidermal growth factor, fibronectin, vitamins A and E, immunoglobulin A, and albumin showed no significant reduction over the test period. Proliferation, migration, and wound healing of HCE cells was significantly better after incubation with undiluted serum in comparison with diluted serum. No significant loss of cytokine concentration, wound healing, and proliferation effect in HCE culture of AS100, AS50, and AS20 could be detected over the 6 months of storage. The concentration of a spectrum of cytokines involved in corneal epithelial wound healing and the epitheliothrophic effect of serum are not significantly changed after a prolonged storage of 6 months at -20 °C. Hence, it seems justifiable to provide patients with appropriate freezer capacity with a 6-month supply of autologous serum eye drops. Albumin--which is known to be relevant for ocular surface health--could serve as a cost-effective parameter for stability controls.

The aim of this study was to evaluate the effect of an Assertive Community Treatment (ACT) program on psychiatric symptoms, global functioning, life satisfaction, and recovery-promoting relationships among individuals with mental illness. Participants were patients at the Suwon Mental Health Center. Thirty-two patients were part of the ACT program and 32 patients matched for age, sex, and mental illness were in a standard case-management program and served as a control group. Follow-up with patients occurred every 3 months during the 15 months after a baseline interview. Participants completed the Brief Psychiatric Rating Scale (BPRS), Global Assessment of Functioning (GAF) Scale, Life Satisfaction Scale, and Recovery-Promoting Relationship Scale (RPRS). No significant differences were noted in the sociodemographic characteristics of the ACT and the case-management group. According to the BPRS, the ACT group showed a significant reduction in symptom severity, but the ACT program was not significantly more effective at reducing psychiatric symptoms from baseline to the 15-month follow-up compared to the case-management approach. The ACT group showed more significant improvement than the control group in terms of the GAF Scale. Both groups showed no significant differences in the change of life satisfaction and in the change of recovery-promoting relationships. We observed a significant increase in recovery-promoting relationships in the control group, but the degree of change of recovery-promoting relationships through time flow between groups was not significantly different. In this study, we observed that ACT was significantly better at improving the GAF than case management and that participation in ACT was associated with a significant decrease in BPRS scores. However, ACT did not demonstrate an absolute superiority over the standard case-management approach in terms of the BPRS and the measures of life satisfaction and recovery-promoting relationships. ACT may have some advantages over a standard case management approach.

Cognitive remediation performed in a cognitive laboratory was compared with a sham control using portable brain games to study effects on vocational, neurocognitive, and functional outcomes for participants with psychotic disorders in vocational rehabilitation (VR). Seventy-seven participants (61% schizophrenia, 39% other psychosis) in transitional (45.5%) or supported employment (54.5%) were randomly assigned to 6 months of portable cognitive-games (CG) or cognitive remediation (CR) plus a weekly goal-setting group, and evaluated during training, post-training and at 12 months. Overall rates of employment did not differ significantly at 12-month follow-up; however, VR + CG attained employment more rapidly during training. A significant time by condition interaction favored VR + CR on Quality of Life Total Score and Instrumental Functioning over 12 months. Neurocognitive outcomes favored VR + CR, particularly on attention. Training hours related significantly to neurocognitive improvement regardless of condition. No differences were found in training adherence despite portability for VR + CG. Results indicate that VR + CR had significantly greater effect than VR + CG on neurocognition and community functioning, but not on employment outcome. Job attainment rates during the training period revealed a potential advantage for portable training raising new questions concerning how cognitive remediation can be most effectively integrated with VR.

Several patient groups request treatment in a warm climate, in spite of the fact that the effects of such treatment are undocumented. 47 children and 40 adults with neuromuscular diseases were recruited, stratified according to sex, use or non-use of electric wheelchair, primary myopathy or hereditary neuropathy, and randomised into two adult and two children groups. The patients were treated in a rehabilitation centre, either on Lanzarote or in Norway. All patients were monitored with physical tests and questionnaires at the start of the study, at the end of the treatment period, after three months (all groups) and after six months (adults only). No significant differences in effect between the groups were found. In the warm climate, the adult patient group showed a statistically significant improvement regarding pain, quality of life, depression, and results of physical tests at the end of treatment. After three months, the improvement in physical tests was still present. Among adult patients treated in Norway, improvement in physical tests was statistically significant after three months, but not at the end of the treatment period. This study did not show a statistically significant difference between patients with various neuromuscular diseases treated in a warm climate compared to similar patients treated in Norway.

Introduction. Dyslipidemia like other chronic degenerative diseases is pandemic in Latin America and around the world. A lot of patients asking for body contouring surgery can be sick without knowing it. Objective. Observe the lipid profile of patients with dyslipidemia, before and three months after an abdominoplasty. Methods. Patients candidate to an abdominoplasty without morbid obesity were followed before and three months after the surgery. We compared the lipid profile, glucose, insulin, and HOMA (cardiovascular risk marker) before and three months after the surgery. We used Student's t test to compare the results. A P value less than 0.05 was considered as significant. Results. Twenty-six patients were observed before and after the surgery. At the third month, we found only statistical differences in LDL and triglyceride values (P 0.04 and P 0.03). The rest of metabolic values did not reach statistical significance. Conclusion. In this group of patients with dyslipidemia, at the third month, only LDL and triglyceride values reached statistical significances. There is no significant change in glucose, insulin, HOMA, cholesterol, VLDL, or HDL. PMID:23956856

This study examined the relationships of stress and social support to maternal attitudes and early mother-infant interactive behavior. 52 mother-premature infant pairs and 53 mother-full-term infant pairs were seen for structured home interviews at 1 month, and behavioral interactions at 4 months. Maternal life stress, social support, life satisfaction, and satisfaction with parenting were assessed at the 1-month home visit. Although no group differences were found, both stress and support significantly predicted maternal attitudes at 1 month and interactive behavior at 4 months when data were pooled. Mothers with greater stress were less positive in their attitudes and behavior, while mothers with greater support were significantly more positive. Intimate support proved to have the most general positive effects. Additionally, social support moderated the adverse effects of stress on mother's life satisfaction and on several behavioral variables. Maternal social support was further found to have several significant effects on infant interactive behavior. Results are discussed in terms of the ecological significance of social support to parenting and infants' early development.

To compare the clinical efficacies and adverse reactions between transcatheter arterial chemoembolization (TACE), γ-ray 3-dimensional fractionated stereotactic conformal radiotherapy (FSCR), and TACE combined with FSCR for primary hepatocellular carcinoma.The study was approved by the Institutional Review Board, and informed consent was waived due to the retrospective study design. About 121 patients met the inclusion criteria and were included in this study, from March 2008 to January 2010, in the Second Xiangya Hospital. Forty-six patients underwent TACE alone, 36 patients underwent γ-knife alone, and 39 were treated by γ-knife combined with TACE. Short-term effects, overall survival rates, adverse reactions, and survival times were compared between the 3 treatment groups.Short-term effects were observed in 41.3% of the TACE group, 33.3% of the γ-knife group, and 64.1% of the TACE combined γ-knife group (P = .020). Overall survival rates at 6,12, 18, and 24 months were 50%, 34.8%, 28.3%, and 21.7% for the TACE group, 36.1%, 30.6%, 16.7%, and 11.1% for γ-knife group, and 84.6%, 71.8%, 61.5%, and 30.8% for TACE combined γ-knife group, respectively. The differences in the overall survival rates at 6, 12, and 18 months between the 3 groups were statistically significant (P = 0), but the overall survival rates at 24 months in the 3 groups were not significantly different (P = .117). The median survival time was 7 months for the TACE group, 3 months for the γ-knife group, and 20 months for the TACE combined γ-knife group (P = 0). There were statistically significant differences (P = .010) of leukopenia between the 3 groups, and no statistically significant differences of (P > .05) thrombocytopenia, anemia, nausea, vomiting, and liver function lesions.TACE combined with γ-knife for primary hepatocellular carcinoma is superior to TACE or γ-knife alone in short-term and long-term effects. This procedure is a mild, safe, and effective treatment for primary hepatocellular carcinoma.

To determine whether a Web-based interactive breastfeeding monitoring system increased breastfeeding duration, exclusivity, and intensity as primary outcomes and decreased symptoms of postpartum depression as a secondary outcome. Two-arm, randomized controlled trial. Three hospitals in the Midwestern United States. One hundred forty one (141) mother-newborn dyads were recruited before discharge. Postpartum women were randomly assigned to the control or intervention groups. Women in the control group (n = 57) followed the standard hospital protocol, whereas women in the intervention group (n = 49) were given access to an online interactive breastfeeding monitoring system and were prompted to record breastfeeding and infant output data for 30 days. A follow-up online survey was sent to both groups at 1, 2, and 3 months to assess breastfeeding outcomes and postpartum depression. For mothers and infants, there were no significant differences in demographics between groups. No significant differences in breastfeeding outcomes were found between groups at discharge (p = .707). A significant difference in breastfeeding outcomes was found between groups at 1, 2, and 3 months (p = .027, p < .001, and p = .002, respectively). Members of the intervention group had greater exclusive breastfeeding rates at 1, 2, and 3 months. By the end of the third month, 84% of the intervention group was breastfeeding compared with 66% of the control group. Postpartum depression symptom scores decreased for both groups at 1, 2, and 3 months (control group: 4.9 ± 3.9, 4.3 ± 4.9, and 3.2 ± 3.9, respectively; intervention group: 4.7 ± 4.5, 3.0 ± 3.4, and 2.8 ± 3.6, respectively). However, there was no significant difference between groups at 1, 2, and 3 months (p = .389, .170, and .920, respectively) for depression. The Web-based interactive breastfeeding monitoring system may be a promising intervention to improve breastfeeding duration, exclusivity, and intensity.

Despite the popularity of the low-carbohydrate, high-protein, high-fat (Atkins) diet, no randomized, controlled trials have evaluated its efficacy. We conducted a one-year, multicenter, controlled trial involving 63 obese men and women who were randomly assigned to either a low-carbohydrate, high-protein, high-fat diet or a low-calorie, high-carbohydrate, low-fat (conventional) diet. Professional contact was minimal to replicate the approach used by most dieters. Subjects on the low-carbohydrate diet had lost more weight than subjects on the conventional diet at 3 months (mean [+/-SD], -6.8+/-5.0 vs. -2.7+/-3.7 percent of body weight; P=0.001) and 6 months (-7.0+/-6.5 vs. -3.2+/-5.6 percent of body weight, P=0.02), but the difference at 12 months was not significant (-4.4+/-6.7 vs. -2.5+/-6.3 percent of body weight, P=0.26). After three months, no significant differences were found between the groups in total or low-density lipoprotein cholesterol concentrations. The increase in high-density lipoprotein cholesterol concentrations and the decrease in triglyceride concentrations were greater among subjects on the low-carbohydrate diet than among those on the conventional diet throughout most of the study. Both diets significantly decreased diastolic blood pressure and the insulin response to an oral glucose load. The low-carbohydrate diet produced a greater weight loss (absolute difference, approximately 4 percent) than did the conventional diet for the first six months, but the differences were not significant at one year. The low-carbohydrate diet was associated with a greater improvement in some risk factors for coronary heart disease. Adherence was poor and attrition was high in both groups. Longer and larger studies are required to determine the long-term safety and efficacy of low-carbohydrate, high-protein, high-fat diets. Copyright 2003 Massachusetts Medical Society

To evaluate the impact on ovarian reserve between two different methods ofhemostasis after laparoscopic ovarian endometrioma excision. A randomized controlled study was conducted from January to December 2013 in Thammasat University Hospital, Thailand. Reproductive women, age 18-45years who underwent laparoscopic ovarian cystectomy were randomized in electrocoagulation and suture groups. Clinical baseline data and ovarian reserve outcome (anti-Mullerian hormone (AMH)) were evaluated. Fifty participants were recruited and randomized in two groups. Electrocoagulation and suture groups consisted of 25 participants. Baseline characteristics between 2 groups (age, weight, BMI, height, cyst diameter, duration and estimated blood loss) were not statistically different. There were no significant difference of AMIH between electrocoagulation and suture group atpre-operative (2.90±2.26 vs. 2.52±2.37 ng/ml), 1 week (1.78±1.51 vs. 1.99±1.71 ng/ml), 1 month (1.76±1.50 vs. 2.09±1.62 ng/ml), 3 months (2.09±1.66 vs. 1.96±1.68 ng/ml) and 6 months (2.11±1.84 vs 1.72±1.68 ng/ml), respectively. However mean AMH ofboth groups significantly decreased since the first week of operation. Effect oflaparoscopic ovarian surgery had significantly declined and sustained AMH level until 6 months. Laparoscopic cystectomy of ovarian endometrioma has negative impact to ovarian reserve. Either electroco- agulation or suture method had no different effects.

In the present study, we examined the influence of a home-based, DVD-delivered exercise intervention on daily sedentary time and breaks in sedentary time in older adults. Between 2010 and 2012, older adults (i.e., aged 65 or older) residing in Illinois (N = 307) were randomized into a 6-month home-based, DVD-delivered exercise program (i.e., FlexToBa; FTB) or a waitlist control. Participants completed measurements prior to the first week (baseline), following the intervention period (month 6), and after a 6 month no-contact follow-up (month 12). Sedentary behavior was measured objectively using accelerometers for 7 consecutive days at each time point. Differences in daily sedentary time and breaks between groups and across the three time points were examined using mixed-factor analysis of variance (mixed ANOVA) and analysis of covariance (ANCOVA). Mixed ANOVA models revealed that daily minutes of sedentary time did not differ by group or time. The FTB condition, however, demonstrated a greater number of daily breaks in sedentary time relative to the control condition (p = .02). ANCOVA models revealed a non-significant effect favoring FTB at month 6, and a significant difference between groups at month 12 (p = .02). While overall sedentary time did not differ between groups, the DVD-delivered exercise intervention was effective for maintaining a greater number of breaks when compared with the control condition. Given the accumulating evidence emphasizing the importance of breaking up sedentary time, these findings have important implications for the design of future health behavior interventions.

Compared to literature on seasonal variation in mood and well-being, reports on seasonality of trouble sleeping are scarce and contradictive. To extend geography of such reports on example of people naturally exposed to high-amplitude annual variation in daylength and/or temperature. Participants were the residents of Turkmenia, West Siberia, South and North Yakutia, Chukotka, and Alaska. Health and sleep-wake adaptabilities, month-to-month variation in sleeping problems, well-being and behaviors were self-assessed. More than a half of 2398 respondents acknowledged seasonality of sleeping problems. Four of the assessed sleeping problems demonstrated three different patterns of seasonal variation. Rate of the problems significantly increased in winter months with long nights and cold days (daytime sleepiness and difficulties falling and staying asleep) as well as in summer months with either long days (premature awakening and difficulties falling and staying asleep) or hot nights and days (all 4 sleeping problems). Individual differences between respondents in pattern and level of seasonality of sleeping problems were significantly associated with differences in several other domains of individual variation, such as gender, age, ethnicity, physical health, morning-evening preference, sleep quality, and adaptability of the sleep-wake cycle. These results have practical relevance to understanding of the roles playing by natural environmental factors in seasonality of sleeping problems as well as to research on prevalence of sleep disorders and methods of their prevention and treatment in regions with large seasonal differences in temperature and daylength.

To date, there are no data regarding the effect of the transdermal combined estrogen and progestin contraceptive Ortho Evra on bone mineral content (BMC) and bone mineral density (BMD). We examined the effects of transdermally delivered ethinyl estradiol and norelgestromin on whole body (WB) BMC and BMD of the hip and lumbar spine (LS) of adolescent girls. In a matched case-control study, girls (n = 5) who applied Ortho Evra for days 1-21 followed by days 22-28 free of medication for 13 cycles (about 12 months) were compared with 5 age- and ethnicity-matched control girls. Evaluations of calcium intake; bone-protective physical activity; bone densitometry (DXA, QDR 4500A, Hologic); bone formation markers serum osteocalcin (OC) and bone-specific alkaline phosphatase (BAP); bone resorption marker urinary N-telopeptide (uNTX); insulin growth factor-1 (IGF-1); and sex hormone binding globulin (SHBG) were carried out at initiation, 6 months, and 12 months. Changes from baseline were compared using mixed models, adjusting for follow-up comparisons using the Holm Test (sequential Bonferroni). There were no significant differences (SD) between groups at baseline in age, gynecologic age, WBBMC, hip BMD, and LSBMD. Girls on Ortho Evra did not change significantly in WBBMC (12-month mean increase 0.2% +/- 0.8%), whereas controls did (3.9% +/- 1.8%, P < or = .001, adjusted P = .002), with SD between the 2 groups (P = .007, adjusted P = .036). Adolescents on Ortho Evra did not change significantly in hip BMD (12-month mean increase 0.5% +/- 0.6%), whereas controls did (2.7% +/- 0.6%, P < or = .001, adjusted P = .004), with SD between the 2 groups (P = .024) prior to adjustment for multiple comparisons, but no SD after adjustment (P = .096). Similarly, although the increase in LSBMD within the control group after 12 months (mean increase 2.8% +/- 1.0%) was statistically significant (P = .009, adjusted P = .044), the change within the treatment group (12-month mean increase 0.8% +/- 0.8%) was not. However, percent LSBMD changes after 12 months did not significantly differ between the 2 groups before or after adjustment for multiple comparisons. Calcium intake and bone-protective physical activity did not significantly predict BMC and BMD changes of study participants. There was a significantly greater increase in SHBG levels in the treatment group after 6 months (P = .003, adjusted P = .013) and 12 months (P < or = .001, adjusted P < or = .001) than in controls. Changes in levels of OC, BAP, uNTX, and IGF-1 were not significantly different between the 2 groups. Ortho Evra use attenuates bone mass acquisition in young women who are still undergoing skeletal maturation. This attenuation may be attributed in part to increased SHBG levels, which reduce the concentrations of free estradiol and free testosterone that are available to interact with receptors on the bone. Clinical implications remain to be determined in studies with a larger number of adolescents. Copyright 2010 North American Society for Pediatric and Adolescent Gynecology. Published by Elsevier Inc.

Physical activity (PA) improves fatigue and quality of life (QOL) in cancer survivors. Our aim was to assess whether a 2-month PA intervention improves fatigue and QOL for people with advanced lung cancer. Participants with advanced lung cancer, Eastern Cooperative Oncology Group performance status (PS) ≤2, >6 months life expectancy, and ability to complete six-min walk test, were stratified (disease stage, PS 0-1 versus 2, centre) and randomized (1:1) in an open-label study to usual care (UC) (nutrition and PA education materials) or experimental intervention (EX): UC plus 2-month supervised weekly PA and behaviour change sessions. Assessments occurred at baseline, 2, 4, and 6 months. The primary endpoint was fatigue [Functional Assessment of Cancer Therapy-Fatigue (FACT-F) questionnaire] at 2 months. The study was designed to detect a difference in mean FACT-F subscale score of 6. Analysis was intention-to-treat using linear mixed models. We recruited 112 patients: 56 (50.4%) were randomized to EX, 55(49.5%) to UC; 1 ineligible. Male 55%; median age 64 years (34-80); 106 (96%) non-small cell lung cancer; 106 (95.5%) stage IV. At 2, 4 and 6 months, 90, 73 and 62 participants were assessed, respectively, with no difference in attrition between groups. There were no significant differences in fatigue between the groups at 2, 4 or 6 months: mean scores at 2 months EX 37.5, UC 36.4 (difference 1.2, 95% CI - 3.5, 5.8, P = 0.62). There were no significant differences in QOL, symptoms, physical or functional status, or survival. Adherence to the intervention was good but the intervention group did not increase their PA enough compared to the control group, and no difference was seen in fatigue or QOL.

2014-10-01

To compare long-term outcomes and retreatment rates for patients with Dupuytren disease who underwent needle aponeurotomy (NA) combined with a series of triamcinolone acetonide injections or underwent NA alone as part of a prior randomized controlled trial. During this follow-up study, 44 of 47 participants in the original study were examined as needed between 6 and 53 months from their initial procedure. Those who had not been reassessed within 18 months of the original NA were asked to return for follow-up. The average total active extension deficit (TAED) of previously treated joints was compared between groups 7 to 12, 13 to 24, 25 to 36, and 37 to 48 months following treatment. Timing of retreatment (if performed) was recorded. Forty-four participants returned for assessment an average of 4.8 times over 53 months. Mean TAED was significantly less in needle aponeurotomy triamcinolone injection patients at 6 months and between 13 and 24 months. Sixty-two percent of NA group patients and 30% of needle aponeurotomy triamcinolone injection patients returned for a second treatment on the same digit(s) (retreatment). This difference was not significant. Mean time to retreatment and mean TAED immediately prior to retreatment did not differ significantly between groups. Kaplan-Meier survival estimates demonstrated a significantly higher percentage of NA group patients expected to return for retreatment by 24 but not by 36 months. Younger age, more than one joint treated at the initial NA, and TAED severity throughout the follow-up period were associated with earlier retreatment. Serial triamcinolone injections combined with NA was associated with lower TAED for up to 24 months. A larger study would more accurately quantify the potential benefits of combining triamcinolone injections with NA for treatment of Dupuytren disease. Therapeutic III.

Can We Improve the Tolerance of an Ocular Prosthesis by Enhancing Its Surface Finish?

PubMed

Litwin, Andre S; Worrell, Emma; Roos, Jonathan C P; Edwards, Barry; Malhotra, Raman

Patients who wear an ocular prosthesis frequently suffer with dry eye symptoms and socket discharge, often on a daily basis. The aim of the study was to determine whether a smoother, optical quality polish of the prosthesis' surface could improve symptoms and wear tolerance. The study was designed as single-center, single-masked, prospective randomized controlled trial. Eighty-eight consecutive patients undergoing annual ocular prosthesis maintenance review were approached from the prosthesis clinic. Forty-one out of 49 eligible patients were recruited. Participants were randomized to either a standard or a higher "optical quality" polish of their prosthesis. At entry to the trial, at 1 month, and 12 months they completed a questionnaire covering cleaning, lubricant use, inflammation, discomfort, and discharge. Lower scores indicated better tolerance of the prosthesis. At each visit, the prosthesis was stained and photographed against a standard background to assess deposit build up. Primary outcome measures were 1) a subjective questionnaire score and 2) an objective assessment of surface deposit build-up on prosthetic eyes by standardized photographic grading. Forty-one patients participated in the study. The median age of their prosthesis was 36 months (range 9 months-40 years). There was no statistically significant difference in questionnaire scores or deposit build up between the 2 groups at baseline. By 12-months, the higher optical quality polish showed a statistically significant reduction in symptoms and frequency of discharge (2.19 vs. 3.85; p = 0.05-lower scores better). Scoring of the prosthesis' deposit build-up showed a significant difference at 1 month, but this was not sustained at 12 months. Creating an optical quality finish to an ocular prosthesis reduces deposit build up on artificial eyes. The authors found this modification improved patient tolerance at 12 months.

Insoles are commonly used to assist in the prevention of diabetic neuropathic foot ulceration. Insole replacement is often triggered only when foot lesions deteriorate, an indicator that functional performance is comprised and patients are exposed to unnecessary ulcer risk. We investigated the durability of insoles used for ulcer prevention in neuropathic diabetic feet over 12 months. Sixty neuropathic individuals with diabetes were provided with insoles and footwear. Insole durability over 12 months was evaluated using an in-shoe pressure measurement device and through repeated measurement of material depth at the first metatarsal head and the heel seat. Analysis of variance was performed to assess change across time (at issue, 6 months, and 12 months). Analyses were conducted using all available data (n = 43) and compliant data (n = 18). No significant difference was found in the reduction of mean peak pressure tested across time (P < .05). For both sites, significant differences in insole depth were identified between issue and 6 months and between issue and 12 months but not between 6 and 12 months (P < .05). Most insole compression occurred during the initial 6 months. Visual material compression does not seem to be a reliable indicator of insole usefulness. Frequency of insole replacement is best informed by a functional review of effect determined using an in-shoe pressure measurement system. These results suggest that insoles for diabetic neuropathic patients can be effective in maintaining peak pressure reduction for 12 months regardless of wear frequency.

The aim of the study was to assess the 6-months treatment efficacy and 24-month follow up of three different therapeutic programs (A. moclobemide and supportive guidance, B. group cognitive-behavioral therapy and pill placebo, and C. combination of moclobemide and group cognitive-behavioral therapy) in patients with a generalized form of social phobia. Eighty one patients (38 males and 43 females) were randomly assigned to three different therapeutic programs. Patients were regularly assessed on a monthly basis by an independent rater on the LSAS (Liebowitz Social Anxiety scale), CGI (Clinical Global Impression) for severity and change and BAI (Beck Anxiety Inventory). Altogether, sixty-six patients completed the six month treatment period and 15 patients dropped out. All therapeutic groups showed significant improvement. A combination of CBT and pharmacotherapy yielded the most rapid effect. Moclobemide was superior for the reduction of the subjective general anxiety (BAI) during the first 3 months of treatment, but its influence on avoidant behavior (LSAS avoidance subscale) was less pronounced. Conversely, CBT was the best choice for reduction of avoidant behavior while a reduction of subjective general anxiety appeared later than in moclobemide. After 6 months of treatment there were best results reached in groups treated with CBT and there was no advantage of the combined treatment. The relapse rate during the 24-month follow up was significantly lower in the group treated with CBT in comparison with the group A. formerly treated with moclobemide alone.

During ligament balancing for severe medial contracture in varus knee total knee arthroplasty (TKA), complete distal release of the medial collateral ligament (MCL) or a medial epicondylar osteotomy can be necessary if a large amount of correction is needed. This study retrospectively reviewed 9 cases of complete distal release of the MCL and 11 cases of medial epicondylar osteotomy which were used to correct severe medial contracture. The mean follow-up periods were 46.5 months (range, 36 to 78 months) and 39.8 months (range, 32 to 65 months), respectively. There were no significant differences in the clinical results between the two groups. However, the valgus stress radiograph revealed significant differences in medial instability. In complete distal release of the MCL, some stability was obtained by repair and bracing but the medial instability could not be removed completely. Medial epicondylar osteotomy for a varus deformity in TKA could provide constant medial stability and be a useful ligament balancing technique.

To evaluate the efficacy of orlistat to enhance weight loss in obese adolescents. The study was a 6-month randomized, double-blind, placebo-controlled trial to compare the effects of orlistat (120 mg orally 3 times a day) and placebo on reduction of body mass index (BMI). Forty adolescents between 14 and 18 years of age with a mean BMI of 40 kg/m2 entered the protocol between December 2002 and February 2003. Study subjects stayed overnight in the General Clinical Research Center, during which dietary records were reviewed and lifestyle recommendations were given. The study participants received either orlistat (120 mg orally 3 times a day) or placebo and were assessed monthly for 6 months. At 0, 3, and 6 months, fasting laboratory tests were performed. The primary end point was the change in BMI from baseline to 6 months. Secondary outcomes included changes in weight, lean body mass, and results of blood chemistry studies. No statistically significant difference was noted between the 2 study groups for decrease in BMI from baseline to 6 months (P = 0.39). The decrease in BMI within the orlistat group (-1.3 +/- 1.6 kg/m2; P = 0.04) and within the placebo group (-0.8 +/- 3.0 kg/m2; P = 0.02), however, was statistically significant. Laboratory measurements did not differ between the 2 groups. In comparison with the placebo group, the orlistat group had increased adverse events, primarily gastrointestinal symptoms and findings. In this study of obese adolescents, orlistat did not significantly reduce BMI in comparison with placebo at 6 months.

Stochastic characteristics of the Benue River streamflow process are examined under conditions of data austerity. The streamflow process is investigated for trend, non-stationarity and seasonality for a time period of 26 years. Results of trend analyses with Mann-Kendall test show that there is no trend in the annual mean discharges. Monthly flow series examined with seasonal Kendall test indicate the presence of positive change in the trend for some months, especially the months of August, January, and February. For the stationarity test, daily and monthly flow series appear to be stationary whereas at 1%, 5%, and 10% significant levels, the stationarity alternative hypothesis is rejected for the annual flow series. Though monthly flow appears to be stationary going by this test, because of high seasonality, it could be said to exhibit periodic stationarity based on the seasonality analysis. The following conclusions are drawn: (1) There is seasonality in both the mean and variance with unimodal distribution. (2) Days with high mean also have high variance. (3) Skewness coefficients for the months within the dry season period are greater than those of the wet season period, and seasonal autocorrelations for streamflow during dry season are generally larger than those of the wet season. Precisely, they are significantly different for most of the months. (4) The autocorrelation functions estimated “over time” are greater in the absolute value for data that have not been deseasonalised but were initially normalised by logarithmic transformation only, while autocorrelation functions for i = 1, 2, ..., 365 estimated “over realisations” have their coefficients significantly different from other coefficients.

Despite recent advances in the understanding of clinical aspects of sex differences in Alzheimer's disease (AD), the underlying mechanisms, for instance, how sex modifies AD risk and why the female brain is more susceptible to AD, are not clear. The purpose of this study is to elucidate sex disparities in brain aging profiles focusing on 2 major areas-energy and amyloid metabolism-that are most significantly affected in preclinical development of AD. Total RNA isolated from hippocampal tissues of both female and male 129/C57BL/6 mice at ages of 6, 9, 12, or 15 months were comparatively analyzed by custom-designed Taqman low-density arrays for quantitative real-time polymerase chain reaction detection of a total of 182 genes involved in a broad spectrum of biological processes modulating energy production and amyloid homeostasis. Gene expression profiles revealed substantial differences in the trajectory of aging changes between female and male brains. In female brains, 44.2% of genes were significantly changed from 6 months to 9 months and two-thirds showed downregulation. In contrast, in male brains, only 5.4% of genes were significantly altered at this age transition. Subsequent changes in female brains were at a much smaller magnitude, including 10.9% from 9 months to 12 months and 6.1% from 12 months to 15 months. In male brains, most changes occurred from 12 months to 15 months and the majority were upregulated. Furthermore, gene network analysis revealed that clusterin appeared to serve as a link between the overall decreased bioenergetic metabolism and increased amyloid dyshomeostasis associated with the earliest transition in female brains. Together, results from this study indicate that: (1) female and male brains follow profoundly dissimilar trajectories as they age; (2) female brains undergo age-related changes much earlier than male brains; (3) early changes in female brains signal the onset of a hypometabolic phenotype at risk for AD. These findings provide a mechanistic rationale for female susceptibility to AD and suggest a potential window of opportunity for AD prevention and risk reduction in women.

High altitude-induced alterations in pituitary, gonadal and adrenal hormones were studied in (i) eugonadal men from the armed forces who were resident at sea level (SL), (ii) SL residents staying at an altitude of 3542 m for periods ranging from 3 to 12 months (acclimatized lowlanders, ALL), (iii) ALL who stayed at 6300 m for 6 months, (iv) ALL who trekked from 3542 to 5080 m and stayed at an altitude of more than 6300 m in the glacier region for 6 months, and (v) high-altitude natives (HAN) resident at an altitude of 3300-3700 m. Circulating levels of LH, FSH, prolactin, cortisol, testosterone, dihydrotestosterone (DHT) and progesterone in ALL at 3542 m and in HAN were not significantly different (p > 0.05) from the SL control values. When the ALL living at 3542 m trekked to an extreme altitude of 5080 m, their testosterone levels showed a significant decrease (p < 0.01) compared to the preceding altitude values but had returned to SL values when measured after 6 months' continuous stay at 6300 m. As with testosterone, the levels of DHT and oestradiol-17 beta (E2) after prolonged stay at extreme altitude were also not significantly different (p > 0.05) from the SL values. The LH levels after trekking to 5080 m were significantly higher (p < 0.01) than at an altitude of 3542 m, but decreased to levels found at 3542 m or SL after prolonged residence at extreme altitude. Plasma levels of ACTH, prolactin, FSH and cortisol on arrival at 5080 m, and after a 6-month stay at extreme altitude, were not significantly different (p > 0.05) from the SL values. Plasma progesterone levels tended to increase on arrival at 5080 m but a significant increase (p < 0.001) was evident only after a 6-month stay at extreme altitude. These observations suggest that prolonged residence at lower as well as at extreme altitude does not appreciably alter blood levels of pituitary, gonadal or adrenal hormones except for plasma levels of progesterone. The exact mechanism and significance of this increase remains unknown, but may be important in increasing the sensitivity of the hypoxic ventilatory response and activation of haemoglobin synthesis.

Trials in school-aged children suggest vitamin D supplementation reduces asthma exacerbations. Primary aim: to examine whether vitamin D3 (100,000 IU) rapidly raises serum 25-hydroxyvitamin D (25OHD) ≥75 nmol/L in asthmatic preschoolers. In a double-blind, randomised, placebo-controlled trial, preschool-aged children with asthma received 100,000 IU vitamin D3 (intervention) or placebo (control), followed by 400 IU vitamin D3 daily for 6 months. Serum 25OHD was measured at baseline, 10 days, 3 and 6 months. Outcomes included the group difference in 25OHD change from baseline at 3 months (Δ25OHD); the proportion of children with 25OHD ≥75 nmol/L at 3 months; the pattern in serum vitamin D over 6 months; the proportion of children with hypercalciuria at any time point (safety); and group rates for oral corticosteroids. Continuous outcomes were analysed using generalised linear mixed models and group rate ratios of events per child were assessed using a Poisson distribution model. Twenty-two children were randomised (intervention:11; control:11) during winter. At 3 months, the group difference in Δ25OHD (7.2 nmol/L; 95 % CI: -13.7, 28.1) was not significant; yet, 100 % versus 54.5 % (intervention versus control) had serum 25OHD ≥75 nmol/L. There was a significant group difference in Δ25OHD at 10 days (110.3 nmol/L; 95 % CI: 64.0, 156.6). One child in each group had transient hypercalciuria at 10 days. Group oral corticosteroids rates were 0.82 and 1.18/child, intervention versus control (rate ratio = 0.68; 95 % CI: 0.30, 1.62; non-significant). Following 100,000 IU vitamin D3, all children reached serum 25OHD ≥75 nmol/L, compared with half who received placebo. Daily supplementation, sun exposure and insufficient power may explain the absence of a significant 3-month group difference in Δ25OHD. No clinically important alterations in bone metabolism biomarkers occurred. Group oral corticosteroid rates will inform sample size calculations for the larger trial.

Primary stability is evaluated using resonance frequency analysis (RFA) and insertion torque (IT). Although there is a strong correlation between RFA and IT, studies failed to find a correlation between RFA and bone to implant contact (BIC) or IT and BIC. To compare RFA, IT, and BIC of SLA, SLActive, Euroteknika, and TiUnite implant surfaces and evaluate the correlation between them. Thirty-two implants were placed in 8 sheep. RFA and IT were recorded. Animals were killed at 1 and 2 months. A significant difference was found in RFA between the 4 surfaces. No significant difference was found for IT. Mean BIC was different between all 4 surfaces. A significant positive correlation was found between RFA and IT with SLA. No significant correlation was found between RFA and BIC and between IT and BIC at 1 and 2 months. Implants with 4 different surfaces have similar IT values but different RFA and BIC. Additionally irrespective of the implant surface, there is no correlation between IT and BIC and between RFA and BIC.

In cooperation with the Lower Platte South Natural Resources District for a collaborative study of the cumulative effects of water and channel management practices on stream and riparian ecology, the U.S. Geological Survey (USGS) compiled, analyzed, and summarized hydrologic information from long-term gaging stations on the lower Platte River to determine any significant temporal differences among six discrete periods during 1895-2006 and to interpret any significant changes in relation to changes in climatic conditions or other factors. A subset of 171 examined hydrologic indices (HIs) were selected for use as indices that (1) included most of the variance in the larger set of indices, (2) retained utility as indicators of the streamflow regime, and (3) provided information at spatial and temporal scale(s) that were most indicative of streamflow regime(s). The study included the most downstream station within the central Platte River segment that flowed to the confluence with the Loup River and all four active streamflow-gaging stations (2006) on the lower Platte River main stem extending from the confluence of the Loup River and Platte River to the confluence of the Platte River and Missouri River south of Omaha. The drainage areas of the five streamflow-gaging stations covered four (of eight) climate divisions in Nebraska?division 2 (north central), 3 (northeast), 5 (central), and 6 (east central). Historical climate data and daily streamflow records from 1895 through 2006 at the five streamflow-gaging stations were divided into six 11-water-year periods: 1895?1905, 1934?44, 1951?61, 1966?76, 1985?95, and 1996?2006. Analysis of monthly climate variables?precipitation and Palmer Hydrological Drought Index?was used to determine the degree of hydroclimatic association between streamflow and climate. Except for the 1895?1905 period, data gaps in the streamflow record were filled by data estimation techniques, and 171 hydrologic indices were calculated using the Hydroecological Integrity Assessment Process software developed by the U.S. Geological Survey. A subset of 27 nonredundant indices (of the 171 indices) was selected using principal component analysis. Indices that described monthly streamflow?mean, maximum, minimum, skewness, and coefficients of variation?also were used. Comparison of these selected indices allowed determination of temporal differences among the six 11-water-year periods for each gaging station. The lower Platte River basin was affected by moderate to severe drought conditions in the 1934?44 period. The widespread drought was preceded by mildly to moderately wet conditions in the 1895?1906 period, followed by incipient drought to incipiently wet conditions in the 1951?61 periods and mildly wet conditions in 1966?76 period, moderately wet conditions in the 1985?1995 period, and incipient drought to mildly wet conditions in the 1996?2006 period. Monthly streamflow of the Platte River from Duncan through Louisville, Nebraska, correlated significantly with the monthly Palmer Hydrological Drought Index. Temporal differences in median values of monthly-mean and monthly-maximum streamflow measured at Duncan, North Bend, and Ashland stations between the two moderately wet periods (1895?1905 and 1985?95) indicated that streamflow storage reservoirs and regulation some time after 1906 significantly reduced monthly streamflow magnitude and amplitude?the difference between the highest and lowest median values of monthly mean streamflow. Effects of storage reservoirs on the median values of monthly-minimum streamflow were less obvious. Temporal differences among the other five periods, from 1934 through 2006 when streamflow was affected by storage and regulation, indicated the predominant effects of contrasting climate conditions on median values of monthly mean, maximum, and minimum streamflow. Significant temporal differences in monthly streamflow values were evident mainly between the two periods of greatly

The serological response to MMR vaccine was evaluated in 109 9-month-old infants having no history of measles vaccination, and in 98 15-month-old children who had received monocomponent measles immunisation at 9 months. The combined vaccine contained Schwarz, Urabe Am9, and Wistar RA 27/3 live attenuated virus strains. Preimmunisation antibody levels were extremely low for the 9-month-old children, indicating that maternally-transmitted antibodies do not persist at this age. In the case of mumps, preimmunisation antibody levels were significantly higher in the 15-month-old than in the 9-month-old group. A difference between groups in terms of postimmunisation antibody titres was observed only for rubella, with titres being significantly higher in the older group. Seroconversion rates were high in both groups and no serious events attributable to vaccination were observed. The MMR vaccine can thus be administered to children as young as 9 months of age. Evidence for the efficacy of a two-dose schedule, i.e. at 9 and 15 months, is presented.

Aiming for minimal toxicity after radical prostate cancer (PC) radiotherapy (RT), magnetic resonance imaging (MRI) target delineation could be a possible benefit knowing that clinical target volumes (CTV) are up to 30% smaller, when CTV delineation on MRI is compared to standard computed tomography (CT). This study compares long-term toxicity using CT or MRI delineation before PC RT. Urinary and rectal toxicity assessments 36 months after image-guided RT (78 Gy) using CTC-AE scores in two groups of PC patients. Peak symptom score values were registered. One group of patients (n=72) had standard CT target delineation and gold markers as fiducials. Another group of patients (n=73) had MRI target delineation and a nickel-titanium stent as fiducial. At 36 months no difference in overall survival (92% in both groups, p=0.29) or in PSA-relapse free survival was found between the groups (MRI=89% and CT=94%, p=0.67). A significantly smaller CTV was found in the MRI group (p=0.02). Urinary retention and frequency were significantly reduced in the MRI group (p=0.03 in the matter of both). The overall urinary and rectal toxicity did not differ between the two groups. MRI delineation leads to a significantly reduced CTV. Significantly lower urinary frequency and urinary retention toxicity scores were observed following MRI delineation. The study did not find significant differences in overall urinary or rectal toxicity between the two groups. PSA-relapse survival did not differ between the two groups at 36 months.

Physiotherapy is an important part of rehabilitation following arthroplasty, but the impact of preoperative physiotherapy on functional outcomes is still being studied. This randomised controlled trial evaluated the effect of preoperative physiotherapy on the short-term functional outcomes of primary total knee arthroplasty (TKA). 50 patients with primary knee osteoarthritis who underwent unilateral primary TKA were randomised into two groups: the physiotherapy group (n = 24), whose patients performed physical exercises for six weeks immediately prior to surgery, and the nonphysiotherapy group (n = 26). All patients went through a similar physiotherapy regime in the postoperative rehabilitation period. Functional outcome assessment using the algofunctional Knee Injury and Osteoarthritis Outcome Score (KOOS) scale and range of motion (ROM) evaluation was performed preoperatively, and postoperatively at six weeks and three months. Both groups showed a significant difference in all algofunctional KOOS subscales (p < 0.001). The mean score difference at six weeks and three months was not significant in the sports and recreational activities subscale for both groups (p > 0.05). Significant differences were observed in the time-versus-treatment analysis between groups for the symptoms (p = 0.003) and activities of daily living (p = 0.025) subscales. No significant difference in ROM was found when comparing preoperative measurements and those at three months following surgery, as well as in time-versus-treatment analysis (p = 0.928). Six-week preoperative physiotherapy showed no significant impact on short-term functional outcomes (KOOS subscales) and ROM of the knee following primary TKA.

Recently, there has been interest in non-mammalian collagen sources such as fish collagen in periodontal regeneration. In the present study, collagen barrier membrane of fish origin was assessed in the treatment of periodontal intrabony defects. Ten systemically healthy chronic periodontitis patients having a paired osseous defect in the mandibular posterior teeth were selected and randomly assigned to receive a collagen membrane (test) or open flap debridement (control) in a split mouth design. Clinical parameters such as Plaque index, Gingival bleeding index, Probing pocket depth, Relative attachment level, and Recession were recorded at baseline, 3, 6, and at 9 months, while radiographic evaluation was done to assess alveolar crestal bone level and percentage of defect fill at 6 and 9 months using autoCAD 2007 software. Student's t test (two-tailed, dependent) was used to find the significance of study parameters on continuous scale. Significance was set at 5% level of significance. Wilcoxon signed rank test was used to find the significance of percentage change of defect fill. The comparison between the two groups did not show any statistically significant differences in the parameters assessed (P > 0.05) but, within each group, clinical parameters showed statistically significant differences from baseline to 9 months (P < 0.05). Within the limits of the study, it can be inferred that no significant differences were found either by using collagen membrane of fish origin or open flap debridement in the treatment of periodontal intrabony defects.

The Southeastern United States has the highest prevalence of hypertension and African Americans have disproportionately worse blood pressure control. The authors sought to evaluate the effect of a multicomponent practice-based quality improvement intervention on lowering mean systolic blood pressure (SBP) at 12 and 24 months compared with baseline among 525 patients, and to assess for a differential effect of the intervention by race (African Americans vs white). At 12 months, both African Americans (-5.0 mm Hg) and whites (-7.8 mm Hg) had a significant decrease in mean SBP compared with baseline, with no significant between-group difference. Similarly, at 24 months, mean SBP decreased in both African Americans (-6.0 mm Hg) and whites (-7.2 mm Hg), with no significant difference between groups. Notably, no significant racial disparity in mean SBP at baseline was shown. The intervention was effective in lowering mean SBP in both African Americans and whites but there was no differential effect of the intervention by race. ©2016 Wiley Periodicals, Inc.

Cigarette smoking is one of the major preventable causes of death and diseases in Qatar. The study objective was to test the effect of a structured smoking cessation program delivered by trained pharmacists on smoking cessation rates in Qatar. A prospective randomized controlled trial was conducted in eight ambulatory pharmacies in Qatar. Eligible participants were smokers 18 years and older who smoked one or more cigarettes daily for 7 days, were motivated to quit, able to communicate in Arabic or English, and attend the program sessions. Intervention group participants met with the pharmacists four times at 2 to 4 week intervals. Participants in the control group received unstructured brief smoking cessation counseling. The primary study outcome was self-reported continuous abstinence at 12 months. Analysis was made utilizing data from only those who responded and also using intent-to-treat principle. A multinomial logistic regression model was fitted to assess the predictors of smoking at 12 months. Analysis was conducted using IBM-SPSS® version 23 and STATA® version 12. A total of 314 smokers were randomized into two groups: intervention (n = 167) and control (n = 147). Smoking cessation rates were higher in the intervention group at 12 months; however this difference was not statistically significant (23.9% vs. 16.9% p = 0.257). Similar results were observed but with smaller differences in the intent to treat analysis (12.6% vs. 9.5%, p = 0.391). Nevertheless, the daily number of cigarettes smoked for those who relapsed was significantly lower (by 4.7 and 5.6 cigarettes at 3 and 6 months respectively) in the intervention group as compared to the control group (p = 0.041 and p = 0.018 respectively). At 12 months, the difference was 3.2 cigarettes in favor of the intervention group but was not statistically significant (p = 0.246). Years of smoking and daily number of cigarettes were the only predictors of smoking as opposed to quitting at 12 months (p = 0.005; p = 0.027 respectively). There was no statistically significant difference in the smoking cessation rate at 12 months between the groups. However, the smoking cessation program led to higher (albeit non-significant) smoking cessation rates compared with usual care. More research should be conducted to identify factors that might improve abstinence. Clinical Trials NCT02123329 . Registration date 20 April 2014.

The objective of this study was to investigate the epidemiological characteristics of disease caused by enterovirus type 71. A total of 10 158 children aged between 6 and 35 months, were recruited from 7 sites where EV71 inactivated vaccine phase 3 clinical trial was carried out. All the subjects were followed up to one year to investigate the epidemiological characteristics of the disease caused by EV71. The accumulate incidence density of disease caused by EV71 was 15.17/1 000 person-year. Of all the cases, hand, foot and mouth disease (HFMD), herpangina, respiratory system diseases, digestive system diseases and other diseases accounted for 82.00%, 2.67%, 13.33%, 1.33% and 0.67%, respectively. The difference of the incidence density between boys and girls showed no statistical significance. Majority of the patients were between 12 and 23 months of age, which accounted for 58.67% of the total patients. The differences of incidence density between different months of age were statistically significant (χ(2) = 7.789, P = 0.020). The peak incidence density of disease caused by EV71 occurred from April to June. Nine cases showed severe symptoms or signs that accounted for 6.00% of all the cases. All severe cases were identified as HFMD, of which 7 were boys and 2 were girls. The number of severe cases in different months of age appeared to be 1, 7, and 1, all occurred between April and June. The median courses of HFMD cases and non-HFMD cases were 9 and 6 days, with difference statistically significant (Z = -4.000, P < 0.001). Median of excretion cycle for HFMD and non-HFMD cases were 9 and 11 days respectively. But with no statistically significant difference between the two. Majority of the disease that caused by EV71 appeared as HFMD. Most of them were younger children and with seasonal variation.

Based on microbiologic concerns, the safety of a 24-month regimen of subantimicrobial dose doxycycline (SDD; 20 mg twice a day) was evaluated in postmenopausal osteopenic women with periodontitis in a double-blind, placebo-controlled, randomized clinical trial. Subgingival samples were collected from two sites (probing depth > or = 5 mm) in each of 128 subjects at baseline, with the same sites resampled at the conclusion of the 2-year period. The samples were enumerated on selective and non-selective media and on doxycycline (4 microg/ml) medium. Up to five different colonial morphologies were subcultured from the doxycycline medium, identified to species, and susceptibilities determined to doxycycline and five other antibiotics. Data were analyzed for microbial differences in total colony forming units (CFU), periodontal and opportunistic pathogens, and changes in species and in susceptibilities of isolates recovered on doxycycline medium. There was no significant evidence that changes in total anaerobic counts over the treatment period (P = 0.96) differed between treatment groups. Likewise, periodontal pathogens, opportunistic pathogens, or normal flora did not differ descriptively between groups. Although there was a significant increase (P <0.001) in the total CFU recovered from the 4 microg/ml doxycycline plates at 24 months for SDD versus placebo, the percentage that was clinically resistant to doxycycline (minimal inhibitory concentration [MIC] > or = 16 microg/ml) decreased over the 24-month period in both groups and did not differ between the treatment groups (SDD: 79% to 76%; placebo: 83% to 70%; P = 0.2). There were no significant differences (P >0.28 for each) in the change in cross-resistance between the groups for doxycycline and the other five antibiotics. No antimicrobial effect on the subgingival flora was detected following treatment with SDD for 24 months, relative to baseline or to placebo. The increase in initial resistance (at 4 microg/ml) did not translate into a significant increase in the percent resistant to doxycycline (MIC > or = 16 microg/ml) for patients in the SDD group.

Purpose To evaluate the response of intravitreal aflibercept injection (IAI) in eyes with detachment of retinal pigment epithelium (DEP) secondary to nAMD refractory to monthly ranibizumab. Patients and Methods This is a retrospective, multicenter study. All patients received 3 IAI then treated as needed every 4 weeks for 12 months. During the second year, the eyes were treated with a treat- and-extend regimen. Results Forty-four eyes were included. Best-corrected visual acuity improved significantly after the loading phase (3.1 ± 6.4 letters) and at 6 months (2.8 ± 6.4 letters), but change was not significant at 1 year and 2 years. The height of the DEP was significantly decreased at 3 months and 6 months, but the difference did not reach statistical difference at 1 and 2 years. Rate of eyes with complete resolution of exudation was 59% after the loading phase and 34.3% at 2 years. Mean interval of anti-VEGF injection was extended from 31 ± 2.6 days to 61 ± 5 days after conversion. Conclusions Aflibercept intravitreal injection in patients with fibrovascular DEP due to nAMD who respond poorly to monthly ranibizumab led to short-term functional and anatomical improvement. Reduction of intravitreal injection frequency was obtained until 2 years of follow-up. PMID:29093970

To investigate the effects on muscle performance after one-year cessation of 18-month low-magnitude high-frequency vibration (LMHFV) intervention in the untrained community elderly. This is a case-control study with 59 community elderly women (25 control without any treatment; 34 received 18-month LMHFV but discontinued for 1 year from our previous clinical study). Muscle strength, balancing ability, occurrence of fall/fracture, quality of life (QoL) were assessed 1-year after cessation of intervention. The 30-month results were compared with baseline and 18-month treatment endpoint data between groups. At 30 months (i.e. one year post-intervention), the muscle strengths of dominant and non-dominant legs relative to baseline in treatment group were significantly better than those of control. In balancing ability test, reaction time, movement velocity and maximum excursion of treatment group (relative to baseline) remained significantly better than the control group. The muscle strength, balancing ability and quality of life at 30 months relative to 18 months did not show significant differences between the two groups. The benefits of LMHFV for balancing ability, muscle strength and risk of falling in elderly were retained 1 year after cessation of LMHFV.

To better understand the role of motivation in determining exercise participation at the population level, we performed a questionnaire survey of 385 Japanese adults (mean age: 55.0 years, SD: 10.9 years). At baseline, the motivation subscales (intrinsic motivation, identified regulation, and external regulation), self-efficacy, and enjoyment all showed significant differences across the stages of change for exercise. Intrinsic motivation and enjoyment had similar findings, with the highest scores being noted in the maintenance stage. Among the 385 subjects, 183 completed the follow-up questionnaire 3 months later. After 3 months, most of the participants (86.9%) who were in the maintenance stage at baseline remained in the same stage. The number of participants who dropped to a lower stage after 3 months was 23. The changes of exercise stage over the 3-month period differed significantly for identified regulation, introjected regulation, and motivation. There were significant time and group interactions for intrinsic motivation and identified regulation. These findings suggest the importance of intrinsic motivation and identified regulation for performance of regular exercise, as well as the role of introjected regulation for promoting behavioral change among Japanese adults.

Purpose/Objectives To identify and compare levels of distress and sources of problems among patients with breast cancer in early survivorship. Design Descriptive, cross-sectional. Setting A National Cancer Institute–designated comprehensive cancer center. Sample 100 breast cancer survivors were selected to represent four time points in the cancer trajectory. Methods Distress was self-reported using the Distress Thermometer and its 38-item problem list. Analysis of variance and chi-square analyses were performed as appropriate. Main Research Variables Distress scores, problem reports, and time groups. Findings Participants scored in range of the cutoff of more than 4 (range = 4.1–5.1) from treatment through three months post-treatment. At six months post-treatment, distress levels were significantly lower. Significant differences were found between groups on the total problem list score (p = 0.007) and emotional (p = 0.01) and physical subscale scores (p = 0.003). Conclusions Comparison of groups at different points in the cancer trajectory found similar elevated levels from diagnosis through three months. Distress remained elevated in early survivorship but significantly decreased at six months post-treatment. Implications for Nursing Interventions to reduce or prevent distress may improve outcomes in early survivorship. PMID:25542330

Purpose To compare the preoperative and postoperative bilateral symmetry between OD and OS eyes that have undergone femto-LASIK using the Ziemer LDV femtosecond laser system, the SCHWIND AMARIS Excimer Laser and the Aberrationfree™ profiles implemented in the SCHWIND Custom Ablation Manager software. Methods A total of 25 LASIK patients were bilaterally evaluated at the six-month follow-up visit. In all cases standard examinations, pre- and postoperative analysis with corneal wavefront topography (OPTIKON Scout) were performed. Aberration-free™ aspheric treatments were devised using the Custom Ablation Manager software and ablations were performed by means of the SCHWIND AMARIS flying-spot excimer laser system (both SCHWIND eyetech- solutions). In all cases LASIK flaps were created using an LDV femtosecond laser (Ziemer Group). The OD/OS bilateral symmetry was evaluated in terms of corneal wavefront aberration. Results Preoperatively, 11 Zernike terms showed significant bilateral (OS-vs.-OD) symmetry, and only 6 Zernike terms were significantly different. Overall, 23 out of the 25 patients showed significant bilateral symmetry, and only 2 out of 25 patients showed significant differences. None of the aberration metrics changed from pre- to postoperative values by a clinically relevant amount. At the 6-month postoperative visit, 12 Zernike terms showed significant symmetry, and 8 terms were significantly different. Overall, 22 out of 25 patients showed significant bilateral symmetry (OS vs. OD), and only 3 out of 25 patients showed significant differences. Also, this postoperative examination revealed that 6 Zernike terms lost significant OS-vs.-OD symmetry, but 4 Zernike terms gained significant symmetry. Finally, 4 patients lost significant bilaterality, and 2 patients gained significant bilaterality: bilateral symmetry between eyes was better maintained in those patients with a clear preoperative bilateral symmetry. Conclusions Aberration-Free Treatments with the SCHWIND AMARIS did not induce clinically significant aberrations, maintained the global OD-vs.-OS bilateral symmetry, as well as the bilateral symmetry between corresponding Zernike terms (which influences binocular summation).

To study the efficacy of silicone gel applied to hypertrophic burn scars, in reducing scar interference with normal function and improving cosmesis. A randomised, double-blind, placebo-controlled trial involving 38 people with hypertrophic burn scars. Each scar was divided into two segments; silicone gel sheet was applied randomly to one of the two and placebo to the other. Participants were seen again after 1 and 4 months. Their data and wound characteristics were collected using the Vancouver scar scale. The median age of participants was 22 years (1.5-60 years) and 16 were male; 4 did not attend follow-up and were excluded from the study. There were no significant differences in baseline characteristics. Although after 1 month all scar scale measures were lower in treated areas, only the vascularity scale was significantly different between the two areas. After 4 months, all scale measures were significantly lower in the silicone gel group than in the control group, except for the pain score. Silicone gel is an effective treatment for hypertrophic burn scars.

To compare the growth and development of children born to mothers with gestational diabetes mellitus (GDM) requiring pharmacological treatment, and randomised to treatment with metformin or insulin. Follow-up of a randomised controlled trial (RCT) comparing metformin and insulin treatment of GDM. Data were gathered during routine visits to child welfare clinics at the ages of 6, 12, and 18 months, including weight and height measurements, and assessment of motor, social, and linguistic development. The children of mothers with GDM randomised to metformin (n = 47) or insulin (n = 50) treatment during pregnancy. Data were collected from the structured questionnaire filled in at the child welfare clinics. The growth and development of the children until the age of 18 months. Children exposed to metformin were significantly heavier (10.47 versus 9.85 kg, 95% CI 0.04-1.20) at the age of 12 months and taller and heavier (83.9 vs 82.2 cm, 95% CI 0.23-3.03, 12.05 vs 11.32 kg, 95% CI 0.04-1.43) at the age of 18 months. The mean ponderal index (PI) did not differ significantly. The motor, social, or linguistic development evaluated at the age of 18 months did not differ between the groups. Children prenatally exposed to metformin were heavier at the 12 months measurements and taller and heavier at the 18 months measurements than those exposed to insulin, but their body composition defined by PI did not differ. Over the short term, metformin does not seem to be harmful with regards to early motor, linguistic, or social development. © 2014 Royal College of Obstetricians and Gynaecologists.

To evaluate prospectively the efficacy and safety of a fixed bimonthly ranibizumab treatment regimen (RABIMO) in eyes with neovascular age-related macular degeneration (nAMD) and to compare these results with a pro re nata (PRN) treatment scheme. This was a 12-month, phase IV, single center, randomised, non-inferiority study. Following three initial monthly injections, patients were randomised to receive either ranibizumab bimonthly (RABIMO group) or ranibizumab PRN (PRN group) (n = 20 each). Main outcome measures were best-corrected visual acuity (BCVA), central retinal thickness (CRT), number of injections, and adverse events (AEs). BCVA [median (interquartile range, IQR)] increased significantly in both groups after 12 months [RABIMO group +8.5 (14); PRN group +6.5 (16) ETDRS letters] when compared to baseline (p < 0.0001; p = 0.0085). At month 12, the RABIMO treatment regimen was non-inferior to the PRN scheme (∆BCVA = 3.5 ETDRS letters; p < 0.0001). CRT was significantly reduced in both groups after the 12-month study period (p < 0.0001 each), with no significant difference between groups (p = 0.6772). Number of overall injections [median (IQR)] was 8 (0) in the RABIMO versus 4 (5) in the PRN group (p = 0.0037). Three patients in the RABIMO group received one additional unscheduled injection. We observed no significant differences between groups in the number of patients with reported SAEs/AEs (RABIMO group n = 6/15; PRN group n = 7/13) (p = 0.7357/p = 0.4902). We found no evidence of significant functional or anatomical differences between the RABIMO and PRN treatment regimens. However, the RABIMO group's number of injections was twice as high as the PRN group's (protocol-driven). In light of potential side effects, the fixed bimonthly treatment regimen might not be advisable for routine clinical care, but it might be a worthwhile treatment option if monthly monitoring is not possible.

Background The balANZ trial recently reported that neutral pH, low glucose degradation product (biocompatible) peritoneal dialysis (PD) solutions significantly delayed anuria and reduced peritonitis rates compared with conventional solutions. This article reports a secondary outcome analysis of the balANZ trial with respect to peritoneal membrane function. Methods Adult, incident PD patients with residual renal function were randomized to receive either biocompatible or conventional (control) PD solutions for 2 years. Peritoneal equilibration tests were performed at 1, 6, 12, 18 and 24 months. Peritoneal small solute clearances and ultra-filtration (UF) were measured at 3, 6, 9, 12, 18 and 24 months. Results Of the 185 patients recruited into the trial, 85 patients in the Balance group and 82 patients in the control group had peritoneal membrane function evaluated. Mean 4-h dialysate:plasma creatinine ratios (D:P Cr 4h) at 1 month were significantly higher in the Balance group compared with controls (0.67 ± 0.10 versus 0.62 ± 0.10, P = 0.002). Over the 2-year study period, mean D:P Cr 4 h measurements remained stable in the Balance group but increased significantly in controls [difference −0.004 per month, 95% confidence interval (95% CI) −0.005 to −0.002, P < 0.001]. Similar results were obtained for dialysate glucose ratios (D/D0 glucose). Peritoneal UF was significantly lower in the Balance group than in controls at 3 and 6 months. Over the 2-year study period, peritoneal UF increased significantly in the Balance group but remained stable in controls (difference 24 mL/day/month, 95% CI 9–39, P = 0.002). No differences in peritoneal small solute clearances, prescribed dialysate fill volumes or peritoneal glucose exposure were observed between the two groups. Conclusions Biocompatible and conventional PD solutions exert differential effects on peritoneal small solute transport rate and UF over time. Adequately powered trials assessing the impact of these differential membrane effects on PD technique and patient survival rates are warranted. PMID:22859794

Purpose: To compare dosimetric parameters, seed migration rates, operation times, and acute toxicities of intraoperatively built custom-linked (IBCL) seeds with those of loose seeds for prostate brachytherapy. Methods and Materials: Participants were 140 patients with low or intermediate prostate cancer prospectively allocated to an IBCL seed group (n=74) or a loose seed group (n=66), using quasirandomization (allocated by week of the month). All patients underwent prostate brachytherapy using an interactive plan technique. Computed tomography and plain radiography were performed the next day and 1 month after brachytherapy. The primary endpoint was detection of a 5% difference in dose to 90% ofmore » prostate volume on postimplant computed tomography 1 month after treatment. Seed migration was defined as a seed position >1 cm from the cluster of other seeds on radiography. A seed dropped into the seminal vesicle was also defined as a migrated seed. Results: Dosimetric parameters including the primary endpoint did not differ significantly between groups, but seed migration rate was significantly lower in the IBCL seed group (0%) than in the loose seed group (55%; P<.001). Mean operation time was slightly but significantly longer in the IBCL seed group (57 min) than in the loose seed group (50 min; P<.001). No significant differences in acute toxicities were seen between groups (median follow-up, 9 months). Conclusions: This prospective quasirandomized control trial showed no dosimetric differences between IBCL seed and loose seed groups. However, a strong trend toward decreased postimplant seed migration was shown in the IBCL seed group.« less

Post-acute community-based rehabilitation is effective in reducing disability. However, while social participation and quality of life are valued as distal outcomes of neurorehabilitation, it is often not possible to observe improvements on these outcomes within the limited time-frames used in most investigations of rehabilitation. The aim of the current study was to examine differences in the sequence of attainments for people with acquired brain injury (ABI) undergoing longer term post-acute neurorehabilitation. Participants with ABI who were referred to comprehensive home and community-based neurorehabilitation were assessed at induction to service, at 6 months and again at 1.5 years while still in service on the Mayo-Portland Adaptability Index (MPAI-4), Community Integration Questionnaire, Hospital Anxiety and Depression Scale, and World Health Organisation Quality of Life measure. At 6 months post-induction to service, significant differences were evident in MPAI abilities, adjustment, and total neurodisability; and in anxiety and depression. By contrast, there was no significant effect at 6 months on more socially oriented features of experience namely quality of life (QoL), Community Integration and Participation. Eighteen month follow-up showed continuation of the significant positive effects with the addition of QoL-related to physical health, Psychological health, Social aspects of QoL and Participation at this later time point. Regression analyses demonstrated that change in QoL and Participation were dependent upon prior changes in aspects of neurodisability. Age, severity or type of brain injury did not significantly affect outcome. Results suggest that different constructs may respond to neurorehabilitation at different time points in a dose effect manner, and that change in social aspects of experience may be dependent upon the specific nature of prior neurorehabilitation attainments.

Laser systems that are commonly used for the treatment of hirsutism include the ruby laser (694 nm), the diode laser (800 nm), the alexandrite laser (755 nm) and the Nd:YAG laser (1084 nm). The diode laser and alexandrite laser are considered effective in treatment of hirsutism in dark-skinned patients. The response of hairs to these laser systems is variable and not complete. In this study, we compared the efficacy of these two laser systems for permanent hair removal. This was a randomized, controlled clinical trial that was performed with women of the age range 15-45 years old. After obtaining informed consent, the samples were randomized into two groups using random allocation software. The first group was treated with alexandrite laser alone (four sessions, two months apart). The second group was treated sequentially with diode laser for the first two sessions and alexandrite laser for the next two sessions. Overall, 111 patients (57 patients in the alexandrite laser group and 54 patients in the sequential diode-alexandrite laser group) were evaluated. There was no significant difference regarding mean of hair reduction between the two groups during the courses of treatment. Except for the first session, there was no significant difference regarding percent of patient satisfaction between the two groups (P value >0.05). Comparison between the two groups showed no significant difference one month, three months and six months after the last treatment (P value >0.05). Regarding the results of our study, there is no significant difference between sequential treatment with diode and alexandrite lasers versus alexandrite laser alone in the treatment of hirsutism. We suggest that in further studies, the efficacy of sequential treatment with other laser systems is evaluated against single treatment methods.

This study's purpose was to analyze the effect of the SmartCare pilot project, which was conducted in 2011 in South Korea. Recent studies of telehealth mostly compare the intervention group and the control group. Therefore, it is necessary to analyze the disease improvement effect depending on the self-measurement compliance (measurement frequency level) of patients who are receiving the hypertension management services. In the SmartCare center, health managers (nurses, nutritionists, and exercise prescribers) monitored the measurement data transmitted by participants through the SmartCare system. The health managers provided the prevention, consultation, and education services remotely to patients. Of the 231 participants who were enrolled in the study, the final analysis involved 213 individuals who completed their blood pressure measurements and SmartCare services until the end of a 6-month service period. The evaluated measurement group was classified into three groups (Low, Middle, and High) by evenly dividing the monthly average frequency of measurement for 6 months. The evaluation indices were systolic blood pressure (SBP), diastolic blood pressure (DBP), weight, and body mass index (BMI); this information was transmitted through the SmartCare system. For changes in the evaluation indices after 6 months compared with the initial baseline, in the Low Group, SBP and DBP slightly decreased, and weight and BMI slightly increased (difference not statistically significant). In the Middle Group, SBP and DBP decreased slightly (difference not statistically significant); however, both weight and BMI decreased (difference statistically significant). In the High Group, SBP, DBP, weight, and BMI decreased (difference statistically significant). Patients who received the SmartCare services with higher measurement frequency levels at home showed greater effectiveness regarding the provided services compared with those patients with lower levels of BP, weight, and BMI control.

To assess the impact of sequential and combined surgery [cataract surgery and 23-gauge pars plana vitrectomy (PPV) with peeling] on corneal endothelium cell density (CED) and corneal biomechanical characteristics. Phakic eyes with epiretinal membrane (ERM) were prospectively allocated to (i) cataract surgery and subsequent PPV (CAT group), (ii) PPV and subsequent cataract surgery (VIT group) or (iii) phacovitrectomy (COMBI group). Eyes were examined at baseline, 1 month after each surgery, and at 3 and 12 months follow-up. Corneal endothelium cell density (CED) was assessed with non-contact specular microscopy. Pachymetry [central cornea thickness (CCT)], keratometry and cornea volume (CV) were measured with Pentacam Scheimpflug camera. Primary outcome was change in CED after 12 months; secondary outcomes were changes in CCT and CV after 12 months. Sixty-two eyes were enrolled and allocated to the three groups. The mean preoperative CED was 2776, 2794 and 2653 cells/mm 2, which decreased significantly at 12 months by 15.3, 20.0 and 19.3% in the CAT, VIT and COMBI group. There was no significant difference in percentage cell loss between the groups at final follow-up. The CED decreased significantly after cataract surgery, but was unaffected by PPV. Central cornea thickness (CCT) increased by 10 μm (p = 0.005) and CV by 1.38 mm 3 (2.3%, p < 0.001) in the COMBI group. There were no significant differences in CCT or CV between the groups at final follow-up. Combined and sequential surgery in ERM leads to a small decrease in CED. Performing cataract surgery before, after or in combination with vitrectomy did not make any significant difference with respect to final CED, CCT or CV. © 2017 Acta Ophthalmologica Scandinavica Foundation.

The respondent were primary school students aged 6-8 years, from primary school in Kukusan, Depok, West Java, Indonesia. They were screened of dental examination and the total number of 296 children with an age range of 6-8 year old were included in the study. All students who had dentin caries were get dental treatment with propolis fluoride topical application in dentin caries surface. After one month, two months and four months all students who were got propolis fluoride topical application in dentin caries surface were controlled. All data were analyzed by Wilcoxon test. The total number of dentinal decay of 296 student was 1740 surfaces indicated to Flolis topical application. After one, two and three months of Flolis application, all arrested of dentinal decay was evaluated, the result of evaluation from the second month to the third month evaluation was found that the arrested dentinal caries surfaces were decreased significantly at 29.36% (p<0.01), while the evaluation of arrested dentinal caries surface from the first month to the third month was decreased significantly at 38.62% (p<0.001). Flolis was proven significantly to be able to arrest the activity of dental caries, and their ability to arrest dental caries was significantly different. Flolis was found to be effective in arresting dentinal caries surface until three months application, and should be repeated after 3 months of Flolis application.

The Mayo clinic participated in the Depression Improvement Across Minnesota, Offering a New Direction model at two Mayo Family Clinics, that is, the Rochester Northwest and Northeast sites. Although the Northwest and Northeast clinics demonstrated the best 6-month remission rates in the state during the first year of implementation, they were retrospectively found to differ on several process issues and on measures related to the populations served. Six-month remission rates were significantly better at Northwest clinic; yet, Northeast clinic had more patient contacts. Differences in rates of activation into care management, care management accessibility, and differences in maintaining contact with patients at 6 months may explain some of these results.

Previously, we reported on bone histomorphometry, biochemical markers, and bone mineral density distribution after 6 and 24 months of treatment with teriparatide (TPTD) or zoledronic acid (ZOL) in the SHOTZ study. The study included a 12-month primary study period, with treatment (TPTD 20 μg/d by subcutaneous injection or ZOL 5 mg/yr by intravenous infusion) randomized and double-blind until the month 6 biopsy (TPTD, n = 28; ZOL, n = 30 evaluable), then open-label, with an optional 12-month extension receiving the original treatment. A second biopsy (TPTD, n = 10; ZOL, n = 9) was collected from the contralateral side at month 24. Here we present data on remodeling-based bone formation (RBF), modeling-based bone formation (MBF), and overflow modeling-based bone formation (oMBF, modeling overflow adjacent to RBF sites) in the cancellous, endocortical, and periosteal envelopes. RBF was significantly greater after TPTD versus ZOL in all envelopes at 6 and 24 months, except the periosteal envelope at 24 months. MBF was significantly greater with TPTD in all envelopes at 6 months but not at 24 months. oMBF was significantly greater at 6 months in the cancellous and endocortical envelopes with TPTD, with no significant differences at 24 months. At 6 months, total bone formation surface was also significantly greater in each envelope with TPTD treatment (all p < 0.001). For within-group comparisons from 6 to 24 months, no statistically significant changes were observed in RBF, MBF, or oMBF in any envelope for either the TPTD or ZOL treatment groups. Overall, TPTD treatment was associated with greater bone formation than ZOL. Taken together the data support the view that ZOL is a traditional antiremodeling agent, wheareas TPTD is a proremodeling anabolic agent that increases bone formation, especially that associated with bone remodeling, including related overflow modeling, with substantial modeling-based bone formation early in the course of treatment. © 2017 American Society for Bone and Mineral Research. © 2017 American Society for Bone and Mineral Research.

To determine whether topical corticosteroids as adjunctive therapy for bacterial keratitis improves long-term clinical outcomes. Randomized, placebo-controlled, double-masked clinical trial. This multicenter trial compared 1.0% prednisolone sodium phosphate to placebo in the treatment of bacterial keratitis among 500 patients with culture-positive ulcers receiving 48 hours of moxifloxacin before randomization. The primary endpoint was 3 months from enrollment, and 399 patients were evaluated at 12 months. The outcomes examined were best spectacle-corrected visual acuity (BSCVA) and scar size at 12 months. Based on previous results, regression models with adjustments for baseline status and/or causative organism were used for analysis. No significant differences in clinical outcomes by treatment group were seen with the prespecified regression models (BSCVA: -0.04 logMAR, 95% CI, -0.12 to 0.05, P = .39; scar size: 0.03 mm, 95% CI, -0.12 to 0.18, P = .69). A regression model including a Nocardia-treatment arm interaction found corticosteroid use associated with a mean 1-line improvement in BSCVA at 12 months among patients with non-Nocardia ulcers (-0.10 logMAR, 95% CI, -0.19 to -0.02, P = .02). No significant difference was observed in 12-month BSCVA for Nocardia ulcers (0.18 logMAR, 95% CI, -0.04 to 0.41, P = .16). Corticosteroids were associated with larger mean scar size at 12 months among Nocardia ulcers (0.47 mm, 95% CI, 0.06-0.88, P = .02) and no significant difference was identified by treatment for scar size for non-Nocardia ulcers (-0.06 mm, 95% CI, -0.21 to 0.10, P = .46). Adjunctive topical corticosteroid therapy may be associated with improved long-term clinical outcomes in bacterial corneal ulcers not caused by Nocardia species. Copyright © 2014 Elsevier Inc.

Vascularity is the important factor of biologic healing of the repaired tissue. The purpose of this study was to clarify sequential vascular patterns of repaired rotator cuff by suture techniques. We randomized 21 shoulders in 20 patients undergoing arthroscopic rotator cuff repair into 2 groups: transosseous-equivalent repair (TOE group, n = 10) and transosseous repair (TO group, n = 11). Blood flow in 4 regions inside the cuff (lateral articular, lateral bursal, medial articular, and medial bursal), in the knotless suture anchor in the TOE group, and in the bone tunnel in the TO group was measured using contrast-enhanced ultrasound at 1 month, 2 months, 3 months, and 6 months postoperatively. The sequential vascular pattern inside the repaired rotator cuff was different between groups. The blood flow in the lateral articular area at 1 month, 2 months, and 3 months (P = .002, .005, and .025) and that in the lateral bursal area at 2 months (P = .031) in the TO group were significantly greater than those in the TOE group postoperatively. Blood flow was significantly greater for the bone tunnels in the TO group than for the knotless suture anchor in the TOE group at 1 month and 2 months postoperatively (P = .041 and .009). This study clarified that the sequential vascular pattern inside the repaired rotator cuff depends on the suture technique used. Bone tunnels through the footprint may contribute to biologic healing by increasing blood flow in the repaired rotator cuff. Copyright © 2017 Journal of Shoulder and Elbow Surgery Board of Trustees.

Osteoarthritis (OA) is a debilitating disease resulting in substantial pain and functional limitations. A novel blood derivative has been developed to concentrate both growth factors and antagonists of inflammatory cytokines, with promising preliminary findings in terms of safety profile and clinical improvement. To investigate if one intra-articular injection of autologous protein solution (APS) can reduce pain and improve function in patients affected by knee OA in a multicenter, randomized, double-blind, saline-controlled study. Randomized controlled trial; Level of evidence, 2. Forty-six patients with unilateral knee OA (Kellgren-Lawrence 2 or 3) were randomized into the APS group (n = 31), which received a single ultrasound-guided injection of APS, and the saline (control) group (n = 15), which received a single saline injection. Patient-reported outcomes and adverse events were collected at 2 weeks and at 1, 3, 6, and 12 months through visual analog scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Knee injury and Osteoarthritis Outcome Score (KOOS), Short Form-36 (SF-36), Clinical Global Impression of Severity/Change (CGI-S/C), Patient Global Impression of Severity/Change (PGI-S/C), and Outcome Measures in Rheumatology-Osteoarthritis Research Society International (OMERACT-OARSI) responder rate. Imaging evaluation was also performed with radiograph and magnetic resonance imaging (MRI) before and after treatment (12 months and 3 and 12 months, respectively). The safety profile was positive, with no significant differences in frequency and severity of adverse events between groups. The improvement from baseline to 2 weeks and to 1, 3, and 6 months was similar between treatments. At 12 months, improvement in WOMAC pain score was 65% in the APS group and 41% in the saline group ( P = .02). There were no significant differences in VAS pain improvement between groups. At 12 months, APS group showed improved SF-36 Bodily Pain subscale ( P = .0085) and Role Emotional Health subscale ( P = .0410), as well as CGI-C values ( P = .01) compared with saline control. Significant differences between groups were detected in change from baseline to 12 months in bone marrow lesion size as assessed on MRI and osteophytes in the central zone of the lateral femoral condyle, both in favor of the APS group ( P = .041 and P = .032, respectively). There were no significant differences between APS and control groups in other measured secondary endpoints. This study provides evidence to support the safety and clinical improvement at 1-year follow-up of a single intra-articular injection of APS in patients affected by knee OA. Treatment with APS or a saline injection provided significant pain relief over the course of the study with differences becoming apparent at between 6 and 12 months after treatment.

Azilsartan is an angiotensin II receptor blocker with a potent antihypertensive effect. In a multicenter, prospective, open-label study, 265 patients with poor blood pressure control despite treatment with other angiotensin II receptor blockers were switched to 20 mg/day of azilsartan (patients on standard dosages) or 40 mg/day of azilsartan (patients on high dosages). Blood pressure was 149/83 mm Hg before switching and was significantly reduced from 1 month after switching until final assessment (132/76 mm Hg, P < 0.001). The pulse rate was 72/min before switching and increased significantly from 3 months after switching until final assessment (74/min, P < 0.005). A significant decrease of home morning systolic and diastolic pressure was observed from 1 and 3 months, respectively. Home morning blood pressure was 143/82 mm Hg before switching and 130/76 mm Hg at final assessment (P < 0.01). The morning-evening difference of systolic blood pressure decreased from 14.6 to 6.6 mm Hg after switching (P = 0.09). The estimated glomerular filtration rate was significantly decreased at 3, 6, and 12 months after switching, and serum uric acid was significantly increased at 12 months. No serious adverse events occurred. Azilsartan significantly reduced the blood pressure and decreased diurnal variation in patients responding poorly to other angiotensin II receptor blockers.

Reber, Monika Bertges; Kompis, Martin

To study auditory acclimatization and outcome in first time hearing aid users fitted with state of the art hearing aids as a function of different hearing aid fitting protocols. Twenty-eight adult subjects participated in the study. Each subject was assigned to one of three study groups (named audiologist driven, AD; patient driven, PD; set-to-target, STT according to the fitting protocol used) and fitted with digital hearing aids (Bernafon Symbio). Speech recognition scores were measured in aided and unaided conditions over a 6-month period. Five subjects (three from the PD-group, two from the STT group) decided to withdraw from the study during the 6-month-study period, leaving a total of 23 complete data sets for analysis. Aided speech understanding increased significantly over this time period in all three groups. However, average hearing aid insertion gain changes were small over the same period. There were no statistically significant differences in aided or unaided speech recognition scores between the three groups after 2 weeks or after 6 months. On average, twice as many fine tunings of the hearing aids were requested by the patients in the AD and the STT group than in the PD group and subjects in the AD and STT group used their hearing aids approximately twice as much as subjects in the PD group. The substantial increase in speech intelligibility without significant changes of the insertion gain of the hearing aids over a 6-month period in all three groups suggests a significant acclimatization effect. Although the speech recognition with hearing aids did not differ significantly among the three study groups after 6 months, the lower average wearing time and the higher number of withdrawals from the study in the PD group suggest that the patients' needs are not adequately met. In terms of aided speech recognition scores and hearing aid wearing time the STT group and the AD group were very similar. However, comments of the patients and the higher rate of withdrawals in the STT group suggest an over-all advantage for the AD fitting protocol.

Objectives: To investigate the relation between occlusal loading and peri-implant clinical parameters (probing depth, bleeding on probing, gingival retraction, width of keratinized mucosa, and crevicular fluid volume) in patients with implant-supported complete fixed prostheses in both arches. Material and Methods: This clinical study took place at the University of Valencia (Spain) dental clinic. It included patients attending the clinic for regular check-ups during at least 12 months after rehabilitation of both arches with implant-supported complete fixed ceramo-metallic prostheses. One study implant and one control implant were established for each patient using the T-Scan®III computerized system (Tesco, South Boston, USA). The maxillary implant closest to the point of maximum occlusal loading was taken as the study implant and the farthest (with least loading) as the control. Occlusal forces were registered with the T-Scan® III and then occlusal adjustment was performed to distribute occlusal forces correctly. Peri-implant clinical parameters were analyzed in both implants before and two and twelve months after occlusal adjustment. Results: Before occlusal adjustment, study group implants presented a higher mean volume of crevicular fluid (51.3±7.4 UP) than the control group (25.8±5.5 UP), with statistically significant difference. Two months after occlusal adjustment, there were no significant differences between groups (24.6±3.8 UP and 26±4.5 UP respectively) (p=0.977). After twelve months, no significant differences were found between groups (24.4±11.1 UP and 22.5±8.9 UP respectively) (p=0.323). For the other clinical parameters, no significant differences were identified between study and control implants at any of the study times (p>0.05). Conclusions: Study group implants receiving higher occlusal loading presented significantly higher volumes of crevicular fluid than control implants. Crevicular fluid volumes were similar in both groups two and twelve months after occlusal adjustment. Key words:Occlusal loading, crevicular fluid, peri-implant clinical parameters, T-Scan®.

Proton pump inhibitors (PPIs) are a widely used class of drugs because of a generally acceptable safety profile. Among recently raised safety issues of the long-term use of PPIs is the increased risk of developing hypomagnesemia. As there have been very few prospective studies measuring serum magnesium levels before and after PPI therapy, we aimed to prospectively assess the potential association between PPI therapy for 12 months and the risk of hypomagnesemia as well as the incidence of new-onset hypomagnesemia during the study. In addition, the association of PPI therapy with the risk of hypocalcemia was assessed. The study included 250 patients with normal serum magnesium and total calcium levels, who underwent a long-term PPI treatment. Serum magnesium, total calcium, and parathormone (PTH) levels were measured at baseline and after 12 months. Of the 250 study participants, 209 completed 12 months of treatment and were included in the statistical analysis. The Wilcoxon signed rank test showed no statistically significant differences in serum magnesium levels between measurements at two different time points. However, there were statistically significant differences in serum total calcium and PTH levels in PPI users. Stable serum magnesium levels were demonstrated after 12 months and no association between PPI use and risk of hypomagnesemia was shown in the general population. Significant reductions of serum total calcium levels were demonstrated among PPI users; nevertheless, further research is required before recommending any serum calcium and PTH level monitoring in patients initiated on long-term PPI therapy.

Sucrose is considered by many to be detrimental to health, giving rise to deterioration of the body associated with ageing. This study was undertaken to determine whether replacing sucrose in the diet long-term with honey that has a high antioxidant content could decrease deterioration in brain function during ageing. Forty-five 2-month old Sprague Dawley rats were fed ad libitum for 52 weeks on a powdered diet that was either sugar-free or contained 7.9% sucrose or 10% honey (which is the equivalent amount of sugar). Anxiety levels were assessed using an Elevated Plus Maze, whilst a Y maze and an Object Recognition task were used to assess memory. Locomotor activity was also measured using an Open Field task to ensure that differences in activity levels did not bias results in the other tasks. Anxiety generally decreased overall from 3 to 12 months, but the honey-fed rats showed significantly less anxiety at all stages of ageing compared with those fed sucrose. Honey-fed animals also displayed better spatial memory throughout the 12-month period: at 9 and 12 months a significantly greater proportion of honey-fed rats recognised the novel arm as the unvisited arm of the maze compared to rats on a sugar-free or sucrose-based diet. No significant differences among groups were observed in the Object Recognition task, and there appeared to be no differences in locomotor activity among groups at either 6 or 12 months. In conclusion, it appears that consumption of honey may reduce anxiety and improve spatial memory in middle age.

Whether arthroscopic partial meniscectomy for symptomatic patients with a meniscal tear and knee osteoarthritis results in better functional outcomes than nonoperative therapy is uncertain. We conducted a multicenter, randomized, controlled trial involving symptomatic patients 45 years of age or older with a meniscal tear and evidence of mild-to-moderate osteoarthritis on imaging. We randomly assigned 351 patients to surgery and postoperative physical therapy or to a standardized physical-therapy regimen (with the option to cross over to surgery at the discretion of the patient and surgeon). The patients were evaluated at 6 and 12 months. The primary outcome was the difference between the groups with respect to the change in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) physical-function score (ranging from 0 to 100, with higher scores indicating more severe symptoms) 6 months after randomization. In the intention-to-treat analysis, the mean improvement in the WOMAC score after 6 months was 20.9 points (95% confidence interval [CI], 17.9 to 23.9) in the surgical group and 18.5 (95% CI, 15.6 to 21.5) in the physical-therapy group (mean difference, 2.4 points; 95% CI, -1.8 to 6.5). At 6 months, 51 active participants in the study who were assigned to physical therapy alone (30%) had undergone surgery, and 9 patients assigned to surgery (6%) had not undergone surgery. The results at 12 months were similar to those at 6 months. The frequency of adverse events did not differ significantly between the groups. In the intention-to-treat analysis, we did not find significant differences between the study groups in functional improvement 6 months after randomization; however, 30% of the patients who were assigned to physical therapy alone underwent surgery within 6 months.

To identify differences in applanation tonometry between retreated and nonretreated eyes (primary LASIK eyes) 6 months after hyperopic laser in situ keratomileusis. In a prospective study 100 eyes (100 patients) underwent conventional hyperopic laser in situ keratomileusis under a 160-microm flap. Central Goldmann applanation tonometry was determined before and 6 months after surgery in 78 (78%) primary LASIK eyes and before surgery and 6 months after the retreatment date in 22 (22%) retreated eyes. Preoperative mean tonometry was 14.96 +/- 1.96 mm Hg and 15.30 +/- 1.95 mm Hg in primary LASIK and retreated eyes, respectively. Six months after surgery it was 12.99 +/- 2.03 mm Hg (P < 0.001) and 12.67 +/- 2.20 mm Hg (P < 0.001), respectively. No significant differences in mean tonometry were found between retreated and primary LASIK eyes 6 months after surgery (P = 0.537). Decreased tonometric values were found in 20 retreated eyes (90.91%) and in 62 primary LASIK eyes (79.48%). Increased tonometric values higher than 1 mm Hg were found in 3 primary LASIK eyes (3.84%), but no retreated eyes showed increased values 6 months after surgery. Two retreated eyes (9.09%) and 10 primary LASIK eyes (79.49%) presented the same tonometric values before surgery and at the end of the study. After hyperopic laser in situ keratomileusis there was no significant difference in Goldmann applanation tonometry between retreated and primary LASIK eyes.

We assess the effect of CHARM, a gender equity and family planning counseling intervention for husbands in rural India, on men's gender ideology. We used a two-armed cluster randomized control trial design and collected survey data from husbands (n=1081) at baseline, 9 months, and 18 months. We used a continuous measure of support for gender equity and a dichotomous measure of equitable attitudes toward women's role in household decision-making. To assess differences on these outcomes, we used generalized linear mixed models. After controlling for socio-demographic factors, men who received the CHARM intervention were significantly more likely than men in the control group to have equitable attitudes toward household decision-making at 9-months follow-up; there was a non-significant difference between the groups for the measure of support for gender equity. For household decision-making, differences were not sustained at 18-months follow-up. Given the role of husbands' gender ideology in women's contraceptive use, the CHARM intervention represents a promising approach for challenging root causes of women's unmet need for contraception. © 2018 The Population Council, Inc.

Broiler chicken litter was kept as a stacked heap on a poultry farm, and samples were collected up to 9 months of storage. Chicken litter inoculated with desiccation-adapted Salmonella cells was heat-treated at 75, 80, 85, and 150°C. Salmonella populations decreased in all these samples during heat treatment, and the inactivation rates became lower in chicken litter when storage time was extended from 0 to 6 months. There was no significant difference (P > 0.05) in thermal resistance of Salmonella in 6- and 9-month litter samples, indicating that a threshold for thermal resistance was reached after 6 months. Overall, the thermal resistance of Salmonella in chicken litter was affected by the storage time of the litter. The changes in some chemical, physical, and microbiological properties during storage could possibly contribute to this difference. Moisture and ammonia could be two of the most significant factors influencing the thermal resistance of Salmonella cells in chicken litter. Our results emphasize the importance of adjusting time and temperature conditions for heat processing chicken litter when it is removed from the chicken house at different time intervals.

Overall, the thermal resistance of Salmonella in chicken litter was affected by the storage time of the litter. The changes in some chemical, physical, and microbiological properties during storage could possibly contribute to this difference. Moisture and ammonia could be two of the most significant factors influencing the thermal resistance of Salmonella cells in chicken litter. Our results emphasize the importance of adjusting time and temperature conditions for heat processing chicken litter when it is removed from the chicken house at different time intervals.

Brief Internet interventions have been shown to reduce alcohol consumption. This trial intended to compare the effects of one such brief intervention to an extended Internet intervention for problem drinkers. Using online advertising, 490 participants, 18 years or older, were recruited and randomized to receive a brief ( CheckYourDrinking.net ) versus an extended ( AlcoholHelpCentre.net ) Internet intervention and were followed up at 6, 12, and 24 months. The per protocol primary analysis assessed difference between condition at the 12-month follow-up. The follow-up rate at 12 months was 83.3 %. ANCOVAs of the primary (Alcohol Use Disorder Identification Test (AUDIT)-C) and secondary outcome variables (drinks in a typical week, highest number of drinks on one occasion-baseline drinking as covariate) revealed no significant (p > 0.05) differences between the interventions. Similarly, combined analyses of the 6-, 12-, and 24-month follow-up revealed no significant differences between interventions at all time points. The present study does not provide support for the added benefit of an extended Internet intervention for problem drinkers over a brief Internet intervention.

Three different samples of white chocolate were prepared: a sample with a synthetic antioxidant, another with casein peptides as natural antioxidant, and a third sample without any kind of antioxidant. Parameters associated with lipid oxidation and non-enzymatic browning were evaluated in the different samples of white chocolate during 10 months storage at 20 and 28°C. Acidity, thiobarbituric acid reactive substances and peroxide values increased with the incubation time. Samples stored at 20°C often showed lower values for these parameters than those stored at 28°C, although the differences were not always significant. The values for water activity increased from 0.4 to 0.53-0.57 during the period of 10 months. The color parameter a* was increased in samples stored at 28°C from month 5, and the parameter b* was lower in samples containing antioxidants from month 2. The addition of antioxidants did not significantly influence most the parameters studied, suggesting that the main parameters governing the alterations of white chocolate during its shelf-life was the storage temperature and increase in water activity.

Cluster randomised controlled trial. Clusters of adolescents (classrooms of 15- to 16-year-olds) in each school were allocated either into a control group or into an intervention group. The interventions consisted of peer cooperation (peer support) and peer interactive learning (observational learning) facilitated through feedback from a dentist (professional support). Three intervention sessions with preselected pairs of adolescents were delivered in the first three weeks. Gender, family socio-economic status (baseline) and different social-cognitive domain variables (baseline, six, and 12 months) were assessed using a questionnaire. Dental plaque levels were the primary outcome measure and they were measured at baseline, after the intervention measured only in the social-cognitive theory-guided group, at six and 12 months. At the six-month follow-up there was a statistically significant difference in means ± SD between the social-cognitive intervention group (27.4 ± 19.4) and the control group (35.1 ± 20.0). At the 12-month follow-up, there was no statistically significant difference in means ± SD between the social-cognitive intervention group (27.4 ± 18.5) and the control group (31.9 ± 17.8). Variations in dental plaque levels at different time periods were explained by the following predictors: family's socio-economic status, social-cognitive domain variables, group affiliation and baseline plaque levels. Social-cognitive theory-guided interventions improved oral self-care of adolescents in the short term. This improvement lasted only for five months after the intervention was discontinued.

Cardiac rehabilitation (CR) is a structured program for the prevention of secondary cardiovascular disease (CVD) and related diseases, such as hypertension, diabetes, and obesity. This study aimed to investigate whether there are gender differences after 9 months of home-based cardiac rehabilitation program in post-percutaneous coronary intervention patients. A total of 114 (58.29 ± 10.33 years) men and 30 (60.90 ± 9.32 years) women were enrolled in the CR program. The program included three visits: initial, 4th month (follow-up), and 9th month (final) visits at a CR center. The CR program included exercise and nutrition counseling. In nutrition counseling, a professional nutritionist educated the patients on how to organize the menu, incorporating an optimal caloric, low-salt, and low-cholesterol diet. Exercise was performed 30 min per session for more than 3 days per week with a target heart rate within 40-75% of the peak heart rate-resting heart rate (VO 2 reserve; VO 2 R) during intense exercise, which was based on ECG treadmill test. After 9 months, there was no significant difference in terms of dropout rate between men and women (p < 0.05). No significant changes were found in the anthropometric and lipid profiles in women, whereas the HDL-cholesterol (HDL-C) was significantly increased to 6.8% (p = 0.005) in men. The findings of our study showed that there was no difference in the CR participation rate between men and women. Moreover, there was an increase in HDL-C levels and an improvement in cardiorespiratory endurance, strength, and agility in men, whereas no significant difference in most risk factors and fitness variables was found in women. Thus, the 9-month home-based CR program was more effective for fitness in men, but only the HDL-C showed positive improvement among the cardiovascular risk factors. In women, 6-min walk and timed up and go were effective exercises.

Objective: To evaluate the effect of pharyngeal musculature and genioglossus exercising on obstructive sleep apnea and hypopnea syndrome (OSAHS). Methods: We conducted a non-randomized retrospective clinical trial of 75 patients with OSAHS. Fifty-four patients were managed by exercising of the pharyngeal musculature and genioglossus (exercising group). Twenty-one patients, who refused to undertake any treatment, were defined as the control group. We took the Epworth Sleepiness Scale (ESS), checked patients’ polysomnography, and took 320 detector computed tomography (CT) before treatment. Six and twelve months later, we made records of apnea hypopnea index (AHI), lowest arterial oxygen saturation (LSaO2), body mass index (BMI), the shortest sagittal diameter, and transverse diameter, and the effective rates of exercising were calculated and compared with the 21 patients without any treatment (control group) at the same time. SPSS 10.0 was used to analyze the data. Results: Before treatment, the ESS value was 7.67; 6 and 12 months later, the values were 3.54 and 3.25, respectively in the exercising group. AHI was decreased to 15.36 after 6 months and 13.79 after 12 months from 22.84 at the beginning. LSaO2 values were up to 81.18% after 6 months and 81.93% after 12 months from 74.05% at the beginning. There were significant differences in ESS scores, AHI, and LSaO2 between pre-treatment and post-treatment in the exercising group (P<0.05). However, there was no statistical difference in all the parameters between 6 and 12 months of exercising. The effective rates were 70.37% and 74.07% after 6- and 12-month exercising, respectively. There were significant differences between the exercising and control groups (P<0.0001). There was no statistical difference in the effective rate of the exercising group between 6 and 12 months of exercising (P>0.05). At 12 months of exercising, the compliance of the anteroposterior pharyngeal wall of the retropalatal area was lower (P<0.01) than that before treatment. There was no significant change of BMI in either group. Conclusions: Exercising pharyngeal musculature and genioglossus is a kind of non-invasive and cost-effective method to treat some OSAHS patients, especially those who are old, without surgical complications, and especially mild and moderate OSAHS patients who do not want to take surgery and continuous positive airway pressure (CPAP) treatment. In addition, exercising pharyngeal musculature and genioglossus can be considered as remedial treatment of OSAHS to surgery and other therapies. PMID:26537211

Objectives This study examined whether self-efficacy mediated the effect of the HIP Rehab exercise program on activity limitations in older adults after hip fracture, and whether the mediation effect was different between different gender and age groups. Design Randomized controlled trial (RCT) Setting Community Participants Two hundred and thirty two participants aged 79±9.4 years with hip fracture were randomly assigned to intervention (n=120) or attention control (n=112) groups. Interventions The 6-month intervention, the HIP Rehab, is a functionally-oriented, home-based exercise program. Data was collected at baseline, post-intervention (6 months), and follow-up (9 months). Main outcome measure Activity Measure for Post-Acute Care (AM-PAC) Results The mediation effect of the HIP Rehab exercise program on Basic Mobility function through self-efficacy for exercise was significant at 9 months (βindirect=0.21). Similarly, the mediation effect of the intervention on Daily Activity function through self-efficacy for exercise was significant at 9 months (βindirect=0.49). In subgroup analyses, the mediation effect was significant at 9 months in the younger group (≤79 years old) in comparison to the older group, and was significant in females in comparison to males. Conclusion Self-efficacy may play a partial mediating role for the effect on some longer-term functional outcomes in the HIP Rehab intervention. The results suggest that program components that target self-efficacy should be incorporated in the future hip fracture rehabilitation interventions. Age and gender of the targeted participants may also need to be considered when developing interventions. PMID:25701101

Scars on exposed areas are a major concern among Asian populations because of their conspicuousness. Size, color, or whether the scar is hypopigmented or hyperpigmented matters little. Silicone gel is well known for the prevention and induction of better maturation of hypertrophic and keloid scars. However, its aesthetic effect on normal surgical scars has not been considered. Clinical evaluation of scars was performed in 40 patients. All the 40 patients underwent clean and minor surgery of the exposed area, such as scar revision, by 1 plastic surgeon. Twenty of the 40 patients did not apply any adjunctive material for scar management and were grouped as the control. The other 20 patients applied a silicone gel sheet for 12 hours a day for 3 months. Three assessment criteria, pigmentation, vascularity, and height, were evaluated by photographic assessment of the scars at 2 weeks, 1 month, and 3 months postoperatively and scored by 3 plastic surgeons. The Wilcoxon rank sum test was used to verify any significant differences in the previously mentioned 3 parameters between the 2 groups and parameter scores at each follow-up period. Two patients were excluded from the study because of the development of rashes on the areas covered by the silicone gel sheet. There was no statistical significance between the groups at postoperative 2 weeks and 1 month in pigmentation and redness. For evaluation of height, there was statistical significance (P = 0.024) at postoperative 1 month. However, there were statistically significant differences in all the assessment criteria at postoperative 3 months between the groups: pigmentation, P = 0.0002; vascularity, P = 0.0002; and height, P < 0.0001. The silicone gel sheet has a favorable aesthetical effect for normally created surgical scars in the Asians. Its application can reduce the conspicuousness of scars more rapidly than without.

The aim of this article is to study the effect of unilateral congenital cataract surgery on ocular growth and corneal flattening. This is a cross-sectional study of 59 patients operated on due to a unilateral congenital cataract. The median age of the patients at the time of diagnosis was 17 months (interquartile range, 5-39 months). The median age at cataract the time of surgery was 28 months (interquartile range, 8-52 months), and the mean follow-up between cataract surgery and assessments was 149.7±69.9 months (range, 30-319 months). Axial length and corneal curvature were measured in both operated and non-operated eyes, comparing the results between them. There were no statistically significant differences for axial length growth or corneal flattening between operated and non-operated eyes: axial length (P=.327, Student t test) and corneal curvature (P=.078, Student t test). A sub-analysis was performed using the visual acuity and the age of the patient at the time of surgery. The only statistically significant data (P=.007, Student t test) was a lower axial length in operated eyes compared to non-operated eyes, in the non-deep-amblyopia group. No significant axial length growth modifications were observed between operated and non-operated eyes. Only the non-deep-amblyopia group presented with a lower axial length in the operated eyes compared to non-operated eyes. No significant differences in corneal flattening were found between groups after unilateral congenital cataract surgery. Copyright © 2011 Sociedad Española de Oftalmología.

A recent randomized trial (NCT01535209) demonstrated no difference in neurocognitive function between stereotactic radiotherapy of the tumor bed (SRT-TB) and whole brain radiotherapy (WBRT) in patients with resected single brain metastasis. Patients treated with SRT-TB had lower overall survival compared with the WBRT arm. Here, we compared the health-related quality of life (HRQOL) in patients who received WBRT vs. SRT-TB. A self-reported questionnaire was used to assess HRQOL (EORTC QLQ-C30 with the QLQ-BN20 module) before RT, 2 months after RT, and every 3 months thereafter. HRQOL results are presented as mean scores and compared between groups. Of 59 randomized patients, 37 (64%) were eligible for HRQOL analysis, 15 received SRT-TB, and 22 had WBRT. There were no differences between groups in global health status and main function scales/symptoms (except for drowsiness and appetite loss, which were worse with WBRT 2 months after RT). Global health status decreased 2 and 5 months after RT, but significantly only for SRT-TB (p = 0.025). Physical function decreased significantly 5 months after SRT-TB (p = 0.008). Future uncertainty worsened after RT, but significantly only for SRT-TB after 2 months (p = 0.036). Patients treated with WBRT had significant worsening of appetite, hair loss, and drowsiness after treatment. Despite higher symptom burden after WBRT attributed to the side effects of RT (such as appetite loss, drowsiness, and hair loss), global health status, physical functioning, and future uncertainty favored WBRT compared with SRT-TB. This may be related to the compromised brain tumor control with omission of WBRT.

Postoperative breathing exercises are recommended to cardiac surgery patients. Instructions concerning how long patients should continue exercises after discharge vary, and the significance of treatment needs to be determined. Our aim was to assess the effects of home-based deep breathing exercises performed with a positive expiratory pressure device for 2 months following cardiac surgery. The study design was a prospective, single-blinded, parallel-group, randomized trial. Patients performing breathing exercises 2 months after cardiac surgery (n = 159) were compared with a control group (n = 154) performing no breathing exercises after discharge. The intervention consisted of 30 slow deep breaths performed with a positive expiratory pressure device (10-15 cm H2O), 5 times a day, during the first 2 months after surgery. The outcomes were lung function measurements, oxygen saturation, thoracic excursion mobility, subjective perception of breathing and pain, patient-perceived quality of recovery (40-Item Quality of Recovery score), health-related quality of life (36-Item Short Form Health Survey), and self-reported respiratory tract infection/pneumonia and antibiotic treatment. Two months postoperatively, the patients had significantly reduced lung function, with a mean decrease in forced expiratory volume in 1 second to 93 ± 12% (P< .001) of preoperative values. Oxygenation had returned to preoperative values, and 5 of 8 aspects in the 36-Item Short Form Health Survey were improved compared with preoperative values (P< .01). There were no significant differences between the groups in any of the measured outcomes. No significant differences in lung function, subjective perceptions, or quality of life were found between patients performing home-based deep breathing exercises and control patients 2 months after cardiac surgery.

To investigate whether postoperative GnRH agonist (GnRH-a) treatment can prevent endometriosis recurrence. This meta-analysis searched PubMed, Embase and Cochrane Library for relevant studies published online before June 2015. Seven randomized controlled trials including 328 patients with postoperative GnRH-a treatment and 394 patients in control group were included in the meta-analysis. In the meta-analysis, the recurrence rate of GnRH-a group compared with control group was evaluated with odds ratio (OR) and its 95 % confidence interval (CI). Heterogeneity, small study effect and publication bias were, respectively, assessed using Higgins I (2), sensitivity analysis and funnel plot. Postoperative GnRH-a treatment for endometriosis (pooled OR = 0.71; 95 % CI 0.52-0.96) was superior to expectant or placebo treatment in prevention of the recurrence. The recurrence rate decreased significantly in patients who received 6 months GnRH-a treatment (pooled OR = 0.59, 95 % CI 0.38-0.90), whereas no significant difference of recurrence rate existed between patients with 3 months post-surgical GnRH-a therapy and the control group (pooled OR = 0.87, 95 % CI 0.56-1.34). No significant heterogeneity and small study effect were found in the meta-analysis. However, publication bias did existed in the present meta-analysis. Longer-term (6 months) postoperative administration of GnRH-a can decrease the recurrence risk of endometriosis, whereas 3 months duration of GnRH-a therapy makes no significant difference in preventing the recurrence of endometriosis. Therefore, instead of a 3 month therapy, the duration of the postoperative administration should be longer enough (6 months) to prevent the recurrence of endometriosis.

To examine effects of physical and geriatric rehabilitation on institutionalisation and mortality after hip fracture. Prospective randomised study. Physically oriented (187 patients), geriatrically oriented (171 patients), and health centre hospital rehabilitation (180 patients, control group). A total of 538 consecutively, independently living patients with non-pathological hip fracture. Patients were evaluated on admission, at 4 and 12 months for social status, residential status, walking ability, use of walking aids, pain in the hip, activities of daily living (ADL) and mortality. Mortality was significantly lower at 4 and 12 months in physical rehabilitation (3.2%, 8.6%) than in geriatric rehabilitation group (9.6%, 18.7%, P=0.026, P=0.005, respectively) or control group (10.6%, 19.4%, P=0.006, P=0.004, respectively). At 4 months more patients in physical (84.4%) and geriatric rehabilitation group (78.0%) were able to live at home or sheltered housing than in control group (71.9%, P=0.0012 and P<0.001, respectively). No significant difference was found between physical rehabilitation and geriatric rehabilitation (P=0.278). Analysis of femoral neck and trochanteric fractures showed that significant difference was true only for femoral neck fractures (physical rehabilitation vs geriatric rehabilitation P=0.308, physical rehabilitation vs control group P<0,001 and geriatric rehabilitation vs control group P<0.001). Effects of intensified rehabilitations disappeared at 12 months. No impact on walking ability or ADL functions was observed. Physical rehabilitation reduced mortality. Physical and geriatric rehabilitation significantly improved the ability of independent living after 4 months especially among the femoral neck fracture patients but this effect could not be seen after 12 months. © The Author(s) 2014.

To compare cognitive function in postmenopausal women receiving continuous hormone replacement therapy and those receiving tibolone. This was a 6-month, prospective, single-blind, single center, randomized study. A total of 50 healthy, postmenopausal women were enrolled. In the end, 40 women completed the 6-month follow-up. One group (23 subjects) received conjugated equine estrogens (CEE), 0.625 mg/d, and medroxyprogesterone acetate (MPA), 5 mg/d. The other group (17 subjects) received tibolone, 2.5 mg/d. Their serum estradiol levels and Cognitive Abilities Screening Instrument (CASI) and Mini-Mental State Examination (MMSE) scores were obtained before starting and after 3 and 6 months of treatment. There was a significant increase in the serum estradiol level in the CEE + MPA group, especially after 3 months of treatment, but there was no increase in the estradiol level in the tibolone group. The CASI and MMSE scores of the CEE + MPA group and the tibolone group after 3 and 6 months of treatment showed no significant difference between the two groups apart from the MMSE at the 3-month follow-up. We saw an increasing trend in CASI and MMSE scores after treatment in both groups; however, the increases were not statistically significant. The rate of increase of both CASI and MMSE scores in the CEE + MPA group was greater than in the tibolone group, though the difference was not significant. This preliminary study demonstrated that both CEE + MPA and tibolone can preserve cognitive function and may be able to prevent cognitive decline in postmenopausal women during short-term treatment. Our results also show that continuous, combined CEE + MPA seems to be marginally more effective than tibolone in improving cognitive processes; however, long-term study is needed to follow-up such effect.

Nasal obstruction is known to cause resistance to continuous positive airway pressure (CPAP) therapy in obstructive sleep apnea syndrome (OSAS). In this paper, short- and long-term nasal congestion in OSAS patients receiving CPAP treatment were evaluated with acoustic rhinometry (AR). A total of 36 patients with moderate-to-severe OSAS, diagnosed with polysomnography were included in the study. Ten healthy subjects without OSAS constituted the control group. Pre-treatment nasal patency were measured with AR in all participants. 26 patients used the recommended CPAP treatment. Ten patients did not accept CPAP treatment. The AR test was repeated for all the subjects after 1 and 3 months except the 3rd month's measurements of the control group. There was no statistically significant difference between the initial minimum cross-sectional area (MCA) measurements of OSAS patients, using or not using CPAP, and the control group (P > 0.05). However, the first month MCA measurements of patients receiving CPAP were found to be significantly decreased compared with the initial values (P < 0.001). There was no significant change in the first and third months MCA values in the control group and patients who did not use CPAP (P > 0.05). No significant difference revealed in the 3rd month MCA measurements of the patients using CPAP compared with the initial values (P > 0.05). In this study, the increased nasal congestion, which is thought to be the cause of CPAP resistance, was objectively demonstrated in OSAS patients using CPAP. In addition, the nasal congestion developing at the first month was shown to disappear over time, supporting the opinion that patient compliance in CPAP treatment is expected to increase after regular device usage.

A recent phase III trial compared the efficacy of cisplatin-topotecan (a topoisomerase I inhibitor) followed by carboplatin-paclitaxel (Arm 1) versus paclitaxel-carboplatin (Arm 2) in women with newly diagnosed stage IIB or greater ovarian cancer. There was a significantly lower response rate in the experimental arm compared to standard treatment, and less likelihood of normalized CA125 within the first 3 months. At 43 months follow-up, there were no significant group differences in progression-free survival. There were also significantly more side effects in the experimental arm. The current study examined quality of life (QoL) endpoints using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) and the ovarian cancer module, QLQ-OV28, administered prior to randomization, at day 1 of treatment cycles 3, 5, and 7, at completion of the last cycle, and at 3 and 6 months following completion of chemotherapy. Global QoL, physical symptoms, fatigue, and role, emotional, cognitive and social function (all from the EORTC QLQ-C30) significantly improved in both treatment arms, with no significant between-arm differences. Between-group differences in pain, insomnia, and peripheral neuropathy reported while on treatment did not differ at follow-up. Nausea and vomiting improved more with standard treatment both during and after treatment. Body image significantly differed between the groups only at cycle 5 (more deterioration in Arm 2) but group differences disappeared at follow-up. A stratified analysis of global QoL by debulking surgery status found no greater effect indicating that overall improvements in QoL were unrelated to surgical recovery. There was no significant QoL advantage of cisplatin-topotecan. This finding, combined with no progression-free survival conferred by this combination, reaffirms carboplatin-paclitaxel as the standard of care for women with newly diagnosed ovarian cancer.

Moss nitrogen (N) concentrations and natural 15 N abundance (δ 15 N values) have been widely employed to evaluate annual levels and major sources of atmospheric N deposition. However, different moss species and one-off sampling were often used among extant studies, it remains unclear whether moss N parameters differ with species and different samplings, which prevented more accurate assessment of N deposition via moss survey. Here concentrations, isotopic ratios of bulk carbon (C) and bulk N in natural epilithic mosses (Bryum argenteum, Eurohypnum leptothallum, Haplocladium microphyllum and Hypnum plumaeforme) were measured monthly from August 2006 to August 2007 at Guiyang, SW China. The H. plumaeforme had significantly (P < 0.05) lower bulk N concentrations and higher δ 13 C values than other species. Moss N concentrations were significantly (P < 0.05) lower in warmer months than in cooler months, while moss δ 13 C values exhibited an opposite pattern. The variance component analyses showed that different species contributed more variations of moss N concentrations and δ 13 C values than different samplings. Differently, δ 15 N values did not differ significantly between moss species, and its variance mainly reflected variations of assimilated N sources, with ammonium as the dominant contributor. These results unambiguously reveal the influence of inter-species and intra-annual variations of moss N utilization on N deposition assessment. Copyright © 2017 Elsevier Ltd. All rights reserved.

Abstract Objective To assess the effectiveness of a school and family based healthy lifestyle programme (WAVES intervention) compared with usual practice, in preventing childhood obesity. Design Cluster randomised controlled trial. Setting UK primary schools from the West Midlands. Participants 200 schools were randomly selected from all state run primary schools within 35 miles of the study centre (n=980), oversampling those with high minority ethnic populations. These schools were randomly ordered and sequentially invited to participate. 144 eligible schools were approached to achieve the target recruitment of 54 schools. After baseline measurements 1467 year 1 pupils aged 5 and 6 years (control: 28 schools, 778 pupils) were randomised, using a blocked balancing algorithm. 53 schools remained in the trial and data on 1287 (87.7%) and 1169 (79.7%) pupils were available at first follow-up (15 month) and second follow-up (30 month), respectively. Interventions The 12 month intervention encouraged healthy eating and physical activity, including a daily additional 30 minute school time physical activity opportunity, a six week interactive skill based programme in conjunction with Aston Villa football club, signposting of local family physical activity opportunities through mail-outs every six months, and termly school led family workshops on healthy cooking skills. Main outcome measures The protocol defined primary outcomes, assessed blind to allocation, were between arm difference in body mass index (BMI) z score at 15 and 30 months. Secondary outcomes were further anthropometric, dietary, physical activity, and psychological measurements, and difference in BMI z score at 39 months in a subset. Results Data for primary outcome analyses were: baseline, 54 schools: 1392 pupils (732 controls); first follow-up (15 months post-baseline), 53 schools: 1249 pupils (675 controls); second follow-up (30 months post-baseline), 53 schools: 1145 pupils (621 controls). The mean BMI z score was non-significantly lower in the intervention arm compared with the control arm at 15 months (mean difference −0.075 (95% confidence interval −0.183 to 0.033, P=0.18) in the baseline adjusted models. At 30 months the mean difference was −0.027 (−0.137 to 0.083, P=0.63). There was no statistically significant difference between groups for other anthropometric, dietary, physical activity, or psychological measurements (including assessment of harm). Conclusions The primary analyses suggest that this experiential focused intervention had no statistically significant effect on BMI z score or on preventing childhood obesity. Schools are unlikely to impact on the childhood obesity epidemic by incorporating such interventions without wider support across multiple sectors and environments.

Coercive and prosocial fathering, antisocial personality, and growth in children's postdivorce noncompliance.

PubMed

DeGarmo, David Scott

2010-01-01

To better understand quantity and quality of divorced father contact, a weighted county sample of 230 divorced fathers with a child aged 4-11 years was employed to test whether fathers' antisocial personality (ASP) moderated effects of monthly contact with children in predicting children's observed noncompliance. Eighteen-month latent growth models obtained significant individual differences in levels of noncompliance and growth rates. ASP significantly moderated beneficial impact of fathers' monthly contact. Fathers' observed parenting practices significantly predicted noncompliance levels but not growth. Parenting did not account for the effect of Contact x ASP, suggesting both environmental and potentially genetic influences on child adjustment. Findings were robust across boys and girls and age levels. Implications for preventive intervention are discussed.

In the setting of a six-month, open-label clinical trial, 141 consecutively enrolled, hypertensive, overweight patients were randomized to the oral ingestion of psyllium powder or guar gum 3.5 gr t.i.d., to be taken 20 min before the main two meals, or to standard diet. Both fibers improved significantly BMI, FPG, FPI, HOMA Index, HbA1c, LDL-C, and ApoB. Psyllium supplementation only exerted a significant improvement in plasma TG concentration, in SBP and DBP. In our study, six-month supplementation with psyllium fiber, but not with guar fiber nor standard diet, appears to significantly reduce both SBP and DBP in hypertensive overweight subjects.

Patients who have a stroke are not always admitted to hospital, and 22-60% remain in the community, frequently without coordinated rehabilitation. We aimed to assess the efficacy of an occupational therapy intervention for patients with stroke who were not admitted to hospital. In this single-blind randomised controlled trial, consecutive stroke patients on a UK community register in Nottingham and Derbyshire were allocated randomly to up to 5 months of occupational therapy at home or to no intervention (control group) 1 month after their stroke. The aim of the occupational therapy was to encourage independence in personal and instrumental activities of daily living. Patients were assessed on outcome measures at baseline (before randomisation) and at 6 months. The primary outcome measure was the score on the extended activities of daily living (EADL) scale at 6 months. Other outcome measures included the Barthel index, the general health questionnaire 28, the carer strain index, and the London handicap scale. All assessments were done by an independent assessor who was unaware of treatment allocation. The analysis included only data from completed questionnaires. 185 patients were included: 94 in the occupational therapy group and 91 in the control group. 22 patients were not assessed at 6 months. At follow-up, patients who had occupational therapy had significantly higher median scores than the controls on: the EADL scale (16 vs 12, p<0.01, estimated difference 3 [95% CI 1 to 4]); the Barthel index (20 vs 18, p<0.01, difference 1, [0-1]); the carer strain index (1 vs 3, p<0.05, difference 1 [0 to 2]); and the London handicap scale (76 vs 65, p<0.05, difference 7, [0.3 to 13.5]). There were no significant differences on the general health questionnaire between the patient or carer. Occupational therapy significantly reduced disability and handicap in patients with stroke who were not admitted to hospital.

To study the sympathetic skin response (SSR) to the effects of N-hexane on autonomic nerves function in patients with chronic N-hexane poisoning. The subjects in present study included 30 controls and 37 cases with chronic N-hexane poisoning. Also 37 patients were divided into 3 subgroups (mild, moderate and severe poisoning) according to diagnostic criteria of occupational diseases. All subjects were examined by SSR test and nerve conduction velocity (NCV) test. All patients were reexamined by SSR and NCV every 1 ∼ 2 months. The differences in SSR parameters (latency, amplitude) among groups were observed. In the severe poisoning subgroup, the changes of SSR and NCV parameters (conduction velocity, amplitude) in different poisoning stages were observed. There were significant differences in SSR latency of upper extremity among groups and the significant differences in SSR amplitude of upper and lower extremity among groups (P < 0.05). No significant differences in SSR parameters were found between the adjacent groups (P > 0.05). There were significant differences in SSR latency of upper extremity during different periods and the significant differences in SSR amplitude of upper and lower extremity during different periods among all groups (P < 0.05). The change of SSR parameters consistent with that in NCV. The longest SSR latency of upper extremity and the smallest SSR amplitudes of upper and lower extremity appears 1 - 2 months earlier than that of the smallest action potential amplitude. The damage of autonomic nerves induced by N-hexane increased with poisoning progresses. The damage of autonomic nerves corresponded with the damage of myelin sheath of large myelinated nerves, but which appeared 1 - 2 months earlier than the damage of axon of large myelinated nerves. SSR test may serve as a method to detect the damage of autonomic nerves function in patients with chronic N-hexane poisoning.

A certain weight gain occurs after obesity surgery compared to the lower weight usually observed between 18 and 24 months postsurgery. The objective of this study was to evaluate weight regain in patients submitted to gastric bypass over a 5-year follow-up period. A longitudinal prospective study was conducted on 782 obese patients of both genders. Only patients with at least 2 years of surgery were included. The percentage of excess body mass index (BMI) loss at 24, 36, 48, and 60 months postsurgery was compared to the measurements obtained at 18 months after surgery. Surgical therapeutic failure was also evaluated. Percent excess BMI loss was significant up to 18 months postsurgery (p < 0.001), with a mean difference in BMI of 1.06 kg/m2 compared to 12 months postsurgery. Percent BMI loss was no longer significant after 24 months, and weight regain became significant within 48 months after surgery (p < 0.01). Among the patients who presented weight regain, a mean 8% increase was observed within 60 months compared to the lowest weight obtained at 18 months after surgery. The percentage of surgical failure was higher in the superobese group at all times studied, reaching 18.8% at 48 months after surgery. Weight regain was observed within 24 months after surgery in approximately 50% of patients. Both weight regain and surgical failure were higher in the superobese group. Studies in regard to metabolic and hormonal mechanisms underlying weight regain might elucidate the causes of this finding.

The aim of the study was to describe the evolution of the different dimensions of insight at 1 year and its associations with psychopathology and symptomatic remission. Participants included 55 patients hospitalized for a first psychosis episode and followed up at 6 and 12 months after discharge. Measures included the Scale to Assess Unawareness of Mental Disorder and the Positive and Negative Syndrome Scale (PANSS). Six dimensions of insight were evaluated, for current episode at hospital discharge and at 6 and 12 month FUs and past episode (at 6 and 12 month follow-ups). Our results show that concerning the current episode, only awareness of the social consequences and of the positive symptoms significantly improved during follow-up. Insight into the past episode improved for awareness of having a mental disorder, the social consequences and the positive symptoms of mental illness. Cross-sectional associations between insight and PANSS show weak to moderate, albeit significant, associations. Most of the dimensions of insight are positively and significantly associated with remission. Our findings suggest that the main underlying dimensions of insight evolve differently over time, which could suggest different inherent processes. This could be useful for developing psychotherapeutic programmes acting upon the different aspects of insight. © 2013 Elsevier Ireland Ltd. All rights reserved.

The purposes of this study were (1) determine if youth peak Achilles tendon (AT) strain, peak AT stress, and AT stiffness, measured during an isometric plantar flexion, differed after six months (mos) of growth, and (2) determine if sex, physical activity level (Physical Activity Questionnaire (PAQ-C)), and/or growth rate (GR) were related to these properties. AT stress, strain, and stiffness were quantified in 20 boys (13.47±0.81 years) and 22 girls (11.18±0.82 years) at 2 times (0 and 6 mos). GR (change in height in 6 mos) was not significantly different between boys and girls (3.5±1.4 and 3.4±1.1cm/6 mos respectively). Peak AT strain and stiffness (mean 3.8±0.4% and 128.9±153.6N/mm, respectively) did not differ between testing sessions or sex. Peak AT stress (22.1±2.4 and 24.0±2.1MPa at 0 and 6 mos, respectively) did not differ between sex and increased significantly at 6 mos due to a significant decrease in AT cross-sectional area (40.6±1.3 and 38.1±1.6mm(2) at 0 and 6 mos, respectively) with no significant difference in peak AT force (882.3±93.9 and 900.3± 65.5N at 0 and 6 mos, respectively). Peak AT stress was significantly greater in subjects with greater PAQ-C scores (9.1% increase with 1 unit increase in PAQ-C score) and smaller in subjects with faster GRs (13.8% decrease with 1cm/6 mos increase in GR). These results indicate that of the AT mechanical properties quantified, none differed between sex, and only peak AT stress significantly differed after 6 months and was related to GR and physical activity.

The purpose of this study was to evaluate the 12-month clinical performance of glass ionomer restorations in teeth with MIH. First permanent molars affected by MIH (48) were restored with glass ionomer cement (GIC) and evaluated at baseline, at 6 and at 12 months, by assessing tooth enamel breakdown, GIC breakdown and caries lesion associations. The data were analyzed using the chi-square test and actuarial survival analysis. The likelihood of a restored tooth remaining unchanged at the end of 12 months was 78%. No statistically significant difference was observed in the association between increased MIH severity and caries at baseline (p > 0.05) for a 6-month period, or between increased MIH severity and previous unsatisfactory treatment at baseline (p > 0.05) for both a 6- and 12-month period. A statistically significant difference was observed in the association between increased MIH severity and extension of the restoration, involving 2 or more surfaces (p < 0.05) at both periods, and between increased MIH severity and caries at baseline (p < 0.05) at a 12-month period. Because the likelihood of maintaining the tooth structures with GIC restorations is high, invasive treatment should be postponed until the child is sufficiently mature to cooperate with the treatment, mainly of teeth affected on just one face.

Background Immune thrombocytopenic purpura (ITP) is the most prevalent cause of thrombocytopenia in children. Despite the importance of ITP in children under 2-years old, only a few publications are available in the literature.ITP usually presents itself as isolated thrombocytopenia and mucocutaneous bleeding. Materials and Methods This study was conducted on 187 under 2-year-old children diagnosed with ITP and treated at Dr. Sheikh Hospital from 2004 to 2011.In this retrospective study, clinical symptoms, laboratory findings, history of viral infections, vaccination history, and treatment efficacy in children under 2-years old with ITP were investigated.Patients were followed for one year after being discharged from the hospital. Results The risk of the disease developing into chronic form was higher in older children (0.001). ITP in children under 3-months old was significantly associated with vaccination (p=0.007). There was no significant differences between male and female patients in regards to newly diagnosed ITP, persistent, and chronic disease status (p = 0.21). No significant difference in bleeding symptoms was observed between patients under 3-months old and 3 to 24-months old (p=0.18). Conclusion Infantile ITP respond favorably to treatment. The risk of the disease developing into chronic form is higher in 3-to-24-month-old children compared to under-three-month olds. PMID:27222699

A long-term study in adults at a public dental clinic in Sweden was initiated to evaluate the relative effectiveness of prophylactic treatments on the progression of dental caries and periodontal discase. With treatments scheduled every 3rd, 6th, 12th or 18th month, this report presents results on caries for the 3-month, 6-month and 18-month groups, and evaluates the impact of various caries-related risk factors. Caries increment over approximately 5 years was determined by adding clinical and radiographic findings of manifest primary and secondary caries during the study. Overall caries activity among all 105 participating individuals was low to moderate. No significant differences for caries on any of the various tooth surfaces or for total caries were observed among the three groups. Multiple regression analysis with 5-year caries increment as dependent variable showed that the following factors had a statistically significant association with caries increment: percentage filled surfaces at baseline examination, dietary score, plaque score, and number of mutans streptococci and lactobacilli in saliva. Non-significant factors included number of preventive treatments provided during the 5-year interval. The results of this long-term trial suggest that preventive treatments as often as every 3 6 months may not be justified in the case of patients with low to moderate caries activity.

Photothermal destruction of hair shaft melanin with intense pulsed light (IPL) and neodymium:yttrium-aluminum-garnet (Nd:YAG) laser has become an effective treatment of hair removal. Our aim was to compare efficacy, satisfactory levels, safety, and side effects of Nd:YAG and IPL in hair reduction. This was a prospective randomized intrapatient, right-left, assessor-blinded comparison of Nd:YAG vs IPL. There were 38 volunteers recruited. Seven sessions were performed. Hair count, efficacy, and side effects were compared before and after each treatment and 6 months after the last treatment. In respect of 12 volunteers, we have examined the reduction in hair after 18 months. Initially, there was no significant difference between the numbers of hair follicles. There was significant hair reduction after each treatment on the Nd:YAG-treated side. The hair reduction became significant after the third treatment with IPL. Comparison of the efficacy of the two devices on each visits showed no significant difference. There was statistically lower pain score on the IPL-treated side and statistically higher erythema, burning sensation, and edema on the Nd:YAG-treated side. Statistically lower side effect score was observed on the IPL-treated side. Eight months after the last treatment, there was significant hair reduction both on the Nd:YAG and on the IPL-treated side, and there was no difference between the efficacy. The patient satisfaction scores were higher with the IPL. Unwanted hair can be reduced by both systems safely and effectively; however, IPL has less side effects and higher satisfaction scores. © 2017 Wiley Periodicals, Inc.

Plasma luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin (PRL) and testosterone levels were measured in nine eugonadal men in New Delhi and during the 1st week of different months of their stay at Dakshin Gangotri in Antarctica. During their 12-month stay in Antarctica, they were exposed to a severely cold climate, long polar nights and polar days, high wind velocity, increased amounts of solar and ultraviolet radiation and geomagnetism, as well as physical and social isolation. Plasma testosterone tended to increase in March, but a significant increase (P < 0.05) was not seen until April. The mean testosterone levels in May, June, September and November were also significantly higher than the March or New Delhi values. The absolute values of LH, FSH and PRL did not show any month-to-month changes in Antarctica. However, when the hormone levels were expressed as a percentage of the individual annual Antarctic mean, significant differences as a percentage of the individual annual Antarctic mean, significant differences were observed. The testosterone peak in April, May and June was associated with an increase in LH. The nadirs of testosterone, LH, FSH and PRL were seen in either July or August. FSH showed the highest values in March, whereas the highest PRL values were seen in November. These observations suggest the presence of circannual variations in gonadotropin, PRL and LH in Antarctica which are independent of polar days and polar nights. It appears that factors other than the duration of daylight might be involved in regulating these changes. The significance of maintenance of testosterone levels in the supra-physiological range in Antarctica remains unknown but may be important in acclimatization/habituation to the extreme polar cold by increasing basal metabolic rate, protein synthesis and erythropoiesis.

Self-expandable metal stents (SEMSs) are used to relieve malignant biliary obstruction. To compare outcomes between covered self-expandable metal stents (CSEMSs) and uncovered self-expandable metal stents (USEMSs) in malignant biliary obstruction. Retrospective cohort study. Tertiary cancer center. Patients with malignant biliary obstruction. Placement of CSEMS or USEMS. Time to recurrent biliary obstruction (TRO), overall survival (OS), and adverse events. From January 2000 to June 2011, 749 patients received SEMSs: 171 CSEMSs and 578 USEMSs. At 1 year, there was no significant difference in the percentage of patients with recurrent obstruction (CSEMSs, 35% vs USEMSs, 38%) and survival (CSEMSs, 45% vs USEMSs, 49%). There was no significant difference in the median OS (CSEMSs, 10.4 months vs USEMSs, 11.8 months; P = .84) and the median TRO (CSEMSs, 15.4 months vs USEMSs, 26.3 months; P = .61). The adverse event rate was 27.5% for the CSEMS group and 27.7% for the USEMS group. Although tumor ingrowth with recurrent obstruction was more common in the USEMS group (76% vs 9%, P < .001), stent migration (36% vs 2%, P < .001) and acute pancreatitis (6% vs 1%, P < .001) were more common in the CSEMS group. Retrospective study. There was no significant difference in the patency rate or overall survival between CSEMSs and USEMSs for malignant distal biliary strictures. The CSEMS group had a significantly higher rate of migration and pancreatitis than the USEMS group. No significant SEMS-related adverse events were observed in patients undergoing neoadjuvant chemoradiation or surgical resection. Copyright © 2013 American Society for Gastrointestinal Endoscopy.

To assess the effect of SofZia-preserved travoprost on ocular surface conditions in comparison with benzalkonium chloride (BAK)-preserved latanoprost. A prospective randomized multicentre single-masked comparative study. Patients with open-angle glaucoma or ocular hypertension who had been treated with BAK-preserved latanoprost 0.005% (Xalatan(®) ) monotherapy for at least 3 months. Patients were enrolled at 23 facilities. Patients were randomly divided into the X-X group, continuous use of Xalatan(®) , or the X-T group, switching from Xalatan(®) to SofZia-preserved travoprost 0.004% (TravatanZ(®) ), and followed for 3 months. The superficial punctate keratopathy (SPK), conjunctival epitheliopathy, hyperaemia, tear break-up time (TBUT) and intraocular pressure (IOP) were examined for each patient in a masked manner. Changes in the frequency of keratoconjunctival epitheliopathy were evaluated 3 months after study initiation. Intra- and intergroup comparisons of changes in SPK, conjunctival epitheliopathy, hyperaemia, TBUT and IOP were also carried out. Two hundred twenty patients participated and 215 completed the 3-month study. The frequency of keratoconjunctival epitheliopathy significantly decreased in the X-T group (p = 0.036) and the intergroup difference was also significant (p = 0.001). SPK scores and TBUT were significantly improved in the X-T group (p = 0.034, 0.049), also with significant intergroup differences in the cornea excluding the inferior area and TBUT. There were no significant intergroup differences in changes of the hyperaemia scores and the IOP reduction. Switching to SofZia-preserved travoprost after BAK-preserved latanoprost resulted in a lower incidence of keratoconjunctival epitheliopathy, especially in the cornea, with no clinically relevant changes in hyperaemia and IOP. © 2012 The Authors.

Selenium supplementation may decrease circulating thyroid autoantibodies in patients with chronic autoimmune thyroiditis (AIT), but the available trials are heterogenous. This study expands and critically reappraises the knowledge on this topic. A literature search identified 3366 records. Controlled trials in adults (≥18 years of age) with AIT, comparing selenium with or without levothyroxine (LT4), versus placebo and/or LT4, were eligible. Assessed outcomes were serum thyroid peroxidase (TPOAb) and thyroglobulin (TgAb) autoantibody levels, and immunomodulatory effects. After screening and full-text assessment, 16 controlled trials were included in the systematic review. Random-effects meta-analyses in weighted mean difference (WMD) were performed for 3, 6, and 12 months of supplementation in two different populations: one receiving LT4 therapy and one newly diagnosed and LT4-untreated. Heterogeneity was estimated using I 2 , and quality of evidence was assessed per outcome, using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) guidelines. In LT4-treated populations, the selenium group had significantly lower TPOAb levels after three months (seven studies: WMD = -271 [confidence interval (CI) -366 to -175]; p < 0.0001; I 2  = 45.4%), which was consistent at six months (three studies) and 12 months (one study). TgAb decreased at 12 months, but not at three or six months. In LT4-untreated populations, the selenium group showed a decrease in TPOAb levels after three months (three studies: WMD = -512 [CI -626 to -398]; p < 0.0001, I 2  = 0.0%), but not after 6 or 12 months. TgAb decreased at 3 months, but not at 6 or 12 months. Quality of evidence was generally assessed as low. Study participants receiving selenium had a significantly higher risk than controls of reporting adverse effects (p = 0.036). Selenium supplementation reduced serum TPOAb levels after 3, 6, and 12 months in an LT4-treated AIT population, and after three months in an untreated AIT population. Whether these effects correlate with clinically relevant measures remains to be demonstrated.

To evaluate clinically and radiographically an alveolar ridge, preservation technique with deproteinized bovine bone graft and absorbable collagen membrane and then restoration with delayed implants were done. The study included 30 patients. The trial group's sockets were filled with deproteinized bovine bone graft (Bio-Oss) and covered with absorbable collagen membrane (Bio-Gide). The control group's sockets healed without any treatment. Panoramic radiograph and computed tomography were taken immediately after graft and 3 and 6 months later to evaluate the height, width, and volume change of the alveolar ridge bone. Dental implants were inserted in all sockets at 6 months, and osseointegration condition was evaluated in the following 12 months. All sockets healed uneventfully. In the trial group, the mean (SD) height reduction of the alveolar ridge bone was 1.05 (0.24) mm at 3 months and 1.54 (0.25) mm at 6 months. The width reduction was 1.11 (0.13) mm at 3 months and 1.84 (0.35) mm at 6 months. Bone volume reduction was 193.79 (21.47) mm at 3 months and 262.06 (33.08) mm at 6 months. At the same trend, in the control group, the bone height reduction was 2.12 (0.15) mm at 3 months and 3.26 (0.29) mm at 6 months. The width reduction was 2.72 (0.19) mm at 3 months and 3.56 (0.28) mm at 6 months. Bone volume reduction was 252.19 (37.21) mm at 3 months and 342.32 (36.41) mm at 6 months. There was a significant difference in alveolar ridge bone height, width, and volume reduction in the 2 groups. The osseointegration condition had no significant difference between the 2 groups. This study suggested that the deproteinized bovine bone graft and absorbable collagen membrane were beneficial to preserve the alveolar ridge bone and had no influence on the osseointegration of delayed implant.

Abstract Background To analyze protective/regenerative effects of adipose tissue-derived mesenchymal stem cells (ADMSC) on 131I-Radioiodine (RAI)-induced salivary gland damage in rats. Materials and Methods Study population consisted of controls (n:6) and study groups (n:54): RAI (Group 1), ADMSC (Group 2), amifostine (Group 3), RAI+amifostine (Group 4), concomitant RAI+ADMSC (Group 5) and RAI+ADMSC after 48 h (Group 6). We used light microscopy (LM), transmission electron microscopy (TEM), and salivary gland scintigraphy (SGS), and analyzed data statistically. Results We observed the homing of ADMSC in salivary glands at 1st month on LM. RAI exposure affected necrosis, periductal fibrosis, periductal sclerosis, vascular sclerosis and the total sum score were in a statistically significant manner (P < 0.05). Intragroup comparisons with LM at 1st and 6th months revealed statistically significant improvements in Group 6 (P < 0.05) but not in Groups 4 and 5. Intergroup comparisons of the total score showed that Groups 4 and 5 in 1st month and Group 6 in 6th month had the lowest values. TEM showed vacuolization, edema, and fibrosis at 1st month, and an improvement in damage in 6th month in Groups 5 and 6. SGSs revealed significant differences for the maximum secretion ratio (Smax) (P = 0.01) and the gland-to-background ratio at a maximum count (G/BGmax) (P = 0. 01) at 1st month, for G/BGmax (P = 0.01), Smax (P = 0.01) and the time to reach the maximum count ratio over the time to reach the minimum count (Tmax/Tmin) (P = 0.03) at 6th month. 1st and 6th month scans showed differences for Smax and G/BGmax (P = 0.04), but not for Tmax/Tmin (p > 0.05). We observed a significant deterioration in gland function in group 1, whereas, mild to moderate deteriorations were seen in protective treatment groups. Conclusions Our results indicated that ADMSC might play a promising role as a protective/regenerative agent against RAI-induced salivary gland dysfunction. PMID:28959167

Declining cognitive function is relatively common and increasingly prevalent. Studies have shown that different nutrients (e.g., Ginkgo biloba and vitamin E) appear to be effective at improving memory and concentration, while less is known about their effect on immunity. This study investigated the effect of Ginkgo Synergy(®) plus Choline (n = 33) and OPC Synergy(®) plus Catalyn(®) (n = 31) versus placebo (n = 33) in a 6-month, randomized, double-blind trial on cognitive and immune functioning among English-speaking, non-smoking, healthy older adults. The Stroop Color and Word Test, Trail Making Test A and B, Controlled Oral Word Association, Hopkins Verbal Learning, Mini-Mental State Exam, and Digit Symbol were administered at baseline and 3 and 6 months follow-up to assess cognitive functioning. Cytokines and growth factors were measured at baseline and 6 months to assess inflammation and immune functioning. Data were analyzed with linear mixed modeling. No serious adverse events were noted in this study. According to time on the Trail Making Test-B, the Ginkgo Synergy(®) plus Choline arm showed improvement from baseline to 3 months follow-up (mean difference = 24.2; SE = 6.4; 95% CI: 8.6, 39.7; p = 0.01). On the Controlled Oral Word Association Trial-S, the scores significantly increased for the Ginkgo Synergy(®) plus Choline arm from baseline to 6 months follow-up (mean difference = 2.1; SE = 0.8; 95% CI: 0.2, 3.9; p < 0.05) and for the OPC Synergy(®) plus Catalyn(®) arm from baseline to 3 months follow-up (mean difference = 2.1; SE = 0.8; 95% CI: 0.2, 4.0; p < 0.05). Epidermal growth factor significantly decreased from baseline to 6 months follow-up for the Ginkgo Synergy(®) plus Choline arm (mean difference = 120.7; SE = 28.4; 95% CI: 62.6, 178.8; p < 0.001). Our study showed isolated and modest effects of a Ginkgo biloba plus choline-based formula on cognitive and immune functioning among healthy older adults with no history of significant cognitive deficits. Our trial was registered with clinicaltrials.gov (ID: NCT01672359). This study was supported by a grant from Standard Process, Inc.

Many patients with an inguinal hernia are asymptomatic or have little in the way of symptoms from their hernia. Repair is often associated with long-term chronic pain and has a recurrence rate of 5% to 10%. Our aim was to compare operation with a wait-and-see policy in patients with an asymptomatic hernia. A total of 160 male patients 55 years or older were randomly assigned to observation or operation. Patients were assessed clinically and sent questionnaires at 6 months and 1 year. The primary endpoint was pain and general health status at 12 months; other outcome measures included costs to the health service and the rate of operation for a new symptom or complication. At 12 months, there were no significant differences between the randomized groups of observation or operation, in visual analogue pain scores at rest, 3.7 mm versus 5.2 mm (mean difference, -1.6; 95% confidence interval (CI), -4.8 to 1.6, P = 0.34), or on moving, 7.6 mm versus 5.7 mm (mean difference, -1.9; 95% CI, -6.1 to 2.4, P = 0.39). Also, the number of patients 29 versus 24 (difference in proportion, 8%; 95% CI, -7% to 23%, P = 0.31), who recorded pain on moving and the number taking regular analgesia, 9 versus 17 (difference in proportion, -10%; 95% CI, -21% to 2%, P = 0.14) was similar. At 6 months, there were significant improvements in most of the dimensions of the SF-36 for the operation group, while at 12 months although the trend remained the same the differences were only significant for change in health (mean difference, 7.3; 95% CI, 0.4 to 14.3, P = 0.039). The rate of crossover from observation to operation 23 patients at a median follow-up of 574 days was higher than predicted. The observation group also suffered 3 serious hernia-related adverse events compared with none in the operation group. Repair of an asymptomatic inguinal hernia does not affect the rate of long-term chronic pain and may be beneficial to patients in improving overall health and reducing potentially serious morbidity.

The reporting of gait analysis data on operated fractures of the tibial plateau, while extensive for studies of knee osteoarthritis of mostly undisclosed aetiology and ACL deficient knees, is rather limited in literature. In the present study we investigated 25 tibial plateau fractures classified as Schatzker II, IV, V and VI that underwent operative reduction and lateral plate osteosynthesis. Apart from routine radiographic exploration and patient completed (KOOS) scores at three (mean of 3.2 months), six (mean of 5.6 months) and 12 months (mean of 11.3 months) postoperatively, gait analysis was performed at these intervals as well. Cadence, step time and knee flexion were the gait parameters that were selected for the comparison at six and 12 months postoperatively. The analysed gait parameters were significantly improved between the six and the 12-month session and statistically significant differences were found between the two groups of values. Cadence had a mean value of 41 steps/minute at six months and 45 steps/minute at 12 months (p = 0.99). Step time was a mean of 0.74 seconds at six months while at 12 months the median value was 0.66 seconds (p = 0.94). Knee flexion angles evolved in a similar manner with mean values of 58° at six months and 69° at 12 months (p = 0.95). The mean KOOS scores were 42.4, 56.3 and 67.99 at three, six and 12 months postoperatively, respectively. Complex intra-articular fractures, classified as Schatzker IV, V and VI, had a higher impact on joint function than Schatzker II fractures treated with similar techniques and implants. There were statistically significant improvements in the recovery status at 12 months postoperatively compared to six months with extended chances for improvement.

To analyse sociodemographic, viroimmunological and clinical parameters in different HIV-transmission categories at baseline and during treatment, 3039 patients were followed up for 12 months after the initiation of a nelfinavir-based regimen. Multiple baseline parameters were significantly different in the diverse categories, including CD4 counts (P<0.0001) and viral load (P=0.02). There were differences in the groups regarding the CD4 response (P=0.01), but not the virological response (P=0.4), to therapy over time. Multivariate analyses revealed that transmission categories were significantly related to baseline CD4 counts (P=0.01), viral load at 12 months (P=0.0006), poorer adherence to therapy of injecting drug users (IDUs) vs. each of the other groups (P<0.001) and failure to complete the 12-month evaluation of IDU vs. heterosexual (P=0.003) and men who have sex with men (MSM) groups (P=0.02). We conclude that transmission categories had a significant influence on several baseline parameters and viroimmunological outcomes following highly active antiretroviral therapy (HAART), as well as on adherence to therapy and to medical appointments.

We compared the efficacy of silicone gel (Scarfade), silicone gel sheet (Epi-Derm), and topical onion extract including heparin and allantoin (Contractubex) for the treatment of hypertrophic scars. Forty-five postburn scars were included in the study. Patients with scars less than 6 months from injury were assigned at random to three groups each containing 15 scars, and their treatment was continued for 6 months. Scars were treated with Scarfade, Epiderm and Contractubex. Scar assessment was performed at the beginning of the treatment, and at the end of the sixth month when the treatment was completed by using the Vancouver scar scale. The difference between before and after treatment scores for each three groups was statistically significant. The difference between Scarfade group and Epi-Derm group was not significant; however, the differences of the other groups (Scarfade-Contractubex, Epiderm-Contractubex) were significant. Silicone products, either in gel or sheet, are superior to Contractubex in the treatment of the hypertrophic scar. The therapist should select the most appropriate agent according to the patient's need and guidelines of these signs.

Purpose The purpose of this study was to describe differences in parent input and child vocal behaviors of children with Down syndrome (DS) compared to typically developing (TD) children. The goals were to describe the language learning environments at distinctly different ages in early childhood. Method Nine children with DS and 9 age-matched TD children participated; four children in each group were ages 9–11 months and five were between 25–54 months. Measures were derived from automated vocal analysis. A digital language processer measured the richness of the child’s language environment, including number of adult words, conversational turns, and child vocalizations. Results Analyses indicated no significant differences in words spoken by parents of younger vs. older children with DS, and significantly more words spoken by parents of TD children than parents of children with DS. Differences between the DS and TD groups were observed in rates of all vocal behaviors; with no differences noted between the younger vs. older children with DS, and the younger TD children did not vocalize significantly more than the younger DS children. Conclusions Parents of children with DS continue to provide consistent levels of input across the early language learning years; however, child vocal behaviors remain low after the age of 24 months suggesting the need for additional and alternative intervention approaches.

To compare the attitudes and practices of a sample of veterinarians in New Zealand, Australia and the United Kingdom (UK) towards pre-pubertal gonadectomy of cats. Respondents' demographics were gathered using an electronic questionnaire distributed via professional veterinary associations in the target countries, as were minimum age at gonadectomy and typical age of puberty. Desirability of prepubertal gonadectomy was gauged using three response categories ('yes', 'no' or 'sometimes'), respondents were then able to justify the response given. Two-way Analyses of Variance (ANOVA) followed by post hoc Tukey HSD tests were used to test whether there were differences in minimum ages for gonadectomy within and between countries and between providers and non-providers of services to pounds (or animal welfare centres). Views on the desirability of prepubertal gonadectomy relative to demographics were explored using a Likelihood Ratio Test. The survey received 717 responses. Most respondents believed pre-pubertal gonadectomy was either entirely or 'sometimes' desirable (556/621), few thought it was undesirable (65/621). Minimum age at gonadectomy was significantly affected by country surveyed and provision or non-provision of services for pounds. Post hoc Tukey HSD analysis indicated the mean age of both spaying and castration (4.3 months) in the UK was significantly different from both Australia (spaying: 3.4 months, castration: 3.2 months) and New Zealand (spaying: 3.4 months, castration: 3.2 months) (all p<0.001). Mean ages at spaying and castration were also significantly different (p= 0.008; p= 0.019, respectively) for non-providers (spaying: 3.9 months, castration: 3.8 months) of services to pounds when compared to providers (spaying and castration: both 3.6 months). Likelihood Ratio Tests indicated significant effects amongst countries and between genders relative to the desirability of pre- pubertal gonadectomy. Respondents from the UK were more likely to answer 'no' (p = 0.004) or 'sometimes' (p = 0.050) as compared to those from New Zealand or Australia. Females were more likely to respond with 'sometimes' as opposed to 'yes' than males. Reasons for considering pre-pubertal gonadectomy desirable or sometimes desirable focussed on reducing unwanted pregnancies and improving population control, as well as improving rates of adoption, owner compliance and cat behaviour and health. In general, pre-pubertal gonadectomy is considered a desirable procedure by those practitioners that responded to the survey. However age at which any such procedure occurs differs depending upon a number of factors. Differences among countries may relate to the specific veterinary association's guidelines or possibly differences in social discourse which affect perception of cats. There is substantial overlap between the reported minimum age of gonadectomy and the age at which cats can enter early puberty, allowing a window for unintentional pregnancy when pre-pubertal gonadectomy does not occur.

To analyze 1-week, 1-month, and 12-month postoperative refractive outcomes of eyes that under-went ICL implantation to correct hyperopic astigmatism. The study enrolled 20 eyes of patients with an average age of 32 years (range: 21 to 40 years). The outcomes of spherical and cylindrical refraction, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), vault, and angle parameters were evaluated 1 week, 1 month, and 12 months postoperatively. The preoperative mean UDVA was 0.15 ± 0.11 (decimal) (20/133 Snellen) and increased to 0.74 ± 0.25 (20/27 Snellen) postoperatively, with a change of 0.59 (decimal) (20/33.9 Snellen) (P < .0001), which was statistically significant. The preoperative mean CDVA was 0.74 ± 0.25 (decimal) (20/27 Snellen) and increased to 0.78 ± 0.21 (20/25 Snellen), with a change of 0.03 (decimal) (20/666 Snellen) (P < .052), which was not statistically significant. The mean preoperative sphere was 6.86 ± 1.77 diopters (D) and the mean preoperative cylinder was -1.44 ± 0.88 D. The mean 12-month postoperative sphere decreased to 0.46 ± 0.89 D (P < .001) and cylinder decreased to -0.61 ± 0.46 D (P < .001), with a change of 6.40 D, both of which were statistically significant. The mean 1-month postoperative vault was 0.65 ± 0.13 mm and decreased to 0.613 ± 0.10 mm at 1 year postoperatively, with a change of 0.44 mm (P < .003). The preoperative/12-month and 1-month/12-month trabecular-iris angle (TIA), trabecular-iris space area 500 mm from the scleral spur (TISA500), and angle opening distance 500 mm from the scleral spur (AOD500) values were analyzed nasally, temporally, and inferiorly. All differences were statistically significant between preoperative/12-month analysis. The only differences between 1- and 12-month analysis were on TISA500 inferior (P < .002) and AOD500 nasal (0.031) values. ICL hyperopic toric implantation is a safe method and provides stable refractive outcomes in patients with high hyperopia (up to 10.00 D) and astigmatism (up to 6.00 D).

To understand the status of mizoribine use in patients with lupus nephritis (LN) and to collect safety- and efficacy-related data on 2-year treatment with mizoribine. A continuous survey was conducted between March 2010 and July 2015. The analysis set included 559 patients (mean age 39.5 years, females 82.6%, mean duration of systemic lupus erythematosus (SLE) 8.4 years, mean duration of LN 5.9 years). Renal function was satisfactory for 6 months, but worsened from 12 months, with significant worsening at 24 months. By the ACR 2006 remission criteria (eGFR >60), at 24 months, 26.5% of patients achieved complete remission, and 63.3% achieved complete or partial remission. The urine protein to creatinine ratio decreased significantly. The SLE Disease Activity Index 2000 score decreased significantly at 12 and 24 months. Overall, 98 (17.5%) patients experienced 124 adverse drug reactions (ADRs); 3.6% experienced serious ADRs. Mizoribine was used with a steroid in 99.3% and an immunosuppressant in 51.2%; tacrolimus was used in 43.8%. The oral steroid dosage decreased from baseline to 24 months. The incidence of ADRs was not significantly different with concomitant tacrolimus use. The results suggest that long-term mizoribine is safe and effective, even when used with tacrolimus.

We systematically evaluated changes in availability, price, and quality of perishable food items from the beginning to the end of the month in lowincome, urban neighborhoods. The sample included grocery stores or supermarkets in Cleveland, Ohio, within neighborhoods with >30% of population receiving food assistance. We collected data for 2 sequential months during the first and fourth weeks of each month. Two coders evaluated stores, collecting measures of availability, price, and quality for 50 items. We examined difference in number and proportion of items available at the beginning of the month (BOM) to items remaining available at the end of the month (EOM), as well as quality and price of those items. Across 48 stores, availability at EOM was lower than BOM; as store size increased, reduction in availability (ie, food melt) was significantly (p < .01) less pronounced. Overall, items became less expensive at the EOM whereas quality remained consistent; we noted no statistically significant differences by store type for price or quality. Food melt differentially affects individuals in neighborhoods without grocery stores. Findings reveal composition of food environments is dynamic rather than static, influencing food-purchasing choices among lowincome consumers.

Impaired mobility, such as falls, may be an early biomarker of subsequent cognitive decline and is associated with subclinical alterations in both brain structure and function. In this 12-month prospective study, we examined whether there are volumetric differences in gray matter and subcortical regions, as well as cerebral white matter, between older fallers and non-fallers. In addition, we assessed whether these baseline volumetric differences are associated with changes in cognitive function over 12 months. A total of 66 community-dwelling older adults were recruited and categorized by their falls status. Magnetic resonance imaging occurred at baseline and participants’ physical and cognitive performances were assessed at baseline and 12-months. At baseline, fallers showed significantly lower volumes in gray matter, subcortical regions, and cerebral white matter compared with non-fallers. Notably, fallers had significantly lower left lateral orbitofrontal white matter volume. Moreover, lower left lateral orbitofrontal white matter volume at baseline was associated with greater decline in set-shifting performance over 12 months. Our data suggest that falls may indicate subclinical alterations in regional brain volume that are associated with subsequent decline in executive functions. PMID:27079333

Polycystic ovary syndrome (PCOS) is associated with obesity and increased cardiovascular (CV) risk markers. In this study our aim was to assess the effects of six months treatment with liraglutide 1.8 mg od on obesity, and CV risk markers, particularly platelet function, in young obese women with PCOS compared to controls of similar age and weight. Carotid intima-media wall thickness (cIMT) was measured by B-mode ultrasonography, platelet function by flow cytometry, clot structure/lysis by turbidimetric assays and endothelial function by ELISA and post-ischaemic reactive hyperemia (RHI). Data presented as mean change (6-month - baseline) ± standard deviation. Nineteen obese women with PCOS and 17 controls, of similar age and weight, were recruited; baseline atherothrombotic risk markers did not differ between the two groups. Twenty five (69.4%) participants completed the study (13 PCOS, 12 controls). At six months, weight was significantly reduced by 3.0 ± 4.2 and 3.8 ± 3.4 kg in the PCOS and control groups, respectively; with no significant difference between the two groups, P = 0.56. Similarly, HOMA-IR, triglyceride, hsCRP, urinary isoprostanes, serum endothelial adhesion markers (sP-selectin, sICAM and sVCAM), and clot lysis area were equally significantly reduced in both groups compared to baseline. Basal platelet P-selectin expression was significantly reduced at six months in controls -0.17 ± 0.26 but not PCOS -0.12 ± 0.28; between groups difference, 95% confidence interval = -0.14 - 0.26, P = 0.41. No significant changes were noted in cIMT or RHI. Six months treatment with liraglutide (1.8 mg od) equally affected young obese women with PCOS and controls. In both groups, liraglutide treatment was associated with 3-4% weight loss and significant reduction in atherothrombosis markers including inflammation, endothelial function and clotting. Our data support the use of liraglutide as weight loss medication in simple obesity and suggest a potential beneficial effect on platelet function and atherothrombotic risk at 6 months of treatment.

Love, Jeffrey J.; Thomas, Jeremy N.

We examine the claim that solar-terrestrial interaction, as measured by sunspots, solar wind velocity, and geomagnetic activity, might play a role in triggering earthquakes. We count the number of earthquakes having magnitudes that exceed chosen thresholds in calendar years, months, and days, and we order these counts by the corresponding rank of annual, monthly, and daily averages of the solar-terrestrial variables. We measure the statistical significance of the difference between the earthquake-number distributions below and above the median of the solar-terrestrial averages by χ2 and Student's t tests. Across a range of earthquake magnitude thresholds, we find no consistent and statistically significant distributional differences. We also introduce time lags between the solar-terrestrial variables and the number of earthquakes, but again no statistically significant distributional difference is found. We cannot reject the null hypothesis of no solar-terrestrial triggering of earthquakes.

To compare the likelihood of being within weight standards before and after pregnancy between United States Marine Corps (USMC) and Navy (USN) active duty women (ADW). ADW with singleton gestations who delivered at a USMC base were followed for 6 months to determine likelihood of returning to military weight standards. Odds ratio (OR), adjusted odds ratio (AOR) and 95% confidence intervals were calculated; p < 0.05 was considered significant. Similar proportions of USN and USMC ADW were within body weight standards one year prior to pregnancy (79%, 97%) and at first prenatal visit (69%, 96%), respectively. However, USMC ADW were significantly more likely to be within body weight standards at 3 months (AOR 4.30,1.28-14.43) and 6 months after delivery (AOR 9.94, 1.53-64.52) than USN ADW. Weight gained during pregnancy did not differ significantly for the two groups (40.4 lbs vs 44.2 lbs, p = 0.163). The likelihood of spontaneous vaginal delivery was significantly higher (OR 2.52, 1.20-5.27) and the mean birth weight was significantly lower (p = 0.0036) among USMC ADW as compared to USN ADW. Being within weight standards differs significantly for USMC and USN ADW after pregnancy.

The aim of this study was to evaluate both the short-term and the long-term effectiveness of spa therapy in patients with primary hand osteoarthritis (OA). This was a prospective randomized, single blind controlled trial. Sixty outpatients with primary bilateral hand OA were included in the study and randomized to one of two groups. One group ( n = 30) was treated with 12 daily local mud packs and generalized thermal baths with a sulfate-calcium-magnesium-fluorides mineral water added to usual treatment. The control group ( n = 30) continued regular outpatient care routine (exercise, NSAIDs and/or analgesics). Each patient was examined at baseline, after 2 weeks, and after 3, 6, 9 and 12 months. Primary outcome measures were global spontaneous hand pain on a visual analogue scale (VAS) and the functional index for hand osteoarthritis (FIHOA) score; secondary outcomes were health assessment questionnaire (HAQ), duration of morning stiffness, medical outcomes study 36-item short form (SF-36) and symptomatic drugs consumption. Our results demonstrated that the efficacy of spa therapy was significant in all the assessed parameters, both at the end of therapy and after 3 months; the values of FIHOA, HAQ and drugs consumption continued to be significantly better after 6 months in comparison with baseline. There were no significant modifications of the parameters throughout the follow-up in the control group. Differences between the two groups were significant for all parameters at the 15th day and at 3 months follow-up; regarding FIHOA, HAQ, and symptomatic drugs consumption, the difference between the two groups persisted and was significant at 6month follow-up. Tolerability of spa therapy seemed to be good. In conclusion, our results confirm that the beneficial effects of spa therapy in patients with hand OA last over time.

Childhood caries have a high relapse rate after full mouth therapy. This study aimed to elucidate the relationship between the microbiome, sugar, and the relapse of childhood caries after therapy. A total of 24 children aged 2-4 years who underwent one caries treatment session participated in this study. Supragingival plaque was collected before therapy and 1 and 7 months after therapy, then sequenced using the 16S rRNA high-throughput approach. We found 11 phyla, 140 genera, and 444 species in 72 samples. The children were divided into relapse-free (n = 13) and relapse (n = 11) groups according to whether they relapsed 7 months after therapy. The bacterial community richness, diversity, structure, and relative abundance of bacterial taxa were significantly different between the two groups 7 months after therapy. The two groups also differed in the relative abundance of bacterial taxa, both before and 1 month after therapy. Bacterial community richness and diversity were lower in the relapse-free group 1 month after therapy. Using different operational taxonomic units between the relapse-free and relapse groups 1 month after therapy, a relapse-risk assessment model was built with 75% accuracy, 0.1905 out-of-bag error, and 66.67% validation accuracy. Patients in the relapse group had higher sugar intake frequencies than those in the relapse-free group during follow-up. Interactions between the microbiome and sugar intake frequency were found through co-occurrence networks. We conclude that the microbiome is significantly different between the relapse-free and relapse groups at the time of relapse. Supragingival plaque collected immediately after therapy can be used to predict the risk of relapse. Furthermore, the correlation between sugar intake frequency and microbiome is associated with the relapse. Copyright © 2015 Elsevier Inc. All rights reserved.

[Analysis of the Effect of Non-phacoemulsification Cataract Operation on Corneal Endothelial Cell Nucleus Division].

To investigate the effect of non-phacoemulsification cataract operation in two different patterns of nucleus delivery on the quantity and morphology of corneal endothelial cells and postoperative visual acuity. Forty patients diagnosed with cataract underwent cataract surgery and were assigned into the direct nuclear delivery and semi-nuclear delivery groups. Lens density was measured and divided into the hard and soft lenses according to Emery-little lens nucleus grading system. Non-phacoemulsification cataract operation was performed. At 3 d after surgery, the quantity and morphology of corneal endothelium were counted and observed under corneal endothelial microscope. During 3-month postoperative follow-up, the endothelial cell loss rate, morphological changes and visual acuity were compared among four groups. Corneal endothelial cell loss rate in the direct delivery of hard nucleus group significantly differed from those in the other three groups before and 3 months after operation (P < 0.01), whereas no statistical significance was found among the direct delivery of soft nucleus, semi-delivery of hard nucleus and semi-delivery soft nucleus groups (all P > 0.05). Preoperative and postoperative 2-d visual acuity did not differ between the semi-delivery of hard nucleus and direct delivery of soft nucleus groups (P = 0.49), significantly differed from those in the semi-delivery of soft nucleus (P = 0.03) and direct delivery of hard nucleus groups (P = 0.14). Visual acuity at postoperative four months did not differ among four groups (P = 0.067). During non-phacoemulsification cataract surgery, direct delivery of hard nucleus caused severe injury to corneal endothelium and semi-delivery of soft nucleus yielded mild corneal endothelial injury. Slight corneal endothelial injury exerted no apparent effect upon visual acuity and corneal endothelial morphology at three months after surgery.

A significant proportion of trauma survivors experience an additional critical life event in the aftermath. These renewed experiences of traumatic and stressful life events may lead to an increase in trauma-related mental health symptoms. In a longitudinal study, the effects of renewed experiences of a trauma or stressful life event were examined. For this purpose, refugees seeking asylum in Germany were assessed for posttraumatic stress symptoms (PTS), Posttraumatic Stress Diagnostic Scale (PDS), anxiety, and depression (Hopkins Symptom Checklist [HSCL-25]) before treatment start as well as after 6 and 12 months during treatment ( N =46). Stressful life events and traumatic events were recorded monthly. If a new event happened, PDS and HSCL were additionally assessed directly afterwards. Mann-Whitney U -tests were performed to calculate the differences between the group that experienced an additional critical event (stressful vs. trauma) during treatment ( n =23) and the group that did not ( n =23), as well as differences within the critical event group between the stressful life event group ( n =13) and the trauma group ( n =10). Refugees improved significantly during the 12-month period of our study, but remained severely distressed. In a comparison of refugees with a new stressful life event or trauma, significant increases in PTS, anxiety, and depressive symptoms were found directly after the experience, compared to the group without a renewed event during the 12 months of treatment. With regard to the different critical life events (stressful vs. trauma), no significant differences were found regarding overall PTS, anxiety, and depression symptoms. Only avoidance symptoms increased significantly in the group experiencing a stressful life event. Although all clinicians should be aware of possible PTS symptom reactivation, especially those working with refugees and asylum seekers, who often experience new critical life events, should understand symptom fluctuation and address it in treatment.

To observe the therapeutic efficacy of bronchoscopic interventional therapy on severe tuberculous main bronchial stenosis or atresia complicated with unilateral atelectasis. Ninety patients with severe tuberculous main bronchial stenosis or atresia complicated with unilateral atelectasis, who had received bronchoscopic interventional therapy, were divided into group A and B according to whether stents had been implanted or not. Patients in group A had been treated with electrocautery, balloon dilatation and cryotherapy. Group B had been treated with metallic stent implantation on the basis of the above interventional management. In order to observe the effectiveness, the time needed for taking effect and restenosis rate were noted. The efficacy between patients with different disease courses, radiology, bronchoscopy and dyspnea index were evaluated before treatment and after the patients' conditions were stable. Three months after treatment, the good response rate and the total effective rate of group B were higher than those of group A, 97% vs 42% (χ(2) = 29.595, P < 0.05), 100% vs 81% (χ(2) = 6.060, P < 0.05), respectively. The time needed for taking effect in group B was significantly shorter than that in group A, 0.25 month vs 1.6 month. The dyspnea indexes of both groups were significantly improved after treatment, but the improvement of group B was more significant than that of group A (u = -2.478, P < 0.05). The disease course of patients with different therapeutic efficacy was evaluated, and the median disease course was 2 months in good response efficacy patients, 3.5 months in improved patients, and 5 months in ineffective patients; the difference being significant between ineffective and good response efficacy patients (u = -3.079, P < 0.01). The restenosis rate of group B was significantly higher than that of group A, 72% vs 32% (χ(2) = 9.090, P < 0.01). The median restenosis time was 4 months in group A, and 6 months in group B. Bronchoscopy follow-up 12 months after the initial effective treatment showed that the good response rate and the total effective rate of group B were better than those of group A, 60% vs 29% (χ(2) = 10.559, P < 0.01), 88% vs 60% (χ(2) = 10.261, P < 0.01, respectively), and the total effective rate of main bronchial atresia patients in group B was significantly higher than that in group A, 90% vs 50% (Fisher's exact test, P < 0.05). There was no significant difference in effectiveness between severe stenosis and atresia patients in group A and B. Electrocautery, balloon dilatation, cryotherapy and stent implantation were effective methods to treat severe tuberculous main bronchial stenosis or atresia complicated with unilateral atelectasis. Among them, the therapeutic efficacy was better and the symptoms improved more quickly in patients with stent implantation. The efficacy of stent implantation was better than that of conventional interventional therapy, but the incidence of restenosis was also higher. Following-up should be emphasized in this group of patients. Disease courses were associated with the therapeutic efficacy; longer disease course was related to worse therapeutic efficacy, and restenosis occurred earlier. So interventional therapy should be initiated earlier for bronchial tuberculosis with dyspnea, especially for that complicated by atelectasis.

Objectives. To determine the prevalence, the clinical predictors, and the prognostic significances of Worsening Renal Function (WRF) in hospitalized patients with Acute Heart Failure (AHF). Methods. 394 consecutively hospitalized patients with AHF were evaluated. WRF was defined as an increase in serum creatinine of ≥0.3 mg/dL from baseline to discharge. Results. Nearly 11% of patients developed WRF. The independent predictors of WRF analyzed with a multivariable logistic regression were history of chronic kidney disease (P = .047), age >75 years (P = .049), and admission heart rates ≥100 bpm (P = .004). Mortality or rehospitalization rates at 1 month, 6 months, and 1year were not significantly different between patients with WRF and those without WRF. Conclusion. Different clinical predictors at hospital admission can be used to identify patients at increased risk for developing WRF. Patients with WRF compared with those without WRF experienced no significant differences in hospital length of stay, mortality, or rehospitalization rates.

IMPORTANCE For many older people, long-term functional limitations persist after a hip fracture. The efficacy of a home exercise program with minimal supervision after formal hip fracture rehabilitation ends has not been established. OBJECTIVE To determine whether a home exercise program with minimal contact with a physical therapist improved function after formal hip fracture rehabilitation ended. DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial conducted from September 2008 to October 2012 in the homes of 232 functionally limited older adults who had completed traditional rehabilitation after a hip fracture. INTERVENTIONS The intervention group (n = 120) received functionally oriented exercises (such as standing from a chair, climbing a step) taught by a physical therapist and performed independently by the participants in their homes for 6 months. The attention control group (n = 112) received in-home and telephone-based cardiovascular nutrition education. MAIN OUTCOMES AND MEASURES Physical function assessed at baseline, 6 months (ie, at completion of the intervention), and 9 months by blinded assessors. The primary outcome was change in function at 6 months measured by the Short Physical Performance Battery (SPPB; range 0-12, higher score indicates better function) and the Activity Measure for Post-Acute Care (AM-PAC) mobility and daily activity (range, 23-85 and 9-101, higher score indicates better function). RESULTS Among the 232 randomized patients, 195 were followed up at 6 months and included in the primary analysis. The intervention group (n=100) showed significant improvement relative to the control group (n=95) in functional mobility (mean SPPB scores for intervention group: 6.2 [SD, 2.7] at baseline, 7.2 [SD, 3] at 6 months; control group: 6.0 [SD, 2.8] at baseline, 6.2 [SD, 3] at 6 months; and between-group differences: 0.8 [95% CI, 0.4 to 1.2], P < .001; mean AM-PAC mobility scores for intervention group: 56.2 [SD, 7.3] at baseline, 58.1 [SD, 7.9] at 6 months; control group: 56 [SD, 7.1] at baseline, 56.6 [SD, 8.1] at 6 months; and between-group difference, 1.3 [95% CI, 0.2 to 2.4], P = .03; and mean AM-PAC daily activity scores for intervention group: 57.4 [SD, 13.7] at baseline, 61.3 [SD, 15.7] at 6 months; control group: 58.2 [SD, 15.2] at baseline, 58.6 [SD, 15.3] at 6 months; and between-group difference, 3.5 [95% CI, 0.9 to 6.0], P = .03). In multiple imputation analyses, between-group differences remained significant for SPPB and AM-PAC daily activity, but not for mobility. Significant between-group differences persisted at 9 months for all functional measures with and without imputation. CONCLUSIONS AND RELEVANCE Among patients who had completed standard rehabilitation after hip fracture, the use of a home-based functionally oriented exercise program resulted in modest improvement in physical function at 6 months after randomization. The clinical importance of these findings remains to be determined. PMID:24549550

Bone disease with persistent reduced bone mineralisation is common in premature infants. To test the hypothesis that enhancement of nutritional intake after discharge from hospital improves bone mineralisation, 31 formula fed preterm infants were randomly assigned to receive standard or multinutrient enriched milk from the time of discharge. The calcium and phosphorus contents of the enriched milk were 70 and 35 mg/100 ml v 35 and 29 mg/100 ml for the standard formula. Bone mineral content was measured before discharge from hospital in 21 of the infants; there was no difference in the bone mineral content between the groups at that time (35 mg/cm for the two groups). There was a significant increase in bone mineral content for those infants receiving the enriched v standard formula at 3 and 9 months corrected postnatal age: at 3 months the bone mineral content was 83 v 63 mg/cm and at 9 months 115 v 95 mg/cm. The difference between the groups was thus maintained although not increased at a corrected age of 9 months, when the bone mineral content of infants fed the enriched but not the standard formula was no longer significantly different from that of normal infants after adjusting for body size. The difference was not explained by the larger body size in infants fed the enriched formula. The results suggest that the use of a special nutrient enriched postdischarge formula has a significant positive effect on bone growth and mineralisation during a period of rapid skeletal development.

Residual renal function (RRF) is an important determinant of mortality and morbidity in patients receiving peritoneal dialysis (PD). Recent studies have shown a positive effect of angiotensin converting enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARBs) on RRF in PD patients. To compare enalapril and losartan for RRF preservation in automated peritoneal dialysis (APD) patients. An open label randomized controlled trial (RCT) with a 12 month follow-up period was conducted to compare the effect of enalapril vs. losartan on RRF preservation in 60 APD patients. Measurements were done at the start of the study (baseline), 3, 6, 9, and 12 months. A historical control group (HCG) without treatment was included to assess the natural history of RRF loss. RRF in the enalapril group dropped from 3.65 +/- 1.6 (baseline) to 2.36 +/- 0.38 mL/min/1.73 m2 (12 months). In the losartan group RRF was reduced from 4.1+/- 2.01 (baseline) to 2.54 +/- 0.47 mL/min/ 1.73 m2 (12 months). There were not significant differences between the two groups regarding RRF at 12 months. In the HCG, RRF declined from 3.68 +/- 0.48 to 1.4 +/- 0.29 mL/min/ 1.73 m2 (12 months). RRF in the HCG was significantly lower than RRF in the two treated groups at 12 months (P < 0.05). There was not significant difference on RRF preservation between enalapril and losartan groups. Comparing these results to those of the HCG suggests that the treatment with any of the drugs is useful in preserving RRF.

The Step by Step self-help walking program plus a pedometer previously motivated a community sample of adults to be physically active for up to three months. This study evaluates the effect of enhancement of this program over an additional nine months in a workplace. A quasi-experimental trial was conducted. Staff defined as inactive received the three month walking program and a pedometer (standard), or the three month program plus four maintenance newsletters over nine months (standard+maintenance). After 12 months a follow-up interview was conducted. Measures included changes in self-reported minutes walking, minutes of moderate-vigorous physical activity (MVPA), total physical activity (PA) in the past week, and the proportion meeting public health recommendations by walking and total PA. Significant increases on all outcome measures were noted for all participants. There were no between group differences in walking minutes. However, the change in MVPA minutes was significantly higher in the standard+maintenance group compared with the standard group (118 min vs 69 min, P=0.029). No significant between group differences were observed for total PA (161 min vs 117 min, P=0.187). Wearing the pedometer at the month of the follow-up interview, and thinking that the pedometer was very useful, increased the likelihood of meeting public health recommendations (AOR=2.7 and 2.5) adjusting for other covariates. Dissemination of the Step by Step guidebook with pedometers in the workplace resulted in a long-term increase in PA of inactive employees with no extra support. Newsletters as a maintenance strategy had no additional benefits. Better outcomes were noted if the pedometer was used and was perceived as being very useful.

Malocclusion is a common disease of oral and maxillofacial region. The study was aimed to investigate levels changes of periodontal pathogens in malocclusion patients before, during and after orthodontic treatments, and to confirm the difference between adults and children. One hundred and eight malocclusion patients (46 adults and 62 children at the school-age) were randomly selected and received orthodontic treatment with fixed orthodontic appliances. Subgingival plaques were Porphyromonas gingivalis (P.gingivalis), Fusobacterium nucleatum (F. nucleatum), Prevotella intermedia (P. intermedia) and Tannerella forsythensis (T. forsythensis) collected from the observed regions before and after treatment. Clinical indexes, including plaque index (PLI), gingival index (GI), sulcus bleeding index (SBI), probing depth (PD) and attachment loss (AL) of observed teeth were examined. The detection rates of P.gingivalis, F. nucleatum, P. intermedia and T. forsythensis increased from baseline to the third month without significant difference, and then returned to pretreatment levels 12 month after applying fixed orthodontic appliances. Adults' percentage contents of P.gingivalis, F. nucleatum, P. intermedia and T. forsythensis were significantly higher than those of children at baseline and the first month, but not obvious at the third month. PLI and SBI were increased from baseline to the first and to the third month both in adults and children groups. Besides, PD were increased from baseline to first month, followed by a downward trend in the third month; however, all patients were failed to detect with AL. Periodontal and microbiological statuses of malocclusion patients may be influenced by fixed orthodontic appliances in both adults and children, more significant in children than in adults. Some microbiological indexes have synchronous trend with the clinical indexes. Long-term efficacy of fixed orthodontic appliances for malocclusion should be confirmed by future researches.

The aim of this study was to investigate the development of mother-infant interaction patterns from 3 to 12 months among three groups of mother-baby pairs recruited during pregnancy: one group from residential substance abuse treatment (n=28), a second group from psychiatric outpatient treatment (n=22), and a third group from well-baby clinics (n=30). The mother-infant interaction at 3 and 12 months was assessed by the Parent-Child Early Relational Assessment (PCERA), which consists of maternal, child and dyadic subscales (Clark, 2006). Linear mixed effects models were used to analyze group differences and the changes in mother-infant interaction from 3 to 12 months. At 3 months, pairwise comparisons showed that the group with psychiatric problems had significantly more difficulties in the mother-infant interaction than the two other groups. The group with substance abuse problems was not significantly different from the two other groups. At 12 months, the mother-infant pairs in the substance abuse group showed significantly more relational disturbances than the non-clinical pairs, as well as a poorer affective quality of interaction than the dyads in the group with psychiatric problems. Analysis of change from 3 to 12 months showed that difficulties in the interaction increased among the mother-baby pairs in the substance abuse group, while improvements were displayed in the two other groups. These results underline that mother-infant pairs at double risk due to maternal substance abuse and other non-optimal factors, are in need for long-term follow up in order to prevent the development of negative interactional patterns.

The purpose of this study was to DNA fingerprint the majority (64%) of isolates received at the Pertussis Reference Laboratory during the 1993 whooping cough epidemic by pulsed field gel electrophoresis of Xba I-generated restriction digests. Two DNA restriction patterns, types 1 and 3, predominated (40% and 23%, respectively, of 180 isolates) but type 2, identified in a previous study was notably absent. Twenty-one new DNA types occurred (24% of isolates), some being atypical as bands 155-230 kb were no longer conserved, but there was no statistically significant difference in their incidence in the upswing (June-September) compared to the downswing (October-December) phase of the epidemic. There was a relatively high proportion of new types, compared to type 1, at the peak (September). About 50% of isolates received were from the North Western Region, where 44% of isolates were DNA type 1. Whereas only 1 out of 10 isolates from Scotland were of this type, suggesting some geographic variation. Statistically significant findings included a higher proportion of isolates from female patients (P < 0.01), most marked in the 12-24 months age group (P < 0.05); a higher proportion of infants under 12 months requiring hospital admission compared to older children (P < 0.05); and a greater number of isolates from unvaccinated children (P < 0.01). Analysis of serotype according to four age groups (under 3 months, 3-12 months, 12-24 months and above 2 years) showed statistically significant differences (P < 0.05) with a noticeably lower proportion (38%) of serotype 1,3 in 3-12 months age group and higher prevalence (74%) of serotype 1,3 in the 12-24 months age group. There was no correlation between DNA type and serotype. Images Fig. 2 PMID:7641824

Optometric practices offer contact lenses as cash sale items or as part of monthly payment plans. With the contact lens market becoming increasingly competitive, patients are opting to purchase lenses from supermarkets and Internet suppliers. Monthly payment plans are often implemented to improve loyalty. This study aimed to compare behavioural loyalty between monthly payment plan members and non-members. BBR Optometry Ltd offers a monthly payment plan (Eyelife™) to their contact lens wearers. A retrospective audit of 38 Eyelife™ members (mean±SD: 42.7±15.0 years) and 30 non-members (mean±SD: 40.8±16.7 years) was conducted. Revenue and profits generated, service uptake and product sales between the two groups were compared over a fixed period of 18 months. Eyelife™ members generated significantly higher professional fee revenue (P<0.001), £153.96 compared to £83.50, and profits (P<0.001). Eyelife™ members had a higher uptake of eye examinations (P<0.001). The 2 groups demonstrated no significant difference in spectacle sales by volume (P=0.790) or value (P=0.369). There were also no significant differences in contact lens revenue (P=0.337), although Eyelife™ members did receive a discount. The Eyelife™ group incurred higher contact lens costs (P=0.037), due to a greater volume of contact lens purchases, 986 units compared to 582. Monthly payment plans improve loyalty among contact lens wearers, particularly service uptake and volume of lens purchases. Additionally the greater professional fees generated, render monthly payment plans an attractive business model and practice builder. Copyright © 2014 British Contact Lens Association.

Mesh repair has significantly reduced recurrence rate after groin hernia surgery. Recently, attention has shifted to issues such as chronic pain and discomfort, leading to development of lightweight and partially re-absorbable meshes. The aim of the study was to evaluate the effect of lightweight mesh vs heavyweight mesh on post-operative pain, discomfort and quality of life in short and medium term after inguinal hernia surgery. Eight hundred and eight patients with primary inguinal hernia were allocated to anterior repair (Lichtenstein technique) using a lightweight mesh (Ultrapro ® ) or a heavyweight mesh (Prolene ® ). Primary outcomes were incidence of chronic pain and discomfort at 6-month follow-up. Secondary endpoints were quality of life (QoL), pain and complication at 1 week, 1 and 6 months. At 6 months, 25% of patients reported pain of some intensity; severe pain was reported by 1% of patients in both groups. A statistically significant difference in favour of lightweight mesh was found at multivariable analysis for pain (1 week and 6 months after surgery: p = 0.02 and p = 0.04, respectively) and QoL at 1 month and 6 months (p = 0.05 and p = 0.02, respectively). There was no difference in complication rate and no hernia recurrences were detected. The use of lightweight mesh in anterior Lichtenstein inguinal hernia repair significantly reduced the incidence of pain and favourably affected the perceived quality of life at 6 months after surgery compared to heavyweight mesh.

To evaluate the effect of uterine artery embolization (UAE) and hysterectomy on ovarian function. Prospective case control study (Canadian Task Force classification II-2). University teaching hospital. Eighty-four healthy premenopausal women with symptomatic uterine myoma(s) undergoing UAE or hysterectomy. Patients had blood drawn to measure follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) levels and underwent transvaginal ultrasound to measure volume of the myoma(s) and uterus on cycle day 3 before the procedures. These measurements were repeated 3 and 6 months after treatment. The main outcome was the differences in serum FSH, LH, E2, and ultrasound findings before and after UAE or hysterectomy. Of the 68 patients who underwent UAE and 16 who underwent hysterectomy, 48 and 13 respectively, completed 6-month follow-up. The mean age of the patients in the UAE group was 44.9 +/- 3.8 years and 43.7 +/- 5.6 years in the hysterectomy group. There was no significant difference in serum FSH before (8.9 +/- 0.7 IU/L) and 6 months after UAE (9.9 +/- 1.0 lU/L), and between the baseline (10.4 +/- 1.8 lU/L) and 6 months posthysterectomy (7.8 +/- 1.8 lU/L). The uterine volume 6 months after UAE (361 +/- 50 mL) was significantly smaller than before UAE(538 +/- 38mL; p =.005, 95% CI 44-241). Compared with baseline (154 +/- 20 mL), the dominant myoma volume was smaller at 6 months after UAE (97 +/- 16 mL; p <.05, 95% CI 1.57-62). Uterine artery embolization is associated with a significant reduction in myoma and uterine volume. Ovarian function at 6 months, as indicated by day 3 FSH levels, is not affected by UAE or hysterectomy.

Viscosupplementation has been widely used for the treatment of knee osteoarthritis. Because we found no well-controlled trial comparing single-injection regimens of hyaluronan for knee osteoarthritis, we compared the efficacy and safety of a single intra-articular injection of a novel cross-linked hyaluronan (HYA-JOINT Plus) with a single injection of Synvisc-One in patients with knee osteoarthritis. In a prospective, randomized, controlled, double-blind trial with a 6-month follow-up, 132 patients with knee osteoarthritis (Kellgren-Lawrence grade 2 or 3) were randomized to receive 1 intra-articular injection of 3 mL of HYA-JOINT Plus (20 mg/mL) (n = 66) or 6 mL of Synvisc-One (8 mg/mL) (n = 66). The primary outcome was the change from baseline in the visual analog scale (VAS) (0 to 100 mm) pain score at 6 months. Secondary outcome measures included the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC, Likert scale), Lequesne index, timed "Up & Go" (TUG) test, single-limb stance (SLS) test, use of rescue analgesics, and patient satisfaction. A total of 121 patients were available for the intention-to-treat analysis at 6 months. Both groups had a significant improvement in the VAS, WOMAC, and Lequesne index scores at each follow-up visit (p < 0.001). Patients who received HYA-JOINT Plus experienced a significantly greater improvement in the VAS pain score at 1, 3, and 6 months compared with those treated with Synvisc-One (adjusted mean difference: -12.0, -8.5, and -6.6; p = 0.001, 0.033, and 0.045, respectively). There were no significant between-group differences in any of the secondary outcomes except the WOMAC stiffness scores at 6 months, which favored HYA-JOINT Plus treatment (p = 0.043). The TUG time did not change significantly in either group during the study (p > 0.05), but the SLS time improved significantly in both the HYA-JOINT Plus and the Synvisc-One group (p = 0.004 and p = 0.022, respectively). No significant between-group differences were observed with respect to patient satisfaction or consumption of analgesics. No serious adverse events occurred following the injections. A single injection of either HYA-JOINT Plus or Synvisc-One is safe and effective for 6 months in patients with knee osteoarthritis. HYA-JOINT Plus is superior to Synvisc-One in terms of reducing the VAS pain score at 1, 3, and 6 months and the WOMAC stiffness score at 6 months, with similar safety. Therapeutic Level I.

To compare the effect of incomplete caries removal (ICR) and indirect pulp capping (IPC) with calcium hydroxide (CH) or an inert material (wax) on color, consistency and contamination of the remaining dentin of primary molars. This double-blind, parallel-design, randomized controlled trial included 30 children presenting one primary molar with deep caries lesion. Children were randomly assigned after ICR to receive IPC with CH or wax. All teeth were then restored with resin composite. Baseline dentin color and consistency were evaluated after ICR, and dentin samples were collected for contamination analyses using scanning electron microscopy. After 3 months, restorations were removed and the three parameters were re-evaluated. In both groups, dentin became significantly darker after 3 months. No cases of yellow dentin were observed after 3 months with CH compared to 33.3% of the wax cases (P < 0.05). A statistically significant difference over time was observed only for CH regarding consistency. CH stimulated a dentin hardening process in a statistically higher number of cases than wax (86.7% vs. 33.3%; P = 0.008). Contamination changed significantly over time in CH and wax without significant difference between groups. It was concluded that CH and wax arrested the carious process of the remaining carious dentin after indirect pulp capping, but CH showed superior dentin color and consistency after 3 months.

Although pulsed radiofrequency (PRF) method for lumbosacral radicular pain (LSRP) is reportedly effective, there are no prospective controlled trials. We assessed the long-term efficacy of PRF of the dorsal root ganglion and nerve roots for LSRP as compared with nerve root block (RB). The study included 27 patients suffering from LSRP. The design of this study was randomized with a RB control. In the PRF group, the PRF current was applied for 120 seconds after RB. In the RB group, the patients received RB only. Visual analogue scale (VAS) was assessed immediately before, and immediately, 2 hours, 1 day, 1 week, 1 month, 3 months, 6 months, and 1 year after the procedure. P<0.05 was regarded as denoting statistical significance. In both groups, the VAS not only of short-term but also of long-term (6 months and 1 year after procedure) significantly decreased as compared with that before treatment (P<0.05). There were no significant differences of VAS between the two groups at the same time points. This study indicates that PRF adjacent to the dorsal root ganglion and nerve roots for LSRP has long-term effects. There were no significant differences of long-term effects between the two groups.

To assess the cost-utility of an exercise programme vs usual care after functional multidisciplinary rehabilitation in patients with chronic low back pain. Cost-utility analysis alongside a randomized controlled trial. A total of 105 patients with chronic low back pain. Chronic low back pain patients completing a 3-week functional multidisciplinary rehabilitation were randomized to either a 3-month exercise programme (n = 56) or usual care (n = 49). The exercise programme consisted of 24 training sessions during 12 weeks. At the end of functional multidisciplinary rehabilitation and at 1-year follow-up quality of life was measured with the SF-36 questionnaire, converted into utilities and transformed into quality--adjusted life years. Direct and indirect monthly costs were measured using cost diaries. The incremental cost-effectiveness ratio was calculated as the incremental cost of the exercise programme divided by the difference in quality-adjusted life years between both groups. Quality of life improved significantly at 1-year follow-up in both groups. Similarly, both groups significantly reduced total monthly costs over time. No significant difference was observed between groups. The incremental cost-effectiveness ratio was 79,270 euros. Adding an exercise programme after functional multidisciplinary rehabilitation compared with usual care does not offer significant long-term benefits in quality of life and direct and indirect costs.

To evaluate the prognostic effect of changes in physical function at different intervals over the prior year on subsequent outcomes after accounting for present function. Prospective longitudinal study. Greater New Haven, Connecticut, from March 1998 to January 2006. Community-living persons aged 71 and older who completed an 18-month comprehensive assessment (N=658). Disability in 13 activities of daily living, instrumental activities of daily living, and mobility activities was assessed at the 18-month comprehensive assessment and at 12, 6, and 3 months before 18 months. Time to death and long-term nursing home admission, defined as 3 months and longer, were ascertained for up to 5 years after 18 months. In the bivariate models, disability at 18 months and change in disability between 18 months and each of the 3 prior time-points (12, 6, 3 months) were significantly associated with time to death. The risk of death, for example, increased by 24% for each 1-point increase in 18-month disability score (on a scale from 0 to 13) and by 22% for each 1-point change in disability score between 18 months and prior 12 months (on a scale from -13 to 13). In a set of multivariable models with and without covariates, the associations were maintained for 18-month disability but not for change in disability between 18 months and each of the 3 prior time-points. The results were comparable for time to long-term nursing home admission except that 2 of the associations were not statistically significant. When evaluating risk of adverse outcomes, such as death and long-term nursing home admission, an assessment of change in physical function at different intervals over the prior year, although a strong bivariate predictor, did not provide useful prognostic information beyond that available from current level of function. © 2018, Copyright the Authors Journal compilation © 2018, The American Geriatrics Society.

To explore the clinical characters and histopathologic differences between patients with culture-positive and culture-negative prosthetic joint infection (PJI). Between January 2012 and July 2013, 66 PJI patients in accord with diagnostic criteria were enrolled. According to the results of preoperative aspiration and intraoperative cultures, the patients were divided into culture-negative group (CN group, n = 21) and culture-positive group (CP group, n = 45). There was no significant difference in gender, age, height, weight, and body mass index between 2 groups (P > 0.05). Preoperative C reactive protein (CRP), erythrocyte sedimentation rate (ESR), and prosthesis survival time were compared between 2 groups. Intraoperative frozen sections and paraffin sections were both performed to identify infections, and histological typing was performed according to Morawietz's methods. The preoperative CRP was (1.29 +/- 1.84) mg/dL in CN group and (5.08 +/- 9.57) mg/dL in CP group, showing significant difference (t = 2.094, P = 0.038). The preoperative ESR was (22.86 +/- 28.42) mm/1 h in CN group and (36.74 +/- 31.26) mm/1 h in CP group, showing significant difference (t = 7.761, P = 0.000). The median survival time of prosthesis was 72 months (range, 8-504 months) in CN group and 25 months (range, 15 days-300 months) in CP group, showing significant difference (U = 2.231, P = 0.026). Morawietz's histological typing results showed that 2 cases were rated as type I, 7 cases as type II, and 12 cases as type III in CN group; 6 cases were rated as type I, 25 cases as type II, 13 cases as type III, and 1 case as type IV in CP group. The positive culture rate was 68.18% (45/66), and pathogenic bacteria was dominated by Staphylococcus, accounting for 68.89%. The patients with culture-negative PJI have slow onset and mild inflammatory response, so comprehensive diagnosis should be made based on pathological detection, laboratory examination, and intraoperative cultures.

To retrospectively evaluate the added benefit of adding intraluminal radiofrequency ablation (RFA) to biliary metal stent placement for patients with malignant biliary obstruction (MBO). From November 2013 to December 2015, 89 patients with MBO who had undergone percutaneous intraluminal RFA and stent placement (RFA-stent group, n = 50) or stent placement only (stent group, n = 39) were included. Outcomes were compared according to the type of tumour: cholangiocarcinoma or non-cholangiocarcinoma. Primary and secondary stent patency (PSP, SSP) were significantly higher for the RFA-stent group than the stent group (PSP: 7.0 months vs. 5.0 months, p = 0.006; SSP: 10.0 months vs. 5.6 months, p < 0.001), with overall survival being comparable (5.0 months vs. 4.7 months, p = 0.068). In subgroup analysis, RFA-stent showed significant PSP benefits compared to stent alone in patients with cholangiocarcinoma (7.4 months vs. 4.3 months; p = 0.009), but with comparable outcomes in patients with non-cholangiocarcinoma (6.3 months vs. 5.2 months; p = 0.266). The SSP was improved in both subgroups (cholangiocarcinoma, 12.6 months vs. 5.0 months, p < 0.001; non-cholangiocarcinoma, 10.3 months vs. 5.5 months, p = 0.013). Technical success and clinical success were not significantly different between the two groups. The rate of complication was higher for the RFA-stent group, but tolerable when compared to the stent group. Although survival was comparable between the groups, RFA-stent confers therapeutic benefits to patients with MBO in terms of stent patency compared to stent placement alone, especially in those with cholangiocarcinoma.

We developed a novel hydrogel derived from sodium carboxymethylcellulose (CMC) in which phosphatidylethanolamine (PE) was introduced into the carboxyl groups of CMC to prevent perineural adhesions. This hydrogel has previously shown excellent anti-adhesive effects even after aggressive internal neurolysis in a rat model. Here, we confirmed the effects of the hydrogel on morphological and physiological recovery after nerve decompression. We prepared a rat model of chronic sciatic nerve compression using silicone tubing. Morphological and physiological recovery was confirmed at one, two, and three months after nerve decompression by assessing motor conduction velocity (MCV), the wet weight of the tibialis anterior muscle and morphometric evaluations of nerves. Electrophysiology showed significantly quicker recovery in the CMC-PE group than in the control group (24.0 ± 3.1 vs. 21.0± 2.1 m/s (p < 0.05) at one months and MCV continued to be significantly faster thereafter. Wet muscle weight at one month significantly differed between the CMC-PE (BW) and control groups (0.148 ± 0.020 vs. 0.108 ± 0.019%BW). The mean wet muscle weight was constantly higher in the CMC-PE group than in the control group throughout the experimental period. The axon area at one month was twice as large in the CMC-PE group compared with the control group (24.1 ± 17.3 vs. 12.3 ± 9 μm2) due to the higher ratio of axons with a larger diameter. Although the trend continued throughout the experimental period, the difference decreased after two months and was not statistically significant at three months. Although anti-adhesives can reduce adhesion after nerve injury, their effects on morphological and physiological recovery after surgical decompression of chronic entrapment neuropathy have not been investigated in detail. The present study showed that the new anti-adhesive CMC-PE gel can accelerate morphological and physiological recovery of nerves after decompression surgery.

Medical internship is known to be a time of high stress and long working hours, which increases the risk of depression and cardiovascular disease. Gender differences in medical interns' cardiovascular risk have not been reported previously. Thirty-eight medical interns (29 males) were repeatedly tested for depressive symptoms using the Hospital Anxiety and Depression Scale and 5-min spectral analysis of heart rate variability (HRV) at 3-month intervals during their internship. Among the male interns, the variance of the heart rate decreased at 6, 9, 12 months, and a reduced high frequency, which suggests reduced cardiac parasympathetic modulation, was found at 9 and 12 months into their internship. Increased depressive symptoms were also identified at 12 months in the male group. No significant differences in depression or any of the HRV indices were identified among the female interns during their internship. Copyright © 2013 Society for Psychophysiological Research.

Mother-infant interaction at 12 months in prenatally cocaine-exposed children.

2001-05-01

This study examined mother-infant interactions of 12-month-old African-American prenatally cocaine-exposed infants and their mothers. Videotaped observations were made during a free-play dyadic interaction, a brief separation, and a reunion period. Videotapes were coded for maternal and child behaviors during each phase of the procedure. Although there were few differences in interactive behaviors between prenatally cocaine-exposed and nonexposed children and their mothers, children who were prenatally exposed to cocaine ignored their mother's departure (odds ratio [OR] = 3.0, p < .05) during separation significantly more often than nonexposed subjects. In addition, mothers who abused cocaine engaged in significantly more verbal behavior (F(2,104) = 7.00, p < .001) with their children than mothers of nonexposed children. These findings indicate that women who used cocaine during pregnancy may not differ from nonusers in their interactions with their 12-month-old infants.

It was the aim of this study to analyze the influence of implant design and surface topography on the osseointegration of dental zirconium implants. Six different implant designs were tested in the study. Nine or 10 test implants were inserted in the frontal skull in each of 10 miniature pigs. Biopsies were harvested after 2 and 4 months and subjected to microradiography. No significant differences between titanium and zirconium were found regarding the microradiographically detected bone-implant contact (BIC). Cylindric zirconium implants showed a higher BIC at the 2-month follow-up than conic zirconium implants. Among zirconium implants, those with an intermediate Ra value showed a significantly higher BIC compared with low and high Ra implants 4 months after surgery. Regarding osseointegration, titanium and zirconium showed equal properties. Cylindric implant design and intermediate surface roughness seemed to enhance osseointegration.

The German diagnosis-related groups remuneration system (G-DRG) was implemented in 2004 and patient-related diagnoses and procedures lead to allocation to specific DRGs. This system includes several codes, such as case mix (CM), case mix index (CMI) and number of cases. Seasonal distribution of these codes as well as distribution of diagnoses and DRGs may lead to logistical consequences for clinical management. From 2004 to 2013 all the main diagnoses and DRGs for inpatients were recorded. Monthly and seasonal distributions were analyzed using ANOVA. The average monthly number of cases was 265 ± 25 cases, the average CM was 388.50 ± 51.75 and the average CMI was 1.46 ± 0.15 with no significant seasonal differences (p > 0.1). Concussion was the most frequently occurring main diagnosis (3739 cases) followed by fractures of the humeral head (699). Significant distribution differences could be shown for humeral head fractures in monthly (p = 0.018) and seasonal comparisons (p = 0.006) with a maximum in winter. Radius (p = 0.01) and ankle fractures (p ≤ 0.001) also occurred most frequently in winter. Non-bony lesions of the shoulder were significantly less in spring (p = 0.04). The DRGs showed no evidence of a monthly or seasonal clustering (p > 0.1). The significant clustering of injuries in specific months and seasons should lead to logistic consequences (e.g. operating room slots, availability of nursing and anesthesia staff). For a needs assessment the analysis of main diagnoses is more appropriate than DRGs.

A two-institution retrospective study was undertaken to determine whether two different prepalatoplasty protocols quantitatively affect maxillary arch morphology in infants with complete unilateral cleft lip and palate (UCLP). Serial maxillary dental casts, obtained at regular intervals through the first 18 months of life from preintervention until palatoplasty were evaluated quantitatively using computer-assisted three-dimensional digitization and analysis for three populations: institution 1 (protocol 1), institution 2 (protocol 2), and unaffected individuals (neither cleft nor treatment). Sequential UCLP patients from institution 1 were matched for age and initial alveolar cleft width, sex and cleft side having been demonstrated to be nonsignificant, with UCLP patients from institution 2 and to unaffected individuals for age for the analysis. Both treatment institutions are well-established regional interdisciplinary cleft centers. Institution 1 is located in a tertiary, academic children's hospital in a metropolis within a primarily agrarian region of the Midwest; institution 2 is a freestanding private clinic located in a small city within a primarily agrarian region of an eastern state; the unaffected population is a historic archive acquired in the 1930s. Data acquisition (model digitization) and computer processing were performed at institution 1. Eighty-five casts of 28 infants from institution 1, 106 casts of 31 infants from institution 2, and 68 casts of 29 unaffected infants were analyzed. All infants had alginate impressions taken prior to intervention and at several additional 6-month intervals after that, consistent with each institution's treatment protocol. At institution 1, patients with UCLP underwent lip adhesion and placement of a passive alveolar molding plate at 7 weeks of age, definitive cheiloplasty at 7 months of age, and one-stage palatoplasty at 14 months of age. At institution 2, patients with UCLP underwent definitive cheiloplasty at 3 months of age, had no maxillary orthopedics, and had vomer flap hard palate repair at 12 months of age and soft palate repair at 18 months of age. The outcome measures included directly digitized (cleft segment and hemialveolar ridge lengths) and derived (alveolar base width, alveolar cleft gap, maxillary frenum-alveolar base perpendicular angle, and rates of change over time of digitized cleft segment and hemialveolar ridge lengths) features. The data were assessed by comparing simple linear regression lines and an unpaired, two-tailed t test. Prior to initiating therapy, there were no statistically significant differences between the two populations with clefts. However, both populations with clefts differed significantly from unaffected individuals (p < .001), with increased maxillary base widths and larger perpendicular/frenum angles. At the time of palatoplasty, the two populations with clefts had statistically significant differences between them in the maxillary base width (p < .01) and the cleft gap distance (p < .05). The base width of institution 1 did not differ significantly from that of widths of unaffected children, and that of institution 2 was significantly less, although the latter had already received first-stage palate repair. Alveolar segment growth rates were similar for the greater and lesser segments, respectively, and the left side hemialveolus of both groups. The growth rate for the noncleft side hemialveolus of institution 2 exceeded (p < .05) that of both institution 1 and unaffected patients. Two different regimens for the initial management of UCLP can significantly affect maxillary alveolar arch growth with respect to the treatment used and in comparison with unaffected controls.

The objective of the Aliskiren Trial on Acute Heart Failure Outcomes (ASTRONAUT) was to determine whether aliskiren, a direct renin inhibitor, would improve post-discharge outcomes in patients with hospitalization for heart failure (HHF) with reduced ejection fraction. Pre-specified subgroup analyses suggested potential heterogeneity in post-discharge outcomes with aliskiren in patients with and without baseline diabetes mellitus (DM). ASTRONAUT included 953 patients without DM (aliskiren 489; placebo 464) and 662 patients with DM (aliskiren 319; placebo 343) (as reported by study investigators). Study endpoints included the first occurrence of cardiovascular death or HHF within 6 and 12 months, all-cause death within 6 and 12 months, and change from baseline in N-terminal pro-B-type natriuretic peptide (NT-proBNP) at 1, 6, and 12 months. Data regarding risk of hyperkalaemia, renal impairment, and hypotension, and changes in additional serum biomarkers were collected. The effect of aliskiren on cardiovascular death or HHF within 6 months (primary endpoint) did not significantly differ by baseline DM status (P = 0.08 for interaction), but reached statistical significance at 12 months (non-DM: HR: 0.80, 95% CI: 0.64-0.99; DM: HR: 1.16, 95% CI: 0.91-1.47; P = 0.03 for interaction). Risk of 12-month all-cause death with aliskiren significantly differed by the presence of baseline DM (non-DM: HR: 0.69, 95% CI: 0.50-0.94; DM: HR: 1.64, 95% CI: 1.15-2.33; P < 0.01 for interaction). Among non-diabetics, aliskiren significantly reduced NT-proBNP through 6 months and plasma troponin I and aldosterone through 12 months, as compared to placebo. Among diabetic patients, aliskiren reduced plasma troponin I and aldosterone relative to placebo through 1 month only. There was a trend towards differing risk of post-baseline potassium ≥6 mmol/L with aliskiren by underlying DM status (non-DM: HR: 1.17, 95% CI: 0.71-1.93; DM: HR: 2.39, 95% CI: 1.30-4.42; P = 0.07 for interaction). This pre-specified subgroup analysis from the ASTRONAUT trial generates the hypothesis that the addition of aliskiren to standard HHF therapy in non-diabetic patients is generally well-tolerated and improves post-discharge outcomes and biomarker profiles. In contrast, diabetic patients receiving aliskiren appear to have worse post-discharge outcomes. Future prospective investigations are needed to confirm potential benefits of renin inhibition in a large cohort of HHF patients without DM.

Soil respiration rates were measured monthly (from April 2007 to March 2008) under four adjacent coniferous plantation sites [Oriental spruce (Picea orientalis L.), Austrian pine (Pinus nigra Arnold), Turkish fir (Abies bornmulleriana L.), and Scots pine (Pinus sylvestris L.)] and adjacent natural Sessile oak forest (Quercus petraea L.) in Belgrad Forest-Istanbul/Turkey. Also, soil moisture, soil temperature, and fine root biomass were determined to identify the underlying environmental variables among sites which are most likely causing differences in soil respiration. Mean annual soil moisture was determined to be between 6.3 % and 8.1 %, and mean annual temperature ranged from 13.0°C to 14.2°C under all species. Mean annual fine root biomass changed between 368.09 g/m(2) and 883.71 g/m(2) indicating significant differences among species. Except May 2007, monthly soil respiration rates show significantly difference among species. However, focusing on tree species, differences of mean annual respiration rates did not differ significantly. Mean annual soil respiration ranged from 0.56 to 1.09 g C/m(2)/day. The highest rates of soil respiration reached on autumn months and the lowest rates were determined on summer season. Soil temperature, soil moisture, and fine root biomass explain mean annual soil respiration rates at the highest under Austrian pine (R (2) = 0.562) and the lowest (R (2) = 0.223) under Turkish fir.

To evaluate mapping characteristics of children with cochlear implants who are enrolled in the Childhood Development After Cochlear Implantation (CDACI) multicenter study. Longitudinal evaluation during 24 months of speech processor maps of children with cochlear implants prospectively enrolled in the study. Six tertiary referral centers. One hundred eighty-eight children enrolled in the CDACI study who were 5 years old or younger at the time of enrollment. Of these children, 184 received unilateral implants, and 4 received simultaneous bilateral implants. Children attended regular mapping sessions at their implant clinic as part of the study protocol. Maps were examined for each subject at 4 different time intervals: at device activation and 6, 12, and 24 months postactivation. Mean C/M levels (in charge per phase) were compared for 4 different time intervals, for 3 different devices, for 6 different implant centers, and for children with normal and abnormal cochleae. All 3 types of implant devices demonstrate significant increases in C/M levels between device activation and the 24-month appointment. Significant differences in mean C/M levels were noted between devices. Children with cochlear anomalies demonstrate significantly greater C/M levels than children with normal cochleae. The CDACI study has enabled us to evaluate the mapping characteristics of pediatric patients who use 3 different devices and were implanted at a variety of implant centers. Analysis of such data enables us to better understand the mapping characteristics of children with cochlear implants.

This study evaluated the efficacy of a child-focused versus context-focused intervention in improving performance of functional tasks and mobility in young children with cerebral palsy. A randomized controlled trial cluster research design enrolled 128 children (49 females, 79 males; age range 12 mo to 5 y 11 mo; mean age 3 y 6 mo, SD -1 y 5 mo) who were diagnosed with cerebral palsy. Children across levels I to V on the Gross Motor Classification System (GMFCS) were included in the study. Children were excluded if there were planned surgical or medication changes during the intervention period. Therapists from 19 children's rehabilitation centers were block randomized (by occupational therapist or physical therapist) to a treatment arm. Children from consenting families followed their therapists into their assigned group. Children received child-focused (n=71) or context-focused intervention (n=57) over 6 months, returning to their regular therapy schedule and approach between 6 and 9 months. The primary outcome measure was the Pediatric Evaluation of Disability Inventory (PEDI). Secondary outcome measures included the Gross Motor Function Measure (GMFM-66), range of motion of hip abduction, popliteal angle and ankle dorsiflexion, the Assessment of Preschool Children's Participation (APCP), and the Family Empowerment Scale (FES). Outcome evaluators were masked to group assignment and completed assessments at baseline, 6 months, and 9 months. Ten children did not complete the full intervention, six in the child group and four in context group. GMFCS levels for children in the study were level I (n=37), level II (n=23), level III (n=21), level IV (n=21), and level V (n=26). There were no significant differences at baseline between the treatment groups for GMFCS level, parental education, or parental income. For the PEDI, there was no significant difference between the treatment groups, except for a small effect (p<0.03) on the Caregiver Assistance Mobility subscale between baseline and 9 months. The mean scores of both groups changed significantly on the Functional Skills Scales (p<0.001) and Caregiver Assistance Scales (p<0.02) of the PEDI after the 6-month intervention. There was no additional statistically significant change on the PEDI during the follow-up period from 6 to 9 months. A subgroup effect was found for age (p<0.001), with children younger than 3 years changing significantly more than older children. GMFCS level at baseline did not influence the amount of change on the PEDI scales. There were no significant differences between the treatment groups on the GMFM, range of motion measures, APCP or FES assessments. For the GMFM, there was a significant change over time from baseline to 6 months (p<0.001) and no significant change between 6 and 9 months. There was no adverse side effect as range of motion did not decrease in either group. Hip abduction increased significantly (p<0.01) at the 9-month assessment for both groups. For the APCP, significant changes for both treatment groups were found between baseline and 6 months for play intensity (p<0.04), physical activity intensity and diversity (p<0.001), and total score intensity (p<0.01). This study shows that child- or context-focused therapy approaches are equally effective and that frequency of intervention may be a critical component of successful intervention. Further evaluation is required to identify the various 'dose-response' relations of amount of treatment and changes in functional abilities. © The Authors.

INTRODUCTION Physiotherapy is an important part of rehabilitation following arthroplasty, but the impact of preoperative physiotherapy on functional outcomes is still being studied. This randomised controlled trial evaluated the effect of preoperative physiotherapy on the short-term functional outcomes of primary total knee arthroplasty (TKA). METHODS 50 patients with primary knee osteoarthritis who underwent unilateral primary TKA were randomised into two groups: the physiotherapy group (n = 24), whose patients performed physical exercises for six weeks immediately prior to surgery, and the nonphysiotherapy group (n = 26). All patients went through a similar physiotherapy regime in the postoperative rehabilitation period. Functional outcome assessment using the algofunctional Knee Injury and Osteoarthritis Outcome Score (KOOS) scale and range of motion (ROM) evaluation was performed preoperatively, and postoperatively at six weeks and three months. RESULTS Both groups showed a significant difference in all algofunctional KOOS subscales (p < 0.001). The mean score difference at six weeks and three months was not significant in the sports and recreational activities subscale for both groups (p > 0.05). Significant differences were observed in the time-versus-treatment analysis between groups for the symptoms (p = 0.003) and activities of daily living (p = 0.025) subscales. No significant difference in ROM was found when comparing preoperative measurements and those at three months following surgery, as well as in time-versus-treatment analysis (p = 0.928). CONCLUSION Six-week preoperative physiotherapy showed no significant impact on short-term functional outcomes (KOOS subscales) and ROM of the knee following primary TKA. PMID:26996450

A retrospective national claims database analysis evaluated total and wound-related costs (eg, hospital readmission rates) for patients with chronic wounds treated with negative pressure wound therapy (NPWT), comparing NPWT-V (V.A.C. Therapy, KCI, an Acelity company, San Antonio, TX) and NPWT-O (other non-KCI models of NPWT, the brands of which were not known to the researchers). Patients with ≥ 1 NPWT claim from January 2009-June 2012 in outpatient settings in the United States were included, if they had continuous medical and pharmacy benefits for 12 months before the initial index date of their NPWT claim and at least 3 months post index. Mean total health care costs were assessed at 3 months and 12 months; wound-related hospital readmission rates were assessed at 3 months and 6 months. Cost differences between cohorts were analyzed by t test and readmission rates were analyzed by chi-square test. At 3 months, the cohort of NPWT-V patients was significantly younger (59.2 vs 63.6 years, P < 0.01). The same patients were followed at 3, 6, and 12 months, although some fell out as time progressed. At the 3-month assessment, mean comorbidity scores did not differ between the NPWT-V group and the NPWT-O groups (3.38 vs 3.66). Total costs were lower for NPWT-V vs NPWT-O at 3 months ($35,498 vs $39,722, respectively; P = 0.08) and 12 months ($80,768 vs $111,212; P = 0.03). Significantly lower inpatient (P = 0.01), emergency room (P < 0.01), and home (P = 0.05) costs, despite higher (P = 0.04) NPWT costs, accounted for lower 12-month NPWT-V total costs. Wound-related readmission rates were significantly lower for NPWT-V at 3 months (5% vs 8%; P ≤ 0.01) and 6 months (6% vs 11%; P ≤ 0.01). For all wound types, NPWT-O patients had a 17-fold higher rate of switching to alternate NPWT models compared with NPWT-V patients. In this retrospective analysis, NPWT-V patients had lower total costs, lower wound-related costs, and lower hospital readmission rates than NPWT-O patients at all time points assessed.

A cross-sectional study was carried out at Shifa International Hospital Islamabad over a period of 6 months, to determine the frequency and compare the different lifestyle modifications among patients with Gastroesophageal Reflux Disease (GERD) of different monthly income groups. Two hundred patients of GERD were enrolled in the study and divided into two groups based on monthly income less than and more than Rs. 30,000 respectively. Data was analyzed using SPSS 21. Descriptive statistics were calculated. Chi-square test was applied keeping p-value <0.05. Mean age was 40±13 years, 82 (41%) males and 118 (59%) females. Walking was undertaken by 32% after meals and 87.5% consumed tea. Significant difference was seen between income groups and higher intake of fried and spicy foods respectively. Thus, effort needs to be made in creating awareness and counseling patients to practice lifestyle modifications to reduce GERD symptoms and stop sole reliance on medications.

This study assessed the relationship between self-control and credit-card use with a convenience sample of 165 traditional-age college students of whom 69 (42%) were women. Students' self-control was measured on Grasmick, et al.'s Self-control Scale, which has six subscales, one of which is Impulsivity. Comparisons were made between those students who paid their cards off each month, called convenience users, and those who carried a monthly balance forward on scores on total self-control and impulsivity, and number of credit cards possessed. A significant difference in self-control scores was found between these two groups and also for mean impulsivity scores. Significantly fewer credit cards were possessed by students who paid their cards off each month than by those who carried a monthly balance.

The effects of red palm oils known as Naturally Vitamin Rich Oil (NVRO) on the lipid stability of chicken nuggets were determined. Lipid oxidation was analyzed during frozen storage (-18 °C) for up to 4 months. Thiobarbituric acid (TBA) values and peroxide value (PV) for all samples chicken nuggets increased throughout 3 months of frozen storage and then start to decrease thereafter. Chicken nuggets formulated with NVRO, NVRO-100 and NVRO-50 showed lower TBA values and PV compared to the samples prepared with chicken fat. However, among NVRO, there were not significantly different for most of the months. It was concluded that the utilization of red palm oils in chicken nuggets significantly reduced the oxidation of lipid, which was indicated by the PV throughout 4 months of frozen storage.

The correlation between radiation dose and loco-regional control (LRC) was evaluated in patients with stage II-III esophageal cancer treated with definitive concurrent chemoradiotherapy (CRT). Medical records of 236 stage II-III esophageal cancer patients treated with definitive CRT at Yonsei Cancer Center between 1994 and 2013 were retrospectively reviewed. Among these, 120 received a radiation dose of < 60 Gy (standard-dose group), while 116 received ≥ 60 Gy (high-dose group). The median doses of radiation in the standard- and high-dose groups were 50.4 and 63 Gy, respectively. Concurrent 5-fluorouracil/cisplatin chemotherapy was administered to most patients. There were no differences in patient characteristics between the two groups except for high Karnofsky performance status and lower-thoracic lesions being more prevalent in the standard-dose group. The median progression-free survival (PFS) and overall survival (OS) times were 13.2 months and 26.2 months, respectively. Patients in the high-dose group had significantly better 2-year LRC (69.1% vs. 50.3%, p=0.002), median PFS (16.7 months vs. 11.7 months, p=0.029), and median OS (35.1 months vs. 22.3 months, p=0.043). Additionally, LRC exhibited a dose-response relationship and the complete response rate was significantly higher in the high-dose group (p=0.006). There were no significant differences in treatment-related toxicities between the groups. A higher radiation dose (> 60 Gy) is associated with increased LRC, PFS, and OS in patients with stage II-III esophageal cancer treated with definitive CRT.

Purpose: To explore whether gender and race influence survival in non-small-cell lung cancer (NSCLC) in patients with brain metastases, using our large single-institution brain tumor database and the Radiation Therapy Oncology Group recursive partitioning analysis (RPA) brain metastases classification. Methods and materials: A retrospective review of a single-institution brain metastasis database for the interval January 1982 to September 2004 yielded 835 NSCLC patients with brain metastases for analysis. Patient subsets based on combinations of gender, race, and RPA class were then analyzed for survival differences. Results: Median follow-up was 5.4 months (range, 0-122.9 months). There were 485 male patients (M)more » (58.4%) and 346 female patients (F) (41.6%). Of the 828 evaluable patients (99%), 143 (17%) were black/African American (B) and 685 (83%) were white/Caucasian (W). Median survival time (MST) from time of brain metastasis diagnosis for all patients was 5.8 months. Median survival time by gender (F vs. M) and race (W vs. B) was 6.3 months vs. 5.5 months (p = 0.013) and 6.0 months vs. 5.2 months (p = 0.08), respectively. For patients stratified by RPA class, gender, and race, MST significantly favored BFs over BMs in Class II: 11.2 months vs. 4.6 months (p = 0.021). On multivariable analysis, significant variables were gender (p = 0.041, relative risk [RR] 0.83) and RPA class (p < 0.0001, RR 0.28 for I vs. III; p < 0.0001, RR 0.51 for II vs. III) but not race. Conclusions: Gender significantly influences NSCLC brain metastasis survival. Race trended to significance in overall survival but was not significant on multivariable analysis. Multivariable analysis identified gender and RPA classification as significant variables with respect to survival.« less

In an ongoing prospective study of 14 recreational athletes (12 males and 2 females, mean age 44.2 +/- 7.1 years) with unilateral chronic Achilles tendinosis, we investigated the effect of treatment with heavy-loaded eccentric calf-muscle training. Pain during activity (recorded on a VAS scale) and isokinetic concentric and eccentric calf-muscle strength (peak torque at 90 degrees /second and 225 degrees /second) on the injured and noninjured side were evaluated. In this group of patients, we examined areal bone mineral density (BMD) of the calcaneus after 9 months (range 6-14 months) of training. BMD of the injured side (subjected to heavy-loaded eccentric training) was compared with BMD of the noninjured side. Before onset of heavy-loaded eccentric training, all patients had Achilles tendon pain which prohibited running activity, and significantly lower concentric and eccentric plantar flexion peak torque on the injured compared with the noninjured side. The training program consisted of 12 weeks of daily, heavy-loaded, eccentric calf-muscle training; thereafter the training was continued for 2-3 days/week. The clinical results were excellent-all 14 patients were back at their preinjury level with full running activity at the 3 month follow-up. The concentric and eccentric plantar flexion peak torque had increased significantly and did not significantly differ from the noninjured side at the 3 and 9 month follow-up. There were no significant side-to-side differences in BMD of the calcaneus. There was no significant relationship between BMD of the calcaneus and calf-muscle strength. As a comparison group, we used 10 recreational athletes (5 males and 5 females) mean age 40.9 years (range 26-55 years), who were selected for surgical treatment of chronic Achilles tendinosis localized at the 2-6 cm level. Their duration of symptoms and severity of disease were the same as in the experimental group. There were no significant side-to-side differences in BMD of the calcaneus preoperatively, but 12 months postoperatively BMD of the calcaneus was 16.4% lower at the injured side compared with the noninjured side. Heavy-loaded eccentric calf-muscle training resulted in a fast recovery in all patients, equaled the side-to-side differences in muscle strength, and was not associated with side-to-side differences in BMD of the calcaneus. In this group of middle-aged recreational athletes, BMD of the calcaneus was not related to calf-muscle strength.

We designed a randomized, double blinded, 3-months controlled prospective clinical study to investigate effects of oral uridine on the ocular surface in dry eye patients. Twenty-seven patients who diagnosed as dry eye with lower than 5 mm of wetting in the Schirmer strip, with corneal epithelial erosion and who completely followed-up till 3 months were enrolled. Corneal-conjunctival fluorescein staining, non-anesthetic Schirmer test, impression cytology, and Ocular Surface Disease Index (OSDI) were evaluated in the experimental and placebo groups at the baseline, 1 and 3 months after start of medication in a double blinded manner. Fluorescein stain score of the cornea was markedly decreased in oral uridine group compared to the placebo group at 3 months after medication (P=0.032, Mann-Whitney U test). The Schirmer wetting score for the oral uridine group was significantly increased (P=0.001, Wilcoxon signed rank test) at 3 months and its difference between two groups was statistically significant (P=0.030, Mann-Whitney U test). OSDI scores were significantly decreased at 1 and 3 months in treatment group. Oral uridine is effective in treatment of dry eyes.

Background Large numbers of women who participate in cervical screening require follow-up for minor cytological abnormalities. Little is known about the psychological consequences of alternative management policies for these women. We compared, over 30-months, psychosocial outcomes of two policies: cytological surveillance (repeat cervical cytology tests in primary care) and a hospital-based colposcopy examination. Methods Women attending for a routine cytology test within the UK NHS Cervical Screening Programmes were eligible to participate. 3399 women, aged 20–59 years, with low-grade abnormal cytology, were randomised to cytological surveillance (six-monthly tests; n = 1703) or initial colposcopy with biopsies and/or subsequent treatment based on colposcopic and histological findings (n = 1696). At 12, 18, 24 and 30-months post-recruitment, women completed the Hospital Anxiety and Depression Scale (HADS). A subgroup (n = 2354) completed the Impact of Event Scale (IES) six weeks after the colposcopy episode or first surveillance cytology test. Primary outcomes were percentages over the entire follow-up period of significant depression (≥8) and significant anxiety (≥11; “30-month percentages”). Secondary outcomes were point prevalences of significant depression, significant anxiety and procedure-related distress (≥9). Outcomes were compared between arms by calculating fully-adjusted odds ratios (ORs) for initial colposcopy versus cytological surveillance. Results There was no significant difference in 30-month percentages of significant depression (OR = 0.99, 95% CI 0.80–1.21) or anxiety (OR = 0.97, 95% CI 0.81–1.16) between arms. At the six-week assessment, anxiety and distress, but not depression, were significantly less common in the initial colposcopy arm (anxiety: 7.9% vs 13.4%; OR = 0.55, 95% CI 0.38–0.81; distress: 30.6% vs 39.3%, OR = 0.67 95% CI 0.54–0.84). Neither anxiety nor depression differed between arms at subsequent time-points. Conclusions There was no difference in the longer-term psychosocial impact of management policies based on cytological surveillance or initial colposcopy. Policy-makers, clinicians, and women themselves can be reassured that neither management policy has a significantly greater psychosocial cost.

Placental redistribution has been shown to improve haematological outcomes in the immediate neonatal period and early infancy. This study compared the effects of delayed cord clamping (DCC) and umbilical cord milking (UCM) on haematological and growth parameters at 12 months of age. This was a follow-up study of a randomised control trial, conducted in a tertiary care paediatric centre from August 2013 to August 2014. We studied 200 apparently healthy Indian infants randomised at birth to receive DCC for 60-90 seconds or UCM. The outcome measures were iron status and physical growth parameters at 12 months. Of the 200 babies, 161 completed the follow-up and baseline characteristics were comparable in both groups. The mean haemoglobin in the DCC group (102.2 (17.2) g/L and serum ferritin 16.44 (2.77) μg/L) showed no significant differences to the UCM group (98.6 (17.1) g/L and 18.2 (2.8) μg/L) at one year. In addition, there were no significant differences in weight, height and mid-upper arm circumference in the two groups. Term-born Indian infants who had DCC at 60-90 seconds or UCM showed no significant differences in ferritin and haemoglobin levels and growth parameters at 12 months of age. ©2016 Foundation Acta Paediatrica.

To assess the effects of a communication skills program on professional practitioners' performance and self-confidence in clinical interviewing. Twenty-five health professionals took 3 months of basic communication skills followed by 3 months of advanced communication skills. An additional quarter dealt with self-awareness and communication in special situations. Participants' performances were evaluated in clinical interviews with standardized patients before, during and after the program by external observers and standardized patients, using standardized instruments. Participants assessed their own confidence in their communication skills before and after the program. Data were analysed using GLM repeated-measures procedures in SPSS. Basic communication skills and self-confidence improved throughout the 6 months; competencies declined but self-confidence continued to increase 4 months later. Compared with taking no course, differences were statistically significant after the 6 months (external observers only) and 4 months later (external observers and participants). The program effectively improved communication skills, although significantly only when assessed by external observers. Four months later, effects were significant in communication skills (external observers), despite the decline and in self-confidence. While periodical enrollment in programs for the practice of communication skills may help maintain performance, more knowledge on communication and self-awareness may enhance self-confidence.

Objectives: To investigate the effects on muscle performance after one-year cessation of 18-month low-magnitude high-frequency vibration (LMHFV) intervention in the untrained community elderly. Methods: This is a case-control study with 59 community elderly women (25 control without any treatment; 34 received 18-month LMHFV but discontinued for 1 year from our previous clinical study). Muscle strength, balancing ability, occurrence of fall/fracture, quality of life (QoL) were assessed 1-year after cessation of intervention. The 30-month results were compared with baseline and 18-month treatment endpoint data between groups. Results: At 30 months (i.e. one year post-intervention), the muscle strengths of dominant and non-dominant legs relative to baseline in treatment group were significantly better than those of control. In balancing ability test, reaction time, movement velocity and maximum excursion of treatment group (relative to baseline) remained significantly better than the control group. The muscle strength, balancing ability and quality of life at 30 months relative to 18 months did not show significant differences between the two groups. Conclusion: The benefits of LMHFV for balancing ability, muscle strength and risk of falling in elderly were retained 1 year after cessation of LMHFV. PMID:26944817

This study was designed to find whether long-term survivors (LTSs) exhibit molecular genetic differences compared with short-term survivors (STSs) in patients with GBM. Tumors from 12 patients initially diagnosed with GBM and survived longer than 36 months (LTSs) were compared with 30 patients with GBM and STSs (survival <18 months) for detecting of MGMT promoter methylation, 1p/19q LOH and IDH1 mutation. IDH1 mutation and MGMT promoter methylation were significantly more frequent in the LTSs group (P = 0.039 and 0.017, respectively). The incidence of 1p/19q co-deletion was not significantly different (P = 1.0). IDH1 mutation and MGMT promoter methylation might be independent, significant, and favorable factors for LTSs with GBM.

Generalized joint laxity has been proposed as a significant risk factor for failure after arthroscopic anterior shoulder stabilization. The purpose of this study was to prospectively measure joint mobility in patients undergoing arthroscopic anterior shoulder stabilization and to determine whether hypermobility is a risk factor for worse outcomes compared with patients having normal joint mobility. Patients with anterior shoulder instability were prospectively enrolled. Generalized joint hypermobility was measured using the Beighton Hypermobility Score and the Rowe, UCLA, SANE, SST, and WOSI scores were administered and reported as patient outcomes preoperatively and following arthroscopic anterior shoulder stabilization at 6 weeks, 6 months, 12 months, and 24 months postoperatively. Patients were stratified into two groups based on their Beighton Hypermobility Score, with scores ≥ 4/9 indicative of joint hypermobility. Sixteen patients with joint hypermobility (JH) and 18 non-hypermobile patients (NJH) were enrolled. At baseline, there were no significant differences in demographic characteristics or baseline patient-reported outcomes. Significantly more patients in the NJH group had SLAP tears (n = 10) compared to the JH group (n = 2) (p = .013). At all follow-up times, there were no significant differences between the NJH and JH groups with regard to patient-reported outcome scores (p > .05). In the JH group, 17% of patients reported recurrent instability at two years postoperatively compared to 25% of patients in the NJH group. There was no significant difference in failure rate (p = .67). There was no significant difference in patient-reported outcomes or recurrent instability in patients with versus without joint hypermobility undergoing arthroscopic anterior shoulder stabilization.

This study aimed to establish validity and reliability of the Filipino Reflux Symptom Index (FRSI) and to test it among patients with laryngopharyngeal reflux (LPR) before and after 6 months' trial of rabeprazole. A case-control study was carried out. There were 35 LPR patients and 30 controls who were twice-administered the FRSI and Filipino Voice Handicap Index (FVHI) for test-retest reliability, and videostroboscopy was performed to obtain baseline reflux finding scores (RFSs). Patients took rabeprazole 20 mg twice daily for 6 months. The FRSI and FVHI were readministered a third time, repeat videostroboscopy was performed, and repeat RFS was obtained. Reliability, validity, and internal consistency were computed. A total of 58 participants, 29 patients and controls each, aged 22-65 years completed the study. FVHI 2:1 and FRSI 2:1 significantly correlated with no significant differences between FRSI 2:1. FRSI had good item-total correlations indicating psychometrically sound items. There were significant differences between patients and controls for FRSI scores and mean scores. FRSI 3 scores were significantly lower than FRSI 1 scores, suggesting symptoms improved after treatment. There were no significant differences between RFS 2 and 1. Significant differences between FRSI 3 and 1, but not between FVHI 3 and 1, suggest the FRSI was more sensitive to changes in reflux after 6 months' intervention than the FVHI. The FRSI is a valid and reliable tool for assessing LPR symptoms and may be used for primary care screening among Filipinos. Initial response to a 2-week empirical proton pump inhibitor trial may support an impression of LPR; non-response warrants specialist referral for further investigation.

The purpose of this study was to compare resistance exercise training (RT) to aerobic exercise training (AE) on the clinical risk factors for metabolic syndrome (MetSyn) in physically inactive overweight males (age 27-48 years). Subjects with at least one risk factor for MetSyn performed RT (n = 13, age 35.1 ± 4.7 years, BMI 31.2 ± 2.7 kg/m(2)) or AE (n = 9, age 37.6 ± 4.9 years, BMI, 31.2 ± 3.2 kg/m(2)) for 6 months. Training frequency and exercise session duration were equal and by 3 months the subjects exercised 4 day/week for 45 min/session. Blood lipids and glucose, waist circumference, and mean arterial blood pressure (MAP) were measured at 0, 3, and 6 months. A MetSyn z score was calculated for each subject from triglycerides, HDL cholesterol, fasting glucose, waist circumference, and MAP. Statistical significance was set at p ≤ 0.05. No significant differences existed between RT and AE groups at 0 month. AE showed a significant reduction in MetSyn z score from 0 (0.91 ± 3.57) to 6 months (-1.35 ± 2.95), while RT approached significance (p = 0.07) from 0 (0.09 ± 2.62) to 6 months (-1.30 ± 2.22). Triglycerides (mmol/L) significantly decreased in AE from 0 (1.93 ± 0.90) to 6 months (1.41 ± 0.70). Waist circumference (cm) significantly decreased in AE from 0 (106.8 ± 7.3) to 6 months (101.2 ± 6.5), and in RT from 0 (108.4 ± 9.0) to 6 months (105.7 ± 7.0). MAP (mmHg) decreased in RT from 0 (93.8 ± 5.8) to 6 months (87.5 ± 6.1) and in AE from 0 (97.6 ± 7.0) to 6 months (91.3 ± 6.8). With equal training frequency and exercise session duration, both RT and AE training, when paired with energy restriction improve the clinical risk factor profile for MetSyn.

Obesity is associated with numerous health problems, particularly metabolic and cardiovascular complications. This study aimed to assess the effects that, nine months of pharmacological intervention with orlistat or sibutramine, on obese Malaysians' body weight and compositions, metabolic profiles and inflammatory marker. Seventy-six obese subjects were randomly placed into two groups. The first group received three daily 120 mg dosages of orlistat for nine months (n=39), and the second group received a once daily 10 or 15 mg dosage of sibutramine for nine months (n=37). Baseline measurements for weight, body mass index (BMI), waist circumference (WC), body fat percentage (BF), visceral fat (VF), adiponectin, fasting plasma glucose (FPG), fasting insulin, pancreatic B cell secretory capacity (HOMA%B), insulin sensitivity (HOMA%S), insulin resistance (HOMA-IR) and serum high sensitivity C-reactive protein (hs-CRP) were performed and repeated during the sixth and ninth months of treatment. Twenty-four subjects completed the trial in both groups. For both groups, weight, BMI, WC, BF, VF, HOMA-IR and hs-CRP were significantly lower at the end of the nine month intervention. However, there were no significant differences between the two groups for these parameters with nine months treatment. There was a significant decrease in FPG in orlistat group; while fasting insulin and HOMA%B reduced in sibutramine group. For both groups, there were also significant increases in adiponectin levels and HOMA%S at the end of the nine month intervention. Nine months of treatment with orlistat and sibutramine not only reduced weight but also significantly improved BMI, WC, BF, VF, FPG, adiponectin, fasting insulin, HOMA%B, HOMA%S, HOMA-IR and hs-CRP. These improvements could prove useful in the reduction of metabolic and cardiovascular risks in obese subjects.

To study the effects of postnatal growth retardation on early neurodevelopment in premature infants with intrauterine growth retardation (IUGR). A retrospective analysis was performed on the clinical data of 171 premature infants who were born between May 2008 and May 2012 and were followed up until a corrected gestational age of 6 months. These infants were classified into two groups: IUGR group (n=40) and appropriate for gestational age (AGA) group (n=131). The growth retardation rates at the corrected gestational ages of 40 weeks, 3 months, and 6 months, as well as the neurodevelopmental outcome (evaluated by Gesell Developmental Scale) at corrected gestational ages of 3 and 6 months, were compared between the two groups. The growth retardation rate in the IUGR group was significantly higher than in the AGA group at the corrected gestational ages of 40 weeks, 3 months, and 6 months. All five developmental quotients evaluated by Gesell Developmental Scale (gross motor, fine motor, language, adaptability and individuality) in the IUGR group were significantly lower than in the AGA group at the corrected gestational ages of 3 months. At the corrected gestational age of 6 months, the developmental quotients of fine motor and language in the IUGR group were significantly lower than in the AGA group, however, there were no significant differences in the developmental quotients of gross motor, adaptability and individuality between the two groups. All five developmental quotients in IUGR infants with catch-up lag in weight were significantly lower than in IUGR and AGA infants who had caught up well. Growth retardation at early postnatal stages may adversely affect the early neurodevelopment in infants with IUGR.

Glycemic control often deteriorates during adolescence and the transition to young adulthood for patients with type 1 diabetes. The inability to manage type 1 diabetes effectively during these years is associated with poor glycemic control and complications from diabetes in adult life. To determine the effect of daily financial incentives on glucose monitoring adherence and glycemic control in adolescents and young adults with type 1 diabetes. The Behavioral Economic Incentives to Improve Glycemic Control Among Adolescents and Young Adults With Type 1 Diabetes (BE IN CONTROL) study was an investigator-blinded, 6-month, 2-arm randomized clinical trial conducted between January 22 and November 2, 2016, with 3-month intervention and follow-up periods. Ninety participants (aged 14-20) with suboptimally controlled type 1 diabetes (hemoglobin A1c [HbA1c] >8.0%) were recruited from the Diabetes Center for Children at the Children's Hospital of Philadelphia. All participants were given daily blood glucose monitoring goals of 4 or more checks per day with 1 or more level within the goal range (70-180 mg/dL) collected with a wireless glucometer. The 3-month intervention consisted of a $60 monthly incentive in a virtual account, from which $2 was subtracted for every day of nonadherence to the monitoring goals. During a 3-month follow-up period, the intervention was discontinued. The primary outcome was change in HbA1c levels at 3 months. Secondary outcomes included adherence to glucose monitoring and change in HbA1c levels at 6 months. All analyses were by intention to treat. Of the 181 participants screened, 90 (52 [57.8%] girls) were randomized to the intervention (n = 45) or control (n = 45) arms. The mean (SD) age was 16.3 (1.9) years. The intervention group had significantly greater adherence to glucose monitoring goals in the incentive period (50.0% vs 18.9%; adjusted difference, 27.2%; 95% CI, 9.5% to 45.0%; P = .003) but not in the follow-up period (15.3% vs 8.7%; adjusted difference, 3.9%; 95% CI, -2.0% to 9.9%; P = .20). The change in HbA1c levels from baseline did not differ significantly between groups at 3 months (adjusted difference, -0.08%; 95% CI, -0.69% to 0.54%; P = .80) or 6 months (adjusted difference, 0.03%; 95% CI, -0.55% to 0.60%; P = .93). Among adolescents and young adults with type 1 diabetes, daily financial incentives improved glucose monitoring adherence during the incentive period but did not significantly improve glycemic control. clinicaltrials.gov Identifier: NCT02568501.

Although cross-sectional studies have shown a positive association between Se and cholesterol concentrations, a recent randomised controlled trial in 501 elderly UK individuals of relatively low-Se status found that Se supplementation for 6 months lowered total plasma cholesterol. The Danish PRECISE (PREvention of Cancer by Intervention with Selenium) pilot study (ClinicalTrials.gov ID: NCT01819649) was a 5-year randomised, double-blinded, placebo-controlled trial with four groups (allocation ratio 1:1:1:1). Men and women aged 60-74 years (n 491) were randomised to 100 (n 124), 200 (n 122) or 300 (n 119) μg Se-enriched yeast or matching placebo-yeast tablets (n 126) daily for 5 years. A total of 468 participants continued the study for 6 months and 361 participants, equally distributed across treatment groups, continued for 5 years. Plasma samples were analysed for total and HDL-cholesterol and for total Se concentrations at baseline, 6 months and 5 years. The effect of different doses of Se supplementation on plasma lipid and Se concentrations was estimated by using linear mixed models. Plasma Se concentration increased significantly and dose-dependently in the intervention groups after 6 months and 5 years. Total cholesterol decreased significantly both in the intervention groups and in the placebo group after 6 months and 5 years, with small and nonsignificant differences in changes in plasma concentration of total cholesterol, HDL-cholesterol, non-HDL-cholesterol and total:HDL-cholesterol ratio between intervention and placebo groups. The effect of long-term supplementation with Se on plasma cholesterol concentrations or its sub-fractions did not differ significantly from placebo in this elderly population.

Overweight and obesity are globally increasing risk factors for diseases in the context of metabolic syndrome. A randomized controlled trial was conducted to investigate whether there are any existing differences between two lifestyle intervention strategies with respect to weight reduction after 1 year. A total of 166 subjects with a body mass index of 28-35 kg/m 2 were enrolled in this trial at seven study centers; 109 were randomly allocated to the intervention group (comprehensive lifestyle modification program: web-based Individual Health Management [IHM]) with 3-month reduction phase plus 9-month maintenance phase, and 57 were allocated to the control group (written information with advice for healthy food habits: usual care [UC]). Body weight, waist circumference, blood pressure, laboratory findings, and bioimpedance analysis used to determine body composition were measured at baseline and after 3, 6, 9, and 12 months. The primary outcome parameter was body weight at month 12 compared to baseline. With respect to baseline status there were no statistically significant differences between the groups. Based on the intent-to-treat population, body weight showed a mean decrease of 8.7 kg (SD 6.1) in the intervention group (IHM) and 4.2 kg (SD 5) in the control group (UC) at month 12. This statistically significant difference ( P <0.001) was confirmed by various sensitivity analyses. Body mass index, waist circumference, high-density lipid cholesterol, body fat, and the ratio of fat and body cell mass improved to a significantly higher degree in the IHM group. IHM proved to be superior to UC in weight reduction after 1 year. With a mean loss of about 10% of the baseline weight, a clinically high relevant risk reduction for cardio-metabolic diseases is achievable.

Serotonin abnormalities in Engrailed-2 knockout mice: New insight relevant for a model of Autism Spectrum Disorder.

Autism spectrum disorder (ASD) is a congenital neurodevelopmental behavioral disorder that appears in early childhood. Recent human genetic studies identified the homeobox transcription factor, Engrailed 2 (EN2), as a possible ASD susceptibility gene. En2 knockout mice (En2-/-) display subtle cerebellar neuropathological changes and reduced levels of tyrosine hydroxylase, noradrenaline and serotonin in the hippocampus and cerebral cortex similar to those ones which have been observed in the ASD brain. Furthermore other similarities link En2 knockout mice to ASD patients. Several lines of evidence suggest that serotonin may play an important role in the pathophysiology of the disease. In the present study we measured, by using an HPLC, the 5-HT levels in different brain areas and at different ages in En2-/- mice. In the frontal and occipital cortex, the content of 5HT was reduced in En2-/- 1 and 3 months old mice; in 6 month old mice, the difference was still present, but it was not statistically significant. The 5-HT content of cerebellar cortex was significantly reduced at 1 month old but significantly high when the KO mice reached 3 months of age. The increase was present even at 6 months of age. A similar trend was highlighted by SERT immunolabeling in En2-/- mice compared to control in the same areas and age analyzed. Our findings, in agreement with the current knowledge on the 5-HT system alterations in ASD, confirm the early neurotransmitter deficit with a late compensatory recovery in En2 KO-mice further suggesting that this experimental animal may be considered a good predictive model for the human disease.

To assess the efficacy and safety of transcatheter arterial chemoembolization (TACE) plus S-1 for the treatment of Barcelona Clinic Liver Cancer (BCLC) Stage B HCC refractory to TACE. 26 patients meeting the eligibility criteria were enrolled. TACE was given on day 1, and S-1 on days 2-15. Tumor assessment was performed one month later according to mRECIST. The primary endpoints were TTP and OS. Twenty-six patients received 176 TACE interventions in all. Fifteen patients of TACE plus S-1 received a total of 55 cycles of treatment of S-1, with a median of 4 cycles (range, 2-6). The total dose of S-1 was 6165 mg per day, while average was 120 mg (range, 100-125 mg) for 15 patients of TACE plus S-1. Median TTP and OS of TACE plus S-1 were 6 months (95% CI: 4.7-7.3) and 18 months (95% CI: 15.3-24.7), respectively, while TACE monotherapy was 4 months (95% CI: 2.4-5.6) and 13 months (95% CI: 9.8-16.2), respectively, and significant differences were detected. Though there were higher DCRs in patients of TACE plus S-1, no significant differences were detected. A total of 612 adverse events occurred during the course of the treatment, 367 in TACE plus S-1 and 245 in TACE mono-therapy. There were significant differences to anorexia and nausea, but they were tolerable. TACE plus S-1 in the present analysis was tolerable and associated with an interesting TTP and OS. TACE plus S-1 may be used as a new treatment method to BCLC Stage B HCC refractory to TACE.

Background Azilsartan is an angiotensin II receptor blocker with a potent antihypertensive effect. Methods In a multicenter, prospective, open-label study, 265 patients with poor blood pressure control despite treatment with other angiotensin II receptor blockers were switched to 20 mg/day of azilsartan (patients on standard dosages) or 40 mg/day of azilsartan (patients on high dosages). Results Blood pressure was 149/83 mm Hg before switching and was significantly reduced from 1 month after switching until final assessment (132/76 mm Hg, P < 0.001). The pulse rate was 72/min before switching and increased significantly from 3 months after switching until final assessment (74/min, P < 0.005). A significant decrease of home morning systolic and diastolic pressure was observed from 1 and 3 months, respectively. Home morning blood pressure was 143/82 mm Hg before switching and 130/76 mm Hg at final assessment (P < 0.01). The morning-evening difference of systolic blood pressure decreased from 14.6 to 6.6 mm Hg after switching (P = 0.09). The estimated glomerular filtration rate was significantly decreased at 3, 6, and 12 months after switching, and serum uric acid was significantly increased at 12 months. No serious adverse events occurred. Conclusion Azilsartan significantly reduced the blood pressure and decreased diurnal variation in patients responding poorly to other angiotensin II receptor blockers. PMID:29238433

To compare the effectiveness of anatomical single-bundle (ASB) and over-the-top single-bundle (OSB) reconstruction of the anterior cruciate ligament (ACL). Between January 2008 and June 2008, 64 patients with ACL injury underwent arthroscopic ACL reconstruction. ASB ACL reconstruction was performed in 28 cases (ASB group) and OSB ACL reconstruction in 36 cases (OSB group). There was no significant difference in gender, age, disease duration, International Knee Documentation Committee (IKDC) score, Lysholm score, and side-to-side difference between 2 groups (P > 0.05). All incisions healed by first intention; no infection or other complications occurred. All cases were followed up 20-24 months (mean, 21.5 months). There were significant differences in the IKDC score, Lysholm score, and the side-to-side difference between last follow-up and preoperation in 2 groups (P < 0.05), but there was no significant difference between 2 groups at last follow-up (P > 0.05). Significant differences were found in negative rate of the pivot shift test between last follow-up and preoperation in ASB group and between 2 groups at last follow-up (P < 0.05), but there was no significant difference between last follow-up and preoperation in OSB group (P > 0.05). The effectiveness of arthroscopic ASB ACL reconstruction is better than that of arthroscopic OSB ACL reconstruction, especially in controlling rotational stability.

To determine whether there was a difference in retention of knowledge about pressure ulcers with a traditional lecture versus computer-based instruction. A quasi-experimental, pretest/posttest design was used. Medical-surgical and critical care nurses (N = 60) were randomly assigned to a lecture, to computer-based instruction, or to a control group. Study participants were given the pressure ulcer knowledge test before and immediately after the program and at 3-month and 6-month intervals. Analysis of variance showed statistically significant differences in pretest and posttest scores [F(2, 57) = 35.784, p = .000] and in posttest to 3-month scores [F(2, 57) = 18.427, p = .000] among the three groups. The most significant loss of pressure ulcer knowledge, regardless of educational method, occurred within the first 3 months. Based on these findings, quarterly education in pressure ulcer prevention is recommended to maintain knowledge. Computer-based instruction is a viable option for acquisition and retention of knowledge about pressure ulcer prevention. Copyright 2011, SLACK Incorporated.

A work environment and health questionnaire was administered 2 and 1 month(s) pre-intervention and 3, 6, and 12 months post-intervention. Multi-level statistical models tested hypotheses. Results The CWT intervention lowered daily visual symptoms (p < 0.01) post-intervention. The TO group did not significantly differ from the control group. The CWT group differed significantly from the TO group (p = 0.01) post-intervention. Conclusion Workers who received a highly adjustable chair and office ergonomics training had reduced visual symptoms and the effect was maintained through twelve months post-intervention. The lack of a training-only group effect supports implementing training in conjunction with the highly adjustable chair to reduce visual symptoms. PMID:21963250

Hybrid striped bass (Morone chrysops X Morone saxatilis ) are an important aquaculture species yet there are few diagnostic tools available to assess their health. Hematology and clinical chemistry analyses are not used extensively in fish medicine due to the lack of reference intervals for various fish species, and because factors such as age can affect blood values. There is little published information regarding age-related changes in blood values of juvenile fish. It is important to evaluate juvenile fish, as this is the time they are raised in aquaculture settings. Determining age-related changes in the blood values of fishes would further develop clinical pathology as a diagnostic tool, enhancing both fish medicine and the aquaculture industry. The results of standard hematology and clinical chemistry analysis were evaluated in juvenile hybrid striped bass at 4, 6, 9, 15, and 19 months of age. Values for PCV and RBC indices were significantly lower, and plasma protein concentration was significantly higher in younger fish. Total WBC and lymphocyte counts were significantly higher in fish at 6 and 9 months of age, while neutrophil and monocyte counts were higher at 6, 9, and 15 months. Eosinophil counts were significantly higher in 9-month-old fish. The majority of hematologic values fell within previously established reference intervals, indicating that only slight modification to the intervals is necessary for evaluating hematologic results of hybrid striped bass at different ages. The following analytes deviated sufficiently from adult reference intervals to warrant separate reference values: plasma protein concentration at 4 months, WBC and lymphocyte counts at 15 and 19 months, and thrombocyte-like-cells at 9 months of age. Values for most biochemical analytes were significantly different among age groups except for creatinine and potassium concentrations. Comparisons with reference intervals were not made for biochemical analytes, because established reference intervals were not available. Age-related changes in hematologic and biochemical values of striped bass were similar to those reported for rainbow trout and mammals.

Large vestibular aqueduct syndrome: Impedance changes over time with different cochlear implant electrode arrays.

The aim of this study was to assess if large vestibular aqueduct syndrome (LVAS), with the increase in perilymphatic pressure, affects impedance changes over time with different types of Cochlear(®) implant electrode arrays Contour, Straight, and CI 422. To report speech perception outcomes for these cochlear implant recipients. Retrospective case review of impedance levels and categories of auditory performance. Impedance data were collected at switch on, 1 month, 3, 6, 12, and 24 months after cochlear implantation and compared with control (non-LVAS cochlear implant recipient) data for each array type. Forty-seven patients with exclusive LVAS and no other vestibulocochlear abnormalities or other identifiable cause of deafness were eligible for inclusion in the study. In LVAS patients, there was a significant difference in impedance between the three types of device (P < 0.0001). Time since switch on was associated with a decrease in impedance for all three devices (P < 0.0001). The mean impedance reduced between switch on and 1 month and remained relatively constant thereafter. Sound variation with softening of sounds was seen in four CI 422 (Straight Research Array) recipients due to ongoing fluctuations in electrode compliance. For all three array types, there was no significant difference in the mean impedance between the LVAS patients and controls over the first 12 months. In keeping with previous studies cochlear implant recipients with LVAS hear very well through the cochlear implant.

The optimal age for introducing complementary feeding to breast-fed infants may differ depending on the setting. Prolonged exclusive breast-feeding (EBF) protects against infection but may increase the risk of iron deficiency (ID)/anaemia (IDA) in vulnerable infants. The aim of the present study was to compare haemoglobin (Hb), serum ferritin (SF), anaemia (Hb < 11 g/L), ID (SF < 12 μg/L) and IDA (Hb < 10.5 g/dL + Hct < 33% + ID) using observational analyses in 6-month old infants from Bogota, Colombia who were EBF for 4 to 5 versus 6 months or older, and examine predictors. Infant feeding was recorded, anthropometry performed, and blood obtained for Hb and SF at 6 months in healthy term infants (birth weight > 2500 g), all EBF for ≥4 months. One hundred eight infants (54% boys) were recruited; 46% EBF for 4 to 5 months, 54% EBF at 6 months. Prevalence of anaemia, ID, and IDA was 20%, 10%, and 5%, with no significant difference between EBF4-5 and EBF6 groups. In multivariate models, anaemia/ID were predicted by greater weight gain from 0 to 6 months, and anaemia also by caesarean delivery; Hb was lower in infants with higher intake of cows' milk; SF was lower in boys and those with greater weight gain. EBF4-5 versus EBF6 was not a significant predictor of any outcome. Anaemia and ID were common at 6 months but were not affected by EBF for 4 to 5 versus 6 months, suggesting 6 months EBF is safe in this population. Further research is, however, required to examine effects on later iron status. The findings highlight the need to emphasise avoidance of cow's milk before 12 months.

To determine whether raloxifene, a selective estrogen receptor modulator, improves cognitive function compared with placebo in women with Alzheimer disease (AD) and to provide an estimate of cognitive effect. This pilot study was conducted as a randomized, double-blind, placebo-controlled trial, with a planned treatment of 12 months. Women with late-onset AD of mild to moderate severity were randomly allocated to high-dose (120 mg) oral raloxifene or identical placebo provided once daily. The primary outcome compared between treatment groups at 12 months was change in the Alzheimer's Disease Assessment Scale, cognitive subscale (ADAS-cog). Forty-two women randomized to raloxifene or placebo were included in intent-to-treat analyses (mean age 76 years, range 68-84), and 39 women contributed 12-month outcomes. ADAS-cog change scores at 12 months did not differ significantly between treatment groups (standardized difference 0.03, 95% confidence interval -0.39 to 0.44, 2-tailed p = 0.89). Raloxifene and placebo groups did not differ significantly on secondary analyses of dementia rating, activities of daily living, behavior, or a global cognition composite score. Caregiver burden and caregiver distress were similar in both groups. Results on the primary outcome showed no cognitive benefits in the raloxifene-treated group. This study provides Class I evidence that for women with AD, raloxifene does not have a significant cognitive effect. The study lacked the precision to exclude a small effect. © 2015 American Academy of Neurology.

To examine a possible relationship between pineal function and the sudden infant death syndrome (SIDS), samples of whole blood, ventricular cerebrospinal fluid (CSF) and/or vitreous humor (VH) were obtained at autopsy from 68 infants (45 male, 23 female) whose deaths were attributed to either SIDS (n = 32, 0.5-5.0 months of age; mean plus or minus S.E.M., 2.6 plus or minus 0.2 months) or other causes (non-SIDS, n = 36, 0.3-8.0 months of age 4.3 plus or minus 0.3 months). The melatonin concentrations were measured by radioimmunoassay. A significant correlation was observed for melatonin levels in different body fluids from the same individual. After adjusting for age differences, CSF melatonin levels were significantly lower among the SIDS infants (91 plus or minus 29 pmol/l; n = 32) than among those dying from other causes (180 plus or minus 27; n = 35, P less than 0.05). A similar, but non-significant trend was also noted in blood (97 plus or minus 23, n = 30 vs. 144 plus or minus 22 pmol/l, n = 33) and vitreous humor (68 plus or minus 21, n = 10 vs. 81 plus or minus 17 pmol/l, n = 15). These differences do not appear to be explainable in terms of the interval between death and autopsy, gender, premortem infection, or therapeutic measures instituted prior to death. Diminished melatonin production may be characteristic of SIDS and could represent an impairment in the maturation of physiologic circadian organization.

We describe our experiences with, and compare the outcomes of, 2 groups of renal transplant patients treated with thymoglobulin or antithymocyte globulin-Fresenius as induction therapy at transplant to reduce the incidence of acute rejection and prevent delayed allograft function. Twenty-four recipients of deceased-donor or living-donor kidney transplants received thymoglobulin, and 23 patients received antithymocyte globulin-Fresenius. Patient and graft survival and efficacy and safety were assessed at 3 months. The demographic characteristics of both groups were comparable, but the predominant donor type was significantly different. Incidence of complications, delayed graft function, and creatinine concentrations were comparable in both groups. At 3 months after the transplant, patient survival rate was 92% in the thymoglobulin group and 96% in the antithymocyte globulin-Fresenius group (P > .05), and death-censored graft survival rate for both groups was not significantly different. Average hematocrit and lymphocyte, neutrophil, and platelet counts were comparable in both groups at 3 months' follow-up. Average white blood count at 1 month was significantly different between the groups: at 5.62 ± 2.45 × 103 cells/mm³ in the thymoglobulin group and 7.85 ± 4.10 × 103 cells/mm³ in the ATG-F group (P < .05). Considering the study design limitations, we observed that our group of treated patients, safety, and efficacy of thymoglobulin and antithymocyte globulin-Fresenius were generally comparable.

To determine the addition of value of neoadjuvant, concurrent and adjuvant chemotherapy to radiation in the treatment of nasopharyngeal carcinoma with regard to the overall survival (OS) and disease free survival (DFS) within a six year period in Tehran cancer institute. Files of all patients with nasopharyngeal carcinoma treated by radiotherapy with or without concurrent chemotherapy in a curative setting in Tehran cancer institute during the period of 1999-2005 were retrospectively reviewed.. A total of 103 patients with nasopharyngeal carcinoma had been treated during the study period with radiotherapy or chemoradiotherapy in our institute. There were 29 (28.2%) females and 74 (71.8%) males. The median age at the time of radiotherapy was 47 years old (range 9-75 years). The patients were followed 2 to 76 months with a median follow-up of 14 months. Time of first recurrence after treatment was 3-44 months with a median of 10 months.. Survival in 2 groups of patients treated with radiotherapy alone or chemoradiation did not have a significant difference (P>0.1). Two-year survival in patients treated with or without adjuvant chemotherapy and had local recurrence after treatment did not have significant difference (P>0.1). Two-year survival in patients with or without local recurrence after treatment did not have significant difference (P>0.1). A beneficial affect or a survival benefit of adjuvant/neoadjuvant chemotherapy and concurrent chemoradiation was not observed in Iranian patients.

Pain is a common and significant symptom in many individuals with multiple sclerosis (MS). The presence and severity of pain in individuals with MS has also been shown to be associated with higher levels of depression, functional impairment, and fatigue. It is common for MS patients and their caregivers to worry about narcotic addiction in the management of chronic pain. Therefore, this study aimed to determine and compare the effects of reflexology and relaxation on pain in women suffering from MS. This study was a single-blind randomized clinical trial performed on 75 patients with MS referred to the MS Clinic of Ayatollah Kashani Hospital (Isfahan, Iran). After simple non-random sampling, using the minimization method, participants were randomly assigned to the three groups of reflexology, relaxation, and control. In the experimental groups, foot reflexology and relaxation interventions (Jacobson and Benson) were performed within 4 weeks, twice a week for 40 min. The control group received routine care and medical treatment as directed by a doctor. Data were collected using the Numerical Rating Scale before, immediately after, and 2 months after interventions in all three groups. Data analysis was performed using SPSS version 18 and descriptive and inferential statistical tests. Findings obtained from analysis of variance (ANOVA) showed no significant differences between mean pain intensity scores in the three groups preintervention and 2 months after interventions (p > 0.05). However, this difference was statistically significant immediately after the study (p < 0.05). Findings obtained from repeated measures ANOVA showed that the severity of pain significantly differed during different times in reflexology and relaxation (p < 0.05); however, this difference was not significant in the control group (p > 0.05). Furthermore, Fisher's least significant difference (LSD) revealed a significantly higher reduction in pain intensity scores in the reflexology group after the intervention, compared with the two other groups, but showed no significant differences between relaxation and control groups. There were no significant differences between the three groups 2 months after the interventions (p > 0.05). The results showed that both interventions are effective on relieving pain in women with MS; however, it appears that the effect of reflexology on pain reduction is greater than that of relaxation. Hence, these two methods can be recommended as effective techniques.

The EXCEL (Evaluation of Xience Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial compared outcomes in patients with unprotected left main coronary artery disease (LMCAD) treated with coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI) using everolimus-eluting stents. Whereas rates of death, stroke, and myocardial infarction were similar at 36 months, event timing and repeat revascularization rates differed by treatment group. To understand the effects of revascularization strategy from the patient's perspective, a prospective quality of life (QoL) substudy was performed alongside the EXCEL trial. Between September 2010 and March 2014, 1,905 patients with LMCAD were randomized to undergo CABG or PCI, of whom 1,788 participated in the QoL substudy. QoL was assessed at baseline and 1, 12, and 36 months using the Seattle Angina Questionnaire, the 12-Item Short Form Health Survey, the Rose Dyspnea Scale, the Patient Health Questionnaire-8, and the EQ-5D. Differences between PCI and CABG were assessed using longitudinal random-effect growth curve models. Over 36 months, both PCI and CABG were associated with significant improvements in QoL compared with baseline. At 1 month, PCI was associated with better QoL than CABG. By 12 months though, these differences were largely attenuated, and by 36 months, there were no significant QoL differences between PCI and CABG. Among selected patients with LMCAD, both PCI and CABG result in similar QoL improvement through 36 months, although a greater early benefit is seen with PCI. Taken together with the 3-year clinical results of EXCEL, these findings suggest that PCI and CABG provide similar intermediate-term outcomes for patients with LMCAD.

Exclusive breast-feeding (EBF) is the practice of feeding only breast milk (including expressed breast milk) during the first six months and no other liquids and solid foods except medications. The time to cessation of exclusive breast-feeding, however, is different in different countries depending on different factors. Studies showed the risk of diarrhea morbidity and mortality is higher among none exclusive breast-feeding infants, common during starting other foods. However, there is no study that evaluated the time to cessation of exclusive breast-feeding in the study area. The aim of this study was to show time to cessation of EBF and its predictors among mothers of index infants less than twelve months old. We conducted a community-based cross-sectional study from February 13 to March 3, 2012 using both quantitative and qualitative methods. This study included a total of 592 mothers of index infant using multi-stage sampling method. Data were collected by using interviewer administered structured questionnaire. Bivariate and multivariate Cox regression analyses were performed. Cessation of exclusive breast-feeding occurred in 392 (69.63%) cases. Among these, 224 (57.1%) happened before six months, while 145 (37.0%) and 23 (5.9%) occurred at six months and after six months of age of the index infant respectively. The median time for infants to stay on exclusive breast-feeding was 6.36 months in rural and 5.13 months in urban, and this difference was statistically significant on a Log rank (Cox-mantel) test. Maternal and paternal occupation, place of residence, postnatal counseling on exclusive breast-feeding, mode of delivery, and birth order of the index infant were significant predictors of cessation of exclusive breast-feeding. Providing postnatal care counseling on EBF, routine follow-up and support of those mothers having infants stressing for working mothers can bring about implementation of national strategy on infant and young child feeding.

Black smokers have demonstrated greater lung cancer disease burden and poorer smoking cessation outcomes compared with whites. Lung cancer screening represents a unique opportunity to promote cessation among smokers; however, little is known about the differential impact of screening on smoking behaviors among black and white smokers. Using data from the National Lung Screening Trial (NLST), we examined the racial differences in smoking behaviors after screening. We examined racial differences in smoking behavior and cessation activity among 6,316 white and 497 black (median age, 60 and 59 years, respectively) NLST participants who were current smokers at screening using a follow-up survey on 24-hour and 7-day quit attempts, 6-month continuous abstinence, and the use of smoking cessation programs and aids at 12 months after screening. Using multiple regression analyses, we examined the predictors of 24-hour and 7-day quit attempts and 6-month continuous abstinence. At 12 months after screening, blacks were more likely to report a 24-hour (52.7% vs. 41.2%, p < .0001) or 7-day (33.6% vs. 27.2%, p = .002) quit attempt. However, no significant racial differences were found in 6-month continuous abstinence (5.6% blacks vs. 7.2% whites). In multiple regression, black race was predictive of a higher likelihood of a 24-hour (odds ratio [OR], 1.6, 95% confidence interval [CI], 1.2-2.0) and 7-day (OR, 1.5, 95% CI, 1.1-1.8) quit attempt; however, race was not associated with 6-month continuous abstinence. Only a positive screening result for lung cancer was significantly predictive of successful 6-month continuous abstinence (OR, 2.3, 95% CI, 1.8-2.9). Although blacks were more likely than whites to have 24-hour and 7-day quit attempts, the rates of 6-month continuous abstinence did not differ. Targeted interventions are needed at the time of lung cancer screening to promote abstinence among all smokers. Among smokers undergoing screening for lung cancer, blacks were more likely than whites to have 24-hour and 7-day quit attempts; however, these attempts did not translate to increased rates of 6-month continuous abstinence among black smokers. Targeted interventions are needed at the time of lung cancer screening to convert quit attempts to sustained smoking cessation among all smokers. ©AlphaMed Press.

To investigate the clinical efficacy of three toothpastes in controlling established gingivitis and plaque over 6 months. 135 subjects were enrolled in a single-center, double-blind, parallel group, randomized clinical study. Subjects were randomly assigned to one of three treatments: triclosan/copolymer/fluoride dentifrice containing 0.3% triclosan, 2.0% copolymer and 1,450 ppm F as sodium fluoride in a silica base; herbal/bicarbonate dentifrice containing herbal extract and 1,400 ppm F as sodium fluoride in a sodium bicarbonate base; or fluoride dentifrice containing 450 ppm F as sodium fluoride, and 1,000 ppm F as sodium monofluorophosphate. Subjects were instructed to brush their teeth twice daily for 1 minute for 6 months. After 6 months, subjects assigned to the triclosan/copolymer/fluoride group exhibited statistically significant reductions in gingival index scores and plaque index scores as compared to subjects assigned to the herbal/bicarbonate group by 35.4% and 48.9%, respectively. There were no statistically significant differences in gingival index and plaque index between subjects in the herbal/ bicarbonate group and those in the fluoride group. The triclosan/copolymer/fluoride dentifrice was statistically significantly more effective in reducing gingivitis and dental plaque than the herbal/bicarbonate dentifrice, and this difference in efficacy was clinically meaningful.

The purpose of this investigation was to evaluate the relative efficacy of two consultation-based models for designing academic interventions to enhance the educational functioning of children with attention-deficit/hyperactivity disorder (ADHD). Children (N=167) meeting DSM-IV criteria for ADHD were randomly assigned to one of two consultation groups: Individualized Academic Intervention (IAI; interventions designed using a data-based decision-making model that involved ongoing feedback to teachers) and Generic Academic Intervention (GAI; interventions designed based on consultant-teacher collaboration, representing "consultation as usual"). Teachers implemented academic interventions over 15 months. Academic outcomes (e.g., standardized achievement test, and teacher ratings of academic skills) were assessed on four occasions (baseline, 3 months, 12 months, 15 months). Hierarchical linear modeling analyses indicated significant positive growth for 8 of the 14 dependent variables; however, trajectories did not differ significantly across consultation groups. Interventions in the IAI group were delivered with significantly greater integrity; however, groups did not differ with respect to teacher ratings of treatment acceptability. The results of this study provide partial support for the effectiveness of consultation-based academic interventions in enhancing educational functioning in children with ADHD; however, the relative advantages of an individualized model over "consultation as usual" have yet to be established.

Organ shortage is the most significant factor in restricting the activities of transplantation systems. We herein report the positive impact of Muslims' holy month of Ramadan on willingness to donate organs in Iran. Data were derived from the database of Donation Willingness Registries, affiliated to the organ procurement unit of Masih Daneshvari Hospital during March 2007 till March 2008. The number of applications for organ donation was compared between Ramadan and its previous month, and the socio-economic characteristics of the applicants were compared between those who applied in Ramadan and those who did so in the previous month. In addition, the mean number of daily applications was compared between Ramadan and the other months of the same year. A total of 11528 applications for organ donation cards were registered for the Ramadan of 2007 as opposed to 4538 applications in the previous month, showing an increasing rate of 154%. The mean number of daily applications was significantly higher in Ramadan than that of the other months of the same year (P < 0.001). There was also a significant difference in terms of the socio-economic characteristics between the applicants in Ramadan and those in the previous month. The increase in organ donation willingness in Ramadan may be the result of the propagation of altruism by the mass media and religious organizations. Ramadan seems to provide a great opportunity to promote organ donation across the Muslim world.

Perinatal grief differs from other types of mourning. Two goals were set: to describe the progression of the process of grief and the symptoms of depression throughout the year following perinatal loss, and to study its association with socio-economic and obstetric factors. The study involved the participation of 70 women who had suffered a medical termination of pregnancy or a prenatal/postnatal death. Three assessments were made after the loss (after 1 month, 6 months and 1 year) with the Perinatal Grief Scale (PGS) to assess grief and the Beck Depression Inventory (BDI) for depressive symptomatology. Symptoms pertaining to grief and depression were observed in the first month after the loss, and a significant decrease in scores over the two follow-ups. No significant differences were observed in grief and depression depending on the type of loss, no significant associations were found with the age of the mother, her socioeconomic level, or obstetric factors (week of gestation of the loss, having a child or having suffered a previous miscarriage). Perinatal grief is a complex construct, with multiple variables involved, and one which involves significant emotional discomfort.

The aim of this randomized, controlled, clinical study was to compare two surgical techniques with the acellular dermal matrix graft (ADMG) to evaluate which technique could provide better root coverage. Fifteen patients with bilateral Miller Class I gingival recession areas were selected. In each patient, one recession area was randomly assigned to the control group, while the contra-lateral recession area was assigned to the test group. The ADMG was used in both groups. The control group was treated with a broader flap and vertical-releasing incisions, and the test group was treated with the proposed surgical technique, without releasing incisions. The clinical parameters evaluated before the surgeries and after 12 months were: gingival recession height, probing depth, relative clinical attachment level and the width and thickness of keratinized tissue. There were no statistically significant differences between the groups for all parameters at baseline. After 12 months, there was a statistically significant reduction in recession height in both groups, and there was no statistically significant difference between the techniques with regard to root coverage. Both surgical techniques provided significant reduction in gingival recession height after 12 months, and similar results in relation to root coverage.

Anesthesiology residency programs commonly have rotations at free-standing children's hospitals to provide and/or supplement their residents' training in pediatric anesthesia. Length and timing of these rotations differ from program to program as can their residents' existing medical knowledge and clinical skills. We predicted that residents with prior pediatric anesthesia experience, who rotate at our pediatric institution for two consecutive months, will score higher on an exit exam compared to residents without prior pediatric experience or those that only rotate for one month. A 50-question multiple choice test was created using pediatric questions released from The American Board of Anesthesiology (ABA) written examinations. The test was administered and proctored at the end of each rotation. Study participants came from three different programs: Program A offers prior pediatric anesthesia experience and a one month rotation; Program B - offers prior pediatric anesthesia experience and a two month rotation; and Program C - does not offer prior pediatric anesthesia experience but includes a two month rotation. The 2014-2015 cohort consisted of 26 rotating second-year clinical anesthesia (CA-2) residents. One resident's exam scores were excluded from this study due to protocol violation. Mean exam scores for Program A, B, and C were 70.5% ± 5.7, 64.2% ± 7.0, and 67.3% ± 4.3, respectively. There was no statistically significant difference in the exit exam scores among the three groups. Prior pediatric anesthesia experience or length of time for subspecialty rotation was not associated with any significant difference in exit exam scores for CA-2 residents.

The aim of the study was to comparatively evaluate the psychological and functional effect of different primary treatments in patients with prostate cancer. We conducted a single-center prospective non randomized study in a real-life setting using functional and psychological questionnaires in prostate cancer cases submitted to radical prostatectomy, external radiotherapy, or active surveillance. Totally, 220 cases were evaluated at baseline and during the follow-up at 1-, 3-, 6-, and 12-month interval after therapy. Patients self-completed questionnaires on urinary symptoms and incontinence, erectile and bowel function, psychological distress (PD), anxiety, and depression. Several significant differences among the three groups of treatment were found regarding the total score of the functional questionnaires. Regarding PD, cases submitted to radical prostatectomy showed stable scores during all the 12 months of follow-up whereas cases submitted to radiotherapy showed a rapid significant worsening of scores at 1-month interval and persistent also at 6- and 12-month interval. Cases submitted to active surveillance showed a slight and slow worsening of scores only at 12-month interval. PD and depression resulted to be more associated with urinary symptoms than sexual function worsening whereas anxiety resulted to be associated either with urinary symptoms or sexual function worsening. The results of our comparative and prospective analysis could be used to better inform treatment decision-making. Patients and their teams might wish to know how functional and psychological aspects may differently be influenced by treatment choice. Copyright © 2018 Elsevier Inc. All rights reserved.
