Introduction Diabetes mellitus is a chronic disease affecting many parts of the body. A number of oral diseases have been associated with diabetes mellitus with an increased risk of dental caries and periodontal disease. Aim The aim of the study was to evaluate the salivary pH and incidence of dental caries and periodontal status in diabetes mellitus compared to that of the normal subjects. Materials and Methods The study population consisted of 40 patients divided into 2 groups with group I comprising of 20 known diabetes mellitus patients and group II comprising of 20 non diabetic subjects as control group. The pH of the saliva was determined using a digital pH meter. Dental caries and periodontal status were assessed by DMFT and PDI indices respectively. Results There was a decrease in the mean salivary pH of 6.51 in the study group, compared to the normal mean salivary pH of 7.88 in the control group. The mean DMFT index was higher in the study group (8.10) when compared to that of control group (1.15). The mean PDI score was also higher in the study group (4.0) as compared to that of the control group (0.45). Conclusion The results of the present study concluded that there was a significant relationship between the diabetes mellitus and increased incidence of dental caries and periodontitis and there was also a significant reduction in the salivary pH in diabetes mellitus patients, compared to that of non diabetic subjects.

To compare the operative outcome of carpal tunnel release between limited open carpal tunnel release using direct vision and tunneling technique (group A) with standard open carpal tunnel release (group B). Twenty-eight patients were enrolled in the present study. A single blind randomized control trial study was conducted to compare the postoperative results between group A and B. The study parameters were Levine's symptom severity and functional score, grip and pinch strength, and average two-point discrimination. The postoperative results between two groups were comparable with no statistical significance. Only grip strength at three months follow up was significantly greater in group A than in group B. The limited open carpal tunnel release in the present study is effective comparable to the standard open carpal tunnel release. The others advantage of this technique are better cosmesis and improvement in grip strength at the three months postoperative period.

The aim of this study was to use transthoracic Doppler echocardiographic (TTE) imaging methods to identify cardiac dysfunction, an indicator of subclinical atherosclerosis in asymptomatic systemic lupus erythematosus (SLE) patients in terms of cardiac effects. This study involved 80 patients: a study group (n = 50) and control group (n = 30). They were categorized into four subgroups: anticardiolipin antibodies (aCL) (+) (n = 14) and aCL (-) (n = 36); systemic lupus erythematosus disease activity index (SLEDAI) ≥ 6 (n = 15) and SLEDAI < 6 (n = 35); disease period ≥ 5 years (n = 21) and disease period < 5 years (n = 29); major organ involvement (+) (n = 19), major organ involvement (-) (n = 31). The ratio of mitral peak velocity of early filling to early diastolic mitral annular velocity (E/E') for the study group was found to be higher than the control (p < 0.01). Systolic septal motion velocity (Ssm) was lower in the study group compared with the control (p < 0.01). Left atrium (LA) dimension was greater in the study group than the control (p < 0.01). Ssm was found to be lower in the aCL (+) patients compared with the control and aCL (-) groups (p < 0.01, p < 0.05, respectively). LA dimension was greater in the aCL (+) and (-) groups compared with the control, (p < 0.01, p < 0.05, respectively) and aCL groups compared with each other (p < 0.05). The E/E' ratio for the aCL (+) and (-) groups was found to be greater than the control (p < 0.05). In the study, both the Ssm and the late diastolic septal velocity (sA') was found to be lower in the SLEDAI ≥ 6 group compared with SLEDAI<6 group, (p < 0.001, p < 0.05, respectively). LA dimension was statistically greater in the SLEDAI ≥ 6 group compared with the SLEDAI <6 group (p < 0.001). E' and early diastolic septal velocity (sE') were statistically lower in the disease period >5 years group compared with the disease period <5 years group (p < 0.01, p < 0.05, respectively). Carrying out regular scans with TTE image of SLE patients is important in order to identify early cardiac involvement during monitoring and treatment. Identifying early cardiac involvement in SLE may lead to a reduction in mortality and morbidity rates. © The Author(s) 2015.

Ceramic veneer fracture has occurred mainly at the incisal edge of the veneer because of greater stress. This study compares and evaluates the fracture resistance ceramic veneers with three different incisal preparations. 15 human permanent maxillary central incisor extracted were selected which were divided into three groups of 5 each having a different Incial design Preparation. Group 1: No Incisal reduction with facio- incisal bevel, Group 2 : 1 mm incisal reduction with butt joint, Group 3 : 1 mm incisal reduction with 1 mm height of Palatal chamfer. It was found that Group III had greater fracture resistance as compared to Group I and Group II. Group I had least fracture resistance as compared to Group II and III. Group II had greater fracture resistance as compared to Group I but less than Group III. Ceramic veneer with 1mm incisal reduction with 1mm height of palatal chamfer showed highest fracture resistance as compared to 1mm incisal reduction with butt joint and no incisal reduction with facial-incisal bevel, in order to achieve better esthetic and functional results. The palatal chamfer margin results in preservation of some peripheral enamel layer, which eliminates the micro leakage at the palatal margin-restoration interface and also effectively counteracting shear stress. This design provides a definite seat for cementation. How to cite the article: Jankar AS, Kale Y, Kangane S, Ambekar A, Sinha M, Chaware S.

The purpose of this study was to evaluate the effects of deep shoulder infections after RCR on patient outcomes. A retrospective chart review was conducted involving all patients with deep shoulder infections after arthroscopic RCR (study group). Another group of patients who were matched with the study group by age, gender and rotator cuff tear size, and did not develop deep shoulder infections after arthroscopic RCR were randomly identified (control group). The two groups were compared in terms of time to start physiotherapy, shoulder function, and delay in return to work. There were 10 patients in each group. The mean time to start physiotherapy after surgery was 145.3 (SD=158.8) days for the study group and 40.0 (SD=13.7) days for the control group (p=.051). The average forward elevation of the operated shoulder was 133 (SD=33.4) degrees for the study group, and 172 (SD=12.0) degrees for the control group (p=0.003). The average time to return to work at preoperative level was 5.6 months for the study group and 3 months for the control group. Deep shoulder infections after RCR significantly impedes time to start physiotherapy, shoulder function, and patients' ability to return to work.

Abstract We aimed to assess the short-term outcomes of per-oral endoscopic myotomy (POEM) compared with laparoscopic Heller myotomy (LHM) for achalasia through a meta-analysis of nonrandomized comparative studies. We searched PubMed, Embase, Medline, Cochrane Library, and Google Scholar for studies that compared POEM and LHM for achalasia and were published between January 1, 2008 and December 31, 2014. The Methodological Index for Nonrandomized Studies (MINORS) was used to evaluate the quality of the studies. Random- and fixed-effects meta-analytical models were used, and between-study heterogeneity was assessed. Four nonrandomized comparative studies that included 317 patients (125 in the POEM group and 192 in the LHM group) met our research criteria and were assessed. There were no differences between the POEM and LHM groups in terms of sex, preoperative Eckhart score, length of myotomy, operation time, length of hospital stay, and complications. The patients in the POEM group were older than those in the LHM group (MD =2.81, 95% CI 0.27–5.35; P = 0.03) with high between-study homogeneity (χ2 = 1.96, df = 2, I2 = 0%; P = 0.38). The patients in the POEM group had a lower Eckardt score after surgery compared with those in the LHM group (MD = −0.30, 95% CI −0.42 to −0.18; P < 0.001) with high between-study homogeneity (χ2 = 0.00, df = 1, I2 = 0%; P = 1.00). The efficacy and safety of POEM appear to be comparable to those of LHM. Multicenter and randomized trials with larger sample size are needed to further compare the efficacy and safety of POEM and LHM for the treatment of achalasia. PMID:26871816

Background The aim of this study was to determine the relationship between suicidal behavior and associated factors such as depression, anxiety, and perceived social support level in cancer patients. Material/Methods The study group included 102 patients who were under treatment in the oncology department and the control group included 100 individuals with similar sociodemographic features. A sociodemographic information form, Beck depression inventory, Beck anxiety inventory, suicidal behavior inventory, suicidal ideation inventory, and multidimensional inventory of perceived social support were used. Results The mean Beck depression inventory and Beck anxiety inventory scores in the study group were significantly higher compared to the control group. Thirteen patients in the study group attempted suicide, whereas 3 individuals attempted suicide in the control group. Similarly, the mean suicide behavior and ideation scores in the study group were significantly higher compared to the control group. The mean total multidimensional inventories of perceived social support score, as well as the mean family and friend sub-inventory scores in the control group were significantly higher compared to the study group. Conclusions This study revealed that depression and anxiety occur frequently in cancer patients. Suicide attempts and ideation are higher in cancer patients compared to the control group. Social support perceived from family and friends is lower in cancer patients. Suicide attempts are correlated with depression, anxiety, low level of perceived social support, and advanced disease stage. PMID:24584172

In this study, we aimed to investigate the effects of occupational therapy and psychosocial interventions on the interpersonal functioning and individual and social performance levels of corresponding patients under the heading of psychosocial treatment approaches in psychiatry clinics as well as the attitudes of the patients in regard to those interventions. In 2013, out of psychotic (schizophrenia, bipolar disorder/mania) and nonpsychotic (depression, obsessive compulsive disorder, alcohol dependence) inpatients in our clinic, 48 patients who participated in occupational activities were included in the study group and 43 patients who did not participate in these activities were included in the control group. We prepared and implemented a 3-item questionnaire constructed by our team, which probed the patients' thoughts on these occupational activities. The Interpersonal Functioning Scale (IFS) and Personal and Social Performance Scale (PSP) were applied to both groups on hospital admission and discharge; variations in scale scores were evaluated on par with sociodemographic variables, and the study and control groups were compared. In total, 91% of the study group provided positive feedback regarding the aforementioned interventions. When comparing the study and control groups, the IFS variance score of the study group did not show a significant difference with respect to that of the control group. A statistically significant difference (p<0.0001) was observed in the PSP scores. Evaluation of the PSP of the occupational activities, focusing on sociodemographics and diagnostic labels, revealed a significant improvement in nonpsychotic patients (p=0.002) compared with psychotic patients, in females (p=0.001) compared with males, in unemployed patients (p=0.0001) compared with employed patients, in single patients (p=0.002) compared with married patients, in less-educated patients (p=0.004) compared with high school graduates, and in patients younger than 45 years (p=0.002) compared with those older than 45 years. The findings of our study showed coherence with the literature regarding similar studies conducted on psychotic subgroups. The results demonstrated significantly positive repercussions, specifically in the treatment of nonpsychotic patients; both groups benefited from occupational activities, as shown by improvements in all psychiatric inpatients' PSP scores in comparison with scores of the control group. We concluded that the recruitment of psychosocial treatment approaches enhanced personal and social performance in the patient groups, thereby leading to additional clinical benefits.

To discuss the types of control groups in randomized controlled trials (RCTs) of Chinese herbal medicine (CHM), and to provide suggestions for improving the design of control group in future clinical studies in this therapeutic area. A search of the Cochrane Library was conducted in July 2005 to identify RCTs of CHM, and 66 RCTs with CHM for type 2 diabetes mellitus were obtained as the basis for further analysis. Of 66 RCTs with CHM for type 2 diabetes mellitus, 61 (92.4%) trials had both a treatment group and a control group. Twenty-seven (40.9%) RCTs compared CHM plus conventional drug vs conventional drug, 24 (36.4%) compared CHM vs conventional drug, 5 (7.6%) compared CHM vs placebo, 3 (4.5%) compared CHM plus conventional drug vs conventional drug plus placebo, 3 (4.5%) compared CHM plus conventional drug vs other CHM, 1 (1.5%) compared CHM vs no treatment, 1 (1.5%) compared CHM plus placebo vs conventional drug plus placebo, 1 (1.5%) compared CHM vs CHM plus conventional drug vs conventional drug vs placebo, and 1 (1.5%) compared CHM vs conventional drug vs CHM plus conventional drug. A variety of control groups were used in RCTs of CHM for type 2 diabetes mellitus, including placebo, active, and no treatment control groups. Justification for selecting particular types of control groups were not provided in the trials reviewed in this study. Different control groups may be appropriate according to the study objectives, and several factors should be considered prior to selecting control groups in future RCTs of CHM. (1) Investigators of CHM who design clinical trials should understand the rationale for selecting different types of control groups; (2) Control groups for RCTs should be selected according to study objectives; (3) Active control groups should select interventions for comparisons that have the strongest evidence of efficacy and prescribe them as recommended; (4) Placebo control groups should select a placebo that mimics the physical characteristics of test intervention as closely as possible and is completely inert; (5) No treatment control groups should only be used when withholding treatment is ethical and objectives outcomes will not be subject to bias due to absent blinding; (6) Crossover control groups may be appropriate in chronic and stable conditions.

Circulating C-reactive protein (CRP) levels are a marker of systemic inflammation and are associated with periodontal disease, a chronic bacterial infection associated with elevation of proinflammatory cytokines and prostaglandins. CRP has been associated with adverse pregnancy outcomes, including preterm delivery, preeclampsia, and intrauterine growth restriction. Furthermore, periodontal disease has been associated with increased risk of preterm low birth weight, low birth weight, and preterm birth. The present study was conducted to assess plasma CRP levels in pregnant women with and without periodontal disease; to evaluate the effect of periodontal therapy on the incidence of preterm delivery; and to compare the incidence of preterm delivery in pregnant women with and without periodontal disease. A total of 90 pregnant women aged between 18-35 years with gestational age between 12-28 weeks were recruited and divided into three equal groups (control group, study group, treatment group) of 30 each. Blood samples were taken for estimation of C-reactive protein levels from all groups at 12-20 weeks of gestation, determined using ultrasensitive turbidimetric immunoassay (QUANTIA-CRP US). The treatment group comprised plaque control, scaling, and root planning and daily rinsing with 0.2% chlorhexidine mouth before 28 weeks of gestation. The mean value of C-reactive protein levels in subjects with periodontal disease was higher compared to control group i.e., 1.20 +/- 0.247 mg/dl and 1.22 +/- 0.250 mg/dl, respectively, compared to 0.713 +/- 0.139 mg/ dl (P = 0.001). The mean value of CRP levels before treatment was greater than the mean value after treatment i.e., 1.22 +/- 0.25 compared to 0.84 +/- 0.189 (P < 0.001). The incidence of preterm delivery (< 37 weeks) was 31.7% in the periodontal disease group (study group) compared to 8.3% in the control group (P = 0.001). The incidence of preterm delivery in the treatment group was 15.0% compared to 31.7% in the nontreatment group (study group). The findings from the study suggest that periodontal disease in pregnant women is associated with increased C- reactive protein levels in early pregnancy, incidence of preterm delivery is higher in pregnant women with periodontal disease compared to healthy controls, periodontal therapy during pregnancy reduces plasma CRP levels and there is decrease in incidence of preterm delivery after periodontal therapy.

Two studies were carried out to examine the persistence (Study 1) and characteristics (Study 2) of mathematics learning disability (MLD) in girls with Turner syndrome or fragile X during the primary school years (ages 5-9 years). In Study 1, the rate of MLD for each syndrome group exceeded the rate observed in a grade-matched comparison group, although the likelihood of MLD persisting through the primary school years was comparable for all three groups. In Study 2, formal and informal math skills were compared across the syndrome groups, a normative group, and children from the normative group who had MLD. Few differences were observed between the Turner syndrome and normative groups. Despite having rote counting and number representation skills comparable to those in the normative group, girls with fragile X had difficulty with counting rules (e.g., cardinality, number constancy). However, this difficulty did not distingush them from the MLD group. Overall, counting skills appear to distinguish the Turner syndrome and fragile X groups, suggesting that the specificity of math deficits emerges earlier for fragile X than Turner syndrome.

The aim of this study was to determine whether molar incisor hypomineralization (MIH) is greater in patients with cleft lip and palate (CLP) who underwent primary alveolar grafting (PAG) as compared with CLP waiting for secondary alveolar grafting (SAG) and with controls. A retrospective analysis of intraoral photographs of 13 CLP patients who underwent a PAG, 28 CLP prior to SAG, and 60 controls without CLP was performed. Mantel-Haenszel χ tests were used to compare the 3 groups for differences in MIH scores, and Wilcoxon rank sum tests were used to compare the groups for differences in average MIH scores. A 5% significance level was used for all tests. Molar incisor hypomineralization scores were significantly higher for the PAG and SAG groups compared with the control group (P < 0.001). The PAG group had significantly higher incisor MIH (P = 0.016) compared with the SAG group. Molar incisor hypomineralization average scores were significantly higher for the 2 graft groups compared with the controls (P < 0.0001). The PAG group had significantly higher average MIH score and average MIH score for incisors compared with the SAG group (P = 0.03). Cleft lip and palate patients have significantly greater MIH compared with controls, and CLP patients with PAGs have significantly greater MIH in the incisor region compared with CLP patients with SAGs, indicating that subjects with PAGs have more severely affected dentition.

Abstract The present study was examined the effects of xylitol feeding on diabetes-associated parameters in nondiabetic rats. Seven-week-old male Sprague-Dawley rats were randomly divided into three groups: control (five rats), sucrose (six rats), and xylitol (six rats). Animal had free access to a commercial rat pellet diet, and ad libitum water, 10% sucrose solution, and 10% xylitol solution were supplied to the control, sucrose, and xylitol groups, respectively. After 3 weeks of feeding of experimental diets, food intakes were significantly (P<.05) lower in the sucrose and xylitol groups compared with the control group. Drink intake was significantly higher in the sucrose group but significantly lower in the xylitol group compared with the control group. Body weight gain was significantly lower in the xylitol group compared with the sucrose group. Weekly nonfasting blood glucose was significantly increased, but fasting blood glucose was significantly decreased, in the sucrose group compared with the control and xylitol groups. Significantly better glucose tolerance was observed in the xylitol group compared with the control and sucrose groups. Serum insulin and fructosamine concentrations were not significantly influenced by the feeding of xylitol or sucrose. Relative liver weight and liver glycogen were significantly increased in the xylitol group compared with the sucrose group, whereas no difference was observed between the xylitol and control groups. Serum total cholesterol and low-density lipoprotein-cholesterol were significantly decreased in the sucrose and xylitol groups, and serum triglyceride of the xylitol group, but not the sucrose group, was significantly increased compared with the control group. Data of this study suggest that xylitol can be a better sweetener than sucrose to maintain diabetes-related parameters at a physiologically safer and stable condition.

Results of awake craniotomy are compared to results of resections done under general anesthesia in patients operated with IMRI control. We hypothesized that stimulation of the cortex and white matter during awake surgery supplements IMRI control allowing for safer resection of eloquent brain area tumors. The study group consisted of 20 consecutive patients undergoing awake craniotomy with IMRI control. Resection outcome of these patients was compared to a control group of 20 patients operated in the same IMRI suite but under general anesthesia without cortical stimulation. The control group was composed of those patients whose age, sex, tumor location, recurrence and histology best matched to patients in study group. Cortical stimulation identified functional cortex in eight patients (40 %). Postoperatively the neurological condition in 16 patients (80 %) in the study group was unchanged or improved compared with 13 patients (65 %) in the control group. In both groups, three patients (15 %) had transient impairment symptoms. There was one patient (5 %) with permanent neurological impairment in the study group compared to four patients (20 %) in the control group. These differences between groups were not statistically significant. There was no surgical mortality in either group and the overall infection rate was 5 %. Mean operation time was 4 h 45 min in the study group and 3 h 15 min in the control group. The study consisted of a limited patient series, but it implies that awake craniotomy with bipolar cortical stimulation may help to reduce the risk of postoperative impairment following resection of tumors located in or near speech and motor areas also under IMRI control.

Hyaluronic acid and glycosaminoglycans have shown positive effects in improving lateral epicondylitis and other tendinosis conditions. Therefore, we designed a prospective, randomized study to compare the effects of a combined sodium hyaluronate and chondroitin sulfate (HA + CS) injection versus a triamcinolone injection in the treatment of lateral epicondylitis. In total, 57 consecutive patients with clinically diagnosed lateral epicondylitis were divided randomly into two groups. In the HA + CS group, 25 patients received a single injection of a solution containing an HA + CS combination and prilocaine HCl, while the 32 patients in the triamcinolone group received a single injection of a solution of triamcinolone and prilocaine HCl. We evaluated the pain and function outcome measures using the Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaire at the beginning of the study, and 3 and 6 months after the injection. Additionally, the Minimum Clinically Important Difference values and percentage changes in the PRTEE subscale scores between the assessments were calculated. No serious adverse events were reported throughout the study. The mean pain and function scores for the HA + CS and triamcinolone groups had significantly improved at 3 months, but the mean function scores in the HA + CS group were statistically significantly better when compared to the triamcinolone group. At 6 months, both groups had significantly improved mean pain and function scores, compared to the baseline scores; however, the mean pain and function scores in the 6-month HA + CS treatment group were better than in the 6-month triamcinolone group. The relative change for the mean total score in the HA + CS group was much better when compared with the triamcinolone group, and the HA + CS treatment group showed clinically significant improvement when compared with triamcinolone group at 3 and 6 months. This study supports the idea that for a single injection treatment of patients with lateral epicondylitis, a combination injection of HA + CS may offer better pain benefits for 6 months after injection, when compared to triamcinolone.

The effectiveness of faculty-directed study groups as an intervention to prepare nurse candidates for NCLEX-RN was evaluated. The NCLEX-RN performance of a baccalaureate class who had participated in study groups was compared to the performance of a prior class who had not participated in study groups. Academic subgroups within the classes were compared to determine if study groups were equally effective across levels of academic achievement. The possible reasons for the significant difference in the NCLEX-RN passing rate between "at-risk" students who participated in study groups and at-risk students who did not participate in study groups are discussed. Discussion also considers possible factors influencing the generally better performance of study group participants at all academic levels. Suggestions for future intervention research direct attention to time intensity of interventions and research control through random assignments to treatment groups.

AIM: To evaluate the induction of remission and maintenance effects of probiotics for ulcerative colitis. METHODS: Information was retrieved from MEDLINE, EMBASE, and the Cochrane Controlled Trials Register. The induction of remission and promotion of maintenance were compared between probiotics treatment and non-probiotics treatment in ulcerative colitis. RESULTS: Thirteen randomized controlled studies met the selection criteria. Seven studies evaluated the remission rate, and eight studies estimated the recurrence rate; two studies evaluated both remission and recurrence rates. Compared with the non-probiotics group, the remission rate for ulcerative colitis patients who received probiotics was 1.35 (95% CI: 0.98-1.85). Compared with the placebo group, the remission rate of ulcerative colitis who received probiotics was 2.00 (95% CI: 1.35-2.96). During the course of treatment, in patients who received probiotics for less than 12 mo compared with the group treated by non-probiotics, the remission rate of ulcerative colitis was 1.36 (95% CI: 1.07-1.73). Compared with the non-probiotics group, the recurrence rate of ulcerative colitis patients who received probiotics was 0.69 (95% CI: 2.47-1.01). In the mild to moderate group who received probiotics, compared to the group who did not receive probiotics, the recurrence rate was 0.25 (95% CI: 0.12-0.51). The group who received Bifidobacterium bifidum treatment had a recurrence rate of 0.25 (95% CI: 0.12-0.50) compared with the non-probiotics group. CONCLUSION: Probiotic treatment was more effective than placebo in maintaining remission in ulcerative colitis. PMID:20397271

To evaluate the induction of remission and maintenance effects of probiotics for ulcerative colitis. Information was retrieved from MEDLINE, EMBASE, and the Cochrane Controlled Trials Register. The induction of remission and promotion of maintenance were compared between probiotics treatment and non-probiotics treatment in ulcerative colitis. Thirteen randomized controlled studies met the selection criteria. Seven studies evaluated the remission rate, and eight studies estimated the recurrence rate; two studies evaluated both remission and recurrence rates. Compared with the non-probiotics group, the remission rate for ulcerative colitis patients who received probiotics was 1.35 (95% CI: 0.98-1.85). Compared with the placebo group, the remission rate of ulcerative colitis who received probiotics was 2.00 (95% CI: 1.35-2.96). During the course of treatment, in patients who received probiotics for less than 12 mo compared with the group treated by non-probiotics, the remission rate of ulcerative colitis was 1.36 (95% CI: 1.07-1.73). Compared with the non-probiotics group, the recurrence rate of ulcerative colitis patients who received probiotics was 0.69 (95% CI: 2.47-1.01). In the mild to moderate group who received probiotics, compared to the group who did not receive probiotics, the recurrence rate was 0.25 (95% CI: 0.12-0.51). The group who received Bifidobacterium bifidum treatment had a recurrence rate of 0.25 (95% CI: 0.12-0.50) compared with the non-probiotics group. Probiotic treatment was more effective than placebo in maintaining remission in ulcerative colitis.

The objective of this study was to investigate if the research process to evaluate the effect of foot manipulation on pregnancy-related pelvic girdle pain (PPGP) is feasible. A randomized, single-blind (patients and evaluators) pilot trial was performed to compare foot manipulation to a comparative group at 6-weekly treatment sessions at 5 physiotherapy outpatient clinics in Skaraborg primary care (Skövde, Sweden). Women at 12 to 31 weeks of pregnancy with well-defined PPGP (n = 97) and joint dysfunction or decreased range of movement in the feet were included. Women with a twin pregnancy, low back pain, rheumatoid arthritis, or other serious diseases and those who had previous foot manipulation were excluded. Visual analog scale scores were recorded before study start, before and after each treatment session, and 3 months after delivery. One-hundred and two women were eligible, and 97 were included (group 1: foot manipulation, n = 47; group 2: comparative treatment, n = 50); 40 and 36 in the foot manipulation and comparative treatment groups, respectively, completed the study. The foot manipulation group had a nonsignificant pain relief score compared with that of the comparative group, which had higher pain relief scores. The difference was most pronounced at the first and second treatment sessions. A power analysis showed that at least 250 individuals would be needed in each group to confirm the effect of foot manipulation. This study showed that it is feasible to assess the effect of foot manipulation on PPGP in a multicenter physical therapy outpatient clinic setting. A new larger study should choose a different comparative method and test this hypothesis in a full-scale trial.

Abdominal pain and shoulder tip pain after laparoscopic cholecystectomy are distressing for the patient. Various causes of this pain are peritoneal stretching and diaphragmatic irritation by high intra-abdominal pressure caused by pneumoperitoneum . We designed a study to compare the post operative pain after laparoscopic cholecystectomy at low pressure (7-8 mm of Hg) and standard pressure technique (12-14 mm of Hg). Aim : To compare the effect of low pressure and standard pressure pneumoperitoneum in post laparoscopic cholecystectomy pain . Further to study the safety of low pressure pneumoperitoneum in laparoscopic cholecystectomy. A prospective randomised double blind study. A prospective randomised double blind study was done in 100 ASA grade I & II patients. They were divided into two groups -50 each. Group A patients underwent laparoscopic cholecystectomy with low pressure pneumoperitoneum (7-8 mm Hg) while group B underwent laparoscopic cholecystectomy with standard pressure pneumoperitoneum (12-13 mm Hg). Both the groups were compared for pain intensity, analgesic requirement and complications. Demographic data and intraoperative complications were analysed using chi-square test. Frequency of pain, intensity of pain and analgesics consumption was compared by applying ANOVA test. Post-operative pain score was significantly less in low pressure group as compared to standard pressure group. Number of patients requiring rescue analgesic doses was more in standard pressure group . This was statistically significant. Also total analgesic consumption was more in standard pressure group. There was no difference in intraoperative complications. This study demonstrates the use of simple expedient of reducing the pressure of pneumoperitoneum to 8 mm results in reduction in both intensity and frequency of post-operative pain and hence early recovery and better outcome.This study also shows that low pressure technique is safe with comparable rate of intraoperative complications.

Infertility issues have been linked to the effect of oxidative reaction in the reproductive system. This study evaluated the effect of ascorbic acid, on fertility parameters of male albino Wistar rats was studied. Eighteen albino Wistar rats weighed between 178 g and 241 g were used, randomly assigned into three groups. Group 1 was the control group; oral gavaged 5 ml of distilled water; Groups 2 and 3 were administered medium dose (250 mg/kg) and high dose of ascorbic acid (400 mg/kg), respectively; twice daily for 21 days. Blood samples were obtained by cardiac puncture, and blood serum was obtained for hormonal assay, and the testes were harvested for sperm analysis. Follicle stimulating hormone levels significantly increased in the high-dose group as compared to both the control and medium dose groups. Luteinizing hormone levels in the medium dose group decreased significantly as compared to the control group. Testosterone significantly increased in both the medium- and high-dose groups as compared to the control group. Sperm motility increased significantly in the high-dose group as compared to both control and medium-dose groups. Percentage sperm concentration decreased significantly in the medium-dose group when compared to the control and increased significantly in the high-dose group as compared to the medium-dose group. For percentage normal morphology, there was a dose-dependent increase in the test groups when compared to control group. These results are indicative of a positive influence of ascorbic acid on male fertility modulators and may therefore, serve as a potential adjuvant treatment for male infertility cases.

In a large, multicenter, double-blind study of the effect of haloperidol and the atypical antipsychotic remoxipride on improvement of negative symptoms in schizophrenia, quality of life was also assessed using a modified version of the Sickness Impact Profile (SIP). Compared with previous studies, this study had a longer duration (28 weeks), and the dose of the comparator, haloperidol, was much lower. At the end of the study, compared with the baseline, both treatment groups reported comparable improvement in negative symptoms as defined by the protocol (at least 20% improvement). Similarly, both groups showed comparable changes on global and multidimensional self-assessments of quality of life. All the subfactors of the modified version of the SIP were similar in both groups, except for the subfactor that relates to alertness behavior, which possibly reflects remoxipride's lack of any sedating properties compared with haloperidol. This study presents an approach for inclusion of quality of life as an outcome measure in the design of clinical trials of new antipsychotic medications.

Purpose: The aim of this in vivo study was to compare the single-step border molding technique using injectable heavy viscosity addition silicone with sectional border molding technique using low fusing impression compound by evaluating the retention of heat cure trial denture bases. Materials and Methods: Ten completely edentulous patients in need of prostheses were included in this study. Two border molding techniques, single-step (Group 1) and sectional (Group 2), were compared for retention. Both border molding techniques were performed in each patient. In both techniques, definitive wash impression was made with light viscosity addition silicone. The final results were analyzed using paired t-test to determine whether significant differences existed between the groups. Results: The t-value (3.031) infers that there was a significant difference between Group 1 and Group 2 (P = 0.014). The retention obtained in Group 2 (mean = 9.05 kgf) was significantly higher than that of Group 1 (mean = 8.26 kgf). Conclusion: Sectional border molding technique proved to be more retentive as compared to single-step border molding although clinically the retention appeared comparable. PMID:27746597

Exposure to environmental hazards will destroy a number of ovarian primordial follicles, reduce ovarian reserve and subsequent reproductive ability. This study designed to evaluate ovarian parameters and ovarian blood flow of women living in the area of environmental crisis Shalkar city (Kazakhstan) compared to women living in Aktobe city (Kazakhstan). 220 women in their reproductive age studied and classified into two groups; study (Shalkar) group and control (Aktobe) group. Blood sample taken from studied women during follicular phase (day 3) for hormonal level evaluation including; follicle stimulating hormone (FSH) and anti-Mullerian hormone (AMH). Studied women evaluated using trans-vaginal ultrasound (TVS) to detect antral follicle count (AFC) during follicular scan and ovarian volume (OV), ovarian blood flow (OBF) using pulsatility index (PI) during follicular scan and luteal scan. Both ovaries AFC was significantly less in study (Shalkar) group compared to and control (Aktobe) group (p=0.0001). Mean ovarian volume was significantly less in Shalkar group in both follicular phase and luteal phase (5.86±0.23 and 6.19±0.22Cm(3); respectively) compared to Aktobe group (6.85±0.19 and 6.92±0.18Cm(3); respectively). In addition, mean ovarian pulsatility index was significantly high with subsequent decrease in ovarian blood flow in Shalkar group in both follicular phase and luteal phase (3.36±0.20 and 3.45±0.19Cm/s; respectively) compared to Aktobe group (2.96±0.16 and 2.92±0.15Cm/s; respectively). This study suggests definite environmental effect on ovarian parameters as indicated by decreased AFC, decreased both follicular and luteal OV and OBF in women living in environmental crisis Shalkar group compared to Aktobe group.

Sharma, Anupriya; Ramesh, Amitha; Thomas, Biju

2009-01-01

Background and Objectives: Circulating C-reactive protein (CRP) levels are a marker of systemic inflammation and are associated with periodontal disease, a chronic bacterial infection associated with elevation of proinflammatory cytokines and prostaglandins. CRP has been associated with adverse pregnancy outcomes, including preterm delivery, preeclampsia, and intrauterine growth restriction. Furthermore, periodontal disease has been associated with increased risk of preterm low birth weight, low birth weight, and preterm birth. The present study was conducted to assess plasma CRP levels in pregnant women with and without periodontal disease; to evaluate the effect of periodontal therapy on the incidence of preterm delivery; and to compare the incidence of preterm delivery in pregnant women with and without periodontal disease. Materials and Methods: A total of 90 pregnant women aged between 18-35 years with gestational age between 12-28 weeks were recruited and divided into three equal groups (control group, study group, treatment group) of 30 each. Blood samples were taken for estimation of C-reactive protein levels from all groups at 12-20 weeks of gestation, determined using ultrasensitive turbidimetric immunoassay (QUANTIA-CRP US). The treatment group comprised plaque control, scaling, and root planning and daily rinsing with 0.2% chlorhexidine mouth before 28 weeks of gestation. Results: The mean value of C-reactive protein levels in subjects with periodontal disease was higher compared to control group i.e., 1.20 ± 0.247 mg/dl and 1.22 ± 0.250 mg/dl, respectively, compared to 0.713 ± 0.139 mg/ dl (P = 0.001). The mean value of CRP levels before treatment was greater than the mean value after treatment i.e., 1.22 ± 0.25 compared to 0.84 ± 0.189 (P < 0.001). The incidence of preterm delivery (< 37 weeks) was 31.7% in the periodontal disease group (study group) compared to 8.3% in the control group (P = 0.001). The incidence of preterm delivery in the treatment group was 15.0% compared to 31.7% in the nontreatment group (study group). Conclusion: The findings from the study suggest that periodontal disease in pregnant women is associated with increased C- reactive protein levels in early pregnancy, incidence of preterm delivery is higher in pregnant women with periodontal disease compared to healthy controls, periodontal therapy during pregnancy reduces plasma CRP levels and there is decrease in incidence of preterm delivery after periodontal therapy.

The aim of this study was to analyze and compare the effects of tobacco on salivary pH between tobacco chewers, smokers and controls. A total of 60 subjects (males and females) aged 25-40 years, were divided equally into three groups: Tobacco smokers (Group A), chewers (Group B) and controls (Group C). Saliva of each subject was collected under resting condition. Salivary pH was determined using the specific salivary pH meter. The mean (±standard deviation) pH for Group A was 6.75 (±0.11), Group B was 6.5 (±0.29) and Group C was 7.00 (±0.28) after comparison. The significant results showed lower salivary pH in Groups A and B as compared to controls. Salivary pH was lowest in Group B compared to Group A and Group C. This study indicates that a lower (acidic) salivary pH was observed in tobacco users as compared with control. These alterations in pH due to the long-term effect of tobacco use can render oral mucosa vulnerable to various oral and dental diseases.

Introduction Smoking is a hazardous habit which causes definite changes in the oral cavity, consequently there exist changes in the mucosa when subjected to smoking. Palatal mucosa is first to be affected. The present study determines the palatal status in reverse smokers and conventional smokers. Aim To study and compare the clinical, cytological and histopathological changes in palatal mucosa among reverse and conventional smokers. Materials and Methods Study sample was categorized into two groups. Group 1 comprised of 20 subjects with the habit of reverse smoking and Group 2 comprised of 20 subjects with the habit of conventional smoking. Initially, clinical appearance of the palatal mucosa was recorded, followed by a cytological smear and biopsy of the involved area among all the subjects. The findings were studied clinically, the specimens were analysed cytologically and histopathologically, and compared among the two groups. Results The severity of clinical changes of the palatal mucosa among reverse smokers was statistically significant when compared to those of conventional smokers. There was no statistically significant difference observed in cytological staging between the groups with a p-value of 0.35. The histopathological changes in both the groups showed a significant difference with a p-value of 0.02. A significant positive correlation was observed between the clinical appearance, and cytological, histopathological changes. Conclusion Profound clinically aggressive changes were observed in group I compared to group II. Severity of dysplastic changes have been detected in few subjects through histopathological examination irrespective of no prominent clinical and cytological changes observed among the two groups.

Spasticity from the upper motor neuron syndrome can result from a variety of conditions affecting the cortex or spinal cord. Some of the more common conditions associated with spasticity include spinal cord injury, cerebral palsy, and post-stroke syndrome. In this study we compared the efficacy and safety of baclofen vs tolperisone in spasticity. One hundred fifty patients with cerebral palsy or post stroke or spinal cord injury associated spasticity were enrolled in present study. Group I comprised of Seventy-five patients receiving baclofen and group II comprised of 75 patients receiving tolperisone. For efficacy measurement 4 evaluation methods were used, 1) Modified Ashworth Scale for muscle tone, 2) Medical research council scale for muscle strength and 3) Barthel Index for functional outcome 4) Coefficient of efficacy. In efficacy evaluation, both groups showed significant improvement in muscle tone, muscle strength and functional outcome at week 6 (Group I, 1.55±0.053, 2.79+0.032, 59.31±1.32; Group II, 1.57±0.053, 3.04±0.032, 73±1.32 respectively). In between the group analysis, there was no significant difference in muscle tone improvement in both the groups after 6 weeks (Group I, 1.055±0.053 vs Group II, 1.57±0.053, p>0.05). Group II showed non-significant but greater improvement in muscle strength (Week 6; Group I, 2.79±0.032 vs Group II, 3.04±0.032, p>0.07). Improvement in functional outcomes was greater in group II as compared to group I (Group I, 59.31±1.32 vs Group II, 73±1.32, p<0.05). Overall efficacy coefficient was greater for group II (3.6) as compared to group I (2.3). Baclofen showed more side effects compared to tolperisone in, asthenia being the most frequent. Tolperisone offers greater improvement in activities of daily living compared to baclofen. Tolperisone is more tolerable drug as compared to baclofen. Copyright © 2017 Elsevier Masson SAS.

This study aims to investigate the effect of platelet-rich plasma (PRP) on femoral head osteonecrosis and compare it with bone marrow injection and core decompression. A total of 30 healthy, adult, male New Zealand white rabbits (mean weight 2.25±0.15 kg; range 2.0 to 2.5 kg) were used in the study. To create experimental osteonecrosis in all rabbits, 40 mg/kg methylprednisolone acetate was applied intramuscularly. Rabbits were randomly allocated into three groups with 10 rabbits in each: drilling group, PRP group, and bone marrow group. The non-drilled hips of the drilling group were identified as the control group. Rate of necrotic bone was lower in the PRP group compared to other groups. Highest rate of necrotic bone was detected in the control group. New bone formation rate was higher in the PRP group compared to other groups. Lowest new bone formation rate was determined in the control group. Inflammatory reaction rate was higher in the PRP group compared to other groups. Platelet-rich plasma injection may play a positive role in the treatment of steroid-associated osteonecrosis in a rabbit model.

Transdermal buprenorphine, which is used in chronic pain management, has rarely been studied for use in acute pain management. The aim of this study was to compare the safety and efficacy of transdermal buprenorphine patch to oral tramadol for post-operative analgesia, following proximal femur surgeries. Fifty adult patients undergoing surgery for hip fracture under spinal anaesthesia were included in this study. One group (Group TDB) received transdermal buprenorphine 10 mcg/h patch applied a day before the surgery and other group received oral tramadol 50 mg three times a day for analgesia (Group OT). They were allowed to take diclofenac and paracetamol tablets for rescue analgesia. Pain scores at rest, on movement, rescue analgesic requirement and side effects were compared between the groups over 7 days. Chi-square and independent sample t -test were used for categorical and continuous variables, respectively. Resting pain scores and pain on movement were significantly lower in TDB Group on all 7 days starting from 24 h post-operatively. Rescue analgesic requirement was significantly lower in TDB Group compared to OT Group. All the patients needed rescue analgesic in OT Group whereas 68% of the patients needed the same in TDB Group. Incidence of vomiting was less and satisfaction scores were much higher in TDB Group as compared to OT Group (79% vs. 66%, P < 0.001). Transdermal buprenorphine can be safely used for post-operative analgesia and is more efficacious in reducing post-operative pain after 24 hours, with fewer side effects when compared to oral tramadol.

Background: Relationships between in-vitro fertilization (IVF), gestational hypertension, and pregnancy outcomes are demonstrated in a number of studies. However, it is still debated if IVF treatment or specific characteristics of infertile patients are responsible for worse obstetrical and neonatal outcomes. Objective: The aim of this study was to investigate maternal characteristics associated with hypertensive disorders (HD) in IVF conceived pregnancies and to assess the obstetrical and neonatal outcomes. Materials and Methods: In this observational, cross-sectional study, 207 pregnant women who underwent IVF treatment were consecutively divided into two groups: a group that had no HD during pregnancy (IVF group) and a group that had HD during pregnancy (IVF+HD group). Maternal, obstetrical and neonatal data of the two groups were compared. Results: Some maternal characteristics were significantly higher in IVF+HD compared to IVF group such as: older age (p=0.0001), primiparity (p=0.038), obesity (p=0.0001), and cigarette smoking (p=0.0001). There were no significant differences between the groups in regard to obstetrical outcomes besides premature rupture of membranes time that was significantly higher in IVF+HD group compared to IVF group (p=0.036). In regard to neonatal outcomes, the only statistically significant difference was in the 5th min Apgar score, which was higher in IVF+HD group compared to IVF group without HD (p=0.002). Conclusion: With regard to significantly higher differences in maternal characteristics of IVF conceived pregnancies complicated with HD, compared to uncomplicated ones, development of a specific national prevention measure for HD of IVF conceived pregnancies in Kosovo is strongly suggested. In addition, setting up of a national registry is recommended in order to evaluate the outcomes of IVF treatments properly. PMID:29675491

2016-09-01

This study sought to answer the following questions: What are the outcomes of physiotherapy post lumbar total disc replacement (LTDR) compared with patient self-mediated rehabilitation? Is a difference in outcomes related to the number of physiotherapy sessions? This is a retrospective observational study of 600 patients post TDR. Patient outcomes for self-mediated rehabilitation (Group 1), 1-3 sessions of clinic-based physiotherapy (Group 2) and ≥4 sessions of clinic-based physiotherapy (Group 3) were analysed. Outcomes measures included the Oswestry Disability Index (ODI), Roland Morris Disability Questionnaire (RMQ), Short Form-36 Physical (SF-36 PCS) and Mental Subscale Components (SF-36 MCS), Visual Analogue Scale (VAS) for back and leg pain intensity. Patient's pre-operative baseline measures and post-operative follow-up measures at 3, 6, 12 and 24 months post-operatively were analysed. Oswestry Disability Index and RMQ had significantly lower scores in Group 3 compared with Group 1 at 3, 6, 12 and 24 months follow-up. Significantly lower scores for Group 2 compared with Group 1 were observed for the ODI at 3 months follow-up and for the RMQ at 3 and 6 months follow-up. Significantly lower scores were observed in Group 3 compared with Group 1 for VAS back pain at 3 months and VAS leg pain at 6 months follow-up. Significantly higher scores in Group 3 compared with Group 1 were also observed in the SF-36 PCS at 6, 12 and 24 months. Significantly higher scores in Group 2 compared with Group 1 were observed at 6 months follow up. These trends were also observed when investigating the percentage of patients with a greater 50% improvement in the outcome measure. Physiotherapy post-LTDR produces statistically significant and possibly clinically important improvements in functional disability, pain and quality of life outcomes compared with self-mediated rehabilitation.

In this study, we aimed to compare the effects of dexpanthenol and N-acetylcysteine on wound healing. The wound healing process is a multifaceted sequence of activities associated with tissue restoration process. A number of investigations and clinical studies have been performed to determine new approaches for the improvement of wound healing. A total of 30 rats were divided into 3 equal groups. A linear 2-cm incision was made in the rats' skin. No treatment was administered in the first (control) group. Dexpanthenol cream was administered to the rats in the second group and 3% N-acetylcysteine cream was administered to the rats in the third group. The wound areas of all of the rats were measured on certain days. On the 21st day, all wounds were excised and histologically evaluated. The epithelialization and granulation rates between the groups were revealed to be similar in microscopic evaluations. Although the fibrosis was remarkable in the control group as compared with the other groups, it was similar in N-acetylcysteine and dexpanthenol groups. Angiogenesis rate was remarkable in the N-acetylcysteine group compared with the others. In multiple-comparison analysis, Dexpanthenol and N-acetylcysteine groups had similar results in terms of wound healing rates (P < 0.05), which were both higher than in the control group (P > 0.05). The efficacy of N-acetylcysteine in wound healing is comparable to dexpanthenol, and both substances can be used to improve wound healing.

This study explored effects of exposure to maternal voice on short-term outcomes in very low birth weight preterm infants cared for within an neonatal intensive care unit (NICU) without an ongoing program of developmental care. Using a comparative design, 53 infants born during their 27th to 28th postmenstrual week were sampled by convenience. Experimental groups were exposed to maternal voice during two developmental time periods. Group 1 listened to a recording of their mothers reciting a rhyme from 28 to 34 postmenstrual weeks. Group 2 waited 4 weeks and heard the recording from 32 to 34 weeks. The control group received routine care. The primary analysis of combined experimental groups compared to the control group revealed that the experimental infants experienced significantly fewer episodes of feeding intolerance and achieved full enteral feeds quicker compared to the control group. Further, in an analysis evaluating all three groups separately, it was noted that Group 1 experienced significantly fewer episodes of feeding intolerance compared to the control group. Study findings warrant further investigation of exposure to maternal voice and the developmental timing at which exposure is begun. PMID:20112262

To determine the effect of oral omega-3 fatty acid (ω3FA) supplementation in laser in situ keratomileusis (LASIK)-associated dry eye. In this prospective, open-label study, patients undergoing LASIK were randomized to receive either 1.2 g/d of a triglyceride formulation of oral ω3FA (treatment group) or 400 mg/d vitamin E (control group) for 1 week before and continued for 12 weeks after surgery. Ocular surface disease index, tear breakup time, ocular surface staining, and Schirmer scores were evaluated and compared preoperatively and at 3 months after LASIK. The study included 30 patients in each group. All parameters were comparable at baseline. Ocular surface disease index scores increased comparably in both groups (1.9 ± 0.6 increase in the treatment group; 2.8 ± 0.5 in the control group) (P = 0.267). Compared with baseline levels, tear breakup time decreased significantly (P < 0.01) but comparably in both treatment (-2.3 ± 0.4 seconds decrease) and control (-3.5 ± 0.7 seconds decrease) groups (P = 0.105). More eyes in the control group (43.4%) had conjunctival staining with Lissamine green at 3 months compared with the treatment group (14%) (P = 0.009). The Schirmer score at 3 months was higher (P = 0.003) in the treatment group (30.5 ± 0.90 mm) than in the control group (25.7 ± 1.3 mm) with a increase of 5.9 ± 1.3 mm from baseline in the treatment group and a decrease of 1.5 ± 1.2 mm in the control group. Supplementation with ω3FA in patients undergoing LASIK had a positive influence on tear secretion, whereas tear film stability remained unaffected when compared with the control group.

The effect of mobile phone radiation on human reproduction system is still a matter of debate. In this study, 18 male rabbits were randomly divided into two experimental groups and one control group. Experimental groups received simulated microwaves with the frequency of 950 MHz and the output power of 3 and 6 watts for 2 weeks, 2 h a day. After a week of rest, the microscopic slides from the quada of the excised epididymis were prepared. Then, the diameter of epididymis, the height of epithelium and the number of apoptotic cells in epithelium in study groups were determined. The data were compared using spss software and one-way anova test. The epithelial height and diameter of the epididymis in 3 watt and 6 watt groups had a significant decrease compared to the control group (P < 0.001), while the testosterone level only in 6 watt group was significantly decreased compared to control group. The rate of apoptosis in the epithelial cells of the epididymis had a significant increase only in 6 watt group compared to the control group (P < 0.001). This study showed that the microwaves with the frequency of 950 MHz can have negative impacts on morphometric and apoptotic changes of rabbit epididymis. © 2014 Blackwell Verlag GmbH.

Survival rates for women with a diagnosis of breast cancer continue to improve. However, some women may experience physical, psychological and emotional effects post diagnosis, throughout treatment and beyond. Support groups can provide opportunities for people to share their experiences and learn from others. As the number of online support groups increases, more and more women with breast cancer will likely access them. To assess effects of online support groups on the emotional distress, uncertainty, anxiety, depression and quality of life (QoL) of women with breast cancer. We searched for trials in the Cochrane Breast Cancer Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 4), MEDLINE, Embase and PsycINFO on 2 May 2016, and we handsearched journals and reference lists. We also searched the World Health Organization's International Clinical Trials Registry Platform (WHO ICTRP) search portal and clinicaltrials.gov on 2 May 2016. We included randomised controlled trials (RCTs) assessing effects of online support groups on women with a diagnosis of breast cancer and women who have completed breast cancer treatment. We included studies comparing online support groups with a usual care group, and studies comparing two or more types of online support groups (without a usual care group). Two review authors independently extracted data and assessed risk of bias. We presented outcome data using mean differences (MDs) and standardised mean differences (SMDs) along with 95% confidence intervals (CIs), and we used the fixed-effect model when appropriate. We assessed the quality of the body of evidence using the GRADE approach. We included six studies (492 women) that assessed online support groups for women with breast cancer. Online support groups in these six trials lasted from six to 30 weeks. Women participated in these groups between 1.5 and 2.5 hours per week, and investigators conducted all studies in the USA. Participants were predominantly white and well educated and were moderate to high earners. Four studies compared an online support group versus a control group, and the other two compared a 'moderated' versus a 'peer-led' online support group, and a 'standard' versus an 'enhanced' online support group, respectively.None of the included studies measured 'emotional distress' or uncertainty. One study (78 women) for which data for analysis were missing reported no positive effects of online support on 'distress' and 'cancer-specific distress' versus support provided by a control group. Two studies measured anxiety: One study (72 women) found no difference in anxiety at the end of the intervention between the online support group and the control group (MD -0.40, 95% CI -6.42 to 5.62; low-quality evidence), and the second study (184 women) reported a reduction in anxiety levels at the end of the intervention when comparing the 'standard' support group (run by participants without prompting from health professionals) versus an 'enhanced' online support group (in which participants were specifically asked by the researcher to respond to one another's need for support).Five studies (414 women) measured depression. Three studies compared depression in the online support group with depression in the control group. Pooled data from two studies (120 women) showed a small to moderate reduction in depression in the online support group compared with control groups at the end of the intervention (SMD -0.37, 95% CI -0.75 to 0.00; very low-quality evidence). The third study, a pilot study (30 women), provided no data for analysis but reported no difference in depression between participants in support and control groups at the end of the intervention. Of the remaining two studies that measured depression, one study (60 women) provided no extractable data for comparison but reported no difference in depressive symptoms between a 'moderated' and a 'peer-led' support group; the other study (184 women) reported greater reduction in depression in the 'standard' support group than in the 'enhanced' online support group.Three studies measured quality of life. One pilot study (30 women) provided limited data for analysis but reported no change in quality of life at the end of the intervention. Only two studies (140 women) provided data for pooling and showed no positive effects on quality of life at four months post intervention compared with controls (SMD -0.11, 95% CI -0.47 to 0.24; very low-quality evidence). At 12 months post intervention, one study (78 women) reported that the intervention group did not attain better quality of life scores than the control group (MD -10.89, 95% CI -20.41 to -1.37; low-quality evidence).We found no data for subgroup analyses on stage of disease, treatment modality and types and doses of interventions. No studies measured adverse effects. This review did not find the evidence required to show whether participation in online support groups was beneficial for women with breast cancer, because identified trials were small and of low or very low quality. Large, rigorous trials with ethnically and economically diverse participants are needed to provide robust evidence regarding the psychosocial outcomes selected for this review.

No evidence exists from randomized trials to support using cloud-based manometers integrated with available physician order entry systems for tracking patient blood pressure (BP) to assist in the control of renal function deterioration. We investigated how integrating cloud-based manometers with physician order entry systems benefits our outpatient chronic kidney disease patients compared with typical BP tracking systems. We randomly assigned 36 chronic kidney disease patients to use cloud-based manometers integrated with physician order entry systems or typical BP recording sheets, and followed the patients for 6 months. The composite outcome was that the patients saw improvement both in BP and renal function. We compared the systolic and diastolic BP (SBP and DBP), and renal function of our patients at 0 months, 3 months, and 6 months after using the integrated manometers and typical BP monitoring sheets. Nighttime SBP and DBP were significantly lower in the study group compared with the control group. Serum creatinine level in the study group improved significantly compared with the control group after the end of Month 6 (2.83 ± 2.0 vs. 4.38 ± 3.0, p = 0.018). Proteinuria improved nonsignificantly in Month 6 in the study group compared with the control group (1.05 ± 0.9 vs. 1.90 ± 1.3, p = 0.09). Both SBP and DBP during the nighttime hours improved significantly in the study group compared with the baseline. In pre-end-stage renal disease patients, regularly monitoring BP by integrating cloud-based manometers appears to result in a significant decrease in creatinine and improvement in nighttime BP control. Estimated glomerular filtration rate and proteinuria were found to be improved nonsignificantly, and thus, larger population and longer follow-up studies may be needed.

Breastfeeding or breast milk for procedural pain in neonates.

Physiological changes brought about by pain may contribute to the development of morbidity in neonates. Clinical studies have shown reduction in the changes in physiological parameters and pain score measurements following pre-emptive analgesic administration in situations where the neonate is experiencing pain or stress. Nonpharmacological measures (such as holding, swaddling, breastfeeding) and pharmacological measures (such as acetaminophen, sucrose and opioids) have been used for this purpose. The primary objective of this review was to evaluate the effectiveness of breastfeeding or supplemental breast milk in reducing procedural pain in neonates. The secondary objective was to conduct subgroup analyses based on the type of control intervention, type of painful procedure, gestational age and the amount of supplemental breast milk given. A literature search was performed using MEDLINE (1966 - Feb 2006), EMBASE (1980 - Feb 2006), CINAHL (1982 - Feb 2006), Cochrane Central Register of Controlled Trials (Issue 4, 2005 of Cochrane Library), abstracts from the annual meetings of the Society for Pediatric Research (1994 - 2006) and major pediatric pain conference proceedings. No language restrictions were applied. Randomized or quasi-randomized controlled trials of breastfeeding or supplemental breast milk versus no treatment/other measures in neonates were eligible for inclusion in this review. The study must have reported on either physiologic markers of pain or validated pain scores. The methodological quality of the trials was assessed using the information provided in the studies and by personal communication with the authors. Data on relevant outcomes were extracted and the effect size was estimated and reported as relative risk (RR), risk difference (RD) and weighted mean difference (MD) as appropriate. Eleven eligible studies were identified. Marked heterogeneity in terms of control intervention and pain assessment measures were noted among the studies. Neonates in the breastfeeding group had statistically significantly less increase in the heart rate, reduced proportion of crying time and reduced duration of crying compared to swaddled group or pacifier group. Neonates in the breastfeeding group had a significant reduction in duration of crying compared to fasting (no intervention) group, but there was no significant difference when compared to glucose group. Premature Infant Pain Profile scores were significantly different between the breastfeeding group when compared to placebo group and the group positioned in mother's arms. However, these scores were not statistically significantly different in the breastfeeding group when compared to the no treatment group and the glucose group. Douleur Aigue Nouveau-ne scores were significantly different in the breastfeeding group when compared to the placebo group and the group positioned in mother's arms, but not when compared to the glucose group. Neonates in the supplemental breast milk group had significantly less increase in the heart rate and Neonatal Facial Coding Score compared to the placebo group. The differences in the duration of crying time and oxygen saturation change between supplemental breast milk group and the placebo group were not statistically significant. Neonates in the supplemental breast milk group had significantly higher increase in the heart rate changes and duration of crying time compared to glucose/sucrose group. No study was identified that has evaluated safety/effectiveness of repeated administration of breastfeeding or supplemental breast milk for pain relief. If available, breastfeeding or breast milk should be used to alleviate procedural pain in neonates undergoing a single painful procedure compared to placebo, positioning or no intervention. Administration of glucose/sucrose had similar effectiveness as breastfeeding for reducing pain. The effectiveness of breast milk for repeated painful procedures is not established and further research is needed. These studies should include various control interventions including glucose/ sucrose and should target preterm neonates.

The aim of this study was to evaluate the effects of IMUNO-2865(®) on hematological and antioxidative parameters in sea bream. Total of 640 sea bream were fed with diets containing 0 (Group 1), 1 (Group 2), 10 (Group 3) and 25 (Group 4) g of IMUNO-2865(®) kg(-1) feed during 90 days. Samples were taken each month and three months after the supplementation. A significant heterophils increase was observed in group 4 compared to group 1 after two months, and an increase in monocytes number was observed in group 4 compared to the other groups after one month. Glutathione peroxidase (GSH-Px) and paraoxonase-1 (PON1) were significantly increased in groups 3 and 4 compared to the control group three months into the experiment. Superoxide dismutase (SOD) was increased in group 4 compared to the control group from day 60 until the end of the experiment, and in groups 2 and 3 compared to the control after three months. Based on the differences in the cellular immunity and oxidative stress parameters, with an overall absence of mortality, the results of this study suggest that the use of IMUNO-2865(®) in aquaculture is safe and possess a cumulative immunostimulatory effect on sea bream.

Dunbar, Nancy M; Yazer, Mark H

Use of universally ABO-compatible group AB plasma for trauma resuscitation can be challenging due to supply limitations. Many centers are now using group A plasma during the initial resuscitation of traumatically injured patients. This study was undertaken to evaluate the impact of this practice on mortality and hospital length of stay (LOS). Seventeen trauma centers using group A plasma in trauma patients of unknown ABO group participated in this study. Eligible patients were group A, B, and AB trauma patients who received at least 1 unit of group A plasma. Data collected included patient sex, age, mechanism of injury, Trauma Injury Severity Score (TRISS) probability of survival, and number of blood products transfused. The main outcome of this study was in-hospital mortality differences between group B and AB patients compared to group A patients. Data on early mortality (≤24 hr) and hospital LOS were also collected. There were 354 B and AB patients and 809 A patients. The two study groups were comparable in terms of age, sex, TRISS probability of survival, and total number of blood products transfused. The use of group A plasma during the initial resuscitation of traumatically injured patients of unknown ABO group was not associated with increased in-hospital mortality, early mortality, or hospital LOS for group B and AB patients compared to group A patients. These results support the practice of issuing thawed group A plasma for the initial resuscitation of trauma patients of unknown ABO group. © 2017 AABB.

The aim of the present study was to assess possible effects on mental and physical well-being and stress-related biological markers of a web-based health promotion tool. A randomized, prospectively controlled study was conducted with before and after measurements, involving 303 employees (187 men and 116 women, age 23-64) from four information technology and two media companies. Half of the participants were offered web-based health promotion and stress management training (intervention) lasting for six months. All other participants constituted the reference group. Different biological markers were measured to detect possible physiological changes. After six months the intervention group had improved statistically significantly compared to the reference group on ratings of ability to manage stress, sleep quality, mental energy, concentration ability and social support. The anabolic hormone dehydroepiandosterone sulphate (DHEA-S) decreased significantly in the reference group as compared to unchanged levels in the intervention group. Neuropeptide Y (NPY) increased significantly in the intervention group compared to the reference group. Chromogranin A (CgA) decreased significantly in the intervention group as compared to the reference group. Tumour necrosis factor alpha (TNFalpha) decreased significantly in the reference group compared to the intervention group. Logistic regression analysis revealed that group (intervention vs. reference) remained a significant factor in five out of nine predictive models. The results indicate that an automatic web-based system might have short-term beneficial physiological and psychological effects and thus might be an opportunity in counteracting some clinically relevant and common stress and health issues of today.

Despite its widespread support, the most effective simulation-based debriefing method has little evidence to support its efficacy. In this study, we compared the effect of peer-led and instructor-led debriefing among nursing students. The study was conducted with a non-equivalent control group using a pretest-post-test design. A convenience sample of third-year nursing students was used for the study, where 65 students enrolled in a 2-week clinical placement rotation were randomly assigned to the instructor-led group or peer-led group. The quality of cardiopulmonary resuscitation skills, satisfaction with simulation, and quality of debriefing in the peer-led group were compared to those in the instructor-led group. Group differences at each testing interval were analyzed using independent t-test. Nursing students in the instructor-led debriefing group showed better subsequent cardiopulmonary resuscitation performance, more satisfaction with simulation experience, and higher debriefing scores compared to the peer-led group. From our study, instructor-led debriefing is an effective method in improving skills performance, inducing favorable satisfaction, and providing better quality of debriefing among nursing students. © 2016 John Wiley & Sons Australia, Ltd.

Previous studies have demonstrated an increase in surgical morbidity, mortality, duration of stay, and costs in teaching hospitals. These studies are confounded by many variables. Controlling for these variables, we studied the effect of surgical residents on these outcomes during rotations with non-academic-based teaching faculty at a teaching hospital. Patients received care at a single teaching hospital from a group of 8 surgeons. Four surgeons did not have resident coverage (group 1) and the other 4 had coverage (group 2). Continuous severity adjusted complications, mortality, length of stay, cost, and hospital margin data were collected and compared. Five common procedures were examined: bowel resection, laparoscopic cholecystectomy, hernia, mastectomy, and appendectomy. Comparing all procedures together, there were no differences in complications between the groups, although there was greater mortality, a greater duration of stay, and higher costs in group 2. When comparing the 5 most common procedures individually, there was no difference in complications or mortality, although a greater length of stay and higher costs in group 2. Comparing the most common procedures performed individually, patients cared for by surgeons with surgical residents at a teaching hospital have an increase in duration of stay and cost, although no difference in complications or mortality compared to surgeons without residents.

The utility of mechanical bowel preparation (MBP) to minimize infectious complications in elective colorectal surgery is contentious. Though data is scarce in children, adult studies suggest a benefit to MBP when administered with oral antibiotics (OAB). After IRB approval, the Pediatric Health Information System (PHIS) was queried for young children undergoing elective colon surgery from 2011 to 2014. Patients were divided into: no bowel preparation (Group 1), MBP (Group 2), and MBP plus OAB (Group 3). Statistical significance was determined using univariate and multivariate analysis with GEE models accounting for clustering by hospital. One thousand five hundred eighty-one patients met study criteria: 63.7% in Group 1, 27.1% in Group 2, and 9.2% in Group 3. Surgical complication rate was higher in Group 1 (23.3%) compared to Groups 2 and 3 (14.2% and 15.5%; P<0.001). However, median length of stay was shorter in Group 1 (4, IQR 4days) compared to Group 2 (5, IQR 3) and Group 3 (6, IQR 3) (P<0.001). 30-day readmission rates were similar. In multivariate analysis compared to patients in Group 1, the odds of surgical complications were 0.72 (95% CI 0.40-1.29, P=0.28) with MBP alone (Group 2), 1.79 (95% CI 1.28-2.52, P=0.0008) with MBP+OAB (Group 3), and 1.13 (95% CI 0.81-1.58, P=0.46) for the aggregate Group 2 plus 3. Utilization of bowel preparation in children is variable across children's hospitals nationally, and the benefit is unclear. Given the discrepancy with adult literature, a three-armed pediatric-specific randomized controlled trial is warranted. Level III treatment study - retrospective comparative study.

Tunneled hemodialysis catheters become essential in dialysis access when there is no possibility of using a functioning arteriovenous fistula. Collateral or occluded veins visible on ultrasound are used for puncture and passage of catheters into the central venous system. Chronically occluded veins are crossed with guidewires to allow dilatation and subsequent passage of hemodialysis catheters. We performed a retrospective analysis of patient demographics, comorbidities, procedural complications, functional survival, performance, and history of previous vascular access. The study group was compared with two control groups in which dialysis catheters were inserted either by radiologists in the interventional suite or by clinicians on the wards. Nineteen patients from the study group were compared with same number of patients in both control groups. The mean age of the study group was higher compared with the control groups. There was no significant difference in mean functional survival, infection rates, dialysis pump speeds in the first 2 weeks, and procedural complications between the study group and the controls. The study group had a significantly higher number of previous vascular access interventions, longer dialysis careers, and more comorbidities. Tunneled dialysis catheter placement by way of collateral or occluded veins appears safe and effective. These techniques give the operator further options when faced with patients possessing challenging vascular access. Indeed, there may be a case for preferential use of these veins to keep patent central veins in reserve.

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

This study aimed to compare the effects of relaxation techniques on fatigue in hemodialysis patients. This clinical trial study was conducted on 105 hemodialysis patients. The subjects were categorized into three groups as: relaxation, aromatherapy and control. In the relaxation group, Benson muscle relaxation techniques were employed; in the aromatherapy group, the inhalation of two drops of 5% lavender essential oil used and the control group only received regular healthcare actions. Data collected by using brief fatigue inventory, before and after the intervention. Results of the current study indicated significant differences in the mean of changes in fatigue scores before and after the intervention between the relaxation and aromatherapy groups, but the difference was insignificant in the control group. Aromatherapy with lavender essential oil can decrease the level of fatigue in the patients undergoing hemodialysis compared to Benson relaxation techniques. Copyright © 2018 Elsevier Ltd.

The objective of the present study was to evaluate the toxic effects of aflatoxin on some hematological parameters and to determine the preventive effectiveness of added glucomannan. In the study, 32 Merino rams were used, and the rams were separated equally to four groups as control (C), glucomannan (G), glucomannan + aflatoxin (AG), and aflatoxin (A). Erythrocyte, leukocyte count, hemoglobin, and hematocrit levels were decreased in A group compared with the other groups, and there was a reduction in similar parameters in AG group compared to control values. On the other hand, these parameters were tended to increase in AG group compared to A group values. Aflatoxicosis caused the lymphocytopenia and monocytopenia but increased percentage of neutrophil counts. In conclusion, the results determined in the study might be important to demonstrate the effects of aflatoxicosis and glucomannan on some haematological parameters before the clinical symptoms appear.

The aim of the current study was to investigate whether intestinal ischemic preconditioning (IP) reduces damage to the liver during hepatic ischemia reperfusion (IR). Sprague Dawley rats were used to model liver IR injury, and were divided into the sham operation group (SO), IR group and IP group. The results indicated that IR significantly increased Bax, caspase 3 and NF-κBp65 expression levels, with reduced expression of Bcl-2 compared with the IP group. Compared with the IR group, the levels of AST, ALT, MPO, MDA, TNF-α and IL-1 were significantly reduced in the IP group. Immunohistochemistry for Bcl-2 and Bax indicated that Bcl-2 expression in the IP group was significantly increased compared with the IR group. In addition, IP reduced Bax expression compared with the IR group. The average liver injury was worsened in the IR group and improved in the IP group, as indicated by the morphological evaluation of liver tissues. The present study suggested that IP may alleviates apoptosis, reduce the release of pro-inflammatory cytokines, ameloriate reductions in liver function and reduce liver tissue injury. To conclude, IP provided protection against hepatic IR injury. PMID:26821057

2018-01-01

It is a well-known fact that severe pregnancy-induced hypertension (PIH) can be disastrous at times as it can cause a lot of complications to both pregnant women and her baby. Hence, it is always desirable to know the extent of severity by a real-time and easily accessible modality like ultrasound. The aim of the study was to evaluate the incidence of raised intracranial pressure (ICP) in severe preeclampsia and eclampsia patients using ocular ultrasonography with optic nerve sheath diameter (ONSD) measurement. This study design was a prospective and clinically controlled blinded observational study. After taking necessary permissions from the Institution Ethical Committee, 75 patients were enrolled for the study. However, finally, 25 patients in severe preeclampsia and 24 in eclampsia group were compared with 25 normal term antenatal women. Demographic profiles, hemodynamic parameters, laboratory markers for severity of PIH, and ultrasonographic OSND were measured. They were statistically analyzed and compared using one-way ANOVA and Tukey's test. Value of P < 0.05 was considered statistically significant. All the three groups were comparable in terms of age, body weight, gestation age, gestity, and the number of primigravida in each group. There was a significant difference ( P < 0.05) in mean levels of hepatic aminotransferase levels and platelet counts between groups. Aspartate transaminase and alanine transaminase levels were much higher in Group II and III as compared to Group I, while platelet levels were lower in study groups indicating increase in severity of PIH. There was also a significant difference for systolic blood pressure and diastolic blood pressure ( P < 0.001) as both were significantly higher in study groups. Among severe PIH groups (Group II and III), the difference was comparable. OSND is a surrogate marker for raised ICP in severe PIH patients. It is a rapid, bedside, noninvasive, and readily accessible tool and could be a part of a holistic approach for managing such patients.

Helicobacter pylori (H. pylori) gastric infection is a main cause of inflammatory changes and gastric cancers. The aim of this study was finding the effects of curcumin on oxidative stress and histological changes in chronic gastritis associated with H. pylori. In a randomized clinical trial, patients were divided into two groups: a standard triple therapy group and triple therapy with curcumin group. Endoscopic and histological examinations were measured for all patients before and after 8 weeks. Triple therapy with curcumin treatment group significantly decreased malondialdehyde markers, glutathione peroxides and increased total antioxidant capacity of the gastric mucosa at the end of study compared to baseline and triple regimen groups. In addition, the oxidative damage to DNA was significantly decreased in triple therapy with curcumin group at the end of study compared to baseline and compared to triple therapy (P<0.05 for both). Triple therapy group in combination with Curcumin significantly decreased all active, chronic and endoscopic inflammation scores of patients compared to the baseline and triple therapy group (P<0.05 for both). The eradication rate by triple therapy + curcumin was significantly increased compared to triple therapy alone (P<0.05). Curcumin can be a useful supplement to improve chronic inflammation and prevention of carcinogenic changes in patients with chronic gastritis associated by H. pylori.

Endodontic infections require effective removal of microorganisms from the root canal system for long-term prognosis. Sodium hypochlorite (NaOCl) is the most effective irrigant currently, but potential complications due to its toxicity warrant search for newer alternatives. In this study, the antimicrobial efficacy of Morinda citrifolia (MC), green tea polyphenols and Triphala was compared with 5% NaOCl against Enterococcus faecalis . In this in vitro study sixty extracted human premolar teeth were infected with E. faecalis , a Group D Streptococci for 48 h. At the end of 48 h, the vital bacterial population was assessed by counting the number of colony-forming units (CFUs) on blood agar plate. Samples were divided into five groups; Group I (distilled water), Group II (NaOCl), Group III (MC), Group IV (Triphala), and Group V (green tea polyphenols). The samples were irrigated with individual test agents and CFUs were recorded. Kruskal-Wallis test was performed as the parametric test to compare different groups. Student's t -test was used to compare mean values between groups before and after treatment with test agents ( P < 0.001). NaOCl was the most effective irrigant the elimination of E. faecalis reinforcing its role as the best irrigant available currently and a gold standard for comparison of the experimental groups. Its antibacterial effect was comparable to Triphala. Among the experimental groups, MC showed the minimum antibacterial effect. The use of herbal alternatives as a root canal irrigant might prove to be advantageous considering the several undesirable characteristics of NaOCl.

Background Childbearing for the first time is a unique experience. Quality of life is an important indicator in health studies. This study aimed to assess the quality of life of women who were conceived by ARTs and had successful childbirth for the first time and to compare it with quality of life in women who become pregnant naturally and similarly had successful childbirth for the first time. Materials and Methods This was a cross sectional comparative study. The accessible sam- ple was recruited from patients attending an infertility clinic and two obstetric and gynecology clinics in Tehran, Iran, during March 2010 to March 2011. In all 276 patients were approached. Of these, 162 women (76 women in natural conception group and 86 women in assisted reproduction technologies group) who met the inclusion criteria were entered into the study. Quality of life was assessed using the 36-item Short Form Health Survey (SF-36). Women completed the questionnaire at two time points: i. last trimester and ii. first month after delivery. Comparison was made between two groups using Mann-Whitney U test and paired samples t test. Results Comparing the SF-36 scores between women in natural conception group and ARTs group before childbirth, it was found that natural group had better condition on physical functioning, role limitation due to physical problems, bodily pain and social functioning, while the ARTs group reported better status on general health, vitality, role limitation due to emotional problems, and mental health. However, after childbirth, the ARTs group reported a better condition almost on all measures, except for physical functioning. Comparing differences in obtained scores between two groups before and after childbirth, the results showed that improvements in health related quality of life measures for the ARTs group were greater in all measures, expect for general health. Conclusion The findings from this study suggest that health-related quality of life was improved in women who became a mother for the first time by either method. Comparing to women who became mother by natural conception, women who received ARTs showed better quality of life from this first successful experience. PMID:25083182

Background: Abdominal pain and shoulder tip pain after laparoscopic cholecystectomy are distressing for the patient. Various causes of this pain are peritoneal stretching and diaphragmatic irritation by high intra-abdominal pressure caused by pneumoperitoneum . We designed a study to compare the post operative pain after laparoscopic cholecystectomy at low pressure (7-8 mm of Hg) and standard pressure technique (12-14 mm of Hg). Aim : To compare the effect of low pressure and standard pressure pneumoperitoneum in post laparoscopic cholecystectomy pain . Further to study the safety of low pressure pneumoperitoneum in laparoscopic cholecystectomy. Settings and Design: A prospective randomised double blind study. Materials and Methods: A prospective randomised double blind study was done in 100 ASA grade I & II patients. They were divided into two groups -50 each. Group A patients underwent laparoscopic cholecystectomy with low pressure pneumoperitoneum (7-8 mm Hg) while group B underwent laparoscopic cholecystectomy with standard pressure pneumoperitoneum (12-13 mm Hg). Both the groups were compared for pain intensity, analgesic requirement and complications. Statistical Analysis: Demographic data and intraoperative complications were analysed using chi-square test. Frequency of pain, intensity of pain and analgesics consumption was compared by applying ANOVA test. Results: Post-operative pain score was significantly less in low pressure group as compared to standard pressure group. Number of patients requiring rescue analgesic doses was more in standard pressure group . This was statistically significant. Also total analgesic consumption was more in standard pressure group. There was no difference in intraoperative complications. Conclusion: This study demonstrates the use of simple expedient of reducing the pressure of pneumoperitoneum to 8 mm results in reduction in both intensity and frequency of post-operative pain and hence early recovery and better outcome.This study also shows that low pressure technique is safe with comparable rate of intraoperative complications.

Physiological changes brought about by pain may contribute to the development of morbidity in neonates. Clinical studies have shown reduction in changes in physiological parameters and pain score measurements following pre-emptive analgesic administration in situations where the neonate is experiencing pain or stress. Non-pharmacological measures (such as holding, swaddling and breastfeeding) and pharmacological measures (such as acetaminophen, sucrose and opioids) have been used for this purpose. The primary objective was to evaluate the effectiveness of breastfeeding or supplemental breast milk in reducing procedural pain in neonates. The secondary objective was to conduct subgroup analyses based on the type of control intervention, gestational age and the amount of supplemental breast milk given. We performed a literature search using the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 10), MEDLINE (1966 to February 2011), EMBASE (1980 to February 2011), CINAHL (1982 to February 2011), abstracts from the annual meetings of the Society for Pediatric Research (1994 to 2011), and major paediatric pain conference proceedings. We did not apply any language restrictions. Randomised controlled trials (RCTs) or quasi-RCTs of breastfeeding or supplemental breast milk versus no treatment/other measures in neonates were eligible for inclusion in this review. The study must have reported on either physiologic markers of pain or validated pain scores. We assessed the methodological quality of the trials using the information provided in the studies and by personal communication with the authors. We extracted data on relevant outcomes, estimated the effect size and reported this as a risk ratio (RR), risk difference (RD) and weighted mean difference (MD) as appropriate. Of twenty eligible studies, ten evaluated breastfeeding and ten evaluated supplemental breast milk. Sixteen studies analysed used heel lance and four used venepuncture as procedure. We noted marked heterogeneity in control intervention and pain assessment measures among the studies. Neonates in the breastfeeding group had statistically a significantly lower increase in heart rate, reduced proportion of crying time and reduced duration of first cry and total crying time compared to positioning (swaddled and placed in a crib), holding by mother, placebo, pacifier use, no intervention or oral sucrose group, or both.Premature Infant Pain Profile (PIPP) scores were significantly lower in the breastfeeding group compared to positioning, placebo or oral sucrose group, or both. However, there was no statistically significant difference in PIPP scores when compared to no intervention. Douleur Aigue Nouveau-ne scores (DAN) were significantly lower in the breastfeeding group compared to the placebo group and the group held in mother's arms, but not when compared to the glucose group. Neonatal Infant Pain Scale (NIPS) was significantly lower in the breastfeeding group compared to the no intervention group, but there was no difference when compared to the oral sucrose group. The Neonatal Facial Coding System (NFCS) was significantly lower in the breastfeeding group when compared to oral glucose, pacifier use, holding by mother and no intervention, but no difference was found when compared to formula feeding.Supplemental breast milk yielded variable results. Neonates in the supplemental breast milk group had a significantly lower increase in heart rate, a reduction in duration of crying and a lower NFCS compared to the placebo group. Neonates in the supplemental breast milk group had a significantly higher increase in heart rate changes when compared to the sucrose group. Sucrose (in any concentration, i.e. 12.5%, 20%, 25%) was found to reduce the duration of cry when compared to breast milk, as did glycine, pacifier use, rocking, or no intervention. Breast milk was found not to be effective in reducing validated and non-validated pain scores such as NIPS, NFCS, and DAN; only being significantly better when compared to placebo (water) or massage. We did not identify any study that has evaluated safety/effectiveness of repeated administration of breastfeeding or supplemental breast milk for pain relief. If available, breastfeeding or breast milk should be used to alleviate procedural pain in neonates undergoing a single painful procedure rather than placebo, positioning or no intervention. Administration of glucose/sucrose had similar effectiveness as breastfeeding for reducing pain. The effectiveness of breast milk for painful procedure should be studied in the preterm population, as there are currently a limited number of studies in the literature that have assessed it's effectiveness in this population.

There is a lack of research on the effect of low dose of angiotensin receptor blockers combined with spironolactone, and the effect of high dose of angiotensin receptor blockers alone on the urinary albumin excretion rate (UAER) in elderly patients with early type 2 diabetic nephropathy (DN). We conducted a prospective, randomized, open-label, parallel-controlled study that included 244 elderly patients with early DN and mild-to-moderate essential hypertension. Patients were randomly divided into 4 groups: low-dose irbesartan (group A), high-dose irbesartan (group B), low-dose irbesartan combined with spironolactone (group C) and high-dose irbesartan combined with spironolactone (group D). Changes in UAER, serum potassium and blood pressure were compared. There were no statistical differences in the baseline characteristics among groups. Furthermore, no significant difference in blood pressure before and after treatment was found among different groups. After 72-week treatment, UAER in group D was lower compared to group A and B (P < 0.05). Meanwhile, compared with group B, UAER in group C decreased significantly (P < 0.05). Additionally, significantly higher serum potassium was found in group D compared to other groups (P < 0.05). Also, group D had the highest count of patients who withdrew from the study due to hyperkalemia compared to other groups (P < 0.05). Our results indicate high-dose irbesartan combined with spironolactone may be more efficient in reducing UAER in elderly patients with early DN, but this treatment could cause hyperkalemia. Low-dose irbesartan combined with spironolactone was shown to be safer and more effective in decreasing UAER compared to high-dose irbesartan.

Free-flap reconstruction via a retroauricular approach (RRA) after robot-assisted neck dissection (RAND) could have cosmetic benefits. This study aimed to compare the surgical outcomes of free-flap reconstruction via a RRA and via a transcervical approach in head and neck cancer. For this matched case-control study, 50 patients with head and neck cancer requiring free-flap reconstruction were divided into two groups: those reconstructed via a RRA group and those reconstructed via a transcervical approach (RTA group). The total operation time for free-flap reconstruction, the flap survival rate, the length of the hospital stay, the complications, and the scar satisfaction scores were compared between the two groups. The RRA group comprised 25 patients, and the RTA group had 25 patients. The mean operation time for reconstruction was 288 ± 77 min in the RRA group and 250 ± 98 min in the RTA group (p = 0.132). Flap failure occurred for two patients in the RRA group (8 %) and for one patient in the RTA group (4 %) (p = 1.000). The mean hospital stay was 21 ± 18 days in the RRA group and 23 ± 14 days in the RTA group (p = 0.669). The complications were comparable between the two groups. However, the overall scar satisfaction was significantly higher in the RRA group (p = 0.000). For patients with head and neck cancer, RRA has better cosmetic outcomes than RTA. The RRA approach could be used for select patients who undergo RAND and prefer to avoid a visible anterior neck scar.

Postoperative throat complaints such as postoperative sore throat (POST), dysphagia, and hoarseness frequently arises after tracheal intubation and throat packing for patient undergoing general anesthesia. This condition is very disturbing to patient. Avoiding POST is a major priority for these patients because preventing postoperative complications contributes to patient satisfaction. To describe and analyze the postoperative throat effects of nasopharyngeal packing and oropharyngeal packing in patients undergoing nasal surgery. A randomized comparative study. After obtaining approval of Ethical Committee 40 patients were included in study. After this patient were randomly allocated into two groups of 20 each. Group A - in which the oropharynx was packed and Group B - inwhich the nasopharynx was packed. General anesthesia were given and throat packing was done and patients were interviewed postoperatively for any throat complications such as sore throat, difficulty in swallowing (dysphagia), hoarseness of voice, throat irritation, and any other symptom pertaining to the study were noted and data were analyzed. T-test to compare the age, while Chi-square test and Fisher's exact test were used to compare sex distribution, sore throat, dysphagia, hoarseness, and throat irritation. Results showed statistically significant difference in incidence and severity of POST in Group A patients when compared to Group B patients to be more. Patients in Group A had a higher incidence of dysphagia when compared to their Group B counterparts. With respect to the incidence of hoarseness and throat irritation, there was no statistical significance between the groups. We concluded that the site of pharyngeal packing influences the incidence and severity of POST and as well as the incidence of dysphagia after general anesthesia. The use of nasopharyngeal packing in the patients undergoing nasal surgeries might lead to a reduction of the same.

Pilates exercise is often undertaken by people with multiple sclerosis (MS) who have balance and mobility difficulties. The primary aim of the study was to compare the effects of 12 weeks of Pilates exercises with relaxation on balance and mobility. Secondary aims were: (1) to compare standardized exercises with relaxation and (2) to compare Pilates exercises with standardized exercises. A multicenter, assessor-blinded, randomized controlled trial was conducted. Participants with Expanded Disability Status Scale scores of 4.0 to 6.5 were randomly allocated to groups receiving 12 weeks of Pilates exercises, standardized exercises, or relaxation. Assessments were undertaken at baseline and weeks 12 and 16 (primary outcome measure: 10-Meter Timed Walk Test [10MTW]). One hundred participants (mean age=54 years, 74% female) were randomized to study groups. Six participants relapsed (withdrew from the study), leaving 94 participants for intention-to-treat analysis. There was no significant difference in mean 10MTW measurements between the Pilates and relaxation groups. At 12 weeks, there was a mean reduction of 4.2 seconds for the standardized exercise group compared with the relaxation group (95% confidence interval [relaxation group minus standardized exercise group measurements]=0.0, 8.4) and a mean reduction of 3.7 seconds for the Pilates group compared with the standardized exercise group (95% confidence interval [Pilates group minus standardized exercise group measurements]=-0.4 to 7.8). At 16 weeks, mean 10MTW times for the standardized exercise group remained quicker than those for the Pilates and relaxation groups, although the differences were nonsignificant. There were no significant differences between the Pilates and relaxation groups for any secondary outcome measure. In this study, therapists were limited to a standardized basket of exercises that may have affected the study outcomes. Furthermore, choosing measures such as posturography to assess balance, accelerometry to assess walking, or a specific trunk assessment scale might have been more responsive in detecting changes in outcome. Participants did not improve significantly, either in the short term or at the 4-week follow-up, on the 10MTW after 12 weeks of Pilates exercises compared with 12 weeks of relaxation. © 2016 American Physical Therapy Association.

Introduction: Measurement of respiratory quotient (RQ) and resting energy expenditure (REE) has been shown to be helpful in designing nutritional regimens. There is a paucity of the literature describing the impact of a feeding regimen on the energy expenditure patterns. Therefore, we studied the effect of continuous vs. intermittent feeding regimen in head-injured patients on mechanical ventilation on RQ and REE. Methods: After institutional ethical approval, this randomized study was conducted in 40 adult male patients with head injury requiring controlled mode of ventilation. Patients were randomly allocated into two groups. Group C: Feeds (30 kcal/kg/day) were given for 18 h/day, with night rest for 6 h. Group I: Six bolus feeds (30 kcal/kg/day) were given three hourly for 18 h with night rest for 6 h. RQ and REE were recorded every 30 min for 24 h. Blood sugar was measured 4 hourly. Other adverse effects such as feed intolerance, aspiration were noted. Results: Demographic profile and SOFA score were comparable in the two groups. Base line RQ (0.8 vs. 0.86) and REE (1527 vs. 1599 kcal/day) were comparable in both the groups (P>0.05). RQ was comparable in both groups during the study period at any time of the day (P>0.05). Base line RQ was compared with all other RQ values measured every half hour and fluctuation from the base line value was insignificant in both groups (P>0.05). REE was comparable in both the groups throughout the study period (P>0.5). Adequacy of feeding as assessed by EI/MREE was 105.7% and 105.3% in group C and group I, respectively. There was no significant difference in the blood sugar levels between the two groups (P>0.05). Conclusion: We found from our study that RQ, REE, and blood sugar remain comparable with two regimens of enteral feeding – continuous vs. intermittent in neurosurgical patients on ventilator support in a ICU setup.

We examined the effectiveness of video-based decision training in national youth handball teams. Extending previous research, we tested in Study 1 whether a three-dimensional (3D) video training group would outperform a two-dimensional (2D) group. In Study 2, a 3D training group was compared to a control group and a group trained with a traditional tactic board. In both studies, training duration was 6 weeks. Performance was measured in a pre- to post-retention design. The tests consisted of a decision-making task measuring quality of decisions (first and best option) and decision time (time for first and best option). The results of Study 1 showed learning effects and revealed that the 3D video group made faster first-option choices than the 2D group, but differences in the quality of options were not pronounced. The results of Study 2 revealed learning effects for both training groups compared to the control group, and faster choices in the 3D group compared to both other groups. Together, the results show that 3D video training is the most useful tool for improving choices in handball, but only in reference to decision time and not decision quality. We discuss the usefulness of a 3D video tool for training of decision-making skills outside the laboratory or gym.

The arthrotomy techniques of knee surgery may cause varying degrees of disruption to the tissue blood supply. The aim of this study was to investigate the effects of the medial parapatellar (MPPa), midvastus (MVa), subvastus (SVa) and lateral parapatellar (LPPa) approaches on regional tissue perfusion of the knee. In this experimental study, a total of 28 female rabbits were applied with four different arthrotomy techniques as Group MPPa, Group MVa, Group SVa and Group LPPa. The blood supply of the tissue around the knee was examined by scintigraphic imaging including the perfusion reserve and T max , and biochemical alteration of the oxidative stress parameters including malondialdehyde (MDA), fluorescent oxidation products (FlOPs), and histopathological findings were evaluated on tissue samples after 3 weeks. The perfusion reserve was increased in all four groups compared to the healthy, contralateral knees. In the Group LPPa, the vascularity was significantly increased compared to the Group MPPa (p = 0.006). In the examination of biochemical parameters, the increase in MDA levels was statistically significant in the Group MPPa compared with the Group LPPa (p = 0.004), and in the Group MVa compared with the Group LPPa (p = 0.006). The increase in the value of MDA levels was striking in the Group MPPa and Group MVa compared with the control group (p = 0.004, p = 0.004, respectively). The increase in another oxidative stress parameter, the tissue FlOPs levels, was statistically significant in the Group MPPa compared with the control group (p = 0.035). The LPPa and SVa caused less oxidative stress and less disruption of the muscle blood supply, in biochemical and scintigraphic parameters, compared to the MPPa and MVa. Therefore, in clinical practice, the SVa is preferable to the MPPa and MVa in total knee arthroplasty and the LPPa should be preferred more frequently in selected cases with critical soft tissue viability.

Twenty pregnant Yankasa ewes were assigned to three groups to determine the effect of Trypanosoma evansi infection on pregnancy. Groups A and B comprising seven ewes each were infected with approximately 1.0 × 10(6) cells of T evansi per ewe through venepuncture at the second and third trimesters of pregnancy, respectively. Group C comprising six ewes served as uninfected control. There was slight pyrexia in the infected groups (groups A and B) but was absent in group C. The mean body weight, glucose concentration, and packed cell volume of ewes in group A were not significantly different from those in group C throughout the study. There was also no significant difference in mean glucose concentration between groups B and C. However, in group B, mean body weight was significantly (P < 0.05) lower compared to group C at week 2 and from week 4 post infection (pi) till the end of the study; the packed cell volume also significantly (P < 0.05) decreased but at weeks 4 and 6 pi. The mean plasma protein of ewes in group A was significantly (P < 0.05) increased compared to those of group C at weeks 7, 11 pi and thereafter till the end of the study. On the contrary, the plasma protein of ewes in group B decreased significantly (P < 0.05) compared to those in group C at weeks 2 and 6 pi. There were no reproductive losses throughout the study. This was characterized by insignificant differences in the gestation length between ewes in the infected groups (groups A and B) compared with those in group C. However, there were significant (P < 0.05) decreases in lamb birth weights of ewes in group B compared with ewes in groups A and C. Mice inoculation with blood from infected ewes postpartum was parasitemic 18 to 25 days pi, for ewes in group B, whereas none of the mice in groups A and C were parasitemic. Lambs born from the infected groups (groups A and B) were also aparasitemic for 40 days postpartum. It was therefore concluded that the T evansi isolate used caused mild trypanosomosis when infected at third trimester, whereas ewes infected at second trimester were resistant.

If variation in procedure times could be controlled or better predicted, the cost of surgeries could be reduced through improved scheduling of surgical resources. This study on the impact of similar consecutive cases on the turnover, surgical, and procedure times tests the perception that repeating the same manual tasks reduces the duration of these tasks. We hypothesize that when a fixed team works on similar consecutive cases the result will be shorter turnover and procedure duration as well as less variation as compared with the situation without a fixed team.

Two procedures, inguinal hernia repair and laparoscopic cholecystectomy, were selected and divided across a control group and a study group. Patients were randomly assigned to the study or control group. Preparation time, surgical time, procedure time, and turnover time. For inguinal hernia repair, we found a significantly lower preparation time and 10 minutes less procedure time in the study group, as compared with the control group. Variation in the study group was lower, as compared with the control group. For laparoscopic cholecystectomy, preparation time was significantly lower in the study group, as compared with the control group. For both procedures, there was a significant decrease in turnover time. Scheduling similar consecutive cases and performing with a fixed team results in lower turnover times and preparation times. The procedure time of the inguinal hernia repair decreased significantly and has practical scheduling implications. For more complex surgery, like laparoscopic cholecystectomy, there is no effect on procedure time.

To evaluate the safety profile of nicergoline compared with placebo and other active agents from published randomised controlled trials. Systematic review and meta-analysis of nicergoline compared with placebo and other active agents across various indications. MEDLINE, Medline-in-process, Cochrane, EMBASE, EMBASE alerts, Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Reviews (CDSR) and Cochrane Methodology Register (CMR) for all the randomised controlled trials, open-label or blinded, in adults treated with nicergoline. Studies published until August 2013 were included. 29 studies were included for data extraction. The studies included in this review were majorly from European countries and mostly in cerebrovascular disease (n=15) and dementia (n=8). The treatment withdrawals were comparatively lower in the nicergoline group as compared with the placebo group (RR=0.92; 95% CI 0.7 to 1.21) and other active comparators (RR=0.45; 95% CI 0.10 to 1.95), but the difference was non-significant. Incidence of any adverse events (AEs) was slightly higher (RR=1.05; 95% CI 0.93 to 1.2) while incidence of serious AEs was lower (RR=0.85; 95% CI 0.50 to 1.45) in the nicergoline compared with placebo group. Frequency of anxiety was significantly lower in nicergoline as compared with placebo (p=0.01). Other AEs including diarrhoea, gastric upset, dizziness and drowsiness were less frequent in the nicergoline group when compared with placebo/active drugs, but the difference was non-significant. Frequency of hypotension and hot flushes was slightly higher in the nicergoline group but the difference was non-significant. None of the studies reported any incidence of fibrosis or ergotism with nicergoline treatment. Nicergoline is an ergot derivative, but its safety profile is better than other ergot derivatives like ergotamine and ergotoxine. This systematic review and meta-analysis suggests that nicergoline has a good safety profile. None of the studies included in this systematic review reported any incidence of fibrosis or ergotism with nicergoline. Published by the BMJ Publishing Group Limited.

The aim of this study was to compare the results of two different modes of using multiple groups (instead of one large group) to identify problems and develop solutions. Many of the complex problems facing organizations today require the use of very large groups or collaborations of groups from multiple organizations. There are many logistical problems associated with the use of such large groups, including the ability to bring everyone together at the same time and location. A field study involved two different organizations and compared productivity and satisfaction of group. The approaches included (a) multiple small groups, each completing the entire process from start to end and combining the results at the end (parallel mode); and (b) multiple subgroups, each building on the work provided by previous subgroups (serial mode). Groups using the serial mode produced more elaborations compared with parallel groups, whereas parallel groups produced more unique ideas compared with serial groups. No significant differences were found related to satisfaction with process and outcomes between the two modes. Preferred mode depends on the type of task facing the group. Parallel groups are more suited for tasks for which a variety of new ideas are needed, whereas serial groups are best suited when elaboration and in-depth thinking on the solution are required. Results of this research can guide the development of facilitated sessions of large groups or "teams of teams."

This study aims to compare and evaluate the learning ability and performance differences between two groups of students undergoing project-based learning (PjBL), with one group having prior PjBL experience, while the other group is being freshly exposed to PjBL. More specifically, it examines if there are significant differences in knowledge score, problem-solving ability, and eventual project-deliverable outcomes between the two sets of students. Performances were compared via qualitative and quantitative analyses. Key findings have indicated a significant increase in fundamental formative knowledge; enhanced problem-solving abilities; and production of better performing artefacts with regard to the set of design skills between experienced and first-time PjBL groups. This study also highlighted that experienced PjBL students have less conflicts within their groups, and are more receptive to PjBL compared to first-time PjBL students. Results from this study provide a starting point for educators to seek new learning/facilitating strategies that are relevant based on the experience and learning styles of students.

Background and Aims: Earlier studies have shown that the type of laryngoscope blade influences the degree of hemodynamic response to endotracheal intubation. The aim of the study was to evaluate the hemodynamic response to oral endotracheal intubation with C-MAC laryngoscopy and McCoy laryngoscopy compared to that of Macintosh laryngoscopy in adult patients under general anesthesia. Material and Methods: This is a prospective randomized parallel group study. Ninety American Society of Anesthesiologists I patients were randomly allotted into three groups. Group A – Macintosh laryngoscopy (control group). Group B – laryngoscopy with McCoy laryngoscope. Group C – laryngoscopy with C-MAC video laryngoscope. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) were monitored at baseline (just before induction), just before intubation (T0), 1 min (T1), 3 min (T3), 5 min (T5), and 10 min (T10) after intubation. Intergroup comparison of study parameters was done by unpaired sample t-test for normal data and Mann-Whitney U-test for skewed data. For within-group comparison, the repeated measures of ANOVA for normal data and Friedman followed by Wilcoxon signed rank test for skewed data were performed. Results: In C-MAC group, the HR was significantly higher than the Macintosh group at 3 min after intubation, whereas SBP, DBP, and MAP were significantly higher at 1 min. McCoy group showed a similar response compared to Macintosh group at all time intervals. Conclusion: C-MAC video laryngoscope has a comparatively greater hemodynamic response than Macintosh laryngoscope. PMID:28096584

Emergency pediatric life support (EPLS) of children infected with transmissible respiratory diseases requires adequate respiratory protection for medical first responders. Conventional air-purifying respirators (APR) and modern loose-fitting powered air-purifying respirator-hoods (PAPR-hood) may have a different impact during pediatric resuscitation and therefore require evaluation. This study investigated the influence of APRs and PAPR-hoods during simulated pediatric cardiopulmonary resuscitation. Study design was a randomized, controlled, crossover study. Sixteen paramedics carried out a standardized EPLS scenario inside an ambulance, either unprotected (control) or wearing a conventional APR or a PAPR-hood. Treatment times and wearer comfort were determined and compared. All paramedics completed the treatment objectives of the study arms without adverse events. Study subjects reported that communication, dexterity and mobility were significantly better in the APR group, whereas the heat-build-up was significantly less in the PAPR-hood group. Treatment times compared to the control group did not significantly differ for the APR group but did with the PAPR-hood group (261±12 seconds for the controls, 275±9 seconds for the conventional APR and 286±13 seconds for the PAPR-hood group, P < .05. APRs showed a trend to better treatment times compared to PAPR-hoods during simulated pediatric cardiopulmonary resuscitation. Study participants rated mobility, ease of communication and dexterity with the tight-fitting APR system significantly better compared to the loose-fitting PAPR-hood.

Surgical wounds in diabetic patients still remain a problem till the present day. As a common plant found around the world, Hypericum perforatum L. (Hypericaceae) is traditionally prepared as an oily extract and used as a folk remedy for various diseases such as wounds, burns, cuts, etc. This study aims to evaluate the effect of St. John's wort (Hypericum perforatum) on problematic wounds while comparing oral and topical applications. Incisional and excisional wound models were made on the dorsal regions of 54 diabetic Spraque-Dawley rats. The rats were divided into the following six groups (n = 9): Group 1: control, Group 2: diabetic, Group 3: diabetic oral Hypericum perforatum, Group 4: diabetic topical Hypericum perforatum, Group 5: diabetic oral olive oil, and Group 6: diabetic topical olive oil. Groups 3 and 4 had significantly higher tensile strength, tissue hydroxyproline concentration, and collagen density compared with Group 2. Inflammatory cell density and collagen density on day 3 were significantly higher in Groups 3 and 6 compared with Group 2. On day 21, Groups 3 and 6 had significantly higher fibroblastic activity compared with Group 2. This study has proved that oral St. John's wort has more positive effects on problematic wounds compared with topical St. John's wort and olive oil, which is a vehicle. Hypericum perforatum results with faster inflammatory response and better healing. These results could be an addition to literature about the clinical usage of Hypericum perforatum on diabetic wounds.

Objectives The objective of this study was to compare the morbidity associated with long saphenous vein harvesting using the traditional open technique (A) against a minimally invasive technique using the Mayo vein stripper (B) that involves multiple short incisions. Design We conducted a prospective randomized controlled study in 80 patients undergoing first time coronary artery bypass grafting. Pain and healing was assessed on each postoperative day. Rings of long saphenous vein were subjected to organ-bath evaluation of endothelium-dependent and endothelium-independent relaxation. Results Three patients were excluded from the study, leaving 38 patients in Group A and 39 in Group B. With respect to operative procedure, Group A had a greater length of vein harvested than Group B. There was no statistical difference in pain scores and endothelium-dependent or endothelium-independent relaxation between the two groups. However there were significantly more infections in Group A compared with Group B. Conclusion Harvesting vein through multiple incisions using the Mayo vein stripper is quicker, results in fewer infections and has no deleterious effect on endothelial function compared to open technique.

The effectiveness of various therapeutic methods on bone fracture has been demonstrated in several studies. In the present study, we tried to evaluate the effect of local low-magnitude, high-frequency vibration (LMHFV) on rat tibia fracture in comparison with pulsed electromagnetic fields (PEMF) during the healing process. Mid-diaphysis tibiae fractures were induced in 30 Sprague-Dawley rats. The rats were assigned into groups such as control (CONT), LMHFV (15 min/day, 7 days/week), and PEMF (3.5 h/day, 7 days/week) for a three-week treatment. Nothing was applied to control group. Radiographs, serum osteocalcin levels, and stereological bone analyses of the three groups were compared. The X-rays of tibiae were taken 21 days after the end of the healing process. PEMF and LMHFV groups had more callus formation when compared to CONT group; however, the difference was not statistically significant (P = 0.375). Serum osteocalcin levels were elevated in the experimental groups compared to CONT (P ≤ 0.001). Stereological tests also showed higher osteogenic results in experimental groups, especially in LMHFV group. The results of the present study suggest that application of direct local LMHFV on fracture has promoted bone formation, showing great potential in improving fracture outcome.

The objective of this study was to compare the pain levels and analgesic consumption after single bundle ACL reconstruction with free quadriceps tendon autograft versus hamstring tendon autograft. A total of 48 patients scheduled for anatomic single-bundle ACL reconstruction were randomized into two groups: the free quadriceps tendon autograft group (24 patients) and the hamstring tendons autograft group (24 patients). A basic multimodal analgesic postoperative program was used for all patients and rescue analgesia was provided with tramadol, at pain scores over 30 on the Visual Analog Scale. The time to the first rescue analgesic, the number of doses of tramadol and pain scores were recorded. The results within the same group were compared with the Wilcoxon signed test. Supplementary analgesic drug administration proved significantly higher in the group of subjects with hamstring grafts, with a median (interquartile range) of 1 (1.3) dose, compared to the group of subjects treated with a quadriceps graft, median = 0.5 (0.1.25) (p = 0.009). A significantly higher number of subjects with a quadriceps graft did not require any supplementary analgesic drug (50%) as compared with subjects with hamstring graft (13%; Z-statistics = 3.01, p = 0.002). The percentage of subjects who required a supplementary analgesic drug was 38% higher in the HT group compared with the FQT group. The use of the free quadriceps tendon autograft for ACL reconstruction leads to less pain and analgesic consumption in the immediate postoperative period compared with the use of hamstrings autograft.

Assisted hatching in reproduction techniques has improved the successful implantation rates in certain groups of patients with poor prognosis. This study focuses on its effect in groups of patients with previous implantation failure and according to age groups. Compare the pregnancy rates of patients who turned to this technique following an implantation failure using in vitro fertilization with those of patients who did not use assisted hatching before another attempt of in vitro fertilization and according to specific age groups. Cases of patients using assisted hatching in our Center between January 2008 and December 2009 were studied. The results were compared in terms of age in three groups: group I, >35 years; group II, 35-39 years, and group III, > 40 years. Patients in group II had better pregnancy rate (30%) than those in groups I and III (16.98 and 20.83%, respectively). When comparing the results of the group of patients using assisted hatching with those of the group that did not, the first reported a 20% pregnancy rate versus no pregnancy in the other group.

The usefulness of branched-chain amino acid (BCAA) granules and BCAA-enriched nutrient mixtures for patients with liver cirrhosis is often reported. However, no randomized controlled studies have investigated the usefulness of these supplements in the nutritional intervention of cirrhotic patients receiving endoscopic treatment for esophageal varices. Patients without BCAA before endoscopic treatment were divided into study 1, and those who received BCAA were divided into study 2. In study 1, 44 eligible patients were divided into a control group (n = 13), a general liquid nutrient (snack) group (n = 15), and a BCAA-enriched nutrient mixture (BCAA-EN) group (n = 16). In study 2, 48 eligible patients were divided into a BCAA group (n = 24) and a BCAA-EN group (n = 24). The nutritional status including non-protein respiratory quotient (NPRQ) levels, weight gain, and albumin were evaluated on days 0, 7, and 50. In study 1, the BCAA-EN group showed significant improvement in NPRQ levels on day 7 as compared with the snack group. In study 2, the BCAA-EN group showed significant improvement in NPRQ levels on day 7 and in weight levels on day 50 relative to the BCAA group, while the BCAA group showed improved serum albumin levels on day 7 compared to the BCAA-EN group. The BCAA-enriched nutrient mixture maintained NPRQ and weight in cirrhotic patients. Our findings suggest that supplements including both BCAA and a nutritional energy supplement would be beneficial for cirrhotic patients undergoing endoscopic treatment for esophageal varices.

Background: The relationship between diabetes and periodontitis has been studied for more than 50 years and is generally agreed that the periodontal disease is more prevalent in diabetic patients compared to nondiabetics. Vascular changes like increased thickness of basement membrane in small vessels has been reported in diabetic patients, but the quantity of blood vessels in gingiva of diabetic patients has not been discussed much. The aim of this study was to compare the number of blood vessels in gingiva between chronic periodontitis (CP) patients, CP with diabetes (type 2), and normal healthy gingiva. Materials and Methods: The study included 75 patients, divided into three groups of 25 patients each-Group I with healthy periodontium (HP), Group II with CP, and Group III with CP with diabetes mellitus (CPDM). Gingival biopsies were obtained from the subjects undergoing crown lengthening procedure for Group I, and in patients with CP and in CPDM biopsies were collected from teeth undergoing extraction. Sections were prepared for immune histochemical staining with CD34. Results: Difference was observed in the average number of blood vessels when compared between HP, CP, and CPDM groups. Statistical significant difference was observed when the HP and CP groups and HP and CPDM groups were compared. Conclusion: The results of the study indicated that the number of blood vessels in gingival connective tissue is significantly higher in CP and CPDM patients. PMID:26015666

To evaluate possible contribution of maturational delay of brain stem in the etiology of breath-holding spells in children using brain stem auditory evoked potentials. The study group included children who experienced breath-holding spells. The control group consisted of healthy age- and sex-matched children. Age, gender, type and frequency of spell, hemoglobin, and ferritin levels in study group and brain stem auditory evoked potentials results in both groups were recorded. Study group was statistically compared with control group for brain stem auditory evoked potentials. The mean age of study and control groups was 26.3 ± 14.6 and 28.9 ± 13.9 months, respectively. The III-V and I-V interpeak latencies were significantly prolonged in the study group compared with the control group (2.07 ± 0.2 milliseconds; 1.92 ± 0.13 milliseconds and 4.00 ± 0.27 milliseconds; 3.83 ± 0.19 milliseconds; P = 0.009 and P = 0.03, respectively). At the same time, III-V and I-V interpeak latencies of patients without anemia in the study group compared with those of control group were significantly prolonged (2.09 ± 0.24 milliseconds; 1.92 ± 0.13 milliseconds and 4.04 ± 0.28 milliseconds; 3.83 ± 0.19 milliseconds; P = 0.007 and P = 0.01, respectively). Our results consider that maturational delay in myelination of brain stem may have a role in the etiology of breath-holding spells in children.

e-learning resources may be beneficial for complex or conceptually difficult topics. Leukaemia is one such topic, yet there are no reports on the efficacy of e-learning for leukaemia. This study compared the learning impact on senior medical students of a purpose-built e-learning module on leukaemia, compared with existing online resources. A randomised controlled trial was performed utilising volunteer senior medical students. Participants were randomly allocated to Study and Control groups. Following a pre-test on leukaemia administered to both groups, the Study group was provided with access to the new e-learning module, while the Control group was directed to existing online resources. A post-test and an evaluation questionnaire were administered to both groups at the end of the trial period. Study and Control groups were equivalent in gender distribution, mean academic ability, pre-test performance and time studying leukaemia during the trial. The Study group performed significantly better than the Control group in the post-test, in which the group to which the students had been allocated was the only significant predictor of performance. The Study group's evaluation of the module was overwhelmingly positive. A targeted e-learning module on leukaemia had a significant effect on learning in this cohort, compared with existing online resources. We believe that the interactivity, dialogic feedback and integration with the curriculum offered by the e-learning module contributed to its impact. This has implications for e-learning design in medicine and other disciplines.

Aims. To evaluate the efficacy and safety of mulberry twig alkaloid (SZ-A) tablet compared with acarbose in patients with type 2 diabetes. Methods. This clinical trial enrolled 38 patients who were randomized into two groups (SZ-A: 23; acarbose: 15) and were treated for 24 weeks. Patients and clinical trial staffs were masked to treatment assignment throughout the study. The primary outcome measures were glycated hemoglobin (HbA1c) and 1-hour and 2-hour postprandial and fasting plasma glucose levels from baseline to the end of treatment. Analysis included all patients who completed this study. Results. By the end of this study, HbA1c level in SZ-A group was decreased from baseline significantly (P < 0.001). No significant difference was found when compared with acarbose group (P = 0.652). Similarly, 1-hour and 2-hour postprandial plasma glucose levels in SZ-A group were decreased from baseline statistically (P < 0.05), without any significant differences compared with acarbose group (P = 0.748 and 0.558, resp.). The fasting plasma glucose levels were not significantly changed in both groups. One of 23 patients in SZ-A group (4.76%) and 5 of 15 patients in acarbose group (33.33%) suffered from gastrointestinal adverse events. Conclusions. Compared with acarbose, SZ-A tablet was effective and safe in glycemic control in patients with type 2 diabetes. PMID:27547230

Modern sulfonylureas like glimepiride offer effective glycemic control with extrapancreatic benefits and good tolerability. The objective of the present study was to evaluate and compare safety and efficacy of glimepiride and sitagliptin in combination with metformin in patients with type 2 diabetes mellitus (T2DM). In this open-label, randomized, comparative, multicenter study, a total of 305 T2DM patients who were either drug naïve or uncontrolled on metformin were randomized to glimepiride 1 or 2 mg/sustained-release metformin 1000 mg once daily (glimepiride group, n = 202) or sitagliptin 50 mg/metformin 500 mg twice daily (sitagliptin group, n = 103) for 12 weeks. Primary endpoint was change in glycosylated hemoglobin (HbA1c). Secondary endpoints were change in fasting plasma glucose (FPG), postprandial plasma glucose (PPG), body mass index (BMI) and to assess overall safety profile. At 12 weeks, there was a statistically significant difference in the mean HbA1c reduction in glimepiride group (0.42%) as compared to sitagliptin group (0.30%) ( P = 0.001). Mean reduction in FPG and PPG was also statistically significant in the glimepiride group as compared to the sitagliptin group ( P = 0.008). There was no significant difference in terms of change in BMI (0.07 ± 0.39 kg/m 2 vs. 0.08 ± 0.31 kg/m 2 ) in glimepiride and sitagliptin groups, respectively, ( P = 0.644) between both the groups. The incidences of hypoglycemic events were also comparable among both the groups. In T2DM patients, glimepiride/metformin combination exhibited significant reduction in glycemic parameters as compared to sitagliptin/metformin combination. Moreover, there was no significant difference between both the groups in terms of change in BMI and incidence of hypoglycemia.

The aim of this study, we have compared the advantages of oral dydrogestrone with vaginal progesterone (cyclogest) for luteal support in intrauterine insemination (IUI) cycles. Progesterone supplementation is the first line treatment when luteal phase deficiency (LPD) can reasonably be assumed. This study was conduct to compare the effect of oral dydrogestrone with vaginal Cyclogest on luteal phase support in the IUI cycles. This prospective, randomized, double blind study was performed in a local infertility center from May 2013 to May 2014. It consisted of 150 infertile women younger than35years old undergoing ovarian stimulation for IUI cycles. They underwent ovarian stimulation with oral dydrogesterone (20 mg) as group A and vaginal cyclogest (400 mg) as group B in preparation for the IUI cycles. Clinical pregnancy and abortion rates, mid luteal progesterone (7daysafter IUI) and patient satisfaction were compared between two groups. The mean serum progesterone levels was significantly higher in group A in comparison with group B (p=0.001). Pregnancy rates in group A was not statistically different in comparison with group B (p =0.58). Abortion rate in two groups was not statistically different (p =0.056) although rate of abortion was higher in group B in comparison with A group. Satisfaction rates were significantly higher in group A compared to group B (p<0.001). We concluded that oral dydrogestrone is effective as vaginal progesterone for luteal-phase support in woman undergoing IUI cycles. Moreover, the mean serum progesterone levels and satisfaction rates in dydrogestrone group were higher than cyclogest group.

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.

Anti-fibrinolytic agents are used to reduce obstetric blood loss as the fibrinolytic system is known to get activated after placental delivery. To evaluate the efficacy of parenteral tranexamic acid in reducing blood loss during normal labour and to compare it with the amount of blood loss in patients who received placebo in the third stage of labour. Patients with spontaneous labour or planned for induction of labour and fulfilling the inclusion criteria were recruited for the study. In each patient, the pre-delivery pulse rate, blood pressure, Hb gm% and PCV% were noted. Labour was monitored carefully using a partogram. The study group received Inj. Oxytocin and Inj. Tranexamic acid. The control group received Inj. Oxytocin and Placebo injection. Immediately after delivery of the baby, when all the liquor was drained, the patient was placed over a blood drape-a disposable conical, graduated plastic collection bag. The amount of blood collected in the blood drape was measured. Then the patient was given pre-weighed pads, which were weighed 2 h post-partum. The blood loss was measured by measuring the blood collected in the drape and by weighing the swabs before and after delivery. The total number of patients studied was 100-equally distributed in both the groups. The age group of the patients and BMI were comparable. There was a significant increase in the pulse rate and decrease in blood pressure in the control group as compared with the study group. The post-delivery haemoglobin and haematocrit were significantly reduced in the control group as compared to the study group. The mean blood loss at the end of 2 h was 105 ml in the study group and 252 ml in the control group. There was a significant increase in the usage of uterotonics and also in the need for blood transfusion in the control group; 12 % of the patients in the control group had to stay for more than 3 days compared to 2 % in the study group. Tranexamic acid injection, an antifibrinolytic agent when given prophylactically after the delivery of the baby, by intravenous route appears to reduce the blood loss and maternal morbidity during normal labour effectively.

Cross-linked hyaluronic acid (HA) gel is widely used in esthetic medicine. Late bacterial infection (LBI) is a rare, but severe complication after HA augmentation. The aim of this study was to determine whether patients who underwent the HA injection procedure and developed LBI had qualitatively different bacterial flora on the skin compared to patients who underwent the procedure without any complications. The study group comprised 10 previously healthy women with recently diagnosed, untreated LBI after HA augmentation. The control group comprised 17 healthy women who had a similar amount of HA injected with no complications. To assess the difference between the two groups, their skin flora was cultured from nasal swabs, both before and after antibiotic treatment in the study group. A significant increase in the incidence of Staphylococcus epidermidis was detected in the control group ( P =0.000) compared to the study group. The study group showed a significantly higher incidence of Staphylococcus aureus ( P =0.005), Klebsiella pneumoniae ( P =0.006), Klebsiella oxytoca ( P =0.048), and Staphylococcus haemolyticus ( P =0.048) compared to the control group. The bacterial flora on the skin differed in patients with LBI from the control group. The control group's bacterial skin flora was dominated by S. epidermidis . Patients with LBI had a bacterial skin flora dominated by potentially pathogenic bacteria.

Group-based interventions for weight loss are popular; however, little is known about how health service groups compare with the commercial sector, from either the participant or the group leader perspective. Currently, health professionals have little guidance on how to deliver effective group interventions. The present study aimed to compare and contrast leaders' and attendees' experiences of health service and commercial weight loss groups, through in-depth interviews and group observations. Purposive sampling, guided by a sampling frame, was employed to identify diverse groups operating in Scotland with differing content, structures and style. Data collection and analysis took place concurrently in accordance with a grounded theory approach. Thirteen semi-structured group observations and in-depth audio-recorded interviews with 11 leaders and 22 attendees were conducted. Identification of themes and the construction of matrices to identify data patterns were guided by the Framework Method for qualitative analysis. Compared to commercial groups, health service 'groups' or 'classes' tended to offer smaller periodic fixed term groups, involving gatekeeper referral systems. Commercial organisations provide a fixed branded package, for 'club' or 'class' members, and most commercial leaders share personal experiences of losing weight. Health service leaders had less opportunity for supervision, peer support or specific training in how to run their groups compared to commercial leaders. Commercial and health service groups differ in access; attendee and leader autonomy; engagement in group processes; and approaches to leadership and training, which could influence weight loss outcomes. Health service groups can provide different group content and experiences, particularly for those with chronic diseases and for populations less likely to attend commercial groups, such as men. © 2010 The Authors.

A cross-sectional comparative study was conducted to determine the nutritional status among physically active groups in Kota Bharu. The study population comprised 83 adult male athletes from 8 different types of sports (athlete group), 80 active men who exercised a minimum of 30 min per day for at least 3 times per week (exercise group), and 80 inactive men (sedentary group). All the respondents were aged between 18 to 44 years. Measurements taken from the respondents were anthropometric measurements, systolic (SBP) and diastolic (DBP) blood pressure, and serum total cholesterol (TC). The results showed that the combined prevalence of pre-obese (BMI 25.0-29.9) and obese (BMI ≥30.0) was 21.7% in athletes, 29.9% in exercise group, and 47.5% in sedentary group. The mean (± SD) percentage of body fat in athletes was 15.7 ± 5.4%, which was lower compared to the exercise (18.9 ± 5.5%) and sedentary (20.6 ± 5.8%) groups. The incidence of waist-to-hip ratio above 0.9 in athlete, exercise and sedentary groups was 9.6%, 18.7% and 31.3%, respectively. The incidence of hypertension (SBP ≥140 and/or DBP ≥90 mmHg) was 13.2% in athletes, 17.5% in exercise group and 42.5% in the sedentary group. The TC values showed that the prevalence of "high risk" individuals (TC ≥6.20 mmol/l) was also lower in athletes (20.5%), compared to the exercise (36.2%) and sedentary (47.5%) groups. The study revealed that individuals who are actively involved in physical activity, particularly in sport activities have better nutritional status compared to sedentary people. However, the nutritional status in the athlete and exercise groups was still unsatisfactory. The incidence of poor health status related to over nutrition in the active groups was rather high and needs attention from health professionals. Further studies are needed to determine nutritional practices among physically active groups.

In the latter half of the 20th century, registered nurse education moved to university degree level. As a result, there has been a reduction in access for students to clinical experience. In numerous studies, nursing graduates have reported that they do not feel prepared for practice. The importance of maximising every learning opportunity during nursing school is paramount. At Edith Cowan University, a program was initiated that allows students to become enrolled nurses at the midway point of their degree to enable them to work and therefore gain experience in the clinical practice setting during their education. This study investigated the effect of the program on the nursing students' perception of their clinical abilities and explored their ability to link theory to practice. The research design for this study was a quasi-experimental, prospective observational cohort study. The study included 39 second-year nursing students not enrolled in the program (Group 1), 45 second-year nursing students enrolled in the program (Group 2), and 28 third-year nursing students who completed the program and are working as enrolled nurses (Group 3). Participants were asked to complete a Five Dimension of Nursing Scale questionnaire. The quantitative analyses showed that students in Group 1 had statistically significant higher pre-questionnaire perceived abilities across all domains, except in two dimensions when compared to Group 2. The post-questionnaire analysis showed that Group 1 had statistically significant lower perceived abilities in four of the five dimensions compared to Group 2. Group 1 also had significantly lower abilities in all dimensions compared to Group 3. Group 3 had a significantly higher perception of their clinical abilities compared to Group 2. This study highlights the value of meaningful employment for undergraduate nursing students by providing opportunities to increase confidence in clinical abilities. Copyright © 2016 Elsevier Ltd.

implant placement Essure, sterilization procedure for women, were performed under hypnosedation (HYP) and compared to the operative anxiety and analgesia of 12 patients operated-on under general anesthesia (GA). prospective and comparative group study. two groups of twelve patients were matched and compared based on the choice of anesthetic technique: hypnotics (HYP) with possible additional sedation by propofol and remifentanil or GA involving propofol, sevoflurane and remifentanil. The assessment of anxiety and pain based on a visual analogy scale (0-10) and use of analgesics were studied in the recovery room and at discharge of hospital. The statistical analysis relies on nonparametric tests for paired data (Wilcoxon test). all patients were operated. The two groups are statistically comparable. The preoperative anxiety before premedication is lower in the HYP group (p<0.05). No conversion to general anaesthesia is necessary in the HYP group, but five patients were using sedatives drugs but doses are very low compared to general anaesthesia. The analgesic consumption was equivalent in both groups. we conclude that hypnosedation is a valuable alternative to traditional anesthetic techniques for ambulatory Essure implant. The use of hypnotic tool is an interesting alternative for the management of patients during invasive medical procedures or surgical, providing psychological benefits to the patient. 2010.

There are no large volume comparative studies available to compare the efficacy of lasers over lights for hair removal in Fitzpatrick V and VI skin types. This study is designed to compare the efficacy of Nd:YAG laser versus IPL in the darker skin types. Thirty-nine patients included in Group-1 were treated with Nd:YAG and 31 in Group-2 with IPL. Both groups received 5 sessions of treatment. The hair counts were assessed using digital photography and manual counting method before and after treatment and the results were analysed. Patient satisfaction scores and pain scores were recorded in each session and compared. Mean hair reduction in the IPL group was 25.70 and Nd:YAG group was 24.12 (95% CI). In the Nd:YAG group, 59% of subjects had burning sensation while the figure was 32.3% in IPL group. Burning was less in IPL group (p < 0.023). There were no statistically significant differences noticed regarding hyperpigmentation in both the groups (p < 0.115). Both Nd:YAG and IPL are equally effective for epilation of the darker skin types. Nd:YAG is associated with mild burning sensation in a significant number of patients. Patient satisfaction scores were comparable in both the groups.

Background and Aims: Infraclavicular (IC) approach of subclavian vein (SCV) catheterisation is widely used as compared to supraclavicular (SC) approach. The aim of the study was to compare the ease of catheterisation of SCV using SC versus IC approach and also record the incidence of complications related to either approach, if any. Methods: In the study, 60 patients enrolled were randomly divided into two groups of 30 patients each. In Gp. SC right SCV catheterisation was performed using SC approach and in Gp. IC catheterisation was performed using IC approach. Access time, success rate of cannulation, number of attempts to cannulate vein, ease of guidewire and catheter insertion and length of catheter inserted and any associated complications were recorded. Results: The mean access time in group SC for SCV catheterisation was 4.30 ± 1.02 min compared to 6.07 ± 2.14 min in group IC. The overall success rate in catheterisation of the right SCV using SC approach (29 out of 30) was better as compared with group IC (27 out of 30) using IC approach. First attempt success in the SC group was 75.6% as compared with 59.25% in the IC group. All successful subclavian vein  catheterisations in SC group and IC group were associated with smooth insertion of guidewire following subclavian venipuncture. Conclusion: The SC approach of SCV catheterisation is comparable to IC approach in terms of landmarks accessibility, success rate and rate of complications. PMID:24963180

OBJECTIVES: Previous studies reported comparable stent patency between covered self-expandable metallic stents (SEMS) and uncovered SEMS (UCS) for palliation of malignant gastric outlet obstruction (GOO). The aim of this study was to evaluate the efficacy and safety of the newly developed WAVE-covered SEMS (WCS), which has an anti-migration design, compared with UCS in gastric cancer patients with symptomatic GOO. METHODS: A total of 102 inoperable gastric cancer patients with symptomatic GOO were prospectively enrolled from five referral centers and randomized to undergo UCS or WCS placement. Stent patency and recurrence of obstructive symptoms were assessed at 8 weeks and 16 weeks after stent placement. RESULTS: At the 8-week follow-up, both stent patency rates (72.5% vs. 62.7%) and re-intervention rates (19.6% vs. 19.6%) were comparable between the WCS and the UCS groups. Both stent stenosis (2.4% vs. 8.1%) and migration rates (9.5% vs. 5.4%) were comparable between WCS and UCS groups. At the 16-week follow-up, however, the WCS group had a significantly higher stent patency rate than the UCS group (68.6% vs. 41.2%). Re-intervention rates in the WCS and UCS groups were 23.5% and 39.2%, respectively. Compared with the UCS group, the WCS group had a significantly lower stent restenosis rate (7.1% vs. 37.8%) and a comparable migration rate (9.5% vs. 5.4%). Overall stent patency was significantly longer in the WCS group than in the UCS group. No stent-associated significant adverse events occurred in either the WCS or UCS groups. In the multivariate analysis, WCS placement and chemotherapy were identified as independent predictors of 16-week stent patency. CONCLUSIONS: WCS group showed comparable migration rate and significantly more durable long-term stent patency compared with UCS group for the palliation of GOO in patients with inoperable gastric cancer.

This study aimed to compare stability, functional outcome, and second-look arthroscopic findings after anterior cruciate ligament reconstruction between remnant-preserving tibialis tendon allograft and remnant-sacrificing hamstring tendon autograft. We matched two groups (remnant-preserving tibialis tendon allograft group and hamstring tendon autograft group) in terms of demographic characteristics, associated injury, and knee characteristics. Each group consisted of 25 patients. Operation time was longer in the remnant-preserving tibialis tendon allograft group, but there was no significant intergroup difference in stability, clinical outcome, and second-look arthroscopic findings. When an autograft is not feasible in anterior cruciate ligament reconstruction, the remnant-preserving technique can produce comparable results in terms of restoration of function, stability of the knee, and degree of synovium coverage at second-look arthroscopy compared to remnant-sacrificing hamstring autograft.

[Purpose] The purpose of this study was to implement combined muscle strengthening and proprioceptive exercises to examine the effects of combined exercises on functional ankle instability. [Subjects and Methods] Experiments were conducted with 30 adult males and females. The study subjects were randomly assigned to either a control group (Group A), a muscle strengthening exercise group (Group B), or a combined muscle strengthening and proprioceptive exercise group (Group C) consisting of 10 subjects each. In Group A, measurements were only conducted before and after the experiment without any intervention, whereas the exercise programs for Group B and Group C were implemented three days per week for four weeks. [Results] Muscle strength showed significant increases in Groups B and C compared with the control group during plantar flexion, dorsiflexion, inversion, and eversion. The Cumberland ankle instability tool showed significant increases in Group B and Group C compared with Group A and significant increases in Group C compared with Group B. [Conclusion] Applying combined muscle strengthening and proprioceptive exercises to those who have functional ankle instability is more effective than applying only muscle strengthening exercises.

Current treatment strategies against the development of corrosive esophageal strictures remain unsatisfactory. Thus, the aim of the present study was to investigate the efficacy of keratinocyte growth factor, in the form of palifermin, for the prevention of stricture development following esophageal caustic injuries in a rat model. A total of 32 female Wistar albino rats were divided into four groups, which included the control (C), burn (B), steroid (S) and steroid plus palifermin (S/P) groups. An experimental corrosive esophageal burn model was established in the B, S and S/P groups. Weight gain was recorded and histopathological evaluation was performed for each group. Weight gain in the S and B groups was compared with the control group and statistically significant differences were observed. In addition, statistically significant differences in weight gain were observed between the S/P group and the B group. Histopathologically, statistically significant differences were identified with regard to submucosal collagen deposition, muscularis mucosa and tunica muscularis damage when comparing the B group with the C group. In addition, statistically significant differences were observed when comparing the S and S/P groups with the B group. Furthermore, significant submucosal collagen deposition and tunica muscularis damage were observed in the S group when compared with the S/P group. The stenosis indexes in the C and S groups were significantly lower compared with the B group. In addition, the stenosis index in the S/P group was significantly lower compared with the S group. To the best of our knowledge, the present study is the first to investigate the effect of palifermin on corrosive esophageal burns. The addition of palifermin to the corrosive esophageal burn standard treatment regimen was found to reduce the degree of fibrosis and ameliorate histopathological damage in an experimental model of corrosive esophagitis in rats.

The anatomy of the sinonasal area has a very wide rage of anatomical variations. The significance of these anatomical variations in pathogenesis of rhinosinusitis, which is the commonest disease in the region, is still unclear. The aims of the study were to compare the rate of sinonasal anatomical variations with development and severity of chronic rhinosinusitis patients. CT scan of paranasal sinuses images of 99 individuals were retrospectively reviewed. 65 cases of chronic rhinosinusitis (study group) who had undergone endoscopic sinus surgery were compared with 34 cases without chronic rhinosinusitis (control group). Also in study group Lund-Mackay score of the sinus disease were calculated and compared to the rate of related anatomical variations. There were 74 (74.7 %) males and 25 (25.2 %) females with ages ranging from 13 to 70 years (mean 32.2 years). The anatomical variations recorded were: Septal deviation 47 (72.3) in study and 25 (73.5 %) in control group, concha bullosa 27 (41.5 %) in study and 18 (52.9 %) in control group, overpneumatized ethmoid bulla 17 (26.1 %) in study and 14 (41.1 %) in control group, pneumatized uncinate 3 (4.6 %) in study and 3 (8.8 %) in control group, agger nasi 42 (64.6 %) in study and 19 (55.8 %) in control group, paradoxical middle turbinates 9 (13.8 %) in study and 4 (11.7 %) in control group, Onodi cell 6 (9.2 %) in study and 2 (5.8 %) in control group, Haller's cells (infraorbital ethmoid cell) 9 (13.8 %) in study and 7 (20.5 %) in control group. None of these results were statistically significant between study and control group (p > 0.05). Lund-Mackay score (which was assumed to show the severity of the disease) of the maxillary, ethmoid and frontal sinus were calculated and compared to rate of septal deviation, concha bullosa, agger nasi cells. No significant correlation was conducted (p > 0.05). The results of study showed no statistically significant correlation between sinonasal anatomical variations and pathologies of the paranasal sinus. Also these anatomical variations did not increase the severity of pre-existing sinusitis significantly. This is a retrospective cohort study (2b).

Etomidate is a popular anaesthetic induction agent, but it frequently causes myoclonic movements. Although both benzodiazepines and opioids reduce myoclonus, there has been no comparative study between these agents. Thus, we conducted a prospective, randomized study to compare midazolam and remifentanil as pre-treatment agents for reducing etomidate-induced myoclonus in 90 adults undergoing surgery. Patients were pre-treated before the etomidate injection, either with saline (Group C), midazolam 0.5 mg/kg (Group M) or remifentanil 1 microg/kg (Group R). Both Groups M and R showed a significantly lower incidence of myoclonus compared with Group C (17%, 17% and 77%, respectively). The incidence of myoclonus was not significantly different between Groups M and R, but 10% (n = 10) of the patients in Group R experienced remifentanil-related side-effects. We conclude that midazolam is probably a better choice than remifentanil for reducing etomidate-induced myoclonus during anaesthesia induction.

Abstract This study, a subgroup analysis of the data from the Organization Program of DiabEtes INsulIN ManaGement study, aimed to compare the efficacy and safety profiles of acarbose and metformin used in combination with premixed insulin. This analysis included 80 and 192 patients taking only 1 oral antidiabetic drug, classified into acarbose (treated with acarbose + insulin) and metformin groups (treated with metformin + insulin), respectively. The efficacy and safety data were analyzed for within- and between-group differences. The clinical trial registry number was NCT01338376. The percentage of patients who achieved target hemoglobin A1c (HbA1c) <7% in the acarbose and metformin groups were 38.75% and 30.73%, respectively, after a 16-week treatment. The average HbA1c levels in the acarbose and metformin groups were comparable at baseline and decreased significantly in both groups at the end of the study. All 7 blood glucose decreased significantly in both groups at endpoint compared with that at baseline. Insulin consumption was higher in the metformin group in terms of total daily amount and units/kg body weight. Incidences of hypoglycemia were similar in both groups. Body weight changed significantly in both groups from baseline to endpoint, but with no significant difference between the groups. Mean scores of Morisky Medication Adherence Scale improved in both groups at endpoint. Combination of insulin with acarbose or metformin could improve glycemic control in patients with type 2 diabetes mellitus. Acarbose and metformin were found to be comparable in terms of efficacy, weight gain, and incidence of hypoglycemia. PMID:28858080

Background: Endodontic infections require effective removal of microorganisms from the root canal system for long-term prognosis. Sodium hypochlorite (NaOCl) is the most effective irrigant currently, but potential complications due to its toxicity warrant search for newer alternatives. In this study, the antimicrobial efficacy of Morinda citrifolia (MC), green tea polyphenols and Triphala was compared with 5% NaOCl against Enterococcus faecalis. Materials and Methods: In this in vitro study sixty extracted human premolar teeth were infected with E. faecalis, a Group D Streptococci for 48 h. At the end of 48 h, the vital bacterial population was assessed by counting the number of colony-forming units (CFUs) on blood agar plate. Samples were divided into five groups; Group I (distilled water), Group II (NaOCl), Group III (MC), Group IV (Triphala), and Group V (green tea polyphenols). The samples were irrigated with individual test agents and CFUs were recorded. Kruskal–Wallis test was performed as the parametric test to compare different groups. Student's t-test was used to compare mean values between groups before and after treatment with test agents (P < 0.001). Results: NaOCl was the most effective irrigant the elimination of E. faecalis reinforcing its role as the best irrigant available currently and a gold standard for comparison of the experimental groups. Its antibacterial effect was comparable to Triphala. Among the experimental groups, MC showed the minimum antibacterial effect. Conclusion: The use of herbal alternatives as a root canal irrigant might prove to be advantageous considering the several undesirable characteristics of NaOCl. PMID:29576775

The aim of the present study was to compare three different forms of exercises namely lumbar stabilization, dynamic strengthening, and Pilates on chronic low back pain (LBP) in terms of pain, range of motion, core strength and function. In this study, 44 subjects suffering from non-specific LBP for more than 3 months were randomly allocated into the lumbar stabilization group, the dynamic strengthening group, and the Pilates group. Ten sessions of exercises for 3 weeks were prescribed along with interferential current and hot moist pack. Pain was assessed by visual analog scale, functional affection by modified Oswestry Disability Questionnaire, range of motion by assessing lumbar flexion and extension by modified Schober test and core strength was assessed by pressure biofeedback on day 1 and day 10 of the treatment. There was reduction of pain, improvement in range of motion, functional ability and core strength in all the 3 exercise groups. The improvement was significantly greater in the lumbar stabilization group for all the outcome measures, when compared the posttreatment after 10th session. Pairwise comparison showed that there was greater reduction of disability in the Pilates group than the dynamic strengthening group. It was concluded that the lumbar stabilization is more superior compared to the dynamic strengthening and Pilates in chronic nonspecific LBP. However, long-term benefits need to be assessed and compared with prospective follow-up studies.

Social cognition is commonly affected in psychiatric disorders and is a determinant of quality of life. However, there are few studies of treatment. To investigate the efficacy of intensive short-term dynamic psychotherapy on social cognition in major depression. This study used a parallel group randomized control design to compare pre-test and post-test social cognition scores between depressed participants receiving ISTDP and those allocated to a wait-list control group. Participants were adults (19-40 years of age) who were diagnosed with depression. We recruited 32 individuals, with 16 participants allocated to the ISTDP and control groups, respectively. Both groups were similar in terms of age, sex and educational level. Multivariate analysis of variance (MANOVA) demonstrated that the intervention was effective in terms of the total score of social cognition: the experimental group had a significant increase in the post-test compared to the control group. In addition, the experimental group showed a significant reduction in the negative subjective score compared to the control group as well as an improvement in response to positive neutral and negative states. Depressed patients receiving ISTDP show a significant improvement in social cognition post treatment compared to a wait-list control group.

Objective. To describe selected biochemical and hematological parameters (blood picture, liver enzymes, and kidney functions) in petrol station attendants in Mansoura city. Methods. This is a comparative cross-sectional study. The exposed group included 102 petrol station attendants. They were compared to a matched group of healthy 102 male service and office workers at the Faculty of Medicine, Mansoura University. The results of blood picture, liver enzymes, and kidney functions were compared between both groups. Results. Mean Red Blood Cells (RBCs) count, hemoglobin level, and Hematocrit (HCT) level were significantly lower in petrol station attendants than the comparison group. All other blood picture parameters showed nonsignificant difference between both groups. Liver enzymes, renal functions, serum albumin, and total protein showed statistically nonsignificant difference between both groups except for alanine aminotransferase (ALT) which was significantly higher in petrol station attendants. Conclusions. Some laboratory parameters among petrol station attendants showed changes that could be attributed to workplace exposure and should be given attention at preemployment and periodic medical examination.

This prospective comparative study was conducted in the department of Pediatric Surgery, Dhaka Shishu (children) Hospital during the period of June 2007 to September 2008 with the children of <12 years, diagnosed as acute Appendicitis. Patient selection was done by simple random technique by means of lottery. For open Appendectomy (OA) conventional method & for Laparoscopic Appendectomy (LA) 3 trocher technique was applied. Data was analyzed with the help of SPSS version 10. In this study 60 cases with acute Appendicitis including both gender were studied by two groups, group-A include 30 cases for laparoscopic and group-B include 30 cases for open appendectomy. Postoperative pain was assessed in both groups by using FLACC scale and compared at 1st 6-hours, 24 hours, 72 hours, 96 hours & at day 7. At 1st 6-hours, most of the children 24(80%) of group A had moderate pain whereas 17(56.7%) children of group B had severe pain (p<0.001). At 24 hours most of the patient 17(56.7%) of group A had mild pain compared to 27 (90%) patients of group B had moderate pain (p<0.0001). At 48 hours in group A most of the children 23(76.7%) had mild pain compared to moderate pain in 18(60%) children of group B (p<0.0001). Subsequently at 72 hours and at 96 hours most of the patients of LA group were free of pain compared to OA group. At final follow-up on day 7, 29(96.7%) children of group A had no pain compared to 26(86.7%) of group B. Regarding analgesics requirement both qualitative & quantitative requirements of analgesics were less in LA group than OA group. About post operative wound infection in group A only 1(3.3%) case had developed post operative wound infection whereas in group B 7(23.3 %) cases had. The mean (+/-SD) of post operative length of hospital stay was 52.00+/-11.62 (range 48-96) hours for group A and 76.00+/-12.74 (range 48-96) hours for group B children (p<0.001). Laparoscopic Appendectomy is more effective, preferable & superior procedure than that of open Appendectomy to reduce the post operative morbidity in children undergone appendectomy for acute appendicitis.

In this study, we aimed to compare the effects of various airway devices on QTc interval in rabbits under general anesthesia. The subjects were randomly separated into four groups: Group ETT, Group LMA, Group PLA, Group V-gel. Baseline values and hearth rate, mean arterial pressure and ECG was obtained at the 1st, 5th and 30th minutes after administration of anesthesia and placement of airway device and, QTc interval was evaluated. Difference was observed between ET group and V-gel group in the 5th minute mean arterial pressure values (p < 0.05). It was observed that QTc intervals at the 1st and 5th minute in the ET group significantly increased when compared with the other groups (p < 0.05). Again, it was observed that QTc interval of ET group at the 15th and 30th minute was longer when compared with PLA and V-gel groups (p < 0.05). It was also observed that QTc interval of LMA Group at the 5th minute after intubation significantly increased when compared with V-gel group (p < 0.05). It was observed that HR values of ETT group at the 1st, 5th and 15th minutes after intubation increased with regards to PLA and V-gel groups (p < 0.05). It was determined that the 30th minute hearth rate of ETT group was higher when compared to V-gel group (p < 0.05). In our study we observed that V-gel Rabbit affected both hemodynamic response and QT interval less than other airway devices.

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.

C-reactive protein (CRP) is an acute-phase reactant and has been proved to be a significant predictor of future cardiovascular events. Recent studies have demonstrated a correlation between periodontitis and elevated CRP levels. However, most of the studies have focused on chronic periodontitis and very few studies are done in patients with aggressive periodontitis. The aim of this study was to determine and compare the relative levels of serum CRP in aggressive and chronic periodontitis patients. A total of 75 systemically healthy subjects were divided into three groups: Group I, nonperiodontitis subjects; group II, chronic generalized periodontitis patients and group III, generalized aggressive periodontitis patients. All participants were subjected to quantitative CRP analysis using enzyme-linked immunosorbent assay. Mean CRP levels were significantly greater in both group II and III as compared to group I and group III having greater level than group II. Furthermore, CRP levels positively correlated with the amount of periodontal destruction as measured by probing depth and clinical attachment loss. The present study indicates a positive correlation between CRP and periodontal disease severity with particular concern in younger individuals that could be a possible underlying pathway in the association between periodontal disease and the observed higher risk for cardiovascular disease in periodontitis patients.

The benefits of occlusion treatment for amblyopia are well established.True compliance can be difficult to assess and is usually based on patient history. We hypothesize that more visits to the physician provides more chances to improve compliance. We conducted a prospective, comparative, blind trial in which 30 children with amblyopia were randomly assigned to be followed up more frequently (every 4 to 6 weeks) (study group) or as established on our standard regular basis (month intervals based on age in years) (control group). The primary outcome was to study differences in treatment compliance between these groups. The secondary outcome was to report compliance in a group of Chilean children and to compare survey results with adherence, to assess concordance between them. Baseline clinical characteristics were similar in the two groups. 30 patients were recruited. Mean compliance for all patients was 82%. Study group compliance was 83% versus 76% in control group (p = 0.5). Without epidemiology, intention to treat analysis (ITT), study group compliance was 97% compared to 76% in control group (p = 0.049). Pearson correlation between negative responses to a parental survey after treatment, of the percentage of adherence and compliance, was -0.57 and statistically significant (p = 0.013). There were no differences in patient compliance comparing more frequent evaluation versus a follow up evaluation based in an age according scheme. There is a high compliance to occlusion therapy in this group of Chilean children. If parents reported more negative adherence aspects in the survey, the worse the compliance.

Although there are several studies of Transcutaneous Electrical Nerve Stimulation (TENS) and exercise in myofascial pain syndrome, there are no studies comparing the effectiveness of Kinesio Taping (KT) and TENS in myofascial pain syndrome patients. To compare the early and late effects of TENS and KT on pain, disability and range of motion in myofascial pain syndrome patients. Sixty-nine patients were divided into three groups randomly as TENS+Exercise, KT+Exercise and exercise groups. Visual Analogue Scale (VAS), pain threshold, Neck Disability Index and cervical contralateral lateral flexion were employed in the evaluation of the patients performed before treatment, after treatment and 3rd month after treatment. The VAS, pain threshold, Neck Disability Index and contralateral lateral flexion values were improved in all groups both in after treatment and 3rd month after treatment (p< 0.01). In the comparison of after treatment vs. before treatment evaluations, VAS score was decreased in KT group compared to the TENS and control group (p= 0.001), in the TENS group compared to control group (p= 0.011). In the comparison of 3rd month and before treatment evaluations, VAS score was decreased in the TENS group compared to control group (p= 0.001) and in the KT group compared to the control group (p= 0.001). There was no significant difference between TENS and KT groups. All other parameters did not differ between the groups. TENS and KT added exercises can decrease pain severity and increase pain threshold, function and cervical range of motion in myofascial pain syndrome patients. Addition of TENS or KT to the exercise therapy resulted in more significant improvement compared to exercise therapy alone with a more pronounced improvement in KT group compared to the TENS group in the early period. Because KT was found to be more effective in decreasing the pain and had the advantage of being used in every 3 days, it seems to be beneficial in acute painful periods in myofascial pain syndrome patients.

Cell phones have become an integral part of everyday life. As cell phone usage has become more widespread, concerns have increased regarding the harmful effects of radiofrequency electromagnetic radiation from these devices. The current study was undertaken to investigate the effects of the emitted radiation by cell phones on testicular histomorphometry and biochemical analyses. Adult male Wistar rats weighing 180-200 g were randomly allotted to control, group A (switched off mode exposure), group B (1-hr exposure), group C (2-hr exposure) and group D (3-hr exposure). The animals were exposed to radiofrequency electromagnetic radiation of cell phone for a period of 28 days. Histomorphometry, biochemical and histological investigations were carried out. The histomorphometric parameters showed no significant change (p < .05) in the levels of germinal epithelial diameter in all the experimental groups compared with the control group. There was no significant change (p < .05) in cross-sectional diameter of all the experimental groups compared with the control group. Group D rats showed a significant decrease (p ˂ .05) in lumen diameter compared with group B rats. There was an uneven distribution of germinal epithelial cells in groups B, C and D. However, there was degeneration of the epithelia cells in group D when compared to the control and group B rats. Sera levels of malondialdehyde (MDA) and superoxide dismutase (SOD), which are markers of reactive oxygen species, significantly increased (MDA) and decreased (SOD), respectively, in all the experimental groups compared with the control group. Also sera levels of gonadotropic hormones (FSH, LH and testosterone) significantly decreased (p < .05) in groups C and D compared with the control group. The study demonstrates that chronic exposure to radiofrequency electromagnetic radiation of cell phone leads to defective testicular function that is associated with increased oxidative stress and decreased gonadotropic hormonal profile. © 2017 Blackwell Verlag GmbH.

Effect of vitamin E (Tri E®) on antioxidant enzymes and DNA damage in rats following eight weeks exercise

2011-01-01

Background Exercise is beneficial to health, but during exercise the body generates reactive oxygen species (ROS) which are known to result in oxidative stress. The present study analysed the effects of vitamin E (Tri E®) on antioxidant enzymes; superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (Cat) activity and DNA damage in rats undergoing eight weeks exercise. Methods Twenty four Sprague-Dawley rats (weighing 320-370 gm) were divided into four groups; a control group of sedentary rats which were given a normal diet, second group of sedentary rats with oral supplementation of 30 mg/kg/d of Tri E®, third group comprised of exercised rats on a normal diet, and the fourth group of exercised rats with oral supplementation of 30 mg/kg/d of Tri E®. The exercising rats were trained on a treadmill for 30 minutes per day for 8 weeks. Blood samples were taken before and after 8 weeks of the study to determine SOD, GPx, Cat activities and DNA damage. Results SOD activity decreased significantly in all the groups compared to baseline, however both exercised groups showed significant reduction in SOD activity as compared to the sedentary groups. Sedentary control groups showed significantly higher GPx and Cat activity compared to baseline and exercised groups. The supplemented groups, both exercised and non exercised groups, showed significant decrease in Cat activity as compared to their control groups with normal diet. DNA damage was significantly higher in exercising rats as compared to sedentary control. However in exercising groups, the DNA damage in supplemented group is significantly lower as compared to the non-supplemented group. Conclusions In conclusion, antioxidant enzymes activity were generally reduced in rats supplemented with Tri E® probably due to its synergistic anti-oxidative defence, as evidenced by the decrease in DNA damage in Tri E® supplemented exercise group.

The aim of the present study is to compare piezoelectric surgery to the conventional rotatory surgery in mandibular cyst enucleation, and to determine the 2 method's suitability and the postoperative outcomes. Eighty patients were included in the study. 35 male and 45 female, which showed cystic mandibular lesions, compared with the inferior alveolar nerve or the mental nerve. The patients were randomly divided into two groups. In the test group, cystectomy was performed using conventional rotatory instrumentation (rotatory-group), and in the other one piezoelectric surgery (piezo-group). The swelling was documented 24/48/72 h and 1 week post-surgery and the patients recorded their subjective postoperative pain daily for 7 days using a Visual Analog Scale (VAS). Patients treated with piezoelectric technique have presented a lower VAS, minor swelling and less recovery time compared to the rotatory-group. No lesions of the mandible nerve were detected with piezosurgery whereas surgery with rotary instruments resulted in 8% hypesthesia at least up to one week. The results of this study suggest that piezosurgery may be considered effective in cyst enucleation compared to traditional procedures with burs, since it grants the patients significantly less post-surgical pain and swelling.

Robotic colorectal surgery continues to rise in popularity, but there remains little evidence on the stress response following the procedure. The aim of this study was to evaluate the inflammatory response to robotic colorectal surgery and compare it with the response generated by open colorectal surgery. This was a prospective nonrandomized comparative study involving 61 patients with colorectal cancer. The evaluation of inflammatory response to either robotic or open colorectal surgery was expressed as changes in interleukin-1β, interleukin-1 receptor antagonist, interleukin-6, tumor necrosis factor-α, C-reactive protein, and procalcitonin during the first three postoperative days. Of the 61 patients, 33 underwent robotic colorectal surgery while 28 had open colorectal surgery. Groups were comparable with respect to age, sex, BMI, cancer stage, and type of resection. The relative increase of interleukin-1 receptor antagonist at 8 h postoperative, compared to baseline, was higher in the open group (P = 0.006). The decrease of interleukin-1 receptor antagonist on postoperative days 1 and 3, compared to the maximum at 8 h, was more pronounced in the open group than in the robotic group (P = 0.008, P = 0.006, respectively), and the relative increase of interleukin-6 at 8 h after incision was higher in the open group (P = 0.007). The relative increase of procalcitonin on postoperative days 1 and 3 was higher in the open group than the robotic group (P < 0.001, P = 0.004, respectively). This study shows that when compared with open colorectal surgery, robotic colorectal surgery results in a less pronounced inflammatory response and more pronounced anti-inflammatory action.

Severe burn injury has been shown to result in hypophosphatemia. Hypophosphatemia can cause cardiac, hematologic, immunologic, and neuromuscular dysfunction. This study compares serum phosphate levels and outcomes in patients who were administered a continuous, preemptive phosphate repletion protocol vs those who only received phosphate supplementation after they developed hypophosphatemia. Records of patients with greater than 19% TBSA burn admitted to the intensive care unit from 2006 to 2010 were reviewed. Patients were divided into two groups: historical controls who received responsive repletion when serum phosphate levels were less than 2.5 mg/dl (2006-2008) and the experimental group that received 30 mmol intravenous every 6 hours starting at approximately 24 hours after injury as long as serum phosphate levels were less than 4 mg/dl (2008-2010). Patients with chronic kidney disease or acute kidney injury were excluded. Data collected included age, weight, burn size, age, all serum phosphate levels, and total amount of phosphate administered. Differences in groups were compared with Mann-Whitney U test and Fisher's exact test. A total of 30 patients were included in the study, 20 in the responsive repletion group and 10 in the continuous repletion group. No significant difference was detected in age, sex, burn size, or full thickness burn size between groups. The continuous group had a statistically lower percentage of hypophosphatemic lab values compared with the responsive group, 13 ± 14% vs 45 ± 21% (P < .0001). No difference was found in percent of observations reflecting hyperphosphatemia (median of 2% in each group, P = .7). Four patients in the continuous group suffered cardiac and/or infectious complications compared with 16 in the responsive group (P = .04). Continuous, pre-emptive repletion of phosphate prevents hypophosphatemia after severe burn injury when compared with responsive repletion in historical controls. The protocol resulted in less hypophosphatemia without increasing the risk of hyperphosphatemia. This study also suggests that continuous repletion may result in fewer complications, but this needs to be confirmed in larger, prospective studies.

Acromioclavicular dislocation (ACD) is a common injury. According to the Rockwood classification, ACD is classified into six types (type I–VI); however, for type III injuries, it remains controversial whether or not operative treatment should be applied. Numerous studies have advocated early surgical treatment to ensure early rehabilitation activities. Thus, the present study aimed to investigate a modified closed-loop double-endobutton technique (MCDT), that may be used to repair Rockwood type III ACD. In the current study, 61 patients with Rockwood type III ACD were enrolled during a period of 5 years at the Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University. Patients were divided into three groups according to the surgical method used, the MCDT group (n=20), the common closed-loop double-endobutton technique (CCDT) group (n=21), and the clavicular hook plate fixation (CHPF) group (n=20). Preoperative and intraoperative information were recorded. Furthermore, the functional scores of injured shoulder were evaluated prior to surgery and following surgery with a 1-year follow-up. Among the three groups, postoperative functional scores were significantly more improved compared with those prior to surgery (P<0.05), and no significant difference was observed regarding the coracoclavicular interval with the 1-year follow-up (P>0.05). Postoperative functional scores in the MCDT and CCDT groups were significantly more improved compared those in the CHPF group (P<0.05). In addition, the duration of surgery in the MCDT group was significantly shorter compared with that in the CCDT group (P<0.05). Furthermore, compared with the CHPF group, the incision length was significantly shorter with reduced hemorrhage in the MCDT group (P<0.05). In conclusion, the results of the current study suggest that MCDT is more simple, convenient and efficient compared with CCDT, and is worth popularizing. PMID:29399102

Objective To evaluate the effect of high-intensity interval training (HIIT) on psychological symptoms, activity states, and cardiovascular functions in patients with myocardial infarction (MI) of low and moderate risk stratification. Methods This prospective study randomly allocated 44 patients with MI to 18 sessions of HIIT or conventional moderate-intensity continuous training (MICT). Outcome measures were assessed at baseline and after 18 sessions. Results Post-exercise cardiovascular and functional states, maximal oxygen uptake (VO2max), metabolic equivalents (METs), 6-Minute Walking Test (6MWT), and Korean Activity Scale/Index (KASI) scores were significantly improved in the HIIT group compared to those in the MICT group after 18 exercise sessions. In particular, VO2max was significantly (p<0.005) improved in the HIIT group (7.58 mL/kg/min) compared to that in the MICT group (2.42 mL/kg/min). In addition, post-exercise psychological states (i.e., scores of Fatigue Severity Scale [FSS] and depression items of the Hospital Anxiety and Depression Scale [HADS_D]) were significantly improved in the HIIT group compared to those in the MICT group after 18 exercise sessions. HADS-D was improved by 1.89 in the HIIT group compared to decrement of 0.47 in the MICT group. FSS was improved by 6.38 in the HIIT group compared to decrement of 0.77 in the MICT group (p<0.005). Conclusion This study demonstrates that HIIT can improve cardiac function, psychological, and activity states in low and moderate risk MI patients. Compared to conventional MICT, HIIT can improve cardiovascular functions, activity states, depression, and fatigue more effectively. PMID:29560335

To evaluate the effect of high-intensity interval training (HIIT) on psychological symptoms, activity states, and cardiovascular functions in patients with myocardial infarction (MI) of low and moderate risk stratification. This prospective study randomly allocated 44 patients with MI to 18 sessions of HIIT or conventional moderate-intensity continuous training (MICT). Outcome measures were assessed at baseline and after 18 sessions. Post-exercise cardiovascular and functional states, maximal oxygen uptake (VO 2max ), metabolic equivalents (METs), 6-Minute Walking Test (6MWT), and Korean Activity Scale/Index (KASI) scores were significantly improved in the HIIT group compared to those in the MICT group after 18 exercise sessions. In particular, VO 2max was significantly (p<0.005) improved in the HIIT group (7.58 mL/kg/min) compared to that in the MICT group (2.42 mL/kg/min). In addition, post-exercise psychological states (i.e., scores of Fatigue Severity Scale [FSS] and depression items of the Hospital Anxiety and Depression Scale [HADS_D]) were significantly improved in the HIIT group compared to those in the MICT group after 18 exercise sessions. HADS-D was improved by 1.89 in the HIIT group compared to decrement of 0.47 in the MICT group. FSS was improved by 6.38 in the HIIT group compared to decrement of 0.77 in the MICT group (p<0.005). This study demonstrates that HIIT can improve cardiac function, psychological, and activity states in low and moderate risk MI patients. Compared to conventional MICT, HIIT can improve cardiovascular functions, activity states, depression, and fatigue more effectively.

To compare efficacy of 'split hours part-time patching' and 'continuous hours part-time patching' for the treatment of anisometropic amblyopia. We designed a prospective, interventional, non-randomised, comparative pilot study involving children between 4 and 11 years of age with anisometropic amblyopia who were treated with either continuous wear (Group A) or split hours part-time patching (Group B) as per parents wish, after appropriate discussion with the parents. Children were followed-up for the improvement in visual acuity and the compliance at each follow-up visit. 44 and 24 children were recruited in Group A and Group B, respectively (mean ± SD baseline BCVA of the amblyopic eye: 0.99 ± 0.32 and 0.95 ± 0.23 logMAR, respectively). BCVA (adjusted for baseline BCVA and age) at 3 months in Group A (0.59 ± 0.24) was comparable (p=0.08) with that in Group B (0.71 ± 0.24). This was same even at 6 months (0.51 ± 0.25 in Group A and 0.59 ± 0.25 in Group B, p=0.25). The improvement in BCVA at 3 months was also comparable (p=0.06) in Group A (0.39 ± 0.23) and Group B (0.26 ± 0.23). The improvement in BCVA at 6 months was also comparable (p=0.14) in Group A (0.47 ± 0.26) and Group B (0.37 ± 0.26). Both patching regimens lead to significant and comparable improvement in BCVA in anisometropic amblyopia up to 6 months of follow-up.

The aim of this study was to compared the efficacy of paracetamol-codeine phosphate and naproxen sodium-codeine phosphate on postoperative pain and tramadol consumption during the first 24 hours after a lumbar disk surgery. After Ethics Committee approval and informed consent had been obtained, 64 patients were allocated into three groups. Patients received oral paracetamol-codeine (300 mg + 30 mg; Group P), naproxen sodium-codeine (550 mg + 30 mg; Group N), or placebo tablets (Group C) 30 minutes prior to induction of anesthesia. Patient-controlled analgesia was supplied postoperatively using tramadol. Pain intensity, tramadol consumption, and side effects were recorded every 1 hour, 2 hours, 6 hours, 12 hours, and 24 hours after surgery. Whole study period pain intensity (visual analogue scale scores) was lower in Group P (p = 0.007) and Group N (p = 0.001), compared with Group C, however, there was no statistically significant difference between Group P and Group N regarding pain intensity (p > 0.05). Tramadol consumption was lower in Group P and Group N, compared with Group C (p < 0.001), and in turn the lowest incidence of tramadol consumption was detected in Group P compared with Group N (p < 0.001) and Group C (p < 0.001). Side effects were similar between the groups. Preemptive administration of paracetamol-codeine and naproxen sodium-codeine combination significantly reduced tramadol consumption and provided more effective analgesia compared with placebo. The paracetamol-codeine combination was superior to naproxen sodium-codeine with regard to tramadol consumption. Copyright © 2015. Published by Elsevier Taiwan.

There are no studies that looked into the bubble eliminating efficacy of polyethylene glycol with ascorbic acid (PEGA), which has been one of the shortcomings of polyethylene glycol (PEG). In this study, we compared newly introduced PEGA regimen by adding either simethicone or 1 L of water. A prospective randomized controlled study was carried out at Dongguk Universtiy Gyeongju Hospital from July 2014 to September 2014. A total of 90 patients were randomly assigned to 3 groups; PEGA group (n=30) which served as control, simethicone addition group (n=30) to which simethicone 400 mg was additionally prescribed, and water addition group (n=30) to whom additional 1 L of water was given. Cleansing effectiveness, gas elimination efficacy, side effects, and patient satisfaction were compared between the groups. PEGA group demonstrated the highest cleansing effectiveness, but there was no statistically significant difference among the groups. Simethicone addition group showed significantly lesser amount of bubbles than the other groups (2.57±2.05 vs. 1.10±1.83 vs. 2.60±2.84, p=0.017). The rates of side effects in each group were 20.00% vs. 16.77% vs. 53.33%. Water addition group had significantly more side effects than the PEGA group and the simethicone addition group (p=0.003). The patient satisfaction score of each group was 3.37±0.85 vs. 3.73±0.74 vs. 3.20±0.66 with simethicone addition group showing significantly higher satisfaction than water addition group (p=0.020). PEGA bowel preparation agent showed satisfactory bowel cleansing despite the decrease in dosage, and addition of simethicone resulted in better bubble elimination.

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 compare the usefulness of preoperative treatment with triptorelin, letrozole or ulipristal acetate or no treatment before hysteroscopic removal of uterine submucosal myomas. Single center prospective non-randomized comparative pilot study. The study included consecutive premenopausal patients undergoing hysteroscopic resection of myomas graded as type 0, type 1 or type 2 according to the FIGO classification with diameter between 20 and 35 mm. Exclusion criteria were: associated polyps, associated non-hysteroscopic surgical procedures, >2 myomas requiring hysteroscopic resection. This study enrolled patients who underwent either direct surgery (group S; n=23) or 3-month preoperative treatment with triptorelin (3.75 mg every 28 days; group T; n=20), letrozole (2.5 mg/day; group L; n=11) or ulipristal acetate (5 mg/day; group U; n=7). Patients underwent hysteroscopic resection of the myomas. All medical treatments caused a significant decrease in the volume of myomas (group T, p<.001; group L, p<.001; group U, p=.006); however, the percentage decrease in myoma volume was lower in group U than in group T (p=.001) and in group L (p=.010). The hysteroscopy time was higher in group S than in group T (p<.001) and in group L (p=.001); there was no significant difference in the hysteroscopy time between group S and group U (p=.206). Fluid absorption was lower in group T than in group S (p=.002) and in group L than in group S (p=.048); fluid absorption was similar in group S and group U (p=.110). Intra- and postoperative complications, postoperative pain, and patient satisfaction were similar in the four study groups. Surgeon's evaluation of operative difficulty was better in group T than in group S (p<.005). Preoperative treatment with triptorelin and letrozole decreases the hysteroscopy time and the volume of fluid absorbed during hysteroscopic resection of uterine submucosal myomas.

This study compared the effectiveness of two group treatments, behavioral activation (BA) and cognitive therapy (CT), in reducing subsyndromal anxiety and depressive symptoms in a sample of Iranian university students. Twenty-seven Iranian university students who scored 18 or higher on the depression subscale and 16 or higher on the anxiety subscale of the Depression, Anxiety, and Stress Scale (DASS-42) were randomly assigned into treatment groups. One group received 8 sessions of BA (n = 14), and the other received 8 sessions of group CT (n = 13). Analysis of covariance revealed that the BA group had a significantly greater reduction in depressive symptoms than the CT group. However, there were no significant differences between the two groups in the levels of anxiety, stress symptoms or functional impairment after treatment. This study found evidence for the effectiveness of BA in reducing anxiety, depressive and stress symptoms and functional impairment compared to CT. BA was more effective than CT in improving depressive symptoms and was as effective as CT in decreasing anxiety, stress and functional impairment. BA is also a cost-effective intervention, particularly in group formats.

This study compared trunk exercises based on the Bobath concept with routine neurorehabilitation approaches in multiple sclerosis (MS). Bobath and routine neurorehabilitation exercises groups were evaluated. MS cases were divided into two groups. Both groups joined a 3 d/wk rehabilitation program for 8 wk. The experimental group performed trunk exercises based on the Bobath concept, and the control group performed routine neurorehabilitation exercises. Additionally, both groups performed balance and coordination exercises. All patients were evaluated with the Trunk Impairment Scale (TIS), Berg Balance Scale (BBS), International Cooperative Ataxia Rating Scale (ICARS), and Multiple Sclerosis Functional Composite (MSFC) before and after the physiotherapy program. In group analysis, TIS, BBS, ICARS, and MSFC scores and strength of abdominal muscles were significantly different after treatment in both groups (p < 0.05). When the groups were compared, no significant differences were found in any parameters (p > 0.05). Although trunk exercises based on the Bobath concept are rarely applied in MS rehabilitation, the results of this study show that they are as effective as routine neurorehabilitation exercises. Therefore, trunk exercises based on the Bobath concept can be beneficial in MS rehabilitation programs.

To compare two teaching methodologies for PROCES (a basic cardiopulmonary resuscitation (b-CPR) programme for secondary school students): one exclusively performed by school teachers (study group) and another by a mixed team of school teachers and healthcare providers (control group). According to their preferences, teachers chose either method and students were consequently assigned to the control or study group. All participants took a 10 multiple-choice question exam regarding b-CPR skills twice: immediately after PROCES and one year later. Eight or more correct answers was considered satisfactory learning. Results between groups were compared. Associations between satisfactory learning and some student characteristics were analysed. Immediately after PROCES, 442 students (219 in the study group and 223 in the control group) took the exam. The percentage of satisfactory learning was not different: 67.1% in the study group and 64.6% in the control group. Immediate satisfactory learning was related to the absence of pending subjects in the control (odds ratio (OR) 2.31, 95% CI 1.16 to 4.64) and study (OR 5.87, 95% CI 1.22 to 28.20) groups. One year later, a greater percentage of retention of b-CRP skills was detected in the study group (57.1% vs 40.6%; p = 0.01). The absence of any pending subject (OR 6.86, 95% CI 1.83 to 25.66) was independently associated with better retention in the study group, but not the control group. Secondary school teachers, previously trained in b-CPR, can teach these skills effectively to 14-16-year-old students using PROCES. The retention of b-CPR skills is greater with this methodology compared with a more standardised programme.

To assess the efficiency and treatment outcome of patients treated with corticotomy-assisted en-masse orthodontic retraction as compared with the en-masse retraction without corticotomy. Forty adult patients with bimaxillary protrusion requiring correction of bidental proclination constituted the sample. The study group consisted of 22 patients (male 11, female 11) willing to undergo surgery to reduce the duration of their orthodontic treatment and 18 patients (male 9, female 9) desirous of undergoing conventional orthodontic treatment without surgical intervention constituted the control group. Comparison of rate of retraction and anchor loss between the study and the control group was assessed. Average rate of space closure of 1.8 mm/month in the maxilla and 1.57 mm/month in the mandible was observed in the study group compared to 1.02 mm/month in the maxilla and 0.87 mm/month in the mandible in the control group. The rate of retraction accelerated during the first 2 months of retraction. Molar anchor loss of approximately 0.6 mm occurred in the study group, and 1.8 mm occurred in the control group during the 4 months. The rate of retraction with study group was twice as faster when compared to the control group, accelerating during the first 2 months of retraction. There was better anchorage control with the undecorticated molar segment during the retraction period but was found to increase as time advanced.

Aim The aim of the present study was to assess the protective effects of magnesium sulfate (MgSO4) on ischemia/reperfusion (I/R) induced ovarian damage in a rat ovarian torsion model. Methods Forty-two female Sprague Dawley rats were included in the study. They were divided into six groups as Group 1, sham; Group 2, bilateral ovarian torsion; Group 3, bilateral ovarian torsion–detorsion; Group 4, MgSO4–sham; Group 5, MgSO4–bilateral ovarian torsion; Group 6, bilateral ovarian torsion–MgSO4–detorsion. Both torsion and detorsion periods lasted 3 hours. In Groups 4, 5 and 6, MgSO4 (600 mg/kg) was administered by intraperitoneal route 30 minutes before sham operation, torsion and detorsion, respectively. At the end of the study period, both ovaries were removed. One of the ovaries was used for histopathological analyses and the other for biochemical analyses. Results In the torsion–detorsion group, all the histopathological scores were higher compared to the sham and torsion only group (p<0.05). Administration of MgSO4 only caused significant decrease in the inflammatory cell scores of the torsion–detorsion group (p<0.05). MgSO4, whether given before torsion or before detorsion, suppressed malondialdehyde levels when compared to the untreated groups (p<0.01 and p<0.001, respectively). Glutathione peroxidase activities were significantly higher in the MgSO4 applied torsion and detorsion groups than Groups 2 and 3 (p<0.05, for both). Administration of MgSO4 also caused an increase in glutathione levels in the torsion and detorsion groups compared to the torsion only and detorsion only groups (p<0.05, for both). Also, total oxidant status levels decreased in the MgSO4 applied torsion and detorsion groups compared to the untreated corresponding ones (p<0.01 and p<0.001, respectively). MgSO4 significantly decreased the Oxidative Stress Index levels in the torsion–detorsion group compared to Group 2 (p<0.001). Conclusion Histopathological and biochemical analysis revealed that prophylactic treatment with MgSO4 reduces the changes observed in I/R injury in a rat model. PMID:29535502

Changing smokers' risk perceptions--for better or worse?

2014-03-01

This study investigated the effect of a smoking health message on smokers' comparative optimism. Two groups watched an anti-smoking scenario, with one group imagining being part of the scenario. Participants, including controls, completed comparative optimism ratings for four smoking-related illnesses. The intervention had negative consequences with both intervention groups reporting significantly higher comparative optimism versus the control group for all four smoking-related illnesses. It is concluded that media health messages can be powerful tools in changing comparative optimism but are influenced by peoples' prior perceptions. Health messages need to be systematically assessed to understand prior beliefs of the target audience.

Since Dupuytren's contracture is a common disorder, the costs for its surgical treatment impose a considerable burden on the healthcare system. For the first time in the German-speaking area, this study aimed to provide a comparative cost-effectiveness analysis for partial fasciectomy vs. treatment with Clostridium histolyticum collagenase (CCH). A retrospective monocentric study of the period from 2012 to 2014 comprised 40 patients with previously untreated Dupuytren's contracture of one finger. 20 outpatients received one CCH treatment (Group 1), while 20 inpatients underwent partial fasciectomy (Group 2). The direct pre-interventional treatment and post-interventional costs were compared. The direct post-interventional and postoperative results were comparable. Group 1 (CCH) showed a mean reduction in contracture of 96.4%; in Group 2 (partial fasciectomy), this was 97.7%. There were fewer complications in Group 1 than in Group 2. Mean treatment costs in Group 1 were € 1 458.60 and in Group 2, € 5 315.20. Treatment with CCH is more cost effective than with partial fasciectomy. This is due to greater costs for personnel, time and surgical material, as well as the treatment of the more frequent complications in Group 2. Despite the limited comparability, our findings are consistent with the present international literature. © Georg Thieme Verlag KG Stuttgart · New York.

The aim of this study was to prospectively compare the radiographic and clinical outcomes between the posterior fossa decompression (PFD) and PFD with duraplasty (PFDD) procedures in adolescent patients with Chiari malformation type I (CMI). Ninety adolescent patients with CMI were randomly assigned to undergo either PFDD or PFD. In both groups, a dissection from the occipital bone was performed. The dura was not opened in the PFD group, and the outer layer of dura was resected. However, in the PFDD group, the dura mater was opened and expanded. Data were analyzed for clinical outcome, complications, and syrinx resolution. The age, gender, and preoperative neurologic status were similar between the 2 groups. Compared with the PFD group, patients undergoing PFDD had significantly longer operation time, longer postoperative drainage time, and higher drainage volume. At the latest follow-up, no statistically significant difference was found between the 2 groups in terms of syrinx resolution. The clinical outcomes were similar in the PFDD and PFD group. Compared with the PFD group, patients in the PFDD group had a higher incidence of cerebrospinal fluid leak. Compared with the more aggressive decompression with duraplasty, PFD without duraplasty produces comparable radiologic and clinical outcomes and is associated with a lower risk of complications.

The aim of study was to assess if preoperative stoma selection and adequate patient's teaching can affect the postoperative patient's quality of life. The study was performed in two university hospitals of Lithuania: Kaunas University of Medicine Hospital and Kaunas Oncology Hospital. Patients were divided into three groups. Patients were asked to answer the questionnaire the day before the stoma creation operation and two months after the operation. Questionnaires EORTC QLQ-C30, EORTC QLQ-CR38 and 10 supplementary questions were used. The results of the study show that following the stoma operation, when compared with preoperative results, general quality of life did not change significantly in groups I and II. Patients who received adequate education and preoperative stoma siting had better emotional functioning and less gastrointestinal problems. The financial problems of the patients in group I were significantly less than in the control group. Patients who received the adequate teaching without preoperative stoma selection experience better sexual satisfaction compared with control group. Stoma related problems were less in group I and II when comparing with the control group. The quality of the patients' teaching, adequacy and comfort of stoma site and satisfaction with the medical staff were significantly better in the group I and group II when compared to control group. Moreover, these results were significantly higher in the group I than in group II. CONCLUSIONS. The teaching the patients preoperatively and postoperative proceeding helps them to gain better experience in self stoma care hence reducing the psychological, physical, emotional, social and sexual problems.

To investigate the efficacy and safety of the combined therapy with high-frequency transcutaneous electrical nerve stimulation (hf-TENS) and thermotherapy in relieving primary dysmenorrheal pain. In this randomized, single-blind, placebo-controlled study, 115 women with moderate or severe primary dysmenorrhea were assigned to the study or control group at a ratio of 1:1. Subjects in the study group used an integrated hf-TENS/thermotherapy device, whereas control subjects used a sham device. A visual analog scale was used to measure pain intensity. Variables related to pain relief, including reduction rate of dysmenorrheal score, were compared between the groups. The dysmenorrheal score was significantly reduced in the study group compared to the control group following the use of the devices. The duration of pain relief was significantly increased in the study group compared to the control group. There were no differences between the groups in the brief pain inventory scores, numbers of ibuprofen tablets taken orally, and World Health Organization quality of life-BREF scores. No adverse events were observed related to the use of the study device. The combination of hf-TENS and thermotherapy was effective in relieving acute pain in women with moderate or severe primary dysmenorrhea. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

[Purpose] The purpose of this study was to determine the effect of proprioceptive training on foot progression angle, weight-bearing ratio, and knee adduction moment in patients with degenerative osteoarthritis of the knee. [Subjects] The subjects were 37 patients diagnosed with Kellgren-Lawrence grade 2 or 3 degenerative knee osteoarthritis. They were randomly allocated to three groups: a proprioceptive training group (PT group), quadriceps strengthening group (QS group), and control group. [Methods] The study parameters of the three groups were compared before and after a 12-week training period. Therapeutic exercises were performed twice per week for 12 weeks. Outcomes included the foot progression angle, weight-bearing ratio, and knee adduction moment. [Results] First, a significant difference in the foot progression angle was observed among the groups, significantly increasing in the PTG compared with the CG. Second, a significant difference in the weight-bearing ratio was observed among the groups, significantly increasing in the PTG compared with the CG. Third, a significant difference in the first peak knee adduction moment was observed among the groups, significantly decreasing in the PTG compared with the CG. [Conclusion] The results of the present study indicate that proprioceptive training increased the foot progression angle and weight-bearing ratio and decreased the first peak knee adduction moment. Moreover, incorporating proprioceptive training into a physical therapy exercise program could improve functional ability and delay the progression of degenerative osteoarthritis. PMID:25729170

Certain factors in mothers could be risk indicators for certain diseases in their children. Hence, this study was undertaken to assess maternal risk indicators for the development of early childhood caries in their children. A comparative, cross-sectional study was designed among 180 mother-child pairs attending various Anganwadi centers. Demographic, dietary, oral hygiene practices and other necessary information were collected from mothers using a structured questionnaire. Caries status and amount of plaque were recorded through clinical examination. Nonstimulated saliva from mothers was cultured for mutans streptococci (MS). Data were analyzed using SPSS version 17. Chi-square, Student's t-test, and logistic regression were used. A P ≤ 0.05 was considered statistically significant. In the study group, 73.3% of mothers had caries as compared to only 53.3% mothers in control group. While mean DMFT and mean DMFS of mothers in the study group was 3.78 ± 3.91 and 8.37 ± 12.2, respectively, the same for the mothers in the control group was 2.66 ± 3.01 and 5.8 ± 5.3. Sixty (66.7%) out of ninety mothers in the study group had a high MS count as compared to only 40 (44.4%) mothers in control group (P = 0.003). The present study showed that high salivary MS count and decay in mothers could be important risk indicators for the development of caries in their children.

The aim of the study was to test if the addition of CGF to the Masquelet technique contributes to the quality of the membrane formed surrounding the polymethylmethacrylate (PMMA), in terms of inflammation, proliferation and vasculazition in the Masquelet technique in the early and late phases in a rabbit model. A critical bone defect of 15 mm was created in radius diaphysis, leaving 3 cm of intact bone to the joint. To mimic the Masquelet technique and to increase stability, a 6-hole 1.5 mm plate with two screws was applied, although it was initialy stable because of the inherently fixed ulna and radius both proximally and distally in the rabbits. Group 1 and Group 3, were soleley treated with the Masquelet technique as control groups, and were sacrificed at 3 and 6 weeks, respectively. Group 2 and Group 4, were treated with the Masquelet technique + CGF prepared from the rabbit blood groups, and were sacrificed at 3 and 6 weeks, respectively. The groups were compared histopathologically and immunohistochemically, in respect of the means of thickness of the membrane and ratio of elastic fibers, membrane vascularization (CD31), inflammation (MAC387), proliferation (Ki67), and presence of stem cells (STRO-1). Thickness of the membrane and CD31 values were significantly higher in Group 4 than Group 3 (p = 0.004 for both). MAC387 was statistically significantly higher in Group 2 compared to Group 1 and Group 4 compared to Group 3 (p = 0.04 for both). Ki67 was significantly higher in Group 2 compared to Group 1 and Group 4 compared to Group 3 (p = 0.05 and p = 0.006, respectively). Proliferation in the membrane was statistically significantly higher in Group 2 compared to Group 1 (p = 0.05). Likewise, the proliferation index of Group 4 was statistically significantly higher than Group 3 (p = 0.06). STRO-1 was significantly higher in Group 2 compared to Group 1 (p = 0036). The addition of CGF to the Masquelet technique contributes to the quality of the membrane formed, in respect of inducing inflammation and proliferation, maintaining vascularization on large diaphyseal bone defects, and increasing the number of stem cells.

This study compared the efficacy and safety of oxcarbazepine and divalproex sodium in acute mania patients. In this 12 week, randomized, double-blind pilot study, 60 patients diagnosed with acute mania (DSM-IV) and a baseline Young Mania Rating Scale (YMRS) score of 20 or more received flexibly dosed oxcarbazepine (1,000-2,400 mg/day) or divalproex (750-2,000 mg/day). The mean decrease in the YMRS score from baseline was used as the main outcome measure of response to treatment. A priori protocol-defined threshold scores were or=15 for relapse. Number of patients showing adequate response and the time taken to achieve improvement was compared. Adverse events were systematically recorded throughout the study. Over 12 weeks, mean improvement in YMRS scores was comparable for both the groups including the mean total scores as well as percentage fall from baseline. There were no significant differences between treatments in the rates of symptomatic mania remission (90% in divalproex and 80% in oxcarbazepine group) and subsequent relapse. Median time taken to symptomatic remission was 56 days in divalproex group while it was 70 days in the oxcarbazepine group (p=0.123). A significantly greater number of patients in divalproex group experienced one or more adverse drug events as compared to patients in the oxcarbazepine group (66.7% versus 30%, p<0.01). Oxcarbazepine demonstrated comparable efficacy to divalproex sodium in the management of acute mania. Also the overall adverse event profile was found to be superior for oxcarbazepine.

Objectives: The present study aims to clinically compare and evaluate subepithelial connective tissue graft and the GTR based root coverage in treatment of Miller’s Class I gingival recession. Study Design: 30 patients with at least one pair of Miller’s Class I gingival recession were treated either with Subepithelial connective tissue graft (Group A) or Guided tissue regeneration (Group B). Clinical parameters monitored included recession RD, width of keratinized gingiva (KG), probing depth (PD), clinical attachment level (CAL), attached gingiva (AG), residual probing depth (RPD) and % of Root coverage(%RC). Measurements were taken at baseline, three months and six months. A standard surgical procedure was used for both Group A and Group B. Data were recorded and statistical analysis was done for both intergroup and intragroup. Results: At end of six months % RC obtained were 84.47% (Group A) and 81.67% (Group B). Both treatments resulted in statistically significant improvement in clinical parameters. When compared, no statistically significant difference was found between both groups except in RPD, where it was significantly greater in Group A. Conclusions: GTR technique has advantages over subepithelial connective tissue graft for shallow Miller’s Class I defects and this procedure can be used to avoid patient discomfort and reduce treatment time. Key words:Collagen membrane, comparative split mouth study, gingival recession, subepithelial connective tissue graft, guided tissue regeneration (GTR). PMID:25136420

Many studies have shown the benefits of diathermy over scalpel for making skin incisions in terms of post operative pain and post operative analgesics requirement. The objective of the study is to compare the pain following incision by scalpel and diathermy for skin in ENT surgery. We conducted a prospective, randomized study and compared early post operative pain and analgesics requirement in patients undergoing ENT and Head and Neck surgery in Department of ENT at Kathmandu Medical College from September 2016 to August 2017. The statistical analysis was done using MS Excel and SPSS software. Out of 65 participants, 31 were allocated in scalpel group and 30 were allocated in diathermy group. The mean VAS score was significantly greater in scalpel group as compared to diathermy group in post operative 12, 24 and 48 hours (P<0.05). The mean ketorolac requirement was significantly more in scalpel group than in diathermy group in post operative 24 hours. The early post operative pain is less in ENT-Head and Neck surgery patients with skin incision by diathermy as compared to the patients with skin incision by scalpel.

With the growing rates of travel and, potentially therefore, of travel-related illness in India, this study was conducted to establish both the need of a travelers' clinic in Calcutta and a profile of the group or groups at risk of illness best served by such facilities. A total of 452 visitors, half business and package holiday travelers (group A) and half younger, low-budget tourists with less pretravel advice (group B), were compared. Through a questionnaire, their health, pretravel advice and prophylaxis, use of first aid, safe water use, posttravel treatment, and opinion concerning the need for a travelers' clinic were determined. Group A travelers stayed in deluxe hotels with more pretravel advice (90% compared to 72% in group B), were taking antimalarial agents (82% compared to 61% in group B), remained healthy (72% compared to 58% in group B), consumed safe water (87% compared to 47% in group B), and were more likely to seek posttravel treatment (75% compared to 60% in group B). The group B travelers, consequently, felt an increasing need for a travelers' clinic (92% compared to 82% in group A). Given the complexities of travel in India, there is a palpable need for appropriate medical attention to travelers, especially among the young, budget tourists, which is best provided at a travelers' clinic.

Predictable successful endodontic therapy depends on correct diagnosis, effective cleaning, shaping and disinfection of the root canals and adequate obturation. Irrigation serves as a flush to remove debris, tissue solvent and lubricant from the canal irregularities; however these irregularities can restrict the complete debridement of root canal by mechanical instrumentation.Various types of hand and rotary instruments are used for the preparation of the root canal system to obtain debris free canals. The purpose of this study was to evaluate the amount of smear layer and debris removal on canal walls following the using of manual Nickel-Titanium (NiTi) files compared with rotary ProTaperNiTi files using a Scanning Electron Microscope in two individual groups. A comparative study consisting of 50 subjects randomized into two groups - 25 subjects in Group A (manual) and 25 subjects in Group B (rotary) was undertaken to investigate and compare the effects of smear layer and debris between manual and rotary NiTi instruments. Chi square test was used to find the significance of smear layer and debris removal in the coronal, middle and apical between Group A and Group B. Both systems of Rotary ProTaperNiTi and manual NiTi files used in the present study, did not create completely clean root canals. Manual NiTi files produced significantly less smear layer and debris compared to Rotary ProTaperNiTi instruments. Rotary instruments were less time consuming when compared to manual instruments. Instrument separation was not found to be significant with both the groups. Both systems of Rotary ProTaperNiTi and manual NiTi files used did not produce completely clean root canals. Manual NiTi files produced significantly less smear layer and debris compared to Rotary protaper instruments.

The association between ABO blood groups and intracranial aneurysms is not well-known. Many co-morbid factors are associated with intracranial aneurysms. Our objective was to assess the prevalence of different blood group in patients with intracranial aneurysm and to look for associations between risk factors and these groups. This retrospective study includes 1,491 cases who underwent surgical operations for intracranial aneurysms from 1993-2014. We have evaluated the information related to clinical history, ABO blood groups and associated risk factors in the patients both ruptured and unruptured intracranial aneurysms by chart review of the cases. In our study, out of 1,491 cases, the most common ABO blood groups were group O (668 cases, 44.80%) and Group A (603 cases, 40.44%), and Rh(+) in 1,319 (88.4%) and Rh(-) in 147 (11.6%). Blood Group A (43% vs. 36%) and Group B (16.2% vs. 8.6%) were significantly higher in Caucasian and African Americans respectively. However, in general population, there was no significant difference in blood groups between Caucasians and African Americans. Rh(-) factor was significantly higher in Caucasians compared to African Americans. Incidence of smoking was significantly higher in aneurysm patients with O group compared to others. In addition, incidence of hypercholesterolemia was significantly higher in aneurysm patients with A group compared to others. The racial disparity in the distribution of blood groups, and risk factor association with blood groups in the development of intracranial aneurysm needs to be considered. The findings from our study may be useful in identifying patients at increased risk. Further study may be required to establish the risks from multiple centers studies around the world.

One possible alternative to the application of autologous bone grafts represents the use of autologous bone marrow concentrate (BMC). The purpose of our study was to evaluate the potency of autologous platelet-rich plasma (PRP) in combination with BMC. In 32 mini-pigs a metaphyseal critical-size defect was surgically created at the proximal tibia. The animals were allocated to four treatment groups of eight animals each (1. BMC+CPG group, 2. BMC+CPG+PRP group, 3. autograft group, 4. CPG group). In the BMC+CPG group the defect was filled with autologous BMC in combination with calcium phosphate granules (CPG), whereas in the BMC+CPG+PRP group the defect was filled with the composite of autologous BMC, CPG and autologous PRP. In the autograft group the defect was filled with autologous cancellous graft, whereas in the CPG group the defect was filled with CPG solely. After 6 weeks radiological and histomorphometrical analysis showed significantly more new bone formation in the BMC+CPG+PRP group compared to the BMC+CPG group and the CPG group. There were no significant differences between the BMC+CPG+PRP group and the autograft group. In the PRP platelets were enriched significantly about 4.7-fold compared to native blood. In BMC the count of mononuclear cells increased significantly (3.5-fold) compared to the bone marrow aspirate. This study demonstrates that the composite of BMC+CPG+PRP leads to a significantly higher bone regeneration of critical-size defects at the proximal tibia in mini-pigs than the use of BMC+CPG without PRP. Furthermore, within the limits of the present study the composite BMC+CPG+PRP represents a comparable alternative to autologous bone grafting. PMID:24950251

Background: The aim of this study, we have compared the advantages of oral dydrogestrone with vaginal progesterone (cyclogest) for luteal support in intrauterine insemination (IUI) cycles. Progesterone supplementation is the first line treatment when luteal phase deficiency (LPD) can reasonably be assumed. Objective: This study was conduct to compare the effect of oral dydrogestrone with vaginal Cyclogest on luteal phase support in the IUI cycles. Materials and Methods: This prospective, randomized, double blind study was performed in a local infertility center from May 2013 to May 2014. It consisted of 150 infertile women younger than35years old undergoing ovarian stimulation for IUI cycles. They underwent ovarian stimulation with oral dydrogesterone (20 mg) as group A and vaginal cyclogest (400 mg) as group B in preparation for the IUI cycles. Clinical pregnancy and abortion rates, mid luteal progesterone (7daysafter IUI) and patient satisfaction were compared between two groups. Results: The mean serum progesterone levels was significantly higher in group A in comparison with group B (p=0.001). Pregnancy rates in group A was not statistically different in comparison with group B (p =0.58). Abortion rate in two groups was not statistically different (p =0.056) although rate of abortion was higher in group B in comparison with A group. Satisfaction rates were significantly higher in group A compared to group B (p<0.001). Conclusion: We concluded that oral dydrogestrone is effective as vaginal progesterone for luteal-phase support in woman undergoing IUI cycles. Moreover, the mean serum progesterone levels and satisfaction rates in dydrogestrone group were higher than cyclogest group. PMID:26494991

An ECG is pivotal for the diagnosis of coronary heart disease. Previous studies have reported deficiencies in ECG interpretation skills that have been responsible for misdiagnosis. However, the optimal way to acquire ECG interpretation skills is still under discussion. Thus, our objective was to compare the effectiveness of e-learning and lecture-based courses for learning ECG interpretation skills in a large randomized study. We conducted a prospective, randomized, controlled, noninferiority study. Participants were recruited from among fifth-year medical students and were assigned to the e-learning group or the lecture-based group using a computer-generated random allocation sequence. The e-learning and lecture-based groups were compared on a score of effectiveness, comparing the 95% unilateral confidence interval (95% UCI) of the score of effectiveness with the mean effectiveness in the lecture-based group, adjusted for a noninferiority margin. Ninety-eight students were enrolled. As compared with the lecture-based course, e-learning was noninferior with regard to the postcourse test score (15.1; 95% UCI 14.2; +∞), which can be compared with 12.5 [the mean effectiveness in the lecture-based group (15.0) minus the noninferiority margin (2.5)]. Furthermore, there was a significant increase in the test score points in both the e-learning and lecture-based groups during the study period (both P<0.0001). Our randomized study showed that the e-learning course is an effective tool for the acquisition of ECG interpretation skills by medical students. These preliminary results should be confirmed with further multicenter studies before the implementation of e-learning courses for learning ECG interpretation skills during medical school.

The aim of this 24-week, prospective randomized open-label study was to compare the effects of alogliptin and vildagliptin on glucose control, renal function, and lipid metabolism. In Study 1, DPP-4 inhibitor-naive type 2 diabetes (T2DM) were randomly assigned to alogliptin 25 mg/day or vildagliptin 50 mg twice daily. In Study 2, T2DM on treatment with 50 mg/day sitagliptin were switched to either 25 mg/day alogliptin or 50 mg twice daily vildagliptin. The primary endpoint was change in glycosylated hemoglobin (HbA1c) level at 24 weeks, while the secondary endpoints were changes in urinary albumin excretion and low-density lipoprotein cholesterol (LDL-C) levels at 24 weeks. In Study 1, HbA1c levels changed at 24-week by -0.5±0.7% in the alogliptin group (p=0.002, relative to baseline) and -0.7±0.9% in the vildagliptin group (p=0.001, relative to baseline), and the extent of these changes were comparable between the two groups (p=0.219). The decrease in log urinary albumin excretion was more significant in the vildagliptin group (p=0.008). In Study 2, HbA1c levels at 24-week changed by 0.2±0.7% in the switch-to-alogliptin group (p=0.007) and 0.0±0.6% in the switch-to-vildagliptin group (p=0.188), indicating a significant difference between the groups (p=0.003). In both studies, the changes in LDL-C levels were comparable between the two groups. The two drugs had comparable glucose-lowering effects in DPP-4 inhibitor-naive patients but the effect was more pronounced for vildagliptin in patients switched from sitagliptin. The results may point to subtle yet important differences between the two DPP-4 inhibitors. This trial was registered with UMIN (no. #000019022).

To analyze rectus femoris activity during seated to standing position and walking in water and on dry land comparing a group of children with the spastic diparesis type of cerebral palsy (CP) and a group of children without neurological disorders. This study included a group of nine children with CP and a control group of 11 children. The study compared the electromyographic activity of the rectus femoris during seated to standing position and walking, in water and on land. A greater activation of the rectus femoris was observed in the group of children with CP compared with the control group when moving from a seated position to a standing position in water (p=0.0039) and while walking on land (p=0.0014) or in the pool (p=0.007). This study demonstrated the activation of the rectus femoris while walking or standing up from a seated position in water was greater in the group of children with CP. Further studies should be performed to better understand the extent of muscular activation during body immersion in individuals with neurological disorders. Copyright © 2014 Elsevier Ltd.

Myopia is very common ophthalmic disease especially in children and adolescence. In Ayurvedic texts, only by the main feature impairment of distant vision myopia can be correlated with Drishtigata Rogas (2(nd) Patalgata Timira). To compare the effect of Saptamruta Lauha and Yoga therapy in myopia. In present study, a total 60 patients with age group between 8 to 30 years were selected randomly from the out-patient Department of Swasthavritta and Shalakyatantra Department of Government Ayurveda College, Trivandrum, and were divided in two groups. In Group A, Saptamrita Lauha 250 mg twice daily with unequal quantity of honey and Ghrita was administered while in Group B, patients subjected to Yoga therapy (Jala Neti, Nadi Shodhana, Shitali Pranayama and point Tratak) for 3 months duration with 1 month follow-up. The result obtained from the study reveals that there is no significant reduction in the visual acuity and clinical refraction, but associated changes were observed as reduced in group B when compared to group A. However, relief from headache was found to be equally effective in both the groups.

Electroconvulsive therapy (ECT) is considered to be one of the most effective treatments in psychiatry. Currently, three medications for anesthesia are used routinely during ECT: propofol, etomidate, and thiopental. The objective of this study was to evaluate the effects of the anesthetics used in ECT on seizure threshold and duration, hemodynamics, recovery from ECT, and immediate side effects. Our study is a retrospective cohort study, in which a comparison was made between three groups of patients who underwent ECT and were anesthetized with propofol, etomidate, or thiopental. The main effect compared was treatment dose and seizure duration. All patients were chosen as responders to ECT. Data were gathered about 91 patients (39 were anesthetized with thiopental, 29 with etomidate, and 23 with propofol). Patients in the thiopental group received a lower electrical dose compared to the propofol and etomidate group (mean of 459 mC compared to 807 mC and 701 mC, respectively, P<0.001). Motor seizure duration was longer in the thiopental group compared to propofol and etomidate (mean of 40 seconds compared to 21 seconds and 23 seconds, respectively, P=0.018). Seizure duration recorded by electroencephalography was similar in the thiopental and etomidate groups and lower in the propofol group (mean of 57 seconds in both groups compared to 45 seconds, respectively, P=0.038). Patients who were anesthetized with thiopental received a lower electrical treatment dose without an unwanted decrease in seizure duration. Thiopental might be the anesthetic of choice when it is congruent with other medical considerations.

We have previously reported that intramuscular (IM) therapy with clodronate at a dose of 100 mg/week displays significant effects on bone mineral density (BMD) although a plateau effect is observed after 1 year of treatment. Previous reports indicate that the densitometric effects of bisphosphonates directly correlate with the drug dosage and suggest that using IM clodronate at doses higher than 100 mg/week may result in improved efficacy. However, to the best of our knowledge, this has never been proved. The primary endpoint of the study was the effect on BMD of IM clodronate 100 mg once weekly or 100 mg twice weekly in patients with postmenopausal osteoporosis. The incidence of non-traumatic vertebral fractures and adverse events was also reported. The present study was a randomized, open-label, parallel-group trial conducted between January 2007 and December 2009 in the Osteoporosis and Osteoarticular Instrumental Diagnosis Centre (University of Siena, Siena, Italy). The study involved 60 women, aged 57-78 years, with a history of postmenopausal osteoporosis for more than 5 years. Patients were randomized to receive IM clodronate 100 mg once weekly (Group A, 30 patients) or 100 mg twice weekly (Group B, 30 patients), for 2 years. Significant increases compared with baseline in BMD were observed for both groups at 1 and 2 years, with significantly higher increases for Group B compared with Group A. Group B displayed a BMD increase (± SD) at the lumbar spine of +4.0 % (± 2.1) and +5.9 % (± 2.0) at 1 and 2 year(s), respectively, compared with +2.8 % (± 1.7) and +3.5 % (± 2.2), respectively, observed for Group A. Similarly, Group B showed better performance compared with Group A for BMD increase at the femoral neck, with an observed increase of +3.5 % (± 1.7) and +5.4 % (± 1.8) at 1 and 2 year(s), respectively, compared with a change of +2.3 % (± 1.9) and +2.5 % (± 1.9), respectively, registered in Group A. Consistently, the BMD increase measured at the total femur was significantly higher for Group B [+3.4 % (± 1.9) and +4.9 % (± 2.1) at years 1 and 2, respectively] compared with Group A [+1.6 % (± 0.9) and +2.4 % (± 1.9) at years 1 and 2, respectively]. When the change in BMD from year 1 to year 2 was compared, a significant increase of BMD was seen in Group B in all the analysed regions, contrary to that observed for Group A where a plateau effect resulted in no significant change from year 1 to year 2. Three non-traumatic vertebral fractures occurred during the study: two in Group A and one in Group B. The present study indicates the superior performance of IM clodronate 200 mg weekly (100 mg twice weekly) compared with 100 mg once weekly in BMD in women with postmenopausal osteoporosis. This work demonstrated that administration of twice the drug dosage in a week significantly improved the efficacy of the treatment without inducing serious adverse events. Therefore, IM clodronate 200 mg weekly may be considered a valid therapeutic choice for the treatment of postmenopausal osteoporosis.

Posttraumatic stress disorder (PTSD) is associated with significant impairment and lowered quality of life. The emotional Stroop task (EST) has been one means of elucidating some of the core deficits in PTSD, but this literature has remained inconsistent. We conducted a meta-analysis of EST studies in PTSD populations in order to synthesize this body of research. Twenty-six studies were included with 538 PTSD participants, 254 non-trauma exposed control participants (NTC), and 276 trauma exposed control participants (TC). PTSD-relevant words impaired EST performance more among PTSD groups and TC groups compared to NTC groups. PTSD groups and TC groups did not differ. When examining within-subject effect sizes, PTSD-relevant words and generally threatening words impaired EST performance relative to neutral words among PTSD groups, and only PTSD-relevant words impaired performance among the TC groups. These patterns were not found among the NTC groups. Moderator analyses suggested that these effects were significantly greater in blocked designs compared to randomized designs, toward unmasked compared to masked stimuli, and among samples exposed to assaultive traumas compared to samples exposed to non-assaultive traumas. Theoretical and clinical implications are discussed. Copyright © 2011 Elsevier Ltd. All rights reserved.

The facial skin tone of two groups of Chinese women from Shanghai was compared using standard colorimetric space techniques during a 6-month interval between January and July 2011. During the study period, one group of women (n = 40) applied a potent sun-protective cosmetic product daily, while the other group (n = 40) did not use any sun protection. The results, based on images taken using a standardized digital camera coupled to a spectroradiometer, showed that sun protection largely mitigated changes in the components of skin tone, ie, lightness, melanization, and individual typology angle parameters. The skin darkening process appeared to be reduced or prevented in the sun-protected group when compared with the control group. The sun-protected women had participated in an earlier study in 2008, which confirmed that seasonal skin darkening occurs from winter through summer in Shanghaiese women. Comparing the data obtained in the winters of 2008 and 2011, we were able to identify better the impact of 3 years of aging on the components of skin tone. Comparing data between seasons on the same women with (2011 study) and without (2008 study) sun protection highlights the role of the test product in preventing skin darkening.

Abstract The goal of this study was to systematically review the effects of biliary stenting on postoperative morbidity and mortality of patients with obstructive jaundice. PubMed, Embase, Cochrane Library, and other relevant databases were searched by computer and manually for published and unpublished studies on the impact of preoperative biliary drainage on patients with obstructive jaundice from 2000 to the present day. Two investigators independently selected the studies according to the inclusion and exclusion criteria, extracted the data, and assessed the quality of the selected studies. Meta-analysis was performed to compare postoperative morbidity and mortality of patients between the drainage and nondrainage groups. Compared with the nondrainage group, the overall mortality, overall morbidity, infectious morbidity, incidence of wound infection, intra-abdominal abscess, pancreatic fistulas, bile leak, and delayed gastric emptying in the drainage group were not significantly different. Compared with the nondrainage group, the drainage group had a drainage time of <4 weeks with an increased overall morbidity by 7% to 23%; however, the overall morbidity of the drainage group with a drainage time >4 weeks was not significantly different. Compared with the nondrainage group, the overall mortality of the drainage group using metal stents and plastic stents as internal drainage devices was reduced by 0.5% to 6%, whereas that of the drainage group using plastic stent devices was not significantly different. In summary, preoperative drainage should be applied selectively. The drainage time should be >4 weeks, and metal stents should be used for internal drainage. PMID:25474436

The aim of this study was to evaluate and compare audio and audiovisual distraction aids in management of anxious pediatric dental patients of different age groups and to study children's response to sequential dental visits with the use of distraction aids. This study was conducted on two age groups, that is, 4-6 years and 6-8 years with 30 patients in each age group on their first dental visit. The children of both the age groups were divided into 3 subgroups, the control group, audio distraction group, audiovisual distraction group with 10 patients in each subgroup. Each child in all the subgroups had gone through three dental visits. Child anxiety level at each visit was assessed by using a combination of anxiety measuring parameters. The data collected was tabulated and subjected to statistical analysis. Tukey honest significant difference post-hoc test at 0.05% level of significance revealed audiovisual group showed statistically highly significant difference from audio and control group, whereas audio group showed the statistically significant difference from the control group. Audiovisual distraction was found to be a more effective mode of distraction in the management of anxious children in both the age groups when compared to audio distraction. In both the age groups, a significant effect of the visit type was also observed.

This meta-analysis examined group-design studies investigating the effectiveness of Daily Behavior Report Cards (DBRC) as a school-based intervention to manage the classroom behavior of students with ADHD. A search of three article databases (PsycINFO, ERIC and Medline) identified seven group design evaluations of DBRC interventions. This meta-analysis included a total of 272 participants, with an average age of 7.9 years old. Three of the studies compared a control group to a treatment group with randomized group assignment, one study compared a control group to three treatment groups, two studies compared pre-and post-treatment scores in the same group, and one study compared pre-and post-treatment results of two intervention groups without random assignment. Dependent measures for these studies were teacher ratings (n = 5) and systematic direct observation of student academic and social behaviour (n = 2). Standardized mean differences ( Hedge's g) were calculated to obtain a pooled effect size using fixed effects. DBRCs were associated with reductions teacher-rated ADHD symptoms, with a Hedge's g of 0.36 (95% CI: 0.12-0.60, z=2.93, p ≤ .005) with low heterogeneity (Q-value: 2.40, I 2 = 0.00). This result excluded two studies that used observational coding instead of standardized tests to evaluate the effects of the intervention. A moderator analysis indicated that the effect size for systematic direct observation was large ( Hedge's G = 1.05[95% CI: 0.66-1.44, z=5.25, p ≤ .00]), with very high heterogeneity (Q-value: 46.34, I 2 : 93.53). A second moderator analysis found differences in the effects of DBRCs for comorbid externalizing symptoms with an overall effect size of 0.34 (95%CI: -0.04-0.72, z=1.76 p =0.08) with high heterogeneity (Q-value: 3.98, I 2 : 74.85). DBRCs effectively reduce the frequency and severity of ADHD symptoms in classroom settings. Additionally, they have a significant effect on co-occuring externalizing behaviors. It appears that systematic direct observation may be a more sensitive measure of treatment effects compared to teacher ratings of ADHD symptoms.

Proximal femoral deformities and overcorrection of the acetabulum both can result in secondary femoroacetabular impingement and suboptimal clinical results after periacetabular osteotomy. The purpose of the present study was to determine the rate of complications, the need for reoperations, radiographic correction, and hip function among patients who underwent periacetabular osteotomy and combined femoral head-neck osteochondroplasty as compared with those who underwent periacetabular osteotomy alone. Patients who underwent periacetabular osteotomy with or without osteochondroplasty of the femoral head-neck junction were evaluated retrospectively after a minimum duration of follow-up of two years. We compared the two groups with regard to the modified Harris hip score, radiographic correction, complications, and reoperations. Forty patients (forty hips) who underwent periacetabular osteotomy in conjunction with a femoral head-neck osteochondroplasty were compared with forty-eight patients (forty-eight hips) who underwent an isolated periacetabular osteotomy. Patients were evaluated after a mean duration of follow-up of 3.4 years (range, 2.0 to 9.7 years). Preoperatively, the modified Harris hip score (and standard deviation) was 64.3 ± 13.2 for the study group and 63.2 ± 13.4 for the comparison group. At the time of the latest follow-up, the modified Harris hip score was not significantly different between the study group and the comparison group (p = 0.17). Patients demonstrated equivalent preoperative deformities and postoperative acetabular radiographic parameters. There was a significant decrease in the alpha angle and improvement in head-neck offset in the study group. There was one reoperation for secondary impingement and/or labral pathology in the study group, compared with four reoperations in the comparison group. There were no adhesions requiring surgery, femoral neck fractures, instances of osteonecrosis, or increases in heterotopic ossification in the study group. Femoral head-neck junction osteochondroplasty performed concurrently with a periacetabular osteotomy for the treatment of symptomatic acetabular dysplasia and associated femoral head-neck junction deformities is not associated with an increased complication rate. This combined procedure provides effective correction of associated femoral head-neck deformities and produces similar early functional outcomes when compared with isolated periacetabular osteotomy. Therapeutic Level III.

To evaluate and compare the oral health status and the impact of supervised toothbrushing and oral health education among school children of urban and rural areas of Maharashtra, India. A total of 200 school children in the age group 12-15 years were selected by stratified random sampling technique from two schools and were further divided into two groups: Group A (urban school) and Group B (rural school). Both the groups were again subdivided into control group and study group. Supervised toothbrushing was recommended for both the groups. The toothbrushing teaching program included session on oral health education, individual toothbrushing instructions, and supervised toothbrushing. Dental caries increment, plaque scores, and gingival status were assessed as per the World Health Organization (WHO) criteria (1997), Turesky-Gilmore-Glickman modification of the Quigley Hein Plaque Index, and Loe-Silness Gingival Index (1963), respectively. Cronbach's alpha, Chi-square test, paired t-test, and unpaired t-test were utilized for data analysis. The mean plaque and gingival score reduction was significantly higher in the study groups as compared to the control groups. An increase in the mean of Decayed, missing, filled teeth (DMFT) and Decayed, missing, filled teeth and surfaces (DMFS) scores throughout the study period was seen in children who participated in study. Oral health education was effective in establishing good oral health habits among school children and also in enhancing the knowledge of their parents about good oral health.

Allergic rhinitis (AR) is considered to be a public health problem, therefore it is essential to test health education strategies such as nursing counseling (NC) aimed at population groups such as children with allergic rhinitis and their tutors. This study aimed to measure the health benefits of children with this disease for a year. Longitudinal, randomized, comparative study with a sample of 100 pediatric patients of both sexes, aged 6 to 12 years, with diagnosis of allergic rhinitis, with counseling (study group) and without counseling (control group). In both groups, an informed consent letter signed by both tutors was obtained, in addition to knowledge and assessment papers; the latter included a scale of symptomatology and Morisky Green (adherence to treatment). The children in the study group received intervention based on personalized education, didactic material, support of the multidisciplinary group if necessary (doctor, dermatologist and psychologist). The control group received usual care. In both groups, telephone follow-up was performed, which allowed the number of relapses to be identified in one year. The Wilcoxon rank-sum test (Mann-Whitney) was used to compare the results; the presence of relapses in the control group was statistically significant compared to the study group. It was found that the infant population that receives NC, has as a better benefit the control of the symptomatology and decrease of relapses per year. Copyright © 2017.

The purpose of this study was to compare the pulp testing methods (pulse oximetry and electric pulp test) in primary and young permanent teeth of children. The study included a total of 155 children aged 4 to 15 years. Twenty children formed control group I. Study group included all healthy, 85 primary 2nd molars in group II and 85 permanent 1st molars in group III. Fifty children needing endodontics treatment formed test group IV. The readings were recorded as true positive (TP), false positive (FP), true negative (TN), false negative (FN). Based on this, the sensitivity, specificity, positive predictive value and negative predictive value were calculated for each method. The results were statistically analyzed using Chi-square test. On comparing pulse oximetry with electric pulp test 'p-value' was found to be 0.487 and 1.00 for groups 1 and 2 respectively and was statistically not significant. Whereas 'p-value' for groups 3 and 4 was < 0.0001 and 0.003 respectively and was statistically highly significant. The present study indicates that pulse oximetry can be used as a routine method for assessing the pulp vitality in primary, young permanent and mature permanent teeth.

Background: Epidural opioids acting through the spinal cord receptors improve the quality and duration of analgesia along with dose-sparing effect with the local anesthetics. The present study compared the efficacy and safety profile of epidurally administered butorphanol and fentanyl combined with bupivacaine (B). Materials and Methods: A total of 75 adult patients of either sex of American Society of Anesthesiologist physical status I and II, aged 20-60 years, undergoing lower abdominal under epidural anesthesia were enrolled into the study. Patients were randomly divided into three groups of 25 each: B, bupivacaine and butorphanol (BB) and bupivacaine + fentanyl (BF). B (0.5%) 20 ml was administered epidurally in all the three groups with the addition of 1 mg butorphanol in BB group and 100 μg fentanyl in the BF group. The hemodynamic parameters as well as various block characteristics including onset, completion, level and duration of sensory analgesia as well as onset, completion and regression of motor block were observed and compared. Adverse events and post-operative visual analgesia scale scores were also noted and compared. Data was analyzed using ANOVA with post-hoc significance, Chi-square test and Fisher's exact test. Value of P < 0.05 was considered significant and P < 0.001 as highly significant. Results: The demographic profile of patients was comparable in all the three groups. Onset and completion of sensory analgesia was earliest in BF group, followed by BB and B group. The duration of analgesia was significantly prolonged in BB group followed by BF as compared with group B. Addition of butorphanol and fentanyl to B had no effect on the time of onset, completion and regression of motor block. No serious cardio-respiratory side effects were observed in any group. Conclusions: Butorphanol and fentanyl as epidural adjuvants are equally safe and provide comparable stable hemodynamics, early onset and establishment of sensory anesthesia. Butorphanol provides a significantly prolonged post-operative analgesia. PMID:24843326

This study aimed to evaluate the effect of a diet prepared with traditional sourdough (TS) on iron status. Levels of blood hemoglobin (Hb), Hematocrite (Ht), serum ferritin and serum iron as well as excreted iron were determined in three groups of mice fed with: TS bread (TS group), baking yeast bread (BY group) or bread with no starters (control group), respectively. The results show that the levels of Hb, Ht, ferritin and iron were significantly higher in the TS compared to the BY and control groups. Also a significant decrease in the excreted iron levels was observed in the mice fed with TS compared to the others dietary groups. In conclusion, the study results indicate an improvement of iron status indicators in mice when they were fed sourdough bread as compared to baking yeast bread and bread with no starters.

Adolescent exposure to loud music has become a social and health problem whose study demands a holistic approach. The aims of the current study are: (1) To detect early noise-induced hearing loss among adolescents and establish its relationship with their participation in musical recreational activities and (2) to determine sound immission levels in nightclubs and personal music players (PMPs). The participants consisted in 172 14-15 years old adolescents from a technical high school. Conventional and extended high frequency audiometry, transient evoked otoacoustic emissions and questionnaire on recreational habits were administered. Hearing threshold levels (HTLs) were classified as: normal (Group 1), slightly shifted (Group 2), and significantly shifted (Group 3). The musical general exposure (MGE), from participation in recreational musical activities, was categorized in low, moderate, and high exposure. The results revealed an increase of HTL in Group 2 compared with Group 1 (P < 0.01), in Group 3 compared with Group 2 (P < 0.05) only in extended high frequency range, in Group 3 compared with Group 1 (P < 0.01). Besides, a decrease in mean global amplitude, reproducibility and in frequencies amplitude in Group 2 compared with Group 1 (P < 0.05) and in Group 3 compared with Group 1 (P < 0.05). A significant difference (P < 0.05) was found in Group 1's HTL between low and high exposure, showing higher HTL in high exposure. The sound immission measured in nightclubs (107.8-112.2) dBA and PMPs (82.9-104.6) dBA revealed sound levels risky for hearing health according to exposure times. It demonstrates the need to implement preventive and hearing health promoting actions in adolescents.

To determine whether adjunctive mitomycin C (MMC) or amniotic membrane transplantation (AMT) improve the outcomes of Ahmed glaucoma valve (AGV) implantation. This double-blind, stratified, 3-armed randomized clinical trial includes 75 eyes of 75 patients aged 7 to 75 years with refractory glaucoma. Eligible subjects underwent stratified block randomization; eyes were first stratified to surgery in the superior or inferior quadrants based on feasibility; in each subgroup, eyes were randomly assigned to the study arms using random blocks: conventional AGV implantation (group A, 25 eyes), AGV with MMC (group B, 25 eyes), and AGV with AMT (group C, 25 eyes). The 3 study groups were comparable regarding baseline characteristics and mean follow-up (P=0.288). A total of 68 patients including 23 eyes in group A, 25 eyes in group B, and 20 eyes group C completed the follow-up period and were analyzed. Intraocular pressure was lower in the MMC group only 3 weeks postoperatively (P=0.04) but comparable at other time intervals. Overall success rate was comparable in the 3 groups at 12 months (P=0.217). The number of eyes requiring medications (P=0.30), time to initiation of medications (P=0.13), and number of medications (P=0.22) were comparable. Hypertensive phase was slightly but insignificantly more common with standard surgery (82%) as compared with MMC-augmented (60%) and AMT-augmented (70%) procedures (P=0.23). Complications were comparable over 1 year (P=0.28). Although adjunctive MMC and AMT were safe during AGV implantation, they did not influence success rates or intraocular pressure outcomes. Complications, including hypertensive phase, were also comparable.

Little is known about the relationship between implant patient mortality compared to reference populations. The aim of this study was to report the mortality pattern in patients treated with dental implants up to a 15-year period, and to compare this to mortality in reference populations with regard to age at surgery, sex, and degree of tooth loss. Patient cumulative survival rate (CSR) was calculated for a total of 4,231 treated implant patients from a single clinic. Information was based on surgical registers in the clinic and the National Population Register in Sweden. Patients were arranged into age groups of 10 years, and CSR was compared to that of the reference population of comparable age and reported in relation to age at surgery, sex, and type of jaw/dentition. A similar, consistent, general relationship between CSR of different age groups of implant patients and reference populations could be observed for all parameters studied. Completely edentulous patients presented higher mortality than partially edentulous patients (P < .05). Furthermore, implant patients in younger age groups showed mortality similar to or higher than reference populations, while older patient age groups showed increasingly lower mortality than comparable reference populations for edentulous and partially edentulous patients (P < .05). A consistent pattern of mortality in different age groups of patients compared to reference populations was observed, indicating higher patient mortality in younger age groups and lower in older groups. The reported pattern is not assumed to be related to implant treatment per se, but is assumed to reflect the variation in general health of a selected subgroup of treated implant patients compared to the reference population in different age groups.

Correcting crooked nose deformity is one of the most difficult procedure in rhinoplastic surgery. For that reason, the authors have been designed an asymmetrically pressing nasal splint. In this prospective study, the aim was to compare the effects of applying asymmetrically pressing nasal splint and normal symmetrically splint on the crooked nose. This study included 129 patients who were operated on for crooked nose deformity. Patients were divided into 2 groups. Normal symmetrically pressing nasal splint was applied to groups 1a (I type) and 1b (C type). Asymmetrically pressing nasal splint was applied to groups 2a (I type) and 2b (C type). All groups were compared according to deflection angle from the midline, the percentage of postoperative improvement, patient satisfaction with visual analog scale, and complication rate. I-type noses in both groups at postoperative angle values were reduced, and C-type noses in both groups at postoperative angle values were increased significantly compared with preoperative values. I-type noses of group 2 at postoperative angle values compared with group 1 were reduced, and C-type noses were increased in group 2 significantly. Patient satisfaction rate in group 2 were significantly better than in group 1. The closeness ratios to the ideal angles in group 1 were in "good" and "moderate" levels, whereas in group 2, it was in "excellent" level. There was no significant difference in complication rate in both groups. Asymmetrically pressing splint (novel design) showed increasing success rate clearly in crooked nose surgery than in normal splints.

Study Design: Retrospective clinical study. Objectives: The aim of this study was to compare intraoperative conditions and clinical results of patients undergoing pre-psoas oblique lateral interbody fusion (OLIF) using navigation or conventional fluoroscopy (C-ARM) techniques. Methods: Forty-two patients (22 patients by navigation and 20 by fluoroscopy) underwent the OLIF procedure at 2 medical centers, and records were reviewed. Clinical data was collected and compared between the 2 groups. Patients were followed-up with a range of 6 to 24 months. Results: There were no significant differences on demographic data between groups. The navigation group had zero radiation exposure (RE) to the surgeon and radiation time compared to the C-ARM group, with total RE of 44.59 ± 26.65 mGy and radiation time of 88.30 ± 58.28 seconds (P < .05). The RE to the patient was significantly lower in the O-ARM group (9.38 mGy) compared to the C-ARM group (44.59 ± 26.65 mGy). Operating room time was slightly longer in the navigation group (2.49 ± 1.35 hours) compared to the C-ARM group (2.30 ± 1.17 hours; P > .05), although not statistically significant. No differences were found in estimated blood loss, length of hospitalization, surgery-related complications, and outcome scores with an average of 8-month follow-up. Conclusions: Compared with C-ARM techniques, using navigation can eliminate RE to surgeon and decrease RE to the patient, and it had no significant effect on operating time, estimated blood loss, length of hospitalization, or perioperative complications in the patients with OLIF procedure. This study shows that navigation is a safe alternative to fluoroscopy during the OLIF procedure in the treatment of degenerative lumbar conditions. PMID:28989845

To evaluate the efficacy of autologous platelet rich plasma (PRP) in regeneration of bone and to assess clinical compatibility of the material in mandibular third molar extraction socket. To compare the healing of mandibular third molar extraction wounds with and without PRP. Group A consists of the 30 patients where PRP will be placed in the extraction socket before closure of the socket. Group B consists of 30 patients who will be the control group where the extraction sockets will be closed without any intra socket medicaments. The patients would be allocated to the groups randomly. Soft tissue healing was better in study site compared to control site. The result of the study shows rapid bone regeneration in the extraction socket treated with PRP when compared with the socket without PRP. Evaluation for bone blending and trabecular bone formation started earlier in PRP site compared to control, non PRP site. Also there was less postoperative discomfort on the PRP treated side. Autologous PRP is biocompatible and has significant improved soft tissue healing, bone regeneration and increase in bone density in extraction sockets.

Our aim was to assess the long-term outcome for minor forefoot amputations. A retrospective study of 126 patients who had such amputations between 1999 and 2004 was performed. Patients were divided into 2 groups, diabetic (group A: 79 patients) and nondiabetic (group B: 47 patients). Angiograms were requested in 45 patients in group A compared with 31 patients in group B (P = ·77). In group A, 11 patients underwent further ipsilateral amputations compared with 30 patients in group B (P = ·02.). The 2 groups were equally likely to have vascular reconstruction (35% vs 37%). The overall 5-year mortality was 27%, with 58% of deaths occurring within the first year. This study shows that foot amputees have high mortality and reintervention rates. Adequate utilization of vascular services, extra vigilance in the prevention of complications, and risk factor modifications are required to improve postoperative outcomes.

This project studied the lowering blood lipids effect in atherosclerotic ApoE-deficient mice. Group A mice (n = 6), fed with a normal diet, served as the negative control. The experimental groups used mice fed with a high cholesterol diet (HCD) for eight weeks, and then selected for inclusion in the study on the basis of high blood lipid levels and the formation of atherosclerotic lesion plaque, which was indicated by an ultrasound biomicroscopy test. Eighteen mice met the selection criteria (atherosclerotic mice with high blood lipid levels) and these were randomly assigned into three groups B, C and D (n = 6). Group B fed with a HCD, served as the positive control. The intervention Group C was fed with HCD and Simvastatin. The intervention Group D was fed with a HCD and Hawthorn fruit compound (HFC includes Hawthorn and Kiwi fruit extract) for eight weeks. The results showed that after feeding on a HCD, Group B had significantly higher blood lipid levels compared to Group A and this confirmed the validity of Group A and Group B controls in this study. The results also showed that compared to Group B, in both Group C and D, there was a significant reduction in triglyceride and in the ratio between low-density lipoprotein cholesterol (LDL-C) and serum cholesterol. Moreover a reduction of LDL-C was evident in Group D, whereas a similar effect did not occur in Group C. The results indicate that HFC can be considered for the treatment of hyperlipidemia and prevention of atherosclerosis.

Chronic diseases can act as an accelerating factor in the auditory system degeneration. Studies on the association between presbycusis and diabetes mellitus and systemic arterial hypertension have shown controversial conclusions. To compare the initial audiometry (A1) with a subsequent audiometry (A2) performed after a 3 to 4-year interval in a population of elderly patients with diabetes mellitus and/or systemic arterial hypertension, to verify whether hearing loss in these groups is more accelerated when compared to controls without these clinical conditions. 100 elderly individuals participated in this study. For the auditory threshold assessment, a previous complete audiological evaluation (A1) and a new audiological evaluation (A2) performed 3-4 years after the first one was utilized. The participants were divided into four groups: 20 individuals in the diabetes mellitus group, 20 individuals in the systemic arterial hypertension group, 20 individuals in the diabetes mellitus/systemic arterial hypertension group and 40 individuals in the control group, matching them with each study group, according to age and gender. ANOVA and Kruskal-Wallis statistical tests were used, with a significance level set at 0.05. When comparing the mean annual increase in the auditory thresholds of the A1 with the A2 assessment, considering each study group and its respective control, it can be observed that there was no statistically significant difference for any of the frequencies for the diabetes mellitus group; for the systemic arterial hypertension group, significant differences were observed after 4kHz. For the diabetes mellitus and systemic arterial hypertension group, significant differences were observed at the frequencies of 500, 2kHz, 3kHz and 8kHz. It was observed that the systemic arterial hypertension group showed the greatest decrease in auditory thresholds in the studied segment when compared to the other groups, suggesting that among the three studied conditions, hypertension seems to have the greatest influence on hearing.

Using inquiry-based instructional strategies in third-grade science

NASA Astrophysics Data System (ADS)

Harris, Fanicia D.

The purpose of the study was to determine if the use of inquiry-based instructional strategies as compared to traditional instructional strategies would increase third-grade students' achievement in science, based on the pretest/posttest of the school system and the Georgia Criterion-Referenced Competency Test (CRCT). Inquiry-based instruction, presented students with a question, an observation, a data set, or a hypothesis for problem solving such as scientists use when working in real-world situations. This descriptive research employed a quantitative strategy using a pretest/posttest control group design. The research compared the science academic achievement levels of one Grade 3 class [N=14] exposed to a teacher's inquiry-based instructional strategies as compared to one Grade 3 class [ N=18] exposed to a teacher's traditional instructional strategies. The study compared the science academic performance levels of third-grade students as measured by pretest/posttest mean scores from the school system-based assessment and the Georgia CRCT. Four research hypotheses were examined. Based on the overall findings from this study, both the experimental group and the control group significantly increased their mean scores from the pretests to the posttests. The amount of gain from the pretest to the posttest was significantly greater for the experimental group than the control group for pretest/posttest 1 [t(12) = 8.79, p < .01] and pretest/posttest 2 [t(12) = 9.40, p < .01]. The experimental group significantly outperformed the control group with regard to their mean number of items answered correctly on the life sciences test [t(27) = -1.95, p = .06]. Finally, the control group did not outperform the experimental group on any of the comparisons made throughout this study. The results of this study provide empirical support for the effectiveness of the use of inquiry-based learning strategies, given that the experimental group outperformed the control group on all four posttests, on the science CRCT and on the individual Science portions on the test including earth, life and physical sciences. In fact, this study was able to detect significant differences between the experimental group and the control group with regard to the degree to which the students improved from the pretests to the posttests.

Minimally invasive surgery is being used increasingly, including for hallux valgus surgery. Despite the growing interest in minimally invasive procedures, there have been few publications on percutaneous chevron/akin (PECA) procedures, and no studies have been published comparing PECA to open scarf/akin osteotomies (SA). This was a prospective, randomized study of 50 patients undergoing operative correction of hallux valgus using one of 2 techniques (PECA vs open SA). Data were collected preoperatively and on 1 day, 2 weeks, 6 weeks, and 6 months postoperatively. Outcome measures include the American Orthopaedic Foot & Ankle Society Hallux-Metatarsophalangeal-Interphalangeal (AOFAS-HMI) Score, visual analog pain score, hallux valgus angle (HVA), and 1-2 intermetatarsal angle (IMA). Twenty-five patients underwent PECA procedures and 25 patients received SA procedures. Both groups showed significantly improved AOFAS-HMI scores after surgery (PECA group: 61.8 to 88.9, SA group: 57.3 to 84.1, P = .560) with comparable final scores. HVA and IMA also presented similar outcomes at final follow-up ( P = .520 and P = .270, respectively). However, the PECA group showed significantly lower pain level (VAS) in the early postoperative phase (postoperative day 1 to postoperative week 6, P < .001 and P = .004, respectively). No serious complications were observed in either group. Both groups showed comparable good to excellent clinical and radiologic outcomes at final follow-up. However, the PECA group had significantly less pain in the first 6 weeks following surgery. Level of Evidence Level II, prospective comparative study.

Background and aims Given the similarities in clinical symptoms, Internet gaming disorder (IGD) is thought to be diagnostically similar to Internet-based gambling disorder (ibGD). However, cognitive enhancement and educational use of Internet gaming suggest that the two disorders derive from different neurobiological mechanisms. The goal of this study was to compare subjects with ibGD to those with IGD. Methods Fifteen patients with IGD, 14 patients with ibGD, and 15 healthy control subjects were included in this study. Resting-state functional magnetic resonance imaging data for all participants were acquired using a 3.0 Tesla MRI scanner (Philips, Eindhoven, The Netherlands). Seed-based analyses, the three brain networks of default mode, cognitive control, and reward circuitry, were performed. Results Both IGD and ibGD groups demonstrated decreased functional connectivity (FC) within the default-mode network (DMN) (family-wise error p < .001) compared with healthy control subjects. However, the IGD group demonstrated increased FC within the cognitive network compared with both the ibGD (p < .01) and healthy control groups (p < .01). In contrast, the ibGD group demonstrated increased FC within the reward circuitry compared with both IGD (p < .01) and healthy control subjects (p < .01). Discussion and conclusions The IGD and ibGD groups shared the characteristic of decreased FC in the DMN. However, the IGD group demonstrated increased FC within the cognitive network compared with both ibGD and healthy comparison groups.

The aim of the present study was to compare three different forms of exercises namely lumbar stabilization, dynamic strengthening, and Pilates on chronic low back pain (LBP) in terms of pain, range of motion, core strength and function. In this study, 44 subjects suffering from non-specific LBP for more than 3 months were randomly allocated into the lumbar stabilization group, the dynamic strengthening group, and the Pilates group. Ten sessions of exercises for 3 weeks were prescribed along with interferential current and hot moist pack. Pain was assessed by visual analog scale, functional affection by modified Oswestry Disability Questionnaire, range of motion by assessing lumbar flexion and extension by modified Schober test and core strength was assessed by pressure biofeedback on day 1 and day 10 of the treatment. There was reduction of pain, improvement in range of motion, functional ability and core strength in all the 3 exercise groups. The improvement was significantly greater in the lumbar stabilization group for all the outcome measures, when compared the posttreatment after 10th session. Pairwise comparison showed that there was greater reduction of disability in the Pilates group than the dynamic strengthening group. It was concluded that the lumbar stabilization is more superior compared to the dynamic strengthening and Pilates in chronic nonspecific LBP. However, long-term benefits need to be assessed and compared with prospective follow-up studies. PMID:29114516

This retrospective cohort study evaluated the cumulative live birth rate in women with polycystic ovary syndrome (PCOS) and isolated polycystic ovaries (PCO) undergoing in-vitro fertilisation (IVF) treatment. We studied 104 women with PCOS, 184 with PCO and 576 age-matched controls undergoing the first IVF treatment cycle between 2002 and 2009. The main outcome measure was cumulative live birth in the fresh plus all the frozen embryo transfers combined after the same stimulation cycle. Women in both the PCOS (n = 104) and isolated PCO groups (n = 184) had higher ovarian response parameters compared to age-matched controls (n = 576), and higher rates of withholding fresh embryo transfer for risk of ovarian hyperstimulation syndrome (OHSS). The actual incidence of moderate to severe OHSS was significantly higher in the PCOS (11.5 %) but not the isolated PCO group (8.2%) compared to controls (4.9%). The live birth rates in the fresh cycle were comparable among the 3 groups, but the PCOS group had a significantly higher miscarriage rate compared to the other 2 groups. Cumulative live birth rate was significantly higher in the isolated PCO group (60.3%), but not the PCOS group (50.0%), compared to controls (47.5%). Women in the isolated PCO group, but not the PCOS group, had a significantly higher cumulative live birth rate compared to controls. This could be explained by the quantitative effect of the higher number of transferable embryos obtained per stimulation cycle, which is uncompromised by the unfavourable embryo competence otherwise observed in PCOS.

The immune system of neonates has been considered functionally immature, and due to their high susceptibility to infections, the aim of this study was to analyse the phenotypic differences in leucocyte populations in healthy preterm and full-term newborns. We evaluated the absolute numbers and frequencies of dendritic cells (DCs) and DC subsets, monocytes and T and B lymphocytes and subsets in the cord blood of healthy moderate and very preterm (Group 1), late preterm (Group 2) and full-term (Group 3) newborns and in healthy adults, as controls, by flow cytometry. The analyses revealed statistically higher absolute cell numbers in neonates compared with adults due to the characteristic leucocytosis of neonates. We observed a lower frequency of CD80(+) myeloid and plasmacytoid DCs in Group 1 and reduced expression of TLR-4 on myeloid DCs in all neonates compared with adults. TLR-2(+) monocytes were reduced in Group 1 compared with Groups 2 and 3, and TLR-4(+) monocytes were reduced in Groups 1 and 2 compared with Group 3. The frequencies and numbers of naïve CD4(+) T and CD19(+) B cells were higher in the three groups of neonates compared with adults, while CD4(+) effector and effector memory T cells and CD19(+) memory B cells were elevated in adults compared with neonates, as expected. Our study provides reference values for leucocytes in cord blood from term and preterm newborns, which may facilitate the identification of immunological deficiencies in protection against extracellular pathogens. © 2014 John Wiley & Sons Ltd.

Objective: C-reactive protein (CRP) is an acute-phase reactant and has been proved to be a significant predictor of future cardiovascular events. Recent studies have demonstrated a correlation between periodontitis and elevated CRP levels. However, most of the studies have focused on chronic periodontitis and very few studies are done in patients with aggressive periodontitis. The aim of this study was to determine and compare the relative levels of serum CRP in aggressive and chronic periodontitis patients. Materials and Methods: A total of 75 systemically healthy subjects were divided into three groups: Group I, nonperiodontitis subjects; group II, chronic generalized periodontitis patients and group III, generalized aggressive periodontitis patients. All participants were subjected to quantitative CRP analysis using enzyme-linked immunosorbent assay. Results: Mean CRP levels were significantly greater in both group II and III as compared to group I and group III having greater level than group II. Furthermore, CRP levels positively correlated with the amount of periodontal destruction as measured by probing depth and clinical attachment loss. Conclusion: The present study indicates a positive correlation between CRP and periodontal disease severity with particular concern in younger individuals that could be a possible underlying pathway in the association between periodontal disease and the observed higher risk for cardiovascular disease in periodontitis patients.

This study compares the immunogenicity and safety of a single dose of a new meningococcal A conjugate vaccine (PsA-TT, MenAfriVac™, Serum Institute of India Ltd., Pune) against the meningococcal group A component of a licensed quadrivalent meningococcal polysaccharide vaccine (PsACWY, Mencevax ACWY(®), GSK, Belgium) 28 days after vaccination in Indian children. This double-blind, randomized, controlled study included 340 Indian children aged 2-10 years enrolled from August to October 2007; 169 children received a dose of PsA-TT while 171 children received a dose of PsACWY. Intention-to-treat analysis showed that 95.2% of children in PsA-TT group had a ≥4-fold response in serum bactericidal titers (rSBA) 28 days post vaccination as compared to 78.2% in the PsACWY group. A significantly higher rSBA GMT (11,209, 95%CI 9708-12,942) was noted in the PsA-TT group when compared to PsACWY group (2838, 95%CI 2368-3401). Almost all children in both vaccine groups had a ≥4-fold response in group A-specific IgG concentration but the IgG GMC was significantly greater in the PsA-TT group (89.1 μg/ml, 95%CI 75.5-105.0) when compared to the PsACWY group (15.3 μg/ml, 95%CI 12.3-19.2). Local and systemic reactions during the 4 days after immunization were similar for both vaccine groups except for tenderness (30.2% in PsA-TT group vs 12.3% in PsACWY group). None of the adverse events or serious adverse events was related to the study vaccines. We conclude that MenAfriVac™ is well tolerated and significantly more immunogenic when compared to a licensed polysaccharide vaccine, in 2-to-10-year-old Indian children.

Impact on learning of an e-learning module on leukaemia: a randomised controlled trial

PubMed Central

2012-01-01

Background e-learning resources may be beneficial for complex or conceptually difficult topics. Leukaemia is one such topic, yet there are no reports on the efficacy of e-learning for leukaemia. This study compared the learning impact on senior medical students of a purpose-built e-learning module on leukaemia, compared with existing online resources. Methods A randomised controlled trial was performed utilising volunteer senior medical students. Participants were randomly allocated to Study and Control groups. Following a pre-test on leukaemia administered to both groups, the Study group was provided with access to the new e-learning module, while the Control group was directed to existing online resources. A post-test and an evaluation questionnaire were administered to both groups at the end of the trial period. Results Study and Control groups were equivalent in gender distribution, mean academic ability, pre-test performance and time studying leukaemia during the trial. The Study group performed significantly better than the Control group in the post-test, in which the group to which the students had been allocated was the only significant predictor of performance. The Study group’s evaluation of the module was overwhelmingly positive. Conclusions A targeted e-learning module on leukaemia had a significant effect on learning in this cohort, compared with existing online resources. We believe that the interactivity, dialogic feedback and integration with the curriculum offered by the e-learning module contributed to its impact. This has implications for e-learning design in medicine and other disciplines. PMID:22640463

Objective: The aim of this study was to compare the results of monotherapy (photodynamic therapy) and combined therapy (photo-dynamic therapy with posterior sub-Tenon triamcinolone acetonide) in age-related macular degeneration (AMD). Materials and Methods: Forty eyes from forty patients with diagnosed neovascular AMD were enrolled in this study during March-2005 – October-2008. All patients were grouped in either the study or the control group. Both the study and control groups consisted of 20 eyes from 20 patients. The study group was treated with posterior sub-Tenon triamcinolone acetonide (PSTA) along with their initial photodynamic therapy (PDT) treatment. The control group members were treated with PDT alone. All patients were examined at 1, 3, 6 and 12 months. Visual acuity (VA), lesion size and number of treatment sessions were recorded during each examination. Results: The mean difference between pre- and post-treatment VA using the Snellen chart was +0.6 ± 1.7 in study group and −1.4 ± 1.7 in control. The difference for VA was significant in the study group as compared to control (p<0.05). The decrease in lesion size in the study group was 680±1195.2 µm, and the decrease was 32.75 ± 809.9 µm in the control. The difference with regard to the decrease in lesion sizes was significant in the study group as compared to the control (p<0.05). Total PDT treatment sessions were applied 1.2 times per patient in the study group and 1.9 times per patient in the control group. The difference was not significant (p>0.05). Conclusion: Our study showed that PSTA with PDT significantly reduces CNV growth, and improves VA at the 12-month follow-up in patients with AMD. PMID:25610041

Background: Hypobaric spinal anesthesia is advantageous for unilateral lower extremity fractures as it obviates pain of lying on fractured limb for performing subarachnoid block. Aims: This study compares block characteristics and complications of three different baricities of constant dose intrathecal hypobaric levobupivacaine to determine an optimum baricity. Settings and Design: One-twenty American Society of Anesthesiologists Physical Status 1 and 2 patients aged 18–65 years undergoing unilateral lower limb surgeries were divided into three equal groups for this prospective cohort study. Materials and Methods: To 2 mL intrathecal 0.5% isobaric levobupivacaine (10 mg), 0.4 mL, 0.6 mL, and 0.8 mL of distilled water were added in Groups A, B, and C, respectively. Baricities of Groups A, B, and C are 0.999294, 0.998945, and 0.998806, respectively. Development of sensory and motor block was assessed by the pinprick method and Bromage scale, respectively. The total duration of analgesia and complications were noted. Statistical Analysis Used: Mean, standard error, one-way ANOVA, and Bonferroni were used to analyze quantitative variables; proportions and Chi-square tests for qualitative variables. Results: Demographic parameters, motor block of operated limb, and complications were comparable. Group C had the fastest onset of sensory block (10.10 min) and maximum duration of analgesia (478.97 min; P < 0.001); but high sensory levels in 48.7%. Group B had T10 sensory level in 92.5%; onset comparable to Group C (P = 0.248), and reasonable duration of analgesia (332.50 min). Group A had inadequate sensory levels, slow onset, and early regression. Conclusions: Group B (baricity - 0.998945) has better block characteristics among three groups compared. PMID:28928563

The impact of hypertonic saline (HTS) on long term control of intracranial hypertension (ICH) is yet to be established. The current prospective randomized controlled study was carried out in 38 patients with severe traumatic brain injury (TBI). Over 450 episodes of refractory ICH were treated with equiosmolar boluses of 20% mannitol in 20 patients and 3.0% HTS in 18 subjects. Intracranial pressure (ICP) was monitored for 6days. ICP and cerebral perfusion pressure (CPP) were comparable between the groups. The mannitol group had a progressive increase in the ICP over the study period (p=0.01). A similar increase was not seen in the HTS group (p=0.1). The percentage time for which the ICP remained below a threshold of 20 mmHg on day6 was higher in the HTS group (63% versus 49%; p=0.3). The duration of inotrope requirement in the HTS group was less compared to the mannitol group (p=0.06). The slope of fall in ICP in response to a bolus dose at a given baseline value of ICP was higher with HTS compared to mannitol (p=0.0001). In-hospital mortality tended to be lower in the HTS group (3 versus 10; p=0.07) while mortality at 6 months was not different between the groups (6 versus 10; p=0.41). Dichotomized Glasgow Outcome Scale scores at 6months were comparable between the groups (p=0.21). To conclude, immediate physiological advantages seen with HTS over mannitol did not translate into long term benefit on ICP/CPP control or mortality of patients with TBI.

This study aims to investigate the efficiency of a single and repeated greater occipital nerve (GON) block using lidocaine in the treatment of triptan-overuse headache (TOH), whose importance has increased lately. In the study, 105 consecutive subjects diagnosed with TOH were evaluated. The subjects were randomized into three groups. In Group 1 (n=35), only triptan was abruptly withdrawn. In Group 2 (n=35), triptan was abruptly withdrawn and single GON block was performed. In Group 3 (n=35), triptan was abruptly withdrawn and three-stage GON block was performed. All patients were injected bilaterally with a total amount of 5 cc 1% lidocaine in each stage. During follow-up, the number of headache days per month, the severity of pain (VAS), the number of triptans used, and hsCRP and IL-6 levels were recorded three times; in the pretreatment period, in the second month post-treatment, and in the fourth month post-treatment. They were then compared. There was a statistically significant difference in the post-treatment fourth month in comparison with the pretreatment period in Group 3 (P<.05). Compared to Group 1, the number of headache days, VAS, and decrease in triptan need in Group 3 was statistically significant compared to Group 2 (P<.05). Compared to pretreatment, in the fourth month post-treatment, both hsCRP and IL-6 levels were lower only in Group 3 (P<.05). We are of the opinion that repeated GON block in addition to the discontinuation of medication has significant efficacy for TOH cases. © 2016 John Wiley & Sons A/S.

Objective The objective of this study was to assess outcomes of childhood systemic lupus erythematosus (cSLE) in three different age groups evaluated at last visit: group A early-onset disease (<6 years), group B school age (≥6 and <12 years) and group C adolescent (≥12 and <18 years). Methods An observational cohort study was performed in ten pediatric rheumatology centers, including 847 cSLE patients. Results Group A had 39 (4%), B 395 (47%) and C 413 (49%). Median disease duration was significantly higher in group A compared to groups B and C (8.3 (0.1-23.4) vs 6.2 (0-17) vs 3.3 (0-14.6) years, p < 0.0001). The median Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SLICC/ACR-DI) (0 (0-9) vs 0 (0-6) vs 0 (0-7), p = 0.065) was comparable in the three groups. Further analysis of organ/system damage revealed that frequencies of neuropsychiatric (21% vs 10% vs 7%, p = 0.007), skin (10% vs 1% vs 3%, p = 0.002) and peripheral vascular involvements (5% vs 3% vs 0.3%, p = 0.008) were more often observed in group A compared to groups B and C. Frequencies of severe cumulative lupus manifestations such as nephritis, thrombocytopenia, and autoimmune hemolytic anemia were similar in all groups ( p > 0.05). Mortality rate was significantly higher in group A compared to groups B and C (15% vs 10% vs 6%, p = 0.028). Out of 69 deaths, 33/69 (48%) occurred within the first two years after diagnosis. Infections accounted for 54/69 (78%) of the deaths and 38/54 (70%) had concomitant disease activity. Conclusions This large multicenter study provided evidence that early-onset cSLE group had distinct outcomes. This group was characterized by higher mortality rate and neuropsychiatric/vascular/skin organ damage in spite of comparable frequencies of severe cumulative lupus manifestations. We also identified that overall death in cSLE patients was an early event mainly attributed to infection associated with disease activity.

To investigate the clinical effect of Saccharomyces boulardii powder combined with azithromycin sequential therapy in the treatment of children with diarrhea secondary to Mycoplasma pneumoniae pneumonia. A total of 88 children with diarrhea secondary to Mycoplasma pneumoniae pneumonia between June 2015 and March 2017 were divided into control group and study group using a random number table, with 44 children in each group. The children in the control group were given routine treatment combined with azithromycin sequential therapy, and those in the study group were given oral Saccharomyces boulardii powder in addition to the treatment in the control group until the end of azithromycin sequential therapy. After the treatment ended, the two groups were compared in terms of time to improvement of clinical symptoms, length of hospital stay, clinical outcome, defecation frequency before and after treatment, condition of intestinal dysbacteriosis, and incidence of adverse events. Compared with the control group, the study group had significantly shorter time to improvement of clinical symptoms and length of hospital stay (P<0.05). The study group had a significantly higher response rate than the control group (P<0.05). On days 3 and 5 of treatment, the study group had a significant reduction in defecation frequency compared with the control group (P<0.05). The study group had a significantly lower rate of intestinal dysbacteriosis than the control group (P<0.05). There was no significant difference in the incidence of adverse events between the two groups (P>0.05). In the treatment of children with diarrhea secondary to Mycoplasma pneumoniae pneumonia, Saccharomyces boulardii powder combined with azithromycin sequential therapy can improve clinical symptoms, shorten the length of hospital stay, reduce defecation frequency and the incidence of intestinal dysbacteriosis, and improve clinical outcomes, and does not increase the risk of adverse events.

This study investigated the effectiveness of mindfulness-based group therapy (MBGT) compared to the usual opioid dependence treatment (TAU).Thirty outpatients meeting the DSM-IV-TR criteria for opioid dependence from Iranian National Center for Addiction Studies (INCAS) were randomly assigned into experimental (Mindfulness-Based Group Therapy) and control groups (the Usual Treatment).The experimental group undertook eight weeks of intervention, but the control group received the usual treatment according to the INCAS program. The Five Factor Mindfulness Questionnaire (FFMQ) and the Addiction Sevier Index (ASI) were administered at pre-treatment and post-treatment assessment periods. Thirteen patients from the experimental group and 15 from the control group completed post-test assessments. The results of MANCOVA revealed an increase in mean scores in observing, describing, acting with awareness, non-judging, non-reacting, and decrease in mean scores of alcohol and opium in MBGT patient group. The effectiveness of MBGT, compared to the usual treatment, was discussed in this paper as a selective protocol in the health care setting for substance use disorders.

The prevalence of ABO alleles is different in different populations, and many studies have shown a correlation between the occurrences of some diseases and different genotypes of ABO blood groups. The aim of this study was to determine whether there is a significant association between psychiatric syndromes and ABO blood groups. This case-control study involved 156 psychiatric patients and 303 healthy, unrelated, voluntary blood donors. Genomic DNA was isolated from blood on a QIAcube device using a QIAamp DNA Blood mini QIAcube kit. ABO genotyping on five basic ABO alleles was performed using allele-specific polymerase chain reaction analysis. Compared with healthy subjects, a significantly higher proportion of psychiatric patients had AB blood group (χ 2 =9.359, df=3, p=0.025) and, accordingly, a significantly higher incidence of A1B genotype (χ 2 =8.226, df=3, p=0.042). The odds ratio showed that psychiatric disorders occur almost three times more frequently in carriers of AB group compared to other blood groups. However, no statistically significant difference was found in the distribution of ABO blood groups among patients with different psychiatric diagnoses. Likewise, no correlations were found between ABO blood groups and other characteristics of the psychiatric patients (sex, psychiatric heredity, somatic comorbidity, suicidality). The results of this study support the hypothesis of an association between psychiatric disorders and ABO blood groups. The probability is that psychiatric disorders will occur almost three times more frequently in carriers of AB group compared to other ABO blood groups in the Croatian population.

To compare the efficacy and safety profiles of sorafenib and apatinib in patients with intermediate- and advanced-stage hepatocellular carcinoma (HCC). This was a single-center, retrospective study where we collected the clinical data of 72 patients, diagnosed with intermediate or advanced HCC from January 2014 to December 2016. Depending on the treatment received, 38 patients were categorized into group S (sorafenib group) and 34 into group A (apatinib group). The patients in group A received the initial recommended dose of 750 mg once daily (QD), which was reduced to 250 mg QD in the case of any class 3 or 4 adverse event (AE). Sorafenib was administered orally 400 mg twice daily (BID), and dose was modified to 400 mg or 200 mg QD in the case of grade 3 or 4 AEs. The median overall survival (OS), progression-free survival (PFS), and AEs reported in the two groups were analyzed and compared. Among the 38 patients treated with sorafenib, one patient had complete response (CR), 5 patients had partial response (PR), and 10 patients had stable disease (SD), and among the 34 patients treated with apatinib, 6 patients had PR and 7 patients had SD with no cases of CR. PFS in group S was significantly longer compared with that in group A (7.39 vs 4.79 months, respectively, P =0.031). Similar observations were made for median OS (10.4 months in group S vs 7.18 months in group A, P =0.011). However, there was no significant difference in the objective response rates (ORRs) among the study population (15.7 vs 17.6%, P =0.829). Common AEs in group S included hand and foot syndrome (HFS) and diarrhea, whereas common AEs in group A included hypertension, proteinuria, and increased transaminase. Our study showed promising clinical outcome with apatinib, but the sorafenib group exhibited better clinical efficacy with no significant difference in safety profile.

Background and Aims: Bupivacaine is available in isobaric and hyperbaric forms for intrathecal use and opioids are used as additives to modify their effects. The aim of this study was to compare the efficacy and haemodynamic effect of intrathecal isobaric bupivacaine-fentanyl mixture and hyperbaric bupivacaine-fentanyl mixture in common urological procedures. Methods: One hundred American Society of Anesthesiologists physical status 1 and 2 patients undergoing urological procedures were randomized into two groups. Group 1 received 3 ml of 0.5% isobaric bupivacaine with 25 μg fentanyl while Group 2 received 3 ml of 0.5% hyperbaric bupivacaine with 25 μg fentanyl. The parameters measured include heart rate, blood pressure, respiratory rate, onset and duration of motor and sensory blockade. Student's unpaired t-test and the χ2 test were used to analyse the results, using the SPSS version 11.5 software. Results: The haemodynamic stability was better with isobaric bupivacaine fentanyl mixture (Group 1) than with hyperbaric bupivacaine fentanyl mixture (Group 2). The mean onset time in Group 1 for both sensory block (4 min) and motor block (5 min) was longer compared with Group 2. The duration of sensory block (127.8 ± 38.64 min) and motor block (170.4 ± 27.8 min) was less with isobaric bupivacaine group compared with hyperbaric bupivacaine group (sensory blockade 185.4 ± 16.08 min and motor blockade 201.6 ± 14.28 min). Seventy percent of patients in Group 2 had maximum sensory block level of T6 whereas it was 53% in Group 1. More patients in Group 1 required sedation compared to Group 2. Conclusion: Isobaric bupivacaine fentanyl mixture was found to provide adequate anaesthesia with minimal incidence of haemodynamic instability. PMID:26962255

Background Alpha-2 adrenergic agonists produce safe and effective analgesia, but most investigations studying the analgesic effect of alpha-2 adrenoceptor agonists postoperatively included previous or concomitant administration of other analgesics. Because clonidine potentiates the effect of these drugs, its own intrinsic analgesic effect has been difficult to establish. This study was designed to compare the intraoperative and postoperative effects of epidural clonidine vs bupivacaine for patients undergoing lower abdominal surgery. Methods This randomized controlled trial included 40 patients aged 18-50 who were scheduled for elective lower abdominal surgery. Patients were randomly divided into 2 groups. Group I (n=20) received epidural clonidine; Group II (n=20) received epidural bupivacaine. Intraoperative and postoperative hemodynamics, pain scores, and complications were monitored. Results Mean pain scores were significantly lower in Group I compared to Group II (1.5 ± 0.5 compared to 3.4 ± 1.0, respectively) in the first 12 hours after surgery. Sedation was more prominent in Group I until 9 hours after surgery. Opioid requirements were significantly lower in Group I. Respiratory rate was similar in the 2 groups. Group I had larger decreases from baseline in systolic blood pressure and diastolic blood pressure than Group II. Heart rate in Group I was reduced from baseline, while it was increased in Group II. Less postoperative nausea and vomiting, urinary retention, pruritus, and shivering were observed in Group I. Conclusion Compared to bupivacaine, epidural clonidine provided effective intraoperative and postoperative analgesia in selected patients, resulting in a decreased intravenous pain medication requirement and prolonged duration of analgesia after epidural infusion was discontinued.

Superior rectus transposition (SRT) with medial rectus recession has been used for the treatment of sixth nerve palsy and esotropic Duane retraction syndrome (DRS). The purpose of this study was to compare the results of augmented SRT (with scleral fixation) without medial rectus recession in DRS and sixth nerve palsy. Patients with unilateral esotropic DRS (DRS group) and sixth nerve palsy were included in this prospective, comparative study and underwent SRT. Preoperative forced duction testing was negative or slightly positive in both groups. Prospective measurements were compared between the two groups. There were 11 patients in the DRS group and 11 patients in the sixth nerve palsy group. The mean preoperative esotropia decreased from 20.9 ± 6.0 prism diopter (PD) at far to 13.2 ± 5.8 PD in the DRS group (P = 0.003). The same measurement improved from 28.0 ± 8.5 PD to 8.4 ± 7.3 PD in the sixth nerve palsy group (P = 0.003). In the sixth nerve palsy group, the improvement in primary gaze esotropia and abnormal head posture was more than the DRS group (Both P < 0.001).The average dose effect for SRT was 7.8 ± 2.2 PD in the DRS group and 19.2 ± 4.6 PD in the sixth nerve palsy group. Although objective intorsion was significantly induced after SRT, subjective torsion was not significant after surgery in both groups. SRT appears to be more effective in improving primary gaze deviation and head posture in sixth nerve palsy compared with DRS. Subjective torsional and vertical diplopia were rare in both groups.

To investigate dry eye development in the patients receiving systemic retinoic acid therapy and to compare effectiveness of Autologous Serum (AS) and preservative free artificial tear (PFAT) in the patients with dry eye disease. This prospective, crossover, double blind study was conducted on patients who have dry eyes due to systemic isotretinoin treatment for different indications. Patients detected as having dry eye during systemic isotretinoin treatment were included to our study. At baseline, 1 and 2 month of study, detailed ocular examination, best corrected visual acuity measurement, intraocular pressure measurement, and Tear Break-up Time (TBUT) and Schirmer Test (ST) without topical anesthesia were performed. We compared the efficacy of AS and PFAT. To accomplish crossover after the first month, treatment given to each patient was switched to the other treatment. Statistical analysis was measured using SPSS version 20.0. p values of < 0.05 were considered as statistically significant. At the end of the first month, there was a significant improvement for the TBUT test in both AS and PFAT groups compared to baseline (respectively p < 0.001, p < 0.001). TBUT was found to be significantly higher in the AS group compared to the PFAT group at the end of the first month (p < 0.001). At the end of the second month, TBUT was found to be significantly higher in the AS group compared to the PFAT group at the posttreatment time (p < 0.001). There was a significant OSDI score decreasing in both groups compared to that reported previously at the end of the first and second months (respectively p < 0.001, p < 0.001). OSDI score decreasing was more significant in the AS group compared to the PFAT group at both time points (respectively p < 0.001, p < 0.001). AS may be an effective alternative to PFAT in the treatment of dry eye developed during isotretinoin use.

The transgenerational transmission of mental disorders is one of the most prominent risk factors for the development of psychological disorders. Children of mentally ill parents are a vulnerable high risk group with overall impaired development and high rates of psychological disorders. To date there are only a few evidence based intervention programs for this group overall and hardly any in Germany. We translated the evidence based Family Talk Intervention by Beardslee (2009) and adapted it for groups. First results of this pilot study are presented. This investigation evaluates a preventive group intervention for children of mentally ill parents. In a quasi-experimental design three groups are compared: an intervention group (Family Talk Intervention group: n = 28), a Wait Control group (n = 9), and a control group of healthy children (n = 40). Mean age of children was 10.41 years and parental disorders were mostly depressive/affective disorders (n = 30), but a small number also presented with Attention-Deficit/Hyperactivity Disorder (n = 7). Children of mentally ill parents showed higher rates of internalizing/externalizing disorders before and after the intervention compared to children of parents with no disorders. Post intervention children's knowledge on mental disorders was significantly enhanced in the Family Talk Intervention group compared to the Wait Control group and the healthy control group. Parental ratings of externalizing symptoms in the children were reduced to normal levels after the intervention in the Family Talk Intervention group, but not in the Wait Control group. This pilot study of a group intervention for children of mentally ill parents highlights the importance of psycho-education on parental mental disorders for children. Long-term effects of children's enhanced knowledge about parental psychopathology need to be explored in future studies.

The aim of this in vitro study was to compare the efficacy of two retreatment rotary systems in the removal of Gutta-percha (GP) and sealer from the root canal walls with or without solvent. Forty-eight extracted human mandibular first premolars were prepared and obturated with GP and AH Plus sealer. Samples were then randomly divided into four groups. Group I was retreated with MtwoR rotary system without solvent, Group II was retreated with MtwoR rotary system with Endosolv R as the solvent, Group III with D-RaCe rotary system without solvent, and Group IV with D-RaCe rotary system and Endosolv R solvent. The cleanliness of canal walls was determined by stereomicroscope (×20) and AutoCAD software. Kruskal-Wallis test and Mann-Whitney U-test were used to compare the data. Results showed that none of the retreatment systems used in this study was able to completely remove the root canal filling material. D-RaCe with or without solvent showed significantly ( P > 0.05) less filling material at all levels compared to MtwoR with/without solvent. Within the limitation of the current study, D-RaCe rotary retreatment system is more effective in removing filling material from root canal walls when compared to MtwoR rotary retreatment system.

The rapid improvements in medical sciences and the ever-increasing related data, however, require novel methods of instruction. One such method, which has been given less than due attention in Iran, is problem-based learning (PBL). In this study, we aimed to evaluate the impact of study skills and the PBL methods on short and long-term retention of information provided for medical students in the course of respiratory physiology and compare it with traditional learning method. In this study, 39 medical students from Medical School of Kerman University of Medical Sciences, Kerman, Iran (2006-2010) were enrolled in the study and allocated randomly in three equal groups (13 in each group). All groups underwent a pre-test to be assessed for their basic information regarding respiratory physiology. Two groups were instructed using the traditional method, and one group used PBL. Among the two groups of the traditional method, one was instructed about study skills and the other was not. Once the PBL group took the study skill workshop, they were aided by tutors for their education. In the final term test, those students who had learned study skills and were instructed with the traditional method scored higher compared to other groups (p < 0.05). However, in the 1 year (p < 0.05) and 4 year (p < 0.01) interval examinations, the PBL group achieved significantly higher scores. Despite the fact that PBL had no positive effect on the final term exam of our students, it yielded a more profound and retained understanding of the subject course. Moreover, considering the positive effect of study skills on long-term student scores, we recommend students to receive instructions regarding the appropriate study skills when initiated into universities.

In the literature, studies of computer-assisted total knee arthroplasty (TKA) after mid-term period are not conclusive and long-term data are rare. In a prospective, randomized, comparative study 100 conventional TKAs (group REG) were compared with 100 computer-assisted TKAs (group NAV). Minimum follow-up was 5years. No difference in implant failure was found with 1.1% in group NAV versus 4.6% in group REG (P=0.368). Group NAV showed a significantly less mean deviation of mechanical limb axis (P=0.015), more TKAs (90% versus 81% in group REG) were within 3° varus/valgus and a higher tibial slope and lateral distal femoral angle (LDFA) accuracy was found (P≤0.034). Clinical investigational parameters showed no differences (P≥0.058). Insall and HSS score total were also higher in group NAV (P≤0.016). Copyright © 2014 Elsevier Inc. All rights reserved.

2011-01-01

Research on anger attacks has been mostly limited to unipolar depression, and only a few studies have focused on anger attacks in bipolar depression. In a cross-sectional study, 22 subjects with bipolar depression were compared to 22 subjects with recurrent unipolar depression using an anger attack questionnaire, irritability, depression and anxiety scale and quality of life scale. Anger attacks were present in 62.5% subjects with recurrent depression (RDD group) compared to 54.5% in subjects with bipolar depression (BD group), but the difference between the groups was not statistically significant. Also, there was no significant difference between the RDD and BD groups on the Irritability Depression and Anxiety Scale and WHOQOL-Bref except that the BD group had a poorer quality of life (QOL) compared to the RDD group in the social relationship domain (t=-2.30, p<0.05). In the BD group, the subjects with anger attacks were older (t=2.77, p<0.05), had significantly higher scores on the Irritability-Outwards component of IDA (t=3.90, p<0.01) and shorter duration of illness (Mann Whitney Signed ranked value 20.00, p<0.01) and duration of treatment (Mann Whitney Signed ranked value 28.00, p<0.05) compared to BD group members without anger attacks. In the RDD group, the subjects with anger attacks had poor QOL in the social domain (t= -2.12, p<0.05), environmental domain (t=2.99, p=.01) and total (t=2.56, p<0.05) QOL compared to those without anger attacks. Anger attacks are equally prevalent in unipolar and bipolar depression, are not influenced by sociodemographic and clinical variables, and lead to comparable impact on the subjective QOL in both groups.

To study influence of abstinence period on the live-birth rate after assisted reproductive technology (ART). Retrospective cohort study. Reproductive medicine unit, university-level hospital. A total 1,030 ART cycles evaluated from 2011 to 2015. Group I, abstinence period 2-7 days, and group II, abstinence period >7 days, were compared. Two subgroups Ia (2-4 days) and Ib (5-7 days) were also compared with group II. Primary outcome was live birth per ET. Secondary outcomes included implantation, clinical pregnancy, and miscarriage rates. The live-birth rate (34.1 % vs. 24.1%; odds ratio [OR], 1.6; 95% confidence interval [CI], 1.1-2.4), clinical pregnancy rate (44.4 % vs. 32.7%; OR, 1.6; 95% CI, 1.1-2.3), and implantation rate (26.4% vs. 18.2%) were significantly higher in group I compared with group II. Other secondary outcomes of fertilization rate and miscarriage rate did not differ between groups I and II. The adjusted odds ratio (aOR) for live birth (aOR, 1.6; 95% CI, 1.1-2.5) and clinical pregnancy rates (aOR, 1.7; 95% CI, 1.2-2.5) were significantly higher for group I compared with group II. The live-birth rate was significantly higher in group Ia (36.1% vs. 24.1%) compared with group II. An abstinence period of more than 7 days may impact ART outcomes adversely when compared with an abstinence period of 2-7 days. Copyright © 2017 American Society for Reproductive Medicine.

Objective To evaluate whether hemostasis with eletrocauterization in comparison with Floseal(r) leads to different bleeding rates during total knee arthroplasty. Methods A comparative study was performed between two groups: group with ten consecutive total knee arthroplasties with Floseal(r) used as hemostatic method and control group with ten consecutive total knee arthroplasties with eletrocauterization as hemostatic method. Bleeding parameters such as debit of the drain, liquid infusion and blood transfusion rate were recorded. Results Floseal(r) group received less blood transfusion, less liquid infusion and lower drainage in absolute numbers compared to the control group. However, no parameter was statistically significant. Conclusion Hemostasis with Floseal(r) is as effective as hemostasis with eletrocauterization, what makes it a viable alternative to patients with contraindication to electric scalpel use.

Ankylosing spondylitis (AS) is a chronic, inflammatory rheumatic disease. Physiotherapy is considered an important part of the overall management of AS. To summarise the available scientific evidence on the effectiveness of physiotherapy interventions in the management of AS. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, AMED, CINAHL and PEDro up to January 2007 for all relevant publications, without any language restrictions. We checked the reference lists of relevant articles and contacted the authors of included articles. We included randomised and quasi-randomised studies with AS patients and where at least one of the comparison groups received physiotherapy. The main outcomes of interest were pain, stiffness, spinal mobility, physical function and patient global assessment. Two reviewers independently selected trials for inclusion, extracted data and assessed trial quality. Investigators were contacted to obtain missing information. Eleven trials with a total of 763 participants were included in this updated review. Four trials compared individualised home exercise programs or a supervised exercise program with no intervention and reported low quality evidence for effects in spinal mobility (Relative percentage differences (RPDs) from 5-50%) and physical function (four points on a 33-point scale). Three trials compared supervised group physiotherapy with an individualised home-exercise program and reported moderate quality evidence for small differences in spinal mobility (RPDs 7.5-18%) and patient global assessment (1.46 cm) in favour of supervised group exercises. In one study, a three-week inpatient spa-exercise therapy followed by 37 weeks of weekly outpatient group physiotherapy (without spa) was compared with weekly outpatient group physiotherapy alone; there was moderate quality evidence for effects in pain (18%), physical function (24%) and patient global assessment (27%) in favour of the combined spa-exercise therapy. One study compared daily outpatient balneotherapy and an exercise program with only exercise program, and another study compared balneotherapy with fresh water therapy. None of these studies showed significant between-group differences. One study compared an experimental exercise program with a conventional program; statistically significant change scores were reported on nearly all spinal mobility measures and physical function in favour of the experimental program. The results of this review suggest that an individual home-based or supervised exercise program is better than no intervention; that supervised group physiotherapy is better than home exercises; and that combined inpatient spa-exercise therapy followed by group physiotherapy is better than group physiotherapy alone.

The fit of interim crowns fabricated using 3-dimensional (3D) printing is unknown. The purpose of this in vitro study was to evaluate the fit of interim crowns fabricated using photopolymer-jetting 3D printing and to compare it with that of milling and compression molding methods. Twelve study models were fabricated by making an impression of a metal master model of the mandibular first molar. On each study model, interim crowns (N=36) were fabricated using compression molding (molding group, n=12), milling (milling group, n=12), and 3D polymer-jetting methods. The crowns were prepared as follows: molding group, overimpression technique; milling group, a 5-axis dental milling machine; and polymer-jetting group using a 3D printer. The fit of interim crowns was evaluated in the proximal, marginal, internal axial, and internal occlusal regions by using the image-superimposition and silicone-replica techniques. The Mann-Whitney U test and Kruskal-Wallis tests were used to compare the results among groups (α=.05). Compared with the molding group, the milling and polymer-jetting groups showed more accurate results in the proximal and marginal regions (P<.001). In the axial regions, even though the mean discrepancy was smallest in the molding group, the data showed large deviations. In the occlusal region, the polymer-jetting group was the most accurate, and compared with the other groups, the milling group showed larger internal discrepancies (P<.001). Polymer-jet 3D printing significantly enhanced the fit of interim crowns, particularly in the occlusal region. Copyright © 2016 Editorial Council for the Journal of Prosthetic Dentistry.

Background A pain-free postoperative period is essential following a caesarean section so new mothers may care for and bond with their neonates. Intrathecal adjuvants are often administered during this procedure to provide significant analgesia, but they may also have bothersome side effects. Intrathecal midazolam produces effective postoperative analgesia with no significant side effects. Objectives This prospective, randomized, double-blind study was designed to compare the analgesic efficacy and safety of intrathecal midazolam vs. plain bupivacaine as an adjunct to bupivacaine in pregnancy-induced hypertension patients scheduled for elective caesarean section. Methods Sixty patients diagnosed with pregnancy-induced hypertension on regular treatment who were scheduled for a caesarean section were randomly allocated into two groups: a control group (Group BC, n = 30) and a midazolam group (Group BM, n = 30). Both groups received 10 mg (2 mL) of 0.5% hyperbaric bupivacaine. Group BC received 0.4 mL of distilled water, while group BM received 0.4 mL (2 mg) of midazolam intrathecally. The duration of postoperative analgesia, analgesic requirements during the first 24 hours after surgery, onset times and durations of sensory and motor blocks, incidence of hypotension, vasopressor requirements, and side effects were recorded. Results Postoperative analgesia was significantly longer in the midazolam group compared to the control group (201.5 minutes vs. 357.6 minutes). The mean onset times of the sensory and motor blocks were significantly faster (P < 0.01) in the midazolam group compared to the control group. The mean times to attain the maximum sensory level and motor blocks were also significantly faster in the midazolam group compared to the control group (P < 0.05). The incidence of hypotension was 6.6% in the midazolam group and 36.6% in the control group, which was highly significant. In addition, the number of patients with side effects was significantly lower in the midazolam group compared to the control group. Conclusions Intrathecal midazolam 2 mg provides significantly longer and effective postoperative analgesia with no side effects. PMID:27847698

To compare the clinical outcome of pterygium surgery combining intraoperative mitomycin C (MMC) with a free conjunctival autograft, with three other methods of pterygium surgery, including intraoperative MMC alone, conjunctival autograft alone, and bare sclera without adjunctive treatment. Interventional, randomized and in part nonrandomized, prospective, comparative study. setting: A university medical center department of ophthalmology. One hundred and twenty patients underwent pterygium excision surgery. These patients were divided into four treatment groups. In group 1 (30 patients), MMC, 0.2 mg/ml, was applied for three minutes. In group 2 (30 patients), conjunctival autografting was performed. Group 3 (30 patients) received sodium chloride 0.9% only, and group 4 (30 patients) underwent conjunctival autografting combined with one minute application of MMC, 0.2 mg/ml. Recurrence rates and complications. Pterygium recurred in two patients (6.6%) in group 1, in four patients (13.3%) in group 2, in 14 patients (46.6%) in group 3, and in none of the patients in group 4. chi(2) analysis revealed a significantly lower recurrence rate in group 4 compared with group 2 (P = .038) and with group 3 (P < .0001). Epithelialization of the wounds was complete within 14 days of surgery. No complications were demonstrated in any of the study groups except for one case of minor melting of the flap in group 4. This study indicates that pterygium excision with a free conjunctival autograft combined with intraoperative low-dose MMC is a safe and effective technique in pterygium surgery.

The 24-week equivalent efficacy and comparable safety results of the biosimilar SB5 and reference adalimumab (ADA) from the phase III randomized study in patients with moderate-to-severe rheumatoid arthritis (RA) have been reported previously. We undertook this transition study to evaluate patients who switched from ADA to SB5 or who continued to receive SB5 or ADA up to 52 weeks. In this phase III study, patients were initially randomized 1:1 to receive SB5 or ADA (40 mg subcutaneously every other week). At 24 weeks, patients receiving ADA were rerandomized 1:1 to continue with ADA (ADA/ADA group) or to switch to SB5 (ADA/SB5 group) up to week 52; patients receiving SB5 continued with SB5 for 52 weeks (SB5 group). Efficacy, safety, and immunogenicity were evaluated up to 52 weeks. The full analysis set population consisted of 542 patients (269 in the SB5 group, 273 in the ADA overall group [patients who were randomized to receive ADA at week 0], 125 in the ADA/SB5 group, and 129 in the ADA/ADA group). The percentages of patients meeting the American College of Rheumatology 20%, 50%, or 70% improvement criteria (achieving an ACR20, ACR50, or ACR70 response) at week 24 were maintained after the transition from ADA to SB5, and these response rates were comparable across treatment groups throughout the study. ACR20 response rates ranged from 73.4% to 78.8% at week 52. Radiographic progression was minimal and comparable across treatment groups. The safety profile and the incidence of antidrug antibodies were comparable across treatment groups after transition. SB5 was well tolerated over 1 year in patients with RA, with efficacy, safety, and immunogenicity comparable to those of ADA. Switching from ADA to SB5 had no treatment-emergent issues such as increased adverse events, increased immunogenicity, or loss of efficacy. © 2018 The Authors.

Previous studies have found mixed results about cigarette and alcohol consumption patterns among rural-to-urban migrants. Moreover, there are limited longitudinal data about consumption patterns in this population. As such, this study aimed to compare the smoking and heavy drinking prevalence among rural, urban, and rural-to-urban migrants in Peru, as well as the smoking and heavy drinking incidence in a 5-year follow-up. We analyzed the PERU MIGRANT Study data from rural, urban, and rural-to-urban migrant populations in Peru. The baseline study was carried out in 2006-2007 and follow-up was performed five years later. For the baseline data analysis, the prevalence of lifetime smoking, current smokers, and heavy drinking was compared by population group using prevalence ratios (PR) and 95% confidence intervals (95% CI). For the longitudinal analysis, the incidence of smoking and heavy drinking was compared by population group with risk ratios (RR) and 95% CI. Poisson regression with robust variance was used to calculate both PRs and RRs. We analyzed data from 988 participants: 200 rural dwellers, 589 migrants, and 199 urban dwellers. Compared with migrants, lifetime smoking prevalence was higher in the urban group (PR = 2.29, 95% CI = 1.64-3.20), but lower in the rural group (PR = 0.55, 95% CI = 0.31-0.99). Compared with migrants, the urban group had a higher current smoking prevalence (PR = 2.29, 95% CI = 1.26-4.16), and a higher smoking incidence (RR = 2.75, 95% CI = 1.03-7.34). Current smoking prevalence and smoking incidence showed no significant difference between rural and migrant groups. The prevalence and incidence of heavy drinking was similar across the three population groups. Our results show a trend in lifetime smoking prevalence (urban > migrant > rural), while smoking incidence was similar between migrant and rural groups, but higher in the urban group. In addition, our results suggest that different definitions of smoking status could lead to different smoking rates and potentially different measures of association. The prevalence and incidence of heavy drinking were similar between the three population groups.

Oxidative stress and reduced microvascular flow are important factors in the pathogenesis of inflammatory bowel disease (IBD). The increased oxidative stress reduces the erythrocyte deformability. However, in IBD, there are no studies in the literature which evaluate erythrocyte deformability. In our study, we investigated the effect of oxidative stress and erythrocyte deformability in IBD. Forty-three patients with active IBD, 48 patients with inactive IBD and 45 healthy controls were included. The erytrocyte deformability, malonyldialdehyde levels, glutation peroxidase and sulfhydryl levels were measured in peripheral venous blood samples. Erytrocyte malonyldialdehyde levels in both active and inactive IBD were significantly increased compared with control groups. Plasma glutation peroxidase levels did not show statistically significant difference between all groups. The decreased plasma sulfhydryl levels in active IBD were statistically significant compared with both the inactive IBD and the control group, but plasma sulfhydryl levels in inactive IBD group did not show statistically significant differences when compared with the control group. Elongation index values in both active and inactive IBD increased significantly compared with the control group. Statistically significant correlations were not found between the elongation index and glutation peroxidase, malonyldialdehyde, sulfhydryl levels in all groups. Our study is the first to evaluate the erythrocyte deformability in IBD. In our study, increased erytrocyte malonyldialdehyde levels and decreased plasma sulfhydryl levels manifested the role of oxidative stress in the pathogenesis of the disease. It is thought that the increased erythrocyte malonyldialdehyde values cause the reduction in erythrocyte deformability.

A significant correlation between hypertension history and high blood pressure has been observed with regard to age, race and gender. Investigating carotid intima-media thickness and aortic stiffness prior to the development of hypertension in children of hypertensive parents enabled us to evaluate these patients for subclinical atherosclerosis. We compared carotid intima-media thickness, aortic strain, distensibility, stiffness indices and elastic modulus in 67 normotensive children whose parents had a diagnosis of essential hypertension and 39 normotensive children with no parental history of hypertension. Although there were no significant differences between the two groups in terms of systolic blood pressure, diastolic blood pressure, average blood pressure and pulse pressure (P>0.05), systolic blood pressures were higher among patients 15 years and older in the study group. No significant differences were noted between the control and study groups regarding interventricular septal thickness, left-ventricular posterior wall thickness, left-ventricular systolic and diastolic diameter and aortic annulus diameter (P>0.05). The left atrium diameter was larger in the study group compared with that in the control group, mainly because of the values of the 15-year-old and older children (P=0.01). The mean, maximum and minimum values of carotid intima-media thickness were significantly different in the study group compared with the control group among all age groups (P<0.001, P<0.001, P=0.006, respectively). Aortic systolic and diastolic diameters were larger in normotensive children of hypertensive parents compared with the control group (P=0.014, P=0.001, respectively). Although there were no differences between the study and control groups regarding aortic strain, aortic distensibility, elastic modulus and stiffness indices (P>0.05), aortic distensibility was lower, and aortic stiffness indices were higher among children 15 years and older in the study group. An increase in the carotid intima-media thickness in all age groups and a decrease in aortic elastic properties in 15-year-old and older children of hypertensive parents may indicate subclinical atherosclerosis in these apparently healthy children.

Alexithymia is characterised by difficulties identifying and describing emotions. Few studies have investigated how alexithymia influences decision-making under different conditions (ambiguity and risk). This study aimed to examine whether alexithymia contributes to impairment in decision-making. This study included 42 participants with high scores in the Chinese version of Toronto Alexithymia Scale (alexithymia group), and 44 matched subjects with low scores (control group). Decision-making was measured using the Iowa Gambling Task (IGT) and the Game of Dice Task (GDT). The main findings of this study revealed selective deficits in IGT performance for the alexithymia group, while GDT performance was unimpaired when compared with the control group. In IGT, total netscores were lower for the alexithymia group compared to the control group, particularly with regard to block 5. Moreover, the alexithymia individuals selected significantly more adverse cards than the controls, indicating significant decision-making impairments. Alexithymia selectively influences decision-making under ambiguity.

Acupuncture has been used for patients with stroke and post-stroke rehabilitation for thousands of years. Previous studies reported that acupuncture enhanced stroke recovery through neurogenesis. Hence, we conducted a systematic review and meta-analysis for preclinical studies to assess the current evidence for acupuncture effect on neurogenesis in treating ischaemic stroke. Studies were obtained from six databases, including PubMed, EMBASE, Cochrane Library, Chinese National Knowledge Infrastructure, VIP information database, and Chinese Biomedical Literature Database, Ultimately, 34 studies containing 1617 animals were identified. Neurogenesis markers of Brdu, Nestin, PSA-NCAM, NeuN and GFAP were selected as major outcomes. The pooled results of 15 studies marked with Brdu showed significant effects of acupuncture for improving proliferation when compared with control groups (P < 0.01); 13 studies marked with Nestin showed significant effects of acupuncture for increasing proliferation when compared with control groups (P < 0.01); 4 studies marked with PSA-NCAM showed significant effects of acupuncture for enhancing migration when compared with control groups (P < 0.01); 4 studies marked with NeuN showed significant effects of acupuncture for stimulating differentiation when compared with control groups (P < 0.01). The findings suggest that acupuncture is a prospective therapy targeting neurogenesis for ischemic stroke.

In 2009-2010 Sydney Water, the primary water utility in Sydney, conducted a comprehensive Smart Metering trial in residential homes in the suburb of Westleigh, in Sydney's north. The trial involved 1923 participants residing in 630 households. A whole-of-community method of engagement was applied to capture the views of residents from 12 to 70+ years of age. The trial examined the effects of the technology on the water consumption of an intervention group compared with that of a matched control group. After removing properties that had been sold since the beginning of the trial, properties in the study group were matched with a control group property on the basis of the household size, property size and the presence (or otherwise) of a swimming pool. The effects of the technology on consumption were measured and analyzed for the period July 2009 to June 2010, coupled with qualitative information that was collected throughout the duration of the study. A key finding was that households with the in-home display (IHD) installed, reduced their consumption by an average of over 6.8% over the study period when compared to the control group. Since completion of the study the community has not had any further interventions. The trial created an opportunity to examine the longer-term effects of the technology (June 2008 to September 2013). Consumption data collected over the 3 year posttrial period revealed that the participant group consumed 6.4% per month less water when compared to the pretrial period, whilst the matched control group consumed 1.3% per month more water when compared to the pretrial period. The reduced consumption of the participant group was maintained over time, demonstrating the long-term value of this technology.

Introduction Training emergency care skills is critical for patient safety but cost intensive. Serious games have been proposed as an engaging self-directed learning tool for complex skills. The objective of this study was to compare the cognitive skills and motivation of medical residents who only used a course manual as preparation for classroom training on emergency care with residents who used an additional serious game. Methods This was a quasi-experimental study with residents preparing for a rotation in the emergency department. The “reading” group received a course manual before classroom training; the “reading and game” group received this manual plus the game as preparation for the same training. Emergency skills were assessed before training (with residents who agreed to participate in an extra pretraining assessment), using validated competency scales and a global performance scale. We also measured motivation. Results All groups had comparable important characteristics (eg, experience with acute care). Before training, the reading and game group felt motivated to play the game and spent more self-study time (+2.5 hours) than the reading group. Game-playing residents showed higher scores on objectively measured and self-assessed clinical competencies but equal scores on the global performance scale and were equally motivated for training, compared with the reading group. After the 2-week training, no differences between groups existed. Conclusions After preparing training with an additional serious game, residents showed improved clinical competencies, compared with residents who only studied course material. After a 2-week training, this advantage disappeared. Future research should study the retention of game effects in blended designs. PMID:27764018

Biofilm formation occurs commonly on urinary catheters. To assess the efficacy of urinary catheters coated with sustained-release varnish of chlorhexidine in decreasing catheter-associated biofilm formation in dogs. Thirty client-owned dogs. Prospective study. Thirteen dogs were catheterized with urinary catheters coated with sustained-release varnish of chlorhexidine (study group), and 13 dogs were catheterized with an untreated urinary catheter (control group). Presence and intensity of biofilm formation on the urinary catheters were assessed and compared between the groups by evaluating colony-forming units (CFU) of biofilm bacteria, and semiquantitatively, using confocal laser scanning microscopy and electron microscopy. None of the dogs experienced adverse effects associated with the presence of the urinary catheters. Median CFU count of biofilm bacteria at all portions of the urinary catheter was significantly (P < .001) lower in the study compared with the control group. The degree of biofilm formation on the urinary catheters, as evaluated by confocal laser scanning microscopy and electron microscopy, was significantly lower in the study compared with the control group. Electron microscopy examination identified crystals on some of the urinary catheters. The proportion of catheters on which crystals were observed was significantly lower on the distal part of the urinary catheter in the study group compared with the control group (16.7% versus 66.7%, respectively; P = .04). Chlorhexidine sustained-release varnish-coated urinary catheters effectively decrease urinary catheter-associated biofilm formation in dogs.

Study Objective: This is a population-based longitudinal study that followed insomnia symptoms over a 6-year period in non-depressed individuals. The purpose of the study was to (1) investigate the longitudinal course of depression based on number of insomnia episodes; and (2) describe longitudinal associations between insomnia and depression, and insomnia and suicidal ideation. Design: Population-based longitudinal study. Setting: Community-based sample from the Korean Genome and Epidemiology Study (KoGES). Participants: 1,282 non-depressed individuals (44% male, mean age 52.3 ± 7.14 years) Measurements and Results: This study prospectively assessed insomnia, depression, and suicidal ideation with 4 time points. Individuals were classified into no insomnia (NI), single episode insomnia (SEI), and persistent insomnia (PI; ≥ insomnia at 2+ time points) groups based on number of times insomnia was indicated. Mixed effects modeling indicated that depression scores increased significantly faster in the PI group compared to the NI (P < 0.001) and SEI (P = 0.02) groups. Additionally, the PI group had significantly increased odds of depression as compared to NI or SEI (OR 2.44, P = 0.001) groups, with 18.7% meeting criteria for depression compared to the NI (5.3%) and SEI (11.6%) groups at end point. The PI group also had significantly increased odds of suicidal ideation as compared to NI or SEI (OR 1.86, P = 0.002) groups. Conclusions: Persistent insomnia significantly increases the rate in which depression occurs over time in non-depressed individuals, which ultimately leads to higher risk for depression. Additionally, having persistent insomnia also increased the risk of suicidal ideation. Citation: Suh S; Kim H; Yang HC; Cho ER; Lee SK; Shin C.

The purpose of this study was to investigate the effects of pelvic floor muscle exercise using electric stimulation and biofeedback on maximum pressure of vaginal contraction, vaginal contraction duration and sexual function in women who have had vaginal rejuvenation. The research design was a non-equivalent control group non-synchronized design study. Participants in this study were women who had vaginal rejuvenation at C obstetrics and gynecology hospital. The 15 participants in the experimental group were given pelvic floor muscle exercise using electric stimulation and biofeedback and the 15 participants in the control group received self pelvic floor muscle exercise. For maximum pressure of vaginal contraction, the experimental group showed a statistically significant increase compared to than the control group (t=5.96, p<.001). For vaginal contraction duration, the experimental group also showed a statistically significant increase compared to the control group (t=3.23, p=.003). For women's sexual function, the experimental group showed a significant increase when compared to the control group in total sexual function scores (t=3.41, p=.002). The results indicate that pelvic floor muscle exercise with electric stimulation and biofeedback after vaginal rejuvenation is effective in strengthening vaginal contraction pressure, vaginal contraction and that it also positively functions to increase women's sexual function.

This study aims to evaluate the metabolic profile of non-obese children with OSAS. Fifty-two children were enrolled in this study, 21 girls and 31 boys. Patients were divided into two groups: OSAS (28 children) and Snore (22 children) according to polysomnographic evaluation. All children were submitted to ENT examination, measurements of weight, height and blood pressure. Blood samples were tested for hemoglobin, hematocrit, fasting glucose, fasting insulin, triglycerides, total cholesterol, HDL, LDL, VLDL, TSH and T4. The gathered data sets were compared between groups and also within the OSAS group according to the severity of the syndrome. The children from both groups had no alterations in blood pressure levels. The results of the blood tests were normal for both groups. Results of hemoglobin, hematocrit, and HDL were all significantly higher in the Snore group when compared to the OSAS group; by their turn, VLDL levels were higher in the OSAS group. There was no statistical difference between the groups based on OSAS severity. Non-obese children with OSAS present no significant alterations in metabolic tests or blood pressure levels.

BACKGROUND: Abdominal surgery can lead to postoperative intra-abdominal adhesions (PIAAs) with significant morbidity and mortality. This study compares the use of honey with a standard bioresorbable membrane (Seprafilm™) to prevent the formation of PIAAs in rats. METHODS: Thirty rats underwent laparotomy, and PIAAs were induced by scraping the cecum. The animals were divided into three groups, each containing ten rats. Group 1 (control) represented the cecal abrasion group, with no intraperitoneal administration of any substance. Group 2 (honey group) underwent cecal abrasion and intraperitoneal administration of honey. Group 3 (Seprafilm™ group) underwent cecal abrasion and intraperitoneal Seprafilm™ application. RESULTS: Group 1 exhibited higher adhesion scores for adhesions between the abdominal wall and the organs. Groups 2 and 3 had decreased adhesive attachments to the intra-abdominal structures. Compared to group 1, the incidence of adhesion formation was lower in both group 2 (p=0.001) and group 3 (p=0.001). The incidence of fibrosis was also lower in group 2 (p=0.016) and group 3 (p=0.063) compared to group 1. There was no significant difference between the histopathological fibrosis scores for the rats in group 2 and those in group 3 (p= 0.688). CONCLUSION: This study suggests that both honey and Seprafilm™ decrease the incidence of PIAAs in the rat cecal abrasion model. Although the mechanism of action is not clear, intraperitoneal administration of honey reduced PIAAs. The outcome of this study demonstrates that honey is as effective as Seprafilm™ in preventing PIAAs. PMID:19488596

This study evaluated the effectiveness of a health promotion (HP) intervention program among physiotherapy undergraduate students in an academic institution by examining pre- and post-intervention health perceptions and behaviors compared to a control group (non-physiotherapy students). Participants completed questionnaires on their health perceptions and behaviors at T1 (April 2009–May 2009) before the intervention program was initiated, and at T2 (April 2015–May 2015) after the intervention program was implemented for several years. At T1, 1,087 undergraduate students, including 124 physiotherapy students, participated. At T2, 810 undergraduate students, including 133 physiotherapy students participated. Self-reported health-related perceptions and behaviors were compared in the study group (physiotherapy students) over time (T1 versus T2), and between the study group and the control group (non-physiotherapy students) pre-intervention (T1) and post-intervention (T2). Findings showed more positive perceptions and behaviors at T2 compared to T1 in the study group (51.0% at T2 versus 35.2% at T1; p<0.05). There was no significant difference at T2 compared to T1 in health perceptions reported by the control group (37.8% at T2 versus 32.8% at T1; non-significant difference). Our findings demonstrated the effectiveness of the intervention program. PMID:28735335

This study was designed to compare the analgesic effects of cryoanalgesia and parecoxib in lung cancer patients after lobectomy. A total of 178 lung cancer patients awaiting large-sized lobectomy were enrolled in the study. The patients were randomly divided into Group A (intercostal nerve cryoanalgesia) and Group B (parecoxib). The analgesic and adverse effects were compared between the two groups. The pain score of Group A was significantly lower than that of Group B (P < 0.05). The patients in Group A used significantly less morphine than those in Group B (P < 0.05). There were also significantly fewer complications in Group A than in Group B (P < 0.05). Cryoanalgesia of the intercostal nerves can be considered an economical, safe and simple technique for the long-term management of post-lobectomy pain.

The risk for cardiovascular diseases and type 2 diabetes mellitus significantly increases in the patient population with metabolic syndrome (MeS). The present study aimed to investigate the association between the epicardial adipose tissue thickness (EATT) and the oxidative stress parameters in MeS patients. The study included 181 patients as a patient group of 92 consecutive patients with MeS and a control group of 89 consecutive patients with similar age and gender. EATT was evaluated by transthoracic echocardiography. Serum levels of total oxidant status (TOS), total antioxidative capacity (TAS), paraoxonase-1 (PON-1), and arylesterase activities were measured. EATT was higher in the MeS group compared to the control group (6.0 ± 2.0 mm and 4.0 ± 1.0 mm, resp.; P < 0.001). The level of TOS was higher in the MeS group compared to the control group (P < 0.001). Additionally, the TAS level was higher in the MeS group compared to the control group (P < 0.001). Furthermore, the serum levels of PON-1 and arylesterase were lower in the MeS group compared to the control group (P < 0.001). EAT may cause an increased risk of cardiovascular diseases by leading to increased oxidative stress in patients with MeS. PMID:25530760

Designing an intervention to increase physical activity is important to be based on the health care settings resources and be acceptable by the subject group. This study was designed to assess and compare the effect of the goal setting strategy with a group education method on increasing the physical activity of mothers of children aged 1 to 5. Mothers who had at least one child of 1-5 years were randomized into two groups. The effect of 1) goal-setting strategy and 2) group education method on increasing physical activity was assessed and compared 1 month and 3 months after the intervention. Also, the weight, height, body mass index (BMI), waist and hip circumference, and well-being were compared between the two groups before and after the intervention. Physical activity level increased significantly after the intervention in the goal-setting group and it was significantly different between the two groups after intervention (P < 0.05). BMI, waist circumference, hip circumference, and well-being score were significantly different in the goal-setting group after the intervention. In the group education method, only the well-being score improved significantly (P < 0.05). Our study presented the effects of using the goal-setting strategy to boost physical activity, improving the state of well-being and decreasing BMI, waist, and hip circumference.

This study investigates motor skill performance and self-perceived competence in children with anxiety disorders compared with children without psychiatric disorders. Motor skills and self-perception were assessed in 329 children aged 8 to 11 years, from the Bergen Child Study. The Kiddie-SADS PL diagnostic interview was employed to define a group of children with an anxiety disorder without comorbid diagnosis, and a control group (no diagnosis) matched according to gender, age, and full-scale IQ. Children in the anxiety disorder group displayed impaired motor skills and poor self-perceived peer acceptance and physical competence compared with the control group. Two-thirds of the anxious boys scored on the Motor Assessment Battery for Children (MABC) as having motor problems. The present study demonstrated impaired motor skills in boys with "pure" anxiety disorders. Anxious children also perceived themselves as being less accepted by peers and less competent in physical activities compared with children in the control group.

Group housing is considered to be important for rats, which are highly sociable animals. Single housing may impact behaviour and levels of circulating stress hormones. Rats are typically used in the toxicological evaluation of insulin analogues. Human insulin (HI) is frequently used as a reference compound in these studies, and a comparator model of persistent exposure by HI infusion from external pumps has recently been developed to support toxicological evaluation of long-acting insulin analogues. However, this model requires single housing of the animals. Developing an insulin-infusion model which allows group housing would therefore greatly improve animal welfare. The aim of the present study was to investigate the suitability of implantable infusion pumps for HI infusion in group-housed rats. Group housing of rats implanted with a battery-driven pump proved to be possible. Intravenous infusion of HI lowered blood glucose levels persistently for two weeks, providing a comparator model for use in two-week repeated-dose toxicity studies with new long-acting insulin analogues, which allows group housing, and thereby increasing animal welfare compared with an external infusion model.

Dysfunction of adhesion molecules is believed to play an early and important role in developing cancer. Accordingly, this study aims to compare beta-catenin (β-catenin) and CD44 expression in oral lichen planus (OLP) as a condition with malignant potential and oral squamous cell carcinoma (OSCC). β-Catenin and CD44 expression were evaluated in 15 patients with epithelial hyperplasia (group A), 20 OLP (group B), and 20 OSCC (group C) by immunohistochemistry. Quantitative and semi-quantitative evaluations revealed β-catenin, and CD44 membranous expression had significant differences among the three groups. Expression of these markers in the OSCC group decreased significantly compared to that of the OLP. Also, nuclear/cytoplasmic expression of β-catenin was significantly different among the three groups, considering that nuclear expression was not observed in any of the epithelial hyperplasia and OLP samples. According to the findings of this study, β-catenin and CD44 can differentiate between behavior of OLP and OSCC, while the precancerous nature of OLP and malignant transformation potential of it are not suggested. © 2018 The International Society of Dermatology.

Is the use of harmonic scalpel for neck dissection useful? Literature search did not show a single, prospective, randomised control trial. We intended to study the role of harmonic scalpel in neck dissection and compare it with conventional electrocautery technique for oral cavity carcinoma. 40 patients undergoing selective neck dissection for primary oral cavity malignancy were enrolled in this study. The harmonic scalpel (HS) group consisted of 20 patients, and the electrocautery technique (ET) group comprised of 20 patients. The following variables were examined: intraoperative blood loss, operative time, number of ligatures used, postoperative drain, and postoperative hospital stay. Intraoperative blood loss was found to be significantly reduced in harmonic scalpel group as compared to electrocautery group. However, we found no difference in other parameters like operative time, postop drain, postoperative hospital stay and number of ligatures used between both groups. Harmonic scalpel for neck dissection is associated with significantly lesser intraoperative blood loss as compared to electrocautery. There is no effect on operative time and postoperative hospital stay in both groups. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Colorectal cancer (CRC) is a common malignancy. There is growing evidence that CRC incidence is increasing in the younger population. There is controversy surrounding the prognosis of young patients with CRC. In this study we reviewed Australian patients with metastatic CRC (mCRC) who were younger than 40 years of age at the time of diagnosis of metastatic disease. To our knowledge this is the first study to focus on this age group with mCRC. This was a retrospective study using data from the South Australian Metastatic Colorectal Cancer database. We compared patient and disease characteristics, management approaches, and outcomes for age groups < 40 and ≥ 40. A multivariate Cox proportional hazards model was fitted to compare the survival outcomes (death from all causes) between the 2 groups. From 3318 patients, 46 (1.4%) were younger than 40 years of age. In a comparison of patients in the younger than 40-year-old group with the older group, a greater proportion had synchronous metastatic disease (80.4% vs. 64.4%, respectively; P = .04) and disease originating from the left colon (71.7% vs. 61.7%, respectively; P = .035); also a larger proportion in the younger than 40-year-old group received chemotherapy compared with the older group (82.6% vs. 58.7%, respectively; P < .01). In the adjusted multivariate model, survival was not significantly different between the 2 groups (hazard ratio, 0.81; 95% confidence interval, 0.56-1.16; log rank P = .25). Young-onset mCRC patients, when defined as aged younger than 40 years, have equivalent survival compared with their older counterparts. This is despite differences in disease characteristics and management approach between the 2 groups. Copyright © 2016 Elsevier Inc. All rights reserved.

The prevalence of sickle cell trait is extremely high in sub-Saharan Africa. Recent studies have reported the impact of sickle cell carriers on renal function. However, data on renal abnormalities in children with sickle cell trait in this part of the world are unknown. In this report, we assess the glomerular function of children with sickle cell trait (SCT). A case control study was conducted to assess the glomerular function in 43 Congolese children with sickle cell trait (Hb-AS) matched for age to 65 children with sickle cell anemia in steady state (Hb-SS) and 67 normal controls (Hb-AA). There was a significant difference in the blood pressure levels between the Hb-AS group vs Hb-SS group (P<.05). The estimated glomerular filtration rate (eGFR) corrected for body surface area was increased in Hb-AS group compared to Hb-AA group, but there was no significant difference between the two groups (P=.48). At the same time, the eGFR was decreased, but no significantly so, in the Hb-AS group compared to the Hb-SS group (P=.19). The proportion of children with Hb-AS (16.3%) who had hyperfiltration was higher compared to the proportion (6.1%) found in the Hb-AA group, but lower compared to the proportion found in the Hb-SS group (30%). However, in both situations, the difference was not statistically significant. No case of proteinuria was detected in children with Hb-AS. It appears that at least one of six children with SCT had hyperfiltration. The findings could form a basis for further studies on this renal physiology among SCT individuals in Africa. © 2017 Wiley Periodicals, Inc.

Low socio-economic group patients from rural areas often opt for free cataract surgeries offered by charitable organisations. SICS continues to be a time tested technique for cataract removal in such patients. In recent times, camp patients are sometimes treated by clear corneal phacoemulsification with implantation of a rigid IOL, which being more cost effective is often provided for camp patients. This study was undertaken to find out which surgical technique yielded better outcomes and was more suited for high volume camp surgery. To find the better surgical option- phacoemulsification with rigid IOL or SICS, in poor patients from rural areas. A prospective randomised controlled trial of cataract patients operated by two different techniques. One hundred and twelve eyes were selected and were randomly allocated into two groups of 56 eyes each. At completion of the study, data was analysed for 52 eyes operated by clear corneal phacoemulsification and implantation of a rigid IOL, and 56 eyes operated by SICS. Unpaired t-test was used to calculate the p- value. The results were evaluated on the following criteria. The mean post-operative astigmatism at the end of four weeks - was significantly higher in phacoemulsification group as compared to SICS group The BCVA (best corrected visual acuity) at the end of four weeks - was comparable in both groups. Subjective complaints and/ or complications: In phaco group two patients required sutures and seven had striate keratitis , while none in SICS group. Complaint of irritation was similar in both groups. Surgical time- was less for SICS group as compared to phaco group. SICS by virtue of being a faster surgery with more secure wound and significantly less astigmatism is a better option in camp patients from rural areas as compared to phacoemulsification with rigid IOL.

The aim of this systematic review was to apply the anatomic ACL reconstruction scoring checklist (AARSC) and to evaluate the degree to which clinical studies comparing single-bundle (SB) and double-bundle (DB) ACL reconstructions are anatomic. A systematic electronic search was performed using the databases PubMed (MEDLINE), EMBASE and Cochrane Library. Studies published from January 1995 to January 2014 comparing SB and DB ACL reconstructions with clinical outcome measurements were included. The items from the AARSC were recorded for both the SB and DB groups in each study. Eight-thousand nine-hundred and ninety-four studies were analysed, 77 were included. Randomized clinical trials (29; 38%) and prospective comparative studies (29; 38%) were the most frequent study type. Most studies were published in 2011 (19; 25%). The most commonly reported items for both SB and DB groups were as follows: graft type (152; 99%), femoral and tibial fixation method (149; 97% respectively), knee flexion angle during graft tensioning (124; 8%) and placement of the tibial tunnel at the ACL insertion site (101; 66%). The highest level of documentation used for ACL tunnel position for both groups was often one dimensional, e.g. drawing, operative notes or o'clock reference. The DB reconstruction was in general more thoroughly reported. The means for the AARSC were 6.9 ± 2.8 for the SB group and 8.3 ± 2.8 for the DB group. Both means were below a proposed required minimum score of 10 for anatomic ACL reconstruction. There was substantial underreporting of surgical data for both the SB and DB groups in clinical studies. This underreporting creates difficulties when analysing, comparing and pooling results of scientific studies on this subject.

During past decades, a connection between hepatitis and the host ABO/Rh blood groups has been always under dispute, with no appropriately designed study yet. This study aimed to investigate possible association between ABO blood/Rh groups with both hepatitis B and C. In this case-control setting, 200 healthy individuals (controls), 200 patients with chronic Hepatitis-B infection (HB) and 200 patients with chronic Hepatitis-C infection (HC) were recruited from 2010 to 2013 in Tabriz Sina Hospital. ABO blood and Rh grouping was performed and the results were compared between the case and control groups. Both pair of the control and HB groups and the control and HC groups were matched for their subjects' age and sex. In the control group, 178 subjects (89%) were Rh+ and 22 subjects (11%) were Rh-. In the HB group, there were 180 Rh+ (90%) and 20 Rh- (10%) patients. In the HC group there were 168 Rh+ (84%) and 32 Rh-negative (16%) patients. Both pair of the control and HB groups (p = 0.74), as well as the control and HC groups (p = 0.14) were comparable for the status of Rh. In the control group there were 84 (42%), 32 (16%), 66 (33%) and 18 (9%) subjects with A, B, O and AB blood groups, respectively. The corresponding figures were 84 (42%), 34 (17%), 58 (29%) and 24 (12%) for the HB patients; and 80 (40%), 29 (14.5%), 85 (42.5%) and 6 (3%) for the HC patients. Comparing between the control and HB groups showed no significant difference in terms of the frequency of ABO blood groups (p = 0.70). However, with comparing the control and HC groups, the rate of O blood group was significantly higher in the HC group and concomitantly, the rate of AB blood group was significantly higher in the control group (p = 0.04). Although, there is not a significant association between ABO blood groups and HB, this association is significant between certain ABO blood groups and HC.

To examine the caries status of pregnant women in southeast Hungary and compare the results with a similar study completed in the same region ten years earlier to determine whether any improvement has taken place in the past decade. Another objective was to assess the effects of age, socioeconomic status and number of pregnancies on oral health. The dental examination of 130 pregnant women was carried out at the Dental Clinic of University of Szeged, Faculty of Dentistry in 2011-2013 (group 1). Caries status was examined according to WHO guidelines. In order to compare demographic and socioeconomic factors with DMF indices, find the decisive influencing factors and compare the results with the results of the previous study (group 2), two-way ANOVA and regression analyses were conducted. The number of highly educated, professional, urban participants included in the present group (group 1) was greater compared with that of group 2. Despite the higher age of the pregnant women in present study, statistically significantly lower DMFT (10.05 vs 12.57, p = 0.008) and DMFS (19.41 vs 26.26, p = 0.001) scores were found than ten years ago. In both studies, the regression analyses showed that women's age was the main contributing factor to caries status. The lower DMFT and DMFS values and the participants' willingness to participate in the dental screening in the present study group were probably the result of their higher educational background and that they worked as professionals.

A meta-analysis regarding bone loss after bariatric surgery, designed to compare surgical and nonsurgical groups, has not yet been performed. Therefore, we performed a meta-analysis to compare the differences between bariatric surgical groups and nonoperated controls with regard to bone mineral density. In March 2015, we performed a review of the literature using PubMed, EMBASE, and the Cochrane Library. The search focused on retrospective and prospective studies, including but not limited to randomized studies published in English. Among 1299 studies that were initially screened, ten met the selection criteria. For all types of bariatric surgery, bone density at the femoral neck was lower in the surgical group than in the nonsurgical control group (mean difference [MD] -0.05 g/cm(2); 95 % confidence interval [CI], -0.07 to -0.02; p = 0.001); no difference in bone density was found between the two groups at the lumbar spine (MD -0.01 g/cm(2); 95 % CI -0.07 to 0.05; p = 0.661). The analysis of Roux-en-Y gastric bypass showed similar results. Bone density at the femoral neck decreased after bariatric surgery, compared to that in nonsurgical controls, whereas bone density at the lumbar spine did not show a difference between groups. Further larger scale studies with comparative nonsurgical controls are warranted to overcome the heterogeneity among studies in this analysis and to add evidence of possible bone loss subsequent to bariatric surgical procedures.

Previous studies have shown that dextromethorphan (DM), a N-methyl-D-aspartate (NMDA) receptor antagonist, produces a preemptive analgesic effect on post-operative pain. The aim of this study was to further examine the preemptive analgesic effect of intramuscular (i.m.) DM injection on unilateral total knee replacement (TKR). Sixty-four ASA I-III patients scheduled for unilateral TKR surgery were randomly allocated into three groups in a prospective double-blind manner. All patients received epidural anesthesia without any premedication. An initial bolus dose of 2% lidocaine (15-20 mL) followed by a maintenance dose of 8-10 mL/h was decided. Fentanyl (1.5 micrograms/kg) and diazepam (2 mg) were given i.v. before epidural catheter insertion. The epidural catheter was placed via the L2-L3 or L3-L4 interspace and advanced for 5 cm cephalad [corrected]. Patients received i.m. injection of 20 mg chlorpheniramine (CPM) before surgery as control (group C, n = 22). For the study groups, patients were given an i.m. injection containing 40 mg DM and 20 mg CPM, before (group B, n = 22) or after surgery (group A, n = 20), respectively. Postoperation, patients received intravenous morphine by means of a patient controlled analgesia (PCA) device for pain relief. The time to the first pull of PCA trigger, morphine consumption, worse pain scores (resting and incidental), and analgesics related side effects were recorded at 1, 2, 4, 8, 24, 48 and 72 h after surgery. The time from the end of operation to the first PCA trigger were 31.2 +/- 5.2 min in group C, 67.3 +/- 11.1 min in group B (P < 0.05, compared with group C) and 61.8 +/- 7.2 min in group A (P < 0.05, compared with group C) respectively. The relevant pain score at resting, observed at the 8 h postoperatively was respectively 4.2 +/- 0.1 in group C, 3.7 +/- 0.2 in group B (P < 0.05, compared with group C) and 3.4 +/- 0.2 in group A (P < 0.05, compared with group C); and at the 24 h was 3.1 +/- 0.2 in group C, 2.4 +/- 0.2 in group B (P < 0.05, compared with group C) and 2.5 +/- 0.1 in group A (P < 0.05, compared with group C) respectively. There were no significant differences in actual morphine delivery and frequency of PCA triggering at all time among the three groups. Moreover, there was also no significant statistic difference in morphine-associated side effects among the three groups. In the present study, we failed to observe any preemptive analgesic effect of DM (40 mg, i.m.) on postoperative pain in patients who received TKR under epidural anesthesia, however, DM given either before or after surgery augmented other analgesic (morphine) to offer a better pain relief.

OBJECTIVE Pain control is an important clinical consideration and quality-of-care metric. No studies have examined postoperative pain control following transsphenoidal surgery for pituitary lesions. The study goals were to 1) report postoperative pain scores following transsphenoidal surgery, 2) determine if multimodal opioid-minimizing pain regimens yielded satisfactory postoperative pain control, and 3) determine if intravenous (IV) ibuprofen improved postoperative pain scores and reduced opioid use compared with placebo. METHODS This study was a single-center, randomized, double-blinded, placebo-controlled intervention trial involving adult patients with planned transsphenoidal surgery for pituitary tumors randomized into 2 groups. Group 1 patients were treated with scheduled IV ibuprofen, scheduled oral acetaminophen, and rescue opioids. Group 2 patients were treated with IV placebo, scheduled oral acetaminophen, and rescue opioids. The primary end point was patient pain scores (visual analog scale [VAS], rated 0-10) for 48 hours after surgery. The secondary end point was opioid use as estimated by oral morphine equivalents (OMEs). RESULTS Of 136 patients screened, 62 were enrolled (28 in Group 1, 34 in Group 2). The study was terminated early because the primary and secondary end points were reached. Baseline characteristics between groups were well matched except for age (Group 1, 59.3 ± 14.4 years; Group 2, 49.8 ± 16.2 years; p = 0.02). Mean VAS pain scores were significantly different, with a 43% reduction in Group 1 (1.7 ± 2.2) compared with Group 2 (3.0 ± 2.8; p < 0.0001). Opioid use was significantly different, with a 58% reduction in Group 1 (26.3 ± 28.7 mg OME) compared with Group 2 (62.5 ± 63.8 mg OME; p < 0.0001). CONCLUSIONS Multimodal opioid-minimizing pain-management protocols resulted in acceptable pain control following transsphenoidal surgery. IV ibuprofen resulted in significantly improved pain scores and significantly decreased opioid use compared with placebo. Postoperative multimodal pain management, including a nonsteroidal antiinflammatory medication, should be considered after surgery to improve patient comfort and to limit opioid use.

Betapol consists of triglyceride fatty acids commonly found in vegetable and animal fats. A similarity to human milk fat indicated a potential use in infant formulae as well as for food use in general. To test the potential for substantial equivalence with a related food grade oil, palm oil, Betapol was fed to rats at 15% content in the diet using an augmented two-generation study, in order to obtain information on general (6 months), reproductive and postnatal developmental toxicity in a single study rather than separate studies. For comparison there were two control groups, namely a comparative control fed a diet containing 15% of food grade oil and a negative, or laboratory standard control fed a commercial rodent breeding diet (LAD), containing 2.3-4.7% fat. It was reasoned that if Betapol fed groups showed differences from the comparative control in the direction of the negative control these would reflect differences in the nutritional value of the high fat diets. Presence of a toxicant might be indicated by differences from the comparative control group opposite to the negative control group. The group fed 15% Betapol showed occasional, statistically significant differences from the comparative control group but the direction of difference was towards the negative control group and did not indicate the presence of an unexpected toxicant.

Background Very little is known about possible association of nevi and melasma. The study objective was to determine if there is an association between melasma and existence of different kinds of nevi. Methods In a case-control study, 120 female melasma patients referred to dermatology clinic of Ardabil and 120 patients referred to other specialty clinics who lacked melasma were enrolled after matching for age. Number of different types of nevi including lentigines and melanocytic nevi were compared between case and control group patients. Data were entered into the computer and analyzed by SPSS 13 statistical software. Results Mean number of lentigines was 25.5 in melasma group compared to 8 in control group(P < 0.01). Mean number of melanocytic nevi was 13.2 in cases compared to 2.8 in control group(P < 0.001). Multivariate analysis showed that existence of freckles, lentigines and more than three melanocytic nevi were positively related to developing melasma. The chance of melasma increased up to 23 times for patients having more than three melanocytic nevi. Congenital nevi were observed among 10% both in case and control groups. Campbell de morgan angiomas were seen among 26 patients(21.8%) in case group compared to 6 patients(5%) in control group. Conclusion Existence of lentigines and melanocytic nevi increases chance of having melasma PMID:18680608

The aim of the present study was to evaluate the efficiency of different endodontic irrigants in the removal of smear layer through scanning electron microscopic image analysis. The present in vitro study was carried out on 45 single-rooted extracted human mandibular premolar teeth with single canal and complete root formation. Teeth were randomly assigned to three groups with 15 teeth in each group. Group I samples were irrigated with 17% ethylenediaminetetraacetic (EDTA) irrigation, Group II with 7% maleic acid irrigation, and Group III with 2% chlorhexidine irrigation. Scanning electron microscope evaluation was done for the assessment of smear layer removal in the coronal, middle, and apical thirds. Comparison of the smear layer removal between the three different groups was done by Kruskal-Wallis test, followed by Mann-Whitney U test for comparing individual groups. A P value less than 0.05 was considered to be statistically significant. Statistically significant difference was seen between the two test groups (17% EDTA vs. 7% maleic acid and 17% EDTA vs. 2% chlorhexidine) in smear layer removal at coronal, middle, and apical thirds of the root canal. The most efficient smear layer removal was seen in Group I with 17% EDTA irrigation compared with other groups (P < 0.05) and the least by 2% chlorhexidine. The present study shows that 17% EDTA efficiently removes the smear layer from root canal walls.

Folic acid deficiency is a risk factor for schizophrenia through epidemiology, biochemistry and gene-related studies. Compared with healthy people, schizophrenic patients may have high homocysteine plasma values and homocysteine or low levels of folic acid, which seems to correlate with extrapyramidal motor symptoms caused by neuroleptic therapy and with symptoms of schizophrenia. In this present study, we focus on the difference of folic acid level between schizophrenic patient and control group. The study sample consisted of schizophrenic patients and 14 people in the control group and performed blood sampling to obtain the results of folic acid levels. The folic acid level in both groups was within normal range, but the schizophrenic patient group had lower mean folic acid values of 5.00 ng/ml (sb 1.66), compared with the control group with mean folic acid values of 10.75 ng/ml (sb 4.33). there was the group of the control group had a higher value of folic acid than the schizophrenic group.

In this study, we aimed to investigate whether the symptoms of vertigo related to hypertension resulted from endolymphatic hydrops and the efficacy of the thiazides in the treatment. A total of 24 vertigo patients without peripheric or central vestibular pathologies or hyperlipidemia were included. The study group comprised 15 patients with hypertension, including nine with regulated non-insulin-dependent diabetes mellitus (DM). The control group comprised nine patients without hypertension or DM. The patients in the study group received hydrochlorothiazide treatment. The European Evaluation of Vertigo Scale (EEVS) and Vertigo Handicap Questionnaire (VHQ), puretone audiometry, tympanometry, electronystagmography (ENG) for nystagmus tests, oculomotor tests, and caloric test were carried out initially and at three weeks for both groups. The results of the study group were compared to those of the control group. There was a statistically significant decrease in the scores of EEVS and VHQ at three weeks in the study group, compared to the baseline scores (for both groups p≤0.01). Our study results showed that thiazides alleviated vertigo symptoms in hypertensive patients, as measured by qualitative methods (i.e. EEVS, VHQ), but not with quantitative measurements (i.e. ENG).

Patients with intracranial tumour are usually on anticonvulsants. Patients on phenytoin therapy demonstrate rapid metabolism of nondepolarising muscle relaxants secondary to enzyme induction. Infusion dose requirement of rocuronium in such patients has been sparingly studied. We studied the continuous infusion dose requirement of rocuronium bromide in patients on phenytoin therapy and its correlation with serum levels of phenytoin. Seventy-five patients scheduled for supratentorial tumour surgery were included in the study. Patients not on phenytoin were taken as control. The primary outcome variable studied was the infusion dose requirement of rocuronium in patients on phenytoin. Based on pre-operative serum phenytoin levels, study group patients were divided into two groups: sub-therapeutic level group (phenytoin level <10 μg/mL) and therapeutic level group (phenytoin level >10 μg/mL). Following anaesthesia induction, rocuronium bromide 0.6 mg/kg was administered to achieve tracheal intubation. Rocuronium infusion was titrated to maintain zero response on the train-of-four response. Demographic data were comparable. Patients receiving phenytoin required higher infusion dose compared to the control group (0.429 ± 0.2 mg/kg/h vs. 0.265 ± 0.15 mg/kg/h, P < 0.001). The serum phenytoin level had no correlation to infusion dose requirement of rocuronium (0.429 ± 0.205 mg/kg/h vs. 0.429 ± 0.265 mg/kg/h ( P = 0.815). The recovery was faster in the phenytoin group compared to the control group. Haowever, it was not clinically significant. The infusion dose requirement of rocuronium bromide in patients on phenytoin is higher and the serum levels of phenytoin does not influence the dose required.

Introduction Dynamic cueing is an effective way of stimulating perception of regions of interest within radiological images. This study explores the impact of a novel teaching tool using dynamic cueing for lesion detection on plain chest radiographs. Materials and methods Observer performance studies were carried out where 36 novices examined 30 chest images in random order. Half of these contained between one and three simulated pulmonary nodules. Three groups were investigated: A (control: no teaching tool), B (retested immediately after undergoing the teaching tool) and C (retested a week after undergoing the teaching tool). The teaching tool involved dynamically displaying the same images with and without lesions. Results were compared using Receiver Operating Characteristics (ROC), sensitivity and specificity analyses. Results The second reading showed significantly greater area under the ROC curve (Az value) (p<0.0001) and higher sensitivity value (p=0.004) compared to the first reading for Group B. No differences between readings were demonstrated for groups A or C. When the magnitudes of the above changes were compared between Group B and the other two groups, greater changes in Az value for Group B were noted (B vs. A:p=0.0003, B vs. C:p=0.0005). For sensitivity, when Group B was compared to Group A, the magnitude of the change was significantly greater (p=0.0029) whereas when Group B was compared to Group C, the magnitude change demonstrated a level approaching significance (p=0.0768). Conclusions The novel teaching tool improves identification of pulmonary nodular lesions on chest radiographs in the short term.

To compare the outcome of pars-plana-modified Ahmed glaucoma valve (AGV) versus limbal-based conventional AGV into the anterior chamber, in patients undergoing penetrating keratoplasty (PK) for glaucoma with coexisting corneal diseases. In this prospective randomized clinical trial, 58 eyes of 58 patients with glaucoma and coexisting corneal disease were divided into two groups. Group 1 (29 eyes of 29 patients) included patients undergoing limbal-based conventional AGV into the anterior chamber (AC) along-with PK and group 2 (29 eyes of 29 patients) included those undergoing pars-plana-modified AGV along-with PK. Outcome measures included corneal graft clarity, intraocular pressure (IOP), number of antiglaucoma medications, and postoperative complications. Patients were followed up for a minimum period of 2 years. Out of 58 eyes (58 patients), 50 eyes (50 patients: 25 eyes of 25 patients each in group 1 and group 2) completed the study and were analyzed. Complete success rate for AGV (group 1: 76%; group 2: 72%; p = 0.842) and corneal graft clarity (group 1: 68%; group 2: 76%; p = 0.081) were comparable between the two groups at 2 years. Graft failure was more in conventional AGV (32%) as compared to pars plana-modified AGV (24%) but not statistically significant (p = 0.078) at 2 years. Though both procedures were comparable in various outcome measures, pars-plana-modified AGV is a viable option for patients undergoing PK, as it provides a relatively better corneal graft survival rate and lesser complications that were associated with conventional AGV.

To investigate the characteristics of residual symptoms and to evaluate the effects of adjuvant vestibular suppressants on residual symptoms after successful canalith repositioning procedures (CRPs). Individual randomized controlled trial. One hundred fifty patients with idiopathic benign paroxysmal positional vertigo who achieved successful CRPs on initial visit participated in this study. Dizziness Handicap Inventory (DHI) questionnaires were completed before CRPs. All study populations were divided into three groups after successful CRPs on the initial visit day: the medication (V) group (treated with a vestibular suppressant [dimenhydrinate 50 mg per day]), the placebo (P) group, and the no medication (N) group. One week after successful CRPs, residual symptoms were checked and repeated DHI questionnaires were completed to compare residual symptoms. Among the 138 patients who did not show positional nystagmus at follow-up, 67 (48.5%) complained of residual symptoms. The presence of residual symptoms was more prevalent in the P and N group compared with the V group (P = .035, P = .017, respectively). The most frequent residual symptom was lightheadedness (n = 42). Moreover, in the V group, lightheadedness was significantly reduced compared with the P group (P = .029). However, in the analysis of DHI, total and subscale scores did not differ across the three groups before or after successful CRP. Vestibular suppressants significantly reduced residual symptoms compared to both placebo and no medication after CRP. However, there was no significant reduction in DHI score compared with the control group, suggesting that the residual symptoms could not be evaluated by DHI score alone. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

Video-guided laryngoscopy, though unproven in achieving better success rates of laryngoscopy outcome and intubation, seems to provide better glottic visualization compared with direct laryngoscopy. The objective of this study was to compare the efficacy of video-guided laryngoscope (VGL) in the airway management skills of medical students. Medical students throughout their anesthesiology rotations were enrolled in this study. All students received standard training in the airway management during their course and were randomly allocated into two 20 person groups. In Group D, airway management was performed by direct laryngoscopy via Macintosh blade and in Group G intubation was performed via VGL. Time to intubation, number of laryngoscopy attempts and success rate were noted. Successful intubation was considered as the primary outcome. All data were analyzed using SPSS 16 software. Chi-square and Fisher's exact test were used for analysis of categorical variables. For analyzing continuous variables independent t-test was used. P < 0.05 was considered as statistically significant. Number of laryngoscopy attempts was less in Group G in comparison to Group D; this, however, was statistically insignificant (P: 0.18). Time to intubation was significantly less in Group G as compared to Group D (P: 0.02). Successful intubation in Group G was less frequently when compared to Group D (P: 0.66). Need for attending intervention, esophageal intubation and hypoxemic events during laryngoscopy were less in Group G; this, however, was statistically insignificant. The use of video-guided laryngoscopy improved the first attempt success rate, time to intubation, laryngoscopy attempts and airway management ability of medical students compared to direct laryngoscopy.

Dexamethasone, a known immunosuppressant, can inhibit the immune response and increase the amount of pathogen in body, but the role of dexamethasone affecting susceptibility of crucian carp (Carassius auratus) to pathogen is unclear. The effects of dexamethasone on susceptibility of crucian carp to Aeromonas hydrophila were investigated in this study. The fish were divided into four groups randomly and injected intraperitoneally by dexamethasone for 0 day (group D), 3 days (group C), 6 days (group B), and 9 days (group A), respectively. The serum lysozyme activity was significantly declined in group A, B and C. Relative immune gene expression such as il-1β, cxcl-8, tnfα and crp in kidney were down-regulation compared to group D. After that crucian carp were infected with A. hydrophila, crucian carp treated by dexamethasone had higher mortality (group A 95%, group B 76%, group C 31%) when compared to group D (4% mortality); the amount of pathogen in was significantly increased (P < 0.05) in liver, kidney and spleen of fish in group A-C compared to group D. These results implicated that higher susceptibility caused by dexamethasone may be induced by the decrease of lysozyme activity and the down-regulation of some immune genes.

We conducted a study to determine whether dutasteride reduces the risk of incident prostate cancer, as detected on biopsy, among men who are at increased risk for the disease. In this 4-year, multicenter, randomized, double-blind, placebo-controlled, parallel-group study, we compared dutasteride, at a dose of 0.5 mg daily, with placebo. Men were eligible for inclusion in the study if they were 50 to 75 years of age, had a prostate-specific antigen (PSA) level of 2.5 to 10.0 ng per milliliter, and had had one negative prostate biopsy (6 to 12 cores) within 6 months before enrollment. Subjects underwent a 10-core transrectal ultrasound-guided biopsy at 2 and 4 years. Among 6729 men who underwent a biopsy or prostate surgery, cancer was detected in 659 of the 3305 men in the dutasteride group, as compared with 858 of the 3424 men in the placebo group, representing a relative risk reduction with dutasteride of 22.8% (95% confidence interval, 15.2 to 29.8) over the 4-year study period (P<0.001). Overall, in years 1 through 4, among the 6706 men who underwent a needle biopsy, there were 220 tumors with a Gleason score of 7 to 10 among 3299 men in the dutasteride group and 233 among 3407 men in the placebo group (P=0.81). During years 3 and 4, there were 12 tumors with a Gleason score of 8 to 10 in the dutasteride group, as compared with only 1 in the placebo group (P=0.003). Dutasteride therapy, as compared with placebo, resulted in a reduction in the rate of acute urinary retention (1.6% vs. 6.7%, a 77.3% relative reduction). The incidence of adverse events was similar to that in studies of dutasteride therapy for benign prostatic hyperplasia, except that in our study, as compared with previous studies, the relative incidence of the composite category of cardiac failure was higher in the dutasteride group than in the placebo group (0.7% [30 men] vs. 0.4% [16 men], P=0.03). Over the course of the 4-year study period, dutasteride reduced the risk of incident prostate cancer detected on biopsy and improved the outcomes related to benign prostatic hyperplasia.

In France, the number of cannabis users has doubled over the last ten years. The groups most affected are 18-25 year old adults in higher education. This study involved 300 persons currently undergoing core health education training (79 teachers, 135 nurses and 86 social workers). As health educators in training, they were subject to the completion of an adapted version of the EROPP survey (Exploring the Representations, Opinions and Perceptions of Psychotropic Drugs). Results were compared with those of a French survey of the general population undertaken in 2002. Differences between the study and the control groups, and between the different types of students, were analysed using the Chi-square test. Cannabis users were also compared with non-users. The results show an over-consumption of cannabis in the study group compared to the general population, especially in men, both in terms of experimentation and current use. The specificities of each group are analysed and the results discussed in light of the study group's potential role in health education.

Diabetes mellitus is a global disease that is increasing in an alarming rate. The present study was undertaken to study the antidiabetic effect of the ethanol extracts of Carica papaya and Pandanus amaryfollius on streptozotocin-induced diabetic mice. The results of the present study indicated that there was no significant difference in the body weight of the treated groups when compared to diabetic control. Whereas, there was significant (P < 0.05) decrease in the blood glucose level of the plant-treated groups compared to the diabetic control. Histologically the pancreas of the treated groups indicated significant regeneration of the β-cells when compared to the diabetic control. The liver tissues of the treated group indicated a reduction in fatty changes and pyknotic nucleus. The kidney tissues of the treated groups indicated significant recovery in the cuboidal tissue. The results from the phytochemical screening indicated the presence of flavonoids, alkaloids, saponin and tannin in C. papaya and P. amaryfollius. The antidiabetic effect of C. papaya and P. amaryfollius observed in the present study may be due to the presence of these phytochemicals.

To investigate whether using a parametric statistic in comparing groups leads to different conclusions when using summative scores from rating scales compared with using their corresponding Rasch-based measures. A Monte Carlo simulation study was designed to examine between-group differences in the change scores derived from summative scores from rating scales, and those derived from their corresponding Rasch-based measures, using 1-way analysis of variance. The degree of inconsistency between the 2 scoring approaches (i.e. summative and Rasch-based) was examined, using varying sample sizes, scale difficulties and person ability conditions. This simulation study revealed scaling artefacts that could arise from using summative scores rather than Rasch-based measures for determining the changes between groups. The group differences in the change scores were statistically significant for summative scores under all test conditions and sample size scenarios. However, none of the group differences in the change scores were significant when using the corresponding Rasch-based measures. This study raises questions about the validity of the inference on group differences of summative score changes in parametric analyses. Moreover, it provides a rationale for the use of Rasch-based measures, which can allow valid parametric analyses of rating scale data.

A prospective, randomized, clinical study with a 2-year follow-up. To analyze the effect of three different rehabilitation strategies for lumbar spinal fusion patients. Fifteen percent to 40% of lumbar spinal fusion patients are not expected to improve significantly over a 2-year period. Optimization of present forms of rehabilitation could possibly further improve the outcome. Between 1996 and 1999, 90 patients who had undergone lumbar spinal fusion were 3 months after surgery randomized to one of three different rehabilitation groups. Video group participants watched a video of exercises for training and were subsequently and only once provided instruction regarding their use. The back-café group was provided the same program as the video group, but as a supplement met with a back-café with other fusion-operated patients three times over an 8-week period. The training group was provided physical therapy training twice weekly for 8 weeks. Functional outcome was evaluated at 6, 12, and 24 months after surgery by use of the low back pain rating scale and a questionnaire covering daily functions, work status, and a patient's contact with the primary sector. By 2-year follow-up, the back-café and video groups had less pain compared with the training group (P < 0.03). The back-café group was better at performing daily functions such as carrying bags of market items (P < 0.01), getting up from a chair (P < 0.01), and ascending staircases (P < 0.01) compared with the video and training groups. More in the back-café group resumed working after surgery compared with the two other groups (P < 0.04). The video group had significantly more contacts with general practitioners, physical therapists, and so on compared with the back-café and training groups (P < 0.001). The patients in the back-café group were significantly better at accomplishing a succession of daily tasks compared with the video and training groups 2 years after lumbar spinal fusion. At the 2-year follow-up the training group had a significant pain problem compared with the video and back-café groups. The video group had significantly more treatment demands outside the hospital system. This study demonstrates the relevance of the inclusion of coping schemes and questions the role of intensive exercises in a rehabilitation program for spinal fusion patients.

Tramadol was found to be more effective than dexamethasone in post-operative pain control, with long-lasting relief of pain. This study aimed to compare the effects of pre-operative local injections of tramadol and dexamethasone on post-operative pain, nausea and vomiting in patients who underwent tonsillectomy. Sixty patients between 3-13 years of age who were planned for tonsillectomy were included in the study. Patients were divided into three groups. Group 1 was the control group. Patients in Group 2 received 0.3 mg/kg Dexamethasone and Group 3 received 0.1 mg/kg Tramadol injection to the peritonsillary space just before the operation. Patients were evaluated for nausea, vomiting, and pain. When the control and the dexamethasone groups were compared; there were statistically significant differences in pain scores at post-operative 15 and 30 min, whereas there was no statistically significant difference in pain scores at other hours. When the control and tramadol groups were compared, there was a statistically significant difference in pain scores at all intervals. When tramadol and dexamethasone groups were compared, there was no statistically significant difference in pain scores at post-operative 15 and 30 min, 1 and 2 h, whereas there was a statistically significant difference in pain scores at post-operative 6 and 24 h.

Males have higher incidence of hepatocellular carcinoma (HCC) than females. Sex hormones may be a risk factor. The aim was to determine the levels of sex hormones in male and female patients with HCC and cirrhosis versus controls and its possible relationship with HCC. This study was conducted on 90 subjects divided into 40 patients with HCC, 30 patients with liver cirrhosis and 20 apparently healthy subjects complete blood picture, liver function tests. Determination of AFP levels and hormonal assay of oestrogen, progesterone, total testosterone, prolactin, FSH and LH were performed on all subjects. Total testosterone levels were significantly decreased in the two patients groups compared with controls. While oestrogen levels were significantly decreased in the HCC group in comparison with other two groups, prolactin levels were significantly decreased in the HCC group compared with the liver cirrhosis group and increased in the liver cirrhosis group when compared to controls. FSH and LH levels were significantly increased in the HCC group when compared to controls. There is no significant correlation between sex hormones assay and both the size of HCC and degree of cirrhosis in both patient groups. It is concluded that there is no strong relation between sex hormones and HCC when the study was carried out on the levels of sex hormones in patients with HCC. © 2016 Blackwell Verlag GmbH.

Parenteral nutrition (PN) covering the need for carbohydrates, amino acids, and lipids can either be compounded from single nutrients or purchased as an industrially manufactured ready-to-use regimen. This study compares a commercially available 3-chamber bag (study group) with a conventionally compounded monobag regarding nutrition efficacy, safety, and regimen preparation time. This prospective, randomized, single-blind study was conducted at 5 Chinese hospitals from October 2010-October 2011. Postsurgical patients requiring PN for at least 6 days were randomly assigned to receive the study or control regimen. Plasma concentrations of prealbumin and C-reactive protein (CRP), regimen preparation time, length of hospital stay (LOS), 30-day mortality, safety laboratory parameters, and adverse events (AEs) were recorded. In total, 240 patients (121 vs 119 in study and control groups) participated in this study. Changes in prealbumin concentrations during nutrition support (Δ Prealb(StudyGroup) = 2.65 mg/dL, P < .001 vs Δ Prealb(ControlGroup) = 0.27 mg/dL, P = .606) and CRP values were comparable. Regimen preparation time was significantly reduced in the study group by the use of 3-chamber bags (t (StudyGroup) = 4.90 ± 4.41 minutes vs t (ControlGroup) = 12.13 ± 5.62 minutes, P < .001). No differences were detected for LOS, 30-day mortality, safety laboratory parameters, and postoperative AEs (37 vs 38 in study and control groups). The PN regimen provided by the 3-chamber bag was comparable to the compounded regimen and safe in use. Time savings during regimen preparation indicates that use of 3-chamber bags simplifies the process of regimen preparation.

Context: Invasion of the bifurcation and trifurcation of the multi-rooted teeth resulting in furcation involvement is one of the serious complications of periodontitis. Aim: The purpose of the study was to evaluate the efficacy of combination therapy using anorganic bovine bone graft and resorbable guided tissue regeneration (GTR) membrane versus open flap debridement alone in the management of Grade II furcation defects in mandibular molars. Materials and Methods: The study included a total number of 20 sites in 10 patients with bilateral mandibular furcation defects, out of which 10 sites were treated as test group and 10 as control group. The test group was treated with combination therapy and the control group with open flap debridement alone. The parameters were recorded on 0 day (baseline), 90th day, and 180th day, which included vertical probing depth and horizontal probing depth of the furcation defect, clinical attachment level, and defect fill. Statistical Analysis Used: Mean and standard deviation were calculated for different variables in each study group at different time points. Mean values were compared by using Wilcoxon signed ranks test, after adjusting the P values for multiple comparison by using Bonferroni correction method. Results: Both the test and control groups showed a definitive improvement in clinical parameters, which was statistically significant. On comparison, the vertical probing depth showed significant reduction in the test group with a mean reduction of 3.1 ± 0.7 mm, when compared to the control group which showed a mean reduction of 1.5 ± 0.5 mm. The horizontal probing depth of furcation defects was also significantly reduced in the test group with a mean reduction of 2.2 ± 0.6 mm, when compared to the control group in which the mean reduction was 0.9 ± 0.3 mm. There was also significant gain in attachment level in the test group which showed a mean gain of 3.2 ± 0.6 mm, when compared to the control group which showed a gain of 1.2 ± 0.6 mm. Radiographic defect fill was found to be more in the test group with a mean gain of 2.0 ± 0.1 mm, when compared to the control group which showed a defect fill of 0.2 ± 0.1 mm. Conclusions: The results of this study demonstrated that the combined use of anorganic bovine bone graft and resorbable GTR membrane is effective than open flap debridement alone in the treatment of mandibular grade II furcation defects.

Experimental studies and clinical trials designed to help patients recover from various brain injuries, such as stroke or trauma, have been attempted. Rehabilitation has shown reliable, positive clinical outcome in patients with various brain injuries. Transplantation of exogenous neural stem cells (NSCs) to repair the injured brain is a potential tool to help patient recovery. This study aimed to evaluate the therapeutic efficacy of a combination therapy consisting of rehabilitation and NSC transplantation compared to using only one modality. A model of motor cortex resection in rats was used to create brain injury in order to obtain consistent and prolonged functional deficits. The therapeutic results were evaluated using three methods during an 8-week period with a behavioral test, motor-evoked potential (MEP) measurement, and measurement of the degree of endogenous NSC production. All three treatment groups showed the effects of treatment in the behavioral test, although the NSC transplantation alone group (CN) exhibited slightly worse results than the rehabilitation alone group (CR) or the combination therapy group (CNR). The latency on MEP was shortened to a similar extent in all three groups compared to the untreated group (CO). However, the enhancement of endogenous NSC proliferation was dramatically reduced in the CN group compared not only to the CR and CNR groups but also to the CO group. The CR and CNR groups seemed to prolong the duration of endogenous NSC proliferation compared to the untreated group. A combination of rehabilitation and NSC transplantation appears to induce treatment outcomes that are similar to rehabilitation alone. Further studies are needed to evaluate the electrophysiological outcome of recovery and the possible effect of prolonging endogenous NSC proliferation in response to NSC transplantation and rehabilitation.

Severe dorsal deviations in crooked noses are treated by either in situ septoplasty with asymmetric spreader grafts (ISS) or extracorporeal subtotal septal reconstruction (ECS). To our knowledge, except one retrospective study, there is no other that compares the objective and subjective results of these two treatment modalities. The aim of this study was to compare the aesthetic and functional outcomes of ECS and ISS in crooked noses. This study was carried out on 40 patients (ISS in 20 patients and ECS in 20 patients) who underwent external rhinoplasty surgery due to crooked noses between May 2014 and January 2016. While performing rhinoplasty on the patients, the decision of whether to use the ECS or ISS technique was randomized in a sequential fashion. Surgical outcomes were assessed and compared using the anthropometric measurement of photographs with Rhinobase software. Subjective assessments of nasal obstruction and aesthetic satisfaction were evaluated with a visual analog scale. There was a significant difference between rhinion deviation angle, supratip deviation angle (SDA) and tip deviation angle pre- and postoperatively in the ECS group, whereas in the ISS group, except SDA, all other postoperative angles were significantly improved from preoperative values (p = 0.218). The nasal tip projection in the ECS and ISS groups was 29.48, 31.5 preoperatively and 29.78, 31.26 postoperatively. The mean postoperative nasal tip projection value (p > 0.005) did not change significantly compared to the preoperative value in both groups. The mean postoperative value of nasolabial (p = 0.226) angle did not change significantly compared to the mean preoperative one in the ECS group. However, in the ISS group, the mean postoperative value of nasolabial (p = 0.001) angle significantly improved compared to the mean preoperative value. There was significant improvement in both groups, while improvements in both functional and aesthetic outcomes were much higher in the extracorporeal group. None of the patients had postoperative nasal obstruction that required revision surgery. One patient underwent revision rhinoplasty due to an irregularity on the nasal dorsum in the ECS group. This is the first study that compares subjective and objective aesthetic and functional outcomes of crooked nose surgery according to two common septoplasty techniques in a randomized self-controlled fashion. This study was effective in both objectively and subjectively comparing the functional and aesthetic aspect of the patients submitted to two common different techniques of treatment of nasal deviations in crooked nose patients.

The purpose of this study was investigating the effects of curcumin on the histological changes and functional recovery following spinal cord injury (SCI) in a rat model. Following either sham operation or SCI, 36 male Sprague-Dawley rats were distributed into three groups: sham group, curcumin-treated group, and vehicle-injected group. Locomotor function was assessed according to the Basso, Beattie, and Bresnahan (BBB) scale in rats who had received daily intraperitoneal injections of 200 mg/kg curcumin or an equivalent volume of vehicle for 7 days following SCI. The injured spinal cord was then examined histologically, including quantification of cavitation. BBB scores were significantly higher in rats receiving curcumin than receiving vehicle (P < 0.05). The cavity volume was significantly reduced in the curcumin group as compared to the control group (P = 0.039). Superoxide dismutase (SOD) activity was significantly elevated in the curcumin group as compared to the vehicle group but was not significantly different from the sham group (P < 0.05, P > 0.05, respectively) at one and two weeks after SCI. Malondialdehyde (MDA) levels were significantly elevated in the vehicle group as compared to the sham group (P < 0.05 at 1 and 2 weeks). MDA activity was significantly reduced in the curcumin group at 2 weeks after SCI when compared to the vehicle group (P = 0.004). The numbers of macrophage were significantly decreased in the curcumin group (P = 0.001). This study demonstrated that curcumin enhances early functional recovery after SCI by diminishing cavitation volume, anti-inflammatory reactions, and antioxidant activity.

Proper positioning of the head and neck is important for an optimal laryngeal visualization. Traditionally, sniffing position (SP) is recommended to provide a superior glottic visualization, during direct laryngoscopy, enhancing the ease of intubation. Various studies in the last decade of this belief have challenged the need for sniffing position during intubation. We conducted a prospective study comparing the sniffing head position with simple head extension to study the laryngoscopic view and intubation difficulty during direct laryngoscopy. Five-hundred patients were included in this study and randomly distributed to SP or simple head extension. In the sniffing group, an incompressible head ring was placed under the head to raise its height by 7 cm from the neutral plane followed by maximal extension of the head. In the simple extension group, no headrest was placed under the head; however, maximal head extension was given at the time of laryngoscopy. Various factors as ability to mask ventilate, laryngoscopic visualization, intubation difficulty, and posture of the anesthesiologist during laryngoscopy and tracheal intubation were noted. In the incidence of difficult laryngoscopy (Cormack Grade III and IV), Intubation Difficulty Scale (IDS score) was compared between the two groups. There was no significant difference between two groups in Cormack grades. The IDS score differed significantly between sniffing group and simple extension group ( P = 0.000) with an increased difficulty during intubation in the simple head extension. Patients with simple head extension needed more lifting force, increased use of external laryngeal manipulation, and an increased use of alternate techniques during intubation when compared to SP. We conclude that compared to the simple head extension position, the SP should be used as a standard head position for intubation attempts under general anesthesia.

Relationships among pest flour beetles of the genus Tribolium (Tenebrionidae) inferred from multiple molecular markers

Model species often provide initial hypotheses and tools for studies of development, genetics, and molecular evolution in closely related species. Flour beetles of the genus Tribolium MacLeay (1825) are one group with potential for such comparative studies. Tribolium castaneum (Herbst 1797) is an increasingly useful developmental genetic system. The convenience with which congeneric and other species of tenebrionid flour beetles can be reared in the laboratory makes this group attractive for comparative studies on a small phylogenetic scale. Here we present the results of phylogenetic analyses of relationships among the major pest species of Tribolium based on two mitochondrial and three nuclear markers (cytochrome oxidase 1, 16S ribosomal DNA, wingless, 28S ribosomal DNA, histone H3). The utility of partitioning the dataset in a manner informed by biological structure and function is demonstrated by comparing various partitioning strategies. In parsimony and partitioned Bayesian analyses of the combined dataset, the castaneum and confusum species groups are supported as monophyletic and as each other’s closest relatives. However, a sister group relationship between this clade and Tribolium brevicornis (Leconte 1859) is not supported. Therefore, we suggest transferring brevicornis group species to the genus Aphanotus Leconte (1862). The inferred phylogeny provides an evolutionary framework for comparative studies using flour beetles. PMID:18024090

To investigate the effects of intravenous infliximab in preventing the formation of peritoneal adhesions in an animal model of rat. This was an experimental study being performed in animal laboratory of Shiraz University of Medical Sciences during 2012. Sixty albino rats were randomly assigned in to three groups by Random Design Method. The first group received single infliximab injection (n=20), the second one received double infliximab injection (n=20) and the third received nothing (n=20), after receiving intra-peritoneal injection of talc for induction of peritoneal adhesions. All the animals were sacrificed after 6 weeks and the peritoneal adhesions were evaluated according to Nair classification. We observed that the mean adhesion grade was lower in those who received double dose of infliximib when compared to single dose and controls. However the difference did not reach a significant value (p=0.178). The grade of peritoneal adhesion was also comparable between the three study groups (p=0.103). The mean number of 1st WBC count was also comparable between three study groups (p=0.382). We observed that 2nd WBC count was also comparable between two study groups (p=0.317). Administration of intravenous infliximab after intraabdominal surgicalprocedures would not prevent the formation of peritoneal adhesions in animal model of albino rat.

The aim of the study was to analyse the early and long-term outcomes of a consecutive series of patients who underwent sequential coronary artery bypass grafting (CABG) and to compare them with a matched population of totally arterial revascularized patients. From January 1994 to December 1996, 209 patients underwent total arterial myocardial revascularization at our institution [arterial (ART) group]. In the same period, 2097 patients underwent CABG with left internal thoracic artery on left anterior descending and great saphenous vein on the right and circumflex branches sequentially [sequential vein (SV) group]. The propensity score methodology was used to obtain risk-adjusted outcome comparisons between the two groups (209 vs 243 patients in the ART group and SV group, respectively). In-hospital mortality was 1% in the ART group and 0.4% in the SV group (P = 0.86). Mean follow-up was 14 ± 4 years. Long-term survival was comparable among the two study groups [actuarial 5- and 15-year survival rates were 97 vs 93% and 82 vs 79% in the ART group and the SV group, respectively (P = 0.29)]. At follow-up, recurrence of angina (17 vs 18%; P = 0.99), acute myocardial infarction (MI) (3 vs 5%; P = 0.72) and repeated percutaneous coronary intervention (19 vs 21%; P = 0.69) were similar in the ART group compared with the SV group. In the Cox regression analysis, type of revascularization was not an independent predictor of any long-term outcomes (death or major adverse cardiac events). In asymptomatic patients, exercise stress test at follow-up was comparable between the two groups (P = 0.14). Sequential vein CABG appears to have good early and long-term clinical outcomes. Also, early and long-term incidence of acute MI was not significantly higher in the SV group. However, further studies with a larger population are warranted in order to confirm the present results. © The Author 2014.

Background: Myopia is very common ophthalmic disease especially in children and adolescence. In Ayurvedic texts, only by the main feature impairment of distant vision myopia can be correlated with Drishtigata Rogas (2nd Patalgata Timira). Aim: To compare the effect of Saptamruta Lauha and Yoga therapy in myopia. Materials and Methods: In present study, a total 60 patients with age group between 8 to 30 years were selected randomly from the out-patient Department of Swasthavritta and Shalakyatantra Department of Government Ayurveda College, Trivandrum, and were divided in two groups. In Group A, Saptamrita Lauha 250 mg twice daily with unequal quantity of honey and Ghrita was administered while in Group B, patients subjected to Yoga therapy (Jala Neti, Nadi Shodhana, Shitali Pranayama and point Tratak) for 3 months duration with 1 month follow-up. Results and Conclusion: The result obtained from the study reveals that there is no significant reduction in the visual acuity and clinical refraction, but associated changes were observed as reduced in group B when compared to group A. However, relief from headache was found to be equally effective in both the groups. PMID:25364195

Background: In this study, we attempt to identify the most appropriate catheter (silicone vs. latex) for short-term urinary catheterization. We compared the post-operative clinico-pathological complications between latex and silicone for short term catheterization in rabbits with hypospadias. Materials and Methods: Forty rabbits were used in our study to compare complications of catheterization. They were divided in two groups. Hypospadias like defect was created by a 1 cm long excision of the ventral urethra. For urethroplasty, we used tubularized incised plate technique. Latex and silicon catheters were used in groups 1 and 2, respectively. Post-operatively, routine laboratory urine test and complications (allergy, infection, bleeding) were compared in groups. Results: A total of 40 rabbits underwent hypospadias repair. Findings showed that there were no significant differences between groups based on urine test indices (P = NS). Urinary tract infection rate was 10% (2 rabbits) in latex and 0% in silicone groups (P = NS). There were no significant differences between groups regarding of cystitis grades between study groups (P = NS). Conclusion: It seems that urinary tract catheterization with latex catheters is a safe, feasible, and in-expensive procedure for short-term post-operative course in hypospadias surgery in patients without latex hypersensitivity.

The present study was planned to evaluate the safety and efficacy of vinyl bags in prevention of hypothermia during resuscitation at birth in very low birth weight neonates. Sixty neonates of gestational age ≤32 weeks and birth weight ≤ 1500gm were randomised to either study group, or control group. Study group neonates were put in vinyl bags up to neck and the head was covered with a cap after drying immediately following delivery and resuscitated under radiant warmer. Control group neonates were resuscitated by conventional drying under radiant warmer. Mean axillary and rectal temperature recorded immediately after admission to NICU were significantly higher in the study group compared to control group. Temperature recorded after 1 hour of admission to NICU were however comparable between the two groups. As temperature maintenance in these VLBW neonates is of tremendous importance, it would make sense to recommend the use of vinyl bags during their resuscitation.

The clinical effectiveness of a group-visit model versus individual point-of-care visits is compared by International Normalized Ratio (INR) monitoring in a pharmacist-managed anticoagulation clinic. This study was a prospective, randomized, repeated-measures, two-group, intention-to-treat comparison and survey at a pharmacist-managed anticoagulation clinic in a managed-care ambulatory care setting. Patients were eligible for this study if they were taking warfarin therapy for at least 30 days, had a goal INR range, and provided consent. At a routine point-of-care visit, eligible patients were randomly invited to participate in group visits. The number of visits and INR values were documented prospectively for both groups during the 16-week study period. Of the 45 patients who consented and enrolled in group visits, 28 patients participated for the 16-week study period. The control group included 108 patients seen by a pharmacist for individual anticoagulation appointments. No significant difference in the percentage of INR values within the therapeutic range was detected between patients in the group-visit model versus patients receiving individual visits (59% versus 56.6%, respectively; p = 0.536). Seventy-three percent of INR values for patients who attended group visits were within +/- 0.2 of the desired INR range compared with 71.9% of those in the control group ( p = 0.994). In addition, 79% of group-visit patients were within the therapeutic range at their last clinic visit compared with 67% of patients who attended individual appointments (p = 0.225). Group visits were preferred by 51% (n = 38) of patients who completed the satisfaction survey. Of the 92 patients who declined group-visit participation, 36% indicated that the time of day that group visits were offered was inconvenient. There were no thromboembolic or hemorrhagic events documented in either group during the study period. Group visits in a pharmacist-managed anticoagulation clinic may provide a safe and effective alternative to individual appointments.

The aim of this study was to investigate the effect of the use of nutrition labeling on nutritional intake according to age groups, focusing on Korean elderly. Study participants (N = 5223) were adults at least 20 y of age and had participated in the Korean National Health Examination and Nutrition Survey in 2012. Data for recognition/use of nutrition labels were obtained by self-report. Nutrition intake also was estimated by 24-h dietary recall. Participants were categorized into three age groups: 20 to 39 y, 40 to 59 y, and ≥60 y. Generalized linear model was conducted to test mean differences between nutrition label recognition (NLR) and nutrition label use (NLU) groups for nutrient intake, according to the age groups. Results from this study indicated that younger individuals (age groups of 20-39 and 40-59 y) in the NLU group showed a significant association with nutrient intake compared to those in the NLR group. Additionally, nutrition intake status in the NLU group improved positively. Whereas older participants (≥60 y) in the NLR group showed a significant association with most nutrient intake compared with the NLU group. The study also found that protein intake was reduced in the NLU group compared with the non-NLU group across the age groups, except for older participants (age group 20-39 y: 79.16 versus 86.30 g, P = 0.050; age group 40-59 y: 69.97 versus 75.58 g, P = 0.040; age group of ≥60 y: 64.72 versus 64.89 g, P = 0.967). The present study revealed that nutrition labeling cannot be effective for the elderly, and there were several areas of misunderstanding. Therefore, more systematic education on the topic of nutrition labeling is required to help the elderly make healthier food decisions. Copyright © 2016 Elsevier Inc. All rights reserved.

Abstract The aim of the present study was to compare differential impacts of bariatric surgery and exercise-induced weight loss on excessive abdominal and cardiac fat deposition. Excessive fat accumulation around the heart may play an important role in the pathogenesis of cardiovascular disease. Recent evidences have suggested that bariatric surgery results in relatively less decrease in epicardial fat compared with abdominal visceral fat and paracardial fat. Sixty-four consecutive overweight or obese subjects were enrolled in the study. Clinical characteristics and metabolic profiles were recorded. The volumes of abdominal visceral adipose tissue (AVAT), abdominal subcutaneous adipose tissue (ASAT), epicardial (EAT), and paracardial adipose tissue (PAT) were measured by computed tomography in the bariatric surgery group (N = 25) and the exercise group (N = 39) at baseline and 3 months after intervention. Subjects in both the surgery and exercise groups showed significant reduction in body mass index (15.97%, 7.47%), AVAT (40.52%, 15.24%), ASAT (31.40, 17.34%), PAT (34.40%, 12.05%), and PAT + EAT (22.31%, 17.72%) (all P < 0.001) after intervention compared with baseline. In both the groups, the decrease in EAT was small compared with the other compartments (P < 0.01 in both groups). Compared with the exercise group, the surgery group had greater loss in abdominal and cardiac visceral adipose tissue (AVAT, ASAT, PAT, EAT+PAT) (P < 0.001), but lesser loss in EAT (P = 0.037). Compared with the exercise group, bariatric surgery results in significantly greater percentage loss of excessive fat deposits except for EAT. EAT, but not PAT, was relatively preserved despite weight reduction in both the groups. The physiological impact of persistent EAT deserves further investigation. PMID:26844473

The aim of this study was to comparatively evaluate the vitreous depth (VD) of keratoconic eyes in patients with or without vernal keratoconjunctivitis (VKC). Eighty eyes of 80 consecutive keratoconus (KC) patients and 40 emmetropic control subjects were enrolled. KC patients were divided into two groups according to accompanying VKC (VKC-KC group and KC group). Mean outcome measures were best-corrected visual acuity (BCVA), spherical equivalent (SE), mean keratometry (Km), intraocular pressure (IOP), and axial length (AL) and its components. The eyes with the highest Km were selected for statistical analysis for each participant. There were 50, 30, and 40 patients in the VKC-KC group, KC group, and control group respectively. The KC group and VKC-KC group were similar in BCVA, SE, Km, CCT, ACD, LT, and IOP (p>0.05). The mean ACD was significantly lower in the control group when compared with the KC group and VKC-KC group. The mean AL and VD were significantly higher in VKC-KC group than those of KC group and the control group, whereas similar in KC and control groups (p>0.05). In the current study we showed that VKC-associated KC patients have significantly longer AL and VD when compared with KC patients without VKC. Posterior segment elongation in VKC-KC group may be associated with the type IV collagen destruction due to chronic longstanding inflammation in VKC patients.

The purpose of our study was to evaluate the safety and efficacy of transcervical amnioinfusion during labour complicated by meconium-stained amniotic fluid, in a setting with limited peripartum facilities, to lower the incidence of caesarean section. A prospective study was conducted in a teaching hospital in north India, which enrolled 292 patients admitted in labour. Patients were randomly divided into two groups after taking their consent. One group received transcervical amnioinfusion, whilst in the other group amnioinfusion was not done. Caesarean sections were performed in either group if there were foetal heart rate abnormalities (bradycardia or irregularity for 10-20 min) or slow progress of labour. The outcomes studied were the incidence of caesarean sections, duration of maternal hospital stay, maternal febrile morbidity (temperature of >38 degrees C, 24 h after delivery), low Apgar score (at 1 and 5 min), respiratory death, MAS and perinatal mortality. There was a statistically significant reduction in the incidence of caesarean sections in the study group compared to the control group (31 vs. 61%). Amnioinfusion was associated with improved neonatal outcome as evidenced by statistically improved Apgar score at 1 min in newborns in the study group compared to the control group (10 vs. 37.2%). Amnioinfusion during labour was not associated with any significant maternal and neonatal complications. The mean hospital stay of the mother was decreased significantly in the study group patients compared to the control group. Transcervical amnioinfusion in labour for meconium-stained amniotic fluid is a simple, safe and easy-to-perform procedure. It can be performed safely in a setup with limited peripartum facilities, especially in developing countries, to decrease intrapartum operative intervention and reduce foetomaternal morbidity and mortality.

One of the major advantages for patients undergoing minimally invasive surgery as compared to an open surgical procedure is the improved recovery profile and decreased opioid requirements in the perioperative period. There are no definitive studies comparing the analgesic requirements in patients undergoing two different types of minimally invasive procedure. This study retrospectively compares the perioperative analgesic requirements in severely obese adolescents and young adults undergoing laparoscopic versus robotic-assisted, laparoscopic gastric sleeve resection. With Institutional Review Board approval, the medication administration records of all severely obese patients who underwent gastric sleeve resection were retrospectively reviewed. Intra-operative analgesic and adjuvant medications administered, postoperative analgesic requirements, and visual analog pain scores were compared between those undergoing a laparoscopic procedure versus a robotic-assisted procedure. This study cohort included a total of 28 patients who underwent gastric sleeve resection surgery with 14 patients in the laparoscopic group and 14 patients in the robotic-assisted group. Intra-operative adjuvant administration of both intravenous acetaminophen and ketorolac was similar in both groups. Patients in the robotic-assisted group required significantly less opioid during the intra-operative period as compared to patients in the laparoscopic group (0.15 ± 0.08 mg/kg vs. 0.19 ± 0.06 mg/kg morphine, P = 0.024). Cumulative opioid requirements for the first 72 postoperative h were similar in both the groups (0.64 ± 0.25 vs. 0.68 ± 0.27 mg/kg morphine, P = NS). No difference was noted in the postoperative pain scores. Although intraoperative opioid administration was lower in the robotic-assisted group, the postoperative opioid requirements, and the postoperative pain scores were similar in both groups.

This study was performed to show long-term outcomes concerning globe preservation in uveal melanoma patients after proton beam therapy with the main focus on outcomes according to different adjuvant ab interno surgical procedures. Retrospective cohort study. All patients treated with primary proton beam therapy for choroidal or ciliary body melanoma between June 1998 and June 2015 were included. A total of 2499 patients underwent primary proton beam therapy, with local tumor control and globe preservation rates of 95.9% and 94.8% after 5 years, respectively. A total of 110 (4.4%) patients required secondary enucleation. Unresponsive neovascular glaucoma was the leading cause of secondary enucleation in 78 of the 2499 patients (3.1%). The 5-year enucleation-free survival rate was 94.8% in the endoresection group, 94.3% in the endodrainage group, and 93.5% in the comparator group. The log-rank test showed P = .014 (comparator group vs endoresection group) and P = .06 (comparator group vs endodrainage-vitrectomy group). Patients treated with endoresection or endodrainage-vitrectomy developed less radiation retinopathy (30.5% and 37.4% after 5 years, P = .001 and P = .048 [Kaplan-Meier], respectively) and less neovascular glaucoma (11.6% and 21.3% after 5 years, P = .001 and P = .01 [Kaplan-Meier], respectively) compared with the comparator group (52.3% radiation retinopathy and 57.8% neovascular glaucoma after 5 years). This study suggests that in larger tumors the enucleation and neovascular glaucoma rates might be reduced by adjuvant surgical procedures. Although endoresection is the most promising adjuvant treatment option, the endodrainage-vitrectomy is recommended in patients who are ineligible for endoresection. Copyright © 2017 Elsevier Inc.

Despite a long medical history of identification and treatment, hemorrhoids still pose a challenge to the medical fraternity in terms of finding satisfactory cure of the disease. In this study, Kshar Sutra Ligation (KSL), a modality of treatment described in Ayurveda, was compared with Barron's Rubber Band Ligation (RBL) for grade II and grade III hemorrhoids. This study was conducted in 20 adult patients of either sex with grade II and grade III hemorrhoids at two different hospitals. Patients were randomly allotted to two groups of 10 patients each. Group I patients underwent RBL, whereas patients of group II underwent KSL. Guggul-based Apamarga Kshar Sutra was prepared according to the principles laid down in ancient Ayurvedic texts and methodology standardized by IIIM, Jammu and CDRI, Lucknow. Comparative assessment of RBL and KSL was done according to 16 criteria. Although the two procedures were compared on 15 criteria, treatment outcome of grade II and grade III hemorrhoids was decided chiefly on the basis of patient satisfaction index (subjective criterion) and ability of each procedure to deal with prolapse of internal hemorrhoidal masses (objective criterion): Findings in each case were recorded over a follow-up of four weeks (postoperative days 1, 3, 7, 15 and 30). Statistical analysis was done using Student's t test for parametric data and Chi square test & Mann-Whitney test for non-parametric data. P < 0.05 was considered significant. RBL had the advantages of being an OPD procedure requiring no anesthesia and was attended by significantly lesser postoperative recumbency (P < 0.001 ) and significantly lesser pain (P < 0.005 on day 1) as compared to KSL. However, Group II (KSL) scored better in terms of treatment outcome. In Group II, there was significantly high (P < 0.05) patient satisfaction index as compared to Group I. Group II reported 100% 'cure' (absence of hemorrhoidal masses even on proctoscopy) of internal hemorrhoidal prolapse as against 80% in Group I (RBL); however, this difference was statistically insignificant (P > 0.05). Both the groups were comparable statistically on all other grounds. Kshar Sutra Ligation is a useful form of treatment for Grades II and III internal hemorrhoids. PMID:20814519

The aim of this study was to investigate the effect of inhalation of Salvia sclarea (clary sage; clary) or Lavandula angustifolia (lavender) essential oil vapors on autonomic nervous system activity in female patients with urinary incontinence undergoing urodynamic assessment. STUDY DESIGN, LOCATION, AND SUBJECTS: This study was a double-blind, randomized, controlled trial carried out in 34 female patients with urinary incontinence. The subjects were randomized to inhale lavender, clary, or almond (control) oil at concentrations of 5% (vol/vol) each. Systolic blood pressure, diastolic blood pressure, pulse rate, respiratory rate, and salivary cortisol were measured before and after inhalation of these odors for 60 minutes. The clary oil group experienced a significant decrease in systolic blood pressure compared with the control (p=0.048) and lavender oil (p=0.026) groups, a significant decrease in diastolic blood pressure compared with the lavender oil group (p=0.034) and a significant decrease in respiratory rate compared with the control group (p<0.001). In contrast, the lavender oil group tended to increase systolic and diastolic blood pressure compared with the control group. Compared with the control group, inhalation of lavender oil (p=0.045) and clary oil (p<0.001) resulted in statistically significant reductions in respiratory rate. These results suggest that lavender oil inhalation may be inappropriate in lowering stress during urodynamic examinations, despite its antistress effects, while clary oil inhalation may be useful in inducing relaxation in female urinary incontinence patients undergoing urodynamic assessments.

Body weight loss is an important feature of heart failure (HF) and tumors. It is related to both reduced survival and adverse reactions to therapy in both of these conditions. The mechanisms of body weight loss in patients with HF and tumors are considered to be similar. Yet, studies comparing those two populations are generally lacking. The aim of this study was to compare anthropometric and laboratory data, related to weight loss, between patients with chronic HF and patients with different tumors as well as control population. Laboratory and anthropometric data on 143 consecutive patients with chronic HF and malignant diseases as well as data for 20 controls were collected. Patients with HF had lower levels of C-reactive protein (CRP) and albumin compared to controls. Anthropometric measurements revealed lower body mass index (BMI), muscle strength, mid-arm circumference, and waist circumference in patients with HF compared to controls. Measurements of biceps, triceps, subscapular, and suprailiac skinfolds were also lower in HF group. Compared to solid tumor group, HF patients had lower levels of CRP and higher levels of hemoglobin. Solid tumor patients had lower values of BMI and subscapular skinfold thickness, as well as higher muscle strength compared to HF group. Finally, compared to patients with solid hematological tumors, HF group had lower levels of albumin, lower muscle strength, as well as lower mid-arm circumference. We found differences in anthropometric and laboratory features, related to weight loss, in patients with HF compared to control population that were expected. On the other hand, observed differences in HF group compared to patients with various tumors could imply different pathophysiological mechanisms of weight loss between those groups. Such data could serve as a cornerstone for studies with larger numbers of patients and deeper pathophysiological insight.

The objective of this study was to measure the efficacy of protection orders (POs) in reducing assault and injury-related outcomes using a matched comparison group and tracking outcomes over time. This study was a retrospective review of police, emergency department, family court, and prosecutor administrative records for a cohort of police-involved female IPV victims; all events over a 4-year study period were abstracted. Victims who obtained POs were compared with a propensity-score-based match group without POs over three time periods: Before, During, and After the issuance of a PO. Having a PO in place was associated with significantly more calls to police for nonassaultive incidents and more police charging requests that were of multiple-count and felony-level. Comparing outcomes, PO victims had police incident rates that were more than double the matched group prior to the PO but dropped to the level of the matched group during and after the order. ED visits dropped over time for both groups. This study confirmed the protective effect of POs, which are associated with reduced police incidents and emergency department visits both during and after the order and reduced police incidents compared with a matched comparison group.

This study aimed to compare and evaluate the changes in the salivary flow rate, pH, and buffering capacity before and after chewing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and xylitol-containing chewing gums in children. Sixty children aged between 8 and 12 years were selected for the study. They were randomly divided into Group 1 (CPP-ACP chewing gum) and Group 2 (xylitol-containing chewing gum) comprising thirty children each. Unstimulated and stimulated saliva samples at 15 and 30 min interval were collected from all children. All the saliva samples were estimated for salivary flow rate, pH, and buffering capacity. Significant increase in salivary flow rate, pH, and buffering capacity from baseline to immediately after spitting the chewing gum was found in both the study groups. No significant difference was found between the two study groups with respect to salivary flow rate and pH. Intergroup comparison indicated a significant increase in salivary buffer capacity in Group 1 when compared to Group 2. Chewing gums containing CPP-ACP and xylitol can significantly increase the physiochemical properties of saliva. These physiochemical properties of saliva have a definite relation with caries activity in children.

Introduction: Patients with threatened miscarriage associated with adverse pregnancy outcomes because of associated pregnancy and labor complications. Objectives: To evaluate the effect of threatened miscarriage on early and late pregnancy outcome. Methods: A retrospective case–controlled study was performed on 89 women with threatened miscarriage (study group) at Maternity and Children Hospital Buraidah, KSA from January 2010 to December 2010. They were matched for age and parity to 45 cases (control group) attending route antenatal clinic at the same time. Data recorded included, demographic characteristics and detailed pregnancy outcome and ultrasound finding including gestational age, cardiac activity and subchorionic hematoma. Results: The overall adverse pregnancy outcome was significantly higher in the studied cases compared to the control group (p=015).The miscarriage rate was significantly higher in study group compared to the controls group, (16.9%vs 2.2%, p=0000). Preterm delivery, babies with low birth weight and premature rupture of membranes were significantly higher in the miscarriage group compared to the controls group, (15.7% vs 2.2%, p=0.001), (15.7% vs 2.2%), p=0.001) and (6.7%) vs 4.45), p=0.016). There were no significant differences in other pregnancy outcomes. Conclusion: threatened miscarriage is associated with increased incidence of adverse pregnancy outcome. The risk is specially increased in premature rupture of the membranes, preterm delivery and neonatal birth weight. PMID:23678307

The aim of this study was to compare the incidence of postoperative complications, including superficial incisional surgical site infection (SSI) following purse-string skin closure (PS) and conventional skin closure with a drainage tube (CD) following stoma closure. A total of 55 consecutive patients who underwent loop colostomy and loop ileostomy closures in our hospital between October, 2011 and September, 2014 were retrospectively assessed. The patients were divided into two groups, namely the PS group (26 patients) and the CD group (29 patients). There were no significant differences in the characteristics of the patients between the two groups. The baseline and operative characteristics also did not differ significantly between the two groups. However the incidence of superficial incisional SSI was lower in the PS group compared to that in the CD group (0 vs. 13.8%, respectively; P=0.049). The overall incidence of complications did not differ significantly between the two groups (P=0.313). The duration of postoperative hospital stay in the PS group was shorter compared to that in the CD group. In conclusion, the results of this study suggest that PS may an effective technique to reduce the incidence of superficial incisional SSI. This technique appears to be superior to the conventional technique, allowing for better cosmesis. PMID:26137277

The purpose of this study was to determine the effect of the isolated vocal-facilitating techniques Chant Talk and Pitch Inflections on the phonation of healthy female speech-language pathology (SLP) students. A multigroup pretest-posttest design was used. A homogenous group of 40 healthy female SLP students with a mean age of 18.7 years were randomly assigned into 3 groups: a Chant Talk group (practicing Chant Talk across 18 weeks), a Pitch Inflections group (practicing Pitch Inflections across 18 weeks), and a control group (practicing no facilitating techniques). To compare vocal measures before and after this time span, an identical objective voice assessment protocol (aerodynamic measurement, acoustic analysis, voice range profile, and Dysphonia Severity Index) was performed in the 3 groups. Both Chant Talk and Pitch Inflections groups resulted in a significant decrease of the acoustic measure noise-to-harmonics ratio compared with the control group. The Chant Talk group resulted in a significant increase in the acoustic measure fundamental frequency compared with the control group. The results of this pilot study suggest that the facilitating techniques Chant Talk and Pitch Inflections may improve the objective measure of breathiness (noise-to-harmonics ratio) in healthy female SLP students.

To compare single versus 2-session laser photoablation for flat neovascularization in cases with Zone 1 aggressive posterior retinopathy of prematurity. Twenty-nine Asian Indian infants with aggressive posterior retinopathy of prematurity were randomized; each eye received 1 of 2 methods (29 each in Group A or B) proposed by the PHOTO-ROP group. Group A underwent single session laser to the avascular retina underlying the flat neovascularization by direct laser over the fronds. Group B underwent laser in 2 sessions; first, laser was delivered to the avascular periphery up to the flat neovascularization and 7 days later to the avascular bed exposed by the retraction of the fronds. Outcome and complications between the two groups were compared. Mean birthweight and gestational ages were 1,276 g and 30.1 weeks, respectively. All eyes showed favorable outcome at a minimum 12-month follow-up. Hemorrhages after laser (41.4% vs. 17.2%, P < 0.001) were more common in the single laser group. Large hemorrhages (>1 disk diameter) seen in Group A took longer than 8 weeks to resolve and developed focal fibrosis. This study demonstrates that the two-staged laser procedure produces fewer and smaller hemorrhages and no fibrosis compared with a single session. Both methods have comparable favorable outcomes in Asian Indian infants.

Fipronil is a widely used insecticide for termite control. Although transfer of fipronil among termite cohorts has been investigated in previous studies, no study has yet focused on the influence of termite group size (density) on horizontal transfer. In this study, the mortality of donor and recipient Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae) was compared among groups of 10, 25, and 50 workers. Most donor termites were dead within 20 h. There was a significantly higher mortality of recipient termites starting at 44 h when in bigger groups. LT50 and LT90 of recipient termites decreased with increase in group size, being significantly shorter in groups of 50 termites compared with groups of 10 termites. Moreover, the variance (within-group difference) of recipient mortality and lethal time estimations was lowest in the groups of 50 termites, indicating a more uniform horizontal transfer of fipronil by termites in bigger groups. Our findings suggest that group size has an influence on fipronil transfer among C. formosanus workers and should be considered as a variable of importance.

Insulin resistance and β-cell function are different between the young and elderly diabetes individuals, which are not well elaborated in the nondiabetic persons. The aims of this study were to compare insulin resistance and β-cell function between young and old adults from normal glucose tolerance (NGT) to prediabetes [which was subdivided into isolated impaired fasting glucose (i-IFG), isolated impaired glucose tolerance (i-IGT), and a combination of both (IFG/IGT)], and compare the prevalence of diabetes mellitus (DM) in the above prediabetes subgroups between different age groups after 3 years. A total of 1 374 subjects aged below 40 or above 60 years old with NGT or prediabetes were finally included in this study. Insulin resistance and β-cell function from homeostasis model assessment (HOMA) and interactive, 24-variable homeostatic model of assessment (iHOMA2) were compared between different age groups. The rate of transition to diabetes between different age groups in all pre-diabetes subgroups was also compared. Compared with the old groups, young i-IFG and IFG/IGT groups exhibit higher log HOMA-IR and log HOMA2-S, whereas the young i-IGT groups experienced comparable log HOMA-IR and log HOMA2-S when compared with old i-IFG and IFG/IGT groups. Three prediabetes subgroups all had similar log HOMA-B and log HOMA2-B between different age groups. In addition, the prevalence of diabetes in young i-IFG was statistically higher than that in old i-IFG after 3 years. Age is negatively related to log HOMA2-B in both age groups. Considering an age-related deterioration of β-cell function, young i-IFG, young i-IGT, and young IFG/IGT all suffered a greater impairment in insulin secretion than the old groups. Young i-IFG and IFG/IGT have more severe insulin resistance than the old groups. In addition, young i-IFG characterized with a higher incidence of DM than the old i-IFG. These disparities highlight that the prevention to slow progression from prediabetes to type 2 diabetes should be additionally focused in young prediabetes individuals, especially young i-IFG. © Georg Thieme Verlag KG Stuttgart · New York.

Tooth extraction is one of the most commonly performed procedures in dentistry. It is usually a traumatic procedure often resulting in immediate destruction and loss of alveolar bone and surrounding soft tissues. Various instruments have been described to perform atraumatic extractions which can prevent damage to the paradental structures. Recently developed physics forceps is one of the instruments which is claimed to perform atraumatic extractions. The aim of the present study was to compare the efficacy of physics forceps with conventional forceps in terms of operating time, prevention of marginal bone loss & soft tissue loss, postoperative pain and postoperative complications following bilateral premolar extractions for orthodontic purpose. In this prospective split-mouth study, outcomes of the 2 groups (n = 42 premolars) requiring extraction of premolars for orthodontic treatment purpose using Physics forceps and Conventional forceps were compared. Clinical outcomes in form of time taken, loss of buccal soft tissue and buccal cortical plate based on extraction defect classification system, postoperative pain and other complication associated with extraction were recorded and compared. Statistically significant reduction in the operating time was noted in physics forceps group. Marginal bone loss and soft tissue loss was also significantly lesser in physics forceps group when compared to conventional forceps group. However, there was no statistically significant difference in severity of postoperative pain between both groups. The results of the present study suggest that physics forceps was more efficient in reducing operating time and prevention of marginal bone loss & soft tissue loss when compared to conventional forceps in orthodontically indicated premolar extractions.

This study was undertaken to compare the clinical effectiveness and costs of postoperative splintage and late rehabilitation with a bulky bandage dressing versus early rehabilitation after carpal tunnel release. In this comparative study, 46 patients were randomly divided into 2 groups. In each group, 3 patients were excluded because of improper follow-up, leaving a total of 40 patients. Group 1 used a splint (exercises given 3 wk postoperatively) and group 2 was given a bulky bandage (exercises provided immediately) after open release. Patients were assessed preoperatively and at the first and third postoperative months with the Questionnaire of Levine for Clinical Assessment of Carpal Tunnel Syndrome. The 2 groups were similar in terms of preoperative functional status scores and in controls at the first and third months (P=.549, P=.326, P=.190). When both groups were compared, no statistical significance was found regarding symptom severity scale scores preoperatively and at the first postoperative month (P=.632 vs P=.353). At the third month, scores were lower in favor of group 2 (P=.023). Additionally, 16 of 20 patients (80%) in group 1 reported a heavy feeling and discomfort caused by the splint. This problem was not reported by the patients in group 2. The cheapest splint on the market was 9 times more expensive than a bulky dressing. The investigators concluded that postoperative immobilization with a splint has no detectable benefits. Use of bulky dressings and abandonment of the use of postoperative splints may prevent unnecessary expenditures without sacrificing patient comfort or compromising the course of healing in carpal tunnel surgery.

We characterized the probiotic properties of Lactobacillus helveticus strains KII13 and KHI1 isolated from fermented cow milk by in vitro and in vivo studies. The strains exhibited tolerance to simulated orogastrointestinal condition, adherence to Caco-2 cells, and antimicrobial activity. Both L. helveticus strains produced bioactive tripeptides, isoleucylprolyl-proline and valyl-prolyl-proline, during fermentation of milk. KII13 showed higher in vitro cholesterol-lowering activity (47%) compared with KHI1 (28%) and L. helveticus ATCC 15009 (22%), and hence, it was selected for in vivo study of cholesterol-lowering activity in atherogenic diet-fed hypercholesterolemic mice. For the study, mice were divided into four groups ( viz ., normal diet control group, atherogenic diet control group (HCD), KII13- atherogenic diet group (HCD-KII13), and Lactobacillus acidophilus ATCC 43121-atherogenic diet group (HCD- L.ac ) as positive control). The serum total cholesterol level was significantly decreased by 8.6% and 7.78% in the HCD-KII13 and HCD- L.ac groups ( p < 0.05), respectively, compared with the HCD group. Low-density lipoprotein cholesterol levels in both HCD-KII13 and HCD- L.ac groups were decreased by 13% and 11%, respectively, compared with the HCD group (both, p < 0.05). Analysis of cholesterol metabolism-related gene expression in mice liver showed increased expression of LDLR and SREBF2 genes in mice fed with KII13. By comparing all the results, we conclude that L. helveticus KII13 could be used as a potential probiotic strain to produce antihypertensive peptides and reduce serum cholesterol.

This prospective pilot study was undertaken to evaluate the feasibility and effectiveness of using a radiation absorbing shield to reduce operator dose from scatter during lower limb endovascular procedures. A commercially available bismuth shield system (RADPAD) was used. Sixty consecutive patients undergoing lower limb angioplasty were included. Thirty procedures were performed without the RADPAD (control group) and thirty with the RADPAD (study group). Two separate methods were used to measure dose to a single operator. Thermoluminescent dosimeter (TLD) badges were used to measure hand, eye, and unshielded body dose. A direct dosimeter with digital readout was also used to measure eye and unshielded body dose. To allow for variation between control and study groups, dose per unit time was calculated. TLD results demonstrated a significant reduction in median body dose per unit time for the study group compared with controls (p = 0.001), corresponding to a mean dose reduction rate of 65 %. Median eye and hand dose per unit time were also reduced in the study group compared with control group, however, this was not statistically significant (p = 0.081 for eye, p = 0.628 for hand). Direct dosimeter readings also showed statistically significant reduction in median unshielded body dose rate for the study group compared with controls (p = 0.037). Eye dose rate was reduced for the study group but this was not statistically significant (p = 0.142). Initial results are encouraging. Use of the shield resulted in a statistically significant reduction in unshielded dose to the operator's body. Measured dose to the eye and hand of operator were also reduced but did not reach statistical significance in this pilot study.

Ischemia-reperfusion (I/R) injury is one of the risk factors for delayed graft function, acute rejection episodes, and impaired long-term allograft survival after kidney transplantation. This antigen-independent inflammatory process produces tissue damage. Isogeneic transplantation in a rat model is a useful method for study of nonimmunologic risk factors for kidney damage. To study the effect of sirolimus on I/R injury using only 1 dose of the drug in the donor. Eighteen rats were allocated to 3 groups of 6 rats each: sham group, control group, and rapamycin group. Improved renal function and systemic inflammatory response were observed in the rapamycin group compared with the control group (Deltaurea, Deltacreatinine, and DeltaC3, all P < .01). The number of apoptotic nuclei in the renal medulla in the control group was higher than in the rapamycin group (P < .01). Tubular damage was less severe in the rapamycin group compared with the control group (P < .01). Complement 3 and tumor necrosis factor-alpha expression in the kidney samples were significantly decreased when rapamycin was given to the donor rats (P > .01). Bcl-2 protein was upregulated in the rapamycin group compared with the control group (P < .01). Administration of rapamycin in donors attenuates the I/R injury process after kidney transplantation in a rat model.

The aim of this study was to compare celecoxib with loxoprofen for protection of small intestine. RCT studies report that COX-2 selective inhibitor celecoxib induces fewer small intestinal injuries than nonselective nonsteroidal anti-inflammatory drugs (NSAIDs). Loxoprofen is a prodrug nonselective NSAID developed to protect upper gastrointestinal tract. A total of 150 healthy volunteers (40 to 70 y) were enrolled. After medical checkup including laboratory data, subjects were randomly assigned to celecoxib (200 mg daily) or loxoprofen (180 mg daily) plus lansoprazole (15 mg daily). All drugs were prepared using inactive capsules. After randomization, all subjects were first examined by baseline capsule endoscopy (CE). After 14 days, subjects underwent posttreatment CE. We compared baseline and posttreatment CE findings of the 2 groups. All CE data were evaluated blindly by 3 reviewers. Pretreatment and posttreatment laboratory variables were also compared. A total of 74 subjects (49±6 y, F/M: 36/38) were enrolled in celecoxib group and 76 subjects (49±7 y, F/M: 39/37)in loxoprofen group. Five in celecoxib group and 4 in loxoprofen group were excluded from CE analysis mainly due to incomplete CE. The percentage of subjects with at least 1 posttreatment mucosal break was lower in celecoxib group (10%) than in loxoprofen group (49%) (P<0.0001). A total of 0.3±1.0 posttreatment small intestinal mucosal breaks were detected in the celecoxib group, and 6.8±21.5 in the loxoprofen group (P<0.0001). Posttreatment hemoglobin concentration in loxoprofen group (5.1% reduction) was lower compared with celecoxib group (2.1% reduction) (P=0.006). In terms of protection of small intestine from NSAIDs toxicity, celecoxib monotherapy was superior to loxoprofen+lansoprazole combination therapy (UMIN: 000007936).

Objective Lead exposure in children can lead to neuropsychological impairment. This study tested whether primary prevention interventions in the newborn period prevent elevated blood lead levels (BLLs). Methods The Philadelphia Lead Safe Homes (LSH) Study offered parental education, home evaluation, and lead remediation to the families of urban newborns. Households were randomized to a standard lead education group or maintenance education group. We conducted home visits at baseline, six months, and 12 months. To compare BLLs, we identified a matched comparison group. Results We enrolled and randomized 314 newborns in the intervention component; 110 completed the study. There were few significant differences between the randomized groups. In the combined intervention groups, positive results on visual inspection declined from baseline to 12 months (97.0% to 90.6%, p=0.007). At baseline, 36.9% of homes were above the U.S. Environmental Protection Agency's lead dust standard, compared with 26.9% at 12 months (p=0.032), mainly due to a drop in windowsill dust levels. Both groups showed a significant increase in parental scores on a lead education test. Children in the intervention and matched control groups had similar geometric mean initial BLLs (2.6 vs. 2.7, p=0.477), but a significantly higher percentage of children in the intervention group had an initial blood lead screening compared with those in the matched group (88.9% vs. 84.4%, p=0.032). Conclusions A study of primary prevention of lead exposure showed a higher blood lead screening rate for the combined intervention groups and mean BLLs at one year of age not statistically different from the comparison group. Most homes had lead hazards. Lead education significantly increased knowledge. PMID:21563715

Background: Numerous cross-sectional studies have suggested that chronic periodontitis is a risk factor for cardiovascular diseases. There is evidence that periodontitis and cardiovascular diseases are linked by inflammatory factors including C-reactive protein. The purpose of the study was to investigate the levels of CRP and PNM cells as a marker of inflammatory host response in the serum of chronic periodontitis patients and in patients with CVD. Materials and Methods: Study population included 75 patients; both male and female above 35 years were included for the study. The patients were divided into three groups of 25 each – Group I: Chronic periodontitis patients with CVD, Group II: Chronic periodontitis patients without CVD and Group III: Control subjects (without chronic periodontitis and CVD). Patients with chronic periodontitis had ≥8 teeth involved with probing depth (PD) ≥5 mm involved. The control group had PD ≤ 3 mm and no CVD. Venous blood was collected from the patients and C-reactive protein levels were analyzed by immunoturbidimetry. PMN was recorded by differential count method. Results: On comparison, OHI-S Index, GI, mean PD, CRP and PMN values showed significant difference from Group I to III. CRP level was highly significant in Group I when compared with Group II and Group III. PMN level was highly significant in Group I when compared with Group III PMN level which was not significant. Conclusion: This study indicated that periodontitis may add the inflammation burden of the individual and may result in increased levels of CVD based on serum CRP levels. Thus, controlled prospective trials with large sample size should be carried out to know the true nature of the relationship if indeed one exists. PMID:24049333

The purpose of this experimental study is to investigate and compare the effects of prosthetic materials used for wound healing of abdominal wall hernias. A total of 60 rats were divided into five equal groups: Group I, control subjected to laparotomy; group II, abdominal wall defect 3×2 cm+polypropylene (PP) mesh; group III, abdominal wall defect 3×2 cm+PP mesh+hyaluronate and carboxymethylcellulose (H-CMC; Seprafilm®); group IV, abdominal wall defect 3×2 cm+polytetrafluoroethylene (PTFE; Composix™); and group V, abdominal wall defect 3×2 cm+polyethylene terephthalate (PET; Dacron®). A total of 14 days after the surgery, rats were sacrificed and the meshes with the surrounding tissue were extracted in block. The breaking strength of the mesh from the fascia was recorded. The healing tissue was examined with the index of histopathology and the hydroxyproline value was analyzed using the Switzer method. Both the breaking strength and histopathological index of the wound healing were significantly improved in groups II and III compared with that in groups IV and V (P<0.001). Hydroxyproline values were the highest in group I (P<0.001). There was also a statistically significant difference between groups II and IV, and group V and the other groups (P<0.001). The present findings demonstrated that PP mesh and PP mesh+H-CMC had a superior breaking strength and improved histopathologic indices compared with PTFE and PET. Furthermore, hydroxyproline values were the lowest in the PET group. In conclusion, wound healing was improved in the PP mesh group and the PP mesh+H-CMC group compared with the PTFE and PET groups according to the present study parameters. PMID:29399133

To evaluate the effect of Star Wars music (SWM) compared with endoscopist-selected popular music (PM) on quality outcomes in colonoscopy. A single-centre, prospective, randomised controlled trial conducted in an endoscopy suite within a quaternary-centre gastroenterology unit, Melbourne, Australia. The primary outcome measures were procedure time, polyp detection rate (PDR) and adenoma detection rate (ADR). The secondary outcome measure was adenomas per colonoscopy (APC). 103 colonoscopies were analysed: 58 in the SWM group and 45 in the PM group. Bowel preparation was assessed as good or excellent in 57% of the SWM group compared with 69% of the PM group (P < 0.01). The PDR was significantly higher in the SWM group than in the PM group (60% v 35%; P = 0.006). Similarly, the ADR was significantly higher in the SWM group than in the PM group (48% v 27%; P = 0.01). The APC in the SWM group was 84% compared with 35% in the PM group (P = 0.01). SWM compared with PM improves key quality outcomes in colonoscopy, despite poorer bowel preparation.

This study was designed to investigate the antioxidant effects of Naringin, in ischemia/reperfusion (I/R)-induced skeletal muscle injury in rats. The rats were randomly allocated into three groups including control, I/R and I/R + Naringin groups. Muscle tissues of I/R groups revealed significantly higher antioxidant enzyme activities, and increased levels of malondialdehyde, as specific a marker of the lipid peroxidation and tissue damage, compared to the control group (p < 0.05). Levels of these parameters in muscle revealed significant reductions in the I/R + Naringin group compared to the I/R group (p < 0.05). Histopathological examination of ischemia muscles in the I/R group showed significant degeneration and inflammation compared to the control group, whereas ischemic muscles of Naringin-administered group showed significant reduction in degeneration and inflammation compared to the I/R group (p < 0.05). We suggest that the protective effect of Naringin may reduce the I/R injury in cases of extremity injuries with acute vascular complications, extremity surgery with prolonged tourniquet application.

Laparoscopic intestinal anastomosis is not very reliable and needs to be evaluate in an experimental model in animals before being performed in man. The purpose of this study was to evaluate the feasibility, efficacy and safety of manual anastomosis comparatively to the standard stapling suture. Twenty female pigs weighing 20 +/- 5 kg. were used for this study. A 5 cm ileal segment resection was performed under laparoscopy. The animals were assigned to 2 groups. Group I: 10 animals underwent end-to-end hand-swen anastomosis with Polyglactin 910, dec 1.5. Group II: 10 animals underwent side-to-side anastomosis using the Endo stapler. Operating time and anastomosis time were compared using the Mann-Whitney test for statistical analysis. On the 15th postoperative day, the animals were sacrificed and the anastomoses were evaluated. There was no operating death in the 2 groups. The operative time was significantly longer in group I than in group II (p < 0.01), with 180 +/- 40 min vs 49 +/- 25 min respectively. This difference was due to the anastomosis time of 130 +/- 40 min vs 16 +/- 6 min respectively (p < 0.01). There was 1 postoperative death related to fistula and peritonitis in group I and none in group II. The post-operative follow-ing showed 5 anastomotic leakages (4 in group I and 1 in group II) and 2 relative stenoses in group I. This study shows the simplicity and rapidity of performing stapling intestinal anastomosis under laparoscopy. Hand-sewn anastomosis is technically more difficult to perform under laparoscopy and requires a greater experience.

Small studies have shown that South Asians (SAs) have more total body, subcutaneous, visceral and hepatic fat and abnormal adipokine levels compared with Whites. However, comprehensive studies of body composition and adipokines in SAs compared with other ethnic groups are lacking. Using harmonized data, we performed a cross-sectional analysis of two community-based cohorts: Mediators of Atherosclerosis of South Asians Living in America (MASALA, n=906) and Multi-Ethnic Study of Atherosclerosis (MESA which included 2622 Whites, 803 Chinese Americans, 1893 African Americans and 1496 Latinos). General linear models were developed to assess the ethnic differences in ectopic fat (visceral, intermuscular and pericardial fat; and hepatic attenuation), lean muscle mass and adipokines (adiponectin and resistin). Models were adjusted for age, sex, site, alcohol use, smoking, exercise, education, household income and body mass index. Ectopic fat models were additionally adjusted for hypertension, diabetes, high-density lipoprotein and triglycerides. Adipokine models were adjusted for subcutaneous, visceral, intermuscular and pericardial fat; and hepatic attenuation. Compared with all ethnic groups in MESA (Whites, Chinese Americans, African Americans and Latinos), SAs had greater intermuscular fat (pairwise comparisons with each MESA group, P<0.01), lower hepatic attenuation (P<0.001) and less lean mass (P<0.001). SAs had greater visceral fat compared with Chinese Americans, African Americans and Latinos (P<0.05) and greater pericardial fat compared with African Americans (P<0.001). SAs had lower adiponectin levels compared with other ethnic groups (P<0.01; except Chinese Americans) and higher resistin levels than all groups (P<0.001), even after adjusting for differences in body composition. There are significant ethnic differences in ectopic fat, lean mass and adipokines. A less favorable body composition and adipokine profile in SAs may partially explain the increased predisposition to cardiometabolic disease. The mechanisms that underlie these differences warrant further investigation.

To compare the surgical proficiency of medical students who underwent traditional training or virtual reality training for argon laser trabeculoplasty with the PixEye simulator. The cohort comprised of 47 fifth year male medical students from the College of Medicine, King Faisal University, Saudi Arabia. The cohort was divided into two groups: students (n = 24), who received virtual reality training (VR Group) and students (n = 23), who underwent traditional training (Control Group). After training, the students performed the trabeculoplasty procedure. All trainings were included concurrent power point presentations describing the details of the procedure. Evaluation of surgical performance was based on the following variables: missing the exact location with the laser, overtreatment, undertreatment and inadvertent laser shots to iris and cornea. The target was missed by 8% of the VR Group compared to 55% in the Control Group. Overtreatment and undertreatment was observed in 7% of the VR Group compared to 46% of the Control Group. Inadvertent laser application to the cornea or iris was performed by 4.5% of the VR Group compared to 34% of the Control Group. Virtual reality training on PixEye simulator may enhance the proficiency of medical students and limit possible surgical errors during laser trabeculoplasty.

The purpose of this study was to compare the effect of naringin 100mg/kg in combination with pravastatin 10mg/kg by gavage for 6weeks compared with monotherapy over lipid profiles, glucose levels and weight in murine model of obesity. The study design was planned with 5 groups of 6 male Wistar Albina rats: Group 1: control with balanced food and vehicle (C-); Group 2: control with Obesity and vehicle (C+); Group 3: Obesity+naringin (N); Group 4: Obesity+pravastatin (P); Group 5: Obesity+pravastatin+naringin (NP). Obesity was developed with a food model. The naringin groups showed a decrease in weight gain and low glucose values compared to the control group (weight NP:311.4 vs C+:348.6; glucose NP: 173.12 vs C+:235.56) (p<0.05); the group with naringin+pravastatin combination showed the total cholesterol (TC), LDL and triglycerides (TGs) to normal levels (TC NP:51.6 vs C+:83.4; LDL NP:9.32 vs C+:32.32; TGs NP:39.4 vs C+:89.4) (p<0.05); but was not statistically significant compared with monotherapy. The combination of naringin and pravastatin did not appear to be better than monotherapy on lipids, but its use could generate euglycemic and antiobesogenic effects, in addition to diminishing the adverse hepatic effects of pravastatin in rats.

To clarify the cardioprotective effects of a short course of vitamin E treatment (vit E) as compared with a nitric oxide donor, nitroglycerin (GTN) against ischemia-reperfusion induced heart injury in rats. This randomized control study was conducted in the Physiology Department, Faculty of Medicine, Ain Shams University, Cairo, Egypt from 1st June to 31 August 2009. This work was undertaken on 28 female Wistar rats weighing 150- 200 gm. Rats were allocated into 4 groups; control group (non-treated), GTN-treated group (rats received GTN intraperitoneally 25 minutes before sacrifice, in a dose of 120 ug/kg body weight), vit E-treated group (rat received vit E by oral tubal feeding 16-20 hours before sacrifice, in a dose of 250 mg/rat), and vit E and GTN-treated group (rats received vit E and GTN as in both GTN-treated group and vit E -treated group). After sacrifice, the hearts were excised and perfused in a Langendorff preparation and subjected to 30 minutes global ischemia and reperfused for 30 minutes. Following reperfusion, heart tissues were used for assessment of malondialdehyde (MDA) and nicotinamide adenine dinucleotide (NAD)+, and for histological examination. Vitamin E treatment resulted in an enhanced post-ischemic recovery of systolic function in vit E-treated groups (vit E-treated group, and vit E and GTN-treated group) compared to the control group. Post-ischemic recovery of coronary flow was enhanced in the vit E-treated group compared to the GTN-treated group. Post ischemic tissue degeneration indicators: MDA, and NAD+ indicated a cardioprotective effect of vit E. Histological study revealed marked improvement of myocytes and mitochondrial structure in the vit E-treated group as compared with the control group. Preconditioning with vit E treatment afforded substantial recovery of post-ischemic contractile, and vascular functions compared to GTN treatment, the mechanism might involve less opening of mitochondrial permeability transition during postischemic reperfusion.

This study was to evaluate the effects of foot reflexology on blood pressure, serum lipids level and life satisfaction in essential hypertension patients. The research design used was a nonequivalent control group pretest-posttest design. Foot Reflexology was used as the experimental treatment from June 23rd, 2003 until August 31st, 2003. Thirty-four subjects were assigned to an experimental group(18) and control group(16). Foot Reflexology was administered twice a week for 6 weeks and self foot Reflexology was administered twice a week for 4 weeks on the experimental group. There was a significant decrease in systolic blood pressure but no significant decrease in diastolic pressure in the experimental group compared to the control group. The total cholesterol level in the experimental group compared to the control group was not significantly decreased after foot reflexology. However, the triglyceride level in the experimental group compared to the control group was significantly decreased after foot reflexology. On the other hand, high density lipoprotein and low density lipoprotein levels in the experimental group compared to the control group was not significantly decreased after foot reflexology. Life satisfaction in the experimental group compared to the control group was significantly improved after foot reflexology. The results proved that foot reflexology was an effective nursing intervention to decrease systolic pressure, and triglyceride but not for the blood cholesterol and to improve life satisfaction. Therefore, blood cholesterol should be further evaluated in a larger group of subjects and for a longer period. Further research is regarded as necessary to evaluate and to compare effects of self-foot reflexology and foot reflexology.

The effect of postmilking teat dipping with a foaming iodophor agent on incidence of intramammary infections (IMI), incidence of clinical mastitis, somatic cell count and the characteristics of udder tissue and teat was investigated in a positively controlled field study. Two groups of animals were compared. Teats were dipped with a foaming iodophor in the treatment group (TG, 122 animals) while teats in the control group (CG, 121 animals) were dipped with a conventional iodophor teat dip with the same iodine content. A bacteriological examination of quarter milk samples divided the study period in two parts. The incidence of new IMI did not differ between the groups (1st part of trial: TG vs. CG: 6.84% vs. 9.16%, 2nd part of trial: 7.78% vs. 7.82%). There were no differences between the treatment groups regarding incidence of clinical mastitis. We detected 0.64 clinical cases per 100 days in the treatment group vs. 0.50 in the control group. The development of SCC was comparable in both groups. Teat skin and teat duct conditions showed variation during the study period. Clinical efficacy of postmilking teat disinfection with a foaming iodophor was comparable to the treatment with a conventional iodophor product.

To compare two different approaches to performing focus groups and individual interviews, an open approach, and an approach based on the International Classification of Functioning, Disability and Health (ICF). Patients with rheumatoid arthritis attended focus groups (n = 49) and individual interviews (n = 21). Time, number of concepts, ICF categories identified, and sample size for reaching saturation of data were compared. Descriptive statistics, Chi-square tests, and independent t tests were performed. With an overall time of 183 h, focus groups were more time consuming than individual interviews (t = 9.782; P < 0.001). In the open approach, 188 categories in the focus groups and 102 categories in the interviews were identified compared to the 231 and 110 respective categories identified in the ICF-based approach. Saturation of data was reached after performing five focus groups and nine individual interviews in the open approach and five focus groups and 12 individual interviews in the ICF-based approach. The method chosen should depend on the objective of the study, issues related to the health condition, and the study's participants. We recommend performing focus groups if the objective of the study is to comprehensively explore the patient perspective.

The aim of this study was to examine the presence of Candida albicans in extensive carious lesions before and after treatment of the carious lesions and to evaluate the carriage of Candida albicans in children with and without caries. The study was conducted on 60 childrens who were divided into two groups: Experimental group (group 1) and controlled group (group 2). Each group was further divided into 3 subgroups according to the dentition as: Group A (Deciduous), group B (Mixed) and group C (Permanent). Swab samples for mycological studies were collected from the dorsum of the tongue, vestibular sulcus and peak of the palatal vault. All samples were cultured directly on SDA plate (Sabouraud's dextrose agar). Number of Candida colonies was determined by counting colony forming unit on SDA plates. Further identification of Candida albicans was done by germ-tube test and corn-meal agar. Overall prevalence of Candida albicans carriage was significantly higher and mean value of Candida albicans CFU (colony forming unit) was remarkably higher in group 1 (experimental group) as compare to group 2 (control group). Significant reduction in the frequency and mean value of Candida albicans CFU/plate was seen in children after treatment of carious lesions. This study supports the active role of Candida species in dental caries. Hence, Candida albicans may play an important role as a risk factor for dental caries. It was also seen that the oral environment stabilization procedures were able to reduce Candida albicans counts. Thus, these procedures can be considered efficient in the reduction of caries risk.

Esmolol is a highly selective beta 1 receptor blocker with various effects such as slowing heart rate, lowering blood pressure and reducing myocardial oxygen consumption. However, few studies have reported the use of beta blockers in sepsis with multiple organ dysfunctions. This study aimed to investigate the effects of esmolol on reducing apoptosis and inflammation in early sepsis rats with abdominal infection. Rats were randomly divided into sham operation group, sepsis group, antibiotic group, Esmolol + antibiotic group with low, median and high dose Esmolol (L group, M group and H group). Values between two or more groups were compared by independent t-tests. In the liver and kidney, we found inflammatory infiltration in sepsis group while pathological aspects reduced in L, M and H groups. Bcl-2 mRNA and protein levels increased while Bax mRNA and protein levels decreased in the liver and kidney of L, M and H groups. Serum IL-6, HMGB-1 and TNF-α levels decreased but IL-10 level increased in L, M and H groups, compared to sepsis group. Compared to sepsis and antibiotic groups, the levels of myocardial enzymes were lower in L, M and H groups. The administration of esmolol in early sepsis may reduce inflammation, inhibit apoptosis and protect key organs. Copyright © 2017 Elsevier Inc. All rights reserved.

The aim of this randomized, double-blind, controlled study was to evaluate the antidandruff activity exerted by a new shampoo on patients affected by dandruff and/or mild seborrheic dermatitis by means of both D-squame technique coupled with image analysis and clinical assessments. Thirty-four patients were enrolled and 1:1 randomly assigned to either a test shampoo or a comparative shampoo group. Treatment schedule was twice a week for 4 weeks. The D-squame technique was shown to be able to objectively record variations in scalp desquamation both between test and comparative groups and within the same group over time. The results obtained with this instrumental approach showed a statistically significant reduction by 52% vs baseline after 2 weeks of treatment. There was an even greater reduction after 4 weeks (-66%). This reduction was statistically significant compared with the comparative group at the same time points. The analysis of all the other parameters (except Wood's lamp) confirmed the superiority of the test vs the comparative shampoo. The test shampoo proved to be safe, well tolerated, and accepted by the patients for cosmetic acceptability and efficacy. The study confirmed the antidandruff efficacy of the test shampoo and its superiority vs the comparative shampoo.

This study tested the maintenance outcomes of a 3-month Sit Less, Walk More (SLWM) workplace intervention for office workers compared with usual care at 12 months from the baseline. A quasi-experimental study was conducted in two workplaces. The intervention group (n = 51) received multi-component intervention and the comparison group (n = 50) received newsletters only. The outcomes of the study (self-reported psychosocial, physical activity, sitting, and lost productivity; objectively measured cardiometabolic biomarkers) were compared at baseline, 3, and 12 months. Generalized estimating equations analyses found that the intervention group had significant improvements in self-regulation for sitting less and moving more (P = 0.017), walking (P = 0.003), weight (P = 0.013), waist circumference (P = 0.002), and insulin (P = 0.000) at 12 months compared with the comparison group. The SLWM intervention was effective in improving self-regulation, walking, and some cardiometabolic biomarkers in office workers.

Amputation and chemotherapy are the mainstay of treatment for canine appendicular osteosarcoma (OSA). In vitro studies have demonstrated anti-tumour activity of pamidronate against canine OSA. The purpose of this study was to assess the safety of adding pamidronate to standard post-operative carboplatin chemotherapy in 17 dogs with appendicular OSA treated with limb amputation. Median disease-free interval (DFI) and median survival time (MST) were evaluated as secondary endpoints. Incidence of side effects and treatment outcomes were compared to 14 contemporary control patients treated with carboplatin alone. There were no identified side effects to the pamidronate treatment. The median DFI for the study group was 185 days compared to 172 days for the control group (P = 0.90). The MST of the study group was 311 days compared to 294 days for the control group (P = 0.89). Addition of pamidronate to carboplatin chemotherapy for the treatment of canine appendicular OSA is safe and does not impair efficacy of standard carboplatin treatment. © 2013 Blackwell Publishing Ltd.

To compare the survival of dogs with completely resected massive hepatocellular carcinoma (HCC) with that of dogs in which HCC were incompletely excised. A retrospective cohort study was conducted. Dogs that underwent surgical excision of massive HCC between November 2006 and April 2015 were included. Dogs that died in the perioperative period or were lost to follow-up within 2 months after surgery were excluded. Data were collected from the medical records and a single pathologist examined all available histology slides to confirm the diagnosis of HCC. Surgical margins were defined as complete if no neoplastic cells were seen at the edge of excised tissues, based on original histopathology reports. Progression-free survival (PFS) and overall survival (OS) were compared between dogs with complete surgical margins (CM) and those with incomplete margins (IM) using a log-rank test. Of the 37 dogs included in the study, 25 were allocated to the CM group and 12 to the IM group. Progressive local disease developed after surgery in three dogs in the CM group and seven dogs in the IM group. Three dogs in the CM group and five dogs in the IM group died due to tumour progression. Median PFS was longer for dogs in the CM group (1,000 (95% CI=562-1,438) days) compared to dogs in the IM group (521 (95% CI=243-799) days; p=0.007). OS was also longer for dogs in the CM group (>1,836 days) compared to those in the IM group (median 765 (95% CI=474-1,056) days; p=0.02). Compared with complete resection, incomplete resection decreased PFS and OS in dogs with massive HCC. Dogs with incompletely excised HCC should be closely monitored for local recurrence, although median OS was >2 years following incomplete excision. Further prospective studies are warranted to confirm these findings.

To gain insight into the ovarian stromal blood flow in women with polycystic ovary syndrome (PCOS) as compared with women with normal ovulation, good ovarian reserve, and infertility and to evaluate the role of stromal flow in these patients to predict clinical pregnancy in an assisted reproductive technologies setting. A prospective observational cohort study. A university-affiliated reproductive medicine unit. Eighteen consecutive patients with PCOS (study) compared with 101 patients with normal ovulation and infertility (control), undergoing their first IVF-ET treatment at our unit. Women with low ovarian reserve were excluded a priori from evaluation. Basal ovarian reserve parameters and stromal flow studies were conducted as routinely performed in our unit, in a natural cycle before starting treatment. None. Basal ovarian endocrine, sonographic, and stromal flow studies were compared between the groups. After completion of treatment, the stromal flow studies were compared between conception and nonconception cycles. Patients' characteristics and basal ovarian reserve, including endocrine and sonographic parameters, were similar between the PCOS and control groups. Only antral follicle count and LH/FSH ratio were higher in the PCOS as compared with the control group, corresponding to 15.11 ± 6.05 versus 9.05 ± 4.77 and 1.14 ± 0.64 versus 0.79 ± 0.37, respectively. Basal stromal flow indices were similar between the PCOS group and the group with normal ovulation and good ovarian reserve. Clinical pregnancy rate per initiated cycle was 50.0% and 39.6% in the PCOS and control groups, respectively, with no significant difference. Flow indices were similar between conception cycles in the PCOS and control groups. As well, the indices did not differ significantly between conception and nonconception cycles within the PCOS and control groups. Basal ovarian stromal blood flow does not differ between women with PCOS and women with normal ovulation, good ovarian reserve, and infertility. Moreover, stromal flow has no predictive value, in these patients, for clinical pregnancy achievement in an IVF-ET setting. Copyright © 2011 American Society for Reproductive Medicine.

The aim of this study was to assess the correlation between fetal lateral ventricle width and biometric measurements. A prospective study on 335 fetuses, 101 fetuses with isolated mild ventriculomegaly and a control group of 234 fetuses with a normal US examination. All fetuses underwent a detailed brain ultrasound scan and a full biometric evaluation. To further compare biometric parameters, we matched, according to gestational week and gender, 91 fetuses from the study group to 91 fetuses from the control group. The mean gestational week during the exam was significantly different between the groups (29.6 weeks in the study group versus 28.3 in the control group, p = .001). The mean maternal age, obstetrical history, mode of conception, or fetal gender did not differ between the groups. After matching according to gestational age and fetal gender, the mean gestational week between the matched groups did not differ and was 29 + 5 weeks in both groups. The study group had significantly larger head circumference (p = .009), biparietal diameter (p < .001), femur length (p = .023), and estimated fetal weight (p = .024) compared with the control group. Isolated mild ventriculomegaly could be related to other larger fetal biometric measurements and does not necessarily mean a pathological condition.

Objectives: To compare the effectiveness of laparoscopic common bile duct exploration in patients with failed endoscopic retrograde cholangiopancreatography (ERCP). Methods: This is a descriptive, comparative study. Patients with an indication of common bile duct exploration between February 2005 and October 2008 were included. We studied 2 groups: Group A: patients with failed ERCP who underwent LCBDE plus LC. Group B: patients with common bile duct stones managed with the 1-step approach (LCBDE + LC) with no prior ERCP. Results: Twenty-five patients were included. Group A: 9 patients, group B: 16 patients. Success rate, operative time, and hospital stay were as follows: group A 66% vs group B 87.5%; group A 187 minutes vs 106 minutes; group A 4.5 days vs 2.3 days; respectively. Conclusion: Patients with failed ERCP should be considered as high-complex cases in which the laparoscopic procedure success rate decreases, and the conversion rate increases considerably.

The aim of the study was to compare the incidences of pharyngocutaneous fistula after total laryngectomy between patients who underwent manual and mechanical suturing for pharyngoesophageal closure. In a retrospective and prospective nonrandomized clinical study conducted at a single tertiary medical center between May 2002 and April 2009, we compared the incidence of pharyngocutaneous salivary fistula between two groups of patients after total laryngectomy. Sixty-one consecutive patients who underwent mechanical suturing with a 60-mm linear stapler (group A) were prospectively enrolled, and 121 patients who had undergone manual suturing (group B) were retrospectively reviewed. The groups were similar in terms of age, gender, comorbidities, TNM (tumor, node, metastasis) stage, and laryngeal tumor extension. The incidence of pharyngocutaneous salivary fistula was 4.9% in group A and 19.8% in group B (p = 0.014). Mechanical stapler closure of the pharynx after total laryngectomy was associated with a significant reduction in the incidence of pharyngocutaneous fistula compared with manual suture in selected cases.

ABSTRACT Objective: To compare the functional results of ankle fractures treated with metallic and absorbable plates. Twenty patients were randomized into two groups (metallic and absorbable implant groups) and followed prospectively. In the immediate postoperative period, patients were immobilized with plaster casts for one week, which was replaced by a removable cast for another four weeks. Partial weight-bearing was allowed after three weeks, and full weight-bearing after six weeks. Functional recovery was similar in both groups. At six months, three patients in the metallic group complained of local pain, and had their implants removed. One patient in the absorbable group exhibited early dehiscence of the suture and underwent debridement and suturing with good evolution. The American Orthopaedic Foot and Ankle Society (AOFAS) score was similar between the two groups after six and nine months of follow-up. The absorbable implants showed clinical and functional results that were similar to those of metallic implants. Level of Evidence II, Prospective Comparative Study. PMID:26981035

Interventions for people suffering from borderline personality disorder (BPD), such as dialectical behavior therapy, often include a problem-solving component. However, there is an absence of published studies examining the problem-solving abilities of this client group in Iran. The study compared inpatients and outpatients with BPD and a control group on problem-solving capabilities in an Iranian sample. It was hypothesized that patients with BPD would have more deficiencies in this area. Fifteen patients with BPD were compared to 15 healthy participants. Means-ends problem-solving task (MEPS) was used to measure problem-solving skills in both groups. BPD group reported less effective strategies in solving problems as opposed to the healthy group. Compared to the control group, participants with BPD provided empirical support for the use of problem-solving interventions with people suffering from BPD. The findings supported the idea that a problem-solving intervention can be efficiently applied either as a stand-alone therapy or in conjunction with other available psychotherapies to treat people with BPD.

Adenosine is an effective treatment for androgenetic alopecia (AGA) in Japanese men and women. Adenosine exerts its effects by significantly increasing the proportion of thick hair. In this study, we assessed the clinical outcome of adenosine treatment for 6 months in 38 Caucasian men. The change in proportion of thick hair (≥60 μm) compared with baseline in the adenosine group was significantly higher than that in the placebo group (P < 0.0001). The change in vellus hair proportion (<40 μm) was significantly lower in the adenosine group than that in the placebo group (P = 0.0154). The change in hair density compared with baseline of the adenosine group was also significantly higher compared with that of the placebo group (P = 0.0470). No adverse effects due to treatment were noted during this study by dermatological evaluation. Adenosine is effective in increasing the proportion of thick hair in Caucasian men with AGA as well as in Japanese men and women. © 2015 Japanese Dermatological Association.

Organophosphorus compound poisoning (OPCP) is a major public health problem in developing countries like India. Atropine and oximes remain the main-stay of management. Magnesium sulfate (MgSO 4 ) has shown benefit in the management of OPCP. This study was designed to assess the effect of MgSO 4 on outcome in OPCP patients admitted to Intensive Care Unit (ICU). Double-blind prospective randomized clinical trial in an ICU of tertiary care institution. One hundred patients (50 in each group) of OPCP, confirmed by history and syndrome of OPCP with low plasma pseudocholinesterase, aged between 18 and 60 years were studied. Magnesium group (Group M) received 4 g of 20% MgSO 4 infusion over 30 min at admission to ICU, control group (Group C) received normal saline placebo in the same manner. Patients were assessed for the need for intubation, requirement of atropine, duration of mechanical ventilation, duration of ICU stay, and its effect on mortality. Chi-square test and Fisher's exact test for categorical data, independent sample t -test, and paired t -test for nominal data. Demographics and basal serum magnesium levels were comparable. Atropine requirement was higher in Group C (74.82 ± 22.39 mg) compared to Group M (53.11 ± 45.83 mg) ( P < 0.001). A total of 33 patients in Group C and 23 patients in Group M required intubation, respectively ( P = 0.043). The mean duration of mechanical ventilation was 4.51 ± 2 days in Group C compared to 4.13 ± 1.6 days in Group M ( P = 0.45). ICU stay was 5.36 ± 2.018 days in Group C compared to 4.54 ± 1.581 days in Group M ( P = 0.026). There was no significant difference in mortality between the groups. Four grams of MgSO 4 given to OPCP patients within 24 h of admission to ICU, decreases atropine requirement, need for intubation, and ICU stay.

Several studies have demonstrated that non-O blood groups subjects present an increased VTE risk as compared to those carrying O blood group. The aim of this study was to investigate the ABO blood groups influence on factor VIII (FVIII) activity, von Willebrand factor (VWF), and ADAMTS13 plasma levels in patients undergoing hemodialysis (HD). Patients undergoing HD (N=195) and 80 healthy subjects (control group) were eligible for this cross-sectional study. The ABO blood group phenotyping was performed by the reverse technique. FVIII activity was measured through coagulometric method, and VWF and ADAMTS13 antigens were assessed by ELISA. FVIII activity and VWF levels were significantly higher and ADAMTS13 levels was decreased in HD patients, as compared to healthy subjects (P < 0.001, in three cases). HD patients carrying non-O blood groups showed a significant increase in FVIII activity (P = 0.001) and VWF levels (P < 0.001) when compared to carriers of O blood group. However, no significant difference was observed in ADAMTS13 levels (P = 0.767). In the control group, increased in FVIII activity (P = 0.001) and VWF levels (P = 0.002) and decreased in ADAMTS13 levels (P = 0.005) were observed in subjects carrying non-O blood groups as compared to carriers of O blood group.Our data confirmed that ABO blood group is an important risk factor for increased procoagulant factors in plasma, as FVIII and VWF. Admitting the possible role of kidneys in ADAMTS13 synthesis or on its metabolism, HD patients were not able to increase ADAMTS13 levels in order to compensate the increase of VWF levels mediated by ABO blood groups. Considering that non-O blood groups constitute a risk factor for thrombosis, it is reasonable to admit that A, B and AB HD patients need a careful and continuous follow-up in order to minimize thrombotic events.

Farion K, Osmond MH, Hartling L, et al. Tissue adhesives for traumatic lacerations in children and adults. Cochrane Database Syst Rev. 2001(4);CD003326. What is the clinical evidence base for tissue adhesives in the management of simple traumatic lacerations? Studies were identified by searches of the following databases: Cochrane Wounds Group Specialized Trials Register (September 2003), Cochrane Central Register of Controlled Trials (CENTRAL) (CDROM 2003, issue 3), MEDLINE (1966 to September 2003, week 1), EMBASE (1988 to 2003, week 36), Web of Science Science Citation Index (1975 to September 13, 2003) and various clinical trials registers (September 2003). Investigators and product manufacturers were contacted to identify additional eligible studies. The search terms included wounds and injuries, laceration, face injury, nose injury, tissue adhesives, and acrylates. Each study fulfilled the following criteria: (1) The study was a randomized controlled trial that compared tissue adhesives with standard wound closure (SWC) (sutures, staples, adhesive strips) or tissue adhesive with tissue adhesive. (2) The wounds were acute, linear lacerations less than 12 hours old, resulting from blunt or sharp trauma. (3) The wound length, width, and depth allowed for approximation of the edges with minimal tension after deep sutures were placed, if required. Studies were included with no language or publication status restriction, with participants of any age recruited in an emergency department, outpatient clinic, walk-in clinic, or other primary care setting. Studies were excluded if the wounds were stellate lacerations, puncture wounds, mammalian bites, infected, heavily contaminated or devitalized, crossing joints or mucocutaneous junctions, in hair-bearing areas, or in patients with keloid formation or chronic illness. The characteristics of the study and participants, interventions, outcome measures, and findings were extracted by one author and verified by a second using a standard form. The primary measure was cosmetic outcome. Secondary measures were pain with the procedure, time to complete the procedure, and complications (erythema, infection, discharge, need for delayed closure, and dehiscence). Studies were divided into 2 groups as follows: group 1, comparisons among tissue adhesives with SWC, and group 2, comparisons among different tissue adhesives. All eligible studies were assessed for methodologic quality independently by 2 investigators using the Jadad Scale, which evaluates randomization, double blinding, withdrawals, and dropouts and is scored on a 5-point (maximum) scale. The data from the tissue adhesive and SWC studies were pooled and analyzed with a random-effects model. The I (2) statistic was used to determine heterogeneity among the studies. chi (2) analysis was performed to compare participant age, wound location, and type of tissue adhesive among the studies. The data from the studies comparing tissue adhesives were pooled and analyzed using a fixed-effects model. The search criteria identified 39 eligible studies, of which 11 met the inclusion criteria. In 10 studies, a tissue adhesive was compared with SWC. Five groups used butylcyanoacrylate, and 5 used octylcyanoacrylate. For SWC, 6 groups used sutures, 2 used adhesive strips, and 2 used a combination of methods, although most used sutures. Six studies were limited to pediatric patients and 2 to adult patients; 2 included patients of any age. Wounds were limited to facial lacerations in 2 pediatric studies and 1 group with patients of any age. Lacerations requiring deep sutures were excluded in 4 studies. One group compared tissue adhesives (butylcyanoacrylate and octylcyanoacrylate) among pediatric patients with facial lacerations not requiring deep sutures. In the 11 included studies, authors of 9 randomized and evaluated 1 laceration per patient, whereas 2 groups included patients with more than 1 laceration. In 1 group, each laceration was independently randomized and evaluated, and the other group randomized the patient and assigned all lacerations to a treatment group (tissue adhesive with SWC or tissue adhesive with tissue adhesive). The sample sizes ranged between 60 and 163 lacerations, and all 11 studies were performed in emergency departments. The primary measure in all included studies was cosmetic outcome. The majority of groups used the Cosmetic Visual Analogue Scale, the Wound Evaluation Score, or a combination of these measures. Three groups measured cosmetic outcome with nonvalidated scoring systems. Assessment time periods were grouped and reported at (1) 5 to 14 days, (2) 1 to 3 months, and (3) 9 to 12 months after wound closure. Secondary outcomes were pain (as noted on visual analogue scale) and time to complete the procedure (as mean number of minutes). The 11 studies scored from 1 to 3 on the Jadad Scale. Adequate allocation concealment was reported in only 1 group. Examining cosmetic outcome, 8 groups (565 lacerations) used the Cosmetic Visual Analogue Scale to compare tissue adhesives and SWC. The authors reported no significant differences in scores at the time periods of 5 to 14 days, 1 to 3 months, and 9 to 12 months. A subgroup analysis showed a significant ( P = .005) superiority of butylcyanoacrylate over SWC at 1 to 3 months. Using the Wound Evaluation Score, 4 studies (364 lacerations) compared tissue adhesives with SWC. No significant differences in cosmetic scores were found at 5 to 14 days, 1 to 3 months, or 9 to 12 months. One group (83 lacerations) compared butylcyanoacrylate with octylcyanoacrylate and reported no significant differences in cosmetic scores using the Cosmetic Visual Analogue Scale at 1 to 3 months and the Wound Evaluation Score at 5 to 14 days and 1 to 3 months. Examining secondary outcomes, 6 groups (570 lacerations) compared tissue adhesives with SWC using the visual analogue scale for pain. Scores reported by parents, patients, physicians, and nurses significantly favored tissue adhesives. In 6 studies (584 lacerations), tissue adhesives were significantly favored over SWC in time to complete the procedure. For complication outcomes, 8 groups (727 lacerations) demonstrated significantly fewer incidences of erythema and an increased risk of dehiscence with tissue adhesives compared with SWC. No significant differences were shown for infection, delayed closure, or discharge. Among 83 lacerations, 1 group compared butylcyanoacrylate with octylcyanoacrylate and reported no significant differences in combined patient-reported and parent-reported visual analogue pain scores, time to complete the procedure, dehiscence, or infection. This review provides evidence that tissue adhesives are an option to SWC (sutures, staples, adhesive strips) for the management of simple traumatic lacerations. Overall, no significant differences were found in cosmetic scores at the reported assessment periods between tissue adhesives and SWC. At 1 to 3 months, a subgroup analysis significantly favored butylcyanoacrylate over SWC. Tissue adhesives significantly lowered the time to complete the procedure, levels of pain, and rate of erythema. However, the data revealed a significant increase in the rate of dehiscence with the use of tissue adhesives when compared with SWC. The low methodologic quality of the evidence should be considered in the interpretation of the findings.

Can the Fatigue Severity Scale 7-item version be used across different patient populations as a generic fatigue measure - a comparative study using a Rasch model approach

PubMed Central

2014-01-01

Background Fatigue is a disabling symptom associated with reduced quality of life in various populations living with chronic illnesses. The transfer of knowledge about fatigue from one group to another is crucial in both research and healthcare. Outcomes should be validly and reliably comparable between groups and should not be unduly influenced by diagnostic variations. The present study evaluates whether the Fatigue Severity Scale 7-item version (FSS-7) demonstrates similar item hierarchy across people with multiple sclerosis, stroke or HIV/AIDS to ensure valid comparisons between groups, and provide further evidence of internal scale validity. Methods A secondary comparative analysis was performed using data from three different studies of three different chronic illnesses: multiple sclerosis, stroke and HIV/AIDS. Each of these studies had previously concluded that the FSS-7 has better psychometric properties than the original FSS for measuring fatigue interference. Data from 224 people with multiple sclerosis, 104 people with stroke and 316 people with HIV/AIDS were examined. Item response theory and a Rasch model were chosen to analyze the similarity of the FSS-7 item hierarchy across the three diagnostic groups Results Cross-sample differences were found for items #3, #5, #6 and #9 for two of the three samples, which raise questions about item validity across groups. However, disease-specific and disease-generic Rasch measures were similar across samples, indicating that individual fatigue interference measures in these three chronic illnesses might still be reliably comparable using the FSS-7. Conclusions Some items performed differently between the three samples but did not bias person measures, thereby indicating that fatigue interference in these illnesses might still be reliably compared using FSS-7 scores. However, caution is warranted when comparing fatigue raw sum scores directly across diagnostic groups using the FSS-7. Further studies of the scale are needed in other types of chronic illnesses.

Anterior plate fusion is an effective procedure for the treatment of cervical spinal diseases but is accompanied by a high incidence of postoperative dysphagia. A zero profile (Zero-P) spacer is increasingly being used to reduce postoperative dysphagia and other potential complications associated with surgical intervention. Studies comparing the Zero-P spacer and anterior plate have reported conflicting results. A meta-analysis was conducted to compare the safety, efficacy, radiological outcomes and complications associated with the use of a Zero-P spacer versus an anterior plate in anterior cervical spine fusion for the treatment of cervical spinal disease. We comprehensively searched PubMed, Embase, the Cochrane Library and other databases and performed a meta-analysis of all randomized controlled trials (RCTs) and prospective or retrospective comparative studies assessing the two techniques. Ten studies enrolling 719 cervical spondylosis patients were included. The pooled data showed significant differences in the operation time [SMD = -0.58 (95% CI = -0.77 to 0.40, p < 0.01)] and blood loss [SMD = -0.40, 95% CI (-0.59 to -0.21), p < 0.01] between the two groups. Compared to the anterior plate group, the Zero-P group exhibited a significantly improved JOA score and reduced NDI and VAS. However, anterior plate fusion had greater postoperative segmental and cervical Cobb's angles than the Zero-P group at the last follow-up. The fusion rate in the two groups was similar. More importantly, the Zero-P group had a lower incidence of earlier and later postoperative dysphagia. Compared to anterior plate fusion, Zero-P is a safer and effective procedure, with a similar fusion rate and lower incidence of earlier and later postoperative dysphagia. However, the results of this meta-analysis should be accepted with caution due to the limitations of the study. Further evaluation and large-sample RCTs are required to confirm and update the results of this study.

In this open label, randomized study we compared the influence of a dose-reduced oral contraceptive containing 20 microg ethinyl estradiol (EE) and 100 microg levonorgestrel (20 EE) with a reference preparation containing 30 microg EE and 150 microg levonorgestrel (30 EE) on hemostatic, lipids, and carbohydrate metabolism variables. Data from 48 volunteers were obtained. The direction of the change (increase or decrease) in most of the hemostatic variables were similar in both treatment groups. In particular, prothrombin fragment 1 + 2 increased during treatment, reaching a median percent change of 40% in the 20 EE group and of 17% in the 30 EE group after one year. D-Dimer fibrin split products remained virtually unchanged, with no change at Cycle 13. The median HDL2 cholesterol levels decreased by 26% in the 20 EE group and by 39.8% in 30 EE group (p = 0.0045 for group difference) after one year. The median one year change for LDL cholesterol was 3.23% in the 20 EE group, compared to 25% in the 30 EE group, for VLDL 11.1% compared to 38.8%, respectively, and for total triglycerides 10.0% compared to 37.5%, respectively. The median absolute change for the area under the curve (AUC)(0-3h) for glucose at treatment Cycle 13 was 41.25 mmol/L x min in the 20 EE group and 73.50 mmol/L x min in the 30 EE group. The AUC(0-3h) insulin at treatment Cycle 13 decreased in the 20 EE group by 1635.0 pmolL x min and increased in the 30 EE group by 11797.5 pmolL x min (p = 0.0491 for group difference). Both study treatments were safe and well tolerated by the volunteers. In conclusion, the balanced one-third dose reduction in this new oral contraceptive evoked similar effects on the hemostatic variables, but favorable results for the lipid and carbohydrate profiles.

The therapeutic effect of Traditional Chinese Medicine (TCM) on chronic obstructive pulmonary disease (COPD) has been know for numerous years; however, the mechanism of action of the beneficial effects of TCM remains to be elucidated. The present study aimed to investigate the molecular mechanisms of COPD through metabolomic analysis as well as explore the targets and intervention mechanisms of TCM therapy using the common TCM granules Bu‑Fei Jian‑Pi. COPD rat models were established using smoke inhalations and recurrent bacterial infections. Rats were then divided into three groups as follows: A1, control healthy rats; B1, COPD model; and D1, Bu‑Fei Jian‑Pi‑treated COPD rats. Following administration of the medicine, the metabolomic profile of the lung tissue of rats in each group was assessed using high‑performance liquid chromatography/quadrupole‑time‑of‑flight mass spectrometry. The results demonstrated that there was a significanlty different spectrum of metabolites in the lung tissue of the model group compared to that of the control group as well as the Bu‑Fei Jian‑Pi‑treated COPD group; in addition, following treatment with Bu‑Fei Jian‑Pi, the metabolites of COPD rats were comparable with those of the control. Notable changes were observed in 31 metabolites between the Bu‑Fei Jian‑Pi‑treated group and the model group; however, there were 13 comparable metabolites between the Bu‑Fei Jian‑Pi and control groups as well as the model and control groups. Eleven metabolites showed a negative fold change in the Bu‑Fei Jian‑Pi‑treated groups compared to concentrations in the model group; however, minimal changes were observed in phenylpyruvic acid and α‑D‑fucose expression. In conclusion, the results of the present study demonstrated that Bu‑Fei Jian‑Pi granules had beneficial effects on measured outcomes in a rat model of stable COPD, indicated by a significantly different spectrum of metabolites. This therefore indicated that the metabolites which had significantly altered expression in the model group compared with that of the control and Bu‑Fei Jian‑Pi‑treated groups may be potential biomarkers of COPD.

Previous studies have reported that regular nut consumption reduces cardiovascular disease (CVD) risk and does not promote weight gain despite the fact that nuts are energy-dense. However, no studies have investigated the body composition of those regularly consuming nuts compared to similar intakes of other snacks of equal energy density. This parallel study (n = 118) examined the effects of providing daily portions (~1100 kJ/d) of hazelnuts, chocolate, or potato crisps compared to a control group receiving no snacks for twelve weeks. Effects on body weight and composition, blood lipids and lipoproteins, resting metabolic rate (RMR), appetite indices, and dietary quality were compared. At week 12, there was no significant difference in any of the outcome measurements between the groups except for dietary quality, which improved significantly in the nut group. Nuts can be incorporated into the diet without adversely affecting body weight and can improve diet quality. PMID:21845219

The aim of this study was to assess levels of autoantibodies and cytokines in patients with Tourette's syndrome (TS, n = 40) and healthy control individuals (n = 40). Plasma interleukin (IL)-1β, IL-6, IL-17, and soluble gp130 concentrations were significantly higher in the TS group compared with the control group (P < 0.001); whereas the soluble IL-6 receptor concentration was significantly decreased in the TS group compared with the control group (P < 0.001). Significantly more patients in the TS group were positive for antibrain and antinuclear antibodies, and antistreptolysin compared with the control group (P < 0.05). These findings suggest that immune activity is altered in patients with TS.

2016-04-01

To evaluate ex vivo the possible difference in corneal cross-linking (CXL) biomechanical effect of different ultraviolet-A (UV-A) irradiances. The study involved 25 human donor corneas, randomly allocated to 5 groups (n = 5 each). CXL was applied with UV-A irradiances of 3, 9, 18, 30, and 45 mW/cm2, maintaining equal cumulative energy dose of 5.4 J/cm2. UV-A was delivered on half of the cornea. The nonirradiated halves served as controls. Specimens were subjected to collagenase-A enzymatic digestion. The time to complete dissolution in each specimen was recorded. Time to dissolution in group-A (3 mW/cm2 for 30 minutes) was 321 ± 13.4 minutes (range: 300-330) compared with 171 ± 8.2 (range: 165-180) for their control. In group-B (9 mW/cm2 for 10 minutes), it was 282 ± 19.6 minutes (range: 270-315) compared with 177 ± 6.7 (165-180) for their control. In group-C (18 mW/cm2 for 5 minutes), it was 267 ± 19.6 minutes (range: 240-285) compared with 177 ± 7.7 (range: 165-180) for their control. In group-D (30 mW/cm2 for 3 minutes), it was 252 ± 12.5 minutes (range: 240-270) compared with 180 ± 10.6 minutes (range: 165-195) for their control. In group-E (45 mW/cm2 for 2 minutes), it was 204 ± 17.1 minutes (range: 180-225) compared with 186 ± 8.2 minutes (range: 180-195) for their control. The data in this ex vivo human corneal study indicate that the biomechanical effect of CXL studied by resistance to enzymatic digestion in human corneas is comparable between irradiances of 9, 18 and 30 mW/cm and seems to be reduced at a fluence of 45 mW/cm2.

In recent years, increasingly sophisticated tools have allowed for more complex robotic surgery. Robotic gastrectomy, however, is adopted in only a few selected centers. The goals of this study were to examine the adoption of robotic gastrectomy and to compare outcomes between open and robotic gastric resections. This is a case-matched analysis of patients who underwent robotic and open gastric resection performed at Sanchinarro University Hospital, Madrid from November 2011 to February 2017. Patient data were obtained retrospectively. Clinicopathologic characteristics and perioperative and postoperative outcomes were recorded and analyzed. Two groups of demographically similar patients were analyzed: the robotic group (n = 20) and the open surgery group (n = 19). The patient characteristics of the two groups have been compared. Robotic resection resulted in less blood loss, shorter postoperative hospital stay, and a longer operating time. The two groups had similar complication rates. Pathological data were similar for both procedures. Robotic gastrectomy for locally advanced gastric carcinoma is safe, and long-term outcomes are comparable to those patients who underwent open resection. Robotic gastrectomy resulted in a shorter hospital stay, less blood loss and morbidity comparable with the outcomes of open gastrectomy.

Background The aim of the present study was to evaluate the effects of glucosamine-chondroitin sulphate combination on internal derangements of temporomandibular joint in clinical and biochemical manners. Material and Methods This randomized clinical study included 31 cases reporting joint tenderness, in which disc displacement was detected on MR imaging. In all patients, synovial fluid sampling was performed under local anesthesia. In the study group, the patients were prescribed a combination of 1500 mg glucosamine and 1200 mg chondroitin sulphate, while patients in the control group were only prescribed 50 mg tramadol HCl (twice daily) for pain control. After 8 weeks, synovial fluid sampling was repeated in the same manner. The levels of pain, maximum mouth opening (MMO), synovial fluid IL-1ß, IL-6, TNF-α and PGE2 measured before and after pharmacological intervention were compared. Results The reduction in pain levels was significant in both groups. There was no significant difference between two groups in terms of pain reduction. The improvement in MMO was significant in the study group but it was not in the control group. The MMO improvement was significantly higher in the study group compared to the control group. In the study group, significant decrease was observed in PGE2 level, while the decreases in IL-1β, IL-6 and TNF-α levels were not significant. In the control group, no significant decrease was observed in any of the inflammatory cytokines after 8 weeks, moreover IL-1ß and IL-6 levels were increased. Alterations of IL-1ß and IL-6 levels were significant in study group while TNF-α and PGE2 levels were not, compared to control group. Conclusions In conclusion, these results might suggest that glucosamine-chondroitin combination significantly increases the MMO and decreases the synovial fluid IL1β and IL6 levels in internal derangements of TMJ compared to tramadol. The modifications of synovial fluid TNF-α and PGE2 levels do not reach statistical significance. This combination also provides efficient pain relief in similar level with tramadol, a narcotic analgesic. Key words: Chondroitin sulphate, glucosamine, internal derangement, TMJ, tramadol.

2013-05-01

This systematic review aimed to establish the current knowledge about brain structure and executive function (EF) in children with cerebral palsy (CP). Five databases were searched (up till July 2012). Six articles met the inclusion criteria, all included structural brain imaging though no functional brain imaging. Study quality was assessed using the STROBE checklist. All articles scored between 58.7% and 70.5% for quality (100% is the maximum score). The included studies all reported poorer performance on EF tasks for children with CP compared to children without CP. For the selected EF measures non-significant effect sizes were found for the CP group compared to a semi-control group (children without cognitive deficits but not included in a control group). This could be due to the small sample sizes, group heterogeneity and lack of comparison of the CP group to typically developing children. The included studies did not consider specific brain areas associated with EF performance. To conclude, there is a paucity of brain imaging studies focused on EF in children with CP, especially of studies that include functional brain imaging. Outcomes of the present studies are difficult to compare as each study included different EF measures and cortical abnormality measures. Copyright © 2013 Elsevier Ltd. All rights reserved.

The etiology of gastric cancer is multifactorial. Marked differences in the incidence of gastric cancer among different ethnic groups living in the same geographical area have been observed. This study looked at ethnic and dietary factors in patients with gastric cancer diagnosed at a tertiary referral centre in Sikkim over a period of one year. Patients of 60 years and above were included in the study and divided into four ethnic groups : Bhutias, Lepchas, Rais and other groups. 211 cases underwent upper GI endoscopy and 32 were diagnosed to have gastric cancer. Gastric cancer incidence was highest in Bhutia ethnic group. A trend towards higher intake of smoked meats, fermented vegetables, salt tea, and H.pylori positivity in the Bhutia ethnic group was associated with higher incidence of gastric cancer as compared to other ethnic groups. The study with a referral centre bias showed that Bhutia ethnic group had a higher incidence of gastric cancer as compared to other ethnic groups.

The use of tranexamic acid in primary total knee replacement surgeries has been the subject of constant study. The strategies to reduce bleeding are aimed at reducing the need for blood transfusion due to the risks involved. In this study we evaluated the use of tranexamic acid in reducing bleeding, need for blood transfusion, and prevalence of postoperative deep vein thrombosis in primary total knee replacement. 62 patients undergoing primary total knee replacement were enrolled in the study, from June 2012 to May 2013, and randomized to receive a single dose of 2.5g of intravenous tranexamic acid (Group TA) or saline (Group GP), 5min before opening the pneumatic tourniquet, respectively. Hemoglobin, hematocrit, and blood loss were recorded 24h after surgery. Deep vein thrombosis was investigated during patient's hospitalization and 15 and 30 days after surgery in review visits. There was no demographic difference between groups. Group TA had 13.89% decreased hematocrit (p=0.925) compared to placebo. Group TA had a decrease of 12.28% (p=0.898) in hemoglobin compared to Group GP. Group TA had a mean decrease of 187.35mL in blood loss (25.32%) compared to group GP (p=0.027). The number of blood transfusions was higher in Group GP (p=0.078). Thromboembolic events were not seen in this study. Tranexamic acid reduced postoperative bleeding without promoting thromboembolic events. Copyright © 2015 Sociedade Brasileira de Anestesiologia. Published by Elsevier Editora Ltda.

Objectives: The aim of this in vitro study was to compare the efficacy of two retreatment rotary systems in the removal of Gutta-percha (GP) and sealer from the root canal walls with or without solvent. Materials and Methods: Forty-eight extracted human mandibular first premolars were prepared and obturated with GP and AH Plus sealer. Samples were then randomly divided into four groups. Group I was retreated with MtwoR rotary system without solvent, Group II was retreated with MtwoR rotary system with Endosolv R as the solvent, Group III with D-RaCe rotary system without solvent, and Group IV with D-RaCe rotary system and Endosolv R solvent. The cleanliness of canal walls was determined by stereomicroscope (×20) and AutoCAD software. Kruskal–Wallis test and Mann–Whitney U-test were used to compare the data. Results: Results showed that none of the retreatment systems used in this study was able to completely remove the root canal filling material. D-RaCe with or without solvent showed significantly (P > 0.05) less filling material at all levels compared to MtwoR with/without solvent. Conclusion: Within the limitation of the current study, D-RaCe rotary retreatment system is more effective in removing filling material from root canal walls when compared to MtwoR rotary retreatment system.

Introduction Carpal tunnel syndrome (CTS) is one of the most common entrapment neuropathies of the upper limbs. It results from compromised median nerve function of the wrist that is caused by increased pressure in the carpal tunnel. Repetitive use of the hand and wrist, obesity, pregnancy, rheumatoid diseases, trauma and endocrinopathies are some of the risk factors for CTS. Aim The purpose of this study was to find out whether patients with diabetes mellitus (DM), hypothyroidism and acromegaly have an increased incidence of carpal tunnel syndrome compared to each other and normal population. Materials and Methods Patients were assigned into three groups as follows: patients with type II DM n: 100, patients with hypothyroidism n:48 and patients with acromegaly n:36. In addition, 50 healthy individuals were included in the study as control subjects. Patients were asked if they had any pain, symptoms of paraesthesia and numbness. Patients with peripheral neuropathy were excluded from the study. Boston Symptom Severity Scale and Functional Capacity Scale were used to assess symptom severity and functional capacity. CTS was investigated by performing electrophysiological study for both hands. Results The incidence of CTS was significantly higher in all three groups compared to the control group (p>0.05). In addition, the incidence of CTS was significantly higher in the DM group compared to the hypothyroid and acromegaly groups (p<0.001). The incidence of bilateral CTS in the DM group was significantly higher compared to both hypothyroid and acromegaly groups and the control group (p<0.001). Conclusion CTS has a higher incidence in DM, hypothyroid and acromegaly patients compared to healthy individuals. Clinicians should be careful about development of CTS in DM, hypothyroidism and acromegaly. They should adopt a multidisciplinary approach and co-operate with the psychiatrist. PMID:26266148

Oral submucous fibrosis (OSF) is a chronic, insidious disease that is associated with significant functional morbidity and an increased risk for malignancy. Turmeric and its active ingredient "curcumin" are being studied upon as chemopreventive agents in various diseases. The present study aims to determine the efficacy of curcumin in the treatment of OSF. Thirty clinically diagnosed OSF patients were divided into two groups, 15 patients in each group from the Outpatient Department. Test group patients were treated with Longvida (curcumin) lozenges and control group with Tenovate ointment (clobetasol propionate (0.05%). The treatment was given for 3 months duration and follow-up was done for 6 months. Both the groups were advised for physiotherapy exercises by mouth exercise device. The baseline and follow-up results were compared for IIO (interincisal distance on maximum mouth opening), Visual Analogue Scale (VAS) for normal food and VAS for spicy food. The test group showed 5.93 (±2.37) mm increase in mouth opening compared to 2.66 (±1.76) mm of the control group. In relation to VAS scale with spicy and normal food the average reduction was 64 (42-73) and 77 (70.5-82) as compared to 34 (14.5-64.5) and 64 (46-75.5) respectively in control group. The test group results achieved in the treatment span was sustained in the follow-up (P < 0.05) compared to control group which showed statistically significant (P < 0.05) relapse. It can be concluded that combination strategies for the management of OSF which include the stoppage of causative ill habits, appropriate medicinal and physiotherapy management is more efficient than single therapeutic modality. It is evident from the study that curcumin holds good promise in the treatment of OSF in future.

Abstract Objective There has been a steady growth of chiropractic treatment using spinal manipulative therapy (SMT) that aims to increase the performance of athletes in various sports. This study evaluates the effect of SMT by chiropractors on the performance of golf players. Methods Golfers of 2 golf clubs in São Paulo, Brazil, participated in this study. They were randomized to 1 of 2 groups: Group I received a stretch program, and group II received a stretch program in addition to SMT. Participants in both groups performed the same standardized stretching program. Spinal manipulative therapy to dysfunctional spinal segments was performed on group II only. All golfers performed 3 full-swing maneuvers. Ball range was considered as the average distance for the 3 shots. Treatment was performed after the initial measurement, and the same maneuvers were performed afterward. Each participant repeated these procedures for a 4-week period. Student t test, Mann-Whitney nonparametric test, and 1-way analysis of variance for repeated measures with significance level of 5% were used to analyze the study. Results Forty-three golfers completed the protocol. Twenty participants were allocated to group I and 23 to group II. Average age, handicap, and initial swing were comparable. No improvement of full-swing performance was observed during the 4 sessions on group I (stretch only). An improvement was observed at the fourth session of group II (P = .005); when comparing the posttreatment, group II had statistical significance at all phases (P = .003). Conclusions Chiropractic SMT in association with muscle stretching may be associated with an improvement of full-swing performance when compared with muscle stretching alone. PMID:19948307

Purpose: To measure, quantify and compare Ocular Aberrations due to nuclear cataracts. Setting: Department of ophthalmology and school for ophthalmic technicians, college of medicine and health sciences, Sultan Qaboos University, Muscat, Oman. Design: Retrospective case controlled study. Methods: 113 eyes of 77 patients with nuclear cataract (NC) were recruited from outpatient clinic of a major tertiary referral center for Ophthalmology. Patients having NC with no co-existing ocular pathologies were selected. All patients were subjected to wavefront aberrometry (make) using Hartmann-Shack (HS) aberrometer. Consents were taken from all patients. Higher order Aberrations (HOA) were calculated with Zernike polynomials up to the fourth order. For comparison 28 eyes of 15 subjects with no lenticular opacities (control group) were recruited and evaluated in an identical manner. No pupillary mydriasis was done in both groups. Results: Total aberrations were almost six times higher in NC group compared to control (normal) subjects. The HOA were 21 times higher in NC group, and coma was significantly higher in NC eyes compared to normal (control) group. The pupillary diameter was significantly larger in control group (5.48mm ± 1.0024, p<.001) compared to NC (3.05mm ± 1.9145) subjects (probably due to younger control age group). Amongst Zernike coefficients up to fourth order, two polynomials, defocus (Z20) and spherical aberration (Z42) were found to be significantly greater amongst NC group, compared to normal control group. Conclusion: Nuclear cataracts predominantly produce increased defocus and spherical aberrations. This could explain visual symptoms like image deterioration in spite of normal Visual acuity.

This in vitro study is intended to compare the shear bond strength of recent self-etching primers to superficial, intermediate, and deep dentin levels. All teeth were sectioned at various levels and grouped randomly into two experimental groups and two control groups having three subgroups. The experimental groups consisted of two different dentin bonding system. The positive control group consisted of All Bond 2 and the negative control group was without the bonding agent. Finally, the specimens were subjected to shear bond strength study under Instron machine. The maximum shear bond strengths were noted at the time of fracture. The results were statistically analyzed. Comparing the shear bond strength values, All Bond 2 (Group III) demonstrated fairly higher bond strength values at different levels of dentin. Generally comparing All Bond 2 with the other two experimental groups revealed highly significant statistical results. In the present investigation with the fourth generation, higher mean shear bond strength values were recorded compared with the self-etching primers. When intermediate dentin shear bond strength was compared with deep dentin shear bond strength statistically significant results were found with Clearfil Liner Bond 2V, All Bond 2 and the negative control. There was a statistically significant difference in shear bond strength values both with self-etching primers and control groups (fourth generation bonding system and without bonding system) at superficial, intermediate, and deep dentin. There was a significant fall in bond strength values as one reaches deeper levels of dentin from superficial to intermediate to deep.

The aim of this study was to explore the effect of electroacupuncture (EA) on immune function in patients undergoing supratentorial craniotomy. We also examined whether point specificity in EA was present. The study involved 29 patients undergoing craniotomy. The patients were divided into three groups: a control (C, n=10), an EA (A, n=9) and a sham acupoints group (S, n=10). Blood samples were collected at the following time points: before anesthesia (T0), 4 h after the induction of anesthesia (T1), 1 day post-surgery (T2) and 2 days post-surgery (T3) to determine the levels of tumor necrosis factor-α (TNF-α), interleukin-8 (IL-8), interleukin-10 (IL-10), immunoglobulin M (IgM), IgA and IgG. Data were analyzed using SPSS 13.0 software. When comparing the levels of cytokines following surgery, we observed that the peripheral blood IL-8 levels in groups A and S were increased significantly compared with those of group C at 1 and 2 days after surgery. When comparing immunoglobulin levels after surgery, we established that the peripheral blood IgA levels in group C had decreased significantly compared to those of group A and group S 4 h after induction of anesthesia and 1 day after surgery. However, there was no significant difference between group A and group S. Compared with simple general anesthesia, acupuncture combined with anesthesia partially reduces immune suppression in the perioperative periods under the same conditions as the simple general anesthesia. Point specificity in EA was not present. PMID:24137250

The purpose of this study was to compare the marginal and internal adaptation of cobalt-chromium (Co-Cr) copings fabricated from conventional wax pattern, three-dimensional (3D)-printed resin pattern, and laser sintering technique. A total of thirty copings were made, out of which ten copings were made from 3D-printed resin pattern (Group A), ten from inlay wax pattern (Group B), and ten copings were obtained from direct metal laser sintering (DMLS) technique (Group C). All the thirty samples were seated on their respective dies and sectioned carefully using a laser jet cutter and were evaluated for marginal and internal gaps at the predetermined areas using a stereomicroscope. The values were then analyzed using one-way ANOVA test and post hoc Bonferroni test. One-way ANOVA showed lowest mean marginal discrepancy for DMLS and highest value for copings fabricated from inlay wax. The values for internal discrepancy were highest for DMLS (169.38) and lowest for 3D-printed resin pattern fabricated copings (133.87). Post hoc Bonferroni test for both marginal and internal discrepancies showed nonsignificant difference when Group A was compared to Group B ( P > 0.05) and significant when Group A was compared with Group C ( P < 0.05). Group B showed significant difference ( P < 0.05) when compared with Group C. Marginal and internal discrepancies of all the three casting techniques were within clinically acceptable values. Marginal fit of DMLS was superior as compared to other two techniques, whereas when internal fit was evaluated, conventional technique showed the best internal fit.

To compare the effects of levosimendan with milrinone in cardiac surgical patients with pulmonary hypertension and left ventricular dysfunction. A prospective, randomized study. Tertiary care teaching hospital. The study included patients with valvular heart disease and pulmonary artery hypertension undergoing valve surgery. Forty patients were allocated randomly to receive either milrinone, 50 µg/kg bolus followed by infusion at a rate of 0.5 µg/kg/min (group 1), or levosimendan, 10 µg/kg bolus followed by infusion at a rate of 0.1 µg/kg/min (group 2) for 24 hours after surgery. Hemodynamic parameters were measured using a pulmonary artery catheter, and biventricular functions were assessed using echocardiography. Mean pulmonary artery pressures and the pulmonary vascular resistance index were comparable between the 2 groups at several time points in the intensive care unit. Biventricular function was comparable between both groups. Postcardiopulmonary bypass right ventricular systolic and diastolic functions decreased in both groups compared with baseline, whereas 6 hours postbypass left ventricular ejection fraction improved in patients with stenotic valvular lesions. Levosimendan use was associated with higher heart rate, increased cardiac index, decreased systemic vascular resistance index, and increased requirement of norepinephrine infusion compared with milrinone. The results of this study demonstrated that levosimendan was not clinically better than milrinone. Levosimendan therapy resulted in a greater increase in heart rate, decrease in systemic vascular resistance, and a greater need for norepinephrine than in patients who received milrinone.

The objective of this study was to determine the effect of a home-based exercise program on fatigue, anxiety, quality of life (QoL), and immune function of thyroid cancer patients taking thyroid hormone replacement after thyroidectomy. This quasi-experimental study with a non-equivalent control group included 43 outpatients taking thyroid hormone replacement after thyroidectomy (22 in the experimental group and 21 in the control group). After education about the home-based exercise program, subjects in the experimental group underwent 12 weeks of aerobic, resistance, and flexibility exercise. A comparative analysis was conducted between the two groups. Patients in the experimental group were significantly less fatigued or anxious (p < 0.01). They reported significantly improved QoL (p < 0.05) compared to those in the control group. Natural killer cell activity was significantly higher in the exercise group compared to that in the control group (p < 0.05). A home-based exercise program is effective in reducing fatigue and anxiety, improving QoL, and increasing immune function in patients taking thyroid hormone replacement after thyroidectomy. Therefore, such a home-based exercise program can be used as an intervention for patients who are taking thyroid hormone replacement after thyroidectomy.

Traditional monitoring of blood pressure in hypertensive pregnant women requires frequent visits to the maternity outpatient services. Home blood-pressure monitoring (HBPM) could offer a cost-saving alternative that is acceptable to patients. The main objective of this study was to undertake a health economic analysis of HBPM compared with traditional monitoring in hypertensive pregnant women. This was a case-control study. Cases were pregnant women with hypertension who had HBPM with or without the adjunct of a smartphone app, via a specially designed pathway. The control group were managed as per existing hospital guidelines. Specific outcome measures were the number of outpatient visits, inpatient bed stays and investigations performed. Maternal, fetal and neonatal adverse outcomes were also recorded. Health economic analysis was performed using two methods: direct cost comparison of the study dataset and process scenario modelling. There were 108 women in the HBPM group, of whom 29 recorded their results on the smartphone app (App-HBPM) and 79 in their notes (Non-app HBPM). The control group comprised of 58 patients. There were significantly more women with chronic hypertension in the HBPM group (49.1% vs 25.9%, P = 0.004). The HBPM group had significantly longer duration of monitoring (9 weeks vs 5 weeks P = 0.004) and started monitoring from an earlier gestation (30 weeks vs 33.6 weeks, P = 0.001). Despite these differences, the mean saving per week for HBPM compared with the control group was £200.69. For the App-HBPM cohort, the saving per week compared with the control group was £286.53. The process modelling method predicted savings of between £98.32 and £245.80 per week using HBPM compared to the traditional monitoring. HBPM in hypertensive pregnancies appears to be cost-saving compared with traditional monitoring, without compromising maternal, fetal or neonatal safety. Larger studies are required to confirm these findings. This article is protected by copyright. All rights reserved.

Breast cancer continues to be the most commonly diagnosed cancer in women globally. Early detection, diagnosis and treatment of breast cancer are key to better outcomes. Since many women will discover a breast cancer symptom themselves, it is important that they are breast cancer aware i.e. have the knowledge, skills and confidence to detect breast changes and present promptly to a healthcare professional. To assess the effectiveness of interventions for raising breast cancer awareness in women. We searched the Cochrane Breast Cancer Group's Specialised Register (searched 25 January 2016), Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 12) in the Cochrane Library (searched 27 January 2016), MEDLINE OvidSP (2008 to 27 January 2016), Embase (Embase.com, 2008 to 27 January 2016), the World Health Organization's International Clinical Trials Registry Platform (ICTRP) search portal and ClinicalTrials.gov (searched 27 Feburary 2016). We also searched the reference lists of identified articles and reviews and the grey literature for conference proceedings and published abstracts. No language restriction was applied. Randomised controlled trials (RCTs) focusing on interventions for raising women's breast cancer awareness i.e. knowledge of potential breast cancer symptoms/changes and the confidence to look at and feel their breasts, using any means of delivery, i.e. one-to-one/group/mass media campaign(s). Two authors selected studies, independently extracted data and assessed risk of bias. We reported the odds ratio (OR) and 95% confidence intervals (CIs) for dichotomous outcomes and mean difference (MD) and standard deviation (SD) for continuous outcomes. Since it was not possible to combine data from included studies due to their heterogeneity, we present a narrative synthesis. We assessed the quality of evidence using GRADE methods. We included two RCTs involving 997 women: one RCT (867 women) randomised women to receive either a written booklet and usual care (intervention group 1), a written booklet and usual care plus a verbal interaction with a radiographer or research psychologist (intervention group 2) or usual care (control group); and the second RCT (130 women) randomised women to either an educational programme (three sessions of 60 to 90 minutes) or no intervention (control group). Knowledge of breast cancer symptomsIn the first study, knowledge of non-lump symptoms increased in intervention group 1 compared to the control group at two years postintervention, but not significantly (OR 1.1, 95% CI 0.7 to 1.6; P = 0.66; 449 women; moderate-quality evidence). Similarly, at two years postintervention, knowledge of symptoms increased in the intervention group 2 compared to the control group but not significantly (OR 1.4, 95% CI 0.9 to 2.1; P = 0.11; 434 women; moderate-quality evidence). In the second study, women's awareness of breast cancer symptoms had increased one month post intervention in the educational group (MD 3.45, SD 5.11; 65 women; low-quality evidence) compared to the control group (MD -0.68, SD 5.93; 65 women; P < 0.001), where there was a decrease in awareness. Knowledge of age-related riskIn the first study, women's knowledge of age-related risk of breast cancer increased, but not significantly, in intervention group 1 compared to control at two years postintervention (OR 1.8; 95% CI 0.9 to 3.5; P < 0.08; 447 women; moderate-quality evidence). Women's knowledge of risk increased significantly in intervention group 2 compared to control at two years postintervention (OR 4.8, 95% CI 2.6 to 9.0; P < 0.001; 431 women; moderate-quality evidence). In the second study, women's perceived susceptibility (how at risk they considered themselves) to breast cancer had increased significantly one month post intervention in the educational group (MD 1.31, SD 3.57; 65 women; low-quality evidence) compared to the control group (MD -0.55, SD 3.31; 65 women; P = 0.005), where a decrease in perceived susceptibility was noted. Frequency of Breast CheckingIn the first study, no significant change was noted for intervention group 1 compared to control at two years postintervention (OR 1.1, 95% CI 0.8 to 1.6; P = 0.54; 457 women; moderate-quality evidence). Monthly breast checking increased, but not significantly, in intervention group 2 compared to control at two years postintervention (OR 1.3, 95% CI 0.9 to 1.9; P = 0.14; 445 women; moderate-quality evidence). In the second study, women's breast cancer preventive behaviours increased significantly one month post intervention in the educational group (MD 1.21, SD 2.54; 65 women; low-quality evidence) compared to the control group (MD 0.15, SD 2.94; 65 women; P < 0.045). Breast Cancer AwarenessWomen's overall breast cancer awareness did not change in intervention group 1 compared to control at two years postintervention (OR 1.8, 95% CI 0.6 to 5.30; P = 0.32; 435 women; moderate-quality evidence) while overall awareness increased in the intervention group 2 compared to control at two years postintervention (OR 8.1, 95% CI 2.7 to 25.0; P < 0.001; 420 women; moderate-quality evidence). In the second study, there was a significant increase in scores on the Health Belief Model (that included the constructs of awareness and perceived susceptibility) at one month postintervention in the educational group (mean 1.21, SD 2.54; 65 women) compared to the control group (mean 0.15, SD 2.94; 65 women; P = 0.045).Neither study reported outcomes relating to motivation to check their breasts, confidence to seek help, time from breast symptom discovery to presentation to a healthcare professional, intentions to seek help, quality of life, adverse effects of the interventions, stages of breast cancer, survival estimates or breast cancer mortality rates. Based on the results of two RCTs, a brief intervention has the potential to increase women's breast cancer awareness. However, findings of this review should be interpreted with caution, as GRADE assessment identified moderate-quality evidence in only one of the two studies reviewed. In addition, the included trials were heterogeneous in terms of the interventions, population studied and outcomes measured. Therefore, current evidence cannot be generalised to the wider context. Further studies including larger samples, validated outcome measures and longitudinal approaches are warranted.

Lateral ankle sprain is one of the most common injuries. Since the structural and pathological differences in mechanical ankle instability (MAI) and functional ankle instability (FAI) may not be the same, it may be better to treat these as separate groups. The purpose of this study was to compare the difference in postural sway between MAI and FAI in patients with chronic ankle instability (CAI). Twenty-six patients with CAI and 14 healthy control participants were included in the study. The CAI patients were subdivided into MAI (15 patients) and FAI (11 patients) groups. Patients who were diagnosed with lateral ankle ligaments rupture by magnetic resonance imaging and ultrasonography were assigned to the MAI group. All participants performed single-limb postural sway tests 3 times on each leg with eyes closed and open. The average distances from the mean center of pressure position in the mediolateral and anteroposterior directions were recorded and compared among the 3 groups. The unstable ankles in the MAI group showed significantly greater postural sway in the anterior, posterior, and medial directions compared with those in the control group with eyes closed. With eyes open, significantly greater postural sway was found in the anterior direction. In the FAI group, no difference was found in postural sway compared with those in the control group. The MAI group showed significantly greater postural sway in the anterior direction compared with the FAI group with eyes closed and open. No significant difference in postural sway was found between the unstable and stable ankles in the MAI or FAI groups, with or without vision. Patients with MAI have deficits in postural control, especially in anterior-posterior directions. However, no difference was found in postural sway in patients with FAI compared with healthy people. As MAI patients suffer from deficits in postural control, balance training should be applied in those patients. In addition, special training should also include the contralateral side after a unilateral ankle ligament injured. © The Author(s) 2014.

This study aimed to estimate the effects of a health mentoring program on fasting blood sugar, total cholesterol, triglyceride, physical activity, self care behavior and social support changes among community-dwelling vulnerable elderly individuals with diabetes. A non-equivalent control group pre-post-test design was used. Participants were 70 community-dwelling vulnerable elderly individuals with diabetes. They were assigned to the experimental (n=30) or comparative (n=30) or control group (n=28). The experimental group participated in the health mentoring program, while the comparative group participated in health education program, the control group did not participate in any program. Data analyses involved a chi-square test, Fisher's exact test, a generalized linear model, and the Bonferroni correction, using SPSS 23.0. Compared to the control group, the experimental and comparative groups showed a significant decrease in fasting blood sugar, total cholesterol, and triglyceride. Compared to the comparative and control groups, the experimental group showed significant improvement in self care behavior. However, there were no statistical differences in physical activity or social support among the three groups. These findings indicate that the health mentoring program is an effective intervention for community-dwelling vulnerable elderly individuals with diabetes. This program can be used as an efficient strategy for diabetes self-management within this population. © 2018 Korean Society of Nursing Science.

Lead is found in small but appreciable quantities in air, soil, drinking water, and food. Exposure to such amounts of lead does not lead to acute lead toxicity but produces subtle effects particularly in children. The aim of this study was to investigate the effects of blood lead level on biochemical and hematological parameters in children with neurological diseases in Western Maharashtra, India, and to estimate the blood lead level by liver and kidney function tests and hematological parameters in children with neurological disorders admitted to the pediatric ward and compare them with healthy controls. In this study, 30 children with various neurological disorders admitted to the pediatric ward of Smt. Kashibai Navale Medical College and General Hospital, Pune, Maharashtra, India, were compared with 30 age- and sex-matched healthy controls. Four milliliters of venous blood was collected for estimation of blood lead level, and biochemical and hematological parameters were determined using standard methods. Blood lead level was significantly increased in the study group (p<0.01, 65.38%) compared to that in the control group. When different neurological conditions were grouped into three groups according to blood lead levels, there was a significant difference between the groups. All other biochemical and hematological parameters were not significantly altered in the study group as compared to the control group. Neurologically challenged children are more vulnerable to lead intoxication. It is imperative for the parents to take extra care of their children's food habits and limit hand-to-mouth activities to prevent lead intoxication.

Traffic policemen working in the busy traffic signal areas get exposed to the vehicular emissions for years together. The fumes, chemicals and particles present in the emission are reported to be damaging to the lung functions of these individuals. Since there were no data available on the PFT parameters of traffic police personnel of Pondicherry, this study was taken up to assess the effect of traffic air pollution on their pulmonary functions. PFT parameters were recorded in age- and BMI-matched 30 traffic police personnel (study group) and 30 general police personnel (control group) of male gender. As chronic smoking is known to be a critical factor in altering lung function, PFT parameters were compared between the smokers as well as nonsmokers of both the groups. In nonsmokers, there was significant decrease in VC (P < 0.05), FEV1 (P < 0.01), FEF-25 (P < 0.05) and PIF (P < 0.05) in study group compared to the control group. In smokers, there was significant decrease in VC (P < 0.05), FEV1 (P <00001), PEF (P < 0.0001), MVV (P < 0.0001), FEF-25 (P < 0.0001), and PIF (P < 0.01) in study group compared to the control group. These changes indicate restriction to the lung expansion, obstruction and narrowing of the airways in traffic police personnel compared to the general police personnel. This may be due to exposure to vehicular pollution for several hours in a day for many years causing decreased functional capacity of the lungs and chronic smoking worsens the condition.

Prostate cancer is one of the most common cancers in the elderly population. The standard treatment is radical prostatectomy (RARP). However, urologists do not have consents on the postoperative urine drainage management (suprapubic tube (ST)/ urethral catheter (UC)). Thus, we try to compare ST drainage to UC drainage after robot-assisted radical prostatectomy regarding to comfort, recovery rate and continence using the method of meta-analysis. A systematic search was performed in Dec. 2017 on PubMed, Medline, Embase and Cochrane Library databases. The authors independently reviewed the records to identify studies comparing ST with UC of patients underwent RARP. Meta-analysis was performed using the extracted data from the selected studies. Seven studies, including 3 RCTs, with a total of 946 patients met the inclusion criteria and were included in our meta-analysis. Though there was no significant difference between the ST group and the UC group on postoperative pain (RR1.73, P 0.20), our study showed a significant improvement on bother or discomfort, defined as trouble in hygiene and sleep, caused by catheter when compared two groups at postoperative day (POD) 7 in ST group (RR2.05, P 0.006). There was no significant difference between the ST group and UC group on urinary continence (RR0.98, P 0.74) and emergency department visit (RR0.61, P 0.11). The rates of bladder neck contracture and other complications were very low in both groups. Compared to UC, ST showed a weak advantage. So it might be a good choice to choose ST over RARP.

The purpose of the present study was to carry out a comparative histological analysis of the endometrium in postmenopausal women who made use of phytoestrogens in order to assess the efficacy and possible side effects of this therapy. This study was carried out by forming 2 groups in order to compare the results. One group was given a dietary supplement of phytoestrogens for 24 months, whereas the other was given a placebo for the same period of time. At the beginning of this study endometrial bioptical samples were taken from those patients who had been previously selected at our University Centre. This study was started only with those postmenopausal patients whose bioptical sample was histologically suitable, and it was neither hyperplastic, nor cancerous and nor secretive. During these 24 months there have been frequent contacts aimed at verifying the standard therapeutic behaviour, symptoms and appearance of side effects. At the end of the study new and final bioptical samples of endometrium were taken from both groups. One-hundred and forty-one patients completed the study. Five patients (3.4%) who were submitted to phytoestrogens therapy showed a weak proliferative endometrium bioptical sample. All the other biopsies at the beginning and at the end of the study showed an atrophic and inactive sample. Hot flushes, night sweats, vaginal dryness and dyspareunia improved at the end of the study for the group treated with phytoestrogens as compared to the one treated with a placebo. Although there have not been very significant differences ias to symptoms and side effects, it was noted that insomnia was the most common symptom in the group treated with non-hormonal therapy based on phytoestrogens. Phytoestrogens did not cause any sensitive and worrisome stimulation of the endometrial mucosa. Insomnia was more frequent in the group treated pharmacologically in the 24 months of the study, whereas hot flushes, night sweats, vaginal dryness and dyspareunia persisted or increased as compared to the beginning of the study in the group treated with a placebo, but this did not occur for the group treated with phytoestrogens.

In previous studies, toothpastes with high levels of sodium bicarbonate (>50%) have reduced gingival inflammation and oral malodour. This study compared the effects of brushing for 6 weeks with 67% (test group) or 0% (control group) sodium bicarbonate toothpaste on gingival health. This was a single-centre, single examiner-blind, randomized, controlled, two-treatment, parallel-group study. Eligible subjects (≥18 years) had ≥20 gradable teeth, mild-to-moderate gingivitis, a positive response to bleeding on brushing and ≥20 bleeding sites. The primary objective was to compare the number of bleeding sites following twice-daily use of 67% sodium bicarbonate toothpaste or 0% sodium bicarbonate toothpaste after 6 weeks. Secondary endpoints included Modified Gingival Index (MGI), Bleeding Index (BI) and volatile sulphur compounds (VSC), assessed after 6 weeks. Safety was assessed by treatment-emergent oral soft tissue abnormalities and adverse events. Of 148 patients randomized (74 to each treatment), 66 (89.2%) completed the study in the test group, compared with 69 (93.2%) in the control group. Compared with the control group, the test group had a significant reduction in the number of bleeding sites at Week 6 (absolute difference - 11.0 [-14.0, -8.0], P < 0.0001; relative difference - 25.4%), together with significant reductions in MGI and BI (both P < 0.0001). Although the median reductions from baseline for VSC were numerically greater in the test group, the difference did not reach statistical significance (P = 0.9701). This 67% sodium bicarbonate toothpaste provided statistically significant improvements in gingival health and bleeding after 6 weeks of use. © 2016 The Authors.

The aim of our study was to investigate the link between MTHFR gene C677T polymorphism and DNMTs levels in patients with Subclinical Hypothyroidism (SCH). In this study 19 adult patients with subclinical hypothyroidism and 19 healthy controls (mean age 31±5.5 and 33±5.1 years respectively) were recruited. All patients were diagnosed based on serum levels of TSH, FT4, anti-TG and anti-TPO antibodies. Written informed consents were obtained from all study subjects. Genomic DNA was extracted using Quick-DNA Universal Kit (Zymo Research, USA). The MTHFR C677T polymorphism was genotyped by PCR-RFLP method. Levels of DNMT1 and 3a were measured in nuclear extracts of PBMC using DNMTs assay kits (Abcam). Our data indicates that the frequency of genotypes and alleles were different among the patient and the control group. There is a significant increase in CC genotype distribution in the control group when compared to the SCH patient group, while the CT as well as TT genotype distribution were not increased significantly in SCH group versus control group. However the C allele is significantly prevalent in the control group compared to the SCH group, while T allele is prevalent in patients compared to the control group with a statically significant difference. In addition, individuals with TT and CT genotypes and hypothyroidism showed elevated amount of DNMT3a in nuclear extracts of PBMC compared with controls, while no significant difference in DNMT1 levels was observed. This study indicates the MTHFR C677T variant may contribute in alteration of epigenetic regulation such as DNA methylation mediated by DNA methyltransferases in patients with subclinical hypothyroidism and also, carriers of the T allele might have an increasing risk of developing SCH.

Background & Objectives: Periodontal disease is characterized by the presence of gingival inflammation, periodontal pocket formation, loss of connective tissue attachment and alveolar bone around the affected tooth. Different modalities have been employed in the treatment and regeneration of periodontal defects which include the use of bone grafts, PRP and other growth factors.The purpose of this prospective, randomized controlled study was to compare the regenerative efficacy of PRP and bonegraft in intrabony periodontal defects. Methodology: This randomized control trial was carried out in the Department of Periodontics & Oral Implantology, Kalinga Institute of Dental Sciences and Hospital, KIIT University, Bhubaneswar. The study sample included 20 periodontal infrabony defects in 20 patients, 12 males and 8 females. The patients were aged between 25 -45 years(with mean age of 35 years). The 20 sites selected for the study were was randomly divided into 2 groups of 10 sites each. Group A: PRP alone, Group B: Bone Graft. Statistical Anaysis & Results: Statistical Analysis Was Done Using SPSS (Version 18.0): Statistical analysis was done usingpaired ‘t’ tests and ANOVA that revealed a significant reduction ingingival index, plaque index, probing pocket depth and gain in clinical attachment level at various time intervalswithin both the groups. Radiographic evaluation revealed statistically significant defect fill (p<0.001) at the end of 6months within both the groups. However, there was astatistically significant difference seen in group B radiographically, when compared to group A. Conclusion: Both the groups showed promising results in enhancing periodontal regeneration; however the resultswith bonegraftwere comparatively better, although not statistically significant when compared to PRP alone.

Thalassemias are a heterogeneous group of genetic disorders characterized by hypochromic microcytic anemia that caused by deficient synthesis of one or more of globin subunits of human hemoglobin. This study has been conducted in the Northern part of Iraq among 238 subjects having β-thalassemia major (BTM). To evaluate their oral health status, dentofacial anomalies of patients who attended the Thalassemic center in Erbil city, were compared to 258 subjects of a control group according to the criteria suggested by the WHO in 1997, which is used to assess permanent teeth. Only 8.51% of the total study group demonstrated crowding of anterior teeth in one or both segments compared to the control group. Spacing in the incisal segments was higher, namely 19.23% in BTM compared to13.6% in the control group with a statistically significant difference (p<0.05). A higher percentage of both study and control groups were having an overbite grade (0.3-5.0 mm) of 49.59%, and 56.81%, respectively. It was found that the distal deviation from the normal anteroposterior molar relation in BTM was higher compared to the control group. Nearly similar percentages of patients were found to have an over jet grade(0.0-3.5 mm). Values of plaque and gingival health indices were recorded to be higher among the study group (plaque index = 1.570, ∓0.321 and gingival index = 1.205, ∓0.308). Differences were statistically highly significant for all indices (p<0.01). This may indicate that there is a negative attitude and poor dental knowledge of thalassemic subjects and their parents toward proper oral hygiene and dental health.

Scar retraction due to exposed bone in palatoplasty is the leading cause of constricted maxilla. Modern techniques have focused on minimizing the effects of scarring by reducing the exposure of the bone area. The objective of the study was to compare the palatal mucoperiosteal detachment with minimal lateral incision, followed by their synthesis, with the maintenance of lateral areas for relaxation (similar to the von Langenbeck technique) and evaluate the transversal development of the maxilla. A prospective, randomized study was conducted, in which the molding of the dental arch of 14 pigs in 2 stages (at 1 month and 5 months) was performed. The pigs were divided into 3 groups: group 1 underwent lateral incision of the palate for mucoperiosteal detachment and maintenance of bone exposure; group 2 underwent mucoperiosteal palatal detachment with lateral access and no bone exposure; and group 3, the control animals, did not undergo any surgical procedures. Measurements of the dental arches were compared between the groups to assess differences in the development of the maxillary transverse diameter. There were no animals lost during the study. Group 1 showed greater growth restriction of the transverse diameter of the maxilla (36%) when compared with groups 2 (56%) and 3 (59%). Groups 2 and 3 showed similar transverse maxillary development, with no statistical difference. The technique of mucoperiosteal detachment without lateral relief incision has the advantage of reducing future morbidity of a constricted maxilla. This study demonstrated that the technique described can reduce rates of maxillary underdevelopment, a significant complication inherent in the procedure for palatoplasty. The lateral incisions reduce maxillary growth by approximately 20% as compared with this technique. Level II of evidence.

The purpose of this study was to compare perceived stress in general, stress due to pregnancy, and post partum complications between a group of unmarried adolescent first-time mothers and a group of married adolescent first-time mothers. Never-pregnant adolescents served as a comparison group on perceived stress. Health outcomes of infants of the two groups of adolescent mothers were also compared on birth weight, nutritional status (weight gain) and immunization status. The study design was non-experimental, comparative and descriptive. A convenience sample of dyads of 64 unmarried adolescent mothers and their infants, 64 married adolescents and their infants, and 64 high school students participated in this study. Data were collected in 3 hospitals, 2 health centres (clinics) and a high school in Lesotho. The differences between the three groups of adolescents in perceived stress, were determined using ANOVA. The t-test was used to determine the differences between the group of unmarried adolescent mothers and the group of married mothers on stress due to pregnancy. The difference in postpartum complications between these two groups of adolescent mothers was determined using Chi-square. The t-test was also used to determine differences in birth weight, nutritional status and immunization status between the group of infants of unmarried mothers and infants of married mothers. Findings of this study revealed significant differences in perceived stress between both groups of adolescent mothers and the group of never pregnant adolescents (p < .0001). The Chaffe' test revealed that never pregnant adolescents had lowest levels of perceived stress than both groups of adolescent mothers (p < .0001). Both groups of adolescent mothers had high levels of stress due to pregnancy and the difference between the two groups was non-significant. No differences were observed between infant health outcomes of unmarried mothers and infants of married mothers. The infants of both groups were generally healthy and the majority of them had appropriate type and doses of immunizations six weeks post birth. Adolescent mothers in the low lands of Lesotho perceive pregnancy to be a stressful event despite marriage. Therefore adolescents should be discourage from early childbirth. Policy makers need to come up with gender sensitive policies that will make it easier for girls who get pregnant to continue with their education, so that they may be productive and self-reliant.

Previous studies have indicated a correlation between indication for cholecystectomy and long-term gastrointestinal quality-of-life (QoL). The aim of the present study was to compare QoL in a post-cholecystectomy cohort with the background population and with historical controls. A post-cholecystectomy study group (on average 4 years after cholecystectomy) was compared with a control group from the background population using the Gastrointestinal Quality-of-Life Index (GIQLI). EQ-5D scores were compared with expected scores derived from recent historical data. The post-cholecystectomy study group (N = 451) had better QoL measured by the EQ-5D compared with historical controls (p < 0.001), similar total GIQLI scores as the control group (N = 390), but scored worse on the GIQLI gastrointestinal symptoms subscale score (p < 0.001). The results include an item-by-item breakdown of the GIQLI questionnaire where the scores for diarrhea, bowel urgency, bloating, regurgitation, abdominal pain, flatus, fullness, nausea, uncontrolled stools, belching, heartburn, restricted eating, and bowel frequency were found to be significantly lower (i.e. worse) in the post-cholecystectomy cohort than in the control group. The opposite was true for relationships, endurance, sexual life, physical strength, feeling fit, not being frustrated by illness, and being able to carry out leisure activities, i.e. items related to general performance and well-being. In this study, QoL after cholecystectomy was good, but there was an increased prevalence of gastrointestinal symptoms compared to the background population.

Introduction: Microleakage continues to be a main reason for failure of root canal treatment where the challenge has been to achieve an adequate seal between the internal structure and the main obturating material. The objective of this study is to compare the sealing ability of 3 newer obturating materials GuttaFlow, Resilon/Epiphany system (RES) and Thermafil, using silver nitrate dye and observing under stereomicroscope. Methodology: Thirty single rooted teeth were divided into following groups. Group I : GuttaFlow ;Group II : Resilon /Epiphany sealer Group III : Thermafil with AH-Plus sealer. Teeth were decoronated and instrumented with profile rotary system and obturated with specified materials. Apical seal was determined by dye penetration method using silver nitrate. Then the specimens were transversely sectioned at each mm till 3 mm from the apex. Dye leakage was determined using stereomicroscope. Statistical analysis of the results was performed using Kruskall-Wallis test. Results: The results showed that Group II i.e., Resilon with Epiphany sealer showed the least amount of microleakage when compared to Group I i.e., GuttaFlow and Group III i.e., Thermafil with AH-plus sealer. Conclusion: Based on the results of this study it can be concluded that RES had higher sealing ability followed by Thermafil and GuttaFlow in vitro but further studies have to be carried out to make a direct correlation between these results and invivo situation.

Amisulpride, an atypical antipsychotic was evaluated for antidepressant like activity in forced swimming test in Swiss albino mice. The effect of amisulpride was compared with that of fluoxetine, the standard antidepressant and olanzapine, another atypical antipsychotic claimed to have antidepressant like activity. Both acute and chronic studies were carried out. In both the studies, animals were divided into four groups (n = 8 each) and subjected to oral drug interventions as follows -- Group 1- control (distilled water, 1 mL/kg); Group 2- fluoxetine in a dose of 10 mg/kg 23.5, 5 and 1 h before the test; Group 3-amisulpride in a dose of 70 mg/kg 23.5, 5 and 1 h before the test; Group 4- olanzapine in a dose of 2 mg/kg 23.5, 5 and 1 h before the study. In the chronic study, the treatment was given daily for 28 days with last dose being given 2 h prior to the test. A time sampling method was used to score the behavioral activity in each group. Results of both the studies indicated that animals given amisulpride displayed significant improvement in swimming behavior (p < 0.01), while markedly reducing immobility as compared to control group (p <0.01). Fluoxetine also showed significant difference in activity as compared to amisulpride and olanzapine (p < 0.01). There was no statistically significant difference between amisulpride and olanzapine in terms of effect on immobility and swimming phases in albino mice (p > 0.05). We conclude that amisulpride per se has an antidepressant like activity comparable to that of olanzapine though the activity was significantly less than that of fluoxetine.

The objective of this study was to test the effect of sugar-free chewing gum sweetened with xylitol or maltitol compared to the use of a gum base or no gum on gingivitis and plaque scores under both brushing and non-brushing circumstances. The design of the study was a four-group, double-blinded, randomized controlled study with a 3-week duration. In each group, the participants did not brush the teeth in the lower jaw designated to develop experimental gingivitis, while maintaining normal oral hygiene procedures in the upper jaw. After professional dental prophylaxis, the participants were allocated into one of four groups (xylitol, maltitol, gum base or no gum). Chewing gum was used five times a day for 10 min. 220 participants completed the study and provided evaluable data. The increase in bleeding on marginal probing (BOMP) and plaque scores (PS) in the non-brushed (lower) jaw with experimental gingivitis was significant in all groups (P < 0.001). As compared to the gum base, the increase in BOMP in the xylitol and maltitol group was significantly lower. In the brushed upper jaw, no significant changes for BOMP were observed from the baseline to the end point of the study, and there were no significant differences in BOMP and PS between the groups. In circumstances where regular brushing is performed, no effect of chewing gum was observed on bleeding and plaque scores. In the absence of brushing, chewing xylitol or maltitol gum provided a significant inhibitory effect on gingivitis scores compared to chewing gum base. The difference when compared to the group not using gum was not significant. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Retrospective radiographic analysis. To determine which lumbar interbody technique is most effective for restoring lordosis, increasing disk height, and reducing spondylolisthesis. Lumbar interbody fusions are performed in hopes of increasing fusion potential, correcting deformity, and indirectly decompressing nerve roots. No published study has directly compared anterior, lateral, and transforaminal lumber interbody fusions in terms of ability to restore lordosis, increase disk height, and reduce spondylolisthesis. Lumbar interbody fusion techniques were retrospectively compared in terms of improvement of lordosis, disk height, and spondylolisthesis between preoperative and follow-up lateral radiographs. A total of 220 consecutive patients with 309 operative levels were compared by surgery type: anterior (184 levels), lateral (86 levels), and transforaminal (39 levels). Average follow-up was 19.2 months (range, 1-56 mo), with no statistical difference between the groups. Intragroup analysis showed that the anterior (4.5 degrees) and lateral (2.2 degrees) groups significantly improved lordosis from preoperative to follow-up, whereas the transforaminal (0.8 degrees) group did not. Intergroup analysis showed that the anterior group significantly improved lordosis more than both the lateral and transforaminal groups. The anterior (2.2 mm) and lateral (2.0 mm) groups both significantly improved disk height more than the transforaminal (0.5 mm) group. All 3 groups significantly reduced spondylolisthesis, with no difference between the groups. After lumbar interbody fusion, improvement of lordosis was significant for both the anterior and lateral groups, but not the transforaminal group. Intergroup analysis showed the anterior group had significantly improved lordosis compared to both the other groups. The anterior and lateral groups had significantly increased disk height compared to the transforaminal group. All the 3 groups significantly reduced spondylolisthesis, with no difference between the groups.

The objective of this retrospective study was to compare biological and technical complications of implant-supported and tooth-implant-supported double crown-retained dentures (DCRDs) with those of tooth-supported DCRDs. Sixty-three DCRDs were monitored. One study group included 16 prostheses with a combination of implants and natural teeth as double crowns (ti group), whereas in the second study group, 19 dentures were retained exclusively on implants (ii group); a third study group with 28 exclusively tooth-supported dentures served as controls (tt group). Tooth loss, implant failure, and technical complications (loss of retention of primary crown, abutment screw loosening, loss of facing, fracture of resin denture teeth and fracture of saddle resin) were analysed. During the observation period of 24 months, no implants or teeth were lost in the ti group and three technical complications were recorded. In the ii group, two implants were lost, two cases of peri-implantitis occurred and four technical complications were observed. In the tt group, two cases of tooth loss and seven technical complications were observed. At the time of the last examination, all prostheses of the ti group and the ii group were functional. Patients of these two study groups reported high satisfaction with both function and aesthetics with no significant difference between the two groups. Treatment with DCRDs showed comparable results in the three study groups. The 2-year results indicate that double crowns can be recommended for implant and combined tooth-implant-retained dentures.

The establishment of the ECTS (European Credit Transfer System) is one of the pillars of the European Space of Higher Education. This way of accounting for the time spent in training has two essential parts, classroom teaching (work with the professor) and distance learning (work without the professor, whether in an individual or collective way). Much has been published on the distance learning part, but less on the classroom teaching section. In this work, the authors investigate didactic strategies and associated aids for distance learning work in a concept based on flipped classroom where transmitting information is carried out with aids that the professor prepares, so that the student works in an independent way before the classes, thus being able to dedicate the classroom teaching time to more complex learning and being able to count on the professor's help. Three teaching aids applied to the study of anatomy have been compared: Notes with images, videos, and augmented reality. Four dimensions have been compared: the time spent, the acquired learnings, the metacognitive perception, and the prospects of the use of augmented reality for study. The results show the effectiveness, in all aspects, of augmented reality when compared with the rest of aids. The questionnaire assessed the acquired knowledge through a course exam, where 5.60 points were obtained for the notes group, 6.54 for the video group, and 7.19 for the augmented reality group. That is 0.94 more points for the video group compared with the notes and 1.59 more points for the augmented reality group compared with the notes group. This research demonstrates that, although technology has not been sufficiently developed for education, it is expected that it can be improved in both the autonomous work of the student and the academic training of health science students and that we can teach how to learn. Moreover, one can see how the grades of the students who studied with augmented reality are more grouped and that there is less dispersion in the marks compared with other materials.

Percutaneous nephrolithotomy (PCNL) is done under general anaesthesia in most of the centres. Associated complications and cost are higher for general anaesthesia than for regional anaesthesia. Present study is designed to compare the efficacy of epidural block versus spinal anaesthesia with regards to intraoperative mean arterial pressure, heart rate, postoperative pain intensity, analgesic requirement, Postoperative complications and patient satisfaction in patients undergoing PCNL. After taking Ethical Committee clearance, patients were randomly allocated into 2 groups using table of randomization (n= 40 each) Group E- Epidural block, Group S- Spinal block. Various parameters like intraoperative mean arterial pressure, heart rate, postoperative pain intensity, analgesic requirement, postoperative complications and patient satisfaction were studied in these groups. Quantitative data was analysed using unpaired t-test and qualitative data was analysed using chi-square test. Twenty four times in Epidural as compared to fifteen times in spinal anaesthesia two or more attempts required. Mean time (min) required to achieve the block of anaesthesia in group E and group S was 15.45±2.8 and 8.52±2.62 min respectively. Mean arterial pressure (MAP) at 5 min, 10 min and 15 min were significantly lower in spinal group as compared to epidural group. After 30 minutes, differences were not significant but still MAP was lower in spinal group. After 30 minutes difference in heart rate between two groups was statistically significant and higher rate recorded in spinal group till the end of 3 hours. Postoperative VAS score was significantly higher in spinal group and 4 hours onwards difference was highly significant. Postoperative Nausea Vomiting (PONV) Score was significantly higher in spinal group as compared to epidural group. For PCNL, segmental epidural block is better than spinal anaesthesia in terms of haemodynamic stability, postoperative analgesia, patient satisfaction and reduced incidence of PONV. Epidural anaesthesia is difficult to execute and takes longer time to act as compared to spinal block which limits its use.

Flatfoot deformity is a lever arm disease that incurs kinetic inefficiency during gait. The purpose of this study was to measure the degree of kinetic inefficiency by comparing the gait analysis data of a flatfoot group with a normal control group. The patient group consisted of 26 children (21 males and 5 females) with symptomatic flatfoot. They were examined with gait analysis between May 2005 and February 2014. Exclusion criteria were patients with secondary flatfoot caused by neuromuscular disorders, tarsal coalition, vertical talus, or others. Patients' mean age was 9.5 years (range, 7 to 13 years). The gait analysis data of the study group and the normal control group were compared. The mean vertical ground reaction force (GRF) in the push-off phase was 0.99 for the patient group and 1.15 for the control group ( p < 0.05). The mean ankle moment in the sagittal plane during the push-off phase was 0.89 for the patient group and 1.27 for the control group ( p < 0.05). The mean ankle power in the sagittal plane during the push-off phase was 1.38 for the patient group and 2.52 for the control group ( p < 0.05). The aforementioned results show that patients with pes planovalgus had a reduction of moment, power, and GRF in the push-off phase during gait. Symptomatic flatfeet had a moment inefficiency of 30% and power inefficiency of 45% during gait compared to feet with preserved medial longitudinal arches.

Metatarsus adductus (MA) is a common pediatric foot deformity. Current recommendations suggest observation until 4-6 months, then casting if the deformity persists. Based on our review of the literatures, no randomized controlled trial has been conducted to study the effectiveness of parental stretching in the correction of MA in newborn. Ninety-four newborn feet that were diagnosed as MA by clinical examination were enrolled. Feet were randomized into two groups: observation group and stretching group. Outcome measurements were performed to compare success rate between groups. According to Pearson's χ 2 test, there were no statistically significant differences between groups with regard to the overall success of the parental stretching program ( p = 0.191). There was also no significant difference between groups for mild degree or moderate-to-severe degree ( p = 0.134, p = 0.274, respectively). A more rapid success rate was observed in the stretching group at the first month follow-up, but rate of improvement then decreased. The stretching group tended to have a lower success rate compared to the observation group in moderate-to-severe feet, but the difference was not statistically significant. Parental stretching program found no benefit over observation group in this study. Parental stretching program should not be applied for newborn babies with moderate-to-severe MA as the result from the study appeared to have lower success rate compared to observation group. Observe until 4-6 months, then corrective casting for the persisting deformity is recommended.

The purpose of this study was to compare differences in the time when bowel sounds were heard and gas was passed in women who had an abdominal hysterectomy and were treated for 5 minutes (experimental group A) or 10 minutes (experimental group B) with San-Yin-Jiao (SP-6) acupressure. The design of this study was a nonequivalent control group non-synchronized post test only design. The participants included 142 women, 39 in experimental group A, 30 in experimental group B, and 73 in the control group. Data was collected using a structured questionnaire which included items on general characteristics and a self report of time when gas was passed. Differences for the three groups as to time when bowel sounds were heard and gas was passed were analyzed using ANOVA. The time when bowel sounds were heard was statistically significantly shorter in both experimental groups compared to the control group(F=10.29, p=.000). The time when gas was passed was statistically significantly shorter in experimental group B(10 min) compared to the control group(F=4.68, p=.011). It could be concluded that SP-6 acupressure of 10 minutes was effective in shortening the time until bowel sounds were heard and gas was passed for women who had had an abdominal hysterectomy. Replication of the study with a larger number of participants is necessary in order to be able to generalize the results.

This study compared outcomes of transurethral enucleation with bipolar (TUEB) with transurethral resection in saline (TURis). Thirty patients who underwent TURis were compared with 30 who underwent TUEB. Perioperative treatment outcomes, preoperative and 1-month postoperative International Prostrate Symptom Scores (IPSS), quality of life (QOL) index, maximum flow rate, average urinary flow, post- void residual urinary volume, and complications were compared. There were no significant differences in IPSS, measurements of urinary flow, or duration of catheterization. However, the improvement of QOL index after surgery was significantly greater in the TUEB group than the TURis group. The TUEB group had significantly longer surgical time, but tended to have greater enucleated tissue weight than the TURis group. There was no significant difference in enucleated tissue weight per unit time between the groups. The TUEB group also tended to have less hemoglobin decrease at postoperative day 1; this tendency was more prominent in patients with an estimated prostate volume of ≥ 50 ml. No significant differences in postoperative complications were observed. This study confirmed that the previously reported safety and efficacy of TUEB are comparable to those of TURis. TUEB appears especially safe for those with a large benign hypertrophic prostate.

The aim of the study was to evaluate the macular pigment optical density (MPOD) levels in patients with wet age-related macular degeneration (AMD), dry AMD, and also in healthy controls. This study was conducted at Department of Ophthalmology, and the study design was a prospective study. Forty-eight patients with wet AMD, 51 patients with dry AMD, and 50 controls were included in the study. All patients were naive to both previous lutein or zeaxanthin administration and any previous intravitreal injections. Fundus reflectance (VISUCAM 500, reflectance of a single 460 nm wavelength) was used to measure the MPOD levels. Three groups were compared regarding age, gender, serum lutein, and zeaxanthin concentrations as well as MPOD levels. Serum lutein and zeaxanthin levels were significantly higher in control group when compared with wet AMD (Group 1) and dry AMD (Group 2) (P = 0.001 and P< 0.001, respectively). Mean MPOD was found to be similar in all of the three study subgroups (P = 0.630). However, maximum MPOD was significantly higher in control group when compared with Group 1 and 2 (P = 0.003). There was no correlation between serum lutein or zeaxanthin concentrations and mean MPOD levels (P = 0.815, r = 0.014 and P = 0.461, r = 0.043, respectively), but there was a weak correlation between serum zeaxanthin concentration and maximum MPOD level (P = 0.042, r = 0.124). Maximum MPOD level was found to be correlated with the level of AMD (Group 1, 2, and 3; r = 0.184, P = 0.041). Maximum MPOD level was found to be lower in patients with AMD when compared with control cases. Mean MPOD and maximum MPOD levels were similar in wet and dry AMD Groups. These results can be applied clinically keeping in mind that MPOD measurements with one wavelength reflectometry may not be completely reliable.

Cerebral palsy is the most common cause of physical disability in childhood. Spasticity is a significant contributor to the secondary impairments impacting functional performance and participation. The most common lower limb spasticity management is focal intramuscular injections of Botulinum Toxin-Type A accompanied by individually-delivered (one on one) physiotherapy rehabilitation. With increasing emphasis on improving goal-directed functional activity and participation within a family-centred framework, it is timely to explore whether physiotherapy provided in a group could achieve comparable outcomes, encouraging providers to offer flexible models of physiotherapy delivery. This study aims to compare individual to group-based physiotherapy following intramuscular Botulinum Toxin-A injections to the lower limbs for ambulant children with cerebral palsy aged four to fourteen years. An assessor-masked, block randomised comparison trial will be conducted with random allocation to either group-based or individual physiotherapy. A sample size of 30 (15 in each study arm) will be recruited. Both groups will receive six hours of direct therapy following Botulinum Toxin-A injections in either an individual or group format with additional home programme activities (three exercises to be performed three times a week). Study groups will be compared at baseline (T1), then at 10 weeks (T2, efficacy) and 26 weeks (T3, retention) post Botulinum Toxin-A injections. Primary outcomes will be caregiver/s perception of and satisfaction with their child's occupational performance goals (Canadian Occupational Performance Measure) and quality of gait (Edinburgh Visual Gait Score) with a range of secondary outcomes across domains of the International Classification of Disability, Functioning and Health. This paper outlines the study protocol including theoretical basis, study hypotheses and outcome measures for this assessor-masked, randomised comparison trial comparing group versus individual models of physiotherapy following intramuscular injections of Botulinum Toxin-A to the lower limbs for ambulant children with cerebral palsy.

Introduction. The management of obstructive sleep apnea (OSA) in patients who cannot afford a continuous positive airway pressure (CPAP) device is challenging. In this study we compare time to CPAP procurement in three groups of patients diagnosed with OSA: uninsured subsidized by a humanitarian grant (Group 1), uninsured unsubsidized (Group 2), and those with Medicare or Medicaid (Group 3). We evaluate follow-up and adherence in Group 1. We hypothesize that additional factors, rather than just the ability to obtain CPAP, may uniquely affect follow-up and adherence in uninsured patients. Methods. 30 patients were in Groups 1 and 2, respectively. 12 patients were in Group 3. Time of CPAP procurement from OSA diagnosis to CPAP initiation was assessed in all groups. CPAP adherence data was collected for Group 1 patients at 1, 3, 6, and 9 months. Results. There were no significant differences between groups in gender, age, body mass index, or apnea hypopnea index. The mean time to procurement in Group 1 was shorter compared to Group 2 but not significant. Compared to both Group 1 and Group 2, Group 3 patients had significantly shorter times to device procurement. Conclusion. Time to procurement of CPAP was significantly shorter in those with Medicaid/Medicare insurance compared to the uninsured.

Cultural differences in the experience of everyday symptoms: a comparative study of South Asian and European American women.

This paper describes a study of medically ambiguous symptoms in two contrasting cultural groups. The study combined a qualitative, meaning-centered approach with a structured coding system and comparative design. Thirty-six South Asian immigrants and thirty-seven European Americans participated in a semistructured health history interview designed to elicit conceptual models of medically unexplained illness. The groups reported similar symptoms, but the organization of illness episodes and explanatory models associated with these episodes differed sharply. A variety of cultural variables and processes is proposed to account for observed differences, including somatization, the role of local illness categories, and the divergent core conflicts and values associated with gender roles. It is argued that the comparative design of the study provided insights that could not have been achieved through the study of a single group.

The impact of chronic hepatitis B on the clinical outcome of acute hepatitis A remains controversial. The aim of present study was to evaluate the clinical characteristics of acute hepatitis A in cases with underlying chronic hepatitis B compared to cases of acute hepatitis A alone. Data on 758 patients with acute hepatitis A admitted at two university-affiliated hospitals were reviewed. Patients were classified into three groups: group A, patients with both acute hepatitis A and underlying chronic hepatitis B (n = 27); group B, patients infected by acute hepatitis A alone whose sexes and ages were matched with patients in group A (n  = 54); and group C, patients with acute hepatitis A alone (n = 731). None of the demographic features of group A were significantly different from those of group B or C, except for the proportion of males and body weight, which differed from group C. When comparing to group B, clinical symptoms were more frequent, and higher total bilirubin and lower albumin levels were observed in group A. When comparing to group C, the albumin levels were lower in group A. There were no differences in the duration of hospital stay, occurrence of acute kidney injury, acute liver failure, prolonged cholestasis, or relapsing hepatitis. This study revealed that clinical symptoms and laboratory findings were less favorable for patients with acute hepatitis A and chronic hepatitis B compared to those with acute hepatitis A alone. However, there were no differences in fatal outcomes or serious complications. Copyright © 2012 Wiley Periodicals, Inc.

Willingness of Emerging Adults to Engage in Consensual Non-Monogamy: A Mixed-Methods Analysis.

PubMed

Sizemore, Kayla M; Olmstead, Spencer B

2018-07-01

Over the past decade, research on consensual non-monogamy (CNM) has increased. However, willingness to engage in CNM is an understudied phenomenon within this field. Because qualitative methods are rarely used to study this phenomenon, little is known about why individuals may or may not be willing to engage in CNM. Further, research on CNM has devoted little attention to the period of emerging adulthood. The current study used a mixed-methods approach to examine a sample of emerging adults' (ages 18-29; N = 549) willingness to engage in CNM. Results from a qualitative content analysis revealed three distinct groups (Unwilling, Willing, and Open-Minded), and several subthemes emerged within each group that help explain why emerging adults are willing to engage in CNM. Quantitative analyses examined the relationship between group membership and demographic characteristics, finding that a greater proportion of women and heterosexual participants were Unwilling. Results also indicated that a greater proportion of men were Willing, and a greater proportion of sexual minorities were Open-Minded. Group mean differences were examined using quantitative measures of CNM attitudes and willingness. The Unwilling group reported more negative attitudes towards CNM compared to the Open-Minded and Willing groups. Additionally, the Open-Minded group reported more negative attitudes compared to the Willing group. On the willingness to engage in CNM Scale, the Unwilling group had lower mean scores compared to the Willing and Open-Minded groups. The Willing group had higher mean scores compared to the Open-Minded group. Implications for CNM research and methodology are discussed.

Hypothermic perfusion (HP) of the liver is applied during total vascular exclusion (TVE) to reduce ischemic injury during liver resection. No studies have been performed comparing different perfusion solutions for HP. The aim of this experimental study was to compare Ringer-lactate solution (RL) with Celsior solution (Cs) for HP in a pig model of 60-min TVE. Twenty pigs underwent 60-min TVE of the liver. Groups were TVE without HP (no-HP, n = 9), TVE with HP using RL (n = 6), and TVE with HP using Cs (n = 5). Blood and liver tissue samples were taken before TVE and during 24-h reperfusion. In the no-HP group, plasma aspartate aminotransferase values were significantly increased during reperfusion (p < 0.05), while liver tissue pO(2) levels (p < 0.01) were decreased when compared to the HP groups. After 24-h reperfusion, bile production and liver tissue glutathione content were significantly higher (p < 0.05) in the Cs group (42.0 +/- 1.7 mL/h and 44.9 +/- 2.2 nmol/mg, respectively) as compared to the RL group (31.5 +/- 3.5 mL/h and 19.6 +/- 1.8 nmol/mg, respectively). The protective effect of HP during TVE was confirmed in this study. HP with Cs was more effective in reducing ischemic injury as compared to HP with RL.

Objective The purpose of this study was to evaluate the effect of a cycle ergometer exercise program on exercise capacity and inspiratory muscle function in hospitalized patients with heart failure awaiting heart transplantation with intravenous inotropic support. Methods Patients awaiting heart transplantation were randomized and allocated prospectively into two groups: 1) Control Group (n=11) - conventional protocol; and 2) Intervention Group (n=7) - stationary cycle ergometer exercise training. Functional capacity was measured by the six-minute walk test and inspiratory muscle strength assessed by manovacuometry before and after the exercise protocols. Results Both groups demonstrated an increase in six-minute walk test distance after the experimental procedure compared to baseline; however, only the intervention group had a significant increase (P=0.08 and P=0.001 for the control and intervention groups, respectively). Intergroup comparison revealed a greater increase in the intervention group compared to the control (P<0.001). Regarding the inspiratory muscle strength evaluation, the intragroup analysis demonstrated increased strength after the protocols compared to baseline for both groups; statistical significance was only demonstrated for the intervention group, though (P=0.22 and P<0.01, respectively). Intergroup comparison showed a significant increase in the intervention group compared to the control (P<0.01). Conclusion Stationary cycle ergometer exercise training shows positive results on exercise capacity and inspiratory muscle strength in patients with heart failure awaiting cardiac transplantation while on intravenous inotropic support.

Hawthorn extract consumption is becoming more widespread among the Jordanian population with cardiovascular disorders. We conducted this prospective observational longitudinal study to determine the impact of hawthorn extract on bleeding risk in patients who undergo cardiac surgery. A prospective observational study was performed on 116 patients who underwent cardiac surgery in the period between June 2014 and May 2015. Patients were divided into two groups: Group I (patients recently consumed hawthorn extract) and Group II (patients never consumed hawthorn extract). Endpoint measures included the rates of reopening to control bleeding, early mortality, duration of intensive care unit stay, total in-hospital stay period, and duration and amount of chest tube drainage. Hawthorn patients had a significantly higher rate of postoperative bleeding necessitating take back to the operating room compared to the control group (10% versus 1%; P = .03) respectively. The overall mortality rate for group I and II was 4% and 0% respectively; P = .17. Chest tubes were kept in for longer times in group I compared to group II (54 ± 14.6 versus 49 ± 14.7 hours respectively; P = .01). Group I stayed longer in the intensive care unit compared to group II (24 versus 22 hours respectively; P = .01). The total in-hospital stay period was comparable between the two groups. Hawthorn extract consumption does increase the potential for bleeding and the amount of chest tube output after cardiac surgery.

The aim of this study was evaluate the effect of HBO on diabetic rats. Twenty rats were distributed into four groups (n = 5): Control (C); Control + HBO (CH); Diabetes (D) and Diabetes + HBO (DH). Diabetes was induced by streptozotocin, and bone defects were created in both femurs in all animals. HBO therapy began immediately after surgery and was performed daily in the CH and DH groups. After 7 days, the animals were euthanized. The femurs were removed, demineralized, embedded in paraffin, and histologic images were analyzed. Qualitative histologic analyses showed more advanced stage bone regeneration in control groups (C and CH) compared with diabetic groups (D and DH). Histomorphometric analysis showed significantly increased bone neoformation in CH compared with the other groups (p < 0.001). Diabetic Group (D) showed decreased bone neoformation compared with non-diabetic groups (C and CH) (p < 0.001); however DH did not differ from C Group (p > 0.05). The mast cell population increased in CH compared with the other groups (C, D, and DH) (p < 0.05). The mast cell population did not differ between D and DH Groups. This study showed that HBO therapy improved early bone regeneration in diabetic rats and increased the mast cell population only in non-diabetic animals. HBO was shown to be important treatment for minimizing deleterious effects of diabetes on bone regeneration.

There has been no study reporting on the influence of sleep deprivation on the male reproductive system including sperm quality. In this study, we hypothesized that sleep deprivation could lead to adverse effect on the male reproductive system. The rats were divided into three groups: 1) control (home-cage, n = 10); 2) SD4 (sleep deprivation for 4 days, n = 10); and 3) SD7 (sleep deprivation for 7 days, n = 10). Sleep deprivation was performed by a modified multiple platform method. Sperm quality (sperm motion parameters and counts), hormone levels (corticosterone and testosterone), and the histopathology of testis were evaluated and compared between the three groups. A statistically significant reduction (P = 0.018) was observed in sperm motility in the SD7 group compared to those of the control group. However, there were no significant differences in other sperm motion parameters, or in sperm counts of the testis and cauda epididymis between three groups. Compared with the control group, the SD4 (P = 0.033) and SD7 (P = 0.002) groups exhibited significant increases of corticosterone levels, but significant decreases of testosterone levels were found in the SD4 (P = 0.001) and SD7 (P < 0.001) groups. Seminiferous tubular atrophy and/or spermatid retention was partially observed in the SD4 and SD7 groups, compared with the normal histopathology of the control group. Sleep deprivation may have an adverse effect on the male reproductive system in rats.

Prior studies have suggested that inhibited temperament may be associated with an increased risk for developing anxiety or mood disorder, including bipolar disorder. However, the neurobiological basis for this increased risk is unknown. The aim of this study was to examine temperament in symptomatic and asymptomatic child offspring of parents with bipolar disorder (OBD) and to investigate whether inhibited temperament is associated with aberrant hippocampal volumes compared with healthy control (HC) youth. The OBD group consisted of 45 youth, 24 of whom had current psychiatric symptoms (OBD + s) and 21 without any psychiatric symptoms (OBD - s), and were compared with 24 HC youth. Temperament characteristics were measured by using the Revised Dimensions of Temperament Survey. Magnetic resonance imaging was used to measure hippocampal volumes. The association between temperament and hippocampal volumes was tested by using multiple regression analysis. Compared with the OBD - s group, the OBD + s group had significantly more inhibited temperament traits, less flexibility, more negative mood, and less regular rhythm in their daily routines. In contrast, the OBD - s group was more likely to approach novel situations compared with OBD + s or HC groups. Within the OBD + s group, a more inhibited temperament was associated with smaller right hippocampal volumes. In this study, symptomatic OBD were characterized by an inhibited temperament that was inversely correlated with hippocampal volume. Additional longitudinal studies are needed to determine whether inverse correlations between hippocampal volume and inhibited temperament represent early markers of risk for later developing bipolar disorder.

This study aims to study the efficacy of simultaneous endoscopic bladder neck incision (BNI) and primary endoscopic valve incision (PEVI) in patients with posterior urethral valves (PUV). Nine PUV patients underwent PEVI and BNI over a year. They were compared to nine comparable historical controls that had undergone only PEVI. Trends in renal function tests, urodynamics and changes in the upper urinary tracts were evaluated after 3 months during which no pharmacotherapy was given. The incidence of bladder dysfunction in the two groups was similar-55.5 % in case group and 66.6 % in control group. Hypocompliant, high-pressure bladder was the predominant cystometric finding in both groups. Three patients in the case group and two patients in the control group had high end infusion pressure (EIP) with poor compliance. Detrusor overactivity (DOA) was seen in 23.1 % patients in the case group as compared to 55.5 % patients in the control group (P = 0.3348). Five patients in both groups were later started on anticholinergics due to raised EIP, small capacity bladder and/or DOA. Although BNI should theoretically improve the outcome of PUV patients, the current pilot study failed to demonstrate any significant difference. A larger sample size and longer follow-up are required to prove or disprove its efficacy.

The purpose of the study was to compare hip agonist-antagonist isometric strength ratios between females with patellofemoral pain (PFP) syndrome and pain-free control group. One hundred and twenty females between 15 and 40 years of age (control group: n = 60; PFP group: n = 60) participated in the study. Hip adductor, abductor, medial rotator, lateral rotator, flexor, and extensor isometric strength were measured using a hand-held dynamometer. Comparisons in the hip adductor/abductor and medial/lateral rotator and flexor/extensor strength ratios were made between groups using independent t-tests. Group comparisons also were made between the anteromedial hip complex (adductor, medial rotator, and flexor musculature) and posterolateral hip complex (abductor, lateral rotator, and extensor musculature). On average, the hip adductor/abductor isometric strength ratio in the PFP group was 23% higher when compared with the control group (p = 0.01). The anteromedial/posterolateral complex ratio also was significantly higher in the PFP group (average 8%; p = 0.04). No significant group differences were found for the medial/lateral rotator ratio and flexor/extensor strength ratios. The results of this study demonstrate that females with PFP have altered hip strength ratios when compared with asymptomatic controls. These strength imbalances may explain the tendency of females with PFP to demonstrate kinematic tendencies that increase loading on the patellofemoral joint (i.e., dynamic knee valgus).

Paget's disease of bone (PDB) may lead to hearing loss. The present study was conducted with the aim of measuring, characterizing and determining the risk factors for hearing loss in a group of subjects with PDB. An observational, transversal, case-control study was conducted, a cohort of 76 subjects diagnosed with PDB in the case group and a control group of 134 subjects were included. Clinical, demographic and audiometric data were analysed. The comparative analysis between the subjects in the PDB group and the control group found that the case group showed higher hearing thresholds (39,51dB) compared with the control group (37.28dB) (P=.069) and presented a greater rate of conductive hearing loss (22.76%) than the control group (12.05%) (P=.0062). The study of risk factors for hearing loss found that skull involvement in bone scintigraphy, age and high blood pressure were risk factors for higher impairment in PDB. The subjects with PDB showed more profound and a higher proportion of conductive hearing loss than the control group. The patients with PDB and skull involvement presented a more severe hearing loss compared with the subjects without skull involvement. Skull involvement and age were found to be risk factors for hearing loss. Copyright © 2018 Sociedad Española de Otorrinolaringología y Cirugía de Cabeza y Cuello.

Purpose To assess the effect of extracorporeal shock wave therapy (ESWT) for healthy participants with hamstring tightness. Materials and Methods This study was performed at a university rehabilitation hospital. Twenty nine healthy adults with hamstring tightness were enrolled and randomly allocated into four groups (ESWT, stretching exercise, ESWT with stretching exercise, and control). The effects of individual treatments were compared by the finger-to-floor test and popliteal angle. Results The ESWT group, stretching exercise group and ESWT with stretching exercise group had decreased finger-to-floor distances and right popliteal angles immediately after intervention, compared with the control group (p<0.05). At 4 weeks after completion of the interventions, finger-to-floor distances and the right popliteal angle in only the ESWT with stretching exercise group showed a significant improvement, compared with the control group (p=0.008 and 0.023). Conclusion While ESWT and stretching both reduced hamstring tightness immediately after interventions, only ESWT with stretching exercise maintained the significantly improved relief of hamstring tightness significantly after 4 weeks.

Hemophilic arthropathy due to recurrent joint bleeding leads to physical, psychological and socioeconomic problems in children with hemophilia and reduces their quality of life. The purpose of this study was to evaluate joint damage through various parameters and to determine functional deterioration in the musculoskeletal system during walking using kinetic and kinematic gait analysis. Physical examination and kinetic and kinematic gait analysis findings of 19 hemophilic patients aged 7-20 years were compared with those of age, sex and leg length matched controls. Stride time was longer in the hemophilia group (p=0.001) compared to the age matched healthy control group, while hip, knee and ankle joint rotation angles were more limited (p=0.001, p=0.035 and p=0.001, respectively). In the hemophilia group, the extensor moment of the knee joint in the stance phase was less than that in the control group (p=0.001). Stride time was longer in the severe hemophilia group compared to the mild-moderate hemophilia and control groups (p=0.011 and p=0.001, respectively). Rotation angle of the ankle was wider in the control group compared to the other two groups (p=0.001 for both). Rotation angle of the ankle joint was narrower in the severe hemophilia group compared to the others (p=0.001 for each). Extensor moment of the knee joint was greater in the control group compared to the other two groups (p=0.003 and p=0.001, respectively). Walking velocity was higher in the control group compared to the severe hemophilia group. Kinetic and kinematic gait analysis has the sensitivity to detect minimal changes in biomechanical parameters. Gait analysis can be used as a reliable method to detect early joint damage.

The aim of this clinical study was to evaluate and compare the desensitizing effects of a gallium?aluminum?arsenide (GaAlAs) laser and sodium fluoride (NaF) varnish on dentine hypersensitivity (DH) in periodontal maintenance patients. The use of lasers opens a new dimension in the treatment of DH. Forty-eight patients with 244 teeth affected by DH were included in the trial. To be included in the study, the subjects had to have 4 or more hypersensitive teeth at different quadrants. Selected teeth were randomly assigned to a GaAlAs laser group, placebo laser group, NaF varnish group, or a placebo NaF varnish group. Laser therapy was performed at 8.5?J/cm(2) energy density. In the placebo laser group, the same laser without laser emission was used. In the NaF varnish group, the varnish was painted at the cervical region of the teeth. In the placebo NaF varnish group, the same treatment procedures were performed with a saline solution. DH was assessed with a visual analog scale (VAS); immediately, at 1 week, and at 1, 3, and 6 months after treatments. Intra-group time-dependent data were analyzed by Friedman's test, and Wilcoxon's rank sum test was used to evaluate the differences within groups. GaAlAs laser and NaF varnish treatments resulted in a significant reduction in the VAS scores immediately after treatments that were maintained throughout the study when compared to the baseline and placebo treatments. In the NaF group, there was a significant increase in the VAS scores at 3 and 6 months compared to at 1 week and 1 month. The placebo treatments showed no significant changes in VAS scores throughout the study period. Within the limits of the study, GaAlAs laser irradiation was effective in the treatment of DH, and it is a more comfortable and faster procedure than traditional DH treatment.

Ebselen is used as a drug in clinical trials against stroke, reperfusion injury with anti-atherosclerotic and renoprotective effects. The aim of this study is to investigate the protective effect of ebselen, on torsion/detorsion (T/D)-induced biochemical and histopathological changes in experimental testicular ischaemia/reperfusion injury. A total of 28 male Wistar Albino rats were divided into four groups: group 1(sham-operated group, n = 7), group 2(ebselen group, n = 7), group 3(torsion/detorsion + saline, n = 7) and group 4(T/D + 10 mg kg(-1) ebselen group, n = 7). The tissue homogenate samples were used for immediate nitric oxide (NO), malondialdehyde (MDA), superoxide dismutase, catalase and glutathione measurement. Testes in all groups were evaluated for the biochemical assay and histopathological examinations. To evaluate spermatogenesis, Johnsen scoring system was used. Testicular tissue MDA and NO levels in group 3 were significantly higher than in group 1 and 4. In histological evaluation of the testicular tissues, ebselen administration improved tubular histology significantly compared with T/D group. Significant increase in histological score was observed in the testis of group 3 compared with group 1 and 2. Histological score in group 4 significantly decreased compared with group 3. Johnson score was significantly lower in T/D group compared with all other three groups, ebselen administration increased the score significantly compared with T/D group. Ebselen reduced oxidative biochemical and histopathological damage in our testicular T/D rat model. © 2013 Blackwell Verlag GmbH.

The aim of the study was to analyse body composition of preterm infants fed with either breast milk or formula compared to a control group of full-term newborns. Fifty-three newborns were enrolled: a group of 34 very low birth weight (VLBW) preterm newborns subdivided into a formula-fed (n = 23; group A) and breast milk-fed (n = 11; group B) group, and a control group of 19 full-term infants (group C). Their body composition was assessed by a bioelectrical impedance analysis (BIA) either at the estimated time of birth in the VLBW group or during the 1st week of life in the full-term group. There was no difference in body weight or length between any of the three studied groups. However, we discovered that fat free mass (% FFM) was lower (83.5% vs. 85.5%; p < 0.01), while fat mass (% FM) was higher (16.4% vs.14.5%; p < 0.01) in group A compared to full-term newborns. There were no such differences in FFM (84.3% vs. 85.5%; p = 0.13) or FM (15.7% vs. 14.5%; p = 0.13) between group B and control. To sum up, the VLBW infants fed with breast milk shared similar body composition with the full-term infants, while the formula-fed VLBW developed higher amounts of adipose tissue and lower amounts of fat-free mass. This is the first study to expose differences in fat tissue content attributed to type of provided nutrition, which has become significant as early as estimated time of birth despite the comparable weight.

This fMRI study investigated mental simulation of state/psychological and action verbs during adolescence. Sixteen healthy subjects silently read verbs describing a motor scene or not (STIMULUS: motor, state/psychological verbs) and they were explicitly asked to imagine the situation or they performed letter detection preventing them from using simulation (TASK: imagery vs. letter detection). A significant task by stimuli interaction showed that imagery of state/psychological verbs, as compared to action stimuli (controlled by the letter detection) selectively increased activation in the right supramarginal gyrus/rolandic operculum and in the right insula, and decreased activation in the right intraparietal sulcus. We compared these data to those from a group of older participants (Tomasino et al. 2014a). Activation in the left supramarginal gyrus decreased for the latter group (as compared to the present group) for imagery of state/psychological verbs. By contrast, activation in the right superior frontal gyrus decreased for the former group (as compared to the older group) for imagery of state/psychological verbs. Copyright © 2018 Elsevier Inc.

Alteration in peripheral iron indices has been reported in a number of movement disorders, particularly Parkinson's disease. We hypothesized that iron stores may be diminished in children at an early stage of tic disorder. Using data retrieved from electronic medical records, we compared serum ferritin levels, an indicator of body iron store balance, in drug-naive children diagnosed for the first time with tic disorder (study group; N = 47, 32 boys/15 girls, aged 8.66 ± 3.17 years) compared to age- and sex-matched children with headaches (comparison group, n = 100, 62 boys/38 girls, aged 9.51 ± 3.15 years) treated in the same pediatric neurological clinic. Mean serum ferritin levels were significantly lower (-32%, p = 0.01) in the tic disorder group compared to the headache group. No significant differences were detected in circulatory hemoglobin, iron, transferrin, and platelet count between the two groups. Our findings suggest that body iron stores may be reduced in children with recent-onset tic disorder.

The current study investigated differences in decision-making style and risk-taking between financial traders, non-trading bank employees, and people not working in finance. Traders scored significantly higher than participants in the other two groups on the cognitive reflection test (CRT) which measures the tendency to inhibit automatic but frequently false responses in reasoning tasks. Scores for traders compared to people outside the banking sector were also higher on a self-rated scale for reflective thinking in decision-making, but there were no differences in self-rated intuitive thinking between groups. Financial risk-taking correlated with cognitive reflection scores and was significantly lower in the non-expert group compared to the other groups working in financial services. Traders in the current study showed no elevated preference to use ‘intuition’ in their decision-making compared to other groups. Overall, these results indicate that compared to non-expert participants financial traders have a higher self-rated tendency for reflective thinking and a greater propensity to inhibit the use of mental shortcuts (heuristics) in decision-making.

Background The aim of this study is to compare the perioperative and oncologic outcomes of open and laparoscopic approaches for concomitant resection of synchronous colorectal cancer and liver metastases. Methods Between 2006 and 2015, all patients undergoing combined resection of primary colorectal cancer and liver metastases were included in the study (n=43). Laparoscopic and open groups were compared regarding clinical, perioperative and oncologic outcomes. Results There were 29 patients in the open group and 14 patients in the laparoscopic group. The groups were similar regarding demographics, comorbidities, histopathological characteristics of the primary tumor and liver metastases. Postoperative complication rate (44.8% vs. 7.1%, P=0.016) was higher, and hospital stay (10 vs. 6.4 days, P=0.001) longer in the open compared to the laparoscopic group. Overall survival (OS) was comparable between the groups (P=0.10); whereas, disease-free survival (DFS) was longer in laparoscopic group (P=0.02). Conclusions According to the results, in patients, whose primary colorectal cancer and metastatic liver disease was amenable to a minimally invasive resection, a concomitant laparoscopic approach resulted in less morbidity without compromising oncologic outcomes. This suggests that a laparoscopic approach may be considered in appropriate patients by surgeons with experience in both advanced laparoscopic liver and colorectal techniques. PMID:28861371

This retrospective study aimed to compare the effectiveness of the embolization prevention mechanism of two types of embolic protection device (EPD)-a distal protection balloon (DPB) and a distal protection filter (DPF). Subjects were 164 patients scheduled to undergo carotid artery stenting: a DPB was used in 82 cases (DPB group) from April 2007 until June 2010, and a DPF was used in 82 cases (DPF group) from July 2010 to July 2011. Rates of positive findings on postoperative diffusion-weighted imaging (DWI) and stroke incidence were compared. Positive postoperative DWI results were found in 34 cases in the DPB group (41.4 %), but in only 22 cases in the DPF group (26.8 %), and there was only a small significant difference within the DPF group. In the DPB group, there was one case of transient ischemic attack (TIA) (1.2 %) and four cases of brain infarction (2 minor strokes, 2 major strokes; 4.9 %), compared to the DFP group with one case of TIA (1.2 %) and no cases of minor or major strokes. In this study, significantly lower rates of occurrence of DWI ischemic lesions and intraoperative embolization were associated with use of the DPF compared to the DPB.

White spot lesions (WSLs) are irreversible damages in orthodontic treatment due to excessive etching or demineralization by microorganisms. In this study, we conducted a mechanical and cell viability test to examine the antibacterial properties of 0.2% and 1% bioactive glass (BAG) and silver-doped and zinc-doped BAGs in a primer and evaluated their clinical applicability to prevent WSLs. The microhardness statistically significantly increased in the adhesive-containing BAG, while the other samples showed no statistically significant difference compared with the control group. The shear bond strength of all samples increased compared with that of the control group. The cell viability of the control and sample groups was similar within 24 h, but decreased slightly over 48 h. All samples showed antibacterial properties. Regarding remineralization property, the group containing 0.2% of the samples showed remineralization properties compared with the control group, but was not statistically significant; further, the group containing 1% of the samples showed a significant difference compared with the control group. Among them, the orthodontic bonding primer containing 1% silver-doped BAG showed the highest remineralization property. The new orthodontic bonding primer used in this study showed an antimicrobial effect, chemical remineralization effect, and WSL prevention as well as clinically applicable properties, both physically and biologically.

This is a randomized comparative study of the efficacy of celecoxib and loxoprofen in patients with frozen shoulder (scapulohumeral periarthritis). Patients with frozen shoulder who presented with pain as the symptom were divided at random into a celecoxib treatment group (100 mg/dose, twice daily; n = 37) and a loxoprofen treatment group (60 mg/dose, 3 times daily; n = 33). Medication was continued for 1-2 weeks in each group. Each patient was asked to rate the pain on a visual analog scale (score 0-5). This score significantly improved (indicating marked alleviation of pain) in both the celecoxib group (from 3.41 ± 0.86 before treatment to 2.30 ± 1.02 after treatment) and the loxoprofen group (from 3.73 ± 0.67 before treatment to 2.76 ± 0.96 after treatment). In the analysis of disappearance of pain, the percentage of patients showing disappearance of nocturnal pain was significantly higher in the celecoxib group (71.4 %) than in the loxoprofen group (36.8 %). The results confirm that celecoxib is comparable to loxoprofen in terms of analgesic efficacy in patients with frozen shoulder. Among other findings, we report that celecoxib was more effective for nocturnal pain than loxoprofen.

There is an increasing amount of evidence which links the pathogenesis of irritable bowel syndrome (IBS) with food IgG hyperreactivity. Some authors have suggested that food IgG hyperreactivity could be also involved in the pathophysiology of major depressive disorder (MDD). The aim of this study was to compare levels of serum IgG against 39 selected food antigens between three groups of participants: patients with MDD (MDD group), patients with IBS (IBS group) and healthy controls (HC group). The study included 65 participants (22 in the MDD group, 22 in the IBS group and 21 in the HC group). Serum IgG levels were examined using enzyme-linked immunosorbent assay (ELISA). Medical records, clinical data and laboratory results were collected for the analysis. IgG food hyperreactivity (interpreted as an average of levels of IgG antibodies above 7.5 µg/mL) was detected in 28 (43%) participants, including 14 (64%) from the MDD group, ten (46%) from the IBS group and four (19%) from the HC group. We found differences between extreme IgG levels in MDD versus HC groups and in IBS versus HC groups. Patients with MDD had significantly higher serum levels of total IgG antibodies and IgG against celery, garlic and gluten compared with healthy controls. The MDD group also had higher serum IgG levels against gluten compared with the IBS group. Our results suggest dissimilarity in immune responses against food proteins between the examined groups, with the highest immunoreactivity in the MDD group. Further studies are needed to repeat and confirm these results in bigger cohorts and also examine clinical utility of IgG-based elimination diet in patients with MDD and IBS. PMID:29710769

Sodium lactate seemed to improve fluid balance and avoid fluid overload. The objective of this study was to determine if these beneficial effects can be at least partly explained by an improvement in disseminated intravascular coagulation (DIC)-associated renal microvascular thrombosis. Ancillary work of an interventional randomized open label controlled experimental study. Fifteen female "Large White" pigs (2 months old) were challenged with intravenous infusion of E. coli endotoxin. Three groups of five animals were randomly assigned to receive different fluids: a treatment group received sodium lactate 11.2% (SL group); an isotonic control group received 0.9% NaCl (NC group); a hypertonic control group, with the same amount of osmoles and sodium than SL group, received sodium bicarbonate 8.4% (SB group). Glomerular filtration rate (GFR) markers, coagulation and inflammation parameters were measured over a 5-h period. Immediately after euthanasia, kidneys were withdrawn for histological study. Statistical analysis was performed with nonparametric tests and the Dunn correction for multiple comparisons. A p < 0.05 was considered significant. The direct immunofluorescence study revealed that the percentage of capillary sections thrombosed in glomerulus were significantly lesser in SL group [5 (0-28) %] compared to NC [64 (43-79) %, p = 0.01] and SB [64 (43-79), p = 0.03] groups. Alterations in platelet count and fibrinogen level occurred earlier and were significantly more pronounced in both control groups compared to SL group (p < 0.05 at 210 and 300 min). The increase in thrombin-antithrombin complexes was significantly higher in NC [754 (367-945) μg/mL; p = 0.03] and SB [463 (249-592) μg/mL; p = 0.03] groups than in SL group [176 (37-265) μg/mL]. At the end of the experiment, creatinine clearance was significantly higher in SL group [55.46 (30.07-67.85) mL/min] compared to NC group [1.52 (0.17-27.67) mL/min, p = 0.03]. In this study, we report that sodium lactate improves DIC-associated renal microvascular thrombosis and preserves GFR. These findings could at least partly explain the better fluid balance observed with sodium lactate infusion.

Reactive Balance in Individuals With Chronic Stroke: Biomechanical Factors Related to Perturbation-Induced Backward Falling.

PubMed

2016-03-01

An effective compensatory stepping response is the first line of defense for preventing a fall during sudden large external perturbations. The biomechanical factors that contribute to heightened fall risk in survivors of stroke, however, are not clearly understood. It is known that impending sensorimotor and balance deficits poststroke predispose these individuals to a risk of fall during sudden external perturbations. The purpose of this study was to examine the mechanism of fall risk in survivors of chronic stroke when exposed to sudden, slip-like forward perturbations in stance. This was a cross-sectional study. Fourteen individuals with stroke, 14 age-matched controls (AC group), and 14 young controls (YC group) were exposed to large-magnitude forward stance perturbations. Postural stability was computed as center of mass (COM) position (XCOM/BOS) and velocity (ẊCOM/BOS) relative to the base of support (BOS) at first step lift-off (LO) and touch-down (TD) and at second step TD. Limb support was quantified as vertical hip descent (Zhip) from baseline after perturbation onset. All participants showed a backward balance loss, with 71% of the stroke group experiencing a fall compared with no falls in the control groups (AC and YC groups). At first step LO, no between-group differences in XCOM/BOS and ẊCOM/BOS were noted. At first step TD, however, the stroke group had a significantly posterior XCOM/BOS and backward ẊCOM/BOS compared with the control groups. At second step TD, individuals with stroke were still more unstable (more posterior XCOM/BOS and backward ẊCOM/BOS) compared with the AC group. Individuals with stroke also showed greater peak Zhip compared with the control groups. Furthermore, the stroke group took a larger number of steps with shorter step length and delayed step initiation compared with the control groups. Although the study highlights the reactive balance deficits increasing fall risk in survivors of stroke compared with healthy adults, the study was restricted to individuals with chronic stroke only. It is likely that comparing compensatory stepping responses across different stages of recovery would enable clinicians to identify reactive balance deficits related to a specific stage of recovery. These findings suggest the inability of the survivors of stroke to regain postural stability with one or more compensatory steps, unlike their healthy counterparts. Such a response may expose them to a greater fall risk resulting from inefficient compensatory stepping and reduced vertical limb support. Therapeutic interventions for fall prevention, therefore, should focus on improving both reactive stepping and limb support. © 2016 American Physical Therapy Association.

Research on the effectiveness of distraction as a method of pain control is inconclusive. One mechanism pertains to the motivational relevance of distraction tasks. In this study the motivation to engage in a distraction task during pain was experimentally manipulated. Undergraduate students (N=73) participated in a cold pressor test (CPT) and were randomly assigned to three groups: a distraction-only group performed a tone-detection task during the CPT, a motivated-distraction group performed the same task and received a monetary reward for good task performance, and a control group did not perform the tone-detection task. Results indicated that engagement in the distraction task was better in the motivated-distraction group in comparison with the distraction-only group. Participants in both distraction groups experienced less pain compared to the control group. There were no overall differences in pain intensity between the two distraction groups. The effect of distraction was influenced by the level of catastrophic thinking about pain. For low catastrophizers, both distraction groups reported less pain as compared to the non-distracted control group. This was not the case for high catastrophizers. For high catastrophizers it mattered whether the distraction task was motivationally relevant: high catastrophizers reported less intense pain in the motivated-distraction group, as compared to the non-distracted control group. We conclude that increasing the motivational relevance of the distraction task may increase the effects of distraction, especially for those who catastrophize about pain.

The purpose of the present study was to compare the clinical and radiographic results and survival rates between computer-assisted and conventional closing wedge high tibial osteotomies (HTOs). Data from a consecutive cohort comprised of 75 computer-assisted HTOs and 75 conventional HTOs were retrospectively reviewed. The Knee Society knee and function scores, Hospital for Special Surgery (HSS) score and femorotibial angle (FTA) were compared between the two groups. Survival rates were also compared with procedure failure. The knee and function scores at one year postoperatively were slightly better in the computer-assisted group than those in conventional group (90.1 vs. 86.1) (82.0 vs. 76.0). The HSS scores at one year postoperatively were slightly better for the computer-assisted HTOs than those of conventional HTOs (89.5 vs. 81.8). The inlier of the postoperative FTA was wider in the computer-assisted group than that in the conventional HTO group (88.0% vs. 58.7%), and mean postoperative FTA was greater in the computer-assisted group that in the conventional HTO group (valgus 9.0° vs. valgus 7.6°, p<0.001). The five- and 10-year survival rates were 97.1% and 89.6%, respectively. No difference was detected in nine-year survival rates (p=0.369) between the two groups, although the clinical and radiographic results were better in the computer-assisted group that those in the conventional HTO group. Mid-term survival rates did not differ between computer-assisted and conventional HTOs. A comparative analysis of longer-term survival rate is required to demonstrate the long-term benefit of computer-assisted HTO. III. Copyright © 2015 Elsevier B.V. All rights reserved.

Rotator cuff tears are one of the most common causes of shoulder malfunction and pain, which lead to a significant reduction in the quality of life. This present study investigated the effects of subacromial platelet-rich plasma injections [i.e. autologous conditioned plasma (ACP) injections] as compared to standard subacromial cortisone injection therapy in 50 patients with partial rotator cuff tears. Before injection, and 6 weeks, 12 weeks and 6 months thereafter, the patients were assessed by the Constant-Murley score (CMS), the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), the simple shoulder test (SST) and a pain visual analogue scale (VAS). An MRI was also performed before and 6 months after injection. Both patient groups had statistically significant better shoulder score outcomes over time. ASES, SST and CMS outcomes after 12 versus 6 weeks were better in the ACP group as compared to the cortisone group. VAS, ASES and CMS outcomes after 12 weeks versus baseline in the ACP group were better as compared to the cortisone group. There was a statistically significant difference between ACP group and cortisone group 12 weeks after injection regarding VAS, ASES, SST and CMS in favour of the ACP group. The MRI showed an improvement in grade of tendinopathy in both groups, however, without statistically significant differences between the two groups. Compared with cortisone injections, ACP injections show earlier benefit as compared to cortisone injections although a statistically significant difference after 6 months could not be found. Therefore, subacromial ACP injections are a good alternative to subacromial cortisone injections, especially in patients with contraindication to cortisone. Therapeutic study, Level III.

To estimate the prevalence of hypertension-migraine comorbidity; to determine their demographic and clinical characteristics versus patients with hypertension or migraine alone; and to see whether a history of cerebrovascular events was more common in the comorbidity group. The MIRACLES, multicenter, cross-sectional, survey included 2973 patients with a known diagnosis of hypertension or migraine in a general practitioner setting in Italy. Five hundred and seventeen patients (17%) suffered from hypertension-migraine comorbidity, whereas 1271 (43%) suffered from hypertension only, and 1185 (40%) from migraine only. In the comorbidity group, the onset of comorbidity occurred at about 45 years of age, with migraine starting significantly later than in the migraine-only group, and hypertension significantly before than in the hypertension-only group; a familial history of both hypertension and migraine had a significantly higher frequency as compared with the hypertension and migraine group. Compared to hypertension (3.1%) and migraine (0.7%), the comorbidity group had a higher prevalence (4.4%) of history of cerebrovascular events, with an odds ratio of a predicted history of stroke/transient ischemic attack (TIA) of 1.76 [95% confidence interval (CI) 1.01-3.07] compared to the hypertension group. In patients without other recognized risk factors for stroke, stroke/TIA occurred more frequently in the comorbidity group, compared to the hypertension group. In the age range 40-49 years, prevalence of history of stroke/TIA was five-fold greater (4.8% in comorbidity vs. 0.9% in hypertension group). This cross-sectional study indicates that the prevalence of comorbidity hypertension-migraine is substantial and that patients with comorbidity have a higher probability of history of cerebrovascular events, compared to hypertensive patients.

In most health systems, Community Health Workers (CHWs) identify and screen for severe acute malnutrition (SAM) in the community. This study aimed to investigate the potential of integrating SAM identification and treatment delivered by CHWs, in order to improve the coverage of SAM treatment services. This multicentre, randomised intervention study was conducted in Kita, Southwest Mali between February 2015 and February 2016. Treatment for uncomplicated SAM was provided in health facilities in the control area, and by Community Health Workers and health facilities in the intervention area. Clinical outcomes (cure, death and defaulter ratios), treatment coverage and quality of care were examined in both the control and intervention group. Six hundred ninety nine children were admitted to the intervention group and 235 children to the control group. The intervention group reported cure ratios of 94.2% compared to 88.6% in the control group (risk ratio 1.07 [95% CI 1.01; 1.13]). Defaulter ratios were twice as high in the control group compared to the intervention group (10.8% vs 4.5%; RR 0.42 [95% CI 0.25; 0.71]). Differences in mortality ratios were not statistically significant (0.9% in the intervention group compared to 0.8% in the control group). Coverage rates in December 2015 were 86.7% in intervention group compared to 41.6% in the control (p < 0.0001). With minimal training, CHWs are able to appropriately treat SAM in the community. Allowing CHWs to treat SAM reduces defaulter ratios without compromising treatment outcomes and can lead to improved access to treatment.

The present study aimed to compare the effect of autograft or allograft anterior cruciate ligament (ACL) reconstruction on the expressions of lipoxygenases (LOXs) and matrix metalloproteinases (MMPs) in a New Zealand white rabbit model. New Zealand white rabbits were divided randomly into control, sham, autograft and allograft groups. At the 4th and 8th week after operation, biomechanical testing was performed to measure the primary length, cross-sectional area, maximum tensile load and stiffness of ACL, and HE staining was used to observe cell morphology and fibre alignment of ACL. At the 2nd, 4th and 8th week after operation, quantitative real-time PCR (qRT-PCR), Western blotting and immunohistochemistry were applied to detect LOXs and MMPs expressions, and expressions of adenomatous polyposis coli (APC)/Wnt signalling pathway-related proteins. At the 4th and 8th week after operation, the maximum tensile load and stiffness were higher in the autograft group than in the allograft group, and the values at the 8th week were higher than those at the 4th week after operation. The fibroblast proliferation in the allograft group was more significant than that in the autograft group. Compared with the control group, LOXs and MMPs expressions and the positive expression rates of LOXs and MMPs proteins were elevated, and the values in the allograft group were higher than those in the autograft group at all time points. At 8th week after operation, compared with the autograft group, Wnt expression was higher and APC expression was lower in the allograft group. Autograft and allograft ACL reconstruction can promote LOXs and MMPs expressions by activating the APC/Wnt signalling pathway. PMID:28275205

Dysphagia is encountered in a large proportion of patients with lung cancer and is associated with malnutrition and a poor quality of life. This study compared the clinical outcomes of self-expandable metallic stent (SEMS) insertion and percutaneous gastrostomy (PG) feeding for patients with lung cancer and dysphagia. A total of 261 patients with lung cancer, who underwent either SEMS insertion (stent group) or PG (gastrostomy group) as an initial treatment procedure for dysphagia between July 1997 and July 2015 at the Samsung Medical Center, were reviewed retrospectively, and 84 patients with esophageal obstruction were identified. The clinical outcomes, including the overall survival, additional intervention, complications, and post-procedural nutritional status in the two groups, were compared. Among the 84 patients finally analyzed, 68 patients received SEMS insertion and 16 had PG. The stent group had less cervical obstruction and more mid-esophageal obstruction than the gastrostomy group. The Kaplan-Meier curves revealed similar overall survival in the two groups. Multivariate analysis showed that the two modalities had similar survival rates (PG compared with SEMS insertion, hazard ratio 0.682, p=0.219). Fifteen patients (22.1%) in the stent group received additional intervention, whereas there was no case in the gastrostomy group (p=0.063). The decrease in the serum albumin level after the procedure was lower in the gastrostomy group than in the stent group (-0.20±0.54 g/dL vs. -0.65±0.57 g/dL, p=0.013). SEMS insertion and PG feeding for relieving dysphagia by lung cancer had a comparable survival outcome. On the other hand, PG was associated with a better nutritional status.

The aims of this study were to investigate and describe the Oral Health Related Quality of Life (OHRQoL) in a socially endangered group of people and to compare the OHRQoL to other patient groups. About 294 socially endangered persons attending a volunteer clinic in Copenhagen Denmark filled in the OHIP-14 questionnaire. The group was compared in mean score and reported problems to a group of patients with tooth loss and about to have a removable dental prosthesis (RDP), a group with tooth loss about to have a fixed dental prosthesis (FDP) and a control group without tooth loss. Significantly higher OHIP-14 score was seen in the socially endangered group (15.5 (SD 12.6)) compared with the control (1.9 (SD 2.7)) and the FDP group (9.4 (SD 8.2)) but not the RDP group (13.1 (SD 10.5)). This difference was not changed after stratifying in age groups. Problems related to psychological disability, social disability, and handicap were more frequent in the social endangered group than for the other groups. The items pain, tense, diet, relax, life, and function stand out as problems in the socially endangered group compared to the other groups. The OHRQoL is highly impaired in the socially endangered persons and at least to the level of persons with great tooth loss about to have an RDP. The problems seem to be more handicapping in the socially endangered compared with other patient groups known to have high impairment.

To investigate and compare the efficacy and safety of two kinds of Qinbai ointment prepared conventionally and finely (C-QBO and F-QBO) in treating psoriasis in the active stage of blood-heat syndrome type, and to observe their influences on vaginal epithelial cell mitosis, also on keratinization of caudal flakes in mice. Adopting randomized, single-blinded, controlled design, 93 patients administered orally with Liangxue Huoxue Decoction were randomized into three groups treated externally with C-QBO, F-QBO and white vaseline respectively, applied twice a day for 8 weeks. The safety was checked and the changes of modified psoriasis area severity index (PASI), as well as the conditions of skin lesions (size, erythema, infiltration, squama, and itching) and symptom improving time were compared. Experimental study 1: Mice were randomized into the model group, the C-QBO group, the F-QBO group and the blank group, 7 in each group. Their vaginal epithelial cell mitosis indices were compared after 3 days of treatment with corresponding remedies. Experimental study 2: Mice were randomized into the C-QBO group, the F-QBO group and the blank group, 7 in each group. After the mice had been treated with corresponding remedies for 28 days, the granular layer formation in their caudal scales was compared. The markedly effective rate was 63.3% (25/30) in the C-QBO group, 66.7% (20/30) in the F-QBO group, and 36.7% (11/30) in the control group. No statistical difference was showen between the two QBO treated groups (P > 0.05), but that in both of them was significantly different from that in the control group (P < 0.05). PASI scores lowered after treatment in all the three groups (P < 0.01), but the improvement in the two QBO groups was better than that in the control group (P < 0.05); the conditions of skin lesion were improved in all groups, but the improvements were more significant in the two QBO groups in terms of squama, infiltration and itching (P < 0.05), in aspects of improving time on erythema, infiltration and itching, especially the itching, F-QBO was superior to the C-QBO. Experimental study 1: The mitosis index in both QBO groups was lower than that in the blank group and the model group (P < 0.01). Experimental study 2: Number of scales with granular layer formation was higher in the two QBO groups than in the blank group (P < 0.01). C-QBO and F-QBO can effectively relieve the skin lesion of psoriasis patients in the active stage of blood-heat type, and they could also promote the formation of epithelial granular layer in the caudal scales of mice.

The aim of the following study is to evaluate the effect of life-style modification on postmenopausal (PM) overweight and obese Indian women in a randomized controlled 24 week study. Two groups were formed Group I (n = 30) was designated as intervention (dietary and exercise group) and Group II (n = 24) served as control. Comparison of weight, waist circumference (WC) and body mass index (BMI) were made and compared among two groups at 4, 8, 16 and 24 weeks. Mean age at menopause was 48.35 years versus 49.65 years; mean number of menopausal symptoms were 5.70 ± 1.76 versus 5.10 ± 1.56 and mean duration since menopause was 2.70 versus 2.90 years in Groups I and II respectively. When the effect of Group I and control on weight was compared at 4, 8, 16 and 24 weeks, there was no significant difference between them up to 8 week. At 8 weeks Group I caused a significant decrease in weight (P ≤ 0.05) when compared with control arm and which continued throughout the study period (P < 0.05) at both 16 and 24 weeks. Group I produced a significant reduction in WC from 8 weeks onwards up to 24 weeks (P ≤ 0.05). BMI was statistically significant in Group I and the effect started at 4(th) week (P ≤ 0.05) and the differences in BMI reduction were highly significant at 16(th) and 24(th) weeks (P ≤ 0.001). The results of the present study strongly recommend the life-style management to be incorporated in daily style of postmenopausal women under controlled supervision.

The aim of the present study was to investigate the usefulness of the transanal drainage tube for prevention of anastomotic leakage and bleeding after anterior resection for rectal cancer. Between January 2007 and May 2011 a nonrandomized prospective study of patients undergoing anterior resection for rectal cancer was done. The patients were divided into the transanal drainage tube (TDT) and non-transanal drainage tube (NTDT) groups according to whether the transanal drainage tube was used in the operation. Clinical characteristics and postoperative complications were compared between the TDT and NTDT groups. The study included 81 patients in the TDT group and 77 patients in the NTDT group. In the TDT group, anastomotic leakage occurred in 2 patients and no anastomotic bleeding occurred. In the NTDT group, anastomotic leakage occurred in 7 patients and anastomotic bleeding occurred in 2 patients. The TDT group had significantly fewer anastomotic complications compared with the NTDT group (2.5 vs 11.7 %; P = 0.029). Furthermore, the TDT group showed an obvious reduction in the rate of anastomotic leakage and anastomotic bleeding compared with the NTDT group (2.5 vs 7.8 % and 0.0 vs 2.6 %), but because the number of cases is relatively small, the difference did not reach statistical significance (P = 0.160 and P = 0.236). The use of a transanal drainage tube in anterior resection for rectal cancer may be a simple, safe, and effective means of preventing or reducing the occurrence of anastomotic leakage and bleeding. A larger-scale single or multi-center prospective randomized study or a meta-analysis including similar studies is necessary for further elucidation of this issue.

The purpose of this study was to measure and compare the difference between rate of en-masse retraction with mini-implant and molar anchorage. A comparative study consisting of 14 patients (all females) randomized into 2 groups. Seven in group I (nonimplant) molar was used as anchor for en-masse retraction of anterior teeth (mean age 16 years SD +/- 1.41). In group II (implant), mini-implant was used as anchorage to retract the anterior teeth (mean age 17.36 SD +/- 1.35). In both groups, all first premolars were extracted. After leveling and aligning, surgical steel mini-implant of 1.3 mm in diameter and 8 mm in length were placed between the roots of second premolar and first molar in the maxilla in the implant group. Implants were immediately loaded with 2 N of force. In nonimplant group molar was used as anchorage. The retraction and postretraction lateral cephalograms were taken. Rate of retraction and anchor loss were measured by using pterygoid vertical in maxilla. Four implants became loose during the treatment, which were subsequently replaced. The stability of surgical steel in this study was 71.4%. Student t test were used to analyze the treatment charges in 2 groups. Mean anchor loss in maxilla in nonimplant group. No differences in the mean rate of retraction time were noted in both groups. Mini-implants provided absolute anchorage in patients requiring maximum anterior retraction. No differences in the mean retraction time were noted between 2 groups.

Knowledge Retention for Computer Simulations: A study comparing virtual and hands-on laboratories

NASA Astrophysics Data System (ADS)

Croom, John R., III

The use of virtual laboratories has the potential to change physics education. These low-cost, interactive computer activities interest students, allow for easy setup, and give educators a way to teach laboratory based online classes. This study investigated whether virtual laboratories could replace traditional hands-on laboratories and whether students could retain the same long-term knowledge in virtual laboratories as compared to hands-on laboratories. This study is a quantitative quasi-experiment that used a multiple posttest design to determine if students using virtual laboratories would retain the same knowledge as students who performed hands-on laboratories after 9 weeks. The study was composed of 336 students from 14 school districts. Students had their performances on the laboratories and their retention of the laboratories compared to a series of factors that might have affected their retention using a pretest and two posttests, which were compared using a t test. The results showed no significant difference in short-term learning between the hands-on laboratory groups and virtual laboratory groups. There was, however, a significant difference (p = .005) between the groups in long-term retention; students in the hands-on laboratory groups retained more information than those in the virtual laboratory groups. These results suggest that long-term learning is enhanced when a laboratory contains a hands-on component. Finally, the results showed that both groups of students felt their particular laboratory style was superior to the alternative method. The findings of this study can be used to improve the integration of virtual laboratories into science curriculum.

The axillary vein is an easily accessible vessel that can be used for ultrasound-guided central vascular access and offers an alternative to the internal jugular and subclavian veins. The objective of this study was to identify which transducer orientation, longitudinal or transverse, is better for imaging the axillary vein with ultrasound. We analyzed 236 patients who had undergone central venous cannulation of axillary vein in this retrospective study. Patients were divided into two groups, the longitudinal approach group (n=120) and transverse approach group (n=116). Recorded the one-attempt success rate, operation time, arterial puncture rate and pneumothorax rate. We perform chest radiography to confirm pneumothorax on all patients. We compared the one-attempt success rate, operation time, arterial puncture rate and pneumothorax rate between the two groups. The two groups were comparable with clinical characters of patients. The overall success rates of the longitudinal group and the transverse group were both 100%. The rate of one-attempt success in the longitudinal approach group is higher than the transverse approach group (91.7% vs. 82.8%, P=0.040). The transverse approach group had shorter operation time than the longitudinal group (184.7±8.1 vs. 287.5±19.6 seconds, P=0.000). The two groups had lower postoperative complications. Arterial puncture occurred in 1 of 120 longitudinal and 2 of 116 transverse attempts and this difference was no significant (P=0.541). No pneumothorax occurred in the two groups. The longitudinal approach during ultrasound-guided axillary vein cannulation is associated with greater one-attempt success rate compared with the transverse approach by experienced operators. The transverse approach has shorter operation time. The two groups have lower postoperative complications and are comparable with pneumothorax and arterial puncture.

The aim of this study was to compare the efficacy of different instruments on biofilm removal from implant supported restorations. The study was designed as comparative multicenter clinical study including patients proceeding from the Milan, Naples, and Buenos Aires, with a peri-implant mucositis. Implants enrolled for the study were allocated in 4 groups and treated with ultrasonic scalers with plastic tips, with titanium curettes, with airflow with glycine powder, and with rubber cup and polishing paste, respectively. mPI was assessed at baseline, immediately after therapy, at 1, 3, and 6 months. mBI, PD, and REC were assessed at baseline, 1, 3, and 6 months. All parameters were recorded on six sites per implant. Kruskal-Wallis and Mann-Whitney tests were used to compare groups and centers. A generalized linear model for repeated measures was chosen for inter-group comparison. An intra-group comparison was performed with repeated measure ANOVA test to assess differences between baseline and recalls. A total of 89 patients (39 males, 50 females) were enrolled in the study, and 141 implants were available for the analysis. 55 implants were enrolled in University of Buenos Aires, 32 in University of Milan, and 54 in University of Naples. There were no significant differences between the four groups in inflammatory status reduction of peri-implant mucosa. Non-surgical therapy is effective in reducing peri-implant mucositis. Sonic scaler with plastic tip and rubber cup with polishing paste showed higher efficacy when compared with titanium curettes or airflow with glycine powder. © 2014 John Wiley & Sons A/S.

There are very few studies evaluating efficacy of platelet-rich plasma (PRP) in hair restoration and its combination with microneedling. As far as ascertained, there is no study to evaluate efficacy of microneedling with PRP plus topical minoxidil (5%) versus topical minoxidil (5%) alone in androgenetic alopecia (AGA). This study aims (1) to compare the efficacy of (a) topical minoxidil (5%) alone and (b) topical minoxidil (5%) + microneedling with PRP in men between 18 and 50 years with AGA Grade III to V vertex (Norwood-Hamilton scale) and (2) to perform objective and subjective evaluation based on clinical improvement and photographic evidence. The study was conducted in the outpatient department of dermatology, venereology, and leprology in tertiary care hospital. It was open, prospective study. Fifty patients with AGA were selected on the basis of inclusion and exclusion criteria. These patients were randomly divided into two groups of 25 patients each and were given following treatment: (i) Group A: topical minoxidil (5%) alone and (ii) Group B: topical minoxidil (5%) + microneedling with platelet-rich plasma (PRP). Patients were assessed before starting the treatment and at the end of 6 months on the basis of (a) Patient's self-assessment based on standardized seven-point scale compared with baseline (b) Physician's assessment based on standardized seven-point scale of hair growth compared with baseline. There was a significant improvement ( P < 0.05) in both patients' assessment and investigator's assessment in Group B as compared to Group A at the end of 6 months. Microneedling with PRP is safe, effective, and a promising tool for the management of AGA.

The objectives of this study were to compare the clinical outcomes of the two common bone marrow stimulation techniques such as subchondral drilling and microfracture for symptomatic osteochondral lesions of the talus and to evaluate prognostic factors affecting the outcomes. Ninety patients (90 ankles) who underwent arthroscopic bone marrow stimulation for small- to mid-sized osteochondral lesions of the talus constituted the study cohort. The 90 ankles were divided into two groups: a drilling group (40 ankles) and a microfracture group (50 ankles). Each group was matched for age and gender, and both groups had characteristics similar to those obtained from pre-operative demographic data. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and the ankle activity score (AAS) were used to compare clinical outcomes, during a mean follow-up period of 43 months. The median AOFAS scores were 66.0 points (51-80) in drilling group and 66.5 points (45-81) in microfracture group pre-operatively, and these improved to 89.4 points (77-100) and 90.1 points (69-100) at the final follow-up, respectively. The median VAS scores improved at the final follow-up compared with the pre-operative condition. The median AAS for the drilling group improved from 4.5 (1-6) pre-operatively to 6.0 (1-8) at the final follow-up, while those for the microfracture group improved from 3.0 (2-8) to 6.0 (3-9). No significant differences were observed between the two groups in terms of the AOFAS scores, VAS, and AAS. The arthroscopic subchondral drilling and microfracture techniques that were used to stimulate bone marrow showed similar clinical outcomes. The results of this study suggest that both techniques are effective and reliable in treating small- to mid-sized osteochondral lesions of the talus, regardless of which of the two techniques is used.

Introduction: Encoding of CE-chirp and click stimuli in auditory system was studied using auditory brainstem responses (ABRs) among individuals with and without noise exposure. Materials and Methods: The study consisted of two groups. Group 1 (experimental group) consisted of 20 (40 ears) individuals exposed to occupational noise with hearing thresholds within 25 dB HL. They were further divided into three subgroups based on duration of noise exposure (0–5 years of exposure-T1, 5–10 years of exposure-T2, and >10 years of exposure-T3). Group 2 (control group) consisted of 20 individuals (40 ears). Absolute latency and amplitude of waves I, III, and V were compared between the two groups for both click and CE-chirp stimuli. T1, T2, and T3 groups were compared for the same parameters to see the effect of noise exposure duration on CE-chirp and click ABR. Result: In Click ABR, while both the parameters for wave III were significantly poorer for the experimental group, wave V showed a significant decline in terms of amplitude only. There was no significant difference obtained for any of the parameters for wave I. In CE-Chirp ABR, the latencies for all three waves were significantly prolonged in the experimental group. However, there was a significant decrease in terms of amplitude in only wave V for the same group. Discussion: Compared to click evoked ABR, CE-Chirp ABR was found to be more sensitive in comparison of latency parameters in individuals with occupational noise exposure. Monitoring of early pathological changes at the brainstem level can be studied effectively by using CE-Chirp stimulus in comparison to click stimulus. Conclusion: This study indicates that ABR's obtained with CE-chirp stimuli serves as an effective tool to identify the early pathological changes due to occupational noise exposure when compared to click evoked ABR.

We wished to compare the endotracheal tube (ETT) cuff pressure inflated with air or alkalinized lignocaine during anesthesia and evaluate clinical symptoms such as coughing and sore throat (postoperative sore throat [POST]) following tracheal extubation. This was a prospective randomized controlled study conducted in a tertiary care set up over a period of 1 year. We included 100 patients in age group of 18-65 years posted for elective surgeries of duration more than 90 min under general anesthesia with N 2 O-O 2 mixture. Patients were randomized using computer-generated randomization table into air and lignocaine group. The ETT cuff was inflated with air or alkalinized lignocaine (2% lignocaine with 7.5% sodium bicarbonate, in the proportions of 19.0:1.0 ml) to the volume that prevented air leak using cuff pressure manometer. After extubation, an independent observer blinded to study group recorded the presence or absence of coughing and POST at immediately, 1 h and 24 h postoperatively. Demographic data, baseline characteristics (American Society of Anesthesiologists grade, intracuff volume/cuff pressure at start of surgery), and duration of anesthesia were comparable among study groups ( P > 0.05). Cuff pressure and volume achieved in the end of surgery were much higher in air group as compared to lignocaine group ( P < 0.05). Incidence of coughing and POST at immediately, 1 h and 24 h postoperatively was significantly higher in air group compared to lignocaine group. Impact of duration of anesthesia on rise in cuff pressure was significantly higher in air group and its effect on cuff-induced laryngotracheal morbidity was significant in both air and lignocaine group. This study showed the significance of use of alkalinized 2% lignocaine in prevention of rise of cuff pressure and incidence of coughing and POST. Duration of anesthesia has also a significant effect on incidence of postoperative trachea-laryngeal morbidity.

Personality and antisocial behavior in children and adolescents: an enquiry into Eysenck's and Gray's theories.

Two studies were conducted to test the hypotheses derived from Eysenck's and Gray's theories of personality regarding antisocial behavior. For this purpose the Eysenck Personality Questionnaire (Junior) (EPQ-Junior) and a card task aimed at measuring sensitivity to reward were used in each of the studies. The first study compared a group of juvenile delinquents with a group of nondelinquents and the second study compared a group of severely conduct-disordered children with a group of normal children. The results did not support Eysenck's claim that delinquents score higher than their normal counterparts on extraversion, neuroticism, and psychoticism. Some support was found for the hypothesis derived from Gray's theory: Children and adolescents with severe antisocial behavior were more sensitive to rewards than their normal counterparts.

Objective: To study the effect of different starvation levels on cognitive ability in mice. Method: Mice were randomly divided into four groups: normal group, dieting group A, dieting group B, dieting group C. The mice of normal group were given normal feeding amount, the rest of groups were given 3/4 of normal feeding amount, 2/4 of normal feeding amount and 1/4 of normal feeding amount. After feeding mice four days, the weight was observed and T-maze experiment, Morris water maze test, open field test and Serum Catalase activity were detected. Result: Compared with the normal group, the correct rate of the intervention group in the T-maze experiment was decreased and dieting group A> dieting group B> dieting group C. In the Morris water maze test, Compared with the normal group, the correct rate of the intervention group was increased. Among these three intervention groups, dieting group A had the highest correct rate and the difference of dieting group B and dieting group C were similar. In the open field test, Compared with the normal group, the exploration rate of the surrounding environment in the intervention group was increased. In the Serum Catalase test, Compared with the normal group, the activities of serum peroxidase in the intervention groups were decreased and dieting group A> dieting group B> dieting group C. Conclusion: A certain level of starvation could affect the cognitive ability of mice. In a certain range, the level of starvation is inversely proportional to cognitive ability in mice.

To evaluate the efficacy and safety profile of paracetamol in comparison with tramadol for pain relief during active labor. Prospective, randomized, double-blind study. Maternity Wing of the Postgraduate Institute of Medical Education and Research, Chandigarh. Sixty laboring, primiparous, full-term parturients with uncomplicated, singleton pregnancy in spontaneous labor and cervical dilatation of 3-5 cm. Parturients were randomized into 2 groups to receive either 1 mg/kg of tramadol intramuscularly (group T; n = 29) or 1 g of paracetamol intravenously (group P; n = 30). Same doses of the drugs were repeated after 4 hours of initial dose. Primary outcome of the study was to assess the analgesic efficacy of the 2 drugs as measured by visual analog scale (VAS) score. Secondary outcome recorded was duration of labor, presence of any maternal, or fetal adverse events during the study. Both the groups showed comparable VAS scores at all times of observation. Lower mean VAS scores were reported in both the groups till 120 minutes only. The duration of first stage of labor was shorter in group P (248.00 ± 98.171 vs 340.63 ± 111.592 minutes; P = .003). The duration of second stage of labor was comparable between the 2 groups. Higher incidence of maternal side effects such as nausea/vomiting and sedation was associated with the use of tramadol. Neonatal outcome was comparable. Intravenous paracetamol provides comparable analgesia as intramuscular tramadol during active labor. Copyright © 2014 Elsevier Inc. All rights reserved.

Objective: The aims of the study are to assess the marginal accuracy of base metal and titanium alloy casting and to evaluate the effect of repeated ceramic firing on the marginal accuracy of base metal and titanium alloy castings. Materials and Methods: Twenty metal copings were fabricated with each casting material. Specimens were divided into 4 groups of 10 each representing base metal alloys castings without (Group A) and with metal shoulder margin (Group B), titanium castings without (Group C) and with metal shoulder margin (Group D). The measurement of fit of the metal copings was carried out before the ceramic firing at four different points and the same was followed after porcelain build-up. Results: Significant difference was found when Ni–Cr alloy samples were compared with Grade II titanium samples both before and after ceramic firings. The titanium castings with metal shoulder margin showed highest microgap among all the materials tested. Conclusions: Based on the results that were found and within the limitations of the study design, it can be concluded that there is marginal discrepancy in the copings made from Ni–Cr and Grade II titanium. This marginal discrepancy increased after ceramic firing cycles for both Ni–Cr and Grade II titanium. The comparative statistical analysis for copings with metal-collar showed maximum discrepancy for Group D. The comparative statistical analysis for copings without metal-collar showed maximum discrepancy for Group C. PMID:24926205

Effectiveness of a 'Global Postural Reeducation' program for persistent Low Back Pain: a non-randomized controlled trial

PubMed Central

2010-01-01

Background The aim of this non-randomized controlled trial was to evaluate the effectiveness of a Global Postural Reeducation (GPR) program as compared to a Stabilization Exercise (SE) program in subjects with persistent low back pain (LBP) at short- and mid-term follow-up (ie. 3 and 6 months). Methods According to inclusion and exclusion criteria, 100 patients with a primary complaint of persistent LBP were enrolled in the study: 50 were allocated to the GPR group and 50 to the SE group. Primary outcome measures were Roland and Morris Disability Questionnaire (RMDQ) and Oswestry Disability Index (ODI). Secondary outcome measures were lumbar Visual Analogue Scale (VAS) and Fingertip-to-floor test (FFT). Data were collected at baseline and at 3/6 months by health care professionals unaware of the study. An intention to treat approach was used to analyze participants according to the group to which they were originally assigned. Results Of the 100 patients initially included in the study, 78 patients completed the study: 42 in the GPR group and 36 in the SE group. At baseline, the two groups did not differ significantly with respect to gender, age, BMI and outcome measures. Comparing the differences between groups at short- and mid-term follow-up, the GPR group revealed a significant reduction (from baseline) in all outcome measures with respect to the SE group. The ordered logistic regression model showed an increased likelihood of definitive improvement (reduction from baseline of at least 30% in RMDQ and VAS scores) for the GPR group compared to the SE group (OR 3.9, 95% CI 2.7 to 5.7). Conclusions Our findings suggest that a GPR intervention in subjects with persistent LBP induces a greater improvement on pain and disability as compared to a SE program. These results must be confirmed by further studies with higher methodological standards, including randomization, larger sample size, longer follow-up and subgrouping of the LBP subjects.

The aim of the current study was to investigate in-hospital falls among children with neurological or neurodevelopmental conditions and investigated associated child characteristics. A cross-sectional, correlational study design was used in this study. A total of 446 patients were enrolled in the study, of which 298 were admitted with neurological conditions and 148 with neurodevelopmental conditions. Intelligent quotient (IQ) was assessed according to age, and the Humpty Dumpty Falls Scale (HDFS) was completed and scored for each participant. The neurodevelopmental group showed higher HDFS total mean score (p = .001) compared to the neurological group. We found that fall rates are more frequent (p = .003) in the neurodevelopmental group (12.9%) compared with the neurological group (5.1%). In addition, we found that, in both groups, HDFS total mean score correlates negatively with children's age, gender and IQ. The results of this study suggest that the fall prevention programs must be implemented in children with neurodevelopmental conditions, not only in children with neurological conditions.

Sample size for post-marketing safety studies based on historical controls.

Wu, Yu-te; Makuch, Robert W

2010-08-01

As part of a drug's entire life cycle, post-marketing studies are an important part in the identification of rare, serious adverse events. Recently, the US Food and Drug Administration (FDA) has begun to implement new post-marketing safety mandates as a consequence of increased emphasis on safety. The purpose of this research is to provide exact sample size formula for the proposed hybrid design, based on a two-group cohort study with incorporation of historical external data. Exact sample size formula based on the Poisson distribution is developed, because the detection of rare events is our outcome of interest. Performance of exact method is compared to its approximate large-sample theory counterpart. The proposed hybrid design requires a smaller sample size compared to the standard, two-group prospective study design. In addition, the exact method reduces the number of subjects required in the treatment group by up to 30% compared to the approximate method for the study scenarios examined. The proposed hybrid design satisfies the advantages and rationale of the two-group design with smaller sample sizes generally required. 2010 John Wiley & Sons, Ltd.

OBJECTIVE This study was performed to identify the angiographic features of hemorrhagic-onset moyamoya disease (MMD) in comparison with those of patients with ischemic-onset MMD. METHODS This case-control study compared the data set of the Japan Adult Moyamoya (JAM) Trial with the angiographic data of adult patients with ischemic-onset MMD. The authors analyzed angiograms obtained at onset, classifying the collaterals into 3 subtypes: lenticulostriate anastomosis, thalamic anastomosis, and choroidal anastomosis. They then compared the extent of these collaterals, as indicated by the collateral development grade from 0 to 2 in each subtype, between the JAM Trial group and the ischemic-onset group. They also compared the involvement of the posterior cerebral artery (PCA) and Suzuki's angiographic staging between each group. RESULTS Among 89 ischemic-onset patients, 103 symptomatic hemispheres in 80 patients were analyzed and compared with 75 hemorrhagic hemispheres from the JAM Trial. The hemorrhagic-onset patients showed a significantly higher proportion of thalamic anastomosis (p = 0.043) and choroidal anastomosis (< 0.001), as indicated by grade 2 in each subtype, compared with ischemic-onset patients. Suzuki's angiographic staging was significantly higher in the hemorrhagic group (< 0.038). There was no difference in the extent of lenticulostriate anastomosis and PCA involvement between the groups. CONCLUSIONS In adult MMD, the characteristic pattern of the abnormal vascular networks at the base of the brain is different between each onset type. In light of the more prominent development of thalamic and choroidal anastomosis in the JAM Trial group in the present study, development of these collaterals, especially the choroidal collateral extending beyond the lateral ventricle, may play a critical role in hemorrhagic presentation in MMD.

Although oncoplastic breast surgery is used to resect larger tumors with lower re-excision rates compared to standard wide local excision (sWLE), criticisms of oncoplastic surgery include a longer-albeit, well concealed-scar, longer operating time and hospital stay, and increased risk of complications. Round block technique has been reported to be very suitable for patients with relatively smaller breasts and minimal ptosis. We aim to determine if round block technique will result in operative parameters comparable with sWLE. Breast cancer patients who underwent a round block procedure from 1st May 2014 to 31st January 2016 were included in the study. These patients were then matched for the type of axillary procedure, on a one to one basis, with breast cancer patients who had undergone sWLE from 1st August 2011 to 31st January 2016. The operative parameters between the 2 groups were compared. 22 patients were included in the study. Patient demographics and histologic parameters were similar in the 2 groups. No complications were reported in either group. The mean operating time was 122 and 114 minutes in the round block and sWLE groups, respectively (P=0.64). Length of stay was similar in the 2 groups (P=0.11). Round block patients had better cosmesis and lower re-excision rates. A higher rate of recurrence was observed in the sWLE group. The round block technique has comparable operative parameters to sWLE with no evidence of increased complications. Lower re-excision rate and better cosmesis were observed in the round block patients suggesting that the round block technique is not only comparable in general, but may have advantages to sWLE in selected cases.

Stress has been acknowledged as one of the aetiologies of female reproductive dysfunction, yet the mechanismsinvolved are not totally elucidated. Based on the paucity of information on how predator-induced stress (PS) affects oestrouscycle in rats, this study was designed to investigate the effect of PS on the oestrous cycle in rats. Forty-eight (48) SpragueDawley rats were used for this study. They were randomly divided into Control and PS group. Each group was divided intofour subgroups (n=6/group) according to the phases of oestrous cycle. Stress was induced by exposing rats to cat (predator)for 60 minutes/day for 14 consecutive days. PS caused significant disruption of the oestrous cycle. In animals subjected toPS at proestrus (PS-proestrus) and oestrus (PS-oestrus), percentage occurrence of proestrus, oestrus and metestrus phaseswere significantly reduced compared with control. In animals subjected to PS at metestrus (PS-metestrus) and diestrus (PSdiestrus), percentage occurrence of oestrus phase was not significantly affected. In all animals exposed to PS, percentageoccurrence of diestrus was significantly increased regardless of the phase of first exposure compared with control.Corticosterone and prolactin levels were significantly elevated in PS groups compared with control. Progesterone wassignificantly increased in animals at diestrus phase compared with oestrus phase and respective phases in control. Oestradiolwas significantly reduced in PS group compared with control at oestrus phase but not significantly different at diestrus phase.Luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels were significantly lower in PS groups at oestrusphase compared with diestrus phase. This study shows that PS disrupts the oestrous cycle secondary to perturbation ofhormonal control of female reproduction and is influenced by the phase at first exposure to stress.

Background Cocoa polyphenols have been shown to reduce stress in highly stressed, as well as normal healthy individuals, we wondered whether commercially available chocolate could reduce perceived stress in medical students or not, so we decided to conduct this study. Methods Sixty students were divided into 3 groups (10 males + 10 females/group): i) Dark chocolate (DC) ii) Milk chocolate (MC) iii) White chocolate (WC). Subjects answered a PSS-10 (Perceived Stress Scale) questionnaire at baseline and after consumption of chocolate (40 g/day) for 2 weeks. Data were analyzed by using Microsoft Excel and SPSS version 20. Descriptive analyses were conducted. Means were compared across the study groups by One-Way ANOVA and within the same group by paired ‘t’ test. Results Mean stress scores compared between the groups by ANOVA revealed statistically not significant differences before (F =0.505; P=0.606) and after chocolate consumption (F=0.188; P=0.829). Paired ‘t’ test compared stress scores means before and after chocolate supplementation within the same group and exhibited statistically significant decrease in DC (t = 2.341; p value = 0.03) and MC (t = 3.302; p value = 0.004) groups. Mean stress scores decreased, on average, by approximately 2 and 3 points in DC and MC groups, respectively, at 95% Confidence Interval. The difference was more evident and statistically significant in female students as compared to the males. Conclusion Consumption of 40 g of Dark and Milk chocolate daily during a period of 2 weeks appear to be an effective way to reduce perceived stress in females. PMID:25780358

Background. This study evaluated the effect of two prophylaxis techniques on the marginal gap of CI V resin-modified glass-ionomer restorations. Methods. Standard Cl V cavities were prepared on the buccal surfaces of 48 sound bovine mandibular incisors in this in vitro study. After restoration of the cavities with GC Fuji II LC resin-modified glass-ionomer, the samples were randomly assigned to 3 groups of 16. In group 1, the prophylactic procedures were carried out with rubber cup and pumice powder and in group 2 with air-powder polishing device (APD). In group 3 (control), the samples did not undergo any prophylactic procedures. Then the marginal gaps were measured. Two-way ANOVA was used to compare marginal gaps at the occlusal and gingival margins between the groups. Post hoc Tukey test was used for two-by-two comparisons. Statistical significance was set at P < 0.05. Results. There were significant differences in the means of marginal gaps in terms of prophylactic techniques (P < 0.001), with significantly larger marginal gaps in the APD group compared to the pumice and rubber cup group, which in turn exhibited significantly larger marginal gaps compared to the control group (P < 0.0005). In addition, the means of marginal gaps were significant in terms of the margin type (P < 0.001), with significantly larger gaps at gingival margins compared to the occlusal margins (P < 0.0005). Conclusion. The prophylactic techniques used in this study had a negative effect on the marginal gaps of Cl V resin-modified glass-ionomer restorations.

The study aimed to determine if the addition of daily low-dose oral estrogen with a cyclical progestogen given to young women using a depot gonadotropin-releasing hormone (GnRH) analog implant for the treatment of their premenstrual syndrome (PMS) would affect the clinical outcome. In a double-blind placebo-controlled study in a specialist premenstrual syndrome clinic setting, 60 women aged between 20 and 45 years were randomized to one of three treatment groups: Group A (placebo implant four weekly + placebo tablets daily), Group B (goserelin 3.6 mg implant four weekly + estradiol valerate 2 mg daily with norethisterone 5 mg from days 21-28 of a 28-day cycle) or Group C (goserelin 3.6 mg implant four weekly + placebo tablets daily). Differences between PMS scores at 2, 4 and 6 months were compared with pretreatment values. There was a significant improvement in PMS scores in Group C (Zoladex + placebo) after 2, 4 and 6 months of treatment when compared to pretreatment values and Group A (placebo + placebo). The addition of a low-dose oral estrogen with a cyclical progestogen to GnRH analog treatment (Group B) resulted in a less dramatic response when compared to pretreatment values and no significant improvement when compared to Group A (placebo + placebo) at 2, 4 and 6 months of treatment. The addition of a low-dose oral estrogen with a cyclical progestogen to depot GnRH analog therapy in the treatment of PMS reduces the clinical response.

After an acute myocardial infarction (MI), neurohumoral systems including renin-angiotensin-aldosterone system (RAAS) are activated which in turn aggravate cardiac remodeling. Angiotensin receptor blockers (ARBs) are useful drugs for suppression of RAAS. The purpose of this study was to evaluate a new ARB, azilsartan, for suppressing cardiac remodeling and progression to heart failure after MI. We created MI by left anterior descending coronary artery ligation in male mice, and these mice were orally administered saline (0.2 mL) in the control group (Group C), 0.1 mg/kg/d of azilsartan in the low dose group (Group L), and 1.0 mg/kg/d in the high dose group (Group H) everyday. Blood pressure was decreased in Group H, but not in Group L, compared to Group C. At 2 weeks after MI creation, infarct size and fibrotic change at the site remote to the myocardial infarcted area were attenuated in Group L and Group H compared to Group C. Echocardiography revealed that cardiac remodeling was suppressed in Group L and Group H compared to Group C. Increases of mRNA expression levels related to fibrotic change were attenuated in Group L and Group H compared to Group C. The new ARB, azilsartan, had a cardiac remodeling suppression effect after MI, and this effect was observed without blood pressure lowering.

OBJECTIVE: To measure the prevalence of posttraumatic stress disorder and emotional distress among victims of the Saguenay flood compared with those who were not affected by the flood. DESIGN: Cross-sectional study using a telephone survey of victims and a control group. SETTING: Chicoutimi, Que. PARTICIPANTS: Sixty-two adults in a flooded area and a control group of 79 volunteers chosen randomly from an adjacent area. MAIN OUTCOME MEASURES: Diagnostic criteria for posttraumatic stress disorder measured using the Post-traumatic Stress Disorder Reaction Index and high scores on the Self-Reporting Questionnaire on emotional distress. RESULTS: Socially and demographically, study group and control group were comparable. Prevalence of posttraumatic stress disorder in the study group was close to 20% (odds ratio [OR] 6.08; 95% confidence interval [CI] 1.63 to 22.64). Prevalence of emotional distress in the study group was 29% (OR 2.42; 95% CI 1.04 to 5.61). CONCLUSION: The Saguenay flood caused psychological distress that was measurable 4 months later. Health care professionals should be aware of the psychological effects of natural disasters. PMID:11153409

Objective To measure the efficacy of protection orders (POs) in reducing assault and injury-related outcomes using a matched comparison group and tracking outcomes over time. Methods This study was a retrospective review of police, emergency department, family court and prosecutor administrative records for a cohort of police-involved female IPV victims; all events over a four-year study period were abstracted. Victims who obtained protection orders (POs) were compared to a propensity-score-based match group without POs over three time periods: Before, during, and after the issuance of a PO. Results Having a PO in place was associated with significantly more calls to police for non-assaultive incidents, and more police charging requests that were multiple-count and felony-level. Comparing outcomes, PO victims had police incident rates that were more than double the matched group prior to the PO, but dropped to the level of the matched group during and after the order. ED visits dropped over time for both groups. Conclusion This study confirmed the protective effect of POs, which are associated with reduced police incidents and emergency department visits both during and after the order, and reduced police incidents compared to a matched comparison group.

The purpose of this study was to estimate the caloric intake and fat consumption in children with celiac disease (CD) following a gluten-free diet (GFD). This study enrolled 100 subjects, including 50 children with CD on a gluten-free diet and a control group of 50 healthy children. Statistical analysis to compare groups was performed using one-way ANOVA. A significant increase in fat consumption was observed in children with CD as compared to healthy children. The daily fat intake was 72.5 +/- 37.2 g per 100 g of food in the CD group and 52.9 +/- 35.4 g per 100 g of food in the control group (p < 0.008). A significant difference in fat intake was found between celiac and healthy females (10.21 +/- 3.15 g/100 g in the celiac group vs 7.46 +/- 2.91 g/100 g in the control group), p = 0.004. This study describes a significantly higher fat consumption in patients with CD on GFD as compared to controls. This increase was more pronounced in females and during the puberal age. Based on these interesting preliminary results we estimate that further investigations are necessary, such as a randomized multicentre study on the long-term effects of GFD with particular attention to the imbalance in daily fat intake.

Urinary Incontinence (UI) in women is a condition that becomes more common with age. Pelvic floor muscle training (PFMT) is recommended as a first option of treatment for women with symptoms of stress urinary incontinence (SUI), mixed urinary incontinence (MUI), and for some with symptoms of urge urinary incontinence (UUI). PFMT can be performed in groups, individually, and at home, and there is no consensus as to which of the approaches is more efficient for the conservative treatment of UI. The objective was to perform a systematic review comparing the effects of group PFMT vs individual or home training in the treatment of women with UI. Cochrane's recommendations for systematic reviews were followed. The inclusion criteria were that the studies had been carried out in adult women who suffered from UI and who underwent PFMT in a group. Ten studies that fit the criteria previously mentioned were included in this systematic review. The meta-analysis showed that there was no difference when comparing PFMT in groups vs individual PFMT. However, when comparing PFMT in groups vs PFMT at home, the group intervention was more efficient in the treatment of UI. PFMT is an efficient technique for the improvement of the symptoms of female UI. When PFMT was supervised by a physiotherapist, no significant difference was noted when comparing group with individual approaches.
