To investigate the efficacy of moxibustion in ulcerative colitis (UC) rats from morphological, immunological and molecular biological perspectives. Thirty-two Sprague-Dawley rats were randomly assigned to a blank control group (normal rats, n = 6) and a model replication (MR) group (UC rats, n = 26). A UC model was established by 2,4,6-trinitrobenzenesulfonic acid/dextran sulfate sodium enema. Rats in the MR group were further randomly assigned to a 9-min moxibustion (9M) group (9 moxa-cone, n = 6), 6-min moxibustion (6M) group (6 moxa-cone, n = 6), 3-min moxibustion (3M) group (3 moxa-cone, n = 6), and a waiting list control (WLC) group (no moxibustion treatment, n = 6). Rats in the moxibustion treatment group were treated in 14 sessions over 28 d. Disease activity, local tissue morphology, serum level of interleukin (IL)-8 and IL-10, and expression of Toll-like receptor (TLR)9 as well as nuclear factor (NF)-κB p65 in colonic tissue were determined by disease activity index (DAI), hematoxylin and eosin staining, electron microscopy, enzyme-linked immunosorbent assay and Western blotting, respectively. DAI was lowest in the 9M group and highest in the WLC group. The differences in DAI between the moxibustion treatment (3M, 6M, 9M) and no treatment groups were significant for all one-to-one comparisons (0.60 ± 0.54 vs 1.20 ± 0.44, 0.60 ± 0.54 vs 1.80 ± 0.45, 0.60 ± 0.54 vs 3.0 ± 0.45, respectively, P < 0.05). Light and electron microscopy showed that the neatness of the glandular arrangement in colonic mucosal epithelia gradually increased in the WLC, 3M, 6M to 9M groups. IL-8 level successively decreased while IL-10 level increased from the WLC to 3M, 6M and 9M groups. The differences among these groups were significant for all comparisons (105.46 ± 8.75 vs 76.61 ± 3.58, 105.46 ± 8.75 vs 69.78 ± 1.87, 105.46 ± 8.75 vs 67.41 ± 1.84, respectively, P < 0.01 for IL-8; and 30.83 ± 1.29 vs 75.64 ± 1.90, 30.83 ± 1.29 vs 80.90 ± 3.16, 30.83 ± 1.29 vs 83.46 ± 2.37, respectively, P < 0.01 for IL-10), except comparison of 6M vs 9M. Expression of TLR9 and NF-κB p65 decreased in order: highest in the WLC group and lowest in the 9M group. In addition, the differences among the WLC, 3M, 6M and 9M groups were significant for all comparisons (0.492 ± 0.026 vs 0.380 ± 0.022, 0.492 ± 0.026 vs 0.355 ± 0.005, 0.492 ± 0.026 vs 0.327 ± 0.015, respectively, P < 0.05 for TLR9; and 0.436 ± 0.041 vs 0.326 ± 0.022, 0.436 ± 0.041 vs 0.293 ± 0.006, 0.436 ± 0.041 vs 0.265 ± 0.017, respectively, P < 0.05 for NF-κB p65). Moxibustion repairs damaged colonic mucosa, suppresses serum IL-8, activates serum IL-10 level, and decreases expression of TLR-9 and NF-κB p65 in UC rats.

A retrospective analysis evaluated the effectiveness of an insurance carrier's flexible loss control service strategy in reducing workers' compensation policyholders' reported injury and illness claims. To assess the effects of a loss control service strategy on workers' compensation claim frequency rates, on medical-only claim rates, on severity-claim rates, and on claim cost among a group of California employers. Eighty-two small- and medium-sized companies with workers' compensation policies expiring in 1999 were randomly selected from a population of policyholders assigned to loss control consultants for two or more years. Claim performance data were obtained for each company's first expired in-force policy year and its 1999 expired policy year. The retrospective design was combined with a control component based on a randomly selected comparison group of 45 companies whose first policy year with the insurer expired in 1999 and who received safety services from the loss control staff. The flexible loss control consultation service strategy was associated with lower average claim rates and costs. Companies assigned to a loss control consultant for two or more years (the "outcome group") had an average claim rate of 1.24 per $10,000 premium, compared with a rate of 1.62 in the "initial group" and a rate of 1.60 in the "comparison group." The average severity-claim rate of the outcome group was 0.32, compared with the initial-year and comparison-group means of 0.48 and 0.46, respectively. The average medical-only claim rate was 0.92, compared with the initial- and comparison-group means of 1.14 and 1.14. The outcome group's average loss ratio was over 10% lower than that of the initial and comparison groups. Statistical analysis indicated that differences among the groups' claim rates and severity-claim rates were [F=(2,206) 4.938, P=0.008] and [F=(2,206) 8.208, P<0.001], respectively. A loss control service strategy that provides service flexibility and develops partnership between employer and consultant can help reduce the frequency and severity of workers' compensation claims. Barriers to consultation service flexibility, both internal and external, should be identified and removed to enhance service efficacy.

Uskokovic, Lila Milica

This study compared maternal lifestyle variables pertinent to the perinatal period in groups of chemically dependent mothers and drug-free mothers. Twenty-nine cocaine -abusing mothers were compared to 29 drug-free mothers carefully matched on age, race, education, and primipara versus multipara status. The drug history of each chemically dependent woman was explicitly documented. The chemically dependent group was subdivided into two groups, mothers who abused cocaine and those who abused cocaine with concomitant opiate use. Each of these two subgroups was compared to its respective matched drug-free control group. Finally, a comparison was made between the two drug subgroups. All subjects were interviewed within 48 hours after delivery using the following measures: State-Trait Anxiety Inventory (A-State), Center for Epidemiologic Studies - Depression Scale, The Self-Esteem Scale, Maternal Adjustment and Maternal Attitude Questionnaire, The Neonatal Perception Inventory, The Psychiatric Epidemiology Research Interview Life Events Scale, Maternal Social Support Index, and Short Marital Adjustment Test. A t-test analysis revealed significant differences (p <.05) between the total experimental group and its matched control group on state anxiety, depression, self-esteem, maternal adjustment and attitudes, and life events. An analysis of covariance indicated that life events was the only significant variable when the influence of all other variables was removed. Comparisons made between each drug subgroup and its respective matched control group showed similar results, except that those who abused opiates with cocaine did not differ from their controls on depression and maternal adjustment and attitudes. No significant differences were obtained in the drug subgroup comparisons. These results identify increased life events and specific negative affect states that clinical intervention programs should address to assure the best possible outcome for chemically dependent mothers and their infants.

AIM To compare recovery of the visual acuity in patients one day after sub-Bowman keratomileusis (SBK) or laser in situ keratomileusis (LASIK). METHODS Data from 5923 eyes in 2968 patients that received LASIK (2755 eyes) or SBK (3168 eyes) were retrospectively analyzed. The eyes were divided into 4 groups according to preoperative spherical equivalent: between -12.00 to -9.00 D, extremely high myopia (n=396, including 192 and 204 in SBK and LASIK groups, respectively); -9.00 to -6.00 D, high myopia (n=1822, including 991 and 831 in SBK and LASIK groups, respectively), -6.00 to -3.00 D, moderate myopia (n=3071, including 1658 and 1413 in SBK and LASIK groups, respectively), and -3.00 to 0.00 D, low myopia (n=634, including 327 and 307 in SBK and LASIK groups, respectively). Uncorrected logMAR visual acuity values of patients were assessed under standard natural light. Analysis of variance was used for comparisons among different groups. RESULTS Uncorrected visual acuity values were 0.0115±0.1051 and 0.0466±0.1477 at day 1 after operation for patients receiving SBK and LASIK, respectively (P<0.01); visual acuity values of 0.1854±0.1842, 0.0615±0.1326, -0.0033±0.0978, and -0.0164±0.0972 were obtained for patients in the extremely high, high, moderate, and low myopia groups, respectively (P<0.01). In addition, significant differences in visual acuity at day 1 after operation were found between patients receiving SBK and LASIK in each myopia subgroup. CONCLUSION Compared with LASIK, SBK is safer and more effective, with faster recovery. Therefore, SBK is more likely to be accepted by patients than LASIK for better uncorrected visual acuity the day following operation. PMID:27158619

BACKGROUND Hypothyroid has several effects on the cardiovascular system. Global myocardial performance index (MPI) is used in assessment of both left ventricular (LV) systolic and diastolic function. We compared MPI in hypothyroidism patients vs. normal control subjects. MATERIAL AND METHODS Eighty-two hypothyroid patients were divided into 2 groups: a subclinical hypothyroid (SH) group (n=50), and an overt hypothyroid (OH) group (n=32). The healthy control group (CG) constituted of 37 patients. TSH, FT3, and FT4, anti-TPO, anti-TG, insulin, lipid values, and fasting glucose levels were studied. All patients underwent an echocardiographic examination. Myocardial performance indexes were assessed and standard echocardiographic examinations were investigated. RESULTS MPI averages in OH, SH, and control groups were 0.53±0.06, 0.51±0.05, and 0.44±0.75 mm, respectively. MPI was increased in the OH and SH groups in comparison to CG (p<0.001, p<0.001, respectively). CONCLUSIONS MPI value was significantly higher in hypothyroid patients in comparison to the control group, showing that regression in global left ventricular functions is an important echocardiographic finding. Future studies are required to determine the effects of this finding on long-term cardiovascular outcomes.

To re-evaluate the effects of different "cocktail therapy" to prevent from phlebitis induced by Chansu injection. Patients treated with Chansu injection were divided randomLy into 4 groups with 90 per group, control group, phentolaminum group, the magnesium sulfate group-phentolaminum group, and anisodamine-phentolaminum group. Patients in the control group only received the routine nursing treatment, and patients in the various experiment group received different interventions. The comparison was made in the morbidity and the starting time of occurrence of phlebitis, the severity of pain, duration of pain. The morbidity of phlebitis was 8%, 8%, 6%, respectively. The starting time of phlebitis occurrence was (22 +/- 4), (27 +/- 5), (28 +/- 7) h, respectively. The NRS of pain was (4.75 +/- 1.51), (3.27 +/- 1.02), (2.71 +/- 1.63), respectively. The duration time of pain was (4.25 +/- 1.36), (2.51 +/- 1.05), (2.19 +/- 1.13) d respectively. In control group, the morbidity of phlebitis, the starting time of occurrence of phlebitis, the severity of pain, duration of pain was 30%, (16 +/- 4) h, (6.34 +/- 1.21), (5.47 +/- 1.07) d, respectively. As compared with the control group, a significance difference was found between every group in three test groups and control group respectively (P<0.05). The morbidity and the starting time of occurrence of phlebitis, the severity of pain, duration of pain was significantly reduced respectively by two different "cocktail therapy".

The comparison of specific gravity values of 561 urine samples from TS meter and reagent strip was made. The data were divided into two groups: group 1-less than 2+ protein contained urine samples and group 2--equal or more than 2+ protein contained urine samples. The results revealed that the specific gravity values from both methods in both groups were statistically different (p less than 0.01) but they were correlated at r = 0.84 (p less than 0.001) and r = 0.73 (p less than 0.001) in group 1 and group 2, respectively. It was concluded that the reagent strip is suitable for use as a screening test but it should not be considered when precise measurement is necessary.

The NREL Pyrheliometer Comparisons for 2012 (NPC-2012) were held at the Solar Radiation Research Laboratory in Golden, Colorado, from September 24 through October 5 for the purpose of transferring the World Radiometric Reference (WRR) to participating instrument. Twenty scientists and engineers operated 32 absolute cavity radiometers and 18 conventional thermopile-based pyrheliometers to simultaneously measure clear-sky direct normal irradiance during the comparisons. The transfer standard group of reference radiometers for NPC-2012 consisted of four NREL radiometers with direct traceability to the WRR, having participated in the Eleventh International Pyrheliometer Comparisons (IPC-XI) hosted by the World Radiation Center in the fall ofmore » 2010. As the result of NPC-2012, each participating absolute cavity radiometer was assigned a new WRR transfer factor, computed as the reference irradiance computed by the transfer standard group divided by the observed irradiance from the participating radiometer. The performance of the transfer standard group during NPC-2012 was consistent with previous comparisons, including IPC-XI. The measurement performance of the transfer standard group allowed the transfer of the WRR to each participating radiometer with an estimated uncertainty of +/- 0.33% with respect to the International System of Units.« less

[Purpose] This study aims to identify the immediate effects of taping therapy on knee pain and depression among patients with degenerative arthritis. [Subjects and Methods] In total, 32 patients with degenerative arthritis were randomly assigned to one of two groups: the experimental group that underwent taping therapy and the control group that underwent regular treatment (16 patients per group). In the experimental group, therapeutic tape was wrapped all around the knee joint. Pain and depression were measured using the visual analogue scale (VAS) and the Beck Depression Inventory (BDI), respectively. [Results] The intra-group comparison showed significant differences in VAS and BDI for the experimental group. The intergroup comparison showed that the differences in VAS and BDI within the experimental group appeared significant relative to the control group. [Conclusion] It was observed that taping therapy showed an immediate effect in decreasing knee pain and depression among patients with degenerative arthritis.

Bacoside rich juice (BRJ) was developed using date syrup as base. BRJ was evaluated for physicochemical, sensory attributes and its effect on physical endurance. Overall acceptability of BRJ and date syrup juice (DSJ) was good according to hedonic scale/ratings. Twenty four adult male Wistar rats were divided into 4 groups (n = 6). Sedentary (Group I) and control (Group II) group rats were allowed to drink water whereas DSJ and BRJ group rats were provided free access to drink DSJ (Group III) and BRJ (Group IV) for 14 days and were subjected to weight-loaded forced swim test (WFST) for every alternate day in order to evaluate the physical endurance. Both BRJ and DSJ group rats swimming efficiency was improved by 3 and 2 folds respectively in comparison with control group on day- 15. Improved physical endurance in BRJ group is due to reduced malondialdehyde levels in brain, liver and muscle tissues by 16.50 %, 17.88 % and 30.20 %, respectively, compared to DSJ group (p < 0.01). In addition, administration of BRJ significantly protected the hepatic and muscle glycogen levels and reduced the levels of lactic acid in comparison to DSJ group. Hence, the present study clearly indicates that BRJ is an effective anti-fatigue drink ameliorates the various impairments associated with physical endurance.

The purpose of this study was to observe exercise training–induced effects on adiponectin, leptin, and ghrelin. Twenty-nine older, healthy participants were classified as physically active (comparison group: N = 15, 70.9±1.2 years) or physically inactive (exercise group: N = 14, 70.5±1.4 years). Exercise group participants completed 12 weeks of combined aerobic and resistance exercise training, whereas comparison group participants maintained their current level of exercise and served as a physically active comparison group. Monocyte phenotype, as well as serum ghrelin, leptin, adiponectin, and soluble tumor necrosis factor receptor II were analyzed prior to and following the 12-week period. Ghrelin and adiponectin increased 47% and 55%, respectively, in exercise group participants following exercise training. Percent change in ghrelin (post and pre) was negatively correlated with the percent change in CD14+CD16+ monocytes (post and pre) in exercise group participants. Despite no changes in body mass, these data contribute to evidence for the anti-inflammatory effects of exercise. PMID:24013674

What happens if we compare chopsticks with forks? The impact of making inappropriate comparisons in cross-cultural research.

It is a common practice to export instruments developed in one culture to another. Little is known about the consequences of making inappropriate comparisons in cross-cultural research. Several studies were conducted to fill in this gap. Study 1 examined the impact of lacking factor loading invariance on regression slope comparisons. When factor loadings of a predictor are higher in the reference group (e.g., United States), for which the scale was developed, than in the focal group (e.g., China), into which the scale was imported, the predictive relationship (e.g., self-esteem predicting life satisfaction) is artificially stronger in the reference group but weaker in the focal group, creating a bogus interaction effect of predictor by group (e.g., self-esteem by culture); the opposite pattern is found when the reference group has higher loadings in an outcome variable. Studies 2 and 3 examined the impact of lacking loading and intercept (i.e., point of origin) invariance on factor means, respectively. When the reference group has higher loadings or intercepts, the mean is overestimated in that group but underestimated in the focal group, resulting in a pseudo group difference.

Although effective community falls prevention programmes for the older persons have been described, challenges remain in translating proven interventions into daily practice. To evaluate the efficacy, feasibility and acceptability of a falls prevention programme that can be integrated into daily activities in a group of community-dwelling older adults with risk of falling. A cohort study with intervention and comparison groups was designed to evaluate a 36-week group-based falls prevention exercise programme (FaME) in the community setting. Participants were aged 60 years or older, had fallen in the past 12 months, had fear of falling with avoidance of activities or had deficits in balance control. Primary outcome measures included assessment of balance control and mobility; secondary outcome measures included level of physical activity, assessment of fear of falling and health-related quality of life. There were 48 and 51 participants in the intervention and comparison groups, respectively. There were improvements in measurements of balance, walking speed and self-efficacy. The drop out rate was low (14.6% and 3.9% from the intervention and comparison groups, respectively). Overall compliance in the intervention group was 79%. Factors that motivated continued participation include the regular and long-term nature of the programme helping to reinforce their exercise habits, the simplicity of movements and friendliness of the group. The FaME programme improves balance, walking speed and reduces fear of falling. It could be widely promoted and integrated into regular health and social activities in community settings.

Are there any radiological criterions which are able to indicate the profession related disease No. 2108? The medical documents and x-rays of the whole spine of 390 back pain patients who applied for a profession related disease of the spine were evaluated. Those patients who fulfilled the professional claims for acknowledgement of the profession related disease were compared to those who didn't fulfill these conditions. Concerning the segmental alterations of the cervical and the lumbal spine specific allocation frequencies were found. The dominance of L3/4 in the comparison group was conspicuous. Looking at the allocation frequencies of the cervical and lumbal disc alterations in view of affection heaviness it was obvious, that the predominating slight alterations mainly were located in the central parts of the cervical and the lumbal spine whereas bad alterations mainly were found in the lower parts. Regarding this matter test and comparison groups behaved the same way. Looking at the allocation frequencies concerning single respectively multiple alterations it was found that in the comparison group single respectively bisegmentale alterations could be recognized even in duplicate than in the test group in which the multiple alterations were dominant. The comparison of the cervical and the lumbal spine regarding chondrotic? spondylotic, slight and bad alterations in all mentioned features the next deeper located segment was affected particularly in the test group. Therefore a distal shift of the chondrotic alterations could be recognized. In case of the spondylotic affections it was the other way round: a cranial shift was conspicuous. After doing heavy labour for years only a few isolated multiple affections of the lumbal spine are found. On the strength of this fact the proof of exclusively in the lumbal spine located alterations doesn't allow the acknowledgement of a profession related disease. However, a distal shift of osteochondrotic alterations respectively a cranial shift of spondylotic affections in the lumbal spine is suspicous for being job-related. L3/4 takes a very special place in the differential diagnosis of profession related disease of the spine. In the test group this part of the lumbal spine showed bad alterations much more frequent. The affection of L3/4 pleads against a considerable participation of mechanical influences and therefore against a profession related disease. Singular or bisegmental disc affections are out of question for being a profession related disease because these alterations are seen much more frequent in the comparison than in the test group.

Long-term morbidities can develop after traumatic brain injury (TBI). Some studies have suggested that the risk of stroke is higher after TBI, but the association between concussion and stroke remains unclear. Using a national cohort, the authors analyzed the incidence of both hemorrhagic and ischemic strokes in patients with previous concussion. A representative cohort of approximately one million people was followed up for four years. Patients with new-onset concussion were identified ( n = 13,652) as the concussion group. Subsequently, the incidence rates of later stroke events in the concussion group were compared to a sex-, age- and propensity score-matched comparison group ( n = 13,652). The overall incidence rate of stroke in the concussion group was higher than that of the comparison group (9.63 versus 6.52 per 1000 person-years, p < 0.001). Significantly higher stroke risk was observed in the concussion group than in the comparison group (crude hazard ratio 1.48, p < 0.001; adjusted HR 1.65, p < 0.001). In the concussion group, the cumulative incidence rates of both ischemic stroke and hemorrhagic stroke were higher than those of the comparison group (8.9% vs. 5.8% and 2.7% vs. 1.6%, respectively, both p < 0.001). Concussion is an independent risk factor for both ischemic and hemorrhagic strokes. Prevention and monitoring strategies of stroke are therefore suggested for patients who have experienced concussion.

Forty-four dogs with multicentric lymphoma were treated using a cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) induction protocol or treated using a cyclophosphamide, mitoxantrone, vincristine, and prednisolone (CMOP) induction protocol. There was no statistical difference in signalment and the presence of historical negative prognostic factors between the groups. The median progression-free survival (PFS) in the CHOP and CMOP groups were 222 d and 162 d, respectively (P = 0.75). The median survival time (MST) of dogs in CHOP and CMOP groups were 318 d and 242 d, respectively (P = 0.63). Anorexia and diarrhea episodes were significantly higher in the CHOP group than in the CMOP group (P = 0.02 and P = 0.01, respectively). These results suggest that the CMOP protocol provides similar PFS, MST and causes fewer side effects compared to the CHOP protocol. Therefore, the CMOP protocol may be another treatment choice for canine multicentric lymphoma. PMID:26933263

To analyze the dietary factors on sarcopenia in elderly in Beijing and provide nutritional recommendations for the sarcopenia. A total of 830 participants aged 60 and above and without serious diseases were selected from two representative communities in Beijing. A cross-sectional research design was used, including inquiry investigation, dietary surveys (food frequency questionnaire) anthropometry, muscle mass and functional assessment. The prevalence of sarcopenia was 20.1% in this area, the men was 17.1%, while the women was 21.6% (P > 0.05). The prevalence of sarcopenia in the five age groups has significant statistically difference (chi2 = 19.03, P = 0.0008) and increased with age rising (Z = -4.18, P < 0.0001). The prevalence of sarcopenia would be downward if the time of exercise prolonged and body mass index (BMI) increased (P < 0.05). The prevalence of sarcopenia in the group of meat consumption <35, 35-70, > 70 g/d was 24.5%,19.9% and 15. 3% (chi2 = 6.02, P = 0.0492), respectively (trend test for groups comparison, Z = 2.45, P =0.0141). The prevalence of sarcopenia in the group of egg consumption <35, 35-60, >60 g/d was 25.8%, 18.7% and 11.3% (chi2 = 6.50, P = 0.0388), respectively ( trend test for groups comparison, Z =2. 55, P = 0.0109). The prevalence of sarcopenia in the group of energy consumption < 1612, 1612-2109, > 2109 kcal/d was 25.8%,19.5% and 15. 0% (x2 = 8. 19 , P = 0. 0158), respectively (trend test for groups comparison, Z = 2.87, P = 0.0042). The prevalence of sarcopenia in the group of protein consumption < 58.2, 58.2 - 78.4, > 78.4 g/d was 25.3%, 18.2% and 16.7% (chi2 = 5.97, P = 0. 0505 ) , respectively (Z = 2.28, P = 0.0227). After controlling the influence of age, BMI, exercise and education, meat consumption (beta = -0.1703, P = 0.0119), egg consumption (beta = -0.1545, P = 0.0302) and the high quality protein consumption (beta = -0.1805, P = 0.0302) were negatively related with sarcopenia. Animal food, such as meet and egg, is an important protective factor for sarcopenia. Therefore, it is the first important thing for the elderly to ensure adequate energy intake, then you should increase the animal food intake which contains high quality protein to prevent sarcopenia.

Coaches are a major source of nutrition information and influence for young athletes. Yet, most coaches do not have training in nutrition to properly guide their athletes. The aim of this study was to evaluate the effectiveness of an intervention aimed at improving the accuracy of coaches' recommendations on sports nutrition. This was a quasi-experimental study with a comparison group and an intervention group. Measurements were made at baseline, post-intervention, and after a 2-month follow-up period. Coaches' recommendations on sports nutrition during the follow-up period were recorded in a diary. High school coaches from various sports (n=41) were randomly assigned to a comparison group or an intervention group. Both groups attended two 90-minute sessions of a theory-based intervention targeting determinants of coaches' intention to provide recommendations on sports nutrition. The intervention group further received an algorithm that summarizes sports nutrition guidelines to help promote decision making on sports nutrition recommendations. Nutrition knowledge and accuracy of coaches' recommendations on sports nutrition. χ(2) analyses and t-tests were used to compare baseline characteristics; mixed and general linear model analyses were used to assess the change in response to the intervention and differences in behaviors, respectively. Coaches in the intervention vs comparison group provided more nutrition recommendations during the 2-month post-intervention period (mean number of recommendations per coach 25.7±22.0 vs 9.4±6.5, respectively; P=0.004) and recommendations had a greater accuracy (mean number of accurate recommendations per coach 22.4±19.9 [87.1%] vs 4.3±3.2 [46.1%], respectively; P<0.001). Knowledge was significantly increased post-intervention in both groups, but was maintained only in the intervention group during the 2-month follow-up (Pgroup*time=0.04). A theory-based intervention combined with a decision-making algorithm maintained coaches' sports nutrition knowledge level over time and helped them to provide more accurate recommendations on sports nutrition.

To determine whether semen and plasma presepsin values measured in men with normozoospermia and oligoasthenospermia undergoing invitro-fertilization would be helpful in predicting ongoing pregnancy and live birth. Group-I was defined as patients who had pregnancy after treatment and Group-II comprised those with no pregnancy. Semen and blood presepsin values were subsequently compared between the groups. Parametric comparisons were performed using Student's t-test, and non-parametric comparisons were conducted using the Mann-Whitney U test. There were 42 patients in Group-I and 72 in Group-II. In the context of successful pregnancy and live birth, semen presepsin values were statistically significantly higher in Group-I than in Group-II (p= 0.004 and p= 0.037, respectively). The most appropriate semen presepsin cut-off value for predicting both ongoing pregnancy and live birth was calculated as 199 pg/mL. Accordingly, their sensitivity was 64.5% to 59.3%, their specificity was 57.0% to 54.2%, and their positive predictive value was 37.0% to 29.6%, respectively; their negative predictive value was 80.4% in both instances. Semen presepsin values could be a new marker that may enable the prediction of successful pregnancy and/or live birth. Its negative predictive values are especially high.

to examine the effect of individual counselling on diet and physical activity from pregnancy to six months post partum, or from birth to six months post partum, on weight retention among Taiwanese women. a randomised controlled trial assigned participants to two experimental groups [from pregnancy to six months post partum (EP) and from birth to six months post partum (EPP)] and one comparison group. a 3900-bed medical centre in northern Taiwan with around 3000 births annually. a sample of 189 women who had regular check-ups during pregnancy and gave birth at the medical centre. the comparison group received the routine outpatient department obstetric educational programme. The EP group attended regularly scheduled clinic visits with individualised dietary and physical activity education plans from 16 gestational weeks to six months post partum, and received on brochure. The EPP group received the same educational intervention as the EP group from 24-48 hours after birth to six months post partum. body weight, body mass index, health-promoting behaviour and psycho-social variables (self-efficacy, body image, depression and social support). average gestational weight gain was 14.02, 15.27 and 16.22 kg in the three EP, EPP and comparison groups respectively, and average weight retention at six months post partum was 2.34, 4.06 and 5.08 kg in the three groups, respectively. a diet and physical activity intervention from pregnancy is effective for reducing post-pregnancy weight retention. the findings of the present study should be taken into consideration when incorporating significant others and weight-loss maintenance strategies with interventions for a healthier family lifestyle.

The aim of this study was to compare the morphology of the bronchial stump after lobectomy between mechanical stapler closure and manual suture closure. The effect of fibrin glue application on each method of closure was also observed. Right upper lobectomy was performed in beagles (n=31) using staplers (ST group) or sutures (SU group). In a separate experiment, fibrin glue was sprayed onto the stump after each respective method of closure. After one week, the stump region was examined macroscopically, and also by histology. chi(2)-Test and Mann-Whitney test were used for comparative analysis. The incidence of adhesion formation between the surrounding tissues was significantly reduced in the ST group in comparison to the SU group (22 vs. 80%, P=0.04). The thickness of granulation tissue over the stump was significantly reduced in the ST group in comparison to the SU group (0.8+/-0.2 vs. 2.5+/-0.3 mm, P<0.0001). Vessel density in the granulation tissue was also significantly reduced in the ST group in comparison to the SU group (6+/-2 vs. 16+/-2, P=0.003). Fibrin glue application after stapler closure significantly increased the incidence of adhesion formation, granulation tissue thickness, and vessel density in the granulation tissue over the stump.

The paper compares several generational groups of Turkish children in Germany with respect to cognitive skills and German language skills at an early age. Empirically, children of inter-marriages outperform the other groups of Turkish children in both tests while children with a first generation mother and a second generation father score worse than all others. All group differences regarding children’s cognitive skills can be explained by the families’ socio-economic status and educational resources. In contrast, with respect to children’s language skills also parents’ endowment with receiving country specific resources (e.g., parental German language proficiency) needs to be taken into account.

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.

The objective of this study was to compare and evaluate the effects of two functional treatment modalities, namely, Twin Block (TB) and FORSUS fatigue resistant device (FORSUS FRD) on facial soft tissues before and at one-year post-treatment. This was a retrospective cephalometric study involving 10 patients with skeletal class II abnormalities in each group. The mean age of patients was 12.5 ± 1.5 and 13.5 ± 1 years and treatment duration 20 ± 2 and 18 ± 2 months, respectively for TB and FORSUS FRD groups, respectively. The pre-treatment (T0) and one-year post-treatment cephalograms (T1) were compared for evaluation. Data were analysed using a paired t -test and independent sample t -test for within-group and between-group comparisons, respectively. The groups were compared at T0 and T1, and treatment/observation differences (T1 - T0) were evaluated with paired samples t -test at P  < 0.05 level and unpaired sample t -test for group comparison. Statistically significant treatment changes were found for soft tissue changes in both TB and FORSUS FRD groups. Between the two groups, TB showed significant increase in the LAFH compared to the FORSUS FRD group. Statistically significant soft tissue changes were observed after TB and FORSUS FRD appliance therapy, resulting in improvement of facial balance and aesthetics. Both, TB and FORSUS FRD, have similar effects on soft tissues, but the effect of TB on LAFH and that of FORSUS on mentolabial sulcus was more profound.

Introduction: Stevia (S. rebaudiana) a herb which has medicinal value and was used in ancient times as a remedy for a great diversity of ailments and sweetener. Leaves of Stevia contain a high concentration of Stevioside and Rebaudioside which are supposed to be sweetening agents. Aim: To compare the efficacy of aqueous and alcoholic S. rebaudiana extract against Streptococcus mutans and Lactobacillus acidophilus in comparison to chlorhexidine. Materials and Methods: In the first part of the study, various concentrations of aqueous and ethanolic Stevia extract were prepared in the laboratory of Pharmacy College. It was then subjected to microbiological assay to determine its zone of inhibition using Agar disk diffusion test and minimum inhibitory concentration (MIC) using serial broth dilution method against Streptococcus mutans and Lactobacillus acidophilus. Chlorhexidine was used as a positive control. One way Analysis of Variance (ANOVA) test was used for multiple group comparisons followed by Tukey post hoc for group wise comparisons. Results: Minimum inhibitory concentration (MIC) of aqueous and ethnolic Stevia extract against Streptococcus mutans and Lactobacillus acidophilus were 25% and 12.5% respectively. Mean zone of inhibition of the aqueous and alcoholic Stevia extracts against Streptococcus mutans at 48 hours were 22.8 mm and 26.7 mm respectively. Mean zone of inhibition of the aqueous and alcoholic Stevia extracts against Lactobacillus acidophilus at 48 hours were 14.4 mm and 15.1 mm respectively. Mean zone of inhibition of the chlorhexidine against Streptococcus mutans and Lactobacillus acidophilus at 48 hours was 20.5 and 13.2 respectively. Conclusion: The inhibitory effect shown by alcoholic Stevia extract against Streptococcus mutans and Lactobacillus acidophilus was superior when compared with that of aqueous form and was inferior when compared with Chlorhexidine.

This present study was conducted to analyze the volumetric change in the root canal space and instrumentation time between hand files, hand files in reciprocating motion, and three rotary files in primary molars. One hundred primary mandibular molars were randomly allotted to one of the five groups. Instrumentation was done using Group I; nickel-titanium (Ni-Ti) hand file, Group II; Ni-Ti hand files in reciprocating motion, Group III; Race rotary files, Group IV; prodesign pediatric rotary files, and Group V; ProTaper rotary files. The mean volumetric changes were assessed using pre- and post-operative spiral computed tomography scans. Instrumentation time was recorded. Statistical analysis to access intergroup comparison for mean canal volume and instrumentation time was done using Bonferroni-adjusted Mann-Whitney test and Mann-Whitney test, respectively. Intergroup comparison of mean canal volume showed statistically significant difference between Groups II versus IV, Groups III versus V, and Groups IV versus V. Intergroup comparison of mean instrumentation time showed statistically significant difference among all the groups except Groups IV versus V. Among the various instrumentation techniques available, rotary instrumentation is the considered to be the better instrumentation technique for canal preparation in primary teeth.

Left ventricular hypertrophy (LVH) has been proposed to be associated with an increased risk of stroke. We compared the prevalence of LVH among patients with first-ever ischemic versus first-ever hemorrhagic strokes. This observational study, which was conducted at the Sulaimaniya general teaching hospital from November 2009 to March 2012, involved 100 consecutive patients with their first-ever stroke. Fifty patients had ischemic stroke while the rest (n = 50) developed hemorrhagic stroke. The presence of LVH was detected using transthoracic echocardiography and a comparison with respect to its prevalence between the 2 aforementioned groups was made. The mean age of patients in the hemorrhagic group was 61.7 +/- SD 11.2 years while in the ischemic group it was 63.9 +/- SD 6.1 years. Out of 100 patients, 66 (66%) patients were males (31 in the hemorrhagic group and 35 in the ischemic group) while the rest (n = 34; 34%) were females (19 in the hemorrhagic group and 15 in the ischemic one). Ninety one (91%) patients were hypertensive (47 in the hemorrhagic group and 34 in the ischemic group). Fifty three (53%) out of 100 patients demonstrated LVH (31 in the hemorrhagic group and 22 in the ischemic group). A head-to-head comparison between the two groups with respect to gender demonstrated no statistically significant difference in terms of the presence of LVH among patients with hemorrhagic versus ischemic strokes; males (P value < 0.26; 95% CI 3.4-39.3); females (P value < 0.43; 95% CI 16.7-43.8). However, a univariate analysis after correction for age and gender revealed a statistically significant difference between these groups (P-value < 0.001; 95% CI 2.7-46.2). LVH was more common in Kurdish patients with first-ever hemorrhagic stroke than in those who had sustained their first-ever ischemic stroke. Further analytic studies are required to clarify the prevalence of LVH in patients with ischemic stroke.

Transoral endoscopic thyroidectomy vestibular approach (TOETVA) provides excellent cosmetic results from its potential for scar-free operation. The procedure has been applied successfully for Graves' disease by the authors of this work and compared with the standard open cervical approach to evaluate its safety and outcomes. From January 2014 to November 2016, a total of 97 patients with Graves' disease were reviewed retrospectively. Open thyroidectomy (OT) and TOETVA were performed in 49 patients and 46 patients, respectively. For TOETVA, a three-port technique through the oral vestibule was utilized. The thyroidectomy was done endoscopically using conventional laparoscopic instruments and an ultrasonic device. Patient demographics and surgical variables, including operative time, blood loss, and complications, were investigated and compared. TOETVA was performed successfully in all 45 patients, although conversion to open surgery was deemed necessary in one patient. All patient characteristics for both groups were similar. Operative time was shorter for the OT group compared to the TOETVA group, which totaled 101.97±24.618 and 134.11±31.48 minutes, respectively (P<0.5). Blood loss was comparable for both groups. The visual analog scale (VAS) pain score for the TOETVA group was significantly lower than for the OT group on day 1 (2.08±1.53 vs . 4.57±1.35), day 2 (0.84±1.12 vs . 2.57±1.08) and day 3 (0.33±0.71 vs . 1.08±1.01) (P<0.05). Transient recurrent laryngeal nerve (RLN) palsy was found in four and two cases of TOETVA and OT group, respectively. Transient hypocalcemia was found in ten and seven cases of TOETVA and OT group, respectively. No other complications were observed. TOETVA is a feasible and safe treatment for Graves' disease in comparison to the standard open cervical approach. It is considered a viable alternative for patients who have been indicated for surgery with excellent cosmetic results.

Intrauterine insemination (IUI) is one of the most commonly performed procedure of assisted reproductive technology, for the treatment of infertility. Controlled ovarian hyperstimulation is an important first step while performing IUI. This study aims at establishing a relationship between stimulation protocol and pregnancy outcome following IUI. This is a retrospective study of 1001 cycles of IUI in which the patients were divided into two groups: Group A Clomiphene citrate (CC only) and Group B Clomiphene citrate and Gonadotropin or Gonadotropin alone(CC+GN OR GN alone). The primary outcome assessed was clinical pregnancy rates (CPRs), and the secondary outcomes were miscarriage rate (MR), multiple pregnancy rates (MPRs), follicle numbers and endometrial thickness (ET). Significantly, higher CPR was observed in Group B in comparison with Group A (14.55 vs. 7.82%; p  = 0.05). MR was much higher in Group A in comparison with Group B, (14.29 vs. 5.43%; p  = 0.94), but it was non-significant. The follicle number and the ET of the Group A versus Group B are (1.54 ± 0.69 vs. 1.90 ± 1.04; p  = 0.0003) and (8.56 ± 1.33 vs. 8.39 ± 1.29; p  = 0.1784), respectively; and for subgroups, Group B1 and Group B2 are 1.92 ± 0.99 versus 1.65 ± 0.92; p  = 0.0008 and 8.32 ± 1.27 vs. 8.69 ± 1.24; p  = 0.0004, respectively. GN, either alone or the combination with CC, gives a higher CPR and a lower abortion rate following IUI, thus increasing the multiple pregnancy rate.

Little is known about the changes in prevalence of dietary supplement use in pregnancy, postpartum, and in a comparison group of nonpregnant women. We conducted a secondary analysis of the Infant Feeding Practices II study. The purpose of this study is to report the prevalence of herbal or botanical and nonvitamin, nonmineral dietary supplement use by US women with respect to demographic, behavioral, and health factors. We compared pregnant and postpartum women to a comparison group of nonpregnant women who had not given birth in the past 12 months. Our main outcome was the prevalence of dietary supplements. Multiple logistic regression models were used to examine factors associated with herbal or botanical and nonvitamin, nonmineral dietary supplement use during reproductive age, pregnancy, and postpartum. The total sample included 1444 women assessed during the prenatal period, 1422 from the postpartum period, and 1517 women in a comparison group. In terms of herb or botanical use, 15% of the prenatal group, 16% of the postpartum group, and 22% of the comparison group reported using herbs or botanicals. The most frequently used nonvitamin, nonmineral supplement was omega-3 fatty acid. Among the total prenatal group and comparison group, women eating 5 or more servings of fruits or vegetables were less likely to report using herbs or botanicals. Women in the comparison group self-identifying as black were 4 times as likely to report using herbs or botanicals compared to participants self-identifying as white. In addition, women identifying as a race other than white were almost twice as likely to report herb or botanical use across all study groups. This is one of the rare studies that shows the changing prevalence of herbs or botanicals and nonvitamin, nonmineral dietary supplement use in women in the reproductive stage of their lives. © 2016 by the American College of Nurse-Midwives.

Relief of pain is very important goal intraoperatively and postoperatively. Neostigmine has been used successfully intrathecally with other agents such as clonidine and opioids for pain relief. This study aims to compare and evaluate the efficacy and safety of combining intrathecal (IT) neostigmine with IT clonidine and transdermal nitroglycerin (tNTG) patch for the relief of pain in patients after surgery. This was a randomized, prospective, and comparative study. In this study, recruited patients were randomly allocated into three groups. Groups I, II, and III received intrathecally 25 μg of neostigmine + 15 mg hyperbaric 0.5% bupivacaine, 25 μg of neostigmine + 25 μg clonidine + 15 mg hyperbaric 0.5% bupivacaine, and 25 μg of neostigmine + tNTG patch (3 cm × 5 cm, 5 mg/24 h) +15 mg hyperbaric 0.5% bupivacaine, respectively. Heart rate, mean arterial pressure, analgesic properties, and complications were assessed and compared among groups. Mean and standard deviation were calculated. Test of analysis between two groups was done by t -test and among three groups by ANOVA, then P value was calculated. Duration of analgesia was significantly longer in Group III in comparison to Group II (7.142 ± 1.81 vs. 4.408 ± 0.813 h) and was significantly longer in Group II in comparison to Group I (4.408 ± 0.813 vs. 2.583 ± 0.493 h). Analgesic requirement was significantly less in Group III in comparison to Group II (1.9 ± 0.76 vs. 2.5 ± 0.51) and was significantly less in Group II in comparison to Group I (2.5 ± 0.51 vs. 3.1 ± 0.48). Sedation score was found significantly high in Group II than other groups. Both IT clonidine and tNTG patch with bupivacaine + neostigmine spinal anesthesia were found effective in pain control. Results were found better with tNTG patch.

Saliva is a complex secretion that protects and lubricates the oral cavity. Various systemic diseases and their treatment alter the salivary gland function; one such disease is Autoimmune Thyroid Disease (AITD). AITD has been postulated to exert its hormonal influence on the salivary glands, leading to reduced salivary output. There's a paucity of literature, verifying the stated conjunction in human subjects. The aim was to investigate the salivary profile in AITD patients and its comparison with controls. Descriptive cross-sectional comparative study was conducted using convenience sampling method for screening the presence of thyroid disorders. Two groups comprising of 30 patients in each group diagnosed with autoimmune hypothyroiditis (n=30) and hyperthyroiditis (n=30) respectively and thirty healthy volunteers who were age and sex matched were included as controls. Saliva was collected and evaluated for Unstimulated Salivary Flow Rate (USSFR), pH and buffer capacity. ANOVA and Tukey post-hoc test was performed to find the statistical significance and for pairwise comparison. Statistically significant difference was observed between autoimmune hypothyroiditis, autoimmune hyperthyroiditis and control group with respect to USSFR (p<0.007), pH (p<0.001) and buffer capacity (p<0.001). On pairwise comparisons statistically significant difference was observed between autoimmune hypothyroiditis and autoimmune hyperthyroiditis with respect to controls. We conclude that significant involvement of salivary glands may occur in cases of AITD. Our study showed significant reduction of sialometric values in AITD patients when compared to controls. A strong clinical suspicion of thyroid diseases should be considered when there is chronic hyposalivation; hence thyroid profile must also be done, if the known causes have been excluded.

To evaluate the work life and job satisfaction of pediatric generalists and subspecialists in comparison to each other and to a group of general internists and internal medicine subspecialists. Data were collected by survey of a national sample of 5704 general pediatricians, subspecialty pediatricians, general internists, internal medicine subspecialists, and family physicians who were selected randomly from the American Medical Association Masterfile using stratified sampling with disproportionate weighting to ensure ethnic diversity and representation of high managed care areas. Surveys were mailed up to 4 times and contained 150 items that reflected 10 facets of physician job satisfaction as well as an assessment of individual and practice demographic information. This study reports data from all groups except for family medicine. The adjusted response rate was 58% for general pediatricians (n = 590), 67% for specialty pediatricians (n = 345), and 52% (n = 1823) for the entire pool. In comparison with general internists, general pediatricians were more likely to be female (44% vs 24%); to work part time (20% vs 12%); to have lower annual income ($125 679 vs $143 875); and to report significantly higher levels of job, career, and specialty satisfaction on a 5-point scale (3.81 vs 3.52, 3.80 vs 3.55, and 3.76 vs 3.17 respectively). In comparison with internal medicine subspecialists, pediatric subspecialists were more likely to be female (42% vs 22%); to work in academically affiliated settings (35% vs 17%); to have lower incomes ($156 284 vs $192 006); to receive significantly less time for a complete history and physical examination (39 minutes vs 51 minutes); and to report similar levels of job, career, and specialty satisfaction (3.69 vs 3.71, 3.74 vs 3.78, and 3.60 vs 3.47 respectively). Of all 4 physician groups, general pediatricians worked the fewest hours (50/week), spent the greatest percentage of time in the office and the lowest percentage in the hospital (58% and 16%, respectively), saw the lowest percentage of patients with complex medical and complex psychosocial problems (15% and 17%, respectively), and were the least likely to endorse symptoms of burnout or job stress (13% and 18%, respectively). In comparison, pediatric subspecialists worked longer hours (59/week), spent the lowest percentage of time in the office and the greatest percentage of time in the hospital (22% and 44%, respectively), saw a much higher percentage of patients with complex medical and complex psychosocial problems (46% and 25%, respectively), and reported significantly higher levels of burnout and job stress (23% and 26%, respectively). Despite lower incomes, general pediatricians reported the highest levels of satisfaction and the least job stress of all 4 physician groups, whereas pediatric subspecialists reported levels of stress and burnout that raise significant concerns for the workforce of pediatric subspecialists of the future. Initiatives that improve clinical workload, balance inpatient and outpatient hours, and increase personal time of pediatric subspecialists should be considered.

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.

Variations between countries in leisure-time physical activity (LTPA) can be used to test the convergence thesis, which expects that ethnic minority groups change towards the LTPA levels of the native population of host countries. The aim of this study was to test whether similar differences in LTPA between the native populations of England and the Netherlands are also observed among the Indian and African descent groups living in these countries. We used English and Dutch population-based health surveys that included participants aged 35-60 years of European (n(english) = 14,723, n(dutch) = 567), Indian (n(english) = 1264, n(dutch) = 370) and African-Caribbean (n(english) = 1112, n(dutch) = 689) descent. Levels of LTPA (30-minute walking, any reported cycling, gardening, dancing and playing sports) were estimated with age-sex-standardized prevalence rates. Comparisons among groups were made using adjusted Prevalence Ratios (PRs). Within both countries and compared with the European group, Indian and African groups had lower levels of gardening and cycling, whereas the African groups had higher levels of dancing. Between countries, among the European groups, the Netherlands showed higher prevalence of cycling than England, PR = 2.26 (95% CI: 2.06-2.48), and this was 2.85 (1.94-4.19) among Indian descent, and 2.77 (2.05-3.73) among African descent. For playing sports, this was PR = 1.30 (1.23-1.38), 1.43 (1.24-1.66) and 1.22 (1.10-1.34), whereas for gardening this was PR = 0.71 (0.65-0.78), 0.65 (0.52-0.81) and 0.75 (0.62-0.90), respectively. Walking and dancing showed inconsistent differences between the countries and ethnic groups. This cross-national comparison supports the expectation that LTPA of Indian and African descent groups converge towards the national levels of England and the Netherlands respectively.

Low birth parameters are associated with an increased risk of insulin resistance, type 2 diabetes, glucose intolerance and hypertension at later life. Regular physical activity can counteract these metabolic disorders. We determined the relation of the declared physical activity and body composition in young adults with respect to their birth weight. A total of 156 subjects (52% women and 48% men) took part in the study (the average age 20.6±1.2 years). Participants who declared regular physical activity (minimum 3 times per week) were included in group I (n=66), others in group II (n=99). In each group, the percentage of people with small (SBW) and normal (NBW) birth weight was assessed. Information about birth parameters and duration of pregnancy was obtained from medical records. Infant's mass ≤2999 g was recognized as small birth weight. Body height, body weight, waist and hips circumferences and body composition by BIA were measured. Frequency of physical activity was determined during an interview. Percentage of participants with small birth weight was respectively 17% in group I and 21% in group II. In group I standardized body height was significantly lower in subjects with SBW in comparison with those with NBW. Participants from group II with SBW had markedly lower standardized body weight and standardized BMI than adults with NBW. Independently of birth weight physically active persons characterized higher WHR values than their non active counterparts. Body fat content was significantly lower in group I (both in participants with SBW and NBW). Women and men from group I with SBW had also higher fat free mass in comparison with those from group II. Body fat content in young adults with small birth weight is related to their physical activity. People who regularly exercise had lower fat mass in comparison with non exercising ones. This is the confirmation of a protective influence of physical activity.

To evaluate and compare the effect of antibacterial intracanal medicaments on inter-appointment flare-up in diabetic patients. Fifty diabetic patients requiring root canal treatment were assigned into groups I, II, and III. In group I, no intracanal medicament was placed. In groups II and III, calcium hydroxide and triple antibiotic pastes were placed as intracanal medicaments, respectively. Patients were instructed to record their pain on days 1, 2, 3, 7, and 14. Inter-appointment flare-up was evaluated using verbal rating scale (VRS). Overall incidence of inter-appointment flare-up among diabetic patients was found to be 16%. In group I, 50% of the patients and in group II, 15% of the patients developed inter-appointment flare-up. However, no patients in group III developed inter-appointment flare-up. The comparison of these results was found to be statistically significant (P = 0.002; χ(2) = 12.426). However, with respect to intergroup comparison, only the difference between groups I and III was found to be statistically significant (P = 0.002; χ(2) = 12.00). Calcium hydroxide and triple antibiotic paste are effective for managing inter-appointment flare-ups in diabetic patients. Triple antibiotic paste is more effective than calcium hydroxide in preventing the occurrence of flare-up in diabetic patients.

Objective: To determine whether semen and plasma presepsin values measured in men with normozoospermia and oligoasthenospermia undergoing invitro-fertilization would be helpful in predicting ongoing pregnancy and live birth. Methods: Group-I was defined as patients who had pregnancy after treatment and Group-II comprised those with no pregnancy. Semen and blood presepsin values were subsequently compared between the groups. Parametric comparisons were performed using Student’s t-test, and non-parametric comparisons were conducted using the Mann-Whitney U test. Results: There were 42 patients in Group-I and 72 in Group-II. In the context of successful pregnancy and live birth, semen presepsin values were statistically significantly higher in Group-I than in Group-II (p= 0.004 and p= 0.037, respectively). The most appropriate semen presepsin cut-off value for predicting both ongoing pregnancy and live birth was calculated as 199 pg/mL. Accordingly, their sensitivity was 64.5% to 59.3%, their specificity was 57.0% to 54.2%, and their positive predictive value was 37.0% to 29.6%, respectively; their negative predictive value was 80.4% in both instances. Conclusion: Semen presepsin values could be a new marker that may enable the prediction of successful pregnancy and/or live birth. Its negative predictive values are especially high. PMID:27882005

BACKGROUND: The formation of primary care groups (PCGs) and trusts (PCTs) has shifted the emphasis from individual practice initiatives to group-based efforts to control rising prescribing costs. However, there is a paucity of literature describing such group initiatives. We report the results of a multilevel group initiative, involving input from a pharmaceutical adviser, practice comparison feedback, and peer review meetings. AIM: To determine the impact of a prescribing initiative on the prescribing patterns of a group of general practices. DESIGN OF STUDY: A comparative study with non-matched controls. SETTING: Nine semi-rural/rural practices forming a commissioning group pilot, later a PCG, in Southern Derbyshire with nine practices as controls. METHOD: Practice data were collated for overall prescribing and for therapeutic categories, between the years 1997/1998 and 1998/1999 and analysed statistically. Prescribing expenditure trends were also collated. RESULTS: Although both groups came well within their prescribing budgets, in the study group this was for the first time in five years. Their rate of increase in expenditure slowed significantly following the initiative compared with that of the comparison group, which continued to rise (median practice net ingredient cost/patient unit (nic/PU) increase: Pound Sterling0.69 and Pound Sterling3.80 respectively; P = 0.03). The study group's nic/PU dropped below, and stayed below, that of the comparison group one month after the start of the initiative. For most therapeutic categories the study group had lower increases in costs and higher increases in percentage of generic items than the comparison group. Quality markers were unaffected. CONCLUSION: We suggest that practices with diverse prescribing patterns can work together effectively within a PCT locality to control prescribing costs. PMID:12030659

Haploidentical related donor (HRD) allogeneic hematopoietic stem cell transplantation (allo-HSCT) was developed as a valid option for the treatment of acute myeloid leukemia (AML) in the absence of a matched donor. However, many investigators are reluctant to consider the use of this alternative in elderly patients, anticipating high morbidity. Here, we report a single-center comparison of HRD versus matched sibling donor (MSD) and unrelated donor (UD) allo-HSCT for patients with AML aged ≥60 years. Ninety-four patients (MSD: n = 31; UD: n = 30; HRD: n = 33) were analyzed. The median age was 65 (range, 60 to 73) years. We observed a higher cumulative incidence of grade 3 to 4 acute graft-versus-host disease (GVHD) after UD allo-HSCT (MSD versus UD versus HRD: 3% versus 33% versus 6%, respectively; P = .006). Two-year cumulative incidence of moderate or severe chronic GVHD was 17%, 27%, and 16% in the MSD, UD, and HRD groups, respectively (P = .487). No difference was observed in the 2-year cumulative incidence of relapse or nonrelapse mortality (NRM) (relapse: MSD versus UD versus HRD: 32% versus 25% versus 25%, respectively; P = .411; NRM: MSD versus UD versus HRD: 19% versus 27% versus 24%, respectively; P = .709). At 2 years, progression-free survival, overall survival, and GVHD- and relapse-free survival were 48%, 50%, and 39%, respectively, in the MSD group; 48%, 51%, and 23%, respectively, in the UD group; and 50%, 52%, and 32%, respectively, in the HRD group, without statistically significant differences between the groups. We conclude that HRD allo-HSCT is highly feasible and no less efficient than MSD or UD allo-HSCT in patients with AML aged ≥60 years. Thus, the absence of a HLA-identical donor should not limit the consideration of allo-HSCT for the treatment of AML. Copyright © 2018 The American Society for Blood and Marrow Transplantation.

RANK/OPG/RANKL pathway plays a significant role in osteoclastogenesis, osteoclast activation, and regulation of bone resorption. The aim of this study was to investigate the association of RANKL gene polymorphisms (rs9533156 and rs2277438) with chronic periodontitis and peri-implantitis in an Iranian population. 77 patients with chronic periodontitis, 40 patients with peri-implantitis and 89 periodontally healthy patients were enrolled in this study. 5cc of blood was obtained from the cephalic vein of subjects arms and transferred into tubes containing EDTA. Genomic DNA was extracted using Miller's Salting Out technique. The DNA was transferred into 96 division plates, transported to Kbioscience Institute in United Kingdom and analyzed using the Kbioscience Competitive Allele Specific PCR (KASP) technique. Differences in the frequencies of genotypes and alleles in the disease and control groups were analyzed using Chi-square and Fisher's exact statistical tests. Comparison of frequency of alleles in SNP rs9533156 of RANKL gene between the chronic periodontitis group with the control and peri-implantitis groups revealed statistically significant differences (P=0.024 and P=0.027, respectively). Comparison of genotype expression of SNP rs9533156 on RANKL gene between the peri-implantitis group with chronic periodontitis and control groups revealed statistically significant differences (P=0.001); the prevalence of CT genotype was significantly higher amongst the chronic periodontitis group. Regarding SNP rs2277438 of RANKL gene, comparison of prevalence of genotypes and frequency of alleles did not reveal any significant differences (P=0.641/P=0.537, respectively). The results of this study indicate that CT genotype of rs9533156 RANKL gene polymorphism was significantly associated with peri-implantitis, and may be considered as a genetic determinant for peri-implantitis.

To compare the short-term efficacy of anterior cervical discectomy and fusion(ACDF) with traditional nail plate system and Zero-profile device in the treatment of cervical spondylotic myelopathy(CSM). The clinical data of 45 patients with CSM treated from July 2014 to August 2015 was retrospectively analyzed. There were 23 males and 22 females with an average age of 53.7 years old(range, 32 to 71 years old). The course of disease was 5 months to 2 years. All the patients were treated with ACDF with 24 cases by traditional nail plate system fixation(group A) and 21 cases by Zero-P system fixation(group B). Operation time and intraoperative bleeding were compared between two groups. Neurological function and cervical pain were evaluated by Japanese Orthopaedic Association scores (JOA) and visual analogue scale (VAS), respectively. Cervical curvature(Cobb angle) change and intervertebral fusion were evaluated by X-rays and CT. And associated complications were analyzed in two groups. All the patients were followed up for 12 to 16 months with an average of 14 months. Operation time of group A and B was(87.6±23.2) min and (62.7±17.3) min respectively, and the difference was significant between two groups; and intraoperative bleeding was (80.2±36.8) ml and (78.4±29.6) ml respectively, and the difference was not significant. At final follow-up, JOA and VAS of all patients were obvious improved, but there was no significant difference between two groups. Preoperative Cobb angle in group A and B was (8.7±4.3) ° and (8.6±4.2) ° respectively, and the difference was significant. The Cobb angle at final follow-up was (14.5±6.4) ° and (17.4±8.6) ° respectively, and the difference between two groups was significant. The incidence of dysphagia in group A and B were 29.17% and 9.52% respectively, and there was significant difference between two groups. All intervertebral spaces got fusion at final follow-up. No tracheo-asophageal injury and recurrent laryngeal nerve damage or other complications were found. No fusional migration, subsidence, loosening, breakage, etc. were found. The clinical comparison of Zero-P interbody fixation system and cervical plate internal fixation for the treatment of cervical spondylosis was quite fair, but Zero-P showed a better therapeutic effect with improvement of life quality.

Since awake craniotomy (AC) has become a standard of care for supratentorial tumour resection, especially in the motor and language cortex, determining the most appropriate anaesthetic protocol is very important. The aim of this retrospective study is to compare the effectiveness of conscious sedation (CS) to "awake-asleep-awake" (AAA) techniques for supratentorial tumour resection. Forty-two patients undergoing CS and 22 patients undergoing AAA were included in the study. The primary endpoint was to compare the CS and AAA techniques with respect to intraoperative pain and agitation in patients undergoing supratentorial tumour resection. The secondary endpoint was comparison of the other intraoperative complications. This study results show that the incidence of intraoperative agitation and seizure were lower in the AAA group than in the CS group. Intraoperative blood pressures were significantly higher in the CS group than in the AAA group during the pinning and incision, but the level of blood pressures did not need antihypertensive treatment. Otherwise, blood pressures were significantly higher in the AAA group than in the CS group during the neurological examination and the severity of hypertension needed statistically significant more antihypertensive treatment in the AAA group. As a result of hypertension, the amount of intraoperative bleeding was higher in the AAA group than in the CS group. In conclusion, the AAA technique may provide better results with respect to agitation and seizure, but intraoperative hypertension needed a vigilant follow-up especially in the wake-up period.

This study aimed to compare the real-world effectiveness of valsartan and non renin-angiotensin system (non-RAS) agent monotherapy on the incidence of new on-set diabetes (NOD) in Chinese hypertensive patients. It was based on an electronic Health Recording System database from Minhang District of Shanghai. Hypertensive patients aged ≥18 years continuously taking either valsartan or non-RAS agent monotherapy for >12 months were included. Hazard ratios (HR) of NOD events were estimated using propensity score matching method and multivariate regression. Of 29295 patients, there were 2107 in valsartan group, 21397 in CCB group, 4094 in β-blockers group and 1697 in diuretics group. Two-year follow-up revealed NOD rates of 11.09 and 14.22 per 100 persons per year in valsartan and non-RAS inhibitor groups (HR = 0.77, 95% confidence interval 0.65-0.93, P = 0.006), respectively. Among non-RAS agents, CCB group had the highest incidence of NOD (21.72 per 100 persons per year). Comparisons between CCB sub-groups revealed the highest NOD incidence for nifedipine, followed by amlodipine and felodipine. NOD incidences in β-blockers and diuretics groups (11.70 and 10.50 per 100 persons per year, respectively) were not significantly different from valsartan group. Compared with non-RAS inhibitors, particularly CCBs, valsartan could significantly reduce the incidence of NOD.

To compare outcomes of accelerated and conventional corneal cross-linking (CXL) for progressive keratoconus (KC). Patients were divided into two groups as the accelerated CXL group and the conventional CXL group. The uncorrected distant visual acuity (UDVA), corrected distant visual acuity (CDVA), refraction and keratometric values were measured preoperatively and postoperatively. The data of the two groups were compared statistically. The mean UDVA and CDVA were better at the six month postoperative when compared with preoperative values in two groups. While change in UDVA and CDVA was statistically significant in the accelerated CXL group (p = 0.035 and p = 0.047, respectively), it did not reach statistical significance in the conventional CXL group (p = 0.184 and p = 0.113, respectively). The decrease in the mean corneal power (Km) and maximum keratometric value (Kmax) were statistically significant in both groups (p = 0.012 and 0.046, respectively in the accelerated CXL group, p = 0.012 and 0.041, respectively, in the conventional CXL group). There was no statistically significant difference in visual and refractive results between the two groups (p > 0.05). Refractive and visual results of the accelerated CXL method and the conventional CXL method for the treatment of KC in short time period were similar. The accelerated CXL method faster and provide high throughput of the patients.

In our practice, the authors found that molding helmet used for plagiocephaly preoperatively, in patients with sagittal synostosis, decreased bathrocephaly, forehead bossing, and improved posterior vertex, as well as Cephalic Index (CI). This prompted us to investigate the impact of preoperative molding helmet in patients with sagittal synostosis. A prospective study was performed on patients undergoing surgical correction of sagittal synostosis, over a 5-year period. Patients were categorized into 2 groups. "No Helmet group" only had surgical correction, and "Helmet group" had preoperative molding helmet, prior to surgical correction. Cephalic Index for the 2 groups was compared using t-test. There were 40 patients in the No Helmet group and 18 patients in the Helmet group. For No Helmet group, mean CI at presentation, immediately preoperative, and postoperatively was 0.70 (±0.045), 0.70 (±0.020), and 0.80 (±0.030), respectively, and for Helmet group, it was 0.69 (±0.023), 0.73 (±0.036), and 0.83 (±0.036), respectively. There was no statistically significant difference between CI of the 2 groups at presentation (P = 0.45). Comparison of postoperative CI did show a statistically significant difference between the groups (P = 0.01). For Helmet group, on comparison of CI at presentation and preoperative CI (after helmet therapy), a statistically significant improvement in CI was observed (P = 0.0004). Our results suggest that preoperative molding helmet can decrease bathrocephaly, forehead bossing, and improve posterior vertex as well as CI, prior to surgery and thus can be used as a valuable adjunct in patients with sagittal synostosis.

The influence of magnetic field with the intensity of 0.07T on the hatching of the Hampshire breed chicken was investigated. The hatchability of the eggs that were influenced by magnetic field during the storage of the egg set (20-40 min) was increased in comparison with eggs that were not influenced by magnetic field (p < 0.05). In the eggs influenced by magnetic field during their incubation, the hatchability in experimental groups E1 and E2 decreased to 70.08 +/- 1.93% and 70.75 +/- 2.13%, respectively. The difference were significant (p < 0.001) in comparison with the control groups C1 and C2. The negative influence of magnetic field was manifested by lower weight of the hatched chickens in the experimental groups E1 (35.07 +/- 0.95 g) and E2 (35.94 +/- 0.97 g). The results were relevant (p < 0.05) in comparison with the control groups with the average weight of hatched chickens 41.83 +/- 1.15 g (C1) and 44.27 +/- 0.73 g (C2).

To evaluate the impact of the University of Kentucky's Healthy Choices for Every Body (HCEB) adult nutrition education curriculum on participants' food resource management (FRM) skills and food safety practices. A quasi-experimental design was employed using propensity score matching to pair 8 intervention counties with 8 comparison counties. Independent-samples t tests and ANCOVA models compared gains in FRM skills and food safety practices between the intervention and comparison groups (n = 413 and 113, respectively). Propensity score matching analysis showed a statistical balance and similarities between the comparison and intervention groups. Food resource management and food safety gain scores were statistically significantly higher for the intervention group (P < .001), with large effect sizes (d = 0.9) for both variables. The group differences persisted even after controlling for race and age in the ANCOVA models. The HCEB curriculum was effective in improving the FRM skills and food safety practices of participants.

This study evaluated the cleaning efficacy of a root canal system by Nd:YAG laser and rotary instruments. Sixty single-rooted human teeth were divided into four experimental groups (n=15). In the first group the teeth were prepared with a step-back technique using conventional K-files. In the second and third groups, tooth preparation was carried out using Nd:YAG laser and rotary NiTi instruments, respectively. Teeth in the fourth group were prepared by combined laser and rotary methods. The smear layer remaining on canal walls was then assessed by scanning electron microscopy in the coronal, middle, and apical portions. The comparison of smear layer removal efficacy between groups was carried out by Kruskal-Wallis and Mann-Whitney U tests. The mean grades of smear layer removal in rotary-laser, rotary, laser and step-back techniques were 1.34 ± 0.18, 2.2 ± 0.28, 1.91 ± 0.25, and 2.42 ± 0.19, respectively. On the whole, differences between rotary-laser and rotary groups, step-back, and the three other techniques (rotary, laser, and rotary-laser) were significant at p=0.034. Based on the findings of this study, the cleaning efficacy of rotary, laser, and rotary-laser techniques were better than the step-back technique and the combined laser and rotary technique was the most efficient method.

Communication skills training, responsibility, respect, and self-awareness are important indexes of changing learning behaviours in modern approaches. The aim of this study was to investigate the efficacy of three learning approaches, collaborative, context-based learning (CBL), and traditional, on learning, attitude, and behaviour of undergraduate nursing students. This study was a clinical trial with pretest and post-test of control group. The participants were senior nursing students. The samples were randomly assigned to three groups; CBL, collaborative, and traditional. To gather data a standard questionnaire of students' behaviour and attitude was administered prior to and after the intervention. Also, the rate of learning was investigated by a researcher-developed questionnaire prior to and after the intervention in the three groups. In CBL and collaborative training groups, the mean score of behaviour and attitude increased after the intervention. But no significant association was obtained between the mean scores of behaviour and attitude prior to and after the intervention in the traditional group. However, the mean learning score increased significantly in the CBL, collaborative, and traditional groups after the study in comparison to before the study. Both CBL and collaborative approaches were useful in terms of increased respect, self-awareness, self-evaluation, communication skills and responsibility as well as increased motivation and learning score in comparison to traditional method.

The aim of this study is to evaluate the hepatoprotective effect of rutin (RTN) in comparison to silymarin (SLM) against acetaminophen (APAP)-induced hepatotoxicity in rats. Male Wistar albino rats (n=24) of 3 months age were equally divided into four groups. Group 1 served as normal control. Hepatotoxicity was induced in the remaining three groups with administration of 500 mg/kg po APAP from day 1-3. Groups 2, 3, and 4 were subsequently administered orally with distilled water, 25 mg/kg of SLM, and 20 mg/kg of RTN, respectively, for 11 days. The mean body weights and biomarkers of hepatotoxicity were estimated on day 0, 4 (confirmation of toxicity), and 15 (at the end of treatment). Hematological parameters were evaluated on day 4 and 15. Antioxidant profile and adenosine triphosphatases (ATPases) were assessed at the end of the experiment. Liver tissues were subjected to histopathology and transmission electron microscopy after the sacrifice on day 15. Antioxidant profile, ATPases, and hematological and sero-biochemical parameters were significantly altered, and histopathological changes were noticed in the liver of toxic control group. These changes were reversed in groups 3 and 4 that were administered with SLM and RTN, respectively. The results of the present investigation enunciated that SLM has potent hepatoprotective activity though the RTN was found superior in restoring the pathological alterations in paracetamol-induced hepatotoxicity in Wistar albino rats.

Myasthenia gravis (MG) is an autoimmune disease commonly treated with immunosuppressants. We evaluated the novel immunosuppressant, rapamycin (RAPA), in a rat model of experimental autoimmune MG (EAMG). Mortality rates in the RAPA (12%) were significantly down compared with the EAMG (88%) or cyclophosphamide (CTX) (68%) intervention groups. Muscular weakness decreased after both RAPA and CTX treatment. However, Lennon scores were lower (1.74 ± 0.49, 3.39 ± 0.21, and 3.81 ± 0.22 in RAPA, CTX, and EAMG groups, respectively), and body weights (203.12 ± 4.13 g, 179.23 ± 2.13 g, and 180.13 ± 5.13 g in RAPA, CTX, and EAMG groups, respectively) were significantly higher, only in the RAPA group. The proportion of regulatory T cells (Treg) significantly increased, while that of Th17 cells significantly decreased in the RAPA group compared with the EAMG group. In comparison, CTX intervention resulted in increased Th17 but significantly decreased Tregs. Hence, RAPA can be more effectively used in comparison with CTX to treat MG, with an efficacy higher than that of CTX. In addition, our results suggest RAPA's efficacy in alleviating symptoms of MG stems from its ability to correct the Treg/Th17 imbalance observed in MG. © 2017 The Author(s).

Various chemotherapy protocols for treating lymphoma in dogs have been published; however, comparison of protocols from different studies is difficult, especially when evaluating survival time and toxicoses. The choice of COAP (C, cyclophosphamide; O, vincristine; A, cytosine arabinoside; P, prednisone) and a modified University of Wisconsin 19-week (UW-19) induction protocol has no influence on overall survival times in dogs with lymphoma. One hundred and one dogs with multicentric lymphoma. Retrospective study (2001-2006). Dogs induced with either an 8-week COP-based protocol (C, cyclophosphamide; O, vincristine; and P, prednisone) with maintenance therapy (COAP group) or a 19-week CHOP (C, cyclophosphamide; H, doxorubicin; O, vincristine; and P, prednisone) based protocol (UW-19 group) were compared in terms of the duration of first remission, survival time, toxicoses, and cost. There were 71 dogs in the COAP group and 30 dogs in the UW-19 group. Various protocols were used after the first relapse. The median duration of the first remission for the COAP and UW-19 groups were 94 days (range, 6-356 days) and 174 days (28-438 days), respectively (P < .01). The median survival times for dogs in the COAP and UW-19 groups were 309 days (6-620 days) and 275 days (70-1102+ days), respectively (P = .09). Dogs in the COAP group had a hazard ratio of 1.9 (95% CI 1.1-3.4) for death relative to the UW-19 group (P = .03), after controlling for the confounders (World Health Organization clinical stage, age, sex, use of doxorubicin during reinduction). The severity of neutropenia and gastrointestinal toxicoses were significantly higher in the UW-19 group than in the COAP group (P = .01 and P < .01, respectively). Use of a long-term doxorubicin-containing sequential combination chemotherapy protocol is associated with a decreased risk of relapse and death relative to a non-doxorubicin-containing protocol.

The optimal management method of upper ureteral stones >2 cm is still a challenge. We performed a prospective randomized comparison between laparoscopic ureterolithotomy (LU) and ureteroscopic lithotripsy for upper ureteral calculus >2 cm to evaluate safety and efficacy of both procedures. Between January 2010 and May 2012, 110 patients with a single radiopaque upper ureteral calculus >2 cm were included in the present study. Randomization was done in two groups-group A: LU was performed and group B: Ureteroscopy (URS) was performed using a 6/7.5F semirigid ureteroscope (Richard Wolf) with holmium laser intracorporeal lithotripsy. Statistical analysis was performed regarding demographic profile, success, retreatment, auxiliary procedure rates, and also complications. Out of the total 110 patients, 54 patients were enrolled in group A and 56 patients were enrolled in group B. Mean stone size was 2.3±0.2 cm in group A versus 2.2±0.1 cm in group B (p=0.52). The overall 3-month stone-free rate was (50/50) 100% for group A versus (38/50) 76% for group B (p=0.02). The retreatment rate was significantly greater in group B than group A (8% vs. 0%, respectively; (p=0.01). Auxiliary procedure rate was higher in group B than in group A (26% vs. 0% respectively; p=0.001). The complication rate was 12% in group A versus 26% in group B (p=0.001). For upper ureteral stones of size greater than 2 cm, LU has a greater stone clearance rate, comparable operating time, lesser need for auxiliary procedure, and complication rate as compared to URS.

To compare two methods of hemorrhoid treatment. This prospective study included 240 patients with hemorrhoids stage III-IVA. Stages III and IVA were diagnosed in 156 (65%) and 84 (35%) patients respectively. Randomization was performed using envelopes method in one to one distribution. In group 1 (n=120) Doppler-assisted dearterialization of internal hemorrhoids with mucopexy was performed (DDM), in group 2 (n=120) - hemorrhoidectomy using harmonic scalpel (HE). Duration of surgery was 17.9±6.1 and 34.5±10.1 minutes in DDM and HE groups respectively (p<0.01). Postoperative pain severity was higher in group 2 (4.8 compared with 2.5 scores of the first group (p<0.01). Narcotic analgesics were used less often in DDM group (1.3 doses compared with 6.1 doses in HE group (p<0.01). Disability period was 14.4±5.2 and 30.3±5.4 days in both groups respectively (p<0.01). Immediate postoperative complications occurred in 9 (7.5%) and 19 (15.8%) patients of DDM and HE groups respectively. Recurrent prolapse of internal hemorrhoids was diagnosed in 2 (1.7%) patients of the 1st group in terms of up to 45 days. DDM is reliable minimally invasive method of hemorrhoids stage III-IVA treatment and has similar efficacy with HE. DDM reduces postoperative pain severity, hospital stay and disability period.

The aim of this study was to determine the similarities and differences in social network characteristics, satisfaction and wishes with respect to the social network between people with mild or borderline intellectual disabilities (ID), people with autism spectrum disorders (ASD) and a reference group. Data were gathered from 105 young adults living independently in the community. The social networks of people with ID and ASD are more restricted than those of the reference group. Compared with the other groups, people with ASD are less often satisfied with their networks. Each group has its own characteristics, issues and wishes with respect to their social network. Practical measures to enable professionals to adapt to these issues are discussed.

Little is known about whether the arteriovenous type haemodialysis access affects cardiac function and whether it is still advantageous to the uremic patient with symptomatic heart disease. We conducted a retrospective comparative study. Patients with heart disease and end-stage renal disease that had a new chronic access created between January 2007 and December 2008 and met the inclusion criteria were assessed. The endpoint was major adverse event (MAE)-free survivals of arteriovenous access (AVA) and tunneled cuffed double-lumen central venous catheter (CVC) groups. Whether accesses worsened heart failure was also evaluated. There were 43 CVC patients and 60 AVA patients. The median follow-up time from access creation was 27.6 months (IQR 34.7, 10.9~45.6). Although CVC patients were older than AVA patients (median age 78.0, IQR 14.0 vs. 67.5, IQR 16.0, respectively, p = .009), they manifested non-inferior MAE-free survival (mean 17.1, 95% CI 10.3~24.0 vs. 12.9, 95% CI 8.5~17.4 months in CVC and AVA patients, respectively, p = .290). During follow-up, more patients in the AVA group than in the CVC group deteriorated in heart failure status (35 of 57 vs. 10 of 42, respectively, odds ratio 5.1, p < .001). Preoperative-postoperative pairwise comparison of echocardiographic scans revealed an increased number of abnormal findings in the AVA group (Z = 3.91, p < .001), but not in the CVC group. In patients with both symptomatic heart disease and end stage renal disease (ESRD), CVC patients showed non-inferior MAE-free survival in comparison to those in the AVA group. AV type access could deteriorate heart failure. Accordingly, uremic patients with symptomatic heart disease are not ideal candidates for AV type access creation.

To reveal the specific features of gastroesophageal reflux disease (GERD) associated with obesity and overweight, by investigating the clinical and endoscopic manifestations of the disease, 24-hour pH-metry scores, and leptin levels. A total of 131 patients with GERD were examined. The data about complaints and those from life and medical histories were collected; anthropometric measurements and the results of blood biochemical tests, esophagoduodenoscopy (EPDS), and pH-metry were assessed; and the serum levels of leptin and its receptor were estimated. The patients were allocated into a study group (104 obese and/or overweight patients) and a comparison one (27 normal weight people). Waist circumference, hip circumference, and blood glucose levels proved to be statistically significantly higher in the study group (p<0.00000, p<0.00002, and p<0.02, respectively). The obese patients were found to have a statistically significantly higher level of leptin and a lower level of its soluble receptors: the median leptin levels were 30.42 (13.42-45.62) ng/ml in the study group and 5.47 (3.35-7.68) ng/ml in the comparison group; the median levels of the receptors were 18.83 (14.98-25.11) ng/ml and 30.93 (24.68-33.53) ng/ml, respectively). This group showed a moderate negative correlation between these indicators (rs=-0.451; p<0.0004). The study group displayed higher pH values in the gastric cardia and body (p<0.05 and p<0.04, respectively). The mucosal contact time with the refluxate having with a low pH value (<4) in the above segments turned out to be longer in the comparison group (p<0.05). There were weight-independent relationships of the leptin level to its spread, aggressiveness quotient, to the highest pH value in the gastric cardia and body, and to the mucosal contact time with the refluxate having a pH below 4.0 (rs=0.543; p<0.006; rs=0.432; p<0.04; rs=0.431; p<0.04; rs=-0.450; p<0.03, respectively), leptin receptors with a pH ratio in the gastric cardia and body, to the number of reflux episodes longer than 5 minutes in the esophagus, and to the De Meester index for this indicator (rs=0.471; p<0.04; rs=-0.455; p<0.04; rs=-0,454; p<0.04, respectively). Obese and overweight patients develop GERD in the presence of leptin resistance and biliary tract disease, which determines the specific features of the disease (alkaline or mixed refluxate) and the need for individualized therapy.

to assess the growth and pubertal development among a group of patients with β-Thalassemia Major (β-TM) and to evaluate the role of the pituitary gland and liver MRI signal intensity (SI) reduction in assessing and predicting the clinical severity of growth and pubertal dysfunctions. Thirty-eight patients with β-TM were examined and divided into two groups: Group I patients were of normal height and puberty and Group II patients had short statures and hypogonadism. Laboratory investigations included serum ferritin, LH, FSH, prolactin, TSH, and basal and dynamic growth hormones. Pituitary and liver MRIs were performed to assess the pituitary to fat (P/F) and liver to muscle (L/M) signal intensities (SI), respectively. Fifteen healthy and sex- and age-matched subjects were included as controls. Both patient groups had significantly elevated serum ferritin and significantly decreased prolactin and IGF1 compared to control subjects. Group II showed a significant reduction in LH, FSH, and IGF1 and a significant increase in ferritin in comparison with Group I and the control group, and it had a highly significant reduction in both P/F and L/M SI in comparison with Group I (p<0.001 and 0.008, respectively). The reduced P/F ratio was significantly correlated with FSH and LH, and a cutoff for a P/F ratio ≥0.94 was obtained to differentiate between Group I and II. MRI in conjunction with the P/F signal intensity ratio is a useful and noninvasive tool for the early diagnosis of pituitary iron overload.

Vitamin D deficiency during pregnancy is associated with some adverse pregnancy outcomes but its relationship with fetal growth is unknown. We compared the 25-hydroxy vitamin D levels between mothers and their small for gestational age (SGA) newborns with mothers and their appropriate for gestational age (AGA) newborns. The study population included pregnant women that referred to Afzalipour Hospital in Kerman from 2012 to 2013. The case and control group consisted of 40 pregnant mothers with SGA and AGA newborns, respectively. The maternal and infants 25-hydroxy vitamin D levels were measured in the two groups. 25-hydroxy vitamin D deficiency (<20 ng/ml) was statistically higher in women with SGA newborns in comparison to women with AGA newborns (p=0.003).Vitamin D deficiency was higher among the SGA newborns in comparison to AGA newborns (25% vs. 17.5%), although this finding was not statistically meaningful (p=0.379). The relationship of vitamin D deficiency levels between mothers and infants in both the SGA group and the AGA group was significant. Our study reveals a high prevalence of vitamin D deficiency in women with SGA infants in comparison to women with AGA children. In addition, maternal vitamin D deficiency is associated with its deficiency in newborns.

Obstructive sleep apnea syndrome obstructive sleep apnea syndrome is associated with symptoms including habitual snoring, witness apnea and excessive daytime sleepiness. Also obstructive sleep apnea syndrome is related to some occupations which are needed attention for work accident. We aimed to determine the prevalence of snoring, witnessed apnea and excessive daytime sleepiness in coal workers and healthy adults in Zonguldak city center, and also evaluate the differences between these groups. This study consisted of 423 underground coal workers and 355 individuals living in centre of Zonguldak. Study and comparison group were chosen by nonstratified randomized sampling method. Data were collected by a questionnaire that included information regarding snoring, witnessed apnea and excessive daytime sleepiness. Mean age was 43.3 ± 6.05 years in miners and 44.3 ± 11.8 years in comparison group. In miners, snoring frequency was determined as 42.6%, witnessed apneas were 4.0%, and daytime sleepiness were 4.7%. In comparison group, these symptoms were 38.6%, 4.8% and 2.8% respectively. There were no statistical differences between coal workers and comparison group in these symptoms. Also snoring prevalence was higher in smoker miners. We found that major symptoms of obstructive sleep apnea syndrome in coal workers are similar to general population in Zonguldak. Further studies that constucted higher populations and with polysomnography are needed to evaluate these findings.

Introduction Saliva is a complex secretion that protects and lubricates the oral cavity. Various systemic diseases and their treatment alter the salivary gland function; one such disease is Autoimmune Thyroid Disease (AITD). AITD has been postulated to exert its hormonal influence on the salivary glands, leading to reduced salivary output. There’s a paucity of literature, verifying the stated conjunction in human subjects. Aim The aim was to investigate the salivary profile in AITD patients and its comparison with controls. Materials and Methods Descriptive cross-sectional comparative study was conducted using convenience sampling method for screening the presence of thyroid disorders. Two groups comprising of 30 patients in each group diagnosed with autoimmune hypothyroiditis (n=30) and hyperthyroiditis (n=30) respectively and thirty healthy volunteers who were age and sex matched were included as controls. Saliva was collected and evaluated for Unstimulated Salivary Flow Rate (USSFR), pH and buffer capacity. ANOVA and Tukey post-hoc test was performed to find the statistical significance and for pairwise comparison. Results Statistically significant difference was observed between autoimmune hypothyroiditis, autoimmune hyperthyroiditis and control group with respect to USSFR (p<0.007), pH (p<0.001) and buffer capacity (p<0.001). On pairwise comparisons statistically significant difference was observed between autoimmune hypothyroiditis and autoimmune hyperthyroiditis with respect to controls. Conclusion We conclude that significant involvement of salivary glands may occur in cases of AITD. Our study showed significant reduction of sialometric values in AITD patients when compared to controls. A strong clinical suspicion of thyroid diseases should be considered when there is chronic hyposalivation; hence thyroid profile must also be done, if the known causes have been excluded.

Water molecules in the brain diffuse preferentially along the fiber tracts within white matter, which form the anatomical connections across spatially distant brain regions. A diffusion tensor (DT) is a probabilistic ellipsoid composed of 3 orthogonal vectors, each having a direction and an associated scalar magnitude, that represent the probability of water molecules diffusing in each of those directions. The 3D morphologies of DTs can be compared across groups of subjects to reveal disruptions in structural organization and neuroanatomical connectivity of the brains of persons with various neuropsychiatric illnesses. Comparisons of tensor morphology across groups have typically been performed on scalar measures of diffusivity, such as Fractional Anisotropy (FA), rather than directly on the complex 3D morphologies of DTs. Scalar measures, however, are related in nonlinear ways to the eigenvalues and eigenvectors that create the 3D morphologies of DTs. We present a mathematical framework that permits the direct comparison across groups of mean eigenvalues and eigenvectors of individual DTs. We show that group-mean eigenvalues and eigenvectors are multivariate Gaussian distributed, and we use the Delta method to compute their approximate covariance matrices. Our results show that the theoretically computed Mean Tensor (MT) eigenvectors and eigenvalues match well with their respective true values. Furthermore, a comparison of synthetically generated groups of DTs highlights the limitations of using FA to detect group differences. Finally, analyses of in vivo DT data using our method reveal significant between-group differences in diffusivity along fiber tracts within white matter, whereas analyses based on FA values failed to detect some of these differences.

Over the past decade, interest in complementary therapies and alternative medicine has escalated among midwives and the general public in response to increased demand from expectant mothers for more choice, control, and continuity in labor. The aim of this study was to explore if an aromatherapy and massage intrapartum service (AMIS) reduced the need for analgesia during labor. This article reports results related to the effects of an AMIS on type of analgesia chosen by women in labor, and on rates of anesthesia--one aspect of the full study. The study was conducted in a general maternity unit in southwest England, UK. A quantitative research approach was taken, whereby contemporaneously completed service evaluation forms of 1079 women (601 nulliparous women and 478 multiparous women; AMIS group) were retrospectively analyzed in comparison with the birth records of an equal number of similar women (comparison group). Data analysis was achieved by entering data from the forms and comparison sample into an SPSS package and running statistical tests. In the AMIS group, overall analgesia usage was higher for transcutaneous electrical stimulation at 34%, compared with 15.9% (p<0.001 allowing for parity), and for nitrous oxide and oxygen at 87.6%, compared with 80.8% (p<0.001). Pethidine use did not differ after adjustment for parity at 30.1%, compared with 24.2% (p=0.27) in the AMIS and comparison groups, respectively. Rates were lower in the AMIS group for epidural anesthesia at 29.7%, compared with 33.8% (p=0.004 allowing for parity) in the comparison group; spinal anesthesia at 6%; compared with 12.1% (p<0.001) in the comparison group; and general anesthesia at 0.8%, compared with 2.3% (p=0.033) in the comparison group. Having an AMIS appears to have a positive impact on reducing rates of all types of intrapartum anesthesia. The Service is a beneficial addition to conventional midwifery practice that may influence mode of delivery and reduce general anesthesia rates.

In answering the call for empirical documentation of the effect of ropes and challenge course participation on the psychosocial function and sport performance of athletes and teams, exploratory studies have identified postcourse changes in group cohesion and approaches to sport competition. The purpose of the current study was to utilize a pretest-posttest comparison group design to expand knowledge in this area. 35 members of a girls' high school tennis team participated. The 16 individuals who participated in a preseason program and the 19 individuals who did not comprised the treatment and comparison groups, respectively. Team members completed the Group Environment Questionnaire and the Sport Orientation Questionnaire four days prior to and two days after the course experience. A series of 2 x 2 analyses of variance, (group x time) run on each of the scales, gave a significant group x time interaction on one social cohesion scale but none for scores on the Sport Orientation Questionnaire. The findings are discussed in relation to research and the implementation of these programs with athletes.

Maintenance of good oral hygiene is important for patients undergoing fixed orthodontic treatment. The aim of this study was to evaluate the effectiveness of a manual orthodontic toothbrush, powered toothbrush with oscillating head and sonic toothbrush in controlling plaque, gingivitis and interdental bleeding in patients undergoing fixed orthodontic treatment, and to compare their relative efficacy. Sixty subjects, who were to receive orthodontic treatment with both upper and lower fixed appliances, were randomly divided into three study groups, with 20 patients in each group. Groups I to III were given manual orthodontic, powered and sonic toothbrushes, respectively. Plaque index (PI), gingival index (GI) and interdental bleeding index were scored to assess the level of plaque accumulation, gingival health and interdental bleeding at baseline; 4 and 8 weeks recall visits after fixed appliance bonding. Paired t-tests and one-way analysis of variance (ANOVA) tests were used for intragroup and intergroup comparisons. The level of statistical significance was set at p < 0.05. This study showed that a significant reduction in all the three indices scores was found from baseline to 4 and 8 weeks in group III. On intergroup comparison, no statistically significant differences were detected between the three groups for any of the parameters assessed. On intragroup comparison, sonic brushes performed superiorly in reducing gingivitis, plaque and interdental bleeding as compared to the manual orthodontic and powered brushes. On intergroup comparison, the relative comparative effectiveness was found to be similar for all the three brushes. How to cite this article: Sharma R, Trehan M, Sharma S, Jharwal V, Rathore N.

To evaluate local recurrence (LR) in women with early breast cancer (BC) who underwent intraoperative radiation therapy with electrons particles (IORT-E) or adjuvant hypofractionated external radiotherapy (HYPOFX). We retrospectively analyzed 470 patients with early BC treated at our center from September 2009 to December 2012. 235 women were treated with breast-conserving surgery and immediate IORT-E (21 Gy/1 fraction) while 235 patients underwent wide excision followed by hypofractionated whole-breast irradiation. Radiotherapy modality was chosen according to an individualized decision based on tumor features, stage, technical feasibility, age, and acceptance to be enrolled in the IORT-E group. After a median follow-up of 6 years, we observed 8 (3.4%) and 1 (0.42%) LR in the IORT-E and in the HYPOFX group ( p  = 0.02), respectively. The two groups differed in the prevalence of clinical characteristics ( p  < 0.05): age, tumor size, surgical margins, receptors, ki67, and histology. 4 and 1 woman in the IORT-E and HYPOFX group died of BC, respectively ( p  = 0.167). OS and DFS hazard ratio [HR] were 2.14 (95% IC, 1.10-4.15) and 2.09 (95% IC, 1.17-3.73), respectively. Our comparison showed that IORT-E and HYPOFX are two effective radiotherapy modalities after conservative surgery in early BC. However, at 6 years a significant higher rate of LR occurred in patients submitted to IORT-E with respect to HYPOFX. This finding may be correlated to some subsets of patients who, depending on the biological characteristics of the BC, may be less suitable to IORT-E.

The presence of limits or distortions in the children's communicative behaviours (due to a chronic illness) may interfere with the possibility to build secure attachment relationships. Moreover, the distress that the atypical chronic illness condition brings to family life may interfere the intergenerational transmission of attachment. This study evaluated the associations between maternal attachment representations, emotional availability and mother-child attachment in a clinical and in a comparison group. Forty infants (23 female) in their 14th month of life and their mothers participated in this study, 20 dyads with clinical infants (10 premature infants and 10 infants affected by atopic dermatitis) and 20 full-term and healthy comparison infants. The Adult Attachment Interview, the Emotional Availability Scales (EAS) and the Strange Situation Procedure were used to assess, respectively, the security of mothers' attachment representations, the emotional availability and the quality of mother-child attachment. We found that the two groups (clinical vs. comparison) did not differ with respect to the Adult Attachment Interview and the Emotional Availability Scales measures. A significant difference was found in the distribution of the infant-mother attachment patterns, with a higher incidence of insecure infants in the clinical group. In the typically developing group, more secure maternal attachment representations predicted more emotional availability in mother-infant interactions, which predicted more secure infant-mother attachments. However, we did not find similar support for intergenerational transmission of attachment in the clinical group. We speculate that constant concerns about the child's health condition and communicative difficulties of clinical infants may hamper or even mitigate the intergenerational transmission of attachment. © 2011 Blackwell Publishing Ltd.

2018-01-01

PURPOSE: To evaluate the impact of a postdischarge ostomy support program as an adjunct to nurse-led ostomy care on preventable healthcare utilization. DESIGN: A cross-sectional study. SUBJECTS AND SETTING: A postdischarge support program offered by an ostomy product's manufacturer provides persons living with an ostomy with patient-centered and easily accessible assistance. Individuals who underwent ostomy surgery within 18 months prior to the survey date were selected from an ostomy patient database maintained by the ostomy patient support program provider. Of 7026 surveys sent to program enrollees, 493 (7%) responded, compared with 225 (5%) out of 4149 surveys sent to individuals in a comparison group. The 2 groups were similar in demographics. A majority of the survey respondents were female (60% of program enrollees vs 55% of respondents in the comparison group). Among the program enrollees, 44% had colostomy, 43% had ileostomy, 10% had urostomy, and 4% had at least 2 types of ostomy surgery compared with 52%, 32%, 12%, and 4% of the respondents in a comparison group, respectively. METHODS: The study compared hospital readmission and emergency room (ER) visit rates attributable to ostomy complications between program enrollees and respondents in the comparison group. The event rates were measured in 2 study periods: within the first month of discharge and after the first month of discharge. Eligible individuals received an online survey that included the following domains: characteristics of ostomy surgery; readmissions and ER visits within the first month or after the first month of discharge, including reasons for preventable events; and level of health care access. Multivariate logistic regressions controlling for covariates were applied to investigate associations between program enrollment and ostomy-related readmission or ER visit rates. RESULTS: Logistic regression analyses showed that, when compared with respondents in the comparison group, program enrollees had a significantly lower likelihood of being readmitted and visiting the ER due to ostomy complications after the first month of hospital discharge and up to 18 months postdischarge (odds ratio [OR] = 0.45; 95% confidence interval [CI], 0.27-0.73; and OR = 0.37; 95% CI, 0.22-0.64, respectively). CONCLUSIONS: Findings suggest that enrolling patients in the postdischarge ostomy support program provides an effective approach to reducing preventable healthcare utilization. PMID:29189646

The molecular structures of the group IB trimers, Cu3, Ag3, and Au3, have been determined by using the semi-empirical diatomics-in-molecules theory. The trimers are found to have C2v symmetry with bond angles between 65° and 80°. The trimers are bound with respect to dissociation to the asymptotic limit of an atom plus a diatom. The binding energies per atom for Cu3, Ag3, and Au3 are 1.08, 0.75, and 1.16 eV, respectively. The vibrational frequencies of the trimers have been determined for comparison with experimental results. The vibrational frequencies are characterized by low values for the bending and asymmetric stretch modes. The frequency of the symmetric stretch of the trimer is higher than the stretching frequency of the corresponding diatomic. A detailed comparison of the theoretical results with the previously measured Raman spectra of matrix isolated Ag3 is presented. PMID:16592885

Cognitive impairment occurs in 40%-65% of patients with multiple sclerosis (MS). Several techniques for cognitive rehabilitation (CR) in these patients have been evaluated; however, the results have been controversial. In this study, we investigated the efficacy of group compensatory CR in patients with MS-related cognitive impairment. Thirty-four female patients with diagnosed relapsing-remitting MS and evidence of impaired cognitive function were included and randomized to intervention (n = 17) and control (n = 17) groups. CR intervention consisted of eight 2-hour sessions of comprehensive group CR over a 4-week period that focused on improvement of memory, attention, and executive function. As placebo, the control group received the same number of non-therapeutic group sessions. Assessment of cognitive function was performed before intervention (pretest), at the end of intervention (post-test), and 3 months later (follow-up). The study population included 34 patients with a mean age of 35.5 years. Statistical comparison of memory assessments at 3-month follow-up showed significantly higher scores in the CR group than in the control group (93.33 vs 86.40 for Addenbrooke's Cognitive Examination test and 16.58 vs 12.00 for visual memory, 19.32 vs 14.05 for verbal memory, and 51.28 vs 44.41 for general scores on the Memory Functioning Questionnaire test, respectively). Wisconsin card sorting test score comparison showed significantly lower total time consumption in the CR group than in the control group (308.1 vs 340.8 seconds, respectively). Behavior rating inventory of executive function-adult scores in all four subtests were significantly higher in the CR group than in the control group (40.25 vs 55.4 for behavioral regulation index, 51.16 vs 68.6 for metacognition index, and 97.41 vs 124.00 for global executive composite, respectively). Attention was the only domain in which we did not observe any significant variation between groups in terms of post-test and follow-up scores. This study supports the efficacy of group CR in the improvement of cognitive function in patients with MS. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To evaluate and compare retention and caries occurance following placement of Clinpro and FUJI VII fissure sealants, by two different techniques simultaneously in unsealed, contralateral young permanent molars of 7- to 10-year-old children affected by mild to moderate dental fluorosis at various recall intervals of 1 week, 1, 3, 6 and 12 months. 80 schoolchildren with mild to moderate dental fluorosis were assigned to Group A and Group B with 40 children in each group. In Group A Clinpro fissure sealant and in Group B Fuji VII fissure sealant was used. In both the groups fissure sealants were applied by conventional fissure sealant technique (CST) on one side and enameloplasty sealant technique (EST) on the other side of the same arch. The applied fissure sealants were evaluated clinically for retention and caries incidence. Clinpro fissure sealant showed a retention rate of 95% when compared with Fuji VII (57.5%) at the end of 12 months, which was statistically significant. Regarding techniques, EST showed better results than CST in both the groups. Comparison of groups with respect to retention and techniques at different time periods was performed using Mann-Whitney U test (p < 0.05). Comparison of different time periods with respect to retention and technique in all the groups was performed using Wilcoxon matched pairs test by ranks (p < 0.05). Clinpro fissure sealant showed better retention at all treatment intervals, when compared with Fuji VII. Further follow-up is required to study the efficacy of the fissure sealant placement techniques.

Purpose: To compare the outcomes such as postoperative nausea/vomiting, analgesic requirements, and hospital stay following the use of topical oxybuprocaine hydrochloride 0.4% or intravenous (IV) fentanyl in children undergoing strabismus surgery. Methods: This was a prospective cohort study. Children operated under general anesthesia for strabismus were given topical oxybuprocaine hydrochloride 0.4% (Group T) and IV fentanyl (Group F) before surgery. The episodes of nausea/vomiting, pain score, requirement of additional analgesia during postoperative period, and duration of hospital stay were compared in two groups. Results: There were 47 children in Group T and 59 children in Group F. The median pain score in two groups were 2.38 (25% quartile; 2.0) and 3.00 (25% quartile; 3.00), respectively. The difference was significant (K W P < 0.03). The episodes of nausea/vomiting in two groups were in 2 and 6 children in Group T and Group F, respectively. The median hospital stay of children of Group T and Group F were 242 and 285 min, respectively. The difference was not statistically significant (P = 0.22). Conclusions: Using intraoperative topical oxybuprocaine drops, one can achieve better analgesic outcomes and reduce risk of nausea and vomiting compared to intravenous opioid analgesics and therefore, the hospital stay could also be marginally reduced.

In this randomized, blinded, multicenter comparison study, 377 infants and children with acute otitis media (AOM) received a 10-day course of an oral suspension of one of the following: cefuroxime axetil (CAE), 30 mg/kg/day; cefaclor (CEC), 40 mg/kg/day; or amoxicillin-clavulanate potassium (AMX-CL), 40 mg/kg/day. Clinical efficacy was determined by pneumatic otoscopy and tympanometric testing 3 to 5, 11 to 14, and 22 to 26 days after the initiation of therapy. There was a statistically significant difference among the three treatment groups with respect to clinical outcome; more patients in the CAE group (62%) than in the CEC group (46%) or the AMX-CL group (52%) had complete resolution of signs and symptoms of AOM (including effusion). Paired comparisons revealed a significant difference in efficacy between CAE and CEC and a nearly significant difference between AMX-CL and CEC. Taste acceptability was highest for CEC and lowest for this formulation of CAE. Significantly more patients in the AMX-CL group than in the CAE or CEC group had a side effect, primarily diarrhea, vomiting, or diaper rash. We conclude that CAE suspension has greater clinical efficacy than CEC and fewer side effects than AMX-CL.

To compare the difference between J-hook and micro-implant anchorage in the treatment of patient with bimaxillary protrusion. Thirty patients with bimaxillary protrusion were divided into two groups (J-hook and micro-implant groups) and treated with MBT appliance. Four first premolars were extracted in all patients. Cephalometric analyses were carried out before and after treatment. In J-hook group and micro-implant group,computerized cephalometric analysis revealed that before treatment U6C-PP was (12.4 +/- 0.2) mm and (12.5 +/- 0.1) mm, respectively,and after treatment U6C-PP was (12.6 +/- 0.1) mm and (12.8 +/- 0.1) mm,respectively. The difference between J-hook group and microimplant group was significant (P < 0.01). The other differences of cephalometric analyses between J-hook group and micro-implant group was not significant. Both J-hook and micro-implant could provide adequate anchorage in the treatment of patients with bimaxillary protrusion.

AIM: To investigate the role of growth hormone (GH), hyperbaric oxygen therapy (HBOT) and combined therapy on the intestinal neomucosa formation of the gastric serosa. METHODS: Forty-eight male Wistar-albino rats, weighing 250-280 g, were used in this study. The rats were divided into four groups (n = 12): Group 1, control, gastric serosal patch; Group 2, gastric serosal patch + GH; Group 3, gastric serosal patch + HBOT; and Group 4, gastric serosal patch + GH + HBOT. Abdominal access was achieved through a midline incision, and after the 1-cm-long defect was created in the jejunum, a 1 cm × 1 cm patch of the gastric corpus was anastomosed to the jejunal defect. Venous blood samples were taken to determine the insulin-like growth factor 1 (IGF-1) and insulin-like growth factor binding protein 3 (IGFBP-3) basal levels. HBOT was performed in Groups 3 and 4. In Groups 2 and 4, human GH was given subcutaneously at a dose of 2 mg per kg/d for 28 d, beginning on the operation day. All animals were sacrificed 60 d after surgery. The jejunal segment and the gastric anastomotic area were excised for histological examination. The inflammatory process, granulation, collagen deposition and fibroblast activity at the neomucosa formation were studied and scored. Additionally, the villus density, villus height, and crypt depth were counted and recorded. The measurements of villus height and crypt depth were calculated with an ocular micrometer. New vessel growth was determined by calculatingeach new vessel in a 1 mm2 area. RESULTS: In the histological comparison of groups, no significant differences were observed between the control group and Groups 2 and 3 with respect to epithelialization, granulation, fibroblastic activity and the inflammatory process, but significant differences were present between the control group and all others groups (Groups 2-4) with respect to angiogenesis (P < 0.01) and collagen deposition (P < 0.05, P < 0.01). Significant differences between the control group and Group 4 were also observed with respect to epithelialization and fibroblastic activity (P < 0.01 and P < 0.05, respectively). There were significant differences in villus density in all of groups compared with the control group (P < 0.05). Crypt depth was significantly greater in Group 4 than in the control group (P < 0.05), but no other groups had deeper crypts. However, villus height was significantly longer in Groups 2 and 4 than in the control group (P < 0.05). The comparison of groups revealed, significant difference between control group and Groups 2 and 4) with respect to the levels of IGF-1 and IGFBP-3 (P < 0.01) 3 wk after the operation. CONCLUSION: HBOT or GH and combined therapy augmented on neomucosal formation. The use of combined therapy produced a synergistic effect on the histological, morphological and functional parameters.

Video-assisted thoracoscopic surgery (VATS) represents at present the most suitable treatment of recurrent spontaneous pneumothorax. After three years we consider this interesting to draw up a trial balance of our VATS experience in comparison with the cases treated before 1991 with the classic thoracotomic approach. We have considered retrospectively the results obtained in a series of 30 consecutive patients with recurrent spontaneous pneumothorax treated with VATS between November 1991 and August 1994 in comparison with those obtained in a group of 30 patients previously treated with a traditional thoracotomy. The groups have been selected in such a way that surgical indications, sex ratio, age and number of episodes were homogeneous. The parameters we have compared were the postoperative complications, the duration of chest drainage and hospitalization, the operating times and the relapses. Besides these technical parameters we considered the economic data too. On average drains removal occurred one day before in VATS-Group: the time spent in the Hospital was significantly shorter in VATS-Group, being on average 1 week. Short term complications may be considered similar in the two Groups. Prolonged air leaks occurred in 13% and 16% respectively. Emothorax requesting reoperation occurred in 1 case for each Group. One death occurred in thoracotomy-Group in an old patient presenting a severe chronic respiratory insufficience with exacerbation in postoperative time. We have registered 2 relapses after VATS and none after thoracotomy. The study has demonstrated the therapeutic efficacy of VATS and in the same time that in VATS the total economic cost is lower (22.7%) in comparison with traditional thoracotomy.

Comparison of clinical and biochemical markers of dehydration with the clinical dehydration scale in children: a case comparison trial

PubMed Central

2014-01-01

Background The clinical dehydration scale (CDS) is a quick, easy-to-use tool with 4 clinical items and a score of 1–8 that serves to classify dehydration in children with gastroenteritis as no, some or moderate/severe dehydration. Studies validating the CDS (Friedman JN) with a comparison group remain elusive. We hypothesized that the CDS correlates with a wide spectrum of established markers of dehydration, making it an appropriate and easy-to-use clinical tool. Methods This study was designed as a prospective double-cohort trial in a single tertiary care center. Children with diarrhea and vomiting, who clinically required intravenous fluids for rehydration, were compared with minor trauma patients who required intravenous needling for conscious sedation. We compared the CDS with clinical and urinary markers (urinary electrolytes, proteins, ratios and fractional excretions) for dehydration in both groups using receiver operating characteristic (ROC) curves to determine the area under the curve (AUC). Results We enrolled 73 children (male = 36) in the dehydration group and 143 (male = 105) in the comparison group. Median age was 32 months (range 3–214) in the dehydration and 96 months (range 2.6-214 months, p < 0.0001) in the trauma group. Median CDS was 3 (range 0–8) within the dehydration group and 0 in the comparison group (p < 0.0001). The following parameters were statistically significant (p < 0.05) between the comparison group and the dehydrated group: difference in heart rate, diastolic blood pressure, urine sodium/potassium ratio, urine sodium, fractional sodium excretion, serum bicarbonate, and creatinine measurements. The best markers for dehydration were urine Na and serum bicarbonate (ROC AUC = 0.798 and 0.821, respectively). CDS was most closely correlated with serum bicarbonate (Pearson r = -0.3696, p = 0.002). Conclusion Although serum bicarbonate is not the gold standard for dehydration, this study provides further evidence for the usefulness of the CDS as a dehydration marker in children.

To evaluate acquired color vision deficiency in glaucoma by using the Rabin cone contrast test (RCCT). Twenty-seven eyes of 27 patients with glaucoma (glaucoma group) and 27 eyes of 27 normal subjects (control group) were included in this study. Long (L), medium (M), and short (S) CCT scores (L CCTs, M CCTs, and S CCTs, respectively) were measured using the RCCT in both groups. Visual field examinations were performed with Humphrey automated perimetry using the Swedish interactive thresholding algorithm 30-2, and the mean deviation (MD) was evaluated. The macular ganglion cell/inner plexiform layer (GCIPL) thickness was measured using high-definition optical coherence tomography in the glaucoma group. The mean M CCTs and S CCTs in the glaucoma group were significantly lower (P<0.05 for both comparisons) than in the control group (M CCTs, 80.7±16.8 vs. 91.9±8.22; S CCTs, 83.9±19.5 vs. 97.4±3.77, respectively); the L CCTs did not differ significantly (P=0.065) from those of the controls (91.8±12.8 vs. 97.4±3.50, respectively). The M CCTs and S CCTs were correlated significantly with those of MD (M CCTs, r=0.47; S CCTs, r=0.44; P<0.05 for both comparisons) and GCIPL thickness (M CCTs, r=0.70; P<0.0001; S CCTs, r=0.57; P<0.01). The chromatic discrimination thresholds measured by RCCT in the glaucoma group were significantly different from those measured in the control group and were correlated with the MD and GCIPL thickness. The RCCT may be useful for evaluating acquired color vision deficiency in glaucoma and may help advance current understanding of the pathophysiology of glaucomatous damage.

Communication campaigns might be a viable means of improving contraceptive continuation; however, few such interventions aimed at reducing contraceptive discontinuation have been evaluated. Data were collected from independent samples of new injectable users in Nyando District, Kenya-site of a communication campaign to increase contraceptive continuation-and in a comparison district, nine months before and nine months after intervention implementation. Survival analysis was used to compare the intervention and comparison groups with respect to the distribution of time until first discontinuation of modern method use among women still in need of family planning. Exposure to family planning information was high in both the treatment and the comparison district before (97% and 85%, respectively) and after the intervention (99% and 78%). Postintervention, 5% of women in the comparison district discontinued by 98 days, 8% by 196 days and 23% by 294 days; the proportions in the treatment district were 4%, 6% and 16%, respectively. No significant difference between the districts was found in the ninemonth postintervention contraceptive continuation rates. Having method-related side effects or health concerns was the reason most consistently associated with discontinuation. Other factors associated with discontinuation differed between the districts. Addressing method-related side effects and health concerns will be critical in improving continuation of the injectable.

There is no standard immunoassay for evaluating immune responses to meningococcal vaccines. We developed an enzyme-linked immunosorbent assay to measure total levels of antibody to Neisseria meningitidis group A capsular polysaccharide. Five laboratories measured the antibody levels in six paired pre- and postvaccination serum samples by using the enzyme-linked immunosorbent assay. Methylated human serum albumin was used to bind native group A polysaccharide to microtiter plate surfaces. The between-laboratory coefficients of variation for pre- and postvaccination sera had ranges of 31 to 91 and 17 to 31, respectively. The mean laboratory coefficients of variation for pre- and postvaccination sera, respectively, were 17 and 11 (Molecular Biology Laboratory, Centers for Disease Control), 12 and 15 (Immunodiagnostic Methods Laboratory, Centers for Disease Control), 22 and 19 (Dana-Farber Cancer Institute), 38 and 38 (Bacterial Polysaccharide Laboratory, U.S. Food and Drug Administration), and 11 and 10 (Praxis Biologics, Inc.). Standardization of this enzyme-linked immunosorbent assay should allow interlaboratory comparison of meningococcal vaccine immunogenicity, thus providing a laboratory-based assessment tool for evaluating meningococcal vaccines.

Photonic crystal waveguides are optimized for modal confinement and loss related to slow light with high group index. A detailed comparison between optimized circular-hole based waveguides and optimized waveguides with free topology is performed. Design robustness with respect to manufacturing imperfections is enforced by considering different design realizations generated from under-, standard- and over-etching processes in the optimization procedure. A constraint ensures a certain modal confinement, and loss related to slow light with high group index is indirectly treated by penalizing field energy located in air regions. It is demonstrated that slow light with a group index up to ng = 278 can be achieved by topology optimized waveguides with promising modal confinement and restricted group-velocity-dispersion. All the topology optimized waveguides achieve a normalized group-index bandwidth of 0.48 or above. The comparisons between circular-hole based designs and topology optimized designs illustrate that the former can be efficient for dispersion engineering but that larger improvements are possible if irregular geometries are allowed.

Background: There is the controversy concerning the main component of tobacco, which is responsible for its arrhythmogenesis. In addition, there is the lack of adequate information about the influence of combination of black tea and nicotine on heart rhythm. Objectives: This study aimed to examine whether pretreatment with black tea and nicotine could modulate the susceptibility to lethal ventricular arrhythmias. Materials and Methods: Animals were randomized to control, black tea, nicotine, and black tea plus nicotine groups. Test groups were treated with black tea brewed (orally) and nicotine (2 mg/kg, subcutaneous), alone and in combination for four weeks. On day 29, aconitine was infused intravenously for induction of cardiac arrhythmia. Results: In comparison with the control group, each of tea and nicotine significantly decreased the duration of the ventricular tachycardia (VT) plus ventricular fibrillation (VF) and the score of arrhythmia severity (P < 0.05 and P < 0.01, respectively,). The latency for the first VT event was significantly longer in the all test groups, but VF latency was significant only in tea and nicotine groups compared with control group (P < 0.05 and P < 0.01, respectively).Threshold dose of aconitine for inducing VT and VF increased in all test groups, but only VT showed a significant difference in comparison to the control group (P < 0.001). Conclusions: The findings suggest that sub-chronic consumption of nicotine or black tea alone with appropriate doses could potentially be antiarrhythmic and its combination regimen does not increase the risk of fatal ventricular arrhythmias during four-week consumption period in rats.

The aim of this work was to study the specificity of deficits in linguistic and executive functioning of students with ADHD and with RCD and to determine the profile of deficits in the comorbid group (ADHD+RCD). Participants in the study were 84 students, ages 12-16 years divided into four groups with an equal number of subjects (N= 21): ADHD, RCD, ADHD+RCD and comparison group (without ADHD and without RCD). We measured vocabulary, oral comprehension, lexical access, verbal and visual working memory, inhibition and attention. The results show that the ADHD+RCD group presents the most important linguistic deficits, followed by the RCD group. On the other hand, the three clinical groups (ADHD, RCD and ADHD+RCD) display greater performance problems in working memory than the comparison group, whereas the two groups with ADHD had more problems in attention and inhibition. These results suggest the dissociation of linguistic and executive deficits that affect the RCD group and ADHD group to a greater extent, respectively. Lastly, the comorbid group showed deficits both in language and in executive skills. We discuss the implications of these findings for designing interventions.

Chemokine CX3CL1 (fractalkine) may be an important factor linking thyroid status and bone remodeling, through tetrac, a derivative of thyroxine. This study explores the relationship between serum fractalkine levels and parameters of thyroid status and bone in premenopausal women with Graves' disease (GD) in comparison to healthy controls. This cross-sectional study included three premenopausal female groups: active GD; cured GD, and healthy age-, gender-, and BMI-matched controls. Measurement of serum fractalkine levels (Quantikine ® ELISA), total amino-terminal peptide of procollagen type 1 (P1NP), CTx, thyroid hormones, BMD and trabecular bone score (TBS) were performed in all study subjects. Sixty women (21, 16, and 23 in active GD, cured GD, and healthy control groups, respectively) were included. Serum fractalkine levels were higher (p<0.05) in active and cured GD subjects compared to healthy controls (mean 0.7±0.14; 0.93±0.15, and 0.48±0.13 ng/ml, respectively). Lumbar spine BMD was lowest in the cured GD group in comparison to active GD and control group subjects (0.926±0.03; 1.016±0.03; 1.051±0.03 g/cm 2 ; p<0.05, respectively). TBS was lower (p<0.05) in both GD groups than controls being lowest in those with active GD (1.395±0.02; 1.402±0.02, 1.469±0.02, respectively). Serum fractalkine concentration was positively correlated with fT4, and negatively correlated with TBS values. GD in pre-menopausal females is associated with increased serum fractalkine concentration and decreased TBS. Fractalkine may be a currently unappreciated link between hyperthyroidism and bone; further research into this possibility is needed. © Georg Thieme Verlag KG Stuttgart · New York.

The present results demonstrate that a small implant size, undercorrection of the vocal fold, antero-posterior implant malposition, and the use of expanded polytetrafluoroethylene (ePTFE) are the primary factors that cause a poor outcome of medialization thyroplasty (MT). To assess the postoperative laryngeal condition using computed tomography (CT) in patients with unilateral vocal fold paralysis who underwent MT alone, and to identify the primary causal factors in terms of the surgical procedures that affect the outcomes of MT. Twenty-two patients who underwent MT alone were divided into two groups based on either the maximal phonation time or the perceived vocal breathiness. Two laryngologists assessed the postoperative laryngeal CT images during sustained vowel phonation and judged whether there were abnormalities of the arytenoid cartilage position, window position, implant size, and implant position, as well as the degree of correction of the vocal fold. As implant material, a silicone block, ePTFE, and hydroxyapatite had been inserted in 2, 9, and 11 patients, respectively. Comparisons of the prevalence of abnormalities in the abovementioned factors between the different outcomes and between the types of material used for the implant were performed. Twelve patients with a poor outcome and 10 with a good outcome showed 36 and 18 abnormal findings identified by either of the two laryngologists, respectively. In the poor outcome group, a smaller implant size and undercorrection of the vocal fold showed both high kappa values and a significantly higher prevalence than those in the good outcome group (p < 0.001 and p < 0.05), respectively. The comparison between material types demonstrated that the sheet-like material (ePTFE) group exhibited a significantly higher prevalence of undercorrection than the block-like material group (p < 0.05).

Academic examination is a major stressor for students in China. Investigation of stress-sensitive endocrine responses to major examination stress serves as a good model of naturalistic chronic psychological stress in an otherwise healthy population. The cortisol awakening response (CAR) is an endocrine marker of the hypothalamic-pituitary-adrenocortical (HPA) axis in response to stress. However, it remains unknown how chronic examination stress impacts the CAR in a young healthy population To exclude the influence of sex effects on hormone level, the CAR and psychological stress responses were assessed on two consecutive workdays in 42 male participants during their preparations for the Chinese National Postgraduate Entrance Exam (NPEE) and 21 non-exam, age-matched male comparisons. On each day, four saliva samples were collected immediately after awakening, 15 minutes, 30 minutes and 60 minutes after awakening. The waking level (S1), the increase within 30 minutes after awakening (R30), the area under the curve with respect to ground (AUCg), and the area under the curve with respect to increase (AUCi) were used to quantify the CAR. Psychological stress and anxiety were assessed by the Perceived Stress Scale and the Spielberger State-Trait Anxiety Inventory, respectively. Male participants in the exam group had greater perceived stress and anxiety scores relatibe to the non-exam group. Both R30 and AUCi in the exam group were significantly lower than the comparison group and this effect was most pronounced for participants with high levels of perceived stress in the exam group. Perceived stress and anxiety levels were negatively correlated with both R30 and AUCi. Chronic examination stress can lead to the decrease of CAR in healthy young men, possibly due to reduced HPA axis activity under long-term sustained stress.

This study evaluated how the Hypertension Disease Management Program (HDMP) affects patient's blood pressure, knowledge, health behaviors, and use of medical services. Evaluation was performed by 2 measures, which were before and after comparison within the management group (n = 210) and comparison between the management group and control group (n = 1050) in 2005. Systolic and diastolic blood pressure of management group significantly decreased from 137.5 and 86.0 mm Hg to 131.2 and 83.8 mm Hg (P < .001, P < .01), respectively. Dieting, snack control, consumption of low-sodium meals, low-cholesterol meals, and fruits or vegetables, regular checking of blood pressure, and stress management techniques significantly increased after HDMP. However, there was no significant difference in the use of medical service between the disease management group and the control group. This study showed that the HDMP improved lifestyle and reduced blood pressure on the disease management group, but changed neither medical costs nor use of medical services. Long-term evaluation should be performed to determine if the HDMP reduce medical costs and use of medical services.

Three groups of Ugandan children (20 in each group) and one comparison group of 20 children were examined between 11 and 17 years of age. The first three groups had been admitted to hospital for treatment of protein energy malnutrition between the ages of eight to 15, 16 to 21 and 22 to 27 months, respectively. The comparison group had not been clinically malnourished throughout the whole period up to 27 months of age. All the children came from one tribe and were individually matched for sex, age, education and home environment. It was found that the three malnourished groups fell significantly below the comparison group in anthropometric measurements and in tests of intellectual and motor abilities. No evidence was found for a relationship between the deficit and age at admission. Further analysis among the 60 malnourished children revealed that anthropometry and intellectual and motor abilities are the more affected the greater the degree of 'chronic undernutrition' at admission, but no correlation was found with the severity of the 'acute malnutrition'. The results show a general impairment of intellectual abilities, with reasoning and spatial abilities most affected, memory and rote learning intermediately and language ability least, if at all, affected. These findings are discussed in the context of a comprehensive and critical appraisal of the existing literature.

To explore the effect of in-home fortification of complementary feeding on intellectual development of Chinese children aged below 24 months. One thousand and four hundred seventy eight children aged 4-12 months were recruited and divided into study groups (formula 1 group and formula 2 group) and control group. In two study groups, in addition to the usual complementary food, children were fed with a sachet of fortified food supplement each day. Protein and micronutrients were provided in formula 1 group. Formula 2 group had the same energy intake as the formula 1 group . In addition to measurement of physical growth and detection of hemoglobin level, Development Quotient (DQ) or Intelligence Quotient (IQ) was assessed. The DQ of children aged below 24 months was 97.2, 95.5, and 93.8 in formula 1 group, formula 2 group and control group, respectively, and the differences were statistically significant (P < 0.05). The DQ of children in formula 1 group, formula 2 group, and control group was 92.7, 90.4, and 88.3 respectively in the first follow up showing statistically significant differences (P < 0.05). And, DQ of children in formula 1 group, formula 2 group and control group were 96.7, 94.5, and 93.7 respectively in the second follow up, showing statistically significant differences (P < 0.05). Full-IQ of children in the formula 1 group was 3.1 and 4.5 points higher than that in formula 2 group and in control group respectively. Verbal IQ of children in the formula 1 group was 2.1 and 5 points higher than that in formula 2 group and control group respectively. Performance IQ was 2.5 and 3.1 points higher than that in formula 2 group and control group respectively. All above mentioned comparisons were statistically significant. Fortification of complementary feeding showed persistent effect on intelligence development of young children which could persist to 6 years of age. The critical time for correction of anemia could be under 18 months.

Introduction Communication skills training, responsibility, respect, and self-awareness are important indexes of changing learning behaviours in modern approaches. Aim The aim of this study was to investigate the efficacy of three learning approaches, collaborative, context-based learning (CBL), and traditional, on learning, attitude, and behaviour of undergraduate nursing students. Materials and Methods This study was a clinical trial with pretest and post-test of control group. The participants were senior nursing students. The samples were randomly assigned to three groups; CBL, collaborative, and traditional. To gather data a standard questionnaire of students’ behaviour and attitude was administered prior to and after the intervention. Also, the rate of learning was investigated by a researcher-developed questionnaire prior to and after the intervention in the three groups. Results In CBL and collaborative training groups, the mean score of behaviour and attitude increased after the intervention. But no significant association was obtained between the mean scores of behaviour and attitude prior to and after the intervention in the traditional group. However, the mean learning score increased significantly in the CBL, collaborative, and traditional groups after the study in comparison to before the study. Conclusion Both CBL and collaborative approaches were useful in terms of increased respect, self-awareness, self-evaluation, communication skills and responsibility as well as increased motivation and learning score in comparison to traditional method.

Objective: The aim of this study was to compare the shear bond strength (SBS) of resin modified glass ionomer (RMGI) and composite resin for bonding metal and ceramic brackets. Materials and Methods: Eighty-eight human premolars extracted for orthodontic purposes were divided into 4 groups (n=22). In groups 1 and 2, 22 metal and ceramic brackets were bonded using composite resin (Transbond XT), respectively. Twenty-two metal and ceramic brackets in groups 3 and 4, respectively were bonded using RMGI (Fuji Ortho LC, Japan). After photo polymerization, the teeth were stored in water and thermocycled (500 cycles between 5° and 55°). The SBS value of each sample was determined using a Universal Testing Machine. The amount of residual adhesive remaining on each tooth was evaluated under a stereomicroscope. Statistical analyses were done using two-way ANOVA. Results: RMGI bonded brackets had significantly lower SBS value compared to composite resin bonded groups. No statistically significant difference was observed between metal and ceramic brackets bonded with either the RMGI or composite resin. The comparison of the adhesive remnant index (ARI) scores between the groups indicated that the bracket failure mode was significantly different among groups (P<0.001) with more adhesive remaining on the teeth bonded with composite resin. Conclusion: RMGIs have significantly lower SBS compared to composite resin for orthodontic bonding purposes; however the provided SBS is still within the clinically acceptable range. PMID:25628663

Early nutrition is critical for later health and sustainable development. We determined potential effectiveness of the Kenyan Community Health Strategy in promoting exclusive breastfeeding (EBF) in urban poor settings in Nairobi, Kenya. We used a quasi-experimental study design, based on three studies [Pre-intervention (2007-2011; n=5824), Intervention (2012-2015; n=1110) and Comparison (2012-2014; n=487)], which followed mother-child pairs longitudinally to establish EBF rates from 0 to 6 months. The Maternal, Infant and Young Child Nutrition (MIYCN) study was a cluster randomized trial; the control arm (MIYCN-Control) received standard care involving community health workers (CHWs) visits for counselling on antenatal and postnatal care. The intervention arm (MIYCN-Intervention) received standard care and regular MIYCN counselling by trained CHWs. Both groups received MIYCN information materials. We tested differences in EBF rates from 0 to 6 months among four study groups (Pre-intervention, MIYCN-Intervention, MIYCN-Control and Comparison) using a χ(2) test and logistic regression. At 6 months, the prevalence of EBF was 2% in the Pre-intervention group compared with 55% in the MIYCN-Intervention group, 55% in the MIYCN-Control group and 3% in the Comparison group (P<0.05). After adjusting for baseline characteristics, the odds ratio for EBF from birth to 6 months was 66.9 (95% CI 45.4-96.4), 84.3 (95% CI 40.7-174.6) and 3.9 (95% CI 1.8-8.4) for the MIYCN-Intervention, MIYCN-Control and Comparison group, respectively, compared with the Pre-intervention group. There is potential effectiveness of the Kenya national Community Health Strategy in promoting EBF in urban poor settings where health care access is limited.

Comparison of effectiveness and safety of ultramini percutaneous nephrolithotomy (UMPNL) and retrograde intrarenal surgery (RIRS) in treatment of moderate-sized renal stones. The patients scheduled for surgery attributable to renal stones with the greatest diameter of 10 to 25 mm were prospectively analyzed. Patients were randomized into groups with tossing a coin method. The patients who had UMPNL and RIRS were defined as Group I and Group II, respectively. The groups were compared for demograhic data, stone characteristics, operative and postoperative data, stone-free status, and the complications. Student's t-test and Pearson's Chi square tests were used for statistical analysis. p < 0.05 was considered as statistically significant. There were 30 patients in Group I, and 43 patients in Group II. The groups were similar for age, gender, side of the stone, and surface area characteristics of the stone (p = 0.194, p = 0.470, p = 0.990, and p = 0.487, respectively). Stone-free rate was 80% (n = 24) in UMPNL, and 74.4% (n = 32) in RIRS (p = 0.579). Modified Clavien Classification Grade 1 to 2 and 3A to 3B complications were similar in two groups (p = 0.959 and p = 0.192, respectively). Comparison of stone-free rates was 93.3% in UMPNL, and 42.9% in RIRS groups for lower pole stones (p = 0.009). Groups I and II were significantly different for visual analog scale scores for postoperative pain (4.73 ± 1.25 vs 2.30 ± 1.12), hospital stay (2.46 ± 3.02 vs 1.37 ± 1.48 days), and time to return to normal daily life (11.26 ± 5.55 vs 6.65 ± 4.30 days) (p < 0.001, p < 0.001, and p < 0.001, respectively). Both UMPNL and RIRS procedures are effective and safe methods in treatment of middle-sized renal stones. However, UMPNL is more effective than RIRS in treatment of lower pole stones. RIRS is more advantageous when loss from work is taken into consideration.

The purpose of this study was to investigate the efficacy and safety of the administration of retinol palmitate (VApal) ophthalmic solution (500 IU/mL) for the treatment of patients with dry eye. This study included 66 patients with dry eye. After a 2-week washout period, patients were randomized (1:1) into either a VApal ophthalmic solution or a placebo group, and a single drop of either solution was administered six times daily for 4 weeks. Efficacy measures were 12 subjective symptoms, rose bengal (RB) and fluorescein staining scores, tear film breakup time, and tear secretion. Safety measures included clinical blood and urine analyses and adverse event recordings. In comparisons of the two groups, the mean change in RB staining score from baseline was significantly lower in the VApal group at 2 and 4 weeks ( P <0.05 and P <0.01, respectively). Furthermore, the fluorescein clearance rate (fluorescein staining score) was significantly higher in the VApal group at 4 weeks ( P <0.05). The VApal group showed a significant improvement in blurred vision at 1 and 2 weeks ( P <0.01 and P <0.05, respectively), and the mean change in the total score for subjective symptoms from baseline was significantly lower in the VApal group at 1 week ( P <0.05). In before- and after-intervention comparisons, the fluorescein and RB staining scores showed improvement in both groups. Improvement was noted for 11 subjective symptoms in the VApal group and for seven symptoms in the placebo group. No significant differences in adverse events and reactions were found between the groups. VApal ophthalmic solution (500 IU/mL) is safe and effective for the treatment of patients with dry eye.

In the current study, we aimed to investigate the influences of pentoxifylline, which increases the flexibility, deformability and viscosity of the erythrocytes while reducing the aggregation abilities of the platelets, and vinpocetine, which has neuroprotective and antioxidant effects, on healing of colonic anastomoses. We used 30 Albino Wistar rats. Subjects were divided into three groups of 10 rats each. Colonic ischemia was established in all the groups. Following colonic transection, anastomosis was performed. Group A received intraperitoneal saline, whereas Group B and Group C received pentoxifylline and vinpocetine, respectively. The subjects were sacrificed on the postoperative 5th day by ether anesthesia, and their colonic bursting pressures were measured. The anastomotic area was excised for hydroxyproline assay and histopathologic examination. According to intergroup comparisons, colonic bursting pressure was found to be higher in the treatment groups than in the control group; however, the difference was not statistically significant. Intergroup comparisons regarding tissue hydroxyproline levels showed statistically significant differences between Groups A and B, Groups A and C and Groups B and C. Similar to pentoxifylline, vinpocetine was also shown to have a beneficial effect over ischemic colon anastomoses.

The developmental consequences in adulthood of growing up with childhood cancer are not well understood. The Course of life questionnaire was developed to assess the attainment of developmental milestones retrospectively and socio-demographic outcomes in young adulthood. The aim of this study was to assess the course of life and socio-demographic outcomes in young adult survivors of childhood cancer. Knowledge about possible gaps in the course of life could enable health care providers to aim for the most favourable course of life. A total of 353 Dutch survivors and a comparison group of 508 peers without a history of cancer, all aged between 18 and 30, filled in the Course of life questionnaire. The course of life of the survivors was found to be hampered. The young adult survivors of childhood cancer in the Netherlands turned out to have achieved fewer milestones than their peers with respect to autonomy development, social development, and psycho-sexual development, or to have achieved the milestones when they were older than their peers. In addition, survivors displayed less risk behaviour than the comparison group. The survivors and the comparison group also differed on some socio-demographic issues. A considerably lower percentage of survivors than peers in the comparison group were married or living together, and/or employed. Their educational level, on the other hand, was as high as that of their peers. Copyright 2004 John Wiley & Sons, Ltd.

The aim of this study was to compare the effect of different modes of toothbrushing education (lecture, video and pamphlet) on the dental plaque index (PI) of adolescents. The cluster randomized intervention was performed on 128 participants aged 12 years, who were allocated into four groups based on the type of intervention. Group 1: no intervention; and groups 2, 3, 4: education via lecture, video, and pamphlet, respectively (n = 32). Their plaque index was measured at the baseline, 24 h and two months later. Data were analyzed by repeated measures analysis of variance (ANOVA), one-way ANOVA, independent and paired t-test. The plaque indices of groups 2, 3, 4 at 24 h (p values < 0.001) and two months (p values < 0.001) showed a significant reduction when compared to the baseline. The lowest PI score was observed in the pamphlet, video and lecture groups at 24 h, respectively. After 2 months, the lowest score of PI was measured in lecture, video and pamphlet groups, respectively; however, these differences were non-significant. Therefore, toothbrushing education via lecture, video and pamphlet reduced the dental plaque index with the same effectiveness.

Abstract Evaluation of chronic care management (CCM) programs is necessary to determine the behavioral, clinical, and financial value of the programs. Financial outcomes of members who are exposed to interventions (treatment group) typically are compared to those not exposed (comparison group) in a quasi-experimental study design. However, because member assignment is not randomized, outcomes reported from these designs may be biased or inefficient if study groups are not comparable or balanced prior to analysis. Two matching techniques used to achieve balanced groups are Propensity Score Matching (PSM) and Coarsened Exact Matching (CEM). Unlike PSM, CEM has been shown to yield estimates of causal (program) effects that are lowest in variance and bias for any given sample size. The objective of this case study was to provide a comprehensive comparison of these 2 matching methods within an evaluation of a CCM program administered to a large health plan during a 2-year time period. Descriptive and statistical methods were used to assess the level of balance between comparison and treatment members pre matching. Compared with PSM, CEM retained more members, achieved better balance between matched members, and resulted in a statistically insignificant Wald test statistic for group aggregation. In terms of program performance, the results showed an overall higher medical cost savings among treatment members matched using CEM compared with those matched using PSM (-$25.57 versus -$19.78, respectively). Collectively, the results suggest CEM is a viable alternative, if not the most appropriate matching method, to apply when evaluating CCM program performance.

Purpose: Esophagectomy remains the mainstay treatment for esophageal cancer, although retrospective studies have suggested that chemoradiotherapy (CRT) is as effective as surgery. To determine whether CRT can substitute for surgery as the primary treatment modality, we performed a prospective direct comparison of outcomes after treatment in patients with resectable esophageal cancer who had received CRT and those who had undergone surgery. Methods and Materials: Eligible patients had resectable T1-3N0-1M0 thoracic esophageal cancer. After the surgeon explained the treatments in detail, the patients selected either CRT (CRT group) or surgery (OP group). The CRT course consisted of two cycles of cisplatinmore » and fluorouracil with split-course concurrent radiotherapy of 60Gy in 30 fractions. Patients with progressive disease during CRT and/or with persistent or recurrent disease after CRT underwent salvage resection. Results: Of 99 eligible patients with squamous cell carcinoma registered between January 2001 and December 2005, 51 selected CRT and 48 selected surgery. Of the patients in the CRT group, 13 (25.5%) underwent esophagectomy as salvage therapy. The 3- and 5-year survival rates were 78.3% and 75.7%, respectively, in the CRT group compared with 56.9% and 50.9%, respectively, in the OP group (p = 0.0169). Patients in the OP group had significantly more metastatic recurrence than those in the CRT group. Conclusions: Treatment outcomes among patients with resectable thoracic esophageal squamous cell carcinoma were comparable or superior after CRT (with salvage therapy if needed) to outcomes after surgery alone.« less

Background Myocardial infarct size is a strong predictor of cardiovascular events. Intravenous metoprolol before coronary reperfusion has been shown to reduce infarct size; however, it is unknown whether oral metoprolol initiated early after reperfusion, as clinical guidelines recommend, is similarly cardioprotective. We compared the extent of myocardial salvage associated with intravenous pre-reperfusion-metoprolol administration in comparison with oral post-reperfusion-metoprolol or placebo. We also studied the effect on suspected markers of reperfusion injury. Methods Thirty Yorkshire-pigs underwent a reperfused myocardial infarction, being randomized to pre-reperfusion-metoprolol, post-reperfusion-metoprolol or placebo. Cardiac magnetic resonance imaging was performed in eighteen pigs at day 3 for the quantification of salvaged myocardium. The amounts of at-risk and infarcted myocardium were quantified using T2-weighted and post-contrast delayed enhancement imaging, respectively. Twelve animals were sacrificed after 24 h for reperfusion injury analysis. Results The pre-reperfusion-metoprolol group had significantly larger salvaged myocardium than the post-reperfusion-metoprolol or the placebo groups (31±4%, 13±6%, and 7±3% of myocardium at-risk respectively). Post-mortem analyses suggest lesser myocardial reperfusion injury in the pre-reperfusion-metoprolol in comparison with the other 2 groups (lower neutrophil infiltration, decreased myocardial apoptosis, and higher activation of the salvage-kinase phospho-Akt). Salvaged myocardium and reperfusion injury pair wise comparisons proved there were significant differences between the pre-reperfusion-metoprolol and the other 2 groups, but not among the latter two. Conclusions The intravenous administration of metoprolol before coronary reperfusion results in larger myocardial salvage than its oral administration initiated early after reperfusion. If confirmed in the clinical setting, the timing and route of β-blocker initiation could be revisited. PMID:19913314

Given poor use of recall in primary care practices, we compared outsourced versus office-based recall systems. From 2011 to 2013, we enrolled 87 individual Arkansas providers in distinct practices treating their own patients <24 months of age which were randomized to usual care (A), office-based (B), or outsourced (C) recall groups. At the end of study, recall activity was 19.4%, 55.0%, and 92.6% for Groups A, B, and C, respectively (B and C vs A: P < .001). Only 68 Group B patients were identified as needing immunizations versus 826 in Group C. The majority of successful contacts were made through mobile phone (41.3%) or text message (32.6%). The total cost per practice per week was significantly lower for Group C versus Group B ($39.50 and $53.00, respectively; P = .004). With limited electronic health record use, an outsourced recall system is more sustainable and less costly than an office-based system.

PURPOSE To compare the late complications in the Ahmed Baerveldt Comparison Study during 5 years of follow-up. DESIGN Multicenter, prospective, randomized clinical trial. METHODS SETTINGS Sixteen international clinical centers. STUDY POPULATION Two hundred seventy six subjects aged 18 to 85 years with previous intraocular surgery or refractory glaucoma with intraocular pressure of > 18 mmHg. INTERVENTIONS Ahmed Glaucoma Valve FP7 or Baerveldt Glaucoma Implant BG 101-350. MAIN OUTCOME MEASURES Late postoperative complications (beyond 3 months), reoperations for complications, and decreased vision from complications. RESULTS Late complications developed in 56 subjects (46.8 ± 4.8 5 year cumulative % ± SE) in the Ahmed Glaucoma Valve group and 67 (56.3 ± 4.7 5 year cumulative % ± SE) in the Baerveldt Glaucoma Implant group (P = 0.082). The cumulative rates of serious complications were 15.9% and 24.7% in the Ahmed Glaucoma Valve and Baerveldt Glaucoma Implant groups respectively (P = 0.034) although this was largely driven by subjects who had tube occlusions in the two groups (0.8% in the Ahmed Glaucoma Valve group and 5.7% in the Baerveldt Glaucoma Implant group, P = 0.037). Both groups had a relatively high incidence of persistent diplopia (12%) and corneal edema (20%), although half of the corneal edema cases were likely due to pre-existing causes other than the aqueous shunt. The incidence of tube erosion was 1% and 3% in the Ahmed Glaucoma Valve and Baerveldt Glaucoma Implant groups, respectively (P = 0.04). CONCLUSIONS Long term rates of vision threatening complications and complications resulting in reoperation were higher in the Baerveldt Glaucoma Implant than the Ahmed Glaucoma Valve group over 5 years of follow-up.

To compare the outcomes of flexible ureterorenoscopy (F-URS) and mini-percutaneous nephrolithotomy (mini-PNL) in the treatment of lower calyceal stones smaller than 2 cm. Patients who underwent F-URS and mini-PNL for the treatment of lower calyceal stones smaller than 2 cm between March 2009 and December 2014 were retrospectively evaluated. Ninety-four patients were divided into two groups by treatment modality: F-URS (Group 1: 63 patients) and mini-PNL (Group 2: 31 patients). All patients were preoperatively diagnosed with intravenous pyelography or computed tomography. Success rates for F-URS and mini-PNL at postoperative first month were 85.7% and 90.3%, respectively. Operation time, fluoroscopy time, and hospitalization time for F-URS and mini-PNL patients were 44.40 min, 2.9 min, 22.4 h, and 91.9 min, 6.4 min, and 63.8 h, respectively. All three parameters were significantly shorter among the F-URS group (p < 0.001). Postoperative hemoglobin drop was significantly lower in F-URS group compared to mini-PNL group (0.39 mg/dL vs. 1.15 mg/dL, p = 0.001). A comparison of complications according to the Clavien classification demonstrated significant differences between the groups (p = 0.001). More patients in the F-URS groups require antibiotics due to urinary tract infection, and more patients in the mini-PNL group required ureteral double J catheter insertion under general anesthesia. Although both F-URS and mini-PNL have similar success rates for the treatment of lower calyceal stones, F-URS appears to be more favorable due to shorter fluoroscopy and hospitalization times; and lower hemoglobin drops. Multicenter and studies using higher patient volumes are needed to confirm these findings.

The aim of this study is to determine and compare biometric and refractive characteristics of thalassemia major patients and normal individuals. In this cross-sectional study, 54 thalassemia major patients were selected randomly as case group, and 54 age- and sex-matched healthy subjects were regarded as control group. Refractive errors, corneal curvature and ocular components were measured by autokeratorefractometery and A-scan ultrasonography, respectively. Mean spherical equivalent was -0.0093 ± 0.86 D in thalassemia patients and -0.22 ± 1.33 D in the normal group. The prevalence of myopia, Hyperopia, and emmetropia among thalassemia patients was 16.7, 19.4, and 63.9 %, respectively. While in the control group, 26.9 % were myopic, 25 % were hyperopic, and 48.1 % were emmetropic. The prevalence of astigmatism in case group was 22.2 %, which was not significantly different from that in control group, (27.8 %, p = 0.346). Mean axial length in thalassemia patients was 22.89 ± 0.70 which was significantly lower than that in normal group (23.37 ± 0.91, p = 0.000). The flattest meridian of the cornea (R1) was significantly steeper in thalassemia patients (7.77 ± 0.24) in comparison to normal individuals (7.85 ± 0.28). Although thalassemic patients had significantly smaller axial length and vitreous chamber depth in comparison to normal group, which could be due to their abnormal physical growth, there was no significant difference between the mean of spherical equivalent among two groups. This can be due to their steeper corneal curvature that overcomes the refractive disadvantage of their shorter axial length.

The aim of the present study was to investigate and compare the effects of conventional Hyrax screw treatment and memory screw treatment on skeletal and dentoalveolar structures. Thirty-two patients with maxillary transversal deficiency were divided into two groups. The memory-screw group included 17 patients (nine females and eight males), while the Hyrax-screw group comprised 15 patients (eight females and seven males). Mean ages of the subjects in the memory-screw and Hyrax-screw groups were 13.00 ± 1.29 and 12.58 ± 1.50 years, respectively. Plaster models and postero-anterior cephalograms were taken from the patients at the beginning of the treatment (T1) and at the end of expansion (T2) and retention periods (T3). The mean expansion period was 7.76 ± 1.04 days in the memory-screw group and 35.46 ± 9.39 days in the Hyrax-screw group. 'Shapiro-Wilk Normality test' was used to determine whether the investigated parameters were homogeneous or not. To determine the treatment changes within the group, 'paired t-test' and 'Wilcoxon signed-ranks test' were applied to the homogeneous and non-homogeneous parameters, respectively. Comparison between the groups was carried out using 'Student's t-test' for homogeneous parameters and 'Mann-Whitney U-test' for the rest. Rapid maxillary expansion was carried out successfully in both the groups. However, the use of memory screw may be advantageous because it shortens the maxillary expansion period, provides additional expansion in the retention period, and generates light forces relative to the conventional Hyrax screw.

Prolongation of Q-Tc interval is commonly accepted as a surrogate marker for the ability of a drug to cause torsade de pointes. In the present study, safety of olanzapine versus risperidone was compared among a group of patients with schizophrenia to see the frequency of the electrocardiographic alterations induced by those atypical antipsychotics. Two hundred and sixty-eight female inpatients with schizophrenia entered in one of the two parallel groups to participate in an open study for random assignment to olanzapine (n = 148) or risperidone (n = 120). Standard 12-lead surface electrocardiogram (ECG) was taken from each patient at baseline, before initiation of treatment, and then at the end of management, just before discharge. The parameters that were assessed included heart rate (HR), P-R interval, QRS interval, Q-T interval (corrected = Q-Tc), ventricular activation time (VAT), ST segment, T wave, axis of QRS, and finally, interventricular conduction process. A total of 37.83% of cases in the olanzapine group and 30% in the risperidone group showed some Q-Tc changes; 13.51% and 24.32% of the patients in the olanzapine group showed prolongation and shortening of the Q-Tc, respectively, while changes in the risperidone group were restricted to only prolongation of Q-Tc. Comparison of means showed a significant increment in Q-Tc by risperidone (p = 0.02). Also, comparison of proportions in the olanzapine group showed significantly more cases with shortening of Q-Tc versus its prolongation (p = 0.01). No significant alterations with respect to other variables were evident. Olanzapine and risperidone had comparable potentiality for induction of Q-Tc changes, while production of further miscellaneous alterations in ECG was more observable in the olanzapine group compared with the risperidone group. Also shortening of Q-Tc was specific to olanzapine.

Due to economic problems, sigmoid loop colostomy using glass rod may cause problems for our patients for finding glass rod and several visits. The aim of the study was to compare rod versus skin bridge colostomy. In this study, 42 cases who are candidate for colostomy were included. Cases were randomly placed in skin bridge and rod colostomy group. Independent sample t-test and Chi-square were used for comparison. SPSS version 16.0 (SPSS Inc, Chicago, IL, USA) was used for analysis. Of 42 cases, 20 were male and 22 were female. Hirschsprung's disease was the indication of colostomy in 33 cases. In nine cases, imperforate anus was the indication of colostomy. Mean time of surgery was 79.4 and 82.5 minute for the rod and skin bridge group respectively (P>0.05). Retraction was seen in 2 case of rod group, and no case of skin bridge group. Prolapse was seen in 2 (9.5%) case of rod group and 1(4.7%) case in skin bridge. There were no reports of necrosis, stenosis, and hernia in both groups. In the skin bridge group the rates of complications were lower but the groups are too small for statistical analysis. Colostomy with a skin bridge method may decrease number of revision and expenses and may be appropriate option. Sigmoid loop colostomy using skin bridge flap may be appropriate choice in developing country. Another study with more samples is recommended to better comparison of Skin Bridge versus rod colostomy.

Personality has an important role in understanding both fibromyalgia syndrome (FMS) and major depressive disorder (MDD). This study considers the question that specific personality features may characterize depressed FMS patients. To this end, 125 individuals were included in the study: 40 of them diagnosed with FMS+ MDD, 40 with MDD only and 45 healthy controls. Individual Beck Depression Inventory (BDI) and Personality Belief Questionnaire-Short Form (PBQ-SF) scores were compared between the three groups. The mean scores for each personality domain of the PBQ-SF were the highest in the MDD group and the lowest mean scores appeared in the control group. Dependent personality and obsessive-compulsive personality scores were higher in the MDD group (t = 2.510, P = 0.014 and t = 2.240, P = 0.028, respectively) in comparison with the FM+ MDD group. However, this difference disappeared when PBQ-SF scores were controlled for depression severity. Although some common personality features are evident in FMS patients, it seems that the differences identified are primarily related to depression symptom severity.

Violation of reproductive function in patients with celiac disease can manifest as delayed puberty, infertility, amenorrhea, premature menopause, spontaneous abortion, low birth weight. The aim of the study was to establish the frequency and nature of reproductive function violation in patients with CD in the Russian Federation. The study included 132 women (average age 38,5 +/- 1,17 years) with CD observed in CSRIG in the period from 2000 to 2010. Comparison group consisted 105 women (average age 38,7 +/- 1,6 years) with predominantly functional bowel disorders (irritable bowel syndrome, functional constipation, functional bloating, inert colon). Were took into account information regarding obstetric history, physical and laboratory signs of malabsorption syndrome (MS) study of antibodies to alpha-gliadin immunoglobulin (IG) A class (AGA) and tissue transglutaminase (AtTG). The average age of onset of menses was 14,3 +/- 1,4 years, and in the control group - 13,0 +/- 1,3 years (p > 0.05), half of patients with C (43.9%) had menstruation begun at age 15 years and older, while 7.6% of the women--aged 17 and older. In the comparison group menses beginning after 15 years was only at 13.3% of women. In 61.3% of patients with CD was irregular menstrual cycle while in the comparison group such violations were noted in 13.3% (p < 0.001). Prolonged periods of amenorrhea we observed in women with newly diagnosed GC 3 times more likely than the comparison group: 43.9% and 11.4% respectively (p < 0.01). They also had nearly 3 times more likely to occur spontaneous miscarriage: at 46.9% and 14.3% respectively (p < 0.01). The frequency of dead children birth was about the same: 2.3% and 1.9% respectively (p > 0.05). The frequency of reproductive disorders increased with the growth of the severity of MS. In 43% of women after 6-8 months of strict adherence to a gluten-free diet (GFD) had disappeared amenorrhea and there were regular menses. Three women of childbearing age, strictly abided the GFD and had a history of repeated spontaneous abortion during the year managed to get pregnant and give birth to healthy full-term baby. Reproductive disorders in women with celiac disease are significantly more likely than at women with functional bowel disease. One of the reasons of reproductive disorders in patients with CD can be malabsorption of necessary nutrients in the small intestine. The presence of reproductive disorders should be considered as a risk factor for celiac disease, so these women should be screened for celiac disease.

This article was designed to present evidence of the advantages of the personified approach to the treatment of the patients presenting with arterial hypertension (AH), lumbar spinal dorsopathy (LSD), chronic obstructive pulmonary disease (COPD), and duodenal ulcer (DU) at the stage of exacerbation obtained by the measurements of testing voltage at the reference point (Utest). The objective of the present study was to develop the algorithm for the determination of the sufficient number (optimal duration) of therapeutic procedures of the protracted treatment with the use of the Utest at the reference point. The study included 647 patients (439 women and 208 men at the age varying from 25 to 72 years) with grade I-II AH, DU at the stage of exacerbation, grades II and III lumbar spinal dorsopathy, grade II-III COPD. The informed written content to participate in the study was obtained from all the patients. They were divided into three groups. Those comprising group 1 were treated by standard therapy, patients of group 2 received the same treatment supplemented by dynamic electroneurostimulation (DENS) while the patients of the third group were given personified DENS in accordance with the determined sufficient number of DENS procedures. The blood pressure in the patients with AH comprising group 3 was found to decrease more significantly in comparison with those in groups 1 an 2 (by 9% and 3% respectively). The intensity of pain syndrome in the patients with lumbar spinal dorsopathy evaluated based on the visual analog scale decreased two-fold in group 3 in comparison with the 1.2 and 1.8 times decrease in groups 1 and 2 respectively. The level of pH in the stomach of patients with DU increased by 33.3% in group 3 in comparison with 12,5%, in group 1 and 21,8% in group 2. Vital capacity of the lungs in the patients of group 3 presenting with COPD and treated with the use of the personified approach was found to increase almost up to 612 ml in comparison with 477 ml in the patients given DENS in combination with standard therapy and only 219 ml in the control group. The results of the present study give evidence of the advantage of the personified treatment based on the determination of the sufficient number of the therapeutic procedures needed for the protracted treatment with the use of the Utest at the reference point. This approach can be used as a tool for the evaluation of the functional state of the patients and a method for the management of a chosen therapeutic strategy.

Endopyelotomy and laparoscopic pyeloplasty are established procedures for ureteropelvic junction obstruction (UPJO) and historically a high failure rate has been observed in poorly functioning units with UPJ obstruction. The aim of this study is to compare the results of laparoscopic pyeloplasty with endopyelotomy in poorly functioning renal units, i.e., GFR under 25 ml/min. Materials and Methods: Retrospective analysis of all the patients who underwent either laparoscopic pyeloplasty or endopyelotomy for ureteropelvic junction obstruction in poorly functioning units between January 1998 and June 2005 was done. Follow-up renal scans, done at three, six, 12 months and yearly thereafter, were studied. Success was defined as symptomatic relief and/ or improvement in function (10% over baseline) in renal scan. Results: There were 23 patients in the endopyelotomy group and 15 patients in the laparoscopic pyeloplasty group with mean age of 25.3 years (9-53) and 26 years (10-44), respectively. Mean pelvic volume was 41.2 8cc ± 9.5 and 39.1cc ± 9.85 in the endopyelotomy group and laparoscopic pyeloplasty group, respectively. Mean preoperative GFR was 17.4 ± 5.7 ml/min and 21 ± 4.5 ml/min in the endopyelotomy group and laparoscopic pyeloplasty group, respectively and mean postoperative GFR was 21 ± 3.5 ml/min and 22 ± 3.9 ml/min, respectively. Eighteen and 11 patients were symptomatic in ethe ndopyelotomy group and laparoscopic pyeloplasty group, respectively while symptomatic improvement was seen in 14 and 11 patients, respectively. Mean follow-up was 12 months in the laparoscopy group and 28 months in the endopyelotomy group. Success rate was better for laparoscopic surgery group (15/15 = 100%) than for endopyelotomy (18/23 = 78.26%). Conclusions: Though the improvement in renal function is less in patients with UPJO with poorly functioning kidneys undergoing endopyelotomy or laparoscopic pyeloplasty, laparoscopic pyeloplasty gives better results in the form of symptomatic relief; however, renal function remains stable whichever the approach chosen.

We investigated the effects of dietary intervention with canola or olive oil in comparison with commonly used refined oil in Asian Indians with nonalcoholic fatty liver disease (NAFLD). This was a 6-month intervention study including 93 males with NAFLD, matched for age and body mass index (BMI). Subjects were randomized into three groups to receive olive oil (n=30), canola oil (n=33), and commonly used soyabean/safflower oil (control; n=30) as cooking medium (not exceeding 20 g/day) along with counseling for therapeutic lifestyle changes. The BMI, fasting blood glucose (FBG) and insulin levels, lipids, homeostasis model of assessment for insulin resistance (HOMA-IR), HOMA denoting β-cell function (HOMA-βCF), and disposition index (DI) were measured at pre- and post-intervention. Data were analyzed with one-way analysis of variance (ANOVA) and Tukey's Honestly Significant Difference multiple comparison test procedures. Olive oil intervention led to a significant decrease in weight and BMI (ANOVA, P=0.01) compared with the control oil group. In a comparison of olive and canola oil, a significant decrease in fasting insulin level, HOMA-IR, HOMA-βCF, and DI (P<0.001) was observed in the olive oil group. Pre- and post-intervention analysis revealed a significant increase in high-density lipoprotein level (P=0.004) in the olive oil group and a significant decrease in FBG (P=0.03) and triglyceride (P=0.02) levels in the canola oil group. The pre- and post-intervention difference in liver span was significant only in the olive (1.14 ± 2 cm; P<0.05) and canola (0.66 ± 0.33 cm; P<0.05) oil groups. In the olive and canola oil groups, post-intervention grading of fatty liver was reduced significantly (grade I, from 73.3% to 23.3% and from 60.5% to 20%, respectively [P<0.01]; grade II, from 20% to 10% and from 33.4% to 3.3%, respectively [P<0.01]; and grade III, from 6.7% to none and from 6.1% to none, respectively). In contrast, in the control oil group no significant change was observed. Results suggest significant improvements in grading of fatty liver, liver span, measures of insulin resistance, and lipids with use of canola and olive oil compared with control oils in Asian Indians with NAFLD.

This study compared the effectiveness of hand and ultrasonic instrumentation for removing a standardized inoculum of pigmented Serratia marcescens from the root canal system of premolars in dogs. Forty-four premolars from nine beagle dogs were divided into two experimental groups of 20 and 24 teeth, respectively. The experimental teeth were inoculated with approximately 10 colony-forming units of S. marcescens. After the bacterial were allowed to colonize for 1 wk, the experimental teeth were instrumented with either hand instruments or the Cavi-Endo device. The teeth were extracted, crushed, and assayed for recoverable colony-forming units of S. marcescens. Statistical comparisons of the ratio of inoculated to recovered colony-forming untis were made. The results indicated that the difference between the positive controls and the experimental groups was significant. There was no significant difference between the two instrumentation groups.

Meeting the food needs of Africa's growing population will require innovative and appropriate technologies whose effectiveness needs to be assessed. To evaluate the impact of Solar Market Gardens (SMGs) on crops production diversity and dietary diversity in the Kalalé district of Northern Benin. In 2007, SMGs were installed in 2 villages for women's agricultural groups as a strategy for enhancing food and nutrition security. Data were collected through interviews at installation and 1 year later from all women's group households (30-35 women/group) and from a random representative sample of 30 households in each village, for both treatment and matched-pair comparison villages. Comparison of baseline and endline data indicated increases in the variety of fruits and vegetables produced and consumed by SMG women's groups compared to other groups. The proportion of SMG women's group households engaged in vegetable and fruit production significantly increased by 26% and 55%, respectively (P < .05). After controlling for baseline values, SMG women's groups were 3 times more likely to increase their fruit and vegetable consumption compared with comparison non-women's groups (P < .05). In addition, the percentage change in corn, sorghum, beans, oil, rice and fish purchased was significantly greater in the SMG women's groups compared to other groups. At endline, 57% of the women used their additional income on food, 54% on health care, and 25% on education. Solar Market Gardens have the potential to improve household nutritional status through direct consumption and increased income to make economic decisions. © The Author(s) 2016.

According to previous reports, lobectomy with bronchoplasty or angioplasty is a more feasible surgery than pneumonectomy for central-type non-small cell lung cancer. However, few studies have compared both the short- and long-term outcomes between pneumonectomy and pulmonary function-preserving surgery. From January 2004 to December 2015, 18 patients underwent pneumonectomy (Group PN) and 12 patients underwent pulmonary function-preserving surgery (group PS) at Fukushima Medical University Hospital. Clinicopathological factors were statistically compared between the two groups. The operation times in Group PN and Group PS were 285.9±27.9 and 271.3±99.2 min, respectively (p=0.613), while the amounts of intraoperative bleeding were 324.8±248.9 and 164.5±116.6 g, respectively (p=0.020). The duration of chest drainage and hospitalization after surgery in both groups were not significantly different but there was a tendency toward shorter periods of these durations in Group PS. The 5-year disease-free survival (DFS) rate in Group PN and PS was 51.4% and 74.1%, respectively, without a significant difference (p=0.298). The 5-year overall survival (OS) rate in Group PN and PS was 52.5% and 56.6%, respectively, also without a significant difference (p=0.748). The 5-year OS rate was inferior to the 5-year DFS rate in Group PS, and the 5-year OS rate was not better than the 5-year DFS rate in Group PN. The short-term results were better in Group PS than PN. However, the long-term results in both groups were similar. Other causes of death influenced OS in both groups; this result might have been affected by the surgical procedures.

To investigate the expression of receptor activator of nuclear factor kappaB ligand (RANKL) and osteoprotegerin (OPG) in periapical cyst and periapical granuloma by comparison with the expression in the normal periodontal tissue as control, and to identify their functional mechanism in the bone destruction of periapical cyst and granuloma. 20 periapical cyst tissues (cyst group), 20 periapical granuloma tissues (granuloma group), and 20 normal periodontal tissues (control group) were collected respectively. Immunohistochemical technology was performed to detect the expression of RANKL and OPG in above three groups. In cyst group, granuloma group and control group, the expression of RANKL were 75.00 +/- 7.54, 68.40 +/- 6.74 and 29.40 +/- 2.46, respectively. The expression of OPG were 38.10 +/- 7.09, 47.65 +/- 13.85 and 58.60 +/- 5.88, respectively. The differences among the three groups were statistically significant (P<0.05). RANKL and OPG in cysts group were negatively correlated (r=-0.56, P=0.01) and were not correlated with granuloma and control group (P>0.05). RANKL and OPG play roles in the bone absorption of periapical disease. In periapical disease, abnormal expression of RANKL and OPG are detected, RANKL significantly increase, OPG decrease, bone absorption accelerate and osteolytic lesion are observed. In periapical cyst, the bone absorption is more active compared with periapical granuloma.

A comparison was made of the outcomes after transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (AVR) in high-risk patients. All patients aged > 75 years that underwent a procedure for severe aortic stenosis with or without coronary revascularization at the authors' institution were included in the study; thus, 64 patients underwent TAVI and 188 underwent AVR. Patients in the TAVI group were older (mean age 84 +/- 5 versus 80 +/- 4 years; p < 0.0001) and had a higher logistic EuroSCORE (p = 0.004). Six patients (9%) died during the procedure in the TAVI group, and 23 (12%) died in the AVR group (p = 0.5). Predictors for mortality were: age (p < 0.0001), female gender (p = 0.02), and surgical valve replacement (p = 0.01). Gradients across the implanted valves at one to three months postoperatively were lower in the TAVI group (p < 0.0001). Actuarial survival at one, two and three years was 78%, 64% and 64%, respectively, for TAVI, and 83%, 78% and 75%, respectively, for AVR (p = 0.4). Age was the only predictor for late mortality (p < 0.0001). TAVI patients were older and posed a higher predicted surgical risk. Procedural mortality was lower in the TAVI group, but mid-term survival was similar to that in patients undergoing surgical AVR. Age was the only predictor for late survival. These data support the referral of high-risk patients for TAVI.

In the Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified Release Controlled Evaluation (ADVANCE) factorial trial, the combination of perindopril and indapamide reduced mortality among patients with type 2 diabetes, but intensive glucose control, targeting a glycated hemoglobin level of less than 6.5%, did not. We now report results of the 6-year post-trial follow-up. We invited surviving participants, who had previously been assigned to perindopril-indapamide or placebo and to intensive or standard glucose control (with the glucose-control comparison extending for an additional 6 months), to participate in a post-trial follow-up evaluation. The primary end points were death from any cause and major macrovascular events. The baseline characteristics were similar among the 11,140 patients who originally underwent randomization and the 8494 patients who participated in the post-trial follow-up for a median of 5.9 years (blood-pressure-lowering comparison) or 5.4 years (glucose-control comparison). Between-group differences in blood pressure and glycated hemoglobin levels during the trial were no longer evident by the first post-trial visit. The reductions in the risk of death from any cause and of death from cardiovascular causes that had been observed in the group receiving active blood-pressure-lowering treatment during the trial were attenuated but significant at the end of the post-trial follow-up; the hazard ratios were 0.91 (95% confidence interval [CI], 0.84 to 0.99; P=0.03) and 0.88 (95% CI, 0.77 to 0.99; P=0.04), respectively. No differences were observed during follow-up in the risk of death from any cause or major macrovascular events between the intensive-glucose-control group and the standard-glucose-control group; the hazard ratios were 1.00 (95% CI, 0.92 to 1.08) and 1.00 (95% CI, 0.92 to 1.08), respectively. The benefits with respect to mortality that had been observed among patients originally assigned to blood-pressure-lowering therapy were attenuated but still evident at the end of follow-up. There was no evidence that intensive glucose control during the trial led to long-term benefits with respect to mortality or macrovascular events.

This study aims to examine the personality characteristics in parricide offenders, by using the Minnesota Multiphasic Personality Inventory (MMPI) test, which is commonly used in clinical medicine. A total of 73 parricide offenders with schizophrenia who were admitted to National Forensic Hospital in Gongju city between September 2014 and February 2015, and 104 comparison schizophrenia patients who had been admitted to Dankook University Hospital in Cheonan city the same hospital, completed the Korean version of the MMPI. The parricide offender group showed significantly higher on L, F, Hs, Hy and Pd than the comparison group. The result of the regression analysis indicated that Pd and Si significantly increased the odd ratio of the sexual offender group by 2.77 times and 0.32 times, respectively (p=0.029 and p=0.023). The offenders of parricide may have developed the following characteristics: hypochondriasis, hysteria and psychopathic deviate. These results suggested that the psychopatholgy in the offenders of parricide might be different, compared to the control group.

Published and unpublished data from nine studies on juvenile sexual offender treatment effectiveness were summarized by meta-analysis (N=2986, 2604 known male). Recidivism rates for sexual, non-sexual violent, non-sexual non-violent crimes, and unspecified non-sexual were as follows: 12.53%, 24.73%, 28.51%, and 20.40%, respectively, based on an average 59-month follow-up period. Four included studies contained a control group (n=2288) and five studies included a comparison treatment group (n=698). An average weighted effect size of 0.43 (CI=0.33-0.55) was obtained, indicating a statistically significant effect of treatment on sexual recidivism. However, individual study characteristics (e.g., handling of dropouts and non-equivalent follow-up periods between treatment groups) suggest that results should be interpreted with caution. A comparison of odds ratios by quality of study design indicated that higher quality designs yielded better effect sizes, though the difference between groups was not significant.

This study evaluated levels for mRNA expression of 7 cytokines in ocular toxoplasmosis. Peripheral blood mononuclear cells (PBMC) of patients with ocular toxoplasmosis (OT Group, n = 23) and chronic toxoplasmosis individuals (CHR Group, n = 9) were isolated and stimulated in vitro with T. gondii antigen. Negative controls (NC) were constituted of 7 PBMC samples from individuals seronegative for toxoplasmosis. mRNA expression for cytokines was determined by qPCR. Results showed a significant increase in mRNA levels from antigen stimulated PBMCs derived from OT Group for expressing IL-6 (at P < .005 and P < .0005 for CHR and NC groups, respectively), IL-10 (at P < .0005 and P < .005 for CHR and NC groups, respectively) and TGF-β (at P < .005) for NC group. mRNA levels for TNF-α and IL-12 were also upregulated in patients with OT compared to CHR and NC individuals, although without statistical significance. Additionally, mRNA levels for IL-27 and IFN-γ in PBMC of patients with OT were upregulated in comparison with NC individuals. Differences between OT and NC groups were statistically significant at P < .05 and P < .0005, respectively. © 2017 John Wiley & Sons Ltd.

Adhesion molecules play an important role in the development and progression of coronary atherosclerosis. The aim of this study was comparing the effect of Cratagol herbal tablet, aerobic exercise and their combination on the serum levels of Intercellular adhesion molecule (ICAM)-1 and E-Selectin in patients with stable angina pectoris. Eighty stable angina pectoris patients aged between 45 and 65 years, were randomly divided into four groups including three experimental groups and one control group: aerobic exercise (E), Crataegus oxyacantha extract (S), aerobic exercise and Crataegus oxyacantha extract (S+E), and control (C). Blood sampling was taken 24 h before and after 12 weeks of aerobic exercise and Crataegus oxyacantha extract consumption. The results of serum levels of ICAM-1 and E-selectin were compared. Intergroup comparison of the data revealed a significant reduction (P <0.01) in serum levels of ICAM-1 and E-selectin in experimental groups. Analysis of data showed that the serum levels of ICAM-1 had significant difference when group S+E was compared with groups S and C, but not group E (P = 0.021, P = 0.000 and P = 0.068, respectively). Also the difference between the levels of E-selectin was significant comparing S+E and S but not E with group C (P = 0.021, P = 0.000 and P = 0.052, respectively). Twelve weeks effects of aerobic exercise and Crataegus oxyacantha extract consuming is an effective complementary strategy to significantly lower the risk of atherosclerosis and heart problems.

ABSTRACT Introduction: Maintenance of good oral hygiene is important for patients undergoing fixed orthodontic treatment. Aim: The aim of this study was to evaluate the effectiveness of a manual orthodontic toothbrush, powered toothbrush with oscillating head and sonic toothbrush in controlling plaque, gingivitis and interdental bleeding in patients undergoing fixed orthodontic treatment, and to compare their relative efficacy. Materials and methods: Sixty subjects, who were to receive orthodontic treatment with both upper and lower fixed appliances, were randomly divided into three study groups, with 20 patients in each group. Groups I to III were given manual orthodontic, powered and sonic toothbrushes, respectively. Plaque index (PI), gingival index (GI) and interdental bleeding index were scored to assess the level of plaque accumulation, gingival health and interdental bleeding at baseline; 4 and 8 weeks recall visits after fixed appliance bonding. Paired t-tests and one-way analysis of variance (ANOVA) tests were used for intragroup and intergroup comparisons. The level of statistical significance was set at p < 0.05. Results: This study showed that a significant reduction in all the three indices scores was found from baseline to 4 and 8 weeks in group III. On intergroup comparison, no statistically significant differences were detected between the three groups for any of the parameters assessed. Conclusion: On intragroup comparison, sonic brushes performed superiorly in reducing gingivitis, plaque and interdental bleeding as compared to the manual orthodontic and powered brushes. On intergroup comparison, the relative comparative effectiveness was found to be similar for all the three brushes. How to cite this article: Sharma R, Trehan M, Sharma S, Jharwal V, Rathore N.

In hypercholesterolemia increased lipid and lipoprotein peroxidation occurs. The renin-angiotensin system plays an important role in atherogenesis. Angiotensin II induces smooth muscle cells proliferation and stimulates oxidation of LDL particles and foam cell accumulation. Inhibition of ang II production leads to decrease in lipid peroxide production. The aim of this study was to assess the lipid peroxidation expressed as concentration of thiobarbituric acid reactive species (TBARS) in sera and aorta homogenates after administration of two doses of angiotensin-converting enzyme (ACE) inhibitors (captopril, enalapril and quinapril) in diet-induced hypercholesterolemia in rabbits. Sixty-four New Zealand rabbits were used. Animals were fed with standard fodder, special diet (1% cholesterol content) or special diet + tested ACEI. Two doses of ACE inhibitors were used: i), equivalent to applied to humans, ii), dose 10 times higher. The animals were divided into 8 groups: control, standard fodder; B, special diet; C1, C2, special diet + captopril in doses 2.5 and 25 mg/kg/24 h, respectively; E1, E2, special diet + enalapril in doses 0.75 and 7.5 mg/kg/24 h, respectively; Q1 and Q2, special diet + quinapril in doses 0.75 and 7.5 mg/kg per day, respectively. In cholesterol-fed rabbits and in groups receiving lower doses of tested ACE inhibitors, the serum TBARS concentration at 6 months was significantly higher in comparison to the control. The higher doses of enalapril, quinapril and captopril, prevented the cholesterol-induced rise in TBARS concentration. Lower dose of captopril attenuated the rise in TBARS concentration, it was significantly lower in comparison to group B, but higher than in the control group. In animals from groups B, E1, C1, Q1 TBARS concentration in aortae was significantly higher as compared to control group. Both doses of captopril and higher doses of enalapril and quinapril inhibited the rise of lipid peroxides concentration induced by cholesterol-rich diet.

We compared placental-derived and amniotic fluid-derived mesenchymal stem cells (pMSCs and afMSCs, respectively) in transamniotic stem cell therapy (TRASCET) for experimental spina bifida. Pregnant dams (n=29) exposed to retinoic acid for the induction of fetal spina bifida were divided into four groups. Three groups received volume-matched intraamniotic injections of either saline (n=38 fetuses) or a suspension of 2×10(6) cells/mL of syngeneic, labeled afMSCs (n=73) or pMSCs (n=115) on gestational day 17 (term=21-22days). Untreated fetuses served as controls. Animals were killed before term. Statistical comparisons were by Fisher's exact test (p<0.05). Survival was similar across treatment groups (p=0.08). In fetuses with isolated spina bifida (n=100), there were higher percentages of defect coverage (either partial or complete) in both afMSC and pMSC groups compared with saline and untreated groups (p<0.001-0.03 in pairwise comparisons). There were no differences in coverage rates between afMSC and pMSC groups (p=0.94) or between saline and untreated groups (p=0.98). Both pMSC and afMSC can induce comparable rates of coverage of experimental spina bifida after concentrated intraamniotic injection in the rodent model. This broadens the options for timing and cell source for TRASCET as a potential alternative in the prenatal management of spina bifida. Copyright © 2016 Elsevier Inc. All rights reserved.

Studies on the therapeutic efficacy of proton pump inhibitors (PPIs) in patients with gastroesophageal reflux disease (GERD) have been recently published. In most of these studies, comparison of only two PPIs have been made. There are few studies on the comparison of four or more PPIs. We aimed to compare the acid inhibitory effects of esomeprazole 40 mg, rabeprazole 20 mg, lansoprazole 30 mg, and pantoprazole 40 mg on days 1 and 5 of treatment in patients with GERD, who were extensive metabolizers in regard to the CYP2C19 genotype. Helicobacter pylori-negative with typical symptoms of GERD patients were randomly divided into four treatment groups. Efficacy analysis on days 1 and 5 were performed on the four groups which comprised 10 (esomeprazole), 11 (rabeprazole), 10 (lansoprazole), and 10 (pantoprazole) patients. On day 1 of PPI treatment, the mean percentage of time with intragastric Ph>4 were 54%, 58%, 60%, and 35% for the groups, respectively, and on day 5, these values were 67%, 60%, 68%, and 59%, respectively. Esomeprazole, rabeprazole, and lansoprazole were found to be superior to pantoprazole on the first day of treatment. Pantoprazole is a less potent proton pump inhibitor than the other PPIs tested on the first day of treatment. When the time needed to raise the intragatric pH to over 4 was evaluated, esomeprazole was found to have the most rapid action, followed by lansoprazole and rabeprazole.

Elucidating differences in social-behavioral profiles of children with comorbid presentations, utilizing caregiver as well as teacher reports, will refine our understanding of how contextual symptoms vary across anxiety-related disorders. In our pediatric anxiety clinic, the most frequent diagnoses and comorbidities were mixed anxiety (MA; ≥ 1 anxiety disorder; N = 155), anxiety with comorbid attention-deficit hyperactivity disorder (MA/ADHD, N = 47) and selective mutism (SM, N = 48). Behavioral measures (CPRS, CTRS) were analyzed using multiple one-way multivariate analyses of covariance tests. Differences between the three diagnostic groups were examined using completed parent and teacher reports (N = 135, 46, and 48 for MA, MA/ADHD, and SM groups, respectively). Comparisons across the MA, MA/ADHD, and SM groups indicate a significant multivariate main effect of group for caregiver and teacher responses (P < 0.01). Caregivers reported that children with SM are similar in profile to those with MA, and both groups were significantly different from the MA/ADHD group. Teachers reported that children with SM had more problems with social behaviors than with the MA or MA/ADHD groups. Further comparison indicates a significant main effect of group (P < 0.001), such that children with SM have the greatest differences in behavior observed by teachers versus caregivers. Clinical profiles between MA/ADHD, MA, and SM groups varied, illustrating the importance of multi-rater assessment scales to capture subtle distinctions and to inform treatment planning given that comorbidities occur frequently in children who present with anxiety. © 2013 Wiley Periodicals, Inc.

This research apply Dingkun Dan to treat patients with dysmenorrhea of cold stagnation and blood stasis syndrome. This study observed its effectiveness and safety of the treatment of the disease and its influence on the serum prostaglandin F2α, endothefin, pulsatility index and resistant index of uterine artery blood, to explore the possible mechanism of effect of Dingkun Dan in the treatment of dysmenorrhea and provide scientific basis for clinical application. The 75 patients with dysmenorrhea of cold stagnation and blood stasis who met the inclusion criteria, were divided into treatment group (n=37) and control group (n=38) by using random number remainder grouping method. In the treatment group patients were treated with Dingkun Dan, the other group were given Fuke Zaizao Jiaonang. Two groups have same time to take the medicine, three days prior to the menstruation for ten days. Medication for three menstrual cycles was seen as a course of treatment. To observe and compare the two groups of patients before and after treatment VAS score, syndrome integral, serum levels of prostaglandin F2α and endothelin, pulsation index and resistance index of uterine artery blood flow and related safety index changes. Finally makes statistical analysis. It has been identified that, Treatment group and control group can reduce pain symptom of dysmenorrhea patients and improve the syndromes scores, compare with control group, effect of the treatment group is more significant(P<0.01). VAS pain curative effect: the treatment group and control group total effective rate respectively were, 97.22%, 69.44%, markedly effective rate were 83.33%, 30.56%, comparison between two groups, treatment group is better than that of control group(P＜0.01). Syndromes curative effect: the treatment group and control group total effective rate respectively were 97.22%, 94.44%, markedly effective rate was 66.67%, 2.78%, respectively. The comparison between two groups, the total effective rate has no obvious difference, but markedly effective rate of treatment group is better than that of control group(P＜0.01). The treatment group can significantly reduce the patients' serum level of prostaglandin F2α(P<0.01), but no obvious difference was found in the control group before and after treatment. Both groups can significantly reduce the serum level of endothelin(P<0.01), comparison between two groups, the treatment group is more significant(P<0.01).Both treatment group and control group were significantly lower left and right pulsation index and resistance index of uterus artery blood flow(P<0.01). Between groups to compare the effect, the treatment group is more significant(P<0.01). Both treatment group and control group in the security check before and after treatment found no significant anomalies. Dingkun Dan in treating dysmenorrhea with cold stagnation and blood stasis syndrome seems to have remarkable clinical curative effect and safety, which may be achieved by significantly reducing the serum level of prostaglandin F2αand endothefin of the patients, and reducing the pulsation index and resistance index of uterine artery blood flow of the patients, to improve uterine artery condition of blood, and correcting local tissue ischemia to relieve pain.

Recent advances in next-generation sequencing (NGS) have provided new methods for preimplantation genetic screening (PGS) of human embryos from in vitro fertilization (IVF) cycles. However, there is still limited information about clinical applications of NGS in IVF and PGS (IVF-PGS) treatments. The present study aimed to investigate the effects of NGS screening on clinical pregnancy and implantation outcomes for PGS patients in comparison to array comparative genomic hybridization (aCGH) screening. This study was performed in two phases. Phase I study evaluated the accuracy of NGS for aneuploidy screening in comparison to aCGH. Whole-genome amplification (WGA) products (n = 164) derived from previous IVF-PGS cycles (n = 38) were retrospectively analyzed with NGS. The NGS results were then compared with those of aCGH. Phase II study further compared clinical pregnancy and implantation outcomes between NGS and aCGH for IVF-PGS patients. A total of 172 patients at mean age 35.2 ± 3.5 years were randomized into two groups: 1) NGS (Group A): patients (n = 86) had embryos screened with NGS and 2) aCGH (Group B): patients (n = 86) had embryos screened with aCGH. For both groups, blastocysts were vitrified after trophectoderm biopsy. One to two euploid blastocysts were thawed and transferred to individual patients primarily based on the PGS results. Ongoing pregnancy and implantation rates were compared between the two study groups. NGS detected all types of aneuploidies of human blastocysts accurately and provided a 100 % 24-chromosome diagnosis consistency with the highly validated aCGH method. Moreover, NGS screening identified euploid blastocysts for transfer and resulted in similarly high ongoing pregnancy rates for PGS patients compared to aCGH screening (74.7 % vs. 69.2 %, respectively, p >0.05). The observed implantation rates were also comparable between the NGS and aCGH groups (70.5 % vs. 66.2 %, respectively, p >0.05). While NGS screening has been recently introduced to assist IVF patients, this is the first randomized clinical study on the efficiency of NGS for preimplantation genetic screening in comparison to aCGH. With the observed high accuracy of 24-chromosome diagnosis and the resulting high ongoing pregnancy and implantation rates, NGS has demonstrated an efficient, robust high-throughput technology for PGS.

Knowledge of obstetric danger signs and adequate birth preparedness (BP) are critical for improving maternal services utilization. This study assessed the effect of a participatory multi-sectoral maternal and newborn intervention on BP and knowledge of obstetric danger signs among women in Eastern Uganda. The Maternal and Neonatal Implementation for Equitable Systems (MANIFEST) study was implemented in three districts from 2013 to 2015 using a quasi-experimental pre-post comparison design. Data were collected from women who delivered in the last 12 months. Difference-in-differences (DiD) and generalized linear modelling analysis were used to assess the effect of the intervention on BP practices and knowledge of obstetric danger signs. The overall BP practices increased after the intervention (DiD = 5, p < 0.05). The increase was significant in both intervention and comparison areas (7-39% vs. 7-36%, respectively), with a slightly higher increase in the intervention area. Individual savings, group savings, and identification of a transporter increased in both intervention and comparison area (7-69% vs. 10-64%, 0-11% vs. 0-5%, and 9-14% vs. 9-13%, respectively). The intervention significantly increased the knowledge of at least three obstetric danger signs (DiD = 31%) and knowledge of at least two newborn danger signs (DiD = 21%). Having knowledge of at least three BP components and attending community dialogue meetings increased the odds of BP practices and obstetric danger signs' knowledge, respectively. Village health teams' home visits, intervention area residence, and being in the 25+ age group increased the odds of both BP practices and obstetric danger signs' knowledge. The intervention resulted in a modest increase in BP practices and knowledge of obstetric danger signs. Multiple strategies targeting women, in particular the adolescent group, are needed to promote behavior change for improved BP and knowledge of obstetric danger signs.

The optimal method for pancreatic stump closure to prevent postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP), remains controversial though DP is still the only curative treatment for pancreatic cancer and other malignancies located on pancreatic body or tail. A total of 44 patients who consecutively underwent open DP were retrospectively analyzed, dividing them into two groups: group H (hand-sewn; n=24) and group S (stapler closure; n=20). POPFs were encountered in 5 (21%) and 11 (55%) patients in groups H and S, respectively (p=0.02). POPFs of Clavien-Dindo grade IIIa or above were observed in two (8%) and seven (35%) patients in groups H and S, respectively (p=0.03). When indicating stapler closure, caution should be exercised for pancreatic consistency and thickness, device and cartridge type, and pancreatic duct ligation to more effectively control POPF rates.

An open 10-day study of treatment effect of cereton in comparison to piracetam has been conducted. Cereton was used in 40 patients (main group) in dosage 1000 mg, piracetam - in 20 patients (control group) in dosage 2000 mg. Both drugs were used intravenous in drops in 200 ml of physiologic saline along with antiparkinsonian medications. Patient's state was assessed with a battery of psychometric scales and neuropsychological tests as well as with instruments for measuring intensity of parkinsonian symptoms, side-effects and quality of life. Marked and moderate improvement of cognitive functions was found in patients of the main group compared to the control one (40% and 25%, respectively, p<0,05). Deterioration of cognitive functions was seen less often in the main group than in the control group (5% and 15%, respectively, p<0,05). Cereton was well-tolerated by patients. Side effects (brief and short-term) were found only in 6 (15%) patients.

The present study aimed to investigate the need for and utility of the Psychopathic Personality Inventory-Revised (PPI-R) Deviant Responding (DR) and Virtuous Responding (VR) validity scales in identifying overreporting and underreporting, respectively. Since the PPI-R was published, there has not been an independent peer-reviewed examination of these scales. Participants were 384 undergraduate individuals asked to respond to the PPI-R under standard, underreporting, or overreporting instructions. A comparison group consisting of 200 forensic psychiatric patients was also used for the overreporting analyses. Effects of response bias on mean elevations on the PPI-R substantive scales were examined along with the effects on the PPI-R total, factor, and content scales' correlations with other relevant extratest measures of psychopathy. Mean elevations differed significantly, and correlations with extratest measures of psychopathy were significantly lower. Substantial decrement in psychometric validity of PPI-R scores was observed in the simulation conditions. In addition, the utility of the PPI-R validity scales in differentiating between groups was also determined. Both the VR and DR scales showed utility in differentiating between their respective dissimulation condition and the comparison groups, with acceptable rates of sensitivity and specificity.

Few studies have examined the possible cardiometabolic consequences of World Trade Center-related exposures on children who lived and/or attended school near the disaster site. Our objective was to compare cardiometabolic profiles of participants in the World Trade Center Health Registry (WTCHR) with a matched comparison group. We evaluated WTCHR enrollees who resided in New York City and were born between September 11, 1993 and September 10, 2001, and a matched comparison group. We assessed exposure to dust cloud, home dust, as well as traumatic exposure, and associations with blood pressure, arterial wall stiffness, body mass index (BMI), total cholesterol, triglycerides, HDL, and LDL. A total of 402 participants completed the study, 222 in the comparison group and 180 in the WTCHR group. In multivariable regression analysis, after adjusting for relevant confounders we detected a weak association between participation in the WTCHR group and lower BMI (-1.12kg/m 2 , 95% CI -2.11, -0.12; p = 0.03), which became non-significant after adjusting for multiple comparisons. With respect to traumatic and psychosocial exposures, the only association that persisted in our multivariable model, below our predefined level of significance, was between post-traumatic stress disorder and higher BMI (2.06kg/m2, 95% CI 0.37, 3.74; p = 0.02). Our findings do not support an association between self-reported exposures to the WTC disaster and adverse cardiometabolic profile. However, further longitudinal studies may better inform the full extent of WTC-related conditions associated with exposure to the disaster. Copyright © 2017 Elsevier Inc. All rights reserved.

Hepatic vein pressure gradient (HVPG) is the gold standard for diagnosing clinically significant portal hypertension (CSPH). The aim of this study was to investigate-in comparison to HVPG-the ability to diagnose CSPH by liver and spleen stiffness measurements obtained by acoustic radiation force impulse (ARFI) imaging. A total of 78 patients (mean age: 53 ± 13 years, 62 % male) with chronic liver disease were enrolled in this study. Each patient received liver (LSM) and spleen (SSM) stiffness measurements by ARFI, an HVPG measurement and a transjugular liver biopsy on the same day. Patients were classified according to their HVPG into three different groups: HVPG < 10 mmHg, HVPG ≥ 10-< 12 mmHg and HVPG ≥ 12 mmHg. LSM, SSM were significantly higher in patients with HVPG ≥ 10 - < 12 in comparison to HVPG < 10 mmHg (p < 0.001 and p < 0.001, respectively), and in patients with HVPG ≥ 12 mmHg in comparison to ≥ 10 - < 12 mmHg (p < 0.001 and p < 0.001, respectively). LSM and SSM were able to diagnose HVPG ≥ 10 mmHg and HVPG ≥ 12 mmHg with high diagnostic performance (AUC LSM: 0.93 and 0.87, respectively; AUC SSM: 0.97 and 0.95, respectively). The AUC of SSM in predicting esophageal varices (EVs) plus HVPG ≥ 10 mmHg and EVs plus HVPG ≥ 12 mmHg were higher compared to LSM in both groups of patients (SSM: 0.90 and 0.93 vs. LSM: 0.84 and 0.88, respectively). No significant difference between both AUCs was detected in the different HVPG groups. In the multivariate -analysis SSM remained a factor predicting HVPG (HVPG > 10 mmHg p = 0.007; HVPG ≥ 12 mmHg p = 0.003). LSM and SSM by ARFI are noninvasive diagnostic tools that may help in diagnosing CSPH. LSM and SSM could be used as a guiding noninvasive screening tool in patients with esophageal varices requiring endoscopic evaluation. © Georg Thieme Verlag KG Stuttgart · New York.

Multiple-arm randomized trials can be more complex in their design, data analysis, and result reporting than two-arm trials. We conducted a systematic review to assess the reporting of analyses in reports of randomized controlled trials (RCTs) with multiple arms. The literature in the MEDLINE database was searched for reports of RCTs with multiple arms published in 2009 in the core clinical journals. Two reviewers extracted data using a standardized extraction form. In total, 298 reports were identified. Descriptions of the baseline characteristics and outcomes per group were missing in 45 reports (15.1%) and 48 reports (16.1%), respectively. More than half of the articles (n = 171, 57.4%) reported that a planned global test comparison was used (that is, assessment of the global differences between all groups), but 67 (39.2%) of these 171 articles did not report details of the planned analysis. Of the 116 articles reporting a global comparison test, 12 (10.3%) did not report the analysis as planned. In all, 60% of publications (n = 180) described planned pairwise test comparisons (that is, assessment of the difference between two groups), but 20 of these 180 articles (11.1%) did not report the pairwise test comparisons. Of the 204 articles reporting pairwise test comparisons, the comparisons were not planned for 44 (21.6%) of them. Less than half the reports (n = 137; 46%) provided baseline and outcome data per arm and reported the analysis as planned. Our findings highlight discrepancies between the planning and reporting of analyses in reports of multiple-arm trials.

Objective: To evaluate the role of nondismembered laparoscopic pyeloplasty and percutaneous endopyelotomy for ureteropelvic junction obstruction (UPJO) with low volume renal pelvis. Material and Methods: Retrospective acquired data of 34 patients of laparoscopic nondismembered pyeloplasty was compared with 26 patients of UPJO with pelvic volume less than 50 ml undergoing antegrade endopyelotomy and analyzed for clinical parameters, operative outcomes and success of procedures. All patients were followed up clinically and with diuretic renogram at regular intervals. Results: Mean age, renal pelvic volume and preoperative glomerular filtration rate (GFR) was 25 years, 43.6 ml and 42.5 ml/min, respectively in endopyelotomy group and 21 years, 34.4 ml and 39.9 ml/min, respectively in laparoscopic pyeloplasty group. Mean operative time, postoperative analgesic requirement and mean hospital stay was 100min, 250 mg and 4 days, respectively in endopyelotomy group and 210 min, 300 mg and 4 days, respectively in laparoscopic pyeloplasty group. Only operative time was significantly different between two groups (P < 0.05). Mean follow-up was 36 and 39 months and success rates were 91.2% and 88.8% in laparoscopy and endopyelotomy group, respectively (P < 0.05). No significant complication was seen in endopyelotomy group while two patients had hematuria (one requiring blood transfusion) and three had increased drain output for more than 3 days in laparoscopy group. Conclusion: Percutaneous endopyelotomy is associated with significantly less operative time and postoperative complication rate and provides equivalent success in comparison to nondismembered laparoscopic pyeloplasty in patients with UPJO and low volume pelvis. It can be a preferred minimally invasive treatment modality for such patients. PMID:19468432

Effect of a family focused active play intervention on sedentary time and physical activity in preschool children

2012-01-01

Background Early childhood provides a window of opportunity for the promotion of physical activity. Given the limited effectiveness of interventions to date, new approaches are needed. Socio-ecological models suggest that involving parents as intervention targets may be effective in fostering healthier lifestyles in children. This study describes the effectiveness of a family-focused ‘Active Play’ intervention in decreasing sedentary time and increasing total physical activity in preschool children. Method Seventy-seven families were recruited from 8 randomly selected SureStart children’s centres in the North West of England. Centres were randomly assigned to either an intervention (n = 4) or a comparison group (n = 4). Parents and children in the intervention group received a 10-week active play programme delivered by trained active play professionals; this included an activity and educational component. Families in the comparison group were asked to maintain their usual routine. Each participating parent and child wore a uni-axial accelerometer for 7 days at baseline and post-test. Week and weekend day sedentary time and total physical activity adjusted for child- and home- level covariates were analysed using multilevel analyses. Results Significant intervention effects were observed for sedentary time and physical activity for both week and weekend days. Children in the intervention group engaged in 1.5% and 4.3% less sedentary time during week and weekend days, respectively and 4.5% and 13.1% more physical activity during week and weekend days, respectively than children in the comparison group. Parent’s participation in sport and their physical activity levels, child’s sex, availability of media in the home and attendance at organised activities were significant predictors of sedentary time and physical activity in this age group. Conclusion A 10-week family focused active play intervention produced positive changes in sedentary time and total physical activity levels in preschool children. Specific covariates were identified as having a significant effect on the outcome measures. Moreover, children whose parents were active engaged in less sedentary time and more physical activity suggesting that parent’s activity habits are mediators of physical activity engagement in this age group.

Encouraging results from a small sample of patients with myelodysplastic syndrome (MDS) undergoing haploidentical donor (HID) hematopoietic stem cell transplantation (HSCT) must be extended. Furthermore, an algorithm derived from a comparison of the outcomes of HID and identical-sibling donor (ISD) HSCT must be established. Therefore, the outcomes of 454 MDS patients who underwent HSCT from HIDs (n=226) or ISDs (n=228) between 2003 and 2013 that were reported to the Chinese Bone Marrow Transplantation Registry were analyzed. Among the 3/6 HID (n=136), 4-5/6 HID (n=90) and ISD patient groups, the 4-year adjusted cumulative incidences of non-relapse mortality were 34, 29 and 16%, respectively (overall P=0.004), and of relapse were 6, 7 and 10%, respectively (overall P=0.36). The 4-year adjusted probabilities of overall survival were 58, 63 and 73%, respectively (overall P=0.07), and of relapse-free-survival were 58, 63 and 71%, respectively (overall P=0.14); pairwise comparison showed that the difference was only statistically significant in the 3/6 HID vs ISD pair. The data suggest that ISDs remain the best donor source for MDS patients while HIDs (perhaps 4-5/6 HID in particular) could be a valid alternative when an ISD is not available; human leukocyte antigen disparity had no effect on survival among the HID patients.

The present study was designed to compare the effects of nano-selenium and of sodium selenite on the chemotactic and respiratory burst activities of neutrophils in sheep. Fifteen sheep were randomly divided into three groups. Groups 1 and 2 received selenium nanoparticles (1 mg/kg) or sodium selenite (1 mg/kg) orally, respectively, for ten consecutive days, and the third group was considered as the control. To determine the chemotactic and respiratory burst activities of the neutrophils, the leading front assay and the NBT test were used on heparinized blood samples that were collected at different intervals (days 0, 10th, 20th, and 30th). The results obtained showed that the chemotactic activities in groups 1 and 2 increased significantly on the 10th, 20th, and 30th day, compared to day 0, and on the 20th day in comparison with the 10th day, while in group 2, there was a significant decrease on the 30th day compared to the 20th day. The chemotactic activities in group 1 were significantly higher than in group 2 on the 10th day and in the control group on the 10th, 20th, and 30th day, but the chemotactic activities in group 2 were significantly higher than those in the control group only on the 20th day. On the 30th day into the experiment, the respiratory bursts in groups 1 and 2 were significantly stronger in comparison with those at day 0. Overall, nano-selenium increased the chemotactic and respiratory burst activities more significantly than sodium selenite, which is suggestive of a stronger stimulatory effect of the Se nanoparticles on intracellular activities.

The effects of cefodizime and cefuroxime on neutrophil phagocytosis and reactive oxygen production in 54 patients undergoing elective coronary artery bypass grafting were studied. Both drugs were administered twice at a dosage of 40 mg/kg of body weight (pre- and intraoperative). Phagocytic capacity was assessed by measuring the uptake of fluorescein isothiocyanate-labeled Escherichia coli and Staphylococcus aureus by flow cytometry. Reactive oxygen generation after phagocytosis was estimated by determining the amount of dihydrorhodamine 123 converted to rhodamine 123 intracellularly. In both groups the mean phagocytic ability for E. coli and S. aureus decreased during surgery (-21 and -8%, respectively, for the cefodizime group and -39 and -38%, respectively, for the cefuroxime group; P < 0.05 for all). In the cefodizime group a normalization of mean E. coli and S. aureus neutrophil phagocytosis was seen on day 5 (+9 and -4% compared to preoperative values; P > 0.35 for both), whereas in cefuroxime-treated patients phagocytic ability remained depressed (-37 and -31%; P < 0.04 for both). In both groups mean neutrophil reactive oxygen intermediate (ROI) production after E. coli and S. aureus phagocytosis increased during cardiopulmonary bypass (+44 and +83%, respectively, in the cefodizime group and +58 and +73%, respectively, in the cefuroxime group; P < 0.05 for all). One day after surgery E. coli- and S. aureus-driven neutrophil ROI production was not different from the preoperative values (-2 and +12%, respectively, for the cefodizime group and +7 and +15%, respectively, for the cefuroxime group; P > 0.15 for all). Postoperative serum levels of the C-reactive protein on days 2 and 7 were lower in cefodizime-treated patients (19 +/- 6 and 4 +/- 2 mg/liter versus 23 +/- 6 and 11 +/- 5 mg/liter; P < 0.05 for both). In addition to cefodizime's antimicrobial activity during perioperative prophylaxis, its use in coronary artery bypass grafting can prevent procedure-related prolonged postoperative neutrophil phagocytosis impairment.

Little is known about the role of antioxidant activity in the pathogenesis of stroke-associated neuronal damage and impairment following a stroke. Increased free radical formation together with reduced antioxidant defense may increase neuronal injury. A low concentration of antioxidants such as alpha-tocopherol may influence the development of post-stroke dementia. The aim of this study was to evaluate the level of alpha-tocopherol and susceptibility of LDL to oxidation in a group of patients with dementia in comparison to controls. In a group of 68 patients with dementia, according to DSM-IV criteria, 42 with vascular dementia (VaD), 26 with Alzheimer type of dementia (AD) and 46 age-matched persons, with no signs of cognitive disorders (control group), we measured lipids, alpha-tocopherol and the kinetics of LDL oxidation. The levels of triglycerides (TG) and low-density lipoprotein (LDL) were significantly lower in patients with VaD in comparison to AD patients, but the atherogenic index was similar in both groups. alpha-Tocopherol was significantly lower in patients with VaD in comparison to patients with AD and controls: 9.9, 12.6 and 12.6 ng/ml, respectively, p<0.0001. Susceptibility of LDL to oxidation, measured by duration of lag phase did not reveal statistically significant differences between the groups. In patients with VaD, low levels of plasma alpha-tocopherol were observed, which indicate a reduced antioxidant defense in these subjects.

The search for traits that make alien species invasive has mostly concentrated on comparing successful invaders and different comparison groups with respect to average trait values. By contrast, little attention has been paid to trait variability among invaders. Here, we combine an analysis of trait differences between invasive and non-invasive species with a comparison of multidimensional trait variability within these two species groups. We collected data on biological and distributional traits for 1402 species of the native, non-woody vascular plant flora of Austria. We then compared the subsets of species recorded and not recorded as invasive aliens anywhere in the world, respectively, first, with respect to the sampled traits using univariate and multiple regression models; and, second, with respect to their multidimensional trait diversity by calculating functional richness and dispersion metrics. Attributes related to competitiveness (strategy type, nitrogen indicator value), habitat use (agricultural and ruderal habitats, occurrence under the montane belt), and propagule pressure (frequency) were most closely associated with invasiveness. However, even the best multiple model, including interactions, only explained a moderate fraction of the differences in invasive success. In addition, multidimensional variability in trait space was even larger among invasive than among non-invasive species. This pronounced variability suggests that invasive success has a considerable idiosyncratic component and is probably highly context specific. We conclude that basing risk assessment protocols on species trait profiles will probably face hardly reducible uncertainties. PMID:27187616

The Oral Rapamycin in ARgentina (ORAR) III trial is a randomized study comparing a strategy of oral rapamycin (OR) plus bare-metal stent (BMS) versus a strategy of drug-eluting stents (DES) in patients with de novo coronary lesions. The purpose of this study was to assess the 3 years cost-effectiveness outcome of each strategy. OR after BMS has been associated with reduction of target vessel revascularization (TVR) although its value in long-term efficacy in comparison with DES is unknown. In three hospitals in Buenos Aires, Argentina, 200 patients were randomized to OR plus BMS (n = 100) or DES (n = 100). Primary objectives were costs and effectiveness. Cost analysis included in-hospital and follow-up costs. Safety was defined as the composite of death, myocardial infarction (MI), and stroke. Efficacy was defined as TVR. Baseline characteristics between groups were similar. The 3-year follow-up rate was 99%. Cardiac mortality was 2% and 5% in OR group and DES group, respectively (P = 0.44). The composite of death, MI and stroke rate was 11% in OR group and 20% in DES group (P = 0.078). TVR rate was 14.5% in OR group and 17.6% in DES group (P = 0.50), respectively. Three year cumulative costs were significantly lower in the OR arm as compared to the DES arm (P = 0.0001) and DES strategy did not result cost-effective according to the non-inferiority test. At 3 years follow-up, there were no differences in effectiveness between the two strategies, and DES strategy was not more cost-effective as compared to OR plus BMS.

This study examined birth outcomes in five towns in Shoshone County, Idaho, where residents were exposed to high levels of lead in air emissions during a 6-month period after a fire had damaged the main baghouse (pollution-control device) of a local lead smelter plant in September 1973. We studied birth certificate data of 169,878 live singleton infants born to mothers who resided in Idaho at the time of delivery. The outcomes evaluated were preterm infants, small-for-gestational-age (SGA) infants, low birthweight among term infants (TLBW), and mean birthweight among term infants (TMBW). The study compared births in the five towns in Shoshone County (exposed group) to births in the rest of Idaho during three exposure periods: "pre-fire," January 1, 1970-August 31, 1973; "high exposure," September 1, 1973-December 31, 1974; and "post-fire," January 1, 1975-December 31, 1981. During the high-exposure period, the exposed group had an increased prevalence of TLBW (OR=2.4; 90% CI: 1.6-3.6) and SGA (OR=1.9; 90% CI: 1.3-2.8) compared with the rest of Idaho. During the pre- and post-fire periods, the ORs for TLBW were 0.8 and 1.3, respectively, and for SGA, 1.0, and 1.3, respectively. During the high-exposure period, TMBW for the exposed group was 71 g lower than in the comparison group. The TMBW in the exposed group was 8 g lower in the pre-fire period and 26 g lower in the post-fire period than in the comparison group. The study found no increased risk for preterm birth in the exposed group. Maternal exposures to airborne lead emissions appeared to be associated with increased risks for SGA, TLBW, and reduced TMBW.

To compare the accuracy of the commercial Fitbit Flex device (FF) with polysomnography (PSG; the gold-standard method) in insomnia disorder patients and good sleepers. Participants wore an FF and actigraph while undergoing overnight PSG. Primary outcomes were intraclass correlation coefficients (ICCs) of the total sleep time (TST) and sleep efficiency (SE), and the frequency of clinically acceptable agreement between the FF in normal mode (FFN) and PSG. The sensitivity, specificity, and accuracy of detecting sleep epochs were compared among FFN, actigraphy, and PSG. The ICCs of the TST between FFN and PSG in the insomnia (ICC=0.886) and good-sleepers (ICC=0.974) groups were excellent, but the ICC of SE was only fair in both groups. The TST and SE were overestimated for FFN by 6.5min and 1.75%, respectively, in good sleepers, and by 32.9min and 7.9% in the insomnia group with respect to PSG. The frequency of acceptable agreement of FFN and PSG was significantly lower (p=0.006) for the insomnia group (39.4%) than for the good-sleepers group (82.4%). The sensitivity and accuracy of FFN in an epoch-by-epoch comparison with PSG was good and comparable to those of actigraphy, but the specificity was poor in both groups. The ICC of TST in the FFN-PSG comparison was excellent in both groups, and the frequency of agreement was high in good sleepers but significantly lower in insomnia patients. These limitations need to be considered when applying commercial sleep trackers for clinical and research purposes in insomnia. Copyright © 2017 Elsevier Inc. All rights reserved.

Endometriosis is a chronic, estrogen-dependent condition that causes dysmenorrhea and pelvic pain. Elagolix, an oral, nonpeptide, gonadotropin-releasing hormone (GnRH) antagonist, produced partial to nearly full estrogen suppression in previous studies. We performed two similar, double-blind, randomized, 6-month phase 3 trials (Elaris Endometriosis I and II [EM-I and EM-II]) to evaluate the effects of two doses of elagolix - 150 mg once daily (lower-dose group) and 200 mg twice daily (higher-dose group) - as compared with placebo in women with surgically diagnosed endometriosis and moderate or severe endometriosis-associated pain. The two primary efficacy end points were the proportion of women who had a clinical response with respect to dysmenorrhea and the proportion who had a clinical response with respect to nonmenstrual pelvic pain at 3 months. Each of these end points was measured as a clinically meaningful reduction in the pain score and a decreased or stable use of rescue analgesic agents, as recorded in a daily electronic diary. A total of 872 women underwent randomization in Elaris EM-I and 817 in Elaris EM-II; of these women, 653 (74.9%) and 632 (77.4%), respectively, completed the intervention. At 3 months, a significantly greater proportion of women who received each elagolix dose met the clinical response criteria for the two primary end points than did those who received placebo. In Elaris EM-I, the percentage of women who had a clinical response with respect to dysmenorrhea was 46.4% in the lower-dose elagolix group and 75.8% in the higher-dose elagolix group, as compared with 19.6% in the placebo group; in Elaris EM-II, the corresponding percentages were 43.4% and 72.4%, as compared with 22.7% (P<0.001 for all comparisons). In Elaris EM-I, the percentage of women who had a clinical response with respect to nonmenstrual pelvic pain was 50.4% in the lower-dose elagolix group and 54.5% in the higher-dose elagolix group, as compared with 36.5% in the placebo group (P<0.001 for all comparisons); in Elaris EM-II, the corresponding percentages were 49.8% and 57.8%, as compared with 36.5% (P=0.003 and P<0.001, respectively). The responses with respect to dysmenorrhea and nonmenstrual pelvic pain were sustained at 6 months. Women who received elagolix had higher rates of hot flushes (mostly mild or moderate), higher levels of serum lipids, and greater decreases from baseline in bone mineral density than did those who received placebo; there were no adverse endometrial findings. Both higher and lower doses of elagolix were effective in improving dysmenorrhea and nonmenstrual pelvic pain during a 6-month period in women with endometriosis-associated pain. The two doses of elagolix were associated with hypoestrogenic adverse effects. (Funded by AbbVie; Elaris EM-I and EM-II ClinicalTrials.gov numbers, NCT01620528 and NCT01931670 .).

We compared the clinical outcomes of proton beam radiotherapy (PBRT) and those of conventional chemoradiotherapy via hyper-fractionated acceleration radiotherapy (HART) after induction chemotherapy in patients with locally advanced pancreatic cancer (LAPC). Twenty-five consecutive patients with LAPC received induction chemotherapy comprising gemcitabine and S-1 before radiotherapy. Of these, 15 and 10 were enrolled in the HART and PBRT groups, respectively. Moderate hematological toxicities were observed only in the HART group, whereas two patients in the PBRT group developed duodenal ulcers. All patients underwent scheduled radiotherapy, with overall disease control rates of 93% and 80% in the HART and PBRT groups, respectively. Local progression was observed in 60% and 40% of patients in the HART and PBRT groups, respectively. However, there was no statistical significance between the two groups regarding the median time to progression (15.4 months in both) and the median overall survival (23.4 v.s. 22.3 months). PBRT was feasible and tolerable, and scheduled protocols could be completed with careful attention to gastrointestinal ulcers. Despite the lower incidence of local recurrence, PBRT did not yield obvious progression control and survival benefits relative to conventional chemoradiotherapy. Copyright © 2017 IAP and EPC.

The triazole antifungal itraconazole may be cost prohibitive in brand name form; therefore, compounded and generic products are often used as alternatives. Itraconazole blood concentrations have not been studied in clinical patients receiving these formulations. Itraconazole bioassay was performed on serum/plasma from 95 dogs and 20 cats receiving itraconazole (compounded from bulk powder, generic pelletized, or brand name) for systemic mycosis treatment. Mean itraconazole concentration was lower in the compounded group (n = 42) as compared with the generic (n = 40) or brand name (n = 33) groups (0.5 µg/mL versus 8.3 µg/mL and 6.5 µg/mL, respectively; P < .001). No statistical difference was observed between itraconazole concentrations in the generic and brand name groups. Forty animals (95.2%) in the compounded group had subtherapeutic (<1.0 µg/mL) values. All cats in this group (n = 10) had undetectable itraconazole concentrations. Some animals in the generic and brand name groups had subtherapeutic values (12.5 and 12.1%, respectively) or potentially toxic values (>10 µg/mL; 37.5 and 24%, respectively). Compounded itraconazole should be avoided, but generic itraconazole appears to serve as a reasonable alternative to brand name itraconazole. Therapeutic drug monitoring may be beneficial in all cases.

The aim of this study was to compare the outcome of intracytoplasmic sperm injection (ICSI) and embryo transfer between couples with infertility due to male non-obstructive azoospermia (NOA) and obstructive azoospermia (OA). A retrospective analysis of 234 couples with azoospermia who were treated by ICSI and embryo transfer between January 2007 and October 2010 was performed. There were 61 couples in NOA group and 173 couples in OA group. Fertilization rates, pregnancy and clinical pregnancy rates were the main outcome measures. The number of retrieved mature oocytes, injected oocytes, metaphase II (MII) oocytes, two distinct pronuclei oocytes, cleavage embryos and embryos transferred was not significantly different between the groups. The fertilization rate was significantly lower in NOA group when compared to OA group (56.2 vs. 66.7%, respectively; p = 0.013) and the pregnancy rate was significantly lower in NOA group than OA group (36.1 vs. 50.9%, respectively; p = 0.046). The clinical pregnancy rates were not statistically different between the patients with NOA and OA azoospermia groups (24.6 vs. 36.4%, respectively; p = 0.09). This study suggests that ICSI and embryo transfer together with testicular sperm extraction results in statistically significant lower fertilization and pregnancy rates in men with NOA when compared to men with OA.

There is a widespread clinical view that stuttering is associated with high levels of muscles activity. The proposal of this research was to compare stutterers and fluent speakers with respect to the electromyographic activity of the upper and lower lip muscles. Ten individuals who stutter and 10 fluent speakers (control group) paired by gender and age were studied (mean age: 13.4 years). Groups were defined by the speech sample analysis of the ABFW-Language Test. A K6-I EMG (Myo-tronics Co., Seattle, WA, USA) with double disposable silver electrodes (Duotrodes, Myo-tronics Co., Seattle, WA) being used in order to analyze lip muscle activity. The clinical conditions investigated were movements during speech, orofacial non-speech tasks, and rest. Electromyographic data were normalized by lip pursing activity. The non-parametric Mann-Whitney test was used for the comparison of speech fluency profile, and the Student t-test for independent samples for group comparison regarding electromyographic data. There was a statistically significant difference between groups regarding speech fluency profile and upper lip activity in the following conditions: lip lateralization to the right and to the left and rest before exercises (P<0.05). There was no significant difference between groups regarding lower lip activity (P>0.05). The EMG activity of the upper lip muscle in the group with stuttering was significantly lower than in the control group in some of the clinical conditions analyzed. There was no significant difference between groups regarding the lower lip muscle. The subjects who stutter did not present higher levels of muscle activity in lip muscles than fluent speakers.

In Norway almost all pregnant women attend one routine ultrasound examination. Detection of fetal structural anomalies triggers psychological stress responses in the women affected. Despite the frequent use of ultrasound examination in pregnancy, little attention has been devoted to the psychological response of the expectant father following the detection of fetal anomalies. This is important for later fatherhood and the psychological interaction within the couple. We aimed to describe paternal psychological responses shortly after detection of structural fetal anomalies by ultrasonography, and to compare paternal and maternal responses within the same couple. A prospective observational study was performed at a tertiary referral centre for fetal medicine. Pregnant women with a structural fetal anomaly detected by ultrasound and their partners (study group,n=155) and 100 with normal ultrasound findings (comparison group) were included shortly after sonographic examination (inclusion period: May 2006-February 2009). Gestational age was >12 weeks. We used psychometric questionnaires to assess self-reported social dysfunction, health perception, and psychological distress (intrusion, avoidance, arousal, anxiety, and depression): Impact of Event Scale. General Health Questionnaire and Edinburgh Postnatal Depression Scale. Fetal anomalies were classified according to severity and diagnostic or prognostic ambiguity at the time of assessment. Median (range) gestational age at inclusion in the study and comparison group was 19 (12-38) and 19 (13-22) weeks, respectively. Men and women in the study group had significantly higher levels of psychological distress than men and women in the comparison group on all psychometric endpoints. The lowest level of distress in the study group was associated with the least severe anomalies with no diagnostic or prognostic ambiguity (p < 0.033). Men had lower scores than women on all psychometric outcome variables. The correlation in distress scores between men and women was high in the fetal anomaly group (p < 0.001), but non-significant in the comparison group. Severity of the anomaly including ambiguity significantly influenced paternal response. Men reported lower scores on all psychometric outcomes than women. This knowledge may facilitate support for both expectant parents to reduce strain within the family after detectionof a fetal anomaly.

Psychache can and does co-exist alongside resilience and coping amongst trauma survivors. This has been the center of the a-integrative theory of aging demonstrating an attitude to life based on cognitive and emotional dimensions. Aging of Holocaust survivors (HS) is especially difficult when focus is brought to the issue of integrating their life history. The present study aimed to investigate the interplay between psychache and resilience amongst aging HS. Cross-sectional study of HS and a matched comparison group recruited from the general population was carried out. All underwent a personal interview and endorsed quantifiable psychache and resilience scales. We enrolled 214 elderly participants: 107 HS and 107 comparison participants. Mean age for the participants was 80.7± years; there were 101 women and 113 men in each group. Holocaust survivors did not differ in the level of resilience from comparisons (mean: 5.82 ± 0.68 vs. 5.88 ± 0.55, respectively). Psychache was significantly more intense in the HS group (F(8,205) = 2.21; p < 0.05). The present study demonstrates the complex interplay between psychache and resilience. Aging HS still have to cope with high levels of psychache while realizing a life-long process of development through resilience.

The purpose of this study was to evaluate the effect of Er:YAG and Er,Cr:YSGG laser on tensile bond strength of composite resin to dentine in comparison with bur-prepared cavities. Fifteen extracted caries-free human third molars were selected. The teeth were cut at a level below the occlusal pit and fissure plan and randomly divided into three groups. Five cavities were prepared by diamond bur, five cavities prepared by Er:YAG laser, and the other group prepared by Er,Cr:YSGG laser. Then, all the cavities were restored by composite resin. The teeth were sectioned longitudinally with Isomet and the specimens prepared in dumbbelled shape (n = 36). The samples were attached to special jigs, and the tensile bond strength of the three groups was measured by universal testing machine at a speed of 0.5 mm/min. The results of the three groups were analyzed with one-way ANOVA and Tamhane test. The means and standard deviations of tensile bond strength of bur-cut, Er:YAG laser-ablated, and Er,Cr:YSGG laser-ablated dentine were 5.04 ± 0.93, 13.37 ± 3.87, and 4.85 ± 0.93 MPa, respectively. There is little difference in tensile bond strength of composite resin in Er,Cr:YSGG lased-prepared cavities in comparison with bur-prepared cavities, but the Er:YAG laser group showed higher bond strength than the other groups.

Training medical students in breaking bad news (BBN) in oncology may be key to improve patient care in an area where many physicians tend to be uncomfortable. Given the lack of evidence in the literature, this study aimed to assess empirically the impact of 2 teaching strategies to prepare students for the task of BBN in oncology: one-to-one simulated patient (SP) training with individual feedback (intervention group) vs small-group SP training with collective feedback (comparison group). Fourth-year students (N = 236) were randomly assigned to the intervention or comparison group. The SP videotaped interviews were analyzed with respect to BBN communication performance, rated using the Calgary-Cambridge checklist of teaching objectives for BBN; verbal interaction behaviors, coded with the Roter interaction analysis system; and 7 nonverbal behaviors. Students in the intervention group scored significantly higher after than before the training on the overall evaluation of the interview (P < .001) as well as on process skills (P < .001); they also obtained significantly higher scores compared to students in the comparison group on the overall evaluation of the interview (P < .001) and on process skills (P < .001). This study supports an individualized BBN teaching strategy and contributes to efforts to find the best way to train and reach the largest number of future physicians to improve communication competences in oncology.

As morbid obesity increasingly affects Hispanic Americans, the incidence of bariatric procedures among this population is rising. Despite this, prospective research on the effects of comprehensive postoperative education-centered interventions on weight loss and physical activity focused on Hispanic Americans is lacking. To examine whether a comprehensive nutrition education and behavior modification intervention improves weight loss and physical activity in Hispanic Americans with obesity following Roux-en-Y gastric bypass surgery (RYGB). A prospective randomized-controlled trial was conducted between November 2008 and April 2010. At 6 months following RYGB, 144 Hispanic Americans with obesity were randomly assigned to a comprehensive nutrition and lifestyle educational intervention (n=72) or a noncomprehensive approach (comparison group n=72). Those in the comprehensive group received education sessions every other week for 6 weeks in small groups and frequent contact with a registered dietitian. Those in the comparison group received brief, printed healthy lifestyle guidelines. Patients were reassessed at 12 months following surgery. Main outcome measures were excess weight loss and physical activity changes over time. Statistical analyses used t test, ?(2) test, Wilcoxon signed rank, Mann-Whitney U test, and intent-to-treat analysis, significance P<0.05. Participants (mean age 44.5 ± 13.5 years) were mainly Cuban-born women (83.3%). Mean preoperative excess weight and body mass index (calculated as kg/m(2)) were 72.20 ± 27.81 kg and 49.26 ± 9.06, respectively. At 12 months following surgery, both groups lost weight significantly, but comprehensive group participants experienced greater excess weight loss (80% vs 64% from preoperative excess weight; P<0.001) and greater body mass index reduction (6.48 ± 4.37 vs 3.63 ± 3.41; P<0.001) than comparison group participants. Comprehensive group participants were significantly more involved in physical activity (+14 min/wk vs ?4 min/wk; P<0.001) than comparison group participants. Mean protein intake was significantly lower in the comparison group than that in the comprehensive group (P<0.024). Findings support the importance of comprehensive nutrition education for achieving more effective weight reduction in Hispanic Americans following RYGB.

Literature suggests that the percutaneous punctures for percutaneous nephrolithotomy (PCNL) must be performed at the papilla of the renal calix and a puncture at the infundibulum or the direction of the pelvis is not advisable because of increased hemorrhagic risk. A prospective randomized study was conducted to investigate the safety in terms of blood loss of the infundibular approach for PCNL. Patients with renal stones with an accumulative size of at least 2 cm were randomly assigned to one of two parallel groups to undergo PCNL with either papillary (Group 1) or infundibular (Group 2) renal access. The primary outcome measures were the reduction in hemoglobin on first postoperative day and the need for transfusion during the first postoperative month. Secondary endpoints included the operative and fluoroscopy time, number of accesses performed, overall complication rate, hospitalization time, and complications up to 3 months. In total, 27 and 28 patients were enrolled in Groups 1 and 2, respectively. Patient age, body mass index, and stone size were similar among the groups (p = 0.672, 0.256, and 0.889, respectively). Reduction in hemoglobin and transfusion rate did not differ among Groups 1 and 2 (p = 0.916, p = 1.0, respectively). Operative time was higher in the case of Group 1 (p = 0.027). The overall complications rate was 7.4% for Group 1 and 7.14% for Group 2. Hospitalization time was not significantly different in the study groups (p = 0.724). The infundibular approach for PCNL to the posterior middle renal calices is not associated with higher blood loss or transfusion rate in comparison with the respective approach to the fornix of the papilla when the currently described technique is performed.

Background: Microdose flare-up GnRH agonist and GnRH antagonist have become more popular in the management of poor ovarian responders (POR) in recent years; however, the optimal protocol for POR patients undergoing in vitro fertilization has still been a challenge. Methods: In this observational study design, two hundred forty four poor ovarian responders were retrospectively evaluated for their response to GnRH agonist protocol (group-1, n=135) or GnRH antagonist protocol (group-2, n=109). Clinical pregnancy rate was the primary end point and was compared between the groups. Student t-test, Mann Whitney U test and χ2-test were used to compare the groups. The p<0.05 was considered to show a statistically significant result. Results: The mean total gonadotropin doses were 3814±891 IU in group 1 and 3539±877 IU in group 2 (p=0.02). The number of metaphase-II oocytes (3.6±2.4 vs. 2.8±1.9, p=0.005) and implantation rates (27.8% vs. 18.8%, p=0.04) in group 1 and group 2, respectively were significantly different. The fertilization rate in group 1 and group 2 was 73% vs. 68%, respectively (p=0.5) and clinical pregnancy rate was 19.8% vs. 14.4%, respectively (p=0.13). Conclusion: The GnRH agonist microdose flare-up protocol has favorable outcomes with respect to the number of oocytes retrieved and implantation rate; nevertheless, the clinical pregnancy rate was found to be similar in comparison to GnRH antagonist protocol in poor ovarian responders. GnRH antagonist protocol appears to be promising with significantly lower gonadotropin requirement and lower treatment cost in poor ovarian responders. PMID:27478770

Assess the benefits of green renovation on self-reported health of primarily elderly residents of a low-income public housing apartment building. Using questions from the Medicare Health Outcomes Survey, we interviewed residents at baseline and 1 year after green renovation of their 101-unit building in Mankato, Minnesota, comparing self-reported mental and physical health outcomes of 2 sets of residents (all-ages: median, 66 years, n = 40; elder: median, 72 years, n = 22) with outcomes for 2 same-aged low-income Minnesota comparison groups taken from Medicare Health Outcomes Survey participants (n = 40 and 572, respectively). Mankato apartment building residents. Green renovation including building envelope restoration; new heating, electrical, and ventilation systems; air sealing; new insulation and exterior cladding; window replacement; Energy-Star fixtures and appliances; asbestos and mold abatement; apartment gut retrofits; low volatile organic chemical and moisture-resistant materials; exercise enhancements; and indoor no-smoking policy. Self-reported health status including Activities of Daily Living and Veteran's Rand 12 (VR-12) survey results; housing condition visual assessment; indoor environmental sampling; and building performance testing. The all-ages study group's mental health improved significantly more than the comparison group's mental health on the basis of mean number of good mental health days in the past month (P = .026) and mean VR-12 mental component score (P = .023). Sixteen percent fewer all-ages study group people versus 8% more comparison group people reported falls (P = .055). The elder study group's 9% improvement in general physical health was not statistically significantly better than the elder comparison group's decline (6%) (P = 0.094). Significantly fewer people in the all-ages group reported smoke in their apartments because of tobacco products (20% vs 0%, P = .005), likely reflecting the new no-smoking policy. Green healthy housing renovation may result in improved mental and general physical health, prevented falls, and reduced exposure to tobacco smoke.

The aim was to elucidate the impact of Royal Jelly (RJ) on behavioural patterns, feather cover, egg quality and some blood haematological indices in laying hens (58-64 weeks of age). A total of 108 Tetra Brown laying hens were used in the current trial. The birds were divided into three equal groups (36 birds each). The pure RJ was prepared for immediate injection subcutaneously, as follows: the first treated group (RJ 1 :100 mg/kg); the second treated group (RJ 2 :200 mg/kg); the control group. The eating and drinking activities in the RJ 2 group were significantly (p = .009 and .015 respectively) higher than the control and RJ 1 groups. Furthermore, the aggressive pecks, feather pecks and threating behaviour in the RJ 2 group were significantly (p = .005, .001 and .039 respectively) lower than the control and RJ 1 groups. Both RJ-treated groups had the best feather cover on the neck and abdomen regions (p = .010 and .001 respectively; Figure ). Both RJ-treated groups had a significantly higher eggshell ratio (p = .019) and shell thickness (p = .001) in comparison with the control group. The albumen height, Haugh units and yolk index in both RJ-treated groups were significantly greater than those recorded in the control group (p = .026, .001 and .022 respectively). The erythrocyte and total leucocyte counts in the RJ 2 group were significantly higher than those reported in the control and RJ 1 groups (p = .029 and .013 respectively); however, the heterophil/lymphocyte (H/L) ratio and heterophil % in both RJ-treated groups were significantly the lowest (p = .001 and .039). In conclusion, birds in the RJ 2 group had superior feather cover, welfare and behavioural indices, probably due to the impact of active flavonoids components of RJ on laying hen performance. Furthermore, the RJ-treated groups had significantly improved egg quality parameters and some blood haematological indices. © 2017 Blackwell Verlag GmbH.

Minimizing X-ray exposure during percutaneous nephrolithotomy (PCNL) is challenging. Using the single semirigid dilator, also called "one-shot" or "one-stage" is a good alternative to routine telescopic metal dilators to reduce X-ray exposure. Our aim was to compare the single semirigid one-shot dilator with a telescopic metal dilator in PCNL. The intraoperative status was evaluated in 100 consecutive patients randomly assigned to two equal groups undergoing PCNL either with the one-shot (group A) or telescopic technique (group B). No significant difference in stone burden and location existed between the groups (P > 0.05). The mean age of group A and group B was 44.8 ± 15 and 45.6 ± 14 years, respectively (P = 0.78). The mean operation time was 51.14 ± 40.85 min in group A and 57.00 ± 38.85 min in group B (P = 0.46). The mean X-ray exposure time was 41.2 ± 17 and 48.4 ± 15 s in group A and group B, respectively (P = 0.03). The stone-free rate was 94 % (n = 47) in group A and 84 % (n = 42) in group B (P = 0.10). The mean hemoglobin drop was 1.26 ± 0.09 and 1.44 ± 0.11 g/dl in group A and group B, respectively (P = 0.09). The one-shot technique is feasible, safe, and well tolerated in patients undergoing PCNL. In addition to lack of complications, the method also provides less radiation exposure for urologists and nursing teams.

To evaluate the effects of a high school peer educator training programme on the sexual behaviour and related psychosocial outcomes of peer educators. A total of 728 students from 15 randomly selected public high schools in the Western Cape, South Africa, with a peer education programme and 15 matched comparison schools were recruited, comprising 295 students in the intervention group and 433 students in the comparison arms of the study respectively. Age of sexual debut, use of condom at last sex and psychosocial outcomes such as decision making, goal orientation, critical thinking and self-esteem were measured at baseline and follow-up 18 months later. At follow-up, there were no significant differences in the age of sexual debut, use of condom at last sex, goal orientation, critical thinking and self-esteem scores of the peer educators compared to students in the comparison group. Decision-making scores were significantly higher in the peer educators, compared to students in the comparison group (adjusted difference between means 0.14, 95% CI 0.02 to 0.26). Even a highly intensive peer education training programme had limited effects for the peer educators themselves. It is clear that community factors, gendered power relations and poverty need to be addressed to have a lasting impact.

Early manifestations of pediatric inflammatory bowel disease (IBD) can be relatively nonspecific. Initial mucosal biopsies may not be conclusive, delaying the diagnosis until subsequent biopsies demonstrate typical histologic features of IBD. We hypothesized that certain inflammatory cell types may be utilized as early histologic indicators of IBD in children. A retrospective analysis compared histologic findings from initially inconclusive or negative endoscopic studies in 22 patients who were subsequently diagnosed with IBD (after diagnostic endoscopy) to those of 20 comparison patients with functional abdominal pain matched for age, gender, and study type. A pediatric pathologist, blinded to study group, reviewed biopsies for histologic abnormalities. Eosinophil densities were obtained from the stomach, duodenum, and rectosigmoid areas. Immunohistochemistry (IHC) staining for tumor necrosis factor-α (TNF-α) and matrix metalloproteinase-9 (MMP-9) was performed on the stomach and rectosigmoid areas. Gastritis and colonic crypt distortion were present in the IBD group at a greater rate (61 % vs. 22 %, p = 0.020; 34 % vs. 4 %, p = 0.008, respectively). Peak and mean eosinophil densities in the rectosigmoid area were greater in the IBD group (17.0/hpf vs. 5.0/hpf, p = 0.0063; 12.3/hpf vs. 4.2/hpf, p = 0.0106, respectively). TNF-α and MMP-9 staining did not reveal any significant differences. Our data suggests that significantly greater inflammation in the stomach, crypt distortion in the colon, and eosinophilia in the rectosigmoid distinguished the IBD group from the comparison group at the time of the initial endoscopic evaluation.

This study aimed to compare performance metrics for immediate and delayed batch interpretation of screening tomosynthesis mammograms. This HIPAA compliant study was approved by institutional review board with a waiver of consent. A retrospective analysis of screening performance metrics for tomosynthesis mammograms interpreted in 2015 when mammograms were read immediately was compared to historical controls from 2013 to 2014 when mammograms were batch interpreted after the patient had departed. A total of 5518 screening tomosynthesis mammograms (n = 1212 for batch interpretation and n = 4306 for immediate interpretation) were evaluated. The larger sample size for the latter group reflects a group practice shift to performing tomosynthesis for the majority of patients. Age, breast density, comparison examinations, and high-risk status were compared. An asymptotic proportion test and multivariable analysis were used to compare performance metrics. There was no statistically significant difference in recall or cancer detection rates for the batch interpretation group compared to immediate interpretation group with respective recall rate of 6.5% vs 5.3% = +1.2% (95% confidence interval -0.3 to 2.7%; P = .101) and cancer detection rate of 6.6 vs 7.2 per thousand = -0.6 (95% confidence interval -5.9 to 4.6; P = .825). There was no statistically significant difference in positive predictive values (PPVs) including PPV1 (screening recall), PPV2 (biopsy recommendation), or PPV 3 (biopsy performed) with batch interpretation (10.1%, 42.1%, and 40.0%, respectively) and immediate interpretation (13.6%, 39.2%, and 39.7%, respectively). After adjusting for age, breast density, high-risk status, and comparison mammogram, there was no difference in the odds of being recalled or cancer detection between the two groups. There is no statistically significant difference in interpretation performance metrics for screening tomosynthesis mammograms interpreted immediately compared to those interpreted in a delayed fashion.

Introduction: Coronary artery bypass surgery (CABG) is associated with ischemia-reperfusion injury and tissue damage. CoQ10 as an antioxidant has an important role and may have cardio-protective effects after myocardial dysfunction and CABG. We aimed to evaluate whether CoQ10 has a myocardial cardio protective impact on cardiac biomarkers after CABG. Methods: In this double-blind study, 80 patients with coronary artery disease (CAD) who underwent CABG surgery were divided into intervention and control groups and received Q10 supplement or placebo, respectively. The surgical characteristics of the patients in the two groups were similar. The intervention group received 150 mg of Q10 supplement per day for 7 days before the surgery. The control group received placebo capsule. After operation the inter- and intra-group blood levels of CK-MB and troponin, before and after supplementation and 12 hours after the CABG, and postoperative outcomes such as intensive care unit (ICU) stay and hospital stay were compared. Results: In this study, 40 subjects were located in each group. The participation rate was 97.5% and men and women accounted for 52.5% and 47.5% respectively. The mean age of the subjects was 58.17 ± 8.55. The two groups were not significantly different in terms of basic variables. Within-group comparison showed a significant increase in the level of troponin enzymes over time (P < 0.001) and CK-MB (P < 0.001). However, between-group comparison showed no significant difference between the two groups in terms of CK-MB (P = 0.384) and troponin (P = 0.115). In the end, no interaction was observed between the intervention and time on CK-MB (P = 0.095) and troponin (P = 0.198) variables. Conclusion: Q10 supplementation 7 days before surgery was not effective in reducing CK-MB and troponin after CABG. PMID:27069560

To evaluate the long-term effectiveness and safety of repaglinide, a novel prandial glucose regulator, in comparison with glipizide in the treatment of patients with Type 2 diabetes. Diet or tablet-treated patients with Type 2 diabetes (n = 256; age 40-75 years, body mass index (BMI) 20-35 kg/m2, HbA1c 4.2-12.8%), without signs of severe microvascular or macrovascular complications, were included in this double-blind, multicentre, parallel-group comparative trial. Patients were randomized at a 2:1 ratio to repaglinide, 1-4 mg at mealtimes, or glipizide, 5-15 mg daily. Changes in fasting blood glucose (FBG) and HbA1c during the 12 months of treatment showed a significant difference in favour of repaglinide. In oral hypoglycaemic agents (OHA)-naive patients, HbA1c decreased in the repaglinide and glipizide groups by 1.5% and 0.3%, respectively (P < 0.05 between groups). Fasting blood glucose decreased in the repaglinide group by 2.4 mmol/l and increased in the glipizide group by 1.0 mmol/l (P < 0.05 between groups). In the study population as a whole, repaglinide was able to maintain glycaemic control (HbA1c level) during the 1-year study period, whereas control deteriorated significantly with glipizide. Change in HbA1c from baseline was significantly better with repaglinide than with glipizide after 12 months (P < 0.05). In addition, FBG deteriorated significantly in the glipizide group compared with the repaglinide group (P < 0.05). No patients in either group experienced a major hypoglycaemic event; the number of patients experiencing minor hypoglycaemia was similar in the repaglinide and glipizide groups (15% and 19%, respectively). Repaglinide, given as a prandial glucose regulator, is shown to be an effective and safe treatment of patients with Type 2 diabetes, and is better than glipizide in controlling HbA1c and FBG levels, overall, and in OHA-naive patients.

This prospective randomized trial was carried out to test the efficacy of a specific intervention for reducing the extent of their malnutrition and to change behaviour of mothers relating to child-feeding practices, care-giving, and health-seeking practices under the Bangladesh Integrated Nutrition Project (BINP). The study was conducted in rural Bangladesh among 282 moderately-malnourished (weight-for-age between 61% and 75% of median of the National Center for Health Statistics standard) children aged 6-24 months. Mothers of the first intervention group received intensive nutrition education (INE group) twice a week for three months. The second intervention group received the same nutrition education, and their children received additional supplementary feeding (INE+SF group). The comparison group received nutrition education from the community nutrition promoters twice a month according to the standard routine service of BINP. The children were observed for a further six months. After three months of interventions, a significantly higher proportion of children in the INE and INE+SF groups improved (37% and 47% respectively) from moderate to mild or normal nutrition compared to the comparison group (18%) (p < 0.001). At the end of six months of observation, the nutritional status of children in the intervention groups improved further from moderate to mild or normal nutrition compared to the comparison group (59% and 86% vs 30%, p < 0.0001). As the intensive nutrition education and supplementation given were highly effective, more children improved from moderate malnutrition to mild or normal nutritional status despite a higher incidence of morbidity. The frequency of child feeding and home-based complementary feeding improved significantly (p < 0.001) in both the intervention groups after three months of interventions and six months of observation. Body-weight gain was positively associated with age, length-for-age, weight-for-length, frequency of feeding of khichuri, egg, and potato (p < 0.05). Ability of mothers to identify malnutrition improved from 15% to 99% in the INE group and from 15% to 100% in the INE+SF group, but reduced from 24% to 21% in the comparison group. Use of separate feed pots, frequency of feeding, and cooking of additional complementary feeds improved significantly in the INE and INE+SF groups compared to the comparison group after three months of interventions and six months of observation. It can be concluded from the findings of the study that intensive nutrition education significantly improves the status of moderately-malnourished children with or without supplementary feeding.

In this study we compared 33 IQ and age matched pairs of individuals with Aspergers Disorder (ASP) and high functioning autism (HFA) on measures of repetitive behavior. On the Repetitive Behavior Scale-Revised (RBS-R), the ASP and HFA groups showed no differences in RBS-R Intensity score (severity) score or Frequency score (number of problems present). This suggests that the two groups are similar with respect to the intensity or severity of repetitive behaviors and the presence of repetitive behaviors. At the item level there were no differences on scales typically associated with autism (Stereotyped Behavior) and ASP (Restricted Interests). Similarly, there were no differences between the groups on the Aberrant Behavior Checklist Stereotypy scale. These findings add to the body of literature showing that HFA and ASP fail to differ with respect to repetitive behaviors. The implications of the findings for neurobiologic and genetic studies are discussed.

A total of fifty-four test subjects divided into one control group and two experimental groups were used to study the effects of chlorpromazine and amphetamine upon the incidental memory, its accuracy, and possible dependence on the introversive or extroversive personality structure, respectively. It has been found that chlorpromazine tends to lessen the incidental memory in extent and increase the number of allomnesias or instances of inaccurate remembrance, whereas amphetamine has the effects of increasing the extent of the incidental memory and reducing the number of allomnesias. A comparison of the extent of the incidental memory with the structure of personality in respect of introversion or extroversion in the control group also showed significant differences, the incidental memory being of smaller extent in the case of introversion and greater extent in the case of extroversion.

The present study evaluated, for the first time, the effect of the commercial formulation Metarril(®) SP Organic of Metarhizium anisopliae plus 10% mineral oil to control Rhipicephalus microplus in a pen study. Three groups were formed with six animals each: the first group was exposed to Metarril(®) plus 10% mineral oil and 1% Tween 80; the second group was exposed to sterile distilled water, mineral oil and Tween 80 (oil control group); and the third group received no treatment (control group). The fungal formulation contained 1 × 10(8)conidiaml(-1). Each animal was sprayed with 3L of formulation. Fallen ticks were counted daily and a sample of 20 engorged females per day was incubated for assessment of biological parameters. Throughout the study period, Metarril(®) oil-based formulation showed an efficacy ranging from 19.20% to 67.39% in comparison with the control group; and from 8.18% to 61.38% in comparison with the oil control group. The average efficacy of Metarril(®) oil-based formulation was 47.74% and 40.89% in comparison with control and oil control groups, respectively. Changes in the biological parameters of engorged R. microplus females were observed in the first three days after treatment, with a significant reduction in hatching percentage and egg production index. We concluded that Metarril(®) SP Organic plus 10% mineral oil was efficient against R. microplus in pen studies. However, further in vivo studies are required to increase the efficacy and to establish a protocol for the use of this product in the field against the cattle tick. Copyright © 2014 Elsevier B.V.

A multicentre, double-blind, randomised, parallel group study was undertaken to investigate the efficacy and safety of aceclofenac (123 patients, 100 mg twice daily) in comparison to piroxicam (117 patients, 20 mg once daily and placebo once daily) in patients with osteoarthritis of the knee. The treatment period of two months was preceded by a washout period of one week duration. On completion of the study, patients in both aceclofenac and piroxicam-treated groups exhibited significant improvement in pain intensity and functional capacity of the affected knee, as represented by the Osteoarthritis Severity Index (OSI) (p < 0.0001 and p < 0.001 respectively). This was further substantiated following the patient's assessment of pain intensity using the Visual Analogue Scale (VAS), in which significant improvements were demonstrated at all time points for each treatment group (p < 0.001). Although both treatment groups showed a significant improvement in all investigator's clinical assessments (functional exploration of the knee, knee flexion and extension (EXT)), there were no significant differences between the groups. There was, however, a more rapid improvement in knee flexion in the aceclofenac group after 15 days of treatment. Both aceclofenac and piroxicam were well tolerated by patients, the most commonly reported adverse events being gastrointestinal, although their incidence was low. Only 24 patients on aceclofenac, as opposed to 33 on piroxicam complained of dyspepsia, epigastralgia and pyrosis. While 7 patients in each group were withdrawn because of adverse events, only one patient with piroxicam was withdrawn because of severe upper gastrointestinal bleeding. Twice as many reports of fecal blood loss were made in the piroxicam group in comparison to the aceclofenac group. In summary, this study confirms the therapeutic efficacy of aceclofenac and suggests that it is a well-tolerated alternative NSAID to piroxicam in the treatment of osteoarthritis.

Colorectal cancer (CRC) is the second and third leading cause of cancer death for Hispanic men and women, respectively. CRC can be prevented if precursors are detected early and removed and can be successfully treated if discovered early. While one-on-one interventions for increasing CRC screening (CRCS) are recommended, few studies specifically assess the effectiveness of lay health worker (LHW) approaches using different educational materials. To develop and evaluate the effectiveness of two LHW-delivered CRCS interventions known as Vale la Pena (VLP; "It's Worth It!") on increasing CRCS among Hispanics. The study design was a cluster randomized controlled trial with two treatment arms. Six hundred and sixty five Hispanics 50 years and older were recruited from 24 colonias (neighborhoods) in the Lower Rio Grande Valley of the Texas-Mexico border. The interventions were a small media print intervention (SMPI) (including DVD and flipchart), and a tailored interactive multimedia intervention (TIMI) delivered on tablet computers. A no intervention group served as the comparison group. Data were collected between 2007 and 2009 and analyzed between 2009 and 2013. Measures assessed CRCS behavior, self-efficacy, knowledge, and other psychosocial constructs related to CRCS and targeted through VLP. Among participants reached for follow-up, 18.9 % in the SMPI group, 13.3 % in the TIMI group, and 11.9 % in the comparison group completed CRCS. Intent-to-treat analysis showed that 13.6 % in the SMPI group, 10.2 % in the TIMI group, and 10.8 % in the comparison group completed CRCS. These differences were not statistically significant. Results indicated that there are no significant differences in CRCS uptake between groups.

Objectives. To investigate self-reported health-related quality of life (HrQoL) in children and adolescents with chronic medical conditions compared with siblings/peers. Methods. Group 1 (6 treatment centers) consisted of 74 children/adolescents aged 8–16 years with hereditary bleeding disorders (HBD), 12 siblings, and 34 peers. Group 2 (one treatment center) consisted of 70 children/adolescents with stroke/transient ischemic attack, 14 siblings, and 72 peers. HrQoL was assessed with the “revised KINDer Lebensqualitätsfragebogen” (KINDL-R) questionnaire. Multivariate analyses within groups were done by one-way ANOVA and post hoc pairwise single comparisons by Student's t-tests. Adjusted pairwise comparisons were done by hierarchical linear regressions with individuals nested within treatment centers (group 1) and by linear regressions (group 2), respectively. Results. No differences were found in multivariate analyses of self-reported HrQoL in group 1, while in group 2 differences occurred in overall wellbeing and all subdimensions. These differences were due to differences between patients and peers. After adjusting for age, gender, number of siblings, and treatment center these differences persisted regarding self-worth (p = .0040) and friend-related wellbeing (p < .001). Conclusions. In children with HBD, HrQoL was comparable to siblings and peers. In children with stroke/TIA HrQoL was comparable to siblings while peers, independently of relevant confounder, showed better self-worth and friend-related wellbeing. PMID:27294108

Improving knowledge regarding injuries sustained by pediatric dancers is important in order to better understand injury risk. The aim of this study is to analyze dance injury etiology and body area by age in a cohort of young female dancers presenting to a pediatric sports/dance medicine clinic. The cross-sectional epidemiological study of a 5% probability sample of dancers evaluated between 1/1/2000 and 12/31/2009 with a musculoskeletal injury requiring physician evaluation. A total of 2,133 charts were reviewed from which 171 female dancers 8-17 years old (mean age 14.7 years) were identified. Data were stratified by age, < 12 years and ≥ 12 years, and analyzed based on injury body area, type, and etiology. Fisher's exact test was used to determine statistical significance. Injuries sustained by dancers in the younger age category (< 12 years) were largely to the foot-ankle/lower leg/knee (93.3%) versus thigh-hip/spine/upper extremity (6.7%). In comparison, dancers in the older age group (≥ 12 years) had a large proportion of injuries to the foot-ankle/lower leg/knee (67.3%) as well, but had a notably larger fraction of injuries to the thigh-hip/spine/upper extremity (32.7%; p = 0.04). Approximately two-thirds of the injuries sustained in the younger age group (< 12 years) were classified as bony. In comparison, injuries in the older age group (≥ 12 years) were roughly half bony and half soft tissue (51.3% and 48.7%, respectively; p = 0.29). Most injuries were overuse in etiology for both younger and older age groups (86.7% and 82.1%, respectively; p = 1.00). Through puberty, there was a decline in the injuries to the foot-ankle/lower leg/knee. Conversely, there was an increase in the thigh/hip-pelvis/spine/upper extremity injuries through growth. Injuries to young female dancers in this study cohort were mostly categorized as overuse in etiology, and differed by the age group and the body area. Increased information regarding dance injuries can help guide future injury prevention efforts.

Prevalence of allergies is different around the world. Allergic rhinitis is a common chronic disease in children. Intelligence quotient (IQ) is an indicator of efficacy and many factors including chronic diseases may affect it. This study compares the IQs of children diagnosed with persistent or perennial allergic rhinitis with healthy children. This was a comparative study that was conducted from June 2011-May 2013 in an academic referral clinic. In this study, 90 patients aged 6- to 14-yearsold who were diagnosed with persistent or perennial allergic rhinitis and were compared to 90 age and gender match healthy patients from their respective families. The Wechsler Intelligence Scale for Children was used to divide and calculate overall IQ, verbal IQ, and practical IQ. The t-test and chi square were used to analyze quantitative variables and qualitative variables, respectively. In this study, out of total 180 children, 90 (50%) in the case group and 90 children (50%), the control group participated for IQ comparison. One hundred (57%) were male and 80 (43%) were female. The overall IQ for allergic rhinitis patients and healthy patients was 109.2 and 107.5, respectively. This difference was not considered significant. Furthermore, there was no significant difference between the IQ scores of males and females. Although allergic rhinitis is a chronic disease and effects quality of life, there were no identifiable negative effects on IQ.

Abstract This retrospective study compared efficacy and safety of fludarabine combined with intermediate-dose cytarabine (FA regimen) versus high-dose cytarabine (HiDAC regimen) as consolidation therapy in acute myeloid leukemia (AML) patients who achieved complete remission. Disease-free survival (DFS) and overall survival (OS) based on age (≥60, <60 years) and cytogenetics were evaluated from data between January 2005 and March 2013. Total 82 patients (FA, n = 45; HiDAC, n = 37; 14–65 years) were evaluated. Five-year DFS was 32.0% and 36.2% for FA and HiDAC groups, respectively (P = 0.729), and 5-year OS was 39.5% and 47.8% (P = 0.568), respectively. Among older patients (≥60 years), 3-year DFS was 26.0% for FA group and 12.5% for HiDAC group (P = 0.032), and 3-year OS was 34.6% and 12.5%, respectively (P = 0.026). In FA group, hematological toxicities were significantly lower. FA regimen was as effective as HiDAC regimen in patients with good/intermediate cytogenetics and significantly improved DFS and OS in older patients. PMID:25501050

To determine the short-term effectiveness of full kinematic chain manual and manipulative therapy (MMT) plus exercise compared with targeted hip MMT plus exercise for symptomatic mild to moderate hip osteoarthritis (OA). Parallel-group randomized trial with 3-month follow-up. Two chiropractic outpatient teaching clinics. Convenience sample of eligible participants (N=111) with symptomatic hip OA were consented and randomly allocated to receive either the experimental or comparison treatment, respectively. Participants in the experimental group received full kinematic chain MMT plus exercise while those in the comparison group received targeted hip MMT plus exercise. Participants in both groups received 9 treatments over a 5-week period. Western Ontario and McMasters Osteoarthritis Index (WOMAC), Harris hip score (HHS), and Overall Therapy Effectiveness, alongside estimation of clinically meaningful outcomes. Total dropout was 9% (n=10) with 7% of total data missing, replaced using a multiple imputation method. No statistically significant differences were found between the 2 groups for any of the outcome measures (analysis of covariance, P=.45 and P=.79 for the WOMAC and HHS, respectively). There were no statistically significant differences in the primary or secondary outcome scores when comparing full kinematic chain MMT plus exercise with targeted hip MMT plus exercise for mild to moderate symptomatic hip OA. Consequently, the nonsignificant findings suggest that there would also be no clinically meaningful difference between the 2 groups. The results of this study provides guidance to musculoskeletal practitioners who regularly use MMT that the full kinematic chain approach does not appear to have any benefit over targeted treatment.

To compare the outcomes of flexible ureterorenoscopy and lasertripsy (FURS) using digital and conventional FURS for kidney stones. From September 2007 to April 2011, 118 patients underwent FURS (by the same surgeon). The outcomes were compared between equal numbers of procedures (59 each) using a conventional flexible ureterorenoscope (C-FURS; Olympus URF-P5) and a digital flexible ureterorenoscope (D-FURS; Olympus URF-V). Although the deflection, working channel, and field view are similar in both, the initial and terminal diameter is 8.4F and 9.9F and 6.9F and 8.4F for the D-FURS and C-FURS, respectively. The mean stone fragmentation time was calculated by the size per operative time. The preoperative, operative, and postoperative data were retrospectively analyzed and compared. The patient demographics were comparable. The mean stone size was 12.8 and 12 mm in the C-FURS and D-FURS groups, respectively. The initial assessment of the entire pyelocaliceal system was possible in 58 of 59 cases (98%) in the C-FURS group and 56 of 59 cases (94%) in the D-FURS group. The mean operative time was significantly longer in the C-FURS group (53.8 ± 15.2 minutes vs 44.5 ± 14.9 minutes). The overall stone-free rate 1 month after the procedure was 86% in the C-FURS group and 88% in the D-FURS group. Although on comparison, the D-FURS had slightly limited maneuverability, comparable success rates can be achieved with both conventional and digital ureteroscopes. D-FURSs significantly reduced the operative time compared with C-FURSs. Copyright © 2013 Elsevier Inc. All rights reserved.

An ingrown toenail is a common, painful, and debilitating condition. This study aims to compare 2 surgical methods (partial matricectomy with curettage and electrocautery) in the treatment of ingrown toenails. A total of 92 ingrown nails of the big toe in 86 patients underwent partial matricectomy with curettage, whereas 57 ingrown nails of the big toe in 52 patients underwent partial matricectomy with electrocautery. Recurrence was observed in 2 toenails in the partial matricectomy with curettage group, whereas no recurrence was observed in the partial matricectomy with electrocautery group (p > .05). The mean period of postoperative pain was 2.3 and 3.1 days in the curettage group and the electrocautery group, respectively (p < .05). There was a significant difference in the duration of scar tissue inflammation (p < .05). Both surgical methods are safe treatment modalities with a high success rate. Partial matricectomy, which is achieved using curettage, seems to be superior to electrocautery in respect of reduced inflammation and duration of pain.

Backgrounds/Aims Liver resection is a curative procedure performed worldwide for hepatocellular carcinoma (HCC). Deciding on the appropriate resection range for postoperative hepatic function preservation is an important surgical consideration. This study compares survival outcomes of HCC patients who underwent anatomical or non-anatomical resection, to determine which offers the best clinical survival benefit. Methods One hundred and thirty-one patients underwent liver resection with HCC, between January 2007 and February 2015, and were divided into two groups: those who underwent anatomical liver resection (n=88) and those who underwent non-anatomical liver resection (n=43). Kaplan-Meier survival analysis and Cox regressions were used to compare the disease-free survival (DFS) and overall survival (OS) rates between the groups. Results The mean follow-up periods were 27 and 40 months in the anatomical and non-anatomical groups, respectively (p=0.229). The 3- and 5-year DFS rates were 70% and 60% in the anatomical group and 62% and 48% in the non-anatomical group, respectively. The 3 and 5-year OS rates were 94% and 78% in the anatomical group, and 86% and 80% in the non-anatomical group, respectively. The anatomical group tended to show better outcomes, but the findings were not significant. However, a relative risk of OS between the anatomical and non-anatomical group was 0.234 (95% CI, 0.061-0.896; p=0.034), which is statistically significant. Conclusions Although statistical significance was not detected in survival curves, anatomical resection showed better results. In this respect, anatomical resection is more likely to perform in HCC patients with preserve liver function than non-anatomical resection. PMID:26693235

To elucidate the research possibilities when merging data on maternal diet from the Danish National Birth Cohort (DNBC) and the Norwegian Mother and Child Cohort Study (MoBa), through comparison of (i) the methodology used for dietary assessment and (ii) the estimated intake of selected food groups in the two cohorts. Qualitative and quantitative comparison of the two dietary databases. Two national prospective pregnancy cohorts. Denmark, Norway. Comparison of food intake using food frequency questionnaires (FFQs). The FFQs had overlapping time windows and a majority of the questions in the two FFQs were comparable. Calculation principles shared similar features, including the software used and use of global questions to calibrate intakes of different food groups. A total of 63 food groups were defined that could be compared across the two cohorts; these were further aggregated down to 31 broader groups. A comparison of food intakes (grams/d) showed 39, 74 and 141% lower daily intakes of fish, potatoes and rice, respectively, in DNBC vs. MoBa and 39, 54 and 65% higher daily intakes of milk, butter and potatoes in DNBC vs. MoBa. For most other food groups, differences in consumption data were below 20%. The two FFQs are to a large extent compatible and substantial differences in dietary habits were observed between the two cohorts. This may strengthen studies using pooled analysis to examine diet-disease relations. This is a conclusion of great importance given the colossal and costly task involved to establish each of these two cohorts. © 2014 Nordic Federation of Societies of Obstetrics and Gynecology.

Posttraumatic stress disorder (PTSD) has been consistently associated with episodic memory deficits. To some extent, these deficits could be related to an impairment of metamemory in individuals with PTSD. This research consequently aims at investigating prospective (feeling-of-knowing, FOK) and retrospective (confidence) metamemory judgments for episodic information in PTSD. Twenty participants with PTSD and without depression were compared to 30 healthy comparison participants on metamemory judgments during an episodic memory task. The concordance between metamemory judgments and recognition performance was then assessed by gamma correlations. The results confirmed that PTSD is associated with episodic memory impairment. Regarding metamemory, gamma correlations indicated that participants with PTSD failed to accurately predict their future memory performance as compared to the comparison group (mean FOK gamma correlations: .23 vs. .42, respectively). Furthermore, participants with PTSD made less accurate confidence judgments than comparison participants (mean confidence gamma correlations: .62 vs. .74, respectively). Our results demonstrate an alteration of both prospective and retrospective metamemory processes in PTSD, which could be of particular relevance to future therapeutic interventions focusing on metacognitive strategies.

This study investigated the effect of extracts of different composites, glass ionomer cement (GIC)s and compomers on the viability of brine shrimp larvae. Ethanolic extracts of four dental composites (Z-100; Solitaire 2; Filtek P60 and Synergy), a conventional GIC (Ketac-Fil), a resin-modified glass ionomer cement (Vitremer), two compomers (F2000; Dyract AP), and a flowable compomer (Dyract Flow) were prepared from each material. Following evaporation of the ethanol, the extracts were resuspended in distilled water, which was then used to test the effects on the viability of brine shrimp larvae. For the composites, the extract of Synergy was the least toxic (88% viability) followed by the extracts of Solitaire 2, Z100 and P60 (75%, 67.5% and 50% viability, respectively). One-way ANOVA revealed highly significant differences between the resin composite materials (p<0.001). Follow-up comparison between the composite groups by Tukey's pairwise multiple-comparison test (alpha =0.05) showed that the extract of Synergy was significantly less toxic than the extracts of all the other materials except that of Solitaire 2. The compomers showed 100% lethality, while the percentage of viable larvae for the extracts of Ketac-Fil, and Vitremer were 32.3%, and 37.0%, respectively. One-way ANOVA revealed highly significant differences between the groups of materials (p<0.001). Follow-up comparison between the groups by Tukey's test (alpha = 0.05) showed that the toxic effect of the extracts of the compomers were significantly greater than that of Ketac-Fil, and Vitremer. The differences in the toxic effects of Vitremer and Ketac-Fil were not statistically significant. In conclusion, the toxicity of composite materials varied according to their chemical composition. Compomers were the most lethal materials to brine shrimp larvae followed by GICs and then composites.

To compare alterations of mitochondria DNA (mtDNA) copy number, single nucleotide polymorphisms (SNPs), and oxidative damage of mtDNA in clinically stable patients with major depressive disorder (MDD). Patients met DSM-IV diagnostic criteria for MDD were recruited from the psychiatric outpatient clinic at Changhua Christian Hospital, Taiwan. They were clinically stable and their medications had not changed for at least the preceding two months. Exclusion criteria were substance-induced psychotic disorder, eating disorder, anxiety disorder or illicit substance abuse. Comparison subjects did not have any major psychiatric disorder and they were medically healthy. Peripheral blood leukocytes were analyzed to compare copy number, SNPs and oxidative damage of mtDNA between the two groups. 40 MDD patients and 70 comparison subjects were collected. The median age of the subjects was 42 years and 38 years in MDD and comparison groups, respectively. Leukocyte mtDNA copy number of MDD patients was significantly lower than that of the comparison group (p = 0.037). MDD patients had significantly higher mitochondrial oxidative damage than the comparison group (6.44 vs. 3.90, p<0.001). After generalized linear model adjusted for age, sex, smoking, family history, and psychotropic use, mtDNA copy number was still significantly lower in the MDD group (p<0.001). MtDNA oxidative damage was positively correlated with age (p<0.001) and MDD (p<0.001). Antipsychotic use was negatively associated with mtDNA copy number (p = 0.036). The study is cross-sectional with no longitudinal follow up. The cohort is clinically stable and generalizability of our result to other cohort should be considered. Our study suggests that oxidative stress and mitochondria may play a role in the pathophysiology of MDD. More large-scale studies are warranted to assess the interplay between oxidative stress, mitochondria dysfunction and MDD.

Objective This study aims to examine the personality characteristics in parricide offenders, by using the Minnesota Multiphasic Personality Inventory (MMPI) test, which is commonly used in clinical medicine. Methods A total of 73 parricide offenders with schizophrenia who were admitted to National Forensic Hospital in Gongju city between September 2014 and February 2015, and 104 comparison schizophrenia patients who had been admitted to Dankook University Hospital in Cheonan city the same hospital, completed the Korean version of the MMPI. Results The parricide offender group showed significantly higher on L, F, Hs, Hy and Pd than the comparison group. The result of the regression analysis indicated that Pd and Si significantly increased the odd ratio of the sexual offender group by 2.77 times and 0.32 times, respectively (p=0.029 and p=0.023). The offenders of parricide may have developed the following characteristics: hypochondriasis, hysteria and psychopathic deviate. Conclusion These results suggested that the psychopatholgy in the offenders of parricide might be different, compared to the control group. PMID:28326114

Effective interventions to prevent work stress and to improve health, well-being, and performance of employees are of the utmost importance. This quasi-experimental intervention study presents a specific method for diagnosis of psychosocial risk factors at work and subsequent development and implementation of tailored work stress interventions, the so-called DISCovery method. This method aims at improving employee health, well-being, and performance by optimizing the balance between job demands, job resources, and recovery from work. The aim of the study is to quantitatively assess the effectiveness of the DISCovery method in hospital care. Specifically, we used a three-wave longitudinal, quasi-experimental multiple-case study approach with intervention and comparison groups in health care work. Positive changes were found for members of the intervention groups, relative to members of the corresponding comparison groups, with respect to targeted work-related characteristics and targeted health, well-being, and performance outcomes. Overall, results lend support for the effectiveness of the DISCovery method in hospital care. PMID:29438350

Specifically, we used a three-wave longitudinal, quasi-experimental multiple-case study approach with intervention and comparison groups in health care work. Positive changes were found for members of the intervention groups, relative to members of the corresponding comparison groups, with respect to targeted work-related characteristics and targeted health, well-being, and performance outcomes. Overall, results lend support for the effectiveness of the DISCovery method in hospital care.

Examined the effects of the type of value appealed to and valence of appeal on children's intentions to engage in toothbrushing, their self-report of toothbrushing frequency, and their plaque level. 98 fifth-grade students served as the participants. Slide shows appealed to either health- or socially oriented values and also differed with respect to valence (positive vs. negative). A control group received a message that provided basic dental health information. Group comparisons revealed that children who received the negative social appeal showed a significant improvement in plaque level. Only the negative social appeal group differed significantly from the control group on the dependent measures.

Visual evoked potentials (VEPs) were recorded from 25 10- to 13-year-old mildly mentally retarded children and compared with those from 31 control children of the same age-range. Correlations of VEPs with age were weak, but a relationship between VEPs and IQ was demonstrated for the control group. The retarded group had significantly longer latencies and higher amplitude peaks than the control group, with the differences occurring primarily over non-specific cortex and for secondary components. Analysis also showed that the retarded group were neurophysiologically heterogeneous. Since the same children had been analyzed earlier by quantitative EEG methods, comparisons are made with respect to these two methods of investigating brain function.

Maxillofacial injuries can result in psychological derangement, leading to post-traumatic stress disorder (PTSD), which is characterized by continual re-experiencing of any traumatic event in addition to numerous systemic complications. The objective of this study was to assess the incidence and severity of "PTSD-related depression" in patients with maxillofacial injuries and to identify the risk factors involved. This prospective study involved 88 patients with maxillofacial trauma who had only cosmetic deficits (group A), only functional deficits (group B), or cosmetic and functional deficits (group C). The psychological status of all patients was assessed before and after surgery using Zung's Self-Rating Depression Scale. Remission time also was analyzed. Data were analyzed with SPSS 22.0 using parametric methods. Comparison of mean values among groups was performed using 1-way analysis of variance followed by Tukey honest significance difference post hoc tests for multiple pairwise comparisons. To compare proportions, the χ 2 test was applied. The number of patients in groups A, B, and C was 11, 34 and 43, respectively. In the immediate post-trauma stage, all patients in group A showed severe depression; the percentages of patients with severe depression in groups B and C were 8.8 and 81.4%, respectively, which was statistically relevant. Depression scores of patients of all groups decreased gradually in the postsurgical phase. Patients with cosmetic defects consistently recorded higher depression scores at all intervals. The time taken for recovery from depression (remission time) was shorter for patients with only functional deficits (group B). Patients with maxillofacial injuries are prone to PTSD-related depression from functional and cosmetic deficits. The objectives of trauma management must be aimed at restoring pre-trauma form and function of the maxillofacial skeleton and the patient's psychological status.

This pilot study evaluated the feasibility and preliminary effectiveness of a 10-week WhatsApp-based intervention aimed at enhancing health-related physical fitness components and cardiovascular disease (CVD) risk factors compared with a face-to-face condition. Participants (N.=32) were assigned to one of three groups: training group (N.=16), mobile group (N.=7) and control group (N.=9). Training group and mobile group performed the same training program, based on strength training with elastics bands and aerobic exercise, during 10 weeks; only the delivery mode differed. The mobile group increased handgrip strength, aerobic capacity and decreased systolic blood pressure and heart rate after exercise though there were no significant differences respect to control group. The training group decreased significantly systolic blood pressure (P=0.038), diastolic blood pressure (P=0.005), mean arterial pressure (P=0.006) and heart rate after exercise (P=0.002), respect to control group. Comparison between training and mobile group showed that WhatsApp-based physical activity intervention was less effective than face-to-face condition. The results indicate that the use of an online social network produced slight changes in some health-related physical fitness components and CVD risk factors.

Stress reduction care is important for pregnant women to decrease obstetric complications and children's health problems after birth. The aim of this study is to clarify the physical and psychologic effects of inhalation aromatherapy on pregnant women. Essential oils with high linalool and linalyl acetate content that may be used during pregnancy were selected and among these, and the one preferred by the participant was used. This was a prospective, randomized, controlled trial. This trial was performed at a gynecology outpatient department in a hospital in Kyoto, Japan. The study included pregnant women in week 28 of a single pregnancy with a normal course. Participants were randomly assigned into an aromatherapy group and a control group. They were seated in the resting, seated position for 10 minutes. During the latter 5 minutes of each 10-minute session, aromatherapy inhalation was performed for the aromatherapy group. Before and after the intervention, the Profile of Mood States (POMS) was measured. During the trial, the heart-rate fluctuations were measured for the autonomic nervous system regulation. A total of 13 pregnant women participated in the trial. Seven (7) participants were assigned to the aromatherapy group and 6 participants to the control group. The results of the POMS were such that based on an intragroup comparison, significant differences were observed in the Tension-Anxiety score (p<0.05) and the Anger-Hostility score (p<0.05), and the respective improvements observed were due to aromatherapy. The results of the autonomic nervous system regulation were such that based on an intragroup comparison within the aromatherapy group, the parasympathetic nerve activity increased significantly (p<0.05). Aromatherapy inhalation using essential oils containing linalyl acetate and linalool was found to be effective for the POMS and parasympathetic nerve activity, based on an intragroup comparison. However, based on a comparison between the groups, no substantial difference was observed; hence, further study is necessary in the future.

Background: Treatment of chronic constipation is creating one of the major problems for doctors and patients. Pyridostigmine increases the gastrointestinal motility through the effects on cholinesterase. It seems that this mechanism can reduce chronic constipation. The aim of this study was to compare the effects of pyridostigmine and bisacodyl on chronic constipation. Methods: This study was conducted on 68 patients who suffered from chronic constipation. Patients were randomly divided into two groups of Pyridostigmine and bisacodyl in which each consisted of 34 patients, respectively. Bristol stool form score, straining defecation, the time of defecation, the number of defecation per week, sense of incomplete evacuation and self-digitation were collected by means of questionnaires and the data were compared. Results: Sixty-eight patients with the mean age of 68.12±84.49 were studied. The mean difference in the frequency of defecation per week, VAS score, the time to defecation and the Bristol Stool form Scale in pre and post-treatment were 4.33±1.88, 5.96±2.29, 12.30±7.95 min and 2.10±0.95 in pyridostigmine group and 2.96±1.81, 4.06±2.22, 6.67±5.23 min and 1.41±0.84 in bisacodyl group, respectively. The significant difference was observed in both pyridostigmine and bisacodyl groups (P=0.005, P=0.002, P=0.002 and P=0.005, respectively). 60% and 32.3 of patients in pyridostigmine and bisacodyl groups recovered from self-digitations, respectively. In pyridostigmine and bisacodyl groups, 66.7% and 32.3 of them had improvement in the sense of incomplete defecation, respectively. Conclusion: Pyridostigmine and bisacodyl significantly improved the symptoms of chronic constipation similarly. PMID:26958328

Surgical treatment for chondral defects of the knee in competitive running and jumping athletes remains controversial. This study evaluated the performance outcomes of professional basketball players in the National Basketball Association (NBA) who underwent microfracture. Data from 24 professional basketball players from 1997 to 2006 was obtained and analyzed. NBA player efficiency ratings (PER) were calculated for two seasons before and after injury. A control group of 24 players was used for comparison. Study group and control group demographics including age, NBA experience, and minutes per game demonstrated no statistical difference. Mean time to return to an NBA game was 30.0 weeks from the time of surgery. The first season after returning to competition PER and minutes per game decreased by 3.5 (P < 0.01) and 4.9 min (P < 0.05), respectively. The 17 players who continued to play two or more seasons after surgery, the average reduction in their PER and minutes per game was 2.7 (P > 0.05) and 3.0 min (P < 0.26), respectively. A multivariant comparison versus controls demonstrated that power rating during the 2 years after surgery decreased by 3.1 (P < 0.01); while minutes per game decreased by 5.2 (P < 0.001). Twenty-one percent (n = 5 of 24) of the players treated with microfracture did not return to competition in an NBA game. On return to competition player performance and minutes per game are diminished.

The purpose of this study was to evaluate the cross-language transfer of the emergent literacy skills of preschoolers who were Spanish-speaking language minority children in the context of an experimental intervention study. Ninety-four children were randomly assigned to either a control condition (High/Scope preschool curriculum) or to receive small-group pull-out instruction (Literacy Express Preschool Curriculum) in English or initially in Spanish and transitioning to English. We examined whether children's initial skills in one language moderated the impact of the intervention on those same skills in the other language at posttest. Results demonstrated that, for children in the English-only intervention condition, initial Spanish receptive vocabulary and elision skills moderated the impact of the intervention on English receptive vocabulary and elision skills at posttest, respectively. For children in the transitional intervention condition, initial English definitional vocabulary and elision skills moderated the impact of the intervention on Spanish definitional vocabulary and elision skills at posttest, respectively. Results for the vocabulary interactions, as well as the elision interaction for the English-only intervention group comparisons, supported the notion of transfer of specific linguistic information across languages. Results for elision interaction for the transitional intervention group comparisons supported language-independent transfer. Implications for the theory of cross-language transfer of emergent literacy skills are discussed. PMID:24019555

We performed 123I-FP-CIT/SPECT and ECD/SPECT in 30 patients with Parkinson's disease with dementia (PDD) and 30 patients with dementia with Lewy bodies (DLB) to evaluate whether presynaptic nigro-striatal function and/or cerebral perfusional pattern is different in these diseases. The striatal uptake of DAT tracer was statistically significantly lower in PDD and DLB with respect to control data (p < 0.0005), however no significant difference was found between PDD and DLB. Patients with PDD and DLB showed a significant reduction of rCBF (p < 0.001) in parieto-occipital and frontal areas, with respect to controls, but the comparison between the two groups did not result in any significant difference by SPM analysis. Finally no correlation was found between any regional perfusional changes and nigro-striatal dysfunction. We conclude that neither studies with 123I-FP-CIT nor ECD/SPECT were able to discriminate between DLB and PDD in vivo.

Purpose: To identify the prognostic role of adjuvant abdominal radiation therapy (RT) on oncologic outcomes as a part of multimodal treatment in the management of desmoplastic small round cell tumor (DSRCT) and to determine its impact according to the quality of surgical resection. Methods and Materials: All patients treated for primary abdominal DSRCT in 8 French centers from 1991 to 2014 were included. Patients were retrospectively staged into 3 groups: group A treated with adjuvant RT after cytoreductive surgery, group B without RT after cytoreductive surgery, and group C by exclusive chemotherapy. Peritoneal progression-free survival (PPFS), progression-free survival (PFS), andmore » overall survival (OS) were evaluated. We also performed a direct comparison between groups A and B to evaluate RT after cytoreductive surgery. Radiation therapy was also evaluated according to completeness of surgery: complete cytoreductive surgery (CCS) or incomplete cytoreductive surgery (ICS). Results: Thirty-seven (35.9%), thirty-six (34.9%), and thirty (28.0%) patients were included in groups A, B, and C, respectively. Three-year OS was 61.2% (range, 41.0%-76.0%), 37.6% (22.0%-53.1%), and 17.3% (6.3%-32.8%) for groups A, B, and C, respectively. Overall survival, PPFS, and PFS differed significantly among the 3 groups (P<.001, P<.001, and P<.001, respectively). Overall survival and PPFS were higher in group A (RT group) compared with group B (no RT group) (P=.045 and P=.006, respectively). Three-year PPFS was 23.8% (10.3%-40.4%) for group A and 12.51% (4.0%-26.2%) for group B. After CCS, RT improved PPFS (P=.024), but differences in OS and PFS were not significant (P=.40 and P=.30, respectively). After ICS, RT improved OS (P=.044). A trend of PPFS and PFS increase was observed, but the difference was not statistically significant (P=.073 and P=.076). Conclusions: Adjuvant RT as part of multimodal treatment seems to confer oncologic benefits for patients treated for abdominal DSRCT after cytoreductive surgery and perioperative chemotherapy.« less

The differentiation of 25 automotive clear coats was evaluated using pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). The samples were selected from eight different groups of samples which slightly differ in their infrared spectra. Most of the samples could be differentiated by visual inspection of the pyrograms. As an objective mean for evaluation a new software based on the comparison of chromatograms was tested for automatic classification considering retention times as well as mass spectra. The database was formed by the triplicate results of the set of the 25 samples. Normally a replicate measurement of a sample yields the best fit by library search. In addition, for most groups classification with moderate fits are obtained for samples belonging to the same group. Some samples are completely rearranged forming a new group of similar samples containing five samples from three different IR groups and four samples of three other groups, respectively. Furthermore detailed visual recognition of individual pyrolysis products allows subgrouping. Therefore, most samples can be differentiated from each other by Py-GC/MS. The exception were three sample groups containing two samples each, which could not be differentiated from each other neither by library search nor by recognition of minor individual pyrolysis products.

Debonding is a common occurrence in orthodontic treatment and a considerable number of orthodontists prefer to rebond the detached brackets because of economic issues. The aim of this study was to compare the microleakage beneath rebonded stainless steel brackets using two methods of adhesive removal namely sandblast and laser. Sixty human premolar teeth were randomly divided into three groups. Following bonding the brackets, group 1 served as the control group. Brackets in groups 2 and 3 were debonded, and adhesive removal from the bracket bases was done by means of sandblasting and Er-YAG laser, respectively. After rebonding, teeth in each group were stained with 2% methylene blue for 24 hours, sectioned and examined under a stereomicroscope. Marginal microleakage at the adhesive-enamel and bracket-adhesive interfaces in the occlusal and gingival margins was determined. Statistical analysis was done using the Kruskal-Wallis test. Comparison of the microleakage scores among the three groups revealed no statistically significant difference (P > 0.05). At the enamel-adhesive interface, the gingival margins in all groups showed higher microleakage while in the adhesive-bracket interface, the occlusal margin exhibited greater microleakage. Er-YAG laser irradiation and sandblasting for adhesive removal from the debonded brackets yielded clinically acceptable microleakage scores.

Paid caregivers possess an essential role in home care services. However, recruitment and retention issues are extensive within this workforce, largely in relation to poor working conditions. This article primarily focuses on the qualitative data extracted from a large randomised controlled trial in New Zealand and is supported by some quantitative findings. The aim was to explore paid caregiver perceptions of a restorative home care intervention in comparison with usual home care. The purpose of the qualitative exploration was to gather rich descriptive data that highlight differences between the two services with an emphasis on the workforce viewpoint. Four focus groups were undertaken with paid caregivers, two at baseline (4 and 5 participants in the control and intervention groups, respectively) and two at 14 months (eight participants in each focus group). Focus group data were collected in December 2005 and February 2007. A general inductive approach was used to analyse focus group transcripts. Two themes emerged from both the control and intervention focus groups: relationship with older people and issues with home care service delivery. A further two themes were pertinent to the intervention group: job satisfaction and preintervention. Findings revealed the intervention had a substantial positive impact on paid caregiver job satisfaction in comparison with usual care. This appeared to be due to improved training, increased support and supervision, and more flexibility. The intervention resulted in positive changes from the paid caregiver perspective and substantially reduced turnover in comparison with usual home care. However, both groups identified the need for further improvements to their working conditions. In addition, the need to regulate this vulnerable workforce is discussed. © 2011 Blackwell Publishing Ltd.

Pelvic girdle pain is a common complaint of pregnant women. There are limited data on comparison between the effectiveness of stabilizing exercises and lumbopelvic belt on the treatment of these patients. The objective of this study was to compare the effect of lumbopelvic belt plus information, home based pelvic girdle stabilizing exercises plus information and information alone on pain intensity, functional status and quality of life of pregnant women with pelvic girdle pain. In this randomized clinical trial pregnant women with pelvic girdle pain (n=105) were randomly allocated to three groups; Control group (n=35) that received general information, exercise group (n=31) that in addition to general information were asked to perform specific pelvic stabilizing exercises at home and belt group (n=31) that received non-rigid lumbopelvic belt and the information. The primary outcome variables were pain intensity and functional status of the participants which were measured using visual analogue scale and Oswestry Disability Index (ODI) respectively. Quality of life of participants was measured using WHOQOL-BREF questionnaire. All measurements were performed at baseline, 3 and 6 weeks after the study conduction. The pain intensity of patients in belt group in comparison to other groups was decreased significantly at both 3 and 6 weeks follow-ups. The mean score of ODI of patients in belt group was also improved more than exercise and control groups significantly. On base of our results, it can be found that in short term lumbopelvic belt and information in treatment of pregnant women with pelvic girdle pain is superior to exercise plus information or information alone.

This study compared the object descriptions of school-age children with high-functioning autism (HFA) with those of a matched group of typically developing children. Descriptions were elicited in a referential communication task where shared information was manipulated, and in a guessing game where clues had to be provided about the identity of an object that was hidden from the addressee. Across these tasks, increasingly complex levels of audience design were assessed: (1) the ability to give adequate descriptions from one's own perspective, (2) the ability to adjust descriptions to an addressee's perspective when this differs from one's own, and (3) the ability to provide indirect yet identifying descriptions in a situation where explicit labeling is inappropriate. Results showed that there were group differences in all three cases, with the HFA group giving less efficient descriptions with respect to the relevant context than the comparison group. More revealing was the identification of distinct adaptation profiles among the HFA participants: those who had difficulty with all three levels, those who displayed Level 1 audience design but poor Level 2 and Level 3 design, and those demonstrated all three levels of audience design, like the majority of the comparison group. Higher structural language ability, rather than symptom severity or social skills, differentiated those HFA participants with typical adaptation profiles from those who displayed deficient audience design, consistent with previous reports of language use in autism.

Functional Dissociation of Group III Metabotropic Glutamate Receptors Revealed by Direct Comparison between the Behavioral Profiles of Knockout Mouse Lines.

2015-05-21

Group III metabotropic glutamate receptors (mGlu4, mGlu7, mGlu8) display differential brain distribution, which suggests different behavioral functions. However, comparison across the available animal studies remains methodologically hazardous and controversial. The present report directly compares knockouts for each group III receptor subtype using a single behavioral test battery and multivariate analysis. The behavioral phenotypes of C57BL/6J mice lacking mGlu4, mGlu7, or mGlu8 and their respective littermates were examined using a multimetric test battery, which included elements of neuromotor performance, exploratory behavior, and learning and memory. Multivariate statistical methods were used to identify subtype-specific behavioral profiles and variables that distinguished between these mouse lines. It generally appears that mGlu7 plays a significant role in hippocampus-dependent spatial learning and in some fear-related behaviors, whereas mGlu4 is most clearly involved in startle and motivational processes. Excepting its influence on body weight, the effect of mGlu8 deletion on behavior appears more subtle than that of the other group III receptors. These receptors have been proposed as potential drug targets for a variety of psychopathological conditions. On the basis of these controlled comparisons, we presently conclude that the different group III receptors indeed have quite distinct behavioral functions. © The Author 2015.

To assess the effectiveness of videotape patient education, 22 patients were randomized to receive either videotape or personalized teaching for oral anticoagulant (warfarin) therapy. Both groups scored significantly higher on a questionnaire designed to assess knowledge gained after instruction, with no significant difference between the two groups. Videotape instruction required substantially less nursing time. A second questionnaire assessed patient satisfaction with respect to both methods, which were rated equally effective and worthwhile. Videotape teaching is an effective and well-accepted alternative form of patient education requiring significantly less personnel time.

Little information is available regarding medical utilization and cost in patients with overlap syndrome of chronic obstructive pulmonary disease (COPD) and asthma. The purpose of this study is to analyze medical utilization and cost in patients with overlap syndrome and to compare them to COPD patients without asthma. Using the 2009 Korean National Health Insurance (NHI) database, COPD patients were identified. Medical utilization and costs were also analyzed. Of a total of 185,147 patients identified with COPD, 101,004 patients were classified with overlap syndrome of COPD and asthma and 84,143 patients with COPD without asthma. In 2009, the percentages of emergency room visits, admissions, and intensive care unit admissions were 14.6%, 30.5%, and 0.5%, respectively, in the patients with overlap syndrome group and 5.0%, 14.1%, and 0.2%, respectively, in the COPD patients without asthma group (p < 0.05 for all comparisons). The cost of medical utilization was 790 ± 71 US dollars per person and 3,373 ± 4,628 dollars per person for outpatient and inpatient services, respectively, in the patients with overlap syndrome and 413 ± 512 and 3,010 ± 5,013, respectively, in the COPD patients without asthma (p < 0.05 for all comparisons). Multiple linear regression showed that age, sex, overlap syndrome, hospitalization in the last year, low socioeconomic status, and type of hospital use were significant factors affecting medical utilization and cost. In patients with overlap syndrome, both medical utilization and cost were higher than in COPD patients without asthma.

Purpose In 1995, the Children's Cancer Group (CCG) opened a trial for patients with Hodgkin's lymphoma evaluating whether low-dose involved-field radiation therapy (IFRT) improved event-free survival (EFS) for patients achieving a complete response after chemotherapy. We present the long-term study outcome using final data through March 2007. Patients and Methods Between January 1995 and December 1998, 826 eligible patients were enrolled onto CCG 5942. Four hundred ninety-eight patients achieving an initial complete response to chemotherapy were randomly assigned to receive IFRT or no further therapy. EFS and overall survival (OS) were assessed from the date of study entry or random assignment, as appropriate. Results Ten-year EFS and OS rates for the entire cohort were 83.5% and 92.5%, respectively. In an as-treated analysis for randomly assigned patients, the 10-year EFS and OS rates were 91.2% and 97.1%, respectively, for IFRT and 82.9% and 95.9%, respectively, for no further therapy. For EFS and OS comparisons, P = .004 and P = .50, respectively. Bulk disease, “B” symptoms, and nodular sclerosis histology were risk factors for inferior EFS. Conclusion With a median follow-up of 7.7 years, IFRT produced a statistically significant improvement in EFS but no improvement in OS. For individual patients, the relative risks of relapse versus late effects of IFRT must be considered. Patient and disease characteristics and early response assessment will aid in deciding which patients are most likely to benefit from IFRT. PMID:22649136

To evaluate the efficacy and safety of peripheral vitrectomy under air infusion in comparison with fluid infusion in patients undergoing 23-gauge pars plana vitrectomy for primary rhegmatogenous retinal detachment. A total of 80 eyes of 80 patients with primary rhegmatogenous retinal detachment were enrolled into the study. Forty cases underwent peripheral vitrectomy under air infusion (air group), and a control group of equal number underwent peripheral vitrectomy under fluid infusion (fluid group). Peripheral iatrogenic retinal breaks during peripheral vitrectomy, postoperative visual acuities, and retinal redetachment rates were compared. The number of eyes with peripheral iatrogenic retinal breaks in air group during peripheral vitrectomy was statistically comparable with that in fluid group (1/40 and 4/40, 2.5% and 10%, respectively; P = 0.16). Scleral depression was necessitated in 7 of 40 cases (17.5%) during the operation in the air group. There were no statistically significant differences between the groups in means of postoperative visual acuity and retinal redetachment (P = 0.18 and P = 1.0, respectively). Peripheral vitrectomy under air infusion for primary rhegmatogenous retinal detachment revealed comparable results with fluid infusion in terms of intraoperative and postoperative complications and surgical outcomes.

Matrix metalloproteinases are inflammatory biomarkers involved in carotid plaque instability. Our objective was to analyze the inflammatory activity of plasma and carotid plaque MMP-8 and MMP-9 after intravenous administration of hydrocortisone. The study included 22 patients with stenosis ≥ 70% in the carotid artery (11 symptomatic and 11 asymptomatic) who underwent carotid endarterectomy. The patients were divided into two groups: Control Group - hydrocortisone was not administered, and Group 1 - 500 mg intravenous hydrocortisone was administered during anesthetic induction. Plasma levels of MMP-8 and MMP-9 were measured preoperatively (24 hours before carotid endarterectomy) and at 1 hour, 6 hours and 24 hours after carotid endarterectomy. In carotid plaque, tissue levels of MMP-8 and MMP-9 were measured. Group 1 showed increased serum levels of MMP- 8 (994.28 pg/ml and 408.54 pg/ml, respectively; P=0.045) and MMP-9 (106,656.34 and 42,807.69 respectively; P=0.014) at 1 hour after carotid endarterectomy compared to the control group. Symptomatic patients in Group 1 exhibited lower tissue concentration of MMP-8 in comparison to the control group (143.89 pg/ml and 1317.36 respectively; P=0.003). There was a correlation between preoperative MMP-9 levels and tissue concentrations of MMP-8 (P=0.042) and MMP-9 (P=0.019) between symptomatic patients in the control group. Hydrocortisone reduces the concentration of MMP- 8 in carotid plaque, especially in symptomatic patients. There was an association between systemic and tissue inflammation.

Purpose To evaluate and compare the efficacy and tolerance of fibrin glue and sutures for closing conjunctival wounds in strabismus surgery. Methods In a prospective trial, we performed strabismus surgery using limbal incisions. Conjunctival wounds were closed with fibrin glue in 20 eyes of 20 patients (fibrin group) and 8-0 polyglactin suture in 20 eyes of 20 patients (suture group). Postoperative pain, tearing, and inflammation were compared at 1 day, 1 week, 3 weeks, and 6 weeks after surgery. Conjunctival incision healing was also investigated. Results One day and one week post-operatively, pain and tearing scores were lower in the fibrin group (p = 0.000, respectively). Mean surgery time was significantly shorter in the fibrin (48 ± 5 minutes) than the suture group (63 ± 7 minutes) (p = 0.000). Inflammation was significantly more severe in the suture group until 3 weeks postoperative (p = 0.000, respectively), but conjunctival healing did not differ between the groups. Hyperemia appeared more prominent in the fibrin group 3 and 6 weeks after surgery (p = 0.087 and 0.000, respectively). Two eyes in the fibrin group showed conjunctival gaps of more than 2 mm, which closed spontaneously by three weeks after surgery. No allergic reactions or infections developed. Conclusions Fibrin glue proved to be as effective as sutures in closing conjunctival wounds. It provides more comfortable early postoperative courses and might be considered as an alternative to sutures in strabismus surgery. PMID:21655043

To compare the fusion rate of a hydroxyapatite demineralized bone matrix (DBM) with post-laminectomy acquired autograft in lumbar interbody fusion surgery and to evaluate the correlation between fusion rate and clinical outcome. From January 2013 to April 2014, 98 patients underwent lumbar interbody fusion surgery with hydroxyapatite DBM (HA-DBM group) in our institute. Of those patients, 65 received complete CT scans for 12 months postoperatively in order to evaluate fusion status. For comparison with autograft, we selected another 65 patients who underwent lumbar interbody fusion surgery with post-laminectomy acquired autograft (Autograft group) during the same period. Both fusion material groups were matched in terms of age, sex, body mass index (BMI), and bone mineral density (BMD). To evaluate the clinical outcomes, we analyzed the results of visual analogue scale (VAS), Oswestry Disability Index (ODI), and Short Form Health Survey (SF-36). We reviewed the CT scans of 149 fusion levels in 130 patients (HA-DBM group, 75 levels/65 patients; Autograft group, 74 levels/65 patients). Age, sex, BMI, and BMD were not significantly different between the groups (p=0.528, p=0.848, p=0.527, and p=0.610, respectively). The HA-DBM group showed 39 of 75 fused levels (52%), and the Autograft group showed 46 of 74 fused levels (62.2%). This difference was not statistically significant (p=0.21). In the HA-DBM group, older age and low BMD were significantly associated with non-fusion (61.24 vs. 66.68, p=0.027; -1.63 vs. -2.29, p=0.015, respectively). VAS and ODI showed significant improvement after surgery when fusion was successfully achieved in both groups (p=0.004, p=0.002, HA-DBM group; p=0.012, p=0.03, Autograft group). The fusion rates of the hydroxyapatite DBM and Autograft groups were not significantly different. In addition, clinical outcomes were similar between the groups. However, older age and low BMD are risk factors that might induce non-union after surgery with hydroxyapatite DBM.

Furagin (a nitrofurantoin analogue) has the same efficacy in treating acute cystitis as ciprofloxacin, however the duration of therapy is longer. We established a hypothesis that therapy with ciprofloxacin results in faster resolution of mucosal inflammation in comparison with furagin. Rates of urinary secretion of immunoglobulins class A, M and G and interleukin-8 (IL-8) were evaluated before and after initiation of therapy in adult women presenting with acute cystitis confirmed by urine culture. Women were randomised into two groups receiving either ciprofloxacin 250mg twice a day for 3 days (n=13) or furagin 100mg three times a day for 7 days (n=14). Median lengths of follow-up were 4 days and 5 days in the ciprofloxacin and furagin groups, respectively. Treatment with ciprofloxacin resulted in faster eradication of pathogens. No bacteria or nitrates were detected in the ciprofloxacin group, whilst leukocyte esterase was positive in only one case. In the furagin group there were four positive cultures, seven cases with positive nitrates and five cases with positive esterase. Secretion rates of all four substances dropped significantly, but the changes over time were similar in both groups.

PURPOSE: To compare the efficacy of the olive tipped (OT) cannula to the conventional Steven's cannula for sub-Tenon block (STB) before cataract surgery. METHODS: This prospective, randomized, double-masked compared STB delivered in cataract surgery patients with an OT cannula or a conventional Steven's cannula (ST). Outcome variables included the akinesia score and lid movement scores at 5 and 10 min. The patient perception of pain during delivery of the STB and surgery were also compared between groups. Surgeon satisfaction with anesthesia was compared between groups. P <0.05 was statistically significant. RESULTS: There were sixty patients in each group. The age between groups was not statistically different (P = 0.4). The body mass index was higher in the ST group compared to the OT group (P < 0.001). The akinesia score at 5 and 10 min did not differ between groups (P = 0.07 and P = 0.6, respectively). The patient perception of pain during STB and surgery were similar between groups (P = 0.1 and P = 0.06, respectively). There were six patients with mild chemosis and redness in the OT group and 15 patients in the ST group. CONCLUSION: An OT cannula is equally effective as the conventional Steven's cannula for delivering STB anesthesia before cataract surgery. PMID:27994394

The Ellman group has been one of the most influential in the development and widespread adoption of combinatorial chemistry techniques for biomedical research. Their work has included substantial methodological development for library synthesis with a particular focus on new scaffolds rationally targeted to biomolecules of interest and biologically relevant natural products. Herein we analyze a representative set of libraries from this group with respect to their biological and biomedical relevance in comparison to existing drugs and probe compounds. This analysis reveals that the Ellman group has not only provided new methodologies to the community but also provided libraries with unique potential for further biological study. PMID:18343129

Gonadotropins and GnRH have been used to electively induce ovulation in llamas and alpacas, but critical evaluation of the natural interval to ovulation after mating has not been performed nor has a direct comparison of the effects of natural mating versus hormone treatments on this interval and subsequent luteal development. The objectives of this study were to compare the effects of hormonal treatments and natural mating on ovulation induction, interval to ovulation, and luteal development in llamas. The ovaries of llamas were examined by transrectal ultrasonography once daily. Llamas with a large follicle were assigned randomly to be: (1) mated with an intact male (mated; n=10); (2) given 5 mg of LH im (LH; n=11); or (3) 50 microg of GnRH im (GnRH; n=10). Ultrasound examinations were performed every 4h from treatment (day 0) to ovulation and thereafter once daily for 15 consecutive days to monitor CL growth and regression (n=5 per group). Plasma progesterone concentrations were measured at days 0, 3, 6, 9, and 12 after treatment to evaluate CL function. The size of the largest preovulatory follicle at the time of treatment did not differ among groups (11+/-0.6, 10.5+/-0.8, 11.8+/-0.9 mm, for mated, LH, and GnRH groups, respectively; P=0.6). No differences were detected among groups (mated, LH, and GnRH) in ovulation rate (80%, 91%, 80%, respectively; P=0.6), or interval from treatment to ovulation (30.0+/-0.5, 29.3+/-0.6, 29.3+/-0.7h, respectively; P=0.9). Similarly, no differences were detected among groups (mated, LH, and GnRH) in maximum CL diameter (14.2+/-0.3, 13.2+/-0.5, and 13.0+/-0.7 mm, respectively; P=0.5), the day of maximum CL diameter (7.6+/-0.2, 7.6+/-0.2, and 7.4+/-0.4 mm, respectively; P=0.6), or the day on which the CL began to regress (12.3+/-0.3 [non-pregnant, n=3], 11.8+/-0.6, 12.2+/-0.4, respectively; P=0.4). The diameter of the CL and plasma progesterone concentrations changed over days (P<0.0001) but the profiles did not differ among groups. In summary, ovulation rate, interval to ovulation, and luteal development were similar among llamas that were mated naturally or treated with LH or GnRH. We conclude that both hormonal preparations are equally reliable for inducing ovulation and suitable for synchronization for artificial insemination or embryo transfer program.

According to the optimal stimulation theory and the delay aversion hypothesis, children with attention deficit hyperactivity disorder (ADHD) experience difficulties when they are confronted with low levels of stimulation and delay, respectively. This study investigated the activity level of children with ADHD during waiting situations in the classroom. Three series of hypothesis were made: (1) with respect to the comparison between waiting and non-waiting intervals, (2) with respect to the effects of non-temporal stimulation, and (3) with respect to the effects of temporal stimulation on behaviour during waiting. The activity level of 14 children with ADHD and 14 control children between the ages of 6 and 11 years was observed during two non-waiting class situations and three waiting situations: without any stimulation, in the presence of nontemporal stimulation and in the presence of temporal stimulation. Both groups of children obtained higher activity scores for all behavioural dimensions during waiting compared with non-waiting situations. The results further revealed additive effects of waiting and diagnostic group on behaviour. Additional nontemporal stimulation during waiting affected the behaviour of all children for most behavioural characteristics. For noisiness, additive effects were also found for diagnostic group and either non-temporal stimulation or temporal stimulation. For restlessness, a trend for an interaction effect between diagnostic group and nontemporal stimulation was found. The findings have clear implications for school observations within an assessment protocol.

Paravertebral block (PVB) is an established technique for providing anesthesia for breast surgery. The primary objective was to compare anatomical landmark technique (ALT) to the ultrasound-guided (USG) PVB block for providing surgical anesthesia. Secondary objectives included comparison of perioperative analgesia and complications. This randomized, controlled, observer-blinded study included 72 females, aged 18 to 65 years, American Society of Anesthesiologists physical status I or II, undergoing elective unilateral breast surgery. Study participants were randomized to the ALT group or USG group. Ipsilateral PVB was performed with the respective technique from T1 to T6. Five milliliters of local anesthetic mixture (0.5% ropivacaine, 5 μg/mL adrenaline, 1 μg/kg clonidine) was administered at each level. Paravertebral catheter was inserted at T4/T3 level. After confirming sensory loss, patients were taken up for surgery with propofol sedation (20-50 μg/kg per minute). More patients in the USG group (34/36 [94.44%]) had a successful block as compared with the ALT group (26/36 [72.22%]) (P = 0.024). Difference in proportion was 18.1 (95% confidence interval, 0.15-36.0) (P = 0.024) after adjustment for age. More dermatomes were blocked in the USG group (P = 0.0018) with less sparing of upper T2 and T3 dermatomes (P = 0.003, P = 0.006, respectively). Median time to first postoperative analgesic requirement was 502.5 minutes (range, 195-1440 minutes) in the USG group versus 377.5 minutes (range, 215-1440 minutes) in the ALT group. Pain at rest and movement 2 and 4 hours postoperatively and number of catheter top-ups in 24 hours postoperatively were lesser in the USG group (P = 0.012). Complications were comparable. Ultrasound-guided PVB provided better anesthesia and perioperative analgesia than the landmark technique for breast surgery. The trial was registered retrospectively at the Clinical Trial Registry of India, CTRI/2015/05/005774.

Pediatric population has increasing incidence of renal calculus and it is estimated to be around 50/10,000 population. The treatment of choice for large and complex stone in anomalous kidney is percutaneous nephrolithotomy (PCNL). The fate of insignificant residual fragment after PCNL in pediatric patients is not well documented. Here, we are reporting our long-term experience and follow-up of insignificant residual fragment in pediatric patients with anomalous kidney in comparison to normal kidney. Intuitional ethical approval was taken. A retrospective analysis of PCNL in pediatric (<18 years) anomalous kidney was performed from 2001 to 2013. The data of 52 pediatric patients with anomalous kidney (group B) have been compared to 251 normal kidneys (group A). The mean age of the patients was 7.83 + 3.45 (range 3-18) in group A and 8.21 ± 3.25 (range 5-18) in group B. The mean size of the insignificant residual fragment was 2.2 + 0.5 mm (1-4) in group A and 2.1 + 0.6 mm (range 1-4) in group B. Most of these residual fragments were single in number (72.55 vs. 67.30%, respectively). 54.98% children in group A and 67.30% in group B were symptomatic in the follow-up. Stone size was increased, stable and spontaneously passed in 49.8 vs. 71.15, 22.7 vs. 19.23 and 27.49 vs. 9.61% (p < 0.03), respectively, over mean follow-up of 50.34 months. Insignificant residual fragments in children are notorious for regrowth (49.8% in normal and 71.15% in anomalous kidney) in future. Most of the children will require symptomatic treatment (55.37 vs. 82.69%) or reintervention (39 vs. 46%) for insignificant residual fragment.

Evaluation of the marginal fit of cemented zirconia copings manufactured after digital impression with Lava™ Chairside Oral Scanner in comparison to that of zirconia copings manufactured after conventional impressions with polyvinyl siloxane. A prepared typodont tooth #36, was replicated 40 times with a vinyl silicone and precise model resin. The dies were randomly divided into two groups according to the impression taking technique. Digital impressions with Lava™ C.O.S. and conventional impressions were taken according to the group. Subsequently zirconia copings were manufactured and cemented on their respective dies with zinc oxide phosphate cement. After embedding in resin, mesio-distal section of each coping was performed with a diamond saw in order to obtain two slices. One half of the specimen was used for evaluation with an optical microscope (OM) and the other half for evaluation with a scanning electron microscope (SEM). Marginal gap (MG) and absolute marginal discrepancy (AMD) were measured mesial and distal on each slice. No significant difference of the marginal parameters between the digital and the conventional group was found. The mean values for MG in the digital group were 96.28 μm (+/-43.21 μm) measured with the OM and 99.26 μm (+/-48.73 μm) measured with the SEM, respectively. AMD mean values were 191.54 μm (+/-85.42 μm) measured with the optical microscope and 211.6 μm (+/-96.55 μm) with the SEM. For the conventional group the mean MG values were 94.84 μm (+/-50.77 μm) measured with the OM and 83.37 μm (+/-44.38 μm) measured with the SEM, respectively. AMD mean values were 158.60 μm (+/-69.14 μm) for the OM and 152.72 μm (+/-72.36) for the SEM. Copings manufactured after digital impression with Lava™ C.O.S. show comparable marginal parameters with the copings manufactured after conventional impression with polyvinyl syloxane. The mean MG values of both groups fit in the clinically acceptable range.

Granisetron is a selective 5-hydroxy tryptamine3 receptor antagonist and widely used for chemotherapy-induced nausea and vomiting (CINV). Recommended dose of intravenous granisetron in the USA and Europe has been set at 0.01 mg/kg (1 mg/body) in the antiemetic treatment guidelines established by the American Society of Clinical Oncology and National Comprehension Cancer Network. In contrast, the approved dose in Japan is 0.04 mg/kg (3 mg/body). Randomized controlled trials (RCTs) which compared 1 mg/body with 3 mg/body of intravenous granisetron for CINV had been reported in Japan. In these RCTs, however, hematological malignancy patients were excluded. We performed observational retrospective study to compare 1 mg/body with 3 mg/body of intravenous granisetron for the prevention of CINV and adverse events in hematological malignancy patients. Number of the patients and chemotherapy courses were 15 and 30 in the 1 mg/body group, and 15 and 27 in the 3 mg/body group, respectively. No nausea rates in the 1 and 3 mg/body group were 83% and 89% of courses, respectively. No vomiting rates in the 1 and 3 mg/body group were 97% and 100% of courses, respectively. The incidences of constipation in the 1 and 3 mg/body group were 34% and 45% of courses, respectively. Anaphylaxis and headache did not occur in both groups. Our findings suggested that 1 mg/body of intravenous granisetron can prevent from CINV in hematological malignancy patients, as well as 3 mg/body.

Objective: The aim of this study was to investigate the effect of adding risperidone to the general behavioral treatment of masturbation in children 3-7 years old. Methods: A 4 week randomized clinical controlled trial was designed in year 2009. Samples have been chosen from children who have been referred to the Child and Adolescence Psychiatric Clinic of Isfahan University of Medical Sciences. Ninety children were recruited at the study and randomly allocated into the risperidone and control groups (44 and 46 respectively). The risperidone group was medicated simultaneously by behavioral treatments and 0.25-1 mg of risperidone daily while the controls only received the behavioral treatments. Findings: The mean ± SD age of the risperidone and control groups was 5.3 ± 1.1 and 4.9 ± 1.1 years, respectively. The mean ± SD of the period of suffering from masturbation was 3.4 ± 1.2 and 3.8 ± 1.7 months in the risperidone and the control groups, respectively. At the beginning of the study, the mean frequency of masturbation in control and the risperidone groups was 2.6 ± 0.9 and 2.7 ± 0.9 times/day, whereas after the 4th week, it decreased to 1.4 ± 0.6 and 1.1 ± 0.5 times/day, respectively. The results showed a more reduction in the mean frequency of masturbation in the risperidone group significantly. Conclusion: In comparison to the general behavioral treatment, risperidone in addition to the behavioral treatment will probably reduce the frequency of masturbation in children more effectively.

Background Few studies have examined the very long-term outcomes after implantation of drug-eluting stents (DES) coated with biodegradable polymers (BP). This report presents the 5-year clinical follow-up of patients treated with BP-DES in the randomized PAINT trial. Methods The PAINT study is a prospective, multicenter randomized controlled trial that allocated 274 patients for treatment with two BP-DES formulations [paclitaxel-eluting stents (PES) or sirolimus-eluting stents (SES)] or bare metal stents (BMS) in a 1:2:2 ratio, respectively. The primary end-point of this sub-study was defined as the composite of the major cardiac adverse events (MACE) cardiac death, myocardial infarction (MI) or ischemia-driven target vessel revascularization (TVR) at 5 years. Results The 5-year MACE rates were different among the groups: 35.3%, 22.5% and 16.9% for BMS, PES and SES, respectively (P<0.05 for both DES vs. bare stent comparisons). The primary end-point was mainly driven by TVR: 31.8%, 14.1% and 12.2% for bare stents, PES and SES, respectively (P<0.05 for both DES vs. bare stent comparisons). The incidence of stent thrombosis (ST) was null for BMS during the entire follow-up. There was no definite or probable ST in the SES group after the second year, while one patient (1.0%) presented with a definite ST episode in the PES group between 4 and 5 years. Conclusions The tested biodegradable-polymer coated stents releasing either paclitaxel or sirolimus, compared with same bare metal platform, sustained their effectiveness in reducing combined major adverse cardiac events and re-intervention without an increase in ST during 5 years of follow-up.

Purpose: To compare the accuracy and complication rate of two different CT-guided transthoracic needle biopsy techniques: fine needle aspiration and an automated biopsy device.Methods: Two consecutive series of respectively 125 (group A) and 98 (group B) biopsies performed using 20-22 gauge coaxial fine needle aspiration (group A) and an automated 19.5 gauge coaxial biopsy device (group B) were compared in terms of their accuracy and complication rate.Results: Groups A and B included respectively 100 (80%) and 77 (79%) malignant lesions and 25 (20%) and 18 (21%) benign lesions. No significant difference was found between the two series concerning patients, lesions,more » and procedural variables. For a diagnosis of malignancy, a statistically significant difference in sensitivity was found (82.7% vs 97.4%) between results obtained with the automated biopsy device and fine needle aspiration respectively. For a diagnosis of malignancy, the false negative rate of the biopsy result was significantly higher (p <0.005) in group A (17%) than in group B (2.6%). For a specific diagnosis of benignity, no statistically significant difference was found between the two groups (44% vs 26%) but the automated biopsy device provided fewer indeterminate cases. There was no difference between the two groups concerning the pneumothorax rate, which was 20% in group A and 15% in group B, or the hemoptysis rate, which was 2.4% in group A and 4% in group B.Conclusion: For a diagnosis of malignancy when a cytopathologist is not available on-site, automated biopsy devices provide a lower rate of false negative results and a similar complication rate to fine needle aspiration.« less

A number of Dutch medical journals recently carried an advertisement stating that clopidogrel treatment reduced the number of ischaemic complications with 26%, compared with aspirin treatment. This is a miscalculation: the actual reduction is 0.51% in absolute rates, and 8.7% in relative terms. The error by Sanofi-Synthelabo arose by comparison of the event rates for clopidogrel (5.32%) as well as for aspirin (5.83%) with that in an imaginary placebo group (7.77%), yielding a reduction of ischaemic complications of 2.45% and 1.94% respectively; erroneous comparison of these two numbers leads to a difference of 26%.

This study aims to explore the effect of catnip Nepeta cataria (CNC) charcoal on the pharmacokinetics of the main alkaloids of Rhizoma Coptidis in vivo. Twenty-four rabbits were randomly divided into four groups and given oral administration of an aqueous extract of Rhizoma Coptidis (RCAE), RCAE plus CNC, RCAE plus activated carbon (AC), or distilled water, respectively. Plasma samples were collected after administration. The concentrations of berberine, coptisine, palmatine, and epiberberine in plasma were measured by high-performance liquid chromatography (HPLC). The pharmacokinetics data were calculated using pharmacokinetic DAS 2.0 software. The results showed that the area under the concentration-time curve (AUC) of berberine increased, while the AUC of coptisine, palmatine, and epiberberine decreased in the rabbits that received RCAE plus CNC. Meanwhile, the AUC of berberine, coptisine, palmatine, and epiberberine decreased in the group given RCAE plus AC. The difference of main pharmacokinetics parameters among the four groups was significant (P < 0.05). This study showed that CNC improved the bioavailability of berberine in comparison to AC and prolonged its release in comparison to RCAE alone. However, it decreased the bioavailability of coptisine, palmatine, and epiberberine. In comparison, AC uniformly declined the bioavailability of berberine, coptisine, palmatine, and epiberberine.

[Purpose] The purpose of this study was to compare the effect of Schroth and Pilates exercises on the Cobb angle and body weight distribution of patients with idiopathic scoliosis. [Subjects] Twenty-four scoliosis patients with a Cobb angle of ≥20° were divided into the Schroth exercise group (SEG, n = 12) and the Pilates exercise group (PEG, n = 12). [Methods] The SEG and PEG performed Schroth and Pilates exercises, respectively, three times a week for 12 weeks. The Cobb angle was measured in the standing position with a radiography apparatus, and weight load was measured with Gait View Pro 1.0. [Results] In the intragroup comparison, both groups showed significant changes in the Cobb angle. For weight distribution, the SEG showed significant differences in the total weight between the concave and convex sides, but the PEG did not show significant differences. Furthermore, in the intragroup comparison, the SEG showed significant differences in the changes in the Cobb angle and weight distribution compared with the PEG. [Conclusion] Both Schroth and Pilates exercises were effective in changing the Cobb angle and weight distribution of scoliosis patients; however, the intergroup comparison showed that the Schroth exercise was more effective than the Pilates exercise.

Both dasatinib and nilotinib are approved frontline therapy for chronic myeloid leukemia in chronic phase (CML-CP) based on randomized trials compared with imatinib. However, no head-to-head comparison of dasatinib and nilotinib has been conducted in patients with newly diagnosed CML-CP. The authors conducted a propensity score (PS) matched comparison of patients with CML-CP who received frontline therapy with either dasatinib (N = 102) or nilotinib (N = 104) under the respective phase 2 trials conducted in parallel. PS matching resulted in 87 patients from each trial being matched for pretreatment characteristics. The 3-month BCR-ABL1/ABL1 ratio <10% rate was 93% with dasatinib and 94% with nilotinib (P = .25); the rates of major molecular response at 12 months were 77% and 85%, respectively (P = .13); and the rates of molecular response with 4.5-log reduction in the ratio at 36 months were 66% and 64%, respectively (P = .96). All other clinically relevant responses were similar between the 2 treatment cohorts. The 3-year probability of event-free survival was 89% among the patients who received dasatinib and 87% among those who received nilotinib (P = .99), and the corresponding 3-year overall survival probabilities were 99% and 93%, respectively (P = .95). No statistical difference was observed between the dasatinib and nilotinib groups in any of the other survival endpoints. The treatment discontinuation rate also was similar between the 2 cohorts (dasatinib group, 18%; nilotinib group, 19%; P = .82). In a PS-matched cohort of patients with newly diagnosed CML-CP, dasatinib and nilotinib offer similar response and survival outcomes. Both drugs can be considered reasonable standard-of-care options as first-line therapy for patients with CML-CP.

To compare flap morphology created by the WaveLight FS200 femtosecond laser and the VisuMax femtosecond laser, assessing the uniformity, accuracy, and predictability of flap creation. A total of 400 eyes had corneal flaps created with the WaveLight FS200 femtosecond laser (200 eyes) or the VisuMax femtosecond laser (200 eyes). The desired flap thickness was 110 μm. At 1 week postoperatively, all eyes were evaluated with RTVue Fourier-domain optical coherence tomography. Dimensions of the flaps were tested for their regularity, uniformity, accuracy, and predictability comparison. One week after surgery, the central flap thickness and the mean flap thickness of the FS200 group were 105.4 ± 3.4 μm and 105.7 ± 2.6 μm, respectively. They were both thinner than those of the VisuMax group, which were 110.8 ± 3.9 μm and 111.3 ± 2.3 μm, respectively. The mean deviation between the achieved and attempted flap thickness of the FS200 group (5.2 ± 1.9 μm) was greater than that of the VisuMax group (3.2 ± 1.8 μm). Flap thickness measurements at 36 points in both groups were close to the intended thickness. Morphology of the flaps in the 0-, 45-, 90-, and 135-degree lines created by the FS200 femtosecond laser and VisuMax femtosecond laser were uniform and regular. Flap dimensions created by the WaveLight FS200 femtosecond laser and VisuMax femtosecond laser were uniform and regular. Although the flap thickness created by the FS200 was less than that created by the VisuMax, measurements of both femtosecond lasers were close to the intended thickness.

Introduction With increased trend among people to choose a healthy diet, there is an increased consumption of health drinks by children. Thus, it is important to know their cariogenicity. Aim To evaluate the effect of consumption of health drinks viz., Horlicks, Boost and Complan on plaque pH in children. Materials and Methods The study consisted of four groups: Group I (control)- 10% sucrose solution, Group II- Horlicks, Group III- Boost, Group IV- Complan. Samples of plaque from representative teeth were collected and pH was measured using an electrode outside the mouth. After baseline pH was recorded, children were given their respective drinks and were asked to consume slowly over a period of three to five minutes following swish with 20 ml of the test drink for one minute. The pH was then recorded after 10, 20, 30, 40 and 60 minutes of the post consumption period. Obtained values were subjected to one-way ANOVA test for multiple group comparison followed by Post-Hoc Tukey’s test for group wise comparison. Results Twenty minutes after consumption of Complan and Boost, pH was decreased, but not to the critical pH value as in case of sucrose. The pH was found to be slightly increased, 20 minutes post Horlicks consumption. Post 60 minutes consumption of all the drinks including sucrose solution, the pH was increased in comparison to post 20 minutes. However, 60 minutes post consumption of Boost and Horlicks, pH increased above the baseline. Conclusion Consumption of health drinks viz., Complan and Boost did not lower the plaque pH to the level of critical pH. Consumption of Horlicks increased the plaque pH. PMID:28658897

Psychosocial factors have been linked with loss to follow-up (LTFU) and clinical outcomes among people living with HIV (PLH), however little is known about the effect of psychosocial support on LTFU among PLH in treatment and care. The purpose of this study was to explore the effect of NAMWEZA ("Yes, together we can") friends' psychosocial support intervention on clinical outcomes and LTFU among PLH. NAMWEZA is based on a novel program using "appreciative inquiry", positive psychology approaches to empower, promote positive attitudes and foster hope. PLH participating in the NAMWEZA intervention in HIV care clinics in Dar es Salaam Tanzania were compared with non-exposed PLH obtained from facilities that routinely collect clinical information and both followed longitudinally for 24 months. Baseline sociodemographic, clinical measures (CD4 cell count, hemoglobin (HGB), weight), and LTFU measures were collected. Chi square, Fisher's exact tests, and t-tests were used to compare the frequencies for categorical variables and the means of continuous variables from the intervention and the comparison groups to identify variables that were significantly different across the two groups. Random effects models were performed to examine the bivariate associations between the intervention status and clinical outcomes. At the end of 24 months of follow-up mean CD4 count and HGB levels increased significantly in both intervention and comparison groups (p = 0.009 and p < 0.0001, respectively). Weight increased significantly only in the intervention group (p = 0.003). Cumulative LTFU was three times higher in the comparison compared to the intervention (p < 0.001) group. Having a low CD4 count, extremes of weight, low HGB, younger age, and male gender were significantly associated with LTFU among the unexposed group, while being on ART for duration of 12 months or more was protective against LTFU in those intervened. Among PLH on ART, exposed or not exposed to NAMWEZA intervention, clinical care outcomes improved over time. LTFU was much higher in the comparison group with factors commonly known to predict LTFU only apparent in the comparison group. NAMWEZA could be a promising peer-facilitated model to reduce LTFU among PLH in care that can be integrated in ART services; however, more research is needed to evaluate its longer term effects.

While the United States and Slovakia offer different healthcare delivery systems, each country faces the same challenges of improving the health status of their populations. The authors explore the impact of their respective systems on the health of their populations and compare the health outcomes of both nations. They point out that socioeconomic factors play a far more important role in determining population health outcomes than do the structures of the systems surrounding the care delivery. The authors illustrate this finding through a comparison of the poverty and education levels of a selected minority group from each country in relation to the health outcomes for each population group. The comparison reveals that education is a more influential determinant in a population's health outcomes, than the improved access to care offered by a universal system.

Progress report of the IAU Commission 4 Working Group on Ephemeris Access and the comparison of high accuracy planetary ephemerides

NASA Astrophysics Data System (ADS)

Hilton, J. L.

2012-12-01

In September 2010 IAU Commission 4, Ephemerides, organized a working group to provide a recommendation for a preferred format for solar system ephemerides. The purpose of this recommendation is to provide easy access to a wide range of solar system ephemerides for users. The working group, chaired by Hilton, includes representatives from each of the major planetary ephemeris groups and representatives from the satellite and asteroid ephemeris communities. The working group has tentatively decided to recommend the SPK format developed by the Jet Propulsion Laboratory's Navigation and Ancillary Information Facility for use with its SPICE Toolkit. Certain details, however, must still be resolved before a final recommendation is made by the working group. An update is also provided to ongoing analysis comparing the three high accuracy planetary ephemerides, DE421, EPM2008, and INPOP10a. The principal topics of this update are: replacing the INPOP08 ephemeris with the INPOP10a ephemeris, making the comparisons with respect to DE421 rather than DE405, and comparing the TT - TDB values determined in EPM2008 and INPOP10a with the Fairhead & Bretagnon (1990, A&A, 229, 240) model used in DE421 as T_eph.

Age-related invariance of abilities measured with the Wechsler Adult Intelligence Scale-IV.

Assessment of measurement invariance across populations is essential for meaningful comparison of test scores, and is especially relevant where repeated measurements are required for educational assessment or clinical diagnosis. Establishing measurement invariance legitimizes the assumption that test scores reflect the same psychological trait in different populations or across different occasions. Examination of Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) U.S. standardization samples revealed that a first-order 5-factor measurement model was best fitting across 9 age groups from 16 years to 69 years. Strong metric invariance was found for 3 of 5 factors and partial intercept invariance for the remaining 2. Pairwise comparisons of adjacent age groups supported the inference that cognitive-trait group differences are manifested by group differences in the test scores. In educational and clinical settings these findings provide theoretical and empirical support to interpret changes in the index or subtest scores as reflecting changes in the corresponding cognitive abilities. Further, where clinically relevant, the subtest score composites can be used to compare changes in respective cognitive abilities. The model was supported in the Canadian standardization data with pooled age groups but the sample sizes were not adequate for detailed examination of separate age groups in the Canadian sample.

The aim of this study was to analyze differences in symptom burden, baseline and outcome parameters, including completion of palliative radiotherapy and 30-day mortality, between patients treated with palliative radiotherapy (RT) who were managed exclusively by regular oncology staff or a multidisciplinary palliative care team (MPCT) in addition. This was a retrospective single-institution analysis. Comparison of two groups of patients: MPCT versus none (n=36 and 65, respectively). All patients provided Edmonton symptom assessment system (ESAS) data before RT. The MPCT group included significantly more patients with reduced performance status. Furthermore, these patients had higher ESAS symptom scores, except for two items (dyspnea, sleep). The largest differences were observed for pain, fatigue, anxiety and depression. The significant difference in pain scores was also reflected in different opioid medication rates. Failure to complete radiotherapy was more common in the MPCT group (11 and 2%, respectively, p=0.05). Thirty-day mortality was different, too (28 and 2%, respectively, p=0.0001). The Kaplan-Meier survival curves were not significantly different (1-year survival rates 21 and 25%, respectively, p=0.27). The MPCT group was characterized by a higher symptom burden. Prognostic factors such as performance status were not balanced between the two groups. Despite this fact, actuarial overall survival was comparable. Given the high rate of 30-day mortality in the MPCT group, efforts to optimize criteria for initiation of radiotherapy are warranted.

There is still controversy as to the efficacy of light activation used in tooth whitening. The purpose of this study was to evaluate the effect of light activation on tooth color change relative to the artificial dye color. Extracted human third molars (160) were randomly distributed into eight groups of 20 specimens each based on artificial staining and use of light activation. All groups received three 45-minute sessions of in-office whitening at 3-day intervals. Color measurements were performed with an intraoral spectrophotometer at baseline prior to staining (T0), after artificial staining (T1), 1-day--(T2), and 1-week--(T3) post-whitening. Color differences were calculated relative to after artificial staining color parameters (L*1, a*1, b*1) with the use of a software analysis program enabling synchronization of two images. Within the same staining groups, the light-activated samples exhibited a greater color change than their nonlight-activated counterparts. However, only in the case of the yellow-stained samples at 1-day post-whitening was there a significant difference between the nonlight-activated and light-activated groups (Tukey's post hoc multiple comparison test for pairwise comparisons, p < 0.05). Light activation is a valid method for enhancing the efficacy of tooth whitening with respect to overall color change and works best with yellow stains. Light activation is a valid method for enhancing the efficacy of tooth whitening with respect to overall color change and works best with yellow stains.

This study reports simultaneous repair of soft-tissue loss and proper digital nerve defect in the finger using a boomerang nerve flap including nerve graft from the dorsal branch of the proper digital nerve. From July of 2007 to May of 2010, the flap was used in 17 fingers in 17 patients. The injured fingers included five index, seven long, and five ring fingers. The mean soft-tissue loss was 2.5 × 1.9 cm. The mean flap size was 2.8 × 2.1 cm. Proper digital nerve defects were reconstructed using nerve graft harvested from the dorsal branch of the adjacent finger's proper digital nerve. The average nerve graft length was 2.5 cm. The comparison group included 32 patients treated using a cross-finger flap and a secondary free nerve graft. In the study group, 15 flaps survived completely. Partial necrosis at the distal edge of the flap occurred in two cases. At a mean follow-up of 22 months, the average static two-point discrimination and Semmes-Weinstein monofilament test results on the pulp of the reconstructed finger were 7.5 mm and 3.86, respectively. In the comparison group, the results were 9.3 mm and 3.91, respectively. The study group presented better discriminatory sensation on the pulp and milder pain and cold intolerance in the reconstructed finger. The boomerang nerve flap is useful and reliable for reconstructing complicated finger damage involving soft-tissue loss and nerve defect, especially in difficult anatomical regions. Therapeutic, II.

To compare the validity and safety between holmium: YAG laser and traditional surgery in partial nephrectomy. A total of 28 patients were divided into two groups (holmium: YAG laser group without renal artery clamping and traditional surgery group with renal artery clamping). The intraoperative blood loss, total operative time, renal artery clamping time, postoperative hospital stay, separated renal function, postoperative complications and depth of tissue injury were recorded. The intraoperative blood loss, total operative time, renal artery clamping time, postoperative hospital stay, separated renal function, postoperative complications and depth of tissue injury were 80 ml, 77 min, 0 min, 7.4 days, 35 ml/min, 0, 0.9 cm, respectively, in holmium: YAG laser group. And in traditional surgery group were 69 ml, 111 min, 25.5 min, 7.3 days, 34 ml/min, 0, 2.0 cm, respectively. The differences of total operative time, renal artery clamping time and depth of tissue injury between two groups were statistically significant. The others were not statistically significant. Holmium: YAG laser is effective and safe in partial nephrectomy. It can decrease the total operative time, minimize the warm ischemia time and enlarge the extent of surgical excision.

Background: Aloe Vera is one of the endemic plants in southern Iran, which has been mentioned in the textbooks of Persian medicine since 2500 years ago. The aim of this study was to compare the effectiveness and cost of Aloe Vera gel with conventional treatments in patients with chronic ulcers. Methods: This comparative study was conducted on 60 patients with chronic ulcers (more than 3 weeks) in Al-Zahra hospital (Isfahan, Iran) in 2015. The participants were divided into two groups of 30 patients per group. In one group, we used conventional treatment plus Aloe Vera gel and in the other group, only the conventional treatment was used. In the Aloe Vera group, we used Aloe Vera gel twice a day. The patients were followed-up a week after the treatment and then monthly for 3 months. Results: The male: female ratio was 1:1 in each group. The mean age of the Aloe Vera and control groups were 62.3±11.2 and 63.1±9.6, respectively. After three months follow-up, wound healing occurred in 28 (93.3%) patients in the Aloe Vera group and 14 (46.7%) patients in the control group (P<0.05). The overall mean time of wound healing was 31.25±11.2 and 63.2±20.4 in the Aloe Vera and control groups, respectively (P<0.05). The mean hospitalization time was 35.2±6.4 and 67.4±8.9 in the Aloe Vera and control groups, respectively (P<0.05). The average cost of Aloe Vera gel and conventional treatment per patient was $2 and $10 daily, respectively (P<0.05). Conclusion: Aloe Vera gel is a beneficial treatment and cost effective for patients with chronic ulcers. The use of Aloe Vera gel in chronic ulcer is recommended in developing countries to lessen the financial burden. PMID:27840496

To compare effective phacoemulsification time (EPT) for the removal of brunescent cataracts treated with femtosecond laser-assisted cataract surgery with standard cataract phacoemulsification techniques. Ruhr University Eye Hospital, Bochum, Germany. Comparative prospective case study. The Lens Opacities Classification System III (LOCS III) grading system was used to measure eyes divided into 4 groups having cataract surgery. Groups 1 and 2 contained eyes with LOCS III grade nuclear opalescence (NO) 3 cataracts treated with standard cataract surgery and femtosecond laser-assisted cataract surgery, respectively. Groups 3 and 4 contained brunescent cataracts, LOCS III grades NO5, treated with standard cataract surgery and femtosecond laser-assisted cataract surgery, respectively. There were 240 eyes, with 60 eyes in each group. The EPT in Group 1 ranged from 0.46 to 3.10 (mean 1.38); the EPT in all eyes in Group 2 was 0 (P < .001). The EPT in Groups 3 and 4 was 2.12 to 19.29 (mean 6.85) and 0 to 6.75 (mean 1.35), respectively (P < .001). A comparison between EPT in Groups 1 and 4 showed that EPT in Group 4 was also lower than in Group 1 (P = .013). Groups 4 and 1 were the most statistically similar of all groups compared, suggesting that EPT for a femtosecond laser-treated grade 5 cataract was most similar to that of a standard-treated grade 3 cataract. Femtosecond laser pretreatment for brunescent cataracts allowed for a significant reduction in EPT compared with manual standard phacoemulsification techniques. Drs.

Lay navigators in the Patient Care Connect Program support patients with cancer from diagnosis through survivorship to end of life. They empower patients to engage in their health care and navigate them through the increasingly complex health care system. Navigation programs can improve access to care, enhance coordination of care, and overcome barriers to timely, high-quality health care. However, few data exist regarding the financial implications of implementing a lay navigation program. To examine the influence of lay navigation on health care spending and resource use among geriatric patients with cancer within The University of Alabama at Birmingham Health System Cancer Community Network. This observational study from January 1, 2012, through December 31, 2015, used propensity score-matched regression analysis to compare quarterly changes in the mean total Medicare costs and resource use between navigated patients and nonnavigated, matched comparison patients. The setting was The University of Alabama at Birmingham Health System Cancer Community Network, which includes 2 academic and 10 community cancer centers across Alabama, Georgia, Florida, Mississippi, and Tennessee. Participants were Medicare beneficiaries with cancer who received care at participating institutions from 2012 through 2015. The primary exposure was contact with a patient navigator. Navigated patients were matched to nonnavigated patients on age, race, sex, cancer acuity (high vs low), comorbidity score, and preenrollment characteristics (costs, emergency department visits, hospitalizations, intensive care unit admissions, and chemotherapy in the preenrollment quarter). Total costs to Medicare, components of cost, and resource use (emergency department visits, hospitalizations, and intensive care unit admissions). In total, 12 428 patients (mean (SD) age at cancer diagnosis, 75 (7) years; 52.0% female) were propensity score matched, including 6214 patients in the navigated group and 6214 patients in the matched nonnavigated comparison group. Compared with the matched comparison group, the mean total costs declined by $781.29 more per quarter per navigated patient (β = -781.29, SE = 45.77, P < .001), for an estimated $19 million decline per year across the network. Inpatient and outpatient costs had the largest between-group quarterly declines, at $294 and $275, respectively, per patient. Emergency department visits, hospitalizations, and intensive care unit admissions decreased by 6.0%, 7.9%, and 10.6%, respectively, per quarter in navigated patients compared with matched comparison patients (P < .001). Costs to Medicare and health care use from 2012 through 2015 declined significantly for navigated patients compared with matched comparison patients. Lay navigation programs should be expanded as health systems transition to value-based health care.

Although knee injuries in professional soccer (football) have been extensively studied, the prevalence of knee osteoarthritis (OA) in veteran players is not well documented. To investigate the prevalence of knee OA in retired professional soccer players in comparison with a group of athletically active military personnel. Cross-sectional study; Level of evidence, 3. A group of 100 veteran Greek soccer players aged 35 to 55 years (mean [±SD] age, 46.90 ± 5.9 years) were examined for knee OA and were administered the Knee injury and Osteoarthritis Outcome Score (KOOS) questionnaire. A matched group of 100 athletically active military personnel served as a comparison group. The sonographic prevalence of OA was significantly higher in the veteran soccer group (52%) than in the military group (33%) (n = 200; P = .010). This difference remained significant even after excluding participants with a history of knee surgery (44.1% vs 25.3%, respectively) (n = 151; P = .010). Femoral cartilage thickness was similar between the 2 groups (P = .473), while altered knee alignment had no effect on the prevalence of OA (P = .740). With the exception of perceived pain being more prevalent in the military group, there were no other statistically significant differences between the 2 groups in KOOS values. Veteran soccer players had a higher sonographic prevalence of knee OA but better pain scores than a matched group of athletically active military personnel. © 2016 The Author(s).

The Pacific oyster, Crassostrea gigas, has evolved sophisticated mechanisms to adapt the changing ambient conditions, and protect themselves from stress-induced injuries. In the present study, the expression profiles of mRNA transcripts in the haemocytes of oysters under heat stress were examined to reveal the possible mechanism of heat stress response. There were 23,315, 23,904, 23,123 and 23,672 transcripts identified in the haemocytes of oysters cultured at 25 °C for 0, 6, 12, and 24 h (designed as B, H6, H12, H24), respectively. And 22,330 differentially expressed transcripts (DTs) were yielded in the pairwise comparisons between the above four samples, which corresponded to 8074 genes. There were 9, 12 and 22 Gene Ontology (GO) terms identified in the DT pairwise comparison groups of H6_B, H12_H6 and H24_H12, respectively, and the richest GO terms in biological process category were cellular catabolic process, translational initiation and apoptotic process, respectively. There were 108, 102 and 102 KEGG pathways successfully retrieved from DTs comparison groups DTH6_B, DTH12_H6 and DTH24_H12, respectively, among which 93 pathways were shared by all three comparison groups, and most of them were related to metabolism of protein, carbohydrate and fat. The expression patterns of 12 representative heat stress response-relevant genes detected by quantitative real-time PCR (qRT-PCR) were similar to those obtained from transcriptome analysis. By flow cytometric analysis, the apoptosis rate of haemocytes increased significantly after oysters were treated at 25 °C for 24 h and recovered at 4 °C for 12 h (p < 0.05) and 36 h (p < 0.01), and it also increased significantly when the heat treatment lasted to 60 h (p < 0.01). The present results indicated that, when oysters encountered short term heat stress, the expression of genes related to energy metabolism, as well as unfolded protein response (UPR) and anti-apoptotic system, were firstly regulated to maintain basic life activities, and then a large number of genes involved in stabilizing protein conformation and facilitating further protein refolding were activated to repair the stress injury. However, the stress injury gradually became irreparable with the stress persisting, and apoptosis was activated when the heat treatment prolonged to 24 h. The information was useful to better understand the molecular mechanism of heat stress response and develop strategies for the improvement of oyster survival rate during summer high-temperature period.

Renal dysfunction is an independent predictor for cardiovascular morbidity and mortality. We investigated whether chronic hepatitis C virus (HCV) infection and the related insulin resistance/hyperinsulinemia influence renal function in comparison with a group of healthy subjects and with another group with metabolic syndrome. We enrolled 130 newly diagnosed HCV outpatients matched for age and gender with 130 patients with metabolic syndrome and 130 healthy subjects. Renal function was evaluated by calculation of glomerular filtration rate (e-GFR, mL/min/1.73 m(2)) using the CKD-EPI equation. The following laboratory parameters were measured: fasting plasma glucose and insulin, total, LDL- and HDL-cholesterol, triglyceride, creatinine, and HOMA to evaluate insulin sensitivity. HCV patients with respect to both healthy subjects and metabolic syndrome patients have a decreased e-GFR: 86.6 ± 16.1 vs 120.2 ± 23.1 mL/min/1.73 m(2) (P < 0.0001) and 94.9 ± 22.6 mL/min/1.73 m(2) (P = 0.003), respectively. Regarding biochemical variables, HCV patients, in comparison with healthy subjects, have a higher triglyceride level, creatinine, fasting insulin and HOMA (3.4 ± 1.4 vs 2.6 ± 1.3; P < 0.0001). At linear regression analysis, the correlation between e-GFR and HOMA is similar in the metabolic syndrome (r = -0.555, P < 0.0001) and HCV (r = -0.527, P < 0.0001) groups. At multiple regression analysis, HOMA is the major determinant of e-GFR in both groups, accounting for, respectively, 30.8 and 27.8 % of its variation in the metabolic syndrome and HCV. In conclusion, we demonstrate that HCV patients have a significant reduction of e-GFR and that insulin resistance is the major predictor of renal dysfunction.

Objective: To make a comparison between terbinafine 1% cream and ketoconazole 2% cream in the treatment of pityriasis versicolor. Methods: This randomized single blind study included 110 patients with clinical diagnosis of pityriasis versicolor and positive mycological test for Malassezia furfur. The patients were randomly assigned to two groups. Group 1 used terbinafine cream and group 2 applied ketoconazole cream on the skin lesions for two weeks. Each group consisted of 55 patients. Clinical and mycological examinations were performed at baseline, at the end of the 2nd, 4th and 8th week of starting the treatment regimens. Results: At the end of the 2nd week we achieved cure rates of 72% and 64.3% for group 1 and group 2 respectively. At the end of the 4th week the respective cure rates for group 1 and group 2 were 81.2% and 69%, and at the end of the 8th week 70.8% of the patients in group 1 and 61.9% of the patients in group 2 were cured. Conclusion: The results of this study showed no significant statistical differences between the two groups in regard to cure and recurrence rates. But the numbers of cured patients were higher and recurrent cases were lower in group 1. PMID:25674122

Background The ultrasound guidance in regional nerve blocks has recently been introduced and gaining popularity. Ultrasound-guided supraclavicular block has many advantages including the higher success rate, faster onset time, and fewer complications. The aim of this study was to examine the clinical data according to the varied volume of local anesthetics in the ultrasound-guided supraclavicular block. Methods One hundred twenty patients were randomized into four groups, according to the local anesthetic volume used: Group 35 (n = 30), Group 30 (n = 30), Group 25 (n = 30), and Group 20 (n = 30). Supraclavicular blocks were performed with 1% mepivacaine 35 ml, 30 ml, 25 ml, and 20 ml, respectively. The success rate, onset time, and complications were checked and evaluated. Results The success rate (66.7%) was lower in Group 20 than that of Group 35 (96.7%) (P < 0.05). The average onset times of Group 35, Group 30, Group 25, and Group 20 were 14.3 ± 6.9 min, 13.6 ± 4.5 min, 16.7 ± 4.6 min, and 16.5 ± 3.7 min, respectively. There were no significant differences. Horner's syndrome was higher in Group 35 (P < 0.05). Conclusions In conclusion, we achieved 90% success rate with 30 ml of 1% mepivacaine. Therefore, we suggest 30 ml of local anesthetic volume for ultrasound-guided supraclavicular block. PMID:23814648

Studies have shown that individuals with COPD have impaired body balance, probably caused by the disease's multisystemic manifestations plus age-related decline in balance, potentially increasing the risk of falling and its consequences. However, little is known about the profile of individuals with COPD who present balance impairments, especially related to sex and disease severity stages. The aim of this work was to compare static and functional balance between subjects with COPD and healthy controls and to check possible differences according to sex and degrees of disease severity. Forty-seven subjects with COPD and 25 healthy controls were included in this study. Their static balance was assessed in one-legged stance using a force platform and functional balance with the Timed Up and Go test. Additionally, participants performed spirometry, the 6-min walk test and isometric quadriceps maximal voluntary contraction assessment. Disease severity was classified according to the Global Initiative for Obstructive Lung Disease stages and BODE (body mass index, air-flow obstruction, dyspnea, and exercise capacity) scores. In comparison with healthy controls, subjects with COPD had worse static (center of pressure displacement area: 9.3 ± 1.9 cm 2 vs 11.6 ± 4.0 cm 2 , respectively, P = .01) and functional balance (Timed Up and Go test: 8.5 ± 1.3 s vs 10.3 ± 1.8 s, respectively, P < .001). In the COPD group, men performed better in the Timed Up and Go test than women (9.8 ± 1.2 s vs 10.9 ± 2.2 s, respectively, P = .03), whereas women presented a better static balance in comparison with men for all parameters related to center of pressure (P < .005 for all). Disease severity did not affect any balance results. Individuals with COPD had worse static and functional balance in comparison with healthy controls. Sex can mediate these results, depending on the type of balance evaluation (force platform or functional test). Balance performance was similar among the groups classified according to disease severity. Copyright © 2016 by Daedalus Enterprises.

Opportunity for natural selection among five population groups of Manipur in comparison with other North East Indian population has been studied. Crow's index as well as Johnston and Kensinger's index for natural selection were calculated based on differential fertility and mortality. The mortality component was found to be lower compared to fertility component in all the populations which may attribute to comparatively improved and easily accessible health care facilities. However, different selection pressures, artificial and natural, seem to be influencing the selection intensity through induced abortion and spontaneous abortion among the two non-tribal migrant groups: Bamon and Muslims, respectively. This study highlights the probable interaction of artificial and natural selection in determining the evolutionary fate of any population group.

This study evaluates the effects of a group intervention for women sexually abused in childhood or adulthood. The sample consisted of 41 women involved in a group intervention based on a feminist approach offered by help centers for sexual assault victims in Quebec and 11 women in a wait-list comparison group. Results reveal that the group intervention reduced psychological distress and consequences associated with sexual abuse and that gains were maintained at three-month follow- up. Analyses of potential factors related to differential gains indicated that abuse-related variables and concurrent individual interventions were not linked to outcomes. Exploratory analyses suggested that women experiencing severe physical partner violence showed greater gains with respect to self-blame/stigmatization, sexual anxiety, and anxiety related to assertiveness.

This study aimed to compare the pharmacokinetics of tramadol between young and middle-aged dogs. Tramadol (4 mg/kg) was administered intravenously (IV) to young and middle-aged dogs (2 and 8–10 years, respectively). Plasma concentrations of tramadol were measured using high-performance liquid chromatography (HPLC), and its pharmacokinetics best fit a two-compartment model. The volume of distribution (Vd), elimination half-life (t1/2,β) and total body clearance (CLtot) of the young group were 4.77 ± 1.07 l/kg, 1.91 ± 0.26 hr and 29.9 ± 7.3 ml/min/kg, respectively, while those of the middle-aged group were 4.73 ± 1.43 l/kg, 2.39 ± 0.97 hr and 23.7 ± 5.4 ml/min/kg, respectively. Intergroup differences in the t1/2,β and CLtot were significant (P<0.05). In conclusion, tramadol excretion was significantly prolonged in middle-aged dogs. PMID:26875837

Antibiotics are a front-line weapon against many infectious diseases. However, antibiotic overuse is the key driver of drug resistance. Previously published studies have suggested benefits of using peer-to-peer education, working with group leaders to build trust and maintain confidentiality within a quality initiative. We hypothesized that working with physicians as a peer group might be beneficial in influencing antibiotic prescribing patterns. To describe and evaluate a peer group model for an intervention to reduce the volume of antibiotic prescriptions among physicians with above average prescribing rates serving an Arab community in northern Israel. Primary care physicians in a defined geographic area who served Arab communities and had high antibiotic prescribing rates--defined as above average number of antibiotic prescriptions per office visit compared with regional and organizational averages--were recruited for the intervention. All other physicians from the same region served as a comparison group. The intervention was administered during 2007 and was completed in early 2008. Four structured meetings scheduled 2 months apart, in which the group explored the issues related to antibiotic overuse, included the following topics: adherence to clinical guidelines; the special position physicians serving Arab communities hold and the influence it has on their practices; pressure due to consumer demands; and suggestions for possible strategies to face ethnic sensitivity, mainly because of the special ties the physicians have with their communities. T-tests for independent samples were used to perform between-group comparisons for each quarter and year of observation from 2006 through 2010, and t-tests for paired samples were used to compare pre-intervention with post-intervention antibiotic prescribing rates. In the 2006 pre-intervention period, the antibiotic prescribing rates were 0.17 for the peer group (n = 11 physicians) and 0.15 for the comparison group (n = 72 physicians, P = 0.279). In 2008 following the intervention, rates were 0.12 and 0.14, respectively (P = 0.396). In the paired t-test analysis, rates declined significantly from 2006 to 2008 in the intervention group (P < 0.001) but not in the comparison group (P = 0.138). Antibiotic prescribing rates remained similar in 2009 and 2010. In the context of a community with special ethnic and cultural characteristics, an intervention relying on peer group techniques was associated with a modest reduction in the volume of antibiotic prescriptions.

Purpose To compare surgical outcomes and complications after percutaneous nephrolithotomy (PCNL) under regional or general anesthesia. Materials and Methods One hundred and one patients who underwent PCNL as a first-line treatment for kidney calculi between June 2004 and June 2013 were enrolled in this retrospective study. Patients were classified into two groups by anesthetic method: 77 were allocated to the regional anesthesia group and 24 to the general anesthesia group. Patient general characteristics, stone features, surgical outcomes, and complications were compared between the two groups. Results The two groups were similar in terms of mean age and stone size, number, and type. Furthermore, they did not differ significantly in terms of general characteristics, treatment outcomes, or complications excluding postoperative fever. However, mean hospital stay was significantly shorter in the regional anesthesia group than in the general anesthesia group (8.9±3.2 days vs. 11.5±6.9 days, respectively, p=0.025). Also, the postoperative fever rate was significantly higher in the general anesthesia group (53.2% vs. 83.3%, respectively, p=0.007). Conclusions Regional anesthesia is as effective as general anesthesia during percutaneous nephrolithotomy and is associated with shorter hospital stays and lower rates of postoperative fever.

This study was conducted to: (i) analyse whether students admitted to one medical school based on top pre-university grades, a voluntary multifaceted selection process, or lottery, respectively, differed in study performance; (ii) examine whether students who were accepted in the multifaceted selection process outperformed their rejected peers, and (iii) analyse whether participation in the multifaceted selection procedure was related to performance. We examined knowledge test and professionalism scores, study progress and dropout in three cohorts of medical students admitted to the University of Groningen, the Netherlands in 2009, 2010 and 2011 (n = 1055). We divided the lottery-admitted group into, respectively, students who had not participated and students who had been rejected in the multifaceted selection process. We used ancova modelling, logistic regression and Bonferroni post hoc multiple-comparison tests and controlled for gender and cohort. The top pre-university grade group achieved higher knowledge test scores and more Year 1 course credits than all other groups (p < 0.05). This group received the highest possible professionalism score more often than the lottery-admitted group that had not participated in the multifaceted selection process (p < 0.05). The group of students accepted in the multifaceted selection process obtained higher written test scores than the lottery-admitted group that had not participated (p < 0.05) and achieved the highest possible professionalism score more often than both lottery-admitted groups. The lottery-admitted group that had not participated in the multifaceted selection process earned fewer Year 1 and 2 course credits than all other groups (p < 0.05). Dropout rates differed among the groups (p < 0.05), but correction for multiple comparisons rendered all pairwise differences non-significant. A top pre-university grade point average was the best predictor of performance. For so-called non-academic performance, the multifaceted selection process was efficient in identifying applicants with suitable skills. Participation in the multifaceted selection procedure seems to be predictive of higher performance. Further research is needed to assess whether our results are generalisable to other medical schools. © 2014 John Wiley & Sons Ltd.

A critical shortage of human resources for health in Zambia remains a great challenge. In response, the Zambian Ministry of Health developed a national community health assistant (CHA) programme, aiming to create a well-trained and motivated community-based health workforce. This study assessed whether CHAs increased treatment rates for diarrhoea, confirmed malaria or pneumonia in the first programme year. This study used a quasi-experimental difference-in-difference design, comparing changes in the catchment areas of health posts with CHAs to those without. Baseline and end line household surveys were conducted to measure the proportion of children under 5 years treated for diarrhoea, malaria or pneumonia in the 2 weeks before the survey and immunisation rates and malaria rapid diagnostic test rates. We surveyed 2330 women with children under five from the intervention area and 2314 from comparison areas at baseline and end line. Treatment for diarrhoea, malaria or pneumonia increased by 18.0% (P < 0.01) and 23.5% (P < 0.01) in the intervention and comparison groups, respectively, but DID analysis was not significant (P = 0.27). The proportion of fully immunised children grew by 7.5% in the intervention, but shrank by 7.5% in the comparison group (DID: 0.14; 95% CI 0.12-0.16, P < 0.01). Although we observed no significant difference between the intervention and comparison groups in the DID estimates for the primary outcome, there were significant increases after one year in treatment for all three diseases in the intervention group from baseline to end line and in the proportion of fully immunised children. © 2016 John Wiley & Sons Ltd.

The apolipoprotein E (APOE) genotype provides information on the risk of Alzheimer's disease, but the genotyping of patients and their family members has been discouraged. We examined the effect of genotype disclosure in a prospective, randomized, controlled trial. We randomly assigned 162 asymptomatic adults who had a parent with Alzheimer's disease to receive the results of their own APOE genotyping (disclosure group) or not to receive such results (nondisclosure group). We measured symptoms of anxiety, depression, and test-related distress 6 weeks, 6 months, and 1 year after disclosure or nondisclosure. There were no significant differences between the two groups in changes in time-averaged measures of anxiety (4.5 in the disclosure group and 4.4 in the nondisclosure group, P=0.84), depression (8.8 and 8.7, respectively; P=0.98), or test-related distress (6.9 and 7.5, respectively; P=0.61). Secondary comparisons between the nondisclosure group and a disclosure subgroup of subjects carrying the APOE epsilon4 allele (which is associated with increased risk) also revealed no significant differences. However, the epsilon4-negative subgroup had a significantly lower level of test-related distress than did the epsilon4-positive subgroup (P=0.01). Subjects with clinically meaningful changes in psychological outcomes were distributed evenly among the nondisclosure group and the epsilon4-positive and epsilon4-negative subgroups. Baseline scores for anxiety and depression were strongly associated with post-disclosure scores of these measures (P<0.001 for both comparisons). The disclosure of APOE genotyping results to adult children of patients with Alzheimer's disease did not result in significant short-term psychological risks. Test-related distress was reduced among those who learned that they were APOE epsilon4-negative. Persons with high levels of emotional distress before undergoing genetic testing were more likely to have emotional difficulties after disclosure.

Left atrial (LA) scarring, a consequence of cardiac fibrosis is a powerful predictor of procedure-outcome in atrial fibrillation (AF) patients undergoing catheter ablation. We sought to compare the long-term outcome in patients with paroxysmal AF (PAF) and severe LA scarring identified by 3D mapping, undergoing pulmonary vein isolation (PVAI) only or PVAI and the entire scar areas (scar homogenization) or PVAI+ ablation of the non-PV triggers. Totally, 177 consecutive patients with PAF and severe LA scarring were included. Patients underwent PVAI only (n = 45, Group 1), PVAI+ scar homogenization (n = 66, Group 2) or PVAI+ ablation of non-PV triggers (n = 66, Group 3) based on operator's choice. Baseline characteristics were similar across the groups. After first procedure, all patients were followed-up for a minimum of 2 years. The success rate at the end of the follow-up was 18% (8 pts), 21% (14 pts), and 61% (40 pts) in Groups 1, 2, and 3, respectively. Cumulative probability of AF-free survival was significantly higher in Group 3 (overall log-rank P <0.01, pairwise comparison 1 vs. 3 and 2 vs. 3 P < 0.01). During repeat procedures, non-PV triggers were ablated in all. After average 1.5 procedures, the success rates were 28 (62%), 41 (62%), and 56 (85%) in Groups 1, 2, and 3, respectively (log-rank P< 0.001). In patients with PAF and severe LA scarring, PVAI+ ablation of non-PV triggers is associated with significantly better long-term outcome than PVAI alone or PVAI+ scar homogenization.

To evaluate the effect of varying cellulose casting ring liner length and its prewetting on the marginal adaptation and dimensional accuracy of full veneer metal castings. The master die was milled in stainless steel to fabricate the wax pattern. Sixty wax patterns were fabricated with a uniform thickness of 1.5 mm at an occlusal surface and 1 mm axial surface, cervical width at 13.5 mm, and 10 mm cuspal height. The samples were divided into six groups ( n = 10). Groups I and II samples had the full-length cellulose prewet and dry ring liner, respectively. The groups III and IV had 2 mm short prewet and dry cellulose ring liner, respectively, whereas groups V and VI were invested in 6 mm short ring liner. The wax patterns were immediately invested in phosphate bonded investment, and casting procedure was completed with nickel-chrome alloy. The castings were cleaned and mean score of measurements at four reference points for marginal adaption, casting height, and cervical width was calculated. The marginal adaption was calculated with Imaje J software, whereas the casting height and cervical width was determined using a digital scale. The data was subjected to one-way analysis of varaince and Tukey post hoc statistical analysis with Statistical Package for the Social Sciences version 20 software. The group II had the best marginal adaption with a gap of 63.786 μm followed by group I (65.185 μm), group IV (87.740 μm), and group III (101.455 μm). A large marginal gap was observed in group V at 188.871 μm. Cuspal height was more accurate with group V (10.428 mm), group VI (10.421 mm), and group II (10.488 mm). The cervical width was approximately similar in group I, group III, and group V. Statistically significant difference was observed in Tukey post hoc analysis between group V and group VI with all the other groups with regards to marginal adaptation. The dry cellulose ring liners provided better marginal adaptation in comparison to prewet cellulose ring liners. Accurate cuspal height was obtained with shorter ring liner in comparison to full-length cellulose ring liners.

We retrospectively investigated the efficacy and safety profile of weekly low-dose docetaxel (DTX) with estramustine in comparison with triweekly standard-dose DTX treatment for Japanese patients with castration-resistant prostate cancer (CRPC). Between April 2002 and January 2011, 75 CRPC patients were treated with triweekly DTX (60-75 mg/m(2) every 3 weeks) (standard-dose group), and 76 CRPC patients were treated with weekly low-dose DTX (20-30 mg/m(2) on days 2 and 9 with estramustine 560 mg on days 1-3 and 8-10) every 3 weeks (low-dose group). Prostate-specific antigen (PSA) response and progression-free and overall survival were analyzed in each group. Median serum PSA level of the standard-dose group and low-dose group was 25.0 and 35.5 ng/ml, respectively. In the standard-dose and low-dose groups, 57.8 and 65.2 % of patients, respectively, achieved a PSA decline ≥ 50 %. There was no significant difference in either median time to progression between the standard-dose group (10.0 months) and low-dose group (7.1 months) or in median duration of survival between the standard-dose group (24.2 months) and low-dose group (30.6 months). Multivariate analysis with a Cox proportional hazards regression model showed that DTX treatment protocol did not influence the risk of death. Incidences of grade 3-4 neutropenia, febrile neutropenia, and thrombocytopenia were significantly higher in the standard-dose versus low-dose group (58.7 vs. 7.9 %, 16.0 vs. 3.9 %, and 8.0 vs. 0 %, respectively). For Japanese CRPC patients, weekly low-dose DTX combined with estramustine has similar efficacy to standard-dose DTX but with fewer adverse events.

Non-Governmental Organization (NGO) workers are a group of travellers highly exposed to infectious diseases due to the conditions and duration of their stay. Yet little is known about their knowledge concerning travel related health risks and their prevention. From July to September 2008 a self-administered questionnaire was given to all NGO workers coming for pre-travel consultation and to a comparison group of non-NGO travellers. It examined traveller's knowledge about malaria, traveller's diarrhea, transmission routes of infectious diseases and vaccine availability in both groups. 249 NGO employees and 304 non-NGO travellers were surveyed. Mean age (33.7 vs 34.7 years) and sex ratio (M/F 1.16 vs 1.29) were comparable in both groups. Travel destination was more often Africa (75% vs 39%) and duration of travel was longer in the NGO group (75% vs 15% more than 1 month). NGO travellers had significantly better knowledge about the transmission routes of infectious diseases : percentages of accurate answers varied from 20% for Japanese encephalitis, 31% for yellow fever and 41% for hepatitis A to 70% for dengue and 96% for malaria, versus respectively 9%, 17%, 40%, 54% and 94% for the comparison group. However no differences were observed between the two groups concerning the means to prevent malaria or traveller's diarrhea, or the symptoms necessitating medical consultation. In the sub-group analyses medical professionals (23% of the NGO group) performed better than other NGO workers. Even though the knowledge was slightly better in the NGO group, there are still important gaps and a combined effort of all actors is needed to improve the security of expatriated humanitarian aid workers, in particular for the non-medical staff.

Background A database for hepatocellular carcinoma (HCC) patients who had received hepatic resection was used to develop prediction models for 1-, 3- and 5-year disease-free survival based on a set of clinical parameters for this patient group. Methods The three prediction models included an artificial neural network (ANN) model, a logistic regression (LR) model, and a decision tree (DT) model. Data for 427, 354 and 297 HCC patients with histories of 1-, 3- and 5-year disease-free survival after hepatic resection, respectively, were extracted from the HCC patient database. From each of the three groups, 80% of the cases (342, 283 and 238 cases of 1-, 3- and 5-year disease-free survival, respectively) were selected to provide training data for the prediction models. The remaining 20% of cases in each group (85, 71 and 59 cases in the three respective groups) were assigned to validation groups for performance comparisons of the three models. Area under receiver operating characteristics curve (AUROC) was used as the performance index for evaluating the three models. Conclusions The ANN model outperformed the LR and DT models in terms of prediction accuracy. This study demonstrated the feasibility of using ANNs in medical decision support systems for predicting disease-free survival based on clinical databases in HCC patients who have received hepatic resection.

Social anxiety disorder (SAD) and body dysmorphic disorder (BDD) are characterized by fears of negative evaluation by others (related to one's own incompetence or flawed appearance, respectively). Previous research has shown that individuals with SAD and BDD exhibit difficulty identifying facial expressions and interpretive biases for threat in social situations. The current study aimed at further investigating social cognition in SAD, BDD, and mentally healthy controls (35 individuals per group, respectively). Further, 35 individuals with obsessive-compulsive disorder (OCD) as a clinical control group not characterized by evaluation fears were included. The Movie for the Assessment of Social Cognition (MASC) was applied. It consists of 45 video sequences depicting interactions among four people at a dinner party. Participants are instructed to evaluate each scenario with respect to the characters' emotions, thoughts, and intentions from a bystander perspective (i.e. other-referent context). Only the socially anxious groups (SAD and BDD) were overall less accurate than the other groups in correctly interpreting the social situations, whereas no difference was obtained between the OCD and the control group. Further analyses indicated that the SAD and BDD groups were less accurate in identifying other people's thoughts and intentions, whereas, again, no difference was observed between the OCD and control groups. In addition, the SAD group was less accurate in inferring thoughts and intentions than the OCD group. Interestingly, the groups did not differ with respect to identifying other people's emotions. These results mostly confirm existing cognitive-behavioral models of SAD and BDD emphasizing that biased interpretation of what others think or intend is one of the key factors maintaining social anxiety and appearance-related concerns. Our study shows that this bias generalizes to social situations in which individuals take a third-person observer perspective. Copyright © 2015 Elsevier Ltd. All rights reserved.

The purpose of this study was to analyse body size indices of newborns in Vilnius city (Lithuania) during 2005-2010 in relation with mother's education and ethnicity, and in parallel with the changes of socio-economic situation during the recent years. The present results were based on data (N = 18,084) from the Vilnius University Clinic of Obstetrics and Gynaecology. Comparison of the present Lithuanian data with other newborn studies was made. The analysis of socio-economic and demographic indicators of Lithuania, and the comparison of Gross Domestic Product of various countries was performed. The comparison of body size of newborns' data from the different countries showed that Lithuanian newborns were among the biggest babies. Some statistically significant differences in body size of newborns from different ethnic groups were established. Body length of Lithuanian newborns (M = 52.6 cm, SD = 2.5) was higher than length of Russian, Ukrainian and Romanian newborns. Body weight of Lithuanian newborns (M = 3511 g, SD = 485) was bigger than birth weight of Russian, Polish, Ukrainian and Romanian newborns. The analysis of newborns size by mother's education showed that body weight of neonates from mothers with the university education and from each other education group was bigger in comparison with the babies from respectively lower education group. The comparison of newborns weight by mother's ethnicity in relation to education level revealed nearly no discrepancies between size of newborns from mothers with the same education level at different ethnic group. The analysis of birth parameters by year has not established a statistically significant difference between the mean values for the body weight and body length of the whole investigated contingent of the full-term, single-birth newborns from Vilnius city during the 2005-2010. However, the tendency has been revealed that newborns from mothers with lower education were the most susceptible to negative economic changes after the 2008.

Objective Matrix metalloproteinases are inflammatory biomarkers involved in carotid plaque instability. Our objective was to analyze the inflammatory activity of plasma and carotid plaque MMP-8 and MMP-9 after intravenous administration of hydrocortisone. Methods The study included 22 patients with stenosis ≥ 70% in the carotid artery (11 symptomatic and 11 asymptomatic) who underwent carotid endarterectomy. The patients were divided into two groups: Control Group - hydrocortisone was not administered, and Group 1 - 500 mg intravenous hydrocortisone was administered during anesthetic induction. Plasma levels of MMP-8 and MMP-9 were measured preoperatively (24 hours before carotid endarterectomy) and at 1 hour, 6 hours and 24 hours after carotid endarterectomy. In carotid plaque, tissue levels of MMP-8 and MMP-9 were measured. Results Group 1 showed increased serum levels of MMP- 8 (994.28 pg/ml and 408.54 pg/ml, respectively; P=0.045) and MMP-9 (106,656.34 and 42,807.69 respectively; P=0.014) at 1 hour after carotid endarterectomy compared to the control group. Symptomatic patients in Group 1 exhibited lower tissue concentration of MMP-8 in comparison to the control group (143.89 pg/ml and 1317.36 respectively; P=0.003). There was a correlation between preoperative MMP-9 levels and tissue concentrations of MMP-8 (P=0.042) and MMP-9 (P=0.019) between symptomatic patients in the control group. Conclusion Hydrocortisone reduces the concentration of MMP- 8 in carotid plaque, especially in symptomatic patients. There was an association between systemic and tissue inflammation. PMID:26313719

The Ice Sheet Mass Balance Inter-Comparison Exercise (IMBIE) is a community effort, jointly supported by ESA and NASA, that aims to provide a consensus estimate of ice sheet mass balance from satellite gravimetry, altimetry and mass budget assessments, on an annual basis. The project has five experiment groups, one for each of the satellite techniques and two others to analyse surface mass balance (SMB) and glacial isostatic adjustment (GIA). The basic premise for the exercise is that individual ice sheet mass balance datasets are generated by project participants using common spatial and temporal domains to allow meaningful inter-comparison, and this controlled comparison in turn supports aggregation of the individual datasets over their full period. Participation is open to the full community, and the quality and consistency of submissions is regulated through a series of data standards and documentation requirements. The second phase of IMBIE commenced in 2015, with participant data submitted in 2016 and a combined estimate due for public release in 2017. Data from 48 participant groups were submitted to one of the three satellite mass balance technique groups or to the ancillary dataset groups. The individual mass balance estimates and ancillary datasets have been compared and combined within the respective groups. Following this, estimates of ice sheet mass balance derived from the individual techniques were then compared and combined. The result is single estimates of ice sheet mass balance for Greenland, East Antarctica, West Antarctica, and the Antarctic Peninsula. The participants, methodology and results of the exercise will be presented in this paper.

Traditional manual instruments for total knee arthroplasty are associated with a malalignment rate of nearly 30%. Patient-specific positioning guides, developed to help address alignment, may also influence other intraoperative factors. This study compared a consecutive series of 270 Vanguard total knee replacements performed with Signature patient-specific positioning guides (study group) to a consecutive series of 595 similar knee replacements performed with manual instrumentation (control group). The study group averaged 16.7 fewer minutes in the operating room (p < .001), utilized tibial inserts that averaged 0.4 mm thinner with a smaller proportion of "thick" tibial inserts (14-18 mm) (p < .001), and required fewer transfusions (p = .022). The Signature-derived surgical plan accurately predicted correct femoral and tibial component sizes in 86.3% and 70.3% of the cases, respectively. These rates increased to 99.3% and 99.2%, respectively, for accuracy to within one size of the surgical plan, similar to published values for manual instrumentation.

The possible advantage for weight loss of a diet that emphasizes protein, fat, or carbohydrates has not been established, and there are few studies that extend beyond 1 year. We randomly assigned 811 overweight adults to one of four diets; the targeted percentages of energy derived from fat, protein, and carbohydrates in the four diets were 20, 15, and 65%; 20, 25, and 55%; 40, 15, and 45%; and 40, 25, and 35%. The diets consisted of similar foods and met guidelines for cardiovascular health. The participants were offered group and individual instructional sessions for 2 years. The primary outcome was the change in body weight after 2 years in two-by-two factorial comparisons of low fat versus high fat and average protein versus high protein and in the comparison of highest and lowest carbohydrate content. At 6 months, participants assigned to each diet had lost an average of 6 kg, which represented 7% of their initial weight; they began to regain weight after 12 months. By 2 years, weight loss remained similar in those who were assigned to a diet with 15% protein and those assigned to a diet with 25% protein (3.0 and 3.6 kg, respectively); in those assigned to a diet with 20% fat and those assigned to a diet with 40% fat (3.3 kg for both groups); and in those assigned to a diet with 65% carbohydrates and those assigned to a diet with 35% carbohydrates (2.9 and 3.4 kg, respectively) (P>0.20 for all comparisons). Among the 80% of participants who completed the trial, the average weight loss was 4 kg; 14 to 15% of the participants had a reduction of at least 10% of their initial body weight. Satiety, hunger, satisfaction with the diet, and attendance at group sessions were similar for all diets; attendance was strongly associated with weight loss (0.2 kg per session attended). The diets improved lipid-related risk factors and fasting insulin levels. Reduced-calorie diets result in clinically meaningful weight loss regardless of which macronutrients they emphasize.

NMR lineshape equations for hindered methyl group: a comparison of the semi-classical and quantum mechanical models

NASA Astrophysics Data System (ADS)

Bernatowicz, P.; Szymański, S.

2003-09-01

The semiclassical and quantum mechanical NMR lineshape equations for a hindered methyl group are compared. In both the approaches, the stochastic dynamics can be interpreted in terms of a progressive symmetrization of the spin density matrix. However, the respective ways of achieving the same limiting symmetry can be remarkably different. From numerical lineshape simulations it is inferred that in the regime of intermediate exchange, where the conventional theory predicts occurrence of a single Lorentzian, the actual spectrum can have nontrivial features. This observation may open new perspectives in the search for nonclassical effects in the stochastic behavior of methyl groups in liquid-phase NMR.

To compare the perioperative analgesic effect between methadone and butorphanol in cats. Randomized controlled clinical trial. 22 healthy female domestic cats. Cats admitted for ovariohysterectomy were allocated to a butorphanol group (n = 10) or methadone group (12) and premedicated with butorphanol (0.4 mg/kg [0.18 mg/lb], SC) or methadone (0.6 mg/kg [0.27 mg/lb], SC), respectively, in combination with acepromazine (0.02 mg/kg [0.01 mg/lb], SC). Anesthesia was induced with propofol (IV) and maintained with isoflurane in oxygen. A multidimensional composite scale was used to conduct pain assessments prior to premedication and 5, 20, 60, 120, 180, 240, 300, and 360 minutes after extubation or until rescue analgesia was given. Groups were compared to evaluate isoflurane requirement, propofol requirement, pain scores, and requirement for rescue analgesia. Propofol and isoflurane requirements and preoperative pain scores were not different between groups. During recovery, dysphoria prevented pain evaluation at 5 minutes. Pain scores at 20 minutes were significantly lower in the methadone group, and 6 of 10 cats in the butorphanol group received rescue analgesia, making subsequent pain score comparisons inapplicable. After 6 hours, only 3 of 12 cats in the methadone group had received rescue analgesia. In the present study, methadone appeared to be a better postoperative analgesic than butorphanol and provided effective analgesia for 6 hours following ovariohysterectomy in most cats.

Present work seeks to investigate the biochemical parameters in terms of hypoglycemic and hypolipidemic effects of hydro-methanolic roots extract (HyMREt) of Rauwolfia serpentina in type 1 (alloxan induced) diabetic mice. Animals were divided into seven groups, four control groups, and three were test groups (HyMREt at 50, 100, & 150mg/kg). Each treatment was repeated for 14 days regularly in all seven respective groups and afterwards the body weights, fasting blood glucose (FBG), insulin, and serum lipid levels were determined. Total body weights of diabetic mice treated with HyMREt extract were dose dependently (p<0.05) improved. FBG of test groups were significantly (p<0.0001) reduced in comparison with diabetic controls which displayed elevated fasting blood glucose level. The insulin levels of HyMREt treated groups were significantly (p<0.0001) higher than those of diabetic controls. Lower triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-c) and very low density lipoprotein cholesterol (VLDL-c) whereas elevated level of high density lipoprotein cholesterol (HDL-c) were observed in test dose treated groups. In comparison with diabetic controls, the converse levels of serum lipid were observed. Significant improvement in cardio-protective indices and coronary risk index was also observed. Findings of present study support the hypoglycemic and hypolipidemic potential of HyMREt of R. serpentina.

Specific language impairment (SLI) is usually defined as a developmental language disorder which does not result from a hearing loss, autism, neurological and emotional difficulties, severe social deprivation, low non-verbal abilities. Children affected with SLI typically have difficulties with the acquisition of different aspects of language and by definition, their impairment is specific to language and no other skills are affected. However, there has been a growing body of literature to suggest that children with SLI also have non-linguistic deficits, including impaired motor abilities. The aim of the current study is to investigate language and motor abilities of a group of thirty children with SLI (aged between 4 and 7) in comparison to a group of 30 typically developing children matched for chronological age. The results showed that the group of children with SLI had significantly more difficulties on the language and motor assessments compared to the control group. The SLI group also showed delayed onset in the development of all motor skills under investigation in comparison to the typically developing group. More interestingly, the two groups differed with respect to which language abilities were correlated with motor abilities, however Imitation of Complex Movements was the unique skill which reliably predicted expressive vocabulary in both typically developing children and in children with SLI.

Objective: To evaluate the effect of hydrogen-rich saline (HRS) on dry eye rats induced by subcutaneous injection of scopolamine hydrobromide. Methods: Experiment research. Thirty female Wistar rats at about six weeks old were randomly divided into the normal group, dry eye group, HRS eyedrops group, normal saline eyedrops group (NS), HRS intraperitoneal injection group and NS intraperitoneal injection group, with 5 rats in each group. The dry eye was induced by subcutaneous injection of scopolamine hydrobromide in the latter five groups. The clinical signs of dry eye such as tear volume (SⅠt), tear break-up time (BUT) and corneal epithelial fluorescein staining scores were evaluated on day 7, 14, 21 and 28. On the 28th day, ten eyes in each group were enucleated and processed for paraffin sections for HE, PAS and immunohistochemistry stainings. Analysis of variance was used to test the data, and independent samples t -test was used for comparison between the two groups. Two-way repeated measure ANOVA was used to compare the difference among groups at different time points, one-way ANOVA was used to test the comparisons of the clinical signs at one time, and LSD was used to for comparison between two groups. Results: Before and after the experiment of the day 7, 14, 21, 28, the values of SIt in HRS eyedrops group and HRS intraperitoneal injection group were respectively:(3.625±1.157),(3.313±0.704),(3.250±0.535),(3.313±0.372), (3.375±0.582)mm and (3.500±1.019), (2.893±0.656), (3.321±0.668), (3.179±0.575), (3.214±0.871)mm. The values of BUT were respectively: (2.750±0.707), (2.688±0.594), (2.813±0.753), (3.000±0.756), (2.750±0.707)s and (3.000±0.679), (2.321±0.464), (2.750±0.753), (3.214±0.699), (2.679±0.608)s. The values of fluorescein staining score were respectively: (6.250±0.707), (8.875±0.641), (8.750±0.707), (9.250±0.463), (8.250±1.282) and (6.000±0.679), (9.143±1.027), (8.857±0.770), (9.143±0.949), (8.500±0.760). The difference of SIt, BUT and fluorescein staining score between the groups was statistically significant on the 14th day( F= 5.194, 3.894, 16.487, P< 0.05), the values of SⅠt, BUT and fluorescein staining score of HRS eyedrops group showed significantly better than NS eyedrops group( P< 0.05), HRS intraperitoneal injection group showed significantly better than NS intraperitoneal injection group( P< 0.05), and there was no significant difference between HRS eyedrops group and HRS intraperitoneal injection group( P> 0.05), which remained stable until the day 28. On the 28(th) day, HE, PAS and immunohistochemistry stainings showed the corneal and conjunctival epithelia became smooth and regular, the cell layer number decreased, the tissue hyperplasia and edema were lightened, and the size of goblet cells tended to be normal, and the squamous metaplasia and inflammation were relieved. In HRS eyedrops group and HRS intraperitoneal injection group. Conclusions: HRS eyedrops group and HRS intraperitoneal injection group can relieve the signs of dry eye, improve the pathological damage of cornea and conjunctiva, and protect the ocular surface of a rat dry eye model, which is better than NS groups from the 14(th) day.

Introduction The main objective of any therapeutic intervention aimed at root coverage is to restore the tissue margin to the cemento-enamel junction and to regenerate the lost periodontium. Aim To compare the effectiveness of Platelet Rich Fibrin (PRF) and Amniotic Membrane (AM) in the treatment of gingival recession by Coronally Advanced Flap (CAF) Technique. Materials and Methods Thirty systemically healthy patients who met inclusion-exclusion criteria were selected. After Phase-I therapy, patients were randomly allocated to one of the groups; PRF (Group-A) and Amnion Group (Group-B). Clinical parameters like Plaque Index (PI), Recession Depth (RD) and Width of Keratinized Gingiva (WKG) were measured on the baseline day, three months and six months postoperatively. Mann-Whitney test and Wilcoxon signed ranks test were applied for intergroup and intragroup comparisons respectively. Results Intergroup comparison between platelet rich fibrin and amniotic membrane showed statistically insignificant difference in the recession depth and width of keratinized gingiva at three and six months postoperatively. Conclusion Both the membranes were equally effective in terms of recession coverage and increase in width of keratinized gingiva. PMID:28969268

Sensation and perception, as well as motor functions, have played an important role in the history of psychology. Although tests of these abilities are sometimes included in neuropsychological assessments, comparisons of intraindividual performances on the two sides of the body (as a basis for drawing conclusions and comparisons about the functional status of the two cerebral hemispheres) are in many instances neglected or considered only casually. This study, utilizing several motor and sensory-perceptual tests, compared intraindividual differences on the two sides of the body in a group of controls and a group of persons with brain damage. The results indicated that the sensory-perceptual tests were particularly effective in differentiating the groups. More than 60% of the group with brain damage had greater differences on the two sides of the body than did any of the controls. These findings suggest that a substantial proportion of persons with cerebral disease or damage may be subject to unequivocal identification using sensory-perceptual tests that take only about 20 minutes to administer. These tests may serve a valuable role as an adjunct to comprehensive neuropsychological evaluation and should be further evaluated in this respect.

The United Nations' position is that digital access is a matter involving equality between groups of people, the securing of democratic rights, and equal opportunities for all citizens. This study investigates digital equality in school and leisure between young people with and without disabilities. A cross-sectional design with group comparisons was applied. Participants were young people (10-18 years of age) with disabilities (n=389) and a reference group in about the same ages. Data were collected by a survey focusing on access to and engagement in ICT activities in school and during leisure time. The results demonstrated young people with disabilities had restricted participation in computer use in educational activities, in comparison to young people in general. During leisure time young people with disabilities had a leading position compared to the reference group with respect to internet use in a variety of activities. Beneficial environmental conditions at home (and the reverse in schools) are discussed as parts of the explanation for the differing engagement levels at home and in school, and among young people with disabilities and young people in general. Schools need to prioritise use of ICT by young people with disabilities.

Background. This study was designed to compare the viability of autogenous bone grafts, harvested using different methods, in order to determine the best harvesting technique with respect to more viable cells. Methods. In this animal experimental study, three harvesting methods, including manual instrument (chisel), rotary device and piezosurgery, were used for harvesting bone grafts from the lateral body of the mandible on the left and right sides of 10 rabbits. In each group, 20 bone samples were collected and their viability was assessed using MTS kit. Statistical analyses, including ANOVA and post hoc Tukey tests, were used for evaluating significant differences between the groups. Results. One-way ANOVA showed significant differences between all the groups (P=0.000). Data analysis using post hoc Tukey tests indicated that manual instrument and piezosurgery had no significant differences with regard to cell viability (P=0.749) and the cell viability in both groups was higher than that with the use of a rotary instrument (P=0.000). Conclusion. Autogenous bone grafts harvested with a manual instrument and piezosurgery had more viable cells in comparison to the bone chips harvested with a rotary device. PMID:28748046

Sleep disturbances are frequently reported in patients with posttraumatic stress disorder (PTSD). There is evidence that sleep disturbance is not only a secondary symptom but also a risk factor for PTSD. Sleep-specific psychological treatments provide an alternative to conventional trauma-focused psychological treatments. The current meta-analysis evaluated the efficacy of sleep-specific cognitive-behavioral therapy (CBT) in mitigating PTSD, sleep, and depressive symptoms. A total of 11 randomized controlled trials were included in the meta-analytic comparisons between sleep-specific CBT and waiting-list control groups at posttreatment. Random effects models showed significant reduction in self-report PTSD and depressive symptoms and insomnia severity in the sleep-specific CBT group. The corresponding effect sizes, measured in Hedges' g, were 0.58, 0.44, and 1.15, respectively. The effect sizes for sleep diary-derived sleep onset latency, wake after sleep onset, and sleep efficiency were 0.83, 1.02 and 1.15, respectively. The average study attrition rate of sleep-specific CBT was relatively low (12.8%), with no significant difference from the control group (9.4%). In conclusion, sleep-specific CBT appears to be efficacious and feasible in treating PTSD symptoms. Due to the relatively small number of randomized controlled trials available, further research is warranted to confirm its efficacy and acceptability, especially in comparison to trauma-specific psychological treatments.

The study of the somatotype and food intake among university students is important to carry out internal policies about the improvement of health and prevention of diseases. The aim of this study was to compare the somatotype, nutritional assessment and food intake of university sport and sedentary students. The sample were 1,299 university students (420 males and 879 females) from University of Valencia, during 2008-2009 and 2009-2010, who were evaluated for several anthropometric parameters, the somatotype and the nutritional and food intakes with a 7 day dietary diary. The somatotype was Endo-Mesomorph, Meso-Endomorph, Balanced Endomorph and Meso-Endomorph for sport and sedentary males, and sports and sedentary females, respectively. All groups had a high and low percentage of total calories in comparison with proteins plus lipids, and carbohydrates, respectively, as established in the nutritional objectives for the Spanish population. Low vitamin intakes, including E (in the sport males), A, D and E, folate and biotine (in the sedentary males) and A, D, E, folate and biotine (in the sport and sedentary females) were observed. All groups had a high intake of sodium and a deficit of potassium, calcium, iodine and magnesium. On the other hand, cereal groups were the most important in the energy dairy intake. Disequilibrium in macronutrients and micronutrients reflects the importance of developing food policies among University people to improve this situation. Copyright © 2011 Elsevier España, S.L.

'It's Your Move!' was a 3-year intervention study implemented in secondary schools in Australia as part of the Pacific Obesity Prevention In Communities Project. This paper reports the outcome results of anthropometric indices and relevant obesity-related behaviours. The interventions focused on building the capacity of families, schools and communities to promote healthy eating and physical activity. Baseline response rates and follow-up rates were 53% and 69% respectively for the intervention group (n=5 schools) and 47% and 66% respectively for the comparison group (n=7 schools). Statistically significant relative reductions in the intervention versus comparison group were observed: weight (-0.74 kg, P < 0.04), and standardized body mass index (-0.07, P<0.03), and non-significant reductions in prevalence of overweight and obesity (0.75 odds ratio, P=0.12) and body mass index (-0.22, P=0.06). Obesity-related behavioural variables showed mixed results with no pattern of positive intervention outcomes. In conclusion, this is the first study to show that long-term, community-based interventions using a capacity-building approach can prevent unhealthy weight gain in adolescents. Obesity prevention efforts in this important transitional stage of life can be successful and these findings need to be translated to scale for a national effort to reverse the epidemic in children and adolescents. © 2011 The Authors. obesity reviews © 2011 International Association for the Study of Obesity.

Chemoselective amide formation using O-(4-nitrophenyl)hydroxylamines and pyruvic acid derivatives.

A series of O-(4-nitrophenyl)hydroxylamines were synthesized from their respective oximes using a pulsed addition of excess NaBH(3)CN at pH 3 in 65-75% yield. Steric hindrance near the oxime functional group played a key role in both the ease by which the oxime could be reduced and the subsequent reactivity of the respective hydroxylamine. Reaction of the respective hydroxylamines with pyruvic acid derivatives generated the desired amides in good yields. A comparison of phenethylamine systems bearing different leaving groups revealed significant differences in the rates of these systems and suggested that the leaving group ability of the N-OR substituent plays an important role in determining their reactivity with pyruvic acid. Competition experiments (in 68% DMSO/phosphate buffered saline) using 1 equiv of N-phenethyl-O-(4-nitrophenyl)hydroxylamine and 2 equiv of pyruvic acid in the presence of other nucleophiles such as glycine, cysteine, phenol, hexanoic acid, and lysine demonstrated that significant chemoselectivity is present in this reaction. The results suggest that this chemoselective reaction can occur in the presence of excess α-amino acids, phenols, acids, thiols, and amines.

To examine the risk of obstructive sleep apnea (OSA) in children with cerebral palsy (CP) and/or epilepsy. This cross-sectional study employs the Pediatric Sleep Questionnaire (PSQ), the Gross Motor Function Classification System (GMFCS), and chart review to identify symptoms of OSA in children presenting to a multi-specialty pediatric healthcare institution. Two-hundred and fifteen patients were grouped into those with epilepsy (n=54), CP (n=18), both (n=55), and neither (comparison group, n=88). The comparison group comprised children with developmental disabilities but not children with typical development. Significantly increased PSQ scores (indicating increased risk of OSA) were found among children with CP (58%) and CP with epilepsy (67%) than among the comparison group (27%; p<0.001 and p<0.0001 respectively). Children with both CP and epilepsy had a greater number of increased PSQ scores compared with CP alone (p<0.05). Increased PSQ scores were observed with increasing CP severity as measured using the GMFCS. The PSQ identified more children at risk of OSA (46%) than did the medical record review for symptoms of OSA (8.2%, p<0.001). Children with CP of greater severity or comorbid epilepsy are at increased risk of OSA. This study supports the routine questionnaire-based assessment for OSA as a regular part of the care of all children with CP, especially in those with more severe CP and those with epilepsy. © 2016 Mac Keith Press.

Games with educational intent offer a possible advantage of being more interactive and increasing learner satisfaction. We conducted a two-armed experiment to evaluate student satisfaction and content mastery for an introductory pediatric radiology topic, taught by either an interactive digital game or with a traditional didactic lecture. Medical students participating in a fourth-year radiology elective were invited to participate. Student cohorts were alternatively given a faculty-supervised 1h session playing a simple interactive digital Tic-tac-toe quiz module on pediatric gastrointestinal radiology or a 1h didactic introductory lecture on the same topic. Survey questions assessed the learners' perceived ability to recall the material as well as their satisfaction with the educational experience. Results of an end-of-rotation exam were reviewed to evaluate a quantitative measure of learning between groups. Survey responses were analyzed with a chi-squared test. Exam results for both groups were analyzed with a paired Student's t-test. Students in the lecture group had higher test scores compared to students in the game group (4.0/5 versus 3.6/5, P = 0.045). Students in the lecture group reported greater understanding and recall of the material than students in the game group (P < 0.001 and P = 0.004, respectively). Students in the lecture group perceived the lecture to be more enjoyable and a better use of their time compared to those in the game group (P = 0.04 and P < 0.001, respectively). There was no statistically significant difference between the lecture and game group in ability to maintain interest (P = 0.187). In comparison to pre-survey results, there was a statistically significant decrease in interest for further digital interactive materials reported by students in the game group (P = 0.146). Our experience supported the use of a traditional lecture over a digital game module. While these results might be affected by the specific lecture and digital content in any given comparison, a digital module is not always the superior option.

To assess the surgically induced corneal astigmatism (SIA) introduced by femtosecond laser-assisted clear corneal incisions (CCIs) for cataract extraction and to compare it with the SIA of manually created CCIs. Bascom Palmer Eye Institute, Miller School of Medicine, Miami, Florida, USA. Prospective nonrandomized comparative case series. Eyes received femtosecond laser-assisted CCIs (Group 1) or manual CCIs (Group 2). The surgical plan included 1 primary and 1 secondary port; the sites of the incisions were the same in both groups and were diametrically opposed between the right eye and left eye. The SIA was assessed using the preoperative and 1-month postoperative keratometric values obtained from corneal topography examinations. This study included 72 eyes of 68 patients with a mean age of 69.0 years ± 9.87 (SD) (range 36 to 90 years). Thirty-six eyes received femtosecond laser-assisted CCIs (Group 1) and 36 received manual CCIs (Group 2). The mean preoperative topographic corneal astigmatism was -1.19 ± 0.68 diopters (D) (range 0 to 2.50 D) and -0.92 ± 0.63 D (range 0.10 to 2.45 D) for Group 1 and Group 2, respectively, whereas, 1 month after cataract surgery, it was -1.16 ± 0.63 D (range 0.20 to 2.57 D) and -0.95 ± 0.64 D (range 0.21 to 2.37 D), respectively. Multivariate vector analysis revealed no statistically significant difference between the 2 groups for preoperative astigmatism, postoperative astigmatism, and SIA (P > .05 for all comparisons between Group 1 and Group 2). Femtosecond laser-assisted and manual corneal incisions for cataract surgery did not appear to significantly alter corneal astigmatism, whereas they showed comparable SIA. Drs.

Background: The development of drug delivery systems has improved the therapeutic and toxic properties of existing drugs in therapy. Microemulsion systems are novel vehicles for drug delivery, which have been developed in recent years. These systems are currently of interest to the pharmaceutical scientist because of their considerable potential to act as drug delivery vehicles by incorporating into a wide range of drug molecules. Although these systems improved solubility and bioavailability of drugs, they may have potential toxic effects on the body organs. Objectives: The purpose of this study was to examine a possible hepatotoxic and nephrotoxic effect of lithium carbonate microemulsion (LCME) in a mice model. Materials and Methods: Eighty male Swiss albino mice were randomly allocated to eight experimental groups, as follows: Group 1, as negative control group were treated orally with normal saline (0.9% NaCl); Group 2, received microemulsion base without drug as control group; Groups 3 to 5, received lithium carbonate (LC) solution in doses of 50, 100, and 200 mg/kg, respectively; Groups 6 to 8, received LCME orally in doses of 50, 100, and 200 mg/kg, respectively. All drugs were administered orally for ten consecutive days. Serum glutamate pyruvate aminotransferase (SGPT), serum glutamate oxaloacetate aminotransferase (SGOT), alkaline phosphatase (ALP), blood urea nitrogen (BUN), and plasma creatinine (Cr), as markers of liver and kidney toxicity in treated mice, were measured. Furthermore, the changes of tissue were assessed by histopathologic examination. Results: The findings showed that serum activity of ALP, SGOT, and SGPT and the levels of BUN and Cr in microemulsion base group was greater than normal saline group. However, this difference was not significant. Administration of LC and LCME in all doses resulted in a significant increase in the levels of BUN and serum activity of SGOT and SGPT in comparison to normal saline group (P < 0.05). Histopathological changes were observed in mice treated with LC or LCME. Conclusions: This study showed that subacute oral administration of different doses of LCME with severe toxicity in comparison to the same dose of LC. PMID:25866723

The aim of this study is to compare the oral hygiene status among institutionalized visually impaired children of age between 6 and 20 years given with Braille and audio instructions in Raichur city of Karnataka. A total of 50 children aged between 6 to 20 years were included in this study from a residential school for visually impaired children. These children were randomly divided into two equal groups. One group was given oral hygiene instructions by audio recordings and another written in Braille and were instructed to practice the same. After three months time the oral hygiene status and dental caries experience was recorded and compared using patient performance index. Statistical analysis was done by student paired t test and multiple comparison by Tukey's HSD (honest significant difference) test. The mean PHP (Patient Hygiene Performance) score of group A at baseline was 3.88 compared to 3.90 of group B. At 7 days PHP score of group A and group B was 3.42 and 3.45 respectively. At 3 month PHP score of group A and group B was 2.47 and 2.86 respectively. Even though over a period of time the mean score of PHP index reduced the score comparison between the 2 groups were statistically non significant. In group A the mean difference of PHP score between baseline and 7 days was 0.46, between baseline and 3 months it was 1.40. The PHP score between 7 days and 3 months was 0.94. All the above values were statistically significant. Effective dental health education method has to be instituted for visually impaired children. The present study shows improvement of oral health status in both the study population by decrease in the mean plaque score. Hence continuous motivation and reinforcement in the form of Braille and audio instruction is beneficial to achieve good oral hygiene levels in visually impaired children.

Evaluation of the safety and efficacy of intraurethral Mitomycin C (MMC) hydrogel for prevention of post-traumatic anterior urethral stricture recurrence after internal urethrotomy. A thermoresponsive hydrogel base consisting of 0.8 mg MMC with 1cc water and propylene glycol to PF-127 poloxamer was used in theater. 40 male patients with short, non-obliterated, urethral stricture were randomized into 2 groups: control and MMC. After internal urethrotomy, the MMC group patients received the MMC-Hydrogel while the others were just catheterized. Both groups had their catheters for at least 1 week. After surgery, they were followed up by means of medical history and physical examination, monitoring voiding patterns and retrograde urethrogram at 1 month, 6 months and 1 year after surgery. 40 male patients between 14 to 89 years old (Mean = 54.15) underwent internal urethrotomy. The average age for the control and MMC group was 54.55±21.25 and 53.75±24.75 respectively. In a comparison of age between the two groups, they were matched (P=0.574). Stricture length was 10.7±5.9 and 9.55±4.15 mm for the control and MMC group respectively. There were no statistically meaningful differences between the two groups (P=0.485). Fifteen patients had a history of one previous internal urethrotomy which in a comparison between the two groups meant there was no meaningful difference (P=0.327). During postoperative follow up, total urethral stricture recurrence happened in 12 patients: 10 patients (50%) in control group and 2 patients (10%) in MMC group. The difference was statistically significant (P=0.001). There were no significant complications associated with the MMC injection in our patients. Based on our results, MMC Hydrogel may have an anti-fibrotic action preventing post-traumatic anterior urethral stricture recurrence with no side effects on pre-urethral tissue. Due to our study limitations, our follow up time and the small number of patients, our results were not conclusive and further studies will be needed with a longer follow up time. © 2016 KUMS, All rights reserved.

Objective A group-based eating disorder prevention program wherein young women explore the costs of pursuing the thin ideal reduces eating disorder risk factors and symptoms. However, it can be challenging to identify school clinicians to effectively deliver the intervention. The present study compares the effects of a new Internet-based version of this prevention program, which could facilitate dissemination, to the group-based program and to educational video and educational brochure control conditions at 1- and 2-year follow-up. Method Female college students with body dissatisfaction (N = 107; M age = 21.6 SD = 6.6) were randomized to these four conditions. Results Internet participants showed reductions in eating disorder risk factors and symptoms relative to the two control conditions at 1- and 2-year follow-up (M d = .34 and .17 respectively), but the effects were smaller than parallel comparisons for the group participants (M d = .48 and .43 respectively). Yet the Internet intervention produced large weight gain prevention effects relative to the two control conditions at 1- and 2-year follow-up (M d = .80 and .73 respectively), which were larger than the parallel effects for the group intervention (M d = .19 and .47 respectively). Conclusions Although the effects for the Internet versus group intervention were similar at posttest, results suggest that the effects faded more quickly for the Internet intervention. However, the Internet intervention produced large weight gain prevention effects, implying that it might be useful for simultaneously preventing eating disordered behavior and unhealthy weight gain.

Very little is known on the impact of recurrent disasters on mental health. Aim The present study examines the immediate impact of a recurrent flood on mental health and functioning among an affected population in the rural district of Bahraich, Uttar Pradesh, India, compared with a population in the same region that is not affected by floods. The study compared 318 affected respondents with 308 individuals who were not affected by floods. Symptoms of anxiety and depression were assessed by the Hopkins Symptom Checklist-25 (HSCL-25). Psychological and physical functioning was assessed by using the Short Form-12 (SF-12). The affected group showed large to very large differences with the comparison group on symptoms of anxiety (D = .92) and depression (D = 1.22). The affected group scored significantly lower on psychological and physical functioning than the comparison group (respectively D = .33 and D = .80). However, hierarchical linear regressions showed no significant relationship between mental health and the domains of functioning in the affected group, whereas mental health and the domains of functioning were significantly related in the comparison group. This study found a large negative impact of the recurrent floods on mental health outcomes and psychological and physical functioning. However, in a context with recurrent floods, disaster mental health status is not a relevant predictor of functioning. The findings suggest that the observed mental health status and impaired functioning in this context are also outcomes of another mechanism: Both outcomes are likely to be related to the erosion of the social and environmental and material context. As such, the findings refer to a need to implement psychosocial context-oriented interventions to address the erosion of the context rather than specific mental health interventions.

An experiment with a 2×2 factorial design was performed to compare the efficacy of four diets: a SBM-based diet and a diet containing FB, with and without enzyme supplementation (C, FB, CE and FBE, respectively). In comparison with groups C, higher dry matter content and lower viscosity of the small intestinal digesta were noted in groups FB. The content of short-chain fatty acids (SCFAs) in the small intestinal digesta was higher in groups FB, but SCFA concentrations in the caecal digesta were comparable in groups C and FB. In comparison with control groups, similar BW gains, higher feed conversion ratio (FCR), higher dry matter content of excreta and milder symptoms of footpad dermatitis (FPD) were noted in groups FB. Enzyme supplementation increased the concentrations of acetate, butyrate and total SCFAs, but it did not increase the SCFA pool in the caecal digesta. The enzymatic preparation significantly improved FCR, reduced excreta hydration and the severity of FPD in turkeys. It can be concluded that in comparison with the SBM-based diet, the diet containing 30% of FB enables to achieve comparable BW gains accompanied by lower feed efficiency during the first 8 weeks of rearing. Non-starch polysaccharide-degrading enzymes can be used to improve the nutritional value of diets for young turkeys, but more desirable results of enzyme supplementation were noted in the SBM-based diet than in the FB-based diet.

Hospital admissions are the source of significant health care expenses, although a large proportion of these admissions can be avoided through proper management of chronic disease. In the present study, we evaluate the impact of a proactive chronic care management program for members of a German insurance society who suffer from chronic disease. Specifically, we tested the impact of nurse-delivered care calls on hospital admission rates. Study participants were insured individuals with coronary artery disease, heart failure, diabetes, or chronic obstructive pulmonary disease who consented to participate in the chronic care management program. Intervention (n  = 17,319) and Comparison (n  = 5668) groups were defined based on records of participating (or not participating) in telephonic interactions. Changes in admission rates were calculated from the year prior to (Base) and year after program commencement. Comparative analyses were adjusted for age, sex, region of residence, and disease severity (stratification of 3 [least severe] to 1 [most severe]). Overall, the admission rate in the Intervention group decreased by 6.2% compared with a 14.9% increase in the Comparison group (P  <  0.001). The overall decrease in admissions for the Intervention group was driven by risk stratification levels 2 and 1, for which admissions decreased by 8.2% and 14.2% compared to Comparison group increases of 12.1% and 7.9%, respectively. Additionally, Intervention group admissions decreased as the number of calls increased (P  =  0.004), indicating a dose-response relationship. These findings indicate that proactive chronic care management care calls can help reduce hospital admissions among German health insurance members with chronic disease.

Analysis of changes in self-perception in post-mastectomy patients and its comparison with self-perception of healthy women. The subjects of this study were 50 women. The main group was post-mastectomy patients involved in the meetings of the Amazons Club (25 women). The reference group consisted of 25 healthy women. The method used in the study was the ACL (Adjective Check List) test, identifying 37 dimensions of self-image. Oncological patients completed a test twice (for current and pre-cancer self-image), and healthy women once - for current self. Both groups were selected similarly in respect of education level for the purpose of ensuring a similar level of insight. Retrospective self-image and the current one in the Amazon women group were highly convergent. Existing differences include a reduced need for achievement and dominance, and a lower level of self-confidence. However, the comparison of current self-images in both groups showed a large discrepancy of the results. The Amazon women assess themselves in a much more negative way. Also, their self-image is self-contradictory in certain characteristics. Mastectomy is a difficult experience requiring one to re-adapt and to accept oneself thereafter. The way of thinking about oneself is a defence mechanism helping to cope. The work with patients programmes must, therefore, focus on identifying their emotions and thoughts, especially on those they do not want to accept because of the perceived pressure from the environment to effectively and quickly deal with this difficult situation. The increasing acceptance of personal limitations may help the affected women to adjust psychologically faster and easier.

Our objective is to describe a novel ligamentolysis approach using a subcoronal incision technique and to determine its safety and efficacy. During the last 7 years, 82 consecutive patients had penile augmentation surgery. Ligamentolysis, through a lower abdominal incision (V-Y plasty) in the first 35 males, was performed (Group A), followed by circumcision ligamentolysis in the next 47 males (Group B). The operation time, complications, and the preoperative and postoperative values of penile length and girth along with the self-esteem and relations questionnaire score as well as satisfaction score was calculated before and after the surgery, and a comparison was conducted between the groups. The mean age at presentation was 32 years (range: 18-56 years). Seventy-nine patients suffered from penile dysmorphophobia, and three patients had micropenises (length <7.5 cm). The mean surgical times were 150.7 and 125.2 min for Groups A and B, respectively (P=0.005). Postoperatively, four Group A patients and three Group B patients (11% versus 6%, respectively) experienced penile retraction (P=0.453). Hypertrophic scars were observed in 18 men (51%) in the former [corrected] group. In the circumcision group, no major wound complications were recorded. The length and girth improvements between the groups were similar. In terms of satisfaction and SEAR improvement, the resulting difference for both variables favored the circumcision group (P=0.007 and <0.001, respectively). With strict selection criteria, the circumcision ligamentolysis procedure compared to the V-Y plasty demonstrated improved results in terms of safety, operation time, retraction rate and cosmetic appearance without any compromise in the gained penile size.

To compare the axial length (AL), anterior chamber depth (ACD) and intraocular lens power (IOLP) of IOLMaster and Ultrasound in normal, long and short eyes. Seventy-four normal eyes (≥ 22 mm and ≤ 25 mm), 74 long eyes (> 25 mm) and 78 short eyes (< 22 mm) underwent AL and ACD measurements with both devices in the order of IOLMaster followed by Ultrasound. The IOLP were calculated using a free online LADAS IOL formula calculator. The difference in AL and IOLP between IOLMaster and Ultrasound was statistically significant when all three groups were combined. The difference in ACD between IOLMaster and Ultrasound was statistically significant in the normal group (P<0.001) and short eye group (P<0.001) but not the long eye group (P = 0.465). For the IOLP difference between IOLMaster and Ultrasound in the normal group, the percentage of IOLP differences <|0.5|D, ≥|0.5|D<|0.75|D, ≥|0.75|D<|1.0|D, and ≥|1.0|D were 90.5%, 8.1%, 1.4% and 0%, respectively. For the long eye group, they were 90.5%, 5.4%, 4.1% and 0%, respectively. For the short eye group, they were 61.5%, 23.1%, 10.3%, and 5.1%, respectively. IOLMaster and Ultrasound have statistically significant differences in AL measurements and IOLP (using LADAS formula) for normal, long eye and short eye. The two instruments agree regarding ACD measurements for the long eye group, but differ for the normal and short eye groups. Moreover, the high percentage of IOLP differences greater than |0.5|D in the short eye group is noteworthy.

To compare the efficacy and treatment session numbers of acetic acid to that of ethanol sclerotherapy for the treatment of simple renal cysts. Between February 2004 and June 2013, 86 patients with simple renal cysts underwent percutaneous aspiration and injection of 50 %-acetic-acid (42 cysts) and 95 %-ethanol (44 cysts). The patient demographics, volume reduction rate, number of treatment sessions, and complications were then analyzed. The volume reduction rate was 94.1 ± 7.6 % in the 50 %-acetic acid group and 94.7 ± 11.7 % in the 95 %-ethanol group, and without a statistical difference. The rates of complete remission, partial remission, and no response were 57.1, 42.9 and 0 %, respectively, for the acetic acid group, and 70.5, 25.0, and 4.5 %, respectively, for the ethanol group. No statistical difference was observed between the two groups. Compared to the acetic acid group, the ethanol group had a higher number of treatment sessions, i.e. 1.10 ± 0.30 in the acetic acid group and 1.80 ± 0.79 in the ethanol group. Mild flank pain was a minor complication that occurred in both groups. Acetic acid seems to have equivalent sclerosing effects on simple renal cysts compared with those of ethanol despites of fewer treatment sessions.

A double-blind, randomized, parallel and active-controlled clinical study was conducted to evaluate the anti-hypertensive effect as well as the tolerability of Olive leaf extract in comparison with Captopril in patients with stage-1 hypertension. Additionally, this study also investigated the hypolipidemic effects of Olive leaf extract in such patients. It consisted of a run-in period of 4 weeks continued subsequently by an 8-week treatment period. Olive (Olea europaea L.) leaf extract (EFLA(®)943) was given orally at the dose of 500 mg twice daily in a flat-dose manner throughout the 8 weeks. Captopril was given at the dosage regimen of 12.5 mg twice daily at start. After 2 weeks, if necessary, the dose of Captopril would be titrated to 25 mg twice daily, based on subject's response to treatment. The primary efficacy endpoint was reduction in systolic blood pressure (SBP) from baseline to week-8 of treatment. The secondary efficacy endpoints were SBP as well as diastolic blood pressure (DBP) changes at every time-point evaluation and lipid profile improvement. Evaluation of BP was performed every week for 8 weeks of treatment; while of lipid profile at a 4-week interval. Mean SBP at baseline was 149.3±5.58 mmHg in Olive group and 148.4±5.56 mmHg in Captopril group; and mean DBPs were 93.9±4.51 and 93.8±4.88 mmHg, respectively. After 8 weeks of treatment, both groups experienced a significant reduction of SBP as well as DBP from baseline; while such reductions were not significantly different between groups. Means of SBP reduction from baseline to the end of study were -11.5±8.5 and -13.7±7.6 mmHg in Olive and Captopril groups, respectively; and those of DBP were -4.8±5.5 and -6.4±5.2 mmHg, respectively. A significant reduction of triglyceride level was observed in Olive group, but not in Captopril group. In conclusion, Olive (Olea europaea) leaf extract, at the dosage regimen of 500 mg twice daily, was similarly effective in lowering systolic and diastolic blood pressures in subjects with stage-1 hypertension as Captopril, given at its effective dose of 12.5-25 mg twice daily.

Aim: To compare the fracture resistance of teeth restored with fiber-reinforced composite (FRC) posts and experimental dentin posts milled from human root dentin. Materials and Methods: Thirty maxillary central incisors were divided into three groups of ten each. Twenty teeth were restored with FRC posts and solid dentin posts and numbered as Groups 2 and 3 respectively while Group 1 acted as the control, without any post. The teeth were loaded at 135° angle to their long axes after core build-up and the failure loads were recorded. Results: One-way Analysis of Variance (ANOVA) and Bonferroni multiple comparisons revealed a significant difference among test groups with the control group showing the highest fracture resistance, followed by the dentin post group and lastly the FRC post group. Conclusions: Teeth restored with dentin posts exhibited better fracture resistance than those restored with FRC posts. PMID:22144812

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.

The primary objective of this study was to determine if activation of coagulation and fibrinolysis occurs in canine pleural effusions. Thirty-three dogs with pleural effusions of different origin were studied. Pleural effusion fibrinogen concentrations were significantly lower, while pleural fibrin-fibrinogen degradation products (FDPs) and D-dimer concentrations were significantly higher than those in plasma (P < 0.001 for all comparisons). These results show that, in canine pleural fluids, there is evidence of coagulation activation and fibrinolysis. The secondary aims of the current study were to determine if primary hyperfibrinolysis ([PHF] i.e., elevated plasma FDPs with a normal D-dimer concentrations), occurs in dogs with pleural effusion, and whether the presence of a concurrent inflammatory process may have activated the hemostatic cascade, with its intrinsically linked secondary hyperfibrinolysis, masking the concurrent PHF. The previously 33 selected dogs with pleural effusion (group 1) were compared to two control groups of 33 healthy (group 2) and 33 sick dogs without pleural effusion (group 3). Serum fibrinogen, FDPs, D-dimer, C-reactive protein (CRP), fibrinogen/CRP ratio, and frequency of PHF were determined. Fibrinogen, FDPs, D-dimer and CRP concentrations in group 1 were significantly increased compared to group 2 (P < 0.001 for all comparisons). FDPs and CRP concentrations in group 1 were also significantly increased compared to group 3 (P = 0.001 and P < 0.001, respectively). The fibrinogen/CRP ratio was significantly decreased in group 1 compared to groups 2 and 3 (P < 0.001 for both comparison). The frequency of PHF was significantly higher in group 1 compared to groups 2 (P = 0.004), but not compared to group 3. These results support the hypothesis that PHF occurs significantly more often in dogs with pleural effusion compared to healthy dogs. Nevertheless, the decrease in the fibrinogen/CRP ratio in group 1 compared to group 3, considering the higher FDPs and similar D-dimer concentrations, would suggest that PHF is also more frequent in dogs with pleural effusion compared to sick control dogs, and that this phenomenon is hidden due to concurrent secondary hyperfibrinolysis.

To observe and compare the clinical curative effect of the plasma exchange (PE) and intravenous immunoglobulin (IVIg) for Guillian-Barre Syndrome (GBS). Overall, 64 adult patients with GBS for PE and IVIg treatment, respectively, and nerve function were observed pre-treatment and at 1 week/2 weeks after completion of treatment; the blood immunoglobulin, complement, fibrinogen (Fib) and monocyte percentage (MON%) were detected simultaneously. After PE treatment, nerve function defect appeared to improve better than the IVIg group and clinical effect was better than the IVIg group. Treatment effective rates of the two groups after 2 weeks, respectively, are 96 and 79%. PE and IVIg can significantly reduce the GBS patients' blood immunoglobulin IgG, IgA, IgM, C3 and C4, but these were significantly lower in the PE group than in the IVIg group. Fib and MON% were significantly lower in the PE group than in the IVIg group. Both PE and IVIg have a high response as therapy and are reasonable therapeutic options for GBS. However, PE treatment has a more significantly curative effect, as it can effectively improve symptoms and be helpful in the early rehabilitation of patients. © 2014 British Blood Transfusion Society.

It is inconclusive that periodontitis is an independent risk factor for adverse pregnancy outcomes. This study aims to investigate the association between maternal periodontitis and preterm and/or low birth weight babies. This was a prospective cross-sectional study. After prior informed consent, 3500 postpartum mothers were selected from various hospitals in Tamil Nadu and categorized into the following groups: group-1 - Normal term normal birth weight ( n = 1100); Group-2 - Preterm normal birth weight ( n = 400); Group-3 - preterm low birth weight (PTLBW) ( n = 1000); and Group-4 - Normal term low birth weight ( n = 1000). Periodontal examination was done, and risk factors were ascertained by means of questionnaire and medical records. Comparison between case groups and control groups were done, odds ratio (OR) was calculated, and statistical significance were assessed by Chi-square tests. To control for the possible confounders, all variables with P < 0.05 were selected and entered into multivariate regression model, and OR and 95% confidence limits were again estimated. SPSS-15 software was used. Periodontitis was diagnosed in 54.8%, 52.3%, 53.8%, 59.4%, respectively. On comparison between the groups, none of periodontal parameters showed significant association except for the crude association observed in Group-4 for mild periodontitis (OR - 1.561; P = 0.000) and PTLBW. Periodontitis is not a significant independent risk factor, and obstetric factors contribute a major risk for preterm and/or low birth weight babies.

Present study evaluated the efficacy of natural derivative irrigants, Morinda citrifolia juice (MCJ), Aloe Vera and Propolis in comparison to 1% sodium hypochlorite with passive ultrasonic irrigation for removal of the intraradicular E. faecalis biofilms in extracted single rooted human permanent teeth. Biofilms of E. faecalis were grown on the prepared root canal walls of 60 standardized root halves which were longitudinally sectioned. These root halves were re-approximated and the samples were divided into five groups of twelve each. The groups were, Group A (1% NaOCl), Group B (MCJ), Group C (Aloe vera), Group D (Propolis) and Group E (Saline). These groups were treated with passive ultrasonic irrigation (PUI) along with the respective irrigants. The root halves were processed for scanning electron microscopy. Three images (X2.5), coronal, middle and apical, were taken for the twelve root halves in each of the five groups. The images were randomized and biofilm coverage assessed independently by three calibrated examiners, using a four-point scoring system. 1% NaOCl with passive ultrasonic irrigation (PUI) was effective in completely removing E. faecalis biofilm and was superior to the natural irrigants like MCJ, Aloe vera and Propolis tested in this study. 1% NaOCl used along with passive ultrasonic irrigation was effective in completely removing E. faecalis biofilm when compared to natural irrigants (MCJ, Aloe Vera and Propolis).

To evaluate phenylalanine plasma profile in preterm newborns fed different human milk diets. Twenty-four very-low weight preterm newborns were distributed randomly in three groups with different feeding types: Group I: banked human milk plus 5% commercial fortifier with bovine protein, Group II: banked human milk plus evaporated fortifier derived from modified human milk, Group III: banked human milk plus lyophilized fortifier derived from modified human milk. The newborns received the group diet when full diet was attained at 15 ± 2 days. Plasma amino acid analysis was performedon the first and last day of feeding. Comparison among groups was performed by statistical tests: one way ANOVA with Tukey's post-test using SPSS software, version 20.0 (IBM Corp, NY, USA), considering a significance level of 5%. Phenylalanine levels in the first and second analysis were, respectively, in Group I: 11.9 ± 1.22 and 29.72 ± 0.73; in Group II: 11.72 ± 1.04 and 13.44 ± 0.61; and in Group III: 11.3 ± 1.18 and 15.42 ± 0.83 μmol/L. The observed results demonstrated that human milk with fortifiers derived from human milk acted as a good substratum for preterm infant feeding both in the evaporated or the lyophilized form, without significant increases in plasma phenylalanine levels in comparison to human milk with commercial fortifier.

The objective of this study was to explore whether the inhibition of potassium inwardly rectifying channel (Kir3.1) with short interfering RNA (siRNA) can improve bradycardia in an experimental sinus bradycardia rat model. 54 Sprague Dawley (SD) rats were randomly divided into three groups: experimental group, control group, and sham group. Sinus bradycardia model was established in SD rats through chemical ablation of sinoatrial (SA) node with 20% formaldehyde. Variations of Kir3.1 expression at mRNA and protein level were examined with qPCR and Western blotting. Electrocardiograms (ECG) of rats at 3 days and 1, 2, 3, and 4 weeks after chemical ablation and lentivirus injection were recorded and differences were compared among the three groups. The differences among multiple groups were analyzed by one-way analysis of variance (ANOVA). It was found through RT-PCR and Western blot that the mRNA and protein levels of Kir3.1 at sinoatrial node areas were decreased by 42 ± 7% and 31 ± 7% in comparison with control group, respectively (P < 0.05 in both comparisons) after 4 weeks of chemical ablation/injection. Whole-cell patch clamp data showed that the lentiviral construct could significantly inhibit the potassium current of a muscarinic acetylcholine-sensitive K + channel, I KACh . ECG data showed that the heart rate of experimental group increased after 3 days of chemical ablation/injection and lasted for at least 4 weeks after the chemical ablation/injection (heart rate increased 15.4 ± 3.8% in comparison with control group, P < 0.05). Inhibition of Kir3.1 could rescue sinus bradycardia induced by chemical ablation of SA node with 20% formaldehyde at least partly through inhibiting I KACh channel.

To evaluate the effects of presence of hydronephrosis on micropercutaneous nephrolithotomy (micro-PNL) surgery. A retrospective analysis of 112 patients who underwent microperc surgery between December 2012 and April 2014 was performed. Patients were evaluated in two groups according to whether the presence of hydronephrosis. Stone size and location, fluoroscopy and operation time, stone-free rates and patient-related parameters were prospectively recorded into a centralized computer-generated system. A total of 58 patients in Group 1 with hydronephrosis and 54 patients in Group 2 with no hydronephrosis were analyzed. There was no statistically significant difference in terms of stone sizes and body mass indexes (BMI) in comparison of groups (155.2 ± 93.06 vs. 143.70 ± 70.77 mm(2), p = 0.856 and 27.6 ± 4.2 vs. 26.7 ± 3.2 kg/m(2), p = 0.625). The success rates were similar (91.3 vs. 92.5%, p = 0.341). While the mean operation time and fluoroscopy time in Group 1 were 44.2 ± 23.62 min and 105.3 ± 47 s, it was 38.8 ± 26.4 min and 112.53 ± 68.3 s in Group 2, but there was no statistical difference in comparison of both groups. The mean attempts of percutan puncture were 1.35 ± 0.47 in Group 1 and 1.76 ± 0.31 in Group 2 (p = 0.185). We also found no statistical differences regarding mean hemoglobin change and hospitalization time, respectively (p = 0.685 and p = 0753). In comparison of grades of hydronephrosis, there was no statistically significant difference in subgroups analysis. The presence of hydronephrosis does not affect success rates and operative time in micro-PNL procedures significantly. Micropercutaneous nephrolithotomy is technically feasible and efficacious both in hydronephrotic and non-hydronephrotic kidneys.

Physical activity (PA) among breast cancer survivors (BCS) can improve this population's health and quality of life (QoL). This study evaluated the effectiveness of a combined smartwatch- and social media-based health education intervention on BCS's health outcomes. Thirty BCS ( X ¯ age = 52.6 ± 9.3 years; X ¯ Wt = 80.2 ± 19.6 kg) participated in this 10-week, 2-arm randomized trial, with BCS randomized into: (1) experimental group ( n = 16): received Polar M400 smartwatches for daily PA tracking and joined a Facebook group wherein Social Cognitive Theory-related PA tips were provided twice weekly; and (2) comparison group ( n = 14): only joined separate, but content-identical Facebook group. Outcomes included PA, physiological, psychosocial, and QoL variables. Specifically, PA and energy expenditure (EE) was assessed by ActiGraph GT3X+ accelerometers while physiological, psychosocial, and QoL were examined via validated instruments at baseline and post-intervention. No baseline group differences were observed for any variable. Ten BCS dropped out of the study (experimental: 4; comparison: 6). Compared to completers, dropouts differed significantly on several outcomes. Thus, a per-protocol analysis was performed, revealing significant group differences for changes in social support ( t = -2.1, p = 0.05) and barriers ( t = -2.2, p = 0.04). Interestingly, the comparison group demonstrated improvements for both variables while the intervention group demonstrated slightly decreased social support and no change in barriers. Notably, both groups demonstrated similarly increased daily light PA, moderate-to-vigorous PA, EE, and steps of 7.7 min, 5.1 min, 25.1 kcals, and 339 steps, respectively, over time. Despite extensive user training, several experimental BCS found the Polar M400 use difficult-possibly decreasing intervention adherence. Future interventions should utilize simpler smartwatches to promote PA among middle-aged clinical/non-clinical populations.

The aim of this study was compare changes in upper body muscle strength and size in trained men performing resistance training (RT) programs involving multi-joint plus single-joint (MJ+SJ) or only multi-joint (MJ) exercises. Twenty young men with at least 2 years of experience in RT were randomized in 2 groups: MJ+SJ (n = 10; age, 27.7 ± 6.6 years) and MJ (n = 10; age, 29.4 ± 4.6 years). Both groups trained for 8 weeks following a linear periodization model. Measures of elbow flexors and extensors 1-repetition maximum (1RM), flexed arm circumference (FAC), and arm muscle circumference (AMC) were taken pre- and post-training period. Both groups significantly increased 1RM for elbow flexion (4.99% and 6.42% for MJ and MJ+SJ, respectively), extension (10.60% vs 9.79%, for MJ and MJ+SJ, respectively), FAC (1.72% vs 1.45%, for MJ and MJ+SJ, respectively), and AMC (1.33% vs 3.17% for MJ and MJ+SJ, respectively). Comparison between groups revealed no significant difference in any variable. In conclusion, 8 weeks of RT involving MJ or MJ+SJ resulted in similar alterations in muscle strength and size in trained participants. Therefore, the addition of SJ exercises to a RT program involving MJ exercises does not seem to promote additional benefits to trained men, suggesting MJ-only RT to be a time-efficient approach.

Before the era of intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment, only prevention for visual loss might have been achieved in a limited number of neovascular age-related macular generation (nAMD) patients with different treatment options. To compare the efficacy of intravitreal bevacizumab (IVB) for the treatment of nAMD between phakic and pseudophakic eyes. The newly diagnosed nAMD patients were included in this retrospective study. The patients were divided into the phakic and pseudophakic groups. Initially, the patients received three consecutive, monthly, IVB injections, and then the treatment was continued on an as-needed regimen. The patients were examined monthly, and the data at the baseline, at 3, 6, 9, and 12 months and at the last follow-up were evaluated. The changes in the visual acuity (VA), central retinal thickness (CRT) and the number of injections were compared between the two groups. The study included 62 eyes of 62 patients (39 phakic, and 23 pseudophakic patients). The mean follow-up time was 19.7 and 17.2 months in the phakic and pseudophakic groups, respectively (p=0.06). The mean Log MAR VA at the baseline, 12 months and the last follow-up was 0.82, 0.72 and 0.75 in the phakic group and 0.77, 0.67, and 0.68 in the pseudophakic group, respectively. The change in the mean BCVA from the baseline to 12 months and at the last follow-up was not statistically different between the two groups (p=0.9 and p=0.7, respectively). The mean injection number at 12 months was 4.5 and 4.9 in the phakic and pseudophakic group, respectively (p=0.2). The beneficial effect of IVB is equal in both the phakic and pseudophakic group of nAMD patients. The functional and anatomical outcomes of the treatment and the number of injections were similar in the two groups. © NEPjOPH.

Chemical matricectomy is performed mainly by two agents: phenol and sodium hydroxide. Both agents have excellent cure rates, but there are no data about the comparison of postoperative healing periods. This study was designed to compare the postoperative morbidity rates of sodium hydroxide and phenol matricectomies. Forty-six patients with 154 ingrowing nail sides were treated with either sodium hydroxide or phenol matricectomy. In the postoperative period, the patients were evaluated for the duration and severity of pain, drainage, and peripheral tissue destruction; complete healing periods; and overall success rates. The incidence of pain was higher in the sodium hydroxide group on the first visit, on the second day, but all patients became pain-free after that. The incidence and duration of drainage and peripheral tissue destruction was significantly higher in the phenol group. The mean period for complete recovery was 10.8 days in the sodium hydroxide group, whereas it was 18.02 days in the phenol group. The overall success rates in the sodium hydroxide and phenol groups were found to be 95.1 and 95.8%, respectively. Both sodium hydroxide and phenol are effective agents giving high success rates, but sodium hydroxide causes less postoperative morbidity and provides faster recovery.

Mobilization techniques for peripheral blood stem cell (PBSC) collection include the administration of chemotherapy followed by hematopoietic growth factors or growth factors alone. Two forms of recombinant human granulocyte colony-stimulating factor (rhG-CSF) are available for PBSC mobilization: lenograstim and filgrastim which are the glycosylated and non-glycosylated forms respectively. In order to determine the influence of the two forms of G-CSF following chemotherapy on PBSC collection, we conducted a retrospective study in 126 patients with various hematological malignancies: 65 and 61 for the lenograstim and filgrastim groups respectively. No significant differences between the two groups were observed in terms of sex, age and diagnosis. Prior therapies and PBSC mobilization regimen were also equivalent. No significant difference was observed between the groups for the median CD34+ cells harvested. The number of leukapheresis necessary to obtain a minimal number of 3 x 10(6) CD34+ cells/kg was equivalent for the two groups. The proportion of patients affected by a failure in PBSC collection was similar in the two groups. Our data suggest that lenograstim and filgrastim are equivalent for PBSC mobilization after chemotherapy.

The aim of the study was to study the effects of a flexible shift system (based on self-determined work hours) with respect to sleep/wake complaints and subjective health. The comparison group was a rapidly rotating shift system, with frequently occurring quick returns. A secondary aim was to examine the relation between work hour characteristics indicating compressed or difficult rosters (e.g. number of workdays in a row, frequency of quick returns and long work shifts) and subjective sleep and sleepiness, within the flexible shift system group. The sample of the analysis included 533 randomly selected police officers, of which 26% were females. The participants answered a questionnaire. The results showed that the flexible shift system group did not differ with respect to sleep/wake complaints and subjective health. However, the flexible shift group obtained more sleep in connection with the shifts, probably because of longer rest time between shifts. Thus, they worked less quick returns and long work shifts. The association between work hour characteristics and sleep/wake complaints was weak in the flexible shift group. Instead, sleep/wake problems were mainly associated with the attitude to work hours.

A trial involving 6,169 feedlot calves was conducted under commercial feedlot conditions in western Canada to compare the relative efficacy of treatment with a combination of oxfendazole and fenthion (O/F) versus ivermectin (I) with respect to the outcome variables, final weight, gain, days on feed (DOF), dry matter intake (DMI), average daily gain (ADG), dry matter intake to gain ratio (DM:G), and morbidity, mortality, and carcass grade parameters. There were no significant differences (p ≥ 0.05) between the treatment groups for final weight, gain, DOF, DMI, ADG and DM:G. In addition, there were no significant differences (p ≥ 0.05) in the carcass grading parameters between the treatment groups. The bovine respiratory disease (BRD) relapse rates, the overall mortality rates, and the cause specific mortality rates were not significantly different (p ≥ 0.05) between the treatment groups. The BRD treatment rate in the O/F group was significantly lower (p ≤ 0.05) than in the I group, but this difference was not economically important. These data indicate that a combination of oxfendazole and fenthion is comparable to ivermectin with respect to performance, animal health, and carcass grade parameters. PMID:17424076

Acute lymphoblastic leukaemia (ALL) is one of the most common cancers in children. In Poland, since November 2002 a new protocol of risk stratification has been recommended for assessment of risk factors and for choosing therapy regimens. assessment of accuracy of protocol ALL-IC 2002 in comparison to previously used risk stratification protocols. ALL was diagnosed in 100 children (44 girls, 56 boys; 1-18 years of age) in the Department of Pediatric Hematology and Oncology, Warsaw Medical University, over the period from November 2002 to November 2006. According to the ALL-IC 2002 protocol the patients were divided into three risk groups: SR-standard, IR-intermediate and HR-high. The stratification was by age, leukocyte count, cytogenetic changes, early response to prednisone therapy and bone marrow remission. In the previously used risk stratification protocols-BFM-90, only hepatosplenomegaly and the number of blasts in peripheral blood (PB) were considered, and the patients were divided into three risk groups: low (LRG<0.8), medium (MRG) and high (HRG>1.2). out of the 100 patients qualified for treatment regimens according to the ALL-IC 2002 protocol, 97 entered remission, 11 died and 3 had a relapse. Under the ALL-IC 2002 protocol these children were stratified into the following groups: SR-31%, IR-44% and HR-25%. In the previously used stratification, there would be 26% children in low, 46% in the medium and 28% in the high risk group. According to the BFM-90 protocol 18/31 (58%) and 16/44 (36%) patients from the SR and IR groups respectively would be given more intensive treatment. On the other hand 11/44 (25%) and 14/25 (56%) patients from the IR and HR groups respectively would be given less intensive treatment. 1. ALL-IC 2002 protocol in comparison with the previously used protocol BFM-90, changes the qualification of children with ALL for the SR, IR and HR risk groups. This is linked to basic change of treatment protocol, adequate to severity of disease. 2. Children with ALL qualified according to protocol BFM-90 for moderate risk group (IR) constitute a mixed group in the ALL-IC 2002 classification. Part of the children was moved to the standard risk group (SR), part to high risk group (HR), and the rest remains in the intermediate risk category (IR). 3. Further studies are needed on stratification validity according to ALL-IL 2002 and on the need of further modification (eg assessment of additional factors) in order to decide on the best treatment, adequate to severity of disease.

The efficacy of anterior fusion using zero-profile implant (Zero-P) in the surgical treatment of degenerative cervical disease was investigated through radiographic and clinical comparisons with existing treatments using autograft or allograft and anterior plating. A total of 130 patients who underwent anterior decompression and fusion for degenerative cervical spine disease with a follow-up of at least 1 year were analyzed retrospectively. The cases were divided into three groups: autograft and plate (38 cases, group A), allograft and plate (44 cases, group B), and Zero-P (48 cases, group C). Maintenance of lordosis, extent of subsidence, and fusion were evaluated radiologically and compared among preoperative, postoperative, and final follow-up time points. In addition, changes in Visual Analog Scale (VAS) and Neurologic Disability Index (NDI) scores and the presence of complications were evaluated for clinical analysis. Operation time was significantly less in group C (p = 0.007, 0.002). Maintenance of entire and segmental lordosis after surgery was better in groups A and B compared with group C (p = 0.002, 0.001); however, the extent of loss of lordosis from the surgery to the final follow-up did not show any significant differences. Regarding the extent of subsidence, the increase of height between the vertebral bodies after the surgery was 3.10, 2.89, and 2.68 mm in group A, group B, and group C, respectively (p = 0.14), and changed to - 1.27, - 2.41, and - 1.2 mm at the final follow-up (p = 0.012). VAS and NDI scores were improved from 7.2 to 3 and 34 to 12, respectively, but there were no significant differences. Nonunion occurred in two cases in both group B and group C. In terms of clinical complications, two cases of persistent donor site pain were found in group A; one case of persistent dysphagia was found in both group A and group B. Anterior cervical fusion using Zero-P has a shorter operation time and less subsidence compared with conventional surgical techniques. Thus it can be considered a useful technique for the surgical treatment of degenerative cervical disease. Georg Thieme Verlag KG Stuttgart · New York.

The anterior rotator cable is critical in force transmission of the rotator cuff. However, few clinical studies have examined the correlation between the integrity of the anterior supraspinatus tendon and surgical outcomes in patients with rotator cuff tears. To compare the clinical and structural outcomes of the arthroscopic repair of full-thickness rotator cuff tears with and without anterior disruption of the supraspinatus tendon. Cohort study; Level of evidence, 3. One hundred eighty-one shoulders available for magnetic resonance imaging (MRI) at least 6 months after arthroscopic rotator cuff repair, with a minimum 1-year follow-up, were enrolled. The anterior attachment of the rotator cable was disrupted in 113 shoulders (group A) and intact in 68 shoulders (group B). The mean age at the time of surgery in groups A and B was 59.6 and 59.2 years, respectively, and the mean follow-up period was 24.2 and 25.1 months, respectively. There were statistically significant differences in the preoperative tear size and pattern and muscle fatty degeneration between the 2 groups ( P = .004, P = .008, and P < .001, respectively). At final follow-up, the mean visual analog scale (VAS) for pain score during motion was 1.31 ± 0.98 and 1.24 ± 0.90 in groups A and B, respectively ( P = .587). The mean Constant score was 77.5 ± 11.2 and 78.0 ± 11.9 points in groups A and B, respectively ( P = .875). The mean University of California, Los Angeles score was 30.5 ± 4.1 and 31.0 ± 3.0 points in groups A and B, respectively ( P = .652). In assessing the repair integrity on postoperative MRI, the retear rate was 23.9% and 14.7% in groups A and B, respectively ( P = .029). Irrespective of involvement in the anterior attachment of the rotator cable, the mean 24-month follow-up demonstrated excellent pain relief and improvement in the ability to perform activities of daily living after arthroscopic rotator cuff repair. However, tears with anterior disruption of the rotator cable showed a significantly larger and more complex tear pattern and more advanced fatty degeneration. Additionally, the retear rate was significantly higher in patients with a tear involving the anterior attachment of the rotator cable.

A cascade of pathophysiological events occurs with the ascension to high altitude (H). We have performed studies on the effects of exposure to H on the pharmacokinetics of drugs. The hypothesis behind these studies has been that the exposure to H, which produces marked physiological changes in the body, may alter pharmacokinetics, and consequently, pharmacodynamics. Our previous studies suggest that drugs highly bound to plasma proteins are most likely to exhibit altered disposition. In continuation of our research, we selected furosemide which is about 98% bound to plasma proteins, renally excreted and has low binding to red blood cells. Furosemide (40 mg) was administered orally to 3 groups of young healthy volunteers. One group who had been residing at sea level (group L), the same group after 15 hours of exposure to high altitude (3,600 m, group HA) and a group of volunteers living at H for at least 6 months (group HC). Our results are in accordance with the most recent pharmacokinetic studies on furosemide in which a terminal half-life of approximately 20-30 h was reported. Total proteins were 9.3% and 12.7% higher in groups HA and HC, respectively, than in group L. Albumin in group HC was 8.2% higher than group L. Bilirubin increased 17.7% and 41.2% in groups HA and HC, respectively, in comparison with group L. A rapid disposition rate constant in groups HA and HC was the only pharmacokinetic parameter that was significantly different from those in group L. Concentration of furosemide in plasma water increased significantly after H exposure, thus, the binding diminished from 97.2% in group L to 95.1% and 91.1% in groups HA and HC, respectively. Exposure to H produces an increase in the free fraction of furosemide in humans, which could be of therapeutic importance.

Recently, 5-hydroxytryptamine 3 (5-HT3) receptor antagonists have been reported to prevent postanesthetic shivering. This placebo-controlled study was performed to evaluate the efficacy of granisetron, a 5-HT3 antagonist, in comparison with meperidine and tramadol in preventing postanesthetic shivering. In this prospective, randomized, double-blind study, 132 ASA I and II patients undergoing elective orthopedic surgery under standardized general anesthesia were included. At the end of surgery, patients were randomly assigned to one of four groups (each group n = 33) using a double-blinded protocol. Group T received 1 mg/kg tramadol, group G received 40 microg/kg granisetron (an antiemetic dose), group M received 0.4 mg/kg meperidine, and group P received saline 0.9% as placebo. Shivering was graded according to the following: 0 = no shivering; 1 = piloerection, peripheral vasoconstriction or peripheral cyanosis without other cause; 2 = visible muscular activity confined to one muscle group; 3 = visible muscular activity in more than one muscle group; and 4 = gross muscular activity involving the entire body. The emergence time from anesthesia, defined as the time between withdrawal of isoflurane and tracheal extubation, was documented. The number of patients with observable shivering was 19 in group P, nine in group G, seven in group T and six in group M. Granisetron significantly reduced the incidence of shivering in comparison with placebo (p = 0.013). Although the frequency of shivering was higher with granisetron in comparison to tramadol and meperidine, it was not statistically significant (p > 0.05). The number of patients with a shivering score of 2, 3 and 4 was significantly higher in group P compared with the other groups (p = 0.001). Both meperidine and tramadol caused a significantly prolonged emergence time (20.58 +/- 3.56 and 16.45 +/- 4.13 minutes, respectively) as opposed to granisetron (13.58 +/- 3.41 minutes) and placebo (12.61 +/- 3.31 minutes). The prophylactic use of granisetron 40 microg/kg is as effective as meperidine (0.4 mg/kg) and tramadol (0.1 mg/kg) in preventing postanesthetic shivering without prolonging the emergence time from anesthesia.

A comparison is made between observations and numerical simulations of magnetic fluctuations near the proton and water group ion cyclotron frequencies as a function of distance from the comets Halley and Giacobini-Zinner. The amplitude of waves due to different cyclotron resonant instabilities is monitored by examining the amplitude of waves near the gyrofrequency of the respective ions, measured in by the ICE spacecraft. The results are compared with a one-dimensional electromagnetic hybrid simulation of two-ion pickup based on the predictions of Gary et al. (1989). The observations are consistent with the prediction that amplitudes are dependent on the properties of the injected beams and the local injection rate.

To compare medical students' skills for vaginal operative delivery by vacuum extraction (VE) after hands-on training versus video demonstration. We randomized medical students to an expert demonstration (group 1) or a hands-on (group 2) training using a standardized VE algorithm on a pelvic training model. Students were tested with a 40-item Objective Structured Assessment of Technical Skills (OSATS) scoring system after training and 4 days later. OSATS scores were the primary outcome. Performance time, self-assessment, confidence, and global rating scale were secondary outcomes. We assessed the constructive validity of OSATS in this VE model comparing metric scores of experts and students. In all, 137 students were randomized. OSATS scores were higher in group 2 (n = 63) compared with group 1 (n = 74) (32.89 ± 6.39 vs 27.51 ± 10.27, respectively; P < 0.0001). Global rating scale (1.49 ± 0.76 vs 2.33 ± 0.94, respectively; P < 0.0001), confidence (2.22 ± 0.75 vs 3.26 ± 0.94, respectively; P = 0.04), self-assessment (2.03 ± 0.62 vs 2.51 ± 0.77, respectively; P < 0.0001), and performance time (38.81 ± 11.58 seconds vs 47.23 ± 17.35 seconds, respectively; P = 0.001) also favored group 2. After 4 days, this effect persisted with OSATS scores still being significantly higher in group 2 (30.00 ± 6.50 vs 25.59 ± 6.09, respectively; P = 0.001). The assessed OSATS scores showed constructive validity. In a multiple linear regression analysis, group assignment independently influenced OSATS scores, whereas sex, handedness, sports activities, and type of curriculum were not independently associated with OSATS scores. Hands-on training is superior to video demonstration for teaching VE on a pelvic model.

Physical and Psychologic Effects of Aromatherapy Inhalation on Pregnant Women: A Randomized Controlled Trial

PubMed Central

2013-01-01

Abstract Objectives Stress reduction care is important for pregnant women to decrease obstetric complications and children's health problems after birth. The aim of this study is to clarify the physical and psychologic effects of inhalation aromatherapy on pregnant women. Essential oils with high linalool and linalyl acetate content that may be used during pregnancy were selected and among these, and the one preferred by the participant was used. Design This was a prospective, randomized, controlled trial. Settings/location This trial was performed at a gynecology outpatient department in a hospital in Kyoto, Japan. Participants The study included pregnant women in week 28 of a single pregnancy with a normal course. Interventions Participants were randomly assigned into an aromatherapy group and a control group. They were seated in the resting, seated position for 10 minutes. During the latter 5 minutes of each 10-minute session, aromatherapy inhalation was performed for the aromatherapy group. Outcome measures Before and after the intervention, the Profile of Mood States (POMS) was measured. During the trial, the heart-rate fluctuations were measured for the autonomic nervous system regulation. Results A total of 13 pregnant women participated in the trial. Seven (7) participants were assigned to the aromatherapy group and 6 participants to the control group. The results of the POMS were such that based on an intragroup comparison, significant differences were observed in the Tension-Anxiety score (p<0.05) and the Anger-Hostility score (p<0.05), and the respective improvements observed were due to aromatherapy. The results of the autonomic nervous system regulation were such that based on an intragroup comparison within the aromatherapy group, the parasympathetic nerve activity increased significantly (p<0.05). Conclusions Aromatherapy inhalation using essential oils containing linalyl acetate and linalool was found to be effective for the POMS and parasympathetic nerve activity, based on an intragroup comparison. However, based on a comparison between the groups, no substantial difference was observed; hence, further study is necessary in the future. PMID:23410527

To analyze the retinal radial peripapillary capillary (RPC) network in normal-tension glaucoma (NTG) and nonarteritic anterior ischemic optic neuropathy (NAION) eyes using optical coherence tomography angiography (OCTA). Twenty-two patients with NTG, 22 patients with unilateral chronic NAION, and 23 age-matched controls were enrolled. Patients underwent OCTA to obtain en face angiograms of the peripapillary region. The main outcome measures were as follows: (1) the whole en face image perfusion density (WPD) and (2) the circumpapillary perfusion density (CPD). Mean ± SD age was 66.3 ± 7.0 years in the NTG group, 68.1 ± 4.3 years in the NAION group, and 63.9 ± 7.0 years in the control group (p > 0.05 for all the comparisons). The visual field mean defect (MD) was worse in patients than in controls (p < 0.0001), but did not differ between NTG and NAION (-9.6 ± 2.6 dB and -8.2 ± 2.6 dB, respectively). The WPD was 0.41 ± 0.04 in the NTG group (p < 0.0001 in comparison with healthy subjects and NAION patients), 0.46 ± 0.04 in the NAION group (p < 0.0001 in comparison with the control group), and 0.56 ± 0.03 in the control group. The CPD was significantly reduced in both NTG (0.48 ± 0.04, p < 0.0001) and NAION eyes (0.52 ± 0.05, p < 0.0001), after comparison to control eyes (0.59 ± 0.03). Moreover, the CPD was significantly lower in NTG than in NAION eyes (p = 0.006). OCTA documented a reduction of the peripapillary perfusion in NTG and unilateral NAION. In presence of similar functional damage, the lower perfusion densities in NTG may indicate greater vascular alterations in chronic compared to acute ischemic optic neuropathies.

AIM: To evaluate the effects of different types of dietary fats on the hepatic lipid content and oxidative stress parameters in rat liver with experimental non-alcoholic fatty liver disease (NAFLD). METHODS: A total of 32 Sprague-Dawley rats were randomly divided into five groups. The rats in the control group (n = 8) were on chow diet (Group 1), rats (n = 6) on methionine choline-deficient diet (MCDD) (Group 2), rats (n = 6) on MCDD enriched with olive oil (Group 3), rats (n = 6) on MCDD with fish oil (Group 4) and rats (n = 6) on MCDD with butter fat (Group 5). After 2 mo, blood and liver sections were examined for lipids composition and oxidative stress parameters. RESULTS: The liver weight/rat weight ratio increased in all treatment groups as compared with the control group. Severe fatty liver was seen in MCDD + fish oil and in MCDD + butter fat groups, but not in MCDD and MCDD + olive oil groups. The increase in hepatic triglycerides (TG) levels was blunted by 30% in MCDD + olive oil group (0.59 ± 0.09) compared with MCDD group (0.85 ± 0.04, p < 0.004), by 37% compared with MCDD + fish oil group (0.95 ± 0.07, p < 0.001), and by 33% compared with MCDD + butter group (0.09 ± 0.1, p < 0.01). The increase in serum TG was lowered by 10% in MCDD + olive oil group (0.9 ± 0.07) compared with MCDD group (1.05 ± 0.06). Hepatic cholesterol increased by 15-fold in MCDD group [(0.08 ± 0.02, this increment was blunted by 21% in MCDD + fish oil group (0.09 ± 0.02)]. In comparison with the control group, ratio of long-chain polyunsaturated fatty acids omega-6/omega-3 increased in MCDD + olive oil, MCDD + fish oil and MCDD + butter fat groups by 345-, 30- and 397-fold, respectively. In comparison to MCDD group (1.58 ± 0.08), hepatic MDA contents in MCDD + olive oil (3.3 ± 0.6), MCDD + fish oil (3.0 ± 0.4), and MCDD + butter group (2.9 ± 0.36) were increased by 108%, 91% and 87%, respectively (p < 0.004). Hepatic paraoxonase activity decreased significantly in all treatment groups, mostly with MCDD + olive oil group (-68%). CONCLUSION: Olive oil decreases the accumulation of triglyceride in the liver of rats with NAFLD, but does not provide the greatest antioxidant activity. PMID:17230603

To explore the effect of the demethylation drug 5-Aza-CdR on endometrial carcinoma xenografted in nude mice. Randomly assigned the mice into decitabine (AZA),cisplatin (DDP),medroxyprogesterone acetate (MPA),AZA+DDP,AZA+MPA,DDP+MPA and model groups (three in each group) after building the models of xenografted tumor by transplanting the HEC-1B cells on nude mice,and dealt them respectively with corresponding drugs (1 μg/g,single or combination) in the experiment groups and normal saline in model group (injected per 3 d,8 injections in total).Then the tumor inhibitory rates in different groups were calculated.The methylation and protein expression of RASSF1A gene was estimated by methylation specific PCR (MSP) and Western blot respectively,and apoptosis situation of carcinoma cell was estimated by tunel. Inhibitory rate in AZA+DDP group was the highest,and the lowest was AZA group. RASSF1A gene promoter region methylation levels of AZA,AZA+DDP and AZA+MPA groups significantly reduced and showed obvious demethylation stripes while other groups mainly showed the methylation stripes.The differences of RASSF1A protein expression between AZA,AZA+DDP and AZA+MPA groups were not statistical significant ( P >0.05),but the three were higher than model group ( P <0.05);there was no statistically significant difference respectively in the DDP,MPA,DDP+ MPA groups compared with that of model group ( P >0.05).In the comparison of apoptosis index,model group was the lowest,followed by the three single medicine groups,and the highest was three combination groups ( P <0.05). Demethylation drug 5-Aza-CdR in endometrial cancer treatment has a great potential clinical application value by reversing the abnormal methylation of RASSF1A gene,restoring biological functions of RASSF1A protein and strengthening the efficacy of DDP and MPA.

The purpose of this study was to evaluate the efficiency of a new storage medium, coconut water, in comparison with other traditional storage media like Hank's balanced salt solution (HBBS) and milk, in maintaining the viability of an established cell line BHK-21/C13 (baby hamster kidney fibroblasts) using the direct suspension cell culture technique. The storage media tested in the study were divided into three major groups and two control groups - Group A: HBBS, Group B: milk, and Group C: coconut water. The positive and negative controls corresponded to 0-minute and 24-hour dry times respectively. The three groups were then divided into five subgroups, each denoting the storage time periods 15 min, 30 min, 45 min, 60 min and 120 min respectively. The cell line BHK-21/C13 was subcultured and the number of cells was standardized by making a cell suspension using Minimal Essential Medium in five culture plates. One ml of each experimental group (HBBS, milk and coconut water) was added to eight wells of each culture plate. The culture plates containing the cells and the experimental groups were incubated for the respective time periods. The cells were then counted with a Neubauer counting chamber, under light microscope. The results were statistically analyzed using One-way ANOVA and Multiple Range Test using the Tukey-HSD procedure to identify the significant groups at p ≤ 0.05. Within the parameters of this study, it appears that coconut water may be a better alternative to HBSS or milk, in terms of maintaining cell viability. Coconut water can be used as a superior transport medium for avulsed teeth. PMID:20142880

In the present study insulin (I) and GH secretion was studied in a group of twenty-five young adolescent girls (mean age: 15 +/- 0.23 yr) with cycle irregularity associated to clinical signs of hyperandrogenism in comparison with that observed in eleven normal matched subjects with regular menses. All patients underwent basal hormone measurements and, on two consecutive days, an oral glucose tolerance test (OGTT) and a GHRH iv test. Therefore, all subjects had a transabdominal US scan for the measurement of ovarian volume and the characterization of ovarian morphology. On the basis of the US examination we found patients with polycystic ovaries (PCO-like group) and subjects with multifollicular ovaries (MFO group). PCO-like group exhibited T (p<0.01) and LH (p<0.05) plasma levels higher than control group and the highest free androgen index (FAI) values (13 +/- 0.87). All patients with irregular menses showed plasma concentrations of AUC for I (AUC-I) significantly higher in respect to control group (7359.4 +/- 709 vs 5447 +/- 431 microIU/ml x 180 min, p<0.01) as well as both PCO-like group and MFO group did (p<0.001 and p<0.01) respectively. MFO group showed higher values of the AUC for GH (AUC-GH) (2809 +/- 432 ng/ml x 120 min) in respect to controls (1708 +/- 208 ng/ml x 120 min, p<0.05) and PCO-like subjects (p<0.001), who on the contrary showed the lowest AUC-GH values (618 +/- 119 ng/ml x 120 min). In conclusion, PCO-like patients associated hyperinsulinemia with a blunted GH secretion while MFO patients had higher GH secretion associated with higher AUC-I values in a way suggesting an immature and still developing reproductive system.

PURPOSE: To compare the clinical outcomes and complications between 23-G and 25-G vitrectomy in patients with diabetic vitreous hemorrhage (VH). MATERIALS AND METHODS: A retrospective comparative study comprising 69 eyes (36 eyes in 23-G group and 33 eyes in 25-G group) of 65 patients who underwent vitrectomy with air tamponade for diabetic vitreous hemorrhage (VH) with at least 6 months of follow-up was conducted. RESULTS: There were no significant differences between the two groups in age, gender, bilaterality, type of diabetes, presence of hypertension, lens status, and previous argon laser photocoagulation state (P > 0.05). Best-corrected visual acuity (BCVA) of both groups at postoperative 1 month logarithm of the minimum angle of resolution (logMAR) (1.06 ± 0.99, 0.90 ± 0.96), 3 months logMAR (1.07 ± 0.93, 0.83 ± 0.85), and 6 months logMAR (1.03 ± 0.89, 0.83 ± 0.85) significantly improved from the preoperative BCVA logMAR (2.03 ± 0.83, 2.15 ± 0.99) for 23-G group, 25-G group, respectively (P < 0.0001). There was no significant difference in BCVA between the two groups preoperatively and at 1, 3, and 6 months postoperatively (P = 0.566, 0.506, 0.333, and 0.445, respectively), incidence of intraoperative wound suturing (21.4%, 15.2%), postoperative hypotony (0.0%, 0.0%), early postoperative VH (POVH) (11.1%, 15.2%), late POVH (5.6%, 0.0%), retinal detachment (2.8%, 6.1%), neovascular glaucoma (92.8%, 9.1%), and endophthalmitis (0.0%, 0.0%) for 23-G group, 25-G group, respectively (P > 0.05). CONCLUSION: 25-G vitrectomy is as effective for PDR as 23-G vitrectomy. PMID:29118498

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.

Primary hyperoxaluria-I (PH-I) is a serious metabolic disease resulting in end-stage renal disease. Pre-emptive liver transplantation (PLT) for PH-I is an option for children with early diagnosis. There is still little information on its effect on long-term renal function in this situation. Long-term assessment of renal function was conducted using Schwartz's formula (estimated glomerular filtration rate-eGFR) in four children (Group A) undergoing PLT between 2002 and 2008, and a comparison was done with eight gender- and sex-matched controls (Group B) having liver transplantation for other indications. All patients received a liver graft from a deceased donor. Median follow-up for the two groups was 64 and 94 months, respectively. One child in Group A underwent re-transplantation due to hepatic artery thrombosis, while acute rejection was seen in one. A significant difference was seen in eGFR at transplant (81 vs 148 mL/min/1.73 m(2)) with greater functional impairment seen in the study population. In Group A, renal function reduced by 21 and 11% compared with 37 and 35% in Group B at 12 and 24 months, respectively. At 2 years post-transplantation, there was no significant difference in eGFR between the two groups (72 vs 100 mL/min/1.73 m(2), respectively; P = 0.06). Renal function remains relatively stable following pre-emptive LTx for PH-I. With early diagnosis of PH-I, isolated liver transplantation may prevent progression to end-stage renal disease and the need for renal transplantation.

The purpose of this study is to evaluate the freeze-all strategy in subgroups of normal responders, to assess whether this strategy is beneficial regardless of ovarian response, and to evaluate the possibility of implementing an individualized embryo transfer (iET) based on ovarian response. This was an observational, cohort study performed in a private IVF center. A total of 938 IVF cycles were included in this study. The patients were submitted to controlled ovarian stimulation (COS) with a gonadotropin-releasing hormone (GnRH) antagonist protocol and a cleavage-stage day 3 embryo transfer. We performed a comparison of outcomes between the fresh embryo transfer (n = 523) and the freeze-all cycles (n = 415). The analysis was performed in two subgroups of patients based on the number of retrieved oocytes: Group 1 (4-9 oocytes) and Group 2 (10-15 oocytes). In Group 1 (4-9 retrieved oocytes), the implantation rates (IR) were 17.9 and 20.5% (P = 0.259) in the fresh and freeze-all group, respectively; the ongoing pregnancy rates (OPR) were 31 and 33% (P = 0.577) in the fresh and freeze-all group, respectively. In Group 2 (10-15 oocytes), the IR were 22.1 and 30.1% (P = 0.028) and the OPR were 34 and 47% (P = 0.021) in the fresh and freeze-all groups, respectively. Although the freeze-all policy may be related to better in vitro fertilization (IVF) outcomes in normal responders, these potential advantages decrease with worsening ovarian response. Patients with poorer ovarian response do not benefit from the freeze-all strategy.

We compared outcome and complications of three simple varicocelectomy techniques. Groups were divided according to whether they would receive the Ivanissevich technique (n = 55), Tauber's technique (n = 51) or subinguinal sclerotherapy (n = 49). Selection criteria were: infertility >1 year, subnormal semen, sonographic diameter of veins >3 mm and time of regurge >2 s. Patients were randomly assigned to the groups of treatment, with follow-up every 3 months for 1 year. Improvement was only in sperm count and total motility for all groups. Pregnancy rates were 20, 13.73 and 12.24%, respectively, with no significant difference between groups. Hydrocele occurred only in the group which received the Ivanissevich technique (5.5%). Tauber's technique is simple; however, it has the disadvantage of multiple branching of small veins. Copyright © 2010 S. Karger AG, Basel.

Eight Alu insertions at the NBC27, TPA25, NBC148, NBC123, ACE, APOA1, NBC51, and PV92 locus were examined in three subethnic groups of Kalmyks (Torgouds, Derbets, and Buzava). In general, the pattern of allele frequencies in Kalmyks was consistent with that in Asian populations of the world, and was similar to the Alu insertion frequencies pattern in Turkic populations of the Volga--Ural region and Central Asia. Pairwise comparisons of three subpopulations of Kalmyks with respect to the frequency distributions of eight Alu insertions revealed the differences between the groups examined. The coefficient of gene differentiation, F(st), constituted 1.37%, pointing to the common origin of the groups of interest, as well as to the uniformity of the gene pools of subethnic groups of Kalmyks examined.

We prepared a lotion using electrolytic-reduction ion water (ERI), and evaluated the healing effects of this lotion (ERI lotion) on burn wounds. Third degree burn wounds were induced in the mouse dorsal skin, and ERI lotion or physiological salt (PS) lotion was applied to the wounds from immediately after injury [ERI (+) group and ERI (-) group as a control group, respectively]. The burn wound area was measured, and its serial changes were evaluated. In addition, histological examination of the burn wound site (on day 3) was performed. Comparison of the ERI (+) and (-) groups showed a significant reduction in the burn wound area in the former. Histological examination confirmed many interstitial spaces, blood vessels, and lymphatic vessels in the subcutaneous tissue in the ERI (-) compared with the ERI (+) group. These results suggest the promotion of burn wound healing by ERI lotion.

Whether the combination of obesity and low muscle strength (dynapenic-obesity) would cause greater impairment of the activities of daily living (ADL)/instrumental activities of daily living (IADL) than obesity alone and low muscle strength alone (dynapenia) remains unclear. The aim of this study was to reveal the possible independent and additive effects of dynapenia and obesity on ADL/IADL disability in an older Chinese population. A cross-sectional study, including 616 community-dwelling older adults, was conducted in China from 2010 to 2012. Based on the World Health Organization Asian Criteria of Obesity and handgrip strength tertiles, 4 independent groups were identified as follows: nondynapenia/nonobesity, dynapenia alone, obesity alone, and dynapenic-obesity. The Katz Index of Independence in ADL was used to assess ADL disability, whereas 6 IADL items of the Older Americans Resources and Services (OARS) multidimensional functional assessment questionnaire were used to assess IADL disability. The prevalence of ADL and IADL disability was 21.1% and 28.9% in the dynapenic-obesity group, 15.5% and 22.6% in the dynapenia alone group, 13.1% and 19.6% in the obesity alone group, and 11.9% and 12.9% in the nondynapenia/nonobesity group, respectively. After adjusting for the covariates, in comparison with the dynapenic-obesity group, the adjusted odds ratios (95% confidence interval) for ADL disability were 0.36 (0.13-0.73) in the nondynapenia/nonobesity group, 0.51 (0.20-0.78) in the dynapenia-alone group, and 0.40 (0.11-0.61) in the obesity-alone group. The corresponding data for IADL disability were 0.55 (0.20-0.93), 0.82 (0.39-0.98), and 0.61 (0.30-0.91), respectively. Dynapenia, obesity, and dynapenic-obesity were associated with an increased risk of ADL/IADL disability. Dynapenic-obesity was associated with a greater risk of ADL/IADL disability in comparison with dynapenia or obesity alone. Copyright © 2014 American Medical Directors Association, Inc.

Very little information is available on whether docosahexaenoic acid (DHA) supplementation has a beneficial effect on liver fat and cardiovascular disease (CVD) risk factors in children with nonalcoholic fatty liver disease (NAFLD). In a double-blind, placebo-controlled randomized trial we investigated whether 6-month treatment with DHA improves hepatic fat and other fat depots, and their associated CVD risk factors in children with biopsy-proven NAFLD. Of 58 randomized children, 51 (25 DHA, 26 placebo) completed the study. The main outcome was the change in hepatic fat fraction as estimated by magnetic resonance imaging. Secondary outcomes were changes in visceral adipose tissue (VAT), epicardial adipose tissue (EAT), and left ventricular (LV) function, as well as alanine aminotransferase (ALT), triglycerides, body mass index-standard deviation score (BMI-SDS), and insulin sensitivity. At 6 months, the liver fat was reduced by 53.4% (95% CI, 33.4-73.4) in the DHA group, as compared with 22.6% (6.2-39.0) in the placebo group (P = 0.040 for the comparison between the two groups). Likewise, in the DHA group VAT and EAT were reduced by 7.8% (0-18.3) and 14.2% (0-28.2%), as compared with 2.2% (0-8.1) and 1.7% (0-6.8%) in the placebo group, respectively (P = 0.01 for both comparisons). There were no significant between-group changes for LV function as well as BMI-SDS and ALT, while fasting insulin and triglycerides significantly decreased in the DHA-treated children (P = 0.028 and P = 0.041, respectively). DHA supplementation decreases liver and visceral fat, and ameliorates metabolic abnormalities in children with NAFLD. Copyright © 2015 Elsevier B.V. All rights reserved.

This study examined various psychometric properties of the items comprising the shame and guilt scales of the Test of Self-Conscious Affect-Adolescent (TOSCA-A) in a group children between 8 and 11 years of age. A total of 699 children (367 females and 332 males) completed these scales, and also measures of depression and empathy. Confirmatory factor analysis (CFA) provided support for an oblique two-factor model, with the originally proposed shame and guilt items comprising shame and guilt factors, respectively. There was good internal consistency reliability for the shame and guilt scales, with omega coefficient values of 0.77 and 0.81 for shame and guilt, respectively. Also, shame correlated with depression symptoms positively (0.34, p < 0.001) and had no relation with empathy (-0.07, ns). Guilt correlated with depression symptoms negatively (-0.28, p < 0.001), and with empathy positively (0.13. p < 0.05). Thus there was support for the convergent and discriminant validity of the shame and guilt factors. Multiple-group CFA comparing this group of children with a separate group of adolescents (320 females and 242 males), based on the chi-square difference test, supported full metric invariance, the intercept invariance of 17 of the 30 shame and guilt items, and higher latent mean scores among children for both shame and guilt. The non-equivalency for intercepts and mean scores were of small effect sizes. Comparisons based on the difference in root mean squared error of approximation values supported full measurement invariance and no group difference for latent mean scores. The findings in the current study support the use of the TOSCA-A in children and the valid comparison of scores between children and adolescents, thereby opening up the possibility of evaluating change in the TOSCA-A shame and guilt factors over these developmental age groups.

In the present study, we examined the preventive role of epigallocatechin gallate (EGCG) in an experimental non-alcoholic steatohepatitis model induced by a high fat diet. The study included 21 male Sprague-Dawley rats, which were equally divided into three groups. The first group was fed on a standard rat diet, the second group on a high fat diet (HFD), and the third group on a HFD + EGCG. The study concluded after 6 weeks. Histopathological examination was performed. Plasma and tissue MDA levels, glucose, insulin, alanine aminotransferase (ALT), aspartate aminotransferase, gamma glutamyltransferase, alkaline phosphatase, triglyceride, and cholesterol levels were studied. Insulin resistance was calculated by the homeostasis model of insulin resistance method. Steatosis, inflammation, ballooning degeneration, and necrosis increased significantly in the HFD group, compared to the control group (P < 0.01). Steatosis and inflammation decreased in the HFD + EGCG group, in comparison to the HFD group (P < 0.05, for each). There was a significant decline in ALT (P < 0.01), triglyceride (P < 0.01), insulin (P < 0.05), and glucose (P < 0.05) levels in the HFD + EGCG group, when compared to the HFD group. Plasma and liver MDA levels in the HFD + EGCG group were lower than those of the HFD group; the difference was significant (P < 0.01 for each). Glutathione levels in the HFD + EGCG group was significantly higher those in the HFD group. CYP 2E1 and alpha-smooth muscle actin expression decreased in the HFD + EGCG group, in comparison to the HFD group (P < 0.01, P < 0.05, respectively). EGCG reduces the development of experimental non-alcoholic steatohepatitis induced by a high fat diet. It seems to exercise this effect through its effect on lipid metabolism and antioxidant characteristics.

The aim of this study was to investigate whether PMMA-CHDF in the treatment of a patient with septic acute renal failure (septic ARF) is clinically relevant. Thirteen patients were treated with PMMA-CHDF. Thirteen patients were treated with PAN-CHDF. The urinary output significantly increased in PMMA-CHDF group following 24h of the treatment (p<0.05), whereas those did not improve in PAN-CHDF group. The 28-day survival was 84.6% in PMMA-CHDF group and 38.5% in PAN-CHDF group, respectively (p<0.05). We can assume that the cytokine modulation with PMMA-CHDF in the treatment of patients with septic ARF is clinically relevant.

Health vulnerability refers to a lack of protection for specific population groups with specific health problems, as well as the disadvantages they face in solving them in comparison with other population groups. This major public health problem has multiple and diverse causes, including a shortage of trained health care personnel and the lack of family, social, economic, and institutional support in obtaining care and minimizing health risks. Health vulnerability is a dynamic condition arising from the confluence of multiple social determinants. This article attempts to describe the health situation of three vulnerable groups in Mexico-older adults, indigenous people, and migrants-and, after defining the needs of each, explore measures that could contribute to the design and implementation of public health policies better tailored to their respective needs.

Research indicates that persons with learning disorders often suffer from psychopathology. We assessed current and future psychopathology in male adolescents with discrete impairments in reading comprehension (IRC) or arithmetic abilities (IAA) but with average or above-average general intellectual abilities. Subjects were a population-based cohort of 174,994 male adolescents screened by the Israeli Draft Board with average or above-average intellectual abilities but with low scores (8.6th and 10th lowest percentile respectively) on reading or arithmetic tests. They were compared with adolescents who scored in the 10th percentile and above on these tests (comparison group). Relative to the comparison group, male adolescents with IRC, IAA, or IRC and IAA (0.69%), had poorer scores on most behavioral assessments and higher prevalence of current psychopathology: 4.2% (comparison group), 8.0% (IRC), 7.0% (IAA), and 9.8% (IRC and IAA). Adolescents with IRC were also at increased risk for later hospitalization for schizophrenia (hazard ratios = 1.8, 95% confidence interval: 1.3-2.6). Male adolescents with average and above-average general intellectual abilities but with IRC or IAA are more likely to have current and future psychopathology. Impairments in intellectual functioning and abnormal behaviors leading to mental illnesses may share common neurobiological substrates. The results support screening male adolescents with learning disorders for psychopathology.

Objectives. We used a community-based research approach to test a culturally based breast cancer screening program among low-income Hmong women in central and southern California. Methods. We designed a culturally informed educational program with measures at baseline and 1-year follow-up in 2 intervention cities and 1 comparison city. Measures included changes in breast cancer screening, knowledge, and attitudes. Results. Compared with women in the comparison community, women in the intervention community significantly improved their attitudes toward, and increased their knowledge and receipt of, breast cancer screenings. Odds of women in the intervention group having had a mammogram, having had a clinical breast examination, and having performed breast self-examination was 6.75, 12.16, and 20.06, respectively, compared with women in the comparison group. Conclusions. Culturally informed education materials and intervention design were effective methods in conveying the importance of maintaining and monitoring proper breast health. The strength of community collaboration in survey development and intervention design highlighted the challenges of early detection and screening programs among newer immigrants, who face significant language and cultural barriers to care, and identified promising practices to overcome these health literacy challenges.

To evaluate the association between long-term clinical outcomes and morbidity of patients with prostate cancer who underwent high-intensity focused ultrasound (HIFU). We included 918 patients with stage T1c-T3N0M0 prostate cancer who were treated with Sonablate™ (SB) devices during 1999-2012 and followed-up for >2 years. Risk stratification and complication rates were compared between the treatment groups. The 10-year overall and cancer-specific survival rates were 89.6% and 97.4%, respectively. The 5-year biochemical disease-free survival (bDFS) rates in the SB200/500, SB500 version 4, and SB500 tissue change monitor groups were 48.3%, 62.3%, and 82.0%, respectively (p < 0.0001). In the low-, intermediate-, and high-risk categories, the 10-year bDFS rates for all patients were 63%, 52%, and 32%, respectively (p < 0.0001), whereas the 5-year bDFS rates in the tissue change monitor group were 95%, 84%, and 72%, respectively (p = 0.0134). The overall negative biopsy rate was 87.3%. Multivariate analysis showed pre-treatment serum prostate-specific antigen levels, neoadjuvant hormonal therapy, and devices as significant predictors (p < 0.0001). Urethral stricture, epididymitis, and urinary incontinence were observed in 19.7%, 6.2%, and 2.3% of the cases, respectively. Long-term follow-up with HIFU demonstrated improved clinical outcomes owing to technical, imaging, and technological advancements.

Irreversible pulpitis (IP) commonly results in decreased anesthetic efficacy of the inferior alveolar nerve block (IANB) for mandibular molar. It has been shown that supplementary buccal and/or lingual infiltration as well as premedication with ketorolac result in improved efficacy of the IANB. One hundred fifty emergency patients who had their lower first or/and second molar diagnosed with IP participated in the study. All patients were randomly divided into 2 major IANB groups: 1 group received 4% articaine with 1:100,000 epinephrine, and the other group received 2% lidocaine with 1:80,000 epinephrine. Each group was further divided into 3 subgroups of 25 each: (1) buccal and lingual infiltration with articaine and lidocaine, respectively; (2) preoperative oral medication of ketorolac; and (3) preoperative oral medication of ketorolac followed by buccal and lingual infiltration with articaine and lidocaine, respectively. Endodontic access was initiated 15 minutes after solution deposition, and all patients were required to have profound lip numbness. Success of the anesthetic was defined as none or mild pain on endodontic access and initial instrumentation. Statistical analysis was performed using multiple-comparison analysis of variance (Kruskal-Wallis) and t tests. Articaine IANB with infiltrations plus oral ketorolac premedication significantly increased the success rate to 76%. The success rate after the administration of an articaine IANB with infiltration injections was 64%, whereas with lidocaine it was 32% (P < .05). Premedication with ketorolac significantly increases the anesthetic efficacy of articaine IANB plus infiltration in mandibular molars with IP. Copyright © 2015 American Association of Endodontists.

To make a randomized comparison of 2 consolidation treatment options (two patient groups): 2 cycles of cytarabine in average (Ig/m2 in Group 2) and standard (100 mg/mi2 in Group 1) doses in combination with idarubicin (8-12 mg/m2) and mitoxantrone (10 mg/m2), after two 7+3 induction cycles of daunorubicin (60 mg/mi2) and subsequent 6 cycles of maintenance therapy. In January 2010 to October 2013, a Russian multicenter trial was conducted to treat patients with acute myeloid leukemias (AML) in accordance with the AML-01.10 protocol (ClinicalTrials.gov Identifier: NCT01587430). The trial enrolled 243 AML patients from 21 centers, including 71 patients (median age 38 years) from the State Hematology Center, Ministry of Health of the Russian Federation; 35 and 36 patients were randomized to Groups 1 and 2, respectively. The randomized groups were balanced by basic clinical and laboratory parameters. Favorable, intermediate, and high cytogenetic prognoses were in 14 (21.9%), 40 (62.5%), and 10 (15.6%) patients, respectively. Prior to treatment, 2 patients died; one patient refused treatment. Fifty-eight (85.3%) of the 68 patients achieved complete remission (CR); early deaths was in 2 (2.9%) and resistance in 8 (11.8%). Four (6.9%) patients died during CR. Protocol deviations (doses, intervals, and the number of cycles) were recorded in 12 (20.7%) of the 58 patients. Other 8 (11.8%) patients were switched to low-dose cytarabine because of complications, withdrawn from the protocol and not included into the analysis of randomized comparison. Twenty allogeneic bone marrow transplantations (allo-BMT) (7 related, 12 unrelated, and 1 haploidentical) were performed; of them 15 allo-BMTs were done during first CR. In the 68 patients, 3-year overall survival (OS) was 45.6%; relapse-free survival (RFS) was 41.5%. OS was 64.6% in Group 1 and 58.3% in Group 2; RFS was 62 and 38.8% in Groups 1 and 2, respectively (p>0.5). In the favorable, intermediate, and high prognosis groups, OS was 79.5, 60, and 31.1% and RFS was 81.8, 41.3, and 33.3%, respectively (p=0.1). The consolidation treatment option unchanged survival rates in the above risk groups. Unachieved CR after the first cycle considerably decreased RFS (33.9% versus 60%) and served as an indication for allo-BMT during first CP (RFS without BMT was 0; that with BMT was 78%). No differences were found between both consolidation options according to long-term results. Protocol deviations were recorded in one-third of the patients. While implementing the protocol, the efficiency of treatment was high. Allo-BMT during first CR substantially increased RFS if CP was not achieved after the first cycle.

This study investigated the effect of extracts of different composites, glass ionomer cement (GIC)s and compomers on the viability of brine shrimp larvae. Ethanolic extracts of four dental composites (Z-100; Solitaire 2; Filtek P60 and Synergy), a conventional GIC (Ketac-Fil), a resin-modified glass ionomer cement (Vitremer), two compomers (F2000; Dyract AP), and a flowable compomer (Dyract Flow) were prepared from each material. Following evaporation of the ethanol, the extracts were resuspended in distilled water, which was then used to test the effects on the viability of brine shrimp larvae. For the composites, the extract of Synergy was the least toxic (88% viability) followed by the extracts of Solitaire 2, Z100 and P60 (75%, 67.5% and 50% viability, respectively). One-way ANOVA revealed highly significant differences between the resin composite materials (p<0.001). Follow-up comparison between the composite groups by Tukey's pairwise multiple-comparison test (α =0.05) showed that the extract of Synergy was significantly less toxic than the extracts of all the other materials except that of Solitaire 2. The compomers showed 100% lethality, while the percentage of viable larvae for the extracts of Ketac-Fil, and Vitremer were 32.3%, and 37.0%, respectively. One-way ANOVA revealed highly significant differences between the groups of materials (p<0.001). Follow-up comparison between the groups by Tukey's test (α = 0.05) showed that the toxic effect of the extracts of the compomers were significantly greater than that of Ketac-Fil, and Vitremer. The differences in the toxic effects of Vitremer and Ketac-Fil were not statistically significant. In conclusion, the toxicity of composite materials varied according to their chemical composition. Compomers were the most lethal materials to brine shrimp larvae followed by GICs and then composites. PMID:19089264

This study compared ankle range of motion (AROM) including dorsiflexion, plantar flexion, inversion and eversion, and venous refill time (VRT) in leg skin inflamed by venous disorders, before and after a new cryotherapy ulcer prevention treatment. Fifty-seven-individuals participated in the randomized clinical trial; 28 in the experimental group and 29 received usual care only. Results revealed no statistically significant differences between the experimental and usual care groups although AROM measures in the experimental group showed a consistent, non-clinically relevant decrease compared to the usual care group except for dorsiflexion. Within treatment group comparisons of VRT results showed a statistically significant increase in both dorsiflexion and plantar flexion for patients with severe VRT in the experimental group (6.9 ± 6.8; p = 0.002 and 5.8 ± 12.6; p = 0.02, respectively). Cryotherapy did not further restrict already compromised AROM, and in some cases, there were minor improvements. PMID:23516043

In a reference-controlled double-blind trial in patients with acute pharyngitis the effects of a newly developed lozenge containing 8 mg of benzocaine (p-aminobenzoic acid ethyl ester, CAS 94-09-7) were compared with those of an identically dosed commercial pastille. 246 patients were randomized to receive either the lozenges (group A, n = 123) or the pastilles (group B, n = 123). Each patient took a total of six doses within 12 h according to the double-dummy principle, with each single dose spaced by 2 h. The primary parameter was the assessment of the responder rate with = 50 % pain relief within 15 min post application. Further parameters included the relative relief of pain in the course of the study and the tolerability of the formulation. After application of the first unit the comparison of groups yielded very similar and statistically not differing results for efficacy in both groups, with responder rates of 25.2 % and 22.0 % in groups A and B, respectively. One adverse drug reaction was observed in group B (burning and tingling feeling on the tongue), which, however, did not lead to discontinuation of study participation. In all other cases tolerability was stated to be "good to very good". The application of the benzocaine lozenges was statistically non-inferior to the use of the pastilles.

Background: Ferrous sulfate is the most used supplement for treating anemia, but it can result in unfavorable side effects. Nowadays, nanotechnology is used as a way to increase bioavailability and decrease the side effects of drugs and nutrients. This study investigates the effects of nanoparticles containing iron on blood and inflammatory markers in comparison to ferrous sulfate in anemic rats. Methods: To induce the model of hemolytic anemia, 50 mg/kg bw phenylhydrazine was injected intraperitoneally in rats on the 1st day and 25 mg/kg bw for the four following days. Then, rats were randomly divided into five groups. No material was added to the nipple of the Group 1 (control). Group 2 received 0.4 mg/day nanoparticles of iron; Group 3 received 0.4 mg/day ferrous sulfate, and Groups 4 and 5 received double dose of iron nanoparticle and ferrous sulfate, respectively for ten days. Results: Hemoglobin and red blood cell (RBC) in Group 2 were significantly higher than Group 3 (P < 0.05). In addition, hemoglobin and RBC in Group 4 and 5 were significantly higher than Group 3 (P < 0.05). The average level of serum iron in Groups 2 and 4 was remarkably more than the groups received ferrous sulfate with similar doses (P < 0.05). C-reactive protein in Group 3 was more than Group 2 and in Group 5 was more compare to all other groups. Conclusions: Single dose of nanoparticles had more bioavailability compare to ferrous sulfate, but this did not occur for the double dose. Furthermore, both doses of nanoparticles caused lower inflammation than ferrous sulfate. PMID:27857830

Background Few studies have evaluated the effectiveness of massage for back pain. Objective To evaluate the effectiveness of two types of massage for chronic back pain. Design Single-blind parallel group randomized controlled trial. Setting Integrated health care delivery system in Seattle area. Patients 401 persons 20 to 65 years of age with non-specific chronic low back pain. Interventions Ten treatments over 10 weeks of Structural Massage (intended to identify and alleviate musculoskeletal contributors to pain through focused soft-tissue manipulation) (n=132) or Relaxation Massage (intended to decrease pain and dysfunction by inducing relaxation) (n=136). Treatments provided by 27 experienced licensed massage therapists. Comparison group received continued usual care (n=133). Study presented as comparison of usual care with two types of massage. Measurements Primary outcomes were the Roland Disability Questionnaire (RDQ) and the Symptom Bothersomeness scale measured at 10 weeks. Outcomes also measured after 26 and 52 weeks. Results At 10 weeks, the massage groups had similar functional outcomes that were superior to those for usual care. The adjusted mean RDQ scores were 2.9 and 2.4 points lower for the relaxation and structural massage groups, respectively, compared to usual care (95% CIs: [1.8, 4.0] and [1.4, 3.5]). Adjusted mean symptom bothersomeness scores were 1.7 points and 1.4 points lower with relaxation and structural massage, respectively, versus usual care (95% CIs: [1.2, 2.2] and [0.8, 1.9]). The beneficial effects of relaxation massage on function (but not on symptom reduction) persisted at 52 weeks, but were small. Limitations Restricted to single site; therapists and patients not blinded to treatment. Conclusions This study confirms the results of smaller trials that massage is an effective treatment for chronic back pain with benefits lasting at least 6 months, and also finds no evidence of a clinically-meaningful difference in the effectiveness of two distinct types of massage.

Children in northern Uganda have undergone significant psychosocial stress during the region's lengthy conflict. A Psychosocial Structured Activities (PSSA) program was implemented in 21 schools identified as amongst those most severely affected by conflict-induced displacement across Gulu and Amuru Districts. The PSSA intervention comprised a series of 15 class sessions designed to progressively increase children's resilience through structured activities involving drama, movement, music and art (with additional components addressing parental support and community involvement). Eight schools were selected by random quota sampling from those schools receiving the PSSA intervention. Two hundred and three children were identified in these schools as being scheduled to receive intervention, and were followed up 12 months later following engagement with PSSA activities. A comparison group comprised 200 children selected from schools that had met inclusion criteria for receipt of intervention, but were not scheduled for intervention coverage until later. Preliminary research used participatory focus group methodology to determine local indicators of child well-being as viewed by parents, teachers, and children respectively. Pre- and post- assessments focused on ratings for each child - by parents, teachers and children - with respect to these indicators. Significant increases in ratings of child well-being were observed in both intervention and comparison groups over a 12-month period. However, the well-being of children who had received the PSSA intervention increased significantly more than for children in the comparison group, as judged by child and parent (but not teacher) report. This effect was evident despite considerable loss-to-follow-up at post-testing as a result of return of many households to communities of origin. General improvement in child well-being over a 12-month period suggests that recovery and reconstruction efforts in Northern Uganda following the onset of peace had a substantive impact on the lives of children. However, exposure to the PSSA program had an additional positive impact on child well-being, suggesting its value in post-conflict recovery contexts. © 2011 The Authors.

The objective of this prospective RCT was to compare the efficacy of a web-based teaching tool to traditional didactic teaching in IVF patients. Forty women undergoing their first IVF cycle were randomly allocated to an interactive web-based teaching session or a nurse-led didactic teaching session. The primary outcome measure was participant knowledge regarding the IVF process, risks, and logistics assessed before and after the respective teaching session. Secondary outcomes included patient stress, assessed before and after the respective teaching session, and patient satisfaction, assessed following the respective teaching session and on the day of embryo transfer (following implementation of the teaching protocol). Both groups demonstrated similar and significant improvements in knowledge and stress after exposure to their respective teaching sessions. The web-based group was significantly more satisfied than the didactic teaching group. Web-based teaching was also shown to be equally effective for participants of high versus low income and education status for knowledge, stress, and satisfaction. This study provides preliminary support for the use of web-based teaching as an equally effective tool for increasing knowledge and reducing stress compared to traditional didactic teaching in IVF patients, with the added benefit of increased patient satisfaction.

The quality of cartilage repair after marrow stimulation is unpredictable. To overcome the shortcomings of the microfracture technique, various augmentation techniques have been developed. However, their efficacies remain unclear. The quality of cartilage repair and clinical outcomes would be superior in patients undergoing high tibial osteotomy (HTO) with microfracture and collagen augmentation compared to those undergoing HTO with microfracture alone without collagen augmentation for the treatment of medial compartment osteoarthritis (OA) of the knee. Randomized controlled trial; Level of evidence, 2. Twenty-eight patients undergoing HTO were randomized into 2 groups: microfracture alone (group 1, n = 14) or microfracture with collagen augmentation (group 2, n = 14). At 1 year postoperatively, second-look arthroscopic surgery and biopsy of repaired cartilage were performed at the time of HTO plate removal. Biopsy specimens were graded using the International Cartilage Repair Society Visual Assessment Scale II (ICRS II). In addition, imaging outcomes in terms of the magnetic resonance observation of cartilage repair tissue (MOCART) score were assessed based on magnetic resonance imaging (MRI). Finally, clinical outcomes in terms of the visual analog scale (VAS) for pain score, Knee Injury and Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee (IKDC) score, and Tegner activity scale score were evaluated. The mean ICRS II score in group 2 was significantly higher than that in group 1 (1053.2 vs 885.4, respectively; P = .002). Group 2 showed greater improvement in tissue morphology, cell morphology, surface architecture, middle/deep zone assessment, and overall assessment compared with group 1 ( P < .050 for all comparisons). Imaging outcomes based on the MOCART score were superior in group 2 compared to those in group 1 on MRI at 1 year postoperatively (64.6 vs 45.4, respectively; P = .001). The degree of defect repair was better in group 2 than in group 1 ( P = .040). Clinical outcomes in terms of the VAS for pain score, KOOS, IKDC score, and Tegner activity scale score were improved in both groups without between-group differences ( P > .100 for all comparisons). The quality of cartilage repair after microfracture with collagen augmentation was superior to that after microfracture alone in patients undergoing HTO. Clinical results after 1 year did not reflect this difference in tissue repair. Therefore, a longer follow-up of the cohort is needed to answer this question.

To compare a dose of oral and rectal acetaminophen and to evaluate acceptability of rectal acetaminophen, since oral and rectal acetaminophen is widely used as an antipyretic agent in febrile children and the comparative effectiveness of these two preparations is not well established. In this prospective parallel group designed study, 60 children who presented to the emergency department or outpatient pediatric clinic at a tertiary hospital and aged from 6 months to 6 years with rectal temperature over 39 degrees C were enrolled. Patients were randomly assigned to two equal-sized groups. Group 1 received 15 mg/kg acetaminophen rectally and group 2 received the same dose orally. Temperature was recorded at baseline and 1 and 3 hours after drug administration. In the first group, mean decrease in temperature, 1 and 3 hours after administration of acetaminophen was 1.07+/-0.16 (p < 0.001) and 1.74+/-0.25 degrees C (p < 0.001), respectively, and in the second group it was 1.98+/-0.19 (p < 0.001) and 1.70+/-0.14 degrees C (p < 0.001), respectively (p > 0.05). Rectal and oral acetaminophen preparations have equal antipyretic effectiveness in children. The rectal route proved to be as acceptable as the oral one among parents.

300 adolescents aged 12-15 years were randomised (1:1) into two groups to compare the long-term (10 years) immunogenicity profile of two doses of an Adult formulation [Group HAB_2D: 150; 0-6 months] vs. three doses of a Paediatric formulation [Group HAB_3D: 150; 0-1-6 months] of a combined hepatitis A and B (HAB) vaccine. At Year 10, anti-HAV seropositivity rate was 100% in both groups, while 85.9% and 85.1% subjects in the HAB_2D and HAB_3D groups, respectively, had anti-HBs antibody concentrations > or =10 mIU/mL. The anti-HAV antibody GMCs (HAB_2D: 429.3 mIU/mL; HAB_3D: 335.5 mIU/mL) and anti-HBs antibody GMCs (HAB_2D: 50.6 mIU/mL; HAB_3D: 60.1 mIU/mL) were similar in both groups. No vaccine-related serious adverse events were reported. Hence, with respect to long-term antibody persistence, the two-dose schedule of the combined HAB vaccine Adult formulation is an effective alternative to the conventional three-dose schedule of the Paediatric formulation in adolescents.

The Lightning Imaging Sensor (LIS) aboard the TRMM satellite has been collecting optical lightning data since November 1997. A Lightning Mapping Array (LMA) that senses VHF impulses from lightning was installed in North Alabama in the Fall of 2001. A dataset has been compiled to compare data from both instruments for all times when the LIS was passing over the domain of our LMA. We have algorithms for both instruments to group pixels or point sources into lightning flashes. This study presents the comparison statistics of the flash data output (flash duration, size, and amplitude) from both algorithms. We will present the results of this comparison study and show "point-level" data to explain the differences. AS we head closer to realizing a Global Lightning Mapper (GLM) on GOES-R, better understanding and ground truth of each of these instruments and their respective flash algorithms is needed.

Association of deletion polymorphism in GSTT1 and GSTM1 genes and polymorphic variant A313G of GSTP1 gene with cirrhosis diseases and 4-year survival rate for the Tomsk region (West Siberia) patients were tested. Homozygous deletion of GSTM1 gene (null genotype) was a protective factor for alcoholic and mixed (HCV, HBV and alcohol) liver cirrhosis development. The patients from the joint group (all etiology forms) as well as having alcoholic and mixed cirrhosis had lower frequency of GSTM1 null genotype (39.2, 39.0, and 34.2%, respectively) in comparison with the control group (64.6%). The GSTM1 null genotype and GSTP1 gene A313G polymorphic variant correlated with the patients' survival rate. The patients survived in comparison with the dead had higher frequency of a GSTM1 null genotype (46.6 vs. 30.2%) and GSTP1 AA genotype (63.1 vs. 40.5%), and lower frequency of GSTP1 AG (A313G) genotype (31.1 vs. 51.2%). A survival rate was 2.5 times higher for patients having GSTP1 AA genotype in comparison with the GG and AG genotype carriers and 2 times higher for patients having GSTM1 null genotype than the gene carriers. A 4-year fatal case probability was 2.3 times higher among the patients having heterozygous AG GSTP1 genotype in comparison with homozygous AA and GG genotype carriers.

Purpose : To investigate whether there is a difference between symptoms of floaters according to the type of ophthalmic viscosurgical devices(OVDs) used during phacoemulsification. Methods: A total of 112 eyes had undergone standard phacosurgery with the dispersive OVDs(Group1). Group2 comprised 117 eyes that underwent phacosurgery with the dispersive OVDs, but between continuous curvilinear capsulorhexis and hydrodissection, some OVDs had been removed. Group3 included 120 eyes that had undergone phacosurgery with the cohesive OVDs. Results: 14 eyes (12.5%) of Group1 had new-onset floater after surgery whereas 6 eyes (5.13%) in Group2, and 7 eyes (5.83%) in Group3 at the day after and a week after surgery. This was significantly higher in Group1 than Group2 and Group3, respectively (p=0.047,0.049). Conclusion: Cataract surgery with dispersive OVD can predispose the eye to an increased floater symptom. Therefore, surgeons should consider release some OVDs during hydrodissection with dispersive viscoelastics and keep trying to avoid IOP surge during surgery.

Objective. To determine the degree to which 3 different educational interventions enhance cultural competency in pharmacy students. Methods. Students were equally divided among a simulated-patient activity group, a written case-scenarios group, and a formal lecture group. Mean scores for pre- and post-intervention cultural self-assessment surveys were compared. Results. In the simulation group, there were significant positive changes in the cultural skills and cultural desire components; in the case-scenario group, there was a significant positive change in the cultural awareness component; and in the lecture group, there were significant positive changes in the cultural skills and cultural empathy components. With respect to the cultural skills component, there was greater post-intervention improvement in the simulation and lecture groups than in the case-scenario group. Conclusions. There were significant positive changes within each group, indicating that ideologies and behaviors may be altered based on the educational intervention received. However, a 1-hour practicum may not be sufficient to enhance cultural competency. PMID:23716744

Understanding corneal biomechanical responses during long-term glucocorticosteroids administration is important in clinical practice. The purpose of this study is to investigate the biomechanical influence of fluorometholone 0.1% eye drops on rabbit cornea. Thirty-eight Japanese white rabbits were randomly divided into three groups; a fluorometholone group, a supernatant group and a blank control group. For each rabbit in fluorometholone group, one cornea was treated with fluorometholone 0.1% eye drops four times a day for 8 weeks, while corneas of rabbits in supernatant group were treated in the same frequency with supernatant fraction centrifuged from fluorometholone 0.1% eye drops. The rabbits in the blank control group were not given any treatment. At the end of the 8 week observation period, the rabbits were euthanized and the eyes immediately enucleated and prepared for inflation testing. The experimental pressure-deformation data was used to derive the stress-strain behavior of each eye using an inverse modeling procedure. Comparisons of mechanical stiffness of corneas were conducted among the three groups to determine the influence of fluorometholone. The results showed that corneal stiffness decreased as the fluorometholone administration time prolonged. Comparisons of tangent modulus indicated average stiffness reductions of 34.2% and 33.5% in the fluorometholone group compared to the supernatant and control groups, respectively, at the end of the observation period. The stiffness-reduction effect of fluorometholone on the cornea should be considered in clinical management, especially when administrating it to biomechanically weakened corneas, such as after refractive surgeries and in cases of keratoconus. © 2013 Published by Elsevier Ltd.

Liver resection is the treatment option with the best chance for cure in patients with malignant liver tumors. However, there are concerns regarding postoperative recovery in elderly patients, which may lead to a preference of non-resectional therapies over hepatectomy in this patient population. Although laparoscopic liver resection (LLR) is associated with a faster recovery compared to open hepatectomy, there are scant data on how elderly patients tolerate LLR. The aim of this study was to analyze the perioperative outcomes of LLR in elderly patients with hepatic malignancies, with a comparison to laparoscopic RFA (LRFA). A retrospective analysis of a prospective database for liver tumors identified a total of 82 patients older than 65 years who underwent laparoscopic treatment of their liver tumors in a single tertiary care center between 2000 and 2014. These patients were equally distributed into LLR and LRFA treatment arms. Mean age, American Society of Anesthesiologists (ASA) score and tumor type (predominantly metastatic colorectal cancer) were similar in both groups. Patients in the LRFA group had more tumors (2.1 ± 1.8 vs. 1.2 ± 0.6, p < 0.01), whereas tumors were larger in the LLR group (3.8 ± 1.6 vs. 2.8 ± 1.1 cm, p < 0.01). Although the operative time (116 vs. 214 min, p < 0.01) and hospital stay (2.1 vs. 3.4 days, p = 0.010) were shorter for the LRFA versus LLR group, respectively, morbidity (4.8 vs. 7.3 %) and mortality (0 vs. 0 %) were similar. Local recurrence was significantly higher in the LRFA versus LLR group (29 vs. 2.4 %, respectively, p = 0.002). However, there was no statistical difference in disease-free and overall survival between two groups (28 vs. 30 and 51 vs. 54 months, p = 0.443 and 0.768, respectively). This study showed that LLR was tolerated as well as LRFA in elderly patients with similar comorbidities. We suggest LLR to be considered as an option in selected elderly patients who are deemed poor candidates for open hepatectomy.

Background: Burns are known as one of the most common and destructive forms of injury with a vast spectrum of consequences. Despite the discovery of various antibacterial and antiseptic agents, burn wound healing still has remained a challenge to modern medicine. Plants, with a valuable traditional support, have been considered as potential agents for prevention and treatment of disorders in recent years. However, modern scientific methods should be applied to validate the claims about the therapeutic effects of the herbal products. Objectives: This study was conducted to evaluate the wound-healing activity of a poly herbal cream (PHC), retrieved from Iranian Traditional Medicine (ITM), in a rat burn wound model in Iran. Materials and Methods: In this experimental study, PHC containing aqueous extracts of Malva sylvestris and Solanum nigrum leaves and oily extract of Rosa damascena petals was used. Second-degree burn wounds were induced in four groups of five rats each. Group 1 received no treatment while groups 2, 3 and 4 were given cream base, silver sulfadiazine (SS) 1% and PHC, respectively to compare the efficacy of PHC with the negative and positive control groups. The percentage of wound healing on days 2, 6, 10 and 14 and histopathological parameters of healed wounds on the 14th day were assessed. Antioxidant and antimicrobial activities of PHC were evaluated using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and micro-dilution methods, respectively. Results: There was a significant improvement in healing percentage of PHC-treated rats in comparison to the other groups at the end of the treatment period (87.0% ± 2.1% for PHC in comparison to 32.2% ± 1.6%, 57.0% ± 5.3% and 70.8% ± 3.5% for the control, cream base and SS groups, respectively). Moreover, the healed wounds in PHC-treated animals contained less inflammatory cells and had desirable re-epithelialization with remarkable neovascularization. In addition to the antioxidant activity, PHC exhibited antibacterial effect against Staphylococcus aureus. Conclusions: Poly herbal cream experimentally and histopathologically revealed a burn wound healing activity probably due to the antioxidant, anti-inflammatory and antimicrobial activities of its phytochemical contents. Therefore, this study confirms the use of M. sylvestris, S. nigrum and R. damascena in burn prescriptions in ITM. PMID:26473072

Introduction: The aim of this in vitro study is to evaluate the role of light and laser sources in the bleaching ability of 37.5% H2 O2 on extracted human teeth. Materials and Methods: About 30 caries-free single-rooted maxillary central incisors were used for the study. Specimens were prepared by sectioning the crown portion of teeth mesiodistally, and labial surface was used for the study. Specimens were then immersed in coffee solution for staining. Color of each tooth was analyzed using Shadestar, a digital shademeter. Specimens were then divided into three groups of 10 each and were subjected to bleaching with 37.5% H2 O2, 37.5% H2 O2 + light activation, and 37.5% H2 O2 + laser activation, respectively. Postbleaching, the color was analyzed for all the specimens immediately and then after 1, 2, and 3 weeks intervals, respectively. Results: All the statistical analyses were done using SPSS version 17. Intra- and inter-group comparisons were done with Friedman test and Kruskal–Wallis ANOVA, respectively. Statistical analysis concluded with a significant improvement in their shade values from baseline in all the three groups. Halogen light activation and laser-activated groups showed comparatively enhanced bleaching results over no-activation group, though the difference was not statistically significant. Conclusion: The results of the present study show that bleaching assisted with halogen light and laser showed increased lightness than nonlight activated group. Durability of bleaching results obtained postbleaching was maintained throughout the experimental trail period of 3 weeks for both halogen light and laser activation group, whereas no-light activation group presented with shade rebound after 2 weeks postbleaching.

Purpose To compare the visual outcomes between PRK-MMC and phakic IOL in patients with more than 8 diopter (D) of myopia. Methods This comparative study was performed on 23 eyes under treatment with Artiflex (group A) and 23 eyes under treatment with PRK-MMC (group B). Artiflex phakic IOL (Ophtec BV) was used in group A, and the VISX STAR S4 Excimer Laser (Abbott) was used for PRK-MMC in group B. Results The safety index was 1.11±0.23 and 1.05±0.25 (P=0.100) and the efficacy index was 1.02±0.11 and 0.98±0.10 (P=0.266) in group A and B, respectively. At 1 year after surgery, the manifest refraction spherical equivalent was −0.17±1.18 and −0.25±0.18 D in group A and B, respectively (P=0.471). Mesopic CS showed no significant difference between the two groups in any spatial frequency. Total coma was 0.24±0.17 and 0.67±0.40 μm (P<0.001), spherical aberration was −0.11±0.11 and 0.41±0.18 μm (P<0.001), and RMS HOAT was 0.50±0.20 and 0.96±0.45 μm (P<0.001) in group A and B, respectively. Conclusion Phakic IOL implantation was better than PRK-MMC in the correction of high myopia in terms of visual quality, but the two methods had no difference with regard to visual acuity. Therefore, PRK-MMC can be used when the anterior chamber depth is a limiting factor in the implantation of phakic IOLs. PMID:24993326

Background This study compared the results of patients treated for ulnar impaction syndrome using an ulnar shortening osteotomy (USO) alone with those treated with combined arthroscopic debridement and USO. Methods The results of 27 wrists were reviewed retrospectively. They were divided into three groups: group A (USO alone, 10 cases), group B (combined arthroscopic debridement and USO, 9 cases), and group C (arthroscopic triangular fibrocartilage complex [TFCC] debridement alone, 8 cases). The wrist function was evaluated using the modified Mayo wrist score, disabilities of the arm, shoulder and hand (DASH) score and Chun and Palmer grading system. Results The modified Mayo wrist score in groups A, B, and C was 74.5 ± 8.9, 73.9 ± 11.6, and 61.3 ± 10.2, respectively (p < 0.05). The DASH score in groups A, B, and C was 15.6 ± 11.8, 19.3 ± 11.9, and 33.2 ± 8.5, respectively (p < 0.05). The average Chun and Palmer grading score in groups A and B was 85.7 ± 8.9 and 84.7 ± 6.7, respectively. The difference in the Mayo wrist score, DASH score and Chun and Palmer grading score between group A and B was not significant (p > 0.05). Conclusions Both USO alone and combined arthroscopic TFCC debridement with USO improved the wrist function and reduced the level of pain in the patients treated for ulnar impaction syndrome. USO alone may be the preferred method of treatment in patients if the torn flap of TFCC is not unstable. PMID:21909465

To compare the therapeutic effects of subject-chosen and therapist-chosen activities in occupational therapy for inpatients with chronic schizophrenia. Prospective comparative study. A psychiatric hospital in Japan. Fifty-nine patients with chronic schizophrenia who had been hospitalized for many years. The subjects received six-months occupational therapy, participating in either activities of their choice (subject-chosen activity group, n = 30) or activities chosen by occupational therapists based on treatment recommendations and patient consent (therapist-chosen activity group, n = 29). The Positive and Negative Syndrome Scale and the Global Assessment of Functioning (GAF) Scale were used to evaluate psychiatric symptoms and psychosocial function, respectively. After six-months occupational therapy, suspiciousness and hostility scores of the positive scale and preoccupation scores of the general psychopathology scale significantly improved in the subject-chosen activity group compared with the therapist-chosen activity group, with 2(2) (median (interquartile range)) and 3(1.25), 2(1) and 2.5(1), and 2(1) and 3(1), respectively. There were no significant differences in psychosocial functions between the two groups. In within-group comparisons before and after occupational therapy, suspiciousness scores of the positive scale, preoccupation scores of the general psychopathology scale, and psychosocial function significantly improved only in the subject-chosen activity group, with 3(1) to 2(2), 3(1) to 2(1), and 40(9) to 40(16) respectively, but not in the therapist-chosen activity group. The results suggested that the subject-chosen activities in occupational therapy could improve the psychiatric symptoms, suspiciousness, and preoccupation of the inpatients with chronic schizophrenia.

Prior studies have reported that the presence of prior biliary stent may interfere with EUS visualization of pancreatic tumors. We aimed to compare the influence of the biliary plastic and fully covered self-expanding metal stents (CSEMS) on the accuracy of EUS-FNA cytology in patients with solid pancreatic masses. We conducted a retrospective study evaluating 677 patients with solid pancreatic head/uncinate lesions and a previous biliary stent in whom EUS-FNA was performed. The patients were stratified into two groups: (1) those with a plastic stents and (2) those with CSEMS. Performance characteristics of EUS-FNA including the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were compared between the two groups. The frequency of obtaining an adequate cytology by EUS-FNA was similar in both the CSEMS group and the plastic stent group (97 vs. 97.1 % respectively; p = 1.0). The sensitivity, specificity, and accuracy of EUS-FNA was not significantly different between patients with CSEMS and plastic stents (96.8, 100, 100 % and 97.3, 98, 99.8 %, respectively). The negative predictive value for EUS-FNA was lower in the CSEMS group compared to the plastic stent group (66.6 vs. 78.1 % respectively; p = 0.42). There was one false-positive cytology in the plastic stent group compared to none in the CSEMS group. In a retrospective cohort trial, EUS-FNA was found to be highly accurate and safe in diagnosing patients with suspected pancreatic cancer, even in the presence of a plastic or metallic biliary stent. The presence of a stent did not contribute to a higher false-positive cytology rate.

Our aim is to compare mammographic, demographic and clinicopathological characteristics of patients whose mammographies were classified as subgroups of BI-RADS 4 category (Breast Imaging - Reporting and Data System). In total, 103 patients with mammography (Senographe 600t Senix HF; General Electric, Moulineaux, France) results classified as BI-RADS 4 were included in the study. Demographic data (age, menopause, and family history) were recorded. All data were compared among BI-RADS 4 subgroups. In all, 68.9% (71/103), 7.8% (8/103) and 23.3% (24/103) the patients were in groups BI-RADS 4A, 4B and 4C, respectively. The incidence of malignancy was higher in Groups 4B and 4C than in Group 4A (p<0.05), but similar in Groups 4B and 4C (p>0.05). Mean age was lower in Group 4B than in Groups 4A and 4C (p<0.05). A positive family history was more common in Group 4A than in Group 4B (p=0.025). The frequency of menopausal patients was greater in Groups 4A and 4C than in Group 4B (p=0.021, and 0.003, respectively). The rate of malignancy was higher in Groups 4B, and 4C than in Group 4A. A positive family history was more common in Group 4A than in Group 4C. Groups 4A, and 4C patients tended to be older and were more likely to be menopausal than Group 4B patients.

The purpose of the present study was to compare the size and configuration of the ablation zones created by SuperSlim and CoAccess electrodes, using various ablation algorithms in ex vivo bovine liver and in clinical cases. In the experimental study, we ablated explanted bovine liver using 2 types of electrodes and 4 ablation algorithms (combinations of incremental power supply, stepwise expansion and additional low-power ablation) and evaluated the ablation area and time. In the clinical study, we compared the ablation volume and the shape of the ablation zone between both electrodes in 23 hepatocellular carcinoma (HCC) cases with the best algorithm (incremental power supply, stepwise expansion and additional low-power ablation) as derived from the experimental study. In the experimental study, the ablation area and time by the CoAccess electrode were significantly greater compared to those by the SuperSlim electrode for the single-step (algorithm 1, p=0.0209 and 0.0325, respectively) and stepwise expansion algorithms (algorithm 2, p=0.0002 and <0.0001, respectively; algorithm 3, p= 0.006 and 0.0407, respectively). However, differences were not significant for the additional low-power ablation algorithm. In the clinical study, the ablation volume and time in the CoAccess group were significantly larger and longer, respectively, compared to those in the SuperSlim group (p=0.0242 and 0.009, respectively). Round ablation zones were acquired in 91.7% of the CoAccess group, while irregular ablation zones were obtained in 45.5% of the SuperSlim group (p=0.0428). In conclusion, the CoAccess electrode achieves larger and more uniform ablation zones compared with the SuperSlim electrode, though it requires longer ablation times in experimental and clinical studies.

This randomized clinical trial (October 2012-December 2013) compared extracorporeal shock wave therapy (ESWT) and a vacuum erectile device (VED) for management of erectile dysfunction (ED). Consecutive Chinese patients (20-55 years) with ED, abnormal nocturnal penile tumescence and rigidity (NPTR), and international index of erectile function-5 items (IIEF-5) score <22 were randomized to receive ESWT or VED (twice weekly, 4 weeks). Primary outcomes were treatment efficacy and success rate 4 weeks after completion of therapy. Secondary outcomes included changes in IIEF-5 score, sex encounter profile (SEP) score, erection hardness score (EHS) and NPTR assessments 4 weeks post-therapy. All enrolled patients (n = 30 per group) completed the study. At baseline, age, IIEF-5 score, SEP score, EHS, and NPTR assessments were similar between groups. Four weeks post-therapy, IIEF-5 score increased in the ESWT (15.03 ± 3.00 vs. 11.60 ± 2.28) and VED (15.10 ± 3.06 vs. 11.53 ± 2.27) groups, as did SEP score, EHS, and NPTR measures (all P < .05). Efficacy in the ESWT and VED groups was excellent in 10% and 13.3%, respectively, and moderate in 63.3% and 53.3%, respectively. Treatment success rate in the ESWT and VED groups was 73.3% and 67.7%, respectively. VED use and ESWT have comparable efficacies in the treatment of ED in Chinese patients.

Of the 50 procedures, 25 each were performed using single and double suture anchors by 1 surgeon. The Karlsson scale had improved significantly to 89.8 points and 90.6 points in the single and double anchor groups, respectively. Using the Sefton grading system, 23 cases (92%) in the single anchor group and 22 (88%) in the double anchor group achieved satisfactory results. The talar tilt angle and anterior talar translation on stress radiographs using the Telos device had improved significantly to an average of 5.7° and 4.6 mm in the single anchor group and 4.5° and 4.3 mm in the double anchor group, respectively. The double anchor technique was superior with respect to the postoperative talar tilt. The single and double suture anchor techniques produced similar clinical and functional outcomes, with the exception of talar tilt as a reference of mechanical stability. The modified Brostrom procedure using both single and double suture anchors appears to be an effective treatment method for chronic lateral ankle instability.

This study assessed a curriculum for bedside ultrasound (US) and compared outcomes from 2 common training pathways. The program consisted of e-learning paired with expert-led hands-on training administered to pulmonary/critical care and cardiology fellows with no prior formal training in bedside US. This "simulation-based learner" group completed a survey of attitudes and confidence before and after training, and knowledge and skills were assessed after training. The surveys and scores of the simulation-based learners were compared to the scores of "experts," who were US-trained emergency physicians, and "apprentice learners," who were intensivist physicians informally trained in bedside US on the job during fellowships. There was a significant difference in the self-reported level of prior training between the groups (simulation-based learners, 2.8; apprentice learners, 3.7; experts, 4.1, on a scale of 1-5 [P= .02]) but no difference in the interest level or perceived importance of bedside US. The study curriculum was successful, as shown by scores that exceeded the comparison groups in the cardiac and pulmonary courses (cardiac: simulation-based learners, 80%; apprentice learners, 73%; experts, 62% [P= .001]; pulmonary: 84%, 75%, and 72%, respectively [P =.02]). The simulation-based learners gained confidence in skills, whereas the comparison groups lost confidence after testing (P < .005); however, the simulation-based learners gained confidence in US subject areas that were not taught (abdomen [P <.002] and miscellaneous [P =.005]). The simulation-based learner curriculum resulted in comparable or greater knowledge and confidence in each area of US versus the comparison groups. Findings of overgeneralization of confidence highlight the importance of quality assurance and supervision in bedside US training programs. © 2015 by the American Institute of Ultrasound in Medicine.

The use of propofol, as compared to barbiturates (e.g. thiopental), for short surgical procedures has been associated with more rapid recovery from the procedure. Propofol, an intravenous anesthetic drug, is frequently used as an adjunct to transvaginal oocyte retrieval but little is known about its effects upon fertilization, embryo development, and pregnancy rate when used drug the for induction of general anesthesia. This study was conducted to compare the outcome of assisted reproductive technology (ART) with the use of propofol versus thiopental sodium for the induction of general anesthesia during oocyte retrieval. In this retrospective study, 92 cases of infertile patients who underwent oocyte retrieval under the induction of general anesthesia with, respectively, either propofol (Group I, 72 cases) or thiopental sodium (Group II, 20 cases) were compared for fertilization rate, cleavage rate, and pregnancy rate. The fertilization rate was 68.9% for Group I and 66.7% for group II (p = 0.614). The cleavage rate was 96.5% for Group I and 94.8% for Group II (p = 0.294). The rate of good embryo grading and poor embryo grading was, respectively, 85.1% and 14.9% for Group I, versus 85.7% and 14.3% for Group II (p = 0.887). The pregnancy rate was 30.5% for Group I and 20.0% for Group II (p = 0.354). The implantation rate and abortion rate was, respectively, 9.1% and 18.2% for Group I versus 7.2% and 25.0% for Group II (implantation rate, p = 0.590; abortion rate, p = 0.600). There were no significant differences between these two groups for fertilization rate, cleavage rate, pregnancy rate, implantation rate and abortion rate. We suggest cautious use of propofol for the procedure of oocyte retrieval despite its associated more rapid post-operative recovery including less nausea/vomiting.

The effects of a 47-week diet of butter or safflower oil as fat in combination with casein or soy protein as protein were observed for the serum concentrations of lipids and fatty acid compositions in rat serum and heart. Serum total cholesterol (Chol) did not differ among the four experimental diet groups. In the butter groups, significantly higher low-density lipoprotein (LDL)-Chol and lower high-density lipoprotein (HDL)-Chol were observed than in the safflower oil groups (p<0.005, respectively). Higher levels of α-tocopherol were found in the butter groups than in the safflower oil groups (p<0.05) and in the casein groups than in the soy protein groups (p<0.01). In comparison with the safflower oil groups, the butter groups showed higher n-3 polyunsaturated fatty acids (PUFA) contents and lower n-6 PUFA contents in serum and the hearts (p<0.005). The ratios of n-3/n-6 PUFA in the butter groups in serum, 0.26 and 0.18, and in the hearts, 0.37 and 0.36, (butter-casein diet and butter-soy protein diet, respectively) were higher than those of the safflower oil groups of under 0.01 in serum and 0.02 and 0.03 in the hearts (safflower oil-casein diet and safflower oil-soy protein diet, respectively) (p<0.005). In the soy protein groups, higher n-3 PUFA contents in the hearts were found than those of the casein groups (p<0.05). This study suggested that the butter diet induces higher levels of n-3 PUFA and a higher n-3/n-6 PUFA ratio than the safflower oil diet in rat serum and hearts over a long feeding period.

There is currently inadequate evidence on the efficacy of surgical decompression for Chiari malformation type I (CM1) in different age groups of patients. In this study, we compared postoperative outcomes across 3 different age groups using the Chicago Chiari Outcome Scale (CCOS). A total of 144 patients who underwent Chiari decompression at our institution between 2008 and 2014 were divided into 3 groups: group A, children age 0-18 years; group B, younger adults age 19-40 years; and group C, older adults, age 41+ years. Patient outcomes were assigned a numerical value based on the CCOS and subjected to statistical analysis. Direct comparisons were made across the 3 age groups. The mean overall score was 14.0 over a mean follow-up of 27.2 months. All 3 groups demonstrated clinical improvement following Chiari decompression; however, group A demonstrated significantly better postoperative improvements than groups B and C in total CCOS scores (7.8% and 12.2%, respectively; P < 0.001) and all the component scores except complications. Group B was not significantly different from group C in total score or any of the component scores. There was a logarithmic relationship between age and outcome (R 2  = 0.64), in which the outcome scores experienced an initial decline with increasing age but leveled off by early adulthood. A direct comparison among the age groups revealed a negative age effect on surgical decompression outcomes in CM1 patients. Children performed significantly better than younger and older adults. This finding supports early surgical intervention for symptomatic pediatric patients to achieve long-term surgical benefit. Copyright © 2017 The Authors. Published by Elsevier Inc.

A sample of 50 men was chosen at random from the population of asbestos insulators in Belfast and matched with a control series of men of similar occupational group with respect to age, height, and smoking habit. Significantly more of the insulators complained of cough and sputum and had basal rales on examination. Clubbing was assessed by means of measurements of the hyponychial angle of both index fingers. These angles were significantly greater in the group of insulators. Twenty-one insulators had ϰ-rays which showed pleural calcification with or without pulmonary fibrosis; one control ϰ-ray showed pulmonary fibrosis. The insulators had no evidence of airways obstruction but static lung volume was reduced and their arterial oxygen tension was lower than that of the controls and their alveolar-arterial oxygen gradient was greater.

The Integration of Emotions in Memories: Cognitive-Emotional Distinctiveness and Posttraumatic Stress Disorder

PubMed Central

Boals, Adriel; Rubin, David C.

2013-01-01

The current study examined cognitive-emotional distinctiveness (CED), the extent to which emotions are linked with event information, in memories associated with PTSD. Participants either with PTSD (n=68) or without PTSD (n=40) completed a modified multidimensional scaling technique to measure CED for their most negative and most positive events. The results revealed that participants in the PTSD group evidenced significantly lower levels of CED. This group difference remained significant when we limited the analysis to traumatic events that led to a PTSD diagnosis (n=33) in comparison to control participants who nominated a traumatic event that did not result in PTSD (n=32). Replicating previous findings, CED levels were higher in memories of negative events, in comparison to positive events. These results provide empirical evidence that memories associated with PTSD do contain special organizational features with respect to the links between emotions and memory. Implications for understanding and treating PTSD are discussed. PMID:23436960

Supporting early mother-infant relationships to ensure infants' future health has been recommended. The aim of this study was to investigate whether video feedback using the Marte Meo method promotes a healthy early relationship between infants and vulnerable first-time mothers. Video feedback or usual care was delivered by health visitors during home visits in Danish municipalities. This quasi-experimental study included pre- and post-tests of 278 vulnerable families. Mothers were allocated to an intervention group (n = 69), a comparison group (n = 209) and an exactly matched video subsample from the comparison group (n = 63). Data consisted of self-reported questionnaires and video recordings of mother-infant interactions. Outcomes were mother-infant dyadic synchrony (CARE-Index), maternal confidence (KPCS), parental stress (PSS), maternal mood (EPDS) and infant socialemotional behaviours (ASQ:SE). The data were analysed using descriptive and linear multiple regression analysis. The levels of dyadic synchrony in the intervention group had significantly improved (p < 0.001) at follow-up with a mean score of 9.51 (95%CI;8.93-10.09) compared with 7.62 (95%CI;7.03-8.21). The intervention group also showed a higher level of maternal sensitivity with a mean score of 9.55 (95%CI;8.96-10.14) compared with 7.83 (95%CI;7.19-8.46) in the matched video subsample (p < 0.001). With respect to infant cooperation, similar improvements were found with a mean score of 9.43 (95% CI;8.88-9.99) in the intervention group compared with 7.73 (95%CI;7.13-8.33) in the matched video subsample from the comparison group (p < 0.001). Furthermore, mothers in the intervention group reported significantly lower levels of parental stress with a mean score of 32.04 (95%CI;30.13-33.94) compared with 35.29 (95%CI;34.07-36.52) in the comparison group (p = 0.03), as well as higher levels of maternal confidence with a mean score of 41.10 (95%CI;40.22-41.98) compared with 40.10 (95%CI;39.65-40.56) in the comparison group (p = 0.04). No significant differences were found in EPDS and ASQ:SE. The findings support the assumption that video feedback using the Marte Meo method early after birth may strengthen the relationship between infants and vulnerable firsttime mothers as well as improve maternal psychosocial functioning. Further research applying random assignment is needed to strengthen these conclusions; further research is also needed to assess any long term effects of the video feedback intervention using the Marte Meo method.

To observe the effect of electroacupuncture (EA) on bispectral index (BIS) and plasma beta-endorphin (beta-EP) level in patients undergoing colonoscopy. Sixty patients were equally randomized into EA group and control group with 30 cases in each. EA (2 Hz/100 Hz, 4-6 V) was applied to the right Zusanli (ST 36) and Shangjuxu (ST 37), and the left Yinlingquan (SP 9), Sanyinjiao (SP 6) and bilateral Hegu (LI 4) respectively 30 min before colonoscopy. The mean arterial pressure (MAP), heart rate (HR) and BIS in two groups were continuously monitored during the study. Plasma beta-EP concentration was detected by radioimmunoassay. The patient's adverse reactions (including pain, satisfaction degree, etc.) were evaluated by visual analog scale (VAS) and verbal stress scale (VSS). Self-comparison showed that MAP and HR in control group increased significantly during colonoscope's splenic flexure passing (P<0.05). Whereas the 2 indexes in EA group had no significant changes during colonoscope insertion, and its splenic flexure passing, hepatic flexure passing and post-enteroscopy (P>0.05). Comparison between two groups showed that MAP at the time-point of colonoscope insertion, and HR at the time-point of colonoscope's splenic flexure passing in EA group were significantly lower than those in control group (P<0.05). BIS values of EA group were significantly lower than those of control group at different time-points after colonoscope insertion (P<0.01). Plasma beta-EP concentrations at the time-points of colonoscope's hepatic flexure passing and post-enteroscopy were evidently increased in both groups in comparison with pre-enteroscopy (P<0.01), and beta-EP was significantly lower in EA group than that in control group at the time-point of colonoscope's hepatic flexure passing (P<0.05). The dosage of Midazolam used for conscious-sedation and the scores of VAS and VSS were also considerably lower in EA group than those in control group (P<0.05, P<0.01). No significant differences were found between two groups in the adverse reactions as dizziness, nausea, vomiting and abdominal pain, but the patients' satisfaction degree in EA group was evidently higher than that in control group (P<0.05). Acupuncture analgesia can effectively lower the colonoscopy patients' BIS value and plasma beta-EP level, meaning attenuation of the patients' stress responses during colonoscopy after EA.

The aim of this study was to compare the fixation rigidity of anterior, anterosuperior, and superior plates in the treatment of comminuted midshaft clavicle fractures. Six-hole titanium alloy plates were produced according to anatomic features of fourth-generation artificial clavicle models for anterior (group I; n = 14), anterosuperior (group II; n = 14), and superior (group III; n = 14) fixation. After plate fixation, 5-mm segments were resected from the middle third of each clavicle to create comminuted fracture models. Half the models from each group were tested under rotational forces; the other half were tested under 3-point bending forces. Failure modes, stiffness values, and failure loads were recorded. All models fractured at the level of the distalmost screw during the failure torque, whereas several failure modes were observed in 3-point bending tests. The mean stiffness values of groups I to III were 636 ± 78, 767 ± 72, and 745 ± 214 N ∙ mm/deg (P = .171), respectively, for the torsional tests and 38 ± 5, 20 ± 3, and 13 ± 2 N/mm, respectively, for the bending tests (P < .001 for group I vs. groups II and III; P = .015 for group II vs. group III). The mean failure torque values of groups I to III were 8248 ± 2325, 12,638 ± 1749, and 10,643 ± 1838 N ∙ mm (P = .02 for group I vs. II), respectively, and the mean failure loads were 409 ± 81, 360 ± 122, and 271 ± 87 N, respectively (P = .108). In the surgical treatment of comminuted midshaft clavicle fractures, the fixation strength of anterosuperior plating was greater than that of anterior plating under rotational forces and similar to that of superior plating.

Effect of Hand Antisepsis Agent Selection and Population Characteristics on Surgical Site Infection Pathogens.

PubMed

Oriel, Brad S; Chen, Qi; Wong, Kevin; Itani, Kamal M F

Selection of a pre-operative hand antisepsis agent has not been studied in relation to surgical site infection (SSI) culture data. In our hospital, we introduced an alcohol-based hand rub (ABR) in 2012 as an alternative to traditional aqueous surgical scrubs (TSS). It was the goal of this study to review any effect of this implementation on SSI pathogen characteristics. In addition, we sought to compare our SSI culture data with available National Healthcare Safety Network (NHSN) data. We hypothesized that SSI pathogens and resistant isolates are affected by surgical hand antisepsis technique. Data collected prospectively between 2007 and 2014 were retrospectively analyzed for two time periods at the Veterans Affairs Boston Healthcare System (VABHS): Before ABR implementation (TSS group) and after (ABR group). Pathogen distribution and pathogenic isolate resistance profiles were compared for TSS and ABR, and similar comparisons, along with procedure-associated SSI comparisons, were made between VABHS and NHSN. All VABHS data were interpreted and categorized according to NHSN definitions. Compared with TSS (n = 4,051), ABR (n = 2,293) had a greater rate of Staphylococcus aureus (42.6% vs. 38.0%), Escherichia coli (12.8% vs. 9.9%), Pseudomonas aeruginosa (8.5% vs. 2.8%), and Enterobacter spp. (10.6% vs. 2.8%), and a lower rate of Klebsiella pneumoniae/K. oxytoca (4.3% vs. 8.5%) cultured from superficial and deep SSIs (p < 0.05). Of the S. aureus isolates, 35.0% and 44.4% were resistant to oxacillin/methicillin (MRSA) in ABR and TSS, respectively (p = 0.06). Looking at all SSIs, coagulase-negative staphylococci and K. pneumoniae/K. oxytoca at VABHS (4.0% and 10.4%, respectively) accounted for the biggest difference from NHSN (11.7% and 4.0%, respectively). Aside from MRSA, where there was no difference between VABHS and NHSN (42.9% vs. 43.7%, respectively; p = 0.87), statistically significant (p < 0.05) differences were observed among multi-drug-resistant K. pneumoniae/K. oxytoca (0% vs. 6.8%, respectively) and Escherichia coli (10.0% vs. 1.6%, respectively), as well as among extended-spectrum cephalosporin-resistant K. pneumoniae/K. oxytoca (4.8% vs. 13.2%, respectively) and Enterobacter (58.3% vs. 27.7%, respectively). VABHS had a greater proportion of SSIs in abdominal and vascular cases than did NHSN (48.6% vs. 22.5% and 13.2% vs. 1.5%, respectively). Overall, these differences were significant (p < 0.05). The TSS and ABR groups differed in the distribution of pathogens recovered. Those differences, along with SSI pathogen distribution, pathogenic isolate resistance profiles, and procedure-associated SSIs between VABHS and NHSN, warrant further investigation.

The objective of this study was to evaluate the effect of various dosages of testosterone (T) delivered in a sustained manner by means of tricalcium phosphate-lysine (TCPL) delivery system on morphological changes of prostatic tissue using adult male rats as a model. In this experiment, adult male rats (250-300 g BW) were randomly divided into five equal groups (n = 8). Rats in group I, II, and III were castrated and implanted subcutaneously with TCPL loaded with three different dosages (10, 100 and 200 mg T, respectively) of T. Rats in group IV were castrated and implanted with sharm TCPL capsules, and rats in group V served as intact unimplanted controls. Surgical aseptic techniques were performed according to standard laboratory procedures. At the end of 4 and 12 weeks post implantation, four animals from each group were sacrificed and the prostate tissues were collected, weighted, and embedded for histo-pathological evaluations. Data collected from this study have shown that exogenous intake of T delivered in a sustained manner for twelve weeks induced several pathophysiological conditions in ventral prostatic tissue in comparison to the control and sham operated groups. This phenomenon was found to be directly proportional to the dose or the level of sustained delivery. The results demonstrated that the use of 10 mg filled TCPL implants decreased the total mass weight of ventral prostate. Light microscopic evaluation of this group (Group I) revealed a cellular adaptation through an atrophy in the epithelium component. Cytopathological observations such as low cuboidal and thin glands, pleomorphism, and occasional presence of connective tissue stroma were detected. In contrast, ventral prostate collected from animals implanted with TCPL filled with 200 mg T (Group III) showed a significant increase in weights of the wet prostatic tissues in comparison to all groups. Histopathological evaluations demonstrated the following. (i) prostatic hypertrophy alone, or in conjunction with hyperplasia of the epithelial cells, (ii) less connective tissue stroma in comparison to the control group, (iii) occasional involvement of mitotic figures, and (iv) increased angiogenesis. No significant change was observed in those animals implanted with TCPL capsules containing 100 mg T compared to the intact control animals.

Disciplinary attitudes and cigarette smoking: a comparison of two schools.

Porter, A

1982-01-01

Two British boarding schools for boys with different disciplinary policies in respect of cigarette smoking were identified. Questionnaires were sent to the young "old boys" of each school to determine their present smoking habit and most were returned (school A 81%, school B 83%). Significantly more responders smoked who had been to the less strict school (school A 39%, school B 30%, p less than 0.05). These figures probably underestimate the smoking prevalence in the two complete groups. The results suggest that measures that reduce the exposure of an uncommitted adolescent to peer group smoking decrease the chances of tobacco dependence in adulthood. PMID:6816346

2008-07-01

The aim of these experiments was to compare conventional, microscopic methods of evaluating pigeon sperm motility and concentration to those measured by computer-assisted sperm analysis (CASA system). Semen was collected twice a week from two groups of pigeons, each of 40 males (group I: meat-type breed; group II: fancy pigeon) using the lumbo-sacral and cloacal region massage method. Ejaculates collected in each group were diluted 1:100 in BPSE solution and divided into two equal samples. One sample was examined subjectively by microscope and the second one was analysed using CASA system. The sperm concentration was measured by CASA using the anti-collision (AC) system and fluorescent staining (IDENT). There were not any significant differences between the methods of evaluation of sperm concentration. High positive correlations in both groups were observed between the sperm concentration estimated by Thom counting chamber and AC (r=0.87 and r=0.91, respectively), and between the sperm concentration evaluated by Thom counting chamber and IDENT (r=0.85 and r=0.90, respectively). The mean values for CASA measurement of proportion of motile spermatozoa (MOT) and progressive movement (PMOT) were significantly lower than the values estimated subjectively in both groups of pigeons (p< or =0.05 and p< or =0.01, respectively). Positive correlations in MOT and PMOT were noted between both methods of evaluation. The CASA system is very rapid, objective and sensitive method in detecting subtle motility characteristics as well as sperm concentration and is recommended for future research into pigeon semen.

Teen motherhood and long-term health consequences.

Patel, Payal H; Sen, Bisakha

The objective of this article is to examine the association of teen motherhood and long-term physical and mental health outcomes. The physical and mental health components (PCS and MCS) of the SF-12 Healthy Survey in the NLSY79 health module were used to assess long-term health outcomes of women who experienced teenage motherhood. Various familial, demographic, and environmental characteristics were indentified and controlled for that may have predicted teen motherhood and long-term health outcomes. The two comparison groups for teen mothers were women who experienced teen-pregnancy only and women who were engaged in unprotected sexual activity as a teenage but did not experience pregnancy. Multivariate ordinary least squares regression was used for analysis. The average PCS and MCS for teen mothers was 49.91 and 50.89, respectively. Teen mothers exhibited poorer physical health later in life compared to all women as well as the comparison groups. When controlling for age, teen mothers had significantly lower PCS and MCS scores compared to all other women. Furthermore, when controlling for familial, demographic, and environmental characteristics, teen mothers exhibited significantly lower PCS and MCS scores. When comparing teen mothers to the two comparison groups, PCS was not statistically different although MCS was significantly lower in the teen-pregnancy group. Teen motherhood does lead to poorer physical health outcomes later in life. On the other hand, poorer mental health outcomes in later life may be attributed to the unmeasured factors leading to a teen pregnancy and not teen motherhood itself. Additional research needs to be conducted on the long-term consequences of teen motherhood.

2012-02-01

To compare quantitatively the results obtained after hemihypoglossal nerve transposition and microvascular gracilis transfer associated with a cross facial nerve graft (CFNG) for reanimation of a paralysed face, 66 patients underwent hemihypoglossal transposition (n = 25) or microvascular gracilis transfer and CFNG (n = 41). The commissural displacement (CD) and commissural contraction velocity (CCV) in the two groups were compared using the system known as Facial clima. There was no inter-group variability between the groups (p > 0.10) in either variable. However, intra-group variability was detected between the affected and healthy side in the transposition group (p = 0.036 and p = 0.017, respectively). The transfer group had greater symmetry in displacement of the commissure (CD) and commissural contraction velocity (CCV) than the transposition group and patients were more satisfied. However, the transposition group had correct symmetry at rest but more asymmetry of CCV and CD when smiling.

To compare the initial costs of the three most established treatments for clinically localized prostate cancer according to risk, age and comorbidity groups, from the healthcare provider's perspective. We carried out a cost comparison study in a sample of patients consecutively recruited between 2003 and 2005 from a functional unit for prostate cancer treatment in Catalonia (Spain). The use of services up to 6 months after the treatment start date was obtained from hospital databases and direct costs were estimated by micro-cost calculation. Information on the clinical characteristics of patients and treatments was collected prospectively. Costs were compared by using nonparametric tests comparing medians (Kruskall-Wallis) and a semi-logarithmic multiple regression model. Among the 398 patients included, the cost difference among treatments was statistically significant: medians were € 3,229.10, € 5,369.00 and € 6,265.60, respectively, for the groups of patients treated with external 3D conformal radiotherapy, brachytherapy and radical retropublic prostatectomy, (p<0.001). In the multivariate analysis (adjusted R(2)=0.8), the average costs of brachytherapy and external radiotherapy were significantly lower than that of prostatectomy (coefficient -0.212 and -0.729, respectively). Radical prostatectomy proved to be the most expensive treatment option. Overall, the estimated costs in our study were lower than those published elsewhere. Most of the costs were explained by the therapeutic option and neither comorbidity nor risk groups showed an effect on total costs independent of treatment. Copyright © 2010 SESPAS.

Background: Shivering is a common complication of general and epidural anesthesia. Warming methods and many drugs are used for control of shivering in the recovery room. The present study is a randomized clinical trial aimed to investigate the effects of two interventions in comparison with pethidine which is the routine treatment on shivering in patients undergoing abdominal surgery with general anesthesia. Materials and Methods: Eighty-seven patients undergoing abdominal surgery by general anesthesia were randomly assigned to three groups (two intervention groups in comparison with pethidine as routine). Patients in warmed intravenous fluids group received pre-warmed Ringer serum (38°C), patients in combined warming group received pre-warmed Ringer serum (38°C) accompanied by humid-warm oxygen, and patients in pethidine group received intravenous pethidine routinely. The elapsed time of shivering and some hemodynamic parameters of the participants were assessed for 20 min postoperatively in the recovery room. Then the collected data were analyzed by software SPSS (v. 16) with the significance level being P < 0.05. Results: The mean of elapsed time in the warmed intravenous serum group, the combined warming group, and the pethidine group were 7 (1.5) min, 6 (1.5) min, and 2.8 (0.7) min, respectively, which was statistically significant (P < 0.05). The body temperatures in both combined warming and pethidine groups were increased significantly (P < 0.05). Conclusions: Combined warming can be effective in controlling postoperative shivering and body temperature increase. PMID:26793258

Natural honey (NH) and Nigella sativa (NS) seeds have been in use as a natural remedy for over thousands of years in various parts of the world. The aim of this study was to assess the protective effects of NS (Nigella sativa) and NH (natural honey) on acetylsalicylic acid induced gastric ulcer in an experimental model with comparison to Cimetidine (CD). Experimental, case control study. Pharmacology and Pathology Department of King Edward Medical University, Lahore, from June to August 2007. The study was conducted on 100 male albino rats, divided into 5 groups, with 20 animals in each group. Group A was used as a control and treated with Gum Tragacanth (GT). Eighty animals of the other groups were given acetylsalicylic acid (0.2 gm/kg body weight for 3 days) to produce ulcers by gavage. Two animals from each group were sacrificed for the detection of gastric ulcers. The remaining 72 animals were equally divided in four groups (B, C, D and E). The rats in group B, C and D were given NS, NH, and CD respectively while those in E were kept as such. No gastric lesions were seen in control group A while all the animals in group E revealed gastric ulcers. The animals of group B, C and D showed healing effects in 15/18 (83%), 14/18 (78%) and 17/18 (94%) animals grossly; 13/18 (72%), 14/18 (78%) and 16/18 (89%) rats showed recovery on microscopic examination respectively. The healing effects were almost the same in all three groups therefore, the statistical difference was not significant among them (p =0.40 and 0.65) while significant from group E (p=0.0000075, 0.0000016 and 0.0000012 respectively). NS and NH are equally effective in healing of gastric ulcer similar to cimetidine. Further broad spectrum studies as well as clinical trials should be conducted before the use of these products as routine medicines.

The aim of this study is to compare the pulmonary function after a segmentectomy with that after a lobectomy for small peripheral carcinoma of the lung. Between 1993 and 1996, segmentectomy and lobectomy were performed on 48 and 133 good-risk patients, respectively. Lymph node metastases were detected after the operation in 6 and 24 patients of the segmentectomy and lobectomy groups, respectively. For bias reduction in comparison with a nonrandomized control group, we paired 40 segmentectomy patients with 40 lobectomy patients using nearest available matching method on the estimated propensity score. Twelve months after the operation, the segmentectomy and lobectomy groups had forced vital capacities of 2.67 +/- 0.73 L (mean +/- standard deviation) and 2.57 +/- 0.59 L, which were calculated to be 94.9% +/- 10.6% and 91.0% +/- 13.2% of the preoperative values (P =.14), respectively. The segmentectomy and lobectomy groups had postoperative 1-second forced expiratory volumes of 1.99 +/- 0.63 L and 1.95 +/- 0.49 L, which were calculated to be 93.3% +/- 10.3% and 87.3% +/- 14.0% of the preoperative values, respectively (P =.03). The multiple linear regression analysis showed that the alternative of segmentectomy or lobectomy was not a determinant for postoperative forced vital capacity but did affect postoperative 1-second forced expiratory volume. Pulmonary function after a segmentectomy for a good-risk patient is slightly better than that after a lobectomy. However, segmentectomy should be still the surgical procedure for only poor-risk patients because of the difficulty in excluding patients with metastatic lymph nodes from the candidates for the procedure.

To compare the effects of an inspiratory versus and expiratory muscle-training program on voluntary and reflex peak cough flow in patients with Parkinson disease. A randomized controlled study. Home-based training program. In all, 40 participants with diagnosis of Parkinson's disease were initially recruited in the study and randomly allocated to three study groups. Of them, 31 participants completed the study protocol (control group, n = 10; inspiratory training group, n = 11; and expiratory training group, n = 10) Intervention: The inspiratory and expiratory group performed a home-based inspiratory and expiratory muscle-training program, respectively (five sets of five repetitions). Both groups trained six times a week for two months using a progressively increased resistance. The control group performed expiratory muscle training using the same protocol and a fixed resistance. Spirometric indices, maximum inspiratory pressure, maximum expiratory pressure, and peak cough flow during voluntary and reflex cough were assessed before and at two months after training. The magnitude of increase in maximum expiratory pressure ( d = 1.40) and voluntary peak cough flow ( d = 0.89) was greater for the expiratory muscle-training group in comparison to the control group. Reflex peak cough flow had a moderate effect ( d = 0.27) in the expiratory group in comparison to the control group. Slow vital capacity ( d = 0.13) and forced vital capacity ( d = 0.02) had trivial effects in the expiratory versus the control group. Two months of expiratory muscle-training program was more beneficial than inspiratory muscle-training program for improving maximum expiratory pressure and voluntary peak cough flow in patients with Parkinson's disease.

To investigate the effectiveness of modified percutaneous suture in repairing acute closed Achilles tendon rupture by comparing with conventional open suture. Between January 2006 and October 2009, 50 patients with acute closed Achilles tendon rupture were treated with modified percutaneous suture by making 5 small incisions at both sides of Achilles tendon and zigzag suture (improved group, n=22) and with Kessler suture (conventional group, n=28), respectively. No significant difference was found in gender, age, time from injury to operation between 2 groups (P > 0.05). In improved group, the patients achieved healing of incisions by first intention after operation and no complication occurred; however, incision infection occurred in 1 case, Achilles tendon re-rupture in 1 case, and incision scar contracture in 2 cases in conventional group. The operation time of improved group [(38.7 +/- 6.6) minutes] was significantly shorter (t=-12.29, P=0.00) than that of conventional group [(52.3 +/- 6.9) minutes]; the blood loss of improved group [(4.9 +/- 2.0) mL] was significantly less (t=-25.20, P=0.00) than that of conventional group [(40.7 +/- 7.1) mL]. The patients were followed up 2-3 years (mean, 29.9 months). The American Orthopaedic Foot and Ankle Society (AOFAS) score was 99.6 +/- 1.0 in improved group and was 98.4 +/- 3.0 in conventional group, showing no significant difference between 2 groups (t=1.66, P=0.10). Comparison with conventional open suture, modified percutaneous suture has some advantages, such as easy operation, less complications, rapid recovery of limb function, and so on. Modified percutaneous suture is one of the best choices for the treatment of acute closed Achilles tendon rupture.

Children from the upper socioeconomic group in India currently show a modest positive secular trend in height, accompanied by a high prevalence of obesity. We examined the anthropometric pattern among children from the middle socioeconomic group. A cross-sectional study of anthropometry in 3794 schoolchildren from the middle socioeconomic group in the city of Lucknow, Uttar Pradesh, India. A comparison with the data of a 20-year-old study of children from the upper socioeconomic group showed that the height of boys in our study was at par with or higher than that of boys of the same (Lucknow-Allahabad-Varanasi) region or national data, at all centiles. In contrast, girls in our study were shorter than national data at all centiles and shorter than girls of the same region at the 3rd centile. Children from the middle socioeconomic group did not show the large increase in weight centiles seen in the recent data of the upper socioeconomic group. The values of body mass index at the 85th and 95th percentile at 17 or 18 years of age in girls and boys were 23 and 25 kg/m2, respectively. Obesity was prevalent in 1% of children of the middle socioeconomic group and an additional 5.7% were overweight. Children from the middle socioeconomic group in Lucknow have grown taller than their 20-year-old counterparts from the upper socioeconomic group. Boys have fared better than girls. Children from the middle socioeconomic group in Lucknow are at present spared from the epidemic of obesity. Copyright 2015, NMJI.

Studies on humans with diabetes mellitus showed that the crosstalk between the intestinal microbiota and the host has a key role in controlling the disease. The aim of this study was to evaluate the effects of sodium butyrate and high performance inulin supplementation simultaneously or singly on glycemic status, lipid profile, and glucagon-like peptide 1 level in adults with type 2 diabetes mellitus. Sixty patients were recruited for the study. The participants were randomly allocated, using randomized block procedure, to one of the four treatment groups (A, B, C, or D). Group A received sodium butyrate capsules, group B received inulin supplement powder, group C was exposed to the concomitant use of inulin and sodium butyrate, and group D consumed placebo for 45 consecutive days. Markers of glycemia, lipid profile, and glucagon-like peptide 1 were measured pre- and post-intervention. Dietary supplementation in groups A, B, and C significantly reduced diastolic blood pressure in comparison with the placebo group (p<0.05). Also, intra-group statistical analysis showed that only treatment with sodium butyrate + inulin (group C) significantly reduced fasting blood sugar (p=0.049) and waist to hip ratio (p=0.020). Waist circumference in groups B and C reduced significantly after the intervention (p=0.007 and p=0.011; respectively). The post hoc Tukey tests showed significant increase in glucagon-like peptide 1 concentration in groups A and C in comparison with group D (p<0.05). The results suggest that inulin supplementation may be useful to diabetic patients and these effects could be increased with butyrate supplement. © Georg Thieme Verlag KG Stuttgart · New York.

This study examined the effects of high- vs. moderate-intensity interval training on cardiovascular fitness, leptin levels and ratings of perceived exertion (RPE) in obese female adolescents. Forty-seven participants were randomly assigned to one of three groups receiving either a 1:1 ratio of 15 s of effort comprising moderate-intensity interval training (MIIT at 80% maximal aerobic speed: MAS) or high-intensity interval training (HIIT at 100% MAS), with matched 15 s recovery at 50% MAS, thrice weekly, or a no-training control group. The HIIT and MIIT groups showed improved (p < 0.05) body mass (BM), BMI Z-score, and percentage of body fat (%BF). Only the HIIT group showed decreased waist circumference (WC) (p = 0.017). The effect of exercise on maximal oxygen uptake (VO2max) was significant (p = 0.019, ES = 0.48 and p = 0.010, ES = 0.57, HIIT and MIIT, respectively). The decrease of rate-pressure product (RPP) (p < 0.05, ES = 0.53 and ES = 0.46, HIIT and MIIT, respectively) followed the positive changes in resting heart rate and blood pressures. Blood glucose, insulin level and the homeostasis model assessment index for insulin decreased (p < 0.05) in both training groups. Significant decreases occurred in blood leptin (p = 0.021, ES = 0.67 and p = 0.011, ES = 0.73) and in RPE (p = 0.001, ES = 0.76 and p = 0.017, ES = 0.57) in HIIT and MIIT, respectively. In the post-intervention period, blood leptin was strongly associated with %BF (p < 0.001) and VO2max (p < 0.01) in the HIIT and MIIT groups, respectively, while RPE was strongly associated with BM (p < 0.01) in the HIIT group. The results suggest that high-intensity interval training may produce more positive effects on health determinants in comparison with the same training mode at a moderate intensity.

Sibutramine and metformin are drugs commonly used to obtain weight loss. We aimed to compare the effects of sibutramine alone with that of sibutramine plus metformin combination on weight loss, insulin sensitivity, leptin and C reactive protein in obese women. Seventy obese women were included. After a diet period of month (baseline), each individual was randomly assigned to receive 15 mg sibutramine (sibutramine group; n = 36) or 15 mg sibutramine plus 1,700 mg metformin per day (sibutramine plus metformin group; n = 34) during the next 12 months. Body weight, insulin resistance by the homeostasis model assessment model (HOMA-IR), leptin and C reactive protein were measured at baseline, after 3 months and after 12 months. Mean weight losses in sibutramine and sibutramine plus metformin groups were 5.3 +/- 4.0% (P < 0.001) and 6.8 +/- 3.9% (P < 0.001) after 3 months, and 10.5 +/- 4.4% (P < 0.001) and 15.7 +/- 4.6% (P = 0.007) after 12 months, respectively. HOMA-IR value also decreased in both sibutramine (P = 0.045 and P = 0.002) and sibutramine plus metformin groups (P = 0.04 and P = 0.015) after 3 and 12 months, respectively. Similarly, serum leptin levels decreased in both sibutramine (P = 0.04, P = 0.01) and sibutramine plus metformin groups (P = 0.023, P = 0.025) after 3 and 12 months, respectively. There was also significant reductions in serum C reactive protein levels in both sibutramine (P = 0.045, P = 0.02) and sibutramine plus metformin groups (P = 0.007, P = 0.001) after 3 and 12 months, respectively. These decrements of body weight, HOMA-IR, serum leptin and C reactive protein levels were not statistical significance between these two groups both after 3 and 12 months (P > 0.05). Combination of sibutramine with metformin did not result in any further effects on weight loss, insulin resistance, leptin and C reactive protein levels when compared to sibutramine alone.

To compare the clinic value between dentomaxillary pantomography and periapical radiographs in localization of the impacted teeth. 43 impacted teeth were localized with both dentomaxillary pantomography technique and periapical radiographs with horizontal tube shift which is clinically widely used. And a comparison between the two methods was carried out using Chi square test. Both dentomaxillary pantomography and periapical radiographs with horizontal tube shift can relatively precisely demonstrate the position of the impacted teeth. The percentage of the cases which the image and the result of surgery was consistent in the two methods was 93.02% and 95.35% (P>0.05) respectively. There was no statistical difference between the two groups. Dentomaxillary pantomography can precisely localize the impacted teeth.

To evaluate the biocompatibility of glass ionomer cement (GIC) impregnated with collagen or bioactive glass to BHK-21 fibroblasts in vitro. Mineral Trioxide Aggregate was used as the standard for comparison. Human maxillary central incisors (n = 70) were instrumented with a rotary NiTi system and filled. Following resection of the apical 3mm, root end cavities were prepared and restored with conventional GIC (group 1) or GIC with 0.01%, 0.1% or 1% collagen (groups 2, 3, 4 respectively) or, 10%, 30% or 50% bioactive glass (groups 5, 6, 7 respectively), or Mineral Trioxide Aggregate (group 8). The root slices were incubated in tissue culture plates with BHK-21 fibroblast cell line. Phase contrast and scanning electron microscopes were used to score cell quantity, morphology and cell attachment. The data were statistically analyzed by one way ANOVA with Post Hoc Tukey HSD test (p = 0.05). Group 5 showed the highest scores which was significantly higher than all other groups (p < 0.05) except group 8, with which there was no significant difference (p > 0.05). Glass ionomer cement with 10% bioactive glass showed better adhesion and spreading of cells than glass ionomer cement with 0.01% collagen. The biocompatibility of collagen and bioactive glass was concentration dependent. The addition of bioactive glass improved the biocompatibility of glass ionomer cement to fibroblasts better than addition of collagen.

Response of the West African Dwarf (WAD) goats to two different isolates of Haemonchus contortus, the Red Sokoto (RS) goat isolate (RSHc) and the WAD goat isolate (WADHc) (isolated from WAD goats), was studied by experimental infections of 4-6-month-old male WAD goat kids. Group 1 and Group 2 goats were each infected with 4500 infective larvae (L3) of RSHc and WADHc, respectively. Group 3 animals served as uninfected control. Prepatent period (PPP), faecal egg counts (FEC), worm burden (WB), body weight (BW), packed cell volume (PCV), and body condition score (BCS) were determined. WAD goats infected with RSHc isolate and the ones infected with WADHc isolate had mean PPP of 19.63 ± 0.26 and 19.50 ± 0.19, respectively. Goats infected with WADHc isolate had significantly higher FEC (P = 0.004) and WB (P = 0.001). BW were significantly higher (P = 0.004) both in the controls and in Group 2 goats infected with WADHc isolate than in Group 1 goats infected with the RSHc isolate. BCS of animals in both infected groups dropped significantly (P = 0.001). There was a significant drop in PCV (P = 0.004) of both infected groups in comparison. Both isolates of H. contortus were pathogenic to the host.

To evaluate a training programme aimed at strengthening caregivers' self-esteem and empowering them, and also to study correlations between psychological empowerment and job satisfaction. Structural and psychological empowerment have received increased attention in nursing management, yet few intervention studies on this topic, based on theoretical assumptions, have been conducted in elderly care. Data on self-assessed psychological empowerment and job satisfaction were collected in an intervention (n = 14) and a comparison group (n = 32), before and after the intervention. When compared over time in the respective groups, there were significant improvements in the intervention group regarding the factor criticism (job satisfaction scale). There were no statistically significant differences in the comparison group. Total empowerment and all factors of empowerment correlated positively with total job satisfaction. Six out of eight factors of job satisfaction correlated positively with total empowerment. Caregivers' perception of criticism can improve through an intervention aimed at strengthening their self-esteem and empowering them. Implications for nursing management Intervention focused on psychological empowerment and especially caregivers' communication skills seems to be beneficial for caregivers. Recommendations are to increase the programme's length and scope and to include all staff at the unit. However, these recommendations need to be studied further.

Children of parents with cancer are at risk of developing mental disorders. RESULTS from divorce research also reveal that sibling relationships can protect the mental health of children in difficult times. Does having a sibling help to cope with an oncological disease of a parent and thus act as a protective factor? A group of 271 children were examined in a multicenter study. 54 % made use of the offered psychosocial support. Only children (N = 89) and children with siblings (N = 182) were compared with respect to their mental health (Strength and Difficulties Questionnaire, SDQ, parental and self-assessment). The group comparison between only children and siblings showed no significant differences in the SDQ (assessed by healthy/ill parent). In the self-assessment 2 % of the only children and 9 % of the siblings showed significant results on the SDQ. The group comparison between only children and children with siblings failed to reveal any important differences in mental health. The study indicates that a negative relationship quality (Sibling Relationship Questionnaire, SRQ) is associated with increased problems in the peer group. The existence of a sibling is not per se a protective factor. Only children do not show more signs of emotional stress than children with siblings.

The types of physical exertion undertaken by weightlifters and race walkers markedly differ. This difference should also be reflected in their respective diets. The aim of the study was to investigate and assess the diets of professional weightlifters and race walkers, along with a comparison to the diets of those students studying physical education (PE). Materials and Methods. Subjects were respectively 12 weightlifters, 12 race walkers and 12 physical education students whose body composition and nutrition were determined by weighing the foods that were both eaten and drunk. The study groups showed body differences, which may have arisen through dietary differences. Higher calorie diets were observed for race walkers according to body mass whilst weightlifters showed no difference with the other groups. Dietary intakes of protein, fat, and carbohydrates were however inappropriate for all groups. Vitamin and mineral intakes in weightlifters and students were within tolerable limits, but the rather aggressive taking of supplements by race walkers resulted in standard/recommended consumption levels being greatly exceeded in some cases. The diets of the study groups of weightlifters and race walkers need to be corrected. nutrition in sport, weightlifting, race walking, food supplementation.

This study investigated the effects of malate supplementation on blood acid-base balance and serum lactate levels in a 137-day feedlot experiment with bull calves. Animals were allotted to one of two experimental groups: (1) A control group (no supplementation), and (2) a group receiving a salt of DL-malic acid. Blood pH, pCO2, HCO3-, base excess, serum L-lactate and productivity parameters were evaluated. Our data reveal that under the conditions of the present experiment malate supplementation did not have any significant effect on productivity parameters by comparison with non-supplemented animals. As regards acid-base balance, no significant effects attributable only to malate were observed. In conclusion, the time-course and the overall means of serum L-lactate for both groups in both growing and finishing periods (0.44 +/- 0.04 mmol/l and 0.39 +/- 0.02 mmol/l, respectively, for control animal; and 0.54 +/- 0.03 mmol/l and 0.49 +/- 0.01 mmol/l, respectively, for supplemented animals) suggests that malate does not have any beneficial effects in animals fed a diet of similar characteristics to that given in this study.

Compare the oxygen saturation profiles before discharge of neonates born extremely preterm (<28 weeks), now at term equivalent age, with healthy term neonates and assess the impact of feeding on this profile in each group. We prospectively evaluated and compared the oxygen saturation profile in 15 very low birthweight infants at term equivalent age, ready to be discharged home without any oxygen and 15 term newborns after 48 hours of life. We also evaluated and compared the saturations of these two groups during a one-hour period during and after feeding. Term equivalent preterm and term infants spent median 3% and 0%, respectively, of the time below 90% in a 12-hour saturation-recording period. Term infants spent a median 0.26% and 0.65% of the time in <90% saturation during feed time and no feed time, respectively. In contrast, preterm infants spent significantly more time <90% saturation (3.47% and 3.5% during feed time and no feed time, respectively). Term equivalent preterm infants spent significantly more time in a saturation range <90% compared to term infants. Feeding had little effect on saturation profile overall within each group. ©2015 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

To compare two different biopsy devices for upper tract urothelial carcinoma (UTUC) and evaluate the pathologic result obtained by these devices. From January 2008 to December 2010, 414 ureteroscopies were performed and 504 biopsies were taken for evaluation of UTUC. Two biopsy devices were compared: 2.4F stainless steel flat wire basket and 3F cup biopsy forceps. The effect of the biopsy device on obtaining an adequate pathologic specimen was evaluated using univariate and multivariate binary logistic regression analysis. We also investigated whether tumor grade determination was affected by the biopsy device among patients with a diagnostic biopsy. Diagnosis was successful in 63% and 94% in the forceps and basket groups, respectively (P < 0.0001). Among biopsies with a definite diagnosis of UTUC, specific grade was determined in 80% and 93% in the forceps and basket groups, respectively (P = 0.033). In subgroup analysis of tumors larger than 10 mm in diameter, diagnosis was obtained in 80% and 94% in the forceps and basket groups, respectively (P = 0.037). Cytologic evaluation was found to increase diagnostic rates. The stainless steel flat wire basket was shown to be superior to the 3F cup biopsy forceps in terms of obtaining tissue diagnosis and providing specific grade.

The proportion of obese patients undergoing coronary artery bypass graft (CABG) surgery is increasing. In this study, our main objective was to assess the effect of obesity on long-term mortality and changes in quality of life (QoL) after GABG. Data of 508 patients who underwent isolated GABG were prospectively collected. RAND-36 Health Survey (RAND-36) was used as an indicator of QoL. BMI was used to assess obesity, and the analysis was based primarily on two patient groups: BMI less than 30 kg/m (408 patients) and BMI of at least 30 (100 patients). All assessments were made preoperatively and repeated 1 and 12 years after CABG surgery. The follow-up of the cohort was complete in 95 and 84% of the alive patients at 1 and 12 years, respectively. Thirty-day, 1-year, and 10-year survival rates were 99.0, 97.0, and 78.0%, respectively, in the obese and 98.0, 96.8, and 79.2%, respectively, in the nonobese group. Obese showed significant (P<0.05) improvements only in four and nonobese in seven of eight RAND-36 dimensions of QoL. In both obese and nonobese patients, improved RAND-36 physical component summary and mental component summary scores were seen in comparison with the preoperative values. Yet, obese patients had a more pronounced diminution in their physical component summary and mental component summary scores, whereas nonobese patients maintained their physical and mental health status better. Despite an on-going decline in 12 years after the CABG, both patient groups showed improvements in their health status in comparison with preoperative values. Obese patients gained less benefit in terms of QoL dimension, but there was no significant difference in overall mortality in the long-term follow-up.

Self-reported confidence ratings have been used in other research disciplines as a tool to assess data quality, and may be useful in epidemiologic studies. We examined whether self-reported confidence in recall of physical activity was a predictor of the validity and retest reliability of physical activity measures from the European Prospective Investigation into Cancer and Nutrition (EPIC) past-year questionnaire and the International Physical Activity Questionnaire (IPAQ) last-7-day questionnaire.During 2005-2006 in Sydney, Australia, 97 men and 80 women completed both questionnaires at baseline and at 10 months and wore an accelerometer as an objective comparison measure for three 7-day periods during the same timeframe. Participants rated their confidence in recalling physical activity for each question using a 5-point scale and were dichotomized at the median confidence value. Participants in the high-confidence group had higher validity and repeatability coefficients than those in the low-confidence group for most comparisons. The differences were most apparent for validity of IPAQ moderate activity: Spearman correlation rho = 0.34 (95% confidence interval [CI] = 0.08 to 0.55) and 0.01 (-0.17 to 0.20) for high- and low-confidence groups, respectively; and repeatability of EPIC household activity: rho = 0.81 (0.72 to 0.87) and 0.63 (0.48 to 0.74), respectively, and IPAQ vigorous activity: rho = 0.58 (0.43 to 0.70) and 0.29 (0.07 to 0.49), respectively. Women were less likely than men to report high recall confidence of past-year activity (adjusted odds ratio = 0.38; 0.18 to 0.80). Confidence ratings could be useful as indicators of recall accuracy (ie, validity and repeatability) of physical activity measures, and possibly for detecting differential measurement error and identifying questionnaire items that require improvement.

To investigate tissue-dependent cerebral energy metabolism by measuring high energy phosphate levels in unmedicated adolescents diagnosed with bipolar I disorder. Phosphorus-31 magnetic resonance spectroscopic imaging data were acquired over the entire brain of 24 adolescents with bipolar I disorder and 19 demographically matched healthy comparison adolescents. Estimates of phosphocreatine (PCr) and adenosine triphosphate (ATP, determined from the γ-resonance) in homogeneous gray and white matter in the right and left hemispheres of the cerebrum of each subject were obtained by extrapolation of linear regression analyses of metabolite concentrations vs. voxel gray matter fractions. Multivariate analyses of variance showed a significant effect of group on high energy phosphate concentrations in the right cerebrum (p=0.0002) but not in the left (p=0.17). Post-hoc testing in the right cerebrum revealed significantly reduced concentrations of PCr in gray matter and ATP in white matter in both manic (p=0.002 and 0.0001, respectively) and euthymic (p=0.004 and 0.002, respectively) bipolar I disorder subjects relative to healthy comparisons. The small sample sizes yield relatively low statistical power between manic and euthymic groups; cross-sectional observations limit the ability to determine if these findings are truly independent of mood state. Our results suggest bioenergetic impairment - consistent with downregulation of creatine kinase - is an early pathophysiological feature of bipolar I disorder. Copyright © 2015 Elsevier B.V.

To determine the safety and efficacy of vaccination of pregnant gilts with an attenuated strain of porcine reproductive and respiratory syndrome virus (PRRSV). 16 pregnant gilts. Pregnant gilts free of antibodies for PRRSV were assigned (4 gilts/group) to the following groups: group I, untreated controls; group II, vaccinated on day 60 of gestation; group III, vaccinated on day 60 of gestation and exposed to virulent PRRSV on day 90 of gestation; and group IV, exposed to virulent PRRSV on day 90 of gestation. Safety and efficacy of vaccination was evaluated by group comparisons of prenatal and postnatal survival of fetuses and pigs, respectively, and by the condition and rate of weight gain of liveborn pigs. Collective (prenatal and postnatal) death losses up to day 15 after farrowing (conclusion of study) were similar for groups I (7/47, 14.9%) and II (7/44, 16.9%) but were greater for group III (18/49, 36.7%) and were greater still for group IV (23/37, 62.2%). Mean body weight 15 days after farrowing was greatest for pigs in litters of group I (4.46 kg) and progressively less for the other groups (3.87, 3.76, and 2.18 kg for groups II, III, and IV, respectively). Using these conditions, vaccination of gilts during midgestation appeared to be safe. However, it provided only partial protection against subsequent exposure to virulent virus. Attenuated-PRRSV vaccines may have to be administered to naive gilts > 30 days before conception to provide maximum protection throughout gestation.

The Disease Activity Score based on 28 joints (DAS28) has been widely used in clinical practice and research studies of rheumatoid arthritis (RA). The objective of this study was to evaluate the discordance in the DAS28 based on the erythrocyte sedimentation rate (ESR) versus C-reactive protein (CRP) levels in Korean patients with RA. From August to December 2011, 540 patients with RA who visited two rheumatology clinics affiliated with Hallym University (Korea) and had at least one DAS28 evaluation were examined. The mean age of the included patients was 53 years, and 82% were female. The mean duration of disease was 32.9 ± 41.2 months. The mean DAS28-ESR was higher than the DAS28-CRP (3.65 vs. 3.44; P < 0.001). In the DAS28-ESR group, 126 patients (23.3%) satisfied the criteria for remission versus 134 (24.8%) in the DAS28-CRP group. High disease activity was determined in 80 (14.8%) patients in the DAS28-ESR group and in 43 (8.0%) in the DAS28-CRP group. A comparison of the two groups with respect to four DAS28 disease activity categories showed agreement in 344 patients (63.7%; κ = 0.45). In classifying patients as European League Against Rheumatism (EULAR) responders, agreement between the two methods was shown in 56 patients (71.8%; κ = 0.76). When disagreements between the two scores occurred, more patients had a better EULAR response based on the DAS28-ESR than on the DAS28-CRP (19.2% vs. 8.9%, respectively). The discordance between the ESR-based and CRP-based DAS28 could affect clinical treatment decisions for patients with RA. © 2015 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

Cough is a prominent symptom across a range of common chronic respiratory diseases and impacts considerably on patient health status. We undertook a cross-sectional comparison of scores from two cough-specific health-related quality of life (HRQoL) questionnaires, the Leicester Cough Questionnaire (LCQ), and the Cough Quality of Life Questionnaire (CQLQ), together with a generic HRQoL measure, the EuroQol. Questionnaires were administered to and spirometry performed on 147 outpatients with chronic cough (n = 83), COPD (n = 18), asthma (n = 20), and bronchiectasis (n = 26). There was no significant difference in the LCQ and CQLQ total scores between groups (p = 0.24 and p = 0.26, respectively). Exploratory analyses of questionnaire subdomains revealed differences in psychosocial issues and functional impairment between the four groups (p = 0.01 and p = 0.05, respectively). CQLQ scores indicated that chronic coughers have more psychosocial issues than patients with bronchiectasis (p = 0.03) but less functional impairment than COPD patients (p = 0.04). There was a significant difference in generic health status across the four disease groups (p = 0.04), with poorest health status in COPD patients. A significant inverse correlation was observed between CQLQ and LCQ in each disease group (chronic cough r = - 0.56, p < 0.001; COPD r = - 0.49, p = 0.04; asthma r = - 0.94, p < 0.001; and bronchiectasis r = - 0.88, p < 0.001). There was no correlation between cough questionnaire scores and FEV(1) in any group, although a significant correlation between EuroQol visual analog scale component and FEV(1) (r = 0.639, p = 0.004) was observed in COPD patients. Cough adversely affects health status across a range of common respiratory diseases. The LCQ and CQLQ can each provide important additional information concerning the impact of cough.

Low-dose combined oral contraceptives (COCs) can interfere with bone mass acquisition during adolescence. This study aimed to evaluate bone mineral density (BMD) and bone mineral content (BMC) in female adolescents taking a standard low-dose COC (ethinylestradiol 20 μg/desogestrel 150 μg) over a 1-year period and to compare their data with those of healthy adolescents from the same age group not taking COCs. This was a non-randomized parallel-control study with a 1-year follow-up. Sixty-seven adolescents aged from 12 to 19 years, divided into COC users (n = 41) taking 20 μg ethinylestradiol/150 μg desogestrel and COC non-user controls (n = 26), were evaluated by bone densitometry examinations at baseline and after 12 months. Comparisons between the groups at the study onset were performed using the Mann-Whitney test with the significance level fixed at 5% or p < 0.05. Comparisons between the groups at the study onset and after 12 months were based on variations in the median percentages for bone mass variables. The COC users presented with low bone mass acquisition in the lumbar spine, and had BMD and BMC median variations of 2.07% and +1.57%, respectively, between the measurements at baseline and 12 months. The control group had median variations of +12.16% and +16.84% for BMD and BMC, respectively, over the same period. The total body BMD and BMC showed similar evolutions during the study in both groups. Statistical significance (p < 0.05) was seen for the BMC percentage variation between COC users and non-users. Use of a low-dose COC (ethinylestradiol 20 μg/desogestrel 150 μg) was associated with lower bone mass acquisition in adolescents during the study period. Registry Number, RBR-5h9b3c.

Purpose The purpose of this study was to compare the visual outcomes and subjective visual quality between bilateral implantation of a diffractive trifocal intraocular lens, Alcon Acrysof IQ® PanOptix® TNFT00 (group A), and blended implantation of an extended depth of focus lens, J&J Tecnis Symfony® ZXR00 with a diffractive bifocal intraocular lens, J&J Vision Tecnis® ZMB00 (group B). Methods This prospective, nonrandomized, consecutive, comparative study included the assessment of 40 eyes in 20 patients implanted with multifocal intraocular lens. Exclusion criteria were existence of any corneal, retina, or optic nerve disease, previous eye surgery, illiteracy, previous refractive surgery, high axial myopia, expected postoperative corneal astigmatism of >1.00 cylindrical diopter (D), and intraoperative or postoperative complications. Binocular visual acuity was tested in all cases. Ophthalmological evaluation included the measurement of uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near visual acuity (UNVA), and uncorrected intermediate visual acuity (UIVA), with the analysis of contrast sensitivity (CS), and visual defocus curve. Results Postoperative UDVA was 0.01 and −0.096 logMAR (p<0.01) in groups A and B, respectively; postoperative CDVA was −0.07 and −0.16 logMAR (p<0.01) in groups A and B, respectively; UIVA was 0.14 and 0.20 logMAR (p<0.01) in groups A and B, respectively; UNVA was −0.03 and 0.11 logMAR (p<0.01) in groups A and B, respectively. Under photopic conditions group B had better CS at low frequencies with and without glare. Conclusion Both groups promoted good quality of vision for long, intermediate, and short distances. Group B exhibited a better performance for very short distances and for intermediate and long distances ≥−1.50 D of vergence. Group A exhibited a better performance for UIVA at 60 cm and for UNVA at 40 cm. PMID:29138533

There were limited data available for a head-to-head comparison of the identification rate and survival between the combined method of indocyanine green fluorescence and blue dye versus the traditional blue dye alone method for sentinel lymph node (SLN) biopsy. From January 2013 to December 2015, 523 eligible breast cancer patients were included in this nonrandomized prospective analysis. The identification rates, the number of SLNs identified, and the disease-free survival (DFS) between the two mapping methods were compared. The identification rate of SLNs was significantly higher with the combined method than that with the blue dye alone method (99.2% vs 93.3%, respectively; P < 0.001). The average number of SLNs identified per patient in the combined method group was 3.7 ± 2.4, which was more than that in the blue dye alone group (3.2 ± 1.6; P = 0.004). With a median follow-up of 29 months, 0.5% patients in the combined group, and 1.3% patients in the blue dye group had axillary recurrences. The DFS between the two groups showed no significant difference (P = 0.161). The combined method achieved a higher identification rate and lower rate of axillary recurrence compared to the blue dye alone method. © 2018 Wiley Periodicals, Inc.

Objective: A retrospective comparison between Nissen and Dor fundoplication after laparoscopic Heller myotomy for achalasia. Materials and Methods: From 1998 to 2004 a first group of 48 patients underwent Heller myotomy and Nissen fundoplication for idiopathic achalasia (H+N group). From 2004 to 2010 a second group of 40 patients underwent Heller myotomy followed by Dor fundoplication (H+D group). Some patients received a previous endoscopic treatment with pneumatic dilatation or endoscopic injection of botulinum toxin that provided them only a temporary clinical benefit. Changes in clinical and instrumental examinations from before to after surgery were evaluated in all patients. Clinical evaluation was carried out using a modified DeMeester symptom score system. Results: Dor fundoplication treatment reduced both dysphagia and regurgitation severity scores significantly more than Nissen fundoplication (p<0.0001). Indeed, the incidence of dysphagia was significantly higher in patients treated with floppy-Nissen than in those treated with Dor fundoplication: by defining dysphagia as a DeMeester score equal to 3 (arbitrary cut-off), at the end of follow-up dysphagia occurred in 17.65% and 0% (p=0.037) of patients belonging to the H+N and H+D groups, respectively. Conclusion: Heller myotomy followed by Dor fundoplication is a safe and valuable treatment. The procedure showed a lower incidence of postoperative dysphagia versus Nissen fundoplication and a negligible incidence of postoperative GERD in a long-term postoperative follow-up. PMID:25610181

To investigate the effect of a school-based intervention called Travelling Green (TG) on children's walking to and from school and total daily physical activity. A quasi-experiment with 166 Scottish children (8-9 years) was conducted in 2009. One group (n=79) received TG and another group (n=87) acted as a comparison. The intervention lasted 6 weeks and consisted of educational lessons and goal-setting tasks. Steps and MVPA (daily, a.m. commute, p.m. commute, and total commute) were measured for 5 days pre- and post-intervention using accelerometers. Mean steps (daily, a.m., p.m., and total commute) decreased from pre- to post-intervention in both groups (TG by 901, 49, 222, and 271 steps/day and comparison by 2528, 205, 120, and 325 steps/day, respectively). No significant group by time interactions were found for a.m., p.m., and total commuting steps. A medium (partial eta squared=0.09) and significant (p<0.05) group by time interaction was found for total daily steps. MVPA results were similar to step results. TG has a little effect on walking to and from school. However, for total daily steps and daily MVPA, TG results in a smaller seasonal decrease than for children who do not receive the intervention.

High-intensity interval training (HIIT) may be a feasible and efficacious strategy for improving health-related fitness in young people. The objective of this systematic review and meta-analysis was to evaluate the utility of HIIT to improve health-related fitness in adolescents and to identify potential moderators of training effects. Studies were considered eligible if they: (1) examined adolescents (13-18 years); (2) examined health-related fitness outcomes; (3) involved an intervention of ≥4 weeks in duration; (4) included a control or moderate intensity comparison group; and (5) prescribed high-intensity activity for the HIIT condition. Meta-analyses were conducted to determine the effect of HIIT on health-related fitness components using Comprehensive Meta-analysis software and potential moderators were explored (ie, study duration, risk of bias and type of comparison group). The effects of HIIT on cardiorespiratory fitness and body composition were large, and medium, respectively. Study duration was a moderator for the effect of HIIT on body fat percentage. Intervention effects for waist circumference and muscular fitness were not statistically significant. HIIT is a feasible and time-efficient approach for improving cardiorespiratory fitness and body composition in adolescent populations. Published by the BMJ Publishing Group Limited.

Objective: We report our experience with hand-assisted laparoscopic nephroureterectomy (HALN) for upper urinary tract transitional cell carcinoma and compare our results with a contemporary series of open nephroureterectomy (ON) performed at our institution. Methods: Between August 1996 and May 2003, 90 patients underwent nephroureterectomy for upper-tract transitional cell carcinoma (TCC). Thirty-eight patients underwent HALN, while 52 had an ON. End-points of comparison included operative time, estimated blood loss (EBL), intraoperative and postoperative complications, length of hospital stay, pathologic grade and stage of tumor, and tumor recurrence. Results: The mean patient age was 72.3 and 70.6 years in the ON and HALN groups, respectively. Mean operative duration was 243 minutes (ON) and 244 minutes (HALN), with an EBL of 478mL in the open group versus 191mL in the hand-assisted group (P<0.001). No intraoperative complications occurred, but postoperative complications occurred in 4% and 11% of the ON and HALN groups, respectively (P=0.21). The mean hospital duration was 7.1 days (ON) versus 4.6 days (HALN) (P<0.01). No difference existed in the pathologic grade or stage distribution of urothelial tumors between the 2 groups. The mean follow-up was 51.0 months in the ON group and 31.7 months in the HALN group. Recurrence of urothelial carcinoma occurred in 50% of patients who underwent ON and 40% treated by HALN (P=0.38) at a median interval of 9.1 and 7.7 months, respectively, after surgery. Conclusion: Hand-assisted laparoscopic nephroureterectomy is an effective modality for the treatment of upper urinary tract urothelial carcinoma. Patients benefited from less intraoperative blood loss and a shorter hospitalization with an equivalent intermediate-term oncologic outcome compared with that of the open approach. PMID:17575752

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

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.

Abstract Pericardial effusion is an important late toxicity after concurrent chemoradiotherapy (CCRT) for locally advanced esophageal cancer. We investigated the clinical and dosimetric factors that were related to pericardial effusion among patients with thoracic esophageal cancer who were treated with definitive CCRT using the two opposed fields technique (TFT) or the four-field technique (FFT), as well as the effectiveness of FFT. During 2007–2015, 169 patients with middle and/or lower thoracic esophageal cancer received definitive CCRT, and 94 patients were evaluable (51 FFT cases and 43 TFT cases). Pericardial effusion was observed in 74 patients (79%) and appeared at 1–18.5 months (median: 5.25 months) after CCRT. The 1-year incidences of pericardial effusions were 73.2% and 76.7% in the FFT and TFT groups, respectively (P = 0.6395). The mean doses to the pericardium were 28.6 Gy and 31.8 Gy in the FFT and TFT groups, respectively (P = 0.0259), and the V40 Gy proportions were 33.5% and 48.2% in the FFT and TFT groups, respectively (P < 0.0001). Grade 3 pericardial effusion was not observed in patients with a pericardial V40 Gy of <40%, or in patients who were treated using the FFT. Although the mean pericardial dose and V40 Gy in the FFT group were smaller than those in the TFT group, the incidences of pericardial effusion after CCRT were similar in both groups. As symptomatic pericardial effusion was not observed in patients with a pericardial V40 Gy of <40% or in the FFT group, it appears that FFT with a V40 Gy of <40% could help minimize symptomatic pericardial effusion.

The aim of this study was to evaluate the effect of an electromagnetic field (EMF), generated close to the ovaries, on primordial follicles. A total of 16 rats were used in this study. The study group consisted of rats exposed to an EMF in the abdominal region for 15 min/d for 15 days. Both the study and control group were composed of eight rats. After the treatment period of 15 days, the ovaries of the rats were extracted, and sections of ovarian tissue were taken for histological evaluation. The independent samples t test was used to compare the two groups. In the study group, the means of the right and left ovarian follicle numbers were 34.00 ± 10.20 and 36.00 ± 10.53, respectively. The average total ovarian follicle number was 70.00 ± 19.03. In the control group, the means of the right and left ovarian follicle numbers were 78.50 ± 25.98 and 71.75 ± 29.66, respectively, and the average total ovarian follicle number was 150.25 ± 49.53. The comparisons of the means of the right and left ovarian follicle numbers and the means of the total ovarian follicle numbers between the study and control groups indicated that the study group had significantly fewer follicles (p < 0.001, p = 0.011, and p = 0.002, respectively). This study found a significant decrease in the number of ovarian follicles in rats exposed to an EMF. Further clinical studies are needed to reveal the effects of EMFs on ovarian reserve and infertility. Copyright © 2015. Published by Elsevier Taiwan.

Sarcopenia is known to be associated with poor clinical outcome in patients with diffuse large B-cell lymphoma (DLBCL). There is no consensus concerning the optimal method to define sarcopenia in DLBCL. We retrospectively reviewed 193 DLBCL patients treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) therapy. Sarcopenia was classified by the region where the pretreatment skeletal muscle index (SMI) was measured. Both the sarcopenia-L3 and sarcopenia-pectoralis muscle (PM) groups had increased incidences of severe treatment-related toxicities and treatment discontinuation compared with the non-sarcopenia-L3 and non-sarcopenia-PM groups, respectively. The sarcopenia-L3 and non-sarcopenia-L3 groups had 5-year overall survival (OS) rates of 40.5% and 67.8% (p < 0.001), respectively. The sarcopenia-PM and non-sarcopenia-PM groups had 5-year OS rates of 35.9% and 69.0% (p < 0.001), respectively. When the sarcopenia-L3 alone and sarcopenia-PM alone groups were compared, there were no differences in baseline characteristics, treatment toxicity, or survival. In multivariate analysis, when compared with the non-sarcopenia-both group, OS was significantly worse in the sarcopenia-both group (HR, 2.480; 95% CI, 1.284 - 4.792; p = 0.007), but not in patients with either sarcopenia-L3 alone or sarcopenia-PM alone (p = 0.151). L3- and PM-SMIs are equally useful to define sarcopenia, which is related to intolerance to R-CHOP therapy and to worse survival in patients with DLBCL. More prognostic information can be obtained when these two SMIs are combined to define sarcopenia.

The present study investigated the genetic diversities of 30 autosomal insertion and deletion (InDel) loci of Investigator DIPplex kit (Qiagen) in Chinese Salar ethnic minority and explored the genetic relationships between the studied Salar group and other populations. The allelic frequencies of deletion alleles at the 30 InDel loci were in the range of 0.1739 (HLD64) to 0.8478 (HLD39). The discrimination power, polymorphism information content and probability of exclusion ranged from 0.4101 (HLD39) to 0.6447 (HLD136), 0.2247 (HLD39) to 0.3750 (HLD92) and 0.0400 (HLD39) to 0.2806 (HLD92), respectively. The observed and expected heterozygosity were in the range of 0.2348 (HLD39) to 0.5913 (HLD92), and 0.2580 (HLD39) to 0.5000 (HLD92), respectively. The cumulative discrimination power and probability of exclusion of the 30 loci reached 0.999999999993418 and 0.99039, respectively. The results of population genetic differentiation comparisons revealed that Salar group had similar allele distributions with Qinghai Tibetan, Xibe and Yi groups. Population Bayesian cluster analysis showed that there were similar ancestry components between Salar group and most Chinese populations. Besides, the principal components analysis and phylogenetic reconstructions further indicated that Salar group had intimate genetic relationships with Qinghai Tibetan and Xibe groups. In short, the results of the current studies indicated the genetic distributions of the 30 InDel loci in Salar group were relatively high genetic polymorphisms, which could be used in forensic individual identifications and as a supplementary tool for complex paternity testing.

Objectives Comparison groups are essential for accurate testing and interpretation of yoga intervention trials. However, selecting proper comparison groups is difficult because yoga comprises a very heterogeneous set of practices and its mechanisms of effect have not been conclusively established. Methods We conducted a systematic review of the control and comparison groups used in published randomized controlled trials (RCTs) of yoga. Results We located 128 RCTs that met our inclusion criteria; of these, 65 included only a passive control and 63 included at least one active comparison group. Primary comparison groups were physical exercise (43%), relaxation/meditation (20%), and education (16%). Studies rarely provided a strong rationale for choice of comparison. Considering year of publication, the use of active controls in yoga research appears to be slowly increasing over time. Conclusions Given that yoga has been established as a potentially powerful intervention, future research should use active control groups. Further, care is needed to select comparison conditions that help to isolate the specific mechanisms of yoga’s effects. PMID:25440384

Several pacing modalities across multiple manufacturers have been introduced to minimize unnecessary right ventricular pacing. We conducted a meta-analysis to assess whether ventricular pacing reduction modalities (VPRM) influence hard clinical outcomes in comparison to standard dual-chamber pacing (DDD). An electronic search was performed using Cochrane Central Register, PubMed, Embase, and Scopus. Only randomized controlled trials (RCT) were included in this analysis. Outcomes of interest included: frequency of ventricular pacing (VP), incident persistent/permanent atrial fibrillation (PerAF), all-cause hospitalization and all-cause mortality. Odds ratios (OR) were reported for dichotomous variables. Seven RCTs involving 4119 adult patients were identified. Ventricular pacing reduction modalities were employed in 2069 patients: (MVP, Medtronic Inc.) in 1423 and (SafeR, Sorin CRM, Clamart) in 646 patients. Baseline demographics and clinical characteristics were similar between VPRM and DDD groups. The mean follow-up period was 2.5 ± 0.9 years. Ventricular pacing reduction modalities showed uniform reduction in VP in comparison to DDD groups among all individual studies. The incidence of PerAF was similar between both groups {8 vs. 10%, OR 0.84 [95% confidence interval (CI) 0.57; 1.24], P = 0.38}. Ventricular pacing reduction modalities showed no significant differences in comparison to DDD for all-cause hospitalization or all-cause mortality [9 vs. 11%, OR 0.82 (95% CI 0.65; 1.03), P= 0.09; 6 vs. 6%, OR 0.97 (95% CI 0.74; 1.28), P = 0.84, respectively]. Novel VPRM measures effectively reduce VP in comparison to standard DDD. When actively programmed, VPRM did not improve clinical outcomes and were not superior to standard DDD programming in reducing incidence of PerAF, all-cause hospitalization, or all-cause mortality.

Studies that have investigated the epidemiological relationship between thalassaemia and cancers are scarce. Therefore, we conducted a longitudinal nationwide cohort study to determine whether patients with thalassaemia are at an increased risk of cancer. We investigated the incidence and risk of cancer in 2655 patients diagnosed with thalassaemia between 1998 and 2010 by using data from the Taiwan Longitudinal Health Insurance Database. The comparison cohort comprised 10 620 people from the general population without thalassaemia. The follow-up period extended from the diagnostic date for thalassaemia to the date of a cancer diagnosis, censoring or 31 December 2011. We used Cox proportional hazard regression models to analyse the risks of cancer. The incidences of cancer were 3.96 and 2.60/1000 person-years for the thalassaemia and comparison cohorts, respectively. The overall incidence of cancer was 52% higher in the thalassaemia cohort than in the comparison cohort, with an adjusted HR (aHR) of 1.54 (95% CI 1.15 to 2.07). Patients with thalassaemia had a considerably higher risk of haematological malignancy (aHR=5.32, 95% CI 2.18 to 13.0) and abdominal cancer (aHR=1.96, 95% CI 1.22 to 3.15) than did the comparison cohort. Furthermore, patients with thalassaemia with transfusion exhibited a 9.31-fold risk for developing haematological malignancy and a 9.12-fold risk for developing abdominal cancer compared with those who did not receive transfusion. This nationwide retrospective cohort study indicates that patients with thalassaemia carried substantial risks of haematological malignancy and abdominal cancer compared with those of the general population.

The aim was to compare periodontal and periimplant inflammatory parameters (plaque index [PI], bleeding on probing [BOP], probing depth [PD] and marginal bone loss [MBL]) among patients with prediabetes, type-2 diabetes mellitus (T2DM) and non-diabetic controls. Forty-five patients with prediabetes (Group-1), 43 patients with T2DM (Group-2) and 42 controls (Group-3) were included. Demographic data was recorded using a questionnaire. Full mouth and periimplant clinical (PI, BOP and PD) were assessed and the radiographic MBL were measured on digital radiographs. In all groups, haemoglobin A1c (HbA1c) levels were also measured. p values less than .05 were considered statistically significant. The mean HbA1c levels of participants in groups 1, 2 and 3 were 6.1%, 8.4% and 4.8%, respectively. The mean duration of prediabetes and T2DM among patients in groups 1 and 2 were 1.9 ± 0.3 and 3.1 ± 0.5 years, respectively. Periodontal and periimplant PI, BOP, PD and MBL were higher in groups 1 (p < .05) and 2 (p < .05) than group 3. There was no difference in these parameters in groups 1 and 2. Periodontal and periimplant inflammatory parameters were worse among patients with prediabetes and T2DM compared with controls; however, these parameters were comparable among patients with prediabetes and T2DM.

To evaluate the oncological outcomes and complications of patients with saturated prostate cryoablation. A cohort of 208 patients cumulatively treated between June 2008 and December 2012 qualified for study inclusion, each undergoing total-gland cryoablation for prostate cancer. The degree of saturated prostate cryoablation was defined as the average prostate volume per cryoprobe (APVC), and divided into four groups (groups 1-4: <3 ml, 3 to <4 ml, 4 to <5 ml, ≧5 ml, respectively). Post-ablative complications were measured prospectively at weeks 1, 2, 4, 8, 12, and 24 by using the Common Terminology Criteria for Adverse Events. Biochemical failure was gauged by Phoenix criterion. The Kruskal-Wallis rank sum test and Chi-square test were used to compare clinical characteristics of therapeutic subsets. The Cox proportional hazard model was applied for comparison of recurrence risk between groups. APVC group 1 had the highest pre-operative PSA value and smallest prostate size among the groups. Multivariate analysis of risks of biochemical failures revealed that the larger the APVC, the higher the hazard (p for trend = 0.01). Compared to the group 1 patients, the hazard ratios of biochemical failures in groups 2-4 were 4.4 (confidence interval (CI): 0.5-37), 8.8 (CI 1.1-73), and 9.4 (CI 1.1-78), respectively. Nevertheless, the complication rate of APVC group 1 patients was similar to the other three groups. Saturated prostate cryoablation by reducing APVC would be beneficial for cancer control without compromising patient safety.

Novel methods for teaching are needed to enhance the efficiency of academic anesthesia departments as well as provide approaches to learning that are aligned with current trends and advances in technology. A video was produced that taught the key elements of anesthesia machine checkout and room set up. Novice learners were randomly assigned to receive either the new video format or traditional lecture-based format for this topic during their regularly scheduled lecture series. Primary outcome was the difference in written examination score before and after teaching between the two groups. Secondary outcome was the satisfaction score of the trainees in the two groups. Forty-two students assigned to the video group and 36 students assigned to the lecture group completed the study. Students in each group similar interest in anesthesia, pre-test scores, post-test scores, and final exam scores. The median posttest to pretest difference was greater in the video groups (3.5 (3.0-5.0) vs 2.5 (2.0-3.0), for video and lecture groups respectively, p 0.002). Despite improved test scores, students reported higher satisfaction the traditional, lecture-based format (22.0 (18.0-24.0) vs 24.0 (20.0-28.0), for video and lecture groups respectively, p <0.004). Higher pre-test to post-test improvements were observed among students in the video-based teaching group, however students rated traditional, live lectures higher than newer video-based teaching.

To compare the effectiveness and safety of pneumatic and holmium:YAG laser lithotripters in the treatment of pediatric ureterolithiasis. Medical records of patients treated using pneumatic (PL) (n = 29) or laser (LL) (n = 35) lithotripter between 2009 and 2011 were retrospectively analysed. The patients were evaluated with respect to age, gender, stone size, complications, and stone-free rates 1 month after the operation. For the PL and LL groups, mean ages (8.8 ± 3.4 and 8.3 ± 3.5 years), male/female ratios (19:10 and 22:13) and stone locations were similar (p > 0.05). Mean stone sizes were 55.6 mm2 and 47.6 mm2 in the PL and LL group, respectively, with no statistically significant difference (p = 0.850). Mean operative times were 20.5 min in the PL group and 25.2 min in the LL group, with a statistically significant difference (p = 0.020). Stone-free rates 1 month after intervention were 79% in the PL group and 97% in the LL group (p = 0.022). Stone migration was detected in the PL group (n = 6) and in the LL group (n = 1). No major complication was found in either group. In the ureteroscopic treatment of pediatric ureterolithiasis, both pneumatic and laser lithotripters are effective and successful. However, laser lithotripsy has a higher stone-free rate and lower complication rate. Copyright © 2012 Journal of Pediatric Urology Company. Published by Elsevier Ltd. All rights reserved.

ABSTRACT Objective: Compare immune persistence from one dose of each of 3 different hepatitis A vaccines when given to school-age children: a domestic, live attenuated hepatitis A vaccine (H2 vaccine); a domestic inactivated hepatitis A vaccine (Healive®); and an imported, inactivated hepatitis A vaccine (Havrix®),.Methods: School-age children were randomized into 1 of 4 groups to receive a single dose of a vaccine: H2 vaccine, Healive®, Havrix®, or hepatitis B vaccine [control]. Serum samples were collected 12 and 24 months after vaccination for measurement of anti-HAV IgG using microparticle enzyme immunoassay. Seropositivity was defined as ≥ 20 mUI/ml. We compared groups on seropositivity and geometric mean concentration (GMC). Results: Seropositive rates for the H2, Healive®, Havrix®, and control groups were 64%, 94.4%, 73%, and 1.0%, respectively, 12-months post-vaccination; and 63%, 95.6%, 72%, and 1.0%, respectively 24-months post-vaccination. Seropositivity was greater for Healive® than for H2 and Havrix® at 12 months (p-values < 0.001) and 24 months (p-values < 0.0001). Average GMCs for the H2, Healive®, Havrix®, and control groups, in mIU/ml, were 29.7, 81.0, 36.4, and 2.9, respectively at 12 months, and 30.9, 112.2, 44.3, and 2.9, respectively, at 24 months. GMCs were greater for Healive® than for H2 and Havrix® at 12 months (p-values < 0.0001 and < 0.001, respectively) and 24 months (p-values < 0.001). No statistically significant differences in seropositivity or GMC were found within groups between 12 and 24 months. Conclusion: Immunity persisted 24 months after a single dose of inactivated hepatitis A vaccine and live attenuated hepatitis A vaccine. PMID:27494260

The goal of the study was to evaluate the effect of caries removal by three various methods on the permeability of class II composite resin restorations in primary molar teeth. Forty-five recently extracted primary molars were randomly assigned to three groups for three different methods of caries removal; group 1-mechanical, group 2-caries detector dye, and group 3-Carisolv (n = 15). After that, class II cavities in all groups were restored with the adhesive (Opti Bond Solo Plus) that was applied according to the manufacturer's instruction and a posterior composite (Herculite XRV), which was used incrementally. After 24 hours the samples were thermocycled in water for 500 cycles between 5 and 55°C with a dwell time of 30 sec. Permeability was assessed by the fluid filtration method. The data were analyzed using the ANOVA test while study groups were compared with Tukey test for statistically significant differences at a 5% significance level. The evaluation of tested groups indicated that the highest (0.80) and least (0.37) mean of permeability was observed in group 2 and 3 respectively. Significant difference was revealed among the tested groups (p = 0.045). The comparison of Carisolv and caries detector dye groups indicated a statistically significant difference (p = 0.037). There was not any significant difference between Carisolv or caries dye in the conventional group. Using the chemomechanical and staining methods for caries removal had no more detrimental effect on permeability than the conventional technique. However, caries detection dye for caries removal could be more harmful than chemomechanical method. None of the current caries-excavation techniques could eliminate permeability in class II composite resin restorations. Furthermore, staining methods do not have an adverse effect on sealing ability in comparison to the conventional technique.

Independent component analysis (ICA) has been widely used to study functional magnetic resonance imaging (fMRI) connectivity. However, the application of ICA in multi-group designs is not straightforward. We have recently developed a new method named “shared and specific independent component analysis” (SSICA) to perform between-group comparisons in the ICA framework. SSICA is sensitive to extract those components which represent a significant difference in functional connectivity between groups or conditions, i.e., components that could be considered “specific” for a group or condition. Here, we investigated the performance of SSICA on realistic simulations, and task fMRI data and compared the results with one of the state-of-the-art group ICA approaches to infer between-group differences. We examined SSICA robustness with respect to the number of allowable extracted specific components and between-group orthogonality assumptions. Furthermore, we proposed a modified formulation of the back-reconstruction method to generate group-level t-statistics maps based on SSICA results. We also evaluated the consistency and specificity of the extracted specific components by SSICA. The results on realistic simulated and real fMRI data showed that SSICA outperforms the regular group ICA approach in terms of reconstruction and classification performance. We demonstrated that SSICA is a powerful data-driven approach to detect patterns of differences in functional connectivity across groups/conditions, particularly in model-free designs such as resting-state fMRI. Our findings in task fMRI show that SSICA confirms results of the general linear model (GLM) analysis and when combined with clustering analysis, it complements GLM findings by providing additional information regarding the reliability and specificity of networks.

To evaluate results of margin convergence versus suture anchors in rotator cuff repair, and to determine which method is mechanically superior. Eighteen kangaroo shoulders were randomly divided into three groups (n = 6). A full thickness tendon defect 1.0 cm × 1.5 cm in size was created in the supraspinatus tendon at humeral insertion, simulating a massive rotator cuff tear. Three different techniques were employed for rotator cuff repair: (i) Mitek GII suture anchor alone (Group 1); (ii) margin convergence alone (Group 2); and (iii) margin convergence plus Mitek GII suture anchor (Group 3). Combined loads were applied to each specimen. After completion of cyclic loading, the construct was loaded to failure. ANOVA and LSD (Least Significant Difference) multiple comparisons of the means were applied to results. Cyclic load testing showed progressive gap formation in each repaired specimen with increasing cycles. Group 1 reached 50% failure at an average of 34 cycles, Group 2 at 75 cycles and Group 3 at 73 cycles. There were significant difference between Groups 1 and 2, and Groups 1 and 3 (P ≤ 0.001). After 100 loading cycles, the average gap size was 6.8 mm, 6.1 mm and 4.7 mm in Groups 1, 2 and 3, respectively. There was a significant difference between Groups 1 and 3 (P ≤ 0.015). All specimens eventually reached failure. Rotator cuff repairs with margin convergence +/- suture anchor were far stronger than suture anchor alone, both in gap formation and ultimate failure load. However, progressive gap formation with cyclic loading seems inevitable after cuff repair, which may facilitate clinical understanding of the phenomena of re-tear or residual defect. © 2009 Tianjin Hospital and Blackwell Publishing Asia Pty Ltd.

The purpose of the study was to evaluate the fracture strength of provisional fixed partial dentures made of autopolymerizing polymethylmethacrylate (PMMA) resin using different types of reinforcement materials to determine the best among them. Fifty samples were made (10 samples for each group) with autopolymerizing PMMA resin using reinforcement materials (stainless steel wire: looped and unlooped and glass fiber: loose and unidirectional) as 3-unit posterior bridge. The test specimens were divided into five groups depending on the reinforcing material as Group I, II, III, IV, and V; Group I: PMMA unreinforced (control group), Group II: PMMA reinforced with stainless steel wire (straight ends), Group III: PMMA reinforced with stainless steel wire (looped ends), Group IV: PMMA reinforced with unidirectional glass fibers, and Group V: PMMA reinforced with randomly distributed glass fibers. Universal testing machine was used to evaluate and compare the fracture strength of samples. Comparison of mean ultimate force and ultimate stress was done employing one-way analysis of variance and Tukey's post hoc tests. The highest and lowest mean ultimate force and mean ultimate stress were of Group IV and I, respectively. Tukey's post hoc honestly significant difference multiple comparison for mean ultimate force and stress shows the increase in strength to be statistically significant ( P < 0.05) except for the samples reinforced with randomly distributed glass fibers ( P > 0.05). Unidirectional glass fibers showed the maximum strength, which was comparable to mean values of both stainless steel wire groups. Low cost and easy technique of using stainless steel wire make it the material of choice over the unidirectional glass fiber for reinforcement in nonesthetic areas where high strength is required.

Sedentary lifestyle combined with smoking, contributes to the development of a set of chronic diseases and to accelerating the course of aging. The aim of the study was to compare the hemodynamic and nutritional parameters between elderly persons practicing regular physical activity, nonsmokers and ex-smokers. The sample was comprised of 40 elderly people practicing regular physical activity for 12 months, divided into a Nonsmoker Group and an Ex-smoker Group. During a year four trimestrial evaluations were performed, in which the hemodynamic (blood pressure, heart rate- HR and VO2) and nutritional status (measured by body mass index) data were collected. The paired t-test and t-test for independent samples were applied in the intragroup and intergroup analysis, respectively. The mean age of the groups was 68.35 years, with the majority of individuals in the Nonsmoker Group being women (n = 15) and the Ex-smoker Group composed of men (n = 11). In both groups the variables studied were within the limits of normality for the age. HR was diminished in the Nonsmoker Group in comparison with the Ex-smoker Group (p = 0.045) between the first and last evaluation. In the intragroup analysis it was verified that after one year of exercise, there was significant reduction in the HR in the Nonsmoker Group (p = 0.002) and a significant increase in VO2 for the Ex-smoker Group (p = 0.010). There are no significant differences between the hemodynamic and nutritional conditions in both groups. In elderly persons practicing regular physical activity, it was observed that the studied variables were maintained over the course of a year, and there was no association with the history of smoking, except for HR and VO2.

Background There have not yet been any published studies on the effects of laughter therapy on radiation-induced dermatitis in breast cancer patients treated with radiotherapy (RT). We assessed the effectiveness of laughter therapy in preventing radiation dermatitis in patients with breast cancer. Methods Thirty-seven patients were prospectively enrolled in this study. Eighteen patients were assigned to the experimental group and the other 19 patients were assigned to the control group. The patients who were assigned to the experimental group received laughter therapy during RT. Laughter therapy was started at the onset of RT and was provided twice a week until completion of RT. The patients who were assigned to the control group only received RT without laughter therapy. The grade of radiation dermatitis was scored by a radiation oncologist who was blinded to subject assignment. The patients’ evaluation of pain within the RT field was also assessed. Results In the experimental group, radiation dermatitis of grade 3, 2, and 1 developed in five (33.3%), five (33.3%), and five patients (33.3%), respectively. In comparison, in the control group, radiation dermatitis of grade 3, 2, 1, and 0 developed in seven (36.8%), nine (47.4%), two (10.5%), and one patient (5.3%), respectively. The experimental group exhibited a lower incidence of grade 2 or worse radiation dermatitis than the control group (33.3% versus 47.4%). The mean maximal pain scores in the experimental and control group were 2.53 and 3.95, respectively. The experimental group complained of less severe pain than the control group during RT. However, these differences were not statistically significant. Conclusion The results of this study show that laughter therapy can have a beneficial role in preventing radiation dermatitis in patients with breast cancer. To confirm the results of our study, well-designed randomized studies with large sample sizes are required. PMID:25395864

To investigate the effects of mild-to-severe retinopathy of prematurity (ROP) on refractive state and the incidence of strabismus. Infants born ≤32 weeks of gestation were prospectively evaluated. Inclusion criteria were a follow-up of at least 6 months and at least stage 1 ROP. Group 1 included stage 1 ROP cases. Cases with stage 2 or 3 ROP without indication for treatment formed the second group. Group 3 included cases who received treatment for ROP. Logistic regression, adjusted for birth weight and gestational age, and multiple comparison tests were used to compare outcomes among groups. The mean follow-up time was 20.9 ± 6.6 months. In the first (n = 21), second (n = 22), and third groups (n = 23), the right spherical equivalents (SE) were 1.17 ± 1.33, -0.18 ± 3.09, and -1.08 ± 4.05 diopters, and the left SEs were 1.23 ± 1.34, -0.09 ± 3.24, and -1.46 ± 4.02 diopters, respectively (p = 0.026 for right SE and 0.008 for left SE). The incidences of anisometropia were 3/21, 4/22, and 11/23 in the first, second, and third groups, respectively (adjusted odds ratios [aOR] for group 3 vs 1 = 5.39, aOR for group 3 vs 2 = 4.06). Strabismus developed in 7/21, 6/22, and 10/23 in groups one, two, and three, respectively (aOR for group 3 vs 1 = 2.06, aOR for group 3 vs 2 = 2.27). Eighteen of these were esotropias. Refractive errors and strabismus were associated with mild-to-severe ROP. Esotropia was the most frequent type of strabismus.

To report the independent prognostic impact of the new prostate cancer grade-grouping system in a large external validation cohort of patients treated with radical prostatectomy (RP). Between 1994 and 2013, 3 694 consecutive men were treated with RP at a single institution. To investigate the performance of and validate the grade-grouping system, biochemical recurrence-free survival (bRFS) rates were assessed using Kaplan-Meier tests, Cox-regression modelling, and discriminatory comparison analyses. Separate analyses were performed based on biopsy and RP grade. The median follow-up was 52.7 months. The 5-year actuarial bRFS for biopsy grade groups 1-5 were 94.2%, 89.2%, 73.1%, 63.1%, and 54.7%, respectively (P < 0.001). Similarly, the 5-year actuarial bRFS based on RP grade groups was 96.1%, 93.0%, 74.0%, 64.4%, and 49.9% for grade groups 1-5, respectively (P < 0.001). The adjusted hazard ratios for bRFS relative to biopsy grade group 1 were 1.98, 4.20, 5.57, and 9.32 for groups 2, 3, 4, and 5, respectively (P < 0.001), and for RP grade groups were 2.09, 5.27, 5.86, and 10.42 (P < 0.001). The five-grade-group system had a higher prognostic discrimination compared with the commonly used three-tier system (Gleason score 6 vs 7 vs 8-10). In an independent surgical cohort, we have validated the prognostic benefit of the new prostate cancer grade-grouping system for bRFS, and shown that the benefit is maintained after adjusting for important clinicopathological variables. The greater predictive accuracy of the new system will improve risk stratification in the clinical setting and aid in patient counselling. © 2016 The Authors BJU International © 2016 BJU International Published by John Wiley & Sons Ltd.
