Correlation between Postoperative Weight Loss and Diabetes Mellitus Remission: A Meta-Analysis

Objective

This meta-analysis was conducted to determine the effect of percent excess weight loss (%EWL) after bariatric surgery on diabetes remission.

Methods

The Cochrane Library, PubMed, MEDLINE, Embase, and CINAHL were searched. All reports on %EWL involving humans and published in English between 1 January 1992 and 1 September 2013 were included in the analysis.

Results

Eight studies involving 1,247 patients who underwent bariatric surgery were selected. %EWL was positively associated with remission rate (WMD?=?11.15, 95 % CI: 6.73–15.56, p?Conclusions Patients with extensive weight loss were more likely to achieve T2DM remission after bariatric surgery. Further randomized controlled trials (RCTs) with uniform remission criterion should be performed to provide more reliable evidence.     

中西方不同的家庭文化观与家庭心理治疗的应用

目的:通过比较国内外不同的家庭文化观,探讨家庭心理治疗在国内应用的特色及其应该注意的问题。方法:通过文献的检索以及作者的临床经验,从不同角度分析家庭心理治疗在中国文化背景下的应用。结果:中国和西方的家庭文化观在3个方面有大的差异:个人与家庭的关系,国内是家庭取向,西方是个人取向;亲子关系,国内注重家长的权威,西方强调人人平等;家庭的性别观,国内认为男人比女人值得尊重,西方认为男女平等。家庭心理治疗在国内的应用,要注意权威,家长制,男人为本等问题的处理。结论:家庭心理治疗是以家庭为治疗对象的心理治疗方法,是传统个体心理治疗的重要补充。家庭心理治疗涉及到诸如文化、历史等范畴,国内学者在应用其方法时不要盲目照搬西方的理论,要结合中国文化背景,发展中国特色的家庭心理治疗。     

Movement disorders in women: A review

The field of women's health developed based on the recognition that there are important sex‐based differences regarding several aspects of medical illnesses. We performed a literature review to obtain information about differences between women and men for neurological movement disorders. We identified important differences in prevalence, genetics, clinical expression, course, and treatment responses. In addition, we found that female life events, including menstruation, pregnancy, breast feeding, menopause, and medications prescribed to women (such as oral contraceptives and hormone‐replacement therapy), have significant implications for women with movement disorders. Understanding this biological sex‐specific information can help improve the quality and individualization of care for women with movement disorders and may provide insights into neurobiological mechanisms. © 2013 International Parkinson and Movement Disorder Society     

Evidence that the LRRK2 ROC domain Parkinson's disease‐associated mutants A1442P and R1441C exhibit increased intracellular degradation

Mutations in the leucine‐rich repeat kinase 2 (lrrk2) gene are the leading genetic cause of Parkinson's disease (PD). In characterizing the novel ROC domain mutant A1442P, we compared its steady‐state protein levels, propensity to aggregate, and toxicity with the pathogenic R1441C mutant and wild‐type (WT) LRRK2. Mutant (R1441C and A1442P) and WT LRRK2 fused to green fluorescent protein (GFP) and FLAG were transiently expressed in HEK293 cells using plasmid constructs. Western analysis and fluorescence microscopy consistently demonstrated lower mutant LRRK2 protein levels compared with WT. A time‐course expression study using flow cytometry showed that WT LRRK2 expression increased initially but then plateaued by 72 hr. Conversely, R1441C and A1442P mutant expression attained 85% and 74% of WT levels at 24 hr but fell to 68% and 55% of WT levels by 72 hr, respectively. We found that proteasome inhibition markedly increased mutant LRRK2 to levels approaching those of WT. Taken together, our findings reveal increased intracellular degradation for both mutants. Furthermore, the impact of mutant and WT LRRK2 expression on HEK293 cell viability was assessed under normative and oxidative (hydrogen peroxide) conditions and found not to differ. Expression of WT and mutant LRRK2 protein gave rise to intracellular aggregates of similar appearance and cellular localization. In summary, we provide evidence that the novel A1442P mutant and the previously investigated R1441C pathogenic mutant exhibit increased intracellular degradation, a property reportedly demonstrated for the pathogenic LRRK2 kinase domain mutant I2020T. © 2013 Wiley Periodicals, Inc.
