Disorders of sex development

Disorders of sex development (DSD) occur in 1–2/10,000 live births, with a specific molecular diagnosis only possible in 20% of cases. Presentation is usually at birth, and gender assignment must be avoided before review by an expert multidisciplinary team. Initial investigations allow a working diagnosis to be made within 48 hr. In 46,XY DSD, surgery may be necessary to correct hypospadias, reposition or remove undescended testes, and remove symptomatic Müllerian remnants. In 46,XX DSD, feminizing surgery is performed less frequently than in the past, but genitoplasty may still be indicated. Psychosocial support is required to promote positive adaptation as gender dissatisfaction can occur in certain conditions. Long-term outcome data are sparse.     

Association between de novo lipogenesis susceptibility genes and coronary artery disease

Background and aimsCoronary artery disease (CAD) is the principal cause of death in individuals with non-alcoholic fatty liver disease (NAFLD). The aim of this study was to use genetic epidemiology to study the association between de novo lipogenesis (DNL), one of the major pathways leading to NAFLD, and CAD risk.Methods and resultsDNL susceptibility genes were used as instruments and selected using three approaches: 1) genes that are associated with both high serum triglycerides and low sex hormone-binding globulin, both downstream consequences of DNL (unbiased approach), 2) genes that have a known role in DNL (biased approach), and 3) genes that have been associated with serum fatty acids, used as a proxy of DNL. Gene-CAD effect estimates were retrieved from the meta-analysis of CARDIoGRAM and the UK Biobank (～76014 cases and ～264785 controls). Effect estimates were clustered using a fixed-effects meta-analysis. Twenty-two DNL susceptibility genes were identified by the unbiased approach, nine genes by the biased approach and seven genes were associated with plasma fatty acids. Clustering of genes selected in the unbiased and biased approach showed a statistically significant association with CAD (OR:1.016, 95%CI:1.012; 1.020 and OR:1.013, 95%CI:1.007; 1.020, respectively), while clustering of fatty acid genes did not (OR:1.004, 95%CI:0.996–1.011). Subsequent exclusion of potential influential outliers did reveal a statistically significant association (OR:1.009, 95%CI:1.000; 1.018).ConclusionsDNL susceptibility genes are associated with an increased risk of CAD. These findings suggest that DNL may be involved in the pathogenesis of CAD and favor further development of strategies that target NAFLD through DNL.     

性服务工作者性病和艾滋病的干预研究

目的 了解性工作者的性病/艾滋病知识、态度、信念、行为等现状,积极探索对该人群进行预防性病、艾滋病及行为干预的有效办法,为今后在更大范围的高危人群中进行干预提供科学依据.方法 成立专职高危干预队伍,设计借鉴其他地区经验,深入目标人群进行系列外展服务,利用干预前后封闭式调查问卷评价干预效果.结果 发放干预前后问卷各522份,收回前后有效问卷387份.通过外展服务,娱乐场所从业人员对性病史滋病预防知识知晓率明显提高,对安全套及安全性行为预防性病艾滋病的传播的信念和态度有明显转变.结论 对娱乐场所从业人群开展系列专业外展服务可以提高该人群的防病意识,提升对性病史滋痛的知晓率,是高危人群干预的有效方法.     

唐县针对暗娼艾滋病高危人群干预模式效果分析

目的通过对唐县干预实施过程的分析总结,探讨县级娱乐服务场所暗娼(CSW)的干预措施。方法收集整理唐县干预实施过程中的相关资料,总结干预的方法步骤,分析影响干预的相关因素,提出干预工作中遇到的问题和解决的方法对策。结果78.57%的高危场所接受干预,其中高、中档娱乐服务场所接受干预率为100%,低档场所接受干预率62.5%。CSW接受干预人数占96.66%。与基线调查统计结果相比,CSW艾滋病知识知晓率从60%上升到95%,其中高、中档场所CSW艾滋病知识知晓率为100%,低档场所CSW知晓率为82.5%;安全套使用率由50%上升到86%,其中高、中档场所CSW安全套使用率均为100%,低档场所CSW安全套使用率为53.1%。接受HIV初筛检测率为49.53%。培养了一支同伴教育宣传员队伍。结论“依据出租车司机线索,直接拜访老板,逐一走访高危场所,培养同伴教育宣传员,定期外展现场干预与定期集中培训交流相结合”的唐县CSW干预模式,启动、推动了唐县的干预工作,使干预工作能够循环、持续、深入进行,在高危人群CSW中宣传普及艾滋病防治知识、推广100%安全套使用技术、营造社会支持环境等方面起到了重要的作用,有效防止了当地艾滋病的传播。
