广西农村暗娼安全套坚持使用情况及影响因素分析

目的 了解广西农村地区暗娼人群商业性行为时安全套使用情况及影响因素, 为制定暗娼艾滋病综合干预措施提供参考依据。 方法 采用多级抽样的方法,2019年4—6月在国家和省级暗娼哨点招募农村暗娼进行横断面问卷调查,调查内容包括场所位置、一般人口学信息、艾滋病知识、性行为特征及安全套使用等。用多因素非条件logistic 回归方法分析最近一个月坚持使用安全套的相关因素。 结果 2019年共调查农村暗娼1 350人,平均年龄(42.71±8.62)岁,艾滋病知识知晓率为95.63%(1 291/1 530),最近一次商业性性行为使用安全套比例为94.72%(1 274/1 345),最近一个月商业性性行为每次均使用安全套的比例为87.85%(1 186/1 350)。多因素非条件logistic 回归显示,知晓艾滋病知识(OR=14.857,95%CI:8.196～26.932)是安全套坚持使用的促进因素;交易场所为村屯(OR=0.180,95%CI:0.106～0.304)、30岁及以上年龄(30～岁组,OR=0.275,95%CI:0.090～0.841;50～岁组,OR=0.131,95%CI:0.042～0.407)是安全套坚持使用的障碍因素。 结论 应进一步加强对农村地区、大年龄暗娼人群安全套推广使用等综合干预力度。     

Periostin在妇科恶性肿瘤中的研究现状

骨膜蛋白(periostin)是近年被发现的一种多功能高分子糖蛋白,主要由成骨细胞及其前体细胞分泌,也可由肿瘤细胞及癌旁细胞分泌。该蛋白是一种高度保守的功能蛋白质,参与细胞外基质(ECM)的组成,并与肿瘤细胞黏附、转移和生长密切相关,属于分泌型可溶性ECM蛋白。periostin促进肿瘤细胞生存的分子机制及其与肿瘤发生、发展的关系具有重要理论意义,而且可为肿瘤的临床检测和治疗提供新靶点。笔者拟就periostin的结构与功能,periostin高表达在妇科恶性肿瘤发生、发展中的作用机制,在卵巢癌、宫颈癌、子宫内膜癌的初步研究,以及periostin为肿瘤治疗提供新靶点等的最新研究进展进行阐述。     

先天性生殖器官异常孕妇的围生结局分析

目的探讨先天性生殖器官异常孕妇的围生结局。方法选择2009年1月至2019年12月,于四川大学华西第二医院活产分娩的99779例单胎妊娠孕妇为研究对象。根据是否合并先天性生殖器官异常,将其分为观察组(n=324,合并)及对照组(n=99455,未合并)。回顾性分析2组孕妇的临床病例资料,总结观察组不同类型先天性生殖器官异常孕妇的围生结局特点。采用χ^(2)检验及独立样本t检验,对2组孕妇妊娠期各并发症发生率、剖宫产率及新生儿出生体重等,进行统计学分析。本研究遵循的程序符合2013年修订的《世界医学协会赫尔辛基宣言》要求。结果①观察组孕妇最常见先天性生殖器官异常前3位依次为纵隔子宫、单角/残角子宫及弓形子宫,分别占35.2%(114/324)、26.2%(85/324)及13.9%(45/324)。包括既往妊娠次数在内,观察组孕妇共计妊娠571次,其中弓形子宫、纵隔子宫孕妇的自然流产率位列前2位,分别为38.5%(35/91)、28.6%(61/213);阴道畸形孕妇足月产率(70.0%),高于子宫畸形者(52.8%),并且差异有统计学意义(χ^(2)=4.432、P=0.035)。②观察组孕妇早产、胎膜早破、胎位异常、胎盘早剥、胎儿生长受限(FGR)、胎盘黏连/植入、子宫破裂及剖宫产率分别为29.6%、29.3%、36.1%、5.9%、2.5%、21.0%、3.4%、78.7%,均分别高于对照组孕妇的9.8%、22.3%、5.7%、1.2%、1.0%、11.5%、1.5%、62.0%;而羊水过少率(0.9%)及新生儿出生体重[(2913±652)g],则显著低于对照组的2.9%、(3254±445)g,并且上述差异均有统计学意义(均为P<0.05)。2组孕妇前置胎盘、妊娠期高血压疾病(HDCP)、产后出血(PPH)及子宫切除率比较,差异均无统计学意义(P>0.05)。结论先天性生殖器官异常孕妇的母、胎围生期并发症发生风险高。提高该病孕妇的孕前及早孕期诊断率,加强围生期保健及处理,可改善其围生结局。     

生殖相关疾病与膳食炎症指数关系的研究进展

炎症参与了多囊卵巢综合征、子宫内膜异位症、妇科肿瘤等多种疾病的发生、发展,同时也可影响男性生殖功能。饮食在调节慢性炎症中发挥重要作用。膳食炎症指数（dietary inflammation index,DII）是一种新的临床膳食评估工具,将饮食分为促炎饮食和抗炎饮食,用于评估个人膳食整体的炎症潜力。研究显示,促炎饮食与生殖相关疾病的发生风险增加有关,抗炎饮食则与生殖相关疾病的发生风险降低有关。促炎饮食及其组分可升高机体内的炎症水平,促使慢性子宫内膜炎、多囊卵巢综合征、卵巢癌及子宫内膜癌等多种疾病的发生,也可对男性精子浓度和总活力等产生影响,从而导致不孕不育。综述DII与生殖相关疾病的关系和临床机制,并从疾病的预防和控制方面提出饮食建议,以期为临床治疗和护理提供参考。

Transient association between semen exposure and biomarkers of genital inflammation in South African women at risk of HIV infection

IntroductionSemen induces mucosal changes in the female reproductive tract to improve pregnancy outcomes. Since semen‐induced alterations are likely short‐lived and genital inflammation is linked to HIV acquisition in women, we investigated the contribution of recent semen exposure on biomarkers of genital inflammation in women at high HIV risk and the persistence of these associations.MethodsWe assessed stored genital specimens from 152 HIV‐negative KwaZulu‐Natal women who participated in the CAPRISA 008 trial between November 2012 and October 2014. During the two‐year study period, 651 vaginal specimens were collected biannually (mean five samples per woman). Cervicovaginal lavage (CVL) was screened for prostate‐specific antigen (PSA) by ELISA, whereas Y‐chromosome DNA (YcDNA) detection and quantification were conducted by RT‐PCR, representing semen exposure within 48 hours (PSA+YcDNA+) and semen exposure within three to fifteen days (PSA−YcDNA+). Soluble protein concentrations were measured in CVLs by multiplexed ELISA. T‐cell frequencies were assessed in cytobrushes by flow‐cytometry, and vulvovaginal swabs were used to detect common vaginal microbes by PCR. Linear mixed models adjusting for factors associated with genital inflammation and HIV risk were used to assess the impact of semen exposure on biomarkers of inflammation over multiple visits.ResultsHere, 19% (125/651) of CVLs were PSA+YcDNA+, 14% (93/651) were PSA−YcDNA+ and 67% (433/651) were PSA−YcDNA−. Semen exposure was associated with how often women saw their partners, the frequency of vaginal sex in the past month, HSV‐2 antibody detection, current gonorrhoea infection and Nugent Score. Both PSA detection (PSA+YcDNA+) and higher cervicovaginal YcDNA concentrations predicted increases in several cytokines, barrier‐related proteins (MMP‐2, TIMP‐1 and TIMP‐4) and activated CD4+CCR5+HLA‐DR+ T cells (β = 0.050; CI 0.001 to 0.098; p = 0.046) and CD4+HLA‐DR+ T cells (β = 0.177; CI 0.016 to 0.339; p = 0.032) respectively. PSA detection was specifically associated with raised pro‐inflammatory cytokines (including IL‐6, TNF‐α, IP‐10 and RANTES), and with the detection of BVAB2 (OR = 1.755; CI 1.116 to 2.760; p = 0.015), P. bivia (OR = 1.886; CI 1.102 to 3.228; p = 0.021) and Gardnerella vaginalis (OR = 1.815; CI 1.093 to 3.015; p = 0.021).ConclusionsMore recent semen exposure was associated with raised levels of inflammatory biomarkers and the detection of BV‐associated microbes, which declined by three to fifteen days of post‐exposure. Although transient, semen‐induced alterations may have implications for HIV susceptibility in women.     

Peyronie’s disease may negatively impact the sexual experience of a couple and female sexual function: a single center study

BackgroundPeyonie’s disease (PD) mostly affects males in the fifth decade of life, with a prevalence in the general population ranging between 0.5% and 20.3%. The pathology of PD is characterized by fibrosis of the tunic albuginea of the cavernous bodies of the penis, with the presence of pain in the erection and penile deformity. This is associated with decreased sexual function for both participants. The objective of the study was to investigate the influence of PD pathology on both male patients’ and their female partners’ sexual spheres, and analyze changes in sexual function and perception following penile correction surgery.MethodsProspective study, we included male patients with PD and their female partner sexually active. Patients underwent corporoplasty with multiple plications. The male and female sexuality was evaluated before surgery and three months after male treatment by the Female sexual Function Index (FSFI); International Index of Erectile Function (IIEF); Visual Analogical Scale (VAS).ResultsFrom January 2018 to November 2019 we included 35 couple. The female subjects before partner’s surgery presented dyspareunia, loss of sexual desire, inability to achieve orgasm, and sexual dissatisfaction. At three months after surgical treatment there was an improvement of sexual function in both male patients and female partners (desire P<0.0001, arousal P<0.0001, lubrification P<0.0001, orgasm P<0.0001, satisfaction P<0.0001, pain P<0.0001). As regarding male patients the pain decreased significantly (VAS score from 6 to 2.5), while there was no statistically significant improvement in erectile function (P=0.05).ConclusionsOur findings suggest that a viable approach to treatment of PD patients that involves their partners could lead to better functional and psychological results.     

Breast cancer among Danish women occupationally exposed to diesel exhaust and polycyclic aromatic hydrocarbons, 1964–2016

Objective:The aim of this study was to explore the association between occupational exposure to diesel exhaust and polycyclic aromatic hydrocarbons (PAH), respectively, and breast cancer subtypes.Methods:The study included 38 375 women <70 years with incident breast cancer, identified in the Danish Cancer Registry, and 5 breast cancer-free controls per case who were randomly selected from the Danish Civil Registration System and matched on year of birth. Full employment history was obtained for all study subjects from a nationwide pension fund, and exposure to diesel exhaust and PAH was assessed using a job exposure matrix. Conditional logistic regression was used for estimation of odds ratios (OR) with adjustment for reproductive factors and socioeconomic status.Results:No noteworthy associations were observed for overall breast cancer in women exposed to diesel exhaust. However, diesel exhaust modestly elevated the risk of estrogen receptor negative breast tumors before age 50 [OR 1.26, 95% confidence interval (CI) 1.09–1.46]. Duration– and dose–response relationships were further observed for this subtype in this age group. No notable risk patterns were generally observed for PAH exposure.Conclusion:Occupational exposure to diesel exhaust may increase the risk of early-onset estrogen receptor negative breast tumors in women. Future studies exploring this association are warranted.
