Methods: We collected secretion specimens of geni-tourinary tract from sexual partners who attended ourclinic during the period from May 1, 1999 to May 31,2000 and then detected Ct and Uu in the specimens. Results: The inconsistent rate of Ct and Uu infectedbetween sexual partners was 59.22% and 38.92%respectively. There were no correlations between pa-tients' age and the inconsistent rate of Ct and Uu in-fected (P>0.05). The most common inconsistency be-tween regular partners was seen in man with Ct infec-tion while in female with Uu infection; and in manwith concurrent infection of Ct while in female onlywith Uu; or in man with Ct infection while in female noCt and Uu were detected. Conclusion: The sexual transmitting ability of Ctand Uu is not as active as we have expected.展开更多

It is the base for accessing care and treatment programs, attains psycho-social support and reduces stigma, adheres to treatment and promotes safer health behavior particularly for couples. Objective: To assess HIV sero status disclosure to sexual partner and associated factors among HIV positive adult patient in Bale Zone hospitals. Method: A cross-sectional study design was conducted among 411 adult HIV positive clients who were selected by using systematic random sampling methods from Bale Zone Hospitals. Data were collected by using pre-tested questionnaire after verbal consent obtained from participants by trained nurse. Multiple logistic regression analysis was done by using SPSS version 20 and P-value of less than 0.05 was taken to declare statistical significance. Result: HIV sero status disclosure to sexual partners was 52.6%. Residence (AOR = 1.62;95% CI, 1.0, 2.60), receiving pre-test counselling related disclosure (AOR = 6.25;95% CI, 3.45, 11.33) and knowledge of partner’s HIV sero status (P-Value = 0.001) were significantly associated with HIV sero status disclosure. Fear of stigma and violence by sexual partner were the main reasons suggested for not disclosing HIV sero-status. Conclusion: The level of HIV sero-status disclosure to sexual partner was low. Disclosure of HIV sero status to sexual partner was significantly associated with clients’ place of residence, receiving pre-test counselling about disclosure and Knowledge of partners HIV sero status.展开更多

Hence, to reduce the risk of HIV transmission, there is need to understand the number, nature and variation in transition of sexual partners of men in living in slums. This paper uses India’s National Family Health Survey-3 data to estimate the variation in the type of sexual partners among sexually active men age 15 - 54 with more than one sexual partner in last 12 months prior to the survey in eight slums?of India. Among sexually active men, 1.3 percent reported having more than one sexual partner in the last 12 months prior to the survey. Men who are more likely to have two or more partners are those who are young, especially below age 25 years, never married, educated up to 5 years, and from middle class. There is a higher increase in the probability of sex with spouse from second last to the last sexual partner in non-slum areas than slum areas. However, in case of transition from other friends/relatives and female sex workers to spousal partners, there is a major decline in probability among non-slum men than slum men. These transitions are extremely important from the perspective of curbing the spread of HIV epidemic, especially in situations where women lack control over their own sexuality and seldom use condom in marital sex. Therefore, strategies focused in slums should either consider reducing men’s risky sexual behaviour or build capacities of women to negotiate safe sex in marital relationships or consider a combination of both.展开更多

The present analysis explores female partners＇ treatment preference for erectile dysfunction in Chinese Men. This was a phase 4, randomized, open-label, multicenter, crossover study in Chinese men with erectile dysfunction who were na＇fve to phosphodiesterase type 5 inhibitor treatments. Eligible patients were randomized to sequential 20-mg tadalafil/100-mg sildenafil or lO0-mg sildenafil/20-mg tadalafil for 8 weeks each. Of 418 patients, female partners of 64 patients agreed to enter the study; of 64 patients who entered the study with female partners, 63 were randomized, and 62 completed the study. Baseline demographics and disease characteristics were comparable between treatment groups. Significantly more couples preferred tadalafil compared with sildenafil overall （75.4% vs 24.6%; P〈 0.001）, and irrespective of erectile dysfunction severity at baseline （P 〈 0.005）. Significant improvements in sexual quality of life scores were reported at endpoint （Visit 8） in male patients and female partners in both tadalafil and sildenafil treatment groups （P 〈 0.001）. Significantly higher mean changes from baseline were observed for male patients in the tadalafil group compared with the sildenafil group for the erectile function （P = 0.013） and overall satisfaction （P = 0.019） International Index for Erectile Function domains and the spontaneity domain （P〈 0.001） of the Psychological and Interpersonal Relationship Scale. No major safety concerns were reported during the study. Though both treatments were effective, safe, and tolerable, more couples preferred tadalafil compared with sildenafil.展开更多

Although several strategies can reduce risk, some sexually experienced young women are choosing to abstain from sex for various reasons and periods of time following sexual debut, a practice known as secondary abstinence. However, others who desire to practice secondary abstinence find it difficult to do so. This qualitative study explored barriers that explained the dissonance between interest in secondary abstinence and continued sexual activity. In-depth interviews were conducted with 20 sexually-experienced African-American adolescent females, ages 18 - 23, who expressed interest in secondary abstinence. Partner-related barriers that created power imbalances presented the greatest challenges to becoming or remaining abstinent. Findings suggest that teaching young women how to recognize characteristics of healthy and unhealthy relationships, identify power imbalances, communicate assertively and develop positive coping skills can empower young women to build healthier relationships with their partners.展开更多

Evidence suggests however, that there is a gap in integrating evidence into practice and that relatively few cardiac patients receive sexual counseling. This can result in negative psychological, physical, and quality of life outcomes for couples who may needlessly decide sexual activity is too risky and cease all sexual activity. Two scientific statements now exist that provide ample guidance to health care providers in discussing this important topic. Using a team approach that includes physicians, nurses, physical therapists, rehabilitation staff, and others is important to ensure that sexual counseling occurs throughout recovery. In addition, several trials using interventional approaches for sexual counseling provide insight into successful approaches for sexual counseling in practice. This article provides practical strategies and evidence-based approaches for assessment and sexual counseling for all cardiac patients and their partners, and specific counseling for those with ischemic conditions, heart failure, and implanted devices.展开更多

This study examined the association between socio-demographic variables and knowing partners’ HIV status, multiple sex partners, and consistent condom use among 400 HIV-infected adults who had received ART for at least six months in Johannesburg, South Africa. The study used a cross-sectional survey and a structured interviewer administered questionnaire. Over half (n = 225, 56.3%) of participants were on ART for more than two years. Two thirds (n = 234, 63.2%) were aware of partner’s HIV status. Over a third (n = 136, 34.0%) reported having more than one sex partners. Three quarters (n = 279, 75.8%) reported consistent condom use with regular partner. Discussing HIV testing (aOR = 2.28, CI: 1.31 -3.95), awareness of partner’s HIV status (aOR = 2.59, CI: 1.50 -4.46), level of education (aOR = 0.64, CI: 0.42 -0.98), and duration on ART (aOR = 0.71, CI: 1.31 -3.95) were predictors for consistent condom use. Awareness of partner’s HIV status was associated with multiple partnership (aOR = 0.38, CI: 0.21 -0.66), living with partner (aOR = 4.75, CI: 2.86 -7.91), discussing HIV testing (aOR = 2.43, CI: 1.48 -3.99), and duration on ART (aOR = 2.04, CI: 1.43 -2.92). While gender (aOR = 5.68, CI: 3.46 -9.34), marital status (aOR = 0.44, CI: 0.25 -0.77), and awareness of partner’s HIV status (aOR = 0.52, CI: 0.30 -0.89) were associated with multiple partnerships. Risky sexual behaviours occurred in all types of partners and knowing partner’s HIV status was a predictor for consistent condom use with all types of partners. It is essential that HIV prevention strategies create an enabling environment for disclosure and reductions of risky sexual behaviours by HIV-infected persons on ART.展开更多

文摘目的了解男男性行为者(men who have sex with men,MSM)人群网络活动及相关因素。方法采用滚雪球抽样法,在固定场所进行MSM人群的招募和寻问式匿名问卷调查。结果在调查的400人中,87.8%常参与MSM相关互联网活动,网络活动目的41.9%为寻找性伴、31.9%为放松心理、14.5%为交友;认为网络对自己行为影响很大、较大分别为27.1%、27.9%,认为较小、很小分别为4.6%、2.5%;51.0%以网络进入MSM圈子,69.0%以网络寻找性伴。网络性伴平均年龄为(24.8±6.4)岁,低于其他性伴类型的(36.1±13.5)岁(t′=-7.808,P=0.000),年龄越小、文化程度越高网络性伴比例越大(χ2趋势=106.322、68.398,P均<0.01),学生及干部职员/其他职业、未婚、同性性取向者网络性伴较高(P均<0.01)。认识当地MSM朋友数≥6,近6月性伴居住城市数≥2,知晓HIV知识,来自咨询服务、来自互联网者网络性伴比例较多,HIV知识信息来自朋友者较少(P均<0.05)。首次性行为年龄越小、累计男性固定性伴数越多、近1周肛交次数越少者网络性伴比例越大(χ2趋势=15.903、32.802、13.583,P均<0.01);首次性行为对象为男性,近6月性伴数≤3、有男性固定性伴、有保护性主动肛交、有保护性被动肛交者网络性伴比例较大,有女性性行为、有女性固定性伴者网络性伴较少(P均<0.05)。结论 MSM网络活动极为普遍,网络对HIV防治的正面效应和负面作用互显,应针对性探索和加大更适合网络活动MSM特性的网络干预。
