[Needs of pre-exposure prophylaxis for HIV infection and related barriers among men who have sex with men].

Objective: To understand the actual needs for the pre-exposure prophylaxis (PrEP) for HIV infection and the factors hindering PrEP utilization in men who have sex with men (MSM). Methods: Participants were recruited by using MSM social application software Blued 6.5.0 and through MSM peer referral, sample size was 600. An electronic questionnaire survey was conducted anonymously with guidance of investigators via "Questionnaire Star" platform. The contents of the survey included demographic characteristics of the participants, the awareness of PrEP related knowledge, willingness and concerns about using PrEP, actual need for PrEP and self-efficacy of using PrEP. Results: A total of 622 MSM completed the survey, of whom 56.4% (351/622) and 4.3% (27/622) ever heard of and received PrEP, respectively. The need assessment of PrEP showed that 67.2% (418/622) of the participants had actual needs for PrEP and 21.2% (132/622) used PrEP with good self-efficacy. Structural equation modeling analysis showed that the awareness of PrEP related knowledge and concerning about PrEP utilization in MSM played a direct positive role in their self-efficiency of using PrEP, and the effect coefficients were 0.08 and 0.13, respectively. MSM self-discrimination indirectly affected the self-efficiency of using PrEP through concerns about PrEP use, the effect coefficient was 0.035. The result of generalized linear mixed model analysis demonstrated that the utilization of PrEP can improve the self-efficacy of using PrEP (OR=5.55), which increased by 0.14 times and 0.07 times with the increase of 1 score of the awareness of PrEP related knowledge and concern about using PrEP respectively. In addition, this survey found that in the participants, the main concerns about using PrEP were side effects, HIV prevention effect and its expense, accounting for 61.1% (380/622), 60.1% (374/622) and 53.2% (331/622), respectively. Most participants hoped to obtain PrEP services from CDC, MSM social organization and internet, accounting for 75.6% (470/622), 65.4% (407/622), and 63.8% (397/622), respectively. Conclusions: MSM showed difference of high need but low utilization of PrEP services. Low awareness of PrEP related knowledge, concerns about the prevention effect, side effects and expense of PrEP as well as self-discrimination were the factors hindering the use of PrEP in MSM. It is necessary to establish a suitable PrEP service model to meet the needs for PrEP in MSM.

Speaking the truth: an analysis of gender differences in serostatus disclosure practices among HIV-infected patients in St Petersburg, Russia.

The Russian HIV epidemic is primarily fuelled by injection drug use, but heterosexual spread may be playing an increasing role in transmission. Government-funded AIDS clinics provide most HIV treatment in Russia, and represent an important contact point between the medical community and infected population. Little is known about the population actively seeking HIV treatment. To describe demographics, perceived mode of acquisition and serostatus disclosure practices of HIV-infected individuals seeking treatment in St Petersburg, Russia, we conducted a cross-sectional study of 204 HIV-infected patients presenting to the St Petersburg City AIDS Center between May and June 2007. Mean age of respondents was 28 years old, 51% were women and two-thirds (67%) reported a history of injection drug use. Men were more likely to report injection (62% versus 45%) while women were more likely to identify sexual transmission (45% versus 32%) as their perceived infection route. Predictors of serostatus disclosure were female gender, married status and higher education. Women represent half of all patients seeking HIV treatment in St Petersburg, and are more likely than men to have disclosed their HIV-positive serostatus to sexual partners. While this population may not represent the burden of HIV disease in Russia, it is an important target group for secondary prevention.

A model of integrated primary care for HIV-positive patients with underlying substance use and mental illness.

There is a high burden of underlying substance use and mental illness in HIV-infected populations. HIV-care settings provide an important opportunity to assess substance and mental health needs among HIV-positive patients and to provide or make referrals for appropriate treatment services. In 2003, with funding from the Center for Substance Abuse Treatment (CSAT), we developed a model of integrated substance-use counselling and referral for treatment within a primary care HIV-care setting at The Miriam Hospital in Providence, Rhode Island. The project uses a multidisciplinary approach to provide linkage to treatment services for substance use and mental illness as well as to help participants with social service needs, such as housing and medical coverage, to ensure continuity of care and optimal HIV treatment adherence. Twelve percent of the 965 HIV-infected patients in care at our center have been enrolled in the project. Of these, all have a current substance-use disorder and 79.3% have been diagnosed with a mental illness. In addition, most participants are hepatitis C-positive (HCV) (65.5%). The majority of participants are on antiretroviral therapy (76.7%). Participants have been referred for the following treatment modalities: intensive outpatient services, methadone, buprenorphine, outpatient services and residential as well as individual and group counselling. Our model has been successful in assessing the substance-use and mental health needs of HIV-infected individuals with numerous co-morbidities and referring them for ancillary medical and social services.

Knowledge, attitude and practice survey regarding blood donation in a Northwestern Chinese city.

Recruitment of low-risk blood donors in developing countries is challenging. We studied the attitudes towards blood donation in several populations in a city in Western China. A survey of knowledge, attitude and practice was performed including 1280 individuals from eight distinct populations in Urumqi, Xinjiang Uyghur Autonomous Region, China. Included were Han Chinese and Uyghur populations of blood donors, non-donors, injection drug users, students and factory workers. Knowledge about blood donation varied between the groups. Factors motivating blood donation included social pressure, desire to know screening results and altruism. Inhibiting factors included fear of contracting an infection and other adverse health effects, including loss of vitality. Misconceptions about the effects of blood donation are widespread, even among educated persons in Urumqi. Fear of acquiring a serious infection may have been increased by the reports of HIV acquisition during plasma donations in China.
