Trajectories of anxiety and depression among Chinese men who have sex with men on pre-exposure prophylaxis: a group-based trajectory model approach.

Background: Anxiety and depression can influence adherence to Pre-exposure Prophylaxis (PrEP). However, there is limited research on the temporal dynamics of anxiety and depression among men who have sex with men (MSM) using PrEP.

Methods: From December 2018 to November 2020, we administered the Hospital Anxiety and Depression Scale (HADS) to participants in the China Real-World Oral Intake of PrEP (CROPrEP) to measure their anxiety and depression levels.

Online distribution of HIV self-testing kits to promote HIV testing among men who have sex with men discontinuing pre-exposure prophylaxis after demonstration project completion in China: a multicentre open-label randomized controlled trial.

Background: HIV self-testing (HIVST) offers potential solutions to challenges associated with site-based HIV testing (SBHT). However, the effectiveness of HIVST as an HIV prevention strategy for men who have sex with men (MSM) discontinuing pre-exposure prophylaxis (PrEP) after the completion of PrEP demonstration project has rarely been assessed.

Methods: The China Real-world Study of Oral PrEP (CROPrEP) project was conducted in four cities in China.

Effectiveness and safety of community-led assisted partner service among HIV-diagnosed men who have sex with men: a multicentre, randomized controlled trial in China.

Background: No randomized controlled trials have involved established HIV-diagnosed men who have sex with men (MSM) diagnosed for more than 6 months into the assisted partner service (aPS). We compared voluntary aPS involving community-based organizations (CBOs) and HIV self-testing (aPSST) with regular partner service (rPS) in HIV-diagnosed MSM irrespective of diagnosis time.

Methods: In this unblinded, multicentre trial, we enrolled HIV-diagnosed MSM irrespective of diagnosis time in three cities in northern China.

High Human Papillomavirus Vaccine Acceptability and Cost-Effectiveness of the Chinese 2-Valent Vaccine Among Men Who Have Sex With Men: A Cross-Sectional Study in Shenyang, China.

Despite the insupportable burden caused by the human papillomavirus (HPV) and high vaccine acceptability, vaccination programs are not currently available for men who have sex with men (MSM). We aimed to assess HPV infection by examining the willingness for vaccination among MSM and cost-effectiveness of the Chinese 2-valent HPV vaccine. We recruited MSM in Shenyang, China between July and December 2020 to conduct anal HPV testing and an online survey regarding HPV-related knowledge and vaccine acceptability.

Prevention and control of HIV/AIDS in China: lessons from the past three decades.

In the past 37 years, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has undergone various major transmission routes in China, with the world most complex co-circulating HIV-1 subtypes, even the prevalence is still low. In response to the first epidemic outbreak of HIV in injecting drug users and the second one by illegal commercial blood collection, China issued the Anti-Drug Law and launched the Blood Donation Act and nationwide nucleic acid testing, which has avoided 98,232 to 211,200 estimated infections and almost ended the blood product-related infection. China has been providing free antiretroviral therapy (ART) since 2003, which covered >80% of the identified patients and achieved a viral suppression rate of 91%.

Assisted Partner Notification and Uptake of HIV Testing among Men Who Have Sex with Men: A Randomized Controlled Trial in China.

Background: Assisted partner notification (PN) is an effective approach for increasing HIV testing among heterosexual partners. There is sparse evidence on its effect among sexual partners of men who have sex with men (MSM).

Methods: A randomized controlled trial was conducted to compare the effect of assisted PN and passive PN interventions on uptake of HIV testing among male and female sexual partners of newly HIV-diagnosed MSM.

Disparity of human immunodeficiency virus incidence and drug resistance in college student, non-student youth and older men who have sex with men: a cross-sectional study from seven major cities of China.

Background: Human immunodeficiency virus (HIV) prevalence among student men who have sex with men (MSM) in college is more than 5.0% and keeps on increasing in China. This study aims to clarify the proportion of HIV recent infection, its propeller and the source among college student MSM.

Efficacy and cost-effectiveness of early antiretroviral therapy and partners' pre-exposure prophylaxis among men who have sex with men in Shenyang, China: a prospective cohort and costing study.

Background: Biomedical interventions such as antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP) are highly effective for prevention of human immunodeficiency virus (HIV) infection. However, China has not released national PrEP guidelines, and HIV incidence among men who have sex with men (MSM) is unchanged despite substantial scale-up of ART. We evaluated reductions in HIV transmission that may be achieved through early initiation of ART plus partners' PrEP.

Intimate Partner Violence Correlates With A Higher HIV Incidence Among MSM: A 12-Month Prospective Cohort Study in Shenyang, China.

Intimate partner violence (IPV) and HIV are highly prevalent worldwide among MSM. However, the association between IPV and HIV seroconversion is virtually unknown. This 12-month prospective cohort study was conducted among MSM in Shenyang, China to explore the causality between IPV and the incidence of HIV.

Poppers use and Sexual Partner Concurrency Increase the HIV Incidence of MSM: a 24-month Prospective Cohort Survey in Shenyang, China.

The use of poppers is highly prevalent in MSM, but little is known about the association between their use and HIV incidence in China. A prospective cohort study was conducted from 2011 to 2013 in MSM in Shenyang. 475(79.

Female and younger subjects have lower adherence in PrEP trials: a meta-analysis with implications for the uptake of PrEP service to prevent HIV.

Objective: To estimate the medicine-taking compliance (MTC) level, explore its facilitators and barriers, and quantify the association between MTC level and pre-exposure prophylaxis (PrEP) protective efficacy in individuals at risk of acquiring HIV being administered oral PrEP.

Design: Meta-analysis.

Data Sources: We searched PubMed, Cochrane and Embase databases for published randomized controlled trials (RCTs) pertaining to MTC of oral PrEP for HIV prevention up to 16 January 2017.

HIV Incidence and Care Linkage among MSM First-Time-Testers in Shenyang, China 2012-2014.

HIV testing is the first step to the fulfillment of Treat as Prevention (TasP) and reaching the 90-90-90 goal in HIV control. However, there are still a large number of Men who have Sex with Men (MSM) have never been tested for HIV before, and little is known about the HIV incidence and care linkage among this population. A Mixed method was used to recruit MSM who had never tested for HIV before from January 2012 to December 2014 in Shenyang, China.

Myeloid-Derived Suppressor Cells Associated With Disease Progression in Primary HIV Infection: PD-L1 Blockade Attenuates Inhibition.

Objective: Events occurring during the initial phase of human immunodeficiency virus (HIV) infection are intriguing because of their dramatic impact on the subsequent course of the disease. In particular, the relationship between myeloid-derived suppressor cells (MDSCs) and HIV pathogenesis in primary infection remains unknown and the mechanism of MDSCs in HIV infection are incompletely defined.

Methods: The frequency of MDSC expression in patients with primary HIV infection (PHI) and chronic HIV infection was measured, and the association with disease progression was studied.
