To evaluate the association between general self-efficacy and depression/anxiety among newly HIV-diagnosed Chinese men who have sex with men (MSM) in Beijing, our study evaluated the baseline survey data of MSM taking part in a clinical trial among Chinese MSM in Beijing. The baseline survey of the trial was conducted between March 2013 and March 2014. General self-efficacy and depression/anxiety were measured using standard scales. Logistic regression and cumulative logistic regression were used to evaluate the associations between general self-efficacy and depression/anxiety. A total of 367 newly HIV-diagnosed Chinese MSM in Beijing were recruited. There were negative associations between general self-efficacy and depression/anxiety among the study population. As general self-efficacy increased by one unit, the odds of “likely” or “borderline” depression versus normal, or “likely” depression versus “borderline” depression or normal decreased by 12% [adjusted odds ratio (AOR): 0.88, 95% confidence interval (CI): 0.85–0.92] after adjusting for potential confounders. Similarly, general self-efficacy was negatively associated with anxiety (AOR: 0.89, 95% CI: 0.86–0.93). A higher level of general self-efficacy was associated with lower levels of depression and anxiety among newly HIV-diagnosed Chinese MSM. Interventions promoting overall health and wellness should address self-efficacy, depression and anxiety.

Philosophiae Doctor - PhD / Semen analysis is the cornerstone for the investigation of male infertility. Semen quality can be influenced by geographical location, age, ejaculatory abstinence, and season. In 2010, the WHO published criteria for human semen characteristics that were markedly lower than those previously reported. Many reports have discussed the methodology used by the WHO to set the 2010 reference values. Some of the limitations of the WHO (2010) study included an undefined ejaculatory abstinence period, the limited representation of different age groups, and a limitation in geographical representation as the study did not include any data from Africa and Middle East. Therefore, the current cohort study was designed to provide retrospective data on semen quality (Africa and Middle East) and reproductive hormones (Middle East) in patients who underwent semen analysis and endocrine investigation at Andrology Laboratories in South Africa and Qatar.

Background: People who use drugs (PWUD) are disproportionately burdened by rates of HIV and Hepatitis C, more likely to experience stigma, social exclusion, and as a result, have poorer health outcomes. To mitigate these inequities in health, people with lived experience of drug use are, and should be, included in decisions that affect them. There is evidence that including PWUD in the development and delivery of harm reduction programs, services, and drug policy ensures such initiatives addresses their needs most effectively. As such, the purpose of this thesis is to present the findings of a scoping review of the peer-reviewed literature examining the involvement of people who use drugs (PWUD) in the development and delivery of harm reduction programs, services, and drug policy. Methods: Scoping reviews represent an increasingly popular method used to review the literature of a particular topic. It is a process of summarizing, or ‘mapping’, a range of evidence in order to convey the breadth and depth of a particular field. This scoping review implemented a search strategy focused on three categories: search terms that describe ‘peer engagement’, search terms that describe ‘substance use’ and finally search terms that describe ‘harm reduction programs/services/policy’. Searches of five academic electronic databases were conducted. Peer-reviewed literature published between 2010 and 2020 that discussed the involvement of PWUD in the development and/or delivery of harm reduction programs, services, or drug policy was included in the scoping review. Results: The search strategy produced a total of 1902 references. After duplicates were removed, thirty-two references met the inclusion criteria and were included for analysis. This scoping review identified five characteristics from each study: 1) type of study, 2) location of study, 3) year of publication, 4) type of engagement/participation, and 5) peer roles. Conclusion: One critical finding of this scoping review is the highest level of participation among PWUD was achieved when drug-user organizations were involved. / Graduate

We explored PrEP uptake in Mexico via an online survey completed by Spanish-speaking, Hornet geosocial networking application (GSN app) users without HIV (n = 2020). Most (81.3%) had heard of PrEP, 3.5% were current users, and 34.2% intended to take PrEP within six months. Current PrEP use was associated with PrEP eligibility (aOR 26.07 [95%CI 13.05–52.09], p < 0.001), recent STI testing (aOR 3.79 [95%CI 1.10–13.11], p = 0.035), and recent chemsex (aOR 3.02 [95%CI 1.02–8.93], p = 0.046). Recent STI testing was associated with hearing about PrEP from a doctor (aOR 3.26 [95%CI 1.98–5.36], p < 0.001), and those who lived in large cities were less likely to have learned about PrEP via Hornet (aOR 0.52 [95%CI 0.32–0.85], p = 0.009). Interventions to increase PrEP uptake in Mexico should build upon existing health networks and utilize GSN apps for PrEP information dissemination, particularly in less populated areas. / University of California / Revisión por pares

We evaluated participant, partner, and network factors associated with communication about condom use and HIV serostatus and explored their relationships with condomless anal intercourse (CAI) among 446 men who have sex with men (MSM) and 122 transgender women (TW) in Lima, Peru. Generalized estimating equations assessed contextual influences on communication and practices with recent sexual partners. More frequent HIV communication was reported by MSM who: identified as heterosexual, compared to bisexual or gay; characterized partnerships as stable, compared to casual, anonymous, or commercial; or discussed HIV/STIs with close social contacts (p < 0.05). TW in concurrent partnerships discussed condom use more frequently than those in monogamous relationships (p < 0.05). Condom use discussions and alcohol use among MSM were associated with CAI (p < 0.05). Findings highlight complexity in sexual decision-making and call for further study of conversation content and practices to inform HIV prevention messaging. / National Institutes of Health / Revisión por pares

Magister Public Health - MPH / Sub Saharan Africa (SSA) single-handedly accounted for approximately two thirds (196 000) of the world maternal deaths. High maternal deaths have been attributed to high prevalence of HIV and low uptake of Antenatal Care (ANC). This made World Health Organization (WHO) to recommend integration of Prevention of Mother to Child Transmission of HIV (PMTCT) services into ANC to improve accessibility and utilization. According to Zambia Ministry of Health (MoH), every pregnant woman should have her ANC registration in the first trimester and achieve eight visits by delivery time. With the extra need of PMTCT services in the women living with HIV, early and regular ANC attendance is emphasized. However, in Zambia, there is limited information on ANC uptake and its associated factors among women living with HIV. / 2023

Philosophiae Doctor - PhD / The incidence of Diffuse large B cell Lymphoma has been increasing lately at an alarming rate especially, in developing countries like Sudan. The standard therapy in Sudan is based solely on the R-CHOP chemotherapy regimen, yet it has been noticed that Diffuse Large B cell Lymphoma prognosis remains unfavorable. The late diagnosis and the consequent side-effects of the therapy directly affected the disease’s poor outcome. There is a scarcity of scientific publications regarding DLBCL in Sudan, but the increased burden necessitates the need for further research.

The World Health Organization (WHO) Framework Convention for Tobacco Control (FCTC) has prompted major change in tobacco control globally. However, policy implementation has been uneven, making 'smoke free' outcomes possible in some countries, but not others. We identify the factors that would improve implementation. We describe an ideal type of 'comprehensive tobacco control regimes', where policy environments are conducive to the implementation of tobacco control measures designed to eradicate tobacco use. The ideal type requires that a country have certain policy processes: the department of health takes the policy lead; tobacco is 'framed' as a public health problem; public health groups are consulted at the expense of tobacco interests; socioeconomic conditions are conducive to policy change; and, the scientific evidence is 'set in stone' within governments. No country will meet all these criteria in the short term, and the gap between the ideal type and the current state is wide in many countries. However, the WHO experience provides a model for progress.

Men who have sex with men continue to be at highest risk of HIV infection, with Black and Latino men who have sex with men [BLMSM] disproportionately at risk. The impact of alcohol consumption on condomless anal intercourse [CAI] is compounded for BLMSM by unique risk factors like internalized homophobia and racial stigma, reinforcing barriers to treatment. The traditional formats of existing HIV interventions fail to address heightened confidentiality concerns of BLMSM and few target both CAI and alcohol use. Existing interventions may be modified with mobile health [mhealth] technologies to improve outcomes for BLMSM. The current study examined the feasibility and acceptability of a novel mhealth intervention to reduce heavy drinking episodes [HDE], reduce CAI, and increase intentions to use pre-exposure prophylaxis medication [PrEP]. METHODS: Enrollment criteria included (1) Black and/or Latino man, (2) at least one episode of CAI with another man in the past six months, (3) at least one HDE in the past month and (4) no current PrEP use. Twelve participants completed a brief videoconferencing session then four weeks of interactive mobile messages. Outcome assessment was completed 8-weeks post-baseline. To assess feasibility and acceptability (primary outcomes), message response rates, ratings of intervention satisfaction (Client Satisfaction Questionnaire-8, CSQ), and ratings from a 10-item acceptability measure were used. RESULTS: Message response rates (M= 96%, SD = 0.04, Mdn = 98%) indicated high engagement. Ratings at follow-up indicated high acceptability (item rating M = 1.77, SD = 0.73, Mdn = 1.45; scores range from 1-5, lower ratings indicate higher acceptability) and high satisfaction (CSQ M = 26.7, SD = 4.08, Mdn = 27.5; scores range from 8-32, higher scores indicate higher satisfaction). Descriptive statistics were used to characterize post-intervention outcomes. HDEs decreased by 45% from baseline while PrEP use intentions remained largely unchanged (decreased by 5%). Only three of twelve participants reported CAI at post-intervention. DISCUSSION: Results show high engagement, acceptability, and satisfaction with the mhealth modality and support the feasibility of this approach to address HDE among BLMSM. Future efficacy testing of this novel mhealth intervention via randomized controlled trial is warranted.
