Adult male circumcision (AMC) reduces HIV transmission, but uptake is limited in part by current surgical methods. We randomized HIV-uninfected men (n = 138) to receive Shang Ring (SR)- or forceps-guided AMC from a locally trained surgeon. In as-treated analyses, more SR procedures were completed within 10 minutes (79% versus 0%, P < 0.01) and more subjects reported high satisfaction (77% versus 58%, P = 0.03). Healing time and pain scores were similar, though minor complication rates were highe ...[more]

Project description:BackgroundThe efficacy of voluntary male medical circumcision (VMMC) for human immunodeficiency virus (HIV) prevention in men was demonstrated in 3 randomized trials. This led to the adoption of VMMC as an integral component of the United States President's Emergency Plan for AIDS Relief (PEPFAR) combination HIV prevention program in sub-Saharan Africa. However, evidence on the individual-level effectiveness of VMMC programs in real-world, programmatic settings is limited.MethodsA cohort of initially uncircumcised, non-Muslim, HIV-uninfected men in the Rakai Community Cohort Study in Uganda was followed between 2009 and 2016 during VMMC scale-up. Self-reported VMMC status was collected and HIV tests performed at surveys conducted every 18 months. Multivariable Poisson regression was used to estimate the incidence rate ratio (IRR) of HIV acquisition in newly circumcised vs uncircumcised men.ResultsA total of 3916 non-Muslim men were followed for 17 088 person-years (PY). There were 1338 newly reported VMMCs (9.8/100 PY). Over the study period, the median age of men adopting VMMC declined from 28 years (interquartile range [IQR], 21-35 years) to 22 years (IQR, 18-29 years) (P for trend < .001). HIV incidence was 0.40/100 PY (20/4992.8 PY) among newly circumcised men and 0.98/100 PY (118/12 095.1 PY) among uncircumcised men with an adjusted IRR of 0.47 (95% confidence interval, .28-.78). The effectiveness of VMMC was sustained with increasing time from surgery and was similar across age groups and calendar time.ConclusionsVMMC programs are highly effective in preventing HIV acquisition in men. The observed effectiveness is consistent with efficacy in clinical trials and supports current recommendations that VMMC is a key component of programs to reduce HIV incidence.

Project description:Background:In Uganda, most-at-riskpopulations(MARPs) such as fishing communities remain vulnerable to preventable HIV acquisition. Safe Male Circumcision (SMC) has been incorporated into Uganda's HIV prevention strategies. This study aimed at determining SMC utilization and associated factors among adult men in a rural fishing community in Uganda. Methods:A cross-sectional study was conducted in a rural fishing village in central Uganda. Stratified random sampling of 369 fishermen aged 18-54 yearswas used according to their occupational category; fish monger, boat crew and general merchandise. The dependent variable wasutilization of SMC.A forward fitting multivariable logistic regression model was fitted with variables significant at p?0.05 controlling for confounding and effect modification. Results:Respondents'mean(SD) age was 30.0(9.3) years. Only8.4%hadSMC and among non-circumcised men, 84.9% had adequate knowledge of SMC benefits while 79.3% did not know were SMC services were offered. Peer support(AOR0.17;95%-CI0.05-0.60) and perceived procedural safety (AOR6.8;95%CI2.16-21.17) were independently associated with SMC utilization. Conclusion:In this rural fishing community, SMC utilization was low. These findings underscore the need to inform HIV preventionstrategies inthecontextof peer support and perceptionsheld by rural dwelling men.

Project description:BackgroundThe objective of the study was to compare rates of adverse events (AEs) related to male circumcision (MC) in HIV-positive and HIV-negative men in order to provide guidance for MC programs that may provide services to HIV-infected and uninfected men.Methods and findingsA total of 2,326 HIV-negative and 420 HIV-positive men (World Health Organization [WHO] stage I or II and CD4 counts > 350 cells/mm3) were circumcised in two separate but procedurally identical trials of MC for HIV and/or sexually transmitted infection prevention in rural Rakai, Uganda. Participants were followed at 1-2 d and 5-9 d, and at 4-6 wk, to assess surgery-related AEs, wound healing, and resumption of intercourse. AE risks and wound healing were compared in HIV-positive and HIV-negative men. Adjusted odds ratios (AdjORs) were estimated by multiple logistic regression, adjusting for baseline characteristics and postoperative resumption of sex. At enrollment, HIV-positive men were older, more likely to be married, reported more sexual partners, less condom use, and higher rates of sexually transmitted disease symptoms than HIV-negative men. Risks of moderate or severe AEs were 3.1/100 and 3.5/100 in HIV-positive and HIV-negative participants, respectively (AdjOR 0.91, 95% confidence interval [CI] 0.47-1.74). Infections were the most common AEs (2.6/100 in HIV-positive versus 3.0/100 in HIV-negative men). Risks of other complications were similar in the two groups. The proportion with completed healing by 6 wk postsurgery was 92.7% in HIV-positive men and 95.8% in HIV-negative men (p = 0.007). AEs were more common in men who resumed intercourse before wound healing compared to those who waited (AdjOR 1.56, 95% CI 1.05-2.33).ConclusionsOverall, the safety of MC was comparable in asymptomatic HIV-positive and HIV-negative men, although healing was somewhat slower among the HIV infected. All men should be strongly counseled to refrain from intercourse until full wound healing is achieved.Trial registrationhttp://www.ClinicalTrials.gov; for HIV-negative men #NCT00425984 and for HIV-positive men, #NCT000124878.

Project description:BackgroundOver the past decade, 15 high-priority countries in eastern and southern Africa have promoted voluntary medical male circumcision for human immunodeficiency virus (HIV) and sexually transmitted infection (STI) prevention. The prevalence of male circumcision in Uganda nearly doubled from 26% in 2011 to 43% in 2016, but remains below the 2020 target level. Little is known about how common male circumcision is perceived to be, how accurate such perceptions are, and whether they are associated with men's own circumcision uptake.MethodsWe conducted a cross-sectional study of all adult residents of eight villages in Rwampara District, southwestern Uganda in 2020-2022. We elicited their perceptions of the adult male circumcision prevalence within their village: >50% (most men), 10% to <50% (some), <10%, (few to none), or do not know. We compared their perceived norms to the aggregated prevalence of circumcision reported in these villages. We used a modified multivariable Poisson regression model to estimate the association between perceived norms and personal circumcision uptake among men.ResultsWe surveyed 1566 participants (91% response rate): 698 men and 868 women. Among the men, 167 (27%) reported being circumcised, including 167/444 (38%) men <50 years of age. Approximately one-fourth of the population (189 (27%) men and 177 (20%) women) believed that few to no men in their own village had been circumcised. In a multivariable regression model, men who underestimated the prevalence of male circumcision were less likely to be circumcised themselves (adjusted relative risk (aRR) = 0.51; 95% confidence interval (CI) = 0.37-0.83).ConclusionsIn this population-based study in rural Uganda, one-fourth of men underestimated the prevalence of male circumcision. Men who underestimated the extent of circumcision uptake were themselves less likely to be circumcised. If the observed association is causal and underestimates within the population contribute to low uptake, then interventions correcting these misperceived norms could increase uptake of voluntary medical male circumcision.

Project description:Medical male circumcision (MMC) has expanded in sub-Saharan Africa, yet uptake remains sub-optimal. We sought to understand women's perceptions of and influence on MMC in Rakai, Uganda. We conducted in-depth interviews with 27 women in fishing and trading communities, including women married to circumcised and uncircumcised men, single women, and sex workers. Data analysis followed a team-based framework approach. All female participants preferred circumcised men because of perceived reduced HIV and sexually transmitted infection (STI) risk, improved penile hygiene, and increased sexual pleasure. Perceived negative aspects included abstinence during wound healing, potentially increased male sexual risk behaviors, fear of being blamed for HIV acquisition, and economic insecurity due to time off work. Participants felt women could persuade their partners to be circumcised, accompany them to the clinic, refuse sex with uncircumcised men, and participate in community MMC activities. Findings support women's important role in MMC acceptance.

Project description:ObjectiveTo assess the safety, effectiveness and acceptability of the PrePex device for adult medical male circumcision (MMC) in routine service delivery in Kenya.MethodsWe enrolled 427 men ages 18-49 at one fixed and two outreach clinics. Procedures were performed by trained clinical officers and nurses. The first 50 enrollees were scheduled for six follow-up visits, and remaining men were followed at Days 7 and 42. We recorded adverse events (AEs) and time to complete healing, and interviewed men about acceptability and pain.ResultsPlacement and removal procedures each averaged between 3 and 4 minutes. Self-reported pain was minimal during placement but was fleetingly intense during removal. The rate of moderate/severe AEs was 5.9% overall (95% confidence interval [CI] 3.8%-8.5%), all of which resolved without sequelae. AEs included 5 device displacements, 2 spontaneous foreskin detachments, and 9 cases of insufficient foreskin removal. Surgical completion of MMC was required for 9 men (2.1%). Among the closely monitored first 50 participants, the probability of complete healing by Day 42 was 0.44 (95% CI 0.30-0.58), and 0.90 by Day 56. A large majority of men was favorable about their MMC procedure and would recommend PrePex to friends and family.ConclusionsThe PrePex device was effective for MMC in Kenya, and well-accepted. The AE rate was higher than reported for surgical procedures there, or in previous PrePex studies. Healing time is longer than following surgical circumcision. Provider experience and clearer counseling on post-placement and post-removal care should lead to lower AE rates.Trial registrationClinicalTrials.gov NCT01711411.

Project description:Male circumcision (MC) reduces the risk of heterosexual HIV acquisition in men by approximately 60%. MC programs for HIV prevention are currently being scaled-up in fourteen countries in sub-Saharan Africa. The current standard surgical technique for MC in many sub-Saharan African countries is the forceps-guided male circumcision (FGMC) method. The PrePex male circumcision (PMC) method could replace FGMC and potentially reduce MC programming costs. We compared the potential costs of introducing the PrePex device into MC programming to the cost of the forceps-guided method.Data were obtained from the Nyanza Reproductive Health Society (NRHS), an MC service delivery organization in Kenya, and from the Kenya Ministry of Health. Analyses are based on 48,265 MC procedures performed in four Districts in western Kenya from 2009 through 2011. Data were entered into the WHO/UNAIDS Decision Makers Program Planning Tool. The tool assesses direct and indirect costs of MC programming. Various sensitivity analyses were performed. Costs were discounted at an annual rate of 6% and are presented in United States Dollars.Not including the costs of the PrePex device or referral costs for men with phimosis/tight foreskin, the costs of one MC surgery were $44.54-$49.02 and $54.52-$55.29 for PMC and FGMC, respectively.The PrePex device is unlikely to result in significant cost-savings in comparison to the forceps-guided method. MC programmers should target other aspects of the male circumcision minimum package for improved cost efficiency.

Project description:Sub-Saharan African countries have substantially scaled-up safe male circumcision (SMC) services. However, it is unclear whether services are reaching men most at risk of HIV and whether there is behavioral disinhibition after SMC. We compared characteristics of SMC acceptors and nonacceptors in Rakai, Uganda.Cohort design.Through the Rakai Community Cohort Study, baseline characteristics of 587 non-Muslim men who subsequently accepted SMC were compared with those of 4907 uncircumcised non-Muslim men. Behaviors after SMC were compared with those of men who remained uncircumcised. Poisson multivariable regression was used to estimate adjusted prevalence rate ratios of behaviors in circumcised versus uncircumcised men.At baseline (pre-SMC), men subsequently circumcised were younger (mean = 26.1 years), as compared with the uncircumcised (mean = 28.5 years, P < 0.001), more likely to live in urban areas (21.1 versus 12.4%, P < 0.001), less likely to have been currently or previously married (36.5 versus 45.8%, P < 0.001) and more likely to report multiple sexual partners (48.3 versus 41.6%, P = 0.05) and genital discharge (7.4 versus 4.4%, P = 0.03). At follow-up (post-SMC), behaviors and genital discharge did not differ between the groups. Genital ulcers were less reported among circumcised (6.8%) compared with uncircumcised men (10.5%; adjusted prevalence rate ratios = 0.60, 95% confidence interval = 0.42-0.87, P = 0.007).In Rakai district, Uganda, the circumcision service program is attracting sexually active men at higher risk of HIV and we find no evidence of behavioral disinhibition following circumcision. The SMC program in this setting has the potential to reduce the HIV epidemic among men.

Project description:INTRODUCTION:Male circumcision (MC) is an effective intervention to reduce HIV acquisition in men in Africa. We conducted a cost analysis using longitudinal data on expenditures on services and community mobilization to estimate the marginal cost of MC over time and understand cost drivers during scale-up. METHODS:We used a time series with monthly records from 2008 to 2013, for a total of 72 monthly observations, from the Rakai MC Program in Uganda. Generalized linear models were used to estimate the marginal cost of an MC procedure. RESULTS:The marginal cost per MC in a mobile camp was $23 (P < 0.01) and in static facilities was $35 (P < 0.1). Major cost drivers included supplies in mobile camps with increasing numbers of surgeries, savings due to task shifting from physicians to clinical officers, and increased efficiency as personnel became more experienced. CONCLUSIONS:As scale-up continues, marginal costs may increase because of mobilization needed for less motivated late adopters, but improved efficiency could contain costs.

Project description:The PrePex circumcision device causes ischemic necrosis of the foreskin, raising concerns of anaerobic overgrowth. We compared the subpreputial microbiome of 2 men 7 days after PrePex device placement to that of 145 uncircumcised men in Rakai, Uganda, using 16S ribosomal (rRNA) RNA gene-based quantitative polymerase chain reaction analysis and sequencing. PrePex users had higher absolute abundance of all bacteria than uncircumcised men (P = .001), largely due to increased numbers of the following anaerobes: Porphyromonas (5.2 × 10(7) 16S rRNA gene copies/swab in the PrePex group and 1.1 × 10(6) 16S rRNA gene copies/swab in uncircumcised men; P = .002), Peptoniphilus (1.0 × 10(7) and 1.8 × 10(6) 16S rRNA gene copies/swab, respectively; P < .05), Anaerococcus (1.0 × 10(7) and 1.1 × 10(6) 16S rRNA gene copies/swab, respectively; P < .001), and Campylobacter ureolyticus (1.7 × 10(5) and 1.6 × 10(7)16S rRNA gene copies/swab, respectively; P < .001). The PrePex-associated increase in anaerobes may account for unpleasant odor and a possible heightened risk of tetanus.
