RESUMO

PURPOSE OF REVIEW: Since 2007, voluntary medical male circumcision (VMMC) programs have been associated with substantially reduced HIV incidence across 15 prioritized countries in Eastern and Southern Africa. Drawing on the programmatic experience of global VMMC leaders, this report reviews progress made in the first 15 years of the program, describes programmatic and research gaps, and presents considerations to maximize the impact of VMMC. RECENT FINDINGS: Overall, key programmatic and research gaps include a lack of robust male circumcision coverage estimates due to limitations to the data and a lack of standardized approaches across programs; challenges enhancing VMMC uptake include difficulties reaching populations at higher risk for HIV infection and men 30 years and older; limitations to program and procedural quality and safety including variations in approaches used by programs; and lastly, sustainability with limited evidence-based practices. Considerations to address these gaps include the need for global guidance on estimating coverage, conducting additional research on specific sub-populations to improve VMMC uptake, implementation of responsive and comprehensive approaches to adverse event surveillance, and diversifying financing streams to progress towards sustainability. This report's findings may help establish a global VMMC research and programmatic agenda to inform policy, research, and capacity-building activities at the national and global levels.

RESUMO

The World Health Organization identified men as an essential group to target with HIV testing and treatment strategies;: men who have sex with men (MSM) and male clients of female sex workers (CFSW) account for 35% of new HIV infections globally. Using a cross-sectional design from a community-based HIV prevention project in Tanzania (October 2015-September 2018) and multivariable logistic regression, we identified predictors of HIV seropositivity among men. Of 1,041,343 men on their initial visit to the project, 36,905 (3.5%) were MSM; 567,005 (54.5%) were CFSW; and 437,343 (42.0%) were other men living near hotspots (OMHA). Three predictors of HIV seropositivity emerged across all three groups: being uncircumcised, having sexually transmitted infection symptoms, and harmful drinking of alcohol before sex. Any reported form of gender-based violence among MSM and OMHA and inconsistent condom use among CFSW were associated with HIV seropositivity. These findings may inform community HIV strategies like self-testing, delivery of pre-exposure prophylaxis and antiretroviral therapy, and behavioral change communication targeting men at higher risk of infection.

RESUMO

BACKGROUND: For malnourished patients with end stage renal disease (ESRD) on hemodialysis (HD), refeeding is complex; true weight (dry weight) gain must be accounted for as it accrues to safely dialyze. OBJECTIVE: This case describes the challenge of following true weight to appropriately adjust treatment for a patient with ESRD on HD requiring inpatient refeeding. METHODS: A 17-year-old female presented to an adolescent clinic after referral from her nephrologist for malnutrition and disordered eating. Her weight was 38.3 kg and height was 155.2 cm (76.2% of mean estimated body mass index, MEBMI). Her history was remarkable for a diagnosis of ESRD. The patient was admitted to the inpatient disordered eating program. The patient continued HD three times a week and was followed by nephrology. The team noted that the patient's dry weight for dialysis had not yet been adjusted, leading to increasingly aggressive dialysis. The nephrology team addressed the need for reassessments of dry weight by utilizing the "crit line" method. RESULTS: Frequent assessment allowed the nephrology team to account for intensive renourishment of the patient. After a 64 day hospital stay, the patient achieved 88.1% of MEBMI, calculated using her most up to date dry weight. CONCLUSION: Among patients with malnutrition and ESRD requiring HD, it is imperative to determine a patient's dry weight at the beginning of refeeding so the treatment plan can be adjusted according to the dynamic, true weight of the patient. This case illustrates the importance of interdisciplinary teamwork when managing a patient with malnutrition and ESRD on HD.

RESUMO

Male circumcision (MC) is a key HIV prevention intervention for men in countries with high HIV prevalence. Women's understanding of MC is important but poorly understood. We conducted a systematic review including women's knowledge of MC's biomedical impacts and its association with female sexual satisfaction and function through October 2017. Thirty-eight articles were identified: thirty-two with knowledge outcomes, seven with sexual satisfaction, and four with sexual function (N = 38). Respondent proportions aware MC protects men from HIV were 9.84-91.8% (median 60.0%). Proportions aware MC protects men from STIs were 14.3-100% (72.6%). Proportions aware MC partially protects men from HIV were 37.5-82% (50.7%). Proportions aware MC is not proven to protect women from infection by an HIV-positive partner were 90.0-96.8% (93.0%). No increases over time were noted. Women's MC knowledge is variable. Education could help women support MC and make better-informed sexual decisions.

RESUMO

A growing evidence base supports expansion of partner notification in HIV testing services (HTS) in sub-Saharan Africa. In 2015, a cross-sectional study was conducted in Njombe region, Tanzania, to evaluate partner notification within facility-based HTS. Men and women newly diagnosed with HIV were enrolled as index clients and asked to list current or past sexual partners for referral to HTS. Successful partner referral was 2.5 times more likely among married compared to unmarried index clients and 2.2 times more likely among male compared to female index clients. In qualitative analysis, male as well as female index clients mentioned difficulties notifying past or casual partners, and noted disease symptoms as a motivating factor for HIV testing. Female index clients mentioned gender-specific challenges to successful referral. Women may need additional support to overcome challenges in the partner notification process. In addition to reducing barriers to partner notification specific to women, a programmatic emphasis on social strengths of males in successfully referring partners should be considered.

RESUMO

To meet UNAIDS' 90-90-90 treatment goals, effective approaches to HIV testing services (HTSs) are urgently needed. In 2015, a cross-sectional study was conducted to evaluate effectiveness and feasibility of partner notification for HTS in Tanzania. Men and women newly diagnosed with HIV were enrolled as index clients, listed sexual partners, and given options to notify and link their partners to HTS. Of 653 newly diagnosed individuals, 390 index clients were enrolled, listed 438 sexual partners, of whom 249 (56.8%) were successfully referred. Of 249 partners reaching the facilities, 96% tested for HIV, 148 (61.9%) tested HIV+ (all newly diagnosed), and 104 (70.3%) of partners testing positive were enrolled into HIV care and treatment. Results showed good acceptability, feasibility and effectiveness, as evidenced by high uptake of partner notification among newly diagnosed individuals, over half of listed partners successfully referred, and a very high positivity rate among referred sexual partners.

RESUMO

BACKGROUND: Voluntary medical male circumcision (VMMC) reduces HIV acquisition among heterosexual men by approximately 60%. VMMC is a surgical procedure and some adverse events (AEs) are expected. Swaziland's Ministry of Health established a toll-free hotline to provide general information about VMMC and to manage post-operative clinical AEs through telephone triage. METHODS: We retrospectively analyzed a dataset of telephone calls logged by the VMMC hotline during a VMMC campaign. The objectives were to determine reasons clients called the VMMC hotline and to ascertain the accuracy of telephone-based triage for VMMC AEs. We then analyzed VMMC service delivery data that included date of surgery, AE type and severity, as diagnosed by a VMMC clinician as part of routine post-operative follow-up. Both datasets were de-identified and did not contain any personal identifiers. Proportions of AEs were calculated from the call data and from VMMC service delivery data recorded by health facilities. Sensitivity analyses were performed to assess the accuracy of phone-based triage compared to clinically confirmed AEs. RESULTS: A total of 17,059 calls were registered by the triage nurses from April to December 2011. Calls requesting VMMC education and counseling totaled 12,492 (73.2%) and were most common. Triage nurses diagnosed 384 clients with 420 (2.5%) AEs. According to the predefined clinical algorithms, all moderate and severe AEs (153) diagnosed through telephone-triage were referred for clinical management at a health facility. Clinicians at the VMMC sites diagnosed 341 (4.1%) total clients as having a mild (46.0%), moderate (47.8%), or severe (6.2%) AE. Eighty-nine (26%) of the 341 clients who were diagnosed with AEs by clinicians at a VMMC site had initially called the VMMC hotline. The telephone-based triage system had a sensitivity of 69%, a positive predictive value of 83%, and a negative predictive value of 48% for screening moderate or severe AEs of all the AEs. CONCLUSIONS: The use of a telephone-based triage system may be an appropriate first step to identify life-threatening and urgent complications following VMMC surgery.

RESUMO

Introduction: In 2016, UNAIDS set ambitious targets to reduce global HIV infections by 75% by 2020 and 90% by 2030, based on the 2.1 million new infections reported in 2010. However, by 2022, new HIV infections had only decreased by 38%, from 2.1 million in 2010 to 1.3 million in 2022, raising concerns about reaching the 2030 goal. Female sex workers (FSWs) in sub-Saharan Africa face a disproportionately high risk of HIV acquisition, contributing 5%-20% of all new infections in several countries in the region. This analysis investigates HIV seroconversion and associated factors among FSWs, offering insights into critical interventions for preventing HIV transmission in this population and advancing the goal of ending the HIV pandemic by 2030. Methods: We conducted a retrospective cohort study involving 17,977 FSWs who initially tested HIV negative upon enrollment in the Sauti project between October 2016 and September 2018. HIV incidence rates were calculated by dividing the number of new HIV cases by observed person-time within the cohort. Cox regression analysis identified factors associated with seroconversion. Results: The study revealed an HIV incidence rate of 8.6 per 100 person-years among FSWs [95% confidence interval (CI): 8.1-9.1]. Factors independently associated with HIV seroconversion included age 35 years or older [adjusted hazard ratio (aHR): 2.53; 95% CI: 2.03-3.14], unprotected sex (aHR: 1.27; 95% CI: 1.13-1.42), STI symptoms (aHR: 1.99; 95% CI: 1.67-2.38), and alcohol consumption before sex (aHR: 1.20; 95% CI: 1.07-1.34). Conclusion: Targeted interventions are vital in curbing HIV transmission among FSWs, with a focus on expanding access to primary HIV prevention services, particularly for older FSWs who face heightened risk. Tailored sexual health education programs are imperative to encourage consistent condom use and enable informed decision-making. Accessible and timely STI screening and treatment services are crucial to mitigate HIV transmission risk. Collaborative partnerships between healthcare providers, community organizations, and government agencies are essential in implementing these interventions among FSWs.

RESUMO

Introduction: Adolescent girls and young women (AGYW) continue to experience a high incidence of HIV in southern and eastern Africa, even in the context of large-scale HIV prevention interventions. In Tanzania, AGYW account for the largest proportion of new infections and have a higher risk of HIV acquisition than males of comparable age. Methods: We used routinely collected data from the PEPFAR/USAID-funded Sauti Project, a large combination HIV prevention program, to examine the relationship between transactional sex and sex with older partners among AGYW in Tanzania (2015-2020). Out-of-school AGYW 15-24 years completed a vulnerability index and were tested for HIV. We estimated weighted prevalence ratios (PR) and 95% confidence intervals (CI) for the associations of transactional sex (sex exchanged for money/services/gifts outside of sex work) and sex with older partners (≥5-years older, ≥10-years older) with prevalent HIV. Age cutoffs of 5 and 10 years were used to align partner age differences with age-disparate and intergenerational sex, respectively. We assessed potential synergism between exposures, and subgroup analyses explored associations among girls 15-19. Results: Sixty seven thousand three hundred fifty seven AGYW completed the vulnerability index and 14,873 had captured HIV testing records. Median age was 20 years (IQR 18-22). Transactional sex and age-disparate sex were common (35% and 28%, respectively); 13% of AGYW reported both behaviors. HIV prevalence was associated with both transactional sex (PR: 1.28; 95% CI 1.00-1.63) and age-disparate sex (PR:1.26, 95% CI 0.99-1.60). In common referent analysis, transactional sex remained strongly associated with HIV, even in the absence of age-disparate sex (PR 1.41; 95% CI 1.02-1.94). Discussion: Evidence of statistical synergism was not present, suggesting both transactional sex and age-disparate sex operate through similar pathways to increase HIV risk. Increased specificity within HIV prevention programs is needed to better meet the sexual and reproductive health needs of AGYW at high risk of HIV in Tanzania, including investment in tailored youth-friendly strategies for AGYW who have been marginalized from the current HIV response.

RESUMO

PURPOSE: Voluntary medical male circumcision decreases the risk in males of HIV infection through heterosexual intercourse by about 60% in clinical trials and 73% at post-trial followup. In 2007 WHO and the Joint United Nations Programme on HIV/AIDS (UNAIDS) recommended that countries with a low circumcision rate and high HIV prevalence expand voluntary medical male circumcision programs as part of a national HIV prevention strategy. Devices for adult/adolescent male circumcision could accelerate the pace of scaling up voluntary medical male circumcision. Detailed penile measurements of African males are required for device development and supply size forecasting. MATERIALS AND METHODS: Consenting males undergoing voluntary medical male circumcision at 3 health facilities in the Iringa region, Tanzania, underwent measurement of the penile glans, shaft and foreskin. Age, Tanner stage, height and weight were recorded. Measurements were analyzed by age categories. Correlations of penile parameters with height, weight and body mass index were calculated. RESULTS: In 253 Tanzanian males 10 to 47 years old mean ± SD penile length in adults was 11.5 ± 1.6 cm, mean shaft circumference was 8.7 ± 0.9 cm and mean glans circumference was 8.8 ± 0.9 cm. As expected, given the variability of puberty, measurements in younger males varied significantly. Glans circumference highly correlated with height (r = 0.80) and weight (r = 0.81, each p <0.001). Stretched foreskin diameter moderately correlated with height (r = 0.68) and weight (r = 0.71, each p <0.001). CONCLUSIONS: Our descriptive study provides penile measurements of males who sought voluntary medical male circumcision services in Iringa, Tanzania. To our knowledge this is the first study in a sub-Saharan African population that provides sufficiently detailed glans and foreskin dimensions to inform voluntary medical male circumcision device development and size forecasting.

RESUMO

Eating disorders are common, chronic illnesses that frequently arise during adolescence. Because of the impact on nutrition, individuals with eating disorders have significant health consequences, including effects on reproductive health. Adolescent women with eating disorders frequently have menstrual irregularities, though the causes of these abnormalities are complex and vary depending on the type of eating disorder. Teens with eating disorders may have changes in current and future fertility, and eating disorders during pregnancy can have medical and psychologic impacts for both mother and child. Though not well researched, eating disorders in men can affect reproductive health and potentially impact fertility. Lastly, eating disorders in adolescents can have significantly deleterious, irreversible effects on bone health.

RESUMO

The government of Tanzania has adopted voluntary medical male circumcision (VMMC) as an important component of its national HIV prevention strategy and is scaling up VMMC in eight regions nationwide, with the goal of reaching 2.8 million uncircumcised men by 2015. In a 2010 campaign lasting six weeks, five health facilities in Tanzania's Iringa Region performed 10,352 VMMCs, which exceeded the campaign's target by 72%, with an adverse event (AE) rate of 1%. HIV testing was almost universal during the campaign. Through the adoption of approaches designed to improve clinical efficiency-including the use of the forceps-guided surgical method, the use of multiple beds in an assembly line by surgical teams, and task shifting and task sharing-the campaign matched the supply of VMMC services with demand. Community mobilization and bringing client preparation tasks (such as counseling, testing, and client scheduling) out of the facility and into the community helped to generate demand. This case study suggests that a campaign approach can be used to provide high-volume quality VMMC services without compromising client safety, and provides a model for matching supply and demand for VMMC services in other settings.

RESUMO

Voluntary medical male circumcision (VMMC) reduces female-to-male HIV transmission by approximately 60%; modeling suggests that scaling up VMMC to 80% of men 15- to 49-years-old within five years would avert over 3.3 million new HIV infections in 14 high priority countries/regions in southern and eastern Africa by 2025 and would require 20.33 million circumcisions. However, the shortage of health professionals in these countries must be addressed to reach these proposed coverage levels. To identify human resource approaches that are being used to improve VMMC volume and efficiency, we looked at previous literature and conducted a program review. We identified surgical efficiencies, non-surgical efficiencies, task shifting, task sharing, temporary redeployment of public sector staff during VMMC campaign periods, expansion of the health workforce through recruitment of unemployed, recently retired, newly graduating, or on-leave health care workers, and the use of volunteer medical staff from other countries as approaches that address human resource constraints. Case studies from Kenya, Tanzania, and Swaziland illustrate several innovative responses to human resource challenges. Although the shortage of skilled personnel remains a major challenge to the rapid scale-up of VMMC in the 14 African priority countries/regions, health programs throughout the region may be able to replicate or adapt these approaches to scale up VMMC for public health impact.

RESUMO

Following WHO's 2015 recommendation, countries in sub-Saharan Africa have progressively scaled up oral pre-exposure prophylaxis (PrEP) as part of combination HIV prevention. PrEP has potential to significantly reduce new HIV infections in sub-Saharan Africa if it is widely available, accessible, and effectively used. Initial scale-up efforts have generated progress, drawing lessons from existing HIV interventions, such as antiretroviral therapy and biomedical prevention. However, beset by unprepared health systems, scale-up has been slow, resulting in suboptimal coverage among priority groups at higher risk of HIV acqusition. Using the WHO health system building blocks framework, this Review synthesises literature on essential considerations for PrEP scale-up in sub-Saharan Africa, highlighting the importance of health system adaptability and responsiveness.

RESUMO

INTRODUCTION: Evidence indicates HIV oral pre-exposure prophylaxis (PrEP) is highly efficacious and effective. Substantial early discontinuation rates are reported by many programs, which may be misconstrued as program failure. However, PrEP use may be non-continuous and still effective, since HIV risk fluctuates. Real-world PrEP use phenomena, like restarting and cyclical use, and the temporal characteristics of these use patterns are not well described. The objective of our study was to characterize and identify predictors of use patterns observed in large PrEP scale-up programs in Africa. METHODS: We analysed demographic and clinical data routinely collected during client visits between 2017 and 2019 in three Jhpiego-supported programs in Kenya, Lesotho and Tanzania. We characterized duration on/off PrEP and, using ordinal regression, modelled the likelihood of spending additional time off and identified factors associated with increasing cycle number. The Andersen-Gill model was used to identify predictors of time to PrEP discontinuation. To analyse factors associated with a client's first return following initiation, we used a two-step Heckman probit. RESULTS: Among 47,532 clients initiating PrEP, approximately half returned for follow-up. With each increase in cycle number, time off PrEP between use cycles decreased. The Heckman first-step model showed an increased probability of returning versus not by older age groups and among key and vulnerable population groups versus the general population; in the second-step model older age groups and key and vulnerable populations were less likely in Kenya, but more likely in Lesotho, to return on-time (refill) versus delayed (restarting). CONCLUSIONS: PrEP users frequently cycle on and off PrEP. Early discontinuation and delays in obtaining additional prescriptions were common, with broad predictive variability noted. Time off PrEP decreased with cycle number in all countries, suggesting normalization of use with experience. More nuanced measures of use are needed than exist for HIV treatment if effective use of PrEP is to be meaningfully measured. Providers should be equipped with measures and counselling messages that recognize non-continuous and cyclical use patterns so that clients are supported to align fluctuating risk and use, and can readily restart PrEP after stopping, in effect empowering them further to make their own prevention choices.

RESUMO

Oral pre-exposure prophylaxis (PrEP) is an efficacious way to lower the risk of HIV acquisition among high-risk individuals. Despite the World Health Organization's 2015 recommendation that all persons at substantial risk of HIV infection be provided with access to oral PrEP, the rollout has been slow in many low- and middle-income countries. Initiatives for national rollout are few, and subtle skepticism persists in several countries about the feasibility of national PrEP implementation. We describe the conceptual design of the Jilinde project, which is implementing oral PrEP as a routine service at a public health scale in Kenya. We describe the overlapping domains of supply, demand, and government and community ownership, which combine to produce a learning laboratory environment to explore the scale-up of PrEP. We describe how Jilinde approaches PrEP uptake and continuation by applying supply and demand principles and ensures that government and community ownership informs policy, coordination, and sustainability. We describe the "learning laboratory" approach that informs strategic and continuous learning, which allows for adjustments to the project. Jilinde's conceptual model illustrates how the coalescence of these concepts can promote scale-up of PrEP in real-world conditions and offers critical lessons on an implementation model for scaling up oral PrEP in low- and middle-income countries.

RESUMO

Adolescent girls and young women (AGYW) aged 15 to 24 years face disproportionately high risks of acquiring HIV and other sexually transmitted infections (STIs). A sexual health risk stratification tool can support the development and implementation of tailored HIV and STI prevention services for sub-groups of at-risk AGYW. Data were collected among sexually active AGYW aged 15 to 24 years in Tanzania between April 2015 and March 2017. Exploratory and confirmatory factor analyses were conducted to construct and assess the latent structure of a ten-item scale for rapid assessment of sexual health risks. Items with high factor loadings and minimal cross loadings were retained in the final scale. Scale performance was appraised against condomless sex (defined as unprotected vaginal or anal intercourse) reported by AGYW for construct validity. A three-factor structure of vulnerability to HIV among AGYW was supported with subscales for socioeconomic vulnerability; lack of adult support; and sexual behavioral risks. The chi-square goodness-of-fit test, root mean square error of approximation, comparative fit index, and Tucker-Lewis index indicated a strong goodness-of-fit of the three-factor scale. Cronbach alphas (0.55 for socioeconomic vulnerability, 0.55 for lack of support, and 0.48 for sexual risk) indicated sub-optimal internal consistency for all sub-scales. The factor-item and factor-factor correlations identified in these analyses were consistent with the conceptual framework of vulnerability of HIV infection in AGYW, suggesting good construct validity. The scale also demonstrated a statistically significant association with condomless sex and could be potentially used for sexual health risk stratification (OR = 1.17, 95% CI: 1.12, 1.23). The sexual health and HIV risk stratification scale demonstrated potential in identifying sexually active AGYW at high risk for HIV and other STIs. Ultimately, all AGYW in Tanzania are not at equal risk for HIV and this scale may support directing resources towards those at highest risk of HIV.

RESUMO

BACKGROUND: After several visits with unrelated complaints, a 16-year-old female patient disclosed symptoms of unwanted genital arousal and was diagnosed with persistent genital arousal disorder (PGAD). CASE: A 16-year-old female patient with history of depression, sexual abuse, and dysmenorrhea insistently requested etonogestrel rod removal. At 2 visits after implant removal, the patient disclosed the reason for her insistence: PGAD symptoms developed after implant insertion, although they worsened with removal. Chart review revealed selective serotonin reuptake inhibitor discontinuation before symptom onset. Normalization of sexual arousal occurred with counseling, selective serotonin reuptake inhibitor treatment, and hormonal contraception. SUMMARY AND CONCLUSION: This case highlights the importance of clinician recognition of PGAD symptoms, which adolescents might not openly disclose. Clinicians must nonjudgmentally collect medication history and sexual history, including sexual arousal and satisfaction, to make this diagnosis.
