Evaluating the effectiveness of a multi-component intervention on early childhood development in paediatric HIV care and treatment programmes: a randomised controlled trial.

Background: HIV infection in a family may affect optimum child development. Our hypothesis is that child development outcomes among HIV-exposed infants will be improved through a complex early childhood stimulation (ECS) programme, and income and loans saving programme for HIV positive parents.

Methods: The study was a cluster-randomized controlled trial in 30 clinic sites in two districts in Zimbabwe.

Sexual health interventions for young people in state care: a systematic review.

Objectives: To describe evaluated sexual health interventions for young people in state care and provide an assessment of the quality of and evidence for these interventions.

Methods: A systematic review of sexual health interventions for young people in state care was conducted. Randomised controlled trials and quasi-experimental designs were eligible, 2051 records were screened, 412 full-text studies retrieved, and 12 publications with low-to-moderate risk of bias included.

"Well, not me, but other women do not register because..."- Barriers to seeking antenatal care in the context of prevention of mother-to-child transmission of HIV among Zimbabwean women: a mixed-methods study.

Background: While barriers to uptake of antenatal care (ANC) among pregnant women have been explored, much less is known about how integrating prevention of mother-to-child transmission (PMTCT) programmes within ANC services affects uptake. We explored barriers to uptake of integrated ANC services in a poor Zimbabwean community.

Methods: A cross-sectional survey was conducted among post-natal women at Mbare Clinic, Harare, between September 2010 and February 2011.

Reflections on the Use of Audio Diaries to Access Young People's Lived Experiences of HIV in Zimbabwe.

This methodological article reflects on the contribution audio diaries can make to accessing important, and commonly silenced, dimensions of the lived experience of growing up with HIV and their acceptability to children. Audio diaries were used by 12 young people, aged 11 to 13 years, as part of a longitudinal qualitative study embedded within the Anti-Retroviral Research for Watoto (ARROW) clinical trial. The method provided an alternative means for young people to express detailed reflections on their day-to-day encounters, as well as ordinarily silenced topics, including hidden and suppressed emotions regarding the circumstance surrounding their perinatal infection.

Preferences for linkage to HIV care services following a reactive self-test: discrete choice experiments in Malawi and Zambia.

Objectives: The current research identifies key drivers of demand for linkage into care following a reactive HIV self-test result in Malawi and Zambia. Preferences are explored among the general population and key groups such as HIV-positive individuals and adolescents.

Design: We used discrete choice experiments (DCEs) embedded in representative household surveys to quantify the relative strength of preferences for various HIV services characteristics.

Postpartum maternal mental health is associated with cognitive development of HIV-exposed infants in Zimbabwe: a cross-sectional study.

This study examines the cognitive profiles of infants born to HIV positive mothers in Zimbabwe. Caregivers with HIV exposed infants delivered in 30 clinics in two areas of Zimbabwe were recruited to the study. Of the 574 study participants, 562 caregiver-infant dyads with a biological HIV +ve mother and infant aged 0-24 months were interviewed.

Impact of Counseling Received by Adolescents Undergoing Voluntary Medical Male Circumcision on Knowledge and Sexual Intentions.

Background: Little is known regarding the impact of counseling delivered during voluntary medical male circumcision (VMMC) services on adolescents' human immunodeficiency virus (HIV) knowledge, VMMC knowledge, or post-VMMC preventive sexual intentions. This study assessed the effect of counseling on knowledge and intentions.

Methods: Surveys were conducted with 1293 adolescent clients in 3 countries (South Africa, n = 299; Tanzania, n = 498; Zimbabwe, n = 496).

Perceived Quality of In-Service Communication and Counseling Among Adolescents Undergoing Voluntary Medical Male Circumcision.

Background: Experience with providers shapes the quality of adolescent health services, including voluntary medical male circumcision (VMMC). This study examined the perceived quality of in-service communication and counseling during adolescent VMMC services.

Methods: A postprocedure quantitative survey measuring overall satisfaction, comfort, perceived quality of in-service communication and counseling, and perceived quality of facility-level factors was administered across 14 VMMC sites in South Africa, Tanzania, and Zimbabwe.

Parental Communication, Engagement, and Support During the Adolescent Voluntary Medical Male Circumcision Experience.

Background: Voluntary medical male circumcision (VMMC) is one of few opportunities in sub-Saharan Africa to engage male adolescents in the healthcare system. Limited data are available on the level of parental communication, engagement, and support adolescents receive during the VMMC experience.

Methods: We conducted 24 focus group discussions with parents/guardians of adolescents (N = 192) who agreed to be circumcised or were recently circumcised in South Africa, Tanzania, and Zimbabwe.

Adolescent Wound-Care Self-Efficacy and Practices After Voluntary Medical Male Circumcision-A Multicountry Assessment.

Background: Adolescent boys (aged 10-19 years) constitute the majority of voluntary medical male circumcision (VMMC) clients in sub-Saharan Africa. They are at higher risk of postoperative infections compared to adults. We explored adolescents' wound-care knowledge, self-efficacy, and practices after VMMC to inform strategies for reducing the risks of infectious complications postoperatively.

Counseling Received by Adolescents Undergoing Voluntary Medical Male Circumcision: Moving Toward Age-Equitable Comprehensive Human Immunodeficiency Virus Prevention Measures.

Background: The minimum package of voluntary medical male circumcision (VMMC) services, as defined by the World Health Organization, includes human immunodeficiency virus (HIV) testing, HIV prevention counseling, screening/treatment for sexually transmitted infections, condom promotion, and the VMMC procedure. The current study aimed to assess whether adolescents received these key elements.

Methods: Quantitative surveys were conducted among male adolescents aged 10-19 years (n = 1293) seeking VMMC in South Africa, Tanzania, and Zimbabwe.

Age Differences in Perceptions of and Motivations for Voluntary Medical Male Circumcision Among Adolescents in South Africa, Tanzania, and Zimbabwe.

Background: The World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) have set a Fast-Track goal to achieve 90% coverage of voluntary medical male circumcision (VMMC) among boys and men aged 10-29 years in priority settings by 2021. We aimed to identify age-specific facilitators of VMMC uptake among adolescents.

Methods: Younger (aged 10-14 years; n = 967) and older (aged 15-19 years; n = 559) male adolescents completed structured interviews about perceptions of and motivations for VMMC before receiving VMMC counseling at 14 service provision sites across South Africa, Tanzania, and Zimbabwe.

Females' Peer Influence and Support for Adolescent Males Receiving Voluntary Medical Male Circumcision Services.

Background: While female involvement in voluntary medical male circumcision (VMMC) has been studied among adults, little is known about the influence of adolescent females on their male counterparts. This study explored adolescent females' involvement in VMMC decision making and the postoperative wound healing process in South Africa, Tanzania, and Zimbabwe.

Methods: Across 3 countries, 12 focus group discussions were conducted with a total of 90 adolescent females (aged 16-19 years).

Providers' Perceptions and Training Needs for Counseling Adolescents Undergoing Voluntary Medical Male Circumcision.

Background: The majority of individuals who seek voluntary medical male circumcision (VMMC) services in sub-Saharan Africa are adolescents (ages 10-19 years). However, adolescents who obtain VMMC services report receiving little information on human immunodeficiency virus (HIV) prevention and care. In this study, we assessed the perceptions of VMMC facility managers and providers about current training content and their perspectives on age-appropriate adolescent counseling.

Adaptive Reconfiguration of Natural Killer Cells in HIV-1 Infection.

Human cytomegalovirus (HCMV) co-infection is highly prevalent within HIV-1 cohorts and is an important cofactor in driving ongoing immune activation, even during effective antiretroviral treatment. HCMV infection has recently been associated with expansion of adaptive-like natural killer (NK) cells, which harbor epigenetic alterations that impact on their cellular function and phenotype. The influence of HCMV co-infection on the considerable heterogeneity among NK cells and their functional responses to different stimuli was assessed in a cohort of HIV-1-infected individuals sampled during different stages of infection, compared with healthy subjects stratified according to HCMV serostatus.

Antiretroviral Therapy and Mortality in Rural South Africa: A Comparison of Causal Modeling Approaches.

Estimation of causal effects from observational data is a primary goal of epidemiology. The use of multiple methods with different assumptions relating to exchangeability improves causal inference by demonstrating robustness across assumptions. We estimated the effect of antiretroviral therapy (ART) on mortality in rural KwaZulu-Natal, South Africa, from 2007 to 2011, using 2 methods with substantially different assumptions: the regression discontinuity design (RDD) and inverse-probability-weighted (IPW) marginal structural models (MSMs).

Reaching young women who sell sex: Methods and results of social mapping to describe and identify young women for DREAMS impact evaluation in Zimbabwe.

Young women (aged 15-24) who exchange sex for money or other support are among the highest risk groups for HIV acquisition, particularly in high prevalence settings. To prepare for introduction and evaluation of the DREAMS programme in Zimbabwe, which provides biomedical and social interventions to reduce adolescent girls' and young women's HIV vulnerability, we conducted a rapid needs assessment in 6 towns using a "social mapping" approach. In each site, we talked to adult sex workers and other key informants to identify locations where young women sell sex, followed by direct observation, group discussions and interviews.

Cross-sectional study of CD4: CD8 ratio recovery in young adults with perinatally acquired HIV-1 infection.

Antiretroviral therapy (ART) has improved survival into adulthood for young people with perinatally acquired HIV-1 (yp-PaHIV), but long-term prognosis remains unclear. We hypothesized that on-going immune activation, reflected in the failure of CD4:CD8 ratio normalization would be observed in yp-PaHIV, despite ART.A cross-sectional study of routinely collected clinical data from a cohort of yp-PaHIV (≥16 years).

Prevalence of and factors associated with MDR Neisseria gonorrhoeae in England and Wales between 2004 and 2015: analysis of annual cross-sectional surveillance surveys.

Objectives: To describe trends in prevalence, susceptibility profile and risk factors for MDR Neisseria gonorrhoeae (MDR-NG) in England and Wales.

Methods: Isolates from 16 242 gonorrhoea episodes at sexual health clinics within the Gonococcal Resistance to Antimicrobials Surveillance Programme (GRASP) underwent antimicrobial susceptibility testing. MDR-NG was defined as resistance to ceftriaxone, cefixime or azithromycin, plus at least two of penicillin, ciprofloxacin and spectinomycin.

Evaluating the impact of DREAMS on HIV incidence among young women who sell sex: protocol for a non-randomised study in Zimbabwe.

Background: "Determined, Resilient, AIDS-free, Mentored and Safe" (DREAMS) is a package of biomedical, social and economic interventions offered to adolescent girls and young women aged 10-24 years with the aim of reducing HIV incidence. In four of the six DREAMS districts in Zimbabwe, DREAMS includes an offer of oral pre-exposure prophylaxis (DREAMS+PrEP), alongside interventions to support demand and adherence, to women aged 18-24 who are at highest risk of HIV infection, including young women who sell sex (YWSS). This evaluation study addresses the question: does the delivery of DREAMS+PrEP through various providers reduce HIV incidence among YWSS Zimbabwe? We describe our approach to designing a rigorous study to assess whether DREAMS+PrEP had an impact on HIV incidence.

Impact of early antiretroviral therapy eligibility on HIV acquisition: household-level evidence from rural South Africa.

Objectives: We investigate the effect of immediate antiretroviral therapy (ART) eligibility on HIV incidence among HIV-uninfected household members.

Design: Regression discontinuity study arising from a population-based cohort.

Methods: Household members of patients seeking care at the Hlabisa HIV Treatment and Care Programme in rural KwaZulu-Natal South Africa between January 2007 and August 2011 with CD4 cell counts up to 350 cells/μl were eligible for inclusion if they had at least two HIV tests and were HIV-uninfected at the time the index patient linked to care (N = 4115).

Understanding the experience and manifestation of depression in adolescents living with HIV in Harare, Zimbabwe.

Background: Studies have found that adolescents living with HIV are at risk of depression, which in turn affects adherence to medication. This study explored the experience and manifestation of depression in adolescents living with HIV in Zimbabwe in order to inform intervention development.

Methods: We conducted a body mapping exercise with 21 HIV positive 15-19 years olds who had been diagnosed with major depressive disorder.

Mortality and causes of death in people diagnosed with HIV in the era of highly active antiretroviral therapy compared with the general population: an analysis of a national observational cohort.

Background: Deaths in HIV-positive people have decreased since the introduction of highly active antiretroviral therapy (HAART) in 1996. Fewer AIDS-related deaths and an ageing cohort have resulted in an increase in the proportion of HIV patients dying from non-AIDS-related disorders. Here we describe mortality and causes of death in people diagnosed with HIV in the HAART era compared with the general population.

Effectiveness and cost-effectiveness of implementing HIV testing in primary care in East London: protocol for an interrupted time series analysis.

Introduction: HIV remains underdiagnosed. Guidelines recommend routine HIV testing in primary care, but evidence on implementing testing is lacking. In a previous study, the Rapid HIV Assessment 2 (RHIVA2) cluster randomised controlled trial, we showed that providing training and rapid point-of-care HIV testing at general practice registration (RHIVA2 intervention) in Hackney led to cost-effective, increased and earlier diagnosis of HIV.
