Gendered dimensions of population mobility associated with HIV across three epidemics in rural Eastern Africa.

Mobility in sub-Saharan Africa links geographically-separate HIV epidemics, intensifies transmission by enabling higher-risk sexual behavior, and disrupts care. This population-based observational cohort study measured complex dimensions of mobility in rural Uganda and Kenya. Survey data were collected every 6 months beginning in 2016 from a random sample of 2308 adults in 12 communities across three regions, stratified by intervention arm, baseline residential stability and HIV status.

Development of a Novel Scale to Measure Male Partner Involvement in the Prevention of Mother-to-Child Transmission of HIV in Kenya.

Male partner involvement is an important factor in prevention of mother-to-child transmission (PMTCT). Yet, poor conceptualization has hindered optimal assessment of male involvement. We created and evaluated a brief 10-item male partner involvement scale using principal components analysis and scree plots, Cronbach's alpha, and linear regression with survey data from postpartum women with HIV (n = 200) in Kenya.

Tenofovir-Diphosphate as a Marker of HIV Pre-exposure Prophylaxis Use Among East African Men and Women.

Controlled pharmacokinetic (PK) studies in United States populations have defined categories of tenofovir-diphosphate (TFV-DP) in dried blood spots (DBS) for various pre-exposure prophylaxis (PrEP) adherence targets. It is unknown how these categories perform in other populations. Therefore, we evaluated the sensitivity and specificity of these PK-derived categories compared to daily medication electronic adherence monitoring (MEMS) data among East African men and women using daily PrEP.

Cellular immune responses against natural human papillomavirus infections among men in Kisumu, Kenya.

Human papillomavirus (HPV) is associated with ano-genital and cervical cancer. Persistence of oncogenic HPV genotypes is a requirement for development and progression of malignancies. Although, >70% of women clear incident HPV infections, data on natural history and HPV immunology among men is limited.

HIV prevalence, spatial distribution and risk factors for HIV infection in the Kenyan fishing communities of Lake Victoria.

Introduction: Global efforts to end HIV by 2030 focus on reducing and eventually eliminating new infections in priority populations. Identifying these populations and characterizing their vulnerability factors helps in guiding investment of scarce HIV prevention resources to achieve maximum impact. We sought to establish HIV prevalence, spatial distribution and risk factors for HIV infection in the Kenyan fishing communities of Lake Victoria.

Training health care providers to provide PrEP for HIV serodiscordant couples attending public health facilities in Kenya.

To catalyse national scale up of PrEP for HIV serodiscordant couples in public health facilities in Kenya, the Partners Scale-Up Project, using a two-day case-based interactive curriculum, trained health care providers working in 24 high volume facilities in central and western Kenya on PrEP service delivery. Using a standardised test with questions about PrEP and antiretroviral-based HIV prevention we assessed gain in knowledge and confidence gain by comparing pre-and post-training test scores. We explored experiences of the training through key informant interviews after clinics started delivering PrEP.

Empowering HIV-infected women in low-resource settings: A pilot study evaluating a patient-centered HIV prevention strategy for reproduction in Kisumu, Kenya.

Background: Female positive/male negative HIV-serodiscordant couples express a desire for children and may engage in condomless sex to become pregnant. Current guidelines recommend antiretroviral treatment in HIV-serodiscordant couples, yet HIV RNA viral suppression may not be routinely assessed or guaranteed and pre-exposure prophylaxis may not be readily available. Therefore, options for becoming pregnant while limiting HIV transmission should be offered and accessible to HIV-affected couples desiring children.

A Patient-Centered Multicomponent Strategy for Accelerated Linkage to Care Following Community-Wide HIV Testing in Rural Uganda and Kenya.

Introduction: As countries move toward universal HIV treatment, many individuals fail to link to care after diagnosis of HIV. Efficient and effective linkage strategies are needed.

Methods: We implemented a patient-centered, multicomponent linkage strategy in the SEARCH "test-and-treat" trial (NCT 01864603) in Kenya and Uganda.

PrEP as a Lifestyle and Investment for Adolescent Girls and Young Women in Sub-Saharan Africa.

Adolescent girls and young women (AGYW) are highly affected by the HIV epidemic, yet standard approaches to pre-exposure prophylaxis (PrEP) delivery will not meet their needs. This commentary highlights key characteristics of AGYW related to PrEP use and delivery, including typical neurocognitive development, lack of experience with sustained medication use, and the social and connected nature of AGYW's lives. We then suggest ways for programs to embrace these characteristics, such as presenting PrEP as a lifestyle choice and not a biomedical tool, making access to PrEP simple and easy, and recognizing the many influences AGYW face in taking PrEP.

The role of women's empowerment and male engagement in pregnancy healthcare seeking behaviors in western Kenya.

We sought to understand whether women's empowerment and male partner engagement were associated with use of antenatal care (ANC). Women presenting for ANC in Nyanza province of Kenya between June 2015 and May 2016, were approached for participation. A total of 137 pregnant women and 96 male partners completed baseline assessments.

Evaluation of a social network intervention on child feeding practices and caregiver knowledge.

Food insecurity and poor infant and young child feeding (IYCF) practices contribute to undernutrition. The Kanyakla Nutrition Program was developed in rural Kenya to provide knowledge alongside social support for recommended IYCF practices. Utilizing a social network approach, the Kanyakla Nutrition Program trained community health workers (CHWs) to engage mothers, fathers, and grandparents in nutrition education and discussions about strategies to provide instrumental, emotional, and information support within their community.

The HIV care continuum among resident and non-resident populations found in venues in East Africa cross-border areas.

Introduction: HIV care and treatment in cross-border areas in East Africa face challenges perhaps not seen to the same extent in other geographic areas, particularly for mobile and migrant populations. Here, we estimate the proportion of people with HIV found in these cross-border areas in each stage of the HIV care and treatment cascade, including the proportion who knows their status, the proportion on treatment and the proportion virally suppressed.

Methods: Participants (n = 11,410) working or socializing in public places in selected East Africa cross border areas were recruited between June 2016 and February 2017 using the Priorities for Local AIDS Control Efforts method and administered a behavioural survey and rapid HIV test.

Factors predictive of successful retention in care among HIV-infected men in a universal test-and-treat setting in Uganda and Kenya: A mixed methods analysis.

Background: Previous research indicates clinical outcomes among HIV-infected men in sub-Saharan Africa are sub-optimal. The SEARCH test and treat trial (NCT01864603) intervention included antiretroviral care delivery designed to address known barriers to HIV-care among men by decreasing clinic visit frequency and providing flexible, patient-centered care with retention support. We sought to understand facilitators and barriers to retention in care in this universal treatment setting through quantitative and qualitative data analysis.

Participation in a clinical trial of a text messaging intervention is associated with increased infant HIV testing: A parallel-cohort randomized controlled trial.

Objective: Text messages significantly improve uptake of infant HIV testing in clinical trial contexts. Women who were excluded from a randomized trial in Kenya were followed to create a comparison between women who were enrolled and did not receive the study SMS intervention and women who were screened but not enrolled.

Design: Parallel-cohort randomized controlled trial analysis.

Strengthening Mentoring in Low- and Middle-Income Countries to Advance Global Health Research: An Overview.

Mentoring is a proven path to scientific progress, but it is not a common practice in low- and middle-income countries (LMICs). Existing mentoring approaches and guidelines are geared toward high-income country settings, without considering in detail the differences in resources, culture, and structure of research systems of LMICs. To address this gap, we conducted five Mentoring-the-Mentor workshops in Africa, South America, and Asia, which aimed at strengthening the capacity for evidence-based, LMIC-specific institutional mentoring programs globally.

Mentorship and Ethics in Global Health: Fostering Scientific Integrity and Responsible Conduct of Research.

Addressing ethical issues through mentorship is key to encouraging scientific integrity and increasing research capacity. Across the global health arena, mentorship requires helping mentees understand and negotiate the regulatory aspects of research-which can substantially differ even between countries with similar resources. Mentorship support spans across the research framework from obtaining ethical approval and ensuring scientific integrity, to determining authorship and disseminating study results-providing multiple opportunities to model ethical behavior for mentees.

The Evolution of Mentorship Capacity Development in Low- and Middle-Income Countries: Case Studies from Peru, Kenya, India, and Mozambique.

Following the Fogarty International Center-supported "Mentoring the Mentors" workshops in South America, Africa, and Asia, approaches and guidelines for mentorship at institutions within these low- and middle-income country (LMIC) contexts, appropriate for the respective regional resources and culture, were implemented. Through the presentation of case studies from these three geographic regions, this article illustrates the institutional mentorship infrastructure before the workshop and the identified gaps used to implement strategies to build mentorship capacity at the Universidad Peruana Cayetano Heredia (Peru), Kenya Medical Research Institute (Kenya), Saint John's Research Institute (India), and Eduardo Mondlane University (Mozambique). These case studies illustrate three findings: first, that mentorship programs in LMICs have made uneven progress, and institutions with existing programs have exhibited greater advancement to their mentoring capacity than institutions without formal programs before the workshops.

Mentoring the Mentors: Implementation and Evaluation of Four Fogarty-Sponsored Mentoring Training Workshops in Low-and Middle-Income Countries.

A growing body of evidence highlights the importance of competent mentoring in academic research. We describe the development, implementation, and evaluation of four regional 2-day intensive workshops to train mid- and senior-level investigators conducting public health, clinical, and basic science research across multiple academic institutions in low- and middle-income countries (LMICs) on tools and techniques of effective mentoring. Sponsored by the Fogarty International Center, workshops included didactic presentations, interactive discussions, and small-group problem-based learning and were conducted in Lima, Peru; Mombasa, Kenya; Bangalore, India; and Johannesburg, South Africa, from 2013 to 2016.

Adoption of routine virologic testing and predictors of virologic failure among HIV-infected children on antiretroviral treatment in western Kenya.

Background: Access to routine virologic monitoring, critical to ensuring treatment success, remains limited in low- and middle-income countries. We report on implementation of routine viral load (VL) monitoring and risk factors for virologic failure among HIV-infected children on antiretroviral treatment (ART) in Western Kenya.

Methods: Routine VL testing was introduced in western Kenya in November 2013.

A Qualitative Exploration of Women's Experiences with a Community Health Volunteer-Led Cervical Cancer Educational Module in Migori County, Kenya.

Detection and treatment of human papillomavirus (HPV) and cervical precancer through screening programs is an effective way to reduce cervical cancer deaths. However, high cervical cancer mortality persists in low- and middle-income countries. As screening programs become more widely available, it is essential to understand how knowledge about cervical cancer and perceived disease risk impacts screening uptake and acceptability.

Marginalization and Community Perception of HIV Care, Treatment, and Support on Mfangano Island, Kenya.

Background: In rural sub-Saharan Africa (SSA), the human immunodeficiency virus (HIV)/AIDS pandemic has exerted effects on nearly every aspect of life. Yet despite the pandemic's near ubiquitous impacts, major barriers to HIV care, treatment, and support persist. Compounding the barriers to care is the incredible complexity and diversity of experience across different sociocultural contexts.

Retention and viral suppression of newly diagnosed and known HIV positive pregnant women on Option B+ in Western Kenya.

Kenya introduced universal antiretroviral treatment (ART) for pregnant and breastfeeding women living with HIV (Option B+) in 2014. A retrospective study was conducted to review consecutive records for HIV positive pregnant women presenting for antenatal care (ANC) at five clinics in western Kenya. Known positive women (KP :HIV diagnosis prior to current pregnancy) were compared to newly positive (NP) women regarding virologic suppression and retention in care.

Mobile, Population-wide, Hybrid HIV Testing Strategy Increases Number of Children Tested in Rural Kenya and Uganda.

Efficient ways to identify children with HIV in the context of universal test-and-treat policies are needed. We evaluated a hybrid testing strategy combining mobile community and home-based HIV testing in 87,700 children across 32 rural communities in 2 East African countries. This approach resulted in 81% testing coverage of at-risk children and doubled the number of children diagnosed with HIV.

Scale up of PrEP integrated in public health HIV care clinics: a protocol for a stepped-wedge cluster-randomized rollout in Kenya.

Background: Antiretroviral therapy (ART) for HIV-infected persons and pre-exposure prophylaxis (PrEP) for uninfected persons are extraordinarily effective strategies for HIV prevention. In Africa, the region which shoulders the highest HIV burden, HIV care is principally delivered through public health HIV care clinics, offering an existing platform to incorporate PrEP delivery and maximize ART and PrEP synergies. However, successfully bringing this integrated approach to scale requires an implementation science evaluation in public health settings.
