Is there an optimal screening tool for identifying perinatal depression within clinical settings of sub-Saharan Africa?
Abstract: Depression is a leading cause of maternal morbidity and mortality worldwide and the most common complication of the perinatal period. Women in sub-Saharan Africa (SSA) are disproportionately impacted by perinatal depression. Maternal and child health (MCH) clinics are widely attended in SSA, offering a potential access point for depression screening. Yet, selection of optimal depression screening instruments for use within MCH clinics in SSA remains unclear. We synthesized evidence depicting relative strength of perinatal depression screening scales for use among African perinatal women within four evaluation domains: 1) diagnostic performance, 2) cultural adaptation, 3) feasibility and ease of implementation, 4) experience using the tool in SSA perinatal populations. The Edinburgh Postnatal Depression Scale (EPDS) and Patient Health Questionnaire-9 (PHQ-9) had the most evidence among peripartum women in SSA, and a balance of feasibility, diagnostic performance metrics, and cultural adaptations. Other depressive screening instruments developed for general populations show strengths for application in African perinatal populations in at least one evaluation domain. Building health services capacity to integrate depression screening within routine MCH visits is an important next step to address perinatal depression in SSA
Editorial: Improving the delivery of pre-exposure prophylaxis (PrEP) to eliminate vertical HIV transmission
HIV pre-exposure prophylaxis (PrEP) significantly reduces new HIV infections. Among pregnant and lactating cisgender women in high HIV prevalence settings PrEP offers dual benefits for maternal and infant HIV prevention and is increasingly integral to vertical transmission prevention programs. Many countries in East and Southern Africa with high HIV burden have integrated oral PrEP into HIV prevention programs, in the form of daily oral tenofovir disoproxil fumarate (TDF) containing regimens. While daily oral TDF-based PrEP use in pregnancy and lactation is considered safe and effective, only recently are data on PrEP implementation and extended safety emerging. As additional PrEP options become available, there is a need for more evidence on how to ensure effective antenatal and postnatal use
Association between male circumcision and incidence of syphilis in men and women: a prospective study in HIV-1 serodiscordant heterosexual African couples
Background Male circumcision is a primary HIV-1 prevention intervention for men, but whether the procedure
reduces the risk of syphilis among men and their female partners is uncertain. We aimed to assess whether male
circumcision was associated with incident syphilis in men and in their female partners.
Methods In this large prospective cohort study, participants were members of Kenyan and Ugandan HIV-1
serodiscordant heterosexual couples enrolled in a randomised safety and effi cacy clinical trial of pre-exposure
prophylaxis for HIV-1 prevention (the Partners PrEP Study). Participants attended monthly or quarterly follow-up
visits for up to 36 months. Annually, syphilis serology testing was done and male circumcision status was assessed.
We used multivariate Andersen-Gill survival methods, adjusted for age, sexual behaviour, and plasma HIV RNA
levels of the HIV-infected partner.
Findings 4716 HIV-1 serodiscordant couples (38%) with a man with HIV were followed for a median of 2·75 years. At
enrolment, 1575 (53%) men with HIV and 560 (32%) men without HIV were circumcised; an additional 69 (4%) men
with HIV and 132 (5%) men without HIV were circumcised during study follow-up. 221 incident syphilis infections
were reported: 46 (21%) in men with HIV (incidence 1·10 per 100 person-years), 76 (34%) in men without HIV (1·09),
54 (24%) in women with HIV (0·77), and 45 (24%) in women without HIV (1·11). Male circumcision was associated
with a 42% reduction in incident syphilis in men (adjusted hazard ratio [aHR] 0·58, 95% CI 0·37–0·91) including a
62% reduction in men with HIV (0·38, 0·18–0·81), and a non-signifi cant reduction in incident syphilis in men
without HIV (0·64, 0·36–1·11). In women, circumcision of their male partners was associated with a 59% reduction
in incident syphilis (aHR 0·41, 95% CI 0·25–0·69), including a 75% reduction in women without HIV (0·25,
0·08–0·76) and a 48% reduction in women with HIV (0·52, 0·27–0·97).
Interpretation Male circumcision was associated with decreased risk of incident syphilis in men and women. If
confi rmed, these results suggest that medical male circumcision could substantially reduce incidence of syphilis and its sequelae
Implementation determinants and strategies in integration of PrEP into maternal and child health and family planning services: experiences of frontline healthcare workers in Kenya
BackgroundDelivery of PrEP to adolescent girls and young women (AGYW) and to pregnant women through maternal and child health (MCH) and family planning (FP) clinics is scaling up in Kenya. Evaluation of implementation challenges and strategies is critical to optimize delivery.MethodsWe conducted focus group discussions (FGDs) with healthcare workers (HCWs) in MCH and FP clinics offering PrEP in a large implementation project in Kisumu, Kenya. Discussion guides were based on the Consolidated Framework for Implementation Research (CFIR). FGDs were audio recorded and transcribed. Directed content analysis was used to identify implementation challenges and strategies to overcome them.ResultsFifty HCWs from 26 facilities participated in 8 FGDs. HCWs believed PrEP integration was appropriate because it met the needs of AGYW and pregnant women by providing a female-controlled prevention strategy and aligned with policy priorities of elimination of vertical HIV transmission. They were universally accepting of PrEP provision, especially through MCH clinics, noting the relative advantage of this approach because it: (1) enabled high coverage, (2) harmonized PrEP and MCH visits, and (3) minimized stigma compared to PrEP offered through HIV care clinics. However, HCWs noted implementation challenges affecting feasibility and adoption including: (1) increased workload and documentation burden amid workforce shortages, (2) insufficient health care worker knowledge (3) multiple implementing partners with competing priorities (4) drug and documentation form stockouts. HCWs employed various implementation strategies to overcome challenges, including task shifting from nurses to HIV testing providers, patient flow modifications (e.g., fast-tracking PrEP clients to reduce wait times), PrEP demand generation and myth clarification during health talks, provider education, dedicated PrEP delivery rooms, and coordination with adolescent-friendly services. Additional suggested strategies to improve PrEP integration included community education to increase broader PrEP awareness and enable shorter counseling sessions, and task-shifting data entry and client risk assessments.ConclusionsHCWs were enthusiastic about the appropriateness and acceptability of integrating PrEP services into MCH and FP clinics but noted challenges to adoption and feasibility. Strategies to address challenges focused on improving provider time and space constraints, and increasing provider and client knowledge
Where are the pregnant and breastfeeding women in new pre-exposure prophylaxis trials? The imperative to overcome the evidence gap
Pregnant and breastfeeding populations are at substantial risk of acquiring HIV in some settings, yet are underrepresented in clinical trials of new pre-exposure prophylaxis (PrEP) agents. Several PrEP formulations are in development (eg, vaginal rings, long-acting injectables, and other modalities). Pregnant and breastfeeding populations are typically excluded from initial clinical trials. We identified 14 PrEP trials of novel agents in non-pregnant or non-breastfeeding populations, and six phase 1–3 trials and open label extensions among pregnant and breastfeeding populations, that are currently ongoing or complete. A framework shift is needed to consider the ethical costs of excluding pregnant and breastfeeding populations at risk for HIV in PrEP clinical trials and promote inclusion to maximise the benefits from PrEP tools in the pipeline. Research on new PrEP agents should include pregnant and breastfeeding populations to avoid delays in reaching those who could benefit from PrEP after efficacy is established.https://www.thelancet.com/journals/lanhiv/homehj2023Paediatrics and Child Healt
Understanding factors influencing home pregnancy test use among women in western Kenya: A qualitative analysis
BackgroundThere are limited data on home pregnancy test use among women in low-and-middle-income countries. A prior survey found that only 20% of women in western Kenya used a home pregnancy test to confirm their pregnancies before going to antenatal care. This qualitative study aims to understand why women do not use home pregnancy tests in early pregnancy.MethodsFrom April 2021 to July 2021, we interviewed women from four antenatal care clinics in Homa Bay and Siaya counties. We recruited women previously enrolled in the PrEP Implementation for Mothers in Antenatal care (PrIMA) study, a cluster-randomized trial that evaluated the best approaches to implementing PrEP in maternal and child health clinics in Western Kenya (NCT03070600). Interviews were conducted via phone, audio recorded, translated, and transcribed verbatim. We coded and analyzed the transcripts to capture factors influencing women's capability, opportunity, and motivation to use home pregnancy tests.ResultsWe conducted 48 semistructured interviews with women aged 21–42 years. Twenty-seven women did not use a home pregnancy test in their most recent pregnancy. Seventeen of these women reported not using a home pregnancy test before. Lack of knowledge, mistrust in the accuracy of tests, preferring to rely on signs and symptoms of pregnancy or get a test from the health facility, cost, and accessibility were key barriers to home pregnancy test use.ConclusionImproving the uptake of home pregnancy testing during early pregnancy will require efforts to enhance community knowledge of test use and associated benefits and reduce cost burdens by making tests more affordable and accessible

Delivery of Antiretroviral Pre-exposure Prophylaxis for HIV prevention in Pregnant and Postpartum Women
Thesis (Ph.D.)--University of Washington, 2017-06Women in sub-Saharan Africa have substantial risk of acquiring HIV acquisition during and soon after pregnancy. Additionally, acute HIV infection among pregnant and breastfeeding women poses a double burden in that acute maternal HIV accounts for nearly one-third of all mother-to-child transmissions of HIV (MTCT). To reach global targets for elimination of MTCT and HIV prevention for mothers, it is critical to integrate effective primary HIV prevention strategies into maternal and child health (MCH) services. Tenofovir disoproxil fumarate (TDF)-based pre-exposure prophylaxis (PrEP) prevents HIV infection in adherent women. The World Health Organization (WHO) recommends PrEP for all individuals, including pregnant and breastfeeding women, at substantial HIV risk (defined as HIV residence in regions where HIV incidence is >3%). Programmatic delivery of PrEP for pregnant women is currently being considered in high-prevalence regions, though implementation approaches that efficiently optimize the benefit of PrEP during pregnancy have not been defined. Additionally, although WHO guidelines support PrEP use in pregnancy, national committees have differed in their conclusions. For example, PrEP use during pregnancy is supported by Kenyan antiretroviral guidelines but the lack of complete safety data led PrEP to be contraindicated for pregnant women in the current South African PrEP guidelines. As countries expand programmatic delivery of PrEP to pregnant women, it is important to understand motivations and beliefs for using PrEP during pregnancy to address concerns unique to this population. The studies within this dissertation address the implementation science gaps described above for the delivery of PrEP for HIV prevention to pregnant and postpartum in sub-Saharan Africa. To inform efficient PrEP delivery models, we present an empiric risk score for identifying pregnant and postpartum Kenyan women at highest risk for HIV acquisition who would mostly benefit from PrEP while reducing unnecessary exposure among low-risk women. Using data that could be easily collected in standard MCH clinic settings without additional laboratory diagnostics, our risk score identified 56% of pregnant women who acquired HIV among just 16% of women. Using register data from 62 antenatal MCH facilities throughout Kenya, we further estimated the absolute number and proportion of HIV-uninfected pregnant women in Kenya who could be offered PrEP under different public health approaches, including offering PrEP universally or based on either regional HIV prevalence and/or individual-level HIV risk factors. We found that offering PrEP only to pregnant women in the region with highest HIV prevalence (Nyanza) would reduce PrEP use among low-risk women by 74%, but exclude 63% of women with high risk for HIV based on individual-level characteristics nationally. To complement service delivery data, we also assessed experiences of using PrEP during pregnancy among HIV-uninfected Kenyan women in HIV-serodiscordant couples who became pregnant while using PrEP. The personal experiences of women with direct exposure to PrEP during pregnancy offers valuable insights for informing development of effective PrEP messaging strategies and programs. Finally, we evaluate whether adverse perinatal outcomes were more frequent in a cohort of Kenyan and Ugandan HIV-infected women who used TDF-containing antiretroviral therapy (ART) during pregnancy compared to HIV-infected women who used ART during pregnancy that did not contain TDF. Our findings support the growing evidence that prolonged prenatal TDF use is not associated with adverse perinatal outcomes and contribute to the few prospective studies evaluating the safety of TDF use during pregnancy from African cohorts. The studies within this dissertation aim to address these implementation science gaps and inform optimal and effective delivery of PrEP for HIV prevention to pregnant and postpartum in sub-Saharan Africa
