Background: Increased risk of HIV acquisition during pregnancy and lactation among women is evident, necessitating their inclusion in the evaluation of new HIV prevention interventions. Pregnant and postpartum women specifically face challenges with oral PrEP associated with stigma, and the burden of using other tablets. Long-acting products may address challenges related to oral PrEP, however, there is limited data on product-specific preferences and acceptability among pregnant and lactating women.

Uganda started implementing mass drug administration against schistosomiasis in 2003, with district used as an implementation unit. This resulted into misclassification of communities into wrong risk levels, under-or-over treatment and over request of praziquantel (PZQ) drugs. The objective of the current study was to reviewing the community data available at World Health Organization/ESPEN database to understand the status of schistosomiasis and identify pockets with infection.

Exposure to pulmonary tuberculosis (PTB) culminates in heterogeneous outcomes, including variation in Mtb antigen-specific interferon-gamma (IFN-γ) T-cell responses. IFN-γ-independent cytokines, including tumor necrosis factor (TNF) and interleukin (IL-2), offer potential diagnostic improvements and insights into pathogenesis. We hypothesized that ESAT6/CFP10 TNF and IL-2 responses improve Mtb infection detection among exposed household contacts (HHCs) and are associated with index case Mtb aerosolization (i.

Objective measures of oral PrEP adherence - especially point-of-care (POC) measures that enable real-time assessment, intervention, and feedback - have the potential to improve adherence. Our team previously developed and validated a novel urine-based POC metric of PrEP adherence. In this study, we sought to determine whether this assay is acceptable and feasible among women taking PrEP and PrEP providers in Kenya.

Background: Despite the recognised links between food insecurity and parenting, few studies have evaluated the perceived impacts of livelihood or food security interventions on parental practices, intra-household functioning, adolescent behaviour and psychosocial outcomes in HIV-affected households in sub-Saharan Africa.
Aims: The study aimed to understand the perceived effects of food security on parenting practices and how this was experienced by both adolescent girls (aged 13-19 years) and their caregivers in rural Kenya.
Method: We conducted semi-structured, individual interviews with 62 caregiver-adolescent dyads who were participants in the adolescent (NCT03741634), a sub-study of adolescent girls and caregivers with a household member participating in the agricultural and finance intervention trial (NCT01548599).
Background: New vaccines for pregnant women have recently been introduced in some high-income countries to protect infants in early life. Implementing maternal immunisation (MI) successfully in low- and middle-income countries will require planning and adaptations to immunisation and maternal health programs. To inform cost of MI delivery studies, we gathered perspectives from key stakeholders in five countries (Bangladesh, Ghana, Kenya, Mozambique, and Nepal) regarding health system requirements, opportunities, and challenges to introducing new maternal vaccines into routine health programs.

Background: CD4+ T cells expressing α4β7 are optimal targets for HIV infections, with higher pre-HIV α4β7hi expression linked to increased HIV acquisition and progression in South African women. However, similar associations were not observed in men who have sex with men (MSM) or people who inject drugs (PWID) in the Americas, indicating need for further research.
Methods: This retrospective case-control study enrolled heterosexual men and women from South Africa (HIV Vaccine Trials Network; HVTN 503) and East Africa (Partners Pre-Exposure Prophylaxis/Couples' Observational Study; PP/COS), quantifying α4β7 expression on CD4+ T cells as a predictor of subsequent HIV risk using flow cytometry analyses.
Tsetse flies and trypanosomosis significantly impact bovine production and human health in sub-Saharan Africa, exacerbating underdevelopment, malnutrition, and poverty. Despite various control strategies, long-term success has been limited. This study evaluates the combined use of entomopathogenic fungi (EPF) and the sterile insect technique (SIT) to combat tsetse flies.

Background: Spatial repellent products are used for prevention of insect bites, and a body of evidence exists on spatial repellent entomological efficacy. A new option for vector control, spatial repellent products are designed to release active ingredient into the air for disruption of human-vector contact thereby reducing human exposure to mosquito-borne pathogens. Clinical trials have shown spatial repellent epidemiological efficacy against Aedes-borne viruses but inconclusive outcomes against malaria.

Accurate detection of schistosome infections in snails is vital for epidemiologic and laboratory studies. Traditional microscopy methods to detect schistosomes in snails are hindered by long prepatent periods and snail survivorship, leading to inaccurate assessment of infections. A rapid, multiplexed PCR assay targeting Biomphalaria sudanica or Biomphalaria glabrata (internal control) and Schistosoma mansoni DNA is described.

Adolescent girls and young women (AGYW) seeking post-abortal care (PAC) remain at risk of unintended pregnancies and HIV due to infrequent condom use. Integrating HIV prevention services, such as PrEP, into PAC services offers an opportunity to enhance reach, uptake, and efficiency, particularly in high-burden settings like Kenya. However, data on acceptability, feasibility, and sustainability of PAC clinics as entry points for PrEP is limited.

Praziquantel alone is insufficient for the control of schistosomiasis due to poor efficacy against juvenile worms and increasing concerns about the risk of drug resistance. We compared the efficacy and safety of praziquantel combined with four different artemisinin-based combinations to praziquantel alone in treating infection in Kenyan children. In this randomized, open-label, five-arm, head-to-head, non-inferiority trial, children (aged 9-15 years) with infection according to duplicate Kato Katz thick smears from a stool sample in the Mwea irrigation scheme of central Kenya, were enrolled.

Sexual and/or injecting partners of people who inject drugs (PWID) may have an elevated risk of HIV infection either from sharing a transmission network or an epidemiological environment. We estimated the degree of similarity between HIV and hepatitis C (HCV) sequences from PWID and their partners to assess whether partner-based recruitment identifies sexual or injecting partners within transmission networks. We used assisted partner services (APS) to recruit sexual and injecting partners of PWID living with HIV in Kenya and evaluated trends in the TN93 distances (an adjusted measure of sequence similarity) of the HIV-1 and HCV sequences from partner pairs.
