Background: The Fogarty International Center-led Adolescent HIV Implementation Science Alliance (AHISA) supports region-/country-specific implementation science (IS) alliances that build collaborations between research, policy, and program partners that respond to local implementation challenges. AHISA supported the development of seven locally-led IS alliances: five countryspecific (i.e., Kenya, South Africa, Tanzania, Uganda, and Zambia), one in Central and West Africa, and one with youth researchers. This article outlines the aims, activities, and outcomes of local alliances, demonstrating how they enhance sustainable IS activities to address local challenges. Methods: We conducted a desk review of each alliance's funding applications, reports, and data from the initial findings of a larger AHISA evaluation. The review analyzes common approaches, highlights their local relevance, and summarizes initial outcomes. Results: The local alliances have a common goal: to expand implementation of successful interventions to improve adolescent HIV. We identified four overarching themes across the local alliances' activities: capacity building, priority setting, stakeholder engagement, and knowledge dissemination. Research capacity building activities include long-term mentorship between junior and senior researchers and short-term training for non-research partners. Setting priorities with members identifies local research needs and streamlines activities. Alliances incorporate substantial engagement between partners, particularly youth, who may serve as leaders and co-create activities. Dissemination shares activities and results broadly. Conclusion: Local IS alliances play a key role in building sustainable IS learning and collaboration platforms, enabling improved uptake of evidence into policy and programs, increased IS research capacity, and shared approaches to addressing implementation challenges.

Objectives: This study investigates the prevalence of the use of reusable menstrual materials in LMICs, examines differences in prevalence between countries and areas, and identifies individual and country-level factors associated with their use. Methods: Data from Multiple Indicator Cluster surveys conducted between 2017 and 2020 in LMICs were used. Prevalence estimates and 95% CIs were calculated for overall, rural, and urban areas. Multivariable logistic regression was used to identify individual and country-level factors associated with the use of reusable menstrual materials. Results: The study included 42 surveys from LMICs, with 1653850 weighted women and girls aged 15–49 years. The overall prevalence of the use of reusable menstrual materials was 12.1% (95% CI 12.1–12.2), with significant variation between and within countries, ranging from 0.5% (0.3–0.8) in Serbia to 97.2% (96.5–97.9) in Sao Tome and Principe. The prevalence was higher in rural areas (23.9% [23.8–24.0]) than in urban areas (6.2% [6.2–6.2]), with significant differences between most countries. Use of reusable menstrual materials was associated with lower education levels, being married, low economic status, living in Asia and Africa, living in countries with lower GDP, living in rural areas, and limited availability of private places to wash menstrual materials. The prevalence of the use of reusable menstrual materials had an inverse linear relationship with the country's GDP. Conclusions: The study found that the use of reusable menstrual materials is more prevalent among women and girls in rural areas, those with lower education levels, lower economic status, and those living in countries with lower GDP. Given these disparities, policies and initiatives targeted at improving menstrual health in LMICs should focus on socioeconomically disadvantaged groups to ensure they have access to safe and appropriate menstrual materials.

We examined the association between serum aflatoxin B1‐lysine adduct (AFB1‐lys) levels in pregnant women and adverse pregnancy outcomes (low birthweight, miscarriage and stillbirth) through a nested matched case–control study of pregnant women enroled at ≤28 weeks' gestation in Mombasa, Kenya, from 2017 to 2019. Cases comprised women with an adverse birth outcome, defined as either delivery of a singleton infant weighing <2500 g, or a miscarriage, or a stillbirth, while controls were women who delivered a singleton live infant with a birthweight of ≥2500 g. Cases were matched to controls at a ratio of 1:2 based on maternal age at enrolment, gestational age at enrolment and study site. The primary exposure was serum AFB1‐lys. The study included 125 cases and 250 controls. The median gestation age when serum samples were collected was 23.0 weeks (interquartile range [IQR]: 18.1–26.0) and 23.5 (IQR: 18.1–26.5) among cases and controls, respectively. Of the 375 tested sera, 145 (38.7%) had detectable serum AFB1‐lys: 36.0% in cases and 40.0% in controls. AFB1‐lys adduct levels were not associated with adverse birth outcomes on multivariable analysis. Mid‐upper arm circumference was associated with a 6% lower odds of adverse birth outcome for every unit increase (p = 0.023). Two‐fifths of pregnant women had detectable levels of aflatoxin midway through pregnancy. However, we did not detect an association with adverse pregnancy outcomes, likely because of low serum AFB1‐lys levels and low power, restricting meaningful comparison. More research is needed to understand the public health risk of aflatoxin in pregnant women to unborn children. Key messages: Aflatoxin B1 (AFB1), a commonly ingested toxin, can cross the placental barrier and cause adverse pregnancy outcomes.Two‐fifths of participants had detectable serum AFB1‐lys levels, a marker of aflatoxin exposure, but the low levels recorded were not associated with adverse pregnancy outcomes.Every unit increase in mid‐upper arm circumference (MUAC) during pregnancy was associated with a 6% reduced likelihood of adverse pregnancy outcomes, highlighting the potential protective role of adequate maternal nutrition.There is need for additional studies in different settings on the determinants and mechanisms of the relationship between aflatoxin exposure and adverse pregnancy outcomes.

Introduction: Adverse birth outcomes particularly preterm births and congenital anomalies, are the leading causes of infant mortality globally, and the burden is highest in developing countries. We set out to determine the frequency of adverse birth outcomes and the risk factors associated with such outcomes in a cohort of pregnant women in Kenya. Methods: From October 2017 to July 2019, pregnant women < 28 weeks gestation were enrolled and followed up until delivery in three hospitals in coastal Kenya. Newborns were examined at delivery. Among women with birth outcome data, we assessed the frequency of congenital anomalies defined as gastroschisis, umbilical hernia, limb abnormalities and Trisomy 21, and adverse birth outcomes, defined as either stillbirth, miscarriage, preterm birth, small for gestational age, or microcephaly. We used log-binomial regression to identify maternal characteristics associated with the presence of at least one adverse outcome. Results: Among the 2312 women enrolled, 1916 (82.9%) had birth outcome data. Overall, 402/1916 (20.9%; 95% confidence interval (CI): 19.1–22.8) pregnancies had adverse birth outcomes. Specifically, 66/1916 (3.4%; 95% CI: 2.7–4.4) were stillbirths, 34/1916 (1.8%; 95% CI: 1.2–2.4) were miscarriages and 23/1816 (1.2%; 95% CI: 0.8–1.9) had congenital anomalies. Among the participants with anthropometric measurements data, 142/1200 (11.8%; 95% CI: 10.1 − 13.8) were small for gestational age and among the participants with ultrasound records, 143/1711 (8.4%; 95% CI: 7.1–9.8) were preterm. Febrile illnesses in current pregnancy (adjusted risk ratio (aRR): 1.7; 95% CI: 1.1–2.8), a history of poor birth outcomes in prior pregnancy (aRR: 1.8; 95% CI: 1.3–2.4) and high blood pressure in pregnancy (aRR: 3.9, 95% CI: (1.7–9.2) were independently associated with adverse birth outcomes in a model that included age, education, human immunodeficiency virus status and high blood pressure at enrolment. Conclusion: We found similar rates of overall adverse birth outcomes, congenital anomalies, and small for gestational age but higher rates of stillbirths and lower rates of prematurity compared to the rates that have been reported in the sub-Saharan Africa region. However, the rates of adverse birth outcomes in this study were comparable to other studies conducted in Kenya. Febrile illnesses during the current pregnancy, previous history of poor birth outcomes and high blood pressure in pregnancy are predictive of an increased risk of adverse birth outcomes.

Objectives: With optimized antiretroviral treatment youth living with HIV (YLH) now spend most of their time in schools, making schools an important venue to optimize outcomes. We evaluated school support for YLH. Methods: We conducted surveys with public secondary/high schools in 3 Kenyan counties (Nairobi, Homa Bay, and Kajiado) to determine policies and training related to HIV. Chi‐squared tests and Poisson regression were used to compare policy availability and staff training by county HIV prevalence and school type. Results: Of 512 schools in the 3 counties, we surveyed 100. The majority (60%) of schools surveyed had boarding facilities. The median student population was 406 (IQR: 200, 775). Only half (49%) of schools had medication use policies; more in boarding than day schools (65% vs 30%, p =.003). While most schools (82%) had clinic attendance policies; policy availability was higher in higher HIV prevalence counties (Homa Bay [100%], Nairobi [82%], Kajiado [56%], p <.05). Overall, 64% had confidentiality policies with higher policy availability in higher HIV prevalence regions (p <.05). Few schools had staff trained in HIV‐related topics: HIV prevention (37%), HIV treatment (18%), HIV stigma reduction (36%). Few were trained in confidentiality (41%), psychosocial support (40%), or mental health (26%). Compared to day schools, boarding school were more likely to have staff trained in HIV prevention (prevalence ratio: 2.1 [95% confidence interval 1.0, 4.0], p =.037). Conclusion: In this survey of Kenyan schools, there were notable gaps in HIV care policy availability and training, despite high HIV burden. Development and implementation of national school HIV policies and staff training as well as strengthening clinic and family support may improve outcomes for YLH. [ABSTRACT FROM AUTHOR]
