Human leukocyte antigen-DQA1*04:01 and rs2040406 variants are associated with elevated risk of childhood Burkitt lymphoma.

Burkitt lymphoma (BL) is responsible for many childhood cancers in sub-Saharan Africa, where it is linked to recurrent or chronic infection by Epstein-Barr virus or Plasmodium falciparum. However, whether human leukocyte antigen (HLA) polymorphisms, which regulate immune response, are associated with BL has not been well investigated, which limits our understanding of BL etiology. Here we investigate this association among 4,645 children aged 0-15 years, 800 with BL, enrolled in Uganda, Tanzania, Kenya, and Malawi.

Characterizing mobility patterns and malaria risk factors in semi-nomadic populations of Northern Kenya.

While many studies have characterized mobility patterns and disease dynamics of individuals from settled populations, few have focused on more mobile populations. Highly mobile groups are often at higher disease risk due to their regular movement that may increase the variability of their environments, reduce their access to health care, and limit the number of intervention strategies suitable for their lifestyles. Quantifying the movements and their associated disease risks will be key to developing intervention strategies more suitable for mobile populations.

Lifting all boats: strategies to promote equitable bidirectional research training opportunities to enhance global health reciprocal innovation.

Inequities in global health research are well documented. For example, training opportunities for US investigators to conduct research in low-income and middle-income countries (LMIC) have exceeded opportunities for LMIC investigators to train and conduct research in high-income countries. Reciprocal innovation addresses these inequities through collaborative research across diverse global settings.

Preferences of Pregnant and Postpartum Women for Differentiated Service Delivery in Kenya.

Background: Differentiated service delivery models are implemented by HIV care programs globally, but models for pregnant and postpartum women living with HIV (PPWH) are lacking. We conducted a discrete choice experiment to determine women's preferences for differentiated service delivery.

Setting: Five public health facilities in western Kenya.

Ethical Considerations for Engaging Children and Adolescents Living with HIV in Research in African Countries: A Systematic Review.

Research engaging children and adolescents living with HIV (CALWH) is critical for youth-friendly services and HIV care, and researchers need to ensure that such engagement is ethical. We conducted a systematic review to identify key ethical considerations for the engagement of CALWH in research. The review focused on primary research articles conducted in African countries that examined ethical issues in CALWH engaged in research.

Assessing HIV-infected patient retention in a program of differentiated care in sub-Saharan Africa: a G-estimation approach.

Differentiated care delivery aims to simplify care of people living with HIV, reflect their preferences, reduce burdens on the healthcare system, maintain care quality and preserve resources. However, assessing program effectiveness using observational data is difficult due to confounding by indication and randomized trials may be infeasible. Also, benefits can reach patients directly, through enrollment in the program, and indirectly, by increasing quality of and accessibility to care.

Ethical Considerations for Engaging Youth Living with HIV in Research: Perspectives from Youth, Their Caregivers and Subject Matter Experts in Kenya.

Engaging youth living with HIV (YLWH) in research is critical to improving HIV-related outcomes, but their involvement raises unaddressed bioethical questions. This study used qualitative inquiry with Kenyan YLWH, caregivers, and subject matter experts (SMEs) to evaluate ethical considerations and strategies for research involving YLWH. Interviews were conducted with 99 participants: 40 YLWH (median age 17.

Supply-side and demand-side factors influencing uptake of malaria testing services in the community: lessons for scale-up from a post-hoc analysis of a cluster randomised, community-based trial in western Kenya.

Objectives: Maximising the impact of community-based programmes requires understanding how supply of, and demand for, the intervention interact at the point of delivery.

Design: Post-hoc analysis from a large-scale community health worker (CHW) study designed to increase the uptake of malaria diagnostic testing.

Setting: Respondents were identified during a household survey in western Kenya between July 2016 and April 2017.

Genotypes and Risk of Childhood Burkitt Lymphoma in East Africa.

Interferon lambda 4 (IFN-λ4) is a novel type-III interferon that can be expressed only by carriers of the genetic variant rs368234815-dG within the first exon of the gene. Genetic inability to produce IFN-λ4 (in carriers of the rs368234815-TT/TT genotype) has been associated with improved clearance of hepatitis C virus (HCV) infection. The IFN-λ4-expressing rs368234815-dG allele (-dG) is most common (up to 78%) in West sub-Saharan Africa (SSA), compared to 35% of Europeans and 5% of individuals from East Asia.

A case report of a 16-year-old male with extrapulmonary tuberculosis presenting as multiloculated mediastinal, pleural, and paravertebral fluid collections with chest pain, Eldoret, Kenya.

Key Clinical Message: Extrapulmonary TB presenting as multiloculated pleural fluid collections is rare in persons less than 18 years of age, but it can occur. High index of suspicion is important in establishing early diagnosis and treatment to reduce morbidity and mortality.

Abstract: We present a case report of an immunocompetent African young man who presented with persistent chest pain and fever, and was diagnosed with extrapulmonary tuberculosis (EPTB) following chest CT scan, pleural biopsy histopathology examination, and Ziehl-Neelsen (ZN) staining, and pleural fluid Gene Xpert studies.

A pragmatic approach to equitable global health partnerships in academic health sciences.

Global partnerships offer opportunities for academic departments in the health sciences to achieve mutual benefits. However, they are often challenged by inequities in power, privilege and finances between partners that have plagued the discipline of global health since its founding. In this article, a group of global health practitioners in academic medicine offer a pragmatic framework and practical examples for designing more ethical, equitable and effective collaborative global relationships between academic health science departments, building on the principles laid out by the coalition Advocacy for Global Health Partnerships in the Brocher declaration.

HIV-Related Stigma Shapes Research Participation for Youth Living With HIV in Kenya.

HIV stigma affects medication adherence, psychosocial outcomes, and clinical management for youth living with HIV (YLWH). We explored the impact of HIV stigma on research participation, to inform the ethical engagement of this vulnerable group. We interviewed 40 YLWH, 20 caregivers, and 39 subject matter experts (SMEs); transcripts were analyzed by HK and EG, with emerging themes confirmed by JA and AC.

Plasmodium falciparum importation does not sustain malaria transmission in a semi-arid region of Kenya.

Human movement impacts the spread and transmission of infectious diseases. Recently, a large reservoir of Plasmodium falciparum malaria was identified in a semi-arid region of northwestern Kenya historically considered unsuitable for malaria transmission. Understanding the sources and patterns of transmission attributable to human movement would aid in designing and targeting interventions to decrease the unexpectedly high malaria burden in the region.

Psychometric properties of the mini international neuropsychiatric interview (MINI) psychosis module: a Sub-Saharan Africa cross country comparison.

Background: The Mini International Neuropsychiatric Inventory 7.0.2 (MINI-7) is a widely used tool and known to have sound psychometric properties; but very little is known about its use in low and middle-income countries (LMICs).

Intravenous ketamine for severe alcohol use disorder at Moi Teaching & Referral Hospital, Kenya: a case report.

Background: Alcohol use disorder is prevalent globally and in Kenya, and is associated with significant health and socio-economic consequences. Despite this, available pharmacological treatment options are limited. Recent evidence indicates that intravenous (IV) ketamine can be beneficial for the treatment of alcohol use disorder, but is yet to be approved for this indication.

Burkitt lymphoma risk shows geographic and temporal associations with infections in Uganda, Tanzania, and Kenya.

Endemic Burkitt lymphoma (eBL) is a pediatric cancer coendemic with malaria in sub-Saharan Africa, suggesting an etiological link between them. However, previous cross-sectional studies of limited geographic areas have not found a convincing association. We used spatially detailed data from the Epidemiology of Burkitt Lymphoma in East African Children and Minors (EMBLEM) study to assess this relationship.

Integrating community-based HIV and non-communicable disease care with microfinance groups: a feasibility study in Western Kenya.

Background: The Harambee study is a cluster randomized trial in Western Kenya that tests the effect, mechanisms, and cost-effectiveness of integrating community-based HIV and non-communicable disease care within microfinance groups on chronic disease treatment outcomes. This paper documents the stages of our feasibility study conducted in preparation for the Harambee trial, which include (1) characterizing the target population and gauging recruitment capacity, (2) determining community acceptability of the integrated intervention and study procedures, and (3) identifying key implementation considerations prior to study start.

Methods: Feasibility research took place between November 2019 and February 2020 in Western Kenya.

Genetic structure correlates with ethnolinguistic diversity in eastern and southern Africa.

African populations are the most diverse in the world yet are sorely underrepresented in medical genetics research. Here, we examine the structure of African populations using genetic and comprehensive multi-generational ethnolinguistic data from the Neuropsychiatric Genetics of African Populations-Psychosis study (NeuroGAP-Psychosis) consisting of 900 individuals from Ethiopia, Kenya, South Africa, and Uganda. We find that self-reported language classifications meaningfully tag underlying genetic variation that would be missed with consideration of geography alone, highlighting the importance of culture in shaping genetic diversity.

Increasing diversity in genomics requires investment in equitable partnerships and capacity building.

Calls for diversity in genomics have motivated new global research collaborations across institutions with highly imbalanced resources. We describe practical lessons we have learned so far from designing multidisciplinary international research and capacity-building programs that prioritize equity in two intertwined programs — the NeuroGAP-Psychosis research study and GINGER training program — spanning institutions in Ethiopia, Kenya, South Africa, Uganda and the united States.

A Challenging Knowledge Gap: Estimating Modes of HIV Acquisition Among Adolescents Entering HIV Care During Adolescence.

Characterizing HIV acquisition modes among adolescents with HIV (AHIV) enrolling in care during adolescence is a challenging gap that impacts differential interventions. We explored whether primary data collection with targeted questionnaires may address this gap and improve understanding of risk factors and perceptions about adolescents' HIV acquisition, in Kenyan AHIV entering care at ≥10 years, and their mothers with HIV (MHIV). Clinical data were derived through chart review.

"I have never talked to anyone to free my mind" - challenges surrounding status disclosure to adolescents contribute to their disengagement from HIV care: a qualitative study in western Kenya.

Introduction: Adolescents living with HIV (ALHIV, ages 10-19) experience complex barriers to care engagement. Challenges surrounding HIV status disclosure or non-disclosure to adolescents may contribute to adolescent disengagement from HIV care or non-adherence to ART. We performed a qualitative study to investigate the contribution of disclosure challenges to adolescent disengagement from HIV care.

Retention in care and viral suppression in the PMTCT continuum at a large referral facility in western Kenya.

Medical records of pregnant and postpartum women living with HIV and their infants attending a large referral facility in Kenya from 2015 to 2019 were analyzed to identify characteristics associated with retention in care and viral suppression. Women were stratified based on the timing of HIV care enrollment: known HIV-positive (KHP; enrolled pre-pregnancy) and newly HIV-positive (NHP; enrolled during pregnancy). Associations with retention at 18 months postpartum and viral suppression (< 1000 copies/mL) were determined.
