  • Lessons Learned from Community Contact Tracing of Women Disengaged from an Urban Prevention of Mother-to-Child Transmission Program in Uganda

    Open AccessEllon Twinomuhwezi, Agnes N Kiragga et al.ARTICLEMaternal and Child Health Journal2026

    Community tracing for disengaged pregnant and post-partum women with HIV(PPWH) shows promise, yet few studies detail the practical challenges of tracing, particularly in the Prevention of Mother-to-Child Transmission programs (PMTCT). Standard guidelines and evidence-based approaches remain lacking. We share lessons from our experiences in tracing disengaged PPWH in an urban PMTCT program in Uganda, where nurse counselors joined outreach teams to…

  • Adaptation of the Client Diagnostic Questionnaire for East Africa

    Open AccessEdith Kamaru Kwobah, Suzanne Goodrich et al.ARTICLEPLOS Global Public Health2024

    Research increasingly involves cross-cultural work with non-English-speaking populations, necessitating translation and cultural validation of research tools. This paper describes the process of translating and criterion validation of the Client Diagnostic Questionnaire (CDQ) for use in a multisite study in Kenya and Uganda. The English CDQ was translated into Swahili, Dholuo (Kenya) and Runyankole/Rukiga (Uganda) by expert translators. The trans…

  • Characterizing participants who respond to text, email, phone calls, or postcards in a Sars-CoV-2 prevalence study

    Open AccessThomas J Duszynski, William F Fadel et al.ARTICLEBMC Public Health2024

    Researchers should be aware that the modality of contact as well as the number of prompts used could influence differential participation in public health studies. Our findings can inform researchers developing studies that rely on selective participation by study subjects. We explore how to increase participation within targeted demographic groups using specific modalities and examining frequency of contact

  • Effects of Alcohol Use on Patient Retention in HIV Care in East Africa

    Open AccessAlexa Monroy, Suzanne Goodrich et al.ARTICLEAIDS and Behavior2024

    We sought to investigate the association between hazardous alcohol use and gaps in care for people living with HIV over a long-term follow-up period. Adults who had participated in our previously published Phase I study of hazardous alcohol use at HIV programs in Kenya and Uganda were eligible at their 42 to 48 month follow-up visit. Those who re-enrolled were followed for an additional ~ 12 months. Hazardous alcohol use behavior was measured usi…

  • Effects of the Covid-19 pandemic on late postpartum women living with HIV in Kenya

    Open AccessJohn Humphrey, Marsha Alera et al.ARTICLEPLOS Global Public Health2023

    Although an estimated 1.4 million women living with HIV (WHIV) are pregnant each year globally, data describing the effects of the COVID-19 pandemic on postpartum women in low- and middle-income countries (LMICs) are limited. To address this gap, we conducted phone surveys among 170 WHIV ≥18 years and 18–24 months postpartum enrolled in HIV care at the Academic Model Providing Access to Healthcare in western Kenya, and assessed the effects of the…

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

    Open AccessJohn Humphrey, Julia Songok et al.ARTICLEAIDS and Behavior2022

    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…

  • Association of Health Status and Nicotine Consumption with Sars-CoV-2 positivity rates

    Open AccessThomas J Duszynski, William F Fadel et al.ARTICLEBMC Public Health2021

    In a statewide, community-based population drawn for SARS-CoV-2 testing, we find that overall health status was associated with infection rates. Unlike in studies of COVID-19 patients, smoking status was inversely associated with SARS-CoV-2 positivity. More research is needed to further understand the nature of this relationship
