Private commercial companies sharing health-relevant consumer data with health researchers in sub-Saharan Africa
Sharing large digital-first datasets, including for purposes for which they were not originally intended, is a hallmark of the 'big data revolution'. Through their routine operations, private commercial companies collect massive amounts of diverse data from their customers, some of which may interest those working in the public sector, such as health researchers. Researchers and government agencies worldwide have been increasingly using data from…
Understanding and processing informed consent during data-intensive health research in sub-Saharan Africa
Africa has a colonial past that renders it a linguistic melting pot, where language is not only important for communication but is inextricably related to cultural identity. In Africa, there are over 2000 languages that are still being used and spoken. Language diversity coupled with cultural diversity may affect the process of obtaining informed consent in data-intensive research. We explore some of the challenges and opportunities of multilingu…
The role of molecular xenomonitoring for assessing the impact of Ivermectin, Diethylcarbamazine Citrate and Albendazole triple-drug treatment against lymphatic filariasis
Lymphatic Filariasis (LF) is a mosquito-borne disease primarily caused by the filarial parasite Wuchereria bancrofti . The triple-drug therapy of Ivermectin, Diethylcarbamazine Citrate and Albendazole (IDA) has been adopted to accelerate LF elimination of LF as a public health problem, particularly in areas where onchocerciasis is not co-endemic. In Kenya, IDA was administered to endemic communities in Jomvu sub-County (Mombasa) and Lamu County i…
Cross-sectional study evaluating organizational climate, change commitment, and change efficacy for predicting family planning clinics’ success in increasing HIV counseling and testing in Mombasa, Ken…
Increasing HIV testing and counselling (HTC) is a first step to reducing HIV transmission. Implementing HTC in family planning (FP) clinics has been proposed to increase HIV testing coverage in at-risk populations. The Systems Analysis and Improvement Approach (SAIA) was used to improve HTC rates in FP clinics in Mombasa, Kenya. This hypothesis-generating exploratory analysis evaluated the associations between organizational climate characteristi…
Knowledge, Attitudes, and Subjective Norms Associated with Covid-19 Vaccination among Pregnant Women in Kenya
COVID-19 vaccination during pregnancy has been recommended, but the perceptions related to uptake remain unexplored. This pilot study aimed to explore how perceptions influence COVID-19 vaccine uptake among a sample of 115 pregnant women in Kenya, recruited via WhatsApp. Data were collected using an adapted online questionnaire between May and October 2022. Logistic analyses assessed the relationship between COVID-19 vaccination uptake and the Th…
Urinary interleukins (IL)-6 and IL-10 in schoolchildren from an area with low prevalence of Schistosoma haematobium infections in coastal Kenya
Urinary cytokines are gaining traction as tools for assessing morbidity in infectious and non-infectious inflammatory diseases of the urogenital tract. However, little is known about the potential of these cytokines in assessing morbidity due to S . haematobium infections. Factors that may influence the urinary cytokine levels as morbidity markers also remain unknown. Therefore the objective of the present study was to assess how urinary interleu…
Randomized controlled trial of a theory-informed mHealth intervention to support ART adherence and viral suppression among women with HIV in Mombasa, Kenya
This trial was registered with ClinicalTrials.gov (NCT02627365, 10/12/2015; http://clinicaltrials.gov )
Fertility Desire and Associations with Condomless Sex, Antiretroviral Adherence, and Transmission Potential in a Cohort of Kenyan Women Living with HIV in Sero-discordant Relationships
For women living with HIV (WLH) in serodiscordant partnerships, decisions about childbearing can challenge condom use and antiretroviral adherence. In a prospective cohort of 148 WLH in serodiscordant partnerships, 58 (39%) wanted more children in the future but were not currently trying to conceive (fertility desire), and 32 (22%) were currently trying to become pregnant (fertility intent). Detection of prostate specific antigen (PSA) in vaginal…
Magnitude and factors associated with post-tuberculosis lung disease in low- and middle-income countries
Background Emerging evidence suggests that after completion of treatment for tuberculosis (TB) a significant proportion of patients experience sequelae. However, there is limited synthesized evidence on this from low-income countries, from Sub-Saharan Africa, and in HIV infected individuals. We seek to provide an updated comprehensive systematic review and meta-analysis on the magnitude and factors associated with post-TB lung disease (PTLD) in l…
Adaptation of a social vulnerability index for measuring social frailty among East African women
The SVI-Kenya is a holistic index to measure social frailty among older women in Kenya, incorporating questions in multiple domains. Further research is needed to validate this adapted instrument
Allocation of scarce resources in Africa during Covid‐19
The COVID‐19 pandemic has raised important universal public health challenges. Conceiving ethical responses to these challenges is a public health imperative but must take context into account. This is particularly important in sub‐Saharan Africa (SSA). In this paper, we examine how some of the ethical recommendations offered so far in high‐income countries might appear from a SSA perspective. We also reflect on some of the key ethical challenges…
A Prospective Study of Depressive Symptoms, Condomless Sex, and HIV Viral Load in HIV-Positive Female Sex Workers in Kenya
Derivation of an HIV Risk Score for African Women Who Engage in Sex Work
What Could “Fair Allocation” during the Covid‐19 Crisis Possibly Mean in Sub‐Saharan Africa
The Covid‐19 pandemic has sparked rapid and voluminous production of bioethics commentary in popular media and academic publications. Many of the discussions are new twists on an old theme: how to fairly allocate scarce medical resources, such as ventilators and intensive care unit beds. In this essay, we do not add another allocation scheme to the growing pile, partly out of appreciation that such schemes should be products of inclusive and tran…
Growth patterns and their contributing factors among HIV‐exposed uninfected infants
With expanded HIV treatment and prevention programmes, most infants born to HIV-positive women are uninfected, but the patterns and determinants of their growth are not well described. This study aimed to assess growth patterns in a cohort of HIV-exposed uninfected (HEU) infants who participated in an experimental HIV vaccine trial and to test for associations with maternal and infant factors, including in-utero exposure to antiretroviral therapy…
Psychosocial Factors, Condomless Sex, and Detectable Viral Load in HIV-Positive Women in Serodiscordant Couples in Nairobi, Kenya
Risk indicators and effects of hypertension on HIV/Aids disease progression among patients seen at Kenyatta hospital HIV care center
There is paucity of data on prevalence of hypertension and its effects on HIV/AIDS progression among patients at Kenyatta National Hospital (KNH), Kenya. This was a cross sectional study conducted between January and May 2015 at the KNH HIV Care Centre. Ethical approval was obtained from institutional ethics review board. HIV positive adult patients were recruited sequentially, and written informed consent obtained from each participant. Systemat…
Risky Business
Limited research exists about condom failure as experienced by female sex workers. We conducted a qualitative study to examine how female sex workers in Mombasa, Kenya contextualise and explain the occurrence of condom failure. In-depth, semi-structured interviews were conducted with thirty female sex workers to ascertain their condom failure experiences. We qualitatively analysed interview transcripts to determine how the women mitigate risk and…
Adapting a stigma scale for assessment of tuberculosis-related stigma among English/Swahili-speaking patients in an African setting

An Evaluation of the Middle East Research Training Initiative Tool in Assessing Effective Functioning of Research Ethics Committees
The effective functioning of a research ethics committee (REC) can be evaluated using self-assessment tools. The Middle East Research Ethics Training Initiative (MERETI) tool can be used by one member, typically the Chair, to score an REC. The consistency of these scores across several members of an REC has never been evaluated. This study examined whether results would be consistent irrespective of who conducts the assessment. One REC's effectiv…
