  • How to make an app-based program work and show how it works

    Open AccessRicky Janssen, Nora Engel et al.ARTICLEPLOS Global Public Health2025

    For digital health interventions, the “gold standard” of evaluating effectiveness is the randomized control trial (RCT). Yet, RCT methodology presents issues such as precluding changes to the technology during the study period as well as the use of study settings that do not reflect “real world” contexts. In this paper, we draw on empirical material from our ethnographic research on an app-based program called HIVSmart!, which is a digital strate…

  • Self-tests for Covid-19

    Open AccessApoorva Anand, Fiorella Vialard et al.ARTICLEPLOS Global Public Health2024

    COVID-19 self-testing strategy (COVIDST) can rapidly identify symptomatic and asymptomatic SARS-CoV-2-infected individuals and their contacts, potentially reducing transmission. In this living systematic review, we evaluated the evidence for real-world COVIDST performance. Two independent reviewers searched six databases (PubMed, Embase, Web of Science, World Health Organization database, Cochrane COVID-19 registry, Europe PMC) for the period Apr…

  • Socioeconomic factors impact the risk of HIV acquisition in the township population of South Africa

    Open AccessCindy Leung Soo, Nitika Pant Pai et al.ARTICLEPLOS Global Public Health2023

    With a prevalence almost twice as high as the national average, people living in South African townships are particularly impacted by the HIV epidemic. Yet, it remains unclear how socioeconomic factors impact the risk of HIV infection within township populations. Our objective was to estimate the extent to which socioeconomic factors (dwelling situation, education, employment status, and monthly income) explain the risk of HIV in South African to…

  • Safety and efficacy of the ChAdOx1 nCoV-19 vaccine (AZD1222) against Sars-CoV-2

    Open AccessMerryn Voysey, Sue Ann Costa Clemens et al.ARTICLEThe Lancet2021

    Background A safe and efficacious vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), if deployed with high coverage, could contribute to the control of the COVID-19 pandemic. We evaluated the safety and efficacy of the ChAdOx1 nCoV-19 vaccine in a pooled interim analysis of four trials. Methods This analysis includes data from four ongoing blinded, randomised, controlled trials done across the UK, Brazil, and South Afri…

  • Impact of a personalised, digital, HIV self-testing app-based program on linkages and new infections in the township populations of South Africa

    Open AccessNitika Pant Pai, Aliasgar Esmail et al.ARTICLEBMJ Global Health2021

    INTRODUCTION: Implementation data for digital unsupervised HIV self-testing (HIVST) are sparse. We evaluated the impact of an app-based, personalised, oral HIVST program offered by healthcare workers in Western Cape, South Africa. METHODS: In a quasirandomised study (n=3095), we recruited consenting adults with undiagnosed HIV infection from township clinics. To the HIVST arm participants (n=1535), we offered a choice of an offsite (home, office …

  • Moments of Uncertainty

    Open AccessRicky Janssen, Anja Krumeich et al.ARTICLEMedicine Anthropology Theory2021

    Feasibility and acceptability research for HIV self-testing (HIVST) often emphasises the importance of good test conduct and correct test interpretation for knowing one's HIV result while overlooking the ways in which different uncertainties and meanings emerge around testing. Using empirical examples from a quantitative study assessing an app-based strategy in Cape Town, South Africa, this research article explores the practice of HIVST and how …

  • You're only there on the phone'? A qualitative exploration of community, affect and agential capacity in HIV self-testing using a smartphone app

    Open AccessRicky Janssen, Nora Engel et al.ARTICLESociology of Health & Illness2021Citada por: 1Referencias: 4

    Mobile health (mHealth) technologies for HIV care are developed to provide diagnostic support, health education, risk assessment and self-monitoring. They aim to either improve or replace part of the therapeutic relationship. Part of the therapeutic relationship is affective, with the emergence of feelings and emotion, yet little research on mHealth for HIV care focuses on affect and HIV testing practices. Furthermore, most of the literature expl…

  • Evaluating Latent Tuberculosis Infection Test Performance Using Latent Class Analysis in a TB and HIV Endemic Setting

    Open AccessShahieda Adams, Rodney Ehrlich et al.ARTICLEInternational Journal of…2019

    In an endemic setting a positive TST or IGRA was highly predictive of LTBI, while a combination of TST and IGRA had high rule-out value. These data inform the utility of LTBI-related immunodiagnostic tests in TB and HIV endemic settings

  • Alone But Supported

    Open AccessRicky Janssen, Nora Engel et al.ARTICLEAIDS and Behavior2019

    HIV self-testing has the potential to improve test access and uptake, but concerns remain regarding counselling and support during and after HIV self-testing. We investigated an oral HIV self-testing strategy together with a mobile phone/tablet application to see if and how it provided counselling and support, and how it might impact test access. This ethnographic study was nested within an ongoing observational cohort study in Cape Town, South A…

  • Longitudinal assessment of health related quality of life of HIV infected patients treated for tuberculosis and HIV in a high burden setting

    Open AccessThuli Mthiyane, Alexander S Pym et al.ARTICLEQuality of Life Research2016

  • Supervised and Unsupervised Self-Testing for HIV in High- and Low-Risk Populations

  • EDCTP regional networks of excellence

    Open AccessGeorge M Miiro, Odile Ouwe Missi Oukem‐Boyer et al.ARTICLEBMC Public Health2013

    The shared initial merits and lessons learnt portray in part the strengthened capacity of these networks for improved research coordination and conduct of planned multi-center clinical trials in Africa. Increased funding by African agencies, governments and international health partners will ensure sustainability of these networks for research capacity development and demonstrate their commitment to achieving the MDGs in Africa
