  • Advancing Early Warning Systems for Malaria

    Open AccessDonnie Mategula, Judy Gichuki et al.ARTICLEPLOS Global Public Health2025

    Malaria Early Warning Systems (EWS) are predictive tools that often use climatic and other environmental variables to forecast malaria risk and trigger timely interventions. Despite their potential benefits, the development and implementation of malaria EWS face significant challenges and limitations. We reviewed the current evidence on malaria EWS, including their settings, methods, performance, actions, and evaluation. We conducted a comprehens…

  • Characterisation of populations at risk of sub-optimal dosing of artemisinin-based combination therapy in Africa

    Open AccessAbena Takyi, Verena I Carrara et al.ARTICLEPLOS Global Public Health2023

    Selection of resistant malaria strains occurs when parasites are exposed to inadequate antimalarial drug concentrations. The proportion of uncomplicated falciparum malaria patients at risk of being sub-optimally dosed with the current World Health Organization (WHO) recommended artemisinin-based combination therapies (ACTs) is unknown. This study aims to estimate this proportion and the excess number of treatment failures (recrudescences) associa…

  • Misrepresentation of research on academic promotions at the University of Cape Town

    Open AccessRobert Morrell, Karen Barnes et al.ARTICLECogent Social Sciences2020

    In this response, we address the misrepresentation of our article by Rene W Albertus on higher education decolonisation processes in South Africa. We respond to her claim, based on a misreading of our article, that at the University of Cape Town white academic staff are promoted faster than black staff and restate the major findings of our quantitative analysis of 11 years of promotion data. We used time to promotion as a proxy for fairness to ex…

  • Beyond evidence

    Open AccessDavid N Dürrheim, Holly Ann Williams et al.ARTICLECritical Public Health2003

    There is a growing appreciation that decisions on changing drug treatment policy should be based on robust evidence of drug effectiveness. No published information describing the process of decision making prior to malaria treatment policy changes or subsequent success in implementing treatment policy changes exists in South Africa. This retrospective study of the differential implementation of a policy change from chloroquine to sulphadoxine-pyr…

  • Transcultural Nursing Practice Described by Registered Nurses and Baccalaureate Nursing Students

    Open AccessArdelina Baldonado, Ardelina A Baldonado et al.ARTICLEJournal of Transcultural Nursing1998

    Using Leininger's Theory of Culture Care Diversity and Universality as a framework, this research examined transcultural practices of nurses and students. A survey was administered to a convenience sample of registered nurses and senior baccalaureate students with 767 usable questionnaires returned. Neither group expressed confidence in their ability to care for culturally-diverse patients. Registered nurses (RNs) reported assessing cultural fact…
