OBJECTIVES To compare outcomes of antiretroviral therapy (ART) in South Africa, where viral load monitoring is routine, with those in Malawi and Zambia, where monitoring is based on CD4 cell counts. METHODS We included 18,706 adult patients starting ART in South Africa and 80,937 patients in Zambia or Malawi. We examined CD4 responses in models for repeated measures and the probability of swi...
Studies on environmental changes provide important insights into modes of speciation, into the (adaptive) reoccupation of ecological niches and into species turnover. Against this background, we here examine the history of the gastropod genus Lanistes in the African Rift Lake Malawi, guided by four general evolutionary scenarios, and compare it with patterns reported from other endemic Malawian...
Whole-Genome Scans Provide Evidence of Adaptive Evolution in Malawian Plasmodium falciparum Isolates
BACKGROUND Selection by host immunity and antimalarial drugs has driven extensive adaptive evolution in Plasmodium falciparum and continues to produce ever-changing landscapes of genetic variation. METHODS We performed whole-genome sequencing of 69 P. falciparum isolates from Malawi and used population genetics approaches to investigate genetic diversity and population structure and identify ...
INTRODUCTION Cholera still remains a significant cause of morbidity and mortality in developing countries, although comprehensive surveillance data to inform policy and strategies are scarce. METHODOLOGY A desk review of the national cholera database and zonal and districts reports was conducted. Interviews were conducted with district health management teams, health workers, and participants...
Background: A number of suspected endemic districts with Trachoma have not been mapped in Malawi, and this contributes to delays for scaling up trachoma control activities. Objectives: To determine the prevalence of trachoma and associated risk factors in one of the suspected endemic districts (Salima District) in central Malawi and to generate information to guide policy decisions. Methods: A ...
Quality of care of services provided to family planning clients is a source of major concern in reproductive health care, especially in resource-poor settings. It may be measured in terms of safety of the method or service provided and may be influenced by the knowledge, skills and experience of the service providers, the environment in which the services are provided and the care thereafter. A...
BACKGROUND Clinical officers perform much of major emergency surgery in Malawi, in the absence of medical officers. The aim of this study was to validate the advantages and disadvantages of delegation of major obstetric surgery to non-doctors. METHODS During a three month period, data from 2131 consecutive obstetric surgeries in 38 district hospitals in Malawi were collected prospectively. Th...
BACKGROUND Malawi is reassessing its HIV prevention strategy in the light of a limited reduction in the epidemic. No community based incidence studies have been carried out in Malawi, so estimates of where new infections are occurring require the use of mathematical models and knowledge of the size and sexual behaviour of different groups. The results can help to choose where HIV prevention int...
BACKGROUND Burnout among maternal healthcare workers in sub-Saharan Africa may have a negative effect on services provided and efforts to mitigate high maternal mortality rates. In Malawi, research on burnout is limited and no empirical research has been conducted specifically among maternal health staff. Therefore, the aims of the study were to examine the prevalence and degree of burnout repo...
Mapping distribution of lymphatic filariasis (LF) is a prerequisite for planning national elimination programmes. Results from a nation wide mapping survey for lymphatic filariasis (LF) in Malawi are presented. Thirty-five villages were sampled from 23 districts excluding three districts (Karonga, Chikwawa and Nsanje) that had already been mapped and Likoma, an Island, where access was not poss...
