Hemolysis after oral artemisinin combination therapy for uncomplicated <em>Plasmodium falciparum</em> malaria (Publications)
weeks after treatment of severe malaria with intravenous artesunate have been described. We performed a prospective observational study of patients with uncomplicated malaria to investigate whether posttreatment [...] occurs after oral artemisinin-based combination therapy. Eight of 20 patients with uncomplicated malaria who were given oral artemisinin-based combination therapy met the definition of posttreatment hemolysis [...] g/dL; p = 0.002). These findings indicate a need for increased...
Mass mosquito trapping for malaria control in western Kenya: study protocol for a stepped wedge cluster-randomised trial (Publications)
of malaria threaten the efficacy of existing vector control tools used against malaria mosquitoes. The development of odour-baited mosquito traps has led to the possibility of controlling malaria through [...] mass mosquito trapping could be an effective tool for elimination of malaria. If proven to be effective, this novel approach to malaria control would be a valuable addition to the existing strategies of [...] through mass trapping of malaria vectors. Through daily removal trapping against...
Evaluation of malaria diagnoses using a handheld light microscope in a community-based setting in rural Côte d'Ivoire (Publications)
Portable microscopy may facilitate quality diagnostic care in resource-constrained settings. We compared a handheld light microscope (Newton Nm1) with a mobile phone attachment to conventional light m
Pregnant women and infants as sentinel populations to monitor prevalence of malaria: results of pilot study in Lake Zone of Tanzania (Publications)
screened for malaria infection using a malaria rapid diagnostic test (RDT) from December 2012 to November 2013, regardless of symptoms. Participants who tested positive were treated for malaria per national [...] BACKGROUND: As malaria control interventions are scaled-up, rational approaches are needed for monitoring impact over time. One proposed approach includes monitoring the prevalence of malaria infection among [...] facility (HF) visits. This pilot explored the feasibility and utility of...
Mapping intra-urban malaria risk using high resolution satellite imagery: a case study of Dar es Salaam (Publications)
of malaria in rapidly growing African urban settlements. The complex and heterogeneous nature of urban malaria requires a better understanding of the spatial and temporal patterns of urban malaria risk [...] localized heterogeneity of malaria transmission and develop a high resolution predictive malaria risk map of Dar es Salaam. RESULTS: Results indicate that the risk of malaria infection varied across the [...] settlements by 2030, the burden of malaria among urban populations in Africa...
Interventions that effectively target <em>Anopheles funestus</em> mosquitoes could significantly improve control of persistent malaria transmission in... (Publications)
Malaria is transmitted by many Anopheles species whose proportionate contributions vary across settings. We re-assessed the roles of Anopheles arabiensis and Anopheles funestus, and examined potential [...] potential benefits of species-specific interventions in an area in south-eastern Tanzania, where malaria transmission persists, four years after mass distribution of long-lasting insecticide-treated nets (LLINs) [...] arabiensis (44.1%). Though An. arabiensis is still the most abundant vector...
The economics of malaria control and elimination: a systematic review (Publications)
cost of malaria control to a health system ranged from $0.11 to $39.06 (median: $2.21) while that for malaria elimination ranged from $0.18 to $27 (median: $3.00). BCRs of investing in malaria control [...] competing health priorities threaten the sustainability of malaria programmes. Elucidating the cost and benefits of continued investments in malaria could encourage sustained political and financial commitments [...] financial cost and return of malaria control, elimination and eradication....
Transcriptional profiling defines histone acetylation as a regulator of gene expression during human-to-mosquito transmission of the malaria parasite... (Publications)
Transmission of the malaria parasite Plasmodium falciparum from the human to the mosquito is mediated by the intraerythrocytic gametocytes, which, once taken up during a blood meal, become activated to [...] essential role of histone acetylation for gene regulation in gametocytes, which can be exploited for malaria transmission-blocking interventions.
