Access to artemisinin-based anti-malarial treatment and its related factors in rural Tanzania (Publications)
BACKGROUND: Artemisinin-based combination treatment (ACT) has been widely adopted as one of the main malaria control strategies. However, its promise to save thousands of lives in sub-Saharan Africa depends [...] of fever onset. In neither of the HDSS site was age, sex, socio-economic status or seasonality of malaria found to be significantly correlated with timely access. CONCLUSION: Timely access to authorized [...] major bottle neck and new more innovative interventions are needed to raise...
The influence of zinc supplementation on morbidity due to <em>Plasmodium falciparum</em>: a randomized trial in preschool children in Papua New Guinea (Publications)
determine the influence of zinc on malaria morbidity we conducted a randomized placebo-controlled trial of daily zinc supplementation in children residing in a malaria endemic region of Papua New Guinea [...] mg elemental zinc (n = 136) or placebo (n = 138) for 6 days a week for 46 weeks. Slide-confirmed malaria episodes were detected by surveillance of cases self-reporting to a local health center. Cross-sectional
Effect of large-scale social marketing of insecticide-treated nets on child survival in rural Tanzania (Publications)
BACKGROUND: Insecticide-treated nets have proven efficacy as a malaria-control tool in Africa. However, the transition from efficacy to effectiveness cannot be taken for granted. We assessed coverage and [...] programme for insecticide-treated nets in two rural districts of southern Tanzania with high perennial malaria transmission. METHODS: Socially marketed insecticide-treated nets were introduced step-wise over [...] INTERPRETATION: Social marketing of insecticide-treated nets has great...
Efficacy and safety of mefloquine, artesunate, mefloquine-artesunate, and praziquantel against <em>Schistosoma haematobium</em>: randomized,... (Publications)
Schistosoma who were treated with a mefloquine-artesunate combination against malaria might have a dual benefit: clearance of malaria parasitemia and reduction of schistosomiasis-related morbidity. CLINICAL [...] and praziquantel (40 mg/kg) against Schistosoma haematobium. The effects on Schistosoma mansoni, malaria parasitemia, soil-transmitted helminths, and intestinal protozoa were also determined. RESULTS: A
Human exposure to anopheline mosquitoes occurs primarily indoors, even for users of insecticide-treated nets in Luangwa Valley, south-east Zambia (Publications)
insecticidal products. We studied the human biting behaviour of the malaria vector Anopheles funestus Giles and the potential malaria vector Anopheles quadriannulatus Theobald in Luangwa valley, south-east [...] ABSTRACT: BACKGROUND: Current front line malaria vector control methods such as indoor residual spraying (IRS) and long-lasting insecticidal nets (LLINs), rely upon the preference of many primary vectors
Systematic review of indoor residual spray efficacy and effectiveness against <em>Plasmodium falciparum</em> in Africa (Publications)
Indoor residual spraying (IRS) is an important part of malaria control. There is a growing list of insecticide classes; pyrethroids remain the principal insecticide used in bednets but recently, novel [...] of different IRS insecticides. We report that long-lasting IRS formulations substantially reduce malaria, though their benefit over cheaper, shorter-lived formulations depends on local factors including

Etiology of anemia among infants, school-aged children, and young non-pregnant women in different settings of south-central Côte d'Ivoire (Publications)
samples were subjected to standardized quality-controlled methods. We found high prevalence of anemia, malaria, inflammation, and deficiencies of iron, riboflavin, and vitamin A but low prevalence and intensities [...] factor for anemia in non-pregnant women. Our findings call for interventions to protect infants from malaria, improved intake of dietary iron, and given the importance of anemia of inflammation in school-aged
Ancient Chinese methods are remarkably effective for the preparation of artemisinin-rich extracts of Qing Hao with potent antimalarial activity (Publications)
artemisinin is an important antimalarial drug and the herb itself is being grown and used locally for malaria treatment although this practice is controversial. Here we show that the ancient Chinese methods [...] in P. berghei infected mice. The implications of these results are discussed in the context of malaria treatment using A. annua infusions
Discovery and characterization of potent, efficacious, orally available antimalarial plasmepsin X inhibitors and preclinical safety assessment of... (Publications)
Plasmepsin X (PMX) is an essential aspartyl protease controlling malaria parasite egress and invasion of erythrocytes, development of functional liver merozoites (prophylactic activity), and blocking [...] days. This work demonstrates the potential to deliver PMX inhibitors with in vivo efficacy to treat malaria.
