Population pharmacokinetics of the antimalarial amodiaquine: a pooled analysis to optimize dosing (Publications)
Amodiaquine plus artesunate is the recommended antimalarial treatment in many malaria-endemic countries. However, pediatric doses are largely based on a linear extrapolation from adult doses. We pooled [...] amodiaquine, to optimize the dose across all age groups. Adults and children with uncomplicated malaria received daily weight-based doses of amodiaquine or artesunate-amodiaquine over three days. Plasma [...] 22.4% (15.6 - 31.9%) lower at the start of treatment than during convalescence,...
Semi-field evaluation of a volatile transfluthrin-based intervention reveals efficacy as a spatial repellent and evidence of other modes of action (Publications)
Presently, the most common malaria control tools-i.e., long lasting insecticide-treated nets (LLINs) and indoor residual spraying (IRS)-are limited to targeting indoor biting and resting behaviors of Anopheles [...] Anopheles mosquito species. Few interventions are targeted towards malaria control in areas where transmission is driven or persists due to outdoor biting behaviors. This study investigated a volatile [...] Southern Province, Zambia, is one such environment where outdoor biting is...
Evaluation of anopheline diversity and abundance across outdoor collection schemes utilizing cdc light traps in Nchelenge District, Zambia (Publications)
In the global fight against malaria, standard vector control methods such as indoor residual spraying (IRS) and insecticide-treated nets (ITNs) are intended to protect inside residential structures and [...] may be exposed to outdoors. Nchelenge District in northern Zambia experiences persistently high malaria transmission even with ITNs and IRS in place. However, very few studies have examined outdoor vector [...] including a number of infectious An. funestus, may partially explain the...
High proportions of asymptomatic and submicroscopic <em>Plasmodium vivax </em>infections in a peri-urban area of low transmission in the Brazilian... (Publications)
regional elimination, it is important to investigate the role of this asymptomatic reservoir in malaria transmission in peri-urban areas. This study aimed to estimate the prevalence of Plasmodium spp. [...] conducted including all inhabitants in a peri-urban area of Manaus, western Amazonas State, Brazil. Malaria parasites were detected by light microscopy (LM) and qPCR. Sexual stages of Plasmodium spp. were [...] carried gametocytes and presented low asexual parasitemia. This reservoir actively...
Asymptomatic <em>Plasmodium</em> infection and glycemic control in adults: results from a population-based survey in south-central Côte d'Ivoire (Publications)
associations of Plasmodium infection (PI) with fasting glucose (FG) and glycated hemoglobin (HbA1c) in malaria-endemic south-central Cote d'Ivoire. METHODS: We studied 979 participants (non-pregnant; no treated [...] Fasting venous blood was obtained for PI, FG, and HbA1c assessment. We defined PI as a positive malaria rapid diagnostic test (RDT) or microscopic identification of Plasmodium species. We applied multivariable [...] diagnosis in the presence of asymptomatic PI may misclassify or...

Socially-marketed rapid diagnostic tests and ACT in the private sector: ten years of experience in Cambodia (Publications)
some populations have recently experienced dramatic declines in malaria, the majority of those most at risk of Plasmodium falciparum malaria still lack access to effective treatment with artemisinin combination [...] which, in many countries, plays an important role in the provision of malaria treatment. The Affordable Medicines Facility for malaria (AMFm) is a recent initiative that aims to increase the provision of
Long-lasting insecticidal net (LLIN) ownership, use and cost of implementation after a mass distribution campaign in Kasai Occidental Province,... (Publications)
BACKGROUND: Long-lasting insecticidal nets (LLIN) are a highly effective means for preventing malaria infection and reducing associated morbidity and mortality. Mass free distribution campaigns have been [...] six months after the mass distribution. Descriptive statistics were used to measure changes in key malaria household indicators. LLIN ownership and use were compared between delivery strategies. Univariate [...] have a significant impact on LLIN use (69.6% [95% CI 63.1-75.5%] versus 65.7%...
Assessing whether universal coverage with insecticide-treated nets has been achieved: is the right indicator being used? (Publications)
(ITNs) are the primary tool for malaria vector control in sub-Saharan Africa, and have been responsible for an estimated two-thirds of the reduction in the global burden of malaria in recent years. While the [...] ITN for 2 people did not exceed 60% at the national level in any survey, except in Uganda's 2014 Malaria Indicator Survey (MIS). At 80% population ITN access, the expected proportion of households with [...] success of an ITN distribution programme. Under current ITN distribution...
