Bayesian geostatistical modelling of malaria and lymphatic filariasis infections in Uganda: predictors of risk and geographical patterns of... (Publications)
BACKGROUND: In Uganda, malaria and lymphatic filariasis (causative agent Wuchereria bancrofti) are transmitted by the same vector species of Anopheles mosquitoes, and thus are likely to share common e [...] children for circulating filarial antigens (CFA). Concurrently, blood smears were examined for malaria parasites. In this study, the resultant malariological data are analysed for the first time and the [...] different random effects to allow for spatial structuring and to capture potential...
A research agenda for malaria eradication: diagnoses and diagnostics (Publications)
or absent malaria transmission, sustaining interest in elimination and maintaining resources will become increasingly important. Thus, research is required into the context in which malaria diagnostic [...] Many of malaria's signs and symptoms are indistinguishable from those of other febrile diseases. Detection of the presence of Plasmodium parasites is essential, therefore, to guide case management. Improved
Estimation of heterogeneity in malaria transmission by stochastic modelling of apparent deviations from mass action kinetics (Publications)
BACKGROUND: Quantifying heterogeneity in malaria transmission is a prerequisite for accurate predictive mathematical models, but the variance in field measurements of exposure overestimates true micro [...] challenge by infectious vectors. This appears to violate the principle of mass action that is implied by malaria biology. Micro-heterogeneity may be the reason for this anomaly. It is proposed that the level of [...] exposure. METHODS: The relationship between the entomological inoculation...
Design and pre-clinical profiling of a <em>Plasmodium falciparum</em> MSP-3 derived component for a multi-valent virosomal malaria vaccine (Publications)
BACKGROUND: Clinical profiling of two components for a synthetic peptide-based virosomal malaria vaccine has yielded promising results, encouraging the search for additional components for inclusion in [...] is suitable for use in humans and represents a candidate component for a virosomal multi-valent malaria subunit vaccine
Impact of promoting longer-lasting insecticide treatment of bed nets upon malaria transmission in a rural Tanzanian setting with pre-existing high... (Publications)
experienced extremely high malaria transmission in the 1990s. By 2001-03, following high usage rates (75% of all age groups) of untreated bed nets, a 4.2-fold reduction in malaria transmission intensity was [...] Anopheles arabiensis was only 38%. CONCLUSION: Insecticide treatment of nets reduced the intensity of malaria transmission in addition to that achieved by the untreated nets alone. Impacts were most pronounced

The PE (compared to placebo) against clinical malaria episodes (caused by all species) was [...] No rebound in malaria morbidity was observed for 6 mo following the intervention. CONCLUSIONS: IPTi using a long half-life drug combination is efficacious for the prevention of malaria and anemia in infants [...] Intermittent preventive treatment in infants (IPTi) has been shown in...
Modeling the public health impact of malaria vaccines for developers and policymakers (Publications)

This paper describes a Malaria Vaccine [...] BACKGROUND: Efforts to develop malaria vaccines show promise. Mathematical model-based estimates of the potential demand, public health impact, and cost and financing requirements can be used to inform [...] functionality was demonstrated by estimating the public health impact of a...
Over-diagnosis of malaria by microscopy in the Kilombero Valley, Southern Tanzania: an evaluation of the utility and cost-effectiveness of rapid... (Publications)

METHODS: [...] and accurate diagnosis of febrile patients is essential to treat uncomplicated malaria cases properly, prevent severe malaria, and avert unnecessary anti-malarial treatments. Improper use of anti-malarials [...] estimating the extent of malaria over-diagnosis and over-treatment with...
Population pharmacokinetics of mefloquine, piperaquine and artemether-lumefantrine in Cambodian and Tanzanian malaria patients (Publications)
BACKGROUND: Inter-individual variability in plasma concentration-time profiles might contribute to differences in anti-malarial treatment response. This study investigated the pharmacokinetics of thre

The revised protocol stipulates routine testing of malaria infection [...] observation instrument. RESULTS: Overall, 15% of observed fever patients (n=468) were tested for malaria infection by rapid diagnostic test and a further 3.6% were tested via microscopy. An anti-malarial [...] what they might look like were discussed in only 1.1% of cases. CONCLUSION:...
