Malaria risk and access to prevention and treatment in the paddies of the Kilombero Valley, Tanzania (Publications)
BACKGROUND: The Kilombero Valley is a highly malaria-endemic agricultural area in south-eastern Tanzania. Seasonal flooding of the valley is favourable to malaria transmission. During the farming season, many [...] nearest health services. This study assessed the impact of seasonal movements to remote fields on malaria risk and treatment-seeking behaviour. METHODS: A longitudinal study followed approximately 100 randomly [...] fever-risk. Mosquito nets usage and treatment of fever in health...
Rifampicin/Cotrimoxazole/Isoniazid versus mefloquine or quinine + sulfadoxine- pyrimethamine for malaria: a randomized trial1 (Publications)
multicentric noninferiority trial to assess the safety and efficacy of Cotrifazid against drug-resistant malaria in Papua New Guinea. DESIGN: The trial design was open-label, block-randomised, comparative, and [...] Sepik Province, Papua New Guinea. PARTICIPANTS: Patients of all ages with recurrent uncomplicated malaria were included. INTERVENTIONS: Patients were randomly assigned to receive Cotrifazid, mefloquine, [...] makes Cotrifazid in its current formulation and regimen a poor alternative...
MalariaSphere: a greenhouse-enclosed simulation of a natural <em>Anopheles gambiae</em> (Diptera: Culicidae) ecosystem in western Kenya (Publications)
BACKGROUND: The development and implementation of innovative vector control strategies for malaria control in Africa requires in-depth ecological studies in contained semi-field environments. This particularly [...] to significantly enhance our understanding of the behavioural and evolutionary ecology of African malaria vectors and our ability to develop and evaluate innovative control strategies. With regard to ge
Do health workers' preferences influence their practices? Assessment of providers' attitude and personal use of new treatment recommendations for... (Publications)
Tanzania changed malaria treatment policies twice within a decade. First in 2001 chloroquine (CQ) was replaced by sulfadoxine-pyrimethamine (SP) for management of uncomplicated malaria and by late 2006 [...] by enquiring which antimalarial was considered most suitable for the management of uncomplicated malaria for the three patient categories: i) children below 5; ii) older children and adults; and iii) pregnant [...] pregnant women. Practice was ascertained by asking which antimalarial was...
Malaria and its possible control on the island of Príncipe (Publications)
BACKGROUND: Malaria can be eradicated from islands. To assess the prospects for eradication of malaria from the island of Príncipe in the Gulf of Guinea, we fitted a mathematical model to age-prevalence [...] nets and mosquito-proofing of dwellings. In contrast to traditional malaria eradication strategies, this would avoid the risk of malaria epidemics because the reduction in R0 should be sustainable. [...] thus obtained estimates of the vectorial capacity and of the basic reproductive number...
Cell biological characterization of the malaria vaccine candidate trophozoite exported protein 1 (Publications)
extensive preclinical evaluation of its coiled coil peptides Tex1 was identified as promising novel malaria vaccine candidate providing the rational for a comprehensive cell biological characterization of
Varying efficacy of intermittent preventive treatment for malaria in infants in two similar trials: public health implications (Publications)
in the risk of clinical malaria between the second and the third dose; during the same period, there was no significant effect in Manhica. Similarly, protection against malaria episodes was maintained [...] explanation for the difference in IPTi efficacy on clinical malaria. Combination of IPTi and ITNs may be the most cost-effective tool for malaria control currently available, and needs to be explored in current [...] (IPTi) with sulphadoxine-pyrimethamine (SP) in infants resulted in different...
Population hemoglobin mean and anemia prevalence in Papua New Guinea: new metrics for defining malaria endemicity? (Publications)
estimating malaria endemicity and for monitoring malaria control strategies. The aim of this study is to compare population hemoglobin mean and anemia prevalence to established indicators of malaria endemicity [...] of enlarged spleens in children, and records of (presumptive) malaria diagnosis among populations living with different levels of malaria transmission. METHODOLOGY/PRINCIPAL FINDINGS: Convenience sample
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...
