Sub-national stratification of malaria risk in mainland Tanzania: a simplified assembly of survey and routine data (Publications)
Recent malaria control efforts in mainland Tanzania have led to progressive changes in the prevalence of malaria infection in children, from 18.1% (2008) to 7.3% (2017). As the landscape of malaria transmission [...] incidence and fever test positivity rate for the period 2016-2017 as well as confirmed malaria incidence and malaria positivity in pregnant women for the period 2015-2017 were obtained from routine district [...] survey malaria information was developed. This pragmatic approach can...
Antigen-stimulated PBMC transcriptional protective signatures for malaria immunization (Publications)
accelerates and streamlines the development of vaccines. RTS,S/AS01E, the most clinically advanced malaria vaccine, has moderate efficacy in African children. In contrast, immunization with sporozoites under [...] cohorts and three African countries participating in an RTS,S/AS01E pediatric phase 3 trial and malaria-naïve individuals participating in a CPS trial. We identified both preimmunization and postimmunization
Dual plasmepsin-targeting antimalarial agents disrupt multiple stages of the malaria parasite life cycle (Publications)
Artemisin combination therapy (ACT) is the main treatment option for malaria, which is caused by the intracellular parasite Plasmodium. However, increased resistance to ACT highlights the importance of [...] achievable. Together, these show that dual PMIX and PMX inhibitors are promising candidates for malaria treatment and prevention.
The duration of chemoprophylaxis against malaria after treatment with artesunate-amodiaquine and artemether-lumefantrine and the effects of <em>pfmdr1... (Publications)
BACKGROUND: The majority of Plasmodium falciparum malaria cases in Africa are treated with the artemisinin combination therapies artemether-lumefantrine (AL) and artesunate-amodiaquine (AS-AQ), with a [...] amodiaquine being also widely used as part of seasonal malaria chemoprevention programs combined with sulfadoxine-pyrimethamine. While artemisinin derivatives have a short half-life, lumefantrine and a [...] reinfection. The estimated duration of chemoprophylaxis was then used in a...
Molecular malaria surveillance using a novel protocol for extraction and analysis of nucleic acids retained on used rapid diagnostic tests (Publications)
Acids from RDTs) approach; a complete workflow for large-scale molecular malaria surveillance. Using RDTs collected during a malaria indicator survey we demonstrated that ENAR provides a powerful tool to [...] The use of malaria rapid diagnostic tests (RDTs) as a source for nucleic acids that can be analyzed via nucleic acid amplification techniques has several advantages, including minimal amounts of blood [...] systematically developed and extensively evaluated a procedure to extract total...

As part of the revision, a mathematical malaria modelling framework for setting [...] study article describes the long-term use of modelling in close collaboration...
Prevalence and risk factors for malaria in pregnancy in Vanga, Democratic Republic of Congo (Publications)
(DRC) is the second most malarious country in the world, but little information is available on malaria control measures in pregnancy. We conducted a longitudinal study among 395 women pregnant with singletons [...] Vanga Health Zone, Kwilu Province. We recruited 406 pregnant women between April and October 2019. Malaria prevalence at recruitment was 18.8% in Vanga and 30.1% in Mayoko (difference p
Delayed cerebellar ataxia, a rare post-malaria neurological complication: case report and review of the literature (Publications)
Delayed cerebellar ataxia (DCA) is a rare post-malarial neurological complication with unknown pathomechanism characterized by its self-limiting course and favorable outcome. We report a case of DCA f
Estimating intervention effectiveness in trials of malaria interventions with contamination (Publications)
Background In cluster randomized trials (CRTs) or stepped wedge cluster randomized trials (SWCRTs) of malaria interventions, mosquito movement leads to contamination between trial arms unless buffer zones separate [...] s are provided as a function of intervention coverage. The methods are applied to two SWCRTs of malaria interventions, the SolarMal trial on the impact of mass trapping of mosquitoes with odor-baited traps [...] effectiveness as a function of coverage.
