Seasonal malaria chemoprevention and the spread of <em>Plasmodium falciparum </em>quintuple-mutant parasites resistant to sulfadoxine-pyrimethamine: a... (Publications)
BACKGROUND: Seasonal malaria chemoprevention (SMC) with sulfadoxine-pyrimethamine plus amodiaquine prevents millions of clinical malaria cases in children younger than 5 years in Africa's Sahel region [...] of quintuple-mutant parasites and the clinical consequences. METHODS: We used an individual-based malaria transmission model with explicit parasite dynamics and drug pharmacological models to identify and [...] deployment strategies. We estimated the impact of this spread on SMC effectiveness...
Climate change, malaria and neglected tropical diseases: a scoping review (Publications)
To explore the effects of climate change on malaria and 20 neglected tropical diseases (NTDs), and potential effect amelioration through mitigation and adaptation, we searched for papers published from [...] 1543 full-text papers were assessed. Of 511 papers meeting the inclusion criteria, 185 studied malaria, 181 dengue and chikungunya and 53 leishmaniasis; other NTDs were relatively understudied. Mitigation [...] (34%) and adaption strategies in 24 (5%). Amplitude and direction of effects of...
Severe outcomes of malaria in children under time-varying exposure (Publications)
Plasmodium falciparum severe malaria dataset to better understand the relationship between prevalence and incidence of malaria pediatric hospitalizations - a proxy of malaria severe outcomes- in East-Africa [...] In malaria epidemiology, interpolation frameworks based on available observations are critical for policy decisions and interpreting disease burden. Updating our understanding of the empirical evidence [...] dynamics, and subsequent protection patterns in children, substantially...
The impact of the scale-up of malaria rapid diagnostic tests on the routine clinical diagnosis procedures for febrile illness: a series of repeated... (Publications)
BACKGROUND: This paper examines the impact of the scale-up of malaria rapid diagnostic tests (RDT) on routine clinical diagnosis procedures for febrile illness in primary healthcare settings in Papua New [...] pre- and post-RDT scale-up and between febrile patients who tested either negative or positive for malaria infection by RDT (post scale-up only). RESULTS: A total of 1809 observations from 120 health facilities [...] scale-up has led to a reduction in body temperature measurement....
Screening a repurposing library, the Medicines for Malaria Venture Stasis Box, against <em>Schistosoma mansoni</em> (Publications)
development path, hence reducing costs and timelines. Promoting this approach, the Medicines for Malaria Venture (MMV) recently distributed a drug repurposing library of 400 advanced lead candidates (Stasis
GDV1 induces sexual commitment of malaria parasites by antagonizing HP1-dependent gene silencing (Publications)
Malaria is caused by Plasmodium parasites that proliferate in the bloodstream. During each replication cycle, some parasites differentiate into gametocytes, the only forms able to infect the mosquito vector [...] vector and transmit malaria. Sexual commitment is triggered by activation of AP2-G, the master transcriptional regulator of gametocytogenesis. Heterochromatin protein 1 (HP1)-dependent silencing of ap2-g
Drug use in the management of uncomplicated malaria in public health facilities in the Democratic Republic of the Congo (Publications)
BACKGROUND: Malaria the first causes of death from parasitic infection worldwide. Interventions to reduce the burden of malaria have produced a tremendous drop in malaria morbidity and mortality. However [...] performed. RESULTS: A total of 2300 files out of 3300 (69.7%) concerned uncomplicated malaria and were included in analysis. Malaria treatment was initiated after a positive RDT or microscopy in 51.5% of cases [...] However, progress is slower in DRC, which shares with Nigeria 39% of...
Malaria infection in mosquitoes decreases the personal protection offered by permethrin-treated bednets (Publications)
BACKGROUND: Insecticides targeting adult mosquitoes are the main way of controlling malaria. They work not only by killing mosquitoes, but also by repelling and irritating them. Indeed their repellent [...] repellent action gives valuable personal protection against biting mosquitoes. In the context of malaria control this personal protection is especially relevant when mosquitoes are infectious, whereas to protect [...] not yet infectious are killed (so, not repelled) by the insecticide. As the...
Appropriateness of malaria diagnosis and treatment for fever episodes according to patient history and anti-malarial blood measurement: a... (Publications)
survey took place between May and August 2015 in three regions of Tanzania with different levels of malaria endemicity. Interviews were conducted and blood samples were collected by dried blood spots through [...] testing when individuals attended care was defined as a patient with history of fever being tested for malaria and appropriate treatment as (i) having anti-malarial in the blood if the test result was positive [...] care and improve compliance to test result in order to target febrile...
