Examining community perceptions of malaria to inform elimination efforts in Southern Mozambique: a qualitative study

In a background of renewed calls for malaria eradication, several endemic countries in sub-Saharan Africa are contemplating malaria elimination nationally or sub-nationally. In Mozambique, a strategy to elimin...

Funding Opportunity RFA-AI-20-064 from the NIH Guide for Grants and Contracts. The purpose of this initiative is to support research to advance understanding of the underlying immune mechanisms that contribute to malaria vaccine-elicited protection or vaccine hypo-responsiveness in endemic regions by capitalizing on recent research advances in systems vaccinology and systems immunology as well as emerging opportunities in data science and informatics. Multidisciplinary science and collaboration among investigators from the malaria vaccine research field and other relevant scientific areas are highly encouraged. The goal i...

Abstract Intermittent preventive treatment in pregnancy (IPTp) with monthly sulfadoxine-pyrimethamine (SP) is recommended for malaria-endemic parts of Africa, but efficacy is compromised by resistance and, in recent trials, dihydroartemisinin-piperaquine (DP) has shown better antimalarial protective efficacy. We utilized blood samples from a recent trial to evaluate selection by IPTp with DP or SP of Plasmodium falciparum genetic polymorphisms that alter susceptibility to these drugs. The prevalence of known genetic polymorphisms associated with altered drug susceptibility was determined in parasitemic samples, in...

AbstractPurpose of ReviewSequestration ofPlasmodium-infected cells in the placenta causes significant adverse effects on mothers and their fetuses. With progress in understanding placental malaria and associated adverse consequences, this review addresses the situation in an area with high prevalence, in Blue Nile State, Sudan, where protective interventions are not adequately provided.Recent FindingsSeveral studies have confirmed that malaria infection during pregnancy with parasites in the placenta, even at sub-patent level detected by molecular techniques, can result in maternal morbidity, fetal growth restriction, and ...

CONCLUSIONS: BK-SE36/CpG has an acceptable safety profile. Use of CpG-ODN(K3) greatly enhanced immunogenicity in malaria naïve Japanese adults when compared to BK-SE36 alone. The utility of BK-SE36/CpG is currently under evaluation in a malaria endemic setting in West Africa. TRIAL REGISTRATION: JMACCT Clinical Trial Registry JMA-IIA00109.

Abstract Chloroquine remains the first-line treatment for uncomplicated malaria in Haiti, and until recently, sulfadoxine-pyrimethamine was the second-line treatment. A few studies have reported the presence of molecular markers for resistance in Plasmodium falciparum parasites, and in vivo therapeutic efficacy studies (TESs) have been limited. Recognizing the history of antimalarial resistance around the globe and the challenges of implementing TESs in low-endemic areas, the Ministry of Health established a surveillance program to detect molecular markers of antimalarial resistance in Haiti. Sentinel sites were p...

Conclusion: The overall performance of the kit was below the WHO standard. Further study on a large sample size is recommended to be carried out in the study area to use the test kit instead of microscopy for malaria diagnosis. Providing training on quality malaria laboratory diagnosis and availing necessary supplies for malaria diagnosis shall also be considered. PMID: 32963553 [PubMed]
