Effect of mass dihydroartemisinin-piperaquine administration in southern Mozambique on the carriage of molecular markers of antimalarial resistance

PLos ONE; 15 (10), 2020
Background Mass drug administration (MDA) can rapidly reduce the burden of Plasmodium falciparum (Pf). However, concerns remain about its contribution to select for antimalarial drug resistance. Methods We used Sanger sequencing and real-time PCR to determine the proportion of molecular markers associate...

A Balanced Proinflammatory and Regulatory Cytokine Signature in Young African Children Is Associated With Lower Risk of Clinical Malaria

Clin. infect. dis; 69 (Sep.2019), 2019
The effect of timing of exposure to first Plasmodium falciparum infections during early childhood on the induction of innate and adaptive cytokine responses and their contribution to the development of clinical malaria immunity is not well established. As part of a double-blind, randomized, placebo-contr...

Differential patterns of disease and injury in Mozambique: New perspectives from a pragmatic, multicenter, surveillance study of 7809 emergency presentations

PLOS ONE; 14 (7), 2019
There is a paucity of primary data to understand the overall pattern of disease and injuries as well as related health-service utilization in resource-poor countries in Africa. To generate reliable and robust data describing the pattern of emergency presentations attributable to communicable disease (CD)...

Malaria, immunity and mental disorders: A plausible relationship?

EBioMedicine; 40 (), 2019
Malaria is the most common and dangerous parasitic disease, being responsible every year for nearly half a million deaths, and an estimated 219 million clinical cases, globally [1]. The devastating short-term effects that an acute malarial infection can have on any given individual have been historically...

Severe malnutrition among children under the age of 5 years admitted to a rural district hospital in southern Mozambique

Public health nutr; 16 (9), 2013
Objective: To describe the burden, clinical characteristics and prognostic factors of severe malnutrition in children under the age of 5 years. Design: Retrospective study of hospital-based data systematically collected from January 2001 to December 2010. Setting: Rural Mozambican district hospital. Subj...

Pyruvate kinase deficiency in sub-Saharan Africa: identification of a highly frequent missense mutation (G829A; Glu277Lys) and association with malaria

PLos ONE; 7 (10), 2012
Background: Pyruvate kinase (PK) deficiency, causing hemolytic anemia, has been associated to malaria protection and its prevalence in sub-Saharan Africa is not known so far. This work shows the results of a study undertaken to determine PK deficiency occurrence in some sub-Saharan African countries, as ...

Entomological characteristics of malaria transmission in Manhiça, a rural area in southern Mozambique

J. med. entomol; 42 (2), 2005
From October 1997 to September 1998, an entomological survey was carried out in Manhiça, Mozambique, to describe the anopheline population and intensity of malaria transmission. Ten different huts were randomly selected for entomological surveillance throughout the year. CDC light trap collections were ...

Plasmodium species mixed infections in two areas of Manhiça district, Mozambique

We compared the distribution patterns of individual Plasmodium species and mixed-species infections in two geographically close endemic areas, but showing environmental differences. Comparisons concerned circulating Plasmodium infections in both human and mosquito vector populations in the dry and wet se...

Malaria in pregnancy in rural Mozambique: the role of parity, submicroscopic and multiple Plasmodium falciparum infections

Trop. med. int. health; 7 (1), 2002
Background: Falciparum malaria affects pregnant women, especially primigravidae, but before malaria control programmes targeted to them can be designed, a description of the frequency and parity pattern of the infection is needed. There is little information on the frequency and effect of submicroscopic ...

Placental pathology in malaria: A histological, immunohistochemical, and quantitative study*

Hum. pathol; 31 (1), 2000
Para caracterizar as alterações histológicas nas placentas da malária e sua relação com a paridade e parasitemias maternas e medulares, realizamos um estudo histológico em 1.179 placentas de Ifakara, na Tanzânia, uma área com transmissão intensa e perene da malária. Estudos imuno-histoquímico...
