Background Characterizing the parasite dynamics and population structure provides useful information to understand dynamic of transmission better target control interventions. Despite considerable efforts for its control, vivax malaria remains a major health problem in Peru. In this study, we have explored genetics Plasmodium isolates from Iquitos, main city Peruvian Amazon, 25 neighbouring peri-urban as well rural villages along Iquitos-Nauta Road. Methodology/ Results From April December...

Background Outpatient treatment of acute malnutrition is usually centralized in health centers and separated into different programs according to case severity. This complicates detection, care delivery, supply chain management, making it difficult for families access treatment. study assessed the impact treating severe moderate cases same program using a simplified protocol decentralizing outside through community workers (CHWs). Methods A three-armed cluster randomized controlled trial...

Background: the aim of this study is to evaluate effectiveness and coverage a simplified protocol that implemented in health centers (HCs) posts (HPs) for children who are suffering from severe acute malnutrition (SAM) humanitarian context Diffa. Methods: We conducted non-randomized community-controlled trial. The control group received outpatient treatment SAM, without medical complications, at HCs HPs with standard community management (CMAM). Meanwhile, respect intervention group, SAM...

Objective/Background Sickle cell disease (SCD) is a monogenic with highly variable phenotype depending on the amount of fetal hemoglobin (HbF), main modulator. Variation HbF levels among patients genetically regulated. determines both and response to treatment drug used, hydroxyurea. The efforts researchers have focused discovering genetic factors responsible for variation, mainly describing haplotypes β cluster single nucleotide polymorphisms (SNPs) at three different loci: BCL11A,...

Abstract Throughout the past few years, a lively debate emerged about timing and magnitude of human migrations between Iberian Peninsula Maghreb. Several pieces evidence, including archaeological, anthropological, historical, genetic data, have pointed to complex intermingled evolutionary history in western Mediterranean area. To study what extent connections across Strait Gibraltar surrounding areas shaped present-day genomic diversity its populations, we performed screening 2.5 million...

Of the 45.4 million children under five affected by acute malnutrition in world, majority (31.8 million) are moderate (MAM). Its treatment is particularly complex emergency settings such as Diffa region Niger. This study aims to evaluate effectiveness and coverage of a simplified protocol with Community Health Workers (CHWs) providers.This non-randomized controlled trial. The control group (n = 181) received standard currently used country, delivered nursing staff only health centres posts,...

Child acute malnutrition is a global public health problem, affecting 45 million children under 5 years of age. The World Health Organization recommends monitoring weight gain weekly as an indicator the correct treatment. However, simplified protocols that do not record and base diagnosis follow-up in arm circumference at discharge are being tested emergency settings. present study aims to use machine learning techniques predict based on socio-economic characteristics admission for treated...

Sickle cell disease (SCD), despite being a monogenic disease, presents highly variable phenotype that essentially depends on the amount of fetal hemoglobin (HbF), constituting main modulator disease. The variation HbF levels between patients is genetically regulated. determines both and response to treatment with drug used, hydroxyurea. Researchers’ efforts have focused discovering genetic factors responsible for its variation; mainly describing haplotypes β cluster SNPs in three different...
