The burden of malaria and malnutrition among children less than 14 years of age in a rural village of Cameroon

Malaria and malnutrition are a major health burden in developing countries with infants and children being the most vulnerable groups. The extent of the burden of malaria and malnutrition was investigated in 339 children ≤14years residing in the village of Muea located in the South West Province of Cameroon. Malaria parasitaemia was determined microscopically from Giemsa stained thick blood films. Nutritional status was determined using age and the anthropometric parameters of weight and height. Height-for-age (HAZ), weight-for-age (WAZ) and weight-forheight (WHZ) Z scores were computed based on the National Centre for Health Statistics (NCHS)/World Health Organisation growth reference curves. Anaemia was assessed by measuring haemoglobin (Hb) concentration while plasma iron levels were determined by spectrophotometric assays. The prevalence of malaria in the study population was 96.2% (326/339) with a majority (68.4%) having asymptomatic disease. The geometric mean parasite density (GMPD) was 744.37 ± 89396.11 (parasitaemia range 40-153190 parasites/μL blood). The mean Hb concentration was 9.29 ± 1.8g/dL (range 4-14.1g/dL) and anaemia (H

The mean Hb concentration was 9.29 ± 1.8g/dL (range 4-14.1g/dL) and anaemia (Hb<11g/dL) was diagnosed in 81.4% of the children, a majority of whom had microcytic anaemia. A negative correlation was observed between parasite density and haemoglobin concentration (r = -0.14). The mean plasma iron level was 53.64 ± 32.87µL/dl (range 1.8-159) with 58.7% (199/339) of the children diagnosed as iron deficient (plasma iron concentrations <50µg/dL). A negative correlation was observed between plasma iron values and malaria parasitaemia (r = -0.031). The prevalence of malnutrition was 58.1% (197/339). Of the 197 malnourished children, 23.6% were wasted (< -2 SD weight-for-height Z- score), 26.5% underweight (< - 2 SD weight-for-age Z score) and 49.9% stunted (< - 2 SD height-for-age Z score). There was a negative correlation between nutritional status and malaria parasitaemia (r =-0.034). The findings from this study are strongly suggestive that falciparum malaria and malnutrition exist in children residing in Muea and constitute a major health problem which needs to be immediately addressed to reduce morbidity and mortality

THE BURDEN OF MALARIA AND MALNUTRITION AMONG CHILDREN LESS THAN 14 YEARS OF AGE IN A RURAL VILLAGE OF CAMEROON

ABSTRACT Malaria and malnutrition are a major health burden in developing countries with infants and children being the most vulnerable groups. The extent of the burden of malaria and malnutrition was investigated in 339 children ≤14years residing in the village of Muea located in the South West Province of Cameroon. Malaria parasitaemia was determined microscopically from Giemsa stained thick blood films. Nutritional status was determined using age and the anthropometric parameters of weight and height. Height-for-age (HAZ), weight-for-age (WAZ) and weight-forheight (WHZ) Z scores were computed based on the National Centre for Health Statistics (NCHS)/World Health Organisation growth reference curves. Anaemia was assessed by measuring haemoglobin (Hb) concentration while plasma iron levels were determined by spectrophotometric assays.

A negative correlation was observed between parasite density and haemoglobin concentration (r = -0.14).

Serum Biomarker Concentrations upon Admission in Acute Traumatic Brain Injury: Associations with TBI Severity, <i>Toxoplasma gondii</i> Infection, and Outcome in a Referral Hospital Setting in Cameroon

Despite the available literature on traumatic brain injury (TBI) biomarkers elsewhere, data are limited or non-existent in sub-Saharan Africa (SSA). The aim of the study was to analyse associations in acute TBI between the admission serum biomarker concentrations and TBI severity, CT-scan findings, and outcome, as well as to explore the influence of concurrent Toxoplasma gondii infection. The concentrations of serum biomarkers (GFAP, NFL Tau, UCH-L1, and S100B) were measured and Toxoplasma gondii were detected in the samples obtained p = 0.01). The GFAP values significantly increased (p = 0.026) in those with an unfavourable outcome. The Tau levels were higher in those who died (p = 0.017). GFAP and NFL were sensitive to CT-scan pathology (p values of 0.004 and 0.002, respectively). The S100B levels were higher (p Toxoplasma gondii. In conclusion, NFL was found to be sensitive to TBI severity, while NFL and GFAP were predictive of CT intracranial abnormalities. Increased levels of GFAP and Tau were associated with poorer outcomes 6 months after TBI, and the S100B levels were significantly affected by concurrent T. gondii infection in TBI patients compared with the seronegative patients
