Owl monkeys (Aotus nancymaae) are New World NHP that serve an important role in vaccine development and as a model for human disease conditions such as malaria. Despite the past contributions of this animal model, limited information is available about the phenotype and functional properties of peripheral blood lymphocytes in reference to sex and age. Using a panel of human antibodies and a set of standardized human immune assays, we identified and characterized various peripheral blood lymphocyte subsets, evaluated the immune functions of T cells, and analyzed cytokines relative to sex and age in healthy owl monkeys...

OBJECTIVES: Limited data are available on sepsis in low-resource settings, particularly outside of urban referral centers. We conducted a prospective observational single-center cohort study in May 2013 to assess the presentation, management and outcomes of adult and pediatric patients admitted with sepsis to a community hospital in rural Uganda. METHODS: We consecutively screened all patients admitted to medical wards who met sepsis criteria. We evaluated eligible patients within 24 hours of presentation and 24-48 hours after admission, and followed them until hospital discharge...

Cerebral malaria (CM), a complication of malaria infection, is the cause of the majority of malaria-associated deaths in African children. The standard clinical case definition for CM misclassifies ~25% of patients, but when malarial retinopathy (MR) is added to the clinical case definition, the specificity improves from 61% to 95%. Ocular fundoscopy requires expensive equipment and technical expertise not often available in malaria endemic settings, so we developed an automated software system to analyze retinal color images for MR lesions: retinal whitening, vessel discoloration, and white-centered hemorrhages...

BACKGROUND: Severe acute malnutrition (SAM) is a major health problem, and the cause of more than half of childhood deaths in children less than 5 years in developing countries. Globally, 20 million children under 5 years of age are severely malnourished according to the World Health Organization (WHO). In Cameroon, the prevalence of SAM remains high and estimated at 1.9% in 2011 and 1.3% in 2014. The aim of this study was to determine the epidemiology, clinical aspects and outcome of SAM at the Yaounde Gynaeco-Obstetric and Pediatric Hospital (YGOPH)...

Liberia is a low-income country in West Africa that has faced significant challenges, including a civil war and the recent Ebola epidemic. Little data exists on the more current post-war and pre-Ebola trends of child health in Liberia in the rural setting. This study is a retrospective chart review of pediatric mortality in 2013 at a rural tertiary care center in Liberia, 10 years post-war. From January 2013 to December 2013, there were 50 pediatric deaths, or 5.4% of the 920 total pediatric admissions. The most common cause of neonatal death was sepsis, and the most common cause of death under five years of age was malaria...

: Endemic Burkitt lymphoma (eBL) is the most common pediatric cancer in malaria-endemic equatorial Africa and nearly always contains Epstein-Barr virus (EBV), unlike sporadic Burkitt Lymphoma (sBL) that occurs with a lower incidence in developed countries. Given these differences and the variable clinical presentation and outcomes, we sought to further understand pathogenesis by investigating transcriptomes using RNA sequencing (RNAseq) from multiple primary eBL tumors compared to sBL tumors...

BACKGROUND: In Bo district, rural Sierra Leone, we assessed the burden of the 2014 Ebola outbreak on under-five consultations at a primary health center and the quality of care for under-15 children at a Médecins Sans Frontières (MSF) referral hospital. METHODS: Retrospective cohort study, comparing a period before (May-October 2013) and during the same period of the Ebola outbreak (2014). Health worker infections occurred at the outbreak peak (October 2014), resulting in hospital closure due to fear of occupational-risk of contracting Ebola...

Rickettsial infections are an underrecognized cause of febrile illness in sub-Saharan Africa. To evaluate the epidemiology and clinical features of rickettsial disease in pediatric patients in Ghana, we screened blood samples from febrile children aged less than 15 years presenting to an outpatient department in Ghana's Ashanti Region for the presence of rickettsial DNA. We detected Rickettsia felis in 7/470 (1.5%) blood samples, using two independent real-time polymerase chain reactions. No other Rickettsia species were found...

BACKGROUND: Malaria rapid diagnostic tests (RDTs) have great potential to improve quality care and rational drug use in malaria-endemic settings although studies have shown common RDT non-compliance. Yet, evidence has largely been derived from limited hospital settings in few countries. This article reviews a PhD thesis that analyzed national surveys from multiple sub-Saharan African countries to generate large-scale evidence of malaria diagnosis practices and its determinants across different contexts...

Congenital malaria, in which infants are directly infected with malaria parasites from their mother prior to or during birth, is a potentially life-threatening condition that occurs at relatively low rates in malaria endemic regions. We report an unusual case of a 23-day-old girl with neonatal Plasmodium vivax malaria, suspected primarily on the basis of positive maternal history that her mother had malaria during her pregnancy and was cured with chloroquine therapy. Infant presented with fever, thrombocytopenia and a significant parasitemia...

Extracorporeal Membrane Oxygenation (ECMO) is widely used in Acute Respiratory Distress Syndrome (ARDS) and myocarditis. Severe vector-mediated diseases may be complicated by ARDS or myocarditis, which are both associated with a high mortality rate. We present six cases of severe dengue, malaria, and acute Chagas disease that were treated with ECMO from September 2007 to September 2015. Patients included two pediatric and four adults (ages 12 to 48). Survival to decannulation was 83% and to discharge was 66%...

In Niger, malaria is a major public health problem, due to the high number of deaths that are attributable to it and because of its heavy weight and socioeconomic status. The objective of this study was to contribute to the inventory of medical practices to rationalize the use of medicines and minimize the resistance phenomenon. This is a prospective study, which took place from May 1 to July 31, 2009, in the pediatric ward of the National Hospital of Lamordé. It concerned children aged from 0 to 14 years hospitalized and having received one or more antimalarial drugs during at least 24 h...

BACKGROUND:  Pediatric acute respiratory distress in tropical settings is very common. Bacterial pneumonia is a major contributor to morbidity and mortality and requires adequate diagnosis for correct treatment. A rapid test that could identify bacterial (vs. other) infections would have great clinical utility. METHODS AND FINDINGS:  We performed RNA-Seq and analyzed the transcriptomes of 68 pediatric patients with well-characterized clinical phenotype to identify transcriptional features associated with each disease class...

Data on the burden and incidence of endemic Burkitt lymphoma (eBL) across Mozambique are scarce. We retrospectively retrieved information on eBL cases from reports of the three main hospitals of Mozambique: Maputo Central Hospital (MCH), Beira Central Hospital (BCH), and Nampula Central Hospital (NCH) between 2004 and 2014. For 2015, we prospectively collected information of new eBL cases attending these hospitals. A total of 512 eBL cases were reported between 2004 and 2015: 153 eBL cases were reported in MCH, 195 in BCH, and 164 in NCH...

BACKGROUND: Malaria is an important cause of death and illness in children worldwide. Most cases of neonatal malaria are misdiagnosed because of the lack of specific symptoms and a general lack of awareness. Nothing much is known in literature about the haematological changes during malaria infection and outcome of disease in neonates. Neonatal malaria is an underdiagnosed entity. So this hospital based observational study aims to assess diagnostic features of neonatal malaria. METHODS: From August 2004 to August 2013, information of all slide positive for malaria cases aged 0 to 28 days admitted to our pediatric hospital was collected and analysed...

Background.  Host responses to infection are critical determinants of disease severity and clinical outcome. The development of tools to risk stratify children with malaria is needed to identify children most likely to benefit from targeted interventions. Methods.  This study investigated the kinetics of candidate biomarkers of mortality associated with endothelial activation and dysfunction (angiopoietin-2 [Ang-2], soluble FMS-like tyrosine kinase-1 [sFlt-1], and soluble intercellular adhesion molecule-1 [sICAM-1]) and inflammation (10 kDa interferon γ-induced protein [CXCL10/IP-10] and soluble triggering receptor expressed on myeloid cells-1 [sTREM-1]) in the context of a randomized, double-blind, placebo-controlled, parallel-arm trial evaluating inhaled nitric oxide versus placebo as adjunctive therapy to parenteral artesunate for severe malaria...

Burkitt lymphoma (BL) is >90% EBV-associated when this pediatric cancer is diagnosed in regions heavily burden by endemic Plasmodium falciparum malaria and thus has been geographically classified as endemic BL. The incidence of endemic BL is 10-fold higher compared to BL diagnosed in non-malarious regions of the world. The other forms of BL have been classified as sporadic BL which contain EBV in ∼30% of cases and immunodeficiency BL which occurs in HIV-infected adults with ∼40% of tumors containing EBV...
