Characterization of serological responses to Plasmodium falciparum (Pf) is of interest to understand disease burden and transmission dynamics; however, their interpretation is challenging. Dried blood spots from 30,815 participants aged 6 months to 15 years from the 2018 Nigeria HIV/AIDS Indicator and Impact Survey were analyzed by multiplex bead-b...
Background
Plasmodium falciparum malaria is a leading cause of child mortality in Nigeria. Neonates are born with maternal antibodies from placental transfer which may protect against malaria infection in the first months of life. The IgG dynamics of the transition from passively transferred antimalarial antibodies to actively acquired IgG from nat...
The balance of lifelong learning with assessment for continued certification is a challenge faced by healthcare professions. The value of single-point-in-time assessments has been questioned, and a shift to longitudinal assessments (LA) has been undertaken to assess lifelong learning over-time. This scoping review was conducted to inform healthcare...
Plasmodium falciparum (Pf) is the dominant malaria parasite in Nigeria though P. vivax (Pv), P. ovale (Po), and P. malariae (Pm) are also endemic. Blood samples (n = 31,234) were collected from children aged 0-14 years during a 2018 nationwide HIV survey and assayed for Plasmodium antigenemia, Plasmodium DNA, and IgG against Plasmodium MSP1-19 anti...
Poor management of health care waste poses a serious threat to the health of health care workers, patients and communities. In developing countries, adequate health care waste management (HCWM) is often a challenge. To address this, the Zambian Health Services Improvement Project with HCWM as a component, was implemented in five Zambian provinces (...
The majority of symptomatic malaria in sub-Saharan Africa are caused by Plasmodium falciparum. Infection with Plasmodium ovale is often not recorded and not considered clinically relevant. Here, we describe eight cases of P. ovale infection from three African countries – all of which were misdiagnosed at the presenting health facility.
Racial and ethnic minorities disproportionately suffer the burden of adverse health outcomes in the United States. Increasing the diversity of healthcare providers may help decrease disparities in outcomes. Unfortunately, language barriers may affect performance in nursing school and credentialing examinations. The purpose of this exploratory study...
Background
Rapid diagnostic tests (RDTs) are widely used for malaria diagnosis of both symptomatic and asymptomatic infections. Although RDTs are a reliable and practical diagnostic tool, the sensitivity of histidine-rich protein 2 (HRP2)-based RDTs can be reduced if pfhrp2 or pfhrp3 ( pfhrp2/3 ) gene deletions exist in the Plasmodium falciparum pa...
Background: Malnutrition continues to take the lives of millions of children every year. Children under the age of five years are especially susceptible to high rates of malnutrition and more than half of the deaths in under five children are caused by undernutrition in low- and middle-income countries. Zambia continues to have one of the highest r...
Plasmodium falciparum and Plasmodium vivax are co-endemic in Ethiopia. This study investigated whether mixed infections were missed by microscopy from a 2017 therapeutic efficacy study at two health facilities in Ethiopia. All patients ( N = 304) were initially classified as having single-species P. falciparum ( n = 148 samples) or P. vivax infecti...
Background:
Determining malaria transmission within regions of low, heterogenous prevalence is difficult. A variety of malaria tests exist and range from identification of diagnostic infection to testing for prior exposure. This study describes concordance of multiple malaria tests using data from a 2015 household survey conducted in Ethiopia.

Background
Malnutrition continues to be a major public health challenge in Zambia. To effectively address this, health systems must be well strengthened to deliver an effective continuum of care. This paper examines health systems issues and services in relation to nutritional support to children under five years, in order to identify gaps and prop...
