This study investigated the impacts of asbestos wastes on soils in Emene-Enugu, southeastern Nigeria, generated by the activities of a major asbestos products manufacturing company in southeastern Nigeria. The methods of investigation included vertical electrical sounding (VES), 2-D horizontal resistivity profiling (HRP), induced polarization (IP) survey, chemical analysis of plant tissues and standard penetration tests of soil samples. The 2-D HRP and IP identified six closed waste pits alongside the two active pits. The VES revealed four geoelectrical layers in the area: from bottom to top; the inferred lithologies included dark shale, clay, gravel and recent sands. The geochemical data results revealed that Cd concentration of the soils of the waste pits is above the contaminated land exposure assessment soil guideline value for residential and allotment land uses. The geochemical pollution indices classified the soils as "unpolluted" to "extremely polluted". Bioconcentration factor of Pb in plant tissues was found to be above recommended limits of 0.045. The geotechnical parameters indices revealed that the soils varied from "very soft" to "stiff" and "very loose" to "medium". Soils of the active pits have very low strength and bearing capacity while closed pits have high strength and bearing capacity. It may be safe, therefore, to conclude that as the wastes are completely turned into soils, they will assume geotechnical properties similar to those of natural soils.

Multidimensional Poverty due to COVID-19 in Southeast Nigeria: Exploring the Roles of Education, Marital and Employment Status.
Int J Health Plann Manage
January 2025
Department of Art Education, University of Nigeria, Nsukka, Nigeria.
Poverty as a phenomenon is multidimensional, and its incidence and causes constitute constant debate in the literature of the phenomenon. A crisis such as the Coronavirus Disease 2019 (COVID-19) and the resultant lockdowns may increase poverty prevalence among citizens and, particularly, certain demographic characteristics in Nigeria. Hence, this study's general objectives were to interrogate the incidence of multidimensional poverty due to the COVID-19 pandemic in the South-eastern States of Nigeria, using the roles of educational level, marital status, and employment status of citizens as predictors.

Background: There are reports of a high prevalence of maternal peripheral and placental malarial parasitaemia (MP) in southeastern Nigeria following the two-dose regimen of sulphadoxine-pyrimethamine (SP) for intermittent preventive treatment (IPT) of malaria in pregnancy.
Objective: To compare the effectiveness of monthly versus two-dose regimens of SP for IPT of malaria in pregnancy in Enugu, south-eastern Nigeria.
Methods: A randomized controlled trial involving antenatal clinic attendees at the University of Nigeria Teaching Hospital (UNTH), Ituku-Ozalla, Enugu, Nigeria.

Article Synopsis
- There is a significant risk of reinforcing existing health inequalities in AI health technologies due to biases, primarily stemming from the datasets used.
- The STANDING Together recommendations focus on transparency in health datasets and proactive evaluation of their impacts on different population groups, informed by a comprehensive research process with over 350 global contributors.
- The 29 recommendations are divided into guidance for documenting health datasets and strategies for using them, aiming to identify and reduce algorithmic biases while promoting awareness of the inherent limitations in all datasets.
Descriptive epidemiology of Lassa fever, its trend, seasonality, and mortality predictors in Ebonyi State, South- East, Nigeria, 2018-2022.

Department of Epidemiology and Medical Statistics, Faculty of Public Health, College of Medicine, University of Ibadan, Ibadan, Nigeria.
Background: Nigeria is an epicenter for Lassa fever. Ebonyi state is located in the South-Eastern region of Nigeria where a high burden of Lassa fever has been reported. Therefore, this study was designed to assess the epidemiology of Lassa fever, its seasonality, trend, and mortality predictors in Ebonyi state, South-East, Nigeria.

The professional identity of scientists has historically been cultivated to value research over teaching, which can undermine initiatives that aim to reform science education. Course-Based Research Experiences (CRE) and the inclusive Research and Education Communities (iREC) are two successful and impactful reform efforts that integrate research and teaching. The aim of this study is to explicate the professional identity of instructors who implement a CRE within an established iREC and to explore how this identity contributes to the success of these programs.
