This multicenter study delves into the prevalence, etiology, and impact of hearing loss among pediatric populations in rural Sub-Saharan Africa over recent decades. Drawing on a diverse array of healthcare facilities, the research incorporates a comprehensive methodology, including diagnostic tools, genetic testing, and interviews, to unravel the complexities of this often-overlooked health concern. The findings reveal a substantial prevalence of pediatric hearing loss, with infants and...

Pregnant radiographers require more stringent occupational safety monitoring through fetal dosimetry because of the sensitivity of their fetuses’ cells to radiation. This study aims to describe fetal dosimetry among pregnant radiographers as regards access, usage, and training. Quantitative data were collected using an electronic national survey. The study collected 89 responses from pregnant and previously pregnant radiographers in South Africa between January 2021 and April 2021. The...

On Sep 8, 2023, a 6·8-magnitude earthquake hit the High Atlas Mountains, in the central region of Morocco. It was the most devastating earthquake in the country for decades, resulting in nearly 3000 deaths and thousands more people injured.1Peláez J A Deadly Morocco quake resulted from Africa's ongoing collision with Europe.

Previous studies on the challenges teachers face when teaching science in German, as well as their corresponding coping strategies, feature a significant blind spot because—to our knowledge—they have only been conducted in regions, where German is the majority language. To address this blind spot, the present case study explores the perspectives of a science teacher on the role of German as language of instruction in a context in which German is a minority language. To this end, we conducted...

Abstract Background The relationship between education and cognitive function in later life has been widely studied, yet it remains uncertain whether the association is due to a true protective effect of education or to test‐taking skills developed through formal education. Literacy, as an objective measure of learning, may clarify this relationship, particularly in low‐ and middle‐income countries (LMIC) where the effect of education may be influenced by school attendance and quality. This...

Ethiopia is experiencing considerable impact of climate change and variability in the last five decades. Analyzing climate trends and variability is essential to develop effective adaptation strategies, particularly for countries vulnerable to climate change. This study analyzed trends and variabilities of climate (rainfall, maximum temperature (Tmax), and minimum temperature (Tmin)) at local and regional scales in Ethiopia. The local analysis was carried out considering each meteorological...

Rangelands of arid ecosystems are driven by internal and external environmental controls. Grazing pressure is an important anthropogenic driver, but stochastic environmental events such as rainfall variability and prolonged drought can have profound effects on arid vegetation. We investigated the effect of a prolonged drought and initial high grazing pressure on range condition, perennial vegetation cover, life form cover, vegetation composition and vegetation diversity at five monitoring...

Hypertension is characterized by the persistent elevation of blood pressure (BP) above the normal range or the use of antihypertensive medication. It represents a major global health issue and serves as a significant risk factor for conditions such as stroke, myocardial infarction, vascular disease, and chronic kidney disease. This study aimed to model the longitudinal measurements of diastolic blood pressure and systolic blood pressure in hypertensive patients using a Bayesian approach. The...

Remediation of synthetic dyes found in aqueous environment poses a serious challenge for treatment due to their resistance to chemical and biological degradation. This research study investigated the application of Chitosan-ZnO-Seaweed bio nanocomposite in the remediation of congo red. The novel bionanocomposite was characterised by FTIR, SEM, TEM, EDS and XRD studies. The FTIR spectra and SEM images indicated the adsorption of congo red onto the synthesized bionanocomposite. The batch wise...

The semi-arid central Karoo of South Africa is an important livestock farming region, oftentimes characterized by water scarcity and limited grazing resources. This paper builds on previous research that has predominantly focused on post 19th century Karoo rainfall characteristics. The paper aims to: 1) establish the long-term frequency and longevity of droughts or dry periods; 2) explore spatial hydroclimatic variability across the Karoo during given dry/drought periods; 3) compare the...

The lack of timely, high-resolution data on agricultural production is a major challenge in developing countries where such information can guide the allocation of scarce resources for food security, agricultural investment and other objectives. While much research has suggested that remote sensing can potentially help to address these gaps, few studies have indicated the immediate potential for large-scale estimations over both time and space. In this study we described a machine learning...

The main objective of this research was to assess indigenous knowledge developed in the agro-pastoralism region of Rwanda to cope with climate change. The study was conducted in drought-prone area of Nyagatare and Gatsibo Districts. Four hundred and eighty (480) households of agro-pastoralists were sampled randomly in 40 villages and interviewed. Focus Group Discussion and interviews with key informants were also used for data collection. Data were analysed using SPSS Statistics 28.0.1....

Since the eighties, many pedagogues of the teaching of French as a second language advocate new approaches which change the didactic landscape; among them, are the Communicative Approach and the Competence Approach. In this regard, we wonder if these changes also affected Morocco. In the Communicative Approach, the teaching of a language must have communicative purposes. The Competency-Based Approach focuses on the construction of competencies by practicing in real complex situations. In the...

This study sought to investigate the impact of the Syrian conflict on the educational and behavioral development of students in the city of Homs, as perceived by teachers. The research employed a descriptive analytical approach and gathered data through a questionnaire. The study's sample comprised 130 secondary school teachers from the Directorate of Education in Homs. The findings revealed that, from the perspective of teachers, there exists a moderate effect on students' educational and...

Objectives There is an increasing rate of elevated blood pressure, or hypertension, in children and adolescents worldwide, including Sub-Saharan Africa (SSA). Only a few data on adolescent hypertension in SSA, including Sudan, have been published. The aim of the present study was to investigate the prevalence and associated factors of hypertension among adolescent schoolchildren (within the ages of 10 to 19 years) in Sudan. Design A cross-sectional school-based study was conducted from June...

As an emerging significant public health issue affecting many students globally, school bullying is a threat that should not be disregarded. While several published studies have focused on bullying in developed countries, very little is known about the prevalence and predictors of bullying in Nigeria. This study aimed to determine the prevalence and predictors of bullying in secondary schools in Edo State, Nigeria.A descriptive cross-sectional study was conducted with 621 in-school...
