Emerging organic compounds in surface and groundwater reflect the urban dynamics in sub-Saharan cities.

Rapid and uncontrolled urbanization in sub-Saharan Africa has led to an increased production and expansion of synthetic chemicals, resulting in significant pollution of the aquatic environments, particularly by Emerging Organic Contaminants (EOCs). Due to the low income of the population in this region, there is often a lack of control over water and fishery resources prior to consumption. Therefore, the current study aims to use EOCs as markers of water resource quality degradation, and to assess the potential environmental risk of these compounds on some aquatic organisms.

Emerging organic compounds as markers of the degradation of groundwater qualitative and quantitative equilibrium in a context of rapid urban expansion.

With the neo-metamorphosis of the residential landscape worldwide and sluggish sanitation strategies in urban environments, rudimentary on-site sanitation systems remain commonly used, especially in developing countries, despite the risks of groundwater contamination. The effective management of such water resources relies on assessment of the sensitivity of anthropized aquifers to man-made impact, including groundwater behavioural alteration, in terms of both quality and quantity. Associated with tracking of changes in land use, this study proposes an approach involving emerging organic contaminants (EOCs) as indicators of the alteration of groundwater balance due the exposure of shallow aquifers to the risks of infiltration of untreated wastewater from soak pits.

Prevalence and economic burden of dementia in the Arab world.

Background: The growing prevalence of dementia is a global concern, especially in the Arab world, where updated economic impact data are scarce. Understanding its prevalence and cost is crucial for effective policies and support systems.

Aims: To estimate dementia prevalence and cost in Arab countries for 2021.

Acquired and hereditary bone marrow failure: A mitochondrial perspective.

The disorders known as bone marrow failure syndromes (BMFS) are life-threatening disorders characterized by absence of one or more hematopoietic lineages in the peripheral blood. Myelodysplastic syndromes (MDS) are now considered BMF disorders with associated cellular dysplasia. BMFs and MDS are caused by decreased fitness of hematopoietic stem cells (HSC) and poor hematopoiesis.

The Effect of Dietary Intake of Vitamin D on Gestational Diabetes Mellitus.

Diabetes mellitus (DM) is a growing health issue that has been reaching epidemic proportions in the recent years. Low intake of some nutrients like vitamin D may increase the risk of gestational diabetes mellitus (GDM). This study was to investigate the association between the dietary intake of Vitamin D and GDM among women in the Eastern Region of Saudi Arabia.
