Efficacy of therapeutic plasma exchange in patients with severe COVID-19: A systematic review and meta-analysis.

We conducted this systematic review and meta-analysis to evaluate the existing evidence and to quantitatively synthesise evidence on the impact of therapeutic plasma exchange (TPE) on severe COVID-19 patients. This systematic review and meta-analysis protocol was prospectively registered on PROSPERO (CRD42022316331). We systemically searched six electronic databases (PubMed, Scopus, Web of Science, ScienceDirect, clinicaltrial.

The potential role of vitamin E in patients with glucose-6-phosphate dehydrogenase deficiency: A systematic review and meta-analysis.

Background: As an antioxidant, vitamin E (VitE) may benefit the erythrocytes by protecting glutathione from oxidation by free radicals and peroxide-generating processes.

Methods: We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement guidelines when reporting this systematic review. We searched 6 electronic databases (PubMed, Scopus, Web of Science, and Cochrane Library) until May 8, 2022.

Prevalence and risk assessment of microplastics in the Nile Delta estuaries: "The Plastic Nile" revisited.

Recent research is directed toward studying plastic pollution in rivers, and estuaries due to the importance of freshwater bodies in all aspects of life. The river deltas and estuaries are interesting for studying the flux of plastics into the oceans. The Nile River has been identified as a hot spot of plastic litter flux in the eastern Mediterranean basin.

T-Natural Killers and Interferon Gamma/Interleukin 4 in Augmentation of Infection in Foot Ulcer in Type 2 Diabetes.

Background: The link between immune system and type 2 diabetes mellitus (T2DM) pathogenesis attracted attention to demonstrate the role of immune cells and their secreted cytokines in T2DM development and its subsequent foot complications.

Objective: To investigate the relation between T Natural killer cell (TNK) %, Interleukin 4 (IL4) and Interferon gamma (IFN-γ) and diabetic foot infection (DFI) development in patients with diabetic foot ulcer (DFU).

Patients And Methods: Ninety patients with diabetes were included in this work, divided as T2DM group (n=30), DFU group (n=30), and DFI group (n=30).

Geochemical and hydrogeological factors influencing high levels of radium contamination in groundwater in arid regions.

One of the most challenging environmental issues in arid regions is radionuclide groundwater contamination; typically, radionuclide sources, mobility, and spatial distributions are not well understood. The main objectives of this study are to investigate the groundwater hydrochemistry and identify the factors governing the radium occurrences and mobility. Groundwater samples were collected from shallow unconfined zone and deep confined Saq sandstone aquifer in the Hail area, Saudi Arabia.
