This study aimed to describe the epidemiological, clinical, and paraclinical profiles of patients with severe coma in Tunisian intensive care units (ICUs), and to identify factors associated with progression to brain death (BD) and subsequent organ donation outcomes. A pilot prospective multicenter study was conducted over one year (November 2022 - October 2023) in three Tunisian university hospitals: Sahloul and Farhat Hached (Sousse), and Mohamed Taher Maamouri (Nabeul). All ICU patients with severe coma (i.e.; Glasgow coma scale≤8) requiring invasive mechanical ventilation were included. Patients were followed until BD confirmation or ICU discharge.

This study investigates genetic variations within exon 3 of the <i>QRICH2</i> gene, identifying novel heterozygous variants associated with sperm tail-specific abnormalities and motility impairments. Among 34 individuals diagnosed with asthenozoospermia (ASZ) and 26 individuals with normal sperm parameters (NZ) from Jordan, eight unique heterozygous variants (c.123 G>T, c.133 G>C, c.138A>G, c.170A>C, c.189C>G, c.190T>C, c.195A>T, and c.204A>T) were exclusive to the ASZ group, while four variants (c.136 G>A, c.145A>C, c.179T>G, and c.180T>G) were found only in NZ. These variants were absent from major genetic databases, suggesting their potential novelty, while two variants (c.206C>T and c.189C>T) were linked to known SNP cluster IDs rs73996306 and rs1567790525, respectively.
