We describe a successful perioperative management of a case of 38-year-old male, presented with chronic jaundice with severe mitral stenosis and moderate tricuspid regurgitation; upon evaluation, he was found to have severe glucose-6-phosphate dehydrogenase (G6PD) deficiency. Usually, patients deficient in G6PD exhibit increased hemolysis and therefore increased need for blood transfusion after cardiac surgery as well as impaired oxygenation in the postoperative period leading to prolonged ventilation. On reperfusion after a period of ischemia, the antioxidant system recruits all of its components in an attempt to neutralize the overwhelming oxidative stress of free radicals, as the free radical scavenging system is deficient in these patients, the chances of free-radical-induced injury is more. Our patient underwent mitral valve replacement and tricuspid annuloplasty under cardiopulmonary bypass with necessary precautions to reduce the formation of free radicals. Treatment was targeted toward the prevention of free radical injury in the G6PD-deficient patient. He had an uneventful intraoperative and postoperative course.

Background: Plasmodium vivax forms dormant liver stages (hypnozoites) that can reactivate weeks to months after primary infection. Radical cure requires a combination of antimalarial drugs to kill both the blood-stage and liver-stage parasites. Hypnozoiticidal efficacy of the liver-stage drugs primaquine and tafenoquine cannot be estimated directly because hypnozoites are undetectable.

Background: As social media continue to grow as popular and convenient tools for acquiring and disseminating health information, the need to investigate its utilization by laypersons encountering common medical issues becomes increasingly essential.
Objectives: This study aimed to analyze the content posted in Facebook groups for Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency and how these engage the members of the group.
Methods: This study employed an inductive content analysis of user-posted content in both public and private Facebook groups catering specifically to G6PD deficiency.

Background: Daily primaquine-induced hemolysis is a common cause of complications during Plasmodium vivax malaria treatment in individuals with glucose 6-phosphate dehydrogenase deficiency (G6PDd). Alternative regimens balancing safety and efficacy are needed.
Methods: G6PDd participants with P.

Loss of dopaminergic neurons in Parkinson's disease (PD) is preceded by loss of synaptic dopamine (DA) and accumulation of proteinaceous aggregates. Linking these deficits is critical to restoring DA signaling in PD. Using murine and human pluripotent stem cell (hPSC) models of PD coupled with human postmortem tissue, we show that accumulation of α-syn micro-aggregates impairs metabolic flux through the pentose phosphate pathway (PPP).

Unlabelled: Newborn screening (NBS) represents an important public health measure for the early detection of specified disorders; such screening can prevent disability and death, not only from metabolic disorders but also from endocrine, hematologic, immune, and cardiac disorders. Screening for critical congenital conditions affecting newborns' health is a great challenge, especially in developing countries such as Morocco, where NBS program infrastructure is lacking. In addition, the consanguinity rate is high in Morocco.
