Exploring the Epigenetic Landscape of Spermatozoa: Impact of Oxidative Stress and Antioxidant Supplementation on DNA Methylation and Hydroxymethylation.

Reproductive success is dependent on gamete integrity, and oxidative stress alters male nuclei, meaning that no DNA repair is possible due to chromatin compaction. The composition of sperm makes it highly sensitive to reactive oxygen species (ROS) but, at the same time, ROS are needed for sperm physiology. Over the past 30 years, much attention has been paid to the consequences of oxidative stress on sperm properties and the protective effects of antioxidant formulations to help fertility.

Optimizing tacrolimus therapeutic drug monitoring in Tunisian kidney transplant recipients: exploring the variability in bioavailability and the correlation between pharmacokinetic parameters.

Objectives: While the existing literature extensively covers the topic of tacrolimus variability, it remains crucial to gather data that are tailored to the Tunisian population. Our primary goal was to assess the variability in tacrolimus bioavailability using the Cp(0)/weight dosage ratio in Tunisian kidney transplant patients. We also aimed to determine the correlations between blood trough level (Cp(0)) and the area under the concentration-time curve (AUC0-12 h) in this cohort.

French-Speaking Network of Pharmacogenetics (RNPGx) Recommendations for Clinical Use of Mavacamten.

Mavacamten, the first drug in the class of β-cardiac myosin modulator, is used for the treatment of patients with hypertrophic cardiomyopathy. This orally administered drug demonstrates wide interpatient variability in pharmacokinetics parameters, due in part to variant CYP2C19 alleles. Individuals who are CYP2C19 poor metabolizers have increased exposure and are at increased risk of reduced cardiac hypercontractility.

Are Healthcare Professionals Adequately Trained for Safe Blood Transfusions? Targeted Training to Bridge Knowledge Gaps.

Introduction: Ensuring optimal blood transfusion practices relies on a robust expertise base that is indispensable across various professional fields. Recognizing this imperative, the current study aims to assess the knowledge levels of healthcare personnel and enhance transfusion quality through targeted continuing training initiatives.

Methods: The preliminary survey was based on an anonymous questionnaire and we used correct response rate (CRR) as the main parameter evaluating the baseline level of knowledge.

Factors influencing valproic acid trough levels in epileptic children.

Objective: In this study, we aimed to assess main factors influencing the Valproic Acid (V.Acid) plasma trough levels (C0) and to determine their degree of influence on V.Acid C0 in children with epilepsy who had Therapeutic Drug Monitoring (TDM).
