Autosomal dominant CDK13-related disease is characterized by congenital heart defects, dysmorphic facial features, and intellectual developmental disorder (CHDFIDD). Heterozygous pathogenic variants, particularly missense variants in the kinase domain, have previously been described as disease causing. Using the determination of a methylation pattern and comparison with an established episignature, we reveal the first hypomorphic variant in the kinase domain of CDK13, leading to a never before described autosomal recessive form of CHDFIDD in a boy with characteristic features.

Introduction: The link between parent-child separation through child welfare systems and negative health and social outcomes is well documented. In contrast, despite the over-representation of Indigenous children and youth in child welfare systems, the relationship between child welfare system involvement and health and social outcomes among Indigenous populations has not been systematically reviewed. Our objective is to assess whether Indigenous People who have been exposed to a child welfare system personally or intergenerationally (ie, parents and/or grandparents) within Canada, Australia, New Zealand and the USA (CANZUS countries) and the circumpolar region are at an increased risk for negative health and social outcomes compared with other exposed and non-exposed groups.

Clermont Auvergne University, EA 3533, Laboratory of the Metabolic Adaptations to Exercise under Physiological and Pathological Conditions (AME2P), CRNH Auvergne, Clermont-Ferrand, France; International Research Chair Health in Motion, Clermont Auvergne University Foundation, Clermont-Ferrand, France.

Physical activity has been shown to improve various aspects of metabolic health and is frequently applied as an intervention in the management and prevention of overweight/obesity. Chrono-exercise can be studied in relation to time of day and timing in relation to a meal, which encompasses chronology and duration of the temporal interval, but the latter has received limited attention to date. This brief review and meta-analysis investigates whether the timing of a meal subsequent to acute exercise, in children and adolescents with and without overweight/obesity, moderates eating behaviour and appetite.

Monocytic reactive oxygen species-induced T cell apoptosis impairs cellular immune response to SARS-CoV-2 mRNA vaccine.

J Allergy Clin Immunol

January 2025

Institute of Human Genetics, UMR9002, CNRS and Montpellier University; Montpellier, France; Montpellier University; Montpellier, France; Immunology Department, University Hospital; Nîmes, France. Electronic address:

Background: We have recently shown that, during acute severe COVID-19, SARS-CoV-2 spike protein (S) induces a cascade of events resulting in T cell apoptosis. Indeed, by neutralizing the protease activity of its receptor, ACE2, S induces an increase in circulating Angiotensin II (AngII), resulting in monocytic release of reactive oxygen species (ROS) and programmed T cell death.

Objective: Here, we tested whether SARS-CoV-2 mRNA vaccines, known to cause the circulation of the vaccine antigen, S-protein receptor binding domain (RBD), might trigger the same cascade.

January 2025

Faculty of Pharmacy and Pharmaceutical Sciences, Monash University, Australia. Electronic address:

Both educators and graduates have expressed concern about a perceived pharmacology knowledge gap that includes difficulty applying fundamental principles to clinical and research problems. Consequently, we sought to determine the extent to which current students can explain the meaning of, and appropriately apply, a subset of core concepts, and to identify any misconceptions arising from the responses. Of the twenty-four pharmacology core concepts arising from the recent international collaboration, four pharmacokinetic concepts were chosen, namely drug bioavailability, drug clearance, volume of distribution, and steady-state concentration.

January 2025

Research Center, Montreal Heart Institute, Department of Medicine, Université de Montréal, Montreal, Canada; Adult Congenital Heart Centre, Montreal Heart Institute, Université de Montréal, Montreal, Canada. Electronic address:

In congenital heart diseases (CHD) of moderate to great complexity involving the right ventricle (RV), the morphologic RV can be exposed to significant stressors across the lifespan either in a biventricular circulation in a sub-pulmonary or sub-aortic position, or as part of a univentricular circulation. These include pressure and/or volume overload, hypoxia, ischemia, and periprocedural surgical stress leading to remodeling, maladaptation, dilation hypertrophy and dysfunction. This review examines the macroscopic remodeling of the RV in various forms of CHD and explores remodeling trajectories, along with the effects of surgeries and residual lesion repair, in tetralogy of Fallot, Ebstein anomaly, congenitally corrected transposition of the great arteries, transposition of the great arteries with atrial switch surgery, and single ventricle palliated by Fontan.
