An International ASXL3 Natural History Study: Deep Phenotypic Analyses Including Detailed Reports of a Milder Phenotype, Novel Associations, and Clinical Recommendations

American Journal of Medical Genetics Part A, Volume 197, Issue 11, November 2025.
ABSTRACT Natural History Studies can help inform clinician and caregiver expectations, form the basis of management guidelines, and provide a comparator for therapeutic intervention. In rare conditions, where collection of prospective longitudinal data is untimely and impractical, quasi‐natural history data—from multiple individuals of different ages ...

Endocrine disruptors and abnormalities of pubertal development [PDF]

, 2008
Onset and development of puberty is regulated by the neuroendocrine system. Population-based studies worldwide have observed secular trends towards earlier puberty development. These changes are apparently caused by environmental factors such as improved

Bone Mineral Accrual From Adolescence Into Young Adulthood and Peak Bone Mass: A Longitudinal Cohort Study

Health Science Reports, Volume 8, Issue 11, November 2025.
ABSTRACT Background and Aims Understanding bone mass accumulation patterns and factors influencing them during growth is important for preventing osteoporosis later in life. This study investigated longitudinal changes in bone mineral content (BMC), bone mineral density (BMD), and bone mineral apparent density (BMAD) during growth, with the aim of ...

Pediatric Obesity, Volume 20, Issue 11, November 2025.
ABSTRACT Background Childhood obesity interventions often overlook sleep and emotional wellbeing, though research shows both are associated with weight status across childhood. The timing of their co‐development and the most effective point for intervention remain poorly understood. The aim of this study was to examine the trajectories of sleep, weight
