Parallel Increase in Childhood Anorexia Nervosa and Early Puberty During the COVID‐19 Pandemic

International Journal of Eating Disorders, Volume 59, Issue 1, Page 81-89, January 2026.
ABSTRACT Objective During the COVID‐19 pandemic, an increase in anorexia nervosa (AN), specifically childhood AN, as well as in central precocious puberty (CPP) and early‐onset puberty (EOP), was reported. The aim of this study was to explore whether there was a population‐level association between increases in both disorders and to discuss possible ...

Longitudinal follow-up of bone density and body composition in children with precocious or early puberty before, during and after cessation of GnRH agonist therapy [PDF]

, 2002
We studied bone mineral density (BMD), bone metabolism, and body composition in 47 children with central precocious puberty (n = 36) or early puberty (n = 11) before, during, and after cessation of GnRH agonist.

Protective Roles of Prebiotics and Probiotics Against Environmental Pollutant‐Induced Toxicities: A Systematic Review of Animal Studies

Molecular Nutrition &Food Research, Volume 70, Issue 1, January 2026.
Pollutant‐induced epithelial damage also leads to a cascade of harmful effects, including reduced mucus secretion, decreased luminal pH, and enhanced absorption of toxins. These changes contribute to oxidative stress (↑ malondialdehyde (MDA); ↓ superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), glutathione peroxidase (GPx), and heightened ...

Expanding the Genetic and Phenotypic Spectrum of POLRMT‐Related Mitochondrial Disease

Clinical Genetics, Volume 109, Issue 1, Page 167-175, January 2026.
We identified potentially damaging monoallelic and biallelic POLRMT variants in affected individuals from six unrelated families, thus extending both the clinical and genetic phenotypes of POLRMT‐related mitochondrial disease. ABSTRACT Mitochondrial diseases are a complex group of conditions exhibiting significant phenotypic and genetic heterogeneity ...

Diagnostic Yield and Genotype–Phenotype Correlations of Clinical Exome Sequencing in Hereditary Spastic Paraparesis: Experience From Eastern Spain

European Journal of Neurology, Volume 33, Issue 1, January 2026.
Clinical exome sequencing (CES) was performed on 108 Spanish patients with suspected hereditary spastic paraparesis (HSP), using a virtual 129‐gene panel and HPO‐based variant filtering. A molecular diagnosis was achieved in 53% of cases, with 21 causative genes identified (8 novel variants), SPAST (AD) and SPG7 (AR) being the most frequent genetic ...
