Does SARS-CoV-2 Infection Increase Risk of Neuropsychiatric and Related Conditions? Findings from Difference-in-Differences Analyses.

The COVID-19 pandemic has been associated with increased neuropsychiatric conditions in children and youths, with evidence suggesting that SARS-CoV-2 infection may contribute additional risks beyond pandemic stressors. This study aimed to assess the full spectrum of neuropsychiatric conditions in COVID-19 positive children (ages 5-12) and youths (ages 12-20) compared to a matched COVID-19 negative cohort, accounting for factors influencing infection risk. Using EHR data from 25 institutions in the RECOVER program, we conducted a retrospective analysis of 326,074 COVID-19 positive and 887,314 negative participants matched for risk factors and stratified by age.

Pseudoprecocious puberty and gynaecomastia as presenting features of Peutz-Jeghers syndrome.

A boy in mid-childhood presented with right-sided gynaecomastia, which was excised. He represented and, on review by endocrinology, Tanner staging showed stage 2 left-sided glandular breast tissue and some features of virilisation. His testicular volumes remained prepubertal (3 mL).

The recent landscape of RSV vaccine research.

Respiratory syncytial virus (RSV) causes a significant burden of acute respiratory illness across all ages, particularly for infants and older adults. Infants, especially those born prematurely or with underlying health conditions, face a high risk of severe RSV-related lower respiratory tract infections (LRTIs). Globally, RSV contributes to millions of LRTI cases annually, with a disproportionate burden in low- and middle-income countries (LMICs).
