Outcomes of pediatric patients with suspected allergies to COVID-19 vaccines.

Background: Adverse effects following immunizations (AEFIs) can contribute to vaccine hesitancy.

Objective: We evaluated clinical outcomes of AEFIs subsequent to administration of the coronavirus disease 2019 (COVID-19) vaccine at 2 pediatric allergy centers.

Methods: Data on pediatric patients referred for COVID-19 AEFI concerns between March 2021 and October 2022 were reviewed.

Case report: A novel germline loss-of-function mutation in the STAT1 transactivation domain in two Chinese siblings, with the elder sibling presenting with multifocal Calmette-Guerin osteomyelitis.

Signal transducer and activator of transcription 1 (STAT1) gene mutations have broad clinical phenotypes, classified by the inheritance pattern and functional state. Individuals with autosomal dominant STAT1 deficiency are more susceptible to intracellular bacteria, the hallmark of which is Mendelian susceptibility to mycobacterial diseases (MSMDs) that are associated with increased risks of invasive disease by weakly virulent mycobacteria. We report a novel heterozygous missense mutation in exon 23 of the STAT1 gene (NM_007315.

Re-Engagement in Physical Activity Slows the Decline in Older Adults' Well-Being - A Longitudinal Study.

Physical activity is recommended for older adults; however, the benefits of previous active engagement in physical activity that can be sustained after one becomes inactive remain to be determined. This study investigated the longitudinal associations between physical activity engagement patterns and older adults' well-being. This population-based cohort study used data from the China Health and Retirement Longitudinal Study between 2015 and 2020.

Tissue-Specific Ablation of Liver Fatty Acid-Binding Protein Induces a Metabolically Healthy Obese Phenotype in Female Mice.

Background/objectives: Obesity is associated with numerous metabolic complications including insulin resistance, dyslipidemia, and a reduced capacity for physical activity. Whole-body ablation of liver fatty acid-binding protein (LFABP) in mice was shown to alleviate several of these metabolic complications; high fat (HF) fed LFABP knockout (LFABP) mice developed higher fat mass than their wild-type (WT) counterparts but displayed a metabolically healthy obese (MHO) phenotype with normoglycemia, normoinsulinemia, and reduced hepatic steatosis compared with WT. LFABP is expressed in both liver and intestine, thus in the present study, LFABP conditional knockout (cKO) mice were generated to determine the contributions of LFABP specifically within the liver or the intestine to the whole body phenotype of the global knockout.
