Background & Aims: No study has yet compared body fat distribution before and after weight restoration in adolescent and adult patients with anorexia nervosa (AN) treated according to the same protocol. The study was set up to measure body fat distribution before and after short-term weight restoration in adolescent and adult patients with AN treated according to the same protocol in a specialist inpatient unit.
Methods: We recruited 33 consecutive adolescent female patients with AN, and 33 controls matched by age and post-treatment BMI centile, as well as 33 adult female patients with AN, and 33 controls matched by age and post-treatment BMI. Dual-energy X-ray absorptiometry (DXA) was used to assess body composition before and after short-term weight restoration (BMI ≥ 18.5 kg/m²).
Results: Compared with controls, both adolescents and adults with AN showed that a greater amount of fat was lost from the extremities than the trunk before weight restoration, and that there was a central adiposity phenotype after short-term weight restoration. There were no significant differences in body fat distribution between adolescents and adults with AN before or after short-term weight restoration.
Conclusions: Adolescent and adult females with AN have similar body fat distribution both before and after short-term weight restoration, and show a central adiposity phenotype after short-term weight restoration. The clinical implications of this finding are as yet unknown. Clinical Trials Registry- Regional Fat Distribution in Adolescent Girls and Adults with Anorexia Nervosa (ISRCTN73572502).

High molecular weight hyaluronan (HMWH) inhibits hyperalgesia induced by diverse pronociceptive inflammatory mediators and their second messengers, in rats of both sexes. However, the hyperalgesia induced by ligands at 3 pattern recognition receptors, lipopolysaccharide (a toll-like receptor 4 agonist), lipoteichoic acid (a toll-like receptor 2/6 agonist), and nigericin (a NOD-like receptor family, pyrin domain containing 3 activator), and oxaliplatin and paclitaxel chemotherapy-induced peripheral neuropathy are only attenuated in males. After gonadectomy or intrathecal administration of an antisense to G-protein-coupled estrogen receptor 30 (GPER) mRNA, HMWH produces antihyperalgesia in females.

To investigate corticospinal tract (CST) injury and remodeling in patients with basal ganglia intracerebral hemorrhage (ICH) and explore the characterization capabilities of the corresponding parameters. In this prospective study, baseline, scale, and diffusion-weighted imaging (DWI) data were collected from patient cohorts. Participants were stratified into favorable (0-3 points) and unfavorable (4-6 points) prognosis groups, based on Modified Rankin Scale (mRS) after 3-6 months.

Compared with non-carriers, cognitively normal, middle-aged APOE4 carriers have lower cerebral blood flow (CBF) decades before clinical symptoms appear. Early intervention to protect CBF would be critical for APOE4 carriers to mitigate AD progression.

Compared with non-carriers, cognitively normal APOE4 individuals have shown brain atrophy and lower cerebral blood flow (CBF) decades before AD pathological and clinical symptoms appear. The goal of the study is to determine if using Sirolimus, an FDA-approved mTOR inhibitor, could restore the brain volumes in structures related to cognitive functions and global CBF (gCBF) for asymptomatic APOE4 carriers compared with non-carriers.
