Iodine Linked With Men’s Testosterone Levels
Lower iodine concentrations in the urine was independently associated with higher testosterone levels, a cross-sectional study found. Looking at nearly 3,000 U.S. men, those with lower urinary iodine concentrations had significantly higher total testosterone levels than men with either normal or high iodine levels (β -0.028, 95% CI -0.049 to -0.006, P=0.01), Arcangelo Barbonetti, PhD, […]
Reassuring Findings on Bivalent COVID Booster in Hemodialysis Patients
Anti-spike IgG concentrations against BA.4/5 significantly increased in patients with end-stage renal disease (ESRD) following a bivalent booster, particularly in those without a prior Omicron infection, a case series from Germany found. The study looked at 55 ESRD patients on hemodialysis who had received four prior doses of a monovalent vaccine, including about a third […]
Alzheimer’s Disease Detected in Blood a Decade Before Clinical Symptoms
Blood concentrations of glial fibrillary acidic protein (GFAP), a marker of astrogliosis, were higher about 10 years before symptom onset in an inherited form of Alzheimer’s disease. Three plasma biomarkers — phosphorylated tau (p-tau181), neurofilament light chain (NfL), and GFAP — were higher in mutation carriers than non-carriers in a Swedish cohort of autosomal dominant […]
