A study of 856 transfeminine adults aged 65+ found they had 39% higher odds of Alzheimer’s disease and related dementias compared to cisgender men, with the association strengthening to a 75% higher odds for those receiving gender-affirming hormone therapy. This suggests dementia diagnosis and management should be a healthcare priority for older transfeminine people, especially those on hormone therapy.

A meta-analysis of 34 studies found that patients with severe aortic stenosis and advanced cardiac damage, particularly right ventricular dysfunction, face significantly higher mortality after a transcatheter aortic valve replacement (TAVI), with a 2.77 times higher risk of death at one year for the most severe stage. This highlights the critical need to assess this extravalvular heart damage before the procedure to better predict patient outcomes and guide care.

An analysis of five patients with systemic lupus erythematosus (SLE) showed that a new dual-targeting CAR-T cell therapy (attacking both BCMA and CD19) led to deeper depletion of harmful immune cells and a greater reversal of disease-related molecular signatures than previous single-target therapies. This exploratory finding points to a potential advantage for achieving a more complete reset of the immune system in autoimmune diseases like lupus.

A case report details a life-threatening metabolic crisis in a breastfed infant, triggered when the mother ate unripe ackee fruit, which contains a toxin that disrupts the body’s ability to burn fat for energy. This case underscores the importance of counseling breastfeeding individuals to avoid unripe ackee, as the toxin can pass through breast milk and cause severe illness, especially in infants with underlying genetic vulnerabilities.

Research using single-cell RNA sequencing on a pediatric lupus patient with a specific genetic mutation (IKZF1 haploinsufficiency) revealed a near-total absence of regulatory B cells and arrested B cell maturation, pinpointing these as key targets of the genetic defect. This detailed molecular mapping informed a successful, personalized treatment with specific drugs, showcasing how advanced genetic analysis can guide precise therapies for complex immune diseases.
