Brief Summary: This multicenter, international, retrospective study evaluated fertility potential and gonadal function in 326 adolescent and young adult cancer survivors. Risk factors for impairment included hematopoietic stem cell transplantation (HCT) conditioning regimen (myeloablative conditioning, MAC vs reduced-intensity conditioning, RIC).The prevalence of gonadal hormone failure in females was 55.3% (defined as FSH >30 mIU/mL with an estradio...

In Brief This phase 3 trial including 966 adults with biopsy-confirmed non-alcoholic steatohepatitis (NASH) with fibrosis were randomly assigned (1:1:1 ratio) to once-daily resmetirom 80 mg or 100 mg or placebo. Resmetirom, both 80 and 100 mg daily, were superior to placebo with respect to NASH resolution and improvement in liver fibrosis.NASH resolution occurred more frequently in patients on 80-mg (25.9%) and 100-mg resmetirom (29.9%) than on placebo (...

To read the full abstract: J Am Soc Nephrol. 2017 Aug;28(8):2529-2539The association of hyperinsulinaemic hypoglycaemia (HH) and polycystic kidneys has not been reported before. Here, the authors studied 17 patients from 11 different families and found that all patients had a combination HH and polycystic kidneys. The HH was mild and some patients required diazoxide therapy. In contrast the poly...

Brief Summary: This prospective natural history study examined the timing and positive indicators for reshaping of vertebral fractures (VF) in glucocorticoid (GC)-treated patients with chronic diseases. Complete VF reshaping occurred in 82.3% of patients, with similar frequencies in all diagnosis groups (leukemia, rheumatic disorders and nephrotic syndrome) in a median time of 1.3 years. Likelihood of VF reshaping was positively related to higher lumbar spine bone mineral dens...
