The aim was to investigate the relationships among lean mass (LM), fat mass (FM), and bone mineral density (BMD) in women stratified by body mass index (BMI) (BMI - normal-weight, overweight, obese) and to determine threshold at which body fat assumes negative relationship with BMD. ⋯ Although LM has strong positive relationship with BMD, FM above 33% in overweight/obese women is negatively related to BMD of most skeletal sites. Therefore, overweight/obesity after certain amount of FM, may not be a protective factor against osteoporosis in females. For clinical practice in women, it is important to maintain LM and keep FM accrual below ~30% body fat to maintain good skeletal health.

Obstructive sleep apnea (OSA) is very frequent and often unrecognized in surgical patients. OSA is associated with perioperative complications. We evaluated the effects of OSA on postoperative complications and hospital outcomes in patients undergoing coronary artery bypass graft (CABG) surgery. ⋯ Obstructive sleep apnea is frequent, but unrecognized among patients undergoing CABG. In these patients, OSA is associated with prolonged intubation duration. Preventing these problems may be possible by early diagnosis and management of OSA in cardiac surgery patients. Further studies with larger sample of patients and longer follow-ups are required in this regard.
