Long-Term Body Composition Changes in Women Following Roux-en-Y Gastric Bypass Surgery.
Although most individuals experience successful weight loss following Roux-en-Y gastric bypass (RYGB), weight regain is a concern, the composition of which is not well documented. Our aim was to evaluate changes in body composition and handgrip strength as a measure of functional status in participants from a previous 1-year post-RYGB longitudinal study who had undergone RYGB approximately 9 years prior. ⋯ The continued loss of lean mass associated with decreased handgrip strength occurring with long-term trend toward FM regain post-RYGB is concerning. The loss of LST and functional strength carries particular implications for the aging bariatric population and should be investigated further.

Volume-Based Enteral Nutrition Support Regimen Improves Caloric Delivery but May Not Affect Clinical Outcomes in Critically Ill Patients.
Meeting enteral nutrition goals is an ongoing challenge in the intensive care unit (ICU). Most hospitals use rate-based (RB) protocols for nutrient delivery. Previous studies have found that volume-based (VB) protocols improve delivery of prescribed calories. However, these studies did not assess clinical outcomes. We hypothesize that a VB method will improve the delivery of prescribed calories and lead to improved clinical outcomes. ⋯ VB enteral feeding allows for a significantly greater provision of prescribed calories but may not affect clinical outcomes. A larger sample size is needed for adequate power to corroborate these findings.
