Nutritional management during critical illness in those with previous obesity surgery.

Purpose Of Review: The prevalence of overweight and obesity in our society is a pressing concern that has demanded immediate attention. Traditional treatments have proven ineffective for many individuals, leading to a surge in bariatric surgery as a last resort. While the rate of early and late postoperative complications may be low, when they occur, they place these patients at higher risk of requiring intensive care treatment.

Low phase angle in critically ill older patients is associated with late mortality: A prospective study.

Objectives: The aim of this study was to ascertain the accuracy of phase angle (PhA) as a predictor of mortality during intensive care unit (ICU) stay (M) and at 28 (M) and 60 d (M) after ICU admission among patients aged >60 y.

Methods: Patients aged >60 y who were under mechanical ventilation (MV) ≥48 h were included once they were hemodynamically stable. PhA was measured by single-frequency bioelectrical impedance analysis up to 48 h after admission.
