Effect of oral protein supplementation on nutritional status in hemodialysis patients: A randomized clinical trial.

BACKGROUND This study aimed to evaluate the effect of oral protein supplementation on malnutrition risk, as assessed by the Malnutrition Universal Screening Tool (MUST), in patients undergoing hemodialysis. METHODS In this randomized clinical trial, 52 hemodialysis patients at risk of malnutrition (MUST score >1) were recruited from a single center. The intervention group received 24 g of oral vitamins, minerals and casein protein (V.M. protein) daily for 4 months immediately after dialysis sessions on dialysis days. The control group continued their usual diet without supplementation. All participants received standard dietary counseling. The primary outcome was a change in mean body weight. Secondary outcomes included changes in MUST score, bioimpedance parameters (phase angle, body fat mass, visceral fat area, extracellular water-to-total body water ratio [ECW/TBW]), and laboratory markers. Bonferroni correction was applied for multiple comparisons. RESULTS The mean age of participants was 59.10 ± 14.09 years, and 69.57% were male. A significant improvement in MUST score was observed within the intervention group but not in the control group. Changes in body weight and other secondary outcomes were assessed, with trends suggesting improvement in body composition parameters. CONCLUSION Oral protein supplementation may improve nutritional status and reduce malnutrition risk in patients undergoing hemodialysis, with potential benefits for body composition and overall health.

Preoperative nutrition in colorectal cancer surgery: mini review

In colorectal cancer patients, malnutrition, sarcopenia, and even cachexia are highly prevalent (24–65%); those patients who undergo surgery with a compromised nutritional status tend to have more complications (OR: 1.84; 1.35–2.48). Therefore, proper nutritional management before surgery is essential. The principal therapeutic option for patients with colorectal cancer is surgery; in this way, these patients are vulnerable to a worse prognosis if a preoperative nutritional intervention is not considered. An individualized, well-designed nutrition care plan, as part of a multimodal therapeutic approach, that promotes adequate energy and protein intake to counteract catabolism and preserve muscle mass can help improve postoperative outcomes. Other strategies that may be useful for patients undergoing colorectal cancer surgery are immunonutrition and micronutrient supplementation. The combined use of certain immunonutrients, such as polyunsaturated fatty acids, branched-chain amino acids, arginine, glutamine, and nucleotides, has been suggested in some studies to help reduce surgery-related complications and infections, promote better wound healing, and shorten hospital stay after colorectal surgery. Certain micronutrients, such as vitamin C and zinc, can enhance the clinical effects of prior nutritional interventions and promote postoperative recovery. Nevertheless, limitations and mixed results in the current evidence preclude recommending these strategies in routine clinical practice. An individualized approach for each patient should be considered to improve surgical outcomes through nutrition.

Early oral nutritional supplementation combined with graded functional exercise for postoperative recovery in patients undergoing pancreaticoduodenectomy.

Early initiation of ONS combined with graded functional exercise following PD in patients with pancreatic neoplasms was associated with improved postoperative nutritional status, attenuation of skeletal muscle loss, and enhanced recovery of gastrointestinal and physical function, thereby supporting subsequent treatment.
