Randomized Controlled Trial
Acute effects of time-restricted feeding in low-income women with obesity placed on hypoenergetic diets: Randomized trial.
The aim of this study was to evaluate the acute effects of time-restricted feeding in obese women living in social vulnerability who were placed on diets with the same energy deficit. ⋯ Time-restricted feeding may be considered an alternative strategy for treating obesity in socially vulnerable women.

Approximately 50% to 60% of amyotrophic lateral sclerosis (ALS) is characterized by an increase in metabolic rate. The Harris and Benedict (HB) 1919 formula is the equation mainly used to calculate resting energy expenditure (cREE) compared with measured REE (mREE) by indirect calorimetry (IC), but other formulas are also applied in current practice. The present study aimed to assess mREE in patients with ALS compared with 12 cREE formulas and study the relevant threshold of REE variation to screen patients with a higher evolving risk. ⋯ The increase in metabolic rate is present according to the different cREE formulas used compared with IC. In clinical practice, REE formulas (e.g., HB 1919, HB 1984, or Mifflin) can be used as a reference value compared with IC to screen patients with ALS with an REE variation >20% and a higher evolving risk.

There is a growing interest in identifying alternatives to traditional oligosaccharide-based prebiotic agents owing to their undesirable attributes, such as a lack of microbial growth specificity and limited inherent bioactivity. In addition, a novel concept of second-generation synbiotic agents is currently emerging, which argues that prebiotic agents could be best defined on the basis of their physiological effects or functional capacities in the host rather than their specific microbial targets. ⋯ In the present review, we study evidence pertaining to the prebiotic and synbiotic attributes of polyphenols, as well as their relationship with probiotic bacteria, and discuss their efficacy, suitability, and strategies to develop second-generation synbiotic agents. We provide a perspective that polyphenol-based synbiotic agents are fundamentally superior to the traditional carbohydrate-based synbiotic agents and could therefore offer health benefits of both polyphenols and probiotic agents in a synergistic manner.

Recommended perioperative nutritional interventions may contribute to satisfactory surgical outcomes. Each moment in the course of a surgical pathologic condition may be a window of opportunity for an intervention with a positive impact on postoperative recovery. Based on the idea of accelerating postoperative recovery, the objective of this study was to evaluate the effectiveness of a nutritional intervention with preoperative fasting abbreviation (Enhanced Recovery After Surgery recommendations) on the metabolism of patients undergoing gynecologic surgeries under spinal anesthesia. ⋯ Preoperative fasting abbreviation with liquid containing carbohydrate and protein before gynecologic surgeries may provide metabolic stability with lower variation in insulin resistance than inert solution.

In recent years, home enteral nutrition (HEN) has been adopted as a feasible and safe form of nutrition for patients undergoing esophagectomy. The aim of this study was to compare the effects of 4 wk of HEN with standard enteral nutrition (SEN) on immune function, nutritional status, and survival in patients undergoing esophagectomy. ⋯ Four weeks of HEN is a safe and feasible nutritional strategy to improve immune function and nutritional status after esophagectomy. Although there was no significant difference in survival between the two groups, HEN could still be more effective and beneficial than SEN to patients with defective nutritional and immune status.
