Randomized Controlled Trial
Effect of simultaneous supplementation of vitamin A and iron on diarrheal and respiratory tract infection in preschool children in Chengdu City, China.
The goal of this study was to investigate whether vitamin A combined with iron supplementation for preschool children resulted in improved changes in children's infectious morbidity. ⋯ The beneficial affects on infectious morbidity over 6 mo, highlight the potential of vitamin A plus an iron supplement for preschool-aged children.

Randomized Controlled Trial
The influence of consuming an egg or an egg-yolk buttermilk drink for 12 wk on serum lipids, inflammation, and liver function markers in human volunteers.
Dietary cholesterol elevates serum total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) concentrations modestly. There are indications that the cholesterol-raising effect depends on the food matrix, that is, sphingolipids and lactic acid bacteria are suggested to influence cholesterol metabolism. Traditional buttermilk is rich in both sphingolipids and lactic acid bacteria. Therefore, the aim of this study was to evaluate whether effects on cholesterol metabolism depend on food matrix (e.g., cholesterol provided as egg [yolk] or incorporated into traditionally prepared buttermilk drink). ⋯ Daily egg consumption for 12 wk increases serum TC and LDL-C concentrations in women but not markers for inflammation, endothelial activity, and liver function. Interestingly, the rise in serum LDL-C concentrations is less pronounced when egg yolk is incorporated into a buttermilk drink, indeed suggesting that fractions in the buttermilk might influence dietary cholesterol absorption.

Randomized Controlled Trial
Perioperative synbiotic therapy in elderly patients undergoing gastroenterological surgery: a prospective, randomized control trial.
Enteral administration of synbiotics has been reported to be beneficial during various types of surgery, but its clinical value in elderly surgical patients remains unclear. The aim of this study was to quantitatively evaluate the changes in gut microbiota and environment induced by perioperative synbiotic therapy, and to investigate whether it is possible to reduce infectious complications in elderly patients undergoing gastroenterological surgery. ⋯ Synbiotic therapy improved the intestinal microbial environment, and might decrease the incidence of infectious complications in elderly surgical patients.

Randomized Controlled Trial
Effects of creatine supplementation on oxidative stress and inflammatory markers after repeated-sprint exercise in humans.
The goal of this study was to evaluate the effects of creatine (Cr) supplementation on oxidative stress and inflammation markers after acute repeated-sprint exercise in humans. ⋯ Cr supplementation inhibited the increase of inflammation markers TNF-α and CRP, but not oxidative stress markers, due to acute exercise.

Randomized Controlled Trial
Metabolic effects of aloe vera gel complex in obese prediabetes and early non-treated diabetic patients: randomized controlled trial.
The metabolic effects of an aloe vera gel complex (Aloe QDM complex) on people with prediabetes or early diabetes mellitus (DM) are unknown. The goal of this study was to determine the effects of Aloe QDM complex on body weight, body fat mass (BFM), fasting blood glucose (FBG), fasting serum insulin, and Homeostasis Model of Assessment - Insulin Resistance (HOMA-IR) in obese individuals with prediabetes or early DM who were not on diabetes medications. ⋯ In obese individuals with prediabetes or early untreated DM, Aloe QDM complex reduced body weight, BFM, and insulin resistance.
