Randomized Controlled Trial
Acute intake of fructooligosaccharide and partially hydrolyzed guar gum on gastrointestinal transit: A randomized crossover clinical trial.
Dietary fibers, such as fructooligosaccharide (FOS) and partially hydrolyzed guar gum (PHGG) have several gastrointestinal functions. The aims of this study were to evaluate the effect of acute ingestion of FOS and PHGG on the percentage of gastric emptying and small intestinal transit and to evaluate the effect of these dietary fibers on the levels of intestinal hormones-active glucagon-like peptide-1, pancreatic polypeptide, and gastric inhibitory peptide-and their effect on feelings of hunger and satiety and the desire to eat. ⋯ The acute intake of FOS increased gastric emptying, whereas both FOS and PHGG reduced small intestine transit without altering the levels of intestinal hormones, hunger feelings and satiety, or the desire to eat.

The association between caffeine consumption and mortality in different weight statuses is unclear. This study aimed to explore the effects of caffeine consumption on mortality in different weight statuses. ⋯ The present study suggests that moderate caffeine intake is associated with a lower risk of all-cause mortality in a large study of U.S. adults, especially among those who are overweight. Overweight individuals were more likely to benefit from moderate caffeine intake.

Observational Study
Muscle changes on muscle ultrasound and adverse outcomes in acute hospitalized older adults.
Muscle ultrasound is a non-invasive technique that enables identification of the quantity and quality of muscle tissue. It has been used not only for diagnosis of sarcopenia but also for prediction of outcomes in clinical practice. There is now increasing awareness that muscle changes detected during acute hospitalization indicate acute sarcopenia leading to worse outcomes. However, to our knowledge, few studies have investigated this in hospitalized older adults. The aim of this study was to determine whether muscle changes on muscle ultrasound can predict poor outcomes in acute hospitalized older adults. ⋯ Acute muscle changes on muscle ultrasound were not associated with mortality, ADL decline, or hospital-associated complications in acute hospitalized older adults. More research in various settings is needed to clarify the value of muscle ultrasound in clinical practice.
