Imaging studies have shown brain abnormalities associated with eating behavior (taste perception, food intake, and food reward), neural connectivity, and cognition related to obesity. The aim of this study was to investigate whether obese individuals have changes in regional cerebral blood flow (rCBF) during fasting and rest using single-photon emission computed tomography (SPECT), and whether these differences are associated with body fat and serum levels of leptin, insulin, and glucose. ⋯ Obese women showed rCBF differences in areas related to the frontoparietal neural circuit, the default mode network, and the salience network, suggesting loss of cognitive control and a higher perception of physiologic processes, such as hunger. Hyperactivation in these areas might jeopardize the recognition of changes in energy homeostasis.

The purpose of this study was to explore the effect of trimethylamine (TMA)-degrading probiotic agents on trimethylamine oxide (TMAO) and the related lipid metabolism in mice. ⋯ Bif. animalis subsp. lactis F1-3-2 could be colonized in the cecum, and might directly degrade TMA or change the structure of intestinal flora. The strain had an effect on TMA and TMAO levels in vivo by decreasing cecum TMA. The strain was demonstrated to participate in the TMA-TMAO regulation, improve the lipid metabolism, and alleviate atherosclerosis caused by TMAO. However, FMO3 had not changed in this process, and needs further study.

This study aimed to explore the effects of glutamine on hypermetabolic reactions in burned rats and its underlying mechanism. ⋯ Glutamine administration effectively reduces hypermetabolic reactions by promoting NADPH synthesis, inhibiting oxidative stress, and improving glutamine utilization after burn injury.

The aim of this study was to verify the accuracy of the SARC-F and the SARC-CalF as screening tools for sarcopenia in community-dwelling older women ≥60 y of age. ⋯ The present study findings suggested that SARC-CalF may be able to outperform SARC-F as a sarcopenia screening tool in women ≥60 y of age even under the new EWGSOP2 criteria, the main determinant of which is strength as observed in studies based on the previous definition.

The aim of this study is to validate the Global Leadership Initiative on Malnutrition (GLIM) criteria and determine the number of Nutritional Risk Screening 2002 (NRS2002)-positive patients who do not meet the GLIM, as well as examine whether these patients would benefit from nutritional support therapy. ⋯ The GLIM criteria have been validated, and are useful in identifying malnourished patients who may have fewer infection complications due to nutritional support therapy. However, the criteria neglected half of the patients identified by NRS2002, among whom nutritional support therapy also decreased the rate of infection complications.
