Review Meta Analysis
Prevalence and prognostic value of sarcopenic obesity in patients with cancer: A systematic review and meta-analysis.
The aim of this study was to conduct a systematic review and meta-analysis of observational studies to estimate the overall prevalence and prognostic value of sarcopenic obesity (SO) in patients with cancer. We searched PubMed, Embase, Web of Science and the Cochrane Library for observational studies reporting the prevalence of SO and its prognosis in patients with cancer from inception to December 2020. The pooled prevalence, hazard ratios (HRs), odds ratios (ORs) and their 95% confidence intervals (CIs) of data extracted from the studies were calculated. ⋯ Current limited evidence suggested that SO may be associated with poor cancer-specific survival (HR, 5.00; 95% CI, 1.40-16.70), but not progression-free survival (HR, 0.61; 95% CI, 0.32-1.16). The present review indicated SO is common in patients with cancer and is significantly associated with several poor outcomes. Therefore, it is necessary to diagnose and screen for SO in patients with cancer in the future, and appropriate interventions should be further explored to improve the prognosis of cancer patients.

Randomized Controlled Trial
Taurine as a possible antiaging therapy: A controlled clinical trial on taurine antioxidant activity in women ages 55 to 70.
Based on the antioxidant effects of taurine, which are capable of controlling oxidative stress in the aging process, the aim of this study was to investigate the effects of taurine supplementation on biomarkers of oxidative stress in women 55 to 70 y of age. ⋯ Taurine supplementation prevented the decrease in the antioxidant enzyme SOD, suggesting taurine as a strategy to control oxidative stress during the aging process.

Randomized Controlled Trial
Immunomodulating versus high-protein oral preoperative supplement in surgical patients - A two-center, prospective, randomized clinical trial.
For many years, immunonutrition was believed to reduce postoperative complications in patients undergoing major abdominal surgery. However, recent studies questioned that belief. Moreover, the perioperative intake of proteins has gained more and more attention and has shown clinical value. Therefore, the aim of this study was to compare the clinical effect of immunomodulating (IM) plus high-protein (HP) and pure HP supplements during the preoperative period. ⋯ Both groups were comparable in terms of age, sex, and type of surgery. The median length of postoperative hospital stay was 8 d (range, 6-12 d) in the IM group and 7 d (range, 6-10 d) in the HP group (P = 0.153). Postoperative complications were observed in 29 patients (21.3%) in the IM group and 28 (17.8%) in the HP group (P = 0.442) The risk of readmission was comparable (5.1% vs 4.9%; P = 0.924) for IM and HP supplements, respectively. Postoperative nausea and vomiting occurred in 21 patients in the IM group (15.4%) and 17 patients in the HP group (10.4%; P = 0.195). No difference in gastrointestinal function evaluated with time to first flatus was observed (P = 0.272) CONCLUSIONS: The study demonstrated no difference between preoperative IM + HP and HP supplements in surgical patients. Therefore, the routine preoperative use of IM supplements in all surgical patients cannot be recommended.

The present study aimed to identify associations between extremes in body weight status (underweight and excess body weight) before a COVID-19 diagnosis and clinical outcomes in patients infected with SARS coronavirus type 2. ⋯ Being underweight and excess body weight were not independently associated with clinical outcomes in patients with COVID-19 in the herein analyzed cohort. This finding indicates that the association between these variables may be confounded by both age and comorbidities.

Intake of dietary fibers promotes the production of short-chain fatty acids (SCFAs), which can affect host inflammation via gut microbial fermentation. Although partially hydrolyzed guar-gum (PHGG) is a water-soluble dietary fiber with lower viscosity, its benefits in acute inflammation are yet to be determined. The aim of this study was to investigate the effect of PHGG intake on the lipopolysaccharide (LPS)-induced tumor necrosis factor (TNF)-α production. ⋯ These results demonstrated that inflammation was inhibited by habitual PHGG ingestion, suggesting that this phenomenon might be associated with changes in gut microbiota-induced SCFAs production.
