Background: Multislice computed tomography (MSCT) permits reliable imaging of not only the coronary artery lumen but also vessel wall. It is assumed that both lipid-rich plaques and those that display positive remodeling are more prone to rupture and erosion with subsequent coronary events. The purpose of this study was to assess the correlation between the characteristics of coronary arteries by MSCT and several measures of coronary heart disease (CHD) risk. Methods: This study consisted of 424 consecutive participants who received MSCT and coronary angiography (CAG). We assessed coronary artery findings including coronary artery calcification (CAC), degree of remodeling and narrowing of lumen and characteristics including uric acid (UA) and high-sensitivity C-reactive protein (hs-CRP). Statistical analyses were conducted for four subgroups classified by the presence of significant stenosis and positive remodeling. Results: Hs-CRP was 2.10 +/- 2.70 mg/L in positive remodeling (+) and stenosis (+) group (PS), 1.05 +/- 0.97 mg/L in positive remodeling (-) and stenosis (+) group (nPS), 0.94 +/- 0.88 mg/L in positive remodeling (+) and stenosis (-) group (PnS) and 0.44 +/- 0.49 mg/L in positive remodeling (-) and stenosis (-) group (nPnS). The results of logistic regression analysis showed that hs-CRP was higher in PS compared with the other groups (p < 0.001) and higher in nPS and PnS compared with nPnS (p < 0.05). Conclusions: Regardless of significant stenosis, positive remodeling by MSCT correlates to the increase of hs-CRP. (C) 2008 Elsevier Ireland Ltd. All rights reserved.

Summary: This study aimed to investigate the relationship between eating speed and the presence of sarcopenia in older patients with type 2 diabetes (T2D). The results showed that patients with a slow eating speed had a higher risk of low skeletal muscle mass, low muscle strength, and sarcopenia compared to those with a fast or normal eating speed.

Summary: This study investigated the potential therapeutic effect of dietary supplementation with PHGG against sarcopenic obesity using Db/Db mice. The results showed that PHGG could increase grip strength and skeletal muscle weight, as well as increase the concentration of short-chain fatty acids in feces and sera. PHGG also exhibited anti-inflammatory effects in the small intestine, indicating its preventive role in sarcopenic obesity.

Summary: People with fast eating habits have an increased risk of diabetes and obesity. A study found that consuming vegetables first, regardless of eating speed, can improve postprandial blood glucose and insulin levels. Compared to consuming carbohydrates first, the food order of vegetables first resulted in significantly lower standard deviation, large amplitude of excursion, and incremental area under the curve for blood glucose and insulin.
