Objective To analyze the impact of body mass index (BMI) on hospitalization process of colorectal cancer patients served by West China Hospital, based on the current version of Database from Colorectal Cancer (DACCA). Methods The data of DACCA was updated on April 30, 2021. All data items included BMI, visiting data, admission date, operation date, discharging date, pre-hospitalization time, pre-operation time, post-operation time, total hospital stay, and management process. Results After scanning, 5 564 data rows were analyzed, from 2007 to 2021. The range of BMI was 11.02–39.67 kg/m2, the average of BMI was (22.86±3.28) kg/m2, and the BMI increased with year \begin{document}$ (\widehat{y} $\end{document}=0.058x–94.23, R2=0.005, P<0.001). The results of BMI characteristic analysis showed that BMI was not statistically significant related to the pre-hospitalization time, the pre-operation time, and the total length of hospital stay (P>0.05). However, the BMI would affect patients’ postoperative hospital stay and process management (P<0.05). Among them,obese group had shorter postoperative hospital stay than other groups (P=0.014). Additionally, there was significant difference in management process among colorectal cancer patients with different BMI (χ2=26.84, P=0.001). In process management, “ERAS” management accounted for the largest proportion (66.37%), but for each process management category, lean people were more likely to choose “enhanced” management process (11.08%), and obese people were more likely to choose “individual” process management (6.05%). Conclusions The analysis results reflect that the BMI of colorectal cancer patients have an increasing trend year by year. BMI has no clear correlation with patients’ waiting time before admission, pre-operative time, and total hospital stay. Therefore, from the perspective of hospitalization management, the hospitalization operation ability of patients with colorectal cancer was not affected by BMI. The BMI of patients will affect the postoperative hospital stay and process management. The obese people have a shorter postoperative hospital stay and are more likely to choose non-process management.
In this study we performed Tissue Doppler Imaging (TDI), two-dimensional speckle tracking imaging (2D-STI) and three-dimensional speckle tracking imaging (3D-STI) on enrolled healthy, overweight and obese groups (34 subjects in each group), respectively, to analyze cardiac structure and its function. Compared with healthy group, global longitudinal strain (GLS), global circumferential strain (GCS), global area strain(GAS) and global radial strain (GRS) decreased progressively (P＜0.05). The ratio of early diastolic mitral inflow velocity to global early diastolic strain rate of left ventricle (E/e′sr) (r=0.466, P＜0.001), GLS(r=0.502, P＜0.001), GCS(r=0.426, P＜0.001), GAS(r=0.535, P＜0.001) and GRS(r=-0.554, P＜0.001) were correlated with body mass index (BMI). E/e′sr (r=0.37, P=0.003), GLS(r=0.455, P＜0.001), GCS(r=0.282, P=0.02), GAS(r=0.412, P＜0.001) and GRS (r=-0.471, P＜0.001) were correlated with free fatty acid (FFA). Stepwise multiple linear regression revealed that BMI was independently correlated with E/e′sr, GLS, GCS, GAS and GRS. Waist to hip ratio (WHR) was independently correlated with GLS, GCS, GAS and GRS. FFA was independently correlated with E/e′sr(P＜0.05). The study showed that cardiac structure changed and impaired left ventricular global systolic and diastolic function in overweight and obes population. Moreover, BMI, WHR and FFA may be independent influence factors of cardiac function in overweight and obese population.
Objective To review recent advancement of the relationship between obesity and gastric cancer. Method We searched PubMed, Medline, EMBASE, Cochrane Library databases, CNKI, and WanFang database for recent clinical trials about the impact of obesity on occurrence, surgery outcomes, and prognosis of gastric cancer. Results Obesity significantly increased the risk of adenocarcinoma of esophagogastric junction (AEG), increased difficulty in radical operation of gastric cancer and complications of perioperative period, but it had no effect on the long-term operative outcomes. The association between obesity and the survival of gastric cancer was not clear. However, the better survival was observed in most researches of gastric cancer patients with excess body weight. Conclusions The relationship between obesity and gastric cancer is very complex, and there is no consistent conclusion. A reasonable body weight by a healthy lifestyle is expected to decline the incidence of AEG.
ObjectivesTo systematically review the association between body mass index (BMI) and mortality of chronic obstructive pulmonary disease (COPD).MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect cohort studies on the association between BMI and mortality of COPD from inception to February, 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.ResultsA total of 14 cohort studies involving 494 060 COPD patients were included. The results of meta-analysis showed that, compared with patients having a normal weight, underweight individuals were associated with higher mortality (RR=1.40, 95%CI 1.15 to 1.71, P=0.000 8), whereas overweight (RR=0.65, 95%CI 0.54 to 0.79, P<0.000 1) and obese (RR=0.37, 95%CI 0.20 to 0.67, P=0.001) patients were associated with lower mortality.ConclusionsCurrent evidence shows that underweight is associated with a higher risk of all-cause mortality among patients with COPD, whereas overweight and obese are associated with lower risk of all-cause mortality in these patients. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
