The Effect of Post-operative Exercise in Colorectal Cancer Patients: A Pilot Randomized Controlled Trial (RCT) Study

PURPOSE: The purpose of this study was to examine the effect of post-operative exercise on body composition, psychological factors, time to flatus and length of hospital stay in stage 1~3 colorectal cancer patients. METHODS: A total of 35 post surgery patients were recruited and randomly assigned to the exercise or controlled group. Participants in the exercise group exercised twice a day while participants in the control group followed the clinical pathways (CP). RESULTS: A total of 25 participants completed the trial. Post-operative exercise resulted in a clinically meaningful, but statistically insignificant reduction in body weight (Exercise: -1.10±1.63 kg vs. CP: -0.63±1.16 kg; p=.111), fat mass (Exercise: -1.43±0.95 kg vs. CP: 0.64±4.29 kg; p=.100). When participants' body composition were compared to their baseline values at the baseline, only the exercise group experienced a significant reduction in body weight, body mass index (BMI) and fat mass. In addition, post-operative exercise significantly improved health related quality of life (Exercise: 2.27±2.08 vs CP: -12.82±22.47; p=.008). However, there was no difference in time to flatus and the length of hospital stay between groups. CONCLUSION: The current pilot study suggests that the post-operative exercise program was safe and produced for health related quality of life improvements in colorectal cancer patients.

The Relationship between Resting Heart Rate and Prevalence of Metabolic Syndrome and Type 2 Diabetes Mellitus in Korean Adults: The Fifth Korea National Health and Nutrition Examination Survey (2012)

BACKGROUND: The purpose of this study was to examine the association between resting heart rate (RHR), the risk factors and prevalences of metabolic syndrome (MetS) and type 2 diabetes (T2D) in Korean adults. METHODS: A cross sectional analysis was performed on data from the 2012 Korea National Health and Nutrition Examination Survey (KNHANES V) using frequency analysis, analysis of covariance (ANCOVA), and logistic regression. Participants were stratified according to RHR into 5 groups; or =90 bpm. RESULTS: The results show that risk factors of MetS and T2D increased as RHR increased. Compared to those with a RHR of or =90 bpm by 1.46 (95% confidence interval [CI] 1.03-2.08), 2.05 (95% CI, 1.42-2.96), 2.34 (95% CI, 1.57-3.48), and 2.34 (95% CI, 1.23-4.47), respectively. Similarly, compared to those with a RHR of or =90 bpm by 1.01 (95% CI, 0.72-1.41), 1.44 (95% CI, 1.02-2.05), 1.83 (95% CI, 1.25-2.68), and 2.40 (95% CI, 1.30-4.44), respectively. CONCLUSION: In conclusion, RHR was significantly associated with risk factors and prevalences of MetS and T2D. This study suggests that RHR is associated with MetS and T2D and can be used to predict such diseases.
