Objectives: To investigate public awareness of colorectal cancer (three components: total knowledge, confidence and anticipated delay) in the Chinese population, to explore factors associated with total knowledge and to elucidate relationships among three components of public awareness of colorectal cancer. Methods: We recruited 562 adult Chinese participants with no history of colorectal cancer between March and May 2020 by convenience sampling method. Data were collected online using a self‐designed demographic questionnaire and a simplified Chinese version of the Bowel Cancer Awareness Measure. Univariate analysis and multivariate linear regression were applied. Results: The mean score for total knowledge was 10.56 (SD: 5.89). Over half of the participants (58.2%) lacked confidence about detecting warning signs. For 42.7% of participants, the anticipated delay was not within the acceptable range (2 weeks). Totally eight demographic variables were identified as significant predictors of total knowledge, accounting for 36.2% of the variance. Total knowledge was positively correlated with confidence (r = 0.126, p < 0.01) and negatively associated with anticipated delay (F = 8.891, p < 0.01). Conclusion: Public awareness of colorectal cancer was low in the Chinese population. Hence, educational interventions targeted for improving knowledge, enhancing individuals' confidence in detecting symptoms and reducing barriers to seeking medical help may be urgently required.

Background. The relationship between heart rate in CAD patients who underwent percutaneous coronary intervention (PCI) and had long-term outcomes over up to 10 years of follow-up has not been investigated. Methods. All patients were from the CORFCHD-PCI, a retrospective cohort study that included a total of 6050 CAD patients who underwent PCI from January 2008 to December 2016. One patient was excluded due to a lack of heart rate data. Ultimately, 6049 patients were enrolled. The primary outcome was long-term mortality after PCI. Results. Patients were divided into 5 groups according to heart rate quintiles: 1st quintile (heart rate <66 beats/min; n=1123), 2nd quintile (heart rate ≥66 beats/min to 72 beats/min; n=1010), 3rd quintile (heart rate ≥72 beats/min to 78 beats/min; n=1442), 4th quintile (heart rate ≥78 beats/min to 84 beats/min; n=1211), and 5th quintile (heart rate ≥84 beats/min; n=1263). After multivariate Cox regression analyses, the respective risks of ACM, CM, and MACEs were increased 79.1% (hazard risk (HR) = 1.791, 95% CI: 1.207–2.657, P=0.004), 56.9% (HR = 1.569, 95% CI: 1.019–2.416, P=0.041), and 25.5% (HR = 1.255, 95% CI: 0.990–1.590, P=0.060) in the 4th quintile and 98.7% (HR = 1.987, 95% CI: 1.344–2.937, P=0.001), 98.8% (HR = 1.988, 95% CI: 1.310–3.016, P<0.001), and 0.36.1% (HR = 1.361, 95% CI: 1.071–1.730, P=0.012) in the 5th quintile compared with those in the 1st quintile. Patients with a heart rate of ≥80 beats/min had 89.4%, 115.2%, and 39.1% increased risk of ACM, CM, and MACEs, respectively, compared to those patients with a heart rate of <80 beats/min. Conclusion. The present study indicated that the resting heart rate is an independent predictor of adverse long-term outcomes in CAD patients who underwent PCI. [ABSTRACT FROM AUTHOR]
