Objectives: This study aimed to investigate the potential factors associated with adherence to colonoscopy among participants who were preliminarily screened positive in a community-based colorectal cancer screening program in China.
Methods: This study analyzed data from 1219 out of 6971 community residents who were identified as positive cases by the well-validated high-risk factor questionnaire (HRFQ) or fecal immunochemical test (FIT) in the preliminary screening stage for colorectal neoplasms. Patients showing adherence to colonoscopy were defined as those who received positive results in a preliminary screening for colorectal neoplasms and later received a colonoscopy examination as required.
Background: The positive predictive value (PPV) of high risk factor questionnaire (HRFQ) plus fecal immunochemical test (FIT) as preliminary screening strategy for colorectal-related neoplasia is relatively low. We aim to explore independent factors associated with PPVs of HRFQ combined FIT for selecting high risk individuals for colonoscopy.
Methods: A total of 6971 residents were enrolled in a community-based screening program.
Background: Sewage transmission of SARS-CoV-2 has never been demonstrated. During a COVID-19 outbreak in Guangzhou, China in April 2020, we investigated the mode of transmission.
Methods: We collected clinical and environmental samples from quarantined residents and their environment for RT-PCR testing and genome sequencing.
Objective: To analyze the detection rates of colorectal cancer (CRC) and polyps by population-based screening in Guangzhou.
Methods: From January 2011 to December 2015, the residents aged 30-79 were selected for CRC screening. The residents were conducted Questionnaires and/or FOBT to assess high-risk groups, the free colonoscopy examination was recommended, and the results were evaluated in detail.
