Abstract Background and Aims: Epidemiologic studies provide evidence for a link between obesity or diabetes the risk colorectal cancer. However, there is lack of information about relationship metabolic syndrome adenoma. Therefore, we investigated whether factor Methods: We did study consecutive subjects who underwent colonoscopy as screening exam at Center Health Promotion, Samsung Medical Center, from March 2004 to December 2005. According modified ATP III criteria, was diagnosed....
Obesity is a risk factor for colorectal cancer. However, the effect of body weight change on cancer uncertain. This study aimed to investigate relationship between difference in mass index and In this nationwide population-based cohort study, participants national screening program 2005 2009 were enrolled. Difference was calculated from data 2009. Participants divided into four groups according direction obesity status: non-obese/non-obese, non-obese/obese, obese/non-obese, obese/obese. The...
Abstract Background: Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder in the West. But information on prevalence of IBS Asia still lacking, especially Korea. Therefore, aims present study were to estimate general population Korea and also investigate characteristics health‐care‐seeking behavior patients. Methods: Telephone interview survey was conducted by Gallup, using validated questionnaire based Rome II criteria. The response rate telephone 25.2% ( n =...
Colorectal cancer screening is recommended for average-risk persons beginning at age 50. However, information about the incidence and risk factors of precursor adenoma in preceding decades limited. The aim this study was to determine prevalence colorectal aged 40-49 years compare data with those 30-39 50-59 years.A cross-sectional 5254 asymptomatic subjects who underwent colonoscopy conducted. Data were stratified by into three groups: 608 years, 1930 2716 years.Prevalence overall adenomas...
Abstract Background: Although several studies have investigated excessive salt intake as a risk factor for gastric precancerous lesions, such atrophic gastritis and intestinal metaplasia, the evidence is insufficient to make conclusion. We evaluated association between lesions intake. Methods: From 2008 2015, medical records of 728 subjects who underwent upper gastrointestinal endoscopy sodium excretion in 24-hour urine tests were retrospectively reviewed. Sixty-six excluded due diuretics...
Abstract Computer-aided detection (CADe) systems have been actively researched for polyp in colonoscopy. To be an effective system, it is important to detect additional polyps that may easily missed by endoscopists. Sessile serrated lesions (SSLs) are a precursor colorectal cancer with relatively higher miss rate, owing their flat and subtle morphology. Colonoscopy CADe could help endoscopists; however, the current exhibit very low performance detecting SSLs. We propose system reflects...
To assess longitudinally physical activity patterns and intensity from pre-pregnancy to postpartum evaluate the association between timing type of development gestational diabetes mellitus (GDM). The Korean Pregnancy Outcome Study (KPOS) is a prospective cohort study conducted 2013 2017. Our included 3,457 participants with singleton pregnancies in KPOS, classified according pregnancy outcome: GDM (n=231) normal (n=3,226). Physical data were collected at five time points using short form...
Background/Aims: Atrophic gastritis is considered a premalignant lesion.We aimed to evaluate the risk factors for gastric tumorigenesis in underlying mucosal atrophy.Methods: A total of 10,185 subjects who underwent upper gastrointestinal endoscopy between 2003 and 2004 were enrolled this retrospective cohort study.Follow-up was performed 2005 2014.Atrophic intestinal metaplasia assessed by using Kimura-Takemoto classification.Helicobacter pylori infection evaluated based on serum...
<b>Background and study aims:</b> Subepithelial tumor is a relatively common finding in upper gastrointestinal endoscopy. This aimed to evaluate the natural course of incidentally detected small subepithelial tumors tract analyze risk factors for increase size such tumors. <b>Patients methods:</b> Medical records 1684 patients with between 2004 2013 were retrospectively reviewed. If serial follow-up endoscopy showed significant increase, endoscopic or surgical resection was recommended...
There is minimal research on the effect of overall dietary patterns development nonalcoholic fatty liver disease (NAFLD) in Korean population. The present study investigated association between and NAFLD.A prospective cross-sectional was performed participants who visited a health care center for checkup. A semiquantitative food frequency questionnaire administered to assess their intake, factor analysis used identify patterns. Relationships risk NAFLD were evaluated.A total 331 1190 (27.8%)...
Manual data extraction of colonoscopy quality indicators is time and labor intensive. Natural language processing (NLP), a computer-based linguistics technique, can automate the important clinical information, such as adverse events, from unstructured free-text reports. NLP information facilitate optimization work by helping to improve control patient management.We developed an pipeline analyze pathology reports evaluated its ability automatically assess adenoma detection rate (ADR), sessile...
Background/Aims . Women after menopause have increased insulin resistance and visceral fat, which may increase the prevalence of nonalcoholic fatty liver disease (NAFLD). However, pathogenesis NAFLD in women has not been clearly defined. In this study, we aimed to determine risk factors for women. Methods A retrospective cohort study was conducted. who underwent abdominal ultrasonography blood sampling routine health check-ups were recruited. Results Among 1,423 subjects, 695 (48.9%) a...
Colorectal adenoma and coronary artery disease (CAD) appear to share common risk factors, such as male gender, diabetes mellitus, smoking, obesity. We investigated the relationship between colorectal atherosclerosis, a factor for adenoma.A cross-sectional study was conducted on Korean men who presented health check-up. The subjects were 488 (217 271 normal colonoscopic findings) underwent colonoscopy computed tomography angiography (CTA) same day screening examination. Advanced colonic...
Aims . Chronic low-grade inflammation is thought to be associated with the pathogenesis of nonalcoholic fatty liver disease (NAFLD). This study aimed determine association between serum white blood cell (WBC) counts and development incidental NAFLD. Methods In this retrospective longitudinal cohort study, we recruited participants who underwent abdominal ultrasonography samplings during medical checkups in both 2005 2010. A total 2,216 subjects were included our analyses. Results The...
The incidence of early-onset colorectal cancer (EO-CRC, diagnosed before 50 years age) has increased in recent decades. aim this study was to investigate the association between changes obesity status and EO-CRC risk.From a nationwide population-based cohort, individuals <50 old who participated national health checkup program both 2009 2011 were included. Obesity defined as body mass index ≥25 kg/m2. Abdominal waist circumference ≥ 90 cm men 85 women. Participants classified into 4 groups...
BACKGROUND Although the link between cardiovascular disease (CVD) and various cancers is well-established, relationship CVD risk colorectal cancer (CRC) remains underexplored. AIM To elucidate scores CRC incidence. METHODS In this population-based cohort study, participants from 2009 National Health Checkup were followed-up until 2020. The (CV) score was calculated as sum of factors (age, family history coronary artery disease, hypertension, smoking status, high-density lipoprotein levels)...
Tobacco smoking is a major public health concern worldwide. This study aimed to assess its impact on cancer incidence and mortality by estimating the population attributable fraction (PAF) in Korean for 2015 2020 projecting future trends until 2030. The relative risk (RR) was calculated via meta-analysis of RRs individual cancers attributed tobacco smoking, based primary data analysis from Cohort Consortium. PAF estimated using Levin formula with past current prevalence rates number cases...
This study aimed to determine the population-attributable fractions (PAFs) of cancers using various calculation methods and estimate PAFs cancer incidence mortality resulting from deficit in physical activity (DPA) 2015 2030, based on data prevalence rates. The PAF was estimated a cohort study-based meta-analysis relative risk (RR), national rates DPA 2000 2015, statistics with latency 15 years.
