Background & Aims: Because post-polypectomy surveillance uses a growing proportion of colonoscopy capacity, more targeted surveillance is warranted. We therefore compared surveillance burden and cancer detection using 3 different adenoma classification systems.
Methods: In a case-cohort study among individuals who had adenomas removed between 1993 and 2007, we included 675 individuals with colorectal cancer (cases) diagnosed a median of 5.
Article Synopsis
- The study aims to assess the risk of non-Hodgkin's lymphoma (NHL) and Hodgkin's lymphoma (HL) in patients diagnosed with inflammatory bowel disease (IBD) in Norway and Sweden from 1987 to 2016.
- Analyzing data from over 131,000 IBD patients, researchers found a slightly elevated risk for NHL and HL, particularly in those with ulcerative colitis, Crohn's disease, or those undergoing specific treatments like thiopurines and anti-TNF-α.
- While the statistical risk for developing these lymphomas in IBD patients is significantly higher than the general population, the overall absolute risk remains low, indicating that not all IBD patients will develop lymphoma.
Background: Uncertainty prevails about the magnitude of excess risk of small bowel cancer in patients with inflammatory bowel disease (IBD).
Patients And Methods: To quantify the risk of small bowel adenocarcinoma and neuroendocrine tumors in patients with ulcerative colitis (UC) and Crohn's disease (CD), we undertook a population-based cohort study of all patients with IBD diagnosed in Norway and Sweden from 1987 to 2016. Patients were followed through linkage to national registers.
Background: There is continued uncertainty regarding the risks of hepato-pancreato-biliary cancers in patients with inflammatory bowel disease (IBD) with or without concomitant primary sclerosing cholangitis (PSC).
Objective: To give updated estimates on risk of hepato-pancreato-biliary cancers in patients with IBD, including pancreatic cancer, hepatocellular carcinoma, gall bladder cancer, and intra - and extrahepatic cholangiocarcinoma.
Methods: In a population-based cohort study, we included all patients diagnosed with IBD in Norway and Sweden from 1987 to 2016.
Background: Closed fitness centers during the Covid-19 pandemic may negatively impact health and wellbeing. We assessed whether training at fitness centers increases the risk of SARS-CoV-2 virus infection.
Methods: In a two-group parallel randomized controlled trial, fitness center members aged 18 to 64 without Covid-19-relevant comorbidities, were randomized to access to training at a fitness center or no-access.
