| 1 | Older adults with acute severe ulcerative colitis have similar steroid non-response and colectomy rates as younger adults显示文摘BACKGROUND There is paucity of data on outcomes of acute severe ulcerative colitis(ASUC)in older adults(≥60 years of age).AIM To assess steroid non-response rates during the index admission for ASUC in older adults.Secondary outcomes were response to medical rescue therapy and colectomy rates;at index admission,3 and 12 mo.METHODS This retrospective multicentre cohort study included ASUC admissions who received intravenous steroids between January 2013 and July 2020 at two tertiary hospitals.Electronic medical records were reviewed to collect clinical,biochemical,and endoscopic data.A modified Poisson regression model was used for analysis.RESULTS Of 226 ASUC episodes,45(19.9%)occurred in patients≥60 years of age.Steroid non-response rates were comparable in older adults and patients<60 years of age[19(42.2%)vs 85(47%),P=0.618],crude risk ratio(RR)=0.89[95%confidence interval(CI):0.61-1.30],adjusted RR=0.99(0.44-2.21).Rates of response to medical rescue therapy in older adults was comparable to the younger cohort[76.5%vs 85.7%,P=0.46,crude RR=0.89(0.67-1.17)].Index admission colectomy[13.3%vs 10.5%,P=0.598,crude RR=1.27(0.53-2.99),adjusted RR=1.43(0.34-6.06)],colectomy at 3 mo[20%vs 16.6%,P=0.66,crude RR=1.18(0.61-2.3),adjusted RR=1.31(0.32-0.53)]and colectomy at 12 mo[20%vs 23.2%,P=0.682,crude RR=0.85(0.45-1.57),adjusted RR=1.21(0.29-4.97)],were similar between the two groups.CONCLUSION In older adults with ASUC,the steroid non-response rate,response to medical rescue therapy,and colectomy rate at index admission,3 and 12 mo is similar to patients less than 60 years of age. | Deloshaan Subhaharan Pradeep Kakkadasam Ramaswamy Laura Willmann Hadi Moattar Maneesha Bhullar Naveed Ishaq Alexander Dorrington Dheeraj Shukla Carolyn McIvor John Edwards Waled Mohsen | 2023 | World Journal of Gastroenterology2023，29，16： | 0 |
| 2 | To scope or not-the challenges of managing patients with positive fecal occult blood test after recent colonoscopy显示文摘BACKGROUND Colorectal cancer(CRC) is a major health problem. There is minimal consensus of the appropriate approach to manage patients with positive immunochemical fecal occult blood test(iFOBT), following a recent colonoscopy.AIM To determine the prevalence of advanced neoplasia in patients with a positive iFOBT after a recent colonoscopy, and clinical and endoscopic predictors for advanced neoplasia.METHODS The study recruited i FOBT positive patients who underwent colonoscopy between July 2015 to March 2020. Data collected included demographics, clinical characteristics, previous and current colonoscopy findings. Primary outcome was the prevalence of CRC and advanced neoplasia in a patient with positive iFOBT and previous colonoscopy. Secondary outcomes included identifying any clinical and endoscopic predictors for advanced neoplasia.RESULTS The study included 1051 patients(male 53.6%;median age 63). Forty-two(4.0%) patients were diagnosed with CRC, 513(48.8%) with adenoma/sessile serrated lesion(A-SSL) and 257(24.5%) with advanced A-SSL(AA-SSL). A previous colonoscopy had been performed in 319(30.3%). In this cohort, four(1.3%) were diagnosed with CRC, 146(45.8%) with A-SSL and 56(17.6%) with AA-SSL. Among those who had a colonoscopy within 4 years, none had CRC and 7 had AA-SSL. Of the 732 patients with no prior colonoscopy, there were 38 CRCs(5.2%). Independent predictors for advanced neoplasia were male [odds ratio(OR) = 1.80;95% confidence interval(CI): 1.35-2.40;P < 0.001), age(OR = 1.04;95%CI: 1.02-1.06;P < 0.001) and no previous colonoscopy(OR = 2.07;95%CI: 1.49-2.87;P < 0.001).CONCLUSION A previous colonoscopy, irrespective of its result, was associated with low prevalence of advanced neoplasia, and if performed within four years of a positive iFOBT result, was protective against CRC. | Nivedita Rattan Laura Willmann Diana Aston Shani George Milan Bassan David Abi-Hanna Sulakchanan Anandabaskaran George Ermerak Watson Ng Jenn Hian Koo | 2022 | World Journal of Gastrointestinal Oncology2022，14，9： | 0 |
