TL;DR: It is concluded that oral 5-ASA administered in a dosage of 4.8 g per day is effective therapy, at least in the short term, for mildly to moderately active ulcerative colitis.
Abstract: We assessed oral 5-aminosalicylic acid (5-ASA) prepared with a pH-sensitive polymer coating in 87 patients with mildly to moderately active ulcerative colitis in a double-blind, placebo-controlled trial. Patients were randomly assigned to receive 5-ASA at a dosage of either 4.8 or 1.6 g per day or placebo for six weeks. The outcome was monitored by flexible proctosigmoidoscopic examinations and physicians' assessments at three-week intervals and by patients' recordings of daily symptoms. Results showed 24 percent complete and 50 percent partial responses in those receiving 4.8 g of 5-ASA per day as compared with 5 percent complete and 13 percent partial responses in those receiving placebo (P less than 0.0001, rank-sum test). At a dosage of 1.6 g per day, the response was twice as good as with placebo, but the difference did not reach statistical significance (P = 0.51). Age, sex, duration of disease, duration of active symptoms, or extent of disease did not affect the clinical outcome. We conclude that oral 5-ASA administered in a dosage of 4.8 g per day is effective therapy, at least in the short term, for mildly to moderately active ulcerative colitis.

TL;DR: In patients with severe aortic stenosis who are at increased surgical risk, TAVR with a self-expanding transcatheter aorti-valve bioprosthesis was associated with a significantly higher rate of survival at 1 year than surgical aorticsvalve replacement.
Abstract: BACKGROUND We compared transcatheter aortic-valve replacement (TAVR), using a self-expanding transcatheter aortic-valve bioprosthesis, with surgical aortic-valve replacement in patients with severe aortic stenosis and an increased risk of death during surgery. METHODS We recruited patients with severe aortic stenosis who were at increased surgical risk as determined by the heart team at each study center. Risk assessment included the Society of Thoracic Surgeons Predictor Risk of Mortality estimate and consideration of other key risk factors. Eligible patients were randomly assigned in a 1:1 ratio to TAVR with the self-expanding transcatheter valve (TAVR group) or to surgical aortic-valve replacement (surgical group). The primary end point was the rate of death from any cause at 1 year, evaluated with the use of both noninferiority and superiority testing. RESULTS A total of 795 patients underwent randomization at 45 centers in the United States. In the as-treated analysis, the rate of death from any cause at 1 year was significantly lower in the TAVR group than in the surgical group (14.2% vs. 19.1%), with an absolute reduction in risk of 4.9 percentage points (upper boundary of the 95% confidence interval, −0.4; P<0.001 for noninferiority; P = 0.04 for superiority). The results were similar in the intention-to-treat analysis. In a hierarchical testing procedure, TAVR was noninferior with respect to echocardiographic indexes of valve stenosis, functional status, and quality of life. Exploratory analyses suggested a reduction in the rate of major adverse cardiovascular and cerebrovascular events and no increase in the risk of stroke. CONCLUSIONS In patients with severe aortic stenosis who are at increased surgical risk, TAVR with a self-expanding transcatheter aortic-valve bioprosthesis was associated with a significantly higher rate of survival at 1 year than surgical aortic-valve replacement.

TL;DR: The age-adjusted incidence of AF increased significantly in Olmsted County during 1980 to 2000 and the projected number of persons with AF for the United States will exceed 10 million by 2050, underscoring the urgent need for primary prevention strategies against AF development.
Abstract: Background— Limited data exist on trends in incidence of atrial fibrillation (AF). We assessed the community-based trends in AF incidence for 1980 to 2000 and provided prevalence projections to 2050. Methods and Results— The adult residents of Olmsted County, Minnesota, who had ECG-confirmed first AF in the period 1980 to 2000 (n=4618) were identified. Trends in age-adjusted incidence were determined and used to construct model-based prevalence estimates. The age- and sex-adjusted incidence of AF per 1000 person-years was 3.04 (95% CI, 2.78 to 3.31) in 1980 and 3.68 (95% CI, 3.42 to 3.95) in 2000. According to Poisson regression with adjustment for age and sex, incidence of AF increased significantly (P=0.014), with a relative increase of 12.6% (95% CI, 2.1 to 23.1) over 21 years. The increase in age-adjusted AF incidence did not differ between men and women (P=0.84). According to the US population projections by the US Census Bureau, the number of persons with AF is projected to be 12.1 million by 2050, ...

TL;DR: A consensus-based approach was applied, supplemented by input from international experts who reviewed the report, and a dyspepsia subgroup classification is proposed for research purposes, based on the predominant (most bothersome) symptom.
