TL;DR: This is the first demonstration of substantial and significantly increased risk for both noteworthy bleeding (requiring transfusion) and perforation from cecal polypectomy for a given polyp size, compared with elsewhere in the colon.
Abstract: Background and study aims: The English National Health Service Bowel Cancer Screening Programme (NHSBCSP) is one of the world’s largest organized screening programs. Minimizing adverse events is essential for any screening program. Study aims were to determine rates and to examine risk factors for adverse events. Patients and methods: Bleeding and perforations in NHSBCSP colonoscopies between August 2006 and January 2012 were examined. Logistic regression was used to examine risk factors for adverse events, including age, gender, polyp size, morphology, and location. For accurate attribution of adverse events, procedures with resection of only one polyp (“single-polypectomy”) were analyzed in detail. Results: 130 831 colonoscopies (167 208 polypectomies) were analyzed, including 30 881 single-polypectomies. Overall bleeding rate was 0.65 %, rate of bleeding requiring transfusion was 0.04 % and perforation rate was 0.06 %. Polypectomy increased bleeding risk 11.14-fold and perforation risk 2.97-fold. Cecal location (but not elsewhere in the proximal colon) and increasing polyp size were the two most important risk factors for bleeding and perforation. After adjustment for polyp size, the odds ratio (OR) relative to the distal colon for bleeding requiring transfusion after cecal snare polypectomy was 13.5 (95 %CI 3.9 – 46.4) and for perforation after cecal nonpedunculated polypectomy it was 12.2 (95 %CI 1.2 – 119.5). Conclusion: This is the largest study focusing on polyp-specific risk factors. We have confirmed that the greatest risk factor for both post-polypectomy bleeding and perforation is polyp size. This is the first demonstration of substantial and significantly increased risk for both noteworthy bleeding (requiring transfusion) and perforation from cecal polypectomy for a given polyp size, compared with elsewhere in the colon.

01 May 1999TL;DR: The evidence available suggests that widespread adoption of a vegetarian diet could prevent approximately 40,000 deaths from IHD in Britain each year.
Abstract: Compared with non-vegetarians, Western vegetarians have a lower mean BMI (by about 1 kg/m2), a lower mean plasma total cholesterol concentration (by about 0.5 mmol/l), and a lower mortality from IHD (by about 25%). They may also have a lower risk for some other diseases such as constipation, diverticular disease, gallstones and appendicitis. No differences in mortality from common cancers have been established. There is no evidence of adverse effects on mortality. Much more information is needed, particularly on other causes of death, other morbidity including osteoporosis, and long-term health in vegans. The evidence available suggests that widespread adoption of a vegetarian diet could prevent approximately 40,000 deaths from IHD in Britain each year.

TL;DR: Moderate physical activity is associated with a lower risk of coronary heart disease, venous thromboembolic event, and cerebrovascular disease than inactivity, however, among active women, there is little to suggest progressive reductions in risk of vascular diseases with increasing frequency of activity.
Abstract: Background—Although physical activity has generally been associated with reduced risk of vascular disease, there is limited evidence about the effects of the frequency and duration of various activities on the incidence of particular types of vascular disease. Methods and Results—In 1998, on average, 1.1 million women without prior vascular disease reported their frequency of physical activity and many other personal characteristics. Three years later, they were asked about hours spent walking, cycling, gardening, and housework each week. Women were followed by record linkage to National Health Service cause-specific hospital admissions and death records. Cox regression was used to calculate adjusted relative risks for first vascular events in relation to physical activity. During an average of 9 years follow-up, 49 113 women had a first coronary heart disease event, 17 822 had a first cerebrovascular event, and 14 550 had a first venous thromboembolic event. In comparison with inactive women, those repor...

TL;DR: Investigation of possible risk factors for prematurity, low birthweight and small-for-gestational-age (SGA) in singleton IVF births in Great Britain indicated that hypertension during pregnancy was an independent risk for preterm delivery, low Birthweight and SGA, and the number of embryos transferred and the type of infertility for low birth Weight.
Abstract: The Medical Research Council In-Vitro Fertilization (IVF) Register report on births resulting from assisted conception in Great Britain demonstrated a high incidence of preterm and low birthweight babies. This incidence remained high even when the analysis was restricted to singleton babies. The present paper investigates possible risk factors for prematurity, low birthweight and small-for-gestational-age (SGA) in singleton IVF births. Thirteen per cent of singleton IVF babies were preterm, 11% low birthweight and 17% small-for-gestational-age. Analysis by multiple regression indicated that hypertension during pregnancy was an independent risk for preterm delivery, low birthweight and SGA, bleeding during pregnancy for preterm delivery, and the number of embryos transferred and the type of infertility for low birthweight.
