Aspects of dietary carbohydrate intake are not related to risk of colorectal polyps in the Tennessee Colorectal Polyp Study

Purpose: High digestible carbohydrate intakes can induce hyperglycemia and hyperinsulinemia and collectively have been implicated in colorectal tumor development. Our aim was to explore the association between aspects of dietary carbohydrate intake and risk of colorectal adenomas and hyperplastic polyps in a large case–control study.

Methods: Colorectal polyp cases (n = 1,315 adenomas only, n = 566 hyperplastic polyps only and n = 394 both) and controls (n = 3,184) undergoing colonoscopy were recruited between 2003 and 2010 in Nashville, Tennessee, USA. Dietary intakes were estimated by a 108-item food frequency questionnaire. Unconditional logistic regression analysis was applied to determine odds ratios (OR) and corresponding 95 % confidence intervals (CI) for colorectal polyps according to dietary carbohydrate intakes, after adjustment for potential confounders.

Results: No significant associations were detected for risk of colorectal adenomas when comparing the highest versus lowest quartiles of intake for total sugars (OR 1.03; 95 % CI 0.84–1.26), starch (OR 1.01; 95 % CI 0.81–1.26), total or available carbohydrate intakes. Similar null associations were observed between dietary carbohydrate intakes and risk of hyperplastic polyps, or concurrent adenomas and hyperplastic polyps.

Conclusion: In this US population, digestible carbohydrate intakes were not associated with risk of colorectal polyps, suggesting that dietary carbohydrate does not have an etiological role in the early stages of colorectal carcinogenesis.

Sports Law

The term sports law is fourfold in nature and encompasses: (a) traditional areas of law, such as contract, tort, criminal, administrative and EU law, as applied to disputes of a sporting origin; (b) the particular impact that a range of statutory provisions might have on sport; for example, legislation governing discriminatory and unsafe practices in a workplace or monopolistic or fraudulent behaviour in an industry; (c) issues of public and social policy otherwise influencing the legislature and the courts, from the allocation of resources to the allocation of risk; and (d) lex sportiva, where that term is taken to reflect the various internal administrative regulations and awards by dispute-resolving mechanisms in sport. As a matter of practice, sports law tends to be concerned with the application of contract and commercial law principles to professional sport - and namely the application of such branches of law to disputes relating to the following "three pillars" of modern, professional sport i.e., disputes relating to the payment, sponsorship or endorsement of those who play sport for a living; disputes arising from decisions made by sports governing bodies; and disputes arising from the application of law to the holding of sports events.

Objects of Transcendence: Scots Protestantism and an Anthropology of Things

This anthropological essay takes as its ethnographic point of departure two apparently contrasting deployments of the Bible within contemporary Scotland, one as observed among Brethren and Presbyterian fisher-families in Gamrie, coastal Aberdeenshire, and the other as observed among the Orange Order, a Protestant marching fraternity, in Airdrie and Glasgow. By examining how and with what effects the Bible and other objects (plastic crowns, ‘Sunday clothes’, Orange regalia) enter into and extend beyond the everyday practices of fishermen and Orangemen, my aim is to sketch different aspects of the material life of Scottish Protestantism. By offering a critique of Bruno Latour’s early writing on ‘quasi-objects’ via Alfred Gell’s notion of ‘distributed personhood’, I seek to undermine the sociological assumption that modernity and enchantment are mutually exclusive.

A randomized controlled trial on the effects of combined aerobic-resistance exercise on muscle strength and fatigue, glycemic control and health-related quality of life of type 2 diabetes patients

Aim: to evaluate the effects of a 12-weeks combined aerobic-resistance exercise therapy on fatigue and isokinetic muscle strength, glycemic control and health-related quality of life (HRQoL) in moderately affected type 2 diabetes (T2DM) patients. Methods: a randomized controlled trial design was employed. Forty-three T2DM patients were assigned to an exercise group (n = 22), performing 3 weekly sessions of 60 minutes of combined aerobic-resistance exercise for 12-weeks; or a no exercise control group (n = 21). Both groups were evaluated at a baseline and after 12-weeks of exercise therapy for: 1) muscle strength and fatigue by isokinetic dynamometry; 2) plasma glycated hemoglobin A1C (HbA1C); and 3) HRQoL utilizing the SF-36 questionnaire. Results: the exercise therapy led to improvements in muscle fatigue in knee extensors (-55%) and increased muscle strength in knee flexors and extensors (+15 to +30%), while HbA1C decreased (-18%). In addition, the exercising patients showed sizeable improvements in HRQoL: physical function (+53%), vitality (+21%) and mental health (+40%). Conclusion: 12-weeks of combined aerobic-resistance exercise was highly effective to improve muscle strength and fatigue, glycemic control and several aspects of HRQoL in T2DM patients. These data encourage the use of aerobic and resistance exercise in the good clinical care of T2DM.
