Associations between EP-like lesions and pleuritis and post trimming carcass weights of finishing pigs in England

Herd health slaughter checks regularly identify enzootic pneumonia-like (EP-like) lesions and pleuritis. The aim of this paper is to determine the associations between these lesions and post-trimming carcass weight. Data were collected on the presence/absence and severity of EP-like lesions and presence/absence of pleuritis from pigs at the abattoir. Linear mixed models identified a significant association between an increase in EP-like lesion severity and a decrease in post-trimming carcass weight (P = 0.006) at the individual level. Each categorical increase in EP-like lesion severity (5 points step) was associated with a 0.37 kg reduction in post-trimming carcass weight. The presence of EP-like lesions in individual pigs, irrespective of severity (P = 0.034) and the presence of pleuritis (P = 0.038) were significantly associated with a reduction in post-trimming carcass weight of 1.26 kg and 1.25 kg respectively. The results confirm that the presence of these lesions at slaughter are associated with a significant decrease in production performance which can result in substantial economic implications for producers

Risk of cancer in patients with dermatomyositis or polymyositis, and follow-up implications: a Scottish population-based cohort study

We conducted a national, retrospective population-based cohort study of 705 patients hospitalized with a first diagnosis of dermatomyositis (DM) or polymyositis (PM) during 1982–1996 based on linkage of hospital discharge, cancer registration, and death records in Scotland. Risks of cancer were assessed by calculating standardized incidence ratios (SIR). A first malignancy was diagnosed concurrently or subsequently in 50 patients with DM (SIR 7.7, 95% CI 5.7–10.1), and 40 patients with PM (2.1, 1.5–2.9). Significantly elevated risks were observed for lung, cervix uteri, and ovarian cancer in patients with DM, and for Hodgkin’s disease in patients with PM. The excess risk of cancer was highest around the time of diagnosis, and for patients with DM remained high for at least 2 years. Risks were elevated for both sexes but only significantly so for females, and were highest in patients aged 45–74 years at the time of diagnosis for DM and 15–44 for PM. © 2001 Cancer Research Campaign http://www.bjcancer.co

Creative haptics: an evaluation of a haptic tool for non-sighted and visually impaired design students, studying at a distance

Design students who are blind or sight-impaired face distinct challenges when studying a visually centric discipline such as design practice. Students who are sighted use computer-aided design (CAD) which is presented via high definition using a PC mouse. However, design students who are blind or sight-impaired are not able to use visual display technology; therefore, this creates a barrier to access for this community. The aim of this study is to present a haptic prototype trial (Haptic Application Prototype Test [HAPT]) designed to assist design students who are blind/sight-impaired to interact with prototype assembly at the Open University (OU). The study specifically assessed the user feedback and the efficacy of access to CAD interface through the affordances of the haptic interface. The experiment included two groups of participants: one group included students who were blind and sight-impaired and the second group students who were classed fully sighted. Both groups were tested in two conditions of haptic engagement – manual and virtual. The parameters examined were (a) time – set at an industry-recognized time taken to assemble a ‘sketch model’ or prototype, and (b) ncollision – the number of collisions created by a collision algorithm which calculated any random collisions with the virtual environment or objects therein. Quantitative results showed that there was little statistical difference between time and a between-group test. From this we can imply that the haptic interface had offered equal access to CAD for people in the trial who were sighted and blind/sight-impaired indiscriminate of their sight acuity. Further future work using HAPT could be developed to a wider audience and a larger more diverse range of sight-impaired users. Future work will focus on new explorations of teaching using of haptics for greater immersion for distance learners at the OU science, technology, engineering and mathematics (STEM) labs

Hardy's inequality for functions vanishing on a part of the boundary

The changing association between socioeconomic circumstances and the incidence of colorectal cancer: a population-based study

Background:There is emerging evidence to suggest that the association between socioeconomic circumstances and colorectal cancer incidence has changed over recent decades.Methods:We conducted a descriptive population-based study to describe the relationship between socioeconomic circumstances and the incidence of colorectal cancer in a pre-screened population. Incident cases of colorectal cancer from the West of Scotland were identified from the Scottish Cancer Registry and European age-standardised incidence rates (EASR) were calculated. Socioeconomic circumstances were measured using the area-based Scottish Index of Multiple Deprivation (SIMD).Results:In total, 14?051 incident cases of colorectal cancer were recorded from 1999 to 2007. Incidence of colorectal cancer was associated with increased deprivation in men but not among women; an association that became evident from 2005 onwards. From 2005 to 2007, the deprivation gap in incidence among men was 13.3 per 100?000 (95% confidence interval 3.2-23.4), with rates 19.5% lower among the least deprived compared with the most deprived. This deprivation gap now accounts for an estimated 75 excess cases per year of male colorectal cancer in the West of Scotland.Conclusion:Deprivation was associated with higher incidence rates of male, but not female, colorectal cancer before the implementation of a national bowel screening programme
