Granulomas at initial diagnosis of Crohn’s disease signal a poor outcome

Background. Over time, most patients with Crohn’s disease (CD) develop strictures or fistulas, resulting in hospitalisations and surgery. Timely therapy with immunomodulators and biologicals may alter this natural history, but carries a significant risk of side-effects.Objective. To identify factors to predict poor-outcome severe CD at diagnosis, and thus patients who would benefit most from early, aggressive medical therapies.Methods. CD patients (n=101) with uncomplicated non-stricturing, non-penetrating disease at diagnosis, and with follow-up >5 years, were retrospectively analysed using a predefined definition of severe CD (SCD) over the disease course. Clinical, demographic, laboratory and histological factors at diagnosis associated with SCD and poor outcome were evaluated by univariate and multivariate analysis.Results. Overall 33.7% of the cohort developed SCD, and on multivariate Cox proportional hazard analysis the presence of granulomas on endoscopic biopsy at diagnosis was independently associated with development of SCD (hazard ratio (HR) 2.3; 95% confidence interval (CI) 1.15 - 4.64; p=0.02). Simple perianal disease was also associated with this outcome (HR 2.49; 95% CI 1.14 - 5.41; p=0.02). The presence of these variables had a specificity of 99% and a positive predictive value of 88%.Conclusion. At diagnosis, factors predictive of SCD in our referral centre were the presence of endoscopic biopsy granulomas and perianal disease. Patients with these risk factors should be considered for early, aggressive medical therapy, as benefit will probably outweigh risk. To our knowledge, this is the first study to show that endoscopic biopsy granulomas in patients with uncomplicated (non-stricturing, nonpenetrating) CD predict the subsequent development of SCD

Metric-based vs peer-reviewed evaluation of a research output: Lesson learnt from UK’s national research assessment exercise

Purpose There is a general inquisition regarding the monetary value of a research output, as a substantial amount of funding in modern academia is essentially awarded to good research presented in the form of journal articles, conferences papers, performances, compositions, exhibitions, books and book chapters etc., which, eventually leads to another question if the value varies across different disciplines. Answers to these questions will not only assist academics and researchers, but will also help higher education institutions (HEIs) make informed decisions in their administrative and research policies. Design and methodology To examine both the questions, we applied the United Kingdom’s recently concluded national research assessment exercise known as the Research Excellence Framework (REF) 2014 as a case study. All the data for this study is sourced from the openly available publications which arose from the digital repositories of REF’s results and HEFCE’s funding allocations. Findings A world leading output earns between £7504 and £14,639 per year within the REF cycle, whereas an internationally excellent output earns between £1876 and £3659, varying according to their area of research. Secondly, an investigation into the impact rating of 25315 journal articles submitted in five areas of research by UK HEIs and their awarded funding revealed a linear relationship between the percentage of quartile-one journal publications and percentage of 4* outputs in Clinical Medicine, Physics and Psychology/Psychiatry/Neuroscience UoAs, and no relationship was found in the Classics and Anthropology/Development Studies UoAs, due to the fact that most publications in the latter two disciplines are not journal articles. Practical implications The findings provide an indication of the monetary value of a research output, from the perspectives of government funding for research, and also what makes a good output, i.e. whether a relationship exists between good quality output and the source of its publication. The findings may also influence future REF submission strategies in HEIs and ascertain that the impact rating of the journals is not necessarily a reflection of the quality of research in every discipline, and this may have a significant influence on the future of scholarly communications in general. Originality According to the author’s knowledge, this is the first time an investigation has estimated the monetary value of a good research output

Emotional processing and Social Cognition in Amyotrophic Lateral Sclerosis

Building on evidence for cognitive-behavioural change in people with Amyotrophic Lateral Sclerosis (ALS), the current study uses a range of neuropsychological measures to delineate the nature and scope of reported deficits in emotional processing and social cognition in people with ALS. Compared to the healthy control group, the ALS group was impaired on composite scores indexing executive function and performance on the emotional processing and social cognition tasks. Single-case analyses revealed that ALS patients showed heterogeneous performance across the cognitive tasks

The role of contracting strategies in social value implementation

There has been an increasing demand for social value (SV) implementation to assume a cardinal position in the infrastructure delivery efforts of infrastructure client organisations (ICOs). However, whereas successful implementation has been recorded in some projects, monumental failures have also been recorded in others. This variance in implementation performance is a cause for concern. The mode of governance applied in an infrastructure delivery endeavour has been identified as capable of influencing the implementation of SV. This observation makes imperative an investigation into the role of contracting strategies – an integral part of governance modes – adopted by ICOs on SV implementation performance. This is the aim of this study. Using a case study approach, three infrastructure projects which used different contracting strategies were selected from two different countries, the UK and Nigeria. Semistructured interviews were conducted with ICO representatives on these projects and subsequently analysed using qualitative content analysis. Findings confirmed that the kind of contract adopted by ICOs influenced their ability to drive the successful implementation of desirable SV objectives through their supply chain. It is therefore recommended that ICOs ensure that the selected contracting strategies are capable of ensuring successful implementation of the desired objectives

An audit of provincial gastroenterology services in the Western Cape

Background: While disorders such as gastro-oesophageal reflux disease, gastrointestinal (GI) cancers and inflammatory bowel disease are prevalent among all racial groups in the Western Cape, there is little knowledge of local GI service provision. The state of equipment, facilities and staffing is largely unrecorded and to date unknown. The aim of this study was to audit the availability of GI facilities in the provincial sector, which provides care for the majority of people in the Western Cape. Method: All hospitals in the Western Cape providing endoscopy were evaluated by means of a hands-on audit, to identify available organisational infrastructure. Data including staffing, details and utilisation of existing equipment, maintenance and disinfection techniques and delays in service provision were collected. Results: Over a period of 12 months, 17 Western Cape hospitals were visited : 3 tertiary, 5 regional and 9 district-level institutions. There are currently 89 GI endoscopes in state service, with an average age of 6.1 years (range 1 - 23 years). While most institutions utilise video endoscopy, in many instances equipment is near the end of its economic life. A total of 26 434 endoscopic procedures were performed over a 12-month period. Overall at least 60% of all adult endoscopy was undertaken at tertiary institutions. The mean delay from consultation until gastroscopy or colonoscopy was 9.25 weeks (range 0.5 - 28 weeks) and 8 weeks (range 1 - 20 weeks), respectively. Only 1 tertiary and 1 regional hospital employed fully trained, registered nurses, and the majority of institutions did not conform to internationally accepted standards for the maintenance and disinfection of endoscopic equipment. Conclusion: While endoscopy equipment is widely distributed throughout the province, it is evident from this study that services in the Western Cape fall short of international standards, with delays in endoscopic provision, lack of adequate equipment, inadequate scope maintenance and disinfection and a shortage of trained staff. As such, much of the population reliant on state facilities has poor access to GI health care. These deficiencies need to be addressed

The Clostridium difficile problem: A South African tertiary institution's prospective perspective

BACKGROUND AND OBJECTIVES: The aim of this study is to report the incidence of Clostridium difficile-associated disease (CDAD) in a tertiary-care hospital in South Africa and to identify risk factors, assess patient outcomes and determine the impact of the hypervirulent strain of the organism referred to as North American pulsed-field type 1 (NAP1). METHODS: Adults who presented with diarrhoea over a period of 15 months were prospectively evaluated for CDAD using stool toxin enzyme immunoassay (EIA). Positive specimens were evaluated by PCR. Patient demographics, laboratory parameters and outcomes were analysed. RESULTS: CDAD was diagnosed in 59 (9.2%) of 643 patients (median age 39 years, IQR 30 - 55). Thirty-four (58%) were female. Recent antibiotic exposure was reported in 39 (66%), 27 (46%) had been hospitalised within 3 months, and 14 (24%) had concomitant inflammatory bowel disease (IBD). Nineteen (32%) had community-acquired CDAD (CA-CDAD). The annual incidence of hospital-acquired CDAD (HA-CDAD) was 8.7 cases/10 000 hospitalisations. Two cases of the hypervirulent strain NAP1 were identified. Seven (12%) patients underwent colectomy (OR 6.83; 95% CI 2.41 - 19.3). On logistic regression, only antibiotic exposure independently predicted for CDAD (OR 2.9; 95% CI 1.6 - 5.1). Three (16%) cases of CA-CDAD reported antibiotic exposure (v. 90% of HA-CDAD, p<0.0001). Twelve (86%) patients had concomitant IBD (p<0.0001 v. HA-CDAD). CA-CDAD was significantly associated with antibiotic exposure (OR 0.04, 95% CI 0.01 - 0.24) and IBD (OR 9.6, 95% CI 1.15 - 79.8). CONCLUSION: The incidence of HA-CDAD in the South African setting is far lower than that reported in the West. While antibiotic use was a major risk factor for HA-CDAD, CA-CDAD was not associated with antibiotic therapy. Concurrent IBD was a predictor of CA-CDAD

Epidemiology of inflammatory bowel disease in sub-Saharan Africa: A review of the current status

While inflammatory bowel disease (IBD) has been well characterised in the West and other parts of the world, there are little data from sub-Saharan Africa (SSA). To throw light on the current status of IBD in SSA, we performed a systematic review of the literature, extracting relevant publications. We found only 210 documented IBD cases in SSA (excluding South Africa (SA)), which were reported in 34 publications until August 2019. The majority were cases of ulcerative colitis. Only three reports, all from SA, attempted to determine IBD incidence rates. The rest were mostly case reports or small case series; the largest from Nigeria comprised 32 patients. The paucity of documented cases possibly reflects under-diagnosis and under-reporting. Major deficiencies in diagnostic and clinical capacity were noted, which need to be addressed going forward

Rationalising "for" and "against" a policy of school-led careers guidance in STEM in the U.K. : a teacher perspective

This paper reports on teacher attitudes to changes in the provision of careers guidance in the U.K., particularly as it relates to Science, Technology, Engineering and Mathematics (STEM). It draws on survey data of n = 94 secondary-school teachers operating in STEM domains and their attitudes towards a U.K. and devolved policy of internalising careers guidance within schools. The survey presents a mixed message of teachers recognising the significance of their unique position in providing learners with careers guidance yet concern that their ‘relational proximity’ to students and ‘informational distance’ from higher education and STEM industry may produce bias and misinformation that is harmful to their educational and occupational futures
