A Habitat for Humanity and University Partnership: Enhancing on International Experiential Learning in El Salvador

The increase in international experiential learning (IEL hereafter) opportunities being developed by universities in the global north requires more attention both generally and with regards to specific IEL programming objectives. This paper provides observations and assessment of a case study of university-student participation in home-builds in El Salvador over the course of three years – a partnership between Habitat for Humanity and a Canadian university. The information collected is assessed relative to the key critiques and to the recommendations advocated in the IEL literature, with the intention of incorporating these critiques and recommendations in future IEL planning for this partnership, and to inform IEL work more generally. The key observations and recommendations include the need for enhanced student preparation pre and post-trip – meaning ‘critical reflection’ processes and materials on privilege and personal goals themes; on specific global south context; and enhancing on intercultural learning and awareness activities and processes e.g., more closely integrated host-community and participant relationship-building opportunities. These recommendations are seen as important for enhancing on this specific IEL program and its short-duration time-frame, while suggesting useful guideposts for IEL more generally, as its occurrence increases within the university setting

Treat to Target: A Proposed New Paradigm for the Management of Crohn's Disease.

International audience: The traditional management of CD, based on progressive, step-wise treatment intensification with re-evaluation of response according to symptoms, does not improve long-term outcomes of CD and places patients at risk for bowel damage. The introduction of novel therapies and the development of new approaches to treatment in rheumatoid arthritis led to better outcomes for patients. Prominent among these is a "treat to target" strategy that is based on regular assessment of disease activity using objective clinical and biological outcome measures and the subsequent adjustment of treatments. This approach is complementary to the concept of early intervention in high risk patients. This review evaluates current literature on this topic and proposes a definition for the concept treating to targets for Crohn's disease

A review of RCTs in four medical journals to assess the use of imputation to overcome missing data in quality of life outcomes

Background: Randomised controlled trials (RCTs) are perceived as the gold-standard method for evaluating healthcare interventions, and increasingly include quality of life (QoL) measures. The observed results are susceptible to bias if a substantial proportion of outcome data are missing. The review aimed to determine whether imputation was used to deal with missing QoL outcomes. Methods: A random selection of 285 RCTs published during 2005/6 in the British Medical Journal, Lancet, New England Journal of Medicine and Journal of American Medical Association were identified. Results: QoL outcomes were reported in 61 (21%) trials. Six (10%) reported having no missing data, 20 (33%) reported ≤ 10% missing, eleven (18%) 11%–20% missing, and eleven (18%) reported >20% missing. Missingness was unclear in 13 (21%). Missing data were imputed in 19 (31%) of the 61 trials. Imputation was part of the primary analysis in 13 trials, but a sensitivity analysis in six. Last value carried forward was used in 12 trials and multiple imputation in two. Following imputation, the most common analysis method was analysis of covariance (10 trials). Conclusion: The majority of studies did not impute missing data and carried out a complete-case analysis. For those studies that did impute missing data, researchers tended to prefer simpler methods of imputation, despite more sophisticated methods being available.The Health Services Research Unit is funded by the Chief Scientist Office of the Scottish Government Health Directorate.

Reliability and Initial Validation of the Ulcerative Colitis Endoscopic Index of Severity

Background & AimsWe studied the reliability of the previously described Ulcerative Colitis Endoscopic Index of Severity (UCEIS) and validated it with an independent cohort of investigators.MethodsWe created a new library of 57 videos of flexible sigmoidoscopy and stratified them based on disease severity. Twenty-five investigators were each randomly assigned to assess 28 videos (which included 4 duplicates to assess intraobserver reliability). Investigators were blinded to clinical details except for 2 of 4 duplicated videos (to assess the impact of knowledge of symptoms on assessment). Three descriptors (“vascular pattern”, “bleeding”, and “erosions and ulcers”) comprising the UCEIS were scored with a visual analogue scale (VAS) to assess overall severity. Intrainvestigator and interinvestigator agreement was characterized by κ statistical analysis; reliability ratios were used to compare VAS and UCEIS scores.ResultsThere was a high level of correlation between UCEIS scores and overall assessment of severity (correlation coefficient, 0.93). Internal consistency (Cronbach α analysis) was 0.86. Intrainvestigator and interinvestigator reliability ratios for UCEIS scores were 0.96 and 0.88, respectively. Intrainvestigator agreement in determination of the UCEIS score was good (κ = 0.72), with individual descriptors ranging from a κ of 0.47 (for bleeding) to 0.87 (for vascular pattern). Interinvestigator agreement in determination of UCEIS scores was moderate (κ = 0.50), with descriptors ranging from a κ of 0.48 (for bleeding) to 0.54 (for vascular pattern). Intrainvestigator variability in determining UCEIS scores did not change appreciably when a video was presented with clinical details.ConclusionsThe UCEIS and its components show satisfactory intrainvestigator and interinvestigator reliability. Among investigators, the UCEIS accounted for a median of 86% of the variability in evaluation of overall severity on the VAS when assessing the endoscopic severity of UC and was unaffected by knowledge of clinical details

Standardisation of intestinal ultrasound scoring in clinical trials for luminal Crohn's disease

Background: Intestinal ultrasound (IUS) is a valuable tool for assessment of Crohn’s disease (CD). However, there is no widely accepted luminal disease activity index. / Aims: To identify appropriate IUS protocols, indices, items, and scoring methods for measurement of luminal CD activity and integration of IUS in CD clinical trials. / Methods: An expert international panel of adult and paediatric gastroenterologists (n = 15) and radiologists (n = 3) rated the appropriateness of 120 statements derived from literature review and expert opinion (scale of 1-9) using modified RAND/UCLA methodology. Median panel scores of 1 to ≤3.5, >3.5 to <6.5 and ≥6.5 to 9 were considered inappropriate, uncertain and appropriate ratings respectively. The statement list and survey results were discussed prior to voting. / Results: A total of 91 statements were rated appropriate with agreement after two rounds of voting. Items considered appropriate measures of disease activity were bowel wall thickness (BWT), vascularity, stratification and mesenteric inflammatory fat. There was uncertainty if any of the existing IUS disease activity indices were appropriate for use in CD clinical trials. Appropriate trial applications for IUS included patient recruitment qualification when diseased segments cannot be adequately assessed by ileocolonoscopy and screening for exclusionary complications. At outcome assessment, remission endpoints including BWT and vascularity, with or without mesenteric inflammatory fat, were considered appropriate. Components of an ideal IUS disease activity index were identified based upon panel discussions. / Conclusions: The panel identified appropriate component items and applications of IUS for CD clinical trials. Empiric evidence, and development and validation of an IUS disease activity index are needed

Sustainable Development for Rural Areas: A Survey on the Agritourism Rural Networks

The topic of sustainable growth is becoming central in the debate over the rural development policies. Rural communities can completely fulfil the new challenges in the area of sustainability only with the implementation of innovative forms of collaborations among their business networks. In this work, we consider a particular form of business collaboration arising within rural communities, namely Agritourism Rural Network (ARN). In an ARN, a farm, providing agritourism activities, represents a touchpoint between a network of business and organizations in a rural area and tourists interested in enjoying the local territory. With the aim to deeper the extend of the agritourism phenomenon in a rural region and the potential of the related ARNs in being means of sustainable development, we report main results of an empirical survey carried out in 2016 on a sample of 105 agritourism farms all belonging to the same region (Calabria, Italy). Results confirm our intuitions about the importance at farm level of setting agritourism activities and their impact for the ARN related to the farm and for the sustainable development of a local community as a whole
