BackgroundPhysicians today are increasingly faced with healthcare challenges that require an understanding of global health trends and practices, yet little is known about what constitutes appropriate global health training.MethodsA literature review was undertaken to identify competencies and educational approaches for teaching global health in medical schools.ResultsUsing a pre-defined search strategy, 32 articles were identified; 11 articles describing 15 global health competencies for undergraduate medical training were found. The most frequently mentioned competencies included an understanding of: the global burden of disease, travel medicine, healthcare disparities between countries, immigrant health, primary care within diverse cultural settings and skills to better interface with different populations, cultures and healthcare systems. However, no consensus on global health competencies for medical students was apparent. Didactics and experiential learning were the most common educational methods used, mentioned in 12 and 13 articles respectively. Of the 11 articles discussing competencies, 8 linked competencies directly to educational approaches.ConclusionsThis review highlights the imperative to document global health educational competencies and approaches used in medical schools and the need to facilitate greater consensus amongst medical educators on appropriate global health training for future physicians.

N ew York City is the epicenter of the US coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with local population infection rates estimated at 25%. 1 The impact of COVID-19 on patients with inflammatory bowel disease (IBD) within an epicenter is not well understood. Our study aims were to compare clinical outcomes between COVID-19 patients with and without IBD and to investigate the prevalence and risk factors of COVID-19 in IBD patients.

Fecal calprotectin has a significant diagnostic accuracy for the detection of small-bowel CD. Our results suggest that in patients with suspected CD with calprotectin <50 μg/g, the likelihood of positive diagnosis is very low.

CE, MRE and SICUS have similar DY for detection of SB CD in both suspected and established CD. CE is superior to MRE for detection of proximal SB disease, however the risk of capsule retention should be considered.

Emerging data have highlighted the co-existence of non-alcoholic fatty liver disease (NAFLD) and inflammatory bowel disease; both of which are increasingly prevalent disorders with significant complications and impact on future health burden. Cross-section observational studies have shown widely variable prevalence rates of co-existing disease, largely due to differences in disease definition and diagnostic tools utilised in the studies. Age, obesity, insulin resistance and other metabolic conditions are common risks factors in observational studies. However, other studies have also suggested a more dominant role of inflammatory bowel disease related factors such as disease activity, duration, steroid use and prior surgical intervention, in the development of NAFLD. This suggests a potentially more complex pathogenesis and relationship between the two diseases which may be contributed by factors including altered intestinal permeability, gut dysbiosis and chronic inflammatory response. Commonly used immunomodulation agents pose potential hepatic toxicity, however no definitive evidence exist linking them to the development of hepatic steatosis, nor are there any data on the impact of therapy and prognosis in patient with co-existent diseases. Further studies are required to assess the impact and establish appropriate screening and management strategies in order to allow early identification, intervention and improve patient outcomes.

Compelling moral, ethical, professional, pedagogical, and economic imperatives support the integration of global health topics within medical school curriculum. Although the process of integrating global health into medical education is well underway at some medical schools, there remain substantial challenges to initiating global health training in others. As global health is a new field, faculties and schools may benefit from resources and guidance to develop global health modules and teaching materials. This article describes the Core Competencies project undertaken by the Global Health Education Consortium and the Association of Faculties of Medicine of Canada's Global Health Resource Group.

Background: Biologic therapies in patients with Crohn's disease often yield low clinical and endoscopic remission rates. After multiple failed therapies, combining two biologic therapies is possibly the sole medical alternative to recurrent surgery.However, data on this approach are limited. Aims:To assess the efficacy and safety of concomitant use of two biologic therapies in the largest cohort to date of refractory Crohn's disease patients. Methods: Data were extracted from Crohn's disease patients started on dual biologic therapy at two referral centres. Biologics utilised include infliximab, adalimumab, vedolizumab, ustekinumab, certolizumab and golimumab. The primary outcome was endoscopic improvement (>50% reduction in Simplified Endoscopic Score-Crohn's disease [SES-CD] or explicitly stated). Endoscopic remission (SES-CD < 3 or stated), clinical response (Crohn's disease-patient-reported outcome-2 score [PRO2] reduced by 8), clinical remission (PRO2 < 8), and C-reactive protein (CRP) were also assessed.Results: A total of 22 patients with 24 therapeutic trials of dual biologic therapy were identified. The majority of patients had prior surgical resections (91%), stricturing (59%) or penetrating (36%) phenotype, and perianal fistulas (50%). Median number of prior failed biologics was 4. Endoscopic improvement occurred in 43% of trials and 26% achieved endoscopic remission. Fifty per cent had clinical response and 41% achieved clinical remission. There were significant post-treatment reductions in median ] to 6.0 [2.5-8.0], P = 0.0005], to 13.4 [4.6-21.8], P = 0.002] and .0] to 9.0 [4.0-14.0], P = 0.02).Presence of perianal fistulas decreased from 50% to 33%. Adverse events occurred in 13% of trials. Conclusion:Dual biologic therapy was associated with clinical, biomarker and endoscopic improvements in selected patients with refractory Crohn's disease who failed multiple biologics. Further studies are needed to validate this approach.
