Many lessons were learned from the implementation and management of tissue banks around the world. The availability of skin allografts can be improved through strategic investments in governance and regulatory structures, international cooperation initiatives, training programs, standardized protocols, and inclusive public awareness campaigns. Further, capacity-building efforts that involve key stakeholders may increase rates of pledges, donations, and transplantations. Some issues were ubiquitously reported and could be addressed by current and future tissue banking programs to ensure allograft availability for patients living in countries of all income levels.Currently, the main targets of drug therapy for ulcerative colitis [UC] are endoscopic and clinical remission. Calcitriol mouse However, there is active discussion about the additional advantages of including histological remission as a target. Accumulating evidence indicates that microscopic activity persists in endoscopically quiescent UC, that histological changes may lag behind clinical remission after treatment, and that absence of histological activity predicts lower rates of relapse, hospitalisation, surgery, and subsequent neoplasia. Obtaining useful information from mucosal biopsies in this setting depends on accurate and consistent evaluation of histological features. However, there is no standardisation of biopsy procedures, histological sample processing technique, or histological scoring systems, and there is no agreement on the definitions of histological remission, response or activity. Accordingly, a consensus expert panel convened by the European Crohn's and Colitis Organisation [ECCO] reviewed the literature and agreed a number of position statements regarding harmonisation of UC histopathology. The objective was to provide evidence-based guidance for the standardisation and harmonisation of procedures, definitions, and scoring systems for histology in UC, and to reach expert consensus where possible. We propose the absence of intraepithelial neutrophils, erosion and ulceration as a minimum requirement for the definition of histological remission. For randomised control trials we recommend the use of the Robarts histopathology index [RHI] or the Nancy index [NI]. For observational studies or in clinical practice we recommend the use of the NI. To predict the risk of future neoplasia in UC, cumulative histological scores over time are more useful than single scores.Background and aims To improve management of patients with Crohn's disease, objective measurements of disease activity are needed. Ileocolonoscopy is the current reference standard but has limitations that restrict repeated use. Ultrasonography is potentially useful for activity monitoring, but no validated sonographic activity index is currently in widespread use. Thus, we aimed to construct and validate a simple ultrasound score for Crohn's disease. Methods 40 patients were prospectively examined with ultrasound and endoscopy in the development phase. The Simple Endoscopic Score for Crohn's Disease (SES-CD) was used as reference standard. Seven ultrasound variables (bowel wall thickness, length, colour Doppler, stenosis, fistula, stratification and fatty wrapping) were initially included, and multiple linear regression was used to select the variables that should be included in the final score. Secondly, the ultrasound data from each patient were re-examined for interobserver assessment using weighted kappavity.We describe the clinical course of 57 children with coronavirus disease 2019 (COVID-19) cared for through a single hospital system. Most children were mildly symptomatic, and only a few patients with underlying medical conditions required hospitalization. System-wide patient evaluation processes allowed for prompt identification and management of COVID-19 patients.Background We hypothesized that renin-angiotensin system (RAS) blockers have systemic protective effects beyond the respiratory tract and could reduce the risk of viral infections. Methods We used the National Health Insurance Research Database and identified two study cohorts the angiotensin receptor blocker (ARB) cohort and angiotensin-converting-enzyme inhibitor (ACEI) cohort. Propensity score matching was applied at a 11 ratio by all associated variables to select two independent control cohorts for the ARB and ACEI cohorts. A Cox proportional hazards model was applied to assess the end outcome of viral infection. Results The numbers of ARB and ACEI users were 20,207 and 18,029, respectively. The median ages (interquartile ranges [IQRs]) of ARB users and nonusers were 53.7 and 53.8years, respectively. The median (IQRs) follow-up duration of ARB users and nonusers was 7.96 and 7.08 years; the median (IQRs) of follow-up duration of ACEI users and nonusers was 8.70 and 8.98 years, respectively. The incidence rates of viral infections in ARB users and nonusers were 4.95 and 8.59 per 1000 person-years, respectively, and ARB users had a lower risk of viral infection than nonusers (adjusted hazard ratios [aHRs], 0.53; 95% confidence interval [CI], 0.48-0.58). The incidence rates of viral infections in ACEI users and nonusers were 6.10 per 1,000 person-years and 7.72 per 1,000 person-years, respectively, and ACEI users had a lower risk of viral infection than nonusers (aHR, 0.81; 95% CI, 0.74-0.88). Conclusion Hypertensive patients using either ARBs or ACEIs exhibit a lower risk of viral infection than nonusers.Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease of the central nervous system. The role of diet in the progression of MS and severity of symptoms remains unclear. Various systematic literature reviews (SRs) have reported the effects of single nutrients on MS progression or the role of dietary factors on specific symptoms of MS. Narrative reviews have examined the effects of various dietary patterns in MS populations. An umbrella review was undertaken to collate the findings from review articles and evaluate the strength of the scientific evidence of dietary interventions for people living with MS. Scientific databases including MEDLINE, PubMed, CINAHL, and The Cochrane Library were systematically searched up to April 2019. Review articles and meta-analyses were included if they examined the effect of any dietary intervention in adult populations with MS. Outcomes included MS progression indicated by relapses, disability, MRI activity and disease classification, and MS symptoms. Characteristics and findings from both review articles and their included primary studies were extracted and summarized.
