Background/Aims: Crohn’s disease (CD) may involve the upper parts of the gastrointestinal (GI) tract including the esopha gus, stomach, and duodenum. Clinical features of upper GI CD (UGICD) are not well characterized in the Gulf region. We therefore aimed to assess the prevalence and clinical characteristics of patients diagnosed with UGICD. Methods: We per formed a retrospective analysis of all patients diagnosed with CD who underwent upper GI endoscopy between 2012 and 2017 at King Abdulaziz University Hospital, irrespective of age. Patients who had endoscopy of the upper GI tract at baseline and had histologically confirmed UGICD were included. Data on patients’ demographics, clinical characteristics, extraintestinal mani festations and complications were reviewed. Results: We identified 78 CD patients who underwent upper GI endoscopy from our medical records. The mean age was 17.2±8.7 years and 55.1% were males. Of the total, 19 out of 78 patients (24.4%) had histologically confirmed UGICD (3 esophageal, 16 gastric, and 9 duodenal), of which 52.6% were symptomatic. Disease dis tribution was ileal in 57.8%, colonic in 21.1% and ileo-colonic in 21.1%. A non-stricturing and non-penetrating phenotype was reported in 89.4%, stricturing in 5.3%, and penetrating in 5.3%. Perianal disease was found in 10.5%. UGICD was complicated by stricture formation in 2 patients (esophageal and gastric). Conclusions: The prevalence of UGICD is considered high among CD Saudi patients who undergo upper GI endoscopy at baseline, and is asymptomatic in 47.4% of patients. This reported prev alence is not dissimilar from reports originating from Western countries. (Intest Res 2020;18:210-218)

Epididymal sperm cryopreservation provides a potential method for preserving genetic material from males of endangered species. This pilot study was conducted to develop a freezing method for tiger epididymal sperm. We evaluated post-thaw sperm condition using testes with intact epididymides obtained from a Siberian tiger (Panthera tigris altaica ) after castration. The epididymis was chopped in Tyrode's albumin-lactate-pyruvate 1x and incubated at 5% CO2, 95% air for 10 min. The Percoll separation density gradient method was used for selective recovery of motile spermatozoa after sperm collection using a cell strainer. The spermatozoa were diluted with modified Norwegian extender supplemented with 20 mM trehalose (extender 1) and subsequent extender 2 (extender 1 with 10% glycerol) and frozen using LN2 vapor. After thawing at 37℃ for 25 s, Isolate® solution was used for more effective recovery of live sperm. Sperm motility (computerized assisted sperm analysis, CASA), viability (SYBR-14 and Propidium Iodide) and acrosome integrity (Pisum sativum agglutinin with FITC) were evaluated. The motility of tiger epididymal spermatozoa was 40.1 ± 2.0%, and progressively motile sperm comprised 32.7 ± 2.3%. Viability was 56.3 ± 1.6% and acrosome integrity was 62.3 ± 4.4%. Cryopreservation of tiger epididymal sperm using a modified Norwegian extender and density gradient method could be effective to obtain functional spermatozoa for future assisted reproductive practices in endangered species.

Aims: Current guidelines recommend the use of a basal-bolus insulin regimen in hospitalized patients with hyperglycemia or type 2 DM. In addition a simple strategy facilitating the reconciliation of medication on discharge can improve glycemic control post-discharge. With our study we want to test whether this better glycemic control is maintained over time. Methods: Our study is a prospective and observational study during routine clinical practice. It has been held in an Department of Internal Medicine during hospitalization, with follow-up visit at 3 months after discharge and followed up for 3 years. Study patients (30) were treated with a regimen of basal-bolus insulin during hospitalization and an adjustment of their antidiabetic treatment at discharge. As a control group we included patients(30) hospitalized with similar characteristics, treated with other regimen of insulin or oral antidiabetic agents and to which either no treatment adjustment is recommended at discharge. A follow-up to all patients at 3 months after discharge and again after 3 years I realize. Results: Comparing the study group with the control group we found no differences in baseline HbA1c (8,52%±0,81 vs 8,61%±0.72; p:0,652), age (67,7±3,76 vs 67,8±3,71; p:0,86), sex (16 male vs 17 mal) and BMI (30,33±1,62 Kg/m2 vs 30,41±1,63 Kg/m2). Compared with baseline, the HbA1c at 3 months after discharge is lowe r(7,51%±0.81 vs 8,52%±0,81;p:0,001) and 3 years after discharge also remains lower(7,81%±0,81vs8,52%±0,81; p:0,013). Compared with control subjects, patients included in study have lower HbA1c at 3 months after discharge (7,51%±0,81 vs 8,71% ± 0,81:p:0,004) and lower HbA1c at 3 years after discharge (7,81%±0,81 vs 8,91%±0,81; p:0,002). Conclusion: This study confi rm that protocols to manage hyperglycemia with basal-bolus insulin regimens are also feasible and effective in routine clinical practice, and demonstrate that a simple strategy facilitating the reconciliation of medication on discharge can improve glycemic control post-discharge, that remains after 3 years or follow.
