Ulcerative colitis (UC) is a chronic and progressive inflammatory disorder that affects the colon. The advent of advanced therapies such as biologic agents and small molecules has revolutionized the management of UC. Despite the expanding therapeutic armamentarium of advanced therapies to treat UC, the overall net remission rates and durability of currently available agents are relatively low. This highlights the need for further drug development and more innovative clinical trial design. There are currently multiple emerging agents in the pipeline for the management of UC. This includes agents with alternative routes of administration such as oral or subcutaneous tumor necrosis factor inhibitors or novel mechanisms of action such as toll-like receptor 9 (TLR9) agonist cobitolimod and phosphodiesterase 4 inhibitor apremilast. In this review, we will highlight novel and emerging advanced therapies currently in the pipeline for the management of UC.

Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorders. A pooled analysis showed a global prevalence of 11.2%. Few studies looked at the prevalence of IBS in health care providers. The aim of this study was to determine the prevalence of IBS among board-certified physicians and surgeons. Board-certified physicians and surgeons in Saudi Arabia were invited to complete a web-based survey. It included questions regarding participant demographics, specialty, practice type and hours worked per week. The Rome IV-validated questionnaire was used to identify subjects with IBS. The primary outcome of the study was the prevalence of IBS among physicians. Secondary outcomes included exploring the effect on IBS prevalence of age, gender, marital status, work hours, specialty, gastroenterology subspecialty and working in a public versus private hospital. The final analysis included 594 subjects, with 419 males and a median age of 41. The vast majority (86%) were married. Nearly 90% worked in a public hospital exclusively, and the median number of hours worked per week was 48. The overall prevalence of IBS was 16.3%. In a binary logistic regression model, age (odds ratio [OR] = 0.931, P < 0.0001), gender (OR = 0.504, P = 0.003) and work hours (OR = 2.397, P < 0.0001) significantly predicted the presence of IBS. Marital status and specialty did not predict IBS prevalence. This cross-sectional study shows that the prevalence of IBS among physicians in Saudi Arabia to be 16.3%. IBS was more common in females, those who worked longer hours and younger physicians. There was no association between practicing certain specialties and IBS. However, the lack of difference in our cohort may be attributed to the relatively small sample size from each specialty.

A 41-year-old woman with autosomal dominant polycystic kidney disease had chronic kidney disease class IV. She presented 10 days postpartum with a 4-day history of severe hematuria, left flank pain, and anemia, hemoglobin 62 g/L. CT scan showed massively enlarged kidneys with multiple cysts; several cysts bilaterally had high attenuation consistent with hemorrhage. Hematuria persisted over several days despite intensive conservative measures that included vitamin K1, 4 units of plasma, transfusion of 10 units of packed RBCs, Darbopoeitin, and DDAVP. Antifibrinolytic therapy was given with tranexamic acid 1000 mg p.o. t.i.d for one day then OD. The hematuria stopped within 24 hours and did not recur after tranexamic acid therapy ended. Over the next 4 years there were 3 hospitalizations each with severe gross hematuria requiring blood transfusion for acute anemia. The hematuria responded well to further treatment with tranexamic acid. Tranexamic acid produces antifibrinolytic effects via complex interactions with plasminogen, displacing plasminogen from the fibrin surface. Chronic renal impairment is considered a relative contraindication to use of tranexamic acid due to reports of ureteric clots and acute renal failure from cortical necrosis. We conclude that tranexamic acid can be used safely in some patients with CKD and polycystic kidney disease to treat severe hematuria.

BACKGROUND: Digestive symptoms are common in adults. However, little is known about their prevalence in older adults and the association of digestive symptoms with institutionalization and mortality in community-dwelling older adults.OBJECTIVE: To determine the prevalence of digestive symptoms among older adults in Canada and whether they are associated with increased risk of institutionalization and mortality, independent of the effect of potential confounders.METHODS: The present study was a secondary analysis of data collected from community-dwelling participants 65 years of age and older in the Canadian Study of Health and Aging. Measures incuded age, sex, presence of digestive symptoms, cognition, impairment in activities of daily living (ADL) and self-reported health. Outcome measures included death or institutionalization over the 10 years of follow-up.RESULTS: Digestive symptoms were found in 2288 (25.6%) of the 8949 subjects. Those with digestive symptoms were older, with a mean difference in age of six months (P=0.007). Digestive symptoms were more common among women (28.4%) than men (20.3%), among individuals with poor self-reported health and those with an increased number of impairments in their ADLs (P<0.001). The presence of digestive symptoms was associated with higher mortality (HR 1.15 [95% CI 1.05 to 1.25] adjusted for age, sex, cognitive function and ADL impairment); however, this association was not statistically significant after adjusting for self-reported health.CONCLUSION: Although digestive symptoms were associated with increased mortality independent of age and sex, cognition and function, this association was largely explained by poor self-assessed health. Digestive symptoms were not associated with institutionalization

Context: The number of women in academic medicine has increased significantly in recent years. However, female authors are underrepresented in major medical journals. Objective: The aim was to determine the distribution of female first and senior authors of original articles in four American endocrinology journals over a period of 25 years. Design: A retrospective analysis of the literature was undertaken. Setting: Four journals were selected: Journal of Clinical Endocrinology & Metabolism; Thyroid; Journal of Bone and Mineral Research and Diabetes Care. Participants: The first and senior authors of all original articles published in 1991, 1996, 2001, 2006 and 2015 were included. Intervention: none. Results: The main outcome measure was the distribution of female first and senior authors of original articles. A total of 4 148 articles were included. Of these, 28.9% (1 199) articles were authored by females of whom 751 (62%) were first authors. Over the study period, there was a shift towards female authorship. A statistically significant trend was observed (p < 0.001).

Introduction: Fulminant hepatic failure is a serious disease with significant mortality and morbidity. Identifying the exact cause of hepatic failure and predicting prognosis is of paramount importance in managing such patients. Drug-induced liver injury is a common but challenging entity to treat. The use of newer drugs and medications with previously unknown hepatotoxicity add to the challenges faced by treating physicians. Quetiapine is an antipsychotic that has rarely been linked to acute liver injury. In the present work we describe a case of fulminant hepatic failure secondary to use of quetiapine. Case presentation: A 59-year-old Caucasian woman with known Parkinson’s disease was being treated with quetiapine for hallucinations. She was referred to our hospital with yellow discoloration of the sclera and later on developed clinical features suggestive of hepatic encephalopathy. A diagnosis of fulminant hepatic failure was made following her admission to the intensive care unit. Her condition improved after discontinuing the drug and providing the standard supportive treatment. Conclusions: Our findings in the present report emphasize the importance of keeping an open mind in cases of fulminant hepatic failure. As drug-induced hepatotoxicity is the most common cause of fulminant hepatic failure in many parts of the world, consideration should be given to the medication(s) patients receive as the potential cause and a review of this list should be part of the clinical care given.
