Generalizability of Randomized Controlled Trials to Routine Clinical Care in Ulcerative Colitis.

Background: Historically, randomized controlled trials (RCTs) have been criticized for being poorly generalizable to patients with ulcerative colitis (UC) evaluated in routine care. We aimed to evaluate the proportion of patients with UC starting an advanced therapy who would be eligible to participate in phase 3 registrational UC RCTs.

Methods: We conducted a retrospective cohort analysis of UC patients starting vedolizumab, ustekinumab, or tofacitinib at 2 IBD clinics at the University of Calgary.

Implementation and Evaluation of a Virtual Skills-Based Dementia Caregiver Group Intervention within a VA Setting: A Pilot Study.

Objectives: This study sought to design, implement, and evaluate a 6-week skills-based telehealth group for dementia caregivers within a VA setting.

Methods: The protocol was designed based on a CBT skill-building approach and was evaluated using the four levels of evaluation developed by Kirkpatrick (1998). Eight spousal caregivers of individuals with MCI or dementia participated in the pilot group within a VA geriatric clinic.

US National Estimates of Contemporary Mortality Rates in Patients With Ulcerative Colitis Undergoing Colectomy.

Introduction: Despite a growing armamentarium of medical therapies for ulcerative colitis, colectomy remains an important therapeutic option. To better inform shared decision-making about surgery, we estimated the contemporary risk of mortality after colectomy.

Methods: Mortality rates were estimated using the National Inpatient Sample (2016-2020).

Use of tRNA gene barriers improves stability of transgene expression in CHO cells.

Instability of transgene expression is a major challenge for the biopharmaceutical industry, which can impact yields and regulatory approval. Some tRNA genes (tDNAs) can resist epigenetic silencing, the principal mechanism of expression instability, and protect adjacent genes against the spread of repressive heterochromatin. We have taken two naturally occurring clusters of human tDNAs and tested their ability to reduce epigenetic silencing of transgenes integrated into the genome of Chinese hamster ovary (CHO) cells.

Graded Multidimensional Clinical and Radiologic Variation in Patients With Alzheimer Disease and Posterior Cortical Atrophy.

Background And Objectives: Alzheimer disease (AD) spans heterogeneous typical and atypical phenotypes. Posterior cortical atrophy (PCA) is a striking example, characterized by prominent impairment in visual and other posterior functions in contrast to typical, amnestic AD. The primary study objective was to establish how the similarities and differences of cognition and brain volumes within AD and PCA (and by extension other AD variants) can be conceptualized as systematic variations across a transdiagnostic, graded multidimensional space.
