The Impact of Biologic Therapies on Rate of Colectomy in Paediatric-onset Ulcerative Colitis - A Population-Based Cohort Study.

Aim: Biologic therapies have been associated with reduced rate of colectomy in ulcerative colitis (UC) in adults, but data are limited in paediatric-onset UC. Our aim was to define the rate of colectomy in paediatric-onset UC, including post-transition into adult care, and to evaluate the impact of biologic therapies on rate of colectomy.

Method: All prevalent patients diagnosed with paediatric-onset UC in South-East Scotland were identified from a prospectively accrued database at our regional tertiary centre.

Chromatin Landscape Governing Murine Epidermal Differentiation.

Chromatin landscape and regulatory networks are determinants in lineage specification and differentiation. To define the temporospatial differentiation axis in murine epidermal cells in vivo, we generated datasets profiling expression dynamics (RNA sequencing), chromatin accessibility (assay for transposase-accessible chromatin using sequencing), architecture (Hi-C), and histone modifications (chromatin immunoprecipitation followed by sequencing) in the epidermis. We show that many differentially regulated genes are suppressed during the differentiation process, with superenhancers controlling differentiation-specific epigenomic changes.

Intrinsic Networks Regulating Tissue Repair: Comparative Studies of Oral and Skin Wound Healing.

Wound repair is a systematic biological program characterized by four overlapping phases: hemostasis, inflammation, proliferation, and remodeling. Notwithstanding differences between species and distinct anatomical sites, the fundamental phases in the wound healing process are conserved among mammalian species. Oral wound healing is defined as an ideal wound healing model because it resolves rapidly and without scar formation.

The fate of patients with acute aortic syndrome during the coronavirus (COVID-19) pandemic: A UK multicenter study.

Objective: The coronavirus disease 2019 (COVID-19) pandemic has posed challenges to health care services across the world. There has been a significant restructuring of health care resources to protect services for patients with COVID-19-related illness and to maintain emergency and urgent medical and surgical activity. This study assessed access to emergency treatment, logistical challenges, and outcomes of patients with acute aortic syndrome during the early months of the COVID-19 pandemic in the United Kingdom.

Early experience of aortic surgery during the COVID-19 pandemic in the UK: A multicentre study.

Background: A significant restructuring of the healthcare services has taken place since the declaration of the coronavirus disease 2019 (COVID-19) pandemic, with elective surgery put on hold to concentrate intensive care resources to treat COVID-19 as well as to protect patients who are waiting for relatively low risk surgery from exposure to potentially infected hospital environment.

Methods: Multicentre study, with 19 participating centers, to define the impact of the pandemic on the provision of aortovascular services and patients' outcomes after having adapted the thresholds for intervention to guarantee access to treatment for emergency and urgent conditions. Retrospective analysis of prospectively collected data, including all patients with aortovascular conditions admitted for surgical or conservative treatment from the 1st March to the 20th May 2020.

Identifying English Practices that Are High Antibiotic Prescribers Accounting for Comorbidities and Other Legitimate Medical Reasons for Variation.

Background: Seeing one's practice as a high antibiotic prescriber compared to general practices with similar patient populations can be one of the best motivators for change. Current comparisons are based on age-sex weighting of the practice population for expected prescribing rates (STAR-PU). Here, we investigate whether there is a need to additionally account for further potentially legitimate medical reasons for higher antibiotic prescribing.

Hemoglobin A Accurately Predicts Continuous Glucose Monitoring-Derived Average Glucose in Youth and Young Adults With Cystic Fibrosis.

Objective: In cystic fibrosis (CF), hemoglobin A (HbA) is thought to underestimate glycemia. However, few studies have directly assessed the relationship between HbA and average glucose in CF. We determined the relationships among glycemic markers-HbA, fructosamine (FA), glycated albumin (%GA), and 1,5-anhydroglucitol (1,5-AG)-and continuous glucose monitoring (CGM) in CF, hypothesizing that alternate markers would better predict average sensor glucose (ASG) than HbA.
