Evaluating the Safety and Effectiveness of Regional Upper GI Bleed Services Through an Outcome-Based Analysis at a Centre in the United Kingdom.

Background The aim of this study was to compare the clinical characteristics and clinical outcomes of patients who presented with acute upper gastrointestinal bleeding (AUGIB) among two groups of patients who were transferred from local and district hospitals for endoscopy and subsequent management versus direct admissions to the emergency department with AUGIB to the Sheffield University Hospital NHS Trust. Methods We included 259 patients who underwent upper GI endoscopy from April 2018 to March 2022, of whom 29 were transferred and 230 were direct admissions. The analysis focused on demographics, pathological findings, time to endoscopy, blood transfusions, and hospital stay.

In Vivo Nerve-Specificity of Rhodamines and Si-rhodamines.

Accidental nerve damage or transection of vital nerve structures remains an unfortunate reality that is often associated with surgery. Despite the existence of nerve-sparing techniques, the success of such procedures is not only complicated by anatomical variance across patients but is also highly dependent on a surgeon's first-hand experience that is acquired over numerous procedures through trial and error, often with highly variable success rates. Fluorescent small molecules, such as rhodamines and fluoresceins have proven incredibly useful for biological imaging in the life sciences, and they appeared to have potential in illuminating vital nerve structures during surgical procedures.
