Frozen Section Doughnuts Obtained with a 5 mm Stapling Device Improve Outcomes in Laparoscopic Endorectal Pull-Throughs for Hirschsprung's Disease.

A primary pull-through for Hirschsprung's disease (HD) requires confirmation of normal ganglionic bowel by intraoperative biopsies to determine the level of resection. Despite this, aganglionic bowel that is not fully resected (so-called "transition zone pull-throughs") is reported in 15%-19% of patients. We hypothesize that this may result from insufficient biopsies sent for intraoperative diagnosis.

Affinity maturation endows potent activity onto class 6 SARS-CoV-2 broadly neutralizing antibodies.

The emergence of SARS-CoV-2 variants of concern (VOCs) has greatly diminished the neutralizing activity of previously FDA-approved monoclonal antibodies (mAbs), including that of antibody cocktails and of first-generation broadly neutralizing antibodies such as S309 (Sotrovimab). In contrast, antibodies targeting cryptic conformational epitopes of the receptor binding domain (RBD) have demonstrated broad activity against emerging variants, but exert only moderate neutralizing activity, which has so far hindered clinical development. Here, we utilize in vitro display technology to identify and affinity-mature antibodies targeting the cryptic class 6 epitope, accessible only in the "up" conformation of the SARS-CoV-2 spike trimer.

Benefit of Avasopasem Manganese on Severe Oral Mucositis in Head and Neck Cancer in the ROMAN Trial: Unplanned Secondary Analysis.

Purpose: Oral mucositis (OM) is a debilitating side effect of cisplatin and intensity-modulated radiation therapy (IMRT) in patients with head and neck cancer. The phase 3 ROMAN trial showed avasopasem manganese (AVA) significantly decreased individual endpoints of incidence and duration of severe oral mucositis (SOM, World Health Organization [WHO] grade 3-4), with nominal decrease in severity (WHO grade 4) and significant increase in the delay in onset of SOM. We sought to determine the Net Treatment Benefit (NTB) of AVA versus placebo (PBO) using the generalized pairwise comparisons (GPC) method.

Evaluating Instructor Feedback Practices in a Clinical Learning Environment in a Developing World Setting; a Qualitative Study.

Background: Feedback is an essential component in medical education. Delivering timely and relevant feedback to individual students enhances workplace-based learning. There is increasing evidence that current feedback practices are not fit for purpose.
