Education Research: Use by Neurologists of Microteaching and Microassessment Programs for Teaching, Learning, and Patient Care Needs: A Qualitative Study.

Background And Objectives: Microlearning is the acquisition of knowledge or skills in small units, commonly delivered by digital technology. NeuroBytes (NB) and Question of the Day (QOD) are 2 microinstructional programs in neurology. NB programs are brief, video-based mini-courses on clinical topics (microteaching); QODs are daily multiple-choice questions (microassessment).

Highly multiplexed imaging reveals prognostic immune and stromal spatial biomarkers in breast cancer.

Spatial profiling of tissues promises to elucidate tumor-microenvironment interactions and generate prognostic and predictive biomarkers. We analyzed single-cell, spatial data from three multiplex imaging technologies: cyclic immunofluorescence (CycIF) data we generated from 102 breast cancer patients with clinical follow-up, and publicly available imaging mass cytometry and multiplex ion-beam imaging datasets. Similar single-cell phenotyping results across imaging platforms enabled combined analysis of epithelial phenotypes to delineate prognostic subtypes among estrogen-receptor positive (ER+) patients.

Integration of Stromal Cells and Hydrogel Below Epithelium Results in Optimal Barrier Properties of Small Intestine Organoid Models.

: The barrier properties of the human small intestine play a crucial role in regulating digestion, nutrient absorption and drug metabolism. Current in vitro organotypic models consist only of an epithelium, which does not take into account the possible role of stromal cells such as fibroblasts or the extracellular matrix (ECM) which could contribute to epithelial barrier properties. Therefore, the aim of this study was to determine whether these stromal cells or ECM were beneficial or detrimental to barrier function when incorporated into an organotypic human small intestine model.

Expert consensus on the management of pharmacodynamic breakthrough-hemolysis in treated paroxysmal nocturnal hemoglobinuria.

Introduction: Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, acquired, non-malignant hematologic disease characterized by complement-mediated hemolysis (with or without hemoglobinuria), fatigue, increased susceptibility to thrombosis, and bone marrow dysfunction. The development of complement inhibitors has transformed outcomes for patients with PNH, but patients may still experience pharmacodynamic breakthrough hemolysis (BTH), which can be caused by exposure to a complement amplifying condition (CAC), such as vaccination, infection, or surgery.

Materials And Methods: A 13-member expert panel used a validated methodology (a RAND/UCLA modified Delphi panel) to develop consensus on how to classify pharmacodynamic BTH in patients with complement-inhibitor treated PNH.

Ex Vivo Human Tissue Functions as a Testing Platform for the Evaluation of a Nerve-Specific Fluorophore.

Significance: Selecting a nerve-specific lead fluorescent agent for translation in fluorescence-guided surgery is time-consuming and expensive. Preclinical fluorescent agent studies rely primarily on animal models, which are a critical component of preclinical testing, but these models may not predict fluorophore performance in human tissues.

Aim: The primary aim of this study was to evaluate and compare two preclinical models to test tissue-specific fluorophores based on discarded human tissues.
