Traditional student evaluations of teaching and educator portfolios do not adequately assess the breadth and depth of medical educators' efforts. Current processes use limited perspectives, focus on a small portion of educators' work, and emphasize subjective opinions, which introduce bias. Use of these data for high-stakes decisions such as academic promotion contributes to inequitable career advancement.

Background: Clinical practice guidelines recommend that a kidney biopsy is no longer required to confirm a diagnosis of membranous nephropathy (MN) in patients with nephrotic syndrome and a positive test for anti-phospholipase A2 receptor antibodies (PLA2R-Ab). However, the optimal diagnostic strategy for using the PLA2R-Ab enzyme-linked immunosorbent assay (ELISA), PLA2R-Ab indirect immunofluorescence (IIF) test, and genetic risk score for diagnosing MN, including the tests' optimal thresholds for positivity among incident patients with proteinuria, is still unknown.

Methods: We used serum samples at or before the first clinically indicated kidney biopsy from participants in the Nephrotic Syndrome Study Network (NEPTUNE) to analyze test performance characteristics using different combinations and cut-offs of the PLA2R-Ab ELISA, IIF, and genetic risk score for diagnosing MN.

Single-cell and spatial genomic landscape of non-small cell lung cancer brain metastases.

Nat Med

February 2025

Division of Hematology/Oncology, Department of Medicine, Vagelos College of Physicians and Surgeons, Columbia University Irving Medical Center, New York, NY, USA.

Brain metastases frequently develop in patients with non-small cell lung cancer (NSCLC) and are a common cause of cancer-related deaths, yet our understanding of the underlying human biology is limited. Here we performed multimodal single-nucleus RNA and T cell receptor, single-cell spatial and whole-genome sequencing of brain metastases and primary tumors of patients with treatment-naive NSCLC. Chromosomal instability (CIN) is a distinguishing genomic feature of brain metastases compared with primary tumors, which we validated through integrated analysis of molecular profiling and clinical data in 4,869 independent patients, and a new cohort of 12,275 patients with NSCLC.

Silvestri, MD, MBA, MHS, is Assistant Vice President of Emergency Management, NYC Health + Hospitals, New York, NY. R. James Salway, MD, MSc, is an Assistant Professor of Emergency Medicine, Weill Cornell School of Medicine, New York, NY.

When patient demand exceeds hospital capacity in certain scenarios, such as natural disasters, terrorist attacks, or staffing shortages, the rapid discharge of patients identified through reverse triage methodologies can create surge capacity. The evaluation of this concept has been documented in numerous resources and studies, but current tools tend to be extensive and siloed, which may make them difficult to use during emergencies. To prepare the largest municipal healthcare system in the United States for situations requiring rapid patient discharge, NYC Health + Hospitals/Central Office Emergency Management sought to develop a short, synthesized, and user-friendly plan.

Cerebellar ataxia results from various genetic and nongenetic disorders and is characterized by involuntary movements that impair precision and motor rhythm. Here, we report that climbing fiber (CF) denervation is a common pathophysiology underlying motor rhythm loss in cerebellar ataxia. By examining cerebellar pathology in patients with spinocerebellar ataxia (SCA) types 1, 2, and 6 and multiple system atrophy, we identified CF degeneration with synaptic loss as a shared pathophysiology.

Recent studies show that systemic administration of a glucagon-like peptide-1 receptor (GLP-1R) agonist is sufficient to attenuate cocaine seeking. However, the neural mechanisms mediating these effects and the role of endogenous central GLP-1 signaling in cocaine seeking remain unknown. Here, we show that voluntary cocaine taking decreased plasma GLP-1 levels in rats and that chemogenetic activation of GLP-1-producing neurons in the nucleus tractus solitarius that project to the ventral tegmental area (VTA) decreased cocaine seeking.

Introduction: Educational attainment is associated with midlife cognitive functioning. However, degree attainment is the culmination of complex and unequal processes involving students' backgrounds, the opportunities that schools provide them, and their performance within those schools─all of which may also shape midlife cognition. What do educational gradients in midlife cognition look like using a richer conceptualization and measures of "education?"

Methods: We use data from High School and Beyond (HS&B:80)─a large, nationally representative sample of Americans followed from high school through age ∼60─to assess the role of education in stratifying midlife cognition.
