Management Patterns and Outcomes of Vestibular Schwannoma in Older Adults: Assessment of the SEER Database

OBJECTIVE: Vestibular schwannoma (VS) is a benign intracranial tumor that is increasingly diagnosed in older adults. The relative contributions of tumor burden and surgical management to overall survival in elderly and very elderly patients remain incompletely characterized at a...

Study protocol for first national vasa previa perinatal registry

Vasa previa is a rare but potentially catastrophic obstetric condition characterized by unprotected fetal blood vessels over or adjacent to the internal cervical os. Although advances in prenatal ultrasound have dramatically improved neonatal survival through planned cesarean del...

Laser Interstitial Thermal Therapy for Brain Tumors: A Prospective Multicenter Analysis of Patients From the LAANTERN Study

Background: Laser interstitial thermal therapy is a surgical tool used to ablate brain tumors, radiation necrosis, and epileptic foci. Data from the completed LAANTERN prospective multicenter registry (NCT02392078), containing tumor patients enrolled in the study across 25 US cen...

Towards unified AI-driven fracture mechanics: the extended deep energy method (XDEM)

Abstract Physics-Informed Neural Networks (PINNs) have recently emerged as powerful tools for solving partial differential equations (PDEs), with the Deep Energy Method (DEM) proving especially effective in fracture mechanics due to its energy-based formulation. Despite these adv...

Association Between Changes in Perceived Neighborhood and Cognitive Performance Within Healthy Aging in Neighborhoods of Diversity Across the Life Span (HANDLS) Black Adults

Perceived neighborhood characteristics are related to cognitive performance. However, limited studies have examined how changes in neighborhood characteristics relate to cognitive performance, particularly among Black adults who are likely to experience changes in their residenti...

The Shadow of Your Law and the Judge Over Your Shoulder

ABSTRACT Many problems in public policy and delivery which are otherwise difficult to understand, make much more sense when viewed as strategies for the management of legal risk. Civil servants, infrastructure developers and other parties who are subject to the risk of legal revi...

Vision-Language Model as a ‘Zero-Shot’ Assistant for Evaluating Condylar Osseous Changes in Cone-beam Computed Tomography

INTRODUCTION AND AIMS: Interpreting condylar osseous changes on CBCT is challenging for general practitioners. This study evaluated the 'zero-shot' diagnostic performance and utility of Vision-Language Models (VLMs) as AI assistants for detecting condylar abnormalities. METHODS:...

Acceptability and Feasibility of a Primary Care Hypoglycemia Prevention Program: A Pilot Study

OBJECTIVE Hypoglycemia, a major cause of morbidity for people with diabetes, is underrecognized in primary care, leading to underuse of risk mitigation strategies. This study reports the development and acceptability/feasibility testing of the Hypoglycemia Prevention Program (HPP...

The hematology workforce in the United States: past, present, and strategies for the future

From 2017-2021, the American Society of Hematology (ASH) completed the largest study ever conducted of the hematology workforce in the United States (US). The study highlighted a deficit in the classical hematology (CH) workforce: despite very high CH clinical volumes encountered...

ARport: an augmented reality system for markerless image-guided port placement in robotic surgery

Abstract Purpose Precise port placement is a critical step in robot-assisted surgery, where port configuration influences both visual access to the operative field and instrument maneuverability. To bridge the gap between preoperative planning and intraoperative execution, we pre...

Lipid-Rich Urothelial Carcinoma

Lipid-rich urothelial carcinoma (LR-UC) is a rare subtype, with ∼65 cases reported in the literature. Here, we report the largest case series of bladder LR-UC, including 40 patients. Clinical follow-up was available for 29 patients. Twenty-seven patients had at least 2-years foll...

The extreme diversity of retinal amacrine cells has deep evolutionary roots

Amacrine cells (ACs) comprise a heterogeneous class of inhibitory neurons in the vertebrate retina, exhibiting morphological and functional complexity rivaling that of cortical interneurons. Here, we integrate single-cell and single-nucleus transcriptomic atlases from 24 vertebra...

Perspectives on Drug Treatment Among Indigenous Peoples in Recovery Residing in the Northern Midwest United States

Objective: Evidence-based drug treatment is a vital component of an effective response to substance use inequities in the United States (US). Unfortunately, many drug treatment models were developed in western contexts and may fail to account for Indigenous cultures and values. T...

Psychoactive Medication Prescribing After Critical Illness in American Adults Not Justified by a Documented Supporting Diagnosis

Objectives: To describe psychoactive medication (PM) prescribing in the 30 days after an ICU admission requiring mechanical ventilation not supported by a documented diagnosis in American adults not prescribed a PM before ICU admission. This nondiagnostically supported PM prescri...

Hypothalamic prolactin receptor+ dopaminergic neurons regulate energy metabolism and nociceptive threshold in mice during lactation

Women during lactation undergo significant bone loss and metabolic changes. However, the underlying mechanisms in the brain remain unclear. Herein, we found that prolactin receptor (PRLR)+ neurons in the hypothalamus control lactation physiology and metabolism in mice. Prolactin...

Phong‐Rodrigues Extrinsic Vector‐Field Processing

Abstract We introduce a new extrinsic discretization of tangent vector fields on triangle meshes that is continuous, with bounded derivatives that are continuous almost everywhere, supporting pointwise evaluation and integration of differential operators. We achieve this by build...

Single-cell profiling of peripheral blood mononuclear cells in diverse men with prostate cancer reveals a fatal disease-associated immune signature

Abstract Alterations in peripheral immunity may contribute to fatal prostate cancer and the excessive disease burden among African American (AA) men. Thus, we investigated peripheral immunity in prostate cancer patients in association with disease outcome and AA descent. We perfo...

Nucleosomes and IDRs suppress promiscuous GCN4 binding on minichromosomes

Abstract Eukaryotic sequence-specific transcription factors (TFs) must find their cognate DNA targets hidden in genomic chromatin amid an excess of nonspecific sequences and degenerate motifs. Although static TF interactions with nucleosomal targets have been elucidated, how TFs...

Translational insights and clinical challenges of targeting cancer stem cells

Abstract Cancer stem cells (CSCs) are tumor cell subsets with self-renewal, multilineage differentiation, and tumor-initiating capacity that sustain cancer initiation, progression, metastasis, and relapse. Targeting CSCs therefore represents a promising route to improve the durab...

An analysis of educational sector mixing among US homeschooling families from three waves of the national household education survey

Conceptual frameworks and policies about homeschooling often assume that families homeschool either all or none of their children because the decision to homeschool is based on the belief that homeschooling is the normative means to educate one’s children. Thus, the practice of s...
