Implementation of a pilot online educational program to identify paramagnetic rim lesions

Background: Paramagnetic rim lesions are a highly specific magnetic resonance imaging biomarker for multiple sclerosis now incorporated into the 2024 McDonald Criteria. However, paramagnetic rim lesion identification remains underutilized in clinical practice. This study evaluate...

Addressing Common Problems in Autism Research: Cohort Development and Sample Description for a Participatory, Real-World, Longitudinal Study of Outcomes in Autistic Adults

Adult autism services research is plagued by methodological challenges, including difficulty obtaining representative or heterogeneous samples and a frequent mismatch between experimental methodologies and real-world settings. The Academic Autism Spectrum Partnership in Research...

P1.199. Preoperative Frailty Testing for Esophagectomy: Stair-Climb Time as the Strongest Predictor of Major Complications

Abstract Topic Esophageal Cancer: Surgical Treatment of Esophageal Cancer – early outcomes and complications Background Esophageal cancer is increasingly common in an aging population. Esophagectomy remains a cornerstone of treatment but carries substantial perioperative risk. Ac...

Dental Students' Use of Captions and Transcripts: Implications for ADA WCAG 2.1 Compliance

OBJECTIVES: This study examined how Doctor of Dental Medicine (DMD) students use captions and transcripts, their motivations for use, and their perceived learning benefits, with attention to accessibility and upcoming ADA compliance requirements. METHODS: A cross-sectional, anony...

Changes in Emergency Department Pediatric Readiness, Inpatient Services, and Excess Child Deaths

Importance Emergency department (ED) pediatric readiness and pediatric inpatient services have changed over time in many hospitals, but the impact of these changes on pediatric outcomes is unclear. Objective To evaluate pediatric mortality associated with changes to ED pediatric...

Plectin promotes an aggressive phenotype and represses cytotoxic T cell activity in pancreatic cancer

Abstract Background Pancreatic adenocarcinoma (PDAC) is an abysmal disease, with a poor clinical outcome, largely due to limited life-extending treatments for patients. Notoriously, PDAC displays a T cell-suppressive tumor microenvironment where underlying molecular mechanisms th...

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...

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...

Hepatic stellate cell activation in the postpartum liver is consistent with pre-metastatic niche establishment

Postpartum breast cancer (PPBC), diagnosed within 10 years of the last childbirth, has an increased risk of liver metastasis. In murine models, tumor transplant studies reveal that weaning-induced liver involution is a key determinant of breast cancer metastasis to the liver. Her...

Genomic catalogue of giant viruses reveals expanded diversity and functional potential

Nucleocytoplasmic large DNA and Mirusviricota viruses exhibit taxonomic richness which continually expands due to metagenomic sequencing. Here we curate a database of giant virus metagenome-assembled genomes (GVMAGs V2), comprising 8,508 species-level representatives from 18,727...

Stereotactic Body Radiotherapy vs Moderately Hypofractionated IMRT for Localized Intermediate-Risk Prostate Cancer

Importance The treatment of prostate cancer with radiotherapy is evolving. How quickly radiotherapy can be delivered, and the relative risks and benefits of such a treatment, is of significant public interest. Objective To determine whether stereotactic body radiotherapy (SBRT) w...

suPAR Identifies Treatment-Resistant Inflammatory Risk Beyond hs-CRP in Type 2 Diabetes With Coronary Artery Disease: An Ancillary Analysis of BARI 2D

OBJECTIVE To determine whether soluble urokinase plasminogen activator receptor (suPAR) is modified by randomized diabetes and revascularization strategies in patients with type 2 diabetes and coronary artery disease and whether combined suPAR and hs-CRP classification refines re...

Spatial organization of the tumor-immune microenvironment in ER-positive breast cancer with treatment remodeling and associated clinical responses

The tumor microenvironment influences treatment response in ER-positive breast cancer, but what distinguishes responders from non-responders and how it changes during treatment is poorly understood. Here, we profiled ER-positive breast tumors treated with neoadjuvant chemotherapy...

Examining the Sustained Impact of California’s Tobacco Free for Recovery Initiative: Qualitative Perspectives from Program Directors

Background: Smoking prevalence among people in substance use treatment is substantially higher than the national average. Residential substance use treatment represents an opportune time to address this disparity. California launched the Tobacco Free for Recovery Initiative to he...

Pyramidal cell types and circuit organization of the mouse insular cortex reveal functional specializations

Abstract The insular cortex integrates interoceptive and exteroceptive information to mediate bodily homeostasis, emotion and learning. However, the cellular and circuit substrates governing insular functions are poorly understood compared to primary cortices. Here we quantify de...

Pregnancy Ambivalence, History of Pregnancy, Condom Use, and Contraceptive Use Among U.S. Youth Experiencing Homelessness

Youth experiencing homelessness (YEH) are 5–8 times more likely than housed peers to become pregnant. A more nuanced examination of YEH pregnancy desire may better inform pregnancy and pregnancy prevention guidance. This study examined pregnancy ambivalence, pregnancy history, co...

Telemedicine Use in Primary Care for Children: 2019–2024

BACKGROUND AND OBJECTIVES We lack national data on the maturing clinical use of telemedicine (TM) in children’s primary care. This manuscript describes patterns of TM use for problem-based visits overall, across clinical domains, and associations of use with clinic visit volume....

A cross-national study examining social determinant factors on short sleep between the U.S. and Canada

Sleep is essential for optimal health as short sleep is associated with cardiovascular disease, diabetes, and early mortality. One-third of adults in the U.S. and Canada do not receive sufficient sleep. Canadian adults are typically healthier than U.S. adults and inequities in sl...

Duration of Therapeutic Hypothermia After Out-of-Hospital Cardiac Arrest

Importance Therapeutic hypothermia is widely used for neuroprotection following cardiac arrest, but clinical trials have not consistently demonstrated improved neurological outcomes, and the optimal duration of cooling remains uncertain. Objective To determine the duration of the...

A compendium of next-generation patient-derived models for diverse cancers

Abstract The development of new therapeutics and the validation of pathogenetic cancer mechanisms require representative laboratory models 1,2 . However, existing collections represent only a fraction of the diversity observed in human cancer 2–4 . Recent technologies have enable...
