Simulation program staff and leadership often struggle to partner with front-line healthcare workers, their managers, and health system leaders. Simulation-based learning programs are too often seen as burdensome add-ons rather than essential mechanisms supporting clinical workforce readiness. Healthcare system leaders grappling with declining morale, economic pressure, and too few qualified staff often don't see how simulation can help them, and we simulation program leaders can't seem to bridge this gap.

Stabilization of cereblon (CRBN)/neosubstrate complexes with molecular glues followed by degradation of those neosubstrates is an emerging strategy in drug discovery with compelling potential to target certain proteins that were previously considered to be undruggable. In this context, the discovery of novel CRBN ligands is an important area of ongoing research that holds promise to expand the scope of proteins that can be targeted through this mode of action. Herein, we describe the synthesis and evaluation of CRBN ligands featuring heteroaryl glutarimide and dihydrouracil scaffolds.

Gastrointestinal neuroendocrine tumors (GI-NETs) are rare neoplasms, with the gastric (stomach) subtype (G-NETs) representing a significant clinical focus. Type 1 G-NETs are particularly noteworthy due to their relationship with autoimmune atrophic gastritis (AAG) and pernicious anemia (PA), conditions that impact vitamin B12 absorption. This report presents the case of a patient with a type 1 G-NET identified at the initial diagnosis of PA, demonstrating the connection between these conditions.

Introduction: This study evaluates the clinical value of a deep learning-based artificial intelligence (AI) system that performs rapid brain volumetry with automatic lobe segmentation and age- and sex-adjusted percentile comparisons.

Methods: Fifty-five patients-17 with Alzheimer's disease (AD), 18 with frontotemporal dementia (FTD), and 20 healthy controls-underwent cranial magnetic resonance imaging scans. Two board-certified neuroradiologists (BCNR), two board-certified radiologists (BCR), and three radiology residents (RR) assessed the scans twice: first without AI support and then with AI assistance.

Article Synopsis
  • The mantellid subgenus Phylacomantis, comprising four frog species in Madagascar, is analyzed using molecular techniques to confirm their genetic distinctness and relationships based on nuclear and mitochondrial gene data.
  • The study reveals that G. pseudoasper shows low genetic variation across its range, while new specimens from the North East and North West have high genetic distances, suggesting they may belong to a new subspecies of G. corvus, named G. corvus bakilana ssp. nov.
  • The findings highlight a rare biogeographic pattern of separated sister lineages in Madagascar, indicating an urgent need for further research in the understudied humid forest fragments in the region.

Individuals with intestinal failure are at risk of micronutrient deficiencies, including iodine, an essential trace element critical for thyroid hormone production. In patients entirely dependent on parenteral nutrition, options for replenishing and maintaining iodine levels are severely restricted as oral forms have limited absorption, and intravenous alternatives are unavailable. Ethiodized oil (Lipiodol-TM) is an iodinated contrast agent with an unusually long half-life that can be given orally or injected into a target organ.

Article Synopsis
  • - The study examines the connection between cerebrovascular disease (CVD) biomarkers and amyloid beta (Aβ) in Alzheimer's disease (AD), finding that certain MRI-based biomarkers like white matter hyperintensities (WMHs) and superficial cerebral microbleeds (CMBs) are positively linked to Aβ positivity on PET scans.
  • - Using data from the Alzheimer's Disease Neuroimaging Initiative (ADNI), the researchers found that after adjustments, both WMHs and superficial CMBs significantly predicted Aβ-PET positivity, while deep CMBs and lacunes showed mixed results depending on cognitive subgroups.
  • - The research supports the use of CVD biomarkers for diagnosing AD and suggests the need for further investigation into

Background: Hypertension is a leading risk factor for cardiovascular disease among patients living with HIV (PLWH). Understanding the predictors and patterns of antihypertensive medication prescription and blood pressure (BP) control among PLWH with hypertension (HTN) is important to improve the primary prevention efforts for this high-risk population. We sought to assess important patient-level correlates (eg, race) and inter-facility variations in antihypertension medication prescriptions and BP control among Veterans living with HIV (VLWH) and HTN.

Introduction: Significant progress has been made in reducing maternal exposure to tobacco smoke and subsequent adverse birth outcomes, however, reductions may require strategies that reduce the availability of tobacco retailers. In this study, we investigated the relationship between tobacco retailer density and birth outcomes across the USA and predicted the potential impact of a tobacco retailer density cap on these outcomes.

Methods: Annual US county (n=3105), rates of preterm birth, low birth weight, small-for-gestational age, all-cause infant mortality and sudden infant death syndrome (SIDS) were calculated using National Vital Statistics System data.
