Hospital Health Information Exchange Network Density and Predictors Across U.S. Hospital Referral Regions.

Objective To develop a measure of Health Information Exchange (HIE) for characterizing the density of inter-hospital HIE connections and identify regional characteristics associated with HIE network density Materials and Methods HIE network density was measured as the proportion of hospital pairs within a region that are connected through HIE. The 2022 American Hospital Association's Information Technology Supplement survey was used to calculate HIE network density for US hospital referral regions (HRRs). Bivariate tests and multivariable regression were used to characterize hospital, electronic health record (EHR) vendor, and resident characteristics associated with HIE network density.

Evaluation of two MALDI-TOF MS systems and extraction methods for identification of filamentous fungi recovered from clinical specimens.

Unlabelled: Rapid and accurate identification of cultured molds is important to determine clinical significance and therapeutic decision-making. Conventional mold identification uses phenotypic macroscopic and microscopic characterization; however, this can take days or weeks for colony maturity and definitive microscopic structure formation, be limited to genus-level identification, and be misidentified due to morphologic mimics or similarities between closely related species. Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) revolutionized bacterial and yeast identification but remains uncommon for molds in part because of limited reference libraries.

Chronic traumatic brain injury induces neurodegeneration, neuroinflammation, and cognitive deficits in a T cell-dependent manner.

Traumatic brain injury (TBI) can lead to chronic neuroinflammation, and neurodegeneration associated with long-term cognitive deficits. Following TBI, the acute neuroinflammatory response involves microglial activation and the release of proinflammatory cytokines and chemokines which induce the recruitment of peripheral immune cells such as monocytes and ultimately T cells. Persistent innate and adaptive immune cells response can lead to chronic neurodegeneration and functional deficits.

Functional outcomes after ankle fracture-dislocation: a systematic review.

Introduction: Ankle fractures represent a significant portion of orthopedic injuries, with fracture dislocations tending to have worse outcomes. Logsplitter fractures represent a subset of fracture dislocations in which the talus is axially wedged in the tibiofibular joint. We aim to comprehensively investigate and report on the complications and functional outcomes associated with ankle fracture-dislocations.

Objective: To examine neuroanatomical features associated with early substance use initiation and to what extent associations may reflect preexisting vulnerability.

Design, Setting, And Participants: Cohort study using data from baseline through 3-year follow-up assessments of the ongoing longitudinal Adolescent Brain Cognitive Development Study.

Alcohol Use Disorder Polygenic Score Compared With Family History and ADH1B.

Importance: Identification of individuals at high risk of alcohol use disorder (AUD) and subsequent application of prevention and intervention programs has been reported to decrease the incidence of AUD. The polygenic score (PGS), which measures an individual's genetic liability to a disease, can potentially be used to evaluate AUD risk.

Objective: To assess the estimability and generalizability of the PGS, compared with family history and ADH1B, in evaluating the risk of AUD among populations of European ancestry.

Measuring Stigma in Pediatric Oncology: A Cross-Sectional Analysis of Three Global Sites.

Purpose: Stigma contributes to fear and shame, resulting in delays in care-seeking behavior among individuals with cancer. As a social construct, stigma is affected by language, religion, culture, and local norms. This study explored pediatric cancer stigma at the time of diagnosis across diverse settings through the adaptation of two stigma measures.

Lessons Learned from a Quality Improvement Initiative to Increase COVID-19 Vaccination in Hospitalized Children.

Introduction: Pediatric coronavirus disease 2019 (COVID-19) vaccination rates in the United States remain lower compared with adults. We aimed to (1) implement a quality improvement initiative to increase COVID-19 vaccination 2-fold in hospitalized patients 12-21 years of age from 4.7% during the baseline period (August 10, 2021-November 1, 2021) to 9.

Updated appropriate use criteria for amyloid and tau PET: A report from the Alzheimer's Association and Society for Nuclear Medicine and Molecular Imaging Workgroup.

Introduction: The Alzheimer's Association and the Society of Nuclear Medicine and Molecular Imaging convened a multidisciplinary workgroup to update appropriate use criteria (AUC) for amyloid positron emission tomography (PET) and to develop AUC for tau PET.

Methods: The workgroup identified key research questions that guided a systematic literature review on clinical amyloid/tau PET. Building on this review, the workgroup developed 17 clinical scenarios in which amyloid or tau PET may be considered.

Functional performance of patients with stroke during inpatient rehabilitation: a cross-sectional study of home and access visits.

Background: Home visits prior to inpatient rehabilitation facility (IRF) discharge allow occupational therapists to observe functional abilities among patients with stroke and address barriers that impact daily activities at home. However, home visits prior to IRF discharge are not standard practice due to barriers of time and cost constraints. We explored whether an access visit (visiting the home without the patient) could serve as an alternative to a home visit (with the patient) to anticipate functional abilities at home.

ENGAGE-TBI: adaptation of a community-based intervention to improve social participation after brain injury.

Background: Social isolation is prevalent after traumatic brain injury (TBI) and has negative implications for health and well-being. Interventions targeting social participation show promise for reducing social isolation. We adapted a social participation intervention, ENGAGE, to meet the needs of people with TBI.

Interleukin-1β Drives Disease Progression in Arrhythmogenic Cardiomyopathy.

Arrhythmogenic cardiomyopathy (ACM) is a genetic form of heart failure that affects 1 in 5000 people globally and is caused by mutations in cardiac desmosomal proteins including , and . Individuals with ACM suffer from ventricular arrhythmias, sudden cardiac death, and heart failure. There are few effective treatments and heart transplantation remains the best option for many affected individuals.

The uses of right heart catheterization in cardio-pulmonary disease: State-of-the-art.

The right heart catheterization (RHC) remains an important diagnostic tool for a spectrum of cardiovascular disease processes including pulmonary hypertension (PH), shock, valvular heart disease, and unexplained dyspnea. While it gained widespread utilization after its introduction, the role of the RHC has evolved to provide valuable information for the management of advanced therapies in heart failure (HF) and cardiogenic shock (CS) to name a few. In this review, we provide a comprehensive overview on the indications, utilization, complications, interpretation, and calculations associated with RHC.

Integrative multiomics reveals common endotypes across PSEN1, PSEN2, and APP mutations in familial Alzheimer's disease.

Background: PSEN1, PSEN2, and APP mutations cause Alzheimer's disease (AD) with an early age at onset (AAO) and progressive cognitive decline. PSEN1 mutations are more common and generally have an earlier AAO; however, certain PSEN1 mutations cause a later AAO, similar to those observed in PSEN2 and APP.

Methods: We examined whether common disease endotypes exist across these mutations with a later AAO (~ 55 years) using hiPSC-derived neurons from familial Alzheimer's disease (FAD) patients harboring mutations in PSEN1, PSEN2, and APP and mechanistically characterized by integrating RNA-seq and ATAC-seq.

CT Angiography of the Upper Extremities: Review of Acute Arterial Entities.

Capicua transcriptional repressor (CIC)-rearranged sarcoma (CRS) is a rare and recently described tumor that most commonly affects patients between 15 and 30 years of age. It is an undifferentiated round cell malignancy, with a disease defining CIC fusion, with double homeobox 4 (DUX4) being the most common partner. Here, we report a 77-year-old woman who presented with a cutaneous thigh mass with a clinical morphology suggesting Merkel cell carcinoma.

Associations Between Patient Characteristics and Progression to Multiple Myeloma Among Patients With Monoclonal Gammopathy of Undetermined Significance: A Systematic Review.

Monoclonal gammopathy of undetermined significance (MGUS) is a pre-malignant condition of multiple myeloma (MM). Evidence suggested old age, black race, male gender, and obesity as risk factors for MGUS development; however, whether they are associated with an increased risk of progression to MM among patients with MGUS is unclear. A systematic search of PUBMED and EMBASE for cohort studies investigating the association between age/race/gender/obesity and progression to MM.

Endothelial cell Piezo1 promotes vascular smooth muscle cell differentiation on large arteries.

Vascular stabilization is a mechanosensitive process, in part driven by blood flow. Here, we demonstrate the involvement of the mechanosensitive ion channel, Piezo1, in promoting arterial accumulation of vascular smooth muscle cells (vSMCs) during zebrafish development. Using a series of small molecule antagonists or agonists to temporally regulate Piezo1 activity, we identified a role for the Piezo1 channel in regulating klf2a, a blood flow responsive transcription factor, expression levels and altered targeting of vSMCs between arteries and veins.
