Basic Science and Pathogenesis.

Background: Alzheimer's disease (AD) pathology can start accumulating 20-30 years before cognitive symptoms occur, with increases in inflammation, amyloid-β (Aβ), and hyperphosphorylated Tau during this time. Previous studies have shown that the post-translational modification of a single N-acetylglucosamine moiety to serine or threonine residues to cytosolic or nuclear proteins, known as O-GlcNAcylation, can modify a plethora of cellular processes, including the processing of the amyloid precursor protein, competing with phosphorylation on tau, as well as having anti-inflammatory effects. This study is designed to evaluate how increasing O-GlcNAcylation is impacting AD pathology in the most comprehensive AD rat model to date, the TgF344-AD rat model.

Replication Kinetics, Pathogenicity and Virus-induced Cellular Responses of Cattle-origin Influenza A(H5N1) isolates from Texas, United States.

The host range of HPAIV H5N1 was recently expanded to include ruminants, particularly dairy cattle in the United States (US). Shortly after, human H5N1 infection was reported in a dairy worker in Texas following exposure to infected cattle. Herein, we rescued the cattle-origin influenza A/bovine/Texas/24-029328-02/2024(H5N1, rHPbTX) and A/Texas/37/2024(H5N1, rHPhTX) viruses, identified in dairy cattle and human, respectively, and their low pathogenic forms, rLPbTX and rLPhTX, with monobasic HA cleavage sites.

Type 1 Immune Responses Related to Viral Infection Influence Corticosteroid Response in Asthma.

Rationale: Corticosteroid-responsive type 2 (T2) inflammation underlies the T2-high asthma endotype. However, we hypothesized that type 1 (T1) inflammation, possibly related to viral infection, may also influence corticosteroid response.

Objectives: To determine the frequency and within-patient variability of T1-high, T2-high, and T1/T2-high asthma endotypes and whether virally influenced T1-high disease influences corticosteroid response in asthma.

Surfactant Protein A Inhibits Human Rhinovirus C Binding and Infection of Airway Epithelial Cells from Pediatric Asthma.

Rhinovirus C (RV-C) infection can trigger asthma exacerbations in children and adults, and RV-C-induced wheezing illnesses in preschool children correlate with the development of childhood asthma. Surfactant protein A (SP-A) plays a critical role in regulating pulmonary innate immunity by binding to numerous respiratory pathogens. Mature SP-A consists of multiple isoforms that form the hetero-oligomers of SP-A1 and SP-A2, organized in 18-mers.

Social media in pathology and laboratory medicine: A systematic review.

The use of social media platforms in pathology and medical laboratory science has increased in recent years, revolutionizing the way professionals in these fields interact, disseminate information, and collaborate. To gain an understanding of the current landscape regarding social media use in pathology and medical laboratory science, a novel systematic review was conducted. A search of PubMed, Medline, Embase, and Scopus was performed to identify articles evaluating social media use within pathology and medical laboratory science.

Burnout and Turnover Among Veterans Health Administration Primary Care Providers From Fiscal Years 2017-2021.

Objectives: We examined how individual-level turnover among Veterans Health Administration primary care providers (PCPs) from fiscal years 2017 to 2021 was associated with health care system-level burnout and turnover intent.

Background: Burnout among PCPs has been well documented in recent studies, but less is known about the potential relationship between burnout and turnover.

Methods: We identified a national cohort of 6444 PCPs (physicians, nurse practitioners, and physician assistants) in 129 Veterans Health Administration health care systems in the first quarter of fiscal year 2017 and tracked their employment status for 20 quarters.

A Polyimide Composite-Based Electromagnetic Cantilever Structure for Smart Grid Current Sensing.

Polyimides (PIs) have been extensively used in thin film and micro-electromechanical system (MEMS) processes based on their excellent thermal and mechanical stability and high glass transition temperature. This research explores the development of a novel multilayer and multifunctional polymer composite electro-piezomagnetic device that can function as an energy harvester or sensor for current-carrying wires or magnetic field sensing. The devices consist of four layers of composite materials with a polyimide matrix.

Tobacco consumption behavior change during the COVID-19 pandemic is associated with perceived COVID threat.

Rationale: Tobacco use is a risk factor for COVID-19 adverse outcomes. Despite health implications, data conflict regarding COVID-19 and tobacco consumption. We present results from a survey of health behaviors during the pandemic to identify how COVID-19 influenced tobacco behaviors.

Implementation lessons learned from the University of California's Diabetes Prevention Program Initiative.

Background: The University of California's Diabetes Prevention Program (UC DPP) Initiative was implemented systemwide to address diabetes and obesity risk on all 10 campuses. As little is known about implementing lifestyle change programs in university settings, we examined implementation partners' (i.e.

Sinoatrial node function and the role of sinoatrial conduction in the typical atrial flutter substrate.

Background: Sinoatrial node (SAN) activation and sinoatrial conduction pathways (SACPs) have been assessed in animals but not in humans.

Objectives: We used ultrahigh-density mapping and simulated models to characterize the SAN and to investigate whether slowed SAN conduction may contribute to the atrial flutter (AFL) substrate.

Methods: Twenty-seven patients undergoing electrophysiologic procedures had right atrial mapping.

Chemically Transferable Electronic Coarse Graining for Polythiophenes.

Recent advances in machine-learning-based electronic coarse graining (ECG) methods have demonstrated the potential to enable electronic predictions in soft materials at mesoscopic length scales. However, previous ECG models have yet to confront the issue of chemical transferability. In this study, we develop chemically transferable ECG models for polythiophenes using graph neural networks.

Cellular N-Myristoyl Transferases Are Required for Mammarenavirus Multiplication.

The mammarenavirus matrix Z protein plays critical roles in virus assembly and cell egress. Meanwhile, heterotrimer complexes of a stable signal peptide (SSP) together with glycoprotein subunits GP1 and GP2, generated via co-and post-translational processing of the surface glycoprotein precursor GPC, form the spikes that decorate the virion surface and mediate virus cell entry via receptor-mediated endocytosis. The Z protein and the SSP undergo N-terminal myristoylation by host cell N-myristoyltransferases (NMT1 and NMT2), and G2A mutations that prevent myristoylation of Z or SSP have been shown to affect the Z-mediated virus budding and GP2-mediated fusion activity that is required to complete the virus cell entry process.

Association of non-English language preference with postoperative hospital visits among California Medicaid enrollees.

Background: Patients with non-English language preference encounter language barriers across phases of surgical care. Patients with a non-English language preference represent 35% of California households and are disproportionately insured by Medicaid. To determine whether language predicts surgical outcomes, we investigated the association of patient non-English language preference with postoperative emergency department visits and readmissions among California Medicaid enrollees.

Justice-Involved Youth: Support for Community and Family Interventions.

Justice-involved youth have high rates of mental health symptoms and diagnoses. Unaddressed mental health needs are associated with exposure to adversity and trauma, as well as unidentified or mislabeled symptoms that may be present early in life. Justice-involved youth disproportionately come from low-income families and minoritized populations.

Determinants to Tele-Mental Health Services Utilization Among California Adults: Do Immigration-Related Variables Matter?

To investigate the relationship of predisposing, enabling, need, and immigration-related factors to tele-mental health services utilization among California adults, we conducted a secondary analysis of two waves of the California Health Interview Survey (CHIS) collected between 2015 and 2018 (N = 78,345). A series of logistic regression models were conducted to examine correlates and predictors to tele-mental health services use. Approximately 1.

Manual Chest PRESSURE During Direct Current Cardioversion for Atrial Fibrillation: A Randomized Control Trial (PRESSURE-AF).

Background: Direct current cardioversion is frequently used to return patients with atrial fibrillation (AF) to sinus rhythm. Chest pressure during cardioversion may improve the efficacy of cardioversion through decreasing transthoracic impedance and increasing cardiac energy delivery.

Objectives: This study aimed to assess the efficacy and safety of upfront chest pressure during direct current cardioversion for AF with anterior-posterior pad positioning.

Fasting vs. no fasting prior to catheterization laboratory procedures: the SCOFF trial.

Background And Aims: Current guidelines recommend 6 h of solid food and 2 h of clear liquid fasting for patients undergoing cardiac procedures with conscious sedation. There are no data to support this practice, and previous single-centre studies support the safety of removing fasting requirements. The objective of this study was to determine the non-inferiority of a no-fasting strategy to fasting prior to cardiac catheterization procedures which require conscious sedation.
