We investigated Aβ in gingiva, serum or hippocampus and neurovascular reactivity in basilar artery (BA) of periodontitis rats, to test the impact of Aβ on BA vasoreactivity ex vivo.

Materials And Methods: Periodontitis was induced in 32 rats using silk-ligation.

Efficacy and safety of iclepertin (BI 425809) with adjunctive computerized cognitive training in patients with schizophrenia.

Unlabelled: Despite significant patient burden, there are no approved pharmacotherapies to treat symptoms of cognitive impairment associated with schizophrenia (CIAS). This double-blind, placebo-controlled, parallel-group Phase II trial assessed the efficacy and safety of pharmacological augmentation of at-home computerized cognitive training (CCT) with iclepertin (BI 425809, a glycine transporter-1 inhibitor). Participants with schizophrenia (aged 18-50 years) on stable antipsychotic therapy, who were compliant with CCT during the run-in period, were enrolled.

Engineering extracellular vesicles for targeted therapeutics in cardiovascular disease.

Extracellular vesicles (EVs) are nanosized particles secreted by cells that play crucial roles in intercellular communication, especially in the context of cardiovascular diseases (CVDs). These vesicles carry complex cargo, including proteins, lipids, and nucleic acids, that reflects the physiological or pathological state of their cells of origin. Multiomics analysis of cell-derived EVs has provided valuable insights into the molecular mechanisms underlying CVDs by identifying specific proteins and EV-bound targets involved in disease progression.

Assessing law enforcement officer skills in Crisis Intervention Team (CIT) research: developing and implementing standardized scenarios.

This paper outlines the development of standardized scenarios used to assess the efficacy of Crisis Intervention Team (CIT) training in a randomized, controlled trial. The objective was to create scenarios that accurately simulate mental health crisis situations for law enforcement officers, ensuring that each scenario tests specific CIT skills relevant to real-world encounters. Our process involved building an interdisciplinary team and drawing from the knowledge and experience of professionals in law enforcement, mental health, and performance arts to design a set of scenarios that are both realistic and challenging.

Kidney Function Decline After COVID-19 Infection.

Biocompatible TA4 and TC4ELI with excellent mechanical properties and corrosion resistance via multiple ECAP.

Titanium (Ti), characterized by its exceptional mechanical properties, commendable corrosion resistance and biocompatibility, has emerged as the principal functional materials for implants in biomedical and clinical applications. However, the Ti-6Al-4V (TC4ELI) alloy has cytotoxicity risks, whereas the strength of the existing industrially pure titanium TA4 is marginally inadequate and will significantly limit the scenarios of medical implants. Herein, we prepared ultrafine-grained industrial-grade pure titanium TA4 and titanium alloy TC4ELI via the equal channel angular pressing method, in which the TA4-1 sample has ultrahigh strength of 1.

Kidney Function, Kidney Function Decline, and the Risk of Abdominal Aortic Aneurysm: The Stockholm CREAtinine Measurements (SCREAM) Project.

Objective: Low estimated glomerular filtration rate (eGFR) increases the risk of arterial diseases, possibly including abdominal aortic aneurysm (AAA). This study explored the relationship between eGFR (2008 CKD-EPI equation), annual eGFR decline, and subsequent risk of developing AAA in a large, community based sample.

Methods: This was an observational study using complete healthcare records of Stockholm residents free from AAA who underwent routine creatinine testing during 2011 - 2021.

Impact of arteriovenous fistula formation on trajectory of kidney function decline: a target trial emulation.

Background: Prior nonrandomized studies have suggested nephroprotective effects of arteriovenous fistula (AVF) formation, but these are plausibly susceptible to immortal time and selection biases.

Methods: We studied patients attending nephrology clinics in the West of Scotland during 2010-22 with an estimated glomerular filtration rate (eGFR) ≤15 mL/min/1.73 m and no prior AVF.

External validation of EuroSCORE I and II in patients with infective endocarditis: results from a nationwide prospective registry.

Objectives: The primary objective was to externally validate EuroSCORE I and II in surgically treated endocarditis patients. The secondary objective was to assess the predictive performance of both models across sex, redo surgery, age, and urgency.

Methods: Data were retrieved from the Netherlands Heart Registration.

Home Sotalol Initiation for the Management of Atrial and Ventricular Arrhythmias Using Remote Electrocardiographic Monitoring.

Background: Sotalol is a class III antiarrhythmic drug used for the management of patients with atrial fibrillation to maintain sinus rhythm. Sotalol-induced QT interval prolongation can be proarrhythmic and is conventionally initiated in an inpatient setting where routine electrocardiographic (ECG) monitoring is available while sotalol reaches the steady state. The emergence of cellular-compatible home ECG devices, such as AliveCor's Kardia Mobile 6L, which offers 6-lead ECG, has made it possible to accurately measure QT intervals outside the hospital.

Acceptability of a Fresh Produce Intervention for Individuals With Serious Mental Illnesses.

Objective: To qualitatively evaluate the acceptability and end-user perspectives of a 3-component Fresh Produce and Healthy Eating intervention seeking to increase fruit and vegetable consumption among individuals with serious mental illnesses (SMI) in residential settings.

Methods: Twenty-seven interviews were conducted with housing residents with SMI, curriculum instructors, agency leadership, and mobile market staff. Interviews were analyzed using thematic analysis.

A Review of Human Papillomavirus Vaccination and Associated Ethical Concerns.

Since its Fast-Track approval by the Federal Drug Administration, the human papillomavirus (HPV) vaccine has been marked by controversies. Unconfirmed reports of adverse events in both Japan and Denmark led to suspensions of national vaccination programs, which setback the fight against cervical cancer and associated mortality and morbidity. Despite follow-up studies of vaccine adverse reports, additional randomized control trials, and review reports from both the World Health Organization and the European Commission, there is still a great deal of hesitancy around the vaccine.

Systemic inflammation and health outcomes in patients receiving treatment for atherosclerotic cardiovascular disease.

Background And Aims: The burden and outcomes of inflammation in patients with atherosclerotic cardiovascular disease (ASCVD) are not well defined beyond the controlled settings of trials and research cohorts.

Methods: This was an observational study of ASCVD adults undergoing C-reactive protein testing in Stockholm's healthcare (2007-21). After excluding C-reactive protein tests associated with acute illness or medications/conditions that bias C-reactive protein interpretation, systemic inflammation was evaluated over a 3-month ascertainment window.

Decoy receptors as biomarkers for exploring aetiology and designing new therapies.

Soluble decoy receptors (DR) are circulating proteins that act as molecular traps for ligands that modulate various signalling pathways. These proteins can be exploited as biomarkers and, in some cases, as drugs in various disease contexts. Inflammation is a key area where DRs have shown significant potential.

GLP-1RA vs DPP-4i Use and Rates of Hyperkalemia and RAS Blockade Discontinuation in Type 2 Diabetes.

Importance: Hyperkalemia is a common complication in people with type 2 diabetes (T2D) that may limit the use of guideline-recommended renin-angiotensin system inhibitors (RASis). Emerging evidence suggests that glucagon-like peptide-1 receptor agonists (GLP-1RAs) increase urinary potassium excretion, which may translate into reduced hyperkalemia risk.

Objective: To compare rates of hyperkalemia and RASi persistence among new users of GLP-1RAs vs dipeptidyl peptidase-4 inhibitors (DPP-4is).

Integrated transcriptomic and proteomic analyses reveal the effects of chronic benzene exposure on the central nervous system in mice.

Benzene exposure is known to cause serious damage to the human hematopoietic system. However, recent studies have found that chronic benzene exposure may also cause neurological damage, but there were few studies in this issue. The aim of this study was to investigate the mechanism of damage to the central nervous system (CNS) by chronic benzene exposure with a multi-omics analysis.

PGC-1α agonism induces fetal hemoglobin and exerts antisickling effects in sickle cell disease.

Sickle cell disease is a growing health burden afflicting millions around the world. Clinical observation and laboratory studies have shown that the severity of sickle cell disease is ameliorated in individuals who have elevated levels of fetal hemoglobin. Additional pharmacologic agents to induce sufficient fetal hemoglobin to diminish clinical severity is an unmet medical need.

Biomimetic Supramolecular Assembly with IGF-1C Delivery Ameliorates Inflammatory Bowel Disease (IBD) by Restoring Intestinal Barrier Integrity.

The management of dysfunctional intestinal epithelium by promoting mucosal healing and modulating the gut microbiota represents a novel therapeutic strategy for inflammatory bowel disease (IBD). As a convenient and well-tolerated method of drug delivery, intrarectal administration may represent a viable alternative to oral administration for the treatment of IBD. Here, a biomimetic supramolecular assembly of hyaluronic acid (HA) and β-cyclodextrin (HA-β-CD) for the delivery of the C domain peptide of insulin-like growth factor-1 (IGF-1C), which gradually releases IGF-1C, is developed.
