Abstract A central line of inquiry into the sources generalized trust concerns how particularized (trust in known others) extends to (default expectations about trustworthiness people general). While we know that there is considerable cross-national variability strength relationship between and trust, little contextual factors shape degree which spills over more diffuse forms trust. We argue collectivism plays a key role extension The nature social interactions low societies conducive...

Importance Acute kidney injury (AKI) complicates 20% to 25% of hospital admissions and is associated with long-term mortality, especially from cardiovascular disease. Lower systolic blood pressure (SBP) following AKI may be lower but potentially at the cost higher short-term complications. Objective To determine associations SBP mortality readmissions AKI, whether time discharge affects these associations. Design, Setting, Participants This retrospective cohort study adults during a...

Automatic audio-visual urban traffic understanding is a growing area of research with many potential applications value to industry, academia, and the public sector. Yet, lack well-curated resources for training evaluating models in this hinders their development. To address we present curated dataset, Urban Sound & Sight (Urbansas), developed investigating detection localization sounding vehicles wild. Urbansas consists 12 hours unlabeled data along 3 manually annotated data, including...

Background: Machine-learning (ML) models, such as neural networks (NNs), have been proposed to predict antimicrobial susceptibility at the patient level while incorporating patient-level information from electronic medical record (EMR) systems. However, NNs often do not perform well in predicting rare outcomes, carbapenem resistance. We aimed apply a novel multitask NN create personalized antibiograms for individual patients with Escherichia coli clinical isolates resistance (AMR) four major...

Abstract Objective: Post-procedural antimicrobial prophylaxis is not recommended by professional guidelines but commonly prescribed. We sought to reduce use of post-procedural antimicrobials after common endoscopic urologic procedures. Design: A before-after, quasi-experimental trial with a baseline (July 2020–June 2022), an implementation and intervention period (August 2022–July 2023). Setting: Three participating medical centers. Intervention: assessed the effect bundled on excess ( ie ,...

Novel ST398 methicillin susceptible Staphylococcus aureus (MSSA) in the United States was first observed New York City (2004-2007); its diffusion across country resulted changing treatment options. Utilizing outpatient antimicrobial susceptibility data from Veterans Health Administration 2010 to 2019, spatiotemporal prevalence of potential MSSA is documented.

Sociological and urban studies have consistently reported that human behavior exhibits a discernible correlation with population size, following power-law function. Individuals residing in larger communities exhibit significantly higher levels of activity contrast to their counterparts smaller communities. However, the underlying processes responsible for such behavioral patterns remain unclear. The authors propose organizational crowding tends generate competitive pressure results social...

Abstract Using data from the Veterans’ Health Administration 2010 to 2019, we examined distribution and prevalence of community-acquired phenotypic extended-spectrum β-lactamase (ESBL) E. coli in United States. ESBL slowly increased during study period, cluster analysis showed clustering both urban rural locations.

2-deoxyglucose (2-DG), targeting Hexokinase I (HKI) to inhibit glycolysis in cancer cells, has inspired drug design. Increasing evidence suggests that its phosphorylated form, 2-deoxyglucose-6-phosphate (2-DG-6-P), may HKI more effectively, highlighting the need understand molecular mechanisms behind this effect. Using simulations, we examined interactions between and substrates—glucose (G) glucose-6-phosphate (G-6-P)—and inhibitors—2-DG 2-DG-6-P. G G-6-P showed stable with HKI, involving...
