Simultaneous Unbinned Differential Cross-Section Measurement of Twenty-Four Z+jets Kinematic Observables with the ATLAS Detector.

Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins.

Importance: Delirium is common after cardiac surgery and associated with adverse outcomes. Intraoperative benzodiazepines may increase postoperative delirium but restricting intraoperative benzodiazepines has not yet been evaluated in a randomized trial.

Objective: To determine whether an institutional policy of restricted intraoperative benzodiazepine administration reduced the incidence of postoperative delirium.

Is There a Need to Reassess Protein Intake Recommendations Following Metabolic Bariatric Surgery?

Purpose Of Review: Protein intake is recognized as a key nutritional factor crucial for optimizing Metabolic Bariatric Surgery (MBS) outcomes by preventing protein malnutrition, preserving fat-free mass, and inducing satiety. This paper discusses the current evidence regarding protein intake and its impact on clinical outcomes following MBS.

Recent Findings: There are considerable gaps in the understanding of protein requirements following MBS, as existing guidelines are based on limited and inconsistent reports.

Fatal overdoses among people with HIV experiencing nonfatal overdoses in British Columbia, Canada.

The breadth of the overdose crisis is underestimated because of a lack of quantifying nonfatal overdoses. We estimate the proportion of nonfatal overdoses among all people with HIV (PWH) in British Columbia, Canada, and the prevalence of fatal overdoses among people who had a nonfatal overdose, stratified by sex. A small proportion of PWH who experienced a nonfatal overdose subsequently died of a fatal overdose, signaling opportunities for crucial interventions and treatment to prevent overdose death.

Assessing Physician Motivation to Engage in Continuing Professional Development on Artificial Intelligence.

To realize the transformative potential of artificial intelligence (AI) in health care, physicians must learn how to use AI-based tools effectively, safely, and equitably. Continuing professional development (CPD) activities are one way to learn how to do this. The purpose of this article is to describe a theory-based approach for assessing health professionals' motivation to participate in CPD on AI-based tools.

Evidence that staphylococcal superantigens promote within-patient bacterial persistence following post-operative surgical site infection.

is a predominant cause of post-operative surgical site infections and persistent bacteremia. Here, we describe a patient who experienced three episodes of infection over a period of 4 months following a total knee arthroplasty. The initial bloodstream isolate (SAB-0429) was a clonal complex 5 (CC5) and methicillin-resistant (MRSA), whereas two subsequent isolates (SAB-0485 and SAB-0495) were CC5 isolates but methicillin-sensitive .

EZH2 inhibition enhances the activity of Carboplatin in aggressive-variant prostate cancer cell lines.

Background: Aggressive Variant Prostate Cancers (AVPCs) are incurable malignancies. Platinum-based chemotherapies are used for the palliative treatment of AVPC. The Polycomb Repressive Complex 2 (PRC2) promotes prostate cancer progression histone H3 Lysine 27 tri-methylation (H3K27me3).

Patient perceptions of persistent symptoms after mild traumatic brain injury and their influence on mental health treatment-seeking: a grounded theory study.

Purpose: Mental health conditions after mild traumatic brain injury (mTBI) are common and can complicate injury outcomes, but are under-treated. According to the Common Sense Model of Self-Regulation, the way patients perceive their health conditions can influence the way they manage them, including if, when, and how they seek treatment. This study explored how individuals perceive persistent symptoms after mTBI, in order to develop a grounded theory about what motivates and demotivates them to seek mental health treatment after their injury.

Minimally invasive compared to open surgery in patients with low-risk cervical cancer following simple hysterectomy: An exploratory analysis from the Gynegologic Cancer Intergroup/Canadian Cancer Trials Group CX.5/SHAPE trial.

Objective: The Laparoscopic Approach to Cervical Cancer trial demonstrated that minimally invasive radical hysterectomy was associated with worse disease-free survival and overall survival among women with early-stage cervical cancer. It is unknown whether this applies to patients with low-risk disease following simple hysterectomy.

Methods: Among patients who underwent simple hysterectomy in the Simple Hysterectomy And PElvic node assessment trial, univariate and multivariate Cox models were used to assess the association of minimally invasive versus open surgery with clinical outcomes, including pelvic and extra-pelvic recurrence-free survival, overall recurrence-free survival, and overall survival.

Surface immobilization of single atoms on heteroatom-doped carbon nanospheres through phenolic-mediated interfacial anchoring for highly efficient biocatalysis.

Single-atom catalysts (SACs) dispersed on support materials exhibit exceptional catalytic properties that can be fine-tuned through interactions between the single atoms and the support. However, selectively controlling the spatial location of single metal atoms while simultaneously harmonizing their coordination environment remains a significant challenge. Here, we present a phenolic-mediated interfacial anchoring (PIA) strategy to prepare SACs with Fe single atoms anchored on the surface of heteroatom-doped carbon nanospheres.

SPIRIT-DEFINE explanation and elaboration: recommendations for enhancing quality and impact of early phase dose-finding clinical trials protocols.

Unlabelled: Transparent and accurate reporting in early phase dose-finding (EPDF) clinical trials is crucial for informing subsequent larger trials. The SPIRIT statement, designed for trial protocol content, does not adequately cover the distinctive features of EPDF trials. Recent findings indicate that the protocol contents in past EPDF trials frequently lacked completeness and clarity.

CONSORT-DEFINE explanation and elaboration: recommendations for enhancing reporting quality and impact of early phase dose-finding clinical trials.

Unlabelled: Early phase dose-finding (EPDF) trials are key in the development of novel therapies, with their findings directly informing subsequent clinical development phases and providing valuable insights for reverse translation. Comprehensive and transparent reporting of these studies is critical for their accurate and critical interpretation, which may improve and expedite therapeutic development. However, quality of reporting of design characteristics and results from EPDF trials is often variable and incomplete.

The design space of E(3)-equivariant atom-centred interatomic potentials.

Molecular dynamics simulation is an important tool in computational materials science and chemistry, and in the past decade it has been revolutionized by machine learning. This rapid progress in machine learning interatomic potentials has produced a number of new architectures in just the past few years. Particularly notable among these are the atomic cluster expansion, which unified many of the earlier ideas around atom-density-based descriptors, and Neural Equivariant Interatomic Potentials (NequIP), a message-passing neural network with equivariant features that exhibited state-of-the-art accuracy at the time.

Impact of Policy Changes Expanding Access to Direct-Acting Antivirals on Hepatitis C Virus-Related Hospitalizations in People With HIV: A Population-Based Study.

Background: The burden of hepatitis C virus (HCV)-related hospitalizations is substantial, particularly among people with HIV and HCV. In Ontario, Canada, use of direct-acting antivirals (DAAs) increased following policies removing fibrosis-stage restrictions and approving of pangenotypic agents in 2017 and 2018, respectively. We examined the impact of expanded DAA access on HCV-related hospitalizations in people with HIV.

Background: Vaping during pregnancy remains under researched and under reported, making appropriate prevention, health promotion and intervention difficult to design and mount. In this article we assessed the experiences and considerations of women who vape during pregnancy and/or within 2 years post-partum, in order to underpin realistic and informative health information for women and providers in face of conflicting and minimal guidance.

Design: 22 interviews were conducted with pregnant and post-partum women who vape(d) nicotine, cannabis, or both during pregnancy and/or after delivery.

How dairy heifers initially respond to freestalls: The effect of neck-rail placement.

Dairy heifers are often kept on open packs early in life and later transitioned to freestalls. The neck rail in freestalls acts as a barrier intended to prevent animals from entering too far in the stall, with the aim of improving stall cleanliness. Unfortunately, this barrier can hinder stall use and may be a hazard to animals due to physical contact, perhaps especially when animals first learn to use the stall.

Stocking density at feeders and drinkers and temporal feed restriction affects dairy cows' drinking behavior.

Water is an essential resource for dairy cows, and its consumption is closely linked to feed intake. Social competition can lead to changes in drinking behavior, especially for subordinate cows. We studied how changes in stocking density at the feeder (1 or 2 cows per feeder), and drinker (6 or 12 cows per drinker) and a temporal feed restriction (14- or 24-h access) affects drinking in 4 groups of 6 cows each, following a Latin square design.
