Clinical significance of a new diagnosis of atrial fibrillation in patients with vascular disease

Background: The Cardiovascular Outcomes for People Using Anticoagulation Strategies (COMPASS) trial enrolled patients with vascular disease but excluded patients requiring oral anticoagulation. Objective: We aimed to explore the clinical significance of a new diagnosis of atrial fibrillation (AF) during follow-up. Methods: New AF was identified from hospitalization, study drug discontinuation, and

The influence of three-gendered grammatical systems on simultaneous bilingual cognition : The case of Ukrainian-Russian bilinguals

This paper examines the linguistic relativity principle (Whorf, 1956) by investigating the impact of grammatical gender on cognition in simultaneous bilinguals of three-gendered Ukrainian and Russian. It examines whether speakers of three-gendered languages show grammatical gender effects on categorisation, empirically addressing claims that such effects are insignificant due to the presence of th

The Alzheimer's Association Global Biomarker Standardization Consortium (GBSC) plasma phospho-tau Round Robin study

INTRODUCTION: The Alzheimer's Association Global Biomarker Standardization Consortium conducted a blinded case–control study to learn which phosphorylated tau (p-tau) assays provide the largest fold-changes in Alzheimer's disease (AD) versus non-AD and show commutability in measuring patient samples and candidate certified reference materials (CRMs). METHODS: Thirty-three different p-tau assays me

A Review of International Approaches for Development of Climate Reference Periods – for Hygrothermal Analysis of Buildings

In recent years, Sweden has seen substantial changes to its building designs, especially regarding the envelope and ventilation systems, across both renovations and new constructions. Although enhancements like better insulation and new building materials have boosted energy efficiency, they have also led to moisture-related problems such as stains, mold, and decay. To address these issues, heat a

SELective defunctioning Stoma Approach in low anterior resection for rectal cancer (SELSA) : Protocol for a prospective study with a nested randomized clinical trial investigating stoma-free survival without major LARS following total mesorectal excision

Aim: Accumulated data suggest that routine use of defunctioning stoma in low anterior resection for rectal cancer may cause kidney injury, bowel dysfunction and a higher risk of permanent stomas. We aim to study whether avoidance of a diverting stoma in selected patients is safe and reduces adverse consequences. Methods: SELSA is a multicentre international prospective observational study nesting

Birthweight and risk of chronic kidney disease after a type 2 diabetes diagnosis in the DD2 cohort

Aims/hypothesis: Low birthweight (LBW) is associated with younger age, less obesity and more hypertension among people recently diagnosed with type 2 diabetes, as well as increased cardiovascular morbidity and mortality risk. It is not known whether LBW is associated with an increased risk of incident chronic kidney disease (CKD) among people with a type 2 diabetes diagnosis. Methods: Original mid

Confirmatory Biopsy Outcomes in Patients with Grade Group 2 Prostate Cancer : Implications for Early Management

Background and objective: Guideline recommendations regarding early management of grade group (GG) 2 prostate cancer with confirmatory biopsy (cBx) are not well established. Our aim was to determine which patients with GG 2 cancer should undergo cBx before treatment decision-making by evaluating the probability of downgrading to GG 1 or no cancer on cBx. Methods: This was a single-institution retr

Cardiac ATP production and contractility are favorably regulated by short-term S100A9 blockade after myocardial infarction

Introduction: The infarcted heart is energetically compromised exhibiting a deficient production of adenosine triphosphate (ATP) and the ensuing impaired contractile function. Short-term blockade of the protein S100A9 improves cardiac performance in mice after myocardial infarction (MI). The implications upon ATP production during this process are not known. Objectives: This study evaluates whethe

IgA vasculitis nephritis - outcomes in adult-onset disease

Objectives: IgA vasculitis (IgAV) in adults has been relatively under-investigated. Since outcomes are worse in other forms of vasculitis with increasing age, we investigated the outcomes of IgAV comparing younger adults (18-34), middle-aged adults (35-64) and elderly patients (≥64 years) focusing on kidney outcomes. Methods: We identified patients with renal biopsy-confirmed IgAV nephritis and co

Sleep-Administered ketamine/psychedelics : A streamlined strategy to address two challenges in research on ketamine and psychedelics

The dissociative effects of ketamine and psychedelics might be associated with their rapid antidepressant properties, raising questions about whether these effects are necessary for their therapeutic action. Additionally, the distinct dissociative experiences often reported by patients in clinical trials may reveal whether they receive an active treatment or a placebo, potentially introducing bias

Uncertainty-Aware Decision-Making and Planning for Autonomous Forced Merging

In this paper, we develop an uncertainty-aware decision-making and motion-planning method for an autonomous ego vehicle in forced merging scenarios, considering the motion uncertainty of surrounding vehicles. The method dynamically captures the uncertainty of surrounding vehicles by online estimation of their acceleration bounds, enabling a reactive but rapid understanding of the uncertainty chara

Robust motion planning for autonomous vehicles based on environment and uncertainty-aware reachability prediction

Planning and navigation in real-time traffic is challenging, since the driving environment (e.g., road network and infrastructure) is complex and the accurate prediction of surrounding vehicles is hard. To address this, this paper proposes an environment and uncertainty-aware robust motion-planning strategy. The method achieves environment awareness by considering road-geometry constraints in the

Robust Predictive Motion Planning by Learning Obstacle Uncertainty

Safe motion planning for robotic systems in dynamic environments is nontrivial in the presence of uncertain obstacles, where estimation of obstacle uncertainties is crucial in predicting future motions of dynamic obstacles. The worst case characterization gives a conservative uncertainty prediction and may result in infeasible motion planning for the ego robotic system. In this article, an efficie

Comparative Kinetics of Supported Lipid Bilayer Formation on Silica Coated Vertically Oriented Highly Curved Nanowires and Planar Silica Surfaces

Supported lipid bilayers (SLBs), formed via lipid vesicle adsorption on highly curved silica surfaces, are widely used in biosensor applications and as models for curved cell membranes. However, SLB formation is often hindered on convex structures with radii comparable to the vesicles. In this study, lightguiding semiconductor nanowires (NWs), engineered for fluorescence signal enhancement, were u

A Minimax Optimal Controller for Positive Systems

We present an explicit solution to the discrete-time Bellman equation for minimax optimal control of positive systems under unconstrained disturbances. The primary contribution of our result relies on deducing a bound for the disturbance penalty, which characterizes the existence of a finite solution to the problem class. Moreover, this constraint on the disturbance penalty reveals that, in scenar

Varieties of Economic Elites? : Preliminary Results From the World Elite Database (WED)

The strategies, decisions and beliefs of those who occupy prominent positions of economic power have influence on very large corporations and the markets they dominate, on vast amounts of economic resources, and on the rules of the game. However, the sociology of elites faces a dual challenge: divergent conceptualisations of what can be considered as a position of economic power and internationall

(Un)sheltered from the storm : A wind shelter as focal point for recreational nature use conflicts

In recent years, a growing interest in sustainable tourism and outdoor recreation has emerged in Sweden and globally. While a positive development for many reasons, it coincides with other shifting patterns in recreational nature use, influenced by climate change, social media, and experimental interventions in natural areas. These developments bring opportunities to broaden participation, but als

Sub-cycle nanotip field emission of electrons driven by air plasma generated THz pulses

Terahertz pulses generated by two-color laser plasmas have reported peak field strengths exceeding MV/cm, and when illuminating metal nanotips, the near-field enhancement at the tip apex should result in extremely high bunch charges and electron energies via sub-cycle cold-field emission. Here, electron emission from tungsten nanotips driven by THz pulses generated by a long filament air-plasma is
