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

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

Vocal Communication in Domestic Cats

This article describes the phonetic characteristics of the most common vocalisation types and subtypes in the domestic cat: the meow, the trill, the howl, the growl, the hiss (and the spit), the snarl (and the cry), the purr, the chirp and the chatter. In addition, the contexts where the different sounds are normally produced, and accompanying body postures and movements are summarised.

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

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

Exploring parent-child relationships in a Swedish child and adolescent psychiatry - cohort of adolescents with internet gaming disorder

Background: While recent studies suggest a high prevalence of Internet gaming disorder (IGD) in child and adolescent psychiatry (CAP) clinics, little is known about the factors contributing to problematic gaming among these patients. Given the well-established role of parenting and parent-child relationships in the development of problem behaviors, this study aimed to explore parent-child relation

Navigating the Challenges and Opportunities of Securing Internet of Autonomous Vehicles With Lightweight Authentication

The Internet of Things (IoT) can be defined as the network of physical objects, or "things,"embedded with sensors and software for processing and exchanging data with other devices and ecosystems using the Internet as a medium. With its rapid growth over the past decade, it has permeated several application domains, including intelligent vehicular systems. The Internet of Autonomous Vehicles (IoAV

Fostering industrial symbiosis in process industries : An innovation policy perspective

Industrial symbiosis (IS) holds significant potential to reduce resource consumption and improve economic efficiency within process industries. Previous studies have shown that innovative solutions play an important role in advancing IS. However, the role of policy instruments promoting innovation has not yet been systematically analysed in relation to industrial symbiosis. This study takes a deep

Toward a biological definition of neuronal and glial synucleinopathies

Cerebral accumulation of alpha-synuclein (αSyn) aggregates is the hallmark event in a group of neurodegenerative diseases—collectively called synucleinopathies—which include Parkinson’s disease, dementia with Lewy bodies and multiple system atrophy. Currently, these are diagnosed by their clinical symptoms and definitively confirmed postmortem by the presence of αSyn deposits in the brain. Here, w

External validation of a multivariable prediction model for positive resection margins in breast-conserving surgery

Objectives: Positive resection margins after breast-conserving surgery (BCS) most often demands a repeat surgery. To preoperatively identify patients at risk of positive margins, a multivariable model has been developed that predicts positive margins after BCS with a high accuracy. This study aimed to externally validate this prediction model to explore its generalizability and assess if additiona

Prognostic Testing for Prostate Cancer—A Cost-Effectiveness Analysis Comparing a Prostatype P-Score Biomarker Approach to Standard Clinical Practice

Background: The Prostatype score (P-score) is a prognostic biomarker that integrates a three-gene (IGFBP3, F3, and VGLL3) signature derived from prostate biopsy samples, with key clinical parameters, including prostate-specific antigen (PSA) levels, Gleason grade, and tumor stage at diagnosis. The test has demonstrated superior predictive accuracy for prostate cancer outcomes compared with traditi

Plasma-Derived von Willebrand Factor/Factor VIII Concentrate (Haemate P) in von Willebrand Disease : A Systematic Review and Pharmacovigilance Update

Background: Von Willebrand disease (VWD) is an inherited bleeding disorder caused by deficient or dysfunctional von Willebrand factor (VWF). VWF replacement therapy is indicated in VWD management. Methods: This systematic review was conducted to evaluate all available evidence of the efficacy, safety, dosing and consumption of pasteurized plasma-derived human coagulation FVIII/human VWF (pdVWF/FVI

Sowing the seeds of acoustic trapping : Towards rapid isolation of extracellular vesicles

Extracellular vesicles (EVs) carry biological information from their parent cell to other cells in the body. To intercept and decipher this information necessitates the isolation of EVs from complex backgrounds such as blood or spinal fluid. Acoustic trapping has been previously demonstrated as a promising technique for EV isolation from cell media, blood plasma and urine. The acoustic fields stru

Protection acquired upon intraperitoneal group a Streptococcus immunization is independent of concurrent adaptive immune responses but relies on macrophages and IFN-γ

Group A Streptococcus (GAS; Streptococcus pyogenes) is an important bacterial pathogen causing over 700 million superficial infections and around 500.000 deaths due to invasive disease or severe post-infection sequelae yearly. In spite of this major impact on society, there is currently no vaccine available against this bacterium. GAS strains can be separated into >250 distinct emm (M)-types, and
