Biocompatibility of two model elastin-like recombinamer-based hydrogels formed through physical or chemical cross-linking for various applications in tissue engineering and regenerative medicine

Biocompatibility studies, especially innate immunity induction, in vitro and in vivo cytotoxicity, and fibrosis, are often lacking for many novel biomaterials including recombinant protein-based ones, such as elastin-like recombinamers (ELRs), and has not been extensively explored in the scientific literature, in contrast to traditional biomaterials. Herein, we present the results from a set of ex

Associations of intraoperative end-tidal CO2 levels with postoperative outcome-secondary analysis of a worldwide observational study

BACKGROUND: Patients receiving intraoperative ventilation during general anesthesia often have low end-tidal CO2 (etCO2). We examined the association of intraoperative etCO2 levels with the occurrence of postoperative pulmonary complications (PPCs) in a conveniently-sized international, prospective study named 'Local ASsessment of Ventilatory management during General Anesthesia for Surgery' (LAS

Mitoxantrone alters CD24/Siglec-10 expression in malignant brain tumor models

Medulloblastoma and glioblastoma are the most common malignant primary brain tumors in children and adults, respectively. Tumor-associated macrophages and microglia are key non-cancerous cell types in these tumors. These cells interact with CD24, a so called “don’t eat me signal” expressed on tumor cells, through Siglec-10, a receptor that contributes to immune evasion by promoting an immunosuppre

Personalizing bariatric metabolic surgery : Predictors of weight-loss success and risk of weight recurrence

Background Bariatric metabolic surgery (Roux-en-Y gastric bypass [RYGB] and sleeve gastrectomy [SG]) effectively treats obesity and type 2 diabetes; however, weight loss varies, necessitating predictive factors. Methods We analysed 12- and 24-month weight loss data from 811 patients (RYGB or SG). Factor Analysis of Mixed Data and neural network (NN) modelling identified distinct patient phenotypes

A novel multimodal imaging approach for working diagnosis of acute myocardial infarction with non-obstructive coronary arteries : a promising diagnostic strategy

Background: Myocardial infarction with non-obstructive coronary arteries (MINOCA) demands prompt mechanistic clarification. Early integration of coronary CT angiography (CCTA) and cardiovascular magnetic resonance (CMR) can refine diagnosis during the acute phase. Methods: Twenty-one consecutive patients (41 ± 10 years; 71% men) presenting with troponin-positive chest pain and unobstructed coronar

Global molecular landscape of early MASLD progression in human obesity

Metabolic dysfunction-associated steatotic liver disease (MASLD) is often asymptomatic early on but can progress to irreversible conditions like cirrhosis. Due to limited access to human liver biopsies, systematic and integrative molecular resources remain scarce. In this study, we performed transcriptomic analyses on liver and metabolomic analyses on liver and plasma samples from morbidly obese i

Cardiometabolic outcomes with dapagliflozin after myocardial infarction by baseline ejection fraction : DAPA-MI

Aims: In the randomized DAPA-MI clinical trial, 10 mg of dapagliflozin once daily improved cardiometabolic outcomes versus placebo after acute myocardial infarction (MI) in patients without established diabetes or heart failure (HF). We assessed associations between baseline left ventricular ejection fraction (LVEF) and cardiometabolic outcomes in DAPA-MI. Methods: The primary outcome, assessed us

A systemic overreaction to years versus decades of warming in a subarctic grassland ecosystem

Temperature governs most biotic processes, yet we know little about how warming affects whole ecosystems. Here we examined the responses of 128 components of a subarctic grassland to either 5–8 or >50 years of soil warming. Warming of >50 years drove the ecosystem to a new steady state possessing a distinct biotic composition and reduced species richness, biomass and soil organic matter. However,

Impact of neoadjuvant therapy on short-term outcomes after left pancreatectomy : A propensity score–matched international multicenter study

Background: Neoadjuvant therapy is protective of postoperative pancreatic fistula in pancreatoduodenectomy. However, the effect of neoadjuvant therapy after left pancreatectomy remains unclear. The aim of this international multicenter study was to evaluate the impact of neoadjuvant therapy on short term outcomes after left pancreatectomy for pancreatic ductal adenocarcinoma. Methods: Patients und

Quantitation of PET spatial extent as a potential adjunct to visual interpretation of [18F]flortaucipir imaging : TAU-SPEX

Purpose: Among visually Tau-PET-positive scans, large variation exists in the size of the visually tau-positive area. Here, we propose a metric quantifying the spatial extent of visual Tau-PET-positivity, termed “TAU-SPEX”, and evaluate associations with visual read status, neurofibrillary tangle (NFT) pathology at autopsy, and cognition. Methods: [18F]flortaucipir data from 1,645 participants (ag

Fractional Flow Reserve to Guide Revascularization in Patients With Coronary Artery Disease Undergoing TAVR

Background The prognostic value of fractional flow reserve (FFR) in assessing coronary stenosis before transcatheter aortic valve replacement (TAVR) is unclear. Objectives The aim of this study was to evaluate cardiovascular risks associated with significant and nonsignificant FFR values of coronary stenosis prior to TAVR. Methods Patients were enrolled from the NOTION-3 (Nordic Aortic Valve Inter

Classification of postoperative pancreatic fistula after left pancreatectomy : International multicentre cohort study

Background Postoperative pancreatic fistula (POPF) is a major complication after left pancreatectomy. The current International Study Group of Pancreatic Surgery classification has limitations, including heterogeneity in morbidity and high interobserver variability. This study aimed to assess POPF-related morbidity after left pancreatectomy and propose a refined classification system. Methods Pati

Non-local X-ray intermolecular radiative decay probes solvation shell of ions in water

Aqueous solutions are crucial in chemistry, biology, environmental science, and technology. The chemistry of solutes is influenced by the surrounding solvation shell of water molecules, which have different chemical properties than bulk water due to their different electronic and geometric structure. It is experimentally challenging to selectively investigate this property-determining electronic a

European Stroke Organisation (ESO) and European Association of Neurosurgical Societies (EANS) guideline on stroke due to spontaneous intracerebral haemorrhage

Spontaneous (non-traumatic) intracerebral haemorrhage (ICH) affects ~3.4 million people worldwide each year, causing ~2.8 million deaths. Many randomised controlled trials and high-quality observational studies have added to the evidence base for the management of people with ICH since the last European Stroke Organisation (ESO) guidelines for the management of spontaneous ICH were published in 20

Genome-Wide Association Study of Symptom Change Following Cognitive Behavioral Therapy for Common Mental Disorders

Cognitive behavioral therapy (CBT) is a well-established, evidence-based treatment for common mental disorders such as depression, anxiety disorders, and obsessive-compulsive disorder (OCD). However, treatment outcomes vary widely, and a substantial proportion of patients do not achieve sufficient improvement. Robust predictors of individual differences in symptom change are currently lacking. Gen

CD44v6 is associated with tumor aggressiveness and chemoresistance in bladder cancer

Bladder cancer is a fast-moving and recurrent malignancy where survival hinges on early detection and precise risk stratification. The search for robust biomarkers is urgent, and CD44v6 has emerged as a compelling candidate. In this study, we explored the clinical and functional associations of CD44v6 expression in bladder cancer. Integrated analyses of patient samples and cell lines showed that h

Proteogenomic Workflow Reveals Molecular Phenotypes Related to Breast Cancer Mammographic Appearance

Proteogenomic approaches have enabled the generat̲ion of novel information levels when compared to single omics studies although burdened by extensive experimental efforts.

Predictors of deterioration of lung function in cystic fibrosis.

The severity of lung disease in cystic fibrosis (CF) may be related to the type of mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, and to environmental and immunological factors. Since pulmonary disease is the main determinant of morbidity and mortality in CF, it is important to identify factors that can explain and predict this variation. The aim of this longitudi

LUCAS versus manual chest compression during ambulance transport : A hemodynamic study in a porcine model of cardiac arrest

Background—Mechanical chest compression (CC) is currently suggested to deliver sustained high-quality CC in a moving ambulance. This study compared the hemodynamic support provided by a mechanical piston device or manual CC during ambulance transport in a porcine model of cardiopulmonary resuscitation. Methods and Results—In a simulated urban ambulance transport, 16 pigs in cardiac arrest were ra

Increased vimentin in human α- and β-cells in type 2 diabetes

Type 2 diabetes (T2DM) is associated with pancreatic islet dysfunction. Loss of β-cell identity has been implicated via dedifferentiation or conversion to other pancreatic endocrine cell types. How these transitions contribute to the onset and progression of T2DM in vivo is unknown. The aims of this study were to determine the degree of epithelial-to-mesenchymal transition occurring in α and β cel
