Early safety after TAVR according to VARC-3 criteria: incidence, predictors, and clinical impact.

Introduction And Objectives: The Valve Academic Research Consortium (VARC)-3 definition of the early safety (ES) composite endpoint after transcatheter aortic valve replacement (TAVR) lacks clinical validation. The aim of this study was to determine the incidence, predictors, and clinical impact of ES after TAVR as defined by VARC-3 criteria.

Methods: We performed a multicenter study including 10 078 patients with severe aortic stenosis undergoing transarterial TAVR.

New evidence for baroreflex and respiratory chemoreflex mediated cerebral sympathetic activation in humans.

The brain is highly innervated by sympathetic nerve fibres; however, their physiological purpose is poorly understood. We hypothesized that unilateral cerebral norepinephrine (NE) spillover, an index of cerebral sympathetic nerve activity (SNA), would be elevated when engaging the baroreflex [via lower-body negative pressure (LBNP; -20 and -40 Torr)] and respiratory chemoreflexes [via carbon dioxide (CO) administration (+8 Torr)], independently, and in combination. Twelve young and healthy participants (5 females) underwent simultaneous blood sampling from the right radial artery and internal jugular vein.

Impact of Implementing a Grossing Tumor-margin Distance Threshold for Frozen Section in Oncologic Lung Surgery.

Intraoperative frozen section (FS) examination of oncologic surgical specimens is frequently performed to ensure complete surgical resection. Data on the gross evaluation of surgical margins are limited. We recently published a study suggesting the use of a macroscopic 2.

Is the time right for preventive cardiology guidelines on sedentary behaviors and sitting time?

This review looks into sedentary behavior (SB) beyond its simplistic definition of "sitting" while also including sedentary activities. It explores the definition, physiological characteristics, prevalence, and guidelines of SB, contrasting it with physical activity (PA). The discussion encompasses: 1) the association between SB and mortality, with a specific focus on cardiovascular (CV) outcomes; 2) biological mechanisms linking SB to CV health, differentiating between the impacts of acute and chronic sitting additionally, 3) sex and gender differences in SB and, 4) SB as an independent CV risk factor are explored.

Association of genetically predicted levels of circulating blood lipids with coronary artery disease incidence.

Background And Aims: Estimating the genetic risk of coronary artery disease (CAD) is now possible by aggregating data from genome-wide association studies (GWAS) into polygenic risk scores (PRS). Combining multiple PRS for specific circulating blood lipids could improve risk prediction. Here, we sought to evaluate the performance of PRS derived from CAD and blood lipids GWAS to predict the incidence of CAD.

Moderate Aortic Stenosis With Cardiac Damage: A New Type of Severe Aortic Stenosis.

The clinical implications of severe aortic stenosis have been well established. Understanding of moderate aortic stenosis, however, continues to evolve. Athough moderate aortic stenosis may be less clinically impactful in patients with normal ventricular function, it may carry prognostic significance in those patients with a ventricle exhibiting signs of cardiac damage.

Impact of intensive versus nonintensive antithrombotic treatment on device-related thrombus after left atrial appendage closure.

Introduction And Objectives: The optimal antithrombotic therapy (AT) after left atrial appendage closure (LAAC) is debated. We assessed the impact of intensive vs nonintensive AT on the incidence of device-related thrombus (DRT) based on whether the device implantation was classified as optimal or suboptimal.

Methods: This study included patients who underwent successful LAAC in 9 centers.

N-Phenyl ureidobenzenesulfonates, a novel class of human dihydroorotate dehydrogenase inhibitors inducing differentiation and apoptosis in acute myeloid leukemia cells.

N-Phenyl ureidobenzensulfonates (PUB-SOs) are a novel family of dihydroorotate dehydrogenase (DHODH) inhibitors. Herein, we investigate the potential of PUB-SOs to induce acute myeloid leukemia (AML) cell differentiation and apoptosis. To that end, we screened our chemolibrary to select the most potent PUB-SOs based on their antiproliferative activity and their ability to arrest the cell progression of AML cells in the S phase.

Food choices, microstructure of ingestive behavior and sensory perceptions after bariatric surgery in women: A cross-sectional study.

Unlabelled: Results regarding the impact of bariatric surgery (BS) on food choices are inconsistent between studies based on self-reported questionnaires, and those using direct measurements. Moreover, the determinants of the modifications of food choices after BS, if any, are still poorly understood. This study compared food choices, food liking, microstructure of ingestive behavior and sensory perceptions between women who had BS in the last 18 months (BS group, n = 19; Roux-en-Y gastric bypass or sleeve gastrectomy) and women with BMI ≥35 kg m (OB group, n = 17) in ecological conditions and explored the associations of food choices with sensory perceptions and food liking.

Complex Thrombo-Inflammatory Responses versus Outcomes of Non-COVID-19 Community-Acquired Pneumonia and COVID-19.

Introduction: The thrombo-inflammatory response and outcomes of community-acquired pneumonia (CAP) due to various organisms (non-COVID-19 CAP) versus CAP due to a single virus, SARS-CoV-2 (i.e., COVID-19) may differ.

Consequences of adolescent sport-related concussion: exploring long-term cardiorespiratory fitness and adiposity.

Background: Little is known regarding long-term consequences (≥5 years) of sport-related concussion (SRC) sustained during adolescence. Adolescent SRC has been linked to athlete considerations of sport participation and subsequent retirement from sport during this critical developmental period. Prolonged SRC symptoms can reduce ability to perform physical activity, and research suggests inactivity can extend years post-injury.

Underreporting of adverse events to health authorities by healthcare professionals: a red flag-raising descriptive study.

Background: An adverse event (AE) is any undesirable medical manifestation in an individual who has received pharmacological treatment. To be considered serious (SAE), it needs to meet minimally one of the severity criteria by Health Canada. The most recent data (2006) suggested that AEs were underreported (<6%) to health authorities.

A scoping review of magnetic resonance angiography and perfusion image synthesis.

Introduction: Deregulation of the cerebrovascular system has been linked to neurodegeneration, part of a putative causal pathway into etiologies such as Alzheimer's disease (AD). In medical imaging, time-of-flight magnetic resonance angiography (TOF-MRA) and perfusion MRI are the most common modalities used to study this system. However, due to lack of resources, many large-scale studies of AD are not acquiring these images; this creates a conundrum, as the lack of evidence limits our knowledge of the interaction between the cerebrovascular system and AD.

State-of-the-Art Review of Aortic Root Reconstruction: Contemporary Techniques and Challenges.

Aortic root reconstruction operations have undergone substantial evolution with technical modifications, expanding indications, and the need for increasingly complex decision-making. The purpose of this state-of-the-art review is to detail our approach to contemporary aortic root reconstruction operations. First, we review the evolution of root reconstruction procedures over the years and discuss the approach to the aortic root patient for lifetime management of aneurysm and valvular disease in the modern context of management options.

Community versus academic hospital community-acquired pneumonia patients: a nested cohort study.

Background: Most Canadians receive their care in community hospitals, yet most clinical research is conducted in academic hospitals. This study aims to compare patients with community acquired pneumonia (CAP) treated in academic and community hospitals with respect to their demographics, clinical characteristics, treatments and outcomes.

Methods: This nested observational cohort substudy of the Community Acquired Pneumonia: Toward InnoVAtive Treatment (CAPTIVATE) trial included 1,329 hospitalized adults with CAP recruited between March 1st, 2018 and September 31st, 2023 from 15 Canadian hospitals.

Differentiating Separate Primary Lung Adenocarcinomas From Intrapulmonary Metastases With Emphasis on Pathological and Molecular Considerations: Recommendations From the International Association for the Study of Lung Cancer Pathology Committee.

Introduction: With the implementation of low-dose computed tomography screening, multiple pulmonary tumor nodules are diagnosed with increasing frequency and the selection of surgical treatments versus systemic therapies has become challenging on a daily basis in clinical practice. In the presence of multiple carcinomas, especially adenocarcinomas, pathologically determined to be of pulmonary origin, the distinction between separate primary lung carcinomas (SPLCs) and intrapulmonary metastases (IPMs) is important for staging, management, and prognostication.

Methods: We systemically reviewed various means that aid in the differentiation between SPLCs and IPMs explored by histopathologic evaluation and molecular profiling, the latter includes DNA microsatellite analysis, array comparative genomic hybridization, TP53 and oncogenic driver mutation testing and, more recently, with promising effectiveness, next-generation sequencing comprising small- or large-scale multi-gene panels.

Medication Exposure and Mortality in Patients With Schizophrenia.

Importance: The use of antipsychotics, antidepressants, and benzodiazepines may influence the risk of mortality in people with schizophrenia. However, many observational studies have not accounted for immortal time bias (ITB), which occurs when there is a period during which patients in the exposed group are necessarily alive and misclassified as exposed (the period between start of follow-up and initiation of drug). Ignoring ITB may lead to misinterpretation of the association between these drugs and mortality.

Oxidized Phospholipids and Calcific Aortic Valvular Disease.

Background: Oxidized phospholipids (OxPLs) are carried by apolipoprotein B-100-containing lipoproteins (OxPL-apoB) including lipoprotein(a) (Lp[a]). Both OxPL-apoB and Lp(a) have been associated with calcific aortic valve disease (CAVD).

Objectives: This study aimed to evaluate the associations between OxPL-apoB, Lp(a) and the prevalence, incidence, and progression of CAVD.

Piloting a Hospital Pharmacy Performance Model in the Face of Province-Wide Implementation of Activity-Based Funding in Quebec Health Care Centres.

Background: In the face of province-wide implementation of activity-based hospital funding in Quebec, a need arose to effectively measure pharmacists' contributions along the patient care trajectory and to enable pharmacy benchmarking using valid performance indicators.

Objectives: A 3-phase project was initiated to measure the performance and impact of pharmacists and pharmacy departments. Phases 2 and 3, described here, focused on gradually implementing, in various health care centres, the priority indicators selected in phase 1.

Molecular Features of Calcific Aortic Stenosis in Female and Male Patients.

Over the past 15 years, sex-related differences in aortic valve (AV) stenosis (AS) have been highlighted, affecting various aspects of AS, such as the pathophysiology, AV lesions, left ventricle remodelling, and outcomes. Female patients were found to present a more profibrotic pattern of leaflet remodelling and/or thickening, whereas male patients have a preponderance of calcification within stenosed leaflets. The understanding of these sex differences is still limited, owing to the underrepresentation of female patients in many basic and clinical research studies and trials.
