Beyond the null: Recognizing and reporting true negative findings.

Science is based on ideas that might be true or false in describing reality. In order to discern between these two, scientists conduct studies that can reveal evidence for an idea, i.e.

Prognostic Impact of Insulin-Treated and Non-Insulin-Treated Diabetes in Patients with a Reduced Ejection Fraction After ST-Elevation Myocardial Infarction.

Background: Insulin- and non-insulin treated diabetes (ITDM and NITDM) have different prognostic impact in patients with myocardial infarction and/or heart failure. The aim of this study was to analyze the prognostic impact of ITDM and NTIDM on the incidence of all-cause mortality and major adverse cardiovascular events (MACE- cardiovascular death, nonfatal infarction, nonfatal stroke, and target vessel revascularization) in the 8-year follow-up of patients with ST-segment elevation myocardial infarction (STEMI) with a reduced ejection fraction (EF).

Methods: We analyzed 2230 consecutive STEMI patients treated with primary percutaneous coronary intervention and with EF < 50%.

Patient Preferences in Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) Screening and ICD Implantation: Canadian ARVC Registry Substudy.

Background: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is typically diagnosed following an arrhythmic event or during screening after a family member experiences sudden cardiac death. Implantation of a defibrillator (ICD) improves survival but can be associated with morbidity and risks, an important consideration within a shared decision-making context. This study examined patient decisional needs and preferences surrounding ARVC screening and prophylactic ICD implantation.

Pharmaco-Invasive Strategy Vs Primary Percutaneous Coronary Intervention for ST-Segment Elevation Myocardial Infarction in Latin America: A Meta-Analysis.

Background: Primary percutaneous coronary intervention (PCI) is the established treatment for ST-segment elevation myocardial infarction (STEMI), but often it is not readily available in low-resource settings. We assessed the safety and efficacy of the pharmaco-invasive strategy compared to primary PCI for STEMI in Latin America.

Methods: MEDLINE, Embase, and Latin American and Caribbean Health Sciences Literature (LILACS) were searched for the period from their inception to September 2023, for studies that compared a pharmaco-invasive strategy vs primary PCI in Latin America.

Background: Out-of-hospital cardiac arrest (OHCA) remains a prominent medical concern worldwide. Epidemiologic metrics and trends over time for OHCA cases in Canada are not well defined. This study evaluated geographic differences in the incidence and outcomes of OHCA patients admitted to hospitals across Canada, during the period 2013-2017.

The Canadian Heart Failure (CAN-HF) Registry: A Canadian Multicentre, Retrospective Study of Outpatients with Heart Failure.

Background: Guideline-directed medical therapy (GDMT) reduces events in patients with heart failure (HF) with reduced ejection fraction (HFrEF). Despite this impact, underutilization of GDMT persists. This report sought to describe HF management in Canadian outpatients treated at specialized HF clinics (HFCs).

Determining causal pathogens and inflammatory state of mastitis in dairy cows via Gram staining of precipitates in milk.

Early detection of bovine mastitis-causing pathogens is necessary for treatment. As culturing methods are time-consuming, a more rapid detection technique is required. This study investigated the sensitivity, specificity, and detection limit of Gram staining of milk precipitates (milk Gram stain, MGS) to detect bovine mastitis-causing pathogens in milk, as well as the potential of MGS to diagnose inflammation by counting polymorphonuclear leukocytes (PMN).

The Crucial Role of Bedside Echocardiography and Clinical Suspicion in Diagnosing Pulmonary Embolism With ST Elevation on ECG, Initially Misdiagnosed as ST-Segment Elevation Myocardial Infarction (STEMI).

Pulmonary embolism (PE) is a life-threatening condition with varied presentations, occasionally mimicking ST-segment elevation myocardial infarction (STEMI). This case highlights a 52-year-old male patient with a history of venous thromboembolism (VTE) who presented with progressive shortness of breath over a month, culminating in dyspnea at rest, and anterior ST-segment elevation on electrocardiography (ECG). The initial evaluation suggested STEMI.

Therapeutic exploration potential of adenosine receptor antagonists through pharmacophore ligand-based modelling and pharmacokinetics studies against Parkinson disease.

Unlabelled: Parkinson's Disease (PD) is a neurodegenerative disorder that primarily affects persons aged 65 and older. It leads to a decline in motor function as a result of the buildup of abnormal protein deposits called Lewy bodies in the brain. Existing therapies exhibit restricted effectiveness and undesirable side effects.

Examining spatiotemporal dynamics of CO emission at multiscale based on nighttime light data.

Carbon emissions have increasingly been the focus of all governments as countries throughout the world choose carbon neutrality as a national development strategy. The analysis of the spatiotemporal dynamics of CO emission has emerged as a significant research topic considering the dual-carbon goal. In this research, we explore the spatiotemporal changes of CO emission at different scales based on nighttime light data.

Long-term outcomes in five patients with autoimmune pulmonary alveolar proteinosis treated with molgramostim inhalation solution.

Autoimmune pulmonary alveolar proteinosis (aPAP), which accounts for >90% of all cases of PAP, is a rare lung disease mediated by granulocyte-macrophage colony-stimulating factor (GM-CSF) autoantibodies that block GM-CSF signalling, leading to reduced surfactant clearance causing abnormal accumulation of alveolar surfactant and impaired gas exchange [1-3]. The current standard of care for aPAP is whole-lung lavage (WLL), which is invasive, resource intensive, carries procedural risk, does not address the underlying cause of disease and often must be repeated regularly [4]. Hence, there is a therapeutical need to address the underlying pathophysiology of the disease.

Geochemical signatures and nanomechanical properties of echinoid tests from nearshore habitats of Florida: environmental and physiological controls on echinoid biomineralization.

The mechanisms that regulate minor and trace element biomineralization in the echinoid skeleton can be primarily controlled biologically (, by the organism and its vital effects) or by extrinsic environmental factors. Assessing the relative role of those controls is essential for understanding echinoid biomineralization, taphonomy, diagenesis, and their potential as geochemical archives. In this study, we (1) contrast geochemical signatures of specimens collected across multiple taxa and environmental settings to assess the effects of environmental and physiological factors on skeletal biomineralogy; and (2) analyze the nanomechanical properties of the echinoid skeleton to assess potential linkages between magnesium/calcium (Mg/Ca) ratios and skeletal nanohardness.

Machine learning Hubbard parameters with equivariant neural networks.

Density-functional theory with extended Hubbard functionals (DFT +  + ) provides a robust framework to accurately describe complex materials containing transition-metal or rare-earth elements. It does so by mitigating self-interaction errors inherent to semi-local functionals which are particularly pronounced in systems with partially-filled d and f electronic states. However, achieving accuracy in this approach hinges upon the accurate determination of the on-site and inter-site Hubbard parameters.

A Preliminary Evaluation of the Feasibility and Efficacy of Mantra-Like Phrase Recitation in Improving Mental Health in Autistic Adults.

Objectives: Mantra recitation has been shown to improve emotional well-being in neurotypical individuals with mental health conditions; however, no research has explored its effect on the autistic population. The private, routine nature of mantra and mantra-like recitation may offer unique advantages for autistic individuals struggling with negative emotions and emotion regulation. The purpose of this study was therefore to conduct a preliminary study of the feasibility and efficacy of a self-guided, online program of reciting secular mantra-like phrases in improving negative emotions and cognitive coping mechanisms.
