Background: Depression is common in patients with heart failure. The prevalence of depression is known to differ in male and female patients with heart failure, but little is known about whether these patients differ in predictors of depression. The purposes of this study were to: (1) determine whether the prevalence of depression in patients with heart failure differed by gender: (2) examine if predictors of depression differed by patient gender.

Methods: In this cross-sectional observational study, 147 patients with a primary diagnosis of heart failure completed five self-report questionnaires: demographic and clinical characteristic questionnaire, Mishel Uncertainty in Illness Scale, Beck Depression Inventory-II, Social Support Scale and Minnesota Living with Heart Failure Questionnaire. Data were analyzed with logistic regression.

Results: The majority of subjects were male (54.4%), with a mean age of 71.04 ± 13.29 years and mean ejection fraction of 46.42 ± 17.02%. About two-thirds of male patients (65%) and of female patients (65.7%) had significant depressive symptoms (Beck Depression Inventory-II score ≥14). More female than male patients had moderate or severe depressive symptoms. Stratified analyses revealed that significant independent predictors of depressive symptoms among males were being unemployed (odds ratio=.09, 95% confidence intervals=.02- .54), lower ejection fraction (odds ratio=.96, 95% confidence intervals=.92-1.00), and worse quality of life (odds ratio=1.09, 95% confidence intervals=1.05-1.14); among females, predictors were uncertainty (odds ratio=1.09, 95% confidence intervals=1.04-1.32) and worse quality of life (odds ratio=1.17, 95% confidence intervals=1.08-1.48).

Conclusions: Different variables predicted the presence of significant depressive symptoms in male and female patients with heart failure, but quality of life was an important factor in predicting depression in both genders.

Objectives: Cardiac biomarkers are useful for the diagnostic and prognostic assessment of myocardial injury (MI) and heart failure. By measuring specific proteins released into the bloodstream during heart stress or damage, these biomarkers help clinicians detect the presence and extent of heart injury and tailor appropriate treatment plans. This study aims to provide robust biological variation (BV) data for cardiac biomarkers in athletes, specifically focusing on those applied to detect or exclude MI, such as myoglobin, creatine kinase-myocardial band (CK-MB) and cardiac troponins (cTn), and those related to heart failure and cardiac dysfunction, brain natriuretic peptide (BNP) and N-terminal brain natriuretic pro-peptide (NT-proBNP).

The determinants of varicella-zoster virus (VZV)-associated central nervous system (CNS) infection have not been fully elucidated. This study aimed to investigate the incidence and risk factors, including immunosuppression, for different manifestations of VZV-associated CNS infection. Patient registers were used to include adults diagnosed with VZV-associated CNS infections between 2010 and 2019 in Sweden.

Extracorporeal Membrane Oxygenation (ECMO) is a modality of extracorporeal life support which allows temporary support in cases of cardiopulmonary failure and cardiogenic shock. This study presents a valveless pump that works by the Liebau effect as a possible pumping system in ECMO circuits, replacing the current roller and centrifugal pumps. For this purpose, a mock circulatory loop emulating the haemodynamic of the right part of the heart has been constructed.

Programmed necrosis/necroptosis greatly contributes to the pathogenesis of cardiac disorders including myocardial infarction, ischemia/reperfusion (I/R) injury and heart failure. However, the fundamental mechanism underlying myocardial necroptosis, especially the mitochondria-dependent death pathway, is poorly understood. Synaptotagmin-1 (Syt1), a Ca sensor, is originally identified in nervous system and mediates synchronous neurotransmitter release.
