AI Article Synopsis
- The study explored the link between self-care practices and all-cause mortality in patients with chronic heart failure, involving 559 participants with an average age of 66.3 years.
- After analyzing data over a median follow-up period of 5.5 years, the researchers found that overall self-care did not significantly impact mortality rates, but low self-reported sodium intake was linked to increased risk of death.
- Other mortality predictors included being male, lack of a partner, more severe heart failure symptoms, and multiple health conditions, highlighting the need for further research on sodium intake and its long-term effects in chronic heart failure patients.
Article Abstract
Objectives: This study examined the association of self-care with all-cause mortality in a cohort of patients with chronic heart failure (HF).
Background: Although self-care is crucial to maintain health in patients with chronic HF, studies examining an association with clinical outcomes are scarce.
Methods: Consecutive patients with chronic HF (n = 559, mean age 66.3 ± 9.5 years, 78% men) completed the 9-item European Heart Failure Self-care Behaviour scale. Our endpoint was all-cause mortality. Associations between self-care and all-cause mortality were assessed with Kaplan-Meier analyses and multivariable Cox regression accounting for standard sociodemographic and clinical covariates, psychological distress, and self-rated health.
Results: After a median follow-up of 5.5 ± 2.4 years (range 16 weeks to 9.9 years), 221 deaths (40%) from any cause were recorded. There was no evidence of a mortality benefit in patients high over those low in global self-care (p = 0.71). In post hoc analyses, low self-reported sodium intake was associated with increased mortality (adjusted hazard ratio: 1.47; 95% confidence interval: 1.10 to 1.96; p = 0.01). Other significant predictors of mortality were: male sex, lack of a partner, New York Heart Association functional class III to IV, and increasing comorbid conditions.
Conclusions: Global self-care was not associated with long-term mortality whereas low self-reported sodium intake independently predicted increased all-cause mortality beyond parameters of disease severity. Replication of findings is needed as well as studies examining the correspondence of subjectively and objectively measured sodium intake and its effects on long-term prognosis in patients with chronic HF.

Purpose: Immune checkpoint inhibitors (ICIs) have demonstrated promise in the treatment of various cancers. Single-drug ICI therapy (immuno-oncology [IO] monotherapy) that targets PD-L1 is the standard of care in patients with advanced non-small cell lung cancer (NSCLC) with PD-L1 expression ≥50%. We sought to find out if a machine learning (ML) algorithm can perform better as a predictive biomarker than PD-L1 alone.

is one of the three most frequently mutated genes in age-related clonal hematopoiesis (CH), alongside and (. CH can progress to myeloid malignancies including chronic monomyelocytic leukemia (CMML) and is also strongly associated with inflammatory cardiovascular disease and all-cause mortality in humans. DNMT3A and TET2 regulate DNA methylation and demethylation pathways, respectively, and loss-of-function mutations in these genes reduce DNA methylation in heterochromatin, allowing derepression of silenced elements in heterochromatin.

Background And Aims: Cirrhosis is characterised by hyperdynamic circulation, which contributes to cirrhotic cardiomyopathy (CCM). However, the expert consensus on CCM did not initially include cardiac structure because of scant evidence. Therefore, this study investigated the associations of cardiac chamber geometry with mortality and CCM.

Introduction: Oral anticoagulants (OAC) reduce the risk of stroke among patients with atrial fibrillation (AF). However, adherence remains suboptimal. We focused on primary nonadherence to OAC and its associations with patient characteristics-specifically social determinants of health collected in electronic health records (EHR).
