Heart failure and mental health conditions frequently coexist and have a negative impact on health-related quality of life and prognosis. We aimed to evaluate depression and anxiety symptoms and to determine the association between psychological distress and cardiac parameters in heart failure with reduced and mildly reduced ejection fraction. A total of 43 patients (33 male, mean age 64 ± 10 years) with heart failure and left ventricular systolic dysfunction (29 with HFrEF, 14 with HFmrEF) underwent comprehensive echocardiographic evaluation. All study participants completed questionnaires for the assessment of depression (PHQ-9), anxiety (GAD-7), and health-related quality of life (MLHFQ). Ten (34%) patients with HFrEF and two (14%) participants with HFmrEF had moderate-to-severe depression symptoms. Significant anxiety symptoms were more frequent in HFrEF (10 vs. 2 patients; 34% vs. 14%). Poor quality of life was also more common among patients with HFrEF (17 vs. 5 patients; 59% vs. 36%), showing higher MLHFQ scores (p = 0.009). Moreover, PHQ-9, GAD-7, and MLHFQ scores showed significant correlations between NYHA class severity and the presence of peripheral edema. The symptoms of dyspnea correlated with both PHQ-9 and MLHFQ scores. Significant correlations were observed between MLHFQ scores and a large number of clinical features, such as exercise capacity, 6MWT distance, the need for furosemide, echocardiographic parameters (LVEDVI, LVESVI, LVEF, LVGLS, SVI), and laboratory variables (albumin, GFR, NT-proBNP). In the multiple linear regression analysis, dyspnea proved to be a significant predictor of higher PHQ-9 and MLHFQ scores, even after adjusting for potential confounders. High symptom burden due to psychological distress is common among patients with HFrEF and HFmrEF. More efficient control of congestion may improve depression, anxiety symptoms, and health-related quality of life.

Vitamin D emerged as an important prognostic biomarker in heart failure (HF), with currently highly debated therapeutic implications. Several trials on vitamin D supplementation in HF showed improvements in left ventricular (LV) remodeling and function and health-related quality of life (HRQoL), which did not translate into mid- to long-term beneficial effects regarding physical performance and mortality. We addressed total 25-hydroxyvitamin D (25(OH)D), serum albumin, and uric acid (UA) levels, focusing mainly on vitamin D deficiency, as potential markers of LV systolic dysfunction in HF with reduced and mildly reduced ejection fraction (HFrEF, HFmrEF). Seventy patients with LVEF < 50% were comprehensively evaluated using ECG, echocardiography, lung ultrasound (LUS), blood sampling, and the six-minute walk test (6MWT). HRQoL was also assessed using the Minnesota Living with Heart Failure Questionnaire (MLHFQ). Statistically significant positive correlations were found between LVEF, 25(OH)D, serum UA, and albumin, respectively (p = 0.008, p = 0.009, and p = 0.001). Serum UA (7.4 ± 2.4 vs. 5.7 ± 2.1, p = 0.005), NT-proBNP levels (1090.4 (675.2–2664.9) vs. 759.0 (260.3–1474.8), p = 0.034), and MLHFQ scores (21.0 (14.0–47.0) vs. 14.5 (4.5–25.5), p = 0.012) were significantly higher, whereas 25(OH)D concentrations (17.6 (15.1–28.2) vs. 22.7 (19.5–33.8), p = 0.010) were lower in subjects with severely reduced LVEF. Also, 25(OH)D was independently associated with LVEF in univariate and multiple regression analysis, maintaining its significance even after adjusting for confounders such as age, NT-proBNP, the presence of chronic coronary syndrome, hypertension, and anemia. According to our current findings, 25(OH)D is closely associated with LVEF, further supporting the need to establish correct vitamin D supplementation schemes and dietary interventions in HF. The changes in LVEF, 25(OH)D, serum UA, and albumin levels in HFrEF and HFmrEF indicate a similar pathophysiological background.

The COVID-19 lockdown has had serious consequences, including rethinking higher education. The study aims to enhance the knowledge base of online education and academic integrity through a case study of the Ludovika University of Public Service (LUPS), Budapest, Hungary. The research aimed to assess the teachers' experience with distance learning and examinations, including the change in workload, digital competencies, Moodle, Turnitin, and other software used during and after the lockdown. This paper summarizes the university-level policy changes induced during the lockdown, covering the introduction of emergency distance teaching and online examinations in academic integrity at the university. Two years after the first lockdown, the researchers made a survey (n = 145) about the continuation of the introduced solutions. The results show that a remarkable reordering started while the technical and technological backgrounds were available for the changes. The teachers could feel a significant increase in workload with distance education and have low trust in maintaining the standards of academic integrity. However, the research shows moderate and low levels of digital competencies in the majority of teachers, which clearly defines the most crucial task leading to success. Maintaining the monitoring system with objective indicators of the development and the opinions of the interested parties is essential for successful strategies in the field. [ABSTRACT FROM AUTHOR]
