Aims Many studies show the association between malnutrition and poor prognosis in heart failure (HF) patients. Our research aimed to analyse sex differences in patients with HF with reduced ejection fraction (HFrEF), emphasizing nutritional status and the influence of selected parameters on the prognosis. Methods and results We enrolled 276 consecutive patients diagnosed with HFrEF. Nutritional status was assessed using Mini Nutritional Assessment (MNA), geriatric nutritional risk index (GNRI), and body mass index (BMI). The mean follow-up period was 564.4 ± 346.3 days. The analysed group included 81.2% of men. The median age was 58, interquartile range (IQR) 49–64 years. Among all patients, almost 60% were classified as NYHA III or IV. Half of the participants were at risk of malnutrition, and 2.9% were malnourished. During follow-up, 72 (26.1%) patients died. The female sex was not associated with a higher occurrence of malnutrition (P = 0.99) or nutritional risk (P = 0.85), according to MNA. Coherently, GNRI scores did not differ significantly between the sexes (P = 0.29). In contrast, BMI was significantly higher in males (29.4 ± 5.3 vs. 25.9 ± 4.7; P < 0.001). Impaired nutritional status assessed with any method (MNA, GNRI, BMI) was not significantly associated with a worse prognosis. In multivariable analysis, NYHA class, lower estimated glomerular filtration rate, higher B-type natriuretic peptide (BNP), higher N-terminal fragment of proBNP, and higher uric acid were independent of sex and age predictors of all-cause mortality. Conclusion There were no sex differences in the nutritional status in the HFrEF patients, apart from lower BMI in females. Impaired nutritional status was not associated with mortality in both men and women. [ABSTRACT FROM AUTHOR]

From ancient times, when medicine was based on folk knowledge, to the present era of advanced science, the beneficial effects of plants on various diseases, including diabetes, have been discovered. Approximately 537 million people worldwide have diabetes, and forecasts indicate further increases. Hence, there is a need to develop new effective therapies and interventions to support diabetes treatment. Many plants impact carbohydrate metabolism, and the amount of in vitro and in vivo research on animals and humans continues to grow, updating our knowledge about their potential applications in diabetes treatment and its complications. This review discusses six plant sources with proven anti-diabetic activity. The study serves as a literature review on plants and their derived compounds that exhibit hypoglycemic effects, which are significant in managing prediabetic conditions and diagnosed diabetes.

Heart failure (HF) patients are vulnerable to a complicated course of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. This research analysed the relationship between the decision not to be immunised against SARS-CoV-2, clinical and epidemiological factors, and the pre-pandemic health-related quality of life (HRQoL) of HF patients. Before the onset of the SARS-CoV-2 pandemic, hospitalised HF patients were enrolled as a prospective cohort and interviewed using the World Health Organization's Quality of Life Brief Version questionnaire. On October 30, 2021, the immunisation status was verified. The association of vaccination hesitancy with epidemiological and clinical parameters and pre-pandemic questionnaire results was tested. Subsequently, independence from confounding factors such as age, sex, the New York Heart Association (NYHA) scale, and left ventricular ejection fraction (LVEF) was analyzed. Among the 136 included patients, 77.9% were vaccinated. Unvaccinated patients were younger (51.2 ± 13.2 vs 56.6 ± 10.3; p = 0.018) and more frequently had non-ischaemic aetiology of HF (73.3% vs 46.7%; p = 0.013). It was significant after adjustment for age, sex, NYHA class, and LVEF. There was no association of overall HRQoL or domain scores with vaccination status. Younger age as a factor associated with vaccine avoidance in this population is consistent with data from the general population despite higher exposure to the severe course of the disease.

Frailty syndrome (FS) has recently attracted attention as one of the major predictors of heart failure (HF) course severity. We aimed to develop a simple tool for predicting frailty in hospitalized HF patients using routine clinical parameters. A total of 153 hospitalized patients diagnosed with heart failure with reduced ejection fraction (HFrEF) were included in the study. Presence of FS was assessed with the SHARE-FI questionnaire. Clinical and biochemical parameters were collected. Using ROC curves and logistic regression analysis, a model predicting FS presence was developed and tested. Proposed model includes five variables with following cut-off values (1 point for each variable): age > 50 years, systolic pressure on admission < 110 mmHg, total cholesterol < 4.85 mmol/L, bilirubin ≥ 15.5 mmol/L, and alanine aminotransferase ≤ 34 U/L. Receiving 5 points was considered a high risk of FS with positive and negative predictive values (NPV), 83% and 72%, respectively, and specificity of 97%. Awarding 2 points or less ruled out FS in the studied group with negative predictive value 94%. The presented novel, simple score predicts FS in HFrEF patients with routine clinical parameters and has good positive and negative predictive values. [ABSTRACT FROM AUTHOR]

This study aimed to investigate the role of appetite loss and malnutrition in patients with heart failure with reduced ejection fraction (HFrEF). In this prospective, observational, single-center study, we enrolled 120 consecutive adults with HFrEF. We analyzed the selected clinical, echocardiographic, and biochemical parameters. Appetite loss and malnutrition were assessed by CNAQ (Council on Nutrition Appetite Questionnaire) and MNA (Mini Nutritional Assessment)/GNRI (Geriatric Nutritional Risk Index) questionnaires, respectively.Most patients were men (81.7%), mean age was 55.1 ± 11.3 years, and mean left ventricular ejection fraction was 23.9 ± 8.0%. The mean CNAQ score was 28.8 ± 3.9, mean MNA—23.1 ± 2.6, and mean GNRI—113.0 ± 12.3. Based on ROC curves, we showed that a sodium concentration <138 mmol/L had the greatest discriminating power for diagnosing impaired nutritional status (MNA ≤ 23.5) with a sensitivity of 54.5% and specificity of 77.8%. The threshold of HDL <0.97 mmol/L characterized 40.7% sensitivity and 86% specificity, B-type natriuretic peptide >738.6 pg/dL had 48.5% sensitivity and 80.8% specificity, high-sensitivity C-reactive protein >1.8 mg/L had 94.9% sensitivity and 42.9% specificity, and bilirubin >15 µmol/L had 78.2% sensitivity and 56.9% specificity. Nutritional status and appetite assessed by MNA/GNRI and CNAQ questionnaires showed poor correlations with other findings in HFrEF patients. [ABSTRACT FROM AUTHOR]

Diabetes mellitus is a significant health problem for medicine and economics. In 80-90% of cases, it is type 2 diabetes (T2DM). An essential aspect for people with T2DM is to control blood glucose levels and avoid significant deviations. Modifiable and non-modifiable factors influence the incidence of hyperglycemia and, sometimes, hypoglycemia. The lifestyle modifiable factors are body mass, smoking, physical activity, and diet. These affect the level of glycemia and impact molecular changes. Molecular changes affect the cell's primary function, and understanding them will improve our understanding of T2DM. These changes may become a therapeutic target for future therapy of type 2 diabetes, contributing to increasing the effectiveness of treatment. In addition, the influence of external factors (e.g., activity, diet) on each domain of molecular characterization has gained importance towards a better understanding of their role in prevention. In the current review, we aimed to collect scientific reports on the latest research about modifiable factors connected with the style of life which affect the glycemic level in the context of molecular discoveries.
