Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection and it remains the most frequent cause of death amongst critically ill patients worldwide, despite recent medical advancements. The cardiac involvement in sepsis, better known as sepsis-induced cardiomyopathy, represents a form of cardiac dysfunction identified in septic patients, characterized by ventricular dilation, myocardial involvement, decreased ejection fraction and reversibility. Although the implications of cardiac involvement in sepsis can be extremely severe, this affliction has not been intensely debated in literature. Therefore, in order to better understand this affliction, we need to identify new markers. Two biomarkers, endothelin-1 (ET-1) and the soluble form of suppression of tumorigenicity 2 protein (sST2) have previously been linked to both sepsis and acute/chronic heart failure. Endothelin-1 is part of a family of amino acid peptides, that is mainly produced by endothelial cells and exerts a vasoconstrictive effect, but also causes fibrosis of the vascular cells, stimulates production of reactive oxygen species and induces proinflammatory mechanisms. During sepsis, it induces coronary vasoconstriction, decreased cardiac output, increased vascular resistance and permeability and increased fluid flux into the extravascular space on cardiac level, as well as affecting the contractility of myocardial myocytes. High values of serum ET-1 have also been identified in septic shock and in endotoxin-induced febrile responses in rats. The Suppression of tumorigenicity 2 protein (ST2) is a member of the interleukin-1 receptor family and is involved in T helper 2 cells-associated immune response. Recent studies identified a close link between ST2 and both inflammatory and heart diseases. Furthermore, it was recently approved by the Food and Drug Administration as a prognostic biomarker in heart failure and is recommended for the evaluation of additional cardiovascular risk.

Chronic kidney disease represents a complex and multifaceted pathology characterized by the presence of structural or functional renal anomalies associated with a persistent reduction in renal function. As the disease progresses, complications arise due to the chronic inflammatory syndrome, hydro-electrolytic disorders, and toxicity secondary to the uremic environment. Cardiovascular complications are the leading cause of death for these patients. Ischemic cardiac pathology can be both a consequence and complication of chronic kidney disease, highlighting the need to identify specific cardiorenal dysfunction biomarkers targeting pathophysiological mechanisms common to both conditions. This identification is crucial for establishing accurate diagnoses, prognoses, and risk stratifications for patients. This work is intended to elucidate the intricate relationship between chronic kidney disease and ischemic heart disease and to investigate the roles of cardiorenal biomarkers, including cardiac troponin, natriuretic peptides, galectin-3, copeptin, fibroblast growth factor 23 and its co-receptor Klotho, soluble suppression of tumorigenicity 2, and plasma growth differentiation factor 15.

Introduction: The overall risk of dental procedures should be rigorously assessed, including the cumulative risk of latex contamination (gloves, instruments, operating fields), local anesthesia, composite materials and in addition the patient's personal risk (cardiovascular). Material and methods: the study was retrospective and was performed in a rural community, respectively Pătrăuți locality, Suceava county. Data were collected on the factors that characterize the lifestyle and working conditions of the analyzed population, heredo - collateral and personal history, anthropometric data, biochemical parameters( lipid profile, glycemia and glycated hemoglobin, BP, presence of obesity and diabetes type 2, as well as data on dental allergic risk. Results: the prevalence of hypertensive patients among the general population was 14.79% ; Adult patients diagnosed with hypertension are 34.48% male (140 patients) and 65.52% female (266 patients), the prevalence of hypertension among the adult population being 8.09% for men and 18.38% for women. Conclusions: Hypertension was a common risk factor in the study population, which raised the additional risk profile in the dental office, especially among the Roma population, decreasing the addressability to the office.

1. Background: Literature data on bacterial infections and their impact on the mortality rates of COVID-19 patients from Romania are scarce, while worldwide reports are contrasting. 2. Materials and Methods: We conducted a unicentric retrospective observational study that included 280 patients with SARS-CoV-2 infection, on whom we performed various microbiological determinations. Based on the administration or not of the antibiotic treatment, we divided the patients into two groups. First, we sought to investigate the rates and predictors of bacterial infections, the causative microbial strains, and the prescribed antibiotic treatment. Secondly, the study aimed to identify the risk factors associated with in-hospital death and evaluate the biomarkers’ performance for predicting short-term mortality. 3. Results: Bacterial co-infections or secondary infections were confirmed in 23 (8.2%) patients. Acinetobacter baumannii was the pathogen responsible for most of the confirmed bacterial infections. Almost three quarters of the patients (72.8%) received empiric antibiotic therapy. Multivariate logistic regression has shown leukocytosis and intensive care unit admission as risk factors for bacterial infections and C-reactive protein, together with the length of hospital stay, as mortality predictors. The ROC curves revealed an acceptable performance for the erythrocyte sedimentation rate (AUC: 0.781), and C-reactive protein (AUC: 0.797), but a poor performance for fibrinogen (AUC: 0.664) in predicting fatal events. 4. Conclusions: This study highlighted the somewhat paradoxical association of a low rate of confirmed infections with a high rate of empiric antibiotic therapy. A thorough assessment of the risk factors for bacterial infections, in addition to the acknowledgment of various mortality predictors, is crucial for identifying high-risk patients, thus allowing a timely therapeutic intervention, with a direct impact on improving patients’ prognosis.

Background: Biomarkers, electrocardiogram (ECG) and Holter ECG are basic, accessible and feasible cardiac investigations. The combination of their results may lead to a more complex predictive model that may improve the clinical approach in acute heart failure (AHF). The main objective was to investigate which ECG parameters are correlated with the usual cardiac biomarkers (prohormone N-terminal proBNP, high-sensitive cardiac troponin I) in patients with acute heart failure, in a population from Romania. The relationship between certain ECG parameters and cardiac biomarkers may support future research on their combined prognostic value. Methods: In this prospective case-control study were included 49 patients with acute heart failure and 31 participants in the control group. For all patients we measured levels of prohormone N-terminal proBNP (NT-proBNP), high-sensitive cardiac troponin I (hs-cTnI) and MB isoenzyme of creatine phosphokinase (CK-MB) and evaluated the 12-lead ECG and 24 h Holter monitoring. Complete clinical and paraclinical evaluation was performed. Results: NT-proBNP level was significantly higher in patients with AHF (p < 0.001). In patients with AHF, NT-proBNP correlated with cQTi (p = 0.027), pathological Q wave (p = 0.029), complex premature ventricular contractions (PVCs) (p = 0.034) and ventricular tachycardia (p = 0.048). Hs-cTnI and CK-MB were correlated with ST-segment modification (p = 0.038; p = 0.018) and hs-cTnI alone with complex PVCs (p = 0.031). Conclusions: The statistical relationships found between cardiac biomarkers and ECG patterns support the added value of ECG in the diagnosis of AHF. We emphasize the importance of proper ECG analysis of more subtle parameters that can easily be missed. As a non-invasive technique, ECG can be used in the outpatient setting as a warning signal, announcing the acute decompensation of HF. In addition, the information provided by the ECG complements the biomarker results, supporting the diagnosis of AHF in cases of dyspnea of uncertain etiology. Further studies are needed to confirm long-term prognosis in a multi-marker approach.
