Coronary artery calcification as an incremental predictive risk: Research perspectives in primary prevention.

Coronary artery calcium (CAC) score is a neglected biomarker that can be derived from non-cardiac chest computed tomography scan and represents a surrogate for atherosclerosis. We created a simulation model using different CAC score values in the MESA coronary artery risk score in a population derived from the Fourier Trial. CAC score could modulate the sample sizes of cardiovascular trials in primary and secondary prevention and offer new primary prevention treatments to high-risk subjects with reasonable numbers needed to treat comparable to secondary prevention trials.

Sugar Cane ( L.) Waste Synthesized Si,N,S-Carbon Quantum Dots as High-Performance Corrosion Inhibitors for Mild Steel in Hydrochloric Acid.

This work reports the obtention of Si,N,S-CQDs from sugar cane bagasse and their inhibitory action on the mild steel corrosion in 1 mol L HCl solution. The CQDs were successfully obtained and characterized by X-ray photoelectron spectroscopy, Fourier-transform infrared spectroscopy, Dynamic light scattering, Raman, and UV-vis techniques, also showing endogenous self-doping. The anti-corrosive activity of CQDs was investigated by gravimetric tests, potentiodynamic polarization curves, electrochemical impedance measurements, atomic force microscopy, and scanning electron microscopy.

[Mineralocorticoid receptor antagonists in heart failure with preserved/mildly reduced ejection fraction: from TOPCAT to FINEARTS-HF].

Mineralocorticoid receptor antagonists (MRAs) represent one of the cornerstones of treatment for heart failure with reduced ejection fraction. Post-hoc data from the TOPCAT trial, conducted in patients with heart failure mildly reduced or preserved ejection fraction (HFmrEF/HFpEF), suggest the possible clinical benefit of MRAs, particularly for slightly reduced ejection fraction values. The advent of non-steroidal MRAs, including finerenone, seems to represent a turning point in the treatment for HFmrEF/HFpEF.

Impact of surgical strategy and postrepair transverse aortic arch size on late hypertension after coarctation repair during infancy.

Background: Late hypertension (HTN) after coarctation of the aorta (CoA) repair contributes to higher morbidity and mortality. An association between transverse aortic arch (TAA) hypoplasia and HTN has been found, but its relationship with surgical strategy is unclear. We studied the association between late HTN and initial surgical strategy pertaining to the TAA.

Prognostic role of gait speed in worsening heart failure.

Background: Worsening Heart Failure (WHF) is associated with adverse prognosis. Identifying novel prognostic markers in WHF is crucial. Gait speed (GS), a validated frailty index, is an easily obtainable parameter that may aid in reclassifying the risk of HF patients.

Low-cost heat assisted ambient ionization source for mass spectrometry in food and pharmaceutical screening.

Ambient Ionization Mass Spectrometry (AI-MS) techniques have revolutionized analytical chemistry by enabling rapid analysis of samples under atmospheric conditions with minimal to no preparation. In this study, the optimization of a cold atmospheric plasma for the analysis of food and pharmaceutical samples, liquid and solid, using a Heat-Assisted Dielectric Barrier Discharge Ionization (HA-DBDI) source is described. A significant enhancement in analyte signals was observed when a heating element was introduced into the design, potentially allowing for greater sensitivity.

Long-term outcomes of phenoclusters in preclinical heart failure with preserved and mildly reduced ejection fraction.

We applied phenomapping to the DAVID-Berg population, comprising subjects with preclinical HF, aiming to refine HF risk stratification.

Methods: The DAVID-Berg study prospectively enrolled 596 asymptomatic outpatients with EF > 40% with hypertension, diabetes mellitus or known cardiovascular disease.

Randomized Controlled Trial of Enhanced Recovery After Surgery Protocols in Live Kidney Donors: ERASKT Study.

Background: Enhanced recovery after surgery (ERAS) pathways represent a comprehensive approach to optimizing perioperative management and reducing hospital stay and cost. In living donor kidney transplantation, key impediments to postoperative discharge include pain, and opioid associated complications such as nausea, vomiting, and the return of gastrointestinal function.

Methods: In this randomized controlled trial, living kidney transplantation donors were assigned to either the ERAS or control group.

Moderate aortic stenosis in the dysfunctional ventricle: should it be treated?

Moderate aortic stenosis is associated with a worse prognosis than milder degrees. Pathophysiologically, this condition in a dysfunctional ventricle could lead to a further mechanism of haemodynamic worsening, so its treatment should lead to clinical advantages for the patient. The low risk of complications associated with percutaneous correction of aortic valve disease (transcatheter aortic valve implantation) should also be considered, which would seem to favour an interventional approach even in the aforementioned condition.

The Therapy and Management of Heart Failure with Preserved Ejection Fraction: New Insights on Treatment.

Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome characterised by the presence of diastolic dysfunction and elevated left ventricular filling pressure, in the setting of a left ventricular ejection fraction of at least 50%. Despite the epidemiological prevalence of HFpEF, a prompt diagnosis is challenging and many uncertainties exist. HFpEF is characterised by different phenotypes driven by various cardiac and non-cardiac comorbidities.

Tissue Engineering for Penile Reconstruction.

The penis is a complex organ with a development cycle from the fetal stage to puberty. In addition, it may suffer from either congenital or acquired anomalies. Penile surgical reconstruction has been the center of interest for many researchers but is still challenging due to the complexity of its anatomy and functionality.

Investigation on the source of VOCs emission from indoor construction materials using electronic sensors and TD-GC-MS.

Indoor air quality (IAQ) is critical to the health and wellbeing of people. As the majority of people spend greater amounts of time indoors, either in office spaces or households, the level of air pollutants in such environments is critical. Building materials and furniture are known sources of air pollutants such as Volatile Organic Compounds (VOCs) and may be associated with discomfort, detrimental health of the occupants, etc.

Clonal hematopoiesis of indeterminate potential: implications for the cardiologists.

Myeloproliferative neoplasms, including polycythemia vera, essential thrombocythemia, and myelofibrosis, are characterized by somatic gene mutations in bone marrow stem cells, which trigger an inflammatory response influencing the development of associated cardiovascular complications. In recent years, the same mutations were found in individuals with cardiovascular diseases even in the absence of hematological alterations. These genetic events allow the identification of a new entity called 'clonal hematopoiesis of indeterminate potential' (CHIP), as it was uncertain whether it could evolve toward hematological malignancies.

Socio-demographic influence on the pregnant women's comprehension of maternal health information in Tanzania.

Background: Pregnant women's understanding of maternal health information is critical in the application of information for pregnancy care, birth preparedness, and newborn care. However, the influence of socio-demographic characteristics on pregnant women's understanding of maternal health information is least understood.

Purpose: The study examined the influence of social and demographic characteristics on pregnant women's comprehension of maternal health information.

Heart Failure Preserved Ejection Fraction in Women: Insights Learned from Imaging.

While the prevalence of heart failure, in general, is similar in men and women, women experience a higher rate of HFpEF compared to HFrEF. Cardiovascular risk factors, parity, estrogen levels, cardiac physiology, and altered response to the immune system may be at the root of this difference. Studies have found that in response to increasing age and hypertension, women experience more concentric left ventricle remodeling, more ventricular and arterial stiffness, and less ventricular dilation compared to men, which predisposes women to developing more diastolic dysfunction.

Practical patient care appraisals with use of new potassium binders in heart failure and chronic kidney diseases.

Hyperkalaemia is a life-threatening condition leading to significant morbidity and mortality. It is common in heart failure and in chronic kidney disease (CKD) patients due to the diseases themselves, which often coexist, the high co-presence of diabetes, the fluctuations in renal function, and the use of some drugs [i.e.

Impact of diabetes on long-term outcomes of bifurcation percutaneous coronary intervention. An analysis from the BIFURCAT registry.

Background: It is still unclear the impact of diabetes mellitus (DM) in complex coronary lesions treated with percutaneous coronary intervention (PCI) which themselves are at increased incidence of adverse events.

Methods: BIFURCAT registry encompassed patients treated with PCI for coronary bifurcation lesion from the COBIS III and the RAIN registry. The primary endpoint was the occurrence of major cardiovascular adverse event (MACE), a composite and mutual exclusive of all-cause death or myocardial infarction (MI) or target-lesion revascularization (TLR).

Right ventricular contraction patterns in healthy children using three-dimensional echocardiography.

Background: The right ventricle (RV) has complex geometry and function, with motion along three separate axes-longitudinal, radial, and anteroposterior. Quantitative assessment of RV function by two-dimension echocardiography (2DE) has been limited as a consequence of this complexity, whereas newer three dimensional (3D) analysis offers the potential for more comprehensive assessment of the contributors to RV function. The aims of this study were to quantify the longitudinal, radial and anteroposterior components of global RV function using 3D echocardiography in a cohort of healthy children and to examine maturational changes in these parameters.

Metabolic profiling stratifies colorectal cancer and reveals adenosylhomocysteinase as a therapeutic target.

The genomic landscape of colorectal cancer (CRC) is shaped by inactivating mutations in tumour suppressors such as APC, and oncogenic mutations such as mutant KRAS. Here we used genetically engineered mouse models, and multimodal mass spectrometry-based metabolomics to study the impact of common genetic drivers of CRC on the metabolic landscape of the intestine. We show that untargeted metabolic profiling can be applied to stratify intestinal tissues according to underlying genetic alterations, and use mass spectrometry imaging to identify tumour, stromal and normal adjacent tissues.

Extracellular Matrix-Based and Electrospun Scaffolding Systems for Vaginal Reconstruction.

Congenital vaginal anomalies and pelvic organ prolapse affect different age groups of women and both have significant negative impacts on patients' psychological well-being and quality of life. While surgical and non-surgical treatments are available for vaginal defects, their efficacy is limited, and they often result in long-term complications. Therefore, alternative treatment options are urgently needed.
