Motivated by the recently reported signatures of superconductivity in trilayer La_{4}Ni_{3}O_{10} under pressure, we comprehensively study this system using ab initio and random-phase approximation techniques. Without electronic interactions, the Ni d_{3z^{2}-r^{2}} orbitals show a bonding-antibonding and nonbonding splitting behavior via the O p_{z} orbitals inducing a "trimer" lattice in La_{4}Ni_{3}O_{10}, analogous to the dimers of La_{3}Ni_{2}O_{7}. The Fermi surface consists of three electron sheets with mixed e_{g} orbitals, and a hole and an electron pocket made up of the d_{3z^{2}-r^{2}} orbital, suggesting a Ni two-orbital minimum model.

Article Synopsis
  • - This study aims to determine how cardiac structure and function relate to mean left atrial pressure (LAP) in patients with atrial fibrillation (AF), as estimating left ventricular filling pressures can be difficult in these cases.
  • - Researchers included 101 patients undergoing transcatheter ablation, measuring invasive LAP during the procedure and echocardiography beforehand; they found that those with increased LAP had lower global longitudinal strain and poorer right ventricular function.
  • - Key predictors for elevated LAP included higher E/e' ratio and lower peak atrial longitudinal strain, with the minimum left atrial volume index being the best indicator; these findings offer insight into assessing cardiac filling pressures in AF patients.

  • This study investigates the effectiveness of HFPEF and HFA-PEFF scores in diagnosing heart failure with preserved ejection fraction (HFpEF) in patients with atrial fibrillation (AF), with a focus on their association with invasive left atrial pressure (LAP).
  • Researchers found that while higher scores indicated worse cardiac function, they did not show a significant link to elevated mean LAP.
  • Adding the measurement of left atrial indexed minimal volume (LAVi min) to these scores improved their accuracy in detecting elevated filling pressure in the studied patients.

Article Synopsis
  • - The study aimed to assess how the presence of raphe (a type of anatomical feature) in patients with bicuspid aortic valve (BAV) correlates with valve dysfunction, aortopathy, and the likelihood of needing aortic valve surgery.
  • - Researchers analyzed 695 BAV patients, finding that those with raphe experienced more moderate to severe aortic stenosis and a higher prevalence of aortopathy, particularly Type B, compared to those without raphe.
  • - The results indicated that having raphe significantly raises the odds of requiring aortic valve surgery within three years, highlighting the importance of monitoring patients with this anatomical feature.

Motivated by the recently discovered high-T superconductor LaNiO, we comprehensively study this system using density functional theory and random phase approximation calculations. At low pressures, the Amam phase is stable, containing the Y mode distortion from the Fmmm phase, while the Fmmm phase is unstable. Because of small differences in enthalpy and a considerable Y mode amplitude, the two phases may coexist in the range between 10.

Background: Clinical evaluation of central venous pressure is difficult, depends on experience, and is often inaccurate in patients with chronic advanced heart failure. We assessed the ultrasound-assessed internal jugular vein (JV) distensibility by ultrasound as a noninvasive tool to identify patients with normal right atrial pressure (RAP ≤7 mm Hg) in this population.

Methods: We measured JV distensibility as the Valsalva-to-rest ratio of the vein diameter in a calibration cohort (N=100) and a validation cohort (N=101) of consecutive patients with chronic heart failure with reduced ejection fraction who underwent pulmonary artery catheterization for advanced heart failure therapies workup.

  • The Italian Society of Echography and Cardiovascular Imaging (SIECVI) conducted a national survey to investigate stress echocardiography (SE) practices across Italy, collecting data from 228 laboratories in November 2022.
  • The survey revealed that out of 179 centers performing SE, most were located in northern Italy, and the study categorized them into low, moderate, and high volume of activity based on the number of SE examinations.
  • Key findings indicated differences in the use of stressors, with a tendency for high-volume centers to employ multiple stress techniques and incorporate advanced evaluations like coronary flow velocity reserve (CFVR) more frequently than low and moderate volume centers.

In cancer, a patient is considered a survivor from the time of initial diagnosis until the end of life. With improvements in early diagnosis and treatment, the number of cancer survivors (CS) has grown considerably and includes: (1) Patients cured and free from cancer who may be at risk of late-onset cancer therapy-related cardiovascular toxicity (CTR-CVT); (2) Patients with long-term control of not-curable cancers in whom CTR-CVT may need to be addressed. This paper highlights the importance of the cancer care continuum, of a patient-centered approach and of a prevention-oriented policy.

Aortic root dilatation has been proposed as hypertension-mediated organ damage (HMOD). Nevertheless, the role of the aortic root dilatation as a possible additional HMOD is still unclear since studies conducted so far are quite heterogeneous regarding the type of population analyzed, the aortic tract considered, and the type of outcomes accounted for. The aim of the present study is to assess whether the presence of aortic dilatation is associated with strong cardiovascular (CV) events (MACE: heart failure, CV death, stroke, acute coronary syndrome, myocardial revascularization) in a population of patients affected by essential hypertension.

  • - Severe aortic stenosis (AS) is the most prevalent type of valvular heart disease in seniors, affecting over 4% of individuals aged 75 and older, while cardiac amyloidosis, particularly "wild-type transthyretin" (wTTR), affects 22-25% of those over 80.
  • - Diagnosing both conditions together is difficult due to their similar effects on the left ventricle, which can complicate the identification of wTTR-CA in patients with AS.
  • - The review emphasizes the importance of multimodal imaging techniques, such as echocardiography and cardiac MRI, to help detect wTTR-CA early in individuals diagnosed with AS.

Cardiac tumors may be primary (either benign or malignant) or secondary (malignant) and are first detected by echocardiography in most cases. The cardiologist often challenges their identification, the differential diagnosis and the best therapeutic approach. Malignant tumors have usually a poor prognosis, which may be significantly improved by appropriate and timely therapies.

Sentiment quantification is the task of training, by means of supervised learning, estimators of the relative frequency (also called "prevalence") of sentiment-related classes (such as Positive, Neutral, Negative) in a sample of unlabelled texts. This task is especially important when these texts are tweets, since the final goal of most sentiment classification efforts carried out on Twitter data is actually quantification (and not the classification of individual tweets). It is well-known that solving quantification by means of "classify and count" (i.

The interaction between the implanter team and the imager team is critical to the success of transcatheter native mitral valve replacement (TMVR), a novel interventional procedure in the therapeutic arsenal for mitral regurgitation. This imaging scenario necessitates the addition of a new dedicated professional figure, dubbed "the interventional imager," with specific expertise in structural heart disease procedures. As its clinical application grows, knowledge of the various imaging modalities used in the TMVR procedure is required for the interventional imager and beneficial for the interventional implanter team.
