Torque Teno Virus (TTV)-A Potential Marker of Immunocompetence in Solid Organ Recipients.

Torque Teno Virus (TTV), first discovered in 1997, is a non-pathogenic, highly prevalent virus with a notable presence in the human virome. TTV has garnered attention as a potential indicator of immunocompetence in recipients of solid organ transplants. In this review, we discuss the role of TTV as a potential marker for immunosuppression optimization, prediction of graft rejection, and as an indicator of opportunistic infections.

Complementary Feeding Methods, Feeding Problems, Food Neophobia, and Picky Eating among Polish Children.

Proper nutrition during the first period of life is primarily related to meeting energy needs and providing essential nutrients that ensure the infant's normal physical and psychomotor development. Improper nutrition during this period, inadequate amounts of nutrients, inappropriate timing and manner of introduction of individual foods, can permanently alter metabolism and the course of physiological processes, increasing the risk of diseases such as obesity, allergic diseases, and cardiovascular diseases. This study aimed to verify how the method of complementary feeding influences the occurrence of food neophobia between 2 and 7 years of age, as well as to assess the different nutritional aspects resulting from the process of starting feeding other than breast milk and milk formula.

Initial work using open-chest access with a monopolar ablation device has been completed. This study describes the early development work for a device that can be used with subxiphoid access and deliver bipolar ablation pulses.

The characteristic of acute coronary syndromes of patients with multivessel coronary artery disease in centers with and without cardiac surgery on-site.

Background: Multivessel disease (MVD) is diagnosed in a fair number of patients with acute coronary syndrome (ACS). There are 36 cardiac-surgery (CS) centres and 157 catheterization laboratories dedicated to treat ACS in Poland. The aim of the study was to analyze MVD patient outcomes presented with ACS in centers with or without CS on-site.

Comparison of outcomes in patients with severe aortic stenosis treated with small and large Medtronic Evolut R and Evolut PRO self-expandable prosthetic valves.

Introduction: Indications for transcatheter aortic valve implantation (TAVI) continue to expand. Very often TAVI must be done in large annuli. Implantation of the bigger prostheses is often associated with more procedural problems, which may affect the outcomes.

Sex differences in the nutritional status and its association with long-term prognosis in patients with heart failure with reduced ejection fraction: a prospective cohort study.

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.

Echocardiographic predictors of positive left ventricular remodeling in patients with a history of active myocarditis.

Introduction: Myocarditis may be difficult to diagnose because of the variety of its clinical manifestations, and the clinical course of the disease can be unpredictable. Nevertheless, some patients may exhibit partial or full contractile recovery following myocarditis. Standard and speckle-tracking echocardiography may serve as tools to follow this recovery.

Does atrial fibrillation still increase the risk of death? One-year follow-up results of the NOMED-AF study.

Introduction: Although atrial fibrillation (AF) is a well‑known risk factor for ischemic stroke and hospitalization, its effect on mortality has not been clearly established.

Objectives: We aimed to assess whether AF is an independent risk factor for death. A secondary objective was to evaluate the role of oral anticoagulation in the prevention of stroke and death in 1‑year follow‑up of patients included in the NOMED‑AF (Noninvasive Monitoring for Early Detection of Atrial Fibrillation) study.

Anticoagulants versus Left Atrial Appendage Occlusion in Patients with Atrial Fibrillation and Co-Morbid Thrombocytopenia.

Left atrial appendage closure (LAAC) is an alternative approach to anticoagulants. Nonetheless, data regarding the outcomes of LAAC procedures in patients with thrombocytopenia remain lacking. The primary objective was to determine the incidence of the composite endpoint comprising ischemic stroke, intracranial hemorrhage, major bleeding, and cardiac cause of death among patients with atrial fibrillation (AF) and thrombocytopenia who were either undergoing LAAC or receiving oral anticoagulants.

The Influence of Hybrid Comprehensive Telerehabilitation on Anxiety in Heart Failure Patients: The TELEREH-HF Randomized Clinical Trial.

Telerehabilitation for heart failure (HF) patients is beneficial for physical functioning, prognosis, and psychological status. The study aimed at evaluating the influence of hybrid comprehensive telerehabilitation (HCTR) on the level of anxiety in comparison to usual care (UC). The TELEREH-HF study was a multicenter prospective RCT in 850 clinically stable HF participants.

Anomalous Origin of Left Circumflex Artery from the Right Sinus of Valsalva in Cardiac Computed Tomography in a Group of 16,680 Patients-Radiologic and Clinical Characteristics.

Background: Anomalous aortic origin of a coronary artery (AAOCA) is the most prevalent form of coronary anomaly. One variant of AAOCA is the anomalous origin of the left circumflex artery from the right sinus of Valsalva, which can be detected using cardiac computed tomography (CT). However, limited data are available regarding the natural history of this anomaly, its impact on myocardial function, and associated symptoms.

Cangrelor - Expanding therapeutic options in patients with acute coronary syndrome.

Cangrelor is the only intravenous P2Y12 receptor antagonist. It is an adenosine triphosphate analog that selectively, directly, and reversibly binds to the platelet P2Y12 receptors exerting its antiaggregatory effect. Cangrelor is characterized by linear, dose-dependent pharmacokinetics and rapid onset of action providing potent platelet inhibition exceeding 90%.

Predictors of ventricular tachyarrhythmia in patients with implantable cardioverter-defibrillator and non-ischemic systolic heart failure.

Background: The benefit derived from implantable cardioverter-defibrillators (ICD) in subjects with non-ischemic systolic HF (NICM) is less well-established.

Aim: The study aimed to determine the incidence, predictors, and prognostic impact of ventricular arrhythmias in patients with ICD and NICM.

Methods: The study sample included 377 consecutive patients with ICD or cardiac resynchronization cardioverter-defibrillators (CRT-D, 74% of patients) and NICM implanted and monitored remotely in a university hospital.

Stabilization of Graphene Oxide Dispersion in Plasma-like Isotonic Solution Containing Aggregating Concentrations of Bivalent Cations.

Unlabelled: Graphene oxide's (GO) intravascular applications and biocompatibility are not fully explored yet, although it has been proposed as an anticancer drug transporter, antibacterial factor or component of wearable devices. Bivalent cations and the number of particles' atom layers, as well as their structural oxygen content and pH of the dispersion, all affect the GO size, shape, dispersibility and biological effects. Bovine serum albumin (BSA), an important blood plasma protein, is expected to improve GO dispersion stability in physiological concentrations of the precipitating calcium and magnesium cations to enable effective and safe tissue perfusion.

Predictive factors of left ventricular ejection fraction improvement after myocardial infarction treated invasively.

Introduction: One indication for the implantation of a cardioverter-defibrillator is a reduction in the left ventricular ejection fraction (LVEF) ≤ 35%. However, in certain patients following an acute myocardial infarction (AMI) a gradual improvement in LVEF has been observed. The factors determining this increase in LVEF have not been conclusively determined.
