Predictors of Lethality, Remodeling, and Aorta-Related Events in Different Types of Proximal Aortic Dissection Surgery.

Unlabelled: is to analyze predictors of lethality, false lumen thrombosis, enlargement of aortic diameter, and frequency of aorta-related events in the early and remote postoperative periods for various types of proximal aortic dissection surgery using the logistic regression method.

Materials And Methods: A retrospective observational comparison of the results of surgical treatment of 213 patients with the diagnosis of "DeBakey type I aortic dissection" has been carried out. The participants were divided into three groups: group 1 underwent classic aortic arch reconstruction using hemiarch technique or total reconstruction of the aortic arch with a multiple-branch prosthesis (n=121); group 2 was subjected to the hemiarch technique and implantation of bare-metal (uncoated) stents (n=55); in group 3, the "frozen elephant trunk" correction technique was used (n=37).

Frozen Elephant Trunk for Aortic Dissection Using Different Hybrid Grafts: Preliminary Results from a Prospective Study.

Background: The frozen elephant trunk technique has become popular and led to an expansion of indications for surgery. Various hybrid grafts for the frozen elephant trunk are used, sometimes with significantly different features. The objective of this study was to compare early- and mid-term outcomes after the frozen elephant trunk for aortic dissection using different hybrid grafts.

Is it possible to predict postoperative blood loss in surgery for idiopathic scoliosis?

Introduction: Postoperative drain loss can exceed intraoperative blood loss and affect the severity of the patient's condition. Aim: The objective of the study was to find significant predictors of postoperative blood loss in surgery for idiopathic scoliosis.

Materials And Methods: We analyzed the data of 140 patients with idiopathic scoliosis.

Hybrid Technologies for Reconstruction of Proximal Aortic Dissection.

Unlabelled: is to evaluate the efficacy of various types of hybrid technology in compare to the classical repair of the aortic arch of type I aortic dissection treatment in the in-hospital period.

Materials And Methods: A retrospective observational study has been conducted, the results of surgical treatment of 213 patients with DeBakey type I aortic dissection operated on within the period from 2001 to 2017 were compared. Patients were divided into three groups: in group 1, patients undergone a hemiarch type of aortic repair or the total arch replacement (n=121); in group 2, a hemiarch aortic reconstruction and implantation of bare metal stent was performed (n=55); in group 3, a frozen elephant trunk technique was used (n=37).

[Atrial fibrillation and cognitive impairment: features of the relationship, developmental and prevention mechanisms].

The article discusses the development of cognitive deficit in patients with atrial fibrillation (AF) and provides data on mechanisms of the development of cognitive disorders in AF. Under discussion are a possibility of reducing the risk of cognitive disorders with the anticoagulant therapy for prevention of stroke in AF and different properties of different anticoagulants, which may be important for patients. Thus, patients with cognitive disorders are more prone to missing the dose, which may entail serious, possibly fatal consequences.

[Predictors of early adverse events after the frozen elephant trunk procedure].

Aim: The aim of this study was to identify predictors of adverse events after the frozen elephant trunk procedure in the early postoperative period.

Patients And Methods: Between March 2012 and March 2020, a total of 273 patients were operated on for aortic pathology. A retrospective analysis aimed at identifying probable predictors was performed on 83 patients who underwent the FET procedure.

Comparative characteristics of a pacemaker implantation after biatrial or left atrial ablation of atrial fibrillation in combination with coronary artery bypass grafting in patients with ischemic heart disease and long-standing persistent atrial fibrillation.

Aim      To compare the incidence of a permanent pacemaker (PP) implantation based on the chosen treatment technology (biatrial ablation, BA, or left atrial ablation (LAA) for long-standing persistent atrial fibrillation (AF) with simultaneous coronary bypass (CB).Material and methods  The study included 116 patients with long-standing persistent AF and indications for CB. Patients were randomized to two equal groups (58 patients in each).

The Effect of Smith-Peterson Osteotomy on Blood Loss during Surgical Correction of Adolescent Idiopathic Scoliosis.

Introduction: Surgical correction of adolescent idiopathic scoliosis is inevitably accompanied by blood loss. About 37-85% of patients undergo allogeneic transfusions associated with a risk of serious complications. Prediction of the expected blood loss volume remains a topical problem.

[Long-Term Survival of Patients with Ischemic Heart Disease After Surgical Correction of Moderate Ischemic Mitral Regurgitation].

Aim: to assess effect of correction of moderate ischemic mitral regurgitation (IMR) in patients with ischemic cardiomyopathy (IMC) in immediate and remote period.

Materials And Methods: We included in a single center prospective study 76 patients with IMC, left ventricular ejection fraction ≤35 %, and moderate IMR. Patients with indications to postinfarction aneurism repair were not included.

Perspectives of using pulmonary arterial stiffness indicators to evaluate the prognosis of patients with pulmonary arterial hypertension.

Aim: The aim of the study was to characterize the mechanical properties of the pulmonary arterial wall (PA) in patients with pulmonary arterial hypertension (PAH) using magnetic resonance imaging (MRI) of the heart, and to determine their diagnostic and prognostic value.

Materials And Methods: 57 patients with PAH were examined. The diagnosis of PAH was verified according to the recommendations of the ERS/ESC from 2015.

Expression of TNFα Receptors on Immunocompetent Cells Is Increased in Atopic Dermatitis.

Background: Expression levels of cytokine and growth factor receptors have been found to be important in the regulation of their action. Tumor necrosis factor-α (TNFα) is actively involved in inflammation processes in atopic dermatitis (AD), but the role of TNFα membrane receptors (TNFR) and their regulatory function in AD remains unclear.

Aim: We aimed to determine the associations of parameters of TNFRα expression on immunocompetent cells with disease severity before and after therapy in AD patients.

Expression density of receptors to IL-1β in atopic dermatitis.

Interleukin 1 (IL-1 β) and the system for regulation of its biological effects play an important role in the development and behavior of inflammatory processes in atopic dermatitis. Notably, cells that are actively involved in the pathological process have altered expression of cytokine receptors. However, standard evaluation of cells by flow cytometry measures only the percentage of cells expressing the appropriate marker, which is not enough for a full assessment of these changes.
