[Features of the course and adverse events risk of coronavirus infection COVID-19 in hematological diseases (data from the CHRONOS19 register for the Primorsky Territory, intermediate stage)].

Aim: To assess the characteristics of the course of coronavirus infection COVID-19 and to determine the risk factors for adverse events in patients of the regional hematological center.

Materials And Methods: As part of an observational prospective cohort study, data from 144 medical records of patients in Primorsky Krai with hematological diseases and COVID-19 were analyzed. The data of the developed standardized questionnaire of the CHRONOS19 study were used.

Pediatric Osteoarticular Infections of the Hand and Wrist: A Retrospective Study.

Our understanding of pediatric osteoarticular infections (OAIs) has improved significantly in recent decades. is now recognized as the most common pathogen responsible for OAIs in pediatric populations younger than 4 years old. Research has provided a better understanding of the specific types, clinical characteristics, biological repercussions, and functional outcomes of these infections.

DYNAMICS OF THE MECHANICAL FUNCTION OF THE LEFT ATRIUM IN PATIENTS WITH ISCHEMIC MITRAL VALVE REGURGITATION.

Aim - to assess the left atrium (LA) mechanical function in patients with ischemic mitral regurgitation (IMR) using technologies of vector analysis of endocardium movement rate. The study enrolled 107 patients aged 56±7,5 among which 96 men (89,7%). The entry criteria: I-III degree of ischemic mitral regurgitation on echocardiography, angiography reveling coronary artery disease requiring surgical revascularization, sinus rhythm with the heart rate ranging from 60 to 89 per minute, superior echocardiography visualization of LA endocardium.

Evaluation ECMO in adult cardiac transplantation: can outcomes of marginal donor hearts be improved?

Aim: This study documents our experience with the use of ECMO in adult cardiac transplantation. Furthermore, in an attempt to improve outcomes of donor hearts with long ischemic times (LITs) we evaluated the efficacy of a strategy based on intraoperative ECMO (i-ECMO) circuit extended into postoperative cardiopulmonary support.

Methods: From February 2005 to September 2009, 11 patients (i-ECMO group) receiving allografts with LITs >7 hours underwent intraoperative ECMO circuit strategy with routine extension of ECMO into postoperative period.

A mortality risk assessment model for cardiac valve replacement surgery and its application in the use of prophylactic extracorporeal membrane oxygenation.

This study was conducted to establish a quantitative model to predict the risk of in-hospital mortality for patients undergoing cardiac valve replacement and to decrease mortality in patients with predicted high risk using prophylactic extracorporeal membrane oxygenation (PECMO). We retrospectively reviewed the medical records of 4482 patients who underwent cardiac valve replacement from January 1994 to December 2004, at Anzhen Hospital, Beijing, China. A total of 158 patients were going to receive heart valve replacement.

Video-assisted minimally invasive surgery for lone atrial fibrillation: a clinical report of 81 cases.

Objective: We sought to evaluate the feasibility and efficacy of a new type of video-assisted minimally invasive surgery for patients with atrial fibrillation.

Methods: Between December 2006 and February 2008, 81 patients with lone atrial fibrillation (49 with paroxysmal, 17 with persistent, and 15 with long-standing persistent atrial fibrillation) underwent this therapy with a bipolar radiofrequency ablation system. The main surgical procedures included bilateral pulmonary vein antrum isolation, obliteration of the left atrial appendage, division of the ligament of Marshall, and intraoperative electrophysiologic testing.

Shortening transplantation periods of potato plantlets by use of potassium humate and kadostim and their effects on mini-tuber production.

Plantlets produced from meristem culture of six advanced cultivars (Agria, Advanced clone 397007-9, Marfona, Sante, Satina and Ceaser) propagated by single node cuttings arranged in a RCBD base factorial design with ten replications. Factor A was plantlets produced from meristem culture of advanced cultivars and factor B was seven treatments (four concentrations of potassium humate as 0.5, 1, 1.

Determination of yield stability in advanced potato cultivars as affected by water deficit and potassium humate in Ardabil region, Iran.

This experiment was done on the three potato cultivars [Agria (susceptible), Satina (semi-tolerant) and Ceaser (tolerant to water deficit)] and three irrigation treatments (after 30 mm evaporation from basin class A, after 60 mm evaporation + spraying by Potassium Humate, and after 60 mm evaporation from basin class A) for two locations in 2007. Experimental design was Split Plot with three replications. Potassium Humate spraying (250 mL ha(-1)) were done in three stages of emergence, before tuberization and during tuberization period.

Tolerance of 42 bread wheat genotypes to drought stress after anthesis.

The present research characterized yield and yield components of 42 wheat genotypes after terminal drought stress. The experiment was in twice replicated simple rectangular lattice design, conducted at irrigated and terminal stress conditions during 2006-2007. These study genotypes had significant differences for grain yield at level of 1%.

The key role of apoptosis in the pathogenesis and treatment of pulmonary hypertension.

In recent years, the process of the programmed cell death has gained much interest because it has important pathophysiological consequences contributing to the deletion of unwanted cells in the vessel wall, loss of pulmonary smooth muscle cells and therefore in reversing the pulmonary pressure. For the reason that most patients with pulmonary hypertension present with limited reversibility with vasodilators, antiremodeling approach for treatment appears to be feasible. Induction or enhancement of vascular smooth muscle cells apoptosis may be targeted to develop novel therapeutic approaches for pulmonary vascular remodeling in patients with pulmonary hypertension.
