Five-Year Comparison Results Between Clinically Severely Affected Tetralogy-of-Fallot Patients Initially Treated by Right Ventricular Outflow Stenting and Pink-Fallot Patients Undergoing Single-Step Correction.

The Purpose: Evaluation of the short-term and long-term results of a phased correction of the tetralogy of Fallot (ToF) with stenting of the right ventricular outflow tract (RVOT) in comparison with a one-stage total correction (TC) of the defect.

Materials And Methods: Two groups of patients with classical ToF were formed. Group 1 (n = 25; median age = 72 days) was initially represented by children with ToF with a more severe clinical status (median weight = 3.

Characteristics of Pulmonary Inflammation in Patients with Different Forms of Active Tuberculosis.

Targeted treatment of tuberculosis-associated lung damage requires an understanding of the precise mechanisms of immunopathology. A major obstacle to the longitudinal study of tuberculosis (TB) immunopathogenesis in humans is the lack of serial lung biopsies during disease progression and treatment, which could be used to characterize local immune pathways involved in tissue damage. Understanding of the immunobiology of lung tissue damage in tuberculosis has largely been based on animal models.

Randomized Clinical Trial of Hybrid vs. Surgical vs. Percutaneous Multivessel Coronary Revascularization: 5‑year Follow-up of HREVS Trial.

Aim      To evaluate 5-year results of the HREVS (Hybrid REvascularization Versus Standarts) study.Material and methods  The study included 155 consecutive patients with multivessel coronary artery disease who were randomized into 3 groups: coronary artery bypass grafting (CABG) (n=50), hybrid coronary revascularization (HCR) (n=52) and percutaneous coronary intervention (PCI) (n=53) according to the consensus of the cardiology team on the technical and clinical feasibility of each of the three coronary revascularization strategies. The primary endpoint of the study was residual ischemia 12 months after revascularization according to data of single-photon emission computed tomography (SPECT).

Lung Inflammation Signature in Post-COVID-19 TB Patients.

Tuberculosis (TB) remains a leading cause of infectious disease mortality worldwide, despite the COVID-19 pandemic. The mechanisms by which SARS-CoV-2 affects tuberculosis progression have not yet been established. Here, we compared the level of inflammation in the wall of the tuberculoma and in the parenchymal lung tissue of 30 patients diagnosed with tuberculoma without a history of COVID-19 and 30 patients diagnosed with tuberculoma 3 months after COVID-19.

High and Low Levels of Expression Are Associated with Two Distinct Gene Signatures in Lung Tissue of Pulmonary TB Patients with High Inflammation Activity.

P-glycoprotein (encoded by the gene) has a dual role in regulating inflammation and reducing chemotherapy efficacy in various diseases, but there are few studies focused on pulmonary TB patients. In this study, our objective was to identify a list of genes that correlate with high and low levels of gene expression in the lungs of pulmonary TB patients with different activity of chronic granulomatous inflammation. We compared gene expression in two groups of samples (with moderate and high activity of tuberculomas) to identify their characteristic gene signatures.
