Neutrophil extracellular traps characterize caseating granulomas.

Tuberculosis (TB) remains one of the top 10 causes of death worldwide and still poses a serious challenge to public health. Recent attention to neutrophils has uncovered unexplored areas demanding further investigation. Therefore, the aim of this study was to determine neutrophil activation and circulatory neutrophil extracellular trap (NET) formation in various types of TB.

Drug-Resistant Tuberculosis, Georgia, Kazakhstan, Kyrgyzstan, Moldova, and Ukraine, 2017-2022.

In 2021, the World Health Organization recommended new extensively drug-resistant (XDR) and pre-XDR tuberculosis (TB) definitions. In a recent cohort of TB patients in Eastern Europe, we show that XDR TB as currently defined is associated with exceptionally poor treatment outcomes, considerably worse than for the former definition (31% vs. 54% treatment success).

Treatment outcomes and risk factors for an unsuccessful outcome among patients with highly drug-resistant tuberculosis in Ukraine.

Objectives: To describe demographics, clinical features, and treatment outcomes of patients with highly drug-resistant tuberculosis (TB) in Ukraine, and to evaluate risk factors for an unsuccessful outcome.

Methods: Data from patients with multi-, pre-extensively, or extensively drug-resistant TB were collected prospectively from TB dispensaries in 15 out of 24 Ukrainian oblasts (regions) from 2020 to 2021. Treatment outcomes were evaluated using WHO definitions.

Chest X-ray as an alternative method of making a preliminary diagnosis in patients with susceptible or drug-resistant pulmonary tuberculosis.

Background: Making a preliminary diagnosis using X-ray methods for the study of resistant and resistant tuberculosis (TB) will help to make a preliminary diagnosis and determine further tactics for the treatment of TB, even with limited resources for microbiological diagnosis of drug resistance of TB. The present study was aimed at identifying chest X-ray differences between susceptible and resistant TB.

Methods: A prospective cohort study of data from all consecutive patients with culture-confirmed pulmonary TB admitted during the year to the Kharkiv TB Dispensary No.

Cytotoxicity of Hybrid Noble Metal-Polymer Composites.

The aim of the present research was to assess the cytotoxicity of gold and silver nanoparticles synthesized into dextran-graft-polyacrylamide (D-PAA) polymer nanocarrier, which were used as a basis for further preparation of multicomponent nanocomposites revealed high efficacy for antitumor therapy. The evaluation of the influence of Me-polymer systems on the viability and metabolic activity of fibroblasts and eryptosis elucidating the mechanisms of the proeryptotic effects has been done in the current research. The nanocomposites investigated in this study did not reduce the survival of fibroblasts even at the highest used concentration.

Assessing the Cytotoxicity of TiO Nanoparticles with a Different Ti(Ti)/Ti Ratio.

Titanium dioxide (TiO) nanoparticles are promising biomedical agents characterized by good biocompatibility. In this study, we explored the cytotoxicity of TiO nanoparticles with a different Ti(Ti)/Ti ratio and analyzed the efficiency of eryptosis indices as a tool in nanotoxicology. Two types of TiO nanoparticles (NPs) were synthesized by the hydrolysis of titanium alkoxide varying the nitric acid content in the hydrolysis mixture.

Antimicrobial Effects of Nanostructured Rare-Earth-Based Orthovanadates.

The search for novel antimicrobial agents is of huge importance. Nanomaterials can come to the rescue in this case. The aim of this study was to assess the cytotoxicity and antimicrobial effects of rare-earth-based orthovanadate nanoparticles.

UV Light-Activated GdYVO:Eu Nanoparticles Induce Reactive Oxygen Species Generation in Leukocytes Without Affecting Erythrocytes In Vitro.

Nanoparticles (NPs) have been reported to be promising enhancement agents for radiation therapy. The aim of the study was to assess the cytotoxicity of UV non-treated and UV pretreated GdYVO:Eu nanoparticles against erythrocytes and leukocytes by detecting eryptosis and reactive oxygen species (ROS) generation. Levels of intracellular ROS in erythrocytes and leukocytes using a ROS-sensitive dye 2',7'-dichlorodihydrofluorescein diacetate (H2DCFDA), as well as eryptosis rate utilizing annexin V staining, following direct exposure to UV-activated and nonactivated NPs were detected by flow cytometry.

Effectiveness of inhaled hypertonic saline application for sputum induction to improve Mycobacterium tuberculosis identification in patients with pulmonary tuberculosis.

Background: This study assessed the effectiveness and diagnostic significance of hypertonic saline sputum induction for improving Mycobacterium tuberculosis (MTB) detection.

Methods: A prospective, randomized, open, two-arm, comparative study on MTB identification effectiveness when using inhaled sodium chloride hypertonic solution was performed in patients diagnosed with pulmonary tuberculosis (TB). Patients were randomly assigned into two groups: group 1 (inhalation group) included patients who inhaled a 7% sodium chloride solution upon admission to the hospital, and group 2 (control group) coughed up their sputum as usual.

Neurocysticercosis with symptomatic epilepsy manifestation.

Aim To present a unique case of a 22-year-old male patient with symptomatic epilepsy manifestation on a background of neurocysticercosis (NCC). Methods An Indian student in Kharkiv, who lived in rural parts in India, presented with sudden episodes of seizure followed by severe headaches. Laboratory analyses and neurological status (MRI) were performed.

Impact of lung function on treatment outcome in patients with TB.

The potential association between the lung function status at baseline and TB treatment outcome has not been evaluated previously. We aimed to investigate the impact of lung function status at the time of TB diagnosis on treatment outcome in patients with pulmonary TB (PTB). A retrospective cohort study on data from all consecutive patients with culture-confirmed PTB and available spirometry test results admitted during the year 2016 to the Regional anti-TB dispensary no.

Tourette syndrome or PANDAS-a case report.

Tourette syndrome (TS), a relatively common disorder, has been gaining more attention during the past two decades because of an increased number of reports. Nevertheless, it is still not completely understood. Furthermore, a clinical entity called "pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections" (PANDAS) has been introduced, which describes a tic disorder, accompanied by psychiatric disorders such as obsessive compulsive disorder (OCD), after a streptococcal infection in childhood.

Treatment effectiveness and outcome in patients with a relapse and newly diagnosed multidrug-resistant pulmonary tuberculosis.

Aim To investigate the treatment effectiveness and outcome in patients with pulmonary tuberculosis relapse and newly diagnosed multidrug resistant pulmonary tuberculosis (MDR-TB). Methods A total of 240 pulmonary MDR-TB patients, including 114 ones with tuberculosis relapse and 126 cases of newly diagnosed pulmonary tuberculosis, were examined. Effectiveness of the basic antimycobacterial therapy course was evaluated based on the time to normalization of tuberculosis clinical manifestation, sputum culture and acid-fast bacilli stain conversion, cavity closure, disappearance of infiltrative and focal changes in the pulmonary tissue.

Introduction: In children with asthma, endothelial dysfunction signs are observed, and their extent depends on the severity of the disease. These changes are also present in remission. High level of soluble Vascular Cell Adhesion Molecule-1 (sVCAM-1) expression causes active adhesion of inflammatory cells and can indicate direct endothelium participation in development and supporting of chronic inflammation.
