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.

Article Synopsis
  • The study investigates cancer resistance in centenarians, suggesting that they have better DNA repair mechanisms due to higher levels of the ATM gene.
  • Higher ATM mRNA expression in lymphoblastoid cell lines (LCLs) from centenarians was significantly observed compared to younger women, indicating a potential link to longevity and reduced cancer rates.
  • The research also notes lower levels of a specific microRNA (hsa-miR-181a-5p), which targets ATM, in centenarians, suggesting it may contribute to their enhanced DNA repair capabilities and protection against age-related diseases.

The purpose of this work was to define dependence of maintenance of myeloperoxidase (MPO) in plasma of blood of patients by the acute infarct of myocardium from the state of oxygen metabolism of neutrophils, which was estimated on activity of myeloperoxidases, superoxid-anion and catalase in cells and on maintenance by peroxigens. 19 is inspected practically healthy volunteers and 56 patients with the the acute infarct of myocardium. The got results testify that maintenance of MPO in plasma of blood of patients with acute infarct of myocardium depends on the functional state of neutrophils, which, in its turn, is related to the clinical features of patients.

We studied the content of myeloperoxidase in plasma of blood, which is a new additional marker of the metabolic activity of phagocytes and the activity of inflammation in patientes with the acute infarct of myocardium and possibility of its correction of Korvitin. We inspected 15 practically healthy persons in which the content of myeloperoxidase was 74,5±16,3 ng/ml, 13 patients with a stable stenocardia (the conent of myeloperoxidase was 218,4±30,9 ng/ml) and 60 patients with acute infarct of myocardium (the content of myeloperoxidase was 606,0±59,3 ng/ml at the beginning of therapy) in the dynamics of treatment. In patients accepting standard treatment (without application of Korvitin), the content of myeloperoxidase was unchanged during 7 days of treatment.

Aiming to assess the relationships between renal function and ST-segment elevation myocardial infarction (MI) clinical course and remote outcomes in patients with preserved systolic left ventricular (LV) function (LV ejection fraction > 40%) estimated glomerular filtration rates (eGFR) were evaluated on 1st and 3rd -10th MI day (n = 491). On 3rd-10th day of MI in patients with acute heart failure (HF) symptoms on admission day (1st group, n = 153) eGFR < 70 ml/min x per body surface unit was independent marker of re-infarction (Hazzard Ratio (HR) with 95% confidence intervals (95% CI) = 4,08 [1,72 -11,73], P < 0,01) and cardiovascular death (CVD) (HR [95% CI] = 3,61 [1,09 - 11,99], P = <0,05) during three years of follow-up. In patient without acute HF (2nd group, n = 338) eGFR < 68 ml/min was predictive of CVD within three years post-MI (HR [95% CI] = 7,13 [2,06 - 24,74], P = 0,002).
