    Objective: Π’ΠΎ search for the most difficult areas of the differential diagnosis of TBI, the definition of statistically significant differential diagnosis criteria for designated areas - the first stage of the development of decision support systems of medical solutions in this area. Materials and Methods: The study consisted of several stages. In the first stage was retrospectively analyzed 2,156 cases of moderate and severe traumatic brain injury complicated directions to find the differential diagnosis of traumatic brain injury. In the second stage search criteria performed differential diagnosis of brain injuries in the directions indicated by the first stage. Criteria marked with a solid analysis of 726 prospective cases that were 6 groups of comparison. Results: were identified statistically valid differential diagnostic criteria for each of the most difficult areas identified in the first stage. Signs formed from the most simple study of clinical and instrumental tests. Conclusion: The clinical and statistical principle of formation of differential criteria on the most important areas of the differential diagnosis of TBI, allowed to identify statistically significant criteria that can be used as the basis for the creation of funds to support medical decision-making.ЦСль: поиск Π½Π°ΠΈΠ±ΠΎΠ»Π΅Π΅ слоТных Π½Π°ΠΏΡ€Π°Π²Π»Π΅Π½ΠΈΠΉ Π΄ΠΈΡ„Ρ„Π΅Ρ€Π΅Π½Ρ†ΠΈΠ°Π»ΡŒΠ½ΠΎΠΉ диагностики ЧМВ, ΠΎΠΏΡ€Π΅Π΄Π΅Π»Π΅Π½ΠΈΠ΅ статистичСски Π·Π½Π°Ρ‡ΠΈΠΌΡ‹Ρ… ΠΊΡ€ΠΈΡ‚Π΅Ρ€ΠΈΠ΅Π² Π΄ΠΈΡ„Ρ„Π΅Ρ€Π΅Π½Ρ†ΠΈΠ°Π»ΡŒΠ½ΠΎΠΉ диагностики ΠΏΠΎ ΠΎΠ±ΠΎΠ·Π½Π°Ρ‡Π΅Π½Π½Ρ‹ΠΌ направлСниям - ΠΊΠ°ΠΊ ΠΏΠ΅Ρ€Π²Ρ‹ΠΉ этап Ρ€Π°Π·Ρ€Π°Π±ΠΎΡ‚ΠΊΠΈ систСмы ΠΏΠΎΠ΄Π΄Π΅Ρ€ΠΆΠΊΠΈ принятия Π²Ρ€Π°Ρ‡Π΅Π±Π½ΠΎΠ³ΠΎ Ρ€Π΅ΡˆΠ΅Π½ΠΈΡ ΠΏΠΎ Π΄Π°Π½Π½ΠΎΠΌΡƒ Π½Π°ΠΏΡ€Π°Π²Π»Π΅Π½ΠΈΡŽ.

    Heavy-meson physics and flavour violation with a single generation

    Full text link
    We study flavour-violating processes which involve heavy B- and D-mesons and are mediated by Kaluza-Klein modes of gauge bosons in a previously suggested model where three generations of the Standard Model fermions originate from a single generation in six dimensions. We find the bound on the size R of the extra spatial dimensions 1/R>3.3 TeV, which arises from the three-body decay B_s to K mu e. Due to the still too low statistics this bound is much less stringent than the constraint arising from K to mu e, 1/R>64 TeV, which was found in a previous work (Frere et al., JHEP, 2003). Nevertheless, we argue that a clear signature of the model would be an observation of K to mu e and B_s to K mu e decays without observations of other flavour and lepton number changing processes at the same precision level.Comment: 15 page

    In 2017, the European Society of Cardiology outlined the importance of the problem of diagnosing myocardial ischemia-reperfusion injury following coronary artery bypass grafting. Myocardial injury can be accompanied by a critical decline in the cardiac index and an increase in cardiac troponin I plasma levels. The prognostic value troponin I elevation after coronary artery bypass grafting is poorly understood. Objective: to determine the prognostic value of troponin I plasma levels in relation to a fall in the cardiac index after coronary artery bypass grafting (CABG). Task: To determine the probability the cardiac index falling below 2.2 for troponin I levels in the first hours, and on days 1, 2, 3, 4 after CABG. Materials and methods. The single-center, non-randomized prospective study, running from 2016 to 2019, included 336 patients admitted for elective surgical treatment of coronary artery disease. The CABG patients were divided into three observation groups: off-pump (n = 175), on-pump (n = 128), and pump-assisted (n = 33). Troponin I levels were measured in the first hours, and on days 1, 2, 3, 4 after surgery using the Pathfast Compact immunoassay analyzer. Cardiac index was measured by invasive method. Results. In patients with a cardiac index higher than 2.2, troponin I level did not exceed 0.5 ng/mL in the off-pump group, 6 ng/mL in the on-pump group, and 3.5 ng/mL in the pump-assisted group. Patients with cardiac index lower than 2.2 have comparable troponin I levels in all groups - 21 ng/mL. Troponin I thresholds on day 1 after surgery, which, when exceeded, was associated with the likelihood of the cardiac index falling below 2.2, was 3.78 ng/mL in the off-pump group, 9.67 ng/mL in the on-pump group and 17.06 ng/mL in the pump-assisted group. Conclusion. After off-pump CABG, clinically significant myocardial injury should be expected at lower troponin I levels (3.78 ng/mL) than after on-pump CABG (9.67 ng/mL) and pump-assisted CABG (14.7 ng/mL).Π’ 2017 Π³ΠΎΠ΄Ρƒ ЕвропСйскоС общСство ΠΊΠ°Ρ€Π΄ΠΈΠΎΠ»ΠΎΠ³ΠΎΠ² ΠΎΠ±ΠΎΠ·Π½Π°Ρ‡ΠΈΠ»ΠΎ Π²Π°ΠΆΠ½ΠΎΡΡ‚ΡŒ ΠΏΡ€ΠΎΠ±Π»Π΅ΠΌΡ‹ диагностики ΠΈΡˆΠ΅ΠΌΠΈΡ‡Π΅ΡΠΊΠΈ-Ρ€Π΅ΠΏΠ΅Ρ€Ρ„ΡƒΠ·ΠΈΠΎΠ½Π½ΠΎΠ³ΠΎ поврСТдСния ΠΌΠΈΠΎΠΊΠ°Ρ€Π΄Π° послС ΠΎΠΏΠ΅Ρ€Π°Ρ†ΠΈΠΉ ΠΊΠΎΡ€ΠΎΠ½Π°Ρ€Π½ΠΎΠ³ΠΎ ΡˆΡƒΠ½Ρ‚ΠΈΡ€ΠΎΠ²Π°Π½ΠΈΡ.

    Development and validation of an ultra?performance liquid chromatography quadrupole time of flight mass spectrometry method for rapid quantification of free amino acids in human urine

    An ultra-performance liquid chromatography quadrupole time of flight mass spectrometry (UPLC-qTOFMS)method using hydrophilic interaction liquid chromatography was developed and validated for simultaneous quantification of 18 free amino acids in urine with a total acquisition time including the column re-equilibration of less than 18 min per sample. This method involves simple sample preparation steps which consisted of 15 times dilution with acetonitrile to give a final composition of 25 % aqueous and 75 % acetonitrile without the need of any derivatization. The dynamic range for our calibration curve is approximately two orders of magnitude (120-fold from the lowest calibration curve point) with good linearity (r2 ? 0.995 for all amino acids). Good separation of all amino acids as well as good intra- and inter-day accuracy (<15 %) and precision (<15 %) were observed using three quality control samples at a concentration of low, medium and high range of the calibration curve. The limits of detection (LOD) and lower limit of quantification of our method were ranging from approximately 1–300 nM and 0.01–0.5 Β΅M, respectively. The stability of amino acids in the prepared urine samples was found to be stable for 72 h at 4 Β°C, after one freeze thaw cycle and for up to 4 weeks at ?80 Β°C. We have applied this method to quantify the content of 18 free amino acids in 646 urine samples from a dietary intervention study. We were able to quantify all 18 free amino acids in these urine samples, if they were present at a level above the LOD. We found our method to be reproducible (accuracy and precision were typically <10 % for QCL, QCM and QCH) and the relatively high sample throughput nature of this method potentially makes it a suitable alternative for the analysis of urine samples in clinical setting

    Introduction. Despite resounding success in treatment of patients with coronary heart disease (CHD), researchers are yet unable to significantly reduce mortality in this disease. With this in mind, there are ongoing studies everywhere, which are aimed at investigating new techniques in order to boost the efficiency of existing standards. One of such promising techniques is cell/regenerative therapy with autologous bone marrow mononuclear cells (ABMMCs). However, even though ABMMCs have been studied for more than 10 years, there are no unambiguous data yet on several issues. Objective: to evaluate the outcome of ABMMC transplantation during coronary artery bypass grafting (CABG) surgery in combined treatment of CHD. Materials and methods. The data of 408 patients admitted to the clinic from 2013 to 2016 for planned surgical treatment of CHD were analyzed. The work included 117 people based on the design of the study. Patients were randomized in 3 groups: Group 0 (control group) – CABG surgery and intramyocardial injection of 0.9% NaCl solution, Group 1 – CABG surgery and intramyocardial injection of ABMMCs, Group 2 – CABG surgery, intramyocardial and intra-graft injection of ABMMCs. The dynamics was assessed 12 months later – functional class of angina pectoris and heart failure, echocardiography, speckle tracking (assessment of the degree of myocardial deformation), treadmill test, 6-minute walk test, daily ECG monitoring, quality of life questionnaires, coronary angiography. Qualitative indicators were calculated using the Pearson’s chi-squared test and Fisher criteria. Quantitative indicators were calculated using the Kruskal–Wallis and Wilcoxon tests. Factor analysis was used to identify certain severity factors and to study data homogeneity. Discriminant analysis was performed to investigate the leading characteristics that determine differentiation between the groups. For analysis of variance, taking into account various factors, the model of variance analysis for dependent samples – Repeated Measures ANOVA – was used. Results. In the observation groups, an improvement in both systolic and diastolic myocardial function was universally noted. A six-minute walk test showed statistically significant increase in Groups 1 and 2 compared with the control Group 0 – 315.06 Β± 17.6 (433.54 Β± 20.6), Group 1 – 319.8 Β± 24.5 (524.4 Β± 28.7), Group 2 – 329.9 Β± 25.3 (452.7 Β± 29.7) meters. A significant decrease in the functional class of exertional angina pectoris in Groups 1 and 2 was noted unlike in the control group. The percentage of functioning coronary shunts after a 12-month follow-up period was 87.6% in Group 0. In Groups 1 and 2, this ratio was 96.2% and 97.3%, respectively. Predictors of overall effectiveness were identified: smoking, initial diastolic myocardial dysfunction, left ventricular ejection fraction. Conclusion. In addition to surgical treatment of coronary heart disease, ABMMC transplantation can improve myocardial contractility, boost exercise tolerance, and increase the duration of the functioning of coronary shunts at the follow-up period of 12 months. The study showed the need for stage-by-stage analytical calculations with the aim of possible correction of further work.Π’Π²Π΅Π΄Π΅Π½ΠΈΠ΅.

    Metabolic Linkage and Correlations to Storage Capacity in Erythrocytes from Glucose 6-Phosphate Dehydrogenase-Deficient Donors

    No full text
    ObjectiveIn glucose 6-phosphate dehydrogenase (G6PD) deficiency, decreased NADPH regeneration in the pentose phosphate pathway and subnormal levels of reduced glutathione result in insufficient antioxidant defense, increased susceptibility of red blood cells (RBCs) to oxidative stress, and acute hemolysis following exposure to pro-oxidant drugs and infections. Despite the fact that redox disequilibrium is a prominent feature of RBC storage lesion, it has been reported that the G6PD-deficient RBCs store well, at least in respect to energy metabolism, but their overall metabolic phenotypes and molecular linkages to the storability profile are scarcely investigated.MethodsWe performed UHPLC-MS metabolomics analyses of weekly sampled RBC concentrates from G6PD sufficient and deficient donors, stored in citrate phosphate dextrose/saline adenine glucose mannitol from day 0 to storage day 42, followed by statistical and bioinformatics integration of the data.ResultsOther than previously reported alterations in glycolysis, metabolomics analyses revealed bioactive lipids, free fatty acids, bile acids, amino acids, and purines as top variables discriminating RBC concentrates for G6PD-deficient donors. Two-way ANOVA showed significant changes in the storage-dependent variation in fumarate, one-carbon, and sulfur metabolism, glutathione homeostasis, and antioxidant defense (including urate) components in G6PD-deficient vs. sufficient donors. The levels of free fatty acids and their oxidized derivatives, as well as those of membrane-associated plasticizers were significantly lower in G6PD-deficient units in comparison to controls. By using the strongest correlations between in vivo and ex vivo metabolic and physiological parameters, consecutively present throughout the storage period, several interactomes were produced that revealed an interesting interplay between redox, energy, and hemolysis variables, which may be further associated with donor-specific differences in the post-transfusion performance of G6PD-deficient RBCs.ConclusionThe metabolic phenotypes of G6PD-deficient donors recapitulate the basic storage lesion profile that leads to loss of metabolic linkage and rewiring. Donor-related issues affect the storability of RBCs even in the narrow context of this donor subgroup in a way likely relevant to transfusion medicine

    Aim: to assess the safety of transplantation of autologous bone marrow mononuclear cells when performing coronary artery bypass grafting in the combined treatment of ischemic heart disease in patients with coronary and heart failure.Materials and methods. During the period from 2013 to 2016 years 117 patients, who meet the established criteria, were included in the work. Randomization was performed in observation groups: group 0 -control group (coronary artery bypass grafting (CABG) and intramyocardial administration of a 0.9% NaCl solution), group 1 - CABG surgery and intramyocardial administration of autologous bone marrow mononuclear cells (ABMMS), group 2 - CABG surgery and intramyocardial and intragraft administration of ABMMS. Clinical, laboratory - CPK MB, myoglobin, troponin I, HCT, Hb, K +, ABC; instrumental (stress tests, echocardiography, speckle tracking, coronary angiography) data were evaluated in these groups. The analysis of the frequency of postoperative complications (hydrothorax, hydropericardium, rhythm disturbances) was performed; the length of stay in the intensive care unit, the length of stay in the hospital and other indicators. After 6 and 12 months, the overall mortality was assessed, major cardiac events - the development of acute myocardial infarction, ventricular arrhythmias, oncological alertness. Number in international register clinical trials Clinical Trial. gov Identifier: NCT02059512.Results. Statistical analysis showed no statistically significant differences in the observation groups for the compared criteria.Conclusion. Transplantation of autologous bone marrow mononuclear cells during aorto-coronary bypass surgery in the combined treatment of coronary heart disease is a safe method
