PULMONARY TUBERCULOSIS PATIENTS DETECTED DURING MASS SCREENING AND BY REFERRAL TO MEDICAL UNITS

In Russia tuberculosis patients are detected during preventive mass screening and by self referral to medical units with clinical signs of the disease.Goal of the study: to compare pulmonary tuberculosis patients detected during mass screening and by self referral to medical units with clinical signs of the disease.Materials and methods: Data about 446 pulmonary tuberculosis patients treated in Republican TB Dispensary of Saransk in 2012-2014 were retrieved from Rosttsat Forms no. 8 and 33 and Russian Ministry of Health Reporting Forms (Edict 50). Statistica software was used for data processing.Results. Among 446 pulmonary tuberculosis patients detected in 2012-2014, the part of those detected during mass screening made ¾ out of total number, and those detected by self-referral made ¼, however the latter group of patients was significantly more dangerous from epidemiological point of view, since among them the part of those with long period of the disease before treatment start was higher, the positive sputum tests were more often observed as well as pulmonary cavities and primary MDR compared to the patients detected during mass screening.The obtained results point out at the need to focus on mass screening in the targeted groups of population concentrated around sources of infection

Q value and half-life of double-electron capture in Os-184

Os-184 has been excluded as a promising candidate for the search of neutrinoless double-electron capture. High-precision mass measurements with the Penning-trap mass spectrometer TRIGA-TRAP resulted in a marginal resonant enhancement with = -8.89(58) keV excess energy to the 1322.152(22) keV 0+ excited state in W-184. State-of-the-art energy density functional calculations are applied for the evaluation of the nuclear matrix elements to the excited states predicting a strong suppression due to the large deformation of mother and daughter states. The half-life of the transition in Os-184 exceeds T_{1/2} > 1.3 10^{29} years for an effective neutrino mass of 1 eV.Comment: accepted in Phys. Rev.

Integral estimation of systemic inflammatory response under sepsis

Currently, the most significant mediators of the systemic inflammatory response (SIR), specific to the development of critical states in sepsis, have the chaotic changes of concentrations in the blood. The solution to the problem is using integral indicators. A scoring scale of the SIR (0–16 points) is proposed based on the determination in the blood plasma of CRP, TNF-α, IL-6, IL-8 and IL-10. The scale was used in the survey of 167 patients with a diagnosis of sepsis (43 patients with sepsis according to definitions of “Sepsis-1 or 2” and 124 patients with sepsis according to the criteria of “Sepsis-3”); septic shock was verified in 31 cases and in 48 cases lethal outcomes were recorded. The association of SIR with critical complications of sepsis was revealed, especially under acute septic shock and in cases of a “second wave” (days 5–7) of critical complications. In contrast, prolonged/ subacute sepsis (more than 14 days) under tertiary peritonitis is characterised by a lesser dependence of the criticality of the state on the severity of SIR. The proposed scale is an open system and allows you to modify the range of used particular indicators that are compatible by pathogenetic and diagnostic significance. © 2020, Slovak Academy of Sciences.

Биохимические и морфологические показатели крови коров с субклинической формой мастита

This study aims to study the biochemical and morphological parameters of the blood of cows with subclinical mastitis. Experimental studies were conducted at Selyana LLC (Kuzbassky village, Kemerovo district, Kemerovo region) in 2021–2022. For this experiment, 12 cows were selected. Animals were divided into experimental (sick) and control (healthy) - 6 goals in each group. Animals were chosen according to the pair-analogues method, considering their live weight, breed, age at calving, milk yield, fat milk content, and physiological state. Body temperature was measured with a mercury thermometer with a scale graduated in Celsius from 34 to 42 ºС. The measurements were carried out for 5 min. The pulse rate was determined on the external maxillary artery for a minute. The number of exhalations calculated the frequency of respiratory movements. The same feeding and maintenance were organised for two groups of animals, i.e., they were in their usual conditions. In animals, after diagnostic tests for mastitis, blood was taken to study biochemical and morphological parameters. In sick animals, hyperproteinemia (87.43±0.82 g/l), low calcium content (87.43±0.82 g/l), and an increase in the level of phosphatase (156.15±0.50 U/l) were noted. In cows with mastitis, the number of leukocytes increased to 14.06 ± 2.29 × 1012/l. The average haemoglobin concentration in the erythrocyte was 27.77±0.43 in the control group and 27.87±0.21 g/dl in the experimental group. When studying the leukogram, the number of monocytes in the control group was 2.23±1.51, and in the group of animals with mastitis - 3.47±1.71%.Целью настоящего исследования является изучение биохимических и морфологических показателей крови коров с субклинической формой мастита. Экспериментальные исследования проводили в ООО «Селяна» (п. Кузбасский, Кемеровского района, Кемеровской области) в 2021–2022 гг. Для данного эксперимента было отобрано 12 коров. Животные были разделены на две группы – опытную (больные) и контрольную (здоровые) – по 6 голов в каждой группе. Животных отбирали по методу пар-аналогов с учетом их живой массы, породы, возраста в отелах, удоя, жирности молока, физиологического состояния. Температуру тела измеряли ртутным термометром со шкалой, градуированной по Цельсию от 34 до 42 ºС. Измерения проводили в течение 5 мин. Частоту пульса определяли на наружной челюстной артерии в течение минуты. Частоту дыхательных движений подсчитывали по количеству выдохов. Для двух групп животных было организовано одинаковое кормление и содержание, т. е. они находились в своих привычных условиях. У животных после диагностических исследований на мастит была взята кровь для изучения биохимических и морфологических показателей. У больных животных отмечали гиперпротеинемию (87,43±0,82 г/л), пониженное содержания кальция (87,43±0,82 г/л), повышение уровня фосфатазы (156,15±0,50 Ед/л). У коров, больных маститом, наблюдали повышение количества лейкоцитов до 14,06 ±2,29 · 1012/л. Средняя концентрация гемоглобина в эритроците составила в контрольной группе 27,77±0,43, в опытной – 27,87 ±0,21 г/дл.  Количество моноцитов, при изучении лейкограммы, в контрольной группе составило 2,23±1,51, в группе животных, больных маститом, – 3,47±1,71%

Homogenization of Variational Inequalities for the p-Laplace Operator in Perforated Media Along Manifolds

We address homogenization problems of variational inequalities for the p-Laplace operator in a domain of Rn (n ? 3, p ? [2, n)) periodically perforated by balls of radius O(??) where ? > 1 and ? is the size of the period. The perforations are distributed along a (n ? 1)-dimensional manifold ? , and we impose constraints for solutions and their fluxes (associated with the p-Laplacian) on the boundary of the perforations. These constraints imply that the solution is positive and that the flux is bounded from above by a negative, nonlinear monotonic function of the solution multiplied by a parameter ? ?? , ? ? R and ? is a small parameter that we shall make to go to zero. We analyze different relations between the parameters p, n, ?, ? and ?, and obtain homogenized problems which are completely new in the literature even for the case p = 2.This work has been partially supported by the Spanish grant MINECO:MTM2013-44883-P

Саранска в 2012-2014 гг., получены из отчетных форм Росттата № 8 и 33 и отчетных форм Минздрава России (приказ № 50). Для обработки данных применены стандартные пакеты статистических программ Statistica.Результаты. Среди 446 больных туберкулезом легких, выявленных в 2012-2014 гг., доля выявленных при периодических осмотрах составляла ¾ от их общего числа, а при обращении в медицинские организации с клиническими проявлениями болезни - ¼, однако именно эти пациенты были значительно опаснее в эпидемическом плане, поскольку среди них была достоверно выше доля лиц с длительными периодами заболевания до начала лечения и достоверно чаще обнаруживались бактериовыделение, полости распада в легких и первичная МЛУ МБТ по сравнению с пациентами, выявленными при периодических осмотрах. Полученные результаты свидетельствуют о необходимости фокусирования массовых периодических осмотров на целевых группах населения, сконцентрированных вокруг очагов инфекции

Introduction. The COVID-19 pandemic was announced by WHO in February 2020. In the Kaliningrad region, the first case (imported) was registered in early March 2020, the beginning of the epidemic increase fell on the 14th week. 2020, and the peak incidence was reached in the 22nd week of the year, after which there was a steady decrease in the number of cases. The study of population immunity was carried out at the 32nd week during the period of the lowest level of intensity of the epidemic process.Purpose of the study. Assessment of the assessment of the level of population immunity to the SARS-CoV-2 virus among the population of the Kaliningrad region during the period of the epidemic incidence of the population of COVID-19.Materials and methods. The study was carried out as part of the first stage of the Rospotrebnadzor program to assess population immunity to SARS-CoV-2 among the population of the Russian Federation. The selection of volunteers for the study was carried out by a questionnaire survey and subsequent randomization. The analysis includes the results of a survey of 2675 people. The number of volunteers in age groups ranged from 314 to 493 people. The results obtained were processed by the methods of variation statistics.Results. The results obtained showed that the average seroprevalence in the population was 50.2%, while the highest seroprevalence was found in the child age group 1-17 years (66.9%) and among persons aged 18-29 (57.0). No significant gender differences were found (men – 48,3 ± 1,6%, women – 51,1 ± 1,1%). The distribution of the proportion of seropositive people in the settlements of the region varied from 33,9% to 59.6%. The largest share of seroprevalence in the representative samples was found among people engaged in art / creativity (55,3%), the smallest – among educational workers (42,0%). Among COVID-19 convalescents, the level of humoral immunity reached 94,6%. Most of the seropositive volunteers (95,2%) did not have any symptoms of COVID-19, that is, they belonged to the category of asymptomatic carriers.Output. The results of a survey of a representative cohort of volunteers in the Kaliningrad region showed that they are characterized by a high level of population immunity, which makes it possible to expect a decrease in.Введение.

Достоверных половых различий не установлено (мужчины – 48,3±1,6%, женщины – 51,1±1,1%). Распределение доли серопозитивных по населенным пунктам области варьировало от 33,9% до 59,6%. Наибольшая доля серопревалентных в репрезентативных выборках выявлена среди лиц, занятых искусством/творчеством (55,3%), наименьшая – среди работников образования (42,0%). Среди реконвалесцентов COVID-19 уровень гуморального иммунитета достиг 94,6%. Большая часть серопозитивных волонтеров (95,2%) не имела каких-либо симптомов COVID-19, то есть относилась к категории бессимптомных носителей.Выводы. Результаты обследования репрезентативной когорты волонтеров Калининградской области показали, что для них характерен высокий уровень популяционного иммунитета, позволяющий ожидать снижения напряженности эпидемического процесса.

Population genomics of post-glacial western Eurasia.

Western Eurasia witnessed several large-scale human migrations during the Holocene <sup>1-5</sup> . Here, to investigate the cross-continental effects of these migrations, we shotgun-sequenced 317 genomes-mainly from the Mesolithic and Neolithic periods-from across northern and western Eurasia. These were imputed alongside published data to obtain diploid genotypes from more than 1,600 ancient humans. Our analyses revealed a 'great divide' genomic boundary extending from the Black Sea to the Baltic. Mesolithic hunter-gatherers were highly genetically differentiated east and west of this zone, and the effect of the neolithization was equally disparate. Large-scale ancestry shifts occurred in the west as farming was introduced, including near-total replacement of hunter-gatherers in many areas, whereas no substantial ancestry shifts happened east of the zone during the same period. Similarly, relatedness decreased in the west from the Neolithic transition onwards, whereas, east of the Urals, relatedness remained high until around 4,000 BP, consistent with the persistence of localized groups of hunter-gatherers. The boundary dissolved when Yamnaya-related ancestry spread across western Eurasia around 5,000 BP, resulting in a second major turnover that reached most parts of Europe within a 1,000-year span. The genetic origin and fate of the Yamnaya have remained elusive, but we show that hunter-gatherers from the Middle Don region contributed ancestry to them. Yamnaya groups later admixed with individuals associated with the Globular Amphora culture before expanding into Europe. Similar turnovers occurred in western Siberia, where we report new genomic data from a 'Neolithic steppe' cline spanning the Siberian forest steppe to Lake Baikal. These prehistoric migrations had profound and lasting effects on the genetic diversity of Eurasian populations
