Intensive Care Outcomes and Differences Between Survivors and Deceased Patients in a Terminal Coma: A Retrospective Observational Study

Background. Early prognosis for the outcome of a coma-induced critical condition is central to selecting an optimal tactic for patient management. This question remains insufficiently studied, thus justifying the task of identifying significant criteria for differences in terminal coma patients (stage III, irreversible) who died and those recovered to different levels of consciousness.Objectives. To analyze the intensive care outcomes for patients in a terminal coma and to establish differences between the initial state of patients who have died and those who have recovered to different levels of consciousness.Methods. A retrospective observational study was conducted on 210 patients aged 21 to 65 hospitalized in the Anesthesiology and Resuscitation Unit of Ochapovsky Regional Clinical Hospital No. 1 (Krasnodarsky Krai) with a diagnosis of terminal coma in the period from 2010 to 2015. The study did not include patients with pregnancy, histologically-confirmed malignancies, cardiovascular diseases (NYHA classes III-IV, according to the New York Heart Association Functional Classification), terminal liver cirrhosis and chronic kidney disease at the stage of hemodialysis. Depending on the critical condition outcome, the admitted patients were divided into groups: group 1 (n = 101) — patients with adverse outcomes; group 2 (n = 109) — patients with relatively favorable outcomes (recovery to a level of consciousness at score 4 and higher, according to The Glasgow Coma Scale). The condition was assessed with referring to available clinical data. Statistical processing of the obtained study results was carried out via nonparametric techniques using Microsoft Excel 10 (Microsoft, USA) and Statistica 6.0 (StatSoft, USA).Results. The mortality structure against the background of a terminal coma in the following diagnosis: polytrauma — 54%, hemorrhagic stroke — 56%, isolated traumatic brain injury — 37%, acute cerebrovascular accidents (ischemic type) — 33% and acute posthypoxic dyscirculatory encephalopathy — 11%. Intergroup differences between the deceased and survivors were obtained in the following parameters: age (older with unfavorable outcome); base deficit — by 52%; glucose — by 47.6%; troponin — by 47.1%; potassium — by 13.7% and daily diuresis — by 27.5%.Conclusion. The obtained results are likely to be used in a combination of clinical, instrumental and laboratory examinations in order to provide early detection of the risk group with an adverse outcome

Отдельные аспекты эффективности цифровизации растениеводства в Республике Беларусь

Digitalization, or digital transformation, is an innovative approach to solving the key task of agricultural production in the Republic of Belarus – increasing / maintaining the profitability of crop production. Digitalization makes it possible to bring crop production to a new level of development, providing a fundamental restructuring of the decision-making and implementation of agro-technological operations, reducing risks and expanding possibilities of sustainable and efficient crop production. Efficiency of digitalization of crop production is considered in relation to certain aspects of an average agricultural organization in the Republic of Belarus. The following main interrelated areas of digitalization in crop production have been identified: soil-and-agrochemical analysis, precision arable farming, prediction of the diseases and pests of crops. Due to significant growth of energy prices nowadays (basic elements in the formation of the final cost of crop production), efficiency of digitalization was assessed not directly in terms of value, but in reducing the costs of growing products and in saved crops. The greatest effect, according to the results of the assessment, is expected from such areas of digitalization as soiland-agrochemical analysis, as well as prediction of the diseases and pests of agricultural crops. The results of soil-and-agrochemical analysis can be used to improve the soil fertility – a vital condition for long-term increase of crop yields. Prediction of the diseases and pests of crops is one of the main elements of comprehensive protection of crops – a large reserve for increasing crop production. At the same time, despite the positive aspect of digitalization in agricultural branch of the Republic of Belarus, it is rather a labor-intensive process together with the high cost of necessary equipment and software, as well as the use complexity.Цифровизация, или цифровая трансформация, является инновационным подходом решения ключевой задачи сельскохозяйственного производства Республики Беларусь – повышения/поддержания рентабельности растениеводства. Цифровизация позволяет вывести растениеводство на новый уровень развития, обеспечивая фундаментальную перестройку принятия управленческих решений и выполнения агротехнологических операций, снижая риски и расширяя возможности ведения устойчивого и эффективного растениеводства. Рассмотрена эффективность цифровизации растениеводства применительно к отдельным аспектам среднестатистической сельхозорганизации Республики Беларусь. Выделены следующие основные взаимосвязанные направления цифровизации растениеводства: почвенно-агрохимический анализ, точное земледелие, прогнозирование болезней и вредителей сельхозкультур. В связи со значительным ростом в настоящее время цен на энергоресурсы (базовые элементы формирования конечной стоимости продукции растениеводства) эффективность цифровизации оценивалась не в стоимостном выражении, а в снижении издержек на выращивание продукции растениеводства и в сохраненном урожае. По результатам оценки наибольший эффект ожидается от таких направлений цифровизации, как почвенно-агрохимический анализ, а также прогнозирование болезней и вредителей сельхозкультур. Результаты почвенно-агрохимического анализа могут быть использованы при повышении плодородия почв – необходимом условии увеличения урожайности сельхозкультур в долгосрочной перспективе. Прогнозирование болезней и вредителей сельхозкультур является одним из основных элементов их комплексной защиты – большим резервом увеличения продукции растениеводства. Вместе с тем, несмотря на перспективность цифровизации сельскохозяйственной отрасли Республики Беларусь, она является достаточно трудоемким процессом в совокупности с высокой стоимостью необходимого оборудования и программного обеспечения, а также сложностью их использования

High-Resolution Functional Mapping of the Venezuelan Equine Encephalitis Virus Genome by Insertional Mutagenesis and Massively Parallel Sequencing

We have developed a high-resolution genomic mapping technique that combines transposon-mediated insertional mutagenesis with either capillary electrophoresis or massively parallel sequencing to identify functionally important regions of the Venezuelan equine encephalitis virus (VEEV) genome. We initially used a capillary electrophoresis method to gain insight into the role of the VEEV nonstructural protein 3 (nsP3) in viral replication. We identified several regions in nsP3 that are intolerant to small (15 bp) insertions, and thus are presumably functionally important. We also identified nine separate regions in nsP3 that will tolerate small insertions at low temperatures (30°C), but not at higher temperatures (37°C, and 40°C). Because we found this method to be extremely effective at identifying temperature sensitive (ts) mutations, but limited by capillary electrophoresis capacity, we replaced the capillary electrophoresis with massively parallel sequencing and used the improved method to generate a functional map of the entire VEEV genome. We identified several hundred potential ts mutations throughout the genome and we validated several of the mutations in nsP2, nsP3, E3, E2, E1 and capsid using single-cycle growth curve experiments with virus generated through reverse genetics. We further demonstrated that two of the nsP3 ts mutants were attenuated for virulence in mice but could elicit protective immunity against challenge with wild-type VEEV. The recombinant ts mutants will be valuable tools for further studies of VEEV replication and virulence. Moreover, the method that we developed is applicable for generating such tools for any virus with a robust reverse genetics system

Polymorphisms at two enzyme loci (Sod and Odh) in populations of the Amur sleeper, Perccottus glenii (Pisces, Eleotrididae), from its native range and the colonized area: the effect of introduction on genetic variation

In the first half of the 20th century small founder groups of the Amur sleeper, Perccottus glenii, have been transferred from their native range in the Far East to some regions of the European part of Russia. In order to investigate the consequences of the introductions, 15 Far East populations and 11 European populations, that originated from two transfers, were studied for their variability on two enzyme loci (Sod and Odh) using polyacrylamide gel electrophoresis. For both loci, divergence between populations and heterozygosity in the populations were higher in the colonized regions than in the native range. Heterozygote advantage in small founder populations seems to be a factor resisting genetic drift and determining the changes observed in the genetic structure of the introduced populations

L'ansia da lingua straniera è la sensazione di disagio, preoccupazione, nervosismo e apprensione sperimentata nell'apprendimento o nell'uso di una seconda lingua o di una lingua straniera. La consapevolezza delle reazioni emotive degli studenti li aiuta a raggiungere i loro obiettivi nel processo di apprendimento. Anche ricercatori, metodologi e insegnanti dovrebbero avere questa consapevolezza per aiutare meglio gli studenti. L'ansia della lingua è comune nell'apprendimento di una lingua straniera. La maggior parte degli studenti afferma di avere un blocco mentale nell'apprendimento di una lingua straniera, anche se ha una forte motivazione e sebbene faccia un ottimo lavoro in altre situazioni di apprendimento. Nella maggior parte dei casi, la causa di questo fenomeno è l'ansia da lingua straniera, che impedisce il successo nell’apprendimento. L'ansia è una sensazione soggettiva di tensione, suscettibilità e nervosismo associata all'eccitazione del sistema nervoso autonomo. Gli individui che hanno ansia tendono ad evitare situazioni che l’hanno causata in passato. Proprio come l'ansia impedisce ad alcuni di svilupparsi con successo nella scienza o nella matematica, allo stesso modo rende stressante l'apprendimento di una lingua straniera, specialmente all'interno di istituzioni educative generali (scuole, università, etc.). Quando l'ansia è limitata alla situazione dell'apprendimento linguistico, si riferisce alla categoria di una specifica reazione ansiosa. Gli psicologi usano il termine "specifica reazione ansiosa" per differenziare gli individui che hanno ansia in una varietà di situazioni da quelli che la sperimentano solo in situazioni specifiche. I ricercatori hanno identificato diversi tipi di reazioni ansiose specifiche, ad esempio, legati all'esecuzione di compiti di studio, come test, o allo studio di alcune materie accademiche, come la matematica o argomenti del ciclo di scienze naturali
