ИСПОЛЬЗОВАНИЕ НОВОГО ПРИЛОЖЕНИЯ ДЛЯ МОБИЛЬНЫХ УСТРОЙСТВ «CAPSTESIA» ДЛЯ ОПРЕДЕЛЕНИЯ ПОТРЕБНОСТИ В ИНФУЗИЯХ

As a rule, methods evaluating the need and volume of fluid therapy are expensive, they require relevant equipment and it is not always available in hospitals; therefore it has been proposed to use mobile devices with Capstesia software to capture the image of the arterial pressure curve from the monitor screen and to analyze it in order to determine the variability of the pulse pressure (PPV). Materials and subjects. The efficiency of defining the need for fluid therapy using Capstesia was assessed in the clinical settings. 95 integrated measurements were performed in 19 patients with septic shock, who had the catheter installed to monitor the fluid therapy for trans-pulmonary thermodilution; and the PiCCO2 monitor was used. Simultaneously, the test with the volemic load (VLT) was conducted and PPV was tested with the aid of Capstesia. Results. The analysis revealed significantly higher mean differences and ranges of levels' consistency when testing PPV by Capstesia, in which the error rate was also higher than the acceptable level and it made 56%, whereas the method of VLT had only 20% of errors and significantly smaller mean difference and ranges of consistency levels. Методы оценки необходимости и объема инфузионной терапии, как правило, дорогостоящи, требуют наличия соответствующего оборудования и не всегда доступны для рядовых клиник, поэтому предложено использование гаджета с программой «Capstesia» для захвата изображения кривой артериального давления с экрана монитора и ее анализа для определения вариабельности пульсового давления (PPV). Материал и методы. Проведена проверка эффективности определения потребности в инфузиях с помощью метода «Capstesia» в клинических условиях. Выполнено 95 комплексных измерений у 19 больных с септическим шоком, которым для контроля проведения инфузионной терапии устанавливали катетер для транспульмональной термодилюции и использовали монитор «PiCCO2». Одновременно проводили пробу с волемической нагрузкой (ПВН) и определение PPV при помощи «Capstesia». Результаты. Анализ выявил значительно более высокие показатели средней разности и диапазон уровней согласованности при использовании определения PPV при помощи «Capstesia», при котором процент ошибок также был выше приемлемого уровня – 56%, тогда как метод ПВН имел только 20% ошибок, значительно меньшую среднюю разность и диапазон уровней согласованности.

Мультимодальный подход к дифференциальной диагностике метастатического поражения при раке молочной железы: описание клинического случая

Modern complex and morphological diagnostics are important conditions for optimal therapeutic algorithm development if breast cancer relapse is suspected. This article shows the importance of a multimodal approach to the differential diagnostics of secondary tumor lesions. Modern clinical and radiologic evaluation, interventional technologies, trustworthy morphological investigstion and multidisciplinary teamwork facilitated to make correct diagnosis of sarcoidosis in patient with lesions suspicious for breast cancer relapse and schedule correct treatment. Современная комплексная диагностика и качественный морфологический диагноз являются важными условиями выработки оптимального лечебного алгоритма при подозрении на рецидив рака молочной железы. На собственном клиническом примере показана важность мультимодального подхода к дифференциальной диагностике вторичного опухолевого поражения. Благодаря современной клинико-рентгенологической диагностике, интервенционным технологиям, качественному морфологическому анализу и тесному взаимодействию всех членов мультидисциплинарной команды у пациентки с подозрением на рецидив рака молочной железы удалось верифицировать поражение неопухолевого генеза (саркоидоз) и спланировать правильную тактику лечения.

THE NOVEL MOBILE DEVICE APPLICATION OF CAPSTESIA AIMED TO DEFINE THE NEED FOR FLUID THERAPY

Instrumental analysis of bacterial cells using vibrational and emission Mössbauer spectroscopic techniques

In biosciences and biotechnology, the expanding application of physicochemical approaches using modern instrumental techniques is an efficient strategy to obtain valuable and often unique information at the molecular level. In this work, we applied a combination of vibrational (Fourier transform infrared (FTIR), FT-Raman) spectroscopic techniques, useful in overall structural and compositional analysis of bacterial cells of the rhizobacterium Azospirillum brasilense, with 57Co emission Mössbauer spectroscopy (EMS) used for sensitive monitoring of metal binding and further transformations in live bacterial cells. The information obtained, together with ICP-MS analyses for metals taken up by the bacteria, is useful in analysing the impact of the environmental conditions (heavy metal stress) on the bacterial metabolism and some differences in the heavy metal stress-induced behaviour of non-endophytic (Sp7) and facultatively endophytic (Sp245) strains. The results show that, while both strains Sp7 and Sp245 take up noticeable and comparable amounts of heavy metals from the medium (0.12 and 0.13 mg Co, 0.48 and 0.44 mg Cu or 4.2 and 2.1 mg Zn per gram of dry biomass, respectively, at a metal concentration of 0.2 mM in the medium), their metabolic responses differ essentially. Whereas for strain Sp7 the FTIR measurements showed significant accumulation of polyhydroxyalkanoates as storage materials involved in stress endurance, strain Sp245 did not show any major changes in cellular composition. Nevertheless, EMS measurements showed rapid binding of cobalt(II) by live bacterial cells (chemically similar to metal binding by dead bacteria) and its further transformation in the live cells within an hour.</p

Design, Synthesis and Pharmacological Evaluation of Novel C2,C3-Quinoxaline Derivatives as Promising Anxiolytic Agents

A new series of quinoxaline derivatives, 2a&ndash;4b, were synthesized and their anxiolytic potential was evaluated in vivo using elevated plus maze (EPM), open field (OF) and light-dark box (LDB) techniques. According to the results of the EPM, four active compounds were found in 2a, 2b, 2c, 4b. Their anxiolytic properties were confirmed in terms of LDB and the most active was compound 2b. In the OF, only 2c had an influence on the locomotor activity of the rodents. Thus, the most promising substance was determined; this was 2b, which has the structure of 2-(2-{[3-(4-tert-butylphenyl)quinoxaline-2-yl]methyl}-4,5-dimethoxyphenyl)-N-methylethan-1-amine hydrochloride. The obtained data were analyzed with the pharmacophore feature prediction approach, which made it possible to compare the structures of the studied compounds with the reference drug diazepam, and to determine the contribution of pharmacophores to the manifestation of the activity under study. ADMET analysis was carried out for compound 2b and the acute oral toxicity of this substance was also tested in vivo. As a result of the study, a promising compound with a high anxiolytic effect and low level of toxicity 2b was found, which is of interest for further preclinical study of its properties
