Control system of a high-power infrared free electron laser

The control system of the high power infrared FEL is built on the base of a two-level distributed system. The system includes the operator interface at the upper level and Input/Output Controllers under supervision of the real time operating system at the lower level. All hardware for the control system of the FEL is produced by our institute, which solves several problems of hard real time and reduces cost of equipment

First experimental results obtained using the highpower free electron laser at the siberian center for photochemical research

The first lasing near the wavelength of 140 µm was achieved in April 2003 using a high-power free electron laser (FEL) constructed at the Siberian Center for Photochemical Research. In this paper we briefly describe the design of the FEL driven by an accelerator–recuperator. Characteristics of the electron beam and terahertz laser radiation, obtained in the first experiments, are also presented in the paper.У Сибірському центрі фотохімічних досліджень навесні 2003 року отримана генерація випромінювання з довжиною хвилі 140 мкм на потужному лазері на вільних електронах (ЛВЕ).

On the effectiveness of inpatient treatment of children with comorbid pathology [К вопросу об эффективности стационарного лечения детей с сочетанной патологией]

Introduction. A comprehensive approach in providing of medical aid to a child with comorbid pathology is intended to mean that child receives high-quality diagnostics, treatment, rehabilitation and informational support in the full extent in regard to all the diseases child has. The main problems of this category of patients are need of expanding treatment and diagnostic activities, attracting of consultants and also increasing of resource costs and breakdown of response to treatment. The goal of research is to study the efficiency of hospital treatment of children with comorbidities in complex examination and treatment. Material and methods. It was examined 616 children aged 7–14 years, hospitalized for asthma. At the same time, 368 children had comorbidities. One half of patients with comorbid pathology received a comprehensive examination and taking into account comorbidities, the other half – a standard set of examination and treatment of the main disease. The survey of parents and catamnestic observation of patients for 1 year was carried out. Results. The presence of comorbidities in children with bronchial asthma, in particular the obesity and gastroenterological diseases, has a significant negative impact on the course of asthma, the efficiency of its therapy and the need for medical aid. The results of the study showed that children with high levels of comorbidity have more frequent and prolonged hospitalizations. Comprehensive screening and early treatment of comorbidities reduces the incidence of exacerbations, the risk of emergency hospitalizations and improves asthma control. Discussion. An increase in the duration of hospitalization of patients with comorbid pathology may be associated with a severity of the main illness and a lower rate of response to therapy, possibly with reduced compliance. Although the presence of comorbidities contributes to the lengthening of hospitalization, a comprehensive examination and treatment does not increase the duration of the child’s stay in the hospital. Conclision. The expansion of diagnostic and therapeutic actions in relation to concomitant diseases in a patient with bronchial asthma within the framework of hospitalization increases the clinical and economic efficiency of treatment measures, reduces the subsequent burden on the hospital and out-patient hospital, increases the assessment of medical care by parents and their adherence to the prescribed treatment. © КОЛЛЕКТИВ АВТОРОВ, 202

К ВОПРОСУ ОБ ЭФФЕКТИВНОСТИ СТАЦИОНАРНОГО ЛЕЧЕНИЯ ДЕТЕЙ С СОЧЕТАННОЙ ПАТОЛОГИЕЙ

Комплексный подход при оказании медицинской помощи детям с сочетанной патологией подразумевает получение ими качественной диагностики, лечения, реабилитации и информационной поддержки в полном объёме в отношении всех имеющихся у них заболеваний. Основные проблемы данной категории пациентов - необходимость расширения лечебно-диагностических действий и привлечения консультантов, повышение затрат ресурсов и ухудшение прогноза лечения. Цель: изучить эффективность стационарного лечения детей с сопутствующей патологией при комплексном обследовании и лечении. Материал и методы. Обследовано 616 детей в возрасте 7-14 лет, госпитализированных по поводу бронхиальной астмы. При этом 368 детей имели сопутствующую патологию. Половина пациентов с сочетанной патологией получала комплексное обследование и рекомендации, учитывающие сопутствующие заболевания, другая часть - стандартный набор обследования и лечения основного заболевания. Проведено анкетирование родителей и катамнестическое наблюдение пациентов в течение 1 года. Результаты. Наличие сопутствующей патологии у детей с бронхиальной астмой, в частности ожирения и гастроэнтерологических заболеваний, оказывает существенное негативное влияние на течение астмы, эффективность её терапии и потребность в медицинской помощи. Результаты исследования показали, что дети с высоким уровнем коморбидности имеют более частые и продолжительные госпитализации. Проведение комплексного обследования и раннее начало лечения сопутствующих заболеваний снижает частоту обострений, риск экстренных госпитализаций и улучшает контроль над астмой. Обсуждение. Увеличение длительности госпитализации пациентов с сочетанной патологией может быть связано с большей тяжестью основного заболевания и меньшей скоростью ответа на терапию, возможно со сниженной комплаентностью. Хотя наличие сопутствующей патологии способствует удлинению сроков госпитализации, проведение комплексного обследования и лечения не увеличивает срок пребывания ребёнка в стационаре. Заключение. Расширение диагностических и лечебных действий в отношении имеющихся у больного бронхиальной астмой сопутствующих заболеваний в рамках госпитализации повышает клиническую и экономическую эффективность лечебных мероприятий, уменьшает последующую нагрузку на стационар и поликлинику, повышает оценку медицинской помощи со стороны родителей и их приверженность назначенному лечению

Intracavity Thermometry in Medicine

We present here an analytical review of technical means used for intracavity thermometry of biological objects. Radiometers can be effective both in medicine and veterinary medicine. The opportunities for determining the 3D distribution and dynamics of brightness temperatures measured though natural cavities in the human body are discussed. © 2021, Springer Science+Business Media, LLC, part of Springer Nature

FACTORS DETERMINING THE HOSPITALISATION DURATION OF STAY IN CHILDREN WITH SEVERE RESPIRATORY SYNCYTIAL VIRUS (RSV) INFECTION IN THE RUSSIAN FEDERATION

The epidemiologic data on RSV infection prevalence in the Russian Federation and its impact on respiratory morbidity in the pediatric population are limited. This article provides the analysis of results of a prospective, multicenter, observational cohort study. The study was conducted in 9 centers in the Russian Federation — in Moscow, St. Petersburg, and Tomsk. Children less than 2 years of age were included. It was found that during the season of high RSV morbidity RSV is found in 38 % of children hospitalized for lower respiratory tract infections; mean hospitalisation duration in children with severe RSV infection was over 1 week. Usually the duration of hospitalization was associated with disease severity and requirements for healthcare resources and oxygen supplementation. Moreover, in the Russian Federation the hospital length of stay in patients with RSV infection depended on the type of medical insurance. It was demonstrated that RSV infection caused severe respiratory failure in some infants less than 1 year of age and, therefore, was a substantial burden for the system of hospital medical care in the Russian Federation. Prophylaxis of severe RSV infection in high-risk groups of children during the might reduce the need for hospitalization. Key words: respiratory syncytial virus infection, bronchiolitis, risk factors, prophylaxis, epidemiology, children. (Pediatric pharmacology. — 2011; 8 (6): 61–66)
