Thermal deformation of concentrators in an axisymmetric temperature field

Axisymmetric thermal deformations of paraboloid mirrors, due to heating, are examined for a mirror with a optical axis oriented toward the Sun. A governing differential equation is derived using Mushtari-Donnel-Vlasov simplifications, and a solution is presented which makes it possible to determine the principal deformation characteristics

Dependent coordinates in path integral measure factorization

The transformation of the path integral measure under the reduction procedure in the dynamical systems with a symmetry is considered. The investigation is carried out in the case of the Wiener--type path integrals that are used for description of the diffusion on a smooth compact Riemannian manifold with the given free isometric action of the compact semisimple unimodular Lie group. The transformation of the path integral, which factorizes the path integral measure, is based on the application of the optimal nonlinear filtering equation from the stochastic theory. The integral relation between the kernels of the original and reduced semigroup are obtained.Comment: LaTeX2e, 28 page

Systemic vasculitides: сlinical cases

Systemic vasculitides (SV) are a group of diseases characterized by vessel wall inflammation that leads to ischemic changes in the organs and tissues, which the respective vessels supply blood to; the spectrum of the clinical manifestations of SV depends on the type, size, location of the affected vessels, and on the activity of systemic inflammation. The etiology of the majority of primary vasculitides is unknown. It is assumed that many microorganisms may initiate inflammation of vessels of various sizes, but only some forms of SV (and in some patients) can be clearly related to certain causative and/or trigger factors (drug hypersensitivity, hepatitis B virus, hepatitis C virus, etc.). The paper gives clinical examples of the timely diagnosis and treatment of 2 SV cases in young men working on the railway of the town of Ruzaevka

Опыт применения чрескожного обхода правого желудочка в раннем периоде после имплантации системы левожелудочкового обхода (клиническое наблюдение и обзор литературы)

Implantable left ventricular assist device (LVAD) is a state-of-the-art treatment for adults and children with end-stage heart failure. The early and late period after LVAD implantation can be severely complicated. Right ventricular failure (RVF) still remains a common complication after LVAD implantation. RVF is the cause of reduced post-implant survival. We suggest that an additional temporary or permanent right ventricular assist device (RVAD) is an effective treatment for LVAD-associated RVF. In this clinical case report, we describe the medical history of a pediatric patient (14 years old) with severe heart failure (PediMACS Level 1) against a background of dilated cardiomyopathy. The patient required peripheral venoarterial extracorporeal membrane oxygenation (VA-ECMO) prior to urgent LVAD (HM3) implantation. In the early post-LVAD implantation (1 POD) period, the patient presented with hemodynamic and echocardiographic events of acute RVF that was resistant to drug therapy (inotropic/vasopressor support, iNO) and required mechanical circulatory support (MCS) with a preoperatively implanted VA-ECMO. In the LVAD-associated RVF scenario, VA-ECMO as a means of total cardiac bypass is a non-physiological MCS method and, therefore, undesirable. In this clinical situation, our solution was to use a paracorporeal centrifugal blood pump for temporary right heart support. A RVAD was assembled using percutaneous cannulation in two sites and a modification of the pre-existing VA-ECMO circuit. For RVAD, we used an ECMO cannula previously installed through the femoral vein (26 F) and added a reverse venous cannula (22 F) through the right internal jugular vein into the pulmonary trunk. To facilitate the passage of the return cannula into the pulmonary artery, we used a contralateral sheath (6 F, 40 cm) and an Amplatz Super Stiff guidewire under radiological control. The oxygenator was removed from the circuit on day 2 of RVAD. Central hemodynamics (reduction in right atrial pressure (RAP) to 10 mm Hg, increase in pulmonary capillary wedge pressure (PCWP) to 14 mm Hg), as well as right ventricular (RV) and left ventricular (LV) volume characteristics all improved. These observations allowed us to optimize the performance of the implantable LVAD (increase in flow rate to 4.2 l/min or 2.1 l/min/m2). The duration of paracorporeal RVAD after LVAD implantation was 7 days with an average flow rate of 2.3 ± 0.2 l/min. Postoperative treatment in the intensive care unit (ICU) lasted for 15 days. The patient was discharged from the hospital on postoperative day 34.Система имплантируемого левожелудочкового обхода (LVAD) - это современный метод лечения взрослых и детей с сердечной недостаточностью в терминальной стадии. Ранние и поздние периоды после имплантации LVAD могут серьезно осложняться. Дисфункция правого желудочка (Д11Ж) по-прежнему остается одним из самых частых осложнений у пациентов с LVAD и причиной низкой постимплантационной выживаемости. Мы предполагаем, что дополнительное временное или постоянное вспомогательное устройство для правого желудочка (RVAD) является эффективным методом лечения LVAD-ассоциированного ДПЖ. В данном клиническом случае мы описываем историю болезни педиатрического пациента (14 лет) с тяжелой сердечной недостаточностью (Pedimacs Level 1) на фоне дилатационной кардиомиопатии, которому потребовалась периферическая ВА ЭКМО перед срочной имплантацией LVAD (HM3). В раннем постимплантационном (1 POD) периоде LVAD у этого пациента наблюдались гемодинамические и эхокардиографические явления остро развившейся ДПЖ, резистентной к медикаментозной терапии (инотропная/ вазопрессорная поддержка, iNO) и потребовавшей механической поддержки кровообращения с помощью предоперационно имплантированного ВА ЭКМО. В сценарии LVAD-ассоциированной ДПЖ ВА ЭКМО как средство полного шунтирования сердца является нефизиологическим методом МПК, и следовательно, нежелательным. В этой клинической ситуации нашим решением было использование паракорпорального центробежного насоса для временной поддержки правых отделов сердца. Вспомогательное устройство для правого желудочка (RVAD) было собрано с использованием метода чрескожной канюляции в двух местах и модификации ранее существовавшего контура ВА ЭКМО. Для RVAD мы использовали канюлю ЭКМО, установленную ранее через бедренную вену (26 F), и добавили возвратную венозную канюлю (22 F) через правую внутреннюю яремную вену в ствол легочной артерии. Для облегчения прохождения возвратной канюли в легочную артерию мы использовали контралатеральный интродьюсер (6 F, 40 см) и проводник типа Amplatz Super Stiff под рентгенологическим контролем. Оксигенатор был удален из контура на вторые сутки RVAD. На фоне ПЖО мы отметили улучшение показателей центральной гемодинамики (снижение ДПП до 10 мм рт. ст., увеличение ЗДЛА до 14 мм рт. ст.) и объемных характеристик ПЖ и ЛЖ, что позволило оптимизировать функционирование иЛЖО (увеличение производительности до 4,2 л/мин, или 2,1 л/ мин/м2). Продолжительность паракорпорального ПЖО после имплантации ЛЖО составила 7 суток при усредненной производительности 2,3 ± 0,2 л/мин. Период послеоперационного лечения в условиях ОРИТ составил 15 суток. Пациент выписан из стационара на 34-е послеоперационные сутки
