Трансплантация сердца от доноров, перенесших сердечно-легочную реанимацию

Heart transplantation from сardюpulmonary resuscitated (CPR) donors is one of the way to increase the availability of heart transplantation (HT). The study included 28 recipients: 25 (89,3%) men and 3 (10,7%) women at the age 20-68 (46,2 ± 13,7) who underwent HT from CPR donors in the V.I. Shumakov National Medical Research Center of Transplantology and Artificial Organs in the period from 01.01.2011 to 31.12.2017, that was 4.0% of the total number of HT (n = 698). CPR donor group and control group had no significantly differences in early cardiac transplant dysfunction and 1-, 3- and 5-year survival.Трансплантация сердца от доноров, перенесших сердечно-легочную реанимацию (СЛР) в процессе кондиционирования, является одним из вариантов увеличения доступности трансплантации сердца (ТС). В исследование включили 28 реципиентов: 25 (89,3%) мужчин и 3 (10,7%) женщины, возраст от 20 до 68 (46,2 ± 13,7) лет, которым в ФГУ «ФНЦТиИО им. академика В.И. Шумакова» в период с 01.01.2011 г. по 31.12.2017 г. была выполнена ТС от доноров, перенесших СЛР, что составило 4,0% от общего числа ТС за анализируемый период (n = 698). По частоте развития ранней дисфункции сердечного трансплантата, потребовавшей применения посттрансплантационной МПК, реципиенты групп «донор с СЛР» и «донор без СЛР» достоверно не различались. При сравнительном анализе достоверного различия в одно-, трехи пятилетней выживаемости реципиентов групп «донор с СЛР» и «донор без СЛР» выявлено не было

Branch Retinal Vein Occlusion: Pathogenesis, Visual Prognosis, and Treatment Modalities

In branch retinal vein occlusion (BRVO), abnormal arteriovenous crossing with vein compression, degenerative changes of the vessel wall and abnormal hematological factors constitute the primary mechanism of vessel occlusion. In general, BRVO has a good prognosis: 50–60% of eyes are reported to have a final visual acuity (VA) of 20/40 or better even without treatment. One important prognostic factor for final VA appears to be the initial VA. Grid laser photocoagulation is an established treatment for macular edema in a particular group of patients with BRVO, while promising results for this condition are shown by intravitreal application of steroids or new vascular endothelial growth factor inhibitors. Vitrectomy with or without arteriovenous sheathotomy combined with removal of the internal limiting membrane may improve vision in eyes with macular edema which are unresponsive to or ineligible for laser treatment

Rainbow factors in hypergraphs

For any $r$-graph $H$, we consider the problem of finding a rainbow $H$-factor in an $r$-graph $G$ with large minimum $\ell$-degree and an edge-colouring that is suitably bounded. We show that the asymptotic degree threshold is the same as that for finding an $H$-factor

Squaring the circle: an algorithm for generating polyhedral invariant sets from ellipsoidal ones

This paper presents a new (geometrical) approach to the computation of polyhedral (robustly) positively invariant (PI) sets for general (possibly discontinuous) nonlinear discrete-time systems possibly affected by disturbances. Given a β-contractive ellipsoidal set View the MathML source, the key idea is to construct a polyhedral set that lies between the ellipsoidal sets View the MathML source and View the MathML source. A proof that the resulting polyhedral set is contractive and thus, PI, is given, and a new algorithm is developed to construct the desired polyhedral set. The problem of computing polyhedral invariant sets is formulated as a number of quadratic programming (QP) problems. The number of QP problems is guaranteed to be finite and therefore, the algorithm has finite termination. An important application of the proposed algorithm is the computation of polyhedral terminal constraint sets for model predictive control based on quadratic costs
