Severe Aortic Stenosis in Dialysis Patients

Background: Characteristics and prognosis of hemodialysis patients with severe aortic stenosis have not yet been well defined. Methods and Results: The CURRENT AS (contemporary outcomes after surgery and medical treatment in patients with severe aortic stenosis) registry, a Japanese multicenter registry, enrolled 3815 consecutive patients with severe aortic stenosis. There were 405 hemodialysis patients (initial aortic valve replacement [AVR] group: N=135 [33.3%], and conservative group: N=270) and 3410 nonhemodialysis patients (initial AVR group: N=1062 [31.1%], and conservative group: N=2348). The median follow‐up duration after the index echocardiography was 1361 days, with 90% follow‐up rate at 2 years. The cumulative 5‐year incidence of all‐cause death was significantly higher in hemodialysis patients than in nonhemodialysis patients in both the entire cohort (71% versus 40%, P<0.001) and in the initial AVR group (63.2% versus 17.9%, P<0.001). Among hemodialysis patients, the initial AVR group as compared with the conservative group was associated with significantly lower cumulative 5‐year incidences of all‐cause death (60.6% versus 75.5%, P<0.001) and sudden death (10.2% versus 31.7%, P<0.001). Nevertheless, the rate of aortic valve procedure–related death, which predominantly occurred within 6 months of the AVR procedure, was markedly higher in the hemodialysis patients than in the nonhemodialysis patients (21.2% and 2.3%, P<0.001). Conclusions: Among hemodialysis patients with severe aortic stenosis, the initial AVR strategy as compared with the conservative strategy was associated with significantly lower long‐term mortality risk, particularly the risk for sudden death, although the effect size for the survival benefit of the initial AVR strategy was smaller than that in the nonhemodialysis patients

Anti-inflammatory roles of interleukin-35 in the pathogenesis of Japanese cedar pollinosis.

Background:Interleukin (IL)-35 has been recently identified as an anti-inflammatory cytokine in allergic inflammation. However, its biological role in the pathogenesis of allergic rhinitis has not been fully elucidated.Objective:The purpose of this study was to investigate the anti-inflammatory activity of IL-35 in the pathogenesis of allergic rhinitis in patients with Japanese cedar pollinosis (JCP).Methods:Peripheral blood mononuclear cells were collected from healthy controls and JCP patients during the off-season for pollen. Peripheral blood mononuclear cells were incubated with Cry j 1, a major allergen of Japanese cedar pollen and production of IL-5, IL-13, and IL-35 were measured by enzyme-linked immunosorbent assay. Th2 (CD4+ST2+) cells and group 2 innate lymphoid cells were isolated from peripheral blood mononuclear cells of JCP patients, and the inhibitory effects of IL-35 on cell differentiation, proliferation and mRNA expression of IL-5, IL-13, and GATA3 were examined. B cells were also isolated and the effects of IL-35 on total IgE production were examined.Results:Cry j 1-induced production of IL-5 and IL-13 was significantly increased in peripheral blood mononuclear cells from JCP patients, whereas Cry j 1-induced IL-35 production was significantly decreased compared with healthy controls. IL-35 significantly inhibited Th2 cell differentiation, group 2 innate lymphoid cell proliferation, and mRNA expression of IL-5, IL-13, and GATA3 in Th2 cells and group 2 innate lymphoid cells. IL-35 also inhibited IgE production from B cells.Conclusion:IL-35 is an important anti-inflammatory cytokine in JCP, and its biological roles include the downregulation of Th2 cells and group 2 innate lymphoid cells, and the inhibition of IgE production from B cells. These findings demonstrate that IL-35 may have the potential to exert anti-allergic effects for the treatment of allergic rhinitis

Topology Optimization of Electromagnetic Devices Using Digital Annealer

Topology optimization (TO) has been formulated as a quadratic unconstrained binary optimization (QUBO) problem that can be solved by Digital Annealer (DA) and quantum computers, which can realize massive parallelization. It is shown that the 3-D TO of a permanent magnet (PM), with 600 unknowns, is successfully performed by the DA with the aid of the finite element method (FEM) for field computations. Moreover, it is shown to perform TO of a magnetic core, with 758 unknowns, in such a way that the QUBO and field problems are iteratively solved to determine the optimal solution in which the magnetic field and optimal core structure are self-consistent
