With the emergence of transcatheter tricuspid valve repair technologies that mimic these conventional surgical techniques, we compared their mid-term outcomes and longitudinal echocardiographic profiles.MethodsFrom 2002 to 2016, 650 patients underwent TV repair (324 Ring and 326 Suture-bicuspidization) for primary or functional tricuspid regurgitation (TR). Concomitant aortic valve, mitral valve or CABG procedures were included but tricuspid valve replacement, concomitant aortic procedures, heart transplantation or ventricular assist device placement procedures were excluded. Tricuspid valve event-free survival was estimated using Kaplan-Meier competing risk analysis. Freedom from TR recurrence (defined as at least moderate TR) and freedom from tricuspid valve reoperation were also assessed.ResultsThere were no statistical differences in terms of age, gender, and most baseline comorbidities (P>0.05). In-hospital outcomes also did not significantly differ between the two groups (P>0.05). However, Suture-bicuspidization was associa...

MuetzelAbstractGyrification of the cerebral cortex changes with aging and relates to development of cognitive function during early life and midlife. Little is known about how gyrification relates to age and cognitive function later in life. We investigated this in 4,397 individuals (mean age: 63.5 years, range: 45.7 to 97.9) from the Rotterdam Study, a population-based cohort. Global and local gyrification were assessed from T1-weighted images. A measure for glob...

Publication date: Available online 17 February 2020Source: NeurocomputingAuthor(s): Cuili Yang, Xinxin Zhu, Junfei Qiao, Kaizhe NieAbstractAs extension of traditional echo state networks (ESNs), the polynomial echo state networks (PESNs) have been proposed in our previous work (C.L. Yang, J.F. Qiao, H.G. Han, L. Wang, Design of polynomial echo state networks for time series prediction, Neurocomputing 290 (2018) 148-160.) by employing the polynomial function of complete input variable as output weight matrix. In practice, the generalization performance and computational burden of PESNs are perturbed by redundant or irreleva...

Publication date: May 2020Source: Clinica Chimica Acta, Volume 504Author(s): Damian Jacenik, Jakub FichnaAbstractChemerin is a multifunctional protein involved among others in adipogenesis, angiogenesis and lipid as well as glucose metabolism. Chemerin is an essential factor in promotion of chemotaxis of numerous immune cell types and plays an important role in several pathophysiologic conditions. Chemerin receptors are present on monocytes/macrophages, T cells, natural killer and dendritic cells as well as neutrophils. However, the role of chemerin and chemerin receptors in immune response and gastrointestinal diseases is...

ConclusionsPatients with CMS were more likely to present with increased comorbidities. Patients with CMS undergoing CABG were at risk for worse short ‐term secondary postoperative outcomes and reduced long‐term survival. The data supports the need for further investigation for risk reduction surrounding operative revascularization.

AbstractThe first successful human heart transplantation was reported on 3 December 1967, by Christiaan Barnard in South Africa. Since then this life ‐saving procedure has been performed in over 120 000 patients. A limitation to the performance of this procedure is the availability of donor hearts with as many as 20% of patients dying before a donor's heart is available for transplant. Today, hearts for transplantation are procured from indiv iduals experiencing donation after brain death (DBD). Interestingly, this, however, was not always the case as the first heart transplants occurred after circulatory dea...

AbstractCoarctation is rare in patients over 50 years of age; however, if present, it can be associated with complex intracardiac pathologies and represent a formidable surgical challenge. Herein, we report a single ‐stage approach for surgical repair of coarctation associated with aortic, mitral, and tricuspid valve pathology using an ascending‐to‐descending aortic bypass with posterior pericardial access.

We describe the clinical outcomes of adults who received ECMO in septic shock.MethodsWe retrospectively studied adults supported on veno-arterial or veno-venous modes of ECMO with septic shock at the time of cannulation from 1/1/2009-12/31/2016 at a quaternary medical center in the United States. The primary outcome was rate of survival to hospital discharge and time to survival using Kaplan-Meier survival estimates. We analyzed survival by mode, previous cardiac arrest and timing of cannulation (
