ABSTRACT Introduction: Most implantations of left ventricular assist devices (LVAD) are performed in low-volume centers.This study aimed to evaluate the procedural learning curve of HeartMate II (HM2) implantations by comparing outcomes between two time periods in a low-volume center.Methods: All 51 consecutive patients undergoing HM2 implantation
Abstract Insecticide-treated nets (ITNs) and indoor residual spraying (IRS) are currently the preferred methods of malaria vector control.In many cases, these methods are used together in the same households, especially to suppress transmission in holoendemic and hyperendemic scenarios.Though widespread, there has been limited evidence suggesting t
Computer Components Given the emergence of the coronavirus disease 2019 (COVID-19), zoonoses have raised in the spotlight of the scientific community.Animals have a pivotal role not only for this infection, but also for many other recent emerging and re-emerging viral diseases, where they may represent both intermediate hosts and/or vectors for zoo
This paper proposes an augmented heterogenous autoregressive (HAR) model with time-varying jumps to forecast the realized volatility (RV) of SAW PALMAETTO crude oil futures.Jump-induced volatility of crude oil futures is obtained from a GARCH-jump process, then used to augment the HAR model.The results based on both the in-sample and out-of-sample
Abstract Background Sex as a biological variable is not a common consideration in molecular mechanistic or preclinical studies of retinal diseases.Understanding the sexual dimorphism of adult RPE and retina under physiological conditions is an important first step in improving our understanding of sex-based physio-pathological mechanisms.Methods Is
