When The Right Ventricle Fails After Left Ventricular Assist Device Implantation: Prediction Tools, Recognition Strategies, And Support Options, Juan Jose Rodriguez Arias, James Schurr, Phyllis Billia, Joyce W. Wald

Journal of Shock and Hemodynamics

The incidence of right heart failure (RHF) during durable left ventricular assist device (LVAD) surgery ranges from 9% to 42%, depending on the definition. RHF can be divided into three peri-implantation categories: early acute, early, and late. Despite many available risk models, predicting RHF before durable LVAD implantation has been difficult. Preemptive right-sided temporary mechanical circulatory support can improve outcomes; however, if intraoperative RHF is not suspected, early recognition and appropriate intervention after surgery are important.

All Decisions

In a holdover proceeding, the landlord sought possession, arguing the apartment was deregulated in 2005. The tenant counterclaimed for rent overcharges, alleging fraudulent deregulation due to a lack of renovations. The trial court granted possession to the landlord and dismissed the tenant's counterclaim. The Appellate Term affirmed, holding the landlord met its burden to prove lawful deregulation via vacancy and longevity increases, which pushed the rent over the threshold. The tenant failed to demonstrate fraud or overcharge. The court also found the tenant waived arguments regarding notice by not raising them below.

Vocal Stereotypy Interventions Using Response Interruption And Redirection, Haley Tallent

Electronic Theses & Dissertations

Vocal stereotypy is the repetitive, nonfunctional, and/or noncontextual vocalizations that are specifically maintained through internal reinforcement (Shawler, et al., 2020). Vocal stereotypy is commonly displayed in individuals with autism spectrum disorder (ASD); however, it may also occur in individuals with or without disabilities. When individuals engage in vocal stereotypy, they may lose learning opportunities, struggle to engage in daily tasks, and may even become stigmatized by their peers. One intervention used to reduce the frequency of vocal stereotypy in individuals with ASD is Response Interruption and Redirection (RIRD). RIRD was first evaluated for effectiveness in 2007 by Ahearn and colleagues. …
