Tinnitus is associated with increased extracellular matrix density in the auditory cortex of Mongolian gerbils.

Most scientists agree that subjective tinnitus is the pathological result of an interaction of damage to the peripheral auditory system and central neuroplastic adaptations. Here we investigate such tinnitus related adaptations in the primary auditory cortex (AC) 7 and 13 days after noise trauma induction of tinnitus by quantifying the density of the extracellular matrix (ECM) in the AC of Mongolian gerbils (Meriones unguiculatus). The ECM density has been shown to be relevant for neuroplastic processes and synaptic stability within the cortex.

Depression and Implantable Cardioverter-Defibrillator Implantation in Black Patients at Risk for Sudden Cardiac Death.

Background: Black patients meeting indications for implantable cardioverter-defibrillators (ICDs) have lower rates of implantation compared with White patients. There is little understanding of how mental health impacts the decision-making process among Black patients considering ICDs. Our objective was to assess the association between depressive symptoms and ICD implantation among Black patients with heart failure.

Fluid Management in Veno-Arterial Extracorporeal Membrane Oxygenation Therapy-Analysis of an Experimental Pig Model.

(1) Background: Fluid resuscitation is a necessary part of therapeutic measures to maintain sufficient hemodynamics in extracorporeal membrane oxygenation (ECMO) circulation. In a post-hoc analysis, we aimed to investigate the impact of increased volume therapy in veno-arterial ECMO circulation on renal function and organ edema in a large animal model. (2) Methods: ECMO therapy was performed in 12 female pigs (Deutsche Landrasse × Pietrain) for 10 h with subsequent euthanasia.
