Utilization of the lower inflection point of the pressure-volume curve results in protective conventional ventilation comparable to high frequency oscillatory ventilation in an animal model of acute respiratory distress syndrome

Clinics, 2008
INTRODUCTION: Studies comparing high frequency oscillatory and conventional ventilation in acute respiratory distress syndrome have used low values of positive end-expiratory pressure and identified a need for better recruitment and pulmonary stability ...

Nasal High Frequency Oscillatory Ventilation for Respiratory Failure due to Respiratory Syncytial Virus Bronchiolitis: Case Report

American Journal of Perinatology Reports, 2020
The authors describe a case of acute respiratory failure due to severe bronchiolitis. During high-flow nasal cannula ventilation, the blood's high levels of hypercapnia had taken them to plan the sedation and the orotracheal intubation.

Sub-cortical and brainstem sites associated with chemo-stimulated increases in ventilation in humans [PDF]

, 2010
We investigated the neural basis for spontaneous chemo-stimulated increases in ventilation in awake, healthy humans. Blood oxygen level dependent (BOLD) functional MRI was performed in nine healthy subjects using T2weighted echo planar imaging.

Race and Household Income are Associated with Disease Outcomes in Pediatric Patients with ANCA‐associated Vasculitis Hospitalized in the United States

Arthritis Care &Research, Accepted Article.
Objectives Race and household income impact outcomes in patients with rheumatic conditions; however, their role in pediatric anti‐neutrophil cytoplasmic antibody (ANCA)‐associated vasculitis (AAV) remains poorly understood. We aimed to evaluate whether race/ethnicity and household income are associated with severe AAV disease and renal outcomes among ...

Soft Neural Interfaces for Circuit‐Level Analysis of Magnetogenetic Deep Brain Stimulation in Parkinson's Disease Models

Advanced Healthcare Materials, EarlyView.
ABSTRACT Magnetogenetic deep brain stimulation (MG‐DBS) represents a wireless neuromodulation that has demonstrated long‐lasting behavioral benefits in Parkinson's disease models. However, the circuit‐level mechanisms underlying these therapeutic effects have remained uncharacterized due to limitations of conventional neural interfaces.
