correlation of aerosol deposition before and after metered-dose inhaler coaching in healthy children.

Although pressurized metered dose inhaler (pMDI) education is a routine part of childhood asthma management and encouraging 'optimal breathing patterns' (i.e. slowly, deeply, completely, and with a mouth seal on the mouthpiece) is an integral part of recommended pMDI education, there is currently no quantifiable way to determine if a child is inhaling their medication correctly or optimally through a valved holding chamber (VHC).

Breath-Synchronized Nebulized Surfactant in a Porcine Model of Acute Respiratory Distress Syndrome.

Objectives: Effective treatment options for surfactant therapy in acute respiratory distress syndrome and coronavirus disease 2019 have not been established. To conduct preclinical studies in vitro and in vivo to evaluate efficiency, particle size, dosing, safety, and efficacy of inhaled surfactant using a breath-synchronized, nebulized delivery system in an established acute respiratory distress syndrome model.

Design: Preclinical study.

Physiologic Effects of Nasal Aspiration and Nasopharyngeal Suctioning on Infants With Viral Bronchiolitis.

Background: There is limited evidence supporting an optimum method for removing mucus from the airways of hospitalized infants with bronchiolitis. This study was designed to evaluate short-term physiologic effects between nasal aspiration and nasopharyngeal suctioning in infants.

Methods: Sixteen infants requiring hospitalization for supportive management of bronchiolitis were instrumented with transcutaneously measured partial pressure of carbon dioxide ([Formula: see text]) and [Formula: see text] monitoring.

Neonatal Jaundice: Improved Quality and Cost Savings After Implementation of a Standard Pathway.

Objectives: Seattle Children's Hospital sought to optimize the value equation for neonatal jaundice patients by creating a standard care pathway.

Methods: An evidence-based pathway for management of neonatal jaundice was created. This included multidisciplinary team assembly, comprehensive literature review, creation of a treatment algorithm and computer order sets, formulation of goals and metrics, roll-out of an education program for end users, and ongoing pathway improvement.

SOD1G93A Mutant Mice Develop a Neuroinflammation-Independent Dendropathy in Excitatory Neuronal Subsets of the Olfactory Bulb and Retina.

Nonmotor neuron-related pathology is a feature of amyotrophic lateral sclerosis (ALS), both in patients and in animal models. There is emerging evidence that sensory systems (olfaction and vision) are affected in humans. Here, we asked whether such sensory neuropathology is recapitulated in the superoxide dismutase 1 (SOD1G93A) mouse model of ALS.
