RATIONALE: Every year, ∼40,000 people suffer burn-related injuries in the United States. Despite recent advances, the odds of dying from exposure to fire, flames, or smoke are one in ∼1500. Smoke inhalation causes injury to the airways via a complex physiological process, and the treatment is mainly supportive. Many recent interventions aim to decrease the formation of fibrin casts, the main cause of airway damage in these patients. Among these, treatment with a combination of nebulized heparin and N-acetylcysteine (NAC) has shown benefit...

BACKGROUND: Despite improvements in perinatal care, bronchopulmonary dysplasia (BPD) in extremely premature infants has not decreased. Postnatal surfactant therapy provides symptomatic relief from respiratory distress syndrome, but does not translate into a reduction in BPD. Therefore, the search for effective interventions to prevent BPD continues. OBJECTIVES: Since PPAR-γ agonists have been demonstrated to promote neonatal lung maturation and injury repair, we hypothesized that a formulation of a PPAR-γ agonist, pioglitazone (PGZ) and a synthetic lung surfactant (a surfactant protein B peptide mimic, B-YL) combined would stimulate lung maturation and block hyperoxia-induced neonatal lung injury more effectively than either modality alone...

INS1009 is a long acting pulmonary vasodilator prodrug of treprostinil (TRE) that is formulated in a lipid nanoparticle for inhaled delivery by nebulization. This study examined the ability of INS1009 to inhibit vasoconstriction in the pulmonary vasculature of rats and dogs and the extent to which local activity within the lung contributes to its activity. Rats received a single dose of INS1009 by nose-only inhalation or were given a continuous intravenous (i.v.) infusion of TRE, followed by an i.v. challenge of the thromboxane mimetic pulmonary vasoconstrictor U46619 and the increase in pulmonary arterial pressure (PAP) was measured...

OBJECTIVE: Previous in vitro and animal studies have suggested that osteopontin (OPN), an inflammatory extracellular matrix protein, is involved in the formation and growth of abdominal aortic aneurysms (AAAs). However, the mechanism by which this occurs continues to be nebulous. The relationship between OPN and inflammation-suppressing lymphocytes present in the human AAA condition was investigated and presented herein. METHODS: Serum OPN concentrations were measured in healthy, risk factor-matched non-AAA and AAA patients by enzyme-linked immunosorbent assay (ELISA)...

Hypertriglyceridemia is the third most common worldwide cause of acute pancreatitis. Resolving the underlying etiology is imperative for optimal management. This is especially true with regard to hypertriglyceridemia, as this etiology may cause more severe acute pancreatitis and worse symptoms than other causes of the disease. Many pharmacological treatment options for hypertriglyceridemia-induced acute pancreatitis (HTGP) have been proposed; however, the safety and efficacy for specific treatment regimens remain nebulous...

In this study, continuous in-source hydrogen/deuterium exchange (HDX) atmospheric pressure photoionization (APPI) mass spectrometry (MS) with continuous feeding of D2 O was developed and validated. D2 O was continuously fed using a capillary line placed on the center of a metal plate positioned between the UV lamp and nebulizer. The proposed system overcomes the limitations of previously reported APPI HDX-MS approaches where deuterated solvents were premixed with sample solutions before ionization. This is particularly important for APPI because solvent composition can greatly influence ionization efficiency as well as the solubility of analytes...

Nanoparticles (NPs) can be released in the air in work settings, but various factors influence the exposure of workers. Controlled inhalation experiments can thus be conducted in an attempt to reproduce real-life exposure conditions and assess inhalation toxicology. Methods exist to generate aerosols, but it remains difficult to obtain nano-sized and stable aerosols suitable for inhalation experiments. The goal of this work was to characterize aerosols of titanium dioxide (TiO₂) NPs, generated using a novel inhalation system equipped with three types of generators-a wet collision jet nebulizer, a dry dust jet and an electrospray aerosolizer-with the aim of producing stable aerosols with a nano-diameter average (<100 nm) and monodispersed distribution for future rodent exposures and toxicological studies...

To date, preterm infants with respiratory distress syndrome (RDS) after birth have been managed with a combination of endotracheal intubation, surfactant instillation, and mechanical ventilation. It is now recognized that noninvasive ventilation (NIV) such as nasal continuous positive airway pressure (CPAP) in preterm infants is a reasonable alternative to elective intubation after birth. Recently, a meta-analysis of large controlled trials comparing conventional methods and nasal CPAP suggested that CPAP decreased the risk of the combined outcome of bronchopulmonary dysplasia or death...

Iatrogenic pneumothorax refers to the pneumothorax generated after diagnostic or therapeutic procedure. We report the case of a 40-year-old male who had bilateral simultaneous iatrogenic pneumothorax with pneumomediastinum leading to cardiac arrest situation, due to wrong placement of nebulization kit in spontaneously breathing intubated patient. We report this case for its rarity, due to the critical importance of this cause as a etiology of bilateral simultaneous iatrogenic pneumothorax leading to cardiac arrest situation, and need to understand the importance of continuous training and stress of emergency environment...

Determination of fine droplet dose with preparations for nebulization, currently deemed to be the metric most indicative of lung deposition and thus in vivo responses, involves combining two procedures following practice as described in the United States Pharmacopeia and the European Pharmacopeia. Delivered dose (DD) is established by simulating tidal breathing at the nebulizer, collecting the medication on a filter downstream of the nebulizer mouthpiece/facemask. Fine droplet fraction (FDF<x μm ) is determined separately using a cooled cascade impactor operated at 15 L/min...

The delivery of aerosols to mechanically ventilated patients presents unique challenges and differs from inhaled drug delivery in spontaneously breathing patients in several respects. Successful aerosol delivery during invasive mechanical ventilation requires careful consideration of a host of factors that influence the amount of drug inhaled by the patient. Pressurized metered-dose inhalers and nebulizers (jet, ultrasonic, and vibrating mesh) are the most commonly used aerosol delivery devices in these patients, although other delivery devices, such as dry powder inhalers, soft mist inhalers, and intratracheal nebulizing catheters, could also be adapted for in-line use...
