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...

Non-small cell lung cancer (NSCLC) initiates in the non-small cells of the lung and is one of the most common types of human cancer. It is known for its rapid growth, easy migration, invasion and reoccurrence, and has the highest incidence rate of all types of cancer. Early detection of NSCLC is difficult to achieve and this is the primary reason for low survival rates in NSCLC. Contrast-enhanced ultrasound is the most common application for evaluating patients diagnosed with NSCLC. In the present study, a contrast-enhanced ultrasound combined with nanoparticles was performed with the aim of identifying patients with NSCLC at an early stage...

Background: Inhaled tobramycin is important in the treatment of Pseudomonas aeruginosa ( Pa ) infections in cystic fibrosis (CF). However, despite its use it fails to attenuate the clinical progression of CF lung disease. The bactericidal efficacy of tobramycin is known to be concentration-dependent and hence changing the dosing regimen from a twice-daily (q12h) inhalation to a once-daily (q24h) inhaled double dose could improve treatment outcomes. Objectives: To predict local concentrations of nebulized tobramycin in the airways of patients with CF, delivered with the small airway-targeting Akita ® system or standard PARI-LC ® Plus system, with different inspiratory flow profiles...

: Chronic obstructive pulmonary disease (COPD) is a prevalent and disabling disorder in the United States, especially affecting older individuals, women, and those with a history of smoking. Studies show that COPD may be underrepresented, underdiagnosed, and undertreated in elderly patients residing in long-term care (LTC) facilities. The quality of care for LTC residents with COPD is heterogeneous in regard to both the facility and the patient. For LTC facilities, care should be driven by staff education, interstaff communication, and interfacility communication...
