BACKGROUND: Holding chambers or spacers can enhance the efficacy of pressurized metered dose inhalers (pMDI) in delivering inhaled medications, as they reduce the need for hand-breath coordination and improve lower airways deposition. Nevertheless, their cost can be high for patients in low-income countries. OBJECTIVE: To compare asthma control achieved with beclomethasone-dipropionate administered through a hydrofluoroalkane-driven pMDI (BDp-pMDI) coupled to a home-made spacer (HmS) or to a valved commercial spacer (VCS) as auxiliary devices...

Ahmed O Shalash, Mustafa M A Elsayed
The potential of fine excipient materials to improve the performance of carrier-based dry powder inhalation mixtures is well acknowledged. The mechanisms underlying this potential are, however, open to question till date. Elaborate understanding of these mechanisms is a requisite for rational rather than empirical development of ternary dry powder inhalation mixtures. While effects of fine excipient materials on drug adhesion to and detachment from surfaces of carrier particle have been extensively investigated, effects on other processes, such as carrier-drug mixing, capsule/blister/device filling, or aerosolization in inhaler devices, have received little attention...

Tobramycin Inhalation Powder (TIP) is a spray-dried engineered particle formulation used in TOBI® Podhaler®, a drug/device combination for treatment of cystic fibrosis. A TIP particle consists of two phases: amorphous, glassy tobramycin sulfate and a gel-phase phospholipid (DSPC). The objective of this work was to characterize both the amorphous and gel phases following exposure of TIP to a broad range of relative humidity and temperature. Because, in principle, changes in either particle morphology or the solid-state form of the drug could affect drug delivery or biopharmaceutical properties, understanding physical stability was critical to development and registration of this product...

Background: Nano-specific inhalation exposure models could potentially be effective tools to assess and control worker exposure to nano-objects, and their aggregates and agglomerates (NOAA). However, due to the lack of reliable and consistent collected NOAA exposure data, the scientific basis for validation of the existing NOAA exposure models is missing or limited. The main objective of this study was to gain more insight into the effect of various determinants underlying the potential on the concentration of airborne NOAA close to the source with the purpose of providing a scientific basis for existing and future exposure inhalation models...

BACKGROUND: Patients receiving noninvasive ventilation (NIV) may benefit from medical aerosol, but most guidance on dosing with different aerosol devices is limited to in-vitro studies. The study was designed to in-vitro, ex-vivo, and in-vivo compare aerosol delivery during bilevel NIV with three types of aerosol generators: metered dose inhaler with AeroChamber-MV spacer (AC), Aerogen Pro vibrating mesh nebulizer (PRO), and Sidestream jet nebulizer (SIDE). MATERIALS AND METHOD: A bilevel ventilator with dry single limb circuit and fixed expiratory port was set in spontaneous mode with initial inspiratory and expiratory pressures of 20 and 5 cmH20, 1:3 inspiratory-expiratory ratio, and 15 breaths...

Aerosol drugs are effectively used to treat chronic respiratory diseases. The efficiency of the therapy depends also on the amount and distribution of drug deposited within the airways. The objective of this study is to apply numerical techniques to analyse the effect of the duration of breath-hold after the inhalation of six different commercialized dry powder drugs on their lung deposition. For this purpose a computational airway deposition model has been adapted and validated to the special case of therapeutic aerosols...

OBJECTIVES: Although right ventricular failure (RVF) is a major concern after left ventricular assist device (LVAD) implantation, methodologies to evaluate RV function remain limited. Liver stiffness (LS), which is closely related to right-sided filling pressure and may indicate RVF severity, could be non-invasively and repeatedly assessed using transient elastography. Here we investigated the suitability of LS as a parameter of RV function in pre- and post-LVAD periods. METHODS: The study included 55 patients with LVAD implantation as a bridge to transplantation between 2011 and 2015 whose LS was assessed using transient elastography...

Inhaler device errors are common and may impact the effectiveness of the delivered drug. There is a paucity of up-to-date systematic reviews (SRs) or meta-analyses (MAs) of device errors in asthma and chronic obstructive pulmonary disease (COPD) patients. This SR and MA provides an estimate of overall error rates (both critical and non-critical) by device type and evaluates factors associated with inhaler misuse. The following databases from inception to July 23, 2014 (Embase®, MEDLINE®, MEDLINE® In-Process and CENTRAL) were searched, using predefined search terms...

Chemical fate is a concern at environmentally contaminated sites, but characterizing that fate can be difficult. Identifying and quantifying the movement of chemicals at the air-water interface are important steps in characterizing chemical fate. Superfund sites are often suspected sources of air pollution due to legacy sediment and water contamination. A quantitative assessment of polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAH (OPAHs) diffusive flux in a river system that contains a Superfund Mega-site, and passes through residential, urban and agricultural land, has not been reported before...

Despite the fact that inhaled medications have been the basis for treating patients with respiratory diseases for more than 60 years, we are repeatedly reminded that many individuals cannot use their inhaler devices correctly ( Capstick and Clifton 2012 , Scullion and Holmes 2013 , Sanchis et al 2016 ).This is often because healthcare professionals cannot use the devices correctly either and they teach less than optimum techniques to patients. This in turn results in poor control and, potentially, death.

OBJECTIVE: Cannabis use has increased in the United States, particularly the use of vaporized cannabis oil, which is often mixed with thinning agents for use in vaporizing devices. E-cigarette research shows that heated thinning agents produce potentially harmful carbonyls; however, similar studies have not been conducted (1) with agents that are commonly used in the cannabis industry and (2) at temperatures that are appropriate for cannabis oil vaporization. The goal of this study was to determine whether thinning agents used in the cannabis industry produce potentially harmful carbonyls when heated to a temperature that is appropriate for cannabis oil vaporization...

INTRODUCTION: PET imaging with (11)C-nicotine-loaded cigarettes is a valuable tool to directly assess fast nicotine kinetics and its neuropharmacological role in tobacco dependence. To eliminate variations among puffs inhaled by subjects, this work aimed to develop a programmable smoke delivery device (SDD) to produce highly reproducible and adjustable puffs of cigarette smoke for PET experiments. NEW METHOD: The SDD was built around a programmable syringe pump as a smoking machine to draw a puff of smoke from a (11)C-nicotine-loaded cigarette and make it available for a subject to take the smoke into the mouth and then inhale it during PET data acquisition...

Electronic cigarettes are increasingly popular as a supposed safer alternative to tobacco cigarettes or a smoking cessation tool. Research and debate have focused primarily on possible adverse effects caused by the inhaled aerosol produced by electronic cigarettes and on smoking cessation efficacy. Few reports in the medical literature describe injuries secondary to device malfunction. We present a case of electronic cigarette explosion, with a projectile fracturing the patient's right naso-orbital-ethmoid complex and anterior and posterior frontal sinus tables, with frontal sinus outflow tract involvement...
