background the relationship between gastroesophageal reflux (gerd) and airway diseases is still a matter of debate. oscillometry is an objective, independent tool for the evaluation of airway resistance. the main purpose of this study is to comparespirometry and oscillometry results before and after treatment by a proton pump inhibitor (ppi) in a group of gerd patients who have no respiratory s...

Peribronchial edema has been proposed as a mechanism enhancing airway responses to constrictor stimuli. Acute exposure to altitude in nonacclimatized lowlanders leads to subclinical interstitial pulmonary edema that lasts for several days after ascent, as suggested by changes in lung mechanics. We, therefore, investigated whether changes in lung mechanics consistent with fluid accumulation at h...

BACKGROUND It is unclear why obesity is associated with worse asthma control. We hypothesized that (1) obesity affects asthma control independent of spirometry, airway inflammation, and airway hyperresponsiveness (AHR) and (2) residual symptoms after resolution of inflammation are due to obesity-related changes in lung mechanics. METHODS Forty-nine subjects with asthma underwent the following...

Psychological reactance (Brehm, 1966; Brehm & Brehm, 1981) has been a long-standing topic of interest among scholars studying the design and effects of persuasive messages and campaigns. Yet, until recently, reactance was considered to be a motivational state that could not be measured. Dillard and Shen (2005) argued that reactance can be conceptualized as cognition and affect and made amenable...

OBJECTIVE Plexiform neurofibromas (PNs) are complex, benign nerve sheath tumors that occur in approximately 25%-50% of individuals with neurofibromatosis type 1 (NF1). PNs that cause airway compromise or pulmonary dysfunction are uncommon but clinically important. Because improvement in sleep quality or airway function represents direct clinical benefit, measures of sleep and pulmonary function...

This manuscript reports 2 experiments that were conducted to test and extend the work of J. P. Dillard and L. Shen (2005) examining the cognitive and affective processes involved in psychological reactance. In particular, the studies reported here (a) examined the best-fitting model of reactance processes and (b) tested 3 factors that may affect reactance including argument quality, severity of...

Spirometry is considered the primary method to detect the air flow limitation associated with obstructive lung disease. However, air flow limitation is the end-result of many factors that contribute to obstructive lung disease. One of these factors is increased airway resistance. Airway resistance is traditionally measured by relating air flow and driving pressure using body plethysmography, t...

Previous research has demonstrated a considerable amount of negative consequences resulting from psychological reactance. The purpose of this study was to explore opportunities to reduce the amount of reactance. Using the method of perspective taking as an intervention, the current study of 196 Austrians and 198 Filipinos examined whether reactance could be reduced and whether individualists an...

The mechanism by which deep inspirations protect against increased airway responsiveness in nonasthmatic subjects is not known. The aim was to investigate the role of airway closure and airway narrowing in deep inspiration bronchoprotection. Twelve nonasthmatic and nine asthmatic subjects avoided deep inspirations (DI) for 20 min, then took five DI expired to functional residual capaciy (DI-FRC...
