Despite growing recognition of the need for increased diversity among students, trainees, and faculty in health care, medical workforce still lacks adequate representation from groups historically underrepresented medicine (URiM). The subspecialty field pediatric pulmonology is no exception. Although there have been efforts to address issues diversity, equity, inclusion (DEI) our own field, gaps persist. To these gaps, members Diversity, Equity, Inclusion Advisory Group (DEI-AG) American...
In children, obesity typically reduces functional residual capacity (FRC), which airway caliber and increases resistance. Whether these obesity-related changes in respiratory function can alter bronchodilator responsiveness is unknown.To investigate nonasthmatic children with without obesity.Seventy 8-12 years old, (n = 19) 51) obesity, completed spirometry, impulse oscillometry, resistance measurements through plethysmography pre/post 360 µg of inhaled albuterol. FRC was assessed pre A...
Study Objective: Physical fitness (i.e., VȮ 2max in ml/min/kg) is decreased children with obesity. However, cardiorespiratory 2 max as a percent of predicted based on ideal body mass) preserved Unfortunately, many obesity suffer from obesity-related respiratory symptoms such exertional dyspnea, which could make them reluctant to exercise and thus decrease both their physical fitness. Thus, we hypothesized that will be symptoms. Methods: Body composition (DXA) was measured aged 8-12yrs...
Little is known about whether body composition changes differently between children with and without obesity following 1 year of nonintervention. Therefore, we investigated in early pubescent (8-12 yr) before after a period Early yr; Tanner stage ≤ 3) (body mass index, BMI ≥ 95th percentile) (15th < 85th were recruited. At baseline, 88 (
Determine whether preterm-born adolescents and adults have sleep-disordered breathing (SDB), as documented by abnormal overnight oximetry.
Abstract Introduction Cheyne-Stokes Respiration (CSR) is a form of central sleep apnea (CSA) characterized by periods hyperventilation and apneas or hypopneas. This case full-term neonate who presented with acute respiratory failure, requiring ECMO, secondary to late-onset sepsis Legionella infection. Polysomnography (PSG) obtained post ECMO decannulation showed CSR. rare finding in neonates the causes, prevalence, progression, outcomes CSA-CSR pediatric population remains unclear. Report...
Introduction The purpose of this study was to examine whether maximal oxygen uptake (V̇O 2max ) prediction equations based on lean body mass can overcome the confounding effect fat quantification cardiorespiratory fitness in children with obesity. Methods Forty‐nine (23 obesity; BMI ≥ 95th percentile) completed a dual‐energy x‐ray absorptiometry scan for estimating composition and incremental verification exercise tests till volitional exhaustion V̇O . Prediction (LBM) from Cooper D.M. et al...
PURPOSE: Increases in external dead space augment the exercise ventilatory response independent of potential respiratory effects sex and obesity. Therefore, imposed by mouthpiece breathing valve (VDM) should be accounted for when comparing response, particularly prepubescent children who have smaller lungs. We evaluated impact VDM on defined as slope relation between minute ventilation (V̇E) carbon dioxide (V̇CO2), obese nonobese boys girls. METHODS: 27 (age: 10 ± 1 y; height: 146 8 cm;...
PURPOSE: The effect of albuterol on β2-adrenoceptor activation is usually assessed by a significant increase in forced expiratory volume one second (FEV1). However, even without FEV1, an isovolume flow between 25% and 75% (isoFEF25-75) vital capacity (FVC) would allow for greater exercise tidal rates thus increasing ventilatory (V̇Ecap). This could be particularly important children with obesity, who breathe at low lung volumes have limited reserves. We examined if isoFEF25-75 V̇Ecap...
