Characterizing respiratory rate variability (RRV) in humans during sleep is challenging, since it requires the analysis of respiratory signals over a period of several hours. These signals are easily distorted by movement and volitional inputs. We applied the method of spectral analysis to the nasal pressure transducer signal in 38 adults with no obstructive sleep apnea, defined by an apnea‐hypopnea index <5, who underwent all‐night polysomnography (PSG). Our aim was to detect and quantitate RRV during the various sleep stages, including wakefulness. The nasal pressure transducer signal was acquired at 100 Hz and consecutive frequency spectra were generated for the length of the PSG with the Fast Fourier Transform. For each spectrum, we computed the amplitude ratio of the first harmonic peak to the zero frequency peak (H1/DC), and defined as RRV as (100 − H1/DC) %. RRV was greater during wakefulness compared to any sleep stage, including rapid‐eye‐movement. Furthermore, RRV correlated with the depth of sleep, being lowest during N3. Patients spent most their sleep time supine, but we found no correlation between RRV and body position. There was a correlation between respiratory rate and sleep stage, being greater in wakefulness than in any sleep stage. We conclude that RRV varies according to sleep stage. Moreover, spectral analysis of nasal pressure signal appears to provide a valid measure of RRV during sleep. It remains to be seen if the method can differentiate normal from pathological sleep patterns.

Pediatrics Faculty Publications

BACKGROUND:

Innate immune responses are fine-tuned by small noncoding RNA molecules termed microRNAs (miRs) that modify gene expression in response to the environment. During acute infections, miRs can be secreted in extracellular vesicles (EV) to facilitate cell-to-cell genetic communication. The purpose of this study was to characterize the baseline population of miRs secreted in EVs in the airways of young children (airway secretory microRNAome) and examine the changes during rhinovirus (RV) infection, the most common cause of asthma exacerbations and the most important early risk factor for the development of asthma beyond childhood.

METHODS:

Nasal airway secretions were obtained from ...


Effects Of Prenatal Exposure To Bisphenol A On Fetal Lung Development, Ayten Hijazi 2016 The University of Western Ontario

Effects Of Prenatal Exposure To Bisphenol A On Fetal Lung Development, Ayten Hijazi

Electronic Thesis and Dissertation Repository

Prenatal exposure to bisphenol A (BPA), one of the most prevalent endocrine disrupting chemicals, is associated with lung dysfunction and diseases in later life. However, it is unknown if this association has a fetal origin. In this thesis, a series of in vivo and in vitro experiments were conducted to determine the effects of prenatal exposure to BPA on fetal lung development, and define the underlying molecular mechanisms. Environmentally relevant doses of BPA were administered to pregnant mice via diet from embryonic day (E) 7.5 to 18.5. Fetal lungs were analyzed at E18.5 for changes in structure ...

Alpha-1 antitrypsin (AAT) deficiency is a common monogenic disorder resulting in emphysema, which is currently treated with weekly infusions of protein replacement. We previously reported achieving plasma wild-type (M) AAT concentrations at 2.5-3.8% of the therapeutic level at 1 year after intramuscular (IM) administration of 6×1012vg/kg of a recombinant adeno-associated virus serotype 1 (rAAV1)-AAT vector in AAT-deficient patients, with an associated regulatory T cell (Treg) response to AAV1 capsid epitopes in the absence of any exogenous immune suppression. Here, we report sustained expression at greater than 2% of the therapeutic level for 5 years after ...

Characterization Of Respiratory Phenotype In Very Long-Chain Acyl-Coa Dehydrogenase Deficient Mice., Allison M. Keeler, Kaitlyn Desrochers, Mai K. Elmallah

UMass Center for Clinical and Translational Science Research Retreat

Rationale: Very Long-chain Acyl-CoA dehydrogenase (VLCAD) deficiency the most common inherited long-chain fatty acid disorder. The VLCAD enzyme catalyzes the first step of mitochondrial fatty acid oxidation and loss of the enzyme results in energy deficiency as well as accumulation of long chain fatty acids. Recently, a related enzyme, Long-chain Acyl-CoA dehydrogensase (LCAD), which unlike VLCAD is not highly expressed in metabolic tissues like liver, heart and skeletal muscle, was found to be expressed in the lung and surfactant and lung dysfunction were observed in LCAD deficient mice. Respiratory distress syndrome has been described in other fatty acid oxidation disorders ...

The respiratory bacterial infection caused by Bordetella pertussis (whooping cough) is the only vaccine-preventable disease whose incidence has been increasing over the last 3 decades. To better understand the resurgence of this infection, a baboon animal model of pertussis infection has been developed. Naïve baboons that recover from experimental pertussis infection are resistant both to clinical disease and to airway colonization when re-challenged. In contrast, animals vaccinated with acellular pertussis vaccine and experimentally challenged do not develop disease, but airways remain colonized for 4-6 weeks. We explored the possibility that the IgG antibody response to pertussis infection is qualitatively different ...

Journal of Patient-Centered Research and Reviews

Pneumonia infection is a significant cause of morbidity and mortality worldwide. In addition to the public health concerns, pneumonia also accounts for a significant cost to the health care system. Currently there are two leading vaccines targeted against Streptococcus pneumoniae: 23-valent pneumococcal polysaccharide vaccine (PPSV23) and 13-valent pneumococcal conjugate vaccine (PCV13). Until recently, the recommendation for adult pneumonia vaccination has been a single dose of PPSV23 for all adults aged 65 years or older. However, concerns were raised regarding the vaccine’s efficacy due to the persistent burden of pneumococcal disease in the elderly population. This paper focuses on two ...

Pulmonary Imaging To Better Understand Asthma, Sarah Svenningsen 2015 The University of Western Ontario

Pulmonary Imaging To Better Understand Asthma, Sarah Svenningsen

Electronic Thesis and Dissertation Repository

Asthma is characterized using the spirometry measurement of the forced expiratory volume in one second (FEV1). Simple and inexpensive, FEV1 provides a global estimate of lung function but this metric cannot regionally identify airways responsible for airflow limitation, asthma symptoms or control. Work that brought about an understanding that airway abnormalities are heterogeneously distributed within the lung in asthma patients has motivated the development of pulmonary imaging approaches, such as hyperpolarized helium-3 (3He) and xenon-129 (129Xe) magnetic resonance imaging (MRI). These methods provide a way to visualize and quantify lung regions accessed by gas during a ...

METHODS: A two-stage community-based representative cross-sectional survey was conducted in Karachi from March 2012 to April 2013 comprising 1046 children aged 3-17 years. Of 7500 clusters, 80 were randomly selected, and of these, 15 children per cluster were enrolled randomly. A translated and pre-tested version of International Study ...


Hyperpolarized 129xe Magnetic Resonance Imaging Of Radiation-Induced Lung Injury, Ozkan Doganay 2015 The University of Western Ontario

Hyperpolarized 129xe Magnetic Resonance Imaging Of Radiation-Induced Lung Injury, Ozkan Doganay

Electronic Thesis and Dissertation Repository

Lung cancer is the largest contributor to cancer-related mortality worldwide. Only 20% of stage III non-small cell lung cancer patients survive after 5-years post radiation therapy (RT). Although RT is an important treatment modality for lung cancer, it is limited by Radiation-Induced Lung Injury (RILI). RILI develops in two phases: (i) the early phase (days-weeks) referred to radiation pneumonitis (RP), and (ii) the late phase (months). There is a strong interest in early detection of RP using imaging to improve outcomes of RT for lung cancer. This thesis describes a promising approach based on 129Xe gas as a contrast ...
