Full textIncludes bibliographical references (p. 133-137).
This research characterizes the respiratory system dynamics at the initiation and termination of utterances and determines correlations of physiological measures with acoustic cues for these prosodic boundaries. The analysis includes boundaries within a breath as well as boundaries that are aligned with the initiation and termination of exhalation. Simultaneous recordings of the acoustic signal, airflow, esophageal pressure and lung volume were collected during read isolated utterances and short paragraphs. These measures were used to derive estimates of recoil forces of the chest wall, net muscular forces, and the area of the airway constriction. Data are presented from four subjects (two men, two women), all native speakers of American English. Perceptual ratings for initial and final prominent syllables and the locations of pauses within the utterance were also collected. For speech boundaries th.i.t are aligned with breath boundaries, utterance initiation occurs during a rapid transition in muscular effort. Sound begins as soon as conditions permit and these conditions consistently occur during net inspiratory muscular force. Alveolar pressure reaches an initial peak (PpI) that is, in most cases, correlated to the relaxation characteristic of the chest wall. The timing of Pp1 generally coincides with a prominent syllable if that syllable is the first or second syllable in the utterance and precedes later prominences. Pressure at phonation onset is, on average, near 0.3PpI for utterances initiated with a voiced sonorant and is near 0. 8Pp1 for utterances initiated with a voiceless fricative. Phonation termination results from an approximately 3-fold increase in glottal area and a J-3 cm H20 fall in pressure. Irregular fundamental frequency (FO) at the end of voicing, in many cases, does not fit the classical definition of glottalization. Instead, voicing terminates with increasing glottal area, and FO becomes irregular during the increase. In some cases, regular FO resumes as glottal area continues to increase. Distinct respiratory gestures are made at pauses within a breath. The pressure is reduced by 2-3 cm H20, on average, during a period of relatively little volume change. The findings in this research show that the role of the respiratory system in speech production goes beyond a more traditional view of this role as one of simply providing a relatively constant driving pressure during speech.

Full textThe undertaken study consisted of an initial pre-exposure assessment survey and two follow-up reassessment surveys that took place between September 1998 and June 2001. During these surveys a series of tests were carried out. These included a respiratory symptom questionnaire as well as a systemic symptom questionnaire, skin prick tests, spirometry and methacholine challenge tests. Industrial hygiene sampling for welding fumes in the breathing zone of these students was also performed. The overall results of the epidemiological study are presented in three interrelated manuscripts.
The first manuscript describes in detail the underlying methodology. In addition, it provides incidence figures, which are lacking in the reviewed literature, for the outcomes of interest described afterwards. The second manuscript determined the incidence of bronchial hyperresponsiveness (BHR) and the increase in airway obstruction from baseline values. The third manuscript confirmed our earlier findings (1) of a strong association between welding-related MFF and welding-related respiratory symptoms suggestive of OA. (Abstract shortened by UMI.)

Full textRoutinely monitored independent variables, derived from various government databases, included temperature, relative humidity, ozone, nitrogen dioxide, sulfur dioxide, coefficient of haze, and measures of particulate pollution, several of which were recorded only every sixth day. To permit a daily time series analysis, levels for the missing 5 days were modelled using meteorologic and other pollutant variables.
To control for confounding by season, the dependent and independent time series were detrended using a weighted 19-day moving average linear filter. To control for confounding by day-of-week cycles, the dependent series were pre-filtered with day-of-week indicator variables.
For the July to August periods, statistically significant relationships were shown for all respiratory admissions to 8-hour maximal average ozone levels 4 days prior to the admission day, relationships which were however confounded by temperature of the same lag day. After controlling for temperature, admissions for asthma, and for respiratory illnesses other than asthma, were significantly associated with particulate levels 2 to 4 days prior to the admission day for the warm but not the cold periods. Stronger associations were found using a filter which did not remove month-to-month temporal trends. A significant correlation of non respiratory admissions to particulate levels on the day of admission was confounded by temperature and relative humidity.
These results suggest that particulate air pollution, possibly acidic, during photochemically active periods is related to respiratory morbidity in Montreal. The effects shown, at levels mostly below current ambient air quality standards in North America, are relevant to public health, since hospital admissions are likely to reflect more frequent episodes of less serious illness.

Full textBecause skeletal muscles can express a variety of immune modulating molecules such as cytokines, chemokines, adhesion molecules, and major histocompatibility molecules, the objective of the second study in this thesis was to study the possible role of pro-inflammatory cytokines in diaphragm muscle dysfunction in our animal model. Our results indicate for the first time that intra-diaphragmatic pro-inflammatory cytokine gene expression (TNF-alpha, IL-1alpha, IL-1beta, IL-6, and IL-18) is highly up-regulated in infected animals and the magnitude of such upregulation is dependent upon the dose of P. aeruginosa lung infection. Parallel to the absence of muscle contractile dysfunction in hindlimb muscle under the same conditions, P. aeruginosa infection did not alter the levels of pro-inflammatory gene expression within the hindlimb muscle. To further address the involvement of muscle-derived pro-inflammatory cytokines in diaphragmatic contractile dysfunction, we have employed recombinant adenovirus (Ad) as a vehicle for systemic delivery of the anti-inflammatory cytokine IL-10, in order to shift the balance between pro- and anti-inflammatory cytokines within the diaphragm toward a more anti-inflammatory profile. We report here that systemic delivery of Ad-IL-10 suppresses pro-inflammatory gene expression and improves force generating capacity of the diaphragm in P. aeruginosa infected animals. This finding emphasizes the role of anti-inflammatory cytokines as beneficial immune modulators in respiratory muscle failure caused by pro-inflammatory cytokines.
P. aeruginosa lung infection is a major cause of morbidity and mortality among cystic fibrosis (CF) patients and many patients with CF have weak peripheral and respiratory muscles. Although the role of pro-inflammatory cytokines has been extensively studied within the lungs of CF patients, the involvement of these cytokines in skeletal muscle dysfunction in animal models of CF or in human CF patients has not been studied. Therefore, in the third study of this thesis we have used mice sharing the same genetic defect as CF patients (Cftr knockout mice), in combination with our model of P. aeruginosa lung infection, to address several fundamental questions related to muscle function in CF. Our first objective in this portion of the thesis was to determine if diaphragmatic skeletal muscle cells express the CFTR mRNA. Our second objective was to ascertain whether intrinsic differences between CF and wild-type muscle cells could be detected in vitro, which might differentially affect the regulation of pro-inflammatory mediators in the setting of infection/inflammation. Our third objective was to evaluate possible differences in the ability of respiratory muscles to generate force prior to and after P. aeruginosa lung infection in Cftr knockout mice, as compared to their wild-type littermates. Finally, we aimed to determine if the absence of CFTR expression would predispose to muscle dysfunction triggered by up-regulation of intra-diaphragmatic pro-inflammatory gene expression. Our major results indicate that: First, in vitro stimulation with pro-inflammatory cytokines (TNF-alpha, IL-1alpha, and IFN-gamma) and LPS (extracted from Pseudomonas aeruginosa) triggered increased expression of pro-inflammatory mediators (iNOS, RANTES, MIP-1alpha, MIP-1beta, MIP-2 and KC) in both Cftr -/- and wild-type diaphragmatic myotubes, but the magnitude of cytokine/chemokine upregulation was significantly greater in CF than in wild-type diaphragm muscle cells. Sec
In the final study of this thesis, we sought to test the hypothesis that increased diaphragm muscle activation would lead to increased production of intra-diaphragmatic cytokine expression, since this could possibly explain the greater susceptibility of the diaphragm to express pro-inflammatory cytokines in response to pulmonary P. aeruginosa infection as compared with the hindlimb muscle. To test this hypothesis, we subjected rats to inspiratory resistive loading (IRL), corresponding to 45-50% of the maximum inspiratory pressure, and described that mRNA levels of IL-1beta, IL-6, and to a lesser extent, IL-4, IL-10, TNF-alpha, and IFN-gamma were all significantly increased in a time-dependent fashion in the diaphragm but not hindlimb muscle (gastrocnemius) of loaded animals. In addition, elevated protein levels of IL-1beta and IL-6 in response to loading were confirmed with immunoblotting and immunostaining. We also detected significant IL-6 protein to be localized inside diaphragmatic muscle fibers of loaded animals. We conclude that increased diaphragm muscle activity during resistive loading induces upregulation of pro-inflammatory cytokine gene expression in the diaphragm, which could also provide an explanation for the greater cytokine expression observed in the diaphragms of animals with P. aeruginosa lung infection.

One hundred ninety four steers, bulls, and heifers weighing 182-318 kg were purchased at an Arkansas sale barn and shipped 12 hours to a northern Kansas feedlot. There was no previous history of treatment and the cattle had been delivered to the sale barn within the 24 hour period prior to the sale. The objectives of the study were to evaluate (1) bacterial pathogen isolates in different locations in the respiratory tract, (2) pathogen load in clinically ill and clinically normal calves, and (3) compare histological damage that may be a result of clinical disease. Fifteen calves were identified with signs of acute bovine respiratory disease (BRD) based on clinical score and a minimum rectal temperature of 40° C. An additional 5 calves with no clinical signs and rectal temperatures < 40° C were selected as controls. Cattle were humanely euthanized following recording of antemortem clinical observations. At postmortem, samples for microbiologic and histologic (hematoxylin and eosin stain) analysis were collected from grossly normal and/or consolidated tissue in each lung lobe. Samples were also collected from the tonsils and trachea. Quantification of the BRD pathogens per gram were determined for each positive site and then converted to total counts for each animal. Total colony forming units (CFU) of pathogens in the entire lung for cattle with identified pathogens ranged from 2x10[superscript]7 – 2x10[superscript]8 CFU for Pasturella multocida and 9x10[superscript]6 – 9x10[superscript]8 CFU for Mannheimmia haemolytica. Total visual estimated percent consolidation ranged from 0.0% to 45.0% of the total lung. Isolated pathogens from the upper and lower respiratory tract were compared and showed to have no significant agreement. Histology scores of 0-4 were assigned to the tissue samples and compared to the quantified BRD pathogens to test a possible association between the pathologic process and the total agents in that tissue sample. A significant difference in bacterial counts between histology scores of zero or 1 and a histology score of 4 was observed.
