Gestational hypertension is a common complication of pregnancy. Recent evidence suggests that women with gestational have high rate sleep disordered breathing (SDB). Using laboratory-based polysomnography, we evaluated for the frequency SDB in compared to healthy uncomplicated pregnancies. In this single-center cross-sectional study, diagnosis were screened Fetal Assessment Unit and Antepartum ward. Healthy subjects recruited by local advertising. Subjects completed series questionnaires...
BACKGROUND: Obesity rates are increasing worldwide, particularly in North America. The impact of obesity on the outcome critically ill patients is unclear. METHODS: A prospective observational cohort study consecutive admitted to a tertiary critical care unit Canada between January 10, 2008 and March 31, 2009 was conducted. Exclusion criteria were age <18 years, admission <24 h, planned cardiac surgery, pregnancy, significant ascites, unclosed surgical abdomen brain death admission....
Obstructive sleep apnea is a common condition within the Canadian population. The current gold standard for diagnosis and management of patients in-laboratory (in-lab) polysomnography; however, limited availability testing options has led to long wait times increased disease burden Sleep Research Laboratory in Saskatoon (Saskatchewan) implemented home program run parallel with in-lab system several years ago an effort increase their capacity reduce times. present study was retrospective...
To compare a commercially available, level III in-home diagnostic sleep test (Embletta, Embletta USA) and in-laboratory polysomnography (PSG) in women with suspected obstructive apnea (OSA).Consecutive scheduled for routine PSG testing evaluation of clinically OSA who met inclusion⁄exclusion criteria, were invited to participate. An portable monitor was performed one week before or after PSG.Forty-seven 96 the criteria agreed The mean (± SD) age patients 52.0 ± 11.0 years, body mass index...
Gestational hypertension (GH) is a newly recognized risk factor for adverse cardiovascular events later in life. Sleep disordered breathing (SDB) an established events. Recent research has suggested that women with GH may have increased rate of SDB during pregnancy, but it not known if this higher persists into the postpartum state.To assess whether continue to compared healthy pregnant women, after physiologic changes pregnancy resolve.We previously studied and uncomplicated pregnancies...
Recent evidence suggests that women with gestational hypertension (GH) have a high rate of sleep disordered breathing (SDB), and treatment for even marginal SDB may improve blood pressure control in GH. We assessed whether the application could GH.This was single-center randomized study. Subjects underwent an unattended home-based diagnostic The study then repeated subjects wearing one two randomly assigned treatments: auto-titrating continuous positive airway (auto-CPAP) or mandibular...
To evaluate various aspects of the management adult patients who present to emergency department with acute exacerbations asthma and are discharged from without hospital admission. Further, compare results accepted guidelines for treatment asthma.A retrospective chart collection review until each site contributed 50 survey.Three tertiary care hospitals in Saskatoon Health District, Saskatoon, Saskatchewan. The study period was July 1, 1997 November 18, 1997.Patients aged 17 years or older,...
BACKGROUND: Loss of bronchoprotection routinely follows regular treatment with beta 2 ‐agonists. There are no data on the effects for thrice weekly use a ‐agonist. METHODS: A double‐blind, randomized, placebo controlled crossover trial was conducted to investigate administration 12 μg formoterol versus against methacholine. As an expected positive control, once daily also evaluated. RESULTS: significant difference in bronchoprotective administered day 8, following seven days or every other...
BACKGROUND: Standard practice in obstructive sleep apnea (OSA) management requires that a positive diagnostic, overnight polysomnography (PSG) test be obtained before initiating treatment. However, long waiting times due to lack of access PSG testing facilities may delay the initiation definitive treatment for OSA. OBJECTIVES: To evaluate response patients who had high clinical suspicion OSA and were an empirical continuous airway pressure (CPAP) trial. METHODS: A retrospective study all...
Chyloptysis, in the context of middle lobe syndrome, and chylothorax are rare clinical entities. They reported medical literature mostly as case reports, but never together same patient. The present report describes a 34-year-old woman who presented with chyloptysis associated recurrent right syndrome since she was 20 years age, eventually underwent lobectomy. A few weeks postoperatively, developed right-sided chylothorax, which refractory to therapy, successfully treated thoracic duct...
Background. Mild obstructive sleep apnea is common in pregnancy and may have an exacerbating role gestational hypertension, although currently the interaction between these two diseases uncertain. Methods. We analyzed 43 pregnant subjects, 28 with hypertension (GH) 15 normal healthy pregnancy, by level I polysomnography. Additionally, diastolic systolic blood pressure changes response to respiratory events were measured noninvasive beat-by-beat monitoring. also assessed a subgroup (<mml:math...
Obstructive sleep apnea (OSA) is increasingly recognized as a public health concern. Definitive diagnosis by overnight polysomnographic (PSG) examination. Identification of clinical predictors would be beneficial in helping prioritize high-risk patients for assessment. Practical application morphometric predictive variables require high level reproducibility setting. In this study, our objective was to evaluate reliability between observers measurements candidate parameters women.This...
