Sleep and long COVID: preexisting sleep issues and the risk of PASC in a large general population using 3 different model definitions.

Study Objectives: Insomnia, poor sleep quality and extremes of sleep duration are associated with COVID-19 infection. This study assessed whether these factors are related to Post-Acute Sequelae of SARS-CoV-2 infection (PASC).

Methods: Cross-sectional survey of a general population of 24,803 U.

Obstructive Sleep Apnea is a Risk Factor for Incident COVID-19 Infection.

Cross-sectional studies suggest that obstructive sleep apnea (OSA) is a potential risk factor for incident COVID-19 infection, but longitudinal studies are lacking. In this study, two surveys from a large general population cohort, the COVID-19 Outbreak Public Evaluation (COPE) Initiative, undertaken 147 ± 58 days apart were analyzed to determine whether the pre-existing OSA was a risk factor for the incidence of COVID-19. Of the 24,803 respondents completing the initial survey, 14,950 were negative for COVID-19; data from the follow-up survey were available for 2,325 respondents.

Association of Chronotype and Shiftwork With COVID-19 Infection.

This study assesses whether chronotype is related to COVID-19 infection and whether there is an interaction with shift work. Methods: This study used a cross-sectional survey of 19,821 U.S.

Association of Obstructive Sleep Apnea with Post-Acute Sequelae of SARS-CoV-2 Infection.

Background: Obstructive sleep apnea is associated with COVID-19 infection. Less clear is whether obstructive sleep apnea is a risk factor for the development of post-acute sequelae of SARS-CoV-2 infection (PASC).

Study Design: Cross-sectional survey of a general population of 24,803 US adults to determine the association of obstructive sleep apnea with PASC.

Association of Obstructive Sleep Apnea with Post-Acute Sequelae of SARS-CoV-2 infection (PASC).

Background: Obstructive sleep apnea (OSA) is associated with COVID-19 infection. Fewer investigations have assessed OSA as a possible risk for the development of Post-Acute Sequelae of SARS-CoV-2 infection (PASC).

Research Question: In a general population, is OSA associated with increased odds of PASC-related symptoms and with an overall definition of PASC?

Objective: This study assesses whether chronotype is related to COVID-19 infection and whether there is an interaction with shift work.

Associations between obstructive sleep apnea and COVID-19 infection and hospitalization among US adults.

Study Objectives: Medical comorbidities increase the risk of severe COVID-19 infection. In some studies, obstructive sleep apnea (OSA) has been identified as a comorbid condition that is associated with an increased prevalence of COVID-19 infection and hospitalization, but few have investigated this association in a general population. This study aimed to answer the following research question: In a general population, is OSA associated with increased odds of COVID-19 infection and hospitalization and are these altered with COVID-19 vaccination?

Methods: This was a cross-sectional survey of a diverse sample of 15,057 US adults.

Insomnia, Poor Sleep Quality and Sleep Duration, and Risk for COVID-19 Infection and Hospitalization.

Background: Medical comorbidities increase the risk of severe acute COVID-19 illness. Although sleep problems are common after COVID-19 infection, it is unclear whether insomnia, poor sleep quality, and extremely long or short sleep increase risk of developing COVID-19 infection or hospitalization.

Methods: The study used a cross-sectional survey of a diverse sample of 19,926 US adults.

Portable evaluation of obstructive sleep apnea in adults: A systematic review.

Obstructive sleep apnea (OSA) is a significant healthcare burden affecting approximately one billion people worldwide. The prevalence of OSA is rising with the ongoing obesity epidemic, a key risk factor for its development. While in-laboratory polysomnography (PSG) is the gold standard for diagnosing OSA, it has significant drawbacks that prevent widespread use.

Silver nitrate therapy for persistent tracheocutaneous fistula following prolonged tracheostomy and invasive ventilation: A case report.

We report the case of a man with severe Guillain-Barré syndrome who developed a persistent tracheocutaneous fistula (TCF) following prolonged tracheostomy and mechanical ventilation. Following tracheostomy decannulation, the TCF had a deleterious effect on non-invasive positive pressure ventilation efficacy and ability to effectively clear airway secretions due to air leaking from the patent stoma. This case highlights a non-surgical approach to TCF management that is not well-described in the literature and presents an alternative management option for cohorts of patients in which the risk associated with surgical interventions may be undesirable.

Filters Alter the Performance of Noninvasive Ventilators.

Background: Noninvasive ventilation is recommended in hypercapnic respiratory failure secondary to ventilatory failure. Noninvasive ventilation may contribute to aerosol dispersion, which may increase the risk of transmission of COVID 2019. The addition of filters to the ventilator circuit has been recommended to reduce this risk.

Impact of smoking status and chronic obstructive pulmonary disease on pulmonary complications post lung cancer surgery.

Introduction: Smoking and chronic obstructive pulmonary disease (COPD) are associated with an increased risk of post-operative pulmonary complications (PPCs) following lung cancer resection. It remains unclear whether smoking cessation reduces this risk.

Methods: Retrospective review of a large, prospectively collected database of over 1000 consecutive resections for lung cancer in a quaternary lung cancer centre over a 23-year period.

Teaching Radial Endobronchial Ultrasound with a Three-Dimensional-printed Radial Ultrasound Model.

Background: Peripheral pulmonary lesion (PPL) incidence is rising because of increased chest imaging sensitivity and frequency. For PPLs suspicious for lung cancer, current clinical guidelines recommend tissue diagnosis. Radial endobronchial ultrasound (R-EBUS) is a bronchoscopic technique used for this purpose.
