Sleep characteristics in health workers exposed to the COVID-19 pandemic.

Introduction: The development of sleep disorders, and specifically insomnia, has been linked to the exposure to different stressors. In this line, Coronavirus disease 2019 (COVID-19) outbreak caused by the new coronavirus SARS-CoV-2, has caused a huge impact on our environment, and has exposed healthcare workers to an unprecedented threat. In this study, we try to assess sleep quality and the development of sleep disorders in health personnel directly dedicated to the care of COVID-19 patients at the height of the pandemic, compared to the general population.

[High level of student smokers in Madrid compared with a similar previous study of 2014].

Unlabelled: Smoking is a public health problem that affects young people, and influenced by the environment and cultural level.

Objectives: To determine smoking prevalence among high-level baccalaureate students in the Autonomous Community of Madrid during the 2018-2019 academic year. To assess the influence of the socio-cultural environment on the onset of youth smoking.

[Smoking Prevalence in High School Students in the Barcelona Region (De Osona District)].

Unlabelled: The socio-cultural setting influences youth smoking and its prevalence presumibly has decreased.

Objectives: To assess smoking prevalence in high school students, as well as the environmental influence on its onset in the Osona Disrtict of Barcelona (ODB), and to determine whether it has decreased.

Material And Methods: A cross-sectional study was conducted on high school students in the ODB.

Conventional Polysomnography Is Not Necessary for the Management of Most Patients with Suspected Obstructive Sleep Apnea. Noninferiority, Randomized Controlled Trial.

Rationale: Home respiratory polygraphy may be a simpler alternative to in-laboratory polysomnography for the management of more symptomatic patients with obstructive sleep apnea, but its effectiveness has not been evaluated across a broad clinical spectrum.

Objectives: To compare the long-term effectiveness (6 mo) of home respiratory polygraphy and polysomnography management protocols in patients with intermediate-to-high sleep apnea suspicion (most patients requiring a sleep study).

Methods: A multicentric, noninferiority, randomized controlled trial with two open parallel arms and a cost-effectiveness analysis was performed in 12 tertiary hospitals in Spain.

Non-invasive ventilation in obesity hypoventilation syndrome without severe obstructive sleep apnoea.

Background: Non-invasive ventilation (NIV) is an effective form of treatment in patients with obesity hypoventilation syndrome (OHS) who have concomitant severe obstructive sleep apnoea (OSA). However, there is a paucity of evidence on the efficacy of NIV in patients with OHS without severe OSA. We performed a multicentre randomised clinical trial to determine the comparative efficacy of NIV versus lifestyle modification (control group) using daytime arterial carbon dioxide tension (PaCO2) as the main outcome measure.
