To investigate the associations between obstructive sleep apnea (OSA) and coronavirus disease 2019 (COVID-19) severity. Twelve individuals hospitalized in a Brazilian tertiary hospital diagnosed with COVID-19 by reverse transcriptase-polymerase chain reaction (RT-PCR) underwent respiratory polygraphy. Polygraphic records identified seven participants without obstructive sleep apnea (OSA) (OSA-) and five with OSA (OSA + ). The OSA+ group presented worse peripheral oxygen saturation (77.6% ± 7.89%) than the OSA- group (84.4% ± 2.57%) ( = 0.041). Additionally, the OSA+ group showed greater COVID-19 severity (100%) than the OSA- group (28.57%) ( = 0.013) and required longer oxygen therapy ( = 0.038), but without difference in the length of hospitalization. The OSA+ group also presented higher rates of platelets ( = 0.008) and D-dimer (1,443 ± 897) than the OSA- group (648 ± 263 ng/mL) ( = 0.019). Obstructive sleep apnea in individuals hospitalized due to COVID-19 was associated with higher COVID-19 severity, worse peripheral oxygen saturation, longer oxygen therapy time, and higher platelet and D-dimer rates.

Purpose: In heart failure (HF) and chronic obstructive pulmonary disease (COPD) populations, sleep-disordered breathing (SDB) is associated with impaired health outcomes. We evaluated whether in patients with HF, concomitant HF and COPD or COPD, the number of hospitalizations would be reduced in the year after testing for SDB with and without treatment initiation compared to the year before.
Methods: We performed a multicentre retrospective study of 390 consecutive sleep-clinic patients who had a primary diagnosis of chronic HF, HF and COPD or COPD and a secondary diagnosis of SDB.

In 2024, several important innovations have enriched the management of respiratory diseases, including pulmonary hypertension, tuberculosis, COPD, and obstructive sleep apnea syndrome (OSAS). Notable advancements include the introduction of sotatercept in Switzerland for pulmonary arterial hypertension and mediastinal cryobiopsies, reflecting a shift toward more personalized medicine. Meanwhile, biologic therapies for COPD offer promising perspectives, and a potential path is emerging for shortening the treatment of certain forms of tuberculosis.

Objective: To investigate the risk of obstructive sleep apnea (OSA) in patients with muscle tension dysphonia (MTD) in comparison to subjects with no dysphonia.
Study Design: Prospective cohort study.
Methods: Patients who were diagnosed with MTD at a tertiary referral center between October 2022 and October 2023 were invited to participate in this study, alongside a healthy control group matched by age and gender, with no history of dysphonia.
