Sleep disordered breathing (SDB) is a common comorbidity in patients with atrial fibrillation (AF). Patients undergoing pulmonary vein isolation (PVI) for AF have a high prevalence of SDB. In previous studies, some patients with AF had Cheyne-Stokes respiration (CSR).

Characteristic clinical features included episodic hyperventilation followed by apnea from hypocapnia, which did not follow a Cheyne-Stokes pattern. Combined with the identification of cerebellar and brainstem malformations known as the "molar tooth sign" on a brain magnetic resonance imaging, developmental delay, and motor coordination problems, Joubert syndrome (a congenital disease) was first diagnosed at the age of 50 years.

However, whether female athletes with poor sleep quality based on subjective assessment have distinctive changes in objective measures of sleep in association with menses remains unclear. This study aimed to compare changes in objective sleep measurements during and following menses between collegiate female athletes with and without poor subjective sleep quality.

- Overnight increases in arterial stiffness, measured by cardio-ankle vascular index (CAVI), were linked to sleep-disordered breathing in patients with acute heart failure.
- Significant overnight changes in blood pressure and CAVI were observed in a study of 60 hospitalized patients, with CAVI rising from 8.4 to 9.1.
- The majority of patients with increased CAVI (70%) were more likely to have moderate-to-severe sleep-disordered breathing, suggesting that respiratory issues may significantly contribute to increased arterial stiffness during hospitalization for heart failure.
Background: In recent years, a relatively high prevalence of obstructive sleep apnea (OSA) in patients following radiotherapy (RT) for head and neck cancer (HNC) has been reported; however, little is known regarding the impact of RT on sleep disorders and the underlying mechanisms. This aim of this study was to elucidate the pathogenesis of OSA by comparing the clinical and sleep test parameters and magnetic resonance imaging (MRI) findings before and after HNC treatment with radiation.
Methods: This prospective study included patients scheduled for RT with or without chemotherapy or bioradiotherapy for HNC.
