Effect of particulate matter on continuous positive airway pressure adherence in obstructive sleep apnea patients.

Background: Sleep quality could be affected by air pollution, especially for particulate matter with a diameter of less than 10 microns (PM) and particulate matter with a diameter of less than 2.5 microns (PM). However, no direct study demonstrates the relationship and impact of air pollution especially PM and PM on continuous positive airway pressure (CPAP) adherence.

Factors influencing continuous positive airway pressure adherence in elderly with obstructive sleep apnea.

Background: Continuous positive airway pressure (CPAP) is the most effective treatment for symptomatic obstructive sleep apnea (OSA). The identification of actual predictors of CPAP adherence in real-world practice is essential since it enhances more individualized management for the patient. CPAP acceptance and adherence in elderly patients with OSA have the same challenges but the conclusion remains unclear.

Implications of the Presence of Hyperdense Middle Cerebral Artery Sign in Determining the Subtypes of Stroke Etiology.

Background: Identifying stroke subtypes is crucial in choosing appropriate treatment, predicting outcomes, and managing recurrent stroke prevention.

Objectives: To study the association of hyperdense middle cerebral artery sign (HMCAS) on noncontrast computed tomography (NCCT) brain and subtypes of stroke etiology.

Methods: This is a retrospective hypothesis testing study.

Prevalence and Clinical Characteristics of Probable REM Behavior Disorder in Thai Parkinson's Disease Patients.

Background: Previous studies have shown that Parkinson's disease (PD) patients who have REM behavior disorder (PD with RBD) might be a PD subtype since they have different symptom clusters and disease trajectories from PD without RBD.

Objective: To study the prevalence of PD with pRBD and to compare the clinical characteristics with PD without pRBD. The feasibility of clinical interview of items adopted from the Mayo Sleep Questionnaire was also to be determined.
