Multimodal Telemonitoring for Weight Reduction in Patients With Sleep Apnea: A Randomized Controlled Trial.

Background: Telemonitoring the use of CPAP devices and remote feedback on device data effectively optimizes CPAP adherence in patients with OSA.

Research Question: Can expanding the scope of telemonitoring and remote feedback to body weight (BW), BP, and physical activity enhance efforts for BW reduction in Patients with OSA receiving CPAP?

Study Design And Methods: Participants were recruited from patients at 16 sleep centers in Japan with OSA and obesity who were receiving CPAP therapy. Obesity was defined as a BMI of ≥ 25 kg/m, based on Japanese obesity guidelines.

Natural course and potential prognostic factors for sleep-disordered breathing in multiple system atrophy.

Objective/background: Multiple system atrophy (MSA) frequently results in the development of sleep-disordered breathing (SDB). Few reports have described the natural course of this phenomenon. The aim of the present study was to determine the natural course of SDB and prognostic factors associated with such conditions in MSA.

Facial axis angle as a risk factor for obstructive sleep apnea.

Objective: Many Japanese patients with obstructive sleep apnea (OSA) are less obese than Caucasian OSA patients despite their similar severity of OSA, suggesting that their etiology of OSA may differ. The purpose of this study was to identify bony factors associated with OSA in the Japanese population.

Methods: The clinical records of study subjects were retrospectively reviewed, and cephalometric measurements based on Sella-Nasion references and the Ricketts method were statistically compared.
