Reliability of commercially available sleep and activity trackers with manual switch-to-sleep mode activation in free-living healthy individuals.

Introduction: Wearable health devices have become trendy among consumers, but it is not known whether they accurately measure sleep and physical activity parameters. To address this question, we have studied the measured data of two consumer-level activity monitors (Up Move Jawbone (U) and Withings Pulse 02 (W)) and compared it with reference methods for sleep and activity recordings, namely the Bodymedia SenseWear Pro Armband actigraph (SWA) and home-polysomnography (H-PSG).

Methods: Twenty healthy patients were assessed at home, during sleep, with the four devices.

Improvement of sleep architecture parameters in cirrhotic patients with recurrent hepatic encephalopathy with the use of rifaximin.

Background And Aim: Sleep disorders are frequently reported in patients with cirrhosis and hepatic encephalopathy (HE). This study assessed the effect of rifaximin on sleep architecture parameters in patients with recurrent HE.

Patients And Methods: This sequential, prospective, and exploratory study involved all patients with cirrhosis and recurrent HE admitted between June 2014 and September 2015.

Comparison between home and hospital set-up for unattended home-based polysomnography: a prospective randomized study.

Background: Unattended home-based polysomnography (H-PSG) is a reliable tool for the diagnosis of obstructive sleep apnoea (OSA). The quality of the recording can be influenced by several factors including the set-up location - at home versus in the sleep laboratory. Previous studies have suggested that the failure rate is higher when H-PSG is fitted in hospital.

Real-time attended home-polysomnography with telematic data transmission.

Purpose: Home-polysomnography (HPSG) has been proposed as a cost-effective alternative for obstructive sleep apnea (OSA) diagnosis. We assessed, in a feasibility study, whether telematic transmission using the Dream® and Sleepbox® technologies was associated with low HPSG failure rate.

Methods: Patients referred by chest physicians for clinical suspicion of OSA underwent one HPSG, using Dream® and Sleepbox® (Medatec, Belgium), which is a wireless system able to communicate with Dream®, and with Internet through a wi-fi/3G interface.

Detection of bed-exit events using a new wireless bed monitoring assistance.

Objectives: To assess, using complete polysomnography as the gold standard, the capability of Heasys(®), an innovative wireless bed monitoring assistance to record body movements and presence and to infer bed-exit events and body position changes at night.

Design: Descriptive study.

Settings: Sleep laboratory for patient's recording and home for healthy volunteers.

Sleep efficiency during sleep studies: results of a prospective study comparing home-based and in-hospital polysomnography.

To date, the clinical use of unattended home-based polysomnography (PSG) is not recommended. To assess whether sleep efficiency is better at home, we have performed a prospective, crossover, single-blind study comparing unattended home- versus attended in-hospital PSG in a population referred for high clinical suspicion of obstructive sleep apnoea syndrome (OSA). Within 2 weeks, all the patients underwent both PSG performed by the same sleep technician, which were analysed by another blinded technician.
