Abstract Objectives: The Pupillographic Sleepiness Test (PST) measures the level of alertness based on spontaneous oscillations in pupillary size. Reference data are available for male and female adults within age range 20–60 years. aim present multicenter study was to extend reference from 20 79 Methods: A total 239 healthy subjects, selected three different centers (Berlin, Regensburg, Vienna), were administered PST. Data analyzed with respect possible effects age, gender, time day unrest...
Abstract Long-term monitoring of respiratory rate (RR) is an important component in the management chronic diseases (CRDs). Specifically, predicting acute exacerbations obstructive pulmonary disease (AECOPD) significant scientific and clinical interest. This study aimed to evaluate long-term validity a novel contactless sleep monitor (CSM) home environment CRD patients receiving ventilatory support. Additionally, we assessed patient acceptance, device usability, RR fluctuations associated...
Abstract Purpose The cardiorespiratory polysomnography (PSG) is an expensive and limited resource. Sleepiz One + a novel radar-based contactless monitoring device that can be used e.g. for longitudinal detection of nocturnal respiratory events. present study aimed to compare the performance PSG regarding accuracy apnea–hypopnea index (AHI). Methods From January December 2021, total 141 adult volunteers who were either suspected having sleep apnea or healthy sleepers took part in study. This...
Abstract A new head exposure system for double‐blind provocation studies investigating possible effects of terrestrial trunked radio (TETRA)‐like (385 MHz) on central nervous processes was developed and dosimetrically analyzed. The allows localized in the temporal brain, similar to case operating a TETRA handset at ear. antenna concept enables during wake sleep states while an electroencephalogram (EEG) is recorded. dosimetric assessment uncertainty analysis yield high efficiency 14 W/kg per...
An experimental investigation of warming and warmth perception caused by handset EMF exposure was performed in order to examine its possible impact on blinding. Healthy male participants (15) were exposed three different conditions: sham Terrestrial Trunked Radio (TETRA) handsets with maximum 10 g averaged SAR values 1.5 6 W/kg each days. The study followed a randomized, double‐blind design. TETRA signals simulated from handheld device consisting 385 MHz carrier modulated pulse length 14.17...
Studies have reported that exposure to radiofrequency electromagnetic fields (RF-EMF) emitted by mobile telephony might affect specific sleep features. Possible effects of RF-EMF Wi-Fi networks on sleep-dependent memory consolidation processes not been investigated so far. The present study explored the impact an all-night (2.45 GHz) and its associated physiological correlates. Thirty young males (mean ± standard deviation [SD]: 24.1 2.9 years) participated in this double-blind, randomized,...
Abstract In this pilot study, the authors investigated preliminary effectiveness of digital lifestyle intervention, actensio (mementor DE GmbH), in treating arterial hypertension. Adults with hypertension were randomly assigned to an intervention group (actensio + standard care) or a control (waiting list 1:1 ratio. Primary and secondary endpoints assessed at baseline (t0) 3 months post‐randomization (t1). The primary endpoint was average systolic blood pressure, measured home for 1 week....
Purpose:The quantitative sleep EEG has been considered as electroencephalographic "fingerprint", ie, it is stable within but differs between individuals.So far, however, almost all studies addressing this aspect have conducted in young men.It was therefore of interest to know whether the fingerprint concept holds true older samples both sexes.Patients and Methods: Data from three different subsamples 30 healthy individuals each were reused for present secondary analysis (young men (YM) =...
Purpose: Quantification of nocturnal EEG activity has emerged as a promising extension to the conventional sleep evaluation approach.To date, studies focusing on quantitative data in relation age and sex have revealed considerable variation across lifespan differences between men women.However, power values from elderly individuals are still rare.The present secondary analysis aimed fill this gap.Participants Methods: Sleep 30 healthy males (mean ± SD: 69.1 5.5 years), females (67.8 5.7...
A new head exposure system for double‐blind provocation studies investigating possible effects of 2.45 GHz Wi‐Fi on human sleep was developed and dosimetrically analyzed. The includes six simultaneously radiating directional antennas arranged along a circle (radius 0.6 m) around the test subject's head, enables virtually uniform exposure, i.e. without any preferred direction incidence, during sleep. is fully computer‐controlled applies real wireless local area network (WLAN) signal...
