“…Its main manifestation is that respiratory airflow drops or even disappears frequently during sleep, which leads to intermittent hypoxemia and wakefulness and excessive sleepiness during the day. Long-term OSAHS induces a series of chronic diseases, such as hypertension, coronary heart disease, arrhythmia, stroke, diabetic insulin resistance, and an increased incidence of traffic accidents [19]. The microsensor array attached to the SleepMatrix converts the deformation signals caused by the relaxation and contraction of the thorax during the breathing process into electrical signals.…”

Sleep quality and duration are critical indicators of individual health. Traditional methods of monitoring them either were limited to the application environment or resulted in discomfort. To overcome these existing limitations, we propose a noncontact sleep monitoring system placed under the mattress, named SleepMatrix, to provide users with a comprehensive picture of their real-time to long-term health status. SleepMatrix is a sleep monitoring system that consists of two parts: a front-end sensor array and a cloud-edge data processing system. The data-driven system, based on the Internet of Things, can be flexibly deployed in environments from homes to transportation, and a variety of centralized control and monitoring functions can be flexibly deployed under different application scenarios. At the same time, users can view real-time and historical data through supporting applications and understand the sleep monitoring results. SleepMatrix is a complete and systematic sleep monitoring tool that can help people understand their health status and its evolution from a new perspective and therefore may contribute greatly to informing users of potential illnesses.INDEX TERMS SleepMatrix , sleep monitoring, sleep stage, the Internet of Things, flexible deployment.

Introduction Abnormal findings on optical coherence tomography (OCT) and electroretinography (ERG) have been reported in participants with schizophrenia spectrum disorders (SSDs). This study aims to reveal the pooled standard mean difference (SMD) in retinal parameters on OCT and ERG among participants with SSDs and healthy controls and their association with demographic characteristics, clinical symptoms, smoking, diabetes mellitus, and hypertension. Methods Using PubMed, Scopus, Web of Science, and PSYNDEX, we searched the literature from inception to March 31, 2023, using specific search terms. This study was registered with PROSPERO (CRD4202235795) and conducted according to PRISMA 2020. Results We included 65 studies in the systematic review and 44 in the meta-analysis. Participants with SSDs showed thinning of the peripapillary retinal nerve fiber layer (pRNFL), macular ganglion cell layer- inner plexiform cell layer, and retinal thickness in all other segments of the macula. A meta-analysis of studies that excluded SSD participants with diabetes and hypertension showed no change in results, except for pRNFL inferior and nasal thickness. Furthermore, a significant difference was found in the pooled SMD of pRNFL temporal thickness between the left and right eyes. Meta-regression analysis revealed an association between retinal thinning and duration of illness, positive and negative symptoms. In OCT angiography, no differences were found in the foveal avascular zone and superficial layer foveal vessel density between SSD participants and controls. In flash ERG, the meta-analysis showed reduced amplitude of both a- and b-waves under photopic and scotopic conditions in SSD participants. Furthermore, the latency of photopic a-wave was significantly shorter in SSD participants in comparison with HCs. Discussion Considering the prior report of retinal thinning in unaffected first-degree relatives and the results of the meta-analysis, the findings suggest that retinal changes in SSDs have both trait and state aspects. Future longitudinal multimodal retinal imaging studies are needed to clarify the pathophysiological mechanisms of these changes and to clarify their utility in individual patient monitoring efforts.
