“…In the meantime, video-based analyses were performed to assess sleep quality, either visually, where video was used as a support for actigraphy measurement validation (So et al, 2005;Sung et al, 2009) or to evaluate the influence of light exposure on the sleep (Kaneshi et al, 2016), or semi-automatically, to detect the eye state in different sleep stages (Porée et al, 2015).…”

Objective: Video and sound acquisition and processing technologies have seen great improvements in recent decades, with many applications in the biomedical area. The aim of this paper is to review the overall state of the art of advances within these topics in paediatrics and to evaluate their potential application for monitoring in the neonatal intensive care unit (NICU). Approach: For this purpose, more than 150 papers dealing with video and audio processing were reviewed. For both topics, clinical applications are described according to the considered cohorts—full-term newborns, infants and toddlers or preterm newborns. Then, processing methods are presented, in terms of data acquisition, feature extraction and characterization. Main results: The paper first focuses on the exploitation of video recordings; these began to be automatically processed in the 2000s and we show that they have mainly been used to characterize infant motion. Other applications, including respiration and heart rate estimation and facial analysis, are also presented. Audio processing is then reviewed, with a focus on the analysis of crying. The first studies in this field focused on induced-pain cries and the newest ones deal with spontaneous cries; the analyses are mainly based on frequency features. Then, some papers dealing with non-cry signals are also discussed. Significance: Finally, we show that even if recent improvements in digital video and signal processing allow for increased automation of processing, the context of the NICU makes a fully automated analysis of long recordings problematic. A few proposals for overcoming some of the limitations are given.

“…The circadian rhythm is of considerable interest because of its potential effects on tissue growth and development ( Kaneshi et al., 2016 ). Circadian rhythm is an endogenous rhythm that allows organisms to adapt to the light-dark cycle, temperature changes, and other environmental factors, and it plays critical roles in many physiological and behavioral processes in mammals ( Bailey et al., 2014 , Bell-Pedersen et al., 2005 ).…”

BMAL1 Deficiency Contributes to Mandibular Dysplasia by Upregulating MMP3

et al. 2018

SummarySkeletal mandibular hypoplasia (SMH), one of the common types of craniofacial deformities, seriously affects appearance, chewing, pronunciation, and breathing. Moreover, SMH is prone to inducing obstructive sleep apnea syndrome. We found that brain and muscle ARNT-like 1 (BMAL1), the core component of the molecular circadian oscillator, was significantly decreased in mandibles of juvenile SMH patients. Accordingly, SMH was observed in circadian-rhythm-disrupted or BMAL1-deficient mice. RNA sequencing and protein chip analyses suggested that matrix metallopeptidase 3 (MMP3) is the potential target of BMAL1. Interestingly, in juvenile SMH patients, we observed that MMP3 was obviously increased. Consistently, MMP3 was upregulated during the whole growth period of 3–10 weeks in Bmal1−/− mice. Given these findings, we set out to characterize the underlying mechanism and found BMAL1 deficiency enhanced Mmp3 transcription through activating p65 phosphorylation. Together, our results provide insight into the mechanism by which BMAL1 is implicated in the pathogenesis of SMH.

“…[28] Previous studies have demonstrated that a light dark cycle has promoted better sleep development than constant light or constant darkness. [11] Published by Sciedu Press According to respiratory response (ventilated baby), the study illustrated that there was a significant difference between control and study group (covered eyes), more than half of ventilated babies were actively breathes against ventilator or coughs regularly in the control group and half of them were spontaneous respiration on ventilator in coved eyes group. Sleep disruption is stressful to sick newborn infants in NICU and alter state regulation and physiological stability.…”

“…[10] Newborn infants have essential needs rest at night and activity during day. [11] According to Roy's adaptation model, nurses should avoid stress factors by controlling light in the NICU that may help newborn infants to adapt with their environment. [1,2,[12][13][14] Nightingale's theory stated that cycled light environment is light in the day and the darkness at night that creates a day/night rhythm that supports human life.…”

Background and aim: The Neonatal Intensive Care Unit (NICU) is a stressful environment for high risk neonates. Persistent bright light is one of the main environmental stressors that are distressed newborn infants in NICU. Cycled lighting may decrease distress level of newborn infants by enhancing calming status. This study aimed to investigate effects of eye cover among high risk neonates at night shift on their distress levels.Methods: Quasi experimental research design was carried out on a randomized sample of 60 newborn infants attending the NICU of El Manial University Hospital (Kasr Al Ainy), (30 control group and 30 study group). Neonatal assessment tool and COMFORTneoNRS scale were utilized for data collection.Results: There was a statistically significant difference between control and study groups regarding the distress levels (p < .00). The mean score of distress levels were 6.80 ± 1.80 and 0.80 ± 1.15 respectively and the mean score of comfort levels in the newborn infants in the control and study groups were 23.22 ± 5.50 and 6.60 ± 1.06 respectively. Eye coved enhanced quite sleep (66.7%), relaxed muscle (73.3%), decrease movement (66.7%) and no crying (85.7%).Conclusions: The use of eye cover among high risk neonates at night shift is effective to decrease their distress level and improve their comfort state in the morning shift by promoting quite sleep and relaxation. Recommendations: The educational program is needed to raise awareness among neonatal nurses about the effect of light reduction methods such as eye patches on the distress level and comfort state that enhances the growth and development of newborn infants.
