Abstract
BACKGROUND AND OBJECTIVE Although quiet time is implemented in neonatal intensive care units (NICUs) for the benefit of infants, it may also positively impact the psychological outcomes of healthcare professionals. Several studies have examined the impact of quiet-time implementation on patients; however, there is a paucity of research assessing its impact on the psychological outcomes of NICU nurses, particularly in Saudi Arabia. OBJECTIVE AND METHODS This study aimed to assess the impact of quiet time on the psychological outcomes (stress, anxiety, and depression) of NICU nurses in Jeddah, Saudi Arabia. A cross-sectional design was used for this study. A total of 87 NICU nurses from two hospitals participated in this study. One group did not practice quiet time, while the second group did. A questionnaire survey assessed participants' demographic characteristics, and their depression, anxiety, and stress were assessed using the depression, anxiety, and stress scale-21 (DASS-21). The data were analyzed for frequency, percentage, mean, and standard deviation (SD). Bivariate analysis, independent t-tests, and one-way analysis of variance were used to test the differences between variables and groups. Pearson's correlation coefficient (r) was used to analyze the relationships between continuous variables and perceived stress, anxiety, and depression. RESULTS A substantial number of NICU nurses perceived stress, anxiety, and depression; however, there were no significant differences in perceived stress, anxiety, and depression between the nurses who worked in NICUs that applied quiet time and NICUs that did not (P ≤ 0.05). CONCLUSION This study found no statistically significant relationship between quiet-time implementation and perceived stress, anxiety, or depression among NICU nurses. Further research with a larger sample size or increased quiet-time implementation may be required.

Abstract
AIM Noise levels above 45 dB in a neonatal intensive care unit (NICU) and 60 dB during neonatal transport are recognised hazards, but protective equipment is not standard. We measured noise levels in both settings, with and without noise protection. METHODS Peak sound and equivalent continuous sound levels were measured in a NICU and during road transport, at a mannequin's ear and inside and outside the incubator. Recordings were made without protective earwear, with noise protecting earmuffs and with active noise cancelling headphones. RESULTS In the NICU, the peak levels at the ear, and inside and outside the incubator, were 61, 68 and 76 dB. The equivalent continuous sound levels were 45, 54 and 59 dB. During road transport, the respective levels were 70, 77 and 83 dB and 54, 62 and 68 dB. In the NICU, 80% of environmental peak noise reached the ear and this was reduced to 78% with earmuffs and 75% with active noise cancelling. The respective figures during transport were 87% without protection and 72% with active noise cancelling, with an unexpected increase for ear muffs. CONCLUSION Noise levels exceeded safe limits in the NICU and during transport, but active noise cancelling reduced exposure.

Abstract
Prematurity is becoming a real public health issue as more and more children are being born prematurely, alongside a higher prevalence of neurodevelopmental disorders. Early intervention programs in Neonatal Intensive Care Units (NICUs) correspond to these uni- or multi-sensorial solicitations aiming to prevent and detect complications in order to support the development of preterm infants. This article aims to distinguish sensory intervention programs according to the gradient of the type of solicitations, uni- or multi-modal, and according to the function of the person who performs these interventions. Uni-sensorial interventions are essentially based on proprioceptive, gustatory, or odorant solicitations. They allow, in particular, a reduction of apneas that support the vegetative states of the preterm infant. On the other hand, the benefits of multi-sensory interventions seem to have a longer-term impact. Most of them allow the support of the transition from passive to active feeding, an increase in weight, and the improvement of sleep-wake cycles. These solicitations are often practiced by caregivers, but the intervention of parents appears optimal since they are the main co-regulators of their preterm child's needs. Thus, it is necessary to co-construct and train the parents in this neonatal care.

Abstract
BACKGROUND Preterm delivery is a stressful event and stress can affect adaptation to maternal role. The purpose of this study is to determine the effect of supportive-educational interventions on stress and adaptation to the maternal role among women with premature infants hospitalized in the neonatal intensive care unit. METHODS This quasi-experimental study was conducted on 60 women with premature infants hospitalized in the neonatal intensive care unit. A control group (n = 30) was initially selected from eligible female participants. Sampling was stopped for three weeks and then the intervention group was sampled. The entire sampling process was carried out from December 2018 to June 2019. The control group received usual care at the hospital and the intervention group (n = 30) received three sessions of supportive-educational intervention in addition to routine care. Data were collected through the perceived stress and the maternal role adaptation questionnaires completed by both groups at the time of infant discharge, and also at the follow-up period (one month after discharge). RESULTS The results showed that maternal stress score changed considerably over time and a significant difference between the two groups was observed (P < 0.05). Additionally, adaptation to the maternal role changed substantially over time and the difference between the two groups was statistically significant (P < 0.05). CONCLUSION The supportive-educational program reduced the stress of mothers with premature infants hospitalized in the neonatal intensive care unit and increased their adaptation to the maternal role.

Abstract
OBJECTIVE To compare light and sound levels before and after a change of design and evaluate these levels considering recommended NICU standards. STUDY DESIGN A pre-test/post-test design. Light and sound levels were compared between the former open ward (OW) NICU of 34 beds and the current 40-bed unit composed of both pods and single-family rooms (SFR). RESULT Light levels were significantly higher in the pod/SFR unit for all levels of care, days of the week and time of the day. These findings could be attributed to the number and configuration of windows in the new pod/SFR unit allowing for more daylight entry compared to the OW. Sound levels were significantly lower in the current NICU (pod/SFR) compared to the former OW. CONCLUSION Following the change of design, the pod/SFR unit are less noisy than the OW, although light levels are higher indicating the necessity to measure light levels.

Effectiveness of interventions on early neurodevelopment of preterm infants: a systematic review and meta-analysis. BMC Pediatr 2021; 21:210.

Abstract
BACKGROUND As preterm infants' neurodevelopment is shaped by NICU-related factors during their hospitalization, it is essential to evaluate which interventions are more beneficial for their neurodevelopment at this specific time. The objective of this systematic review and meta-analysis was to evaluate the effectiveness of interventions initiated during NICU hospitalization on preterm infants' early neurodevelopment during their hospitalization and up to two weeks corrected age (CA). METHODS This systematic review referred to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses [PRISMA] guidelines and was registered in PROSPERO (CRD42017047072). We searched CINAHL, MEDLINE, PubMed, EMBASE (OVID), Cochrane Systematic Reviews, CENTRAL, and Web of Science from 2002 to February 2020 and included randomized controlled/clinical trials conducted with preterm infants born between 24 and 366/7 weeks of gestation. All types of interventions instigated during NICU hospitalization were included. Two independent reviewers performed the study selection, data extraction, assessment of risks of bias and quality of evidence. RESULTS Findings of 12 studies involving 901 preterm infants were synthesized. We combined three studies in a meta-analysis showing that compared to standard care, the NIDCAP intervention is effective in improving preterm infants' neurobehavioral and neurological development at two weeks CA. We also combined two other studies in a meta-analysis indicating that parental participation did not significantly improve preterm infants' neurobehavioral development during NICU hospitalization. For all other interventions (i.e., developmental care, sensory stimulation, music and physical therapy), the synthesis of results shows that compared to standard care or other types of comparators, the effectiveness was either controversial or partially effective. CONCLUSIONS The overall quality of evidence was rated low to very low. Future studies are needed to identify interventions that are the most effective in promoting preterm infants' early neurodevelopment during NICU hospitalization or close to term age. Interventions should be appropriately designed to allow comparison with previous studies and a combination of different instruments could provide a more global assessment of preterm infants' neurodevelopment and thus allow for comparisons across studies.

Abstract
In this study, we observed physiological reactions of premature infants during sponge bathing in the neonatal intensive care unit (NICU). The infants’ body temperature, heart rate, and oxygen saturation were monitored to examine hypothermia risks during bathing. The participants of the study were 32 premature infants who were hospitalized right after their birth in the V hospital in Korea between December 2012 and August 2013. The informed consents of the study were received from the infants’ parents. The infants were randomly assigned into two-day and four-day bath cycle groups and their physiological reactions were monitored before bathing as well as 5 and 10 min after bathing. The collected data were analyzed using the SPSS statistical package through t-test. A significant drop in body temperature was noted in both groups; that is, 4-day bathing cycle and 2-day bathing cycle (p < 0.001). However, there were no significant changes in heart rate or transcutaneous oxygen levels. There was no significant change between groups at each measurement point. In order to minimize the physiological instability that may be caused during bathing, the care providers should try to complete bathing within the shortest possible time and to make bathing a pleasant and useful stimulus for infants.

Family nurture intervention in the NICU increases autonomic regulation in mothers and children at 4-5 years of age: Follow-up results from a randomized controlled trial. PLoS One 2020; 15:e0236930.

Abstract
Background Maturation of multiple neurobehavioral systems, including autonomic regulation, is altered by preterm birth. The purpose of this study was to determine the long-term effects of Family Nurture Intervention (FNI) in the NICU on autonomic regulation of preterm infants and their mothers. Method A subset of infants and mothers (48% of infants, 51% of mothers) randomly assigned to either standard are (SC), or SC plus the FNI in the NICU in a prior RCT (ClincalTrials.gov; NCT01439269) returned for follow-up assessments when the children were 4 to 5 years corrected age (CA). ECGs were collected for 10 minutes in mothers and their children while children were in their mothers’ laps. Heart rate, standard deviation for heart rate, respiratory sinus arrhythmia (RSA)–an index of parasympathetic regulation, and a measure of vagal efficiency were quantified. Results Both children and mothers in the FNI group had significantly greater levels of RSA compared to the SC group (child: mean difference = 0.60, 95% CI 0.17 to 1.03, p = 0.008; mother: mean difference = 0.64, 95% CI 0.07 to 1.21, p = 0.031). In addition, RSA increased more rapidly in FNI children between infancy and the 4 to 5-year follow-up time point (SC = +3.11±0.16 loge msec2, +3.67±0.19 loge msec2 for FNI, p<0.05). These results show that the rate of increase in RSA from infancy to childhood is more rapid in FNI subjects. Conclusion Although these preliminary follow-up results are based on approximately half of subjects originally enrolled in the RCT, they suggest that FNI-NICU led to healthier autonomic regulation in both mother and child, when measured during a brief face-to-face socioemotional interaction. A Pavlovian autonomic co-conditioning mechanism may underly these findings that can be exploited therapeutically.

Abstract
Objective Noise in the neonatal intensive care unit can be detrimental to the health of the hospitalized infant. Means of reducing that noise include staff training, warning lights, and ear coverings, all of which have had limited success. Single family rooms, while an improvement, also expose the hospitalized infant to the same device alarms and mechanical noises found in open bay units. Methods We evaluated a non-contact incubator-based active noise control device (Neoasis™, Invictus Medical, San Antonio, Texas) in a simulated neonatal intensive care unit (NICU) setting to determine whether it could effectively reduce the noise exposure of infants within an incubator. In the NICU simulation center, we generated a series of clinically appropriate sound sequences with bedside medical devices such as a patient monitor and fluid infusion devices, hospital air handling systems, and device mechanical sounds. A microphone-equipped infant mannequin was oriented within an incubator. Measurements were made with the microphones with the Neoasis™ deactivated and activated. Results The active noise control device decreased sound pressure levels for certain alarm sounds by as much as 14.4 dB (a 5.2-fold reduction in sound pressure) at the alarm tone’s primary frequency. Frequencies below the 2 kHz octave band were more effectively attenuated than frequencies at or above the 2 kHz octave band. Background noise levels below 40 dBA were essentially not impacted by the active noise control device. Conclusions The active noise control device further reduces noise inside infant incubators. Device safety and potential health benefits of the quieter environment should be verified in a clinical setting.

Abstract
Background: The intrauterine hearing experience differs from the extrauterine hearing exposure within a neonatal intensive care unit (NICU) setting. Also, the listening experience of a neonate drastically differs from that of an adult. Several studies have documented that the sound level within a NICU exceeds the recommended threshold by far, possibly related to hearing loss thereafter. The aim of this study was, first, to precisely define the dynamics of sounds within an incubator and, second, to give clinicians and caregivers an idea about what can be heard “inside the box.” Methods: Audio recordings within an incubator were conducted at the Pediatric Simulation Center of the Medical University Vienna. They contained recorded music, speech, and synthesized sounds. To understand the dynamics of sounds around and within the incubator, the following stimuli were used: broadband noise with decreasing sound level in 10 steps of 6 dB, sine waves (62.5, 125, 250, 500, 1000, 2000, 4000, 8000, and 16,000 Hz), logarithmic sweep (Chirp) over the frequency band 20 Hz to 21 kHz, singing male voice, singing, and whispering female voice. Results: Our results confirm a protective effect of the incubator from noises above 500 Hz in conditions of “no-flow” and show almost no protective effect of an incubator cover. We, furthermore, observed a strong boost of low frequencies below 125 Hz within the incubator, as well as a notable increase of higher frequency noises with open access doors, a significant resonant effect of the incubator, and a considerable masking effect of the respiratory support against any other source of noise or sound stimulation even for “low-flow” conditions. Conclusion: Our study reveals high noise levels of air supply at high flow rates and the boost of low frequencies within the incubator. Education of medical staff and family members as well as modifications of the physical environment should aim at reducing noise exposure of preterm infants in the incubator. Audiovisual material is provided as Supplementary Material.

Abstract
Noise may cause stress responses such as apnea, hypoxemia, changes in oxygen saturation and augmented oxygen consumption secondary to elevated heart and respiratory rates. Moreover, stress results in increased intracranial pressure, abnormal sleep patterns, hearing impairment, and bronchopulmonary dysplasia, retinopathy of prematurity, intraventricular hemorrhage, periventricular leukomalacia, retardate development and alterations in the neuroendocrine system. Herein, this study aimed to discuss the effects of earmuffs on physiological parameters in preterm infants. The relevant and available peer-reviewed publications from 2012 to 2018 from various databases were analyzed. For the assessment of the studies, the full-text accessible studies were included for analysis. The retrieved documents were analyzed using VOSviewer regarding the geographical distributions of the documents with their numbers and citations, keywords proposed by the researchers. All records with the term "earmuffs OR earmuff" in the "article title, abstract, keywords" were retrieved from different databases. Accordingly, 396 documents containing the word "earmuffs OR earmuff" were recorded. The search was then restricted for publications that contain the words "noise AND nursing AND preterm" in the title and abstracts (TITLE-ABS-KEY (earmuffs OR earmuff)) AND (noise AND nursing AND preterm) (Scopus=390; Web of Science=1, Medline=2; Cochrane=1; Embase=1= Pubmed=1=n=396). After inclusion and exclusion criteria, 7 documents were recorded and then evaluated for the present study. As a conclusion, the effects of earmuffs on physiological parameters of preterm infants have not been clearly understood and reported yet. Along with the present documents, it is not clear that the use of earmuffs reduces stress and provides physiological stability in preterm infants born between approximately 28-32 weeks. The studies with a larger sample size are needed for validation of information reported in the articles analyzed herein.

Abstract
Prematurity is associated with an increased risk of long-term health and neurodevelopmental problems. Key perinatal and neonatal factors that affect these outcomes have long been studied. However, more recently, there has been an appreciation of the importance of environmental factors in long-term outcomes of preterm babies, particularly in light of the rapid maturation of the brain during these babies' early days of life. Breastmilk and breastfeeding is the gold standard for infant feeding, including preterm babies. The benefits are well established in regard to protection from serious complications like necrotising enterocolitis. Although theoretically plausible, the benefits for neurodevelopment are less clear. Noise, pain and the environment of the neonatal intensive care can also affect infant neurodevelopment. It is established that noise and pain have deleterious effects. However, the benefits of single-room vs open-bay neonatal units remain under debate. Developmental care practices, of which there are many, are increasingly embraced worldwide. There are benefits both for the parents and the baby, however, the evidence is difficult to pool due to the heterogeneity of studies and study populations. Finally, it is important to remember the importance of the role of parents in shaping long-term neurodevelopment of the high-risk preterm newborn. Increasingly, positive parenting and parents' mental health are shown to have long lasting advantages for preterm infants. A deeper understanding of early environmental factors is key to developing future interventions to optimise outcomes of preterm newborns.

Abstract
Introduction: Low birth weight (LBW) infants who have been hospitalized are exposed to various conditions that provoke discomfort, which could trigger a stress response and growth disorders. This study aimed to identify the effects of auditory stimuli from Murottal Quran when it comes to the comfort and weight of LBW infants.Methods: This study used a clinical randomized controlled trial design involving 52 low birth weight infants. The infants were randomly assigned to either the intervention group (n=26) or the control (n=26). The intervention of Murottal Quran was given using a speaker 4 times a day for 20 minutes every 3 hours. This intervention was conducted for three days.Results: The results of this study show that there is a significant difference in the comfort of low birth weight infants after Murottal Qur’an on the first, second, and third days between the intervention and control groups (p=0.014; <0.001; <0.001). There was no significant difference in the weight between the intervention and control groups in the first, second, and third days (p=0.481; 0.481; 0.464).Conclusion: The auditory stimuli of Murottal Quran can help to improve the comfort level of low birth weight infants during hospitalization. It can therefore be used as a supportive therapy to facilitate low birth weight infant and premature infant development.

Abstract
Brain injury remains one of the major unsolved problems in neonatal care, with survivors at high risk of lifelong neurodisability. It is unlikely that a single intervention can ameliorate neonatal brain injury, given the complex interaction between pathological processes, developmental trajectory, genetic susceptibility, and environmental influences. However, a coordinated, interdisciplinary approach to understand the root cause enables early detection, and diagnosis with enhanced clinical care offering the best chance of improving outcomes and facilitate new lines of neuroprotective treatments. Adult neurointensive care has existed as a speciality in its own right for over 20 years; however, it is only recently that large prospective studies have demonstrated the benefit of this model of care. The 'Neuro-intensive Care Nursery' model originated at the University of California San Francisco in 2008, and since then a growing number of units worldwide have adopted this approach. As well as providing consistent coordinated care for infants from a multidisciplinary team, it provides opportunities for specialist education and training in neonatal neurology, neuromonitoring, neuroimaging and nursing. This review outlines the origins of brain-oriented care of the neonate and the development of the Neuro-NICU (neonatal intensive care unit) and discusses some of the challenges and opportunities in expanding this model of care.

Abstract
INTRODUCTION Choice of appropriate nutrition has a special place, which variations in dietary nutrient can potentially be involved in growth deficits in preterm neonates. AIM to investigate the effect of protein supplementation in very low birth weight (VLBW= birth weight under 1500 grams) infants on neurological growth in the third year of birth. MATERIAL AND METHODS We investigated neurological growth in two groups of control and intervention (each group, n= 18 subjects). The intervention group includes 3-year-old children who weighting less than 1200 grams at birth and have received protein supplementation at the course of NICU hospitalization, protein was added to maternal milk when the amount of milk reaches to 100 cc/kg/day, at this time parenteral nutrition was discontinued and the volume of feeding was increased 20cc/kg/day until reached to 150-180cc/kg/day. We also added the fortifier to breast milk at this time (FMS- Aptamil- DANON). The fortification and the protein supplementation were stopped when the weight of the baby reached to 1500 grams. The control group was fed similar to the intervention group, without protein supplemental intake. Neurodevelopmental outcomes were evaluated using ASQ, NEWSHA and BINS tools. RESULTS There was no significant difference between the mean head circumference in the two groups (p=0.209). There was no significant relationship between neurological growth rate evaluated by BINS tool in two groups (p=0.266). There was a significant correlation between the neurological development assessed by the ASQ tool in the areas of communication (p=0.014) and gross motor (p=0.001) in the two groups, however, no significant relationship was found in terms of fine motor (p=0.63), problem solving (p=0.07) and personal-social relationships in both groups (p=0.152). There was a significant correlation between neurological development evaluated using the NEWSHA tool in terms of auditory (p=0.031), verbal language (p=0.024), cognitive (p=0.007), social connection (p=0.034) and motor (p=0.002) in the two groups. CONCLUSION Protein intake in preterm infants didn't reveal long term effects on the growth of head circumference. Moreover, it was capable of improving neurological growth in the areas of communication and gross motor (based on the ASQ) and auditory, verbal language, cognitive, social connection, and motor (based on the NEWSHA).

Abstract
The progress that has been made in neonatology is associated with an increasing number of painful procedures constantly being performed on the neonate. Additionally, prolonged hospitalization of premature neonates in NICUs isolates the family from their child. Parents may state that they do not have any parental feelings and cannot communicate with their newborns. The FCC (Family-Centered Care) initiative responded to emerging reports about the adverse consequences ensuing from the lack of parental access to hospitalized children. The FCC should be understood as care based on partner relations between families and health professionals, which is supposed to lead to health and well-being for both the children and their parents. The FCC should become standard practice in all neonatal intensive care units.

Abstract
BACKGROUND Cerebral palsy is an umbrella term that encompasses disorders of movement and posture attributed to non-progressive disturbances occurring in the developing foetal or infant brain. As there are diverse risk factors and aetiologies, no one strategy will prevent cerebral palsy. Therefore, there is a need to systematically consider all potentially relevant interventions for prevention. OBJECTIVES PrimaryTo summarise the evidence from Cochrane Systematic Reviews regarding effects of neonatal interventions for preventing cerebral palsy (reducing cerebral palsy risk).SecondaryTo summarise the evidence from Cochrane Systematic Reviews regarding effects of neonatal interventions that may increase cerebral palsy risk. METHODS We searched the Cochrane Database of Systematic Reviews (27 November 2016) for reviews of neonatal interventions reporting on cerebral palsy. Two review authors assessed reviews for inclusion, extracted data, and assessed review quality (using AMSTAR and ROBIS) and quality of the evidence (using the GRADE approach). Reviews were organised by topic; findings were summarised in text and were tabulated. Interventions were categorised as effective (high-quality evidence of effectiveness); possibly effective (moderate-quality evidence of effectiveness); ineffective (high-quality evidence of harm); probably ineffective (moderate-quality evidence of harm or lack of effectiveness); and no conclusions possible (low- to very low-quality evidence). MAIN RESULTS Forty-three Cochrane Reviews were included. A further 102 reviews pre-specified the outcome cerebral palsy, but none of the included randomised controlled trials (RCTs) reported this outcome. Included reviews were generally of high quality and had low risk of bias, as determined by AMSTAR and ROBIS. These reviews involved 454 RCTs; data for cerebral palsy were available from 96 (21%) RCTs involving 15,885 children. Review authors considered interventions for neonates with perinatal asphyxia or with evidence of neonatal encephalopathy (3); interventions for neonates born preterm and/or at low or very low birthweight (33); and interventions for other specific groups of 'at risk' neonates (7). Quality of evidence (GRADE) ranged from very low to high.Interventions for neonates with perinatal asphyxia or with evidence of neonatal encephalopathyEffective interventions: high-quality evidence of effectivenessResearchers found a reduction in cerebral palsy following therapeutic hypothermia versus standard care for newborns with hypoxic ischaemic encephalopathy (risk ratio (RR) 0.66, 95% confidence interval (CI) 0.54 to 0.82; seven trials; 881 children).No conclusions possible: very low-quality evidenceOne review observed no clear differences in cerebral palsy following therapeutic hypothermia versus standard care.Interventions for neonates born preterm and/or at low or very low birthweightPossibly effective interventions: moderate-quality evidence of effectivenessResearchers found a reduction in cerebral palsy with prophylactic methylxanthines (caffeine) versus placebo for endotracheal extubation in preterm infants (RR 0.54, 95% CI 0.32 to 0.92; one trial; 644 children).Probably ineffective interventions: moderate-quality evidence of harmResearchers reported an increase in cerebral palsy (RR 1.45, 95% CI 1.06 to 1.98; 12 trials; 1452 children) and cerebral palsy in assessed survivors (RR 1.50, 95% CI 1.13 to 2.00; 12 trials; 959 children) following early (at less than eight days of age) postnatal corticosteroids versus placebo or no treatment for preventing chronic lung disease in preterm infants.Probably ineffective interventions: moderate-quality evidence of lack of effectivenessTrial results showed no clear differences in cerebral palsy following ethamsylate versus placebo for prevention of morbidity and mortality in preterm or very low birthweight infants (RR 1.13, 95% CI 0.64 to 2.00; three trials, 532 children); volume expansion versus no treatment (RR 0.76, 95% CI 0.48 to 1.20; one trial; 604 children); gelatin versus fresh frozen plasma (RR 0.94, 95% CI 0.52 to 1.69; one trial, 399 children) for prevention of morbidity and mortality in very preterm infants; prophylactic indomethacin versus placebo for preventing mortality and morbidity in preterm infants (RR 1.04, 95% CI 0.77 to 1.40; four trials; 1372 children); synthetic surfactant versus placebo for respiratory distress syndrome in preterm infants (RR 0.76, 95% CI 0.55 to 1.05; five trials; 1557 children); or prophylactic phototherapy versus standard care (starting phototherapy when serum bilirubin reached a pre-specified level) for preventing jaundice in preterm or low birthweight infants (RR 0.96, 95% CI 0.50 to 1.85; two trials; 756 children).No conclusions possible: low- to very low-quality evidenceNo clear differences in cerebral palsy were observed with interventions assessed in 21 reviews.Interventions for other specific groups of 'at risk' neonatesNo conclusions possible: low- to very low-quality evidenceReview authors observed no clear differences in cerebral palsy with interventions assessed in five reviews. AUTHORS' CONCLUSIONS This overview summarises evidence from Cochrane Systematic Reviews regarding effects of neonatal interventions on cerebral palsy, and can be used by researchers, funding bodies, policy makers, clinicians, and consumers to aid decision-making and evidence translation. To formally assess other benefits and/or harms of included interventions, including impact on risk factors for cerebral palsy, review of the included Reviews is recommended.Therapeutic hypothermia versus standard care for newborns with hypoxic ischaemic encephalopathy can prevent cerebral palsy, and prophylactic methylxanthines (caffeine) versus placebo for endotracheal extubation in preterm infants may reduce cerebral palsy risk. Early (at less than eight days of age) postnatal corticosteroids versus placebo or no treatment for preventing chronic lung disease in preterm infants may increase cerebral palsy risk.Cerebral palsy is rarely identified at birth, has diverse risk factors and aetiologies, and is diagnosed in approximately one in 500 children. To date, only a small proportion of Cochrane Systematic Reviews assessing neonatal interventions have been able to report on this outcome. There is an urgent need for long-term follow-up of RCTs of such interventions addressing risk factors for cerebral palsy (through strategies such as data linkage with registries) and for consideration of the use of relatively new interim assessments (including the General Movements Assessment). Such RCTs must be rigorous in their design and must aim for consistency in cerebral palsy outcome measurement and reporting to facilitate pooling of data and thus to maximise research efforts focused on prevention.

Abstract
Human and animal studies demonstrate that early auditory experiences influence brain development. The findings are particularly crucial following preterm birth as the plasticity of auditory regions, and cortex development are heavily dependent on the quality of auditory stimulation. Brain maturation in preterm infants may be affected among other things by the overwhelming auditory environment of the neonatal intensive care unit (NICU). Conversely, auditory deprivation, (e.g., the lack of the regular intrauterine rhythms of the maternal heartbeat and the maternal voice) may also have an impact on brain maturation. Therefore, a nurturing enrichment of the auditory environment for preterm infants is warranted. Creative music therapy (CMT) addresses these demands by offering infant-directed singing in lullaby-style that is continually adapted to the neonate’s needs. The therapeutic approach is tailored to the individual developmental stage, entrained to the breathing rhythm, and adapted to the subtle expressions of the newborn. Not only the therapist and the neonate but also the parents play a role in CMT. In this article, we describe how to apply music therapy in a neonatal intensive care environment to support very preterm infants and their families. We speculate that the enriched musical experience may promote brain development and we critically discuss the available evidence in support of our assumption.

Abstract
In the NICU, systematic exposure to sound-pressure above the recommended level can affect both neonates and staff. This study aimed to evaluate the sound pressure levels in three Portuguese NICUs and the noise perceptions of staff. The measurements were performed with a sound-level meter, considering the location of the main sources of noise and the layout of the units. A questionnaire was applied to assess noise perceptions of professionals. Among the staff, 41.1% classified the environment (regarding noise) as "slightly uncomfortable"; 48.4% considered it as "acceptable." The majority (55.5%) considered "equipment" the most annoying source of noise. The results showed that noise levels were excessive in all the evaluated areas of the NICUs, exceeding international guidelines, with levels ranging between 48.7 dBA to 71.7 dBA. Overall, there is a need for more research to verify the effectiveness of some actions and strategies to reduce the effect of noise in the NICU.

Abstract
BACKGROUND Previous systematic reviews have examined preterm infants' long-term neurodevelopment after neonatal intensive care unit (NICU) discharge, although none have explored the effectiveness of interventions on preterm infants' neurodevelopment during NICU hospitalization. The aim of this review is to evaluate whether interventions, i.e., sensory stimulation, parental involvement, and control of environment, improve preterm infants' neurodevelopment during their NICU hospitalization. METHODS Experimental studies such as randomized controlled/clinical trials (RCTs) and cluster RCT will be included in this systematic review. Selected studies will be published in English or in French, in the past 15 years from 2002 to 2017. The following electronic databases will be searched to locate relevant studies: CINAHL, MEDLINE, PubMed, EMBASE (OVID), Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science. For all steps in selecting studies, agreement will be reached between two experts in neonatology. Data extraction will be performed independently by the two same experts and will then be compared. The Cochrane assessment tool will be used to screen the studies for risk of bias. A meta-analysis will be performed if the included studies are sufficiently homogeneous. Results will be analyzed using a standardized mean difference (with a 95% confidence interval). Statistical heterogeneity will be evaluated using the χ 2 test at the significance level of 0.1 and the I 2 with the classification suggested by PRISMA-P. If possible, subgroup analyses will be carried out considering preterm infants' gestational age, length of NICU hospitalization, and the characteristics of the intervention such as who delivered it, the type, the dose, the frequency, and the duration. Data synthesis will be performed using the RevMan 5.1 software. Publication bias and selection of variables in publication will be examined using the graphical method of funnel plot and with the statistical test of Egger. Quality of the evidence of all outcomes will be assessed using the Grades of Recommendations Assessment, Development and Evaluation (GRADE) Working Group. DISCUSSION The results of this systematic review will highlight which interventions are effective for promoting preterm infants' neurodevelopment during NICU hospitalization and will contribute to the body of knowledge in neonatal care by providing guidance for NICU clinical practice and research.

Abstract
BACKGROUND Excessive noise in neonatal intensive care units (NICUs) can interfere with infants' growth, development and healing.Local problem:Sound levels in our NICUs exceeded the recommended levels by the World Health Organization. METHODS We implemented a noise reduction strategy in an urban, tertiary academic medical center NICU that included baseline noise measurements. We conducted a survey involving staff and visitors regarding their opinions and perceptions of noise levels in the NICU. Ongoing feedback to staff after each measurement cycle was provided to improve awareness, engagement and adherence with noise reduction strategies. After widespread discussion with active clinician involvement, consensus building and iterative testing, changes were implemented including: lowering of equipment alarm sounds, designated 'quiet times' and implementing a customized education program for staff. INTERVENTIONS A multiphase noise reduction quality improvement (QI) intervention to reduce ambient sound levels in a patient care room in our NICUs by 3 dB (20%) over 18 months. RESULTS The noise in the NICU was reduced by 3 dB from baseline. Mean (s.d.) baseline, phase 2, 3 and 4 noise levels in the two NICUs were: LAeq: 57.0 (0.84), 56.8 (1.6), 55.3 (1.9) and 54.5 (2.6) dB, respectively (P<0.01). Adherence with the planned process measure of 'quiet times' was >90%. CONCLUSIONS Implementing a multipronged QI initiative resulted in significant noise level reduction in two multipod NICUs. It is feasible to reduce noise levels if QI interventions are coupled with active engagement of the clinical staff and following continuous process of improvement methods, measurements and protocols.

Abstract
Introduction: One of the problems that the delivery of continuous positive airway pressure (CPAP) via a helmet poses is the generation of noise. The objective of our study was to assess the effect that the use of filter has on sound pressure levels generated by the delivery of positive airway pressure at different gas flow rates. Materials and Methods: Sound pressure levels generated by neonatal helmet CPAP delivery were measured at different gas flows (20, 30, and 40 l/min) with and without a breathing filter. Noise intensity was measured by installing microphones in the inner ear of dummy heads wearing helmets. Results: The sound pressure level increased by 38% at a gas flow of 40 l/min, as compared to a gas flow of 20 l/min {74 dBA [interquartile range (IQR) 2,2] vs 52 dBA (IQR 5,9), respectively}. Using the breathing filter as a diffuser has a variety of effects on sound pressure levels according to the gas flow rate. Conclusion: The intensity of the noise generated by helmet delivery of positive airway pressure depends on the type of helmet used, gas flow, and use or not of a diffuser filter. Breathing filters with gas flows over 30 l/min might not be recommended since they would not attenuate but will rather amplify sound pressure.

Abstract
General electric devices and ventilation systems are known to generate low frequency noise (LFN) with frequencies of <100 Hz. Previous studies showed that exposure to LFN caused impairments of balance in humans and mice during adulthood. On the other hand, a previous study showed that noise levels in the neonatal intensive care unit (NICU) were greater than those in general home or office environments. Therefore, it is possible that neonates have a potential risk to be exposed to LFN in the NICU. However, the risk of neonatal exposure to LFN remains unclear in humans and mice. In this study, male ICR mice were exposed to LFN at 100 Hz for 4 weeks after birth and then subjected to rotarod and beam crossing tests in order to assess LFN-mediated risk of imbalance during the neonatal period. Exposure to LFN at 70 dB, but not exposure to LFN up to 60 dB, during the neonatal period significantly decreased performance scores for rotarod and beam crossing tests compared to the scores of the control group. The number of calbindin-positive hair cells in the saccule and utricle was decreased in mice exposed to LFN at 70 dB for 4 weeks in the neonatal phase. Cessation of exposure for 10 weeks did not result in recovery of the decreased performance in rotarod and beam crossing tests. Thus, our results suggest that 70 dB is a possible threshold for exposure to LFN for 4 weeks during the neonatal period causing unrecoverable imbalance in mice.

Abstract
UNLABELLED In March 2014, the American Academy of Sleep Medicine (AASM) Board of Directors requested the Scoring Manual Editorial Board develop rules, terminology, and technical specifications for scoring sleep/wake states in full-term infants from birth to 2 mo of age, cognizant of the 1971 Anders, Emde, and Parmelee Manual for Scoring Sleep in Newborns. On July 1, 2015, the AASM published rules for scoring sleep in infants, ages 0-2 mo. This evidence-based review summarizes the background information provided to the Scoring Manual Editorial Board to write these rules. The Anders Manual only provided criteria for coding physiological and behavioral state characteristics in polysomnograms (PSG) of infants, leaving specific sleep scoring criteria to the individual investigator. Other infant scoring criteria have been published, none widely accepted or used. The AASM Scoring Manual infant scoring criteria incorporate modern concepts, digital PSG recording techniques, practicalities, and compromises. Important tenets are: (1) sleep/wake should be scored in 30-sec epochs as either wakefulness (W), rapid eye movement, REM (R), nonrapid eye movement, NREM (N) and transitional (T) sleep; (2) an electroencephalographic (EEG) montage that permits adequate display of young infant EEG is: F3-M2, F4-M1, C3-M2, C4-M1, O1-M2, O2-M1; additionally, recording C3-Cz, Cz-C4 help detect early and asynchronous sleep spindles; (3) sleep onsets are more often R sleep until 2-3 mo postterm; (4) drowsiness is best characterized by visual observation (supplemented by later video review); (5) wide open eyes is the most crucial determinant of W; (6) regularity (or irregularity) of respiration is the single most useful PSG characteristic for scoring sleep stages at this age; (7) trace alternant (TA) is the only relatively distinctive EEG pattern, characteristic of N sleep, and usually disappears by 1 mo postterm replaced by high voltage slow (HVS); (8) sleep spindles first appear 44-48 w conceptional age (CA) and when present prompt scoring N; (9) score EEG activity in an epoch as "continuous" or "discontinuous" for inter-scorer reliability; (10) score R if four or more of the following conditions are present, including irregular respiration and rapid eye movement(s): (a) low chin EMG (for the majority of the epoch); (b) eyes closed with at least one rapid eye movement (concurrent with low chin tone); (c) irregular respiration; (d) mouthing, sucking, twitches, or brief head movements; and (e) EEG exhibits a continuous pattern without sleep spindles; (11) because rapid eye movements may not be seen on every page, epochs following an epoch of definite R in the absence of rapid eye movements may be scored if the EEG is continuous without TA or sleep spindles, chin muscle tone low for the majority of the epoch; and there is no intervening arousal; (12) Score N if four or more of the following conditions are present, including regular respiration, for the majority of the epoch: (a) eyes are closed with no eye movements; (b) chin EMG tone present; (c) regular respiration; and (d) EEG patterns of either TA, HVS, or sleep spindles are present; and (13) score T sleep if an epoch contains two or more discordant PSG state characteristics (either three NREM and two REM characteristics or two NREM and three REM characteristics). These criteria for ages 0-2 mo represent far more than baby steps. Like all the other AASM Manual rules and specifications none are fixed in stone, all open for debate, discussion and revision with the fundamental goal to provide standards for comparison of methods and results. COMMENTARY A commentary on this article appears in this issue on page 291.

Abstract
OBJECTIVE The objective of this study was to compare the noise levels recorded in two different neonatal intensive care unit (NICU) settings: a pod and an open plan NICU located in the same hospital. BACKGROUND The NICU is a busy environment with ambient noise levels that often exceed established recommendations. This noise deleteriously affects the physiological stability and developmental outcomes of sick and preterm infants. Pods have reduced numbers of cots (in this case, 6) compared to open plan NICUs (in this case, 11), yet the noise levels in pods have not been reported. METHOD This study compared real-time decibel (dB) levels in an A-weighted scale, captured continuously by sound dosimeters mounted in both NICU settings for a period of 4 weeks: a pod setting and an open plan NICU. Researchers also collected observational data. RESULTS The average noise level recorded in the pod was 3 dBs less than in the open plan NICU. This result was statistically significant. However, dB recordings in both areas were over the recommended limits by 4-6 dBs, with isolated peaks between 74.5 dBs (NICU) and 75.9 dBs (pod). Observational data confirmed this correlation. CONCLUSIONS Further research to evaluate interventions to decrease the noise levels in both settings are needed, especially during times of peak activity. Staff working in these settings need to be more aware that control of acoustic levels is important in the neuroprotection of neonates. Coupling this with careful consideration to structural components and evidence-based design planning may contribute to lowering dB levels in the NICU environment.

Abstract
Premature birth is a sudden change of the sensory environment of a newborn, while their senses are still in development, especially in the stressful and noisy environment of the NICU. The study aimed to evaluate the effect of noise on the early tactile manual abilities of preterm infants (between 29 and 35 weeks PCA). Infants were randomly assigned to one of the two conditions: Silence and Noise. For each condition, two phases were introduced: a habituation phase (repeated presentation of the same object, prism or cylinder), followed by a test phase (presentation of the familiar or a novel object). In the Silence condition, they received the tactile habituation and test phases: In the Noise condition, they went through the same phases, while an alarm sounded. Sixty-three preterm infants were included. They displayed a strong and effective ability to memorize tactile manual information and to detect the difference between two shape features, but this ability seems to be impaired by the concomitant exposure to an alarm sound. This study is the first to highlight the effect of a negative stimulus on sensory functioning in premature infants. It reinforces the importance of developing environmental measures to lower the sound level in NICUs.
