[PMID: 33931736 PMCID: PMC8556395 DOI: 10.1038/s41390-021-01554-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Revised: 04/09/2021] [Accepted: 04/11/2021] [Indexed: 11/12/2022]
Abstract
BACKGROUND Enriched language exposure may benefit infants in the neonatal intensive care unit. We hypothesized that changes in neonatal electroencephalogram (EEG) coherence during sleep, in response to maternal voice exposure, predict language development. METHODS Convalescent neonates underwent 12-h polysomnography. A recording of the mother's voice was randomized to continuous playback in the first or second 6 h. We calculated the imaginary coherence (ICOH-a measure of functional connectivity) between EEG leads. Spearman correlations were computed between ICOH and 18-month Bayley-III language scores. RESULTS Thirty-five neonates were included (N = 18 33-to-<35 weeks gestation; N = 17 ≥ 35 weeks). Predictive value of ICOH during neonatal non-rapid eye movement (NREM) sleep was left lateralized, and varied with gestational age and voice playback. ICOH in the left-hemispheric (C3-Cz; T3-Cz) channels across multiple EEG frequency bands was associated with 18-month language scores (rho = -0.34 to -0.48). The association was driven by neonates born at 33-34 weeks gestation, and a trend suggested a possible effect of maternal voice at some EEG frequencies. Right hemisphere ICOH (C4-Cz; T4-Cz) was not associated with language outcome. CONCLUSIONS Left-hemispheric EEG functional connectivity during neonatal NREM sleep shows early signs of physiologic asymmetry that may predict language development. We speculate that sleep analyses could have unique prognostic value. IMPACT During neonatal NREM sleep, EEG functional connectivity predicts future language development. Left temporal and central EEG coherence-specifically the imaginary component of coherence-is predictive, whereas the same analysis from the right hemisphere is not. These results appear to vary according to the infant's gestational age, and a trend suggests they may be enhanced by measuring functional connectivity during exposure to the mother's voice. These findings identify early evidence of physiologic differentiation within the cerebral hemispheres and raise the possibility that neonatal NREM sleep has a role to play in language development.

Comparing light and noise levels before and after a NICU change of design. J Perinatol 2021; 41:2235-2243. [PMID: 33712715 DOI: 10.1038/s41372-021-01007-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Revised: 12/04/2020] [Accepted: 02/11/2021] [Indexed: 02/05/2023]
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.

Abstract
Many challenges have been noted in the implementation of developmentally-supportive care principles in neonatal intensive care units, despite evidence that adhering to such care principles achieves positive results for the neonate. The aim of this study was to explore and describe compliance in adhering to developmentally-supportive care principles implemented in one neonatal intensive care unit in South Africa. An exploratory design was used in this qualitative study with purposive sampling to select eligible neonatal intensive care registered nurses (n = 14) as participants. Participants all worked in a 10 bed neonatal intensive care unit at a large tertiary care public hospital. Six audio-recorded interviews were conducted, with recordings subsequently transcribed and analyzed. Three main themes were identified: value of developmentally-supportive care, nature of developmentally-supportive care, and barriers to developmentally-supportive care. One of the main themes had subthemes, which substantiated the findings, and included parent involvement, nurse engagement, and holistic care. Study outcomes offer insight into the development or revision of policies and practices, which are crucial when implementing developmentally-supportive care, particularly in resource-poor settings where challenges are magnified.

Abstract
Historically, newborns, and especially premature newborns, were thought to "feel nothing." However, over the past decades, a growing body of evidence has shown that newborns are aware of their environment, but the extent and the onset of some sensory capacities remain largely unknown. The goal of this review is to update our current knowledge concerning newborns' perceptual world and how ready they are to cope with an entirely different sensory environment following birth. We aim to establish not only how and when each sensory ability arises during the pre-/postbirth period but also discuss how senses are studied. We conclude that although many studies converge to show that newborns are clearly sentient beings, much is still unknown. Further, we identify a series of internal and external factors that could explain discrepancies between studies, and we propose perspectives for future studies. Finally, through examples from animal studies, we illustrate the importance of this detailed knowledge to pursue the enhancement of newborns' daily living conditions. Indeed, this is a prerequisite for assessing the effects of the physical environment and routine procedures on newborns' welfare.

Abstract
BACKGROUND Little is known of educators' knowledge of the impact of preterm birth on academic achievement and nothing is known of parental perspective of this knowledge. AIMS To examine the knowledge of the impact of preterm birth on academic achievement amongst Canadian educators, characterize educators' attitudes towards these challenges, and examine parental perspectives of the educational system for their preterm child. STUDY DESIGN AND METHODS This was a mixed methods study involving kindergarten to Grade 3 educators and parents of preterm children aged 4-8 years. Focus groups were conducted with 35 educators and surveys were collected from 138 educators and 174 parents. Thematic analysis was employed for focus group data and findings from surveys were summarized using descriptive statistics. RESULTS Themes identified from focus groups included: educators' knowledge was experiential, limited information sharing by parents, and lack of resources. No consensus existed amongst educators on facilitators or barriers in the educational system to help children born preterm. On the parent survey, parental disclosure of medical history was more frequent with lower gestational age. Most parents (94.9%, 130/137) advocated for extended neonatal follow-up and only 59.9% (82/137) expressed confidence that the school was meeting their child's needs. The educator survey confirmed these themes, except educators advocated for disclosure of the child's medical history (91.7%, 100/109). Additional qualifications and experience enhanced educators' knowledge, being a parent of a child born preterm did not. CONCLUSION Educators are unprepared to address the academic challenges for the preterm child and training is needed. Parents and providers need to be prepared to advocate.

Abstract
The focus of neonatal nursing has shifted from a highly technical approach to one of supportive interventions and a more individualized developmental approach. Developmental care is described as a philosophy of care that requires rethinking the relationships between infants, families, and healthcare professionals. Various models of developmental care exist; however, they all include a variety of activities designed to manage the environment and individualize the care provided to premature and/or sick infants.

Abstract
Sensory development is complex, with both morphologic and neural components. Development of the senses begins in early fetal life, initially with structures and then in-utero stimulation initiates perception. After birth, environmental stimulants accelerate each sensory organ to nearly complete maturity several months after birth. Vision and hearing are the best studied senses and the most crucial for learning. This article focuses on the cranial senses of vision, hearing, smell, and taste. Sensory function, embryogenesis, external and genetic effects, and common malformations that may affect development are discussed, and the corresponding sensory organs are examined and evaluated.

Abstract
BackgroundNew hospital design includes more single room accommodation but there is scant and ambiguous evidence relating to the impact on patient safety and staff and patient experiences.ObjectivesTo explore the impact of the move to a newly built acute hospital with all single rooms on care delivery, working practices, staff and patient experience, safety outcomes and costs.Design(1) Mixed-methods study to inform a pre-/post-‘move’ comparison within a single hospital, (2) quasi-experimental study in two control hospitals and (3) analysis of capital and operational costs associated with single rooms.SettingFour nested case study wards [postnatal, acute admissions unit (AAU), general surgery and older people’s] within a new hospital with all single rooms. Matched wards in two control hospitals formed the comparator group.Data sourcesTwenty-one stakeholder interviews; 250 hours of observation, 24 staff interviews, 32 patient interviews, staff survey (n = 55) and staff pedometer data (n = 56) in the four case study wards; routinely collected data at ward level in the control hospitals (e.g. infection rates) and costs associated with hospital design (e.g. cleaning and staffing) in the new hospital.Results(1) There was no significant change to the proportion of time spent by nursing staff on different activities. Staff perceived improvements (patient comfort and confidentiality), but thought the new accommodation worse for visibility and surveillance, teamwork, monitoring, safeguarding and remaining close to patients. Giving sufficient time and attention to each patient, locating other staff and discussing care with colleagues proved difficult. Two-thirds of patients expressed a clear preference for single rooms, with the benefits of comfort and control outweighing any disadvantages. Some patients experienced care as task-driven and functional, and interaction with other patients was absent, leading to a sense of isolation. Staff walking distances increased significantly after the move. (2) A temporary increase in falls and medication errors within the AAU was likely to be associated with the need to adjust work patterns rather than associated with single rooms, although staff perceived the loss of panoptic surveillance as the key to increases in falls. Because of the fall in infection rates nationally and the low incidence at our study site and comparator hospitals, it is difficult to conclude from our data that it is the ‘single room’ factor that prevents infection. (3) Building an all single room hospital can cost 5% more but the difference is marginal over time. Housekeeping and cleaning costs are higher.ConclusionsThe nature of tasks undertaken by nurses did not change, but staff needed to adapt their working practices significantly and felt ill prepared for the new ways of working, with potentially significant implications for the nature of teamwork in the longer term. Staff preference remained for a mix of single rooms and bays. Patients preferred single rooms. There was no strong evidence that single rooms had any impact on patient safety but housekeeping and cleaning costs are higher. In terms of future work, patient experience and preferences in hospitals with different proportions of single rooms/designs need to be explored with a larger patient sample. The long-term impact of single room working on the nature of teamwork and informal learning and on clinical/care outcomes should also be explored.FundingThe National Institute for Health Research Health Services and Delivery Research programme.

Abstract
The intrauterine environment allows the fetus to begin hearing low-frequency sounds in a protected fashion, ensuring initial optimal development of the peripheral and central auditory system. However, the auditory nursery provided by the womb vanishes once the preterm newborn enters the high-frequency (HF) noisy environment of the neonatal intensive care unit (NICU). The present article draws a concerning line between auditory system development and HF noise in the NICU, which we argue is not necessarily conducive to fostering this development. Overexposure to HF noise during critical periods disrupts the functional organization of auditory cortical circuits. As a result, we theorize that the ability to tune out noise and extract acoustic information in a noisy environment may be impaired, leading to increased risks for a variety of auditory, language, and attention disorders. Additionally, HF noise in the NICU often masks human speech sounds, further limiting quality exposure to linguistic stimuli. Understanding the impact of the sound environment on the developing auditory system is an important first step in meeting the developmental demands of preterm newborns undergoing intensive care.

Abstract
Previous studies separately examined the effects of positioning or environmental stressors on preterm infants' sleep and stress. Since positioning and environmental stressors occur simultaneously during infant hospitalization exploring these variables in the same study may offer new insights. A quasi-experimental study by one-group interrupted time-series design. In the current study, a total of 22 preterm infants were enrolled. Each infant was moved to either the supine or prone position for an hour at a time. Infants were videotaped and the sleep-wake states, stress behaviours and environmental conditions (light, noise and stimulation/handling) were recorded during the observation period. A total of 80 observations from 22 infants were accrued. In the supine position, preterm infants demonstrated more frequent waking states after adjusting for various environmental stressors (p < .01). These infants demonstrated more frequent stress behaviours in the supine position after adjusting for various environmental stressors (p < .01). These results suggest that the prone position is a more favourable position for facilitating sleep and reducing stress for preterm infants exposed to varying environmental stressors. Preterm infants present different stress behaviours in response to varying types of environmental stimuli.

Abstract
Majority of hearing-loss cases with extremely preterm infants have no known etiology. There is a growing concern that the administration of aminoglycoside treatment in the noisy environment of the Neonatal Intensive Care Unit (NICU) may lead to hair-cell damage and subsequent auditory impairments. In addition, several mitochondrial DNA mutations are known to have been associated with aminoglycoside-induced hearing loss. This review provides a systematic analysis of the research in this area and elucidates the multifactorial mechanisms behind how mitochondrial DNA mutations, aminoglycosides and loud noise can potentiate ototoxicity in extremely preterm neonates. Recommended steps to minimize the risk of ototoxicity and improve clinical care for NICU infants are discussed.

Abstract
Neonatal intensive care unit (NICU) light and noise may be stressful to preterm infants. This research evaluated the physiological stability of 54 infants born at 28- to 32-weeks' gestational age while wearing eye goggles and earmuffs for a 4-hour period in the NICU. Infants were recruited from four NICUs of university-affiliated hospitals and randomized to the intervention-control or control-intervention sequences. Heart rate (HR), heart rate variability (HRV), and oxygen saturation (O2 sat) were collected using the SomtéTM device. Confounding variables such as position and handling were assessed by videotaping infants during the study periods. Results indicated that infants had more stress responses while wearing eye goggles and earmuffs since maximum HR was found to be significantly higher and high-frequency power of HRV significantly lower during the intervention as compared with the control period. Therefore, this intervention is not recommended for the clinical practice.
