Purpose:To characterize and quantify touch experienced by preterm infants in the NICU during essential nursing care, identify instances of skin-to-skin touch between infants and caregivers, and identify clinical/demographic variables associated with touch experiences.Design:Cross-sectional study.Sample:Preterm infants (N= 20) born 27–32 weeks post-menstrual age.Main Outcome Variable:Categories of touch during observations.Results:Touch experienced by infants during day and night shifts was primarily direct touch that was further categorized as general handling. During day shifts, 30 percent of direct touch was provided for comfort, but only 9.7 percent of touch was provided exclusively for comfort (i.e., without more intrusive touch). During night shifts, 10.6 percent of direct touch was provided for comfort, and 3 percent was categorized as exclusive comforting touch. Caregivers wore gloves for >89 percent of infant touch. Only the level of respiratory support was associated with touch categories during both shifts.

Background: Feeding difficulty is common in infants with CHD. Objective: The purpose of this study was to describe the feeding skills and behaviours of infants with CHD at 6–12 months of age and explore relationships between feeding, gastrointestinal distress, and gastroesophageal reflux. Methods: Parents of 30 infants with CHD completed online surveys when their infant was 6, 8, 10, and 12 months old. Surveys included parent-report measures of feeding skills (Child Oral and Motor Proficiency Scale), feeding behaviours (Pediatric Eating Assessment Tool), symptoms of gastrointestinal distress (Infant Gastrointestinal Symptoms Questionnaire), and gastroesophageal reflux (Infant Gastroesophageal Reflux Questionnaire-Revised). Results: We found that 95, 32, 67, and 30% of infants were delayed in their feeding skill development at 6, 8, 10, and 12 months, respectively. Symptoms of problematic feeding behaviours were similarly high, with 90, 62, 29, and 38% of infants meeting criteria for problematic feeding at 6, 8, 10, and 12 months, respectively. Feeding skills and behaviours were related but unique contributors. Feeding behaviours were related to both gastrointestinal distress and gastroesophageal reflux, but feeding skills were rarely related to either. Conclusions: Delayed acquisition of feeding skills and problematic feeding were common in infants with CHD. Infants with more gastrointestinal and gastroesophageal reflux symptoms had more symptoms of problematic feeding behaviours. Clinical Implications: Comprehensive assessment, targeted interventions, and early involvement of feeding specialists are important to support feeding in infants with CHD through at least the first year of life.

Presented in this paper is a worked example to demonstrate the practical application of the CEN European Technical Specification CEN/TS 19101:2022 when designing a spatial reticular structure that has been constructed inside the Santa Maria Paganica church, Italy, following severe damaged by the 2009 L’Aquila earthquake. The example showcases the use of fibre-polymer composites to create a lightweight, resilient shelter that ensures the structural integrity and seismic safety over the time interval necessary for restoration of the damaged church. This worked example summarizes the structural analysis and ULS verification checks carried out to meet the requirements of CEN/TS 19101, thereby emphasizing its effectiveness in facilitating the design process to safeguard historic sites during restoration projects., Paper 159: Special Session on Design of all FRP Structures Using CEN/TS 19101

Positive tactile experiences in the newborn period are critical to normal sensory development. Universal gloving in the neonatal intensive care unit has become a controversial issue in neonatal nursing practice. Intended to prevent infection among neonatal patients, universal gloving also hinders the provision of human touch. The purpose of this survey study was to (1) describe gloving policies in neonatal intensive care units, and (2) describe the gloving and touch practices of neonatal nurses and identify associations between these practices and demographic characteristics. The investigators developed a 19-question, anonymous survey. The survey link was distributed through the National Association of Neonatal Nurses' social media and newsletter. Of the 137 responses, only 22.1% of nurses reported unit policy requiring universal gloving. While nurses reported some ambiguity about gloving policies, surveyed nurses commonly used gloves when performing general care activities. Institutional gloving policies varied in this geographically diverse sample, but routine, bare-handed touch was an uncommon practice among neonatal nurses. Research evidence is needed to guide nursing practice and inform policy decisions regarding glove use in the neonatal intensive care unit.

Inflammation often accompanies preterm birth and contributes to poor neurodevelopment in preterm infants. The purpose of this study was to describe postnatal cytokine trajectories among non-infected very preterm infants during the first weeks of life. Blood samples for cytokine analysis were collected weekly from infants born between 28 and 31 weeks post-menstrual age. We used linear mixed models to calculate slopes for each cytokine and allowed the slopes to differ by infant biological sex and post-menstrual age at birth. Levels of interleukin-6, interleukin-8, and interleukin-1 receptor antagonist decreased, on average, during the neonatal period. Monocyte chemoattractant protein-1 levels increased over time, and tumor necrosis factor-alpha levels were stable. Interleukin-6 and interleukin-8 slopes differed by post-menstrual age at birth but were unaffected by infant sex. Knowledge of average cytokine trajectories may be useful in identifying infants with unresolving inflammation that increases their risk for poor neurodevelopment.

Introduction The purpose of this quality improvement project was to improve health-care provider consistency in addressing and documenting the use of sleep hygiene in children with neurodevelopmental disorders in alignment with evidence-based strategies. Method The project took place over 12 weeks and used a parent-completed screening tool and SmartPhrase technology incorporated into the patient note and discharge summary. A preimplementation and postimplementation query of the electronic medical record was used to determine change effectiveness. Results The postimplementation query found a 42% increase in documentation of sleep hygiene. In addition, a 55% increase in documentation of sleep hygiene with the initiation of melatonin was noted. Discussion The increase in documentation supports success of this initial practice change and demonstrates adherence to evidence-based sleep hygiene strategies. The project provided evidence of a significant improvement in electronic medical record documentation, highlighting an increased awareness of sleep issues in children with neurodevelopmental disorders.

Preterm infants experience numerous stressors in the neonatal intensive care unit. Non-pharmacological interventions, including maternal comforting touch, reduce stress responses of preterm infants; however, the effects of clinician-administered comforting touch are unclear. The purpose of this integrative review was to synthesize findings from clinical trials to determine the effect of clinician-administered comforting touch on preterm infants' acute stress responses.Eligible clinical trials were published in English between 2001 and October 2021 and reported effects of clinician-administered comforting touch on acute stress responses in preterm infants.Thirty clinical trials were included.Researchers tested the effect of comforting static touch, massage, massage with kinesthetic stimulation, sensorial saturation, and Yakson. There was significant heterogeneity in study design, comparison condition, and context of intervention delivery. Results varied; some studies demonstrated efficacy of comforting touch in reducing acute stress responses and others showed no effect. Generally, comforting touch provided during stressful procedures was associated with lower stress responses compared to standard care and was an effective adjunct to other stress management strategies. However, comforting touch alone was insufficient for managing pain, especially during skin-breaking procedures.While comforting touch may be a useful part of stress management plans for preterm infants, additional research is needed to determine when comforting touch is appropriate and effective.Comforting touch is beneficial to preterm infants and should be provided for stress management. For highly intrusive or painful procedures, comforting touch can be provided as part of a comprehensive stress management plan.

Delirium is a serious complication of pediatric critical illness. Sleep disruption is frequently observed in children with delirium, and circadian rhythm dysregulation is one proposed cause of delirium. Children admitted to the pediatric intensive care unit (PICU) experience multiple environmental exposures with the potential to disrupt sleep. Although researchers have measured PICU light and sound exposure, sleep, and delirium, these variables have not yet been fully explored in a single study. Furthermore, caregiving patterns have not often been included as a component of the PICU environment. Measuring the light and sound exposure, caregiving patterns, and sleep of critically ill children requires continuous PICU bedside data collection. This presents multiple methodological challenges. In this paper, we describe the protocol for an observational pilot study of the PICU environment, sleep, and delirium experienced by a sample of 10 critically ill children 1-4 years of age. We also evaluate and discuss the feasibility (i.e., acceptability, implementation, practicality) of the study protocol. Light and sound exposure were measured with bedside sensors. Caregiving was quantified through video recording. Sleep was measured via actigraphy and confirmed by video recording. Delirium screening with the Cornell Assessment of Pediatric Delirium was conducted twice daily, either in person or via video review. This study provides a refined measurement framework to inform future, large-scale studies and the development of nurse-driven sleep promotion interventions.

BACKGROUND: Moyamoya disease (MMD) is a peculiar disease, characterized by progressive steno-occlusion of the distal ends of bilateral internal carotid arteries and their proximal branches. Numerous studies of MMD investigated as a singular pathway, thus overlooked the complexity of MMD pathobiology. AIM: In this study, we sought to investigate the gene expression in the involved arteries to reveal the novel mechanism of MMD. MATERIALS AND METHODS: Eight middle cerebral artery (MCA) specimens were obtained from six patients underwent surgical procedure superficial temporal artery to MCA (STA-MCA bypass) for MMD and two control patients. We performed RNA extraction and microarray analysis with Agilent Whole Human Genome DNA microarray 4x44K ver.2.0 (Agilent Tech., Inc., Wilmington, DE, USA). RESULTS: From 42,405 gene probes assayed, 921 gene probes were differentially regulated in MCA of patients with MMD. Subsequent pathway analysis with PANTHER database revealed that angiogenesis, inflammation, integrin, platelet-derived growth factor (PDGF), and WNT pathways were distinctly regulated in MMD. Among genes in aforementioned pathways, SOS1 and AKT2 were the mostly distinctly regulated genes and closely associated with RAS pathway. CONCLUSION: The gene expression in MCA of patients with MMD was distinctly regulated in comparison with control MCA; presumably be useful for elucidating MMD pathobiology.

Delirium is a complication of critical illness associated with poor outcomes. Although widely studied in adults, comparatively little is understood about delirium in pediatric intensive care units (ICUs). The purpose of this integrative review is to determine the extent and nature of current evidence, identify gaps in the literature, and outline future areas for investigation of pediatric ICU delirium. Eligible articles included research reports of delirium in pediatric ICU samples published in English since 2009. After an extensive literature search and consideration for inclusion/exclusion criteria, 22 articles were chosen for review. Delirium was highly prevalent in the ICU. Delirium episodes developed early in hospitalization, lasted several days, and consisted of hypoactive or mixed motor subtypes. Frequently identified independent risk factors included young age, developmental delay, mechanical ventilation, and benzodiazepine exposure. Pediatric delirium was independently associated with increased length of stay, costs, and mortality. The long-term cognitive, psychological, and functional morbidities associated with pediatric delirium remain largely unknown. Few researchers have implemented interventions to prevent or manage delirium. There was little evidence for the efficacy or safety of pharmacological management. Multicomponent delirium bundles may significantly decrease delirium incidence. Key quality issues among studies included variation in delirium screening, low levels of evidence (i.e., observational studies), and limited ability to determine intervention efficacy in quasi-experimental designs. Although the quantity and quality of pediatric delirium research has rapidly increased, further studies are needed to understand the long-term effects of pediatric delirium and determine the efficacy and safety of interventions for prevention and management.

Background Extended hospitalization in neonatal intensive care units subjects preterm infants to multiple stress exposures that affect long-term cognitive functioning, motor development, and stress reactivity. Measurement of stress exposure is challenging with multiple measures of stress exposure in use, including counts of skin-breaking or invasive procedures or counts of noxious sensory exposures. Objectives The purpose of this analysis was to compare measures of stress exposure commonly used by researchers and to determine the predictive validity of these measures for early neurobehavior. We accomplished this objective through the following specific aims: (a) describe the stress exposures of preterm infants in the first 2 weeks of life, (b) determine the correlations among measures of stress exposure, and (c) compare the predictive validity of measures of stress exposure for early neurobehavior. Methods Very preterm infants born between 28 and 31 weeks postmenstrual age were enrolled from four neonatal intensive care units in a large Midwest city. We measured stress exposure over the first 14 days of life for each infant as a count of skin-breaking procedures, a count of invasive procedures, and cumulative scores derived from the Neonatal Infant Stressor Scale. Neurobehavior was assessed at 35 weeks postmenstrual age using the motor development and vigor and alertness/orientation subscales from the Neurobehavioral Assessment of the Preterm Infant. We used Spearman's rho to determine correlations among the measures of stress exposure and multiple linear regression to determine the predictive validity of each stress exposure measure for neurobehavioral outcomes. Results Seventy-one preterm infants were included in the analysis. We found marked variance across individuals in all measures of stress exposure. There were moderate-high correlations among the measures of stress exposure. No measure of stress exposure was associated with early neurobehavior. Discussion The stress experiences of hospitalized preterm infants vary. This variance is reflected in all measures of stress exposure. Because measures of stress exposure are highly correlated, the most objective measure requiring the least interpretation should be used. However, the currently available measures of stress exposure used in this analysis may not reflect the infant's physiological stress responses and fail to associate with early neurobehavior.

Background Pain management is an essential component of care for pediatric patients following surgery. Massage reduces self-reported postoperative pain in adults with heart disease but has received little attention in postoperative pediatric patients with complex congenital heart disease (CCHD). Objectives The aim of the study was to evaluate the effectiveness of massage compared to a rest period on postoperative pain scores and physiological responses in infants with CCHD. Methods We used a two-group randomized clinical trial design with a sample of 60 infants with CCHD between 1 day and 12 months of age following their first cardiothoracic surgery. Both groups received standard postoperative care. Group 1 received a daily 30-minute restriction of nonessential caregiving (quiet time), and Group 2 received a daily 30-minute massage. Interventions continued for seven consecutive days. Pain was measured six times daily using the Face, Legs, Activity, Cry, Consolability Pain Assessment Tool (FLACC). Average daily doses of analgesics were recorded. Heart rates (HRs), respiratory rates (RRs), and oxygen saturations (SpO2) were recorded continuously. Daily averages, pre- and postintervention FLACC scores, and physiological responses were analyzed using descriptive statistics, generalized linear mixed models repeated measures, latent growth models, and/or regression discontinuity analysis. Fentanyl-equivalent narcotic values were used as a time-varying covariate. Results Adjusted pain scores were lower for the massage group on all days except Day 7. Overall, there were no group effects on level of pain or differential rate of change in pain. However, the massage group had lower daily pain scores with small to medium effect size differences, largest at Days 4, 5, and 6, and lower average daily HR and RR. There was little difference between groups in SpO2. Infants demonstrated immediate effects of massage, with HR and RR decreasing and oxygen saturations increasing. Discussion This study provides beginning evidence that postoperative massage may reduce pain and improve physiological parameters in infants with congenital heart disease. This nonpharmacological adjunct to pain management may provide a particular benefit for this population by reducing demand on the cardiorespiratory system.

Background and PurposeThe prenatal preparing women do for infant caregiving is understudied. In this pilot, multimethods study, we examined motivation for preparing for infant caregiving of women in their third trimester of pregnancy expecting either a healthy infant or an infant with complex congenital heart disease (CCHD).MethodsEleven women expecting a healthy infant and four expecting an infant with CCHD completed a questionnaire and were interviewed. Preparing was reported in context of expectations, intentions, and goals and in personal, family, and infant conditions. Motivation for preparing was expressed through an interview about caregiving issues women were working on. Intensity of motivation was estimated by self-report of the time infant caregiving issues were in thought or action. Effect sizes were calculated for between group differences in motivation intensity. Interview data were examined with directed content analysis.ResultsIntensity of motivation was higher for women expecting an infant with CCHD for issues of Knowing What and How to prepare. Women expecting an infant with CCHD reported uncertainty about how they would feed their babies given their health condition. Interviews yielded new motivations encompassing issues of family and working with the parent partner.ImplicationsAssessment of issues women are working on prenatally, indicating motivations for preparing for infant caregiving, and of the intensity of motivations advances culturally-attuned and family-centered preparation. Knowledge of these issues and motivation intensity could orient clinical care to supporting women in developing well-informed expectations, intentions, and goals culturally suited to postnatal learning and infant needs.
