Abstract
Neurodevelopmental delays in intensive care neonates are common but difficult to predict. In children, hemisphere differences in cortical processing of speech are predictive of cognitive performance. We hypothesized that hemisphere differences in auditory event-related potentials in intensive care neonates are predictive of neurodevelopment in infancy, even in those born preterm. Event-related potentials to speech sounds were prospectively recorded in 57 infants (gestational age 24-40 weeks) prior to discharge. The Developmental Assessment of Young Children was performed at 6 and 12 months. Hemisphere differences in mean amplitudes increased with postnatal age (P < .01) but not with gestational age. Greater hemisphere differences were associated with improved communication and cognitive scores at 6 and 12 months, but decreased in significance at 12 months after adjusting for socioeconomic and clinical factors. Auditory cortical responses can be used in intensive care neonates to help identify infants at higher risk for delays in infancy.

Abstract
BACKGROUND Children being cared for in hospital often undergo multiple diagnostic and therapeutic procedures. Procedure-related pain, anxiety, and distress may consequently place a significant burden on the children. Although standards for pain management exist, procedure-related pain remains inadequately treated. OBJECTIVE To determine the frequency and pain intensity of procedures in children, as well as the associated pharmacologic interventions to manage the pain in a Danish University Hospital. METHODS During a 3-month period in 2013, a structured questionnaire was used to prospectively record all procedures performed on children from 1 month to 18 years of age. Directly after the procedure, the pharmacologic pain management interventions and the pain intensity were recorded. Pain intensity was measured by using age-appropriate pain scales. Positioning and prior experience with the procedure were recorded. RESULTS Of the 316 children included in the study, 72% experienced none to mild pain, 8.5% experienced moderate to severe pain during the procedures, and 65% had a pharmacologic pain management intervention. Significant higher median VAS score was found during venipuncture in the children sitting on the lap of their parents compared with other positions (P < 0.05), and significant lower median VAS score was found in children who had experienced the procedure before (P < 0.05). CONCLUSION Most children experienced mild pain during procedures. The children's positioning during the procedure and prior experience with the procedure seem to influence their experience of procedural pain and it is therefore essential that therapy is tailored for each child and includes a multimodal approach.

Abstract
Anesthetic neurotoxicity has been a hot topic in anesthesia for the past decade. It is of special interest to pediatric anesthesiologists. A subgroup of children potentially at greater risk for anesthetic neurotoxicity, based on a prolonged anesthetic exposure early in development, are those children receiving anesthesia for surgical repair of congenital heart disease. These children have a known risk of neurologic deficit after cardiopulmonary bypass for surgical repair of congenital heart disease. Yet, the type of anesthesia used has not been considered as a potential etiology for their neurologic deficits. These children not only receive prolonged anesthetic exposure during surgical repair, but also receive repeated anesthetic exposures during a critical period of brain development. Their propensity to abnormal brain development, as a result of congenital heart disease, may modify their risk of anesthetic neurotoxicity. This review article provides an overview of anesthetic neurotoxicity from the perspective of a pediatric cardiac anesthesiologist and provides insight into basic science and clinical investigations as it relates to this unique group of children who have been studied over several decades for their risk of neurologic injury.

Abstract
The present study analyzed the links between prematurity, attention, and global cognitive performance in infancy and early childhood. At 7 months, focused attention (FA) was examined with an object examination task in 93 preterm infants (39 of them born extremely/very preterm, 54 born moderately/late preterm, and 38 infants born full-term). Global cognition was assessed at 7 and 24 months with the Bayley-II cognitive scale. Groups did not differ with respect to global cognitive performance but FA of infants born extremely/very preterm was significantly lower than in infants born moderately/late preterm. FA correlated significantly with both prematurity and cognitive performance at 7 months of age but not with global cognition in childhood. Findings point to a subtle adverse effect of prematurity on early attention and reveal evidence for the mediating role of FA on the effect of prematurity on cognition.

Abstract
Several lines of evidence indicate that the risk of developing schizophrenia is significantly enhanced following postnatal exposure to environmental insults occurring during the critical periods of early central nervous system development. The hippocampus is a brain structure that has been associated with the neuropathology of schizophrenia. Neonatal epileptic seizures in rat pups can affect the construction of hippocampal networks. Patients with schizophrenia exhibit deficits in an operational measure of sensorimotor gating: prepulse inhibition (PPI) of startle. PPI is the normal reduction in the startle response caused by a low intensity non-startling stimulus (prepulse) which is presented shortly before the startle stimulus (pulse). The aim of the present study was to investigate if prolonged epileptic seizures, occurring during postnatal brain development, alter prepulse inhibition (PPI) response of acoustic startle reflex and hippocampal volume of rats tested later in life (post-pubertal phase). Pilocarpine-induced status epilepticus (SE) was induced in postnatal days (PNDs) 7-9 in rat pups. On PND56, the animals were tested in the acoustic startle/PPI paradigm. Hippocampal volume was measured in histological brain slices using the Cavalieri's principle. Dorsal and ventral hippocampi were measured bilaterally. Our results demonstrate that animals subjected to SE presented deficits in PPI when tested in adulthood. Dorsal hippocampal volume was reduced in rats that experienced severe neonatal seizures.

Abstract
AIMS The study was designed to evaluate the newborn (NB) stress response during the inpatient time in the neonatal intensive care unit. METHODS A quantitative, prospective, observational study was conducted with two NB groups. The first group consisted of 12 NB patients in the neonatal intensive care unit as the experimental group (EG), and the second included 43 NBs who were sent to their own homes and were considered the control group (CG). The EG's salivary cortisol concentration was measured on the 2nd day (D2) and 9th day (D9) of life. The CG's salivary cortisol concentration was measured on the 14th day of life at the child's own home. RESULTS The salivary cortisol concentration levels for the EG on D2 and D9 and for the CG were 4.3151 ± 2.6492, 1.826 ± 1.2252, and 1.0166 ± 0.8300 ng/dl, respectively. These findings indicated the presence of an adrenal response to stress during the first inpatient days. CONCLUSIONS The salivary cortisol concentration is an accurate method to indicate neonatal stress. The glucocorticoids frequently used in the prenatal period suppress the adrenal glands and interfere with the stress response.

Abstract
Background An understanding of perceptions of parents and health caregivers who assist critically ill neonates is necessary to comprehend their actions and demands. Therefore this study aim to analyze the agreement among parents, nurse technicians and pediatricians regarding the presence and intensity of pain and distress in mechanically ventilated and intubated newborn infants. Methods Cross-sectional study comprising 52 infants and 52 trios of adults composed of one parent, one nurse technician, and one pediatrician who all observed the same infant. All infants were intubated and under mechanical ventilation and were not handled during the observations. Each newborn was simultaneously observed by the trio of adults for 1 minute to evaluate the presence of pain and distress. The intensity of pain and distress that the adults believed was felt by the infants was marked in a visual analogical scale. Adults’ agreement about the simultaneous presence of pain and distress in each infant was analyzed by marginal homogeneity and Cochran tests. The agreement about the intensity of pain and distress in each infant was studied by Bland-Altman plot and intraclass correlation coefficient (ICC). Results The assessments of pain and distress were heterogeneous in all three investigated groups of adults as determined by the results of a Bland-Altman plot. The presence of distress was more frequently reported compared with pain (marginal heterogeneity, p < 0.01). The pain and distress scores in each adult group were not correlated as shown by ICC [parents, 0.36 (95% CI: 0.01-0.63); nurses 0.47 (0.23-0.66); pediatricians, 0.46 (0.22-0.65)]. Conclusions Adults systematically underscore pain in comparison to distress in mechanically ventilated newborns, without recognizing the association between them.

Abstract
Background White matter injury (WMI) is the major antecedent of cerebral palsy in premature infants, and is often associated with maternal infection and the fetal inflammatory response. The current study explores the therapeutic potential of glutamate receptor blockade or cyclooxygenase-2 (COX-2) inhibition for inflammatory WMI. Methods Using fetal ovine derived mixed glia cultures exposed to tumour necrosis factor-α (TNF-α) or lipopolysaccharide (LPS), the expression of alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionate (AMPA) and N-methyl D-aspartate (NMDA) glutamate receptors and their contribution to inflammation mediated pre-oligodendrocyte (OL) death was evaluated. The functional significance of TNF-α and COX-2 signalling in glutamate release in association with TNF-α and LPS exposure was also assessed. Results AMPA and NMDA receptors were expressed in primary mixed glial cultures on developing OLs, the main cell-type present in fetal white matter at a period of high risk for WMI. We show that glutamate receptor expression and configuration are regulated by TNF-α and LPS exposure, but AMPA and NMDA blockade, either alone or in combination, did not reduce pre-OL death. Furthermore, we demonstrate that glutamate and prostaglandin E2 (PGE2) release following TNF-α or LPS are mediated by a TNF-α-COX-2 dependent mechanism. Conclusions Overall, these findings suggest that glial-localised glutamate receptors likely play a limited role in OL demise associated with chronic inflammation, but supports the COX-2 pathway as a potential therapeutic target for infection/inflammatory-mediated WMI.

Abstract
BACKGROUND Breast feeding duration has been associated with improved cognitive development in children. However, few population-based prospective studies have evaluated dose-response relationships of breastfeeding duration with language and motor development at early ages, and results are discrepant. METHODS The study uses data from the prospective mother-child cohort ('Rhea' study) in Crete, Greece. 540 mother-child pairs were included in the present analysis. Information about parental and child characteristics and breastfeeding practices was obtained by interview-administered questionnaires. Trained psychologists assessed cognitive, language and motor development by using the Bayley Scales of Infant Toddler Development (3rd edition) at the age of 18 months. RESULTS Duration of breast feeding was linearly positively associated with all the Bayley scales, except of gross motor. The association persisted after adjustment for potential confounders with an increase of 0.28 points in the scale of cognitive development (β=0.28; 95% CI 0.01 to 0.55), 0.29 points in the scale of receptive communication (β=0.29; 95% CI 0.04 to 0.54), 0.30 points in the scale of expressive communication (β=0.30; 95% CI 0.04 to 0.57) and 0.29 points in the scale of fine motor development (β=0.29; 95% CI 0.02 to 0.56) per accumulated month of breast feeding. Children who were breast fed longer than 6 months had a 4.44-point increase in the scale of fine motor development (β=4.44; 95% CI 0.06 to 8.82) compared with those never breast fed. CONCLUSIONS Longer duration of breast feeding was associated with increased scores in cognitive, language and motor development at 18 months of age, independently from a wide range of parental and infant characteristics. Additional longitudinal studies and trials are needed to confirm these results.

Abstract
OBJECTIVE To determine demographic, maternal, and child factors associated with socioemotional (SE) problems and chronic stress in 1-year-old children. STUDY DESIGN This was a prospective, longitudinal, community-based study, which followed mother-infant dyads (n = 1070; representative of race, education, and income status of Memphis/Shelby County, Tennessee) from midgestation into early childhood. Child SE development was measured using the Brief Infant-Toddler Social and Emotional Assessment in all 1097 1-year-olds. Chronic stress was assessed by hair cortisol in a subsample of 1-year-olds (n = 297). Multivariate regression models were developed to predict SE problems and hair cortisol levels. RESULTS More black mothers than white mothers reported SE problems in their 1-year-olds (32.9% vs 10.2%; P < .001). In multivariate regression, SE problems in blacks were predicted by lower maternal education, greater parenting stress and maternal psychological distress, and higher cyclothymic personality score. In whites, predictors of SE problems were Medicaid insurance, higher maternal depression score at 1 year, greater parenting stress and maternal psychological distress, higher dysthymic personality score, and male sex. SE problem scores were associated with higher hair cortisol levels (P = .01). Blacks had higher hair cortisol levels than whites (P < .001). In the entire subsample, increased hair cortisol levels were associated with higher parenting stress (P = .001), lower maternal depression score (P = .01), lower birth length (P < .001), and greater length at 1 year of age (P = .003). CONCLUSION Differences in maternal education, insurance, mental health, and early stress may disrupt SE development in children. Complex relationships between hair cortisol level in 1-year-olds and maternal parenting stress and depression symptoms suggest dysregulation of the child's hypothalamic-pituitary-adrenal axis.

Abstract
BACKGROUND Presently the heart rate is monitored in the Neonatal Intensive Care Unit with contact sensors: electrocardiogram or pulse oximetry. These techniques can cause injuries and infections, particularly in very premature infants with fragile skin. Camera based plethysmography was recently demonstrated in adults as a contactless method to determine heart rate. AIM To investigate the feasibility of this technique for NICU patients and identify challenging conditions. STUDY DESIGN AND PARTICIPANTS Video recordings using only ambient light were made of 19 infants at two NICUs in California and The Netherlands. Heart rate can be derived from these recordings because each cardiovascular pulse wave induces minute pulsatile skin color changes, invisible to the eye but measurable with a camera. RESULTS In all infants the heart beat induced photoplethysmographic signal was strong enough to be measured. Low ambient light level and infant motion prevented successful measurement from time to time. CONCLUSIONS Contactless heart rate monitoring by means of a camera using ambient light was demonstrated for the first time in the NICU population and appears feasible. Better hardware and improved algorithms are required to increase robustness.

Abstract
OBJECTIVE To compare retrospective use of oral sucrose (SUC) vs oral sucrose plus lidocaine ring block (SUC + RB) in the management of pain during neonatal circumcision. METHODS A retrospective review of medical records of newborns circumcised using the "Neonatal Infant Pain Scale" was done. RESULTS With regard to pain, the SUC group had a significantly greater percentage of those with pain than the SUC + RB group at 1 minute (77.7% vs 69.4%; P = .01) and 5 minutes (65.7% vs 55.7%; P = .004). There was no significant pain difference at 30 minutes. In the multivariate logistic regression analyses, those in the SUC group had significantly greater odds for pain at 1 minute than those in the SUC + RB group (odds ratio 1.45, 95% confidence interval 1.04-2.02; P = .03). No significant difference was noted at 5 minutes. Each of the SUC and SUC + RB groups had significant decreases in pain percentages at 5 minutes and 30 minutes (P <.001). In addition, post-term gestational age had significantly greater odds for pain at 5 minutes (odds ratio 3.67, 95% confidence interval 1.51-8.93; P = .004). CONCLUSION We found that sucrose use alone as compared with sucrose and ring block combined had greater odds for pain at 1 minute but not at 5 minutes. In addition, those with post-term gestational age had greater odds for pain at 5 minutes as compared with those with regular gestational age. We recommend for hospital-based circumcision using clamps, the use of combined sucrose and ring block for increased analgesia. In addition, for post-term neonates, we recommend greater focus on pain levels, including considering higher dosages of pain medications.

Abstract
Prolonged early-life seizures are associated with disruptions of affective and cognitive function. Postictal disturbances, temporary functional deficits that persist for hours to days after seizures, have not yet been thoroughly characterized. Here, we used kainic acid (KA) to induce status epilepticus (SE) in immature rats at three developmental stages (postnatal day (P) 15, 21, or 30) and subsequently assessed spatial learning and memory in a Barnes maze, exploratory behavior in an open field, and the spatiotemporal distribution of cell injury during the first 7-10 days of the postictal period. At 1 day post-SE, P15-SE rats showed no deficit in the Barnes maze but were hyperexploratory in an open field compared with their littermate controls. In contrast, P21- and P30-SE rats exhibited markedly impaired performance in the Barnes maze and exhibited significantly reduced open field exploration suggestive of anxiety-like behavior. These behavioral changes were transient in P15 rats but more persistent in P21 and enduring in P30 rats after KA-SE. The time course of behavioral deficits in P21 and P30 rats was temporally correlated with the presence of neuronal injury in the lateral septal nuclei, amygdala, and ventral subiculum/CA1, regions involved in modulation of the hypothalamic-pituitary-adrenal stress response.

Abstract
BACKGROUND The implementation of the Newborn Individualized Developmental Care and Assessment Program (NIDCAP) requires a significant effort from all professionals involved. AIM To determine the necessary requirements and barriers perceived by health professionals in the implementation of the NIDCAP. STUDY DESIGN A questionnaire covering requirements and obstacles perceived in the implementation of the NIDCAP was developed and validated in two Spanish level III neonatal intensive care units. The questionnaire was answered by 305 health professionals (response rate of 85%). RESULTS The requirements identified in the questionnaire were considered by most respondents as necessary to implementing the NIDCAP, especially more time, education, and staff. Nurses, compared to doctors, thought that more staff was necessary (93% vs. 74%; p < .01). The main obstacle identified in the survey was lack of coordination among different professionals (77%), followed by noise level in the unit (35%). Doctors, in comparison to nurses, considered noise level (61% vs. 23%; p < .01) and nursing staff (56% vs. 29%; p = .05) the most relevant obstacles to NIDCAP implementation. The more experienced professionals perceived their own colleagues as an obstacle, particularly among nursing staff. CONCLUSIONS The implementation of the NIDCAP requires a series of conditions that confirm it is not a trivial process but rather a somewhat laborious one. The lack of coordination among different professionals is often considered the main obstacle.

Abstract
Accurate pain assessment in preterm and term neonates in the neonatal intensive care unit (NICU) is of vital importance because of the high prevalence of painful experiences in this population, including both daily procedural pain and postoperative pain. Over 40 tools have been developed to assess pain in neonates, and each NICU should choose a limited number of pain assessment tools for different populations and contexts. Only two pain assessment tools have a metric adjustment to account for differences of pain assessment in prematurity. Preterm neonates do not display behavior and physiologic indicators of pain as reliably and specifically as full term infants, and preterm infants are vulnerable to long term sequelae of painful experiences. "Brain-oriented" approaches for more objective measurement of pain in neonates may become available in the future. In the meantime, neonatal pain assessment tools need to be taught, implemented, and their ongoing use optimized to form a consistent, reproducible basis for the safe and effective treatment of neonatal pain.

Abstract
PURPOSE This study was conducted to test the hypothesis that skin-to-skin contact (SSC) would reduce hepatitis B vaccine injection pain in full-term neonates. DESIGN Randomized controlled trial (RCT). SAMPLE Thirty-six mother-;neonate dyads were randomly assigned to SSC or control groups. MAIN OUTCOMES Cry time (CT ), behavioral state (BSt), and heart rate (HR ) were measured throughout the 16-minute protocol. HR and BSt were measured every 30 seconds; CT was recorded continuously. RESULTS SSC neonates cried less compared with controls (23 vs 32 seconds during injection; 16 vs 72 seconds during recovery), reached calmer BSts sooner (M = 2.8 vs M = 6.5 time points), and trended toward more rapid HR decrease. SSC as described was safe and effective and merits further testing.

Abstract
BACKGROUND National and international guidelines have been published on pain control and prevention in the newborn, but data on compliance with these guidelines are lacking. AIM To document current hospital practices for analgesia at neonatal intensive care units (NICUs) 5 years after national guidelines were published in Italy. METHODS A computer-based questionnaire was sent to all registered Italian level II and level III NICUs to investigate their routine pain control practices. MAIN OUTCOME MEASURES The analgesia and sedation currently used for invasive procedures as compared with best practices. RESULTS The questionnaire was returned by 103 of the 118 NICUs (87.3%), most of which (85.4%) knew of the national guidelines on procedural pain control and prevention, and used some analgesic measures during invasive procedures. One or more nonpharmacological interventions were only used routinely by 64.1% of the NICUs for heel pricks and venipuncture, 56.0% for percutaneous insertion of central catheters, 69.7% for nasal CPAP, and 62.4% for eye tests to screen for retinopathy of prematurity. Pain medication was routinely administered at 34.3% NICUs for tracheal intubation, 46.6% for mechanical ventilation (MV), 12.9% for tracheal aspiration, 71.4% for chest tube insertion, 33.0% for lumbar puncture, and 64.0% for postoperative pain. Pain was routinely monitored at only 22.7% of the units during MV, 12.1% for nCPAP, and 21.8% postoperatively. CONCLUSION This survey showed that most Italian NICUs provide some form of analgesia and sedation for invasive procedures in accordance with national guidelines, but their routine adherence to best practices for pain control and monitoring is still suboptimal.

Abstract
Ketamine is widely used as an anesthetic, analgesic, and sedative in pediatric clinical practice and it is also listed as an illicit drug by most countries. Recent in vivo and in vitro animal studies have confirmed that ketamine can induce neuronal cell death in the immature brain, resulting from widespread neuronal apoptosis. These effects can disturb normal development further altering the structure and functions of the brain. Our recent studies further indicate that ketamine can alter neurogenesis from neural stem progenitor cells in the developing brain. Taken together, these findings identify a novel complication associated with ketamine use in premature infants, term newborns, and pregnant women. Recent data on the developmental neurotoxicity of ketamine are reviewed with proposed future directions for evaluating the safety of ketamine in these patient populations.

Abstract
Preterm birth is characterized by multiple interacting atypical constraints affecting different aspects of neuropsychological development. In the first years of life, perceptual, motor, and communicative-linguistic abilities, as well as attention, processing speed, and memory are affected by preterm birth resulting in cascading effects on later development. From school age to adolescence, a catch-up of simpler competencies (i.e., receptive lexicon) along with a more selective effect on more complex competencies (i.e., complex linguistic functions, math, motor, and executive functions) are observed, as well as a relevant incidence of behavioral outcomes. A wide heterogeneity in preterm children's neuropsychological profiles is described depending on the interaction among the degree of neonatal immaturity, medical complications, neurological damages/alterations, environmental and social factors. Severe neuromotor and sensory damages are not frequent, while low severity impairments are common among preterm children. It is argued that developmental pathways of preterm children are atypical, and not merely delayed, and are characterized by different developmental patterns and relationships among competencies.

Abstract
This article presents the elements of the Intervention section of the Infant Care Path for Physical Therapy in the Neonatal Intensive Care Unit (NICU). The types of physical therapy interventions presented in this path are evidence-based and the suggested timing of these interventions is primarily based on practice knowledge from expert therapists, with supporting evidence cited. Physical therapy intervention in the NICU is infant-driven and focuses on providing family-centered care. In this context, interventions to facilitate a calm behavioral state and motor organization in the infant, address positioning and handling of the infant, and provide movement therapy are presented.

Abstract
BACKGROUND The implementation of the Newborn Individualized Developmental Care and Assessment Program (NIDCAP) requires great effort. Few studies evaluating staff perception of NIDCAP exist, especially in Southern Europe, and these few studies usually have a low representation of the medical staff. AIMS Exploration of staff perception (neonatologists, nurses and nursing assistants) of NIDCAP during its implementation and their attitude towards it and intention to put it into practice. STUDY DESIGN This study is a descriptive survey measuring staff perceptions of NIDCAP and its effects on their work in two Spanish neonatal level III intensive care units (NICUs). Validated questionnaires were distributed to neonatologists, nurses and nursing assistants of which 305 were completed (response rate: 85%). RESULT Virtually all the items which assess the infant's well being and the parents' role received a positive evaluation. However, three items got slightly negative evaluations: NIDCAP was more time consuming and nurses' working conditions and lighting in the unit were less optimal than in earlier practices. The professionals also had a positive attitude and a willingness to use the NIDCAP. Neonatologists perceived NIDCAP more positively than the nursing staff with statistically significant differences. CONCLUSION The neonatal unit staff in two Spanish NICUs perceived NIDCAP positively. This assessment is more positive for neonatologists than for nurses.

Abstract
High negative reactivity in early childhood interferes with later academic and behavioral adjustment. Thus, investigating the origins of high negative affectivity in early childhood is of high relevance for understanding emotional morbidity after preterm birth. The present work explored (1) direct prematurity-related consequences for negative reactivity, (2) self-regulatory deficits as a mechanism indirectly relating prematurity to negative affectivity and (3) the implications of the interplay between procedural distress in the neonatal period and parenting stress for preterm children's negative reactivity. The sample was comprised of 146 preterm children (very vs. moderately to late preterm) and 86 healthy full-term children, both free of major neurological impairment. Assessment involved negative affect and parenting stress (parent-report; 12, 24 months corrected age, CA), effortful control (behavioral battery, parent report; 24 months CA) and the number of potentially distressing neonatal intensive care procedures as well as severity of illness during the neonatal period (retrospective chart review). There was no direct link from prematurity to a disposition for high negative reactivity in early childhood nor was prematurity indirectly associated with higher negative reactivity through lower levels of effortful control. The relation between neonatal pain and distress and negative affectivity depended on the level of parenting stress with low parenting stress at the end of the first year of children's life buffering the negative influence of neonatal distress. The present findings underscore the importance of complex interactions among environmental factors in processes of emotional plasticity after preterm birth thereby providing critical suggestions for follow-up care.

Abstract
BACKGROUND Administration of oral sucrose or glucose with and without non-nutritive sucking is frequently used as a non-pharmacological intervention for needle-related procedural pain relief in infants. OBJECTIVES To determine the effectiveness of sweet-tasting solutions for needle-related procedural pain in infants one month to one year of age compared with no treatment, placebo, other sweet-tasting solutions, or pharmacological or other non-pharmacological pain-relieving methods. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012); MEDLINE via Ovid (1966 to 2012); CINAHL via OVID (1982 to 2012). The World Health Organization International Clinical Trials Registry Platform was also searched for any ongoing trials. Clinical trial registries, conference proceedings and references for randomised controlled trials (RCTs) were also searched. An updated search was run to capture any new publications before finalising the review in April 2012 and no new included studies were identified. Two review authors (MK & JF) independently abstracted data and assessed quality using a standard form. Authors have been contacted for missing data. SELECTION CRITERIA Randomised-controlled trials using a sweet-tasting solution to treat pain in healthy term infants (gestational age 37 weeks and over), between one month and 12 months of age who required needle-related procedures. These procedures included but were not limited to: subcutaneous or intramuscular injections, venepuncture, and heel lance. Studies in which the painful procedure was circumcision, lumbar puncture or supra-pubic bladder aspiration were not included as they are more severe and painful than needle-related procedures. Control conditions included no treatment or placebo (water) or any other identical intervention (same appearance and consistency) without active ingredient, another sweet-tasting solution, a pharmacological pain-relieving method (e.g. paracetamol, topical anaesthetic cream), non-pharmacological pain-relieving method (e.g. distraction method, non-nutritive sucking). DATA COLLECTION AND ANALYSIS Assessment of trial quality, data extraction and synthesis of data were performed using standard methods of the Cochrane Pain, Palliative and Supportive Care Group. We report mean differences (MD) with 95% confidence intervals (CI) using fixed-effect models as appropriate for continuous outcome measures. We planned to report risk ratio (RR) and risk difference (RD) for dichotomous outcomes. The Chi(2) test and I(2) statistic were used to assess between-study heterogeneity. MAIN RESULTS Sixty-five (65) studies were identified for possible inclusion in this review. Fourteen published RCTs with a total of 1551 participants met the inclusion criteria. Duration of cry was significantly reduced in infants who were administered a sweet-tasting solution [MD -13.47 (95% CI -16.80 to -10.15)], P < 0.00001 compared with water. However, there was considerable heterogeneity between the studies (I(2) = 94%) that we were unable to explain. Meta-analysis was not able to be undertaken for any of the other outcome measures, except for cry duration, because of differences in study design. However, most of the individual studies that measured pain found sucrose to significantly reduce pain compared with the control group. One study compared sucrose and Lidocaine-prilocaine cream and no significant difference was found between the two treatments for the outcomes pain and cry duration. Due to the differences between the studies, we were unable to identify the optimal concentration, volume or method of administration of sweet-tasting solutions in infants aged one to 12 months. Further large RCTs are needed. AUTHORS' CONCLUSIONS There is insufficient evidence to confidently judge the effectiveness of sweet-tasting solutions in reducing needle-related pain in infants (one month to 12 months of age). The treatments do, however, appear promising. Data from a series of individual trials are promising, as are the results from a subset meta-analysis of studies measuring duration of crying. Further well controlled RCTs are warranted in this population to determine the optimal concentration, volume, method of administration, and possible adverse effects.

Abstract
PURPOSE General anesthetics can induce apoptotic neurodegeneration and subsequent maladaptive behaviors in animals. Retrospective human studies suggest associations between early anesthetic exposure and subsequent adverse neurodevelopmental outcomes. The relevance of animal data to clinical practice is unclear and to our knowledge the causality underlying observed associations in humans is unknown. We reviewed newly postulated neurodevelopmental risks of pediatric anesthesia and discuss implications for the surgical care of children. MATERIALS AND METHODS We queried the MEDLINE®/PubMed® and EMBASE® databases for citations in English on pediatric anesthetic neurotoxicity with the focus on references from the last decade. RESULTS Animal studies in rodents and primates demonstrate apoptotic neuropathology and subsequent maladaptive behaviors after exposure to all currently available general anesthetics with the possible exception of α2-adrenergic agonists. Similar adverse pathological and clinical effects occur after untreated pain. Anesthetic neurotoxicity in animals develops only after exposure above threshold doses and durations during a critical neurodevelopmental window of maximal synaptogenesis in the absence of concomitant painful stimuli. Anesthetic exposure outside this window or below threshold doses and durations shows no apparent neurotoxicity, while exposure in the context of concomitant painful stimuli is neuroprotective. Retrospective human studies suggest associations between early anesthetic exposure and subsequent adverse neurodevelopmental outcomes, particularly after multiple exposures. The causality underlying the associations is unknown. Ongoing investigations may clarify the risks associated with current practice. CONCLUSIONS Surgical care of all patients mandates appropriate anesthesia. Neurotoxic doses and the duration of anesthetic exposure in animals may have little relevance to clinical practice, particularly surgical anesthesia for perioperative pain. The causality underlying the observed associations between early anesthetic exposure and subsequent adverse neurodevelopmental outcomes is unknown. Anesthetic exposure may be a marker of increased risk. Especially in young children, procedures requiring general anesthesia should be performed only as necessary and general anesthesia duration should be minimized. Alternatives to general anesthesia and the deferral of elective procedures beyond the first few years of life should be considered, as appropriate. Participation in ongoing efforts should be encouraged to generate further data.

Abstract
Infant male circumcision continues despite growing questions about its medical justification. As usually performed without analgesia or anaesthetic, circumcision is observably painful. It is likely that genital cutting has physical, sexual and psychological consequences too. Some studies link involuntary male circumcision with a range of negative emotions and even post-traumatic stress disorder (PTSD). Some circumcised men have described their current feelings in the language of violation, torture, mutilation and sexual assault. In view of the acute as well as long-term risks from circumcision and the legal liabilities that might arise, it is timely for health professionals and scientists to re-examine the evidence on this issue and participate in the debate about the advisability of this surgical procedure on unconsenting minors.

Abstract
OBJECTIVE The effect of NIDCAP (Newborn Individualized Developmental Care and Assessment Program) was examined on the neurobehavioral, electrophysiological and neurostructural development of preterm infants with severe intrauterine growth restriction (IUGR). STUDY DESIGN A total of 30 infants, 27-33 weeks gestation, were randomized to control (C; N=17) or NIDCAP/experimental (E; N=13) care. Baseline health and demographics were assessed at intake; electroencephalography (EEG) and magnetic resonance imaging (MRI) at 35 and 42 weeks postmenstrual age; and health, growth and neurobehavior at 42 weeks and 9 months corrected age (9 months). RESULTS C and E infants were comparable in health and demographics at baseline. At follow-up, E infants were healthier, showed significantly improved brain development and better neurobehavior. Neurobehavior, EEG and MRI discriminated between C and E infants. Neurobehavior at 42 weeks correlated with EEG and MRI at 42 weeks and neurobehavior at 9 months. CONCLUSION NIDCAP significantly improved IUGR preterm infants' neurobehavior, electrophysiology and brain structure. Longer-term outcome assessment and larger samples are recommended.

Abstract
The brain's response to somatosensory stimuli is essential to experience-driven learning in children. It was hypothesized that advances in event-related potential technology could quantify the response to touch in somatosensory cortices and characterize the responses of hemiparetic children. In this prospective study of 8 children (5-8 years old) with hemiparetic cerebral palsy, both event-related potential responses to sham or air puff trials and standard functional assessments were used. Event-related potential technology consistently measured signals reflecting activity in the primary and secondary somatosensory cortices as well as complex cognitive processing of touch. Participants showed typical early responses but less efficient perceptual processes. Significant differences between affected and unaffected extremities correlated with sensorimotor testing, stereognosis, and 2-point discrimination (r > 0.800 and P = .001 for all). For the first time, a novel event-related potential paradigm shows that hemiparetic children have slower and less efficient tactile cortical perception in their affected extremities.

Abstract
Critically ill newborn infants experience stressors that may alter brain development. Using a rodent model, we previously showed that neonatal stress, morphine, and stress plus morphine treatments each influence early gene expression and may impair neurodevelopment and learning behavior. We hypothesized that the combination of neonatal stress with morphine may alter neonatal angiogenesis and/or adult cerebral blood vessel density and thus increase injury after cerebral ischemia in adulthood. To test this, neonatal Lewis rats underwent 8 h/d maternal separation, plus morning/afternoon hypoxia exposure and either saline or morphine treatment (2 mg/kg s.c.) from postnatal day 3-7. A subset received bromodeoxyuridine to track angiogenesis. Adult brains were stained with collagen IV to quantify cerebral blood vessel density. To examine vulnerability to brain injury, postnatal day 80 adult rats underwent right middle cerebral artery occlusion (MCAO) to produce unilateral ischemic lesions. Brains were removed and processed for histology 48 h after injury. Brain injury was assessed by histological evaluation of hematoxylin and eosin, and silver staining. In contrast to our hypothesis, neither neonatal morphine, stress, nor the combination affected cerebral vessel density or MCAO-induced brain injury. Neonatal angiogenesis was not detected in adult rats possibly due to turnover of endothelial cells. Although unrelated to angiogenesis, hippocampal granule cell neurogenesis was detected and there was a trend (P = 0.073) toward increased bromodeoxyuridine incorporation in rats that underwent neonatal stress. These findings are discussed in contrast to other data concerning the effects of morphine on cerebrovascular function, and acute effects of morphine on hippocampal neurogenesis.

Abstract
Managing acute procedural pain effectively in preterm infants in the neonatal intensive care unit remains a significant problem. The objectives of this study were to evaluate the efficacy of breastfeeding for reducing pain and to determine if breastfeeding skills were altered after this treatment. Fifty-seven infants born at 30-36 weeks gestational age were randomized to be breastfed (BF) or to be given a soother during blood collection. Changes in the Behavioral Indicators of Infant Pain (BIIP) and in mean heart rate (HR) across 3 phases of blood collection were measured. In the BF group, the Premature Infant Breastfeeding Behaviors (PIBBS) scale was scored before and 24 hours after blood collection. Longitudinal regression analysis was used to compare changes in Lance/squeeze and Recovery phases of blood collection between groups, with gestational age at birth, baseline BIIP scores, and mean HR included as covariates. Differences in PIBBS scores were assessed using a paired t-test. Relationships between PIBBS scores, BIIP scores, and HR were evaluated with Pearson correlations. No differences between treatment groups were found: BIIP (P=0.44, confidence interval [CI] -1.60-0.69); HR (P=0.73, CI -7.0-10.0). Infants in the BF group showed improved PIBBS scores after the treatment (P<0.01, CI -2.7 to -0.2). Lower BIIP scores during the Lance/squeeze were associated significantly with more mature sucking patterns (r=-0.39, P<0.05). Breastfeeding during blood collection did not reduce pain indices or interfere with the acquisition of breastfeeding skills. Exploratory analyses indicate there may be benefit for infants with mature breastfeeding abilities.

Abstract
Maternal deprivation in the early postnatal period significantly affects the behavior and development of different animals. Here we studied delayed effects of daily maternal deprivation (5 h/day) on physical development and behavior of white rats during postnatal days 1 to 14. Here we studied the possibility of reducing the negative consequences of deprivation by daily intranasal treatment with Semax, an analog of ACTH(4-10), in a dose of 0.05 mg/kg from postnatal days 15 to 28. It was found that maternal deprivation decelerated the growth of young rats, boosted physical activity and emotional reactivity in novel environment, and increased anxiety in one-month-old animals. Semax weakened the impact of deprivation on animal body weight and normalized the levels of anxiety in rats.

Abstract
BACKGROUND Evidence indicates that medical and demographic contextual factors (cFs) impact pain responses in preterm neonates, but the existing evidence is very heterogeneous. AIM To explore the effect of cFs on pain responses to heel-stick procedures of preterm infants. METHODS This study was a secondary analysis of data collected during a randomized controlled trial examining pain response to non-pharmacological interventions across repeated heel sticks. Five heel sticks across the first 14 days of life were videotaped. Pain response was rated with the Bernese Pain Scale for Neonates (BPSN) by four raters blinded to the heel-stick phases (baseline, heel stick, recovery). Demographic and medical cFs were extracted from medical charts. Mixed single and multiple regression analyses were performed controlling for the intervention group, site and heel-stick phase. RESULTS Apgar scores at 1 min were negatively associated with behavioural (p = 0.002) BPSN scores, while Apgar scores at 5 min after birth were positively associated with behavioural (p = 0.006) scores. Accumulated number of painful procedures (p = 0.002) and gender (p = 0.02) were positively associated with physiological scores while continuous positive airway pressure CPAP (p = 0.009) and mechanical ventilation (p = 0.005) were negatively associated. CONCLUSION Higher exposure to painful procedures, male infants and having CPAP or mechanical ventilation were cFs associated with physiological response. The only variables significantly associated with behavioural BPSN scores were Apgar scores but these relationships were inconsistent.

Abstract
Concerns for toxic effects of anesthesia to the brains of the young and the elderly are mounting. While experimental evidence for such effects in the developing brain is strong, the underlying mechanisms are less well understood and debate continues as to whether young humans are at risk for anesthetic neurotoxicity. The phenomenon of postoperative cognitive deterioration in the elderly remains controversial. Time course, severity, and whether or not it persists long term are under debate. For both patient groups, today's evidence is not sufficient to guide change in clinical practice. Well-designed research is therefore imperative to tackle this critical issue.

Stress response and procedural pain in the preterm newborn: the role of pharmacological and non-pharmacological treatments. Eur J Pediatr 2012; 171:927-33.

Abstract
UNLABELLED Repeated invasive procedures occur routinely in neonates who require intensive care, causing pain at a time when it is developmentally unexpected. Multiple lines of evidence suggest that repeated and prolonged pain exposure alters their subsequent pain processing, long-term development, and behaviour. Primary outcome of this study was to evaluate the reduction of procedural pain induced by "heel-lances" in preterm newborns with three different treatment [administration of fentanyl (FE, 1-2 μg/kg), facilitated tucking (FT), sensorial saturation (SS)]. Secondary outcome was the measurement of the levels of cytokines as markers of stress correlated to pain. A prospective randomized controlled trial (RCT) comparing three different pharmacological or non-pharmacological treatments was performed involving 150 preterm newborn (gestational age 27-32 weeks). No other analgesic treatment was performed during the study. CRIES score was used to evaluate the procedural pain. The results showed that the reduction in the pain score was greater in FE and SS groups than FS group. The differences were statistically significant (p < 0.01). The levels of IL-6, IL-8, and TNF-α were higher in the FT individuals than in the FE or SS-treated infants at 1 day (p < 0.01), at 3 days (p < 0.01), and at 7 days (p < 0.01) of life. CONCLUSIONS The findings of this study suggest that FE and SS provide a superior analgesia in preterm neonates during procedural pain. In particular, sensorial saturation seems to be an important non-pharmacological alternative treatment to prevent and reduce the procedural pain in preterm newborn.

Abstract
INTRODUCTION Using heel puncture by lancets for the determination of metabolic tests (hypothyroidism and phenylketonuria) using heel puncture is a very painful procedure. Venepuncture can be used as an alternative. OBJECTIVES To determine whether venepuncture in the dorsal side of the hand is less painful and more efficient than heel puncture in the screening test for inborn errors of metabolism, as well as comparing false positives in the hypothyroidism test. MATERIAL AND METHODS We tested 607 consecutives newborns in an observational, randomised study (280 with venepuncture, and 327 with heel puncture). Pain response was assessed using the Neonatal/Infant Pain Scale (NIPS), and the delay and duration of the first cry. We measured the number of punctures needed, and the time taken to complete the test, as well as the number of false positives in the hypothyroidism test. RESULTS Venepuncture was less painful than heel prick (NIPS 2 vs 5, P<.001), as well as in the delay (crying in 57.8% vs 90.2%, P<.0001) and duration of the cry (58 vs 104 seconds). Venepuncture was also faster (60 vs 120seconds), and required less puncture attempts. There were no differences in cases with TSH greater than 5mU/mL, or greater than or equal to 9 mU/mL. CONCLUSIONS Venepuncture is associated with less pain, is faster to perform and not is associated with more false positive cases.

Abstract
OBJECTIVE To examine the relation between the neurobehavior of very preterm infants and the level of NICU quality of developmental care. METHODS The neurobehavior of 178 very preterm infants (gestational age ≤29 weeks and/or birth weight ≤1500 g) from 25 NICUs participating in a large multicenter, longitudinal study (Neonatal Adequate Care for Quality of Life, NEO-ACQUA) was examined with a standardized neurobehavioral assessment, the NICU Network Neurobehavioral Scale (NNNS). A questionnaire, the NEO-ACQUA Quality of Care Checklist was used to evaluate the level of developmental care in each of the NICUs. A factor analyses applied to NEO-ACQUA Quality of Care Checklist produced 2 main factors: (1) the infant-centered care (ICC) index, which measures parents' involvement in the care of their infant and other developmentally oriented care interventions, and (2) the infant pain management (IPM) index, which measures the NICU approach to and the procedures used for reducing infant pain. The relations between NNNS neurobehavioral scores and the 2 indexes were evaluated. RESULTS Infants from NICUs with high scores on the ICC evidenced higher attention and regulation, less excitability and hypotonicity, and lower stress/abstinence NNNS scores than infants from low-care units. Infants from NICUs with high scores on the IPM evidenced higher attention and arousal, lower lethargy and nonoptimal reflexes NNNS scores than preterm infants from low-scoring NICUs. CONCLUSIONS Very preterm infant neurobehavior was associated with higher levels of developmental care both in ICC and in IPM, suggesting that these practices support better neurobehavioral stability.

Abstract
BACKGROUND Preterm birth is thought to have an adverse impact on cognitive development and self-regulation. AIM Examining the effect of very vs. moderately to late premature birth on cognitive development and effortful control, as well as evaluating whether effortful control explains the link between preterm birth and poorer cognitive development. SUBJECTS Fifty-eight very preterm children (<32 weeks gestation or <1500 g birth weight), 88 moderately to late preterm children (≥32 weeks gestation and ≥1500 birth weight) and 86 full-term children (≥38 weeks gestation and ≥2500 g birth weight) were examined at the corrected age of 24 months. OUTCOME MEASURES Observational and parent-report measures of effortful control as well as the Bayley Scales of Infant Development II (BSID II, Mental Scale) as a measurement of cognitive development were analyzed. RESULTS Very preterm and moderately to late preterm children showed significantly lower cognitive performance compared to full-term children. Lower effortful control scores (on observational measures, but not on parent-reports) were merely found for very preterm children compared to full-term children. Observational measures of effortful control partially mediated the effects of very preterm birth on cognitive performance, but did not explain the effects of moderately to late preterm birth on cognitive performance. CONCLUSION Preterm birth in general is related to poorer cognitive performance in toddlerhood. In addition, effortful control mediates the effects of very preterm birth on cognitive development. Findings suggest that different mechanisms link moderately to late premature birth to poor cognitive development.

Abstract
Circumcision is painful surgery and appropriate intraoperative anaesthesia and postoperative analgesia is required. This is recognised in the policies of the Royal Australasian College of Physicians and the majority of Australian State Health Departments. Nevertheless, anecdotal evidence exists that neonatal circumcision continues to be performed in Australia with either no anaesthesia or with inadequate anaesthesia. This paper presents the evidence that neonatal circumcision is painful and reviews the available anaesthetic techniques. The authors conclude that general anaesthesia is arguably the most reliable way of ensuring adequate anaesthesia, although this may mean deferment of the procedure until the child is older. Local or regional anaesthesia for neonatal circumcision ideally requires a separate skilled anaesthetist (other than the proceduralist) to monitor the patient and intervene if the anaesthesia is inadequate. Topical anaesthesia with lignocaine-prilocaine (EMLA) cream is insufficient.

Abstract
Pain is harmful to newborn infants. Oral sucrose is safe, inexpensive, and effective at preventing and reducing pain in hospitalized babies who undergo invasive procedures. The sugar can be used alone or in combination with analgesics and other nonpharmacological interventions to provide analgesia. Parents expect nurses to serve as pain advocates for the parents' newborns and to protect the babies from needless suffering. It is incumbent upon nurses to stay abreast of the current evidence and integrate use of oral sucrose into daily pain management practice in emergency, acute, and critical care units.

Abstract
INTRODUCTION Very early preterm infants (VPIs) are exposed to unpredictable noise in neonatal intensive care units. Their ability to perceive moderate acoustic environmental changes has not been fully investigated. RESULTS Physiological values of the 598 isolated sound peaks (SPs) that were 5-10 and 10-15 dB slow-response A (dBA) above background noise levels and that occurred during infants' sleep varied significantly, indicating that VPIs detect them. Exposure to 10-15 dBA SPs during active sleep significantly increased mean heart rate and decreased mean respiratory rate and mean systemic and cerebral oxygen saturations relative to baseline. DISCUSSION VPIs are sensitive to changes in their nosocomial acoustic environment, with a minimal signal-to-noise ratio (SNR) threshold of 5-10 dBA. These acoustic changes can alter their well-being. METHODS In this observational study, we evaluated their differential auditory sensitivity to sound-pressure level (SPL) increments below 70-75 dBA equivalent continuous level in their incubators. Environmental (SPL and audio recording), physiological, cerebral, and behavioral data were prospectively collected over 10 h in 26 VPIs (GA 28 (26-31) wk). SPs emerging from background noise levels were identified and newborns' arousal states at the time of SPs were determined. Changes in parameters were compared over 5-s periods between baseline and the 40 s following the SPs depending on their SNR thresholds above background noise.

Abstract
OBJECTIVE Preterm infants are exposed to multiple painful procedures in the neonatal intensive care unit (NICU) during a period of rapid brain development. Our aim was to examine relationships between procedural pain in the NICU and early brain development in very preterm infants. METHODS Infants born very preterm (N=86; 24-32 weeks gestational age) were followed prospectively from birth, and studied with magnetic resonance imaging, 3-dimensional magnetic resonance spectroscopic imaging, and diffusion tensor imaging: scan 1 early in life (median, 32.1 weeks) and scan 2 at term-equivalent age (median, 40 weeks). We calculated N-acetylaspartate to choline ratios (NAA/choline), lactate to choline ratios, average diffusivity, and white matter fractional anisotropy (FA) from up to 7 white and 4 subcortical gray matter regions of interest. Procedural pain was quantified as the number of skin-breaking events from birth to term or scan 2. Data were analyzed using generalized estimating equation modeling adjusting for clinical confounders such as illness severity, morphine exposure, brain injury, and surgery. RESULTS After comprehensively adjusting for multiple clinical factors, greater neonatal procedural pain was associated with reduced white matter FA (β=-0.0002, p=0.028) and reduced subcortical gray matter NAA/choline (β=-0.0006, p=0.004). Reduced FA was predicted by early pain (before scan 1), whereas lower NAA/choline was predicted by pain exposure throughout the neonatal course, suggesting a primary and early effect on subcortical structures with secondary white matter changes. INTERPRETATION Early procedural pain in very preterm infants may contribute to impaired brain development.

Abstract
OBJECTIVES To test the comparative effectiveness of 2 nonpharmacologic pain-relieving interventions administered alone or in combination across time for repeated heel sticks in preterm infants. METHODS A multicenter randomized controlled trial in 3 NICUs in Switzerland compared the effectiveness of oral sucrose, facilitated tucking (FT), and a combination of both interventions in preterm infants between 24 and 32 weeks of gestation. Data were collected during the first 14 days of their NICU stay. Three phases (baseline, heel stick, recovery) of 5 heel stick procedures were videotaped for each infant. Four independent experienced nurses blinded to the heel stick phase rated 1055 video sequences presented in random order by using the Bernese Pain Scale for Neonates, a validated pain tool. RESULTS Seventy-one infants were included in the study. Interrater reliability was high for the total Bernese Pain Scale for Neonates score (Cronbach's α: 0.90-0.95). FT alone was significantly less effective in relieving repeated procedural pain (P < .002) than sucrose (0.2 mL/kg). FT in combination with sucrose seemed to have added value in the recovery phase with lower pain scores (P = .003) compared with both the single-treatment groups. There were no significant differences in pain responses across gestational ages. CONCLUSIONS Sucrose with and without FT had pain-relieving effects even in preterm infants of <32 weeks of gestation having repeated pain exposures. These interventions remained effective during repeated heel sticks across time.
