    To examine what it means to be a mother of a late preterm infant including a mother's level of confidence in caring for her late preterm infant over time and the effect of maternal depression of this experience. Little is known about mothers' experiences of caring for their late preterm infants in the community, including their level of confidence and parenting stress within the context of a supported care environment by public health nurses. A mixed methods study, sequential explanatory quantitative and qualitative study. A convenience sample of mothers with LPIs (n = 71) completed questionnaires on maternal confidence (3-4 weeks and 6-8 weeks), parenting stress (6-8 weeks), social support (6-8 weeks) and postpartum depression (6-8 weeks). A purposive sample of mothers (n = 11) underwent in-depth, semi-structured interviews. Maternal confidence decreased from 3-4 weeks-6-8 weeks after delivery, and similar results were found for mothers who reported depressive symptoms. Narratives of the mothers suggested the decrease in maternal confidence over time was influenced by the demanding characteristics of the late preterm infant, the prospect of their rehospitalisation and the mother's reported interactions with public health nurses. Depression had an effect on maternal confidence; that is, the depressed mothers demonstrated less confidence about their caretaking role than the nondepressed mothers at 6-8 weeks. Mothers did not discuss mental health issues, which may reflect the protective effects of social support on emotional instability or an inability to recognise postpartum depression. The confidence of mothers with LPIs decreased over the first 2 months following delivery and being home with their infants. Assisting mothers to meet their personal needs and the needs of their infant should promote maternal skills, which will likely increase maternal confidence related to the care of their late preterm infant. Characteristics of LPIs contributed more to

    Full Text Available Due to its peculiar nutritional and non-nutritional contents, which include long-chain polyunsatured fatty acids (LC-PUFA, prebiotics, immunological factors, hormones and growth factors, breast milk shows significant advantages over infant formulas in nourishing preterm infants. Better neurocognitive outcomes, which are reported to persist far beyond the early childhood, have been largely observed in breastfed preterm infants; a role of LC-PUFA in promoting neural and retinal development is assumed. As far as the gastrointestinal tract is concerned, several evidences have reported a dose-related reduction in NEC incidence among preterm infants fed on human milk. Moreover, the higher amount of immunological factors as secretory IgA within preterm breast milk might play a remarkable role in reducing the overall infections. Despite breastfeeding in preterm infants is generally linked with lowered growth rates which might potentially affect neurocognitive outcomes, the beneficial effects of human milk on neurodevelopment prevail. Fortified human milk might better fulfill the particular nutritional needs of preterm infants. However, as breast milk fortification is difficult to carry out after the achievement of full oral feeding, some concerns on the nutritional adequacy of exclusive breastfeeding during hospitalization as well as after discharge have been raised. Finally, breastfeeding also entails maternal psychological beneficial effects, as promoting the motherhood process and the mother-child relationship, which could be undermined in those women experiencing preterm delivery. Proceedings of the 9th International Workshop on Neonatology · Cagliari (Italy · October 23rd-26th, 2013 · Learned lessons, changing practice and cutting-edge research

    In preterm infants, it is unknown whether feeding affects neural breathing pattern. By measuring the diaphragm electrical activity (Edi) waveform, we evaluated the effect of enteral feeding and compared the effects of feeding methods on neural breathing pattern and central apnea in very low birth weight preterm infants. In a prospective, randomized, crossover study, ten non-ventilated preterm infants with birth weightsapnea. Primary outcome was change in Edi min with feed. Secondary outcomes include change in Edi peak, frequency and duration of central apnea with feeding. Although intrasubject coefficient of variation was not significantly different, individual responses to feeding and feeding method were variable. No significant difference in Edi timing, Edi min, Edi peak, or apnea was observed for the different epochs. In this study cohort, neural breathing pattern does not appear to be consistently affected by enteral feeding or the feeding method. Compared with BF, SF does not appear to reduce the number or duration of apneas. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Prone sleeping is a major risk factor for sudden infant death syndrome (SIDS) and preterm infants are at significantly increased risk. In term infants, prone sleeping is associated with reduced mean arterial pressure (MAP) and cerebral tissue oxygenation index (TOI). However, little is known about the effects of sleeping position on TOI and MAP in preterm infants. We aimed to examine TOI and MAP in preterm infants after term-equivalent age, during the period of greatest SIDS risk. Thirty-five preterm and 17 term infants underwent daytime polysomnography, including measurement of TOI (NIRO-200 spectrophotometer, Hamamatsu Photonics KK, Japan) and MAP (Finapress Medical Systems, Amsterdam, Netherlands) at 2 to 4 weeks, 2 to 3 months, and 5 to 6 months postterm age. Infants slept prone and supine in active and quiet sleep. The effects of sleep state and position were determined by using 2-way repeated measures analysis of variance and of preterm birth by using 2-way analysis of variance. In preterm infants, TOI was significantly lower when prone compared with supine in both sleep states at all ages (P preterm compared with term infants at 2 to 4 weeks, in both positions (P preterm infants in the prone position at 2 to 3 months (P position in preterm infants and is lower compared with age-matched term infants, predominantly in the prone position when MAP is also reduced. This may contribute to their increased SIDS risk. Copyright © 2014 by the American Academy of Pediatrics.

  6. Optimizing Nutrition in Preterm Infants

    Full Text Available Extrauterine growth restriction is common in very preterm infants. The incidence in very-low-birth-weight infants ranges between 43% and 97% in various centers, with a wide variability due to the use of different reference growth charts and nonstandard nutritional strategies. Extrauterine growth restriction is associated with an increased risk of poor neurodevelopmental outcome. Inadequate postnatal nutrition is an important factor contributing to growth failure, as most very preterm infants experience major protein and energy deficits during neonatal intensive care unit hospitalization. First-week protein and energy intake are associated with 18-month developmental outcomes in very preterm infants. Early aggressive nutrition, including parenteral and enteral, is well tolerated in the very preterm infant and is effective in improving growth. Continued provision of appropriate nutrition (fortified human milk or premature formula is important throughout the growing care during the hospitalization. After discharge, exclusively breast-fed infants require additional supplementation. If formula-fed, nutrient-enriched postdischarge formula should be continued for approximately 9 months corrected age. Supplementation of the preterm formulas with protein would increase the protein/energy ratio (3 g/100 kcal, leading to increased lean mass with relatively decreased fat deposition. Further research is required to optimize the nutritional needs of preterm infants and to evaluate the effects of nutritional interventions on long-term growth, neurodevelopment, and other health outcomes.

    Caffeine is the most commonly used medication for treatment of apnea of prematurity. Its effect has been well established in reducing the frequency of apnea, intermittent hypoxemia, and extubation failure in mechanically ventilated preterm infants. Evidence for additional short-term benefits on reducing the incidence of bronchopulmonary dysplasia and patent ductus arteriosus has also been suggested. Controversies exist among various neonatal intensive care units in terms of drug efficacy compared to other methylxanthines, dosage regimen, time of initiation, duration of therapy, drug safety and value of therapeutic drug monitoring. In the current review, we will summarize the available evidence for the best practice in using caffeine therapy in preterm infants. PMID:26566480

    Therapeutic touch (TT), a complementary therapy, has been shown to decrease stress, anxiety, and pain in adults and children, as well as improve mobility in patients with arthritis and fibromyalgia. However, less has been reported about the effectiveness of this therapy with infants, particularly preterm infants. The aims of this research study were to explore the nature of the use of TT with preterm infants and describe a TT treatment process for this vulnerable population. Narrative inquiry and qualitative descriptive methods were used to discover knowledge about how TT is used with preterm infants. Telephone/in-person interviews and written narratives provided the data describing nurses' use of TT with preterm infants. The participants were registered nurses who practiced TT with preterm infants for varying years of experience. The participants described the responses of infants, 25 to 37 weeks postgestational age, whom they treated with TT. The infants' responses to TT included reduced heart and respiratory rates, enhanced ability to rest, improved coordination in sucking, swallowing, and breathing, and a greater ability to engage with the environment. The practitioners described the phases and elements of TT for preterm infants, which revealed unique patterns, for example, the treatment phase included the elements of smoothing and containing. The description that emerged from the practitioners' narratives of the TT treatment process for preterm infants provides preliminary data for the systematic use and evaluation of TT as an adjunct to facilitating preterm infants' physiological, behavioral, energy field development, and well-being.

    Many conventional medical monitoring devices, while not technically invasive, are nevertheless obtrusive insofar as they require contact with the patient. This obtrusiveness sometimes poses problems in daily clinical practice. The need for contact with electrodes or transducers is particularly relevant in the case of patients recovering in intensive care units where continuous monitoring is required, in turn requiring continuous direct transducer contact for prolonged periods. Among the many physiological parameters commonly acquired, the respiratory and the cardiac rates of the patients are of primary importance. Typically these two parameters are measured respectively using spirometry and electrocardiography (ECG), both involving obtrusive measurement systems requiring contact with the patient with an air conduit and electrodes. This paper presents an optical measurement method for the simultaneous assessment of respiration and heart rates based on the measurement of the chest wall movements, associated with inspiratory/expiratory activities of the lungs and by the mechanical pumping action of the heart. The measurement method has been adapted for use with preterm infants and it has been applied to 55 patients recovering in a Neonatal Intensive Care Unit. The method is based on the use of a laser Doppler vibrometer (LDVi) pointed at the left, ventral thoracic surface of the patient. LDVi-based measures of respiration and heart rate have been simultaneously acquired for each patient, in parallel with the same quantities acquired using conventional reference instrumentation (flow-meter and ECG) for comparison purposes. Results show that for respiration rate, differences with respect to the spirometer data are instrument, the simultaneous measurement of respiration and heart rates, thus reducing the burden of the number of electrodes, transducers, and other instrumentation that must be applied to the patient—a consideration that is particularly important in the

    Preterm infants are especially vulnerable to infectious diseases. Although vaccinations are a safe and effective measure to protect preterm infants from vaccine-preventable diseases, delays in vaccinations are not uncommon. The goal of this quality improvement project was to improve on time vaccinations of preterm infants hospitalized in the neonatal intensive care unit. The Plan-Do-Study-Act model of quality improvement was adopted to develop, test, and implement interventions aimed at improving timely vaccination of preterm infants. The primary outcome measure of interest was the rate of on time vaccination, which was defined as the proportion of medically eligible preterm infants who received vaccinations within 2 weeks of the recommended schedule. Baseline on time vaccination rate was only 36%. Following several Plan-Do-Study-Act cycles, a steady increase in on time vaccinations of eligible infants was observed, and a new baseline on time vaccination rate of 82% was achieved. Simple interventions implemented within the context of Plan-Do-Study-Act cycles are effective in improving timely vaccinations among preterm infants. Future research that focuses on vaccinations in preterm infants is needed to further reinforce the safety and efficacy of vaccines. Effective methods on how to disseminate and apply this knowledge to practice should also be studied.Video Abstract available at http://links.lww.com/ANC/A27.

    The major cause of osteopathy of prematurity is dietary phosphate deficiency, but secondary hyperparathyroidism caused by calcium deficiency or vitamin D deficiency is also important. Because parathyroid hormone (PTH) mobilizes calcium and phosphate from the bone, hyperparathyroidism worsens osteopathy of prematurity. In order to identify useful markers to screen for and diagnose hyperparathyroidism in preterm infants, we measured serum and urinary biochemical markers. Several biomarkers, including serum intact PTH (iPTH), were measured in urine and serum samples obtained from 95 preterm infants, and the relationship between serum iPTH and the other parameters was analyzed. Mean gestation was 33.2 ± 2.9 weeks, and mean birthweight was 1705 ± 402 g. Samples were collected around postnatal day 17.3 ± 7.4. Fourteen infants (14.7%) had iPTH >65 pg/mL. Cut-offs for serum alkaline phosphatase (ALP) and percent tubular reabsorption rate of phosphate (%TRP) were fixed at 1300 IU/L and 93%, respectively using receiver operating characteristic curves with iPTH cut-off of 65 pg/mL. Serum ALP was proven to be a good marker: ALP had a sensitivity of 78.6% and a specificity of 86.4%, while %TRP itself was not: %TRP had a sensitivity of 64.3% and a specificity of 58.0%. Combined measurement of serum ALP (>1300 IU/L) and %TRP (≤93%), however, had a specificity of 93.8% for detecting elevated iPTH. Measurement of serum ALP (>1300 IU/L) is considered as an effective screening method to detect hyperparathyroidism. In addition, combined assessment of ALP(>1300 IU/L) and %TRP(≤93%) is a good indicator of elevated iPTH in preterm infants. © 2016 Japan Pediatric Society.

  19. Pathomorphological findings in preterm infants

    Pathomorphology in the preterm infant represents an interaction of morphological organ immaturity and neonatal management with their respective sequelae. Pathomorphological examples include the modification in the morphology of hyaline membrane disease and bronchopulmonary dysplasia as a consequence of modern neonatal therapy. Hemorrhagic and ischemic/hypoxic lesions of the central nervous system may occur in age- and agent-related distributional patterns, with subependymal hemorrhage and periventricular leukomalacia representing the most important examples. The most common intestinal finding, namely, necrotizing enterocolitis, typically shows segmental alterations, the morphology of which largely depends on the dominating causative agent. Hepatic cholestasis and fatty change are mostly consequences of parenteral nutrition or hypoxic/ischemic stress. Hepatic necrosis can be associated with the latter, but may also indicate disseminated intravascular coagulation. Vascular pathomorphology is represented by thromembolic lesions, in most instances corresponding to sequelae of neonatal management. (orig.) [de

    To look at the survival pattern of extreme preterm Omani infants (23-26 weeks gestation) and compare it with the western countries. All extreme preterm Omani infants (gestational age of 23 to 26 weeks) admitted from November 1991 to February 1998 at the Neonatal Intensive Care Unit of Sultan Qaboos University Hospital were reviewed. The detailed records of the infants, including name of mother, age, gravidity, parity, route of delivery, Apgar score, time of birth, inborn or outborn, birth weight, gestational age, sex, need for resuscitation, course in the Neonatal Intensive Care Unit, admission and discharge diagnosis, and outcome were collected from the register. The infants were stratified according to the gestational age and then analyzed for the survival rate among the different gestational ages. A total of 32 extreme preterm infants were admitted to the Neonatal Intensive Care Unit of Sultan Qaboos University Hospital from November 1991 to February 1998. The mean birth weight of the cohort was noted to be 798+123 gram (Range 480-1015 grams). The mean gestational age was noted to be 25.5+0.95 weeks (Range 23-26 weeks). An equal number of males and females were noted in the cohort, with male to female ratio of 1:1. A total of 13 infants survived out of 32 infants. The overall survival rate for the cohort was noted to be 41%. For the present study, the western statistics are averaged and than compared with the Omani statistics. The survival rate for western 26 week preterm infants was (on average) 61% as compared to 44% among Omani preterm infants. The same trend of low survival was noted for 23 and 24 week Omani infants, except for only one 25 week infant. The significant lower survival rate suggests the need for more attention and improvement in the management and care provided to the extreme preterm Omani infants.

    Background Autoregulatory dysfunction is an important contributor to brain injury in premature infants, particularly intraventricular hemorrhage (IVH). The autoregulatory system acts as a filter that dampens the systemic blood flow to follow a normal cerebral perfusion profile. Methods Simultaneous arterial blood pressure and cerebral near infrared spectroscopy (NIRS) data were collected from infants born before 28 weeks estimated gestational age (EGA). The resulting data were preprocessed and then divided into non-overlapping 20-minute epochs. The transfer function estimate was calculated to determine dampening ability. Results 62 infants were prospectively recruited with a mean EGA of 25.4 ± 1.3 weeks and birth weight of 832 ± 199g. 67% were male, 24/62 had IVH, 17/62 received dopamine, 47/62 had antenatal steroid exposure, and 22/62 received fentanyl. Advancing EGA and birth weight z-score predicted stronger dampening while African-American race and IVH of any grade predicted weaker dampening. Conclusion This preliminary report suggests an impairment in dampening ability associated with immaturity, decreased birth weight z-score and African-American race. Decreased dampening is also associated with IVH, although these results cannot distinguish between decreased dampening as an antecedent or sequela of IVH. These observations should be studied in a larger sample. PMID:26571222

    Full Text Available Background/Aim. Cerebral palsy (CP is one of the leading causes of neurological impairment in childhood. Preterm birth is a significant risk factor in the occurrence of CP. Clinical outcomes may include impairment of gross motor function and intellectual abilities, visual impairment and epilepsy. The aim of this study was to examine the relationships among gestational age, type of CP, functional ability and associated conditions. Methods. The sample size was 206 children with CP. The data were obtained from medical records and included gestational age at birth, clinical characteristics of CP and associated conditions. Clinical CP type was determined according to Surveillance of Cerebral Palsy in Europe (SCPE and topographically. Gross motor function abilities were evaluated according to the Gross Motor Function Classification System (GMFCS. Results. More than half of the children with CP were born prematurely (54.4%. Statistically significant difference was noted with respect to the distribution of various clinical types of CP in relation to gestational age (p < 0.001. In the group with spastic bilateral CP type, there is a greater proportion of children born preterm. Statistically significant difference was noted in the functional classification based on GMFCS in terms of gestational age (p = 0.049, children born at earlier gestational age are classified at a higher GMFCS level of functional limitation. The greatest percentage of children (70.0% affected by two or more associated conditions was found in the group that had extremely preterm birth, and that number declined with increasing maturity at birth. Epilepsy was more prevalent in children born at greater gestational age, and this difference in distribution was statistically significant (p = 0.032. Conclusion. The application of antenatal and postnatal protection of preterm children should be a significant component of the CP prevention strategy. [Projekat Ministarstva nauke Republike

    Survival of preterm infants, which increased dramatically during the years after the introduction of neonatal intensive care, reached a plateau in the mid- to late 1990s. Neonatal morbidity, which increased initially, has decreased since 2000 and resulted in a decrease in the rates of cerebral palsy. Follow-up of preterm infants to early childhood and school age reveals higher rates of asthma, cerebral palsy, subnormal cognitive function, poorer academic achievement, and behavioral problems. Although many of the problems persist into adulthood, preterm survivors regard their overall health and quality of life similar to that of normal birth weight controls.

    This study aimed to explore the effects of individualized sensory integration interventions on the sensory processing functions of preterm infants. Thirty-four preterm infants (intervention group) at a corrected age of seven months and 34 term infants (control group) were included. The preterm infants underwent an eight-week sensory integration intervention. Before and after the intervention, the preterm infants' sensory processing functions were evaluated using the Test of Sensory Functions in Infants and compared with those of term infants. Preterm infants had significantly poorer sensory processing function preintervention when compared with term infants. There was a significant improvement in preterm infants' sensory processing functions after the sensory integration intervention. In conclusion, preterm infants should be evaluated for sensory processing disorders and individualized sensory integration interventions should be implemented. © The Author(s) 2016.

    The current study explores the effects of exposure to maternal voice on infant sucking in preterm infants. Twenty-four preterm infants averaging 35 weeks gestational age were divided randomly into two groups. A contingency between high-amplitude sucking and presentation of maternal voice was instituted for one group while the other group served as a yoked control. No significant differences were observed in sucking of the two groups, but the degree of pitch modulation of the maternal voice predicted an increase in the rate of infant sucking.

    Systemic hypotension is a relatively common complication of preterm birth and is associated with periventricular haemorrhage, periventricular white matter injury and adverse neurodevelopmental outcome. Corticosteroid treatment has been used as an alternative or an adjunct to conventional treatment with volume expansion and vasopressor/inotropic therapy. To determine the effectiveness and safety of corticosteroids used either as primary treatment of hypotension or for the treatment of refractory hypotension in preterm infants. Randomized or quasi-randomised controlled trials were identified by searching the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 2, 2011), MEDLINE (1996 to Jan 2011), EMBASE (1974 to Jan 2011), CINAHL (1981 to 2011), reference lists of published papers and abstracts from the Pediatric Academic Societies and the European Society for Pediatric Research meetings published in Pediatric Research (1995 to 2011). We included all randomised or quasi-randomised controlled trials investigating the effect of corticosteroid therapy in the treatment of hypotension in preterm infants (babies with hypotension resistant to inotropes/pressors and volume therapy. We included studies comparing oral/intravenous corticosteroids with placebo, other drugs used for providing cardiovascular support or no therapy in this review. Methodological quality of eligible studies was assessed according to the methods used for minimising selection bias, performance bias, attrition bias and detection bias. Studies that evaluated corticosteroids (1) as primary treatment for hypotension or (2) for refractory hypotension unresponsive to prior use of inotropes/pressors and volume therapy, were analysed using separate comparisons. Data were analysed using the standard methods of the Neonatal Review Group using Rev Man 5.1.2. Treatment effect was analysed using relative risk, risk reduction, number needed to treat for categorical outcomes and

    Administration of endotracheal surfactant is potentially the main treatment for neonates suffering from RDS (Respiratory Distress Syndrome), which is followed by mechanical ventilation. Late and severe complications may develop as a consequence of using mechanical ventilation. In this study, conventional methods for treatment of RDS are compared with surfactant administration, use of mechanical ventilation for a brief period and NCPAP (Nasal Continuous Positive Airway Pressure), (INSURE method ((Intubation, Surfactant administration and extubation)). A randomized clinical trial study was performed, including all newborn infants with diagnosed RDS and a gestational age of 35 weeks or less, who were admitted in NICU of Valiasr hospital. The patients were then divided randomly into two CMV (Conventional Mechanical Ventilation) and INSURE groups. Surfactant administration and consequent long-term mechanical ventilation were done in the first group (CMV group). In the second group (INSURE group), surfactant was administered followed by a short-term period of mechanical ventilation. The infants were then extubated, and NCPAP was embedded. The comparison included crucial duration of mechanical ventilation and oxygen therapy, IVH (Intraventricular Hemorrhage), PDA (Patent Ductus Arteriosus), air-leak syndromes, BPD (Broncho-Pulmonary Dysplasia) and mortality rate. The need for mechanical ventilation in 5th day of admission was 43% decreased (P=0.005) in INSURE group in comparison to CMV group. A decline (P=0.01) in the incidence of IVH and PDA was also achieved. Pneumothorax, chronic pulmonary disease and mortality rates, were not significantly different among two groups. (P=0.25, P=0.14, P=0.25, respectively). This study indicated that INSURE method in the treatment of RDS decreases the need for mechanical ventilation and oxygen-therapy in preterm neonates. Moreover, relevant complications as IVH and PDA were observed to be reduced. Thus, it seems rationale to perform

    Full Text Available Introduction/Objective. Preterm birth (PB is the most important reason of neonatal mortality, and the second most common direct cause of death for children under the age of five years. The aim of this study was to analyze the clinical features and outcomes of preterm infants. Methods. The clinical data of 307 preterm infants delivered in the Qingdao University hospital from January 1, 2012 to December 31, 2012 were retrospectively analyzed. Results. The incidence of PB was 6.52%. There were 143 cases of preterm prelabour rupture of membranes (PPROM (46.58%, 66 cases of spontaneous PB (21.5%, and 98 cases of therapeutic PB (31.92%. Deliveries with gestational weeks (GW < 32 were mainly vaginal (60.72%, but deliveries with GW ≥ 32 exhibited higher C-section rate (60.99% than the vaginal delivery rate (p < 0.05. The birth weight was 2,340.46 ± 606.26 g, and the Z-score at birth was -0.15 ± 1.08. The Z-score in the group with GW within 28 to 31+6 weeks was less than that in the group with GW within 32 to 33+6 and with GW ≥ 34 (р < 0.05. The average hospital stay of preterm infants was 15.17 ± 12.35 days, and the most common complication in these preterm infants was respiratory distress syndrome with 13.92%. Conclusion. PB could cause a variety of serious complications in infants. The main causes of PB, such ас PPROM, should be actively prevented and treated; meanwhile, preterm infants should also be actively treated so as to improve their outcomes.

    Full Text Available Late preterm (LPT neonates are at a high risk for respiratory distress soon after birth due to respiratory distress syndrome (RDS, transient tachypnea of the newborn, persistent pulmonary hypertension, and pneumonia along with an increased need for surfactant replacement therapy, continuous positive airway pressure, and ventilator support when compared with the term neonates. In the past, studies on outcomes of infants with respiratory distress have primarily focused on extremely premature infants, leading to a gap in knowledge and understanding of the developmental biology and mechanism of pulmonary diseases in LPT neonates. Surfactant deficiency is the most frequent etiology of RDS in very preterm and moderately preterm infants, while cesarean section and lung infection play major roles in RDS development in LPT infants. The clinical presentation and the response to surfactant therapy in LPT infants may be different than that seen in very preterm infants. Incidence of pneumonia and occurrence of pneumothorax are significantly higher in LPT and term infants. High rates of pneumonia in these infants may result in direct injury to the type II alveolar cells of the lung with decreasing synthesis, release, and processing of surfactant. Increased permeability of the alveolar capillary membrane to both fluid and solutes is known to result in entry of plasma proteins into the alveolar hypophase, further inhibiting the surface properties of surfactant. However, the oxygenation index value do not change dramatically after ventilation or surfactant administration in LPT infants with RDS compared to very preterm infants. These finding may indicate a different pathogenesis of RDS in late preterm and term infants. In conclusion, surfactant therapy may be of significant benefit in LPT infants with serious respiratory failure secondary to a number of insults. However, optimal timing and dose of administration are not so clear in this group. Additional

    Developmental care has been broadly applied to identify the behavioral cues and care needs of preterm infants. Past studies indicate a significantly higher level of physical distress in bottle-fed preterm infants than in preterm infants who are breastfed. However, no evidence has yet been reported that supports the influence of feeding methods on behavioral cues. This study compares differences in the type and frequency of behavioral cues between breast- and bottle-fed preterm infants. A comparison study design and secondary data analysis method were used to assess data from two previous research projects. Infant feeding behavioral cues were observed and compared between two groups: 7 preterm infants who were breastfed and 7 preterm infants who were bottle-fed. After cases were matched by infant gestational age, behavioral responses were coded according to the preterm feeding cues coding system (PFCCS) from 7 paired maternal-infant feeding videos that featured preterm infants of 25 to 32 weeks gestational age at birth. The PFCCS classifies 24 feeding behavioral cues into hunger cues, self-regulatory cues, stress cues, and satiety cues. Infants in the breastfeeding group had a higher hunger cue frequency than their bottle-fed peers (p = .013), while bottle-fed infants had a higher stress cue frequency than their breastfed peers (p = .041). Other significant differences in behavioral cues between the two feeding methods included "fluid spillage" (bottle- >breast-, p = .008), "central cyanosis" (bottle- >breast-, p = .024) and "hand pushing" (breast- >bottle-, p = .034). Preterm infants in this study who breastfed showed significantly fewer stress cues than those who bottle fed. These findings support the importance of enhancing care provider sensitivity with regard to behavioral-cue observation. Findings further support breastfeeding rather than bottle-feeding for preterm infants.

    To systematically examine gross motor development in the first 18 months of life of preterm infants. A total of 800 preterm infants (356 boys), ages between 1 and 18 months and corrected for degree of prematurity, were assessed with the use of the Alberta Infant Motor Scale. Comparison of the mean Alberta Infant Motor Scale scores of the preterm infants with the norm-referenced values derived from term infants revealed that as a group, the preterm infants scored significantly lower at all age levels, even with full correction for degree of prematurity. In general, preterm infants exhibit different gross motor developmental trajectories compared with term infants in the first 18 months of life. The gross motor developmental profile of preterm infants may reflect a variant of typical gross motor development, which seems most likely to be specific for this population. As a consequence, adjusted norms should be used for proper evaluation and clinical decision-making in relation to preterm infants.

    This study evaluated the effect of infant massage on anxiety in mothers of preterm infants who discharged from the neonatal intensive care unit. Birth of preterm infants commonly leads to great levels of distress and anxiety in mothers. Although various methods have been suggested to help mothers cope with such stressful conditions, the effects of infant massage have not been adequately studied in mothers. This was a quasi-experimental clinical trial. Overall, in 70 mothers and their preterm infants who scheduled to be discharged within 24 hours, State-Trait Anxiety Inventory scale (Spielberger) was completed for mothers in both groups in the morning of the day before discharge. The experimental group received eight minutes of massage including two standard similar parts (each part four minutes). The massage was repeated in two parts on the day of discharge, and then, state anxiety was re-measured using Spielberg's scale for all mothers. The control group received no intervention. The results showed that on the day of discharge, there was a significant difference in the overall mean score of maternal state anxiety between the two groups (p anxiety. In both groups, the mean score of maternal state anxiety was significantly decreased on the day of discharge (p anxiety of mothers of preterm infants, so it is recommended that mothers apply massage for preterm infants to improve their mental health.

    Full Text Available Postnatal adaptation in preterm newborn comprises complex physiological processes that involve significant changes in the circulatory and respiratory system. Increasing hemoglobin level and blood volume following placental transfusion may be of importance in enhancing arterial oxygen content, increasing cardiac output, and improving oxygen delivery. The European consensus on resuscitation of preterm infants recommends delayed cord clamping (DCC for at least 60 s to promote placenta–fetal transfusion in uncompromised neonates. Recently, published meta-analyses suggest that DCC is associated with fewer infants requiring transfusions for anemia, a lower incidence of intraventricular hemorrhage, and lower risk for necrotizing enterocolitis. Umbilical cord milking (UCM has the potential to avoid some disadvantages associated with DCC including the increased risk of hypothermia or delay in commencing manual ventilation. UCM represents an active form of blood transfer from placenta to neonate and may have some advantages over DCC. Moreover, both methods are associated with improvement in hemodynamic parameters and blood pressure within first hours after delivery compared to immediate cord clamping. Placental transfusion appears to be beneficial for the preterm uncompromised infant. Further studies are needed to evaluate simultaneous placental transfusion with resuscitation of deteriorating neonates. It would be of great interest for future research to investigate advantages of this approach further and to assess its impact on neonatal outcomes, particularly in extremely preterm infants.

    Neonatal EEG sleep was used to determine if differences are expressed between healthy late preterm and full term groups. Twenty-seven 24-channel multi-hour studies were recorded at similar post–menstrual ages (PMA) and analyzed for eight asymptomatic late preterm infants (LPT) compared with nineteen healthy full term (FT) infants as a preliminary analysis, followed by a comparison of a subset of 8 FT infants, matched for gender, race, and PMA. Z scores were performed on data sets from each group pair comparing each of seven EEG/Sleep measures for entire recordings, active (AS) and quiet sleep (QS) segments and artifact-free intervals. Six of seven measures showed differences between the 8 LPT and 8 matched FT cohort pair comparisons of >0.3; REMs, arousals during QS, spectral correlations between homologous centro-temporal regions during QS, spectral beta/alpha power ratios during AS and QS, a spectral measure of respiratory regularity during QS, and sleep cycle length. Quantitative neurophysiologic analyses define differences in brain maturation between LPT and FT infants at similar PMA. Altered EEG/Sleep behaviors in the LPT are biomarkers of developmental neuroplasticity involving interconnected neuronal networks adapting to conditions of prematurity for this largest segment of the preterm neonatal population.

    Premature babies require supplementation with calcium (Ca) and phosphorus (P) to prevent metabolic bone disease of prematurity. To guide mineral supplementation, 2 methods of monitoring urinary excretion of Ca and P are used: urinary Ca or P concentration and Ca/creatinine (Crea) or P/Crea ratios. We compare these 2 methods in regards to their agreement on the need for mineral supplementation. Retrospective chart review of 230 premature babies with birth weight urine Ca or P concentration (1 mmol/L) and urine Ca/Crea ratio (0.5 mol/mol) or P/Crea ratio (4 mol/mol) were applied to the sample results. The agreement on whether to supplement the respective minerals based on the results with the 2 methods was compared. Multivariate general linear models sought to identify patient characteristics to predict discordant results. A total of 24.8% of cases did not agree on the indication for Ca supplementation, and 8.8% for P. Total daily Ca intake was the only patient characteristic associated with discordant results. With the intention to supplement the respective mineral, comparison of urinary mineral concentration with mineral/Crea ratio is moderate for Ca and good for P. The results do not allow identifying superiority of either method on the decision as to which babies require Ca and/or P supplements.

    The gastrointestinal structure, function and immunity of preterm infants are immature. Furthermore the gastrointestinal microbe colonization is abnormal. Therefore the preterm infants are prone to a variety of gastrointestinal diseases. Probiotics can regulate gastrointestinal microbe constitute, improve gastrointestinal barrier function, reduce gastrointestinal inflammation response and regulate the immunity. At present, it is used for the prevention of necrotizing enterocolitis, late-onset sepsis, and feeding intolerance. The safety and efficacy of probiotics for preterm infants are still controversial.

    Near Infrared Spectroscopy (NIRS) has been proposed as a useful, noninvasive monitoring technique providing reliable information about central nervous system (CNS) oximetry and function. Recently, brain damage has been reconsidered as a dynamic process evolving over the weeks of gestation. We therefore investigated NIRS cerebral pattern differences between healthy late preterm infants (LPTo) and very preterm infants becoming late preterm (LPT). We conducted an observational study in 40 healthy late preterm infants, matched for gestational age at monitoring, of whom 20 where LPTo and 20 LPT. Clinical, diagnostic and laboratory monitoring procedures and cerebral oximetry (crSO 2 ) and function (cFTOE) were recorded on admission into the study.

    Recurrent apnea is common in preterm infants, particularly at very early gestational ages. These episodes of loss of effective breathing can lead to hypoxemia and bradycardia which may be severe enough to require resuscitation including use of positive pressure ventilation. Doxapram has been used to stimulate breathing and so prevent apnea and its consequences. In preterm infants with recurrent apnea, does treatment with Doxapram lead to a clinically important reduction in apnea and use of intermittent positive airways pressure (IPPV), without clinically important side effects? Searches were made of the Oxford Database of Perinatal trials, the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 3, 2004), MEDLINE from 1966 - June 2004, EMBASE from 1980 - June 2001, CINAHL from 1982- June 2004. Text words 'doxapram', 'apnea or apnoea' and the MeSH term 'infant, premature' were used. Previous reviews including cross references, abstracts from conferences and symposia proceedings were also examined. Abstracts of the Society for Pediatric Research were searched from 1996 - 2004 inclusive. All trials utilising random or quasi-random patient allocation, in which doxapram was used for the treatment of apnea in preterm infants were included. Each author evaluated the papers for quality and inclusion criteria. Independent data extraction was carried out. Only one trial, which randomized 11 infants to intravenous doxapram and 10 infants to placebo, was found. There were fewer treatment failures after 48 hours in the group of preterm infants treated with doxapram (4/11) compared with the group treated with placebo (8/10). The wide confidence intervals made this result non-significant [RR 0.45 (0.20, 1.05)]. Only one infant, who was from the placebo group, was given IPPV. Of the seven responders by 48 hours in the group of 11 who received doxapram, five failed to respond between 48 hours and seven days after commencement of therapy. This gives a

    Common neurologic morbidities encountered in very preterm and extremely preterm infants (intracranial hemorrhage, white matter injury and periventricular leukomalacia, and apnea of prematurity) are much less common in moderately preterm and late preterm infants. The frequency of germinal matrix hemorrhage-intraventricular hemorrhage and white matter injury are reported to be low, but selection bias in neuroimaging surveillance prevents ascertainment of precise frequencies. The major neurologic morbidity of moderately and late preterm infants is feeding difficulty reflecting developmental integration of suck, swallow, and breathing. Copyright © 2013 Elsevier Inc.

    The American Academy of Pediatrics (AAP) has recommended that nutritional management of the preterm infant should aim to achieve body composition that replicates the in utero fetus, but intrauterine body composition reference charts for preterm infants are lacking. Our objective was to create body composition reference curves for preterm infants that approximate the body composition of the in utero fetus from 30 to 36 wk of gestation. A total of 223 ethnically diverse infants born at 30 + 0 to 36 + 6 wk of gestation were enrolled. Inclusion and exclusion criteria were specified so that the sample would represent healthy appropriately growing fetuses (e.g., singleton, birth weight appropriate for their gestational age, and medically stable). Cross-sectional reference values were generated for fat mass (FM), fat-free mass (FFM), and percentage body fat (PBF) by gestational age (GA), with the use of air-displacement plethysmography (ADP) and the lambda-mu-sigma method for percentile estimation. GA-specific percentile values and a percentile and z score calculator for FFM, FM, and PBF are presented. These values aligned closely with ADP centile values published for term infants from 36 to 38 wk of gestation. The medians were also similar to the mean values for the reference fetus derived from chemical analysis previously. To our knowledge, these are the first body composition reference charts for total FM and FFM at birth in preterm infants to assist in following AAP guidelines. Future work will test the clinical utility of body composition monitoring for improving nutritional management in this population.

    Weaning and extubating preterm infants on intermittent positive pressure ventilation (IPPV) for respiratory failure may be difficult. A significant contributing factor is thought to be the relatively poor respiratory drive and tendency to develop hypercarbia and apnoea, particularly in very preterm infants. Methylxanthine treatment started before extubation might stimulate breathing and increase the chances of successful weaning from IPPV. To determine the effects of prophylactic methylxanthine treatment on the use of intubation and IPPV and other clinically important side effects in preterm infants being weaned from IPPV and in whom endotracheal extubation is planned. The standard search strategy of the Cochrane Neonatal Review Group was used. This included searches of The Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 2, 2010), the Oxford Database of Perinatal Trials, MEDLINE (1966 to July 2010), CINAHL (1982 to July 2010) and EMBASE (1988 to July 2010). All published trials utilising random or quasi-random patient allocation in which treatment with methylxanthines (theophylline or caffeine) was compared with placebo or no treatment to improve the chances of successful extubation of preterm or low birth weight infants were included. The standard methods of the Cochrane Collaboration and its Neonatal Review Group were used. Seven studies were identified for inclusion. Methylxanthine treatment results in a reduction in failure of extubation within one week (summary RR 0.48, 95%CI 0.32 to 0.71; summary RD -0.27, 95%CI -0.39 to -0.15; NNT 4, 95%CI 3 to 7; six trials, 172 infants). There is significant heterogeneity in the RD meta-analysis perhaps related to the large variation in baseline rate in the control groups (range 20 to 100%).The CAP trial enrolled the largest number of infants, but did not report extubation rates. In the caffeine group, there were lower rates of bronchopulmonary dysplasia, PDA ligation, cerebral palsy

    Absence of guidelines on umbilical arterial catheter (UAC) and umbilical venous catheter (UVC) use and inability to predict the hospital course may sway the frontline staff to overuse umbilical catheters in preterm infants. Our objective was to evaluate the feasibility of implementing guidelines standardizing the use of umbilical catheters and its impact on the incidence of sepsis and resource use. All inborn infants delivered at <33 weeks' gestation and admitted to the NICU were included in this quality improvement study. The primary outcome was proportion of infants receiving umbilical catheters. Secondary outcomes were central venous catheter (CVC) use and central line-associated bloodstream infection (CLABSI). The proportion of infants receiving UACs and UVCs was significantly lower in postintervention (sustainment) phase than in the preintervention phase (93 [42.3%] vs 52 [23.6%], P = .0001) and (137 [62.6%] vs 93 [42.3%], P = .0001), respectively. There was no corresponding increase in the proportion of infants receiving peripherally inserted central catheters (PICCs) or surgical CVCs (SCVCs) during the sustainment phase. There was a significant reduction in the proportion of infants receiving CVCs (UVC, PICC, and SCVC) in the sustainment phase. The incidence of CLABSI was similar in the preintervention and sustainment phases. Implementation of guidelines standardizing the use of umbilical catheters in the NICU is feasible. Fewer infants were exposed to the risk of UVC or UAC, and fewer resources were used. Copyright © 2014 by the American Academy of Pediatrics.

    Full Text Available Aim: To determine how accurately the daily prescribed feed volume (mL/day estimates the actual intake of breastfeeding preterm infants and to characterise the volume taken during a breastfeed at differing gestational and postmenstrual ages. Methods: A cross sectional study was conducted on preterm infants born <37 weeks gestation from two Australian neonatal units. To determine the volume taken in a 24-h period infants were weighed before and after each breastfeed. This volume was added to the charted intake to determine the total intake and then compared to the prescribed feed volume. Bland Altman analyses were used to assess the level of agreement between the two methods. Results: Fifty six infants were studied on 206 breastfeeding occasions. There was a small bias (27 mLs/day but large 95% limits of agreement (–76 to 130 mL/day. The volume taken during a single breastfeed ranged from 0 to 101 mL (median 23 mL, IQR 9 to 31 mL and was greater in more mature infants. Conclusions: Using the prescribed feed volume to estimate total intake has limited clinical utility for the individual infant, however the relatively small bias means that it may be useful within a population or for comparison between groups in which population means are compared. There was a large variation in volume taken during a breastfeed across all gestational and postmenstrual ages.

    As survival rates for preterm infants improve, more attention is being focused on improving the quality of survival through optimal nutritional management. The benefits of human milk for term infants are well recognized, with current research suggesting that human milk may especially benefit the preterm infant. Some mothers are unable or unwilling to provide breastmilk for their infants. Although not as well studied as mother's own milk, pasteurized donor human milk can provide many of the components and benefits of human milk while eliminating the risk of transmission of infectious agents. Pasteurization does affect some of the nutritional and immunologic components of human milk, but many immunoglobulins, enzymes, hormones, and growth factors are unchanged or minimally decreased. In California donor human milk costs approximately $3.00 per ounce to purchase. A reduction in length of stay, necrotizing enterocolitis and sepsis may result in a relative saving of approximately $11 to the NICU or healthcare plan for each $1 spent for pasteurized donor milk.

    Preterm birth is a global public health problem that is a significant cause of infant morbidity and mortality. Congenital cytomegalovirus (CMV) infection has been proposed as a risk factor for preterm birth, but the rate of CMV in infants born preterm is unclear. CMV is the leading infectious cause of sensorineural hearing loss, which will affect 15% - 20% of congenitally infected infants later in their childhood. 90% of infected infants are asymptomatic at birth and are not recognized as at risk for CMV-associated deficits. To determine the prevalence of CMV infection in a large cohort of preterm infants. DNA was extracted from cord blood, peripheral blood, saliva, and buccal swab samples collected from preterm infants. A total of 1200 unique DNA samples were tested for CMV using a nested PCR protocol. The proportions of preterm infants with CMV was compared by sample collection type, race, gender, and gestational age. A total of 37 infants tested positive for CMV (3.08%). After excluding twins, siblings, and infants older than two weeks at the time of sample collection, two out of 589 infants were CMV positive (0.3%), which was lower than the proportion of CMV observed in the general population. All positive samples came from buccal swabs. Our work suggests that while CMV infection may not be greater in preterm infants than in the general population, given the neurologic consequences of CMV in preterm infants, screening of this population may still be warranted. If so, our results suggest buccal swabs, collected at pregnancy or at birth, may be an ideal method for such a program.

    Full Text Available Background: Surfactant replacement therapy (SRT is an integral part of management of preterm surfactant deficiency (respiratory distress syndrome, RDS. Its role in the management of RDS has been extensively studied. However its efficacy in the management of lung disease in preterm infants born with intrauterine growth restriction (IUGR has not been systematically studied.Objective: To evaluate the efficacy of exogenous surfactant replacement therapy in the management of preterm IUGR lung disease. Methods: A systematic search of all available randomised clinical trials (RCT of surfactant replacement therapy in preterm IUGR infants was done according to the standard Cochrane collaboration search strategy. Neonatal respiratory outcomes were compared between the preterm IUGR and appropriately-grown for gestational age (AGA preterm infant populations in eligible studies. Results: No study was identified which evaluated the efficacy or responsiveness of exogenous surfactant replacement therapy in preterm IUGR infants as compared to preterm AGA infants. The only study identified through the search strategy used small for gestational age (SGA; defined as less than 10th centile for birth weight as a proxy for IUGR. The RCT evaluated the efficacy or responsiveness of SRT in preterm SGA group as compared to AGA infants. The rate of intubation, severity of RDS, rate of surfactant administration, pulmonary air leaks and days on the ventilator did not differ between both groups. However, the requirement for prolonged nasal CPAP (p< 0.001, supplemental oxygen therapy (p <0.01 and the incidence of bronchopulmonary dysplasia at 28 days and 36 weeks (both p<0.01 was greater in SGA infants. Discussion: There is currently insufficient data available to evaluate the efficacy of SRT in preterm IUGR lung disease. A variety of research strategies will be needed to enhance our understanding of the role and rationale for use of surfactant replacement therapy in preterm

    The authors aimed to investigate proximal and distal adjustments of reaching behavior and grasping in 5-, 6-, and 7-month-old preterm infants. Nine low-risk preterm and 10 full-term infants participated. Both groups showed the predominance of unimanual reaching, an age-related increase in the frequency of vertical-oriented and open hand movement, and also an increase in successful grasping from 6 to 7 months. The frequency of open hand was higher in the preterm group at 6 months. Intrinsic restrictions imposed by prematurity did not seem to have impaired reaching performance of preterm infants throughout the months of age.

    2013-06-01

    Full Text Available Despite of improved survival of premature infants, the incidence of long term pulmonary complications, mostly associated with ventilation-induced lung injury, remains high. Non invasive ventilation (NIV is able to reduce the adverse effects of mechanical ventilation. Although nasal continuous positive airway pressure (NCPAP is an effective mode of NIV, traumatic nasal complications and intolerance of the nasal interface are common. Recently high flow nasal cannula (HFNC is emerging as an efficient, better tolerated form of NIV, allowing better access to the baby’s face, which may improve nursing, feeding and bonding. The aim of this review is to discuss the available evidence of effectiveness and safety of HFNC in preterm newborns with respiratory distress syndrome (RDS. It is known that distending pressure generated by HFNC increases with increasing flow rate and decreasing infant size and varies according to the amount of leaks by nose and mouth. The effects of HFNC on lung mechanics, its clinical efficacy and safety are still insufficiently investigated. In conclusion, there is a growing evidence of the feasibility of HFNC as an alternative mode of NIV. However, further larger randomized trials are required, before being able to recommend HFNC in the treatment of moderate respiratory distress of preterm infants.

    Full Text Available Background. Improved perinatal care has increased the survival rate of prematurely born infants. An epidemiological fact that 6–18% and more visually impaired children were prematurely born, emphasises the effect of premature birth on both visual function and development. Despite better knowledge on retinopathy of prematurity (ROP it is stressed not to underestimate refractive errors, strabismus and visual impairment after brain lesions, being more common in preterm babies.Methods. Over 1300 preterm infants with a birth weight of 1500 g or less and gestational age of 30 weeks or less, born in Maternity Hospital of Ljubljana, Slovenia in the period 1990– 1999 were examined according to contemporary paediatricophthalmologic recommendations. At least one year ophthalmologic follow-up (average 3.5 years of 594 prematurely born infants with high neonatal risk factors for ROP and with general health problems, was performed. Sex, gestational age, birth weight, artificial ventilation, exchange blood transfusion, bronchopulmonary dysplasia, respiratory distress syndrome, apnoea, septicaemia, intraventricular haemorrhage, hyperbilirubinemia were analysed for correlation with ROP and visual impairment.Results. The survival rate of the studied preterm infants was 65–87% (mean 77.3%. ROP stage 1, 2 has developed in 33 children with a birth weight under 900 g and in 10 with a birth weight 900–1200 g (altogether in 8%.

    Preterm infants are at risk of exhausting their body iron stores much earlier than healthy term newborns. It is widespread practice to give enteral iron supplementation to preterm and low birth weight infants to prevent iron deficiency anaemia. However, it is unclear whether supplementing preterm and low birth weight infants with iron improves growth and neurodevelopment. It is suspected that excess exogenous iron can contribute to oxidative injury in preterm babies, causing or exacerbating conditions such as necrotising enterocolitis and retinopathy of prematurity. Additionally, the optimal dose and timing of commencement and cessation of iron supplementation are uncertain. To evaluate the effect of prophylactic enteral iron supplementation on growth and neurodevelopmental outcomes in preterm and low birth weight infants. The secondary objectives were to determine whether iron supplementation results in improved haematological parameters and prevents other causes of morbidity and mortality. We used the standard search strategy of the Cochrane Neonatal Review Group. We searched Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 8), MEDLINE (1951 to August 2011), CINAHL (1982 to August 2011) and conference proceedings and previous reviews. Randomised controlled trials (RCTs) and quasi-randomised trials that compared enteral iron supplementation with no iron supplementation, or different regimens of enteral iron supplementation in preterm or low birth weight infants or both. We extracted data using the standard methods of the Cochrane Neonatal Review Group. Both review authors separately evaluated trial quality and data extraction. We synthesised data using risk ratios (RRs), risk differences (RDs) and weighted mean differences (WMDs). Where data about the methodology and results or both were lacking, we made an attempt to contact the study authors for further information. We included twenty-six studies (2726 infants) in the

    In response to a national shortage of parenteral phosphorus solutions (2013), a hospital-wide phosphorus dose restriction strategies was implemented which included judicious use of phosphorus in preterm infants birth weight and no parenteral phosphorus in preterm infants >1250 g birth weight unless they have a critically low phosphorus level. To study the effect of parenteral phosphorus dose restriction in preterm infants admitted to the neonatal intensive care unit. Preterm infants (≤35 weeks birth gestation and ≤2500 g birth weight) who received parenteral nutrition, survived >1 week and had no major congenital anomalies were studied. Clinical and laboratory data in the first 4 weeks of life of infants admitted during the parenteral phosphorus shortage (cases) were compared to infants who were admitted 6 months prior to the shortage (controls). Twenty consecutive cases were compared to 40 consecutive controls. Cases had lower serum phosphorus levels, higher serum alkaline phosphatase levels, and need for greater inotropic support compared to controls. These differences were significant only in preterm infants with birth weight >1250 g, the group who received more parenteral phosphorus dose restriction while they were similar in preterm infants with birth weight <1250 g. The modest effects of phosphorus dose restriction may become more clinically important if shortage is prolonged or severe or if it involves extreme preterm infants.

  19. Intravenous Lipids for Preterm Infants: A Review

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Extremely low birth weight infants (ELBW are born at a time when the fetus is undergoing rapid intrauterine brain and body growth. Continuation of this growth in the first several weeks postnatally during the time these infants are on ventilator support and receiving critical care is often a challenge. These infants are usually highly stressed and at risk for catabolism. Parenteral nutrition is needed in these infants because most cannot meet the majority of their nutritional needs using the enteral route. Despite adoption of a more aggressive approach with amino acid infusions, there still appears to be a reluctance to use early intravenous lipids. This is based on several dogmas that suggest that lipid infusions may be associated with the development or exacerbation of lung disease, displace bilirubin from albumin, exacerbate sepsis, and cause CNS injury and thrombocytopena. Several recent reviews have focused on intravenous nutrition for premature neonate, but very little exists that provides a comprehensive review of intravenous lipid for very low birth and other critically ill neonates. Here, we would like to provide a brief basic overview, of lipid biochemistry and metabolism of lipids, especially as they pertain to the preterm infant, discuss the origin of some of the current clinical practices, and provide a review of the literature, that can be used as a basis for revising clinical care, and provide some clarity in this controversial area, where clinical care is often based more on tradition and dogma than science.

    Methods are needed to evaluate the level of early motor development and quality of motor performance in infants. We examined the convergent and discriminant validity of the Structured Observation of Motor Performance in Infants (SOMP-I) for evaluating the level of motor development and quality of motor performance in preterm and term infants. A regional cohort of 111 preterm infants with a gestational age of validity was analysed with a mixed model analysis of the motor performance over time. Discriminant validity was analysed with the Mann-Whitney U-test in groups with different neonatal characteristics. Convergent validity was supported, as the level of motor development increased with age and the quality of motor performance improved over time. The method discriminated for both level and quality between the preterm and the term infants. The preterm infants demonstrated different quality deficits regardless of the level of motor development. Convergent validity and discriminant validity of the SOMP-I were supported in preterm and term infants and facilitates early identification of infants with atypical motor development. ©2017 Foundation Acta Paediatrica.

    Iron deficiency anemia is a common problem in newborn infants. The American Academy of Pediatrics recommends iron prophylaxis at 4 months of age for term infants. There is no specific recommendation for iron prophylaxis in late-preterm infants. We aimed to establish the optimum time for iron prophylaxis in late-preterm infants. Thirty-eight late-preterm (Group 1) and 38 term (Group 2) infants born on the same day were enrolled in the study. Hemoglobin, ferritin and reticulocyte values at birth, 2nd month and 4th month were assessed. The cord ferritin, hemoglobin and reticulocyte levels did not differ significantly between groups. However, at the 2nd month, median ferritin and hemoglobin values were lower in late-preterm infants than term infants (145 mg/dl vs. 195 mg/dl, p=0.001 and 10.1 g/dl vs. 11.6 g/dl, pinfants than term infants, but this difference was not significant after exclusion of three late- preterm infants who required iron therapy (49 mg/dl vs. 62 mg/dl, p=0.2). There was a tendency of higher frequency of anemia in late-preterm infants at 4 months (42.8% vs. 21.1%), but this was statistically insignificant (p=0.07). At the 2nd month of age, the median ferritin and hemoglobin levels of late-preterm infants were lower than those of term infants. Further studies with larger sample sizes are required to determine the need for earlier supplementation of iron in late-preterm infants.

    To compare developmental outcomes of late preterm infants (34-36 weeks' gestation) with infants born at early term (37-38 weeks' gestation) and term (39-41 weeks' gestation), from infancy through kindergarten. Sample included 1000 late preterm, 1800 early term, and 3200 term infants ascertained from the Early Childhood Longitudinal Study, Birth Cohort. Direct assessments of development were performed at 9 and 24 months by using the Bayley Short Form-Research Edition T-scores and at preschool and kindergarten using the Early Childhood Longitudinal Study, Birth Cohort reading and mathematics θ scores. Maternal and infant characteristics were obtained from birth certificate data and parent questionnaires. After controlling for covariates, we compared mean developmental outcomes between late preterm and full-term groups in serial cross-sectional analyses at each timepoint using multilinear regression, with pairwise comparisons testing for group differences by gestational age categories. With covariates controlled at all timepoints, at 9 months late preterm infants demonstrated less optimal developmental outcomes (T = 47.31) compared with infants born early term (T = 49.12) and term (T = 50.09) (P kindergarten reading (P = .0007) compared with infants born at term gestation. Although late preterm infants demonstrate comparable developmental outcomes to full-term infants (early term and full-term gestation) at 24 months, they demonstrate less optimal reading outcomes at preschool and kindergarten timepoints. Ongoing developmental surveillance for late preterm infants is warranted into preschool and kindergarten. Copyright © 2016 by the American Academy of Pediatrics.

    Full Text Available Background The pathogenesis of bronchopulmonary dysplasia (BPD is multifactorial. In addition to prenatal inflammation, postnatal malnutrition also affects lung development. Methods A retrospective study was performed to analyse during the first two weeks of life the total, enteral and parenteral nutrition of premature infants ( Results Ninety-five premature infants were analysed: 26 with BPD (27 ± 1 weeks and 69 without BPD (28 ± 1 weeks. There was no statistical significant difference in the total intake of fluids, calories, glucose or protein and weight gain per day in both groups. The risk of developing BPD was slightly increased in infants with cumulative caloric intake below the minimal requirement of 1230 kcal/kg and a cumulative protein intake below 43.5 g/kg. Furthermore, the risk of developing BPD was significantly higher when infants had a cumulative fluid intake above the recommended 1840 ml/kg. In infants who developed BPD, the enteral nutrition was significantly lower than in non-BPD infants [456 ml/kg (IQR 744, 235 vs. 685 (IQR 987, 511]. Infants who did not develop BPD reached 50% of total enteral feeding significantly faster [9.6 days vs. 11.5]. Conclusions Preterm infants developing BPD received less enteral feeding, even though it was well compensated by the parenteral nutrient supply. Data suggest that a critical minimal amount of enteral feeding is required to prevent development of BPD; however, a large prospective clinical study is needed to prove this assumption.

    The importance of early life events in the development of metabolic diseases is well recognized. Early postnatal environment, including nutrition, is key to future health, and this is particularly true for preterm infants. It is important that these infants receive sufficient nutrients to prevent growth restriction and promote neurodevelopment, while minimizing predisposition to metabolic diseases later in life. Feeding habits are the fundamental elements of nutrition and are influenced by many factors, including personal and familial habits, socioeconomic status, and cultural environment. In the last decades, there has been an important scientific interest toward the comprehension of the molecular and neural mechanisms regulating appetite. In these networks, act many peptide hormones produced in brain or gut, among which ghrelin is important because of its action in the short-term regulation of food intake and the long-term regulation of body weight. Ghrelin stimulates appetite and plays a role in regulating feeding behaviour. Ghrelin levels vary from fetal life through to early adulthood, with the highest levels observed in the very early years. Cord ghrelin levels have been evaluated in term and preterm newborns and high ghrelin levels have been observed in small-for-gestational age newborns and in newborns with intrauterine growth restriction. Moreover, ghrelin has been detected in term and preterm human breast milk, suggesting that it may play a role in the development of neuroendocrine pathways regulating appetite and energy homeostasis in early life. However, more research is required to better define ghrelin's role in breast milk and on feeding behaviour. Copyright © 2011 Elsevier Ltd. All rights reserved.

  8. Cerebral hypoxia and ischemia in preterm infants

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Premature birth is a major public health issue internationally affecting 13 million babies worldwide. Hypoxia and ischemia is probably the commonest type of acquired brain damage in preterm infants. The clinical manifestations of hypoxic-ischemic injury in survivors of premature birth include a spectrum of cerebral palsy and intellectual disabilities. Until recently, the extensive brain abnormalities in preterm neonates appeared to be related mostly to destructive processes that lead to substantial deletion of neurons, axons, and glia from necrotic lesions in the developing brain. Advances in neonatal care coincide with a growing body of evidence that the preterm gray and white matter frequently sustain less severe insults, where tissue destruction is the minor component. Periventricular leukomalacia (PVL is the major form of white matter injury and consists classically of focal necrotic lesions, with subsequent cyst formation, and a less severe but more diffuse injury to cerebral white mater, with prominent astrogliosis and microgliosis but without overt necrosis. With PVL a concomitant injury occurs to subplate neurons, located in the subcortical white matter. Severe hypoxic-ischemic insults that trigger significant white matter necrosis are accompanied by neuronal degeneration in cerebral gray and white matter. This review aims to illustrate signs of cerebral embryology of the second half of fetal life and correlate hypoxic-ischemic brain injury in the premature infant. This should help us better understand the symptoms early and late and facilitate new therapeutic strategies. Proceedings of the International Course on Perinatal Pathology (part of the 10th International Workshop on Neonatology · October 22nd-25th, 2014 · Cagliari (Italy · October 25th, 2014 · The role of the clinical pathological dialogue in problem solving Guest Editors: Gavino Faa, Vassilios Fanos, Peter Van Eyken

    To take a systematic approach to reviewing the scientific literature examining the timeliness of vaccination in preterm infants and to identify any factors associated with timeliness. Preterm infants are vulnerable to infection and guidance advocates they are vaccinated in accordance with their full-term peers. Vaccination is well tolerated and protective immune responses are observed, yet some early enquiries suggest that preterm infants experience unwarranted delays. The recent surge in pertussis cases and the increase in vaccinations administered make this a topic requiring further exploration. An integrative review of the empirical literature. Studies were identified following a search of Medline, Academic Search Premier, Cochrane Database of Systematic Reviews and the Cumulative Index to Nursing and Allied Health Literature. The review methods used were influenced by a narrative synthesis approach. The retrieval of papers adhered to recognised reporting standards. Fourteen studies were identified, which indicated that infants with the lowest gestational ages and birthweights experience the greatest delays. Vaccination timeliness is influenced by hospitalisation and increased postdischarge follow-up. There was a lack of consensus to indicate that parental socio-economic status and level of education were indicators for a delay. The studies propose that many delays are unjustified and not according to genuine contraindications. This review indicates that preterm infants are not vaccinated in a timely manner. Those involved in vaccinating preterm infants must be informed of the genuine contraindications to avoid unnecessary delays putting preterm infants at an increased risk of infection. Care providers should acknowledge the risk of a delay in preterm infants and actively promote vaccination in this population. Regular training should help to negate the occurrence of inappropriate delays, and careful discharge planning is needed to ensure that preterm infants

    2005-11-01

    Full Text Available Abstract Background The increased survival of preterm and very low birth weight infants in recent years has been well documented but continued surveillance is required in order to monitor the effects of new therapeutic interventions. Gestation and birth weight specific survival rates most accurately reflect the outcome of perinatal care. Our aims were to determine survival to discharge for a large Canadian cohort of preterm infants admitted to the neonatal intensive care unit (NICU, and to examine the effect of gender on survival and the effect of increasing postnatal age on predicted survival. Methods Outcomes for all 19,507 infants admitted to 17 NICUs throughout Canada between January 1996 and October 1997 were collected prospectively. Babies with congenital anomalies were excluded from the study population. Gestation and birth weight specific survival for all infants with birth weight Results Survival to discharge at 24 weeks gestation was 54%, compared to 82% at 26 weeks and 95% at 30 weeks. In infants with birth weights 600–699, survival to discharge was 62%, compared to 79% at 700–799 g and 96% at 1,000–1,099 g. In infants born at 24 weeks gestational age, survival was higher in females but there were no significant gender differences above 24 weeks gestation. Actuarial analysis showed that risk of death was highest in the first 5 days. For infants born at 24 weeks gestation, estimated survival probability to 48 hours, 7 days and 4 weeks were 88 (CI 84,92%, 70 (CI 64, 76% and 60 (CI 53,66% respectively. For smaller birth weights, female survival probabilities were higher than males for the first 40 days of life. Conclusion Actuarial analysis provides useful information when counseling parents and highlights the importance of frequently revising the prediction for long term survival particularly after the first few days of life.

    The rehospitalization rate of preterm infants is between 22 and 52% within the first year after discharge. The purpose of this study was to investigate the rehospitalization of preterm infants within 2 months following discharge, considering the level of risks originating from the infant, parents, and the social factors. The sample was composed of 238 preterm infants and their parents. The data were collected with a Descriptive Information Form, the Post-Discharge Infant Follow-up Form, and the Neonatal Discharge Assessment Tool (N-DAT). Before discharge, the preterm infants were evaluated in terms of risky discharge via N-DAT consisting of the subscales Medical, Competencies, Risk factors, Resources, and Parenting. Discharge was determined as low, moderate, and high risk according to N-DAT total score. Two months after the discharge, rehospitalization of the infants was assessed. The data were evaluated via chi-square, Mann-Whitney U-test, and Fisher's exact test. In the study, 39.9% of the preterm infants were rehospitalized within the 8 weeks following the discharge, with medical and/or surgical reasons. Medical problems such as pneumonia and acute bronchiolitis were ranked as the first cause for rehospitalization. As expected, according to the N-DAT scores, the rates of rehospitalization of infants who had been discharged with intermediate and high risk levels were found to be higher (p Nurses can help to minimize rehospitalization of infants by parental education, telephonic counseling, frequent observation, and home care support. © 2016, Wiley Periodicals, Inc.

    2010-09-01

    Full Text Available Abstract Background In neonatology the role of chest physiotherapy is still uncertain because of the controversial outcomes. Methods The aim of this study was to test the applicability in preterm infants of 'reflex rolling', from the Vojta method, in preterm neonates with lung pathology, with particular attention to the effects on blood gases and oxygen saturation, on the spontaneous breathing, on the onset of stress or pain. The study included 34 preterm newborns with mean gestational age of 30.5 (1.6 weeks - mean (DS - and birth weight of 1430 (423 g - mean (DS -, who suffered from hyaline membrane disease, under treatment with nasal CPAP (continuous positive airways pressure, or from pneumonia, under treatment with oxygen-therapy. The neonates underwent phase 1 of 'reflex rolling' according to Vojta method three times daily. Respiratory rate, SatO2, transcutaneous PtcCO2 e PtcO2 were monitored; in order to evaluate the onset of stress or pain following the stimulations, the NIPS score and the PIPP score were recorded; cerebral ultrasound scans were performed on postnatal days 1-3-5-7, and then weekly. Results In this population the first phase of Vojta's 'reflex rolling' caused an increase of PtcO2 and SatO2 values. No negative effects on PtcCO2 and respiratory rate were observed, NIPS and PIPP stress scores remained unmodified during the treatment; in no patient the intraventricular haemorrhage worsened in time and none of the infants developed periventricular leucomalacia. Conclusions Our experience, using the Vojta method, allows to affirm that this method is safe for preterm neonates, but further investigations are necessary to confirm its positive effects and to evaluate long-term respiratory outcomes.

    Full Text Available PTS symptoms are a common negative emotional response of mothers of preterm infants. PTS symptoms are one of the least explored emotional responses in postpartum period and in mothers of preterm infants. Malawi has the highest preterm birth in the world, but little is known about PTS symptoms following preterm birth in Malawi. The purpose of this paper is to review evidence on the incidence, prevalence, and impact of PTS symptoms following preterm birth, predictors of PTS symptoms, screening and management, and to identify the gaps and the applicability of the evidence to developing countries such as Malawi. A literature search was conducted using PubMed, PsychINFO, CINAHL, and ERIC databases. Articles were limited to PTS symptoms in mothers after preterm birth and up to 24 months. A total of 23 articles were included in the analysis. Findings showed that most literature was from developed countries. Fifteen instruments were identified and the PPQ was the most commonly used instrument. Time points for measurement varied. Mothers of preterm infants presented with at least one PTS symptom and they had higher PTS symptoms than mothers of healthy full-term infants, but no significant differences were seen with mothers of sick full term infants. Maternal, infant, and external factors predicted the onsets of PTS symptoms. Psychoeducation and counseling significantly reduced PTS symptoms, although mothers were only referred if symptoms were severe. Research in developing or low-income countries like Malawi is needed and researchers need to engage more in longitudinal approaches.

    Objective To compare maternal report of planned and practiced home sleep locations of infants born late preterm (34 0/7 to 36 6/7 gestational weeks) with those infants born term (≥ 37 0/7 gestational weeks) over the first postpartum month. Methods Open-ended semi-structured maternal interviews were conducted in a U.S. hospital following birth and by phone at one month postpartum during 2010–2012. Participants were 56 mother-infant dyads: 26 late preterm and 30 term. Results Most women planned to room share at home with their infants and reported doing so for some or all of the first postpartum month. More women reported bed sharing during the first postpartum month than had planned to do so in both the late preterm and term groups. The primary reason for unplanned bed sharing was to soothe nighttime infant fussiness. Those participants who avoided bed sharing at home commonly discussed their fear for infant safety. A few parents reported their infants were sleeping propped on pillows and co-sleeping on a recliner. Some women in both the late preterm and term groups reported lack of opportunity to obtain a bassinet prior to childbirth. Conclusions The discrepancy between plans for infant sleep location at home and maternally reported practices were similar in late preterm and term groups. Close maternal proximity to their infants at night was derived from the need to assess infant well-being, caring for infants, and women’s preferences. Bed sharing concerns related to infant safety and the establishment of an undesirable habit, and alternative arrangements included shared recliner sleep. PMID:25626714

    (1) Background: Late preterm infants account for the majority of preterm births and are at risk of altered body composition. Because body composition modulates later health outcomes and human milk is recommended as the normal method for infant feeding, we sought to investigate whether human milk feeding in early life can modulate body composition development in late preterm infants; (2) Methods: Neonatal, anthropometric and feeding data of 284 late preterm infants were collected. Body composition was evaluated at term-corrected age by air displacement plethysmography. The effect of human milk feeding on fat-free mass and fat mass content was evaluated using multiple linear regression analysis; (3) Results: Human milk was fed to 68% of the infants. According to multiple regression analysis, being fed any human milk at discharge and at  term-corrected and being fed exclusively human milk at term-corrected age were positively associated with fat-free mass content(β = -47.9, 95% confidence interval (CI) = -95.7; -0.18; p = 0.049; β = -89.6, 95% CI = -131.5; -47.7; p Human milk feeding appears to be associated with fat-free mass deposition in late preterm infants. Healthcare professionals should direct efforts toward promoting and supporting breastfeeding in these vulnerable infants.

    Ehmer Ulrike

    2005-10-01

    Full Text Available Abstract Background Well-designed clinical studies on the palatal development in preterm and low birthweight infants are desirable because the literature is characterized by contradictory results. It could be shown that knowledge about 'normal' palatal development is still weak as well (Part 1. The objective of this review is therefore to contribute a fundamental analysis of methodologies, confounding factors, and outcomes of studies on palatal development in preterm and low birthweight infants. Methods An electronic literature search as well as hand searches were performed based on Cochrane search strategies including sources of more than a century in English, German, and French. Original data were recalculated from studies which primarily dealt with both preterm and term infants. The extracted data, especially those from non-English paper sources, were provided unfiltered for comparison. Results Seventy-eight out of 155 included articles were analyzed for palatal morphology of preterm infants. Intubation, feeding tubes, feeding mode, tube characteristics, restriction of oral functions, kind of diet, cranial form and birthweight were seen as causes contributing to altered palatal morphology. Changes associated with intubation concern length, depth, width, asymmetry, crossbite, and contour of the palate. The phenomenon 'grooving' has also been described as a complication associated with oral intubation. However, this phenomenon suffers from lack of a clear-cut definition. Head flattening, pressure from the oral tube, pathologic or impaired tongue function, and broadening of the alveolar ridges adjacent to the tube have been raised as causes of 'grooving'. Metrically, the palates of intubated preterm infants remain narrower, which has been examined up to the age of the late mixed dentition. Conclusion There is no evidence that would justify the exclusion of any of the raised causes contributing to palatal alteration. Thus, early orthodontic and

    Background and Aim Many preterm infants are not capable of exclusive breastfeeding from birth. To guide mothers in breastfeeding, it is important to know when preterm infants can initiate breastfeeding and progress. The aim was to analyse postmenstrual age (PMA) at breastfeeding milestones in different preterm gestational age (GA) groups, to describe rates of breastfeeding duration at pre-defined times, as well as analyse factors associated with PMA at the establishment of exclusive breastfeeding. Methods The study was part of a prospective survey of a national Danish cohort of preterm infants based on questionnaires and structured telephone interviews, including 1,221 mothers and their 1,488 preterm infants with GA of 24–36 weeks. Results Of the preterm infants, 99% initiated breastfeeding and 68% were discharged exclusively breastfed. Breastfeeding milestones were generally reached at different PMAs for different GA groups, but preterm infants were able to initiate breastfeeding at early times, with some delay in infants less than GA 32 weeks. Very preterm infants had lowest mean PMA (35.5 weeks) at first complete breastfeed, and moderate preterm infants had lowest mean PMA at the establishment of exclusive breastfeeding (36.4 weeks). Admitting mothers to the NICU together with the infant and minimising the use of a pacifier during breastfeeding transition were associated with 1.6 (95% CI 0.4–2.8) and 1.2 days (95% CI 0.1–2.3) earlier establishment of exclusive breastfeeding respectively. Infants that were small for gestational age were associated with 5.6 days (95% CI 4.1–7.0) later establishment of exclusive breastfeeding. Conclusion Breastfeeding competence is not developed at a fixed PMA, but is influenced by multiple factors in infants, mothers and clinical practice. Admitting mothers together with their infants to the NICU and minimising the use of pacifiers may contribute to earlier establishment of exclusive breastfeeding. PMID:25251690

    Limited research has been conducted that elucidates the growth and body composition of preterm infants. It is known that these infants do not necessarily achieve extra-utero growth rates and body composition similar to those of their term counterparts. Preterm infants, who have difficulty in achieving these growth rates, could suffer from growth failure. These infants display an increased intra-abdominal adiposity and abnormal body composition when they achieve catch-up growth. These factors affect the quality of weight gain, as these infants are not only shorter and lighter than term infants, they also have more fat mass (FM) and less fat-free mass (FFM), resulting in a higher total fat percentage. This could cause metabolic syndrome and cardiovascular problems to develop later in a preterm infant's life. The methods used to determine body composition in preterm infants should be simple, quick, non-invasive and inexpensive. Available literature was reviewed and the Dauncey anthropometric model, which includes skinfold thickness at two primary sites and nine body dimensions, is considered in this review the best method to accurately determine body composition in preterm infants, especially in resource-poor countries. It is imperative to accurately assess the quality of growth and body composition of this fragile population in order to determine whether currently prescribed nutritional interventions are beneficial to the overall nutritional status and quality of life-in the short- and long-term-of the preterm infant, and to enable timely implementation of appropriate interventions, if required.

    The purpose of this secondary analysis was to determine what factors predict the transition of preterm infants to the supine sleep position prior to hospital discharge (N = 286). The supine position reduces the risk of sudden infant death syndrome. Factors found to predict a greater than 1-week transition to the supine sleep position were hospital policy (P position during hospitalization potentially reduces the risk of preterm infants being placed in nonsupine positions after hospitalization and, ultimately, the risk of untimely death by sudden infant death syndrome.

    Full Text Available OBJECTIVE: To explore the relationship between prematurity, gender and chorioamnionitis as determinants of early life lung function in premature infants. METHODS: Placenta and membranes were collected from preterm deliveries (<37 weeks gestational age and evaluated for histological chorioamnionitis (HCA. Patients were followed and lung function was performed in the first year of life by Raised Volume-Rapid Thoracic Compression Technique. RESULTS: Ninety-five infants (43 males born prematurely (median gestational age 34.2 weeks were recruited. HCA was detected in 66 (69% of the placentas, and of these 55(58% were scored HCA Grade 1, and 11(12% HCA Grade 2. Infants exposed to HCA Grade 1 and Grade 2, when compared to those not exposed, presented significantly lower gestational ages, higher prevalence of RDS, clinical early-onset sepsis, and the use of supplemental oxygen more than 28 days. Infants exposed to HCA also had significantly lower maximal flows. There was a significant negative trend for z-scores of lung function in relation to levels of HCA; infants had lower maximal expiratory flows with increasing level of HCA. (p = 0.012 for FEF50, p = 0.014 for FEF25-75 and p = 0.32 for FEV0.5. Two-way ANOVA adjusted for length and gestational age indicated a significant interaction between sex and HCA in determining expiratory flows (p<0.01 for FEF50, FEF25-75 and p<0.05 for FEV0.5. Post-hoc comparisons revealed that female preterm infants exposed to HCA Grade 1 and Grade 2 had significant lower lung function than those not exposed, and this effect was not observed among males. CONCLUSIONS: Our findings show a sex-specific negative effect of prenatal inflammation on lung function of female preterm infants. This study confirms and expands knowledge upon the known association between chorioamnionitis and early life chronic lung disease.

    Full Text Available Objective: to study the nanostructure of red blood cell membranes and erythrocyte index in preterm neonatal infants.Subjects and methods. The trial enrolled 47 neonatal infants, including 33 preterm infants who were included in a study group and 14 fullterm infants who formed a comparative group. The gestational age of the preterm infants was 33.3±1.9 weeks and the birth weight was 2065.4±304.8 g. Red blood cell counts, hemoglobin, and erythrocyte indices were estimat ed and the red blood cells were examined using an atomicforce microscope.Results. At birth, the preterm infants showed macrocytosis, intrauterine poikylocytosis, and the impaired nanostructure of red blood cell membranes. Intrauterine hypoxia affects the red blood cell membrane nanostructures: a phospholipid bilayer and a spectrin matrix, without damaging the membrane protein component. The detected changes are reversible and directed to maintaining the functional ability of red blood cells in a critical situation. At birth, gestational age, a baby's weight, hemoglobin, and blood cholesterol and standard bicarbonate levels influence the parameters of a red blood cell component. The early neonatal period was characterized by an active process on the red blood cell membranes and a change of morphological forms, suggesting the continuing postnatal rearrangement of erythropoiesis and a preterm infant's adaptation to new environmental conditions.

    Full Text Available Objective: The aim of the present study was to determine the prevalence of psychological distress, depression, anxiety, and stress among postpartum Arab mothers of preterm or low birth weight (LBW infants and to identify maternal characteristics that can predict psychological distress among mothers of preterm infants. Methods: A hospital-based study was conducted. A representative sample of 2,091 postpartum mothers was surveyed and 1,659 women (79.3% gave their consent to participate in the study. The study was based on a face-to-face interview with a designed questionnaire covering sociodemographic characteristics, anthropometric measures, medical history, and maternal characteristics. Depression, anxiety, and stress were measured using the Depression Anxiety Stress Scale (DASS-21. Results: In the study sample, 10.2% of the postpartum mothers had preterm/LBW infants. Depression (29.4 vs. 17.3% and anxiety (26.5 vs. 11.6% were significantly more common among mothers of preterm births compared to mothers of full term infants (p < 0.001. The risk of depression in mothers of preterm/LBW infants was two times the risk in mothers of full term infants, while the risk of anxiety was 2.7 times in mothers of preterm/LBW infants than in mothers of full term infants. Young mothers and those who had less than secondary education (42.0 vs. 21.7%; p = 0.007 and lower monthly household income (72.0 vs. 53.3%; p = 0.024 were more depressed and anxious after the preterm birth when compared with mothers of full term infants. Psychological distress was higher in mothers with history of preterm birth (30.0 vs. 21.7% and delivery complications (52.0 vs. 33.3%. Conclusions: We found a greater risk of depression and anxiety in mothers of preterm births than in mothers of full term infants. Our analysis revealed that depressed and anxious women of preterm infants were younger, less educated, had a lower body weight and low household income than non-depressed and non

    We investigated whether spontaneous antigravity limbs movements in very low birth weight preterm infants were insufficient compared to those in term infants. The relationship between the quality of general movements (GMs) and antigravity limbs movements was also examined. Preterm infants with very low birth weight without central nervous system disorders nor severe respiration disorders, and healthy term infants were recruited. The infants were set in a supine position. The distance between both hands and between both feet, and the height of both hands and feet from the floor were recorded at 1-3 corrected months for preterm infants, and at 1-3 months for term infants by a 3D motion capture system. The measurements were adjusted for body proportions. GMs in preterm and term infants were assessed similarly. Thirteen preterm and 15 term infants completed the study. In preterm infants, the distance between both hands and between both feet were longer, and the height of both hands and feet were lower than those in term infants in all measurements. In term infants, the height of both hands and feet increased as they developed, but no change was observed in preterm infants. In preterm infants with abnormal GMs, the distance between both hands was longer, and the height of both hands and feet was lower than that in those with normal GMs. There were no such differences between preterm infants with normal GMs and term infants with normal GMs. Antigravity limbs movements in preterm infants within the first 3 month of corrected age were insufficient compared with those in term infants. Furthermore, no improvement with development was observed in preterm infants. In addition, preterm infants with abnormal GMs showed worse antigravity limbs movements than preterm and term infants with normal GMs. The preterm infants with normal GMs could behave similar to the full term infants.

    Preterm infants are usually nursed in incubators, but cot-nursing may provide an alternative. While there may be benefits of nursing preterm infants in open cots, there may be potential risks such as nosocomial infection caused by more handling due to easier access. To assess effects of cot-nursing versus incubator care on temperature control and weight gain in preterm infants. The standard search strategy of the Cochrane Neonatal Review Group was used. This included searches of electronic databases including the Cochrane Central Register of Controlled Trials (The Cochrane Library), Oxford Database of Perinatal Trials, MEDLINE, CINAHL, and EMBASE, as well as previous reviews including cross references through November 2009. All trials using random or quasi-random patient allocation in which infants receiving care in standard newborn cots were compared to infants managed in a conventional air heated incubator. The authors independently assessed trial quality and extracted data for the primary outcomes of temperature control and weight gain. Meta-analysis was conducted using a fixed-effect model. Eleven potential studies were identified of which five, involving 247 infants, were included in this review. When compared to incubator care, cot-nursing resulted in no significant difference in mean body temperature (MD 0.02 degrees C; 95% CI -0.02 to 0.07, four trials), though the one trial that reported on episodes of hyperthermia found this to be statistically more common in the cot-nursing group (RR 1.48; 95% CI 1.04 to 2.09). There were no statistically significant differences in weight gain. In the cot-nursing group, fewer infants were breast fed on discharge (typical RR 0.74; 95% CI 0.48 to 1.14, three trials, 150 infants) and fewer infants died prior to hospital discharge (typical RR 0.59, 95% CI 0.28 to 1.25, four trials, 235 infants) but these results failed to reach statistical significance.

    2011-10-01

    There is concern about possible consequences of gastroesophageal reflux (GER) in preterm infants. GER is perceived to be a frequent condition in these infants, often causing an exhaustive investigation and expensive therapy. We review current evidence for and against an association between GER and apnea, failure to thrive, wheezing and respiratory diseases. Although there are some limitations to the methodologies currently used for detecting GER, there is clearly a lack of unequivocal evidence supporting a causal relationship between GER and its assumed consequences, particularly in preterm infants. Despite physiologic data that stimulation of laryngeal efferents by GER may induce apnea, there is little evidence for a causal relationship between GER and apnea. Studies on preterm infants with failure to thrive have also not demonstrated an association between the latter and GER in most cases, and there is equally little evidence for a casual relationship with respiratory problems. Therefore, we believe that GER in preterm infants is only rarely associated with serious consequences and existing evidence does not support the widespread use of anti-reflux medications for treatment of these signs in this age group. An improvement of methods to identify the few preterm infants at risk for developing serious consequences of GER is urgently needed. Copyright © 2011. Published by Elsevier Ltd.

    To describe and understand how mothers utilize the opportunity to actively participate in their preterm infants' pain care using facilitated tucking by parents (FTP). Descriptive and exploratory study with postintervention interview. Finnish level III Neonatal Intensive Care Unit (NICU). Twenty-three mothers who had preterm infants born at gestational ages of 32 to 34 weeks. The parents (N=45) of 29 preterm infants were taught to use FTP. In addition, all nurses in the NICU (N=76) received the same education to support the parents' use of FTP. After 2 to 4 weeks of FTP use, the mothers (n=23) were interviewed using the Clinical Interview for Parents of High-Risk Infants with additional questions related to the infants' pain care. The interviews were analyzed inductively with cross-case analysis and deductively with a previously developed coding scheme. Facilitated tucking by parents was perceived positively and was used by all participating mothers. Three different styles of involvement in preterm infants' pain care with FTP were identified. They formed a continuum from external to random and finally to internalized involvement. In external involvement, the pain care with FTP was triggered by outside factors such as nurses, whereas in random and internalized involvement the motivation emerged from a parent. Mothers with external involvement thought that any person could apply the FTP. In random involvement, mothers were mainly absent during painful procedures, although they saw themselves as the best caregivers. In internalized involvement, the responsibility for infant pain care was shared within the family. Mothers' NICU-related stress and maternal attachment were associated with this variation. This study showed that mothers' are willing to actively participate in their preterm infants' pain care. However, the participation is unique according to mother and her experiences before and during NICU admission. Nurses need to consider these differences in mothers

    Full Text Available Introduction. Infants born between the 34[sup]th[/sup] – 36[sup]th[/sup] week of pregnancy account for 75% of all preterm infants. Their seemingly slight immaturity is related to serious health problems. Objective. The aim of the study was to analyse perinatal factors that influence the occurrence in infants of such problems as respiratory failure, metabolic problems and early onset sepsis (EOS. Materials and method. The material for the study included all mothers and their late preterm infants: 34+0 – 36+6 born in our hospital (a tertiary referral academic centre in 2010 and 2011. The course of pregnancy and delivery, the type of delivery, applied preventive measures and treatment, as well as demographic data and the clinical state of infants were all analysed. Data from individual documentation of each mother and infant were collected by 5 designated people and data reliability was independently monitored by a random control of the documentation conducted by the supervising person. Results. A statistically significant relationship between the occurrence of respiratory distress syndrome and infant immaturity, bad state after birth and sepsis in infants were confirmed. Sepsis was more common in the case of vaginal delivery, and coexisted with respiratory distress syndrome. The mother’s diseases during pregnancy, a perinatal preventive antibiotic therapy, and possible delivery complications did not influence the infection. Perinatal asphyxia in an infant positively correlated with a Caesarean section and respiratory distress syndrome after birth. Conclusions. It is necessary to thoroughly establish the type of delivery of a late preterm infant in order to prevent an infection in the newborn child. The improvement of diagnosis of intrauterine hypoxia may reduce the number of Caesarean sections. The decision about late preterm delivery should be based on indices of the mother’s state of health. Premature delivery is related to the

    Full Text Available Background Few studies have investigated the gut microbiome of infants, fewer still preterm infants. In this study we sought to quantify and interrogate the resistome within a cohort of premature infants using shotgun metagenomic sequencing. We describe the gut microbiomes from preterm but healthy infants, characterising the taxonomic diversity identified and frequency of antibiotic resistance genes detected. Results Dominant clinically important species identified within the microbiomes included C. perfringens, K. pneumoniae and members of the Staphylococci and Enterobacter genera. Screening at the gene level we identified an average of 13 antimicrobial resistance genes per preterm infant, ranging across eight different antibiotic classes, including aminoglycosides and fluoroquinolones. Some antibiotic resistance genes were associated with clinically relevant bacteria, including the identification of mecA and high levels of Staphylococci within some infants. We were able to demonstrate that in a third of the infants the S. aureus identified was unrelated using MLST or metagenome assembly, but low abundance prevented such analysis within the remaining samples. Conclusions We found that the healthy preterm infant gut microbiomes in this study harboured a significant diversity of antibiotic resistance genes. This broad picture of resistances and the wider taxonomic diversity identified raises further caution to the use of antibiotics without consideration of the resident microbial communities.

    Non-invasive ventilation (NIV) is increasingly being used in preterm infants with the purpose of reducing the risk of adverse pulmonary outcome associated with invasive mechanical ventilation. This review analyzes the evidence from physiologic and clinical studies on the use of NIV in the preterm infant. Physiologic data indicate advantages of NIV with regard to ventilation, gas exchange, breathing effort and thoraco-abdominal distortion. Data from clinical trials have consistently shown facilitation of weaning from mechanical ventilation and potential benefits in infants with RDS and apnoea. Long term improvements in respiratory outcome have also been reported but need to be confirmed in larger trials.

    Sudden infant death syndrome (SIDS) remains an important cause of infant death, particularly among infants born preterm. Prone sleeping is the major risk factor for SIDS and this has recently been shown to alter cerebrovascular control in term infants. As preterm infants are at greater risk for SIDS than those born at term, we hypothesized that their cerebrovascular control in the prone position would be reduced compared to term infants. There were 35 preterm (mean gestation 31.2 ± 0.4 w) and 17 term (mean gestation 40.1 ± 0.3 w) infants. Infants underwent daytime polysomnography at 2-4 w, 2-3 mo, and 5-6 mo postterm age. Infants slept both prone and supine and were presented with cardiovascular challenges in the form of 15° head-up tilts (HUT). Cerebral tissue oxygenation index (TOI) was recorded using near-infrared spectroscopy (NIRO-200 spectrophotometer, Hamamatsu Photonics KK, Japan) and mean arterial pressure (MAP) was recorded using a Finometer cuff (Finapres Medical Systems, Amsterdam, The Netherlands). In the prone position TOI increased following the HUT (P position. The overall pattern of response was similar in both groups, but more variable in preterm than term infants (P positions in preterm infants. Although overall the responses to head-up tilts were similar between term and preterm infants, greater variability of responses in preterm infants suggests persisting immaturity of their cerebrovascular control in the first year of life, which may contribute to their increased risk of sudden infant death syndrome. © 2015 Associated Professional Sleep Societies, LLC.

    Background Feeding intolerance occurs commonly in the NICU. Breast milk contains a large pool of transforming growth factor-beta (TGF-beta). Few studies describe TGF-beta levels in preterm milk, and the relationship to feeding intolerance (FI) remains unexplored. We measured TGF-beta levels in preterm breast milk to investigate a correlation with FI in preterm infants. Methods Prospective observational trial of 100 mother-infant pairs, enrolling infants born below 32 weeks gestation and less than 1500 grams, and mothers who planned to provide breast milk. TGF-beta levels were measured using ELISA. Infant charts were reviewed for outcomes. Results TGF-beta declined postnatally, most elevated in colostrum (p<0.01). TGF-beta 2 levels were higher than TGF-beta 1 at all time points (p<0.01). Colostrum TGF-beta levels correlated inversely with birth weight (p<0.01) and gestational age (p<0.05). One week TGF-beta 2 levels were reduced in growth-restricted infants with FI (p<0.01). Of infants with NEC, TGF-beta 2 levels appeared low, but small sample size precluded meaningful statistical comparisons. Conclusions TGF-beta levels decline temporally in preterm milk. TGF-beta 1 colostrum levels correlate inversely with birth weight and gestational age. TGF-beta 2 may play a role in FI in growth-restricted infants. The relationship of TGF-beta 2 and NEC merits future investigation. PMID:24995914

    Preterm birth is associated with worse neurodevelopmental outcome, but brain maturation in preterm infants is poorly characterized with standard methods. We evaluated white matter (WM) of infant brains at term-equivalent age, as a function of gestational age at birth, using multimodal magnetic resonance imaging (MRI). Infants born very preterm (preterm (33-36 weeks gestation) were scanned at 3 T at term-equivalent age using diffusion tensor imaging (DTI) and T2 relaxometry. MRI data were analyzed using tract-based spatial statistics, and anisotropy of T2 relaxation was also determined. Principal component analysis and linear discriminant analysis were applied to seek the variables best distinguishing very preterm and late preterm groups. Across widespread regions of WM, T2 is longer in very preterm infants than in late preterm ones. These effects are more prevalent in regions of WM that myelinate earlier and faster. Similar effects are obtained from DTI, showing that fractional anisotropy (FA) is lower and radial diffusivity higher in the very preterm group, with a bias toward earlier myelinating regions. Discriminant analysis shows high sensitivity and specificity of combined T2 relaxometry and DTI for the detection of a distinct WM development pathway in very preterm infants. T2 relaxation is anisotropic, depending on the angle between WM fiber and magnetic field, and this effect is modulated by FA. Combined T2 relaxometry and DTI characterizes specific patterns of retarded WM maturation, at term equivalent age, in infants born very preterm relative to late preterm.

    Full Text Available Background: Assessment of motor function is a vital characteristic of infant development. Alberta Infant Motor scale (AIMS is considered to be one of the tool available for screening the developmental delays, but this scale was formulated by using western samples. Every country has its own ethnic and cultural background and various differences are observed in the culture and ethnicity. Therefore, there is a need to obtain reliability for the use of AIMS in south Indian population. Purpose: To find the intra-rater and inter-rater reliability of Alberta Infant Motor Scale (AIMS on pre-term infants using the recorded video observations in Indian population. Method: 30 preterm infants in three age groups, 0-3 months (10 infants, 4-7 months (10 infants, 8-18 months (10 infants were recruited for this reliability study. The AIMS was administered to the preterm infants and the performance was videotaped. The performance was then rescored by the same therapist, immediately from the video and on another two consecutive months to estimate intra-rater reliability using ICC (3,1, two-way mixed effects model. For reporting inter-rater reliability, AIMS was scored by three different raters, using ICC (2,k two-way random effects model and by two other therapists to examine the inter and intra-rater reliability. Results: The two-way mixed effects model for intra-rater reliability of AIMS, ICC (3,1 = 0.99 and for reporting inter-rater reliability of AIMS by two-way random effects model, ICC (2,k = 0.96. Conclusion: AIMS has excellent intra and inter-rater reliability using recorded video observations among the preterm infants in India

Although the association between intraventricular hemorrhage and diabetes insipidus has been described in preterm infants, the association between diabetes insipidus and hydrocephalus, and the fact that such central diabetes insipidus could be reversible with the reduction of ventricular size, either because of spontaneous resolution or the placement of ventriculo-peritoneal shunt is first described here in neonates.

    Anemia is commonly seen in preterm infants. It may reduce the capacity of hemoglobin to transport oxygen throughout the body and may result in tissue and organ dysfunction. This study aimed to investigate the effect of anemia on the development of bronchopulmonary dysplasia (BPD) in preterm infants. 243 infants who were admitted to BaYi Children's Hospital Affiliated to Clinical Medical College in Beijing Military General Hospital with gestational age (GA) less than 32 weeks from February, 2014 to February, 2015 were included in the study. Maternal and infant data were recorded. Multivarariate logistic regression analysis was performed to determine the association between anemia and BPD. Of 243 preterm infants, the incidence of anemia was higher in BPD patients than non-BPD patients (p anemia was associated with an increased risk of BPD. Number of transfusions is also a significant risk factor for BPD (p = 0.001). Therefore, prevention and treatment of early anemia is necessary and reducing number of transfusions may reduce the incidence of BPD in preterm infants.

To reduce the extra-uterine growth delay in very low birth weight infants (VLBW the best strategy of nutrition (parenteral or enteral should be established rapidly, since the first day of life. In preterm infants, nutrition can be administered parenterally and enterally. Prematurity is the most frequent indication for parenteral nutritional support due to intestinal functional immune deficiency, deficiency of digestive enzymatic systems and reduced nutritional reserve of these infants. In terms of enteral nutrition, breast milk is the first choice. In case of preterm and VLBW infants, fortifiers are used to overcome breast milk’s protein and mineral deficiencies. When breast milk is not available, specific infant formula is the alternative.

    Cerebral MRI performed on preterm infants at term-equivalent 30 weeks' gestational age (GA) is increasingly performed as part of standard clinical care. We evaluated safety of these early MRI procedures. We retrospectively collected data on patient safety of preterm infants who underwent early MRI scans. Data were collected at fixed times before and after the MRI scan. MRI procedures were carried out according to a comprehensive guideline. A total of 52 infants underwent an MRI scan at 30 weeks' GA. Although no serious adverse events occurred and vital parameters remained stable during the procedure, minor adverse events were encountered in 26 infants (50%). The MRI was terminated in three infants (5.8%) because of respiratory instability. Increased respiratory support within 24 h after the MRI was necessary for 12 infants (23.1%) and was significantly associated with GA, birth weight and the mode of respiratory support. Hypothermia (core temperature < 36 C) occurred in nine infants (17.3%). Temperature dropped significantly after the MRI scan. Minor adverse events after MRI procedures at 30 weeks GA were common and should not be underestimated. A dedicated and comprehensive guideline for MRI procedures in preterm infants is essential.

  17. Neurologic Outcomes in Very Preterm Infants Undergoing Surgery.

    LENUS (Irish Health Repository)

    2012-01-31

    OBJECTIVE: To investigate the relationship between surgery in very preterm infants and brain structure at term equivalent and 2-year neurodevelopmental outcome. STUDY DESIGN: A total of 227 infants born at <30 weeks gestation or at a birth weight of <1250 g were prospectively enrolled into a longitudinal observational cohort for magnetic resonance imaging and developmental follow-up. The infants were categorized retrospectively into either a nonsurgical group (n=178) or a surgical group (n=30). Nineteen infants were excluded because of incomplete or unsuitable data. The surgical and nonsurgical groups were compared in terms of clinical demographic data, white matter injury, and brain volume at term. Neurodevelopmental outcome was assessed at age 2 years. RESULTS: Compared with the nonsurgical group, the infants in the surgical group were smaller and more growth-restricted at birth, received more respiratory support and oxygen therapy, and had longer hospital stays. They also had smaller brain volumes, particularly smaller deep nuclear gray matter volumes. Infants who underwent bowel surgery had greater white matter injury. Mental Developmental Index scores were lower in the surgical group, whereas Psychomotor Developmental Index scores did not differ between the groups. The Mental Developmental Index difference became nonsignificant after adjustment for confounding variables. CONCLUSION: Preterm infants exposed to surgery and anesthesia had greater white matter injury and smaller total brain volumes, particularly smaller deep nuclear gray matter volumes. Surgical exposure in the preterm infant should alert the clinician to an increased risk for adverse cognitive outcome.

    Since most of in utero bone mass accretion occurs during the third trimester and postnatal need for bone nutrients is increased, preterm infants have an increased risk of low bone mass. Early identification of the risk is of crucial importance. Quantitative ultrasound, which is a relatively inexpensive, portable, noninvasive, and radiation-free method, gives information about bone density, cortical thickness, elasticity and microarchitecture. The aim of this study was to obtain quantitative ultrasound measurements of tibial speed of sound of preterm and term infants and to assess clinical factors associated with these measurements during the first year of life. Seventy-eight preterm and 48 term infants were enrolled in this study. Measurements were made on the 10th day of life in both groups, and were repeated on the 2nd, 6th and 12th months for preterm infants and on the12th month for the term infants. Speed of sound on preterm infants was significantly decreased on the 2nd month but significantly increased on the 12th month (P = 0.00). Comparing speed of sound of term and preterm infants, 10th day measurements were significantly different (P = 0.00), but there was not any significant difference between the 12th month values (P = 0.26). There was not any relation between biochemical parameters and speed of sound. The technique has potential clinical value for assessment of bone status. Further studies with long term follow up are needed to evaluate the value of quantitative ultrasound with other bone markers to predict the risk of fracture.

  20. Maternal lactation for preterm newborn infants.

    In recent decades, neonatologists have made considerable progress in life support techniques, especially in the treatment and prevention of respiratory disorders, which has led to a higher neonatal survival rate. Research into neonatal nutrition has also produced great benefits. It has been found that one of the key points regarding the improved survival rate of infants is the necessity for nutrition that is both adequate and as natural as possible. In this respect, it is necessary to achieve a better understanding of the process, protection, support and maintenance of maternal lactation in neonatal units. Humanization of perinatal attention during delivery, respect for the rights of parents and their children, protection of the mother and child bonding process, early skin contact with the mother and greater attention to individualized care are all key factors in the reinforcement of maternal lactation and are issues that must be addressed within the field of neonatology. Research activities need to concern themselves with: (1) acquiring greater knowledge concerning the common problems and difficulties that arise with mothers and their preterm babies; (2) training healthcare professionals in these aspects, for example in the extraction and storage of milk and in improving techniques of emotional and communicational skills; (3) by means of specific programmes such as the setting up of support groups, so that the effort made to encourage the initiation of breastfeeding is justified by its continuation for as long as possible. Thus, we hope to establish standards of care based on starting, encouraging and prolonging maternal lactation, in sufficient quantity and quality, always remembering that the fundamental goal of our research is the well-being of the child and its family.

    Purpose The aim of this study was to determine if massage therapy can be used as an adjunct intervention to induce sleep in infants born preterm. Methods Thirty infants born at a minimum of 28 weeks gestational age (GA), who were at the time of the study between 32-48 weeks adjusted GA, were randomly assigned to receive massage therapy on 1 day and not receive massage on an alternate day. The Motionlogger® Micro Sleep Watch® Actigraph recorded lower extremity activity on the morning of each day. Results No significant difference was found between groups for sleep efficiency (P=.13) for the time period evaluated. Groups differed significantly during the time period after the massage ended with more infants sleeping on the non-massage day (Χ2= 4.9802, P=.026). Conclusions Massage is well tolerated in infants born preterm and infants do not fall asleep faster after massage than without massage. PMID:25251794

    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.

    Iodine is critical for normal thyroid hormone synthesis and brain development during infancy, and preterm infants are particularly vulnerable to the effects of both iodine deficiency and excess. Use of iodine-containing skin antiseptics in intensive care nurseries has declined substantially in recent years, but whether the current dietary iodine intake meets the requirement for hospitalized preterm infants is unknown. The aim of the study was to measure the iodine content of enteral and parenteral nutrition products commonly used for hospitalized preterm infants and estimate the daily iodine intake for a hypothetical 1-kg infant. We used mass spectrometry to measure the iodine concentration of seven preterm infant formulas, 10 samples of pooled donor human milk, two human milk fortifiers (HMF) and other enteral supplements, and a parenteral amino acid solution and soy-based lipid emulsion. We calculated the iodine provided by typical diets based on 150 ml/kg · d of formula, donor human milk with or without HMF, and parenteral nutrition. Preterm formula provided 16.4-28.5 μg/d of iodine, whereas unfortified donor human milk provided only 5.0-17.6 μg/d. Adding two servings (six packets) of Similac HMF to human milk increased iodine intake by 11.7 μg/d, whereas adding two servings of Enfamil HMF increased iodine intake by only 0.9 μg/d. The other enteral supplements contained almost no iodine, nor did a parenteral nutrition-based diet. Typical enteral diets for hospitalized preterm infants, particularly those based on donor human milk, provide less than the recommended 30 μg/d of iodine, and parenteral nutrition provides almost no iodine. Additional iodine fortification should be considered.

    T2-relaxometry brain MR imaging enables objective measurement of brain maturation based on the water-macromolecule ratio in white matter, but the outcome correlation is not established in preterm infants. Our study aimed to predict neurodevelopment with T2-relaxation values of brain MR imaging among preterm infants. From January 1, 2012, to May 31, 2015, preterm infants who underwent both T2-relaxometry brain MR imaging and neurodevelopmental follow-up were retrospectively reviewed. T2-relaxation values were measured over the periventricular white matter, including sections through the frontal horns, midbody of the lateral ventricles, and centrum semiovale. Periventricular T2 relaxometry in relation to corrected age was analyzed with restricted cubic spline regression. Prediction of cerebral palsy was examined with the receiver operating characteristic curve. Thirty-eight preterm infants were enrolled for analysis. Twenty patients (52.6%) had neurodevelopmental abnormalities, including 8 (21%) with developmental delay without cerebral palsy and 12 (31.6%) with cerebral palsy. The periventricular T2-relaxation values in relation to age were curvilinear in preterm infants with normal development, linear in those with developmental delay without cerebral palsy, and flat in those with cerebral palsy. When MR imaging was performed at >1 month corrected age, cerebral palsy could be predicted with T2 relaxometry of the periventricular white matter on sections through the midbody of the lateral ventricles (area under the receiver operating characteristic curve = 0.738; cutoff value of >217.4 with 63.6% sensitivity and 100.0% specificity). T2-relaxometry brain MR imaging could provide prognostic prediction of neurodevelopmental outcomes in premature infants. Age-dependent and area-selective interpretation in preterm brains should be emphasized. © 2018 by American Journal of Neuroradiology.

    This work presents an analysis of the information content of new features derived from the electrocardiogram (ECG) for the characterization of apnea-bradycardia events in preterm infants. Automatic beat detection and segmentation methods have been adapted to the ECG signals from preterm infants, through the application of two evolutionary algorithms. ECG data acquired from 32 preterm infants with persistent apnea-bradycardia have been used for quantitative evaluation. The adaptation procedure led to an improved sensitivity and positive predictive value, and a reduced jitter for the detection of the R-wave, QRS onset, QRS offset, and iso-electric level. Additionally, time series representing the RR interval, R-wave amplitude and QRS duration, were automatically extracted for periods at rest, before, during and after apnea-bradycardia episodes. Significant variations (papnea-bradycardia episodes, which could be potentially useful for the early detection and characterization of these episodes.

    This case describes the complications of intensive respiratory support in a preterm infant. During two months of rigorous nasal continuous positive airway pressure (CPAP) therapy with intermittent use of CPAP-mask and -prongs, an ulcer in the nasal mucus membrane developed into septum necrosis. Preterm infants are in high risk of needing long-term respiratory support, why it is important to bear in mind that binasal CPAP-prongs have proved to be more effective than mononasal therapy, and that CPAP-prongs and -mask have different sites of injury.

    Full Text Available Background. The purpose of this study of preterm infants was to test the effect of four approaches to the time of transition from gavage to full oral feedings, time to discharge, and weight gain during the transition. Methods. A randomized experimental design was used with four intervention groups: early start (32 weeks’ postmenstrual age/slow progressing experience (gradually increasing oral feedings offered per day; early start/maximum experience (oral feedings offered at every feeding opportunity; late start (34 weeks’ postmenstrual age/slow progressing experience; and late start/maximum experience. Results. The analysis included 86 preterm infants. Once oral feedings were initiated, infants in the late start/maximum experience group achieved full oral feeding and were discharged to home significantly sooner than infants in either early start group. Although not significantly different, these infants also achieved these outcomes sooner than infants in the late start/slow progressing experience group. There were no differences in weight gain across groups. Conclusions. Results suggest starting oral feedings later in preterm infants may result in more rapid transition to full oral feedings and discharge although not at early postnatal ages. Provision of a more consistent approach to oral feeding may support infant neurodevelopment and reduce length of hospitalization.

    Preterm infants display altered body composition compared to term infants, and weight gain is a crude indicator body composition. Childhood mid-upper arm circumference (MUAC) is a measure of nutritional status. This study investigates MUAC and mid-thigh circumference (MTC) to monitor growth in preterm infants. Preterm infants (<30-week gestation) were recruited. MUAC, MTC, weight, length and head circumference (HC) were measured at recruitment and weekly intervals until discharge. Descriptive, correlation and regression analyses were used. Ninety-three infants were recruited. Median measurement duration was eight weeks (1-19). Median gestational age was 27 weeks (23-29). Analysis by curve estimation displayed a mean increase of 2.58 mm/week (left MUAC) (p ≤ 0.0001), 2.56 mm/week (right MUAC) (p ≤ 0.0001), 4.16 mm/week (left MTC) (p ≤ 0.0001), 4.20 mm/week (right MTC) (p ≤ 0.0001). Coefficients of determination (R 2 ) were calculated using a growth regression model for MUAC and MTC (0.866-0.917); measures were comparable to growth modelling of weight (0.913), length (0.945) and HC (0.928). High concordance between left and right MUAC and MTC generated a Pearson's correlation coefficient of 0.999 (MUAC) (p ≤ 0.001) and 0.994 (MTC) (p ≤ 0.001). Data demonstrate the potential utility of MUAC and MTC as additional measures of growth in preterm infants that are reproducible over time. There is potential to gain insights to improve lean-mass accretion in preterm infants. ©2017 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    Late-preterm infants born at 34 to 36 weeks' gestation have increased risks of various health problems. Health service utilization (HSU) of late-preterm infants has not been systematically summarized before. To summarize the published literature on short- and long-term HSU by late-preterm infants versus term infants from infancy to adulthood after initial discharge from the hospital. We searched Medline, Embase, the Cumulative Index to Nursing and Allied Health Literature, and PsycINFO. Cohort and case-control studies that compared HSU (admissions, emergency department visits, etc) between late-preterm infants and term infants were included. Data extracted included study design, setting, population, HSU, covariates, and effect estimates. Fifty-two articles were included (50 cohort and 2 case-control studies). Meta-analyses with random effect models that used the inverse-variance method found that late-preterm infants had higher chances of all-cause admissions than term infants during all the time periods. The magnitude of the differences decreased with age from the neonatal period through adolescence, with adjusted odds ratios from 2.34 (95% confidence intervals 1.19-4.61) to 1.09 (1.05-1.13) and adjusted incidence rate ratios from 2.62 (2.52-2.72) to 1.14 (1.11-1.18). Late-preterm infants had higher rates of various cause-specific HSU than term infants for jaundice, infection, respiratory problems, asthma, and neurologic and/or mental health problems during certain periods, including adulthood. Considerable heterogeneity existed and was partially explained by the variations in the adjustment for multiple births and gestational age ranges of the term infants. Late-preterm infants had higher risks for all-cause admissions as well as for various cause-specific HSU during the neonatal period through adolescence.

    2013-01-01

    Full Text Available Although gastroesophageal reflux (GER is a very common phenomenon among preterm infants, its therapeutic management is still an issue of debate among neonatologists. A step-wise approach should be advisable, firstly promoting nonpharmacological interventions and limiting drugs to selected infants unresponsive to the conservative measures or who are suffering from severe GER with clinical complications. Despite of this, a concerning pharmacological overtreatment has been increasingly reported. Most of the antireflux drugs, however, have not been specifically assessed in preterm infants; moreover, serious adverse effects have been noticed in association to their administration. This review mainly aims to draw the state of the art regarding the pharmacological management of GER in preterm infants, analyzing the best piecies of evidence currently available on the most prescribed anti-reflux drugs. Although further trials are required, sodium alginate-based formulations might be considered promising; however, data regarding their safety are still limited. Few piecies of evidence on the efficacy of histamine-2 receptor blockers and proton pump inhibitors in preterm infants with GER are currently available. Nevertheless, a significantly increased risk of necrotizing enterocolitis and infections has been largely reported in association with their use, thereby leading to an unfavorable risk-benefit ratio. The efficacy of metoclopramide in GER’s improvement still needs to be clarified. Other prokinetic agents, such as domperidone and erythromycin, have been reported to be ineffective, whereas cisapride has been withdrawn due to its remarkable cardiac adverse effects.

    2014-03-01

    Full Text Available Objective: This study aimed to review the literature about blood concentrations of selenium associated with gestational age, feeding, supplementation and related clinical features in preterm infants. Data sources: Systematic review in the following databases: MEDLINE, PubMed, Google academics, SciELO. org, ScienceDirect (Elsevier and CINAHL-Plus with Full Text (EBSCO. Articles published up to January 2013 with the keywords "selenium deficiency", "selenium supplementation", "neonates", "infants", "newborn" and "preterm infants" were selected. Data synthesis: The studies reported that low blood selenium levels are associated with increased risk of respiratory diseases. Preterm infants, especially with low birth weight, presented lower selenium levels. Selenium deficiency has also been associated with the use of oral infant formula, enteral and parenteral nutrition (with or without selenium addition. The optimal dose and length of selenium supplementation is not well-established, since they are based only on age group and selenium ingestion by breastfed children. Furthermore, the clinical status of the infant affected by conditions that may increase oxidative stress, and consequently, selenium requirements is not taken into account. Conclusions: Prematurity and low birth weight can contribute to low blood selenium in premature infants. Selenium supplementation seems to minimize or prevent clinical complications caused by prematurity.

    Full Text Available Abstract Objective: Premature newborns are considered at risk for motor development deficits, leading to the need for monitoring in early life. The aim of this study was to systematically review the literature about gross motor development of preterm infants, assessed by the Alberta Infant Motor Scale (AIMS to identify the main outcomes in development. Data source: Systematic review of studies published from 2006 to 2015, indexed in Pubmed, Scielo, Lilacs, and Medline databases in English and Portuguese. The search strategy included the keywords: Alberta Infant Motor Scale, prematurity, preterm, motor development, postural control, and follow-up. Data summary: A total of 101 articles were identified and 23 were selected, according to the inclusion criteria. The ages of the children assessed in the studies varied, including the first 6 months up to 15 or 18 months of corrected age. The percentage variation in motor delay was identified in the motor outcome descriptions of ten studies, ranging from 4% to 53%, depending on the age when the infant was assessed. The studies show significant differences in the motor development of preterm and full-term infants, with a description of lower gross scores in the AIMS results of preterm infants. Conclusions: It is essential that the follow-up services of at-risk infants have assessment strategies and monitoring of gross motor development of preterm infants; AIMS is an assessment tool indicated to identify atypical motor development in this population.

    The Alberta Infant Motor Scale (AIMS) is a standardized motor assessment for young infants. This study aimed to examine the reliability of the AIMS in a group of infants born at or before 29 weeks of gestation. Fifty-nine infants born preterm were recruited. Two experienced pediatric physical therapists participated in this reliability study. Infants were assessed at 4, 8, 12, and 18 months corrected age (CA). Intrarater reliability was high (intraclass correlation coefficient [ICC] > or =0.99). The ICC for interrater reliability varied from 0.85 to 0.97. The ICC was low at 4 and 18 months CA. The AIMS is reliable in evaluating motor development in infants born preterm. Clinicians should be cautious about using the AIMS in infants at very young ages and those approaching independent ambulation. Accurate placement of the window on a movement repertoire is crucial. Attention is required when using the AIMS in infants developing atypically.

    This section is under preparation and will be included in the next issue. Main question: in preterm infants with apnea, does the use of kinesthetic stimulation lead to clinically important reductions in clinical apnea and bradycardia (>50% reduction in number of episodes), use of mechanical ventilation (IPPV) or continuous positive airways pressure (CPAP), and neurodevelopmental disability, without clinically important side effects. The standard search strategy of the Neonatal Review Group was used. This included searches of the Oxford Database of Perinatal Trials, Cochrane Controlled Trials Register, MEDLINE, previous reviews including cross references, abstracts, conferences, symposia proceedings, expert informants, and journal handsearching mainly in the English language. All trials using random or quasi-random patient allocation in which kinesthetic stimulation in preterm infants was compared to placebo or no treatment for apnea of prematurity were included. Standard methods of the Cochrane Collaboration and its Neonatal Review Group were used with separate evaluation of trial quality, data extraction by both authors and synthesis of data using relative risk and weighted mean difference. As all three trials were crossover trials, the data were extracted from all exposure periods and combined where appropriate. Measures of severity of apnea as well as the response to treatment were consistent with an evaluation of 'clinical apnea', as defined by the American Academy of Pediatrics (Nelson 1978). Three crossover studies (Korner 1978, Tuck 1982 and Jirapaet 1993) were identified that compared a form of kinesthetic stimulation to control for the treatment of apnea of prematurity. Clinically significant apnea: None of the three studies showed an important reduction (>50%) in clinical apnea. Using a lower threshold (>25%), the study by Korner 1978 found less apnea and bradycardia in infants receiving kinesthetic stimulation. Tuck 1982 demonstrated reductions in the

    Respiratory distress syndrome (RDS) is the single most important cause of morbidity and mortality in preterm infants (Greenough 1998, Bancalari 1992). Intermittent positive pressure ventilation (IPPV) with surfactant is the standard treatment for the condition. The major difficulty with IPPV is that it is invasive, resulting in airway and lung injury and contributing to the development of chronic lung disease. In spontaneously breathing preterm infants with RDS, to determine if continuous distending pressure (CDP) reduces the need for IPPV and associated morbidity without adverse effects. The standard search strategy of the Neonatal Review group was used. This included searches of the Oxford Database of Perinatal Trials, Cochrane Controlled Trials Register (The Cochrane Library, Issue 1, 2002), MEDLINE (1966-January 2002), and EMBASE (1980-January 2002), previous reviews including cross references, abstracts, conference and symposia proceedings, expert informants, journal hand searching mainly in the English language. All trials using random or quasi-random allocation of preterm infants with RDS were eligible. Interventions were continuous distending pressure including continuous positive airway pressure (CPAP) by mask, nasal prong, nasopharyngeal tube, or endotracheal tube, or continuous negative pressure (CNP) via a chamber enclosing the thorax and lower body, compared with standard care. Standard methods of the Cochrane Collaboration and its Neonatal Review Group were used, including independent assessment of trial quality and extraction of data by each author. CDP is associated with a lower rate of failed treatment (death or use of assisted ventilation) [summary RR 0.70 (0.55, 0.88), RD -0.22 (-0.35, -0.09), NNT 5 (3, 11)], overall mortality [summary RR 0.52 (0.32, 0.87), RD -0.15 (-0.26, -0.04), NNT 7 (4, 25)], and mortality in infants with birthweights above 1500 g [summary RR 0.24 (0.07, 0.84), RD -0.281 (-0.483, -0.078), NNT 4 (2, 13)].

    Full Text Available BACKGROUND: Ventilator injury has been implicated in the pathogenesis of bronchopulmonary dysplasia. Avoiding invasive ventilation could reduce lung injury, and early respiratory management may affect pulmonary outcomes. OBJECTIVE: To analyze the effect of initial respiratory support on survival without bronchopulmonary dysplasia at a gestational age of 36 weeks. DESIGN/METHODS: A prospective 3-year observational study. Preterm infants of 26 weeks (sensitivity =89.5% and specificity = 67%. The need for prolonged mechanical ventilation could be an early marker for the development of bronchopulmonary dysplasia. This finding could help identify a target population with a high risk of chronic lung disease. Future research is needed to determine other strategies to prevent bronchopulmonary dysplasia in this high-risk group of patients.

    Infants born at less than  34 weeks' gestational age are at higher risk for morbidity and mortality. Data are limited on the impact of maternal obesity on the very preterm infant. This study reviewed whether maternal obesity further increases the intensive care needs of very preterm infants of less than 34 weeks' gestation. Maternal and neonatal data for live-born singleton births of 23 0/7 to 33 6/7 weeks' gestation delivering in upstate New York were reviewed. BMI categorization followed the National Institutes of Health BMI classification that subdivides obesity into three ascending BMI groups. Records were obtained on 1,224 women, of whom 31.6% were classified with obesity. Despite similar mean gestational age (31 to 31.6 weeks, P = 0.57) and birth weight (1,488 to 1,569 g, P = 0.51) of the infants in the BMI categories, delivery room (DR) resuscitation was more common for infants of women with level III obesity (63.2%, P = 0.04) with a trend toward the continued need for assisted ventilation (54.7%, P = 0.06). Preterm infants of women with level III obesity were more likely to require DR resuscitation with a trend to continued need for ventilatory support beyond 6 hours of age. This could impact utilization of DR resources at delivering hospitals. © 2017 The Obesity Society.

    Scheduled interval feeding of prescribed enteral volumes is current standard practice for preterm infants. However, feeding preterm infants in response to their hunger and satiation cues (ad libitum or demand/semi demand) rather than at scheduled intervals might help in the establishment of independent oral feeding, increase nutrient intake and growth rates, and allow earlier hospital discharge. To assess the effect of a policy of feeding preterm infants on an ad libitum or demand/semi-demand basis versus feeding prescribed volumes at scheduled intervals on growth rates and the time to hospital discharge. We used the standard search strategy of the Cochrane Neonatal Review Group. This included searches of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 4, 2009), MEDLINE (1966 to Oct 2009), EMBASE (1980 to Oct 2009), CINAHL (1982 to Oct 2009), conference proceedings, and previous reviews. Randomised or quasi-randomised controlled trials (including cluster randomised trials) that compared a policy of feeding preterm infants on an ad libitum or demand/semi-demand basis versus feeding at scheduled intervals. We used the standard methods of the Cochrane Neonatal Review Group with separate evaluation of trial quality and data extraction by two review authors. We found eight randomised controlled trials that compared ad libitum or demand/semi-demand regimens with scheduled interval regimes in preterm infants in the transition phase from intragastric tube to oral feeding. The trials were generally small and of variable methodological quality. The duration of the intervention and the duration of data collection and follow-up in most of the trials was not likely to have allowed detection of measurable effects on growth. Three trials reported that feeding preterm infants using an ad libitum or demand/semi-demand feeding regimen allowed earlier discharge from hospital (by about two to four days) but other trials did not confirm this

  7. Nutrient supplies for optimal health in preterm infants.

    2007-12-01

    The most commonly recommended standard for postnatal nutrition of very preterm infants is one that meets the unique nutritional requirements of the growing human fetus and duplicates normal in utero human fetal growth (weight and body composition) and development. Normal fetal nutrition, therefore, may be a useful guide for designing postnatal nutritional strategies in very preterm infants who need to grow and develop outside the uterus. Such information indicates that normal fetal nutrition requires certain nutrients in optimal amounts and certain growth-promoting hormones in response to nutrient supply that together support optimal fetal growth and development; these include oxygen, glucose, lipids, amino acids, and insulin. Interestingly, nutrient restriction and nutrient excess in the fetus, while leading to different phenotypes, produce a similar phenotype in later life characterized as the "metabolic syndrome," consisting of obesity, insulin resistance, diabetes, and cardiovascular disease. After birth, preterm infants--who almost universally are not fed as much as normally growing fetuses receive in nutrient supply via the placenta--also end up with a higher incidence of short stature and a predisposition to the metabolic syndrome, whereas those fed excessive amounts of energy and who develop excessive growth primarily of adipose tissue in early life (rapid, positive crossing of weight-for-length centiles) also develop a higher incidence of the metabolic syndrome. It is clear, therefore, that just the right amount of the essential nutrients is required to produce optimal outcome; this is as true for the preterm infant as it is for the fetus.

    Preterm infants often exhibit functional disorders due to the stressful environment in the neonatal intensive care unit (NICU). The sound pressure level (SPL) in the NICU is often much higher than the levels recommended by the American Academy of Pediatrics. Our study aims to describe the SPL and sound frequency levels surrounding preterm infants within closed incubators that utilize high frequency oscillation (HFO) or nasal directional positive airway pressure (nasal-DPAP) respiratory settings. This is a descriptive research study of eight preterm infants (corrected ageincubator. The actual noise levels were observed and the results were compared to the recommendations made by neonatal experts. Increased noise levels, which have reported to affect neonates' ability to self-regulate, could increase the risk of developing attention deficit disorder, and may result in tachycardia, bradycardia, increased intracranial pressure, and hypoxia. The care provider should closely assess for adverse effects of higher sound levels generated by different modes of respiratory support and take measures to ensure that preterm infants are protected from exposure to noise exceeding the optimal safe levels.

    Full Text Available Background. Obstructive sleep apnea syndrome (OSAS is a frequent disorder in children. The clinical characteristics of OSAS in very young children under 2 years of age, and more particularly, in those born prematurely, and who have respiratory complications such as bronchopulmonary dysplasia (BPD, are not well defined. We therefore retrospectively reviewed our experience in a group of preterm infants with OSAS. Methods. The records of premature infants with BPD followed in the Pediatric Pulmonary Clinic at the University of Chicago who were diagnosed with OSAS from 2004-2009 were reviewed and analyzed.Results. Twelve children, 8 males and 4 females with a mean gestational age of 27 weeks were found to have OSAS. Mean age at diagnosis was 19 months. Inability to wean nighttime oxygen, the need to resume oxygen after intercurrent respiratory illness, and snoring were the most common presenting symptoms. The apnea-hypopnea index (AHI ranged from 1 to120/hrTST (mean: 29. SpO2 nadir ranged from 50% to 91%. Despite adenotonsillectomy (T&A, all children had persistent sleep disordered breathing.Conclusions. In preterm infants, while snoring is a frequent symptom, poor weight gain and inability to wean nighttime oxygen may indicate the need for further investigation for OSAS. In the former preterm infant structural changes in the airway may play an important role along with adenotonsillar hypertrophy. A high index of suspicion is required to identify OSA in the formerly preterm infant.

    Background Late preterm birth is associated with lower rates of breastfeeding and earlier breastfeeding cessation than term birth. Purpose The objectives of this secondary analysis were to compare the incidence of exclusive breastfeeding after late preterm and term childbirth and to examine the association between infant feeding outcomes and maternal emotional well-being. Methods Participants were 105 mother-infant dyads (54 late preterm and 51 term) at a southeastern U.S. medical center. Face-to-face data collection and telephone follow up occurred during 2009-2012. Results Late preterm mothers were less likely to exclusively provide their milk than were term mothers during hospitalization. Feeding at one month did not differ between late preterm and term infants. Among late preterm mothers, (1) formula supplementation during hospitalization was associated with greater severity of anxiety compared to those exclusively providing formula and (2) exclusive provision of human milk at one month was associated with less severe depressive symptoms relative to those supplementing or exclusively formula feeding. Among term mothers, feeding outcome was not related to emotional well-being measures at either time point. Implications for Practice Mothers of late preterm infants may particularly benefit from anticipatory guidance and early mental health screening, with integrated, multidisciplinary lactation teams to support these interrelated health care needs Implications for Research Prospective research is critical to document women’s intentions for infant feeding and how experiences with childbirth and the early postpartum period impact achievement of their breastfeeding plans.

    2016-01-01

    Background: Studies have explored the risk for and impact of respiratory syncytial virus (RSV) infection requiring hospitalization among healthy preterm infants born at 29–35 weeks of gestational age not given RSV immunoprophylaxis. We performed a systematic review and qualitative synthesis of these studies. Methods: Two experienced reviewers used prespecified inclusion/exclusion criteria to screen titles/abstracts and full-text studies using MEDLINE, Embase, BIOSIS and Cochrane Library (January 1, 1985, to November 6, 2014). We abstracted data on risk factors for RSV hospitalization, incidence and short- and long-term outcomes of RSV hospitalization. Using standard procedures, we assessed study risk of bias and graded strength of evidence (SOE). Results: We identified 4754 records and reviewed 27. Important risk factors for RSV hospitalization included young age during the RSV season, having school-age siblings and day-care attendance, with odds ratios >2.5 in at least one study (high SOE). Incidence rates for RSV hospitalizations ranged from 2.3% to 10% (low SOE). Length of hospital stays ranged from 3.8 to 6.1 days (low SOE). Recurrent wheezing rates ranged from 20.7% to 42.8% 1 to 2 years after RSV hospitalization (low SOE). Conclusions: Young chronological age and some environmental risk factors are important clinical indicators of an increased risk of RSV hospitalization in healthy preterm infants 32 to 35 weeks of gestational age. SOE was low for estimates of incidence of RSV hospitalizations, in-hospital resource use and recurrent wheezing in this population. Studies were inconsistent in study characteristics, including weeks of gestational age, age during RSV season and control for confounding factors. PMID:27093166

However, the SGA preterm infants remained lighter, shorter and with smaller head circumferences than the AGA preterm infants until 3 months of corrected age. The greater lean tissue deficits and an earlier "catch-up" in fat in the SGA group can reflect growth patterns variability since the early life.

    There has been an increasing interest in the application of non-invasive respiratory support in preterm infants, and different types of nasal continuous positive airway pressure (N-CPAP) devices are being used in Neonatal Intensive Care Units (NICUs). The objective of the present study was to compare the duration of CPAP need and possible complications of two methods of (N-CPAP) delivery: Bubble CPAP (B-CPAP) and Medijet (MJ) system device in preterm infants with respiratory distress syndrome (RDS). This prospective randomized clinical trial was performed on 161 preterm infants (28-37 weeks of gestational age) with RDS and eligible for CPAP therapy. The infants were inborn and admitted in a level III NICU of Al-Zahra Teaching Hospital (Tabriz, Iran) from April 2010 to September 2011. All infants were randomized in the first hour of life to B-CPAP or MJ system. Short binasal prongs were used in both groups and CPAP was set at the level of 5-6 cm H2O. The primary outcome of this study was duration of CPAP need (hour). Other outcomes, such as complications of the two methods of N-CPAP, were evaluated using a checklist. Ninety infants were randomized to the MJ system, and 71 were randomized to B-CPAP. The mean gestational age and birth weight were similar in the two groups, as was the duration of CPAP need (44.3 ± 20.64 vs. 49.2 ± 21.2 hours, respectively; p=0.66). Moreover, the probability of complications, such as CPAP failure rate, pulmonary hemorrhage, pneumothorax, intraventricular hemorrhage, abdominal distention, necrotizing enterocolitis, and bronchopulmonary dysplasia, was the same between the two study groups (p>0.05). There was a trend of more hyperemia of the nose in the B-CPAP group in comparison to the MJ system group (10% versus 3.3%, respectively), but the difference was not significant (p=0.08). In conclusion, the MJ system is as effective as B-CPAP in the management of infants with RDS.

    Background Prematurity can disrupt the development of a specialized neural circuit known as suck central pattern generator (sCPG), which often leads to poor feeding skills. The extent to which suck can be entrained using a synthetically patterned orocutaneous input to promote its development in preterm infants who lack a functional suck is unknown. Objective To evaluate the effects of a new motorized ‘pulsating’ pacifier capable of entraining the sCPG in tube-fed premature infants who lack a functional suck and exhibit feeding disorders. Methods Prospective cohort study of 31 preterm infants assigned to either the oral patterned entrainment intervention (study) or non-treated (controls) group, matched by gestational age, birth weight, oxygen supplementation history, and oral feed status. Study infants received a daily regimen of orocutaneous pulse trains through a pneumatically-controlled silicone pacifier concurrent with gavage feeds. Results The patterned orocutaneous stimulus was highly effective in accelerating the development of NNS in preterm infants. A repeated-measure multivariate analysis of covariance revealed significant increases in minute-rates for total oral compressions, NNS bursts, and NNS cycles, suck cycles per burst, and the ratiometric measure of NNS cycles as a percentage of total ororhythmic output. Moreover, study infants also manifest significantly greater success at achieving oral feeds, surpassing their control counterparts by a factor of 3.1× (72.8% daily oral feed versus 23.3% daily oral feed, respectively). Conclusion Functional expression of the sCPG among preterm infants who lack an organized suck can be induced through the delivery of synthetically patterned orocutaneous pulse trains. The rapid emergence of NNS in treated infants is accompanied by a significant increase in the proportion of nutrient taken orally. PMID:18548084

    Stress systems may be altered in the long term in preterm infants for multiple reasons, including early exposure to procedural pain in neonatal intensive care. This question has received little attention beyond hospital discharge. Stress responses (cortisol) to visual novelty in preterm infants who were born at extremely low gestational age (ELGA; neonatal exposure to procedural pain and morphine in the neonatal intensive care unit. Seventy-six infants, 54 preterm (neonatal skin-breaking procedures. In contrast, cortisol responses to novelty were predicted equally well by neonatal pain or GA at birth. No relationship between morphine dosing and cortisol response was demonstrated in these infants. ELGA preterm infants show a different pattern of cortisol levels before and after positive stimulation of visual novelty than more maturely born, VLGA preterm and term-born infants. Exposure to high numbers of skin-breaking procedures may contribute to "resetting" basal arousal systems in preterm infants.

    Stabilization of respiration and oxygenation continues to be one of the main challenges in clinical care of the neonate. Despite aggressive respiratory support including mechanical ventilation, continuous positive airway pressure, oxygen and caffeine therapy to reduce apnea and accompanying intermittent hypoxemia, the incidence of intermittent hypoxemia events continues to increase during the first few months of life. Even with improvements in clinical care, standards for oxygen saturation targeting and modes of respiratory support have yet to be identified in this vulnerable infant cohort. In addition, we are only beginning to explore the association between the incidence and pattern of cardiorespiratory events during early postnatal life and both short- and long-term morbidity including retinopathy of prematurity, growth, sleep-disordered breathing and neurodevelopmental impairment. Part 1 of this review included a summary of lung development and diagnostic methods of cardiorespiratory monitoring. In Part 2 we focus on clinical interventions and the short- and long-term consequences of cardiorespiratory events in preterm infants.

    Recently, more and more researchers have been using salivary cortisol reactivity to evaluate stress in preterm infants in the neonatal intensive care unit (NICU). The aim of this integrative literature review was to summarize the evidence of interventions leading to a change in salivary cortisol from the baseline in preterm infants in the NICU. The electronic databases of PubMed, CINAHL, Web of Science, and Scopus were searched for relevant studies. The inclusion criteria were studies with preterm infants exposed to an intervention evaluated by salivary cortisol reactivity before discharge from the NICU, which were published in English. In total, 16 studies were included. Eye-screening examination and heel lance provoked an increase in the salivary cortisol level. Music, prone position, and co-bedding among twins decreased the salivary cortisol level. Several studies reported a low rate of successful saliva sampling or did not use control groups. Future studies need to focus on non-painful interventions in order to learn more about salivary cortisol regulation in preterm infants. Moreover, these studies should use study designs comprising homogenous gestational and postnatal age groups, control groups, and reliable analysis methods that are able to detect cortisol in small amounts of saliva.

    Preterm and low-birth-weight infants have an increased risk of sensorineural hearing loss. Brainstem auditory-evoked potentials (BAEP) are an effective method to detect subtle deficits in impulse conduction in the auditory pathway. Abnormalities on diffusion tensor imaging (DTI) have been shown to be associated with perinatal white-matter injury and reduced fractional anisotropy (FA) has been reported in patients with sensorineural hearing loss. To evaluate the possibility of a correlation between BAEP and DTI of the inferior colliculus in preterm infants. DTI at term age and BAEP measurements were performed on all very-low-birth-weight or very preterm study infants (n=56). FA and apparent diffusion coefficient (ADC) of the inferior colliculus were measured from the DTI. Shorter BAEP wave I, III, and V latencies and I-III and I-V intervals and higher wave V amplitude correlated with higher FA of the inferior colliculus. The association between the DTI findings of the inferior colliculus and BAEP responses suggests that DTI can be used to assess the integrity of the auditory pathway in preterm infants. (orig.)

    Insufficient leukocyte recruitment may be one reason for the high incidence of life-threatening infections in preterm infants. Since the receptor of advanced glycation end products (RAGE) is a known leukocyte adhesion molecule and highly expressed during early development, we asked whether RAGE plays a role for leukocyte recruitment in preterm and term infants. Leukocyte adhesion was analyzed in dynamic flow chamber experiments using isolated leukocytes of cord blood from extremely premature (35 weeks of gestation) and compared to the results of adults. For fluorescent microscopy leukocytes were labeled with rhodamine 6G. In the respective age groups we also measured the plasma concentration of soluble RAGE (sRAGE) by ELISA and Mac-1 and LFA-1 expression on neutrophils by flow cytometry. The adhesive functions of fetal leukocytes significantly increase with gestational age. In all age groups, leukocyte adhesion was crucially dependent on RAGE. In particular, RAGE was equally effective to mediate leukocyte adhesion when compared to ICAM-1. The plasma levels of sRAGE were high in extremely premature infants and decreased with increasing gestational age. In contrast, expression of β2-Integrins Mac-1 and LFA-1 which are known ligands for RAGE and ICAM-1 did not change during fetal development. We conclude that RAGE is a crucial leukocyte adhesion molecule in both preterm and term infants.

    Objective To test the effects of kangaroo care (KC) on breastfeeding outcomes in preterm infants compared to two control groups and to explore whether maternal-infant characteristics and the mother’s choice to use KC were related to breastfeeding measures. Design Secondary analysis of a multisite, stratified, and randomized 3-arm trial. The treatment groups used KC, auditory-tactile-visual-vestibular (ATVV) intervention, or preterm infant care information. Setting Neonatal intensive care units from 4 hospitals in the United States from 2006–2011. Participants Racially diverse mothers (N=231) and their preterm infants born weighing breastfeeding, and breastfeeding exclusivity after hospital discharge did not differ statistically among the treatment groups. Regardless of group assignment, married, older, and more educated women were more likely to feed at the breast during hospitalization. Mothers who practiced KC, regardless of randomly allocated group, were more likely to provide their milk than those who did not practice KC. Breastfeeding duration was greatest among more educated women. Conclusion As implemented in this study, assignment to KC did not appear to influence the measured breastfeeding outcomes.

    Scientific and clinical advances in perinatology and neonatology have enhanced the chances of survival of preterm and very low weight neonates. Infant cry analysis is a suitable noninvasive complementary tool to assess the neurologic state of infants particularly important in the case of preterm neonates. This article aims at exploiting differences between full-term and preterm infant cry with robust automatic acoustical analysis and data mining techniques. Twenty-two acoustical parameters are estimated in more than 3000 cry units from cry recordings of 28 full-term and 10 preterm newborns. Feature extraction is performed through the BioVoice dedicated software tool, developed at the Biomedical Engineering Lab, University of Firenze, Italy. Classification and pattern recognition is based on genetic algorithms for the selection of the best attributes. Training is performed comparing four classifiers: Logistic Curve, Multilayer Perceptron, Support Vector Machine, and Random Forest and three different testing options: full training set, 10-fold cross-validation, and 66% split. Results show that the best feature set is made up by 10 parameters capable to assess differences between preterm and full-term newborns with about 87% of accuracy. Best results are obtained with the Random Forest method (receiver operating characteristic area, 0.94). These 10 cry features might convey important additional information to assist the clinical specialist in the diagnosis and follow-up of possible delays or disorders in the neurologic development due to premature birth in this extremely vulnerable population of patients. The proposed approach is a first step toward an automatic infant cry recognition system for fast and proper identification of risk in preterm babies. Copyright © 2016 The Voice Foundation.

    The doubly labeled water method was compared with indirect calorimetry and a nutrient-balance study for simultaneous determination of rates of CO/sub 2/ production, energy expenditure, and water intake over 5 days in four preterm infants. Additionally, metabolizable energy (ME) intake estimated using the isotope procedure (as energy expenditure plus an estimate for energy deposition based on weight gain), was compared to ME intake measured in the balance study. Compared to values obtained by traditional methods, calculated CO/sub 2/ production, energy expenditure, and water intake differed by -1.4 +/- 4.8% (SD), +0.3 +/- 2.6%, and +5.7 +/- 1.4%, respectively; the difference in water intake was significant (p less than 0.05). Calculated ME intakes were 5.3 +/- 19.3% less than measured intakes, but the difference was not significant. These findings indicate that the doubly labeled water method can provide accurate information on rates of CO/sub 2/ production, energy expenditure, and water intake in preterm infants, but individual estimates of ME intake may be subject to substantial error.

    The aim of this study was to compare infants' sleep measures through an actigraph and maternal parenting stress among preterm and full-term mothers, and to explore the factors affecting maternal parenting stress in relation to infants' sleep. The subjects were 44 pairs of mothers and children. Twenty-one were in the preterm group, and 23 were in the full-term group. Inclusion criteria for preterm infants were born at less than 36 weeks and birthweight of less than 2500 g. The Parenting Stress Index (PSI) Short Form assesses maternal perception of the degree of parenting stress: the children's domain, and the parent's domain. An actigraph was applied to assess the infants' sleep measures. The PSI showed significant differences, with high scores in parenting stress in the preterm group. Also, the number of mothers who complained about their infant's sleep issues was significantly higher in the preterm group. Most of the sleep measures showed improvement by their age in both preterm and full-term infants. Multiple linear regression analysis showed that sleep efficiency, longest sleep duration at nighttime accounted for 71% of stress in the children's domain of the PSI of the preterm group. The parenting stress among mothers of preterm infants was significantly higher than that of mothers of full-term infants. The mothers of preterm infants were concerned about their infant's nocturnal sleep quality. © 2013 The Authors. Pediatrics International © 2013 Japan Pediatric Society.

    International guidelines recommend that an appropriately sized face mask for providing positive pressure ventilation should cover the mouth and nose but not the eyes and should not overlap the chin. This study aimed to measure the dimensions of preterm infants' faces and compare these with the size of the most commonly available face masks (external diameter 50 mm) and the smallest masks available (external diameters 35 and 42 mm). Infants 24-33 weeks' postmenstrual age (PMA) were photographed in a standardised manner. Images were analysed using ImageJ software (National Institute of Health, USA) to calculate the distance from the nasofrontal groove to the mental protuberance. This facial measurement corresponds to the external diameter of an optimally fitting mask. A cohort of 107 infants between 24 and 33 weeks' gestational age, including at least 10 infants per week of gestation, was photographed within 72 h after birth and weekly until 33 weeks' PMA. 347 photographs were analysed. Infants of 24, 26, 28, 30 and 32 weeks' PMA had mean (SD) facial measurements of 32 (2), 36 (3), 38 (4), 41 (2) and 43 (4) mm, respectively. There were no significant differences when examined by gender or when small for gestational age infants were excluded. The smallest size of some brands of mask is too large for many preterm infants. Masks of 35 mm diameter are suitable for infants Masks of 42 mm diameter are suitable for infants 27-33 weeks' PMA or 750-2500 g. Published by the BMJ Publishing Group Limited.

    AIM: Necrotising enterocolitis contributes considerably to the mortality of preterm infants, but most questions remain unsolved after decades of extensive research. This Danish study investigated the validity of necrotising enterocolitis diagnoses at discharge according to Bell's staging system....... METHODS: We conducted a retrospective single-centre cohort study of 714 preterm infants with a gestational age of less than 30 weeks born in 2006-2013. The infants were diagnosed with necrotising enterocolitis according to Bell's stages 2-3 at discharge and in retrospect by an expert panel, which served...... as our gold standard. RESULTS: The sensitivity of necrotising enterocolitis diagnosed at discharge was 0.72-0.75 depending on whether spontaneous intestinal perforation was included as necrotising enterocolitis or not. The positive predictive value of the diagnosis was 0.49-0.61. The incidence...

  7. Evaluation and treatment of hypotension in the preterm infant.

    LENUS (Irish Health Repository)

    Dempsey, E M

    2012-01-31

    A large proportion of very preterm infants receive treatment for hypotension. The definition of hypotension is unclear, and, currently, there is no evidence that treating it improves outcomes or, indeed, which treatment to choose among the available alternatives. Assessment of circulatory adequacy of the preterm infant requires a careful clinical assessment and may also require ancillary investigations. The most commonly used interventions, fluid boluses and dopamine, are problematic: fluid boluses are statistically associated with worse clinical outcomes and may not even increase blood pressure, whereas dopamine increases blood pressure mostly by causing vasoconstriction and may decrease perfusion. For neither intervention is there any reliable data showing clinical benefit. Prospective trials of intervention for hypotension and circulatory compromise are urgently required.

    There are significant international variations in chronic lung disease rates among very preterm infants yet there is little data on international variations in respiratory strategies. To evaluate practice variations in the respiratory management of extremely preterm infants born at < 29 weeks' gestational age (GA) among 10 neonatal networks participating in the International Network for Evaluating Outcomes (iNeo) of Neonates collaboration. A web-based survey was sent to the representatives of 390 neonatal intensive care units from Australia/New Zealand, Canada, Finland, Illinois (USA), Israel, Japan, Spain, Sweden, Switzerland, and Tuscany (Italy). Responses were based on practices in 2015. Overall, 321 of the 390 units responded (82%). The majority of units within networks (40-92%) mechanically ventilate infants born at 23-24 weeks' GA on continuous positive airway pressure (CPAP) with 30-39% oxygen in respiratory distress within 48 h after birth, but the proportion of units that offer mechanical ventilation for infants born at 25-26 weeks' GA at similar settings varied significantly (20-85% of units within networks). The most common respiratory strategy for infants born at 27-28 weeks' GA on CPAP with 30-39% oxygen with respiratory distress within 48 h after birth used by units also varied significantly among networks: mechanical ventilation (0-60%), CPAP (3-82%), intubation and surfactant administration with immediate extubation (0-75%), and less invasive surfactant administration (0-68%). There are marked variations but also similarities in respiratory management of extremely preterm infants between networks. Further collaboration and exploration is needed to better understand the association of these variations in practice with pulmonary outcomes. © 2018 S. Karger AG, Basel.

    Preterm infants begin the transition from gastric tube feeds to sucking feeds around 34 weeks' postmenstrual age. We compared physiological stability in two bottle feeding positions, cradle hold versus side lying in preterm infants. Randomised crossover trial of infants position 94 (6) % versus 95 (6) %, respectively (P = 0.55, confidence interval (CI) -1.4, 5.4). During feeds, 17/25 (68%) experienced a period of SpO₂ position compared with 14/25 (56) % in the side-lying position (P = 0.26, CI 0.68, 4.10). There were no significant differences in the mean HR or number of episodes of bradycardia HR position compared with the side-lying position, 82 (25) % versus 87 (20) % (P = 0.08, CI -0.64, 10.00). There was little difference in infants' physiological stability between the two bottle feeding positions. Both methods may be appropriate for the transition from gastric tube to sucking feeds in preterm infants. © 2013 The Authors.

    The influence of short-term aminophylline treatment on sleep behaviour was studied in six preterms infants with recurrent apnea. The incidence of apnea, respiratory pauses, and bradycardias which were closely related to the phases of active sleep, decreased during aminophylline treatment. However, the amount of active sleep remained unaffected. The mode of action of aminophylline is discussed in view of the previously proposed neurophysiological concept of apnea of prematurity.

    Full Text Available AbstractLate preterm infants (34 to 36 weeks’ gestation remain a population at risk for apnea of prematurity (AOP. As infants affected by respiratory distress syndrome (RDS have immature lungs, they might also have immature control of breathing. Our hypothesis is that an association exists between RDS and AOP in late preterm infants.ObjectiveThe primary objective of this study was to assess the association between RDS and AOP in late preterm infants. The secondary objective was to evaluate if an association exists between apparent RDS severity and AOP.MethodsThis retrospective observational study was realized in a tertiary care center between January 2009 and December 2011. Data from late preterm infants who presented an uncomplicated perinatal evolution, excepted for RDS, were reviewed. Information related to AOP and RDS were collected using the medical record. Odds ratios were calculated using a binary logistic regression adjusted for GA and sex.ResultsAmong the 982 included infants 85 (8,6% had an RDS diagnosis, 281 (28,6% had AOP diagnosis and 107 (10,9% were treated with caffeine for AOP. There was a significant association between AOP treated with caffeine and RDS for all infants (OR = 3.3, 95% CI : 2.0 – 5.7. There was no association between AOP and RDS in 34 weeks infants [AOR : 1.6 (95% CI: 0.7 – 3.8] but an association remains for 35 [AOR : 5.7 (95% CI: 2.5 – 13.4] and 36 [OR: 7.8 (95% CI: 3.2 – 19.4] weeks infants. No association was found between apparent RDS severity and AOP regarding mean oxygen administration duration or complications associated with RDS.ConclusionThe association between RDS and AOP in late preterm infants reflects that patients affected by RDS are not only presenting lung immaturity, but also respiratory control immaturity. Special consideration should be given before discontinuing monitoring after RDS resolution in those patients.

    Preterm birth (birth before 37 wk of gestation) occurs in about 8% of pregnancies in Canada and is associated with high mortality and morbidity rates that substantially affect infants, their families and the health care system. Our overall goal is to create a transdisciplinary platform, the Canadian Preterm Birth Network (CPTBN), where investigators, stakeholders and families will work together to improve childhood outcomes of preterm neonates. Our national cohort will include 24 maternal-fetal/obstetrical units, 31 neonatal intensive care units and 26 neonatal follow-up programs across Canada with planned linkages to provincial health information systems. Three broad clusters of projects will be undertaken. Cluster 1 will focus on quality-improvement efforts that use the Evidence-based Practice for Improving Quality method to evaluate information from the CPTBN database and review the current literature, then identify potentially better health care practices and implement identified strategies. Cluster 2 will assess the impact of current practices and practice changes in maternal, perinatal and neonatal care on maternal, neonatal and neurodevelopmental outcomes. Cluster 3 will evaluate the effect of preterm birth on babies, their families and the health care system by integrating CPTBN data, parent feedback, and national and provincial database information in order to identify areas where more parental support is needed, and also generate robust estimates of resource use, cost and cost-effectiveness around preterm neonatal care. These collaborative efforts will create a flexible, transdisciplinary, evaluable and informative research and quality-improvement platform that supports programs, projects and partnerships focused on improving outcomes of preterm neonates.

  14. Does gastroesophageal reflux cause apnea in preterm infants?

    2005-01-01

    Gastroesophageal reflux (GER) and apnea are both common occurrences in premature infants but their relationship is controversial. We present the evidence for and against an association between GER and apnea and discuss the merits and limitations of the various methodologies employed in characterizing such a relationship. Overall, GER and apnea do not appear temporally related in preterm infants, despite strong physiologic evidence that stimulation of laryngeal afferents elicits central apnea and laryngeal adduction. In a subpopulation of infants with neurodevelopmental compromise, there may be an increased incidence of both apnea and GER, although the direct association between GER and apnea in this population is unclear. Therefore, we believe there is no evidence to support widespread use of anti-reflux medications in the treatment of apnea in preterm infants. Further studies are needed to clarify the existence of a small subpopulation of infants who may have GER-induced apnea, to identify potential triggering mechanisms, and to document benefit from newer pharmacological approaches.

    To determine the effects of prone positioning on cardiorespiratory stability and weaning outcome of preterm infants during weaning from mechanical ventilation. From January to December 1999, a sample of 42 preterm infants, with birthweight position: supine position (n = 21) or prone position (n = 21). Heart rate, respiratory rate, transcutaneous oxygen saturation and ventilatory parameters were recorded every one hour. Length of the weaning process and complications were also assessed. In both groups the mean gestational age was 29 weeks, most of the patients presented very low birthweight and respiratory distress syndrome. The mean length of the weaning process was 2 days. There were no differences between the groups regarding respiratory rate, heart rate and transcutaneous oxygen saturation, however, oxygen desaturation episodes were more frequent in supine position (p = 0.009). Ventilatory parameters decreased faster and reintubation was less frequent in the prone group (4% versus 33%). No adverse effects of prone positioning were observed. These results suggest that prone position is a safe and beneficial procedure during weaning from mechanical ventilation and may contribute to weaning success in preterm infants.

    Apnea of prematurity affects a small proportion but large absolute number of late preterm infants, with out-patient management variably utilized despite relative clinical equipoise and potential for improved cost-effectiveness. Over a 5-y period, from 2009 to 2013, infants born at ≥34 weeks gestational age at a level IIIB academic center in Boston, Massachusetts, with discharge-delaying apnea, bradycardia, and desaturation (ABD) events were identified. In-patient costs for discharge-delaying ABD events were compared with hypothetical out-patient management. Out-patient costs took into account 4-10 d of in-patient observation for ABD events before caffeine initiation, 3-5 d of additional in-patient observation before discharge, daily caffeine until 43 weeks corrected gestational age, home pulse oximetry monitoring until 44 weeks corrected gestational age, and consideration of variable readmission rates ranging from 0 to 10%. A total of 425 late preterm and term infants were included in our analysis. Utilization of hypothetical out-patient management resulted in cost savings per eligible patient ranging from $2,422 to $62, dependent upon variable periods of in-patient observation. Sensitivity analysis demonstrated few instances of decreased relative cost-effectiveness. Out-patient management of discharge-delaying ABD events in a late preterm and term population was a cost-effective alternative to prolonged in-patient observation.

    Diffusion and fMRI has been providing insights to brain development in addition to anatomic imaging. This study aimed to evaluate the microstructure of white matter tracts underlying the default mode network in premature infants by using resting-state functional MR imaging in conjunction with diffusion tensor imaging-based tractography. A cohort of 44 preterm infants underwent structural T1-weighted imaging, resting-state fMRI, and DTI at 3T, including 21 infants with brain injuries and 23 infants with normal-appearing structural imaging as controls. Neurodevelopment was evaluated with the Bayley Scales of Infant Development at 12 months' adjusted age. Probabilistic independent component analysis was applied to resting-state fMRI data to explore resting-state networks. The localized clusters of the default mode network were used as seeding for probabilistic tractography. The DTI metrics (fractional anisotropy, mean diffusivity, axial diffusivity, and radial diffusivity) of the reconstructed primary tracts within the default mode network-cingula were measured. Results revealed decreased fractional anisotropy (0.20 ± 0.03) and elevated radial diffusivity values (1.24 ± 0.16) of the cingula in the preterm infants with brain injuries compared with controls (fractional anisotropy, 0.25 ± 0.03; P default mode network are of critical importance in the early neurocognitive development of infants. This study of combined resting-state fMRI and DTI at rest suggests that such studies may allow the investigation of key functional brain circuits in premature infants, which could function not only as diagnostic tools but also as biomarkers for long-term neurodevelopmental outcomes. © 2017 by American Journal of Neuroradiology.

    The goal of this study was to examine the reliability and validity of measurements obtained with the Alberta Infant Motor Scale (AIMS) for evaluation of preterm infants in Taiwan. Two independent groups of preterm infants were used to investigate the reliability (n=45) and validity (n=41) for the AIMS. In the reliability study, the AIMS was administered to the infants by a physical therapist, and infant performance was videotaped. The performance was then rescored by the same therapist and by 2 other therapists to examine the intrarater and interrater reliability. In the validity study, the AIMS and the Bayley Motor Scale were administered to the infants at 6 and 12 months of age to examine criterion-related validity. Intraclass correlation coefficients (ICCs) for intrarater and interrater reliability of measurements obtained with the AIMS were high (ICC=.97-.99). The AIMS scores correlated with the Bayley Motor Scale scores at 6 and 12 months (r=.78 and.90), although the AIMS scores at 6 months were only moderately predictive of the motor function at 12 months (r=.56). The results suggest that measurements obtained with the AIMS have acceptable reliability and concurrent validity but limited predictive value for evaluating preterm Taiwanese infants.

    Full Text Available Background: Infant mortality is considered as the key healthcare index in every country. The outcomes of a preterm birth are among the main and direct causes of neonate mortality. Therefore, the present research aims to investigate some maternal factors influencing the immature birth. Materials and Methods: This observational case study was conducted on 100 term babies as the control group. The questionnaires were completed through interviewed mothers or perused hospital files. Results: The results of this study showed the high chances of premature birth in women with multiple pregnancies, smoking, placenta previa, uterine problems and placental abruption compared to most of the mothers with no history of such problems. In mothers with cervical incompetence, the chances of delivering a preterm baby are 11 times as high as mothers with no such problems. Similarly, the chances are 9.33 times as high among the mothers who had a history of placenta previa. Conclusion: Identifying maternal factors influencing the preterm infant birth as well as attentive care taken during pregnancy can significantly reduce the preterm infant birth.

    Late preterm infants (LPIs) (gestation 34 weeks and 0 days to 36 weeks and 6 days) compared with full-term infants (FTIs) are at increased risk for mortality and short- and long-term morbidity. The objective of this study was to assess the neurodevelopmental outcomes in a longitudinal cohort study of LPIs from infancy to school age and determine predictive values of earlier developmental testing compared with school-age testing. We used general estimating equations to calculate the odds of school readiness in a nationally representative cohort of 4900 full-term and 950 late preterm infants. We generated positive and negative predictive values of the ability of the 24-month Mental Developmental Index (MDI) scores of the Bayley Short Form, Research Edition, to predict Total School Readiness Score (TSRS) at kindergarten age. In multivariable analysis, late preterm infants had higher odds of worse TSRSs (adjusted odds ratio 1.52 [95% confidence interval 1.06-2.18], P = .0215). The positive predictive value of a child having an MDI of kindergarten was 10.4%. The negative predictive value of having an MDI of >70 at 24 months and a TSRS >5% was 96.8%. Most infants improved score ranking over the study interval. LPIs continue to be delayed at kindergarten compared with FTIs. The predictive validity of having a TSRS in the bottom 5% given a MDI 85) at 24 months had an excellent chance of testing in the normal range at kindergarten.

    To trace a reference curve for motor development from birth up to 12 months of corrected chronological age in infants born preterm and low birth weight. This is a cross-sectional study with a sample of 308 preterm infants (53% boys) weighing Alberta Infant Motor Scale (AIMS) was used for motor development assessment. Comparing the motor performance of preterm infants with infants from a standardized sample on the AIMS, it was found that, except for the age group of the newborn, preterm infants showed lower motor development scores in comparison with the AIMS normative sample in all age groups between 1 and 12 months. The curve of motor development showed a continuous increase in the number of motor skills of preterm infants during their first 12 months of age. However, the average of motor acquisitions of preterm infants showed a nonlinear pattern with a standard indicator of stabilization between 8 and 10 months of age. Preterm infants, 1-12 months of age, showed motor development AIMS scores lower than the standards established in the normative sample. The findings may contribute as norm-reference for assessing the motor development of preterm infants in follow-up programmes in developing countries. © 2010 The Author(s)/Acta Paediatrica © 2010 Foundation Acta Paediatrica.

    The rate of evaporation from the skin (g/m2/h) was measured in 12 full-term and 16 preterm infants (gestational age 25-34 wk) both during incubator care and when nursed under a radiant heater. The method for evaporation rate measurement is noninvasive and based on determination of the water vapor pressure gradient close to the skin surface. Measurements were first made with the infant nursed in an incubator with a controlled environment with respect to humidity, temperature, and air velocity. The measurements in the term infants were performed at an ambient relative humidity (RH) of 50%, and in the preterm infants first at 50% and subsequently at 30-40%. Evaporation rate was then measured with the infant nursed under a radiant heater. In term infants, mean evaporation rate was 3.3 g/m2/h during incubator care (RH 50%) and 4.4 g/m2/h during care under the radiant heater. In preterm infants, the corresponding values were 15.5 g/m2/h in the incubator at RH 50%, 16.7 g/m2/h at RH 30-40%, and 17.9 g/m2/h under the radiant heater. It is concluded that the evaporative water loss from the skin depends on the ambient water vapor pressure, irrespective of whether the infant is nursed in an incubator or under a radiant heater. The higher rate of evaporation during care under a radiant heater is due to the lower ambient water vapor pressure and not to any direct effect of the nonionizing radiation on the skin.

    Full Text Available OBJECTIVE: To compare gross motor development of preterm infants (PT without cerebral palsy with healthy full-term (FT infants, according to Alberta Infant Motor Scale (AIMS; to compare the age of walking between PT and FT; and whether the age of walking in PT is affected by neonatal variables. METHODS: Prospective study compared monthly 101 PT and 52 FT, from the first visit, until all AIMS items had been observed. Results: Mean scores were similarity in their progression, except from the eighth to tenth months. FT infants were faster in walking attainment than PT. Birth weight and length and duration of neonatal nursery stay were related to walking delay. CONCLUSION: Gross motor development between PT and FT were similar, except from the eighth to tenth months of age. PT walked later than FT infants and predictive variables were birth weight and length, and duration of neonatal intensive unit stay.

    Apnea is nearly universal among very low birth weight (VLBW) infants, and the associated bradycardia and desaturation may have detrimental consequences. We describe here very long (>60 s) central apnea events (VLAs) with bradycardia and desaturation, discovered using a computerized detection system applied to our database of over 100 infant years of electronic signals. Eighty-six VLAs occurred in 29 out of 335 VLBW infants. Eighteen of the 29 infants had a clinical event or condition possibly related to the VLA. Most VLAs occurred while infants were on nasal continuous positive airway pressure, supplemental oxygen, and caffeine. Apnea alarms on the bedside monitor activated in 66% of events, on average 28 s after cessation of breathing. Bradycardia alarms activated late, on average 64 s after cessation of breathing. Before VLAs oxygen saturation was unusually high, and during VLAs oxygen saturation and heart rate fell unusually slowly. We give measures of the relative severity of VLAs and theoretical calculations that describe the rate of decrease of oxygen saturation. A clinical conclusion is that very long apnea (VLA) events with bradycardia and desaturation are not rare. Apnea alarms failed to activate for about one-third of VLAs. It appears that neonatal intensive care unit (NICU) personnel respond quickly to bradycardia alarms but not consistently to apnea alarms. We speculate that more reliable apnea detection systems would improve patient safety in the NICU. A physiological conclusion is that the slow decrease of oxygen saturation is consistent with a physiological model based on assumed high values of initial oxygen saturation. PMID:25549762

    ABSTRACT Objective: To conduct a systematic search for grounded and quality evidence of sensory processing in preterm infants during childhood. Data source: The search of the available literature on the theme was held in the following electronic databases: Medical Literature Analysis and Retrieval System Online (Medline)/PubMed, Latin American and Caribbean Literature in Health Sciences (Lilacs)/Virtual Library in Health (BVS), Índice Bibliográfico Español de Ciencias de la Salud (IBECS)/BVS, Scopus, and Web of Science. We included only original indexed studies with a quantitative approach, which were available in full text on digital media, published in Portuguese, English, or Spanish between 2005 and 2015, involving children aged 0-9years. Data synthesis: 581 articles were identified and eight were included. Six studies (75%) found high frequency of dysfunction in sensory processing in preterm infants. The association of sensory processing with developmental outcomes was observed in three studies (37.5%). The association of sensory processing with neonatal characteristics was observed in five studies (62.5%), and the sensory processing results are often associated with gestational age, male gender, and white matter lesions. Conclusions: The current literature suggests that preterm birth affects the sensory processing, negatively. Gestational age, male gender, and white matter lesions appear as risk factors for sensoryprocessing disorders in preterm infants. The impairment in the ability to receivesensory inputs, to integrateand to adapt to them seems to have a negative effect on motor, cognitive, and language development of these children. We highlight the feasibility of identifying sensory processing disorders early in life, favoring early clinical interventions. PMID:28977307

  7. Preterm infants have significantly longer telomeres than their term born counterparts.

    Directory of Open Access Journals (Sweden)

    Vimal Vasu

    Full Text Available There are well-established morbidities associated with preterm birth including respiratory, neurocognitive and developmental disorders. However several others have recently emerged that characterise an 'aged' phenotype in the preterm infant by term-equivalent age. These include hypertension, insulin resistance and altered body fat distribution. Evidence shows that these morbidities persist into adult life, posing a significant public health concern. In this study, we measured relative telomere length in leukocytes as an indicator of biological ageing in 25 preterm infants at term equivalent age. Comparing our measurements with those from 22 preterm infants sampled at birth and from 31 term-born infants, we tested the hypothesis that by term equivalent age, preterm infants have significantly shorter telomeres (thus suggesting that they are prematurely aged. Our results demonstrate that relative telomere length is highly variable in newborn infants and is significantly negatively correlated with gestational age and birth weight in preterm infants. Further, longitudinal assessment in preterm infants who had telomere length measurements available at both birth and term age (n = 5 suggests that telomere attrition rate is negatively correlated with increasing gestational age. Contrary to our initial hypothesis however, relative telomere length was significantly shortest in the term born control group compared to both preterm groups and longest in the preterm at birth group. In addition, telomere lengths were not significantly different between preterm infants sampled at birth and those sampled at term equivalent age. These results indicate that other, as yet undetermined, factors may influence telomere length in the preterm born infant and raise the intriguing hypothesis that as preterm gestation declines, telomere attrition rate increases.

    There is uncertainty about the risk of developmental dysplasia of the hip (DDH) in breech preterm infants and therefore uncertainty about the benefits of using ultrasound screening in this population. The aim of this study was to determine if preterm infants born in the breech position are at risk of DDH. A retrospective audit of preterm and term infants born in the breech position was performed to determine the incidence of DDH. Group 1 included breech preterm infants (positive or negative for DDH. Three out of 129 (2.3%) preterm infants screened had DDH. For term infants, 3 out of 163 (1.8%) infants screened had DDH. The odds ratio for DDH in breech preterm infants compared with breech term infants was 1.27 (95% confidence interval 0.25 to 6.40). Preterm infants born in the breech position appear to have a similar incidence of DDH to term infants and thus require similar screening guidelines. © 2013 The Authors.

    The majority of children who are born very preterm escape major impairment, yet more subtle cognitive and attention problems are very common in this population. Previous research has linked infant focused attention during exploratory play to later cognition in children born full-term and preterm. Infant focused attention can be indexed by sustained decreases in heart rate (HR). However there are no preterm studies that have jointly examined infant behavioral attention and concurrent HR response during exploratory play in relation to developing cognition. We recruited preterm infants free from neonatal conditions associated with major adverse outcomes, and further excluded infants with developmental delay (Bayley Mental Development Index [MDI attention and concurrent HR response were compared in 83 preterm infants (born 23-32 weeks gestational age [GA]) who escaped major impairment to 46 full-term infants. Focused attention and HR response were then examined in relation to Bayley MDI, after adjusting for neonatal risk. MDI did not differ by group, yet full-term infants displayed higher global focused attention ratings. Among the extremely preterm infants born attention episodes, accounted for 49% of adjusted variance in predicting concurrent MDI. There were no significant associations for later-born gestational age (29-32 weeks) or full-term infants. Among extremely preterm infants who escape major impairment, our findings suggest unique relationships between focused attention, HR deceleration, and developing cognition.

    The Sudden Infant Death Syndrome (SIDS) remains the leading cause of death in the post-neonatal period in developed countries (Hauck and Tanabe, 2008). Despite much research, the exact mechanisms underlying SIDS remain unclear, but are thought to involve immature cardiovascular control leading to an uncompensated hypotensive episode, in conjunction with a failure to arouse from sleep (Harper, 2000). The vast majority of SIDS deaths occur within the first six months of life with a distinct p...

    The relationship between periodic breathing and idiopathic apnea of prematurity was investigated. We recorded respiratory impedance, heart rate, pulse oximetry and end-tidal CO2 from 68 untreated infants of less than or equal to 34 wk gestation with a diagnosis of idiopathic apnea of prematurity. Mean birth wt was 1476 g (SD 420) and mean gestational age was 29.9 wk (SD 2.6). Apneas of more than 15 s duration that were associated with hypoxemia or bradycardia were identified by semiautomated analysis of computerized records. A total of 1116 significant apneic spells were identified, only one of which occurred during an epoch of periodic breathing, five others occurred within 2 min of the end of an epoch of periodic breathing. Less than 0.6% of significant apneic spells occur within 2 min of periodic breathing. In all of the 12 infants that were monitored starting in the first 12 h of life, significant apneic spells were identified before 36 h of age and no precipitating factors were identified. Periodic breathing did not occur during the first 48 h of life, a finding that supports the concept that the peripheral chemoreceptor is inactive in the first 48 h of life. Periodic breathing in the premature infant is not a precursor to significant apnea.

    The aim of this study, to determine an index of oxidative stress index in preterm infants less than 34 weeks gestational age with premature preterm rupture of membrane (PPROM) and fetal inflammatory response syndrome (FIRS). This study was designed as a prospective study. Fifty-one premature infants less than 35 weeks of gestational age were included in the study. The umbilical cord blood concentrations of IL-6, TAC (total antioxidant capacity) and PON-1 (paraoxonase-1) levels and TOS (total oxidative stress) were studied. The oxidative stress index (OSI = TAC/TOS) was calculated in all of prematüre infants. PPROM was defined as rupture of membranes at least 24 hours before the onset of labor. FIRS was defined by an umbilical cord IL-6 level greater than 11 pg/mL. Premature infants included in the study were divided into 4 groups. Group 1 included preterm infants without FIRS and with PPROM (n = 16), while Group 2 included preterm infants without PPROM and with FIRS (n = 9), Group 3 consisted of premature infants with PPROM and FIRS (n = 21) and Group 4 included premature infants without PPROM or FIRS (n = 5). Umbilical cord TOS level was found to be higher in the preterm infants without FIRS and with PPROM (36.1 μmol H 2 O 2 Equiv./L) compared to the preterm infants without PPROM or FIRS (11.9 μmol H 2 O 2 Equiv./L) (p = 0.03). Umbilical cord PON-1 level was found to be lower in the preterms without FIRS and with PPROM (32 U/L), preterms without PPROM and with FIRS (30. 3 U/L) and the preterm infants with both PPROM and FIRS (48.6 U/L) compared to the preterm infants having no PPROM or FIRS (85.6 U/L) (p = 0.001). High pro-oxidant capacity was found in PPROM and low antioxidant capacity in PPROM and FIRS. Copyright © 2017. Published by Elsevier B.V.

    Describe the incidence of catheter-related blood stream infection (CRBSI), following removal of peripherally inserted central venous catheters (PICC) in preterm infants. A retrospective cohort study of infants PICC revealed 101 PICCs placed (2159 PICC days). Patients were hospitalized in a level III Neonatal Intensive Care Unit (NICU) between January 2002 and December 2003. Chi(2) analysis was performed. One infection was detected after the removal of a PICC (1 per 202 days). Ten infants had a CRBSI attributed to a PICC (1 per 216 PICC days). CRBSI during indwelling PICC was associated with increased risk for sepsis evaluation after PICC removal (PPICC removal was not different than the incidence of CRBSI while a PICC was in-dwelling. There was no evidence from this study to support antibacterial prophylaxis before PICC removal.

    To determine the epidemiology of congenital and acquired cytomegalovirus (CMV) infections in preterm infants and to analyze the efficacy of breast milk freezing in decreasing the vertical transmission rate of CMV. During 2013 and 2014, preterm newborns who weighed ≤1500 g and were admitted to 22 Spanish neonatal units were included and screened for CMV infection according to the Spanish Neonatology Society recommendations. Each hospital treated the breast milk according to its own protocols. Among the 1236 preterm neonates included, 10 had a congenital infection (0.8%) and 49 had an acquired infection (4.0%) (82% demonstrated positive PCR-CMV in breast milk). The neonates who received only frozen milk presented less frequently with acquired infection (1.2%) than those fed fresh milk (5.5%) (RR=0.22; 95% CI 0.05-0.90; P=0.017). The newborns who received bank milk followed by frozen or fresh breast milk more frequently had an acquired infection (2.1% or 2.2%, respectively) than those fed only frozen breast milk. The incidence of congenital CMV infection in our sample is low, as described in the literature. To reduce acquired CMV infection, freezing breast milk might be an advisable procedure for preterm neonates born from seropositive mothers, either from the beginning of lactation or after a period of bank milk administration.

  20. Carnitine supplementation for preterm infants with recurrent apnea.

    Apnea of prematurity is a common problem in preterm infants in the neonatal intensive care setting (NICU), often delaying their discharge home or transfer to a step down unit. Premature infants are at increased risk of carnitine deficiency. Carnitine supplementation has been used for both prevention and treatment of apnea. To determine whether treatment with carnitine will reduce the frequency of apnea, the duration of ventilation and the duration of hospital stay in preterm infants with recurrent apnea. Computerised searches were carried out by two reviewers independently. Searches were made of MEDLINE (1966 to May 2004), EMBASE (1980 to May 2004), CINAHL (1982-2004 June 2004,1st week), the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 2, 2004), abstracts of annual meetings of the Society for Pediatric Research (1995-2004), and contacts were made with the subject experts. Only randomized or quasi-randomized treatment trials of preterm infants with a diagnosis of recurrent apnea of prematurity were considered. Trials were included if they involved treatment with carnitine compared to placebo or no treatment, and measured at least one of the following outcomes: failure of resolution of apneas, the duration of ventilation and the duration of hospital stay. Two reviewers evaluated the papers for inclusion criteria and quality. Corresponding authors were contacted for further information where needed. No eligible trials were identified. Despite the plausible rationale for the treatment of apnea of prematurity with carnitine, there are insufficient data to support its use for this indication. Further studies are needed to determine the role of this treatment in clinical practice.

    2017-12-01

    Full Text Available IntroductionIntermittent hypoxemia (IH is defined as episodic drops in oxygen saturation (SpO2. Preterm infants are at increased risk for IH due to their immature respiratory control/apnea of prematurity. The clinical relevance of IH is a relatively new observation with rising evidence linking IH to neonatal morbidities and long-term impairment. Hence, assessing factors that influence IH in preterm infants is imperative. Given the epidemic of opioid misuse in the USA, there is an urgent need to understand the impact of prenatal opioid exposure on neonatal outcomes. Hence, we wanted to assess the relationship between isolated prenatal opioid exposure and IH in preterm infants.MethodsIn order to accurately calculate IH, SpO2 data were prospectively collected using high-resolution pulse oximeters during the first 8 weeks of life in preterm infants less than 30 weeks gestational age. Data related to prenatal opioid misuse were retrospectively collected from medical charts. Infants with tobacco or poly-drug exposure were excluded. The primary outcome measure is percent time spent with SpO2 below 80% (%time-SpO2 < 80. The secondary outcome measure is the number of severe IH events/week with SpO2 less than 80% (IH-SpO2 < 80.ResultsA total of 82 infants with isolated opioid exposure (n = 14 or who were unexposed (n = 68 were included. There were no significant differences in baseline characteristics between opioid exposed and unexposed groups. There was a statistically significant increase of 0.23 (95% CI: 0.03, 0.43, p = 0.03 in mean of the square root of %time-SpO2 < 80. The number of IH-SpO2 < 80 events was higher in the opioid exposed group (mean difference = 2.95, 95% CI: −0.35, 6.25, p-value = 0.08, although statistical significance was not quite attained.ConclusionThis study shows that preterm infants prenatally exposed to opioids have increased IH measures compared to unexposed infants.

    Low vagal tone (VT) is a marker of vulnerability to stress and the risk of developing necrotizing enterocolitis in preterm infants. Electric fields produced by equipment in the neonatal intensive care unit (NICU) induce an electric potential measurable on the skin in reference to ground. An electrical connection to ground reduces the skin potential and improves VT in adults. We aimed to measure the electric field strengths in the NICU environment and to determine if connecting an infant to electrical ground would reduce the skin potential and improve VT. We also wished to determine if the skin potential correlated with VT. Environmental magnetic flux density (MFD) was measured in and around incubators. Electrical grounding (EG) was achieved with a patch electrode and wire that extended to a ground outlet. We measured the skin potential in 26 infants and heart rate variability in 20 infants before, during, and after grounding. VT was represented by the high-frequency power of heart rate variability. The background MFD in the NICU was below 0.5 mG, but it ranged between 1.5 and 12.7 mG in the closed incubator. A 60-Hz oscillating potential was recorded on the skin of all infants. With EG, the skin voltage dropped by about 95%. Pre-grounding VT was inversely correlated with the skin potential. VT increased by 67% with EG. After grounding, the VT fell to the pre-grounding level. The electrical environment affects autonomic balance. EG improves VT and may improve resilience to stress and lower the risk of neonatal morbidity in preterm infants. © 2017 S. Karger AG, Basel.

    Objective To test the hypothesis that massage would improve autonomic nervous system (ANS) function as measured by heart rate variability (HRV) in preterm infants. Study Design Medically stable, 29- to 32-week preterm infants (17 massage, 20 control) were enrolled in a masked, randomized longitudinal study. Licensed massage therapists provided the massage or control condition twice a day for 4 weeks. Weekly HRV, a measure of ANS development and function, was analyzed using SPSS generalized estimating equations. Results Infant characteristics were similar between groups. HRV improved in massaged infants but not in the control infants (PMassaged males had a greater improvement in HRV than females (Pmassaged infants was on a trajectory comparable to term-born infants by study completion. Conclusion Massage-improved HRV in a homogeneous sample of hospitalized, medically stable, preterm male infants and may improve infant response to exogenous stressors. We speculate that massage improves ANS function in these infants. PMID:22538325

    Full Text Available Abstract Background Mothers of preterm infants are considered at higher risk for depressive symptoms, higher than for mothers of healthy term infants. Predictors of depressive symptoms in mothers of preterm infants are not yet well established. Immigrant mothers of term infants have higher prevalence of depressive symptoms than Canadian born mothers but the relative prevalence for immigrant mothers of preterm infants is unknown. This study had two aims: (i to investigate the prevalence of depressive symptoms in immigrant as compared to Canadian born mothers of preterm infants, and (ii to determine what factors are associated with depressive symptoms in mothers of preterm infants. Methods This is a multi-site, cross sectional study of mothers whose preterm infants required hospitalization in neonatal intensive care unit (NICU. Consecutive eligible mothers (N = 291 were recruited during the week prior to their infant’s NICU discharge. Mothers completed a self-administered questionnaire booklet of validated psychosocial/cultural measures including the Center for Epidemiological Studies Depression Scale (CES-D, Parental Stressor Scale:NICU, General Functioning Subscale of the McMaster Family Assessment Device, Social Support Index, and Vancouver Index of Acculturation; and demographic characteristics questions. Infant characteristics included gestational age, birth weight, sex, singleton/multiple birth, and Score for Neonatal Acute Physiology-II. Results Immigrant mothers (N = 107, when compared to Canadian born mothers (N = 184, reported more depressive symptoms, poorer family functioning, less social support, and less mainstream acculturation. Hierarchical regression for a subsample of 271 mothers indicated that single parent status, high stress, poorer family functioning, and less social support were associated with increased depressive symptoms and accounted for 39% of the variance on the CES-D. Immigrant status did not contribute

    There is a paucity of studies that have investigated the developmental benefits of positioning in the neonatal intensive care unit. The purpose of this study was to investigate the effects of a new, alternative positioning device compared to traditional positioning methods used with preterm infants. In this randomized, blinded clinical trial, one hundred preterm infants (born ≤32 weeks gestation) from a level III neonatal intensive care unit in the United States were enrolled at birth. Participants were randomized to be positioned in the alternative positioning device or to traditional positioning methods for their length of stay in the neonatal intensive care unit. Infants were assessed using the NICU Network Neurobehavioral Scale at term equivalent age. Clinical and feeding outcomes were also captured. Linear and logistic regression were used to investigate differences in neurobehavioral outcome, feeding performance, and medical outcomes. Infants in the alternative positioning arm of the study demonstrated less asymmetry of reflex and motor responses on the NICU Network Neurobehavioral Scale (p=0.04; Adjusted Mean Difference=0.90, 95% CI 0.05–1.75) than those positioned using traditional positioning methods. No other significant differences were observed. Reductions in asymmetry among preterm infants is an important benefit of alternative positioning, as symmetrical movement and responses are crucial for early development. However, it will be important to follow this sample of preterm infants to determine the effects of early positioning on neurodevelopmental outcome in childhood. PMID:24374602

    Objective: Skin-to-skin contact (SSC) promotes physiological stability and interaction between parents and infants. Analyses of EEG-sleep studies can compare functional brain maturation between SSC and non-SSC cohorts. Methods: Sixteen EEG-sleep studies were performed on eight preterm infants who received eight weeks of SSC, and compared with two non-SSC cohorts at term (N=126), a preterm group corrected to term age and a full term group. Seven linear and two complexity measures were compared (Mann-Whitney U test comparisons p<.05). Results: Fewer REMs, more quiet sleep, increased respiratory regularity, longer cycles, and less spectral beta were noted for SSC preterm infants compared with both control cohorts. Fewer REMs, greater arousals and more quiet sleep were noted for SSC infants compared with the non-SSC preterms at term. Three right hemispheric regions had greater complexity in the SSC group. Discriminant analysis showed that the SSC cohort was closer to the non-SSC full-term cohort. Conclusion: Skin to skin contact accelerates brain maturation in healthy preterm infants compared with two groups without SSC. Significance: Combined use of linear and complexity analysis strategies offer complementary information regarding altered neuronal functions after developmental care interventions. Such analyses may be helpful to assess other neuroprotection strategies. PMID:19766056

    MR imaging of the premature infant poses a number of challenges with regard to safety, sequence optimization and recognition of the normal appearances of the developing brain. In this paper we discuss these challenges, and review the common intracerebral abnormalities associated with premature birth. Although the outcome for very-low-birth-weight babies has improved over the last decade, there remains a significant risk of subsequent development of neurological disability. The relationship between MRI abnormalities and long-term outcome is considered. (orig.)

  9. Caffeine versus theophylline for apnea in preterm infants.

    2010-01-20

    Recurrent apnea is common in preterm infants, particularly at very early gestational ages. These episodes of loss of effective breathing can lead to hypoxemia and bradycardia, which may be severe enough to require resuscitation including use of positive pressure ventilation. Two forms of methylxanthine (caffeine and theophylline) have been used to stimulate breathing in order to prevent apnea and its consequences. To evaluate the effect of caffeine compared with theophylline treatment on the risk of apnea and use of mechanical ventilation in preterm infants with recurrent apnea. The standard search strategy of the Cochrane Neonatal Review Group was used. This included searches of electronic databases in August 2009: Oxford Database of Perinatal Trials; Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 2, 2009); MEDLINE (1966 to April 2009); and EMBASE Drugs and Pharmacology (1990 to April 2009), previous reviews including cross references. Randomized and quasi-randomized trials comparing caffeine to theophylline for treating apnea in preterm infants and reporting effects on apnea event rates. Each author assessed eligibility and trial quality, extracted data separately and compared and resolved differences. Study authors were contacted for additional information. Five trials involving a total of 108 infants were included. The quality of most of these small trials was fair to good. No difference in treatment failure rate (less than 50% reduction in apnea/bradycardia) was found between caffeine and theophylline after one to three days treatment (based on two studies) or five to seven days treatment (based on one study). There was no difference in mean apnea rate between caffeine and theophylline groups after one to three days treatment (based on five trials) and five to seven days treatment (based on four trials).Adverse effects, indicated by tachycardia or feed intolerance leading to change in dosing, were lower in the caffeine

    It has been hypothesized that the association of pacifier use with reduced risk of sudden infant death is mediated by forward movement of the mandible and tongue that helps open the upper airway. Our aim was to examine whether the mandible is moved forward when an infant is sucking on a pacifier, and if so, whether the mandible remains advanced after the pacifier is removed. In sixty clinically stable premature infants (corrected gestation age 36.5 +/- 0.3 weeks, mean +/- SEM) the distance from each ear where the pinna met the cheek to the most prominent point of the chin was measured bilaterally, and the average was used as an index of mandibular position. Mandibular position was determined before and after allowing the infants to suck on a pacifier for 10-15 min, and after removing the pacifier. There was a significant forward movement of the mandible when the infants were sucking on the pacifier (59.5 +/- 0.7 vs. 58.6 +/- 0.7 mm, p = 0.001), with no significant change after the pacifier was removed. Pacifier use in preterm infants was associated with a small significant forward displacement of the jaw. These data suggest that pacifier use may help protect the upper airway.

    Infants who are born preterm have a high incidence of neurocognitive and neurobehavioral abnormalities, which may be associated with impaired brain development. Advanced magnetic resonance imaging (MRI) approaches, such as diffusion MRI (d-MRI) and functional MRI (fMRI), provide objective and reproducible measures of brain development. Indices derived from d-MRI can be used to provide quantitative measures of preterm brain injury. Although fMRI of the neonatal brain is currently a research tool, future studies combining d-MRI and fMRI have the potential to assess the structural and functional properties of the developing brain and its response to injury.

    To explore parents of preterm infants' experiences of caring for their preterm infants with the grandmother as their primary support after discharge. Preterm delivery is the major cause of high neonatal mortality in sub-Saharan Africa. There is poor neonatal health outcome in the Ghanaian community with some illnesses culturally classified as not-for-hospital. In the community, grandmothers or older women provide support for new parents and decide treatment options for sick infants. However, there is paucity of research on how parents of preterm infants experience this support in the Ghanaian community. Qualitative narrative inquiry methodology was used. Face-to-face interviews using semi-structured interview guide were used to collect data from 21 mothers and nine fathers. Participant observation and field notes were used to complement interview data. Thematic content analysis of data within the three-dimensional narrative space was employed. Analysis focussed on the relationship of time, place, person and cultural practices affecting the care of preterm infants in the community. Three themes emerged from the data, namely (i) Grandmother's prescriptions, (ii) Fighting for the well-being of the infant and (iii) Being in a confused state. Cultural practices mainly initiated by grandmothers resulted in adverse health problems for preterm infants and disruption in parents' mental health. As grandmothers perform their traditional role of supporting new parents to care for preterm infants after discharge, they give both positive and negative advice which can adversely affect the health of vulnerable preterm infants in the community. Grandmothers are the main support providers of parents of preterm infants after neonatal unit discharge. Nurses should identify and include grandmothers in predischarge education in order to equip them to render appropriate support to parents and preterm infants. © 2017 John Wiley & Sons Ltd.

    Full Text Available Abstract Background The analysis of perinatal outcomes often involves datasets with some multiple births. These are datasets mostly formed of independent observations and a limited number of clusters of size two (twins and maybe of size three or more. This non-independence needs to be accounted for in the statistical analysis. Using simulated data based on a dataset of preterm infants we have previously investigated the performance of several approaches to the analysis of continuous outcomes in the presence of some clusters of size two. Mixed models have been developed for binomial outcomes but very little is known about their reliability when only a limited number of small clusters are present. Methods Using simulated data based on a dataset of preterm infants we investigated the performance of several approaches to the analysis of binomial outcomes in the presence of some clusters of size two. Logistic models, several methods of estimation for the logistic random intercept models and generalised estimating equations were compared. Results The presence of even a small percentage of twins means that a logistic regression model will underestimate all parameters but a logistic random intercept model fails to estimate the correlation between siblings if the percentage of twins is too small and will provide similar estimates to logistic regression. The method which seems to provide the best balance between estimation of the standard error and the parameter for any percentage of twins is the generalised estimating equations. Conclusions This study has shown that the number of covariates or the level two variance do not necessarily affect the performance of the various methods used to analyse datasets containing twins but when the percentage of small clusters is too small, mixed models cannot capture the dependence between siblings.

It is recommended that KC, as a feasible, natural, and cost-effective intervention, should be standard of care in the delivery of quality health care for all infants, regardless of geographic location or economic status. Numerous benefits of its use have been reported related to mortality, physiological (thermoregulation, cardiorespiratory stability, behavioral (sleep, breastfeeding duration, and degree of exclusivity domains, as an effective therapy to relieve procedural pain, and improved neurodevelopment. Yet despite these recommendations and a lack of negative research findings, adoption of KC as a routine clinical practice remains variable and underutilized. Furthermore, uncertainty remains as to whether continuous KC should be recommended in all settings or if there is a critical period of initiation, dose, or duration that is optimal. This review synthesizes current knowledge about the benefits of KC for infants born preterm, highlighting differences and similarities across low and higher resource countries and in a non-pain and pain context. Additionally, implementation considerations and unanswered questions for future research are addressed. Keywords: kangaroo care, skin-to-skin contact, infant, preterm, review

    Very preterm birth (parenting have the greatest potential to create sustained effects on child development and parental psychopathology. Triple P (Positive Parenting Program) has shown positive effects on child behaviour and adjustment, parenting practices and family functioning. Baby Triple P for Preterm infants, has been developed to target parents of very preterm infants. This study tests the effectiveness of Baby Triple P for Preterm infants in improving child and parent/couple outcomes at 24 months corrected age (CA). Families will be randomised to receive either Baby Triple P for Preterm infants or Care as Usual (CAU). Baby Triple P for Preterm infants involves 4 × 2 hr group sessions at the hospital plus 4 × 30 min telephone consultations soon after transfer (42 weeks C.A.). After discharge participants will be linked to community based Triple P and intervention maintenance up to 24 months C.A. Assessments will be: baseline, post-intervention (6 weeks C.A.), at 12 and 24 months C.A. The primary outcome measure is the Infant Toddler Social & Emotional Assessment (ITSEA) at 24 months C.A. Child behavioural and emotional problems will be coded using the mother-toddler version of the Family Observation Schedule at 24 months C.A. Secondary outcome will be the Bayley Scales of Infant and Toddler Development (BSID III) cognitive development, language and motor abilities. Proximal targets of parenting style, parental self-efficacy, parental mental health, parental adjustment, parent-infant attachment, couple relationship satisfaction and couple communication will also be assessed. Our sample size based on the ITSEA, has 80% power, predicted effect size of 0.33 and an 85% retention rate, requires 165 families are required in each group (total sample of 330 families). This protocol presents the study design, methods and intervention to be analysed in a randomised trial of Baby Triple P for Preterm infants compared to Care as Usual (CAU) for families of very preterm

    Purpose This study’s aim was to explore relationships between preterm infant behavioral outcomes and maternal/infant glucocorticoid (dexamethasone [DEX]) treatments using a psychoneuroimmunologic approach. Research questions were (a) do relationships exist between infant cumulative perinatal steroid (PNS) exposure and child behavioral problems? and (b) do maternal/infant characteristics (e.g., immune markers and biophysiologic stressors) influence these relationships? Methods The convenience sample comprised 45 mother–child dyads in which the children (mean age 8 years ± 2.3) had been born at a mean postconceptional age of 28 weeks (± 4.2). We used the Child Behavior Checklist (CBCL) to assess behavior, the Clinical Risk Index for Babies (CRIB) to score stress at birth, and retrospective record review to identify additional perinatal factors (PNS dosage, sepsis, and maternal and infant complete blood counts near delivery). Results Children were dichotomized into high (> 0.2mg/kg; n = 20) versus low–no (≤ 0.2 mg/kg; n = 25) PNS exposure groups. Significant relationships existed between CBCL Total Problems score and sepsis, PNS exposure, timing of initial PNS, and infant length percentile at discharge. Competence problems were significantly associated with PNS, neonatal intensive care unit (NICU) infant length percentile, CRIB score, sepsis, retinopathy of prematurity, hearing deficit, and immunity markers (i.e., maternal lymphocyte percentage and infant band/seg ratio). Children in the higher PNS group exhibited more behavioral problems (e.g., withdrawn, attention, conduct, social, and rule breaking problems), but there were no significant differences. The findings are reassuring regarding long-term effects of this PNS dose on preterm infant behavioral outcomes. PMID:21900308

    Near-infrared spectroscopy (NIRS) imaging studies have revealed the functional development of the human brain in early infancy. By measuring spontaneous fluctuations in cerebral blood oxygenation with NIRS, we can examine the developmental status of the functional connectivity of networks in the cortex. However, it has not been clarified whether premature delivery and/or chromosomal abnormalities affect the development of the functional connectivity of the cortex. In the current study, we investigated the spontaneous brain activity of sleeping infants who were admitted to a neonatal intensive care unit at term age. We classified them into the 3 following infant groups: (i) term-or-late-preterm, (ii) early-preterm, and (iii) Down's syndrome (DS). We used multichannel NIRS to measure the spontaneous changes in oxygenated hemoglobin (oxy-Hb) and deoxygenated hemoglobin (deoxy-Hb) at 10 measurement channels, which covered the frontal, temporal, and occipital regions. In order to reveal the functional connectivity of the cortical networks, we calculated the temporal correlations of the time-course signals among all of the pairs of measurement channels. The functional connectivity was classified into the 4 following types: (i) short-range, (ii) contralateral-transverse, (iii) ipsilateral-longitudinal, and (iv) control. In order to examine whether the local properties of hemodynamics reflected any pathological conditions, we calculated the phase differences between the oxy- and deoxy-Hb time-course signals in the 3 groups. The statistical analyses of the functional connectivity data showed main effects of group and the types of connectivity. For the group effect, the mean functional connectivity of the infants in the term-or-late-preterm group did not differ from that in the early-preterm group, and the mean functional connectivity of the infants in the DS group was lower than that in the other 2 groups. For the effect of types of connectivity, short-range connectivity

    Cardiovascular instability in preterm infants during the early postnatal period correlates with the development of intraventricular hemorrhage (IVH). Due to the correlation between hypotension and fluctuation of blood pressure, treatment was targeted specifically at hypotension to prevent IVH, but this was not successful. Recently, several novel perfusion markers have been found to be correlated with the development of IVH, and they are of current interest in cardiovascular management. In this review, the correlation between IVH and conventional, as well as novel, perfusion markers is examined. © 2017 Japan Pediatric Society.

    Inadequate nutrient stores at birth are an inevitable consequence of being born prematurely. Preterm infants also have high nutrient requirements, which increase with earlier gestational ages. As a result, early nutrition intervention is required to prevent further deficits that, if not corrected, can affect growth and long-term outcomes. Preterm infants often require several weeks of parenteral nutrition (PN) support, which includes trace mineral supplementation. Trace minerals are considered essential nutrients, unable to be synthesized in the human body. Deficiencies of trace minerals have been reported, yet evidence-based guidelines for assessment and supplementation have not been clearly defined. Food and Drug Administration-approved parenteral trace mineral intake guidelines are more than 30 years old. In an effort to more clearly define trace mineral supplementation and monitoring guidelines for preterm infants, a review of literature was performed with the purpose to (1) summarize trace mineral roles in preterm infants, (2) describe clinical signs of deficiency and toxicity, and (3) present intake recommendations and considerations for preterm infants based on current available literature. Review of literature was completed using PubMed and Cochrane databases to find relevant studies specific to trace mineral requirements for preterm infants, trace mineral supplementation of PN, human milk fortifiers, and preterm infant formulas. Review of literature supports that trace mineral depletion can lead to clinical compromise in preterm infants; therefore, suggesting that every effort be made to ensure adequate provision of trace minerals is given to preterm infants. Practical considerations for the clinical nutrition management of preterm infants were also identified in this review. © 2014 American Society for Parenteral and Enteral Nutrition.

No relation was found between the median total duration of each pattern and injury on cUS and MRI or cognition at 2 and 5 years. Clear ictal discharges are rare in extremely preterm infants. PEDs are common but their significance is unclear. Rhythmic waveforms related to head position are likely artefacts.

    Lack of physical stimulation may contribute to metabolic bone disease of preterm infants, resulting in poor bone mineralization and growth. Physical activity programs combined with adequate nutrition might help to promote bone mineralization and growth. The primary objective was to assess whether physical activity programs in preterm infants improve bone mineralization and growth and reduce the risk of fracture.The secondary objectives included other potential benefits in terms of length of hospital stay, skeletal deformities and neurodevelopmental outcomes, and adverse events.Subgroup analysis:• Given that the smallest infants are most vulnerable for developing osteopenia (Bishop 1999), a subgroup analysis was planned for infants with birth weight mineral content (Kuschel 2004). Therefore, an additional subgroup analysis was planned for infants receiving different amounts of calcium and phosphorus, along with full enteral feeds as follows. ∘ Below 100 mg/60 mg calcium/phosphorus or equal to/above 100 mg/60 mg calcium/phosphorus per 100 mL milk. ∘ Supplementation of calcium without phosphorus. ∘ Supplementation of phosphorus without calcium. The standard search strategy of the Cochrane Neonatal Review Group (CNRG) was used. The search included the Cochrane Central Register of Controlled Trials (CENTRAL) (2012, Issue 9), MEDLINE, EMBASE, CINAHL (1966 to March 2013), and cross-references, as well as handsearching of abstracts of the Society for Pediatric Research and the International Journal of Sports Medicine. Randomized and quasi-randomized controlled trials comparing physical activity programs (extension and flexion, range-of-motion exercises) versus no organized physical activity programs in preterm infants. Data collection, study selection, and data analysis were performed according to the methods of the CNRG. Eleven trials enrolling 324 preterm infants (gestational age 26 to 34 weeks) were included in this review. All were small (N = 16 to 50) single

    Surfactant replacement therapy is crucial in the management of respiratory distress syndrome (RDS) in preterm infants. Classic strategies of surfactant administration required intubation. To reduce the need of intubation and mechanical ventilation (MV), we applied surfactant via a thin endotracheal catheter without intubation. We compared 26 preterm infants threatened by RDS treated with surfactant via a thin endotracheal catheter without intubation (studied group - SG) with a retrospective group of preterm infants managed on MV with early surfactant treatment using INtubation SURfactant Extubation (INSURE) method (control group - CG). Study had an approval from the ethics committee (RNN/6/14/KE). In the SG, 26 preterm infants were treated with one dose of surfactant (Curosurf®) administered via endotracheal catheter without intubation while receiving nasal continuous positive airway pressure (nCPAP)/SiPAP (Infant Flow). After surfactant administration, significantly less patients in SG required intubation and MV (19.2%) versus 65% necessity of second intubation in the CG. The median of time of MV in SG was 5 d versus 3.5 d in CG. Median time spent on nCPAP was 5.5 d versus 4.0 d in CG. The incidence of intraventricular hemorrhage (IVH) in the SG was 53.9%, including 50% with ≥ IVH II versus 36.7% (30% ≥ IVH II) in CG. The incidence of other complications of prematurity in the SG, such as necrotizing enterocolitis was 11.5% versus 23.3% in CG, the hemodynamically important patent ductus arteriosus was observed in 53.9% in SG versus 45% in CG. Bronchopulmonary dysplasia level in SG was significantly lower (15.4%) than in CG (40%), and the incidence of retinopathy of prematurity in SG was also lower (3.9%) versus 11.7% in MV group. Surfactant application via a thin endotracheal catheter without intubation seems to be a beneficial therapy for preterm infants with slight and mild degree of RDS. This new method of surfactant application was associated with a lower

    In 2006 the apnea of prematurity (AOP) consensus group identified inaccurate counting of apnea episodes as a major barrier to progress in AOP research. We compare nursing records of AOP to events detected by a clinically validated computer algorithm that detects apnea from standard bedside monitors. Waveform, vital sign, and alarm data were collected continuously from all very low-birth-weight infants admitted over a 25-month period, analyzed for central apnea, bradycardia, and desaturation (ABD) events, and compared with nursing documentation collected from charts. Our algorithm defined apnea as > 10 seconds if accompanied by bradycardia and desaturation. Of the 3,019 nurse-recorded events, only 68% had any algorithm-detected ABD event. Of the 5,275 algorithm-detected prolonged apnea events > 30 seconds, only 26% had nurse-recorded documentation within 1 hour. Monitor alarms sounded in only 74% of events of algorithm-detected prolonged apnea events > 10 seconds. There were 8,190,418 monitor alarms of any description throughout the neonatal intensive care unit during the 747 days analyzed, or one alarm every 2 to 3 minutes per nurse. An automated computer algorithm for continuous ABD quantitation is a far more reliable tool than the medical record to address the important research questions identified by the 2006 AOP consensus group.

    Full Text Available OBJECTIVE: To evaluate intraocular pressure in very low birth weight preterm infants and correlate it with postconceptional age. METHODS: The intraocular pressure in a prospective cohort of very low birth weight premature infants (defined as a birth weight <1,500 g and gestational age <32 weeks admitted to Hospital de Clínicas de Porto Alegre , Brazil was evaluated weekly. The evaluated outcome was the variation in the intraocular pressure following changes in the postconceptional age (defined as the gestational age at birth plus the age in weeks at the time of examination in the weeks following preterm birth. Mixed-effects models were used for the statistical analysis to determine the intraocular pressure variation according to postconceptional age, and means and 10th and 90th percentiles were calculated for the intraocular pressure values. RESULTS: Fifty preterm infants with a mean gestational age of 29.7 ± 1.6 weeks and a mean birth weight of 1,127.7 ± 222.7 g were evaluated. The mean intraocular pressure for the entire cohort considering both eyes was 14.9 ± 4.5 mmHg, and 13.5% of all recorded intraocular pressure values were greater than 20 mmHg. The analysis revealed a mean reduction in the intraocular pressure of 0.29 mmHg for each increase in postconceptional age (p = 0.047; 95% CI: -0.58 to -0.0035. The mean intraocular pressure (P10-P90 decreased from 16.3 mmHg (10.5222.16 at 26.3 weeks to 13.1 mmHg (7.28-18.92 at 37.6 weeks of postconceptional age. CONCLUSIONS: The mean intraocular pressure in very low birth weight preterm infants was 14.9 ± 4.5 mmHg. This value decreased 0.29 mmHg per week as the postconceptional age increased.

    Full Text Available Background: Bathing of a premature newborn is important in care giving, but due to inadequate evidences, infant caregivers are not sure about bathing being safe in terms of not causing hypothermia and are not systematically considered in the infants’ care giving programs. Aim: To determine the effect of tub bathing on body temperature of preterm infants”. Methods: This study is a randomized controlled clinical trial which was conducted in 1392 in neonatal unit of Al-zahra hospital. 118 preterm infants were randomly divided into intervention and control groups. The infants in the control group received routine skin care only. The intervention group was bathed three times every other day inside the bathtub. In both group, the infants’ body temperature was measured at the same times by the researcher. Data were analyzed with SPSS software version 14 using independent T-test, Chi-square and repeated measurements tests. Results: In both groups, boys outnumbered girls. At the time of inclusion, the infants' age was 5.8 ± 8.6 days and their weight was 320.6 ± 1660.0 grams. In both groups, the mean temperature of premature infants after bath was dropped in all three times. Which was statistically significant in the first and second baths (P

    OBJECT Posthemorrhagic hydrocephalus (PHH) in the preterm infant remains a major neurological complication of prematurity. The authors first described insertion of a specially designed low-profile subcutaneous ventricular catheter reservoir for temporary management of hydrocephalus in 1983. This report presents the follow-up experience with the surgical management of PHH in this population and describes outcomes both in infants who were stable for permanent shunt insertion and those initially temporized with a ventricular reservoir (VR) prior to permanent ventriculoperitoneal (VP)/ventriculoatrial (VA) shunt placement. METHODS A retrospective review was undertaken of the medical records of all premature infants surgically treated for posthemorrhagic hydrocephalus (PHH) between 1997 and 2012 at Children's Hospital Los Angeles. RESULTS Over 14 years, 91 preterm infants with PHH were identified. Fifty neonates received temporizing measures via a VR that was serially tapped for varying time periods. For the remaining 41 premature infants, VP/VA shunt placement was the first procedure. Patients with a temporizing measure as their initial procedure had undergone CSF diversion significantly earlier in life than those who had permanent shunting as the initial procedure (29 vs 56 days after birth, p hydrocephalus and shunt infection did not statistically differ between the 2 groups. CONCLUSIONS Patients with initial VR insertion as a temporizing measure received a CSF diversion procedure significantly earlier than those who received a permanent shunt as their initial procedure. Otherwise, the outcomes with regard to shunt revisions, loculated hydrocephalus, and shunt infection were not different for the 2 groups.

    Full Text Available Objective: To evaluate the effect of recorded music with multimodal stimulation on the weight gain of preterm infants included in the Kangaroo-Mother Program. Methods: Randomized clinical trial with 61 premature infants, of both sexes, with postconceptional age greater or equal to 32 weeks and at least ten days of life, without detected abnormalities in the visual and hearing systems, and hospitalized in the Kangaroo-Mother Unit. Patients were randomized in two groups: of 31 preterm infants received multimodal stimulation with music daily, for seven days; 30 preterm infants received only multimodal stimulation. The following characteristics were evaluated: weight gain, energy consumption, heart rate and respiratory rate, stress signs and feeding method. Comparison between groups was made by Student’s t-test, Mann Whitney test and chi-square test, being significant p<0.05. Results: The two groups did not present significant differences in relation to the feeding method and energy consumption (p=0.46; however, weight gain was greater in the Experimental Group (p=0.002, which also presented better stability in cardiac and respiratory rates (p<0.001 and a significant reduction of stress signs (p=0.007, compared with the Control Group. Conclusions: The recorded music with multimodal stimulation is associated with a greater gain in body weight of hospitalized preterm infants as well as presents a positive influence on vital and stress signs (Clinical Trials Registry - UTN: U1111-1153-9301.

    BackgroundHuman milk has a high content of the antimicrobial compound hydrogen peroxide (H 2 O 2 ). As opposed to healthy full-term infants, preterm neonates are fed previously expressed and stored maternal milk. These practices may favor H 2 O 2 decomposition, thus limiting its potential benefit to preterm infants. The goal of this study was to evaluate the factors responsible for H 2 O 2 generation and degradation in breastmilk.MethodsHuman donors' and rats' milk, along with rat mammary tissue were evaluated. The role of oxytocin and xanthine oxidase on H 2 O 2 generation, its pH-dependent stability, as well as its degradation via lactoperoxidase and catalase was measured in milk.ResultsBreast tissue xanthine oxidase is responsible for the H 2 O 2 generation and its milk content is dependent on oxytocin stimulation. Stability of the human milk H 2 O 2 content is pH-dependent and greatest in the acidic range. Complete H 2 O 2 degradation occurs when human milk is maintained, longer than 10 min, at room temperature and this process is suppressed by lactoperoxidase and catalase inhibition.ConclusionFresh breastmilk H 2 O 2 content is labile and quickly degrades at room temperature. Further investigation on breastmilk handling techniques to preserve its H 2 O 2 content, when gavage-fed to preterm infants is warranted.

    Treating anemia of prematurity is transfused red blood cells and the use of erythropoiesis-stimulating agents. The aim of this article is to determine the correlation between the number of blood transfusions and the use of recombinant human erythropoietin in preterm infants with anemia. A correlation study was performed in 80 cases of patients with anemia treated with transfusions and erythropoietin, were randomized into two groups: one was treated with transfusions (T) and one with transfusions and erythropoietin (E). Demographic variables, hemoglobin and hematocrit at the beginning and end of treatment and number of transfusions received were measured. The correlation was obtained through Spearman Rho, considering p infants with anemia. Its use does not preclude the transfusion, the patient remains exposed to the risk of communicable diseases in this way.

    Although continuous positive airway pressure is used extensively in neonatal intensive care units, and despite the belief that positioning is considered vital to the maintenance of good lung ventilation, no data exist on regional ventilation distribution in infants on continuous positive airway pressure ventilatory support. To investigate the effect of body position on regional ventilation in preterm infants on continuous positive airway pressure ventilatory support using electrical impedance tomography. Randomized crossover study design. Neonatal intensive care unit. Twenty-four preterm infants on continuous positive airway pressure were compared to six spontaneously breathing preterm infants. Random assignment of the order of the positions supine, prone, and quarter prone. Changes in global and regional lung volume were measured with electrical impedance tomography. Although there were no differences between positions, regional tidal volume was increased in the posterior compared with the anterior lung (p positive airway pressure. The posterior lung filled earlier than the anterior lung in the spontaneously breathing infants (p positive airway pressure the right lung filled before the left lung (p positive airway pressure than in the healthy infants (p preterm infants on continuous positive airway pressure using electrical impedance tomography. Gravity had little impact on regional ventilation distribution in preterm infants on continuous positive airway pressure or in spontaneously breathing infants in the supine or prone position, indicating that ventilation distribution in preterm infants is not gravity-dependent but follows an anatomical pattern.

    To investigate the effect of caffeine citrate treatment on early pulmonary function in preterm infants with apnea. Forty preterm infants with apnea were randomly divided into aminophylline treatment group (20 infants) and caffeine citrate treatment group (20 infants). When the preterm infants experienced apnea after birth, they were given aminophylline or caffeine citrate in addition to assisted ventilation with continuous positive airway pressure (NCPAP). After drug discontinuation, pulmonary function was measured and compared between the two groups. After treatment, compared with the aminophylline treatment group, the caffeine citrate treatment group had significantly higher tidal volume, minute ventilation volume, ratio of time to peak tidal expiratory flow to total expiratory time, ratio of volume to peak tidal expiratory flow to total expiratory volume, peak expiratory flow, and breathing flow at 75%, 50%, and 25% of tidal volume (Papnea attacks (Papnea in preterm infants, caffeine citrate can improve early pulmonary function and reduce the incidence of apnea.

    Studies on possible sociodemographic inequities in the survival of preterm infants are scarce. Individual and neighbourhood sociodemographic factors are related to preterm birth and to infant mortality in full-term infants. The aim here was to examine whether infant mortality in Swedish preterm infants is related to individual and neighbourhood sociodemographic factors, and to study whether the hypothesised association between neighbourhood deprivation and infant mortality persists after accounting for individual sociodemographic factors. The study included 46,470 infants with a gestational length of Sweden between 1992 and 2006. Neighbourhood deprivation was assessed by an index (education, income, unemployment, welfare assistance) in small geographical units, and categorised into low, moderate and high deprivation. Adjusted odds ratios for infant mortality were examined in relation to individual and neighbourhood sociodemographic factors. After adjusting for maternal age, infant mortality was associated with the following sociodemographic variables: maternal non-married/non-cohabiting status, low family income, low maternal education and rural status. After full adjustment, the odds ratio [95% confidence interval] was 2.98 [2.42, 3.67] for low family income compared with high family income. An increase in infant mortality was also associated with high neighbourhood deprivation; however, this increased risk no longer remained statistically significant after adjusting for individual sociodemographic factors. In conclusion, this study showed an increased infant mortality in preterm infants born to women with a less favourable sociodemographic profile. © 2011 Blackwell Publishing Ltd.

    Full Text Available Background: Retinopathy of prematurity (ROP is the main cause of visual impairment in preterm newborn infants. Objective: This study was conducted to determine whether insulin-like growth factor binding protein -3 (IGFBP-3 is associated with proliferative ROP and has a role in pathogenesis of the disease in premature infants. Materials and Methods: A total of 71 preterm infants born at or before 32 weeks of gestation participated in this study. Studied patients consisted of 41 neonates without vaso-proliferative findings of ROP as the control group and 30 preterm infants with evidence of severe ROP in follow up eye examination as the case group. Blood samples obtained from these infants 6-8 weeks after birth and blood levels of IGFBP-3 were measured using enzyme-linked immunosorbent assay (ELISA. Results: The mean gestation age and birth weight of the studied patients were 28.2±1.6 weeks and 1120.7±197 gram in the case group and 28.4±1.6 weeks and 1189.4±454 gram in the control group (P=0.25 and P=0.44 respectively. The infants in the case group had significantly lower Apgar score at first and 5 min after birth. Insulin-like growth factor binding protein -3 (IGFBP-3 was significantly lower in the patients with proliferative ROP than the patients without ROP [592.5±472.9 vs. 995.5±422.2 ng/ml (P=0.009]. Using a cut-off point 770.45 ng/ml for the plasma IGFBP-3, we obtained a sensitivity of 65.9% and a specificity of 66.7% in the preterm infants with vasoproliferative ROP. Conclusion: Our data demonstrated that the blood levels IGFBP-3 was significantly lower in the patients with ROP and it is suspected that IGFBP-3 deficiency in the premature infants may have a pathogenetic role in proliferative ROP.

    Preterm birth is associated with long-term deficits in executive functioning and cognitive performance. Using the model of brain plasticity as a theoretical framework, it is possible that preterm infants' neurodevelopmental sequelae can be altered. Evidence suggests that bilingualism confers cognitive advantages on executive functioning, so it is possible that bilingualism may improve preterm infants' neurodevelopment. However, bilingualism has only been studied in term children. This review examined literature that compared the performance of preterm-born children to term children and bilingual children to monolingual children on executive function tasks. To address cognitive disparities in preterm-born children, studies investigating the effect of bilingualism on preterm infants' executive functioning is warranted.

    Only a few studies have been conducted with the objective of creating norms of the Alberta Infant Motor Scale (AIMS) for the assessment of gross motor development of preterm infants. The AIMS performance of preterm infants has been compared with that of the Canadian norms of full-term infants, but not with that of full-term infants of the same nationality. Moreover, the possible impact of prematurity-related morbidity factors on AIMS performance is unknown. The aims of this study were: (1) to evaluate AIMS trajectory in a large population of Greek preterm infants and create norms, (2) to compare it with the AIMS trajectory of Greek full-term infants, and (3) to examine the possible influence of neonatal morbidity on AIMS scores in the preterm sample. This was a cross-sectional study. Mean AIMS scores were compared, per month (1-19), between 403 preterm infants (≤32 weeks of age, corrected for prematurity) and 1,038 full-term infants. In preterm infants, the association of AIMS scores with respiratory distress syndrome (RDS), intraventricular hemorrhage (IVH) of grade ≤III, bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), and sepsis was assessed by hierarchical regression analysis. Alberta Infant Motor Scale scores were significantly lower in preterm infants than in full-term infants. Mean AIMS scores in preterm infants were significantly associated with RDS (b=-1.93; 95% CI=-2.70, -1.16), IVH (b=-0.97; 95% CI=-1.69, -0.25), and ROP (b=-1.12; 95% CI=-1.99, -0.24) but not with BPD or sepsis in hierarchical regression analysis. Alberta Infant Motor Scale norms were created for Greek preterm infants. This study confirms that AIMS trajectories of preterm infants are below those of full-term infants of the same nationality. The influence of morbidity factors, including RDS, IVH, and ROP, should be taken into account when administering the AIMS in preterm infants. © 2016 American Physical Therapy Association.

    This pilot study was conducted to compare the effectiveness of the kangaroo care method with current, mainly incubator-based care in managing well preterm infants in a tertiary level hospital in a developing country. Altogether, 74 infants (37 per group) were consecutively allocated to receive either kangaroo care or incubator care. After adjusting for age and weight on admission to the study, we found that infants in the kangaroo care group gained twice as much weight per day (20.8 vs 10.2 g, p = 0.0001), had a shorter stay in hospital (16.6 vs 20.7 days, p = 0.0457) and had a better survival rate (0% vs 9% deaths). Also, they were ill less frequently, but after adjusting for age and weight this difference was not significant. This pilot study suggests that the kangaroo care method has major advantages over incubator care of preterm infants in our hospital. Hospitals which cannot use incubators optimally may find kangaroo care to be a better method of improving perinatal and neonatal morbidity and mortality.

    Full Text Available Mother’s own milk is widely recognized as the optimal feeding not only for term but also for preterm infants. Evidence documents short and long-term metabolic, immunologic and neurodevelopmental advantages of breastfeeding when compared to formula. Moreover benefits of breastfeeding on psychological and relational aspects have to be considered. In order to meet the unique nutritional requirements of preterm infants and preserve the singular benefit of breastfeeding, human milk should be fortified to allow adequate growth and bone mineralization. Best fortification models are still object of research, in order to obtain a balance between the risk of undernutrition and the metabolic risks of a too rapid catch-up growth. When mother milk is unavailable or in short supply, donor milk (DM represents the second best alternative and although some nutritional elements are inactivated by the pasteurization process, it still has documented advantages compared to formula. The demonstrated benefits of human milk (HM highlight the importance of health care professional education in the support of breastfeeding.

    Full Text Available Respiratory distress syndrome (RDS represents one of the major causes of mortality among preterm infants, and the best approach to treat it is an open research issue. The use of perfluorocarbons (PFC along with non-invasive respiratory support techniques has proven the usefulness of PFC as a complementary substance to achieve a more homogeneous surfactant distribution. The aim of this work was to study the inhaled particles generated by means of an intracorporeal inhalation catheter, evaluating the size and mass distribution of different PFC aerosols. In this article, we discuss different experiments with the PFC perfluorodecalin (PFD and FC75 with a driving pressure of 4–5 bar, evaluating properties such as the aerodynamic diameter (Da, since its value is directly linked to particle deposition in the lung. Furthermore, we develop a numerical model with computational fluid dynamics (CFD techniques. The computational results showed an accurate prediction of the airflow axial velocity at different downstream positions when compared with the data gathered from the real experiments. The numerical validation of the cumulative mass distribution for PFD particles also confirmed a closer match with the experimental data measured at the optimal distance of 60 mm from the catheter tip. In the case of FC75, the cumulative mass fraction for particles above 10 µm was considerable higher with a driving pressure of 5 bar. These numerical models could be a helpful tool to assist parametric studies of new non-invasive devices for the treatment of RDS in preterm infants.

    Supine sleep positioning (SSP) has been shown to reduce the risk of sudden infant death syndrome (SIDS) and preterm infants are at higher risk for SIDS. Population-based estimates of SSP are lacking for the preterm population. The objectives of this study are: (1) compare the prevalence of SSP after hospital discharge for preterm and term infants in the United States; and (2) assess racial/ethnic disparities in SSP for preterm and term infants. We analyzed the 2000 to 2011 data from the Pregnancy Risk Assessment Monitoring System of Centers for Disease Control and Prevention from 35 states. We measured prevalence of SSP by preterm and term gestational age (GA) categories. We calculated adjusted prevalence ratios (APR) to evaluate the likelihood of SSP for each GA category compared with term infants and the likelihood of SSP for non-Hispanic black (NHB) and Hispanic infants compared with non-Hispanic white (NHW) infants. Prevalence of SSP varied by GA: ⩽27, 59.7%; 28 0/7 to 33 6/7, 63.7%; 34 0/7 to 36 6/7 (late preterm), 63.6%; and 37 0/7 to 42 6/7 (term) weeks, 66.8% (Ppreterm infants were slightly less likely to be placed in SSP compared with term infants (APR: 0.96, confidence interval: 0.95 to 0.98). There were racial/ethnic disparities in SSP for all GA categories when NHB and Hispanic infants were compared with NHW infants. All infants had suboptimal adherence to SSP indicating a continued need to better engage families about SSP. Parents of late preterm infants and families of NHB and Hispanic infants will also require greater attention given their decreased likelihood of SSP.

    Radionuclide lumbar cisternography using indium 111-diethylenetriamine pentaacetic acid (111In-DTPA) and a mobile gamma-camera with a converging collimator was utilized as a bedside procedure to evaluate CSF dynamics and the patency of the cerebral ventricular system in 30 preterm infants with hydrocephalus. Serial images of the brain were obtained at 0, 1, 2, 6, 24, and 48 hours after instillation of the isotope in the lumbar subarachnoid space. Three distinct patterns were seen. Infants with posthemorrhagic hydrocephalus displayed prompt ventricular filling but markedly delayed emptying with minimal flow over the cerebral convexities. Infants with ventriculomegaly secondary to suspected brain atrophy or periventricular leukomalacia demonstrated a pattern of prompt ventricular filling, delayed emptying, but with flow present over the convexities. An infant with noncommunicating hydrocephalus secondary to an Arnold-Chiari malformation showed a pattern of complete obstruction with no ventricular filling. Radionuclide lumbar cisternography appears to be a safe, well-tolerated procedure which produces images of sufficient resolution to provide valuable information about CSF dynamics, delineating basal cisternae, ventricles, and subarachnoid flow paths.

    The early anemia in preterm infants, usually implies as a remedy, the use of erythrocyte transfusions indicated according to transfusion criteria which are variable from one neonatal center to another. To evaluate our practice of transfusions concerning the anemia in preterm infants. A descriptive study on 113 preterm infants whose gestational age is Infants Hospital at Rabat during the year 2006, by recording the gestational age, the weight at birth, the rate of haemoglobin and hematocrit at the first admission of the infant and before his first blood transfusion and finally the clinical and biological indications. In order to analyse the criteria of blood transfusion, we have compared between two groups: a group A of 65 transfused preterm infants and a group B of 48 non-transfused with the test of Chi2 and t Student at threshold of P infants were transfused. The preterm babies who has received transfusion compared to those who have not, are significantly more preterm, their weight at birth is weak and the time of hospitalisation is longer, having had more nosocomial infections, postnatal bleeding and their haemoglobin and hematocrit rate at birth is lower (P infants had presented clinical signs of anemia and had been transfused one week earlier than asymptomatic infants and had elevated rates of haemoglobin and hematocrit (P < 0,005). The use of blood transfusion is frequent in our context and implies preventive measures to reduce it.

  12. Assessment of cardiorespiratory stability using the infant car seat challenge before discharge in preterm infants (<37 weeks' gestational age).

    2016-04-01

    Preterm infants younger than 37 weeks corrected gestational age are at increased risk for abnormal control of respiration. The infant car seat challenge has been used as a screening tool to ensure cardiorespiratory stability before discharging preterm infants from many hospitals in Canada. While it is clear that infants placed in a car seat are more likely to experience oxygen desaturation and/or bradycardia than when they are supine, neither positioning predicts an adverse neurodevelopmental outcome or mortality post-discharge. A review of the literature yielded insufficient evidence to recommend routine use of the infant car seat challenge as part of discharge planning for preterm infants. This finding has prompted a change in recommendation from a previous Canadian Paediatric Society position statement published in 2000.

    Preterm birth is associated with increased risk of neurological impairment and deficits in cognition, motor function, and behavioral problems. Limited studies indicate that multi-sensory experiences support brain development in preterm infants. Music appears to promote neurobiological processes and neuronal learning in the human brain. Creative music therapy (CMT) is an individualized, interactive therapeutic approach based on the theory and methods of Nordoff and Robbins. CMT may promote brain development in preterm infants via concurrent interaction and meaningful auditory stimulation. We hypothesize that preterm infants who receive creative music therapy during neonatal intensive care admission will have developmental benefits short- and long-term brain function. A prospective, randomized controlled single-center pilot trial involving 60 clinically stable preterm infants under 32 weeks of gestational age is conducted in preparation for a multi-center trial. Thirty infants each are randomized to either standard neonatal intensive care or standard care with CMT. Music therapy intervention is approximately 20 min in duration three times per week. A trained music therapist sings for the infants in lullaby style, individually entrained and adjusted to the infant's rhythm and affect. Primary objectives of this study are feasibility of protocol implementation and investigating the potential mechanism of efficacy for this new intervention. To examine the effect of this new intervention, non-invasive, quantitative magnetic resonance imaging (MRI) methods at corrected age and standardized neurodevelopmental assessments using the Bayley Scales of Infant and Toddler Development third edition at a corrected age of 24 months and Kaufman Assessment Battery for Children at 5 years will be performed. All assessments will be performed and analyzed by blinded experts. To our knowledge, this is the first randomized controlled clinical trial to systematically examine possible

    Introduction: Although the survival rate of infants born preterm has increased, the prevalence of developmental problems and motor disorders among this population of infants remains the same. This study investigated the effect of physical activity programs in and out of water on motor performance and neuromuscular development of infants born preterm and had induced immobility by mechanical ventilation. Methods: This study was carried out in Al-Zahra hospital, Tabriz. 76 premature infants were randomly assigned into four groups. One group received daily passive range of motion to all extremities based on the Moyer-Mileur protocol. Hydrotherapy group received exercises for shoulders and pelvic area in water every other day. A combination group received physical activity programs in and out of water on alternating days. Infants in a containment group were held in a fetal position. Duration of study was two weeks 'from 32 through 33 weeks post menstrual age (PMA). Motor outcomes were measured by the Test of Infant Motor Performance. Neuromuscular developmental was assessed by New Ballard scale and leg recoil and Ankle dorsiflexion items from Dubowitz scale. Data were analyzed using SPSS version 13. Results: TIMP and neuromuscular scores improved in all groups. Motor performance did not differ between groups at 34 weeks PMA. Postural tone of leg recoil was significantly higher in physical activity groups post intervention. Conclusion: Physical activities and containment didn't have different effects on motor performance in infants born preterm. Leg recoil of neuromuscular development items was affected by physical activity programs.

    The individual motor elements presumed to be essential for motor development were determined from spontaneous movements involving the entire body of normal term and preterm infants. Then, diagnostic items for motor abnormality in infants with periventricular leukomalacia (PVL) were investigated. Video recordings of 24 healthy term infants, 21 normal preterm infants (8 males, 13 females; median gestational age 30 weeks; median birth weight 1216g) and 14 preterm infants with PVL (6 males, 8 females; median gestational age 30 weeks; median birth weight 1360g) were analyzed. In healthy term infants, predominant shoulder rotation was noticed until 1 month of age. After 2 months of age, isolated movements of the shoulder, elbow, hip, knee, and ankle frequently emerged. In preterm infants with PVL at the corrected age of 2 months, startle response and predominant shoulder rotation were more frequently seen and isolated neck, shoulder, elbow, hip, knee, and ankle movements were less frequently seen than in the normal preterm infants (Fisher's exact test, p<0.025). At 2 months of age, isolated movements evolve, and their failure to occur is suggested to be a useful sign for the diagnosis of cerebral motor disorders.

  19. A comparison between preterm and full-term infants' preference for faces

    Directory of Open Access Journals (Sweden)

    Silvana A. Pereira

    Full Text Available Abstract: Objective: Visual preference for faces at birth is the product of a multimodal sensory experience experienced by the fetus even during the gestational period. The ability to recognize faces allows an ecologically advantageous interaction with the social environment. However, perinatal events such as premature birth, may adversely affect the adequate development of this capacity. In this study, we evaluated the preference for facial stimuli in preterm infants within the first few hours after birth. Methods: This is a cross-sectional observational study of 59 newborns, 28 preterm and 31 full-term infants. The babies were assessed in the first hours of life, with two white boards in the shape of a head and neck: one with the drawing of a face similar to the human face (natural face, and one with the drawing of misaligned eyes, mouth and nose (distorted face. After the newborn fixated the eyes on the presented stimulus, it was slowly moved along the visual field. The recognition of the stimulus was considered present when the baby had eye or head movements toward the stimulus. Results: The preterm infants, in addition to showing a lower occurrence of orientation movements for both stimuli, on average (1.8 ± 1.1 to natural faces and 2.0 ± 1.2 for distorted ones also showed no preference for any of them (p = 0.35. Full-term newborns showed a different behavior, in which they showed a preference for natural faces (p = 0.002 and a higher number of orientations for the stimulus, for both natural (3.2 ± 0.8 and distorted faces (2.5 ± 0.9. Conclusion: Preterm newborns recognize facial stimuli and disclose no preference for natural faces, different from full-term newborns.

    Full Text Available Abstract Introduction Humans in the last trimester of gestation are assumed to be in a pain-free environment in the womb, but those neonates who are born preterm often spend weeks in the Neonatal intensive care unit (NICU and undergo numerous painful procedures as part of their routine care. Materials and Methods In this semi-experimental study, 70 preterm infants born at average 32 to 36 weeks' Gestational age (GA, who needed routine blood collection, were allocated to two intervention (35 neonates and control (35 neonates groups. In experimental group a nurse held the infant in the side-lying, flexed fetal-type position during blood collection. The stopwatch was used to determine the duration of crying infants. The control group did not receive additional action for pain relief. Data were analyzed by using SPSS version 16 software. Results The mean age of infants was 34.45 ± 1.22 weeks. The results showed that the duration of crying after sampling in the two groups was statistically significant difference, this duration in control group was higher than the intervention group (P

    Full Text Available Background. Caffeine is widely used to treat apnea of prematurity. Here, we evaluated the efficacy of early caffeine (1-2 DOL in decreasing the incidence of adverse neonatal outcomes. Methods. A retrospective cohort was used to compare the neonatal morbidity of 150 preterm neonates with gestational age ≤29 weeks. Infants were divided into 3 groups based on the initiation timing of caffeine therapy; (1 early caffeine (1-2 DOL, (2 late caffeine (3–7 DOL, and (3 very late caffeine (≥8 DOL. Results. The neonatal outcomes of early caffeine were comparable with those of the late caffeine group. Moreover, when comparing the neonatal morbidity of the very late caffeine group with that of the early caffeine group, multivariable logistic regression analyses were performed. We found that the timing of caffeine did not influence the risk of BPD (OR, 0.393; CI, 0.126–1.223; p=0.107, but birthweight did (OR, 0.996; CI, 0.993–0.999; p=0.018 in these infants. Conclusion. Neonatal outcomes of preterm infants were comparable whether caffeine was administered early or late in the first 7 DOL. The risk of BPD in infants receiving caffeine after 8 DOL was irrespective of delayed treatment with caffeine. Our results clearly demonstrate the need for further studies before caffeine prophylaxis can be universally recommended.

    Optimal nutrition is of utmost importance for the preterm infant's later health and developmental outcome. Amino acid requirements for preterm infants differ from those for term and older infants, because growth rates differ. Some nonessential amino acids, however, cannot be sufficiently synthesized endogenously. Cyst(e)ine is supposed to be such a conditionally essential amino acid in preterm infants. The objective of this study was to determine, at 32 and 35 weeks' postmenstrual age, cyst(e)ine requirements in fully enterally fed very low birth weight preterm infants with gestational ages of ine requirement was determined with the indicator amino acid oxidation technique ([1-(13)C]phenylalanine) after 24-hour adaptation. Fractional [1-(13)C]phenylalanine oxidation was established in 47 very low birth weight preterm infants (mean gestational age: 28 weeks +/- 1 week SD; birth weight: 1.07 kg +/- 0.21 kg SD). Increase in dietary cyst(e)ine intake did not result in a decrease in fractional [1-(13)C]phenylalanine oxidation. These data do not support the hypothesis that endogenous cyst(e)ine synthesis is limited in very low birth weight preterm infants with gestational ages of ine requirement is ine is probably not a conditionally essential amino acid in these infants.

  3. Targeting inflammation in the preterm infant: The role of the omega-3 fatty acid docosahexaenoic acid

    Full Text Available Long-chain polyunsaturated fatty acids are critical for the normal growth and development of preterm infants. Interest in these compounds rests in their anti-inflammatory properties. Clinical conditions with an inflammatory component such as bronchopulmonary dysplasia, necrotising enterocolitis and sepsis are risks to the survival of these infants. Dysregulation of inflammatory responses plays a central role in the aetiology of many of these neonatal disorders. There is evidence to suggest that the omega-3 long chain polyunsaturated fatty acid docosahexaenoic acid (DHA can down-regulate local and systemic inflammation in adults and animal models; however, very little is known about its protective effects in infants, especially preterm infants. Due to their immunological immaturity, preterm infants are particularly sensitive to diseases with an inflammatory aetiology in the early postnatal period. This makes DHA supplementation immediately after birth to combat neonatal inflammation an attractive therapy. Mechanistic data for DHA use in preterm infants are lacking and results from adult and animal studies may not be relevant to this population because of fundamental immune system differences. While there is increasing evidence from randomised controlled trials to support a beneficial effect of DHA for the preterm infant, more evidence is required to establish short and long-term effects of DHA on the immune status of preterm infants.

    Full Text Available Dexamethasone is widely used in preterm infants with severe pulmonary disease. Hypertrophic cardiomyopathy (HCM is a transient side effect observed after multiple doses of dexamethasone. We report a preterm infant with myocardial hypertrophy after a single dose of dexamethasone (0.5 mg/kg used to treat laryngeal edema secondary to prolonged intubation. A benign course was observed without left ventricular outflow tract obstruction and with recovery within 4 weeks. Myocardial effects of dexamethasone may be independent of dose and duration of treatment. The risk/benefit ratio must be carefully considered before using even a single dose of dexamethasone in preterm infants.

    "Late preterm" defines infants born at 34(0/7) through 36(6/7) weeks' gestation, which comprise a majority of preterm births. These infants were treated clinically as "near-term" in the past, but recent studies have implied increased morbidities that differentiate late preterm and term infants. The purpose of this study was to examine the prevalence and clinical complications that could be associated with late preterm birth, as compared to term. This was a retrospective cohort study that reviewed infants born in a medical center in Northern Taiwan during a 2-year period between 2008 and 2009. Maternal obstetrical factors, neonatal demographic distributions, and neonatal complications were compared between full-term and late preterm deliveries. During the study period, there were 7998 live births in the institute, including 6507 term and 1491 preterm infants. Of the latter, there were 914 (61.3%) born after 34 weeks' gestation. The Neonatal Intensive Care Unit (NICU) (including a special care nursery) admission rate was higher in late preterm infants when compared to term (36% vs. 2%), and was 74%, 43%, and 21% in infants born at 34, 35, and 36 weeks' gestation, respectively. Compared with term infants, late-preterm infants had longer hospital stay if admitted to NICU (including special care nursery) (17 days vs. 10 days), and they were associated with increased risk of neonatal morbidities, including respiratory distress syndrome (2.6% vs. 0.02%), respiratory distress of other etiologies (16% vs. 2%), culture-proven sepsis (0.7% vs. 0.2%), hypoglycemia (3% vs. 0.4%), temperature instability (0.4% vs. 0.05%), feeding difficulty (2% vs. 0.4%), and hyperbilirubinemia needing phototherapy (14% vs. 3%). Late-preterm infants also had higher hospital readmission rate (4.4% vs. 2.3%, p<0.001) and neonatal mortality rate (0.3% vs. 0.08%, p=0.03). Late-preterm infants have increased risk of neonatal morbidities associated with organ immaturity. The results of this study

    The majority of children who are born very preterm escape major impairment, yet more subtle cognitive and attention problems are very common in this population. Previous research has linked infant focused attention during exploratory play to later cognition in children born full-term and preterm. Infant focused attention can be indexed by sustained decreases in heart rate (HR). However there are no preterm studies that have jointly examined infant behavioral attention and concurrent HR response during exploratory play in relation to developing cognition. We recruited preterm infants free from neonatal conditions associated with major adverse outcomes, and further excluded infants with developmental delay (Bayley Mental Development Index [MDI < 70]) at 8 months corrected age (CA). During infant exploratory play at 8 months CA, focused attention and concurrent HR response were compared in 83 preterm infants (born 23–32 weeks gestational age [GA]) who escaped major impairment to 46 full-term infants. Focused attention and HR response were then examined in relation to Bayley MDI, after adjusting for neonatal risk. MDI did not differ by group, yet full-term infants displayed higher global focused attention ratings. Among the extremely preterm infants born <29 weeks, fewer days on mechanical ventilation, mean longest focus, and greater HR deceleration during focused attention episodes, accounted for 49% of adjusted variance in predicting concurrent MDI. There were no significant associations for later-born gestational age (29–32 weeks) or full-term infants. Among extremely preterm infants who escape major impairment, our findings suggest unique relationships between focused attention, HR deceleration, and developing cognition. PMID:22487941

    Small-for-gestational-age (SGA) infants have been reported to have a significantly reduced number of nephrons that could be a risk factor for development of hypertension later in life. To evaluate kidney size prospectively in relation to other anthropometric parameters during the first year of life in SGA babies. The babies in the study were 31-36 weeks' gestational age (GA) at birth and were matched with control preterm infants of similar GA, but appropriate for gestational age (AGA). The SGA infants were further classified as symmetrical and asymmetrical according to the anthropometric parameters. The total number of measurements in symmetrical SGA preterm infants was 324, in asymmetrical SGA preterm infants 295, and in AGA infants 536. In symmetrical SGA preterm infants (31-36 weeks' GA) mean kidney length ({+-} SD) of 56{+-}4 mm was significantly different from the controls (58.9{+-}4.6 mm) up to 6 months' chronological age (P < 0.05). In the asymmetrical SGA preterm infants, mean kidney length (45.3{+-}4.0 mm) was significantly different from the controls (48.2{+-}4.4 mm) up to 40 weeks' corrected age. At 1 year chronological age, all preterm infants (symmetrical and asymmetrical SGA and AGA) had similar mean kidney length (61.6{+-}4.6, 62.8{+-}4.3, and 62.3{+-}4.0 mm, respectively). The ratio of kidney length to crown-to-heel length was similar in all preterm groups. Kidney length in preterm SGA infants (symmetrical and asymmetrical) follows closely the other auxological parameters during the first year of life. (orig.)

    The aim of this study was to investigate fathers' emotional experiences of their infant's preterm birth and subsequent stay in neonatal intensive care unit. When a baby is born preterm, there is also the premature interruption of the process of preparation for fatherhood. As a result, the impact on fathers of the preterm birth can bring negative consequences for the development of father-infant relationship. A multi-method approach was used which included ethnographic observation, semi-structured interviews with fathers, a self-report questionnaire and clinical information between September 2015-March 2017. Data were analysed using a mixed-method: a thematic analysis of data from the interviews and quantitative analyses to detect possible clusters of fathers' emotional experiences and associations between clusters and fathers' and/or infants' characteristics. Two clusters were identified. The "fathers-of-preterm-infants" touched their baby as soon as they were given the opportunity and without fear that they would harm their infant. They were struck by their baby's physical appearance. In contrast, the "preterm fathers" preferred not to touch their baby when first given the chance, for fear of breaking/damaging/infecting her/him. They were struck both by the baby's physical appearance and by the technology/equipment around her/him and were afraid that their infant would die. All the "fathers-of-preterm-infants", but only just over half of the "preterm fathers", were actively engaged in their infant's care. Clusters were associated with the infant's gestational age. Fathers of preterm infants should receive personalized support specifically addressed to them and based on the infant's gestational age. © 2018 John Wiley & Sons Ltd.

    The infant mortality rate is a sensitive and commonly used indicator of the socio-economic status of a population. Generally, studies investigating the relationship between infant mortality and socio-economic status have focused on full-term infants in Western populations. This study examined the effects of education level and employment status on full-term and preterm infant mortality in Korea. Data were collected from the National Birth Registration Database and merged with data from the National Death Certification Database. Prospective cohort study. In total, 1,316,184 singleton births registered in Korea's National Birth Registration Database between January 2004 and December 2006 were included in the study. Multivariate logistic regression analysis was performed. Paternal and maternal education levels were inversely related to infant mortality in preterm and full-term infants following multivariate adjusted logistic models. Parental employment status was not associated with infant mortality in full-term infants, but was associated with infant mortality in preterm infants, after adjusting for place of birth, gender, marital status, paternal age, maternal age and parity. Low paternal and maternal education levels were found to be associated with infant mortality in both full-term and preterm infants. Low parental employment status was found to be associated with infant mortality in preterm infants but not in full-term infants. In order to reduce inequalities in infant mortality, public health interventions should focus on providing equal access to education. Copyright © 2013 The Royal Society for Public Health.

    To investigate the usefulness of Multichannel intraluminal impedance-pH (MII-pH) monitoring as compared with conventional pH monitoring for detecting Gastroesophageal reflux (GER) episodes and apnea-related symptom association in preterm infants and neonates. Twenty-three infants (16 preterm and 7 term infants) in hospital, who underwent 24-h MII-pH monitoring, were studied retrospectively. GER indices and apnea-related symptom association were measured by both MII-pH and conventional pH based analysis. Of the total 998 GER episodes assessed by MII-pH monitoring, 407 (40.8%) were acidic and 590 (59.1%) were weakly acidic. A total of 1689 GER episodes were detected by conventional pH based analysis and 270 (16%) were related to retrograde bolus movement. A total of 313 apnea-related symptoms were reported. Five patients had a positive symptom association: 3 by MII-pH, 1 by both MII-pH and conventional pH, 1 only by conventional pH. Addition of MII-pH monitoring to conventional pH monitoring improves the diagnostic yield of symptom association analysis in preterm infants and neonates with apnea-related symptoms. Conventional pH monitoring is still important in the era of impedance measurement.

    A clear relationship exists between undernutrition, poorer growth and poor development in term and preterm infants. However, preterm infants are at greater risk than term infants. Undernutrition is more common and 'programmed' growth rates are almost six times faster. Thus, even short periods of nutritional deprivation may have significant effects. Recent advances have led to an improvement in early growth but very low birthweight infants remain small for gestational age at hospital discharge. Studies suggest that a 'window of opportunity' exists after hospital discharge, in that better growth between discharge and 2-3 months corrected age is paralleled by better development, and poorer growth is associated with poorer development. However, interventions aimed at improving growth and development have yielded varying results. This may partly be related to differences in study design as well as the composition of the nutrient-enriched formulas. Irrespective, one point is concerning, i.e. infant boys appear to be at a developmental disadvantage when fed a term infant formula after discharge. A single study has also suggested that dietary intervention can improve brain growth in term and preterm infants with perinatal brain injury. However, concern has been expressed about rapid 'catch-up' growth in preterm infants and the development of insulin resistance and visceral adiposity. Data from our group do not support the idea of increased or altered adiposity in preterm infants fed a nutrient-enriched formula after hospital discharge. Copyright (c) 2010 S. Karger AG, Basel.

  17. A qualitative study: Mothers of late preterm infants relate their experiences of community-based care.

    Full Text Available In Alberta, the high occurrence of late preterm infants and early hospital discharge of mother-infant dyads has implications for postpartum care in the community. Shortened hospital stay and complexities surrounding the care of biologically and developmentally immature late preterm infants heighten anxiety and fears. Our descriptive phenomenological study explores mothers' experience of caring for their late preterm infants in the community.Eleven mothers were interviewed using a semi-structured interview guide. Interview transcripts were analysed using an interpretive thematic approach.The mothers' hospital experience informed their perspective that being a late preterm infant was not a "big deal," and they tended to treat their infant as normal. "Feeding was really problem," especially the variability in feeding effectiveness, which was not anticipated. Failing to recognize late preterm infants' feeding distress exemplified lack of knowledge of feeding cues and tendencies to either rationalize or minimize feeding concerns. Public health nurses represent a source of informational support for managing neonatal morbidities associated with being late preterm; however, maternal experiences with public health nurses varied. Some nurses used a directive style that overwhelmed certain mothers. Seeing multiple public health nurses and care providers was not always effective, given inconsistent and contradictory guidance to care. These new and changing situations increased maternal anxiety and stress and influenced maternal confidence in care. Fathers, family, and friends were important sources of emotional support.After discharge, mothers report their lack of preparation to meet the special needs of their late preterm infants. Current approaches to community-based care can threaten maternal confidence in care. New models and pathways of care for late preterm infants and their families need to be responsive to the spectrum of feeding issues encountered

    Nutritional management of preterm infants aims to approximate the tissue growth and body composition of a fetus of the same postmenstrual age. The adequacy of the quality of protein supply can influence the rate and the relative quality of weight gain. We investigated the protein balance according to feeding regimen and the association between human milk feeding and fat-free mass content at the term-corrected age in very-low-birth-weight preterm infants. A prospective observational study was conducted. Inclusion criteria were as follows: healthy infants, gestational age ≤32 wk, birth weight milk or formula at discharge. Infants were enrolled at hospital discharge. At enrollment, macronutrient intakes and protein balance were determined. Anthropometric measurements and body composition were also assessed. The nutritional composition of human milk was calculated by infrared spectroscopy. The protein balance was determined according to the nitrogen balance standard method. Body composition was assessed by an air-displacement plethysmography system. At the term-corrected age, anthropometry and body composition assessments were repeated. Seventeen preterm infants fed fortified human milk and 15 preterm infants fed formula were enrolled. At discharge, despite similar macronutrient intakes, infants fed fortified human milk showed a higher nitrogen balance (expressed as mg · kg-1 · d-1) compared with preterm formula-fed infants (mean ± SD: 488.3 ± 75 compared with 409.8 ± 85 mg · kg-1 · d-1, P = 0.009). At term-corrected age, growth was similar in the 2 groups, whereas fortified human milk-fed infants showed a higher percentage of fat-free mass (85.1% ± 2.8% compared with 80.8% ± 3.2%, P = 0.002). Moreover, at multiple linear regression, fat-free mass content was independently associated with being fed human milk (R2 = 0.93, P milk feeding is associated with early fat-free mass deposition in healthy and stable preterm infants.

    Full Text Available Objective: Postnatal tissue accretion in preterm infants differs from those in utero, affecting body composition (BC and lifelong morbidity. Length normalized BC data allows infants with different body lengths to be compared and followed longitudinally. This study aims to analyze BC of preterm and term infants during the first six months of life. Methods: The BC data, measured using dual energy X-ray absorptiometry, of 389 preterm and 132 term infants from four longitudinal studies were combined. Fat-mass/length2 (FMI and fat-free mass/length2 (FFMI for postmenstrual age were calculated after reaching full enteral feeding, at term and two further time points up to six months corrected age. Results: Median FMI (preterm increased from 0.4 kg/m2 at 30 weeks to 2.5, 4.3, and 4.8 kg/m2 compared to 1.7, 4.7, and 6 kg/m2 in term infants at 40, 52, and 64 weeks, respectively. Median FFMI (preterm increased from 8.5 kg/m2 (30 weeks to 11.4 kg/m2 (45 weeks and remained constant thereafter, whereas term FFMI remained constant at 11 kg/m2 throughout the tested time points. Conclusion: The study provides a large dataset of length normalized BC indices. Followed longitudinally, term and preterm infants differ considerably during early infancy in the pattern of change in FMI and FFMI for age.

    A recent trial has demonstrated short-term benefits of a new minimal invasive procedure of surfactant administration in spontaneously breathing preterm infants ≥ 26 weeks (less invasive surfactant administration, LISA). To assess safety as well as short- and long-term outcomes of the LISA procedure in preterm infants between 23-28 weeks of gestation. Preterm infants born between 23+0 and 28+6 weeks gestational age during 2 periods, 18 months before (Period 1, n=44) and 18 months after introduction of LISA (Period 2, n=53), were analyzed for neonatal outcomes. 52% of discharged infants were assessed for neurodevelopmental outcome at corrected age of 3 years. In Period 2, 66% of the preterm infants needing surfactant were treated by the new method of LISA. In this period, fewer patient had to be ventilated during the first 3 days of life (42 vs. 77%, pmechanical ventilation was 2 vs. 3 days (p=0.056). Survival without BPD was 68% in period 1 and 74% in period 2 (p=0.29). In period 2, fewer infants received antibiotics after the third day of life (43 vs. 66%, p=0.04), systemic glucocorticoids were less frequently used (7.5 vs. 23%, p=0.04), and more infants received doxapram (34 vs. 2.3%, pmechanical ventilation in infants >24 weeks. As our study was retrospective the observed trends for better pulmonary and neurocognitive outcomes should be interpreted with caution until results from randomized trials on the LISA procedure are available. © Georg Thieme Verlag KG Stuttgart · New York.

During the first 2 hours, 18 neonates (12.8% exhibited hypoglycemia, and only 2 (2 of 141, 1.4% developed hyperglycemia. From 6 to 24 hours, hypo- and hyperglycemia were observed in 0 and 9 (9 of 141, 6.4% neonates, respectively. Infants small for their GA (SGA were at risk for hypoglycemia both within 24 hours (odds ratio [OR], 2.718; P=0.045 and during days 2 to 7 (OR, 4.454; P=0.006, and hyperglycemia during days 2 to 7 (OR, 3.200; P=0.005. Low 1-minite Apgar score was risk factor for both hypo- and hyperglycemia during days 2 to 7 (OR, 0.756; P=0.035 for hypoglycemia and OR, 0.789; P=0.016 for hyperglycemia. Both hypo- and hyperglycemia within 24 hours were less common in those who started feeding (OR, 0.294; P=0.013 for hypoglycemia and OR, 0.162; P=0.011 for hyperglycemia.ConclusionCareful blood glucose level monitoring is required in preterm infants, especially SGA infants or those with low Apgar score. Early feeding could be beneficial for maintaining euglycemia.

    Spontaneous cries of infants exhibit rich melodic features (i.e., time variation of fundamental frequency [ F 0 ]) even during the neonatal period, and the development of these characteristics might provide an essential base for later expressive prosody in language. However, little is known about the melodic features of spontaneous cries in preterm infants, who have a higher risk of later language-related problems. Thus, the present study investigated how preterm birth influenced melodic features of spontaneous crying at term-equivalent age as well as how these melodic features related to language outcomes at 18 months of corrected age in preterm and term infants. At term, moderate-to-late preterm (MLP) infants showed spontaneous cries with significantly higher F 0 variation and melody complexity than term infants, while there were no significant differences between very preterm (VP) and term infants. Furthermore, larger F 0 variation within cry series at term was significantly related to better language and cognitive outcomes, particularly expressive language skills, at 18 months. On the other hand, no other melodic features at term predicted any developmental outcomes at 18 months. The present results suggest that the additional postnatal vocal experience of MLP preterm infants increased F 0 variation and the complexity of spontaneous cries at term. Additionally, the increases in F 0 variation may partly reflect the development of voluntary vocal control, which, in turn, contributes to expressive language in infancy.

    Full Text Available To describe temporal changes in systolic, diastolic, and mean blood pressure (SBP, DBP, and MBP, respectively in term and preterm infants immediately after birth.Prospective observational two-center study. In term infants SBP, DBP, and MBP were assessed non-invasively every minute for the first 15 minutes, and in preterm infants every minute for the first 15 minutes, as well as at 20, 25, 30, 45, and 60 minutes after birth. Regression analyses were performed by gender and respiratory support in all neonates; and by mode of delivery, cord clamping time, and development of ultrasound-detected brain injury in preterm neonates.Term infants (n = 54 had a mean (SD birth weight of 3298 (442 g and gestational age of 38 (1 weeks, and preterm infants (n = 94 weighed 1340 (672 g and were 30 (3 weeks gestation. Term infants' SBP, DBP and MBP within the first 15 minutes after birth were independent of gender or respiratory support. Linear mixed regression analysis showed that preterm infants, who were female, born vaginally, had delayed cord clamping and did not require positive pressure ventilation nor develop periventricular injury or ventriculomegaly, had significantly higher SBP, DBP, and MBP at some measurement points within the first hour after birth.We present novel reference ranges of BP immediately after birth in a cohort of term and preterm neonates. They may aid in optimization of cardiovascular support during early transition at all gestations.

    Full Text Available Abstract Background Little is known about the factors that predispose to the occurrence and severity of cardio-respiratory symptoms during the placement of a prematurely born infant in a car seat. The impact of gestational age, weight at discharge and infant's pre-existing cardio-respiratory status (in the supine position on cardio-respiratory function during pre-discharge testing in a car seat (semi-upright position has not been investigated. Methods The cardio-respiratory function of 42 preterm neonates with gestational age 24 to 35 weeks and discharge weight 1790 to 2570 grams were monitored for 45 minutes before, during, and after placement in a car seat. The occurrence of periodic breathing, apnea, bradycardia, or decreased oxygen saturation (SaO2 was analyzed. Results Prior to the car seat testing, 15 (35.7% infants displayed one or more abnormalities of cardio-respiratory function. During the car seat testing, 25 (59.6% infants had periodic breathing, 33 (78.2% had oxygen saturation Conclusion Pre-discharge testing of the cardio-respiratory function of preterm infants during placement in a car seat is important for the prevention of cardio-respiratory symptoms during their transportation. However, the high risk for developing cardio-respiratory symptoms will require the consideration of an alternative mode of safe home transportation for preterm infants; especially those with a discharge weight less than 2,000 grams.

    Full Text Available Purpose: To determine the efficacy of the online monitoring tool, WINROP (https://winrop.com/ in detecting sight-threatening type 1 retinopathy of prematurity (ROP in Indian preterm infants. Methods: Birth weight, gestational age, and weekly weight measurements of seventy preterm infants (<32 weeks gestation born between June 2014 and August 2016 were entered into WINROP algorithm. Based on weekly weight gain, WINROP algorithm signaled an alarm to indicate that the infant is at risk for sight-threatening Type 1 ROP. ROP screening was done according to standard guidelines. The negative and positive predictive values were calculated using the sensitivity, specificity, and prevalence of ROP type 1 for the study group. 95% confidence interval (CI was calculated. Results: Of the seventy infants enrolled in the study, 31 (44.28% developed Type 1 ROP. WINROP alarm was signaled in 74.28% (52/70 of all infants and 90.32% (28/31 of infants treated for Type 1 ROP. The specificity was 38.46% (15/39. The positive predictive value was 53.84% (95% CI: 39.59–67.53 and negative predictive value was 83.3% (95% CI: 57.73–95.59. Conclusion: This is the first study from India using a weight gain-based algorithm for prediction of ROP. Overall sensitivity of WINROP algorithm in detecting Type 1 ROP was 90.32%. The overall specificity was 38.46%. Population-specific tweaking of algorithm may improve the result and practical utility for ophthalmologists and neonatologists.

  12. Oxygen supplementation to stabilize preterm infants in the fetal to neonatal transition: no satisfactory answer.

    Directory of Open Access Journals (Sweden)

    2016-04-01

    Full Text Available Fetal life elapses in a relatively low oxygen environment. Immediately after birth with the initiation of breathing the lung expands and oxygen availability to tissue rises by twofold generating a physiologic oxidative stress. However, both lung anatomy and function and the antioxidant defense system do not mature until late in gestation and therefore very preterm infants often need respiratory support and oxygen supplementation in the delivery room to achieve postnatal stabilization. Notably, interventions in the first minutes of life can have long-lasting consequences. Recent trials have aimed to assess what initial inspiratory fraction of oxygen and what oxygen targets during this transitional period are best for extremely preterm infants based on the available nomogram. However, oxygen saturation nomogram informs only of term and late preterm infants but not on extremely preterm infants. Therefore, the solution to this conundrum may still have to wait before a satisfactory answer is available.

    Recurrent apnea is common in preterm infants, particularly at very early gestational ages. These episodes of loss of effective breathing can lead to hypoxemia and bradycardia which may be severe enough to require resuscitation including use of positive pressure ventilation. Theophylline and continuous positive airways pressure (CPAP) are two treatments that have have been used to prevent apnea and its consequences. The main objective was to determine in preterm infants with recurrent apnea, if treatment with CPAP compared with treatment with theophylline leads to a clinically important reduction in apnea or use of mechanical ventilation, without clinically important side effects. Searches were made of the Oxford Database of Perinatal trials, the Cochrane Collaboration Clinical Trials Register, MEDLINE 1966 - July 2001, EMBASE 1980 - July 2001, CINAHL 1982 - July 2001(using text words 'theophylline', 'caffeine', 'CPAP', 'CDAP', 'positive pressure', 'apnea or apnoea' and MeSH term 'infant, premature'), previous reviews including cross references, abstracts, conferences and symposia proceedings, expert informants, mainly in the English language. Abstracts of the Society for Pediatric Research were searched from 1996 - 2001 inclusive. All trials using random or quasi-random allocation to CPAP or theophylline in preterm infants with clinical recurrent apnea/bradycardia were eligible. Data were extracted using standard methods of the Cochrane Collaboration and its Neonatal Review Group, with separate evaluation of trial quality and data extraction by each author and synthesis of data using relative risk. Only one eligible trial was found. The use of mask CPAP is associated with a higher treatment failure rate as measured by less than a 50% reduction in apnea or use of an alternative treatment [RR 2.89 (95% CI 1.12, 7.47); RD 0.42 (95% CI 0.11, 0.74)]. For every 2.4 infants (95% CI 1.4, 9.5) treated with mask CPAP rather than theophylline, there results one treatment

    To evaluate the relationship of weight of preterm infants when first placed into an open crib with days to full oral feedings, growth velocity and length of stay (LOS), and to identify unwarranted variation in incubator weaning after adjusting for severity indices. A retrospective study using the ParadigmHealth neonatal database from 2003 to 2006 reviewed incubator weaning to an open crib in appropriate-for-gestational-age (AGA) infants from 22 to weeks gestation. Primary outcome measurements included days to full oral (PO) feeding, weight gain from open crib to discharge and length of stay. Models were severity adjusted. To understand hospital practice variation, we also used a regression model to estimate the weight at open crib for the top 10 volume hospitals. In all 2908 infants met the inclusion criteria for the study. Their mean weight at open crib was 1850 g. On average every additional 100 g an infant weighed at the open crib was associated with increased time to full PO feeding by 0.8 days, decreased weight gained per day by 1 gram and increased LOS by 0.9 days. For the top 10 volume hospitals, severity variables alone accounted for 9% of the variation in weight at open crib, whereas the hospital in which the baby was treated accounted for an additional 19% of the variation. Even after controlling for severity, significant practice variation exists in weaning to an open crib, leading to potential delays in achieving full-volume oral feeds, decreased growth velocity and prolonged LOS.

    OBJECT Even with improved prenatal and neonatal care, intraventricular hemorrhage (IVH) occurs in approximately 25%-30% of preterm infants, with a subset of these patients developing hydrocephalus. This study was undertaken to describe current trends in hospitalization of preterm infants with posthemorrhagic hydrocephalus (PHH) using the Nationwide Inpatient Sample (NIS) and the Kids' Inpatient Database (KID). METHODS The KID and NIS were combined to generate data for the years 2000-2010. All neonatal discharges with ICD-9-CM codes for preterm birth with IVH alone or with IVH and hydrocephalus were included. RESULTS There were 147,823 preterm neonates with IVH, and 9% of this group developed hydrocephalus during the same admission. Of patients with Grade 3 and 4 IVH, 25% and 28%, respectively, developed hydrocephalus in comparison with 1% and 4% of patients with Grade 1 and 2 IVH, respectively. Thirty-eight percent of patients with PHH had permanent ventricular shunts inserted. Mortality rates were 4%, 10%, 18%, and 40%, respectively, for Grade 1, 2, 3, and 4 IVH during initial hospitalization. Length of stay has been trending upward for both groups of IVH (49 days in 2000, 56 days in 2010) and PHH (59 days in 2000, 70 days in 2010). The average hospital cost per patient (adjusted for inflation) has also increased, from $201,578 to $353,554 (for IVH) and $260,077 to $495,697 (for PHH) over 11 years. CONCLUSIONS The number of neonates admitted with IVH has increased despite a decrease in the number of preterm births. Rates of hydrocephalus and mortality correlated closely with IVH grade. The incidence of hydrocephalus in preterm infants with IVH remained stable between 8% and 10%. Over an 11-year period, there was a progressive increase in hospital cost and length of stay for preterm neonates with IVH and PHH that may be explained by a concurrent increase in the proportion of patients with congenital cardiac anomalies.

    To date, no study has evaluated changes in oral labial angle as preterm infants mature. The main purpose of this study was to document goniometer measurements of the labial angle of the mouth in preterm infants, to assess changes with development, to compare to findings in healthy term infants, and also evaluate oral motor reflexes in these groups. Seventy-eight preterm infants and 45 healthy term infants were recruited for the prospective study. Labial angle was assessed via goniometer, and oral motor reflexes and the volume of milk ingested were evaluated. There was significant difference between term and preterm infants' labial angles (P Goniometer measurements of the oral labial angle may reveal oral motor performance in preterm infants and may be relevant for feeding skills assessment in this group of infants. © The Author(s) 2015.

    Premature infants have a high risk for dysbiosis of the gut microbiome. Mother's own milk (MOM) has been found to favorably alter gut microbiome composition in infants born at term. Evidence about the influence of feeding type on gut microbial colonization of preterm infants is limited. The purpose of this study was to explore the effect of feeding types on gut microbial colonization of preterm infants in the neonatal intensive care unit. Thirty-three stable preterm infants were recruited at birth and followed up for the first 30 days of life. Daily feeding information was used to classify infants into six groups (MOM, human donor milk [HDM], Formula, MOM + HDM, MOM + Formula, and HDM + Formula) during postnatal days 0-10, 11-20, and 21-30. Stool samples were collected daily. DNA extracted from stool was used to sequence the 16S rRNA gene. Exploratory data analysis was conducted with a focus on temporal changes of microbial patterns and diversities among infants from different feeding cohorts. Prediction of gut microbial diversity from feeding type was estimated using linear mixed models. Preterm infants fed MOM (at least 70% of the total diet) had highest abundance of Clostridiales, Lactobacillales, and Bacillales compared to infants in other feeding groups, whereas infants fed primarily HDM or formula had a high abundance of Enterobacteriales compared to infants fed MOM. After controlling for gender, postnatal age, weight, and birth gestational age, the diversity of gut microbiome increased over time and was constantly higher in infants fed MOM relative to infants with other feeding types (p gut microbiome development of preterm infants, including balanced microbial community pattern and increased microbial diversity in early life.

    This study investigated the effect of time post-ingestion on gastric digestion and gastric hormones after feeding preterm infants unfortified and fortified human milk. Human milk and infant gastric samples were collected from 14 preterm (23-32 weeks birth gestational age) mother-infant pairs within 7-98 days postnatal age. Gastric samples were collected one, two and three hours after beginning of feeding. Samples were analysed for pH, proteolysis, general protease activity and the concentrations of pepsin, gastrin and gastrin-releasing peptide (GRP). One-way ANOVA with repeated measures followed by Tukey's multiple comparisons test was used. Gastric pH was significantly decreased after each hour in the preterm infant stomach from one to three hours postprandial. Proteolysis increased significantly from human milk to gastric contents at one, two and three hours postprandial (by 62, 131% and 181%, p milk to the gastric contents at two hours postprandial. GRP was present in human milk, whereas gastrin was produced in the infant stomach. Although preterm infants may digest human milk proteins to a lesser extent than term infants, we demonstrated that the preterm infant stomach actively degrades milk proteins with increasing breakdown over digestion time. ©2018 Foundation Acta Paediatrica.

    Galectin-3 binding protein (Gal3BP) is a glycoprotein isolated in colostrum that may be an immunologically active component with effects on the neonatal immune system. This compound has been found in the blood of term newborn infants, but has not been studied in preterm infants. Compare umbilical cord plasma Gal3BP concentration between preterm and term infants. Observational study of mother-infant pairs consented at UCSD Medical Center comparing umbilical cord plasma Gal3BP concentration in preterm and term infants. Umbilical cord plasma was collected at birth and stored at -80°C before Gal3BP analysis by ELISA. This study was powered to evaluate differences in preterm and term infant Gal3BP concentration. The secondary aim was to determine the effect of maternal and infant clinical factors on Gal3BP concentration. A total of 64 preterm and 30 term umbilical cord plasma samples were analyzed. By univariate analysis, Gal3BP concentration was elevated in the setting of prematurity, maternal diabetes, antenatal steroid exposure, and increasing maternal parity (p Umbilical cord plasma Gal3BP concentration is elevated in prematurity. This may reflect inflammatory states in infant and mother, but further study is warranted.

    Full Text Available Objective: The aim of this pilot study was to determine the effect of music by Mozart on heel prick procedural pain in premature infants.Background: Painful procedures are routinely performed in the setting of neonatal intensive care unit (NICU. Pain may exert short- and long-term deleterious effects on premature babies. Many non-pharmacological interventions have been proven efficacious for blunting neonatal pain.Study design: Randomized, controlled trial.Methods: The study was carried out in the NICU of the “G. Rummo” Hospital in Benevento, Italy. The sample consisted of 42 preterm infants, with no hearing loss or significant cerebral lesions on cranial ultrasound. They were randomized to receive heel lance during a music condition or a no-music control condition. We set strict criteria for selecting and delivering the music. Baseline and postprocedural heart rate and transcutaneous oxygen saturation were manually recorded. The Premature Infant Pain Profile (PIPP score was used to measure the behavioral response to prick. An unpaired t-test was performed for the intergroup comparisons.Results: There were significant differences between groups on heart rate increase, oxygen saturation reduction and PIPP score following the procedure.Conclusions: Listening to Mozart music during heel prick is a simple and inexpensive tool for pain alleviating in preterm stable neonates.

    Background: Apnea of prematurity often occurs during and following caffeine therapy. We hypothesized that number of apnea events would be impacted by adjustments in caffeine therapy. Materials and Methods: An automated algorithm was used in all infants ≤32 weeks gestation admitted to a level IV Neonatal Intensive Care Unit from 2009 to 2014 to analyze chest impedance, electrocardiogram, and oxygen saturation data around the time of serum caffeine levels, caffeine boluses while on maintenance therapy, and caffeine discontinuation. Episodes of central apnea/bradycardia/desaturation (ABDs), and percent time with SpO 2 preterm infants (mean gestational age 27.6 weeks) around the time of 485 serum caffeine levels, 90 caffeine boluses, and 273 episodes of caffeine discontinuation. Higher serum caffeine levels were not associated with fewer ABDs or higher heart rate. For caffeine boluses given due to clinically recognized spells, hypoxemia and algorithm-detected ABDs decreased day 1-2 after the bolus compared to the day before and day of the bolus (mean 4.4 events/day after vs. 6.6 before, p  = 0.004). After caffeine discontinuation, there was no change in hypoxemia and a small increase in ABDs (2 events/day 3-5 days after discontinuation vs. 1 event/day before and >5 days after, p  preterm infants.

    Gut microbiota plays a key role in multiple aspects of human health and disease, particularly in early life. Distortions of the gut microbiota have been found to correlate with fatal diseases in preterm infants, however, developmental patterns of gut microbiome and factors affecting the colonization progress in preterm infants remain unclear. The purpose of this prospective longitudinal study was to explore day-to-day gut microbiome patterns in preterm infants during their first 30 days of life in the neonatal intensive care unit (NICU) and investigate potential factors related to the development of the infant gut microbiome. A total of 378 stool samples were collected daily from 29 stable/healthy preterm infants. DNA extracted from stool was used to sequence the V4 region of the 16S rRNA gene region for community analysis. Operational taxonomic units (OTUs) and α-diversity of the community were determined using QIIME software. Proteobacteria was the most abundant phylum, accounting for 54.3% of the total reads. Result showed shift patterns of increasing Clostridium and Bacteroides, and decreasing Staphylococcus and Haemophilus over time during early life. Alpha-diversity significantly increased daily in preterm infants after birth and linear mixed-effects models showed that postnatal days, feeding types and gender were associated with the α-diversity, pdiversity, whereas females tended to have a higher diversity shortly after birth. Female infants were more likely to have higher abundance of Clostridiates, and lower abundance of Enterobacteriales than males during early life. Infants fed mother's own breastmilk (MBM) had a higher diversity of gut microbiome and significantly higher abundance in Clostridiales and Lactobacillales than infants fed non-MBM. Permanova also showed that bacterial compositions were different between males and females and between MBM and non-MBM feeding types. In conclusion, infant postnatal age, gender and feeding type significantly

    Postnatal growth restriction and failure to thrive is a major issue in preterm, especially extremely low-birth-weight infants. Optimization of enteral nutrition, without increasing the risk of necrotizing enterocolitis (NEC), has thus become a priority for the neonatologist, who often has to face the challenge of interpreting the clinical and prognostic significance of common and aspecific signs of feeding intolerance (FI). The neonatologist often prescribes enteral nutrition as if walking on a tightrope between the purposed attainment of full enteral feeding and the fear of NEC. Despite advances in neonatal intensive care, NEC still remains one of the leading causes of mortality (15-30%) and morbidity in very-low-birth-weight infants. However, the relationship between FI and NEC remains unknown. Feeding intolerance often leads to discontinuation of enteral feeds, delayed attainment of full enteral feeding and prolongation of hospitalization. Strategies aimed at preventing and/or treating episodes of feeding intolerance are diverse and not always supported by scientific evidence.

  7. Clinical Pharmacology of Fentanyl in Preterm Infants. A Review

    Full Text Available Fentanyl is a synthetic opioid that is very important in anesthetic practice because of its relatively short time to peak analgesic effect and the rapid termination of action after small bolus doses. The objective of this survey is to review the clinical pharmacology of fentanyl in preterm infants. The bibliographic search was performed using PubMed and EMBASE databases as search engines. In addition, the books Neofax: A manual of drugs used in neonatal care and Neonatal formulary were consulted. Fentanyl is N-dealkylated by CYP3A4 into the inactive norfentanyl. Fentanyl may be administered as bolus doses or as a continuous infusion. In neonates, there is a remarkable interindividual variability in the kinetic parameters. In neonates, fentanyl half-life ranges from 317 minutes to 1266 minutes and in adults it is 222 minutes. Respiratory depression occurs when fentanyl doses are >5 μg/kg. Chest wall rigidity may occur in neonates and occasionally is associated with laryngospasm. Tolerance to fentanyl may develop after prolonged use of this drug. Significant withdrawal symptoms have been reported in infants treated with continuous infusion for 5 days or longer. Fentanyl is an extremely potent analgesic and is the opioid analgesic most frequently used in the neonatal intensive care unit.

    Infection with respiratory syncytial virus (RSV), which causes lower respiratory tract infections, is the leading cause of hospitalization among children preterm and full-term infants without chronic lung disease or other high-risk conditions. This analysis used Truven Health Market Scan Multi-State Medicaid and Commercial Claims and Encounters databases, which contain a combined 4 million births from 2003 to 2013. Infants with comorbid conditions associated with increased risk for RSV infection were excluded. Infants were classified as preterm (position. Costs of RSV hospitalizations were captured and reported in 2014 USD. Inpatient claims for RSV hospitalizations were evaluated for the presence of codes indicating admission to the intensive care unit (ICU), use of mechanical ventilation (MV) and length of stay. These three measures were used to describe hospital severity. Chronologic age at the time of RSV hospitalization was also captured. Data were summarized and no statistical comparisons were conducted. There were 1 683 188 infants insured through Medicaid and 1 663 832 infants insured through commercial plans born from 1 July 2003 to 30 June 2013. Of those, 10.8 and 8.8% in each database, respectively, were born prematurely. There were 29 967 Medicaid-insured infants and 16 310 commercially insured infants with an RSV hospitalization during their first year of life. Mean first-year RSV hospitalization costs were higher for preterm infants, ranging from $8324 and $10 570 for full-term infants to $15 839 and $19 931 for preterm infants 33-34 wGA, and to $39 354 and $40 813 for preterm infants preterm infants, with longer lengths of stay, a higher proportion of infants admitted to the intensive care unit (ICU) and increased use of MV compared with full-term infants. Mean costs of RSV hospitalizations with a PICU admission ranged from approximately $35 000 to $89 000. In both Medicaid and commercial groups, costs were greater for

    The objective of this study was to compare the prevalence of home care practices in very to moderately preterm (VPT), late preterm (LPT) and term infants born in Massachusetts. Using 2007 to 2010 Massachusetts Pregnancy Risk Assessment Monitoring System data, births were categorized by gestational age (VPT: 23 to 33 weeks; LPT: 34 to 36 weeks; term: 37 to 42 weeks). Home care practices included breastfeeding initiation and continuation, and infant sleep practices (supine sleep position, sleeping in a crib, cosleeping in an adult bed). We developed multivariate models to examine the association of infant sleep practices and breastfeeding with preterm status, controlling for maternal sociodemographic characteristics. Supine sleep position was more prevalent among term infants compared with VPT and LPT infants (77.1%, 71.5%, 64.4%; P=0.02). In the adjusted model, LPT infants were less likely to be placed in supine sleep position compared with term infants (adjusted prevalence ratio=0.86; 95% confidence interval: 0.75 to 0.97). Breastfeeding initiation and continuation did not differ among preterm and term groups. Nearly 16% of VPT and 18% of LPT and term infants were not sleeping in cribs and 14% of LPT and term infants were cosleeping on an adult bed. Compared with term infants, LPT infants were less likely to be placed in supine sleep position after hospital discharge. A significant percent of preterm and term infants were cosleeping on an adult bed. Hospitals may consider improving their safe sleep education, particularly to mothers of LPT infants.

    Objective: To study the effect of family integrated care (FIC) in neonatal intensive care unit (NICU) to the development of preterm infants at 18 months of age. Method: This is a prospective parallel case-control study. Infants in FIC group were preterm infants enrolled in previous FIC study with gestational age (GA) 28-35 weeks. Study period was from July 2015 to July 2016. Subjects were all enrolled from Department of Child Healthcare in the Third Xiangya Hospital of Central South University. Infants in control group were gender, birth weight (BW), BW percentile and days of life (DOL) at follow-up matched (1∶1 ratio) preterm infants who did not enter FIC in NICU. The age at follow-up was 18 months. Study parameters were maternal education year, socioeconomic status (SES) by Graffar method, home observation for measurement of the environment (HOME), mental development index (MDI) and psychomotor development index (PDI) by mental and psychomotor Bayley scales of infant development (BSID). SPSS 20.0 of χ 2 test, t test, Pearson coefficient test and Spearman coefficient test were used for the statistical analysis. Result: Totally 67 infants were enrolled in each of FIC group and control group, with percentage of male gender 52% (35 infants) and 51% (34 infants), representatively. GA of FIC group and control group was (32.4±1.7) and (32.2±1.6) weeks, BW was (1 690±415) and (1 719±412) g. Weight at 18 months follow-up was (10±1) and (10±1) kg, maternal education year was (15±2) and (15±2) years, SES was (42±6) and (41±6) score, HOME was (31±5) and (32±5) score, representatively. There was no significant difference between FIC group and control group in the above parameters, making these 2 groups comparable. The MDI and PDI of FIC group were significantly higher than those of control group ((95±9) vs . (86±9), (87±9) vs . (80±8) score, t =5.506, 4.502, both P =0.000). The MDI and PDI of all groups were positively correlated to GA ( r =0.398 and 0

    To study the evolution of sensory-motor nerves in the upper and lower limbs in neurologically healthy preterm infants and to use sensory-motor studies to compare the rate of maturation in preterm infants at term age and full-term healthy neonates. The study comprised 26 neurologically normal preterm infants born at 23-33 weeks of gestational age, who underwent sensory nerve conduction and motor nerve conduction studies from plantar medial and median nerves and from tibial and ulnar nerves, respectively. We repeated the same neurophysiological studies in 19 of the preterm infants every 2 weeks until postnatal term age. The data from the preterm infants at term was matched with a group of ten full-term babies a few days after birth. The motor nerve conduction velocity of the tibial and ulnar nerves showed progressive increases in values in relation to gestational age, but there was a decrease of values in distal latencies and F wave latencies. Similarly, there was a gradual increase of sensory nerve conduction velocity values of the medial plantar and median nerves and decreases in latencies in relation to gestational age. At term age, the preterm infants showed significantly lower values of conduction velocities and distal latencies than the full-term neonates. These results were probably because the preterm infants had significantly lower weights, total length and, in particular, distal segments of the limbs at term age. The sensory-motor conduction parameters were clearly related to gestational age, but extrauterine life did not affect the maturation of the peripheral nervous system in the very preterm babies who were neurologically healthy.

    It is necessary to thoroughly establish the type of delivery of a late preterm infant in order to prevent an infection in the newborn child. The improvement of diagnosis of intrauterine hypoxia may reduce the number of Caesarean sections. The decision about late preterm delivery should be based on indices of the mother’s state of health. Premature delivery is related to the occurrence of respiratory distress syndrome in a late preterm infant, although the risk is reduced by the application of an antenatal steroid therapy.

    Respiratory distress syndrome (RDS) is the single most important cause of morbidity and mortality in preterm infants (Greenough 1998, Bancalari 1992). Intermittent positive pressure ventilation (IPPV) with surfactant is the standard treatment for the condition. The major difficulty with IPPV is that it is invasive, resulting in airway and lung injury and contributing to the development of chronic lung disease. In spontaneously breathing preterm infants with RDS, to determine if continuous distending airway pressure (CDAP) reduces the need for IPPV and associated morbidity without adverse effects. The standard search strategy of the Neonatal Review group was used. This included searches of the Oxford Database of Perinatal Trials, Cochrane Controlled Trials Register, MEDLINE, previous reviews including cross references, abstracts, conference and symposia proceedings, expert informants, journal hand searching mainly in the English language. All trials using random or quasi-random patient allocation of newborn infants with RDS were eligible. Interventions were continuous distending airway pressure including continuous positive airway pressure (CPAP) by mask, nasal prong, nasopharnygeal tube, or endotracheal tube, or continuous negative pressure (CNDP) via a chamber enclosing the thorax and lower body, compared with standard care. Standard methods of the Cochrane Collaboration and its Neonatal Review Group, including independent assessment of trial quality and extraction of data by each author, were used. CDAP is associated with a lower rate of failed treatment (death or use of assisted ventilation), overall mortality, and mortality in infants with birthweights above 1500 g. The use of CDAP is associated with an increased rate of pneumothorax. In preterm infants with RDS the application of CDAP either as CPAP or CNDP is associated with some benefits, particularly in infants with birthweights over 1500 gms. The extent of this benefit is difficult to assess given the

    Full Text Available Abstract Background High rates of antenatal depression and preterm birth have been reported in Pakistan. Self reported maternal stress and depression have been associated with preterm birth; however findings are inconsistent. Cortisol is a biological marker of stress and depression, and its measurement may assist in understanding the influence of self reported maternal stress and depression on preterm birth. Methods In a prospective cohort study pregnant women between 28 to 30 weeks of gestation from the Aga Khan Hospital for Women and Children completed the A-Z Stress Scale and the Centre for Epidemiology Studies Depression Scale to assess stress and depression respectively, and had a blood cortisol level drawn. Women were followed up after delivery to determine birth outcomes. Correlation coefficients and Wilcoxon rank sum test was used to assess relationship between preterm birth, stress, depression and cortisol. Logistic regression analysis was used to determine the key factors predictive of preterm birth. Results 132 pregnant women participated of whom 125 pregnant women had both questionnaire and cortisol level data and an additional seven had questionnaire data only. Almost 20% of pregnant women (19·7%, 95% CI 13·3-27·5 experienced a high level of stress and nearly twice as many (40·9%, 95% CI 32·4-49·8% experienced depressive symptoms. The median of cortisol level was 27·40 ug/dl (IQR 22·5-34·2. The preterm birth rate was 11·4% (95% CI 6·5-18. There was no relationship between cortisol values and stress scale or depression. There was a significant positive relationship between maternal depression and stress. Preterm birth was associated with higher parity, past delivery of a male infant, and higher levels of paternal education. Insufficient numbers of preterm births were available to warrant the development of a multivariable logistic regression model. Conclusions Preterm birth was associated with higher parity, past delivery

    Infants born preterm and/or with low birth weight may present a clinical condition of organic instability and usually face a long period of hospitalization in the Neonatal Intensive Care Units, being exposed to biopsychosocial risk factors to their development due to decreased spontaneous movement and excessive sensory stimuli. This study assumes that there are relationships between the integration of sensory information of preterm infants, motor development and their subsequent effects. To evaluate the sensory processing and motor development in preterm infants aged 4-6 months and compare performance data with their peers born at term. This was a cross-sectional and comparative study consisting of a group of preterm infants (n=15) and a group of term infants (n=15), assessed using the Test of Sensory Functions in Infants (TSFI) and the Alberta Infant Motor Scale (AIMS). The results showed no significant association between motor performance on the AIMS scale (total score) and sensory processing in the TSFI (total score). However, all infants who scored abnormal in the total TSFI score, subdomain 1, and subdomain 5 presented motor performance at or below the 5th percentile on the AIMS scale. Since all infants who presented definite alteration in tolerating tactile deep pressure and poor postural control are at risk of delayed gross motor development, there may be peculiarities not detected by the tests used that seem to establish some relationship between sensory processing and motor development.

    The aim of this study was to characterize the brain ultrasonographic findings of late-onset circulatory dysfunction (LCD) due to adrenal insufficiency (AI) in preterm infants. Among the 257 preterm infants born at <33 weeks of gestation between December 2009 and February 2014 at our institution, 35 preterm infants were diagnosed with AI. Brain ultrasonographic findings were retrospectively analyzed before and after LCD in 14 preterm infants, after exclusion of the other 21 infants with AI due to the following causes: death (n=2), early AI (n=5), sepsis (n=1), and patent ductus arteriosus (n=13). Fourteen of 257 infants (5.4%) were diagnosed with LCD due to AI. The age at LCD was a median of 18.5 days (range, 9 to 32 days). The last ultrasonographic findings before LCD occurred showed grade 1 periventricular echogenicity (PVE) in all 14 patients and germinal matrix hemorrhage (GMH) with focal cystic change in one patient. Ultrasonographic findings after LCD demonstrated no significant change in grade 1 PVE and no new lesions in eight (57%), grade 1 PVE with newly appearing GMH in three (21%), and increased PVE in three (21%) infants. Five infants (36%) showed new development (n=4) or increased size (n=1) of GMH. Two of three infants (14%) with increased PVE developed cystic periventricular leukomalacia (PVL) and rapid progression to macrocystic encephalomalacia. LCD due to AI may be associated with the late development of GMH, increased PVE after LCD, and cystic PVL with rapid progression to macrocystic encephalomalacia.

    Intraventricular hemorrhage (IVH) or bleed within the brain is a common condition among pre-term infants that occurs in very low birth weight preterm neonates. The prognosis is further worsened by the development of progressive ventricular dilatation, i.e., post-hemorrhagic ventricle dilation (PHVD), which occurs in 10-30% of IVH patients. In practice, predicting PHVD accurately and determining if that specific patient with ventricular dilatation requires the ability to measure accurately ventricular volume. While monitoring of PHVD in infants is typically done by repeated US and not MRI, once the patient has been treated, the follow-up over the lifetime of the patient is done by MRI. While manual segmentation is still seen as a gold standard, it is extremely time consuming, and therefore not feasible in a clinical context, and it also has a large inter- and intra-observer variability. This paper proposes a segmentation algorithm to extract the cerebral ventricles from 3D T1- weighted MR images of pre-term infants with PHVD. The proposed segmentation algorithm makes use of the convex optimization technique combined with the learned priors of image intensities and label probabilistic map, which is built from a multi-atlas registration scheme. The leave-one-out cross validation using 7 PHVD patient T1 weighted MR images showed that the proposed method yielded a mean DSC of 89.7% +/- 4.2%, a MAD of 2.6 +/- 1.1 mm, a MAXD of 17.8 +/- 6.2 mm, and a VD of 11.6% +/- 5.9%, suggesting a good agreement with manual segmentations.

    weeks' gestation, at birth or soon thereafter, and targeted SpO₂ ranges of either 90% or below or above 90% via pulse oximetry, with the intention of maintaining such targets for at least the first two weeks of life. We used the standard methods of Cochrane Neonatal to extract data from the published reports of the included studies. We sought some additional aggregate data from the original investigators in order to align the definitions of two key outcomes. We conducted the meta-analyses with Review Manager 5 software, using the Mantel-Haenszel method for estimates of typical risk ratio (RR) and risk difference (RD) and a fixed-effect model. We assessed the included studies using the Cochrane 'Risk of bias' and GRADE criteria in order to establish the quality of the evidence. We investigated heterogeneity of effects via pre-specified subgroup and sensitivity analyses. Five trials, which together enrolled 4965 infants, were eligible for inclusion. The investigators of these five trials had prospectively planned to combine their data as part of the NeOProM (Neonatal Oxygen Prospective Meta-analysis) Collaboration. We graded the quality of evidence as high for the key outcomes of death, major disability, the composite of death or major disability, and necrotising enterocolitis; and as moderate for blindness and retinopathy of prematurity requiring treatment.When an aligned definition of major disability was used, there was no significant difference in the composite primary outcome of death or major disability in extremely preterm infants when targeting a lower (SpO₂ 85% to 89%) versus a higher (SpO₂ 91% to 95%) oxygen saturation range (typical RR 1.04, 95% confidence interval (CI) 0.98 to 1.10; typical RD 0.02, 95% CI -0.01 to 0.05; 5 trials, 4754 infants) (high-quality evidence). Compared with a higher target range, a lower target range significantly increased the incidence of death at 18 to 24 months corrected age (typical RR 1.16, 95% CI 1.03 to 1.31; typical RD

    Preterm infants provided with sufficient nutrition to achieve intrauterine growth rates have the greatest potential for optimal neurodevelopment. Although human milk is the preferred feeding for preterm infants, unfortified human milk provides insufficient nutrition for the very low-birth-weight infant. Even after fortification with human milk fortifier, human milk often fails to meet the high protein needs of the smallest preterm infants, and additional protein supplementation must be provided. Although substantial evidence exists to support quantitative protein goals for human milk-fed preterm infants, the optimal type of protein for use in human milk fortification remains uncertain. This question was addressed through a PubMed literature search of prospective clinical trials conducted since 1990 in preterm or low-birth-weight infant populations. The following 3 different aspects of protein quality were evaluated: whey-to-casein ratio, hydrolyzed versus intact protein, and bovine milk protein versus human milk protein. Because of a scarcity of current studies conducted with fortified human milk, studies examining protein quality using preterm infant formulas were included to address certain components of the clinical question. Twenty-six studies were included in the review study. No definite advantage was found for any specific whey-to-casein ratio. Protein hydrolyzate products with appropriate formulations can support adequate growth and biochemical indicators of nutrition status and may reduce gastrointestinal transit time, gastroesophageal reflux events, and later incidence of atopic dermatitis in some infants. Plasma amino acid levels similar to those of infants fed exclusive human milk-based diets can be achieved with products composed of a mixture of bovine proteins, peptides, and amino acids formulated to replicate the amino acid composition of human milk. Growth and biochemical indicators of nutrition status are similar for infants fed human milk

    The initial acquisition and early development of the intestinal microbiome during infancy are important to human health across the lifespan. Mode of birth, antibiotic administration, environment of care, and nutrition have all been shown to play a role in the assembly of the intestinal microbiome during early life. For preterm infants, who are disproportionately at risk of inflammatory intestinal disease (i.e., necrotizing enterocolitis), a unique set of clinical factors influence the establishment of the microbiome. The purpose of this study was to establish the influence of nutritional exposures on the intestinal microbiome in a cohort of preterm infants early in life. Principal component analysis of 199 samples from 30 preterm infants (<32 weeks) over the first 60 days following birth showed that the intestinal microbiome was influenced by postnatal time (p < 0.001, R 2  = 0.13), birth weight (p < 0.001, R 2  = 0.08), and nutrition (p < 0.001, R 2  = 0.21). Infants who were fed breast milk had a greater initial bacterial diversity and a more gradual acquisition of diversity compared to infants who were fed infant formula. The microbiome of infants fed breast milk were more similar regardless of birth weight (p = 0.049), in contrast to the microbiome of infants fed infant formula, which clustered differently based on birth weight (p < 0.001). By adjusting for differences in gut maturity, an ordered succession of microbial phylotypes was observed in breast milk-fed infants, which appeared to be disrupted in those fed infant formula. Supplementation with pasteurized donor human milk was partially successful in promoting a microbiome more similar to breast milk-fed infants and moderating rapid increases in bacterial diversity. The preterm infant intestinal microbiome is influenced by postnatal time, birth weight, gestational age, and nutrition. Feeding with breast milk appears to mask the influence of birth weight, suggesting a

    Positioning of preterm infants is a basic task of neonatal nursing care. A variety of outcomes are affected by different body positioning of preterm infants. This review evaluates the clinical evidence of the effects of positioning of preterm infants with regard to physiological outcomes and sleep states. To conduct a systematic review to determine the best available evidence related to the positioning of preterm infants. The specific review questions addressed were: the physiological outcomes affected by different positioning, and the best position for promoting sleep. This review considered all studies that included infants born before 37 weeks of gestational age in any hospital setting. Outcomes included measures for physiologic effects and sleep state. The review primarily considered any randomized clinical trails (RCTs) that explored different positions in preterm infant but also included quasi-experimental designs. The search sought to find published and unpublished studies. The database search included: Pubmed, CINAHL, ProQuest, EMBASE, Science Direct, and Dissertation Abstracts International. Studies were additionally identified from reference lists of all studies retrieved. All studies were checked for methodological quality by two reviewers and data was extracted using tools developed by the Joanna Briggs Institute. The study results were pooled in statistical meta-analysis using Review Manager Software and summarized in narrative form where statistical pooling was not appropriate or possible. Thirty two studies were included in the review. The results of this review support the prone position in preterm infants for improvement of arterial oxygen saturation, improved lung and chest wall synchrony of respiratory improvements, decreased incidence of apnea in infants with a clinical history of apnea, promoted sleep, and decreased gastroesophageal reflux. However, the prone position increased postural abnormalities, orthopaedic abnormalities of the feet, and

    Because of stressors surrounding preterm birth, parents can be expected to have difficulty in early interactions with their preterm infants. Care givers who work with preterm infants and their parents can positively affect the early parental experiences of these mothers and fathers. If care givers are consciously guided by a conceptual model, therapeutic care for distressed parents is more likely to be provided. A logical framework, such as symbolic interactionism, helps care givers to proceed systematically in assessing parental behaviors, in intervening appropriately, and in evaluating both the process and outcome of the care. Selected aspects of the symbolic interaction model are described in this article and applied to the care of parents of preterm infants.

    To assess the well-being of preterm newborns using the Bayley-III scales in a Korean-based population, and to evaluate the perinatal risk factors influencing developmental outcome. Using the Bayley-III scales, we assessed 120 preterm infants who were referred for evaluation of neurodevelopmental performance. We subdivided them into an extremely preterm group (n=18) and a very/moderate to late preterm group (n=102). Bayley-III mean scores and the rate of infants showing a delay were compared for both groups. The relationship between perinatal risk factors and Bayley-III scores was analyzed. The risk factors were considered as very low birth weight, history of neonatal medical problems, and abnormal radiologic findings in brain magnetic resonance images (MRIs). Although no significant differences in mean scores were observed between the extremely preterm group and the very/moderate to late preterm group, the rate of babies showing developmental delay in motor composite scores was significantly higher in the extremely preterm group. The proportions of preterm infants with cognitive, language, and motor delays were 38.3%, 26.7%, and 35.0%, respectively. Very low birth weight was a significant risk factor for low cognitive, language, and motor composite scores. Also, abnormal radiologic findings on brain MRI were significant indicators of lower motor composite scores. Cognitive development was the most frequently delayed domain in preterm infants and motor development was more frequently delayed in the extremely preterm group. The very low birth weight and abnormal radiologic findings in brain MRI were predictive factors for neurodevelopmental outcome.

    To examine levels of parenting stress in mothers of preterm and term infants when the children were 2 years old; to determine the trajectory of stress over three time periods and to examine the association of maternal and neonatal factors and developmental outcomes with parenting stress. It is a prospective longitudinal study to determine parenting stress in mothers of preterm and term infants with outcomes having been previously obtained at 4 and 12 months. At 2 years, 79 preterm mothers (96 babies) and 64 term mothers (77 babies) participated. The mothers completed the Parenting Stress Index-Short Form (PSI-SF), the Depression, Anxiety, Stress Scale (DASS) and the Child Behaviour Checklist (CBCL). The infants had a neurological examination and the Bayley-III scales were administered. The mean total PSI-SF at 2 years was significantly higher for the preterm group compared with the term group of mothers (p=0.007). There was a significant increase in the mean total PSI over time for the preterm mothers (pparenting stress and abnormal scores on the DASS (pparenting stress and maternal demographics, neonatal factors or Bayley-III results. Parenting stress in mothers of preterm infants continues to be high at 2 years having increased over time. Maternal mental health problems and infant behavioural issues contribute to the stress. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Introduction: Preterm infants are unable to regulate their body temperature and there are insufficient research evidences on different kinds of covers for hospitalized preterm infants; therefore, the present study was conducted with the aim of comparing the effects of plastic and blanket covers on the body temperature of preterm infants under radiant warmer. Methods: This randomized cross-over clinical trial was carried out upon 80 infants with the gestational age of 28-30 weeks and birth weight of 800- 1250 gr who were in Neonatal Intensive Care Unit on the second day of their hospitalization. The study lasted for two days. In group 1, the plastic cover was used during the first day of the study while the blankets were used during the second day. Infants' heads were kept out of the cover and coated with a hat. In group 2, the plastic cover was used during the first day of the study while the blanket was used during second day. Digital thermometer was used to measure infants' axillary temperature. The data was analyzed using SPSS ver 13 and MiniTab software. Descriptive statistics, (Mean (SE), 95%CI) and inferential statistics (Repeated measurement and ANCOVA tests) were used. Results: The mean body temperature of the infants in the group covered with the plastic was calculated to be higher and the warmer was set on low temperature. Conclusion: Using plastic cover during the first few days of hospitalization in NICU resulted in regulation of preterm infants' body temperature.

    Full Text Available Abstract Background Randomized controlled trials have shown that treatment of chronically ventilated preterm infants after the first week of life with dexamethasone reduces the incidence of the combined outcome death or bronchopulmonary dysplasia (BPD. However, there are concerns that dexamethasone may increase the risk of adverse neurodevelopmental outcome. Hydrocortisone has been suggested as an alternative therapy. So far no randomized controlled trial has investigated its efficacy when administered after the first week of life to ventilated preterm infants. Methods/Design The SToP-BPD trial is a randomized double blind placebo controlled multicenter study including 400 very low birth weight infants (gestational age Discussion This trial will determine the efficacy and safety of postnatal hydrocortisone administration at a moderately early postnatal onset compared to placebo for the reduction of the combined outcome mortality and BPD at 36 weeks postmenstrual age in ventilator dependent preterm infants.

    This study aimed to investigate the feasibility and efficacy of swaddling to control procedural pain among preterm infants. Swaddling has been recommended for controlling neonatal pain. However, the feasibility for use is uncertain and insufficient evidence is available among preterm infants. A two-arm randomised controlled trial with repeated measures. The study was conducted in a 21-bed neonatal intensive care unit of a regional hospital in Hong Kong. Preterm infants who required heelstick procedure were eligible. Fifty-four preterm infants between 30-37 gestational weeks were randomly assigned to swaddling (n = 27) and control (standard care, n = 27) groups. Pain assessment was performed pre, during, immediate, two, four, six and eight minutes after heelstick procedure using the Premature Infant Pain Profile. The mean Premature Infant Pain Profile scores were significantly reduced in the intervention group compared to the control group during, immediate, two, four, and six minutes after the heelstick procedure. The mean changes of heart rate and oxygen saturation in the intervention group were significantly lower than that of the control group at all measured time points. Notably, the swaddled infants quickly resumed to the baseline level at two minutes whereas the control group reached the stable state at an extended period of six minutes. The findings show that swaddling is feasible and efficacious in controlling pain for heelstick procedure among preterm infants. No adverse effects were observed. This article presents the feasibility and efficacy of swaddling as a non-pharmacological and non-invasive intervention to relieve pain during the heelstick procedures among preterm infants. Swaddling can contribute to control minor procedural pain in neonates as one of the simple, safe, cost effective, humanistic and natural analgesia alternatives. © 2016 John Wiley & Sons Ltd.

    Despite numerous medical advances in the care of at-risk preterm neonates, oral feeding still represents one of the first and most advanced neurological challenges facing this delicate population. Objective, quantitative, and noninvasive assessment tools, as well as neurotherapeutic strategies, are greatly needed in order to improve feeding and developmental outcomes. Pulsed pneumatic orocutaneous stimulation has been shown to improve nonnutritive sucking (NNS) skills in preterm infants who exhibit delayed or disordered nipple feeding behaviors. Separately, the study of the salivary transcriptome in neonates has helped identify biomarkers directly linked to successful neonatal oral feeding behavior. The combination of noninvasive treatment strategies and transcriptomic analysis represents an integrative approach to oral feeding in which rapid technological advances and personalized transcriptomics can safely and noninvasively be brought to the bedside to inform medical care decisions and improve care and outcomes. The study aimed to conduct a multicenter randomized control trial (RCT) to combine molecular and behavioral methods in an experimental conceptualization approach to map the effects of PULSED somatosensory stimulation on salivary gene expression in the context of the acquisition of oral feeding habits in high-risk human neonates. The aims of this study represent the first attempt to combine noninvasive treatment strategies and transcriptomic assessments of high-risk extremely preterm infants (EPI) to (1) improve oral feeding behavior and skills, (2) further our understanding of the gene ontology of biologically diverse pathways related to oral feeding, (3) use gene expression data to personalize neonatal care and individualize treatment strategies and timing interventions, and (4) improve long-term developmental outcomes. A total of 180 extremely preterm infants from three neonatal intensive care units (NICUs) will be randomized to receive either PULSED or

    Spontaneous movements at 2 months of corrected age in preterm infants with intellectual disability (ID) were investigated by assessing individual motor elements separated from movements involving the entire body. Video recordings of 20 preterm infants with ID (16 males, 4 females; median gestational age 26 weeks; median birth weight 810 g) were analyzed and were compared with those of 21 normal preterm infants (8 males, 13 females; median gestational age 30 weeks; median birth weight 1216 g). In the preterm infants with ID at 2 months corrected age, startle response, lateral decumbent position, predominant shoulder rotation, and maintaining hip adduction were more frequently observed and hand sucking, maintaining shoulder abduction, to-and-fro shoulder abduction, to-and-fro elbow flexion, isolated hip adduction, to-and-fro hip abduction, and leg lift were less frequently seen than in the normal preterm infants (Fisher's exact test, ppreterm infants with ID result from persistent immature movements and non-emergence of mature movements.

    Morbidity and mortality in preterm infants is significantly determined by the development of pulmonary complications. We thus investigated the impact of obstructive ventilatory disorders on lung function in very preterm infants with a history of respiratory distress syndrome and/or bronchopulmonary dysplasia using repeated body plethysmographic measurements before and after bronchodilation. Lung function, including effective airway resistance (Raw), specific conductance (SGaw), functional residual capacity (FRCbox), and total respiratory system compliance (Crs, multiple occlusion technique) was assessed in 27 preterm infants pound31 wks gestational age at a median postmenstrual age of 38 wks after mild oral sedation before and after inhalation of nebulized salbutamol (1.25 mg/2.5 mL; PARI JuniorBOY N) using the MasterScreen Baby Body (Jaeger, Hoechberg, Germany). In preterm infants median Raw was initially found to be within the normal range as determined for healthy term newborns, but decreased significantly after administration of salbutamol; SGaw changed accordingly. FRCbox was significantly reduced compared with healthy term newborns (16.6 vs. 19.6 mL/kg, mean) and decreased further after bronchodilation, whereas Crs was not significantly altered. This is the first report quantifying the important impact of obstructive ventilatory disorders on lung function in very preterm infants at term. Besides its important role in preterm lung function consecutive overinflation could furthermore be shown to mask reduction of lung volume in these infants. Thus, body plethysmographic measurements seem to be an important diagnostic tool in preterm infants at term before hospital discharge in order to quantify ventilation disorders and to define therapeutic strategies.

    Positioning is considered vital to the maintenance of good lung ventilation by optimizing oxygen transport and gas exchange in ventilated premature infants. Previous studies suggest that the prone position is advantageous; however, no data exist on regional ventilation distribution for this age group. To investigate the effect of body position on regional ventilation distribution in ventilated and nonventilated preterm infants using electrical impedance tomography. Randomized crossover study design. Neonatal ICU. A total of 24 ventilated preterm infants were compared with six spontaneously breathing preterm infants. Random assignment of the order of the positions supine, prone, and quarter prone. Ventilation distribution was measured with regional impedance amplitudes and global inhomogeneity indices using electrical impedance tomography. In the spontaneously breathing infants, regional impedance amplitudes were increased in the posterior compared with the anterior lung (p < 0.01) and in the right compared with the left lung (p = 0.03). No differences were found in the ventilated infants. Ventilation was more inhomogeneous in the ventilated compared with the healthy infants (p < 0.01). Assessment of temporal regional lung filling showed that the posterior lung filled earlier than the anterior lung in the spontaneously breathing infants (p < 0.02) whereas in the in the ventilated infants the right lung filled before the left lung (p < 0.01). In contrast to previous studies showing that ventilation is distributed to the nondependent lung in infants and children, this study shows that gravity has little effect on regional ventilation distribution.

    BACKGROUND: Human milk banking has been available in many countries for the last three decades. The milk provided from milk banking is predominantly term breast milk, but some milk banks provide preterm breast milk. There are a number of differences between donor term and donor preterm human milk. OBJECTIVES: To determine the effect of banked preterm milk compared with banked term milk regarding growth and developmental outcome in very low birth weight infants (infants weighing less than 1500 g). SEARCH STRATEGY: We used the standard methods of the Cochrane Neonatal Review Group, including a search of the Cochrane Neonatal Group specialized register and the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, January 2010). We searched the computerised bibliographic databases MEDLINE (1966 to February 2010), EMBASE (1988 to February 2010) and Web of Science (1975 to February 2010). We searched reference lists of all selected articles, review articles and the Oxford Database of Perinatal Trials. We also searched abstracts from neonatal and pediatric meetings (PAS electronic version from 2000 to 2009, ESPR hand search from 2000 to 2009). We applied no language restrictions. SELECTION CRITERIA: Randomised and quasi-randomised trials comparing banked donor preterm milk with banked donor term milk regarding growth and developmental outcomes in very low birth weight infants DATA COLLECTION AND ANALYSIS: We planned to perform assessment of methodology regarding blinding of randomisation, intervention and outcome measurements as well as completeness of follow-up. We planned to evaluate treatment effect using a fixed-effect model using relative risk (RR), relative risk reduction, risk difference (RD) and number needed to treat (NNT) for categorical data and using mean, standard deviation and weighted mean difference (WMD) for continuous data. We planned an evaluation of heterogeneity. MAIN RESULTS: No studies met the inclusion criteria. AUTHORS

    Full Text Available Background: Inguinal hernia is a common disease in preterm infants necessitating surgical repair. Despite the increased risk of postoperative apnea in preterm infants, the procedure was conventionally performed under general anesthesia. Recently, regional anesthesia approaches, including spinal and caudal blocks have been proposed as safe and efficient alternative anesthesia methods in this group of patients. The current study evaluates awake caudal and spinal blocks in preterm infants undergoing inguinal hernia repair. Materials and Methods: In a randomized clinical trial, 66 neonates and infants (weight <5 kg undergoing inguinal hernia repair were recruited in Tabriz Teaching Children Hospital during a 12-month period. They were randomly divided into two equal groups; receiving either caudal block by 1 ml/kg of 0.25% bupivacaine plus 20 μg adrenaline (group C or spinal block by 1 mg/kg of 0.5% bupivacaine plus 20 μg adrenaline (group S. Vital signs and pain scores were documented during operation and thereafter up to 24 h after operation. Results: Decrease in heart rate and systolic blood pressure was significantly higher in group C throughout the study period (P < 0.05. The mean recovery time was significantly higher in group S (27.3 ± 5.5 min vs. 21.8 ± 9.3 min; P = 0.03. Postoperative need for analgesia was significantly more frequent in group S (75.8% vs. 36.4%; P = 0.001. Failure in anesthesia was significantly higher in group S (24.4% vs. 6.1%; P = 0.04. Conclusion: More appropriate success rate, duration of recovery and postoperative need of analgesics could contribute to caudal block being a superior anesthesia technique compared to spinal anesthesia in awaked preterm infants undergoing inguinal hernia repair.

    Late preterm infants (34-36 weeks' gestation) remain a population at risk for apnea of prematurity (AOP). As infants affected by respiratory distress syndrome (RDS) have immature lungs, they might also have immature control of breathing. Our hypothesis is that an association exists between RDS and AOP in late preterm infants. The primary objective of this study was to assess the association between RDS and AOP in late preterm infants. The secondary objective was to evaluate if an association exists between apparent RDS severity and AOP. This retrospective observational study was realized in a tertiary care center between January 2009 and December 2011. Data from late preterm infants who presented an uncomplicated perinatal evolution, excepted for RDS, were reviewed. Information related to AOP and RDS was collected using the medical record. Odds ratios were calculated using a binary logistic regression adjusted for gestational age and sex. Among the 982 included infants, 85 (8.7%) had an RDS diagnosis, 281 (28.6%) had AOP diagnosis, and 107 (10.9%) were treated with caffeine for AOP. There was a significant association between AOP treated with caffeine and RDS for all infants (OR = 3.3, 95% CI: 2.0-5.7). There was no association between AOP and RDS in 34 weeks infants [AOR: 1.6 (95% CI: 0.7-3.8)], but an association remains for 35 [AOR: 5.7 (95% CI: 2.5-13.4)] and 36 [OR = 7.8 (95% CI: 3.2-19.4)] weeks infants. No association was found between apparent RDS severity and AOP, regarding mean oxygen administration duration or complications associated with RDS. The association between RDS and AOP in late preterm infants reflects that patients affected by RDS are not only presenting lung immaturity but also respiratory control immaturity. Special consideration should be given before discontinuing monitoring after RDS resolution in those patients.

    Full Text Available Tanya Tripathi,1 Stacey C Dusing2,3 1Rehabilitation and Movement Science Program, Department of Physical Therapy, 2Department of Physical Therapy, 3Department of Pediatrics, Children's Hospital of Richmond, Virginia Commonwealth University, Richmond, VA, USA Purpose: Late preterm (LPT births constitute a large proportion of the preterm births in the USA. Over the last few decades, there has been an increase in research focusing on the neurodevelopment of infants born LPT. The purpose of this research was to systematically review the long-term neurodevelopmental outcomes in LPT infants. Materials and methods: We identified studies by using PubMed, ERIC, CINAHL, and PsycINFO databases. The references of included papers were reviewed for additional papers that met the inclusion criteria. Included papers compared motor, cognitive, language development, or academic performance outcomes between individuals born LPT and a term control group assessed between 12 months and 18 years of age. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards for systematic reviews were utilized including a two-step, two-investigator review process. Results: Of the 4,720 studies found in the initial search, 20 studies met the inclusion criteria. Approximately 75% of the 16 studies that assessed cognitive outcomes reported cognitive delay in the LPT group when compared to their full-term counterparts. More than 50% of the seven studies that assessed motor outcomes suggested a delay in motor development in the LPT group in comparison to full-term. Fewer papers assessed academic performance and language in children born LPT; however, the majority identified borderline differences when LPT infants were compared to those born full-term. Conclusion: Evidence suggests that infants born LPT are at an increased risk of neurodevelopmental delay between 1 and 18 years of life when compared to those born at term. The delay is most evident in the cognitive

    Full Text Available Background: Preterm neonates comprise the most heavily transfused group of patients, and about 85% of extremely low birth weight newborns receive a transfusion by the end of their hospital stay. The aim of this study was to assess the possible metabolic effects of RBC transfusion on preterm infants, especially during the first 2 weeks of life, and its relation to blood volume. Materials and Methods: This study was conducted on 40 preterm neonates with gestational age of less than or equal to 34 weeks. They received RBCs transfusion during first 2 weeks of life. Venous blood samples of infants were collected 2 to 4 hours before and 1 hour after the end of transfusion to evaluate hemoglobin (Hb level, hematocrit, acid-base, electrolytes, and glucose status. Then, infants were classified into two main groups: those who received RBCs volume less than or 20 ml/kg and those who received RBCs volume more than 20 ml/kg. Results: Infants received a mean volume of 20.38 ± 3.2 ml/kg RBCs (range, 10.9 - 26.6 ml/kg at a median age of 9.8 ± 3.6 days. After transfusion, a significant increase of mean Hb (P<0.001, mean Hct (P<0.001, pH (P<0.001, pO 2 (P<0.05, and a significant decrease of the pCO2 (41.46 ± 8.8torr vs 35.4 ± 9.34 torr; P<0.001 were observed. In addition, there was a significant increase of serum K + (P<0.001, and a significant decrease of Ca +2 (P<0.001. A positive correlation was found between the K + intake and the changes of kalemia (r = 0.99; P = 0.00. Furthermore, we observed an inverse correlation between the patients′ calcium intake and the changes of calcemia (r = -0.35; P = 0.02. On comparing the changes in clinical and biochemical variables between two groups after transfusion, we observed a significant increase in mean Hb and Hct associated with a significant decrease in mean serum Ca +2 (P<0.001 in the group receiving the larger blood volume. Conclusion: RBC transfusion was effective in improving anemia, oxygenation, increasing

    The purpose of the present study was to determine the effect of feeding nutrient-enriched preterm formula to preterm infants until 6 months' corrected age (CA) on growth and development in the first 18 months of life. Very low-birthweight preterm infants were fed preterm formula until term (40 weeks CA). Infants were then assigned to one of three groups and were fed term formula until 6 months' CA (group 1, n= 29); preterm formula to 3 months' CA and then term formula to 6 months' CA (group 2, n= 30); or preterm formula until 6 months' CA (group 3, n= 31). Anthropometry was performed at term, 3, 6, 9, 12, 15, and at s18 months' CA. Mental and psychomotor development were assessed using the Bayley Scales of Infant Development II at 18 months' CA. Although body weight, length, head circumference and z score for CA at term in group 3 were significantly lower than those of groups 1 and 2, growth rates of these parameters were significantly higher in group 3 up to 18 months CA', as compared to groups 1 and 2. The mental developmental index and psychomotor developmental index of the Bayley test were not significantly different between the three groups. Very low-birthweight preterm infants fed nutrient-enriched preterm formula until 6 months' CA demonstrated significantly improved growth rates for bodyweight, length and head circumference, and comparable mental and psychomotor development throughout the first 18 months of life. © 2011 The Authors.

    Poor breastfeeding outcomes among late preterm infants (LPIs) have been attributed to inadequate breast milk transfer stemming from physiological immaturities. However, breastfeeding is more than a biological phenomenon, and it is unclear how mothers of LPIs manage other factors that may also impact the breastfeeding course. Using grounded theory methods and incorporating serial postpartum interviews with several novel data collection techniques, we examined breastfeeding establishment over a 6–8 week period among 10 late preterm mother-infant dyads recruited from a maternity hospital in Pittsburgh, Pennsylvania, USA. We found that breastfeeding in the LPI population was a fluctuating, cascade-like progression of trial and error, influenced by a host of contextual factors and events and culminating with breastfeeding continuation (with or without future caveats for duration or exclusivity of breastfeeding) or cessation. The trajectory was explained by the basic psychosocial process Weighing Worth against Uncertain Work, which encompassed the tension between breastfeeding motivation, the intensity of breastfeeding work, and ambiguity surrounding infant behavior and feeding cues. Several sub-processes were also identified: Playing the Game; Letting Him be the Judge vs. Accommodating Both of Us; and Questioning Worth vs. Holding out Hope. If valid, our theoretical model indicates a need for earlier, more extensive, and more qualified breastfeeding support for mothers of late preterm infants that emphasizes the connection between prematurity and observed feeding behaviors.

    Full Text Available Abstract Background Late onset sepsis is a frequent complication of prematurity associated with increased mortality and morbidity. The commensal bacteria of the gastrointestinal tract play a key role in the development of healthy immune responses. Healthy term infants acquire these commensal organisms rapidly after birth. However, colonisation in preterm infants is adversely affected by delivery mode, antibiotic treatment and the intensive care environment. Altered microbiota composition may lead to increased colonisation with pathogenic bacteria, poor immune development and susceptibility to sepsis in the preterm infant. Probiotics are live microorganisms, which when administered in adequate amounts confer health benefits on the host. Amongst numerous bacteriocidal and nutritional roles, they may also favourably modulate host immune responses in local and remote tissues. Meta-analyses of probiotic supplementation in preterm infants report a reduction in mortality and necrotising enterocolitis. Studies with sepsis as an outcome have reported mixed results to date. Allergic diseases are increasing in incidence in "westernised" countries. There is evidence that probiotics may reduce the incidence of these diseases by altering the intestinal microbiota to influence immune function. Methods/Design This is a multi-centre, randomised, double blinded, placebo controlled trial investigating supplementing preterm infants born at Bifidobacterium infantis, Streptococcus thermophilus and Bifidobacterium lactis. A total of 1,100 subjects are being recruited in Australia and New Zealand. Infants commence the allocated intervention from soon after the start of feeds until discharge home or term corrected age. The primary outcome is the incidence of at least one episode of definite (blood culture positive late onset sepsis before 40 weeks corrected age or discharge home. Secondary outcomes include: Necrotising enterocolitis, mortality, antibiotic usage, time to

    2012-09-01

    To evaluate infant thermal balance and the physical environment in extremely preterm infants during skin-to-skin care (SSC). Measurements were performed in 26 extremely preterm infants (gestational age 22-26 weeks; postnatal age, 2-9 days) during pretest (in incubator), test (during SSC), and posttest (in incubator) periods. Infants' skin temperature and body temperature, ambient temperature, and relative humidity were measured. Evaporimetry was used to determine transepidermal water loss, and insensible water loss through the skin was calculated. The infants maintained a normal body temperature during SSC. Transfer to and from SSC was associated with a drop in skin temperature, which increased during SSC. Ambient humidity and temperature were lower during SSC than during incubator care. Insensible water loss through the skin was higher during SSC. SSC can be safely used in extremely preterm infants. SSC can be initiated during the first week of life and is feasible in infants requiring neonatal intensive care, including ventilator treatment. During SSC, the conduction of heat from parent to infant is sufficiently high to compensate for the increase in evaporative and convective heat loss. The increased water loss through the skin during SSC is small and should not affect the infant's fluid balance. Copyright © 2012 Mosby, Inc. All rights reserved.

    To describe the long-term outcome of very preterm infants receiving prolonged sedation and/or analgesia and examine the relationship between prolonged sedation and/or analgesia and this long-term outcome. A prospective population-based study (Etude EPIdémiologique sur les Petits Ages GEstationnels [EPIPAGE]). To reduce bias, the propensity score method was used. Nine regions of France. The study population included very preterm infants of fewer than 33 weeks' gestational age, born in 1997, who received mechanical ventilation and/or surgery. Main Exposure Prolonged exposure to sedative and/or analgesic drugs in the neonatal period, defined as exposure of more than 7 days to sedative and/or opioid drugs. Presence of moderate or severe disability at 5 years of age. The analysis concerns 1572 premature infants who received mechanical ventilation for whom information about exposure to prolonged sedation and/or analgesia in the neonatal period was available. A total of 115 were exposed and 1457 were not exposed. There was no significant difference between the number of patients lost to follow-up from the group of very preterm infants who were exposed to prolonged sedation and/or analgesia and the group who were not. Exposed very preterm infants had severe or moderate disability at 5 years (41/97; 42%) more often than those who were not exposed (324/1248; 26%). After adjustment for gestational age and propensity score, this association was no longer statistically significant (adjusted relative risk, 1.0; 95% confidence interval, 0.8-1.2). Prolonged sedation and/or analgesia is not associated with a poor 5-year neurological outcome after adjustment for the propensity score.

    Full Text Available Introduction: Although the survival rate of infants born preterm has increased, the prevalence of developmental problems and motor disorders among this population of infants remains the same. This study investigated the effect of physical activity programs in and out of water on motor performance and neuromuscular development of infants born preterm and had induced immobility by mechanical ventilation.Methods: This study was carried out in Al-Zahra hospital, Tabriz. 76 premature infants were randomly assigned into four groups. One group received daily passive range of motion to all extremities based on the Moyer-Mileur protocol. Hydrotherapy group received exercises for shoulders and pelvic area in water every other day. A combination group received physical activity programs in and out of water on alternating days. Infants in a containment group were held in a fetal position. Duration of study was two weeks ‘from 32 through 33 weeks post menstrual age (PMA. Motor outcomes were measured by the Test of Infant Motor Performance. Neuromuscular developmental was assessed by New Ballard scale and leg recoil and Ankle dorsiflexion items from Dubowitz scale. Data were analyzed using SPSS version 13.Results: TIMP and neuromuscular scores improved in all groups. Motor performance did not differ between groups at 34 weeks PMA. Postural tone of leg recoil was significantly higher in physical activity groups post intervention.Conclusion: Physical activities and containment didn’t have different effects on motor performance in infants born preterm. Leg recoil of neuromuscular development items was affected by physical activity programs.

    Previous studies have shown that preterm children are at a higher risk for cognitive and language delays than full-term children. Most of these studies have concentrated on the effects of prematurity during the preschool or school years, while the effect of preterm birth on the early development of language, much of which occurs during the first year of life, remains very little explored. This article focuses on this crucial period and reviews the studies that have explored early phonological and lexical development in preterm infants. The results of these studies show uneven proficiency in different language subdomains in preterm infants. This raises the possibility that different constraints apply to the acquisition of different linguistic subcomponents in this population, in part as a result of a complex interaction between maturation, experience, and language subdomains.

    Purpose: To assess the brain maturation of preterm infants using diffusion tensor imaging (DTI) and enhanced T2 star weighted angiography (ESWAN). Materials and methods: Conventional magnetic resonance imaging (MRI), DTI and ESWAN were performed in 60 preterm infants and 21 term controls. 60 preterm infants were subgrouped to two groups according to the age at imaging: before and at term-equivalent age (TEA). Fractional anisotropy (FA), apparent diffusion coefficient (ADC) map from DTI, T{sub 2}* and R{sub 2}* maps from ESWAN were post-processed at an off-line workstation. The values of FA, ADC, T{sub 2}* and R{sub 2}* from the posterior limb of internal capsule (PLIC), frontal white matter (FWM), occipital white matter (OWM) and lentiform nuclei (LN) were determined. These parameters were compared between preterm and term infants. Correlations of DTI and ESWAN parameters with the gestational age, postmenstrual age and postnatal age were analyzed. Results: ADCs of FWM, OWM and LN, and T{sub 2}* values of the PLIC and LN were higher in the preterm infants at TEA compared with the term controls. The correlations were existed between the postmenstrual age and the values of FA, ADC, T{sub 2}*, R{sub 2}* from the PLIC, values of ADC, T{sub 2}*, R{sub 2}* from the LN, T{sub 2}* value from the OWM. The correlations were also found between the postnatal age and the values of FA, ADC, T{sub 2}* from the PLIC, and T{sub 2}* value from the LN. Conclusion: The maturity of preterm brain around TEA was different from that of term controls and appeared to be independent of the prematurity at birth. T{sub 2}* was one of valuable indices to evaluate brain maturation in preterm infants.

    To assess whether preterm infants are at increased risk of pertussis infection and whether this increased following introduction of a maternal pertussis vaccination in England, while examining characteristics of infants associated with more severe disease. Infants aged pertussis diagnosis code were extracted from Hospital Episode Statistics (HES) data. HES data were reconciled with existing surveillance systems to capture maternal vaccination status where available. Cases were compared preimplementation and postimplementation of the maternal programme with respect to demography, preterm or full-term birth and coinfection. Survival analysis was undertaken to assess the impact of variables on duration of hospital stay. The proportion of hospitalised preterm infants (138/1309, 10.6%) was higher than population estimates (7.4%), increasing from 9.8% (83/847) to 12.1% (56/462) following implementation of the maternal programme. Longer duration of hospital stay was associated with prematurity, younger age, additional respiratory illnesses and mothers unvaccinated in pregnancy. Of 13 deaths, 5 were preterm (38.5%) and 11 (84.6%) were female. A larger proportion of full-term infants' (49/188, 26.1%) mothers had been vaccinated in pregnancy than preterm infants (7/49, 14.3%), with 14.3% of mothers of full-term cases vaccinated after 35 weeks. Preterm infants are over-represented in hospitalised pertussis cases and have less benefit from the maternal pertussis vaccination programme in England due to reduced opportunity for maternal vaccination. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Objective To determine the genetic contribution to risk for respiratory distress syndrome (RDS) among moderately preterm, late preterm, and term infants (estimated gestational age ≥32 weeks) of African and European-descent. Study Design We reviewed clinical records for 524 consecutive twin pairs ≥32 weeks gestation. We identified pairs in which at least 1 twin had RDS (n=225) and compared the concordance of RDS between monozygotic (MZ) and dizygotic twins (DZ). Using mixed effects logistic regression, we identified covariates that increased disease risk. We performed additive genetic, common environmental, and residual effects modeling to estimate genetic variance and used the ratio of genetic variance to total variance to estimate genetic contribution to RDS disease risk. Results Monozygotic twins were more concordant for RDS than dizygotic twins (p=0.0040). Estimated gestational age, European-descent, male sex, delivery by cesarean, and five minute Apgar score each independently increased risk for RDS. After adjusting for these covariates, genetic effects accounted for 58% (p=0.0002) of the RDS disease risk variance for all twin pairs. Conclusions In addition to environmental factors, genetic factors may contribute to RDS risk among moderately preterm, late preterm, and term infants. Discovery of risk alleles may be important for prediction and management of RDS risk. PMID:26935785

This was a retrospective, observational, case-control study conducted in Italy, based on administrative database analysis. The aim of this study was to evaluate differences in health care costs of preterm infants with and without early hospitalization for bronchiolitis. Patients and methods: Preterm infants born in the period between January 1, 2009 and December 31, 2010 and hospitalized for bronchiolitis in the first year of life were selected from the ARNO Observatory database and observed for the first 4 years of life. These preterm infants were compared (paired 1–3 with preterm infants who were not hospitalized for bronchiolitis in the first year of life and with similar characteristics. Only direct health care costs reimbursed by the Italian National Health Service were considered for this study (drugs, hospitalizations, and diagnostic/therapeutic procedures. Results: Of 40,823 newborns in the accrual period, 863 were preterm with no evidence of prophylaxis, and 22 preterm infants were hospitalized for bronchiolitis (cases and paired with 62 controls. Overall, cases had 74% higher average cost per infant in the first 4 years of life than controls (18,624€ versus 10,189€, respectively. The major cost drivers were hospitalizations, accounting for >90% in both the populations. The increase in total yearly health care cost between cases and controls remained substantial even in the fourth year of life for all cost items.

    Full breastfeeding is the ultimate aim for preterm infants to ensure they receive the full benefits of human milk however, preterm infants face a number of challenges associated with their immaturity and associated morbidities. In order to facilitate oral feeding, it is essential to have a sound knowledge of the sucking dynamics of the breastfed infant. The aim of this study was to measure and describe the sucking dynamics of the preterm breastfeeding infant. A prospective cross sectional observational study was carried out at King Edward Memorial Hospital, Perth. 38 mothers and their preterm infants (birth gestation age: 23.6-33.3 weeks; corrected gestation age 32.7 to 39.9 weeks) were recruited. Intra-oral vacuum levels, tongue movement and milk intake for a single breastfeed was measured. Statistical analysis employed linear regression and linear mixed effects models. Synchronised ultrasound and intra-oral vacuum measurements show that the preterm infant generates vacuum by lowering their tongue in a parallel fashion, without distortion of the nipple/nipple shield. Baseline (B), mean (M) and (P) peak suck burst vacuums weakened over the course of a feed (B: p = 0.015; M: p = 0.018; P: p = 0.044) and mean and peak vacuums were weaker if the mother fed with a nipple shield (M: p = 0.012; P: p = 0.021). Infant milk intakes were higher when infants sucked for longer (p = 0.002), sucked for a greater proportion of the feed (p = 0.002), or had a greater sucking efficiency (p preterm infants generated intra-oral vacuum in the same manner as term infants. Nipple shields were associated with weaker intra-oral vacuums. However, vacuum strengths were not associated with milk intake rather time spent actively sucking was related to milk volumes. Further research is required to elucidate factors that influence preterm infant milk intake during breastfeeding.

    The immature fragile skin of preterm infants represents an inadequate protective barrier. The emollient and anti-infective properties of coconut oil make it a potentially beneficial topical agent for this population. Our aim was to evaluate feasibility, safety, and the effects of topical coconut oil on skin condition in very preterm infants. An open-label randomised controlled trial in preterm infants coconut oil (5 mL/kg) twice daily for 21 days, starting within 24 h of birth. The neonatal skin condition was the primary outcome, and was assessed using the Neonatal Skin Condition Score (NSCS) on days 1, 7, 14, and 21. The number of coconut oil applications was recorded to assess clinical feasibility and all enrolled infants were monitored for adverse effects of topical coconut application, such as skin irritation. A total of 72 infants born coconut oil was feasible and without adverse effects. The NSCS was maintained in the coconut oil group throughout the intervention period, but deteriorated from a median (IQR) of 3 (3-4) on day 1 to 4 (4-4) on day 21 in the control group (p = 0.01). There were no differences in common neonatal outcomes, including sepsis, necrotising enterocolitis, retinopathy of prematurity, chronic lung disease, and mortality. Topical coconut oil maintained a better skin condition in very preterm infants without adverse effects. This simple, safe, and affordable intervention warrants further investigation. © 2017 S.

    Full Text Available The nonnutritive suck (NNS is an observable and accessible motor behavior which is often used to make inference about brain development and pre-feeding skill in preterm and term infants. The purpose of this study was to model NNS burst compression pressure dynamics in the frequency and time domain among two groups of preterm infants, including those with respiratory distress syndrome (RDS, N=15 and 17 healthy controls. Digitized samples of NNS compression pressure waveforms recorded at a 1-week interval were collected 15 minutes prior to a scheduled feed. Regression analysis and ANOVA revealed that healthy preterm infants produced longer NNS bursts and the mean burst initiation cycle frequencies were higher when compared to the RDS group. Moreover, the initial 5 cycles of the NNS burst manifest a frequency modulated (FM segment which is a significant feature of the suck central pattern generator (sCPG, and differentially expressed in healthy and RDS infants. The NNS burst structure revealed significantly lower spatiotemporal index values for control versus RDS preterm infants during FM, and provides additional information on the microstructure of the sCPG which may be used to gauge the developmental status and progression of oromotor control systems among these fragile infants.

    The rate of weight gain in preterm infants who are exposed to music seems to improve. A potential mechanism could be increased metabolic efficiency; therefore, we conducted this study to test the hypothesis that music by Mozart reduces resting energy expenditure (REE) in growing healthy preterm infants. DESIGN. A prospective, randomized clinical trial with crossover was conducted in 20 healthy, appropriate-weight-for-gestational-age, gavage-fed preterm infants. Infants were randomly assigned to be exposed to a 30-minute period of Mozart music or no music on 2 consecutive days. Metabolic measurements were performed by indirect calorimetry. REE was similar during the first 10-minute period of both randomization groups. During the next 10-minute period, infants who were exposed to music had a significantly lower REE than when not exposed to music (P = .028). This was also true during the third 10-minute period (P = .03). Thus, on average, the effect size of music on REE is a reduction of approximately 10% to 13% from baseline, an effect obtained within 10 to 30 minutes. Exposure to Mozart music significantly lowers REE in healthy preterm infants. We speculate that this effect of music on REE might explain, in part, the improved weight gain that results from this "Mozart effect."

    Apnea of prematurity (AOP) is nearly universal among very preterm infants, but neither the apnea burden nor its clinical associations have been systematically studied in a large consecutive cohort. We analyzed continuous bedside monitor chest impedance and electrocardiographic waveforms and oxygen saturation data collected on all neonatal intensive care unit (NICU) patients 50 infant-years of data). Apneas, with bradycardia and desaturation (ABDs), defined as central apnea ≥10 s associated with both bradycardia hemorrhage (IVH) after accounting for GA. In the day before diagnosis of late-onset septicemia and necrotizing enterocolitis, ABD events were increased in some infants. Many infants continued to experience short ABD events in the week prior to discharge home. Frequency of apnea events is a function of GA and PMA in infants born preterm, and increased apnea is associated with acute but not with chronic pathologic conditions.

    Full Text Available BACKGROUND AND AIM: Evidence-based knowledge of how to guide the mothers of preterm infants in breastfeeding establishment is contradictive or sparse. The aim was to investigate the associations between pre-specified clinical practices for facilitating breastfeeding, and exclusive breastfeeding at discharge as well as adequate duration thereof. METHODS: A prospective survey based on questionnaires was conducted with a Danish national cohort, comprised of 1,221 mothers and their 1,488 preterm infants with a gestational age of 24-36 weeks. Adjusted for covariates, the pre-specified clinical practices were analysed by multiple logistic regression analyses. RESULTS: At discharge 68% of the preterm infants were exclusively breastfed and 17% partially. Test-weighing the infant, and minimizing the use of a pacifier, showed a protective effect to exclusive breastfeeding at discharge (OR 0.6 (95% CI 0.4-0.8 and 0.4 (95% CI 0.3-0.6, respectively. The use of nipple shields (OR 2.3 (95% CI 1.6-3.2 and the initiation of breast milk expression later than 48 hours postpartum (OR 4.9 (95% CI 1.9-12.6 were associated with failure of exclusive breastfeeding at discharge. The clinical practices associated with an inadequate breastfeeding duration were the initiation of breast milk expression at 12-24 hours (OR 1.6 (95% CI 1.0-2.4 and 24-48 hours (OR 1.8 (95% CI 1.0-3.1 vs. before six hours postpartum, and the use of nipple shields (OR 1.4 (95% CI 1.1-1.9. CONCLUSION: Early initiation of breast milk pumping before 12 hours postpartum may increase breastfeeding rates, and it seems that the use of nipple shields should be restricted. The use of test-weighing and minimizing the use of a pacifier may promote the establishment of exclusive breastfeeding, but more research is needed regarding adequate support to the mother when test-weighing is ceased, as more of these mothers ceased exclusive breastfeeding at an early stage after discharge.

    This study was done to compare breast feeding rates and factors influencing feeding practice between late preterm (34 ≤ GA neonatal intensive care units (NICU) of 4 university hospitals in D city. Data were collected from July 2009 to June 2010 from 324 medical records in the NICU. Breast-feeding at home was checked either by telephone survey or questioning during hospital visits. Rate of breast feeding for late preterm infants was significantly lower than for preterm infants. There was no significant difference in breast-feeding at home. We found differences in factors influencing breast feeding between the two groups. Factors influencing feeding for late preterm infants were type of delivery, mothers' occupation, feeding type during hospitalization, time elapse from hospital discharge, total admission days, infant's body weight at first feeding and length of NPO (nothing by mouth). Factors influencing feeding for preterm infants were birth order, maternal disease and obstetric complications, and one-minute Apgar score. Results of the study show low rates of breast-feeding for late preterm infants indicating a need for breast-feeding education for mothers of these infants.

    Full Text Available Technology advances and scientific studies in Neonatal Intensive Care Units (NICU have contributed significantly to reduce mortality and morbidity of at-risk newborns (NB. However, they are more likely to present neurological and/or developmental psychomotor delay with neurological and sensory alterations. Therefore, proposals for neonatal intervention were developed with the aim of protecting the baby and offering appropriate incentives to minimize the effects of hospital intervention. To this end, programs of protective measures such as the Kangaroo Mother Care (KMC were developed. Given the relevance of the issue described, this systematic review critically appraises articles from the national and international literature, published in recent years (from 2000 to 2011, that describe whether the KMC can be a protective factor for the development of writing in premature infants. The textual search was conducted using the Virtual Health Library (VHL, a website that covers publications worldwide, allowing access to articles from health science, including LILACS, IBECS, MEDLINE, Cochrane Library and SciELO, as database. The findings revealed that infants who participated in the KMC program showed improvements in their development and that factors such as low-birth-weight prematurity and learning disorders have close relationship with the onset of motor impairments and changes in psychomotor development. The findings showed no articles describing the KMC as a protective factor for the incidence of dysgraphia. Thus, we emphasize the importance of conducting further studies on these topics.

    Localized persistent pulmonary interstitial emphysema has rarely been reported in preterm infants in the absence of utilization of mechanical ventilation or continuous positive airway pressure. The relative rarity of this condition might preclude rendering of the correct diagnosis, making patients susceptible to unnecessary surgery and increased morbidity and mortality associated with such intervention. We present a preterm infant who developed respiratory distress and radiographic findings of pulmonary interstitial emphysema on the first day after birth, prior to receiving continuous positive airway pressure or mechanical ventilation. It is important for radiologists to consider localized persistent pulmonary interstitial emphysema in the differential diagnosis of cystic lung lesions in preterm infants, even in the absence of mechanical ventilation. In cases where there is uncertainty, CT imaging can be useful in making the correct diagnosis. (orig.)

    Full Text Available The use of natriuretic peptides in the neonatal population is emerging. B-type Natriuretic Peptide (BNP and N-terminal-Pro-BNP (NTpBNP are used in the adult population to assess myocardial function and volume loading. Their role in prognosis following cardiac surgery has also been identified. In preterm infants NTpBNP is becoming increasingly recognised as a potential screening tool for patent ductus arteriosus (PDA, and a marker for myocardial performance. In addition, NTpBNP may provide prognostic information in preterm infants and term infants with congenital diaphragmatic hernia (CDH. In this paper, the role of NTpBNP in the preterm population will be discussed.

    Widespread white matter (WM) pathology in preterm children has been proposed. The purpose of this study was to investigate maturational differences of WM between preterm infants with thinning of the corpus callosum and full-term infants. A total of 18 preterm children and 18 full-term children were divided into three subgroups according to the corrected age at the time of diffusion tensor imaging scanning. Tract-based spatial statistics was used for assessing differences in fractional anisotropy (FA) between preterm and full-term children, and between each age-related subgroup in preterm and in full-term children. In the preterm group, FA values of overall WM showed an increase with age. This trend indicates that WM maturation is a gradual occurrence during a child's first 2 years. In the full-term group, most WM structures had reached maturation at around 1 year of age; however, centrum semiovale level showed sustained maturation during the first 2 years. Results of our study demonstrate radiologic maturational differences of WM and provide evidence of the need for therapeutic intervention within 2 years of birth to prevent specific functional impairment and to improve clinical outcome in preterm children.

    The goal was to assess the feasibility of earlier weaning from the incubator for preterm infants. This was a prospective, randomized study with preterm infants with birth weights of neonatal subintensive ward. Findings for 47 infants who were transferred from an incubator to an open crib at >1600 g (early transition group) were compared with those for 47 infants who were transferred from an incubator to an open crib at >1800 g (standard transition [ST] group). The primary outcome of the study was length of stay. Secondary outcomes were the number of infants returned to an incubator, the growth velocity in an open crib and during the first week at home, the proportions of breastfeeding at discharge and during the first week at home, and the hospital readmission rate. The length of stay was significantly shorter in the early transition group than in the standard transition group (23.5 vs 33 days; P=.0002). No infants required transfer back to the incubator. Only 1 infant in the standard transition group was readmitted to the hospital during the first week after discharge. Growth velocities and individual amounts of breastfeeding were similar between the 2 groups. In this study, weaning of moderately preterm infants from incubators to open cribs at 1600 g was safe and resulted in earlier discharge.

    The birth of a preterm infant has a long-term impact on both parents. Mothers report more stress and poor adjustment compared with fathers. Influencing factors, such as family situation and health status of the child, can support or weaken the coping ability of the parents. Studies on experiences of fathers are sparse. The aim of this research was to study how mothers and fathers of preterm infants describe their experiences of parenthood during the infant's first 18 months of life. Seven consecutively selected sets of parents of preterm infants born at alienation, responsibility, confidence and familiarity. Within the syntheses, similarities in how mothers and fathers described their parental roles involved concern for the child, insecurity, adjustment and relationship with the child. Regarding differences, mothers experienced having more responsibility and control of the care and a need to be confirmed as a mother, while fathers described confidence in leaving the care to the staff and wanted to find a balance between work and family life. Important turning points in parenthood experiences often occurred when the infant could be removed from the incubator, discharged from the ward, and when the infant looked normal compared to full-term infants. The structure of the phenomenon of parenthood was formed by the integration of the syntheses of alienation, responsibility, confidence and familiarity. The structure seems to be based on the parents' expectations of the parental role, the infant's health condition and the health care environment. These interacting factors are influenced by cultural beliefs.

    AIM—To determine changes in brain haemodynamics produced by dexamethasone; to evaluate the pathophysiological conditions involved in the effect of dexamethasone.
METHODS—A prospective study was made of 12 ventilated preterm infants who received dexamethasone (0.25 mg/kg/12 hours) for ongoing chronic lung disease or extubation failure. Cerebral blood flow (CBF), absolute cerebral blood volume (CBV), and cerebral blood volume changes (ΔCBV) were estimated by near infrared spectroscopy, before and 10, 30, 60, 120, 180 and 240 minutes after the first, third, and fifth doses of dexamethasone. All patients were monitored continuously using pulse oximetry, transcutaneous blood gases, and blood pressure.
RESULTS—There were significant short term changes in ΔCBV on each day of the study; ΔCBV increased significantly at 240 minutes compared with values before the first dose, and from 120 minutes onward during the third and fifth doses. However, mean CBV values averaged over 240 minutes after the first, third, and fifth doses did not vary. Mean CBF values averaged over 240 minutes increased progressively up to the fifth dose (significant differences between the first and fifth dose). The short term changes in CBF consisted of a significant increase 60 minutes after dexamethasone administration compared with the before and 10 minute values in every study. Blood pressure was significantly higher in the third and fifth doses than in the first dose. Blood pressure showed no short term changes. There was no correlation between CBF and blood pressure changes. TcPCO2 (transcutaneous PCO2) decreased significantly throughout the study period, with the average mean value in the fifth dose significantly lower than in the first dose. Nevertheless, no short term changes in TcPCO2 were observed.
CONCLUSIONS—Postnatal systemic dexamethasone administration produced significant changes in cerebral haemodynamics that seemed to be related to both a direct effect on regional

    Pathomorphology in the preterm infant represents an interaction of morphological organ immaturity and neonatal management with their respective sequelae. Pathomorphological examples include the modification in the morphology of hyaline membrane disease and bronchopulmonary dysplasia as a consequence of modern neonatal therapy. Hemorrhagic and ischemic/hypoxic lesions of the central nervous system may occur in age- and agent-related distributional patterns, with subependymal hemorrhage and periventricular leukomalacia representing the most important examples. The most common intestinal finding, namely, necrotizing enterocolitis, typically shows segmental alterations, the morphology of which largely depends on the dominating causative agent. Hepatic cholestasis and fatty change are mostly consequences of parenteral nutrition or hypoxic/ischemic stress. Hepatic necrosis can be associated with the latter, but may also indicate disseminated intravascular coagulation. Vascular pathomorphology is represented by thromembolic lesions, in most instances corresponding to sequelae of neonatal management. (orig.) [German] Die Pathomorphologie des Fruehgeborenen kann als Wechselspiel von Morphologie der Organunreife und Therapie sowie deren Folgen angesehen werden. Beispiele zur Pathomorphologie: Beispiele inkludieren den Wandel im morphologischen Bild des sog.

Haemorrhagische und ischaemisch-hypoxische Laesionen des ZNS weisen oft alters- und ursachenabhaengige Verteilungsmuster auf, wobei subependymaere Blutungen und periventrikulaere Leukomalazie mit ihren Spaetfolgen die wichtigsten Beispiele darstellen. Das haeufigste intestinale Krankheitsbild, die nekrotisierende Enterokolitis, praesentiert sich mit segmentalen Laesionen, deren Morphologie in Abhaengigkeit vom dominierenden ausloesenden Faktor

    Background For the premature infant, extrauterine life is a pathological condition which greatly amplifies the challenges to the brain in establishing functional oromotor behaviors. The extent to which suck can be entrained using a synthetically patterned orocutaneous input to promote its development in preterm infants who manifest chronic lung disease is unknown. Objective To evaluate the effects of a frequency-modulated orocutaneous pulse train delivered through a pneumatically-charged pacifier capable of enhancing non-nutritive suck (NNS) activity in tube-fed premature infants. Methods A randomized trial to evaluate the efficacy of pneumatic orocutaneous stimulation 3x/day on NNS development and length of stay (LOS) in the NICU among 160 newborn infants distributed among 3 subpopulations, including healthy preterm infants (HI), respiratory distress syndrome (RDS), and chronic lung disease (CLD). Study infants received a regimen of orocutaneous pulse trains through a PULSED pressurized silicone pacifier or a SHAM control (blind pacifier) during gavage feeds for up to 10 days. Results Mixed modeling, adjusted for the infant’s gender, gestational age, postmenstrual age, and birth weight, was used to handle interdependency among repeated measures within subjects. A significant main effect for stimulation mode (SHAM pacifier vs PULSED orosensory) was found among preterm infants for NNS Bursts/minute (p=.003), NNS events/minute (p=.033), and for Total Oral Compressions/minute [NNS+nonNNS] (p=.016). Pairwise comparison of adjusted means using Bonferroni adjustment indicated RDS and CLD infants showed the most significant gains on these NNS performance indices. CLD infants in the treatment group showed significantly shorter LOS by an average of 2.5 days. Conclusion Frequency-modulated PULSED orocutaneous pulse train stimuli delivered through a silicone pacifier are effective in facilitating NNS burst development in tube-fed RDS and CLD preterm infants, with an added

    Early nCPAP seems to prevent ventilator-induced lung injury in humans, although the pathophysiological mechanisms underlying this beneficial effect have not been clarified yet. To evaluate plasma levels IL-1β, IL-6, IL-8, IL-10, and TNF-α immediately before the start of nCPAP and 2 hours later in preterm infants. Prospective cohort including preterm infants with 28 to 35 weeks gestational age with moderate respiratory distress requiring nCPAP. Extreme preemies, newborns with malformations, congenital infections, sepsis, surfactant treatment, and receiving ventilatory support in the delivery room were excluded. Blood samples were collected right before and 2 hours after the start of nCPAP. 23 preterm infants (birth weight 1851±403 grams; GA 32.3±1.7 weeks) were treated with nCPAP. IL-1β, IL-10, TNF-α levels were similar, IL-8 levels were reduced in 18/23 preterm infants and a significant decrease in IL-6 levels was observed after 2 hours of nCPAP. All newborns whose mothers received antenatal steroids had lower cytokine levels at the onset of nCPAP than those whose mothers didn't receive it; this effect was not sustained after 2 hours of nCPAP. Early use nCPAP is not associated with rising of plasma pro-inflammatory cytokines and it seems to be a less harmful respiratory strategy for preterm with moderate respiratory distress.

    Recent guidelines for preterm neonates recommend early initiation of parenteral nutrition (PN) with high protein and relatively high caloric intake. This review considers whether these changes could influence homeostasis in very preterm infants during the first few postnatal weeks. This systematic review of relevant literature from searches of PubMed and recent guidelines was reviewed by investigators from several perinatal centers in France. New recommendations for PN could be associated with metabolic acidosis via the increase in the amino acid ion gap, hyperchloremic acidosis, and ammonia acidosis. The introduction of high-intake amino acids soon after birth could induce hypophosphatemia and hypercalcemia, simulating a "repeat feeding-like syndrome" and could be prevented by the early intake of phosphorus, especially in preterm infants born after fetal growth restriction. Early high-dose amino acid infusions are relatively well tolerated in the preterm infant with regard to renal function. Additional studies, however, are warranted to determine markers of protein intolerance and to specify the optimal composition and amount of amino acid solutions. Optimal PN following new guidelines in very preterm infants, despite their demonstrated benefits on growth, may induce adverse effects on ionic homeostasis. Clinicians should implement appropriate monitoring to prevent and/or correct them.

  8. The general movement assessment helps us to identify preterm infants at risk for cognitive dysfunction

    Full Text Available Apart from motor and behavioral dysfunctions, deficits in cognitive skills are among the well-documented sequelae of preterm birth. However, early identification of infants at risk for poor cognition is still a challenge, as no clear association between pathological findings based on neuroimaging scans and cognitive functions have been detected as yet. The Prechtl General Movement Assessment (GMA has shown its merits for the evaluation of the integrity of the young nervous system. It is a reliable tool for identifying infants at risk for neuromotor deficits. Recent studies on preterm infants demonstrate that abnormal general movements also reflect impairments of brain areas involved in cognitive development. The aim of this systematic review was to discuss studies that included (i the Prechtl GMA applied in preterm infants, and (ii cognitive outcome measures in six data bases. Seven studies met the inclusion criteria and yielded the following results: (a children born preterm with consistently abnormal general movements up to 8 weeks after term had lower intelligence quotients at school age than children with an early normalization of general movements; (b from 3 to 5 months after term, several qualitative and quantitative aspects of the concurrent motor repertoire, including postural patterns, were predictive of intelligence at 7 to 10 years of age. These findings in 428 individuals born preterm suggest that normal general movements along with a normal motor repertoire during the first months after term are markers for normal cognitive development until at least age 10.

    Periventricular white matter (WM) echodensities, frequently seen in preterm infants, can be associated with suboptimal neurodevelopment. Major WM injury is well detected on cranial ultrasound (cUS). cUS seems less sensitive for diffuse or more subtle WM injury. Our aim was to assess the value of cUS and magnetic resonance imaging (MRI) for evaluating WM changes and the predictive value of cUS and/or MRI findings for neurodevelopmental outcome in very preterm infants with normal to severely abnormal WM on sequential high-quality cUS. Very preterm infants (<32 weeks) who had sequential cUS and one MRI within the first three postnatal months were included. Periventricular WM on cUS and MRI was compared and correlated with neurodevelopmental outcome at 2 years corrected age. Forty preterm infants were studied; outcome data were available in 32. WM changes on sequential cUS were predictive of WM changes on MRI. Severely abnormal WM on cUS/MRI was predictive of adverse outcome, and normal-mildly abnormal WM of favorable outcome. Moderately abnormal WM on cUS/MRI was associated with variable outcome. Additional MRI slightly increased the predictive value of cUS in severe WM changes. Sequential cUS in preterm infants is reliable for detecting WM changes and predicting favorable and severely abnormal outcome. Conventional and diffusion-weighted MRI sequences before term equivalent age in very preterm infants, suggested on cUS to have mild to moderately abnormal WM, do not seem to be warranted. (orig.)

    Full Text Available Background: In the past several years, randomized controlled trials (RCTs have indicated that inhaled nitric oxide (iNO can potentially lower for both the incidence of bronchopulmonary dysplasia (BPD and mortality in affected infants. Other research has, however, disagreed with these findings. Materials and Methods: We performed an updated meta analysis of all relevant RCTs to assess the benefits of iNO in preterm infants by searching PubMed, EMBASE, Cochrane databases, Wanfang, VIP, and CNKI databases for English and Chinese references. Results: Ultimately, 22 RCTs were incorporated. (1 Risk of BPD was significantly lower in preterm infants supplemented with iNO (relative risk [RR] = 0.88; P = 0.0007. There are no differences concerning pulmonary hemorrhage (PH (RR = 0.94; P = 0.72. (2 Incidences of necrotizing enterocolitis (NEC, retinopathy of prematurity (ROP, and severe intracranial hemorrhage (ICH were compared. No significant difference was discovered concerning these risks (RR = 1.21, P = 0.08; RR = 1.01, P = 0.89; and RR = 0.99, P = 0.86. (3 In addition, no significant differences were found between experimental and control groups with respect to morality. (RR = 1.00, P = 0.98. Conclusion: Our meta analysis has shown a beneficial effect in BPD and morality. In addition, our meta analysis suggests that iNO therapy does not increase the risk of common complications, such as NEC and ROP, and that it may also have no adverse effect on bleeding tendency diseases (severe ICH and PH.

    Full Text Available Home care, continuous follow-up, and endless post discharge support play vital role in preventing the emergence of mental and physical disabilities and death among preterm infants. Providing necessary care and support for such infants requires huge financial and human resources and exposes heavy costs on hygiene and health system. Internet and information sharing applications, particularly Web 2.0, and social media present innovative techniques to provide a convenient channel to exchange necessary information between infants, parents, and caregivers. Despite the increasingly expanding use of social media in health and medicine, such devices have rarely been applied in more specialized fields, such as the hygiene and health of preterm infants. Thus, the present study aims at investigating studies published on the experiences of parent in regard with the integration of social media in the improvement of preterm infant treatment, determining the function of social media in taking better care of preterm infants, and presenting suggestions for further practical researches in this area of knowledge. This review study was conducted in 2016. To conduct the study, published articles in the years 2005 to 2016, in English with an emphasis on Social media and Preterm infants were studied. Search was done in databases including Pubmed, Science Direct, Google Scholar, Proquest. The collected data were analyzed. The role of social media in three areas of preterm infants care, sharing the knowledge of clinical professionals, and sharing parenting experiences was clarified. Social media provide the necessary background for the distribution of the knowledge of medical experts; it also creates the opportunities of exchanging ideas, sharing parenting experiences, and expanding the knowledge of experts and educated individuals in addition to providing a stress free environment.

    Full Text Available Gut microbiota plays a key role in multiple aspects of human health and disease, particularly in early life. Distortions of the gut microbiota have been found to correlate with fatal diseases in preterm infants, however, developmental patterns of gut microbiome and factors affecting the colonization progress in preterm infants remain unclear. The purpose of this prospective longitudinal study was to explore day-to-day gut microbiome patterns in preterm infants during their first 30 days of life in the neonatal intensive care unit (NICU and investigate potential factors related to the development of the infant gut microbiome. A total of 378 stool samples were collected daily from 29 stable/healthy preterm infants. DNA extracted from stool was used to sequence the V4 region of the 16S rRNA gene region for community analysis. Operational taxonomic units (OTUs and α-diversity of the community were determined using QIIME software. Proteobacteria was the most abundant phylum, accounting for 54.3% of the total reads. Result showed shift patterns of increasing Clostridium and Bacteroides, and decreasing Staphylococcus and Haemophilus over time during early life. Alpha-diversity significantly increased daily in preterm infants after birth and linear mixed-effects models showed that postnatal days, feeding types and gender were associated with the α-diversity, p< 0.05-0.01. Male infants were found to begin with a low α-diversity, whereas females tended to have a higher diversity shortly after birth. Female infants were more likely to have higher abundance of Clostridiates, and lower abundance of Enterobacteriales than males during early life. Infants fed mother's own breastmilk (MBM had a higher diversity of gut microbiome and significantly higher abundance in Clostridiales and Lactobacillales than infants fed non-MBM. Permanova also showed that bacterial compositions were different between males and females and between MBM and non-MBM feeding types

    Preterm neonates are highly sensitive to systemic infections in early life but little is known about systemic immune development following preterm birth. We hypothesized that preterm neonates have immature systemic immunity with distinct developmental trajectory for the first several weeks of life, relative to those born at near-term or term. Using pigs as a model, we characterized blood leukocyte subsets, antimicrobial activities and TLR-mediated cytokine production during the first weeks after preterm birth. Relative to near-term and term pigs, newborn preterm pigs had low blood leukocyte counts, poor neutrophil phagocytic rate, and limited cytokine responses to TLR1/2/5/7/9 and NOD1/2 agonists. The preterm systemic responses remained immature during the first postnatal week, but thereafter showed increased blood leukocyte numbers, NK cell proportion, neutrophil phagocytic rate and TLR2-mediated IL-6 and TNF-α production. These immune parameters remained different between preterm and near-term pigs at 2–3 weeks, even when adjusted for post-conceptional age. Our data suggest that systemic immunity follows a distinct developmental trajectory following preterm birth that may be influenced by postnatal age, complications of prematurity and environmental factors. Consequently, the immediate postnatal period may represent a window of opportunity to improve innate immunity in preterm neonates by medical, antimicrobial or dietary interventions. PMID:27830761

    Full Text Available BACKGROUND: Severe unconjugated hyperbilirubinemia may cause deafness. In the Netherlands, 25% lower total serum bilirubin (TSB treatment thresholds were recently implemented for preterm infants. OBJECTIVE: To determine the rate of hearing loss in jaundiced preterms treated at high or at low TSB thresholds. DESIGN/METHODS: In this retrospective study conducted at two neonatal intensive care units in the Netherlands, we included preterms (gestational age 35 dB. RESULTS: There were 479 patients in the high and 144 in the low threshold group. Both groups had similar gestational ages (29.5 weeks and birth weights (1300 g. Mean and mean peak TSB levels were significantly lower after the implementation of the novel thresholds: 152 ± 43 µmol/L and 212 ± 52 µmol/L versus 131 ± 37 µmol/L and 188 ± 46 µmol/L for the high versus low thresholds, respectively (P<0.001. The incidence of hearing loss was 2.7% (13/479 in the high and 0.7% (1/144 in the low TSB threshold group (NNT = 50, 95% CI, 25-3302. CONCLUSIONS: Implementation of lower treatment thresholds resulted in reduced mean and peak TSB levels. The incidence of hearing impairment in preterms with a gestational age <32 weeks treated at low TSB thresholds was substantially lower compared to preterms treated at high TSB thresholds. Further research with larger sample sizes and power is needed to determine if this effect is statistically significant.

    Full Text Available Background: Considering the susceptibility of preterm infants to disturbances of vital signs, this study was conducted to investigate the effects of using plastic covers on regulation of vital signs in preterm neonates.Methods: This randomized, cross-over, clinical trial was carried out on 80 preterm infants admitted to neonatal intensive care unit (NICU of Taleghani Hospital, Tabriz, Iran. The study was conducted in two days (on the second and third days of the infants’ life. In group 1, plastic cover was used during the first day followed by the use of blanket on the second day, while the order was reversed in group 2. Digital thermometer was used to measure the infants’ axillary temperature. Heart rate and oxygen saturation were measured through monitoring. To analyze the data, descriptive (Mean and SE, 95%CI and inferential statistics (repeated measurement and ANCOVA tests were used in SPSS version 13 and MiniTab software.Results: Fourteen infants who were covered with blanket were found to suffer from hypothermia, while no infant with a plastic cover encountered this problem. The percentage of arterial blood oxygen saturation in the group with plastic covers was higher, and as a result, the infants received less oxygen supplements. However, no statistically significant differences were observed in heart rate between the groups.Conclusion: Use of plastic cover during NICU stay prevented hypothermia in premature infants, with the arterial blood oxygen saturation being within the normal limits. Yet, it did not seem to have a significant effect on other vital signs.

    The objective of this review is to synthesize the best available evidence related to the effectiveness of music as pain relieving method among preterm infants during painful procedures in the neonatal intensive care unit.Review questions are: Among preterm infants in the neonatal intensive care unit, is music effective in reducing BACKGROUND: Preterm infants (i.e. babies born at or before 37 gestational weeks) compose a patient group of the most vulnerable to pain. Infants treated in a neonatal intensive care unit (NICU) are exposed to a variety of painful procedures (e.g. heel prick, iv cannula insertion, endotracheal suctioning) and to environmental stress (e.g. noise, light). Simons et al., for example, described an average 14 +/- 4 painful procedures during the first 2 weeks of life within a period of 24 hours among 151 neonates. Many studies have shown that repeated and sustained pain can have direct and long-term consequences on the neurological and behavior-oriented development of the neonates during the rapid development phase of the central nervous system. Pain can cause detectable physiological, behavioral and hormonal changes and contribute to the altered development of the pain system during later childhood and adolescence. Instead, live music such as singing is excellent type of music when it is steady, constant, quiet, soothing and directed to the infants. Graven emphasizes that recorded sound should not replace human voice exposure in the NICU; therefore, health care providers should provide ample opportunity for the infant to hear parent's voices live, such as singing or humming, in interactions between the parent and the infant at the bedside.The AmericanAcademy of Pediatrics Committee on Environmental Health has recommended safe levels of sound, and these recommendations have been updated by an expert team of practitioners. Recommendations specify that continuous sound should not exceed an hourly equivalent sound level of 50 A-weighted decibels (d

    Conventional mechanical ventilation (CMV) of neonates has been used as a treatment of respiratory failure for over 30 years. While CMV facilitates gas exchange, it may simultaneously damage the lung. Positive end expiratory pressure (PEEP) has received less attention than other ventilation parameters when considering this balance of benefit and possible harm. While an appropriate level of PEEP may exert substantial benefits in ventilation, both inappropriately low or high levels may lead to harm. An appropriate level of PEEP for neonates may also be best achieved by an individualized approach. 1. To compare the effects of different levels of PEEP in preterm newborn infants requiring CMV for respiratory distress syndrome (RDS).2. To compare the effects of different levels of PEEP in preterm infants requiring CMV for bronchopulmonary dysplasia (BPD).3. To compare the effects of different methods for individualizing PEEP to an optimal level in preterm newborn infants requiring CMV for RDS. The search was performed in accordance with the standard search strategy for the Cochrane Neonatal Review Group. The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), Ovid MEDLINE, EMBASE, study references and experts were utilized for study identification. All randomized and quasi-randomized controlled trials studying preterm infants (less than 37 weeks gestational age) requiring CMV with endotracheal intubation and undergoing randomization to either different PEEP levels (RDS or BPD) or two or more alternative methods for individualizing PEEP levels (RDS only) were included. Cross-over trials were included but we limited the findings to those in the first cross-over period. Data collection and analysis were performed in accordance with the recommendations of the Cochrane Neonatal Review Group. An initial evaluation identified 10 eligible articles. Ultimately, a single study met our inclusion criteria. The study addressed the effects of different

    The purpose of this review was to examine the topics covered in current programs of nursing research on the care of the preterm infant and to determine the extent to which this research is informed by developmental science. A researcher was considered to have a current program of research if he or she had at least five publications published since 1990 and was the first author on at least three of them. The infants in a study could be any age from birth throughout childhood; studies focusing on parenting, nursing, or other populations of infants were not included. Seventeen nurse researchers had current programs of research in this area. These programs had four themes. Those of Becker, Evans, Pridham, Shiao, and Zahr focused on infant responses to the neonatal intensive care unit (NICU) environment and treatments. Franck, Johnston, and Stevens focused on pain management. Harrison, Ludington-Hoe, and White-Traut's research focused on infant stimulation. Holditch-Davis, McCain, McGrath, Medoff-Cooper, Schraeder, and Youngblut studied infant behavior and development. These research programs had many strengths, including strong interdisciplinary focus and clinical relevance. However, additional emphasis is needed on the care of the critically ill infant. Also, despite the fact that the preterm infant's neurological system develops rapidly over the first year, only three of these researchers used a developmental science perspective. Only research on infant behavior and development focused on the developmental changes that the infants were experiencing. Most of the studies were longitudinal, but many did not use statistics appropriate for identifying stability and change over time. The response of individual infants and the broader ecological context as evidenced by factors such as gender, ethnic group, culture, and intergenerational effects were rarely examined. Thus research on the care of preterm infants could be expanded if the developmental science perspective

    Preterm infants are at risk for adverse neurodevelopment. Furthermore, nutrition may play a key role in supporting neurodevelopment. The aim of this study was to evaluate whether a nutrient-enriched formula fed to preterm infants after hospital discharge could improve their neurodevelopment at 24 months (term-corrected age). We conducted an observer-blinded, single-center, randomized controlled trial in infants admitted to the Fondazione IRCCS Cà Granda Ospedale Maggiore Policlinico, University of Milan, Italy between 2009 and 2011. Inclusion criteria were gestational age age, using two computer-generated randomization lists; one appropriate for gestational age (AGA) and one for small for gestational age (SGA) infants. We assessed neurodevelopment at 24 months of corrected age using the Griffiths Mental Development Scale and related subscales (locomotor, personal-social, hearing and speech, hand and eye coordination, and performance). Of the 207 randomized infants, 181 completed the study. 52 AGA and 35 SGA infants were fed a nutrient-enriched formula, whereas 56 AGA and 38 SGA infants were fed a standard full-term formula. The general quotient at 24 months of corrected age was not significantly different between infants randomized to receive a nutrient-enriched formula compared with a standard term formula up until 6 months of corrected age (AGA infants: 93.8 ± 12.6 vs. 92.4 ± 10.4, respectively; SGA infants: 96.1 ± 9.9 vs. 98.2 ± 9, respectively). The scores of related subscales were also similar among groups. This study found that feeding preterm infants a nutrient-enriched formula after discharge does not affect neurodevelopment at 24 months of corrected age, in either AGA or SGA infants, free from major comorbidities.

    Background: The relation between breastfeeding and early motor development is difficult to characterize because of the problems in existing studies such as incomplete control for confounding, retrospective assessment of infant feeding, and even the assessment of some motor skills too early. Objective: We sought to estimate associations between infant feeding and time to achieve major motor milestones in a US cohort. Design: The Upstate New York Infant Development Screening Program (Upstate KIDS Study) enrolled mothers who delivered live births in New York (2008-2010). Mothers of 4270 infants (boys: 51.7%) reported infant motor development at 4, 8, 12, 18, and 24 mo postpartum; information on infant feeding was reported at 4 mo. Accelerated failure time models were used to compare times to standing or walking across feeding categories while adjusting for parental characteristics, daycare, region, and infant plurality, sex, rapid weight gain, and baseline neurodevelopmental test results. Main models were stratified by preterm birth status. Results: The prevalence of exclusive breastfeeding in preterm infants was lower than in term infants at 4 mo postpartum (8% compared with 19%). After adjustment for confounders, term infants who were fed solids in addition to breast milk at 4 mo postpartum achieved both standing [acceleration factor (AF): 0.93; 95% CI: 0.87, 0.99] and walking (AF: 0.93; 95% CI: 0.88, 0.98) 7% faster than did infants who were exclusively breastfed, but these findings did not remain statistically significant after correction for multiple testing. We did not identify feeding-associated differences in motor milestone achievement in preterm infants. Conclusion: Our results suggest that differences in feeding likely do not translate into large changes in motor development.

    Introduction. Transmission of cytomegalovirus (CMV) via breast milk can lead to severe acute illness in very low-birth-weight (VLBW) preterm infants. Although the majority of CMV-seropositive women shed CMV in milk, symptomatic postnatal infection of VLBW infants occurs infrequently, suggesting that virologic or immunologic factors in milk may be associated with the risk and severity of postnatal CMV infection. Methods. We investigated the magnitude of CMV-specific cellular and humoral immune responses in milk of 30 seropositive mothers of VLWB preterm infants and assessed their relationship to milk CMV load and symptomatic CMV transmission. Results. Milk immunoglobulin G (IgG) avidity was inversely correlated to milk CMV load (r = −0.47; P = .009). However, milk CMV load and CMV-specific cellular and humoral immune responses were similar in mothers of VLBW infants with and those without symptomatic postnatal CMV infection. Conclusions. Similar immunologic parameters in milk of CMV-seropositive mothers of VLBW infants with and without symptomatic postnatal CMV infection indicate that screening milk by these parameters may not predict disease risk. However, the inverse correlation between milk CMV IgG avidity and CMV load may suggest that enhancement of maternal CMV-specific IgG responses could aid in reduction of CMV shedding into breast milk.

    Full Text Available Abstract Background Breastfeeding has a major impact on CMV epidemiology. Postnatal CMV reactivation's incidence during lactation is nearby the maternal seroprevalence. Although perinatal CMV infection has practically no consequences in term newborn, it may cause, in some cases, a severe symptomatic disease in preterm newborns. The aims of the present study are to evaluate the rate and clinical expression of CMV infection breast milk transmitted in preterm infants and to check the safety of the freezing treated breast milk. Methods The study included fifty-seven preterm infants and their CMV seropositive mothers. Fresh breast milk samples have been collected from 1st to 9th postpartum week. Both fresh breast milk and 72, 96, 120 hours frozen samples have been examined, checking the presence of CMV; urine samples have been tested too. Results 70.2% of tested mothers showed reactivation of the infection, and CMV-positive breast milk during the six weeks postpartum has been found. However, only one infant was infected by CMV, developing hepatic affection concomitantly with a multi-system involvement, as shown CMV DNA detection in urine, saliva, blood, gastric aspirate, and stools. Conclusion Freezing breast milk at -20°C and pasteurization may respectively reduce or eliminate the viral load.

    Developing interventions that improve deep sleep and quit awake is important to improve the quality of care that is provided to preterm infants. The aim of this study was to compare the effects of kangaroo care and in-arms-holding on the sleep and wake states of preterm infants. A randomized controlled trial design was employed in 2011-2012. Seventy-two stable preterm infants with gestational ages of 32-37 weeks and their mothers were recruited from the neonatal intensive care unit of Valiasr Hospital in Tehran, Iran. Seventy participants completed the trial. In the preintervention phase, nurses placed all of the infants, clad only in diapers, in supine position in their incubator for 20 minutes. Next, the infants in the kangaroo care group were placed onto their mothers' bare chest, whereas those infants in the in-arms-holding group were cradled in their mothers' arms, with the head and back supported by the mother's left arm. The intervention period lasted for 70 minutes. In the postintervention phase, the infants were returned to their incubators and placed in supine position for 20 minutes. The observer recorded the status of the infants during the three phases of study. There were no significant differences between the two groups in terms of state distribution in the preintervention phase. However, the kangaroo care group had longer periods in deep sleep (p preterm infants spend in deep sleep and quiet awake states as compared with simply being held in their mothers' arms. Replication of this research will strengthen the results.

    A population pharmacokinetics/pharmacodynamic (PK/PD) model was developed to describe changes in erythropoiesis as a function of plasma erythropoietin (EPO) concentration over the first 30 days of life in preterm infants who developed severe anemia requiring red blood cell (RBC) transfusion. Several covariates were tested as possible factors influencing the responsiveness to EPO. Discarded blood samples in 27 ventilated preterm infants born at 24-29 wk of gestation were used to construct plasma EPO, hemoglobin (Hb), and RBC concentration-time profiles. The amount of Hb removed for laboratory testing and that transfused throughout the study period were recorded. A population PK/PD model accounting for the dynamic Hb changes experienced by these infants was simultaneously fitted to plasma EPO, Hb, and RBC concentrations. A covariate analysis suggested that the erythropoietic efficacy of EPO is increased for preterm infants at later gestational ages. The PD analysis showed a sevenfold difference in maximum Hb production rate dependent on gestational age and indicated that preterm infants, when stimulated by EPO, have the capacity to produce additional Hb that may result in a decrease in RBC transfusions. The present model has utility in clinical trial simulations investigating the treatment potential of erythropoietic stimulating agents in the treatment of anemia of prematurity.

    Evaluate whether saliva could be a useful alternative to serum for routine therapeutic drug monitoring of caffeine in preterm infants using the enzyme multiplied immunoassay technique (EMIT) assay. We conducted a prospective study including preterm infants (less than 34 weeks' amenorrhea) admitted to the intensive care and neonatal medicine department. All infants received 5, 10, 15, 20 and 25mg/kg/day of citrate caffeine intravenously from the first to the fifth day of birth, respectively. For each patient, two concomitant blood and saliva samples corresponding to the trough concentrations were collected 24hours after each caffeine dose. The caffeine concentrations were determined using the EMIT ® 2000 caffeine assay. Thirteen preterm infants were included. The saliva and the serum caffeine concentration increased proportionally to the administered dose. Saliva and serum kinetics were comparable and the saliva caffeine concentrations were correlated to the serum ones (r 2 =0.76). Saliva caffeine monitoring by EMIT is a valid, useful and safe alternative to serum in preterm infants. Copyright © 2017 Société française de pharmacologie et de thérapeutique.

    Obstructive sleep apnea syndrome (OSA) is a frequent disorder in children. The clinical characteristics of OSA in very young children under 2 years of age, and more particularly, in those born prematurely, and who have respiratory complications such as bronchopulmonary dysplasia (BPD), are not well defined. We therefore retrospectively reviewed our experience in a group of preterm infants with OSAS. The records of premature infants with BPD followed in the Pediatric Pulmonary Clinic at the University of Chicago who were diagnosed with OSA from 2004 to 2009 were reviewed and analyzed. Twelve children, eight males, and four females with a mean gestational age of 27 weeks were found to have OSA. Mean age at diagnosis was 19 months. Inability to wean nighttime oxygen, the need to resume oxygen after intercurrent respiratory illness, and snoring were the most common presenting symptoms. The apnea-hypopnea index ranged from 1 to 120/h total sleep time (TST; mean: 29). SpO(2) nadir ranged from 50 to 91%. Despite adenotonsillectomy (AT), all children had persistent sleep disordered breathing. In preterm infants, while snoring is a frequent symptom, poor weight gain, and inability to wean nighttime oxygen may indicate the need for further investigation for OSA. In the former preterm infant structural changes in the airway may play an important role along with adenotonsillar hypertrophy. A high level of clinical awareness is required to identify OSA in the formerly preterm infant.

    Full Text Available Oxygen saturation is lower during bottle feeding than during breastfeeding in preterm infants. Our objective was to compare two different bottle systems in healthy preterm infants before discharge in terms of SpO2 and oral feeding efficiency (rate of milk intake. Infants without supplement oxygen needs were evaluated twice on the same day during two consecutive feeds, by the same nurse. Infants served as their own controls for comparison of two systems of bottles, the order of which was randomized. The new bottle's nipple design mimics mom's breast in shape and feel, and the bottle vents to air when the child sucks on the nipple. The other system was the hospital's standard plastic bottle with silicone nipple. The rate of milk intake was calculated as the total volume transferred minus volume lost divided by time of feeding, mL/min. Thirty-four infants (BW: 1,163±479.1 g were studied at 35.4±1.3 weeks after-conception. SpO2 was significantly higher in infants fed with the new bottle design. Milk intake rate was significantly higher with the new bottle than with the standard bottle design. The new bottle design improves oral feeding performance in preterm infants near to discharge when compared to that of a standard bottle.

    Full Text Available In an experimental mouse model we showed that ceramides play a role in the pathogenesis of bronchopulmonary dysplasia (BPD and are a potential target for therapeutic intervention. We investigated whether ceramides are detectable in tracheal aspirates (TAs of preterm infants and differ between infants with or without BPD.Infants born ≤ 32 weeks of gestational age in need of mechanical ventilation in the first week of life were included. TAs were obtained directly after intubation and at day 1, 3, 5, 7, and 14. Ceramide concentrations were measured by tandem mass spectrometry. At 36 weeks postmenstrual age BPD was defined as having had ≥ 28 days supplemental oxygen.122 infants were included, of which 14 died and 41 developed BPD. All infants showed an increase in ceramides after the first day of intubation. The ceramide profile differed significantly between preterm infants who did and did not develop BPD. However, the ceramide profile had no additional predictive value for BPD development over GA at birth, birth weight and total days of mechanical ventilation.Ceramides are measurable in TAs of preterm born infants and may be an early marker for BPD development.

    Apnea of prematurity is one of the most common diagnoses in the NICU. Because resolution of apnea is a usual precondition for discharge from the hospital, different monitoring practices might affect length of stay for premature infants. Our objective was to compare the proportion of 33 to 34 weeks' gestational age infants diagnosed with apnea in different NICUs and to assess whether variability in length of stay would be affected by the rate of documented apnea. This was a prospective cohort study of moderately preterm infants who survived to discharge in 10 NICUs in Massachusetts and California. The study population comprised 536 infants born between 33 and 34/7 weeks of which 264 (49%) were diagnosed with apnea. The mean postmenstrual age at discharge was higher in infants diagnosed with apnea compared with those without apnea (36.4 ± 1.3 vs 35.7 ± 0.8; P apnea (range: 24%-76%; P apnea. NICUs vary in the proportion of moderately preterm infants diagnosed with apnea, which significantly affects length of stay. Standardization of monitoring practices and definition of clinically significant cardiorespiratory events could have a significant impact on reducing the length of stay in moderately preterm infants.

    To examine the effect of initiating very early feeding on time-to-reach full feeding in stable, small for gestational age (SGA) preterm infants. Preterm infants with gestational age below 37 weeks and birth weight below the 10(th) percentile were randomly allocated to a very early (within 24 hours of birth) feeding regimen or delayed (after 24 hours of birth) feeding. All infants had in utero evidence of absent or reverse diastolic flow. Infants unable to start early feeding were excluded. Time-to-reach full feeding, feeding progression, and related morbidity were compared. Electrogastrography (EGG) was used to measure pre- and postprandial gastric motility on the second and seventh day after feeding initiation. Sixty infants were included in the study, 30 in each group. Infants included in the very early feeding regimen achieved full enteral feeding sooner than controls (98±80-157 vs. 172±123-261 hours of age, respectively; p= 0.004) and were discharged home earlier (p=0.04). No necrotizing enterocolitis (NEC) was documented in both study groups. Gastric motility was improved at day seven after feeding initiation in both study groups, with no difference between groups. Stable SGA preterm infants on a very early feeding regimen achieved full enteral feeding and were discharged home significantly earlier than those on a delayed regimen, with no excess morbidity.

    Objective To investigate the association of morphine exposure in very preterm infants with cerebral volumes and neurodevelopmental outcome from birth through middle childhood. Study design Observational study of very preterm infants in the Victorian Infant Brain Study cohort. 230 infants born neonatal intensive care unit (NICU) of the Royal Women’s Hospital. 57 (25%) infants received morphine analgesia during their NICU stay at the attending physician’s discretion. Primary outcomes were regional brain volumes at term and 7 years; neurobehavioral performance at term; and cognitive, motor, emotional, behavioral, communication, and executive function scores at age 2 and 7 years. Linear regressions were used to compare outcomes between participants who did and did not receive morphine. Results At term, preterm infants who received morphine had similar rates of grey matter injury to no-morphine infants, but a trend towards smaller cortical volumes in the orbitofrontal (pleft=0.002, pright=0.01) and subgenual (pleft=0.01) regions. At seven years, cortical volumes did not differ between groups. At 2 years, morphine-exposed children were more likely to show behavioral dysregulation (p=0.007) than no-morphine children, but at seven years no detrimental impacts of morphine on neurobehavioral outcome were observed. Conclusions Low-dose morphine analgesia received during neonatal intensive care was associated with early alterations in cerebral structure and short-term neurobehavioral problems that did not persist into childhood.

    To assess retinal nerve fiber layer (RNFL) thickness at term-equivalent age in very preterm (compare very preterm infant RNFL thickness with brain anatomy and neurodevelopment. Cohort study. RNFL was semi-automatically segmented (1 eye per infant) in 57 very preterm and 50 term infants with adequate images from bedside portable, handheld spectral-domain optical coherence tomography imaging at 37-42 weeks postmenstrual age. Mean RNFL thickness was calculated for the papillomacular bundle (-15 degrees to +15 degrees) and temporal quadrant (-45 degrees to +45 degrees) relative to the fovea-optic nerve axis. Brain magnetic resonance imaging (MRI) scans clinically obtained in 26 very preterm infants were scored for global structural abnormalities by an expert masked to data except for age. Cognitive, language, and motor skills were assessed in 33 of the very preterm infants at 18-24 months corrected age. RNFL was thinner for very preterm vs term infants at the papillomacular bundle ([mean ± standard deviation] 61 ± 17 vs 72 ± 13 μm, P brain MRI lesion burden index (R(2) = 0.35, P = .001) and lower cognitive (R(2) = 0.18, P = .01) and motor (R(2) = 0.17, P = .02) scores. Relationships were similar for temporal quadrant. Thinner RNFL in very preterm infants relative to term-born infants may relate to brain structure and neurodevelopment. Copyright © 2015 Elsevier Inc.

The model estimated the cost-effectiveness of LHMF versus PHMF in US$ at 2014/2015 prices.Results: More infants in the LHMF group were discharged home (92% versus 89% and more infants in the PHMF group were transferred to another unit (9% versus 5%. Gestational age was an independent predictor for being discharged home (odds ratio of 2.18; p=0.006 for each week of gestational age. Mean length of neonatal intensive care unit (NICU stay was 1 day less in the LHMF than the PHMF group (62.3 versus 63.4 days, but mean length of NICU stay among infants who developed NEC or sepsis was 79.3 days and 61.2 days in the PHMF and LHMF groups, respectively. Total management cost up to discharge was $10,497 per infant less in the LHMF group than the PHMF group ($240,928 versus $251,425.Conclusion: Using LHMF instead of PHMF in preterm infants enabled resources to be freed-up for alternative use within the system. There is no health economic reason why LHMF should not be used in preference to PHMF

    To define the different breastfeeding interventions that promote breastfeeding exclusivity and duration in the late preterm infant and to synthesize findings from the published empirical literature on late preterm infant breastfeeding interventions. The databases CINAHL, Scopus, and PubMed were searched for primary research articles on breastfeeding interventions for late preterm infants. Inclusion criteria included original research studies in which authors examined a breastfeeding intervention or second-line strategy in a sample inclusive of but not necessarily limited to the gestational age range of 34 to 3667 weeks gestation, written in English, and published between 2005 and 2015. Thirteen articles were identified, including five randomized controlled trials, three quasi-experimental studies, four descriptive studies, and one case study. Whittemore and Knafl's methodology guided this integrative review. Data extraction and organization occurred under the following headings: author and year, study design, level of evidence, purpose, sample, setting, results, limitations, recommendations, and intervention. Studies on breastfeeding interventions were synthesized under four concepts within the Late Preterm Conceptual Framework: Physiologic Functional Status, Care Practices, Family Role, and Care Environment. Most breastfeeding interventions within this integrative review had positive effects on exclusivity and duration of breastfeeding in the late preterm infant. However, second-line strategies had equivocal effects on exclusivity but had positive effects on duration. The positive effects of breastfeeding interventions on breastfeeding exclusivity and duration are highlighted in our results, and we point to the need for a focus on breastfeeding after the transition home for late preterm infants.

    OBJECTIVE: To develop a homologous human milk supplement for very low-birth weight infant feeding, using an original and simplified methodology, to know the nutritional composition of human milk fortified with this supplement and to evaluate its suitability for feeding these infants. METHODS: For the production and analysis of human milk with the homologous additive, 25 human milk samples of 45mL underwent a lactose removal process, lyophilization and then were diluted in 50mL of human milk. Measurements of lactose, proteins, lipids, energy, sodium, potassium, calcium, phosphorus and osmolality were performed. RESULTS: The composition of the supplemented milk was: lactose 9.22±1.00g/dL; proteins 2.20±0.36g/dL; lipids 2.91±0.57g/dL; calories 71.93±8.69kcal/dL; osmolality 389.6±32.4mOsmol/kgH2O; sodium 2.04±0.45mEq/dL; potassium 1.42±0.15mEq/dL; calcium 43.44±2.98mg/dL; and phosphorus 23.69±1.24mg/dL. CONCLUSIONS: According to the nutritional contents analyzed, except for calcium and phosphorus, human milk with the proposed supplement can meet the nutritional needs of the very low-birth weight preterm infant.

    Boykova, Marina

    Transition from hospital to home is a complex and multidimensional phenomenon for parents of prematurely born infants (EBSCO) was performed. Fifty selected reports of research conducted on parents of preterm infants during 1980-2014 are included in this article. Five themes emerged from the review-disruption of parental role development, distorted development of parent-infant relationships, psychological consequences of a preterm birth and infant hospitalization, learning caregiving and parenting, and need for social and professional supports-which appear to reflect parental challenges during transition from hospital to home after discharge. Several inconsistencies in results of the studies dictate the need for further research in this vulnerable population; the better conceptualization and measurement of transitional challenges are warranted.

    The Assessment of Preterm Infants' Behavior (APIB) is a newborn neurobehavioral assessment appropriate for preterm, at risk, and full-term newborns, from birth to 1 month after expected due date. The APIB is based in ethological-evolutionary thought and focuses on the assessment of mutually interacting behavioral subsystems in simultaneous interaction with the environment. The subsystems of functioning assessed include the autonomic (respiration, digestion, color), motor (tone, movement, postures), state organization (range, robustness, transition patterns), attention (robustness, transitions), and self-regulation (effort, success) systems as well as the degree of facilitation required to support reorganization and subsystem balance. The environment is represented by a sequence of distal, proximal, tactile, and vestibular challenges, derived from the BNBAS. The APIB conceptualizes infant competence as the degree of differentiation of subsystem function and degree of modulation of subsystem balan
