    Premature birth is a significant cause of infant and child morbidity and mortality. In the United States, the premature birth rate, which had steadily increased during the 1990s and early 2000s, has decreased annually for 7 years and is now approximately 11.39%. Human viability, defined as gestational age at which the chance of survival is 50%, is currently approximately 23 to 24 weeks in developed countries. Infant girls, on average, have better outcomes than infant boys. A relatively uncomplicated course in the intensive care nursery for an extremely premature infant results in a discharge date close to the prenatal estimated date of confinement. Despite technological advances and efforts of child health experts during the last generation, the extremely premature infant (less than 28 weeks gestation) and extremely low birth weight infant (<1000 g) remain at high risk for death and disability with 30% to 50% mortality and, in survivors, at least 20% to 50% risk of morbidity. The introduction of continuous positive airway pressure, mechanical ventilation, and exogenous surfactant increased survival and spurred the development of neonatal intensive care in the 1970s through the early 1990s. Routine administration of antenatal steroids during premature labor improved neonatal mortality and morbidity in the late 1990s. The recognition that chronic postnatal administration of steroids to infants should be avoided may have improved outcomes in the early 2000s. Evidence from recent trials attempting to define the appropriate target for oxygen saturation in preterm infants suggests arterial oxygen saturation between 91% and 95% (compared with 85%-89%) avoids excess mortality; however, final analyses of data from these trials have not been published, so definitive recommendations are still pending. The development of neonatal neurocritical intensive care units may improve neurocognitive outcomes in this high-risk group. Long-term follow-up to detect and address

    The purpose of this longitudinal qualitative descriptive study was to explore American Indian (AI) mothers’ perceptions of parenting their premature infants over their first year of life in the context of their culture, including the birth and hospitalization experience. A convenience sample of 17 AI mothers and their premature infants were recruited from either a neonatal intensive care unit (NICU) or pediatric clinic in the southeast. Semistructured interviews were conducted at two time points. Through content analytic methods, three broad categories were revealed: descriptions of having a premature infant in the NICU, descriptions of parenting a premature infant, and the influence of Lumbee culture on parenting a premature infant. Certain aspects of AI culture appear to be important in having a premature infant in the NICU and in parenting a premature infant. We recommend that healthcare providers deliver culturally appropriate care that fully supports AI mothers and their premature infants. PMID:25721716

    Infants born preterm are at a higher risk of complications and hospitalization in cases of rotavirus diarrhea than children born at term. We evaluated the impact of a rotavirus vaccination campaign (May 2007 to May 2010) on hospitalizations for rotavirus gastroenteritis in a population of children under 3 years old born prematurely (before 37 weeks of gestation) in the Brest University Hospital birth zone. Active surveillance from 2002 to 2006 and a prospective collection of hospitalizations for rotavirus diarrhea were initiated in the pediatric units of Brest University Hospital until May 2010. Numbers of hospitalizations for rotavirus diarrhea among the population of children born prematurely, before and after the start of the vaccination program, were compared using a Poisson regression model controlling for epidemic-to-epidemic variation. A total of 217 premature infants were vaccinated from 2007 to 2010. Vaccine coverage for a complete course of three doses was 41.9%. The vaccine safety in premature infants was similar to that in term infants. The vaccination program led to a division by a factor of 2.6 (95% confidence interval [CI], 1.3 to 5.2) in the number of hospitalizations for rotavirus diarrhea during the first two epidemic seasons following vaccine introduction and by a factor of 11 (95% CI, 3.5 to 34.8) during the third season. We observed significant effectiveness of the pentavalent rotavirus vaccine on the number of hospitalizations in a population of prematurely born infants younger than 3 years of age. A multicenter national study would provide better assessment of this impact. (This study [Impact of Systematic Infants Vaccination Against Rotavirus on Gastroenteritis Hospitalization: a Prospective Study in Brest District, France (IVANHOE)] has been registered at ClinicalTrials.gov under registration no.

    To ascertain whether touch, in the form of extra tactile stimulation, would result in more rapid physical and social development and a greater degree of social development of the premature infant, 48 minutes of extra tactile stimulation, defines as a gentle, nonrhythmic stroking of the greatest possible area of skin surface of the infant's body by the nurse's hand, was given to eight experimental group premature infants daily for a minimum of two weeks while they were confined to an isolette. Six infants formed a control group. Regain of birth weight was used to assess physical development. Scores on the applicable portions of the Gesell Development Schedule and Bayley Scales of Infant Development and plasma cortisol levels were used to measure rate and degree of social development. Data were analyzed in terms of the total group and for pairs of infants matched for gestational age, birth weight, and Apgar score. No significant difference was found between control and experimental groups in rate of physical development as measured by regain of birth weight. Analysis of the relationship between weight gain and gestational age, sex, and Apgar scores indicated that none was a substantial indicator of the rate at which infants gained weight while in the hospital. There was no significant difference in the degree of social development between experimental and control infants, but, as hypothesized, there was significant difference in rate of social development. Plasma cortisol levels as an indication of the infant's adrenocorticol development as evidenced by his ability to respond to stressful situations, and hence indirectly his social development, revealed no significant difference between the two groups.

  14. Neurodevelopmental outcomes of infants born prematurely.

    PubMed

    Aylward, Glen P

    2014-01-01

    Long-term follow-up of infants born prematurely is necessary to determine neurodevelopmental outcomes, particularly with the expansion of interest from major disabilities to high prevalence/low severity dysfunctions. Models of pathogenesis include changes due to developmental disruptions and to injury, the magnitude and type of change influenced by the infant's age, and central nervous system recovery and reorganization. Alterations in neurogenesis, migration, myelination, cell death, and synaptogenesis occur even in the absence of insult. Despite increased knowledge regarding these processes, the functional significance of brain abnormalities is unclear. Because of methodologic problems in follow-up studies, it is difficult to characterize outcome definitively. Nonetheless, an acceptable degree of agreement across studies is found with regard to specific neurodevelopmental outcomes: motor/neurologic function, visuomotor integrative skills, IQ, academic achievement, language, executive function, and attention-deficit hyperactivity disorder/behavioral issues. In general, children born prematurely have more problems in these areas than do their normal birth weight counterparts. Suggestions for improved analyses and clarification of outcomes include use of cluster analysis, structural equation modeling, growth curve analysis, developmental epidemiologic approaches, and better control of background variables using risk indexes and factor scores. Better assessment techniques measuring functions documented to be at higher risk of problems are discussed. PMID:25007063

    Objective To compare the interactive behaviors of American Indian mothers and their premature infants with those of African American mothers and their premature infants. Design Descriptive, comparative study. Setting Three neonatal intensive care units and two pediatric clinics in the southeast. Participants Seventy-seven mother-infant dyads: 17 American Indian mother-infant dyads and 60 African American mother-infant dyads. Methods Videotapes of mother-infant interactions and the Home Observation for Measurement of the Environment (HOME) were used to assess the interactions of the mothers and their premature infants at six months corrected age. Results American Indian mothers looked more, gestured more, and were more often the primary caregivers to their infants than the African American mothers. American Indian infants expressed more positive affect and gestured more to their mothers, whereas African American infants engaged in more non-negative vocalization toward their mothers. African American mothers scored higher on the HOME subscales of provision of appropriate play materials and parental involvement with the infant. American Indian mothers scored higher on the opportunities for variety in daily living subscale. Conclusion Although many of the interactive behaviors of American Indian and African American mother-infant dyads were similar, some differences did occur. Clinicians need to be aware of the cultural differences in mother-infant interactions. To optimize child developmental outcomes, nurses need to support mothers in their continuation or adoption of positive interactive behaviors. PMID:23682698

    2012-04-23

    Premature birth rates and premature infant morbidity remain discouragingly high. Improving nourishment for these infants is the key for accelerating their development and decreasing disease risk. Dietary protein is essential for growth and development of infants. Studies on protein nourishment for premature infants have focused on protein requirements for catch-up growth, nitrogen balance, and digestive protease concentrations and activities. However, little is known about the processes and products of protein digestion in the premature infant. This review briefly summarizes the protein requirements of term and preterm infants, and the protein content of milk from women delivering preterm and at term. An in-depth review is presented of the current knowledge of term and preterm infant dietary protein digestion, including human milk protease and anti-protease concentrations; neonatal intestinal pH, and enzyme activities and concentrations; and protein fermentation by intestinal bacteria. The advantages and disadvantages of incomplete protein digestion as well as factors that increase resistance to proteolysis of particular proteins are discussed. In order to better understand protein digestion in preterm and term infants, future studies should examine protein and peptide fragment products of digestion in saliva, gastric, intestinal and fecal samples, as well as the effects of the gut micro biome on protein degradation. The confluence of new mass spectrometry technology and new bioinformatics programs will now allow thorough identification of the array of peptides produced in the infant as they are digested.

    Invasive candidiasis is a leading infectious cause of morbidity and mortality in premature infants. Improved recognition of modifiable risk factors and antifungal prophylaxis have contributed to the recent decline in the incidence of this infection among infants. Invasive candidiasis typically occurs in the first six weeks of life and presents with non-specific signs of sepsis. Definitive diagnosis relies on growth of Candida in blood culture or cultures from other normally sterile sites, but this may identify fewer than half of cases. Improved diagnostics are needed to guide initiation of antifungal therapy in premature infants. PMID:25677999

  1. Clinical assessment of bilirubin-induced neurotoxicity in premature infants.

    The clinical assessment of bilirubin-induced neurotoxicity in premature infants remains difficult in the absence of a gestational age-specific total or free (unbound) bilirubin level that predicts bilirubin-induced neurotoxicity. Because the total serum bilirubin concentration is an unreliable predictor of bilirubin-induced neurotoxicity in premature infants, alternative mean for predicting bilirubin-induced neurotoxicity in jaundiced preterm newborns is needed. Over the last few years, we have witnessed substantial gain in our knowledge involving usefulness of bilirubin-binding variables (total bilirubin, free bilirubin, bilirubin:albumin molar ratio) for clinical assessment of bilirubin-induced neurotoxicity in preterm infants. The knowledge gained has provided impetus for more clinical studies that are geared toward confirming the usefulness of free bilirubin as a predictor of bilirubin-induced neurotoxicity and identifying the gestational age-specific free bilirubin level that may increase the risk of bilirubin-induced neurotoxicity in premature infants. The paper has attempted to provide an overview of bilirubin-induced auditory toxicity along with the existing clinical evidence in favor of free bilirubin assay and usefulness of auditory brainstem evoked response for evaluation of bilirubin-induced neurotoxicity in premature infants. In addition, the author has described findings that suggest an association of apnea, a clinical manifestation, with acute bilirubin encephalopathy in premature infants. PMID:15686265

    Vitamin A is a fat-soluble vitamin, and it is not only necessary for the normal growth and development of epithelial cells, but also plays a very important role in the normal growth and development of the retina, lungs, gastrointestinal tract, brain, and immune system. Studies have confirmed that the low level of vitamin A in premature infants at birth can last through the entire infancy. Recently, there have been particular concerns about the level of vitamin A and development of diseases in premature infants, with major focuses on the related mechanisms of action of vitamin A in respiratory distress syndrome, chronic lung disease, retinopathy of prematurity, necrotizing enterocolitis, patent ductus arteriosus, and infections in premature infants, which still awaits further investigation.This paper summarizes and analyzes the current status of research on vitamin A level and diseases of premature infants at home and abroad. In addition, although enough evidence suggests that vitamin A supplementation is beneficial to preterm infants, evidence is still lacking for recommended methods for supplementation and dose of vitamin A, and further studies are needed.

    The initial attachment of three mothers to three premature infants weighing less than 1500 g was assessed by observation of the mother's behaviour during visits to her child in the hospital nursery. Interactions of mothers and infants were compared with those of nurses and infants. Premature infants, during a stay in hospital of approximately 7 weeks, have to adapt to up to 70 different nurses and receive generally little contact stimulation from them. Mothers change in their interactional behaviour over time but show persistent individual differences in amount of touching, smiling and talking to their infants. Follow-up investigation will determine if the maternal behaviour as demonstrated in the nursery is predictive of later parenting disorders. PMID:803124

    Necrotizing enterocolitis (NEC) is a severe form of bowel disease that develops in premature infants. Although animal data and human studies suggest that aberrant activation of the intestinal immune system contributes to NEC, the pathogenesis remains unclear. We hypothesized that inherited defects in the regulation of Toll-like receptor signaling can contribute to NEC susceptibility in premature infants. A forward genetic screen done in an infant with lethal NEC using exome sequencing identified a novel stop mutation (p.Y168X) and a rare missense variant (p.S80Y) in SIGIRR, a gene that inhibits intestinal Toll-like receptor signaling. Functional studies carried out in human embryonic kidney cells and intestinal epithelial cells demonstrated that SIGIRR inhibited inflammation induced by lipopolysaccharide, a cell wall component of Gram-negative bacteria implicated in NEC. The genetic variants identified in the infant with NEC resulted in loss of SIGIRR function and exaggerated inflammation in response to lipopolysaccharide. Additionally, Sanger sequencing identified missense, stop, or splice region SIGIRR variants in 10 of 17 premature infants with stage II+ NEC. To the best of our knowledge, this is one of the first reports of a phenotype associated with SIGIRR in humans. Our data provide novel mechanistic insight into the probable causation of NEC and support additional investigation of the hypothesis that inherited defects in the regulation of innate immune signaling can contribute to NEC susceptibility in premature infants.

    The authors present beneficial effects and possible disadvantages of early enteral feeding of prematurely born infants. Also, the indications for maintaining enteral feeding in patients with sepsis are discussed. Breast milk is known to accelerate the process of maturation of alimentary tract as well as to improve the digestion of food compounds. Additionally, it protects the infant against bacterial translocations from gut to the blood stream and reduces the risk of sepsis in newborns, especially in very low birth weight infants. Finally, the authors formulate preliminary recommendations for enteral feeding of septic newborn infants. PMID:19471066

    Context: Prematurely born children have a high risk of developmental and behavioral disabilities. Cerebral abnormalities at term age have been clearly linked with later behavior alterations, but existing studies did not focus on the amygdala. Moreover, studies of early amygdala development after premature birth in humans are scarce. Objective: To compare amygdala volumes in very preterm infants at term equivalent age (TEA) and term born infants, and to relate premature infants’ amygdala volumes with their performance on the Laboratory Temperament Assessment Battery (Lab-TAB) fear episode at 12 months. Participants: Eighty one infants born between 2008 and 2014 at the University Hospitals of Geneva and Lausanne, taking part in longitudinal and functional imaging studies, who had undergone a magnetic resonance imaging (MRI) scan at TEA enabling manual amygdala delineation. Outcomes: Amygdala volumes assessed by manual segmentation of MRI scans; volumes of cortical and subcortical gray matter, white matter and cerebrospinal fluid (CSF) automatically segmented in 66 infants; scores for the Lab-TAB fear episode for 42 premature infants at 12 months. Results: Amygdala volumes were smaller in preterm infants at TEA than term infants (mean difference 138.03 mm3, p < 0.001), and overall right amygdala volumes were larger than left amygdala volumes (mean difference 36.88 mm3, p < 0.001). White matter volumes were significantly smaller (p < 0.001) and CSF volumes significantly larger (p < 0.001) in preterm than in term born infants, while cortical and subcortical gray matter volumes were not significantly different between groups. Amygdala volumes showed significant correlation with the intensity of the escape response to a fearsome toy (rs = 0.38, p = 0.013), and were larger in infants showing an escape response compared to the infants showing no escape response (mean difference 120.97 mm3, p = 0.005). Amygdala volumes were not significantly correlated with the intensity

    Objectives The ability of the premature brain to extract and use oxygen has not been studied adequately. This study aimed to determine factors that influence fractional tissue oxygen extraction (FTOE) of the brain in premature infants using near-infrared spectroscopy (NIRS) and pulse oximetry. Study Design We prospectively studied FTOE in very low birth weight (BW) infants (< 1,500 g and ≤ 34 weeks' gestation). Factors affecting FTOE and its variability were examined using bivariate and linear regression models. FTOE variability was measured on two scales: short scales (3-20 seconds) and long scales (20-150 seconds). Results We examined 147 simultaneous NIRS and pulse oximetry recordings that were collected from 72 premature infants (gestational age [GA] = 28 weeks and BW = 1,036 g). In regression models, average FTOE correlated negatively with hemoglobin (Hb) and increased significantly in patients with severe intraventricular hemorrhage/periventricular leukomalacia. Both FTOE short- and long-scale variabilities correlated negatively with GA and positively with postnatal age (PNA). Moreover, FTOE long-scale variability was significantly reduced in infants supported with invasive ventilation. Conclusions In premature infants, cerebral oxygen extraction increased with reduced Hb and severe brain injury. Variability in oxygen extraction showed differential changes with GA and PNAs and was affected by invasive ventilation. PMID:26906179

    2014-08-15

    Preterm births (deliveries before 37 weeks' gestation) comprise 12% of all U.S. births and are responsible for onethird of all infant deaths. Neonatal medical advances have increased survival, and primary care physicians often care for infants who were in the neonatal intensive care unit after birth. Functions of the primary care physician include coordination of medical and social services, nutritional surveillance, and managing conditions associated with prematurity. Parental guidance and encouragement are often necessary to ensure appropriate feeding and infant weight gain. Enriched formula and nutrient fortifiers are used for infants with extrauterine growth restriction. Iron supplementation is recommended for breastfed infants, and iron-fortified formula for formula-fed infants. Screening for iron deficiency anemia in preterm infants should occur at four months of age and at nine to 12 months of age. Gastroesophageal reflux is best treated with nonpharmacologic options because medications provide no long-term benefits. Neurodevelopmental delay occurs in up to 50% of preterm infants. Developmental screening should be performed at every well-child visit. If developmental delay is suspected, more formalized testing may be required with appropriate referral. To prevent complications from respiratory syncytial virus infection, palivizumab is recommended in the first year of life during the respiratory syncytial virus season for all infants born before 29 weeks' gestation and for infants born between 29 and 32 weeks' gestation who have chronic lung disease. Most preterm infants have minimal longterm sequelae. PMID:25250998

    A preterm infant of 30 weeks gestation developed thrombosis of the left arteria femoralis on his fourth day of life. Continuous intravenous heparinization with 350 to 750 U/kg bw/d was performed during the course of several weeks.

    2014-01-01

    Microminerals, including iron, zinc, copper, selenium, manganese, iodine, chromium and molybdenum, are essential for a remarkable array of critical functions and need to be supplied in adequate amounts to preterm infants. Very low birth weight (VLBW) infants carry a very high risk of developing iron deficiency which can adversely affect neurodevelopment. However, a too high iron supply in iron-replete VLBW infants may induce adverse effects such as increased infection risks and impaired growth. Iron needs are influenced by birth weight, growth rates, blood losses (phlebotomy) and blood transfusions. An enteral iron intake of 2 mg/kg/day for infants with a birth weight of 1,500-2,500 g and 2-3 mg/kg/day for VLBW infants is recommended. Higher doses up to 6 mg/kg/day are needed in infants receiving erythropoietin treatment. Regular monitoring of serum ferritin during the hospital stay is advisable. Routine provision of iron with parenteral nutrition for VLBW infants is not recommended. Less certainty exists for the advisable intakes of other microminerals. It appears prudent to provide enterally fed VLBW infants with daily amounts per kilogram body weight of 1.4-2.5 mg zinc, 100-230 μg copper, 5-10 μg selenium, 1-15 μg manganese, 10-55 μg iodine, 0.03-2.25 μg chromium, and 0.3-5 μg molybdenum. Future scientific findings may justify deviations from these suggested ranges. PMID:24751625

    Background Periodic breathing (PB), regular cycles of short apneic pauses and breaths, is common in newborn infants. To characterize normal and potentially pathologic PB, we used our automated apnea detection system and developed a novel method for quantifying PB. We identified a preterm infant who died of SIDS and who, on review of her breathing pattern while in the NICU, had exaggerated PB. Methods We analyzed the chest impedance signal for short apneic pauses and developed a wavelet transform method to identify repetitive 10–40 second cycles of apnea/breathing. Clinical validation was performed to distinguish PB from apnea clusters and determine the wavelet coefficient cutoff having optimum diagnostic utility. We applied this method to analyze the chest impedance signals throughout the entire NICU stays of all 70 infants born at 32 weeks’ gestation admitted over a two-and-a-half year period. This group includes an infant who died of SIDS and her twin. Results For infants of 32 weeks’ gestation, the fraction of time spent in PB peaks 7–14 days after birth at 6.5%. During that time the infant that died of SIDS spent 40% of each day in PB and her twin spent 15% of each day in PB. Conclusions This wavelet transform method allows quantification of normal and potentially pathologic PB in NICU patients. PMID:26012526

    Safe anesthesia in premature and ex-premature infants remains a challenge for the anesthesiologist. These infants are at risk of postoperative apnea, desaturation, and bradycardia after general anesthesia. We describe our experience of peribulbar block in 24 infants who underwent vitreoretinal surgery for retinopathy of prematurity. None of our patients had postoperative apnea or required neonatal intensive care admission. A possible opioid and muscle relaxant-sparing effect of peribulbar block might have reduced the incidence of postoperative complications. PMID:26556110

    The recently developed technique of gas chromatography-mass spectrometry supported by computer has considerably improved the analysis of physiologic fluids. This study attempted to demonstrate the value of this system in the investigation of metabolite patterns in urine in two metabolic problems of prematurity, transient tyrosinemia and late metabolic acidosis. Serial 24-hr urine specimens were analyzed in 9 infants. Transient tyrosinemia, characterized by 5- 10-fold increases over basal excretion of tyrosine, p-hydroxyphenyllactate, and p-hydroxyphenylpyruvate in urine, was noted in five of the infants. Late metabolic acidosis was seen in four infants, but bore no relation to transient tyrosinemia.

    To evaluate the central corneal thickness (CCT) and intraocular pressure (IOP) of premature infants and to document correlation of them with gestational age, chronological age, and birth weight of infants. Using a hand-held applanation tonometer and a portable pachymeter, IOP and CCT of 170 premature infants were measured just before initial retinopathy of prematurity screening examination and re-measured 4 weeks after the first visit. The CCT and IOP were positively correlated during the first (r = 0.616, p < 0.001) and second (r = 0.564, p < 0.001) visits. The mean CCT at first and second visits were 568.1 ± 22.1 (527-628) and 561.6 ± 21.4 (520-619) µm, consecutively (p < 0.001). Gestational age, chronological age and birth weight of infants were found to be negatively correlated with CCT at first (r = -0.751, p < 0.001; r = -0.745, p < 0.001; r = -0.581, p < 0.001, consecutively) and second (r = -0.729, p < 0.001; r = -0.729, p < 0.001; r = -0.555, p < 0.001, consecutively) visits. The mean IOP at first and second visits were 14.1 ± 1.9 (11-19) and 13.7 ± 1.7 (11-18) mmHg, consecutively (p < 0.001). Gestational age, chronological age, and birth weight of infants were found to be negatively correlated with IOP at first (r = -0.724, p < 0.001; r = -0.715, p < 0.001; r = -0.558, p < 0.001, consecutively) and second (r = -0.704, p < 0.001; r = -0.703, p < 0.001; r = -0.518, p < 0.001, consecutively) visits. CCT and IOP of the premature infants with a smaller gestational age were found to be higher (p < 0.001 for both). Premature infants with smaller gestational age have higher CCT and IOP values when compared to older infants. These values tend to become lower 4 weeks after the first examination as infants become older. The CCT and IOP were positively correlated with each other and both were negatively correlated with gestational age, chronological age, and birth weight during first and second visits. PMID:26286757

    Introduction The research in long latency auditory evokes potentials (LLAEP) in newborns is recent because of the cortical structure maturation, but studies note that these potentials may be evidenced at this age and could be considered as indicators of cognitive development. Purpose To research the exogenous potentials in term and premature infants during their first month of life. Materials and Methods The sample consisted of 25 newborns, 15 term and 10 premature infants. The infants with gestational age under 37 weeks were considered premature. To evaluate the cortical potentials, the infants remained in natural sleep. The LLAEPs were researched binaurally, through insertion earphones, with frequent /ba/ and rare /ga/ speech stimuli in the intensity of 80 dB HL (decibel hearing level). The frequent stimuli presented a total of 80% of the presentations, and the rare, 20%. The data were statistically analyzed. Results The average gestational age of the term infants was 38.9 weeks (± 1.3) and for the premature group, 33.9 weeks (± 1.6). It was possible to observe only the potentials P1 and N1 in both groups, but there was no statistically significant difference for the latencies of the components P1 and N1 (p > 0.05) between the groups. Conclusion It was possible to observe the exogenous components P1 and N1 of the cortical potentials in both term and preterm newborns of no more than 1 month of age. However, there was no difference between the groups. PMID:25992057

    Very preterm infants are at risk of neurodevelopmental impairments, which may affect motor development, intelligence and behavior. Neurodevelopmental follow-up is offered to these children who represent 1% of Swiss births, and may show abnormal motor tone, which sometimes resolves spontaneously or evolves in cerebral palsy. Standardized tests explore intellectual functioning and may allow the diagnosis of specific learning impediments. Finally, behavior is assessed with standardized questionnaires which can reveal hyperactivity with or without attention deficit, impaired social relations, psychiatric troubles or autism, all more frequent amongst preterm children.

    Background. Necrotizing enterocolitis (NEC) is a devastating inflammatory bowel disease of premature infants speculatively associated with infection. Suspected NEC can be indistinguishable from sepsis, and in established cases an infant may die within hours of diagnosis. Present treatment is supportive. A means of presymptomatic diagnosis is urgently needed. We aimed to identify microbial signatures in the gastrointestinal microbiota preceding NEC diagnosis in premature infants. Methods. Fecal samples and clinical data were collected from a 2-year cohort of 369 premature neonates. Next-generation sequencing of 16S ribosomal RNA gene regions was used to characterize the microbiota of prediagnosis fecal samples from 12 neonates with NEC, 8 with suspected NEC, and 44 controls. Logistic regression was used to determine clinical characteristics and operational taxonomic units (OTUs) discriminating cases from controls. Samples were cultured and isolates identified using matrix-assisted laser desorption/ionization–time of flight. Clostridial isolates were typed and toxin genes detected. Results. A clostridial OTU was overabundant in prediagnosis samples from infants with established NEC (P = .006). Culture confirmed the presence of Clostridium perfringens type A. Fluorescent amplified fragment-length polymorphism typing established that no isolates were identical. Prediagnosis samples from NEC infants not carrying profuse C. perfringens revealed an overabundance of a Klebsiella OTU (P = .049). Prolonged continuous positive airway pressure (CPAP) therapy with supplemental oxygen was also associated with increased NEC risk. Conclusions. Two fecal microbiota signatures (Clostridium and Klebsiella OTUs) and need for prolonged CPAP oxygen signal increased risk of NEC in presymptomatic infants. These biomarkers will assist development of a screening tool to allow very early diagnosis of NEC. Clinical Trials Registration. NCT01102738. PMID:25344536

    Our preliminary data show high levels of adenosine in the blood of very low birth weight (VLBW) infants, positively correlating to their prematurity (i.e. body weight class). This prompted us to look for a mechanism promoting such impressive adenosine increase. We hypothesized a correlation with oxygen challenge. In fact, it is recognized that either oxygen lack or its excess contribute to the pathogenesis of the injuries of prematurity, such as retinopathy (ROP) and periventricular white matter lesions (PWMI). The optimal concentration of oxygen for resuscitation of VLBW infants is currently under revision. We propose that the elevated adenosine blood concentrations of VLBW infants recognizes two sources. The first could be its activity-dependent release from unmyelinated brain axons. Adenosine in this respect would be an end-product of the hypometabolic VLBW newborn unmyelinated axon intensely firing in response to the environmental stimuli consequent to premature birth. Adenosine would be eventually found in the blood due to blood-brain barrier immaturity. In fact, adenosine is the primary activity-dependent signal promoting differentiation of premyelinating oligodendrocyte progenitor cells (OPC) into myelinating cells in the Central Nervous System, while inhibiting their proliferation and inhibiting synaptic function. The second, would be the ecto-cellular ATP synthesized by the endothelial cell plasmalemma exposed to ambient oxygen concentrations due to premature breathing, especially in lung. ATP would be rapidly transformed into adenosine by the ectonucleotidase activities such as NTPDase I (CD39), and NT5E (CD73). An ectopic extra-mitochondrial aerobic ATP synthetic ability was reported in many cell plasma-membranes, among which endothelial cells. The potential implications of the cited hypotheses for the neonatology area would be great. The amount of oxygen administration for reviving of newborns would find a molecular basis for its assessment. VLBW

    Relapsing fever is caused by the Borrelia species of spirochetes. Louse-born epidemics of the disease may occur but the endemic disease is usually transmitted to humans by the bite of an infected tick (Ornithodorus). Transplacental infection was suggested more than 75 years ago (1) but has been rarely documented (2). We describe a case of neonatal relapsing fever where maternal infection was the probable cause of the premature delivery and infection in the infant. PMID:2415056

Clinical research on CPAP has primarily focused on understanding which devices and pressure sources best implement this therapy. In contrast, less research has examined the optimal duration over which CPAP is administered. We review this aspect of CPAP therapy. PMID:26948885

    For the first time, three-dimensional images of the newborn infant brain have been generated using measurements of transmitted light. A 32-channel time-resolved imaging system was employed, and data were acquired using custom-made helmets which couple source fibres and detector bundles to the infant head. Images have been reconstructed using measurements of mean flight time relative to those acquired on a homogeneous reference phantom, and using a head-shaped 3D finite-element-based forward model with an external boundary constrained to match the measured positions of the sources and detectors. Results are presented for a premature infant with a cerebral haemorrhage predominantly located within the left ventricle. Images representing the distribution of absorption at 780 nm and 815 nm reveal an asymmetry consistent with the haemorrhage, and corresponding maps of blood volume and fractional oxygen saturation are generally within expected physiological values.

    Background. In premature infants, maintaining blood partial pressure of carbon dioxide (pCO2) value within a narrow range is important to avoid cerebral lesions. The aim of this study was to assess the accuracy of a noninvasive transcutaneous method (TcpCO2), compared to blood partial pressure of carbon dioxide (pCO2). Methods. Retrospective observational study in a tertiary neonatal intensive care unit. We analyzed the correlation between blood pCO2 and transcutaneous values and the accuracy between the trends of blood pCO2 and TcpCO2 in all consecutive premature infants born at <33 weeks' gestational age. Results. 248 infants were included (median gestational age: 29 + 5 weeks and median birth weight: 1250 g), providing 1365 pairs of TcpCO2 and blood pCO2 values. Pearson's R correlation between these values was 0.58. The mean bias was −0.93 kPa with a 95% confidence limit of agreement of −4.05 to +2.16 kPa. Correlation between the trends of TcpCO2 and blood pCO2 values was good in only 39.6%. Conclusions. In premature infants, TcpCO2 was poorly correlated to blood pCO2, with a wide limit of agreement. Furthermore, concordance between trends was equally low. We warn about clinical decision-making on TcpCO2 alone when used as continuous monitoring. PMID:27375901

    Objective To compare effectiveness of three surfactant preparations (beractant, calfactant, and poractant alpha) in premature infants for preventing three outcomes: (1) air leak syndromes; (2) death; and (3) bronchopulmonary dysplasia (BPD) or death (composite outcomes). Study design We conducted a comparative effectiveness study of premature infants admitted to 322 neonatal intensive care units in the U.S. from 2005–2010 who were treated with beractant, calfactant, or poractant alfa. We compared the incidence of air leak syndromes, death, and bronchopulmonary dysplasia (BPD) or death, adjusting for gestational age, antenatal steroids, discharge year, and small-for-gestational-age status. Results 51,282 infants received surfactant; 40% received beractant, 30% calfactant, and 30% poractant alfa. Median birth weight was 1435 g (interquartile range 966–2065); median gestational age was 30 weeks (27–33). On adjusted analysis, we observed a similar risk of air leak syndromes (calfactant vs. beractant odds ratio [OR]=1.17 [95% confidence interval: 0.95, 1.43]; calfactant vs. poractant OR=1.23 [0.98, 1.56]; beractant vs. poractant OR=1.06 [0.87, 1.29]), death (calfactant vs. beractant OR=1.14 [0.93, 1.39]; calfactant vs. poractant OR=0.98 [0.78, 1.23]; beractant vs. poractant OR=0.86 [0.72, 1.04]), and BPD or death (calfactant vs. beractant OR=1.08 [0.93, 1.26]; calfactant vs. poractant OR=1.19 [1.00, 1.41]; beractant vs. poractant OR=1.10 [0.96, 1.27]). Conclusions Beractant, calfactant, and poractant alfa demonstrated similar effectiveness in prevention of air leak syndromes, death, and BPD or death in premature infants when adjusted for site. Previously described differences in mortality between surfactants likely do not represent true differences in effectiveness but may relate to site variation in outcomes. PMID:23769501

    A prerequisite for the further improvement in the quality of warming therapy is an accurate knowledge of the interactions between the microclimate in warming therapy devices and the thermal balance of the infant. For generating this knowledge, thermal manikins can be helpful. Suitable models capable of also simulating evaporative heat loss in preterm infants have, however, not been available to date. A thermal manikin representing an infant weighing 530 g and capable of simulating convective, radiative and also evaporative heat loss has now been developed. It comprises an outer shell made of porous, anatomically shaped clay, and is divided into six compartments each of which can be heated individually. Water-filled Gore-Tex bags located immediately beneath the shell are provided to simulate evaporation. In a clinical study, temperature profiles of 8 very small preterm infants were measured thermographically. Measurements in the manikin showed that highly comparable temperature profiles with only minor differences could be obtained. Total heat and water losses by the manikin were in good agreement with clinical values. Using the model described here it is possible to simulate the heat exchange of premature infants under extreme and accurately reproducible environmental conditions. This manikin may thus serve as a tool for comparative studies, for the development of warming therapy equipment, or for training purposes. PMID:9616993

    Background Prolonged use of neuromuscular blocking agents (NMBAs) is very common in critically ill children both in pediatric and neonatal intensive care units. There are no guidelines available for use of NMBAs in children or neonates in the US, and the data for their safety in this age group is limited. Case Description Our case describes prolonged neuromuscular blockade following concurrent use of a NMBA along with aminoglycosides and steroids in the setting of renal failure in a premature infant. Conclusion Prolonged use of NMBAs in preterm infants should be avoided if possible or should be restricted to the shortest possible duration and the smallest possible physiologically effective dose. Concurrent use of NMBAs with aminoglycoside and steroids should be avoided, especially in the setting of renal failure. PMID:26495168

    In the weeks after birth, the gut acquires a nascent microbiome, and starts its transition to bacterial population equilibrium. This early-in-life microbial population quite likely influences later-in-life host biology. However, we know little about the governance of community development: does the gut serve as a passive incubator where the first organisms randomly encountered gain entry and predominate, or is there an orderly progression of members joining the community of bacteria? We used fine interval enumeration of microbes in stools from multiple subjects to answer this question. We demonstrate via 16S rRNA gene pyrosequencing of 922 specimens from 58 subjects that the gut microbiota of premature infants residing in a tightly controlled microbial environment progresses through a choreographed succession of bacterial classes from Bacilli to Gammaproteobacteria to Clostridia, interrupted by abrupt population changes. As infants approach 33-36 wk postconceptional age (corresponding to the third to the twelfth weeks of life depending on gestational age at birth), the gut is well colonized by anaerobes. Antibiotics, vaginal vs. Caesarian birth, diet, and age of the infants when sampled influence the pace, but not the sequence, of progression. Our results suggest that in infants in a microbiologically constrained ecosphere of a neonatal intensive care unit, gut bacterial communities have an overall nonrandom assembly that is punctuated by microbial population abruptions. The possibility that the pace of this assembly depends more on host biology (chiefly gestational age at birth) than identifiable exogenous factors warrants further consideration. PMID:25114261

    Premature infants often cannot successfully and coordinately complete their oral feeding. Mature sucking, swallowing, and respiration activities are crucial indicators for the survival of newborn infants. Due to the vulnerability and unobvious muscle activities of premature infants, current clinical care givers mainly depend on the subjective behavioral observation of infants during oral feeding. There is still lack of an integrated oral feeding monitoring system to objectively and quantifiably monitor the related physiological parameters of premature infants. In this study, a wireless multi-parameter monitoring system for oral feeding of premature infants was proposed to monitor the sucking-swallowing-respiratory activities and the heart rate variability to provide quantitative indices of oral feeding. Here, a novel sucking pressure sensing module was also developed to monitor the premature infant's sucking pressure under oral feeding to avoid the immersion influence of milk. The experimental results showed that the proposed system detected the related physiological parameters of premature infants during oral feeding effectively and may provide an objective clinical evaluation tool for oral feeding ability and safety of premature infants in the future.

    Although significant advances in the medical management of acutely ill preterm infants have resulted in unprecedented rates of survival, issues surrounding the convalescent care, discharge preparation, and readiness of parents or other caregivers have been less well studied and represent the art of medicine. Recent consensus statements provide a degree of content validity; however, important areas of scientific inquiry remain. Much is left to understand about the pathophysiology, management, and outcomes of apnea, bradycardia, and oxygen desaturation episodes continuing at term. Why do the most immature infants have a delay in the maturation of respiratory control? Do breathing studies really provide information that predicts subsequent respiratory control abnormalities? If methylxanthines are used at discharge, what criteria should be adhered to regarding their discontinuation? How is nutrition best provided while transitioning to home? In infants whose mothers desire exclusive breast-feeding, should gavage feeds be used to supplement in order to avoid bottle-feedings? How long should breast milk be fortified, and when should supplemented artificial milks be used and for what period of time postdischarge should these more expensive special-discharge artificial milks be used? What other supplements, such as inositol, vitamins, or antioxidants, should be provided in order to achieve optimal growth and development? Technology-dependent infants pose even greater complexities. Some infants and families adapt to extensive use of technology in the home. In other situations, basic infant care is difficult to achieve. What are the essential components for successful early discharge, and how can the studies involving selected families be made universal? How can NICUs better prepare fathers and mothers for premature parenthood? To what extent are we overwhelming families with additional responsibilities and expectations that may compromise their competency in basic parenting

    Objective To examine the effect of sildenafil therapy on development of severe retinopathy of prematurity (ROP) requiring surgical intervention in premature infants. Study Design We identified premature infants who were discharged from Pediatrix Medical Group neonatal intensive care units from 2003–2012 and who received an ophthalmologic exam. We matched each infant exposed to sildenafil prior to first eye exam to three non-exposed infants using propensity scoring to control for differences in baseline infant characteristics. We evaluated the association between sildenafil exposure and development of severe ROP using conditional logistic regression. Result Of the 57815 infants meeting inclusion criteria, 88 were exposed to sildenafil. We matched 81/88 (92%) sildenafil-exposed with 243 non-exposed infants. There was no difference in the proportion of infants who developed severe ROP in the sildenafil-exposed vs. non-exposed groups (17/81 [21%] vs. 38/243 [16%], P=0.27). On adjusted analysis, there was no difference in severe ROP in the sildenafil-exposed versus non-exposed infants (odds ratio=1.46, 95% confidence interval=0.76–2.82, P=0.26). Conclusion We did not observe an association between risk of severe ROP and sildenafil exposure prior to first eye exam in this cohort of premature infants. PMID:26491852

    We used a cost-effective, non-invasive method to obtain high-quality DNA from buccal epithelial-cells (BEC) of premature infants for genomic analysis. DNAs from BEC were obtained from premature infants with gestational age ≤ 36 weeks. Short terminal repeats (STRs) were performed simultaneously on DNA obtained from the buccal swabs and blood from the same patient. The STR profiles demonstrated that the samples originated from the same individual and exclude any contamination by external DNAs. Whole exome sequencing was performed on DNAs obtained from BEC on premature infants with and without necrotizing enterocolitis, and successfully provided a total number of reads and variants corroborating with those obtained from healthy blood donors. We provide a proof of concept that BEC is a reliable and preferable source of DNA for high-throughput sequencing in premature infants. PMID:24598548

While there has been much progress in understanding unique vulnerabilities of developing oligodendrocytes over the past 30 years, there remain no proven therapies for the premature infant beyond supportive care. The lack of translational progress may be partially explained by the challenge of developing relevant animal models when the etiology remains unclear, as is the case in this disorder. There has been an emphasis on hypoxia-ischemia and infection/inflammation as upstream etiologies, but less consideration of other contributory factors. This review highlights the evolution of white matter pathology in the premature infant, discusses the prevailing proposed etiologies, critically analyzes a sampling of common animal models and provides detailed support for our hypothesis that nutritional and hormonal deprivation may be additional factors playing critical and overlooked roles in white matter pathology in the premature infant.

    OBJECTIVE: to analyze the total Premature Infant Pain Profile scores of premature infants undergoing arterial puncture during music and 25% glucose interventions, and to assess their association with neonatal and therapeutic variables. METHOD: a randomized clinical trial with 80 premature infants; 24 in the Experimental Group 1 (music), 33 in the Experimental Group 2 (music and 25% glucose), 23 in the Positive Control Group (25% glucose). All premature infants were videotaped and a lullaby was played for ten minutes before puncture in Experimental Groups 1 and 2; 25% glucose administered in Experimental Group 2 and the Positive Control Group two minutes before puncture. RESULTS: 60.0% of premature infants had moderate or maximum pain; pain scores and intervention groups were not statistically significant. Statistically significant variables: Experimental Group 1: head and chest circumference, Apgar scores, corrected gestational age; Experimental Group 2: chest circumference, Apgar scores, oxygen therapy; Positive Control group: birth weight, head circumference. CONCLUSION: neonatal variables are associated with pain in premature infants. Brazilian Registry of Clinical Trials: UTN: U1111-1123-4821. PMID:25493677

    Premature infants requiring an ophthalmic examination or even surgery for retinopathy of prematurity (ROP) have a high prevalence of co-existing bronchopulmonary dysplasia (BPD). Reactive airway is one of the clinical presentations of BPD. We report two cases of bronchoconstriction following instillation of mydriatic eye drops. One occurred during induction of anesthesia for laser photocoagulation and the other before screening of ROP. The most likely cause in each case was phenylephrine eye drops. We recommend that the minimal dosage of phenylephrine needed to attain proper mydriasis should be instilled to infant patients, and the possibility of bronchoconstriction occurrence kept in mind, especially for infants with low body weight with BPD.

    Over the past 30 years, a variety of intervention programs for the enhancement of the neurodevelopmental status of premature infants have been implemented with confusing outcomes. In addition, diametrically different forms of therapy that rest on contrasting theories have led, paradoxically, to similar results. This article systematically examines and analyses the various modes of therapy and their underlying theoretical mechanisms. Skin-to-skin contact (kangaroo care) is suggested as the intervention that most logically meshes the premature infant's need to develop state regulation while facilitating sequential sensory development and promoting mother-infant attachment.

    2016-01-01

    Bone mineralization of preterm infants is significantly less than full-term infants at birth, placing preterm infants at risk for osteopenia of prematurity and other metabolic bone diseases. Advances in nutritional supplementation and standard nursing care alone have been unsuccessful in improving bone mineralization postnatally. Research supports a daily physical activity protocol of passive range of motion and gentle joint compression when combined with adequate nutritional supplementation reduces osteopenia of prematurity. This article provides a systematic review of the current evidence surrounding early physical activity and neonatal massage for the treatment of osteopenia and indicates the need for universal handling protocols in caring for this unique population.

    The aim of this study was to describe the experiences of being a father to a prematurely born infant. Eight fathers of prematurely born children were interviewed using a narrative approach, and a thematic content analysis was used to analyse the interviews. The fathers described that the preterm birth gave them the chance to get to know their infant as they had to spend time at the intensive care unit. They also felt better educated by professionals who helped them take care of their infant. Their feelings and attachment for their infant increased over time and the fathers felt that they had a stronger bond with their child compared with friends who had babies born at term. As time passed, they became more confident as a father. In spite of the strain, the experience made them change as a person and they expressed having different values. The relationship with their partner was strengthened as they handled this situation together as a couple. However, the fathers felt fortunate despite everything and described having managed a prematurely born infant rather well. Although there are similarities between being a father to a child born at term and to one born preterm, it is significant to gain further knowledge about the specific experiences of fathers of prematurely born infants. The results of this study have implications for nurses working with families who have children born prematurely. PMID:18269426

    Intraventricular hemorrhage (IVH) is a common, serious problem among premature infants. With advances in neonatal care, improved survival rates of small premature infants and improved diagnostic capabilities, IVH is seen with increased frequency in the high-risk nursery. Studies indicate 15-20% of premature infants (birth weight less than 1,500 gms), have been noted to have IVH Many of these neonates survive beyond infancy and may subsequently be seen in pediatric neurosurgery and neurology clinics with long-term problems such as hydrocephalus, cerebral palsy, mental retardation and seizures. Although long-term sequelae are not always present, it is beneficial for the neuroscience nurse to be able to understand the mechanisms of brain injury with IVH in order to anticipate long-term problems and provide comprehensive follow-up care for infants and children with this diagnosis.

  7. The effectiveness of video interaction guidance in parents of premature infants: A multicenter randomised controlled trial

    PubMed Central

    2012-01-01

    Background Studies have consistently found a high incidence of neonatal medical problems, premature births and low birth weights in abused and neglected children. One of the explanations proposed for the relation between neonatal problems and adverse parenting is a possible delay or disturbance in the bonding process between the parent and infant. This hypothesis suggests that due to neonatal problems, the development of an affectionate bond between the parent and the infant is impeded. The disruption of an optimal parent-infant bond -on its turn- may predispose to distorted parent-infant interactions and thus facilitate abusive or neglectful behaviours. Video Interaction Guidance (VIG) is expected to promote the bond between parents and newborns and is expected to diminish non-optimal parenting behaviour. Methods/design This study is a multi-center randomised controlled trial to evaluate the effectiveness of Video Interaction Guidance in parents of premature infants. In this study 210 newborn infants with their parents will be included: n = 70 healthy term infants (>37 weeks GA), n = 70 moderate term infants (32–37 weeks GA) which are recruited from maternity wards of 6 general hospitals and n = 70 extremely preterm infants or very low birth weight infants (<32 weeks GA) recruited by the NICU of 2 specialized hospitals. The participating families will be divided into 3 groups: a reference group (i.e. full term infants and their parents, receiving care as usual), a control group (i.e. premature infants and their parents, receiving care as usual) and an intervention group (i.e. premature infants and their parents, receiving VIG). The data will be collected during the first six months after birth using observations of parent-infant interactions, questionnaires and semi-structured interviews. Primary outcomes are the quality of parental bonding and parent-infant interactive behaviour. Parental secondary outcomes are (posttraumatic) stress symptoms

    Objective To analyze the process of care provided to premature infants in a neonatal intensive care unit and the factors associated with their mortality. Methods Cross-sectional retrospective study of premature infants in an intensive care unit between 2008 and 2010. The characteristics of the mothers and premature infants were described, and a bivariate analysis was performed on the following characteristics: the study period and the "death" outcome (hospital, neonatal and early) using Pearson's chi-square test, Fisher's exact test or a chi-square test for linear trends. Bivariate and multivariable logistic regression analyses were performed using a stepwise backward logistic regression method between the variables with p<0.20 and the "death" outcome. A p value <0.05 was considered to be significant. Results In total, 293 preterm infants were studied. Increased access to complementary tests (transfontanellar ultrasound and Doppler echocardiogram) and breastfeeding rates were indicators of improving care. Mortality was concentrated in the neonatal period, especially in the early neonatal period, and was associated with extreme prematurity, small size for gestational age and an Apgar score <7 at 5 minutes after birth. The late-onset sepsis was also associated with a greater chance of neonatal death, and antenatal corticosteroids were protective against neonatal and early deaths. Conclusions Although these results are comparable to previous findings regarding mortality among premature infants in Brazil, the study emphasizes the need to implement strategies that promote breastfeeding and reduce neonatal mortality and its early component.

    Introduction: Family, especially mother, is faced with numerous challenges by experiencing a premature birth. Since knowing about mother's efforts regarding prematurely born infant helps us in our comprehensive understanding of the impact of this incident on the family system and its performance. The present study was carried out to explore the mothers' strategies regarding prematurely born infant. Methods: In a conventional qualitative content analysis, data was collected through purposive sampling by semi-structured deep interviews with 18 mothers who had prematurely born infant during 2012-2013 in the teaching hospitals of the north and northwest of Iran. All the interviews were recorded, typed, and finally analyzed. Results: Data analysis resulted in the extraction of categories of "asking for help, elevating capacity and reducing personal responsibilities and commitments". These categories were revealed in mothers respectively by the different sub-categories of "religious appeal and relying on beliefs, seeking information from the treatment and caring team, participating in infant's care, companionship and support of family and friends","focusing on positive thinking and imagination, patience and strength " and "ignoring some routine affairs and reducing role-related activities and duties".Conclusion: Considering the uniqueness of the mother's role in responding to the needs of infants, healthcare system should consider mothers as real target in the intervention strategies in order to promote health and quality of life, so maybe this way, the burden of care and management of critical situations caused by a premature birth on the mother can be reduced.

    We determined the glycemic response to intravenous lipid infusion alone, lipid with amino acids, or amino acids alone in 15 very small premature infants receiving constant glucose infusion during early life. Infants who received lipid or lipid and amino acids demonstrated significant increases in glucose compared with infants who received amino acids. The combination of lipid and amino acids resulted in an earlier increase than lipid alone. Although plasma insulin did not change in all three groups, infants who received amino acids alone demonstrated an appropriate increase in glucagon. These data suggest that lipid infusion, a commonly used means of providing nutrition to premature infants, may cause significant disturbances in glucoregulation, particularly when administered with amino acids.

    An elevated serum phosphorus (P) has been anecdotally described in premature infants receiving human milk fortified with donor human milk-derived fortifier (HMDF). No studies have prospectively investigated serum P in premature infants receiving this fortification strategy. In this single center prospective observational cohort study, extremely premature infants ≤1250 grams (g) birth weight (BW) were fed an exclusive human milk-based diet receiving HMDF and serum P levels were obtained. We evaluated 93 infants with a mean gestational age of 27.5 ± 2.0 weeks (Mean ± SD) and BW of 904 ± 178 g. Seventeen infants (18.3%) had at least one high serum P level with a mean serum P of 9.2 ± 1.1 mg/dL occurring at 19 ± 11 days of life. For all infants, the highest serum P was inversely correlated to the day of life of the infant (p < 0.001, R2 = 0.175) and positively correlated with energy density of HMDF (p = 0.035). Serum P was not significantly related to gender, BW, gestational age, or days to full feeds. We conclude that the incidence of hyperphosphatemia was mild and transient in this population. The risk decreased with infant age and was unrelated to gender, BW, or ethnicity. PMID:25912036

    (1) Background: Assessing the quality of growth in premature infants is important in order to be able to provide them with optimal nutrition. The Pea Pod device, based on air displacement plethysmography, is able to assess body composition of infants. However, this method has not been sufficiently evaluated in premature infants; (2) Methods: In 14 infants in an age range of 3–7 days, born after 32–35 completed weeks of gestation, body weight, body volume, fat-free mass density (predicted by the Pea Pod software), and total body water (isotope dilution) were assessed. Reference estimates of fat-free mass density and body composition were obtained using a three-component model; (3) Results: Fat-free mass density values, predicted using Pea Pod, were biased but not significantly (p > 0.05) different from reference estimates. Body fat (%), assessed using Pea Pod, was not significantly different from reference estimates. The biological variability of fat-free mass density was 0.55% of the average value (1.0627 g/mL); (4) Conclusion: The results indicate that the Pea Pod system is accurate for groups of newborn, moderately premature infants. However, more studies where this system is used for premature infants are needed, and we provide suggestions regarding how to develop this area. PMID:27110820

    Background Human milk oligosaccharides (HMOs) shape the intestinal microbiota in term infants. In premature infants, alterations in the intestinal microbiota (dysbiosis) are associated with risk of necrotizing enterocolitis and sepsis and the influence of HMOs on the microbiota is unclear. Methods Milk, urine, and stool specimens from 14 mother-premature infant dyads were investigated by mass spectrometry for HMO composition. The stools were analyzed by next-generation sequencing (NGS) to complement a previous analysis. Results Percentages of fucosylated and sialylated HMOs were highly variable between individuals but similar in urine, feces and milk within dyads. Differences in urine and fecal HMO composition suggest variability in absorption. Secretor status of the mother correlated with the urine and fecal content of specific HMO structures. Trends toward higher levels of Proteobacteria and lower levels of Firmicutes, were noted in premature infants of non-secretor mothers. Specific HMO structures in the milk, urine and feces were associated with alterations in fecal Proteobacteria and Firmicutes. Conclusion HMOs may influence the intestinal microbiota in premature infants. Specific HMOs, for example those associated with secretor mothers, may have a protective effect by decreasing pathogens associated with sepsis and necrotizing enterocolitis while other HMOs may increase dysbiosis in this population.

    Premature birth is associated with high rates of motor and cognitive disability. Investigations have described resting-state functional magnetic resonance imaging (rs-fMRI) correlates of prematurity in older children, but comparable data in the neonatal period remain scarce. We studied 25 term-born control infants within the first week of life and 25 very preterm infants (born at gestational ages ranging from 23 to 29 weeks) without evident structural injury at term equivalent postmenstrual age. Conventional resting-state network (RSN) mapping revealed only modest differences between the term and prematurely born infants, in accordance with previous work. However, clear group differences were observed in quantitative analyses based on correlation and covariance matrices representing the functional MRI time series extracted from 31 regions of interest in 7 RSNs. In addition, the maximum likelihood dimensionality estimates of the group-averaged covariance matrices in the term and preterm infants were 5 and 3, respectively, indicating that prematurity leads to a reduction in the complexity of rs-fMRI covariance structure. These findings highlight the importance of quantitative analyses of rs-fMRI data and suggest a more sensitive method for delineating the effects of preterm birth in infants without evident structural injury.

    We aim to determine risk factors and clinical outcomes for bowel perforation in premature infants with NEC. We analyzed clinical data of 57 cases of premature infants with NEC at our NICU between January 2010 and December 2012. Based on the presence of bowel perforation, we divided these infants into two groups: perforated NEC group (n = 10) and nonperforated NEC group (n = 47). We compared general information, clinical characteristics, and laboratory findings between groups. The perforated NEC group, compared to the nonperforated NEC group, had significantly lesser gestational age, lower birth weight, higher prevalence of apnea, mechanical ventilation, sepsis and shock, lower blood pH, higher levels of blood glucose, abnormal WBC count and thrombocytopenia, and elevated CRP (all P < 0.05). Moreover, the perforated NEC group had significantly longer durations of fasting and TPN usage, higher incidences of EUGR and cholestasis, longer duration of antibiotics, higher frequency of advanced antibiotics use, and poorer prognosis than the nonperforated NEC group (all P < 0.05). Bowel perforation in premature infants with NEC was associated with multiple risk factors. Early identification of some of these risk factors in premature infants with NEC may help implement early intervention to reduce the incidence of bowel perforation and thereby improve the prognosis.

    The low-weight newborns and especially the premature infants have difficulty in maintaining their temperature in the range considered to be normal. Several studies revealed the importance of thermal environment and moisture to increase the survival rate of newborns. This work models the process of heat exchange and energy balance in premature newborns during the first hours of life in a closed incubator. In addition, a control problem was proposed and solved in order to maintain thermal stability of premature newborns to increase their rate of survival and weight. For this purpose, we propose an algorithm to control the temperature inside the incubator. It takes into account the measurements of the body temperature of a premature newborn which are recorded continuously. We show that using this model the temperature of a premature newborn inside the incubator can be kept in a thermal stability range. PMID:25557201

    Purpose: To report on subclinical retinal abnormalities shown through handheld spectral domain optical coherence tomography on a premature infant. Methods: Case report. Results: The initial and follow-up exams on a premature infant revealed severely attenuated ganglion cell and nerve fiber layers. There was cystoid macular edema in both eyes at the initial visits, which resolved by the 1-year follow-up. Discussion: Optical coherence tomography can reveal significant retinal abnormalities in premature infants which are not detectable through funduscopic exam. Documenting such findings may be useful for the comprehensive management of vision problems in children with a history of premature birth. PMID:26529438

    The usual route of acquisition for intrauterine herpes simplex virus (HSV) infection is transplacental. We evaluated a premature infant with in utero acquisition of HSV resulting from ascending infection.

    Premature infants are highly vulnerable to aberrant gastrointestinal tract colonization, a process that may lead to diseases like necrotizing enterocolitis. Thus, spread of potential pathogens among hospitalized infants is of great concern. Here, we reconstructed hundreds of high-quality genomes of microorganisms that colonized co-hospitalized premature infants, assessed their metabolic potential, and tracked them over time to evaluate bacterial strain dispersal among infants. We compared microbial communities in infants who did and did not develop necrotizing enterocolitis. Surprisingly, while potentially pathogenic bacteria of the same species colonized many infants, our genome-resolved analysis revealed that strains colonizing each baby were typically distinct. In particular, no strain was common to all infants who developed necrotizing enterocolitis. The paucity of shared gut colonizers suggests the existence of significant barriers to the spread of bacteria among infants. Importantly, we demonstrate that strain-resolved comprehensive community analysis can be accomplished on potentially medically relevant time scales.

    The authors studied the effects of different kinds of phototherapy in 186 newborns with a gestational age less than 33 weeks and weighing less than 2500 g. A control group of 60 infants was compared with a group of 31 infants submitted to photoprophylaxis, a group of 54 infants treated with day light, and a group of 41 infants treated with day light + special blue light. As far as the serum bilirubin variations in the first week, the maximum levels attained and the number of exchange transfusions are concerned, phototherapy always proved effective in reducing potentially neurotoxic serum bilirubin concentrations. Among the infants subjected to treatment, those treated with the day light showed a significant smaller decrease of serum bilirubin compared to those treated with the day light + special blue light, even if levels above 15 mg/dl were found in a similar percentage. Only 3.2% of the babies treated with photoprophylaxis showed serum bilirubin values above 15 mg/dl. The authors conclude that prophylaxis seems to be preferable to other phototherapeutic schedules used in the treatment of hyperbilirubinemia in low gestational age infants. PMID:3658802

    Background: Results of several studies suggest that prone position is beneficial in improving the preterm infants’ cardio-respiratory status. Previous studies showed opposite results, and also there is not any available clear study about the effect of this position on cardio-respiratory rates of Nasal Continuous Positive Airway Pressure (N-CPAP) treating premature infants. Objectives: This study aimed at comparing supine and prone positions on cardio-respiratory rates of premature infants with respiratory distress syndrome (RDS) who were treated using N-CPAP. Patients and Methods: This was a cross over study which was performed in 2010 on 44 hospitalized 29-34 weeks gestation premature infants who were receiving N-CPAP in Neonatal Intensive Care Unit of Al-Zahra Hospital of Tabriz University of Medical Sciences. Infants were randomly assigned into two groups, and the first group was placed in prone at first and then in supine, and the position of second group was at first supine and then prone. Infants’ Heart Rate (HR) and Respiratory Rate (RR) were assessed three times in each position for 30 minutes. The data was recorded in a data-collection form, and demographic data was analyzed using t test, Chi square and Fisher exact test. Also, repeated measurement ANOVA and Tukey post-hoc tests were used. Results: There was a significant difference in HR and RR of premature infants who were similar in gestational age and clinical condition and placed in two positions. Premature infants’ HR and RR became lower at prone position than supine in both groups. So it can be concluded that prone position could decrease infants HR and RR, but supine position might increase them (P < 0.05). Conclusion: Our findings support prone positioning for premature infants. Therefore, it is advisable to NICU staff that if there is no obstacle for changing the infant’s position, prone position in infants with respiratory complications during receiving N-CPAP in NICU can be useful

    Aim: Haemodynamically significant patent ductus arteriosus (hsPDA) is frequently observed in premature infants. This study was conducted to explore whether the blood BNP can be a valuable biomarker to assess the necessity of treatment for hsPDA in premature infants. Methods: Serial measurements of the blood BNP were performed during the first 5 days of life in premature infants with hsPDA (Group I) and those without hsPDA (Group N). The definition of the hsPDA was the PDA requiring treatment, such as indomethacin administration and/or surgical ligation. Results: Forty-six subjects were enrolled. Compared with Group N, Group I showed significantly higher level of blood BNP at postnatal 24–96 h and demonstrated the peak value at postnatal 24–48 h. With the ROC curve using the data at postnatal 24–48 h in Group I, we deduced the predictive value of 250 pg/mL of blood BNP for indomethacin treatment. Similarly, with the ROC curve using the maximal value of blood BNP within the first 5 days of life, the predictive value of 2000 pg/mL for surgical ligation was deduced. Conclusions: Blood BNP during early postnatal period can be a useful biomarker to assess the necessity of treatment for hsPDA in premature infants. PMID:23611593

    OBJECTIVE: Extremely low birth weight infants often require rehospitalization during infancy. Our objective was to identify at the time of discharge which extremely low birth weight infants are at higher risk for rehospitalization. METHODS: Data from extremely low birth weight infants in Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network centers from 2002–2005 were analyzed. The primary outcome was rehospitalization by the 18- to 22-month follow-up, and secondary outcome was rehospitalization for respiratory causes in the first year. Using variables and odds ratios identified by stepwise logistic regression, scoring systems were developed with scores proportional to odds ratios. Classification and regression-tree analysis was performed by recursive partitioning and automatic selection of optimal cutoff points of variables. RESULTS: A total of 3787 infants were evaluated (mean ± SD birth weight: 787 ± 136 g; gestational age: 26 ± 2 weeks; 48% male, 42% black). Forty-five percent of the infants were rehospitalized by 18 to 22 months; 14.7% were rehospitalized for respiratory causes in the first year. Both regression models (area under the curve: 0.63) and classification and regression-tree models (mean misclassification rate: 40%–42%) were moderately accurate. Predictors for the primary outcome by regression were shunt surgery for hydrocephalus, hospital stay of >120 days for pulmonary reasons, necrotizing enterocolitis stage II or higher or spontaneous gastrointestinal perforation, higher fraction of inspired oxygen at 36 weeks, and male gender. By classification and regression-tree analysis, infants with hospital stays of >120 days for pulmonary reasons had a 66% rehospitalization rate compared with 42% without such a stay. CONCLUSIONS: The scoring systems and classification and regression-tree analysis models identified infants at higher risk of rehospitalization and might assist planning for care after

    The neonatal intensive-care unit (NICU) environment may interfere with the maturation and organization of premature infants' central nervous systems and may fail to meet these infants' developmental needs. In particular, immature distance receptors (i.e., hearing and vision) may receive overwhelming stimulation, whereas more mature tactile and vestibular pathways receive little stimulation. Furthermore, research on fetal learning suggests that the NICU environment should sensitively address requirements for learning by providing contingent experience. Nurses are ideally suited to reorganize the NICU and intervene to optimize infants' growth and development. PMID:8083780

    Objective: To study the possibility of lower the nosocomial infection rate among the premature infants by prophylactic use of antibiotics. Methods: Retrospectively collect 409 premature infants admitted to the neonatal intensive care unit (NICU) of First Hospital of Jilin University between 1st January in 2009 and 31th December in 2011, who meet inclusion criteria. There were prohylactic group and nonprohylactic group randomly divided and compared the nosocomial infection rates of two groups. Results: The hospital infection rate of the prophylactic group was 62.9%, and the rate of the non-prophylactic group was 47.3%. There was a significant difference between the two groups (P<0.05). On the countrary, the prophylactic use of antibiotics could increase the incidence of the nosocomial infection. Conclusion: It does more harm than good that proghylactic use of antibiotics to prevent premature nosocomial infection. PMID:26629165

    Background Umbilical cord milking (UCM) improves blood pressure and urine output, and decreases the need for transfusions in comparison to immediate cord clamping (ICC). The immediate effect of UCM in the first few minutes of life and the impact on neonatal resuscitation has not been described. Methods Women admitted to a tertiary care center and delivering before 32 weeks gestation were randomized to receive UCM or ICC. A blinded analysis of physiologic data collected on the newborns in the delivery room was performed using a data acquisition system. Heart rate (HR), SpO2, mean airway pressure (MAP), and FiO2 in the delivery room were compared between infants receiving UCM and infants with ICC. Results 41 of 60 neonates who were enrolled and randomized had data from analog tracings at birth. 20 of these infants received UCM and 21 had ICC. Infants receiving UCM had higher heart rates and higher SpO2 over the first 5 minutes of life, were exposed to less FiO2 over the first 10 minutes of life than infants with ICC. Conclusions UCM when compared to ICC had decreased need for support immediately following delivery, and in situations where resuscitation interventions were needed immediately, UCM has the advantage of being completed in a very short time to improve stability following delivery.

    1992-01-01

    In a group of 6 premature infants, mean weight 1776 g, we measured skin surface temperatures, comparing infrared telethermography (San-ei Thermo-Tracer 6T62) and conventional skin thermometry (Eidatherm). Surface temperatures were measured at 10 different sites, with the infants nursed in an incubator. The same methods were used to compare temperatures on the lower arm of an adult. The results of the two different techniques showed only minor differences of approximately 0,2 degrees C. These discrepancies could be explained by problems of either method. They could also be attributed to the fact, that the emissivity of human skin is not exactly identical with the emissivity of a perfect black body. In clinical practice, infrared thermography and conductive thermometry can be used for determinations of body surface temperature of premature infants, also under the condition of high temperatures and high humidity within an incubator.

    Periventricular-intraventricular hemorrhage (PV-IVH) is a major cause of neurological disabilities in preterm newborns. This study aimed to determine the perinatal factors associated with PV-IVH. We conducted a retrospective case-control study from preterm infants born at ≤34 weeks of gestation and admitted to Neonatal Intensive Care Units of Seoul National University Children's Hospital and Seoul National University Bundang Hospital between June 2003 and December 2007. Neonates with no cranial sonographic data or infants transferred from other centers after three days of age were excluded. Of 1,044 eligible subjects, 59 infants with PV-IVH grade 2, 3, and 4 were allocated to the case group. The control group consisted of 118 infants without PV-IVH who were matched for gestational age and birth weight to each case of PV-IVH. At the multivariate logistic regression model, metabolic acidosis (odds ratio [OR]: 6.94; 95% confidence interval [CI]: 1.12-43.23) and use of inotropes (OR: 3.70; 95% CI: 1.16-11.84) were associated with an increased risk of PV-IVH. Maternal use of antenatal corticosteroids decreases the risk of PV-IVH (OR: 0.36; 95% CI: 0.14-0.92). PMID:20191041

    The continuous high-intensity noise in the neonatal intensive care unit (NICU) is both stressful and harmful for the premature infant. Although some researchers have found evidence that loud noise can cause hearing loss and alter physiologic and behavioral responses, no study to date has investigated the benefits of noise reduction by the use of earmuffs. In this study earmuffs were placed over the premature infants' ears to reduce noise intensity in the NICU while physiologic and behavioral responses were measured. Two sites were used to collect data: in the first setting, 17 low birth weight infants were randomly assigned to an experimental and a control group, whereas 13 infants from a second hospital acted as their own controls and were tested with and without earmuffs. Earmuffs that reduced the intensity of noise by 7 to 12 dB were worn by infants in the experimental group only during the observation periods. Infants in the control group were exposed to the usual noise in the NICU. The infant's physiologic and behavioral responses were observed for four 2-hour intervals, morning and evening, on two consecutive days. Most of the significant results were from the site at which infants acted as their own controls. When infants wore the earmuffs, they had significantly higher mean oxygen saturation levels and less fluctuation in oxygen saturation. Furthermore, these infants had less frequent behavioral state changes, spent more time in the quiet sleep state, and had longer bouts in the sleep state. It is imperative that NICUs develop aggressive antinoise policies to substantially and consistently reduce noise. PMID:8648453

    Fluconazole is an effective agent for prophylaxis of invasive candidiasis in premature infants. The objective of this study was to characterize the population pharmacokinetics (PK) and dosing requirements of fluconazole in infants with birth weights of <750 g. As part of a randomized clinical trial, infants born at <750 g birth weight received intravenous (i.v.) or oral fluconazole at 6 mg/kg of body weight twice weekly. Fluconazole plasma concentrations from samples obtained by either scheduled or scavenged sampling were measured using a liquid chromatography-tandem mass spectrometry assay. Population PK analysis was conducted using NONMEM 7.2. Population PK parameters were allometrically scaled by body weight. Covariates were evaluated by univariable screening followed by multivariable assessment. Fluconazole exposures were simulated in premature infants using the final PK model. A population PK model was developed from 141 infants using 604 plasma samples. Plasma fluconazole PK were best described by a one-compartment model with first-order elimination. Only serum creatinine was an independent predictor for clearance in the final model. The typical population parameter estimate for oral bioavailability in the final model was 99.5%. Scavenged samples did not bias the parameter estimates and were as informative as scheduled samples. Simulations indicated that the study dose maintained fluconazole troughs of >2,000 ng/ml in 80% of simulated infants at week 1 and 59% at week 4 of treatment. Developmental changes in fluconazole clearance are best predicted by serum creatinine in this population. A twice-weekly dose of 6 mg/kg achieves appropriate levels for prevention of invasive candidiasis in extremely premature infants. PMID:27401564

  20. Radiant energy and insensible water loss in the premature newborn infant nursed under a radiant warmer.

    1982-10-01

    Radiant warmers are a powerful and efficient source of heat serving to warm the cold-stressed infant acutely and to provide uninterrupted maintenance of body temperature despite a multiplicity of nursing, medical, and surgical procedures required to care for the critically ill premature newborn in today's intensive care nursery. A recognized side-effect of radiant warmer beds is the now well-documented increase in insensible water loss through evaporation from an infant's skin. Particularly the very-low-birth-weight, severely premature, and critically ill neonate is subject to this increase in evaporative water loss. The clinician caring for the infant is faced with the difficult problem of fluid and electrolyte balance, which requires vigilant monitoring of all parameters of fluid homeostasis. Compounding these difficulties, other portions of the electromagnetic spectrum (for example, phototherapy) may affect an infant's fluid metabolism by mechanisms that are not well understood. The role of plastic heat shielding in reducing large insensible losses in infants nursed on radiant warmer beds is currently under intense investigation. Apparently, convective air currents and not radiant heat energy may be the cause of the observed increase in insensible water loss in the intensive care nursery. A thin plastic blanket may be effective in reducing evaporative water loss by diminishing an infant's exposure to convective air currents while being nursed on an open radiant warmer bed. A rigid plastic body hood, although effective as a radiant heat shield, is not as effective in preventing exposure to convection in the intensive care nursery and, therefore, is not as effective as the thin plastic blanket in reducing insensible water loss. Care should be exercised in determining the effect of heat shielding on all parameters of heat exchange (convection, evaporation, and radiation) before application is made to the critically ill premature infant nursed on an open radiant

    Rationale Though treatment of the prematurely born infant breathing with assistance of a mechanical ventilator has much advanced in the past decades, predicting extubation outcome at a given point in time remains challenging. Numerous studies have been conducted to identify predictors for extubation outcome; however, the rate of infants failing extubation attempts has not declined. Objective To develop a decision-support tool for the prediction of extubation outcome in premature infants using a set of machine learning algorithms Methods A dataset assembled from 486 premature infants on mechanical ventilation was used to develop predictive models using machine learning algorithms such as artificial neural networks (ANN), support vector machine (SVM), naïve Bayesian classifier (NBC), boosted decision trees (BDT), and multivariable logistic regression (MLR). Performance of all models was evaluated using area under the curve (AUC). Results For some of the models (ANN, MLR and NBC) results were satisfactory (AUC: 0.63–0.76); however, two algorithms (SVM and BDT) showed poor performance with AUCs of ~0.5. Conclusion Clinician's predictions still outperform machine learning due to the complexity of the data and contextual information that may not be captured in clinical data used as input for the development of the machine learning algorithms. Inclusion of preprocessing steps in future studies may improve the performance of prediction models. PMID:25419493

    Premature birth has been associated with a number of adverse maternal psychological outcomes that include depression, anxiety, and trauma as well as adverse effects on maternal coping ability and parenting style. Infants and children who were premature are more likely to have poorer cognitive and developmental functioning and, thus, may be harder to parent. In response to these findings, there have been a number of educational and behavioral interventions developed that target maternal psychological functioning, parenting and aspects of the parent-infant relationship. Since the last comprehensive review of this topic in 2002, there have been a significant number of developments in the quality of the studies conducted and the theoretical models that address the experience of parents of premature infants. In the current review, eighteen new interventions were identified and grouped into four categories based on treatment length and the target of the intervention. Findings suggest a trend towards early, brief interventions that are theoretically based, specifically target parent trauma, and utilize cognitive behavioral techniques. Although it is difficult to generalize study findings, conclusions from the review suggest that targeted interventions may have positive effects on both maternal and infant outcomes. PMID:24532861

    2016-09-01

    Post-haemorrhagic hydrocephalus (PHH) is the most common neurological complication of preterm birth and can result in severe and life-long psychomotor and cognitive sequelae. Cerebrospinal fluid diversion is often required but the optimum time for intervention is unclear. Numerous neurosurgical procedures exist to temporise PHH but it is not clear which is the optimum method. Approximately 15% of preterm infants who suffer intraventricular haemorrhage (IVH) will require permanent cerebrospinal fluid diversion with a ventriculoperitoneal shunt. It is likely that earlier intervention may result in reduced neurological disability and ventriculoperitoneal shunt dependency. In this review we discuss the current methods of PHH management.

    Each year more than 250,000 infants in the United States are exposed to artificial lighting in hospital nurseries with little consideration given to environmental lighting cycles. Essential in determining whether environmental lighting cycles need to be considered in hospital nurseries is identifying when the infant’s endogenous circadian clock becomes responsive to light. Using a non-human primate model of the developing human, we examined when the circadian clock, located in the hypothalamic suprachiasmatic nuclei (SCN), becomes responsive to light. Preterm infant baboons of different ages were exposed to light (5,000 lux) at night, and then changes in SCN metabolic activity and gene expression were assessed. After exposure to bright light at night, robust increases in SCN metabolic activity and gene expression were seen at ages that were equivalent to human infants at 24 weeks after conception. These data provide direct evidence that the biological clock of very premature primate infants is responsive to light. PMID:10051658

    The purpose of the study was to present spectral-domain optical coherence tomography (OCT) findings in premature infants with or without mild-to-severe retinopathy of prematurity (ROP). Seventy-two infants born <37 weeks of gestation were analyzed, prospectively. Group 1 (n = 18) included infants without ROP. Infants with stage 1, 2, or 3 ROP without indication for treatment formed the second group (n = 15). Group 3 (n = 21) included threshold cases, who would receive laser photocoagulation (LPC) after OCT examinations. Group 4 (n = 18) had already received LPC. The mean central foveal thickness (CFT) (μm) in right eyes was 194.27 ± 19.93, 207.67 ± 25.44, 224.29 ± 21.42, and 222.00 ± 37.80, for groups 1, 2, 3, and 4, respectively (p = 0.01). The presence of a well-formed foveal pit was documented in 60 % of right and 67 % of left eyes in group 1, while a well-formed foveal pit was observed in 14 % of right and 16 % of left eyes in group 3 (p < 0.05). Cystoid macular edema (CME) was shown in 29 % of right and 21 % of left eyes in group 3 (p < 0.05 for right eyes). CME was observed in two of right and left eyes in group 4. Epiretinal membrane (ERM) was shown in one right eye in group 3, two right and four left eyes in group 4 (p < 0.05 for left eyes). Thicker CFT, CME, and failure of a well-formed foveal pit could be related to the severity of ROP. The development of ERM could be the consequence of LPC. PMID:26750097

    Objectives: Early nutrition influences metabolic programming and long-term health. We explored the urinary metabolite profiles of 48 premature infants (birth weight < 1500 g) randomized to an enhanced or a standard diet during neonatal hospitalization. Methods: Metabolomics using nuclear magnetic resonance spectroscopy (NMR) was conducted on urine samples obtained during the first week of life and thereafter fortnightly. Results: The intervention group received significantly higher amounts of energy, protein, lipids, vitamin A, arachidonic acid and docosahexaenoic acid as compared to the control group. Enhanced nutrition did not appear to affect the urine profiles to an extent exceeding individual variation. However, in all infants the glucogenic amino acids glycine, threonine, hydroxyproline and tyrosine increased substantially during the early postnatal period, along with metabolites of the tricarboxylic acid cycle (succinate, oxoglutarate, fumarate and citrate). The metabolite changes correlated with postmenstrual age. Moreover, we observed elevated threonine and glycine levels in first-week urine samples of the small for gestational age (SGA; birth weight < 10th percentile for gestational age) as compared to the appropriate for gestational age infants. Conclusion: This first nutri-metabolomics study in premature infants demonstrates that the physiological adaptation during the fetal-postnatal transition as well as maturation influences metabolism during the breastfeeding period. Elevated glycine and threonine levels were found in the first week urine samples of the SGA infants and emerged as potential biomarkers of an altered metabolic phenotype. PMID:24824288

    Background The current study assessed whether contrast sensitivity is affected in preterm infants with a history of spontaneously regressed retinopathy of prematurity (ROP, Stages 1–3). Specifically, we employed luminance (light/dark) and chromatic (red/green) stimuli, which are mediated by the magnocellular (M) and parvocellular (P) subcortical pathways, respectively. Methods Contrast sensitivity (CS) was measured using forced choice preferential looking testing in 21 infants with a history of ROP and 41 control preterm infants who were born prematurely but did not develop ROP, tested between 8 and 47 weeks (2–11 months) postterm age. Infants were presented with chromatic and luminance drifting sinusoidal gratings, which appeared randomly on the left or right side of the monitor on each trial. The contrast of the stimuli varied across trials and was defined in terms of root mean squared cone contrast for long- and medium-wavelength cones. Results Between 8 and 25 weeks postterm, ROP infants had significantly worse CS, and there was a trend for greater impairment for Luminance than Chromatic CS. This delay was not seen at older ages between 26 and 47 weeks postterm. Conclusions These findings are consistent with the concept that early maturation of the M pathway is vulnerable to biological insult, as in the case of ROP, to a greater extent than is the P pathway.

    Summary Bronchopulmonary Dysplasia (BPD) is a rare chronic lung disease and one of the most difficult complications to treat in premature infants. With the progress at the medical treatment level, an increasing number of BPD premature infants are born, meanwhile, they would be at an increasing risk for numerous complications and rehospitalization because BPD affects many vital organ systems. The pathogenesis of BPD is clearly multifactorial. As the prognosis is closely connected with the severity of BPD, early diagnosis and treatment are of great help to control the development of BPD. This article focuses on risk factors that could influence the severity of BPD in order to provide a reliable basis for early diagnosis, treatment, and better patient assessment. PMID:25984426

    As part of a study of thyroid function in premature babies, the iodine content of their mothers' breast milk, that of 32 formulas from different brands used in Spain, and that of 127 formulas used in other countries was determined. Breast milk contained more iodine--mean (SEM) 10 (1) microgram/dl--than most of the formulas, especially those for premature babies. Iodine intakes were therefore below the recommended daily amount (RDA) for newborns: babies of 27-30 weeks' gestational age took 3.1 (1.1) micrograms/day at 5 days of age and 29.8 (2.7) micrograms by 2 months of age. This problem is not exclusive to Spanish premature babies as the iodine content of many of the formulas on sale in other countries was also inadequate. It is concluded that preterm infants who are formula fed are at high risk of iodine deficiency. PMID:7820714

    As part of a study of thyroid function in premature babies, the iodine content of their mothers' breast milk, that of 32 formulas from different brands used in Spain, and that of 127 formulas used in other countries was determined. Breast milk contained more iodine--mean (SEM) 10 (1) microgram/dl--than most of the formulas, especially those for premature babies. Iodine intakes were therefore below the recommended daily amount (RDA) for newborns: babies of 27-30 weeks' gestational age took 3.1 (1.1) micrograms/day at 5 days of age and 29.8 (2.7) micrograms by 2 months of age. This problem is not exclusive to Spanish premature babies as the iodine content of many of the formulas on sale in other countries was also inadequate. It is concluded that preterm infants who are formula fed are at high risk of iodine deficiency. PMID:7820714

    We conducted a prospective cohort study in four hospitals in Lima, Peru in infants with a birth weight ≤ 1,500 g followed from birth hospital discharge up to 1 year of age to determine the incidence of respiratory syncytial virus (RSV) hospitalizations. We enrolled 222 infants from March of 2009 to March of 2010: 48 infants with a birth weight < 1,000 g and 174 infants with a birth weight of 1,000–1,500 g (birth weight = 1,197 ± 224 g; gestational age = 30.1 ± 2.6 weeks). There were 936 episodes of respiratory infections; the incidence of respiratory infections during the first 1 year of life was 5.7 episodes/child-years. The incidence of RSV respiratory infections that required emergency room management was 103.9 per 1,000 child-years, and the incidence of RSV hospitalizations was 116.2 per 1,000 child-years (244.9 in infants with a birth weight < 1,000 g and 88.9 in infants 1,000–1,500 g; P < 0.05). The incidence of RSV respiratory infections that required emergency management or hospitalization is high among pre-mature infants in Lima. PMID:25294617

    An apparatus to calibrate the system of measuring O2 consumption and CO2 production has been developed for premature infants. This system is based on the alcohol combustion principal. The alcohol combustion is used to test the indirect calorimetric system due to its simplicity and reliability. In the previous studies, the O2 consumption rate of alcoholic combustion is too large to simulate the breath of premature infants. A new design is proposed to burn alcohol continuously at a rate as low as 0.004 ml min-1, equivalent to an O2 consumption rate of only 3.9 ml min-1, a level in the breath range of preterms of about 660 g based on the measurement 5.9 ml kg-1 min-1. The alcohol combusts with various steady-state rates to imitate the breath of premature infants, and it is useful for a canopy open-circuit system. The calibration tool proposed here would be helpful in the clinical study of energy expenditure for preterms.

    Randomized trials of oxygen saturation target ranges for extremely preterm infants showed increased survival but increased retinopathy of prematurity with higher compared with lower target ranges. In our center, changing from a target range of 88%-92% to 91%-95% has been associated with increased rates and severity of retinopathy of prematurity. PMID:26548746

    Objective: Endotracheal intubation is a common procedure in neonatal care. The objective of this study was to determine whether the premedication with remifentanil before intubation has analgesic effects in newborn infants. Methods: A total of 40 premature infants who needed endotracheal intubation for intubation-surfactant-extubation method were randomly assigned in two groups of an equal number at two university hospitals. The control group was given 10 μg/kg atropine IV infusions in 1 min and then 2 ml normal saline. In the case group, the atropine was given with the same method and then remifentanil was administered 2 μg/kg IV infusions in 2 min. Findings: For remifentanil and control groups, the mean birth weight were 1761 ± 64 and 1447 ± 63 grams (P = 0.29), and the mean gestational ages were 31.69 ± 3.5 and 30.56 ± 2.8 weeks (P = 0.28), respectively. Using premature infant pain profile score, infants who received remifentanil felt significantly less pain than the control group (15.1 ± 1.6 vs. 7.5 ± 1.4; P < 0.001). There were no significant differences in the duration of endotracheal intubation procedure (20.8 ± 6 vs. 22.8 ± 7.3 s; P = 0.33), the number of attempts for successful intubation and oxygen desaturation between groups. Conclusion: Premedication with remifentanil has good analgesic effects for endotracheal intubation in premature infants without significant derangements in mean blood pressure and oxygen saturation.

    In this retrospective case series, we report the spectrum and outcomes of aggressive posterior retinopathy of prematurity (APROP) in infants ≥ 1500 g birth weight. Twenty-nine eyes of 15 infants are included. All infants were referred from level I or II nurseries, received supplemental unmonitored oxygen for prolonged duration (>1 week) and had multiple systemic co-morbidities. Of the 29 eyes, 10 (34.5%) had zone 1 and 19 (65.5%) had posterior zone 2 disease. Twenty-five (86.2%) eyes had flat neovascularization and 4 (13.8%) eyes had brush like proliferation. We noticed large vascular loops in 10 (34.5%) eyes. After confluent laser photocoagulation, 22 (75.9%) eyes had a favorable outcome. The study concludes that APROP in heavier (≥ 1500 g birth weight) premature infants occurs mostly in posterior zone 2 with flat neovascularization and atypical features like large vascular loops. Supplemental unmonitored oxygen for prolonged duration and multiple systemic co-morbidities could be a contributing factor. PMID:24618495

    Autonomic nervous system (ANS) balance is a key factor in homeostatic control of cardiac activity, breathing and certain reflex reactions such as coughing, sneezing and swallowing and thus plays a crucial role for survival. ANS impairment has been related to many neonatal pathologies, including sudden infant death syndrome (SIDS). Moreover, some conditions have been identified as risk factors for SIDS, such as prone sleep position. There is an urgent need for timely and non-invasive assessment of ANS function in at-risk infants. Systematic measurement of heart rate variability (HRV) offers an optimal approach to access indirectly both sympathetic and parasympathetic influences on ANS functioning. In this paper, data from premature infants collected in a sleep physiology laboratory in the NICU are presented: traditional and novel approaches to HRV analyses are applied and compared in order to evaluate their relative merits in the assessment of ANS activity and the influence of sleep position. Indices from time domain and nonlinear approaches contributed as markers of physiological development in premature infants. Moreover, significant differences were observed as a function of sleep position. PMID:27480495

    IMPORTANCE Invasive candidiasis in premature infants causes mortality and neurodevelopmental impairment. Fluconazole prophylaxis reduces candidiasis, but its effect on mortality and the safety of fluconazole is unknown. OBJECTIVE To evaluate the efficacy and safety of fluconazole in preventing death or invasive candidiasis in extremely low-birth-weight infants. DESIGN, SETTING, AND PATIENTS This study was a randomized, blinded, placebo-controlled trial of fluconazole in premature infants. Infants weighing less than 750 g at birth (N = 361) from 32 neonatal intensive care units (NICUs) in the United States were randomly assigned to receive either fluconazole or placebo twice weekly for 42 days. Surviving infants were evaluated at 18 to 22 months corrected age for neurodevelopmental outcomes. The study was conducted between November 2008 and February 2013. INTERVENTIONS Fluconazole (6 mg/kg of body weight) or placebo. MAIN OUTCOMES AND MEASURES The primary end point was a composite of death or definite or probable invasive candidiasis prior to study day 49 (1 week after completion of study drug). Secondary and safety outcomes included invasive candidiasis, liver function, bacterial infection, length of stay, intracranial hemorrhage, periventricular leukomalacia, chronic lung disease, patent ductus arteriosus requiring surgery, retinopathy of prematurity requiring surgery, necrotizing enterocolitis, spontaneous intestinal perforation, and neurodevelopmental outcomes—defined as a Bayley-III cognition composite score of less than 70, blindness, deafness, or cerebral palsy at 18–22-months corrected age. RESULTS Among infants receiving fluconazole, the composite primary end point of death or invasive candidiasis was 16% (95% CI, 11%–22%) vs 21% in the placebo group (95% CI, 15%–28%; odds ratio 0.73 [95% CI 0.43–1.23]; P=.24; treatment difference −5% [95% CI, −13%–3%]). Invasive candidiasis occurred less frequently in the fluconazole group (3% [95% CI, 1%

    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.

    The cerebral white matter is vulnerable to injury in very preterm infants (born prior to 30 weeks gestation), resulting in a spectrum of lesions. These range from severe forms, including cystic periventricular leukomalacia and periventricular hemorrhagic infarction, to minor focal punctate lesions. Moderate to severe white matter injury in preterm infants has been shown to predict later neurodevelopmental disability, although outcomes can vary widely in infants with qualitatively comparable lesions. Resting state functional connectivity magnetic resonance imaging has been increasingly utilized in neurodevelopmental investigations and may provide complementary information regarding the impact of white matter injury on the developing brain. We performed resting state functional connectivity magnetic resonance imaging at term equivalent postmenstrual age in fourteen preterm infants with moderate to severe white matter injury secondary to periventricular hemorrhagic infarction. In these subjects, resting state networks were identifiable throughout the brain. Patterns of aberrant functional connectivity were observed and depended upon injury severity. Comparisons were performed against data obtained from prematurely-born infants with mild white matter injury and healthy, term-born infants and demonstrated group differences. These results reveal structural-functional correlates of preterm white matter injury and carry implications for future investigations of neurodevelopmental disability. PMID:23874510

    In the premature infant, somatosensory and visual stimuli trigger an immature electroencephalographic (EEG) pattern, “delta-brushes,” in the corresponding sensory cortical areas. Whether auditory stimuli evoke delta-brushes in the premature auditory cortex has not been reported. Here, responses to auditory stimuli were studied in 46 premature infants without neurologic risk aged 31 to 38 postmenstrual weeks (PMW) during routine EEG recording. Stimuli consisted of either low-volume technogenic “clicks” near the background noise level of the neonatal care unit, or a human voice at conversational sound level. Stimuli were administrated pseudo-randomly during quiet and active sleep. In another protocol, the cortical response to a composite stimulus (“click” and voice) was manually triggered during EEG hypoactive periods of quiet sleep. Cortical responses were analyzed by event detection, power frequency analysis and stimulus locked averaging. Before 34 PMW, both voice and “click” stimuli evoked cortical responses with similar frequency-power topographic characteristics, namely a temporal negative slow-wave and rapid oscillations similar to spontaneous delta-brushes. Responses to composite stimuli also showed a maximal frequency-power increase in temporal areas before 35 PMW. From 34 PMW the topography of responses in quiet sleep was different for “click” and voice stimuli: responses to “clicks” became diffuse but responses to voice remained limited to temporal areas. After the age of 35 PMW auditory evoked delta-brushes progressively disappeared and were replaced by a low amplitude response in the same location. Our data show that auditory stimuli mimicking ambient sounds efficiently evoke delta-brushes in temporal areas in the premature infant before 35 PMW. Along with findings in other sensory modalities (visual and somatosensory), these findings suggest that sensory driven delta-brushes represent a ubiquitous feature of the human sensory

    The care of premature infants in the 20th century is remarkable for technical advances that have dramatically improved survival, but little is known about temporal changes in the neuropathology of the premature infant over this time frame. We hypothesize that the autopsy rate of germinal matrix hemorrhage changed in the 20th century relative to combined influences of clinical interventions that were both harmful and helpful. We examined germinal matrix hemorrhage with intraventricular hemorrhage (GMH-IVH) in 345 premature infants (gestational age 25-36 weeks) autopsied at Boston Children's Hospital from 1914 to 2015. There was a median of 19 cases/decade (range 7-68). Over the course of the study median gestational age decreased from 33 to 27 gestational weeks (P<0.001), and median postnatal survival increased from 2 to 26 days (P=0.02). The incidence of GMH-IVH increased from 4.7% before 1960 to 50.0% from 1975 to 1980, and then decreased to 12.5% after 2005 (P<0.001). The incidence of GMH-IVH increased >3-fold around the time of the introduction of positive pressure ventilation into premature intensive care in the mid-1960s. The increased incidence of GMH-IVH in the 1970s-1980s likely reflects respiratory and hemodynamic imbalances complicating mechanical ventilation. We speculate that the subsequent decreased incidence of GMH-IVH likely reflects stabilization of respiratory function with improvements in ventilators and in ventilator management beginning in the 1970s and the use of surfactant and antenatal steroids in the 1980s.

    Background: A study was undertaken to determine the impact of respiratory syncytial virus (RSV) infection, both in hospital and the community, on healthcare utilisation and respiratory morbidity in prematurely born infants and to identify risk factors for symptomatic RSV infection. Methods: A hospital and community follow up study was undertaken of 126 infants born before 32 weeks of gestational age. Healthcare utilisation (hospital admissions and general practitioner attendances) in the first year, respiratory morbidity at follow up (wheeze and cough documented by parent completed diary cards), and RSV positive lower respiratory tract infections (LRTIs) were documented. Nasopharyngeal aspirates were obtained for immunofluorescence and culture for RSV whenever the infants had an LRTI, either in the community or in hospital. Results: Forty two infants had an RSV positive LRTI (RSV group), 50 had an RSV negative LRTI (RSV negative LRTI group), and 32 infants had no LRTI (no LRTI group). Compared with the RSV negative LRTI and the no LRTI groups, the RSV group required more admissions (p = 0.392, p<0.001) and days in hospital (p = 0.049, p = 0.006) and had more cough (p = 0.05, p = 0.038) and wheeze (p = 0.003, p = 0.003) at follow up. Significant risk factors for symptomatic RSV LRTI were number of siblings (p = 0.035) and maternal smoking in pregnancy (p = 0.005), for cough were number of siblings (p = 0.002) and RSV LRTI (p = 0.02), and for wheeze was RSV LRTI (p = 0.019). Conclusion: RSV infection, even if hospital admission is not required, is associated with increased subsequent respiratory morbidity in prematurely born infants. PMID:16227330

    Background Late-onset bloodstream infection (LO-BSI) is a common complication of prematurity, and lack of timely diagnosis and treatment can have life-threatening consequences. We sought to identify clinical characteristics and microbial signatures in the gastrointestinal microbiota preceding diagnosis of LO-BSI in premature infants. Method Daily faecal samples and clinical data were collected over two years from 369 premature neonates (<32 weeks gestation). We analysed samples from 22 neonates who developed LO-BSI and 44 matched control infants. Next-generation sequencing of 16S rRNA gene regions amplified by PCR from total faecal DNA was used to characterise the microbiota of faecal samples preceding diagnosis from infants with LO-BSI and controls. Culture of selected samples was undertaken, and bacterial isolates identified using MALDI-TOF. Antibiograms from bloodstream and faecal isolates were compared to explore strain similarity. Results From the week prior to diagnosis, infants with LO-BSI had higher proportions of faecal aerobes/facultative anaerobes compared to controls. Risk factors for LO-BSI were identified by multivariate analysis. Enterobacteriaceal sepsis was associated with antecedent multiple lines, low birth weight and a faecal microbiota with prominent Enterobacteriaceae. Staphylococcal sepsis was associated with Staphylococcus OTU faecal over-abundance, and the number of days prior to diagnosis of mechanical ventilation and of the presence of centrally-placed lines. In 12 cases, the antibiogram of the bloodstream isolate matched that of a component of the faecal microbiota in the sample collected closest to diagnosis. Conclusions The gastrointestinal tract is an important reservoir for LO-BSI organisms, pathogens translocating across the epithelial barrier. LO-BSI is associated with an aberrant microbiota, with abundant staphylococci and Enterobacteriaceae and a failure to mature towards predominance of obligate anaerobes. PMID:26167683

    Hemodynamically significant ductus arteriosus (hsPDA) may alter organ perfusion by interfering blood flow to the tissues. Therefore, in infants with hsPDA, hypoxia occurs in many tissues. In this study, we aimed to investigate the diagnostic significance of serum (ischemia-modified albumin) IMA levels as a screening tool for hsPDA, and its relation to the severity of the disease in the preterm neonates. For this purpose, seventy-two premature infants with gestation age <34 weeks were included in the study. Thirty premature infants with hsPDA were assigned as the study group and 42 premature infants without PDA were determined as the control group. Blood samples were collected before the treatment and 24 h after the treatment, and analyzed for IMA levels. IMA levels in the study group (1.26 ± 0.36 ABSU) were found to be significantly higher than control group (0.65 ± 0.12 ABSU) (p < 0.05). In infants with hsPDA, a positive correlation was found between IMA and PDA diameter (ρ = 0.876, p = 0.022), and LA/Ao ratio (ρ = 0.863, p = 0.014). The cut-off value of IMA for hsPDA was measured as 0.78 ABSU with 88.89 % sensitivity, and 90.24 % specificity, 85.71 % positive predictive, 92.5 % negative predictive value [area under the curve (AUC) = 0.96; p < 0.001]. The mean IMA value of the infants with hsPDA before treatment was 1.26 ± 0.36 ABSU, and the mean IMA value of infants after medical treatment was 0.67 ± 0.27 ABSU (p = 0.03). We concluded that IMA can be used as a marker for the diagnosis and monitoring of a successful treatment of hsPDA. PMID:27069332

    The purpose of this study was to learn the reason why mothers remain at the hospital throughout the stay of their premature infant at the Neonatal Intensive Care Unit. The study was performed with twelve mothers to premature newborns at a municipal maternity hospital in Rio de Janeiro, in 2007. The methodological support used in the study was the Sociological Phenomenology of Alfred Schütz. The phenomenological interview was used to capture the mothers' discourse, whose intentional action was unveiled through the following categories: Taking care of the child--dealing with the challenge of having a small baby; Staying near the premature child--the mother's presence helps the child's recovery to be faster; Reciprocal help among mothers--reinforcing hope every day. Rooming-in care stands out as an innovative and relevant initiative during the hospital stay of preterm infants, and it is considered an environment for living together, sharing experiences, and giving mutual support throughout the long and difficult stay at the hospital.

    Purpose: To report the impact of transient, self-resolving, untreated “macular edema” detected on spectral domain optical coherence tomography in Asian Indian premature infants with retinopathy of prematurity (ROP) on visual acuity (VA) and refraction at 1-year of corrected age. Materials and Methods: Visual acuity and refraction of 11 infants with bilateral macular edema (Group A) was compared with gestational age-matched 16 infants with ROP without edema (Group B) and 17 preterms infants without ROP and without edema (Group C) at 3, 6, 9 and 12 months of corrected age using Teller Acuity Cards and cycloplegic retinoscopy. Sub-group analysis of the previously described pattern A and B macular edema was performed. Results: Visual acuity was lower in infants with macular edema compared with the other two control groups throughout the study period, but statistically significant only at 3 months. Visual improvement in these infants was highest between the 3rd and 6th month and plateaued by the end of the 1st year with acuity comparable to the other two groups. The edema cohort was more hyperopic compared to the other two groups between 3 and 12 months of age. Pattern A edema had worse VA compared to pattern B, although not statistically significant. Conclusion: Macular edema, although transient, caused reduced VA as early as 3 months of corrected age in Asian Indian premature infants weighing <2000 g at birth. The higher hyperopia in these infants is possibly due to visual disturbances caused at a critical time of fovealization. We hypothesize a recovery and feedback mechanism based on the principles of active emmetropization to explain our findings. PMID:26139806

    Retinopathy of prematurity (ROP) continues to be an important cause of potentially preventable blindness worldwide. The pattern of visual impairment from ROP in some middle-income countries--high rates affecting larger and more mature infants--resembles that seen in more developed countries two decades ago and has been called a "third epidemic" of the disease. Expert bodies in the United Kingdom and the United States have recently issued new guidelines for screening for ROP that utilize both birth weight and gestational age criteria. Studies in both countries suggest these criteria might be further revised to decrease time spent on screening without missing any significant disease. Population-based follow-up studies of extremely preterm infants suggest that although more preterm infants are surviving, with adequate screening and treatment, rates of blindness from ROP may be declining. Further information on the longer-term impact of ROP comes from a number of studies and particularly the Multicenter Trial of Cryotherapy for Retinopathy of Prematurity (CRYO-ROP) study. The risk of both myopia and strabismus is increased with any and each higher stage of ROP. Evidence is emerging that laser therapy for threshold disease may be associated with better visual outcome than cryotherapy, although complications following the former remain a concern. The fight against ROP may be enhanced by new information on the pathogenesis, including possible genetic predisposition and the role of vascular endothelial growth factor. PMID:10537772

    The objective of the study is to determine whether salivary FOXP2 gene expression levels at the initiation of oral feeding attempts are predictive of oral feeding success in the premature newborn. In this prospective study, saliva samples from 21 premature infants (13 males; birth gestational age [GA]: 30–34 wk) were collected around the initiation of oral feeding trials. Total RNA was extracted and underwent reverse transcription-quantitative polymerase chain reaction amplification for FOXP2. Oral feeding success was denoted by the days required to attain full oral feeds. A linear regression model, controlling for sex, birth GA, and weight at salivary collection, revealed that FOXP2 expression was significantly associated with oral feeding success (P = 0.002). The higher the expression level of FOXP2, the shorter the duration to feed. Salivary FOXP2 expression levels are significantly associated with oral feeding success in the preterm infant. FOXP2 may serve as a novel and informative biomarker to noninvasively assess infant feeding skills to reduce morbidities and length of stay. PMID:27148579

    The clinical details are reported of two premature infants who developed late onset haemorrhagic disease after receiving their initial doses of vitamin K1 prophylaxis intravenously. Both reported infants had received two doses of intravenous vitamin K1, 0.1 mg, in the 1st week of life, and a further oral dose, 1.0 mg, at 4 weeks. Bleeding due to vitamin K deficiency occurred on days 74 and 84, respectively. Vitamin K deficiency bleeding is rare in low birthweight infants, probably because it has been routine practice to give such infants intramuscular vitamin K1. One of the reported infants had cytomegalovirus hepatitis, the other did not have liver disease. These findings could be explained if intramuscular vitamin K1 were to have a longer duration of effect than intravenous vitamin K1. This may be because intramuscular vitamin K1 acts as a depot preparation. The findings suggest that intravenous vitamin K1 is less effective than intramuscular for long-term prophylaxis against late onset haemorrhagic disease. Intravenous vitamin K1 should not be used for long-term prophylaxis in the prevention of late onset haemorrhagic disease. PMID:8827551

    Although gains have been made in premature birth rates among racial and ethnic minority and low socioeconomic status populations, tremendous disparities still exist in both prematurity rates and health outcomes for preterm infants. Parental involvement is known to improve health outcomes for preterm babies. However, a gap in evidence exists around whether parental involvement can help ameliorate the disparities in both short- and long-term out-comes for their preterm children. Families more likely to experience preterm birth are also less likely to have access to paid leave and thus experience significant systemic barriers to involvement, especially when their newborns are hospitalized. This article describes the research gap in this area and explores pathways by which social workers may ameliorate disparities in preterm birth outcomes through practice, policy, and research.

    The purpose of this study was to examine the effect of music therapy intervention on premature infants' and full term infants' developmental responses and parents' responsiveness. Subjects (n=56) were parent-infant dyads who attended developmental music groups or a control condition assessing responsiveness during toy play. All subjects were matched according to developmental age and were also matched by group for socioeconomic status and for maternal depression. Types of infant play and parent responsiveness were measured using observation of a standardized toy play for parent-infant dyads. Observations were coded with the number of seconds spent in each behavior using the SCRIBE observation program. Parents completed a questionnaire on the perception of their infant's general development, interpretations of their child's needs, the purpose of using music with their child, and their child's response to music. The infants attending the developmental music groups with their parents demonstrated significantly more social toy play (p < .05) during the standardized parent-infant toy play than infants who did not attend the music groups. While not significant, graphic analysis of parent responsiveness showed parents who attended the developmental music groups engaged in more positive and less negative play behaviors with their infants than parents who did not attend the music groups. This study demonstrates the first findings of positive effects of developmental music groups on social behaviors for both premature and full term infants under 2 years old. PMID:19256731

    We present an infant who was born premature at 23 weeks gestation with bronchopulmonary dysplasia and a SFTPC gene mutation, p.R167Q, who had a complicated neonatal course requiring 4 months of mechanical ventilation. Over time, his clinical course has improved, and he only requires oxygen by nasal cannula and low dose hydroxychloroquine, suggesting that p.R167Q mutation contributed to his clinical course and may manifest with a variable disease pattern making long-term prognostication difficult in the immediate newborn period.

    A fatal case of transfusion-associated graft-versus-host disease developed in a premature infant after receiving several blood products, including nonirradiated white blood cells. Transfusion-associated graft-versus-host disease can be prevented. Irradiation of blood products is the least controversial and most effective method. Treatment was unsuccessful in most reported cases of transfusion-associated graft-versus-host disease. Therefore irradiation of blood products before transfusing to patients susceptible to transfusion-associated graft-versus-host disease is strongly recommended.

    This study demonstrates that infants who are born prematurely and who have experienced at least 40days of intensive or special care have increased brain neuronal responses to noxious stimuli compared to healthy newborns at the same postmenstrual age. We have measured evoked potentials generated by noxious clinically-essential heel lances in infants born at term (8 infants; born 37-40weeks) and in infants born prematurely (7 infants; born 24-32weeks) who had reached the same postmenstrual age (mean age at time of heel lance 39.2+/-1.2weeks). These noxious-evoked potentials are clearly distinguishable from shorter latency potentials evoked by non-noxious tactile sensory stimulation. While the shorter latency touch potentials are not dependent on the age of the infant at birth, the noxious-evoked potentials are significantly larger in prematurely-born infants. This enhancement is not associated with specific brain lesions but reflects a functional change in pain processing in the brain that is likely to underlie previously reported changes in pain sensitivity in older ex-preterm children. Our ability to quantify and measure experience-dependent changes in infant cortical pain processing will allow us to develop a more rational approach to pain management in neonatal intensive care.

    We report an infant with tetralogy of fallot (TOF) who was born at 35 weeks of gestation and of 1700 g birth weight and presented with persistent retinopathy of prematurity (ROP) at 6 months of age. Follow-up ophthalmic examinations were done at 2, 3, and 4 weeks of age. A demarcation line in Zone II was noticed on the first ocular examination done at 4 weeks of postnatal age. At 6 months of postnatal age, the infant still had an avascular peripheral retina with the demarcation line in Zone II. Even though this index subject did not have any typical risk factors for ROP, TOF seems to be the probable reason for developing as well as persistence of avascular retina. PMID:27525147

    Parents may experience profound stress when their infant is extremely premature or has exceptionally low birth weight. This article presents several approaches that clinicians and ethics consultants can use to reduce this stress when a parent is single and alone, as well as when both parents are present. Offering parents additional options, taking preventative measures, and using approaches based on recent innovations in psychotherapies are emphasized. Since the clinicians who care for these neonates may find it exceptionally stressful and may experience "burn out," especially over time, this article also addresses what may work best for them. Finally it will discuss clinicians, who, despite their best efforts, find that caring for these infants is simply too painful to bear. PMID:26399669

    A comparison was carried out between a series of neonates who weighed less than 1500 g at birth and received red cell transfusions for symptomatic anaemia of prematurity (group 1, n = 14) and controls of similar gestational age and weight, who remained well and were not transfused during their nursery stay (group 2, n = 10). Mean (SD) haemoglobin concentrations at birth were 163 (12) g/l and 183 (17) g/l (p = 0.004), respectively. Transfusion resulted in significantly better weight gain in six infants who had been growing poorly:mean (SE) 8.8 (2.8) g/day improved to 23.3 (2.1) g/day (p less than 0.002). Geometric mean (SD) serum immunoreactive erythropoietin (SiEp) concentrations (17.7 (1.3) U/l) for the whole group of infants were similar to those of normal adults (17.4 (4.7) U/l) despite considerably reduced haemoglobin values. There was a significant inverse correlation between haemoglobin and log SiEp concentrations in the infants requiring transfusion (r = -0.43; p less than 0.01), but this was not apparent in the untransfused babies. Moreover, at haemoglobin concentrations below 120 g/l the mean (SE) SiEp concentration of 20 (1.08) U/l in group 1 was significantly higher than in group 2 (14 (1.06) U/l; p = 0.002). These data suggest that an increased concentration of SiEp early in the course of the anaemia of prematurity helps to identify those infants who would benefit from red cell transfusions, but that clinical criteria, although ill defined, do so equally well.

    This paper describes a whole-body counter (WBC) specially designed to measured total body potassium (TBK) infants under 4500 g. The counter is a ''shadow shield'' design and consists of a single 10 cm X 10 cm X 45 cm NaI(Tl) crystal, positioned lengthwise and shielded from environmental background radiation by a minimum of 10 cm of lead. The standard error of counting for a 2000-s counting period is 19.9% for a 1000-g infant and 11.9% for a 2000-g infant. TBK of stillborn pigs, measured by the WBC, agreed to an average of 3% of TBK determined by carcass analysis in the same animals. A total of 118 measurements of TBK have been made in 50 premature infants ranging in weight between 1100 and 3600 g and in age between 2 and 75 days. The observed relationship of TBK with weight is described by the equation: TBK (mEq) = 0.0433Wt (g + 1.57 r = 0.92. Potassium retention per gram weight gain is estimated to be 0.043 mEq. The obtained TBK values agree well with values published by other workers but extend the range of measurement to 1100 g.

    Objective This study aims to determine the association between hyperglycemia, insulin therapy, and severe retinopathy of prematurity (ROP) in extremely low-birth-weight (ELBW) infants. Study Design In this retrospective database study, we included all ELBW infants who were ≤ 32 weeks gestational age (GA). We excluded infants without any ophthalmology evaluation and infants who died before 28 days of life. A multivariable model was constructed to determine the association between hyperglycemia, insulin use, and severe ROP. We defined hyperglycemia as blood glucose (BG) > 180 mg/dL. Covariates were GA, small for GA status, discharge year, sex, Apgar score at 5 minutes, mechanical ventilation, oxygen use, bacteremia, and postnatal steroid exposure. We defined severe ROP as ROP requiring bevacizumab, cryotherapy, laser therapy, or vitrectomy. Sensitivity analysis using BG > 150 mg/dL and > 200 mg/dL was performed. Results A total of 24,548 infants were included; 2,547 (10%) had severe ROP. Hyperglycemia alone was not associated with severe ROP (odds ratio [OR], 0.88; 95% confidence interval [CI], 0.66-1.17). Hyperglycemia and insulin use were not associated with severe ROP (OR, 1.43; 95% CI, 0.91-2.23). BG > 150 mg/dL and insulin use were associated with severe ROP (OR, 1.34; 95% CI, 1.02-1.76). Conclusions Hyperglycemia alone was not associated with severe ROP in ELBW infants. However, we did observe a possible trend between the use of insulin and severe ROP. PMID:26485249

    Neuroimaging studies indicate reduced volumes of certain gray matter regions in survivors of prematurity with periventricular leukomalacia (PVL). We hypothesized that subacute and/or chronic gray matter lesions are increased in incidence and severity in PVL cases compared to non-PVL cases at autopsy. Forty-one cases of premature infants were divided based on cerebral white matter histology: PVL (n = 17) with cerebral white matter gliosis and focal periventricular necrosis; diffuse white matter gliosis (DWMG) (n = 17) without necrosis; and “ Negative” group (n = 7) with no abnormalities. Neuronal loss was found almost exclusively in PVL, with significantly increased incidence and severity in the thalamus (38%), globus pallidus (33%), and cerebellar dentate nucleus (29%) compared to DWMG cases. The incidence of gliosis was significantly increased in PVL compared to DWMG cases in the deep gray nuclei (thalamus/basal ganglia; 50–60% of PVL cases), and basis pontis (100% of PVL cases). Thalamic and basal ganglionic lesions occur almost exclusively in infants with PVL. Gray matter lesions occur in a third or more of PVL cases suggesting that white matter injury generally does not occur in isolation, and that the term “perinatal panencephalopathy” may better describe the scope of the neuropathology.

    To investigate the regulation of end-expiratory lung volume (EEV) in premature infants, we recorded airflow, tidal volume, diaphragm electromyogram (EMG), and chest wall displacement during sleep. In quiet sleep, EEV during breathing was 10.8 +/- 3.6 (SD) ml greater than the minimum volume reached during unobstructed apneas. In active sleep, no decrease in EEV was observed during 28 of 35 unobstructed apneas. Breaths during quiet sleep had a variable extent of expiratory airflow retardation (braking), and inspiratory interruption occurred at substantial expiratory flow rates. During active sleep, the expiratory flow-volume curve was nearly linear, proceeding nearly to the volume axis at zero flow, and diaphragm EMG activity terminated near the peak of mechanical inspiration. Expiratory duration (TE) and inspiratory duration (TI) were significantly shortened in quiet sleep vs. active sleep although tidal volume was not significantly different. In quiet sleep, diaphragmatic braking activity and shortened TE combined to maintain EEV during breathing substantially above relaxation volume. In active sleep, reduced expiratory braking and prolongation of TE resulted in an EEV that was close to relaxation volume. We conclude that breathing strategy to regulate EEV in premature infants appears to be strongly influenced by sleep state. PMID:3571069

    Background and Aim: The postpartum period is a critical then effects on the structure of the family. Most women in the postpartum period may place at risk of undesirable experiences such as changes in sleep patterns. Therefore, this study aimed to identify the efficacy of the relaxation program on sleep quality of mothers with premature infants. Materials and Methods: This study is a clinical trial that 60 mothers with premature infants. The mothers in the intervention group were trained for muscle progressive relaxation by Jacobson method within 24–72 h after delivery. Research tool was the Pittsburgh Sleep Quality Index, which was completed by the mother at the beginning of the study, end of the first and the second 4-week. Data were analyzed using parametric statistics tests by SPSS software version 16. Results: No significant difference was observed between two groups in terms of underlying characteristics (P < 0.05). The independent t-test at the beginning of the study showed that the comparison of the mean scores of mothers’ sleep quality has no significant difference between two groups (P = 0.43). But, 1-month after the intervention (P = 0.024) and 2 months after the intervention (P > 0.001), mean sleep quality score in the intervention group was significantly less than the control group. Conclusion: Relaxation training can improve mothers’ sleep quality at postpartum period. PMID:27462639

    Because nervous system development may be affected by prematurity, many prematurely born children present language or cognitive disorders at school age. The goal of this study is to investigate whether these impairments can be identified early in life using electrophysiological auditory event-related potentials (AERPs) and mismatch negativity (MMN). Brain responses to speech and non-speech stimuli were assessed in prematurely born children to identify early electrophysiological markers of language and cognitive impairments. Participants were 74 children (41 full-term, 33 preterm) aged 3, 12, and 36 months. Pre-attentional auditory responses (MMN and AERPs) were assessed using an oddball paradigm, with speech and non-speech stimuli presented in counterbalanced order between participants. Language and cognitive development were assessed using the Bayley Scale of Infant Development, Third Edition (BSID-III). Results show that preterms as young as 3 months old had delayed MMN response to speech stimuli compared to full-terms. A significant negative correlation was also found between MMN latency to speech sounds and the BSID-III expressive language subscale. However, no significant differences between full-terms and preterms were found for the MMN to non-speech stimuli, suggesting preserved pre-attentional auditory discrimination abilities in these children. Identification of early electrophysiological markers for delayed language development could facilitate timely interventions. PMID:26476371

    Objective To analyse the association in newborns between blood levels of phenylalanine and feeding method and gestational age. Study Design This observational, cross-sectional study included a sample of 11,829 infants between 2008 and 2013 in a Spanish region. Data were recorded on phenylalanine values, feeding method [breast, formula, mixed (breast plus formula), or partial or fully intravenous feeding], gestational age in weeks (<32, 32–37, ≥37), gender and days since birth at the moment of blood collection. Outcomes were [phenylalanine] and [phenylalanine] ≥95th percentile. Associations were analysed using multivariate models [linear (means difference) and logistic regression (adjusted odds ratios)]. Results Higher phenylalanine values were associated with lower gestational age (p<0.001) and with intravenous feeding (p<0.001). Conclusion The degree of prematurity and intravenous feeding influenced the plasma concentration of phenylalanine in the newborn. Caution should be taken in [phenylalanine] for newborns with intravenous feeding, monitoring them carefully. Very preterm infants given the recommended amount of amino acids should also be strictly monitored. These findings should be taken into consideration and call for adapting the amounts to the needs of the infant. PMID:26389596

    AIM To describe the clinical characteristics and late results of patients with retinopathy of prematurity (ROP) treated with “6h cryotherapy”. METHODS Out of 1252 infants screened for ROP, 52 patients were treated with temporal 6h cryotherapy from 1997 to 2005 were recalled to our clinic. Among these 23 patients were available and 46 eyes of 23 infants were included to evaluate for visual acuity, refractive error, ocular alignment, nystagmus, retinal examination (abnormal branching of retinal vessels, retinal thinning, latis degenerations, tortuosity of vessels, straightening of temporal vessels, narrowing of the angle of vessel in the juxtapapillary entrance, pigment changes, macular heterotopia), optic atrophy and optic disc cupping, axial length at birth and axial length at 1y. RESULTS The median age at examination was 7 (5-18)y. In 32.6% of patients, the visual acuity was ≤20/200 and the mean best corrected visual acuity was 20/35 as measured with a Snellen chart. Mean spherical refractive error was -1.76±2.69 D. The degree of myopia at the last examination was found to be correlated with the elongation of the eye in the first year of life. Exotropia was present in 17.4% (n=8) of infants and esotropia in 13% (n=6). The most common retinal abnormality was abnormal branching of retinal vessels (82.6%) followed by retinal thinning (52.2%). CONCLUSION The late clinical outcomes of infants with ROP treated in our clinic with cryotherapy seems to comparable with results of laser treatment. PMID:27162730

    Background D-Lactate is normally present in the blood of humans at nanomolar concentrations due to methylglyoxal metabolism; millimolar D-lactate concentrations can arise due to excess gastrointestinal microbial production. Objectives To examine the levels of plasma D-lactate in the necrotizing enterocolitis in premature infants. Patients and Methods 128 premature infants were divided into control (group I, n = 69), feeding intolerance (group II, n = 42) and NEC (group III, n = 27) groups. Plasma D-lactate levels were measured at the onset of feeding intolerance or NEC and at weeks 2-3 in control infants (group I) by ELISA. Data were analyzed using descriptive statistics, non-parametric tests and Student’s t-test. Results In groups I, II, III, median birth weights were 1845.7 ± 267.5 g, 1913.1 ± 306.5 g, and 1898.4 ± 285.3 g, median gestational ages were 34.3 ± 1.7 weeks, 33.9 ± 2.2 weeks and 35.1 ± 2.6 weeks, ages of sampling were 12.3 ± 2.9 days, 14.6 ± 3.7 days and 15.1 ± 1.8 days, respectively. The differences of median birth weights, median gestational ages and ages of sampling were not statistically significant (P > 0.05). The plasma D-lactate levels in groups I, II, III were 3.6 ± 1.9 μg/mL, 12.7 ± 8.3 μg/mL, and 35.4 ± 29.1 μg/mL, respectively, group III had higher plasma D-lactate level than groups I, II, and the difference among these groups was significant (x2 = 21.6, P < 0.01). Conclusions Plasma D-lactate significantly increased early in NEC. Plasma D-lactate levels were associated with extensive disease in NEC infants. Therefore, it could be used as a diagnosis indicator in the early stage of NEC. PMID:27307969

    Aplasia cutis congenita (ACC) is usually located on the hairy scalp, on the vertex of the head, but can also occur in other locations, such as limbs, trunk. Congenital skin aplasia on the lower limb is very rare disorder. The exact etiopathogenesis is not known, but intrauterine conditions play a role in its development. ACC visually resembles an ulceration, with a smooth pink surface, which in most cases heals spontaneously. Depending on the wound size and whether signs of inflammation are present, the lesion may require local treatment. In the described case, surgical treatment was carried out because of the extreme prematurity of the infant. The outcome was satisfactory, causing no adverse impact on the child's development during the infancy. PMID:25420905

    We previously compared infant outcomes between a powdered human milk fortifier (P-HMF) vs. acidified liquid HMF (AL-HMF). A non-acidified liquid HMF (NAL-HMF) is now commercially available. The purpose of this study is to compare growth and outcomes of premature infants receiving P-HMF, AL-HMF or NAL-HMF. An Institutional Review Board (IRB) approved retrospective chart review compared infant outcomes (born < 2000 g) who received one of three HMF. Growth, enteral nutrition, laboratory and demographic data were compared. 120 infants were included (P-HMF = 46, AL-HMF = 23, NAL-HMF = 51). AL-HMF infants grew slower in g/day (median 23.66 vs. P-HMF 31.27, NAL-HMF 31.74 (p < 0.05)) and in g/kg/day, median 10.59 vs. 15.37, 14.03 (p < 0.0001). AL-HMF vs. NAL-HMF infants were smaller at 36 weeks gestational age (median 2046 vs. 2404 g, p < 0.05). However AL-HMF infants received more daily calories (p = 0.21) and protein (p < 0.0001), mean 129 cal/kg, 4.2 g protein/kg vs. P-HMF 117 cal/kg, 3.7 g protein/kg , NAL-HMF 120 cal/kg, 4.0 g protein/kg. AL-HMF infants exhibited lower carbon dioxide levels after day of life 14 and 30 (p < 0.0001, p = 0.0038). Three AL-HMF infants (13%) developed necrotizing enterocolitis (NEC) vs. no infants in the remaining groups (p = 0.0056). A NAL-HMF is the most optimal choice for premature human milk-fed infants in a high acuity neonatal intensive care unit (NICU). PMID:27472359

    We previously compared infant outcomes between a powdered human milk fortifier (P-HMF) vs. acidified liquid HMF (AL-HMF). A non-acidified liquid HMF (NAL-HMF) is now commercially available. The purpose of this study is to compare growth and outcomes of premature infants receiving P-HMF, AL-HMF or NAL-HMF.

    2014-01-01

    Background The source inoculum of gastrointestinal tract (GIT) microbes is largely influenced by delivery mode in full-term infants, but these influences may be decoupled in very low birth weight (VLBW, <1,500 g) neonates via conventional broad-spectrum antibiotic treatment. We hypothesize the built environment (BE), specifically room surfaces frequently touched by humans, is a predominant source of colonizing microbes in the gut of premature VLBW infants. Here, we present the first matched fecal-BE time series analysis of two preterm VLBW neonates housed in a neonatal intensive care unit (NICU) over the first month of life. Results Fresh fecal samples were collected every 3 days and metagenomes sequenced on an Illumina HiSeq2000 device. For each fecal sample, approximately 33 swabs were collected from each NICU room from 6 specified areas: sink, feeding and intubation tubing, hands of healthcare providers and parents, general surfaces, and nurse station electronics (keyboard, mouse, and cell phone). Swabs were processed using a recently developed ‘expectation maximization iterative reconstruction of genes from the environment’ (EMIRGE) amplicon pipeline in which full-length 16S rRNA amplicons were sheared and sequenced using an Illumina platform, and short reads reassembled into full-length genes. Over 24,000 full-length 16S rRNA sequences were produced, generating an average of approximately 12,000 operational taxonomic units (OTUs) (clustered at 97% nucleotide identity) per room-infant pair. Dominant gut taxa, including Staphylococcus epidermidis, Klebsiella pneumoniae, Bacteroides fragilis, and Escherichia coli, were widely distributed throughout the room environment with many gut colonizers detected in more than half of samples. Reconstructed genomes from infant gut colonizers revealed a suite of genes that confer resistance to antibiotics (for example, tetracycline, fluoroquinolone, and aminoglycoside) and sterilizing agents, which likely offer a

    Purpose. To determine genetic variants associated with severe retinopathy of prematurity (ROP) in a candidate gene cohort study of US preterm infants. Methods. Preterm infants in the discovery cohort were enrolled through the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network, and those in the replication cohort were from the University of Iowa. All infants were phenotyped for ROP severity. Because of differences in the durations of enrollment between cohorts, severe ROP was defined as threshold disease in the discovery cohort and as threshold disease or type 1 ROP in the replication cohort. Whole genome amplified DNA from stored blood spot samples from the Neonatal Research Network biorepository was genotyped using an Illumina GoldenGate platform for candidate gene single nucleotide polymorphisms (SNPs) involving angiogenic, developmental, inflammatory, and oxidative pathways. Three analyses were performed to determine significant epidemiologic variables and SNPs associated with levels of ROP severity. Analyses controlled for multiple comparisons, ancestral eigenvalues, family relatedness, and significant epidemiologic variables. Single nucleotide polymorphisms significantly associated with ROP severity from the discovery cohort were analyzed in the replication cohort and in meta-analysis. Results. Eight hundred seventeen infants in the discovery cohort and 543 in the replication cohort were analyzed. Severe ROP occurred in 126 infants in the discovery and in 14 in the replication cohort. In both cohorts, ventilation days and seizure occurrence were associated with severe ROP. After controlling for significant factors and multiple comparisons, two intronic SNPs in the gene BDNF (rs7934165 and rs2049046, P < 3.1 × 10−5) were associated with severe ROP in the discovery cohort and were not associated with severe ROP in the replication cohort. However, when the cohorts were analyzed together in an exploratory

    OBJECTIVE Advances in neonatal care have resulted in children born pre-maturely with respiratory distress syndrome (RDS) successfully reaching school age. It is unknown how many will be ready for school and what factors affect school readiness in these children at high risk. Our objective was to assess readiness of children born prematurely with RDS in the last decade for entry into public school, and determine risk factors associated with lack of school readiness in this population. METHODS This was a single-center prospective cohort study. Follow-up data were collected for 135 of 167 (81%) surviving premature infants with RDS requiring surfactant-replacement therapy and mechanical ventilation. The children were seen between July 2005 and September 2006 (average age: 5.7 ± 1.0 years) and underwent standardized neurodevelopmental and health assessments and socioeconomic status classification. A 4-level school-readiness score was constructed by using each child’s standardized scores on assessments of basic concepts (Bracken School-Readiness Assessment), perceptual skills (Visual-Motor Integration Test), receptive vocabulary (Peabody Picture Vocabulary Test, Third Edition), daily living functional skills (Pediatric Functional Independence Measure), and presence of sensory impairments or autism. Proportional odds models were used to identify risk factors predicting lower school-readiness levels. RESULTS Of the children examined, the mean birth weight was 1016 ± 391 g, and the mean gestational age was 27.5 ± 2.6 weeks. Ninety-one (67%) children were school-ready. Using multivariate analysis, male gender, chronic lung disease, and severe intraventricular hemorrhage or periventricular leukomalacia were associated with lower school-readiness levels. However, the most powerful factor determining school-readiness level was low socioeconomic status. CONCLUSION Interventions targeting neonatal morbidities may be much less effective at improving overall performance at

    Objective To examine whether premature infants receiving the maternally administered H-HOPE intervention had more rapid weight gain and growth, improved feeding progression, and reduced length of hospital stay, compared to controls. Study Design Premature infants born at 29–34 GA and their mothers with at least 2 social-environmental risk factors, were randomly assigned to H-HOPE intervention (n = 88) or an attention control (n = 94) groups. H-HOPE consists of a 15-minute multisensory intervention (auditory, tactile, visual and vestibular stimuli) performed twice daily prior to feeding plus maternal participatory guidance on preterm infant behavioral cues. Results H-HOPE group infants gained weight more rapidly over time than infants in the control group and grew in length more rapidly than control infants, especially during the latter part of the hospital stay. Conclusions For healthy preterm infants, the H-HOPE intervention appears to improve weight gain and length over time from birth to hospital discharge. PMID:25742287

    Airway injury may occur during the use of any instrumentation in premature infants. A surgical approach for the treatment of lung perforation in extremely low-birth-weight infants has been recommended in the past. Here, we present a case of lung perforation in an ex-28-week, 730-g premature infant, who sustained lung perforation, secondary to an 8-Fr suction catheter used to administer surfactant, in which the broken catheter was retained in the airway. Following removal of catheter by endoscopy, tension pneumothorax had occurred. Attempts were made to treat the patient with single chest tube, unfortunately as it was not efficacious, the second one was placed on the ipsilateral side of hemithorax and the patient recovered without further surgery.

    Research in pediatrics has led to marked improvements in survival in pediatric patients. In no other age group have these improvements been more dramatic than in neonatology, where antenatal steroid administration to mothers and postnatal utilization of surfactant have led to marked improvements in survival so that infants born at 24 weeks gestation now have a greater than 50% chance of survival. Unfortunately, more than 50% of these patients develop significant complications of prematurity with potential long-term impact on the health of these infants. Therefore, additional research must be done in these patients to prevent these complications or reduce the impact of these complications. There are many practical and some ethical issues that could impede research in the area. Interventional studies have succeeded because literally decades of research defined unequivocally the pathophysiology of diseases such as surfactant deficiency in RDS. Unfortunately, the pathophysiology leading to the complications of prematurity has been extrapolated from old concepts without verification as the population has become smaller and more premature than the previous era. Thus, an extremely important practical issue in pediatric research is whether to design interventions to address the extrapolated pathophysiology risking misinterpretations of the results of such studies. Or should our efforts be focused on defining endpoints associated with the development of diseases and complications which may define pathophysiology more completely but delay the design of interventions to improve the outcomes of patients. Another crucial practical issue in pediatric research is how to power studies so that interventions can be studied adequately. In the US, large neonatal networks have been formed so that large databases can be created and large multi-center trials can be performed. The practical issues associated with these network studies is the center to center variability in patient care

    An analysis of Oregon Vital Statistics data from 1965 to 1975 was conducted to assess the impact of Oregon's 1969 abortion legislation, which substantially increased the number of reported medically induced abortions. This increase was associated with a slight increase in the age-adjusted 1970 fertility rate and there was no decrease in births to women in the age groups obtaining proportionately the most abortions. A significant and persistent 11 per cent reduction in premature births to women over age 20 (p less than .001) and a 22 per cent reduction in spontaneous fetal deaths (p less than .05) were associated with liberalized abortion. Decreases in neonatal and postneonatal infant mortality were observed, but were indistinguishable from an ongoing trend toward improved infant health. A gradual 25 per cent decline in the age-adjusted fertility rate occurred between 1969 and 1975, but the increase in the number of reported abortions could account for only one-fourth of this decrease. A seven-fold increase in the use of family planning clinics between 1970 and 1973 and more liberalized laws regarding provision of family planning service appeared to account for a much higher proportion of the decreased fertility than did liberalized abortion.

    Reducing blood loss and the need for blood transfusions in extremely preterm infants is part of effective care. Delayed cord clamping is well supported by the evidence and is recommended for infants who do not immediately require resuscitation. Cord milking may be an alternative to delayed cord clamping; however, more research is needed to support its use. In view of concerns regarding the increased risk for cognitive delay, clinicians should avoid using hemoglobin transfusion thresholds lower than those tested in clinical trials. Higher transfusion volumes (15 mL/kg to 20 mL/kg) may decrease exposure to multiple donors. Erythropoietin is not recommended for routine use due to concerns about retinopathy of prematurity. Elemental iron supplementation (2 mg/kg/day to 3 mg/kg/day once full oral feeds are achieved) is recommended to prevent later iron deficiency anemia. Noninvasive monitoring (eg, for carbon dioxide, bilirubin) and point-of-care testing reduce the need for blood sampling. Clinicians should strive to order the minimal amount of blood sampling required for safe patient care, and cluster samplings to avoid unnecessary skin breaks. PMID:26744559

    Many women whose premature infants are hospitalized in a newborn intensive care unit choose to express breast milk for their babies. Yet anxiety, fatigue, and emotional stress are powerful inhibitors of lactation. To facilitate the breast-feeding experience, intervention mothers were given a 20-minute audio cassette tape based on relaxation and visual imagery techniques. At a single follow-up expression of milk at the hospital approximately 1 week after enrollment, they expressed 63% more breast milk than a randomized group of control mothers. The fat content of the breast milk in the two groups was not significantly different. Among a small group of mothers whose infants were receiving mechanical ventilation, the increase in milk volume compared with that of control mothers was 121%. Longer-term effects of the relaxation/imagery approach (such as extending the duration of breast-feeding or reducing parental stress after hospital discharge) and the physiologic basis for the increased volume of expressed milk (improved milk production v more efficient milk ejection) are appropriate topics for future research.

    The objective of this study is to determine the incidence and risk factors of retinopathy of prematurity (ROP) in extremely low birth weight (ELBW) Chinese infants. A retrospective medical record review of all ELBW (≤1,000 g) neonates screened for ROP from 2007 to 2012 was performed in Hong Kong. ROP screening was conducted at 2 neonatal intensive care units by 3 pediatric ophthalmologists using the Royal College of Ophthalmologists ROP guideline and the International Classification of ROP. Maternal and neonatal covariates were analyzed using univariate and multivariate regression analyses for both ROP and Type 1 ROP. In 131 ELBW Chinese infants, the mean gestational age (GA) and birth weight (BW) were 27.3 ± 3.3 weeks and 806.9 ± 133.7 g, respectively. The incidence of ROP and Type 1 ROP was 53.4 and 14.5 %, respectively. For ROP, a lighter BW, smaller GA, vaginal delivery, postnatal hypotension, inotrope use, bronchopulmonary dysplasia, surfactant use, invasive mechanical ventilation, and supplementary oxygen were independent risk factors for ROP, while PET was protective (P ≤ 0.02). On multivariate analysis, a smaller GA was a risk factor, while PET and congenital heart disease were protective for ROP development (P ≤ 0.01). For Type 1 ROP, a lighter BW, smaller GA, surfactant use, and invasive mechanical ventilation were independent risk factors for ROP, while PET was protective (P ≤ 0.02). There were no significant covariates on multivariate analysis for Type 1 ROP. In ELBW, preterm Chinese infants, a smaller GA was a risk factor for ROP, while PET and congenital heart disease were protective for ROP development in multivariate analysis. PMID:24898774

    Objectives This current study has been conducted to clarify the relationship between the mother's post-traumatic reaction triggered by premature birth and the mother-infant interactions. In this article, the precocious maternal feelings are described. Methods A multicenter prospective study was performed in three French hospitals. 100 dyads with 100 very premature infants and their mothers were recruited. Mothers completed, at two different times self-questionnaires of depression/anxiety, trauma and social support. The quality of interactions in the dyads was evaluated. Results Thirty-nine percent of the mothers obtained a score at HADS suggesting a high risk of depression at the first visit and approximately one-third at visit two. Seventy-five percent of the mothers were at risk of suffering from an anxiety disorder at visit one and half remained so at visit two. A “depressed” score at visits one and two correlated with a hospitalization for a threatened premature labor. We noted a high risk of trauma for 35% of the mothers and high interactional synchrony was observed for approximately two-thirds of the dyads. The mothers' psychological reactions such as depression and anxiety or postnatal depression correlate strongly with the presence of an initial trauma. At visit one and visit two, a high score of satisfaction concerning social support correlates negatively with presence of a trauma. A maternal risk of trauma is more frequent with a C-section delivery. Conclusions Mothers' psychological reactions such as depression and anxiety correlate greatly with the presence of an initial trauma. The maternal traumatic reaction linked to premature birth does not correlate with the term at birth, but rather with the weight of the baby. Social support perceived by the mother is correlated with the absence of maternal trauma before returning home, and also seems to inhibit from depressive symptoms from the time of the infant's premature birth.

    Amylase activity was found in saliva from 13 infants, 26-42 wk corrected gestational age. The levels of salivary amylase activity increased with advancing age. In 10 infants, 31-38 wk corrected gestational age (estimated gestational age in wk plus age in wk after birth), gastric aspirates collected before a feeding and sequentially at 30-min intervals after two consecutive feedings were analyzed for amylase activity and pH. Two different postprandial patterns were obtained. For six of the 10 infants, both the pH and amylase activities of their gastric aspirates showed a distinct maxima at about 60 min after a feeding and a minima at 180 min just before the second feeding. In the remaining four infants, the pHs of their gastric aspirates remained relatively high (5.0-6.0) for the entire postprandial period. In these infants, there was a persistently high level of the amylase activity. In all 10 infants, amylase activity was found in their gastric aspirate samples when the pH was above 3.0. Comparison of the amylase in the gastric aspirate with purified pancreatic and salivary amylases by polyacrylamide gel electrophoresis showed that the amylase in the gastric aspirate has an electrophoretic mobility similar to that of salivary amylase, which suggests a salivary origin. This study supports the possibility that salivary amylase could enter the stomach and retain a significant amount of its activity in premature infants. PMID:6197692

    The aim of this study was to evaluate KL-6 and CC16 levels and their correlation with neurodevelopmental outcome among very low birth weight pre-term infants at 12 months corrected age. This prospective cohort study was performed from 2011 to 2013 by enrolling pre-term neonates of gestational age ≤ 32 weeks and birth weight ≤ 1500 g. Serum KL-6 and CC16 levels were determined 7 days after birth and their correlation with neurodevelopment was evaluated using Gesell Mental Developmental Scales. Of the 86 eligible pre-term infants, 63 completed follow-up, of which 15 had bronchopulmonary dysplasia. At 12 months corrected age, 49 infants had favorable outcomes and 14 infants had poor neurodevelopmental outcome. KL-6 levels were higher and CC16 levels were lower in infants with poor neurodevelopmental outcome compared with those infants who had favourable neurodevelopmental outcome. Serum KL-6 levels less than 90.0 ng/ml and CC16 levels greater than 320.0 pg/ml at 7 days of life were found to be predictive of a favourable outcome at 12 months corrected age. These biological markers could predict neurodevelopmental outcome at 12 months corrected age in very low birth weight premature infants, and help the clinician plan early therapeutic interventions to minimize or avoid poor neurodevelopmental outcome.

    Purpose To demonstrate the clinical characteristics and treatment outcomes of severe retinopathy of prematurity (ROP) in preterm infants with birth weight (BW) above 1500 g in Turkey. Methods A retrospective review of 5920 ROP records was performed in Zeynep Kamil Maternity and Children’s Diseases Training and Research Hospital. The records were obtained from ROP treatment center of the same institute between 2011 and 2016. The data comprised the demographic and clinical characteristics including, gestational age, BW, systemic risk factors, zone and stage of ROP, ROP type, treatment modality, treatment outcomes and inborn/outborn status of the babies. Results A total of 36 infants (71 eyes) with severe ROP and BW> 1500 g were retrieved. There were 30 infants (83.3%) with type 1 ROP and 6 infants (16.7%) with aggressive posterior ROP (APROP). 3 infants (8.3%) were born at our hospital whereas 33 (91.7%) were referred from outer private neonatal intensive care unit (NICU) centers. Zone I APROP was detected during the initial screening. 21 infants (58.3%) underwent laser treatment while 15 (41.7%) received intravitreal bevacizumab (IVB) injections. No unfavorable structural outcome was observed following either treatment modality. Conclusion Severe ROP may occur in heavier preterm infants. Laser treatment and IVB injections were useful in selected cases. Presence of APROP at first examination suggests an earlier screening in heavier babies. Standardization of private NICU centers as well as establishing a national ROP protocol is necessary in Turkey. PMID:27548628

    Expressed human milk is often used to feed premature infants. Raw milk contains bacteria which may be a source of infection. Milk banks have developed screening programs which combine periodic quantitative milk cultures with arbitrary rules specifying limits of bacterial concentration. It is unknown whether such programs succeed in preventing infants from being fed milk containing bacteria. At the Health Sciences Centre (Winnipeg, Manitoba, Canada), milk is screened once weekly. When a woman's milk is found to have excess bacteria, it is discarded only if she is an unrelated donor (as opposed to an infant's mother). To assess the effectiveness of this screening program, we determined the frequency at which infants fed raw human milk were exposed to milk-associated bacteria and compared the bacterial contents of donor and maternal milk. From February 1986 to April 1987, all human milk fed to 98 premature infants during the first 2 weeks of feeding (n = 10,128 feeds) was cultured quantitatively. Among study infants, 100% were exposed at least once to coagulase-negative staphylococci, 41% were exposed to Staphylococcus aureus, and 64% were exposed to gram-negative bacilli. The proportions of feeds containing bacteria and the quantities (log10 CFU [mean +/- standard deviation]) ingested per positive feed were: 39% and 5.9 +/- 0.5 for coagulase-negative staphylococci; 2.4% and 5.1 +/- 1.0 for S. aureus; and 5.2% and 4.8 +/- 1.1 for gram-negative bacilli. There were no adverse events attributable to ingestion of milk-associated bacteria. Milk coagulase-negative staphylococcal isolates were multiply antibiotic susceptible, whereas infant isolates were antibiotic resistant. Donor milk was significantly less likely than maternal milk to contain coagulase-negative staphylococcal species in any quantity (40 versus 93% of samples, respectively [P < 0.001]) or in concentrations exceeding 10(8) CFU/liter (3 versus 27% of samples, respectively [P < 0.0001]).

    Oral feeding is a developmental task for all premature infants. often, independent nipple feeding is the last barrier to discharge home from the NICU. A relationship exists between consistent, infant-driven feeding management practices and improved feeding performance. Conversely, a random approach to feeding may contribute to poor short-term and long-term clinical outcomes. We report a quality improvement project that was undertaken across five NICUs in an urban setting. our aim was to safely initiate and advance nipple feeding for very preterm neonates (born at <32 weeks gestation) who had a respiratory morbidity requiring nasal continuous positive airway pressure therapy. A novel algorithm entitled "eating in SINC: Safe individualized nipple-Feeding Competence" was developed. Safe individualized nipple-feeding competence involves the baby, the parents, and the health care team by using infant-driven strategies, common language, and developmentally appropriate goals while supporting fragile neonates to be skilled feeders.

    Purpose This study aimed to evaluate predictive factors involved in efficacy and safety in Japanese infants who received theophylline therapy to prevent apnea of prematurity (AOP) after weaning from mechanical ventilation. Methods We retrospectively reviewed the medical records of infants who were administered intravenous aminophylline (theophylline ethylenediamine) for AOP at the neonatal intensive care unit, Kagoshima University Hospital, Japan, between January 2009 and June 2013. Results A total of 100 infants were evaluated as two separate groups in terms of efficacy and safety of theophylline. Sixty-seven (67.0%) infants had effective theophylline therapy. Multivariate logistic regression analysis showed that gestational age at birth was significant, with an odds ratio of 0.59 (p < 0.001). Receiver operating characteristic analysis showed that the cut-off value was 31.1 weeks old for predicting the efficacy of theophylline (specificity, 66.7%; sensitivity, 86.6%; p < 0.001; area under the curve, 0.750; 95% confidence interval, 0.45–0.74). Adverse reactions were identified in 21 (21.0%) infants. Multivariate logistic regression analysis showed that the number of days of theophylline administration from birth was associated with an increased risk of adverse reactions after theophylline administration (p = 0.01). Conclusions Physicians need to be aware of the possibility that theophylline fails to produce therapeutic effects for extubation in infants aged less than 31.1 weeks old, and adverse reactions can easily develop when theophylline is administered soon after birth.

    Background Linoleic 18:2 (n-6) and α-linolenic 18:3 (n-3) essential fatty acids and long-chain polyunsaturated fatty acids (LC-PUFA) are essential nutrients for growth and neonatal development. Consumption of preformed n-3 LC-PUFA has been shown to increase gestational duration and to decrease the incidence of premature birth in human studies. This study evaluated the association of essential fatty acids and LC-PUFA in breast milk on the growth of premature children (weight, height and head circumference). Study design Thirty-seven premature infants with a gestational age of 37 weeks or less were followed until 6 months of gestational age, adjusted for prematurity. The milk from mothers, weight, height and head circumference measures of children were collected during the follow up. The breast milk fatty acids were quantified by gas-liquid chromatography. Results Our results showed that total n-3 PUFA was positively associated with weight gain (p = 0.05), height (p = 0.04) and body mass index (BMI) of children (p = 0.05). Our results also indicate that both linoleic acid and total essential fatty acids were positively associated with BMI and head circumference, whereas oleic acid was positively associated only with head circumference. Conclusion These results suggest that the n-3 PUFA composition of milk may be associated with weight gain and growth. Considering the advantages of n-3 LC-PUFA consumption on infant growth and visual function and its association with reduced incidence of premature birth, dietitians should advise pregnant women to increase their intake of foods high in n-3 LC-PUFA.

    Objective The adequacy of informed consent in the Surfactant, Positive Pressure, and Pulse Oximetry Randomized Trial (SUPPORT) has been questioned. SUPPORT investigators and publishing editors, heads of government study funding agencies, and many ethicists have argued that informed consent was adequate because the two oxygen saturation target ranges studied fell within a range commonly recommended in guidelines. We sought to determine whether each oxygen target as studied in SUPPORT and four similar randomized controlled trials (RCTs) was consistent with usual care. Design/Participants/Setting PubMed, EMBASE, Web of Science, and Scopus were searched for English articles back to 1990 providing information on usual care oxygen management in extremely premature infants. Data were extracted on intended and achieved oxygen saturation levels as determined by pulse oximetry. Twenty-two SUPPORT consent forms were examined for statements about oxygen interventions. Results While the high oxygen saturation target range (91 to 95%) was consistent with usual care, the low range (85 to 89%) was not used outside of the SUPPORT trial according to surveys and clinical studies of usual care. During usual care, similar lower limits (< 88%) were universally paired with higher upper limits (≥ 92%) and providers skewed achieved oxygen saturations toward the upper-end of these intended ranges. Blinded targeting of a low narrow range resulted in significantly lower achieved oxygen saturations and a doubling of time spent below the lower limit of the intended range compared to usual care practices. The SUPPORT consent forms suggested that the low oxygen saturation arm was a widely practiced subset of usual care. Conclusions SUPPORT does not exemplify comparative effectiveness research studying practices or therapies in common use. Descriptions of major differences between the interventions studied and commonly practiced usual care, as well as potential risks associated with these

    In this study, we examined the relations between the severity of developmental outcomes of extremely low birth weight (ELBW) children and their mothers' stress and post-traumatic stress disorder (PTSD) symptoms, 4-16 years after birth. Israeli mothers (N = 78) of a cohort of extremely premature infants (24-27 weeks) born 4-16 years earlier were asked to report about the medical and developmental condition of their child and their current perceived stress and PTSD symptoms. Results show that mothers of ELBW children with normal development reported the lowest perceived stress compared with mothers of ELBW children with developmental difficulties. We also found that 25.6% of the mothers had the potential to suffer from PTSD following the birth of an ELBW child. Furthermore, the severity of prematurity developmental outcomes made a significant contribution to mothers' perceived stress. To sum, mothers of ELBW infants' perceived stress is related to their children's severity of prematurity developmental outcomes, 4-16 years after birth. Clinical implications of these findings are discussed. PMID:26252160

    This article explores the feasibility of running "PremieStart," a nine-individual-session maternal-premature infant interaction program, within a neonatal unit (NNU) in England. Four mothers of premature infants completed seven sessions on the NNU and two at home. Mothers and NNU staff provided feedback on PremieStart. Measures of maternal-infant relationship, maternal well-being, and maternal reflective functioning were completed before and after intervention. Thematic analysis of mothers' feedback highlighted the emotional, but cathartic, experience of engaging with PremieStart. NNU staff feedback indicated the need to include them more in PremieStart. Both mothers and staff were supportive of future implementation of PremieStart and highlighted the ongoing need for psychological support on the NNU. PremieStart was implemented with positive feedback from mothers and staff, with support shown for the continued use of PremieStart in the NNU. However, for future implementation, the self-report outcome measures need reviewing, and more involvement of fathers and NNU staff is needed. In addition, a larger sample with a control group should be utilized. PMID:27348583

    Preeclampsia and retinopathy of prematurity (ROP) are associated with impaired angiogenesis. Previous studies on the relationship between preeclampsia and ROP have produced conflicting results. The goal of this study was to evaluate the association between maternal preeclampsia and ROP using a large population-based cohort of very-low-birth-weight (VLBW) infants from 21 neonatal departments registered in the database of the Premature Baby Foundation of Taiwan. Multivariable logistic regression analysis was used to estimate the adjusted odds ratios (OR) and 95% confidence intervals (CI) for preeclampsia with reference to ROP and severe ROP. A total of 5,718 VLBW infants (844 cases with maternal preeclampsia) were included for analysis. The overall incidences of mild and severe ROP were 36.0% and 12.2%, respectively. Univariable analysis showed lower GA and lower birth weight, vaginal delivery, non-SGA, RDS, PDA, sepsis, transfusion, and absence of maternal preeclampsia to be associated with mild and severe ROP development. However, OR (95% CI) adjusted for the variables that were significant according to univariable analysis showed the risks of developing any-stage ROP and severe ROP for maternal preeclampsia to be 1.00 (0.84–1.20) and 0.89 (0.63–1.25), respectively. The results remained unchanged in stratified analyses according to SGA status. Our data showed that maternal preeclampsia was not associated with the subsequent development of any stage or severe ROP in VLBW infants. PMID:26588850

    This study was conducted to describe the incidence, risk factors, and current treatment status of retinopathy of prematurity (ROP) in very-low-birth-weight (VLBW) infants registered in the Korean Neonatal Network database. Medical records of 2,009 VLBW infants born between January 2013 and June 2014 who underwent examination by an ophthalmologist were reviewed. The total incidence of ROP was 34.1%. Of the patients, 11.6% showed ROP stage ≥ 3 and 11.5% received treatment of VLBW. Among all infants who received treatment of ROP, 63.6% underwent operation only; 16.9%, anti-vascular endothelial growth factor (anti-VEGF) treatment only; and 19.5%, both operation and anti-VEGF treatment. The mean gestational age (GA) and birth weight (BW) were significantly lower and the prevalence rates of respiratory distress syndrome, patent ductus arteriosus (PDA), invasive ventilator duration, and sepsis were significantly higher in the VLBW infants with ROP than in those without ROP. In the multivariable logistic regression analysis, PDA (odd ratio [OR], 2.1; 95% confidence interval [CI], 1.11-3.79) and invasive ventilator duration (OR, 1.0; 95% CI, 1.00-1.02) were significant risk factors of ROP and ROP stage ≥ 3. In conclusion, the high incidence of ROP is associated with low GA and BW, and attempt to reduce the aforementioned risk factors could reduce the incidence of ROP stage ≥ 3 in VLBW infants.

    As younger preterm infants are able to survive, more extremely preterm infants are at risk of developing retinopathy of prematurity (ROP). To investigate the incidence, progression and risk factors of ROP in extremely preterm infants in Korea, the medical records of infants born before 25 weeks gestation were retrospectively reviewed. The criteria for laser treatment agreed with type 1 ROP as defined by the Early Treatment for Retinopathy of Prematurity study. Of the 121 infants included in the analysis, 119 (98.4%) infants developed any stage ROP, including 78 infants (64.5%) with type 1 ROP. The mean postmenstrual age (PMA) at the onset of any ROP and type 1 ROP were 33.5 and 36.1 weeks, respectively. All but one infant developed type 1 ROP after 31 weeks PMA. Univariate analysis showed that duration of total parenteral nutrition and onset of any ROP (PMA) were associated with the development of type 1 ROP. In conclusion, this study shows high incidence of ROP in extremely preterm infants and suggests that, although current screening protocols are feasible for most preterm infants born before 25 weeks gestation, earlier screening before 31 weeks PMA may be necessary in infants with an unstable clinical course.

    The relative potency and interrelationship between vasoactive and natriuretic mediators are thought to be important in the transition from fetal to neonatal life. The relationship between urinary vasoactive factors and sodium excretion has not been adequately addressed in premature infants receiving indomethacin and ibuprofen for therapy of patent ductus arteriosus. Excretion rates of AVP, ET-1 and sodium were measured in premature infants with RDS receiving indomethacin or ibuprofen. Forty-four RDS premature infants (<34-week gestation) with PDA received either ibuprofen (n=22) in an initial dose of 10 mg/kg followed by two doses of 5 mg/kg each after 24 and 48 h or 3 doses at 12-h intervals of indomethacin (n=24), 0.2 mg/kg, infused continuously over a period of 15 min. Urinary ET-1, AVP and sodium excretion were measured before and after treatment. Indomethacin treatment caused a significant decrease in urinary ET-1 and AVP excretion (UET-1/Ucr 0.14+/-0.01 vs. 0.10+/-0.05 fenton/mmol; P<0.05; 24.42+/-6.18 vs. 12.63+/-3.06 pg/mmol; P<0.05, respectively), along with a significant reduction in urinary sodium (92.1+/-36.1 vs. 64.8+/-35.6 mmol/l; P<0.01), fractional excretion of sodium (6.8+/-37.1 vs. 4.5+/-37.1%; P<0.01) and urinary osmolality (276.2+/-103.9 vs. 226.4+/-60.3 mOsmol/kg; P<0.05). Ibuprofen treatment caused a significant decrease in urinary AVP (UAVP/Ucr 24.5+/-3.4 vs. 16.3+/-2.04 pg/mmol; P<0.01), along with a significant decrease in urinary sodium (78.0+/-8.4 vs. 57.0+/-8.0 mmol/l; P<0.05) and in fractional excretion of sodium (7.5+/-1.3 vs. 3.9+/-3.0%; P<0.05), while it did not modify urinary ET-1 excretion. The association of renal ET-1 and AVP activity with sodium excretion in premature infants treated with indomethacin and ibuprofen supports the hypothesis that these factors may play a role in the physiologic changes in sodium excretion.

    Purpose. To retrospectively study the effect of fish oil-based lipid emulsion and soybean oil-based lipid emulsion on cholestasis associated with long-term parenteral nutrition in premature infants. Methods. Soybean oil-based lipid emulsion and fish oil-based lipid emulsion had been applied in our neonatology department clinically between 2010 and 2014. There were 61 qualified premature infants included in this study and divided into two groups. Soybean oil group was made up of 32 premature infants, while fish oil group was made up of 29 premature infants. Analysis was made on the gender, feeding intolerance, infection history, birth weight, gestational age, duration of parenteral nutrition, total dosage of amino acid, age at which feeding began, usage of lipid emulsions, and incidence of cholestasis between the two groups. Results. There were no statistical differences in terms of gender, feeding intolerance, infection history, birth weight, gestational age, duration of parenteral nutrition, total dosage of amino acid, and age at which feeding began. Besides, total incidence of cholestasis was 21.3%, and the days of life of occurrence of cholestasis were 53 ± 5.0 days. Incidence of cholestasis had no statistical difference in the two groups. Conclusion. This study did not find the different role of fish oil-based lipid emulsions and soybean oil-based lipid emulsions in cholestasis associated with long-term parenteral nutrition in premature infants.

    An increasing incidence of bronchopulmonary dysplasia (BPD) in premature infants has been reported in recent years. In the present study we analyzed the risk factors for BPD. It was revealed that the most significant factors are the low gestational age and birth weight, as well as prolonged use of mechanical ventilation and late neonatal infection. Polymorphism of studied genes and various combinations of polymorphic variants did not affect the risk of BPD developing. The influence of genetic polymorphisms on the duration of mechanical ventilation, the occurrence of late neonatal infection. For proper evaluation of the contribution of genetic polymorphism is necessary to conduct a preliminary analysis of all possible clinical and laboratory parameters to identify strong independent predictors and then analyze the indirect effects of genetic factors. Further research and development of new approaches to ventilation mode in preterm infants, based on the genetic polymorphism, will create a set of preventive measures and reduce the incidence of BPD.

    Background: Premature infants are subjected to many painful procedures during care and treatment. The aim of this study was to assess the effect of music therapy on physiological and behavioral pain responses of premature infants during and after blood sampling. Materials and Methods: This study was a cross-over clinical trial conducted on 20 infants in a hospital affiliated to Tehran University of Medical Sciences for a 5-month period in 2011. In the experimental group, Transitions music was played from 5 min before until 10 min after blood sampling. The infants’ facial expressions and physiological measures were recorded from 10 min before until 10 min after sampling. All steps and measurements, except music therapy, were the same for the control group. Data were analyzed using SAS and SPSS software through analysis of variance (ANOVA) and Chi-square tests. Results: There were significant differences between the experimental and control groups (P = 0.022) in terms of heart rate during needle extraction and at the first 5 min after sampling (P = 0.005). Considering the infant's sleep–wake state in the second 5 min before sampling, the statistical difference was significant (P = 0.044). Difference was significant (P = 0.045) during injection of the needle, in the first 5 min after sampling (P = 0.002), and in the second 5 min after sampling (P = 0.005). There were significant difference in infants’ facial expressions of pain in the first 5 min after sampling (P = 0.001). Conclusions: Music therapy reduces the physiological and behavioral responses of pain during and after blood sampling. PMID:27563323

    Ten premature infants nursed on servocontrolled radiant warmer beds were studied in three environments designed to alter one or more factors affecting heat transfer (convection, evaporation, and radiation). In the control environment, infants were nursed supine on an open warmer bed. The second environment (walled chamber) was designed to reduce convection and evaporation by placing plastic walls circumferentially around the bed. In the third environment convection and evaporation were minimized by covering infants with a plastic blanket. Air turbulence, insensible water loss, and radiant warmer power were measured in each environment. There was a significant reduction in mean air velocity in the walled chamber and under the plastic blanket when compared to the control environment. A parallel decrease in insensible water loss occurred. In contrast, radiant power demand was the same for control and walled environments, but decreased significantly when infants were covered by the plastic blanket. This study suggests that convection is an important factor influencing evaporation in neonates nursed under radiant warmers. The thin plastic blanket was the most effective shield, significantly reducing radiant power demand.

    Caffeine, standard treatment for apnea of prematurity, improves brainstem auditory processing. We hypothesized that caffeine also improves cortical differentiation of complex speech sounds. We used event-related potential methodology to measure responses to speech-sound contrasts in 45 intensive care neonates, stratified by cumulative exposure as no-, low-, and high-caffeine groups. Sound differentiation in the low-caffeine group and near-term no-caffeine infants was similar with repeated measures analysis of variance controlling for gestational and postnatal age. However, a generalized estimating equation approach demonstrated that, at equivalent postnatal age, differentiation was reduced in the high-caffeine (gestational age 25 weeks) compared to the low-caffeine group (gestational age 28 weeks), reflecting the importance of maturity at birth (Z = 2.77, P < .006). We conclude that caffeine improves measures of auditory processing associated with improved neurodevelopmental outcomes in preterm infants. However, current usage of caffeine for apnea of prematurity cannot fully compensate for the effects of brain immaturity on speech sound processing. PMID:24939976

    This prospective longitudinal study examined predictors of parenting stress trajectories over time in a sample of 125 mothers and their preterm infants. Infant (multiple birth, gestational age, days hospitalized, and neonatal health risks) and maternal (socioeconomic, education, depressive symptoms, social support, and quality of interaction during infant feeding) characteristics were collected just prior to infant hospital discharge. Parenting stress and maternal interaction quality during play were measured at 4, 24, and 36 months corrected age. Hierarchical linear modeling was used to analyze infant and maternal characteristics as predictors of parenting stress scores and change over time. Results indicated significant variability across individuals in parenting stress at 4 months and in change trajectories. Mothers of multiples and infants with more medical risks and shorter hospitalization, and mothers with lower education and more depressive symptoms, reported more parenting stress at 4 months of age. Parenting stress decreased over time for mothers of multiples and for mothers with lower education more than for mothers of singletons or for mothers with higher educational levels. Changes in parenting stress scores over time were negatively associated with maternal behaviors during mother-infant interactions. Results are interpreted for their implications for preventive interventions. PMID:24188086

    Prematurity is by far the commonest cause of neonatal morbidity and mortality. The management of premature labour is empirical because little is understood about the mechanism of labour. Effective uterine relaxant drugs have an important, albeit minor role. Phototherapy has reduced the complications of neonatal hyperbilirubinemia, and the beneficial effect of antepartum corticosteroid therapy in minimizing the risk of respiratory distress syndrome is now convincing. Prophylactic antibiotic therapy in premature rupture of the membranes does not alter perinatal mortality, although postpartum maternal morbidity is reduced. The introduction of neonatal intensive care units has improved the survival rate of premature infants. Sound clinical judgement remains the mainstay in the management of premature labour. PMID:4217

    Nutrition support practitioners are currently dealing with shortages of parenteral nutrition micronutrients, including multivitamins (MVI), selenium and zinc. A recent survey from the American Society of Enteral and Parenteral Nutrition (ASPEN) indicates that this shortage is having a profound effect on clinical practice. A majority of respondents reported taking some aggressive measures to ration existing supplies. Most premature infants and many infants with congenital anomalies are dependent on parenteral nutrition for the first weeks of life to meet nutritional needs. Because of fragile health and poor reserves, they are uniquely susceptible to this problem. It should be understood that shortages and rationing have been associated with adverse outcomes, such as lactic acidosis and Wernicke encephalopathy from thiamine deficiency or pulmonary and skeletal development concerns related to inadequate stores of Vitamin A and D. In this review, we will discuss the current parenteral shortages and the possible impact on a population of very low birth weight infants. This review will also present a case study of a neonate who was impacted by these current shortages. PMID:23223000

    Purpose This study investigated whether vergence and accommodation development in pre-term infants is pre-programmed or is driven by experience. Methods 32 healthy infants, born at mean 34 weeks gestation (range 31.2-36 weeks) were compared with 45 healthy full-term infants (mean 40.0 weeks) over a 6 month period, starting at 4-6 weeks post-natally. Simultaneous accommodation and convergence to a detailed target were measured using a Plusoptix PowerRefII infra-red photorefractor as a target moved between 0.33m and 2m. Stimulus/response gains and responses at 0.33m and 2m were compared by both corrected (gestational) age and chronological (post-natal) age. Results When compared by their corrected age, pre-term and full-term infants showed few significant differences in vergence and accommodation responses after 6-7 weeks of age. However, when compared by chronological age, pre-term infants’ responses were more variable, with significantly reduced vergence gains, reduced vergence response at 0.33m, reduced accommodation gain, and increased accommodation at 2m, compared to full-term infants between 8-13 weeks after birth. Conclusions When matched by corrected age, vergence and accommodation in pre-term infants show few differences from full-term infants’ responses. Maturation appears pre-programmed and is not advanced by visual experience. Longer periods of immature visual responses might leave pre-term infants more at risk of development of oculomotor deficits such as strabismus. PMID:26275135

    The associations between a mother's rigidity, her sensitivity in early (3 month) interaction and the quality of her premature infant's attachment at 13 months were investigated. Rigidity as a personality characteristic was not found to be significantly associated with sensitivity or quality of attachment. Rigid attitudes to child rearing were related to sensitivity and to the responsivity of the infant. Rigid attitudes were not related to security of attachment. Infants who were rated less responsive at 3 months, however, tended to be less securely attached, and high Attitude Rigidity in the mother increased their chances of an insecure attachment.

    The aim of this study was to describe how the parents of premature infants experience the transportation of their baby from the neonatal intensive care unit at a university hospital (NICU-U) to such a unit at a local hospital (NICU-L). This descriptive qualitative study comprises interviews with nine sets of parents and two mothers. The qualitative content analysis resulted in one theme: living in uncertainty about whether the baby will survive, and three categories: being distanced from the baby; fearing that something would happen to the baby during transportation; and experiencing closeness to the baby. The results also revealed that the parents experienced developmental, situational and health-illness transitions. PMID:24582644

    The neonatal period of very preterm infants is often characterized by a difficult adjustment to extrauterine life, with an inadequate nutrient supply and insufficient levels of growth factors, resulting in poor growth and a high morbidity rate. Long-term multisystem complications include cognitive, behavioral, and motor dysfunction as a result of brain damage as well as visual and hearing deficits and metabolic disorders that persist into adulthood. Insulinlike growth factor 1 (IGF-1) is a major regulator of fetal growth and development of most organs especially the central nervous system including the retina. Glucose metabolism in the developing brain is controlled by IGF-1 which also stimulates differentiation and prevents apoptosis. Serum concentrations of IGF-1 decrease to very low levels after very preterm birth and remain low for most of the perinatal development. Strong correlations have been found between low neonatal serum concentrations of IGF-1 and poor brain and retinal growth as well as poor general growth with multiorgan morbidities, such as intraventricular hemorrhage, retinopathy of prematurity, bronchopulmonary dysplasia, and necrotizing enterocolitis. Experimental and clinical studies indicate that early supplementation with IGF-1 can improve growth in catabolic states and reduce brain injury after hypoxic/ischemic events. A multicenter phase II study is currently underway to determine whether intravenous replacement of human recombinant IGF-1 up to normal intrauterine serum concentrations can improve growth and development and reduce prematurity-associated morbidities.

    Aim of this study was to estimate the cost that is borne by the Italian National Health Service, families, and social security due to very low birth weight infants (VLBWIs) without prematurity-related morbidities up to the age of 18 months. We followed up on 150 VLBWIs and 145 comparable full-term infants (FTIs) who were born in one of 25 different neonatal intensive care units upon discharge from the hospital and at six and 18 months of age. The average length of the primary hospitalisation of the VLBWIs was 59.7 days (SD 21.6 days), with a total cost of €20,502 (SD €8409), compared with three days (SD 0.4 days) with a total cost of €907 (SD €304) for the FTIs. The total societal cost of the VLBWIs for the first 18 months of life was €58,098 (SD €21,625), while the corresponding figure for FTIs was €24,209 (SD €15,557). Among VLBWIs, both low birth weight and gestational age were correlated with the length of hospitalisation after birth (r(2) = 0.61 and r(2) = 0.57, respectively; p values < 0.0005). Our findings highlight that the existing DRGs and tariffs inadequately reflect the actual costs for Italian National Health Service. PMID:26286526

    Background Pulmonary disease among infants of <28 weeks' gestation (extremely low gestational age newborns) often has the following pattern: the infant starts out with little need for supplemental oxygen and ventilatory support in the first postnatal week but then has pulmonary deterioration in the second postnatal week, with an increased need for supplemental oxygen and respiratory support. We evaluated the antecedents and correlates of patterns of early lung disease, with particular emphasis on pulmonary deterioration, in a large cohort study (the Extremely Low Gestational Age Newborn [ELGAN] study). Patients and Methods We examined data collected prospectively on 1340 infants born between 2002 and 2004 at 23 to 27 completed weeks of gestation and who survived to 14 days. Pulmonary deterioration was defined as receipt of fraction of inspired oxygen <0.23 on any day between days 3 and 7 and receipt of fraction of inspired oxygen ≥ 0.25 on day 14. Results One fifth (20%) of the infants had consistently low fraction of inspired oxygen, approximately two fifths (38%) had pulmonary deterioration, and the remaining approximately two fifths (43%) had consistently high fraction of inspired oxygen (early and persistent lung dysfunction). Compared with infants who had consistently low fraction of inspired oxygen, infants who experienced pulmonary deterioration had lower gestational ages and lower birth weights, had higher scores for neonatal acute physiology, and received more intensive modes of respiratory support. Gender, multifetal pregnancy, cesarean delivery, antenatal steroids, chorioamnionitis, and funisitis were not associated with pulmonary deterioration. The incidence of chronic lung disease, defined as oxygen therapy at 36 weeks' postmenstrual age, was 17% in the consistently low fraction of inspired oxygen group, 51% in the pulmonary deterioration group, and 67% in the early and persistent pulmonary dysfunction group. The incidence of death in these 3 groups

    We introduced continuous intravenous infusion of amphotericin-B (AMPH-B) to extremely low birthweight (ELBW) infants (< 1000 g) with or without renal failure as a single agent for treating definite or probable systemic candidiasis. The species of Candida isolated from blood or tracheal aspirate or urine were C. albicans in seven infants, C glabrata in two, C. tropicalis in one and C. parapsilosis in one. The minimal inhibitory concentrations (MIC) of AMPH-B required against these isolates were less than 0.2 micrograms/mL except for that against one strain of C. albicans (0.78 microgram/mL). Serum AMPH-B levels were 0.31-0.78 (0.51 +/- 0.14) micrograms/mL when doses of 0.2-0.55 (0.32 +/- 0.11) mg/kg per day were being administered. The serum level was higher than the MIC of each isolate in all but one infant who died of disseminated intravascular coagulation and Candida pneumonia. Another infant died of congenital heart disease. The other nine infants survived. The serum level showed no correlation with the daily dose. The ratio of the serum level to the daily dose (L/D ratio) showed a significant correlation to serum creatinine (r = 0.787) and the linear regression curve followed the equation: L/D ratio = 0.223 x serum creatinine + 1.11 (P < 0.01). Few adverse effects due to AMPH-B were noted. Our data may give a simple reference to serum AMPH-B levels during continuous intravenous infusion from the dose and the serum creatinine level.

    The development of pulmonary hypertension (PH) is a serious complication of bronchopulmonary dysplasia (BPD) among infants born at extremely low gestational ages. Bronchopulmonary dysplasia-associated PH is characterized by persistent pulmonary vasoconstriction, progressive right heart dysfunction, and an increased risk of death. We have shown previously that certain placental vascular lesions are associated with BPD-associated PH. Further evaluation of the villous and vascular morphometry of these placentas is warranted. Using digital image analysis (DIA), we compared villous and vascular morphometric parameters of placentas from infants with and without BPD-associated PH. We conducted a case-control study of placentas from 14 infants born at ≤28 weeks' gestational age (GA). Cases with PH (N=7) and non-PH controls (N=7) were identified using echocardiogram screening at 36 weeks' corrected GA. Central parenchymal sections from each placenta were stained for CD31. Digital image analysis was used to measure vessel and villous capillary number, perimeter, diameter, and area. Mean villous vascularity (number of vessels per villus) was calculated for each patient. Mean vessel and villous number as well as area were similar between the two groups. Villous vascularity was decreased in placentas from infants who ultimately had PH disease compared to non-PH controls (5.5±1.0 vs 7.1±1.6; P<0.05). Placental villous vascularity is decreased in infants with BPD-associated PH. Further studies should assess whether placental morphometric markers may allow clinicians to better predict BPD and provide earlier and more targeted management. PMID:26366786

    Objective The aim of this work was to determine the radiation dose received by infants from radiographic exposure and the contribution from scatter radiation due to radiographic exposure of other infants in the same room. Materials and Methods We retrospectively evaluated the entrance skin doses (ESDs) and effective doses of 23 infants with a gestational age as low as 28 weeks. ESDs were determined from tube output measurements (ESDTO) (n = 23) and from the use of thermoluminescent dosimetry (ESDTLD) (n = 16). Scattered radiation was evaluated using a 5 cm Perspex phantom. Effective doses were estimated from ESDTO by Monte Carlo computed software and radiation risks were estimated from the effective dose. ESDTO and ESDTLD were correlated using linear regression analysis. Results The mean ESDTO for the chest and abdomen were 67 µGy and 65 µGy per procedure, respectively. The mean ESDTLD per radiograph was 70 µGy. The measured scattered radiation range at a 2 m distance from the neonatal intensive care unit (NICU) was (11-17 µGy) per radiograph. Mean effective doses were 16 and 27 µSv per procedure for the chest and abdomen, respectively. ESDTLD was well correlated with ESDTO obtained from the total chest and abdomen radiographs for each infant (R2 = 0.86). The radiation risks for childhood cancer estimated from the effective dose were 0.4 × 10-6 to 2 × 10-6 and 0.6 × 10-6 to 2.9 × 10-6 for chest and abdomen radiographs, respectively. Conclusion The results of our study show that neonates received acceptable doses from common radiological examinations. Although the contribution of scatter radiation to the neonatal dose is low, considering the sensitivity of the neonates to radiation, further protective action was performed by increasing the distance of the infants from each other.

    Several studies have reported that feeding gamma-linolenic acid (GLA) has resulted in no increase in arachidonic acid (AA) in newborns. This result was ascribed to the eicosapentaenoic acid (EPA)-rich fish oil used in these formulas. Docosahexaenoic acid (DHA) sources with only minor amounts of EPA are now available, thus the addition of GLA to infant formulas might be considered an alternative to AA supplementation. Sixty-six premature infants were randomized to feeding one of four formulas [ST: no GLA, no long-chain polyunsaturated fatty acids; BO: 0.6% GLA (borage oil); BO + FOLOW: 0.6% GLA, 0.3% DHA, 0.06% EPA; BO + FOHIGH: 0.6% GLA, 0.3% DHA, 0.2% EPA] or human milk (HM, nonrandomized) for 4 wk. Anthropometric measures and blood samples were obtained at study entry and after 14 and 28 d. There were no significant differences between groups in anthropometric measures, tocopherol, and retinol status at any of the studied time points. The AA content of plasma phospholipids was similar between groups at study start and decreased significantly until day 28 in all formulafed groups, but not in the breast-fed infants [ST: 6.6 +/- 0.2%, BO: 6.9 +/- 0.3%, BO + FOLOW: 6.9 +/- 0.4%, BO + FOHIGH: 6.7 +/- 0.2%, HM: 8.6 +/- 0.5%, where values are reported as mean +/- standard error; all formulas significantly different (P< 0.05) from HM]. There was no significant influence of GLA or fish oil addition to the diet. GLA had only a very limited effect on AA status which was too small to obtain satisfactory concentrations (concentrations similar to breast-fed babies) under the circumstances tested. The effect of GLA on AA is independent of the EPA and DHA content in the diet within the dose ranges studied. PMID:11485158

    Preterm infants in the neonatal intensive care unit (NICU) often close their eyes in response to bright lights, but they cannot close their ears in response to loud sounds. The sudden transition from the womb to the overly noisy world of the NICU increases the vulnerability of these high-risk newborns. There is a growing concern that the excess noise typically experienced by NICU infants disrupts their growth and development, putting them at risk for hearing, language, and cognitive disabilities. Preterm neonates are especially sensitive to noise because their auditory system is at a critical period of neurodevelopment, and they are no longer shielded by maternal tissue. This paper discusses the developmental milestones of the auditory system and suggests ways to enhance the quality control and type of sounds delivered to NICU infants. We argue that positive auditory experience is essential for early brain maturation and may be a contributing factor for healthy neurodevelopment. Further research is needed to optimize the hospital environment for preterm newborns and to increase their potential to develop into healthy children. PMID:22524335

    A new to-and-fro V-V bypass extracorporeal lung assist (ECLA) through a single catheter as a blood access was investigated for its efficacy on six premature goats delivered by Cesarean section at a gestational age of 118 approximately 139 days as an experimental model of infant respiratory insufficiency, then applied to a human premature infant suffering from life threatening barotrauma that had developed from mechanical pulmonary ventilation. The extracorporeal bypass flow and the gas flow to the artificial membrane lung were controlled to keep Pa(O)(2) above 40 mmHg and Pa(CO)(2) within normal limits. The neonate's own lungs were treated with a continuous positive airway pressure of 5 approximately 12 cmH(2)O, apneic oxygenation or IMV. Two goats weighing 1250 g and 700 g died 2 approximately 2.5 hours after birth from severe circulatory distress. However, the other four neonates which were heavier than 2000 g, were successfully weaned from ECLA, and three of these could be weaned from mechanical ventilation as well. A human infant also survived and was weaned from ECLA on the third day.(Tanoue T, Terasaki H, Sadanaga M et al.: To-and-fro extracorporeal lung assist (ECLA) through a single catheter-in premature goats as an experimental model of infant respiratory insufficiency.

    Surgical ligation for patent ductus arteriosus (PDA) in extremely low birth weight infants (ELBWIs) has been shown a possible association with neurodevelopmental impairment (NDI) because of its invasiveness. However, we have undergone surgical ligation for ELBWIs immediately after cyclooxygenase inhibitor failed to close a hemodynamically significant PDA (hsPDA) to maintain proper systemic circulation. We aimed to determine the effect of surgical ligation for hsPDA on NDI in ELBWIs. In enrolled 71 ELBWIs, the clinical parameters, including the developmental quotient (DQ), were collected and compared among three groups that were divided by closure mode: spontaneous closure (n = 11), cyclooxygenase inhibitor therapy (n = 37) and surgical ligation (n = 23). No significant differences in DQ at the age of 36 months among the three groups were found: Median (interquartile range): 92.0 (31.0), 89.0 (22.0) and 92.0 (24.5), respectively. In a comparison between groups of DQ < 70 (n = 15) and DQ ≥ 70 (n = 56), a significant difference was found in the parameters related to prematurity (p < 0.05 for each): gestational age [23.9 (1.70) vs. 25.4 (2.50) weeks], birth weight [595 (183) vs. 714 (192) g], Apgar score < 5 (1 min) (67% vs. 36%), and laser photocoagulation for retinopathy of prematurity (73% vs. 43%), but there was no significant association with hsPDA. Therefore, we propose that surgical ligation for hsPDA in ELBWIs should be immediately carried out for preventing future neurodevelopmental deterioration if the cyclooxygenase inhibitor failed to close hsPDA.

    Despite surfactant and mechanical ventilation being the standard of care for preterm infants with respiratory failure, non-invasive respiratory support is increasingly being employed in neonatal units. The latter can be accomplished in a variety of ways but none of them have been proven so far to be superior to intubation and mechanical ventilation. Nonetheless, they appear to be safe and effective in experienced hands. This article relates to the use of non-invasive forms of respiratory support and evidence is reviewed from the clinical trials which have evaluated the use of these techniques. PMID:24404523

Early weaning from mechanical ventilation to noninvasive respiratory support decreases ventilation-associated irreversible lung damage. This wean is particularly challenging in PIs with cleft lip and cleft palate due to anatomical difficulties encountered in maintaining an adequate seal for positive pressure ventilation. PI with a cleft lip and palate often fail noninvasive respiratory support and require continued intubation and mechanical ventilation. We are presenting the first case report of a PI with cleft lip and palate who was managed by biphasic nasal continuous positive airway pressure. PMID:26495158

  17. A Bayesian approach to the characterization of electroencephalographic recordings in premature infants

    NASA Astrophysics Data System (ADS)

    Mitchell, Timothy J.

    Preterm infants are particularly susceptible to cerebral injury, and electroencephalographic (EEG) recordings provide an important diagnostic tool for determining cerebral health. However, interpreting these EEG recordings is challenging and requires the skills of a trained electroencephalographer. Because these EEG specialists are rare, an automated interpretation of newborn EEG recordings would increase access to an important diagnostic tool for physicians. To automate this procedure, we employ a novel Bayesian approach to compute the probability of EEG features (waveforms) including suppression, delta brushes, and delta waves. The power of this approach lies not only in its ability to closely mimic the techniques used by EEG specialists, but also its ability to be generalized to identify other waveforms that may be of interest for future work. The results of these calculations are used in a program designed to output simple statistics related to the presence or absence of such features. Direct comparison of the software with expert human readers has indicated satisfactory performance, and the algorithm has shown promise in its ability to distinguish between infants with normal neurodevelopmental outcome and those with poor neurodevelopmental outcome.

    This study compared two methods of holding preterm infants: 1) the kangaroo, or skin-to-skin method (K) and 2) the traditional method, or normal handling (T). Skin temperature, heart rate, respiratory rate and oxygen saturation were monitored during both the kangaroo and the traditional handling methods. After testing with the two methods, the mothers indicated their satisfaction and preference. Sixty-one pairs of mothers and babies were tested once with the K method and once with the T method. The first method tested was determined at random: 50% began with K and 50% with T. Skin temperature, heart rate and respiratory rate were similar with both K and T methods. Whereas oxygen saturation was significantly lower (92.8% vs 90.5%, p < 0.0001) under the T method, time of testing was longer (29.5 min vs 25.3 min, p = 0.02) for the K method than for T method. In summary, the findings suggested that mothers preferred the K method because the cold stress factor was avoided, oxygenation was better maintained, and mothers felt closer to their infants.

    AIM To analyze the low weight gain (WG) from birth to 4 and 6wk of life to predict the development of retinopathy of prematurity (ROP) among very low birth weight (VLBW) preterm babies. METHODS Three hundred and three newborns with VLBW were analyzed. Body weight measurements were recorded weekly. In all patients, the proportion of the WG was defined as the preterm weight measured at the 4th and 6th weeks of life minus the birth weight (BW) divided by the BW. Other risk factors for ROP were also analyzed. RESULTS Mean gestational age and mean BW of the whole cohort were 29.56±1.44wk and 1270.58±176.18g respectively. WG proportion at 4wk postnatal age (18.89%±13.58%) were significantly lower in infants with ROP (P=0.003). WG proportion at 6wk was not different between ROP and no ROP group (42.48%±20.36% vs 46.43%±15.65% P=0.118). When all the other risk factors significant for ROP were included in the logistic regression poor WG did not arise as an independent risk factor. Area under the ROC curve was 0.591 (95%CI: 0.515-0.666; P=0.016). For ROP, the best discriminative cutoff of 18.06% of the proportional WG at the 4th week over the BW, sensitivity and specificity values were 67.3% and 50.0% respectively. CONCLUSION Low WG proportion in the first 4wk of life is maybe an additional predictor of ROP in very low BW infants. Preterm babies with low BW and low WG proportion should be followed closely for ROP. PMID:26682174

    Periodontitis is a destructive inflammatory disease of the supporting tissues of the teeth and is caused by specific microorganisms or group of specific microorganisms. The association of periodontal infection with organ systems like cardiovascular system, endocrine system, reproductive system, and respiratory system makes periodontal infection a complex multiphase disease. Inflamed periodontal tissues produce significant amounts of proinflammatory cytokines, mainly interleukin 1-beta (IL-1β), IL-6, prostaglandin E2, and tumor necrosis factor-alpha (TNF-α), which may have systemic effects on the host. Low birth weight, defined as birth weight less than 2,500 g, continues to be a significant public health issue in both developed and developing countries. Research suggests that the bacteria that cause inflammation in the gums can actually get into the bloodstream and target the fetus, potentially leading to premature labor and low-birth-weight (PLBW) babies. One reasonable mechanism begins with deleterious effects of endotoxins released from Gram-negative bacteria responsible for periodontal disease. Hence periodontal disease appears to be an independent risk factor for PLBW and there is a need to expand preventive measures for pregnant women in harmonization with the gynecological and dental professions.

    Germinal matrix hemorrhage (GMH) is a major cause of brain damage in prematurity and has long-lasting neurological implications. The development of brain inflammation contributes to brain injury, leading to a lifetime of neurologic deficits. PAR-1 and 4 receptors are involved with inflammatory pathways after brain hemorrhage in adult models of stroke, of which cyclooxygenase-2 (COX-2) is a potential mediator. We therefore hypothesized a role for PAR-1, 4/ COX-2 signaling following GMH. Postnatal day 7 Sprague-Dawley rats were subjected to GMH induction, which entailed stereotactic collagenase infusion into the ganglionic eminence. Animals were euthanized at two time points: 72 h (short-term) or 4 weeks (long-term). Short-term COX-2 expression was evaluated in the context of PAR-1 (SCH-79797) and PAR-4 (P4pal10) inhibition. Pups in the long-term group were administered the selective COX-2 inhibitor (NS-398); and the neurobehavioral and pathological examinations were performed 4 weeks later. Pharmacological PAR-1, 4 antagonism normalized COX-2 expression following GMH and reduced hydrocephalus. Early inhibition of COX-2 by NS-398 improved long-term neurobehavioral outcomes. COX-2 signaling plays an important role in brain injury following neonatal GMH, possibly through upstream PAR-1, 4 receptor mechanisms. PMID:26463949

    Objective: This study was designed to compare the efficacy and safety of enteral supplementation of a prebiotic mixture (SCGOS/LCFOS) on faecal microbiota in very premature infants who fed exclusively with human-milk. Methods: This double-center randomized control trial was conducted from December 2012 to November 2013 in the tertiary Neonatal Intensive Care Units of the Isfahan University of Medical Sciences. Fifty preterm infants (birth weight ≤1500 g who were not fed with formula) were randomly allocated to have enteral (tube feeding) supplementation with a prebiotic mixture (SCGOS/LCFOS; 9:1) or receive no prebiotics. Findings: The primary outcome (e.g., the effect of the prebiotic mixture on fecal microbiota pattern) was clearly different between the two groups. Despite greater coliforms colony counts in first stool cultures in the prebiotic group (Group P) (P = 0.67), coliforms were significantly lower in the third stool cultures in the Group P (P < 0.001). Furthermore, despite the much higher Lactobacillus colony counts, in the first stool cultures, in the control group (Group C) (P = 0.005); there was a trend toward significantly increased Lactobacillus colony counts in the Group P during the study, but the difference between Lactobacillus colony counts, in the third stool cultures, between two groups was no longer statistically significant (P = 0.11). Interestingly, the median length of hospital stay was significantly less in the Group P (16 [12.50–23.50] vs. 25 [19.50–33.00] days; P = 0.003). Conclusion: This suggests that it might have been “the complete removal of formula” which manifests a synergistic effect between nonhuman neutral oligosaccharides (prebiotics) and human oligosaccharides, which in turn, led to the rapid growth of beneficial Lactobacillus colonies in the gut of breast milk-fed preterm infants, while decreasing the number of pathogenic coliforms microorganisms. Therefore, further studies with larger sample sizes are

    Premature infants born at 30 weeks' gestational age or younger, or 1500 g or smaller, are screened for retinopathy of prematurity (ROP). Guidelines for supplemental oxygen in neonatal intensive care units have decreased but not eliminated the incidence of severe ROP. The underlying cause for ROP is prematurity and low birth weight, and with the survival of smaller and younger babies, ROP continues to be a significant problem facing premature infants. Threshold ROP is treated with retinal photocoagulation, but newer treatments such as intraocular injections of bevacizumab (Avastin) are being used alone or in conjunction with laser. PMID:24852153

    Indirect inguinal hernia is the most common congenital anomaly in the pediatric age group. About 15-20% of hernias in infant girls contain ovary, sometimes with a Fallopian tube. The presence of the uterus incarcerated with the adnexa is a very unusual occurrence in female infants with normal kariotype and phenotype, being commonly associated with several disorders of sex development. The surgical repair of this form of hernia is more difficult than a common herniorrhaphy because of the adhesions between the organs and the wall of the sac and the risk of damage during their freeing. We present a rare case of irreducible indirect inguinal hernia containing uterus and bilateral adnexa (fallopian tubes and ovaries) in a premature female infant, discussing the etiopathogenesis and the surgical features of this disorder.

    A prospective, double-blind, controlled trial was conducted to determine whether instillation of an exogenous surfactant into the lungs before the first breath could prevent hyaline membrane disease. The surfactant is calf lung lipid extracted from saline lung lavage. Entry was limited to infants who were 24 to 28 weeks' gestation, who were born at Children's Hospital of Buffalo, and whose mothers had not received betamethasone for more than 24 hours before birth. Treated infants received 3 mL (90 mg) of calf lung surfactant extract instilled into their trachea before the first breath; control infants received 3 mL of normal saline. A prospective scoring system and respiratory support variables were used to compare the groups. At 48 hours of age, only two of 14 calf lung surfactant extract-treated infants (14%) had hyaline membrane disease compared with seven of 13 control infants (54%) (P = .033). Inspired oxygen, mean airway pressure, ventilator rate and ventilator efficiency index were also lower in the treated group during the first 48 hours of life (P less than .01 to P less than .001). Calf lung surfactant extract instillation at birth appears to be an effective material and method of preventing hyaline membrane disease in extremely premature infants. PMID:3900906

    Introduction: Nowadays particular emphasis is placed on the developmental aspects of premature infants care. Massage therapy is one of the best-known methods of caring. Due to the minimal touch policy in neonatal intensive care units (NICUs), massaging is not usually performed on premature infants. However, there is not sufficient evidence to support the claim that newborn infants with complex medical conditions should not be massaged. This study aimed to determine the effects of massage with coconut and sunflower oils on oxygen saturation of infants with respiratory distress syndrome (RDS) treated with nasal continuous positive airway pressure (NCPAP). Methods: This was a randomized controlled trial on 90 newborns who were admitted to Alzahra Hospital (Tabriz, Iran). The infants were divided into control and massage therapy groups (massage with coconut and sunflower oils). Data was collected using a hospital documentation form. A 15-minute daily massage was performed for 3 days. Respiratory rate (RR), fraction of inspired oxygen (FiO2) and oxygen saturation were measured 5 minutes before the massage, 3 times during the massage, and 5 minutes after the massage. The collected data was analyzed using a mixed model. Results: In comparison to coconut oil and control groups, mean oxygen saturation of sunflower oil group was improved. In addition, the coconut massage group showed lower oxygen saturation than the control group but was all values were within the normal range. Although massage decreased oxygen saturation, there was no need to increase FiO2. Conclusion: Massage therapy can provide developmental care for infants treated with NCPAP. PMID:25276695

    Introduction There is new emphasis on identifying and treating HIV in the first days of life and also an appreciation that low birth weight (LBW) and preterm delivery (PTD) frequently accompany HIV-related pregnancy. Even in the absence of HIV, PTD and LBW contribute substantially to neonatal and infant mortality. HIV-exposed and -infected infants with these characteristics have received little attention thus far. As HIV programs expand to meet the 90-90-90 target for ending the HIV pandemic, attention should focus on newborn infants, including those delivered preterm or of LBW. Discussion In high prevalence settings, infant diagnosis of HIV is usually undertaken after the neonatal period. However, as in utero infection may be diagnosed at birth, earlier initiation of therapy may limit viral replication and prevent early damage. Globally, there is growing awareness that preterm and LBW infants constitute a substantial proportion of births each year. Preterm infants are at high risk for vertical transmission. Feeding difficulties, apnoea of prematurity and vulnerability to sepsis occur commonly. Feeding intolerance, a frequent occurrence, may compromise oral administration of medications. Although there is growing experience with post-exposure prophylaxis for HIV-exposed term newborn infants, there is less experience with preterm and LBW infants. For treatment, there are even fewer options for preterm infants. Only zidovudine has adequate dosing recommendations for treating term and preterm infants and has an intravenous formulation, essential if feeding intolerance occurs. Nevirapine dosing for prevention, but not treatment, is well established for both term and preterm infants. HIV diagnosis at birth is likely to be extremely stressful for new parents, more so if caring for preterm or LBW infants. Programs need to adapt to support the medical and emotional needs of young infants and their parents, where interventions may be lifesaving. Conclusions New focus is

    The aim of the present study was to investigate the efficacy of L-carnitine therapy on the occurrence and prognosis of respiratory distress syndrome (RDS). A single blind, randomized controlled trial study was conducted on 130 infants with gestational ages of 28–36 weeks. Infants were assigned to experimental groups (groups 1 and 2) and control groups (groups 3 and 4). Groups 1 and 3 consisted of infants with RDS, and groups 2 and 4 groups were composed of infants without RDS. The experimental groups were treated with carnitine. No statistically significant differences in serum carnitine levels were detected between the study and the control groups on day 1 of treatment (P=0.06). However, on day 7 of treatment, serum carnitine levels in the experimental groups were significantly increased (P=0.02), as compared with the control groups. The surfactant requirement value, which is how many rounds of surfactant therapy were required, was 1.56±0.97 in group 1, and 2.12±0.99 in group 3 (P<0.001). The mean duration of mechanical ventilation required was 3.04±3.60 days in group 1, and 4.73±5.63 days in group 3 (P<0.001). The present results indicate that carnitine supplementation in premature infants with RDS may help to increase carnitine levels, thus decreasing the duration of mechanical ventilation and surfactant requirement.

    Aim: The study explored fathers’ experience of premature birth during the hospitalization of their infants, analyzing levels of depressive and anxiety symptoms as compared with mothers. Moreover the Italian version of the Clinical Interview for Parents of High-Risk Infant (CLIP) was tested through confirmatory factor analysis. Methods: Couples of parents (N = 64) of preterm infants (gestational age < 37 weeks) were administered a socio-demographic questionnaire, the Edinburgh Postnatal Depression Scale, the State-Trait Anxiety Inventory and the CLIP after the admission to the Neonatal Intensive Care Unit (NICU). Results: Significant levels of anxiety and depressive symptoms and high percentages of subjects above the corresponding risk thresholds were found among fathers and mothers with higher scores among the latters. Confirmatory factor analysis of the CLIP showed an adequate structure, with better fit for mothers than for fathers. Conclusion: Results highlighted the importance for nurses and clinicians working in the NICU to consider not only the maternal difficulties but also the paternal ones, even if these are often more hidden and silent. In addition the CLIP may be considered an useful interview for research and clinical purposes to be used with parents of high-risk infants. PMID:26483712

    Apnea of prematurity is one of the most common diagnoses in the NICU. Despite the frequency of apnea of prematurity, it is unknown whether recurrent apnea, bradycardia, and hypoxemia in preterm infants are harmful. Research into the development of respiratory control in immature animals and preterm infants has facilitated our understanding of the pathogenesis and treatment of apnea of prematurity. However, the lack of consistent definitions, monitoring practices, and consensus about clinical significance leads to significant variation in practice. The purpose of this clinical report is to review the evidence basis for the definition, epidemiology, and treatment of apnea of prematurity as well as discharge recommendations for preterm infants diagnosed with recurrent apneic events.

    Fetuses as early as 15 weeks' gestation exhibit rhythmical respiratory movements shown by real-time ultrasonography. The nucleus/tractus solitarius is the principal brainstem respiratory center; other medullary nuclei also participate. The purpose was to determine temporal maturation of synaptogenesis. Delayed synaptic maturation may explain neurogenic apnea or hypoventilation of prematurity and some cases of sudden infant death syndrome. Sections of medulla oblongata were studied from 30 human fetal and neonatal brains 9 to 41 weeks' gestation. Synaptophysin demonstrated the immunocytochemical sequence of synaptogenesis. Other neuronal markers and myelin stain also were applied. The nucleus/tractus solitarius was similarly studied in fetuses with chromosomopathies, metabolic encephalopathies, and brain malformations. Synapse formation in the nucleus solitarius begins at about 12 weeks' gestation and matures by 15 weeks; myelination initiated at 33 weeks. Synaptogenesis was delayed in 3 fetuses with different conditions, but was not specific for only nucleus solitarius. Delayed synaptogenesis or myelination in the nucleus solitarius may play a role in neonatal hypoventilation, especially in preterm infants and in some sudden infant death syndrome cases.

    Very low birth weight (VLBW) infants of higher (n = 18) and lower (n = 29) perinatal biological risk were contrasted at 4 months adjusted age with healthy full-term infants (n = 32) in their arousal during a standardized peekaboo game with an examiner. VLBW infants showed less positive arousal, more negative arousal, and 3 mixtures of behavioral cues across the peekaboo game seldom seen for full-term infants-strong cues of both positive and negative arousal, strong cues of negative arousal alone, and no strong cues of either positive or negative arousal. Contrary to expectations, perinatal biological risk did not strongly predict variations in arousal within the VLBW group. Possible changes in how internal and external sources of arousal are integrated provide one explanation for the presence of strong relationships between perinatal biological risk and social responsiveness near term age and their disappearance by 4 months of age.

    In October 2014, a hospital in Connecticut notified CDC and the Connecticut Department of Public Health of a fatal case of gastrointestinal mucormycosis in a preterm infant. The infant, born at 29 weeks' gestation and weighing 1,400 grams (about 3 pounds), had developed signs and symptoms initially consistent with necrotizing enterocolitis approximately 1 week after birth. Exploratory laparotomy revealed complete ischemia of the gastrointestinal tract from the esophagus to the rectum; a portion of necrotic cecum was sent for microscopic examination. Following surgery, the infant developed multiple areas of vascular occlusion, including a large clot in the aorta, findings not usually associated with necrotizing enterocolitis. The infant died soon after. Histopathology results from the resected cecum revealed an angioinvasive fungal infection consistent with mucormycosis. Gastrointestinal mucormycosis is an extremely rare fungal infection caused by mold in the order Mucorales. It occurs predominantly in low birth weight infants, patients with diarrhea and malnutrition, and those receiving peritoneal dialysis; mortality is 85%. Local investigation revealed that the infant had received a dietary supplement, ABC Dophilus Powder, for 7 days, beginning on day 1 of life. PMID:25695322

    The pacemaking system of the heart is complex; a healthy heart constantly integrates and responds to extracardiac signals, resulting in highly complex heart rate patterns with a great deal of variability. In the laboratory and in some pathological or age-related states, however, dynamics can show reduced complexity that is more readily described and modeled. Reduced heart rate complexity has both clinical and dynamical significance -- it may provide warning of impending illness or clues about the dynamics of the heart's pacemaking system. Here we describe uniquely simple and interesting heart rate dynamics observed in premature human infants - reversible transitions to large-amplitude periodic oscillations. We propose a mathematical interpretation based on Hopf bifurcation theory.

    The improved survival of extremely premature infants has generated intense interest in the quality of life of the survivors. This review focuses on the major long-term complications of prematurity (developmental disability, retinopathy of prematurity, chronic lung disease) and concludes with an overview of the broader spectrum of morbidity. Severe impairment (cerebral palsy, mental retardation, retrolental fibroplasia, severe chronic lung disease) fortunately occurs in a small proportion of survivors. However, the prevalence of the lesser morbidities (minimal cerebral dysfunction/learning disability, poor growth, postneonatal illnesses, rehospitalization) is less clearly defined. These problems all have an impact on families, and on medical and educational services. PMID:2935764

    With the development and routine use of real-time ultrasound scanning, it has been possible to collect 20 autopsy cases of infants in whom the ultrasound scan was first normal and then showed evidence of subependymal/intraventricular hemorrhage (SEH/IVH). Analysis of these cases with known postnatal origin of the hemorrhage permitted the development for the first time of a time scale to characterize the temporal evolution of the histopathologic reactions to hemorrhage in the premature human brain. This time scale was then used to define the histologic stage of the lesions in 27 other cases of infants who had a scan demonstrating SEH/IVH prior to death but who had not a previously normal scan. Only 2 cases were found to lie off the original scale, indicating a prenatal onset of the hemorrhage in about 5% of the total cases. Thus, postnatal events immediately preceding the onset of the hemorrhage are more likely to be implicated in the pathogenesis of SEH/IVH than prenatal or obstetric events. Comparison with similar reactions in the adult indicate that the early reactions by macrophages occur at about the same rate but the routine transfer of iron from macrophages to astrocytes and the much slower rate of absorption to form a cyst in the adult combine to form a complicated pattern that requires a different set of criteria for the intermediate and late stages in the adult.

    Very low birth weight (VLBW) infants have ophthalmologic examinations for retinopathy of prematurity (ROP) prior to discharge, with appropriate follow-up and intervention where appropriate. Eye drops such as cylopentolate, tropicamide, and phenylephrine are used at different concentrations to provide proper pupil dilation for screening ROP. Topical instillation of eye drops may cause mild or severe ocular or systemic adverse effects. Early recognition of systemic toxicity after eye drop instillation is important. The authors present a case of a VLBW infant who developed significant abdominal symptoms (mimicking ileus) that were significant enough to discontinue oral feeding after ocular instillation of 0.5% tropicamide and 2.5% phenylephrine eye drops for routine examination of ROP. After structural and functional gastrointestinal disorders and sepsis were excluded, symptoms resolved completely after discontinuation of the drug. This report is thought to be the first in the medical literature to address 5% tropicamide and 2.5% phenylephrine eye drops, and the combination that may lead to serious complication after ROP examinations.

    Supplemental oxygen contributes to the development of bronchopulmonary dysplasia (BPD) in premature infants. In this investigation, we tested the hypothesis that prenatal treatment of pregnant mice (C57BL/6J) with the cytochrome P450 (CYP)1A1 inducer, ss-napthoflavone (BNF), will lead to attenuation of lung injury in newborns (delivered from these dams) exposed to hyperoxia by mechanisms entailing transplacental induction of hepatic and pulmonary CYP1A enzymes. Pregnant mice were administered the vehicle corn oil (CO) or BNF (40 mg/kg), i.p., once daily for 3 days on gestational days (17-19), and newborns delivered from the mothers were either maintained in room air or exposed to hyperoxia (> 95% O{sub 2}) for 1-5 days. After 3-5 days of hyperoxia, the lungs of CO-treated mice showed neutrophil infiltration, pulmonary edema, and perivascular inflammation. On the other hand, BNF-pretreated neonatal mice showed decreased susceptibility to hyperoxic lung injury. These mice displayed marked induction of ethoxyresorufin O-deethylase (EROD) (CYP1A1) and methoxyresorufin O-demethylase (MROD) (CYP1A2) activities, and levels of the corresponding apoproteins and mRNA levels until PND 3 in liver, while CYP1A1 expression alone was augmented in the lung. Prenatal BNF did not significantly alter gene expression of pulmonary NAD(P)H quinone reductase (NQO1). Hyperoxia for 24-72 h resulted in increased pulmonary levels of the F{sub 2}-isoprostane 8-iso-PGF{sub 2{alpha}}, whose levels were decreased in mice prenatally exposed to BNF. In conclusion, our results suggest that prenatal BNF protects newborns against hyperoxic lung injury, presumably by detoxification of lipid hydroperoxides by CYP1A enzymes, a phenomenon that has implications for prevention of BPD in infants. - Highlights: > Supplemental oxygen is routinely administered to premature infants. > Hyperoxia causes lung injury in experimental animals. > Prenatal treatment of mice with beta-naphthoflavone attenuates oxygen

    Objective To compare the efficacy and safety of a new porcine-derived pulmonary surfactant developed by Instituto Butantan with those of animal-derived surfactants commercially available in Brazil, regarding neonatal mortality and the major complications of prematurity in preterm newborns with birth weight up to 1500g and diagnosed with respiratory distress syndrome. Methods Neonates diagnosed with respiratory distress syndrome were randomized to receive either Butantan surfactant (Butantan group) or one of the following surfactants: Survanta® or Curosurf®. Newborns receiving Survanta® or Curosurf® comprised the control group. The main outcome measures were mortality rates at 72 hours and at 28 days of life; the typical complications of prematurity as evaluated on the 28th day of life were defined as secundary outcomes. Results No differences were observed between the Butantan (n=154) and control (n=173) groups in relation to birth weight, gestational age, sex, and prenatal use of corticosteroids, or in mortality rates both at 72 hours (14.19% versus 14.12%; p=0.98) and at 28 days (39.86% versus 33.33%; p=0.24) of life. Higher 1- and 5-minute Apgar scores were observed among control group newborns. No differences were observed as regards the secondary outcomes, except for greater need for supplemental oxygen and a higher incidence of interstitial pulmonary emphysema in the Butantan group. Conclusion The mortality rates at 72 hours and 28 days of life and the incidence of major complications of prematurity were comparable to those found with the animal-derived surfactants commercially available in Brazil, showing the efficacy and safety of the new surfactant in the treatment of respiratory distress syndrome in newborns.

    Fluid and electrolyte maintenance in very low birth weight infants during the first week of life must be adapted to their physiological characteristics and to pathological events. Insensible water losses are elevated and may reach 100 mL/kg/24 h depending upon many factors, such as type of incubator, phototherapy, presence of respiratory distress syndrome, changes in transepidermal water losses and renal water and electrolyte regulation (prediuretic, diuretic and postdiuretic phases); there is also a major risk of hypernatremia and hyperkaliema. In cases of insufficient fluid intake the main complication is dehydration with hypernatremia. Excessive fluid intake results in increased incidence of bronchopulmonary dysplasia, patent ductus arteriosus and necrotizing enterocolitis. Hypernatremia is a major risk factor of intracranial hemorrhage. A careful management of water and electrolyte requirements is therefore mandatory in very low birth weight infants. Guidelines on daily maintenance and management are presented. PMID:9239273

    The aim of this study was to validate the efficacy of a protocol for the management of infants born to colonised mothers with Group B Streptococcus (GBS). We studied a cohort of newborns admitted at the A. Gemelli University Hospital between May 2006 and December 2009. A total of 1,108 were newborns of mothers with GBS; 178 were children of mothers with unknown GBS status. Newborns were managed according to the care protocol in use at our division. Infected infants were born to mothers who underwent inadequate intrapartum antibiotic prophylaxis (IAP). No mother with complete IAP had an infected newborn. The incidence of invasive GBS infection in newborns of mothers with GBS was 0.4% and in newborns of mothers with unknown GBS status was 2.2%. Only 17.4% of newborns of mothers with GBS had risk factors. The complete IAP should always be performed regardless of the presence or the absence of risk factors. The care protocol applied offers successful management of the newborns of mothers with GBS, based on the correct execution of IAP, considering as a primary risk factor, the gestational age of < 35 weeks.

    Abstract Objective Our objective was to investigate key factors in promoting skin-to-skin contact (STSC) in the neonatal intensive care unit (NICU). Methods As part of a California Perinatal Quality Care Collaborative on improving nutrition and promoting breastmilk feeding of premature infants, a multidisciplinary group of representatives from 11 hospitals discussed the progress and barriers in pursuing the project. A key component of the collaborative project was promotion of STSC. Sessions were audio-recorded, transcribed, and assessed using qualitative research methods with the aid of Atlas Ti software (ATLAS.ti Scientific Software Development GmbH, Berlin, Germany). Two primary investigators studied the transcripts for themes related to STSC. Using an iterative approach, selected themes were explored, and representative quotes were selected. Results Barriers to promoting STSC fell into broad themes of implementation, institutional, and familial factors. The main challenge identified in implementation was defining a clinically stable eligible population of patients. Key institutional factors were education and motivation of staff. Familial factors involved facilitation and sustained motivation of mothers. In response to these barriers, opportunities for promoting STSC were enacted or suggested by the group, including defining clinical stability for eligibility, facilitating documentation, strategies to increase parent and staff education and motivation, and encouraging maternal visitation and comfort. Conclusions Our findings may be useful for institutions seeking to develop policies and strategies to increase STSC and breastmilk feeding in their NICUs. PMID:22011130

    PurposeTo evaluate the serial changes in retinal vasculature in infants treated with intravitreal bevacizumab (IVB) for aggressive posterior retinopathy of prematurity (APROP) in zone I.MethodsRetrospective analysis of serial changes in retinal vasculature after IVB in the seven eyes of four babies with APROP in zone I.ResultsThe initial regression, following IVB, was dramatic with reduction in vessel caliber and marked thinning and invisibility of the bridging shunts. Resurgent vascular development was very slow radially though there was continued abnormal vascular growth circumferentially. Common findings in all eyes were tangled vasculature and fine saw-toothed shunts. The variable findings were (1) new closely packed multilayered bridging shunts, long arching mature looking vessels, and finally a ridge at the periphery (n=3 eyes) at 52 weeks of postmenstrual age (PMA); (2) status quo at the stage of saw-toothed shunt and ridge in both eyes for a long time (n=2 eyes); and (3) multiple retinal hemorrhages within the vascularized retina and thick preretinal hemorrhage overlying the saw-toothed shunts and ridge that persisted for another 3 weeks and regressed 2 weeks after laser (n=1). The eyes that received bevacizumab alone (3) did not show any abnormal vascularization at 56 weeks of PMA or beyond.ConclusionsThe retinal vascularization following IVB was different than normal in terms of its time, speed, and morphology; few of these changes are first to be reported in the literature (Medline search) and warrants further studies.

    Premature menopause affects 1% of women under the age of 40 years. The women are at risk of premature death, neurological diseases, psychosexual dysfunction, mood disorders, osteoporosis, ischemic heart disease and infertility. There is need to use simplified protocols and improved techniques in oocyte donation to achieve pregnancy and mother a baby in those women at risk. Review of the pertinent literature on premature menopause, selected references, internet services using the PubMed and Medline databases were included in this review. In the past, pregnancy in women with premature menopause was rare but with recent advancement in oocyte donation, women with premature menopause now have hoped to mother a child. Hormone replacement therapy is beneficial to adverse consequences of premature menopause. Women with premature menopause are at risk of premature death, neurological diseases, psychosexual dysfunction, mood disorders, osteoporosis, ischemic heart disease and infertility. Public enlightenment and education is important tool to save those at risk. PMID:23634337

    More than 500,000 premature infants are born in the United States every year. Preterm birth results in a multitude of negative adverse outcomes for children, including extended stays in the neonatal intensive care unit (NICU), developmental delays, physical and mental health/behavioral problems, increased medical utilization, and poor academic performance. In addition, parents of preterms experience a higher incidence of depression and anxiety disorders along with altered parent-infant interactions and overprotective parenting, which negatively impact their children. The costs associated with preterm birth are exorbitant. In 2005, it is estimated that preterm birth cost the United States $26.2 billion. The purpose of this study was to perform a cost analysis of the Creating Opportunities for Parent Empowerment (COPE) program for parents of premature infants, a manualized educational-behavioral intervention program comprising audiotaped information and an activity workbook that is administered to parents in 4 phases, the first phase commencing 2 to 4 days after admission to the NICU. Findings indicated that the COPE program resulted in cost savings of at least $4864 per infant. In addition to improving parent and child outcomes, routine implementation of COPE in NICUs across the United States could save the healthcare system more than $2 billion per year. PMID:19092521

    Preterm delivery (<37 wks post-menstrual age) is associated with suboptimal bone mass. We hypothesized that tactile/kinesthetic stimulation (TKS), a form of infant massage that incorporates kinesthetic movement, would increase bone strength and markers of bone accretion in preterm infants. Preterm, AGA infants (29-32 wks) were randomly assigned to TKS (N=20) or Control (N=20). Twice daily TKS was provided six days per week for two weeks. Control infants received the same care without TKS treatment. Treatment was masked to parents, health care providers, and study personnel. Baseline and week two measures were collected for tibial speed of sound (tSOS, m/sec), a surrogate for bone strength, by quantitative ultrasound (Sunlight8000) and urine markers of bone metabolism, pyridinium crosslinks and osteocalcin (U-MidOC and unOC). Infant characteristics at birth and study entry as well as energy/nutrient intake were similar between TKS and Control. TKS intervention attenuated the decrease in tSOS observed in Control infants (p<0.05). Urinary pyridinium crosslinks decreased over time in both TKS and CTL (p<0.005). TKS infants experienced greater increases in urinary osteocalcin (U-MidOC, p<0.001 and unOC, p<0.05). We conclude that TKS improves bone strength in premature infants by attenuating the decrease that normally follows preterm birth. Further, biomarkers of bone metabolism suggest a modification in bone turnover in TKS infants in favor of bone accretion. Taken together, we speculate that TKS improves bone mineralization.

    This longitudinal study reported the mid- and long-term neurodevelopmental outcome of 166 premature infants born with an extremely low birth weight (<1,000 g), all small for gestational age (<10th percentile birth weight for gestational age). Nine girls were lost to follow-up before 3 years of age, and 6 children were excluded a posteriori because of specific conditions diagnosed in the 1st year of life (severe abnormalities in 5). Of the remaining 151 children, 2% had cerebral palsy, 15% had lesser motor disturbances (reduced to 2% after psychomotor training), 8% had early severe developmental delays, and added mild and moderate delays and increasing cognitive gaps amounted to 28% in the 14th year. Visual deficits increased with age up to 63% of the older children. Seven children had deafness and 13 had hearing losses after otitis media. Language delays were observed at some stage in 31% of cases, as well as behavioral disturbances in 42% (severe problems in 12%). At last evaluation, 34% of the children were normal (12% of the older ones), 51% had minor deficiencies, 18% had moderate and 3% had major disabilities. Children entered the first grade in the 7th year in only 84% of cases, which dropped to 63% at proper level in the second grade; 47% entered high school at the proper age, 7/15 obtained the 'baccalauréat' in the 19th/20th year. The school performance was heavily dependent on the socioeconomic and cultural level of the family. PMID:12011568

  16. Genome resolved analysis of a premature infant gut microbial community reveals a Varibaculum cambriense genome and a shift towards fermentation-based metabolism during the third week of life

    PubMed Central

    2013-01-01

    Background The premature infant gut has low individual but high inter-individual microbial diversity compared with adults. Based on prior 16S rRNA gene surveys, many species from this environment are expected to be similar to those previously detected in the human microbiota. However, the level of genomic novelty and metabolic variation of strains found in the infant gut remains relatively unexplored. Results To study the stability and function of early microbial colonizers of the premature infant gut, nine stool samples were taken during the third week of life of a premature male infant delivered via Caesarean section. Metagenomic sequences were assembled and binned into near-complete and partial genomes, enabling strain-level genomic analysis of the microbial community. We reconstructed eleven near-complete and six partial bacterial genomes representative of the key members of the microbial community. Twelve of these genomes share >90% putative ortholog amino acid identity with reference genomes. Manual curation of the assembly of one particularly novel genome resulted in the first essentially complete genome sequence (in three pieces, the order of which could not be determined due to a repeat) for Varibaculum cambriense (strain Dora), a medically relevant species that has been implicated in abscess formation. During the period studied, the microbial community undergoes a compositional shift, in which obligate anaerobes (fermenters) overtake Escherichia coli as the most abundant species. Other species remain stable, probably due to their ability to either respire anaerobically or grow by fermentation, and their capacity to tolerate fluctuating levels of oxygen. Metabolic predictions for V. cambriense suggest that, like other members of the microbial community, this organism is able to process various sugar substrates and make use of multiple different electron acceptors during anaerobic respiration.

    To describe the characteristics of infants with bilateral Stage 4b or 5 ROP (i.e. with subtotal or total retinal detachment) who presented to eye departments in two major cities in Mexico, to identify reasons why they may have become blind in order to recommend how programs could be improved. A large case-series of infants with Stage 4b or 5 ROP in both eyes confirmed by ultrasound who attended the ROP Clinic, Hospital Civil de Guadalajara from September 2010 to November 2012, and the Department of Ophthalmology, Hospital Infantil de Mexico Federico Gomez from December 2011 to December 2012 were identified from the diagnostic databases of each hospital. Mothers of infants in Guadalajara had a telephone interview. 89/94 eligible infants were included in the study, 48 in Guadalajara and 41 in Mexico City. Cases came from 22 of the 32 states in Mexico. Half of the infants attending Guadalajara 24/48 (50 %) had been cared for in NICUs without ROP screening programs and were not examined. Among the 24 infants cared for in NICUs with ROP programs, 7/24 (29.1 %) mothers reported that their infant had not been examined while in the NICU, and a further 9/24 (37.5 %) were either not referred for screening after discharge or they did not attend. Two infants had failed laser treatment. Strategies and resources to prevent end stage ROP have not been firmly established in Mexico. There is an urgent need to expand the coverage and quality of ROP programs, to ensure that existing screening guidelines are better adhered to, and to improve communication with parents.

    Abstract Objective: Infants may benefit from early nutritional intervention to decrease hospital stay. To evaluate the effects of adding a human milk (HM)-derived cream (Cream) product to a standard feeding regimen in preterm infants. Materials and Methods: In a prospective multicenter randomized study, infants with birth weights 750–1,250 g were assigned to a Control or Cream group. The Control group received a standard feeding regimen consisting of mother's own milk or donor HM with donor HM-derived fortifier. The Cream group received the standard feeding regimen along with an additional HM-derived cream supplement when the HM they received was <20 kcal/oz. Primary outcomes of this secondary analysis included comorbidities, length of stay (LOS), and postmenstrual age (PMA) at discharge. Results: We enrolled 75 infants (Control n = 37, Cream n = 38) with gestational age 27.7 ± 1.8 weeks and birth weight 973 ± 145 g (mean ± SD). After adjusting for gestational age, birth weight, and presence of bronchopulmonary dysplasia (BPD), the Cream group had a decreased PMA at discharge (39.9 ± 4.8 versus 38.2 ± 2.7 weeks, p = 0.03) and LOS (86 ± 39 versus 74 ± 22 days, p = 0.05). For 21 infants with BPD, these values trended toward significance for PMA at discharge (44.2 ± 6.1 versus 41.3 ± 2.7 weeks, p = 0.08) and LOS (121 ± 49 versus 104 ± 23 days, p = 0.08). Conclusions: Very preterm infants who received an HM-derived cream supplement were discharged earlier. Infants with BPD may have benefited the most. PMID:26982282

    The objective of this study was to evaluate the predictive performance of 4 allometric models to predict clearance in pediatric ages ranging from premature neonates to children ≤2 years of age. Four allometric models were used to predict clearances of 28 drugs in children from preterm neonates to 2 years of age (n = 564). The 4 models are (1) basal metabolic rate-dependent model; (2) age-dependent exponent model; (3) an allometric model based on kidney and liver weights as well as kidney and liver blood flow; and (4) an allometric model based on a fixed exponent of 0.75. The predictive performance of these models was evaluated by comparing the predicted clearance of the studied drugs with the observed clearance in an individual child. The results of the study indicated that the 3 new proposed models predicted the mean clearance of the drugs with reasonable accuracy (≤50% prediction error). On the other hand, the exponent of 0.75 produced substantial prediction error. Predicted individual clearance values were ≥50% in approximately 30% of the children by the proposed 3 methods and 73% by exponent 0.75. The 3 new proposed allometric models can predict mean clearances of drugs in children from premature neonates to ≤2 years of age with reasonable accuracy and are of practical value during pediatric drug development.

    Interleukin-8 (IL-8), soluble intercellular adhesion molecule-1 (sICAM), elastase and neutrophils were assessed in bronchoalveolar lavage fluid from nine infants who developed chronic lung disease (CLD) after respiratory distress syndrome (RDS), seven who had recovered from RDS, and in four control infants. IL-8, sICAM, elastase and neutrophils in bronchoalveolar lavage fluid were increased in the CLD group, the differences being most pronounced at 10 days of age. When babies with and without CLD were compared at 10 days of age, bronchoalveolar lavage fluid from the babies with CLD had significantly increased IL-8 (114.0 vs 12.7 ng/ml), sICAM (19.0 vs 1.1 micrograms/ml), elastase (6.9 vs 0.9 micrograms/ml) and neutrophils (1.9 vs 0.4 x 10(9)/l). In serum the increased concentration of IL-8 observed at birth in the CLD (247 pg/ml) and RDS (192 pg/ml) groups decreased over three weeks to the concentrations observed in the controls (< 70 pg/ml). Persistent inflammation could be a major contributory factor in the development of CLD. PMID:7712280

    Poma, P. A.

    1996-01-01

    The management of patients with premature rupture of membranes has changed markedly in the past several years. The basis for this is a combination of a better understanding of newborn physiology, improved neonatal care, refinements in antibiotic therapy, and the widespread use of maternal and fetal monitoring. The best outcome for both mother and infant undoubtedly reflects data based on a combination of factors, among which are gestational age survival, evidence of fetal distress, presence or absence of labor and sepsis, and of course, the cervical condition as it is related to labor-readiness. An important recent advance is the recognition that an active observation management program is associated with less morbidity and mortality than the classic management course of delivery within 12 hours of membrane rupture. The fact that preterm premature rupture of membranes tends to recur in subsequent pregnancies offers an opportunity for prevention. Moreover, advances in perinatal and neonatal care will continue to improve the outcomes of these women and their children. PMID:8583489

    1982-12-01

    We have developed a classification system for the acute phases of retinopathy of prematurity based on more than 13,000 ophthalmoscopic examinations of more than 3,400 premature infants between 1968 and 1982. Two forms of the active disease exist. Retinopathy of prematurity is a relatively common mild disease and retinopathy of prematurity plus is characterized by rapid progression and posterior pole vascular tortuosity and dilation. The five grades progress from peripheral vascular abnormalities (Grade 1) through a demarcation line (Grade 2) and extraretinal neovascularization (Grade 3) to partial (Grade 4) or total (Grade 5) retinal detachment. The persistence of abnormal retinal vessels during the first year of life is considered "transitional" retinopathy of prematurity unless unequivocal cicatricial changes with macular distortion develop.

    The development of clinical practice guidelines involving multiple health care providers presents a challenge in the neonatal intensive care unit (NICU). Implementation and evaluation of the guideline is as important as the development of the guideline itself. We explored the use of a quality improvement approach in the implementation of a feeding framework. A Plan-Do-Study-Act (PDSA) quality improvement cycle model was used to implement and evaluate a stepwise oral infant feeding guideline with emphasis on parent and care provider satisfaction. Three PDSA cycles were conducted, with each cycle resulting in modifications to use of the framework and development of knowledge translation and parent education techniques and tools. A PDSA cycle approach can be used effectively in guideline implementation and evaluation involving multidisciplinary health care professionals. This is Part II of a two-part series. Part I introduced the concept of quality improvement and tools for advancing practice changes. PMID:22763248

    The objective of the present work was to study the function of the retrocochlear auditory pathway in the premature infants with intrauterine growth retardation (IGR) in comparison to that of the normotrophics of a similar gestational age during the third and sixth months of life by recording auditory steady-state responses (ASSR). The audiological examination by the method of auditory steady-state response (ASSR) involved 127 children at the 3d month of life and in 97 children at the 6th month of life. It was shown that the ASSR thresholds at certain frequencies during the 3d and 6th months of life of the children born after the 32d week of pregnancy were significantly higher than in the children born after 32 weeks gestation. The comparison of the two objective audiological methods, viz. distortion-product otoacoustic emission (DPOAE) and ASSR, indicates that both should be used to evaluate the hearing function during the third and sixth months of life to compensate for the discrepancy between the results obtained by either technique.

In infants born prior to 28 weeks of gestation, a hemodynamically-significant patent ductus arteriosus (PDA) can cause cardiovascular instability, exacerbate respiratory distress syndrome, prolong the need for assisted ventilation, and increase the risk of bronchopulmonary dysplasia, intraventricular hemorrhage, renal dysfunction, intraventricular hemorrhage, cerebral palsy, and mortality. In this article, we review the pathophysiology, clinical features, and assessment of hemodynamic significance, and provide a rigorous appraisal of the quality of evidence to support current medical and surgical management of PDA of prematurity. Cyclo-oxygenase inhibitors such as indomethacin and ibuprofen remain the mainstay of medical therapy for PDA, and can be used both for prophylaxis as well as rescue therapy to achieve PDA closure. Surgical ligation is also effective and is used in infants who do not respond to medical management. Although both medical and surgical treatment have proven efficacy in closing the ductus, both modalities are associated with significant adverse effects. Because the ductus does undergo spontaneous closure in some premature infants, improved and early identification of infants most likely to develop a symptomatic PDA could help in directing treatment to the at-risk infants and allow others to receive expectant management.

  12. Premature ejaculation

    Premature ejaculation (PE) is a common male sexual disorder. Recent normative data suggests that men with an intravaginal ejaculatory latency time (IELT) of less than 1 minute have “definite” PE, while men with IELTs between 1 and 1.5 minutes have “probable” PE. Although there is insufficient empirical evidence to identify the etiology of PE, there is limited correlational evidence to suggest that men with PE have high levels of sexual anxiety and inherited altered sensitivity of central 5-HT (5-hydroxytryptamine, serotonin) receptors. Pharmacological modulation of the ejaculatory threshold using off-label daily or on-demand selective serotonin re-uptake inhibitors is well tolerated and offers patients a high likelihood of achieving improved ejaculatory control within a few days of initiating treatment, consequential improvements in sexual desire and other sexual domains. Investigational drugs such as the ejaculo-selective serotonin transport inhibitor, dapoxetine represent a major development in sexual medicine. These drugs offer patients the convenience of on-demand dosing, significant improvements in IELT, ejaculatory control and sexual satisfaction with minimal adverse effects. PMID:19675782

    Lithium is widely used and the treatment of choice for patients with manic-depressive illness. For pregnant patients with manic-depressive illness, however, the use of lithium during the first trimester of pregnancy may present an increased risk for fetal maldevelopment. We have recently cared for several large-for-gestational-age, prematurely born infants whose mothers were treated with lithium throughout pregnancy. To determine whether maternal lithium use during pregnancy may predispose to the onset of premature labor and fetal macrosomia, we reviewed records from the International Register of Lithium Babies and from a cohort of manic-depressive pregnant women. More than one third (36%) of infants reported to the International Register were born prematurely, and 37% of the premature infants were large for gestational age; 15% of the term infants were born large for gestational age. In the cohort group, manic-depressive mothers who received lithium during pregnancy had a 2.5-fold higher incidence of premature births than manic-depressive pregnant patients who did not receive lithium treatment. The incidence of large-for-gestational-age births in lithium-treated women in the cohort was not different from that of the general population or from manic-depressive women not treated with lithium. In summary, an association between maternal lithium therapy and premature delivery is reported. We recommend that women receiving lithium therapy during pregnancy be closely monitored for the onset of premature labor. PMID:8515304

    Retinopathy of prematurity (ROP) remains a significant threat to vision for extremely premature infants despite the availability of therapeutic modalities capable, in most cases, of managing this disorder. It has been shown in many controlled trials that application of therapies at the appropriate time is essential to successful outcomes in premature infants affected by ROP. Bedside binocular indirect ophthalmoscopy has been the standard technique for diagnosis and monitoring of ROP in these patients. However, implementation of routine use of this screening method for at-risk premature infants has presented challenges within our existing care systems, including relative local scarcity of qualified ophthalmologist examiners in some locations and the remote location of some NICUs. Modern technology, including the development of wide-angle ocular digital fundus photography, coupled with the ability to send digital images electronically to remote locations, has led to the development of telemedicine-based remote digital fundus imaging (RDFI-TM) evaluation techniques. These techniques have the potential to allow the diagnosis and monitoring of ROP to occur in lieu of the necessity for some repeated on-site examinations in NICUs. This report reviews the currently available literature on RDFI-TM evaluations for ROP and outlines pertinent practical and risk management considerations that should be used when including RDFI-TM in any new or existing ROP care structure.

    PubMed

    Feldman, Ruth; Eidelman, Arthur I

    2007-04-01

    Relations between maternal postpartum behavior and the emergence of parent-infant relatedness as a function of infant autonomic maturity were examined in 56 premature infants (birthweight = 1000-1500 g) and 52 full-term infants. Maternal behavior, mother depressive symptoms, and infant cardiac vagal tone were assessed in the neonatal period. Infant-mother and infant-father synchrony, maternal and paternal affectionate touch, and the home environment were observed at 3 months. Premature birth was associated with higher maternal depression, less maternal behaviors, decreased infant alertness, and lower coordination of maternal behavior with infant alertness in the neonatal period. At 3 months, interactions between premature infants with their mothers and fathers were less synchronous. Interaction effects of premature birth and autonomic maturity indicated that preterm infants with low vagal tone received the lowest amounts of maternal behavior in the postpartum and the least maternal touch at 3 months. Infant-mother and infant-father synchrony were each predicted by cardiac vagal tone and maternal postpartum behavior in both the preterm and full-term groups. Among preterm infants, additional predictors of parent-infant synchrony were maternal depression (mother only) and the home environment (mother and father). Findings are consistent with evolutionary perspectives on the higher susceptibility of dysregulated infants to rearing contexts and underscore the compensatory mechanisms required for social-emotional growth under risk conditions for parent-infant bonding.

    Apnoea of prematurity (AOP) affects almost all infants born at <28 weeks gestation or with birth weight <1000 g. When untreated, AOP may be associated with negative outcomes. Because of these negative outcomes, effective treatment for AOP is an important part of optimising care of preterm infants. Standard treatment usually involves xanthine therapy and respiratory support. Cutting-edge work with stochastic vibrotactile stimulation and new pharmaceutical agents continues to expand therapeutic options. In this article, we review the pathophysiology of AOP, associated conditions and treatment options. PMID:27010019

    Advances in perinatal care allow survival of more extremely premature infants, but the implementation and continuation of intensive care may itself constitute an ethical dilemma, given the limited chances of intact survival among the patients most at risk. This paper discusses several key issues raised by the options that are under general consideration with reference to births of infants at the threshold of viability, in particular: the implications of making a distinction between extreme prematurity and other general medical situations that may involve decisions on ending support; the concrete nature of the restrictions on therapy in such patients interactions and the need for feedback between parents, medical staff and society.

    Premature ejaculation is the most common sexual dysfunction in men. Its prevalence rate in Europe and in United States is estimated to be between 20% and 30%. The diagnosis of premature ejaculation is based on three main criteria: increased intravaginal ejaculatory latency time (IELT), lack of control over ejaculation and interpersonal psychological disturbances. Premature ejaculation is classified as lifelong (primary) or acquired (secondary) and might be facilitated by chronic prostatitis, diabetes mellitus, hyperthyroidism, obesity. The exact etiology of the disease remains unclear, although 5-HT (5-hydroxytryptamine) receptors are known to have a significant role. The use of SSRIs (selective serotonine reuptake inhibitors) is old and efficient form of therapy for premature ejaculation. Other drugs like tramadol, clomipramine, local anaesthetics and PDE-5 (phosphodiesterase 5) inhibitors also have some efficacy in the treatment of premature ejaculation. To minimize adverse effects the "on demand" therapy is preferred to the daily treatment. Simple questionnaires for patients are used to assess treatment effects. PMID:22827115

  5. Effects of Prematurity on the Development of Contrast Sensitivity: Testing the Visual Experience Hypothesis

    2013-01-01

    In order to investigate the effects of visual experience on early visual development, the current study compared contrast sensitivity across infants born with different levels of moderate-to-late prematurity. Here the logic is that at any given postterm age, the most premature infants will have the oldest postnatal age. Given that postnatal age is a proxy for visual experience, the visual experience hypothesis predicts that infants who are more premature, yet healthy, should have higher sensitivity. Luminance (light/dark) and chromatic (red/green) contrast sensitivities (CS) were measured in 236 healthy infants (born −10 to +2 weeks relative to due date) between 5 and 32 weeks postterm age from due date and 8 to 38 weeks postnatal from birth date. For chromatic CS, we found clear evidence that infants who were most premature within our sample had the highest sensitivity. Specifically, 4 to 10 additional weeks of visual experience, by virtue of being born early, enhanced chromatic CS. For luminance CS, similar but weaker results were seen. Here, only infants with an additional 6 to 10 weeks of visual experience, and only at later age points in development, showed enhanced sensitivity. However, CS in preterm infants was still below that of fullterm infants with equivalent postnatal age. In sum, these results suggest that chromatic CS is influenced more by prematurity (and possibly visual experience) than is luminance CS, which has implications for differential development of Parvocellular and Magnocellular pathways.

    Apnea of prematurity (AOP) is a common problem affecting premature infants, likely secondary to a "physiologic" immaturity of respiratory control that may be exacerbated by neonatal disease. These include altered ventilatory responses to hypoxia, hypercapnia, and altered sleep states, while the roles of gastroesophageal reflux and anemia remain controversial. Standard clinical management of the obstructive subtype of AOP includes prone positioning and continuous positive or nasal intermittent positive pressure ventilation to prevent pharyngeal collapse and alveolar atelectasis, while methylxanthine therapy is a mainstay of treatment of central apnea by stimulating the central nervous system and respiratory muscle function. Other therapies, including kangaroo care, red blood cell transfusions, and CO(2) inhalation, require further study. The physiology and pathophysiology behind AOP are discussed, including the laryngeal chemoreflex and sensitivity to inhibitory neurotransmitters, as are the mechanisms by which different therapies may work and the potential long-term neurodevelopmental consequences of AOP and its treatment.

    Dapoxetine, a selective serotonin reuptake inhibitor, is the first oral pharmacological agent indicated for the treatment of men aged 18-64 years with premature ejaculation. In four randomized, double-blind, placebo-controlled, multicentre studies of 12-24 weeks' duration, oral dapoxetine 30 or 60 mg (administered as needed) was effective in the treatment of men with premature ejaculation, inducing significantly (p < 0.001) greater improvements from baseline than placebo in the primary efficacy endpoint (mean intravaginal ejaculatory latency time [IELT] or mean average IELT [defined as the average of IELT values over the previous 4 weeks], as measured by the female partner utilizing a stopwatch). For the most part, dapoxetine recipients achieved significantly better outcomes than placebo recipients with regard to the secondary endpoints, including the Premature Ejaculation Profile (PEP) domains and the Clinical Global Impression or Patient Global Impression ratings of change in premature ejaculation, across these clinical studies. The beneficial effects of dapoxetine therapy on the perceived control over ejaculation and satisfaction with sexual intercourse PEP domains were sustained in a 9-month noncomparative extension phase of two identical 12-week, double-blind studies. Oral dapoxetine therapy for up to 12 months was generally well tolerated in men with premature ejaculation, with the nature of treatment-emergent adverse events generally similar across the clinical studies and between dapoxetine and placebo.

    The study of preterm labor and prematurity, as with any medical science, has undergone a major transformation in its approach from an inevitable part of obstetrics with few answers to one in which science has led to knowledge and clinical intervention. Despite these advancements, understanding of preterm labor and prevention of prematurity is still limited. In the current review, we begin the discussion with fetal viability, first from a historical perspective and then from the understanding of this issue from a prospective of various professional organizations. We then present the scope of the problem of preterm birth from various countries including the discrepancy between the US and Europe. We continue with updates on extreme prematurity and outcomes with two longitudinal studies from the past 2 years. We further review available interventions for prematurity and discuss the use of antenatal corticosteroids. First, we examine their use in the context of professional recommendations and then examine the trajectory of their continued use in the late preterm period. We focus on a European-based trial with preliminary results and an ongoing American counterpart. The current knowledge of molecular mechanisms behind preterm labor is presented with a focus on the multiple etiologies of preterm labor, both known and presumed, with updates in the basic science realm. Furthermore, up-to-date studies on prediction of preterm birth and prematurity-related morbidity are presented. PMID:25300768

    The Rice Infant Sensorimotor Stimulation (RISS) treatment was given to 15 premature infants to determine effects on neurophysiological development. The mothers of the infants were trained to administer the treatment for 15 minutes, 4 times a day, for 1 month, beginning the day the infant arrived home from the hospital. When each infant in the study (15 experimental and 14 control) was 4 months postnatal age, he/she was examined by a pediatrician, a psychologist, and a pediatric nurse who had no knowledge of which infant was experimental or control. The results indicated the experimental infants made significant gains in neurological development (p less than .001), weight gain (p less than .04), and mental development (p less than .05). The findings of this research indicate that early and systematic stimulation of the nerve pathways of the skin and of the vestibular nerve cells can accelerate growth and development of premature infants.

    The skin of preterm infants varies considerably in its level of maturity. To understand skin absorption in premature infants better, we report a technique for the assessment of percutaneous absorption at various gestational and postnatal ages using stable, isotope-labeled (13C6) benzoic acid. Our results indicate that in the preterm infant, this method detects enhanced skin absorption in the first postnatal days, which declines over three weeks to that expected of a full-term infant. This approach also indicates an inverse relationship between gestational age and skin absorption, as well as postnatal age and skin absorption. The reported technique is a safe and noninvasive method using a model skin penetrant for the study of percutaneous absorption in preterm infants from which basic data may be derived to add to our understanding of skin barrier function.

    Breastfeeding is universally accepted as the preferred feeding for all newborn infants, including premature infants. The World Health Organization, American Academy of Pediatrics, Canadian Pediatric Society and the European Society for Pediatric Gastroenterology, Hepatology and Nutrition, among others, recommend exclusive breastfeeding for the first 6 months in term infants, while complementary feeding is introduced over the next several months. However, for preterm infants, fortification is recommended to meet requirements. Human milk composition varies with the duration of lactation, within a day and even during one expression, and composition may be altered by method of storage and pasteurization. In this monograph, the use of human milk for premature infants, its limitations, strategies to overcome said limitations and follow-up studies will be reviewed. PMID:27347886

    Few studies have explored the importance of riboflavin deficiency in premature infants. Infants receiving human milk during the first 2 weeks become biochemically riboflavin-deficient, partly through photodegradation of riboflavin during the banking and delivery of human milk. Animal studies have shown that the metabolic lesions of riboflavin deficiency in sucking neonates differ in important ways from those seen later after weaning. Techniques are described for non-invasive study of functional riboflavin requirements by premature infants. It appears prudent to supplement human milk-fed babies with at least 300 micrograms riboflavin/day; but the potential danger of over supplementation in infants exposed to phototherapy is discussed.

    This study aimed to investigate the prohepcidin levels in premature newborns with oxygen radical diseases such as bronchopulmonary dysplasia, retinopathy of prematurity and necrotizing enterocolitis and to compare these levels with those of healthy premature newborns. Eighty premature infants (25-34 weeks gestational age) were enrolled. The patient group was composed of 38 premature babies with oxygen radical diseases, and the control group consisted of 42 healthy premature newborns. Complete blood count, serum iron and ferritin concentrations, iron-binding capacity (IBC), transferrin and prohepcidin levels were measured. The mean ferritin and prohepcidin levels were higher in the patient group than in the control group (p = 0.038 and p = 0.022, respectively). No significant correlations were found between serum prohepcidin levels and iron parameters. We believe that this finding will contribute to a greater understanding of the etiopathogenesis of oxygen radical diseases. There is a need for future studies to explore the link between underlying inflammatory mechanisms and hepcidin in oxygen radical diseases. PMID:25363011

    A solution of the well response to a prematurely terminated slug test (PTST) is presented. The advantages of a PTST over conventional slug tests are discussed. A systematized procedure of a PTST is proposed, where a slug test is terminated in the midpoint of the flow point, and the subsequent shut-in data is recorded and analyzed. This method requires a downhole shut-in device and a pressure transducer, which is no more than the conventional deep-well slug testing. As opposed to slug tests, which are ineffective when a skin is present, more accurate estimate of formation permeability can be made using a PTST. Premature termination also shortens the test duration considerably. Because in most cases no more information is gained by completing a slug test to the end, the author recommends that conventional slug tests be replaced by the premature termination technique. This study is part of an investigation of the feasibility of geologic isolation of nuclear wastes being carried out by the US Department of Energy and the National Cooperative for the Storage of Radioactive Waste of Switzerland.

    Bronchopulmonary dysplasia (BPD) is a chronic respiratory disease associated with premature birth that primarily affects infants born at less than 28 weeks’ gestational age. BPD is the most common serious complication experienced by premature infants, with more than 8,000 newly diagnosed infants annually in the United States alone. In light of the increasing numbers of preterm survivors with BPD, improving the current state of knowledge of long-term respiratory morbidity for infants with BPD is a priority. We undertook a comprehensive review of the published literature to analyze and consolidate current knowledge of the effects of BPD that are recognized at specific stages of life, including infancy, childhood, and adulthood. In this review, we discuss both the short-term and long-term respiratory outcomes of individuals diagnosed as infants with the disease and highlight the gaps in knowledge needed to improve early and lifelong management of these patients.

    The authors describe two premature infants who developed stage 3, zone I retinopathy of prematurity (ROP) with plus disease in both eyes, despite limited exposure to supra-ambient oxygen. Both infants received noninvasive respiratory support for several weeks. Both cases are notable because the ROP was more posterior and aggressive than is typical for the gestational ages or birth weights. These cases are insufficient to make definitive conclusions regarding the factors that cause ROP. Further investigation is required to determine if there is an association between the use of non-invasive respiratory support, even in the absence of supra-ambient oxygen, and severe ROP development.

    Background: The readiness of mothers to take care for infants at discharge is a critical issue. Poor readiness of mothers in taking care of premature infants at the time of discharge is associated with potential adverse consequences. This study examined the effect of implementing mothers’ empowerment program on the weight gain and duration of hospitalization in premature infants. Materials and Methods: This study was a quasi-experimental before-after study with a control group, in which 80 mothers with premature infants who were hospitalized in NICU Level II of two hospitals were recruited in the study. Mothers’ empowerment program was implemented as a three-stage training program for the intervention group. Mothers’ readiness questionnaire was completed by the mothers before the intervention and at the discharge time. The changes in mean of mothers’ readiness scores were compared in both the groups. Results: The mean of daily weight gain in infants of the intervention group (3.95 g) was significantly higher than that of the infants in the control group (−0.9 g) (P = 0.003). The average duration of hospitalization for infants in the intervention and control groups was 15.45 days and 20.95 days, respectively, showing a statistically significant difference (P = 0.003). Conclusions: Providing training to the mothers regarding how to care for premature infants can be a useful and effective method in the process of weight gain of premature and low-birth newborns, and may shorten the duration of infants’ hospitalization.

    Although oxidative stress and inflammation are important mechanisms in the pathophysiology of preeclampsia and preterm diseases, their contribution to the respiratory prognosis of premature infants of hypertensive mothers is not known. Our objective was to determine the levels of oxidative stress and inflammation markers in the airways of premature infants born to hypertensive and normotensive mothers, in the first 72 h of life, and to investigate whether they are predictors of bronchopulmonary dysplasia (BPD)/death. This was a prospective study with premature infants less than 34 weeks' gestation on respiratory support who were stratified into 2 groups: 32 premature infants of hypertensive mothers and 41 of normotensive women, with a mean gestational age of 29 weeks. Exclusion criteria were as follows: diabetes mellitus, chorioamnionitis, malformation, congenital infection, and death within 24 h after birth. The outcome of interest was BPD/death. Malondialdehyde (MDA), nitric oxide (NO), and interleukin 8 (IL-8) were measured in airway aspirates from the first and third days of life and did not differ between the groups. Univariate and multivariate statistical analyses were performed. The concentrations of MDA, NO, and IL-8 were not predictors of BPD/death. Premature infants who developed BPD/death had higher levels of IL-8 in the first days of life. The gestational age, mechanical ventilation, and a small size for gestational age were risk factors for BPD/death. In conclusion, the biomarkers evaluated were not increased in premature infants of hypertensive mothers and were not predictors of BPD/death. PMID:27533763

    Cholestasis in preterm infants has a multifactorial etiology. Risk factors include degree of prematurity, lack of enteral feeding, intestinal injury, prolonged use of parenteral nutrition (PN), and sepsis. Soy-based parenteral lipid emulsions have been implicated in the pathophysiology of PN-associated liver injury. Inflammation plays an important role. Medical therapies are used; however, their effects have not consistently proven effective. Evaluation of cholestasis involves laboratory work; direct bilirubin levels are used for diagnosis and trending. Adverse outcomes include risk for hepatobiliary dysfunction, irreversible liver failure, and death. Early enteral feedings as tolerated is the best way to prevent and manage cholestasis.

    OBJECTIVES: To estimate the direct costs of hospital stays for premature newborns in the Interlagos Hospital and Maternity Center in São Paulo, Brazil and to assess the difference between the amount reimbursed to the hospital by the Unified Health System and the real cost of care for each premature newborn. METHODS: A cost-estimate study in which hospital and professional costs were estimated for premature infants born at 22 to 36 weeks gestation during the calendar year of 2004 and surviving beyond one hour of age. Direct costs included hospital services, professional care, diagnoses and therapy, orthotics, prosthetics, special materials, and blood products. Costs were estimated using tables published by the Unified Health System and the Brasíndice as well as the list of medical procedures provided by the Brazilian Classification of Medical Procedures. RESULTS: The average direct cost of care for initial hospitalization of a premature newborn in 2004 was $2,386 USD. Total hospital expenses and professional services for all premature infants in this hospital were $227,000 and $69,500 USD, respectively. The costs for diagnostic testing and blood products for all premature infants totaled $22,440 and $1,833 USD. The daily average cost of a premature newborn weighing less than 1,000 g was $115 USD, and the daily average cost of a premature newborn weighing more than 2,500 g was $89 USD. Amounts reimbursed to the hospital by the Unified Health System corresponded to only 27.42% of the real cost of care. CONCLUSIONS: The cost of hospital stays for premature newborns was much greater than the amount reimbursed to the hospital by the Unified Health System. The highest costs corresponded to newborns with lower birth weight. Hospital costs progressively and discretely decreased as the newborns' weight increased. PMID:22012050

    Objectives: To assess the epidemiological characteristics of prematurity and survival rate in preterm infants diagnosed at a university hospital in the Eastern province of Saudi Arabia. Methods: A retrospective study was carried out of 476 preterm infants who were admitted with the diagnosis of prematurity to King Fahd Hospital of the University, Al-Khobar, Saudi Arabia, between June 2008 and 2013. Demographics, birth weight, and neonatal survival rate were analyzed. Results: Four hundred and seventy-six preterm infants were admitted with a total prevalence of 7.5%. Descriptive analysis revealed 55% were males. Extremely preterm infants (<28 weeks’ gestation) comprised 9% and very preterm infants (28 to <32 weeks’ gestation) comprised 20%. Extremely low-birth-weight (ELBW) infants (<1000 g) comprised 11%. One hundred and fifty-seven (32%) infants were small for gestational age. Out of the total number of ELBW infants, 58% of them were discharged. The overall mortality was 7.6%. The mortality rate of male infants was 53%. The survival to discharge according to gestational age ranged from 30-97.6%. Conclusion: The estimated prevalence of preterm births in a university hospital in eastern province of Saudi Arabia, is consistent with various studies from different parts of the world.

  5. Current concepts of oxygen management in retinopathy of prematurity.

    2014-01-01

    Retinopathy of prematurity (ROP) is a potentially blinding disorder in premature infants. The underlying pathophysiology is incompletely understood, limiting the prevention and treatment of this devastating condition. Current therapies are directed toward management of aberrant neovascularization thought to result from retinal ischemia in the developing preterm retina. The molecular mediators important for development of retinal ischemia and subsequent neovascular pathology are not fully understood. However, oxygen has been shown to be a key mediator of disease and the oxygen environment for preterm infants has been extensively studied. Despite this, the optimal oxygen environment for preterm infants remains unclear and recent works seeking to clarify this relationship demonstrate somewhat disparate findings. These data further substantiate that ROP is a complex disease with multifactorial etiology including genetic and environmental factors. Therefore, while environmental factors such as oxygen are important to our understanding of the disease process and care of preterm infants, identification of the molecular mediators downstream of oxygen which are necessary for development of ROP pathology will be critical to improve prevention, diagnosis and treatment strategies.

    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

    The birth of a premature infant creates anxiety and uncertainty for the parents, who may go through the same grieving process as parents who have lost a baby. Breastfeeding is considered a natural act, although it is not always an easy one for mother and premature infant to establish. Providing breast milk is one of the most important psychological benefits a mother can give her premature infant. Breast milk can be considered the ideal nutrition for preterm infants. Involving the parent in the child's care helps increase parental feelings of control. Neonatal nurses are in a unique position to help minimize parental stress by providing information. It is the responsibility of health professionals who care for premature infants to provide accurate information regarding the benefits and methods of breastfeeding, so that the mother can make an informed choice. The existence of a standardized care plan could assist in establishing breastfeeding in the pre-term newborn, to unify and guide practitioners in making decisions. The aim of this article is to describe the actions needed to be made by nursing staff to achieve successful breastfeeding. We present a standardized care plan that follows the NANDA (North American Nursing Diagnosis Association), NOC (Nursing Outcomes Classification), and NIC (Nursing Interventions Classification) and show how these needs could be managed by nursing professionals.

    2014-01-01

    Long chain polyunsaturated fatty acids (LCPUFA) including docosahexaenoic acid (DHA), are essential for normal vision and neurodevelopment. DHA accretion in utero occurs primarily in the last trimester of pregnancy to support rapid growth and brain development. Premature infants, born before this process is complete, are relatively deficient in this essential fatty acid. Very low birth weight (VLBW) infants remain deficient for a long period of time due to ineffective conversion from precursor fatty acids, lower fat stores, and a limited nutritional provision of DHA after birth. In addition to long- term visual and neurodevelopmental risks, VLBW infants have significant morbidity and mortality from diseases specific to premature birth, including bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC), and retinopathy of prematurity (ROP). There is increasing evidence that DHA has protective benefits against these disease states. The aim of this article is to identify the unique needs of premature infants, review the current recommendations for LCPUFA provision in infants, and discuss the caveats and innovative new ways to overcome the DHA deficiency through postnatal supplementation, with the long term goal of improving morbidity and mortality in this at risk population.

    While premature infants have a high need for positive interactions, both infants and their mothers are challenged by the infant's biological immaturity. This randomized clinical trial of 198 premature infants born at 29-34 weeks gestation and their mothers examined the impact of the H-HOPE (Hospital to Home: Optimizing the Infant's Environment) intervention on mother-premature infant interaction patterns at 6-weeks corrected age (CA). Mothers had at least 2 social environmental risk factors such as minority status or less than high school education. Mother-infant dyads were randomly assigned to the H-HOPE intervention group or an attention control group. H-HOPE is an integrated intervention that included (1) twice-daily infant stimulation using the ATVV (auditory, tactile, visual, and vestibular-rocking stimulation) and (2) four maternal participatory guidance sessions plus two telephone calls by a nurse-community advocate team. Mother-infant interaction was assessed at 6-weeks CA using the Nursing Child Assessment Satellite Training-Feeding Scale (NCAST, 76 items) and the Dyadic Mutuality Code (DMC, 6-item contingency scale during a 5-min play session). NCAST and DMC scores for the Control and H-HOPE groups were compared using t-tests, chi-square tests and multivariable analysis. Compared with the Control group (n = 76), the H-HOPE group (n = 66) had higher overall NCAST scores and higher maternal Social-Emotional Growth Fostering Subscale scores. The H-HOPE group also had significantly higher scores for the overall infant subscale and the Infant Clarity of Cues Subscale (p < 0.05). H-HOPE dyads were also more likely to have high responsiveness during play as measured by the DMC (67.6% versus 58.1% of controls). After adjustment for significant maternal and infant characteristics, H-HOPE dyads had marginally higher scores during feeding on overall mother-infant interaction (β = 2.03, p = 0.06) and significantly higher scores on the infant subscale (β = 0.75, p

    Intravitreal bevacizumab therapy in preterm infants for retinopathy of prematurity (ROP) can be associated with hypotension. We report twin preterm infants who developed hypotension within 1 day after intravitreal bevacizumab therapy for ROP. Before receiving the medication, their clinical statuses were stable and similar. The dose, procedure, and premedication were the same; however, twin B presented with hypotension for 3 days. Although bevacizumab-related hypotension has been described in product information (incidence rate 7%-15%), this is the first case report of intravitreal bevacizumab for ROP inducing hypotension. Physicians should be aware of intravitreal bevacizumab therapy-related hypotension when treating ROP. We suggest conducting a postmarketing active surveillance on the systemic adverse effects of this regimen in preterm infants. PMID:26743817

    Every year, an estimated 15 million infants are born prematurely (<37 weeks gestation) with premature birth rates ranging from 5 to 18% across 184 countries. Although there are a multitude of reasons for this high rate of preterm birth, once birth occurs, a major challenge of infant care includes the stabilization of respiration and oxygenation. Clinical care of this vulnerable infant population continues to improve, yet there are major areas that have yet to be resolved including the identification of optimal respiratory support modalities and oxygen saturation targets, and reduction of associated short- and long-term morbidities. As intermittent hypoxemia is a consequence of immature respiratory control and resultant apnea superimposed upon an immature lung, improvements in clinical care must include a thorough knowledge of premature lung development and pathophysiology that is unique to premature birth. In Part 1 of a two-part review, we summarize early lung development and diagnostic methods for cardiorespiratory monitoring. PMID:26583939

    2016-02-01

    This article reviews the evidence for an association between infant colic and migraine. Infant colic, or excessive crying in an otherwise healthy and well-fed infant, affects approximately 5%-19% of infants. Multiple case-control studies, a cross-sectional study, and a prospective cohort study have all found an association between infant colic and migraine. Although infant colic is often assumed to have a gastrointestinal cause, several treatment trials aimed at gastrointestinal etiologies have been negative. Teaching parents how to respond best to inconsolable crying may be helpful and important for preventing shaken baby syndrome. Given accumulating evidence for a connection between infant colic and pediatric migraine, future studies should examine migraine-oriented treatments for infant colic. Infant colic should be moved into the main body of International Classification of Headache Disorders (ICHD-III beta) as one of the "Episodic syndromes that may be associated with migraine."

    Asthma is the most common chronic disease of childhood, affecting millions of children in the United States and worldwide. Prematurity is a risk factor for asthma, and certain ethnic or racial minorities such as Puerto Ricans and non-Hispanic blacks are disproportionately affected by both prematurity and asthma. In this review, we examine current evidence to support maternal psychosocial stress as a putative link between prematurity and asthma, while also focusing on disruption of the hypothalamic-pituitary-adrenal (HPA) axis and immune responses as potential underlying mechanisms for stress-induced "premature asthma." Prenatal stress may cause not only abnormalities in the HPA axis but also epigenetic changes in the fetal glucocorticoid receptor gene (NR3C1), leading to impaired glucocorticoid metabolism. Moreover, maternal stress can alter fetal cytokine balance, favoring TH2 (allergic) immune responses characteristic of atopic asthma: interleukin 6 (IL-6), which has been associated with premature labor, can promote TH2 responses by stimulating production of IL-4 and IL-13. Given a link among stress, prematurity, and asthma, future research should include birth cohorts aimed at confirming and better characterizing "premature asthma." If confirmed, clinical trials of prenatal maternal stress reduction would be warranted to reduce the burden of these common comorbidities. While awaiting the results of such studies, sound policies to prevent domestic and community violence (eg, from firearms) are justified, not only by public safety but also by growing evidence of detrimental effects of violence-induced stress on psychiatric and somatic health.

    The data presented in this review of the history of premature care in the United States is limited to published material available within the local area. Additional manuscripts, records, and oral histories, would provide a more comprehensive perspective. The period from 1900 to the early 1940s represents the beginning of premature care in the United States characterized by efforts to provide an intrauterinelike environment. Energies were focused on the three identified basic needs of temperature support, nutrition, and protection against infection. The idea of caring for prematures in an especially designated area in the hospital evolved, and premature stations or wards were created. Advances in technology resulted in sophisticated systems for providing warmth for infants and some interventions for respiratory support using oxygen and an infant ventilator. The dangers of cold stress during transport were addressed with attempts to provide warmth using an especially designed transport incubator. A revolutionary growth in technology combined with the nationwide coordinated effort for organizing regional care has characterized this past 30-year period of premature care (1950-1980). The infant is now surrounded by sophisticated life-support systems and receives medical care from a much broader knowledge base than was available in the past. The environment for premature care has truly surpassed any expectations that health care professionals of the past may have held when the concept of an incubator emerged. Nursing of premature infants has expanded with the level of sophisticated equipment and the knowledge of the premature infant's physiologic needs. Nurses are no longer the gatekeepers of a sanctuary against infection. They care for the premature and the family by providing support, information, and caring during an emotionally stressful time. As the premature's physiological condition stabilizes, the nurse helps the family learn to care for the infant and thus

Topical anesthetic creams and daily or on-demand selective serotonin reuptake inhibitor (SSRI) treatment forms the basis of pharmacotherapy for premature ejaculation today, in spite of low adherence by patients. Psychotherapy may improve the outcomes when combined with these treatment modalities. Tramadol and phosphodiesterase type 5 inhibitors have a limited role in the management of premature ejaculation.

    Premature ejaculation (PE) is the most common form of male sexual dysfunction, with an estimated worldwide prevalence of 20–30%.1 Although PE is not life threatening, it has significant impact on quality of life. The fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR)defines PE as “persistent or recurrent ejaculation with minimal sexual stimulation before, on, or shortly after penetration and before the person wishes it” that “causes marked distress or interpersonal difficulty” and “is not due exclusively to the direct effects of a substance.”2 The International Society for Sexual Medicine, which recently modified the definition to include the threshold ejaculatory latency time, defines PEas “male sexual dysfunction characterized by ejaculation which always or nearly always occurs prior to or within 1 min of vaginal penetration; the inability to delay ejaculation on all or nearly all vaginal penetrations; and negative personal consequences such as distress, bother, frustration, and/or the avoidance of sexual intimacy.”3 The lack of ejaculatory control is consistent among all clinical definitions of PE and is a highly sensitive predictor of the condition.

    The requirements of growth and organ development create a challenge in nutritional management of newborn infants, especially premature newborn and intestinal-failure infants. Since their feeding may increase the risk of necrotizing enterocolitis, some high-risk infants receive a small volume of feeding or parenteral nutrition (PN) without enteral feeding. This review summarizes the current research progress in the nutritional management of newborn infants. Searches of MEDLINE (1998-2007), Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 3, 2007), abstracts and conference proceedings, references from relevant publications in the English language were performed, showing that breast milk is the preferred source of nutrients for enteral feeding of newborn infants. The number of nutrients found in human milk was recommended as a guideline in establishing the minimum and maximum levels in infant formulas. The fear of necrotizing enterocolitis and feeding intolerance are the major factors limiting the use of the enteral route as the primary means of nourishing premature infants. PN may help to meet many of the nutritional needs of these infants, but has significant detrimental side effects. Trophic feedings (small volume of feeding given at the same rate for at least 5 d) during PN are a strategy to enhance the feeding tolerance and decrease the side effects of PN and the time to achieve full feeding. Human milk is a key component of any strategy for enteral nutrition of all infants. However, the amounts of calcium, phosphorus, zinc and other nutrients are inadequate to meet the needs of the very low birth weight (VLBW) infants during growth. Therefore, safe and effective means to fortify human milk are essential to the care of VLBW infants. PMID:18985802

    While premature infants have a high need for positive interactions, both infants and their mothers are challenged by the infant‘s biological immaturity. This randomized clinical trial of 198 premature infants born at 29–34 weeks gestation and their mothers examined the impact of the H-HOPE (Hospital to Home: Optimizing the Infant’s Environment) intervention on mother-premature infant interaction patterns at 6-weeks corrected age (CA). Mothers had at least 2 social environmental risk factors such as minority status or less than high school education. Mother-infant dyads were randomly assigned to the H-HOPE intervention group or an attention Control group. H-HOPE is an integrated intervention that included (1) twice-daily infant stimulation using the ATVV (auditory, tactile, visual, and vestibular-rocking stimulation) and (2) four maternal participatory guidance sessions plus two telephone calls by a nurse-community advocate team. Mother-infant interaction was assessed at 6-weeks CA using the Nursing Child Assessment Satellite Training–Feeding Scale (NCAST, 76 items) and the Dyadic Mutuality Code (DMC, 6-item contingency scale during a 5-minute play session). NCAST and DMC scores for the Control and H-HOPE groups were compared using t-tests, chi-square tests and multivariable analysis. Compared with the Control group (n = 76), the H-HOPE group (n = 66) had higher overall NCAST scores and higher maternal Social-Emotional Growth Fostering Subscale scores. The H-HOPE group also had significantly higher scores for the overall infant subscale and the Infant Clarity of Cues Subscale (p < 0.05). H-HOPE dyads were also more likely to have high responsiveness during play as measured by the DMC (67.6% versus 58.1% of controls). After adjustment for significant maternal and infant characteristics, H-HOPE dyads had marginally higher scores during feeding on overall mother-infant interaction (β = 2.03, p = .06) and significantly higher scores on the infant subscale (

    Premature ovarian failure (POF) is clinically suspected by amenorrhea and confirmed by an elevated FSH serum level above 40 mUI/L (even 20 mUI/L) twice, in a woman before the age of 40. Prevalence of POF is between 1 to 2% in women. In 90% of cases, no aetiology is identified. Obvious causes are chemotherapy, pelvic radiotherapy, ovarian surgery and diethylstilbestrol exposure in utero. A karyotype should be performed as Turner Syndrome is the most frequent genetic cause of POF. Some X abnormalities such as X deletion or X autosome translocation can be found. FMR1 pre-mutation (fragile X syndrome) should be searched for, even though no cases of mental retardation are known, in the family. Other genetic abnormalities can be suggested by associated symptoms (i.e.: FOXL2, SF1 mutations). Auto-immune aetiology can be suspected if other auto-immune features are present, however, there are no reliable auto-antibodies to confirm auto-immunity in POF. Treatment of POF is based on hormonal replacement therapy in order to avoid estrogen deficiency, suppress vasomotor symptoms and avoid bone loss as well as cardiovascular risk. Estrogens should be associated with progesterone or a progestin, at least up to the age of 51. Patients with POF should be informed that spontaneous pregnancies may occur (in 5% of cases). In case of desire of pregnancy, the patient should be oriented to a specialized unit for in vitro fertilization with oocyte donation. Psychological support is essential and should be part of the treatment. POF is associated with an increased risk of emotional distress and depression. No preventive treatment of POF is available so far. PMID:24157186

    Brain development is a complex process of micro- and macrostructural events that include neuronal and glial proliferation and migration, myelination, and organizational development of cortical layers and circuitry. Recent progress in understanding these processes has provided insight into the pathophysiology of brain injury and alterations of cerebral development in preterm infants. A key factor of abnormalities in the preterm infant is the maturational stage of the brain at the time of birth. This review summarizes current data on normal brain development, patterns of brain injury in the preterm infant, and the associated axonal/neuronal disturbances that occur in the setting of this injury, often termed encephalopathy of prematurity.

    Visuospatial functions are very important in learning process and development of abstract thought during childhood. Several studies show that preterm and low birth weight infants obtain lower scores in test that assess cognitive functions, specially in the first year of life. These differences are attenuated over time, but a developmental delay that affects working memory and visuospatial process still persists. It is unclear what factors are involved in development of these functions, and pre- or perinatal factors may interfere with the proper conduct of the same, but have been described anatomical and physiological differences between the preterm and term brain that could explain somewhere in these alterations. The different selective vulnerability to hypoxia between immature brain in which preoligodendrocytes and subplate neurons predominate, and mature brain, determine differences in the pattern of injury from hypoxia with greater involvement of the periventricular white matter in preterm children. This lesional pattern leaves to a dysfunction in attentional and visuospatial process, due to the increased vulnerability of the regions involved in the dorsal pathway of visual processing.

  18. Preclinical Models of Encephalopathy of Prematurity

    2015-01-01

    Encephalopathy of prematurity (EoP) encompasses the central nervous system (CNS) abnormalities associated with injury from preterm birth. Although rapid progress is being made, limited understanding exists of how the cellular and molecular CNS injury from early birth manifests as the myriad of neurological deficits in children who are born preterm. More importantly, this lack of direct insight into the pathogenesis of these deficits hinders both our ability to diagnose those infants who are at risk in real-time and could potentially benefit from treatment, and our ability to develop more effective interventions. Current barriers to clarifying the pathophysiology, developmental trajectory, injury timing and evolution include preclinical animal models that only partially recapitulate the molecular, cellular, histological and functional abnormalities observed in the mature CNS following EoP. Inflammation from hypoxic-ischemic and/or infectious injury induced in utero in lower mammals, or actual prenatal delivery of more phylogenetically-advanced mammals, are likely to be the most clinically relevant EOP models, facilitating translation to benefit infants. Injury timing, type, severity and pathophysiology need to be optimized to address the specific hypothesis being tested. Functional assays of the mature animal following perinatal injury to mimic EoP should ideally test for the array of neurological deficits commonly observed in preterm infants including gait, seizure threshold, cognitive and behavioral abnormalities. Here, we review the merits of various preclinical models, identify gaps in knowledge that warrant further study and consider challenges that animal researchers may face in embarking on these studies. While no one model system is perfect, insights relevant to the clinical problem can be gained with interpretation of experimental results within the context of inherent limitations of the chosen model system. Collectively, optimal use of multiple models will

    2016-01-01

    AIM To detect the incidence of retinopathy of prematurity (ROP) in a tertiary referral neonatal intensive care unit in upper Egypt and to describe the obstacles faced during implementing the screening protocol for the first time. METHODS Consecutive infants were enrolled at birth and screened for ROP. We used the UK ROP guideline (May 2008) for infant selection, follow up and treatment. Repeat examinations were performed until retinal vascularisation was complete. RESULTS Fifty-two infants were enrolled: 24 males and 28 females. Mean gestational age was 31.3wk (±2.8 SD) and mean birth weight was 1234.6 g (±221.1 SD). Incidence of ROP was 36.5% (stages 1, 2, 3 and 4a were 9.6%, 9.6%, 15.4% and 1.9% respectively), no stages 4b or 5 were found in this series. Six infants (11.5%) died during screening without ROP, 25 infants (48.1%) were discharged from screening with retinal vascularisation reaching zone III, 5 infants (9.6%) were treated with indirect diode with or without additional cryotherapy and 16 infants (30.8%) were lost to follow up. In this series gestational age rather than birth weight was found significantly correlated and predictive (P<0.05) with ROP stages. CONCLUSION ROP in a single site in Upper Egypt appears to have comparable incidence to other areas worldwide. The main screening obstacle was missing cases due to the absence of a national ROP screening protocol. PMID:26949647

    2008-01-01

    BACKGROUND Retinal imaging with remote interpretation could decrease the number of diagnostic eye examinations that premature infants need for the detection of retinopathy of prematurity and thus decrease the time demand on the relatively small pool of ophthalmologists who perform retinopathy of prematurity examinations. OBJECTIVE Our goal was to review systematically the evidence regarding the reliability, validity, safety, costs, and benefits of retinal imaging to screen infants who are at risk for retinopathy of prematurity. METHODS We searched Medline, the Cochrane library, CINAHL, and the bibliographies of all relevant articles. All English-language studies regardless of design with primary data about our study questions were included. We excluded (1) studies that only included subjects with retinopathy of prematurity, (2) hypothetical models other than cost-effectiveness studies, and (3) validity studies without sufficient data to determine prevalence, sensitivity, and specificity or that only evaluated subjects for 1 component of retinopathy of prematurity (eg, plus disease only). RESULTS Studies of only 1 retinal imaging device (RetCam [Clarity Medical Systems, Inc, Pleasanton, CA]) met the inclusion criteria. There was a wide range in reported sensitivity, but specificity was high. There were several important limitations noted, including the eye as the unit of analysis instead of the individual or variations in the criteria for determining a true-positive or true-negative screening result. The risk of retinal hemorrhage resulting from imaging is low, and systemic effects (eg, bradycardia, hypertension, decreased oxygen saturation) are mild. No generalizable cost-effectiveness data were found. CONCLUSIONS The evidence base is not sufficient to recommend that retinal imaging be routinely adopted by NICUs to identify infants who have serious retinopathy of prematurity. PMID:18829807

    Level of prematurity is an objective criterion for determining the health welfare of the population. Several family background factors of the mother increases the risk of preterm birth child - family status, unwanted pregnancy, etc. Pregnancy among unmarried women and unwanted pregnancy are associated with a higher risk of giving premature baby. Aim of this study is a survey and analysis of factors of family background of the mother (family status and unplanned pregnancy) and their influence on the birth of a premature baby. The survey found nearly three times higher risk OR = 2,83 95 % CI (1,7-4,7) for the birth of a premature baby among unmarried mothers compared to married women, and twice as high proportion of unplanned pregnancy mothers of preterm infants - 20.7% compared to terminfants-10.4%.

    The middle range nursing theory of chronic sorrow offers guidance in the care of families dealing with an ongoing disparity. One such example is the reality of having an infant born prematurely with serious medical conditions. Nurses working in a neonatal intensive care unit, and other pediatric settings need to assess families for symptoms of fear, helplessness or sadness and signs of chronic sorrow. A case scenario provides an example of chronic sorrow. Nurses need to assist families in developing healthy coping strategies so as to alleviate any effects of chronic sorrow that they may experience. PMID:24269307

    Controversy surrounding the decision to resuscitate at the limits or borderline of viability has been at the center of neonatal ethical debate for decades. This debate has led to numerous reports from individual institutions, councils, and advisory committees that all have remarkable consistency in the development of gestational age-based guidelines. This article reviews legal or regulatory concerns that may contradict ethical discussion and guidelines, discriminatory and scientific basis concerns with consensus guidelines, and personal controversy about how to determine best interest. Guidelines are a reasonable place to start in helping determine parental authority and autonomy. The article also addresses controversies raised in counseling and costs. PMID:25459775

    AIM—To assess whether treatment of premature infants with dopamine is a risk factor for development of retinopathy of prematurity (ROP).
METHODS—A retrospective case series analysis of two groups was utilised with a minimum follow up of 6 months. Clinical profiles and patient risk factors were identified along with an evaluation of ROP progression and an analysis of clinical outcome. All infants were seen in a single community neonatal intensive care unit (NICU). 41 consecutive high risk infants were identified during a 36 month period whose birth weight was less than 1000 grams and who remained in the NICU without transfer until at least 28 days of age. Dilated indirect ophthalmoscopy fundus examinations were performed on all infants to identify the degree of and progression to threshold ROP.
RESULTS—18 of 41 infants were treated with dopamine for hypotension. The group of infants requiring dopamine differed statistically from the non-dopamine treated group by having a slightly higher birth weight, a greater incidence of hypotension and colloid treatment, and in manifesting more advanced respiratory disease. Within the dopamine treated group, 12 of 18 infants (67%) reached prethreshold ROP and seven infants (39%) reached threshold ROP requiring laser treatment. In contrast, only three of the infants (13%) who did not require dopamine for hypotension progressed to prethreshold (p=0.001) and only one of these infants (4%) progressed to threshold ROP (p = 0.02). Logistic regression analysis among other variables demonstrated that dopamine use and gestational age are important factors in this low birthweight population for predicting the development of threshold ROP (dopamine use: adjusted odds ratio = 119.88, p = 0.0061; gestational age: adjusted odds ratio = 0.061, p = 0.0043).
CONCLUSIONS—Dopamine use in low birthweight infants may therefore be a risk factor for the development of threshold ROP. More vigilant screening of high risk

    OBJECTIVE: We sought to determine if a center’s approach to care of premature infants at the youngest gestational ages (22–24 weeks’ gestation) is associated with clinical outcomes among infants of older gestational ages (25–27 weeks’ gestation). METHODS: Inborn infants of 401 to 1000 g birth weight and 22 0/7 to 27 6/7 weeks’ gestation at birth from 2002 to 2008 were enrolled into a prospectively collected database at 20 centers participating in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. Markers of an aggressive approach to care for 22- to 24-week infants included use of antenatal corticosteroids, cesarean delivery, and resuscitation. The primary outcome was death before postnatal day 120 for infants of 25 to 27 weeks’ gestation. Secondary outcomes were the combined outcomes of death or a number of morbidities associated with prematurity. RESULTS: Our study included 3631 infants 22 to 24 weeks’ gestation and 5227 infants 25 to 27 weeks’ gestation. Among the 22- to 24-week infants, use of antenatal corticosteroids ranged from 28% to 100%, cesarean delivery from 13% to 65%, and resuscitation from 30% to 100% by center. Centers with higher rates of antenatal corticosteroid use in 22- to 24-week infants had reduced rates of death, death or retinopathy of prematurity, death or late-onset sepsis, death or necrotizing enterocolitis, and death or neurodevelopmental impairment in 25- to 27-week infants. CONCLUSIONS: This study suggests that physicians’ willingness to provide care to extremely low gestation infants as measured by frequency of use of antenatal corticosteroids is associated with improved outcomes for more-mature infants.

Presence of an experienced team during the delivery of extremely preterm infant to improve outcome is reviewed. Adaptation from foetal to neonatal cardiorespiratory haemodynamics is dependent on establishing an optimal functional residual capacity in the extremely preterm infants, thus enabling adequate gas exchange. There is sufficient evidence for a gentle approach to stabilisation of these fragile infants in the delivery room.

    Blindness from retinopathy of prematurity (ROP) in Australian and New Zealand is an uncommon event although 3% of <31 weeks gestation infants receive treatment for the disease. New world-wide estimates of the incidence of blindness from ROP are much higher than previously at 20 000 children annually. The impact of severe ROP can be reduced through good evidence-based care of very preterm infants and careful organisation of eye examinations and follow-up services. Recent oxygen saturation targeting trial results might mean the adoption of higher targets than formerly in very preterm infants and will require vigilance to ensure all eligible infants are examined appropriately. A true screening examination for acute ROP might involve non-opthalmologists obtaining photographic retinal images and remote reading of these. Although treatment with laser gives good outcomes, there is interest in intravitreal anti-vascular endothelial factor agents, but issues concerning the systemic safety and retinal results of such treatment are unresolved.

    Retinopathy of prematurity (ROP) is a vasoproliferative disorder affecting low birth weight infants. Although timely diagnosis and treatment can significantly reduce the risk of severe complications, ROP remains a leading cause of childhood blindness worldwide. Limitations of current disease management strategies include extensive travel and logistical coordination requirements for ophthalmologists and neonatologists, decreasing availability of adequately-trained ophthalmologists at the point of care, variability in how retinal findings are diagnosed and documented, and a growing need for ROP care worldwide. Store-and-forward telemedicine is an emerging technology by which medical data are captured for subsequent interpretation by a remote expert. This has potential to improve accessibility, quality, and cost of ROP management. In this paper, we summarize the current evaluation data on applications of telemedicine for ROP, particularly involving the diagnostic accuracy and reliability of remote image interpretation by experts. We also address challenges such as the cost-effectiveness of telemedicine, and highlight potential barriers to implementation of these systems. Understanding these principles is essential to determine future directions in research and development of telemedicine systems for ROP, as well as for other ophthalmic diseases. PMID:19665742

    Although survival has improved significantly in recent years, prematurity remains a major cause of infant and childhood mortality and morbidity. Preterm births (<37 weeks of gestation) account for 8% of live births representing >50,000 live births each year in the UK. Preterm birth, irrespective of whether babies require neonatal intensive care, is associated with increased respiratory symptoms, partially reversible airflow obstruction and abnormal thoracic imaging in childhood and in young adulthood compared with those born at term. Having failed to reach their optimal peak lung function in early adulthood, there are as yet unsubstantiated concerns of accelerated lung function decline especially if exposed to noxious substances leading to chronic respiratory illness; even if the rate of decline in lung function is normal, the threshold for respiratory symptoms will be crossed early. Few adult respiratory physicians enquire about the neonatal period in their clinical practice. The management of these subjects in adulthood is largely evidence free. They are often labelled as asthmatic although the underlying mechanisms are likely to be very different. Smoking cessation, maintaining physical fitness, annual influenza immunisation and a general healthy lifestyle should be endorsed irrespective of any symptoms. There are a number of clinical and research priorities to maximise the quality of life and lung health in the longer term not least understanding the underlying mechanisms and optimising treatment, rather than extrapolating from other airway diseases.

    Retinopathy of prematurity (ROP) is a vasoproliferative disorder of the retina occurring principally in new born preterm infants. It is an avoidable cause of childhood blindness. With the increase in the survival of preterm babies, ROP has become the leading cause of preventable childhood blindness throughout the world. A simple screening test done within a few weeks after birth by an ophthalmologist can avoid this preventable blindness. Although screening guidelines and protocols are strictly followed in the developed nations, it lacks in developing economies like India and China, which have the highest number of preterm deliveries in the world. The burden of this blindness in these countries is set to increase tremendously in the future, if corrective steps are not taken immediately. ROP first emerged in 1940s and 1950s, when it was called retrolental fibroplasia. Several epidemics of this disease were and are still occurring in different regions of the world and since then a lot of research has been done on this disease. However, till date very few comprehensive review articles covering all the aspects of ROP are published. This review highlights the past, present and future strategies in managing this disease. It would help the pediatricians to update their current knowledge on ROP. PMID:26862500

    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. PMID:24676200

    Exposure to topically applied substances occurs routinely in premature and hospitalized infant care. Safety determinations are most accurate when exposures are based on appropriately designed studies to capture variations in practice patterns and population heterogeneity. Current safety assessments may not reflect actual practice resulting in overly conservative or understated default assumptions for toxicological determinations. We quantified the amount of baby wipes lotion transferred to premature and term neonatal skin as grams/kg body weight/day. We observed the soil type and number of wipes used for skin cleansing and measured lotion transfer from one wipe applied to freshly clean, dry skin. A Bayesian imputation approach was applied to compute lotion exposure and produce summary statistics. Model covariates were age and weight at evaluation, gender, soil type, soil amount, and number of diaper changes per day. Lotion transfer was measured for 66 premature and 55 term neonates with 449 and 254 evaluations, respectively. The wipes per day was 12.52 overall (all infants and soils), 12.78 for premature and 12.21 for term neonates. Lotion transfer was 0.20 g/kg/day (95th percentile) overall, 0.21 for premature and 0.19 for term neonates. The statistical and experimental methodology represents an effective strategy for determining exposure and assessing risk. PMID:26285167

  4. Neuromodulation of Limb Proprioceptive Afferents Decreases Apnea of Prematurity and Accompanying Intermittent Hypoxia and Bradycardia

    2016-01-01

    Background Apnea of Prematurity (AOP) is common, affecting the majority of infants born at <34 weeks gestational age. Apnea and periodic breathing are accompanied by intermittent hypoxia (IH). Animal and human studies demonstrate that IH exposure contributes to multiple pathologies, including retinopathy of prematurity (ROP), injury to sympathetic ganglia regulating cardiovascular action, impaired pancreatic islet cell and bone development, cerebellar injury, and neurodevelopmental disabilities. Current standard of care for AOP/IH includes prone positioning, positive pressure ventilation, and methylxanthine therapy; these interventions are inadequate, and not optimal for early development. Objective The objective is to support breathing in premature infants by using a simple, non-invasive vibratory device placed over limb proprioceptor fibers, an intervention using the principle that limb movements trigger reflexive facilitation of breathing. Methods Premature infants (23–34 wks gestational age), with clinical evidence of AOP/IH episodes were enrolled 1 week after birth. Caffeine treatment was not a reason for exclusion. Small vibration devices were placed on one hand and one foot and activated in 6 hour ON/OFF sequences for a total of 24 hours. Heart rate, respiratory rate, oxygen saturation (SpO2), and breathing pauses were continuously collected. Results Fewer respiratory pauses occurred during vibration periods, relative to baseline (p<0.005). Significantly fewer SpO2 declines occurred with vibration (p<0.05), relative to control periods. Significantly fewer bradycardic events occurred during vibration periods, relative to no vibration periods (p<0.05). Conclusions In premature neonates, limb proprioceptive stimulation, simulating limb movement, reduces breathing pauses and IH episodes, and lowers the number of bradycardic events that accompany aberrant breathing episodes. This low-cost neuromodulatory procedure has the potential to provide a non

    Retinopathy of prematurity (ROP) affects only premature infants, but as premature births increase in many areas of the world, ROP has become a leading cause of childhood blindness. Blindness can occur from aberrant developmental angiogenesis that leads to fibrovascular retinal detachment. To treat severe ROP, it is important to study normal developmental angiogenesis and the stresses that activate pathologic signaling events and aberrant angiogenesis in ROP. Vascular endothelial growth factor (VEGF) signaling is important in both physiologic and pathologic developmental angiogenesis. Based on studies in animal models of oxygen-induced retinopathy (OIR), exogenous factors such as oxygen levels, oxidative stress, inflammation, and nutritional capacity have been linked to severe ROP through dysregulated signaling pathways involving hypoxia-inducible factors and angiogenic factors like VEGF, oxidative species, and neuroprotective growth factors to cause phases of ROP. This translational science review focuses on studies performed in animal models of OIR representative of human ROP and highlights several areas: mechanisms for aberrant growth of blood vessels into the vitreous rather than into the retina through over-activation of VEGF receptor 2 signaling, the importance of targeting different cells in the retina to inhibit aberrant angiogenesis and promote physiologic retinal vascular development, toxicity from broad and targeted inhibition of VEGF bioactivity, and the role of VEGF in neuroprotection in retinal development. Several future translational treatments are discussed, including considerations for targeted inhibition of VEGF signaling instead of broad intravitreal anti-VEGF treatment. PMID:25444347

    Most enterovirus infection in the neonate and young infant is asymptomatic, but serious disease may occur, especially if acquired perinatally. We report the first case, to our knowledge, of asymptomatic enterovirus aseptic meningitis, and of concurrent enterovirus aseptic meningitis in premature triplets. Ten-week-old, 31-week-estimated gestational age premature triplet boys were diagnosed with enterovirus aseptic meningitis on the same day. Two of the triplets developed symptoms on the day of admission, while the third remained symptom free throughout the infection. All three recovered completely and are healthy more than a decade later. PMID:23946897

    Latent class analyses can be used early in the postpartum period to identify mothers of preterm infants experiencing similar patterns of psychological distress symptoms, but whether these classes of mothers also differ in parental responses to their infants or in their infants' development is largely unknown. In this longitudinal multisite-repeated measures study, we evaluated the usefulness of three psychological distress classes (low distress, high depressive and anxiety symptoms, and extreme distress) in predicting mother-infant interactions, quality of home environment, and infant development in 229 mother-preterm infant pairs. Mothers completed psychological distress questionnaires at study entry; parent-infant interaction was recorded at 2 and 6 months of age corrected for prematurity; and infant developmental data were collected 12 months corrected age. Mothers in the extreme distress class engaged in more developmental stimulation at 2 months (β = .99, p < 0.01) and at 6 months (β = 1.38, p < .01) than mothers in the other classes and had better quality of home environment at 2 months (β = 2.52, p = .03). When not controlling for neurological insult, infants of mothers in the extreme distress class had poorer cognitive (β = -10.28, p = .01) and motor (β = -15.12, p < .01) development scores at 12 months corrected age than infants of mothers in the other distress classes, but after controlling for infant neurological insult, there were no differences in cognitive, motor, and language development based on maternal psychological distress class. © 2016 Wiley Periodicals, Inc.

  8. Caffeine for apnea of prematurity: a neonatal success story.

    PubMed

    2014-01-01

    Caffeine, a methylxanthine and nonspecific inhibitor of adenosine receptors, is an example of a drug that has been in use for more than 40 years. It is one of the most commonly prescribed drugs in neonatal medicine. However, until 2006, it had only a few relatively small and short-term studies supporting its use. It is thanks to the efforts of Barbara Schmidt and the Caffeine for Apnea of Prematurity (CAP) Trial Group that we now have high-quality and reliable data not only on short-term but also long-term outcomes of caffeine use for apnea of prematurity. CAP was an international, multicenter, placebo-controlled randomized trial designed to determine whether survival without neurodevelopmental disability at a corrected age of 18 months is improved if apnea of prematurity is managed without methylxanthines in infants at a high risk of apneic attacks. CAP was kept simple and pragmatic in order to allow for maximum generalizability and applicability. Infants with birth weights of 500-1,250 g were enrolled during the first 10 days of life if their clinicians considered them to be candidates for methylxanthine therapy. The most frequent indication for therapy reported in CAP was treatment of documented apnea, followed by the facilitation of the removal of an endotracheal tube. Only about 20% of the neonatologists in the trial started caffeine for the prevention of apnea and the findings of CAP cannot automatically be extrapolated to an exclusive prophylactic indication. However, recent data suggest that the administration of prophylactic methylxanthine by neonatologists is now common practice. PMID:24931325

    Objective To explore (1) whether extremely low gestational age newborns exposed to inflammation-associated pregnancy disorders differ in retinopathy of prematurity (ROP) risk from infants exposed to placenta dysfunction-associated disorders, and (2) whether ROP risk associated with postnatal hyperoxemia and bacteremia differs among infants exposed to these disorders. Methods Pregnancy disorders resulting in preterm birth include inflammation-associated: preterm labor, prelabor premature rupture of membranes (pPROM), cervical insufficiency, and abruption and placenta dysfunction-associated: preeclampsia and fetal indication. The risk of severe ROP associated with pregnancy disorders was evaluated by multivariable analyses in strata defined by potential effect modifiers, postnatal hyperoxemia and bacteremia. Results Compared to preterm labor, infants delivered after pPROM were at reduced risk of plus disease (Odds ratio = 0.4, 95% confidence interval: 0.2–0.8) and prethreshold/threshold ROP (0.5, 0.3–0.8). Infants delivered after abruption had reduced risk of zone I ROP (0.2, 0.1–0.8) and prethreshold/threshold ROP (0.3, 0.1–0.7). In stratified analyses, infants born after placenta dysfunction had higher risks of severe ROP associated with subsequent postnatal hyperoxemia and bacteremia than infants born after inflammation-associated pregnancy disorders. Conclusion Infants exposed to placenta dysfunction have an increased risk of severe ROP following postnatal hyperoxemia and bacteremia compared to infants exposed to inflammation-associated pregnancy disorders.

    Infant skin is critical to the newborn child's transition from the womb environment to the journey to self-sufficiency. This review provides an integrative perspective on the skin development in full term and premature infants. There is a particular focus on the role of vernix caseosa and on the implications of skin development for epidermal penetration of exogenous compounds. Healthy full-term newborn skin is well-developed and functional at birth, with a thick epidermis and well-formed stratum corneum (SC) layers. Transepidermal water loss is very low at birth, equal to, or lower than adults, indicating a highly effective skin barrier. Vernix facilitates SC development in full-term infants through a variety of mechanisms including physical protection from amniotic fluid and enzymes, antimicrobial effects, skin surface pH lowering, provision of lipids, and hydration. Premature infants, particularly those of very low birth weight, have a poor skin barrier with few cornified layers and deficient dermal proteins. They are at increased risk for skin damage, increased permeability to exogenous agents and infection. The SC barrier develops rapidly after birth but complete maturation requires weeks to months. The best methods for caring for infant skin, particularly in the diaper region, are described and related to these developmental changes. PMID:25889127

    To date, we have no uniform definition of ejaculatio praecox. In a qualitative approach, premature ejaculation is ascribed to a failure to control excitement. As causes, organic disorders and erectile dysfunction must be excluded. The majority of cases, however, are due to psychological or partnership problems. The history-taking should aim, in particular, to uncover possible anxiety in conjunction with premature orgasm, and also to establish the reactions of the partner. As therapy, medication (local anesthetics, antidepressive agents, PDE-5 inhibitors) and sexual-therapeutic measures are available. Since few sufferers take the initiative in seeking treatment, particular importance attaches to providing the public with information about the therapeutic options for treating this common disorder.

    Premature neonates represent a fragile patient population, often subjected to intensive clinical care and multiple drug therapy, which must be monitored carefully and continuously. The difficult and painful nature of repetitive blood sampling, particularly in this population, has provided considerable impetus for the development of noninvasive methods for monitoring blood analytes. Reverse iontophoresis, a relatively new technology already used for the transdermal monitoring of blood glucose levels in adults, may be particularly well-suited to exploit the unique properties of preterm neonatal skin. The underdevelopment of the premature infant's epidermis, and more specifically the stratum corneum (SC), results in an increased permeability to molecular transport. In this study, we have investigated the feasibility of reverse iontophoretic monitoring of two model drugs, caffeine and theophylline, which are often administered to premature neonates. To this purpose, tape-stripped porcine skin in vitro, which has been previously demonstrated to be an excellent model for premature neonatal skin, was employed. Reverse iontophoresis across intact membranes enabled a quantifiable extraction of both drugs predominantly at the cathode compartment. The mechanism of extraction of these essentially neutral drugs (caffeine and theophylline being uncharged at pH 7.4) was electroosmosis. However, when the SC was removed by progressive tape-stripping, the amounts of drugs extracted by reverse iontophoresis were equivalent to those obtained by passive diffusion. In these circumstances, therefore, the benefit and usefulness of the applied electric field had been lost. In summary, the absence of an at least partially functional skin barrier obviates, in the case of neutral molecules, the control (and directional transport) offered by iontophoresis; in contrast, for ionized species, where the principal iontophoretic transport mechanism is electromigration, the approach should be valid

    Both horizontal and vertical binocular disparities produce depth perception in adults. In developmental studies, infants aged around 4 to 6 months were shown to perceive depth from horizontal disparity. However, infants' sensitivity to vertical disparity has not been shown clearly. To examine the sensitivity in infants, this study measured preferential looking behavior of infants aged 20 to 27 weeks. Results showed a significant preference for the stimulus with vertical disparity, providing the first evidence of infants' sensitivity to vertical disparity. The infants in the same age group did not show preference for stimulus with horizontal disparity when the stimulus were comparable to the stimulus with vertical disparity, while their sensitivity to horizontal disparity was confirmed with the stimuli used in a previous study. Our results would suggest that properties in processing horizontal and vertical disparities are different in infancy, and that the sensitivity to horizontal disparity are still premature in 27 weeks after birth.

    To determine the developmental outcome of premature infants weighing 1,750 gm or less at birth and who had grade III intraventricular hemorrhage (IVH), we followed up ten infants with IVH confirmed by computed tomography (CT) and ten CT-negative control infants until they were 12 months corrected age. The infants were evaluated at three-month intervals with neurologic examinations; hearing, speech, and language assessments; Bayley testing; and evoked response studies. Normal criteria were defined in each area. Eight of ten grade III IVH survivors had identifiable defects, with a predominance of motor deficits, as assessed by two or more parameters. Only three of the ten patients without IVH had two or more suspicious or abnormal assessments. Infants with grade III IVH may have widespread damage. Use of CT in these infants has permitted early diagnosis, with accurate assessment of the severity of the hemorrhage and prompt neurosurgical treatment.

    Improvements in the care of the premature infant and advancements in technology are increasing life expectancy of infants with medical conditions once considered lethal; these infants are at risk of becoming a medically complex infant. Complex infants have a significant existing problem list, are on several medications, and receive medical care by several specialists. Deficits in communication and information transfer at the time of discharge remain problematic for this population. A questionnaire was developed for primary care providers (PCPs) to explore the effectiveness of the current discharge summary because it is related to effective communication when assuming the care of a new patient with medical complexity. PCPs assuming the care of these infants agree that an evidence-based tool, in the form of a specialized summary for this population, would be of value. PMID:24985113

    Research investigating the efficacy of infant massage has largely focused on premature and low birth weight infants. The majority of investigations have neglected highly acute patients in academic neonatal intensive care units (NICUs). The current study was developed with two aims: (Phase 1) to develop, implement and demonstrate the feasibility and safety of a parent-trained compassionate touch/massage program for infants with complex medical conditions and (Phase 2) to conduct a longitudinal randomized control trial (RCT) of hand containment/massage versus standard of care in a level III academic Center for Newborn and Infant Critical Care (CNICC). Certified infant massage instructors (CIMIs) taught parents to massage their hospitalized infants. Massage therapy and instruction were performed for seven consecutive days and health outcomes were collected for up to 1 month following treatment. Caregivers, nurses and certified infant massage therapists indicated moderate to high levels of satisfaction and feasibility with the implementation of hand containment/massage in a level III academic center CNICC. In addition, infant behavioral and physiological measures were within safe limits during the massage sessions. All caregivers participating in the massage group reported high levels of satisfaction 7 days into the intervention and at the 1-month follow-up with regards to their relationship with their infant, the massage program's impact on that relationship and the massage program. Due to unequal and small sample sizes, between group analyses (control versus massage) were not conducted. Descriptive infant characteristics of health outcomes are described. Preliminary data from this study indicates feasibility and safety of infant massage and satisfaction among the caregivers, CIMIs and the nurses in the CNICC. An important contribution from this study was the demonstration of the infants' safety based on physiological stability and no change in agitation/pain scores

    Purpose. With many preterm babies now surviving as a result of improvement in neonatal care in Nigeria, the incidence of visual impairment/blindness as a result of retinopathy of prematurity (ROP) may rise. We describe our findings after screening starts for the first time in a 15-year-old special care baby unit so as to establish the incidence and risk factors for developing ROP. Methods. A prospective study carried out at the Special Care Baby Unit (SCBU) and Pediatric Outpatient Clinics of the University of Port Harcourt Teaching Hospital between January 1 and October 31, 2012. Fifty-three preterm babies (of 550 neonates admitted within the study period) delivered before 32 completed weeks and weighing less than 1500 g were included in the study following informed consent and the main outcome measure was the development of any stage of ROP. Results. Mean gestational age at birth was 28.98 ± 1.38 weeks. Mean birth weight was 1411 ± 128 g. Out of 550 babies admitted at SCBU, 87 of 100 preterms survived with 53 included in study. Twenty-five (47.2%) had different degrees of ROP with prevalence found to be 47.2%. Prevalence was higher (75%) in babies weighing <1300 g and those delivered before 30-week gestation (58%). Twenty-one (84%) had stage 1 no plus disease and 3 (12%) had stage 2 no plus disease. Only 1 (4%) had threshold disease in Zone 1. None had disease at stage 4 or 5 or AP-ROP. Receiving supplemental oxygen (χ (2) = 6.17; P = 0.01), presence of sepsis (χ (2) = 7.47; P = 0.006), multiple blood transfusions (χ (2) = 5.11; P = 0.02), and delivery by caesarian section (χ (2) = 4.22; P = 0.04) were significantly associated with development of ROP. There were no significant differences with gender, apneic spells, jaundice, or phototherapy. Conclusions and Relevance. All live infants with ROP were noted to regress spontaneously in this study.

    Background Tandem mass spectrometry has been proposed as a method of diagnosing or predicting the development of common complex neonatal diseases. Our objective was to identify metabolites associated with common complications of prematurity. Methods We performed a retrospective analysis of medical data and metabolite measurements from routine neonatal screening on 689 preterm (<37 weeks of gestational age) neonates. Results We observed higher levels of phenylalanine in infants with respiratory distress syndrome (RDS; P=1.7×10−5), the only association that was significant after correction for multiple testing. We found suggestive significance (P<0.001) of higher essential amino acids in infants with patent ductus arteriosus (PDA). Functionality of these findings was explored in the ductus arteriosus (DA) isolated from term and preterm mouse pups. None of the amino acids had a direct vasodilatory effect on the isolated DA. Conclusion We found newborns with RDS had higher levels of phenylalanine that may be due to impaired phenylalanine hydroxylase activity. We also detected marginally higher levels of all measured essential amino acids in infants with PDA. We did not find dilation of the mouse ductus for these metabolites indicating that instead of potentially causing PDA they are likely serving as markers of catabolism. PMID:23481552

  7. Infant mortality rates declining, but still high.

    Family planning can improve infant survival. Specifically, use of family planning methods can minimize family size, increase birth spacing, and reduce the likelihood of pregnancy for teenagers and women aged 40 or older. Immunizations and oral rehydration are responsible for the falling infant mortality rats since 1977 in developing countries, especially among 1-12 month old infants. Yet, neonatal mortality in developing countries had not changed. WHO intends to step up efforts to improve newborn survival. Accurate data are needed, however. Even in developed countries which keep good statistics, infant mortality bias exists. For example, in Japan, some infant deaths are called fetal deaths. In developing countries, much of the data come from hospitals, yet most birth do not occur in hospitals. Even in surveys, bias exists, such as problems with recall. Many researchers use traditional birth attendants (TBAs) to follow up on all births in an area which may eliminate some biases. Such a prospective and longitudinal study in Trairi county in northeastern Brazil shows the infant mortality rate to be less than half of the official rate (65 vs. 142). The major causes of infant death in developed countries, which tends to occur in the neonatal period, are low birth weight, prematurity, birth complications, and congenital defects; developing countries; they are vaccine preventable infectious diseases, diarrhea and dehydration, and respiratory illnesses, all complicated by malnutrition. To make further strides in reducing infant mortality, public health workers must concentrate on the neonatal period. Training TBAs in sterile techniques, appropriate technology, resuscitation of infants, and identification of potential problems is a positive step. Yet, unpredictable conditions (e.g., AIDS) exist and/or will arise which erode improvements. For example, in Nicaragua, within 1 year after the new government introduced health budget cuts which resulted in the poor paying for

  8. The low-birth-weight infant

    PubMed Central

    1989-01-01

    Low-birth-weight (LBW) infants have special nutritional requirements arising from their rapid growth rate and developmental immaturity. LBW infants are of many kinds; for example, the nutritional needs and functional capabilities of a small-for-gestational-age full-term infant are not the same as those of a very LBW premature infant. Ideal criteria for evaluating the nutritional management of these infants have not been established, and thus the recommended intakes given here do not represent proven physiological requirements. They nevertheless provide a basis from which more refined recommendations may be made. Although this chapter is not intended as such to be a discussion of applicable feeding techniques, it would be difficult and artificial to divorce two such closely intertwined aspects of the distinctive needs of this highly vulnerable group. Feeding techniques have to be carefully assessed in the light of specific environments and the expertise available, and none is entirely risk-free in any setting. Thus, it is essential to compensate for the immaturity of the infants and to avoid compromising the airway or risking aspiration of gastric contents. The choice between using breast milk or proprietary formulas in feeding LBW infants is complex on both nutritional and immunological grounds as well as for practical reasons. Given that the preponderance (>90%) of LBW infants are born in developing countries, the use of an infant's own mother's fresh milk may be the only realistic option. However, irrespective of the health care facilities, level of technology or alternative formulas that might be available, studies show that there is much to recommend feeding LBW infants their own mothers' milk in any environment.

    Bronchopulmonary dysplasia (BPD) is a common long-term complication in premature newborns requiring ventilatory support and is the most common cause of chronic diffuse lung disease in this population. We present the clinical course of a premature newborn with a complicated neonatal respiratory course that was initially thought to be related to BPD, but it did not respond to the typical therapies for this condition. Due to the findings of periventricular nodular heterotopia, the diagnosis of a filamin A gene mutation was eventually made, which explained the respiratory pathology of this patient. When time of onset and clinical course do not correlate with typical BPD, one should consider alternative diagnoses in premature infants, including neonatal diffuse lung disease. PMID:25053830

    Premature ejaculation (PE) subjectively affects 20-30% of men globally. Until recently, understanding of PE was hampered by the absence of a widely accepted definition, paucity of evidence-based clinical studies, and the absence of an appropriate animal model. Here, we elaborate on the current definition of PE, its pathogenesis, currently available therapies, and future treatment prospects. Most treatments for PE are 'off-label' and include selective serotonin reuptake inhibitors (SSRIs), topical anesthetics, tramadol, and phosphodiesterase type 5 (PDE5) inhibitors. Such knowledge of the benefit and limitations of each treatment will help to direct future drug design and formulations. PMID:27179987

    Background: The microbial colonization of the neonatal gut provides a critical stimulus for normal maturation and development. This process of early microbiota establishment, known to be affected by several factors, constitutes an important determinant for later health. Methods: We studied the establishment of the microbiota in preterm and full-term infants and the impact of perinatal antibiotics upon this process in premature babies. To this end, 16S rRNA gene sequence-based microbiota assessment was performed at phylum level and functional inference analyses were conducted. Moreover, the levels of the main intestinal microbial metabolites, the short-chain fatty acids (SCFA) acetate, propionate and butyrate, were measured by Gas-Chromatography Flame ionization/Mass spectrometry detection. Results: Prematurity affects microbiota composition at phylum level, leading to increases of Proteobacteria and reduction of other intestinal microorganisms. Perinatal antibiotic use further affected the microbiota of the preterm infant. These changes involved a concomitant alteration in the levels of intestinal SCFA. Moreover, functional inference analyses allowed for identifying metabolic pathways potentially affected by prematurity and perinatal antibiotics use. Conclusion: A deficiency or delay in the establishment of normal microbiota function seems to be present in preterm infants. Perinatal antibiotic use, such as intrapartum prophylaxis, affected the early life microbiota establishment in preterm newborns, which may have consequences for later health. PMID:27136545

    Premature ejaculation is the most frequent male sexual dysfunction, estimated to affect 20 to 30% of men at some time in their life. A Pubmed search from the year 2000 to the present was performed to retrieve publications related to management or treatment of premature ejaculation. Behavioral techniques have been the mainstay of premature ejaculation management for many years, although evidence of their short-term efficacy is limited. Topical therapies for premature ejaculation act by desensitizing the penis and do not alter the sensation of ejaculation. Selective serotonin reuptake inhibitors (SSRIs), commonly used in the treatment of depression, are often used to treat premature ejaculation, based on the observation that delayed ejaculation is a frequent side effect of this drug class. Dapoxetine is a short-acting SSRI formulated to treat premature ejaculation, and results seem very promising. PMID:26761263

    Premature birth is a serious problem of public health around the world owing to the high frequency of complications and perinatal losses. According to the WHO recommendations by gestation terms the premature birth divides into: super early premature birth (SEPB) in the term of 22-27 weeks, early PB in the term of 28-33 weeks and PB in the term of 34-37 weeks. Preterm born infants make 85%, and in the neonatal mortality structure make more than 55%. It is necessary to consider that in recent years the number of women in the premature birth development risk group has increased, to which patients with a uterus scar, extragenital pathology, supporting reproductive technology treatment pregnancy are related.

    Over the past several years, many advances have been made in our understanding of the epidemiology, pathophysiology, and management of premature ejaculation. Newly developed definitions of premature ejaculation are now available, and our perception of the classification, prevalence, aetiological factors, and treatment options for premature ejaculation have evolved. Despite ongoing research, there remains much to be learned about all aspects of this common sexual disorder, in particular effective clinical diagnosis and treatment options. PMID:26502991

    When infants are born at the borderline of viability, doctors and parents have to make tough decisions about whether to institute intensive care or provide only palliative care. Often, these decisions are made in moments of profound emotional turmoil, and parents receive different information from different health professionals. Communication can become garbled. It may be difficult to tell when and whether the patient's clinical condition has changed enough so that certain choices that had once been permissible become impermissible. In this "Ethics Rounds," we present a case of triplets born at the borderline of viability. We sought comments from the triplets' parents, the doctors and ethicist who were caring for the infants, and a bioethicist/neonatologist from another hospital. PMID:26738882

    A risk-approach-strategy project sponsored by WHO was undertaken in 22 villages of Surur, Pune, by BJ Medical College. All births in the study population of 47,000 were followed, comparing the 3 cohorts born between January 1981 to December 1983. Female village health guides were trained in screening for 11 maternal risk factors, infant risk factors, infant monitoring, and basic health support such as maternal nutrition, rest, breastfeeding and home cleaning, heating, humidifying and infant isolation. There were 123, 97 and 87 infant deaths in the 1981, 1982, and 1983 cohorts, giving infant mortality rats of 91.2, 72.3 and 67.3 respectively. The proportion of neonatal deaths remained at 61 to 62.1% over the period. The most common risk factors seen were illness, low birth weight and growth retardation, often associated with illness. Incidence of low birth weight and prolonged labor both decreased significantly over the duration of the program. Mortality was high among infants with feeding problems and prematurity. 40% of deaths were due to infections, 28% to low birth weight and prematurity, and 9% to birth asphyxia. The lower infant mortality rate achieved here is comparable to urban levels reported in India. These results show that primary health workers are capable of referring and managing risks, and risk management could be applied on a larger scale. PMID:3443502

    2004-09-01

    The potential benefits of a predominantly lactic acid bacterial flora include an improved balance of gut microbial ecology and decreased susceptibility of the gut mucosa to bacterial translocation via adherence to the intestinal mucosa, strengthening mucosal barrier function. These properties should be especially beneficial to the premature neonate with (1) delayed establishment of nor-mal flora, increasing the potential for proliferation of pathogenic bacteria and (2) immature development of the intestinal mucosa, rendering it more susceptible to the translocation of these pathogenic bacteria and leading to extra-intestinal spread and systemic disease. Early probiotic supplementation in preterm infants is theoretically sound and associated with minimal risk. Clinical data remain preliminary but are supportive of a reduction in feeding intolerance and NEC in this high-risk group. PMID:15325534

    Preterm infant tidal breathing may be different from that of healthy full-term infants because of various features of the premature thorax. The purpose of this project was to describe chest wall motion in the preterm infant (gestational age <37 weeks) and compare it with chest wall motion data in a group of healthy, full-term infants. We wanted to use an objective bedside method for assessment with minimal disruption to the infant. The study population consisted of 61 preterm human infants whose mean(+/-sD) postconceptional age at time of study was 35.3+/-2.1 weeks. During the study, the infants were quietly awake in a prone position. Preterm infants had initially been admitted to a level III neonatal intensive care unit for acute management and had been transferred to a step-down area, where they were in stable condition for study. Data were collected with a semiquantitatively calibrated, noninvasive respiratory inductive plethysmograph. Mean(+/-SD) phase angle was significantly greater in preterm infants than in full-term infants (60.6+/-39.8 degrees versus 12.5+/-5.0 degrees, respectively, p < or = 0.0001). The laboured breathing index was significantly greater in preterm infants than in full-term infants (1.35+/-0.35 versus 1.01+/-0.01, respectively, p = 0.001). The ribcage contribution to breathing did not differ significantly between preterm and full-term infants (25.5+/-17.7% versus 36.3+/-14.4%, respectively, p = 0.11). These results indicate a significant increase in the degree of ribcage and abdomen asynchrony in the preterm subjects compared to the full-term infants. Plethysmography provided a time-efficient and objective method of assessing chest wall motion in this fragile population. PMID:9387956

    PubMed

    Baudon, J-J

    2009-05-01

    Gastroesophageal reflux (GER) is a common problem in infants but the distinction between GER and GER disease remains difficult. Clinical manifestations such as vomiting, poor weight gain, respiratory disorders, and apneas do always not correlate with the demonstration of reflux episodes. Premature infants frequently suffer from reflux but correlations with apneas are also poor. Esophagitis is a complication suggested in infants experiencing pain but reflux by itself can induce pain as well. The "gold" diagnosis test is pH recording; however, overlap between normal and abnormal indices is obvious. Impedance measurement demonstrates more reflux episodes but non-acid reflux harm is not established. GER disease is probably self-limited in most infants, although it is impossible to predict whether some of them continue to have GER in adult life. The treatment raises doubts concerning indications and efficacy. Overprescription is frequent in infants with regurgitations. Nonpharmacological treatment - small-volume thickened milk and correct positioning - should be the first-line treatment. Prokinetic drugs have not proved their efficacy. Among anti-acid drugs, proton pump inhibitors are the best choice, but their indications are not very clearly established for infants. On the other hand, considerable variations of their metabolism due to the patients' age and genetic factors can explain variations in therapeutic effects. PMID:19303264

    Sighs are thought to play an important role in control of breathing. It is unclear how sighs are triggered, and whether preterm birth and lung disease influence breathing pattern prior to and after a sigh in infants. To assess whether frequency, morphology, size, and short-term variability in tidal volume (VT) before, during, and after a sigh are influenced by gestational age at birth and lung disease (bronchopulmonary dysplasia, BPD) in former preterm infants and healthy term controls measured at equivalent postconceptional age (PCA). We performed tidal breathing measurements in 143 infants during quiet natural sleep at a mean (SD) PCA of 44.8 (1.3) weeks. A total of 233 sighs were analyzed using multilevel, multivariable regression. Sigh frequency in preterm infants increased with the degree of prematurity and severity of BPD, but was not different from that of term controls when normalized to respiratory rate. After a sigh, VT decreased remarkably in all infants (paired t-test: P < 0.001). There was no major effect of prematurity or BPD on various indices of sigh morphology and changes in VT prior to or after a sigh. Short-term variability in VT modestly increased with maturity at birth and infants with BPD showed an earlier return to baseline variability in VT following a sigh. In early infancy, sigh-induced changes in breathing pattern are moderately influenced by prematurity and BPD in preterm infants. The major determinants of sigh-related breathing pattern in these infants remain to be investigated, ideally using a longitudinal study design. PMID:26564066

    For many years soy bean-based formulas (SBBF) were the only dietary product used for infants with cow's milk intolerance. At the present time, their place in infant nutrition is reduced as a result of the availability of new dietary products without lactose and/or cow's milk proteins and the recognition of soy bean protein allergy. There is no evidence that SBBF have any efficiency in infant colic. SBBF have no indication in the prevention of allergy, nor in premature infants' nutrition. Their main indication is the feeding of infants of vegetarian parents who do not want to use cow's milk products. Studies have shown that SBBF contain large quantities of phytoestrogens, particularly isoflavone. Because of experimental data suggesting a possible deleterious effect of phytoestrogens on the neuroendocrine maturation, the reduction of their content in SBBF must be considered. PMID:11760676

    Objective. The goals were to isolate and study the genetic susceptibility to retinopathy of prematurity (ROP), as well as the gene-environment interaction established in this disease. Methods. A retrospective study (2000–2014) was performed about the heritability of retinopathy of prematurity in 257 infants who were born at a gestational age of ≤32 weeks. The ROP was studied and treated by a single pediatric ophthalmologist. A binary logistic regression analysis was completed between the presence or absence of ROP and the predictor variables. Results. Data obtained from 38 monozygotic twins, 66 dizygotic twins, and 153 of simple birth were analyzed. The clinical features of the cohorts of monozygotic and dizygotic twins were not significantly different. Genetic factors represented 72.8% of the variability in the stage of ROP, environmental factors 23.08%, and random factors 4.12%. The environmental variables representing the highest risk of ROP were the number of days of tracheal intubation (p < 0.001), postnatal weight gain (p = 0.001), and development of sepsis (p = 0.0014). Conclusion. The heritability of ROP was found to be 0.73. The environmental factors regulate and modify the expression of the genetic code. PMID:26089603

    There is growing support for the role of genetic factors in the development of retinopathy of prematurity (ROP), a serious visual morbidity resulting from preterm birth. We used both candidate gene and data-mining approaches to investigate the role of genetic polymorphisms in the development of ROP. Our study population consisted of 330 infants, less than 32 wk gestation, and their parents. We initially studied 24 single nucleotide polymorphisms (SNPs) in 11 candidate genes. Using a family-based analysis strategy, we found an association between SNPs in the EPAS1 gene and the development of ROP (p = 0.007). Logistic regression analysis showed three SNPs associated with development of ROP, two in the CFH gene (p = 0.01) and one in the EPAS1 gene (p = 0.001). Extending this analysis to include genotyping data from a larger genetic study of prematurity (455 SNPs in 153 genes), we found SNPs in five genes associated with the development of ROP: IHH (p = 0.003), AGTR1 (p = 0.005), TBX5 (p = 0.003), CETP (p = 0.004), and GP1BA (p = 0.005). Our data suggest that genetic risk factors contribute to the development of ROP. PMID:18787502

    Strategies, recommendations and techniques proposed by sex therapy for intervention on premature ejaculation, have represented for nearly four decades the most effective model of intervention in this sexual dysfunction, which currently is complemented by the efficacy of dapoxetine drug treatment. Clinical experience and recent studies support that combined intervention offers the best therapeutic results. In addition in sex therapy, etiologic diagnosis is obtained from the analysis of the interrelationship of the couple. Diagnostic and therapeutic intervention has to be always centered in the relationship, so the techniques and resources must be applied with the expectation of being implemented in the sexual interaction. It will therefore be the relationship that receive treatment, even if medication is used for one of the members of the couple. On the other hand, this model of intervention can be implemented by a professional with training, although not necessarily a specialist. PMID:25953038

    This study forms part of a longitudinal investigation of early infant social withdrawal, maternal symptoms of depression and later child social emotional functioning. The sample consisted of a group of full-term infants (N=238) and their mothers, and a group of moderately premature infants (N=64) and their mothers. At 3 months, the infants were observed with the Alarm Distress Baby Scale (ADBB) and the mothers completed the Edinburgh Postnatal Depression Scale (EPDS). At 12 months, the mothers filled out questionnaires about the infants' social emotional functioning (Infant Toddler Social Emotional Assessment and the Ages and Stages Questionnaire-Social Emotional). At 3 months, as we have previously shown, the premature infants had exhibited more withdrawal behavior and their mothers reported elevated maternal depressive symptoms as compared with the full-born group. At 12 months the mothers of the premature infants reported more child internalizing behavior. These data suggest that infant withdrawal behavior as well as maternal depressive mood may serve as sensitive indices of early risk status. Further, the results suggest that early maternal depressive symptoms are a salient predictor of later child social emotional functioning. However, neither early infant withdrawal behavior, nor gestational age, did significantly predict social emotional outcome at 12 months. It should be noted that the differences in strength of the relations between ADBB and EPDS, respectively, to the outcome at 12 months was modest. An implication of the study is that clinicians should be aware of the complex interplay between early infant withdrawal and signs of maternal postpartum depression in planning ports of entry for early intervention.

    The present study analyzed the links between prematurity, attention, and global cognitive performance in infancy and early childhood. At 7 months, focused attention (FA) was examined with an object examination task in 93 preterm infants (39 of them born extremely/very preterm, 54 born moderately/late preterm, and 38 infants born full-term). Global cognition was assessed at 7 and 24 months with the Bayley-II cognitive scale. Groups did not differ with respect to global cognitive performance but FA of infants born extremely/very preterm was significantly lower than in infants born moderately/late preterm. FA correlated significantly with both prematurity and cognitive performance at 7 months of age but not with global cognition in childhood. Findings point to a subtle adverse effect of prematurity on early attention and reveal evidence for the mediating role of FA on the effect of prematurity on cognition. PMID:24697340

    Sudden infant death syndrome (SIDS) is the leading cause of death among infants aged 1 to 12 months. In this article, we review risk factors that may predispose infants to increased vulnerability. Maternal characteristics, including nonmodifiable and modifiable factors, antenatal medical conditions, labor and delivery events, and infant characteristics, are reviewed, with the purpose of helping obstetric care providers target risk reduction efforts. We have reviewed over 85 case-control, retrospective, and prospective cohort studies published between 1975 and 2011. Major modifiable risk factors include maternal and paternal smoking, drug use, alcohol use, and insufficient prenatal care. Infants at increased risk include males, premature infants, infants of low birth weight or growth-restricted infants, and infants in multiple gestations. By targeting modifiable and nonmodifiable risk factors, it may be possible to decrease the incidence of SIDS. Efforts should be put on decreasing high-risk behaviors and encouraging sufficient antenatal follow-up. In view of recent increases in ethnic and social disparity with SIDS, it is essential that risk reduction guidelines, which have recently been expanded by the American Association of Pediatrics, be explained in a culturally sensitive manner.

    We have investigated the effects of iodine (I) intake on urinary I excretion in preterm (PT) babies up to 2 months after birth and its effect on serum T4, free T4 (FT4), T3, TSH, and thyroglobulin (Tg) levels compared to those in term (T) newborns. Very premature and very sick infants were in negative I balance for the first weeks after birth. Later, these same infants, as well as the other PT and T newborns, were in positive balance; 75- 80% of the ingested I was not accounted for in the urine. The urinary I levels of PT and T neonates cannot be equated to their I intakes. T4, FT4, and T3 levels in PT and T neonates increased with postmenstrual age, whereas Tg decreased and TSH did not change. Serum FT4, T3, Tg, and TSH levels in PT neonates were affected negatively, independently from age, by a low I intake. PT birth also affected T4, FT4, and Tg negatively, independently from I intake and postmenstrual age, for at least 6-8 weeks after birth. Care should be taken to avoid I deficiency in PT neonates. However, even when I intake is adequate, PT newborns are hypothyroxinemic compared to T babies during an important period of brain development. This suggests the possible convenience of interventions that might mimic the intrauterine hormone environment and accelerate maturation. PMID:9177368

    Objective  Despite the current prevalence of preterm births, no clear guidelines exist on the optimal mode of delivery. Our objective was to investigate the effects of mode of delivery on neonatal outcomes among premature infants in a large cohort. Study Design  We applied a retrospective cohort study design to a database of 6,408 births. Neonates were stratified by birth weight and a composite score was calculated to assess neonatal outcomes. The results were then further stratified by fetal exposure to antenatal steroids, birth weight, and mode of delivery. Results  No improvement in neonatal outcome with cesarean delivery (CD) was noted when subjects were stratified by mode of delivery, both in the presence or absence of antenatal corticosteroid administration. In the 1,500 to 1,999 g subgroup, there appears to be an increased risk of respiratory distress syndromes in neonates born by CD. Conclusion  In our all-comers cohort, replicative of everyday obstetric practice, CD did not improve neonatal outcomes in preterm infants. PMID:27468363

    Ecthyma gangrenosum is a well-recognised cutaneous infection in critically ill and immunocompromised patients. It is commonly associated with Pseudomonas aeruginosa septicaemia. Classic lesions of ecthyma gangrenosum comprise deep ulcers with ecchymotic, gangrenous centres, bright red areolae and typical raised, purplish, indurated, rolled-out edges. We report ecthyma gangrenosum in a premature low-birth-weight neonate, delivered at home to a third gravida mother with history of chorioamnionitis. He was admitted to a private hospital on third day of life, with a diagnosis of early-onset neonatal sepsis and received multiple antibiotics over next 22 days. The infant was referred to the paediatrics emergency department of Sir Sunderlal Hospital, Banaras Hindu University in a condition of shock, pneumonitis and generalised sepsis. Two gangrenous ulcers with gray-black eschar were present, one over the neck and another over the back. He was diagnosed as a case of neonatal sepsis with ecthyma gangrenosum. Blood culture revealed growth of Pseudomonas aeruginosa, sensitive only to imipenem. The infant died the day following admission. PMID:22240885

  1. Development of infant oral feeding skills: what do we know?

    PubMed

    2016-02-01

    The hospital discharge of premature infants in neonatal intensive care units is often delayed due to their inability to feed by mouth safely and competently. With immature physiologic functions, infants born prematurely cannot be expected to readily feed by mouth at the equivalent age of a third trimester of gestation as the majority of their term counterparts do. Consequently, it is crucial that health care professionals gain an adequate knowledge of the development of preterm infants' oral feeding skills so as to optimize their safety and competency as they transition to oral feeding. With a greater sensitivity toward their immature skills, we can offer these infants a safer and smoother transition to independent oral feeding than is currently observed. This review article is an overview of the evidence-based research undertaken over the past 2 decades on the development of very-low-birth-weight infants' oral feeding skills. The description of the different functional levels where these infants can encounter hurdles may assist caregivers in identifying a potential cause or causes for their individual patients' oral feeding difficulties.

    Skin-to-skin care involves the mother placing her diaper-clad infant upright between her breasts in direct skin contact. The practice has evolved worldwide to be an intervention strategy in neonatal intensive care units for premature infants and their mothers. Few adverse outcomes have been noted in thermoregulation, cardiovascular changes, or behavioral organization. Findings have been positively related to better infant physiologic and neurobehavioral outcomes, maternal breastfeeding success, and positive attachment relationships. The early, intimate, and physiologically stabilizing benefits of skin-to-skin care provide for a new conceptualization of the optimal environment for preterm infants in intensive care. PMID:15289033

    This study tested the hypothesis, suggested by several recent reports, that air pollution may increase the risk of adverse birth outcomes. This study analyzed all singleton live births registered by the Czech national birth register in 1991 in 67 districts where at least one pollutant was monitored in 1990-1991 (n = 108,173). Maternal exposures to sulfur dioxide (SO(2)), total suspended particles (TSP), and nitrous oxides (NO(x)) in each trimester of pregnancy were estimated as the arithmetic means of all daily measurements taken by all monitors in the district of birth of each infant. Odds ratios of low birth weight (< 2,500 g), prematurity (< 37 weeks of gestation), and intrauterine growth retardation (IUGR; < 10th percentile of birth weight for gestational age and sex) were estimated by robust logistic regression. The median (and 25th and 75th percentile) trimester exposures were 32 (18, 56) microg/m(3) for SO(2); 72 (55, 87) microg/m(3) for TSP; and 38 (23, 59) microg/m(3) for NO(x). Low birth weight (prevalence 5.2%) and prematurity (prevalence 4.8%) were associated with SO(2) and somewhat less strongly with TSP. IUGR was not associated with any pollutant. The effects on low birth weight and prematurity were marginally stronger for exposures in the first trimester, and were not attenuated at all by adjustment for socioeconomic factors or the month of birth. Adjusted odds ratios of low birth weight were 1.20 [95% confidence interval (CI), 1.11-1.30] and 1.15 (CI, 1.07-1.24) for a 50 microg/m(3) increase in SO(2) and TSP, respectively, in the first trimester; adjusted odds ratios of prematurity were 1.27 (CI, 1.16-1.39) and 1.18 (CI, 1.05-1.31) for a 50 microg/m(3) increase in SO(2) and TSP, respectively, in the first trimester. Low gestational age accounted for the association between SO(2) and low birth weight. These findings provide further support for the hypothesis that air pollution can affect the outcome of pregnancy.

    Background This study aims to investigate the incidence and the relative risk factors of retinopathy of prematurity (ROP) and posterior-ROP (P-ROP): ROP in Zone I and posterior Zone II, as well as to analyze the occurrence of surgical treatment of ROP and to evaluate the short term outcome of the disease in Italy. Methods It is a prospective multicenter observational study; all infants with a birth weight (BW) ≤ 750 g and/or a gestational age (GA) ≤27 weeks born between January 1st 2008 and December 31st 2009 in 25 III level Italian neonatal intensive care units were eligible for the study. Results 421 infants were examined: 265 (62.9%) developed ROP and 102 (24.2%) P-ROP. Following the multivariate analysis erythropoietin-therapy (p < 0.0001) and intraventricular hemorrhage (IVH) (p = 0.003) were significantly associated with ROP while gestational age ≤24 weeks (p = 0.011) and sepsis (p = 0.002) were associated with the onset of P-ROP. Eighty nine infants (34%) required surgical treatment; following the multivariate analysis P-ROP was an independent factor associated with the need of surgical treatment (p < 0.0001). A favorable outcome was reported in 251 (94.7%) newborns affected by ROP. Adverse outcome occurred in 14 patients: all of them underwent surgery and showed P-ROP. Conclusions P-ROP is the most aggressive type of ROP. It associates with lower GA and sepsis. Obstetricians and Neonatologists must focus on the reduction of severe preterm births and on the prevention of neonatal early and late onset sepsis in order to reduce the incidence of P-ROP.

    Social, cultural and economic factors, beside medical causes, contribute to the high percentage of infant mortality in India. This study was carried out in 12 villages in the area of the Rural Health Training Centre, Naila, India; all villages were being regularly visited by paramedical staff and doctors. During 1977 62 infants died. Most parents were illiterate and very poor. 50.3% of deaths occurred within the first 28 days of life, and 25.8% within the first 7 days of life; 72.8% of deaths occurred within the first 6 months of life. Infections and malnutrition accounted for 77.3% of all deaths; pneumonia alone claimed 25.8% of lives, malnutrition 19.3%, fever for unknown reasons 16.1%, diarrhea 14.5% and prematurity 12.9%. Deaths for pneumonia were 56.3% in the postneonatal period and 43.7% in the neonatal period, while fever predominated as a cause of death in the neonatal rather than in postneonatal period, with 70% and 30% of deaths respectively. 56.4% of deaths were recorded among children born to mothers aged 21-30, 30.7% among children of mothers over 30, and 12.9% among children of mothers below 20. 51.6% of dead children had a birth order of 5 and over; only 17.8% had first birth order. 50.1% of deaths were observed in infants who were born less than 12 months from the previous conception. Similar studies done in other Indian regions show similar percentages of infant mortality and of causes for mortality. PMID:7263000

    Background The frequency of preterm labour has risen over the last few years. Hence, there is growing interest in the identification of markers that may facilitate prediction and prevention of premature birth complications. Here, we studied the association of the number of circulating stem cell populations with the incidence of complications typical of prematurity. Methods The study groups consisted of 90 preterm (23–36 weeks of gestational age) and 52 full-term (37–41 weeks) infants. Non-hematopoietic stem cells (non-HSCs; CD45-lin-CD184+), enriched in very small embryonic-like stem cells (VSELs), expressing pluripotent (Oct-4, Nanog), early neural (β-III-tubulin), and oligodendrocyte lineage (Olig-1) genes as well as hematopoietic stem cells (HSCs; CD45+lin-CD184+), and circulating stem/progenitor cells (CSPCs; CD133+CD34+; CD133-CD34+) in association with characteristics of prematurity and preterm morbidity were analyzed in cord blood (CB) and peripheral blood (PB) until the sixth week after delivery. Phenotype analysis was performed using flow cytometry methods. Clonogenic assays suitable for detection of human hematopoietic progenitor cells were also applied. The quantitative parameters were compared between groups by the Mann–Whitney test and between time points by the Friedman test. Fisher’s exact test was used for qualitative variables. Results We found that the number of CB non-HSCs/VSELs is inversely associated with the birth weight of preterm infants. More notably, a high number of CB HSCs is strongly associated with a lower risk of prematurity complications including intraventricular hemorrhage, respiratory distress syndrome, infections, and anemia. The number of HSCs remains stable for the first six weeks of postnatal life. Besides, the number of CSPCs in CB is significantly higher in preterm infants than in full-term neonates (p < 0.0001) and extensively decreases in preterm babies during next six weeks after birth. Finally, the growth of

    Premature ejaculation (PE) is the most common male sexual complaint, and may exert a profound negative impact on the man's life and partnership. Using currently available treatment alternatives (e.g., selective serotonin uptake inhibitor, agents acting locally on the penis), PE can be treated in most, but not all patients. However, since long term success rates have been disappointing, and the only approved treatment so far is the short-acting selective serotonin re-uptake inhibitor dapoxetine, there is currently an intensive search for new treatment modalities. Selection of the most promising therapeutic targets from a host of current and potential candidates depends heavily on their roles in the pathophysiology of PE. Possible central nervous targets that will be discussed are serotonin transporters, and CNS receptors for 5-HT(IA) and 5-HT(1B), dopamine, oxytocin, opioids, neurokinin-1, and glutamate. Putative peripheral targets include α(1)-adrenoceptors, phosphodiestrase enzymes, Rho kinases, purinergic (P2X) receptors, and penile sensory nerves. It is clear that exploiting the full therapeutic potential of these targets will require additional basic and clinical research. PMID:21816550

    Premature ejaculation (PE) is a common male sexual dysfunction. Advances in PE research have been hampered owing to a nonstandardized definition of PE, until the definition by the International Society of Sexual Medicine (ISSM) in 2009. Once the diagnosis of PE is established through a thorough history, a variety of medical therapies is available, including tricyclic antidepressants, selective serotonin reuptake inhibitors (SSRIs), centrally acting opiates, phosphodiesterase 5 inhibitors and topical desensitizing creams. Most of these treatments increase the intravaginal ejaculation latency time (IELT) and patient satisfaction scores, with the most convincing evidence for SSRIs and topical creams. Daily SSRIs such as paroxetine, although efficacious, do have a substantial and prolonged side effect profile. Dapoxetine, which is a on-demand SSRI, is the only licensed drug for the treatment of PE, increasing IELT by a factor of 2.5 to 3 with limited and tolerable side effects. In the near future, the topical aerosol PSD502 is due to be licensed for the treatment of PE, increasing IELT by up to a factor of 6 but having minimal local and negligible systemic side effects.

    A case is presented of a premature newborn of 27 weeks gestation and weighing 420 grams who was delivered as a result of a maternal pre-eclampsia and retarded intra-uterine growth. During the 125 days of hospitalisation, an individual care plan based on the Virginia Henderson model was devised and applied to both the child and her parents using NANDA diagnostics, interventions according to the NIC classification, and the expected results according to the NOC classification. The Marjory Gordon functional patterns were used for the initial assessment. By applying the pre-term newborn (PTNB) plan, all their needs were provided and were modified throughout the hospital stay, with new needs that were added to the established ones. These required a continuous assessment with the subsequent adapting of the care plan. Likewise, the care required by the parents varied from the initial grief due to the possible loss of their child to learning the alarm signs and the home care that their child would need. The child was finally discharged weighing 2900 grams and with normal neurological and psychomotor development, although with a lower weight appropriate to her age. Currently, at 2 years old, the child has a normal neurological and psychomotor development, but with weight and size lower than the P(3) percentile. She requires speech therapy treatment due to paralysis of the right vocal cord. PMID:20605104

    In the past few years, there has been an upsurge of interest in aluminum (Al) and human health. The well-recognized manifestations of systemic Al toxicity include fracturing osteomalacia, dialysis encephalopathy, and microcytic hypochromic anemia. The role of Al in causing childhood diseases is also becoming clearer, but the safe plasma level still remains to be determined in newborns, especially in premature newborns, implying that it should be kept low. Premature infants receiving iv fluid therapy show evidence of Al loading. Additionally, the infant-feeding mixtures, especially the soy-based infant formulas, tested may be a significant additional source of Al in the diet of infants with low birthweights, and in infants and in young children with impaired renal function. Careful clinical and biochemical monitoring is warranted to determine whether it will be necessary to eliminate Al contamination of both oral and parenteral preparations used in infants and children who may be at risk for Al intoxication. In this present study, the Al content of infant feeds was measured by electrothermal atomic absorption spectrophotometry, and also compared with those of breast milk, cow's milk, milk powder, and some starches that are commonly used for preparation of infant feed in Turkey. Our results show that Al content of commercially available powdered infant formulas, most of which are imported from Europe, ranged from 1.211 to 10.925 micrograms/g. The mean value was higher than that of breast milk. It was also found that the Al content of cow's milk in various containers was higher than that of breast milk. The highest Al level among cow's milk samples was in the aluminized carton box. PMID:8546886

We used this approach to investigate the hypothesis that premature termination of the intrauterine environment by preterm birth reduces cortical development in a dose-dependent manner, providing a neural substrate for functional impairment. Methods and Findings We analyzed 274 magnetic resonance images that recorded brain growth from 23 to 48 wk of gestation in 113 extremely preterm infants born at 22 to 29 wk of gestation, 63 of whom underwent neurodevelopmental assessment at a median age of 2 y. Cortical surface area was related to cerebral volume by a scaling law with an exponent of 1.29 (95% confidence interval, 1.25–1.33), which was proportional to later neurodevelopmental impairment. Increasing prematurity and male gender were associated with a lower scaling exponent (p < 0.0001) independent of intrauterine or postnatal somatic growth. Conclusions Human brain growth obeys an allometric scaling relation that is disrupted by preterm birth in a dose-dependent, sexually dimorphic fashion that directly parallels the incidence of neurodevelopmental impairments in preterm infants. This result focuses attention on brain growth and cortical development during the weeks following preterm delivery as a neural substrate for neurodevelopmental impairment after premature delivery.

    In this paper we describe the application of folding measures to tracking in vivo cortical brain development in premature neonatal brain anatomy. The outer gray matter and the gray-white matter interface surfaces were extracted from semi-interactively segmented high-resolution T1 MRI data. Nine curvature- and geometric descriptor-based folding measures were applied to six premature infants, aged 28-37 weeks, using a direct voxelwise iso-surface representation. We have shown that using such an approach it is feasible to extract meaningful surfaces of adequate quality from typical clinically acquired neonatal MRI data. We have shown that most of the folding measures, including a new proposed measure, are sensitive to changes in age and therefore applicable in developing a model that tracks development in premature infants. For the first time gyrification measures have been computed on the gray-white matter interface and on cases whose age is representative of a period of intense brain development.

    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.

    Oligosaccharides are abundant in human milk. Production of these highly diverse structures requires significant energy expenditure by the mother and yet these human milk oligosaccharides offer no direct nutritive value to her infant. A primary function of human milk oligosaccharides is to shape the infant’s intestinal microbiota with life-long consequences. Bifidobacterium longum subspecies infantis (B. infantis) is unique among gut bacteria in its prodigious capacity to digest and consume any human milk oligosaccharide structure, the result of a large repertoire of bacterial genes encoding an array of glycosidases and oligosaccharide transporters not found in other bacterial species. In vitro, B. infantis grows better than other bacterial strains in the presence of human milk oligosaccharides, displays anti-inflammatory activity in premature intestinal cells, and decreases intestinal permeability. In premature infants, B. infantis given in combination with human milk increases B. infantis and decreases Enterobacteriaceae in the feces. Probiotics containing B. infantis decrease the risk of necrotizing enterocolitis in premature infants. Colonization with B. infantis is also associated with increased vaccine responses. Probiotic organisms have historically been selected based on ease of production and stability. The advantages of B. infantis, selected through coevolution with human milk glycans, present an opportunity for focused manipulation of the infant intestinal microbiota. PMID:25303277

    To investigate the association between maternal pre-pregnancy obesity, race/ethnicity and prematurity. Retrospective cohort study of maternal deliveries at a single regional center from 2009 to 2010 time period (n = 11,711). Generalized linear models were used for the analysis to estimate an adjusted odds ratio with 95% confidence interval of the association between maternal pre-pregnancy obesity, race/ethnicity and prematurity. Analysis controlled for diabetes, chronic hypertension, previous preterm birth, smoking and insurance status. The demographics of the study population were as follows, race/ethnicity had predominance in the White/Non-Hispanic population with 60.1%, followed by the Black/Non-Hispanic population 24.2%, the Hispanic population with 10.3% and the Asian population with 5.4%. Maternal pre-pregnancy weight showed that the population with a normal body mass index (BMI) was 49.4%, followed by the population being overweight with 26.2%, and last, the population which was obese with 24.4%. Maternal obesity increased the odds of prematurity in the White/Non-Hispanic, Hispanic and Asian population (aOR 1.40, CI 1.12-1.75; aOR 2.20, CI 1.23-3.95; aOR 3.07, CI 1.16-8.13, respectively). Although the Black/Non-Hispanic population prematurity rate remains higher than the other race/ethnicity populations, the Black/Non-Hispanic population did not have an increased odds of prematurity in obese mothers (OR 0.87; CI 0.68-1.19). Unlike White/Non-Hispanic, Asian and Hispanic mothers, normal pre-pregnancy BMI in Black/Non-Hispanic mothers was not associated with lower odds for prematurity. The odds for mothers of the White/Non-Hispanic, Hispanic and Asian populations, for delivering a premature infant, were significantly increased when obese. Analysis controlled for chronic hypertension, diabetes, insurance status, prior preterm birth and smoking. Obesity is a risk factor for prematurity in the White/Non-Hispanic, Asian and Hispanic population, but not for the

    Urinary tract infection (UTI) differs between preterm and older infants and children in terms of prevalence, clinical presentation, causative organism, and rate of underlying renal anomalies. Data on risk factors of UTI in preterm infants are limited. The aim of this study was to characterize UTI both clinically and microbiologically in premature infants and to define possible risk factors and the role of breastfeeding in its development. This case-control study was conducted in a tertiary-care neonatal intensive care unit (NICU) between 1995 and 2003. The study group included all premature infants (<37 weeks' gestation) diagnosed with UTI. Pre-, peri-, and postnatal data on demographic, clinical, laboratory, and imaging variables were collected from the medical records and microbiology laboratory log and compared with a gestational age- and birth weight-matched infants without UTI (control group). The ratio of control infants to cases was 2:1. Of the 6198 premature infants admitted to the NICU during the study period, 56 (0.9%) were included in the study group. The main causative organism was Klebsiella spp. Logistic regression analysis identified gender [odds ratio (OR) 2.96, 95% confidence interval (CI) 1.28-6.85, P < 0.0001] and the presence of a peripheral intravenous catheter on the day of infection to be significantly associated with UTI, while breast milk was associated with a lower risk of infection (OR 0.314, 95% CI 0.140-0.707, P < 0.009).

    To investigate the incidence of Retinopathy of Prematurity (ROP) in Beijing, North China, and to evaluate the effectiveness of different ROP screening criteria, we conducted a prospective cohort study in a single-neonatal intensive care unit (NICU). A total of 2997 premature infants with birth weight (BW) ≤ 2000 g and/or gestational age (GA) ≤ 34 weeks had completed ROP screening. ROP was diagnosed in 356 (11.9%) infants. The mean GA was 30.46 ± 1.98 weeks and the mean BW was 1477.35 ± 371.29 g. Of the 59 (2.0%) infants receiving treatment, the mean GA was 29.37 ± 2.10 weeks, and the mean BW was 1240.80 ± 330.71 g. The incidence of ROP declined from 14.7% in 2009 and 11.1% in 2010 to 9.5% in 2011. The United Kingdom (UK) criteria could reduce the screening number by 40.8%, and 3 infants with type I ROP needing treatment were missed, but none in 2011. The United States (US) criteria could reduce the screening number by 66.5%, and 10 infants with type I ROP needing treatment were missed, including one in 2011. So the UK criteria may be appropriate for screening of ROP in our NICU in 2011. Future multisite epidemiologic studies are required to establish suitable ROP screening criteria in China.

  2. Ontogeny of autonomic regulation in late preterm infants born at 34-37 weeks postmenstrual age.

    Late preterm infants (34-37 weeks postmenstrual age at birth) are intermediate between less mature preterm infants and infants born at 38 weeks or more in regard to autonomic brain stem maturation. Ventilatory responses to CO(2) in preterm infants born at 33 to 36 week are significantly higher than in infants born at 29 to 32 weeks both at 3 to 4 and 10 to 14 days postnatal age, but do not differ from full-term reference levels. The ventilatory response to hypoxia in preterm infants is biphasic; initial transient hyperventilation is followed by a return to baseline and then a decrease below baseline. In infants born at 32 to 37 weeks, parasympathetic maturation appears significantly less than in full-term infants based on diminished increases in high frequency heart rate variability in quiet sleep, suggesting that late preterm infants are still more susceptible to bradycardia than full-term infants. Both the presence and severity of apnea of prematurity progressively decrease the higher the postmenstrual age. Late preterm infants, however, are still at risk, with prevalence rates as high as 10% compared with about 60% in infants born at <1500 g. The incidence of apparent life-threatening events is more common in preterm infants (8-10%) than full-term infants (1% or less). In the Collaborative Home Infant Monitoring Evaluation studies, the frequency of conventional and extreme events in near term infants is intermediate between preterm infants <34 weeks at birth and full-term infants. The relative risk for at least one extreme event in late preterm infants is increased (5.6 and 7.6, respectively, P < 0.008) compared with full-term infants and remains higher until 43 weeks postmenstrual age. The rate for Sudden Infant Death Syndrome in preterm infants born at 33 to 36 weeks is 1.37/1000 live births compared with 0.69 in infants born full term. Affected late preterm infants die at a older mean postmenstrual age compared with less mature infants (48 and 46 weeks

    Objective To identify nutritional and weight gain limitations associated with retinopathy of prematurity (ROP) severity among very preterm newborns. Patients and Methods 1180 infants <28 weeks GA at birth with ROP examination results were grouped and analyzed by quartile of weekly total calorie, carbohydrate, protein, and lipid intake, as well as growth velocity between postnatal days 7 and 28 (adjusted for GA and birth weight Z-score). ROP was categorized by development of no, mild (infants with lowest quartile receipt of lipids (2.1/1.1, 3.8), total calories (2.2/1.4, 3.6), and carbohydrates (1.7/1.1, 2.9). Development of zone 1 ROP was associated with lipid or total calorie intake in the lowest quartile, and development of stage 3 ROP was associated with lowest quartile of total calorie intake. Growth velocity in the lowest quartile was associated with increased risk of any ROP, including type 1 ROP. Conclusion The risk of developing severe ROP in extremely premature infants might be reduced by improving nutritional support, specifically targeting lipids and total calories, and perhaps by improving weight gain.

    The neurodevelopmental outcome of 78 infants with bronchopulmonary dysplasia (BPD) was compared with that of 78 control infants matched for birthweight. To determine the effect of the severity of BPD, 62 infants requiring oxygen at 36 weeks' postmenstrual age (sBPD) were compared with their matched controls. Infants were followed up to 2 years of age, corrected for prematurity, and were classified for neurological impairment, developmental delay, and neurodevelopmental disability. Seventy six (98%) BPD infants and 71 (91%) controls had follow up data available to two years. Neurological impairment, developmental delay, and neurodevelopmental disability occurred more frequently in infants with BPD than in controls but this was not significant. For infants with sBPD, the increased incidence of neurological impairment and definite developmental delay was not significant when compared with the controls, though neurodevelopmental disability occurred more frequently (odds ratio (OR) 3.6: 95% confidence intervals (CI) 1.1-11.8). Predictors of disability in infants with sBPD included periventricular haemorrhage (OR 19.4: 95% CI 4.3-86.6), ventricular dilatation (OR 12.8: 95% CI 2.9-57.3), and sepsis (OR 5.0: 95% CI 1.3-19.4). Adjusting for the presence of these factors, the association between BPD and disability was no longer apparent (OR 0.9: 95% CI 0.2-3.6). The findings suggest that BPD is not independently associated with adverse neurodevelopmental outcome. PMID:8535867

    Intussusception is a very rare cause of intestinal obstruction in neonates. It is of extremely rare occurrence among premature neonates. We present a case of 11-day-old premature neonate who presented with abdominal distension, intolerance to feeds, vomiting, significant bilious aspirate and bleeding per rectum. The initial diagnosis of necrotizing enterocolitis (NEC) led to a delay in the diagnosis. On exploratory laparotomy, it turned out to be a case of ileo-colic intussusception with Meckel's diverticulum as a lead point. This site of intussusception (ileo-colic) and presence of a lead point among premature neonate is of exceedingly rare occurrence and very few such cases have been reported. In this article, the published work about clinical features and management on intussusceptions in premature neonates has been reviewed. The authors intend to highlight the difficulty in distinguishing the NEC and intussusception. Subtle clinical and radiological features which can help in differentiating the two conditions have been emphasized. This can avoid the delay in diagnosis and management which can prove critical. High index of suspicion with timely intervention is the key for optimizing outcome. A diagnosis of intussusception should always be considered in any preterm infant with suspected NEC. PMID:25659559

    Retinopathy of prematurity (ROP) causes 100,000 new cases of childhood blindness each year. ROP is initiated by oxygen supplementation necessary to prevent neonatal death. We used organ systems pharmacology to define the transcriptomes of mice that were cured of oxygen-induced retinopathy (OIR, ROP model) by hypoxia-inducible factor (HIF) stabilization via HIF prolyl hydroxylase inhibition using the isoquinolone Roxadustat or the 2-oxoglutarate analog dimethyloxalylglycine (DMOG). Although both molecules conferred a protective phenotype, gene expression analysis by RNA sequencing found that Roxadustat can prevent OIR by two pathways: direct retinal HIF stabilization and induction of aerobic glycolysis or indirect hepatic HIF-1 stabilization and increased serum angiokines. As predicted by pathway analysis, Roxadustat rescued the hepatic HIF-1 knockout mouse from retinal oxygen toxicity, whereas DMOG could not. The simplicity of systemic treatment that targets both the liver and the eye provides a rationale for protecting the severely premature infant from oxygen toxicity. PMID:27091985

    The management of retinopathy of prematurity (ROP) can be challenging in preterm babies with a gestational age <30 weeks, those with very low birth weight and multiple risk factors (eg., oxygen therapy for respiratory distress, sepsis, neonatal jaundice). A premature infant presented with "hybrid" zone 1 disease in the right eye and aggressive posterior ROP in the left eye. Both eyes were adequately treated with laser photocoagulation; however, the eyes deteriorated and progressed to stage 4 ROP. Both eyes eventually underwent intravitreal bevacizumab followed by lens sparing vitrectomy with good anatomical and visual outcome. Anticipation of progression despite laser photocoagulation in certain clinical scenarios, frequent follow-up and timely surgical intervention is paramount. PMID:26180484

    In a prospective, case-controlled longitudinal design, 180 preterm and fullterm infants who had been enrolled at birth participated in a comprehensive assessment battery at age 23. Of these, 149 young adults, 34 formerly full-term and 115 formerly preterm (22 healthy preterm, 48 with medical complications, 21 with neurological complications, and 24 small for gestational age) donated five saliva samples from a single day that were assayed for cortisol to assess diurnal variation of the hypothalamic-pituitary-adrenal (HPA) axis. Analyses were conducted to determine whether prematurity category, birth weight, and socioeconomic status were associated with differences in HPA axis function. Pre- and perinatal circumstances associated with prematurity influenced the activity of this environmentally sensitive physiological system. Results are consistent with the theory of Developmental Origins of Health and Disease and highlight a possible mechanism for the link between prematurity and health disparities later in life.

    Preterm born children without neurological impairments have been shown to present some visual-manual coordination deficits, more or less depending on their tonicity and the degree of prematurity. In this paper, we compare the development of tool use in 15-23-month-old preterm infants born after 33-36 weeks of gestation without neurological complications with that of full-term infants according to corrected age. Understanding the affordance of a tool is an important cognitive milestone in early sensorimotor period. Using a tool to bring within reach an out-of-reach object, for instance, has been shown to develop during the 2nd year in full-term infants. Here we presented preterm infants with an attractive toy out of reach and with a rake-like tool within reach in five conditions of spatial relationships between the toy and the tool. Like full-terms, preterm infants used the tool with success in conditions of spatial contiguity around 15-17 months. In conditions of a spatial gap between tool and toy, i.e., the only conditions which shows without ambiguity that the infant understands the affordance of the tool, preterm infants as a group showed no delay for tool use: the frequency of spontaneous successes started to increase after 18 months, and demonstration became effective after that age. However, further analyses showed that only the preterm infants without hypotonia and born after 36 weeks of pregnancy developed tool use without delay. Hypotonic preterm infants were still largely unsuccessful in the conditions of spatial gap, even at the end of the study. The degree of prematurity also influenced the performance at tool use. These results, following the observation of a delay in the development of bimanual coordination and of handedness in the same infants at 10-12 months in a previous study, show that low risk preterm infants can still be impaired for the development of new manual skills beyond the 1st year.

    OBJECT Intraventicular hemorrhage (IVH) and posthemorrhagic hydrocephalus (PHH) are common in premature newborns. The epidemiology of these conditions has been described, but selection bias remains a significant concern in many studies. The goal of this study was to review temporal trends in the incidence of IVH, PHH, and shunt surgery in a population-based cohort of very preterm infants with no selection bias. METHODS All very preterm infants (gestational age ≥ 20 and ≤ 30 weeks) born from 1993 onward to residents of Nova Scotia were evaluated by the IWK Health Centre's Perinatal Follow-Up Program, and were entered in a database. Infants born to residents of Nova Scotia from January 1, 1993, to December 31, 2012, were included in this study. The incidences of IVH, PHH, and shunt surgery were calculated, basic demographic information was described, and chi-square test for trends over time was determined. RESULTS Of 1334 successfully resuscitated very preterm infants who survived to their initial screening ultrasound, 407 (31%) had an IVH, and 149 (11%) had an IVH Grade 3 or 4. No patients with IVH Grade 1 or 2 developed PHH. The percentage of very preterm infants with IVH Grade 3 or 4 has significantly increased over time (p = 0.013), as have the incidence of PHH and shunt surgery (p = 0.001 and p = 0.011, respectively) in infants with Grade 3 or 4 IVH. The proportion of patients with PHH receiving a shunt has not changed over time (p = 0.813). CONCLUSIONS The increasing incidence of high-grade IVH-and PHH and shunt surgery in infants with high-grade IVH-over time is worrisome. This study identifies a number of associated factors, but further research to identify preventable and treatable causal factors is warranted. PMID:26030328

    Application of resting state functional connectivity magnetic resonance imaging (fcMRI) to the study of prematurely born infants enables assessment of the earliest forms of cerebral connectivity and characterization of its early development in the human brain. We obtained 90 longitudinal fcMRI data sets from a cohort of preterm infants aged from 26 weeks postmenstrual age (PMA) through term equivalent age at PMA-specific time points. Utilizing seed-based correlation analysis, we identified resting state networks involving varied cortical regions, the thalamus, and cerebellum. Identified networks demonstrated a regionally variable age-specific pattern of development, with more mature forms consisting of localized interhemispheric connections between homotopic counterparts. Anatomical distance was found to play a critical role in the rate of connection development. Prominent differences were noted between networks identified in term control versus premature infants at term equivalent, including in the thalamocortical connections critical for neurodevelopment. Putative precursors of the default mode network were detected in term control infants but were not identified in preterm infants, including those at term equivalent. Identified patterns of network maturation reflect the intricate relationship of structural and functional processes present throughout this important developmental period and are consistent with prior investigations of neurodevelopment in this population.

    Preterm birth (PTB) is a serious problem, with >450 000 neonates born prematurely in the United States every year. Beginning in 1980, the United States experienced a nearly 3-decade rise in the PTB rate, peaking in 2006 at 12.8%. PTB has declined for 7 consecutive years to 11.4% in 2013, but it still accounts for 1 in 9 neonates born every year. In addition to elevated neonatal and infant mortality among those born preterm, many who survive will have lifelong morbidities and disabilities. Because of the burden of morbidity, disability, and mortality for PTB, as well as its impact more broadly on society, including excess annual costs estimated to be at least $26.2 billion by a committee for the Institute of Medicine, the March of Dimes initiated the Prematurity Campaign in 2003. In 2008 the March of Dimes established a goal of reducing the US PTB rate to 9.6% by 2020. However, the United States ranks extremely poorly for PTB rates among Very High Human Development Index (VHHDI) countries, subjecting untold numbers of neonates to unnecessary morbidity and mortality. Therefore, the March of Dimes proposes an aspirational goal of 5.5% for the 2030 US PTB rate, which would put the United States in the top 4 (10%) of 39 VHHDI countries. This 5.5% PTB rate is being achieved in VHHDI countries and by women from diverse settings receiving optimal care. This goal can be reached and will ensure a better start in life for many more neonates in the next generation. PMID:25367536

    Allometry has been used to demonstrate a power–law scaling relationship in the brain of premature born infants. Forty-nine preterm infants underwent neonatal MRI scans and neurodevelopmental testing at age 2. Measures of cortical surface area and total cerebral volume demonstrated a power–law scaling relationship (α = 1.27). No associations were identified between these measures and investigated clinical variables. Term equivalent cortical surface area and total cerebral volume measures and scaling exponents were not related to outcome. These findings confirm a previously reported allometric scaling relationship in the preterm brain, and suggest that scaling is not a sensitive indicator of aberrant cortical maturation.

    OBJECTIVES: This study sought to determine the level of agreement between behavioral and multidimensional pain assessment scales in term newborn infants submitted to an acute nociceptive stimulus. METHODS: This cross-sectional study was performed on 400 healthy term newborns who received an intramuscular injection of vitamin K during the first 6 hours of life. Two behavioral pain scales (the Neonatal Facial Coding System and the Behavioral Indicators of Infant Pain) and one multidimensional tool (the Premature Infant Pain Profile) were applied by a single observer before the procedure, during cleansing, during injection and two minutes after injection. The Cochran Q, McNemar and kappa tests were used to compare the presence and degree of agreement between the three scales. The Hotelling T2 test was used to compare the groups of newborns for which the scales showed agreement or disagreement. A generalized linear regression was used to compare the results of the Neonatal Facial Coding System and the Behavioral Indicators of Infant Pain across the four study time points. RESULTS: The neonates studied had a gestational age of 39±1 weeks, a birth weight of 3169±316 g and and postnatal age of 67±45 minutes. During the stimulus procedure, 80% of the newborns exhibited pain behaviors according to the Neonatal Facial Coding System and the Behavioral Indicators of Infant Pain, and 70% experienced pain according to the Premature Infant Pain Profile (p<0.001). The frequencies of the detection of pain using the Behavioral Indicators of Infant Pain and the Neonatal Facial Coding System were similar. The characteristics of the neonates were not associated with the level of agreement between the scales. CONCLUSION: The Neonatal Facial Coding System and the Behavioral Indicators of Infant Pain behavioral scales are more sensitive for the identification of pain in healthy term newborn infants than the multidimensional Premature Infant Pain Profile scale.

    This case was one that would put many EMS personnel out of their comfort zones. The presentation of an unstable child is enough to have some providers put on their blinders and focus solely on the respiratory causes and overlook the cardiac. This child had been unstable most of the evening and by the time EMS was summoned was in severe need of treatment. The diagnosis of WPW in the field is almost impossible, especially when there is no history with the patient. Quick recognition of the infant's symptoms and analysis of the ECG allowed the paramedics to deliver the correct treatment for the arrhythmia while ensuring the respiratory issues weren't overlooked. The rapid treatment and transport were a significant part PMID:24984434

    The current process of educating and informing parents of the concerns and outcomes of premature infants is suboptimal, mostly because of modifiable factors. Proven methods to improve the transference of information are underused. In most institutions, the task to inform and educate parents is left to individual providers. Effective parent-clinician communication depends collectively on parents, clinicians, and the health care systems. Efforts must focus on improving communication and not on decreasing information provided to parents. If done successfully, we might find new and worthy allies in the trenches of the NICU.

    Neonatal brain hemorrhage (NBH) of prematurity is an unfortunate consequence of preterm birth. Complications result in shunt dependence and long-term structural changes such as post-hemorrhagic hydrocephalus, periventricular leukomalacia, gliosis, and neurological dysfunction. Several animal models are available to study this condition, and many basic mechanisms, etiological factors, and outcome consequences, are becoming understood. NBH is an important clinical condition, of which treatment may potentially circumvent shunt complication, and improve functional recovery (cerebral palsy, and cognitive impairments). This review highlights key pathophysiological findings of the neonatal vascular-neural network in the context of molecular mechanisms targeting the post-hemorrhagic hydrocephalus affecting this vulnerable infant population.

    Chronic lung disease of prematurity (CLD) remains a major cause of morbidity and mortality in preterm infants. Ureaplasma has received intermittent attention over the last two decades as a possible contributory factor. In addition, pulmonary inflammation is associated with the development of CLD. The macrolide azithromycin provides an attractive option to determine if it can decrease the development of CLD as it has both anti-inflammatory and anti-infective properties. In this article, the authors review the evidence for the role of Ureaplasma in the development of CLD and the obstacles faced in the development of a drug before it reaches clinical practice.

    We describe the pharmacokinetics of dolutegravir (DTG) in a premature neonate after maternal intensification of an antiretroviral (ARV) regimen by adding DTG. During the last 2 weeks of pregnancy, the ARV was tenofovir-emtricitabine, atazanavir-ritonavir, and DTG (50 mg once daily). From the interaction between atazanavir and DTG via CYP3A4 and UGT1A1 and placental efflux transporter inhibition and considering the infant's probable enzymatic immaturity, the DTG elimination half-life was estimated to be 4-fold longer in neonates than in adults.

    The purpose of the study was to compare a heel stick conducted during Kangaroo Care (skin-to-skin contact) with the mother to a heel stick in a warmer in reducing premature infant physiologic and behavioral pain responses. Twenty-four premature infants in a university-based neonatal intensive care unit were recruited and randomized to 2 sequences: sequence A group received 3 hours of Kangaroo Care (with a heel stick in Kangaroo Care) followed by 3 hours in a warmer (with a heel stick in the warmer). Sequence B group had warmer care and a heel stick (in the warmer) before Kangaroo Care and a heel stick (in Kangaroo Care). Heart rate, respiratory rate, oxygen saturation, crying time, and behavioral state were measured before, during, and after heel stick. Repeated measures ANOVA and Mann Whitney U statistics were performed. Heart rate and length of crying in response to pain were significantly reduced during Kangaroo Care and the Kangaroo Care heel stick as compared to when infants were in the warmer and had a heel stick in the warmer. Three infants did not cry at all during the Kangaroo Care heel stick; infants slept more during Kangaroo Care than in the warmer. Kangaroo Care positioning before and during heel stick is a simple and inexpensive analgesic intervention to ameliorate pain in stable premature infants. PMID:16082239

    There are no established screening criteria to help identify mothers of premature infants who are at risk for symptoms of emotional distress. The current study, using data obtained from recruitment and screening in preparation for a randomized controlled trial, aimed to identify potential risk factors associated with symptoms of depression, anxiety and posttraumatic stress in a sample of mothers with premature infants hospitalized in a neonatal intensive care unit. One hundred, thirty-five mothers of preterm infants born at 26-34 weeks of gestation completed three self-report measures: the Stanford Acute Stress Reaction Questionnaire, the Beck Depression Inventory (2nd ed.), and the Beck Anxiety Inventory to determine their eligibility for inclusion in a treatment intervention study based on clinical cut-off scores for each measure. Maternal sociodemographic measures, including race, ethnicity, age, maternal pregnancy history, and measures of infant medical severity were not helpful in differentiating mothers who screened positive on one or more of the measures from those who screened negative. Programs to screen parents of premature infants for the presence of symptoms of posttraumatic stress, anxiety, and depression will need to adopt universal screening rather than profiling of potential high risk parents based on their sociodemographic characteristics or measures of their infant's medical severity.

    The cradle warmer is based on technology in heated transparent materials developed by Sierracin Corporation, Sylmar, California he original application was in heated faceplates for the pressure suit heated faceplates worn by pilots of an Air Force/NASA reconnaissance and weather research plane. Later, Sierracin advanced the technology for other applications, among them the cockpit windows of the NASA X-15 supersonic research vehicle and the helmet faceplates of Apollo astronauts. Adapting the technology to hospital needs, Sierracin teamed with Cavitron Corporation, Anaheim, California, which produces the cradle warmer and two other systems employing Sierracin's electrically-heated transparencies. Working to combat the infant mortality rate, hospitals are continually upgrading delivery room and nursery care techniques. Many have special procedures and equipment to protect infants during the "period of apprehension," the critical six to 12 hours after delivery. One such item of equipment is an aerospace spinoff called the Infant Radiant Warmer, a "golden canopy" which provides uniform, controlled warmth to the infant's cradle. Warmth is vitally important to all newborns, particularly premature babies; they lose heat more rapidly than adults because they have greater surface area in comparison with body mass.

    This article is aimed to review and summarize the indications, outcomes and safety profiles regarding the use of intravitreal bevacizumab in patients with retinopathy of prematurity (ROP) as reported in previous studies with no intention to compare the efficacy between intravitreal bevacizumab and laser photocoagulation.Literature search was conducted in databases such as PubMed, Cochrane, Ovid, and Ophthalmology Advance using the terms "ROP," "antiangiogenic," "antivascular endothelial growth factor," "intravitreal bevacizumab," and "Avastin."Eight prospective studies of 278 eyes of ROP infants and 15 retrospective studies involving 385 eyes of ROP infants treated with intravitreal bevacizumab were found. Bevacizumab was used as monotherapy, adjunctive therapy, and/or combined therapy.The varied use of intravitreal bevacizumab in treating ROP and he limited number of landmark studies contribute to the difficulties in drawing a strong conclusion in this review. Intravitreal bevacizumab was more commonly injected in: (1) type 1 ROP zone I and/or posterior zone II; (2) aggressive posterior ROP with poor retinal visualization in which laser photocoagulation would be difficult to perform; and (3) stage 4 ROP before vitrectomy. All cases demonstrated regression of neovascular activity during a varied follow-up period (from 1 week to 1 month) after injection. However, recurrence may occur. Follow-up until 80 weeks of postmenstrual age is thus recommended. Acceleration of fibrous traction is the most common ocular adverse effect after injection, whereas the systemic adverse effect remains uncertain. Landmark studies of the efficacy of intravitreal bevacizumab injection in treating ROP are warranted. PMID:26107980

    Vestibulo-mediated cardiovascular control in hazardous situations is important. Our hypothesis is that the prerequisite for sudden infant death syndrome (SIDS) is impaired vestibulo-mediated cardiovascular control. Prematurity is a risk factor for SIDS, and postnatal intermittent hypoxia may contribute to this risk. We studied heart rate (HR) and blood pressure (BP) responses in 10 infants with bronchopulmonary dysplasia (BPD) who were born at 27 +/- 2.4 (23-30) wk of gestation. Twenty healthy term infants served as controls. Cardiovascular tests were performed under polysomnographic control during slow-wave sleep (SWS) at a corrected age of 12 +/- 3.5 (7-19) wk. Control infants showed biphasic HR and BP responses to side motion with an immediate increase followed by a modest decrease and return to baseline. Compared with the controls, half of the BPD infants had altered BP responses (p < 0.005) without an early increase, followed by a more prominent decrease in BP. BPD infants also presented with a greater variability in BP responses to head-up tilts than did the controls (p < 0.001). In conclusion, these findings suggest that some BPD infants have impaired vestibular sympathoreflex-mediated cardiovascular control. This dysfunction may become critical in life-threatening situations. PMID:17413872

    Definition in the living premature infant of the anatomical and temporal characteristics of development of critical brain structures is crucial for insight into the time of greatest vulnerability of such brain structures. We used three-dimensional magnetic resonance imaging (3D MRI) and image-processing algorithms to quantitate total brain volume and total volumes of cerebral gray matter (GM), unmyelinated white matter (WM), myelinated WM, and cerebrospinal fluid (CSF) in 78 premature and mature newborns (postconceptional age, 29-41 weeks). Total brain tissue volume was shown to increase linearly at a rate of 22 ml/wk. Total GM showed a linear increase in relative intracranial volume of approximately 1.4% or 15 ml in absolute volume per week. The pronounced increase in total GM reflected primarily a fourfold increase in cortical GM. Unmyelinated WM was found to be the most prominent brain tissue class in the preterm infant younger than 36 weeks of postconceptional age. Although minimal myelinated WM was present in the preterm infant at 29 weeks, between 35 and 41 weeks an abrupt fivefold increase in absolute volume of myelinated WM was documented. Extracerebral and intraventricular CSF was readily quantitated by this technique and found to change minimally. The application of 3D MRI and tissue segmentation to the study of human infant brain from 29 to 41 weeks of postconceptional age has provided new insights into cerebral cortical development and myelination and has for the first time provided means of quantitative assessment in vivo of early human brain development.

    Life course theory, a sociological framework, was used to analyze the phenomenon of becoming a mother, with longitudinal narrative data from 34 women who gave birth prematurely after a high-risk pregnancy, and whose infant became medically fragile. Women faced challenges of mistimed birth and mothering a technologically dependent infant. Before social ties were established, legal and biological ties required mothers to make critical decisions about their infants. Liminality characterized mothers' early involvement with their infants. The mothers worked to know, love, and establish deeper attachments to this baby. The infant's homecoming was a key turning point; it decreased liminality of early mothering, increased mothers' control of infants' care, and gave them time and place to know their infants more intimately.

  10. The Development and Neurobiology of Infant Attachment and Fear

    2013-01-01

    Survival of altricial infants depends on attachment to the caregiver – a process that requires infants to identify, learn, remember, and approach their attachment figure. Here we review the neurobiology of attachment in infant rats where learning about the caregiver is supported by a specialized attachment neural circuitry to promote the infant-caregiver relationship. Specifically, the attachment circuit relies on infants acquiring learned preferences to the maternal odor, and this behavior is supported by the hyper-functioning locus coeruleus and generous amounts of norepinephrine to produce experience-induced changes in the olfactory bulb and anterior piriform cortex. Infants also possess a reduced ability to acquire learned aversions or fear, and this behavior is facilitated through attenuated amygdala plasticity to block fear learning. Presumably, this attachment circuitry constrains the infant animal to express only learned preferences regardless of the quality of care received. As pups mature, and begin to travel in and out of the nest, the specialized attachment learning becomes contextually confined to when pups are with the mother. Thus, when outside the nest, these older pups show learning more typical of adult learning, presumably to prepare for independent life outside the nest. The quality of attachment can alter this circuitry, with early life stress prematurely terminating the pups’ access to the attachment system through premature functional activation of the amygdala. Overall, the attachment circuit appears to have a dual function: keeping pups close to the caregiver but also to shape pups’ behavior to match the environment and define long-term emotion and cognition.

    2016-01-01

    Clinical signs alone are unreliable in the diagnosis of patent ductus arteriosus (PDA) in preterm infants, and therefore echocardiography remains the mainstay of diagnosis of this common condition. Echocardiography also facilitates understanding of the hemodynamic effects of a PDA, and thus aids in management decisions. Several echocardiographic parameters, including duct size, maximum ductal velocity, left atrial: aorta ratio, mitral inflow E:A ratio, and isovolumic relaxation time, have been utilized in the assessment of PDA, but no single measurement can be used in isolation to inform clinical judgement. Therefore, it is important that echocardiographers on the neonatal unit have a comprehensive understanding of available methods and their limitations. Newer echocardiographic techniques, such as 3 Dimensional echocardiography, tissue Doppler imaging and strain imaging, are now providing insights into myocardial function in the adaptation of preterm infants to extra-uterine life, and into the effects of a PDA causing systemic-to-pulmonary artery shunting. Magnetic resonance imaging delivers excellent diagnostic information and accurate hemodynamic evaluation; however this modality is not easily accessible for most preterm infants, in comparison to echocardiography, which is readily available at the cotside in most neonatal units. Further developments in echocardiography may further refine the contribution it makes to individualized clinical decisionmaking in the management of premature infants with PDA. PMID:27197955

    2003-01-01

    It is only recently that newborns have been recognised to feel pain. To avoid the drawbacks of common analgesics, alternative analgesic methods (e.g. sucking and/or oral sugar) have been proposed. We showed that these methods are of little effect without the relaxing, distracting, comforting presence of a person at the cribside who talks to and massages the baby. This is a further demonstration that newborns, including premature babies, look for a reassuring presence when experiencing pain. This is surprising as premature babies are relatively unreactive, often completely isolated in an incubator and considered incapable of social behavior. To the attentive observer, however, they reveal an unsuspected emotional world. Not only do they feel pain, but they are also capable of suffering, distress, anxiety and fear. This needs to be considered in neonatal analgesic treatment, even for extremely premature children. It is mandatory for caregivers to be a reassuring presence during painful procedures: premature babies are exacting patients. They not only feel pain, they even suffer; they request not only drugs, but a human presence nearby. PMID:14700042
