    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

    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 four years and is now approximately 11.5%. Human viability, defined as gestational age at which the chance of survival is 50%, is currently approximately 23–24 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 EDC. 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 (ELBW) (< 1000 grams) remain at high risk for death and disability with 30–50% mortality and, in survivors, at least 20–50% risk of morbidity.

  6. Human milk for the premature infant.

    PubMed

    2013-02-01

    Premature infants are at risk for growth failure, developmental delays, necrotizing enterocolitis, and late-onset sepsis. Human milk from women delivering prematurely has more protein and higher levels of bioactive molecules. Human milk must be fortified for premature infants to achieve adequate growth. Mother's own milk improves growth and neurodevelopment, decreases the risk of necrotizing enterocolitis and late-onset sepsis, and should be the primary enteral diet for premature infants. Donor milk is a resource for premature infants whose mothers are unable to provide an adequate supply of milk. Challenges include the need for pasteurization, nutritional and biochemical deficiencies, and limited supply.

    Breast milk provides physiologic and neurodevelopmental protection for premature infants. Most hospitals are breast-milk friendly, but the number of premature infants breastfeeding successfully at discharge is relatively small. There are evidence-based techniques to improve the odds of premature infants breastfeeding at discharge and into the first year of life. Measures that help the infant make the transition to the breast include kangaroo care, nonnutritive sucking, avoidance of bottles, and consistent and supportive staff. A guide to management of the transition process is provided in this article.

    Synopsis Premature infants are a heterogeneous group with widely differing needs for nutrition and immune protection with risk of growth failure, developmental delays, necrotizing enterocolitis, and late-onset sepsis increasing with decreasing gestational age and birth weight. Human milk from women delivering prematurely has more protein and higher levels of many bioactive molecules compared to milk from women delivering at term. Human milk must be fortified for small premature infants to achieve adequate growth. Mother’s own milk improves growth and neurodevelopment and decreases the risk of necrotizing enterocolitis and late-onset sepsis and should therefore be the primary enteral diet of premature infants. Donor milk is a valuable resource for premature infants whose mothers are unable to provide an adequate supply of milk, but presents significant challenges including the need for pasteurization, nutritional and biochemical deficiencies and a limited supply.

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

  11. Human milk for the premature infant.

    Cunningham, M D; Desai, N S; Charlet, S S

    Closer study of premature infants has led to the establishment of human milk as the recommended nutritional standard for them. Infants fed with human milk are found to gain protection against necrotizing enterocolitis, and have fewer upper respiratory tract infections and systemic infections. Antibacterial components of human milk include leukocytes (macrophages, granulocytes, and T and B cell lymphocytes), the B cell secreted immunoglobulins, and complement factors. Lactoperoxidase and lactoferrin in breast milk are particularly active against group B beta hemolytic streptococcus and staphylococcus, respectively. Fresh human milk helps in the colonization of the infant's gut by Lactobacillus bifidus, a bacteria that suppresses other possibly pathogenic organisms. Nutritional values of human milk offer certain advantages and disadvantages over cow's milk. The quality of human milk protein is superior to that of cow's milk, and human milk's higher levels of cystine are especially required in the premature infant, where the liver is deficient in the enzyme required to convert methionine to cystine. Human milk is low in certain essential electrolytes and trace elements, such as sodium. It can also harbor drugs, pollutants, and harmful viruses that can be dangerous to the infant. Freezing of human milk for banking can destroy many of the immunological advantages of its use. Given that the advantages seem to outweigh the disadvantages, the authors favor the use of human milk for premature infants.

    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.

Details are reported on the biocide cutaneous properties of some chloro-derivates, as sodium hypochlorite and NaDCC, of ethyl and propyl alcohols, of chlorhexidine, of iodophors and also of triclosan and octenidine (even if these latter biocids are not normally available in Italy as cutaneous antiseptics).

  15. 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.

    Periventricular leukomalacia (PVL) in premature infants is a major cause of mortality and disability. However, while China is the largest developing country, there is an absence of data concerning PVL. This study was carried out in order to explore the incidence rate and analyze the high-risk factors of PVL in premature infants, and to suggest a working protocol for the prevention of PVL in newborns at risk. The cohort prospective study included 921 premature infants < 37 weeks' gestation from January 2004 to July 2007. The study group was comprised of 271 premature infants with an ultrasound diagnosis of PVL and the control group was comprised of 650 premature infants who were submitted to the same evaluation protocol but did not show any echographic signs of PVL. The results showed that the incidence rate of PVL was 29.4% in China. High-degree PVL accounted for < 12% and > 88% of PVL was low-degree. The incidence rate was much higher when premature infants were accompanied by the following complications: low gestational age, low birth weight, prolonged rupture of membranes, chorionitis, mechanical ventilation, periventricular-ventricular hemorrhage, hypocapnia, and hyperlactacidemia. Severe complications that occur in premature infants also significantly increase the incidence of PVL. Antenatal corticosteroids can significantly decrease the incidence rate of PVL. This investigation provided a theoretical reference for the prevention of premature PVL.

    Extremely premature infants face multiple acute and chronic life-threatening conditions. In addition, the treatments to ameliorate or cure these conditions often entail pain and discomfort. Integrating palliative care from the moment that extremely premature labor is diagnosed offers families and clinicians support through the process of defining goals of care and making decisions about life support. For both the extremely premature infant who dies soon after birth and the extremely premature infant who experiences multiple complications over weeks and months in the neonatal intensive care unit, palliative care can maintain a focus on infant comfort and family support. This article highlights the ways in which palliative care can be incorporated into intensive care for all critically ill infants.

    2014-01-01

    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.

    Introduction: Anemia in preterm infants is the pathophysiological process with greater and more rapid decline in hemoglobin compared to the physiological anemia in infants. There is a need for transfusions and administration of human recombinant erythropoietin. Aim: To determine the frequency of anemia in premature infants at the Pediatric Clinic, University Clinical Center Sarajevo, as well as parameter values in the blood count of premature infants and to explore a relationship between blood transfusions with the advent of intraventricular hemorrhage (determine treatment outcome in preterm infants). Patients and methods: Research is retrospective study and it included the period of six months in year 2014. Research included 100 patients, gestational age < 37 weeks (premature infants). Data were collected by examining the medical records of patients at the Pediatric Clinic, UCCS. Results: The first group of patients were premature infants of gestational age ≤ 32 weeks (62/100) and the second group were premature infants of gestational age 33-37 weeks (38/100). Among the patients, 5% were boys and 46% girls. There was significant difference in birth weight and APGAR score among the groups. In the first group, there were 27.42% of deaths, while in the second group, there were only 10.53% of deaths. There was a significant difference in the length of treatment. There was a statistically significant difference in the need for transfusion among the groups. 18 patients in the first group required a transfusion, while in the second group only 3 patients. Conclusions: Preterm infants of gestational age ≤ 32 weeks are likely candidates for blood transfusion during treatment. Preterm infants of gestational age ≤ 32 weeks have the risk of intracranial bleeding associated with the application of blood transfusion in the first week of life. PMID:28210010

    The purpose of this project was to improve the problem of decreased body temperature after ablution in premature infants, and increase the rate of recovery of body temperature. Before administration of this program, the rate of body temperature recovery was slow. The body temperatures of only 35% of premature infants' reached 36.5 degrees C at 30 minutes after bath, those of 43% did so at 60 minutes after bath, and those of 70 % did so at 120 minutes after bath. After a warmth maintenance nursing standard had been set, the bathing nursing standard corrected, standard interventions promoted and the system inspected, the percentage of body temperature recovery to 36.5 degrees C was raised from 35% to 74% at 30 minutes after bath and the body temperature became normal in all premature infants at 60 minutes after bath. This program not only solves the problem of low body temperature after ablution in premature infants, but also consolidates nursing staffs' knowledge and skills in maintaining body temperature in prematurity to promote the quality of premature care.

    2011-02-01

    Significant benefits to infant host defense, sensory-neural development, gastrointestinal maturation, and some aspects of nutritional status are observed when premature infants are fed their mothers' own milk. A reduction in infection-related morbidity in human milk-fed premature infants has been reported in nearly a dozen descriptive, and a few quasi-randomized, studies in the past 25 years. Human milk-fed infants also have decreased rates of rehospitalization for illness after discharge. Studies on neurodevelopmental outcomes have reported significantly positive effects for human milk intake in the neonatal period and long-term mental and motor development, intelligence quotient, and visual acuity through adolescence. Body composition in adolescence also is associated with human milk intake in the neonatal intensive care unit. Finally, human milk intake is less associated with the development of the metabolic syndrome than infant formula feeding.

    Purpose To conduct an integrative literature review to studies that focus on the transition of premature infants from neonatal intensive care unit (NICU) to home. Method A literature search was performed in Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed, and MEDLINE to identify studies consisting on the transition of premature infants from hospital to home life. Results The search yielded seven articles that emphasized the need for home visits, child and family assessment methods, methods of keeping contact with health care providers, educational and support groups, and described the nurse’s role in the transition program. The strategy to ease the transition differed in each article. Conclusion Home visits by a nurse were a key component by providing education, support, and nursing care. A program therefore should consist of providing parents of premature infants with home visits implemented by a nurse or staying in contact with a nurse (e.g., via video-conference). PMID:22763247

  8. Nutritional care of premature infants: microminerals.

    PubMed

    Domellöf, Magnus

    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.

    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

    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.

  13. Human milk and the premature infant.

    PubMed

    Bhatia, Jatinder

    Human milk is the preferred feeding for both term and preterm infants. While being considered optimal for term infants, human milk, even from mothers delivering preterm infants, is lacking in protein, energy, sodium, calcium, and phosphorus, resulting in poorer growth and nutrient deficiencies when compared to formulas designed for these high-risk infants. Further, the lack of growth is associated with long-term adverse consequences. Since human milk has unique properties in promoting gastrointestinal maturation and immunological benefits, it is prudent to implement strategies to fortify it appropriately to realize its benefits which include reduced rates of necrotizing enterocolitis, fewer episodes of sepsis and urinary tract infections, and improved visual and neurocognitive development. Donor human milk is being widely used when mothers' own milk is not available or is in short supply. While it retains some of the biological properties and clinical benefits of mothers' own milk, it requires additional care in fortification, especially if the donor milk is from a pool of term human milk. As nutritional strategies improve, the ultimate goal is to minimize extrauterine growth restriction and promote appropriate growth after regaining birth weight.

    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

    The aim of this pilot research was to investigate whether infants of mothers with panic disorder (PD) would be at higher risk for prematurity and low birth weight (corrected for gestational age) than controls. Medical records were reviewed for 25 mothers with PD and 33 mothers without a lifetime history of anxiety disorders or other major psychopathology as determined by diagnostic interview. Mothers also completed questionnaires concerning demographic information and life stresses. Compared to controls, infants with PD mothers were not significantly more likely to be born prematurely or earlier than controls but did show smaller birth weight corrected for gestational age, even after accounting for possible confounding influences. Additional research is needed to confirm these preliminary findings. Studying PD mothers during pregnancy could provide insight concerning mechanisms for the development of low birth weight and psychopathology.

    Newborn screening for severe combined immunodeficiency (SCID) is currently being performed in many states. It is important to address diagnostic challenges while outcomes are emerging from the first several years of screening. We present the case of a premature infant whose initial newborn screen was strongly positive for SCID. Subsequent lymphocyte subset analysis by flow cytometry was difficult to interpret due to the lack of age-matched reference values, a history of prenatal corticosteroid administration, and the possibility of maternal or posttransfusion engraftment. A repeat newborn screen for SCID ultimately revealed a normal result, confirming the initial newborn screen as a false positive. This case report reveals several of the diagnostic challenges unique to newborn SCID screening in premature infants and highlights the potential for states to address the feasibility of a standard protocol in this population.

    Premature infants have a shorter prenatal development period and are prone to many serious medical problems during neonatal period. This may impact the development of oral tissues, as manifested by enamel hypoplasia, palatal distortion, malocclusion, or delay in tooth eruption and maturation. Kangaroo mother care (KMC) is a standardized and protocol-based care system for premature infants, based on skin-to-skin contact between the infant and their mother. Kangaroo mother care has been demonstrated to greatly improve the nurturing of premature infants and comparatively reduce the risk factors of oral defects. We hypothesize that KMC also facilitates oral growth and development in premature infants.

    Acquired neonatal lung lesions including pneumatoceles, cystic bronchopulmonary dysplasia, and pulmonary interstitial emphysema can cause extrinsic mediastinal compression, which may impair pulmonary and cardiac function. Acquired lung lesions are typically managed medically. Here we report a case series of three extremely premature infants with acquired lung lesions. All three patients underwent aggressive medical management and ultimately required tube thoracostomies. These interventions were unsuccessful and emergency thoracotomies were performed in each case. Two infants with acquired pneumatoceles underwent unroofing of the cystic structure and primary repair of a bronchial defect. The third infant with pulmonary interstitial emphysema, arising from cystic bronchopulmonary dysplasia, required a middle lobectomy for severe and diffuse cystic disease. When medical management fails, tube thoracostomy can be attempted, leaving surgical intervention for refractory cases. Surgical options include oversewing a bronchial defect in the setting of a bronchopleural fistula or lung resection in cases of an isolated expanding lobe.

    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.

    Little is known about the relationship between maternal behavior and the stability of premature infants' physiologic responses during feeding. In a secondary data analysis, we examined relationships between quality of maternal behavior and cardiorespiratory physiology during feeding in 61 premature and 53 term infants at four times over the first year of life. Measures included heart rate (HR), respiratory rate (RR), and oxygen saturation; Child Feeding Skills Checklist; and Parent-Child Early Relational Assessment. Birthweight, gestational age, and neurodevelopmental risk were covariates. Quality of maternal behavior did not predict infants' physiologic response to feeding. However, birthweight was related to infant feeding physiology among all infants over the first year of life. Stress during fetal life, which may lead to impaired intrauterine growth and low birthweight, may have longitudinal effects on cardiorespiratory functioning of premature infants. Research is needed to further investigate the biological pathways by which maternal-infant interaction supports behavioral and physiologic feeding outcomes of premature infants.

    Although Bacillus cereus is a ubiquitous bacterium, the incidence of neonatal infections is very low with only a few cases of B. cereus infections in neonates reported in the literature. We report the case of a premature infant with multiple intestinal perforations and an abdominal B. cereus infection. The initial course was characterized by severe cardiovascular shock, anemia, thrombocytopenia and disseminated intravascular coagulation, leading to periventricular leukomalacia, alopecia capitis and toxic epidermal necrolysis. The possible role of B. cereus-associated enterotoxins for the clinical manifestations are discussed. Our case confirms previous reports of severe clinical symptoms in B. cereus infection in premature neonates. We speculate that the systemic complications of B. cereus infection are at least partly related to the effect of B. cereus-associated enterotoxins.

    Prolonged inhaled nitric oxide (iNO) from birth in preterm neonates with BPD improves endogenous surfactant function as well as lung growth, angiogenesis, and alveologenesis. As a result there is a reduction in the frequency of the "new" form of BPD in neonates under 28 weeks of gestation and birth weight under 1000 gr. Delivery of inhaled nitric oxide is a new method of prevention of chronic lung disease. According to a large number of randomized trials iNO in premature neonates reduces pulmonary morbidity and leads to a reduction of the mortality in this population of patients. This new therapy does not have serious side effects. We represent a clinical case of extremely premature newborn infant with BPD treated with iNO.

    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

    Retinopathy of prematurity (ROP), a vasoproliferative disorder exclusive to premature infants is an important cause of childhood blindness. The number of premature infants surviving with this condition is expected to increase globally. Animal models of oxygen-induced retinopathy studies have shown vascular endothelial growth factor (VEGF) to be a key player in the pathogenesis of ROP. This has led to increased use of VEGF antagonist as an alternative treatment for ROP. The purpose of this systematic review is to determine the association between VEGF and ROP in human newborn. The literature review identified 12 studies to date which fulfilled the search criteria. Investigators used cord blood, serum, plasma and tissue samples to investigate the association between ROP and VEGF. Studies that measured VEGF in cord blood found mixed results, with low VEGF (at birth) associated with ROP in one study and no difference noted in two others. Mixed results were also seen in studies determining VEGF in postnatal venous samples. Four studies showed no difference in VEGF level between premature infants with and without ROP, one study showed an increased VEGF level in premature infants with ROP and another study found serum VEGF to be low in premature infants with ROP. The most recent study demonstrated an initial increase in serum VEGF followed by a decline at the time of treatment. These contradictory results indicate that we are yet to fully understand the role of VEGF in human premature infants and question the rationale of treating ROP with anti-VEGF. Anti-VEGF therapy results in systemic effect on serum VEGF levels for up to 2 months and this could have an effect on neurodevelopmental outcome. The effect of this on other developing organs is currently unknown. More studies are required to determine the mechanistic relationships between systemic VEGF and ROP in premature infants.

    Little is known about the amino acid (AA) biosynthetic capacity and requirements of premature infants. This study assessed the synthesis of seven biochemically nonessential AA from a universal precursor, glucose, in stable, parenterally fed, premature neonates. Seven infants (six boys, one girl) were studied at a mean age of 6.3 +/- 0.6 (SEM) days; mean gestational age was 29.7 +/- 1.3 (SEM) weeks, and mean birth weight was 1,222.8 +/- 176.5 (SEM) grams. All infants were parenterally fed a mixture of 7.5% to 12.5% dextrose and 2.2% Trophamine, with or without lipid. Mean caloric intake was 93 +/- 8.4 (SEM) kcal/kg/d, and total AA intake was standardized at 2.86 g/kg/d AA, plus supplemental cysteine (30 mg/g AA/d). Each infant received a 4-hour continuous, unprimed intravenous infusion of a stable isotope tracer of D(-)[U13C] glucose (200 mg/kg). Blood samples were obtained before and at the end of the infusion. Conversion of the glucose tracer into seven biochemically nonessential AA (cysteine [Cys], proline [Pro], aspartate [Asp], serine [Ser], glutamate [Glu], alanine [Ala], and glycine [Gly]) was assessed by measuring their isotopic enrichment in plasma, using gas chromatography/mass spectrometry (GC/MS), and expressed as mole percent excess (MPE) (mean +/- SEM). The isotopic enrichment of plasma glucose was also measured using GC/MS. Free plasma AA concentrations (mean +/- SD) were measured using an automated amino acid analyzer. Mean MPE for M + 1, M + 2 and M + 3 Cys, and for M + 1 and M + 3 Pro were not significantly different from 0; M + 2 Pro barely achieved statistical significance (P = .048).(ABSTRACT TRUNCATED AT 250 WORDS)

    Objectives To describe adverse events (AEs) and noteworthy clinical or ocular findings associated with retinopathy of prematurity (ROP) evaluation procedures. Study design Descriptive analysis of pre-defined AEs and noteworthy findings reported in a prospective observational cohort study of infants <1251 g birth weight (BW) who had ROP study visits consisting of both binocular indirect ophthalmoscopy (BIO) and digital retinal imaging. We compared infant characteristics during ROP visits with and without AEs. We compared respiratory support, nutrition, and number of apnea, bradycardia, or hypoxia events 12 hours before and after ROP visits. Results 1,257 infants, mean BW 802 g, had 4,263 BIO and 4,048 imaging sessions (total 8,311 procedures). No serious AEs were related to ROP visits. Sixty-five AEs were reported among 61 infants for an AE rate of 4.9% infants (61/1257) or 0.8% total procedures (65/8311 BIO + imaging). Most AEs were due to apnea, bradycardia, and/or hypoxia (68%), tachycardia (16%), or emesis (8%). At ROP visit, infants with AEs, compared with those without, were more likely to be on mechanical ventilation (26% versus 12%, p=0.04) even after adjustment for weight and PMA. Noteworthy clinical findings were reported during 8% BIO and 15% imaging exams. Respiratory and nutrition support were not significantly different before and after ROP evaluations. Conclusions Retinal imaging by non-physicians combined with BIO was safe. Noteworthy clinical findings occurred during both procedures. Ventilator support was a risk factor for AEs. Monitoring rates of AEs and noteworthy findings are important to the safe implementation of ROP imaging protocols. Trial registration Clinicaltrials.gov: NCT01264276 PMID:26299381

    Infants of <30 wk gestation often require respiratory support for several weeks and may develop bronchopulmonary dysplasia (BPD), which is associated with long-term pulmonary disability or death in severe cases. To examine the status of surfactant in infants at high risk for BPD, this prospective study analyzed 247 tracheal aspirate samples from 68 infants of 23-30 wk gestation who remained intubated for 7-84 d. Seventy-five percent of the infants had one or more surfactant samples with abnormal function (minimum surface tension 5.1-21.7 mN/m by pulsating bubble surfactometer), which were temporally associated with episodes of infection (p = 0.01) and respiratory deterioration (p = 0.005). Comparing normal and abnormal surfactant samples, there were no differences in amount of surfactant phospholipid, normalized to total protein that was recovered from tracheal aspirate, or in relative content of phosphatidylcholine and phosphatidylglycerol. Contents of surfactant proteins (SP) A, B, and C, measured in the surfactant pellet by immunoassay, were reduced by 50%, 80%, and 72%, respectively, in samples with abnormal surface tension (p < or = 0.001). On multivariable analysis of all samples, SP-B content (r = -0.58, p < 0.0001) and SP-C content (r = -0.32, p < 0.001) were correlated with surfactant function. We conclude that most premature infants requiring continued respiratory support after 7 d of age experience transient episodes of dysfunctional surfactant that are associated with a deficiency of SP-B and SP-C.

    A female infant born prematurely at 23 weeks' gestational age developed bilateral hereditary cataracts at post-menstrual age 33 weeks, which precluded retinopathy of prematurity screening. The infant underwent right cataract extraction 1 week later, and retinopathy of prematurity was monitored by examining the right eye. In the seventeenth week of life (post-menstrual age 40 weeks), the cataract was removed from the left eye. Visual outcome at 19 months of age was good in both eyes. Very early cataract extraction may be necessary in premature infants to allow ROP evaluations.

    Our aim was to determine whether rhinovirus (RV) lower respiratory tract infections (LRTIs) in prematurely born infants increase health-related cost of care during infancy. 153 infants born at <36 weeks of gestation were prospectively followed to 1 year. Cost of care was calculated from the National Health Service reference costing scheme and healthcare utilisation determined by examining hospital/general practitioner records. 20 infants developed RV LRTIs (RV group), 17 respiratory syncytial virus (RSV) LRTIs (RSV group), 12 both RV and RSV LRTIs (RV/RSV group) and 74 had no LRTI (no LRTI group). Compared with the no LRTI group, the RV/RSV LRTI group had the greatest increase in adjusted mean cost (difference GBP 5769), followed by the RV LRTI group (difference GBP 278) and, finally, the RSV LRTI group (difference GBP 172) (p=0.045). The RV group had more outpatient (p<0.05) and respiratory-related general practitioner (p<0.05) attendances, more wheezed at follow-up (p<0.001) than the no LRTI group and more had respiratory-related outpatient attendances than the RSV LRTI group (p<0.05). We conclude that RV LRTIs were associated with increased health-related cost of care during infancy; our results suggest that the RV group compared with the RSV group suffered greater chronic respiratory morbidity.

    A series of premature infants was studied for the presence of bacterial infection. On the basis of clinical evidence and bacteriological studies, they were divided into three groups in which sepsis was considered to be proven, possible, or unlikely. Band neutrophil counts were elevated most frequently in the "sepsis-proven" group and the elevation occurred usually within 24 hours of onset of signs of disease. Qualitative changes in neutrophils (Döhle bodies, toxic granulation, and vacuolization) were more frequent in the sepsis-proven group and, together with the band count, provided valuable techniques for the diagnosis of bacterial infections. Thrombocytopenia occurred frequently in the sepsis-proven group and seemed to result from increased utilization or destruction of platelets rather than failure of production. In such cases, evidence of intravascular coagulation was minimal and it was concluded that thrombocytopenia had resulted from a direct effect of the bacteria or its products on platelets and/or endothelium.

    OBJECTIVE: To recommend appropriate intake of nutrients, food sources and feeding practices for premature infants. OPTIONS: Unfortified milk from the premature infant's own mother, fortified milk from the premature infant's own mother, formula designed for preterm infants and parenteral nutrition. OUTCOMES: From birth to 7 days, the minimum achievable goal is the provision of sufficient nutrients to prevent deficiencies and catabolism of nutrient substrate in premature infants; from 7 days to discharge from the neonatal intensive care unit, growth and nutrient retention at a rate similar to that which would have been achieved had the infant remained in utero; and for 1 year following discharge, nutrient intake to achieve catch-up growth. EVIDENCE: Few randomized clinical trials of feeding infants specific nutrients or of feeding choices have been conducted. On the basis of a MEDLINE search of the literature, committee members prepared reviews of the available information on each nutrient and feeding choice. The reviews were critically appraised by the committee. Recommendations were based on the consensus of the committee. VALUES: Whenever possible, the evidence was weighed in favour of randomized controlled trials. If such trials were unavailable, cohort studies were considered. If trials of either kind were unavailable, published data were reviewed and recommendations were based on consensus opinion. BENEFITS, HARMS AND COSTS: The advantages of feeding premature infants unfortified milk from their own mothers are psychologic benefits for the mother as well as anti-infective benefits and possibly improved intellectual development for the infant. However, unfortified milk from the infant's own mother is inadequate as a sole source of nutrients. The use of fortified milk from the mother results in faster growth as well as having the other benefits of mother's milk. When formulas designed for premature infants are given in adequate volumes, they provide an intake of

    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.

    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

    This study aimed to describe nurses' expectations of using music for premature infants in the neonatal intensive care unit (NICU) and to find out about the related background factors. The subjects consisted of 210 Finnish nurses who were recruited from the country's five university hospitals providing premature infant care in NICU. The data were collected by validated questionnaire, and the response rate was 82%. Most nurses preferred recorded music to live music in the NICU. They expected that music would have positive effects on premature infants, parents, and staff. Few demographic and many background factors of the respondents' music-related experiences correlated significantly with the expectations concerning their preference. In conclusion, the nurses' expectations were positive regarding the use of music in the NICU, which supports evidence regarding the efficacy of music therapy for premature infants.

    Achondroplasia is a difficult prenatal diagnosis to make before the late second and third trimester. We describe two cases where an infant was born prematurely with no overt signs of achondroplasia. Despite multiple chest and abdominal radiographs during the neonatal course, the diagnosis was not made until term equivalent age was reached. We retrospectively reviewed these two cases to highlight the elusive findings of achondroplasia in the premature infant. PMID:28210519

    Oxidation of orally administered [13C]glucose and [13C]lactose and fecal recovery of malabsorbed substrates were determined in two groups of premature infants. Eighteen studies were performed with six infants at Johns Hopkins Hospital (JHH); 24 studies were performed with nine infants at Columbus Children's Hospital (CCH). The two groups differed in that JHH infants had shorter gestations but were older when studied. Fecal 13C loss after [13C]glucose administration did not differ between the two groups. Compared with glucose, the metabolism of lactose appeared to involve more malabsorption and colonic fermentation in JHH infants than in CCH infants and resulted in higher fecal losses of substrate carbon. Maturation appeared to involve increased proximal intestinal absorption and greater retention of absorbed carbohydrate. Simultaneous absorption of substrate from the small and large intestine may limit the usefulness of breath tests for 13C 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

    The purpose of this study was to evaluate the effect of white noise as a distraction method in relieving procedural pain caused by vaccination for premature infants. This experimental study was performed at a neonatal intensive care unit (NICU) of a university hospital in Turkey between July and September 2013. The study population was composed of 75 premature infants (35 in the study group and 40 in the control group) who met the inclusion criteria. Premature infants in the study group were exposed to white noise using MP3 players placed at the head of the infants' open crib for 1 minute before vaccination. The white noise continued until 1 minute after vaccination. Premature infants in the control group were not exposed to white noise. The Premature Infant Information Form, Intervention Follow-up Form, and Premature Infant Pain Profile (PIPP) were used to collect study data. Descriptive statistics, chi-square test, and independent sample t-tests were used to evaluate the data. The pain level of the control group (PIPP = 14.35 ± 2.59) was significantly higher than the pain level of the study group (PIPP = 8.14 ± 3.14) (p < .05). The authors found that 67.6% of the infants in the study group had moderate pain during vaccination and only 2.9% had severe pain. Most of the infants in the control group (82.5%) had severe pain, whereas 17.5% had moderate pain (p < .05). White noise was found to be effective for this sample; however, there is a dire need for extensive research on white noise and its use with this vulnerable population.

    This meta-analysis on music research with premature infants in neonatal intensive care units (NICU) showed an overall large, significant, consistent effect size of almost a standard deviation (d =.83) (Cohen, 1998). Effects were not mediated by infants' gestational age at the time of study, birthweight, or type of music delivery nor by physiologic, behavioral, or developmental measures of benefit. The homogeneity of findings suggests that music has statistically significant and clinically important benefits for premature infants in the NICU. The unique acoustic properties that differentiate music from all other sounds are discussed and clinical implications for research-based music therapy procedures cited.

    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.

    1995-04-01

    The responder cell frequency (RCF) of premature (< 1900 g birth weight) infants' blood lymphocytes, which proliferate in cultures stimulated by staphylococcal enterotoxin B, falls from 1:3400 to about 1:8000 during the first 2 wk of life. Term infants, in contrast, show no fall in RCF. The reduced RCF in the premature infants affected cells that make interferon-gamma more than cells making IL-4. The reduced RCF was accompanied by a fall in the fraction of V beta 3+ T cells that entered cell cycle in stimulated cultures. The RCF of premature infants' T cells was increased in cultures supplemented with irradiated monocytes from adults. Addition of IL-4 (but not IL-2, IL-6, or indomethacin) increased the RCF and fraction of cells entering cell cycle of the premature infants. The data suggest that postnatal environmental factors limit the ability of premature infants' monocytes to support a T-cell response to staphylococcal enterotoxin B in vitro and that this limitation is overcome by adding IL-4.

    Background: This study aimed to understand the confront strategies of parents of premature infants hospitalized in NICU. Methods: This study was performed using qualitative content analysis approach. Twelve participants including nine parents whose infants were hospitalized in NICU, two nurses and one physician, all selected by purposive sampling method were interviewed by a female expert occupational therapist. Data were gathered by semistructured interviews. Data were analyzed by inductive content analysis approach. Results: One category, six subcategories and twenty one themes emerged from data analysis expressed confront strategies of parents of premature infants admitted in NICU. These categories were: taking assurance, stop thinking to bad things, diverting mind, taking supports, emotional expression, complaining from staff. Conclusion: Premature infant's parents announced that they do not receive adequate formal support to manage their feelings and needs. So, they seek for other informal resources of support and apply some special strategies including self-support. PMID:25664283

  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.

    Objective To determine the impact of two probiotic bifidobacteria on the fecal microbiota of premature infants fed either human milk or formula. Study design In the first of two phase 1 clinical trials, twelve premature infants receiving formula feedings were randomly assigned to receive either Bifidobacterium longum ssp infantis or Bifidobacterium animalis ssp lactis in increasing doses over a five week period. In the second, nine premature infants receiving their mother’s milk received each of the two bifidobacteria for two weeks separated by a one week wash out period. Serial stool specimens from each infant were analyzed by terminal restriction fragment length polymorphism and quantitative polymerase chain reaction for bacterial composition. Results Among the formula-fed infants, there was a greater increase in fecal bifidobacteria among infants receiving B. infantis than those receiving B. lactis. This difference was most marked at a dose of 1.4 × 109 cfu twice daily (p < 0.05). Bacterial diversity improved over dose/time in those infants receiving B. infantis. Among the human milk-fed infants, greater increases in fecal bifidobacteria and decreases in γ-Proteobacteria followed administration of B. infantis than B. lactis. The B. longum group (which includes B. infantis but not B. lactis) was the dominant bifidobacteria among the human milk-fed infants, regardless of the probiotic administered. Conclusions B. infantis was more effective at colonizing the fecal microbiota than B. lactis in both formula-fed and human milk-fed premature infants. The combination of human milk plus B. infantis resulted in the highest fecal levels of bifidobacteria. PMID:23993139

    Objectives In premature infants with suspected intra-abdominal infection, biomarkers for treatment response to antimicrobial therapy are lacking. Intestinal fatty acid-binding protein (I-FABP) is specific to the enterocyte and is released in response to intestinal mucosal injury. I-FABP has not been evaluated as a surrogate marker of disease response to antimicrobial therapy. We examined the relationship between metronidazole exposure and urinary I-FABP concentrations in premature infants with suspected intra-abdominal infection. Study design We conducted an intravenous metronidazole pharmacokinetic study, collecting ≤3 urine samples per infant for I-FABP concentration measurements. We analyzed the relationship between I-FABP concentrations and measures of metronidazole exposure and pharmacokinetics, maturational factors, and other covariates. Results Twenty-six samples from 19 premature infants were obtained during metronidazole treatment. When analyzed without regard to presence of necrotic gastrointestinal disease, there were no significant associations between predictor variables and I-FABP concentrations. However, when the sample was limited to premature infants with necrotic gastrointestinal disease, an association was found between average predicted metronidazole concentration and I-FABP concentration (p=0.006). Conclusion While a predictive association between urinary I-FABP and metronidazole systemic exposure was not observed, the data suggest the potential of this endogenous biomarker to serve as a pharmacodynamic surrogate for antimicrobial treatment of serious abdominal infections in neonates and infants.

    (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

    The present study was focusing on the very few contacts with the mother's voice that NICU infants have in the womb as well as after birth, we examined whether they can discriminate between their mothers' utterances and those of female nurses in terms of the emotional bonding that is facilitated by prosodic utterances. Twenty-six premature infants were included in this study, and their cerebral blood flows were measured by near-infrared spectroscopy. They were exposed to auditory stimuli in the form of utterances made by their mothers and female nurses. A two (stimulus: mother and nurse) x two (recording site: right frontal area and left frontal area) analysis of variance (ANOVA) for these relative oxy-Hb values was conducted. The ANOVA showed a significant interaction between stimulus and recording site. The mother's and the nurse's voices were activated in the same way in the left frontal area, but showed different reactions in the right frontal area. We presume that the nurse's voice might become associated with pain and stress for premature infants. Our results showed that the premature infants reacted differently to the different voice stimuli. Therefore, we presume that both mothers' and nurses' voices represent positive stimuli for premature infants because both activate the frontal brain. Accordingly, we cannot explain our results only in terms of the state-dependent marker for infantile individual differences, but must also address the stressful trigger of nurses' voices for NICU infants.

    Abstract Objective This study investigated clinicians' perspectives during a quality improvement project to promote breastmilk feedings in premature infants. Study Design From 2009 to 2010, 11 hospitals in the California Perinatal Quality Care Collaborative participated in a project to promote breastmilk feedings in premature infants. Audio recordings of monthly meetings held to encourage sharing of ideas were analyzed using qualitative methods to identify common themes related to barriers and solutions to breastmilk feeding promotion. Results Two broad categories were noted: communication and team composition. Communication subthemes included (1) communication among hospital staff, including consistent documentation, (2) communication with family, and (3) communication between transfer hospitals. Team composition subthemes included (4) importance of physician buy-in and (5) integrated teams designed to empower leaders. Conclusions Optimizing communication among health professionals and parents and improving team composition may be key components of facilitating breastmilk feeding promotion in premature infants.

    The rate of premature births has increased in the past 2 decades. Ten percent of premature birth survivors develop motor impairment, but almost half exhibit later sensorial, cognitive, and emotional disabilities attributed to white matter injury and decreased volume of neuronal structures. The aim of this study was to test the hypothesis that premature and full-term infants differ in their development of emotional face processing. A comparative longitudinal study was conducted in premature and full-term infants at 4 and 8 months of age. The absolute power of the electroencephalogram was analyzed in both groups during 5 conditions of an emotional face processing task: positive, negative, neutral faces, non-face, and rest. Differences between the conditions of the task at 4 months were limited to rest versus non-rest comparisons in both groups. Eight-month-old term infants had increases ( P ≤ .05) in absolute power in the left occipital region at the frequency of 10.1 Hz and in the right occipital region at 3.5, 12.8, and 16.0 Hz when shown a positive face in comparison with a neutral face. They also showed increases in absolute power in the left occipital region at 1.9 Hz and in the right occipital region at 2.3 and 3.5 Hz with positive compared to non-face stimuli. In contrast, positive, negative, and neutral faces elicited the same responses in premature infants. In conclusion, our study provides electrophysiological evidence that emotional face processing develops differently in premature than in full-term infants, suggesting that premature birth alters mechanisms of brain development, such as the myelination process, and consequently affects complex cognitive functions.

    Factors affecting bone turnover in premature infants are not entirely clear but certainly are different from those influencing bones of adults and children. To identify fetal and maternal factors that might influence bone turnover, we prospectively studied 50 infants (30 preterm and 20 full-term) born at Ain Shams University Obstetric Hospital in Cairo, Egypt. Maternal parity and medical history and infant's weight, gestational age, gender and anthropometrical measurements were recorded. Cord blood samples were collected and serum type I collagen C-terminal propeptide (PICP) was assessed as a marker for fetal bone formation. First morning urine samples were collected and pyridinoline cross-links of collagen (Pyd) were measured as an index for bone resorption. Serum PICP was higher in premature infants when compared with full-term infants (73.30 +/- 15.1 versus 64.3 +/- 14.7, p = 0.022) and was higher in male premature infants when compared with females (81.64 +/- 9.06 versus 66.0 +/- 15.7, p = 0.018). In a multiple regression model using PICP as the dependent variable and controlling for different infant and maternal conditions, PICP significantly correlated with infant gender (r = 8.26 +/- 4.1, p = 0.05) maternal parity (r = -2.106 +/- 0.99, p = 0.041) and diabetes (r = 22.488 +/- 8.73, p = 0.041). Urine Pyd tended to increase in premature infants (612 +/- 308 versus 434 +/- 146, p = 0.057) and correlated significantly with gestational age (r = -63.93 +/- 19.55, p = 0.002). Therefore, bone formation (PICP) is influenced by fetal age and gender, as well as maternal parity and diabetes. Bone resorption (Pyd) is mostly dependent on gestational age only. Further in-depth studies are needed to enrich management of this vulnerable population.

    OBJECTIVE Intraventricular hemorrhage (IVH) is a complication of prematurity often associated with ventricular dilation, which may resolve over time or progress to posthemorrhagic hydrocephalus (PHH). This study investigated anatomical factors that could predispose infants with IVH to PHH. METHODS The authors analyzed a cohort of premature infants diagnosed with Grade III or IV IVH between 2004 and 2014. Using existing ultrasound and MR images, the CSF obstruction pattern, skull shape, and brain/skull ratios were determined, comparing children with PHH to those with resolved ventricular dilation (RVD), and comparing both groups to a set of healthy controls. RESULTS Among 110 premature infants with Grade III or IV IVH, 65 (59%) developed PHH. Infants with PHH had more severe ventricular dilation compared with those with RVD, although ranges overlapped. Intraventricular CSF obstruction was observed in 36 (86%) of 42 infants with PHH and 0 (0%) of 18 with RVD (p < 0.001). The distribution of skull shapes in infants with PHH was similar to those with RVD, although markedly different from controls. No significant differences in supratentorial brain/skull ratio were observed; however, the mean infratentorial brain/skull ratio of infants with PHH was 5% greater (more crowded) than controls (p = 0.006), whereas the mean infratentorial brain/skull ratio of infants with RVD was 8% smaller (less crowded) than controls (p = 0.004). CONCLUSIONS Among premature infants with IVH, intraventricular obstruction and infratentorial crowding are strongly associated with PHH, further underscoring the need for brain MRI in surgical planning. Prospective studies are required to determine which factors are cause and which are consequence, and which can be used to predict the need for surgical intervention.

    2009-01-01

    Over the decades, medical staff have developed strategies to manage crying episodes of the critically ill and convalescing premature infant. These episodes of crying occur frequently after infants are removed from ventilation, but before they are able to receive nutrition orally. Not only are these episodes stressful to infants and upsetting to parents, but they are also stressful and time consuming for the staff that take care of these patients. Although the literature supports the benefits of music therapy in regard to physiological and certain behavioral measures with premature infants, no research exists that explores the use of music therapy with inconsolability related to the "nothing by mouth" status. This study explored the effects of music therapy on the crying behaviors of critically ill infants classified as inconsolable. Twenty-four premature infants with gestational age 32-40 weeks received a developmentally appropriate music listening intervention, alternating with days on which no intervention was provided. The results revealed a significant reduction in the frequency and duration of episodes of inconsolable crying as a result of the music intervention, as well as improved physiological measures including heart rate, respiration rate, oxygen saturation, and mean arterial pressure. Findings suggest the viability of using recorded music in the absence of a music therapist or the maternal voice to console infants when standard nursing interventions are not effective.

    Length and thickness of 152 corpus callosa were measured in neonates within 24 hours of birth. Using ultrasonic diagnostic equipment with a neonatal brain-specific probe, corpus callosum length and thickness of the genu, body, and splenium were measured on the standard mid-sagittal plane, and the anteroposterior diameter of the genu was measured in the coronal plane. Results showed that corpus callosum length as well as thickness of the genu and splenium increased with tional age and birth weight, while other measures did not. These three factors on the standard mid-sagittal plane are therefore likely to be suitable for real-time evaluation of corpus callosum velopment in premature infants using cranial ultrasound. Further analysis revealed that thickness of the body and splenium and the anteroposterior diameter of the genu were greater in male infants than in female infants, suggesting that there are sex differences in corpus callosum size during the neonatal period. A second set of measurements were taken from 40 premature infants whose gestational age was 34 weeks or less. Corpus callosum measurements were corrected to a gestational age of 40 weeks, and infants were grouped for analysis depending on the outcome of a neonatal behavioral neurological assessment. Compared with infants with a normal neurological assessment, corpus callosum length and genu and splenium thicknesses were less in those with abnormalities, indicating that corpus callosum growth in premature infants is associated with neurobehavioral development during the early extrauterine stage.

    Late-onset sepsis in premature infants is a major cause of morbidity, mortality, and increased medical costs. Risk factors include low birth weight, low gestational age, previous antimicrobial exposure, poor hand hygiene, and central venous catheters. Methods studied to prevent late-onset sepsis include early feedings, immune globulin administration, prophylactic antimicrobial administration, and improved hand hygiene. In this review, we will outline the risk factors for development of late-onset sepsis and evidence supporting methods for prevention of late-onset sepsis in premature infants. PMID:20116186

    After births, premature infants need a high level of medical treatments for their survivals in the neonatal intensive care unit (NICU). This separation deprives mothers of the chance to initiate an attachment process. Kangaroo care (KC) can be one of the ways to reunite mothers and their infants in the NICU and improve health outcomes. This study was conducted to investigate the effects of KC on both premature infants and their mothers. Ten sessions of 60-min KC for 3 weeks were practiced at a level III NICU at E university hospital. Infants' body weight, height and head circumference (HC), maternal attachment and depression were measured. As a result, premature infants in KC showed higher in their height and bigger in their HC than infants in control. Maternal attachment scores were higher among the KC mothers. The results supported the beneficial effects of KC on Korean premature infants and their mothers.

    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.

    The purpose of this study was to investigate how premature infants' oxygen saturation changed in response to music therapy while they were receiving endotracheal suctioning. A convenience sample of 30 premature infants was selected from three neonatal intensive care units. A one-group repeated measures design was adopted for this study. The oxygen saturation of all subjects was first measured while they were receiving endotracheal suctioning during a four-hour control period with regular care. Then, four hours after the control period was completed, an experimental period began in which the music " Transitions " was played. One minute before suctioning, the level of oxygen saturation was measured to provide the baseline data. During a period of 30 minutes after suctioning, the oxygen saturation was recorded every minute to analyze the clinical effects of music therapy. The results showed that premature infants receiving music therapy with endotracheal suctioning had a significantly higher SPO(2); than that when not receiving music therapy (p <.01), and the level of oxygen saturation returned to the baseline level faster than when they did not receive music therapy (p <.01). Accordingly, it is hoped that giving appropriate music therapy as developmental care to premature infants when performing any nursing intervention may enhance not only the quality of nursing care but also quality of the infant's life.

    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.

    We tested healthy preterm (born near 28 +/- 2 weeks of gestational age) and full-term infants at various different ages. We compared the two populations on the development of a language acquisition landmark, namely, the ability to distinguish the native language from a rhythmically similar one. This ability is attained 4 months after birth in healthy full-term infants. We measured the induced gamma-band power associated with passive listening to (i) the infants' native language (Spanish), (ii) a rhythmically close language (Italian), and (iii) a rhythmically distant language (Japanese) as a marker of gains in language discrimination. Preterm and full-term infants were matched for neural maturation and duration of exposure to broadcast speech. We found that both full-term and preterm infants only display a response to native speech near 6 months after their term age. Neural maturation seems to constrain advances in speech discrimination at early stages of language acquisition.

    A randomized controlled study was done to determine whether the addition of heparin (1 U/mL) to peripheral intravenous alimentation solutions would affect the incidence of phlebitis and duration of patency of intravenous catheters in premature infants. Twenty-two-gauge Teflon catheters were uniformly used. One hundred five catheters infused with heparin were placed in 13 infants, and 122 catheters were placed in the control group of 13 infants. The time, nature, and incidence of complications were noted for each infusion site. Infusion of heparin was found to double the duration of patency of intravenous catheters and to reduce significantly the incidence of phlebitis. No complications related to the administration of heparin were noted. Heparinization of intravenous alimentation solutions should therefore be considered in premature infants as a means of reducing the work load and incidence of complications associated with peripheral lines.

    In the past decades, multiple studies have been interested in developmental patterns of the visual system in healthy infants. During the first year of life, differential maturational changes have been observed between the Magnocellular (P) and the Parvocellular (P) visual pathways. However, few studies investigated P and M system development in infants born prematurely. The aim of the present study was to characterize P and M system maturational differences between healthy preterm and fullterm infants through a critical period of visual maturation: the first year of life. Using a cross-sectional design, high-density electroencephalogram (EEG) was recorded in 31 healthy preterms and 41 fullterm infants of 3, 6, or 12 months (corrected age for premature babies). Three visual stimulations varying in contrast and spatial frequency were presented to stimulate preferentially the M pathway, the P pathway, or both systems simultaneously during EEG recordings. Results from early visual evoked potentials in response to the stimulation that activates simultaneously both systems revealed longer N1 latencies and smaller P1 amplitudes in preterm infants compared to fullterms. Moreover, preterms showed longer N1 and P1 latencies in response to stimuli assessing the M pathway at 3 months. No differences between preterms and fullterms were found when using the preferential P system stimulation. In order to identify the cerebral generator of each visual response, distributed source analyses were computed in 12-month-old infants using LORETA. Source analysis demonstrated an activation of the parietal dorsal region in fullterm infants, in response to the preferential M pathway, which was not seen in the preterms. Overall, these findings suggest that the Magnocellular pathway development is affected in premature infants. Although our VEP results suggest that premature children overcome, at least partially, the visual developmental delay with time, source analyses reveal abnormal brain

    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. Histopathologic evidence of chronic chorioamnionitis and positive staining with immunohistochemistry for HSV in the placenta and umbilical cord established the diagnosis. The clinical presentation was also of interest in that the infant was initially healthy appearing.

    2005-01-01

    Within the past 5 years there has been an increase of premature infants surviving in the neonatal intensive care unit as well as an increasing cost for each day the infant is kept there. It is important for the premature infant to acquire the feeding skills necessary for weight gain, which lead to discharge from the hospital, and recent advancements have indicated the effectiveness in using contingent music to teach sucking skills to premature infants. The purpose of the first analysis in this study was to determine the effects of Pacifier Activated Lullaby (PAL) trials on weight gain of premature infants. During a 2-year time period, 62 infants from a sample of 188 met criteria for analysis. A one-way analysis of variance showed no significance in daily weight gain for the number of PAL trials completed. The mean weight gains for infants with 1 PAL trial = 13.85 grams, 2 trials = 26.67, 3 trials = 29.64, and 4 or more = 22.89. The Pearson product-moment correlation between the mean percent of music earned via nonnutritive sucking (NNS) and mean weight gain of all trials approached significance (p = .077, r = 0.18). In a second analysis, weight gained prior to use of PAL, during use of PAL, and post use of PAL was analyzed. Results indicated no significant difference between weight gain 1 day prior to use of PAL, the day of PAL trial, and 1 day post use of PAL. Mean weight gain for those infants who participated in 1 PAL trial was 8.49 grams for 1 day prior to use of PAL, 18.73 the day of PAL trial, and 24.81 for 1 day post use of PAL. Mean weight gain for 3 days prior to using the PAL was 10.78, 11.30 on the day of PAL trial, and 24.78 grams for 3 days post PAL use. The analyses show definite trends of greater weight gain with PAL use; however, individual variability within groups was greater than group differences leading to no significance in statistical analysis. In the third analysis the effect of proximity between premature infants' feeding schedule and PAL

    To investigate whether L-carnitine supplementation may correct nutritional carnitine deficiency and associated metabolic disturbances in premature infants receiving total parenteral nutrition, an intravenous fat tolerance test (1 gm/kg Intralipid over four hours) was performed in 29 premature infants 6 to 10 days of age (15 receiving carnitine supplement 10 mg/kg . day L-carnitine IV, and 14 receiving no supplement). Total carnitine plasma values were normal or slightly elevated in supplemented but decreased in nonsupplemented infants. In both groups, fat infusion resulted in an increase in plasma concentrations of triglycerides, free fatty acids, D-beta-hydroxybutyrate, and short-chain and long-chain acylcarnitine, but total carnitine values did not change. After fat infusion, the free fatty acids/D-beta-hydroxybutyrate ratios were lower and the increase of acylcarnitine greater in supplemented infants of 29 to 33 weeks' gestation than in nonsupplemented infants of the same gestational age. This study provides evidence that premature infants of less than 34 weeks' gestation requiring total parenteral nutrition develop nutritional carnitine deficiency with impaired fatty acid oxidation and ketogenesis. Carnitine supplementation improves this metabolic disturbance.

    Purpose To describe Type 1 retinopathy of prematurity (ROP) and its laser treatment outcomes in premature infants with birth weight > 1250 g in Eastern China. Methods A retrospective review of 3175 ROP records was conducted at Shanghai Eye & ENT Hospital of Fudan University. The records were collected at the ROP clinic from 2006 to 2014, including their demographic and medical information such as gestational age, birth weight, supplemental oxygen therapy, systemic complications, ROP stage, location, presence of plus disease. All infants were examined by RetCam fundus camera. Those with Type 1 ROP were also examined by indirect ophthalmoscope before undergoing transpupillary laser treatment. Results A total of 12 infants (24 eyes) with Type 1 ROP and birth weight > 1250 g were enrolled. All infants enrolled had plus disease and ROP in zone II retina. Specifically, 16 eyes (67%) had stage 2 ROP. 8 eyes (33%) had stage 3 ROP. ROP regressed in 23 eyes (96%) following laser treatment. Partial retinal detachment developed in one eye (4%). No severe involution sequelaes or laser-related complications were recorded. Mean follow-up was 30±6 weeks. Conclusion Type 1 ROP may occur in large premature infants who have undergone supplemental oxygen therapy. This Type 1 ROP is mainly located in zone II retina. Laser treatment is a safe and effective intervention for these infants. PMID:26674190

    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.

    Two premature infants were observed to develop behavioral and dermatologic changes and low serum zinc and copper concentrations following cessation of prolonged parenteral alimentation, while being fed exclusively with human milk. Following treatment with exogenous oral zinc supplementation, prompt relief of symptoms and increases of serum zinc and copper concentrations were observed in both infants. These patients comprise about 5% of our premature infants who are treated with parenteral alimentation for more than two weeks. We recommend that premature infants on prolonged parenteral alimentation should be monitored for changes in serum zinc and copper concentrations and, if a marked fall is observed, supplementation should be considered.

    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

    Ascorbic acid (AA), a plasma antioxidant, is maintained at high levels in premature fetal blood and declines rapidly postpartum. The sudden reduction in blood AA levels secondary to premature delivery may increase the risk of oxidant injury, that is, bronchopulmonary dysplasia and intraventricular hemorrhage. There is concern that administration of AA to premature infants, in an effort to increase antioxidant capacity, may cause hemolysis. We felt that the benefits of early AA administration and prevention of the immediate postnatal drop in blood AA levels, might outweigh the risks of erthrocyte damage. Fifty one high-risk premature infants were randomized to receive either normal saline or 100 mg/kg of AA, daily for the first week of life. Double-blind comparisons were made of hemoglobin, hematocrit, erythrocyte morphology, bilirubin, number of blood transfusions and days of phototherapy, renal function tests, the incidence of infection, bronchopulmonary dysplasia, and intraventricular hemorrhage during the first month of life. The administration of AA prevented the immediate postnatal drop in AA and was not associated with evidence of increased hemolysis. No significant differences in renal function, rate of infection, bronchopulmonary dysplasia, or intraventricular hemorrhage were seen between the two groups. This study suggests that AA administration to the premature infant is safe and supports the designing and performance of larger clinical studies of the antioxidant properties of AA.

    Aversive environment auditory stimuli is a common concern in neonatal intensive care. Recently, interest has developed regarding the use of music applications to mask such stimuli and to reduce the high risk for complications or failure to thrive. In this study of 20 oxygenated, low birth weight infants in a Newborn Intensive Care Unit of a regional medical center in the Southeastern United States, 10 infants listened to lullabies and 10 infants to recordings of their mother's voice through earphones for 20 minutes across three consecutive days. Oxygen saturation levels and frequency of oximeter alarms were recorded. Results indicated a differential response to the two auditory stimuli as listening time progressed. On Day 1, the infants listening to music had significantly higher oxygen saturation levels, but these effects disappeared by Days 2 and 3. On Days 2 and 3, however, the babies hearing music had significantly depressed oxygen saturation levels during the posttest intervals after the music was terminated. Infants hearing music had significantly fewer occurrences of Oximeter alarms during auditory stimuli than did those listening to the mothers' voice. Implications for the therapeutic use of auditory stimuli in the Newborn Intensive Care Unit are discussed.

    Eleven infants ranging 2 days to 3 months of age were studied for clinical evaluation. Ten of them were diagnosed as sepsis or suspected to be septic. Another one contracted umbilical infection. In 7 of 10 cases, causative bacteria were detected by blood culture, that is S. epidermidis in 3 cases, E. cloacae in 2 cases, K. pneumoniae in 1 case and A. calcoaceticus in another. Those infants were treated by parenteral LMOX. Dosage was 30 to 75 mg/kg per day. Clinical results were excellent in 6 cases (3 cases of S. epidermidis, 2 of E. cloacae and 1 of K. pneumoniae) and good in another case (A. calcoaceticus). The other 3 infants clinically diagnosed as sepsis but not proven by blood culture were also treated successfully. The result of the umbilical infection in 1 case was good. Another group of 5 infants ranging 4 to 22 days of age were also treated by LMOX because of suspected bacterial infections. With these infants pharmacokinetic study was done. Peak serum levels after 1 hour drip infusion of 20 mg/kg ranged from 43 to 53 micrograms/ml. Average of half-lives was 2.7 hours. Estimation of distribution volume resulted in 350 to 523 ml/kg body weight.

    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.

    Introduction In the near future, retinopathy of prematurity (ROP) will be the most significant cause of blindness in upper and middle-income countries. Due to the increasing survival chances for premature and low birth weight infants and the importance of the diagnosis and treatment of ROP, this study was aimed at determining the prevalence of ROP and its related factors in Sanandaj, Iran, in 2014. Methods This cross-sectional study was performed on 47 preterm infants, weighing less than 2000 g or with a gestational age of less than of 34 weeks. The sampling method was census. From the first examination to 1 to 4 weeks later, until retinal vascularization completion, examinations were performed by the same ophthalmologist. Data were analyzed using SPSS version 20 and frequency, mean, SD and Chi-square tests. Results The prevalence of ROP in the infants was 10.6%. Prevalence among girls was 16% and among boys it was 4.5%. The results showed that 23.5% of infants with ROP needed mechanical ventilation. The difference between the two groups was statistically significant (p = 0.031). Conclusion In this study, the prevalence of ROP in the NICU and neonatal ward of Besat Hospital in Sanandaj was low. However, due to serious consequences of the disease in premature infants, timely screening, determination, and control of risk factors provided necessary support to manage the disease. PMID:27790346

    2012-10-01

    Premature infants confront numerous physiologic and environmental stressors in the neonatal intensive care unit (NICU) that have the potential to permanently alter their neurodevelopment. Schore's regulation theory postulates that positive maternal-infant interactions can shape the infant's developmental outcomes through inducing mechanistic changes in brain structure and function. The purposes of this article are to explain the regulation of infant neurobiological processes during interactions between mothers and healthy infants in the context of Schore's theory, to identify threats to these processes for premature infants, and to propose principles of clinical practice and areas of research necessary to establish a supportive environment and prevent or reduce maladaptive consequences for these vulnerable infants. A premature birth results in the disruption of neurodevelopment at a critical time. Chronic exposure to stressors related to the NICU environment overwhelms immature physiologic and stress systems, resulting in significant allostatic load, as measured by long-term neurodevelopmental impairments in the premature infant. Positive maternal-infant interactions during NICU hospitalization and beyond have the potential to reduce neurologic deficits and maximize positive neurodevelopmental outcomes in premature infants. The quality of the maternal-infant interaction is affected not only by the infant's developing neurobiology but also by the mother's responses to the stressors surrounding a premature birth and mothering an infant in the NICU environment. Nurses can empower mothers to overcome these stressors, promote sensitive interactions with their infants, and facilitate neurodevelopment. Research is critically needed to develop and test nursing interventions directed at assisting mothers in supporting optimal neurodevelopment for their infants.

    We have previously demonstrated that very premature infants receiving glucose at 17 micromol/kg min plus appropriate supply of parenteral lipids (Intralipid) and amino acids (TrophAmine) maintained normoglycemia by glucose produced primarily via gluconeogenesis. The present study addressed the individual roles of parenteral lipids and amino acids in supporting gluconeogenesis. Fourteen premature infants (993 +/- 36 g 27 +/- 1 wk) (mean +/- SE) were studied for 8 h on d 5 +/- 1 of life. All infants were receiving standard TPN prior to the study. At start of study, the glucose infusion rate was decreased to approximately 17 micromol/kg min and either Intralipid (g + AA; n = 8) or TrophAmine (g + IL; n = 6) was discontinued. Data from 14 previously studied infants receiving glucose (approximately 17 micromol/kg min) + TrophAmine + Intralipid (g + AA + IL) are included for comparison. Gluconeogenesis was measured by [U-13 C]glucose, (g + AA) and (8 infants of the g + AA + IL group) or [2-13C]glycerol, (g + IL) and (6 infants of the g + AA + IL group). Infants studied by the same method were compared. Withdrawal of Intralipid resulted in decreased gluconeogenesis, 6.3 +/- 0.9 (g +AA) vs. 8.4 +/- 0.7 micromol/kg min (g + AA + IL) (p = 0.03). Withdrawal of TrophAmine affected neither total gluconeogenesis, 7.5 +/- 0.8 vs. 7.9 +/- 0.9 micromol/kg min nor gluconeogenesis from glycerol, 4.4 +/- 0.6 vs. 4.9 +/- 0.7 micromol/kg min (g+ IL and g + AA + IL groups, respectively). In conclusion, in parenterally fed very premature infants, lipids play a primary role in supporting gluconeogenesis.

  7. Premature singleton versus a twin or triplet infant death: parental adjustment studied through a personal interview.

    Parental adjustment following the death of a premature singleton or multiple birth infant has hitherto been studied by mailed questionnaires or telephone survey. In the present study, using an in-depth personal interview, grief reactions and adjustment patterns of nine families who lost a singleton premature infant ('Single Group') were compared with those of nine families who lost one of a premature multiple birth cohort ('Multiple Group'). The interview was conducted 1-4 years after the death of the infant and evaluated specific areas or 'scales' of life adjustment, including individual feelings, relationship between husband and wife, and functioning at home and at work. There was no significant difference between the paternal and maternal level of adjustment of the two groups in any of the studied scales. A positive correlation was found between maternal and paternal grief reaction of the same family in the scales of individual feelings (r = 0.65), relationships between husband and wife (r = 0.70), and functioning at home (r = 0.57). Comparing the father's scale with the mother's scale revealed a significant difference only in the area of 'individual feelings'. The gestational age, maternal bonding during hospitalisation of the infant and the parental attendance at the event of death were significantly associated with the process of parental adjustment. The results of this study support previous reports of similar parental reactions following the demise of a premature singleton or multiple birth infant. Since societal environment may not recognise the need for consolation of these families, care, compassion, and sensitivity should be encouraged in dealing with these parents at the time of their infant' death, and for a long time thereafter.

    2000-03-01

    The physiological and behavioural effects of music during recovery from heel lance were examined in 14 preterm infants at 29 to 36 weeks post-conceptual age (PCA). Infants were tested on 2 occasions: during a music condition and during a no-music control condition. Each condition was videotaped during 3 periods: baseline, heel lance, and recovery. Infants were divided into 2 age groups for data analyses: less than and greater than 31 weeks PCA. Mixed model ANOVAs showed that heel lance elicited a stress response (i.e., increased heart rate, decreased oxygen saturation, increased state-of-arousal, and increased facial actions indicative of pain) in both age groups. The stress response was greater in the older group. During recovery, the older group had a more rapid return of heart rate, behavioural state, and facial expressions of pain to baseline levels in the presence of compared to the absence of music. It was concluded that music is an effective NICU intervention following a stress-provoking stimulus in infants older than 31 weeks PCA.

    Parents who are at risk for giving birth to an extremely premature infant, defined as 22 to 25 weeks' gestation, can find themselves faced with urgent treatment decisions for their unborn infant that have life-altering consequences. Despite the recommendation for involving parents in decision making for these infants, there is limited evidence regarding guidelines for involving parents. In this article, we describe a case from a larger collective case study that examines the decision making and the decision support needs of parents regarding life support decisions made over time (prenatally and postnatally) for extremely premature infants from the perceptions of parents, physicians, and nurses. For this case study, we describe decisions that were made during the antenatal hospitalization of the mother whose infant was stillborn, the support the parents received, and advice for healthcare professionals for improving care to families. For this case, the mother and father, a physician, and 2 nurses were interviewed before the birth of the infant. The findings in this case study demonstrate the importance of the nurse being present when information is given to parents, of informing with compassion, and helping parents to understand treatment options and decisions.

    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

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

    PubMed

    Baumgart, S

    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

  13. Factors influencing plasma renin and renin substrate in premature infants.

    Concentrations of plasma renin (PRC) and plasma renin substrate (PRS) were measured during the first week of life in 52 infants born at less than 37 weeks' gestation (mean (SEM) gestation 30 (0.4) weeks, mean (SEM) birth weight 1.35 (0.08) kg). Both PRC (median 35, interquartiles 16.3, 94.5 ng/ml/hour) and PRS (median 2.3, interquartiles 1.3, 5.0 micrograms/ml) were raised compared with adults. The proportional rise in PRC was much greater than that in PRS, suggesting that PRS may be rate limiting in the generation of angiotensin I. Log10 PRC was inversely proportional to gestational age and a high urinary sodium loss was associated with a significantly raised log10 PRC. In hypoxaemic infants, there was a strong correlation between log10 PRS and haemoglobin concentration; this is a new observation in human infants but consistent with data available from other species.

    Objective To define changes of heart rate variability in premature infant with hydrocephalus before and after drainage procedure. Study Design The authors report a case of a premature infant with hydrocephalus with analysis of heart rate variability before and after drainage procedure. Three subsequent recordings of the electrocardiography and heart rate variability were done: the first at the age of 22 days before insertion of ventriculoperitoneal shunt, the second at the age of 36 days with functional shunt, the third at the age of 71 days (before discharge). Results Before drainage operation, there was reduced heart rate variability in time and spectral domains, and sympathetic activity was dominant. After surgery, an increase in heart rate variability parameters was found, particularly with spectral analysis. The ratio of low-frequency/high-frequency band and relative power of the low-frequency band decreased, reflecting enhanced parasympathetic activity. Conclusion Results of the heart rate variability analysis in a preterm infant with hydrocephalus before and after drainage procedure showed marked improvement in chronotropic cardiac regulation. Evaluation of heart rate variability in premature infants with hydrocephalus with increased intracranial pressure can be an additional method for monitoring of cardiac dysregulation and improvement of the cardiovascular control after successful drainage procedure.

    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.

    Acute kidney injury (AKI) is common in premature infants and is associated with poor outcomes. Novel biomarkers can detect AKI promptly. Because premature infants are born with underdeveloped kidneys, baseline biomarker values may differ. We describe baseline values of urinary neutrophil gelatinase-associated lipocalin (NGAL), IL-18, kidney injury molecule-1 (KIM-1), osteopontin (OPN), beta-2 microglobulin (B2mG), and Cystatin-C (Cys-C). Next, we test the hypothesis that these biomarkers are inversely related to GA. Candidate markers were compared according to GA categories in 123 infants. Mixed linear regression models were performed to determine the independent association between demographics/interventions and baseline biomarker values. We found that urine NGAL, KIM-1, Cys-C, and B2mG decreased with increasing GA. With correction for urine creatinine (cr), these markers and OPN/cr decreased with increasing GA. IL-18 (with or without correction for urine creatinine) did not differ across GA categories. Controlling for other potential clinical and demographic confounders with regression analysis shows that NGAL/cr, OPN/cr, and B2mG/cr are independently associated with GA. We conclude that urine values of candidate AKI biomarkers are higher in the most premature infants. These findings should be considered when designing and analyzing biomarker studies in newborn with AKI.

    2014-01-01

    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

    The study was set out to investigate whether the Marcovich model of a "soft treatment" of premature infants encourages the parent-infant-relationship to such an extent that, at school age, the Marcovich-children would be found to differ significantly from children treated with standard care with regard to the quality of their attachment and the prevalence of emotional and behavioural disorders. The Marcovich-children of the present sample had been discharged from hospital much earlier than the standard group, they were less frequently treated with artificial respiration, infant-parent body contact was encouraged significantly earlier, and, although they were less frequently breast-fed, those who were breast-fed were allowed to do so at a much earlier stage. The Marcovich-children were found to display higher social competence, more emotional openness, more emotional coherence, less dismissal of attachment and less preoccupied anger. The two samples did not differ with regard to their total attachment quality as well as their emotional and behavioural problems. The fact that no significant differences could be established with regard to the quality of the attachment suggests that the complex life-saving attachment system is not irreversibly affected by the early separation and distress and that the months and years after the hospital stay have the power to make up with any experienced trauma. It seems, however, that special aspects of the attachment system, such as the communication and interaction, are positively encouraged and enhanced by the soft treatment of the premature infant, which leads to greater emotional openness and social competence, as well as less preoccupied anger against the attachment figures.

  20. The biological clock of very premature primate infants is responsive to light

    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

    Preterm births occurs in 6-12% of all pregnancies, accounts for 75% of neonatal death and causes significant neonatal morbidity. A large number of preterm birth is associated with infection (30%), because of the release of many cytokines. In fact acute chorioamnionitis represents the inflammatory response to extracellular microorganisms that gain access to the gestational sac. Clinical signs of infection compare in the 12% of cases, while the prevalence of positive amniotic fluid cultures is approximately 50% in patients with preterm PROM. Despite the recent studies about the dosage of inflammatory biomarkers in the amniotic fluid or in fetal and maternal blood, placenta histology remains the gold standard for the diagnosis of chorioamnionitis. Histological chorioamnionitis describes the progression of the inflammatory process. Organisms first colonise the chorioamnionic surface. Then, the neutrophils migrates to the chorion (chorionitis) and to the amnion (chorioamnionitis) and, in the last stage, amnionic epithelial cells undergo necrosis (necrotising chorioamnionitis). It represents the mother inflammatory response and it differs from the fetal inflammatory response (funisitis). Funisitis first appears in vessels of the chorionic plate (chorionic vasculitis) or in the umbilical vein (umbilical phlebitis), then in the umbilical artery (umbilical arteritis), and in the Wharton's jelly (umbilical perivasculitis). The fetal inflammatory response has been associated with inflammatory diseases of preterm infants, increasing the risk of neonatal sepsis and meningitis, bronchopulmonary dysplasia and cerebral palsy. We present our experience on the relationship between histological chorioamnionitis, preterm birth and inflammatory diseases of VLBW infants.

    A prominent theoretical view is that the brain is inherently predictive [1, 2] and that prediction helps drive the engine of development [3, 4]. Although infants exhibit neural signatures of top-down sensory prediction [5, 6], in order to establish that prediction supports development, it must be established that deficits in early prediction abilities alter trajectories. We investigated prediction in infants born prematurely, a leading cause of neuro-cognitive impairment worldwide [7]. Prematurity, independent of medical complications, leads to developmental disturbances [8-12] and a broad range of developmental delays [13-17]. Is an alteration in early prediction abilities the common cause? Using functional near-infrared spectroscopy (fNIRS), we measured top-down sensory prediction in preterm infants (born <33 weeks gestation) before infants exhibited clinically identifiable developmental delays (6 months corrected age). Whereas preterm infants had typical neural responses to presented visual stimuli, they exhibited altered neural responses to predicted visual stimuli. Importantly, a separate behavioral control confirmed that preterm infants detect pattern violations at the same rate as full-terms, establishing selectivity of this response to top-down predictions (e.g., not in learning an audiovisual association). These findings suggest that top-down sensory prediction plays a crucial role in development and that deficits in this ability may be the reason why preterm infants experience altered developmental trajectories and are at risk for poor developmental outcomes. Moreover, this work presents an opportunity for establishing a neuro-biomarker for early identification of infants at risk and could guide early intervention regimens.

    Background: Intraventricular haemorrhage (IVH) and periventricular leucomalacia (PVL) in premature infants presumably have many causes. It has been proposed that inflammatory processes in the fetomaternal unit play an important role in the pathogenesis of these lesions. Objective: To study the correlation of postpartum serum interleukin 6 (IL6) concentration as a marker of inflammation and neonatal cerebral morbidity in preterm infants < 28 weeks of gestational age. Methods: A total of 88 infants were grouped according to maximum serum IL6 levels within 12 hours post partum: group A (n = 50), ⩽ 100 pg/ml; group B (n = 38), > 100 pg/ml. Ultrasound studies and clinical assessment were performed routinely. Results: IVH was noted significantly more often in group B (24/38; 63%) than in group A (19/50; 38%) (p = 0.02). In a multiple logistic regression model, raised serum IL6 independently predicted development of severe IVH (odds ratio 8.4; 95% confidence interval 2.85 to 24.9; p = 0.0001). Conclusions: Raised serum IL6 may serve as a marker for severe IVH in infants < 28 weeks of gestational age. Although cerebral morbidity in premature infants is determined by different variables, the identification of systemic inflammation can help to define the need for anti-inflammatory strategies to prevent cerebral morbidity.

    The proposed outcomes for C.Q. were achieved. Communication between dietician, neonatal intensive care and pediatric nursing staff, pediatric nephrology nurses and physicians played a critical role in providing optimal care for C.Q. Due to her multiple problems, it was imperative that all disciplines collaborate and coordinate their care. The meticulous supervision by the staff nurses allowed this tiny patient to overcome her multiple problems. Careful follow-up included monitoring nutritional markers, laboratory results, and adequacy of dialysis. It is also important to note that open communication by the nephrology nurses allows small patients like C.Q. to have enhanced quality of life at home with their families. C.Q. is now a thriving infant, cared for by her mother at home.

    We report the case of a premature newborn child (36 weeks) who was operated on a teratoma of the sacrum when he was 12 days old and weighed 2,950 g. The patient presented a late postoperative apnea 17 hours after anesthesia. The anesthetic technique consisted of lumbar epidural blockade with 0.33% bupivacaine at a dose of 2.25 ml and superficial inhalation anesthesia with 0.5% isoflurane. Relaxing muscular agents used in this case were succinylcholine (3 mg) for orotracheal intubation and pancuronium bromide (0.3 mg) for maintaining the anesthetic level. The immediate postoperative phase was uneventful but 17 hours after surgery the patient presented apnea, bradycardia (40 beats/min), and marked cyanosis requiring assisted ventilation with bag and mask during 3 min and initial cardiac massage. Recovery of heart rate was immediate and recovery of ventilation was progressive. The patient was treated with caffeine during one week and no relapses occurred. Pneumocardiographic recordings obtained later on revealed sporadic short lasting episodes of apnea (shorter than 15 s) sometimes associated with bradycardia (40 beats/min lower than baseline). There were no apparent intercurrent or precipitating factors for this apnea. We believe that the present clinical picture corresponds to a late postoperative apnea of unknown origin which required reanimation measures and that until present, there are no reported complications of the anesthetic technique that can explain this episode.

    The more than 3,000 deaths of premature infants due to low weight in Taiwan cause deep personal grief in their parents, for whom there is no pain greater than losing a child. This loss, nearly always sudden and unexpected, is an issue often ignored by clinic nursing staff. The purpose of this paper was to consider various grief counseling theories in order to help nurses attend to the grief counseling needs of parents who lose a premature infant. Better understanding of parents' grief responses by nursing staffs will help nurses to accept and address such. Grief processes identified include: shock and numbness, searching and yearning, disorientation and reorganization. Grief responses include: feel, physiology and sense organs, cognition and behavior. The four tasks essential to grief recovery include: to accept the reality of the loss, to work through the pain of grief, to adjust to an environment in which the deceased is missing, and to emotionally relocate the deceased and move on with life. Coaching through grief counseling theory puts forward and looks after concrete measures, and provides three suggestions for the parents who lose a premature infant. These can be used as reference by clinical staffs, help promote nursing staff understanding of this topic, help improve care for grieving parents and improve care quality.

    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

    This article provides a synopsis of a series of studies exploring the effects of TAC-TIC (Touching And Caressing-Tender In Caring) therapy with premature infants. Study 1 looked at the short and long-term effects and found enhanced mental development in the stroked infants at 15 months. In study 2 the physiological effects of an abbreviated version of TAC-TIC with high-risk ventilated infants were examined and it was concluded that TAC-TIC exerted no harm to these vulnerable infants. The behavioural reactions of a sample of premature and low birthweight infants to TAC-TIC and parental responses to administering it were explored in study 3. The infants were found to respond predominantly with arm and leg movements to TAC-TIC while fathers and mothers reported enjoying performing TAC-TIC and elicited a similar pattern and frequency of behavioural reactions. In study 4 the question of whether TAC-TIC benefits preterm infant learning and/or sucking behaviour was investigated. The conclusion reached was that TAC-TIC may potentially benefit cognitive performance within the neonatal period and that this may be an early indicator of long-term cognitive gains reported by previous studies. Using a matched subjects design, study 5 explored the impact of TAC-TIC upon the digestive system by analysing gastric aspirates before and after TAC-TIC and a control period of time. It was concluded that TAC-TIC appeared to induce a more suitable stomach environment for digestion.

    Chorioamnionitis and elevated cord blood inflammatory cytokine concentrations are associated with detectable disturbances of systemic and cerebral hemodynamics in premature newborns. Fifty-five infants (25-31 wk gestation) were enrolled. Chorioamnionitis was defined by placental histology. IL-6, IL-1beta, and tumor necrosis factor-alpha were quantified by ELISA. Blood pressure, heart rate, cardiac output, stroke volume, fractional shortening, and middle cerebral artery blood flow velocities were measured at 3 +/- 1 h after birth. Chorioamnionitis was evident in 22 placentas and was associated with increased IL-6 (p < 0.001), IL-1beta (p = 0.035), and heart rate (p = 0.027); and with decreased mean and diastolic blood pressure (p = 0.026 and p = 0.019, respectively). IL-6 concentration correlated inversely with systolic, mean, and diastolic blood pressures. Right ventricular cardiac output was elevated (p = 0.028) in infants with fetal vessel inflammation. Maternal temperature >or=38.0 degrees C and newborn immature-to-total white blood cell ratio >or=0.4 were associated with significant decreases in left ventricular fractional shortening (p = 0.001 and p = 0.005, respectively). Neither chorioamnionitis nor elevated cytokine concentrations were associated with changes in middle cerebral artery Doppler blood flow velocities. Chorioamnionitis and elevated cord blood IL-6 concentrations are associated with decreased blood pressure in premature newborns. Inflammation of the fetal vessels and nonspecific indicators of infection are associated with disturbances in cardiac function. Infants with chorioamnionitis and elevated cytokine concentrations do not manifest changes in cerebral Doppler indices within the first few postnatal hours. We speculate that cytokine-associated systemic hemodynamic disturbances in premature infants born after chorioamnionitis predispose such infants to perinatal brain injury.

    Purpose To report our findings in an infant with Peters anomaly type II whose retinopathy of prematurity (ROP) was treated with an anti-VEGF agent and surgeries. Case Report A male infant weighing 548 g was born prematurely at 23 weeks and 1 day with corneal opacity and shallow anterior chambers in both eyes. At the postmenstrual age of 35 weeks and 3 days, the infant was tentatively diagnosed with stage 3 ROP because of a dilated tunica vasculosa lentis and ultrasonographic findings. The boy was treated with bilateral intravitreal injections of bevacizumab (IVB) because laser photocoagulation of the retina could not be performed due to the corneal opacity. The retina in the right eye detached 3 times, namely 5 days, 16 days, and 7 months after the IVB; encircling the scleral buckle and a vitrectomy with endolaser photocoagulation were therefore required. In his left eye, the retina was reattached after the initial IVB, and no additional treatment was required. ROP was not reactivated in both eyes until the last examination at the age of 2 years and 6 months. Conclusions Our results showed that IVB is a useful treatment for ROP in patients with Peters anomaly. However, a retinal detachment can be a complication after IVB. The optimal timing of IVB for ROP in infants with hazy media needs to be determined. PMID:25408672

    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%

    In this randomized, controlled multi-site study, the pacifier-activated-lullaby system (PAL) was used with 68 premature infants. Dependent variables were (a) total number of days prior to nipple feeding, (b) days of nipple feeding, (c) discharge weight, and (d) overall weight gain. Independent variables included contingent music reinforcement for non-nutritive sucking for PAL intervention at 32 vs. 34 vs. 36 weeks adjusted gestational age (AGA), with each age group subdivided into three trial conditions: control consisting of no PAL used vs. one 15-minute PAL trial vs. three 15-minute PAL trials. At 34 weeks, PAL trials significantly shortened gavage feeding length, and three trials were significantly better than one trial. At 32 weeks, PAL trials lengthened gavage feeding. Female infants learned to nipple feed significantly faster than male infants. It was noted that PAL babies went home sooner after beginning to nipple feed, a trend that was not statistically significant.

    Premature infants are fed by gavage tube before 34 weeks adjusted gestational age and when nipple feeding results in detrimental changes in respiration and heart rate. Nipple feeding skill must be developed and correlates with length of hospitalization and neurobehavioral development. This study provided music reinforcement for nonnutritive sucking and assessed nipple feeding rates pre- and posttreatment for 32 infants referred as poor feeders. A pacifier fitted with a pressure transducer activated 10 seconds of recorded music in a one-trial, 15-minute intervention given to experimental infants (n = 16) 30 to 60 minutes before the late afternoon bottle feeding. Feeding rates were collected for bottle feedings pre- and postintervention and for a similar interval for a no-contact control group (n = 16). Results showed that the intervention significantly increased feeding rates. Music functioned as reinforcement and the sucking behavior transferred from a nonnutritive to a nutritive event.

    To determine whether salivary amylase of premature infants can function as a surrogate for pancreatic amylase, we evaluated its production in the infant, acid resistance, and hydrolytic potency in a simulated oropharyngeal, gastric, and intestinal environment. The activity of salivary amylase in 11 prematures varied between 1 and 33 U/ml; the isozymic profile and acid resistance of the premature salivary amylase were identical to those of the enzyme of adults. A "modular" formula containing 7 g/dl of a 14C labeled long chain glucose polymer with degrees of polymerization ranging between 18 and 29 glucose units was prepared. Salivary amylase, 1.1 U/ml, was added to this formula. The progressive breakdown of the 14C polymers as the milk was subjected to oropharyngeal, gastric, and intestinal phase environments was evaluated by quantifying the liberation of short-chain oligomers from the 14C labeled substrates. The gastric pH was varied between 2 and 5 and the gastric incubation time was either 5 or 180 min. Substantial gastric phase breakdown only occurred after 3 h of exposure at the higher pHs of 4 (12%) and 5 (32%). During the intestinal phase, salivary amylase activity resumed. Prior gastric phase pH affected ultimate intestinal phase breakdown, p less than 0.001; after 5-min gastric phases at pHs ranging from 2 to 5, the intestinal phase breakdown ranged from 17 to 55%. We conclude that the limited salivary amylase in the saliva of premature infants can produce significant glucose polymer digestion in both the stomach and small intestine but the digestion falls substantially short of that accomplished by usual concentrations of pancreatic amylase.

    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 use of human milk fortifiers (HMF) helps to meet the high nutritional requirements of the human milk-fed premature infant. Previously available powdered products have not met the protein requirements of the preterm infant population and many neonatologists add powder protein modulars to help meet protein needs. The use of powdered products is discouraged in neonatal intensive care units (NICU) due to concern for invasive infection. The use of a commercially available acidified liquid product with higher protein content was implemented to address these two concerns. During the course of this implementation, poor growth and clinically significant acidosis of infants on Acidified Liquid HMF (ALHMF) was observed. The purpose of this study was to quantify those observations by comparing infant outcomes between groups receiving the ALHMF vs. infants receiving powdered HMF (PHMF). A retrospective chart review compared outcomes of human milk-fed premature infants<2000 g receiving the ALHMF (n=23) and the PHMF (n=46). Infant growth, enteral feeding tolerance and provision, and incidence of necrotizing enterocolitis (NEC), metabolic acidosis, and diaper dermatitis were compared between the two groups. No infants were excluded from this study based on acuity. Use of ALHMF resulted in a higher incidence of metabolic acidosis (p=0.002). Growth while on HMF as measured in both g/kg/day (10.59 vs. 15.37, p<0.0001) and in g/day (23.66 vs. 31.27, p=0.0001) was slower in the ALHMF group, on increased mean cal/kg/day (128.7 vs. 117.3, p=0.13) with nearly twice as many infants on the ALHMF requiring increased fortification of enteral feedings beyond 24 cal/ounce to promote adequate growth (48% vs. 26%, p=0.10). Although we were not powered to study NEC as a primary outcome, NEC was significantly increased in the ALHMF group. (13% vs. 0%, p=0.03). Use of a LHMF in an unrestricted NICU population resulted in an increase in clinical complications within a high-acuity NICU, including

    The purpose of this study was twofold: (a) to examine extant research in the field of music with premature and full term infants in order to identify protocols being used in the presentation of musical stimuli to neonates and (b) to use knowledge gleaned from audiology as a basis for suggesting a standardized protocol for use of musical stimuli with infants. Articles considered appropriate for inclusion in the analysis met the following criteria: (a) presented data for the effects of music on a dependent measure, (b) had subjects who were identified as either premature or term newborns receiving treatment after birth and prior to discharge from the hospital, and (c) used music for some or all of the aural stimuli. Articles (N = 20) were categorized by demographic information, types of aural stimuli, independent variables, dependent measures, and protocol used to present the musical stimuli. Of primary importance to this study was the protocol used in each study to present musical stimuli. Data regarding total duration of stimuli per day, longest duration of stimuli per day, method of stimuli presentation, placement of speakers, decibel level of stimuli, and where;he decibel level was measured reveal that there is no standard protocol being followed with regard to the presentation of aural stimuli. Recommendations include future research on (a) determining a minimum gestational age where music therapy may be appropriate, (b) determining the frequency spectrum perceived by a premature infant, (c) determining the decibel levels reaching the ear drum and assessing appropriate levels for minimum stimulation with maximum results, and (d) carefully considering the method of stimulus presentation as it will have an impact on the decibel level reaching the ear drum of these infants.

    Background: Continuous high-intensity noise in the Neonatal Intensive Care Unit (NICU) is stressful for premature infants and its reduction is considered as a nursing care. This study aimed to evaluate the effects of earmuffs’ use on the physiologic and motor responses of premature infants. Materials and Methods: This is a clinical trial conducted on 64 premature infants admitted to the NICU, who met the inclusion criteria, and were randomly assigned to study and control groups. Earmuffs were used for premature infants for 2 h in the morning and 2 h in the afternoon for two consecutive days to reduce the noise intensity in the busiest time of the NICU. The group with earmuff (study group) was compared with the control group receiving only routine care. Infants’ physiologic and motor responses were observed before, during, immediately, and 1 h after the intervention. Analysis of covariance and repeated measure analysis of variance (ANOVA) were used to analyze the data. Results: When infants wore the earmuffs, they had significantly higher mean arterial oxygen saturation, the less frequent motor response, and a decrease in their pulse and respiratory rate. Conclusion: Paying attention to environmental noise can help the patients, especially the neonates in the NICU, and can be considered as a nursing care. Wearing earmuffs can protect premature infants against noise in the NICU and improve their physiological and motor state. PMID:24834077

    Retinopathy of Prematurity (ROP) is a major risk for permanent visual loss in extreme prematures. In stage 3+ (zone I and II), defined as threshold disease, the risk for retinal detachment with subsequent blindness is about 50% without treatment, compared to only a few percent with laser photoablation. Visualisation and interpretation of the critical retinal changes requires a high degree of expertise. Therefore, screening by general ophthalmologists will not identify all cases at threshold necessary to prevent blindness in as many infants as possible. The development of a new digital wide-field camera system (RetCam 120) allows documentation of nearly the entire retina within minutes. Recently, sensitivity, specificity, positive predictive power and negative predictive power have been evaluated to be high. Data collection is also possible by trained staff of the neonatal care units. Data can be transferred electronically, even though it could be transferred through physical transport. Analyzing the data in a central reading center specialized in the treatment of ROP will allow optimal timing of treatment and thus salvage vision in more infants. In addition, unnecessary referrals that are not only expensive but put also stress on the very vulnerable prematures can be avoided. At present, efforts are made to realize a pilot project in Eastern Bavaria that will test the potentials of telemedicine based screening for ROP. In addition, the potential of the system will be evaluated in other neuroophthalmological diseases.

    2002-08-01

    Non-oliguric hyperkalaemia is a common and serious complication of extreme prematurity, resulting from a potassium loss from the intra- into the extracellular space during a specific post-natal period. Treatment of this disorder has been adapted from the treatment of hyperkalaemia in renal failure, an entity of completely different pathophysiology. A few years ago, the administration of salbutamol, which induces cellular potassium uptake, was proposed as a new therapeutic option. In this review article we discuss the pathogenesis and current therapy of non-oliguric hyperkalaemia of the premature infant, with special emphasis on the presently available knowledge and concerns with regard to the use of salbutamol. Being aware of the paucity of studies on non-oliguric hyperkalaemia, we propose treatment recommendations which are based on best available evidence. These comprise the administration of calcium, infusion of insulin plus glucose, correction of acidosis, and exchange transfusion or peritoneal dialysis as a last resort therapy. Before controlled trials on efficacy of salbutamol treatment of non-oliguric hyperkalaemia of the premature infant can be initiated, more data on safety are needed.

    Studies were carried out on the in vivo kinetics and clinical efficacy of latamoxef (LMOX) in neonates and premature infants. The results are summarized below. Serum concentration and T1/2 following intravenous injection of LMOX to neonates LMOX was intravenously administered to neonates as one shot doses of 10 mg/kg and 20 mg/kg. The serum concentration of LMOX showed a dose-response to the 10 and 20 mg/kg doses in each of the 0--3 day-old group, 4--7 day-old group and 8--28 day-old group. The T 1/2 values were as follows; for the 10 mg/kg dose, 5.17 hours in the 0--3 day-old group, 3.28 hours in the 4--7 day-old group and 2.79 hours in the 8--28 day-old group; for the 20 mg/kg dose, 5.58 hours in the 0--3 day-old group, 3.46 hours in the 4--7 day-old group and 3.14 hours in the 8--28 day-old group. Thus, it is seen that the half-life of both dosages decreased as the infants became older. Serum concentration and T 1/2 following intravenous injection of LMOX to premature infants Similar to the case of neonates described above, the concentration of LMOX in the serum of the premature infants showed a dose-response to the 10 mg/kg and 20 mg/kg dosages. The T 1/2 values for the 0--3, 4--7 day-old and 8--28 day-old groups were 7.54, 3.93 hours and 6.25 hours, respectively, for the 10 mg/kg dose, and 10.8, 4.05 hours and 3.23 hours, respectively, for the 20 mg/kg dose. Again, it is seen that the half-life of both dosages decreased as the age of the prematurely-born infants increased. Serum concentration and T1/2 following 1-hour intravenous drip infusion of LMOX to neonates LMOX was administered to neonates in doses of 10 mg/kg and 20 mg/kg, by i.v. drip infusion over a 1-hour period. With both dosages, the peak serum concentration of LMOX occurred at the time of completion of the infusion. The T1/2 values for the 0--3, 4--7 day-old and 8--28 day-old groups were 5.41, 3.68 hours and 1.92 hours, respectively, for the 10 mg/kg dose, and 5.31, 2.67 hours and 4.86 hours

    Conventional magnetic resonance imaging (MRI) at term equivalent age (TEA) is suggested to be a reliable tool to predict the outcome of very premature infants. The objective of this study was to determine simple reproducible MRI indices, in premature infants and to analyze their neonatal determinants at TEA. A cohort of infants born before 32 weeks gestational age (GA) underwent a MRI at TEA in our center. Two axial images (T2 weighted), were chosen to realize nine measures. We defined 4 linear indices (MAfhlv: thickness of lateral ventricle; CSI: cortex-skull index; VCI: ventricular-cortex index; BOI: bi occipital index) and 1 surface index (VS.A: volume slice area). Perinatal data were recorded. Sixty-nine infants had a GA (median (interquartile range)) of 30.0 weeks GA (27.0; 30.0) and a birth weight of 1240 grams (986; 1477). MRI was done at 41.0 (40.0; 42.0) weeks post menstrual age (PMA). The inter-investigator reproducibility was good. Twenty one MRI (30.5%) were quoted abnormal. We observed an association with retinopathy of prematurity (OR [95CI] = 4.205 [1.231–14.368]; p = 0.017), surgery for patent ductus arteriosus (OR = 4.688 [1.01–21.89]; p = 0.036), early onset infection (OR = 4.688 [1.004–21.889]; p = 0.036) and neonatal treatment by cefotaxime (OR = 3.222 [1.093–9.497]; p = 0.03). There was a difference for VCI between normal and abnormal MRI (0.412 (0.388; 0.429) vs. 0.432 (0.418; 0.449); p = 0,019); BOI was higher when fossa posterior lesions were observed; VS.A seems to be the best surrogate for cerebral volume, 80% of VS.As’ variance being explained by a multiple linear regression model including 7 variables (head circumference at birth and at TEA, PMA, dopamine, ibuprofen treatment, blood and platelets transfusions). These indices, easily and rapidly achievable, seem to be useful but need to be validated in a large population to allow generalization for diagnosis and follow-up of former premature infants.

    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

    OBJECTIVES: To determine variations in neonatology practice regarding the diagnosis and management of patent ductus arteriosus (PDA) in premature infants. DESIGN: Standardized telephone interview of preferences and practices. SUBJECTS: Canadian neonatologists in active clinical practice. RESULTS: Of 136 eligible Canadian neonatologists, 100 respondents (74%) estimated the proportion of infants with suspected PDA who have echocardiography to be a median of 80% (range 0% to 100%), with considerable variation both within and between centres. Only two centres had written guidelines. More recent medical school graduates were significantly more likely to use echocardiography. Increased use of echocardiography was also significantly related to increased availability. Fluid restriction and indomethacin was used as initial therapy by 89% of respondents, with the indomethacin dose standardized for 83%; surgical ligation was used when indomethacin therapy was contraindicated or had failed. Personal guidelines directed decisions regarding therapy for the majority of neonatologists. CONCLUSIONS: Among Canadian neonatologists, there is considerable variation regarding practices related to the diagnosis and management of PDA in premature infants. This variation may potentially affect the cost effectiveness of care for these patients. PMID:20401223

    Objective: Inhaled nitric oxide (iNO) is a potential new therapy for prevention of bronchopulmonary dysplasia and brain injury in premature infants. This study examined dose-related effects of iNO on NO metabolites as evidence of NO delivery. Study Design: A subset of 102 premature infants in the NO CLD trial, receiving 24 days of iNO (20 p.p.m. decreasing to 2 p.p.m.) or placebo, were analyzed. Tracheal aspirate (TA) and plasma samples collected at enrollment and at intervals during study gas were analyzed for NO metabolites. Result: iNO treatment increased NO metabolites in TA at 20 and 10 p.p.m. (1.7- to 2.3-fold vs control) and in plasma at 20, 10, and 5 p.p.m. (1.6- to 2.3-fold). In post hoc analysis, treated infants with lower metabolite levels at entry had an improved clinical outcome. Conclusion: iNO causes dose-related increases in NO metabolites in the circulation as well as lung fluid, as evidenced by TA analysis, showing NO delivery to these compartments. PMID:19812581

    This study assessed music as reinforcement for non-nutritive sucking of 12 premature infants born at an average gestation of 29.3 weeks and an average birthweight of 1111.9 g. At the time of the study, the infants' average post conception age was 35.5 weeks, and their average weight was 1747.3 g. A pacifier was fitted with a pressure transducer so that a sufficient suck activated frequency and duration signals as well as 10 seconds of recorded music consisting of lullabies sung by female vocalists. A 14-minute ABAB study design included a silence baseline for 2 minutes, 5 minutes of contingent music, 2 minutes of silence, and 5 minutes of contingent music. Frequency data were recorded for each 5-second interval in which the duration light was activated for at least 3 seconds. Results demonstrated that sucking rates during the periods of contingent music were 2.43 times greater than baseline (silence) sucking rates. In this study, music contributed significantly to the development of non-nutritive sucking of premature infants.

    Brain injury in the premature infant, a problem of enormous importance, is associated with a high risk of neurodevelopmental disability. The major type of injury involves cerebral white matter and the principal cellular target is the developing oligodendrocyte. The specific phase of the oligodendroglial lineage affected has been defined from study of both human brain and experimental models. This premyelinating cell (pre-OL) is vulnerable because of a series of maturation-dependent events. The pathogenesis of pre-OL injury relates to operation of two upstream mechanisms, hypoxia-ischemia and systemic infection/inflammation, both of which are common occurrences in premature infants. The focus of this review and of our research over the past 15-20 years has been the cellular and molecular bases for the maturation-dependent vulnerability of the pre-OL to the action of the two upstream mechanisms. Three downstream mechanisms have been identified, i.e., microglial activation, excitotoxicity and free radical attack. The work in both experimental models and human brain has identified a remarkable confluence of maturation-dependent factors that render the pre-OL so exquisitely vulnerable to these downstream mechanisms. Most importantly, elucidation of these factors has led to delineation of a series of potential therapeutic interventions, which in experimental models show marked protective properties. The critical next step, i.e., clinical trials in the living infant, is now on the horizon.

    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

  11. Pain-associated stressor exposure and neuroendocrine values for premature infants in neonatal intensive care.

    Recurrent stress during neonatal intensive care taxes the adaptive capacity of the premature infant and may be a risk factor for suboptimal developmental outcomes. This research used a descriptive, cross-sectional design and a life course perspective to examine the relationship between resting adrenocorticoid values at 37 postmenstrual weeks of age and cumulative pain-associated stressor exposure in prematurely born infants. Subjects were 59 infants born at under 35 completed weeks of gestation, who were at least 2 weeks of age, and who had been cared for in the NICU since birth. No significant relationships were identified between cortisol values and any of the study variables (number of skin breaking procedures, hours of assisted ventilation, gestational age at birth, exposure to antenatal steroids, history of severe academia, birthweight, days of age to attain birthweight, weight at testing, days of age at testing, recent pain-associated procedures, and 17-OHP value). A significant negative correlation (Spearman rank, one-tailed) between the number of skin-breaking procedures and 17-OHP values was identified (r = -.232, p = .039). Recurrent pain-associated stressor exposure may be a more important factor in explaining the variance of 17-OHP values at 37 postmenstrual weeks of age than birthweight, gestational age, or chronological age.

    To assess the benefits of lullaby singing and multimodal stimulation on premature infants in neonatal intensive care, 40 infants in a Level III Newborn Intermediate Care Unit were divided into control (n = 20) and experimental (n = 20) groups by pair matching on the basis of gender, birthweight, gestational age at birth and severity of medical complications. Participants met these project criteria: (a) corrected gestational age > 32 weeks; (b) age since birth > 10 days; and (c) weight > 1700 g. All participants had been referred for developmental stimulation by the medical staff. Experimental infants received reciprocal, multimodal (ATVV) stimulation paired with line singing of Brahms' Lullaby. Stimulation was provided for 15-30 minutes, one or two times per week from referral to discharge. Dependent variables were (a) days to discharge, (b) weight gain/day, and (c) experimental infants' tolerance for stimulation. Results showed that music and multimodal stimulation significantly benefited females' days to discharge and increased weight gain/day for both males and females. Both male and female infants' tolerance for stimulation showed marked and steady increase across the stimulation intervals with females' tolerance increasing more rapidly than males.

    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.

    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.

    The aim of the present study was to compare the effectiveness of different modes of mechanical ventilation in combination with secretolytic therapy with ambroxol in premature infants with respiratory distress syndrome. Seventy-three premature infants with hyaline membrane disease (HMD) (stage III–IV), also known as respiratory distress syndrome, who were supported by mechanical ventilation in the neonatal intensive care unit (NICU) of Xuzhou Central Hospital, were involved in the present study, between January 2013 and February 2015. Forty cases were randomly selected and treated with high frequency oscillatory ventilation (HFOV), forming the HFOV group, whereas 33 cases were selected and treated with conventional mechanical ventilation (CMV), forming the CMV group. Patients in the two groups were administered ambroxol intravenously at a dosage rate of 30 mg/kg body weight at the beginning of the study. The present study involved monitoring the blood gas index as well as changes in the respiratory function index in the two groups. Additionally, the incidence of complications in the premature infants in the two groups was observed prior to and following the ventilation. Pulmonary arterial oxygen tension (PaO2), the PaO2/fraction of inspired oxygen (FiO2) ratio, the oxygenation index [OI = 100 × mean airway pressure (MAP) × FiO2/PaO2], as well as the arterial/alveolar oxygen partial pressure ratio (a/APO2) = PaO2/(713 × FiO2 partial pressure of carbon dioxide (PaCO2)/0.8) of the patients in the HFOV group after 1, 12 and 24 h of treatment were significantly improved as compared to the patients of the CMV group. However, there was no significant difference between patients in the two groups with regard to the number of mortalities, complications such as pneumothorax, bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL), and the time of ventilation. In conclusion, combining HFOV

    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.

    We hypothesized that treatment of very low birth weight premature infants with r-HuEPO would increase erythrocyte incorporation and gastrointestinal absorption of iron. Infants with birth weights < or = 1.25 kg and gestational ages < 31 wk were randomized to receive 6 wk of 500 U of r-HuEPO/kg/wk (epo group, n = 7) or placebo (placebo group, n = 7). All infants received daily enteral supplementation with 6 mg of elemental iron per kg. An enteral test dose of a stable iron isotope, 58Fe, was administered after the 1st ("early dosing") and 4th ("late dosing") wk of treatment. Mean (+/-SD) erythrocyte incorporation of the dose of 58Fe administered determined 2 wk after early dosing was significantly greater in the epo group compared with the placebo group (4.4% +/- 1.6 versus 2.0 +/- 1.4%, p = 0.013). In contrast, after late 58Fe dosing, there was no difference between groups in incorporation (3.8 +/- 1.6% versus 5.5 +/- 2.7%). Within the epo group, percentage erythrocyte incorporation of 58Fe did not differ between early and late dosing, whereas in the placebo group it increased 3-fold (p < 0.01). Percentage absorption of 58Fe was not different between the epo and placebo groups after both early dosing (30 +/- 22% versus 34 +/- 8%) and late dosing (32 +/- 9% versus 31 +/- 6%). Absorption of nonlabeled elemental iron and 58Fe were significantly correlated with one another. The percentage of the absorbed 58Fe dose incorporated into Hb was not different between groups. We conclude that, although erythropoietin treatment stimulates erythrocyte iron incorporation in premature infants, it has no effect on iron absorption at the r-HuEPO dose studied.

    Objective To describe nurse behaviors that assisted parents to make life support decisions for an extremely premature infant before and after the infant’s birth. Design Qualitative, longitudinal, collective case study where interviews were done pre- and postnatally and medical chart data were collected. Setting Interviews were conducted face-to-face in a private room in the hospital, in the mother’s home, or over the telephone. Participants A sample of 40 cases (40 mothers, 14 fathers, 42 physicians, 17 obstetric nurses, 6 neonatal nurses, and 6 neonatal nurse practitioners) was recruited from three hospitals that provided high risk perinatal care. Parents were at least 18 years of age, English speaking, and had participated in a prenatal discussion with a physician regarding treatment decisions for their infant due to threatened preterm delivery. Physicians and nurses were those identified by parents who had spoken to them about life support treatment decisions for the infant. Methods Using a semi-structured interview guide, a total of 203 interviews were conducted (137 prenatal, 51 postnatal, and 15 end-of-life). For this analysis, all coded data related to the nurse’s role were analyzed and summarized. Results Parents and nurses both described several nurse behaviors: providing emotional support; giving information, and meeting the physical care needs of mothers, infants, and fathers. Physicians’ description of the nurse behaviors focused on the way nurses provided emotional support and gave information. Conclusions Nurses play a critical role in assisting parents surrounding life support decisions. PMID:20409115

    Purpose. To convey the need for a revised screening strategy for retinopathy of prematurity (ROP) for extremely low birth weight (ELBW) infants in China. Design. A retrospective longitudinal study. Methods. The medical charts of infants with a birth weight (BW) of less than 1 kg were reviewed. The infants were divided into three groups: group A, without ROP; group B, with ROP but not up to type 1 prethreshold or threshold ROP; group C, with type 1 prethreshold or threshold ROP. Data collected included gender, gestational age (GA), BW, postmenstrual age (PMA), age of onset of ROP, and age at which treatment was carried out, if required. Results. A total of 77 infants were involved. Fifty-six infants developed ROP at any stage and 38 infants developed type 1 prethreshold or threshold ROP. The mean BW and GA of infants in group A were significantly different compared with groups B and C. The mean PMA of onset of ROP in infants who developed mild ROP was 37 weeks compared with 34 weeks for infants who developed severe ROP. Conclusion. ELBW infants have a higher incidence of ROP in China which highlights the need for optimizing neonatal care for these infants. In ELBW infants, ROP tends to develop more severely when it occurs earlier. It is necessary for ELBW infants, especially for those with a BW less than 800 g or a GA less than 25 weeks, to be initially screened at an earlier time. PMID:28116141

    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

    The purpose of this study was to examine the relationship between maternal self-esteem and maternal attachment in mothers of hospitalized premature infants. The research instruments administered included: a demographic sheet, the Maternal Self-Report Inventory (MSRI), Rosenberg Self-Esteem Scale, and Leifer's How I Feel About My Baby Now Scale. Thirty-two mothers whose premature infants were medically stable and hospitalized in the NICU were studied. Two hypotheses on the positive relationships between maternal self-esteem and maternal attachment, and global self-esteem and maternal attachment could not be tested by correlational analyses due to the inadequate internal consistency of the How I Feel About My Baby Now Scale. A significant correlation was found between maternal self-esteem and global self-esteem. Thus, maternal role influenced general self-concept in mothers. In addition, it was found that there were no significant correlations between the MSRI and demographic variables, such as: maternal age, marital status, income, and educational level. Another result indicated that increased global self-esteem was correlated (p < .05) with maternal age, income, and educational level. The results of this study provide clinical nurses to pay attention not only to caregiving skills but also to the mother's appraisal of herself as a mother and attachment behaviors.

    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.

    2011-01-01

    Across Canada, the rate of preterm birth (i.e., at < 37 weeks' gestation) has been steadily increasing. Advances in perinatal medicine and neonatal intensive care have resulted in an increased capacity to intervene at the extremes of prematurity, leading to an increase in the overall survival of infants born at early gestations. There has been little corresponding decrease in long-term complications. As a result, additional stresses are placed on neonatal intensive care units across the country, impacting families, health care professionals, and society as a whole. Moral distress and moral residue are often cited in the neonatal-perinatal literature as stressors experienced by those who participate in the resuscitation decision-making process. They are directly related to the challenge of making a concrete decision about life and death at extremely early gestations in the context of long-term uncertainty. In this review, we performed a systematic search of medical and ethics literature pertaining to resuscitation at the extremes of prematurity. The perspective of health care professionals is explored, including how definitions of viability and parental perspectives contribute to the decision-making process. We argue for the necessity of further research exploring the inter-professional context of ethical decision making at the extremes of prematurity.

    Objective Neonatal intensive care units (NICU) around the world increasingly use music interventions. The most recent systematic review of randomized controlled trials (RCT) dates from 2009. Since then, 15 new RCTs have been published. We provide an updated systematic review on the possible benefits of music interventions on premature infants’ well-being. Methods We searched 13 electronic databases and 12 journals from their first available date until August 2016. Included were all RCTs published in English with at least 10 participants per group, including infants born prematurely and admitted to the NICU. Interventions were either recorded music interventions or live music therapy interventions. All control conditions were accepted as long as the effects of the music intervention could be analysed separately. A meta-analysis was not possible due to incompleteness and heterogeneity of the data. Results After removal of duplicates the searches retrieved 4893 citations, 20 of which fulfilled the inclusion/exclusion criteria. The 20 included studies encompassed 1128 participants receiving recorded or live music interventions in the NICU between 24 and 40 weeks gestational age. Twenty-six different outcomes were reported which we classified into three categories: physiological parameters; growth and feeding; behavioural state, relaxation outcomes and pain. Live music interventions were shown to improve sleep in three out of the four studies and heart rate in two out of the four studies. Recorded music improved heart rate in two out of six studies. Better feeding and sucking outcomes were reported in one study using live music and in two studies using recorded music. Conclusions Although music interventions show promising results in some studies, the variation in quality of the studies, age groups, outcome measures and timing of the interventions across the studies makes it difficult to draw strong conclusions on the effects of music in premature infants.

    Background: In recent years, there has been a rise in the number of premature births. Mothers of these newborns experience a high degree of stress over time. Since a more comprehensive understanding of this phenomenon can help the healthcare teams in detecting the deficiencies and needs of such newborns’ mothers for a better and more effective intervention, the present study was carried out to describe the mothers’ experiences in the area of premature birth. Materials and Methods: The present study is a qualitative study with a content analysis approach. The data collection process included 15 semi-structured and in-depth interviews with the mothers delivering premature babies during 2012-2013 in the medical educational centers of north and northwest of Iran. A purposive sampling method was used. All the interviews were recorded, typed, and finally analyzed using a qualitative content analysis with a conventional method. Results: Data analysis led to the extraction of continuous and multiple waves of emotional responses in mothers with premature birth. This has been revealed in mothers by the different categories of affective reactions, symptoms of anxiety, and mood disturbances including decline in performance, individual shortcomings, and mental irritation. Conclusions: Mothers’ unpreparedness and unexpected childbirth make them encounter the multiple and continuous waves of emotional responses, which will consequently lead to decline in performance, individual shortcomings, and mental irritation among them. Therefore, in order to prevent the negative and long-term consequences of such reactions, it is recommended that more attention should be given to support these mothers as the main caregivers of such infants.

    The effects of a double wall in a forced convection-heated incubator were studied on ten naked, nondistressed, premature infants by measuring their mean skin temperature, esophageal temperature, and oxygen consumption when they were in thermal steady state, with, and without, the double wall in place. The incubator air temperature was maintained within the recommended thermoneutral zone during the consecutive paired experiments. Ambient room temperature and relative humidity were constant and the infant's activity (quiet sleep) and postprandial state were the same in both conditions. Together with a significant rise in operative temperature (P less than .05) induced by the double wall (accounted for by a 0.9 C mean increased in incubator wall temperature nearest the baby), their mean skin temperature and esophageal temperatures increased (P less than .025), while a decrease in oxygen consumption occurred in nine of the ten infants (P less than .05). These findings suggest that the double wall reduced radiant and total heat loss from the baby by diminishing the temperature gradient between the skin and incubator surfaces and that metabolic heat production (oxygen consumption) was reduced when the double wall was in place.

    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

    Objectives To estimate the incidence of severe retinopathy of prematurity (ROP) requiring treatment and describe current treatment patterns in the UK. Design Nationwide population-based case ascertainment study via the British Ophthalmic Surveillance Unit and a national collaborative ROP special interest group. Practitioners completed a standardised case report form (CRF). Setting All paediatric ophthalmologists providing screening and/or treatment for retinopathy in the UK were invited to take part. Participants Any baby with ROP treated or referred for treatment between 1 December 2013 and 30 November 2014, treated with laser, cryotherapy, vascular endothelial growth factor (VEGF) inhibitor or vitrectomy/scleral buckling, or a combination. Main outcome measure Incidence of ROP requiring treatment. Results We received 370 CRFs; 327 were included. Denominator from epidemiological data: 8112 infants with birth weight of <1500 g. The incidence of ROP requiring treatment was 4% (327/8112, 95% CI 3.6% to 4.5%). Median gestational age was 25 weeks (IQR 24.3–26.1), and median birth weight 706 g (IQR 620–821). Median age at first treatment was 80 days (IQR 71–96). 204 right eyes (62.39%) had type 1 ROP, and 27 (8.26%) had aggressive posterior ROP. Infants were also treated for milder disease: 9 (2.75%) right eyes were treated for type 2 ROP, and 74 (22.63%) for disease milder than type 1 with plus or preplus, which we defined here as ‘type 2 plus’ disease. First-line treatment was diode laser photoablation of the avascular retina in 90.5% and injection of VEGF inhibitor in 8%. Conclusions ROP treatment incidence in the UK is 2.5 times higher than previously estimated. 8% of treated infants receive intravitreal VEGF inhibitor, currently unlicensed. Research is needed urgently to establish safety and efficacy of this approach. Earlier treatment and increasing numbers of surviving premature infants require an increase in appropriate eye care facilities and

    Forty-two infants, some premature, with enteropathogenic Esch. coli (EPEC) gastroenteritis were treated with an oral suspension of fosfomycin in a dose of 100 and 200 mg/kg per day. After the treatment there were 11 secondary clinical infections (6 reinfections and 5 relapses) which received a second treatment with fosfomycin. In total, 53 treatments were made with fosfomycin and in 92% of the cases there was both clinical and bacteriological cure. 93% of the EPEC strains were sensitive to fosfomycin in vitro, their minimum inhibitory concentrations being less than 64 mug/ml. The concentration of fosfomycin in blood and faeces was assayed by a diffusion plate microbiological method in a group of these children, showing that this antibiotic is partly absorbed and the rest eliminated in the faeces, where its concentration was found to be very high. Tolerance of the product was good, and there were neither toxic nor side effects. PMID:1103749

    We present a case of pure erythroleukemia, diagnosed at autopsy, in a dysmorphic premature infant who died of multiorgan failure within 24 hours of birth. Dysmorphic features included facial and limb abnormalities with long philtrum, microagnathia, downturned mouth, short neck as well as abnormal and missing nails, missing distal phalanx from the second toe, and overlapping toes. Internal findings included gross hepatomegaly and patchy hemorrhages in the liver, splenomegaly, and cardiomegaly; and subdural, intracerebral, and intraventricular hemorrhages. Histology revealed infiltration of bone marrow, kidney, heart, liver, adrenal, lung, spleen, pancreas, thyroid, testis, thymus, and placenta by pure erythroleukemia. Only 6 cases of congenital erythroleukemia have been previously reported with autopsy findings similar to those of this case. The dysmorphic features, although not fitting any specific syndrome, make this case unique. Congenital erythroleukemia and possible syndromes suggested by the dysmorphic features are discussed.

    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

    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 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

    Introduction: Hospitalization in neonatal intensive care unit may leads to many stresses for premature infants. Since premature infants cannot properly process stressors, identifying interventions that reduce the stress level for them is seems necessary. The aim of present study was to compare the effects of Field massage and Gentle Human Touch (GHT) techniques on the urine level of cortisol, as an indicator of stress in preterm infants. Methods: This randomized, controlled clinical trial was carried out in Al-Zahra hospital, Tabriz. A total of 84 premature infants were randomly assigned into three groups. First groups were touched by their mothers three times a day (15 minutes in each session) for 5 days by GHT technique. The second group was received 15 minutes Field massage with sunflower oil three times a day by their mothers for 5 days. The third group received routine care. In all groups, 24-hours urine samples were collected in the first and sixth day after the intervention and analyzed for cortisol level. Data were analyzed by SPSS software. Results: There were significant differences between mean of changes in cortisol level between GHT and control groups and Field massage and control groups (0.026). Conclusion: Although the massage with Field technique resulted in a significant reduction in blood cortisol level, but the GHT technique have also a similar effect. So, both methods are recommended for decreasing of stress in preterm infants. PMID:27752484

    Myelination is important perinatally and highly dependent on long-chain saturated and monounsaturated fatty acids. Long-chain polyunsaturated fatty acids, nowadays often supplemented, inhibit oleic acid synthesis. Using data from a premature cohort, we studied if nervonic, lignoceric and oleic acids correlated to growth and early development up to 18 months corrected age. Small for gestational age infants had lower concentrations than infants appropriate for gestational age. Only oleic acid was negatively correlated to long-chain polyunsaturated fatty acids. Oleic and lignoceric acids correlated to social interaction at one month, and nervonic acid to mental, psychomotor and behavioral development at 6, 10 and 18 months, also when adjusted for several confounders. Negative association between oleic acid and long-chain polyunsaturated fatty acids suggests inhibition of delta-9 desaturase, and nervonic acid´s divergent correlation to lignoceric and oleic acids suggests different metabolism in neonatal period. Our results may have implications for the supplementation of premature infants.

    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.

    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.

    2015-01-01

    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

    AIM To determine if packed red blood cell transfusions contribute to the development of parenteral nutrition associated liver disease. METHODS A retrospective chart review of 49 premature infants on parenteral nutrition for > 30 d who received packed red blood cell (PRBC) transfusions was performed. Parenteral nutrition associated liver disease was primarily defined by direct bilirubin (db) > 2.0 mg/dL. A high transfusion cohort was defined as receiving > 75 mL packed red blood cells (the median value). Kaplan-Meier plots estimated the median volume of packed red blood cells received in order to develop parenteral nutrition associated liver disease. RESULTS Parenteral nutritional associated liver disease (PNALD) was noted in 21 (43%) infants based on db. Among the 27 high transfusion infants, PNALD was present in 17 (64%) based on elevated direct bilirubin which was significantly greater than the low transfusion recipients. About 50% of the infants, who were transfused 101-125 mL packed red blood cells, developed PNALD based on elevation of direct bilirubin. All infants who were transfused more than 200 mL of packed red blood cells developed PNALD. Similar results were seen when using elevation of aspartate transaminase or alanine transaminase to define PNALD. CONCLUSION In this retrospective, pilot study there was a statistically significant correlation between the volume of PRBC transfusions received by premature infants and the development of PNALD.

    The initial microbiome impacts the health and future development of premature infants. Methodological limitations have led to gaps in our understanding of the habitat range and subpopulation complexity of founding strains, as well as how different body sites support microbial growth. Here, we used metagenomics to reconstruct genomes of strains that colonized the skin, mouth, and gut of two hospitalized premature infants during the first month of life. Seven bacterial populations, considered to be identical given whole-genome average nucleotide identity of >99.9%, colonized multiple body sites, yet none were shared between infants. Gut-associated Citrobacter koseri genomes harbored 47 polymorphic sites that we used to define 10 subpopulations, one of which appeared in the gut after 1 wk but did not spread to other body sites. Differential genome coverage was used to measure bacterial population replication rates in situ. In all cases where the same bacterial population was detected in multiple body sites, replication rates were faster in mouth and skin compared to the gut. The ability of identical strains to colonize multiple body sites underscores the habit flexibility of initial colonists, whereas differences in microbial replication rates between body sites suggest differences in host control and/or resource availability. Population genomic analyses revealed microdiversity within bacterial populations, implying initial inoculation by multiple individual cells with distinct genotypes. Overall, however, the overlap of strains across body sites implies that the premature infant microbiome can exhibit very low microbial diversity. PMID:28073918

    Most deaths of extremely premature infants occur in the perinatal period. Yet, little is known about how parents make life support decisions in such a short period of time. In the paper, how parents make life support decisions for extremely premature infants from the prenatal period through death from the perspectives of parents, nurses, and physicians is described. Five cases, comprised of five mothers, four neonatologists, three nurses, and one neonatal nurse practitioner, are drawn from a larger collective case study. Prenatal, postnatal and end-of-life interviews were conducted, and medical record data were obtained. In an analysis by two research team members, mothers were found to exhibit these characteristics: desire for and actual involvement in life support decisions, weighing pain, suffering and hope in decision making, and wanting everything done for their infants. All mothers received decision making help and support from partners and family, but relationships with providers were also important. Finally, external resources impacted parental decision making in several of the cases. By understanding what factors contribute to parents' decision making, providers may be better equipped to prepare and assist parents when making life support decisions for their extremely premature infants.

    Background: Progress in perinatal medicine has made it possible to increase the survival of very or extremely low birthweight infants. Developmental outcomes of surviving preterm infants have been analysed at the paediatric, neurological, cognitive, and behavioural levels, and a series of perinatal and environmental risk factors have been identified. The threat to the child's survival and invasive medical procedures can be very traumatic for the parents. Few empirical reports have considered post-traumatic stress reactions of the parents as a possible variable affecting a child's outcome. Some studies have described sleeping and eating problems as related to prematurity; these problems are especially critical for the parents. Objective: To examine the effects of post-traumatic reactions of the parents on sleeping and eating problems of the children. Design: Fifty families with a premature infant (25–33 gestation weeks) and a control group of 25 families with a full term infant participated in the study. Perinatal risks were evaluated during the hospital stay. Mothers and fathers were interviewed when their children were 18 months old about the child's problems and filled in a perinatal post-traumatic stress disorder questionnaire (PPQ). Results: The severity of the perinatal risks only partly predicts a child's problems. Independently of the perinatal risks, the intensity of the post-traumatic reactions of the parents is an important predictor of these problems. Conclusions: These findings suggest that the parental response to premature birth mediates the risks of later adverse outcomes. Preventive intervention should be promoted. PMID:12937044

    Retinopathy of prematurity (ROP), which develops due to abnormal retinal vascularization in premature babies, can lead to irreversible vision loss. B-scan ocular ultrasonography is a noninvasive examination which makes it possible to image the eye and orbit. Our purpose was to echographically assess the orbit of premature babies with and without retinopathy of prematurity (ROP), with a focus on the superior ophthalmic vein (SOV) which is normally not detected by orbital ultrasound. A prospective study design was used after approved by the local institutional review board. ROP was diagnosed by routine ophthalmoscopic exam. Orbital ultrasound was performed by a single experienced ophthalmologist and ultra-sonographer who was masked to the routine ROP screening results. The results of the ophthalmoscopic exam were compared to the orbital ultrasound findings. The study group was divided into those diagnosed with ROP and those not diagnosed with ROP and were found to be comparable by age and weight at the time of the US examination. The SOV was dilated in 21 of 22 eyes (95.4%) with ROP and in only 5 of 32 eyes (15.6%) without ROP. The present study suggests an association between ROP and dilatation of the SOV.

    Background: The rate of preterm births in Romania is one of the highest among European countries. However, there is little information regarding the ways in which premature birth affects the outcome in Romanian preterm infants. Aims: To investigate the effects of early developmental intervention after discharge from the hospital on motor and cognitive development in preterm infants. Study Design: Longitudinal observational study. Methods: We performed the Amiel-Tison neurologic evaluation at discharge and the Bayley Scales of Infant Development from 3 to 24 months. Based on these evaluations, an outcome score was formulated. Results: Between 2007 and 2010, 1157 of 2793 premature infants were included into the study. There was a negative correlation between the number of evaluations and the risk of developing neurologic sequelae (p<0.001). The correlation analysis demonstrated a significant association between the final category of risk at the end of the follow up program and the degree of compliance (p<0.01). At 24 months evaluation, there was a correlation between the low gestational age and the risk of developing severe neurologic sequelae (p<0.001). Conclusion: This study shows the importance of follow up program in decreasing the risk of developing neurologic sequelae in preterm infants. PMID:28251019

    The intestinal microbiome is a critical determinant of human health. Alterations in its composition have been correlated with chronic disorders, such as obesity and inflammatory bowel disease in adults, and may be associated with neonatal necrotizing enterocolitis in premature infants. Increasing evidence suggests that strain-level genomic variation may underpin distinct ecological trajectories within mixed populations, yet there have been few strain-resolved analyses of genotype–phenotype connections in the context of the human ecosystem. Here, we document strain-level genomic divergence during the first 3 wk of life within the fecal microbiota of an infant born at 28-wk gestation. We observed three compositional phases during colonization, and reconstructed and intensively curated population genomic datasets from the third phase. The relative abundance of two Citrobacter strains sharing ~99% nucleotide identity changed significantly over time within a community dominated by a nearly clonal Serratia population and harboring a lower abundance Enterococcus population and multiple plasmids and bacteriophage. Modeling of Citrobacter strain abundance suggests differences in growth rates and host colonization patterns. We identified genotypic variation potentially responsible for divergent strain ecologies, including hotspots of sequence variation in regulatory genes and intergenic regions, and in genes involved in transport, flagellar biosynthesis, substrate metabolism, and host colonization, as well as differences in the complements of these genes. Our results demonstrate that a community genomic approach can elucidate gut microbial colonization at the resolution required to discern medically relevant strain and species population dynamics, and hence improve our ability to diagnose and treat microbial community-mediated disorders.

    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.

    This article aims at summarizing normal EEG criteria and their maturational pattern in premature infants of 24 to 30 weeks gestational age. Although very premature infants with a normal outcome are not numerous, their normal EEG patterns must be known, as EEG constitutes a basis for neurological prognosis. Background activity is first discontinuous. Discontinuity decreases thereafter with increasing age, so that some long periods of continuous activity may be observed in active sleep, around 30 weeks of age. Conversely, interburst intervals become shorter and the proportion of time without EEG activity is decreasing. Based on EEG activity and eye movements, a rough sleep-state differentiation was described as soon as 25 weeks of gestational age and is completely achieved at 30 weeks. The main EEG figures are high-voltage delta waves of higher amplitude and slower frequency in younger infants. Temporal delta waves occur in sequences, these are very characteristic of the very premature infant; thereafter, they become smaller, less numerous and eventually disappear around 27-28 weeks. In contrast, occipital delta waves remain numerous and of high voltage, are usually bilateral and superimposed with fast rhythms. The two types of frontal delta waves that are observed in 24-27 weeks prematures disappear with maturation. Bursts of synchronized delta waves are less numerous than localized delta waves and also disappear before 28 weeks of age. Finally, diffuse theta bursts are mainly recorded at 26-27 weeks GA and become more localized in temporal areas with maturation. At 30 weeks, they are observed on temporal areas, mainly during slow-wave sleep.

    To study the effect of formula temperature on the thermogenic response to gavage feeding, we fed formula at room temperature (mean 24.0 degrees C, SD 1.1) and at body temperature (mean 36.9 degrees C, SD 1.7) to premature infants in a crossover design while monitoring their metabolic heat production and gastric, rectal, and skin temperatures. After feeding with room temperature formula, stomach temperature fell by 6.9 degrees C, rectal temperature by 0.2 degree C, and mean skin temperature by 0.6 degree C, and metabolic rate increased by 16% in the first postprandial hour. After body temperature feedings, mean skin temperature fell by 0.2 degree C, but stomach and rectal temperatures did not change appreciably. The metabolic rate rose by 12% in the first hour, which was not significantly less than the rise after room temperature feeding. The heat required to warm the formula to body temperature did not result in a detectably greater rise in metabolic rate after cool feeding than after warm feeding. The effects of feed temperatures below room temperature were not studied, but it remains possible that cooler feedings might produce even greater body cooling and a greater thermogenic response.

    Coordination between movements of individual tongue points, and between soft palate elevation and tongue movements, were examined in 12 prematurely born infants referred from hospital NICUs for videofluoroscopic swallow study (VFSS) due to poor oral feeding and suspicion of aspiration. Detailed post-evaluation kinematic analysis was conducted by digitizing images of a lateral view of digitally superimposed points on the tongue and soft palate. The primary measure of coordination was continuous relative phase of the time series created by movements of points on the tongue and soft palate over successive frames. Three points on the tongue (anterior, medial, and posterior) were organized around a stable in-phase pattern, with a phase lag that implied an anterior to posterior direction of motion. Coordination between a tongue point and a point on the soft palate during lowering and elevation was close to anti-phase at initiation of the pharyngeal swallow. These findings suggest that anti-phase coordination between tongue and soft palate may reflect the process by which the tongue is timed to pump liquid by moving it into an enclosed space, compressing it, and allowing it to leave by a specific route through the pharynx.

    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

    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.

    Introduction Scalp congenital hemangiomas (CHs) are rare vascular malformations among infants; they can be associated with an array of complications, including cardiac and cosmetic issues. Here, we report the endovascular treatment of a premature infant with a suspected large right parietal scalp hemangioma and associated high-output cardiac failure. Case description A two-day-old female premature infant (29 weeks gestational age; 1330 g birth weight) was referred by the neonatologists to our department for consultation and potential treatment of a large right parietal CH causing abrupt hypotension and high-output cardiac failure. Doppler ultrasound imaging at bedside revealed areas of arterial-venous shunting from the scalp and the presence of a superior sagittal sinus waveform, consistent with intracranial venous drainage. To alleviate cardiac dysfunction secondary to this lesion, trans-arterial embolization via n-butyl cyanoacrylate (nBCA) glue and deployment of detachable coils was performed via umbilical artery to occlude the right superficial temporal and occipital artery branches supplying the CH. Following treatment, the infant continued to require ventilator management, vasopressor support, and correction of coagulopathy, but by post-operative day two, her condition improved remarkably and the mass size began decreasing. The patient was discharged after a relatively uncomplicated subsequent 2½-month course in the neonatal intensive care unit. Conclusion Endovascular therapy proved effective and safe in treating cardiac failure associated with scalp CH, despite potential complications associated with neuro-interventional surgery in premature infants. Appropriate consideration in this patient population should be given to factors including blood loss, contrast use, radiation exposure, operative time, and possible intra-/post-operative complications.

    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.

    The objective of this study was to develop a population model of the pharmacokinetics (PK) of caffeine after orogastric or intravenous administration to extremely premature neonates with apnea of prematurity who were to undergo extubation from ventilation. Infants of gestational age <30 weeks were randomly allocated to receive maintenance caffeine citrate dosing of either 5 or 20 mg/kg/d. Four blood samples were drawn at prerandomized times from each infant during caffeine treatment. Serum caffeine was assayed by enzyme-multiplied immunoassay technique. Concentration data (431 samples, median: 4 per subject) were obtained from 110 (52 male) infants of mean birth weight of 1009 g, current mean weight (WT) of 992 g, mean gestational age of 27.6 weeks, and mean postnatal age (PNA) of 12 days. Of 1022 doses given, 145 were orogastric, permitting estimation of absolute bioavailability. A 1-compartment model with first-order absorption was fitted to the data in NONMEM. Patient characteristics were screened (P < 0.01) in nested models for pharmacokinetic influence. Model stability was assessed by nonparametric bootstrapping. Clearance (CL) increased nonlinearly with increasing PNA, whereas volume of distribution (Vd) increased linearly with WT, according to the following allometric models: CL (L/h) = 0.167 (WT/70) (PNA/12); Vd (L) = 58.7 (WT/70). The mean elimination half-life was 101. Interindividual variability (IIV) of CL and Vd was 18.8 % and 22.3 %, respectively. Interoccasion variability (IOV) of CL and Vd was 35.1% and 11.1%, respectively. This study established that the elimination of caffeine was severely depressed in extremely premature infants but increased nonlinearly after birth up to age 6 weeks. Caffeine was completely absorbed, which has favorable implications for switching between intravenous and orogastric routes. The interoccasion variability about CL was twice the interindividual variability, which, among other factors, indicates that routine serum

    The fetotoxic effects of angiotensin converting enzyme inhibitors when used during the second half of pregnancy are well known. The more recently developed angiotensin II receptor antagonists appear to yield similar fetal abnormalities. We report a premature infant born to a 41-year-old mother with a long history of infertility who had received losartan therapy for hypertension throughout an undetected pregnancy. Ultrasound examination 2 days prior to delivery identified a single fetus at 29 weeks gestation, anhydramnios, and an empty fetal bladder. The neonatal course was complicated by oliguria, hyperkalemia, marked renal dysfunction, respiratory failure, joint contractures, and a large anterior fontanelle with widely separated sutures. Hypotension (mean arterial pressure<25 torr) on day 1 responded to volume expansion, dopamine, and hydrocortisone. Serum creatinine reached a maximum of 2.7 mg/dL on day 6 and decreased to 0.4 by day 56. No formal urinalysis was performed, but the urine was reported to be visually clear throughout the course. Although a renal ultrasound on day 2 was normal, a follow-up study at 7 months revealed bilateral generalized parenchymal echogenicity, consistent with medical renal disease. Since then, weight and length have been at the 5th percentile or less, with apparent renal tubular acidosis necessitating the addition of sodium citrate supplements. This case emphasizes the importance of maintaining a high index of suspicion for potential pregnancy when contemplating the use of a drug of this class, and considering serial testing for pregnancy when using such drugs, even in patients with a longstanding history of infertility.

    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.

    Prematurity is the greatest single risk factor for death within the first year of life. The March of Dimes and Centers for Disease Control and Prevention define prematurity as birth before the completion of 37 weeks' gestation. In 2002, one in eight babies were delivered prematurely. This manuscript is Part I of a three-part series on premature infants. The overall goal of this series is to educate pediatric primary care providers regarding topics specific to delivering care to premature infants after discharge. Part I addresses the incidence of prematurity and the terminology used in neonatal literature and provides an overview of common comorbidities associated with prematurity. Part II will focus on the primary care management of uncomplicated premature infants. Part III will highlight issues of primary care for medically complex premature infants.

    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.

    The eyes of premature infants are especially vulnerable to injury after birth. A serious complication is called retinopathy of prematurity (ROP), which is abnormal growth of the blood vessels in an infant's eye. Retinopathy of prematurity develops when abnormal blood vessels grow and spread throughout the retina, which is the nerve tissue at the…

    IMPORTANCE Many premature infants are born without exposure to antenatal steroids (ANS) or with incomplete courses. This study evaluates the dose-dependent effect of ANS on rates of neonatal morbidities and early childhood neurodevelopmental outcomes of extremely premature infants. OBJECTIVE To compare rates of neonatal morbidities and 18- to 22-month neurodevelopmental outcomes of extremely premature infants exposed to no ANS or partial or complete courses of ANS. DESIGN, SETTING, AND PARTICIPANTS In this observational cohort study, participants were extremely premature infants (birth weight range, 401–1000 g; gestational age, 22–27 weeks) who were born at participating centers of the National Institute of Child Health and Human Development Neonatal Research Network between January 2006 and December 2011. Data were analyzed between October 2013 and May 2016. MAIN OUTCOMES AND MEASURES Rates of death or neurodevelopmental impairment at 18 to 22 months’ corrected age. Neurodevelopmental impairment was defined as the presence of any of the following: moderate to severe cerebral palsy, a cognitive score less than 85 on the Bayley Scales of Infant and Toddler Development III, blindness, or deafness. RESULTS There were 848 infants in the no ANS group, 1581 in the partial ANS group, and 3692 in the complete ANS group; the mean (SD) birth weights were 725 (169), 760 (173), and 753 (170) g, respectively, and the mean (SD) gestational ages were 24.5 (1.4), 24.9 (2), and 25.1 (1.1) weeks. Of 6121 eligible infants, 4284 (70.0%) survived to 18- to 22-month follow-up, and data were available for 3892 of 4284 infants (90.8%). Among the no, partial, and complete ANS groups, there were significant differences in the rates of mortality (43.1%, 29.6%, and 25.2%, respectively), severe intracranial hemorrhage among survivors (23.3%, 19.1%, and 11.7%), death or necrotizing enterocolitis (48.1%, 37.1%, and 32.5%), and death or bronchopulmonary dysplasia (74.9%, 68.9%, and 65

    Background: Proper sleep is essential for the development of premature infants. Infants, during hospitalization, might suffer from inappropriate postures and insufficient sleep hours. To compare the daily sleep quantities of premature infants in flexed (facilitated fetal tucking) posture and extended (free body) posture. This study is a randomized clinical trial which was conducted in neonatal ward of Al-Zahra Teaching Hospital of Tabriz, Iran, 2015. Thirty-two premature infants with the age range of 33–36 weeks were selected for the study. Materials and Methods: Every infant was studied for 4 days in a sequential format. Every infant was studied for 4 days and in a 12-h period every day (8 a.m–8 p.m). Each day, an infant was randomly put in one of the four statuses, namely, free body posture in the supine position, free body posture in the lateral position, facilitated fetal tucking in the supine position and facilitated fetal tucking in the lateral position. Films were recorded in the 12-h period (8 a.m–8 p.m). SPSS Software (version 13) was used for data analysis. Results: The results showed that about the main effect of posture on sleep variable, there was a statistically significant difference (P = 0.003). In addition, about the main effect of position on sleep variable; there was a statistically significant difference (P = 0.002). Meanwhile, there was no significant interaction effect between the posture and position for the daily sleep duration (P = 0.746). Daily sleep duration of the infants in flexed (facilitated fetal tucking) posture and lateral position is longer than that of the infants in extended (free body) posture and supine position. Conclusion: Daily sleep duration in the infants experiencing flexed posture and lateral position at rest is longer. Moreover, it decreases wakefulness time of the premature infants. PMID:28331510

    A 24-week premature infant developed severe right-sided pulmonary barotrauma secondary to mechanical ventilation for respiratory distress syndrome (RDS). High-frequency oscillatory ventilation and permissive hypercapnia were initiated. A chest tube was placed to relieve a pneumothorax, and a catheter was inserted into an air-filled cyst for drainage. These maneuvers failed to improve the child's respiratory status. The child's left main-stem bronchus was then successfully fiberoptically intubated for single-lung ventilation in order to reduce the unilateral barotrauma. Single-lung ventilation was effectively and safely continued for 5 days, with complete resolution of the pulmonary barotrauma.

    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.

    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.

    We examined the dosing regimens, compliance, and outcomes of premature infants who received palivizumab within the Canadian Registry of Palivizumab (CARESS). Infants receiving ≥1 dose of palivizumab during the 2006-2011 respiratory syncytial virus (RSV) seasons were recruited across 30 sites. Respiratory illness events were captured monthly. Infants ≤32 completed weeks gestational age (GA) (Group 1) were compared to 33-35 completed weeks GA infants (Group 2) following prophylaxis. In total, 6,654 patients were analyzed (Group 1, n = 5,183; Group 2, n = 1,471). The mean GA was 29.9 ± 2.9 versus 34.2 ± 2.2 weeks for Groups 1 and 2, respectively. Group differences were significant (all p-values <0.05) for the following: proportion of males, Caucasians, siblings, multiple births, maternal smoking, smoking during pregnancy, household smokers, >5 household individuals, birth weight, and enrolment age. Overall, infants received 92.6 % of expected injections. Group 1 received significantly more injections, but a greater proportion of Group 2 received injections within recommended intervals. The hospitalization rates were similar for Groups 1 and 2 for respiratory illness (4.7 % vs. 3.7 %, p = 0.1) and RSV (1.5 % vs. 1.4 %, p = 0.3). Neither the time to first respiratory illness [hazard ratio = 0.9, 95 % confidence interval (CI) 0.7-1.2, p = 0.5] nor to first RSV hospitalization (hazard ratio = 1.3, 95 % CI 0.8-2.2, p = 0.3) were different. Compliance with RSV prophylaxis is high. Despite the higher number of palivizumab doses in infants ≤32 completed weeks GA, the two groups' respiratory illness and RSV-positive hospitalization rates were similar.

    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.

    Background: In neonatal intensive care unit (NICU), neonatal sleep is disrupted due to different factors. Due to the critical role of sleep in premature infants’ brain development, this study aimed to investigate the effect of nesting and swaddling on the sleep duration of premature infants hospitalized in NICUs. Materials and Methods: In a crossover clinical trial, 42 preterm infants who met the inclusion criteria were enrolled. They were randomly assigned to two groups of nest-swaddle and swaddle-nest. Sleep status was evaluated by observation and use of Prechtl's criteria. Then, durations of total sleep time (TST) and quiet sleep time (QST) were recorded. Data were analyzed using repeated measure analysis of variance (ANOVA). Results: Mean values of TST and QST during nesting and also swaddling periods were significantly higher than in the control period in both groups (P < 0.001). Mean values of TST and QST in the swaddling period were higher than in the nesting period in both groups, However, these differences were not significant (P = 0.245). Conclusions: Both swaddling and nesting could significantly increase the duration of TST and QST, compared to the control. There were no significant differences between the effects of these interventions on TST and QST. Therefore, using any of these methods is suggested to improve infants’ quality of sleep in NICU, with respect to the ward policies. PMID:27904643

    Perinatal hypoxic-ischemic brain damage is a major cause of neuronal and behavior deficits, in which the onset of injury can be before, at or after birth, and the effects may be delayed. Pontosubicular neuron necrosis (PSN) is one of perinatal hypoxic-ischemic brain injury and its pathological peculiarity is neuronal apoptosis. In this study, we investigated whether apoptotic cascade of PSN used a caspase-pathway or not, and whether hypoglycemia activated apoptosis or not. Sections of the pons of PSN with and without hypoglycemia were stained using terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labeling (TUNEL) and immunohistochemistry for glial fibrillary acidic protein (GFAP), Bcl-2, Bcl-x and activated caspase 3. Additionally, we performed immunoblot analysis of Bcl-2, Bcl-x and activated caspase 3. TUNEL-positive cell was closely associated with the presence of karyorrhexis. Under combination of karyorrhectic and TUNEL-positive cells, number of apoptotic cells in premature brains was significantly more than in mature brains. Hypoxic-ischemic brain injury was considered to easily lead to apoptosis in premature infants. Moreover, as this pathophysiology, caspase-pathway activation contributed to neuronal death from caspase-immunoexpression analyses. PSN with hypoglycemia showed large number of apoptotic cells and higher expression of activated caspase 3. The result may be more severe with the background of hypoglycemia and prematurity complicated by hypoxia and/or ischemia.

  1. Oxygen as a cause of blindness in premature infants: "autopsy" of a decade of errors in clinical epidemiologic research.

    Several intellectual "autopsies" have recently reviewed errors in clinical epidemiologic studies of causation, such as the original claim that amyl nitrite "poppers" caused AIDS. The current autopsy was done to determine why it took more than a decade--1942 to 1954--to end an iatrogenic epidemic in which high-dose oxygen therapy led to retrolental fibroplasia (RLF) in premature infants, blinding about 10,000 of them. The autopsy revealed a museum of diverse intellectual pathology. When first noted, RLF was regarded as neither a new disease nor a postnatal effect. In early investigations, the ophthalmologists did not establish explicit criteria for diagnosis and confused RLF with malformations previously seen in full-term infants. Because the patients were not referred until months after birth, the ophthalmologists assumed that the lesion, which resembled an embryologic structure, must have occurred prenatally. Other events suggesting a prenatal cause for RLF were its strong statistical associations with fetal anomalies, multiple gestations, and maternal infections. Although these events were also associated with prematurity, it was ignored when the RLF cases were compared with controls who were mainly full-term infants. The postnatal timing of RLF was eventually recognized when investigators did cohort studies in premature infants and found that RLF could develop in eyes that were normal at birth. As the search for a cause turned to events occurring after birth, statistical associations were produced for agents such as light, vitamins, iron, vitamin E deficiency, and hypoadrenalism. Each study had its own methodologic flaws: controls were missing for light; co-maneuvers were ignored for vitamins and iron; objective diagnosis was not used for vitamin E deficiency; and the research on hypoadrenalism contained biases in susceptibility and detection as well as problems of a competing outcome event. When the role of oxygen administration was first considered, the

    Severe premature babies present a risk profile higher than the normal population. Reasons are related to the incomplete development of physiological systems that support baby's life. Heart Rate Variability (HRV) analysis can help the identification of distress conditions as it is sensitive to Autonomic Nervous System (ANS) behavior. This paper presents results obtained in 35 babies with severe prematurity, in quiet and active sleep and in prone and supine position. HRV was analyzed in time and frequency domain and with nonlinear parameters. The novelty of this approach lies in the combined use of parameters generally adopted in fetal monitoring and "adult" indices. Results show that most parameters succeed in classifying different experimental conditions. This is very promising as our final objective is to identify a set of parameters that could be the basis for a risk classifier to improve the care path of premature population.

    Infants who are dependent on parenteral nutrition (PN) sometimes develop PN-associated cholestasis (PNAC). A compassionate use protocol, approved by the U.S. Food and Drug Administration and the institutional review board, guided enrollment of hospitalized infants with PNAC (<1 year of age, PN dependence for >3 weeks). Plasma concentrations of essential fatty acids were monitored before and after a soybean-based PN lipid, infused at 3 g/kg body weight/d, was replaced by an experimental fish oil-based intravenous fat emulsion (FO-IVFE) at 1.0 g/kg/d. All participants were born premature (n = 10; 20% male). At enrollment, infants were (mean ± SD) 86.5 ± 53.5 days of life and weighed 2.24 ± 0.87 kg; direct bilirubin was 5.5 ± 1.3 mg/dL. After treatment, blood concentrations significantly increased from baseline (P < .017) for circulating eicosapentaenoic acid (6.3 ± 3.0 to 147.8 ± 53.1 µg/mL), docosahexaenoic acid (20.7 ± 6.5 to 163.7 ± 43.4 µg/mL), pristanic acid (0.01 ± 0.01 to 0.17 ± 0.03 µg/mL), and phytanic acid (0.06 ± 0.03 to 0.64 ± 0.15 µg/mL). In contrast, total plasma ω-6 fatty acids (including linoleic acid) decreased (P < .017). The triene/tetraene ratio remained below the threshold value of 0.2 that defines ω-6 deficiency. No adverse effects were observed attributable to FO-IVFE. Discontinuation of FO-IVFE was typically due to infants (body weight 3.76 ± 1.68 kg) transitioning to enteral feeding rather than for resolution of hyperbilirubinemia (direct bilirubin 7.9 ± 4.8 mg/dL). These exploratory results suggest that FO-IVFE raises circulating ω-3 fatty acids in premature infants without development of ω-6 deficiency in the 8.3 ± 5.8-week time frame of this study.

    The effect of heparin dose and infusion rate on plasma lipids, lipases, and unbound bilirubin was investigated in 22 premature infants with physiologic jaundice. Infants were randomly assigned to receive low or high intravenous doses (24 vs 137.3 U/day) of heparin. Each patient then received 2 g/kg/day of 10% Intralipid on 2 successive days: one day during a 15-hour period and the other day over 24 hours, with the order assigned randomly. The results demonstrate a significantly greater change in serum-free fatty acids in infants receiving the high heparin dose during the 15-hour lipid infusion period. Lipoprotein lipase activity rose more with the high heparin dose and equally at either infusion rate. We conclude that lipid infusions of 2 g/kg/day with low heparin dosage infused over 24 hours resulted in less elevation in serum-free fatty acids. There were no adverse effects on unbound bilirubin at either infusion rate or heparin dosage.

    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

    PubMed

    Sinner, B; Becke, K; Engelhard, K

    2013-02-01

    Many animal experiments have shown that anesthetics can have a neurotoxic effect on immature brains because they induce apoptosis and influence neurogenesis and synaptogenesis. In animal experiments this has substantial implications for the neurocognitive functions of animals in later life. Whether these results of animal experiments can be transferred to humans is currently the subject of intensive research. In several retrospective studies no clear association between anesthesia in premature babies, newborns or infants and the occurrence of learning disorders or behavioral problems could be found. The prospective studies GAS and PANDA are designed to obtain a deeper insight and if possible to clarify this problem. Because of the high relevance of this topic and in order to achieve more clarity for this problem when dealing with parents, the scientific working group for neuroanesthesia and pediatric anesthesia of the German Society for Anesthesiology and Intensive Care Medicine (DGAI) has formulated a position document on the basis of currently available data.

    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.

    Temporary tracheal balloons have been shown to improve lung growth in fetuses with severe congenital diaphragmatic hernia. Fetoscopic Endoluminal Tracheal Occlusion (FETO) is performed at 26-28 weeks gestation, and then is removed in utero at 34 weeks gestation at highly specialized centers. In case of preterm labor at a hospital without a specialized team, a number of techniques have been used to remove the balloon, sometimes with death of the newborn. We have successfully performed an ultrasound-guided approach to puncture and remove the tracheal balloon in a premature infant in an emergency setting at birth. After that she was treated for congenital diaphragmatic hernia at our Newborn Intensive Care Unit.

    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.

    Retinopathy of prematurity (ROP) has been a major problematic disorder during childhood. Laser photocoagulation (LPC) has been proven to be effective in most of the ROP cases. Adenoviral conjunctivitis (AVC) is responsible for epidemics among adult and pediatric population. It has also been reported to be a cause of outbreaks in neonatal intensive care units (NICU) several times. We herein demonstrate a case with AVC who underwent LPC for ROP. And we discuss the treatment methodology in such cases. PMID:25874149

    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.

    Preterm premature rupture of the membranes (pPROM) is responsible for approximately one third of the over 450,000 preterm births occurring in the United States annually. In this manuscript, we summarize the outcomes and analyses related to the National Institute of Child Health and Human Development Maternal Fetal Medicine Units Network (NICHD-MFMU) network multicenter trial of antibiotics to reduce infant morbidity after pPROM. Based on evident reduction in gestational age dependent and infectious infant morbidity, we provide the rationale for aggressive intravenous and oral, broad spectrum Ampicillin/Amoxicillin, and Erythromycin therapy during conservative management of pPROM before 32 weeks' gestation. We further review the histopathologic correlates to pPROM, to antibiotic treatment, and to perinatal outcome, and discuss the relationships between maternal and neonatal cytokine levels intercellular adhesion molecule, and other clinical and plasma markers regarding perinatal morbidity. The use and limitations of ultrasound and vaginally collected amniotic fluid pulmonary maturity assessment are discussed.

    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.

    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.

    The question to be answered was: Does premature rupture of membranes (PROM) and duration of PROM lead to increased mortality, neonatal and late morbidity and adverse cognitive developmental outcome? We present data of a bi-national cohort observation study in South Bavaria (SBy) and South Finland (SF). The sample included all children, who were admitted to a children's hospital (SBy N: 7505/70,600 live births; SF N: 1536/15,618), and some not transferred control infants (916 and 658, respectively). Obstetric details like PROM were obtained from perinatal records. Mortality and neonatal morbidity were recorded prospectively. Somatic, neurological and cognitive development was assessed at five and 20 months (corrected age), and final diagnosis of cerebral palsy (CP) and severe mental retardation was made at 56 months of age. Data were analysed separately for three gestational groups (< 32 (I), 32-36 (II), and > 36 weeks PMA (III)). PROM occurred more frequent in SBy than in SF and in both areas with preterm delivery. PROM irrespective of its duration had no adverse effect on mortality, morbidity, CP-rate or cognitive outcome of groups I and III in either SBy or SF. There was even a slightly lower mortality rate in extremely preterm infants after PROM. In SBy only, group II with PROM > 24 hours had a slightly increased incidence of CP. Unfavorable outcome was closely related to perinatal infections, which increased with duration of PROM. PROM and/or preterm labor occurred more often without than with inflammations of amnion and placenta. We conclude: PROM per se has no adverse effects on longterm outcome of special care infants, but it is closely associated with the developmental risk factors perinatal infections and, in particular, preterm birth. The prevention of ascending infections deserves further investigation, although such action may be beneficial lately to only a minority of individuals.

    Background Patent ductus arteriosus (PDA) is a common cause of morbidity. The aim of this study was to compare the efficacy of oral Acetaminophen and oral Ibuprofen for the closure of patent ductus arteriosus (PDA) in preterm infants. Objectives This study demonstrated that, there was no significant difference between treatment of PDA with either oral Acetaminophen or oral Ibuprofen in preterm neonates. Patients and Methods This clinical trial, randomized study, enrolled 120 infants, with a gestational age of < 37 weeks, who were admitted in neonatal intensive care unit of Afzalipour hospital, Kerman, Iran, in 2014. PDA was confirmed echocardiographically. The trial was registered in Iranian registry of clinical trials (Reg. No. 25542). Sixty-seven infants received oral Acetaminophen (15mg/kg every six hours for three days) and 62 infants received Ibuprofen (an initial dose of 20 mg/kg, followed by 10 mg/kg at 24 and 48 hours). To evaluate the efficacy of the treatment, a second echocardiography was done after completing the treatment. Results After the first course of the treatment, PDA closed in 55 (82.1 %) patients who received oral Acetaminophen vs. 47 (75.8 %) of those given oral Ibuprofen (P = 0.38). After the second course of treatment, PDA closed in 50 % of oral Acetaminophen group and 73.3% of oral Ibuprofen group (P = 0.21). Conclusions This study demonstrated that, there was no significant difference between treatment of PDA with either oral Acetaminophen or oral Ibuprofen in preterm neonates. Oral Ibuprofen can effectively close PDA but is unfortunately associated with some adverse effects limiting its utility thus we studied an alternative drug with similar efficacy and less adverse effects. This study has recommends Acetaminophen with minimal complications for the treatment of PDA in preterm neonates instead of Ibuprofen. PMID:27713809

    Objective: To investigate the role of interleukin-6 (IL-6) and C-reactive protein (CRP) in non-thyroidal illness (NTI) in premature infants. Methods: Serum levels of IL-6 and CRP, thyroid-stimulating hormone (TSH), total thyroxine (T4), free T4 (fT4), total triiodothyronine (T3), and free T3 (fT3) were determined at the 1st, 2nd and 4th weeks of postnatal life in 148 premature infants born before 33 weeks of gestation. Results: At the 1st week, serum T3 was negatively correlated with IL-6(r= -0.33, p= 0.001) and CRP (r= -0.17, p= 0.03). Serum T3 was negatively and more strongly correlated with IL-6 (r= -0.49, p= 0.001) and CRP (r=- 0.33,p= 0.03) at the 2nd week, at which time sepsis frequency and low T3 rates were the highest. At the 4th week, mortality rate was higher among infants with lower T3 levels. Conclusions: High IL-6 and CRP values related to neonatal sepsis might have a significant role in the pathogenesis of NTI in premature infants. Conflict of interest:None declared. PMID:22672862

    As many as 118 premature neonates weighing from 900 to 2500 g at birth, afflicted with hyperbilirubinemia were examined. In 80 children, the use of phototherapy (PT) appeared an indispensable condition of the treatment of jaundice. The regimen of radiation varied: 28 children received intermittent treatment lasting 24 hours; 52 children were given continuous treatment, with the period of radiation amounting to 48 or 72 hours. Part of the children were on PT combined with alpha-tocopherol acetate. Bilirubin concentration in the blood serum, lipid peroxidation, the lipid and phospholipid spectra of red blood cell membranes were used as criteria for the treatment efficacy. The highest therapeutic effect was attained in the children who received continuous radiation lasting 48 hours. The efficacy of PT turned out enhanced on its combination with alpha-tocopherol acetate.

    Preterm infants (PIs) often require respiratory support due to surfactant deficiency. 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

  7. 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.

    Effects of oral L-carnitine supplementation on fat and protein metabolism have been studied in 20 low-birth-weight premature infants (mean weight at birth 1.519 g, range 1,200-1,880 g) fed with pooled pasteurized human milk. Throughout 7 consecutive days, started at various postnatal ages (range 10-33 days) infants were fed exclusively with milk containing 300 nmol/ml L-carnitine as added supplement. The amount of extra carnitine intake ranged from 42.6 to 72.0 mumol/kg/day. Until day 5 of supplementation there was a continuous increase in the daily urinary excretion of total carnitine, which levelled off thereafter, corresponding approximately to 50% of the extra L-carnitine intake, indicating that a part of the supplement was retained by the body. Total, free and esterified carnitine levels were significantly elevated in the plasma at the end of the study period. The increased levels of acylcarnitines in plasma and urine indicate that the carnitine supplement was taken up by tissues and entered the intermediary metabolism. Plasma triglyceride level was decreased, whereas 3-hydroxybutyrate level was increased at the end of supplementation, indicating an enhanced fat utilization. Plasma and urine analysis also revealed an altered nitrogen handling. There was a marked decrease in plasma urea level as well as a significant fall in the urea and total N excretion, with a trend of decrease in excretion of 3-methylhistidine, suggesting a reduced amino acid and protein catabolism during L-carnitine supplementation.

    The earliest signs of Retinopathy of Prematurity (ROP) are tortuosity and dilation of retinal vessels. Such vascular changes are considered of primary importance for the diagnosis and the follow-up of the disease. However, a widely accepted computerized system for their quantitative measurement is still missing. Images taken from a preterm baby's eye are often low-contrast, noisy, and blurred. Algorithms that have been successfully applied to analyze adult retinal images do not work well in ROP images. We propose here a novel method for the automatic extraction of vessel centerline in wide-field ROP retinal images, based on a sparse tracking scheme. After a set of seed points is identified all over the image, vessels are traced by connecting those seeds by means of minimum cost paths, whose weights depend on similarity features and alignment evaluated by a custom line operator. The performance of the method was assessed on a dataset of 20 images acquired with the RetCam fundus camera. A sensitivity of 0.78 and a false detection rate of 0.15 were obtained with respect to manual ground truth reference.

    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

    The development of cerebral cortex includes highly organized, elaborate and long-lasting series of events, which do not come to an end by the time of birth. Indeed, many developmental events continue after the 40th postconceptual week resulting in a long morphological, behavioral and cognitive development of children. Premature birth causes an untimely dramatic change in the environment of the human fetus and often results in serious threats for life. Cognitive abilities of prematurely born children vary, but a correlation between cognitive impairment and the time of birth is evident. In this study we review the morphological evidence of cortical maturation in preterm and full-term infants. Various aspects of postnatal cortical development including cell proliferation and maturation of neurons in the temporal archi- and neocortex are discussed and compared in preterm infants and age-matched full-term controls. Our results suggest that cell proliferation and maturation are not influenced by the preterm delivery. In contrast, the perinatal decrease of the number of Cajal-Retzius cells might be regulated by a mechanism that is affected by preterm birth. We demonstrate that cognitive deficiencies of the prematurely born infants cannot be explained with light microscopically observed alteration of proliferation and maturation of neurons.

    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

    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.

    The impact of a premature birth can be very traumatic for parents. They are usually not prepared for this event, and their sense of grief and loss is so intense that they often have difficulty coping with the situation. A parent group can help parents adapt to the crisis of prematurity by providing information and family support. This article describes the development of a parent group at a regional perinatal center in Ontario and identifies key factors for its successful initiation and maintenance.

    The aim of this article is to generate knowledge about parents' participation in life-and-death decisions concerning their very premature and/or critically ill infants in hospital neonatal units. The question is: what are parents' attitudes towards their involvement in such decision making? A descriptive study design using in-depth interviews was chosen. During the period 1997-2000, 20 qualitative interviews with 35 parents of 26 children were carried out. Ten of the infants died; 16 were alive at the time of the interview. The comparative method (grounded theory) was used to analyse the data. The analysis was carried out continuously and in parallel with data collection. Six categories were revealed by the analysis: indecision and uncertainty (ambivalence); information and communication; participate, but do not decide; seeming to be included; the parents' child; and individual consideration. The findings appear to indicate that parents agree that they should not have the final word in decisions concerning their infants' future life or death. Such a responsibility would put too heavy a burden on parents who lack the medical knowledge and the professional experience needed to make such a decision, and would be likely to lead to them experiencing strong feelings of guilt. The findings show that parents should be well informed and listened to during the whole decision-making process. Their primary concern was how nurses and physicians communicate with parents who are experiencing a crisis, and how this serious information is presented.

    A system of instrumentation for the continuous measurement of the respiratory gases during assisted ventilation of neonates and premature infants based upon "breath-by-breath-method" is described. The four respiratory parameters flow (V), ventilation pressure (p), oxygen-concentration and carbon dioxide-concentration are measured. These datas are processed by a computer to generate a continuous display of the respiratory minute volume, the tidal volume, the breath rate, the oxygen consumption and the carbon dioxide production. All parameters are stored and can be displayed or plotted as trends. The flow-measurement is performed using hot-wire-anemometry. The very small flow sensor is adapted directly to the tube. Next to this sensor, the respiratory gas for the analysis of the O2- and CO2- concentration is suctioned off continuously. First clinical experience in mechanically ventilated newborns is characterized.

    Urinary neutrophil gelatinase-associated lipocalin (uNGAL) is produced in response to tubular epithelial injury and is a biomarker of tubulointerstitial injury. The aim of the present study was to examine whether acute kidney injury (AKI) could be predicted by measuring uNGAL in very low-birth weight (VLBW) infants. Forty VLBW infants with birthweight below 1,500 g were enrolled in the present study. uNGAL and serum creatinine (sCre) were measured daily from postnatal days 0 to 8. Infants with sCre ≥1.2 mg/dl were diagnosed with AKI. The relationship of uNGAL with sCre was measured on the day after uNGAL measurement (next-day sCre) was examined. The results showed that 16 infants had sCre ≥1.2 mg/dl in this period. Logistic regression analysis revealed that uNGAL on postnatal days 2, 3, 4, 5 and 6 was correlated with next-day sCre (P<0.05). uNGAL corrected by urinary Cre (uCre) (uNGAL/uCre) was only correlated with an increase in next-day sCre on postnatal days 5 and 6 (P<0.05). For the logistic analysis, subjects with high and low uNGAL levels based on the median value for each day, uNGAL on postnatal days 2, 3 and 6 in the high uNGAL group was correlated with an increase in next-day sCre. Thus, AKI may be predicted by measuring uNGAL in VLBW infants. This measurement was non-invasive, and is potentially useful for the evaluation of renal function in VLBW infants. PMID:28105101

    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

    Background This study aimed to identify the main risk factors for development of retinopathy of prematurity (ROP) in neonatal intensive care units in Alexandria, Egypt, from January 2010 to January 2012. Methods A prospective cohort study was undertaken in infants weighing < 1250 g and maternal postmenstrual age < 32 weeks if there was concern about prolonged exposure to oxygen. The main clinical outcomes were occurrence of any stage of ROP and in particular severe ROP. Perinatal variables considered were: birth weight, gestational age, gender, method of ventilation (nasal continuous airway pressure or intermittent mechanical ventilation), packed red blood cell and/or plasma transfusion, occurrence of sepsis, neonatal indirect hyperbilirubinemia, intraventricular hemorrhage, and patent ductus arteriosus. After obtaining informed consent from the parents, infants at risk were examined for ROP using indirect ophthalmoscopy, ie, RetCam II fundus photography. Results The study included 152 infants of mean gestational age 31.02 weeks and mean birth weight 1.229 kg. Seventy-two cases (47.5%) were male and 80 cases (52.5%) were female. Of the cases screened, 100 (65.6%) had no ROP, 52 had ROP of any stage (34.4%), and 27 (18%) had stage 1, five (3.3%) had stage 2, 17 (11.5%) had stage 3, and three (1.6%) had stage 4 disease. No infants had stage 5 ROP. Of all our cases with ROP, 15 (28.6%) had prethreshold disease type 1 that required treatment, comprising 9.8% of all cases screened for ROP. Using stepwise logistic regression analysis, all risk factors studied were found to be significantly associated with the development of ROP, except for neonatal indirect hyperbilirubinemia. Severity of ROP was inversely proportional to birth weight and gestational age. Conclusion ROP occurred in 34.4% of all infants screened in the neonatal intensive care units at three obstetric hospitals in Alexandria.

    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.

    The purpose of this study was to examine different protocols with regard to the presentation of music stimuli and compare gender differential reactions to those stimuli. Subjects for this study (N = 63) were premature infants in the Neonatal Intensive Care Unit (NICU) between the gestational ages of 28 and 33 weeks. Half of the experimental infants listened to 20 mins of lullaby music (female voice with orchestral background) on 2 days followed by 20 mins of classical music (Mozart string music) on 2 days. The other half listened to the same music in the reverse order. One quarter of the males and one quarter of the females listened to music presented at an average of 65 dB, one quarter at an average of 70 dB, one quarter at an average of 75 dB, and one quarter did not listen to any music and served as control subjects. Head circumference data were collected four times by the researcher: (a) upon receipt of parental consent, (b) on the first day of music presentation (1 week after consent), (c) on the last day of music presentation, and (d) 1 week after music presentation. Physiological data (heart rate, respiratory rate, oxygen saturation) were recorded by the researcher at 2-minute intervals starting 4 minutes prior to and ending 4 minutes after music presentation. There was a significant difference (p < .0001) in average daily head growth across time, but this seems unrelated to the music condition as the same curvilinear trend (larger gain during days of treatment, smaller gain during baseline before and after treatment) was noted for control infants who did not listen to music. Results indicate a significant (p = .002), but biologically unimportant, decrease in heart rate over the course of data collection. No differences due to gender were noted.

  7. How I transfuse red blood cells and platelets to infants with the anemia and thrombocytopenia of prematurity

    2010-01-01

    Many aspects of hematopoiesis are either incompletely developed in preterm infants or still functioning to serve the fetus (i.e., the intrauterine counterpart to a liveborn preterm neonate). This delayed development and/or slow adaptation to extrauterine life diminishes the capacity of the neonate to produce red blood cells (RBCs), platelets (PLTs), and neutrophils—particularly during the stress of life-threatening illnesses encountered after preterm birth such as sepsis, severe pulmonary dysfunction, necrotizing enterocolitis, and immune cytopenias. The serious medical and/or surgical problems of preterm birth can be further complicated by phlebotomy blood losses, bleeding, hemolysis, and consumptive coagulopathy. To illustrate, some preterm infants, especially those with birth weight less than 1.0 kg and respiratory distress, are given numerous RBC transfusions early in life owing to several interacting factors. Neonates delivered before 28 weeks of gestation (birth weight, <1.0 kg) are born before the bulk of iron transport has occurred from mother to fetus via the placenta and before the onset of marked erythropoietic activity of fetal marrow during the third trimester. Soon after preterm birth, severe respiratory disease can lead to repeated blood sampling for laboratory studies and, consequently, to replacement RBC transfusions. Additionally, preterm infants are unable to mount an effective erythropoietin (EPO) response to decreasing numbers of RBCs, and this factor contributes to the diminished ability to compensate for anemia—thus enhancing need for RBC transfusions.

    Tortuosity and dilation of retinal vessels are considered of primary importance for the diagnosis and follow-up of the Retinopathy of Prematurity (ROP) disease. We developed an algorithm to estimate vessel tortuosity in images acquired with a wide-field fundus camera in ROP subjects, offering clinicians a quantitative, objective, and reproducible diagnostic parameter. Vessels were manually traced in 20 images to provide error-free input data for the tortuosity estimation. At first we investigated different vessel-level measures, some including also caliber information. Then we used them to obtain different imagelevel tortuosity measures, which were eventually combined in a supervised approach to provide a tortuosity index capable to reproduce the clinical experts assessment.To provide manual assessment, the 20 images were independently ordered by increasing tortuosity by three clinical graders and three retinal imaging experts. The proposed tortuosity index obtains a Spearman’s correlation coefficient of 0.95 with ground truth, a performance comparable to the clinical graders’ one and better than the retinal imaging experts’ one.

    Purpose To evaluate the serial changes in retinal vasculature in infants treated with intravitreal bevacizumab (IVB) for aggressive posterior retinopathy of prematurity (APROP) in zone I. Methods Retrospective analysis of serial changes in retinal vasculature after IVB in the seven eyes of four babies with APROP in zone I. Results The 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. Conclusions The 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.

    Traditional birth attendants (TBAs) can be invaluable in assisting to dispel myths commonly associated with natal/neonatal teeth. To ensure correct delivery of the message, baseline data of their beliefs is important. To assess the attitude and beliefs of some Nigerian TBAs to prematurely erupted teeth in infants, a total enumeration of the TBAs in the five urban Local Government Areas in Ibadan was conducted and 163 consenting TBAs were recruited using an interviewer-administered questionnaire. The attitude of the TBAs was that of fear and shock (35.6%) while 30 (18.4%) will consider the child weird. Perceived causes of the variation include evil spirits (31.9%), contravening cultural taboos (9.2%), and prolonged gestation (4.9%). Beliefs on the effect of natal/neonatal teeth on the child include strange behavior (31.3%), child developing evil spiritual powers (41.1%), and mental retardation (3.1%). Practices included advising parents to get rid of/or hide the child (4.9%) and immediate extraction of the teeth with/without sacrifices (35.6%). There is an urgent need to address knowledge gaps by giving health education to TBAs.

  11. Prematurity Affects Age of Presentation of Pyloric Stenosis.

    2017-02-01

    Term infants with hypertrophic pyloric stenosis (HPS) typically present between 4 and 6 weeks. There is limited consensus, however, regarding age of presentation of premature infants. We aim to determine if there is an association between the degree of prematurity and chronological age of presentation of HPS. A total of 2988 infants who had undergone a pyloromyotomy for HPS were identified from the 2012 and 2013 NSQIP-P Participant Use Files. Two hundred seventeen infants (7.3%) were born prematurely. A greater degree of prematurity was associated with an older chronological age of presentation ( P < .0001). Prematurity was significantly associated with an increase in overall postoperative morbidity, reintubation, readmission, and postoperative length of stay. When clinicians evaluate an infant with nonbilious emesis with a history of prematurity, they should consider pyloric stenosis if the calculated postconceptional age is between 44 and 50 weeks. When counseling families of premature infants, surgeons should discuss the increased incidence of postpyloromyotomy morbidity.

    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.

    Temporal theta slow-wave activity (TTA-SW) in premature infants is a specific signature of the early development of temporal networks, as it is observed at the turning point between non-sensory driven spontaneous local processing and cortical network functioning. The role in development and the precise location of TTA-SW remain unknown. Previous studies have demonstrated that preterms from 28 weeks of gestational age (wGA) are able to discriminate phonemes and voice, supporting the idea of a prior genetic structural or activity-dependent fingerprint that would prepare the auditory network to compute auditory information at the onset of thalamocortical connectivity. They recorded TTA-SW in 26-32 wGA preterms. The rate of TTA-SW in response to click stimuli was evaluated using low-density EEG in 30 preterms. The sources of TTA-SW were localized by high-density EEG using different tissues conductivities, head models and mathematical models. They observed that TTA-SW is not sensory driven. Regardless of age, conductivities, head models and mathematical models, sources of TTA-SW were located adjacent to auditory and temporal junction areas. These sources become situated closer to the surface during development. TTA-SW corresponds to spontaneous transient endogenous activities independent of sensory information at this period which might participate in the implementation of auditory, language, memory, attention and or social cognition convergent and does not simply represent a general interaction between the subplate and the cortical plate.

    We mapped and characterized changes in the activity of brainstem cell groups under hypoxia in one-day-old newborn mice, an animal model in which the central nervous system at birth is particularly immature. The classical biphasic respiratory response characterized by transient hyperventilation, followed by severe ventilation decline, was associated with increased c-FOS immunoreactivity in brainstem cell groups: the nucleus of the solitary tract, ventral reticular nucleus of the medulla, retrotrapezoid/parafacial region, parapyramidal group, raphe magnus nucleus, lateral, and medial parabrachial nucleus, and dorsal subcoeruleus nucleus. In contrast, the hypoglossal nucleus displayed decreased c-FOS immunoreactivity. There were fewer or no activated catecholaminergic cells activated in the medulla oblongata, whereas ~45% of the c-FOS-positive cells in the dorsal subcoeruleus were co-labeled. Approximately 30% of the c-FOS-positive cells in the parapyramidal group were serotoninergic, whereas only a small portion were labeled for serotonin in the raphe magnus nucleus. None of the c-FOS-positive cells in the retrotrapezoid/parafacial region were co-labeled for PHOX2B. Thus, the hypoxia-activated brainstem neuronal network of one-day-old mice is characterized by (i) the activation of catecholaminergic cells of the dorsal subcoeruleus nucleus, a structure implicated in the strong depressive pontine influence previously reported in the fetus but not in newborns, (ii) the weak activation of catecholaminergic cells of the ventral reticular nucleus of the medulla, an area involved in hypoxic hyperventilation, and (iii) the absence of PHOX2B-positive cells activated in the retrotrapezoid/parafacial region. Based on these results, one-day-old mice could highlight characteristics for modeling the breathing network of premature infants. PMID:28018238

  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.

    Objective The objective of this study was to explore the potential of the Infant/Toddler Sensory Profile (ITSP) as a screening tool for autism spectrum disorders (ASD) in prematurely born children. Methods Parents of 157 children with birth weights <1,500 g (aged 2 years, corrected for prematurity; 88 boys, 69 girls) completed a screening battery that included the ITSP, Modified Checklist for Autism in Toddlers (M-CHAT), and the Communication and Symbolic Behavior Scales Developmental Profile Infant-Toddler Checklist (CSBS-DP-ITC). Children with known disabilities were excluded. All the children who were screened positive on any of the screening tools subsequently underwent clinical examination including the Autism Diagnostic Observation Schedule. Results We used classification trees to answer the question whether ITSP (or some of its subscales) could be combined with the M-CHAT and/or the CSBS-DP-ITC or its subscales into an effective ASD screening tool. Using the CSBS-DP-ITC, overall score, and the Sensation Seeking subscale of the ITSP, we obtained a screening tool that was able to identify all of the ASD children in our sample (confirmed by cross-validation). The proposed screening tool is scored as follows: 1) if the overall CSBS-DP-ITC value is <45.5, then the screening is positive; 2) if the overall CSBS-DP-ITC value is ≥45.5 and the z-score of the Sensation Seeking subscale of ITSP is ≥1.54, then the screening is positive; 3) otherwise, the screening is negative. Conclusion The use of CSBS-DP-ITC in combination with the Sensation Seeking subscale of the ITSP improved the accuracy of autism screening in preterm children. PMID:28182143

    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 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

    Gastroesophageal reflux disease (GERD) is a common problem in neonatology. Various physiological protective reflex responses provide a plausible biological link between gastro-esophageal reflux and apnea and bradycardia in premature. It is uncertain whether or not there is a causal relationship between the two diseases. However there is no consensus about the clinical and paraclinical diagnosis. Further explorations and treatment offered to premature infants with symptoms are discussed. We report the case of a preterm infants admitted to neonatal intensive care and with apnea and bradycardia. Clinical examination and exploration results were normal. We retained the gastrointestinal reflux diagnosis complicated of apnea and bradycardia. Pharmacological therapy for gastro-esophageal reflux disease has not definitively been shown to be effective in improving symptoms and should be reserved especially for infants with treatment refractory apnea and bradycardia episodes suspected as being gastro-esophageal reflux in premature infants. From a case report we made a literature review to discuss at length the different aspects of the problem.

    Prematurity continues to be the leading cause of neonatal death and developmental disability, highlighting the importance of identifying potential predictors of prematurity as well as interventions that can be linked to the predictors. This review covers recent research on potential psychological, physiological, and biochemical predictors. Among the psychological stressors are depression, anxiety, difficult relationships, and lack of social support. Biochemical predictors include corticotropin-releasing hormone, cortisol, and fetal fibronectin. A program of research that links an intervention for prematurity with a predictor for prematurity, that is, massage therapy to reduce cortisol and, in turn, reduce prematurity, is then presented.

    A multicenter retrospective study was conducted to investigate the perinatal factors, imaging findings and clinical characteristics of hemiplegic cerebral palsy with a particular focus on children born prematurely. Our cohort included 135 patients of whom 42% were born prematurely; 16% were extreme premature infants who were born at 30 weeks or earlier. Nineteen (14%) were twins. Right hemiplegia was slightly more common and accounted for 59% of the patients. Imaging findings of intraventricular hemorrhage and periventricular leukomalacia were more prevalent in premature children whereas stroke, porencephaly, cerebral hemorrhage and cerebral atrophy were more evenly distributed in both term-born and prematurely-born children (p< 0.01). The overall prevalence of epilepsy in the cohort was 26% with no differences in full-term compared to prematurely-born children. Regardless of the gestational birth age, intellectual deficits were more common in the presence of comorbidity of both hemiplegia and epilepsy (p< 0.05).

    The development of an affectionate parent-infant bond is essential for a newborn infant's survival and development. However, from evolutionary theory it can be derived that parental bonding is not an automatic process, but dependent on infants' cues to reproductive potential and parents' access to resources. The purpose of the present study was to examine the process of bonding in a sample of Dutch mothers (n = 200) and fathers (n = 193) of full-term (n = 69), moderately premature (n = 68), and very premature infants (n = 63). During the first month postpartum parents completed the Pictorial Representation of Attachment Measure (PRAM) and Postpartum Bonding Questionnaire (PBQ). Longitudinal analyses revealed that mothers' PRAM scores decreased after moderately preterm delivery, whereas decreases in PRAM scores occurred in both parents after very preterm delivery. As lower PRAM scores represent stronger feelings of parent-infant connectedness, our findings suggest a higher degree of bonding after premature childbirth. Results of the PBQ analysis were in line with PRAM outcomes, as parents of preterm infants reported less bonding problems compared to parents of full-terms. These findings support the hypothesis that in affluent countries with adequate resources, bonding in parents of preterm infants on average may be higher than in parents of full-term infants.

    Anaemia is a common problem in premature infants and is generally easy to treat with iron supplementation. If the anaemia persists despite appropriate correction of deficiencies, more extensive evaluation is required. We describe a case of a premature male infant with a production-deficient anaemia without metabolic deficiencies, eventually identified as anaemia of prematurity. This type of anaemia is commonly diagnosed but its highly variable and complex aetiology and phenotype are often poorly understood. A probable explanation for the anaemia of prematurity in this case was a transient iron incorporation defect, identifiable by high levels of zinc protoporphyrin.

    PurposeTo identify the risk factors for, and clinical features and treatment outcomes of aggressive posterior retinopathy of prematurity (APROP) in Korean infants.MethodsAmong 770 premature infants who underwent screening, 105 infants (198 eyes, 13.63%) received treatment for ROP. A total of 24 infants (48 eyes, 3.12%) developed APROP while 81 infants (150 eyes, 10.52%) developed non-APROP treatment-requiring type. The medical records of ROP-treated infants were reviewed retrospectively. The associated systemic and maternal risk factors were analyzed and anatomical outcomes were compared according to the severity of ROP and treatment modalities.ResultsThe mean gestational age and birth weight at birth in the APROP group were significantly lower than those in the non-APROP group (P=0.019, P<0.001, respectively). Infants who were born small for their GA developed APROP more frequently than non-APROP patients (P<0.001). Chorioamnionitis-positive infants also showed higher incidence rate of APROP (APROP vs non-APROP; P<0.001 and zone I APROP vs posterior zone II APROP; P=0.036, respectively). Infants with APROP required heavier laser treatment with a higher retreatment rate compared to infants with non-APROP. Favorable anatomical outcomes were achieved in 95.3% from treatment-requiring non-APROP group, 85.7% from zone I APROP and 84.6% from posterior zone II APROP group.ConclusionIntrauterine growth restriction and chorioamnionitis were associated with development of APROP. These findings suggest that perinatal maternal environment inhibiting normal retinal vascular growth in utero may contribute to increasing the risk of APROP in premature infants.Eye advance online publication, 24 February 2017; doi:10.1038/eye.2017.18.

    Dilation and abnormal tortuosity of retinal vessels are the hallmarks of severe retinopathy of prematurity (ROP) in premature infants. The stages of ROP are defined by vessel appearance at the interface between the vascular and avascular retinal areas. Deregulated signaling pathways involving hypoxia-inducible factors such as vascular endothelial growth factor (VEGF) are involved in the pathogenesis of ROP. VEGF-antagonists are increasingly being used as 'off-label medication' to treat this condition, with some success. We present Baby SM (female), who was born prematurely at 24 weeks gestation in a tertiary neonatal intensive care unit, and with a birth weight of 640 g. On screening at 35 weeks postmenstrual age (PMA), she was noted to have ROP, which became severe by 37 weeks PMA. She received one dose of intravitreal VEGF antagonist (Bevacizumab), resulting in a decrease in vessel tortuosity and dilation. However, repeat imaging at 4 weeks showed a re-emergence of vessel tortuosity. We believe the observed changes demonstrate an inherent retinal microvascular plasticity in premature neonates. With improved survival of extremely premature neonates and the availability of retinal imaging technology, we are now able to observe this plasticity.

    1977-03-01

    In a prospective study of 133 spontaneous premature deliveries the relation between premature rupture of the membranes (PRM) and development of respiratory distress syndrome (RDS) in newborn infants is examined. PRM is associated with a significantly decreased incidence of RDS in newborn infants (P less than 0.002). This relation is valid at a gestational age of 28 weeks or more and a birthweight greater than 1000 g. Total respiratory morbidity in newborn infants (transient tachypnea + RDS) is also significantly decreased when labor is associated with PRM (P less than 0.005). Assessment of the influences of sex of the infant, fetal asphyxia, and delivery by cesarian section shows that PRM bears a stronger relation than each of these individual factors to a decreased incidence of RDS. Duration of the latent period has no influence on protection from RDS, and it is suggested that fetal lung maturity occurs before the membranes rupture.

    In 1% of women, premature ovarian failure develops by 40 years of age, a condition causing amenorrhea, infertility, sex steroid deficiency, and elevated gonadotropins. Early loss of ovarian function has significant psychosocial sequelae and major health implications. These young women have a nearly two-fold age-specific increase in mortality rate. Among women with spontaneous premature ovarian failure who have a normal karyotype, half have ovarian follicles remaining in the ovary that function intermittently. Indeed, pregnancies have occurred after the diagnosis of premature ovarian failure. Thus, premature ovarian failure should not be considered as a premature menopause. Young women with this disorder have a 5% to 10% chance for spontaneous pregnancy. Attempts at ovulation induction using various regimens fail to induce ovulation rates greater than those seen in untreated patients; however, oocyte donation for women desiring fertility is an option. Young women with premature ovarian failure need a thorough assessment, sex steroid replacement, and long-term surveillance to monitor therapy. Estrogen-progestin replacement therapy should be instituted as soon as the diagnosis is made. Androgen replacement should also be considered for women with low libido, persistent fatigue, and poor well-being despite taking adequate estrogen replacement. Women with premature ovarian failure should be followed up for the presence of associated autoimmune endocrine disorders such as hypothyroidism, adrenal insufficiency, and diabetes mellitus.

    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.

    During the 1920s and 1930s, a number of physicians created model premature infant stations in select hospitals, arguing that medicine could successfully treat premature infants, most of whom could be expected to live normal lives. Most hospitals and doctors, however, remained indifferent to the special medical needs of premature infants. Subsequently, public health officials, beginning in Chicago, took up the cause of the medical management of newborn premature infants, defining the problem and finding the resources for a community-wide solution. The latter included multiple, high-quality premature nurseries, infant transport, regionalization, and public financing. The "Chicago model" was adapted by many state and municipal departments of health, particularly after World War II, to create community-based programs, the largest of which was in New York City. As premature infant care became of greater interest to pediatricians and hospitals, in part because of the success achieved by public health officials, the earlier, prominent role of the latter was increasingly diminished and historically forgotten.

    Premature infants have altered glucose regulation early in life and increased risk for diabetes in adulthood. Although prematurity leads to an increased risk of diabetes and metabolic syndrome in adult life, the role of hepatic glucose regulation and adaptation to an early extra-uterine environment in preterm infants remain unknown. The purpose of this study was to investigate developmental differences in glucose metabolism, hepatic protein content and gene expression of key insulin signaling/gluconeogenic molecules. Fetal baboons were delivered at 67%, 75%, and term gestational age and sacrificed at birth. Neonatal baboons were delivered prematurely (67% gestation) and survived for 2 weeks, and compared to similar postnatal term animals and underwent serial hyperinsulinemic-euglycemic clamp studies. Premature baboons had decreased endogenous glucose production compared to term animals. Consistent with these results, the gluconeogenic molecule, PEPCK mRNA, was decreased in preterm baboons compared to terms. Hepatic insulin signaling was altered by preterm birth as evidenced by decreased insulin receptor (IR)-β, p85 subunit of PI3K, phosphorylated IRS-1, and Akt-1 under insulin stimulated conditions. Furthermore, preterm baboons failed to have the normal increase in GSK-3 from fetal to postnatal life. The blunted responses in hepatic insulin signaling may contribute to the hyperglycemia of prematurity, while impaired endogenous glucose production leads to hypoglycemia of prematurity.

    A retrospective study was conducted of all live births occurring in 1992 at a Dominican Institute of Social Security hospital in Santo Domingo to analyze the association between prematurity, low birth weight, and early neonatal mortality. Stillbirths, infants weighing less than 1000 g or born before 28 weeks of gestation, and those with lethal malformations were excluded. 5142 newborns met the inclusion criteria. 1701 deliveries (33%) were cesarean. 550 of the newborns (10.7%) were low birth weight, and 338 (6.6%) were premature. The early neonatal mortality rate was 17/1000. Low birth weight infants accounted for 66.2% of early neonatal mortality. 10.7% of low birth weight infants died within the first week of life, and their relative risk of early neonatal death was 16.42. 64% of all infants dying in their first week of life were also premature. The specific mortality rate for premature infants was 168.6/1000 live births. The relative risk was 25.32 for premature infants. Low birth weight infants born at term had an early neonatal mortality rate of 24.6/1000 live births, compared to 5.5/1000 for term births of adequate weight.

Available data evaluating the immune response of preterm infants support early immunization without correction for gestational age. For a number of antigens, the antibody response to initial doses of vaccines may be lower than that of term infants, but protective concentrations are often achieved and memory successfully induced. Vaccines are immunogenic, safe and well tolerated in preterm infants. Preterm infants should be vaccinated using the same schedules as those usually recommended for full-term infants, with the exception of the hepatitis B vaccine, where additional doses should be administered in infants receiving the first dose during the first days of life if they weighed less than 2000 g because of a documented reduced immune response.

    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

    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.

    Retinopathy of Prematurity (ROP) is a leading cause of childhood blindness in the United States. Optical Coherence Tomography (OCT) is a relatively new imaging technology capable of imaging ocular structures in cross section at high resolution. We present an age-customized approach to perform Spectral Domain OCT in neonates and infants, and from SDOCT, the in-vivo development of the human fovea during the premature period up through term birth along with retinal changes unique to premature infants with ROP. Finally, we explore how this novel information may affect our understanding of ROP and the possible implications in vision and retinal development.

  14. Autoimmune premature ovarian failure

    PubMed Central

    2017-01-01

    Premature ovarian failure (POF), also termed as primary ovarian insufficiency (POI), is a highly heterogenous condition affecting 0.5-3.0% of women in childbearing age. These young women comprise quite a formidable group with unique physical and psychological needs that require special attention. Premature ovarian senescence (POS) in all of its forms evolves insidiously as a basically asymptomatic process, leading to complete loss of ovarian function, and POI/POF diagnoses are currently made at relatively late stages. Well-known and well-documented risk factors exist, and the presence or suspicion of autoimmune disorder should be regarded as an important one. Premature ovarian failure is to some degree predictable in its occurrence and should be considered while encountering young women with loss of menstrual regularity, especially when there is a concomitant dysfunction in the immune system.

  17. Feeding premature neonates: Kinship and species in translational neonatology.

    PubMed

    Dam, Mie S; Juhl, Sandra M; Sangild, Per T; Svendsen, Mette N

    2017-04-01

    Kinship, understood as biogenetic proximity, between a chosen animal model and a human patient counterpart, is considered essential to the process of 'translating' research from the experimental animal laboratory to the human clinic. In the Danish research centre, NEOMUNE, premature piglets are fed a novel milk diet (bovine colostrum) to model the effects of this new diet in premature infants. Our ethnographic fieldwork in an experimental pig laboratory and a neonatal intensive care unit (NICU) in 2013-2014 shows that regardless of biogenetics, daily practices of feeding, housing, and clinical care hold the potential for stimulating and eroding kinship relations between human and nonhuman actors. In the laboratory, piglets and researchers form 'interspecies-milk-kinships' that entail the intimate care crucial to keeping the compromised piglets alive during the experiments, thereby enhancing what the researchers refer to as the 'translatability' of the results. In the NICU, parents of premature infants likewise imagine a kind of interspecies kinship when presented with the option to supplement mother's own milk with bovine colostrum for the first weeks after birth. However, in this setting the NICU parents may perceive the animality of bovine colostrum, and the background information obtained in piglets, as a threat to the infants' connection to their biological parents as well as the larger human collective. Our study argues that the 'species flexibility' of premature beings profoundly shapes the translational processes in the field of neonatology research.

    2012-09-01

    Research has shown a high rate of autism spectrum disorders among very low birth weight children over the past decade. This paper proposes a literature review on this topic. Two generations of research have followed one another. The first retrospective studies found a high rate of ASD among premature babies. The second generation of prospective studies underlined and relativized this risk. Prospective research using screening tools (M-CHAT) have found around 20 % ASD, whereas 2 studies assessing the actual diagnosis found 5 % and 8 % ASD, 10 to 12 times more than in the general population. A number of hypotheses have been put forward to explain these high rates of ASD: sensory impairment associated with prematurity, white matter abnormalities, and cerebellar impairment. The authors propose complex models that take into account neurological deficits and the effects of perinatal events on interactive dynamics between infants and their caregivers. These models aim to allow suitable prevention and care for premature children with autism, a heavy additional handicap.

    Synopsis Premature infants suffer significant respiratory morbidity during infancy with long-term negative consequences on health, quality of life, and health care costs. Enhanced susceptibility to a variety of infections and inflammation play a large role in early and prolonged lung disease following premature birth, though the mechanisms of susceptibility and immune dysregulation are active areas of research. This chapter will review aspects of host-pathogen interactions and immune responses that are altered by preterm birth and that impact chronic respiratory morbidity in these children. PMID:26593074

    2000-09-01

    The aim of the present study is to compare the health status of Armed Forces and civilian infants, accounting for social class. In a prospective cohort study, demographic data were obtained from mothers of liveborn infants from 436 civilian and 162 Armed Forces families. Birth details were taken from hospital maternity and child health systems. A six month follow-up was completed by health visitors. Standard social class classification, based on occupation, was used for civilian families and a new equivalent scheme for military personnel. No significant differences were found between civilian and military infants for birthweight, prematurity and failure to thrive. Military infants had significantly more hospital admissions (P=0.015) and accident and emergency attendances (P=0.002) mainly accounted for by the 'manual' social classes of the Armed Forces. Infant health status of civilian and military babies did not differ overall. Increased uptake of hospital services by military families can be explained by local circumstances.

    2015-01-01

    Chronic pain is highly prevalent in older adults, and until recently, was considered to be common but relatively "benign." Mounting evidence, however, suggests that some of the 116 million US adults who suffer from chronic pain are also at an increased risk for developing age-related diseases prematurely, suffering earlier cognitive and physical decline, and experiencing earlier mortality. Given the aging US population and the prevalence of chronic pain along with related healthcare consequences, there is a critical need to better understand the relationship between aging and chronic pain. Herein, we focus on one chronic pain state, fibromyalgia, and provide an overview of the evidence suggesting that individuals with this chronic pain condition show signs of premature aging.

    It is apparent from this review that the lifestyle of an individual gravida can potentially lead to a premature delivery. Some of these adverse behavioral characteristics may be dealt with by education and motivation, and some with actual medical treatment. However, there also appears to be significant need for public policy reorientation if we are to make a significant impact on the problem of preterm delivery.

  4. Prematurely terminated slug tests

    SciTech Connect

    Karasaki, K. )

    1990-07-01

    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.

  5. Metabolic maturation of white matter is altered in preterm infants.

    2014-01-01

    Significant physiological switches occur at birth such as the transition from fetal parallel blood flow to a two-circuit serial system with increased arterial oxygenation of blood delivered to all organs including the brain. In addition, the extra-uterine environment exposes premature infants to a host of stimuli. These events could conceivably alter the trajectory of brain development in premature infants. We used in vivo magnetic resonance spectroscopy to measure absolute brain metabolite concentrations in term and premature-born infants without evidence of brain injury at equivalent post-conceptional age. Prematurity altered the developmental time courses of N-acetyl-aspartate, a marker for axonal and neuronal development, creatine, an energy metabolite, and choline, a membrane metabolite, in parietal white matter. Specifically, at term-equivalency, metabolic maturation in preterm infants preceded development in term infants, but then progressed at a slower pace and trajectories merged at ≈340-370 post-conceptional days. In parieto/occipital grey matter similar trends were noticed but statistical significance was not reached. The timing of white matter development and synchronization of white matter and grey matter maturation in premature-born infants is disturbed. This may contribute to the greater risk of long-term neurological problems of premature infants and to their higher risk for white matter injury.

  6. Retinopathy of prematurity: New developments bring concern and hope.

    2015-08-01

    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.

    2015-01-01

    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.

    Beck-Peccoz, Paolo; Persani, Luca

    2006-01-01

    Premature ovarian failure (POF) is a primary ovarian defect characterized by absent menarche (primary amenorrhea) or premature depletion of ovarian follicles before the age of 40 years (secondary amenorrhea). It is a heterogeneous disorder affecting approximately 1% of women <40 years, 1:10,000 women by age 20 and 1:1,000 women by age 30. The most severe forms present with absent pubertal development and primary amenorrhea (50% of these cases due to ovarian dysgenesis), whereas forms with post-pubertal onset are characterized by disappearance of menstrual cycles (secondary amenorrhea) associated with premature follicular depletion. As in the case of physiological menopause, POF presents by typical manifestations of climacterium: infertility associated with palpitations, heat intolerance, flushes, anxiety, depression, fatigue. POF is biochemically characterized by low levels of gonadal hormones (estrogens and inhibins) and high levels of gonadotropins (LH and FSH) (hypergonadotropic amenorrhea). Beyond infertility, hormone defects may cause severe neurological, metabolic or cardiovascular consequences and lead to the early onset of osteoporosis. Heterogeneity of POF is also reflected by the variety of possible causes, including autoimmunity, toxics, drugs, as well as genetic defects. POF has a strong genetic component. X chromosome abnormalities (e.g. Turner syndrome) represent the major cause of primary amenorrhea associated with ovarian dysgenesis. Despite the description of several candidate genes, the cause of POF remains undetermined in the vast majority of the cases. Management includes substitution of the hormone defect by estrogen/progestin preparations. The only solution presently available for the fertility defect in women with absent follicular reserve is ovum donation. PMID:16722528

    2011-01-01

    SYNOPSIS Chronic, subacute decidual hemorrhage (i.e., abruptio placenta and retrochorionic hematoma formation) is an important contributor to preterm parturition. Such hemorrhage induces thrombin from decidual tissue factor, which play a pivotal role in the development of preterm premature rupture of membranes and preterm delivery by acting through protease-activated receptors to promote the production of pro-inflammatory cytokines, and matrix-degrading metalloproteinases. Severe, acute abruption can lead to maternal and fetal mortality. Current management of abruption is individualized based on severity of disease, underlying etiology, and gestational age.

    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.

    Premature physeal arrest may occur after various insults to the physis. Its association with diaphyseal fracture without obvious physeal damage is well known, but the cause is obscure. The case reported documents premature closure of the distal tibial physis of an infant after a temporary but significant episode of vascular insufficiency. Direct arterial occlusion or arterial spasm may account for some cases of physeal arrest associated with nonphyseal-related trauma.

    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

    PubMed Central

    Puntis, J W L

    2006-01-01

    The theory and practice of nutritional support in the premature newborn has assumed increasing importance with survival of greater numbers of very immature infants. After birth, many do not tolerate full enteral feeding until gastrointestinal motor function has matured. During this process some will develop necrotising enterocolitis (NEC), a devastating failure of adaptation to postnatal life that may result in death, or severe complications. The feeding strategy that minimises the risk of NEC remains to be defined. In addition, promoting growth rates and nutrient accretion equivalent to those achieved during fetal development while optimising neurodevelopmental and long term health outcomes represents an important challenge for neonatologists. This review will focus on the problems associated with enteral nutrition, the requirement for parenteral nutrition, and the long term consequences of early nutritional interventions, underlining the need for prolonged follow up in assessing the potential benefits of different approaches to feeding.

    2013-06-03

    Subcapsular haematoma of the liver rarely occurs in neonates and the diagnosis is often missed or delayed. It is a catastrophic condition that can be caused by maternal, placentar or fetal factors. A high index of suspicion is essential for early identification and stabilisation of babies with such a pathology. In a newborn with hypovolemic shock and abdominal distension, haemoperitoneum should be suspected and, along with exclusion of other aetiologies, supportive therapy should be instituted. The hepatic subcapsular haematoma has a non-specific presentation, and should be considered in very low birth weight infants with hypovolemic shock. Abdominal ultrasonography is the investigation of choice. It can delineate the lesion well, differentiate it from neoplasms, rule out rupture and aid in serial follow-up. We report a premature newborn who had this uncommon condition in the early neonatal period and survived without sequelae.

    2011-01-01

    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

    2014-01-01

    Premature ejaculation (PE) is a common male sexual disorder. It is defined by the Diagnostic and statistical manual of mental disorders as “ejaculation occurring, without control, on or shortly after penetration and before the person wishes it, causing marked distress or interpersonal difficulty.[1] Although the timing of intravaginal ejaculatory latency time (IELT) (i.e., time from penetration to ejaculation) is not included in this definition, an IELT of <2 min, or ejaculation occurring before penetration, has been considered consistent with PE.[2] Management involves both the patient and his partner. Therapeutic options should suit both partners and be appropriate to their habit in planning and frequency of intercourse. Follow-up at appropriate intervals to judge efficacy, titrate dosage of pharmacological treatments and ascertain side effects is mandatory. PMID:26396440

    Retinopathy of prematurity (ROP) is a neurovascular disease that affects prematurely born infants and is known to have significant long term effects on vision. We conducted the studies described herein not only to learn more about vision but also about the pathogenesis of ROP. The coincidence of ROP onset and rapid developmental elongation of the rod photoreceptor outer segments motivated us to consider the role of the rods in this disease. We used noninvasive electroretinographic (ERG), psychophysical, and retinal imaging procedures to study the function and structure of the neurosensory retina. Rod photoreceptor and post-receptor responses are significantly altered years after the preterm days during which ROP is an active disease. The alterations include persistent rod dysfunction, and evidence of compensatory remodeling of the post-receptor retina is found in ERG responses to full-field stimuli and in psychophysical thresholds that probe small retinal regions. In the central retina, both Mild and Severe ROP delay maturation of parafoveal scotopic thresholds and are associated with attenuation of cone mediated multifocal ERG responses, significant thickening of post-receptor retinal laminae, and dysmorphic cone photoreceptors. These results have implications for vision and control of eye growth and refractive development and suggest future research directions. These results also lead to a proposal for noninvasive management using light that may add to the currently invasive therapeutic armamentarium against ROP.

    This study focuses on the repercussions of prematurity for the growth and development of newborns from hospitals in Guadalajara, Jalisco, Mexico, typical of the health care system in Mexico. Infants were assessed every six months as to nutritional status and the Denver Selective Test. In analyzing the results, social groups were considered determinant categories for studying prematurity as the dependent variable. The results shows that both prematurity and social group are risk factors to be considered by the public health field when designing health care programs.

    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.

    Purpose. To examine the macular findings obtained with spectral domain optical coherence tomography (SD OCT) in infants with retinopathy of prematurity (ROP). Materials and Methods. The macular SD OCT images of 190 premature infants were analyzed. Data regarding central foveal thickness (CFT), cystoid macular edema (CME), and cyst grading were compared. The relationships of CFT with gestational age and birth weight were investigated. Results. The results were obtained from 358 eyes of 179 infants (81 females and 98 males) of a mean gestational age of 30.9 ± 2.7 weeks and a mean birth weight of 1609 ± 477 g. ROP was diagnosed in 126 eyes and CME in 139 eyes. A significantly greater percentage of eyes with ROP were found to have CME (54%) compared to eyes without ROP (31%; P = 0.001). The incidence of CME was 46.3% for stage 1 ROP, 57.1% for stage 2, and 87.5% for stage 3. There was a weakly inverse correlation between CFT, gestational age, and birth weight (P = 0.025, r = −0.227; P = 0.002, r = −0.182, resp., Spearman correlation test). Conclusions. High-quality SD OCT images can be obtained from premature infants using the iVue system. Severity and frequency of CME in premature infants increase as stage of ROP increases. PMID:25544895

    Infants born prematurely at <37 weeks' gestation account for over 80% of infants weighing <2,500 g at birth-low birth weight (LBW) infants. This designation remains the surrogate marker for developmental origins of adult disease. Landmark studies spanning four decades have shown that individuals born with a LBW are more likely to develop cardiovascular and renal disease in later life, which is believed to be related to 'developmental programming' of such adult disease during vulnerable periods of growth in utero and in the early postnatal period. There has long been ambiguity regarding the distinction between infants with intrauterine growth restriction and preterm infants since both show a low nephron endowment that is associated with subsequent hypertension and chronic kidney disease. Knowledge is growing specific to the preterm infant and the developmental associations of being born preterm with the interruption of normal organogenesis relative to the vascular tree and kidney. Both systems develop by branching morphogenesis and interruptions lead to considerable deficits in their structure and function. These developmental aberrations can lead to endothelial dysfunction, hypertension, proteinuria and metabolic abnormalities that persist throughout life. This Review will examine the effect of preterm birth on the development of cardiovascular and kidney disease in later life and will also discuss potential early interventions to alter the progression of disease.

    Survival rates of premature infants have increased with developing technology and evolving knowledge but late-onset sepsis is more frequent due to prolonged hospitalization periods of these infants. We report the case of an extremely low birth weight premature infant who was admitted with respiratory distress syndrome, developed necrotizing enterocolitis and fungal sepsis with endocarditis by Candida albicans. He was treated with antifungal therapy until fungal vegetation resolved. Fungal sepsis and endocarditis may be an important morbidity in preterm infants; we review the recent literature about the risk factors, diagnosis, treatment and prevention of fungal sepsis in these high risk infants.

    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

    Infant botulism is a rare disease that affects infant less than 12 months of age. The illness results from absorption of botulinum toxin produced in situ by neurotoxigenic clostridia that can temporarily colonize the intestinal tract of infants. To date, all inhabited continents except Africa have reported cases of infant botulism. Recognition of cases seem directly related to physician awareness and clinical suspicion. This review summarizes microbiological, clinical and epidemiological features of infant botulism.

    In spite of its high prevalence and long history, the ambiguity regarding the definition, epidemiology and management of premature ejaculation continues. 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. Further research is required to develop better options for the treatment of this common sexual disorder. PMID:25184045

    In prematurely born children, various visual and ophthalmologic sequelae occur because of both retinopathy of prematurity (ROP) and preterm birth per se. Several long-term follow-up studies have described the outcome of ROP. Visual impairment and blindness are well-known consequences, but the prevalence varies globally because of differing neonatal and ophthalmologic care. Improving treatment options and criteria for the treatment of ROP are continuously changing the ophthalmologic outcome. The anatomic outcome has improved with treatment, but good anatomic outcome in treated severe ROP does not always reflect the functional outcome. There is no consensus regarding long-term follow-up of prematurely born children.

    2008-01-01

    The use of music as part of a stress reduction therapy has been applied both to premature infants and their parents in the Neonatal Reanimation Service. This aim of music therapy amounts to an attempt to help the premature infant regaining its physical and neurological balance, so important to its psychological and physical development, mainly by masking the sometimes excessive noise present in the intensive care unit and/or in the incubator. Studies have demonstrated the positive impact of music therapy on oxygen saturation, heartbeat, and on the general level of relaxation experienced by premature infants. In this project, the palliative technique used was that of live singing, directly to the infant, accompanied by a pentatonic harp. The aim was to improve the state of health, both physical and psychological, of a group of premature infants, whose gestation period varied between 23 and 36 weeks. The technique used was to apply what amounts to a protective cocoon of sounds to a premature infant in the neonatal unit, which measurably reduced the level of stress as indicated by the babies' increasingly relaxed demeanour and induced a measurable increase on the level of oxygen saturation and a reduction of heart rate.

    Aim To investigate how 1) maternal delivery mode and 2) prematurity in infants are associated to antibiotic treatment and length of hospital stay. Methods Women having given birth and infants 0–12 months discharged from hospital between July 2005 and November 2011 were identified from the Swedish National Patient Register. Medical records were reviewed for 203 women and 527 infants. The risk ratio (RR) between antibiotic treatment and 1) delivery mode in women; 2) prematurity in infants was calculated. Length of stay and days of antibiotic therapy were compared by Wilcoxon rank-sum test. Results Women: There was an association between emergency caesarean section (CS) and antibiotic treatment (RR 5.0 95% confidence interval (CI) 2.2–11.5), but not for elective CS. Length of stay was longer for CS (emergency and elective) compared to vaginal delivery (p<0.01). Infants: RR for antibiotic treatment in preterm compared to term infants was 1.4 (95% CI 1.0–1.9). Length of stay (p<0.01), but not days of therapy (p = 0.17), was higher in preterm compared to term infants. Conclusion We found that emergency CS increased the probability of maternal antibiotic treatment during hospitalisation, but no difference was found between term and preterm infants. The results are well aligned with current guidelines and may be considered in future studies on the effects of antibiotics. PMID:27716779

    2015-01-01

    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. While infant colic is often assumed to have a gastrointestinal cause, several treatment trials aimed at gastrointestinal etiologies have been negative. Teaching parents how best to respond 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”.

    Premature ovarian failure occurs in approximately 1:1000 women before 30 years, 1:250 by 35 years and 1:100 by the age of 40. It is characterized by primary or secondary amenorrhea and cannot be considered as definitive because spontaneous conception may occur in 5 to 10% of cases. In 95% of cases, premature ovarian failure is sporadic. The known causes of premature ovarian failure include chromosomal defects, autoimmune diseases, exposure to radiation or chemotherapy, surgical procedures, and certain drugs. Frequently, however, the etiology is not clear and these cases are considered to be idiopathic. Premature ovarian failure is defined by gonadal failure and high serum follicle-stimulating hormone (FSH) levels. Clinical approach includes emotional support, hormonal therapy with estrogens and progesterone or progestogens, infertility treatment, and prevention of osteoporosis and potential cardiovascular risk.

    Retinopathy of prematurity occurs because the retina of a preterm infant at birth is incompletely vascularized, and if the postnatal environment does not match the in utero environment that supported retinal development, the vessels and neural retina will not grow normally. Risk factors determined from many clinical studies and animal studies fall into 2 categories: prenatal factors and postnatal factors.

    Objective To examine the relationship between the cause or severity of hypotension and the development of severe retinopathy of prematurity (sROP) (≥ stage 3 or stage 2 with plus disease in Zone I or II).. Study design Infants (<28 weeks’ gestation, n=242) were observed for hypotension and treated with a standardized hypotension-treatment protocol. Hypotension was classified as resulting from one of the following causes: (a) culture-positive infection and/or necrotizing enterocolitis, (b) PDA ligation, or (c) “idiopathic” (no cause identified other than prematurity), and as being either dopamine-responsive or dopamine-resistant. Cortisol levels were measured for infants with dopamine-resistant hypotension. Eye examinations were performed until the ROP resolved or the vasculature matured. Multivariable logistic regression analysis was performed to determine the relationship between the cause/severity of hypotension and sROP. Results Overall, 66% of infants developed hypotension (41% were dopamine-responsive and 25% were dopamine-resistant). sROP developed in 19% of infants. “Idiopathic” dopamine-resistant hypotension was the only cause significantly related to sROP. 66% of infants with dopamine-resistant hypotension had low serum cortisol (≤10 μg/dL). Low cortisol, in the presence of dopamine-resistant hypotension, was significantly associated with sROP and accounted for the relationship between “idiopathic” hypotension and sROP. When low cortisol was included in statistical models, other known risk factors, such as immature gestation, were no longer significantly related to sROP. Conclusion Low cortisol, in the presence of dopamine-resistant hypotension, has the greatest magnitude of association with sROP. PMID:23465406

    Objective To evaluate the role of serum apelin as a diagnostic tool in retinopathy of prematurity (ROP) disease. Patients and methods Thirty-eight preterm infants (60% male) with gestational age ranging from 30 to 36 weeks admitted to the neonatal intensive care unit, KJO Hospital, Saudi Arabia with proven diagnosis of ROP were included in the study. In addition, 27 preterm infants without ROP served as controls. All newborn infants in the study were subjected to adequate history taking, full clinical examination, and fundus examination by indirect ophthalmoscope (at 4–6 weeks) as well as determination of serum apelin at birth and at 4–6 weeks of age. Results The study revealed that oxygen therapy longer than 7 days’ duration, cesarean section (as a mode of delivery), sepsis, mechanical ventilation, blood transfusion, premature rupture of membranes, pneumothorax, perinatal asphyxia, cardiac problems, and neonatal jaundice were considered as risk factors related to development of ROP. Serum apelin levels were significantly lower in patients than controls (P<0.001) at time of diagnosis of the disease (4–6 weeks) while no significant differences were observed in levels at birth. Conclusion Serum apelin was found to be of significant diagnostic value in the occurrence of ROP. PMID:28260850

    Fetal and neonatal inflammation is associated with several morbidities of prematurity. Its relationship to retinopathy of prematurity (ROP) has not been investigated. Our objective was to determine the relationship between cytokine levels and ROP in the first three postnatal weeks. Data for this study were derived from the NICHD Cytokine Study. Dried blood spots were obtained from infants <1000g on days 0-1, 3±1, 7±2, 14±3, and 21±3. Infants were classified into three groups – No, Mild, and Severe ROP. Multiplex Luminex assay was used to quantify 20 cytokines. Temporal profiles of cytokines were evaluated using mixed effects models after controlling for covariates. Of 1074 infants enrolled, 890 were examined for ROP and 877 included in the analysis. ROP was associated with several clinical characteristics on unadjusted analyses. Eight cytokines remained significantly different across ROP groups in adjusted analyses. IL-6 and IL-17 showed significant effects in early time periods (D0-3); TGF-β, brain derived neurotrophic factor (BDNF), and regulated upon activation, normal T cell expressed and secreted (RANTES) in later time periods (D7-21) and IL-18, C-reactive protein (CRP) and neurotrophin-4 (NT-4) in both early and later time periods. We conclude that perinatal inflammation may be involved in the pathogenesis of ROP. PMID:20032809

    We examine the coherence in the spontaneous brain activity of sleeping children as measured by the blood oxygenation level dependent (BOLD) functional magnetic resonance imaging (fMRI) signals. The results are described in terms of resting-state networks (RSN) and their properties. More specifically, in this study we examine the effect of severe prematurity on the spatial location of the visual, temporal, motor, basal ganglia, and the default mode networks, the temporal response properties of each of these networks, and the functional connectivity between them. Our results suggest that the anatomical locations of the RSNs are well developed by 18 months of age and their spatial locations are not distinguishable between premature and term born infants at 18 months or at 36 months, with the exception of small spatial differences noted in the basal ganglia area and the visual cortex. The two major differences between term and pre-term children were present at 36 but not 18 months and include: (1) increased spectral energy in the low frequency range (0.01–0.06 Hz) for pre-term children in the basal ganglia component, and (2) stronger connectivity between RSNs in term children. We speculate that children born very prematurely are vulnerable to injury resulting in weaker connectivity between resting-state networks by 36 months of age. Further work is required to determine whether this could be a clinically useful tool to identify children at risk of developmental delay related to premature birth. PMID:20725534

    The aim of this study was to generate reference ranges for aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in preterm infants by describing the observed plasma concentration of these enzymes in babies born between 22 and 36 weeks' gestation. A service evaluation was conducted in babies admitted to two large neonatal intensive care units in the UK. 7006 blood samples from 1860 infants admitted to the two units between 2004 and 2008 were included. Extremely premature infants had high plasma enzyme activities when compared to babies at a later corrected gestational age. This may be due to more severe illness immediately after birth.

    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.

    2006-12-01

    The aim of this longitudinal study was to investigate the effect of a set of factors from multiple levels of influence: infant temperament, infant regulatory behavior, and maternal sensitivity on infant's attachment. Our sample consisted of 48 infants born prematurely and their mothers. At 1 and 3 months of age, mothers described their infants' behavior using the Escala de Temperamento do Bebé. At 3 months of age, infants' capacity to regulate stress was evaluated during Tronick's Face-to-Face Still-Face (FFSF) paradigm. At 9 months of age, mothers' sensitivity was evaluated during free play using the CARE-Index. At 12 months of age, infants' attachment security was assessed during Ainsworth's Strange Situation. A total of 16 infants were classified as securely attached, 17 as insecure-avoidant, and 15 as insecure-resistant. Mothers of securely attached infants were more likely than mothers of insecure infants to describe their infants as less difficult and to be more sensitive to their infants in free play. In turn, secure infants exhibited more positive responses during the Still-Face. Infants classified as insecure-avoidant were more likely to self-comfort during the Still-Face and had mothers who were more controlling during free play. Insecure-resistant exhibited higher levels of negative arousal during the Still-Face and had mothers who were more unresponsive in free play. These findings show that attachment quality is influenced by multiple factors, including infant temperament, coping behavior, and maternal sensitivity.

    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.

    Infant botulism is a paralytic syndrome which manifests as a result of ingesting spores of the toxin secreting bacterium Clostridium botulinum by infants. As opposed to botulism in adults, treating infant botulism with horse antiserum was not approved due to several safety issues. This restriction has led to the development of Human Botulism Immune Globulin Intravenous (BIG-IV; sells under BabyBIG). In this article we review infant botulism and the advantages of treating it with BIG-IV.

    Asthma is the most common chronic disease of childhood, affecting millions of children in the U.S. 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 not only cause 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: 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 co-morbidities. While awaiting the results of such studies, sound policies to prevent domestic and community violence (e.g. 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.

    Introduction: Retinopathy of Prematurity (ROP) represent disease of the eye in premature born children which affects immature blood vessels of the retina during their development. The emergence of retinopathy of prematurity depends on the interaction of multiple factors, such as: gestational age, low birth weight, hypoxia, duration of oxygen supplementation, respiratory distress syndrome, twin pregnancy, anemia, blood transfusions, sepsis, intraventricular hemorrhage, hypotension, hypothermia, etc. If remain unrecognized and untreated it can cause severe visual impairment and blindness in children, but can also be prevented with timely screening. Goals: To establish the number of patients with development of retinopathy of prematurity active forms in the observed time period and examine which risk factors have most significant impact on its origin. Material and methods: In a clinical, retrospective study we observed a total of 80 premature born children in the period from January to May 2015 with regard to listed risk factors identified for eye examination. Results: From a total of 80 premature newborns sample included 48.8% male and 51.2% female children. The active form of ROP developed in 6.2% of cases, while in 93.8% of cases there was a spontaneous resolution. Patients who developed active form of ROP have significantly younger gestational age (26.4±1.5 weeks) and lower birth weight (874±181 grams), lower Apgar score in the first and fifth minute and were longer on oxygen therapy (20±3.4 days). Conclusion: Of the potential risk factors that could affect the development of ROP active form following factors have a statistically significant influence: early gestational age, low birth weight, lower Apgar score and prolonged oxygen therapy (p <0.05).

    Various drugs used to stop premature uterine contractions are discussed in the paper. Particular attention is paid to beta-mimetic drugs. The results of ming Partusisten, one of beta-mimetic drugs, is presented on the material of 104 patients with threatening immature and premature labour. Partusisten was administered in the form of intravenous drip infusion or tablets. During treatment monitoring of the uterine contractility and of foetal heart rate took place. Inhibition of the uterine contraction activity was successful in 100 per cent of cases. In 60,9 per cent in the group of threatening immature labour and in 38,1 per cent in the group threatening premature labour, the delay of delivery was more then 28 days. The delay of delivery by 48 hours was 87 per cent and 84 per cent in both groups respectively. Tachycardia was one of the first side effects observed in 15,2 per cent of cases. There is also presented an example of pregnancy when delivery was delayed by 21 days in spite of premature outflow of amniotic fluid (at a high rupture of membrane). The authors are of the opinion that Partusisten is very effective and gives little side effects, preventing premature uterine contractions. Dosage should be individualized according to the case and labour advancement, and should be based on topographic evaluation of uterine contraction. Negative influence of the drug on foetuses was not observed.

    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%.

LCPUFAs demonstrate cytoprotective and cytotherapeutic actions contributing to a number of anti-angiogenic and neuroprotective mechanisms within the retina. Their intake appears to have a beneficial effect on ischemia, oxidative stress, inflammation and cellular signaling mechanisms, influencing retinal cell gene expression and cellular differentiation. ω-3 LCPUFAs may modulate metabolic processes that activate molecules implicated in the pathogenesis of vasoproliferative and neurodegenerative retinal diseases such as ROP.

    Objective The aim of this RCT was to evaluate sucking organization in premature infants following a preterm infant multi-sensory intervention, the Auditory, Tactile, Visual, and Vestibular (ATVV). Study Design A convenience sample of 183 healthy premature infants born 29 - 34 weeks post-menstrual age (PMA) enrolled. Sucking organization was measured at baseline, then weekly assessments, during the infant's hospital stay. Results A quadratic trend was observed for number of sucks, sucks per burst, and maturity index, with the intervention group increasing significantly faster by day 7 (Model estimates for group*day: β = 13.69, p < 0.01; β = 1.16, p < 0.01; and β = 0.12, p < 0.05, respectively). Sucking pressure increased linearly over time, with significant between-group differences at day 14 (β = 45.66, p < 0.01). Conclusion ATVV infants exhibited improved sucking organization during hospitalization, suggestive that ATVV intervention improves oral feeding. PMID:25822519

    Preterm birth is a risk factor for deficits of neurological and cognitive development. Four cohort studies are reported investigating the effects of very premature birth (<32 weeks gestation) on visual, visuocognitive and visuomotor function between birth and 6-7 years of age. The first study used two measures of early visual cortical function, orientation reversal visual event-related potentials (OR-VERP) and fixation shifts under competition. Both these functional measures of visual development correlated with the severity of brain abnormality observed on structural MRI at and before term, and were sensitive predictors of neurodevelopmental outcome at 2 years. The second study compared VERP measures for orientation-reversal and direction-reversal (DR) stimuli, from 2 to 5 months post-term age, in healthy very premature infants compared to infants born at term. The groups did not differ on the development of OR-VERP responses, but the development of the DR-VERP motion responses was delayed in the premature group despite the absence of any brain damage visible on ultrasound, consistent with the developmental vulnerability we have identified in the dorsal cortical stream. The third study used the Atkinson Battery of Child Development for Examining Functional Vision (ABCDEFV) to assess sensory, perceptual, cognitive and spatial visual functions, together with preschool tests of attention and executive function. The premature group showed delays on these tests in line with severity of observed perinatal brain damage on structural MRI at term age. Deficits on certain spatial tasks (e.g. block-construction copying) and executive function tests (e.g. the detour box task) were apparent even in children with minimal damage apparent on MRI. The fourth study tested a large cohort of 6- to 7-year old children born before 32 weeks gestation, across a wide range of cognitive domains, including new tests of spatial cognition and memory. The premature group as a whole showed

    Retinopathy of Prematurity (ROP) is an infant disease characterized by increased dilation and tortuosity of the retinal blood vessels. Automatic tortuosity evaluation from retinal digital images is very useful to facilitate an ophthalmologist in the ROP screening and to prevent childhood blindness. This paper proposes a method to automatically classify the image into tortuous and non-tortuous. The process imitates expert ophthalmologists' screening by searching for clearly tortuous vessel segments. First, a skeleton of the retinal blood vessels is extracted from the original infant retinal image using a series of morphological operators. Next, we propose to partition the blood vessels recursively using an adaptive linear interpolation scheme. Finally, the tortuosity is calculated based on the curvature of the resulting vessel segments. The retinal images are then classified into two classes using segments characterized by the highest tortuosity. For an optimal set of training parameters the prediction is as high as 100%.

    Background Ecological and transactional theories link child outcomes to accumulated risk. This study hypothesized that cumulative risk was negatively related to attachment, and that maternal sensitivity mediated linkages between risk and attachment. Methods 112 high-risk African-American premature infant-mother dyads participated. Psychosocial (maternal depression, stress and self-efficacy) and sociodemographic risk (poverty, maternal education, marital status) were maternal self-report (0–4 months). Infant health risk was obtained from hospital charts. Infant-mother attachment (12 months) and maternal sensitivity (4 months) were assessed with Q-sort measures. Findings Psychosocial and sociodemographic, but not infant health risk, negatively related to attachment. Both were mediated by maternal sensitivity. Conclusions The impact of risk domains on attachment security was mediated by maternal sensitivity. Results emphasize the need for early intervention programs targeting premature infants to identify and address environmental and personal factors that place parenting at risk. PMID:21434913

    Premature children are prone to severe viral respiratory infections in early life, but the age at which susceptibility peaks and disappears for each pathogen is unclear. Methods: A retrospective analysis was performed of the age distribution and clinical features of acute viral respiratory infections in full-term and premature children, aged zero to seven years. Results: The study comprised of a total of 630 hospitalizations (n = 580 children). Sixty-seven percent of these hospitalizations occurred in children born full-term (>37 weeks), 12% in preterm (32–37 weeks) and 21% in severely premature children (<32 weeks). The most common viruses identified were rhinovirus (RV; 60%) and respiratory syncytial virus (RSV; 17%). Age-distribution analysis of each virus identified that severely premature children had a higher relative frequency of RV and RSV in their first three years, relative to preterm or full-term children. Additionally, the probability of RV- or RSV-induced wheezing was higher overall in severely premature children less than three years old. Conclusions: Our results indicate that the vulnerability to viral infections in children born severely premature is more specific for RV and RSV and persists during the first three years of age. Further studies are needed to elucidate the age-dependent molecular mechanisms that underlie why premature infants develop RV- and RSV-induced wheezing in early life. PMID:27775602

    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

    BACKGROUND AND OBJECTIVES: Delayed detection of type 1 retinopathy of prematurity (ROP) can lead to permanent visual impairment. Providing ROP examinations is challenging because of the limited ophthalmology workforce. This study compares digital imaging–based ROP detection strategies versus serial ROP examinations. METHODS: We conducted an individual-level microsimulation studyof a hypothetical cohort of 650 infants with gestational age from 23 to 30 weeks. Infants were evaluated by using strategies based on indirect ophthalmoscopy or digital imaging beginning at 32 weeks’ postmenstrual age (PMA) and continuing to discharge, transfer, or 40 weeks’ PMA. ROP status and the accuracy of digital imaging were based on the e-ROP (Telemedicine Approaches to Evaluating Acute-Phase ROP) study, which enrolled high-risk infants. RESULTS: Within the hypothetical NICU, the strategy of ROP examinations identified an average of 45.8 cases of type 1 ROP by discharge, transfer, or 40 weeks’ PMA, and another 1.9 cases were included in the group of infants recommended to have later follow-up. Digital imaging with an ROP examination at discharge identified all 47.7 cases of type 1 ROP. On average, the ROP examination–only strategy required 1745.7 ROP examinations, whereas digital imaging with a discharge examination required 1065.5 ROP examinations and 1786.2 digital imaging sessions. CONCLUSIONS: Although digital imaging decreased the number of ROP examinations per infant, there was an increase in the total number of interventions (ie, ROP examinations and imaging sessions). Providing an ROP examination at the time of NICU discharge can significantly reduce the number of infants who require follow-up. PMID:26672022

    Despite significant advances in perinatal medicine, the management of extremely preterm infants in the delivery room remains a challenge. There is an increasing evidence for improved outcomes regarding the resuscitation and stabilisation of extremely preterm infants but there is a lack of evidence in the periviable (gestational age 23-25 wk) preterm subgroup. 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. Evidence for antenatal steroids especially in the periviable infants, delayed cord clamping, strategies to establish optimal functional residual capacity, importance of temperature control and oxygenation in delivery room in extremely premature infants is reviewed in this article.

    Preterm birth affects about 10% of infants born in the United States. Massage therapy is being used in some neonatal intensive care units for its potential beneficial effects on preterm infants. This article reviews published randomized controlled trials on the effects of massage in preterm infants. Most studies evaluating the effect of massage in weight gain in premature infants suggest a positive effect on weight gain. Increase in vagal tone has been reported in infants who receive massage and has been suggested as a possible mechanism for improved weight gain. More studies are needed on the underlying mechanisms of the effects of massage therapy on weight gain in preterm infants. While some trials suggest improvements in developmental scores, decreased stress behavior, positive effects on immune system, improved pain tolerance and earlier discharge from the hospital, the number of such studies is small and further evidence is needed. Further studies, including randomized controlled trials, are needed on the effects of massage in preterm infants.

    OBJECTIVE: Ophthalmologic examination for retinopathy of prematurity is a painful procedure. Pharmacological and non-pharmacological interventions have been proposed to reduce pain during eye examinations. This study aims to evaluate the analgesic effect of 25% glucose using a validated pain scale during the first eye examination for retinopathy of prematurity in preterm infants with birth weight ≤1,500 g and/or gestational age ≤32 weeks. METHODS: A masked, randomized clinical trial for one dose of 1 ml of oral 25% glucose solution 2 minutes before the first ophthalmologic examination for retinopathy of prematurity was conducted between March 2008 and April 2010. The results were compared to those of a control group that did not receive oral glucose solution. Pain was evaluated using a Neonatal Infant Pain Scale immediately before and immediately after the ophthalmologic examination in both groups. Clinicaltrials.gov: NCT00648687 RESULTS: One hundred and twenty-four patients who were examined for the first time for retinopathy of prematurity were included. Seventy were included in the intervention group and 54 in the control group. The number of patients with pain immediately before the procedure was similar in both groups. The number of patients with pain after ophthalmologic examination was 15.7% in the intervention group and 68.5% in the control group (p<0.001). CONCLUSIONS: One ml of oral 25% glucose solution given 2 minutes before an ophthalmologic examination for retinopathy of prematurity was an effective measure for pain relief. PMID:23525316

    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

    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

  5. Toward a fuzzy logic control of the infant incubator.

    Premature birth is a world wide problem. Thermo regulation is a major problem in premature infants. Premature infants are often kept in infant incubators providing convective heating. Currently either the incubator air temperature is sensed and used to control the heat flow, or infant's skin temperature is sensed and used in the close loop control. Skin control often leads to large fluctuations in the incubator air temperature. Air control also leads to skin temperature fluctuations. The question remains if both the infant's skin temperature and the incubator air temperature can be simultaneously used in the control. The purpose of the present study was to address this question by developing a fuzzy logic control which incorporates both incubator air temperature and infant's skin temperature to control the heating. The control was evaluated using a lumped parameter mathematical model of infant-incubator system (Simon, B. N., N. P. Reddy, and A. Kantak, J. Biomech. Eng. 116:263-266, 1994). Simulation results confirmed previous experimental results that the on-off skin control could lead to fluctuations in the incubator air temperature, and the air control could lead to too slow rise time in the core temperature. The fuzzy logic provides a smooth control with the desired rise time.

    The influence of topical iodine-containing antiseptics on thyroid function test results of premature infants was determined in two separate studies. Thyroxine and thyrotropin levels were measured on blood-spotted filter paper. Samples were obtained from 128 premature infants on their tenth day of life; the infants were treated in two neonatal intensive care units. Both units used similar treatment protocols; however, one routinely used topical iodinated antiseptic agents (n = 73), whereas the other used chlorhexidine-containing antiseptics (n = 55). There was no difference in the mean T4 levels between the two groups. The mean thyrotropin levels were elevated in preterm babies exposed to iodine (15.4 vs 7.8 mIU/L, p < 0.01). Among the iodine-exposed infants, elevated thyrotropin levels (> 30 mIU/L) were found in 13.7% of infants, compared with none in the chlorhexidine-treated group (p < 0.01). We then studied an additional 46 premature infants who were treated in one neonatal intensive care unit. Iodine-containing solutions were used in 24 infants and chlorhexidine was used in 22 infants. T4 and thyrotropin levels were measured weekly during the first 28 days, one every 2 weeks until the age of 60 days, and at the age of 90 days. Among iodine-exposed infants, 20.8% had thyrotropin values > 30 mIU/L, whereas none of the infants in the chlorhexidine group had elevated thyrotropin values (p < 0.05). The elevated thyrotropin levels correlated positively with the area of disinfection. Elevated urine iodine levels were present reflecting an abnormally high iodine absorption. This study suggests that iodine absorption from topical iodine-containing antiseptics may cause disturbances in thyroid function test results in premature infants. We recommend that caution be exercised in the use of iodine-containing antiseptics in premature infants.

    In multiple gestation, premature rupture of fetal membranes (PROM) is an important risk factor for premature delivery and intrauterine infection. The incidence of PROM in twin gestations is threefold of that in singleton pregnancies. The incidence in triplets occurs even more frequently underlining the role of PROM as a leading cause of infant mortality and morbidity. Besides prematurity the complications of PROM include umbilical cord compression due to oligohydramnios, cord prolapse, placental abruption, and chorioamnionitis. Together with PROM, chorioamnionitis is held responsible for significant maternal and neonatal morbidity including endometritis and sepsis in the mother and early-onset sepsis, respiratory distress syndrome, inborn pneumonia, bronchopulmonary dysplasia, intraventricular hemorrhage, and periventricular white matter injury in the neonate. Furthermore, in twin gestations, PROM remains an independent risk factor for long-term neonatal care. An uncommon situation develops when in multiple gestation PROM affects only one of the fetuses. In such cases, the co-existence in the uterine cavity of the properly developing fetus(es) can be a challenge for the process of medical decision-making. In the present work, limited world literature on the topic was critically reviewed in search of the best possible recommendations for clinical management.

    Glycopeptide-resistant Enterococcus faecium has emerged as an important nosocomial pathogen with limited therapeutic options. Here we report the successful treatment of glycopeptide-resistant E. faecium infection in two very low birth weight premature infants with the new oxazolidinone linezolid. Treatment with linezolid at a dosage of 10 mg/kg every 8 h intravenously for a duration of 16 days and 14 days, respectively, was well tolerated and led to complete clinical recovery and clearance of the organism from all body sites. The two cases support the clinical efficacy and safety of linezolid in very low birth weight premature neonates with glycopeptide-resistant E. faecium infections.

    Plasma oestradiol 17β and progesterone levels in 11 patients admitted to hospital for threatened premature labour of unknown aetiology were compared with those of women at similar stages of gestation whose pregnancy was normal. Oestradiol levels in the study group were slightly higher than in the normal controls but their progesterone levels were significantly lower. This progesterone deficiency increased the oestradiol/progesterone ratio in the study group patients, and it increased still more as the progesterone withdrawal continued during premature labour. Since uterine activity during pregnancy is regulated by a balanced action of several factors a deficiency in progesterone, an opponent of uterine activity, creates a regulatory imbalance which, if uncorrected, provokes premature labour. An increase in uterine volume stimulates uterine activity, and the present study reinforced our previous conclusion that the uterine-volume/plasma-progesterone ratio is a more accurate measure of the state of regulatory balance than the progesterone level alone. The cause of the progesterone deficiency in these cases remains unexplained, but we suggest that placental growth and function are contributory factors. We are investigating ways of correcting the resulting imbalance in the regulatory mechanism. PMID:4812406

    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.

  14. Human recombinant erythropoietin in the prevention and treatment of anemia of prematurity.

    PubMed

    Ohls, Robin K

    2002-01-01

    Human recombinant erythropoietin has been studied extensively as treatment for a variety of anemias. Since in vitro studies showed the primary etiology of the anemia of prematurity to be insufficient serum erythropoietin concentrations, clinical trials have evaluated the administration of human recombinant erythropoietin to preterm infants to treat this indication. These studies were followed by pharmacokinetic determinations in animal models and preterm infants, which revealed that preterm infants required greater doses of human recombinant erythropoietin because of a more rapid clearance and greater volume of distribution. Recent studies have focused on the administration of human recombinant erythropoietin in the first weeks of life to alleviate the anemia caused by excessive phlebotomy losses, and to prevent the anemia of prematurity. In addition, human recombinant erythropoietin has been tried clinically in a variety of neonatal populations in an attempt to decrease or eliminate transfusions. Although much information has been accumulated about the clinical use of human recombinant erythropoietin in preterm infants over the last 15 years, many questions remain unanswered. The evolution of clinical practice in the care of extremely low birthweight infants continues to affect the number of transfusions. It is likely that human recombinant erythropoietin administration in combination with instituting rigorous transfusion guidelines and decreasing phlebotomy losses will have the greatest impact in decreasing transfusion requirements in all preterm and term neonates, regardless of the etiology of their anemia.

    Objective. Current American retinopathy of prematurity (ROP) screening guidelines is imprecise for infants ≥ 30 weeks with birth weights between 1500 and 2000 g. Our objective was to evaluate a risk factor based approach for screening premature infants at low risk for severe ROP. Study Design. We performed a 13-year review from Intermountain Health Care (IHC) data. All neonates born at ≤32 weeks were reviewed to determine ROP screening and/or development of severe ROP. Severe ROP was defined by stage ≥ 3 or need for laser therapy. Regression analysis was used to identify significant risk factors for severe ROP. Results. We identified 4607 neonates ≤ 32 weeks gestation. Following exclusion for death, with no retinal exam or incomplete data, 2791 (61%) were included in the study. Overall, severe ROP occurred in 260 (9.3%), but only 11/1601 ≥ 29 weeks (0.7%). All infants with severe ROP ≥ 29 weeks had at least 2 identified ROP risk factors. Implementation of this risk based screening strategy to the IHC population over the timeline of this study would have eliminated screening in 21% (343/1601) of the screened population. Conclusions. Limiting ROP screening for infants ≥ 29 and ≤ 32 weeks to only those with clinical risk factors could significantly reduce screening exams while identifying all infants with severe ROP.

    We investigated the effect of gender on survival and short-term outcomes of extremely premature infants (≤27 weeks) born in Canada. The records of infants admitted between 2000 and 2005 to a neonatal intensive care unit participating in the Canadian Neonatal Network were reviewed for infant gender, birth weight, gestational age, outborn status, Score for Neonatal Acute Physiology II, and antenatal corticosteroid exposure. The following outcomes were recorded: survival at final discharge, necrotizing enterocolitis, bronchopulmonary dysplasia (BPD), intraventricular hemorrhage grade ≥3, retinopathy grade ≥3, days on ventilation, and length of hospital stay. Among 2744 extremely premature infants, 1480 (54%) were male and 1264 (46%) were female. Mean birth weight of female neonates was significantly lower at each week of gestational age. Although no significant difference in survival at discharge was found between genders overall, the prevalence of BPD, combined adverse outcomes, and mortality for infants born between 24 and 26 weeks were significantly higher in males. This study suggests that, in the postsurfactant era, males remain at higher risk of respiratory complications and may have higher mortality when born between 24 and 26 weeks of gestation.

    Premature neonates of very low birth weight (VLBW) whose treatment required the use of naso-gastric tube feeding were investigated. 10 infants suspected of having GERD (gastroesophageal reflux) received oral lansoprazole therapy by tube administration. 9 other infants formed a control group. In the treated group a fasting pH was determined before treatment and again after 7 days treatment. The control group was similarly assessed at an interval of 7 days. Despite acid reduction, the post-treatment pH mean of 1.31 would continue to pose a threat to the esophageal mucosa. The physiology of neonatal acid secretion is discussed to explain these findings.

    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.

    Prematurity is the leading cause of infant mortality worldwide. In developed countries, extremely preterm infants contribute disproportionately to both neonatal and infant mortality. Survival of this high-risk population has incrementally improved in recent years. Despite these improvements, approximately 1 in 4 extremely preterm infants dies during the birth hospitalization. Among those who survive, respiratory and other morbidities are common, although their effect on quality of life is variable. In addition, long-term neurodevelopmental impairment is a large concern for patients, clinicians and families. However, the interplay of multiple factors contribute to neurodevelopmental impairment, with measures that change over time and outcomes that can be difficult to define and predict. Understanding outcomes of extremely preterm infants can help better counsel families regarding antenatal and postnatal care and guide strategies to improve survival without morbidity. This review summarizes recent evidence to provide an overview into the short- and long-term outcomes for extremely preterm infants. PMID:26799967

    Objective: To describe the eruption chronology of the first deciduous teeth in premature infants with birth weight less than 1500g and to compare it according to gender and nutritional status at birth. Methods: Longitudinal study including 40 low birth weight premature infants of both genders. The tooth was considered erupted when the crown went through the gum and became part of the oral environment. The comparison of the eruption chronology in relation to gender and among children appropriate or small for gestational age was done by Student's t-test, being significant p<0.05. Results: The eruption of the first tooth (teeth) occurred, on average, with 11.0±2.1 months of chronological age and with 9.6±1.9 months corrected for prematurity. The first erupted teeth were the lower central incisors. The average eruption for males was 9.7±1.9 and, for females, 9.5±1.9 months, both corrected for prematurity (p=0.98). The average eruption in children with birth weight appropriate for gestational age was 10.1±1.4 months; for small for gestational age, it was 9.4±2.2, also corrected for prematurity (p=0.07). Conclusions: The average eruption age of the first teeth, corrected for prematurity, was 9.6 months. Sex and nutritional status at birth did not change the eruption chronology. PMID:24676185

    Nutritional quality during the first weeks of life can influence health during both infancy and adulthood. Exclusive long-term breast feeding is strongly recommended, particularly for infants at risk of allergy. It protects against gastrointestinal and respiratory infections, and has been shown to enhance cognitive and intellectual development. Breast-feeding is also associated with a lower risk of obesity and type 1 diabetes in infants and of cardiovascular disease in adults. Breast-feeding is rarely contraindicated. Multiple European and French guidelines and regulations govern the composition of infant formulas, which may be given during the first year of life when breast-feeding is unavailable. Hypoallergenic and soy-based formulas are not recommended for healthy infants.

    Late-onset circulatory dysfunction (LCD) is a phenomenon specific to premature infants and is characterized by sudden onset of hyponatremia, hypotension, oliguria and non-physiological weight gain, without an obvious cause, in premature infants after stabilization of circulation and respiration. The cause of LCD is not clear, but adrenal insufficiency in premature infants is a severe syndrome because steroid replacement therapy is often essential to treat the symptoms. We report a rare case of a premature infant who developed an LCD crisis the day after thyroxine replacement therapy. The female infant was born at 25 weeks of gestational age, weighing 672 g, and appeared to have hypothyroidism, with free T4 of 0.19 ng/dl and elevated TSH levels of 26.3 microIU/ml at Day 14. She developed an LCD crisis the day after starting thyroxine treatment. She received steroid replacement therapy for 4 weeks and her adrenal function progressively recovered. She also needed thyroxine supplementation for 13 weeks, which maintained her thyroid function as euthyroid. Because she exhibited cortisol insufficiency and thyroid hormone insufficiency, the antecedent thyroid hormone replacement may be responsible for the onset of LCD. We must consider monitoring adrenal function when starting thyroxine therapy in premature infants with hypothyroxinemia.

    Premature ejaculation (PE) is a frequent male sexual complaint that affects 20 to 30% of men. The exact aetiology is unknown: psychological/behavioristic and biogenic etiologies have been proposed. The introduction of selective serotonin reuptake inhibitors (SSRI) was revolutionary in the medical treatment of PE. However precautions should be taken because of potential adverse side effects. There is no clear consensus as to whether SSRI may represent an eventual cure of PE or will be required for life. The sexocorporal approach is an other treatment of PE, but convincing scientific treatment data are also lacking.

    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.

    Healthcare-associated infections are a major problem in newborn infants, considering their high morbidity, mortality, and long-term sequelae. In preterm infants, it has been shown that skin and gastrointestinal tract colonization undergoes variations compared to healthy term infants, and that preterm infants are more exposed to nosocomial microorganisms given their higher probability of being admitted to the neonatal intensive care unit where they are cared for. This document reviews normal colonization, the changes observed during hospitalization, prematurity, and the potential role of chlorhexidine in the prevention of resistant microorganism transmission, as well as its side effects in newborn infants admitted to the neonatal intensive care unit.

    Isotretinoin has been considered a unique drug for acne treatment. However, it is associated with numerous adverse effects. Isotretinoin can trigger premature ventricular contractions. This report describes a 33-year-old-woman who presented with palpitations for 1 week while undergoing 1-month isotretinoin treatment for mild-moderate facial acne. An electrocardiogram and Holter monitoring showed premature ventricular contractions during isotretinoin (Roaccutane, Roche) treatment. Isotretinoin-related premature ventricular contractions were strongly suggested in this case due to the existence of documented premature ventricular contractions on electrocardiograms and the disappearance of these premature ventricular contractions two weeks after termination of the treatment To the authors' knowledge, there has been 1 reported case of premature ventricular contractions linked to isotretinoin use; this report describes a second such case.

    Successful transition from intrauterine to extrauterine life involves significant physiologic changes. The majority of these changes occur relatively quickly during those first moments following delivery; however, transition for the extremely preterm infant occurs over a longer period of time. Careful assessment and perceptive interventions on the part of neonatal care providers is essential as the extremely preterm infant adjusts to life outside the womb. This article will focus on respiratory, cardiovascular, gastrointestinal, and neurologic transitional events experienced by the extremely premature infant.

    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

    Systemic fungal infection continues to be a major cause of mortality in extremely low-birth-weight premature infants. Amphotericin B has been recommended as the primary treatment; however, its use is limited due to drug-induced nephrotoxicity and amphotericin B-resistant candidemia. Caspofungin therapy was initiated in seven extremely premature infants at 23 and 24 weeks' gestation with persistent systemic candidiasis despite liposomal amphotericin B treatment. The gestational age was 23(+1)-24(+6) weeks, and birth weight was 530-825 g. Of the seven patients, the peripheral blood cultures of six patients were positive for Candida parapsilosis and one had positive culture for Candida albicans. The dosage of caspofungin was 2 mg/kg/day, and the mean treatment duration was 14 days. All of the persistent candidemia resolved on caspofungin therapy. There was no recurrent candidemia after discontinuing caspofungin. There were no adverse effects, hepatotoxicity, nephrotoxicity, anemia, or thrombocytopenia. Caspofungin successfully treated persistent candidemia in extremely premature infants at 23 and 24 weeks' gestational age.

  14. The low-birth-weight infant

    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.

  15. Premature ovarian insufficiency - fertility challenge.

    Premature ovarian insufficiency, defined as amenorrhea with estrogen deficiency in a woman younger than 40 associated with a serum follicle stimulating hormone (FSH) >35 mIU/mL, can be temporarily reversed with ovulation achieved resulting in live delivered pregnancies. Though this may occur spontaneously the frequency of ovulation can be considerably increased by various techniques of lowering the elevated serum FSH level and thus up-regulate down-regulated FSH receptors in the granulosa-theca cells. This can be accomplished by either suppressing FSH release from the pituitary by negative feedback through high dose estrogen or by suppressing FSH production by inhibiting the gonadotropin releasing hormone (GnRH) by either using GnRH agonists or antagonists. The estrogen method is the technique of choice because it is much less expensive than GnRH analogues, and helps stimulate cervical mucus and endometrial development. Ethinyl estradiol is the preferred estrogen because it does not contribute to the measurement of serum estradiol and thus allows proper monitoring of follicular maturation. Sometimes exogenous gonadotropins are needed as a boost but the dosage should be low so as not to down-regulate FSH receptors again. The technique is referred to as the FSH receptor restoration technique. Progesterone should be supplemented in the luteal phase. Physicians should be cognizant of trying to help prevent premature ovarian insufficiency by judiciously choosing less gonadotoxic cancer treatment alternatives that are equally efficacious. Also surgery for ovarian endometriomas should be performed only when absolutely necessary.

    Oral sucrose reduces pain during heel sticks and venipunctures in preterm infants, but no studies have been done to determine the effectiveness of sucrose during eye examinations for retinopathy of prematurity. Therefore, the purpose of this study was to determine the effectiveness of local anesthetic eye drops and a pacifier, plus repeated doses of 24% sucrose, to relieve pain associated with eye examinations for retinopathy of prematurity. In this double-blind randomized controlled trial, 30 preterm infants were randomly assigned to one of two treatments, in which they received either local anesthetic eye drops, a pacifier, plus three doses of sterile water or local anesthetic eye drops, a pacifier, plus three doses of 24% sucrose during the eye examination. Treatment effectiveness was determined using a validated infant pain measure, the Premature Infant Pain Profile (PIPP), which includes measures of facial expressions, heart rate, and oxygen saturation and takes behavioral state and gestational age into consideration. Data were collected before, during, and following an examination of the left eye. Statistically significant differences in mean PIPP scores were found between the sucrose and water groups during the left eye examination. The mean PIPP score was 8.8 for the sucrose group and 11.4 for the water group ( t = 2.87, p = .008 two-tailed). No significant differences were found in PIPP scores immediately following the procedure. Sucrose and a pacifier may be beneficial for minimizing pain during eye examinations in preterm infants and should be considered as a part of evidence-based guidelines for relieving pain during this procedure.

    Infants are vulnerable: their growth and their development depend largely on their nutritional status. It is important to propose for them an optimal food. The human milk is unquestionably the best choice for the infant. When breastfeeding is not possible, the choice of the milk is made among hundreds of formulas for infants. They are regulated by a European directive. The healthcare professionals have to recommend as often as possible an infant formula: low protein content, predominance of whey proteins, enrichment with long chain fatty acids, lactose, addition of pre- or probiotics. The formulas for specific indications will be recommended in case of particular situations after verification that the complaints (constipation, regurgitations, stomach pains) cannot be corrected by simple dietary measures (increasing of the intakes of meals with a concomitant reduction of the volume of the meals). The food diversification is recommended between 17 and 26 weeks according to the neuromuscular capacities of the infant. These meals must be presented with a spoon to assure a sufficient nutritional intake. In Belgium, the use is to begin with fruits. One should avoid adding biscuits or sugar. The meal of vegetables will be introduced a little later. It should consist of starchy foods, vegetables with some fat to which the meat will be added. Numerous foods (biscuits, croissants and similar products, chips) should never be part of the ordinary menu, but should be reserved for particular occasions. The education of the children should begin from this age on.

    Resection of large sacrococcygeal teratomas (SCT) in neonates can pose many anesthetic challenges. The pathophysiology of the SCT determines the varying management. We present a case report of a 34-week newborn with a massive Altman type 3 SCT. The surgery was delayed 2 days because of hyperkalemia; however, as a result of continued tumor lysis the patient's condition had worsened with little improvement of the potassium level. During the surgery, the patient had issues of bleeding needing massive transfusion. Ventilation was also difficult at times because of the massive tumor resting on the chest, resulting in respiratory acidosis. We also had difficulty in maintaining the temperature. This patient did well after the surgery and was discharged home. We address here the anesthetic issues involved in the perioperative care management of a premature infant with a massive SCT.

    Retinopathy of prematurity (ROP) is a complex disease with a multifactorial pathogenetic cascade that is still only partially understood. Important pathogenetic factors are gestational age at birth and birth weight. Potent postnatal factors are exposure to supplemental oxygen, slow weight gain and expression of angiogenic growth factors. Some of these crucial aspects of ROP pathogenesis will be discussed in this article and put into clinical context. With the introduction of intravitreal anti-VEGF (vascular endothelial growth factor) treatment into ROP therapy, the pathomechanistic role of VEGF in ROP deserves a special focus. Apart from VEGF, other factors will be discussed that may precede VEGF upregulation and thus may represent targets for an earlier and potentially protective intervention. Among these insulin-like growth factor 1 (IGF-1) appears to be most prominent. Finally, factors such as postnatal weight gain will be discussed in light of their potential role as screening parameters and their ability to predict ROP severity.

    This review shows the results of the various studies concerning the protocols applied to the women presenting a premature ovarian failure. Will be thus analyzed the natural cycles (or semi-natural), the increase in the dose of gonadotrophins, the clomiphene citrate and the anti-aromatases, the protocols with GnRH agonists long, short, stop or microdoses, the protocols with GnRH antagonists and the adjuvant treatments: aspirin, nitric oxyde, recombinant LH recombining, growth hormone and androgens. The interest of several protocols is to collect a sufficient number of oocytes (and thus of embryos to be transferred), making it possible to obtain reasonable rates of pregnancy. However, it arises that the rates of pregnancy observed among these women depend not only on their ovarian reserve and their age, but are also function of the type of infertility, of the cycle number and the uterus.

    Objective Evaluate physiologic and behavioral pain responses of premature infants following instillation of mydriatic eye drops for ROP examinations. While burning and stinging occurs in older patients, the infant pain response is not well characterized. Study Design Vital sign and video monitor recorded infant responses before, during, and after mydriatic (tropicamide 1%, phenylephrine 2.5%) administration upon first ROP exam. Two masked observers graded Premature Infant Pain Profile (PIPP) scores immediately prior and following eye drop administration. Scores <7 indicate no/minimal pain, 7-12 slight/moderate, >12 severe. Results Twenty infants had mean pre-mydriatic PIPP score 3.6 (SD 1.6), mean post-mydriatic score 5.7 (SD 3.4), mean change 2.1 (SD 3.4)(p=0.01). One (5%) had pre-mydriatic PIPP score ≥7, seven (35%) post scores ≥7 (p=0.07) with one >12. Conclusions Mydriatic drops cause a clinically significant pain response in one third of infants. Non-pharmacologic supportive measures are recommended for all infants until predictive factors are defined. PMID:23238569

    Background This study aimed to evaluate the radiation dose received by premature neonates using diagnostic radiographies. Methods This cross-sectional study was conducted on 116 premature neonates with gestational age from 25 to 37 weeks; with the diagnosis of neonatal respiratory distress syndrome (NRDS) and tachypnea, they were admitted to a neonatal intensive care unit (NICU) at Ahvaz Imam Khomeini Hospital in 2015. For assessing the dose received, the model GR-200 thermoluminescent dosimeter (TLD) was used. For each premature neonate under radiation, three TLDs separately (one for each) were placed on surfaces of Ch1, T1, and G1 (chest, thyroid, and gonad of first newborn, respectively). Moreover, for the adjacent neonate at a distance of 60 - 100 cm, two TLDs were laid in the surfaces of T2 and G2 (thyroid and gonad of second newborn, respectively). The dose received by TLDs for any baby and the adjacent neonate under the entrance surface dose (ESD) was estimated. Results The mean of neonates’ weight under study was 1,950.78 ± 484.9 g. During the hospitalization period, minimum one and maximum three radiographies were done for any premature neonate. The doses received in the premature neonates to Ch1, T1 and G1 were 0.08 ± 0.01, 0.06 ± 0.01, and 0.05 ± 0.01 mSv, respectively and for adjacent infants for T2 and G2 were 0.003 ± 0.001 and 0.002 ± 0.0009 mSv, respectively. Conclusions In the study, radiation dose received by organs at risk of premature neonates was lower than the international criteria and standards, therefore, also due to the lack of radiation damage threshold, to limit collimator, and the use of the proper filtration, kilovoltage and time during radiography of premature neonates are recommended.

    Currently, there are enough financial resources in industrial most developed countries to provide quality health care to the risk population of premature children. Neonatological units are equipped with state-of-the-art technological background, and highly qualified personnel are employed at the units. This as well allows providing optimum care of extremely immature newborns. ROP prevalence in these countries reaches approximately 5-8%. Today, a boom of surviving premature newborns can be seen in countries with medium-developed economy. Nevertheless, limited financing resources do not allow for standard high-level care. In such countries, the prevalence reaches up to 30%. In this respect, the "third ROP epidemic" is mentioned. Birth weight and gestational age parameters achieve significantly lower values in ROP-infants than in those not affected by the disease. Higher number of surviving immature newborns correlates with an increased risk of advanced ROP stages occurrence, while the frequency and degree of the disease are of inverse nature to the gestational age and birth weight (Tab. 1, Ref. 39).

    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.

    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

    Preterm infants are highly susceptible to ischemic damage. This damage is most obvious in the brain, retina, and gastrointestinal tract. Studies focusing on the rheological properties of premature red blood cells (pRBCs) have consistently shown minimal or no RBC aggregation. Previously, measurements of pRBC aggregation kinetics indicated that specific plasma properties are responsible for the decreased RBC aggregation observed in the neonates, but that their specific RBC properties do not affect it. However, the strength of interaction in the pRBC aggregates as a function of medium composition has not been tested. In our previous research, we described clinically relevant parameters, that is, the aggregate resistance to disaggregation by flow. With the help of a cell flow property analyzer (CFA), we can monitor RBC aggregation by direct visualization of its dynamics during flow. We used the CFA to examine pRBC (from 9 premature babies) in the natural plasma and in PBS buffer supplemented with dextran (500 kDa) to distinguish between RBC intrinsic-cellular and plasma factors. pRBCs suspended in the native plasma showed minimal or no aggregation in comparison to normal adult RBC. When we transferred pRBCs from the same sample to the dextran solution, enhanced resistance to disaggregation by flow was apparent.

    Even though Costa Rica is underdeveloped economically, life expectancy has been increasing over the past decade and the illiteracy rate was only 7% in 1984. Infant mortality rates have plummeted since 1972 when the 1st national health plan and social security were instituted (pre-1972: 2.3% annual reduction in infant mortality; 1972-1980: 13% decline annually). Decreased risk in the 1st postnatal month of life was responsible for 34% of the decrease from 1972-1980. Control of disease, especially diarrhea and acute respiratory infection, accounted for most of the decline (51%). Immunizations accounted for 8%, prevention of infectious diseases for 10%, control of malnutrition for 5%, and control of death due to premature birth for 14% of the decrease in mortality. Infant death due to pregnancy and delivery complications and congenital defects did not decrease during this period. Socioeconomic conditions normally influence survival rates strongly, but socioeconomic change in Costa Rica during 1970-1980 accounted for only 1/3 of the reduction in infant mortality. These improvements included an increase in the number of educated women, economic growth and decline in fertility (a decrease from 7.6 to 3.4 births between 1960-1980). The majority of the reduction stemmed from utilization of family planning techniques and the reduction of health risk factors. By 1980, the health program initiated in the 1970's provided primary care to 60% of the population, immunized 95% of the children against poliomyelitis, diptheria, pertussis, tetanus, and measles, and by 1984, provided almost all households with a sewage system. Analyses of the impact of socioeconomic development, fertility regulation, hospital care, outpatient services, and primary health care on infant mortality showed that, before 1970, those areas with better economies had a lower mortality rate, and after 1970, the economy and mortality rate had become independent variables.

    Among obstetricians and neonatologists in administrative roles in New York City hospitals, a survey was initiated to compare the physicians' definitions of live birth and fetal death, the gestational age at which they consider infants viable, and the resuscitation practices of the neonatologists. The target survey population was 34 neonatologists, and 39 obstetricians representing 41 of the City's 43 maternity hospitals. A telephone survey was used to gather qualitative data from the physicians regarding their definitions of live birth, fetal death, and viability, and their practices regarding extremely premature births. Surveys were completed for 58 physicians, a response rate of 79% (94% for neonatologists and 67% for obstetricians). Physicians' definitions of live birth and fetal death varied, with almost a third (29%) of physicians including gestational age as part of their live birth criteria. Most of the physicians (90%) consider infants born at ≥23 weeks gestation viable. Most neonatologists (97%) said they always resuscitate infants born at ≥23 weeks gestation, and most (94%) said they would never resuscitate infants born at <20 weeks gestation. For infants born at 20-22 weeks gestation, there were differences in resuscitation practices. There is a gap between clinical practices and reporting requirements for live birth and fetal death. Whereas reporting requirements are based on definitions of live birth and fetal death, physicians make resuscitation and other clinical decisions regarding extremely premature infants based on definitions of viability.

  11. Peripheral arterial chemoreceptors and sudden infant death syndrome.

    PubMed

    2007-07-01

    Sudden infant death syndrome (SIDS) is the major cause of death in infants between 1 month and 1 year of age. Two particular concerns are that (1) premature or low birth weight (<2500-g) infants have a 2- to 40-fold greater risk of dying of SIDS (depending on the sleep position) than infants born at term and of normal birth weight, and that (2) the proportion of premature infants dying of SIDS has increased from 12 to 34% between 1988 and 2003. Hypo- and hypersensitivity of peripheral arterial chemoreceptors (PACs) may be one biological mechanism that could help to explain the epidemiological association between the increased incidence of SIDS in formerly premature infants. Because premature infants are often exposed to the extremes of oxygen stress during early postnatal development, they are more likely to have a maladaptive response of PACs later in their lives. As the first line of defense that mediates an increase in ventilation to a hypoxic challenge during wakefulness and sleep, PACs also mediate arousal responses during sleep in response to an asphyxial event that is often associated with upper airway obstruction. In most mammalian species, PACs are not fully developed at birth and thus are vulnerable to plasticity-induced changes mediated by environmental exposures such as the extremes of oxygen tension. Hypoxic or hyperoxic exposure during early postnatal development can lead to hyposensitive or hypersensitive PAC responses later in life. Although baseline chemoreceptor activity may not be the cause of an initial hypoxic or asphyxial event, the level of peripheral chemoreceptor drive does modulate the (1) time to arousal, (2) resumption of airflow during airway obstruction, (3) escape behaviors during rebreathing, and (4) cardiorespiratory responses that result from activation of the laryngeal chemoreflex. The laryngeal chemoreflex can be stimulated by reflux of gastric contents above the upper esophageal sphincter, or an increase in nasopharyngeal

    Objectives Laser photocoagulation surgery is a routine treatment for threshold retinopathy of prematurity (ROP). However, little is known about which anaesthesia protocols provide efficient pain control while minimising exposure risk to vulnerable infants. In this study, therefore, we assessed the efficacy and tolerability of multiple anaesthesia techniques used on premature infants during laser therapy. Design and main outcome measures Anaesthesia modalities consisted of topical eye drops anaesthesia, general anaesthesia and intravenous fentanyl sedation with mechanical ventilation. Laser treatment efficacy and detailed operative information were retrospectively and consecutively analysed. Cardiorespiratory stability was assessed and compared. The Neonatal Pain Agitation and Sedation Scale (N-PASS) was used to evaluate tolerability in infants that underwent intravenous fentanyl sedation. Results 97 cases of prematurity were included in this study. In 94/97 (96.9%) cases, vascular proliferation regressed. In the topical anaesthesia groups, the ophthalmologist needed 12–16 min more to complete the treatment. During the 3 postoperative days, topical anaesthesia demonstrated the greatest instability; 4/31 (12.90%) infants in this group suffered from life threatening events requiring resuscitation. The only instability observed in general anaesthesia and fentanyl sedation was attributed to difficulty in extubating within 24 hours after surgery. During laser therapy, the N-PASS score increased to 1.8 in the fentanyl sedation group. Conclusions Topical anaesthesia was associated with more cardiorespiratory instability during ROP laser treatment. While general anaesthesia and fentanyl sedation had similar postoperative cardiorespiratory results, the latter demonstrated acceptable pain stress control. However, the difficulty of weaning off mechanical ventilation in some cases after surgery needs to be addressed in future studies. PMID:28119385

    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.

  14. Psychosexual therapy for premature ejaculation

    PubMed Central

    2016-01-01

    Premature ejaculation (PE) is a male sexual dysfunction that creates considerable anguish for the man, his partner and their relationship. PE is not one disorder but includes the four subtypes (lifelong, acquired, natural and subjective) each with unique psychological concerns and issues. Psychological treatment for men and couples with PE addresses sexual skills/techniques but also focuses on issues of self-esteem, performance anxiety and interpersonal conflict. The outcome studies for psychotherapy alone are difficult to interpret and compare because of poor methodological design (lack of control groups, small sample size, poor outcome measures and lack of follow-up). However, the few studies that surmount these methodological hurdles suggest that psychological intervention offers men and couples a promising treatment option. Combination pharmaco- and psychotherapy is the most promising intervention for lifelong and acquired PE and offers superior efficacy to drug alone. This is because men and couples learn sexual skills, address the intrapsychic, interpersonal and cognitive issues that precipitate and maintain the dysfunction. PMID:27652220

    Vast advances have occurred over the past decade with regards to understanding the epidemiology, pathophysiology and management of premature ejaculation (PE); however, we still have much to learn about this common sexual problem. As a standardized evidence-based definition of PE has only recently been established, the reported prevalence rates of PE prior to this definition have been difficult to interpret. As a result, a large range of conflicting prevalence rates have been reported. In addition to the lack of a standardized definition and operational criteria, the method of recruitment for study participation and method of data collection have obviously contributed to the broad range of reported prevalence rates. The new criteria and classification of PE will allow for continued research into the diverse phenomenology, etiology and pathogenesis of the disease to be conducted. While the absolute pathophysiology and true prevalence of PE remains unclear, developing a better understanding of the true prevalence of the disease will allow for the completion of more accurate analysis and treatment of the disease.

PE is not one disorder but includes the four subtypes (lifelong, acquired, natural and subjective) each with unique psychological concerns and issues. Psychological treatment for men and couples with PE addresses sexual skills/techniques but also focuses on issues of self-esteem, performance anxiety and interpersonal conflict. The outcome studies for psychotherapy alone are difficult to interpret and compare because of poor methodological design (lack of control groups, small sample size, poor outcome measures and lack of follow-up). However, the few studies that surmount these methodological hurdles suggest that psychological intervention offers men and couples a promising treatment option. Combination pharmaco- and psychotherapy is the most promising intervention for lifelong and acquired PE and offers superior efficacy to drug alone. This is because men and couples learn sexual skills, address the intrapsychic, interpersonal and cognitive issues that precipitate and maintain the dysfunction.

  17. The epidemiology of premature ejaculation

    Vast advances have occurred over the past decade with regards to understanding the epidemiology, pathophysiology and management of premature ejaculation (PE); however, we still have much to learn about this common sexual problem. As a standardized evidence-based definition of PE has only recently been established, the reported prevalence rates of PE prior to this definition have been difficult to interpret. As a result, a large range of conflicting prevalence rates have been reported. In addition to the lack of a standardized definition and operational criteria, the method of recruitment for study participation and method of data collection have obviously contributed to the broad range of reported prevalence rates. The new criteria and classification of PE will allow for continued research into the diverse phenomenology, etiology and pathogenesis of the disease to be conducted. While the absolute pathophysiology and true prevalence of PE remains unclear, developing a better understanding of the true prevalence of the disease will allow for the completion of more accurate analysis and treatment of the disease.

    The frequency of low birth weight (less than or equal to 2500 g) and of preterm birth (less than 37 weeks) was studied in 22,761 single live births in relation to maternal employment, taking account of 11 nonoccupational confounding factors. There was some increase of low statistical significance in both types of prematurity in service and manufacturing sectors of industry. A substantial excess of preterm births was seen in women employed in food and beverage service (O/E = 1.29, p = 0.03) and psychiatric nursing (O/E = 2.47, p less than 0.01) and of low birth weight in food and beverage service (O/E = 1.30, p = 0.02), in chambermaids and cleaners (O/E = 1.42, p = 0.03), and in those employed in the manufacture of metal and electrical and certain other goods (O/E = 1.57, p less than 0.01). Heavy lifting and long hours of work were consistently related to both outcomes, changing shift work less consistently. Noise was associated with low birth weight in the health and manufacturing sectors. The findings of this study are unlikely to have resulted from subject or observer bias but the role of unidentified factors related to selection for work are difficult to assess. PMID:3342188

    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.

    Objective Exposure to pollutants during pregnancy has been related to adverse birth outcomes. LBW can give rise to lifelong impairments. Prematurity is the leading cause of LBW, yet few studies have attempted to analyse how environmental factors can influence LBW in infants who are not premature. This study therefore sought to analyse the influence of air pollution, noise levels and temperature on LBW in non-premature births in Madrid during the period 2001–2009. Methods Ecological time-series study to assess the impact of PM2.5, NO2 and O3 concentrations, noise levels, and temperatures on LBW among non-premature infants across the period 2001–2009. Our analysis extended to infants having birth weights of 1,500 g to 2,500 g (VLBW) and less than 1,500 g (ELBW). Environmental variables were lagged until 37 weeks with respect to the date of birth, and cross-correlation functions were used to identify explaining lags. Results were quantified using Poisson regression models. Results Across the study period 298,705 births were registered in Madrid, 3,290 of which had LBW; of this latter total, 1,492 were non-premature. PM2.5 was the only pollutant to show an association with the three variables of LBW in non-premature births. This association occurred at around the third month of gestation for LBW and VLBW (LBW: lag 23 and VLBW: lag 25), and at around the eighth month of gestation for ELBW (lag 6). Leqd was linked to LBW at lag zero. The RR of PM2.5 on LBW was 1.01 (1.00 1.03). The RR of Leqd on LBW was 1.09 (0.99 1.19)(p<0.1). Conclusions The results obtained indicate that PM2.5 had influence on LBW. The adoption of measures aimed at reducing the number of vehicles would serve to lower pregnant women's exposure. In the case of noise should be limited the exposure to high levels during the final weeks of pregnancy. PMID:27788159

    Background Norovirus is an important cause of nonbacterial acute gastroenteritis in all ages. Atypical courses are described. Clinical symptoms are diarrhea, vomiting, nausea, abdominal cramps, fever and malaise. Apart from three recent short reports we describe for the first time an outbreak of norovirus in a tertiary Neonatal Intensive Care Unit. Findings The typical symptoms of norovirus infection are in part also seen in premature born infants but with a different pattern and a huge variety of clinical courses. Vomiting is not the main symptom of norovirus infection in premature infants but distended abdomen and other symptoms such as apnea, gastric remainders or sepsis like appearance. The course in premature born patients could be explained by an immunocompromised mice model. Extensive hygienic measures were necessary to control the outbreak without closing the Neonatal Intensive Care Unit. Conclusion Norovirus infection in premature infants shows an impressive pattern of a wide variety of clinical courses. Only the consequent use of different hygienic pattern can lead to elimination of norovirus. PMID:19490612

    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.

    Retinopathy of prematurity (ROP), a retinal vascular disease of premature infants, continues to be a major cause of preventable childhood blindness all over the world. The incidence of ROP varies among countries, being influenced by the quality of the level of neonatal intensive care. Here, we discuss the potential treatments that are now available or will soon or probably be available for ROP. Although ablation of the avascular retina with laser photocoagulation remains the current gold standard and well established therapy for ROP, some new therapeutic options including angiostatic therapies are being explored based on our knowledge of the pathophysiology of the ROP and complications and efficacy of laser treatment. However, prevention of the development of severe ROP and screening for ROP seem to be the best strategy in avoiding visual impairment caused by ROP in premature infants. New therapeutic interventions including vascular endothelial growth factor antibody administration, gene therapy and supplemental therapies should be supported with evidence-based data for the treatment of ROP.

  4. 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.

    This study examined the associations of testosterone and cortisol levels with maternal depressive symptoms and infant socioemotional (SE) problems that are influenced by infant gender. A total of 62 mothers and their very-low-birth weight (VLBW) infants were recruited from a neonatal intensive care unit at a tertiary medical center in the southeast United States. Data were collected at three time points (before 40 weeks' postmenstrual age [PMA] and at 3 months and 6 months of age corrected for prematurity). Measures included infant medical record review, maternal interview, biochemical assays of salivary hormone levels in mother-VLBWinfant pairs, and standard questionnaires. Generalized estimating equations with separate analyses for boys and girls showed that maternal testosterone level was negatively associated with depressive symptoms in mothers of boys, whereas infant testosterone level was negatively associated with maternal report of infant SE problems in girls after controlling for characteristics of mothers and infants and number of days post birth of saliva collection. Not surprisingly, the SE problems were positively associated with a number of medical complications. Mothers with more depressive symptoms reported that their infants had more SE problems. Mothers with higher testosterone levels reported that girls, but not boys, had fewer SE problems. In summary, high levels of testosterone could have a protective role for maternal depressive symptoms and infant SE problems. Future research need to be directed toward clinical application of these preliminary results.

    Rationale: Bronchopulmonary dysplasia is the most common morbidity of prematurity, but the validity and utility of commonly used definitions have been questioned. Objectives: To compare three commonly used definitions of bronchopulmonary dysplasia in a contemporary prospective, multicenter observational cohort of extremely preterm infants. Methods: At 36 weeks postmenstrual age, the following definitions of bronchopulmonary dysplasia were applied to surviving infants with and without imputation: need for supplemental oxygen (Shennan definition), National Institutes of Health Workshop definition, and “physiologic” definition after a room-air challenge. Measurements and Main Results: Of 765 survivors assessed at 36 weeks, bronchopulmonary dysplasia was diagnosed in 40.8, 58.6, and 32.0% of infants, respectively, with the Shennan, workshop and physiologic definitions. The number of unclassified infants was lowest with the workshop definition (2.1%) and highest with the physiologic definition (16.1%). After assigning infants discharged home in room air before 36 weeks as no bronchopulmonary dysplasia, the modified Shennan definition compared favorably to the workshop definition, with 2.9% unclassified infants. Newer management strategies with nasal cannula flows up to 4 L/min or more and 0.21 FiO2 at 36 weeks obscured classification of bronchopulmonary dysplasia status in 12.4% of infants. Conclusions: Existing definitions of bronchopulmonary dysplasia differ with respect to ease of data collection and number of unclassifiable cases. Contemporary changes in management of infants, such as use of high-flow nasal cannula, limit application of existing definitions and may result in misclassification. A contemporary definition of bronchopulmonary dysplasia that correlates with respiratory morbidity in childhood is needed. Clinical trial registered with www.clinicaltrials.gov (NCT01435187).

    Chronic kidney disease (CKD) shares many phenotypic similarities with other chronic diseases, including heart failure, chronic obstructive pulmonary disease, HIV infection and rheumatoid arthritis. The most apparent similarity is premature ageing, involving accelerated vascular disease and muscle wasting. We propose that in addition to a sedentary lifestyle and psychosocial and socioeconomic determinants, four major disease-induced mechanisms underlie premature ageing in CKD: an increase in allostatic load, activation of the 'stress resistance response', activation of age-promoting mechanisms and impairment of anti-ageing pathways. The most effective current interventions to modulate premature ageing-treatment of the underlying disease, optimal nutrition, correction of the internal environment and exercise training-reduce systemic inflammation and oxidative stress and induce muscle anabolism. Deeper mechanistic insight into the phenomena of premature ageing as well as early diagnosis of CKD might improve the application and efficacy of these interventions and provide novel leads to combat muscle wasting and vascular impairment in chronic diseases.

    Premature rupture of membranes is defined as expulsion of the amniotic liquid occurring at least 1 hour before initiation of uterine contractions and without apparent cervical changes. According to the literature, premature rupture of membranes occurs in 2-15% of all pregnancies, with an average of 10%. The etiology is considered multifactorial, and treatment remains controversial. A retrospective review was conducted to determine the occurrence of maternal or perinatal morbidity and mortality in 230 cases of premature rupture of membranes in a social security hospital in Santo Domingo, Dominican Republic, observed between 1983-88. Premature rupture occurred in 3.5% of cases according to the records. 37.4% of affected mothers were 21-25 years old and 69.6% were 21.30. 62.9% of the women were nulliparas. 2.2% had had no prenatal care, 59.1% had insufficient prenatal care, defined as 1-5 visits and only 36.1% had 6 or more visits. 81.3% of ruptures occurred at 37-42 weeks of gestation. In 64.8% of cases the pregnancy was terminated within 1-24 hours and 35.2% were considered prolonged. Prematurity and low birth weight was the most common perinatal disorders, affecting 10.9%. Respiratory difficulty syndrome affected 4.3%. 60% of infants with respiratory problems were born at less than 37 weeks gestation. Neonatal sepsis occurred in 3% of cases and prolapse of the umbilical cord in 1.3%. Perinatal mortality averaged 2.6%. Prematurity was a factor in all cases. Respiratory distress syndrome and neonatal sepsis were each present in 50% of cases and hyperbilirubinemia in 33%. 8.7% of the mothers developed chorioamnionitis. Only 23.9% terminated their pregnancies spontaneously. Oxytocin was used to induce labor in 30.4% and cesareans were performed in 44.8%.

    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

    AIMS—To examine the effects of light on retinal development and function in preterm infants as measured by the electroretinogram (ERG). Secondary outcomes included visual acuity testing, the incidence of retinopathy of prematurity, and general wellbeing, reflected in feeding tolerance, rate of weight gain, and length of hospital stay.
METHODS—Eligibility criteria for enrolment were birthweight ⩽ 1250 g and gestational age ⩽ 31 weeks. Sixty one infants were randomly allocated by 6 hours after birth to a control or treatment group which wore 97% light filtering goggles for a minimum of four weeks or until the infant reached 31 weeks postmenstrual age.
RESULTS—There were no significant differences between the two groups in the numbers of electroretinograms performed at 36 weeks of postmenstrual age. Although the sample size was not large enough to exclude clinically important differences in secondary outcomes, no significant differences were observed between the groups in visual acuity testing at 4-6 months corrected age, incidence of retinopathy of prematurity, weight gain, or length of stay.
CONCLUSION—These data support the safety and feasibility of this intervention. A much larger study will be needed to determine whether light reduction to the eyes of very low birthweight infants will reduce the incidence of retinopathy of prematurity or enhance general wellbeing.

    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.

    The results of ligation of a patent ductus arteriosus in 30 premature neonates with a very low birth weight were analysed. The mean gestational age at birth was 27 weeks and the mean weight 811 g. Attempted closure of the ductus with indomethacin in 19 infants failed, though there was temporary closure in nine. Congestive heart failure was present in 29 and respiratory distress in 22 patients. Endotracheal intubation with assisted ventilation was necessary in all cases. The mean age at operation was 13.5 days and ductal ligation was performed in the intensive care unit under local anaesthesia supplemented with pancuronium and pethidine. There were no intraoperative deaths, but five infants died in hospital. There were seven late deaths. Eighteen survivors have been followed for a mean of 26.5 months. Early ligation of a patent ductus arteriosus in premature infants with a very low birth weight improved the cardiorespiratory state. Long term follow up showed good clinical progress in two thirds of the surviving group. PMID:4035621

    Pulmonary interstitial emphysema (PIE) contributes to worsening respiratory status in already compromised premature infants. Various treatments for PIE include high-frequency ventilation, postural therapy, pneumonectomy or lobectomy and selective bronchial intubation. While right main stem bronchus intubation is easy to perform at the bedside for treatment of PIE in the left lung, left main stem bronchus intubation for the treatment of right-sided PIE remains challenging and the technique was rarely reported and poorly described. In this case report, we revisit this procedure and describe successful treatment of right lung PIE with hyperinflation by selective left main stem intubation at 2 weeks of life in a 24-week-old premature infant who had respiratory distress syndrome and pulmonary hemorrhage. A detailed description is given to allow clinical bedside replication following specific anatomic landmarks.

    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

Strategies employing auditory stimulation demonstrate blood-oxygen-level-dependent (BOLD) activation in preterm infants as young as 33 weeks' gestational age, and reliable BOLD signal in response to visual stimulation occurs at term-equivalent age. Strategies based on fMRI are particularly suited to the study of language and memory, and emerging data are likely to provide insights into perplexing reports that have demonstrated improving cognitive scores but persistent volumetric and microstructural changes in frontotemporal language systems in the prematurely born. Even when sex, gestational age and early medical and environmental interventions are taken into account, fMRI data from several investigators suggest the engagement of alternative neural networks for language and memory in the developing preterm brain.

    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.

    Introduction Invasive Candida infections are a leading cause of mortality and morbidity in neonatal intensive care units (NICUs). Micafungin is a promising therapeutic option for treatment of invasive fungal infections in infants given its safety profile in older children and adults. Understanding micafungin safety in infants is particularly important because antifungals are most often used in premature infants with multiple underlying medical conditions in a critical care setting. Areas covered This article reviews the literature evaluating the safety profile of micafungin in infants and offers recommendations for optimal dosing for treatment of invasive candidiasis in the NICU setting. The review was performed using a Medline search in September 2010 for related articles from 1990 to present with the Mesh related terms ‘micafungin’ and ‘safety’ in combination with the free words ‘antifungal’, ‘candidiasis’, ‘drug toxicity’, ‘infant, premature’, and ‘infant, newborn’. Expert opinion Despite the limitations of the existing literature, we believe micafungin dosing of 10 mg/kg/day for all term and preterm infants is a viable treatment option in the NICU setting for management of invasive candidiasis. Although the number of infants for whom safety data are reported is small, higher doses of micafungin appear safe and well-tolerated in this population. PMID:21226655

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

    Objective: Infection with respiratory syncytial virus (RSV), which causes lower respiratory tract infections, is the leading cause of hospitalization among children <1 year old in the United States. Risk factors for RSV hospitalization include premature birth and younger chronologic age, along with several comorbid conditions. However, in terms of RSV hospitalization costs, premature infants are rarely studied separately from full-term infants. The objective of this study is to describe the cost and severity of RSV hospitalizations among preterm and full-term infants without chronic lung disease or other high-risk conditions. Study Design: This analysis used Truven Health Market Scan Multi-State Medicaid and Commercial Claims and Encounters databases, which contain a combined 4 million births from 2003 to 2013. Infants with comorbid conditions associated with increased risk for RSV infection were excluded. Infants were classified as preterm (<29, 29−30, 31−32, 33−34 and 35−36 weeks' gestational age (wGA)) or full term based on diagnostic coding. Health-care claims during the first year of life were evaluated for RSV hospitalizations, defined as inpatient claims with a diagnosis code for RSV in any position. Costs of RSV hospitalizations were captured and reported in 2014 USD. Inpatient claims for RSV hospitalizations were evaluated for the presence of codes indicating admission to the intensive care unit (ICU), use of mechanical ventilation (MV) and length of stay. These three measures were used to describe hospital severity. Chronologic age at the time of RSV hospitalization was also captured. Data were summarized and no statistical comparisons were conducted. Results: There were 1 683 188 infants insured through Medicaid and 1 663 832 infants insured through commercial plans born from 1 July 2003 to 30 June 2013. Of those, 10.8 and 8.8% in each database, respectively, were born prematurely. There were 29 967 Medicaid-insured infants and 16 310

    Candida is a leading cause of late-onset sepsis in premature infants and is thought to invade the host via immature or damaged epithelial barriers. We previously showed that the hyphal form of Candida albicans invades and causes damage to premature intestinal epithelial cells (pIECs), whereas the non-hyphal Candida parapsilosis, also a fungal pathogen of neonates, has less invasion and damage abilities. In this study, we investigated the potential for C. parapsilosis to modulate pathogenic interactions of C. albicans with the premature intestine. While a mixed infection with two fungal pathogens may be expected to result in additive or synergistic damage to pIECs, we instead found that C. parapsilosis was able to protect pIECs from invasion and damage by C. albicans. C. albicans-induced pIEC damage was reduced to a similar extent by multiple different C. parapsilosis strains, but strains differed in their ability to inhibit C. albicans invasion of pIECs, with the inhibitory activity correlating with their adhesiveness for C. albicans and epithelial cells. C. parapsilosis cell-free culture fractions were also able to significantly reduce C. albicans adhesion and damage to pIECs. Furthermore, coadministration of C. parapsilosis cell-free fractions with C. albicans was associated with decreased infection and mortality in zebrafish. These results indicate that C. parapsilosis is able to reduce invasion, damage, and virulence functions of C. albicans. Additionally, the results with cellular and cell-free fractions of yeast cultures suggest that inhibition of pathogenic interactions between C. albicans and host cells by C. parapsilosis occurs via secreted molecules as well as by physical contact with the C. parapsilosis cell surface. We propose that non-invasive commensals can be used to inhibit virulence features of pathogens and deserve further study as a non-pharmacological strategy to protect the fragile epithelial barriers of premature infants.

    Mother's own milk is widely recognized as the optimal feeding for term infants, but also provides health benefits that are of vital importance for sick and preterm infants in neonatal intensive care units (NICUs), even though the growth and neurodevelopmental needs of very premature infants are best met by appropriate fortification of human milk (HM). When mother's milk is unavailable or in short supply, donor milk (DM) represents the second best alternative and, although some nutritional elements are inactivated by the pasteurization process, it still has documented advantages compared to formula. Occasionally, the concern that the use of DM might decrease breastfeeding is being raised, but reports exist in literature showing that the use of donor HM in the NICU increases breastfeeding rates at discharge for VLBW infants. The demonstrated benefits of HM highlight the importance of educating health care professionals in breastfeeding support.

  10. Enteral nutrition for optimal growth in preterm infants

    PubMed Central

    2016-01-01

    Early, aggressive nutrition is an important contributing factor of long-term neurodevelopmental outcomes. To ensure optimal growth in premature infants, adequate protein intake and optimal protein/energy ratio should be emphasized rather than the overall energy intake. Minimal enteral nutrition should be initiated as soon as possible in the first days of life, and feeding advancement should be individualized according to the clinical course of the infant. During hospitalization, enteral nutrition with preterm formula and fortified human milk represent the best feeding practices for facilitating growth. After discharge, the enteral nutrition strategy should be individualized according to the infant's weight at discharge. Infants with suboptimal weight for their postconceptional age at discharge should receive supplementation with human milk fortifiers or nutrient-enriched feeding, and the enteral nutrition strategy should be reviewed and modified continuously to achieve the target growth parameters.

    In humans, painful stimuli can arrive to the brain at 20-22 weeks of gestation. Therefore several researchers have devoted their efforts to study fetal analgesia during prenatal surgery, and during painful procedures in premature babies. Aim of this paper is to gather from scientific literature the available data on the signals that the human fetus and newborns produce, and that can be interpreted as signals of pain. Several signs can be interpreted as signals of pain. We will describe them in the text. In infants, these signs can be combined to create specific and sensible pain assessment tools, called pain scales, used to rate the level of pain.

    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. Thus, hypotonic preterm infants and infants

    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.

    Recent studies suggest that premature neonates exposed to music have reduced symptoms of stress, faster weight gain, and shorter neonatal intensive care unit (NICU) stays. This pilot study attempted to measure contingent effects of mothers' singing during feedings. Mothers sang to their babies during 2 of 4 feedings on 2 consecutive days, logging songs they sang, and subjectively evaluating each feeding. Infants' heart and respiration rates were recorded as well as duration of feeding and volume of fluid taken orally; feeding velocity and percent of feeding goal were calculated. In paired t tests, no significant benefits or deterrents assignable to the singing were observed.

    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.

    Temperamental regulatory competence and social communication in term and preterm infants at 12 months corrected age was studied in a randomized controlled intervention trial aimed at enhancing maternal sensitive responsiveness. Surviving infants <2000 g from a geographically defined area were randomized to an intervention (71) or a control group (69), and compared with term infants (74). The intervention was a modified version of the "Mother-Infant Transaction Program". Regulatory competence was measured with the Infant Behavior Questionnaire, and social communication with the Early Social Communication Scales. Preterm intervention infants with low regulatory competence had higher responding to joint attention than preterm control infants. A sensitizing intervention may moderate the association between temperament and social communication, and thus allow an alternative functional outlet for preterm infants low in regulatory competence. The finding may have implications for conceptualizations of the role of early sensitizing interventions in promoting important developmental outcomes for premature infants.
