    Prematurity affects a significant portion (10-12%) of children in the Unites States, with potential for physical, psychological, neurodevelopmental, and behavioral impairments continuing long past the neonatal period. The specific aim of this research was to evaluate pediatric primary and specialty care providers' knowledge and understanding of neurodevelopmental outcomes of children born prematurely. Pediatric nurse practitioner (PNP) members of the National Association of Pediatric Nurse Practitioners participated in an online survey using the 33-item Premature Birth Knowledge Scale (PB-KS) to assess their knowledge of current neurodevelopmental outcomes of children born prematurely. Neither years of practice as a registered nurse nor as a PNP predicted performance on the PB-KS. The mean score on the PB-KS in the PNP sample was 17.8 (possible score = 0-33), with a mean accuracy of 53.9%. Higher scores on the PB-KS were correlated with higher perceived level of preparation to care for children born prematurely. To our knowledge, this is the first study to use the PB-KS with pediatric primary and specialty providers. PNPs are uniquely situated to educate and support families facing the long-term consequences of premature birth; to do so they must maintain accurate understanding of current outcomes.

    To investigate the early diagnosis with MRI changes, MRI types and short-term neurodevelopmental outcome of preterm infants with punctate white matter damage (PWMD). There were 44 preterm infants with PWMD (group A) from March 2009 to August 2010 at the neonatal ward of Shengjing Hospital of China Medical University, according to the number, shape and distribution of the lesions, group A was divided into dot injury group (A1), clusters group (A2) and linear group (A3), the first MRI and DWI scan of all cases were within 14 days after birth, and 17 subjects received re-examination with the MRI in the hospital. Twenty preterm infants with normal MRI (group B) received the follow-up, according to the age, 20 normal full-term infants were selected (group C) as the control group using paired design. Mental development index (MDI) and psychomotor development index (PDI) were determined using Bayley scales of infant development-II. First MRI scan:in 44 infants with PWMD, group A1, A2, A3 separately had, 10, and 9 infants. MRI follow up in 17 cases showed that in 4 cases of A1 group the dot lesions disappeared; in 3 of 4 cases in clusters group who received re-examination, the lesions disappeared, 1 case had periventricular leukomalacia (PVL); in 5 of the 9 cases who had re-examination in linear group the lesions disappeared, while in 4 cases the lesions evolved into PVL. MDI and PDI: Group A [MDI (102.9 ± 15.5) , PDI (107.7 ± 17.5) ] was lower than that of group B[MDI (114.0 ± 13.1) , PDI (120.8 ± 9.4) ], group C [MDI (114.2 ± 12.2) , PDI (119.5 ± 10.7) ] (P A2 [MDI (100.8 ± 12.5) , PDI (105.0 ± 12.1) ] showed significantly reduced values compared with group B, Group C, Group A1 (P A2 (P dot-like and clustered injury that are easy to be absorbed and disappear, but the linear lesions are likely to evolve into PVL. In addition, the cluster-like and linear injury have an influence on short-term cognition and motion development, especially the outcome of linear injury

    Diffuse excessive high signal intensity (DEHSI) may represent damage to the white matter in preterm infants, but may be best studied alongside quantitative markers. Limited published data exists on its neuro-developmental implications. The purpose of this study was to assess whether preterm children with DEHSI at term-corrected age have abnormal neuro-developmental outcome. This was a prospective observational study of 67 preterm infants with MRI of the brain around term-equivalent age, including diffusion-weighted imaging (DWI). Images were reported as being normal, overtly abnormal or to show DEHSI. A single observer placed six regions of interest in the periventricular white matter and calculated the apparent diffusion coefficients (ADC). DEHSI was defined as (1) high signal on T2-weighted images alone, (2) high signal with raised ADC values or (3) raised ADC values independent of visual appearances. The neuro-development was assessed around 18 months' corrected age using the Bayley Scales of Infant and Toddler Development (3rd Edition). Standard t tests compared outcome scores between imaging groups. No statistically significant difference in neuro-developmental outcome scores was seen between participants with normal MRI and DEHSI, regardless of which definition was used. Preterm children with DEHSI have similar neuro-developmental outcome to those with normal brain MRI, even if the definition includes objective markers alongside visual appearances. (orig.)

    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) (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 91–95% (compared to 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 neurocognitive care visits may improve neurocognitive outcomes in this high-risk group. Long-term follow up to detect and address developmental, learning, behavioral, and social problems is critical for children born at these early gestational ages. The striking similarities in response to extreme prematurity in the lung and brain imply that agents and techniques that benefit one organ are likely to also benefit the other. Finally, since therapy and supportive care continue to change, the outcomes of ELBW infants are ever evolving. Efforts to minimize injury, preserve

    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. Copyright © 2011 Elsevier Inc. All rights reserved.

    To study the effects of neurodevelopmental treatment (NDT) on motor and cognitive development of critically ill premature infants. There were 203 infants, who were less than 32 week gestational age (GA), with very-low-birth weight, were included in the study. The infants were assigned to NDT group (n = 96) or control group (n = 107) according to the parent's decision. The infants in NDT group received NDT intervention once per week from corrected age (CA) 1 month to 3 months, and 3 to 5 times per week in the following 9 months. NDT intervention included elongation, establishing alignment, optimizing base of support, facilitation and inhibition, stimulation for activating muscle activity. Both groups received family intervention, such as massage and exercise based on early education. Bayley Scales of Infant Development-II (BSID-II) score was assessed at 3,6,9,12 months CA for all the infants. NDT intervention achieved significant effects on motor and cognitive development. Mental development index (MDI) and psychomotor development index (PDI) of BSID-II were significant higher in NDT group (P children in NDT group (16.67%) and 12 (12.12%) in control group at 12 months CA, there was no significant difference between the two groups (P > 0.05). NDT intervention can improve motor and cognitive development in critically ill premature infants within 12 months CA.

    Full Text Available Introduction: Modulating the stress response and perioperative factors can have a paramount impact on the neurodevelopmental outcome of infants who undergo cardiac surgery utilizing cardiopulmonary bypass. Materials and Methods: In this single center prospective follow-up study, we evaluated the impact of three different anesthetic techniques on the neurodevelopmental outcomes of 19 children who previously underwent congenital cardiac surgery within their 1 st year of life. Cases were done from May 2011 to December 2013. Children were assessed using the Stanford-Binet Intelligence Scales (5 th edition. Multiple regression analysis was used to test different parental and perioperative factors that could significantly predict the different neurodevelopmental outcomes in the entire cohort of patients. Results: When comparing the three groups regarding the major cognitive scores, a high-dose fentanyl (HDF patients scored significantly higher than the low-dose fentanyl (LDF + dexmedetomidine (DEX (LDF + DEX group in the quantitative reasoning scores (106 ± 22 vs. 82 ± 15 P = 0.046. The bispectral index (BIS value at the end of surgery for the -LDF group was significantly higher than that in LDF + DEX group (P = 0.011. For the entire cohort, a strong correlation was seen between the standard verbal intelligence quotient (IQ score and the baseline adrenocorticotropic hormone level, the interleukin-6 level at the end of surgery and the BIS value at the end of the procedure with an R 2 value of 0.67 and P < 0.04. There was an inverse correlation between the cardiac Intensive Care Unit length of stay and the full-scale IQ score (R = 0.4675 and P 0.027. Conclusions: Patients in the HDF group demonstrated overall higher neurodevelopmental scores, although it did not reach statistical significance except in fluid reasoning scores. Our results may point to a possible correlation between blunting the stress response and improvement of the neurodevelopmental

  17. Relationship between Proton Magnetic Resonance Spectroscopy of Frontoinsular Gray Matter and Neurodevelopmental Outcomes in Very Low Birth Weight Children at the Age of 4.

    Full Text Available Very low birth weight is associated with long term neurodevelopmental complications. Macroscopic brain abnormalities in prematurity survivors have been investigated in several studies. However, there is limited data regarding local cerebral metabolic status and neurodevelopmental outcomes. The purpose of this study was to characterize the relationship between proton magnetic resonance spectra in basal ganglia, frontal white matter and frontoinsular gray matter, neurodevelopmental outcomes assessed with the Leiter scale and the Developmental Test of Visual Perception and selected socioeconomic variables in a cohort of very low birth weight children at the age of four. Children were divided in three groups based on the severity of neurodevelopmental impairment. There were no differences in spectroscopy in basal ganglia and frontal white matter between the groups. Lower concentrations of N-acetylaspartate (NAA, choline (Cho and myoinositol (mI were observed in the frontoinsular cortex of the left hemisphere in children with neurodevelopmental impairment compared to children with normal neurodevelopmental outcomes. Higher parental education, daycare attendance and breastfeeding after birth were associated with more favorable neurodevelopmental prognosis, whereas rural residence was more prevalent in children with moderate and severe impairment. Our study demonstrates the role of long term neurometabolic disruption in the left frontoinsular cortex and selected socioeconomic variables in determination of neurodevelopmental prognosis in prematurity survivors.

    To systematically review the existing literature on neurodevelopmental outcomes in children born after medically assisted reproduction compared with those of children born after spontaneous conception. Systematic review. Not applicable. Children born after medically assisted reproduction vs. reference groups of spontaneously conceived children. Data were reviewed from worldwide published articles, without restrictions as to publication year or language. A total of 80 studies included between 31 and 2,446,044 children. Child neurodevelopmental outcomes categorized as cognitive, behavioral, emotional or psychomotor development, or diagnoses of mental disorders. For infants, studies on psychomotor development showed no deficits, but few investigated cognitive or behavioral development. Studies on toddlers generally reported normal cognitive, behavioral, socio-emotional, and psychomotor development. For children in middle childhood, development seems comparable in children born after assisted reproduction and controls, although fewer studies have been conducted with follow-up to this age. Very few studies have assessed neurodevelopmental outcomes among teens, and the results are inconclusive. Studies investigating the risk of diagnoses of mental disorders are generally large, with long follow-up, but the results are inconsistent. It may tentatively be concluded that the neurodevelopment of children born after fertility treatment is overall comparable to that in children born after spontaneous conception.

    We present the neurodevelopmental outcome of patients with isolated borderline fetal ventriculomegaly. The present study was carried out at the Department of Pediatric Neurology, Istanbul Medical Faculty, Istanbul University in July-December 2010. Prenatal second trimester detailed ultrasound examinations were performed by obstetricians at the Prenatal Diagnosis Department of Istanbul Medical School, and 31 consecutive patients aged 8-33 months have been included in the study. Four patients with atrial diameters of over 15 mm and three patients with central nervous system development anomalies were excluded from the study. In order to assess the neuromotor development of patients, neurologic examinations and the Bayley Scales of Infant Development (BSID-III) were used. Nine patients were female (29%) and 22 were male (71%). In the postnatal period, tuberous sclerosis was found in one patient, Down syndrome in one, and equinovarus foot deformity in one. Atrial diameter was patients and >12 mm in 13. Cranial ultrasounds done in the first postnatal month revealed persisting ventriculomegaly in nine patients. The two patients who scored significantly low in all areas on the Bayley Scales of Infant Development were the patients with Down syndrome and tuberous sclerosis. The one scoring low in the motor area was the patient with the equinovarus foot deformity. The BSID-III scores of the patients whose prenatal ventricle diameter was patients showing slight developmental delay were the ones whose cranial ultrasound in the first postnatal month showed persisting ventriculomegaly. In patients with borderline fetal ventriculomegaly, atrial diameter being more than 12 mm, the condition persisting in the first postnatal month and the presence of accompanying syndromes and malformations all constitute clear risk factors for neurodevelopmental outcome.

    Rural and remote residents in Australia have long experienced unfavourable health outcomes compared to their urban counterparts. To study neurodevelopmental outcome at 2-3 years of age, corrected for prematurity of extremely preterm infants admitted to a regional neonatal Australian network from rural and urban regions (based on usual location of maternal residence). A multicenter population-based cohort study in which surviving urban and rural infants functional disability was defined as developmental delay (GQ or MDI>2 SD below the mean), cerebral palsy (aided for walking), sensorineural or conductive deafness (requiring amplification), and bilateral blindness (visual acuity urban infants were evaluated. Infants lost to follow-up were of slightly higher gestational age and birth weight. Both rural and urban assessed groups were comparable in gestation and birth weight percentile. In comparison to their urban counterparts, the rural group had more outborn infants (19.8% vs. 4.6%, pfunctional disability (OR 0.77, 95% CI 0.52-1.23, p=0.176). This finding was not significantly altered by limiting the analysis to different gestational ages. Extremely premature surviving young children from rural areas of residence do not seem to have an increased risk for moderate/severe functional disability. Copyright © 2015 Elsevier Ireland Ltd.

  1. Long-term neurodevelopmental outcome of monochorionic and matched dichorionic twins.

    Directory of Open Access Journals (Sweden)

    Karien E A Hack

    Full Text Available BACKGROUND: Monochorionic (MC twins are at increased risk for perinatal mortality and serious morbidity due to the presence of placental vascular anastomoses. Cerebral injury can be secondary to haemodynamic and hematological disorders during pregnancy (especially twin-to-twin transfusion syndrome (TTTS or intrauterine co-twin death or from postnatal injury associated with prematurity and low birth weight, common complications in twin pregnancies. We investigated neurodevelopmental outcome in MC and dichorionic (DC twins at the age of two years. METHODS: This was a prospective cohort study. Cerebral palsy (CP was studied in 182 MC infants and 189 DC infants matched for weight and age at delivery, gender, ethnicity of the mother and study center. After losses to follow-up, 282 of the 366 infants without CP were available to be tested with the Griffiths Mental Developmental Scales at 22 months corrected age, all born between January 2005 and January 2006 in nine perinatal centers in The Netherlands. Due to phenotypic (unalikeness in mono-or dizygosity, the principal investigator was not blinded to chorionic status; perinatal outcome, with exception of co-twin death, was not known to the examiner. FINDINGS: Four out of 182 MC infants had CP (2.2% - two of the four CP-cases were due to complications specific to MC twin pregnancies (TTTS and co-twin death and the other two cases of CP were the result of cystic PVL after preterm birth - compared to one sibling of a DC twin (0.5%; OR 4.2, 95% CI 0.5-38.2 of unknown origin. Follow-up rate of neurodevelopmental outcome by Griffith's test was 76%. The majority of 2-year-old twins had normal developmental status. There were no significant differences between MC and DC twins. One MC infant (0.7% had a developmental delay compared to 6 DC infants (4.2%; OR 0.2, 95% 0.0-1.4. Birth weight discordancy did not influence long-term outcome, though the smaller twin had slightly lower developmental scores than its

    To examine the prevalence of neurodevelopmental disability and the predictive value of pre-, peri-, and postnatal data on neurologic, sensory, cognitive, and motor function in children born extremely preterm. This was a prospective observational study of all infants born in Norway between 1999 and 2000 with gestational ages between 22 and 27 weeks or birth weights between 500 and 999 g. Cognitive function was assessed with the Wechsler Preschool and Primary Scale of Intelligence-Revised, motor function with the Movement Assessment Battery for Children, and severity of cerebral palsy with the Gross Motor Function Classification for Cerebral Palsy. Disabilities were described as mild, moderate, or severe. Of 371 eligible children, 306 (82%) were examined at a mean (SD) age of 5 years and 10 (4) months. For gestational age less than 28 weeks (n = 239), 26 (11%) children had cerebral palsy alone (n = 21) or in combination with blindness (n = 3) or deafness (n = 2); 1 was blind and 1 was deaf. Of the remaining children, the mean full-scale IQ was 94 ± 15, and significant predictors were (values given as the difference in IQ points [95% confidence intervals]) high maternal education (9.6 [5.7-13.4]), preeclampsia (-7.7 [-12.7 to -2.7]), and retinopathy of prematurity higher than grade 2 (-17.5 [-27.1 to -8.0]). Movement Assessment Battery for Children scores were positively associated with gestational age and prenatal steroids and negatively associated with being small for gestational age, male gender, and having retinopathy of prematurity. Moderate to severe neurodevelopmental disability was more common for gestational ages 25 weeks or less (28 of 87 children) than for 26 to 27 weeks (12 of 152 children; P children; P = .001). The outcome was poorer for children with gestational ages of 25 weeks or less compared with those with gestational ages between 26 and 27 weeks. For those without cerebral palsy, blindness, or deafness, however, gestational age had a limited

    Full Text Available We examined the effects of prematurity (37 weeks of gestation and low birthweight (2500 g on mental health outcomes among US children aged 2–17 years. The 2011-2012 National Survey of Children’s Health ( = 95,677 was used to estimate prevalence of parent-reported mental health problems in children. Prevalence of mental disorders was 22.9% among children born prematurely, 28.7% among very-low-birth-weight (1500 g children, and 18.9% among moderately low-birth-weight (1500–2499 g children, compared with 15.5% in the general child population. Compared to those born full term, children born prematurely had 61% higher adjusted odds of serious emotional/behavioral problems, 33% higher odds of depression, and 58% higher odds of anxiety. Children born prematurely had 2.3 times higher odds of autism/ASD, 2.9 times higher odds of development delay, and 2.7 times higher odds of intellectual disability than term children. Very-low-birth-weight children had 3.2 times higher odds of autism/ASD, 1.7 times higher odds of ADD/ADHD, 5.4 times higher odds of development delay, and 4.4 times higher odds of intellectual disability than normal-birth-weight children. Social factors were significant predictors of mental disorders in both premature/low-birth-weight and term/normal-birth-weight children. Neurodevelopmental conditions accounted for the relationship between prematurity and depression/anxiety/conduct problems. Prematurity and low birthweight are significant risk factors for mental health problems among children.

    Full Text Available Abstract Background Amnioreduction remains a treatment option for pregnancies with twin-to-twin transfusion syndrome (TTTS not meeting criteria for laser surgery or those in which it is not feasible. Amnioreduction is a relatively simple treatment which does not require sophisticated technical equipment. Previous reports of conservative management have indicated that major neurodevelopmental impairment occurs in 14.3-26% of survivors. The purpose of this study was to investigate long-term neurodevelopmental outcome in conservatively treated TTTS. Methods During the nine-year study period from January 1996 to December 2004, all pregnancies with TTTS who were admitted to our center were investigated. TTTS was diagnosed by using standard prenatal ultrasound criteria, and staged according to the criteria of Quintero et al. We reviewed gestational age at diagnosis, gestational age at delivery, the stage of TTTS at diagnosis, and diagnosis to delivery interval. Neonatal cranial ultrasound findings were reviewed and the neurodevelopmental outcomes were evaluated. Results Twenty-one pregnancies with TTTS were included. Thirteen pregnancies (62% were treated with serial amnioreduction. The mean gestational age at delivery was 28 weeks (22 - 34 weeks. The perinatal mortality rate was 42.9%. Twenty survivors were followed up until at least 3 years of age. The mean age at follow-up was 6.3 years (3 - 12 years. Six children (30% had neurodevelopmental impairment. Four children (20% had major neurodevelopmental impairment and two children (10% had minor neurodevelopmental impairment. Children with neurodevelopmental impairment were delivered before 29 weeks of gestation. Conclusions Our study showed a high rate of perinatal mortality and a high rate of major neurodevelopmental impairment in conservatively treated TTTS. The long-term outcomes for the survivors with TTTS were good when survivors were delivered after 29 weeks of gestation.

    To determine whether preterm premature rupture of membranes (PPROM) before 24 weeks is an independent risk factor for poor outcome in preterm neonates. A retrospective comparative cohort study was conducted, including viable premature infants born between 25 and 34-weeks gestation. Each preterm case with early PPROM was matched with two preterm controls of the same gestational age at birth, sex and birth date and who were born spontaneously with intact membranes. Logistic regression was performed to identify independent risk factors associated with composite respiratory and perinatal adverse outcomes for the overall population of preterm infants. Thirty-five PPROM cases were matched with 70 controls. Extreme prematurity (26-28 weeks) was an independent risk factor for composite perinatal adverse outcomes [odds ratio (OR) 43.9; p = 0.001]. Extreme prematurity (OR 42.9; p = 0.001), PPROM (OR 7.1; p = 0.01), male infant (OR 5.2; p = 0.02) and intrauterine growth restriction (IUGR, OR 4.8; p = 0.04) were factors for composite respiratory adverse outcomes. Preterm premature rupture of membranes before viability represents an independent risk factor for composite respiratory adverse outcomes in preterm neonates. Extreme prematurity may represent the main risk factor for both composite respiratory and perinatal adverse outcomes. ©2013 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    Very preterm children are at a high risk for neurodevelopmental impairments, but there is variability in the pattern and severity of outcome. Neonatal magnetic resonance imaging (MRI) enhances the capacity to detect brain injury and altered brain development and assists in the prediction of high-risk children who warrant surveillance and early intervention. This review describes the application of conventional and advanced MRI with very preterm neonates, specifically focusing on the relationship between neonatal MRI findings and later neurodevelopmental outcome. Research demonstrates that conventional MRI is strongly associated with neurodevelopmental outcome in childhood. Further studies are needed to examine the role of advanced MRI techniques in predicting outcome in very preterm children, but early research findings are promising. In conclusion, neonatal MRI is predictive of later neurodevelopment but is dependent on appropriately trained specialists and should be interpreted in conjunction with other clinical and social information.

    Postnatal dexamethasone is associated with reduction in bronchopulmonary dysplasia. There remains, however, concern that its short-term benefits are accompanied by long-term adverse effects e.g. poorer neurodevelopmental outcomes. Our aim was to determine the effects of administration of postnatal dexamethasone on respiratory and neurodevelopmental outcome at two years of age after adjusting for neonatal and infant risk factors. The study included 412 infants born at 23-28 weeks of gestation, 29% had received postnatal dexamethasone. Two outcomes were examined, respiratory hospital admissions in the past 12 months and neurodevelopmental impairment. Logistic regression, adjusted for sex, birthweight z-score, gestation, maternal smoking, oxygen dependency at 36 weeks, airleak, patent ductus arteriosus, pulmonary haemorrhage, major ultrasound abnormality, mode of ventilation and age at assessment, was undertaken. After adjustment, postnatal dexamethasone was associated with significantly increased proportions of both respiratory hospital readmission: (0.35 vs 0.15, difference = 0.20; 95% CI: 0.08, 0.31) and neurodevelopmental impairment (0.59 vs 0.45, difference = 0.14; 95% CI: 0.02, 0.26). Postnatal dexamethasone use in extremely preterm infants is associated with increased risks of respiratory hospital admissions and neurodevelopmental impairment. These associations were not explained by excess neonatal morbidities.

    Angelman syndrome (AS) is a neurogenetic disorder characterized by intellectual disability, developmental delay, lack of speech, and epileptic seizures. Previous studies have indicated that children with AS due to 15q11.2-q13 deletions have a more severe developmental delay and present more often autistic features than those with AS caused by other genetic etiologies. The present study investigated the neurodevelopmental profiles of the different genetic etiologies of AS, and examined the evolution of mental development and autistic features over a 12-year period in children with a 15q11.2-q13 deletion. This study included 42 children with AS. Twelve had a Class I deletion, 18 had Class II deletions, three showed atypical large deletions, five had paternal uniparental disomy (pUPD) and four had UBE3A mutations. Children with a deletion (Class I and Class II) showed significantly reduced developmental age in terms of visual perception, receptive language, and expressive language when compared to those with a UBE3A mutation and pUPD. Within all subgroups, expressive language performance was significantly reduced when compared to the receptive performance. A follow-up study of seven AS cases with 15q11.2-q13 deletions revealed that over 12 years, the level of autistic features did not change, but both receptive and expressive language skills improved.

    Prolonged electroencephalographic (EEG) discontinuity has been associated with poor neurodevelopmental outcomes after perinatal asphyxia but its predictive value in the era of therapeutic hypothermia (TH) is unknown. In infants undergoing TH for hypoxic-ischaemic encephalopathy (HIE) prolonged EEG discontinuity is associated with cerebral tissue injury on MRI and adverse neurodevelopmental outcome. Retrospective study of term neonates from three UK centres who received TH for perinatal asphyxia, had continuous two channel amplitude-integrated EEG with EEG for a minimum of 48 h, brain MRI within 6 weeks of birth and neurodevelopmental outcome data at a median age of 24 months. Mean discontinuity was calculated using a novel automated algorithm designed for analysis of the raw EEG signal. Of 49 eligible infants, 17 (35%) had MR images predictive of death or severe neurodisability (unfavourable outcome) and 29 (59%) infants had electrographic seizures. In multivariable logistic regression, mean discontinuity at 24 h and 48 h (both p=0.01), and high seizure burden (p=0.05) were associated with severe cerebral tissue injury on MRI. A mean discontinuity >30 s/min-long epoch, had a specificity and positive predictive value of 100%, sensitivity of 71% and a negative predictive value of 88% for unfavourable neurodevelopmental outcome at a 10 µV threshold. In addition to seizure burden, excessive EEG discontinuity is associated with increased cerebral tissue injury on MRI and is predictive of abnormal neurodevelopmental outcome in infants treated with TH. The high positive predictive value of EEG discontinuity at 24 h may be valuable in selecting newborns with HIE for adjunctive treatments. Published by the BMJ Publishing Group Limited.

    Assessment of whether pesticide exposure is associated with neurodevelopmental outcomes in children can best be addressed with a systematic review of both the human and animal peer-reviewed literature. This review analyzed epidemiologic studies testing the hypothesis that exposure to pesticides during pregnancy and/or early childhood is associated with neurodevelopmental outcomes in children. Studies that directly queried pesticide exposure (e.g., via questionnaire or interview) or measured pesticide or metabolite levels in biological specimens from study participants (e.g., blood, urine, etc.) or their immediate environment (e.g., personal air monitoring, home dust samples, etc.) were eligible for inclusion. Consistency, strength of association, and dose response were key elements of the framework utilized for evaluating epidemiologic studies. As a whole, the epidemiologic studies did not strongly implicate any particular pesticide as being causally related to adverse neurodevelopmental outcomes in infants and children. A few associations were unique for a health outcome and specific pesticide, and alternative hypotheses could not be ruled out. Our survey of the in vivo peer-reviewed published mammalian literature focused on effects of the specific active ingredient of pesticides on functional neurodevelopmental endpoints (i.e., behavior, neuropharmacology and neuropathology). In most cases, effects were noted at dose levels within the same order of magnitude or higher compared to the point of departure used for chronic risk assessments in the United States. Thus, although the published animal studies may have characterized potential neurodevelopmental outcomes using endpoints not required by guideline studies, the effects were generally observed at or above effect levels measured in repeated-dose toxicology studies submitted to the U.S. Environmental Protection Agency (EPA).

    The objective of the study was to assess predictive value of serial diffusion tensor MRI (DTI) for the white matter injury and neurodevelopmental outcome in a cohort of premature infants. Twenty-four infants less than 32 weeks' gestation were stratified to a control group (n = 11), mild brain injury with grades 1-2 of intraventricular hemorrhage (n = 6) and severe brain injury with grades 3-4 intraventricular hemorrhage (n = 4). Serial DTI studies were performed at around 30 and 36 weeks' gestation. Fractional anisotropy (FA) and apparent diffusion coefficient were calculated. Twelve infants were followed up for developmental outcome. Developmental testing was performed with the Bayley Scales of Infant Development to obtain psychomotor index (Performance Developmental Index). Apparent diffusion coefficient was higher in the severe injury group at the second MRI in the central and occipital white matter, and corona radiata; FA was lower in optic radiation compared to controls. Performance Developmental Index score correlated with FA on the scan taken at the 30th week and inversely with the change of FA between scans in internal capsule and occipital white matter. A low value of FA at 30 weeks and a higher change of FA predicted less favorable motor outcome at 2 years and suggests that early subtle white matter injury can be detected in premature infants even without obvious signs of injury. 2007 S.

    A significant proportion of children born preterm will experience some level of neurodevelopmental impairment. Changes in placental function have been observed with many antenatal conditions that are risk factors for preterm birth and/or poor neurodevelopment including fetal growth restriction and in-utero inflammation. This review will highlight placental factors that have been studied to understand the underlying mechanisms and identify biomarkers that lead to poor child neurodevelopmental outcomes. These include changes in gross morphological and histopathological structure and the placental inflammatory response to prenatal infection. Further, we will describe the placenta's role as both a barrier to maternally-derived bioactive substances critical for normal fetal brain development, such as cortisol, and a source of neuroactive steroids and neurotrophins known to have critical functions in neuronal proliferation, axonal growth, myelination and the regulation of apoptosis. Finally, emerging data supporting the potential utility of novel placental biomarkers in the early prediction of poor neurodevelopmental outcome in infants born both preterm and term will be discussed. These include the assessment of genetic variants (e.g. single nucleotide polymorphisms in placental tissue) and epigenetic biomarkers (e.g. placental microRNAs and placental DNA methylation). With the placenta the key tissue regulating the fetal environment, integration of observed changes in placental function with genetic and epigenetic variations may advance our ability to predict future infant health. Ultimately, this may facilitate targeted allocation of health resources with the aim of improving lifelong neurodevelopmental capability. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Brain injury during prenatal and preoperative postnatal life might play a major role in neurodevelopmental impairment in infants with congenital heart disease (CHD) who require corrective or palliative surgery during infancy. A systematic review of cerebral findings during this period in relation to neurodevelopmental outcome (NDO), however, is lacking. To assess the association between prenatal and postnatal preoperative cerebral findings and NDO in infants with CHD who require corrective or palliative surgery during infancy. PubMed, Embase, reference lists. We conducted 3 different searches for English literature between 2000 and 2016; 1 for prenatal cerebral findings, 1 for postnatal preoperative cerebral findings, and 1 for the association between brain injury and NDO. Two reviewers independently screened sources and extracted data on cerebral findings and neurodevelopmental outcome. Quality of studies was assessed using the Newcastle-Ottawa Quality Assessment Scale. Abnormal cerebral findings are common during the prenatal and postnatal preoperative periods. Prenatally, a delay of cerebral development was most common; postnatally, white matter injury, periventricular leukomalacia, and stroke were frequently observed. Abnormal Doppler measurements, brain immaturity, cerebral oxygenation, and abnormal EEG or amplitude-integrated EEG were all associated with NDO. Observational studies, different types of CHD with different pathophysiological effects, and different reference values. Prenatal and postnatal preoperative abnormal cerebral findings might play an important role in neurodevelopmental impairment in infants with CHD. Increased awareness of the vulnerability of the young developing brain of an infant with CHD among caregivers is essential. Copyright © 2017 by the American Academy of Pediatrics.

  1. Cord Blood DNA Methylation Biomarkers for Predicting Neurodevelopmental Outcomes

    Full Text Available Adverse environmental exposures in pregnancy can significantly alter the development of the fetus resulting in impaired child neurodevelopment. Such exposures can lead to epigenetic alterations like DNA methylation, which may be a marker of poor cognitive, motor and behavioral outcomes in the infant. Here we review studies that have assessed DNA methylation in cord blood following maternal exposures that may impact neurodevelopment of the child. We also highlight some key studies to illustrate the potential for DNA methylation to successfully identify infants at risk for poor outcomes. While the current evidence is limited, in that observations to date are largely correlational, in time and with larger cohorts analyzed and longer term follow-up completed, we may be able to develop epigenetic biomarkers that not only indicate adverse early life exposures but can also be used to identify individuals likely to be at an increased risk of impaired neurodevelopment even in the absence of detailed information regarding prenatal environment.

    Elevated rates of epilepsy and motor impairments including cerebral palsy are observed in children who were born prematurely. Maternal antenatal magnesium supplementation has been associated with decreased rates of cerebral palsy in infants born prematurely. Our objective was to determine whether the neonatal serum magnesium level between 24 and 48 hours after birth is associated with better long-term neurodevelopmental outcomes (epilepsy, motor impairment) in premature infants. We performed a retrospective cohort analysis in infants born less than 37-weeks gestation over a ten-year period. Prenatal, perinatal, and postnatal clinical and demographic information was collected. Crude and adjusted odds ratios were estimated under generalized linear models with generalized estimating equations to examine the association of the neonatal serum magnesium level between 24 and 48 hours after birth with the risk of epilepsy and/or motor impairment (spasticity; hypotonia; cerebral palsy). The final cohort included 5461 infants born less than 37-weeks gestation from 2002 to 2011. The adjusted relative risk ratio for the combined outcomes of epilepsy and/or motor impairment, controlling for gestational age, current age, maternal magnesium supplementation, maternal steroid administration, five-minute Apgar score, neonatal infection, need for vasopressor use, and birth weight and with serum magnesium level as the main independent variable, was 0.85 (P = 0.24). Stratified analyses by gestational age less than 32 or greater than 32 weeks were not significantly associated with adverse neurodevelopmental outcome (risk ratio = 0.79 and 1.2, P = 0.12 and 0.49, respectively). A multivariate analysis for the risk of motor impairment alone had a risk ratio of 0.94 (P = 0.72). This study demostrates that the neonatal magnesium level between 24 and 48 hours of life in premature infants is not significantly associated with the risk for developing epilepsy or motor impairment

    Bronchopulmonary dysplasia (BPD) is a pulmonary disease associated with poor neurodevelopmental and medical outcomes. Patients with BPD are medically fragile, at high risk for complications and require interdisciplinary care. We tested the hypothesis that a chronic care approach for BPD would improve neurodevelopmental outcomes relative to the National Institute of Child and Human Development Neonatal Research Network (NICHD NRN) and reduce medical complications. Infants were followed as inpatients and outpatients. Bayley developmental exams were carried out at 18-24 months of age and compared with the NICHD NRN report. Finally, rates of readmission (a proxy for medical complications) were compared before and after implementation of the Comprehensive Center for BPD (CCBPD). Developmental scores obtained in 2007 and 2008 show that 12 and 10% of patients with moderate BPD (n=61) had Bayley Scores <70 for mental and motor indices respectively, whereas corresponding national rates were 35 and 26%. For patients with severe BPD (n=46), 15 and 11% of patients within the CCBPD vs 50 and 42% of national patients scored <70 for mental and motor indices, respectively. Finally, readmission rates dropped from 29% in the year before the implementation of the CCPD (n=269) to 5% thereafter (n=866, P<0.0001). The encouraging neurodevelopmental outcomes and readmission rates associated with a chronic care approach to BPD suggest these infants may be best served by a comprehensive interdisciplinary approach to care that focuses on neurodevelopment throughout the hospital stay.

    The impact that congenital heart disease (CHD) has on the neurodevelopment of children with Down syndrome (DS) is unknown and potentially has implications for targeted early intervention. This study assessed the relationship between CHD that required surgery in the first year of life and neurodevelopmental, behavioral and emotional functioning outcomes in children with DS. A retrospective chart review of 1092 children (0-18 years) with DS who visited a single institution from 8/08-8/13 was performed. Children who underwent at least one of nine neurodevelopmental (cognitive, language, developmental) or academic tests were included in the analysis (N = 178). Cohort was age-divided into infants/toddlers (0-2 years), preschoolers (3-5 years), and school age/adolescent (6-18 years). Test scores of children with DS who underwent cardiac surgery in the first year of life were compared to children with DS without CHD. T test, chi-square and Mann Whitney U tests were used where appropriate. Infants/toddlers with cardiac surgery had lower scores for receptive (P = .01), expressive (P = .021) and composite language (P children with cardiac surgery there were no differences in IQ scores, language scores, or academic achievement scores compared to those without CHD. Also at school-age there was no difference in the incidence of ADHD, executive function or on internalizing and externalizing behavior scores. Children with DS undergoing cardiac surgery during the first year demonstrated poorer neurodevelopmental outcomes as infants/toddler but had no difference at school age compared to children with DS without CHD. These results will guide early interventions to optimize neurodevelopmental outcomes in children with DS and will help with family counseling after CHD repair. © 2016 Wiley Periodicals, Inc.

    To describe outcomes in twin pregnancies with preterm premature rupture of membranes (PPROM). Dichorionic twin pregnancies complicated by PPROM at premature rupture of membranes (PROM), latency from PROM to delivery, and infection were examined. In 49 twin pregnancies, the median gestational age at PROM was 31 weeks with a median latency between PROM and delivery of 0 days (interquartile range 0-6). Latency intervals of >or=2 and >or=7 days were achieved by 40.8% and 22.4%, respectively. PPROM at or= 2 days (70.6% vs. 25.0%) and >or=7 days (47.1% vs. 9.4%). There was a significant relationship between latency and clinical and histologic signs of infection. After 30 weeks, most twin pregnancies with PPROM delivered within 2 days. Infection appears to be a consequence rather than a cause of PPROM in most cases.

    Objectives Despite improved survival in children with hypoplastic left heart syndrome (HLHS), significant concern persists regarding their neurodevelopmental (ND) outcomes. Previous studies have identified patient factors, such as prematurity and genetic syndromes, to be associated with worse ND outcomes. However, no consistent relationships have been identified among modifiable management factors, including cardiopulmonary bypass strategies, and ND outcomes after cardiac surgery in infancy. Studies in immature animals, including primates, have demonstrated neurodegeneration and apoptosis in the brain after certain levels and extended durations of anesthetic exposure. Retrospective human studies have also suggested relationships between adverse ND effects and anesthetic exposure. Methods Cumulative minimum alveolar concentration hours (MAC-hrs) of exposure to volatile anesthetic agents (VAA) (desflurane, halothane, isoflurane and sevoflurane) were collected from an anesthetic database and medical record review for 96 patients with HLHS or variants. ND testing was performed between ages 4 and 5 years including full-scale IQ, verbal IQ, performance IQ and processing speed. Four generalized linear modes were hypothesized a priori and tested using a Gaussian (normal) distribution with an identity link. Results Cumulative VAA exposure ranged from 0 to 35.3 MAC-hrs (median 7.5 hrs). Using specified covariates identified previously as significant predictors of ND outcomes, statistically significant relationships were identified between total MAC-hrs exposure and worse full-scale IQ and verbal IQ scores (p’s < 0.05) alone and after adjusting for relevant covariates. Conclusion Increased cumulative MAC-hrs exposure to VAA is associated with worse ND outcomes in certain domains in children with HLHS and variants. PMID:27183886

    More than 50 percent of all infants born very preterm will experience significant motor and cognitive impairment. Provision of early intervention is dependent upon accurate, early identification of infants at risk of adverse outcomes. Magnetic resonance imaging at term equivalent age combined with General Movements assessment at 12 weeks corrected age is currently the most accurate method for early prediction of cerebral palsy at 12 months corrected age. To date no studies have compared the use of earlier magnetic resonance imaging combined with neuromotor and neurobehavioural assessments (at 30 weeks postmenstrual age) to predict later motor and neurodevelopmental outcomes including cerebral palsy (at 12-24 months corrected age). This study aims to investigate i) the relationship between earlier brain imaging and neuromotor/neurobehavioural assessments at 30 and 40 weeks postmenstrual age, and ii) their ability to predict motor and neurodevelopmental outcomes at 3 and 12 months corrected age. This prospective cohort study will recruit 80 preterm infants born ≤ 30 week's gestation and a reference group of 20 healthy term born infants from the Royal Brisbane & Women's Hospital in Brisbane, Australia. Infants will undergo brain magnetic resonance imaging at approximately 30 and 40 weeks postmenstrual age to develop our understanding of very early brain structure at 30 weeks and maturation that occurs between 30 and 40 weeks postmenstrual age. A combination of neurological (Hammersmith Neonatal Neurologic Examination), neuromotor (General Movements, Test of Infant Motor Performance), neurobehavioural (NICU Network Neurobehavioural Scale, Premie-Neuro) and visual assessments will be performed at 30 and 40 weeks postmenstrual age to improve our understanding of the relationship between brain structure and function. These data will be compared to motor assessments at 12 weeks corrected age and motor and neurodevelopmental outcomes at 12 months corrected age

    To determine the incidence and risk factors for neurodevelopmental impairment (NDI) in children with hemolytic disease of the fetus/newborn treated with intrauterine transfusion (IUT). Neurodevelopmental outcome in children at least 2 years of age was assessed using standardized tests, including the Bayley Scales of Infant Development, the Wechsler Preschool and Primary Scale of Intelligence, and the Wechsler Intelligence Scale for Children, according to the children's age. Primary outcome was the incidence of neurodevelopmental impairment defined as at least one of the following: cerebral palsy, severe developmental delay, bilateral deafness, and/or blindness. A total of 291 children were evaluated at a median age of 8.2 years (range, 2-17 years). Cerebral palsy was detected in 6 (2.1%) children, severe developmental delay in 9 (3.1%) children, and bilateral deafness in 3 (1.0%) children. The overall incidence of neurodevelopmental impairment was 4.8% (14/291). In a multivariate regression analysis including only preoperative risk factors, severe hydrops was independently associated with neurodevelopmental impairment (odds ratio, 11.2; 95% confidence interval, 1.7-92.7). Incidence of neurodevelopmental impairment in children treated with intrauterine transfusion for fetal alloimmune anemia is low (4.8%). Prevention of fetal hydrops, the strongest preoperative predictor for impaired neurodevelopment, by timely detection, referral and treatment may improve long-term outcome.

    BACKGROUND: To examine the blood glucose profile and the relationship between blood glucose levels and neurodevelopmental outcome in term infants with hypoxic-ischaemic encephalopathy. METHODS: Blood glucose values within 72 hours of birth were collected from 52 term infants with hypoxic-ischaemic encephalopathy. Hypoglycaemia [< 46.8 mg\\/dL (2.6 mmol\\/L)] and hyperglycaemia [> 150 mg\\/dL (8.3 mmol\\/L)] were correlated to neurodevelopmental outcome at 24 months of age. RESULTS: Four fifths of the 468 blood samples were in the normoglycaemic range (392\\/468:83.8%). Of the remaining 76 samples, 51.3% were in the hypoglycaemic range and (48.7%) were hyperglycaemic. A quarter of the hypoglycaemic samples (28.2%:11\\/39) and a third of the hyperglycaemic samples (32.4%:12\\/37) were recorded within the first 30 minutes of life. Mean (SD) blood glucose values did not differ between infants with normal and abnormal outcomes [4.89(2.28) mmol\\/L and 5.02(2.35) mmol\\/L, p value = 0.15] respectively. In term infants with hypoxic-ischaemic encephalopathy, early hypoglycaemia (between 0-6 hours of life) was associated with adverse outcome at 24 months of age [OR = 5.8, CI = 1.04-32)]. On multivariate analysis to adjust for grade of HIE this association was not statistically significant. Late hypoglycaemia (6-72 hours of life) was not associated with abnormal outcome [OR = 0.22, CI (0.04-1.14)]. The occurrence of hyperglycaemia was not associated with adverse outcome. CONCLUSION: During the first 72 hours of life, blood glucose profile in infants with hypoxic-ischaemic encephalopathy varies widely despite a management protocol. Early hypoglycaemia (0-6 hours of life) was associated with severe HIE, and thereby; adverse outcome.

    Preterm birth is associated with long-term deficits in executive functioning and cognitive performance. As advances in neonatal care enable more preterm infants to survive, development of strategies to address high rates of neurodevelopmental disabilities and poor academic achievement in preterm infants are crucial. Evidence suggests that infants' brains are plastic in nature and, therefore, can be shaped by the environment. Kangaroo care has become popularized as a means of modifying the stress of the NICU environment. However, few studies have examined whether kangaroo care affects neurodevelopmental outcomes in preterm infants. This review examined available literature that investigated the effect of kangaroo care on cognition in preterm infants. Current evidence suggests that short-term benefits of kangaroo care are associated with improved neurodevelopment. However, few studies have examined the long-term impact of kangaroo care on cognitive outcomes in preterm infants. To address neurological disparities in children born preterm, research using kangaroo care as a strategy to improve neurodevelopment in preterm infants is warranted.

    Full Text Available To compare the effects of stress dose hydrocortisone therapy with placebo on survival without neurodevelopmental impairments in high-risk preterm infants.We recruited 64 extremely low birth weight (birth weight ≤1000 g infants between the ages of 10 and 21 postnatal days who were ventilator-dependent and at high-risk for bronchopulmonary dysplasia. Infants were randomized to a tapering 7-day course of stress dose hydrocortisone or saline placebo. The primary outcome at follow-up was a composite of death, cognitive or language delay, cerebral palsy, severe hearing loss, or bilateral blindness at a corrected age of 18-22 months. Secondary outcomes included continued use of respiratory therapies and somatic growth.Fifty-seven infants had adequate data for the primary outcome. Of the 28 infants randomized to hydrocortisone, 19 (68% died or survived with impairment compared with 22 of the 29 infants (76% assigned to placebo (relative risk: 0.83; 95% CI, 0.61 to 1.14. The rates of death for those in the hydrocortisone and placebo groups were 31% and 41%, respectively (P = 0.42. Randomization to hydrocortisone also did not significantly affect the frequency of supplemental oxygen use, positive airway pressure support, or need for respiratory medications.In high-risk extremely low birth weight infants, stress dose hydrocortisone therapy after 10 days of age had no statistically significant effect on the incidence of death or neurodevelopmental impairment at 18-22 months. These results may inform the design and conduct of future clinical trials.ClinicalTrials.gov NCT00167544.

    Full Text Available It remains unclear why substantial variations in neurodevelopmental outcomes exist within small-for-gestational-age (SGA children. We prospectively compared 5-y neurodevelopmental outcomes across SGA etiological subgroups.Children born SGA (N = 1050 from U.S. Early Childhood Longitudinal Study-Birth Cohort (2001-2007 was divided into etiological subgroups by each of 7 well-established prenatal risk factors. We fit linear regression models to compare 5-y reading, math, gross motor and fine motor scores across SGA subgroups, adjusting for socio-demographic confounders.Compared to singleton SGA subgroup, multiple-birth SGA subgroup had lower mean reading (adjusted mean difference, -4.08 [95% confidence interval, -6.10, -2.06] and math (-2.22 [-3.61, -0.84] scores. These disadvantages in reading and math existed only among multiple-birth SGA subgroup without ovulation stimulation (reading, -4.50 [-6.64, -2.36]; math, -2.91 [-4.37, -1.44], but not among those with ovulation stimulation (reading, -2.33 [-6.24, 1.57]; math 0.63 [-1.86, 3.12]. Compared to singleton SGA subgroup without maternal smoking and inadequate gestational weight gain, singleton SGA subgroup with co-occurrence of maternal smoking and inadequate gestational weight gain (GWG had lower mean reading (-4.81 [-8.50, -1.12] and math (-2.95 [-5.51, -0.38] scores. These differences were not mediated by Apgar score.Multiple-birth SGA subgroups (vs. singleton SGA or singleton SGA subgroup with co-occurrence of smoking and inadequate GWG (vs. singleton SGA subgroup without maternal smoking and inadequate gestational weight gain have poorer cognitive development up to 5 y.

    Full Text Available Introduction: Neuroglycopaenia is recognised to be associated with abnormal neurodevelopmental outcomes in 26-44% of children with persistent congenital hyperinsulinism (P-CHI. The prevalence of abnormal neurodevelopment in transient CHI (T-CHI is not known. We have aimed to investigate abnormal neurodevelopment and associated factors in T-CHI and P-CHI. Materials and Methods: A cohort of children with CHI (n=67, age 2.5-5 years was assessed at follow up review and noted to have normal or abnormal (mild or severe neurodevelopmental outcomes for the domains of speech and language, motor and vision. Children were classified as P-CHI (n=33, if they had undergone surgery or remained on medical therapy, or T-CHI (n=34, if medical treatment for hypoglycaemia was stopped. Results: Overall, abnormal neurodevelopment was present in 26 (39% children with CHI, of whom 18 (69% were severe. Importantly, the incidence of abnormal neurodevelopment in T-CHI was similar to that in P-CHI (30% v 47% respectively, p=0.16. The prevalence of severe abnormal neurodevelopment in speech, motor and vision domains was similar in both T-CHI and P-CHI children. For this cohort, we found that the severity of disease (based upon maximal diazoxide dose, [odds ratio (95% confidence intervals 1.3 (1.1;1.5, p=0.03] and early presentation of CHI <7 days following birth [5.9 (1.3;27.8, p=0.02] were significantly associated with abnormal neurodevelopment. There was no significant association with gender, genotype or the histopathological basis of CHI. Conclusions: Abnormal neurodevelopment was evident in one third of children with both T-CHI and P-CHI, early presentation and severe CHI being risk factors. Early recognition and rapid correction of hypoglycaemia are advocated to avoid abnormal neurodevelopment in children with CHI.

    Premature birth is often associated with neurodevelopmental difficulties throughout childhood. In the first three years of life, the Bayley Scales of Infant and Toddler Development-Third Edition (Bayley-III) constitute one of the most used tools for assessing child development. Since Bayley-III original norms are based on United States (US) population, it remains uncertain whether their use in other countries (e.g., European) is appropriate. This research aimed to examine neurodevelopment of preterm infants and full-term infants, using Bayley-III US norms in comparison to Italian (IT) norms. Patterns of developmental outcomes for both infant groups were also explored. 104 preterm and 58 full-term infants were included in the study. Bayley-III was used for neurodevelopmental assessment at 1year of corrected age, considering both IT and US norms for scores computation. Comparing scores obtained with IT vs US norms, differences in means were all significant across five subscales (pdevelopment compared to IT norms. These findings emphasize the need to early detect children at risk for developmental delay and to plan early intervention. Copyright © 2017 Elsevier B.V. All rights reserved.

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

    Preterm infants commonly have transient hypothyroxinemia of prematurity after birth, which has been associated with deficits in general intellectual functioning, memory, attention, and academic achievement. However, research has predominantly focused on thyroxine levels in the first 2 weeks of life and outcomes are limited to the preschool period. Our objective was to evaluate the relationships between free thyroxine (fT₄) levels over the first 6 weeks after very preterm (VPT) birth with cognitive functioning and brain development at age 7 years.

    To evaluate the perinatal outcomes of newborns after premature rupture of membranes (PROM) at the term according to the timing of initial antibiotic administration. This is a retrospective, cohort study investigating perinatal outcomes of newborns in pregnant women with PROM at the term who were treated with ampicillin within or after 6 h from the PROM. Statistical analysis was performed using Student's t-test for continuous variables test and chi-square or for categorical data. The study involved 144 pregnant women with PROM and their newborns, a lower number received antibiotics after birth were in the group who received antibiotics within 6 h of PROM (26.4% versus 73.6%), the mediane values of C-reactive protein were lower (3.0 ± 2.9 mg/l versus 6.1 ± 7.3 mg/l; p < 0.001), their newborns remained shorter in hospital after birth (4.13 versus 4.94; p =0.023) and time between PROM and delivery was shorter (p < 0.001). In group who received prophylactic antibiotics after 6 h of the PROM had significantly higher frequency of infection in newborns (45.3% versus 15.4%), and higher number of chorioamnionitis (9.72% versus 3,47%) compared to group who received antibiotics within 6h. Timely usage of antibiotic prophylaxis and shorter time between PROM and delivery improve perinatal outcomes.

    To compare neurodevelopmental outcomes of HIV-exposed uninfected (HEU) and HIV-unexposed uninfected (HUU) infants in a peri-urban South African population. HEU infants living in Africa face unique biological and environmental risks, but uncertainty remains regarding their neurodevelopmental outcome. This is partly due to lack of well-matched HUU comparison groups needed to adjust for confounding factors. This was a prospective cohort study of infants enrolled at birth from a low-risk midwife obstetric facility. At 12 months of age, HEU and HUU infant growth and neurodevelopmental outcomes were compared. Growth was evaluated as WHO weight-for-age, length-for-age, weight-for-length and head-circumference-for-age Z-scores. Neurodevelopmental outcomes were evaluated using the Bayley scales of Infant Development III (BSID) and Alarm Distress Baby Scale (ADBB). Fifty-eight HEU and 38 HUU infants were evaluated at 11-14 months of age. Performance on the BSID did not differ in any of the domains between HEU and HUU infants. The cognitive, language and motor scores were within the average range (US standardised norms). Seven (12%) HEU and 1 (2.6%) HUU infant showed social withdrawal on the ADBB (P = 0.10), while 15 (26%) HEU and 4 (11%) HUU infants showed decreased vocalisation (P = 0.06). There were no growth differences. Three HEU and one HUU infant had minor neurological signs, while eight HEU and two HUU infants had macrocephaly. Although findings on the early neurodevelopmental outcome of HEU infants are reassuring, minor differences in vocalisation and on neurological examination indicate a need for reassessment at a later age. © 2017 John Wiley & Sons Ltd.

    Background Post-operative apnea is a complication in young infants. Awake-regional anesthesia (RA) may reduce the risk; however the evidence is weak. The General Anesthesia compared to Spinal anesthesia (GAS) study is a randomized, controlled, trial designed to assess the influence of general anesthesia (GA) on neurodevelopment. A secondary aim is to compare rates of apnea after anesthesia. Methods Infants ≤ 60 weeks postmenstrual age scheduled for inguinal herniorraphy were randomized to RA or GA. Exclusion criteria included risk factors for adverse neurodevelopmental outcome and infants born < 26 weeks’ gestation. The primary outcome of this analysis was any observed apnea up to 12 hours post-operatively. Apnea assessment was unblinded. Results 363 patients were assigned to RA and 359 to GA. Overall the incidence of apnea (0 to 12 hours) was similar between arms (3% in RA and 4% in GA arms, Odds Ratio (OR) 0.63, 95% Confidence Intervals (CI): 0.31 to 1.30, P=0.2133), however the incidence of early apnea (0 to 30 minutes) was lower in the RA arm (1% versus 3%, OR 0.20, 95%CI: 0.05 to 0.91, P=0.0367). The incidence of late apnea (30 minutes to 12 hours) was 2% in both RA and GA arms (OR 1.17, 95%CI: 0.41 to 3.33, P=0.7688). The strongest predictor of apnea was prematurity (OR 21.87, 95% CI 4.38 to 109.24) and 96% of infants with apnea were premature. Conclusions RA in infants undergoing inguinal herniorraphy reduces apnea in the early post-operative period. Cardio-respiratory monitoring should be used for all ex-premature infants. PMID:26001033

The objective of the present study was to evaluate the influence of intrauterine growth restriction and early extrauterine head growth on the neurodevelopmental outcome of monozygotic twins. Thirty-six monozygous twin pairs were evaluated at the corrected age of 12 to 42 months. Intrauterine growth restriction was quantified using the fetal growth ratio. The effects of birth weight ratio, head circumference at birth and current head circumference on mental and motor outcomes were estimated using mixed-effect linear regression models. Separate estimates of the between (interpair and within (intrapair effects of each measure on development were thus obtained. Neurodevelopment was assessed with the Bayley Scales of Infant Development, 2nd edition, by a psychologist blind to the exposure. A standardized neurological examination was performed by a neuropediatrician who was unaware of the exposures under investigation. After adjustment, birth weight ratio and head circumference at birth were not associated with motor or mental outcomes. Current head circumference was associated with mental but not with motor outcomes. Only the intrapair twin effect was significant. An increase of 1 cm in current head circumference of one twin compared with the other was associated with 3.2 points higher in Mental Developmental Index (95%CI = 1.06-5.32; P < 0.03. Thus, no effect of intrauterine growth was found on cognition and only postnatal head growth was associated with cognition. This effect was not shared by the co-twin.

    Comparative study of delivery mode and perinatal outcomes in women with premature rupture of membranes at term compared to those with intact membranes. A cross sectional survey of all deliveries in 39 hospitals in 3 geographic regions of mainland China from January 1 to December 31, 2011 was carried out to investigate the demographic data and delivery outcomes. In our analysis of 103 124 pregnancies, 14 073(13.6%) were complicated by premature rupture of membranes. Compared to those with intact membrane, the risks of postpartum hemorrhage, maternal complications and neonatal complications were increased significantly for women with premature rupture of membranes at term, especially the prevalence of neonatal respiratory distress syndrome(NRDS) and meconium aspiration syndrome. The risk of low Apgar (premature rupture of membranes at term. The adverse perinatal outcomes are slightly higher in women with term premature rupture of membranes than those with intact membrane.

    This study aimed to determine relationships between cerebral blood flow and neurodevelopmental outcomes in children with moderate to severe traumatic brain injury (TBI). Children with TBI, a Glasgow Coma Score of 8-12, and abnormal brain imaging were enrolled prospectively. Cerebral blood flow velocity (CBFV) was assessed within 24 h of trauma and daily thereafter through death, discharge, or hospital day 8, whichever came first. Twelve months from injury, participants completed neurodevelopmental testing. Sixty-nine patients were enrolled. Low flow velocities (flow velocities (± 2 SD around age/gender normal) were seen in 43% of participants (n = 30). High flow velocities (> 2 SD above age and gender normal with a Lindegaard ratio (LR)  2 SD above age/gender normal with LR ≥ 3) was identified in 28% (n = 19). Children with good outcomes based on GOS-E Peds scoring were more likely to have had normal flow velocity than other flow patterns. No other differences in neurodevelopmental outcomes were noted. Individual patient responses to TBI in terms of CBFV alterations were heterogeneous. Low flow was uniformly associated with a poor outcome. Patients with good outcomes were more likely to have normal flow. This suggests CBFV may serve as a prognostic indicator in children with TBI. Future studies are needed to determine if aberrant CBFVs are also a therapeutic target.

    During the past decade, laser photoablation has supplanted cryotherapy as the standard treatment for threshold retinopathy of prematurity (ROP). We evaluated the progression and the complication rate in a cohort of infants with threshold ROP treated with a confluent technique. We retrospectively studied 47 patients with ROP (91 eyes), treated with confluent diode laser photoablation. Four main outcomes were evaluated: (1) the rate of progression, (2) the frequency of laser retreatment, (3) postoperative complications, and (4) postoperative refractive error. A mean of 1943 +/- 912 laser burns were administered in a confluent pattern to 91 eyes with threshold ROP. Progression to stage 4 or 5 disease occurred in 13 of 29 eyes (44.8%) with zone I and posterior zone II and in 2 of 51 eyes (3.9%) with anterior zone II ROP (P =.01). Eyes with anterior zone II ROP that received more than or equal to 2000 burns progressed more than those that received fewer than 2000 burns. Only 1 eye (1%) needed a supplemental laser treatment. Postoperative complications included corneal edema (2.3%), anterior segment ischemia (2.3%), vitreous hemorrhage (7.9%), posterior synechiae (2.3%), cataract (4.9%), and macular ectopia (12%). The mean spherical equivalent at the last follow-up was -4.52 +/- 5.63 D. In our series, infants received more laser burns than infants reported in the literature receiving scatter or near-confluent treatment. While confluent treatment almost eliminated supplemental treatment, it was associated with a similar rate of progression and complications as has been reported with other patterns of laser treatment.

    Very preterm-born neonates (24-32 weeks of gestation) are exposed to stressful and painful procedures during neonatal intensive care. Analgesic and sedation therapies are essential, and opiates and benzodiazepines are commonly used. These medications may negatively impact brain development. The hippocampus may be especially vulnerable to the effects of pain and analgesic and/or sedative therapies and contribute to adverse outcomes. The effect of invasive procedures and analgesic-sedative exposure on hippocampal growth was assessed, as was that of hippocampal growth on neurodevelopmental outcome. A total of 138 neonates (51% male, median gestational age = 27.7 weeks) underwent magnetic resonance imaging and diffusion tensor imaging (DTI) scans, early in life (postmenstrual age [PMA] = 32.3 weeks) and at term-equivalent age (PMA = 40.2 weeks). Volumes and DTI measures of axial diffusivity, radial diffusivity, and mean diffusivity (MD) were obtained from the hippocampus. Cognitive, language, and motor abilities were assessed using the Bayley Scales of Infant Development-III at 18.7 months median corrected age. Models testing the association of invasive procedures with hippocampal volumes and DTI measures accounted for birth gestational age, sex, PMA, dose of analgesics/sedatives (fentanyl, morphine, midazolam), mechanical ventilation, hypotension, and surgeries. Total midazolam dose predicted decreased hippocampal volumes (β = -1.8, p 0.5 each). Lower cognitive scores were associated with hippocampal growth (β = -0.31, p = 0.003), midazolam dose (β = -0.27, p = 0.03), and surgery (β = -8.32, p = 0.04). Midazolam exposure was associated with macro- and microstructural alterations in hippocampal development and poorer outcomes consistent with hippocampal dysmaturation. Use of midazolam in preterm neonates, particularly those not undergoing surgery, is cautioned. © 2016 American Neurological Association.

    Non-right handedness (NRH) is reportedly more common in very preterm (VPT; children compared with term-born peers, but it is unclear whether neonatal brain injury or altered brain morphology and microstructure underpins NRH in this population. Given that NRH has been inconsistently reported to be associated with cognitive and motor difficulties, this study aimed to examine associations between handedness and neurodevelopmental outcomes in VPT 7-year-olds. Furthermore, the relationship between neonatal brain injury and integrity of motor tracts (corpus callosum and corticospinal tract) with handedness at age 7 years in VPT children was explored. One hundred seventy-five VPT and 69 term-born children completed neuropsychological and motor assessments and a measure of handedness at 7 years' corrected age. At term-equivalent age, brain injury on MRI was assessed and diffusion tensor measures were obtained for the corpus callosum and posterior limb of the internal capsule. There was little evidence of stronger NRH in the VPT group compared with term controls (regression coefficient [b] -1.95, 95% confidence interval [-5.67, 1.77]). Poorer academic and working memory outcomes were associated with stronger NRH in the VPT group. While there was little evidence that neonatal unilateral brain injury was associated with stronger NRH, increased area and fractional anisotropy of the corpus callosum splenium were predictive of stronger NRH in the VPT group. VPT birth may alter the relationship between handedness and academic outcomes, and neonatal corpus callosum integrity predicts hand preference in VPT children at school age.

    Neurodevelopmental and behavioral assessment of very low birth weight babies (VLBW) at corrected age (CA) of 2 years. 127, 110, 99 and 101 babies ≤34 weeks and ≤1500 g were followed at CA of 3, 6, 9, 12 months respectively for developmental and neurological assessment. DASII (Developmental assessment scale for Indian infants) was used at CA of 18 months and preschool behavioural checklist (PBCL) at CA 2 years. Of 101 VLBW babies available for follow up at CA 1 year, 3 (3%) babies had Cerebral Palsy (CP) and 3% (n = 3) had suspect abnormality (mild hypotonia), 11% (n = 11) had gross motor and 8% (n = 8) had language abnormality. Their mean mental (MeDQ) and motor (MoDQ) quotients were 80.4 ± 10.7 and 77.2 ± 13.3 and a score of < 70 was found in 17% (MeDQ) and 25.7% (MoDQ) VLBW babies. High PBCL score (mean 16.8 ± 5.4) was seen in 84%VLBW babies. On subgroup analysis, 2 babies (5%) in subgroup1 ( n = 54, ≤1200 g,) and 1 (1.6%) in subgroup 2 (n = 78, 1201-1500 g) had CP. Twelve (29%) in subgroup 1 had significant language delay (p = 0.004) as compared to 4 (15%) in subgroup 2 at 1 year. BSID and PBCL scores were comparable. Amongst ELBW babies (<1000 g), 6.6% (n = 1) had CP, 25% (n = 3) and 42% (n = 5) had low MeDQ and MoDQ respectively and all of them had high PBCL score. AGA and SGA had similar outcome. VLBW babies need close and longer follow up due to high risk of neurodevelopmental and behavioral abnormality.

    To evaluate the long-term neurodevelopmental outcome in children who developed twin anemia-polycythemia sequence (TAPS) after fetoscopic laser surgery for twin-twin transfusion syndrome (TTTS). Neurological, motor and cognitive development was assessed in a consecutive cohort of TTTS survivors treated with laser surgery between 2004 and 2011 and complicated by post-laser TAPS. Primary outcome was neurodevelopmental impairment, a composite outcome including any of the following: cerebral palsy, bilateral deafness, blindness, severe motor and/or cognitive developmental delay (>2 SD below the mean). A risk analysis on cognitive outcome was performed. During the study period, 33/306 (11%) monochorionic twin pairs developed TAPS after laser surgery for TTTS. Survival was 53/66 (80%). Long-term outcome was assessed in 47/53 (89%) children. The incidence of neurodevelopmental impairment was 4/47 (9%), occurring in one donor (1/20; 5%) and three recipients (3/27; 11%) (P=0.63). Mild-to-moderate cognitive delay, i.e. scores below 85, was detected in 8/47 (17%) children. Risk factors for low cognitive scores were low gestational age at birth (P=0.02) and low birth weight (P<0.01). The lowest cognitive scores were detected in the subgroup of TAPS survivors treated with intrauterine transfusion (median score, 82.5). Neurodevelopmental impairment and cognitive delay were found in almost one in five children surviving post-laser TAPS. Better treatment and, ideally, prevention of this complication after laser treatment for TTTS is urgently needed. Copyright © 2014 ISUOG. Published by John Wiley & Sons Ltd.

    To characterize neurodevelopmental outcomes after fetal aortic valvuloplasty for evolving hypoplastic left heart syndrome and determine the risk factors for adverse neurodevelopment. Questionnaires were mailed to families of children who underwent fetal aortic valvuloplasty from 2000 to 2012, and medical records were reviewed retrospectively. The primary outcome was the General Adaptive Composite score of the Adaptive Behavior Assessment System Questionnaire-Second Edition. Other questionnaires included the Behavior Assessment System for Children, Behavior Rating Inventory of Executive Function, Ages and Stages, and Pediatric Quality of Life Inventory. Among 69 eligible subjects, 52 (75%) completed questionnaires at median age of 5.5 (range 1.3-12) years; 30 (58%) had biventricular status circulation. The General Adaptive Composite mean score (92 ± 17) was lower than population norms (P Children, Behavior Rating Inventory of Executive Function, Ages and Stages, Pediatric Quality of Life Inventory), most subscale scores for patients with biventricular and single ventricular status were similar. Children who underwent fetal aortic valvuloplasty have neurodevelopmental delay, similar to patients with hypoplastic left heart syndrome without fetal intervention. Achievement of biventricular circulation was not associated with better outcomes. We infer that innate patient factors and morbidity during infancy have the greatest effect on neurodevelopmental outcomes. Copyright © 2017 Elsevier Inc. All rights reserved.

    Limited human data are available to assess the association between prenatal mercury vapor (Hg⁰)) exposure from maternal dental amalgam restorations and neurodevelopment of children. We evaluated the association between maternal dental amalgam status during gestation and children's neurodevelopmental outcomes at 5 years in the Seychelles Child Development Nutrition Study (SCDNS). Maternal amalgam status was determined prospectively in a longitudinal cohort study examining the associations of prenatal exposure to nutrients and methylmercury (MeHg) with neurodevelopment. A total of 236 mother-child pairs initially enrolled in the SCDNS in 2001 were eligible to participate. Maternal amalgam status was measured as number of amalgam surfaces (the primary metric) and number of occlusal points. The neurodevelopmental assessment battery was comprised of age-appropriate tests of cognitive, language, and perceptual functions, and scholastic achievement. Linear regression analysis controlled for MeHg exposure, maternal fatty acid status, and other covariates relevant to child development. Maternal amalgam status evaluation yielded an average of 7.0 surfaces (range 0-28) and 11.0 occlusal points (range 0-40) during pregnancy. Neither the number of maternal amalgam surfaces nor occlusal points were associated with any outcome. Our findings do not provide evidence to support a relationship between prenatal exposure to Hg⁰ from maternal dental amalgam and neurodevelopmental outcomes in children at 5 years of age. © 2013.

    The objective of this study was to evaluate the early changes in serial serum levels of copeptin and neuron-specific enolase (NSE) in neonates diagnosed with birth asphyxia, and to determine whether these biomarkers measured in the first 168 hours after birth are predictive of long-term neurodevelopmental outcome. Copeptin and NSE levels were measured from serum samples collected 6, 12, 24, 48, 72, and 168 hours after birth from 75 term neonates diagnosed with hypoxic-ischemic encephalopathy (HIE) and treated with therapeutic hypothermia for 72 hours. In addition, serum copeptin levels after birth were measured from 10 HIE diagnosed neonates, who were randomized to the normothermic arm of the TOBY cohort. All neonates underwent neurodevelopmental assessment using the Bayley Scales of Infant and Toddler Development-II at two years of age. Copeptin levels were highest at 6 hours after birth and steadily decreased, whereas the highest NSE levels were measured at 24 hours after birth. The biomarker levels correlated with blood-gas parameters (base excess, pH and lactate) at 6 and 12 hours after birth. Copeptin and NSE levels in the early postnatal period were significantly higher in neonates with poor outcome compared to those with favorable outcome at two years of age. Furthermore, in the TOBY cohort, copeptin levels were significantly lower in hypothermic compared to normothermic neonates. To conclude, copeptin and NSE measured in the early postnatal period are potential prognostic biomarkers of long-term neurodevelopmental outcome in term neonates diagnosed with HIE and treated with therapeutic hypothermia.

Prolonged mechanical ventilation and parenteral nutrition were identified as independent perinatal risk factors. The prognostic value of the TEA-MRI score was rather limited in this well-performing cohort.

    Objective To investigate the outcomes following prolonged empirical antibiotic administration to premature infants in the first week of life, concluding subsequent late onset sepsis (LOS), necrotizing enterocolitis (NEC), and death. Study design Study infants were ≤32 weeks gestational age and ≤ 1500 grams birth weight who survived free of sepsis and NEC for 7 days. Multivariable logistic regression was conducted to determine independent relationships between prolonged initial empirical antibiotic therapy (≥ 5 days) and study outcomes controlling for birth weight, gestational age, race, prolonged premature rupture of membranes, days on high frequency ventilation in 7 days, and the amount of breast milk received in the first 14 days of life. Results Of the 365 premature infants surviving 7 days free of sepsis or NEC, 36% received prolonged initial empirical antibiotics, which was independently associated with subsequent outcomes: LOS (odds ratio [OR] 2.45, 95% confidence interval [CI] 1.28–4.67) and the combination of LOS, NEC, or death (OR 2.66, 95% CI 1.12–6.3). Conclusions Prolonged administration of empirical antibiotics to premature infants with sterile cultures in the first week of life is associated with subsequent severe outcomes. Judicious restriction of antibiotic use should be investigated as a strategy to reduce severe outcomes for premature infants. PMID:21784435

    Purpose To report two successful antagonist IVF cycles; one ending up with pregnancy despite premature luteinization (case 1, aged 35 years), and the other with the retrieval of high quality oocytes despite premature ovulation (case 2, aged 39 years). Methods Serum LH was 36 and 47 IU/L on cycle day 7 before antagonist administration, which was then brought to 6.94 and 3.92 IU/L by antagonist administration, and kept below these levels throughout the remaining stimulation in case 1 and 2 respectively. Serum progesterone was 1.42 and 5.5 ng/mL on the day of hCG respectively. Ten metaphase II (MII) oocytes were harvested wherein 3 grade A embryos were transferred in case 1, and seven good quality MII oocytes were retrieved wherein six embryos were cryopreserved in case 2. Conclusions More precise cut thresholds for both LH and progesterone are necessary for accurate prediction of the cycle outcomes. PMID:19224360

    Surviving extremely low-birth-weight infants are at risk of severe neurodevelopmental disability. Transfusion with packed red cells is almost universal in the care of these infants, but the hemoglobin threshold at which these transfusions should be given is unclear. Different clinical trials of restrictive (low hemoglobin) versus liberal (high hemoglobin) thresholds have addressed either neurodevelopmental outcomes at 18-21 months of corrected gestational age or psychological tests and brain imaging at 8-15 years of age. Early follow-up shows differences in cognitive outcome favoring the liberal strategy, but as a post hoc secondary outcome. The childhood studies favor the restrictive strategy, but include major methodological problems of secondary recruitment. No firm conclusion can be reached, other than to report that serious adverse effects may be attributable to one or other of these strategies, that prudent practice is to remain within trial protocols, and that further redesigned clinical trials are required.

    The use of air for the initial resuscitation of newborn infants has been shown to reduce neonatal mortality. However, a precise estimate of the neurodevelopmental status upon follow-up of infants resuscitated in air is lacking. To perform a meta-analysis of all studies reporting resuscitation of newborn infants with air or 100% oxygen that included follow-up data. Bibliographic databases were searched. In addition, we estimated the effect of loss to follow-up on our analysis of abnormal neurodevelopmental outcome. We identified 10 studies in which newborn infants had been randomly or quasi-randomly assigned to resuscitation with air or 100% oxygen. Three of these 10 studies had available follow-up data. A total of 678 infants were enrolled at centers that performed follow-up of these infants. Of these, 113 died, leaving 565 infants potentially eligible for follow-up. A total of 414 children were evaluated (73% of eligible children; 195 resuscitated with air and 219 with 100% oxygen). In the air group, 12.8% of infants had an abnormal neurodevelopmental outcome, compared with 10.5% in the 100% oxygen group [typical relative risk (RR) 1.24, 95% confidence interval 0.73-2.10]. This is consistent with an RR of abnormal development as low as 0.41 or as high as 2.28. Long-term follow-up did not detect any significant differences in these two groups regarding abnormal development. However, the results are imprecise and could be consistent with significant harm or benefit. Copyright © 2012 S. Karger AG, Basel.

    Active perinatal care increases the rate of survival of extremely preterm infants, but there are concerns that improved survival might increase the rate of disabled survivors. To determine the neurodevelopmental outcomes of a national cohort of children 6.5 years of age who had been born extremely preterm (children were assessed and compared with matched controls who had been born at term. Comparison estimates were adjusted for demographic differences. Assessments ended in February 2014, and analysis started thereafter. Cognitive ability was measured with the fourth edition of the Wechsler Intelligence Scale for Children (WISC-IV), and the mean (SD) scores of the children who had been born extremely preterm were compared with those of the controls. Clinical examinations and parental questionnaires were used for diagnosis of cerebral palsy, hearing and vision impairments, and cognition for the children who were not assessed with the WISC-IV. Of 486 eligible infants who were born extremely preterm, 441 (90.7%) were assessed at 6.5 years of age (59 by medical record review only) alongside 371 controls. The adjusted mean (SD) full-scale WISC-IV score was 14.2 (95% CI, 12.1-16.3) points lower for children who had been born extremely preterm than for controls. Cognitive disability was moderate for 18.8% of extremely preterm children and 2.2% of controls (P children and 0.3% of controls (P children and 0.0% of controls (P blindness was observed in 2.0% of extremely preterm children and 0.0% of controls (P children and 0.5% of controls (P = .07). Overall, 36.1% (95% CI, 31.7%-40.6%) of extremely preterm children had no disability, 30.4% (95% CI 26.3%-34.8%) had mild disability, 20.2% (95% CI, 16.6%-24.2%) had moderate disability, and 13.4% (95% CI, 10.5%-16.9%) had severe disability. For extremely preterm children, moderate or severe overall disability decreased with gestational age at birth (adjusted odds ratio per week, 0.65 [95% CI, 0.54-0.79]; P

    The purpose of this study was to assess the need and timing of extracorporeal membrane oxygenation in relation to congenital diaphragmatic hernia repair as modifiers of short-term neurodevelopmental outcomes. Retrospective study. A specialized tertiary care center. Between June 2004 and February 2016, a total of 212 congenital diaphragmatic hernia survivors enrolled in our follow-up program. Neurodevelopmental outcome was assessed at a median age of 22 months (range, 5-37) using the Bayley Scales of Infant Development, third edition. Fifty patients (24%) required extracorporeal membrane oxygenation support. Four patients (8%) were repaired prior to cannulation, 25 (50%) were repaired on extracorporeal membrane oxygenation, and 21 (42%) were repaired after decannulation. None. Children with congenital diaphragmatic hernia, who required extracorporeal membrane oxygenation scored on average 4.6 points lower on cognitive composite (p = 0.031) and 9.2 points lower on the motor composite (p < 0.001). Language scores were similar between groups. Mean scores for children with congenital diaphragmatic hernia repaired on extracorporeal membrane oxygenation were significantly lower for cognition (p = 0.021) and motor (p = 0.0005) outcome. Language scores were also lower, but did not reach significance. A total of 40% of children repaired on extracorporeal membrane oxygenation scored below average in all composites, whereas only 9% of the non-extracorporeal membrane oxygenation, 4% of the repaired post-extracorporeal membrane oxygenation, and 25% of the repaired pre-extracorporeal membrane oxygenation patients scored below average across all domains. Only 20% of congenital diaphragmatic hernia survivors repaired on extracorporeal membrane oxygenation support scored within the average range for all composite domains. Duration of extracorporeal membrane oxygenation support was not associated with a higher likelihood of adverse cognitive (p = 0.641), language (p = 0.147), or

    Full Text Available OBJECTIVE: To evaluate the contribution of sequential cranial ultrasound (cUS and term-equivalent age magnetic resonance imaging (TEA-MRI including diffusion weighted imaging (DWI to the early prognosis of neurodevelopmental outcome in a cohort of very preterm infants (gestational age [GA] <31 weeks. STUDY DESIGN: In total, 93 preterm infants (median [range] GA in weeks: 28.3 [25.0-30.9] were enrolled in this prospective cohort study and underwent early and term cUS as well as TEA-MRI including DWI. Early cUS abnormalities were classified as normal, mild, moderate or severe. Term cUS was evaluated for ex-vacuo ventriculomegaly (VM and enlargement of the extracerebral cerebrospinal fluid (eCSF space. Abnormalities on T1- and T2-weighted TEA-MRI were scored according to Kidokoro et al. Using DWI at TEA, apparent diffusion coefficients (ADCs were measured in four white matter regions bilaterally and both cerebellar hemispheres. Neurodevelopmental outcome was assessed at two years' corrected age (CA using the Bayley Scales of Infant and Toddler Development, third edition. Linear regression analysis was conducted to explore the correlation between the different neuroimaging modalities and outcome. RESULTS: Moderate/severe abnormalities on early cUS, ex-vacuo VM and enlargement of the eCSF space on term cUS and increased cerebellar ADC values on term DWI were independently associated with worse motor outcome (p<.05. Ex-vacuo VM on term cUS was also related to worse cognitive performance at two years' CA (p<.01. CONCLUSION: These data support the clinical value of sequential cUS and recommend repeating cUS at TEA. In particular, assessment of moderate/severe early cUS abnormalities and ex-vacuo VM on term cUS provides important prognostic information. Cerebellar ADC values may further aid in the prognostication of gross motor function.

    Maternal obesity is associated with increased systemic inflammation and an increased risk of preterm premature rupture of membranes. There is an established association between an inflammatory intrauterine environment and adverse neonatal outcomes that is independent of gestational age and mediated by the fetal inflammatory response. It is unknown whether the maternal systemic inflammation that is present in obese women influences the intrauterine environment and predisposes the fetus to adverse neonatal outcomes after preterm premature rupture of membranes. The purpose of this study was to determine whether maternal obesity is associated with adverse neonatal outcomes in pregnancies that are complicated by preterm premature rupture of membranes. This was a secondary analysis of the Maternal-Fetal Medicine Units Network Randomized Clinical Trial on the Beneficial Effects of Antenatal Magnesium Sulfate. Women with singleton pregnancies that were affected by preterm premature rupture of membranes who delivered live-born infants between 24 + 0 and 33 + 6 weeks of gestation were included. An adverse neonatal outcome was defined as a composite outcome of neonatal death, severe necrotizing enterocolitis, respiratory distress syndrome, sepsis, or severe intraventricular hemorrhage. The rates of the composite outcome were compared between obese (body mass index, ≥30 kg/m(2)) and nonobese women. Multivariable logistic regression was used to evaluate the independent effect of obesity on neonatal outcomes. Magnesium sulfate administration, steroid administration, maternal diabetes mellitus, gestational age at delivery, indomethacin exposure, birthweight, and chorioamnionitis were all considered as possible covariates in the multivariable regression models. Three hundred twenty-five of the 1288 women (25.2%) who were included were obese, and 202 of these women (62.2%) had neonates with adverse outcomes. In univariable analysis, maternal prepregnancy obesity was associated

    Morbidity attributable to hypoxic-ischaemic injury (HIE) in the perinatal period remains problematic, and timely and accurate assessment of the degree of injury is required for clinical management and prognosis. Conventional MR sequences typically appear normal in the first 48 h post HIE. While diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) maps register the injury earlier, perhaps within the first 24 h, it has been suggested that there may be a propensity at that early stage to underestimate the lesion severity or extent. To assess whether MR imaging that included DWI, measured ADC values and T1- and T2-weighted sequences ultimately correlated with either neurodevelopmental outcome or with late MR imaging at 2 years of age. In addition, we wished to compare the performance of MR imaging with cranial US imaging. All infants presenting with HIE who had an MRI within 10 days of life were eligible for enrollment and subsequently underwent a full neurodevelopmental assessment at 2 years of age. All children underwent repeat MRI at this time. All neonates had at least one cranial US study. The US findings were categorized as normal, abnormalities confined to the cerebral cortex and subcortical white matter, isolated central grey matter hyperechogenicity, and central hyperechogenicity combined with cerebral cortical/subcortical changes. All MRI studies were retrospectively reviewed by three radiologists. The patterns of injury on the early DWI and ADC maps and early T1- and T2-W studies were recorded as diffuse, central, watershed or atypical. The patterns of signal abnormality were assessed using a scoring system that yielded four separate scores [basal ganglia (BG), watershed (W), BG/W and summation (S)] for the three sets of images, a total of 12 scores in all. The appearance of the posterior limb of the internal capsule (PLIC) on T1-W inversion recovery sequences and of the corpus callosum on all sequences was also documented. After

    Previous studies have demonstrated that discriminative learning is facilitated when a particular outcome is associated with each relation to be learned. When this training procedure is applied (the differential outcome procedure; DOP), learning is faster and more accurate than when the more common non-differential outcome procedure is used. This enhancement of accuracy and acquisition has been called the differential outcome effect (DOE). Our primary purpose in the present study was to explore the DOE in children born with great prematurity performing a discriminative learning task (Experiment 1) or a delayed visuospatial recognition task (Experiment 2). In Experiment 1, participants showed a faster learning and a better performance when differential outcomes were used. In Experiment 2, a significant DOE was also observed. That is, premature children performed the visuospatial recognition task better when they received differential outcomes following their correct responses. By contrast, the overall performance of full-term children was similar in both differential and non-differential conditions. These results are first to show that the DOP can enhance learning of conditional discriminations and recognition memory in children born prematurely with very low birth-weight.

    To determine the long-term safety and outcomes of mesenchymal stem cells (MSCs) for bronchopulmonary dysplasia in premature infants enrolled in a previous phase I clinical trial up to 2 years of corrected age (CA). We assessed serious adverse events, somatic growth, and respiratory and neurodevelopmental outcomes at visit 1 (4-6 months of CA), visit 2 (8-12 months of CA), and visit 3 (18-24 months of CA) in a prospective longitudinal follow-up study up to 2 years' CA of infants who received MSCs (MSC group). We compared these data with those from a historical case-matched comparison group. One of 9 infants in the MSC group died of Enterobacter cloacae sepsis at 6 months of CA, the remaining 8 infants survived without any transplantation-related adverse outcomes, including tumorigenicity. No infant in the MSC group was discharged with home supplemental oxygen compared with 22% in the comparison group. The average rehospitalization rate in the MSC group was 1.4/patient because of respiratory infections during 2 years of follow-up. The mean body weight of the MSC group at visit 3 was significantly higher compared with that of the comparison group. No infant in the MSC group was diagnosed with cerebral palsy, blindness, or developmental delay; in the comparison group, 1 infant was diagnosed with cerebral palsy and 1 with developmental delay. Intratracheal transplantation of MSCs in preterm infants appears to be safe, with no adverse respiratory, growth, and neurodevelopmental effects at 2 years' CA. ClinicalTrials.gov: NCT01632475.

    The aim of this study was to identify adverse neonatal outcomes and identifies the predictors of adverse neonatal outcomes in premature rupture of membranes before 26 weeks. Data were collected between January 2005 and December 2011 from all pregnant women who presented preterm premature rupture of membranes (PPROM) between 18 and 26 complete weeks of gestation and were admitted to one of three Brazilian institutes. The adverse outcomes included mortality or the development of a severe morbidity during the length of stay in the neonatal intensive care unit (NICU). The descriptive statistics of the population were reported. A multiple logistic regression was performed for each predictor of neonatal adverse outcomes. The area under the receiver operating characteristics curves for the birth weight was calculated. Composite adverse outcomes during the NICU stay occurred in 82.1% (n = 23) of the cases and included 33 (54%) neonatal deaths, 19 (67.8%) cases of retinopathy of prematurity (ROP), 13 (46.4%) cases of pulmonary hypoplasia (BPD), 8 (28.5%) cases of periventricular-intraventricular hemorrhage (PIH) and 3 (10.7%) cases of periventricular leukomalacia (PVL). Only 17.8% (n = 5) of the neonates survived without morbidity. The area under the curve for the birth weight was 0.90 (95% IC: 0.81-0.98) for the prediction of mortality. PPROM before 26 weeks has a high morbidity and mortality, and the significant predictors of neonatal mortality and adverse outcomes were antibiotic prophylaxis, latency period, GA at birth and birth weight. Nevertheless, the only independent significant predictor of survival rate was birth weight.

    Active perinatal care increases survival of extremely preterm infants; however, improved survival might be associated with increased disability among survivors. To determine neurodevelopmental outcome in extremely preterm children at 2.5 years (corrected age). Population-based prospective cohort of consecutive extremely preterm infants born before 27 weeks of gestation in Sweden between 2004 and 2007. Of 707 live-born infants, 491 (69%) survived to 2.5 years. Survivors were assessed and compared with singleton control infants who were born at term and matched by sex, ethnicity, and municipality. Assessments ended in February 2010 and comparison estimates were adjusted for demographic differences. Cognitive, language, and motor development was assessed with Bayley Scales of Infant and Toddler Development (3rd edition; Bayley-lll), which are standardized to mean (SD) scores of 100 (15). Clinical examination and parental questionnaires were used for diagnosis of cerebral palsy and visual and hearing impairments. Assessments were made by week of gestational age. At a median age of 30.5 months (corrected), 456 of 491 (94%) extremely preterm children were evaluated (41 by chart review only). For controls, 701 had information on health status and 366 had Bayley-lll assessments. Mean (SD) composite Bayley-III scores (cognition, 94 [12.3]; language, 98 [16.5]; motor, 94 [15.9]) were lower than the corresponding mean scores for controls (cognition, 104 [10.6]; P Cognitive disability was moderate in 5% of the extremely preterm group vs 0.3% in controls (P blindness (0.9% vs 0%; P = .02), and for hearing impairment (moderate and severe, 0.9% vs 0%; P = .02, respectively). Overall, 42% (99% CI, 36%-48%) of extremely preterm children had no disability, 31% (99% CI, 25%-36%) had mild disability, 16% (99% CI, 12%-21%) had moderate disability, and 11% (99% CI, 7.2%-15%) had severe disability. Moderate or severe overall disability decreased with gestational age at birth (22 weeks

    Despite widespread use of fetal heart rate monitoring, the timing of injury in hypoxic-ischemic encephalopathy (HIE) remains unclear. Our aim was to examine fetal heart rate patterns during labor in infants with clinical and electroencephalographic (EEG) evidence of HIE and to relate these findings to neurodevelopmental outcome. Timing of onset of pathological cardiotocographs (CTGs) was determined in each case by two blinded reviewers and related to EEG grade at birth and neurological outcome at 24 months. CTGs were available in 35 infants with HIE (17 mild, 12 moderate, 6 severe on EEG). Admission CTGs were normal in 24\\/35 (69%), suspicious in 8\\/35 (23%), and pathological in 3\\/35 (8%). All CTGs developed nonreassuring features prior to delivery. Three patterns of fetal heart rate abnormalities were seen: group 1, abnormal CTGs on admission in 11\\/35 (31%); group 2, normal CTGs on admission with gradual deterioration to pathological in 20\\/35 cases (57%); and group 3, normal CTGs on admission with acute sentinel events in 4\\/35 (11.5%). The median (interquartile range) duration between the development of pathological CTGs and delivery was 145 (81, 221) minutes in group 2 and 22 (12, 28) minutes in group 3. There was no correlation between duration of pathological CTG trace and grade of encephalopathy (R = 0.09, P = 0.63) or neurological outcome (P = 0.75). However, the grade of encephalopathy was significantly worse in group 3 (P = 0.001), with a trend to worse outcomes. The majority of infants with HIE have normal CTG traces on admission but develop pathological CTG patterns within hours of delivery. More severe encephalopathy was associated with normal admission CTG and acute sentinel events shortly before delivery.

    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.

We describe the magnetic resonance imaging (MRI findings of two patients with neonatal-onset UCDs (argininosuccinic aciduria and citrullinemia at presentation and at 2-year follow-up, and present a review of the literature on neuroimaging in this age-group. We observed two potentially significant distinct patterns of cerebral involvement on MRI: (1 a central and focal pattern of involvement limited to the basal ganglia, perirolandic regions, and internal capsule; and (2 diffuse involvement of the cerebral cortex, internal capsule, basal ganglia, and variably thalami and brain stem. Patients with more diffuse findings tended to have higher serum glutamine peaks and worse neurological outcomes, while those with central involvement, aggressive acute management, and early liver transplantation tended to have better outcomes. We propose that MRI imaging of the brain may have prognostic value following presentation with neonatal UCDs, particularly in identifying patients at risk for poor outcome. The role and timing of follow-up neuroimaging is currently unclear. Further collaborative studies are necessary to evaluate whether patterns of MRI findings vary with specific UCD

    This study was undertaken to assess contemporary outcomes in pregnancies managed expectantly after extremely preterm premature (< or =24 weeks) premature rupture of the membranes (EPPROM). We queried antepartum and ultrasound databases for patients with EPPROM. Data on pregnancy outcome and short-term neonatal outcomes were collected. Forty-six patients with EPPROM were studied. Patients were hospitalized at 24 weeks' gestation and given antibiotics and antenatal steroids. Median gestational age at PPROM was 22.0 weeks (range 16.9-24 weeks); 43 (93%) elected expectant management, 2 of whom later had an intrauterine fetal death. Median latency period to delivery was 13 days (range 0-96 days), with mean gestational age at delivery of 25.8+/-3.4 weeks. Overall survival was 47% (27 of 57 infants), after a median hospital stay of 71 days (range 17-209 days). Ten (37%) of the survivors have serious sequelae. Although significant pregnancy prolongation after previable PPROM occurs in many cases, neonatal outcomes remain poor.

    To investigate the long-term impact of early-term birth (37-38 weeks' gestation) relative to full-term birth (≥39 weeks' gestation) on neurodevelopmental and psychiatric outcomes in adolescents with single-ventricle congenital heart disease (CHD). This cross-sectional cohort study analyzed retrospective medical records from full term adolescents with single-ventricle CHD who underwent the Fontan procedure. Participants underwent neurodevelopmental and psychiatric evaluations, as well as structural brain magnetic resonance imaging. Early-term born adolescents were compared with full-term born adolescents using regression models with adjustments for family social status, birth weight, and genetic abnormality status. Medical and demographic risk factors were examined as well. Compared with the full-term group (n = 100), adolescents born early term (n = 33) scored significantly worse on daily-life executive functions, as measured by the Behavior Rating Inventory of Executive Function parent-report (mean scores: early term, 62.0 ± 10.9; full-term, 55.6 ± 12.2; P = .009) and self-report (P = .02) composites. Adolescents born early term were more likely than those born full term to have a lifetime attention-deficit/hyperactivity disorder (ADHD) diagnosis (early term, 55%; full term, 26%; P = .001). The early-term group also displayed greater psychiatric symptom severity, as indicated by the clinician-reported Brief Psychiatric Rating Scale (mean score: early term, 16.1 ± 8.6; full-term, 12.5 ± 8.2; P = .007). Early-term birth is associated with greater prevalence of executive dysfunction, ADHD diagnosis, and psychiatric problems in adolescents with single-ventricle CHD. Early-term birth should be included as a potential risk factor in the algorithm for closer developmental surveillance in CHD. Copyright © 2016 Elsevier Inc. All rights reserved.

    This prospective cohort study evaluated whether the cognitive development, neurological condition, anthropometrics and blood pressure of 4-year-old IVF twins differed from those of 4-year-old IVF singletons; 103 IVF singletons and 48 IVF twins born after conventional IVF treatment were included. Primary outcome was total intelligence quotient (IQ). Secondary outcomes were minor neurological dysfunction, anthropometrics and blood pressure. Unadjusted analyses found that the total IQ score of twins was lower than that of singletons, with a mean difference of -5.4 (-9.7 to -1.0). Weight (singletons: 18.6 [18.1 to 19.1] kg; twins: 16.9 [16.0 to 17.9] kg) and height (singletons: 108.8 [107.9 to 109.8] cm; twins: 105.9 [104.0 to 107.7] cm) of twins were lower than those of singletons (mean values [95% CI]). All differences disappeared after adjusting for mediators and confounders. Neurological outcome, systolic and diastolic blood pressure of twins and singletons were similar. Four-year-old IVF twins had a lower total IQ (-5.4 points), lowerbodyweight (-1.7 kg) and were shorter (-2.9 cm) than 4-year-old IVF singletons. After adjustment, the adverse twin effect disappeared, implying that increased risk for impaired health and development in twins also holds true for IVF twins, and is not altered by IVF.

    Choline is an essential nutrient that is found in many food sources and plays a critical role in the development of the central nervous system. Animal studies have shown that choline status pre- and postnatally can have long-lasting effects on attention and memory; however, effects in human subjects have not been well studied. The aim of the present study was to examine the association between plasma concentrations of free choline and its related metabolites in children and their neurodevelopment in the Seychelles Child Development Nutrition Study, an ongoing longitudinal study assessing the development of children born to mothers with high fish consumption during pregnancy. Plasma concentrations of free choline, betaine, dimethylglycine (DMG), methionine and homocysteine and specific measures of neurodevelopment were measured in 210 children aged 5 years. The children’s plasma free choline concentration (9·17 (sd 2·09) µmol/l) was moderately, but significantly, correlated with betaine (r 0·24; P=0·0006), DMG (r 0·15; P=0·03), methionine (r 0·24; P=0·0005) and homocysteine (r 0·19; P=0·006) concentrations. Adjusted multiple linear regression revealed that betaine concentrations were positively associated with Preschool Language Scale – total language scores (β = 0·066; P=0·04), but no other associations were evident. We found no indication that free choline concentration or its metabolites, within the normal physiological range, are associated with neurodevelopmental outcomes in children at 5 years of age. As there is considerable animal evidence suggesting that choline status during development is associated with cognitive outcome, the issue deserves further study in other cohorts. PMID:23298754

    The goal of this statement was to review the available literature on surveillance, screening, evaluation, and management strategies and put forward a scientific statement that would comprehensively review the literature and create recommendations to optimize neurodevelopmental outcome in the pediatric congenital heart disease (CHD) population. A writing group appointed by the American Heart Association and American Academy of Pediatrics reviewed the available literature addressing developmental disorder and disability and developmental delay in the CHD population, with specific attention given to surveillance, screening, evaluation, and management strategies. MEDLINE and Google Scholar database searches from 1966 to 2011 were performed for English-language articles cross-referencing CHD with pertinent search terms. The reference lists of identified articles were also searched. The American College of Cardiology/American Heart Association classification of recommendations and levels of evidence for practice guidelines were used. A management algorithm was devised that stratified children with CHD on the basis of established risk factors. For those deemed to be at high risk for developmental disorder or disabilities or for developmental delay, formal, periodic developmental and medical evaluations are recommended. A CHD algorithm for surveillance, screening, evaluation, reevaluation, and management of developmental disorder or disability has been constructed to serve as a supplement to the 2006 American Academy of Pediatrics statement on developmental surveillance and screening. The proposed algorithm is designed to be carried out within the context of the medical home. This scientific statement is meant for medical providers within the medical home who care for patients with CHD. Children with CHD are at increased risk of developmental disorder or disabilities or developmental delay. Periodic developmental surveillance, screening, evaluation, and reevaluation

    The authors report the natural history of closure of the cavum Septi pellucidi in premature infants 26 to 27 weeks postconception at birth and compare the developmental outcome in these infants who had closure by 42 weeks postconception to those who still had a cavum septum pellucidi visualized on ultrasound at approximately term (35-42 weeks). Of 72 patients, 35 patients still had a cavum septum pellucidi visualized on the last ultrasound done between 35 and 42 weeks postconception, and the developmental outcome of these patients was no different from those with earlier closure. The authors conclude that persistence of a cavum septi pellucidi through term is not an independent risk factor for developmental delay.

    Background Prenatal alcohol exposure (PAE) is an established risk factor for neurodevelopmental deficits in the offspring. Prenatal depression has been associated with neurodevelopmental deficits in the offspring, although investigations into un-medicated prenatal depression have been inconsistent. We hypothesized that un-medicated prenatal depressive symptoms would independently and jointly with PAE predict neurodevelopmental outcomes in infant offspring. Methods We studied 344 participants from a randomized clinical trial of multivitamin supplements in pregnant women in Ukraine. Women were recruited based upon peri-conceptional alcohol use and followed up to 12 months postpartum. Prenatal depressive symptoms were assessed at approximately 32 weeks of gestation using the Beck Depression Scale. Neurodevelopment was assessed with the Bayley Scales for Infant Development II Mental Development Index (MDI) and Psychomotor Development Index (PDI) at 6 and 12 months postpartum. Generalized linear regression models were constructed to assess the independent and joint effects of prenatal depressive symptoms and PAE in models adjusted for sociodemographic and pregnancy characteristics. Results PAE was independently associated with deficits in neurodevelopmental outcomes at 6 and 12 months, however, level of prenatal depressive symptoms was not. We found marginal evidence of synergism of depressive symptoms and PAE, with larger deficits in those with both exposures observed for the PDI-6 months (p=0.05) and MDI-12 months (p=0.09). Additionally, there was a suggestion of sexual dimorphism; females had stronger deficits from joint exposures than males (depressive symptom (MDI-6 months) female: −8.28, 95% CI −13.06, −3.49; male: 0.68, 95% CI −4.58, 5.94; p for interaction 0.04). While not statistically significant for the MDI or PDI at 12 months, the trend persisted. Conclusion Infants exposed to PAE and prenatal depression may be at an increased risk of

    Allocation of resources for services and supports for children with neurodevelopmental disorders/disabilities (NDD/D) is often based on the presence of specific health conditions. This study investigated the relative roles of a child's diagnosed health condition and neurodevelopmental and related functional characteristics in explaining child and family health and well-being. The data on children with NDD/D (ages 5 to 14; weighted n = 120,700) are from the 2006 Participation and Activity Limitation Survey (PALS), a population-based Canadian survey of parents of children with functional limitations/disabilities. Direct and indirect effects of child diagnosis status-autism spectrum disorder (ASD)/not ASD-and functional characteristics (particularly, ASD-related impairments in speech, cognition, and emotion and behaviour) on child participation and family health and well-being were investigated in a series of structural equation models, while controlling for covariates. All models adequately fitted the data. Child ASD diagnosis was significantly associated with child participation and family health and well-being. When ASD-related child functional characteristics were added to the model, all direct effects from child diagnosis on child and family outcomes disappeared; the effect of child diagnosis on child and family outcomes was fully mediated via ASD-related child functional characteristics. Children's neurodevelopmental functional characteristics are integral to understanding the child and family health-related impact of neurodevelopmental disorders such as ASD. These findings have implications for the relative weighting given to functional versus diagnosis-specific factors in considering needs for services and supports.

    Premature infants exhibit neurodevelopmental delay and reduced growth of the cerebral cortex. However, the underlying mechanisms have remained elusive. Therefore, we hypothesized that neurogenesis in the ventricular and subventricular zones of the cerebral cortex would continue in the third trimester of pregnancy and that preterm birth would suppress neurogenesis. To test our hypotheses, we evaluated autopsy materials from human fetuses and preterm infants of 16-35 gestational weeks (gw). We noted that both cycling and noncycling Sox2(+) radial glial cells and Tbr2(+) intermediate progenitors were abundant in human preterm infants until 28 gw. However, their densities consistently decreased from 16 through 28 gw. To determine the effect of premature birth on neurogenesis, we used a rabbit model and compared preterm [embryonic day 29 (E29), 3 d old] and term (E32, premature infants, preterm birth suppresses neurogenesis, and hypoxia-mimetic agents might restore neurogenesis, enhance cortical growth, and improve neurodevelopmental outcome of premature infants.

    In Germany almost 10 % of children are born before the end of 37th week of gestation. In at least one quarter of these cases, ascending infection of the vagina plays a causative role, particularly during the early weeks of gestation. If, in addition to the decidua, the amniotic membrane, amniotic fluid and the umbilical cord are also affected, infection not only triggers uterine contractions and premature rupture of membranes but also initiates a systemic inflammatory reaction on the part of the fetus, which can increase neonatal morbidity. Numerous studies and meta-analyses have found that antibiotic therapy prolongs pregnancy and reduces neonatal morbidity. No general benefit of antibiotic treatment was found for premature uterine contractions. But it is conceivable that a subgroup of pregnant women would benefit from antibiotic treatment. It is important to identify this subgroup of women and offer them targeted treatment. This overview summarizes the current body of evidence on antibiotic treatment for impending preterm birth and the effect on neonatal outcomes. PMID:24771902

    Preterm deliveries complicate 11% of all births within the United States. In the urban inner city population, this figure approaches approximately 18%. In one quarter to one third of these deliveries, preterm premature rupture of the membranes (PPROM) has been a causative factor. The purpose of this study was to evaluate outcomes of pregnancies complicated by preterm premature rupture of membranes at less than or equal to 24 weeks gestation at our institution. A retrospective review of 300 charts was performed on patients delivered at our institution from December 2003 to December 2004. Patients with gestational ages between 20 and 24 weeks with ruptured membranes were included in the study. Maternal, fetal, placental, and neonatal characteristics were reviewed. A total of 16 infants were delivered. Seven infants were live born. The latency period was 4 days. The mean gestational age was 22 1/7 weeks. The average life span of the live born infants was noted to be 20 days. Chorioamnionitis was demonstrated in 85% of the placental specimens; in 57% of these specimens, group B streptococcus was noted to be the etiologic agent. Of the 16 infants delivered, only one infant is still alive and neurologically intact. Various pathogens have been associated with PPROM and subsequent preterm delivery. The findings of this study suggest that within our population, group B streptococcus appears to be the primary causal agent associated with PPROM. Prevention of infection by early surveillance and patient education may help to decrease the incidence, but further investigation is warranted.

    Extremely low birth weight (ELBW) infants are exposed to many painful procedures while in the neonatal intensive care unit (NICU), such as catheter insertion and endotracheal intubation. Exposure of ELBW infants to repetitive pain and stress in the NICU can lead to cardiovascular instability and may alter neuronal and synaptic organization. Opioid analgesics are administered to reduce pain, stress and to potentially reduce poor neurologic outcomes. They may also be utilized as sedation for mechanically ventilated ELBW infants. There is limited data in regards to neurodevelopmental outcomes of preterm infants exposed to opioids, and available studies have conflicting results. To examine the relationship between cumulative opioid dose in ELBW infants in the NICU and neurodevelopmental outcomes at 20 months corrected age (CA). 100 ELBW infants who had complete neurodevelopmental assessments at 20 months CA were categorized by cumulative opioid exposure during the NICU stay (high vs. low/no opioid). Outcome measures included cognitive, motor and language scores from the Bayley Scales of Infant and Toddler Development-III (BSITD-III). Multiple regression analyses adjusted for the impact of social and neonatal risk factors on outcome. There were 60 patients with high and 40 with low/no opioid exposure. Infants in the high dose group had a higher number of median ventilator days (53.5 vs. 45.6 days, p=0.046) and a higher incidence of necrotizing enterocolitis (5% vs. 21.7%, p=0.022). There were no significant differences in BSITD-III scores between the two opiate groups. In multivariate analysis cumulative opioid dose was associated with lower cognitive scores on the BSITD-III even after adjusting for social and neonatal risk factors (β=-0.247, p=0.012). Cumulative opioid dose is associated with worse cognitive scores at 20 months CA even after adjusting for social and neonatal risk factors. Copyright © 2015 Elsevier Ireland Ltd.

    The primary aim of the study was to determine how the risk of adverse outcomes was related to the duration of the latency period and gestational age at birth following preterm premature rupture of the fetal membranes (PPROM). Retrospective review of infants discharged from 330 neonatal intensive care units. We defined four subgroups based on gestational age: 23 to 25, 26 to 28, 29 to 31 and 32 to 34 weeks. Each gestational age group was evaluated by duration of ROM: 28 days and compared with a referent group (PPROM of >24 h but rupture of membranes (ROM) >24 h. Compared with a reference group (PPROM of >24 h but 28 days was consistently associated with increased mortality and decreased likelihood of survival without morbidity in all gestational age subgroups. PPROM for >28 days is associated with an increased risk of death and morbidity.

    Full Text Available Abstract Background Experimental animal studies and one population-based study have suggested an increased risk for adverse neurodevelopmental outcome after prenatal exposure to SSRIs. We describe the methods and design of a population-based study examining the association between prenatal SSRI exposure and neurodevelopment until age 14. Methods and design This is a cohort study of national registers in Finland: the Medical Birth Register, the Register of Congenital Malformations, the Hospital Discharge Register including inpatient and outpatient data, the Drug Reimbursement Register, and the Population Register. The total study population includes 845,345 women and their live-born, singleton offspring aged 14 or younger and born during Jan 1st 1996-Dec 31st 2010. We will compare the prevalence of psychiatric and neurodevelopmental outcomes in offspring exposed prenatally to SSRIs to offspring exposed to prenatal depression and unexposed to SSRIs. Associations between exposure and outcome are assessed by statistical methods including specific modeling to account for correlated outcomes within families and differences in duration of follow-up between the exposure groups. Descriptive results. Of all pregnant women with pregnancy ending in delivery (n = 859,359, 1.9% used SSRIs. The prevalence of diagnosed depression and depression-related psychiatric disorders within one year before or during pregnancy was 1.7%. The cumulative incidence of registered psychiatric or neurodevelopmental disorders was 6.9% in 2010 among all offspring born during the study period (age range 0–14 years. Discussion The study has the potential for significant public health importance in providing information on prenatal exposure to SSRIs and long-term neurodevelopment.

    Full Text Available Introduction: Different growth and neuro-developmental outcomes have been associated with different doses of thyroxine given to infants with congenital hypothyroidism (CH. Materials and Methods: We studied the longitudinal growth pattern and assessed the neurodevelopment of 45 children with CH(25 girls, 20 boys diagnosed through the national screening program in Qatar, for 6 years or more to examine the effects of initial T4 dosage (50 μg/day with adjustment of T4 dose to maintain serum free T4 concentrations within the upper quartile of normal range and thyroid stimulating hormone < 4 mIU/mLThe birth size of newborns with CH diagnosed through the screening program before January 2003, was recorded and their growth in weight and stature was monitored every 3 months for at least 6 years of life. The IQ of children was assessed between 3 and 6 years of age using The Wechsler Preschool and Primary Scale of Intelligence (WPPSI-III. Results: Birth weight, length, and head circumference of patients (3.21 ± 0.43 kg, 50.5 ± 3.21 cm and 34.1 ± 1.5 cm, respectively did not differ than those for 10,560 normal newborns with normal thyroid function (3.19 ± 0.59 kg, 50.5 ± 2.2 cm and 34.2 ± 1.7 cm. During the first year CH children growth (25.8 ± 2.8 cm/year was similar to those for normal infants (25.5 ± 0.75 cm/year. During the first 6 years, stature growth was normal in all children with CH versus Center for disease control and prevention (CDC data. The mean height standard deviation score (HtSDS of children with CH showed adjustment (± 0.5 SD toward their mid-parental height SDS (MPHtSDS only during the second year of life. The children′s mean HtSDS was higher by an average of 0.4 SD between the 2 nd and 7 th year of life. Conclusion: These data proved that effective screening and treatment completely assures normal neurodevelopment and linear growth in patients with CH. The data showed that their HtSDS slightly exceeds their MPHtSDS during

    To evaluate whether carriers of group B streptococcus (GBS) have adverse obstetric and neonatal outcomes when preterm premature rupture of membranes (PPROM) occurs. In a retrospective study, data were reviewed for women with a singleton pregnancy and PPROM before 34 weeks who attended the Meir Medical Center, Kfar Saba, Israel, between 2005 and 2012. All women received roxithromycin for 1 week, and ampicillin until GBS culture results were available. Ampicillin was continued to 1 week if the GBS culture was positive. The primary study outcome measure was the latency period (time from rupture of membranes to active/induced labor). Among 116 eligible patients, 21 (18.1%) were GBS carriers and 95 (81.9%) noncarriers. The latency period was 11.2 ± 18.1 days for GBS carriers versus 7.5 ± 9.6 days for noncarriers (P=0.93). However, there was a correlation between the length of ampicillin treatment and the latency period (Spearman correlation coefficient 0.7; Poutcomes. GBS carriers with PPROM did not have adverse outcomes. Longer treatment with ampicillin among GBS carriers prolonged the latency period.

    Full Text Available SUMMARY Objective: To determine the association between amniotic fluid index (AFI and perinatal outcomes in preterm premature rupture of membranes (PPROM. Method: A retrospective cohort study was conducted between 2008 and 2012. 86 pregnant women were included, with a diagnosis of PPROM and gestational age from 24 to 35 weeks. Women who presented hypertensive disorders, diabetes, fetuses with birth defects and infection at admission were excluded. To determine the association between AFI and perinatal outcomes, chi-square and Fisher’s exact test were used if necessary, as well as risk ratio (RR and 95% confidence intervals (95CI. Correlation between AFI and perinatal outcomes was determined by using simple linear regression, and AFI progression during pregnancy was analyzed by Z-test. Results: When comparing newborns presenting ultrasound with AFI5cm, there was a higher frequency of perinatal mortality when the AFI was lower than 5 cm. However, when the oligohydramnios was diagnosed as severe (AFI3cm. There was a positive correlation between AFI and gestational age at delivery, birth weight and Apgar scores at minutes 1 and 5. There was also a decrease in amniotic fluid volume with increased gestational age. Conclusion: The presence of severe oligohydramnios after PPROM contributed to a higher frequency of perinatal complications and death.

    To investigate the effect of pre- and postdischarge interventions on breastfeeding outcomes and weight gain among preterm infants. PubMed and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) database were searched for study selection using MeSH terms infant/premature, breastfeeding, weight gain, patient discharge, postnatal care, and counseling. Inclusion criteria included studies that involved preterm infants who were born less than or equal to 37 weeks of gestation, randomized controlled trials that were in English, conducted in developed countries, and had breastfeeding and weight gain outcomes. A total of 8 articles met inclusion criteria. All data related to breastfeeding outcomes including duration, exclusivity, maternal satisfaction, and weight gain were extracted from the randomized controlled trials for the purpose of data synthesis. A total of 310 studies were reviewed. Eight randomized controlled trials met the inclusion criteria. Gestational age of the infants in the studies ranged from 26 to 37 weeks. The results revealed that kangaroo care, peer counseling, in-home breast milk intake measurement, and postdischarge lactation support improved breastfeeding outcomes among preterm infants, and that maternal satisfaction improved with postdischarge interventions. No significant evidence of pre- and postdischarge interventions on weight gain was found. Pre- and postdischarge interventions were effective in promoting breastfeeding exclusivity, duration, and maternal satisfaction among mothers of preterm infants. These findings have important clinical implications that support the need for evidence-based breastfeeding interventions for preterm infants before discharge and vigilant postdischarge support. Research to determine more effective interventions to promote exclusive and long-term breastfeeding among preterm infants is required.

    To study the pathogen distribution and risk factors of nosocomial infection in very preterm infants, as well as the risk of adverse outcomes. A retrospective analysis was performed for the clinical data of 111 very preterm infants who were born between January and December, 2016 and had a gestational age of nosocomial infection after 72 hours of hospitalization, the infants were divided into infection group and non-infection group. The infection group was analyzed in terms of pathogenic bacteria which caused infection and their drug sensitivity. A multivariate logistic regression analysis was used to investigate the potential risk factors and risk of adverse outcomes of nosocomial infection in very preterm infants. Gram-negative bacteria were the main pathogens for nosocomial infection in very preterm infants and accounted for 54%, among which Pseudomonas aeruginosa was the most common one; the following pathogens were fungi (41%), among which Candida albicans was the most common one. The drug sensitivity test showed that Gram-negative bacteria were highly resistant to β-lactam and carbapenems and highly sensitive to quinolones, while fungi had low sensitivity to itraconazole and high sensitivity to 5-fluorocytosine and amphotericin B. Early-onset sepsis, duration of peripherally inserted central catheter, steroid exposure, and duration of parenteral nutrition were risk factors for nosocomial infection in very preterm infants (Pinfection group, the infection group had significantly higher risks of pulmonary complications (PNosocomial infection in very preterm infants is affected by various factors and may increase the risk of adverse outcomes. In clinical practice, reasonable preventive and treatment measures should be taken with reference to drug sensitivity, in order to improve the prognosis of very premature infants.

    To compare the neurodevelopmental outcomes between preterm infants with diffuse excessive high signal intensity (DEHSI) and those without DEHSI on magnetic resonance (MR) images, in association with other white matter lesions. This retrospective study was approved by the institutional review board, and requirement to obtain informed consent was waived. High-risk preterm infants (n = 126) who underwent screening brain MR imaging at near-term-equivalent age were classified into two groups according to the presence of DEHSI. Bayley Scales of Infant Development-II, presence of cerebral palsy, and neurosensory impairment between 18 and 24 months of age were compared between the two groups. The associations of MR findings of other white matter lesions (cystic encephalomalacia, punctate lesions, loss of volume, ventricular dilatation, and delayed myelination) and subsequent outcomes were also analyzed. Outcome data were evaluated by using exact logistic regression analyses and Fisher exact test. DEHSI was present in 75% (95 of 126) of infants. Subsequent neurodevelopmental outcomes did not differ significantly between the two groups. Severe motor delay and cerebral palsy were more common in infants with both DEHSI and other white matter lesions as compared with infants with normal white matter (P = .001 and P cystic encephalomalacia (odds ratio, 19.6; 95% confidence interval: 1.3, 333.3) and punctate lesions (odds ratio, 90.9; 95% confidence interval: 6.4, 1000) were significant predictors of cerebral palsy. Although the incidence of DEHSI was high (75%) in preterm infants at near-term-equivalent age MR imaging, DEHSI was not predictive of following adverse outcomes. Cystic encephalomalacia and punctate lesions were more significant predictors of cerebral palsy.

    Preclinical data suggest that general anaesthetics affect brain development. There is mixed evidence from cohort studies that young children exposed to anaesthesia can have an increased risk of poor neurodevelopmental outcome. We aimed to establish whether general anaesthesia in infancy has any effect on neurodevelopmental outcome. Here we report the secondary outcome of neurodevelopmental outcome at 2 years of age in the General Anaesthesia compared to Spinal anaesthesia (GAS) trial. In this international assessor-masked randomised controlled equivalence trial, we recruited infants younger than 60 weeks postmenstrual age, born at greater than 26 weeks' gestation, and who had inguinal herniorrhaphy, from 28 hospitals in Australia, Italy, the USA, the UK, Canada, the Netherlands, and New Zealand. Infants were randomly assigned (1:1) to receive either awake-regional anaesthesia or sevoflurane-based general anaesthesia. Web-based randomisation was done in blocks of two or four and stratified by site and gestational age at birth. Infants were excluded if they had existing risk factors for neurological injury. The primary outcome of the trial will be the Wechsler Preschool and Primary Scale of Intelligence Third Edition (WPPSI-III) Full Scale Intelligence Quotient score at age 5 years. The secondary outcome, reported here, is the composite cognitive score of the Bayley Scales of Infant and Toddler Development III, assessed at 2 years. The analysis was as per protocol adjusted for gestational age at birth. A difference in means of five points (1/3 SD) was predefined as the clinical equivalence margin. This trial is registered with ANZCTR, number ACTRN12606000441516 and ClinicalTrials.gov, number NCT00756600. Between Feb 9, 2007, and Jan 31, 2013, 363 infants were randomly assigned to receive awake-regional anaesthesia and 359 to general anaesthesia. Outcome data were available for 238 children in the awake-regional group and 294 in the general anaesthesia group. In the

    We present a retrospective review of 228 pre-term premature rupture of membranes (PPROM) singleton pregnancies followed-up in our clinic between 1996 and 2005. The most common neonatal morbidities in PPROM cases are respiratory distress syndrome (RDS), sepsis and intraventricular haemorrhage (IVH). The route of delivery does not affect newborn intensive care unit (NICU) requirements, perinatal asphyxia, sepsis and IVH rates in PPROM cases. NICU and PPV requirements, RDS, sepsis and IVH rates increase if the Apgar score is < 5. Neonatal morbidity and mortality rates increase as the latent period lengthens. C reactive protein (CRP) on admission, last CRP, birth weight and the 5 min Apgar score was found to be associated with NICU requirements; only the 5 min Apgar score was found to be associated with RDS; and last leukocyte count and maternal haemotocrit was found to be associated with sepsis and pneumonia, independently. In PPROM cases, CRP on admission, last CRP, birth weight, the 5 min Apgar score, last leukocyte count and maternal haemotocrit, should be considered to predict neonatal outcomes.

    Observational studies have shown an association between transiently low thyroid hormone levels in preterm infants in the first weeks of life (transient hypothyroxemia) and an abnormal neurodevelopmental outcome. Thyroid hormone therapy might prevent this morbidity. To assess whether thyroid hormone therapy in preterm infants without congenital hypothyroidism results in clinically important changes in neonatal and long term outcomes in terms of both benefits and harms. The standard search strategy of the Neonatal Review Group was used. This included searches of the Oxford Database of Perinatal Trials, Cochrane Controlled Trials Register, MEDLINE, previous reviews including cross references, abstracts, conferences, symposia proceedings, expert informants and journal handsearching in the English language. All trials using random or quasi-random patient allocation, in which thyroid hormone therapy (either treatment or prophylaxis) was compared to a control in premature infants. Primary clinical outcomes included measures of neurodevelopmental outcome and mortality. Assessment of trial quality, data extraction and synthesis of data, using relative risk (RR) and weighted mean difference (WMD), were performed using standard methods of the Cochrane Collaboration and its Neonatal Review Group. Eight studies were identified that compared thyroid hormone treatment to control. Four randomized or quasi-randomized studies met inclusion criteria (Chowdhry 1984, Amato 1989, van Wassenaer 1997 and Vanhole 1997). All studies enrolled preterm infants thyroid hormones. Three studies used thyroxine, whereas Amato 1989 used triiodothyronine. Only two studies with neurodevelopmental follow-up were of good methodology (van Wassenaer 1997 and Vanhole 1997). All studies were of small size with the largest, van Wassenaer 1997, enrolling 200 infants. A lack of comparability of data (neurodevelopmental test or timing of follow-up) prevented meta-analytic pooling of the studies for

    Full Text Available Objectives: Preterm premature rupture of membranes (PPROM is defined as a rupture of the amniotic membranes occurring before 37 weeks of gestation and before the onset of labor. Extreme PPROM occurs prior to 26 weeks gestation and contributes to an increased risk of prematurity, leading to maternal and fetal complications. This study aims to estimate the risk factors associated with various maternal complications and to determine the worst outcomes in Omani females with extreme PPROM.Methods: A retrospective cohort study was conducted on 44 women with extreme PPROM, who delivered at Sultan Qaboos University Hospital (SQUH from January 2006 to December 2011. Women with incomplete information, multiple gestations, or a preterm delivery resulting from medical intervention, as well as women who delivered elsewhere were excluded from the study.Results: Forty-four women with extreme PPROM were included in our study. The results revealed the most important risk factor to be history of infection, which was noted in 24 study participants. The mean maternal age was 30 years. The mean gestational age at PPROM and at delivery were 20.7±3.2 (range: 16-26 weeks and 29.7±7.6 weeks (range: 17-40 weeks, respectively. The maternal complications observed in this study included; infection which was seen in 20 (45% patients, antepartum hemorrhage in 11 (25% patients, and cesarean section which was required in 12 (27% patients. There was no significant association between risk factors such as gestational age at delivery, parity, maternal age at PPROM, or maternal Body Mass Index (BMI and cesarean section rate. Infection played a major role, both as a risk factor and in causing extreme PPROM, which in turn increased in 12 patients (27%. In the multivariable model for predicting the need for cesarean section (gestational age at delivery, parity, maternal age at PPROM in years and maternal BMI, none of the factors were statistically significant.Conclusion: Overall

    To report the outcomes of cataract surgery in children with retinopathy of prematurity (ROP). A retrospective case review of all children diagnosed with ROP from January 2001 to December 2014 was done and those who underwent cataract surgery were included in the study. Details of ROP and cataract treatment, postoperative complications and outcomes were analysed. Of the 2258 children diagnosed to have ROP, 28 eyes of 22 children were included, 14 boys and 8 girls. Mean age at cataract surgery was 18.9 months (range 2 months to 12 years). Most common grade of ROP was stage 4 (13 eyes). Nineteen eyes underwent retinal surgery, scleral buckle (one eye) and laser (three eyes). Five eyes showed spontaneous regression. Mean duration for the development of cataract postretinal surgery was 7.76 months (range 2-32 months). Nine eyes did not receive a primary intraocular lens (IOL). Intraoperative posterior capsular rupture occurred in two eyes. Postoperative complications included visual axis opacification (four), secondary glaucoma (two) and IOL capture (one). Postoperative visual acuity assessment was possible in 23 eyes, 11 had better than 20/200 vision. Eleven patients had a follow-up of at least 2 years and the mean myopic shift at 2 years was -3.07 D in pseudophakes and -8.75 D in aphakes. Cataracts may develop in children with ROP regardless of the modality of intervention. Postoperative complications and refractive changes are similar to those in eyes without ROP.

    Spontaneous resumption of ovarian function is not a rare phenomenon in patients with premature ovarian insufficiency (POI). The outcome of this resumption is not known. To describe the outcome following the resumption of ovarian function in POI patients. Cross-sectional study. University medical centre. Cumulative incidence of ovarian function resumption and risk factors arresting this resumption during follow-up were determined in a large cohort of POI women. Five hundred and seven patients were included in the study, with a follow-up of 3·44 ± 4·05 years (0-29). Of these, 117 (23%) had features of ovarian function resumption. The cumulative incidence of pregnancy was 3·5% among the whole cohort and 15·3% among patients with resumption of ovarian function. Fifty-five patients (47%) experienced an arrest of their resumption during the follow-up period. In univariate analysis, high FSH and DHEA levels at initial evaluation were risk factors for the arrest of the resumption of ovarian function. In multivariate analysis, high FSH levels at the initial evaluation [1·89 (1·10-3·23), P = 0·03] and older age at diagnosis [1·53 (1·01-2·33), P = 0·04] were risk factors for the arrest of this resumption. Resumption of ovarian function is not a rare or brief phenomenon in POI women. The identification of predictive factors of this resumption, as well as its duration, increases our knowledge of the natural history of POI, and will improve the medical management, especially infertility counselling of these patients. © 2016 John Wiley & Sons Ltd.

    Seafood intake in pregnancy has been positively associated with childhood cognitive outcomes which could potentially relate to the high vitamin D content of oily fish. However, whether higher maternal vitamin D status (serum 25-hydroxyvitamin D (25(OH)D)) in pregnancy is associated with a reduced risk of offspring suboptimal neurodevelopmental outcomes is unclear. A total of 7065 mother-child pairs were studied from the Avon Longitudinal Study of Parents and Children cohort who had data for both serum total 25(OH)D concentration in pregnancy and at least one measure of offspring neurodevelopment (pre-school development at 6-42 months; 'Strengths and Difficulties Questionnaire' scores at 7 years; intelligence quotient (IQ) at 8 years; reading ability at 9 years). After adjustment for confounders, children of vitamin D-deficient mothers (<50·0 nmol/l) were more likely to have scores in the lowest quartile for gross-motor development at 30 months (OR 1·20; 95 % CI 1·03, 1·40), fine-motor development at 30 months (OR 1·23; 95 % CI 1·05, 1·44) and social development at 42 months (OR 1·20; 95 % CI 1·01, 1·41) than vitamin D-sufficient mothers (≥50·0 nmol/l). No associations were found with neurodevelopmental outcomes, including IQ, measured at older ages. However, our results suggest that deficient maternal vitamin D status in pregnancy may have adverse effects on some measures of motor and social development in children under 4 years. Prevention of vitamin D deficiency may be important for preventing suboptimal development in the first 4 years of life.

    Premature ejaculation (PE) is quite common. Although effective treatments do exist, only a few affected people consult a practitioner in order to overcome their problem. At the same time, studies have shown that reading didactical documents about their PE problem (bibliotherapy) can be useful to men. The aim of this study was to improve the bibliotherapy approach using up-to-date knowledge and techniques. The expected benefits were the following: (i) an effective manual shorter than previous ones; (ii) easier to assimilate therapeutic principles; and (iii) a method thereby made accessible to a broad population most of whom usually do not consult for this type of sexual problem. A short bibliotherapy titled The Practical Guide of PE[in French] was tested among PE subjects who were diagnosed with PE according to Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision criteria. Assessments were made at baseline (N = 421), at 4-8 months (N = 120), and at 10-14 months (N = 79) after they read The Practical Guide. A control group of 66 subjects was left on a waiting list and was assessed 2 months after baseline. The main outcome measures are self-reported ejaculatory latency time, feeling of control upon ejaculation, sexual satisfaction, distress related to PE, anxiety experienced during sexual intercourse, and sexual cognitions (Sexual Irrationality Questionnaire). Significant improvements were found for all the self-reported parameters, both at 4-8 and at 10-14 months after the bibliotherapy. The improvements were associated with an adjustment of sexual cognitions. The response to treatment seemed better for those subjects with moderate PE. Although the severity criteria used in this study did not precisely meet the International Society for Sexual Medicine criteria for lifelong PE, they were likely related. The response did not seem to be affected by variables such as age, education, or personality. Its cost/benefit ratio makes The

    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. Copyright © 2013 John Wiley & Sons, Ltd.

    Dental amalgam is approximately 50% metallic mercury and releases mercury vapor into the oral cavity, where it is inhaled and absorbed. Maternal amalgams expose the developing fetus to mercury vapor. Mercury vapor can be toxic, but uncertainty remains whether prenatal amalgam exposure is associated with neurodevelopmental consequences in offspring. To determine if prenatal mercury vapor exposure from maternal dental amalgam is associated with adverse effects to cognition and development in children. We prospectively determined dental amalgam status in a cohort of 300 pregnant women recruited in 2001 in the Republic of Seychelles to study the risks and benefits of fish consumption. The primary exposure measure was maternal amalgam surfaces present during gestation. Maternal occlusal points were a secondary measure. Outcomes were the child's mental (MDI) and psychomotor (PDI) developmental indices of the Bayley Scales of Infant Development-II (BSID-II) administered at 9 and 30 months. Complete exposure, outcome, and covariate data were available on a subset of 242 mother-child pairs. The number of amalgam surfaces was not significantly (p>0.05) associated with either PDI or MDI scores. Similarly, secondary analysis with occlusal points showed no effect on the PDI or MDI scores for boys and girls combined. However, secondary analysis of the 9-month MDI was suggestive of an adverse association present only in girls. We found no evidence of an association between our primary exposure metric, amalgam surfaces, and neurodevelopmental endpoints. Secondary analyses using occlusal points supported these findings, but suggested the possibility of an adverse association with the MDI for girls at 9 months. Given the continued widespread use of dental amalgam, we believe additional prospective studies to clarify this issue are a priority. Copyright © 2012 Elsevier Inc. All rights reserved.

    Monomethylmercury (MeHg(+)) is an environmental pollutant, which at sufficiently high exposures, has induced neurotoxicosis in several animal species, including humans. Adverse neurological effects due to gestational exposure are of particular concern as MeHg(+) readily crosses the blood-brain and placental barriers. The degree to which environmental concentrations in marine prey affect free-living piscivorous wildlife, however, remains largely undetermined. We examined associations of gestational exposures to mercury on neurodevelopment and survival using hair and blood concentrations of total mercury ([THg]) in a stranded population of Pacific harbor seal pups from central California. A positive association was determined for the presence of abnormal neurological symptoms and increasing [THg] in blood (P = 0.04), but not hair. Neither hair nor blood [THg] was significantly associated with survival, or the neurodevelopmental milestone 'free-feeding', which was measured from the onset of hand-assisted feeding to the time at which pups were able to consume fish independently. Both hair and blood [THg] exceeded threshold values considered potentially toxic to humans and other mammalian wildlife species. The higher [THg] in blood associated with abnormal neurological symptoms may indicate an adverse effect of this pollutant on neurodevelopment in harbor seal pups. These data have broader implications with respect to human health and public policy as harbor seals and humans consume similar fish species, and it is possible that safeguard levels established for marine mammals could also extend to human populations that regularly consume fish.

    The prediction of long-term outcomes in surviving infants born very preterm (VPT) or with very low birth weight (VLBW) is necessary to guide clinical management, provide information to parents, and help target and evaluate interventions. There is a large body of literature describing risk factor models for neurodevelopmental outcomes in VPT/VLBW children, yet few, if any, have been developed for use in routine clinical practice or adopted for use in research studies or policy evaluation. We sought to systematically review the methods and reporting of studies that have developed a multivariable risk factor model for neurodevelopment in surviving VPT/VLBW children. We searched the MEDLINE, Embase, and PsycINFO databases from January 1, 1990, to June 1, 2014, and identified 78 studies reporting 222 risk factor models. Most studies presented risk factor analyses that were not intended to be used for prediction, confirming that there is a dearth of specifically designed prognostic modeling studies for long-term outcomes in surviving VPT/VLBW children. We highlight the strengths and weaknesses of the research methodology and reporting to date, and provide recommendations for the design and analysis of future studies seeking to analyze risk prediction or develop prognostic models for VPT/VLBW children. © The Author 2017.

    Full Text Available Objectives: Preterm premature rupture of membranes (PPROM is among the most important causes of perinatal morbidity and mortality. The aim of this study is to survey the pregnancy outcomes in preterm premature rupture of membranes with an amniotic fluid index of 5.Methods: This prospective cohort study was performed on 137 pregnant women complicated by preterm premature rupture of membranes (PPROM with a gestational age of 28-34 weeks during October 2006 to October 2008. The patients were divided in two groups according to their amniotic fluid index; AFI<5 (77cases, AFI≥5 (60cases. The Chi-squared test for qualitative variables and T-student test for quantitative variables were used to analyze the results.Results: The results showed that there was no significant difference in terms of the number of pregnancies, gestational age at rupture of membranes and birthweight between the two groups. However, the results demonstrated that the patients with AFI<5 exhibited a significantly shorter latency period (p=0.049, a higher rate of cesarean due to fetal distress (p=0.008, a lower neonatal Apgar score in the first minute (p=0.0127 and a higher rate of neonatal death during the first week (p=0.045.Conclusion: Overall, PPROM with oligohydroamnios is associated with shorter latency, higher rate of C/S, higher rate of early neonatal death and lower neonatal Apgar.

    The risk of intraventricular hemorrhage and periventricular leukomalacia correlates with fetal brain immaturity. Given that the appearance of fetal heart rate (FHR) accelerations is associated with brain maturation, we tested the hypothesis that neonatal cerebral lesions and developmental delay in very low birthweight newborns are associated with absent reactivity of the FHR tracing prior to delivery. We analyzed the FHR tracing of 97 fetuses with birthweight < 1200 g who underwent head ultrasound at day 3 and Bayley Scales of Infant Development testing at age 1 year. We used multivariate analysis to adjust for confounding variables. We found that the absence of two FHR accelerations of 10 beats per minute (bpm) for 10 seconds twice in a 20-minute window 1 hour before delivery was associated with intraventricular hemorrhage and/or periventricular leukomalacia ( P < 0.01) and a significant risk for mental and psychomotor delays by Bayley testing ( P < 0.001). The absence of accelerations of 15 bpm for 15 seconds was not associated with these abnormalities. The absence of FHR accelerations before delivery suggests a greater risk for cerebral injury and developmental delay in the very premature neonate.

The intervention included a screening protocol with a questionnaire and physical tests for musculoskeletal complaints or injuries and functional limitations and, where needed, treatment, early rehabilitation and individually-adjusted physical training. The intervention also included organisation-based training in ergonomics and exercise physiology for officers plus enhanced teamwork between officers and physiotherapist. Not all the soldiers underwent the intervention as planned. The discharge rate was lower in all three units after either of the intervention programmes comparing premature discharge figures with before-implementation study figures. However, significantly fewer soldiers were discharged from the group who underwent the intervention as planned 6.1% compared to the group with the less intensive intervention, 13.1% (p=0.002). The results indicate that the comprehensive intervention programme can reduce the number of premature discharges from the Swedish Armed Forces. The differences between the groups indicate that the effectiveness was greater when the intervention was fully implemented with regard to intensity.

    Full Text Available Vitamin D has an important role in early life; however, the optimal vitamin D status during pregnancy is currently unclear. There have been recent calls for pregnant women to maintain circulating 25-hydroxyvitamin D (25(OHD concentrations >100 nmol/L for health, yet little is known about the long-term potential benefits or safety of achieving such high maternal 25(OHD concentrations for infant or child health outcomes. We examined maternal vitamin D status and its associations with infant anthropometric and later childhood neurocognitive outcomes in a mother-child cohort in a sun-rich country near the equator (4.6° S. This study was conducted in pregnant mothers originally recruited to the Seychelles Child Development Nutrition Study. Blood samples (n = 202 taken at delivery were analysed for serum 25-hydroxyvitamin D (25(OHD concentrations. Multiple linear regression models assessed associations between maternal 25(OHD and birth weight, infant head circumference, and neurocognitive outcomes in the children at age 5 years. Mothers were, on average, 27 years of age, and the children’s average gestational age was 39 weeks. None of the women reported any intake of vitamin D supplements. Maternal 25(OHD concentrations had a mean of 101 (range 34–218 nmol/L and none were deficient (<30 nmol/L. Maternal 25(OHD concentrations were not associated with child anthropometric or neurodevelopmental outcomes. These findings appear to indicate that a higher vitamin D status is not a limiting factor for neonatal growth or neurocognitive development in the first 5 years of life. Larger studies with greater variability in vitamin D status are needed to further explore optimal cut-offs or non-linear associations (including for maternal health that might exist among populations with sub-optimal exposure.

    Progress has been made in tackling malaria however there are still over 207 million cases worldwide, the majority in children. As survival rates improve, numbers of children with long-term neurodisabling sequelae are likely to increase. Most outcome studies in cerebral malaria (CM) have focused only on body function and structure and less on outcomes within the broader framework of the International Classification of Functioning and Disability (ICF). The aim of this study was to utilise qualitative methods to identify relevant clinical outcomes in CM to support formulation of a core outcome set relevant to CM and other acquired brain injuries for use in future clinical trials. In depth interviews with parent/caregivers (CGs) of children with/without previous CM (N = 19), and in depth interviews with health professionals (N = 18) involved in their care were conducted in community and clinical settings in and around Blantyre, Malawi. Interviews were audio taped, transcribed, translated and a thematic content analysis was conducted. Themes were categorised and placed firstly in an iterative framework derived from the data but then within the ICF framework. Outcomes perceived as important to carers and professionals fulfilled each level of the ICF. These included impairment in body function and structure (contractures, impaired mobility, visual problems, seizures, cognitive function and feeding); activity and participation outcomes (learning, self-care, relationships in school, play and activities of daily living). Other issues emerging included the social and emotional implications of CM on the family, and balancing care of children with neurodisability with demands of daily life, financial pressures, and child protection. Themes of stigma and discrimination were described; these were perceived to negatively influence care, participation and integration of carer and child into the community. Outcomes considered important for parents/caregivers and

    The incidence of acute kidney injury (AKI) among the neonates treated at the Neonatal Intensive Care Unit is high with high mortality rates. Glutathione S-transferase (GST) class Pi plays an important role in the protection of cells from cytotoxic and oncogenic agents. The aim of the study was to examine whether the levels of serum glutathione S-transferase Pi (GST Pi) determined after birth have any predictive value for the outcome and development of AKI in premature neonates. The prospective study included 36 premature neonates. The data about morbidity was gathered for all the neonates included in the study. The blood samples were taken in the first 6 h of life and GST Pi levels were measured. The mean values and standard deviations of GST Pi among the neonates who died and who survived were 1.904 ± 0.4535 vs 1.434 ± 0.444 ng/ml (p = 0.0128). Logistic regression revealed a statistically significant, positive correlation between GST Pi levels and death (p = 0.0180, OR7.5954; CI 1.4148-40.7748).The mean value of GST Pi levels in the neonates with AKI was higher than in neonates without AKI (p = 0.011). The conclusion of our study is that high levels of serum GST Pi in the first 6 h after birth are associated with an increased mortality and development of AKI in prematurely born neonates.

    Fetal supraventricular tachycardia (SVT), characterized by a fetal ventricular heart rate faster than 200 beats per minute (bpm), is often diagnosed during routine fetal heart monitoring or prenatal ultrasound examinations. Clinical guidelines for management of fetal SVT have not been determined in standardized trials, nor do we have a clear sense regarding the long-term developmental outcomes and side effects of in utero antiarrhythmic therapy. We describe our approach to the treatment of refractory SVT in a fetus with hydrops using direct umbilical vein treatment with amiodarone coupled with effusion evacuation. We successfully achieved in utero resolution of SVT. There was transient amiodarone-induced hypothyroidism, which we screened for early and treated with Synthroid. Ultimately our patient had normal long-term growth and development as measured by modified Denver office checklists and Ages and Stages questionnaires. Our experience advocates for vigilant screening and management of hypothyroidism in fetuses exposed to in utero amiodarone and suggests that it is possible to achieve good outcomes in high-acuity refractory cases of SVT.

    Background Awake regional anesthesia (RA) is a viable alternative to general anesthesia (GA) for infants undergoing lower abdominal surgery. Benefits include lower incidence of postoperative apnea and avoidance of anesthetic agents that may increase neuroapoptosis and worsen neurocognitive outcomes. The General Anesthesia compared to Spinal anesthesia (GAS) study compares neurodevelopmental outcomes following awake RA or GA in otherwise healthy infants. Our aim was to describe success and failure rates of RA in this study and report factors associated with failure. Methods This was a nested cohort study within a prospective randomized, controlled, observer blind, equivalence trial. Seven hundred twenty two infants ≤ 60 weeks postmenstrual age, scheduled for herniorrhaphy under anesthesia were randomly assigned to receive RA (spinal, caudal epidural or combined spinal caudal anesthetic) or GA with sevoflurane. The data of 339 infants, where spinal or combined spinal caudal anesthetic was attempted, was analyzed. Possible predictors of failure were assessed including: patient factors, technique, experience of site and anesthetist and type of local anesthetic. Results RA was sufficient for the completion of surgery in 83.2% of patients. Spinal anesthesia was successful in 86.9% of cases and combined spinal caudal anesthetic in 76.1%. Thirty four patients required conversion to GA and an additional 23 (6.8%) required brief sedation. Bloody tap on the first attempt at lumbar puncture was the only risk factor significantly associated with block failure (OR = 2.46). Conclusions The failure rate of spinal anesthesia was low. Variability in application of combined spinal caudal anesthetic limited attempts to compare the success of this technique to spinal alone. PMID:26001028

    Donor breastmilk (DBM) has gained popularity as an alternative to formula when mother's own milk (MOM) is unavailable. The objective of this study was to evaluate the effects of a predominantly DBM diet on growth and subsequent neurodevelopment in preterm infants at a level 3 neonatal intensive care unit (NICU). This single-center, observational cohort study compared data from preterm infants supplemented with predominantly (>50%) DBM to those from age- and weight-matched infants fed only MOM or supplemented with predominantly (>50%) preterm formula (PF). The primary outcome was in-hospital weight gain, and the secondary outcome was neurodevelopment, as assessed by the Bayley III scale at 1 and 2 years' corrected age. Exclusion criteria were major congenital defects, death prior to discharge from the NICU, or supplementation volumes of <50% over the first month of life. We compared the outcomes among the 3 feeding groups with the χ 2 test, ANOVA, and ANCOVA, with post hoc pairwise comparisons after adjustment for the following confounders: bronchopulmonary dysplasia, multiple births, and social work involvement. In the entire cohort, the mean gestational age was 27.1 weeks and the mean birthweight was 914 g. The DBM (n = 27) and PF (n = 25) groups were similar with regard to socioeconomic characteristics. DBM infants regained birthweight more slowly over the first month of life compared with infants fed MOM (n = 29) or PF (mean [SD], 17.9 [5.7], 22.0 [6.8], and 20.3 [5.7] g/kg/d, respectively; P = 0.05); however, this growth difference was attenuated at later time points. In a fully adjusted model, the DBM group scored significantly lower in cognition at both 1 year (P = 0.005) and 2 years (P = 0.03) of age compared with the infants fed non-DBM diets. The findings from this study suggest that in this NICU, preterm infants supplemented with predominantly DBM had compromised early in-hospital weight gain and, possibly, early cognitive delays compared with infants

    Delayed visual maturation (DVM) can present as an isolated anomaly (type 1A), but can be compounded by perinatal problems (type 1B), severe neurodevelopmental delay (type 2), or ocular anomalies/nystagmus (type 3), in which group the common feature appears to be nystagmus. The neurodevelopmental and ophthalmic aspects of 26 infants with DVM were studied. Onset of visual improvement, rate of acquisition of normal vision and eventual outcome were studied quantitatively, using an adaptation of the acuity card procedure. Neurodevelopmental assessment was performed after visual improvement. The results support the long-held clinical impression that if blindness is the presenting feature, neurodevelopmental outlook is excellent. DVM could represent a defect in the extrageniculostriate visual system, and the onset of vision in all types--and the development of nystagmus in type 3--could herald the emergence of geniculostriate function.

    Full Text Available Introduction: Preterm premature rupture of the membranes (PPROM is one of the most important causes of perinatal morbidity and mortality. The aim of this study was to evaluate pregnancy outcome in preterm premature rupture of the membranes with amniotic fluid index less than 5 and more than 5. Methods: This prospective study was performed on 137 pregnant women with gestational age of 28-34 weeks with PPROM from Oct 2006 to Oct 2008. The patients were divided in two groups according to amniotic fluid index: AFI<5 (77 cases, AFI≥5 (60 cases. Chi-square test was used for qualitative variables, while T-student test was used for quantitative test. Results: Both groups were similar with respect to number of pregnancies, gestational age at rupture of the membranes and birth weight. In the group with AFI<5, applied latency was significantly shorter (PV=0.049, rate of cesarean section was higher due to fetal distress (PV=0.008, neonatal Apgar score in first minute was lower during the first week (PV=0.0127 and the rate of neonatal death was higher (PV=0.045 during the first week. Conclusion: An AFI<5 cm after PPROM is associated with earlier delivery, higher rate of cesarean due to fetal distress, higher rate of neonatal death, and lower neonatal Apgar score in first minute during the first week

    Despite newborn screening and early levothyroxine replacement, there are continued reports of mild neurocognitive impairment in children with congenital hypothyroidism (CHT). In Auckland, New Zealand, cases are identified by a neonatal screening program with rapid institution of high-dose levothyroxine replacement (10-15 μg/kg·d), producing prompt normalization of thyroid function. Subsequently, frequent monitoring and dose alterations are performed for 2 years. We aimed to assess whether the Auckland treatment strategy prevents impairment of intellectual and motor development. This study encompassed all children with CHT born in 1993-2006 in Auckland and their siblings. Neurocognitive assessments included the following: 1) intelligence quotient via Weschler Preschool and Primary Scale of Intelligence III or Weschler Intelligence Scale for Children IV; 2) Movement Assessment Battery for Children; and 3) Beery Developmental Test of Visual-Motor Integration. Body composition was assessed by dual-energy x-ray absorptiometry. Forty-four CHT cases and 53 sibling controls aged 9.6 ± 3.9 years were studied. Overall intelligence quotient was similar among CHT cases and controls (95.2 vs 98.6; P = .20), and there were also no differences in motor function. Severity of CHT did not influence outcome, but greater time to normalize free T4 was associated with worse motor balance. There were no differences in anthropometry or body composition between groups. These findings suggest that a strategy of rapidly identifying and treating infants with CHT using high-dose levothyroxine replacement is associated with normal intellectual and motor development. The subtle negative impact on motor function associated with time to normalize free T4 levels is consistent with benefit from rapid initial correction.

    This study sought to determine whether changes in neurodevelopmental outcomes between 18 and 36 months of age were associated with prenatal exposure to triptan medications, a class of 5-HT receptor agonists used in the treatment of migraine. Using data from the Norwegian Mother and Child Cohort Study, a prospective birth cohort that includes nearly 40% of all pregnancies in Norway from 1999 to 2008, we identified 50 469 mother-child dyads who met inclusion criteria and were present for at least one follow-up assessment at 18 or 36 months postpartum. Neurodevelopment was assessed using the Child Behaviour Checklist, the Emotionality, Activity, and Shyness Questionnaire, and the Ages and Stages Questionnaire. We used generalised estimating equations to evaluate change from 18 to 36 months for children prenatally exposed to triptans, relative to contrast groups, and used marginal structural models with inverse probability of treatment and censoring weights to address time-varying exposure and confounding as well as loss to follow-up. Among eligible participants (n=50 469), 1.0% used a triptan during pregnancy, 2.0% used triptans prior to pregnancy only, 8.0% reported migraine without triptan use and 89.0% had no history of migraine. Children with prenatal triptan exposure had greater increases in emotionality (r-RR 2.18, 95% CI 1.03 to 4.53) and activity problems (r-RR 1.70, 95% CI 1.02 to 2.8) compared to children born to mothers who discontinued triptan use prior to pregnancy. Prenatal triptan exposure was associated with changes over time in externalising-type behaviours such as emotionality and activity, but not with internalising-type behaviours.

    2009-01-01

    Full Text Available Background: While lens-sacrificing vitrectomy is the standard approach to manage Stage 5 retinopathy of prematurity (ROP, scleral buckling has been used to manage some cases of Stage 4. Lens-sparing vitrectomy was popularized by Maguire and Trese in selected cases of Stage 4 disease. Purpose: To assess the functional and visual outcomes after primary lens-sparing pars plana vitrectomy for Stage 4 ROP. Materials and Methods: In a retrospective, interventional, consecutive case series, the records of 39 eyes of 31 patients presenting with Stage 4 retinal detachment secondary to ROP who underwent primary two or three-port lens-sparing vitrectomy from January 2000 to October 2006 were evaluated. The outcomes studied at the final follow-up visit were the retinal status, lens and medial clarity and visual acuity . Favorable anatomical outcome was defined as the retinal reattachment of the posterior pole at two months after the surgery; and favorable functional outcome was defined as a central, steady and maintained fixation, with the child following light. Results: At mean follow-up of 15 months, 74% of the eyes had a favorable anatomical outcome with single procedure. The visual status was favorable in 63% . The lens remained clear in all the eyes at the last follow-up, and the media clarity was maintained in 87%. Intraoperative complications included vitreous hemorrhage, pre-retinal hemorrhage and retinal break formation. Conclusions: Lens-sparing vitrectomy helps to achieve a favorable anatomical and functional outcome in selected cases of Stage 4 ROP.

    Preterm premature rupture of membranes (PPROM) complicates 1% of all pregnancies and occurs in one third of all preterm deliveries. Midtrimester PPROM is often followed by spontaneous miscarriage and elective termination of ongoing pregnancies is offered in many countries. The aim of this retrospective descriptive cohort study was to investigate the natural history of midtrimester PPROM in a jurisdiction where termination of pregnancy in the absence of maternal compromise is unavailable. Cases of midtrimester PPROM diagnosed between 14 and 23 + 6 weeks' gestation during April 2007 to June 2012 were identified following a manual search of all birth registers, pregnancy loss registers, annual reports, ultrasound reports, emergency room registers and neonatal death certificates at Cork University Maternity Hospital - a large (circa 8500 births per annum) tertiary referral maternity hospital in southwest Ireland. Cases where delivery occurred within 24 h of PPROM were excluded. The prevalence of midtrimester PPROM was 0.1% (42 cases/44,667 births). The mean gestation at PPROM was 18 weeks. The mean gestation at delivery was 20 + 5 weeks, with an average latency period of 13 days. Ten infants were born alive (23%; 10/42). The remainder (77%; 32/42) died in utero or intrapartum. Nine infants were resuscitated. Two infants survived to discharge. The overall mortality rate was 95% (40/42). Five women had clinical chorioamnionitis (12%; 5/42) but 69% demonstrated histological chorioamnionitis. One woman developed sepsis (2.4%; 1/42). Other maternal complications included requirement of intravenous antibiotic treatment (38%; 17/42), retained placenta (21%, 9/42) and post-partum haemorrhage (12%; 5/42). This study provides useful and contemporary data on midtrimester PPROM. Whilst fetal and neonatal mortality is high, long-term survival is not impossible. The increased risk of maternal morbidity necessitates close surveillance.

    Bronchopulmonary dysplasia is the most common morbidity of prematurity, but the validity and utility of commonly used definitions have been questioned. To compare three commonly used definitions of bronchopulmonary dysplasia in a contemporary prospective, multicenter observational cohort of extremely preterm infants. 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. 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. 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).

    2001-01-01

    Observational studies have shown an association between transiently low thyroid hormone levels in preterm infants in the first weeks of life (transient hypothyroxinemia) and abnormal neurodevelopmental outcome. Thyroid hormone therapy might prevent this morbidity. To assess whether thyroid hormone therapy in preterm infants without congenital hypothyroidism results in clinically important changes in neonatal and long term outcomes in terms of benefits and harms. The standard search strategy of the Neonatal Review Group was used. This included searches of the Oxford Database of Perinatal Trials, Cochrane Controlled Trials Register, MEDLINE, previous reviews including cross references, abstracts, conferences, symposia proceedings, expert informants and journal handsearching in the English language. All trials using random or quasi-random patient allocation, in which thyroid hormone therapy (either treatment or prophylaxis) was compared to control in premature infants. Primary clinical outcomes included measures of neurodevelopmental outcome and mortality. Assessment of trial quality, data extraction and synthesis of data, using relative risk (RR) and weighted mean difference (WMD), were performed using standard methods of the Cochrane Collaboration and its Neonatal Review Group. Nine studies were identified that compared thyroid hormone treatment to control. Four randomized and one quasi-randomized study met inclusion criteria. All studies enrolled preterm infants thyroid hormones. Four studies used thyroxine, whereas Amato 1989 used triiodothyronine. Only two studies with neurodevelopmental follow-up were of good methodology. All studies were of small size with the largest, van Wassenaer 1997, enrolling 200 infants. Meta-analysis of five studies found no significant difference in mortality to discharge (typical RR 0.70, 95% CI 0.42, 1.17) in infants who received thyroid hormone treatment compared to controls. Meta-analysis of two studies found no significant

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

  3. Neurodevelopmental Outcomes of Prenatal Stress

    Directory of Open Access Journals (Sweden)

    M. Genco Usta

    2012-03-01

    Full Text Available The influence of prenatal stress on psychopathology has been observed in many animal and human studies. In many studies, stress during prenatal period has been shown to result in negative feedback dysregulation and hyperactivity of hypothalamo-pituitary-adrenocortical axis. Prenatal stres also may cause increased risk of birth complications, startle or distress in response to novel and surprising stimuli during infancy; lower Full Scale IQs, language abilities and attention deficiency in period of 3-5 years; increased risk of attention deficit hyperactivity syndrome, anxiety symptoms, depressive disorder and impulsivity during adolescence. Additionally, timing of prenatal stress is also important and 12-22 weeks of gestation seems to be the most vulnerable period. The results underline the need for early prevention and intervention programs for highly anxious women during pregnancy. Administration of prenatal stress monitoring to public health programs or removing pregnant women who have been exposed to life events such as natural disaster, terror attack to secure areas that provide basic needs may be crucial.

    To evaluate the effects of modafinil on the intravaginal ejaculatory latency time (IELT) and patient-reported outcomes in patients with lifelong premature ejaculation (PE). Treatment-naïve lifelong PE patients were included in this proof-of-concept study. Self-estimated IELTs of the patients were recorded and the Premature Ejaculation Profile (PEP) questionnaire was administered before the initiation of on-demand modafinil 100 mg treatment. At the end of 1 month of treatment, self-estimated IELTs were recorded again, along with posttreatment PEP outcomes. Overall, 55 lifelong PE patients with a mean age of 35.07 ± 7.80 (range: 22-58) years were enrolled. Modafinil treatment modestly increased the mean IELT at the end of 1 month (24.82 ± 16.10 seconds vs 49.82 ± 31.46 seconds, P = .0001). Moreover, at the end of 1 month, patients reported in the PEP questionnaire better control over ejaculation (0.75 ± 0.67 vs 1.35 ± 0.91, P = .0001), improved satisfaction with sexual intercourse (0.98 ± 0.78 vs 1.40 ± 0.85, P = .0001), lesser personal distress (0.42 ± 0.69 vs 0.89 ± 1.01, P = .0001), and reduced interpersonal difficulty (1.69 ± 1.48 vs 1.95 ± 1.47, P = .0001). In an uncontrolled proof-of-concept study of men with treatment-naïve lifelong PE where IELT was self-reported without a stopwatch, modest improvements of both IELT and patient-reported outcome measures were observed. Future controlled clinical trials are necessary to confirm these findings. Copyright © 2016 Elsevier Inc. All rights reserved.

    Background: Invasive fungal infections cause excessive morbidity and mortality in premature neonates and severely ill infants. Methods: Safety and efficacy outcomes of micafungin were compared between prematurely and non-prematurely born infants premature [birth weight (BW) premature, received ≥1 dose of micafungin. Among premature patients, 14.5% were low BW (1500–2499 g), 36.4% very low BW (1000–1499 g) and 49.1% extremely low BW (premature)] died. Significantly more non-premature than premature patients discontinued treatment (P = 0.003). Treatment-related adverse events were recorded in 23% of patients with no difference between groups. More extremely low BW (n = 4, 15%) and very low BW (n = 8, 40%) infants experienced treatment-related adverse events than low BW (n = 0) and there was no relation to micafungin dose or duration. For a subgroup of 30 patients with invasive candidiasis, treatment success was achieved in 73% in both premature and non-premature groups. Prophylaxis was successful in 4/5 non-premature hematopoietic stem cell transplant patients. Conclusion: Micafungin has a safe profile in premature and non-premature infants with substantial efficacy. PMID:24892849

    Full Text Available The early postnatal weight loss (EPWL is highly variable in the extremely low birth weight infants (birth weight <1000 g, ELBW. It is reported to be unassociated with adverse outcomes within a range of 3- 21% of birth weight. Its wide range might have contributed to this lack of association. The aim of our paper is to study the effects of maximum EPWL, graded as low, medium and large on clinical outcomes in ELBW infants. In a retrospective cohort observational study EPWL was measured as maximum weight loss from birth weight (MWL in ELBW infants and grouped as low (5-12% moderate (18.1-12% and high (18-25%. The clinical course and complications of infants were compared between the groups. Gestational age (GA was highest and surfactant administration, peak inspiratory pressure requirement, fluid intake, urinary output, oxygen dependent days and the number of oxygen dependent infants at age 28 days were lower in the low MWL compared to the high MWL group. However, all these significant P-values declined after controlling for GA. Diabetes mellitus and pregnancy associated hypertension were not noted in mothers in high MWL group, whereas 38% of mothers in low MWL group suffered from the latter (P=0.05. Maximum postnatal transitional weight loss, assessed in the range of low, moderate and high, is not associated with adverse outcomes independent of gestational age in ELBW infants. Maternal hypertension decreases EPWL in them.

Assessment of TSH values in a subgroup of the survivors showed no difference in thyroid function between the two groups. Exposure to morphine in the neonatal period to facilitate mechanical ventilation does not seem to have any adverse effects on intelligence, motor function, or behaviour when these children are assessed at 5-6 years of age.

    Increasing survival of extremely low birth weight (ELBW; birth weight < 1000 g) infants raises a concern regarding the risks of adverse long-term outcome such as cognitive dysfunction. Few studies have reported long-term follow-up of representative regional cohorts. The objective of this study was to assess the 5-year outcome of a prospectively followed national ELBW infant cohort. Of all live-born ELBW infants (n = 351) who were delivered in the 2-year period 1996-1997 in Finland, 206 (59%) survived until the age of 5 years. Of these, 103 were born at < 27 gestational weeks (GW). A total of 172 children were assessed with neurocognitive tests (Wechsler Preschool and Primary Scale of Intelligence-Revised and a Developmental Neuropsychological Assessment [NEPSY]). Nine children with cognitive impairment and inability to cooperate in testing were not assessed. Motor development was assessed with a modified Touwen test. The rate of cognitive impairment in the ELBW survivors was 9%. The rate of cerebral palsy was 14% (19% of ELBW infants who were born at < 27 GW). The mean full-scale IQ of the assessed children was 96 +/- 19 and in children of GW < 27 was 94 +/- 19. Attention, language, sensorimotor, visuospatial, and verbal memory values of NEPSY assessment were significantly poorer compared with normal population means. Four percent needed a hearing aid, and 30% had ophthalmic findings. Of 21 children who had been treated with laser/cryo for retinopathy of prematurity, 17 (81%) had abnormal ophthalmic findings. Of the whole cohort, 41 (20%) exhibited major disabilities, 38 (19%) exhibited minor disabilities, and 124 (61%) showed development with no functional abnormalities but subtle departures from the norm. Only 53 (26%) of the total ELBW infant cohort were classified to have normal outcome excluding any abnormal ophthalmic, auditory, neurologic, or developmental findings. Being small for gestational age at birth was associated with suboptimal growth at least until

    The association between pesticide exposure and neurobehavioral and neurodevelopmental effects is an area of increasing concern. This symposium brought together participants to explore the neurotoxic effects of pesticides across the lifespan. Endpoints examined included neurobehavioral, affective and neurodevelopmental outcomes amongst occupational (both adolescent and adult workers) and non-occupational populations (children). The symposium discussion highlighted many challenges for researchers concerned with the prevention of neurotoxic illness due to pesticides and generated a number of directions for further research and policy interventions for the protection of human health, highlighting the importance of examining potential long-term effects across the lifespan arising from early adolescent, childhood or pre-natal exposure.

    To assess the natural history and contemporary outcomes in pregnancies complicated by previable preterm premature rupture of membranes (PROM). Retrospective study of all women with a singleton or twin pregnancy admitted to a single tertiary referral center who experienced preterm PROM between 20 and 23 6/7 weeks of gestation during 2004-2014 and underwent expectant management. Women electing termination of pregnancy and pregnancies complicated by major fetal anomalies were excluded. Severe neonatal morbidity was defined as a composite of bronchopulmonary dysplasia, severe neurologic injury, or severe retinopathy of prematurity. Long-term follow-up to a corrected age of 18-21 months was available for the majority of surviving neonates. Of the 140 neonates born to women with previable preterm PROM during the study period, 104 were eligible for the study. Overall 51 (49.0%, 95% confidence interval [CI] 39.4-58.6%) newborns survived to discharge, of whom 24 (47.1%, 95% CI 33.4-60.8%) experienced severe neonatal morbidity. The overall rate of long-term morbidity among surviving neonates was 23.3% (95% CI 11.7-34.9%) and was significantly higher among neonates who previously experienced severe neonatal morbidity compared with those who did not (39.1% compared with 10.0%, P=.04). The only two factors that were significantly associated with overall survival and survival without severe neonatal morbidity were gestational age at preterm PROM of 22 weeks or greater (adjusted odds ratio [OR] 12.2, 95% CI 3.3-44.8 and adjusted OR 4.8, 95% CI 1.2-19.3, respectively) and a latency period of greater than 7 days (adjusted OR 10.1, 95% CI 3.2-31.6, and adjusted OR 6.7, 95% CI 2.2-21.0, respectively). Expectant management was associated with maternal risks including placental abruption (17.3%, 95% CI 10.0-24.6%) and sepsis (4.8%, 95% CI 0.7-8.9%). Expectant management in pregnancies complicated by previable preterm PROM between 20 and 23 6/7 weeks of gestation is associated with an

    Caffeine is effective in the treatment of apnea of prematurity but it is not well known if the therapeutic concentration of the drug has an impact on other neonatal outcomes such as chronic lung disease (CLD). The aim of this study was to determine if there is an association between caffeine concentrations and the incidence of CLD in premature infants of ⩽29 weeks of gestation. A retrospective chart review of all the infants born ⩽29 weeks of gestation from 2007 to 2011, who survived until discharge or 36 weeks postmenstrual age, was conducted. Caffeine concentrations were obtained weekly on infants getting the drug. Average caffeine concentrations (ACCs) were determined for the duration of caffeine therapy and correlated with CLD, length of stay (LOS), oxygen at discharge (OD), duration of ventilation (DV) and total charges for hospitalization for each patient. Of the 222 eligible infants, 198 met the inclusion criteria. ACC for infants without CLD was 17.0±3.8 μg ml(-1) compared with infants with CLD 14.3±6.1 μg ml(-1) (P14.5 μg ml(-1)) had lower incidence of patent ductus arteriosus, lesser number of days on ventilator and oxygen, lesser need for diuretics, lower incidence of CLD, were more likely to go home without supplemental OD and had lower LOS and lower total hospital charges (all differences were significant Pcaffeine concentrations were significantly associated with decrease in CLD. Receiver operating curve analysis confirmed a significant predictive ability of caffeine concentration for CLD with a cutoff concentration of 14.5 μg ml(-1) (sensitivity of 42.6 and specificity of 86.8). The AUC (area under the curve) for the prediction of CLD was 0.632 (95% confidence interval 0.56-0.69, P=0.009). Caffeine concentrations >14.5 μg ml(-1) were strongly correlated with reduced CLD in infants born at ⩽29 weeks of gestation. Higher caffeine concentrations were associated with decreased total hospital charges, DV, OD and LOS

    There are differences in the literature regarding outcomes of premature small-for-gestational-age (SGA) and appropriate-for gestational-age (AGA) infants, possibly due to failure to take into account gestational age at birth. To compare mortality and respiratory morbidity of SGA and AGA premature newborn infants. A retrospective study was done of the 2,487 infants born without congenital anomalies at Hospital, between Jan. 1992 and Dec. 1999. Recent (1994-96) U.S. birth weight percentiles for gestational age (GA), race and gender were used to classify neonates as SGA ( 32 wk (OR = 0.41, 95% CI 0.27 - 0.63; p hospital stay was significantly higher in SGA infants born between 26-36 wks GA than AGA infants. Premature SGA infants have significantly higher mortality, significantly higher risk of developing chronic lung disease and longer hospital stay as compared to premature AGA infants. Even the reduced risk of RDS in infants born at >/=32 wk GA, (conferred possibly by intra-uterine stress leading to accelerated lung maturation) appears to be of transient effect and is counterbalanced by adverse effects of poor intrauterine growth on long term pulmonary outcomes such as chronic lung disease.

    To describe the perinatal and infant and early childhood morbidity associated with preterm premature rupture of membranes (PROM) in a cohort of twin pregnancies evaluated prospectively with neonatal follow-up to 2 years of age. This was a secondary analysis of a randomized controlled trial of magnesium sulfate for prevention of cerebral palsy. Inclusion criteria were twin gestation with preterm PROM diagnosed between 24 0/7 and 31 6/7 weeks of gestation and planned expectant management. Latency (time from membrane rupture to delivery) and perinatal outcomes were evaluated by gestational age at membrane rupture. Long-term neonatal outcomes were also analyzed. Among 151 women who met inclusion criteria, the median gestational age at preterm PROM was 28.1 weeks (range 24.1-31.6 weeks). Approximately one-third of women achieved a latency of at least 1 week. Gestational age at preterm PROM (odds ratio [OR] 0.75, 95% confidence interval [CI] 0.63-0.90 for each week after 24 weeks of gestation) and cervical dilation at admission (OR 0.66, 95% CI 0.49-0.90 for each centimeter of dilation) were inversely associated with a latency period of at least 1 week. There were no stillbirths (95% CI 0-1%), but the rate of neonatal mortality was 90 per 1,000 newborns (95% CI 57-112) with a 7.3% cerebral palsy rate among survivors (95% CI 4.4-10.3%). In twin pregnancies, preterm PROM from 24 to 31 weeks of gestation is associated with a neonatal mortality rate of 9.0% and an overall cerebral palsy rate of 7.3%. A longer latency period is associated with less advanced cervical dilation and later gestational age at PROM. LEVEL OF EVIEDENCE: II.

    Infants born extremely preterm (EP; target early intervention to those in most need. The General Movements Assessment (GMA) in early infancy has high predictive validity for neurodevelopmental outcomes in preterm infants. However, access to a GMA may be limited by geographical constraints and a lack of GMA-trained health professionals. Baby Moves is a smartphone application (app) developed for caregivers to video and upload their infant's general movements to be scored remotely by a certified GMA assessor. The aim of this study is to determine the predictive ability of using the GMA via the Baby Moves app for neurodevelopmental impairment in infants born EP/ELBW. This prospective cohort study will recruit infants born EP/ELBW across the state of Victoria, Australia in 2016 and 2017. A control group of normal birth weight (>2500 g birth weight), term-born (≥37 weeks' gestation) infants will also be recruited as a local reference group. Parents will video their infant's general movements at two time points between 3 and 4 months' corrected age using the Baby Moves app. Videos will be scored by certified GMA assessors and classified as normal or abnormal. Parental satisfaction using the Baby Moves app will be assessed via survey. Neurodevelopmental outcome at 2 years' corrected age includes developmental delay according to the Bayley Scales of Infant and Toddler Development-III and cerebral palsy diagnosis. This study was approved by the Human Research and Ethics Committees at the Royal Children's Hospital, The Royal Women's Hospital, Monash Health and Mercy Health in Melbourne, Australia. Study findings will be disseminated via peer-reviewed publications and conference presentations. Published by the BMJ Publishing Group Limited.

    There is a lack of information on long-term neurodevelopmental outcome in preterm neonates in low- and middle-income countries. To describe the developmental attainments of preterm neonates followed up for 5 years and to identify the risk factors for impairment. A prospective descriptive cohort study was undertaken in neonates of 34 weeks gestation born within a period of 12 months at a single tertiary maternity and neonatal unit in Colombo, Sri Lanka. Infants were assessed for neurodevelopment using the Bayley Infant and Toddler III® Assessments at 6, 12 and 24 months of corrected age and school readiness assessment at 5 years. Fifty-one infants were assessed at least once, 45 were assessed at 2 years and 39 had a final assessment at 5 years. Neurodevelopmental attainment deteriorated significantly in the cognitive and motor composite scores from 6 to 24 months (p < 0.05). By 5 years the number of children with delay in cognitive, language and motor domains had reduced significantly from 24 months (p < 0.05) but the cognitive skills remained most affected (10/39). At 5 years, 13 of 39 children had a confirmed diagnosis of a neurodevelopmental disorder: eight had attention deficit hyperactivity disorder, three autism spectrum disorder, one cerebral palsy and one visual impairment. Surfactant administration and retinopathy of prematurity were the most significant risks for delayed development at 5 years (p < 0.05). Deterioration of cognitive and motor composite scores over the first 24 months highlights the need for regular surveillance of premature infants. There was a discrepancy between the diagnosis of neurodevelopmental delay at 24 months and at 5 years. But the notable impact on school readiness skills requires public health initiatives to cater for the needs of these children.

    Full Text Available Abstract Background Recent reports have raised concerns that postnatal steroids may cause neuro-developmental impairment in preterm infants. This systematic review was performed with the objective of determining whether glucocorticoid therapy, to prevent or treat bronchopulmonary dysplasia, impairs neuro-developmental outcomes in preterm infants. Method A systematic review of the literature was performed. Medline was searched and articles retrieved using predefined criteria. Data from randomized controlled trials with adequate neuro-developmental follow up (to at least one year were entered into a meta-analysis to determine the effects of postnatal treatment of preterm infants with glucocorticoids. Cerebral palsy rates, and neuro-developmental impairment (developmental score more than 2SD below the mean, or cerebral palsy or blindness were analyzed. The studies were divided into 2 groups according to the extent of contamination of the results by treatment of controls with steroids after the initial study period, those with less than 30% contamination, and those with more than 30% contamination or size of contamination not reported. Results Postnatal steroid therapy is associated with an increase in cerebral palsy and neuro-developmental impairment. The studies with less contamination show a greater effect of the steroids, consistent with a real direct toxic effect of steroids on the developing central nervous system. The typical relative risk for the development of cerebral palsy derived from studies with less than 30% contamination is 2.86 (95% CI 1.95, 4.19. The typical relative risk for the development of neuro-developmental disability among followed up infants from studies with less than 30% contamination is 1.66 (95% CI 1.26, 2.19. From this subgroup of studies, the number of premature infants who need to be treated to have one more infant with cerebral palsy (number needed to harm, NNH is 7; to have one more infant with neuro-developmental

    Full Text Available This study evaluated the extent to which refractive morbidity is correlated to preterm birth or retinopathy of prematurity (ROP itself, or both, and examined the risk factors associated with refractive errors in a cohort of preterm infants with and without ROP compared with full-term infants. This longitudinal, prospective, controlled cohort study enrolled 109 infants, including 74 preterm and 35 full-term infants. Infants were divided into the following groups: no ROP, regressed ROP, laser-treated threshold ROP, and full-term. Cycloplegic refraction was determined at 6 and 24 months’ corrected age. Multiple regression models, analysis of variance (ANOVA with post hoc comparisons, paired t test, and the χ2 test were used for data analysis. ROP status was highly predictive of significant refractive errors in preterm infants. Eyes with laser-treated threshold ROP had significant myopia at both ages (mean spherical equivalent [MSE] in right eye at both refractions −0.72, −1.21 diopters [D], astigmatism (MSE −1.62, −1.80 D, and anisometropia (MSE 0.82, 1.02 D; ANOVA p  0.05. Thus, the persistent hyperopic status across ages in patients with regressed ROP and in patients without ROP differed significantly (paired t test p > 0.05 from that in the full-term infants, with a reduction in hypermetropia noted for the first 2 years of life (paired t test p < 0.05. The incidence and magnitude of significant refractive errors increased with severe ROP and with age. Although the emmetropization process of preterm birth, including regressed ROP and no ROP, differed from full-term birth in early infancy, we found no differences in the refractive status after 1 year in patients with regressed ROP and in patients without ROP, who were at risk of developing ametropia similar to that of full-term patients. Therefore, apart from laser-treated ROP, children with regressed ROP and without ROP can likely be observed with a verbal vision screening at 3

    Individuals with intellectual and developmental disabilities (IDD) experience sleep problems at higher rates than the general population. Although individuals with IDD are a heterogeneous group, several sleep problems cluster within genetic syndromes or disorders. This review summarizes the prevalence of sleep problems experienced by individuals with Angelman syndrome, Cornelia de Lange syndrome, Cri du Chat syndrome, Down syndrome, fragile X syndrome, Prader-Willi syndrome, Smith-Magenis syndrome, Williams syndrome, autism spectrum disorder, and idiopathic IDD. Factors associated with sleep problems and the evidence for sleep treatments are reviewed for each neurodevelopmental disorder. Sleep research advancements in neurodevelopmental disorders are reviewed, including the need for consistency in defining and measuring sleep problems, considerations for research design and reporting of results, and considerations when evaluating sleep treatments.

    The specific aim of this study was to evaluate the health sequelae of preterm birth on children 8 to 11years of age as compared to same age children born at term; selected variables include special health care needs, chronic conditions, and caregiver perception of health. A secondary data analysis was conducted to evaluate the health outcomes of children 8 to 11years of age who were born prematurely compared to a sample of children born at term. The 2011/2012 National Survey of Children's Health (NSCH) is a nationally representative telephone interview survey of parents/caregivers of children 0 to 17years of age. Preterm birth was determined by parent report of birth more than 3weeks early. Utilizing the Children with Special Health Care Needs (CSHCN) Screener, 35% of children born prematurely, compared to 24% of children born at term were identified as having a special health care need. The 5 most prevalent conditions were the same in both groups of 8 to 11year old children and in the larger total sample of children 2 to 17years of age. However 82% of children born prematurely were described by parents as having excellent or very good health. Premature birth places children at increased risk for conditions that impede the crucial activities of childhood (education, psychosocial development and play). These conditions may require both medications and increased health care services. Understanding the relationship between preterm birth and ongoing health risks has the potential to inform the health care providers' ability to provide care that maximizes the potential of children born prematurely. Health care providers need to be cognizant of this risk, utilizing early screening and encouraging intervention and family supports. Copyright © 2016 Elsevier Inc. All rights reserved.

    The purpose of this study is to determine the frequency of emotional, behavioral, and learning disorders in children exposed in utero to hyperemesis gravidarum (HG) and to identify prognostic factors for these disorders. Neurodevelopmental outcomes of 312 children from 203 mothers with HG were compared to neurodevelopmental outcomes from 169 children from 89 unaffected mothers. Then the clinical profiles of patients with HG and a normal child outcome were compared to the clinical profiles of patients with HG and a child with neurodevelopmental delay to identify prognostic factors. Binary responses were analyzed using either a Chi-square or Fisher Exact test and continuous responses were analyzed using a t-test. Children exposed in utero to HG have a 3.28-fold increase in odds of a neurodevelopmental diagnosis including attention disorders, learning delay, sensory disorders, and speech and language delay (Ppregnancies, only early onset of symptoms (prior to 5 weeks gestation) was significantly linked to neurodevelopmental delay. We found no evidence for increased risk of 13 emotional, behavioral, and learning disorders, including autism, intellectual impairment, and obsessive-compulsive disorder. However, the study was not sufficiently powered to detect rare conditions. Medications, treatments, and preterm birth were not associated with an increased risk for neurodevelopmental delay. Women with HG are at a significantly increased risk of having a child with neurodevelopmental delay. Common antiemetic treatments were not linked to neurodevelopmental delay, but early symptoms may play a role. There is an urgent need to address whether aggressive treatment that includes vitamin and nutrient supplementation in women with early symptoms of severe nausea of pregnancy decreases the risk of neurodevelopmental delay.

    Full Text Available Introduction. Pre-term premature rupture of membranes (PPROM is one of the leading causes of perinatal morbidity and mortality. This complication is diagnosed in 3% of pregnant women in Kazakhstan, and it is the leading cause of pre-term deliveries. The aim of this study was to determine the outcomes of pregnancies complicated by PPROM in gestation periods between 24 to 32 weeks among three institutions in Kazakhstan.Methods. This is descriptive analysis of 154 cases with PPROM observed between 24 to 32 weeks of gestation at Perinatal Centers #2 and #3 and the National Research Center for Maternal and Child Health, Astana, Kazakhstan. Cases were selected on the basis of retrospective chart review where PPROM diagnosis occurred in 2013. Descriptive statistics were utilized for data analysis.Results. The most frequent complications associated with PPROM were threat of miscarriage (13.6% of cases and chronic placental insufficiency (7.8%. The mean time between PPROM and onset of spontaneous labor was 12.1 ± 2.3 days.  Spontaneous labor within 3 days after PPROM started in patients with an amniotic fluid index of 3.0 ± 0.2 cm. Complications experienced by PPROM women during delivery and early postpartum period included: precipitous labor (6.4%, weakness of labor activity (16.2%, atonic hemorrhage (1.2%, and chorioamnionitis (3.2%. 37.6% of newborns in this study were admitted to the Intensive Care Unit. Their health complications included pneumonia (7.7%, conjunctivitis (1.3%, omphalitis and infectious-toxic shock (3.8%, intraventricular hemorrhage  (7.8%, and respiratory distress (10.3% .Conclusion. Thus, preterm rupture of membranes is associated with preterm delivery and an increase of neonatal morbidity. Therefore, it is necessary to find ways to effectively manage PPROM, including developing new techniques to restore the amniotic fluid volume in women experiencing PPROM during 24 to 32 weeks of gestation.

    To determine the prevalence and the effect of premature luteinization in GnRH antagonist IVF-ET cycles. Prospective observational study. In vitro fertilization-embryo transfer (IVF-ET) program at the Instituto Valenciano de Infertilidad. Eighty-one infertile patients undergoing controlled ovarian hyperstimulation with gonadotropins and GnRH antagonist for IVF-ET. Gonadotropin-releasing hormone (GnRH) antagonist was administered from stimulation day 6. Serum P, E(2), and LH were determined on the day of hCG administration. Cycles were grouped according to serum P level on the day of hCG administration ( or =1.2 ng/mL). Clinical pregnancy and implantation rates were determined. The incidence of premature luteinization was 38.3%. Total recombinant FSH dose and stimulation days differed significantly between the groups. Pregnancy rate (25.8% vs. 54.0%) and implantation rate (13.8% vs. 32.0%) were significantly lower in the premature luteinization group. Premature luteinization during GnRH antagonist IVF-ET cycles is a frequent event that is associated with lower pregnancy and implantation rates. Progesterone elevations are not related to serum LH levels and may reflect the mature granulosa cell response to high FSH exposure.

    Full Text Available Over the past few decades, the advancements in the perinatal and neonatal intensive care have led to a significant survival of premature infants. However neurodevelopmental outcome still remains the topical issues of concern. Developmental care is an approach that is aimed to reduce the mismatches between extra- and intra-uterine environments, decrease the stress of preterm newborns in neonative intensive care units, and thus promote optimal neurobehavioral development of the infant. The Newborn Individualized Developmental Care and Assessment Program (NIDCAP model was developed as a clinical framework for the implementation of developmental care. The model focuses on detailed reading of each individual infant’s behavioral cues. By observing the child during the routine manipulation performance (before, during and after and a detailed description of his/her behavioral responses, a professional can assess the ability of the infant’s immature nervous system to tolerate the environment and care manipulations. Such evaluation will enable to determine the adequacy of environmental conditions and care manipulations to baby’s opportunities and needs, with their subsequent correction and adaptation. NIDCAP’s aim is to support the child in its increasing tolerance to stimuli and to minimize stressful events and manipulation. With the help of NIDCAP approaches in neonatal care, medical staff study how to read infants’ behavior, hear their voice and understand them.

    Full Text Available Abstract Background There are differences in the literature regarding outcomes of premature small-for-gestational-age (SGA and appropriate-for gestational-age (AGA infants, possibly due to failure to take into account gestational age at birth. Objective To compare mortality and respiratory morbidity of SGA and AGA premature newborn infants. Design/Methods A retrospective study was done of the 2,487 infants born without congenital anomalies at ≤36 weeks of gestation and admitted to the neonatal intensive care unit (NICU at John Dempsey Hospital, between Jan. 1992 and Dec. 1999. Recent (1994–96 U.S. birth weight percentiles for gestational age (GA, race and gender were used to classify neonates as SGA (th–90th percentile for GA. Using multivariate logistic regression and survival analyses to control for GA, SGA and AGA infants were compared for mortality and respiratory morbidity. Results Controlling for GA, premature SGA infants were at a higher risk for mortality (Odds ratio 3.1, P = 0.001 and at lower risk of respiratory distress syndrome (OR = 0.71, p = 0.02 than AGA infants. However multivariate logistic regression modeling found that the odds of having respiratory distress syndrome (RDS varied between SGA and AGA infants by GA. There was no change in RDS risk in SGA infants at GA ≤ 32 wk (OR = 1.27, 95% CI 0.32 – 1.98 but significantly decreased risk for RDS at GA > 32 wk (OR = 0.41, 95% CI 0.27 – 0.63; p Conclusions Premature SGA infants have significantly higher mortality, significantly higher risk of developing chronic lung disease and longer hospital stay as compared to premature AGA infants. Even the reduced risk of RDS in infants born at ≥32 wk GA, (conferred possibly by intra-uterine stress leading to accelerated lung maturation appears to be of transient effect and is counterbalanced by adverse effects of poor intrauterine growth on long term pulmonary outcomes such as chronic lung disease.

    Full Text Available Contemporary aetiopathogenetic considerations, based on neuro-imaging genetic and developmental neurobiology studies, suggest neurodevelopmental origin of schizophrenia. Several lines of evidence including structural abnormalities on in vivo brain imaging, the excess of prenatal and obstetric complications and the association of congenital and minor physical anomalies with schizophrenia, strongly indicate the neurodevelopmental pathogenesis of schizophrenia. On the other hand, controversial concept of psychotic continuum suggests schizophrenia and depression sharing the same genetic contribution to the pathogenesis. If this would be the case, depression could also be considered as neuro developmental disorder. The aims of the study were to investigate the association between: a pregnancy and birth complications (PBC, and b minor physical anomalies (MPA and schizophrenia or depression. Experimental groups consisted of 60 schizophrenic, 28 major depression patients and 30 healthy controls. All patients were diagnosed according to DSM-IV. Schizophrenic group was divided with regard to PANSS score into positive (n=32 and negative form (n=28 subgroups. PBC information were gathered from maternal recall while MPA were examined by using Waldrop scale for adults. The results showed that negative and positive schizophrenic subgroups had significantly more PBC than depressive group (p<0,05, as well than controls (p<0,001; p<0,05; respectively. There was no significant trend for more PBC in negative than in positive subgroup. All schizophrenic patients had higher rates of MPA than depressives (p<0,05. This trend for more MPA was not significant in comparison with healthy controls. These findings suggest that schizophrenia, especially its negative forms, could be considered as a member of the spectrum of neuro developmental disorders, which does not seem to be the case with depression. PBC and MPA could also be valuable in evaluation of risks for

    The aims of the study were to assess the long-term safety and compare neurodevelopmental outcomes in school-age children born prematurely who received inhaled nitric oxide or placebo during the first week of life in a randomized, double-blinded study. Children treated with inhaled nitric oxide had previously been shown to have decreased intraventricular haemorrhage and periventricular leukomalacia as newborns and decreased cognitive impairment at 2 years (L.W. Doyle and P.J. Anderson. (2005) Arch Dis Child Fetal Neonatal Ed, 90, F484-F8). It is follow-up study of medical outcomes, neurodevelopmental assessment and school readiness in 135 of 167 (81%) surviving premature infants seen at 5.7±1.0 years. Compared to placebo-treated children (n=65), iNO-treated children (n=70) demonstrated no difference in growth parameters, school readiness or need for subsequent hospitalization. However, iNO-treated children were less likely to have multiple chronic morbidities or technology dependence (p=0.05). They also had less functional disability (p=0.05). These results demonstrate the long-term safety of iNO in premature infants. Furthermore, iNO treatment may improve health status by decreasing the incidence of severe ongoing morbidities and technology dependence and may also decrease the incidence of educational and community functional disability of premature infants at early school age. © 2010 The Author(s)/Acta Paediatrica © 2010 Foundation Acta Paediatrica.

    Objective: A large Danish birth cohort was used to test the independent and joint effects of perinatal measures associated with premature birth as predictors of the development of alcoholism in male and female subjects. Method: Subjects were born at the Copenhagen University Hospital between 1959 and 1961 (N = 9,125). A comprehensive series of measures was obtained for each of the 8,109 surviving and eligible infants before birth, during birth, shortly after birth, and at 1 year. The adult alcoholism outcome was defined as any ICD-10 F10 diagnosis (Mental and behavioral disorders due to alcohol use) or an equivalent ICD-8 diagnosis found in the Danish Psychiatric Central Research Register or the Municipal Alcohol Clinics of Copenhagen by 2007. Results: Multiple perinatal markers of premature birth independently predicted the development of an alcoholism diagnosis in male (n = 310) but not female (n = 138) subjects. Logistic regression modeling with a global prematurity score, adjusted for social status, maternal smoking, and gender, indicated a significant association of prematurity score for males (p premature birth are associated with gender-specific effects on the development of alcoholism in the male baby: small, premature, or growth-delayed male babies appear to be selectively vulnerable to alcoholic drinking years later. The findings implicate neurodevelopmental influences in alcoholism pathophysiology in males and suggest the possibility of distinct, gender-specific pathways in the etiology of severe problem drinking.

    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%

    This historical cohort study aimed to assess the relationship between antenatal maternal C-reactive protein (CRP) level and neonatal outcome preterm premature rupture of membranes (PPROM). We reviewed the records of 70 singleton pregnancies with PPROM between 24 and 34 weeks. Maternal CRP levels of neonates with respiratory distress syndrome, neonatal sepsis, grade 3-4 intraventricular haemorrhage and stage 2-3 necrotizing enterocolitis, perinatal mortality were compared with those without these complications. Administration of corticosteroid, tocolysis for two days and prophylactic antibiotics (intravenous ampicillin/sulbactam, and oral azithromycin) were the standard management protocol. The mean age at PPROM was 29 weeks 2 days (±3 weeks), the mean age at birth was 30 weeks 5 days (±20 days). CRP levels were not different between groups. Uni/multivariate analysis showed that maternal CRP levels were not related with neonatal outcomes. Neonatal complications in PPROM are related with the degree of prematurity and maternal WBC counts.

    We studied the effects of administering exogenous surfactant for the treatment of respiratory distress in premature neonates (born before 37 weeks of gestational age [GA]) and compared the role of different risk factors on the outcome as well as survival rate. All the neonates (242) suffered from moderate to severe respiratory distress, identified by clinical signs, chest X-ray, respiratory distress syndrome (RDS) score >6, and blood gas measurements. All the neonates included were treated by administering surfactant (Beractant or Poractant alfa, dosage 100 mg/kg). The INSURE method was "successful" in 74% of patients, meaning there was no need for a second dose of surfactant or mechanical ventilation repetition. The factors that determined the "success" (Table II) were as follows: type of delivery, weight, GA, and number of fetuses. The factors affecting survival were: number of fetuses, mechanical ventilation dependency, pregnancy complications, and type of surfactant. The INSURE method reduced mortality (91.3% survived).

    To investigate the relationship between fetal presentation at the time of admission for preterm premature rupture of membranes (PROM) and perinatal outcomes, including gestational latency, among women in a large and well-characterized population with preterm PROM at less than 32 weeks of gestation. This was a secondary analysis of data from women randomized to receive magnesium sulfate compared with placebo in the previously reported Maternal-Fetal Medicine Units Network Beneficial Effects of Antenatal Magnesium Sulfate (1997-2004) trial. Women with a singleton gestation and preterm PROM were included. Fetal presentation at the time of randomization was recorded. Associations of fetal position (cephalic compared with noncephalic) with perinatal outcomes were compared using χ, Fisher exact, and Wilcoxon rank-sum tests. Perinatal outcomes included gestational latency, abruption, and neonatal morbidity and mortality. Multivariable regression (logistic, linear, and Cox) analyses were used to adjust for potential confounding factors. Of the 1,767 eligible women, 439 (24.5%) had a noncephalic presentation. Noncephalic presentation was associated with an earlier median gestational age at the time of preterm PROM (26.6 compared with 28.4 weeks of gestation, Ppreterm PROM are at greater risk of neonatal death.

    Patients with PPROM are at risk for a variety of outcomes, including chorioamnionitis (CA), placental abruption (PA), or preterm labor (PTL). Competing risk regression can analyze a cohort's risk of individual outcomes while accounting for ongoing deliveries secondary to competing events. A secondary analysis of the subjects from MFMU BEAM study of neuroprotection after preterm birth (BEAM) with conservative PPROM management. Deliveries were categorized as: PA, CA, PTL, "elective" or "indicated". The association between outcomes of PA, CA or PTL and clinical predictors of twins, ethnicity, parity, gestational age at rupture, bleeding, contractions, cervical dilation, preterm birth history, weight, and genitourinary infections were evaluated via competing risk regression. 1970 subjects were included. The significance and directionality of predictors varied according to specific outcomes. Patients with twins had an increased PTL hazard (1.85) though reductions in CA- (0.66) or PA-specific (0.56) hazards. Decreased latency in African-Americans was almost entirely due to an increased CA hazard (1.44) without a significant association with PTL. Increasing gestational age at membrane rupture was associated with a decreasing hazard of CA although increasing hazard of PTL. For patients with PPROM, the hazards associated with different clinical predictors vary according to exact outcomes.

    To compare the neonatal outcome in twin gestations complicated by prolonged preterm premature rupture of membranes (PPROM). Between the years 2000 and 2010 we identified 48 women with twin pregnancies who were diagnosed as having PPROM and a latency period to delivery >24h. We compared the neonatal morbidity and mortality between the presenting and non-presenting twins, assuming that the rupture occurred in the lower sac. Importantly, in 30 women we were able to identify the location of the ruptured sac by ultrasound examination demonstrating oligohydramnion. In these 30 cases, neonatal outcome of fetuses in the ruptured sac and those in the intact sac were compared. The median gestational age was 31 weeks (range 28-33) with a median latency period between PPROM and delivery of 9 days (range 1-18). Of the identified ruptures 90% (27/30) occurred in the lower sac (presenting twin). There was no significant difference between the presenting and non-presenting twin in terms of neonatal morbidity and mortality. Moreover, no difference was found when fetuses with ruptured sac were compared to those with intact membrane sac. Importantly, the outcomes were not affected by the length of the latency period. The current study results demonstrated that the outcome of fetuses exposed to prolonged preterm rupture of membranes is similar to that of fetuses with intact membranes. Our data suggest that rupture of membranes per se did not cause any deleterious clinical manifestations or lead to clinical discordant inflammation and poor neonatal outcome, supporting a conservative management of twin pregnancies with PPROM.

    We sought to (1) evaluate at 2 years the postsurfactant era developmental outcome of children who were born before 33 weeks of gestational age (GA) in the Nord-Pas-de-Calais area in France in 1997 and (2) identify risk factors of poor developmental quotient (DQ). Children were part of the EPIPAGE study, which included all of these births in 9 French regions. A prospective observational study was conducted of all births before 33 weeks in 1997. Risk factors of poor DQ were obtained from a multiple linear regression, and results were expressed as DQ differences with 95% confidence intervals. A total of 546 births were included in the study. A total of 461 (84.4%) had a clinical evaluation at 2 years of age, and 380 (69.6%) had an assessment with the use of the Brunet-Lezine scale of infant development. Their mean GA was 29.9 weeks (29.7-30.1 weeks), and mean birth weight was 1378 g (1338-1418 g). A total of 9% had a recognizable pattern of cerebral palsy, 0.2% were blind, and 0.8% required hearing aids. The mean DQ was 94 +/- 11 and decreased from 97 at 32 weeks to 86 at 24 to 25 weeks. After multivariate analysis, children who were born at 24 to 25 weeks had a mean DQ reduction of 11 points (-20 to -1) compared with those who were born at 32 weeks, but minor differences were found from 26 to 32 weeks. Boys had a DQ 4 points lower than girls (-7 to -1). In this study, the outcome of extremely preterm infants was poor. After 25 weeks, outcome was related mainly to the sociocultural level of the family and to the presence of severe cerebral ultrasound abnormalities. Consequently, in the postsurfactant era, we have to propose follow-up programs to children who are born extremely preterm and to concentrate our efforts on children with less-than-optimal social and family setting.

    The purpose of this study was to determine the prevalence of Ureaplasma urealyticum (UU) and Mycoplasma hominis (MH) in patients with preterm labor or preterm premature rupture of membranes (PPROM) and to determine the effect of these organisms on pregnancy outcomes based on the density of colonization. The study group consisted of 184 women with preterm labor or PPROM. Vaginal cultures for UU and MH were performed for all patients at admission, and the placentas were histologically evaluated after delivery. The prevalence of positive vaginal fluid cultures for genital mycoplasma was 62.5% (112/179). This group included 99 patients carrying only UU and 13 carrying both organisms. No patients were found to carry only MH. Compared to patients only positive for UU, patients with both organisms showed significantly decreased gestational age at birth and birth weight, and significant increases in the incidences of preterm birth, NICU admissions and histologic chorioamnionitis. Vaginal MH tends to be detected with UU, and patients carrying both organisms simultaneously had more severe adverse pregnancy outcomes compared to patients in preterm labor or PPROM who were only positive for UU.

    Threatened premature labor (TPL) is a severe obstetric complication which affects the mental and physical health of both the mother and fetus. Family resilience may have protective role against psychological distress in women experiencing these pregnancy complications. There may be resilience related risk factors in TPL women, and interplays may exist among psychological variables and within couples. This study aims to examine psychological outcomes influenced by different levels of resilience, and explore psychological interactions in TPL women, spouses, and between women and spouses. Six validated questionnaires were used to measure the psychological outcomes (Connor-Davidson resilience scale CD-RISC, Edinburgh postnatal depression scale EPDS, positive and negative affect scale PANAS, pregnancy pressure scale PPS, simplified coping style questionnaire SCSQ, social support rating scale SSRS) in 126 TPL women hospitalized in three tertiary hospitals and 104 spouses in Southwest China. Low resilient women had significantly more complicated placenta praevia, longer pediatric observation, more pressure than high resilient women. They also had significantly less active coping and positive affect, more negative affect and depression compared to high resilient women and their spouses. Although the socio-demographic characteristics of both TPL women and spouses and psychometric parameters of spouses had no significant differences, the prevalence rates of depression in spouses were notable. Compared with spouses, TPL women had a more complex interaction among these psychometric factors, with women's resilience negatively associated with their partners' negative affect, and their pressure positively correlated with pressure and negative affect of spouses. Pregnancy complicated with placenta praevia and pediatric observation may be risk factors for resilience of women with TPL. Maternal resilience has an important impact on the psychological outcomes in TPL women. A

    A telemedicine program was developed between the Children's National Medical Center (CNMC) in Washington, DC, and the Sheikh Khalifa Bin Zayed Foundation in the United Arab Emirates (UAE). A needs assessment and a curriculum of on-site training conferences were devised preparatory to an ongoing telemedicine consultation program for children with neurodevelopmental disabilities in the underserved eastern region of the UAE. Weekly telemedicine consultations are provided by a multidisciplinary faculty. Patients are presented in the UAE with their therapists and families. Real-time (video over Internet protocol; average connection, 768 kilobits/s) telemedicine conferences are held weekly following previews of medical records. A full consultation report follows each telemedicine session. Between February 29, 2012 and June 26, 2013, 48 weekly 1-h live interactive telemedicine consultations were conducted on 48 patients (28 males, 20 females; age range, 8 months-22 years; median age, 5.4 years). The primary diagnoses were cerebral palsy, neurogenetic disorders, autism, neuromuscular disorders, congenital anomalies, global developmental delay, systemic disease, and epilepsy. Common comorbidities were cognitive impairment, communication disorders, and behavioral disorders. Specific recommendations included imaging and DNA studies, antiseizure management, spasticity management including botulinum toxin protocols, and specific therapy modalities including taping techniques, customized body vests, and speech/language and behavioral therapy. Improved outcomes reported were in clinician satisfaction, achievement of therapy goals for patients, and requests for ongoing sessions. Weekly telemedicine sessions coupled with triannual training conferences were successfully implemented in a clinical program dedicated to patients with neurodevelopmental disabilities by the Center for Neuroscience at CNMC and the UAE government.

  10. Premature ejaculation.

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

    Preterm premature rupture of the membranes (PPROM) remains the leading cause of preterm deliveries and neonatal mortality and morbidity. The current cohort study sought to retrospectively examine perinatal outcomes in cases of PPROM < 34 weeks' gestation that were managed conservatively from 2010 to 2012 and to identify risk factors for short-term neonatal outcomes. Subjects were 510 pregnancies consisting of 114 twin and 396 singleton pregnancies. Clinical chorioamnionitis occurred in 17.8% of the pregnancies. Neonatal mortality was 7.4%, the rate of major neonatal conditions was 40%, and the rate of NICU admission was 72.9%. The latency period exceeded 48 h in 62.5% of the pregnancies and 7 days in 24.3% of the pregnancies. Twin pregnancies had a shorter latency period than singleton pregnancies (median of 2 days versus 4 days, p < 0.001). Pregnancies complicated with early vaginal bleeding had a higher neonatal mortality (13.95% vs. 6.36%, p = 0.013) and morbidity (51.16% vs. 38.32%, p = 0.024), fewer weeks of gestation at PPROM (p = 0.029). Multivariate logistic regression analysis revealed that weeks of gestation at PPROM (OR: 0.953, 95% CI: 0.939-0.966, p < 0.001) and a latency period (OR: 0.948, 95%CI: 0.926-0.970, p < 0.001) were associated with neonatal mortality or morbidity. A twin pregnancy (OR: 0.319, 95% CI: 0.17-0.6, p < 0.001) and weeks of gestation at PPROM (OR: 0.737, 95% CI: 0.66-0.822, p < 0.001) were associated with the latency period. Gestational age at PPROM, a twin pregnancy, and the latency period are associated with neonatal mortality and morbidity.

    Pentobarbital is known to affect cerebral metabolism; pentobarbital sedation is, however, frequently used for MR imaging and MR spectroscopy, especially in children. Accurate assessment of the brain metabolite levels is important, particularly in neonates with suspected brain injury. We investigated whether pentobarbital sedation has any effect on the ratios of spectral metabolites lactate, N-acetylaspartate, or choline in a group of premature neonates. MR spectroscopy was performed in 43 premature neonates, all with normal concurrent MR imaging and normal neurodevelopmental outcome at 12 months of age. Of those neonates, 14 (33%) required pentobarbital (Nembutal 1 mg/kg) sedation during MR spectroscopy; the remaining 29 neonates did not receive any sedation. Ratios of lactate, choline, and N-acetylaspartate were calculated in the basal ganglia, thalami, and corticospinal tracts and compared between those neonates with and without sedation. Small amounts of brain lactate were detected in all of the premature neonates. The basal ganglia lactate/choline and lactate/N-acetylaspartate ratios were significantly lower, by 17% and 25% respectively, in the neonates with pentobarbital sedation compared with the age-matched neonates without sedation (P Sedation did not affect the lactate level in the thalami or the corticospinal tracts. The N-acetylaspartate/choline ratios were unaffected by pentobarbital sedation. Pentobarbital sedation is associated with lower lactate/choline and lactate/N-acetylaspartate ratios in the basal ganglia of premature neonates, as determined by proton MR spectroscopy. Investigators should be aware of this phenomenon for accurate interpretation of their MR spectroscopy results.

    The goals of early nutrition in preterm infants are to provide all the necessary vital nutrients, achieve extra-uterine growth rates similar to fetuses of the same gestational age, and support functional neurodevelopmental outcomes that are comparable to those of infants born at term. It is vital to provide nutrition that will maximally support brain growth and development, but over-feeding with accelerated growth, fat accumulation and long-term metabolic consequences should also be avoided. Because the morbidity associated with prematurity increases nutritional and energetic demands, the basic approach is of providing early intensive nutrition. Protein is the main driving force for growth and brain development. Since deficits in protein occur from the first day of extra-uterine life, sufficient quantities of parenteral amino acids should be provided from the first hours of life. With protein and carbohydrates, enough energy should also be provided, via concomitant early administration of intravenous lipid emulsions. Early initiation of enteral feeding with advancement to full enteral nutrition is associated with better maturation of the gut and better neuro-developmental outcomes. Human milk is the best food for preterm babies, although enrichment may be needed.

    Prematurely born children are at increased risk for language deficits at school age and beyond, but the neurobiological basis of these findings remains poorly understood. Thirty-one PT adolescents (600-1250g birth weight) and 36 T controls were evaluated using an fMRI passive language task and neurodevelopmental assessments including: the Wechsler Intelligence Scale for Children-III (WISC-III), the Peabody Picture Vocabulary Test-Revised (PPVT-R), the Comprehensive Test of Phonological Processing (CTOPP) and the Test of Word Reading Efficiency (TOWRE) at 16years of age. Neural activity was assessed for language processing and the data were evaluated for connectivity and correlations to cognitive outcomes. PT subjects scored significantly lower on all components of the WISC-III (padolescents engage a dorsal right hemisphere region for language at age 16years. Those with the greatest cognitive deficits demonstrate increasing reliance on this alternate pathway. Copyright 2010 Elsevier Inc. All rights reserved.

    Full Text Available BACKGROUND: Atrial premature complexes (APC are among the most frequently encountered electrocardiographic abnormalities. However, their prognostic value among healthy individuals is unclear. This study aimed to clarify the role of APC in predicting cardiovascular events in a large Japanese community cohort using long-term follow-up data. METHODS: National Integrated Project for Prospective Observation of Non-communicable Disease And its Trends in the Aged, 1990-2005, (NIPPON DATA 90 was a large cohort study of cardiovascular disease (CVD in Japan. A total of 7692 otherwise healthy participants with no history of myocardial infarction, stroke, atrial fibrillation, or atrial flutter were enrolled (men, 41.5%; mean age, 52.5 ± 13.7 years. RESULTS: A total of 64 (0.8% participants had at least one beat of APC on screening 12-lead electrocardiogram. During the follow-up of 14.0 ± 2.9 years (total, 107,474 patient-years, 338 deaths occurred due to CVD. The association between APC and CVD outcome was assessed using Cox proportional hazard models. Cox regression analysis revealed that the presence of APC was an independent predictor for CVD deaths (HR: 2.03, 95% CI: 1.12-3.66, P = 0.019. The association of APC on CVD death was more evident in participants with hypertension (P-value for interaction, 0.03. CONCLUSIONS: APC recorded during the screening electrocardiogram are significantly associated with an increased risk of CVD deaths in a Japanese community-dwelling population and are a strong prognostic factor for hypertensive participants.

  19. Higher O-GlcNAc Levels Are Associated with Defects in Progenitor Proliferation and Premature Neuronal Differentiation during in-Vitro Human Embryonic Cortical Neurogenesis

    Full Text Available The nutrient responsive O-GlcNAcylation is a dynamic post-translational protein modification found on several nucleocytoplasmic proteins. Previous studies have suggested that hyperglycemia induces the levels of total O-GlcNAcylation inside the cells. Hyperglycemia mediated increase in protein O-GlcNAcylation has been shown to be responsible for various pathologies including insulin resistance and Alzheimer's disease. Since maternal hyperglycemia during pregnancy is associated with adverse neurodevelopmental outcomes in the offspring, it is intriguing to identify the effect of increased protein O-GlcNAcylation on embryonic neurogenesis. Herein using human embryonic stem cells (hESCs as model, we show that increased levels of total O-GlcNAc is associated with decreased neural progenitor proliferation and premature differentiation of cortical neurons, reduced AKT phosphorylation, increased apoptosis and defects in the expression of various regulators of embryonic corticogenesis. As defects in proliferation and differentiation during neurodevelopment are common features of various neurodevelopmental disorders, increased O-GlcNAcylation could be one mechanism responsible for defective neurodevelopmental outcomes in metabolically compromised pregnancies such as diabetes.

    Premature rupture of the membranes (PROM) in pregnancy refers to rupture of membranes of the amniotic sac and chorion. The aim of the study was to review the literature and analyze the course of pregnancy (primipara) complicated by the premature rupture of the membranes, and consequent loss of amniotic fluid after 19 weeks of gestation. A 27-year old primiparous patient was admitted to the Gynaecology and Obstetrics University Hospital in Poznań on 9 December 2010, due to suspected premature rupture of the membranes. On presentation, foetal development was at 19 weeks gestation. Standard clinical investigations included ultrasonography, amniotic fluid index measurements and laboratory blood tests. Ultrasonography confirmed the size of the foetus to be normal for the gestational age. However, no amniotic fluid pockets were visible and the amniotic fluid index was 0 cm. The patient was hospitalized on multiple occasions and as a result a decision was made to end the pregnancy prematurely by means of a caesarean section at 32 weeks of gestation. Longer-term observation of the newborn indicated that one year following delivery, the development of the baby was normal, and thus far no neurological injuries or complications have been observed. The pregnancy was ultimately successfully completed with the delivery of a healthy newborn at 32 weeks of gestation. A regime involving rigorous bed rest and antibiotic administration can positively extend the duration of pregnancies complicated by premature rupture of the membranes.

  4. Cerebellum of the Premature Infant: Rapidly Developing, Vulnerable, Clinically Important

    2009-01-01

    Brain abnormality in surviving premature infants is associated with an enormous amount of neurodevelopmental disability, manifested principally by cognitive, behavioral, attentional, and socialization deficits, most commonly with only relatively modest motor deficits. The most recognized contributing neuropathology is cerebral white matter injury. The thesis of this review is that acquired cerebellar abnormality is a relatively less recognized but likely important cause of neurodevelopmental disability in small premature infants. The cerebellar disease may be primarily destructive (eg, hemorrhage, infarction) or primarily underdevelopment. The latter appears to be especially common and relates to a particular vulnerability of the cerebellum of the small premature infant. Central to this vulnerability are the extraordinarily rapid and complex developmental events occurring in the cerebellum. The disturbance of development can be caused either by direct adverse effects on the cerebellum, especially the distinctive transient external granular layer, or by indirect remote trans-synaptic effects. This review describes the fascinating details of cerebellar development, with an emphasis on events in the premature period, the major types of cerebellar abnormality acquired during the premature period, their likely mechanisms of occurrence, and new insights into the relation of cerebellar disease in early life to subsequent cognitive/behavioral/attentional/socialization deficits.

Its etiology is often multi factorial and diagnosis of idiopathic forms requires exclusion of other underlying diseases. Despite being a self-limiting condition which regresses with the maturation of the newborn, possible long-term effects of recurring apneas and the degree of desaturation and bradycardia who may lead to abnormal neurological outcome are not yet clarified. Therefore AOP needs careful evaluation of its etiology and adequate therapy that can be both pharmacological and non-pharmacological. Proceedings of the 9th International Workshop on Neonatology · Cagliari (Italy · October 23rd-26th, 2013 · Learned lessons, changing practice and cutting-edge research

    ATP7A mutations impair copper metabolism resulting in three distinct genetic disorders in humans. These diseases are characterized by neurological phenotypes ranging from intellectual disability to neurodegeneration. Severe ATP7A loss-of function alleles trigger Menkes disease, a copper deficiency condition where systemic and neurodegenerative phenotypes dominate clinical outcomes. The pathogenesis of these manifestations has been attributed to hypoactivity of a limited number of copper-dependent enzymes, a hypothesis that we refer as the oligoenzymatic pathogenic hypothesis. This hypothesis, which has dominated the field for 25 years, only explains some systemic Menkes phenotypes. However, we argue that this hypothesis does not fully account for the Menkes neurodegeneration or neurodevelopmental phenotypes. Here, we propose revisions of the oligoenzymatic hypothesis that could illuminate the pathogenesis of Menkes neurodegeneration and neurodevelopmental defects through unsuspected overlap with other neurological conditions including Parkinson’s, intellectual disability, and schizophrenia.

    We examined comorbid psychiatric and neurodevelopmental disorders in fifty adult males (mean age 30 years) with Asperger syndrome (AS) diagnosed in childhood and followed up prospectively for almost two decades (13-26 years). Only three of the 50 men had never met criteria for an additional psychiatric/neurodevelopmental diagnosis and more than half had ongoing comorbidity (most commonly either ADHD or depression or both). Any psychiatric comorbidity increased the risk of poorer outcome. The minority of the AS group who no longer met criteria for a full diagnosis of an autism spectrum disorder were usually free of current psychiatric comorbidity. The high rate of psychiatric/neurodevelopmental comorbidities underscores the need for a full psychiatric/neurodevelopmental assessment at follow-up of males with AS.

    This study examined the item interpretability and rating scale use of the Pediatric Evaluation of Disability Inventory-Patient-Reported Outcome (PEDI-PRO) by young people with developmental disabilities. The PEDI-PRO assesses the functional performance of discrete functional tasks in the context of everyday life situations. A two-phase cognitive interview design was implemented with a convenience sample of 37 young people (mean age 19y, SD 2y 5mo; 13 males and 24 females; 68% with intellectual disability) with developmental disabilities. In phase I, 182 item candidates were each reviewed by an average of four young people. In phase II, 103 items were carried forward or revised and each reviewed by an average of seven additional young people. Two raters coded responses for intended item interpretation and performance quality; codes were analysed using descriptive statistics. Qualitative analysis explored young people's self-evaluation process. Items were interpreted as intended by most young people (mean 86%). Young people can use PEDI-PRO response categories appropriately to describe their performance: 94% of positive performance descriptions coincided with a positive response category choice; 73% of negative descriptions coincided with a negative response category choice. Young people interpreted items in a literal manner, and their self-evaluation incorporated the use of supports that facilitate functional performance. The PEDI-PRO's measurement framework appears to support the self-evaluation of functional performance of young people with developmental disabilities. © 2017 Mac Keith Press.

    2007-12-01

    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 1 dozen descriptive, and a few quasirandomized, studies in the past 25 years. Studies on neurodevelopmental outcomes have reported significantly positive effects for human milk intake on mental and motor development, intelligence quotient, and visual acuity compared with the feeding of formula. Human milk-fed infants also have decreased rates of rehospitalization after discharge. It is unclear how much human milk is needed to provide protection or at what postnatal age the protective effects maximize. The data suggest that a specific dose of milk may be needed to confer protection. A detailed composition analysis of milk obtained from women delivering before 30 weeks of gestation is needed to determine if the "immature" milk contains the same functional bioactive factors as more mature milk. Furthermore, lactation strategies should be sought that increase mother's own milk production.

    To determine whether severe retinopathy of prematurity (ROP) is associated with (1) abnormal white matter maturation and (2) neurodevelopmental outcomes at 18 months' corrected age (CA) compared with neonates without severe ROP. We conducted a prospective longitudinal cohort of extremely preterm neonates born 24-28 weeks' gestational age recruited between 2006 and 2013 with brain MRIs obtained both early in life and at term-equivalent age. Severe ROP was defined as ROP treated with retinal laser photocoagulation. Using diffusion tensor imaging and tract-based spatial statistics (TBSS), white matter maturation was assessed by mean fractional anisotropy (FA) in seven predefined regions of interest. Neurodevelopmental outcomes were assessed with Bayley Scales of Infant and Toddler Development-III (Bayley-III) composite scores at 18 months' CA. Subjects were compared using Fisher's exact, Kruskal-Wallis and generalised estimating equations. Families were recruited from the neonatal intensive care unit at BC Women's Hospital. Of 98 extremely preterm neonates (median: 26.0 weeks) assessed locally for ROP, 19 (19%) had severe ROP and 83 (85%) were assessed at 18 months' CA. Severe ROP was associated with lower FA in the posterior white matter, and with decreased measures of brain maturation in the optic radiations, posterior limb of the internal capsule (PLIC) and external capsule on TBSS. Bayley-III cognitive and motor scores were lower in infants with severe ROP. Severe ROP is associated with maturational delay in the optic radiations, PLIC, external capsule and posterior white matter, housing the primary visual and motor pathways, and is associated with poorer cognitive and motor outcomes at 18 months' CA. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    2010-09-01

    A growing and interdisciplinary translational neuroscience research effort for neurodevelopmental disorders (NDDs) is investigating the mechanisms of dysfunction and testing effective treatment strategies in animal models and, when possible, in the clinic. NDDs with a genetic basis have received particular attention. Transgenic animals that mimic genetic insults responsible for disease in man have provided insight about mechanisms of dysfunction, and, surprisingly, have shown that cognitive deficits can be addressed in adult animals. This review will present recent translational research based on animal models of genetic NDDs, as well as pharmacotherapeutic strategies under development to address deficits of brain function for Down syndrome, fragile X syndrome, Rett syndrome, neurofibromatosis-1, tuberous sclerosis, and autism. Although these disorders vary in underlying causes and clinical presentation, common pathways and mechanisms for dysfunction have been observed. These include abnormal gene dosage, imbalance among neurotransmitter systems, and deficits in the development, maintenance and plasticity of neuronal circuits. NDDs affect multiple brain systems and behaviors that may be amenable to drug therapies that target distinct deficits. A primary goal of translational research is to replace symptomatic and supportive drug therapies with pharmacotherapies based on a principled understanding of the causes of dysfunction. Based on this principle, several recently developed therapeutic strategies offer clear promise for clinical development in man.

    2009-01-01

    Premature birth is a growing and significant public health problem because of the large number of infants that survive with neurodevelopmental sequelae from brain injury. Recent advances in neuroimaging have shown that although some neuroanatomical structures are altered, others improve over time. This review outlines recent insights into brain structure and function in these preterm infants at school age and relevant animal models. These animal models have provided scientists with an opportunity to explore in depth the molecular and cellular mechanisms of injury as well as the potential of the brain for recovery. The endogenous potential that the brain has for neurogenesis and gliogenesis, and how environment contributes to recovery, are also outlined. These preclinical models will provide important insights into the genetic and epigenetic mechanisms responsible for variable degrees of injury and recovery, permitting the exploration of targeted therapies to facilitate recovery in the developing preterm brain.

    2012-09-01

    Autism is a neurodevelopmental disorder whose diagnosis is based on three behavioral criteria: unusual reciprocal social interactions, deficits in communication, and stereotyped repetitive behaviors with restricted interests. A large number of de novo single gene mutations and chromosomal deletions are associated with autism spectrum disorders. Based on the strong genetic evidence, mice with targeted mutations in homologous genes have been generated as translational research tools. Mouse models of autism have revealed behavioral and biological outcomes of mutations in risk genes. The field is now poised to employ the most robust phenotypes in the most replicable mouse models for preclinical screening of novel therapeutics.

    Full Text Available Abstract Background Approximately 30% of intubated preterm infants with respiratory distress syndrome (RDS will fail attempted extubation, requiring reintubation and mechanical ventilation. Although ventilator technology and monitoring of premature infants have improved over time, optimal extubation remains challenging. Furthermore, extubation decisions for premature infants require complex informational processing, techniques implicitly learned through clinical practice. Computer-aided decision-support tools would benefit inexperienced clinicians, especially during peak neonatal intensive care unit (NICU census. Methods A five-step procedure was developed to identify predictive variables. Clinical expert (CE thought processes comprised one model. Variables from that model were used to develop two mathematical models for the decision-support tool: an artificial neural network (ANN and a multivariate logistic regression model (MLR. The ranking of the variables in the three models was compared using the Wilcoxon Signed Rank Test. The best performing model was used in a web-based decision-support tool with a user interface implemented in Hypertext Markup Language (HTML and the mathematical model employing the ANN. Results CEs identified 51 potentially predictive variables for extubation decisions for an infant on mechanical ventilation. Comparisons of the three models showed a significant difference between the ANN and the CE (p = 0.0006. Of the original 51 potentially predictive variables, the 13 most predictive variables were used to develop an ANN as a web-based decision-tool. The ANN processes user-provided data and returns the prediction 0–1 score and a novelty index. The user then selects the most appropriate threshold for categorizing the prediction as a success or failure. Furthermore, the novelty index, indicating the similarity of the test case to the training case, allows the user to assess the confidence level of the prediction with

    Although antisocial personality disorder (APD) is one of the most researched personality disorders, it is still surprisingly resistant to treatment. This lack of clinical progress may be partly due to the failure to view APD as a neurodevelopmental disorder and to consider early interventions. After first defining what constitutes a neurodevelopmental disorder, this review evaluates the extent to which APD meets neurodevelopmental criteria, covering structural and functional brain imaging, neurocognition, genetics and epigenetics, neurochemistry, and early health risk factors. Prevention and intervention strategies for APD are then outlined, focusing on addressing early biological and health systems, followed by forensic and clinical implications. It is argued both that APD meets criteria for consideration as a neurodevelopmental disorder and that consideration should be given both to the possibility that early onset conduct disorder is neurodevelopmental in nature, and also to the inclusion of psychopathy as a specifier in future Diagnostic and Statistical Manual revisions of APD. Expected final online publication date for the Annual Review of Clinical Psychology Volume 14 is May 7, 2018. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

    Full Text Available GABAergic interneurons control neuronal excitability, integration, and plasticity. Further, they regulate the generation of temporal synchrony and oscillatory behavior among networks of pyramidal neurons. Such oscillations within and across neural systems are believed to serve various complex functions, such as perception, movement initiation, and memory. Alterations in the development of GABAergic circuits have been implicated in various brain diseases with neurodevelopmental origin. Here, we highlight recent studies suggesting a role for alterations of GABA transmission in the pathophysiology of two neurodevelopmental diseases, schizophrenia and autism. We further discuss how manipulations of GABA signaling may be used for novel therapeutic interventions.

    IUGR in humans is associated with impaired pre- and postnatal neurodevelopment, and subsequent postnatal cognition, resulting in lower IQ, poorer memory, visuomotor and executive function skills, as well as behavioural and attentional problems. Experimental models of IUGR are needed to allow direct testing of causality and interventions, and have benefits in reducing both confounding by comorbidities such as prematurity, and variation due to environment and genetics. This review describes and discusses experimental models of IUGR in which neurodevelopmental and cognitive outcomes of IUGR have been reported. We consider the timing of neurodevelopment relative to birth and to the period of restriction, as well as the effects of each experimental perturbation on the fetal environment and development, before discussing neurodevelopmental and cognitive outcomes for progeny as fetuses, neonates and into adolescent and adult life. Experimental IUGR induces broadly similar outcomes to human IUGR, with altered brain morphology, in particular grey matter loss and discordant trajectory of white matter development, and poorer cognition and memory reported in various studies. Nevertheless, there remain gaps in knowledge of neurodevelopment in experimental models. We end the review with recommendations for the design of future studies to further investigate the mechanisms underlying adverse neurodevelopmental consequences of IUGR, and to evaluate interventions that may subsequently improve outcomes of IUGR in humans.

    2015-10-01

    Management and decision whether to begin intensive care for very preterm infants below 26 WG and at borderline viability remains controversial, and survival rates for these children vary greatly and justify discussion with regards to literature data and according to the experience of others countries. If active management is more difficult with very preterm infants 24-25 WG, mortality is increased comparing with newborns of more than 26 WG. This is partly explained by limitations of active neonatal intensive care. Nevertheless, neurocomportemental and cognitive results are not so unfavorable. This justifies a human, medical, and ethical multidiciplinary discussion including the parents' wishes for an active resuscitation or a palliative management. Using the only criteria of gestational age is not a reliable tool to predict survival and neurodevelopmental outcome of preterm infants. It is very important to identify other prenatal factors such prenatal corticosteroid administration, gender, fetal estimated weight, amniotic fluid and absent/reverse end diastolic flow umbilical doppler. Implication and listening the parents' preferences are essential after individual information, objective and a honest counseling including mortality, morbidity and risks of neurocomportmental impairments. Birth and counseling should be done in reference maternofetal center with obstetricians and neonatalogist specialized in this topic. A real difficulty is to consider the route of delivery and the possibility that caesarean section could improve survival rates. Induction of labour is very often a high risk of failure and route of delivery remains controversial and this is a real question in order to improve survival rates. Literature is poor and conflicting without randomized trials. Caesarean section presents maternal risks such as pathologic placentation, haemorrhage delivery and increasing risks for the subsequent gestation. So, if it is not a good idea to recommend a systematic

    Dravet syndrome (DS) is an epilepsy of infantile onset, usually related to a mutation in gene sodium channel alpha 1 subunit, that leads to different typological seizures before the first year of life. Although most research has focused on the clinical description of the syndrome, some recent studies have focused on its impact on cognitive development, identifying both motor disorders and visual-processing deficits as basic factors affected in adults and children with DS. In this article, we designed a cross-sectional study to examine the cognitive phenotype of children affected by DS from a neurodevelopmental perspective. We report measures for both basic (auditory perception, visual and phonological processing, motor coordination) and higher order cognitive processes (verbal production, categorization, and executive function) in two age groups of DS children (M = 8.8 and M = 14.1) and control children of the same chronological age. Results showed an important cognitive delay in DS children with respect to controls in both basic and higher order cognitive abilities, with a better general outcome in tasks that required processing visual material (visual memory and categorization) than in tasks involving verbal material. In addition, performance of DS children in certain basic tasks (visual memory) correlated with performance on complex ones (categorization). These findings encourage promoting an early identification of not only clinical but also cognitive features in DS children from very early stages of development in order to optimize their neurodevelopmental outcome.

    Maximising response rates to neurodevelopmental follow-up is a key challenge for paediatric researchers. We have investigated the use of telephone interviews and online questionnaires to improve response rates, reduce non-response bias, maintain data completeness and produce unbiased outcomes compared with postal questionnaires when assessing neurodevelopmental outcomes at 2 years. A prospective cohort study of babies born ≥32 weeks gestation. Neurodevelopmental outcomes were assessed at 2 years of age using a parent questionnaire completed via post, telephone or online. Relative Risks with 95% confidence intervals (RR; 95% CI) were calculated to identify participant characteristics associated with non-response and questionnaire response mode (postal vs. telephone/online). The proportion of missing data and prevalence of adverse outcomes was compared between response modes using generalized linear models. Offering telephone/online questionnaires increased the study response rate from 55% to 60%. Telephone/online responders were more likely to be non-white (RR 1.6; [95% CI 1.1, 2.4]), non-English speaking (1.6; [1.0, 2.6]) or have a multiple birth (1.6; [1.1, 2.3]) than postal responders. There were no significant differences in the prevalence of adverse neurodevelopmental outcomes between those who responded via post vs. telephone/online (1.1; [0.9, 1.4]). Where parents attempted all questionnaire sections, there were no significant differences in the proportion of missing data between response modes. Where there is sufficient technology and resources, offering telephone interviews and online questionnaires can enhance response rates and improve sample representation to neurodevelopmental follow-up, whilst maintaining data completeness and unbiased outcomes.

    Children born to women with systemic lupus erythematosus seem to have a potentially increased risk of neurodevelopmental disorders compared to children born to healthy women. Recent experimental data suggest in utero exposure to maternal antibodies and cytokines as important risk factors for neurodevelopmental disorders. Interestingly, women with systemic lupus erythematosus display high levels of autoantibodies and cytokines, which have been shown, in animal models, to alter fetal brain development and induce behavioral anomalies in offspring. Furthermore, subjects with systemic lupus erythematosus and neurodevelopmental disorders share a common genetic predisposition, which could impair the fetal immune response to in utero immunologic insults. Moreover, systemic lupus erythematosus pregnancies are at increased risk of adverse obstetrical outcomes and medication exposures, which have been implicated as potential risk factors for neurodevelopmental disorders. In this article, we review the current state of knowledge on neurodevelopmental disorders and their potential determinants in systemic lupus erythematosus offspring. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Premature ejaculation, also referred to as rapid or early ejaculation, is a poorly understood disorder with no single, widely-recognised, evidence-based definition. Studies based on patient self-reporting indicate that premature ejaculation is a common complaint with estimated prevalence ranging from 4%-39% of men in the general community.(1) However, a lack of an accurate validated definition has made comparison of the results of such studies difficult.(2) In addition, perception of normal ejaculatory latency varies by country and differs when assessed by the patient or their partner.(3) ▾Dapoxetine (Priligy-A. Menarini Farmaceutica Internazionale SRL), a short-acting selective serotonin reuptake inhibitor (SSRI) is the first drug to be licensed in the UK for on-demand management of diagnosed premature ejaculation.(4) In this article we review the evidence for dapoxetine and discuss some of the challenges associated with its introduction.

  17. Autoimmune premature ovarian failure

    Directory of Open Access Journals (Sweden)

    Beata Komorowska

    2017-02-01

    Full Text Available 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.

  18. The cerebellum and neurodevelopmental disorders

    2015-01-01

    Cerebellar dysfunction is evident in several developmental disorders, including autism, attention deficit hyperactivity disorder (ADHD), and developmental dyslexia, and damage to the cerebellum early in development can have long-term effects on movement, cognition, and affective regulation. Early cerebellar damage is often associated with poorer outcomes than cerebellar damage in adulthood, suggesting that the cerebellum is particularly important during development. Differences in cerebellar development and/or early cerebellar damage could impact a wide range of behaviors via the closed-loop circuits connecting the cerebellum with multiple cerebral cortical regions. Based on these anatomical circuits, behavioral outcomes should depend on which cerebro-cerebellar circuits are affected. Here, we briefly review cerebellar structural and functional differences in autism, ADHD, and developmental dyslexia, and discuss clinical outcomes following pediatric cerebellar damage. These data confirm the prediction that abnormalities in different cerebellar subregions produce behavioral symptoms related to the functional disruption of specific cerebro-cerebellar circuits. These circuits might also be crucial to structural brain development, as peri-natal cerebellar lesions have been associated with impaired growth of the contralateral cerebral cortex. The specific contribution of the cerebellum to typical development may therefore involve the optimization of both the structure and function of cerebro-cerebellar circuits underlying skill acquisition in multiple domains; when this process is disrupted, particularly in early development, there could be long-term alterations of these neural circuits, with significant impacts on behavior.

    Full Text Available Abstract 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 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.

    Prenatal exposure to organophosphorus pesticides (OPs) has been associated with different neurodevelopmental outcomes across different cohorts. A phenotypic approach may address some of these differences by incorporating information across scales and accounting for the complex correlational structure of neurodevelopmental outcomes. Additionally, Bayesian hierarchical modeling can account for confounding by collinear co-exposures. We use this framework to examine associations between prenatal exposure to OPs and behavior, executive functioning, and IQ assessed at age 6-9 years in a cohort of 404 mother/infant pairs recruited during pregnancy. We derived phenotypes of neurodevelopment with a factor analysis, and estimated associations between OP metabolites and these phenotypes in Bayesian hierarchical models for exposure mixtures. We report seven factors: 1) Impulsivity and Externalizing, 2) Executive Functioning, 3) Internalizing, 4) Perceptual Reasoning, 5) Adaptability, 6) Processing Speed, and 7) Verbal Intelligence. These, along with the Working Memory Index, were standardized and scaled so that positive values reflected positive attributes and negative values represented adverse outcomes. Standardized dimethylphosphate metabolites were negatively associated with Internalizing factor scores (β^ - 0.13, 95% CI - 0.26, 0.00) but positively associated with Executive Functioning factor scores (β^ 0.18, 95% CI 0.04, 0.31). Standardized diethylphosphate metabolites were negatively associated with the Working Memory Index (β^ - 0.17, 95% CI - 0.33, - 0.03). Associations with factor scores were generally stronger and more precise than associations with individual instrument-specific items. Factor analysis of outcomes may provide some advantages in etiological studies of childhood neurodevelopment by incorporating information across scales to reduce dimensionality and improve precision.

    Full Text Available BACKGROUND: The objective of this study was to determine whether acute histologic chorioamnionitis is associated with adverse neonatal outcomes in late preterm infants who were born after preterm PROM. METHODOLOGY/PRINCIPAL FINDINGS: The relationship between the presence of acute histologic chorioamnionitis and adverse neonatal outcome was examined in patients with preterm PROM who delivered singleton preterm newborns between 34 weeks and 36 6/7 weeks of gestation. Nonparametric statistics were used for data analysis. The frequency of acute histologic chorioamnionitis was 24% in patients with preterm PROM who delivered preterm newborns between 34 weeks and 36 6/7 weeks of gestation. Newborns born to mothers with histologic chorioamnionitis had significantly higher rates of adverse neonatal outcome (74% vs 51%; p<0.005 than those without histologic chorioamnionitis. This relationship remained significant after adjustment for gestational age at preterm PROM, gestational age at delivery, and exposure to antenatal corticosteroids. CONCLUSIONS/SIGNIFICANCE: The presence of acute histologic chorioamnionitis is associated with adverse neonatal outcome in late preterm infants born to mothers with preterm PROM.

    Preterm children have problems with mathematics but knowledge about the predictors of specific mathematic abilities in preterm populations is scarce. This study investigated neurodevelopmental pathways to children's general and specific mathematic abilities across the full gestational age range. Prospective geographically defined longitudinal investigation in Germany. 947 children across the full gestational age range (23-41 weeks). Outcome measures. At 8 years, children's cognitive and mathematic abilities were measured and residuals of a regression predicting mathematic scores by IQ were used to identify specific mathematic abilities. Neurodevelopmental cascade models revealed that adverse effects of preterm birth on mathematic abilities were mediated by neonatal risk. Specific mathematic abilities were uniquely predicted by the duration of hospitalization and ventilation. Prolonged neonatal medical treatment and, in particular, mechanical ventilation may lead to specific impairments in mathematic tasks. These findings have implications for the mode of respiratory support in neonates, routine follow-up and intervention planning as well as research about brain reorganization after preterm birth.

  6. Academic underachievement: A neurodevelopmental perspective

    Directory of Open Access Journals (Sweden)

    K. Shapiro Bruce, MD

    2011-03-01

    Full Text Available Academic underachievement is a common presenting symptom and has many different causes. The disorders that describe academic underachievement are based on the child’s function in cognitive, academic, or behavioral domains. The disorders that are associated with academic underachievement are final common pathways that have different etiologies and mechanisms. Multiple disorders are the rule because brain dysfunction in childhood usually affects multiple functions. Consequently, management programs must be individualized, comprehensive and address issues related to the child, school, and family. Treatment plans include parent training, academic accommodations, techniques to maintain self-esteem, and psychopharmacologic approaches. Ongoing monitoring of the management programs is necessary to detect important comorbidities that may emerge, to modify the program to meet the changing academic and social demands that occur as the child ages, and to provide current information. The outcome for children with academic underachievement is most dependent on the underlying disorder. Health providers have multiple roles to play in the prevention, detection, diagnosis and management of children with academic underachievement.

  7. Histone Lysine Methylation and Neurodevelopmental Disorders

    Full Text Available Methylation of several lysine residues of histones is a crucial mechanism for relatively long-term regulation of genomic activity. Recent molecular biological studies have demonstrated that the function of histone methylation is more diverse and complex than previously thought. Moreover, studies using newly available genomics techniques, such as exome sequencing, have identified an increasing number of histone lysine methylation-related genes as intellectual disability-associated genes, which highlights the importance of accurate control of histone methylation during neurogenesis. However, given the functional diversity and complexity of histone methylation within the cell, the study of the molecular basis of histone methylation-related neurodevelopmental disorders is currently still in its infancy. Here, we review the latest studies that revealed the pathological implications of alterations in histone methylation status in the context of various neurodevelopmental disorders and propose possible therapeutic application of epigenetic compounds regulating histone methylation status for the treatment of these diseases.

    Infants born with tuberous sclerosis complex, a genetic condition resulting from a mutation in TSC1 or TSC2, are at increased risk for intellectual disability and/or autism. Features of epilepsy, neuropathology, genetics, as well as timing and type of mechanism-based medications have been proposed as risk factors. Neurodevelopmental outcomes have been reported among these studies; however, few include data about the individuals' early neurodevelopmental profile, a factor that may contribute significantly to these outcomes. Further, there is no clinical standard for the neurodevelopmental assessment of these infants. The paucity of data regarding the natural history of neurodevelopment in infants with tuberous sclerosis complex and the lack of a gold standard for neurodevelopmental evaluation present a significant challenge for clinicians and researchers. During the first year of life, we tracked the onset of infantile spasms, the type and timing of antiepileptic treatments, and the associated response of two age-matched infants with tuberous sclerosis complex. We also employed Capute Scales as a part of a structured neurodevelopmental evaluation to characterize and compare their neurodevelopmental profiles. Infant 1 developed infantile spasms with confirmed hypsarrhythmia at 4 months of age. Treatment with vigabatrin was initiated within 24 hours with near immediate cessation of seizures and no further seizures to date. Expressive language delay was detected at 12 months and treated with speech and/or language therapy. Infant 2 developed complex partial seizures at 1 month. Treatment included levetiracetam, oxcarbazepine, and the ketogenic diet. Vigabatrin was initiated on detection of hypsarrhythmia after 4 months. Intractable epilepsy persists to date. Global developmental delay was evident by 8 months and treated with physical, occupational, and speech and/or language therapy. Many risk factors have been associated with intellectual disability and/or autism in

    Objective To determine if improvements in cognitive outcome detected at 18 months’ corrected age (CA) in infants born DHA) compared with standard-DHA diet were sustained in early childhood. Design Follow-up of a multicentre randomised controlled trial. Randomisation was stratified for sex, birth weight (DHA (≈1% total fatty acids) enteral feeds compared with standard-DHA (≈0.3% total fatty acids) from age 2–4 days until term CA. Primary outcome Full Scale IQ of the Wechsler Abbreviated Scale of Intelligence (WASI) at 7 years CA. Prespecified subgroup analyses based on the randomisation strata (sex, birth weight) were conducted. Results 604 (92% of the 657 originally randomised) consented to participate (291 high-DHA, 313 standard-DHA). To address missing data in the 604 consenting participants (22 for primary outcome), multiple imputation was performed. The Full Scale IQ was not significantly different between groups (high-DHA 98.3, SD 14.0, standard-DHA 98.5, SD 14.9; mean difference adjusted for sex, birthweight strata and hospital −0.3, 95% CI −2.9 to 2.2; p=0.79). There were no significant differences in any secondary outcomes. In prespecified subgroup analyses, there was a significant sex by treatment interaction on measures of parent-reported executive function and behaviour. Scores were within the normal range but girls receiving the high-DHA diet scored significantly higher (poorer outcome) compared with girls receiving the standard-DHA diet. Conclusions Supplementing the diets of preterm infants with a DHA dose of approximately 1% total fatty acids from days 2–4 until term CA showed no evidence of benefit at 7 years’ CA.

    To study the effects of postnatal growth retardation on early neurodevelopment in premature infants with intrauterine growth retardation (IUGR). A retrospective analysis was performed on the clinical data of 171 premature infants who were born between May 2008 and May 2012 and were followed up until a corrected gestational age of 6 months. These infants were classified into two groups: IUGR group (n=40) and appropriate for gestational age (AGA) group (n=131). The growth retardation rates at the corrected gestational ages of 40 weeks, 3 months, and 6 months, as well as the neurodevelopmental outcome (evaluated by Gesell Developmental Scale) at corrected gestational ages of 3 and 6 months, were compared between the two groups. The growth retardation rate in the IUGR group was significantly higher than in the AGA group at the corrected gestational ages of 40 weeks, 3 months, and 6 months. All five developmental quotients evaluated by Gesell Developmental Scale (gross motor, fine motor, language, adaptability and individuality) in the IUGR group were significantly lower than in the AGA group at the corrected gestational ages of 3 months. At the corrected gestational age of 6 months, the developmental quotients of fine motor and language in the IUGR group were significantly lower than in the AGA group, however, there were no significant differences in the developmental quotients of gross motor, adaptability and individuality between the two groups. All five developmental quotients in IUGR infants with catch-up lag in weight were significantly lower than in IUGR and AGA infants who had caught up well. Growth retardation at early postnatal stages may adversely affect the early neurodevelopment in infants with IUGR.

    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...

    Premature graying is an important cause of low self-esteem, often interfering with socio-cultural adjustment. The onset and progression of graying or canities correlate very closely with chronological aging, and occur in varying degrees in all individuals eventually, regardless of gender or race. Premature canities may occur alone as an autosomal dominant condition or in association with various autoimmune or premature aging syndromes. It needs to be differentiated from various genetic hypomelanotic hair disorders. Reduction in melanogenically active melanocytes in the hair bulb of gray anagen hair follicles with resultant pigment loss is central to the pathogenesis of graying. Defective melanosomal transfers to cortical keratinocytes and melanin incontinence due to melanocyte degeneration are also believed to contribute to this. The white color of canities is an optical effect; the reflection of incident light masks the intrinsic pale yellow color of hair keratin. Full range of color from normal to white can be seen both along individual hair and from hair to hair, and admixture of pigmented and white hair is believed to give the appearance of gray. Graying of hair is usually progressive and permanent, but there are occasional reports of spontaneous repigmentation of gray hair. Studies evaluating the association of canities with osteopenia and cardiovascular disease have revealed mixed results. Despite the extensive molecular research being carried out to understand the pathogenesis of canities, there is paucity of effective evidence-based treatment options. Reports of repigmentation of previously white hair following certain inflammatory processes and use of drugs have suggested the possibility of cytokine-induced recruitment of outer sheath melanocytes to the hair bulb and rekindled the hope for finding an effective drug for treatment of premature canities. In the end, camouflage techniques using hair colorants are outlined.

    Many studies have investigated the neurodevelopmental effects of prenatal and early childhood exposures to organophosphate (OP) pesticides among children, but they have not been collectively evaluated. The aim of the present article is to synthesize reported evidence over the last decade on OP exposure and neurodevelopmental effects in children. The Data Sources were PubMed, Web of Science, EBSCO, SciVerse Scopus, SpringerLink, SciELO and DOAJ. The eligibility criteria considered were studies assessing exposure to OP pesticides and neurodevelopmental effects in children from birth to 18 years of age, published between 2002 and 2012 in English or Spanish. Twenty-seven articles met the eligibility criteria. Studies were rated for evidential consideration as high, intermediate, or low based upon the study design, number of participants, exposure measurement, and neurodevelopmental measures. All but one of the 27 studies evaluated showed some negative effects of pesticides on neurobehavioral development. A positive dose–response relationship between OP exposure and neurodevelopmental outcomes was found in all but one of the 12 studies that assessed dose–response. In the ten longitudinal studies that assessed prenatal exposure to OPs, cognitive deficits (related to working memory) were found in children at age 7 years, behavioral deficits (related to attention) seen mainly in toddlers, and motor deficits (abnormal reflexes) seen mainly in neonates. No meta-analysis was possible due to different measurements of exposure assessment and outcomes. Eleven studies (all longitudinal) were rated high, 14 studies were rated intermediate, and two studies were rated low. Evidence of neurological deficits associated with exposure to OP pesticides in children is growing. The studies reviewed collectively support the hypothesis that exposure to OP pesticides induces neurotoxic effects. Further research is needed to understand effects associated with exposure in critical windows

  15. Severe influenza among children and young adults with neurologic and neurodevelopmental conditions - Ohio, 2011.

    Science.gov (United States)

    2012-01-06

    Children with neurologic and neurodevelopmental conditions are at increased risk for severe outcomes from influenza, including death. In April 2011, the Ohio Department of Health and CDC investigated an influenza outbreak that began in February 2011 in a residential facility for 130 children and young adults with neurologic and neurodevelopmental conditions. This report summarizes the characteristics and clinical courses of 13 severely ill residents with suspected or confirmed influenza; 10 were hospitalized, and seven died. Diagnosis is challenging in this population, and clinicians should consider influenza in patients with neurologic and neurodevelopmental conditions who have respiratory illness or a decline in baseline medical status when influenza is circulating in the community. Prompt testing, early and aggressive antiviral treatment, and antiviral chemoprophylaxis are important for these patients. When influenza is suspected, antiviral treatment should be given as soon as possible after symptom onset, ideally within 48 hours. Treatment should not wait for laboratory confirmation of influenza. During outbreaks, antiviral chemoprophylaxis should be provided to all residents of institutional facilities (e.g., nursing homes and long-term- care facilities), regardless of vaccination status. Residential facilities for patients with neurologic and neurodevelopmental conditions are encouraged to vaccinate all eligible residents and staff members against influenza.

    Heritable neurodevelopmental disorders are multifaceted disease conditions encompassing a wide range of symptoms including intellectual disability, cognitive dysfunction, autism and myriad other behavioral impairments. In cases where single, causative genetic defects have been identified, such as Angelman syndrome, Rett syndrome, Neurofibromatosis Type 1 and Fragile X syndrome, the classical Drosophila genetic system has provided fruitful disease models. Recent Drosophila studies have advanced our understanding of UBE3A, MECP2, NF1 and FMR1 function, respectively, in genetic, biochemical, anatomical, physiological and behavioral contexts. Investigations in Drosophila continue to provide the essential mechanistic understanding required to facilitate the conception of rational therapeutic treatments. Copyright © 2011 Elsevier Ltd.

    Full Text Available Prematurity and, as a result, the expressed morphofunctional immaturity of all body organs and systems makes an essential contribution to morbidity and mortality rates. The efficiency of care for prematurely born children in many respects depends on adequacy of the enteral and parenteral nutrition program. The balanced and correctly organized nutrition is one of the most important components of care for the prematurely born children, which defines both immediate and remote prognosis. The review of literature on parenteral nutrition in prematurely born children is given. The main indications, dosages, beginning time, and strategies for the appointment of «aggressive» nutrition are specified. Main conclusion: it is necessary to use higher doses for parenteral nutrition, and take into account that an early appointment of amino acids and fatty emulsions is important. An early ‘aggressive’ nutrition strategy is well tolerated by preterm infants and provides proper rates of physical development in the postnatal period without adverse outcomes

    Abstract Approximately 15% of preterm infants may develop postnatal cytomegalovirus (CMV) infection from seropositive mothers via breast milk and are at risk for neurological sequelae in childhood. The aims of this study were to assess the effects and outcomes on growth, neurodevelopmental status, and hearing in very low birth weight (VLBW) premature infants with postnatal CMV infection via breast milk at the corrected age of 12 and 24 months. The prospective follow-up study population comprised all living preterm children (n = 55) with a birth weight ≤1500 g and gestational age of ≤35 weeks, who had been participated in our “postnatal CMV infection via breast milk” studies in 2000 and 2009, respectively. The cohort of children was assessed at 12 and 24 months. Clinical outcomes were documented during hospitalization and after discharge. Long-term outcomes included anthropometry, audiologic tests, gross motor quotient, Infant International Battery, and neurodevelopmental outcomes; all were assessed at postcorrected age in 12 and 24 months during follow-up visits. Of the 55 infants enrolled in the study (4 noninfected infants were excluded because their parents did not join this follow-up program later), 14 infants postnatally acquired CMV infection through breast-feeding (infected group) and were compared with 41 infants without CMV infection (control group). No significant differences were observed between the groups with regard to baseline characteristics, clinical outcomes, anthropometry, or psychomotor and mental development on the Bayley scale of infant development. None of the infants had CMV-related death or permanent sensorineural hearing loss. Transmission of CMV from seropositive mother via breast milk to preterm infants does not appear at this time to have major adverse effects on clinical outcomes, growth, neurodevelopmental status, and hearing function at 12 and 24 months corrected age.

    Schizophrenia is a complex disorder of unknown origin, characterised by abnormalities in the realms of perception, thinking and the experience of emotions that onset is restricted to young adulthood. Many techniques that range from neuropathology to neuroimaging identified subtle brain abnormalities particularly in frontal, temporal cortex, hippocampus, basal ganglia and cerebellum. Neurodevelopmental models of schizophrenia test hypotheses that this disease is caused by a defect in cerebral development which results in altered neural connectivity, brain neurochemistry and aberrant behaviour observed in adult life. Recent evidence indicates that neonatal hippocampal damage may affect prefrontal neuronal integrity. The developmental lesion model appears to have predictive validity because treatment with antipsychotic drugs normalises some abnormal behaviour changes. Therefore it will be a useful paradigm in the work on new therapies and in providing new insights about pathophysiology and etiology of schizophrenia.

    This review describes recent research in pediatric sleep disorders associated with neurodevelopmental disabilities (NDDs) and their treatment. NDDs affect more than 2% of the general population and represent more than 35% of the total cases of children referred to a neuropsychiatric center for sleep problems. Specific clinical and therapeutic aspects of sleep disorders associated with Down syndrome, Fragile X syndrome, Prader-Willi syndrome, Angelman syndrome, Rett syndrome, Smith-Magenis syndrome, cerebral palsy, and autism spectrum disorders are described. Furthermore, the drugs commonly used for sleep disorders in children with NDDs are described. The review clearly highlighted that children with NDDs are often affected by sleep disorders that require appropriate clinical and therapeutic approach to improve quality of life in both patients and families.

    Autism is a developmental disorder with variable severity, occurring at all levels of cognitive ability and having a number of slightly different clinical presentations. It is associated with neuropsychological deficits that occur in other conditions also, but its pattern may be specific to autism. Genetic and environmental early insults to brain development are etiological determinants of the disorder. Brain circuitries important for social, communicative, and integrational purposes have been suggested to be dysfunctional in autism. There could be at least two different pathways to autism, one connected with primary temporofrontal dysfunction (and late prenatal-early postnatal origins) and another linked to primary brain-stem dysfunction (and early prenatal origins). Further study of neurodevelopmental and neuropsychological processes in autism will help elucidate not only the pathological mechanisms involved in the specific syndromes but also the underpinnings of normal brain development.

  4. Complex Neurodevelopmental Disorders And Their Genetic Etiologies

    Amna Batool

    2015-08-01

    Full Text Available Complex Neurodevelopmental disorders NDDs exhibit complex etiological and genetic features and the mutations have a fundamental role in this complexity including common polymorphisms and rare variations in a single gene or cluster of genes. The analysis of complex NDDs have shown that the genetics has the major role in causation of such complex diseases. Interestingly both mutations and polymorphisms are involved occurring in a single gene or clusters of genes. Likewise a single gene variation may also be involved in multiple neurological disorders making the diagnosis of neurological diseases more difficult. Many candidate genes and chromosomal regions have been identified that are widely involved in neurological symptoms which necessitates the genotypic approach for describing the phenotype.

    The main aims of this paper are to review and evaluate the neurobiology of the depressive syndrome from a neurodevelopmental perspective. An English language literature search was performed using PubMed. Depression is a complex syndrome that involves anatomical and functional changes that have an early origin in brain development. In subjects with genetic risk for depression, early stress factors are able to mediate not only the genetic risk but also gene expression. There is evidence that endocrine and immune interactions have an important impact on monoamine function and that the altered monoamine signalling observed in the depressive syndrome has a neuro-endocrino-immunological origin early in the development. Neurodevelopment is a key aspect to understand the whole neurobiology of depression.

    .007.Depressed neonatal aEEG patterns are associated with placental lesions consistent with maternal under perfusion, and amniotic fluid infection of fetal type, but not with fetal thrombo-oclusive vascular disease of inflammatory type. Our findings highlight the association between the intrauterine mechanisms leading to preterm parturition and subsequent depressed neonatal cerebral function early after birth, which eventually may put premature infants at risk for abnormal neurodevelopmental outcome.

  8. Increased risk of neuropsychological disorders in children born preterm without major disabilities: a neurodevelopmental model

    2009-06-01

    Full Text Available Over the past 30 years, preterm births have drastically increased and today represent 12.5% of total births. About 1.2% of preterm births characterize very preterm births (GA<32weeks that, with very low birth weight (BW<1500grams, are constantly found as risk factors of unfavourable neurological outcomes in longitudinal follow up studies. Actually, also “late preterm” children (preterm born from 33 to 36 weeks of gestational age, normally considered at low risk for neurodevelopmental disabilities, are supposed to represent a population of children to be monitored. Previous findings of a general cognitive impairment in children born preterm have gradually addressed the assessment of more specific neuropsychological skills and pointed out the importance to follow these children up to adolescent age. The neuroanatomical prerequisite of an abnormality in frontal lobe development and the correlation with various neuropsychological dysfunctions (fine and gross motor disabilities, executive function and working memory deficits, visual-constructional and attentional dysfunctions underline the interference of preterm birth with normal brain maturational phases. Though showing more demanding neurodevelopmental pathways than term peers, a large number of preterm children tend to functionally normalize in adolescence. The review supports the hypothesis of a neurodevelopmental model that can be at risk to influence dysfunctional neuropsychological outcome.

    Neurodevelopmental outcomes including behavior, executive functioning, and IQ exhibit complex correlational structures, although they are often treated as independent in etiologic studies. We performed a principal components analysis of the behavioral assessment system for children, the behavior rating inventory of executive functioning, and the Wechsler scales of intelligence in a prospective birth cohort, and estimated associations with early life characteristics. We identified seven factors: (1) impulsivity and externalizing, (2) executive functioning, (3) internalizing, (4) perceptual reasoning, (5) adaptability, (6) processing speed, and (7) verbal intelligence. Prenatal fish consumption, maternal education, preterm birth, and the home environment were important predictors of various neurodevelopmental factors. Although maternal smoking was associated with more adverse externalizing, executive functioning, and adaptive composite scores in our sample, of the orthogonally-rotated factors, smoking was only associated with the impulsivity and externalizing factor ([Formula: see text] - 0.82, 95% CI - 1.42, - 0.23). These differences may be due to correlations among outcomes that were accounted for by using a phenotypic approach. Dimension reduction may improve upon traditional approaches by accounting for correlations among neurodevelopmental traits.

    Careful study of the phenotype can have implications at several levels, namely clinical diagnosis, pathophysiological reasoning, management planning, and outcome measurement. Behavioural phenotypes involve cognition, communication, social skills, and motor control. They can be documented in a host of neurodevelopmental conditions and approached with the recently refined perception-action-cognition-environment (PACE) paradigm, which focuses on the neurodevelopmental processes that underlie learning and adaption to the environment through perception, action, and cognitive processing. Although this paradigm was originally developed in the context of cerebral palsy, it can be applied along developmental trajectories in several neurogenetic conditions, including Down syndrome, fragile X syndrome, Rett syndrome, Angelman syndrome, and Williams syndrome, to name but a few. It must be recognized, however, that relevant, valid tools for assessment and management strategies still need to be developed. © 2015 The Authors.

    HIV infection in infancy may influence the developing brain, leading to adverse neurodevelopmental consequences. We aim to describe neurodevelopmental characteristics of a cohort of HIV-infected infants and young children prior to antiretroviral therapy (ART) initiation and after achieving viral suppression. As part of the Neverest 2 trial, 195 HIV-infected children under 2 years of age were assessed using the Ages and Stages Questionnaire (ASQ) prior to ART initiation and at subsequent age-appropriate time points after ART had been started. The ASQ is a simple screening questionnaire used to identify children at risk of neurodevelopmental delays. Questionnaires completed by the parent/caregiver assess neurodevelopmental functioning in five domains: communication, gross motor, fine motor, problem solving and personal-social. Median age pre-ART was 8.8 months (range 2.2-24.9) and 53.9% were male. Mean time to viral suppression was 9.4 months (range 5.9-14.5). Compared with pre-ART better outcomes were reported at time of viral suppression with a lower proportion of children failing the gross motor (31.5% vs. 13%, p = 0.0002), fine motor (21.3% vs. 10.2%, p = 0.017), problem solving (26.9% vs. 9.3%, p = 0.0003) and personal-social (19.6% vs. 7.4%, p = 0.019) domains. However, there was no change in the communication domain (14.8% vs. 12.0%, p = 0.6072). Although achieving viral suppression on ART resulted in significant improvements in markers of neurodevelopmental function of young HIV-infected children, potential neurodevelopmental delays still persisted in a large proportion. Further interventions are needed to limit potential disabilities and maximize developmental outcomes. © 2016 John Wiley & Sons Ltd.

  13. The Impact of Kangaroo Care on Premature Infant Weight Gain.

    Evereklian, Melvina; Posmontier, Bobbie

    Preterm births occur among 11.4% of all live infant births. Without steady weight gain, premature infants may experience lengthy hospitalizations, neurodevelopmental deficits and hospital readmissions, which can increase the financial burden on the health care system and their families. The total U.S. health-related costs linked to preterm infant deliveries are estimated at $4.33 billion. Kangaroo care is a feasible practice that can improve preterm infant weight gain. However, this intervention is utilized less often throughout the U.S. due to numerous barriers including a lack of consistent protocols, inadequate knowledge, and decreased level of confidence in demonstrating the proper kangarooing technique. An integrative review was conducted to evaluate the impact of kangaroo care on premature infant weight gain in order to educate nurses about its efficacy among preterm infants. A literature search was conducted using CINAHL, PubMed, Cochrane Reviews, ClinicalKey and Google Scholar. Large volume searches were restricted using appropriate filters and limiters. Most of the evaluated studies determined that weight gain was greater among the kangarooing premature infants. Kangaroo care is a low-tech low-cost modality that can facilitate improved preterm infant weight gain even in low-resource settings. Despite its current efficacy, kangaroo care is not widely utilized due to several barriers including an absence of standardized protocols and a lack of knowledge about its benefits. Kangaroo care can become a widespread formalized practice after nurses and parents learn about the technique and its numerous benefits for premature infants, including its association with improved weight gain.

    1996-04-01

    To give an overall appraisal of the clinical features of Down syndrome (DS) in Chinese children with emphasis on the neurodevelopmental outcome, and to compare the related complications with that of other races. The records of 124 Chinese children with DS assessed at the Child Assessment Centre of the University Department of Paediatrics in the Duchess of Kent Children's Hospital from 1985 to 1993 were reviewed. Thirty-one per cent of patients had microcephaly. Eighty-five percent (33/39) when assessed in the first year of life had a developmental quotient (DQ) above 50 but only 29% (2/7) had DQ above 50 when assessed after the age of 5. Only two patients (1.6%) had epilepsy: infantile spasms (1) and Lennox-Gastaut syndrome (1). Hearing impairment was found in 45% of children with mild conductive hearing impairment being the most common. Chinese children with DS, when compared with other races, were similarly intellectually disabled, but were less likely to develop epilepsy.

    Full Text Available Humans evolved within a microbial ecosystem resulting in an interlinked physiology. The gut microbiota can signal to the brain via the immune system, the vagus nerve or other host-microbe interactions facilitated by gut hormones, regulation of tryptophan metabolism and microbial metabolites such as short chain fatty acids (SCFA, to influence brain development, function and behavior. Emerging evidence suggests that the gut microbiota may play a role in shaping cognitive networks encompassing emotional and social domains in neurodevelopmental disorders. Drawing upon pre-clinical and clinical evidence, we review the potential role of the gut microbiota in the origins and development of social and emotional domains related to Autism spectrum disorders (ASD and schizophrenia. Small preliminary clinical studies have demonstrated gut microbiota alterations in both ASD and schizophrenia compared to healthy controls. However, we await the further development of mechanistic insights, together with large scale longitudinal clinical trials, that encompass a systems level dimensional approach, to investigate whether promising pre-clinical and initial clinical findings lead to clinical relevance.

    There are substantial differences in the amount of research concerned with different disorders. This paper considers why. Bibliographic searches were conducted to identify publications (1985-2009) concerned with 35 neurodevelopmental disorders: Developmental dyslexia, Developmental dyscalculia, Developmental coordination disorder, Speech sound disorder, Specific language impairment, Attention deficit hyperactivity disorder, Autistic spectrum disorder, Tourette syndrome, Intellectual disability, Angelman syndrome, Cerebral palsy, Cornelia de Lange syndrome, Cri du chat syndrome, Down syndrome, Duchenne muscular dystrophy, Fetal alcohol syndrome, Fragile X syndrome, Galactosaemia, Klinefelter syndrome, Lesch-Nyhan syndrome, Lowe syndrome, Marfan syndrome, Neurofibromatosis type 1, Noonan syndrome, Phenylketonuria, Prader-Willi syndrome, Rett syndrome, Rubinstein-Taybi syndrome, Trisomy 18, Tuberous sclerosis, Turner syndrome, Velocardiofacial syndrome, Williams syndrome, XXX and XYY. A publication index reflecting N publications relative to prevalence was derived. The publication index was higher for rare than common conditions. However, this was partly explained by the tendency for rare disorders to be more severe. Although research activity is predictable from severity and prevalence, there are exceptions. Low rates of research, and relatively low levels of NIH funding, characterise conditions that are the domain of a single discipline with limited research resources. Growth in research is not explained by severity, and was exceptionally steep for autism and ADHD.

    2012-05-01

    Math anxiety is a negative emotional reaction to situations involving mathematical problem solving. Math anxiety has a detrimental impact on an individual's long-term professional success, but its neurodevelopmental origins are unknown. In a functional MRI study on 7- to 9-year-old children, we showed that math anxiety was associated with hyperactivity in right amygdala regions that are important for processing negative emotions. In addition, we found that math anxiety was associated with reduced activity in posterior parietal and dorsolateral prefrontal cortex regions involved in mathematical reasoning. Multivariate classification analysis revealed distinct multivoxel activity patterns, which were independent of overall activation levels in the right amygdala. Furthermore, effective connectivity between the amygdala and ventromedial prefrontal cortex regions that regulate negative emotions was elevated in children with math anxiety. These effects were specific to math anxiety and unrelated to general anxiety, intelligence, working memory, or reading ability. Our study identified the neural correlates of math anxiety for the first time, and our findings have significant implications for its early identification and treatment.

  2. Models of Neurodevelopmental Abnormalities in Schizophrenia

    Powell, Susan B.

    2013-01-01

    The neurodevelopmental hypothesis of schizophrenia asserts that the underlying pathology of schizophrenia has its roots in brain development and that these brain abnormalities do not manifest themselves until adolescence or early adulthood. Animal models based on developmental manipulations have provided insight into the vulnerability of the developing fetus and the importance of the early environment for normal maturation. These models have provided a wide range of validated approaches to answer questions regarding environmental influences on both neural and behavioral development. In an effort to better understand the developmental hypothesis of schizophrenia, animal models have been developed, which seek to model the etiology and/or the pathophysiology of schizophrenia or specific behaviors associated with the disease. Developmental models specific to schizophrenia have focused on epidemiological risk factors (e.g., prenatal viral insult, birth complications) or more heuristic models aimed at understanding the developmental neuropathology of the disease (e.g., ventral hippocampal lesions). The combined approach of behavioral and neuroanatomical evaluation of these models strengthens their utility in improving our understanding of the pathophysiology of schizophrenia and developing new treatment strategies.

    To determine whether the benefits of caffeine vary in three subgroups of 2006 participants in the Caffeine for Apnea of Prematurity (CAP) trial. Post-hoc subgroup analyses were performed on the basis of: (1) indication for commencement of study drug: treat apnea, prevent apnea, or facilitate extubation; (2) positive pressure ventilation (PPV) at randomization: endotracheal tube (ETT), noninvasive ventilation, or none; and (3) timing of commencement of study drug: early or late (3 days). Outcomes assessed were those showing treatment effects in the original analyses. We investigated the consistency of caffeine effects by using regression models that incorporated treatment/subgroup factor interactions. There was little evidence of a differential treatment effect of caffeine in subgroups defined by the clinical indication for starting study drug. The size and direction of the caffeine effect on death or disability differed depending on PPV at randomization (P = .03). Odds ratios (95% CI) were: no support, 1.32 (0.81-2.14); noninvasive support, 0.73 (0.52-1.03); and ETT, 0.73 (0.57-0.94). Adjustment for baseline factors strengthened this effect (P = .02). Starting caffeine early resulted in larger reductions in days of respiratory support. Postmenstrual age at time of discontinuing PPV was shorter with earlier treatment (P = .01). Mean differences (95% CI) were: early, 1.35 weeks (0.90-1.81); and late 0.55 weeks (-0.11-0.99). Adjustment for baseline factors weakened this effect (P = .03). There is evidence of variable beneficial effects of caffeine. Infants receiving respiratory support appeared to derive more neurodevelopmental benefits from caffeine than infants not receiving support. Earlier initiation of caffeine may be associated with a greater reduction in time on ventilation. Copyright 2010 Mosby, Inc. All rights reserved.

    Children with neurologic or neurodevelopmental disorders (NNDDs) are at increased risk of complications from influenza. Although the Advisory Committee on Immunization Practices (ACIP) has recognized NNDDs as high-risk conditions for influenza complications since 2005, little is known about influenza vaccination practices in this population. CDC collaborated with Family Voices, a national advocacy group for children with special healthcare needs, to recruit parents of children with chronic medical conditions. Parents were surveyed about their knowledge, attitudes, and practices surrounding influenza vaccination. The primary outcome of interest was parental report of vaccination, or intent to vaccinate, at the time of survey participation. CDC also collaborated with the American Academy of Pediatrics to recruit primary care and specialty physicians who provide care for high-risk children, specifically those with neurologic conditions. The primary outcome was physician recognition of ACIP high-risk influenza conditions. 2138 surveys were completed by parents of children with high-risk conditions, including 1143 with at least one NNDD. Overall, 50% of children with an NNDD were vaccinated, or their parents planned to have them vaccinated against influenza. Among all 2138 children, in multivariable analysis, the presence of a respiratory condition and prior seasonal influenza vaccination was significantly associated with receipt or planned current season influenza vaccination, but the presence of an NNDD was not. 412 pediatricians completed the provider survey. Cerebral palsy was recognized as a high-risk influenza condition by 74% of physician respondents, but epilepsy (51%) and intellectual disability (46%) were less commonly identified. Our estimates of influenza vaccination in children with NNDDs are comparable to published reports of vaccination in healthy children, which continue to be suboptimal.

    Neurodevelopmental deficits are postulated to play an important role in the etiology of persistent antisocial behavior (ASB). Yet it remains uncertain as to which particular deficits are most closely associated with ASB. We seek to advance this understanding using prospectively collected data from a birth cohort in which multiple indices of neurodevelopmental functioning and ASB were assessed. Participants (n = 2776) were members of the Providence, Rhode Island cohort of the Collaborative Perinatal Project. Information on demographic and neurodevelopmental variables was collected from pregnancy through age 7. When all offspring had reached 33 years of age an adult criminal record check was conducted. A subset of subjects also self-reported on their engagement in serious ASB. Bivariate logistic regression was used to examine the relationship between each neurodevelopmental factor and adult ASB and test whether associations varied depending on how ASB was ascertained. After controlling for background and contextual characteristics, maternal smoking during pregnancy, lower childhood verbal and performance IQ, and age 7 aggressive/impulsive behavior all significantly increased the odds of adult ASB. Associations were not modified by sex and did not depend on how ASB was assessed. However, while both males and Black participants were more likely to engage in ASB than their respective female and White counterparts, relationships were significantly stronger for official records than for self-reports. Results point to a particular subset of early neurodevelopmental risks for antisocial outcomes in adulthood. Findings also suggest that prior contradictory results are not due to the use of official records versus self-reported outcomes. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Background. Over the last few decades, an increasing number of studies have suggested a connection between neurodevelopmental problems (NDPs and body mass index (BMI. Attention deficit/hyperactivity disorder (ADHD and autism spectrum disorders (ASD both seem to carry an increased risk for developing extreme BMI. However, the results are inconsistent, and there have been only a few studies of the general population of children.Aims. We had three aims with the present study: (1 to define the prevalence of extreme (low or high BMI in the group of children with ADHD and/or ASDs compared to the group of children without these NDPs; (2 to analyze whether extreme BMI is associated with the subdomains within the diagnostic categories of ADHD or ASD; and (3 to investigate the contribution of genetic and environmental factors to BMI in boys and girls at ages 9 and 12.Method. Parents of 9- or 12-year-old twins (n = 12,496 were interviewed using the Autism—Tics, ADHD and other Comorbidities (A-TAC inventory as part of the Child and Adolescent Twin Study in Sweden (CATSS. Univariate and multivariate generalized estimated equation models were used to analyze associations between extremes in BMI and NDPs.Results. ADHD screen-positive cases followed BMI distributions similar to those of children without ADHD or ASD. Significant association was found between ADHD and BMI only among 12-year-old girls, where the inattention subdomain of ADHD was significantly associated with the high extreme BMI. ASD scores were associated with both the low and the high extremes of BMI. Compared to children without ADHD or ASD, the prevalence of ASD screen-positive cases was three times greater in the high extreme BMI group and double as much in the low extreme BMI group. Stereotyped and repetitive behaviors were significantly associated with high extreme BMIs.Conclusion. Children with ASD, with or without coexisting ADHD, are more prone to have low or high extreme BMIs than

    2017-01-01

    Full Text Available The increasing prevalence of neurodevelopmental disorders, especially autism spectrum disorders (ASD and attention deficit hyperactivity disorder (ADHD, calls for more research into the identification of etiologic and risk factors. The Developmental Origin of Health and Disease (DOHaD hypothesizes that the environment during fetal and childhood development affects the risk for many chronic diseases in later stages of life, including neurodevelopmental disorders. Epigenetics, a term describing mechanisms that cause changes in the chromosome state without affecting DNA sequences, is suggested to be the underlying mechanism, according to the DOHaD hypothesis. Moreover, many neurodevelopmental disorders are also related to epigenetic abnormalities. Experimental and epidemiological studies suggest that exposure to prenatal environmental toxicants is associated with neurodevelopmental disorders. In addition, there is also evidence that environmental toxicants can result in epigenetic alterations, notably DNA methylation. In this review, we first focus on the relationship between neurodevelopmental disorders and environmental toxicants, in particular maternal smoking, plastic-derived chemicals (bisphenol A and phthalates, persistent organic pollutants, and heavy metals. We then review studies showing the epigenetic effects of those environmental factors in humans that may affect normal neurodevelopment.

    Full Text Available The literature review deals with the specilic features of physical development in extremely premature infants weighing less than 1500 g at birth. It describes the regularities of an increment in basic physical development parameters (weight, height, and head circumference within the first year of life. Genetic factors, the specific features of a neonatal period, comorbidity, and different feeding types are shown to affect the increment rates of the physical development parameters. Emphasis is placed on the early initiation of enteral feeding and on the long-term use of fortified foods in low birthweight premature babies for the correction of energy deficiency resulting from preterm birth. The review shows that there is a relationship of the long-term outcomes of physical and psychomotor developments in low birthweight premature babies.

    2017-11-01

    Over the past several decades, neurofibromatosis type 1 (NF1) has become increasingly recognized as a neurodevelopmental disorder conferring increased risk for several important neurodevelopmental problems. In this review, we summarize the specific neurodevelopmental problems encountered in the context of NF1. These include impairments in general cognitive function, deficits in specific cognitive domains such as executive function and visuospatial processing and risk for specific learning disorders, impairments in attention and social skills and the overlap with attention-deficit-hyperactivity disorder and autism spectrum disorder, and the risk of developing other psychiatric conditions including anxiety and depression. Early recognition of these developmental impairments is important for the effective treatment of children with NF1, and further characterization is essential to improve our understanding of how mutations in the NF1 gene create the diversity of clinical neuropsychiatric symptomatology observed in this at-risk population. © 2017 Mac Keith Press.

  15. Prognosis of Full-Thickness Skin Defects in Premature Infants

    2012-09-01

    Full Text Available BackgroundIn the extremities of premature infants, the skin and subcutaneous tissue are very pliable due to immaturity and have a greater degree of skin laxity and mobility. Thus, we can expect wounds to heal rapidly by wound contraction. This study investigates wound healing of full-thickness defects in premature infant extremities.MethodsThe study consisted of 13 premature infants who had a total of 14 cases of full-thickness skin defects of the extremities due to extravasation after total parenteral nutrition. The wound was managed with intensive moist dressings with antibiotic and anti-inflammatory agents. After wound closure, moisturization and mild compression were performed.ResultsMost of the full-thickness defects in the premature infants were closed by wound contraction without granulation tissue formation on the wound bed. The defects resulted in 3 pinpoint scars, 9 linear scars, and 2 round hypertrophic scars. The wounds with less granulation tissue were healed by contraction and resulted in linear scars parallel to the relaxed skin tension line. The wounds with more granulation tissue resulted in round scars. There was mild contracture without functional abnormality in 3 cases with a defect over two thirds of the longitudinal length of the dorsum of the hand or foot. The patients' parents were satisfied with the outcomes in 12 of 14 cases.ConclusionsFull-thickness skin defects in premature infants typically heal by wound contraction with minimal granulation tissue and scar formation probably due to excellent skin mobility.

    2017-07-01

    Full Text Available A premature male infant was born at 30 weeks’ gestation with a birth weight of 1,700 g in a rural hospital. He was diagnosed with respiratory distress syndrome and received continuous positive airway pressure treatment for 26 days. At 26 days after birth, the patient was transferred to our hospital for further evaluation and management. A comprehensive eye examination revealed a stage 3 retinopathy of prematurity (ROP involving zone 2 in both eyes. The patient was recommended to a provincial-level eye hospital for emergency laser therapy. Five months after birth, the feedback from the eye hospital showed that the patient had a high risk of blindness in both eyes. Our case report shows that delaying first screening examination increases the possibility of developing aggressive posterior ROP in infants with ROP. Doctors in rural hospitals should be aware of this possibility and trained for early screening and treatment in high-risk infants.

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

    Directory of Open Access Journals (Sweden)

    Kalpashri Kesavan

    Full Text Available 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.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.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.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.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-invasive intervention to reduce apnea, bradycardia and

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

    In agreement with Canabis craniosynostosis as a little known organic partial factor of sociopathy is demonstrated. A psychic syndrome of the frontal lobe with increased susceptibility in environmental damages is assumed to be basic disorder. In the criminals of the material sexual offenders were preponderating. Associated craniofacial dysplasias are a risk for psychic maldevelopment. The importance of premature craniosynostocis as a biological risk factor, incidence, diagnostic, indication for an operation, also in the meaning of a neurosurgical "Konflikttherapie" (cosmetical indication) are discussed.

    2017-06-19

    Within research into neurodevelopmental disorders, little is known about the mechanisms underpinning changes in symptom severity across development. When the behavioural presentation of a condition improves/symptoms lessen, this may be because core underlying atypicalities in cognition/neural function have ameliorated. An alternative possibility is 'compensation'; that the behavioural presentation appears improved, despite persisting deficits at cognitive and/or neurobiological levels. There is, however, currently no agreed technical definition of compensation or its behavioural, cognitive and neural characteristics. Furthermore, its workings in neurodevelopmental disorders have not been studied directly. Here, we review current evidence for compensation in neurodevelopmental disorders, using Autism Spectrum Disorder as an example, in order to move towards a better conceptualisation of the construct. We propose a transdiagnostic framework, where compensation represents the processes responsible for an observed mismatch between behaviour and underlying cognition in a neurodevelopmental disorder, at any point in development. Further, we explore potential cognitive and neural mechanisms driving compensation and discuss the broader relevance of the concept within research and clinical settings.

    Neonates with single ventricle congenital heart disease are at risk for structural cerebral abnormalities. Little is known about the further evolution of cerebral abnormalities until Fontan procedure. Between August 2012 and July 2015, we conducted a prospective cross-sectional two centre study using cerebral magnetic resonance imaging (MRI) and neuro-developmental outcome assessed by the Bayley-III. Forty-seven children (31 male) were evaluated at a mean age of 25.9 ± 3.4 months with hypoplastic left heart syndrome (25) or other single ventricle (22). Cerebral MRI was abnormal in 17 patients (36.2%) including liquor space enlargements (10), small grey (9) and minimal white (5) matter injuries. Eight of 17 individuals had combined lesions. Median (range) cognitive composite score (CCS) (100, 65-120) and motor composite score (MCS) (97, 55-124) were comparable to the reference data, while language composite score (LCS) (97, 68-124) was significantly lower ( P  = 0.040). Liquor space enlargement was associated with poorer performance on all Bayley-III subscores (CCS: P  = 0.02; LCS: P  = 0.002; MCS: P  = 0.013). The number of re-operations [odds ratio (OR) 2.2, 95% confidence interval (CI) 1.1-4.3] ( P  = 0.03) and re-interventions (OR 2.1, 95% CI 1.1-3.8) ( P  = 0.03) was associated with a higher rate of overall MRI abnormalities. Cerebral MRI abnormalities occur in more than one third of children with single ventricle, while the neuro-developmental status is less severely affected before Fontan procedure. Liquor space enlargement is the predominant MRI finding associated with poorer neuro-developmental status, warranting further studies to determine aetiology and further evolution until school-age.

    Full Text Available In recent decades there has been substantial progress in the technology of premature infants nursing, especially with extremely low birth weight. Adequate feeding is one of the fundamental factors of premature babies nursing. To ensure a premature baby with all necessary components for power saving in breast milk intake, breast milk fortifiers — specifically developed additives that adjust the composition of food for premature babies, are used for more than 20 years (for premature babies receiving breast milk. On the one hand, to preserve all benefits of breastfeeding, on the other — to prevent the deficit development of necessary elements for adequate growth and development of nutrients.

    The restricted availability of suitable in vitro models that can reliably represent complex human brain development is a significant bottleneck that limits the translation of basic brain research into clinical application. While induced pluripotent stem cells (iPSCs) have replaced the ethically questionable human embryonic stem cells, iPSC-based neuronal differentiation studies remain descriptive at the cellular level but fail to adequately provide the details that could be derived from a complex, 3D human brain tissue. This gap is now filled through the application of iPSC-derived, 3D brain organoids, "Brains in a dish," that model many features of complex human brain development. Here, a method for generating iPSC-derived, 3D brain organoids is described. The organoids can help with modeling autosomal recessive primary microcephaly (MCPH), a rare human neurodevelopmental disorder. A widely accepted explanation for the brain malformation in MCPH is a depletion of the neural stem cell pool during the early stages of human brain development, a developmental defect that is difficult to recreate or prove in vitro. To study MCPH, we generated iPSCs from patient-derived fibroblasts carrying a mutation in the centrosomal protein CPAP. By analyzing the ventricular zone of microcephaly 3D brain organoids, we showed the premature differentiation of neural progenitors. These 3D brain organoids are a powerful in vitro system that will be instrumental in modeling congenital brain disorders induced by neurotoxic chemicals, neurotrophic viral infections, or inherited genetic mutations.

    A case-control study was undertaken of 471 children on the Nottingham Special Needs Register (SNR) who were born in one of the two maternity units in the city between 1987 and 1993 (inclusive). Controls were selected as the next infant born at the same hospital following each index case. The aim of the study was to identify risk factors on the Nottingham Obstetric Database for a baby subsequently appearing on the SNR. Disability was analysed by both ICD-9 coding and functional assessment. Factors which independently and significantly predicted a child's likelihood of being on the SNR were breech presentation (adjusted odds ratio (OR) = 4.0), congenital abnormality (OR=4.9), intrapartum fetal distress (OR=1.7), fetal growth restriction (OR=2.0), socioeconomic deprivation (OR=1.8), prematurity (OR=2.2), reduced fetal movements (OR=2.5) and medication in pregnancy (OR=10.4). To our knowledge the last two factors have not previously been reported as risk predictors for neurodevelopmental disability.

  16. Motor Abnormalities: From Neurodevelopmental to Neurodegenerative Through "Functional" (Neuro)Psychiatric Disorders.

    2017-09-01

    Motor abnormalities (MAs) of severe mental disorders have been traditionally neglected both in clinical practice and research, although they are an increasing focus of attention because of their clinical and neurobiological relevance. For historical reasons, most of the literature on MAs has been focused to a great extent on schizophrenia, and as a consequence their prevalence and featural properties in other psychiatric or neuropsychiatric disorders are poorly known. In this article, we evaluated the extent to which catatonic, extrapyramidal and neurological soft signs, and their associated clinical features, are present transdiagnostically. We examined motor-related features in neurodevelopmental (schizophrenia, obsessive compulsive disorder, autism spectrum disorders), "functional" (nonschizophrenic nonaffective psychoses, mood disorders) and neurodegenerative (Alzheimer's disease) disorders. Examination of the literature revealed that there have been very few comparisons of motor-related features across diagnoses and we had to rely mainly in disorder-specific studies to compare it transdiagnostically. One or more motor domains had a substantial prevalence in all the diagnoses examined. In "functional" disorders, MAs, and particularly catatonic signs, appear to be markers of episode severity; in chronic disorders, although with different degree of strength or evidence, all motor domains are indicators of both disorder severity and poor outcome; lastly, in Alzheimer's disease they are also indicators of disorder progression. MAs appear to represent a true transdiagnostic domain putatively sharing neurobiological mechanisms of neurodevelopmental, functional or neurodegenerative origin.

  17. Premature birth and diseases in premature infants: common genetic background?

    2012-04-01

    It has been proposed that during human evolution, development of obligate bipedalism, narrow birth canal cross-sectional area and the large brain have forced an adjustment in duration of pregnancy (scaling of gestational age; Plunkett 2011). Children compared to other mammals are born with proportionally small brains (compared to adult brains), suggesting shortening of pregnancy duration during recent evolution. Prevalence of both obstructed delivery and premature birth is still exceptionally high. In near term infants, functional maturity and viability is high, and gene variants predisposing to respiratory distress syndrome (RDS) are rare. Advanced antenatal and neonatal treatment practices during the new era of medicine allowed survival of also very preterm infants (gestation premature birth. Specific genes associating with diseases in preterm infants may also contribute to the susceptibility to preterm birth. Understanding and applying the knowledge of genetic interactions in normal and abnormal perinatal-neonatal development requires large, well-structured population cohorts, studies involving the whole genome and international interdisciplinary collaboration.

    Full Text Available Premature rupture of membranes (PROM is one of the most common complications of pregnancy that has a major impact on neonatal outcomes. With respect to racial, nutritional and cultural differences between developed and developing countries, this study was conducted to detect the prevalence of neonatal complications following PROM and the role of the duration of rupture of membranes in producing morbidities and mortalities in these neonates in our hospital. Among 2357 pregnant women, we found 163 (6.91% cases of premature rupture of the fetal membranes in Tehran Vali-e-Asr Hospital during April 2001 to April 2002. Route of delivery was cesarean section in 65.6% of women. Urinary tract infection occured in 1.8%, maternal leukocytosis and fever in 20.2% and 5.5%, chorioamnionitis in 6.1%, fetal tachycardia in 1.2% and olygohydramnios in 4.9%. Gestational age in 138 (86% of neonates was less than 37 completed weeks. Thirty five infants (21.47% had respiratory distress syndrome and 33 (20.245% had clinical sepsis. Pneumonia in 6 (3.7% and skeletal deformity in 7 (4.294% were seen. Rupture of membrane of more than 24 hours duration occurred in 71 (43.6% of the patients. Comparison of morbidities between two groups of neonates and their mothers according to the duration of PROM (less and more than 24 hours showed significant differences in NICU admission, olygohydramnios, maternal fever, leukocytosis and chorioamnionitis rates (p24 hr of PROM with an odds ratio of 2.68 and 2.73, respectively. Positive blood and eye cultures were detected in 16 cases during 72 hours of age. Staphylococcus species, klebsiella, E.coli and streptococcus were the predominant organisms among positive blood cultures. Mortality was seen in 18 (11% of neonates because of respiratory failure, disseminated intravascular coagulation, septic shock, and a single case of congenital toxoplasmosis.

    The aim of the study was to determine the impact of increasing doses of 2 prebiotic oligosaccharides and of an "all-human diet" on the intestinal microbiota of premature infants. Twelve premature infants receiving formula feedings were randomly assigned to receive either galacto-oligosaccharide (F+GOS) or a pooled concentrated donor human milk product containing human milk oligosaccharides (F+HMO) in increasing doses during a 5-week period. A second group of 15 premature infants received their mother's own milk fortified with either a concentrated donor human milk product (H+H) or a bovine powdered fortifier (H+B). Serial stool specimens from each infant were analyzed by terminal restriction fragment length polymorphism and quantitative polymerase chain reaction for bacterial composition. All of the infants studied had relatively low levels of bifidobacteria and no measurable Lactobacilli. Infants from the F+GOS and F+HMO groups demonstrated an increase in relative numbers of Clostridia with increasing doses. Compared with the H+B group, the infants in the F+HMO and the H+H groups showed an unexpected trend toward an increase in γ-Proteobacteria over time/dose. Principal coordinate analyses and Shannon diversity scores were not significantly different among the 4 groups. Infants in the H+H group received more antibiotics during the study period than those in the other groups. Two of the infants receiving GOS developed feeding intolerance. None of the prebiotic interventions resulted in significant increases in bifidobacteria compared with baseline specimens or the H+B group; however, many of the infants did not receive the highest doses of GOS and HMO, and antibiotic use in the H+H group was high.

    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.

    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.

    Autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) are neurodevelopmental disorders which occur in childhood and may persist into adulthood. Although the etiology of these disorders is largely unknown, genetic and environmental factors are thought to play a role in the development of ASD and ADHD. Allergic immune reactions, in prenatal and postnatal phases, are examples of these environmental factors, and adverse reactions to foods are reported in these children. In this review, we address the clinical and preclinical findings of (food) allergy in ASD and ADHD and suggest possible underlying mechanisms. Furthermore, opportunities for nutritional interventions in neurodevelopmental disorders are provided. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2015-04-01

    Most research on neurodevelopmental disorders has focused on their abnormalities. However, what remains intact may also be important. Increasing evidence suggests that declarative memory, a critical learning and memory system in the brain, remains largely functional in a number of neurodevelopmental disorders. Because declarative memory remains functional in these disorders, and because it can learn and retain numerous types of information, functions, and tasks, this system should be able to play compensatory roles for multiple types of impairments across the disorders. Here, we examine this hypothesis for specific language impairment, dyslexia, autism spectrum disorder, Tourette syndrome, and obsessive-compulsive disorder. We lay out specific predictions for the hypothesis and review existing behavioral, electrophysiological, and neuroimaging evidence. Overall, the evidence suggests that declarative memory indeed plays compensatory roles for a range of impairments across all five disorders. Finally, we discuss diagnostic, therapeutic and other implications. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The number of children with mild neurodevelopmental disorders, such as autism, has been recently increasing in advanced countries. This increase is probably caused by environmental factors rather than genetic factors, because it is unlikely that genetic mutation rates suddenly increased within a short period. Epigenetics is a mechanism that regulates gene expression, depending not on the underlying DNA sequence but on the chemical modifications of DNA and histone proteins. Because mental stre...

    Schizophrenia has a neurodevelopmental component to its origin, and may share overlapping pathogenic mechanisms with childhood neurodevelopmental disorders (NDs). Nevertheless, longitudinal studies of psychotic outcomes among individuals with NDs are limited. We report a population-based prospective study of six common childhood NDs, subsequent neurocognitive performance and the risk of psychotic experiences (PEs) in early adolescence. PEs were assessed by semi-structured interviews at age 13 years. IQ and working memory were measured between ages 9 and 11 years. The presence of six NDs (autism spectrum, dyslexia, dyspraxia, dysgraphia, dysorthographia, dyscalculia) was determined from parent-completed questionnaires at age 9 years. Linear regression calculated the mean difference in cognitive scores between children with and without NDs. Associations between NDs and PEs were expressed as odds ratios (ORs) with 95% confidence intervals (CIs); effects of cognitive deficits were examined. Potential confounders included age, gender, father's social class, ethnicity and maternal education. Out of 8220 children, 487 (5.9%) were reported to have NDs at age 9 years. Children with, compared with those without, NDs performed worse on all cognitive measures; the adjusted mean difference in total IQ was 6.84 (95% CI 5.00-8.69). The association between total IQ and NDs was linear (p memory) deficit partly explained this association. Higher risk of PEs in early adolescence among individuals with childhood ND is consistent with the neurodevelopmental hypothesis of schizophrenia.

  11. Subjective Experience of Episodic Memory and Metacognition: A Neurodevelopmental Approach

    Full Text Available Episodic retrieval is characterized by the subjective experience of remembering. This experience enables the co-ordination of memory retrieval processes and can be acted on metacognitively. In successful retrieval, the feeling of remembering may be accompanied by recall of important contextual information. On the other hand, when people fail (or struggle to retrieve information, other feelings, thoughts and information may come to mind. In this review, we examine the subjective and metacognitive basis of episodic memory function from a neurodevelopmental perspective, looking at recollection paradigms (such as source memory, and the report of recollective experience and metacognitive paradigms such as the feeling of knowing. We start by considering healthy development, and provide a brief review of the development of episodic memory, with a particular focus on the ability of children to report first-person experiences of remembering. We then consider neurodevelopmental disorders such as amnesia acquired in infancy, autism, Williams syndrome, Down syndrome or 22q11.2 deletion syndrome. This review shows that different episodic processes develop at different rates, and that across a broad set of different neurodevelopmental disorders there are various types of episodic memory impairment, each with possibly a different character. This literature is in agreement with the idea that episodic memory is a multifaceted process.

    Prenatal infection is an environmental risk factor for various brain disorders with neurodevelopmental components, including autism spectrum disorder and schizophrenia. Modeling this association in animals shows that maternal immune activation negatively affects fetal brain development and leads to the emergence of behavioral disturbances later in life. Recent discoveries in these preclinical models suggest that epigenetic modifications may be a critical molecular mechanism by which prenatal immune activation can mediate changes in brain development and functions, even across generations. This review discusses the potential epigenetic mechanisms underlying the effects of prenatal infections, thereby highlighting how infection-mediated epigenetic reprogramming may contribute to the transgenerational transmission of pathological traits. The identification of epigenetic and transgenerational mechanisms in infection-mediated neurodevelopmental disorders appears relevant to brain disorders independently of existing diagnostic classifications and may help identifying complex patterns of transgenerational disease transmission beyond genetic inheritance. The consideration of ancestral infectious histories may be of great clinical interest and may be pivotal for developing new preventive treatment strategies against infection-mediated neurodevelopmental disorders.

    Background Schizophrenia has a neurodevelopmental component to its origin, and may share overlapping pathogenic mechanisms with childhood neurodevelopmental disorders (ND). Yet longitudinal studies of psychotic outcomes among individuals with ND are limited. We report a population-based prospective study of six common childhood ND, subsequent neurocognitive performance and the risk of psychotic experiences (PEs) in early adolescence. Methods PEs were assessed by semi-structured interviews at age 13 years. IQ and working memory were measured between ages 9 and 11 years. The presence of six neurodevelopmental disorders (autism spectrum, dyslexia, dyspraxia, dysgraphia, dysorthographia, dyscalculia) was determined from parent-completed questionnaire at age 9 years. Linear regression calculated mean difference in cognitive scores between those with and without ND. The association between ND and PEs was expressed as odds ratio (OR); effects of cognitive deficits were examined. Potential confounders included age, gender, father’s social class, ethnicity and maternal education. Results Out of 8,220 children, 487 (5.9%) were reported to have ND at age 9 years. Children with, compared with those without ND performed worse on all cognitive measures; adjusted mean difference in total IQ 6.84 (95% CI 5.00- 8.69). The association between total IQ and ND was linear (p<0.0001). The risk of PEs was higher in those with, compared with those without ND; adjusted OR for definite PEs 1.76 (95% CI 1.11- 2.79). IQ (but not working memory) deficit partly explained this association. Conclusion Higher risk of PEs in early adolescence among individuals with childhood ND is consistent with the neurodevelopmental hypothesis of schizophrenia. PMID:25066026

  14. Behavioral and neuroanatomical outcomes in a rat model of preterm hypoxic-ischemic brain Injury: Effects of caffeine and hypothermia.

    The current study investigated behavioral and post mortem neuroanatomical outcomes in Wistar rats with a neonatal hypoxic-ischemic (HI) brain injury induced on postnatal day 6 (P6; Rice-Vannucci HI method; Rice et al., 1981). This preparation models brain injury seen in premature infants (gestational age (GA) 32-35 weeks) based on shared neurodevelopmental markers at time of insult, coupled with similar neuropathologic sequelae (Rice et al., 1981; Workman et al., 2013). Clinically, HI insult during this window is associated with poor outcomes that include attention deficit hyperactivity disorder (ADHD), motor coordination deficits, spatial memory deficits, and language/learning disabilities. To assess therapies that might offer translational potential for improved outcomes, we used a P6 HI rat model to measure the behavioral and neuroanatomical effects of two prospective preterm neuroprotective treatments - hypothermia and caffeine. Hypothermia (aka "cooling") is an approved and moderately efficacious intervention therapy for fullterm infants with perinatal hypoxic-ischemic (HI) injury, but is not currently approved for preterm use. Caffeine is a respiratory stimulant used during removal of infants from ventilation but has shown surprising long-term benefits, leading to consideration as a therapy for HI of prematurity. Current findings support caffeine as a preterm neuroprotectant; treatment significantly improved some behavioral outcomes in a P6 HI rat model and partially rescued neuropathology. Hypothermia treatment (involving core temperature reduction by 4 °C over 5 hours), conversely, was found to be largely ineffective and even deleterious for some measures in both HI and sham rats. These results have important implications for therapeutic intervention in at-risk preterm populations, and promote caution in the application of hypothermia protocols to at-risk premature infants without further research.

    2017-02-08

    Animal models offer heuristic research tools to understand the causes of human diseases and to identify potential treatments. With rapidly evolving genetic engineering technologies, mutations identified in a human disorder can be generated in the mouse genome. Phenotypic outcomes of the mutation are then explicated to confirm hypotheses about causes and to discover effective therapeutics. Most neurodevelopmental, neurodegenerative, and psychiatric disorders are diagnosed primarily by their prominent behavioral symptoms. Mouse behavioral assays analogous to the human symptoms have been developed to analyze the consequences of mutations and to evaluate proposed therapeutics preclinically. Here we describe the range of mouse behavioral tests available in the established behavioral neuroscience literature, along with examples of their translational applications. Concepts presented have been successfully used in other species, including flies, worms, fish, rats, pigs, and nonhuman primates. Identical strategies can be employed to test hypotheses about environmental causes and gene × environment interactions.

    Full Text Available Objective: to reveal the factors that are responsible for the development of respiratory distress syndrome (RDS and the specific features of its course in preterm twin neonates. Subjects and methods. Twenty-three patients who had had twin pregnancy, including 9 (39.1% and 14 (60% with monochorial and bichorial biamniotic twin pregnancies, respectively, were examined. Their mean age was 28.5±5.4 years. Obstetric and gynecologic histories, conditions at conception, the course of pregnancy, the type of pla-centation, and fetal presentation were considered. The placentas were morphologically examined. In all the patients, pregnancy ended in birth of 46 premature neonates, of them there were 19 (41.3% boys and 27 (58.7% girls. The gestational age of the neonates averaged 31.7±2.3 weeks. The evaluation of the efficiency of performed therapy used clinical assessment of the status of the premature neonates; measurement of partial oxygen tension (pO2 and calculation of alveolar-arterial oxygen gradient (A-a DO2, respiratory index (RI, and oxygenation index (OI; death rates were analyzed. Results. The main cause of respiratory failure (RF was RDS in premature twins. Neonatal blood aspiration-caused pneumonia occurred in one case. The course of RDS was variable. Most neonatal infants needed exogenous surfactant replacement therapy and mechanical ventilation (MV. No signs of RF were present in 7 (15.2% premature neonates. Conclusion. Premature twins are a high RDS risk group. The unfavorable factors that contribute to the development of the disease are multiple pregnancy, a past maternal obstetric history, in-vitro fertilization-induced pregnancy, severe gestosis in the second half of pregnancy, and preterm delivery. The type of placentation affects the fetal status after birth. Fatal outcome occurred in infants from the monochorial bioamniotic twins. In multiple pregnancies, there are pathological changes in the placenta, its membranes, and umbilical

    2001-01-01

    OBJECTIVE—To determine the effect of birth order on respiratory distress syndrome (RDS) in the outcome of twins in a large premature population managed in a modern neonatal intensive care unit.
METHODS—An historical cohort study design was used to analyse the neonatal outcomes of 301 premature liveborn twin sibling pairs of between 23 and 31 weeks gestation from the Australia and New Zealand Neonatal Network 1995database.
RESULTS—Among the 56 twin sibling pairs who were discordant for RDS, the second twin was affected in 41 cases (odds ratio (OR) 2.7,95% confidence interval (CI) 1.5 to 5.3). The excess risk of RDS in the second twin increased with gestation and was statistically significant for twins above 29 weeks gestation (OR 4.4, 95% CI 1.6 to 15).
CONCLUSIONS—There is a significant increased risk of RDS associated with being the second born of premature twins, which appears to depend on gestation.

    2012-01-01

    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.

    high concentrations of maternal C-reactive protein have been associated with adverse pregnancy outcome, and premature uterine contraction may be predicted by elevated levels of C-reactive protein. This may ultimately be simple and cost-effective enough to introduce as a low-risk screening program. an observational case control study was performed from May 1st, 2010 to December 1st, 2010 at Maternity Teaching Hospital-Erbil/ Kurdistan Region/ Iraq. The sample size was (200) cases. Hundred of them were presented with premature uterine contractions at 24(+0)-36(+6) weeks. The other hundred were control group at same gestational ages. The level of C-reactive protein was determined in both groups and both groups were followed till delivery. (93) out of (100) women with premature uterine contractions had elevated level of C-Reactive protein and 91% delivered prematurely while in the control group only (9) out of (100) women had elevated level of C-reactive protein and only 8% of them delivered preterm. Differences were statistically highly significant. C-reactive protein can be used as a biomarker in prediction of premature delivery when it is associated with premature uterine contractions. As well it can be used as a screening test to detect cases that are at risk of premature delivery.

    To examine differences in the growth pattern and the age at adiposity rebound (AR) between children with premature adrenarche (PA) and their healthy peers (controls). In this cross-sectional study of 82 prepubertal children with PA and 63 controls, the main outcome measures were height and body mass index SDS progression, from birth to presentation at the clinic, baseline biochemical and hormonal evaluation, bone age determination, and age at AR. Children with PA were significantly taller and more adipose than controls from the first years of life. 33% of children with PA presented the growth pattern of constitutional advancement of growth (ie, early growth acceleration) vs 19% of controls (P = .045). Children with PA had an earlier AR compared with controls; mean age at AR in girls with PA was 3.73 (1.03) years vs 4.93 (1.36) years for control girls (P = .001) and in boys with PA was 3.45 (0.73) vs 5.10 (1.50) years in control boys (P = .048). Both obese and nonobese girls with PA were taller and had earlier age at AR compared with nonobese controls. Early AR and constitutional advancement of growth may be triggering factors for adrenal androgen production and PA. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available A dysfunction of cortical and limbic GABAergic circuits has been postulated to contribute to multiple neurodevelopmental disorders in humans, including schizophrenia, autism, and epilepsy. In the current paper, I summarize the characteristics that underlie the great diversity of cortical GABAergic interneurons and explore how the multiple roles of these cells in developing and mature circuits might contribute to the aforementioned disorders. Furthermore, I review the tightly controlled genetic cascades that determine the fate of cortical interneurons and summarize how the dysfunction of genes important for the generation, specification, maturation, and function of cortical interneurons might contribute to these disorders.

    Prematurity and intrauterine growth restriction are associated with neurodevelopmental disabilities. To assess the relationship between growth status and regional brain volume (rBV) and white matter microstructure in premature babies at around term-equivalent age. Premature infants (n= 27) of gestational age (GA): 29.8 ± 2.1 weeks, with normal brain MRI scans were studied at corrected age: 41.2 ± 1.4 weeks. The infants were divided into three groups: 1) appropriate for GA at birth and at the time of MRI (AGA), 2) small for GA at birth with catch-up growth at the time of MRI (SGA{sub a}) and 3) small for GA at birth with failure of catch-up growth at the time of MRI (SGA{sub b}). The T1-weighted images were segmented into 90 rBVs using the SPM8/IBASPM and differences among groups were assessed. Fractional anisotropy (FA) was measured bilaterally in 15 fiber tracts and its relationship to GA and somatometric measurements was explored. Lower rBV was observed in SGA{sub b} in superior and anterior brain areas. A positive correlation was demonstrated between FA and head circumference and body weight. Body weight was the only significant predictor for FA (P< 0.05). In premature babies, catch-up growth is associated with regional brain volume catch-up at around term-equivalent age, starting from the brain areas maturing first. Body weight seems to be a strong predictor associated with WM microstructure in brain areas related to attention, language, cognition, memory and executing functioning. (orig.)

  12. Ethical dilemmas in the care of the most premature infants: the waters are murkier than ever.

    Science.gov (United States)

    Lorenz, John M

    2005-04-01

    Summarize the literature relevant to ethical issues surrounding decisions to provide intensive care to extremely premature newborns. A Texas Supreme Court decision and a position paper are noteworthy for health professionals participating in management decisions with families at risk for extremely preterm delivery. In Miller v HCA, the Millers sued the Hospital Corporation of America for resuscitating their approximately 23-week gestation daughter against their wishes. The baby survived with severe neurodevelopmental disabilities. They were awarded $59.9 million in a jury trial. However, the judgment was reversed by the court of appeals, which ruled that parents have no right to withhold urgently needed life-sustaining medical treatment from children with non-terminal impairments, deformities, or disabilities, regardless of their severity. The Supreme Court of Texas upheld that ruling, but reasoned that parents have no right to refuse resuscitation of extremely premature infants prior to birth because they cannot be fully evaluated until birth; therefore, decisions before birth could not be fully informed. Robertson (Hasting Center Report 2004) supports precluding parental refusal of resuscitation before birth. He argues that parents have a right to withhold or withdraw medical treatment from a non-terminally ill child, but only if the child will lack capacity for symbolic interaction. Such severe limitation of quality of life concerns in decision making for extremely premature newborns is inconsistent with current published guidelines, the positions of noted bioethicists, and the practice of many neonatologists. Further, the additional information attained by initiating intensive care in the most premature infants does not justify doing so without parental consent.

  13. [Sexological intervention on premature ejaculation].

    San Martín Blanco, C

    2014-07-01

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

    At school age extremely low birth weight (ELBW) and extremely low gestational age (ELGAN) children are more likely to show Learning Disabilities (LDs) and difficulties in emotional regulation. The aim of this study was to investigate the incidence of LDs at school age and to detect neurodevelopmental indicators of risk for LDs at preschool ages in a cohort of ELBW/ELGAN children with broadly average intelligence. All consecutively newborns 2001-2006 admitted to the same Institution entered the study. Inclusion criteria were BW learning disabilities at school age was investigated through a parent-report questionnaire at children's age range 9-10 years. Neurodevelopmental profiles were assessed through the Griffiths Mental Development Scales at 1 and 2 years of corrected age and at 3, 4, 5, and 6 years of chronological age and were analyzed comparing two groups of children: those with LDs and those without. At school age 24 on 102 (23.5%) of our ELBW/ELGAN children met criteria for LDs in one or more areas, with 70.8% comorbidity with emotional/attention difficulties. Children with LDs scored significantly lower in the Griffiths Locomotor and Language subscales at 2 years of corrected age and in the Personal-social, Performance and Practical Reasoning subscales at 5 years of chronological age. Our findings suggest that, among the early developmental indicators of adverse school outcome, there is a poor motor experimentation, language delay, and personal-social immaturity. Cognitive rigidity and poor ability to manage practical situations also affect academic attainment. Timely detection of these early indicators of risk is crucial to assist the transition to school.

    Studies report conflicting associations between preeclampsia and retinopathy of prematurity (ROP). This study provides explanations for the discrepancies to clarify the relationship between preeclampsia and ROP. To evaluate the association of maternal preeclampsia and risk of ROP among infants in an unrestricted birth cohort and a restricted subcohort of preterm, very low birth weight (P-VLBW) infants. A retrospective review of 290 992 live births within the Intermountain Healthcare System in Utah from January 1, 2001, through December 31, 2010, was performed. Generalized estimating equations for logistic regressions with covariate adjustment were applied to relate ROP to preeclampsia among the full cohort and in a subcohort of P-VLBW infants born at younger than 31 weeks' gestation and weighing less than 1500 g. The occurrence of ROP was related to maternal preeclampsia in the full cohort and in a subcohort of P-VLBW infants. In the full cohort, 51% of the infants were male and the mean (SD) gestational age was 38.38 (1.87) weeks. In the P-VLBW cohort, 55% were male and the mean (SD) gestational age was 26.87 (2.40) weeks. In the full cohort, preeclampsia was associated with an increased risk of all ROP (adjusted odds ratio [aOR], 2.46; 95% CI, 2.17-2.79; P preeclampsia was inversely associated with the development of all ROP (aOR, 0.79; 95% CI, 0.68-0.92; P = .003), severe ROP (aOR, 0.62; 95% CI, 0.36-1.06; P = .08), and infant death (aOR, 0.19; 95% CI, 0.11-0.32; P Preeclampsia was associated with an increased risk of developing ROP among an unrestricted cohort but with a reduced risk of ROP among a restricted subcohort of P-VLBW infants. Although the conflicting associations in the full and P-VLBW cohorts may reflect true differences, the association of a reduced risk of ROP among the P-VLBW subcohort also may reflect biases from restricting the cohort to prematurity, because prematurity is an outcome of preeclampsia.

    To compare the interactive behaviors of American Indian mothers and their premature infants with those of African American mothers and their premature infants. Descriptive, comparative study. Three neonatal intensive care units and two pediatric clinics in the southeast. Seventy-seven mother/infant dyads: 17 American Indian mother/infant dyads and 60 African American mother/infant dyads. Videotapes of mother/infant interactions and the Home Observation for Measurement of the Environment (HOME) were used to assess the interactions of the mothers and their premature infants at 6 months corrected age. American Indian mothers looked more, gestured more, and were more often the primary caregivers to their infants than the African American mothers. American Indian infants expressed more positive affect and gestured more to their mothers, whereas African American infants engaged in more non-negative vocalization toward their mothers. African American mothers scored higher on the HOME subscales of provision of appropriate play materials and parental involvement with the infant. American Indian mothers scored higher on the opportunities for variety in daily living subscale. Although many of the interactive behaviors of American Indian and African American mother/infant dyads were similar, some differences did occur. Clinicians need to be aware of the cultural differences in mother/infant interactions. To optimize child developmental outcomes, nurses need to support mothers in their continuation or adoption of positive interactive behaviors. © 2013 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

    Docosahexaenoic acid (DHA) is an essential fatty acid (FA) important for health and neurodevelopment. Premature infants are at risk of DHA deficiency and circulating levels directly correlate with health outcomes. Most supplementation strategies have focused on increasing DHA content in mother's milk or infant formula. However, extremely premature infants may not reach full feedings for weeks and commercially available parenteral lipid emulsions do not contain preformed DHA, so blood levels decline rapidly after birth. Our objective was to develop a DHA supplementation strategy to overcome these barriers. This double-blind, randomized, controlled trial determined feasibility, tolerability and efficacy of daily enteral DHA supplementation (50 mg/day) in addition to standard nutrition for preterm infants (24-34 weeks gestational age) beginning in the first week of life. Blood FA levels were analyzed at baseline, full feedings and near discharge in DHA (n = 31) or placebo supplemented (n = 29) preterm infants. Term peers (n = 30) were analyzed for comparison. Preterm infants had lower baseline DHA levels (p DHA had a progressive increase in circulating DHA over time (from 3.33 to 4.09 wt% or 2.88 to 3.55 mol%, p DHA supplementation, preterm infants still had lower blood DHA levels than term peers (4.97 wt% or 4.31 mol%) at discharge (p = 0.0002). No differences in adverse events were observed between the groups. Overall, daily enteral DHA supplementation is feasible and alleviates deficiency in premature infants.

    Full Text Available Objective. We aimed to investigate the incidence and the severity of retinopathy of extremely premature infants and to evaluate the risk factors and outcome of the cases. Materials and Methods. Out of 200 premature births, we retrospectively reviewed 9 cases that developed ROP. We excluded cases where ROP developed in newborns > 30 weeks of gestational age and cases where medical notes were unavailable or incomplete. Topical drops of cyclopentolate 1% and phenylephrine 5% were instilled and fundoscopy was performed using a direct ophthalmoscope. Results. The incidence of ROP was 4.5% in the 9-year period. The infants were divided into two groups. Group 1 included premature infants ≤27 weeks of age and Group 2 included those >27 weeks but ≤ 30 weeks of age. We found that the infants of Group 1 showed advanced stages of ROP in comparison to Group 2. Out of 18 eyes, 11 eyes had stage 3 ROP and they were all found in Group 1 (100% of cases. Conclusion. The severity of ROP was associated with earlier gestational age, lower birth weight, and oxygen supplementation. Constant cooperation between physicians and nursing staff is necessary to avoid undetected cases and further prevent ROP related blindness.

    Full Text Available 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.

The traditional perception has been patient discontinuation is mainly driven by unwanted side effects. Systematic analysis of data from clinical trials across several disease states was performed to identify predictors of premature discontinuation during clinical interventions.Methods: A post hoc analysis was conducted on 22 randomized, double-blind, placebo-controlled clinical trials for treatment of fibromyalgia, diabetic peripheral neuropathic pain, major depressive disorder, and generalized anxiety disorder. Analyses were conducted on pooled data within each disease state.Results: Lack of early therapeutic response was a significant predictor of patient discontinuation in each disease state. Visit-wise changes in therapeutic response and severity of adverse events were also significant risk factors, with change in therapeutic response having a higher significance level in three disease states. Patients who discontinued due to adverse events had similar therapeutic responses as patients completing treatment.Conclusion: Contrary to the conventional belief that premature treatment discontinuation is primarily related to adverse events, our findings suggest lack of therapeutic response also plays a significant role in patient attrition. This research highlights the importance of systematic monitoring of therapeutic response in clinical practice as a measure to prevent patients’ discontinuation from pharmacological treatments.Keywords: attrition, depression, generalized anxiety disorder, fibromyalgia, therapeutic response, adverse event

    Full Text Available The number of children with mild neurodevelopmental disorders, such as autism, has been recently increasing in advanced countries. This increase is probably caused by environmental factors rather than genetic factors, because it is unlikely that genetic mutation rates suddenly increased within a short period. Epigenetics is a mechanism that regulates gene expression, depending not on the underlying DNA sequence but on the chemical modifications of DNA and histone proteins. Because mental stress can alter the epigenetic status in neuronal cells, environmental factors may alter brain function through epigenetic changes. However, one advantage of epigenetic changes is their reversibility. Therefore, diseases due to abnormal epigenetic regulation are theoretically treatable. In fact, several drugs for treating mental diseases are known to have restoring effects on aberrant epigenetic statuses, and a novel therapeutic strategy targeting gene has been developed. In this review, we discuss epigenetic mechanisms of congenital and acquired neurodevelopmental disorders, drugs with epigenetic effects, novel therapeutic strategies for epigenetic diseases, and future perspectives in epigenetic medicine.

    Sleep disorders in individuals with developmental difficulties continue to be a significant challenge for families, carers, and therapists with a major impact on individuals and carers alike. This review is designed to update the reader on recent developments in this area. A systematic search identified a variety of studies illustrating advances in the regulation of circadian rhythm and sleep disturbance in neurodevelopmental disorders. Specific advances are likely to lead in some disorders to targeted therapies. There is strong evidence that behavioural and sleep hygiene measures should be first line therapy; however, studies are still limited in this area. Nonpharmacological measures such as exercise, sensory interventions, and behavioural are reported. Behavioural regulation and sleep hygiene demonstrate the best evidence for improved sleep parameters in individuals with neurodisability. Although the mainstay of management of children with sleep problems and neurodevelopmental disability is similar to that of typically developing children, there is emerging evidence of behavioural strategies being successful in large-scale trials and the promise of more targeted therapies for more specific resistant disorders.

    Full Text Available Abstract Background Imbalances in the regulation of pro-inflammatory cytokines have been increasingly correlated with a number of severe and prevalent neurodevelopmental disorders, including autism spectrum disorder, schizophrenia and Down syndrome. Although several studies have shown that cytokines have potent effects on neural function, their role in neural development is still poorly understood. In this study, we investigated the link between abnormal cytokine levels and neural development using the Xenopus laevis tadpole visual system, a model frequently used to examine the anatomical and functional development of neural circuits. Results Using a test for a visually guided behavior that requires normal visual system development, we examined the long-term effects of prolonged developmental exposure to three pro-inflammatory cytokines with known neural functions: interleukin (IL-1β, IL-6 and tumor necrosis factor (TNF-α. We found that all cytokines affected the development of normal visually guided behavior. Neuroanatomical imaging of the visual projection showed that none of the cytokines caused any gross abnormalities in the anatomical organization of this projection, suggesting that they may be acting at the level of neuronal microcircuits. We further tested the effects of TNF-α on the electrophysiological properties of the retinotectal circuit and found that long-term developmental exposure to TNF-α resulted in enhanced spontaneous excitatory synaptic transmission in tectal neurons, increased AMPA/NMDA ratios of retinotectal synapses, and a decrease in the number of immature synapses containing only NMDA receptors, consistent with premature maturation and stabilization of these synapses. Local interconnectivity within the tectum also appeared to remain widespread, as shown by increased recurrent polysynaptic activity, and was similar to what is seen in more immature, less refined tectal circuits. TNF-α treatment also enhanced the

    Full Text Available Objective: to identify mothers' perceptions about the pain in their premature babies in the Neonatal Intensive Care Unit. Methods: evaluative, quantitative study with investigative nature conducted with 19 mothers of hospitalized premature newborns. Data were obtained from closed questions, answered by mothers. Results: from the participants, two (10.5% reported that newborns are unable to feel pain. From the 17 mothers who said that premature babies can feel pain, the majority (94.1% identified crying as a characteristic of pain sensation. Eleven (64.7% stated that uneasiness is a sign of pain in newborns. Conclusion: for the proper management of neonatal pain it is essential that mothers know the signs of pain in premature newborns, and that health professionals instruct this recognition, through the enhancement of the maternal presence and practice of effective communication between professionals and newborns’ families.

    Retinopathy of prematurity is an adverse outcome of preterm birth and is a leading cause of childhood blindness. The relationship between the subtypes of preterm birth with retinopathy of prematurity is understudied. To investigate whether there is a difference in the incidence of type 1 or type 2 retinopathy of prematurity in infants with preterm birth resulting from spontaneous preterm labor, a medical indication of preterm birth, or preterm premature rupture of the membranes. A retrospective cohort study was conducted of 827 infants screened for retinopathy of prematurity who were delivered at a single tertiary care center in Colorado. All infants fulfilled the American Academy of Pediatrics 2013 screening criteria for retinopathy of prematurity defined as "infants with a birth weight of ≤1500 g or gestational age of 30 weeks or less (as defined by the attending neonatologist) and selected infants with a birth weight between 1500 and 2000 g or gestational age of >30 weeks with an unstable clinical course, including those requiring cardiorespiratory support and who are believed by their attending pediatrician or neonatologist to be at high risk for retinopathy of prematurity." Two independent reviewers masked to retinopathy of prematurity outcomes determined whether preterm birth resulted from spontaneous preterm labor, medical indication of preterm birth, or preterm premature rupture of the membranes. Discrepancies were resolved by a third reviewer. Data were analyzed with univariate and multivariable logistic regression. In our cohort, the frequency of preterm birth resulting from spontaneous preterm labor, medical indication of preterm birth, or preterm premature rupture of the membranes was 34%, 40%, and 26%, respectively. The mean gestational age (weeks, days) ± SD (range) in the cohort and across the preterm birth subtypes was as follows: entire cohort, 28 weeks, 6 days ± 2 weeks, 3 days (23 weeks, 3 days - 36 weeks, 4 days); spontaneous preterm labor

Dental eruption of the permanent teeth in cleft palate children may be variable, with delayed eruption the most common phenomenon. A case of premature dental eruption of a maxillary left first premolar is demonstrated, however, in a five-year-old male. This localized premature dental eruption anomaly was attributed to early extraction of the primary dentition, due to caries.

    Evaluation of maternal, obstetrics e neonatal features in both spontaneous preterm births (PTB) with or without preterm premature rupture of membranes (PPROM). Retrospective study of single fetus pregnancies with PTB between 2003 and 2012. PTB associated with ou without PPROM. Exclusion criterias: PTB by medical indication due to fetal/maternal disease and all non accessible or incomplete clinical files. Different characteristics were compared between two groups of PTB: spontaneous PTB without PPROM (sPTB) versusPPROM. Kolmogorov-Smirnov, Levene, χ2, t Student and Mann-Withney tests were used for statistical analysis. From 2,393 PTB of single fetus, 1,432 files were analysed, from which 596 were sPTB and 836 PPROM. The socioeconomic conditions were similar in both groups. Multiparity (50.7 versus 40.3%), personal history of previous PTB (20.8 versus10.2%), cervical length (18.2 versus27.2 mm), lower body index mass (23.4 versus 24.3 kg/m2) and higher infectious parameters (Protein C Reactive: 2.2 versus1.2 mg/L; Leukocytes: 13.3 versus 12.4 x109) were more frequent in PBTs (p<0,001). Neonatal outcomes, specially neurologic outcomes (4.7 versus2.8%, p<0,001), were worst in PBTs. PTB with or without PPROM has a complex etiology. From all evaluated features in our study, only maternal thinness, multiparity with a previous PTB, the cervical length and worst systemic infections parameters were significant in sPTB. This group also showed worst neonatal outcomes, specially on neurological outcomes.

Aims of the study were to determine the average body weight, Apgar score after one and five minutes, and the frequency of the most common complications in preterminfants.Methods: The study involved a total of 631 newborns, of whom 331 were born prematurely Aims of this study were to (24th-37th gestational weeks-experimental group, while 300 infants were born in time (37-42 weeks of gestation-control group.Results: Average body weight of prematurely born infants was 2382 grams, while the average Apgar score in this group after the fi rst minute was 7.32 and 7.79 after the fifth minute. The incidence of respiratory distress syndrome was 50%, intracranial hemorrhage, 28.1% and 4.8% of sepsis. Respiratory distresssyndrome was more common in infants born before 32 weeks of gestation. Mortality of premature infants is present in 9.1% and is higher than that of infants born at term.Conclusions: Birth body weight and Apgar scores was lower in preterm infants. Respiratory distress syndrome is the most common fetal complication of prematurity. Intracranial hemorrhage is the second most common complication of prematurity. Mortality of premature infants is higher than the mortality of infants born at term birth.

    Vici syndrome is a progressive neurodevelopmental multisystem disorder due to recessive mutations in the key autophagy gene EPG5. We report genetic, clinical, neuroradiological, and neuropathological features of 50 children from 30 families, as well as the neuronal phenotype of EPG5 knock-down in Drosophila melanogaster. We identified 39 different EPG5 mutations, most of them truncating and predicted to result in reduced EPG5 protein. Most mutations were private, but three recurrent mutations (p.Met2242Cysfs*5, p.Arg417*, and p.Gln336Arg) indicated possible founder effects. Presentation was mainly neonatal, with marked hypotonia and feeding difficulties. In addition to the five principal features (callosal agenesis, cataracts, hypopigmentation, cardiomyopathy, and immune dysfunction), we identified three equally consistent features (profound developmental delay, progressive microcephaly, and failure to thrive). The manifestation of all eight of these features has a specificity of 97%, and a sensitivity of 89% for the presence of an EPG5 mutation and will allow informed decisions about genetic testing. Clinical progression was relentless and many children died in infancy. Survival analysis demonstrated a median survival time of 24 months (95% confidence interval 0-49 months), with only a 10th of patients surviving to 5 years of age. Survival outcomes were significantly better in patients with compound heterozygous mutations (P = 0.046), as well as in patients with the recurrent p.Gln336Arg mutation. Acquired microcephaly and regression of skills in long-term survivors suggests a neurodegenerative component superimposed on the principal neurodevelopmental defect. Two-thirds of patients had a severe seizure disorder, placing EPG5 within the rapidly expanding group of genes associated with early-onset epileptic encephalopathies. Consistent neuroradiological features comprised structural abnormalities, in particular callosal agenesis and pontine hypoplasia, delayed

    Since the results of the Management of Myelomeningocele Study were published, maternal-fetal surgery for the in utero treatment of spina bifida has become accepted as a standard of care alternative. Despite promise with fetal management of myelomeningocele repair, there are significant complications to consider. Chorioamniotic membrane separation and preterm premature rupture of membranes are known complications of invasive fetal procedures. Despite their relative frequency associated with fetal procedures, few data exist regarding risk factors that may be attributed to their occurrence or the natural history of pregnancies that are affected with chorionic membrane separation or preterm premature rupture of membranes related to the procedure. The objective of this study was to review chorioamniotic membrane separation and preterm premature rupture of membranes in a cohort of patients undergoing fetal management of myelomeningocele repair including identification of risk factors and outcomes. This was a retrospective review of patients undergoing fetal management of myelomeningocele repair and subsequent delivery from January 2011 through December 2013 at 1 institution. Patients were identified through the institutional fetal management of myelomeningocele repair database and chart review was performed. Perioperative factors and outcomes among patients with chorioamniotic membrane separation and preterm premature rupture of membranes were compared to those without. Risk factors associated with the development of chorioamniotic membrane separation and preterm premature rupture of membranes were determined. A total of 88 patients underwent fetal management of myelomeningocele repair and subsequently delivered during the study period. In all, 21 patients (23.9%) were diagnosed with chorioamniotic membrane separation by ultrasound and preterm premature rupture of membranes occurred in 27 (30.7%). Among the chorioamniotic membrane separation patients, 10 (47.6%) were

    Over the past 20-30 years, the premature ejaculation (PE) treatment paradigm, previously limited to behavioural psychotherapy, has expanded to include drug treatment. Pharmacotherapy for PE predominantly targets the multiple neurotransmitters and receptors involved in the control of ejaculation which include serotonin, dopamine, oxytocin, norepinephrine, gamma amino-butyric acid (GABA) and nitric oxide (NO). The objective of this article is to review emerging PE interventions contemporary data on the treatment of PE was reviewed and critiqued using the principles of evidence-based medicine. Multiple well-controlled evidence-based studies have demonstrated the efficacy and safety of selective serotonin reuptake inhibitors (SSRIs) in delaying ejaculation, confirming their role as first-line agents for the medical treatment of lifelong and acquired PE. Daily dosing of SSRIs is likely to be associated with superior fold increases in IELT compared to on-demand SSRIs. On-demand SSRIs are less effective but may fulfill the treatment goals of many patients. Integrated pharmacotherapy and CBT may achieve superior treatment outcomes in some patients. PDE-5 inhibitors alone or in combination with SSRIs should be limited to men with acquired PE secondary to co-morbid ED. New on-demand rapid acting SSRIs, oxytocin receptor antagonists, or single agents that target multiple receptors may form the foundation of more effective future on-demand medication. Current evidence confirms the efficacy and safety of dapoxetine, off-label SSRI drugs, tramadol and topical anaesthetics drugs. Treatment with α1-adrenoceptor antagonists cannot be recommended until the results of large well-designed RCTs are published in major international peer-reviewed medical journals. As our understanding of the neurochemical control of ejaculation improves, new therapeutic targets and candidate molecules will be identified which may increase our pharmacotherapeutic armamentarium.

    Premature ejaculation (PE) is the most common sexual dysfunction, with the majority of PE patients remaining undiagnosed and undertreated. Despite its prevalence, there is a current paucity of data regarding available treatment options and mechanisms. The objective of the current investigation is to review and summarize pertinent literature on therapeutic options for the treatment of PE, including behavioral/psychologic, oral pharmacotherapy, and surgery. A pubmed search was conducted on articles reporting data on available treatment options for PE. Articles describing potential mechanisms of action were additionally included for review. Preference was given towards randomized, controlled trials, when available. PE remains an underdiagnosed and undertreated disease process, with limited data available regarding potential underlying mechanisms and long-term outcomes of treatment options. Psychological/behavioral therapies, including the stop-start, squeeze, and pelvic floor rehabilitation techniques have demonstrated improvements in short-term series, with decreased efficacy with additional follow-up. Topical therapies, which are commonly utilized result in prolonged intravaginal ejaculatory latency time (IELT) at the expense of potential penile/vaginal Hypothesia. Oral therapies similarly demonstrate improved IELTs with variable side effect profiles and include selective serotonin reuptake inhibitors (daily or on demand), phosphodiesterase-5 inhibitors, alpha-1 adrenergic antagonists, and tramadol. Alternative therapies such as acupuncture have shown benefits in limited studies. Surgery is not commonly performed and is not recommended by available guidelines. PE is a common condition, with limited data available regarding its underlying pathophysiology and treatment. Available therapies include topical, oral, behavioral/psychologic modification, or a combination thereof. Additional research is required to assess the optimal treatment strategies and algorithms as

    There is a very substantial literature over the past 50 years on the advantages of early detection and intervention on the cognitive, communicative, and social-emotional development of infants and toddlers at risk for developmental delay due to premature birth or social disadvantage. Most of these studies excluded children with severe delays or other predisposing conditions, such as genetic or brain disorders. Many studies of children with biological or socio-developmental risk suggest that b...

    Summary Background Prenatal maternal smoking and prematurity independently affect wheezing and asthma in childhood. Objective We sought to evaluate the interactive effects of maternal smoking and prematurity upon the development of early childhood wheezing. Methods We evaluated 1448 children with smoke exposure data from a prospective urban birth cohort in Boston. Maternal antenatal and postnatal exposure was determined from standardized questionnaires. Gestational age was assessed by the first day of the last menstrual period and early prenatal ultrasound (preterm<37 weeks gestation). Wheezing episodes were determined from medical record extraction of well and ill/unscheduled visits. The primary outcome was recurrent wheezing, defined as ≥ 4 episodes of physician documented wheezing. Logistic regression models and zero inflated negative binomial regression (for number of episodes of wheeze) assessed the independent and joint association of prematurity and maternal antenatal smoking on recurrent wheeze, controlling for relevant covariates. Results In the cohort, 90 (6%) children had recurrent wheezing, 147 (10%) were exposed to in utero maternal smoke and 419 (29%) were premature. Prematurity (odds ratio [OR] 2.0; 95% CI, 1.3-3.1) was associated with an increased risk of recurrent wheezing, but in utero maternal smoking was not (OR 1.1, 95% CI 0.5-2.4). Jointly, maternal smoke exposure and prematurity caused an increased risk of recurrent wheezing (OR 3.8, 95% CI 1.8-8.0). There was an interaction between prematurity and maternal smoking upon episodes of wheezing (p=0.049). Conclusions We demonstrated an interaction between maternal smoking during pregnancy and prematurity on childhood wheezing in this urban, multiethnic birth cohort. PMID:22290763

    Premature physeal closure of the proximal femoral physis has been reported in Legg-Calve-Perthes Disease (LCPD). However, the timing of its occurrence had not yet been reported. We proposed (1) to determine the timing of premature physeal closure in unilateral LCPD with serial radiographic evaluation, and (2) to evaluate the relationship between the premature physeal closure and Herring classification, leg-length discrepancy (LLD), Stulberg classification, and trochanteric overgrowth. We performed a retrospective study with serial radiographs of 27 patients diagnosed with LCPD. The difference in the timing of physeal closure between the hips was calculated. The involved hip was classified according to Herring classification. The LLD and ATD index at latest follow up was measured. The mean values were calculated and statistical comparison of variables was done using the Fisher's exact test. The mean difference of physeal closure at the involved hip compared to the uninvolved side was 3.5 years (range, two to five years). Hips demonstrating premature physeal closure were associated with Herring B/C and C (p = 0.01) and LLD >1 cm (p = 0.02). There is no correlation between Stulberg classification, trochanteric overgrowth and premature physeal closure (p = 0.06 and p = 0.19). We may expect premature physeal closure of the proximal femoral physis in patients with LCPD to occur 3.5 years earlier than normal hips. Presence of premature physeal closure can be an adjunct diagnostic tool in the prognostication of LCPD outcomes. Future studies directed toward premature physeal closure in LCPD and associated growth disturbances are necessary.

Despite the good neurodevelopment, children classified at risk should be monitored for development throughout childhood.

  6. The genetic relationship between handedness and neurodevelopmental disorders☆

    2014-01-01

    Handedness and brain asymmetry have been linked to neurodevelopmental disorders such as dyslexia and schizophrenia. The genetic nature of this correlation is not understood. Recent discoveries have shown handedness is determined in part by the biological pathways that establish left/right (LR) body asymmetry during development. Cilia play a key role in this process, and candidate genes for dyslexia have also been recently shown to be involved in cilia formation. Defective cilia result not only in LR body asymmetry phenotypes but also brain midline phenotypes such as an absent corpus callosum. These findings suggest that the mechanisms for establishing LR asymmetry in the body are reused for brain midline development, which in turn influences traits such as handedness and reading ability.

    Angelman syndrome (AS) is a severe genetic disorder caused by mutations or deletions of the maternally inherited UBE3A gene. UBE3A encodes an E3 ubiquitin ligase that is expressed biallelically in most tissues but is maternally expressed in almost all neurons. In this review, we describe recent advances in understanding the expression and function of UBE3A in the brain and the etiology of AS. We highlight current AS model systems, epigenetic mechanisms of UBE3A regulation, and the identification of potential UBE3A substrates in the brain. In the process, we identify major gaps in our knowledge that, if bridged, could move us closer to identifying treatments for this debilitating neurodevelopmental disorder. PMID:21592595

    Retinopathy of prematurity (ROP) is an eye disease caused by an alteration in retinal vasculogenesis that may lead to partial or complete vision loss with a harmful impact in terms of neurodevelopment. The purpose of the present study was to determine the neurodevelopment in patients with type i retinopathy of prematurity treated with intravitreal bevacizumab. Case series. The inclusion criteria were: patients with type I ROP treated with a dose of 0.625mg/0.025ml of intravitreal bevacizumab. Demographic data and comorbidities were documented. Neurodevelopment was evaluated with the screening test of the Bayley Scale of Infant Development (BSID) in all patients between 11 and 28 weeks of age. Seven patients were included in the study. Four patients showed normal neurodevelopment according to the overall scores of the BSID scale. The distribution of high risk for neurodevelopmental delay in the different areas evaluated were as follows: 3 patients presented it in the cognitive area, one in the receptive communication area, one in the expressive area, one in the fine motor skills and 3 patients in the gross motor skills area. In these case series, the majority of patients treated with intravitreal bevacizumab for ROP showed normal neurodevelopment scores. Copyright © 2016 Academia Mexicana de Cirugía A.C.

    The diuretic agent bumetanide has recently been put forward as a novel, promising treatment of behavioral symptoms in autism spectrum disorder (ASD) and related conditions. Bumetanide can decrease neuronal chloride concentrations and may thereby reinstate γ-aminobutyric acid (GABA)-ergic inhibition in patients with neurodevelopmental disorders. However, strategies to select appropriate candidates for bumetanide treatment are lacking. We hypothesized that a paradoxical response to GABA-enforcing agents such as benzodiazepines may predict the efficacy of bumetanide treatment in neurodevelopmental disorders. We describe a case of a 10-year-old girl with ASD, epilepsy, cortical dysplasia, and a 15q11.2 duplication who had exhibited marked behavioral arousal after previous treatment with clobazam, a benzodiazepine. We hypothesized that this response indicated the presence of depolarizing excitatory GABA and started bumetanide treatment with monitoring of behavior, cognition, and EEG. The treatment resulted in a marked clinical improvement in sensory behaviors, rigidity, and memory performance, which was substantiated by questionnaires and cognitive assessments. At baseline, the girl's EEG showed a depression in absolute α power, an electrographic sign previously related to ASD, which was normalized with bumetanide treatment. The effects of bumetanide on cognition and EEG seemed to mirror the "nonparadoxical" responses to benzodiazepines in healthy subjects. In addition, temporal lobe epilepsy and cortical dysplasia have both been linked to disturbed chloride homeostasis and seem to support our assumption that the observed paradoxical response was due to GABA-mediated excitation. This case highlights that a paradoxical behavioral response to GABA-enforcing drugs may constitute a framework for targeted treatment with bumetanide.

    Angelman Syndrome (AS) is a rare neurodevelopment disorder resulting from deficient expression or function of the maternally inherited allele of UBE3A gene. The aim of the study is to attempt at providing a detailed definition of neurodevelopmental profile in AS, with particular regard to motor, cognitive, communicative, behavioural and neurovisual, features by using standardized instruments. A total of ten subjects aged from 5 to 11 years (4 males and 6 females) with molecular confirmed diagnosis of AS (7 15q11.2-q13 deletion and 3 UBE3A mutation) were enrolled in our study. All of them underwent an assessment protocol including neurological and neurovisual examination and the evaluation of motor (Gross Motor Function Measure Scale), cognitive (Griffiths Mental Development Scale and Uzgiris-Hunt Scale); adaptive (Vineland Adaptive Behavioural Scale); communication (MacArthur-Bates Communicative Development Inventory and video-recordings children's verbal expression), behavioural aspects (IPDDAG Scale) and neurovisual aspects. All children presented motor function involvement. A severe cognitive impairment was detected with different profiles according to the test applied. In all cases, communicative disability (phonemic inventory, word/gesture comprehension and production) and symptoms of inattention disorder were revealed. Neurovisual impairment was characterized by refractive errors, fundus oculi anomalies, strabismus and/or oculomotor dysfunction. AS presents a complex neurodevelopmental profile in which several aspects play a negative role in global development leading to a severe functional impairment. Intellectual disability is not the only component because neurovisual functions and behavioural disorders may worsen the global function and are needed of specific rehabilitation programs.

Methods: A sample of 36 patients with early-onset schizophrenia spectrum psychosis was compared to a control sample of 36 patients with migraine. We assessed early childhood neurodevelopmental milestones using a modified version of the General Developmental Scale, general intellectual ability using the Wechsler Intelligence Scale for Children–Revised or Leiter International Performance Scale–Revised for patients with speech and language abnormalities, and neurological soft signs with specific regard to subtle motor impairment. Results: Subjects with early-onset psychosis had a higher rate of impaired social development (P=0.001, learning difficulties (P=0.04, enuresis (P=0.0008, a lower intelligence quotient (P<0.001, and subtle motor impairments (P=0.005 than control subjects. Conclusion: We suggest that neurodevelopment in early-onset psychosis is characterized by a global impairment of functional and adaptive skills that manifests from early childhood, rather than a delay or limitation in language and motor development. The current evidence is based on a small sample and should be investigated in larger samples in future research.

    MRI is an established investigation in the evaluation of neonates with suspected hypoxic-ischaemic encephalopathy (HIE). However, its role as a predictor of neurodevelopmental outcome remains complex. To establish reproducible simplified MR criteria and evaluate their role in predicting neurodevelopmental outcome in term neonates with HIE. Term neonates with suspected HIE had MRI at 7-10 days of age. MR scans were interpreted according to new simplified criteria by two radiologists blinded to the clinical course and outcome. The new simplified criteria allocated grade 1 to cases with no central and less than 10% peripheral change, grade 2 to those with less than 30% central and/or 10-30% peripheral area change, and grade 3 to those with more than 30% central or peripheral change. MRI changes were compared with clinical neurodevelopmental outcome evaluated prospectively at 1 year of age. Neurodevelopmental outcome was based upon the DQ score (revised Griffith's) and cerebral palsy on neurological assessment. Of 20 subjects, all those showing severe (grade 3) MR changes (35%) died or had poor neurodevelopmental outcome. Subjects with a normal MR scan or with scans showing only mild (grade 1) MR changes (55%) had normal outcomes. One subject showing moderate (grade 2) changes on MRI had a moderate outcome (5%), while another had an atypical pattern of MR changes with a normal outcome (5%). Assessment of full-term neonates with suspected HIE using the simplified MR criteria is highly predictive of neurodevelopmental outcome. (orig.)

    2017-05-01

    Full Text Available Background: The appropriate moment for clamping the umbilical cord is controversial. Immediate cord clamping (ICC is an item of active management of the third stage of labor (AMTSL. Unclamped umbilical cord may cause inconvenience in preterm neonates because they commonly need some levels of emergent services. Some studies revealed delayed cord clamping (DCC of preterm neonates results in better health conditions like lower rates of respiratory distress syndrome (RDS, less morbidities in labor room and lower risk of postpartum hemorrhage. The aim of the present study was to determine the effect of delayed umbilical cord clamping on premature neonatal outcomes. Materials and Methods: In this single‑center randomized control trial study, sixty premature neonates (gestational age ≤ 34 weeks were randomly assigned to ICC (cord clamped at 5–10 seconds or DCC (30–45 seconds groups and followed up in neonatal intensive care unit (NICU. Primary outcomes were 1st and 5th minute Apgar score, average of level of hematocrit after birth, intra ventricle hemorrhage and need some levels of resuscitation. Results: Differences in demographic characteristics were not statistically significant. After birth, neonates who had delayed clamping had significantly higher mean hematocrit after at 4-hour of birth (49.58+5.15gr/dl vs. 46.58+5.40gr/dlin DCC vs. ICC groups, respectively (P=0.031. Delayed cord clamping reduced the duration of need to nasal continues positive airway pressure (NCPAP (86.7% and 60.0% in ICC and DCC groups, respectively, P= 0.039. Attractively, the results showed lower incidence of clinical sepsis in delayed cord clamping neonates (53.3% vs. 23.3% in ICC and DCC groups, respectively, P=0.033. Conclusion: Prematurity complications might decrease by delay umbilical cord clamping which improve the hematocrit, duration of need to NCPAP and incidence of clinical sepsis. Furthermore, DCC may have no negative impact on neonatal resuscitation.

    Fetal survival is severely compromised when the amniotic membrane ruptures between 16 and 24 weeks of pregnancy. Reduced amniotic fluid levels are associated with poor lung development, whereas adequate levels lead to better perinatal outcomes. Restoring amniotic fluid by means of ultrasound-guided amnioinfusion (AI) may be of benefit in improving perinatal and long-term outcomes in children of pregnancies with this condition. The AI in preterm premature rupture of membranes (AMIPROM) pilot study was conducted to assess the feasibility of recruitment, the methods for conduct and the retention through to long-term follow-up of participants with very early rupture of amniotic membranes (between 16 and 24 weeks of pregnancy). It was also performed to assess outcomes and collect data to inform a larger, more definitive, clinical trial. A prospective, non-blinded randomised controlled trial. A computer-generated random sequence using a 1 : 1 ratio was used. Randomisation was stratified for pregnancies in which the amniotic membrane ruptured between 16(+0) and 19(+6) weeks' gestation and 20(+0) and 24(+0) weeks' gestation. The randomisation sequence was generated in blocks of four. Telephone randomisation and intention-to-treat analysis were used. Four UK hospital-based fetal medicine units - Liverpool Women's NHS Trust, St. Mary's Hospital, Manchester, Birmingham Women's NHS Foundation Trust and Wirral University Hospitals Trust. Women with confirmed preterm prelabour rupture of membranes between 16(+0) and 24(+0) weeks' gestation. Women with multiple pregnancies, resultant fetal abnormalities or obstetric indication for immediate delivery were excluded. Participants were randomly allocated to either serial weekly transabdominal AI or expectant management (Exp) until 37 weeks of pregnancy, if the deepest pool of amniotic fluid was < 2 cm. Short-term maternal, pregnancy and neonatal outcomes and long-term outcomes for the child were studied. Long-term respiratory

    Preterm birth can impact on child development. As seen previously, children born preterm present more behavioral and/or emotional problems than do full-term counterparts. In addition to gestational age, neonatal clinical status should be examined to better understand the differential impact of premature birth on later developmental outcomes. The aim of the present study was to systematically review empirical studies on the relationship between prematurity, neonatal health status, and behavioral and/or emotional problems in children. A systematic search of the PubMed, PsycINFO, Web of Science, and LILACS databases for articles published from 2009 to 2014 was performed. The inclusion criteria were empirical studies that evaluated behavioral and/or emotional problems that are related to clinical neonatal variables in children born preterm. Twenty-seven studies were reviewed. Results showed that the degree of prematurity and birth weight were associated with emotional and/or behavioral problems in children at different ages. Prematurity that was associated with neonatal clinical conditions (e.g., sepsis, bronchopulmonary dysplasia, and hemorrhage) and such treatments as corticoids and steroids increased the risk for these problems. The volume and abnormalities of specific brain structures also were associated with these outcomes. In conclusion, the neonatal health problems associated with prematurity present a negative impact on later child emotional and adapted behavior. © 2016 Michigan Association for Infant Mental Health.

    Full Text Available Morbidity and mortality, like a frequency of long-term unfavourable psychomotor developmental outcomes is in inverse relationship with gestational age and birth weight. Now scientists give attention to the risk factors — the infection, preeclampsia, smoking, etc., to look for prevention of premature birth. The outcome of premature baby depends on the birth weight; the methodof labor and the hospital technical support also have an influence. The frequency of neurological impairments — infantile cerebral palsy, visual and hearing disorders, and probability of severe bronchopulmonary dysplasia are also in inverse relationship with gestational age and birth weight. Last decade there are many scientists give attention to the cognitive deficit and behavior disorders in adolescents, born premature. Premature infants with extremely low birth weight have developmental disorders at 8-13%. Not all of cognitive and behavioral problems have symptoms in the first years of life, but have delayed unfavourable effects. The severity of cognitive deficit not always corresponds with structural impairments of brain, detected in functional studies of premature baby in the first year of life.

    Full Text Available Introduction: Premature ejaculation is the most common male sexual dysfunction leading to distress in many couples. Master and Johnson emphasized the concept of early learned experiences and Kaplan emphasized lack of sensory awareness. For treatment sex therapists mainly utilize start-stop and squeeze techniques as homework. Couples enter sex therapy with some cognitive distortions and beliefs about sex and sexuality. These beliefs are also named sexual myths. For some couples using techniques to challenge cognitive distortions and maladaptive beliefs about sex and sexuality can be used. In this paper by presenting a case we discussed how cognitive techniques can be used along with behaviour techniques with couples. Case: Presenting clients are five years married couple who are thirty and twenty nine years old respectively. They attended to the outpatient clinic with the request of the female client. Their main complaint was premature ejaculation. They were diagnosed premature ejaculation using clinical interview. In treatment besides start and stop technique, cognitive techniques were utilized to address dysfunctional beliefs about sexuality. Discussion: Premature ejaculation is a male sexual dysfunction that causes distress and intimacy problems between couples. Stop start and squeeze techniques were accepted as the choice of treatment but their effectiveness is questioned recently. Also cognitive distortions and maladaptive beliefs may hamper therapy progress. Besides that, behavioral techniques utilizing cognitive techniques to lessen the degree of dysfunctional beliefs about sex and sexuality may help the couple to overcome premature ejaculation and enhance sexual satisfaction and intimacy.

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

    To investigate prevalence of neurodevelopmental disorders in children with obesity and to compare body mass index (BMI) and metabolic profile in the children. Seventy-six children (37 girls, 39 boys) were consecutively recruited from a university outpatient clinic specialized in severe obesity. Neurodevelopmental disorders including attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and developmental coordination disorder (DCD) were assessed using interviews and questionnaires. Neurodevelopmental diagnoses were collected retrospectively in medical records. BMI ranged between 1.9 and 5.9 SDS and age between 5.1 and 16.5 years. In 13.2% and 18.4% ASD and ADHD was assigned, respectively. In addition, 25% screened positive for DCD, 31.6% had at least one neurodevelopmental disorder, and 18.4% had a parent who screened positive for adult ADHD. Girls with ASD/ADHD had higher BMI SDS than girls without neurodevelopmental disorder (P = 0.006). One third of children with obesity referred to specialist centers have a neurodevelopmental disorder including deviant motor skills, and these problems may deteriorate weight status. One fifth of the parents exhibit ADHD symptomatology which could partly explain the poor adherence by some families in obesity units. Future obesity therapy could benefit from incorporating a neurodevelopmental treatment approach. © 2016 The Obesity Society.

    Full Text Available Abstract Background This paper initially describes premature mortality by Aboriginality in South Australia during 1999 to 2006. It then examines how these outcomes vary across area level socio-economic disadvantage and geographic remoteness. Methods The retrospective, cross-sectional analysis uses estimated resident population by sex, age and small areas based on the 2006 Census, and Unit Record mortality data. Premature mortality outcomes are measured using years of life lost (YLL. Subsequent intrastate comparisons are based on indirect sex and age adjusted YLL results. A multivariate model uses area level socio-economic disadvantage rank, geographic remoteness, and an interaction between the two variables to predict premature mortality outcomes. Results Aboriginal people experienced 1.1% of total deaths but 2.2% of YLL and Aboriginal premature mortality rates were 2.65 times greater than the South Australian average. Premature mortality for Aboriginal and non-Aboriginal people increased significantly as area disadvantage increased. Among Aboriginal people though, a significant main effect for area remoteness was also observed, together with an interaction between disadvantage and remoteness. The synergistic effect shows the social gradient between area disadvantage and premature mortality increased as remoteness increased. Conclusions While confirming the gap in premature mortality rates between Aboriginal South Australians and the rest of the community, the study also found a heterogeneity of outcomes within the Aboriginal community underlie this difference. The results support the existence of relationship between area level socio-economic deprivation, remoteness and premature mortality in the midst of an affluent society. The study concludes that vertically equitable resourcing according to population need is an important response to the stark mortality gap and its exacerbation by area socio-economic position and remoteness.

    Fetal programming is a long-standing, but still evolving, concept that links exposures during pregnancy to the later development of disease in the offspring. A fetal programming effect has been considered within different endocrine axes and in relation to different maternal endocrine diseases. In this critical review, we describe and discuss the hypothesis of fetal programming by maternal thyroid dysfunction in the context of fetal brain development and neurodevelopmental disorders in the offspring. Thyroid hormones are important regulators of early brain development, and evidence from experimental and observational human studies have demonstrated structural and functional abnormalities in the brain caused by the lack or excess of thyroid hormone during fetal brain development. The hypothesis that such abnormalities introduced during early fetal brain development increase susceptibility for the later onset of neurodevelopmental disorders in the offspring is biologically plausible. However, epidemiological studies on the association between maternal thyroid dysfunction and long-term child outcomes are observational in design, and are challenged by important methodological aspects. © 2017 European Society of Endocrinology.

    Discussion: Premature ejaculation is a male sexual dysfunction that causes distress and intimacy problems between couples. Stop start and squeeze techniques were accepted as the choice of treatment but their effectiveness is questioned recently. Also cognitive distortions and maladaptive beliefs may hamper therapy progress. Besides that, behavioral techniques utilizing cognitive techniques to lessen the degree of dysfunctional beliefs about sex and sexuality may help the couple to overcome premature ejaculation and enhance sexual satisfaction and intimacy.

    Very premature infants born in the last century following the early days of post-neonatal intensive care have demonstrated an array of physical, emotional, and mental health problems as they approach their third and fourth decades. These outcomes have been well documented by several international investigators. However, there is a paucity of information on the personal perspectives of these individuals with regard to their own quality of life, their hopes and their fears. This article will focus on the objective information from the published literature and how it differs from the personal perspectives of former very premature infants. Crown Copyright © 2016.

  13. Prenatal and postnatal animal models of immune activation: relevance to a range of neurodevelopmental disorders.

    2012-10-01

    Epidemiological evidence has established links between immune activation during the prenatal or early postnatal period and increased risk of developing a range of neurodevelopment disorders in later life. Animal models have been used to great effect to explore the ramifications of immune activation during gestation and neonatal life. A range of behavioral, neurochemical, molecular, and structural outcome measures associated with schizophrenia, autism, cerebral palsy, and epilepsy have been assessed in models of prenatal and postnatal immune activation. However, the epidemiology-driven disease-first approach taken by some studies can be limiting and, despite the wealth of data, there is a lack of consensus in the literature as to the specific dose, timing, and nature of the immunogen that results in replicable and reproducible changes related to a single disease phenotype. In this review, we highlight a number of similarities and differences in models of prenatal and postnatal immune activation currently being used to investigate the origins of schizophrenia, autism, cerebral palsy, epilepsy, and Parkinson's disease. However, we describe a lack of synthesis not only between but also within disease-specific models. Our inability to compare the equivalency dose of immunogen used is identified as a significant yet easily remedied problem. We ask whether early life exposure to infection should be described as a disease-specific or general vulnerability factor for neurodevelopmental disorders and discuss the implications that either classification has on the design, strengths and limitations of future experiments.

    This study examines psychosocial functioning in children with neurodevelopmental disorders (NDDs) and/or externalizing behavior problems (EBPs) as compared to children with neither condition. The longitudinal sample, drawn from the Canadian National Longitudinal Survey of Children and Youth, included children who were 6 to 9 years old in Cycle 1 who were followed-up biennially in Cycles 2 and 3 (N = 3476). The associations between NDDs and/or EBPs, child and family socio-demographic characteristics and parenting behaviors (consistency and ineffective parenting), were examined across several measures of child psychosocial functioning: peer relationships, general self-esteem, prosocial behavior and anxiety-emotional problems. Children with NDDs, EBPs, and both NDDs and EBPs self-reported lower scores on general self-esteem. Children with NDDs and both NDDs and EBPs reported lower scores on peer relationships and prosocial behavior. Lastly, children with both NDDs and EBPs self-reported higher scores on anxiety-emotional behaviors. After considering family socio-demographic characteristics and parenting behaviors, these differences remained statistically significant only for children with both NDDs and EBPs. Child age and gender, household income and parenting behaviors were important in explaining these associations. Psychosocial functioning differs for children with NDDs and/or EBPs. Children with both NDDs and EBPs appear to report poorer psychosocial functioning compared to their peers with neither condition. However, it is important to consider the context of socio-demographic characteristics, parenting behaviors and their interactions to understand differences in children's psychosocial functioning. Implication for Rehabilitation: Practitioners may wish to consider complexity in child health by examining a comprehensive set of determinants of psychosocial outcomes as well as comorbid conditions, such as neurodevelopmental disorders (NDDs) and externalizing

    Large well-designed clinical efficacy and safety randomized clinical trials (RCTs) are required to achieve regulatory approval of new drug treatments. The objective of this article is to make recommendations for the criteria for defining and selecting the clinical trial study population, design and efficacy outcomes measures which comprise ideal premature ejaculation (PE) interventional trial methodology. Data on clinical trial design, epidemiology, definitions, dimensions and psychological impact of PE was reviewed, critiqued and incorporated into a series of recommendations for standardisation of PE clinical trial design, outcome measures and reporting using the principles of evidence based medicine. Data from PE interventional studies are only reliable, interpretable and capable of being generalised to patients with PE, when study populations are defined by the International Society for Sexual Medicine (ISSM) multivariate definition of PE. PE intervention trials should employ a double-blind RCT methodology and include placebo control, active standard drug control, and/or dose comparison trials. Ejaculatory latency time (ELT) and subject/partner outcome measures of control, personal/partner/relationship distress and other study-specific outcome measures should be used as outcome measures. There is currently no published literature which identifies a clinically significant threshold response to intervention. The ISSM definition of PE reflects the contemporary understanding of PE and represents the state-of-the-art multi-dimensional definition of PE and is recommended as the basis of diagnosis of PE for all PE clinical trials.

  3. Optimal oxygen saturation in premature infants

    2011-09-01

    Full Text Available There is a delicate balance between too little and too much supplemental oxygen exposure in premature infants. Since underuse and overuse of supplemental oxygen can harm premature infants, oxygen saturation levels must be monitored and kept at less than 95% to prevent reactive oxygen species-related diseases, such as retinopathy of prematurity and bronchopulmonary dysplasia. At the same time, desaturation below 80 to 85% must be avoided to prevent adverse consequences, such as cerebral palsy. It is still unclear what range of oxygen saturation is appropriate for premature infants; however, until the results of further studies are available, a reasonable target for pulse oxygen saturation (SpO2 is 90 to 93% with an intermittent review of the correlation between SpO2 and the partial pressure of arterial oxygen tension (PaO2. Because optimal oxygenation depends on individuals at the bedside making ongoing adjustments, each unit must define an optimal target range and set alarm limits according to their own equipment or conditions. All staff must be aware of these values and adjust the concentration of supplemental oxygen frequently.

  4. Genetic and Environmental Control of Neurodevelopmental Robustness in Drosophila.

    Directory of Open Access Journals (Sweden)

    David J Mellert

    Full Text Available Interindividual differences in neuronal wiring may contribute to behavioral individuality and affect susceptibility to neurological disorders. To investigate the causes and potential consequences of wiring variation in Drosophila melanogaster, we focused on a hemilineage of ventral nerve cord interneurons that exhibits morphological variability. We find that late-born subclasses of the 12A hemilineage are highly sensitive to genetic and environmental variation. Neurons in the second thoracic segment are particularly variable with regard to two developmental decisions, whereas its segmental homologs are more robust. This variability "hotspot" depends on Ultrabithorax expression in the 12A neurons, indicating variability is cell-intrinsic and under genetic control. 12A development is more variable and sensitive to temperature in long-established laboratory strains than in strains recently derived from the wild. Strains with a high frequency of one of the 12A variants also showed a high frequency of animals with delayed spontaneous flight initiation, whereas other wing-related behaviors did not show such a correlation and were thus not overtly affected by 12A variation. These results show that neurodevelopmental robustness is variable and under genetic control in Drosophila and suggest that the fly may serve as a model for identifying conserved gene pathways that stabilize wiring in stressful developmental environments. Moreover, some neuronal lineages are variation hotspots and thus may be more amenable to evolutionary change.

    Full Text Available The purpose of this study was to compare rates of participation for children (4–9 years of age with neurodevelopmental disorders (NDDs with and without externalizing behavior problems (EBPs with children without disability and to examine mediators of the relation between disability and physical activity participation. Data for this study were drawn from Cycle 7 (2006-07 of the Canadian National Longitudinal Survey of Children and Youth (NLSCY. The frequency of children’s participation in organized sports or physical activities varied depending on the child’s health condition with children with NDDs and both NDDs and EBPs participating least in organized sports or physical activities followed by children with EBPs only. In contrast, there were no statistically significant differences by health group for children’s participation in unorganized sports or physical activities. These differences remained even after controlling for the effects of other child and family sociodemographic characteristics, except for children with EBPs only. These findings highlight the importance of considering children’s primary and other existing health conditions as well as family sociodemographic characteristics in order to better understand the factors that influence participation in organized physical activities for children with disabilities.

    Two extant evolutionary models, biological sensitivity to context theory (BSCT) and differential susceptibility theory (DST), converge on the hypothesis that some individuals are more susceptible than others to both negative (risk-promoting) and positive (development-enhancing) environmental conditions. These models contrast with the currently dominant perspective on personal vulnerability and environmental risk: diathesis stress/dual risk. We review challenges to this perspective based on emerging theory and data from the evolutionary, developmental, and health sciences. These challenges signify the need for a paradigm shift in conceptualizing Person x Environment interactions in development. In this context we advance an evolutionary--neurodevelopmental theory, based on DST and BSCT, of the role of neurobiological susceptibility to the environment in regulating environmental effects on adaptation, development, and health. We then outline current thinking about neurogenomic and endophenotypic mechanisms that may underpin neurobiological susceptibility, summarize extant empirical research on differential susceptibility, and evaluate the evolutionary bases and implications of BSCT and DST. Finally, we discuss applied issues including methodological and statistical considerations in conducting differential susceptibility research; issues of ecological, cultural, and racial--ethnic variation in neurobiological susceptibility; and implications of differential susceptibility for designing social programs. We conclude that the differential susceptibility paradigm has far-reaching implications for understanding whether and how much child and adult development responds, for better and for worse, to the gamut of species-typical environmental conditions.

  7. Role of nucleosome remodeling in neurodevelopmental and intellectual disability disorders

    Directory of Open Access Journals (Sweden)

    Alberto J Lopez

    2015-04-01

    Full Text Available It is becoming increasingly important to understand how epigenetic mechanisms control gene expression during neurodevelopment. Two epigenetic mechanisms that have received considerable attention are DNA methylation and histone acetylation. Human exome sequencing and genome-wide association studies have linked several neurobiological disorders to genes whose products actively regulate DNA methylation and histone acetylation. More recently, a third major epigenetic mechanism, nucleosome remodeling, has been implicated in human developmental and intellectual disability disorders. Nucleosome remodeling is driven primarily through nucleosome remodeling complexes with specialized ATP-dependent enzymes. These enzymes directly interact with DNA or chromatin structure, as well as histone subunits, to restructure the shape and organization of nucleosome positioning to ultimately regulate gene expression. Of particular interest is the neuron-specific Brg1/hBrm Associated Factor (nBAF complex. Mutations in nBAF subunit genes have so far been linked to Coffin-Siris syndrome, Nicolaides-Baraitser syndrome, schizophrenia, and Autism Spectrum Disorder. Together, these human developmental and intellectual disability disorders are powerful examples of the impact of epigenetic modulation on gene expression. This review focuses on the new and emerging role of nucleosome remodeling in neurodevelopmental and intellectual disability disorders and whether nucleosome remodeling affects gene expression required for cognition independently of its role in regulating gene expression required for development.

    Full Text Available Background/Aim. Hemodynamic stress is the leading cause of acute renal failure (ARF in premature neonates. Incidence of ARF in this population is between 8 and 24%. The aim of this study was to determine the frequency of presence of ARF in premature neonates, as well as its impact on their survival. Methods. A retrospective study of 114 premature neonates [(gestational age, GA less than 37 gestation weeks (gw] admitted to the Intensive Care Unit (ICU at the Pediatric Clinic, Institute of Child and Youth Healthcare of Vojvodina in 2007 was conducted. Serum creatinine, urea and bilirubine were determined on the 3rd day of life in 65 newborns who met inclusion criteria. ARF was diagnosed in 16 newborns (n=16/65; 25%. Results. The premature neonates with ARF had significantly lower GA [<28 gw - 8/16 (50% vs. 5/49 (10%; p < 0.05], birth weight (BW (1 265 g vs. 1615 g; p < 0.05 and systolic blood pressure (43.37 mm Hg vs. 52.7 mmHg; p < 0.05 than ones without ARF. Non-olyguric ARF was diagnosed in 62% of newborns with ARF (n=10/16, while the rest had the olyguric type (n = 6/16; 38%. Twenty-five percent of premature neonates with ARF (n = 4/16 died in contrast to 10% of premature neonates without ARF (n = 5/49. ARF was treated conservatively in all but 3 cases when peritoneal dialysis was performed. Renal function has recovered completely in all of the survivors. In order to determine their predictivity in relation to ARF, following parameters were analyzed: GA, BW < 1 500 g, presence of concomitant sepsis and intracranial hemorrhage grade III/IV. BW < 1 500 g demonstrated the highest sensitivity (se 0.75, while GA < 28 gw, sepsis and intracranial hemorrhage grade III/IV showed high specificity (sp = 0.90, 0.89 0.88, respectively. Conclusion. Acute renal failure frequently occurs in population of premature neonates and requires meticulous fluid and electrolyte balance, especially in the case of low birth weight and extreme immaturity.

    Full Text Available The membranes surrounding the amniotic cavity are composed from amnion and chorion, tightly adherent layers which are composed of several cell types, including epithelial cells, trophoblasts cells and mesenchyme cells, embedded in a collagenous matrix. They retain amniotic fluid, secret substances into the amniotic fluid, as well as to the uterus and protect the fetus against upward infections from urogenital tract. Normally, the membranes it breaks during labor. Premature rupture of the amniotic sac (PRAS is defined as rupture of membranes before the onset of labor. Premature rupture of the fetal membrane, which occurs before 37 weeks of gestation, usually, refers to preterm premature rupture of membranes. Despite advances in the care period, premature rupture of membranes and premature rupture of membranes preterm continue to be regarded as serious obstetric complications. On the term 8% - 10% of pregnant women have premature rupture of membranes; these women are at increased risk of intrauterine infections, where the interval between membrane rupture and expulsion is rolled-over. Premature rupture of membranes preterm occurs in approximately 1% of all pregnancies and is associated with 30% -40% of preterm births. Thus, it is important to identify the cause of pre-term birth (after less than 37 completed weeks of "gestation" and its complications, including respiratory distress syndrome, neonatal infection and intraventricular hemorrhage. Objectives: the development of the protocol of the clinical trial on patients with impending preterm birth, study clinical and statistical on the socio-demographic characteristics of patients with imminent preterm birth; clinical condition of patients and selection of cases that could benefit from the application of interventional therapy; preclinical investigation (biological and imaging of patients with imminent preterm birth; the modality therapy; clinical investigation of the effectiveness of short

    In children born prematurely, impairment of vision due to damage to the brain is more common than due to retinopathy of prematurity. Yet, the diagnosis of cerebral visual impairment may be missed. The subject of cerebral visual impairment in children is reviewed in order to explain and draw attention to the types of visual deficits and behaviours that may result as a sequel to premature birth. A wide range of sources of data has been employed to assemble this overview. The principal reference source is PubMed. The material presented highlights the origin and range of visual deficits that result from damage to the brain, related to premature birth. Deficits of primary visual functions, perceptual dysfunction, simultanagnostic visual disorders and impaired visual guidance of movement (optic ataxia), as well as disorders of visual attention and memory, can occur in a variety of combinations and degrees. The resulting behavioural outcomes are described. Identification and characterisation of impaired vision, due to prematurity associated damage to the brain, are essential. This is required so as to ensure that affected children are not inappropriately disadvantaged on account of the diagnosis being missed or inadequately acted upon, but instead, they are managed optimally, both at home and at school, so that their development is enhanced to the greatest advantage.

    Evolving technology and scientific advancement have increased the chances of survival of the extremely premature baby; however, such survival can be associated with some severe long-term morbidities. The research investigates the caregiving and ethical dilemmas faced by neonatal nurses when caring for extremely premature babies (defined as ≤24 weeks' gestation). This article explores the issues arising for neonatal nurses when they considered the philosophical question of 'what if it was me and my baby', or what they believed they would do in the hypothetical situation of going into premature labour and delivering an extremely premature baby. Data were collected via a questionnaire to Australian neonatal nurses and semi-structured interviews with 24 neonatal nurses in New South Wales, Australia. Relevant ethical approvals have been obtained by the researchers. A qualitative approach was used to analyse the data. The theme 'imagined futures' was generated which comprised three sub-themes: 'choice is important', 'not subjecting their own baby to treatment' and 'nurses and outcome predictions'. The results offer an important and unique understanding into the perceptions of nursing staff who care for extremely premature babies and their family, see them go home and witness their evolving outcomes. The results show that previous clinical and personal experiences led the nurses in the study to choose to have the belief that if in a similar situation, they would choose not to have their own baby resuscitated and subjected to the very treatment that they provide to other babies. The theme 'imagined futures' offers an overall understanding of how neonatal nurses imagine what the life of the extremely premature baby and his or her family will be like after discharge from neonatal intensive care. The nurses' past experience has led them to believe that they would not want this life for themselves and their baby, if they were to deliver at 24 weeks' gestation or less. © The

    To characterize administration of sedatives, analgesics, and paralytics in a large cohort of mechanically ventilated premature infants. Retrospective cohort study including all infants neonatal intensive care units from 1997 to 2012. The primary outcome is the proportion of mechanically ventilated days in which infants were administered drugs of interest. Multivariable logistic regression was used to evaluate the predictors of administration of drugs of interest. We identified 85 911 mechanically ventilated infants. Infants received a drug of interest (opioids, benzodiazepines, other sedatives, and paralytics) on 433 587/1 305 413 (33%) of mechanically ventilated infant days. The administration of opioids increased during the study period from 5% of infant days in 1997 to 32% in 2012. The administration of benzodiazepines increased during the study period from 5% of infant days in 1997 to 24% in 2012. Use of paralytics and other drugs remained ≤1% throughout the study period. Predictors of drug administration included younger GA, small for GA status, male sex, presence of a major congenital anomaly, older postnatal age at intubation, exposure to high-frequency ventilation, exposure to inotropes, more recent year of discharge, and neonatal intensive care unit site. Administration of opioids and benzodiazepines in mechanically ventilated premature infants increased over time. Because infant characteristics were unchanged, site-specific differences in practice likely explain our observations. Increased administration over time is concerning given limited evidence of benefit and potential for harm. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Background: Premature rupture of membrane (PROM is one of the common complications of pregnancy that has major impact on fetal and neonatal outcome. It is the commonest clinical event where a normal pregnancy becomes suddenly a high-risk one for mother and fetus or neonate. Objective: The study was undertaken to investigate whether raised fibronectin level in vaginal fluid may indicate premature rupture of membrane. Materials and Methods: This cross sectional study was conducted in the department of Obstetrics and Gynecology in Sir Salimullah Medical College & Mitford Hospital, Dhaka during the period of January 2006 to December 2007. A total of 114 pregnant women with gestational age 28th week up to 40th week were included. Sixty were PROM (Group I and 54 were non-PROM (Group II subjects. Fibronectin in vaginal fluid was measured by an immunochemical reaction by nephelometer. Statistical analysis was done by SPSS version 10.0. Results: The PROM patients had significantly higher concentration of fibronectin (225.77 ± 115.18 ng/mL compared to that in non-PROM subjects (8.04 ± 16.17 ng/mL (p < 0.001. Conclusion: It can be concluded that in cases of unequivocal rupture or intactness of the membranes, the result of the fibronectin test corresponds well with the clinical situation. So fibronectin is a sensitive test for detection of amniotic fluid in the vagina.

    The introduction of anti-vascular endothelial growth factor (VEGF) agents has stimulated considerable reexamination of treatment strategies for the management of retinopathy of prematurity (ROP). Herein we summarize and review evolving concepts and provide a personal perspective on clinical management today and future directions of treatment. Literature review. To synthesize the evolving management concepts for diagnosis and treatment of retinopathy of prematurity and to provide interpretation and perspective on current emerging therapies. Although initial treatment strategies focused on ablative therapy for threshold ROP, earlier treatment for type 1 or pre-threshold disease has been found to decrease unfavorable visual and structural outcomes. Vascular endothelial growth factor has emerged as a significant contributor to retinal-vascular diseases in the previous 2 decades. The potential role of anti-VEGF treatment for type 1 ROP has become a focus in recent years, but the protracted recurrence of disease and unknown adverse ocular and systemic effects have caused concern from some clinicians. In addition, the use of telemedicine technologies may provide the ability to screen remote areas with a shortage of ROP providers, thereby reducing the burden of disease. The diagnosis and management of ROP has changed over the past 40 years; the role of anti-VEGF therapy remains to be established in current treatment strategies. Screening for initial disease and progression will likely be impacted by the increasing prevalence of telemedicine and relative shortage of clinicians. Published by Elsevier Inc.

    The arrival of the Journal's 175th anniversary occurs at a time of recent advances in research, providing an ideal opportunity to present a neurodevelopmental roadmap for understanding, preventing, and treating psychiatric disorders. Such a roadmap is particularly relevant for early-childhood-onset neurodevelopmental conditions, which emerge when experience-dependent neuroplasticity is at its peak. Employing a novel developmental specification approach, this review places recent neurodevelopmental research on early childhood disruptive behavior within the historical context of the Journal. The authors highlight irritability and callous behavior as two core exemplars of early disruptive behavior. Both phenotypes can be reliably differentiated from normative variation as early as the first years of life. Both link to discrete pathophysiology: irritability with disruptions in prefrontal regulation of emotion, and callous behavior with abnormal fear processing. Each phenotype also possesses clinical and predictive utility. Based on a nomologic net of evidence, the authors conclude that early disruptive behavior is neurodevelopmental in nature and should be reclassified as an early-childhood-onset neurodevelopmental condition in DSM-5. Rapid translation from neurodevelopmental discovery to clinical application has transformative potential for psychiatric approaches of the millennium.

    The prefrontal cortex (PFC), seat of the highest-order cognitive functions, constitutes a conglomerate of highly specialized brain areas and has been implicated to have a role in the onset and installation of various neurodevelopmental disorders. The development of a properly functioning PFC is directed by transcription factors, guidance cues and other regulatory molecules and requires the intricate and temporal orchestration of a number of developmental processes. Disturbance or failure of any of these processes causing neurodevelopmental abnormalities within the PFC may contribute to several of the cognitive deficits seen in patients with neurodevelopmental disorders. In this review, we elaborate on the specific processes underlying prefrontal development, such as induction and patterning of the prefrontal area, proliferation, migration and axonal guidance of medial prefrontal progenitors, and their eventual efferent and afferent connections. We furthermore integrate for the first time the available knowledge from genome-wide studies that have revealed genes linked to neurodevelopmental disorders with experimental molecular evidence in rodents. The integrated data suggest that the pathogenic variants in the neurodevelopmental disorder-associated genes induce prefrontal cytoarchitectonical impairments. This enhances our understanding of the molecular mechanisms of prefrontal (mis)development underlying the four major neurodevelopmental disorders in humans, that is, intellectual disability, autism spectrum disorders, attention deficit hyperactivity disorder and schizophrenia, and may thus provide clues for the development of novel therapies.

    The purpose of this longitudinal qualitative descriptive study was to explore American Indian mothers' perceptions of parenting their premature infants over their first year of life in the context of their culture, including the birth and hospitalization experience. A convenience sample of 17 American Indian 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 American Indian culture appear to be important in having a premature infant in the NICU and in parenting a premature infant. We recommend that health care providers deliver culturally appropriate care that fully supports American Indian mothers and their premature infants. © The Author(s) 2015.

    This study aims to examine the relationship between indicators of prematurity and children's cognitive and behavioral school readiness in a nationally representative sample and to investigate whether typically occurring preschool enrollment moderates this relationship, particularly for children from disadvantaged families in Australia. The Longitudinal Study of Australian Children is a nationally representative prospective sample of two cohorts of children with sequentially obtained indicators of child health and developmental outcomes. We analyzed information on 8060 children aged 4-5 years who had complete data on birth weight, gestational age, prenatal risks, social factors, and cognitive and behavioral outcomes of school readiness. Multivariate regressions were used to relate three indicators of prematurity (low birth weight, preterm birth, and small for gestational age) to cognitive and behavioral school readiness. Children born preterm, small for gestational age, or with low birth weight have significantly lower cognitive school readiness after controlling for social factors and prenatal risks. None of the premature indicators were associated with behavioral school readiness. All children benefited from attending preschool. Yet, preschool enrollment did not moderate the relationship between prematurity and school readiness. The only exception is for small for gestational age survivors with low educated mothers. Preschool enrollment was associated with an increase in cognitive school readiness skills. Prematurity was associated with lower cognitive school readiness skills. Typical occurring preschool did not eliminate this association. Findings suggest that simply expanding the preschool enrollment is inadequate to address the developmental needs of premature children from disadvantaged backgrounds. © 2013.

    We sought to compare neonatal outcome in cases of uncomplicated preterm premature rupture of membranes (PPROM) (ie, no evidence of clinical chorioamnionitis, placental abruption, or fetal distress) with that of spontaneous preterm deliveries (PTDs) and to determine the effect of the latency period. The study group included women with PPROM at gestational age 28⁰(/)⁷-33⁶(/)⁷ weeks (n = 488). Neonatal outcome was compared with a matched control group of women with spontaneous PTD (n = 1464). Neonates in the uncomplicated PPROM group were at increased risk for composite adverse outcome (53.7% vs 42.0%; P 7 days, oligohydramnios, male fetus, and nulliparity. Consultation regarding prematurity-related morbidity in infants exposed to uncomplicated PPROM cannot be extrapolated from PTDs and should be stratified by the duration of the latency period and the other risk factors identified in the current study.

    A unifying model of autism causation remains elusive, and thus well-designed explanatory models are needed to develop appropriate therapeutic and preventive interventions. This essay argues that autism is not a static disorder, but rather an ongoing process. We discuss the link between preterm birth and autism and briefly review the evidence supporting the link between immune system characteristics and both prematurity and autism. We then propose a causation process model of autism etiology and pathogenesis, in which both neurodevelopment and ongoing/prolonged neuroinflammation are necessary pathogenetic component mechanisms. We suggest that an existing model of sufficient cause and component causes can be interpreted as a mechanistic view of etiology and pathogenesis and can serve as an explanatory model for autism causal pathways.

    Objective Angelman syndrome (AS) is a neurodevelopmental disorder caused by a deletion on chromosome 15, uniparental disomy (UPD), imprinting defect, or UBE3A mutation. It is characterized by intellectual disability with minimal speech and certain behavioral characteristics. We used standardized measures to characterize the developmental profile and to analyze genotype-phenotype correlations in AS. Method The study population consisted of 92 children, between 5 months and 5 years of age, enrolled in a Natural History Study. Each participant was evaluated using the Bayley Scales of Infant and Toddler Development (Third Edition) (BSID-III), the Vineland Adaptive Behavior Scales (Second Edition) (VABS-II), and the Aberrant Behavior Checklist. Results 74% had a deletion and 26% had UPD, an imprinting defect or a UBE3A mutation (“non-deletion”). The mean±standard deviation (SD) BSID-III cognitive scale developmental quotient (DQ) was 40.5±15.5. Participants with deletions were more developmentally delayed than the non-deletion participants in all BSID-III domains except in expressive language skills. The cognitive DQ was higher than the DQ in each of the other domains, and the receptive language DQ was higher than the expressive language DQ. In the VABS-II, deletion participants had weaker motor and language skills than the non-deletion participants. Conclusion Children with AS have a distinct developmental and behavioral profile; their cognitive skills are stronger than their language and motor skills, and their receptive language skills are stronger than expressive language skills. Developmental outcomes are associated with genotype, with deletion patients having worse outcomes than non-deletion patients. PMID:20729760

    Alternating hemiplegia of childhood is a predominantly sporadic neurodevelopmental syndrome of uncertain etiology. In more than 3 decades since its description, little progress has been made in understanding its etiology or in identifying effective treatments. In 1998, in collaboration with the Alternating Hemiplegia of Childhood Foundation, an international registry was established to help document clinical outcomes and promote research efforts. We present phenotypic data on 103 patients who met existing diagnostic criteria for alternating hemiplegia of childhood. Although some of these subjects may have been included in previously published reviews, our focus was directed toward the earliest manifestations of symptoms and evolution of features over time. Data sources included written questionnaires, face-to-face and telephone interviews, clinical examination, and medical charts. Characteristics of disease onset, medical comorbidities, episode triggers, diagnostic workup, and treatment are presented. Paroxysmal eye movements were the most frequent early symptom, manifesting in the first 3 months of life in 83% of patients. Hemiplegic episodes appeared by 6 months of age in 56% of infants. Background slowing shown by electroencephalography during typical paroxysmal events, including hemiplegic, tonic, or dystonic episodes was frequent (21 of 42 cases). Distinct convulsive episodes with altered consciousness believed to be epileptic in nature were reported in 41% of patients. Ataxia (96%) and cognitive impairment (100%) were frequent nonepisodic symptoms. Empiric pharmacologic treatment approaches offered little benefit in most subjects and resulted in adverse effects in 20% of patients. Prolonged episodes were completely or temporarily aborted during sleep in all subjects. This descriptive analysis of a large cohort of children indicates that paroxysmal ocular movements are an early, highly suggestive symptom, followed by paroxysmal episodes of focal dystonia or

    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.

    2016-06-01

    Bipolar disorder (BP) is a chronic neuropsychiatric condition characterized by pathological fluctuations in mood from mania to depression. Adoption, twin and family studies have consistently identified a significant hereditary component to BP, yet there is no clear genetic event or consistent neuropathology. BP has been suggested to have a developmental origin, although this hypothesis has been difficult to test since there are no viable neurons or glial cells to analyze, and research has relied largely on postmortem brain, behavioral and imaging studies, or has examined proxy tissues including saliva, olfactory epithelium and blood cells. Neurodevelopmental factors, particularly pathways related to nervous system development, cell migration, extracellular matrix, H3K4 methylation, and calcium signaling have been identified in large gene expression and GWAS studies as altered in BP. Recent advances in stem cell biology, particularly the ability to reprogram adult somatic tissues to a pluripotent state, now make it possible to interrogate these pathways in viable cell models. A number of induced pluripotent stem cell (iPSC) lines from BP patient and healthy control (C) individuals have been derived in several laboratories, and their ability to form cortical neurons examined. Early studies suggest differences in activity, calcium signaling, blocks to neuronal differentiation, and changes in neuronal, and possibly glial, lineage specification. Initial observations suggest that differentiation of BP patient-derived neurons to dorsal telencephalic derivatives may be impaired, possibly due to alterations in WNT, Hedgehog or Nodal pathway signaling. These investigations strongly support a developmental contribution to BP and identify novel pathways, mechanisms and opportunities for improved treatments. Copyright © 2015 Elsevier Inc.

    Neurodevelopmental origins of functional variation in older age are increasingly being acknowledged, but identification of how early factors impact human brain and cognition throughout life has remained challenging. Much focus has been on age-specific mechanisms affecting neural foundations of cognition and their change. In contrast to this approach, we tested whether cerebral correlates of general cognitive ability (GCA) in development could be extended to the rest of the lifespan, and whether early factors traceable to prenatal stages, such as birth weight and parental education, may exert continuous influences. We measured the area of the cerebral cortex in a longitudinal sample of 974 individuals aged 4-88 y (1,633 observations). An extensive cortical region was identified wherein area related positively to GCA in development. By tracking area of the cortical region identified in the child sample throughout the lifespan, we showed that the cortical change trajectories of higher and lower GCA groups were parallel through life, suggesting continued influences of early life factors. Birth weight and parental education obtained from the Norwegian Mother-Child Cohort study were identified as such early factors of possible life-long influence. Support for a genetic component was obtained in a separate twin sample (Vietnam Era Twin Study of Aging), but birth weight in the child sample had an effect on cortical area also when controlling for possible genetic differences in terms of parental height. Our results provide novel evidence for stability in brain-cognition relationships throughout life, and indicate that early life factors impact brain and cognition for the entire life course.

    Paul MacLean has investigated integrated brain functioning through selected brain lesions in animals that disturb circuits necessary for complex behaviors, such as social displays. MacLean is unique in his comparative neurobehavioral approach that emphasizes the evolutionary origins of parenting and social behaviors and the implications of brain changes in the evolution from reptiles (social displays) to mammals (nursing, audiovocal communication, play) to man (self-awareness, intentionality, social context) that link affect and cognition. Subjectively, how "looking with feeling toward others," the basic element in empathy, evolved has been a central concern of his. Neuroimaging studies of social cognition, mother-infant communication, moral behavior, forgiveness, and trust are consistent with particular brain systems being activated in cooperative social behaviors. The identification of mirror neurons is pertinent to MacLean's model of isopraxis and studies of thalamocortical resonances may be pertinent to his neurobehavioral models. Studies of behavioral phenotypes in human neurodevelopmental disorders are consistent with MacLean's model of brain circuits being linked to complex behaviors during development. In autistic disorder, the behavioral phenotype involves disrupted social communication, deviant imaginative play, and motor stereotypies. In Lesch-Nyhan syndrome (LNS), self-injury occurs in individuals with normal sensory systems intact who require and request physical restraint to prevent self-injury; they ask for assistance from others to prevent them from harming themselves. Autism involves the lack of subjective awareness of others intentions and LNS involves a failure in self-regulation and self-control of self-injurious behavior. MacLean's models laid the groundwork for studies focused on understanding brain functioning in these conditions.

    The use of prescription medication to augment cognitive or affective function in healthy persons-or neuroenhancement-is increasing in adult and pediatric populations. In children and adolescents, neuroenhancement appears to be increasing in parallel to the rising rates of attention-deficit disorder diagnoses and stimulant medication prescriptions, and the opportunities for medication diversion. Pediatric neuroenhancement remains a particularly unsettled and value-laden practice, often without appropriate goals or justification. Pediatric neuroenhancement presents its own ethical, social, legal, and developmental issues, including the fiduciary responsibility of physicians caring for children, the special integrity of the doctor-child-parent relationship, the vulnerability of children to various forms of coercion, distributive justice in school settings, and the moral obligation of physicians to prevent misuse of medication. Neurodevelopmental issues include the importance of evolving personal authenticity during childhood and adolescence, the emergence of individual decision-making capacities, and the process of developing autonomy. This Ethics, Law, and Humanities Committee position paper, endorsed by the American Academy of Neurology, Child Neurology Society, and American Neurological Association, focuses on various implications of pediatric neuroenhancement and outlines discussion points in responding to neuroenhancement requests from parents or adolescents. Based on currently available data and the balance of ethics issues reviewed in this position paper, neuroenhancement in legally and developmentally nonautonomous children and adolescents without a diagnosis of a neurologic disorder is not justifiable. In nearly autonomous adolescents, the fiduciary obligation of the physician may be weaker, but the prescription of neuroenhancements is inadvisable because of numerous social, developmental, and professional integrity issues.

    Whole exome sequencing (WES) is well established in research and is now being introduced into clinically indicated diagnostics (so-called clinical exomes). We evaluated the diagnostic yield and clinical implications of WES in 72 patients from 60 families with undiagnosed neurodevelopmental disorders (NDD), neurometabolic disorders, and dystonias. Pathogenic or likely pathogenic variants leading to a molecular diagnosis could be identified in 21 of the 60 families (overall 35%, in 36% of patients with NDD, in 43% of patients with neurometabolic disorders, in 25% of patients with dystonias). In one family two coexisting autosomal recessive diseases caused by homozygous pathogenic variants in two different genes were diagnosed. In another family, a homozygous frameshift variant in STRADA was found to cause a severe NDD with early onset epilepsy, brain anomalies, hypotonia, heart defect, nephrocalcinosis, macrocephaly and distinctive facies so far designated as PMSE (polyhydramnios, megalencephaly, symptomatic epilepsy) syndrome. In 7 of the 21 families with a molecular diagnosis the pathogenic variants were only identified by clinical follow-up, manual reevaluation of the literature, a change of filter setting, and/or reconsideration of inheritance pattern. Most importantly, clinical implications included management changes in 8 cases and impact on family planning in 20 families with a molecular diagnosis. This study shows that reevaluation and follow-up can improve the diagnostic rate and that WES results have important implications on medical management and family planning. Furthermore, we could confirm STRADA as a gene associated with syndromic ID but find it questionable if the current designation as PMSE depicts the most important clinical features.

    Periventricular leucomalacia (PVL) and parenchymal venous infarction complicating germinal matrix/intraventricular haemorrhage have long been recognised as the two significant white matter diseases responsible for the majority of cases of cerebral palsy in survivors of preterm birth. However, more recent studies using magnetic resonance imaging to assess the preterm brain have documented two new appearances, adding to the spectrum of white matter disease of prematurity: punctate white matter lesions, and diffuse excessive high signal intensity (DEHSI). These appear to be more common than PVL but less significant in terms of their impact on individual neurodevelopment. They may, however, be associated with later cognitive and behavioural disorders known to be common following preterm birth. It remains unclear whether PVL, punctate lesions, and DEHSI represent a continuum of disorders occurring as a result of a similar injurious process to the developing white matter. This review discusses the role of MR imaging in investigating these three disorders in terms of aetiology, pathology, and outcome. (orig.)

    Preterm delivery occurs in approximately 12% of all births in the United States and is a major factor that contributes to perinatal morbidity and mortality (1, 2). Preterm premature rupture of membranes (PROM) complicates approximately 3% of all pregnancies in the United States (3). The optimal approach to clinical assessment and treatment of women with term and preterm PROM remains controversial. Management hinges on knowledge of gestational age and evaluation of the relative risks of delivery versus the risks of expectant management (eg, infection, abruptio placentae, and umbilical cord accident). The purpose of this document is to review the current understanding of this condition and to provide management guidelines that have been validated by appropriately conducted outcome-based research when available. Additional guidelines on the basis of consensus and expert opinion also are presented.

    To identify patterns of sleep-wake transitions in the neonatal period that might differentiate premature infants who would show better or worse outcomes in multiple developmental domains across the first 5 years of life. Participants were 143 low birth weight premature infants (mean birth weight: 1482 g; mean gestational age [GA]: 31.82 weeks). Sleep states were observed at a GA of 37 weeks in 10-second epochs over 4 consecutive evening hours and were analyzed through mathematical clustering. Neurobehavioral maturation was evaluated with the Neonatal Behavior Assessment Scale at discharge, emotional regulation was assessed during infant-mother and infant-father interactions at 3 and 6 months, cognitive development was measured at 6, 12, and 24 months, and verbal IQ, executive functions, and symbolic competence were tested at 5 years. Three types of state-transition patterns were identified, and no differences in birth weight, GA, or medical risk between the 3 groups were found. Infants whose sleep-state transitions were mainly characterized by shifts between quiet sleep and wakefulness exhibited the best development, including greater neonatal neuromaturation, less negative emotionality, better cognitive development, and better verbal, symbolic, and executive competences at 5 years. In comparison, infants who cycled mainly between states of high arousal, such as active sleep and cry, or between short episodes of active and quiet sleep showed poorer outcomes. Defining sleep organization on the basis of transitions between states proved useful for identifying risk and resilience indicators in neonatal behavior to predict trajectories of neurobehavioral, emotional, and cognitive growth.

    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.

    Although premature ejaculation is the most common ejaculation problem, it is poorly understood and currently has no standard definition.(1) Typically, it involves reduced time to ejaculation, inability to control or delay ejaculation and associated distress.(1-5) Treatments that have been assessed include psychosexual counselling, antidepressants (e.g. selective serotonin reuptake inhibitors), phosphodiesterase type-5 inhibitors, tramadol and topical anaesthetic agents (e.g. lidocaine/prilocaine cream). A new formulation (cutaneous spray) of lidocaine/prilocaine (Fortacin-Plethora Solutions Ltd.) was launched in the UK in November 2016 for the treatment of primary premature ejaculation.(6,7) Here, we consider the evidence for lidocaine/prilocaine spray and whether it has a role in the treatment of premature ejaculation.

    Bronchopulmonary dysplasia (BPD) is the most common chronic respiratory disease in premature infants. BPD was first described by Northway in 1967 as a chronic respiratory condition that developed in premature infants exposed to mechanical ventilation and high oxygen supplementation. DBP is currently defined by the need for supplemental oxygen at 28 days of life (mild BPD) and at the 36 weeks of post-menstrual age (moderate and severe BPD). With the advances of neonatal care, epidemiological characteristics and mechanisms of the disease as well as pathological characteristics and clinical course have profoundly changed within the last two decades, but still no effective curative treatment exists and BPD continue to occur among 10 to 20% of premature infants. Furthermore, BPD is a significant source of respiratory and neuro-cognitive morbidities. Thus, its treatment makes a considerable demand on health services. Regarding its pathophysiological mechanisms, it is now established that BPD is a complex disease combining genetic susceptibility and environmental injuries. The identification of genetic variants involved in BPD is a potential source of innovative development in terms of diagnosis and treatment. Indeed, no curative or effective prophylactic therapeutic exists and BPD treatment is currently symptomatic. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Full Text Available 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.

    The overarching goal of this review is to compare and contrast the cognitive-behavioral features of fragile X syndrome (FraX) and Williams syndrome and to review the putative neural and molecular underpinnings of these features. Information is presented in a framework that provides guiding principles for conceptualizing gene-brain-behavior associations in neurodevelopmental disorders. Abnormalities, in particular cognitive-behavioral domains with similarities in underlying neurodevelopmental correlates, occur in both FraX and Williams syndrome including aberrant frontostriatal pathways leading to executive function deficits, and magnocellular/dorsal visual stream, superior parietal lobe, inferior parietal lobe, and postcentral gyrus abnormalities contributing to deficits in visuospatial function. Compelling cognitive-behavioral and neurodevelopmental contrasts also exist in these two disorders, for example, aberrant amygdala and fusiform cortex structure and function occurring in the context of contrasting social behavioral phenotypes, and temporal cortical and cerebellar abnormalities potentially underlying differences in language function. Abnormal dendritic development is a shared neurodeve
