Recent data suggest recovery of language systems but persistent structural abnormalities in the prematurely born. We tested the hypothesis that subjects who were born prematurely develop alternative networks for processing language. Subjects who were born prematurely (n = 22; 600-1250 g birth weight), without neonatal brain injury on neonatal…

Hypothesis/introduction Preeclampsia is associated with alterations in the maternal renin–angiotensin–aldosterone system (RAAS), increased blood pressure (BP), and cardiovascular risk in the offspring. We hypothesized that preeclampsia is associated with alterations in the RAAS in the offspring that persist into adolescence. Materials and methods We compared components of the circulating (n = 111) and renal (n = 160) RAAS in adolescents born prematurely with very low birth weight (VLBW) of preeclamptic (PreE) and normotensive (NoHTN) pregnancies. Multivariable linear regression was used to evaluate potential confounding and intermediate variables. Analyses were stratified by sex. Results Adjusting for race and antenatal steroid exposure, male offspring of PreE mothers had higher circulating aldosterone than those of NoHTN mothers (adjusted mean difference = 109; 95% confidence limits: −9, 227 pmol/L). Further adjustment for current BMI attenuated this difference (adjusted mean difference: 93; 95% confidence limits: −30, 215 pmol/L). Conclusion Among male preterm VLBW infants, maternal preeclampsia is associated with increased circulating aldosterone level in adolescence, which appears to be mediated in part by higher BMI.

Children born very prematurely are at risk of low average IQ and behaviour difficulties throughout childhood and adolescence. Associations among preterm birth, IQ and behaviour have been reported; however, the nature of the relationship among these outcomes is not fully understood. Some studies have proposed that the consequences of preterm birth,…

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

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

Objectives Premature birth is associated with a wide range of complications in later life, including structural and functional neurological abnormalities and altered pain sensitivity. We investigated whether during anaesthesia premature-born children display different patterns of background EEG activity and exhibit increased responses to nociceptive stimuli. Methods We examined background EEG and time-locked responses to clinical cannulation in 45 children (mean age (±SD) at study: 4.9 (± 3.0) years) under sevoflurane monoanaesthesia maintained at a steady-state end-tidal concentration of 2.5%. 15 were born prematurely (mean gestational age at birth: 29.2 ± 3.9 weeks) and 30 were age-matched term-born children. Results Background levels of alpha and beta power were significantly lower in the premature-born children compared to term-born controls (p = 0.048). Clinical cannulation evoked a significant increase in delta activity (p = 0.032), which was not significantly different between the two groups (p = 0.44). Conclusions The results indicate that whilst under anaesthesia premature-born children display different patterns of background brain activity compared to term-born children. Significance As electrophysiological techniques are increasingly used by anaesthetists to gauge anaesthetic depth, differences in background levels of electrophysiological brain activity between premature and term-born children may be relevant when considering titration of anaesthetic dose.

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

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

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

Preterm birth results in alterations in neural connectivity, but the impact of prematurity on the functional organization of the developing brain has yet to be explored. To test the hypothesis that preterm birth alters cortical organization during the late second and third trimesters of gestation, we interrogated cerebral lateralization at rest in 26 very preterm subjects (birth weight 500–1500 g) with no evidence of brain injury and 25 healthy term control subjects at term equivalent age. Employing an unbiased voxel-based measure of functional connectivity, these data demonstrated that cerebral lateralization is impaired in the prematurely-born. At term equivalent age, preterm neonates showed significantly less lateralization in regions subserving both receptive and expressive language, left Brodmann (BA) areas insula-BA22-BA21 and L BA45-BA47 (p<0.05 corrected for multiple comparisons for both). Exploratory region of interest analyses demonstrated significantly less inter-hemispheric connectivity from L BA22 to R BA22 in preterm infants compared to term controls (p<0.005) and from R BA22 to its homolog (p<0.005). L BA22, Wernicke’s area, was more strongly connected to R BA39, foreshadowing neural networks for language in preterm subjects at school age, adolescence and young adulthood. For these very preterm neonates born at less than 30 weeks PMA, the degree of prematurity had no influence on lateralization in these differential regions. PMID:25528658

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

Purpose We compared postural stability and subjective visual vertical performance in a group of very preterm-born children aged 3-4 years and in a group of age-matched full-term children. Materials and Methods A platform (from TechnoConcept) was used to measure postural control in children. Perception of subjective visual vertical was also recorded with posture while the child had to adjust the vertical in the dark or with visual perturbation. Two other conditions (control conditions) were also recorded while the child was on the platform: for a fixation of the vertical bar, and in eyes closed condition. Results Postural performance was poor in preterm-born children compared to that of age-matched full-term children: the surface area, the length in medio-lateral direction and the mean speed of the center of pressure (CoP) were significantly larger in the preterm-born children group (p < 0.04, p < 0.01, and p < 0.04, respectively). Dual task in both groups of children significantly affected postural control. The subjective visual vertical (SVV) values were more variable and less precise in preterm-born children. Discussion-Conclusions We suggest that poor postural control as well as perception of verticality observed in preterm-born children could be due to immaturity of the cortical processes involved in the motor control and in the treatment of perception and orientation of verticality.

The objective of this article is to evaluate whether sleep patterns and quality differed between adolescents born preterm and term, and to further explore whether differences in sleep patterns were explained by differences in mediating factors such as mood, behavior, or socioeconomic status. Five hundred and one 16- to 19-year-old children in the longitudinal Cleveland Children's Sleep and Health Study cohort underwent overnight polysomnography (PSG), wore wrist actigraphs, and completed sleep logs for 1 week. The modified Epworth Sleepiness Scale, the Adolescent Sleep Hygiene Scale, and the Adolescent Sleep-Wake Scale were used to further assess sleep. Adolescents born preterm demonstrated significantly (p < .05) earlier bed and wake times and sleep midpoints (approximately 22 min after adjusting for demographic and psychosocial factors) by actigraphy. They also had significantly fewer arousals (by PSG), and reported being more rested and alert in the morning, as well as less sleepiness and fatigue. These findings support a growing body of evidence that perinatal factors may influence sleep phenotypes later in life. These factors may reflect developmental influences, as well as the influence of parenting styles on children's sleep. PMID:24283662

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

Being born prematurely associates with greater cardiovascular disease (CVD) risk in adulthood. Less understood are the unique and joint associations of dietary patterns and behaviors to this elevated risk among adults who are born prematurely. We aimed to model the associations between term status, dietary and lifestyle behaviors with CVD risk factors while accounting for the longitudinal effects of family protection, and medical or environmental risks. In wave-VIII of a longitudinal study, 23-year olds born prematurely (PT-adults, n = 129) and full term (FT-adults, n = 38) survey-reported liking for foods/beverages and activities, constructed into indexes of dietary quality and sensation-seeking, dietary restraint and physical activity. Measured CVD risk factors included fasting serum lipids and glucose, blood pressure and adiposity. In bivariate relationships, PT-adults reported lower dietary quality (including less affinity for protein-rich foods and higher affinity for sweets), less liking for sensation-seeking foods/activities, and less restrained eating than did FT-adults. In comparison to nationally-representative values and the FT-adults, PT-adults showed greater level of CVD risk factors for blood pressure and serum lipids. In structural equation modeling, dietary quality completely mediated the association between term status and HDL-cholesterol (higher quality, lower HDL-cholesterol) yet joined term status to explain variability in systolic blood pressure (PT-adults with lowest dietary quality had highest blood pressures). Through lower dietary quality, being born prematurely was indirectly linked to higher cholesterol/HDL, higher LDL/HDL and elevated waist/hip ratios. The relationship between dietary quality and CVD risk was strongest for PT-adults who had developed greater cumulative medical risk. Protective environments failed to attenuate relationships between dietary quality and elevated CVD risk among PT-adults. In summary, less healthy dietary

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

First- and second-born adolescents' and their parents' perceptions of adolescents' decision-making autonomy were compared from ages 12 to 19 in a longitudinal sample of 145 predominantly White, middle class families. Utilizing a multivariate, multilevel modeling approach, differences in perceptions of adolescents' autonomy between parents and each adolescent, as well as by social-cognitive domain were examined. The present study found that when comparing parents' perceptions of their children at the same age, second-borns were granted more autonomy regarding conventional issues than first-borns during early adolescence, but by later adolescence first-borns were granted more autonomy regarding prudential issues than second-borns. However, comparisons between adolescents' and siblings' perceptions showed no differences. Potential reasons for, and implications of, differences in perceptions of adolescent autonomy are discussed.

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

Although studies of long-term outcomes of children born preterm consistently show low intelligence quotient (IQ) and visual-motor impairment, studies of their performance in language and reading have found inconsistent results. In this study, we examined which specific language and reading skills were associated with prematurity independent of the effects of gender, socioeconomic status (SES), and IQ. Participants from two study sites (N=100) included 9-16-year old children born before 36 weeks gestation and weighing less than 2500 grams (preterm group, n=65) compared to children born at 37 weeks gestation or more (full-term group, n=35). Children born preterm had significantly lower scores than full-term controls on Performance IQ, Verbal IQ, receptive and expressive language skills, syntactic comprehension, linguistic processing speed, verbal memory, decoding, and reading comprehension but not on receptive vocabulary. Using MANCOVA, we found that SES, IQ, and prematurity all contributed to the variance in scores on a set of six non-overlapping measures of language and reading. Simple regression analyses found that after controlling for SES and Performance IQ, the degree of prematurity as measured by gestational age group was a significant predictor of linguistic processing speed, β=-.27, p<.05, R(2)=.07, verbal memory, β=.31, p<.05, R(2)=.09, and reading comprehension, β=.28, p<.05, R(2)=.08, but not of receptive vocabulary, syntactic comprehension, or decoding. The language and reading domains where prematurity had a direct effect can be classified as fluid as opposed to crystallized functions and should be monitored in school-aged children and adolescents born preterm.

Three young women who developed premature ovarian insufficiency following quadrivalent human papillomavirus (HPV) vaccination presented to a general practitioner in rural New South Wales, Australia. The unrelated girls were aged 16, 16, and 18 years at diagnosis. Each had received HPV vaccinations prior to the onset of ovarian decline. Vaccinations had been administered in different regions of the state of New South Wales and the 3 girls lived in different towns in that state. Each had been prescribed the oral contraceptive pill to treat menstrual cycle abnormalities prior to investigation and diagnosis. Vaccine research does not present an ovary histology report of tested rats but does present a testicular histology report. Enduring ovarian capacity and duration of function following vaccination is unresearched in preclinical studies, clinical and postlicensure studies. Postmarketing surveillance does not accurately represent diagnoses in adverse event notifications and can neither represent unnotified cases nor compare incident statistics with vaccine course administration rates. The potential significance of a case series of adolescents with idiopathic premature ovarian insufficiency following HPV vaccination presenting to a general practice warrants further research. Preservation of reproductive health is a primary concern in the recipient target group. Since this group includes all prepubertal and pubertal young women, demonstration of ongoing, uncompromised safety for the ovary is urgently required. This matter needs to be resolved for the purposes of population health and public vaccine confidence. PMID:26425627

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

The current study examined whether changes in maternal behaviors following an evidence-based treatment—Parent Child Interaction Therapy (PCIT)—was associated with improvements in cardiac vagal regulation in young children born premature. Participants included 28 young children (mean age = 37.79 months) that were born premature and presented with elevated externalizing behavior problems. To assess cardiac vagal regulation, resting measures of respiratory sinus arrhythmia (RSA) and RSA change (withdrawal or suppression) to a clean-up task were derived pre and post-treatment. Results indicated that an increase in behaviors mothers are taught to use during treatment (i.e., do skills—praise, reflection, and behavioral descriptions) were associated with an improvement in children’s post-treatment RSA suppression levels. The current study illustrates the important role of caregiver behavior in promoting physiological regulation in children born premature. PMID:22721742

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

AIM—To examine the spectrum of neurological dysfunction and perceptual-motor difficulties at school age in a cohort of prematurely born children, and the relation of these measures to neonatal brain lesions, intelligence quotient, and behavioural adjustment. METHOD—One hundred and eighty three children were tested at the age of 6 years using Touwen's Examination of the Child with Minor Neurological Dysfunction, the Movement Assessment Battery for Children (Movement ABC), the Developmental Test of Visual-Motor Integration (VMI), British Ability Scales, and Rutter Scales. RESULTS—Twenty six children had definite cerebral palsy and one was blind. Of the remaining 156, the proportions falling below the 15th centile point were 31% on Touwen's Examination, 44% on the Movement ABC, and 17% on the VMI. Forty two passed all three tests. No child with a normal ultrasound scan developed cerebral palsy, whereas nearly all those with major lesions did. Minor lesions, however, were not generally predictive of later outcome. Correlations between the tests were generally low. CONCLUSIONS—These findings stress the need to assess neurological and perceptual motor functioning separately at school age and to monitor relationships with other aspects of development. Keywords: neurological signs; perceptual-motor difficulties; prematurity; follow up. PMID:9059179

BACKGROUND AND OBJECTIVES: Extremely preterm infants and infants born to adolescent mothers are at risk for adverse developmental. The objectives were to evaluate development and behavior outcomes of extremely low birth weight (ELBW) infants born to adolescent mothers <20 compared with adult mothers ≥20 years and to identify socioeconomic risk factors that affect outcomes. METHODS: Retrospective cohort analysis of 211 infants >27 weeks of adolescent mothers and 1723 infants of adult mothers at Neonatal Research Network centers from 2008 to 2011. Groups were compared and regression models were run to predict 18- to 22-month adverse outcomes. Primary outcomes were Bayley-III scores, neurodevelopmental impairment, and Brief Infant Toddler Social Emotional Assessment problem scores (BITSEA/P) ≥75th percentile. RESULTS: Adolescent mothers were more often single, Hispanic, less educated, and had public insurance. By 18 to 22 months, their children had significantly increased rates of having lived ≥3 places (21% vs 9%), state supervision (7% vs 3%), rehospitalization (56% vs 46%), and BITSEA/P ≥75th percentile (50% vs 32%) and nonsignificant Bayley-III language scores <85 (56% vs 49%, P = .07). In regression analysis, children of adolescent mothers were more likely to have BITSEA/P ≥75th percentile (relative risk 1.50, 95% confidence interval 1.08–2.07). Living ≥3 places and nonwhite race were predictors of adverse behavior. State supervision was an independent predictor of each Bayley-III composite <70 and neurodevelopmental impairment. CONCLUSIONS: ELBW infants of adolescent mothers experience high social and environmental risks that are associated with adverse behavior outcomes. These findings inform the need for comprehensive follow-up, coordinated care services, and behavior interventions for ELBW infants of adolescent mothers. PMID:25963007

Premature autonomy describes a developmental dynamic where parents of high-risk adolescents reduce their involvement and guidance when confronted with challenges of problem behaviour and the influence of deviant friendships. This dynamic was tested on the sample of Oregon Youth Study boys (N=206), whose family management practices and friendships were observed on videotaped interaction tasks. Latent growth curve models were used to examine longitudinal trends between deviant friendship interactions and family management. Direct observations of deviant friendship process at age 14 were associated with degradation in family management during adolescence. A comparison of antisocial and well-adjusted boys clarified that parents of antisocial boys (started early and persisted) decreased family management around puberty, in comparison to parents of well-adjusted boys who maintained high levels of family management through adolescence. In predicting late adolescent problem behaviour, there was a statistically reliable interaction between family management degradation and deviant peer involvement in adolescence in support of the premature autonomy hypothesis. Adolescent males involved in deviant friendships, and whose parents decreased their family management, were most likely to use marijuana and commit antisocial acts at age 18. The implications for interventions that target adolescents are discussed. PMID:15475044

Aim The aim of this study was to investigate long-term cognitive outcome in a cohort of 18-year-olds born preterm and previously assessed at the age of 5.5. Methods We tested 134 adolescents born preterm with a very low birthweight of <1500 g and 94 term-born controls with a comprehensive cognitive battery at 18 years of age. The cohort was subdivided into 73 extremely preterm, 42 very preterm and 19 moderately preterm infants with gestational ages of 23–27, 28–31 and 32–36 weeks, respectively. The moderately preterm group was dominated by adolescents born small for gestational age. Results Very preterm adolescents performed on a par with term-born controls. In contrast, extremely preterm adolescents displayed inferior results on all cognitive tests, more so if they had suffered neonatal complications. Moderately preterm adolescents scored lower than very preterm and full-term born adolescents, particularly on complex cognitive tasks. Conclusion Adolescents born at 28 weeks of gestation or later, with appropriate birthweight and no perinatal complications, functioned like term-born peers at 18 years of age. Extremely preterm birth per se posed a risk for long-term cognitive deficits, particularly executive deficits. Adolescents born moderately preterm but small for gestational age were at risk of general cognitive deficits. PMID:25394225

Although language difficulties are common in children born prematurely, robust neuroanatomical correlates of these impairments remain to be established. This study investigated whether the greater prevalence of language problems in preterm (versus term-born) children might reflect injury to major intra- or interhemispheric white matter pathways…

Very low birth weight (VLBW) premature born infants have a high risk to develop visual perceptual and learning deficits as well as widespread functional and structural brain abnormalities during infancy and childhood. Whether and how prematurity alters neural specialization within visual neural networks is still unknown. We used functional and structural brain imaging to examine the visual semantic system of VLBW born (<1250 g, gestational age 25-32 weeks) adolescents (13-15 years, n = 11, 3 males) and matched term born control participants (13-15 years, n = 11, 3 males). Neurocognitive assessment revealed no group differences except for lower scores on an adaptive visuomotor integration test. All adolescents were scanned while viewing pictures of animals and tools and scrambled versions of these pictures. Both groups demonstrated animal and tool category related neural networks. Term born adolescents showed tool category related neural activity, i.e. tool pictures elicited more activity than animal pictures, in temporal and parietal brain areas. Animal category related activity was found in the occipital, temporal and frontal cortex. VLBW born adolescents showed reduced tool category related activity in the dorsal visual stream compared with controls, specifically the left anterior intraparietal sulcus, and enhanced animal category related activity in the left middle occipital gyrus and right lingual gyrus. Lower birth weight of VLBW adolescents correlated with larger thickness of the pericalcarine gyrus in the occipital cortex and smaller surface area of the superior temporal gyrus in the lateral temporal cortex. Moreover, larger thickness of the pericalcarine gyrus and smaller surface area of the superior temporal gyrus correlated with reduced tool category related activity in the parietal cortex. Together, our data suggest that very low birth weight predicts alterations of higher order visual semantic networks, particularly in the dorsal stream. The differences

Adolescent pregnancy remains a persistent societal problem. Both teenage mothers and the fathers of their babies are unprepared for parenthood and often drop out of school, take low-paying jobs, and never complete their education. Fathers of babies born to adolescent mothers are a critical but often forgotten component of the adolescent pregnancy…

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

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

Preterm-born children commonly experience motor, cognitive, and learning difficulties that may be accompanied by altered brain microstructure, connectivity, and neurochemistry. However, the mechanisms linking the altered neurophysiology with the behavioral outcomes are unknown. Here we provide the first physiological evidence that human adolescents born preterm at or before 37 weeks of completed gestation have a significantly reduced capacity for cortical neuroplasticity, the key overall mechanism underlying learning and memory. We examined motor cortex neuroplasticity in three groups of adolescents who were born after gestations of ≤32 completed weeks (early preterm), 33-37 weeks (late preterm), and 38-41 weeks (term) using a noninvasive transcranial magnetic brain stimulation technique to induce long-term depression (LTD)-like neuroplasticity. Compared with term-born adolescents, both early and late preterm adolescents had reduced LTD-like neuroplasticity in response to brain stimulation that was also associated with low salivary cortisol levels. We also compared neuroplasticity in term-born adolescents with that in term-born young adults, finding that the motor cortex retains a relatively enhanced neuroplastic capacity in adolescence. These findings provide a possible mechanistic link between the altered brain physiology of preterm birth and the subsequent associated behavioral deficits, particularly in learning and memory. They also suggest that altered hypothalamic-pituitary-adrenal axis function due to preterm birth may be a significant modulator of this altered neuroplasticity. This latter finding may offer options in the development of possible therapeutic interventions. PMID:23152623

While the risk for symptomatic atherosclerotic disease increases after menopause, currently recognized risk factors do not identify ongoing disease processes in low-risk women. This study tested the hypothesis that circulating cell-derived microparticles may reflect disease processes in women defined as low risk by the Framingham risk score. The concentration and phenotype of circulating microparticles were evaluated in a cross-sectional study of apparently healthy menopausal women, screened for enrollment into the Kronos Early Estrogen Prevention Study. Microparticles were evaluated by flow cytometry, and coronary artery calcification (CAC) was scored using 64-slice computed tomography scanners. The procoagulant activity of isolated microparticles was determined with a sensitive fluorescent thrombin generation assay. Chronological age, body mass index, serum lipids, systolic blood pressure (Framingham risk score < 10%, range 1–3%), and high-sensitivity C-reactive protein did not differ significantly among women with low (0 < 35; range, 0.3–32 Agatston units) or high (>50; range, 93–315 Agatston units) CAC compared with women without calcification. The total concentration and percentage of microparticles derived from platelets and endothelial cells were greatest in women with high CAC scores. The thrombin-generating capacity of the isolated microparticles correlated with phosphatidylserine expression, which also was greatest in women with high CAC scores. The percentages of microparticles expressing granulocyte and monocyte markers were not significantly different among groups. Therefore, the characterization of platelet and endothelial microparticles may identify early menopausal women with premature CAC who would not otherwise be identified by the usual risk factor analysis.

Background Preterm children are at risk for executive function (EF) problems, which have been linked to behavior and learning problems in full term children. In this study, we examine the relationship between EF and functional outcomes in preterm children. Aims To evaluate (1) EF skills of 9- to 16-year-old children born across the spectrum of gestational age (GA), (2) relationship of degree of prematurity to EF skills, and (3) contributions of EF skills to two functional outcomes--reading scores and parent-rated child function. Method Preterm children <36 weeks gestation (n=72) were compared to full term children (n=42) of similar age, gender and SES, on measures of EF, reading, and parent-ratings of child function. Multiple regression models evaluated contributions to EF skills and functional outcomes. Results Compared to full term controls, preterm children had poorer EF performance on a complex planning and organization task and did not increase planning time as task difficulty increased. Their spatial memory capacity was not different. GA contributed to EF skills, but was mediated by IQ. EF contributed to the variance in reading skills but did not add to the variance in reading when IQ was considered. EF skills significantly contributed to the variance in parent-rated child function, but IQ did not. Conclusion EF skills contribute to measures of functional outcome in this high-risk population. The use of EF skills as an early marker for learning and functional problems and as a target for intervention in children born preterm warrants future study. PMID:21849240

Objective To study the relationship between neighborhood demographic characteristics (disadvantage, racial concentration) and the birthweight of infants born to adolescent mothers, potentially as mediated by smoking, prenatal care use, or perceptions of neighborhood safety. Methods Data from Waves I and IV of the National Longitudinal Survey of Adolescent Health were analyzed. Birthweight (continuous) and low birthweight (<2.5 kg) of singleton infants born to non-Hispanic Black and non-Hispanic White adolescent mothers (<20 years) after Wave I were examined as outcomes. Neighborhood demographic characteristics included Census Block Group socioeconomic disadvantage and Black racial concentration. Possible mediators (smoking during pregnancy, early initiation of prenatal care, and perceptions of safety) were also examined. Controls for adolescent baseline age, age at pregnancy, body mass index (BMI) and parental education were included. Analyses were run stratified on race. Results Baseline continuous birthweight, BMI and neighborhood demographics varied significantly between non-Hispanic Black and White adolescent mothers, with Black adolescent mothers evidencing lower birthweight and higher BMI, neighborhood disadvantage and Black racial concentration. In multivariable analyses among Black adolescent mothers, Black racial concentration was positively associated with birthweight, and negatively associated with low birthweight; no mediators were supported. Neighborhood disadvantage and Black racial concentration were unassociated with birthweight outcomes among White adolescent mothers. Conclusions Infants born to Black adolescent mothers evidenced higher birthweight with increasing Black neighborhood concentration. Further exploration of mechanisms by which Black racial concentration may positively impact birthweight is warranted. PMID:23771237
The issues of sexuality and premature parenthood with the background of the Black experience in the United States are discussed. According to a 1986 study, 40% of US girls get pregnant at least once before the age of 20. In 1981, 45% of teenage pregnancies were terminated, and in 1982, 46% of girls 14-19 years old had had sexual intercourse. The gap between Black and White adolescent women regarding sexual intercourse has essentially disappeared, indicating that the underlying causes of teenage pregnancy are social not racial. The costs of adolescent childbearing are huge: in 1985 the public cost was at least 16.65 million dollars. In response to this crisis, many states have been searching for effective solutions enlisting clinics, schools, and social service agencies. The Black church has been a central institution within the Black community, in the forefront of many social changes with the ability to mobilize congregations and the community. Therefore, the cooperation of social service agencies, community groups, and the religious community could be fruitful in preventing adolescent pregnancies and childbearing. Such a venture would first require understanding the processes of adolescent development, self-esteem, socialization, relationship building, gender differences in physical and psychological changes, and moral development. A 1986 Gallup poll showed that 74% of 13-15 year old youth said that religion was one of the most important influences in their lives, indicating that they would be perceptive to moral reasoning. However, the fear of genocide was significant among the Black population (39%) when birth control and family planning programs were mentioned. This had to do with their brutal treatment in the past and coercive sterilization proposals to reduce welfare rolls. To overcome such fears and still prevent adolescent pregnancy, the Black church should organize workshops for parents and adolescents about sexual development, birth control, and the

Background Adolescents born extremely preterm (EP; <28 weeks' gestation) and/or extremely low birthweight (ELBW; <1000 g) experience high rates of visual impairments, however the potential neural correlates of visual impairments in EP/ELBW adolescents require further investigation. This study aimed to: 1) compare optic radiation and primary visual cortical structure between EP/ELBW adolescents and normal birthweight controls; 2) investigate associations between perinatal factors and optic radiation and primary visual cortical structure in EP/ELBW adolescents; 3) investigate associations between optic radiation and primary visual cortical structure in EP/ELBW adolescents and the odds of impaired vision. Methods 196 EP/ELBW adolescents and 143 controls underwent magnetic resonance imaging at a mean age of 18 years. Optic radiations were delineated using constrained spherical deconvolution based probabilistic tractography. Primary visual cortices were segmented using FreeSurfer software. Diffusion tensor variables and tract volume of the optic radiations, as well as volume, surface area and thickness of the primary visual cortices, were estimated. Results Axial, radial and mean diffusivities within the optic radiations, and primary visual cortical thickness, were higher in the EP/ELBW adolescents than controls. Within EP/ELBW adolescents, postnatal corticosteroid exposure was associated with altered optic radiation diffusion values and lower tract volume, while decreasing gestational age at birth was associated with increased primary visual cortical volume, area and thickness. Furthermore, decreasing optic radiation fractional anisotropy and tract volume, and increasing optic radiation diffusivity in EP/ELBW adolescents were associated with increased odds of impaired vision, whereas primary visual cortical measures were not associated with the odds of impaired vision. Conclusions Optic radiation and primary visual cortical structure are altered in EP/ELBW adolescents

Background: Adolescent pregnancy and childbirth are associated with increased risk and challenges for both mothers and birth outcomes. Objective: To investigate the associations of growth change over time with parenting factors and to compare the differences between children born to adolescent and adult mothers in Taiwan. Materials and Methods: The dataset retrieved from Taiwan birth cohort study (TBCS) was collected by interviews using structured questionnaires, birth certificate and Passport of Well-baby Care of each child. Changes in body weight, body height and head circumference from birth to 18 months, as well as other variables were assessed by statistical analysis. Results: There were 4.13% births born to adolescent mothers in 2005. Higher ratios of breastfeeding and working were found among adult mothers (p<0.001). Significantly higher percentage of adolescent mothers caregave their infants up to 18 months (p<0.001). Children born to adolescent mothers were associated with statistically significant lower body weight (p<0.001), body height (p<0.001) and head circumference (p<0.001) in spite of velocity and slop of growth patterns were similar over time. Breastfeeding did not significantly affected growth rate during the first 6 months. Generalized estimated equation models showed that gender and preterm birth were predictive factors for birth outcomes (both p<0.001) and correlated to changes over time. Conclusion: Adolescent childbearing was associated with preterm birth and lower body weight, body height and head circumference from birth to 18 months. The changes in growth and development among children born to adolescent mothers remain to be followed and evaluated with the TBCS. PMID:25709629

While cross-sectional neuroimaging studies on cortical development predict reductions in cortical volume (surface area and thickness) during adolescence, this is the first study to undertake a longitudinal assessment of cortical surface area changes across the continuous cortical surface during this period. We studied the developmental dynamics of cortical surface area and thickness in adolescents and young adults (aged 15-20) born with very low birth weight (VLBW; <1500 g) as well as in term-born controls. Previous studies have demonstrated brain structural abnormalities in cortical morphology, as well as long-term motor, cognitive and behavioral impairments, in adolescents and young adults with VLBW, but the developmental dynamics throughout adolescence have not been fully explored. T1-weighted MRI scans from 51 VLBW (27 scanned twice) and 79 term-born adolescents (37 scanned twice) were used to reconstruct the cortical surface and produce longitudinal estimates of cortical surface area and cortical thickness. Linear mixed model analyses were performed, and the main effects of time and group, as well as time × group interaction effects, were investigated. In both groups, cortical surface area decreased up to 5% in some regions, and cortical thickness up to 8%, over the five-year period. The most affected regions were located on the lateral aspect of the hemispheres, in posterior temporal, parietal and to some extent frontal regions. There was no significant interaction between time and group for either morphometry variable. In conclusion, cortical thickness decreases from 15 to 20 years of age, in a similar fashion in the clinical and control groups. Moreover, we show for the first time that developmental trajectories of cortical surface area in preterm and term-born adolescents do not diverge during adolescence. PMID:26773236

Evidence-based psychosocial interventions for externalizing behavior problems in children born premature have not been reported in the literature. This single-case study describes Parent-Child Interaction Therapy (PCIT) with a 23-month-old child born at 29 weeks gestation weighing 1,020 grams, who presented with significant externalizing behavior problems. Treatment outcome was assessed using standard measures of maternal and child functioning and observational measures of the parent-child interaction, as well as a physiological measure of heart rate variability (i.e., vagal tone) used to assess parasympathetic control in the child. Maternal reports of child behavior problems and their own stress and depressive symptoms decreased after treatment. Behavioral observations demonstrated improved parenting practices and child compliance, and vagal tone showed comparable increases as well. Results suggest that PCIT is a promising psychosocial intervention for children born premature with externalizing behavior problems, and that vagal tone may be a useful measure of treatment outcome.

Functional magnetic resonance imaging (fMRI) was used to map hippocampal activation during a declarative memory task in a sample of 14 adolescents with antecedents of prematurity (AP). The sample with AP was matched by age, sex and handedness with 14 full-term controls with no history of neurological or psychiatric illness. The target task consisted in learning 16 novel face-name pairs, and the control task involved the examination of two repeated face-name pairs. Stereological methods were also used to quantify hippocampal volumes. In both groups, we observed increased activation in the learning condition compared to the control task in the right fusiform gyrus and the left inferior occipital gyrus, but only premature subjects activated the hippocampus. Group comparison of the activation versus control conditions showed that prematures had greater activity in the right hippocampus than controls during the encoding of the word-face association. Volumetric analyses showed a significant left hippocampal volume loss in adolescents with AP. In addition, we found a significant positive correlation in the premature group between right hippocampal activation and face-name recognition. Functional MRI data also correlated with structural MRI data: right hippocampal activation correlated positively with right hippocampal volume. Our findings are consistent with previous studies of brain plasticity after focal lesions. Left hippocampal tissue loss may be related to an increase in contralateral brain activity, probably reflecting a compensatory mechanism. Our data also suggest that this plasticity is not enough to achieve normal performance. PMID:15784435

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

Objectives. We assessed risk of cigarette smoking initiation among Hispanics/Latinos during adolescence by migration status and gender. Methods. The Hispanic Community Health Study/Study of Latinos (HCHS/SOL) surveyed persons aged 18 to 74 years in 2008 to 2011. Our cohort analysis (n = 2801 US-born, 13 200 non–US-born) reconstructed participants’ adolescence from 10 to 18 years of age. We assessed the association between migration status and length of US residence and risk of cigarette smoking initiation during adolescence, along with effects of gender and Hispanic/Latino background. Results. Among individuals who migrated by 18 years of age, median age and year of arrival were 13 years and 1980, respectively. Among women, but not men, risk of smoking initiation during adolescence was higher among the US-born (hazard ratio [HR] = 2.10; 95% confidence interval [CI] = 1.73, 2.57; P < .001), and those who had resided in the United States for 2 or more years (HR = 1.47; 95% CI = 1.11, 1.96; P = .01) than among persons who lived outside the United States. Conclusions. Research examining why some adolescents begin smoking after moving to the United States could inform targeted interventions. PMID:25322293

Diffusion properties of white matter tracts have been associated with individual differences in reading. Individuals born preterm are at risk of injury to white matter. In this study we compared the associations between diffusion properties of white matter and reading skills in children and adolescents born full term and preterm. 45 participants, aged 9-17 years, included 26 preterms (born < 36 weeks' gestation) and 19 full-terms. Tract fractional anisotropy (FA) profiles were generated for five bilateral white matter tracts previously associated with reading: anterior superior longitudinal fasciculus (aSLF), arcuate fasciculus (Arc), corticospinal tract (CST), uncinate fasciculus (UF) and inferior longitudinal fasciculus (ILF). Mean scores on reading for the two groups were in the normal range and were not statistically different. In both groups, FA was associated with measures of single word reading and comprehension in the aSLF, AF, CST, and UF. However, correlations were negative in the full term group and positive in the preterm group. These results demonstrate variations in the neurobiology of reading in children born full term and preterm despite comparable reading skills. Findings suggest that efficient information exchange required for strong reading abilities may be accomplished via a different balance of neurobiological mechanisms in different groups of readers.

Diffusion properties of white matter tracts have been associated with individual differences in reading. Individuals born preterm are at risk of injury to white matter. In this study we compared the associations between diffusion properties of white matter and reading skills in children and adolescents born full term and preterm. 45 participants, aged 9–17 years, included 26 preterms (born < 36 weeks' gestation) and 19 full-terms. Tract fractional anisotropy (FA) profiles were generated for five bilateral white matter tracts previously associated with reading: anterior superior longitudinal fasciculus (aSLF), arcuate fasciculus (Arc), corticospinal tract (CST), uncinate fasciculus (UF) and inferior longitudinal fasciculus (ILF). Mean scores on reading for the two groups were in the normal range and were not statistically different. In both groups, FA was associated with measures of single word reading and comprehension in the aSLF, AF, CST, and UF. However, correlations were negative in the full term group and positive in the preterm group. These results demonstrate variations in the neurobiology of reading in children born full term and preterm despite comparable reading skills. Findings suggest that efficient information exchange required for strong reading abilities may be accomplished via a different balance of neurobiological mechanisms in different groups of readers.

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

Background The hippocampus has been reported to be structurally and functionally altered as a sequel of very preterm birth (<33 weeks gestation), possibly due its vulnerability to hypoxic–ischemic damage in the neonatal period. We examined hippocampal volumes and subregional morphology in very preterm born individuals in mid- and late adolescence and their association with psychiatric outcome. Methods Structural brain magnetic resonance images were acquired at two time points (baseline and follow-up) from 65 ex-preterm adolescents (mean age = 15.5 and 19.6 years) and 36 term-born controls (mean age=15.0 and 19.0 years). Hippocampal volumes and subregional morphometric differences were measured from manual tracings and with three-dimensional shape analysis. Psychiatric outcome was assessed with the Rutter Parents’ Scale at baseline, the General Health Questionnaire at follow-up and the Peters Delusional Inventory at both time points. Results In contrast to previous studies we did not find significant difference in the cross-sectional or longitudinal hippocampal volumes between individuals born preterm and controls, despite preterm individual having significantly smaller whole brain volumes. Shape analysis at baseline revealed subregional deformations in 28% of total bilateral hippocampal surface, reflecting atrophy, in ex-preterm individuals compared to controls, and in 22% at follow-up. In ex-preterm individuals, longitudinal changes in hippocampal shape accounted for 11% of the total surface, while in controls they reached 20%. In the whole sample (both groups) larger right hippocampal volume and bilateral anterior surface deformations at baseline were associated with delusional ideation scores at follow-up. Conclusions This study suggests a dynamic association between cross-sectional hippocampal volumes, longitudinal changes and surface deformations and psychosis proneness. PMID:26091104

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

This case series assesses white matter microstructure of the cerebellar peduncles in 4 adolescents born preterm with enlarged ventricles and reduced white matter volume in the cerebrum but no apparent injury to the cerebellum. Subjects (ages 12-17 years, gestational age 26-32 weeks, birth weight 825-2211 g) were compared to a normative sample of 19 full-term controls (9-17 years, mean gestational age 39 weeks, mean birth weight 3154 g). Tract profiles for each of the cerebellar peduncles were generated by calculating fractional anisotropy at 30 points along the central portion of each tract. One or more case subjects exhibited higher fractional anisotropy beyond the 90th percentile in the inferior, middle, and superior cerebellar peduncles. Findings demonstrate that differences in cerebellar white matter microstructure can be detected in the absence of macrostructural cerebellar abnormalities. PMID:26116381

The aim of this article is to investigate the long-term developmental consequences of being born to a substance-using mother, focusing on cognitive functions, attention, emotional and social development. The longitudinal sample comprised 48 adolescents aged 12-16 at the time of follow-up assessments, which included the Wechsler Intelligence Scale for Children-III, the Test of Everyday Attention for Children, The Tower of London test and the Strengths and Difficulties Questionnaire. The adolescents scored significantly lower than the norms on Wechsler's subtests and Full-Scale IQ, and on The Everyday Attention test. There were few differences on the Strengths and Difficulties Questionnaire. The girls reported significantly more hyperactivity than the British norms, and the teachers reported higher impact scores in boys, compared to the British norms. Thus, the results on cognitive consequences of maternal substance use appear to be very substantial while the emotional and social consequences do not. The results suggest serious negative effects of substance exposure in utero on attention and cognitive functioning in general. PMID:24828950

The worldwide rate of premature birth is increasing. Survival has also improved, even for very preterm infants, meaning greater numbers of preterm infants surviving into later life. This has led to greater attention being focused on long-term outcomes. Recent interest in the Developmental Origins of Health and Disease has highlighted the importance of early life growth and nutritional exposures for chronic diseases such as cardiovascular disease, osteoporosis and type 2 diabetes. There is evidence linking preterm birth and poor growth in utero with worse long-term cognitive outcome, but also evidence to link more rapid growth in certain epochs of early life with adverse metabolic outcomes. The current data suggest that a diverse range of metabolic outcomes are affected by preterm birth, and that adult survivors may be more likely to develop certain chronic diseases. There are data to show that catch-up growth during the neonatal period and in infancy may affect these later outcomes, but studies are inconsistent in their findings. In addition, it is clear that lifestyle factors during childhood and adolescence have a major impact on metabolic disease that may be greater in magnitude to the effects of early growth and nutritional exposures.

In 1983, data of a unique nationwide cohort of 1338 very preterm (<32 weeks of gestation) or VLBW (birth weight<1500g) infants in the Netherlands was collected and followed at several ages until they reached the age of 19 years. At 19 years of age a more extensive follow-up study was done, including questionnaires, tests on a computer and a full physical exam. These studies provide insight into how Dutch adolescents at 19 years of age, who were born very preterm or with a very low birth weight (VLBW), reach adulthood. At 19 years, 705 POPS participants participated (74% of 959 still alive). Outcome measures at 19 years included: physical outcomes (e.g. blood pressure), cognition, behavior, quality of life, and impact of handicaps. The POPS participants showed more impairments on most outcome measures at various ages, compared to norm data. Major handicaps remained stable as the children grew older, but minor handicaps and disabilities increased. At 19 years of age, only half (47.1%) of the survivors had no disabilities and no minor or major handicaps. Especially those born small for gestational age (SGA) seem most vulnerable. These long-term results help to support preterm and SGA born children and adolescents in reaching independent adulthood, and stress the need for long term follow-up studies and to promote prevention of disabilities and of preterm birth itself.

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

Objectives To compare brain volumes in adolescents who were born extremely preterm (<28 weeks gestation) who had received postnatal dexamethasone, and to determine if there was a postnatal dexamethasone dose–response effect on brain volumes. Study design Geographical cohort study of extremely preterm adolescents born in 1991-1992 in Victoria, Australia. T1-weighted magnetic resonance imaging was performed at 18 years of age. Segmented and parcellated brain volumes were calculated using an automated segmentation method (FreeSurfer) and compared between groups, with and without adjustment for potential confounders. The relationships between total postnatal dexamethasone dose and brain volumes were explored using linear regression. Results Of the 148 extremely preterm participants, 55 (37%) had received postnatal dexamethasone, with a cumulative mean dose of 7.7 mg/kg. Compared with participants who did not receive postnatal dexamethasone, those who did had smaller total brain tissue volumes (mean difference −3.6%, 95% CI [−7.0%, −0.3%], P value = .04) and smaller white matter, thalami, and basal ganglia volumes (all P < .05). There was a trend of smaller total brain and white matter volumes with increasing dose of postnatal dexamethasone (regression coefficient −7.7 [95% CI −16.2, 0.8] and −3.2 [−6.6, 0.2], respectively). Conclusions Extremely preterm adolescents who received postnatal dexamethasone in the newborn period had smaller total brain tissue volumes than those who did not receive postnatal dexamethasone, particularly white matter, thalami, and basal ganglia. Vulnerability of brain tissues or structures associated with postnatal dexamethasone varies by structure and persists into adolescence. PMID:24332820

Preterm birth remains the leading cause of neonatal mortality and morbidity worldwide. There are currently few effective therapies and therefore an urgent need for novel treatments. Although there is much focus on trying to alter gestation of delivery, the primary aim of preterm birth prevention therapies should be to reduce prematurity related mortality and morbidity. Given the link between intrauterine infection and inflammation and preterm labour (PTL), we hypothesized that administration of lipoxins, key anti-inflammatory and pro-resolution mediators, could be a useful novel treatment for PTL. Using a mouse model of infection-induced PTL, we investigated whether 15-epi-lipoxin A4 could delay lipopolysaccharide (LPS)-induced PTL and reduce pup mortality. On D17 of gestation mice (n = 9-12) were pretreated with vehicle or 15-epi-lipoxin A4 prior to intrauterine administration of LPS or PBS. Although pretreatment with 15-epi-lipoxin A4 did not delay LPS-induced PTL, there was a significant reduction in the mortality amongst prematurely delivered pups (defined as delivery within 36 h of surgery) in mice treated with 15-epi-lipoxin A4 prior to LPS treatment, compared with those receiving LPS alone (P < 0.05). Quantitative real-time (QRT)-PCR analysis of utero-placental tissues harvested 6 h post-treatment demonstrated that 15-epi-lipoxin A4 treatment increased Ptgs2 expression in the uterus, placenta and fetal membranes (P < 0.05) and decreased 15-Hpgd expression (P < 0.05) in the placenta and uterus, suggesting that 15-epi-lipoxin A4 may regulate the local production and activity of prostaglandins. These data suggest that augmenting lipoxin levels could be a useful novel therapeutic option in the treatment of PTL, protecting the fetus from the adverse effects of infection-induced preterm birth.

We conducted a systematic review to examine first generation immigrant adolescents' likelihood of experiencing bullying, violence, and suicidal behaviours compared to their later-generation and native born counterparts, and to identify factors that may underlie these risks. Eighteen studies met full inclusion criteria. First generation immigrant adolescents experience higher rate of bullying and peer aggression compared to third generation and native counterparts. Refugee status and advanced parental age were associated with increased parent to child aggression among South East Asians. Family cohesion was associated with lower rates of violence. Suicidal ideation was lower across most immigrant adolescents' ethnicities, with the exception of Turkish and South Asian Surinamese female adolescents in the Netherlands. Bullying and peer aggression of immigrant children and adolescents and potential mitigating factors such as family cohesion warrant research and program attention by policymakers, teachers and parents.

Children born very preterm (≤ 32 weeks gestation) exhibit greater internalizing (anxious/depressed) behaviors compared to term-born peers as early as 2 years corrected age (CA); however, the role of early stress in the etiology of internalizing problems in preterm children remains unknown. Therefore, we examined the relationship between neonatal pain and internalizing behavior at 18 months CA in children born very preterm and examined whether parent behavior and stress moderated this relationship. Participants were 145 children (96 very preterm, 49 full term) assessed at 18 months CA. Neonatal data were obtained from medical and nursing chart review. Neonatal pain was defined as the number of skin-breaking procedures. Cognitive ability was measured with the Bayley Scales of Infant Development II. Parents completed the Parenting Stress Index III, Child Behavior Checklist 1.5-5, and participated in a videotaped play session with their child, which was coded using the Emotional Availability Scale IV. Very preterm children displayed greater Internalizing behaviors compared to full-term control children (P=.02). Parent Sensitivity and Nonhostility moderated the relationship between neonatal pain and Internalizing behavior (all P<.05); higher parent education (P<.03), lower Parenting Stress (P=.001), and fewer children in the home (P<.01) were associated with lower Internalizing behavior in very preterm children, after adjusting for neonatal medical confounders, gender, and child cognitive ability (all P>.05). Parent Emotional Availability and stress were not associated with Internalizing behaviors in full-term control children. Positive parent interaction and lower stress appears to ameliorate negative effects of neonatal pain on stress-sensitive behaviors in this vulnerable population. PMID:23748079
Prematurity is by far the commonest cause of neonatal morbidity and mortality. The management of premature labour is empirical because little is understood about the mechanism of labour. Effective uterine relaxant drugs have an important, albeit minor role. Phototherapy has reduced the complications of neonatal hyperbilirubinemia, and the beneficial effect of antepartum corticosteroid therapy in minimizing the risk of respiratory distress syndrome is now convincing. Prophylactic antibiotic therapy in premature rupture of the membranes does not alter perinatal mortality, although postpartum maternal morbidity is reduced. The introduction of neonatal intensive care units has improved the survival rate of premature infants. Sound clinical judgement remains the mainstay in the management of premature labour. PMID:4217

Weight gain is common after implantation of continuous-flow ventricular assist devices. Obesity can have a significant negative impact on mobility. For adolescents with Becker muscular dystrophy (BMD), for whom the ability to ambulate often persists into the mid-3rd decade, preservation of functional ability is critical. We report two cases of Thoratec HeartMate II left ventricular assist device (LVAD) implantation in adolescents with BMD for whom postoperative weight gain contributed significantly to an accelerated loss of ambulation and, in one case, driveline fracture in the context of repeated falls. As LVADs become an increasingly common therapy for endstage heart failure in adolescents with BMD, care must be focused not only on maintenance of device functionality, but also on management of aggressive weight, and preservation of ambulation, and skeletal muscle strength.

Aims To assess the cognitive and behavioral aspects of executive functioning (EF) and learning skills in extremely preterm (EPT) children compared with term control children aged 10 to 15 years. Methods A total of 132 of 134 (98% of all eligible survivors) EPT children born at the 2 Swedish regional tertiary care centers from 1992 to 1998 (mean age = 12 years, mean birth weight = 718 g, and mean gestational age = 24.4 weeks) and 103 matched term controls were assessed. General intelligence was assessed using the Wechsler Intelligence Scale for Children (WISC-III-R), and cognitive aspects of EF were analyzed using EF-sensitive subscales of the WISC-III-R and Tower test of the Delis-Kaplan Executive Function Scale (D-KEFS). Behaviors related to EF and learning skills were assessed using the Five to Fifteen questionnaire, which is a validated parent and teacher instrument. Academic performance in school was assessed by teachers’ responses on Achenbach’s Teachers Report Form. Analyses performed included multivariate analyses of covariance (ANCOVA and MANCOVA) and logistic regression analyses. Results The EPT children displayed significant deficits in cognitive aspects of EF compared with the controls, exhibiting decreases on the order of 0.9 SD to 1.2 SD for tasks of verbal conceptual reasoning, verbal and non-verbal working memory, processing speed and planning ability (P <0.001 for all). After excluding the children with major neurosensory impairment (NSI) or a Full Scale intelligence quotient (FSIQ) of < 70, significant differences were observed on all tests. Compared with controls, parents and teachers of EPT children reported significantly more EF-related behavioral problems. MANCOVA of teacher-reported learning skills in children with FSIQ >70 and without major NSI revealed no interactions, but significant main effects were observed for the behavioral composite executive function score, group status (EPT vs control) and FSIQ, for which all effect sizes were

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

This study examined proximal risk and protective factors that contribute to academic achievement among 130 Latino students. Participating students were 56.2% female and 35.3% foreign-born (mean age = 11.38, SD = .59). Acculturative stress, immigrant status, child gender, parental monitoring, traditional cultural values, mainstream values, and English language proficiency were explored in relation to academic achievement. Higher levels of parental monitoring, English language proficiency, and female gender were associated with higher grades, while mainstream values were associated with lower grades. In addition, a significant interaction between acculturative stress and immigrant status was found, such that higher acculturative stress was related to poorer grades for U.S.-born students in particular. Thus, parental monitoring and female gender are potential protective factors, while identification with mainstream values and low English language proficiency are risk factors for poor grades. U.S.-born students may be particularly vulnerable to the effects of acculturative stress. PMID:25983352

Cerebral disturbances observed in premature infants are analyzed. These disturbances are a consequence of developmental slowdown and are associated with the pathological immaturity of the brain structures. On condition an active pathogenetic therapy is given these disturbances may gradually regress. On the basis of long-term observations of 600 prematurely born infants the authors describe the following clinical syndromes: muscular hypotonicity lasting up to 4-5 months and followed with a rise of the tone; the syndrome of "paretic hands" observed during the first two months of life; a hypertensive-hydrocephalic syndrome combined with a rise of the neuro-reflectory excitability; the syndrome of psychomotor development retardation followed at an age of over 1.5 to 2 years by complete recovery or minimal cerebral insufficiency with belated development of motor speech and neurosis-like reactions.

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

Adolescent survivors of preterm birth experience persistent functional problems that negatively impact academic outcomes, even when standardized measures of cognition and language suggest normal ability. In this fMRI study, we compared the neural activation supporting auditory sentence comprehension in two groups of adolescents (ages 9-16 years); sentences varied in length and syntactic difficulty. Preterms (n=18, mean gestational age 28.8 weeks) and full terms (n=14) had scores on verbal IQ, receptive vocabulary, and receptive language tests that were within or above normal limits and similar between groups. In early and late phases of the trial, we found interactions by group and length; in the late phase, we also found a group by syntactic difficulty interaction. Post hoc tests revealed that preterms demonstrated significant activation in the left and right middle frontal gyri as syntactic difficulty increased. ANCOVA showed that the interactions could not be attributed to differences in age, receptive language skill, or reaction time. Results are consistent with the hypothesis that preterm birth modulates brain-behavior relations in sentence comprehension as task demands increase. We suggest preterms' differences in neural processing may indicate a need for educational accommodations, even when formal test scores indicate normal academic achievement. PMID:22682901

In this fMRI study, we compared the neural activation supporting auditory sentence comprehension in two groups of adolescents (ages 9–16 years); sentences varied in length and syntactic difficulty. Preterms (n = 18, mean gestational age 28.8 weeks) and full terms (n = 14) had scores on verbal IQ, receptive vocabulary, and receptive language tests that were within or above normal limits and similar between groups. In early and late phases of the trial, we found interactions by group and length; in the late phase, we also found a group by syntactic difficulty interaction. Post hoc tests revealed that preterms demonstrated significant activation in the left and right middle frontal gyri as syntactic difficulty increased. ANCOVA showed that the interactions could not be attributed to differences in age, receptive language skill, or reaction time. Results are consistent with the hypothesis that preterm birth modulates brain-behavior relations in sentence comprehension as task demands increase. We suggest preterms’ differences in neural processing may indicate a need for educational accommodations, even when formal test scores indicate normal academic achievement. PMID:22682901

Objective. To determine relative influences of intrauterine growth restriction (IUGR) and preterm birth on risks of cardiovascular, renal, or metabolic dysfunction in adolescent children. Study Design. Retrospective cohort study. 71 periadolescent children were classified into four groups: premature small for gestational age (SGA), premature appropriate for gestational age (AGA), term SGA, and term AGA. Outcome Measures. Systolic blood pressure (SBP), augmentation index (Al), glomerular filtration rate (GFR) following protein load; plasma glucose and serum insulin levels. Results. SGA had higher SBP (average 4.6 mmHg) and lower GFR following protein load (average 28.5 mL/min/1.73 m2) than AGA. There was no effect of prematurity on SBP (P = .4) or GFR (P = .9). Both prematurity and SGA were associated with higher AI (average 9.7%) and higher serum insulin levels 2 hr after glucose load (average 15.5 mIU/L) than all other groups. Conclusion. IUGR is a more significant risk factor than preterm birth for later systolic hypertension and renal dysfunction. Among children born preterm, those who are also SGA are at increased risk of arterial stiffness and metabolic dysfunction. PMID:21197428

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, because therapy and supportive care continue to change, the outcomes of extremely low birth weight infants are ever evolving. Efforts to minimize injury, preserve growth, and identify interventions focused on antioxidant and anti-inflammatory pathways are now being evaluated. Thus, treating and preventing long-term deficits must be developed in the context of a "moving target." PMID:25988638

The energy density (ED; kcal/g) of foods, when manipulated in the laboratory, affects short-term energy intake. The aim of this study was to examine if, when given a choice, dietary ED (foods only) and energy intake (expressed as a percentage of subjects’ estimated daily energy requirement) at a self-selected, single meal differs for teens born with a different familial predisposition to obesity and as a function of their sex. Subjects (13 males, 17 females) were 12 years of age and born at high-risk (HR; n = 15) or low-risk (LR; n = 15) for obesity based on maternal pre-pregnancy body mass index (BMI; kg/m2). The buffet meal, served for lunch and consumed ad libitum, consisted of a variety of foods and beverages with a range in ED. HR subjects consumed a more energy-dense meal (foods only) than LR subjects (1.84 vs. 1.42 kcal/g; P = 0.02) and males consumed a more energy-dense meal than females (1.83 vs. 1.43 kcal/g; P = 0.03). Total energy intake, when expressed as a percentage of subjects’ daily EER, did not differ between HR and LR subjects (42% vs. 33%; P = 0.16). Males, compared to females, consumed ∼ 59% more energy from foods and beverages during the meal (46 vs. 29%; P = 0.008). During a single multi-item lunch meal, teens with a familial predisposition to obesity and males, independent of their obesity risk status, self-selected a more energy-dense meal. Familial risk for obesity, through either genetic or environmental pathways, may facilitate a more energy-dense diet. PMID:19778749

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

OBJECTIVE: To compare thoracic musculoskeletal static alterations in adolescents born prematurely with those born at term and investigate neonatal and post-neonatal variables associated with thoracic alterations. METHOD: This is a cross-sectional study with 57 adolescents aged 10-15 years born prematurely and 57 adolescents born at term paired by gender and age. Photographs of the head and thorax in the front, back, and right side views were studied using a computer program. The two groups were compared in regards to: elevation of clavicles, elevation of shoulders, protrusion of the head, and anteroposterior and mediolateral thoracic length. Factor associated with thoracic disorders were evaluated by linear regression analysis. RESULTS: The Preterm group had mean gestational age of 32.0±2.8 weeks and the birth weight was 1462±338 and 3342±430 g for the Preterm and Term adolescents, respectively. Preterm adolescents had higher elevation of the left shoulder (22.7±5.4o vs. 20.6±5.3o;sim, p=0.038) and the right shoulder (22.2±4.4o vs. 18.5±5.7o; p<0.001). Smaller protrusion of the head (27.8±6.1o vs. 32.4±7.9o; p=0.008), mediolateral thoracic length (22.9±2.3 cm vs. 25.1±3.1 cm; p<0.001) and anteroposterior thoracic length (19.7±2.2 cm vs. 21.1±3.4 cm; p<0.001) were found in preterm adolescents. By multiple regression analysis, factors associated with higher shoulder elevation were birth weight <1500 g (p<0.001) and mechanical ventilation during neonatal period >5 days (p=0.009). CONCLUSION: Adolescents born prematurely presented greater thoracic musculoskeletal static alterations compared to those born at term. Factors associated with these alterations were: very low birth weight and longer duration of mechanical ventilation in the neonatal unit. PMID:25651130

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

The improved survival of extremely premature infants has generated intense interest in the quality of life of the survivors. This review focuses on the major long-term complications of prematurity (developmental disability, retinopathy of prematurity, chronic lung disease) and concludes with an overview of the broader spectrum of morbidity. Severe impairment (cerebral palsy, mental retardation, retrolental fibroplasia, severe chronic lung disease) fortunately occurs in a small proportion of survivors. However, the prevalence of the lesser morbidities (minimal cerebral dysfunction/learning disability, poor growth, postneonatal illnesses, rehospitalization) is less clearly defined. These problems all have an impact on families, and on medical and educational services. PMID:2935764
Background Pregnancy in adolescents is a worldwide health problem and has been mostly common in poor populations. It is not clear if socioeconomic or biological factors are the main determinants of perinatal adverse outcomes in pregnant adolescents. Adolescents under 15 years old may present a high growth rate which may contribute to impair fetal growth. Our aim is to compare perinatal characteristics among early (aged 10 to 14 years) and late (aged 15 to 19 years) pregnant adolescents. Methods A cross-sectional study was performed using data from Pernambuco State 2009, obtained from DATASUS/SISNAC, a Brazilian Government, open-access public health database. Maternal and neonatal outcomes were compared between early (aged 10–14 years) and late (aged 15–19 years) pregnant adolescents. Family income was compared between early and late pregnant adolescents using a sample of 412 subjects evaluated at Instituto de Medicina Integral Prof. Fernando Figueira (IMIP) during 2011. Statistical comparisons were made using the chi-square test was used with a significant level of 0.05; bivariate and multivariate analysis were performed. This project was approved by the Institutional Ethics Review Board. Results Data from 31,209 pregnant adolescents were analyzed. 29,733 (95.2%) were aged 15 to 19 years and 1,476 (4.7%) were aged 10 to 14 years. There were significant differences with respect to marital status, education level and number of prenatal visits of mothers aged 10 to 14 years compared to 15 to 19 years. Of importance, early adolescents had a greater rate of neonates born premature and with low birth weight. Prematurity and low birth weight remained statistically significant after multivariate analysis. Conclusions Early aged adolescents may have an increased risk of prematurity and low birth weight. These findings highlight the potential role of biological factors in newborn outcomes in pregnant adolescents. PMID:23009715

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

Epidemiological studies indicate that children born small for gestational age (SGA) have an increased risk of metabolic and cardiovascular disorders as adults. This suggests that foetal undernutrition leads to permanent metabolic alterations, which predispose to metabolic abnormalities upon exposure to environmental factors such as low physical activity and/or high-energy intake in later life (thrifty phenotype hypothesis). However, this relationship is not restricted to foetal undernutrition or intrauterine growth retardation, but is also found for children born premature, or for high birth weight children. Furthermore, early post-natal nutrition, and more specifically catch-up growth, appear to modulate cardiovascular risk as well. Intrauterine growth retardation can be induced in animal models by energy/protein restriction, or ligation of uterine arteries. In such models, altered glucose homeostasis, including low beta-cell mass, low insulin secretion and insulin resistance is observed after a few weeks of age. In humans, several studies have confirmed that children born SGA have insulin resistance as adolescents and young adults. Alterations of glucose homeostasis and increased lipid oxidation can indeed be observed already in non-diabetic children born SGA at early pubertal stages. These children also have alterations of stature and changes in body composition (increased fat mass), which may contribute to the pathogenesis of insulin resistance. Permanent metabolic changes induced by foetal/early neonatal nutrition (metabolic inprinting) may involve modulation of gene expression through DNA methylation, or alterations of organ structure. It is also possible that events occurring during foetal/neonatal development lead to long-lasting alterations of the hypothalamo-pituitary-adrenal axis or the hypothalamo-pituitary-insulin-like growth factor-1 axis.

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

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

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.

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

The first epidemiological studies showing a link between low birth weight and chronic diseases in adults did not distinguish the origins of low birth weight. A low birth weight may be the result of a premature birth. It can also be caused by an intrauterine growth restriction (IUGR). A child can be both preterm and IUGR. It is clear now that prematurity is an independent risk factor for programming chronic adult diseases. However, unlike adults born IUGR, adults born prematurely do not have an increased risk to develop metabolic syndrome (dyslipidemia or obesity). An increased risk of neurodevelopmental and psychiatric morbidity and hypertension is found after a premature birth. Mechanisms of chronic diseases programming are multiple: they involve both the cause of prematurity and IUGR such as infection / inflammation or placental insufficiency, but also consequences for therapeutic or nutritional strategies needed to support these children. This chapter describes the possible prevention of perinatal programming of noncommunicable diseases. PMID:26850610

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

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

This article is a review on different aspects of premature ovarian failure (POF) defined as the development of hypogonadism in women before 40 years of age. The review will discuss the etiopathogeny, autoimmune and iatrogenic causes, abnormalities of chromosome X, as well as clinical manifestations, diagnosis, and treatment. Most of the women with this disorder do not have menstrual history, specific of POF development, but infertility associated with the diagnosis is the most problematic aspect of the disease.

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

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

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

Life-history data from a nationally representative survey of Australian women were used to examine discontinuation of contraceptive methods because of accidental pregnancy, side effects or dissatisfaction. The pill was the most successfully used method, with a first-year discontinuation rate of 10% for all three reasons. Side effects dominated the reasons for the premature discontinuation of both the pill and the IUD, while the reasons for discontinuing the condom stemmed equally from pregnancy and dissatisfaction with the method. Discontinuation of the diaphragm resulted largely from accidental pregnancy. Hazards models were used to identify the correlates of discontinuation of each method. Predictors of premature discontinuation reflect the availability of methods, physiological reactions to them and the social characteristics of their users. Discontinuation of the pill because of side effects or dissatisfaction was more likely among poorly educated women, non-Protestants and recent users, and less likely among teenagers. Discontinuation of the IUD was related entirely to physiological factors: Nulliparous women and users of unmedicated devices were at a greater risk than other women of accidental pregnancy, and nulliparous women were at greater risk of discontinuation associated with side effects. Nulliparous women were also more likely to discontinue the condom because of pregnancy, as were non-Protestants and the Australian-born. PMID:1612144

The continuing worldwide epidemic of retinopathy of prematurity (ROP), a leading cause of childhood visual impairment, strongly motivates further research into mechanisms of the disease. Although the hallmark of ROP is abnormal retinal vasculature, a growing body of evidence supports a critical role for the neural retina in the ROP disease process. The age of onset of ROP coincides with the rapid developmental increase in rod photoreceptor outer segment length and rhodopsin content of the retina with escalation of energy demands. Using a combination of non-invasive electroretinographic (ERG), psychophysical, and image analysis procedures, the neural retina and its vasculature have been studied in prematurely born human subjects, both with and without ROP, and in rats that model the key vascular and neural parameters found in human ROP subjects. These data are compared to comprehensive numeric summaries of the neural and vascular features in normally developing human and rat retina. In rats, biochemical, anatomical, and molecular biological investigations are paired with the non-invasive assessments. ROP, even if mild, primarily and persistently alters the structure and function of photoreceptors. Post-receptor neurons and retinal vasculature, which are intimately related, are also affected by ROP; conspicuous neurovascular abnormalities disappear, but subtle structural anomalies and functional deficits may persist years after clinical ROP resolves. The data from human subjects and rat models identify photoreceptor and post-receptor targets for interventions that promise improved outcomes for children at risk for ROP. PMID:19563909

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

Objective: Children of teen mothers exhibit adverse outcomes through adolescence. It is unclear whether these adverse outcomes extend to adulthood and apply to all of her children, or only those born when she was a teen. We examine the associations between young adult functioning and being born to a teen mother aged less than or equal to 20 years…

In spite of its high prevalence and long history, the ambiguity regarding the definition, epidemiology and management of premature ejaculation continues. Topical anesthetic creams and daily or on-demand selective serotonin reuptake inhibitor (SSRI) treatment forms the basis of pharmacotherapy for premature ejaculation today, in spite of low adherence by patients. Psychotherapy may improve the outcomes when combined with these treatment modalities. Tramadol and phosphodiesterase type 5 inhibitors have a limited role in the management of premature ejaculation. Further research is required to develop better options for the treatment of this common sexual disorder. PMID:25184045

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

Premature birth is highly prevalent and associated with neurodevelopmental delays and disorders. Adverse outcomes, particularly in children born before 32 weeks of gestation, have been attributed in large part to white matter injuries, often found in periventricular regions using conventional imaging. To date, tractography studies of white matter pathways in children and adolescents born preterm have evaluated only a limited number of tracts simultaneously. The current study compares diffusion properties along 18 major cerebral white matter pathways in children and adolescents born preterm (n = 27) and full term (n = 19), using diffusion magnetic resonance imaging and tractography. We found that compared to the full term group, the preterm group had significantly decreased FA in segments of the bilateral uncinate fasciculus and anterior segments of the right inferior fronto-occipital fasciculus. Additionally, the preterm group had significantly increased FA in segments of the right and left anterior thalamic radiations, posterior segments of the right inferior fronto-occipital fasciculus, and the right and left inferior longitudinal fasciculus. Increased FA in the preterm group was generally associated with decreased radial diffusivity. These findings indicate that prematurity-related white matter differences in later childhood and adolescence do not affect all tracts in the periventricular zone and can involve both decreased and increased FA. Differences in the patterns of radial diffusivity and axial diffusivity suggest that the tissue properties underlying group FA differences may vary within and across white matter tracts. Distinctive diffusion properties may relate to variations in the timing of injury in the neonatal period, extent of white matter dysmaturity and/or compensatory processes in childhood. PMID:26560745

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

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

Lung disease represents one of the most life-threatening conditions in prematurely born children. In the evaluation of the neonatal chest, the primary and most important diagnostic study is the chest radiograph. Since prematurely born children are very sensitive to radiation, those radiographs may lead to a significant radiation detriment. Knowledge of the radiation dose is therefore necessary to justify the exposures. To calculate doses in the entire body and in specific organs, computational models of the human anatomy are needed. Using medical imaging techniques, voxel phantoms have been developed to achieve a representation as close as possible to the anatomical properties. In this study two voxel phantoms, representing prematurely born babies, were created from computed tomography- and magnetic resonance images: Phantom 1 (1910 g) and Phantom 2 (590 g). The two voxel phantoms were used in Monte Carlo calculations (MCNPX) to assess organ doses. The results were compared with the commercially available software package PCXMC in which the available mathematical phantoms can be downsized toward the prematurely born baby. The simple phantom-scaling method used in PCXMC seems to be sufficient to calculate doses for organs within the radiation field. However, one should be careful in specifying the irradiation geometry. Doses in organs that are wholly or partially outside the primary radiation field depend critically on the irradiation conditions and the phantom model.

The prevalence of functional ovarian hyperandrogenism, hyperinsulinism and dyslipidaemia is increased in adolescent girls with a history of premature pubarche, defined as the appearance of pubic hair before the age of 8 years. The ovarian hyperandrogenism is characterized by clinical signs of androgen excess and an exaggerated ovarian 17-hydroxyprogesterone response to gonadotrophin-releasing hormone agonist stimulation. The hyperinsulinism and dyslipidaemia are detectable before and during pubertal development, and they are commonly accompanied by low serum levels of insulin-like growth factor binding protein-1 (IGFBP-1) and sex hormone binding globulin, and by an increased prevalence of anovulation from late adolescence onwards. In girls, premature pubarche, hyperinsulinism, low serum levels of IGFBP-1, dyslipidaemia, anovulation and hyperandrogenism (or various combinations of these conditions) have been related to reduced fetal growth, indicating that these constellations or sequences may have a prenatal origin. These findings suggest that premature pubarche in girls should no longer be regarded as merely a normal variant of development, but rather as a childhood marker pointing to an increased risk of a polyendocrine-metabolic disorder of prenatal origin.

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

Adrenarche means the morphological and functional change of the adrenal cortex leading to increasing production of adrenal androgen precursors (AAPs) in mid childhood, typically at around 5-8 years of age in humans. The AAPs dehydroepiandrosterone (DHEA) and its sulfate conjugate (DHEAS) are the best serum markers of adrenal androgen (AA) secretion and adrenarche. Normal ACTH secretion and action are needed for adrenarche, but additional inherent and exogenous factors regulate AA secretion. Inter-individual variation in the timing of adrenarche and serum concentrations of DHEA(S) in adolescence and adulthood are remarkable. Premature adrenarche (PA) is defined as the appearance of clinical signs of androgen action (pubic/axillary hair, adult type body odor, oily skin or hair, comedones, acne, accelerated statural growth) before the age of 8 years in girls or 9 years in boys associated with AAP concentrations high for the prepubertal chronological age. To accept the diagnosis of PA, central puberty, adrenocortical and gonadal sex hormone secreting tumors, congenital adrenal hyperplasia, and exogenous source of androgens need to be excluded. The individually variable peripheral conversion of circulating AAPs to biologically more active androgens (testosterone, dihydrotestosterone) and the androgen receptor activity in the target tissues are as important as the circulating AAP concentrations as determinants of androgen action. PA has gained much attention during the last decades, as it has been associated with small birth size, the metabolic and polycystic ovarian syndrome (PCOS), and thus with an increased risk for type 2 diabetes and cardiovascular diseases in later life. The aim of this review is to describe the known hormonal changes and their possible regulators in on-time and premature adrenarche, and the clinical features and possible later health problems associating with PA.

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

Pregnant women diagnosed with major depression were given 12 weeks of twice per week massage therapy by their significant other or only standard treatment as a control group. The massage therapy group women versus the control group women not only had reduced depression by the end of the therapy period, but they also had reduced depression and cortisol levels during the postpartum period. Their newborns were also less likely to be born prematurely and low birthweight, and they had lower cortisol levels and performed better on the Brazelton Neonatal Behavioral Assessment habituation, orientation and motor scales.

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

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. PMID:27090385

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

Contemporary clinical practice for the care of the prematurely born babies has markedly improved their rates of survival so that most of these babies are expected to grow up to live a healthy functional life. Since the clinical follow up is of short duration (years), only limited data are available to relate non-communicable diseases in adult life to events and interventions in the neonatal period. The major events that could have a programming effect include (1) Intrauterine growth restriction (2) Interruption of pregnancy with change in redox and reactive oxygen species injury (3) Nutritional and pharmacological protocols for Clinical care (4) Nutritional care in the first two years resulting in accelerated weight gain. The available data are discussed in the context of perturbations in one carbon (methyl transfer) metabolism and its possible programming effects. Although direct evidence for genomic methylation is not available, clinical and experimental data on impact of redox and ROS, of low protein intake, excess methionine load and vitamin A, on methyl transfers are reviewed. The consequences of antenatal and postnatal administration of glucocorticoids are presented. Analysis of the correlates of insulin sensitivity at older age, suggests that premature birth is the major contributor, and is compounded by gain in weight during infancy. We speculate that premature interruption of pregnancy and neonatal interventions by effecting one carbon metabolism may cause programming effects on the immature baby. These can be additive to the effects of intrauterine environment (growth restriction) and are compounded by accelerated growth in early infancy. PMID:25054678

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.

Adults who were born preterm with a very low birth weight have higher blood pressure and impaired glucose regulation later in life compared with those born at term. We investigated cardiometabolic risk factors in young adults who were born at any degree of prematurity in the Preterm Birth and Early Life Programming of Adult Health and Disease (ESTER) Study, a population-based cohort study of individuals born in 1985–1989 in Northern Finland. In 2009–2011, 3 groups underwent clinical examination: 134 participants born at less than 34 gestational weeks (early preterm), 242 born at 34–36 weeks (late preterm), and 344 born at 37 weeks or later (controls). Compared with controls, adults who were born preterm had higher body fat percentages (after adjustment for sex, age, and cohort (1985–1986 or 1987–1989), for those born early preterm, difference = 6.2%, 95% confidence interval (CI): 0.4, 13.2; for those born late preterm, difference = 8.0%, 95% CI: 2.4, 13.8), waist circumferences, blood pressure (for those born early preterm, difference = 3.0 mm Hg, 95% CI: 0.9, 5.1; for those born late preterm, difference = 1.7, 95% CI: −0.1, 3.4), plasma uric acid levels (for those born early preterm, difference = 20.1%, 95% CI: 7.9, 32.3; for those born late preterm, difference = 20.2%, 95% CI: 10.7, 30.5), alanine aminotransferase levels, and aspartate transaminase levels. They were also more likely to have metabolic syndrome (for those born early preterm, odds ratio = 3.7, 95% CI: 1.6, 8.2; for those born late preterm, odds ratio = 2.5, 95% CI: 1.2, 5.3). Elevated levels of conventional and emerging risk factors suggest a higher risk of cardiometabolic disease later in life. These risk factors are also present in the large group of adults born late preterm. PMID:25947956

Objective To assess childhood maltreatment as a risk factor for violent injuries and premature death in young adulthood and whether these associations are mediated by adolescent heavy drinking, hard drug use, hard drug selling, and violent offending. Design A prospective longitudinal study of boys followed from childhood into young adulthood. Setting Pittsburgh, Pennsylvania Participants A total 1,009 men of the Pittsburgh Youth Study Main Outcome Measures Premature deaths between ages 18 and 38 from the Social Security Death Index and self-reports of violent injuries inflicted by gunshot or knife between ages 18 and 28. Results Young men who experienced childhood maltreatment, compared to their counterparts who did not experience it, had a greater risk of violent injuries (relative risk [RR], 1.61; 95% confidence interval [CI], 1.01–2.35) and death (hazard ratio, [HR], 2.85; 95% CI, 1.37–5.93) during young adulthood. Adolescent violent offending and hard drug selling explained the association between childhood maltreatment and violent injuries, and violent offending partially accounted for the association between childhood maltreatment and premature death. Although adolescent violent offending predicted both outcomes, maltreated boys still had an increased risk of premature death (HR, 2.54; 95% CI, 1.21–5.34) after accounting for their adolescent violence. Conclusions Childhood maltreatment significantly predicts premature death and violent injuries during young adulthood. These associations are partially explained by adolescent involvement in violence and drug dealing. Targeted interventions for maltreated boys to reduce their involvement in adolescent deviant behaviors may help decrease their risks for later serious injuries and premature death. PMID:22566518

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

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

In some premature newborns, 7 months old and with less than 1 kg of body wheight, total parenteral nutrition is used for weeks, so that good antiseptics can cooperate to the prevention of nosocomial infections, associating the best biocide effects to the best topical tolerability. Details are reported on the biocide cutaneous properties of some chloro-derivates, as sodium hypochlorite and NaDCC, of ethyl and propyl alcohols, of chlorhexidine, of iodophors and also of triclosan and octenidine (even if these latter biocids are not normally available in Italy as cutaneous antiseptics).

The authors report the correlation between chest physiotherapy and increased risk of vitreous hemorrhage after laser photocoagulation therapy in patients with retinopathy of prematurity (ROP). Two premature neonates, the first born at 26 weeks and the second at 31 weeks gestational age, both underwent chest physiotherapy, the first for congenital cystic fibrosis and bronchopulmonary dysplasia and the second for premature alveolar atelectasis. Both were diagnosed as having ROP that necessitated laser photocoagulation treatment at 34 and 37 weeks, respectively. The first patient developed bilateral vitreous hemorrhage and bilateral cataracts. The second patient developed vitreous hemorrhage in one eye. Chest physiotherapy in neonates with ROP significantly increases the risk of hemorrhage after laser photocoagulation in an otherwise fragile retinal vasculature. PMID:23413823

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

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

Children born to early child bearers are more likely than other children to display problem behaviors or poor academic performance, but it is unclear whether early childbearing plays a causal role in these outcomes. Using multiple techniques to control for background factors, we analyze 2,908 young children and 1,736 adolescents and young adults…

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

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

Although anorectal malformations are often associated with urinary tract abnormalities, the association with posterior urethral valves is exceptionally rare. We report a unique case of a premature (35 gestational weeks) male neonate born with posterior urethral valves, bilateral dysplastic kidneys, and imperforate anus, successfully treated by Blocksom vesicostomy and left upper quadrant loop colostomy. The challenges involving placement of both stomas in a small abdominal wall of a 2200 g premature neonate are discussed. PMID:27015939

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

Summary: An estimated 750 million people are at risk of infections with food-borne trematodes, which comprise liver flukes (Clonorchis sinensis, Fasciola gigantica, Fasciola hepatica, Opisthorchis felineus, and Opisthorchis viverrini), lung flukes (Paragonimus spp.), and intestinal flukes (e.g., Echinostoma spp., Fasciolopsis buski, and the heterophyids). Food-borne trematodiases pose a significant public health and economic problem, yet these diseases are often neglected. In this review, we summarize the taxonomy, morphology, and life cycle of food-borne trematodes. Estimates of the at-risk population and number of infections, geographic distribution, history, and ecological features of the major food-borne trematodes are reviewed. We summarize clinical manifestations, patterns of infection, and current means of diagnosis, treatment, and other control options. The changing epidemiological pattern and the rapid growth of aquaculture and food distribution networks are highlighted, as these developments might be associated with an elevated risk of transmission of food-borne trematodiases. Current research needs are emphasized. PMID:19597009

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

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

Events causing stress responses during sensitive periods of rapid neurological development in childhood may be early determinants of all-cause premature mortality. Using a British birth cohort study of individuals born in 1958, the relationship between adverse childhood experiences (ACE) and mortality≤50 year was examined for men (n=7,816) and women (n=7,405) separately. ACE were measured using prospectively collected reports from parents and the school: no adversities (70%); one adversity (22%), two or more adversities (8%). A Cox regression model was carried out controlling for early life variables and for characteristics at 23 years. In men the risk of death was 57% higher among those who had experienced 2+ ACE compared to those with none (HR 1.57, 95% CI 1.13, 2.18, p=0.007). In women, a graded relationship was observed between ACE and mortality, the risk increasing as ACE accumulated. Women with one ACE had a 66% increased risk of death (HR 1.66, 95% CI 1.19, 2.33, p=0.003) and those with ≥2 ACE had an 80% increased risk (HR 1.80, 95% CI 1.10, 2.95, p=0.020) versus those with no ACE. Given the small impact of adult life style factors on the association between ACE and premature mortality, biological embedding during sensitive periods in early development is a plausible explanatory mechanism.

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

We report on modeling of a balloon borne mission to survey the 1-5 micron region with sensitivity close to the zodiacal light limits in portions of this band. Such a survey is compelling for numerous science programs and is complimentary to the upcoming Euclid, WFIRST and other orbital missions. Balloons borne missions offer much lower cost access and rapid technological implementation but with much less exposure time and increased backgrounds. For some science missions the complimentary nature of these is extremely useful. .

Tick-borne diseases in the United States include Rocky Mountain spotted fever, Lyme disease, ehrlichiosis, tularemia, babesiosis, Colorado tick fever, and relapsing fever. It is important for family physicians to consider these illnesses when patients present with influenza-like symptoms. A petechial rash initially affecting the palms and soles of the feet is associated with Rocky Mountain spotted fever, whereas erythema migrans (annular macule with central clearing) is associated with Lyme disease. Various other rashes or skin lesions accompanied by fever and influenza-like illness also may signal the presence of a tick-borne disease. Early, accurate diagnosis allows treatment that may help prevent significant morbidity and possible mortality. Because 24 to 48 hours of attachment to the host are required for infection to occur, early removal can help prevent disease. Treatment with doxycycline or tetracycline is indicated for Rocky Mountain spotted fever, Lyme disease, ehrlichiosis, and relapsing fever. In patients with clinical findings suggestive of tick-borne disease, treatment should not be delayed for laboratory confirmation. If no symptoms follow exposure to tick bites, empiric treatment is not indicated. The same tick may harbor different infectious pathogens and transmit several with one bite. Advising patients about prevention of tick bites, especially in the summer months, may help prevent exposure to dangerous vector-borne diseases. PMID:15999870

More than 150 arthropod-borne viruses are now recognized, and over 50 of these are known to produce human infections and disease. Among these viruses are those of the tick-borne Russian spring-summer complex, which is etiologically involved in a wide variety of human diseases of varying severity. The eight antigenically different members of this complex so far known are Russian spring-summer encephalitis, louping-ill, Central European encephalitis, Omsk haemorrhagic fever, Kyasanur Forest disease, Langat, Negishi and Powassan viruses. In his review of the problems posed by these viruses and of research on them, the author points out that, while this complex is distributed around the globe in the temperate zone of the northern hemisphere, the only serious tick-borne virus disease known in the tropics is Kyasanur Forest disease. It is probable, however, that there are other, unrecognized tick-borne viruses in the tropical areas of Asia, Africa and America of importance to human health, and that these will be brought to light as virological studies of diseases of now obscure etiology are pursued.

Vector-borne diseases have been the scourge of man and animals since the beginning of time. Historically, these are the diseases that caused the great plagues such as the 'Black Death' in Europe in the 14th Century and the epidemics of yellow fever that plagued the development of the New World. Others, such as Nagana, contributed to the lack of development in Africa for many years. At the turn of the 20th Century, vector-borne diseases were among the most serious public and animal health problems in the world. For the most part, these diseases were controlled by the middle of the 20th Century through the application of knowledge about their natural history along with the judicious use of DDT (dichlorodiphenyltrichloroethane) and other residual insecticides to interrupt the transmission cycle between arthropod and vertebrate host. However, this success initiated a period of complacency in the 1960s and 1970s, which resulted in the redirection of resources away from prevention and control of vector-borne diseases. The 1970s was also a time in which there were major changes to public health policy. Global trends, combined with changes in animal husbandry, urbanisation, modern transportation and globalisation, have resulted in a global re-emergence of epidemic vector-borne diseases affecting both humans and animals over the past 30 years.

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

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

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

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

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

Investigations of reproductive health within Latinos living in the United States suggest that sexual behaviors and contraception use practices vary by ethnicity and between foreign- and US-born adolescents. This article compares high-risk sexual behaviors and reproductive health among foreign-born Latinas, US-born Latinas, and US-born non-Latinas aged 15-24 years. We recruited 361 females from reproductive health clinics in the San Francisco Bay Area of California between 1995 and 1998; these women completed an interview that assessed sexual risk behaviors and history of pregnancy, abortion, and sexually transmitted infections. Current chlamydial and gonococcal infections were detected through biological testing. Among participants aged 15-18 years, US-born Latinas were more likely to have been pregnant (odds ratio [OR] comparing US-born Latinas and US-born non-Latinas = 3.9, 95% confidence interval [CI] 1.3, 11.4), whereas among respondents aged 19-24 years, foreign-born Latinas were more likely to have been pregnant than US-born Latinas (OR = 11.3, 95% CI 1.0, 130.8) and US-born non-Latinas (OR = 64.2, 95% CI 9.9, 416.3). US-born Latinas were most likely to have had an abortion (OR comparing US-born Latinas and US-born non-Latinas = 2.0, 95% CI 0.9, 4.7). They were also most likely to have chlamydial infection at study enrollment (8.2% prevalence compared to 2.2% and 1.0%for foreign-born Latinas and US-born non-Latinas, respectively; P =.009). Reproductive health differences between foreign and US-born females and within the US-born population warrant further examination and highlight the need for targeted prevention. PMID:11796809

OBJECTIVE 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. METHODS 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 8,060 children age 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. RESULTS 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 was 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. CONCLUSIONS 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. PMID:24401664

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

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

(1) Background: Assessing the quality of growth in premature infants is important in order to be able to provide them with optimal nutrition. The Pea Pod device, based on air displacement plethysmography, is able to assess body composition of infants. However, this method has not been sufficiently evaluated in premature infants; (2) Methods: In 14 infants in an age range of 3–7 days, born after 32–35 completed weeks of gestation, body weight, body volume, fat-free mass density (predicted by the Pea Pod software), and total body water (isotope dilution) were assessed. Reference estimates of fat-free mass density and body composition were obtained using a three-component model; (3) Results: Fat-free mass density values, predicted using Pea Pod, were biased but not significantly (p > 0.05) different from reference estimates. Body fat (%), assessed using Pea Pod, was not significantly different from reference estimates. The biological variability of fat-free mass density was 0.55% of the average value (1.0627 g/mL); (4) Conclusion: The results indicate that the Pea Pod system is accurate for groups of newborn, moderately premature infants. However, more studies where this system is used for premature infants are needed, and we provide suggestions regarding how to develop this area. PMID:27110820
Long chain polyunsaturated fatty acids (LCPUFA) including docosahexaenoic acid (DHA), are essential for normal vision and neurodevelopment. DHA accretion in utero occurs primarily in the last trimester of pregnancy to support rapid growth and brain development. Premature infants, born before this process is complete, are relatively deficient in this essential fatty acid. Very low birth weight (VLBW) infants remain deficient for a long period of time due to ineffective conversion from precursor fatty acids, lower fat stores, and a limited nutritional provision of DHA after birth. In addition to long- term visual and neurodevelopmental risks, VLBW infants have significant morbidity and mortality from diseases specific to premature birth, including bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC), and retinopathy of prematurity (ROP). There is increasing evidence that DHA has protective benefits against these disease states. The aim of this article is to identify the unique needs of premature infants, review the current recommendations for LCPUFA provision in infants, and discuss the caveats and innovative new ways to overcome the DHA deficiency through postnatal supplementation, with the long term goal of improving morbidity and mortality in this at risk population.

Obesity and aging share an impaired immune system and oxidative and inflammatory stress. Therefore, the hypothesis of obesity as a possible model of premature immunosenescence has been proposed. In this study, we investigated whether adult obese mice, as a consequence of being fed with a fat-rich diet during their adolescence, showed premature immunosenescence and if this was aggravated with aging. Peritoneal cell suspensions were obtained when ICR/CD1 obese female mice were adults (28 weeks) and old (72 weeks), and several functions and antioxidant defenses were evaluated. The results showed that the chemotaxis of both macrophages and lymphocytes, phagocytosis of macrophages, activity of natural killer cells, proliferative response of lymphocytes, interleukin-1β, tumor necrosis factor-alpha, interleukin-6, interleukin-2, and interleukin-10 released in leukocyte cultures, as well as antioxidant and oxidant capacity were significantly impaired in adult obese mice with respect to adult nonobese mice, with values similar to those in chronologically old mice. When these obese animals grew older, although having been fed with a standard diet, they showed a higher deterioration of their immune functions in comparison with the old control group. In conclusion, these results demonstrate that a high fat intake during adolescence can produce an obesity state in adult age associated with a premature immunosenescence, which is aggravated through aging.

For about two weeks in 1995, the balloon-borne Flare Genesis Experiment will continuously observe the Sun well above the turbulent, image-blurring layers of the Earth's atmosphere. The polarization-free 80 cm telescope will supply images to a liquid-crystal based vector magnetograph, which will measure magnetic features at a resolution of 0.2 arcsec. An electrically tunable lithium-niobate Fabry-Perot provides a spectral resolution of about 0.015 nm. In a follow-up series of Antarctic balloon flights, the Flare Genesis Experiment (FGE) will provide unprecedented details about sunspots, flares, magnetic elements, filaments, and the quiet solar atmosphere.

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.

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

The objective of this study was to analyse trends in socioeconomic inequalities in premature mortality in Barcelona from 1992 to 2011, accounting for population changes. We conducted a repeated cross-sectional study of the Barcelona population (25-64 years) using generalized linear mixed models for trend analysis, and found that socioeconomic inequalities in premature mortality persisted between neighbourhoods, but tended to diminish. However, the reduction in inequality was related to an increase in the number of foreign-born individuals mainly in socioeconomic disadvantaged neighbourhoods, in which the decrease in premature mortality was more marked. To study trends in geographical inequalities in mortality, it is essential to understand demographic changes occurred in different places related to local levels of deprivation. PMID:27105035

Tick-borne encephalitis (TBE) is one of the most dangerous human infections occurring in Europe and many parts of Asia. The etiological agent Tick-borne encephalitis virus (TBEV), is a member of the virus genus Flavivirus, of the family Flaviviridae. TBEV is believed to cause at least 11,000 human cases of encephalitis in Russia and about 3000 cases in the rest of Europe annually. Related viruses within the same group, Louping ill virus (LIV), Langat virus (LGTV) and Powassan virus (POWV), also cause human encephalitis but rarely on an epidemic scale. Three other viruses within the same group, Omsk hemorrhagic fever virus (OHFV), Kyasanur Forest disease virus (KFDV) and Alkhurma virus (ALKV), are closely related to the TBEV complex viruses and tend to cause fatal hemorrhagic fevers rather than encephalitis. This review describes the clinical manifestations associated with TBEV infections, the main molecular-biological properties of these viruses, and the different factors that define the incidence and severity of disease. The role of ticks and their local hosts in the emergence of new virus variants with different pathogenic characteristics is also discussed. This review also contains a brief history of vaccination against TBE including trials with live attenuated vaccine and modern tendencies in developing of vaccine virus strains. PMID:12615309
This paper is based on work published in . It describes a triple slit experiment using single photons that has been used to provide a bound on one of the most fundamental axioms of quantum mechanics i.e. Born's rule for probabilities . In spite of being one of the most successful theories which describes various natural phenomena, quantum mechanics has enough intricacies and "weirdness" associated with it which makes many physicists believe that it may not be the final theory and hints towards the possibility of more generalized versions. Quantum interference as shown by a double slit diffraction experiment only occurs from pairs of paths. Even in multi-slit versions, interference can only occur between pairs of possibilities and increasing the number of slits does not increase the complexity of the theory that still remains second-order. However, more generalized versions of quantum mechanics may allow for multi-path i.e. higher than second order interference. This experiment also provides a bound on the magnitude of such higher order interference. We have been able to bound the magnitude of three-path interference to less than 10-2 of the expected two-path interference, thus ruling out third and higher order interference and providing a bound on the accuracy of Born's rule.

Non-invasive techniques, include nasal continuous positive airways pressure (nCPAP), nasal intermittent positive pressure ventilation (NIPPV) and heated, humidified, high flow cannula (HHFNC). Randomised controlled trials (RCTs) of nCPAP versus ventilation have given mixed results, but one demonstrated fewer respiratory problems during infancy. Meta-analysis demonstrated NIPPV rather than nCPAP provided better support post extubation. After extubation or initial support HHFNC has similar efficacy to CPAP. Invasive techniques include those that synchronise inflations with the patient's respiratory efforts. Assist control/ synchronised intermittent mandatory ventilation compared to non triggered modes only reduce the duration of ventilation. Further data are required to determine the efficacy of proportional assist ventilation and neurally adjusted ventilatory assist. Other techniques aim to minimise volutrauma. RCTs of volume targeted ventilation demonstrated reductions in BPD and respiratory medication usage at follow-up. Prophylactic high frequency oscillatory ventilation does not reduce BPD, but is associated with superior lung function at school age. PMID:26698269

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

Assisted reproductive technologies (ART) predispose the offspring to vascular dysfunction, arterial hypertension, and hypoxic pulmonary hypertension. Recently, cardiac remodeling and dysfunction during fetal and early postnatal life have been reported in offspring of ART, but it is not known whether these cardiac alterations persist later in life and whether confounding factors contribute to this problem. We, therefore, assessed cardiac function and pulmonary artery pressure by echocardiography in 54 healthy children conceived by ART (mean age 11.5 ± 2.4 yr) and 54 age-matched (12.2 ± 2.3 yr) and sex-matched control children. Because ART is often associated with low birth weight and prematurity, two potential confounders associated with cardiac dysfunction, only singletons born with normal birth weight at term were studied. Moreover, because cardiac remodeling in infants conceived by ART was observed in utero, a situation associated with increased right heart load, we also assessed cardiac function during high-altitude exposure, a condition associated with hypoxic pulmonary hypertension-induced right ventricular overload. We found that, while at low altitude cardiac morphometry and function was not different between children conceived by ART and control children, under the stressful conditions of high-altitude-induced pressure overload and hypoxia, larger right ventricular end-diastolic area and diastolic dysfunction (evidenced by lower E-wave tissue Doppler velocity and A-wave tissue Doppler velocity of the lateral tricuspid annulus) were detectable in children and adolescents conceived by ART. In conclusion, right ventricular dysfunction persists in children and adolescents conceived by ART. These cardiac alterations appear to be related to ART per se rather than to low birth weight or prematurity. PMID:25979934

This study aimed to provide a more comprehensive picture of the prevalence of autism spectrum disorder (ASD) in a geographic cohort of extremely preterm born adolescents by using established diagnostic instruments in addition to screening instruments. 53 participants passed a screening procedure with two screening instruments and a diagnostic evaluation with a semi-structured assessment and a parent interview. 28 % of the adolescents had a community based clinical diagnosis of ASD. When research diagnoses were also taken into account, this rate increased to 40 %. Intellectual disability, language impairment and behavioural difficulties are characteristic for these children with ASD. This study is to our knowledge the first to use ASD-specific diagnostic instruments to confirm ASD diagnoses in extremely preterm born children in early adolescence. The study expands findings of previous research and raises the need for follow-up into late childhood and early adolescence. PMID:26546379

This study aimed to compare the adaptation of two groups of migrant Chinese adolescents with their nonmigrant peers. The migrant adolescents included 55 Chinese migrant adolescents who migrated to Australia (Chinese-Australian) and 111 China-born adolescents who migrated to Hong Kong (Chinese-Hong Kong). The nonmigrant adolescents included 157 Anglo-Australian adolescents residing in Australia and 456 Hong Kong-born Chinese adolescents residing in Hong Kong. There were three research questions in this study. First, would there be any differences in the adaptation of Chinese migrant adolescents in different societies of settlement? Second, would migrant adolescents experience more adaptation problems than nonmigrant adolescents? Third, would there be any differences in the adaptation of adolescents in the two societies, Australia and Hong Kong? It was hypothesized that: (1) mainland Chinese migrant adolescents in Hong Kong would experience more adaptation problems than Chinese migrant adolescents in Australia; (2) migrant adolescents would report better adaptation than nonmigrant adolescents; (3) adolescents in Hong Kong would report poorer adaptation than adolescents in Australia. The participants were requested to complete a questionnaire on various adaptation outcome measures including life satisfaction, self-esteem, psychological symptoms, academic satisfaction, and behaviour problems. The results indicated that Chinese-Australian adolescents reported better psychological adaptation but Chinese-Hong Kong adolescents reported better sociocultural adaptation. Adolescents resident in Australia reported higher psychological adaptation but lower sociocultural adaptation than those in Hong Kong. Migrant adolescents reported better psychological and sociocultural adaptation than their nonmigrant counterparts. The results were discussed in relation to the social and educational systems of the two societies. PMID:22029492

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

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

Introduction Although preterm birth is associated with respiratory morbidity in childhood, the role of family history of atopy and whether appropriate treatment has been instituted is unclear. Thus we assessed (i) the prevalence of respiratory symptoms, particularly wheezing, in childhood; (ii) evaluated the role of family history of atopy and mode of delivery, and (iii) documented the drug usage, all in preterm-born children compared to term-born control children. Methods We conducted a cross-sectional population-based questionnaire study of 1–10 year-old preterm-born children (n = 13,361) and matched term-born controls (13,361). Data (n = 7,149) was analysed by gestational groups (24–32 weeks, 33–34 weeks, 35–36 weeks and 37–43 weeks) and by age, <5 years old or ≥ 5 years. Main Results Preterm born children aged <5 years (n = 2,111, term n = 1,402) had higher rates of wheeze-ever [odds ratio: 2.7 (95% confidence intervals 2.2, 3.3); 1.8 (1.5, 2.2); 1.5 (1.3, 1.8) respectively for the 24–32 weeks, 33–34 weeks, 35–36 weeks groups compared to term]. Similarly for the ≥5 year age group (n = 2,083, term n = 1,456) wheezing increased with increasing prematurity [odds ratios 3.3 (2.7, 4.1), 1.8 (1.5, 2.3) and 1.6 (1.3, 1.9) for the three preterm groups compared to term]. At both age groups, inhaler usage was greater in the lowest preterm group but prematurity-associated wheeze was independent of a family history of atopy. Conclusions Increasing prematurity was associated with increased respiratory symptoms, which were independent of a family history of atopy. Use of bronchodilators was also increased in the preterm groups but its efficacy needs careful evaluation. PMID:27203564

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

Objective Despite the current prevalence of preterm births, no clear guidelines exist on the optimal mode of delivery. Our objective was to investigate the effects of mode of delivery on neonatal outcomes among premature infants in a large cohort. Study Design We applied a retrospective cohort study design to a database of 6,408 births. Neonates were stratified by birth weight and a composite score was calculated to assess neonatal outcomes. The results were then further stratified by fetal exposure to antenatal steroids, birth weight, and mode of delivery. Results No improvement in neonatal outcome with cesarean delivery (CD) was noted when subjects were stratified by mode of delivery, both in the presence or absence of antenatal corticosteroid administration. In the 1,500 to 1,999 g subgroup, there appears to be an increased risk of respiratory distress syndromes in neonates born by CD. Conclusion In our all-comers cohort, replicative of everyday obstetric practice, CD did not improve neonatal outcomes in preterm infants. PMID:27468363
Tick-borne encephalitis (TBE) is one of the most important viral infections of the human central nervous system. Approximately 10,000 cases of TBE are referred to hospitals in Europe and Asia each year. The TBE virus (TBEV) is mainly transmitted by tick bites but also occasionally by unpasteurized goat's milk. As in endemic areas on average only 1-3 % of ticks are infected with the TBEV and the clinical manifestation rate is approximately 33 %, only approximately 1 in every 100-300 tick bites leads to disease. The incubation period varies from 5-28 days and typically has a biphasic course of fever. The TBE manifests as meningitis in approximately 50 % of patients, as meningoencephalitis in 40 % and as encephalomyelitis in 10 %. The suspected diagnosis is confirmed by the demonstration of TBEV-specific IgM and IgG antibodies in serum and the presence of elevated cell counts in cerebrospinal fluid. No specific treatment for TBE is known but it can be successfully prevented by active immunization. PMID:27225401

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

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

Objective: ADHD and asthma are prevalent conditions in childhood, with complex pathophysiology involving genetic-environmental interplay. The study objective is to examine the prevalence of asthma in our ADHD population and explore factors that may increase the risk of developing asthma in children with ADHD. Methods: We retrospectively analyzed the presence of maternal stress during pregnancy and history of asthma in 201 children diagnosed with ADHD. Results: Chi-square analysis indicated significant higher presence of asthma in our ADHD sample compared to Quebec children, χ2(1, N = 201) = 15.37, P<0.001. Only prematurity and stress during pregnancy significantly predicted asthma in a logistic regression model, χ2(2)=23.70, P<0.001, with odds ratios of 10.6 (95% CI: 2.8–39.5) and 3.2 (95% CI: 1.4–7.3), respectively. Conclusion: Children with ADHD have a higher prevalence of asthma than the general Quebec pediatric population. Children with ADHD born prematurely and/or those whose mothers experienced stress during pregnancy have a significantly increased risk of developing asthma. The study highlights the importance of potentially offering social and psychological support to mothers who experienced stress during pregnancy and/or are at risk of delivering prematurely.

Background Effects of maternal employment for preschool children vary based on specific characteristics of the mother’s employment, the family’s economic status, and the mother’s attitudes about employment. However, there is limited research on a growing group of children at developmental risk—those born prematurely and living in a single-parent family. Objective To examine the effects of maternal employment and prematurity on child cognition and behavior in single-parent families. Methods Sixty preterm and 61 full-term preschool children were recruited through NICU admission records and birth records. Data were collected with the Kaufmann Assessment Battery for Children, Peabody Picture Vocabulary Test, Child Behavior Checklist, Parenting Stress Index, and the Life History Calendar. Results Greater hours employed was related to higher achievement and mental processing scores only. Less discrepancy between actual and desired employment was related to higher achievement, mental processing, and language scores and lower behavior scores. Prematurity was not related to child cognitive and behavioral performance. Only the relationship between discrepancy and language remained after statistical control. Conclusions The concerns about negative effects of maternal employment on young children may be overstated, especially in low-income, single-mother families. These findings are especially important in the context of welfare reform. PMID:11725936
