    Full Text Available Introduction. More and more survival of newborns with small or extremely small body mass at birth, as well as increasing percent of prematurely born babies, have emphasized the significance of intracranial haemorrhage problem. Prematurely born infants are under increased risk for strabismus, amblyopia, blinding and hearing loss. Objective. Establishing the frequency of sensory damages (damage of sight and hearing in prematurely born infants with various degrees of intracranial haemorrhage. Methods. The study is prospective, controlled and included 120 prematurely born infants with diagnosed four different grade intracranial haemorrhage on ultrasonic examination of the central nervous system. The study excluded prematurely born children from twin pregnancies with congenital malformations and stoppage of intrauterine growth. Ophthalmological examination was done at 9, 12, and 36 months of postnatal age. Audilogical examination was done after delivery, at 2 months of age. Results. There are statistically significant differences (p<0.01 related to the presence of strabismus among groups of examinees with vairious hemorrhage degrees. Strabismus was present only in one premature infant with 1st and in 10 children (33.3% with the 4th degree. Amblyopia occurred only among examinees with 4th degree hemorrhage. There were statistically significant differences (p<0.01 related to the finding of transitory otoacoustic emission of the left ear and the right ear among the groups. The finding of the right ear was not usual in 7 examinees from the 4th degree hemorrhage. The finding of the left ear was not usual in 1 examinee from the third and in 7 examinees from the fourth group. Conclusion. Prematurely born children with a higher degree intracranial hemorrhage have a greater risk for the loss of hearing and development of visual handicap.

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

    Objective Unexplained clitoromegaly is a rare but well recognised feature in girls born premature. Although detected at birth, girls may re-present during childhood to paediatric urologists and gynaecologists who should be aware of this condition. The aim of the study was to describe the clinical findings and management of a series of girls presenting with persistent congenital clitoromegaly associated with prematurity. Materials and methods This was a retrospective notes review set in a tertiary referral centre for Paediatric and Adolescent Gynaecology (PAG). Results Eight girls with a mean age of 6 years were seen over an eight year period. In all cases a Disorder of Sex Development (DSD) had been previously excluded. The main symptoms were discomfort or concern about appearance. On examination five girls had excess skin over the clitoris and three had enlarged corporal tissue. Management included reassurance and simple measures to ease discomfort. In two cases the parents requested referral to a paediatric urologist to consider clitoral surgery. Conclusion As survival rates for extreme prematurity improve, paediatric urologists and gynaecologists are likely to see more of these cases. Clinicians must be familiar with this condition to ensure children are managed appropriately. PMID:23619354

    Prematurity is a public health problem that calls to focus on its causes and consequences through a trans disciplinary approach. There are no studies analyzing premature birth from the perspective of individuals born preterm. To identify social representations associated with premature birth of individuals born preterm in the 1990s in Argentina. Twelve focus groups were conducted with individuals born preterm with a birth weightPrematurity is a significant element, especially in those who suffered major sequelae. Adolescents and youth give a warning on the negative effects caused by overprotective parents and reveal the possibility of redefining the challenges associated with their history of premature birth.

    A cohort of extremely prematurely born children and matched term controls was assessed at 5 years of age. The parents completed a questionnaire on their behavioral and social development. The purpose was to illuminate whether the children's general intellectual ability and parental sensitivity were...... associated with behavioral and social development. The index children exhibited more hyperactive behavior and had poorer social skills than the controls. Lower Full Scale IQ (FSIQ) was associated with outward reacting and hyperactive behavior and poorer social skills. Sensitive parenting was associated...... with less outward reacting and less hyperactive behavior. When controlling for differences in FSIQ and parental sensitivity, the index children persisted to have an increased risk of exhibiting hyperactive behavior but not poorer social skills.

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

    Adults born preterm at very low birth weight (VLBW; blood pressure than those born at term. It is not known whether all VLBW adults are at risk or whether higher blood pressure could be attributed to some of the specific conditions underlying or accompanying preterm birth. To identify possible risk or protective factors, we combined individual-level data from 9 cohorts that measured blood pressure in young adults born at VLBW or with a more stringent birth weight criterion. In the absence of major heterogeneity, we performed linear regression analysis in our pooled sample of 1571 adults born at VLBW and 777 controls. Adults born at VLBW had 3.4 mm Hg (95% confidence interval, 2.2-4.6) higher systolic and 2.1 mm Hg (95% confidence interval, 1.3-3.0) higher diastolic pressure, with adjustment for age, sex, and cohort. The difference in systolic pressure was present in men (1.8 mm Hg; 95% confidence interval, 0.1-3.5) but was stronger in women (4.7 mm Hg; 95% confidence interval, 3.2-6.3). Among the VLBW group, blood pressure was unrelated to gestational age, maternal smoking, multiple pregnancy, retinopathy of prematurity, or bronchopulmonary dysplasia. Blood pressure was higher than that of controls among VLBW adults unexposed to maternal preeclampsia. Among those exposed, it was even higher, especially if born appropriate for gestational age. In conclusion, although female sex and maternal preeclampsia are additional risk factors, the risk of higher blood pressure is not limited to any etiologic subgroup of VLBW adults, arguing for vigilance in early detection of high blood pressure in all these individuals. © 2016 American Heart Association, Inc.

    Full Text Available 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.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.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.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.

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

    The purpose was to study the effect of prematurity on the macula-disc centre distance and whether it could be used as a reference tool for determining the size of retinal features in prematurely born children by fundus photography. The macula-disc centre distance of the left eye was measured in pixels from digital fundus photographs taken from 27 prematurely born children aged 10-11 years with Topcon fundus camera. A conversion factor for Topcon fundus camera (194.98 pixel/mm for a 50° lens) was used to convert the results in pixels into metric units. The macula-disc centre distance was 4.74 mm, SD 0.29. No correlation between ametropia and the macula-disc centre distance was found (r = -0.07, p > 0.05). One child (subject 20) had high myopia and retinopathy of prematurity (ROP), and the macula-disc centre distance was longer than average (6.35 mm). The macula-disc centre distance in prematurely born children at the age of 10-11 years provides an easy-to-use reference tool for evaluating the size of retinal features on fundus photographs. However, if complications of ROP, for example temporal macular dragging or high ametropia, are present, the macula-disc centre distance is potentially altered and a personal macula-disc centre distance should be determined and used as a refined reference tool. © 2014 Acta Ophthalmologica Scandinavica Foundation.

    Objectives To use functional magnetic resonance imaging (fMRI) to test the hypothesis that subjects who were born prematurely develop alternative systems for processing language. Study design Subjects who were born prematurely (n = 14; 600-1250 g birthweight) without neonatal brain injury and 10 matched term control subjects were examined with a fMRI passive listening task of language, the Clinical Evaluation of Language Fundamentals (CELF) and portions of the Comprehensive Test of Phonological Processing (CTOPP). The fMRI task was evaluated for both phonologic and semantic processing. Results Although there were differences in CELF scores between the subjects born prematurely and control subjects, there were no significant differences in the CTOPP measures in the 2 groups. fMRI studies demonstrated that the groups differentially engaged neural systems known to process language. Children born at term were significantly more likely to activate systems for the semantic processing of language, whereas subjects born prematurely preferentially engaged regions that subserve phonology. Conclusions At 12 years of age, children born prematurely and children born at term activate neural systems for the auditory processing of language differently. Subjects born prematurely engage different networks for phonologic processing; this strategy is associated with phonologic language scores that are similar to those of control subjects. These biologically based developmental strategies may provide the substrate for the improving language skills noted in children who are born prematurely. PMID:17011320

    Palivizumab reduces the severity of respiratory syncytial virus infection in premature infants, but whether there is a protective effect beyond the preschool age is unknown. This study sought to assess the short- and long-term effects of palivizumab immunization on respiratory morbidity and pulmonary function at school age in children born extremely prematurely. Infants born before 29 weeks' gestation in 2000 to 2003 were assessed at school age by parental questionnaire, hospital chart review, and lung function tests. Children born immediately before the introduction of routine palivizumab prophylaxis were compared with age-matched children who received palivizumab prophylaxis during the first respiratory syncytial virus season. Sixty-three children with a mean age 8.9 years were included: 30 had received palivizumab and 33 had not (control subjects). The groups were similar in terms of gestational age, birth weight, need for mechanical ventilation, and oxygen supplementation. Fifty-three percent of the palivizumab group, compared with 39% of the control group, had bronchopulmonary dysplasia (P = .14). Wheezing occurred in the first 2 years of life in 27% of the palivizumab group and in 70% of control subjects (P = .008); respective hospitalization rates were 33% and 70% (P = .001). At school age, rates of hyperresponsiveness (provocative concentration leading to a 20% fall in FEV1 < 1 mg/mL) were 33% and 48%, respectively (P = .38). Spirometry, lung volumes, diffusion, and exhaled nitric oxide were within normal limits, with no significant differences between groups. Palivizumab prophylaxis was associated with reduced wheezing episodes and hospitalizations during the first 2 years of life in children born extremely prematurely. However, it did not affect pulmonary outcome at school age. Copyright © 2016 American College of Chest Physicians. Published by Elsevier Inc. All rights reserved.

    This study was conducted to investigate the prevalence of premature ejaculation (PE) in young Turkish men and to evaluate PE in a population having good physical and mental health. A total of 1230 healthy university graduates aged between 24 and 30 attending the police academy having no physical or mental problems were included in the study. To identify the presence of PE, the participants were asked to complete the premature ejaculation diagnostic tool (PEDT). The mean ages in the PE and non-PE group were 27.3 and 26.7 respectively. There was no statistically significant difference between the two groups concerning age, body mass index (BMI), smoking status and alcohol consumption (P > 0.05). The PE prevalence was found to be 9.2%. The mean PEDT score was calculated as 6.3. Of the participants, 92 scored 11 and higher (9.2%), 66 scored 9 and 10 (6.6%), and the remaining 842 obtained a score equal to or lower than 8 (84.2%). The lower prevalence of PE in young Turkish men compared to the results of studies in the literature can be attributed to the physical and mental well-being of the participants. This study showed that the prevalence of PE in young men with good physical and mental health is lower than that found in the literature.

    Despite technological advances in neonatology, premature children are still susceptible to disruptions in neurological development. The current study aimed to analyze the factors that influence motor development in prematurely born school-aged children in Brazil. This cross-sectional study involved 100 "apparently normal" children, aged 8-10 years, born at less than 35 weeks of gestation or with birth weightmotor development was assessed using the Movement Assessment Battery for Children (MABC-2). The children's neuropsychological and academic performance was assessed with the Token Test (TT) and Teste de Desempenho Escolar (TDE), respectively. Parents answered questions regarding the child's clinical history and behavior using the Strengths and Difficulties Questionnaire (SDQ) and family environment resources (RAF). Hierarchical multivariate analyses revealed that 39% of the children scored lower on the MABC-2, as compared to that expected for their age (manual dexterity: 49%; balance: 35%; throwing/catching a ball: 26%). Multivariate analysis indicated that the lower the birth weight, the maternal age at childbirth, and the RAF score, the greater was the chance of impairment on the MABC-2 scores. The probability of having an impairment MABC-2 scores was four times higher when the mother was not employed. We also found associations between MABC-2 scores and the tasks of tying shoes and opening/closing zippers and buttons. Factors related to children's home environments and birth weight are associated with deficient motor performance in prematurely born Brazilian school-aged children. Deficient motor skills were also associated with difficulty in performing functional tasks requiring greater manual dexterity.

    This study examined the neural correlates of intentional and automatic number processing (indexed by number comparison and physical Stroop task, respectively) in 6- and 7-year-old children born prematurely. Behavioral results revealed significant numerical distance and size congruity effects. Imaging results disclosed (1) largely overlapping fronto-parietal activation for intentional and automatic number processing, (2) a frontal to parietal shift of activation upon considering the risk factors gestational age and birth weight, and (3) a task-specific link between math proficiency and functional magnetic resonance imaging (fMRI) signal within distinct regions of the parietal lobes-indicating commonalities but also specificities of intentional and automatic number processing.

    Developmental hip dysplasia represents the most common deformation of locomotor system in children. Developmental modulation of the hip is expressed during first year of life which is important for early diagnosis and treatment. Therefore, in the practice, it is very important to set a diagnosis early with application of simple and convenient methods (ultrasound) in order to achieve fast and efficient therapeutical effect and avoid permanent disability. The aim of this paper is to point out the increase of prematurely born infants and their survival thanks to the development of Unit for Intensive Neonatal Care at the Pediatric Clinics in Sarajevo. Clinical investigation included 150 infants (77 girls and 73 boys) in whom the developmental hip dysplasia was diagnosed with clinical exam, ultrasound exam and x-ray of the hips. The exams were done in period of January 2012 to August 2014. Two groups of patients were formed. The first one consisted of premature infants, total number of 75 (34 girls and 41 boys), with developmental hip dysplasia that was diagnosed at the first exam at the Ultrasound unit of the Pediatric clinics and at the Intensive Neonatal Care Unit of the Pediatric Clinics in Sarajevo. Second (control) group consistsed of patients-on term infants who had diagnosed one of developmental hip dysplasia, total of 75 (43 girls and 32 boys) during first exam in the Ultrasound unit of the Pediatric clinics in Sarajevo. The frequency of premature birth is between 5 and 10% of all labors and demonstrates increasing trend. We suggest ultrasound examination of hips in each newborn, term or premature, at the age of 6 weeks after birth.

    Early auditory experiences are a prerequisite for speech and language acquisition. In healthy children, phoneme discrimination abilities improve for native and degrade for unfamiliar, socially irrelevant phoneme contrasts between 6 and 12 months of age as the brain tunes itself to, and specializes in the native spoken language. This process is known as perceptual narrowing, and has been found to predict normal native language acquisition. Prematurely born infants are known to be at an elevated risk for later language problems, but it remains unclear whether these problems relate to early perceptual narrowing. To address this question, we investigated early neurophysiological phoneme discrimination abilities and later language skills in prematurely born infants and in healthy, full-term infants. Our follow-up study shows for the first time that perceptual narrowing for non-native phoneme contrasts found in the healthy controls at 12 months was not observed in very prematurely born infants. An electric mismatch response of the brain indicated that whereas full-term infants gradually lost their ability to discriminate non-native phonemes from 6 to 12 months of age, prematurely born infants kept on this ability. Language performance tested at the age of 2 years showed a significant delay in the prematurely born group. Moreover, those infants who did not become specialized in native phonemes at the age of one year, performed worse in the communicative language test (MacArthur Communicative Development Inventories) at the age of two years. Thus, decline in sensitivity to non-native phonemes served as a predictor for further language development. Our data suggest that detrimental effects of prematurity on language skills are based on the low degree of specialization to native language early in development. Moreover, delayed or atypical perceptual narrowing was associated with slower language acquisition. The results hence suggest that language problems related to

  9. Effects of white matter injury on resting state fMRI measures in prematurely born infants.

    Directory of Open Access Journals (Sweden)

    Christopher D Smyser

    Full Text Available 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.

    Prematurely born children are at increased risk for language deficits at school age and beyond, but the neurobiological basis of these findings remains poorly understood. Thirty-one PT adolescents (600-1250g birth weight) and 36 T controls were evaluated using an fMRI passive language task and neurodevelopmental assessments including: the Wechsler Intelligence Scale for Children-III (WISC-III), the Peabody Picture Vocabulary Test-Revised (PPVT-R), the Comprehensive Test of Phonological Processing (CTOPP) and the Test of Word Reading Efficiency (TOWRE) at 16years of age. Neural activity was assessed for language processing and the data were evaluated for connectivity and correlations to cognitive outcomes. PT subjects scored significantly lower on all components of the WISC-III (p<0.05) compared to term subjects, but there was no significant difference in PPVT-R scores between the groups. Functional connectivity (fcMRI) between Wernicke's area (left BA 22) and the right supramarginal gyrus (BA 40) was increased in preterm subjects relative to term controls (p=0.03), and the strength of this connection was inversely related to performance on both the PPVT-R (R(2)=0.553, p=0.002), and the verbal comprehension index (R(2)=0.439, p=0.019). Preterm adolescents engage a dorsal right hemisphere region for language at age 16years. Those with the greatest cognitive deficits demonstrate increasing reliance on this alternate pathway.

    Successful resuscitation of prematurely born infants is dependent on achieving adequate alveolar ventilation and vasodilation of the pulmonary vascular bed. Elevation of end-tidal carbon dioxide (ETCO(2)) levels may indicate pulmonary vasodilation. This research aims to study the temporal changes in ETCO(2) levels and the infant's respiratory efforts during face mask resuscitation in the labour suite, and to determine if the infant's first inspiratory effort was associated with a rise in the ETCO(2) levels, suggesting pulmonary vasodilation had occurred. This study is an observational one. The subjects of the study are forty infants with a median gestational age of 30 weeks (range 23-34). Inflation pressures, expiratory tidal volumes and ETCO(2) levels were measured. The median expiratory tidal volume of inflations prior to the onset of the infant's respiratory efforts (passive inflations) was lower than that of the inflation associated with the first inspiratory effort (active inflation) (1.8 (range 0.1-7.3) versus 6.3 ml/kg (range 1.9-18.4), plevels (0.3 (range 0.1-2.1) versus 3.4 kPa (0.4-11.5), plevel (2.2 kPa (range 0.3-9.3)) of the two passive inflations following the first active inflation were also higher than the median expiratory tidal volume and ETCO(2) levels of the previous passive inflations (pcarbon dioxide elimination, likely due to pulmonary vasodilation, occurred with the onset of the infant's respiratory efforts.

  16. Total and carboxylated osteocalcin associate with insulin levels in young adults born with normal or very low birth weight.

    Directory of Open Access Journals (Sweden)

    Päivi M Paldánius

    Full Text Available OBJECTIVE: Osteocalcin (OC, a bone-derived protein, has been implicated in the regulation of glucose and energy metabolism. Young adults born with very low birth weight (VLBW have altered glucose regulation and lower bone mineral density (BMD compared with those born at term. The aim of this study was to explore the association between bone and glucose metabolism in healthy young adults born prematurely or at term. METHODS: The cohort of this cross-sectional study comprised 332 non-diabetic young adults (age 18 to 27 years born either preterm with VLBW (n = 163 or at term (n = 169. OC, carboxylated osteocalcin (cOC and markers of glucose metabolism were measured at fasting and after a 75-g oral glucose tolerance test (OGTT. RESULTS: VLBW adults were shorter, had lower BMD (p<0.001 and higher fasting OC (p = 0.027 and cOC (p = 0.005 than term-born subjects. They also had higher 2-hour insulin (p = 0.001 and glucose (p = 0.037 concentrations. OGTT induced a significant reduction in OC (p<0.001, similar in both groups. OC reduction was not associated with OGTT-induced increases in insulin (p = 0.54. However, fasting total OC and cOC correlated negatively with fasting insulin after adjustment for age, gender, BMD and VLBW status (r = -0.182, p = 0.009 and r = -0.283, p<0.001, respectively. CONCLUSION: Adults born with VLBW have higher OC and cOC than their peers born at term. This may in part reflect the mechanisms that underlie their lower BMD and decreased insulin sensitivity. Serum OC appears to be negatively associated with long-term glucose regulation whereas acute changes during OGTT may be mediated via other mechanisms.

    Full Text Available Abstract Background Being born with low birth weight may have an impact on different aspects of mental health, psychosocial functioning and well-being; however results from studies in young adulthood have so far yielded mixed findings. The aim of this study was to assess the long-term impact in young adulthood on self-reported mental health, health-related quality of life, self-esteem and social relations by investigating differences between two low birth weight groups and a control group. Methods In a follow-up at 20 years of age, 43 preterm VLBW (birth weight ≤ 1500 g, 55 term SGA (birth weight  Results The VLBW and SGA groups reported significantly more mental health problems than controls. The VLBW group predominantly had internalizing problems, and the non-significant association with ASR Total score was reduced by the Intelligence Quotient (IQ. The SGA group had increased scores on both internalizing and externalizing problems, and the association with ASR Total score remained significant after adjusting for IQ in this group. Both low birth weight groups reported less interaction with friends and lower quality of life related to mental health domains than controls. Self-esteem scores were lower than in the control group for athletic competence (VLBW and social acceptance (SGA. Conclusion Our findings suggest that self-reported mental health and well-being in young adulthood may be adversely affected by low birth weight, irrespective of whether this is the result of premature birth or being born SGA at term.

    INTRODUCTION: Preterm birth is associated with increased risk of asthma-like symptoms and purchase of prescription asthma medication in childhood. We investigated whether this association persists into adulthood and whether it is affected by accounting for neonatal respiratory morbidity (acute...... respiratory disease and bronchopulmonary dysplasia). METHODS: A national cohort of all infants born in Denmark in the period 1980-2009 was included in this register study. Data on purchase of asthma medication (combination of inhaled β-2 agonists and other drugs for obstructive airway disease) in 2010......-2011 were obtained from the Danish National Prescription Registry. Associations between gestational age (GA), neonatal respiratory morbidity and a cross-sectional evaluation of asthma medication purchase were explored by multivariate logistic regressions. RESULTS: A full dataset was obtained on 1...

    We explored whether repeated dose of antenatal betamethasone and variation in intrauterine growth of prematurely born children predict temperament characteristics at the age of 2 years. The patients (n = 142) were prematurely born children (mean gestational age: 31.0 weeks; range: 24.6-35.0 weeks) who participated in a randomized and blinded trial testing the effects of a repeated dose of antenatal betamethasone in imminent preterm birth. Fetal growth was estimated as weight, length, and head circumference in SDs according to Finnish growth charts. Parents assessed their toddlers' temperament with 201 items of the Early Childhood Temperament Questionnaire (mean child corrected age: 2.1 years). No significant main effects of repeated betamethasone on toddler temperament existed. However, a significant interaction between study group and duration of exposure to betamethasone emerged; those exposed to a repeated dose for >24 hours before delivery were more impulsive. One-SD increases in weight, length, and head circumference at birth were associated with 0.14- to 0.19-SD lower levels of negative affectivity (fearfulness, anger proneness, and sadness); 1-SD increases in length, weight, and head circumference at birth were associated with 0.14- to 0.18-SD higher levels of effortful control (self-regulation). Repeated antenatal betamethasone did not induce alterations in toddler temperament. The results, however, suggest that a longer duration of exposure is associated with higher impulsivity scores. Regardless of betamethasone exposure, slower fetal growth exerted influences on temperament. Our findings indicate prenatal programming of psychological development and imply that more attention is needed to support the development of infants born at the lower end of the fetal growth distribution.

    2010-01-01

    Full Text Available Little is known about motor development in late preterm born infants. Our objective was to determine long-term outcome of motor skills of infants born between 32 and 34 weeks. All infants were assessed at corrected ages of 3 and 9 months, using the Alberta Infant Motor Scale. At corrected ages of 4 years, the Movement Assessment Battery for Children was done. Seventy infants were seen at 4 years of age (median of 3 assessments per infant. Abnormal assessment at 3 or 9 months of age resulted in normal outcome in almost 80% at 4 years. On the other hand, a normal outcome in the first year of life resulted in an abnormal outcome at 4 years in 10% of the infants. Our results suggest that long-term followup of these late preterm born infants is necessary, as the assessments in the first year do not predict the long-term outcome.

    Full Text Available Introduction. Intraventricular hemorrhage occurs in almost one fifth of prematurely born children. Due to present complications, such as hydrocephalus and neurological deficit, it endangers the child’s life, therefore there is the need for understanding and prevent risk factors as well as the need for finding most optimal methods of treatment. Objective. The aim of the study was to point out the current therapeutic modalities of the treatment of posthemorrhagic hydrocephalus in prematurely born children. Methods. The study included 60 patients divided into two groups of 30 patients treated at the University Children’s Hospital of Belgrade in the period 2003-2008. Results. Treatment outcome of the control group of patients treated by standard methods was influenced by gestational age (p=0.024, head circumference on birth (p=0.043, body mass on birth (p=0.006, Apgar score on birth (p<0.001, peripartum asphyxia (p<0.001, cardiorespiratory arrest (p<0.001, respiratory distress (p=0.002 and intraventricular hemorrhagic grade (p<0.001. As statistically significant predictors of the poor treatment outcome of the experimental group of patients treated by using Ommaya reservoir were identified: low body mass on birth (p<0.05, low Apgar score (p<0.05, prolonged number of days on assisted ventilation (p<0.05, presence of peripartum asphyxia (p<0.05 and cardiorespiratory arrest (p<0.05. Conclusion. No statistically significant difference was detected in the outcome between the patients treated by the standard method and those with installed Ommaya reservoir. However, the difference of 10% in mortality between the two groups may be clinically significant so that further studies of larger samples are necessary.

    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. 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. Preterm children reading, and parent-ratings of child function. Multiple regression models evaluated contributions to EF skills and functional outcomes. 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. 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. Copyright © 2011 Elsevier Ltd.

    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 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.

    IS KNOWN ALREADY: Children born after ART have more adverse perinatal outcomes, i.e. preterm births, low birthweights and birth defects. Previous studies have shown divergent results regarding the risk of cancer among children born after ART. STUDY DESIGN, SIZE, DURATION: A retrospective Nordic population......STUDY QUESTION: Do children and young adults born after assisted reproductive technology (ART) have an increased risk of cancer? SUMMARY ANSWER: Children born after ART showed no overall increase in the rate of cancer when compared with children born as a result of spontaneous conception. WHAT...... children born after spontaneous conception (1.8/1000 children, 18.8/100 000 person-years). Leukaemia was the most common type of cancer (n = 278, 0.62/1000 children) but no significantly increased incidence was found among children born after ART. An increased risk was observed for 2 of 12 cancer groups...

    Full Text Available Subjects born preterm have an increased risk for age-associated diseases, such as cardiovascular disease in later life, but the underlying causes are largely unknown. Shorter leukocyte telomere length (LTL, a marker of biological age, is associated with increased risk of cardiovascular disease.To compare LTL between subjects born preterm and at term and to assess if LTL is associated with other putative cardiovascular risk factors at young adult age.We measured mean LTL in 470 young adults. LTL was measured using a quantitative PCR assay and expressed as T/S ratio. We analyzed the influence of gestational age on LTL and compared LTL between subjects born preterm (n = 186 and at term (n = 284. Additionally, we analyzed the correlation between LTL and potential risk factors of cardiovascular disease.Gestational age was positively associated with LTL (r = 0.11, p = 0.02. Subjects born preterm had shorter LTL (mean (SD T/S ratio = 3.12 (0.44 than subjects born at term (mean (SD T/S ratio = 3.25 (0.46, p = 0.003. The difference remained significant after adjustment for gender and size at birth (p = 0.001. There was no association of LTL with any one of the putative risk factors analyzed.Young adults born preterm have shorter LTL than young adults born at term. Although we found no correlation between LTL and risk for CVD at this young adult age, this biological ageing indicator may contribute to CVD and other adult onset diseases at a later age in those born preterm.

    To examine the efficacy of COPE on maternal and child anxiety associated with younger mothers of premature infants. The COPE program provides instruction and practice in parenting behaviors specific to the NICU, in combination with information that reduces ambiguity about their infant's appearance and behaviors. Secondary data analysis was conducted on data obtained from a larger randomized controlled trial with 253 mothers of low birthweight premature infants to examine the efficacy of the Creating Opportunities for Parent Empowerment (COPE) program, an educational-behavioral parent intervention in the NICU, on maternal and child anxiety based on maternal age. For these analyses, child and maternal anxiety were assessed using the Child Behavior Checklist for Ages 2 to 3 and the State-Trait Anxiety Inventory collected at 24 months and 2 to 4 days postintervention, respectively. To test study hypotheses, we conducted multiple regression models using the structural equation modeling approach to path analysis. Multiple regression results for the full model indicated that there was a significant COPE × mothers' age interaction effect on both mothers' anxiety and child anxiety. Participation in the COPE program significantly predicted lower levels of mothers' anxiety at postintervention as well as lower levels of child anxiety at 24 months for younger mothers (18-21 years old), but not for mothers over 21 years old. Participating in COPE was associated with more favorable mental health outcomes for younger mothers and their children than mothers over 21 years old. Participation in the COPE program may help close the health disparities gap by improving behaviors in infants of younger mothers to rates similar to those of children of mothers over 21 years old.

    Background Previous studies have demonstrated that indomethacin lowers the incidence and decreases the severity of intraventricular hemorrhage, as well as improves the cognitive outcome, in prematurely born male infants. Objective The purpose of this work was to use functional magnetic resonance imaging to test the hypothesis that neonatal indomethacin treatment would differentially affect brain activation across genders in school-aged, prematurely born children during performance of a language task. Methods Forty-seven prematurely born children (600–1250-g birth weight) and 24 matched term control subjects were evaluated using a functional magnetic resonance imaging passive language task and neurodevelopmental assessments that included the Wechsler Intelligence Scale for Children-III and the Peabody Picture Vocabulary Test-Revised. Neural activity was assessed during both phonologic and semantic processing in the functional magnetic resonance imaging protocol. Results Neurodevelopmental assessments demonstrated significant differences in full-scale, verbal, and performance intelligence quotient, as well as Peabody Picture Vocabulary Test scores, between the preterm and term control subjects. Rates of perinatal complications did not differ significantly across preterm treatment groups, but male preterm subjects randomly assigned to saline tended to have lower Peabody Picture Vocabulary Test-Revised scores than did all of the other preterm groups. During phonological processing, a significant treatment-by-gender effect was demonstrated in 3 brain regions: the left inferior parietal lobule, the left inferior frontal gyrus (Broca's area), and the right dorsolateral prefrontal cortex. Conclusions These data demonstrate a differential effect of indomethacin administration early in postnatal life on the subsequent development of neural systems that subserve language functioning in these male and female preterm infants.

    To study whether antenatal or neonatal glucocorticoid therapy to reduce the incidence and severity of chronic lung disease in preterm infants is associated with long-term adverse cardiac effects and hypertension. Retrospective matched-cohort study. Outpatient clinic of a tertiary care hospital. One hundred ninety-three children aged 7 to 10 years who had been born prematurely between December 2, 1993, and September 15, 1997. Main Exposure Neonatal treatment with dexamethasone disodium phosphate(n = 48) or the clinically equally effective glucocorticoid hydrocortisone (n = 51), or only antenatal treatment with betamethasone disodium phosphate and betamethasone acetate (n = 51). These 3 groups were compared with a reference group of prematurely born children who had not been exposed to perinatal glucocorticoid therapy (n = 43). General hemodynamic data (heart rate and blood pressure), cardiovascular function as assessed at echocardiography, intima-media thickness of the carotid arteries, and cardiac biochemical features as early markers of expansion and volume overload of the cardiac left ventricle (B-type natriuretic peptide and N-terminal pro-B-type natriuretic peptide). No significant group differences were found for heart rate, blood pressure, biochemical features, intima-media thickness, or systolic or diastolic left ventricular function. Although no differences were found in blood pressure and cardiovascular function at school age in children antenatally or neonatally treated with glucocorticoids, further cardiovascular follow-up may be advisable because cardiovascular dysfunction may become apparent only later in life.

    Full Text Available Background: Dyslipidemia is a marker for ischemic heart disease (IHD, which can be detected in early childhood and tracks to adulthood. Dyslipidemia, along with factors like diet, obesity and sedentary activity, increases the risk of a child developing IHD in adulthood. Early detection and modification of these risk factors can prevent IHD. Objectives: To study the lipid profile in children born to parents with history of premature IHD and also to study the effect of diet, lifestyle factors, and obesity in the study group. Materials and Methods: Fifty children of parents with premature IHD and 50 control children without any family history of IHD were analyzed for cardiovascular risk factors such as lipid profile, body mass index (BMI and hypertension. The effects of modifiable risk factors like diet and physical activity on lipid profile were analyzed. The correlation between parent and child lipid profile was studied. Results: Mean total cholesterol, low density lipoprotein cholesterol and triglycerides were significantly higher (P<0.05 in children with family history of IHD as compared to children without family history. There was a positive correlation between lipid levels of parents and their children. Children with elevated BMI, a sedentary lifestyle, and excess oily/junk diet intake showed increased incidence of dyslipidemia (P<0.05. Conclusions: Children of IHD patients have significant incidence of dyslipidemia. The risk factors like BMI, diet and physical activity increase the incidence of dyslipidemia. Therefore, all children of premature IHD patients should be screened for dyslipidemia.

    A cross-sectional study examined adults aged 21 to 35 years who underwent left cardiac catheterization in the Cardiovascular Center for Puerto Rico and the Caribbean during 2008-2012 due to myocardial infarction. Demographic characteristics, clinical risk factors, and the extent of CAD were documented. Chi-square statistic or Fisher's exact test was used to compare the distribution of demographic, clinical, and lifestyle characteristics across CAD extent. Polytomous logistic regression models were fitted to estimate the prevalence odds ratios (POR) with 95% confidence intervals (Cl) for non-obstructive and obstructive coronary disease (OCD) compared with normal coronary anatomy. Statistical analyses were performed using Stata 11.0. Sixty-three (n = 63) adults were evaluated (81% were men). The mean age was 31 ± 4 years. The most frequent clinical risk factors were history of tobacco use, hyper tension, and dyslipidemia. Obesity was present in 45.9% of subjects and OCD was present in 52.38% of subjects. Obesity and family history of CAD were significantly associated with OCD when adjusted by age. Obese patients had 5.94 times the possibility of having OCD than normal weight patients. Obesity was the most important treatable predictor of premature obstructive CAD in our young adult population.

    This study examined the effects of prematurity, cumulative medical risk, and proximal and distal social forces on individual differences in the activity of the hypothalamic-pituitary-adrenal (HPA) axis in young adulthood. A prospective sample of 149 infants born healthy preterm (PT; n = 22), sick PT ( n = 93, medical illness, neurological illness, small for gestational age), and full term ( n = 34) was recruited from a Level III neonatal intensive care unit in southern New England between 1985 and 1989 and followed to age 23 years. Cumulative medical risk was indexed across seven assessment waves (spanning 17 years) using medical and neurological health status at birth, toddlerhood (ages 18 and 30 months), childhood (ages 4 and 8 years), and adolescence (ages 12 and 17 years). Distal risk included socioeconomic status (SES) at birth. Proximal social factors were indexed from assessments of the home environment and measures of child vulnerability and maternal self-esteem, involvement, and control style from birth, 4 years, 8 years, and 12 years. At age 23 years, five saliva samples were collected upon awakening, 45 min after waking, 4 hr after waking, 8 hr after waking, and bedtime (later assayed for cortisol). Results reveal effects of cumulative medical risk on the diurnal pattern of HPA axis activity, with moderating effects of SES and proximal social factors. Findings are discussed in terms of implications for contemporary theories related to developmental sensitivity and susceptibility to context and the developmental origins of health and disease theory.

    Adolescents born preterm (PT) with no evidence of neonatal brain injury are at risk of deficits in visual memory and fine motor skills that diminish academic performance. The association between these deficits and white matter microstructure is relatively unexplored. We studied 190 PTs with no brain injury and 92 term controls at age 16 years. The Rey-Osterrieth Complex Figure Test (ROCF), the Beery visual-motor integration (VMI), and the Grooved Pegboard Test (GPT) were collected for all participants, while a subset (40 PTs and 40 terms) underwent diffusion-weighted magnetic resonance imaging. PTs performed more poorly than terms on ROCF, VMI, and GPT (all P VMI (all P VMI and left middle cerebellar peduncle FA. Novel strategies to target fine motor skills and the cerebellum may help PTs reach their full academic potential. © The Author 2017. Published by Oxford University Press.

    It is unclear what the predictive value of very early development of gestures and language is on later language ability in prematurely born very-low-birth-weight (VLBW; birth weight ≤1500g) children. The aim of the present study was to analyse the predictive value of early gestures and a receptive lexicon measured between the ages of 0;9 and 1;3, as well as the predictive value of receptive and expressive language ability at 2;0 for language skills at 5;0 in VLBW children. The subjects were 29 VLBW children and 28 full-term children whose language development has been followed intensively between the ages of 0;9 and 2;0 using the Finnish version of the MacArthur Developmental Inventory and the Reynell Developmental Language Scales (RDLS III). At 5;0, five selected verbal subtests of the Nepsy II test and the Boston Naming Test (BNT) were used to assess children's language skills. For the first time in VLBW children, the development of gestures measured between the ages of 0;9 and 1;3 was shown to correlate significantly and positively with language skills at 5;0. In addition, both receptive and expressive language ability measured at 2;0 correlated significantly and positively with later language skills in both groups. Moreover, according to the hierarchical regression analysis, the receptive language score of the RDLS III at 2;0 was a clear and significant predictor for language skills at 5;0 in both groups. The findings particularly underline the role of early receptive language as a significant predictor for later language ability in VLBW children. The results provide evidence for a continuity between early language development and later language skills. After reading this article, readers will understand the associations between the very early (≤2 years of age) development of gestures and language (i.e. early receptive lexicon, expressive lexicon at 2;0, receptive and expressive language ability at 2;0) and the language skills at 5;0 in prematurely born

    ,5% 2-5 consultas y 27,1% refieren 6 o más, 16,2% de las madres presentaron Dolencia Hipertensiva del Estado Gestacional (DHEG, y 51,3% tuvieran parto normal. Se concluye que la prematuridad fué elevada, representando importante causa de la morbimortalidad neonatal, como también acarretar complicaciones clínicas y obstétricas para la madre. La DHEG aún representa um risco para la gestación. És necesário que nuevos estúdios sobre la temática sean realizados para se conocer la verdadera magnitud del problema.This is a descriptive study that took place in a public maternity in Fortaleza Ce, with objective to characterize the prematureness among newly born (RN interned in the Unidade Neonatal due to the premature amniorrexe. It was analyzed 37 newborns along with their mothers. From the newborns it was analyzed: prematureness degree, Apgar and reanimation need; and from their mothers: gestational age, pre natal care, birth and gestational pathologies. It was found that 35,1% of the babies are premature and 29,7% had a 0-6 Agar during the first minute of life, needing reanimation. As for the gestational age, 35,1% presented membrane ruptures before the 37th week of birth, 5,4% did not go through pre natal care, 67,5% attended from 2 to 5 appointments and 27,1% attended to 6 or more, 16,2% of the mothers presented Gestational Specific Highblood Pressure Disease (GSHPD and 51,3% of the mothers went through normal delivery. It was concluded that the prematureness was high, being a main cause of newborn morbid/mortality and that it also brings clinical and obstetric complications for the mothers. The GSHPD still represents a risk to pregnancy. More studies on the subject are needed in order to acknowledged the real magnitude of the problem.

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

    Children born with very low birth weight (VLBW) are at risk for neurocognitive and behavioral sequelae. Although VLBW infants are at higher risk for deficits in executive functions (EFs) and social functioning during school-age years, few studies have investigated those sequelae or their association in young children born VLBW. We examined the associations between EFs and social functioning in preterm, VLBW children age 4-6 years (n = 20) and matched, term-born, normal birth weight controls admitted to the neonatal intensive care unit (NICU) after birth (n = 18). The groups did not differ significantly on measures of EFs, social information processing, or parent-reported social adjustment. The VLBW group had lower IQs than controls, though both group means were in the average range. Within the VLBW group, medical predictors of better EFs included older gestational age at birth and no history of bronchopulmonary dysplasia. Across groups, EFs and social information processing were positively correlated. Deficits in EFs and social functioning may emerge after the preschool years in VLBW children, or improved care of children born VLBW may be reducing the cognitive and psychosocial sequelae observed in earlier cohorts. Among children born VLBW, early EFs may be directly related to social information processing.

    Primary adrenal insufficiency (Addison's disease) is a rare autoimmune disease. Until recently, life expectancy in Addison's disease patients was considered normal. To determine the mortality rate in Addison's disease patients. i) Patients registered with Addison's disease in Norway during 1943-2005 were identified through search in hospital diagnosis registries. Scrutiny of the medical records provided diagnostic accuracy and age at diagnosis. ii) The patients who had died were identified from the National Directory of Residents. iii) Background mortality data were obtained from Statistics Norway, and standard mortality rate (SMR) calculated. iv) Death diagnoses were obtained from the Norwegian Death Cause Registry. Totally 811 patients with Addison's disease were identified, of whom 147 were deceased. Overall SMR was 1.15 (95% confidence intervals (CI) 0.96-1.35), similar in females (1.18 (0.92-1.44)) and males (1.10 (0.80-1.39)). Patients diagnosed before the age of 40 had significantly elevated SMR at 1.50 (95% CI 1.09-2.01), most pronounced in males (2.03 (1.19-2.86)). Acute adrenal failure was a major cause of death; infection and sudden death were more common than in the general population. The mean ages at death for females (75.7 years) and males (64.8 years) were 3.2 and 11.2 years less than the estimated life expectancy. Addison's disease is still a potentially lethal condition, with excess mortality in acute adrenal failure, infection, and sudden death in patients diagnosed at young age. Otherwise, the prognosis is excellent for patients with Addison's disease.

    Background West Nile virus (WNV) infection is associated with acute morbidity and mortality in adults and children. Information on the effects of maternal WNV illness during pregnancy on early childhood development is limited. This study was designed to examine the relationship between maternal WNV illness during pregnancy and birth and developmental outcomes at age 3 years. Methods Mother-child participants were identified using a national surveillance registry for women with WNV illness during pregnancy. Maternal and infant health data and relevant family characteristics were obtained through medical record reviews and maternal questionnaires. All infants received ophthalmologic examinations. Child development was evaluated at age 3 years using the Bayley Scales of Infant and Toddler Development–Third Edition (Bayley-III). Results As a group, the children’s (N = 11) birth weight, head circumference, and infant ophthalmologic examination results were within age expectations; one child was born preterm (gestational age 36 weeks). Mean (SD) age at the time of Bayley-III testing was 36.7 (3.8) months. The group’s mean performance on the Bayley-III was at or above age level in all domains, but one child showed a mild delay in the Adaptive domain. The variability observed in this sample (1/53 [1.9%] Domain scores < −2.0 SDs) was consistent with expectations based upon the distribution of Bayley-III Domain scores in the general population. Conclusion Maternal WNV infection does not appear to be associated with global developmental delays in young children. These results are preliminary, however, and require confirmation in future research. PMID:25196266

    Nina Kaseva

    Full Text Available BACKGROUND: Adults born preterm at very low birth weight (VLBW, <1500 g have elevated levels of risk factors for cardiovascular diseases and type 2 diabetes. Preliminary observations suggest that this could partly be explained by lower rates of physical activity. The aim of this study was to assess physical activity in healthy young adults born preterm at very low birth weight compared with term-born controls. METHODOLOGY/PRINCIPAL FINDINGS: We studied 94 unimpaired young adults, aged 21-29 years, born at VLBW and 101 age-, sex-, and birth hospital-matched term-born controls from one regional center in Southern Finland. The participants completed a validated 30-item 12-month physical activity questionnaire and the NEO-Personality Inventory based on the Big Five taxonomy, the most commonly used classification of personality traits. Yearly frequency, total time, total volume and energy expenditure of conditioning and non-conditioning leisure-time physical activity (LTPA and commuting physical activity were compared between VLBW and term-born subjects. A subset of participants underwent dual-energy x-ray absorptiometry for body composition measurement. Data were analyzed by multiple linear regression. Compared with controls, VLBW participants had lower frequency [-38.5% (95% CI; -58.9, -7.7], total time [-47.4% (95% CI; -71.2, -4.1], total volume [-44.3% (95% CI; -65.8, -9.2] and energy expenditure [-55.9% (95% CI; -78.6, -9.4] of conditioning LTPA when adjusted for age, sex, body mass index, smoking, parental education and personality traits. Adjusting for lean body mass instead of body mass index attenuated the difference. There were no differences in non-conditioning LTPA or commuting physical activity. CONCLUSIONS/SIGNIFICANCE: Compared with term-born controls, unimpaired VLBW adults undertake less frequent LTPA with lower total time and volume of exercise resulting in lower energy expenditure. Differences in personality that exist between the

    Early life stress, such as painful and stressful procedures during neonatal intensive care after preterm birth, can permanently affect physiological, hormonal and neurobiological systems. This may contribute to altered programming of the hypothalamic-pituitary-adrenal axis (HPAA) and provoke changes in HPAA function with long-term health impacts. Previous studies suggest a lower HPAA response to stress in young adults born preterm compared with controls born at term. We assessed whether these differences in HPAA stress responsiveness are reflected in everyday life HPAA functioning, i.e. in diurnal salivary cortisol patterns, and reactivity to a low-dose dexamethasone suppression test (DST), in unimpaired young adults born preterm at very low birth weight (VLBW; <1500 g). The participants were recruited from the Helsinki Study of Very Low Birth Weight Adults cohort study. At mean age 23.3 years (2.1 SD), 49 VLBW and 36 controls born at term participated in the study. For cortisol analyzes, saliva samples were collected on two consecutive days at 0, 15, 30 and 60 min after wake-up, at 12:00 h, 17:00 h and 22:00 h. After the last salivary sample of the first study day the participants were instructed to take a 0.5 mg dexamethasone tablet. With mixed-effects model no difference was seen in overall diurnal salivary cortisol between VLBW and control groups [13.9% (95% CI: -11.6, 47.0), P = 0.31]. Salivary cortisol increased similarly after awakening in both VLBW and control participants [mean difference -2.9% (29.2, 33.0), P = 0.85]. Also reactivity to the low-dose DST (awakening cortisol ratio day2/day1) was similar between VLBW and control groups [-1.1% (-53.5, 103.8), P = 0.97)]. Diurnal cortisol patterns and reactivity to a low-dose DST in young adulthood were not associated with preterm birth.

    Full Text Available A sample of 51 children aged 7 with a history of prematurity was compared to 44 age-matched children who were born at term at the HCPA. The premature children had had gestational ages up to 37 weeks and 6 days and were born weighing less than 2500g. The control group consisted of children born with gestational age between 38 and 42 weeks and weights above 2S00g. The evaluation criteria were clinical examination, neurological examination and the evolutional neurological evaluation (ENE. The results pointed out that impulsiveness, aggressiveness, disorganization and enuresis were prevalent symptoms of developmental disturbances in the sample of prematures. Alterations at neurological examination did not discriminate between the two groups, although cerebral palsy occurred only in the proup of prematures. The ENE functions which differentiated the two groups studied were dynamic balance, appendicular and trunk-limb coordination and motor persistence.Para estudar o desenvolvimento neuropsicomotor em amostra de prematuros aos 7 anos de idade, foram avaliadas 51 crianças prematuras e comparadas com 44 a termo.

    Autonomic functioning is altered in infants born at extremely low birth weight (ELBW; 2500 g). HF in the smallest-born ELBW participants was significantly lower than in NBW controls. In both groups, greater birth weight was associated with higher HF. Among ELBW survivors, lower birth weight predicted faster heart rate and higher DBP, but neither heart rate nor DBP appeared to be well-coordinated with baroreflex activity (LF), the principal mechanism for short-term blood pressure regulation.

    Full Text Available Intrauterine growth restriction (IUGR can lead to infants being born small for gestational age (SGA. SGA is associated with differences in brain anatomy and impaired cognition. We investigated learning and memory in children born SGA using neuropsychological testing and functional Magnetic Resonance Imaging (fMRI.18 children born appropriate for gestational age (AGA and 34 SGA born children (18 with and 16 without postnatal catch-up growth participated in this study. All children were between 4 and 7 years old. Cognitive functioning was assessed by IQ and memory testing (Digit/Word Span and Location Learning. A newly developed fMRI picture encoding task was completed by all children in order to assess brain regions involved in memory processes.Neuropsychological testing demonstrated that SGA children had IQ's within the normal range but lower than in AGA and poorer performances across measures of memory. Using fMRI, we observed memory related activity in posterior parahippocampal gyrus as well as the hippocampus proper. Additionally, activation was seen bilaterally in the prefrontal gyrus. Children born SGA showed less activation in the left parahippocampal region compared to AGA.This is the first fMRI study demonstrating different brain activation patterns in 4-7 year old children born SGA, suggesting that intrauterine growth restriction continues to affect neural functioning in children later-on.

  3. Global and regional differences in brain anatomy of young children born small for gestational age.

    Directory of Open Access Journals (Sweden)

    Henrica M A De Bie

    Full Text Available In children who are born small for gestational age (SGA, an adverse intrauterine environment has led to underdevelopment of both the body and the brain. The delay in body growth is (partially restored during the first two years in a majority of these children. In addition to a negative influence on these physical parameters, decreased levels of intelligence and cognitive impairments have been described in children born SGA. In this study, we used magnetic resonance imaging to examine brain anatomy in 4- to 7-year-old SGA children with and without complete bodily catch-up growth and compared them to healthy children born appropriate for gestational age. Our findings demonstrate that these children strongly differ on brain organisation when compared with healthy controls relating to both global and regional anatomical differences. Children born SGA displayed reduced cerebral and cerebellar grey and white matter volumes, smaller volumes of subcortical structures and reduced cortical surface area. Regional differences in prefrontal cortical thickness suggest a different development of the cerebral cortex. SGA children with bodily catch-up growth constitute an intermediate between those children without catch-up growth and healthy controls. Therefore, bodily catch-up growth in children born SGA does not implicate full catch-up growth of the brain.

    BACKGROUND: The risk of cerebral palsy, the commonest physical disability of children in western Europe, is higher in infants of very low birthweight (VLBW)--those born weighing less than 1500 g--and those from multiple pregnancies than in infants of normal birthweight. An increasing proportion...... of Cerebral Palsy in Europe, agreed a standard definition of cerebral palsy and inclusion and exclusion criteria. Data for children with cerebral palsy born in the years 1980-96 were pooled. The data were analysed to describe the distribution and prevalence of cerebral palsy in VLBW infants. Prevalence trends...... were expressed as both per 1000 livebirths and per 1000 neonatal survivors. FINDINGS: There were 1575 VLBW infants born with cerebral palsy; 414 (26%) were of birthweight less than 1000 g and 317 (20%) were from multiple pregnancies. 1426 (94%) had spastic cerebral palsy, which was unilateral...

  6. A predictive model for respiratory syncytial virus (RSV hospitalisation of premature infants born at 33–35 weeks of gestational age, based on data from the Spanish FLIP study

    2008-12-01

    Full Text Available Abstract Background The aim of this study, conducted in Europe, was to develop a validated risk factor based model to predict RSV-related hospitalisation in premature infants born 33–35 weeks' gestational age (GA. Methods The predictive model was developed using risk factors captured in the Spanish FLIP dataset, a case-control study of 183 premature infants born between 33–35 weeks' GA who were hospitalised with RSV, and 371 age-matched controls. The model was validated internally by 100-fold bootstrapping. Discriminant function analysis was used to analyse combinations of risk factors to predict RSV hospitalisation. Successive models were chosen that had the highest probability for discriminating between hospitalised and non-hospitalised infants. Receiver operating characteristic (ROC curves were plotted. Results An initial 15 variable model was produced with a discriminant function of 72% and an area under the ROC curve of 0.795. A step-wise reduction exercise, alongside recalculations of some variables, produced a final model consisting of 7 variables: birth ± 10 weeks of start of season, birth weight, breast feeding for ≤ 2 months, siblings ≥ 2 years, family members with atopy, family members with wheeze, and gender. The discrimination of this model was 71% and the area under the ROC curve was 0.791. At the 0.75 sensitivity intercept, the false positive fraction was 0.33. The 100-fold bootstrapping resulted in a mean discriminant function of 72% (standard deviation: 2.18 and a median area under the ROC curve of 0.785 (range: 0.768–0.790, indicating a good internal validation. The calculated NNT for intervention to treat all at risk patients with a 75% level of protection was 11.7 (95% confidence interval: 9.5–13.6. Conclusion A robust model based on seven risk factors was developed, which is able to predict which premature infants born between 33–35 weeks' GA are at highest risk of hospitalisation from RSV. The model could be

    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 Pneonatal 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.

As young adults, a subset of ELBW survivors free of major neurosensory impairments provided self-reports of personality characteristics related to psychopathology. Data from 66 participants indicated that, as predicted, the association between ELBW and externalizing behaviors was moderated by fluid intelligence. Specifically, ELBW individuals with poor fluid intelligence who were born small for gestational age (birth weight intelligence might be a cognitive mechanism contributing to the development of psychopathology among nonimpaired individuals who were born at ELBW and small for gestational age.

  12. Development of a portable premature born infant's incubator using phase change material (PCM) as thermal energy storage and temperature control

    1999-12-16

    In response to the need of premature infant's incubators in many unelectrified and remote rural areas, a portable prototype of incubator heated by some melted phase change material (PCM) as thermal energy storage and temperature control has been developed. To avoid the use of electricity at all, the incubator was designed so that the air circulation can take place by natural convection. A numerical simulation on the design prototype was carried out prior to prototype production. Three identical incubator prototypes were made and tested in the laboratory and in the hospital. The obtained results so far were satisfactory. Actually, the field test was only done in a hospital to get some comments for further improvements. In near future, some other prototypes will be actually manufactured based on the already received comments. These prototypes will be donated to several hospitals and village health centers and their operation will be monitored. (author)

    Background Rhinovirus (RV) has been linked to the pathogenesis of asthma. Prematurity is a risk factor for severe RV infection in early life, but is unknown if RV elicits enhanced pro-asthmatic airway cytokine responses in premature infants. This study investigated if young children born severely premature (<32 weeks gestation) exhibit airway secretion of Th2 and Th17 cytokines during natural RV infections and if RV-induced Th2-Th17 responses are linked to more respiratory morbidity in premature children during the first two years of life. Methods We measured Th2 and Th17 nasal airway cytokines in a retrospective cohort of young children aged 0–2 years with PCR-confirmed RV infection or non-detectable virus. Protein levels of IL-4, IL-13, TSLP and IL-17 were determined with multiplex immunoassays. Demographic and clinical variables were obtained by electronic medical record (EMR) review. Results The study comprised 214 children born full term (n=108), pre-term (n=44) or severely premature (n=62). Natural RV infection in severely premature children was associated with elevated airway secretion of Th2 (IL-4 and IL-13) and Th17 (IL-17) cytokines, particularly in subjects with history of bronchopulmonary dysplasia. Severely premature children with high RV-induced airway IL-4 had recurrent respiratory hospitalizations (median 3.65 hosp/year; IQR 2.8–4.8) and were more likely to have at least one pediatric intensive care unit admission during the first two years of life (OR 8.72; 95% CI 1.3–58.7; p=0.02). Conclusions Severely premature children have increased airway secretion of Th2 and Th17 cytokines during RV infections, which is associated with more respiratory morbidity in the first two years of life PMID:25640734

    Full Text Available Objective: Depressed coronary artery disease (CAD patients may experience a poorer prognosis than non-depressed patients. The aim of this study was to find the associated factors for depressive symptoms in young adults with CAD.Method: This was a cross-sectional study within Tehran Heart Center's Premature Coronary Atherosclerosis Cohort (THC-PAC study. Young adult CAD patients (men ≤ 45 year-old and women ≤ 55 year-old were visited from March 2013 to February 2014. Demographic, clinical and laboratory data were collected and all patients were asked to fill in the Beck Depression Inventory II. Informed consent was obtained from all participants. A logistic regression model was used to find multiple associated factors of depressive symptoms.Results: Seven hundred seventy patients (mean ±SD age: 45.34 ±5.75 y, men: 47.7% were visited. The point prevalence of depressive symptoms was 46.9% in women and 30.2% in men (p < 0.001. Logistic regressions model revealed that the most important associated factors for depressive symptoms in the male premature CAD patients were opium usage (OR: 2.4, 95% CI: 1.33-4.43, major adverse cardiac events (MACE (OR: 2.2, 95% CI: 1.17-3.93, initial coronary artery bypass grafting (CABG treatment (OR: 2.1, 95% CI: 1.07-4.06, positive family history for CAD (OR: 1.8, 95% CI: 1.11-3.01 and cigarette smoking (OR: 1.7, 95% CI: 0.97-2.98.

    Objective The objective of this study was to explore the potential of the Infant/Toddler Sensory Profile (ITSP) as a screening tool for autism spectrum disorders (ASD) in prematurely born children. Methods Parents of 157 children with birth weights tools subsequently underwent clinical examination including the Autism Diagnostic Observation Schedule. Results We used classification trees to answer the question whether ITSP (or some of its subscales) could be combined with the M-CHAT and/or the CSBS-DP-ITC or its subscales into an effective ASD screening tool. Using the CSBS-DP-ITC, overall score, and the Sensation Seeking subscale of the ITSP, we obtained a screening tool that was able to identify all of the ASD children in our sample (confirmed by cross-validation). The proposed screening tool is scored as follows: 1) if the overall CSBS-DP-ITC value is <45.5, then the screening is positive; 2) if the overall CSBS-DP-ITC value is ≥45.5 and the z-score of the Sensation Seeking subscale of ITSP is ≥1.54, then the screening is positive; 3) otherwise, the screening is negative. Conclusion The use of CSBS-DP-ITC in combination with the Sensation Seeking subscale of the ITSP improved the accuracy of autism screening in preterm children. PMID:28182143

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

    To determine whether there is a direct correlation between endurance capacity and cold tolerance, maximal oxygen consumption (VO2max), and cold-induced vasodilatation (CIVD), we measured these factors in 14 young female athletes born in Hokkaido, Japan's northernmost island. We determined the VO2max by a standard incremental test on a cycle ergometer and measured the oxygen consumption (VO2) by means of the Douglas-bag method. We determined the CIVD reaction by measuring the skin temperature of the left middle finger during immersion in cold water at 0°C for 20 min. The athletes showed significant positive correlations between VO2max, expressed as l/min, and CIVD as well as other peripheral cold tolerance indexes (resistance index against frostbite and CIVD index). The body weight VO2max (VO2max/kg body weight) failed to correlate significantly with either the CIVD or with other cold tolerance indexes. These results suggest that CIVD in females may depend on factors other than those determined in this study, in addition to the functional spread of the vascular beds in peripheral tissues, including striated muscle; it is known that the size and the vascular bed in this tissue are affected by exercise training and that this results in the elevation of VO2max and VO2max/kg body weight.

    Many studies show that Juvenile Idiopathic Arthritis (JIA) is associated with early subclinical signs of atherosclerosis. Chronic inflammation per se may be an important driver but other known risk factors, such as dyslipidemia, hypertension, insulin insensitivity, a physically inactive lifestyle, obesity, and tobacco smoking may also contribute substantially. We performed a systematic review of studies through the last 20 years on early signs of subclinical atherosclerosis in children and adolescents with JIA with the purpose of investigating whether possible risk factors, other than inflammation, were considered.We found 13 descriptive cross sectional studies with healthy controls, one intervention study and two studies on adults diagnosed with JIA. Only one study addressed obesity, and physical activity (PA) has only been assessed in one study on adults with JIA and only by self-reporting. This is important as studies on PA in children with JIA have shown that most patients are less physically active than their healthy peers, and as physical inactivity in several large studies of normal schoolchildren is found to be associated with increased clustering of risk factors for cardiovascular disease. It is thus possible that an inactive lifestyle in patients with JIA is an important contributor to development of the subclinical signs of atherosclerosis seen in children with JIA, and that promotion of an active lifestyle in childhood and adolescence may diminish the risk for premature atherosclerotic events in adulthood.

    Young adults born preterm at very low birth weight (VLBW, ≤1500 g) have higher levels of cardiovascular risk factors, including impaired glucose regulation, than their term-born peers. This could be mediated through altered hypothalamic-pituitary-adrenal axis (HPAA) response to stress. To compare HPAA, glucose and insulin responses provoked by psychosocial stress in VLBW subjects versus a comparison group of term-born controls. We studied 54 unimpaired young adults, aged 19-27 years, born at VLBW and a comparison group of 40 adults born at term, group-matched for age, sex and birth hospital, from one regional centre in southern Finland. The participants underwent a standardized psychosocial stress test (Trier Social Stress Test, TSST). In conjunction with TSST, we measured salivary cortisol, plasma ACTH, cortisol, glucose and insulin. Data were analysed with mixed-effects model and multiple linear regression analyses. Baseline concentrations for cortisol, ACTH, insulin and glucose were similar in VLBW and comparison groups. During TSST, analysed with mixed-effects model, overall concentrations of plasma cortisol were 17·2% lower (95% CI; 3·5 to 28·9) in the VLBW group. The VLBW group also had lower salivary (P = 0·04) and plasma cortisol (P = 0·02) responses to TSST. Insulin and glucose concentrations correlated with changes in cortisol concentrations. Accordingly, VLBW subjects had 26·5% lower increment in insulin (95% CI; 9·8-40·1). Analyses were adjusted for age, sex, body mass index, hormonal contraception, menstrual cycle phase, time of day and parental education. VLBW adults have lower HPAA responses to psychosocial stress than term-born controls. This is accompanied by a lower insulin response. © 2013 John Wiley & Sons Ltd.

    Full Text Available Introduction Fetal and preterm infant brain is especially vulnerable to hemorrhagic and ischemic damage at the end of the second and at the beginning of the third trimester. This is due to vascular, cellular and anatomic characteristics of the brain during development. In premature babies, there is a physiological instability and limited autoregulation of cerebral circulation. Hemorrhagic and ischemic damages often occur together, though pathophysiological processes leading to lesions are different. Material and methods The paper deals with a detailed analysis of 860 ultrasound brain scans of prematurely born children. The examinations were performed at the Ultrasound Department of the Institute of Child and Youth Health Care in Novi Sad. 707 vaginally born premature infants and 153 premature infants born by Cesarean section were examined. The bleeding was graded according to the Papile classification. Results and Discussion Out of 384 children with diagnosed grade I hemorrhage, 75 premature infants (19.5% were born by Cesarean section. In the group of children with grade II hemorrhage, operative deliveries account for 14.7%. From the total of 85 children with grade III hemorrhage, (intraventricular bleeding with chamber dilatation, only 6 premature infants were born by Cesarean section (7%. Intra-parenchymal bleeding was diagnosed in a very small number of premature infants; 0.32% of all diagnosed hemorrhages were grade IV hemorrhages. In this group there were no children born by Cesarean section. The increase of hemorrhage grade is accompanied by a greater rate of pelvic presentation and manual assistance by Bracht. There were 240 prematurely born children with no echosonographically diagnosed hemorrhage, 38% of all examined premature infants. From this number, 13.3% of neonates were born by Cesarean section. Conclusion In the etiology of neonatal intracranial hemorrhage, especially prematurely born ones, apart from the trauma, which plays a

    Full Text Available The objective of this study was to evaluate the prevalence of dental caries in 192 children, 96 born prematurely and 96 at full term, in a regional hospital in Brazil. Mean age at clinical examination was 40.72 months in the full-term group (G1 and 30.44 months in the premature group (G2. The children were divided in two age subgroups: 0 to 3 and 4 to 6 years. Statistical results (Student's t and Kruskal-Wallis tests showed that dmft was 0.43 for G1 and 0.01 for G2 in the 0-3 age subgroup, and 1.7 for G1 and 1.1 for G2 in the 4-6 age subgroup. Differences were significant between G1 and G2 only in the 0-3 age subgroup (p = 0.047. Caries evaluation showed that, of the 96 children in G1, 75 were caries free, while in G2, 84 did not have the disease. These differences were not significant (p = 0.088. The lower mean dmft found in the 0-3 age subgroup in G2 may be attributed to routines established by the hospital's neonatology staff, such as frequent dental visits and preventive instructions about oral habits, oral hygiene and diet. After this age, with the completion of the primary dentition, values increased and became similar between the G1 and G2 groups. Results also suggested a highly skewed distribution since most caries were found in only a small number of children.O objetivo deste estudo foi avaliar a prevalência da cárie dentária em 192 crianças, 96 nascidas prematuramente e 96 a termo, em um hospital regional no Brasil.

    Full Text Available Preterm delivery is the single most important cause of perinatal morbidity and mortality. In Chile, preterm births have increased in the past decade, although neonatal morbidity and mortality attributable to it shows a downward trend, thanks to improvements in neonatal care of premature babies, rather than the success of obstetric preventive and therapeutic strategies. This article describes clinical entities, disease processes and conditions that constitute predisposing factors of preterm birth, as well as an outline for the prevention and clinical management of women at risk of preterm birth.

    The current study examines the relationship between premature birth and the age at which caregivers first become concerned with their child's development in a sample of 84 toddlers with autism spectrum disorder (ASD). The participants were split into two groups: those born prematurely and those born full term. The results indicate that the age of caregiver first concern is significantly younger for those born prematurely than those born full term. The average age caregivers reported first becoming concerned about their child's development was around 7 months for participants born prematurely and around 13 months for participants born full term. Possible explanations for the results and their implications are discussed.

    2007-01-01

    Full Text Available 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.

    Thomas, Kevin J. A.

    2014-01-01

    This study examines how familial contexts affect poverty disparities between the children of immigrant and U.S.-born blacks, and among black and nonblack children of immigrants. Despite lower gross child poverty rates in immigrant than in U.S.-born black families, accounting for differences in family structure reveals that child poverty risks among blacks are highest in single-parent black immigrant families. In addition, within two-parent immigrant families, child poverty declines associated with increasing assimilation are greater than the respective declines in single-parent families. The heads of black immigrant households have more schooling than those of native-black households. However, increased schooling has a weaker negative association with child poverty among the former than among the latter. In terms of racial disparities among the children of immigrants, poverty rates are higher among black than nonblack children. This black disadvantage is, however, driven by the outcomes of first-generation children of African and Hispanic-black immigrants. The results also show that although children in refugee families face elevated poverty risks, these risks are higher among black than among nonblack children of refugees. In addition, the poverty-reducing impact associated with having an English-proficient household head is about three times lower among black children of immigrants than among non-Hispanic white children of immigrants.

    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.

    Premature birth is a significant cause of infant and child morbidity and mortality. In the United States, the premature birth rate, which had steadily increased during the 1990s and early 2000s, has decreased annually for four years and is now approximately 11.5%. Human viability, defined as gestational age at which the chance of survival is 50%, is currently approximately 23–24 weeks in developed countries. Infant girls, on average, have better outcomes than infant boys. A relatively uncomplicated course in the intensive care nursery for an extremely premature infant results in a discharge date close to the prenatal EDC. Despite technological advances and efforts of child health experts during the last generation, the extremely premature infant (less than 28 weeks gestation) and extremely low birth weight infant (ELBW) (premature labor improved neonatal mortality and morbidity in the late 1990s. The recognition that chronic postnatal administration of steroids to infants should be avoided may have improved outcomes in the early 2000s. Evidence from recent trials attempting to define the appropriate target for oxygen saturation in preterm infants suggests arterial oxygen saturation between 91–95% (compared to 85–89%) avoids excess mortality.

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."

    The existing literature on language outcomes in children born prematurely focuses almost exclusively on standardized test scores rather than discourse-level abilities. The authors of this study looked longitudinally at school-age language outcomes and potential moderating variables for a group of twins born prematurely versus a control group of twins born at full term, analyzing both standardized test results and language sample data from the population-based Western Reserve Reading Project (WRRP; Petrill, Deater-Deckard, Thompson, DeThorne, & Schatschneider, 2006). Fifty-seven children born prematurely, at ≤32 weeks or children born at full term and were matched for age, gender, race, and parental education. Data included discourse-level language samples and standardized test results, collected at average ages 7, 8, and 10 years. The language samples were analyzed to yield a number of semantic and syntactic measures that were consolidated via factor analysis. Regression models showed significant differences between the 2 groups for standardized test results, although the mean score for both groups fell in the normal range. For the discourse-level language measures, however, differences never reached statistical significance. Parental education was significantly associated with improved standardized test scores. These findings suggest that in the absence of frank neurological impairment, sophisticated semantic and syntactic skills may be relatively intact in the discourse-level language of children born prematurely. Implications for assessment, particularly the potential role of attention and executive function in standardized testing tasks, are reviewed.

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

    Science.gov (United States)

    Hallman, Mikko

    2012-04-01

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

  14. Hypothyroxinemia of prematurity: rite of passage or therapeutic necessity?

    Science.gov (United States)

    Beeram, M R; Wilson, D P

    2000-11-01

    Hypothyroxinemia is a common finding in premature infants, presumably resulting from an immature hypothalamic-pituitary-thyroid axis. Because dynamic studies of thyroid function in premature infants are normal and the condition resolves spontaneously, HOP has been considered physiologic rather than pathologic. Thus, thyroid hormone supplementation has been assumed to be not required in premature infants. True hypothyroidism of hypothalamic pituitary or thyroid origin, however, does occur in premature as well as in term infants and should be investigated aggressively and treated appropriately. Current studies in premature infants with hypothyroxinemia suggest the following: infants with more than 27 weeks of gestation do not appear to benefit and may, in fact, be harmed by thyroid hormone supplementation; and short-term thyroid hormone supplementation in infants born before 27 weeks of gestation may be important to diminish morbidity and to improve neurodevelopmental outcome.

    Full Text Available Infants born preterm are at greater risk than infants born at term for mortality and a variety of health and developmental problems. Complications include acute respiratory, gastrointestinal, immunologic, central nervous system, hearing, and vision problems, as well as longer-term motor, cognitive, visual, hearing, behavioral, social-emotional, health, and growth problems. The birth of a preterm infant can also bring considerable emotional and economic costs to families and have implications for public-sector services, such as health insurance, educational, and other social support systems. The greatest risk of mortality and morbidity is for those infants born at the earliest gestational ages. However, those infants born nearer to term represent the greatest number of infants born preterm and also experience more complications than infants born at term. Preterm birth is a complex cluster of problems with a set of overlapping factors of influence. Its causes may include individual-level behavioral and psychosocial factors, neighborhood characteristics, environmental exposures, medical conditions, infertility treatments, biological factors and genetics. Many of these factors occur in combination, particularly in those who are socioeconomically disadvantaged or who are members of racial and ethnic minority groups. The empirical investigation was carried out to draw correlation between preterm birth and eventuality. This paper deals with various issues related to the premature deliveries from socio-biological perspectives.

    2011-01-01

    The high rate of premature births in the United States remains a public health concern. These infants experience substantial morbidity and mortality in the newborn period, which translate into significant medical costs. In early childhood, survivors are characterized by a variety of health problems, including motor delay and/or cerebral palsy, lower IQs, behavior problems, and respiratory illness, especially asthma. Many experience difficulty with school work, lower health-related quality of life, and family stress. Emerging information in adolescence and young adulthood paints a more optimistic picture, with persistence of many problems but with better adaptation and more positive expectations by the young adults. Few opportunities for prevention have been identified; therefore, public health approaches to prematurity include assurance of delivery in a facility capable of managing neonatal complications, quality improvement to minimize interinstitutional variations, early developmental support for such infants, and attention to related family health issues.

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

    Children born extremely prematurely are at risk for a variety of problems with motion analysis, including problems with motion-defined (MD) form recognition [Downie, A. L. S., Jakobson, L. S., Frisk, V., & Ushycky, I. (2003). Periventricular brain injury, visual motion processing, and reading and spelling abilities in children who were extremely-low-birthweight. Journal of the International Neuropsychological Society, 9, 440-449]. The aims of the present study were (1) to examine the impact of retinopathy of prematurity (ROP) and mild periventricular brain injury (PVBI) on MD form processing in this population; (2) to assess relationships between MD form recognition in these children and their performance in several other areas of visual competence. To this end, a battery of visual and visuomotor tests was administered to 43, 5- and 6-year old, extremely premature children, all of whom had escaped severe PVBI. A group of full-term controls was also studied. Relative to controls, premature children displayed clear deficits in MD form recognition and these deficits were related to the presence of ROP and/or mild PVBI, rather than to a history of prematurity per se. Regression analyses revealed significant associations in premature children between MD form processing deficits and problems with visual search, stereopsis, visuoconstructive and graphomotor skills, motor development, and Performance IQ. The results suggest that assessment of sensitivity to MD forms may be useful in the early identification of preterm children at greatest risk for visual problems associated with dorsal stream dysfunction.

    Full Text Available During an anthrax outbreak at the Pollino National Park (Basilicata, Italy in 2004, diseased cattle were buried and from these anthrax-foci Bacillus anthracis endospores still diffuse to the surface resulting in local accumulations. Recent data suggest that B. anthracis multiplies in soil outside the animal-host body. This notion is supported by the frequent isolation of B. anthracis from soil lacking one or both virulence plasmids. Such strains represent an evolutionary dead end, as they are likely no longer able to successfully infect new hosts. This loss of virulence plasmids is explained most simply by postulating a soil-borne life cycle of the pathogen. To test this hypothesis we investigated possible microevolution at two natural anthrax foci from the 2004 outbreak. If valid, then genotypes of strains isolated from near the surface at these foci should be on a different evolutionary trajectory from those below residing in deeper-laying horizons close to the carcass. Thus, the genetic diversity of B. anthracis isolates was compared conducting Progressive Hierarchical Resolving Assays using Nucleic Acids (PHRANA and next generation Whole Genome Sequencing (WGS. PHRANA was not discriminatory enough to resolve the fine genetic relationships between the isolates. Conversely, WGS of nine isolates from near-surface and nine from near-carcass revealed five isolate specific SNPs, four of which were found only in different near-surface isolates. In support of our hypothesis, one surface-isolate lacked plasmid pXO1 and also harbored one of the unique SNPs. Taken together, our results suggest a limited soil-borne life cycle of B. anthracis.

As the mainstay of the new rural construction, rural young people born in 1980's should set up the right vocational values, psychologically preparing for the rural development. As a young generation, they have high potential to develop their vocational values. Micro-governance mode based on attitude change theory is a means of intervention, characterized by emphasis on public participation, taking rural people born in 1980's as the core subjects. The issues of traditional vocational values in rural area and needs of this group of young people are also analyzed. The study suggests that stakeholders co-governance can promote the modern transformation of the values, and improve the construction of new rural social value system,thus guide the sustainable development of rural economy.

  16. Cognitive and psychosocial development concerns in children born small for gestational age.

    Science.gov (United States)

    Lee, Peter A; Houk, Christopher P W

    Outcome information for infants born small for gestational age (SGA), whether term or premature, suggests poorer cognitive function compared with appropriate size for gestational age (AGA) infants. Poorer outcome is associated with smaller size for gestational age and with lack of catch-up growth after birth. Such data have been reported from early childhood to young adulthood. Diminished head circumference at birth and growth thereafter has also been associated with poor outcome. Based on available reports, the impact of SGA birth upon psychosocial development remains unclear. While it has not been shown that growth hormone (GH) therapy impacts either cognitive or psychosocial outcome, increased head circumference standard deviation scores have been shown to occur with GH therapy. These data need to be interpreted with caution since study populations do not define etiology of SGA and definitions of SGA vary. Further, generalized group data are not applicable to individuals.

    Children born with non-optimal birth characteristics - that is, are small for gestational age and/or preterm - have an increased risk for several long-term effects such as neurological sequelae and chronic disease. The purpose of this study was to examine whether twins exhibited a different outcome, compared with singletons, in terms of hospitalization during adolescence and early adulthood, and to what extent differences remain when considering the divergence in birth characteristics between singletons and twins. Persons born between 1973 and 1983 in Sweden and surviving until age 13 were included and followed until the end of 2006. Data on birth characteristics, parental socio-demographic factors, and hospitalizations were collected from national registers. Adjusting for parental socio-demographic factors, twins had a higher risk of being hospitalized than singletons (odds ratio, OR = 1.17, 95% confidence interval, CI = 1.10-1.25) and more often due to 'Congenital anomalies' (OR = 1.18, 95% CI = 1.06-1.28), 'Infections' (OR = 1.14; 95% CI = 1.08-1.20), 'External causes of illness' (OR = 1.10, 95% CI = 1.06-1.15), and 'Diseases of the nervous system' (OR = 1.18, 95% CI = 1.10-1.26). Stratifying for birth characteristics, this difference diminishes, and for some diagnoses non-optimal twins seem to do slightly better than non-optimal singletons. Thus, twins with non-optimal birth characteristics had a lower risk of hospitalization than non-optimal singletons on, for example, 'Congenital anomalies' and 'Diseases of the nervous system' (OR = 0.86, 95% CI = 0.77-0.96; OR = 0.88, 95% CI = 0.81-0.97, respectively) and Total (any) hospitalization (OR = 0.87, 95% CI = 0.83-0.92). Among those with optimal birth characteristics, twins had an increased hospitalization due to 'External causes of illness' (OR = 1.07, 95% CI = 1.02-1.13) compared with optimal singletons. Twins have higher hospitalization rates than singletons. In stratifying for birth characteristics, this

    This paper presents the whole-body specific absorption rate (WBSAR) assessment of embryos and new-born rats' exposure in a reverberating chamber (RC) operating at 2.4 GHz (WiFi). The finite difference in time domain (FDTD) method often used in bio-electromagnetism is facing very slow convergence. A new simulation-measurement hybrid approach has been proposed to characterize the incident power related to the RC and the WBSAR in rats, which are linked by the mean squared electric field strength in the working volume. Peak localized SAR in the rat under exposure is not included in the content of the study. Detailed parameters of this approach are determined by simulations. Evolutions for the physical and physiological parameters of the small rats at different ages are discussed. Simulations have been made to analyse all the variability factors contributing to the global results. WBSAR information and the variability for rats at different ages are also discussed in the paper.

    A prospective study concerning 66 prematures born after 32 weeks of gestation showed a 33% incidence of positive rolandic sharp waves (PRSW) on EEGs. The results showed a good sensitivity (Se = 95%) and specificity (Sp = 93%) of PRSW for the diagnosis of periventricular ischemia with motor sequelae. A PRSW frequency higher than one per minute and its persistence on 2 successive EEGs constitutes an indication of severity of the lesions. This study emphasizes the necessity of several EEG recordings in prematures.

  20. Premature ovarian failure.

    2010-11-01

    Premature ovarian failure (POF) is a common cause of infertility in women, and is characterised by amenorrhoea, hypo-oestrogenism and elevated gonadotrophin levels in women under the age of 40. Known causes include iatrogenic agents that cause permanent damage to the ovaries, such as chemotherapy, radiation therapy and surgery, autoimmune conditions, X-chromosome abnormalities and autosomal genetic conditions. However, few genes have been identified that can explain a substantial proportion of cases of POF. Most women with POF are deeply upset by the diagnosis, partly due to the unexpected menopausal symptoms, but also due to infertility. Therefore, early detection would provide better opportunity for early intervention, and furthermore, the identification of specific gene defects will help to direct potential targets for future treatment.

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

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

  3. Intrauterine infection and prematurity.

    Gonçalves, Luís F; Chaiworapongsa, Tinnakorn; Romero, Roberto

    2002-01-01

    Intrauterine infection is a major cause of premature labor with and without intact membranes. Intrauterine infection is present in approximately 25% of all preterm births and the earlier the gestational age at delivery, the higher the frequency of intra-amniotic infection. Microorganisms may also gain access to the fetus before delivery. A fetal inflammatory response syndrome elicited in response to microbial products is associated with the impending onset of preterm labor and also with multi-systemic organ involvement in the human fetus and a higher rate of perinatal morbidity. The most common microorganisms involved in intrauterine infections are Ureaplasma urealyticum, Fusobacterium species and Mycoplasma hominis. The role of Chlamydia trachomatis and viruses in preterm labor remain to be determined. Use of molecular microbiology techniques to diagnose intrauterine infection may uncover the role of fastidious microorganisms that have not yet been discovered. Antibiotic administration to patients with asymptomatic bacteriuria is associated with a significant reduction in the rate of preterm birth. However, such benefit has not been demonstrated for patients with bacterial vaginosis, or women who carry Streptococcus agalactia, Ureaplasma urealyticum or Trichomonas vaginalis. Antibiotic administration to patients with preterm premature rupture of membranes is associated with prolongation of pregnancy and a reduction in the rate of clinical chorioamnionitis and neonatal sepsis. The benefit has not been demonstrated in patients with preterm labor and intact membranes. Major efforts are required to determine why some women develop an ascending intrauterine infection and others do not and also what interventions may reduce the deleterious effect of systemic fetal inflammation.

  6. Utilization of the Premature Birth Knowledge Scale to Assess Pediatric Provider Knowledge of Neurodevelopmental Outcomes.

    Kelly, Michelle M; Dean, Spencer

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

    Increasing rates of preterm births coupled with better survival of these infants have resulted in higher prevalence of systemic and ocular complications associated with prematurity. In addition to retinopathy of prematurity, infants who are born preterm may suffer from severe visual impairment as a result of hypoxic ischemic encephalopathy, hypoglycemia, and other metabolic imbalances. The effect of these processes on the anterior visual pathway may result in optic atrophy, optic nerve hypoplasia or optic disc cupping and affection of the posterior visual pathway leads to cortical visual impairment (CVI). Other ocular associations include strabismus, nystagmus, and ocular motor abnormalities such as tonic down gaze and defective saccades and pursuits. Cortical and subcortical involvement also manifests as defects in functional vision and these have not yet been completely understood. Children with CVI may have visual field defects, photophobia, defective visual processing, and deficient color vision. Since most of these children also suffer from additional systemic disabilities, evaluation, and management remains a challenge. However, early diagnosis and initiation of rehabilitation therapy can prove to be of significant benefit in these children.

    The dusty, ionized gas cloud G2 is currently passing the massive black hole in the Galactic Center at a distance of roughly 2400 Schwarzschild radii. We explore the possibility of a starting point of the cloud within the disks of young stars. We make use of the large amount of new observations in order to put constraints on G2's origin. Interpreting the observations as a diffuse cloud of gas, we employ three-dimensional hydrodynamical adaptive mesh refinement (AMR) simulations with the PLUTO code and do a detailed comparison with observational data. The simulations presented in this work update our previously obtained results in multiple ways: (1) high resolution three-dimensional hydrodynamical AMR simulations are used, (2) the cloud follows the updated orbit based on the Brackett-$\\gamma$ data, (3) a detailed comparison to the observed high-quality position-velocity diagrams and the evolution of the total Brackett-$\\gamma$ luminosity is done. We concentrate on two unsolved problems of the diffuse cloud scen...

    Prematurely born individuals have an increased risk for long-term neurocognitive impairments. In animal models, development of the cholinergic basal forebrain (cBF) is selectively vulnerable to adverse effects of perinatal stressors, and impaired cBF integrity results in lasting cognitive deficits. We hypothesized that cBF integrity is impaired in prematurely born individuals and mediates adult cognitive impairments associated with prematurity. We used magnetic resonance imaging-based volumetric assessments of a cytoarchitectonically defined cBF region of interest to determine differences in cBF integrity between 99 adults who were born very preterm and/or with very low birth weight and 106 term-born control subjects from the same birth cohort. Magnetic resonance imaging-derived cBF volumes were studied in relation to neonatal clinical complications after delivery and intelligence measures (IQ) in adulthood. In adults who were born very preterm and/or with very low birth weight, cBF volumes were significantly reduced compared with term-born adults (-4.5% [F1,202 = 11.82, p = .001]). Lower cBF volume in adults who were born very preterm and/or with very low birth weight was specifically associated with both neonatal complications (rpart,92 = -.35, p premature birth and links neonatal complications with long-term cognitive outcome. Data suggest that cholinergic system abnormalities may play a relevant role for long-term neurocognitive impairments associated with premature delivery.

  14. Prenatal Stress, Prematurity, and Asthma.

    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.

    To determine the birth prevalence of congenital heart defects (CHDs) across the spectrum of common defects in very/extremely premature infants and to compare mortality rates between premature infants with and without CHDs. The Kids' Inpatient Databases (2003-2012) were used to estimate the birth prevalence of CHDs (excluding patent ductus arteriosus) in very/extremely premature infants born between 25 and 32 weeks' gestational age. Birth prevalence was compared with term infants for a subset of "severe" defects expected to be near universally diagnosed in the neonatal period. Weighted multivariable logistic regression was used to calculate aORs of mortality comparing very and extremely premature infants with vs without CHDs. We identified 249 011 very/extremely premature infants, including 28 806 with CHDs. The overall birth prevalence of CHDs was 116 per 1000 very/extremely premature births. Severe CHDs had significantly higher birth prevalence in very/extremely premature infants when compared with term infants (7.4 per 1000 very/premature births vs 1.5 per 1000 term births; P premature infants with severe CHDs had an overall 26.3% in-hospital mortality and a 7.5-fold increased adjusted odds of death compared with those without CHDs. Mortality varied widely by defect in very/extremely premature infants, ranging from 12% for interrupted aortic arch to 67% for truncus arteriosus. Given the increased birth prevalence of severe CHDs in very/extremely premature infants, and significantly higher mortality, there is justification for intensive interventions aimed at decreasing the likelihood of premature delivery for patients where CHD is diagnosed in utero.

    2002-09-01

    The differences between adolescents born pre-term (n = 50) and a matched sample of adolescents born full-term were examined in relation to fear of personal death, attachment styles, and the relation between the two variables. Findings revealed that adolescents born pre-term showed a higher level of fear of personal death and a lower frequency of secure attachment style than adolescents born full-term. In addition, secure full-term born adolescents exhibited a lower level of fear of personal death compared with insecure adolescents; whereas among those born pre-term, attachment styles did not affect the level of fear of personal death. Results are discussed in terms of the long-term impact of premature birth on affect regulation in adolescence.

  17. Premature ovarian failure

    2012-01-01

    Full Text Available Premature ovarian failure (POF is the occurrence of hypergonadotropic hypoestrogenic amenorrhea in women under the age of forty years. It is idiopathic in 74-90% patients. Known cases can be divided into primary and secondary POF. In primary POF genetic aberrations can involve the X chromosome (monosomy, trisomy, translocations, deletions or autosomes. Genetic mechanisms include reduced gene dosage and non-specific chromosome effects impairing meiosis, decreasing the pool of primordial follicles and increasing atresia due to apoptosis or failure of follicle maturation. Autoimmune ovarian damage is caused by alteration of T-cell subsets and T-cell mediated injury, increase of autoantibody producing B-cells, a low number of effector/cytotoxic lymphocyte, which decreases the number and activity of natural killer cells. Bilateral oophorectomy, chemotherapy, radiotherapy and infections cause the secondary POF. Symptoms of POF include irritability, nervousness, loss of libido, depression, lack of concentration, hot flushes, weight gaining, dry skin, vaginal dryness, frequent infections etc. The diagnosis is confirmed by the level of FSH of over 40 IU/L and estradiol below 50 pmol/L in women aged below 40 years. Biochemical and other hormonal analysis (free thyroxin, TSH, prolactin, testosterone, karyotype (<30 years of age, ultrasound of the breasts and pelvis are advisable. Optimal therapy is combined estrogen progestagen therapy given in a sequential rhythm, after excluding absolute contraindications. Testosterone can be added to adnexectomized women and those with a low libido. Sequential estrogen progestagen replacement therapy is the first line therapy for ovulation induction in those looking for pregnancy and after that oocyte donation will be advised. Appropriate estro-progestagen therapy improves the quality of life and prevents complications such as cardiovascular diseases, osteoporosis, stroke etc.

The prevalent tendency for lower response in CST and CT between the premature children in group G3 and Farnsworth color test in G1 is a curious result of this work and more study is necessary about these visual functions in older premature children. Conclusion: The visual functions showed no statistically significant difference among the groups studied.

  20. Premature ovarian insufficiency: Pathogenesis and management

    Directory of Open Access Journals (Sweden)

    Anna J Fenton

    2015-01-01

    Full Text Available The term premature ovarian insufficiency (POI describes a continuum of declining ovarian function in a young woman, resulting in an earlier than average menopause. It is a term that reflects the variable nature of the condition and is substantially less emotive than the formerly used "premature ovarian failure" which signaled a single event in time. Contrary to the decline in the age of menarche seen over the last 3-4 decades there has been no similar change in the age of menopause. In developed nations, the average age for cessation of menstrual cycles is 50-52 years. The age is younger among women from developing nations. Much has been written about POI despite a lack of good data on the incidence of this condition. It is believed that 1% of women under the age of 40 years and 0.1% under the age of 30 years will develop POI. Research is increasingly providing information about the pathogenesis and treatments are being developed to better preserve ovarian function during cancer treatment and to improve fertility options. This narrative review summarizes the current literature to provide an approach to best practice management of POI.

    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.

    2006-01-01

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

  8. Modern Approach in Premature Ovarian Failure

    Full Text Available Premature ovarian failure (POF is a condition affecting 1-2% of women younger than 40 years of age, characterized by amenorrhea, hypoestrogenism and elevated gonadotropin levels. In the last years it became a problem of social health interest as the frequency increased due to environmental factors and new, efficient methods for cancer treatment in young women. Few genes have beed identified to explain cases of POF but there are also autoimmune associated conditions and an increasing number of iatrogenic cases (chemotherapy, surgery, radiotherapy. Modern approach in POF means not only a precise etiological diagnosis, but also a correct counseling for these patients who often want to become parents, and a chance for a healthy life without the long term consequences of estrogen deprivation from an early age. In vitro fertilization (IVF techniques can be useful for certain cases but research is needed on strategies to improve fertility for women who have follicles remaining in the ovaries.

    Full Text Available Abstract Background It remains unclear whether it is more detrimental to be born too early or too small in relation to symptoms of attention deficit/hyperactivity disorder (ADHD. Thus, we tested whether preterm birth and small body size at birth adjusted for gestational age are independently associated with symptoms of ADHD in children. Methods A longitudinal regional birth cohort study comprising 1535 live-born infants between 03/15/1985 and 03/14/1986 admitted to the neonatal wards and 658 randomly recruited non-admitted infants, in Finland. The present study sample comprised 828 children followed up to 56 months. The association between birth status and parent-rated ADHD symptoms of the child was analysed with multiple linear and logistic regression analyses. Results Neither prematurity (birth Conclusions Intrauterine growth restriction, reflected in SGA status and lower birth weight, rather than prematurity or lower gestational age per se, may increase risk for symptoms of ADHD in young children.

    Full Text Available The aim of this study was to estimate the incidence of retinopathy of permaturity (ROP and to evaluate possible neonatal risk factors for ROP. The main study was a cross-sectional study including 150 high-risk neonates born at teaching hospitals of Tehran universities referring to to Farabi Eye Hospital. The chossing critertia were birth weight less than 2500 g or gestational age younger than 37 weeks. ROP was present in 9(6% newborns, all of whom aged less than 32 weeks a birth. There was also strong association between ROP and birth weight, oxygen administration, respiratory distress syndrome and intraventricular hemorrhage. There also seems to be a higher risk for developing ROP in female neoates, those who were born by multiple gestaional pregnancies or were treated by phototherapy or transfusion and those who had suffered from bronchopulmonary dysplasia or seiss.Prematurity per se remains the strongest risk factof for ROP. Suitable criteria for screening of ROP seems to be gestational age younger than 32 weeks or birth weight less than 1500 g

    This study evaluated the prevalence of enamel defects and dental caries and their risk factors on primary and permanent dentitions of prematurely-born children and term children. Eighty children were examined, 40 born prematurely (G1) and 40 born term (G2), in the age group between 5 and 10 years. The demographic variables, medical history and oral health behaviors were recorded on a questionnaire. The teeth were examined for presence of deficiencies of the enamel and caries that were registered. The caries were registered, focusing on the indices dmft (decayed, missing, and filled primary teeth) and DMFT (decayed, missing, and filled permanent teeth). The results showed that 75% of the total sample had enamel defects. The logistic regression model showed that other risk factors such as per capita family income, educational level, dietary and hygiene habits, fluoride exposure, trauma, and diseases had no correlation with enamel defects and caries. A smaller value of total DMFT (0.95) was found in the group of premature children in comparison to the term children (2.07) p = 0.0164. There was no difference concerning the permanent dentition between the two groups (p = 0.9926). One concludes that prematurity can't be a predisposing factor for the presence of dental caries.

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

  4. Beryllium induces premature senescence in human fibroblasts.

    2007-07-01

    After cells have completed a sufficient number of cell divisions, they exit the cell cycle and enter replicative senescence. Here, we report that beryllium causes proliferation arrest with premature expression of the principal markers of senescence. After young presenescent human fibroblasts were treated with 3 microM BeSO(4) for 24 h, p21 cyclin-dependent kinase inhibitor mRNA increased by >200%. Longer periods of exposure caused mRNA and protein levels to increase for both p21 and p16(Ink4a), a senescence regulator that prevents pRb-mediated cell cycle progression. BeSO(4) also caused dose-dependent induction of senescence-associated beta-galactosidase activity (SA-beta-gal). Untreated cells had 48 relative fluorescence units (RFU)/microg/h of SA-beta-gal, whereas 3 microM BeSO(4) caused activity to increase to 84 RFU/microg/h. In chromatin immunoprecipitation experiments, BeSO(4) caused p53 protein to associate with its DNA binding site in the promoter region of the p21 gene, indicating that p53 transcriptional activity is responsible for the large increase in p21 mRNA elicited by beryllium. Forced expression of human telomerase reverse transcriptase (hTERT) rendered HFL-1 cells incapable of normal replicative senescence. However, there was no difference in the responsiveness of normal HFL-1 fibroblasts (IC(50) = 1.9 microM) and hTERT-immortalized cells (IC(50) = 1.7 microM) to BeSO(4) in a 9-day proliferation assay. The effects of beryllium resemble those of histone deacetylase-inhibiting drugs, which also cause large increases in p21. However, beryllium produced no changes in histone acetylation, suggesting that Be(2+) acts as a novel and potent pharmacological inducer of premature senescence.

  5. Prematurity and Programming Contribution of neonatal (NICU) interventions

    2014-01-01

    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

    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.

    Full Text Available 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 Brasindice 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.

    The authors report the formation of hard exudates and macular scarring after laser photocoagulation therapy in patients with retinopathy of prematurity (ROP). Two premature neonates, the first born at 24 weeks and the second at 25 weeks gestational age, were diagnosed as having ROP that necessitated laser photocoagulation treatment at 32 and 36 weeks, respectively. Subretinal fluid and macular hard exudation developed in both patients that eventually caused bilateral macular scarring. Subretinal macular fluid with hard exudation could lead to macular scar formation in neonates with ROP after laser photocoagulation that could significantly affect the visual prognosis in preterm infants.

    The new practice guideline on the treatment of extremely premature infants is discussed. The guideline advises to actively treat all children born after 24 0/7 weeks of gestation. Although there is some evidence supporting this view, it is argued that the guideline is incomplete as decisions about the treatment of such newborn infants can only be made after discussion with the parents. The guideline should also have taken into account the ethical and legal aspects of the issue. It is therefore concluded that the guideline itself is immature and premature.

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

    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.

    Boguszewski, Margaret Cristina da Silva; Cardoso-Demartini, Adriane de Andre

    2017-03-01

    Approximately 15 million babies are born preterm across the world every year, with less than 37 completed weeks of gestation. Survival rates increased during the last decades with the improvement of neonatal care. With premature birth, babies are deprived of the intense intrauterine growth phase, and postnatal growth failure might occur. Some children born prematurely will remain short at later ages and adult life. The risk of short stature increases if the child is also born small for gestational age. In this review, the effects of being born preterm on childhood growth and adult height and the hormonal abnormalities possibly associated with growth restriction are discussed, followed by a review of current information on growth hormone treatment for those who remain with short stature during infancy and childhood.

  17. Detecting rickets in premature infants and treating them with calcitriol: experience from two cases.

    Chen, Hung-Yi; Chiu, Li-Chien; Yek, Yung-Lee; Chen, Yi-Ling

    2012-08-01

    A premature infant is a baby born before 37 weeks of gestation. Rickets is a bone disease characterized by growth retardation due to the expansion of the hypertrophic chondrocyte layer of the growth plate and a failure to mineralize bone. Consequently, the bone is soft and permits marked bending and distortion. Although the incidence of rickets in preterm infants is lower due to improvements in health care and nutrition, there are still infants at high risk for this disease. However, few reports are available regarding the treatment of rickets in premature infants. Furthermore, published case studies on experiences with using calcitriol as a potential therapeutic for rickets in premature infants are very rare. Herein, we describe the detection of rickets in premature infants and our experience with calcitriol treatment in two premature infants. We recommended the use of oral calcitriol at a dose of 0.03-0.125 μg/kg/day, in addition to an appropriate formula that provides an adequate amount of calcium and phosphate intake. One patient was prescribed calcitriol for 40 days and the other for 37 days. The two infants gradually recovered and were discharged without any obvious side effects. It is recommended that alkaline phosphatase levels be monitored within 1 month after birth in premature infants with a birth weight of <1000 g. Infants presenting with high alkaline phosphatase levels are candidates for a long bone survey.

    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.

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

  20. Positional moulding in premature hydrocephalics.

    Full Text Available Seven premature hydrocephalics presenting with lambdoid positional moulding (LPM were reviewed. All were treated for hydrocephalus secondary to aqueductal stenosis, Dandy Walker Syndrome and infection. Parenchymal hemorrhage, intraventricular bleed, cortical atrophy, septal agenesis, cortical anomalies and subdural hygroma were the other common associations. These children did not show expected improvement in their higher mental functions at 6 months to 5.4 years of follow-up, following the management of hydrocephalus. It was not the LPM but associated intracranial anomalies, which were most probably responsible for their poor outcome. The differentiation from posterior plagiocephaly is also highlighted.

    2014-09-01

    Full Text Available Metabolic bone disease (MBD of prematurity remains a significant problem for preterm, chronically ill neonates. The definition and recommendations for screening and treatment of MBD vary in the literature. A recent American Academy of Pediatrics Consensus Statement may help close the gap in institutional variation, but evidence based practice guidelines remain obscure due to lack of normative data and clinical trials for preterm infants. This review highlights mineral homeostasis physiology, current recommendations in screening and monitoring, prevention and treatment strategies, and an added perspective of a bone health team serving a high volume referral neonatal intensive care center.

    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.

    A prominent theoretical view is that the brain is inherently predictive [1, 2] and that prediction helps drive the engine of development [3, 4]. Although infants exhibit neural signatures of top-down sensory prediction [5, 6], in order to establish that prediction supports development, it must be established that deficits in early prediction abilities alter trajectories. We investigated prediction in infants born prematurely, a leading cause of neuro-cognitive impairment worldwide [7]. Prematurity, independent of medical complications, leads to developmental disturbances [8-12] and a broad range of developmental delays [13-17]. Is an alteration in early prediction abilities the common cause? Using functional near-infrared spectroscopy (fNIRS), we measured top-down sensory prediction in preterm infants (born identification of infants at risk and could guide early intervention regimens.

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

    The mothers of premature infant born 7 years ago were interviewed regarding memory of neonatal hospitalization during a 40-minute phone interview using a questionnaire exploring emotional feeling and satisfaction. The memory of a high emotional feeling was significantly associated with cranial ultrasound abnormalities in neonatal period, but not outcome. Dissatisfaction was reduced by antenatal maternal hospitalization. We speculate that medical information gathered during perinatal hospitalization explains these relationships.

    Hughes, J R; Fino, J J; Hart, L A

    1987-07-01

    A distinctive pattern called premature temporal theta (PT theta) was studied in 436 infants, ranging in age from 24 to 46 weeks. The pattern is seen in early prematurity, maximizes at 29-31 weeks and then diminishes and disappears near term. Usually the pattern is found independently on both temporal areas, but with a right-sided preference. Patients without PT theta or with a significantly low amount had either neurological or non-neurological (medical) conditions. With age there is a tendency for an increase in frequency and a decrease in amplitude. Five different peaks in the amount of this pattern are seen at approximately every month. Unilateral PT theta tends to be seen in older babies, more often on the right side and with an abnormal EEG. An abnormal EEG is usually associated with a delay in both the appearance and disappearance of this wave form. PT theta is also associated mainly with REM or active sleep. A polynomial rather than an exponential or power function best describes these data with changes of age. PT theta may arise from the inferior temporal gyrus and/or especially the transverse gyrus.

    2016-02-01

    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.

  17. The role of transient hypothyroxinemia of prematurity in development of visual abilities.

    Science.gov (United States)

    Rovet, Joanne; Simic, Nevena

    2008-12-01

    Preterm birth is associated with an increased risk of visual impairment. However, not all visual deficits can be fully explained by the typical prematurity morbidity factors. In addition, children born preterm often exhibit transient hypothroxinemia of prematurity (THOP) due to premature severing of the maternal supply of thyroid hormones. Because thyroid hormone is critically needed for multiple facets of early brain development, including the structures needed for visual processing, and because the maternal thyroid supply is essential throughout pregnancy, it is possible that THOP contributes to the visual impairments seen in preterm children. To test this hypothesis, we used both clinical tests and visual-evoked potential techniques to assess visual abilities in two cohorts of preterm infants whose thyroid hormone levels were measured in the perinatal period. In the first cohort born 30 to 35 weeks gestation, we found associations between low thyroid hormone levels and reduced visual attention at 3 months corrected age (Study 1) and poor visuomotor abilities at 12 and 18 months corrected age (Study 2). In the second cohort born 23 to 35 weeks gestation, THOP severity was negatively correlated with attention at 3 months corrected age (Study 3) and contrast sensitivity and color vision at 6 months corrected age (Study 4). These findings therefore suggest that thyroid hormone is necessary for the development of early visual abilities and that THOP may partially explain the visual deficits of preterm infants.

    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.

    We studied the associations of size at birth and prematurity with type 2 diabetes, insulin sensitivity and beta cell function in the Danish population-based Inter99 study (ClinicalTrials.gov NCT00289237). Information about size at birth and prematurity was identified from original midwife records in 4,744 middle-aged Danes. Type 2 diabetes status, insulin sensitivity (Matsuda index) and beta cell function (disposition index) were assessed using a 75 g oral glucose tolerance test. Participants born prematurely were compared with a group of at-term participants born small for gestational age. An increase in birthweight of 1 kg was associated with a 51% (OR 0.49, 95% CI 0.35-0.69) reduced risk of type 2 diabetes. Ponderal index, reflecting thinness at birth, was associated with type 2 diabetes to the same extent as birthweight. The prevalence of type 2 diabetes was increased to a similar degree in participants born prematurely and participants born small for gestational age, although the former had a higher ponderal index at birth. In addition, birthweight z-scores, reflecting fetal growth rate, were unrelated to the risk of type 2 diabetes and to other measures of glucose regulation in participants born prematurely. While low birthweight was inversely associated with insulin sensitivity and beta cell function, prematurity was associated solely with decreased insulin sensitivity. While the association between birthweight and risk of type 2 diabetes is mediated via combined effects on beta cell function and insulin sensitivity, prematurity seems to influence risk of type 2 diabetes via attenuated insulin sensitivity only and independently of fetal growth rates.

    Scientific evidence is insufficient to answer the question of whether premature birth causes altered tooth-crown dimensions. To evaluate permanent tooth-crown dimensions in prematurely born children and to compare the findings with full-term born controls. Preterm children of 8-10 years of age were selected from the Swedish Medical Birth Register. One group consisted of 36 extremely preterm children (born before the 29th gestational week); the other group included 37 very preterm children (born during gestational weeks 29-32). The preterm children were compared with 41 matched full-term born children. Clinical examination and study casts were performed on all children. Permanent maxillary and mandibular first molars, central incisors, and laterals were measured with a digital sliding caliper on study casts. The tooth-crowns were measured both mesio-distal and bucco-lingual. Both the mesio-distal and bucco-lingual measurements in the maxillary and mandibular first molars had a significantly smaller width in the extremely preterm group compared with the full-term group. The central incisors and lower laterals were significantly smaller mesio-distally in the extremely preterm group compared to the full-term group. A reduction in tooth size of 4-9% was found between the extremely preterm group and the full-term group for both boys and girls. The maxillary first molars and mandibular left first molar were also smaller mesio-distally in the extremely preterm group compared to the very preterm group. The results indicate that the more preterm the birth, the smaller the tooth-crown dimensions. Independent of gestational age girls had generally smaller teeth than boys. Premature birth is associated with reduced tooth-crown dimensions of permanent incisors and first molars.

Among infants with type 1, type 2, or no retinopathy of prematurity, the incidence of type 1 or type 2 retinopathy of prematurity in births from spontaneous preterm labor, medical indication of preterm birth, and preterm premature rupture of the membranes was 37 of 218 (17%), 27 of 272 (10%), and 10 of 164 (6%), respectively. Adjusted for gestational age, birth weight, and multiparity and compared with the preterm premature rupture of the membranes group, the odds ratios of spontaneous preterm labor and medical indication of preterm birth for type 1 or type 2 retinopathy of prematurity were 6.1 (95% confidence interval, 1.8 to 20, P = .003) and 5.5 (95% confidence interval, 1.4 to 21, P = .01), respectively. Among neonates born after preterm premature rupture of the membranes, the probability of developing type 1 or type 2 retinopathy of prematurity was greatest in infants with rupture of membrane duration of up to 24 hours. After 24 hours, the probability of developing type 1 or type 2 retinopathy of prematurity declined. The odds of developing type 1 or type 2 retinopathy of prematurity was 9.0 (95% confidence interval 2.3 to 34, P = .002) in infants who had preterm premature rupture of the membranes ≤ 24 hours compared with infants who had preterm premature rupture of the membranes > 24 hours. Type 1 or type 2 retinopathy of prematurity are adverse ocular outcomes linked with not only lower gestational age and birth weight at delivery but also with events in the intrauterine environment that trigger a preterm birth. The reduced incidence of type 1 or type 2 retinopathy of prematurity in the preterm premature rupture of the membranes group compared with other causes of preterm birth may be

    Sex allocation theories predict equal offspring number of both sexes unless differential investment is required or some competition exists. Left undisturbed, elephants reproduce well and in approximately even numbers in the wild. We report an excess of males are born and substantial juvenile mortality occurs, perinatally, in captivity. Studbook data on captive births (CB, n=487) and premature deaths (PD, 6 months with maternal insufficient milk production, natural hazards and accidents being the main causes. European Asian and Myanmar elephants PD was biased towards males (0.71, P=0.024 and 0.56, P<0.001, respectively). The skewed birth sex ratio and high juvenile mortality hinder efforts to help captive populations become self-sustaining. Efforts should be invested to identify the mechanism behind these trends and seek solutions for them.

    2013-08-01

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

    To investigate the influence of prenatal hospitalization before a premature birth, on the parental stressful experience, parental symptoms of post-traumatic stress and quality of parent-infant interaction during the hospitalization in neonatology. 51 preterm infants born and 25 full term infants control. Four groups: controls, premature without prenatal hospitalization, premature with a short (premature with a long (≥ 8 days) prenatal hospitalization. the Parental Stressor Scale: Neonatal Intensive Care Unit (PSS: NICU, Miles et al., 1993 [14]) and the Perinatal PTSD Questionnaire (PPQ, Quinnell and Hynan, 1999 [16]). When prenatal hospitalization of the mother occurred, parents acknowledged increased stress induced by the environmental factors during the infant's hospitalization. Furthermore, mothers from the group with a short prenatal hospitalization presented significantly more symptoms of post-traumatic stress. Parents presenting more symptoms of post-traumatic stress describe a significantly more difficult interaction with their infant in neonatology. This study highlights the necessity to deliver special care to women hospitalized shortly (premature baby. This group is at high risk of presenting post-traumatic stress symptoms, which could have a negative impact on the quality of parent-infant interactions. Copyright © 2012.

  8. Iatrogenic Anetoderma of Prematurity: A Case Report and Review of the Literature

    Laura Maffeis

    2014-01-01

    Full Text Available Anetoderma is a skin disorder characterized by focal loss of elastic tissue in the mid dermis, resulting in localized areas of macular depressions or pouchlike herniations of skin. An iatrogenic form of anetoderma has been rarely described in extremely premature infants and has been related to the placement of monitoring devices on the patient skin. Because of the increasing survival of extremely premature infants, it is easy to foresee that the prevalence of anetoderma of prematurity will increase in the next future. Although it is a benign lesion, it persists over time and can lead to significant aesthetic damage with need for surgical correction. Sometimes the diagnosis can be difficult, especially when the atrophic lesions become evident after discharge. Here, we report on a premature infant born at 24 weeks of gestation, who developed multiple anetodermic patches of skin on the trunk at the sites where electrocardiographic electrodes were previously applied. The knowledge of the disease can encourage a more careful management of the skin of extremely premature babies and aid the physicians to diagnose the disease when anetoderma patches are first encountered later in childhood.

  11. [Premature rupture of membranes and chorioamnionitis].

    Lopez Garcia, R

    1988-01-01

    Despite advances in perinatal medicine in the past decade, the diagnosis and treatment of premature rupture of membranes remain controversial. Premature rupture occurs in 2.7-7.0% of pregnancies and most cases occur spontaneously without apparent cause. The disparity in reported rates of premature rupture is due to differences in the definition and diagnostic criteria for premature rupture and lack of comparability in the populations studied. Mexico's National Institute of Perinatology has adopted the definition of the American COllege of Gynecology and Obstetrics which views premature rupture as that occurring before regular uterine contractions that produce cervical dilation. 8.8% of its patients have premature rupture according to this definition. 20% of cases occur before the 36th week of pregnancy. Treatment of rupture occurring before 37 weeks must balance the threat of amniotic infection with the dangers of premature birth. Infections appear more common in low income patient populations. Chorioamnionitis is a serious complication of pregnancy and is the main argument against conservative treatment of premature rupture. The rate of maternal infection is directly related to the time elapsing between rupture of the membranes and birth. The rate increases after the 1st 24 hours and is at least 10 times higher after 72 hours. But recent studies suggest that there is no considerable increase in infection if vaginal explorations are avoided and careful techniques are used in treating the patient. Those who advise conservative treatment believe that prenatal outcomes are better because respiratory disease syndrome due to prematurity is avoided. Conservative management requires a white cell count at least every 24 hours and measurement of pulse, maternal temperature, and fetal heart rate ideally every 4 hours. Perinatal mortality rates due to premature rupture of membranes range from 2.5-50%. The principal causes are respiratory disease syndrome, infection, asphyxia

    Full Text Available BACKGROUND Prematurity refers to live births before 37 weeks of gestation, wherein the baby is born before the body and its organ systems achieve perfect maturity, and this disorder is still a global problem. The high incidence of prematurity is a problem in developing and also in developed countries. Certain conditions accompanying pregnancies like preeclampsia, infection, and placental insufficiency, may trigger uterine hypoxia, causing premature birth. The placental condition is related to the intra-uterine fetal condition. In prolonged placental hypoxia, there occurs a compensatory mechanism, i.e. an increase in placental angiogenesis. This study aimed to evaluate the effect of hypoxia on fetal blood vessel count as compensatory mechanism for tissue hypoxia. METHODS An observational-analytical cross-sectional design using paraffin blocks of conserved premature placentas, comprising 31 samples of hypoxic premature placentas and 28 samples of non-hypoxic premature placentas, selected using non-random consecutive sampling. The samples were made into slides and stained with hematoxylin-eosin for assessment of histological structure, including fetal blood vessel count and integrity, villus conditions, syncytiotrophoblastic nuclear changes, and syncytiotrophoblastic nuclear aggregation. Mann-Whitney test was used to compare the difference of blood vessel count between groups. RESULTS Assessment of histological structure showed a significant increase in fetal blood vessel count in the hypoxic group [8.00 (5-15] as compared with the non-hypoxic group [7.50 (3-15]. CONCLUSION The hypoxia in premature placentas caused an increase in the number of fetal blood vessels as a form of compensation for disturbed oxygen homeostasis.

    Full Text Available 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.

  16. Human milk for the premature infant

    Underwood, Mark A.

    2012-01-01

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

  17. Adolescent Premature Ovarian Insufficiency Following Human Papillomavirus Vaccination

    Directory of Open Access Journals (Sweden)

    Deirdre Therese Little MBBS, DRANZCOG, FACRRM

    2014-10-01

    Full Text Available 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.

    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.

    2015-01-01

    Full Text Available 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.

    The kidney plays a central role in the clearance of drugs. However, renal drug handling entails more than glomerular filtration and includes tubular excretion and reabsorption, and intracellular metabolization by cellular enzyme systems, such as the Cytochrome P450 isoenzymes. All these processes show maturation from birth onwards, which is one of the reasons why drug dosing in children is not simply similar to dosing in small adults. As kidney development normally finishes around the 36th week of gestation, being born prematurely will result in even more immature renal drug handling. Environmental effects, such as extra-uterine growth restriction, sepsis, asphyxia, or drug treatments like caffeine, aminoglycosides, or non-steroidal anti-inflammatory drugs, may further hamper drug handling in the kidney. Dosing in preterm neonates is therefore dependent on many factors that need to be taken into account. Drug treatment may significantly hamper postnatal kidney development in preterm neonates, just like renal immaturity has an impact on drug handling. The restricted kidney development results in a lower number of nephrons that may have several long-term sequelae, such as hypertension, albuminuria, and renal failure. This review focuses on the interplay between drugs and the kidney in premature neonates.

    To compare regional cerebellar microstructure, as measured by diffusion tensor imaging (DTI), between preterm infants at term-equivalent age and healthy term-born control neonates, and to explore associations between DTI findings and clinical risk factors. In this case-control study, DTI studies were performed in 73 premature infants born ≤32 weeks and ≤1500 g birth weight and 73 full-term-born controls from healthy pregnancies. Using a region of interest approach, fractional anisotropy (FA) and mean diffusivity (MD) were extracted in 7 cerebellar regions including the anterior vermis, the right/left superior cerebellar peduncles, the middle cerebellar peduncle, and the dentate nuclei. To validate further our DTI measurements, we measured FA and MD in the genu of the corpus callosum and splenium. FA and MD were compared between groups using analyses of multiple linear regression models. Preterm infants at term-equivalent age presented with higher FA in the dentate nuclei (premature birth are associated with altered cerebellar microstructural organization when compared with term-born control infants.

    To examine the relationships between growth (birth to age 2 years) and developmental outcomes in children born with very low birthweight (VLBW). Motor and mental development in children born with VLBW were regressed on anthropometric measurements at birth, 9 months and 2 years using multivariable regression. The Early Childhood Longitudinal Study-Birth Cohort, a longitudinal cohort, community sample, designed to be representative of children born across the USA. 950 children born with VLBW (children exhibited poor growth, with length-for-age z-scores children at 9 months (adjusted for prematurity) and 34.2% of children at 2 years. Compared with children having z-scores >-2, children with growth shortfalls in head circumference, length and weight had a higher adjusted OR (aOR) of low Bayley motor scores at 9 months and 2 years (aOR ranging from 1.8 to 3.3, all pchildren born with VLBW. While careful length measures may be a particularly useful marker, deficits in all anthropometric measures were risk factors for developmental delays. Published by the BMJ Publishing Group Limited.

    Meijers Ruud WJ

    2012-09-01

    Full Text Available Abstract Background End-stage renal disease (ESRD patients treated with renal replacement therapy (RRT have premature immunologically aged T cells which may underlie uremia-associated immune dysfunction. The aim of this study was to investigate whether uremia was able to induce premature ageing of the T cell compartment. For this purpose, we examined the degree of premature immunological T cell ageing by examining the T cell differentiation status, thymic output via T cell receptor excision circle (TREC content and proliferative history via relative telomere length in ESRD patients not on RRT. Results Compared to healthy controls, these patients already had a lower TREC content and an increased T cell differentiation accompanied by shorter telomeres. RRT was able to enhance CD8+ T cell differentiation and to reduce CD8+ T cell telomere length in young dialysis patients. An increased differentiation status of memory CD4+ T cells was also noted in young dialysis patients. Conclusion Based on these results we can conclude that uremia already causes premature immunological ageing of the T cell system and RRT further increases immunological ageing of the CD8+ T cell compartment in particular in young ESRD patients.

    Turko, B.

    1980-01-01

    The Space Borne Event Timer is a part of the NASA laser ranging system that is intended to operate aboard the Space Shuttle orbiting over California. The object is to measure, by laser ranging, the earth movement along the San Andreas fault and possibly forecast future earthquakes. A number of cube reflector targets will be placed along both sides of the fault. The ranging system aboard the Space Shuttle will fire a burst of laser pulses at each target and detect the reflected light. Time differences between pulses from the two sides of the fault will indicate earth displacements. The Space Borne Event Timer is a CAMAC compatible system that provides extremely accurate timing data and controls the operation of the ranging system. For each event the time is given in 19.53 increments from the instant of firing the laser to the instant the reflected light is received back, within a range of 130 days.

    Botulism is a neuroparalytic disease caused by neurotoxins produced by Clostridium botulinum, and classically presents as palsies of cranial nerves and acute descending flaccid paralysis. Food-borne botulism is the most common form of botulism, and caused by preformed neurotoxins produced by Clostridium botulinum. Electrophysiological studies play an important role in the early diagnosis. Confirmation of the diagnosis is based on the detection of botulinum toxins in the patient's serum or stool. In Japan, decades ago, botulism type E occurred, though only sporadically, almost every year, but in recent years, has dramatically decreased in frequency. Botulism is a curable disease when treated early and adequately. Differential diagnosis of cranial nerves and limb muscle palsies with rapid exacerbation should include food-borne botulism.

    2015-09-01

    Presentation, prognosis, and management of premature ventricular complexes (PVCs) vary significantly among patients and depend on PVC characteristics as well as patient comorbidities. Presentation can range from incidental discovery in an asymptomatic patient to debilitating heart failure. Prognosis depends on, among other factors, the presence or absence of structural heart disease, PVC burden and other factors detailed in this review. Our understanding of the clinical significance of frequent PVCs, particularly as it relates to development of cardiomyopathy, has advanced greatly in the past decade. In this article, we explore the mechanisms governing PVC initiation and discuss prevalence and frequency of PVCs in the general population. We also explore prognostic implications based on PVC frequency as well as the presence or absence of underlying heart disease. We then take a focused look at PVC-induced cardiomyopathy and identify predictors for developing cardiomyopathy. Finally, we discuss clinical evaluation and management of patients presenting with frequent PVCs. Management can include clinical observation, addressing reversible causes, lifestyle modification, pharmacotherapy, or catheter ablation.

  9. Psychosocial interventions for premature ejaculation

    Tamara Melnik

    Full Text Available BACKGROUND: Premature ejaculation (PE is a very common sexual dysfunction among patients, and with varying prevalence estimates ranging from 3% to 20%. Although psychological issues are present in most patients with premature PE, as a cause or as a consequence, research on the effects of psychological approaches for PE has in general not been controlled or randomised and is lacking in long-term follow up. OBJECTIVE: To assess the efficacy of psychosocial interventions for PE. CRITERIA FOR CONSIDERING STUDIES FOR THIS REVIEW: Trials were searched in computerized general and specialized databases, such as: MEDLINE by PubMed (1966 to 2010; PsycINFO (1974 to 2010; EMBASE (1980 to 2010; LILACS (1982 to 2010; the Cochrane Central Register of Controlled Trials (Cochrane Library, 2010; and by checking bibliographies, and contacting manufacturers and researchers. SELECTION CRITERIA: Randomised or quasi-randomised controlled trials evaluating psychosocial interventions compared with different psychosocial interventions, pharmacological interventions, waiting list, or no treatment for PE. DATA COLLECTION AND ANALYSIS: Information on patients, interventions, and outcomes was extracted by at least two independent reviewers using a standard form. The primary outcome measure for comparing the effects of psychosocial interventions to waiting list and standard medications was improvement in IELT (i.e., time from vaginal penetration to ejaculation. The secondary outcome was change in validated PE questionnaires. MAIN RESULTS: In one study behavioral therapy (BT was significantly better than waiting list for duration of intercourse (MD (mean difference 407.90 seconds, 95% CI 302.42 to 513.38, and couples' sexual satisfaction (MD -26.10, CI -50.48 to -1.72. BT was also significantly better for a new functional-sexological treatment (FS (MD 412.00 seconds, 95% CI 305.88 to 518.12, change over time in subjective perception of duration of intercourse (Women: MD 2

    The relation of sexual behaviour during pregnancy to the initiation of labour was investigated in 358 patients of whom 58 were delivered after premature labour and 300 were delivered spontaneously at term. In all patients the mean weekly coital frequency and the frequency of orgasm were investigated by means of a retrospective questionnaire. There was no significant difference in coital or orgasmic frequency between the women who had a premature labour and those who had a spontaneous delivery at term. This was also true when those having premature labour were divided into those starting labour with ruptured membranes and those starting with contractions.

    A case of acute appendicitis in a premature baby in whom diagnosis was suggested on plain films of the abdomen is presented. In this baby air in a hollow viscus suspected of being an enlarged appendix was the clue to diagnosis. The diagnostic dilemma of this rare and life-threatening condition in premature babies and newborns is underlined. The relevance of different imaging modalities and of different findings in this age group is discussed. Awareness of this rare condition and possible differential diagnosis in newborns and premature babies is stressed. (orig.)

    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.

    Althof, Stanley E

    2016-08-01

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

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

    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.

    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.

    To determine the dynamic morphologic development of the human fovea in vivo using portable spectral domain-optical coherence tomography (SD-OCT). Prospective, observational case series. Thirty-one prematurely born neonates, 9 children, and 9 adults. Sixty-two neonates were enrolled in this study. After examination for retinopathy of prematurity (ROP), SD-OCT imaging was performed at the bedside in nonsedated infants aged 31 to 41 weeks postmenstrual age (PMA) (= gestational age in weeks + chronologic age) and at outpatient follow-up ophthalmic examinations. Thirty-one neonates met eligibility criteria. Nine children and nine adults without ocular pathology served as control groups. Semiautomatic retinal layer segmentation was performed. Central foveal thickness, foveal to parafoveal (FP) ratio (central foveal thickness divided by thickness 1000 μm from the foveal center), and 3-dimensional thickness maps were analyzed. In vivo determination of foveal morphology, layer segmentation, analysis of subcellular changes, and spatiotemporal layer shifting. In contrast with the adult fovea, several signs of immaturity were observed in the neonates: a shallow foveal pit, persistence of inner retinal layers (IRLs), and a thin photoreceptor layer (PRL) that was thinnest at the foveal center. Three-dimensional mapping showed displacement of retinal layers out of the foveal center as the fovea matured and the progressive formation of the inner/outer segment band in the opposite direction. The FP-IRL ratios decreased as IRL migrated before term and minimally after that, whereas FP-PRL ratios increased as PRL subcellular elements formed closer to term and into childhood. A surprising finding was the presence of cystoid macular edema in 58% of premature neonates that appeared to affect inner foveal maturation. This study provides the first view into the development of living cellular layers of the human retina and of subcellular specialization at the fovea in premature infant eyes

    We present a model for an inhomogeneous and anisotropic early universe filled with a nonlinear electromagnetic field of Born-Infeld (BI) type. The effects of the BI field are compared with the linear case (Maxwell). Since the curvature invaria nts are well behaved then we conjecture that our model does not present an initial big bang singularity. The existence of the BI field modifies the curvature invariants at t=0 as well as sets bounds on the amplitude of the conformal metric function

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

  4. Future Applications of Antioxidants in Premature Infants

    2012-01-01

    Purpose of Review This review will examine the unique susceptibility of premature infants to oxidative stress, the role of reactive oxygen species (ROS) in the pathogenesis of common disorders of the preterm infant, and potential for therapeutic interventions using enzymatic and/or non-enzymatic antioxidants. Recent Findings Oxidative stress is caused by an imbalance between the production of ROS and the ability to detoxify them with the help of antioxidants. The premature infant is especially susceptible to ROS-induced damage because of inadequate antioxidant stores at birth, as well as impaired upregulation in response to oxidant stress. Thus, the premature infant is at increased risk for the development of ROS-induced diseases of the newborn, such as bronchopulmonary dysplasia, retinopathy of prematurity, necrotizing enterocolitis, and periventricular leukomalacia. Summary Potential therapies for ROS-induced disease include both enzymatic and non-enzymatic antioxidant preparations. More research is required to determine the beneficial effects of supplemental antioxidant therapy. PMID:21150443

Even if apnea of prematurity is by definition a self-limiting condition, it can cause serious problems during the hospital stay and can potentially have long-term neurological and cognitive consequences depending on the severity and intensity of the episodes. The diagnosis of apnea of prematurity can be made only after excluding a number of diseases of the preterm infant in which apnea may be an epiphenomenon. Etiological diagnosis is essential for selection of appropriate treatment, which may be nonpharmacological or involve use of drugs.Keywords: apnea of prematurity, idiopathic and secondary apnea, caffeine

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

    Purpose Eosinophilia is common in premature infants, and its incidence increases with a shorter gestation period. We investigated the clinical significance of eosinophilia in premature infants born at Eosinophilia was defined as an eosinophil percentage of >3% of the total leukocytes. Perinatal parameters and clinical parameters were also analyzed. Results Of the 261 infants born at eosinophilia at birth. The eosinophil percentage peaked in the fourth postnatal week at 7.5%. The incidence of severe eosinophilia increased after birth up to the fourth postnatal week when 8.8% of all patients had severe eosinophilia. Severity of eosinophilia was positively correlated with a lower gestational age, birth weight, and Apgar score. Respiratory distress syndrome, bronchopulmonary dysplasia, nephrocalcinosis, intraventricular hemorrhage, and sepsis were associated with a higher eosinophil percentage. The eosinophil percentage was significantly higher in infants with bronchopulmonary dysplasia from the first postnatal week and the percentage was the highest in the fourth postnatal week, with the maximal difference being 4.1% (PEosinophilia is common in premature infants and reaches peak incidence and severity in the fourth postnatal week. The eosinophil percentage was significantly higher in bronchopulmonary dysplasia patients from the first postnatal week. Severe eosinophilia was significantly associated with the incidence of bronchopulmonary dysplasia even after adjusting for other variables. PMID:24868214

    A wide range of dilemmas encountered in the health domain can be addressed more efficiently by a transdisciplinary approach. The complex context of extreme prematurity, which is raising important challenges for caregivers and parents, warrants such an approach. In the present work, experts from various disciplinary fields, namely biomedical, epidemiology, psychology, ethics, and law, were enrolled to participate in a reflection. Gathering a group of experts could be very demanding, both in terms of time and resources, so we created a web-based discussion forum to facilitate the exchanges. The participants were mandated to solve two questions: "Which parameters should be considered before delivering survival care to a premature baby born at the threshold of viability?" and "Would it be acceptable to give different information to parents according to the sex of the baby considering that outcome differences exist between sexes?" The discussion forum was performed over a period of nine months and went through three phases: unidisciplinary, interdisciplinary and transdisciplinary, which required extensive discussions and the preparation of several written reports. Those steps were successfully achieved and the participants finally developed a consensual point of view regarding the initial questions. This discussion board also led to a concrete knowledge product, the publication of the popularized results as an electronic book. We propose, with our transdisciplinary analysis, a relevant and innovative complement to existing guidelines regarding the decision-making process for premature infants born at the threshold of viability, with an emphasis on the respective responsabilities of the caregivers and the parents.

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

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

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

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

    BACKGROUND It is unknown why human metapneumovirus (HMPV) and respiratory syncytial virus (RSV) cause severe respiratory infection in children, particularly in premature infants. Our aim was to investigate if there are defective airway antiviral responses to these viruses in young children with history of prematurity. METHODS Nasal airway secretions were collected from 140 children ≤3 y old without detectable virus (n = 80) or with PCR-confirmed HMPV or RSV infection (n = 60). Nasal protein levels of IFNγ, CCL5/RANTES, IL-10, IL-4, and IL-17 were determined using a multiplex magnetic bead immunoassay. RESULTS Full-term children with HMPV and RSV infection had increased levels of nasal airway IFNγ, CCL5, and IL-10 along with an elevation in Th1 (IFNγ)/Th2 (IL-4) ratios, which is expected during antiviral responses. In contrast, HMPV-infected premature children (< 32 wk gestation) did not exhibit increased Th1/Th2 ratios or elevated nasal airway secretion of IFNγ, CCL5, and IL-10 relative to uninfected controls. CONCLUSION Our study is the first to demonstrate that premature infants have defective IFNγ, CCL5/RANTES, and IL-10 airway responses during HMPV infection and provides novel insights about the potential reason why HMPV causes severe respiratory disease in children with history of prematurity.

Sources: the MEDLINE, LILACS, and Cochrane Library databases were searched, and the references of the articles retrieved were also used, with no limit of time. Data synthesis: numerous studies showed a recent increase in late preterm births. In all series, late preterm comprised the majority of preterm births. Studies including millions of births showed a strong association between late preterm birth and neonatal mortality. A higher mortality in childhood and among young adults was also observed. Many studies found an association with several neonatal complications, and also with long-term disorders and sequelae: breastfeeding problems, cerebral palsy, asthma in childhood, poor school performance, schizophrenia, and young adult diabetes. Some authors propose strategies to reduce late preterm birth, or to improve neonatal outcome: use of antenatal corticosteroids, changes in some of the guidelines for early delivery in high-risk pregnancies, and changes in neonatal care for this group. Conclusions: numerous studies show greater mortality and morbidity in late preterm infants compared with term infants, in addition to long-term disorders. More recent studies evaluated strategies to improve the outcomes of these neonates. Further studies on these strategies are needed.

  18. Lowering the premature birth rate: what the U.S. experience means for Japan.

    Premature birth rate and low birth weight rate are increasing in industrialized countries including USA and Japan. The Infant mortality rate (IMR) is three times and 50-75 times greater for infants born at 32-36 weeks and Premature birth is heterogeneous in origin and idiopathic in 70% of the cases. Increased utilization of assisted reproductive technology only accounts for a part of the recent trend. Evidence suggests environmental factors play a significant role, and genetic-environmental interaction is plausible. A chronic psychosocial stress of pregnant women has been postulated to be modifying the endocrine milieu thereby influencing pregnancy outcomes. In a preliminary observation in St. Louis, homeless pregnant women with high behavioral and social risks, when accommodated in a shelter home designed for these women, produced significantly less numbers of premature and low birth weight infants as compared with the general population. Furthermore, in a randomized controlled study in Washington DC, psychobehavioral intervention specifically targeting smoking (primary and secondary), intimate partner violence (IPV), and depression among black pregnant women significantly decreased the rate of miscarriage and low birth weight. These reports may have significant implication to the Japanese situation. Increasing number of Japanese women at reproductive age are exposed to smoking, may have underling psychosocial stress and may suffer from subclinical depression and/or from IPV. Detailed epidemiological studies of women before and during the reproductive age with regard to risk factors can lead to an effective intervention strategy against premature birth in Japan.

Their parents have intense experiences when their babies are in the intensive care unit (ICU, and these have an impact on their thoughts, feelings and relationships, including their relationships with their premature babies. Objectives: The aim of the study was to explore and describe the lived experiences of parents of premature babies in an ICU. Method: Research design was qualitative, exploratory, descriptive and contextual. A purposive sample of parents with premature babies in an ICU in a private hospital in Johannesburg Gauteng in South Africa was used. Eight parents, four mothers and four fathers, married and either Afrikaans or English-speaking, were included in the study. Data were collected by conducting in-depth phenomenological interviews with them and making use of field notes. Trustworthiness was ensured by implementing the strategies of credibility, transferability, dependability and confirmability. Ethical principles such as autonomy, beneficence, nonmaleficence and justice were adhered to throughout the research process. Results: Thematic analyses were utilised to analyse the data. Two themes in the experiences of parents with premature babies in ICU became apparent. Parents experienced thoughts, emotions and hope while their premature babies were in the ICU as well as challenges in their relationships and these challenges influenced their experiences. Recommendations: Mindfulness of intensive care nurses should be facilitated so that intensive care nurses can promote the mental health of parents with premature babies in the ICU. Conclusion: Parents with premature babies in the ICU have thoughts and emotional experiences which include hope and they affect parents’ relationships.

    2016-01-01

    Full Text Available Background. The outcome of neonates with congenital cutaneous Langerhans cell histiocytosis (LCH is variable. Observations. We report a case of LCH in a female premature neonate born at 33-week gestation. She had disseminated cutaneous lesions, which consisted of hemorrhagic papules and vesicles, with sparse healthy skin areas, and the hands and feet were contracted with scarring and blackened. She was in respiratory failure although no apparent pulmonary or bone lesions on X-rays were noted. Skin biopsy confirmed a diagnosis of LCH due to observation of CD1a+ Langerhans cells, which lacked expression of E-cadherin and CD56. The patient died 57 hours after birth. Conclusions. Based on this case and the literature survey, the outcome of premature babies with congenital cutaneous LCH lesions is noted to be unfavorable, with the majority of such cases suffering from multisystem disease.

    Pyridoxine-dependent epilepsy presents early in life, even in utero. It is usually refractory to conventional antiepileptic medications and responds only to lifelong pyridoxine supplementation. Seizures are usually generalized tonic clonic. We report a 3-year-old child that was born prematurely at 25 weeks of gestation. He presented with abnormal movements in the second month of life. At 10 months of age he presented with status epilepticus, which was refractory to multiple antiepileptic medications and was controlled with intravenous pyridoxine. An elevated level of a-aminoadipic semialdehyde excretion in the urine supported the diagnosis of pyridoxine-dependent epilepsy. Subsequently, a c.1195G>C homozygous mutation in the 5q31 aldehyde dehydrogenase 7A1 gene was confirmed. This case calls for considering pyridoxine-dependent epilepsy and its early management in cases with resistant seizures; even in the presence of extreme prematurity with its neurological consequences.

    There are significant delays in implementing vaccination among preterm infants. Description of the frequency and kinds of adverse events following immunization in preterms. Establishment of the group of preterms who will distinctively be susceptible to adverse events. Demographical, clinical data and the occurrence of adverse events after DTaP, HIB and pneumococcal vaccination among preterms during their initial hospitalization were prospectively collected with the use of an electronic data form between 1st June 2011 and 31st May 2015. The analysis was conducted on 138 patients. The groups were divided according to maturity (I: ≤ GA 28w n=73 and GA 29-36 w n=65). There were no statistically significant differences between the groups in the occurrence of adverse events. Out of the total group, following vaccination apnoea developed in 6 newborns (4%) and activity dysfunctions were observed in 13 newborns (10%). The occurrence of apnoea after vaccination positively correlated with the time of non-invasive ventilation and the occurrence of late infection. There were no statistically significant demographical or clinical risk factors for the development of activity dysfunctions following vaccination. Term vaccination in clinically stable preterm infants is a safe medical procedure. However, long-term non-invasive respiratory support and late infections are risk factors for apnea following vaccinations. In these patients vaccinations should be considered during hospitalization.

    2013-03-01

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

    Bovine mastitis is an economic and a welfare problem on dairy farms. The objective of this study was to estimate the costs of clinical mastitis (CM), having a special focus on the cost variation related to culling decisions. A dynamic optimization model was developed to determine an optimal replacement time of a mastitic cow and to estimate the costs of CM, taking into account the risk of premature culling and the uncertainty in CM prevalence. Six lactations were analyzed at monthly periods for Ayrshire and Holstein-Friesian breeds. The estimates reflect Finnish production conditions where mastitis is treated only by veterinarians. Biological parameters of the model were adapted from the literature and the Finnish dairy herd health recording system. Field data were used to produce the risk parameters of culling due to mastitis on commercial dairy farms. The model recommended treating the cows with CM and keeping them in most cases until their fifth lactation. A cheaper (-20%) heifer transferred the optimum to the previous lactation and a more expensive (+20%) heifer to the following lactation. Conditional on optimal replacements, the average cost of CM of an Ayrshire (Holstein-Friesian costs in parentheses) cow was €485 (€458), varying from €209 (€112) to €1,006 (€946). The costs were at the highest when the occurrence of CM was at a top yield phase. In the scenario where the risk of culling due to mastitis was included in the model, the average cost of CM was €596 (€623). Disposing of a young cow at the end of her first lactation month caused the highest costs. The costs converted to figures per cow-year were €121 (€147) with optimal cullings and €155 (€191) in the current Finnish conditions. Thus, the increase in the costs of CM due to premature cullings was 28% (30%.) The main cost sources were long-term production losses regardless of the culling decisions. Premature culling formed 20% (23%) of the total costs. To decrease the costs of

    This study investigates neural language organization in very preterm born children compared to control children and examines the relationship between language organization, age, and language performance. Fifty-six preterms and 38 controls (7-12 y) completed a functional magnetic resonance imaging language task. Lateralization and signal change were computed for language-relevant brain regions. Younger preterms showed a bilateral language network whereas older preterms revealed left-sided language organization. No age-related differences in language organization were observed in controls. Results indicate that preterms maintain atypical bilateral language organization longer than term born controls. This might reflect a delay of neural language organization due to very premature birth.

    The aim of this study was to investigate if individuals born with sub-optimal birth characteristics have reduced probability of reproducing in adulthood. Using population-based registries, the authors included 522 216 males and 494 692 females born between 1973 and 1983 and examined their reproductive status as of 2006. Outcome measure was the hazard ratio (HR) of reproducing. Adjustments were made for socio-economic factors. Males and females born very premature displayed a reduced probability of reproducing [HR = 0.78, 95% confidence interval (CI): 0.70-0.86 for males; HR = 0.81, CI: 0.75-0.88 for females]. Likewise for very low birthweight (HR = 0.83, CI: 0.71-0.95 for males; HR = 0.80, 95% CI: 0.72-0.89 for females). Individuals born large for gestational age (LGA) displayed no significant changes. Males born small for gestational age (SGA) had a 9% lower reproductive rate (CI: 0.89-0.94) and that reduction increased as the individuals aged. Women born SGA tended to start reproducing at an earlier age. The results suggest that being born with low birthweight, premature or SGA (for males) is associated with a reduced probability of reproducing as an adult. LGA shows no statistically significant relationship with future reproduction.

    To determine whether serum fructosamine which is a good marker for detecting hyperglycemia during the previous 2 to 3 wk in infants could predict the development of retinopathy of prematurity in very low birth weight infants. One hundred sixty seven premature infants who had a birth weight of < 1500 g and a gestational age of less than 32 wk were investigated in the present study. Blood glucose was measured at the bedside and infants were recorded as hyperglycemic if their mean blood glucose levels were higher than 150 mg/dL. Serum corrected fructosamine level was obtained from the cord blood at birth and after the first month of life. The infants' eyes were examined by ophthalmologists to detect retinopathy of prematurity at the gestational age of 32 wk or at four wk after birth, whichever came first. Corrected fructosamine was 319.6 ± 59.6 and 272.8 ± 50.6 mmol/l for group 1 on 1(st) and 30(th) day respectively; 320 ± 61.7 and 268.2 ± 47.3 mmol/l for groups 2 + 3 on 1(st) and 30(th) day respectively which did not differ between groups (p = 0.766 and p = 0.665), whereas duration of hyperglycemia was 1.69 ± 1.1 day in group 1 compared with 3.05 ± 2.4 day in groups 2 + 3 which was significantly different (p = 0.019). The multivariate regression analysis indicated that the duration of hyperglycemia in days was significantly correlated with the development of retinopathy of prematurity (OR 3.26; 95% CI 1.09-9.80; p = 0.035). Although the duration of hyperglycemia may contribute to the development of retinopathy of prematurity, serum corrected fructosamine does not have a good predictive value in developing retinopathy of prematurity in very-low-birth-weight (VLBW) infants.

    2002-08-01

    Full Text Available Abstract Background Spontaneous premature ovarian failure presents most commonly with secondary amenorrhea. Young women with the disorder are infertile and experience the symptoms and sequelae of estrogen deficiency. The mechanisms that give rise to spontaneous premature ovarian failure are largely unknown, but many reports suggest a genetic mechanism in some cases. The small family size associated with infertility makes genetic linkage analysis studies extremely difficult. Another approach that has proven successful has been to examine candidate genes based on known genetic phenotypes in other species. Studies in mice have demonstrated that c-kit, a transmembrane tyrosine kinase receptor, plays a critical role in gametogenesis. Here we test the hypothesis that human KIT mutations might be a cause of spontaneous premature ovarian failure. Methods and Results We examined 42 women with spontaneous premature ovarian failure and found partial X monosomy in two of them. In the remaining 40 women with known 46,XX spontaneous premature ovarian failure we evaluated the entire coding region of the KIT gene. We did this using polymerase chain reaction based single-stranded conformational polymorphism analysis and DNA sequencing. We did not identify a single mutation that would alter the amino acid sequence of the c-KIT protein in any of 40 patients (upper 95% confidence limit is 7.2%. We found one silent mutation at codon 798 and two intronic polymorphisms. Conclusion Mutations in the coding regions of the KIT gene appear not to be a common cause of 46,XX spontaneous premature ovarian failure in North American women.

    Cosmology in Eddington-inspired Born-Infeld gravity is investigated using a scalar Born-Infeld field (eg. tachyon condensate) as matter. In this way, both in the gravity and matter sectors we have Born-Infeld-like structures characterised by their actions and via two separate constants, $\\kappa$ and $\\alpha_T^2$ respectively. With a particular choice of the form of $\\dot{\\phi}$ (time derivative of the Born-Infeld scalar), analytical cosmological solutions are found. Thereafter, we explore some of the unique features of the corresponding cosmological spacetimes. For $\\kappa>0$, our solution has a de Sitter-like expansion both at early and late times, with an intermediate deceleration sandwiched between the accelerating phases. On the other hand, when $\\kappa0$ solution, are as good as in $\\Lambda$CDM cosmology. However, the $\\kappa<0$ solution has to be discarded due to the occurrence of a bounce at an unacceptably low redshift.

    In Japan, all 47 prefectures conduct routine air quality monitoring at 1145 stations throughout the country to assess environmental effects. This study aims to provide a better understanding of possible estimations of premature mortality in Japan caused by exposure to monitored and modeled concentrations of tropospheric ozone during the period from January to December, 2005. The spatial distribution and temporal variation of ozone concentrations were modeled using the Models-3 Community Multiscale Air Quality modeling system coupled with the Regional Emission Inventory in Asia (CMAQ/REAS). Premature mortality caused by exposure to ozone was calculated assuming a relative risk (RR) value of 1.003 [95% Confidence Interval (CI): 1.001-1.004] for concentrations above 35 ppb according to the SOMO35 index (annual Sum of daily maximum 8-h Ozone Means Over 35 ppb) recommended by WHO (2008). Based on CMAQ/REAS simulations, the estimated all-cause premature mortality in 2005 is about 13,000 (95% CI: 4320-17,300) cases. This value is 2.5 times greater than the estimated premature mortality based on monitored ozone concentrations, which is 5220 (95% CI: 1740-6960) cases.

  18. Optimal oxygen saturation in premature infants

    2011-09-01

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

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

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

  5. Management of patent ductus arteriosus in premature infants.

    Science.gov (United States)

    Bhat, Rama; Das, Utpala G

    2015-01-01

    Patency of the ductus arteriosus is required for fetal survival in utero. In infants born prematurely, ductus fails to close and shunt reverses from left to right. Incidence of patent ductus arteriosus (PDA) is inversely proportional to the gestational age. A large PDA (>1.5 mm diameter) with left to right shunt in very low birth weight infants can cause pulmonary edema, congestive heart failure, pulmonary hemorrhage and increase the risk for bronchopulmonary dysplasia. Attempts to prevent or close the duct by pharmacological or surgical methods have not changed the morbidity or the long term outcome. Pharmacological treatment with indomethacin or ibuprofen is successful in 75 to 80 % of infants but its use also exposes these infants to undesirable side effects like gastrointestinal bleeding, perforation and necrotizing enterocolitis. Prophylactic therapy with indomethacin or ibuprofen to prevent PDA has not altered the morbidity or long term outcome. Currently, there is a dilemma as to how to treat, when to treat and whom to treat. Recent literature suggests a trial of conservative management during the first week followed by selective use of anti-inflammatory drugs. Surgical ligation is reserved for infants who fail medical therapy and still remain symptomatic. Spontaneous closure of the PDA has been reported in up to 40-67 % of very low birth weight (VLBW) infants by 7 d. In this review authors discuss these controversies and propose a more rational approach.

    To assess language skills in children born preterm and full term by the use of a standardized language test and eye-tracking methods. Children born ≤32 weeks' gestation (n = 44) were matched on sex and socioeconomic status to children born full term (n = 44) and studied longitudinally. The Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III) were administered at 18 months (corrected for prematurity as applicable). The Looking-While-Listening Task (LWL) simultaneously presents 2 pictures and an auditory stimulus that directs the child's attention to one image. The pattern of eye movements reflects visual processing and the efficiency of language comprehension. Children born preterm were evaluated on LWL 3 times between 18 and 24 months. Children born full term were evaluated at ages corresponding to chronological and corrected ages of their preterm match. Results were compared between groups for the BSID-III and 2 LWL measures: accuracy (proportion of time looking at target) and reaction time (latency to shift gaze from distracter to target). Children born preterm had lower BSID-III scores than children born full term. Children born preterm had poorer performance than children born full term on LWL measures for chronological age but similar performance for corrected age. Accuracy and reaction time at 18 months' corrected age displaced preterm-full term group membership as significant predictors of BSID-III scores. Performance and rate of change on language comprehension measures were similar in children born preterm and full term compared at corrected age. Individual variation in language comprehension efficiency was a robust predictor of scores on a standardized language assessment in both groups. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Purpose. The objective of our study was to examine a possible influence of gestational age, birth weight, and Apgar score on amplitudes and latencies of P100 wave in preterm born school-age children. Materials and Methods. We examined the following group of school-age children: 28 with history of prematurity (mean age 10.56 ± 1.66 years and 25 born at term (mean age 11.2 ± 1.94 years. The monocular PVEP was performed in all children. Results. The P100 wave amplitudes and latencies significantly differ between preterm born school-age children and those born at term. There was an essential positive linear correlation of the P100 wave amplitudes with birth weight, gestational age, and Apgar score. There were the negative linear correlations of P100 latencies in 15-minute stimulation from O1 and Oz electrode with Apgar score and O1 and O2 electrode with gestational age. Conclusions. PVEP responses vary in preterm born children in comparison to term. Low birth weight, early gestational age, and poor baseline output seem to be the predicting factors for the developmental rate of a brain function in children with history of prematurity. Further investigations are necessary to determine perinatal factors that can affect the modified visual system function in preterm born children.

    Full Text Available Premature is a newborn alive whose birth weight is equal to or less than 2500 grams, regardless of the duration of gestation. Prematurity have sometimes negative effects on child development by slowing the psychomotor development (child goes to talk later, you can recover delay until the age of 3-5 years. Some of these older children, will be clumsy. PURPOSE: To verify the importance of the adapted recovery program making a correlation between neuro-psychological assessment tests and weight of children born prematurely. HYPOTHESIS: Early systematic and continuous intervention, using adapted physical therapy methods lead to a improved neuromotor development of the premature by reaching the normal range. MATERIAL AND METHODS The study included 10 children, 6 boys and 4 girls, born prematurely. They were subjected to the test "assessment of neuro-psychological development in children 0-36 months" (it is a battery of tests that help to evaluate their development monthly and test weight. Applied therapeutic program included: exercise (performed by the game, massage, neuromotor rehabilitation methods (Bobath, Vojta, Kabat, hydrotherapy and music therapy. RESULTS AND DISCUSSION: If neuro-psychological tests, we proceeded to calculate averages scores for the 3 test, which is further correlated with children's weight. Average scores range between 7 and 10. 333, with an overall average of 9.371. In all 3 tests averages ranging from 8,575 in the initial stage, in 9386, and 10,152 in the midway point in the final stage. CONCLUSIONS: Weight, explain in smaller proportions, and other parameters and results of neuro-psychological tests children (65.6%. ANOVA models indicate statistically significant relationships between parameters and neuro-psychological testing stages, showing progressive improvement of children's performance. Following statistical interpretation can confirm the effectiveness of the recovery program implemented so we suggest to the parents

    2016-01-01

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

    Hypothyroxinemia affects 35-50% of neonates born prematurely (12% of births) and increases their risk of suffering neurodevelopmental alterations. We have developed an animal model to study the role of maternal thyroid hormones (THs) at the end of gestation on offspring's cerebral maturation. Pregnant rats were surgically thyroidectomized at embryonic day (E) 16 and infused with calcitonin and parathormone (late maternal hypothyroidism [LMH] rats). After birth, pups were nursed by normal rats. Pups born to LMH dams, thyroxine treated from E17 to postnatal day (P) 0, were also studied. In developing LMH pups, the cortical lamination was abnormal. At P40, heterotopic neurons were found in the subcortical white matter and in the hippocampal stratum oriens and alveus. The Zn-positive area of the stratum oriens of hippocampal CA3 was decreased by 41.5% showing altered mossy fibers' organization. LMH pups showed delayed learning in parallel to decreased phosphorylated cAMP response element-binding protein (pCREB) and phosphorylated extracellular signal-regulated kinase 1/2 (pERK1/2) expression in the hippocampus. Thyroxine treatment of LMH dams reverted abnormalities. In conclusion, maternal THs are still essential for normal offspring's neurodevelopment even after onset of fetal thyroid function. Our data suggest that thyroxine treatment of premature neonates should be attempted to compensate for the interruption of the maternal supply.

    2012-04-01

    Full Text Available Purpose: To report on 2 cases of aggressive posterior retinopathy of prematurity (ROP treated with intravitreal ranibizumab (Lucentis® and laser photocoagulation. Methods: Two premature females, born at 25 and 26 weeks’ gestation with a birth weight of 530 and 550 g, respectively, with aggressive posterior ROP received combined treatment with laser photocoagulation and intravitreal ranibizumab (0.3 mg [30 µl] to each eye. Structural outcomes were evaluated by indirect ophthalmoscopy and documented by retinography. Results: An intravitreal injection was made at 34 weeks of postmenstrual age in the first case, followed by laser photocoagulation 1 week later. There was a partial regression of ROP with treatment. Five weeks later, neovascularization regrowth with bleeding in both eyes (intraretinal and subhyaloid occurred and retreatment with combined therapy was performed. In the second case, single therapy with laser photocoagulation was made at 34 weeks of postmenstrual age. In spite of the confluent photocoagulation in the avascular area, progression to 4A ROP stage occurred 1 week later. Both eyes were retreated 1 week later with intravitreal ranibizumab and laser photocoagulation. Treatment resulted in ROP regression in both cases. There were no signs of systemic or ocular adverse side effects. Conclusion: The cases presented show that combination therapy of indirect laser photocoagulation and intravitreal ranibizumab can be effective in the management of aggressive posterior ROP. Further investigation on anti-VEGF safety in premature infants is necessary . Additional studies are needed to define the role of anti-VEGF in ROP treatment.

    In a prospective study of 417 premature neonates born before 33 weeks' gestational age, neonatal tracings were reviewed to evaluate the use of EEG in prognosis of neurological injuries. The population was divided into two groups: Group 1, infants who died before the age of 1, and Group 2, survivors in which two categories of motor development were considered. Category A, were abnormal, and Category B, were always normal. Positive rolandic sharp waves (PRSW), which reflect white matter injury, occurred equally in both groups, indicating a similar incidence of white matter damage in Groups 1 and 2. In Group 2, there was a significant correlation of PRSW with developmental motor sequelae (Category A). A frequency of PRSW above 2/min (suggesting more severe periventricular white matter injury) and seizures were significantly more prevalent in Group 1 than in Group 2 and in Category A of Group 2 than in Category B. Background abnormalities occurred equally in both subgroups of extremely premature infants ( 28 weeks' gestation) and extremely (< or = 28 weeks' gestation) premature newborns.

  16. Establishment of the Relationship Between Fathers and Premature Infants in Neonatal Units.

    Parents and their preterm infants (born between 32-37 weeks of gestation) are often overlooked by the healthcare system. And very little attention is given to the relationship parents develop with their infants in the neonatal unit (NNU). Specifically, very few studies focused on fathers and how they establish a relationship with their infants. However, we know that the father-infant relationship is extremely important for their future social development and more. This article presents the results of a qualitative study of the establishment of the father-premature infant relationship in an NNU. The study's theoretical framework was Bell's model of the parent-infant relationship, which encompasses discovery, physical proximity, communication, involvement, and emotional attachment. Ten fathers of premature infants (gestational age: 32-37 weeks) participated in 2 semistructured interviews (1 individual and 1 "in situ," ie, at the infant's bedside) during the first week following the premature birth. The results confirm the emergence of different components of the relationship between fathers and their children from the first days of hospitalization in the NNU. The commitment component is the basis for the development of other components in the relationship with their children. Furthermore, involvement influences the deployment of emotional attachment, discovery, physical proximity, and communication toward premature infants. Similarly, the 5 themes of the model can be seen as forming a dynamic nexus in which each theme influences the others. For neonatal nurses, this model of the early father-child relationship helps the understanding of the deployment of that relationship according to 5 components. Similarly, it provides awareness of the experiences of fathers so that nurses can be better equipped to support and individualize interventions tailored to their specific needs, thus helping them develop and sustain the relationship with their children. This study allows

    The objective of this prospective, randomized clinical trial was to test the hypothesis that there is no difference in the frequency of feeding problems and necrotizing enterocolitis between a group of premature infants who received early enteral feedings while low umbilical artery catheters (LUACs) were in place, and a late group who were not fed until 24 hours after removal of LUACs. Twenty-nine premature infants (born at 28.5 +/- 3.0 SD weeks of gestational age) who were in stable condition received early enteral feedings at a median of 2 days while a LUAC was in place; 31 infants (born at 28.6 +/- 2.7 SD weeks of gestational age) received late enteral feedings at a median of 5 days of age, 24 hours after the removal of the LUAC. Feeding complications and interventions and nutritional characteristics were recorded prospectively. There were no differences in the baseline perinatal characteristics of the two groups. The incidence of gastric residua and the incidence of abdominal distention were the same in both groups. The early feeding group had significantly fewer percutaneous central venous catheters, evaluations for sepsis, and episodes of receiving nothing by mouth while a gastric suction tube was in place. Infants in the early group received parenteral alimentation-lipid emulsion infusions for a median of 13 days versus 30 days for the late-fed group (p = 0.0028 by Wilcoxon test). There were two cases of necrotizing enterocolitis in the early group versus four cases in the late group. Premature infants in stable condition who receive enteral feedings while LUACs are in place do not have an increased incidence of feeding problems compared with infants who do not receive enteral feedings until 24 hours after removal of LUACs.

    We investigate spherically symmetric, static spacetimes in Eddington-inspired Born-Infeld gravity coupled to Born-Infeld electrodynamics. The two constants, $b^2$ and $\\kappa$ which parametrise the Born-Infeld structures in the electrodynamics (matter) and gravity sectors, characterise the features of our analytical solutions. Black holes or naked singularities are found to arise, depending on the values of $b^2$ and $\\kappa$, as well as charge and mass. Several such solutions are classified and understood through the analysis of the associated metric functions. Interestingly, for a particular relation between these two parameters, $b^2=1/{4\\kappa},\\, \\kappa >0$, we obtain a solution resembling the well-known Reissner-Nordstr\\" om line element, albeit some modifications. We study null geodesics and gravitational lensing using this particular solution. Among interesting features we note $(i)$ a decrease in the radius of the photon sphere with increasing $\\kappa$ and $(ii)$ a net negative contribution in the le...

    Premature ovarian failure (POF) is a common condition, affecting approximately 1:100 women. It is characterised by amenorrhea, hypoestrogenism, and elevated gonadotrophin levels in women under the age of 40. It is often an unexpected and distressing diagnosis, which coincides with infertility and menopausal symptoms. There is a well recognised genetic basis to the development of POF. Our laboratory has identified several candidate genes associated with POF.

    2014-01-01

    Progeria is characterized by clinical features that mimic premature ageing. Although the mutation responsible for this syndrome has been deciphered, the mechanism of its action remains elusive. Progeria research has gained momentum particularly in the last two decades because of the possibility of revealing evidences about the ageing process in normal and other pathophysiological conditions. Various experimental models, both in vivo and in vitro, have been developed in an effort to understand...

    The management recommendation for both acquired premature ejaculation (APE) and lifelong PE (LPE) are similar, such as a behavioral/psychotherapy, a pharmacotherapy and a combination of these treatments. For the drug treatment for PE, gold standard is selective serotonin reuptake inhibitors (SSRIs) including dapoxetine or paroxetine. The drug treatment for PE is still developing and some new promising therapeutic options have been proposed. Topical anesthetics, tramadol, and alpha-1 blockers ...

    Preterm birth complication is the leading cause of neonatal death resulting in over one million deaths each year of the 15 million babies born preterm. To accelerate change, we provide an overview of the comprehensive strategy required, the tools available for context-specifi c health system implementation now, and the priorities for research and innovation. There is an urgent need for action on a dual track: (1) through strategic research to advance the prevention of preterm birth and (2) improved implementation and innovation for care of the premature neonate. We highlight evidence-based interventions along the continuum of care, noting gaps in coverage, quality, equity and implications for integration and scale up. Improved metrics are critical for both burden and tracking programmatic change. Linked to the United Nation’s Every Women Every Child strategy, a target was set for 50% reduction in preterm deaths by 2025. Three analyses informed this target: historical change in high income countries, recent progress in best performing countries, and modelling of mortality reduction with high coverage of existing interventions. If universal coverage of selected interventions were to be achieved, then 84% or more than 921,000 preterm neonatal deaths could be prevented annually, with antenatal corticosteroids and Kangaroo Mother Care having the highest impact. Everyone has a role to play in reaching this target including government leaders, professionals, private sector, and of course families who are aff ected the most and whose voices have been critical for change in many of the countries with the most progress.

    Risk of premature birth was evaluated retrospectively in 610 women in the first days after delivery using the prematurity risk score published by Thalhammer 1973. The calculated risk of premature birth was compared than prospectively to postpartal morbidity of the newborn infants as determined by duration of hospital stay, incidence of respiratory distress syndrome, need of artificial ventilation and mortality. A positive correlation could be found between risk of premature birth and postpartal morbidity of the newborn infants especially in small premature infants with birthweights of 2000 grams and less. The same correlation existed also in two groups of infants out of two different obstetric clinics which showed the same distribution of prenatal risks and the same prenatal care frequencies. It clearly becomes evident that infants with the same prenatal risks but good prenatal care during pregnancy had much lower hospital stays, lower respiratory distress frequencies and lower mortality rates than babies delivered from pregnancies badly cared for. These prenatal care related differences in postpartum morbidity again were much more evident in infants out of lower birth weight classes.

    Full Text Available Aim. To find predictive and indicative markers of risk for development of retinopathy of prematurity (ROP and its progression to the stage requiring laser treatment, in premature infants whose gestational age (GA was under 33 weeks. Methods. We retrospectively reviewed medical records of 197 premature infants born in 2005–2010 whose GA<33 weeks and underwent eye screening at Keio University Hospital. The association between candidate risk factors and development or progression of ROP was assessed. Results. Among the 182 eligible infants (median GA, 29.1 weeks; median birth weight (BW, 1028 g, 84 (46% developed any stage of ROP, of which 45 (25% required laser treatment. Multivariate analysis using a stepwise method showed that GA (P=0.002; 95% confidence interval (CI, 0.508–0.858, BW (P<0.001; 95% CI, 0.994–0.998, and lower maternal age (P=0.032; 95% CI, 0.819–0.991 were the risk factors for ROP development and GA (P<0.001; 95% CI, 0.387–0.609 and lower maternal age (P=0.012; 95% CI, 0.795–0.973 were for laser treatment. The odds ratio of requiring laser treatment was 3.3 when the maternal age was <33 years. Conclusion. ROP was more likely to be developed and progressed in infants born from younger mother and low GA.

  6. Delayed early primary visual pathway development in premature infants: high density electrophysiological evidence.

    Directory of Open Access Journals (Sweden)

    Emmanuel Tremblay

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

  7. Long-term impact of preterm birth on exercise capacity in healthy young men: a national population-based cohort study.

    Jenny Svedenkrans

    Full Text Available BACKGROUND: Increasing numbers of survivors of preterm birth are growing into adulthood today. Long-term health-effects of prematurity are still poorly understood, but include increased risk for diabetes, obesity and cardiovascular diseases in adult life. To test if reduced physical fitness may be a link in the causal chain of preterm birth and diseases in later life, the association of preterm birth and adult exercise capacity was investigated. The hypothesis was that preterm birth contributes independently of other risk factors to lower physical fitness in adulthood. METHODS AND FINDINGS: Population-based national cohort study of all males conscripting for military service in 1993-2001 and born in Sweden 1973-1983, n = 218,820. Data were retrieved from the Swedish Conscript Register, the Medical Birth Register and the Population and Housing Census 1990. Primary outcome was the results from maximal exercise test (Wmax in Watt performed at conscription. Association to perinatal and socioeconomic risk factors, other co-variates and confounders were analysed. General linear modelling showed that preterm birth predicted low Wmax in a dose-response related pattern, with 25 Watt reduction in Wmax for the lowest gestational ages, those born ≤27 weeks. Low birth weight for gestational age also independently predicted low Wmax compared to normal and high birth weight (32 Watt reduction for those with a birth weight Standard Deviation Score <2. Low parental education was significantly associated with reduced Wmax (range 17 Watt, as well as both low and high current BMI, with severe obesity resulting in a 16 Watt deficit compared to Wmax top performance. CONCLUSION: Being born preterm as well as being born small for gestational age predicts low exercise capacity in otherwise healthy young men. The effect size of being born preterm equal or exceed that of other known risk factors for unfitness in adults, such as low parental education and overweight.

    The neonatal fate, and outcome at 2 years in a population of 96 premature babies born after no more than 28 weeks of amenorrhea is described. Mortality was directly influenced by the gestational age ( or = 26 WA = 21.1%, p 1,000 g = 20%, p < 0.05). Two other factors with a harmful impact were identified: retarded growth (neonatal mortality doubled) and fetal multiplicity (increased fourfold). Investigation of the neonatal morbidity highlights the importance of respiratory, neurological and digestive problems. Assessment of the longer-term outcome has shown an 11.3 p. cent incidence of handicap. An estimation of the prognosis on the basis of gestational age is proposed.

    In children who are born prematurely or whose birth weight is too low for gestational age (small for gestational age (SGA)) intensive care and follow up are desirable.However, obstacles include the shared care of children born very preterm (care service (and other professionals) and the identification of possible late onset health problems in children born late preterm (32-37 weeks of gestation). This guideline is multidisciplinary and evidence based and is relevant to all professionals involved in the care of this group of children. The main recommendations are: (a) timely and complete transfer of information after discharge from hospital; (b) structured exchange of information in aftercare; (c) assigning a case manager to each child; (d) monitoring growth and development by adjusting age for preterm birth, and (e) using special growth charts for children born preterm to evaluate growth and development.

    The most common behavioural disorder seen in children and adolescents born extremely prematurely is attention deficit hyperactivity disorder (ADHD). The hyperactive/impulsive sub-type of ADHD or the inattentive sub-type or the hyperactive/impulsive/inattentive sub-type can be evident. These sub-types of ADHD can persist into adulthood. The aim of this study was to investigate the relevance of a new immature rat model of repeated hypoxic exposure to these behavioural characteristics of extreme prematurity. More specifically, this study aimed to measure ADHD-like hyperactivity in response to delayed reward, and inattention, in repeated hypoxic versus repeated normoxic rats. Sprague-Dawley rats were exposed to either repeated hypoxia or repeated normoxia during postnatal days (PN) 1-3. The rat brain during PN1-3 is generally considered to be developmentally equivalent to the human brain during extreme prematurity. The rats were then behaviourally tested at 16 months-of-age on a multiple component fixed interval-extinction test. This test detects ADHD-like hyperactivity in response to delayed reward, as well as inattention. It was found that the repeated hypoxic rats exhibited ADHD-like hyperactivity in response to delayed reward, but no attention deficit, when compared to repeated normoxic rats. These findings provide a new animal model to investigate the biological mechanisms and treatment of ADHD-like hyperactivity due to repeated hypoxia during the equivalent of extreme prematurity.

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

    A deterioration of the neuroimmunoendocrine network has been observed in Alzheimer's disease (AD). However, the peripheral immune response has hardly been investigated in this pathology. Since some immune function parameters have been established as good markers of the rate of ageing, and can predict longevity, the aim of the present work was to study some of these functions in splenic leucocytes in transgenic mice for AD of different ages. Young female (4 ± 1 months), adult (9 ± 1 months), and mature (12 ± 1 months) triple-transgenic mice for AD (3 xTgAD) and non-transgenic (NTg) control mice of the same ages were used. The chemotaxis, the anti-tumour activity of « natural killer » (NK) cells and the lymphoproliferative response in the presence of the mitogens concanavalin A and lipopolysaccharide, functions that decrease with age, were determined in splenic leucocytes. In addition, the differences in lifespan between 3 xTgAD and NTg were studied in parallel using other animals, until their death through natural causes. In 3 xTgAD, with respect to NTg, chemotaxis decreased at all ages studied, whereas in lymphoproliferative response this reduction was shown at 4 months and 9 months. NK activity was diminished only in young 3 xTgAD with respect to NTg. The 3 xTgAD showed a shorter lifespan than the NTg control group. The 3 xTgAD mice show a premature immunosenescence, which could explain their early mortality. The determination of these immune functions at peripheral level could serve as a marker of the progression of the Alzheimer's disease. Copyright © 2013 SEGG. Published by Elsevier Espana.

    Preterm birth (PTB), defined as birth at a gestational age (GA) of less than 37 weeks, is associated with increased hospital costs. Lower GA at birth is negatively correlated with the presence of neonatal comorbidities, further increasing costs. This study evaluated incremental costs associated with comorbidities of PTB following spontaneous labor at 24-36 weeks. Birth records from January 2001 to December 2010 at the Medical University of South Carolina were screened to identify infants born at GA 23-37 weeks after uncomplicated singleton pregnancies and surviving to discharge. Comorbidities of interest and incremental costs were analyzed with a partial least squares (PLS) regression model adjusted for comorbidities and GA. Incremental comorbidity-associated costs, as well as total costs, were estimated for infants of GA 24-36 weeks. A total of 4,292 delivery visit records were analyzed. Use of the PLS regression model eliminated issues of multicollinearity and allowed derivation of stable cost estimates. Incremental costs of comorbidities at a mean GA of 34 weeks ranged from $4,529 to $23,121, and exceeded $9,000 in 6 cases. Incremental costs rangedfrom a high of $41,161 for a GA 24-week infant with a comorbidity of retinopathy of prematurity requiring surgery (ROP4) to $3,683 for a GA 36-week infant with a comorbidity of convulsions. Incremental comorbidity costs are additive, so the costs for infants with multiple comorbidities could easily exceed the high of $41,161 seen with ROP4. The PLS regression model allowed derivation of stable cost estimates from multivariate and highly collinear data and can be used in future cost analyses. Using this data set, predicted costs of all comorbidities, as well as total costs, negatively correlated with GA at birth.

    Premature menopause affects 1% of women under the age of 40, the usual age of the menopause is 51. Most women will present with irregular periods or no periods at all with or without climacteric symptoms. Around 10% of women present with primary amenorrhoea. A careful history and examination are required. It is important to ask specifically about previous chemotherapy or radiotherapy and to look for signs of androgen excess e.g. polycystic ovarian syndrome, adrenal problems e.g. galactorrhoea and thyroid goitres. Once pregnancy has been excluded, a progestagen challenge test can be performed in primary care. Norethisterone 5 mg tds po for ten days or alternatively medroxyprogesterone acetate 10 mg daily for ten days is prescribed. A withdrawal bleed within a few days of stopping the norethisterone indicates the presence of oestrogen and bleeding more than a few drops is considered a positive withdrawal bleed. The absence of a bleed indicates low levels of oestrogen, putting the woman at risk of CVD and osteoporosis. FSH levels above 30 IU/l are an indicator that the ovaries are failing and the menopause is approaching or has occurred. It should be remembered that FSH levels fluctuate during the month and from one month to the next, so a minimum of two measurements should be made at least four to six weeks apart. The presence of a bleed should not exclude premature menopause as part of the differential diagnosis as there can be varying and unpredictable ovarian function remaining. The progestagen challenge test should not be used alone, but in conjunction with FSH, LH and oestradiol. There is no treatment for premature menopause. Women desiring pregnancy should be referred to a fertility clinic and discussion of egg donation. Women not wishing to become pregnant should be prescribed HRT until the age of 50 to control symptoms of oestrogen deficiency and reduce the risks of osteoporosis and CVD.

    2016-08-01

    For many decades it has been thought that lifelong premature ejaculation (PE) is only characterized by persistent early ejaculations. Despite enormous progress of in vivo animal research, and neurobiological, genetic and pharmacological research in men with lifelong PE, our current understanding of the mechanisms behind early ejaculations is far from complete. The new classification of PE into four PE subtypes has shown that the symptomatology of lifelong PE strongly differs from acquired PE, subjective PE and variable PE. The phenotype of lifelong PE and therefore also the pathophysiology of lifelong PE is much more complex. A substantial number of men with lifelong PE not only have PE, but also premature erection and premature penile detumescence as part of an acute hypertonic or hypererotic state when engaged in an erotic situation or when making love. As both erectio praecox, ejaculatio praecox, detumescentia praecox, and the hypererotic state are part of the phenotype lifelong PE, it is argued that lifelong PE is not only a disturbance of the timing of ejaculation but also a disturbance of the timing of erection, detumescence and arousal. Since 1998, the pathophysiology of lifelong PE was thought to be mainly mediated by the central serotonergic system in line with genetic polymorphisms of specific serotonergic genes. However, by accepting that lifelong PE is characterized by the reversible hypertonic state the hypothesis of mainly serotonergic dysfunction is no longer tenable. Instead, it has been postulated that the pathophysiology of lifelong PE is mediated by a very complex interplay of central and peripheral serotonergic, dopaminergic, oxytocinergic, endocrinological, genetic and probably also epigenetic factors. Progress in research of lifelong PE can only be accomplished when a stopwatch is used to measure the IELT and the cut-off point of 1 minute for the definition of lifelong PE is maintained.

    Full Text Available Premature ovarian failure (POF affects 1% of young women. This condition has significantpsychological sequelae and major health implications. POF seriously interferes with fertility andfamily planning. Diverse etiologies are associated with POF.Literature review related to the causes and pathogenesis of POF, cited between the year 1900 andMay 2010.POF may be either spontaneous or induced. The known causes include:- Genetic disorders, which could involve the X chromosome or autosomes. However, the growingbody of literature demonstrates a list of newly discovered mutations that may be responsible forcausing POF. Most of these mutations are extremely rare, and most cases of POF are still consideredto be idiopathic.- Autoimmune causes; there is some evidence of an association of POF with lymphocytic oophoritisand other autoimmune disorders. Antiovarian antibodies are reported in POF, but their specificityand pathogenic role are obscure.- Iatrogenic causes; chemotherapy, radiotherapy and pelvic surgery can lead to POF.- Infectious Causes; some viral and microbial infections can be followed by POF.- Environmental toxins, such as cigarette smoking are reported as risk factors of spontaneous POF.- Idiopathic; in most cases, no identifiable etiology can be recognized after complete evaluation.

    Premature ovarian failure (POF), a serious life-changing condition that affects young women, remains an enigma and the researchers' challenge. The term POF generally describes a syndrome of gonadal failure before the age of 40, characterized by amenorrhea, sex steroid deficiency and elevated levels of gonadotropins. Infertility and psychological stress are common consequences of this entity the prevalence of which is 0.9-3%. The known cause of this condition includes: genetic aberrations, autoimmune ovarian damage, iatrogenic and environmental factors, although in majority of cases the underlying cause is not identified. For many women in whom the cause of ovarian failure is unknown, autoimmunity may be the pathogenic mechanism. There is currently evidence that some cases of POF are due to faulty recognition of self in the ovary by the immune system, possibly provoked by genetic or environmental factors initiating such immune response. Numerous evidence, including association with multiple autoimmune endocrine disorders, clinical reversibility, transitory estrogen deficiency, histological and immunological features and the demonstration of circulating ovarian antibodies in serum samples from women with POF, have suggested its immunological origin. We discuss the possible role of such an autoimmune process as a cause or consequence of POF including treatment strategies in POF patients.

    This is a thorough investigation into contemporary young people and their media life. The article conceptualizes a typology of media life, drawing on a theoretical body involving the sociology of generations, life course research, media life and individualization. This empirically derived typology...... makes a strong instrument for an understanding of the media life of the young, furnishing insights into how they have constructed their use of media. The investigation is based on a robust national survey with Swedes born 1994–2001, conducted in 2010, and focusing on four media: television, gaming......, the Internet and mobile devices. Two of the findings are particularly surprising. Firstly, the results reveal that the young generally lead heterogeneous media lives, varying with age and sex. Secondly, although some young people literarily live their life in media, there are also de facto young who live...

For the drug treatment for PE, gold standard is selective serotonin reuptake inhibitors (SSRIs) including dapoxetine or paroxetine. The drug treatment for PE is still developing and some new promising therapeutic options have been proposed. Topical anesthetics, tramadol, and alpha-1 blockers will be the next strategies of the drug treatment for PE in the future.

    Premature ejaculation (PE) is recognized to be the most common male sexual disorder. PE provides difficulties for professionals who treat this condition because there is neither a universally accepted definition nor a medication approved by the Food and Drug Administration (FDA). Despite these shortcomings, physicians continue to diagnose their patients with PE according to major guidelines and treat them with either behavioral therapies or off-label medications. This review focuses on current and emerging treatment options and medications for PE. Advantages and limitations of each treatment option are discussed in the light of current published peer-reviewed literature.

    Full Text Available Being born with nonoptimal birth characteristics decreases the chance of becoming a father. Urogenital malformations as well as metabolic syndrome are more common in men born small for gestational age (SGA and could be contributing factors to the reduced fertility rate seen in these men. It could imply that men becoming fathers by assisted reproductive technology (ART more often are born with low birth weight (LBW, preterm, and/or SGA than men conceiving without treatment and also that men where intracytoplasmic sperm injection (ICSI had to be performed more often are born with nonoptimal birth characteristics than men where conventional in vitro fertilization (IVF successfully could be used. In this retrospective, case-control study using Swedish national registers, we compared the birth characteristics of 1206 men who have become fathers by ART with a control group consisting of age-matched men who became fathers without treatment. The differences in birth characteristics between men becoming fathers by IVF and ICSI were also assessed. For men becoming fathers by ART, OR of being born with LBW was 1.66 (95% CI = 1.17-2.36 compared with fathers who conceived without treatment. OR of being born prematurely was 1.32 (95% CI = 1.00-1.77. Men becoming fathers via ICSI had a doubled increased likelihood of being born SGA compared with men who became fathers via IVF (OR = 2.12; 95% CI = 1.17-3.83. In conclusion, we have found that men becoming fathers by ICSI treatments had more often been born SGA than men becoming fathers by conventional IVF.

    Massage therapy has been used in the care of premature infants for many years in western countries, and a significant body of research has already shown the effectiveness of massage therapy in significantly increasing body weight, decreasing infant hospital durations, enhancing bone formation, and improving behavior. Key considerations when applying massage therapy on premature infants include gestational age, bodyweight, and physical condition. Nurses can teach parents to administer massage therapy on their premature infants to enhance parent-child attachment and interaction. This article introduces massage therapy principles and methods, the effectiveness of massage therapy in premature infant care, and an approach to teaching parents how to apply massage therapy on their premature infants. Massage therapy can be included in premature infant care programs in the future.

    Premature infants are thought to be at increased risk for developmental disorders. We evaluated facial recognition by premature infants during early infancy, as this ability has been reported to be impaired commonly in developmentally disabled children. In premature infants and full-term infants at the age of 4 months (4 corrected months for premature infants), visual behaviors while performing facial recognition tasks were determined and analyzed using an eye-tracking system (Tobii T60 manufactured by Tobii Technologics, Sweden). Both types of infants had a preference towards normal facial expressions; however, no preference towards the upper face was observed in premature infants. Our study suggests that facial recognition ability in premature infants may develop differently from that in full-term infants.

    Full Text Available The problem of intestinal microbiota influencing the health of early aged children has become especially relevant over the past few years. On one hand, this is due to the significant worsening of the human environment ecology, on the other — due to the high prevalence of digestive disorders in children, especially premature ones. The introduction of modern high-informative molecular-genetic research methods (PCR-amplification with gene sequenation made it possible to reveal the primary stage of human colonization by bacteria even at the stage of fetal ontogenesis and to thoroughly decode the microbiota structure in newborns and first-year babies. It is established, that the mothers microbiota has a direct effect on the quantity and quality of the child’s microbiota. The mother’s microbiota depends not only on her possessing inflammatory, but also metabolic diseases (obesity. There is also a direct correlation between the children’s microbiota and the wway they were born (microbiota is better in cases of natural birth, and these differences are prevalent after a number of months after birth. One of the main factors affecting microbiota after birth from the very first day is nutrition. Most studies earnestly confirm the role of breastfeeding in contributing to an optimal microbiocenosis in the child. Antibacterial therapy, being received by either the mother or the child has a negative effect on the colonization of the intestines by symbiont microbes. The negative impacts on the micro flora are especially significant for premature children especially those born with a very low and extremely low body mass. The ontogenesis of these children is most severed by malicious factors (infections followed by the necessity of a massive antibacterial therapy, hypoxia, surgical birth, forced artificial feeding in connection with a general immaturity, including not yet fully-fledged body defense systems.

    Most of our current understanding of the neurobiology of sexual behavior and ejaculatory function has been derived from animal studies using rats with normal sexual behaviour. However, none of these proposed models adequately represents human ejaculatory disorders. Based on the "ejaculation distribution theory", which postulates that the intravaginal ejaculation latency time in men is represented by a biological continuum, we have developed an animal model for the research of premature and delayed ejaculation. In this model, a large number of male Wistar rats are investigated during 4-6 weekly sexual behavioural tests. Based on the number of ejaculations during 30 min tests, rapid and sluggish ejaculating rats are distinguished, each representing approximately 10% at both ends of a Gaussian distribution. Together with other parameters, such as ejaculation latency time, these rats at either side of the spectrum resemble men with premature and delayed ejaculation, respectively. Comparable to the human situation, in a normal population of rats, endophenotypes exist with regard to basal sexual (ejaculatory) performance.

    Nazar, N

    This work is the product of the checking of the pathogenesis, incidence, treatment, and prognostic of the intraventricular hemorrhage in the premature newborn. In the revised publications, that include important series of following, this pathology is present in 25% of the infants weighing less than 1,500 g, in which the mortality and morbidity is greater than that of normal newborns, since the development of intraventricular hemorrhage can produce alterations of cerebral blood flow in the immature germinal matrix and in the microvascular net. In consequence the prevention of the intraventricular hemorrhage is directly related with its pathogenesis. It is said that the use of dexamethasone steroids in low doses in the prenatal period, and low doses of indomethacin in the postnatal period, can give better neuroprotection. The surgical treatment is exceptional and has very precise indications, when a progresive hydrocephalus of later apparition is proven. Therefore in premature newborns with intraventricular hemorrhage the best actual treatment is to use an appropiate pharmacological and medical following

    The second Ad Hoc International Society for Sexual Medicine (ISSM) Committee for the Definition of Premature Ejaculation defined acquired premature ejaculation (PE) as a male sexual dysfunction characterized by a the development of a clinically significant and bothersome reduction in ejaculation latency time in men with previous normal ejaculatory experiences, often to about 3 minutes or less, the inability to delay ejaculation on all or nearly all vaginal penetrations, and the presence of negative personal consequences, such as distress, bother, frustration and/or the avoidance of sexual intimacy. The literature contains a diverse range of biological and psychological etiological theories. Acquired PE is commonly due to sexual performance anxiety, psychological or relationship problems, erectile dysfunction (ED), and occasionally prostatitis and hyperthyroidism, consistent with the predominant organic etiology of acquired PE, men with this complaint are usually older, have a higher mean BMI and a greater incidence of comorbid disease including hypertension, sexual desire disorder, diabetes mellitus, chronic prostatitis, and ED compared to lifelong, variable and subjective PE.

    1998-01-01

    Full Text Available This report deals with our experience in the management of threshold retinopathy of prematurity (ROP. A total of 45 eyes of 23 infants were subjected to treatment of threshold ROP. 26.1% of these infants had a birth weight of >l,500 gm. The preferred modality of treatment was laser indirect photocoagulation, which was facilitated by scleral depression. Cryopexy was done in cases with nondilating pupils or medial haze and was always under general anaesthesia. Retreatment with either modality was needed in 42.2% eyes; in this the skip areas were covered. Total regression of diseases was achieved in 91.1% eyes with no sequelae. All the 4 eyes that progressed to stage 5 despite treatment had zone 1 disease. Major treatment-induced complications did not occur in this series. This study underscores the importance of routine screening of infants upto 2,000 gm birth weight for ROP and the excellent response that is achieved with laser photocoagulation in inducing regression of threshold ROP. Laser is the preferred method of treatment in view of the absence of treatment-related morbidity to the premature infants.

    2009-08-07

    Parasitic food-borne diseases are generally underrecognised, however they are becoming more common. Globalization of the food supply, increased international travel, increase of the population of highly susceptible persons, change in culinary habits, but also improved diagnostic tools and communication are some factors associated with the increased diagnosis of food-borne parasitic diseases worldwide. This paper reviews the most important emerging food-borne parasites, with emphasis on transmission routes. In a first part, waterborne parasites transmitted by contaminated food such as Cyclospora cayetanensis, Cryptosporidium and Giardia are discussed. Also human fasciolosis, of which the importance has only been recognised in the last decades, with total numbers of reported cases increasing from less than 3000 to 17 million, is looked at. Furthermore, fasciolopsiosis, an intestinal trematode of humans and pigs belongs to the waterborne parasites as well. A few parasites that may be transmitted through faecal contamination of foods and that have received renewed attention, such as Toxoplasma gondii, or that are (re-)emerging, such as Trypanosoma cruzi and Echinococcus spp., are briefly reviewed. In a second part, meat-borne parasite infections are reviewed. Humans get infected by eating raw or undercooked meat infected with cyst stages of these parasites. Meat inspection is the principal method applied in the control of Taenia spp. and Trichinella spp. However, it is often not very sensitive, frequently not practised, and not done for T. gondii and Sarcocystis spp. Meat of reptiles, amphibians and fish can be infected with a variety of parasites, including trematodes (Opisthorchis spp., Clonorchis sinensis, minute intestinal flukes), cestodes (Diphyllobothrium spp., Spirometra), nematodes (Gnathostoma, spp., anisakine parasites), and pentastomids that can cause zoonotic infections in humans when consumed raw or not properly cooked.

    Hami is a 3-year-old boy who is a former premature 25-week infant with a birth weight of 1 pound 9 ounces. He had a relatively smooth Neonatal Intensive Care Unit (NICU) course; he required intubation for 1 month and went home on room air. He had a left Grade I intraventricular hemorrhage that was resolved by 2 months of life. He had 7 blood transfusions for anemia over the first 3 months of life. A brainstem auditory evoked potential test was normal at hospital discharge, and he showed no evidence of retinopathy of prematurity. He never had seizure activity.He was discharged to home at 3 months where he did well and thrived on a high calorie formula. He walked at 17 months and spoke his first words at 2 years. He was enrolled in Early Intervention at the time of discharge from hospital; monthly home visits were increased to weekly visits by an early childhood educator at 12 months. When he was 12 months, he was enrolled in a family day care with 4 other children younger than 3 years. Hami's language development was slow; at 2.5 years of age, he was beginning to make 2 word combinations. Early intervention services were increased to include an additional hour of speech and language therapy as well as a play group.Hami's mother is 33 years old, and this is her first child. She worked as an accounting assistant, but she was able to be home with Hami for the first year of his life. She returned to full-time work on his first birthday. Hami's father is 35 years old and works for the national electrical grid as a manager. They are not married but have lived together for the last 5 years. Dad works evenings and cares for Hami from 4 to 6 pm after childcare; mom returns from work at 6 pm. Dad leaves for work at 7 pm and works till 2 am. Their relationship has been strained by the child care demands, their work schedules, and Hami's developmental progress.Hami's primary care pediatrician specializes in children with complex medical problems.

  18. Born Reciprocity and Cosmic Accelerations

    CERN Document Server

    Bolognesi, S

    2015-01-01

    The trans-Planckian theory is a model that realizes concretely the Born reciprocity idea, which is the postulate of absolute equivalence between coordinate $x$ and momenta $p$. This model is intrinsically global, and thus it is naturally implemented in a cosmological setting. Cosmology and Born reciprocity are made for each other. Inflation provides the essential mechanism to suppress the terms coming from the dual part of the action. The trans-Planckian theory, on the other hand, provides an explanation for the accelerated periods of the universe scale factor, both the inflationary period and the present period dominated by dark energy. All of this is possible just considering a simple model that contains gravity, one gauge field plus one matter field (to be identified with dark matter) together with the reciprocity principle.

    The aim of this review was to identify the underlying relationship between preterm birth and the development of cardiovascular diseases. Preterm birth significantly affects the elastin content and viscoelastic properties of the vascular extracellular matrix in human arteries. Inadequate elastin synthesis during early development may cause a permanent increase in arterial stiffness in adulthood. Early and permanent alterations in viscoelastic properties may lead to hypertension and cardiovascular disease development in adults born prematurely. ©2014 Foundation Acta Paediatrica.

    The NR5A1 gene encodes for steroidogenic factor 1, a nuclear receptor that regulates proper adrenal and gonadal development and function. Mutations identified by NR5A1 sequencing have been associated with disorders of sex development (DSD), ranging from sex reversal to severe hypospadias in 46,XY patients and premature ovarian failure (POF) in 46,XX patients. Previous reports have identified four families with a history of both 46,XY DSD and 46,XX POF carrying segregating NR5A1 sequence mutations. Recently, three 46,XY DSD sporadic cases with NR5A1 microdeletions have been reported. Here, we identify the first NR5A1 microdeletion transmitted in a pedigree with both 46,XY DSD and 46,XX POF. A 46,XY individual with DSD due to gonadal dysgenesis was born to a young mother who developed POF. Array CGH analysis revealed a maternally inherited 0.23 Mb microdeletion of chromosome 9q33.3, including the NR5A1 gene. Based on this finding, we screened patients with unexplained 46,XY DSD (n = 11), proximal hypospadias (n = 21) and 46,XX POF (n = 36) for possible NR5A1 copy-number variations (CNVs) via multiplex ligation-dependent probe amplification (MLPA), but did not identify any additional CNVs involving NR5A1. These data suggest that NR5A1 CNVs are an infrequent cause of these disorders but that array CGH and MLPA are useful genomic screening tools to uncover the genetic basis of such unexplained cases. This case is the first report of a familial NR5A1 CNV transmitting in a pedigree, causing both the male and female phenotypes associated with NR5A1 mutations, and the first report of a NR5A1 CNV associated with POF.

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

    2017-07-01

    Background Familial hypercholesterolemia is a common autosomal dominant disease, caused by mutations leading to elevated low-density lipoprotein (LDL) cholesterol and, if untreated, to premature cardiovascular disease. Methods Patients (young adults with a family history of hypercholesterolaemia or premature cardiovascular disease) with LDL cholesterol concentration ≥4.9 mmol/l, after excluding Familial Combined Hyperlipidaemia, were evaluated for causative mutations, Dutch Lipid Clinic Network score calculation and non-invasive ultrasound examination of carotid arteries. Results Of the 263 patients, 210 were heterozygotes for LDL receptor ( LDLR) mutations, four had APOB gene mutations, one PCSK9 gene mutation, while 48 had no evidence of mutations. Among 194 unrelated index cases 149 had mutations (77%). Among patients with LDLR mutations ( n = 145), there were five compound heterozygotes, 75 patients with null mutations and 65 with missense mutations. As many as 178 patients underwent a follow-up and treatment (statin ± ezetimibe), achieving a mean reduction of 49% in LDL cholesterol, with 21% of patients reaching the LDL goal of 2.6 mmol/l. In a multivariate analysis, carotid plaques, at ultrasound examination, were associated with the presence of genetic mutation ( p = 0.001), LDL cholesterol ( p pressure. The presence of carotid plaque ( p = 0.017), LDL cholesterol ( p < 0.003), Dutch Lipid Clinic Network score ( p < 0.001) were independently associated with premature cardiovascular disease. Conclusions We identified patients with causative mutations in 82% of the cases under study. In addition to LDL cholesterol and Dutch Lipid Clinic Network score, carotid plaques in ultrasound evaluation provide direct evidence of premature vascular disease and are associated with high risk for cardiovascular events.

    Brain ultrasonography plays a central role in the detection and management of neonatal disease in the preterm infant. Although morphological study, using high-frequency transducers, remains the cornerstone of imaging, pulsed and colour Doppler scans provide additional information and improve the diagnostic and prognostic accuracy of ultrasonography. Particular features of normal brain US in the extremely preterm infant are reported. Cerebral haemorrhage and its different patterns (intraventricular haemorrhage and periventricular hemorrhagic infarction) are described. The value of Doppler techniques is emphasized, e.g. demonstration of coloured signal within the aqueduct of Sylvius, visualization of patency of the terminal veins, demonstration of Doppler spectrum fluctuations, recognition of low blood flow, and the detection of vasodilatation. The sonographic diagnosis of periventricular leucomalacia and its difficulties are documented. Some uncommon brain lesions of the premature infant are illustrated, e.g. gangliothalamic ischaemic damage, cortical necrosis, focal infarcts, etc. The importance of repeating the US examinations until near term is highlighted.

    2009-01-01

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

    Full Text Available Gastric pneumatosis is extremely rare during infancy. It has been reported in association with necrotizing enterocolitis or congenital abnormalities such as pyloric stenosis. Here, we report a case of gastric pneumatosis in a premature neonate on synchronized nasal intermittent positive pressure ventilation. No pneumatosis was noted in the rest of the bowel or esophagus. There could have been mild damage in the gastric mucosa, either related to the placement of the feeding tube or secondary to the use of indomethacin or both. The condition was further aggravated by noninvasive ventilation. An increase in intragastric pressure resulted in the submucosal dissection of air followed by the development of gastric pneumatosis. Conservative management strategies, including the use of a nasogastric tube for decompression and the withholding of feeding, successfully managed the gastric pneumatosis in our patient. An uneventful recovery was made after conservative management. Prompt recognition and evaluation of this condition were essential for making the diagnosis.

    2016-08-01

    Premature ejaculation (PE) is a poorly understood condition and is considered as the most common sexual disorder in men. The ambiguity surrounding PE is in part due to the difficulty in conducting and interpreting research in the absence of a standardised definition that adequately encompasses the characteristics of these patients. An enhanced awareness of sexual dysfunctions in the recent decades has lead to an increase in scientific research that has challenged the traditional paradigm regarding PE. This has also enabled to establish a universal definition and classification of the disease. A move to a more evidence based approach has improved the clinicians' ability to define those who need medical treatment, as well as perform further research in this complex condition.

  9. Bmi-1 absence causes premature brain degeneration.

    Directory of Open Access Journals (Sweden)

    Guangliang Cao

    Full Text Available Bmi-1, a polycomb transcriptional repressor, is implicated in cell cycle regulation and cell senescence. Its absence results in generalized astrogliosis and epilepsy during the postnatal development, but the underlying mechanisms are poorly understood. Here, we demonstrate the occurrence of oxidative stress in the brain of four-week-old Bmi-1 null mice. The mice showed various hallmarks of neurodegeneration including synaptic loss, axonal demyelination, reactive gliosis and brain mitochondrial damage. Moreover, astroglial glutamate transporters and glutamine synthetase decreased in the Bmi-1 null hippocampus, which might contribute to the sporadic epileptic-like seizures in these mice. These results indicate that Bmi-1 is required for maintaining endogenous antioxidant defenses in the brain, and its absence subsequently causes premature brain degeneration.

  10. Periodic heart rate decelerations in premature infants.

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

  11. Enteral nutrition of the premature infant

    Full Text Available Early nutritional support for preterm infants is critical because such support influences long-term outcome. Minimal enteral feeding should be initiated as soon as possible if an infant is stable and if feeding advancement is recommended as relevant to the clinical course. Maternal milk is the gold standard for enteral feeding, but fortification may be needed to achieve optimal growth in a rapidly growing premature infant. Erythromycin may aid in promoting gastrointestinal motility in cases that exhibit feeding intolerance. Selected preterm infants need vitamins, mineral supplements, and calorie enhancers to meet their nutritional needs. Despite all that is known about this topic, additional research is needed to guide postdischarge nutrition of preterm infants in order to maintain optimal growth and neurodevelopment.

  12. Premature and accelerated ageing: HIV or HAART?

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Highly Active Anti-Retroviral Therapy (HAART has significantly increased life expectancy of the HIV-positive population. Nevertheless, the average lifespan of HIV patients remains shorter compared to uninfected individuals. Immunosenescence, a current explanation for this difference invokes heavily on viral stimulus despite HAART efficiency in viral suppression. We propose here that the premature and accelerated ageing of HIV patients can also be caused by adverse effects of antiretroviral drugs, specifically those that affect the mitochondria. The Nucleoside Reverse Transcriptase Inhibitor (NRTI antiretroviral drug class for instance, is known to cause depletion of mitochondrial DNA via inhibition of the mitochondrial specific DNA polymerase-ƴ. Besides NRTIs, other antiretroviral drug classes such as Protease Inhibitors also cause severe mitochondrial damage by increasing oxidative stress and diminishing mitochondrial function. We also discuss important areas for future research and argue in favour of the use of C. elegans as a novel model system for studying these effects.

  13. Mechanical ventilation of the premature neonate.

    2011-09-01

    Although the trend in the neonatal intensive care unit is to use noninvasive ventilation whenever possible, invasive ventilation is still often necessary for supporting pre-term neonates with lung disease. Many different ventilation modes and ventilation strategies are available to assist with the optimization of mechanical ventilation and prevention of ventilator-induced lung injury. Patient-triggered ventilation is favored over machine-triggered forms of invasive ventilation for improving gas exchange and patient-ventilator interaction. However, no studies have shown that patient-triggered ventilation improves mortality or morbidity in premature neonates. A promising new form of patient-triggered ventilation, neurally adjusted ventilatory assist (NAVA), was recently FDA approved for invasive and noninvasive ventilation. Clinical trials are underway to evaluate outcomes in neonates who receive NAVA. New evidence suggests that volume-targeted ventilation modes (ie, volume control or pressure control with adaptive targeting) may provide better lung protection than traditional pressure control modes. Several volume-targeted modes that provide accurate tidal volume delivery in the face of a large endotracheal tube leak were recently introduced to the clinical setting. There is ongoing debate about whether neonates should be managed invasively with high-frequency ventilation or conventional ventilation at birth. The majority of clinical trials performed to date have compared high-frequency ventilation to pressure control modes. Future trials with premature neonates should compare high-frequency ventilation to conventional ventilation with volume-targeted modes. Over the last decade many new promising approaches to lung-protective ventilation have evolved. The key to protecting the neonatal lung during mechanical ventilation is optimizing lung volume and limiting excessive lung expansion, by applying appropriate PEEP and using shorter inspiratory time, smaller tidal

    Delayed umbilical cord clamping is reported to increase neonatal blood volume. We estimated the clinical outcomes in premature neonates who had delayed umbilical cord clamping compared with a similar group who had early umbilical cord clamping. This was a before-after investigation comparing early umbilical cord clamping with delayed umbilical cord clamping (45 seconds) in two groups of singleton neonates, very low birth weight (VLBW) (401-1,500 g) and low birth weight (LBW) (greater than 1,500 g but less than 35 weeks gestation). Neonates were excluded from delayed umbilical cord clamping if they needed immediate major resuscitation. Primary outcomes were provision of delivery room resuscitation, hematocrit, red cell transfusions, and the principle Vermont Oxford Network outcomes. In VLBW neonates (77 delayed umbilical cord clamping, birth weight [mean±standard deviation] 1,099±266 g; 77 early umbilical cord clamping 1,058±289 g), delayed umbilical cord clamping was associated with less delivery room resuscitation, higher Apgar scores at 1 minute, and higher hematocrit. Delayed umbilical cord clamping was not associated with significant differences in the overall transfusion rate, peak bilirubin, any of the principle Vermont Oxford Network outcomes, or mortality. In LBW neonates (172 delayed umbilical cord clamping, birth weight [mean±standard deviation] 2,159±384 g; 172 early umbilical cord clamping 2,203±447 g), delayed umbilical cord clamping was associated with higher hematocrit and was not associated with a change in delivery room resuscitation or Apgar scores or with changes in the transfusion rate or peak bilirubin. Regression analysis showed increasing gestational age and birth weight and delayed umbilical cord clamping were the best predictors of higher hematocrit and less delivery room resuscitation. Delayed umbilical cord clamping can safely be performed in singleton premature neonates and is associated with a higher hematocrit, less delivery room

    The Born Approximation is a fundamental formula in Physics, it allows the calculation of weak scattering via the Fourier transform of the scattering potential. I extend the Born Approximation by including in the formula the Fourier transform of a truncated basis of the infinite number of appropriately normalised resonant states. This extension of the Born Approximation is named the Resonant-State Expansion Born Approximation or RSE Born Approximation. The resonant-states of the system can be calculated using the recently discovered RSE perturbation theory for electrodynamics and normalised correctly to appear in spectral Green's functions via the flux volume normalisation.

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

    1997-01-01

    The identification and characteristics of premature convergence in genetic algorithms (GAs) are investigated Through a detailed quantitative analysis on the search capability and the degree of population diversity, the cause of premature convergence in GAs is recognized, and attributed to the maturation effect of the GAs: The minimum schema deduced from current population, which is the largest search space of a GA, converges to a homogeneous population in probability 1 ( so the search capability of the GA decreases and premature convergence occurs). It is shown that, as quantitative features of the maturation effect, the degree of population diversity converges to zero with probability 1, and the tendency for premature convergence is inversely proportional to the population size and directly proportional to the variance of the fitness ratio of zero allele at any gene position of the current population. Based on the theoretical analysis, several strategies for preventing premature convergence are suggest

    The studies on the aetiological factors of a premature delivery constitute an old fear of obstetricians and epidemiologists. However, they remain confused and the very definition of prematurity is among the first sources of confusion. There are many therapeutic methods considered as preventive. Their efficacy is debatable whilst their secondary effects are obvious. In this article, the authors report the results of a retrospective study of observations of patients who presented threats of premature labour and analyzed the epidemiological aspects, the aetiological factors and the therapeutic methods. It seems important to consider the risk factors in order to prevent premature labour. A decrease in the use of betamimetics and an increase in that of therapies said to be of replacement does not seem to be accompanied by a relative increase in the incidence of prematurity.

    Premature ejaculation is one of the most common sexual dysfunctions in men. Recent epidemiological studies suggest its prevalence in Australia may range from 21-31% This article will discuss the current definition of premature ejaculation from a urological perspective. It will provide an understanding of the pathogenesis of premature ejaculation, as well as assessment and management options. Premature ejaculation can have a significant adverse effect on the quality of life for the patient and his sexual partners. It can potentially lead to psychological distress, diminished self- esteem, anxiety, erectile dysfunction, reduced libido and poor interpersonal relationships. Most men feel reluctant to discuss premature ejaculation with their general practitioner despite its psychological, emotional and relational effects. Effective, evidence-based treatment options are available and physicians should feel confident when exploring ways to improve the quality of life for men with sexual dysfunction.

  10. The gender gap in suicide and premature death or: why are men so vulnerable?

    Suicide and premature death due to coronary heart disease, violence, accidents, drug or alcohol abuse are strikingly male phenomena, particularly in the young and middle-aged groups. Rates of offending behaviour, conduct disorders, suicide and depression are even rising, and give evidence to a high gender-related vulnerability of young men. In explaining this vulnerability, the gender perspective offers an analytical tool to integrate structural and cultural factors. It is shown that traditional masculinity is a key risk factor for male vulnerability promoting maladaptive coping strategies such as emotional unexpressiveness, reluctance to seek help, or alcohol abuse. This basic male disposition is shown to increase psychosocial stress due to different societal conditions: to changes in male gender-role, to postmodern individualism and to rapid social change in Eastern Europe and Russia. Relying on empirical data and theoretical explanations, a gender model of male vulnerability is proposed. It is concluded that the gender gap in suicide and premature death can most likely be explained by perceived reduction in social role opportunities leading to social exclusion.

    2014-01-01

    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.

    Greenough, Anne

    2013-10-01

    Chronic respiratory morbidity is a common adverse outcome of very premature birth, particularly in infants who had developed bronchopulmonary dysplasia (BPD). Prematurely born infants who had BPD may require supplementary oxygen at home for many months and affected infants have increased healthcare utilisation until school age. Chest radiograph abnormalities are common; computed tomography of the chest gives predictive information in children with ongoing respiratory problems. Readmission to hospital is common, particularly for those who have BPD and suffer respiratory syncytial virus lower respiratory infections (RSV LRTIs). Recurrent respiratory symptoms requiring treatment are common and are associated with evidence of airways obstruction and gas trapping. Pulmonary function improves with increasing age, but children with BPD may have ongoing airflow limitation. Lung function abnormalities may be more severe in those who had RSV LRTIs, although this may partly be explained by worse premorbid lung function. Worryingly, lung function may deteriorate during the first year. Longitudinal studies are required to determine if there is catch up growth. © 2013 Elsevier Ireland Ltd. All rights reserved.

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

    Although both biological and psychological factors are important in the etiology, the exact pathogenesis of lifelong premature ejaculation (PE) remains to be clarified. Obesity is a worldwide epidemic that contributes to many chronic diseases. Obesity is associated with erectile dysfunction, but the relationship between obesity and PE has not yet been specifically investigated. The aim of this study was to evaluate the relationships of these two conditions. Between January 2008 and December 2009, we evaluated consecutive patients with lifelong PE in the urology outpatient clinic. Control cases without lifelong PE were selected randomly among cases attending the department of internal medicine for a checkup procedure. The age and sex of control group were matched with that of the study group. Body mass index (BMI) of each case was calculated using the World Health Organization criteria by the measurements of the physician instead of relying on verbal expressions. The mean (+/-s.d.) age of the premature ejaculators was 31.7+/-5.7 (range 21-51) years and in the control cases it was 32.3+/-6.7 (range 22-54) years. The comparison of the mean (+/-s.d.) weight between the study (74.1+/-11.2 kg) and control groups (81.9+/-6.4 kg) revealed a significant difference (Pobese cases in the control group (n=26, 24.1%) was three times greater than the obese premature ejaculators (Pobesity, and we found that patients with lifelong PE were leaner than the healthy control cases.

    Objective To review and assess the update studies regarding se lective serotonin reuptake inhibitors (SSRIs) in the treatment of premature ejaculation (PE) and then provide practical recommendations and possible mechanisms concerning state of the art knowledge for the use of SSRIs in alleviating PE.Data sources Using the Medline, 48 articles published from January 1st, 1996 to August 1st, 2006 concerning the use of SSRIs and their possible mechanisms in alleviating PE were found and reviewed.Study selection PE, rapid ejaculation, early ejaculation and SSRIs were employed as the keywords, and relevant articles about the use of SSRIs and their possible mechanisms in the treatment of PE were selected.Results Many kinds of SSRIs, such as fluoxetine, sertraline, paroxetine and citalopram, have widely been employed to treat PE. However, their effects are moderate and there is no a universal agreement about the kind, dose, protocol and duration. Dapoxetine, as the first prescription treatment of PE, may change this bottle-neck situation. SSRIs are suggested to be used in young men with lifelong PE, and acquired PE when etiological factors are removed but PE still exists. Phosphodiesterase 5 inhibitors (PDE5-Is) are suggested to be employed alone or combined with SSRIs when SSRIs fail to treat PE or sexual dysfunction associated with SSRIs occurs. The protocol of taking drugs on demand based on taking them daily for a suitable period is proposed to be chosen firstly. The possible mechanisms include increasing serotonergic neurotransmission and activating 5-hydroxytryptamine 2C (5-HT2C) receptors, then switching the ejaculatory threshold to a higher level, decreasing the penile sensitivity and their own effect of antidepression.Conclusion The efficacies of the current SSRIs are moderate in the treatment of PE and they have not been approved by the FDA, therefore new SSRI like dapoxetine needs to be further evaluated.

  2. We have "born digital" - now what about "born semantic"?

    The phrase "born-digital" refers to those materials which originate in a digital form. In Earth and Space Sciences, this is now very much the norm for data: analogue to digital converters sit on instrument boards and produce a digital record of the observed environment. While much effort has been put in to creating and curating these digital data, there has been little work on using semantic mark up of data from the point of collection - what we term 'born semantic'. In this presentation we report on two efforts to expand this area: Qartod-to-OGC (Q2O) and SenseOCEAN. These projects have taken a common approach to 'born semantic': create or reuse appropriate controlled vocabularies, published to World Wide Web Commission (W3C) standards use standards from the Open Geospatial Consortium's Sensor Web Enablement (SWE) initiative to describe instrument setup, deployment and/or outputs using terms from those controlled vocabularies embed URLs from the controlled vocabularies within the SWE documents in a "Linked Data" conformant approach Q2O developed best practices examples of SensorML descriptions of Original Equipment Manufacturers' metadata (model characteristics, capabilities, manufacturer contact, etc ...) set-up and deployment SensorML files; and data centre process-lineage using registered vocabularies to describe terms (including input, output, processes, parameters, quality control flags) One Q2O use case, the Martha's Vineyard Coastal Observatory ADCP Waves instance, uses SensorML and registered vocabularies to fully describe the process of computing wave parameters from sensed properties, including quality control tests and associated results. The European Commission Framework Programme 7 project SenseOCEAN draws together world leading marine sensor developers to create a highly integrated multifunction and cost-effective in situ marine biogeochemical sensor system. This project will provide a quantum leap in the ability to measure crucial biogeochemical

    In this study, we describe trends in morbidity and mortality of preterm infants with less than 500mg birth weight in the changing landscape of obstetric and neonatal care. During a ten year study period between 2006 and 2016 we assessed outcome data for all neonates with less than 500mg birth weight born at our Neonatal Intensive Care Unit. We divided study subjects into two groups based on whether their birth date fell in the first half (2006-2010; n=39) versus the second half (2011-2015; n=27) of the study period comparing clinical outcomes in the two groups. We also assessed several clinical parameters for association with postnatal survival by comparing relative frequencies for each clinical parameter among surviving infants versus mortality cases. Survival rate for preterm neonates with less than 500mg birth weight born between 2006 and 2010 was 30.8%. This survival rate rose to 70.4% in the second half of the study period between 2011 and 2015 (ppremature birth was found to be predominantly associated with maternal hypertension or intrauterine growth restriction while in those who died premature birth due to premature rupture of membranes and spontaneous preterm labor were significantly more common. All surviving infants with less than 500mg birth weight were born via cesarean section whereas among those who died cesarean section had been performed in only 80% and vaginal delivery in 20% representing a significant difference between the groups (ppremature neonates with less than 500mg birth weight preterm delivery due to premature rupture of membranes and intrauterine infections represents the worse mortality risk. Steroid prophylaxis and measures to prevent and treat intrauterine infections with appropriate use of antibiotics can markedly improve survival in these cases. In premature neonates with less than 500mg birth weight survival is more favorable after cesarean section compared to vaginal delivery. Copyright © 2017. Published by Elsevier B.V.

    To determine if (1) tortuosity assessment by a computer program (ROPtool, developed at the University of North Carolina, Chapel Hill, and Duke University, and licensed by FocusROP) that traces retinal blood vessels and (2) assessment by a lay reader are comparable with assessment by a panel of 3 retinopathy of prematurity (ROP) experts for remote clinical grading of vascular abnormalities such as plus disease. Validity and reliability analysis of diagnostic tools. Three hundred thirty-five fundus images of prematurely born infants. Three hundred thirty-five fundus images of prematurely born infants were obtained by neonatal intensive care unit nurses. A panel of 3 ROP experts graded 84 images showing vascular dilatation, tortuosity, or both and 251 images showing no evidence of vascular abnormalities. These images were sent electronically to an experienced lay reader who independently graded them for vascular abnormalities. The images also were analyzed using the ROPtool, which assigns a numerical value to the level of vascular abnormality and tortuosity present in each of 4 quadrants or sectors. The ROPtool measurements of vascular abnormalities were graded and compared with expert panel grades with a receiver operating characteristic (ROC) curve. Grades between human readers were cross-tabulated. The area under the ROC curve was calculated for the ROPtool, and sensitivity and specificity were computed for the lay reader. Measurements of vascular abnormalities by ROPtool and grading of vascular abnormalities by 3 ROP experts and 1 experienced lay reader. The ROC curve for ROPtool's tortuosity assessment had an area under the ROC curve of 0.917. Using a threshold value of 4.97 for the second most tortuous quadrant, ROPtool's sensitivity was 91% and its specificity was 82%. Lay reader sensitivity and specificity were 99% and 73%, respectively, and had high reliability (κ, 0.87) in repeated measurements. ROPtool had very good accuracy for detection of vascular

    Domoic acid is a glutaminergic neurotoxin produced by marine algae such as Pseudo-nitzschia australis. California sea lions (Zalophus californianus) ingest the toxin when foraging on planktivorous fish. Adult females comprise 60% of stranded animals admitted for rehabilitation due to acute domoic acid toxicosis and commonly suffer from reproductive failure, including abortions and premature live births. Domoic acid has been shown to cross the placenta exposing the fetus to the toxin. To determine whether domoic acid was playing a role in reproductive failure in sea lion rookeries, 67 aborted and live-born premature pups were sampled on San Miguel Island in 2005 and 2006 to investigate the causes for reproductive failure. Analyses included domoic acid, contaminant and infectious disease testing, and histologic examination. Pseudo-nitzschia spp. were present both in the environment and in sea lion feces, and domoic acid was detected in the sea lion feces and in 17% of pup samples tested. Histopathologic findings included systemic and localized inflammation and bacterial infections of amniotic origin, placental abruption, and brain edema. The primary lesion in five animals with measurable domoic acid concentrations was brain edema, a common finding and, in some cases, the only lesion observed in aborted premature pups born to domoic acid-intoxicated females in rehabilitation. Blubber organochlorine concentrations were lower than those measured previously in premature sea lion pups collected in the 1970s. While the etiology of abortion and premature parturition was varied in this study, these results suggest that domoic acid contributes to reproductive failure on California sea lion rookeries.

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

    Fetal alcohol spectrum disorders (FASD) are associated with an increase in risk for mortality for people with an FASD and their siblings. In this study we examine mortality rates of birth mothers of children with FASD, using a retrospective case control methodology. We utilized the North Dakota FASD Registry to locate birth certificates for children with FASD which we used to identify birth mothers. We then searched for mothers' death certificates. We then compared the mortality rates of the birth mothers with an age matched control group comprised of all North Dakota women who were born and died in the same year as the birth mother. The birth mothers of children with FASD had a mortality rate of 15/304 = 4.93%; (95% CI 2.44-7.43%). The mortality rate for control mothers born in same years as the FASD mothers was 126/114,714 = 0.11% (95% CI 0.09-0.13%). Mothers of children with an FASD had a 44.82 fold increase in mortality risk and 87% of the deaths occurred in women under the age of 50. Three causes of death (cancer, injuries, and alcohol related disease) accounted for 67% of the deaths in the mothers of children with FASD. A diagnosis of FASD is an important risk marker for premature death in the mothers of children diagnosed with an FASD. These women should be encouraged to enter substance abuse treatment.

    Full Text Available In recent decades, steady progress in the field of physiopathology and the use of increasingly sophisticated technological procedures have resulted in an increase in the survival rates of babies born preterm. However, some of these individuals, although surviving, may at times be faced with severe consequences. Some conditions may be manifested at an early age (particularly dysmorphisms as well as neurological and ophthalmological conditions, whilst others (namely renal and cardiovascular events, evolve gradually and are manifested only years later. In a number of reports in literature it has been demonstrated how prematurity and consequent low weight at birth are risk factors for developing hypercholesterolemia, arterial hypertension, obesity, type 2 diabetes, QTc interval prolongation at basal electrocardiogram, early endothelial dysfunction, structural and functional cardiac modifications, and increased death rates from coronary heart disease. Even some drugs used in the neonatal management of preterm babies may have a detrimental effect on their future cardiac function. The aim of this narrative review was to overview the up to know few reports about metabolomics (a new and promising technique which allows the systematic study of the complete set of metabolites in a biological sample applied to the identification of a possible future cardiovascular system involvement in subjects born preterm. An outlook of the requirements for future researches has been also discussed.

    In this paper,we use symbolic transfer entropy to study the coupling strength between premature signals.Numerical experiments show that three types of signal couplings are in the same direction.Among them,normal signal coupling is the strongest,followed by that of premature ventricular contractions,and that of atrial premature beats is the weakest.The T test shows that the entropies of the three signals are distinct.Symbolic transfer entropy requires less data,can distinguish the three types of signals and has very good computational efficiency.

  12. Preventing the premature death of relationship marketing.

    Relationship marketing is in vogue. And why not? The new, increasingly efficient ways that companies have of understanding and responding to customers' needs and preferences seemingly allow them to build more meaningful connections with consumers than ever before. These connections promise to benefit the bottom line by reducing costs and increasing revenue. Unfortunately, a close look suggests that the relationships between companies and customers are troubled ones, at best. Companies may delight in learning more about their customers and in being able to provide features and services to please every possible palate. But customers delight in neither. In fact, customer satisfaction rates in the United States are at an all-time low, while complaints, boycotts, and other expressions of consumer discontent are on the rise. This mounting wave of unhappiness has yet to reach the bottom line. Sooner or later, however, corporate performance will suffer unless relationship marketing becomes what it is supposed to be--the epitome of customer orientation. Ironically, the very things that marketers are doing to build relationships with customers are often the things that are destroying those relationships. Relationship marketing is powerful in theory but troubled in practice. To prevent its premature death, marketers need to take the time to figure out how and why they are undermining their own best efforts, as well as how they can get things back on track.

    Chk1 inhibits the premature activation of the cyclin-B1-Cdk1. However, it remains controversial whether Chk1 inhibits Cdk1 in the centrosome or in the nucleus before the G2-M transition. In this study, we examined the specificity of the mouse monoclonal anti-Chk1 antibody DCS-310, with which the centrosome was stained. Conditional Chk1 knockout in mouse embryonic fibroblasts reduced nuclear but not centrosomal staining with DCS-310. In Chk1(+/myc) human colon adenocarcinoma (DLD-1) cells, Chk1 was detected in the nucleus but not in the centrosome using an anti-Myc antibody. Through the combination of protein array and RNAi technologies, we identified Ccdc-151 as a protein that crossreacted with DCS-310 on the centrosome. Mitotic entry was delayed by expression of the Chk1 mutant that localized in the nucleus, although forced immobilization of Chk1 to the centrosome had little impact on the timing of mitotic entry. These results suggest that nuclear but not centrosomal Chk1 contributes to correct timing of mitotic entry.

    Full Text Available Objectives: Rupture of membranes prior to the onset of labor is known as Premature Rupture of Membranes (PROM. Early and correct diagnosis is crucial in order to prevent fetal and maternal risks that can be life threatening. We aimed to investigate the diagnostic ability of the tests in PROM. Materials and Methods: Nitrazine test, fern test, amnio-dye test, biochemical tests (insulin-like growth factor binding protein-1 and placental alpha microglobulin-1 were evaluated in terms of effectiveness in diagnosis of PROM. Results: A gold standard method has not yet been defined in PROM. Diagnostic tests (nitrazine test, fern test, Insulin-like Growth Factor Binding Protein-1 “IGFBP-1” and Placental Alpha Microglobulin-1 “PAMG-1” should be used when the diagnosis is not certain following history, examination with sterile speculum and ultrasonography evaluation. Conclusion: IGFBP-1 and PAMG-1 are tests based on bedside immunochromatographic method. Especially, PAMG-1 comes into prominence with its high sensitivity and specificity.

    Progeria is characterized by clinical features that mimic premature ageing. Although the mutation responsible for this syndrome has been deciphered, the mechanism of its action remains elusive. Progeria research has gained momentum particularly in the last two decades because of the possibility of revealing evidences about the ageing process in normal and other pathophysiological conditions. Various experimental models, both in vivo and in vitro, have been developed in an effort to understand the cellular and molecular basis of a number of clinically heterogeneous rare genetic disorders that come under the umbrella of progeroid syndromes (PSs). As per the latest clinical trial reports, Lonafarnib, a farnesyltranferase inhibitor, is a potent 'drug of hope' for Hutchinson-Gilford progeria syndrome (HGPS) and has been successful in facilitating weight gain and improving cardiovascular and skeletal pathologies in progeroid children. This can be considered as the dawn of a new era in progeria research and thus, an apt time to review the research developments in this area highlighting the molecular aspects, experimental models, promising drugs in trial and their implications to gain a better understanding of PSs.

  17. Telomeres, telomerase and premature ovarian failure

    Directory of Open Access Journals (Sweden)

    Renata Košir Pogačnik

    2011-11-01

    Full Text Available Telomeres are specialized structures at the ends of chromosomes, consisting of six repeated nucleotides in TTAGGG sequence. Genome stability is partly maintained by the architecture of telomeres and is gradually lost as telomeres progressively shorten with each cell replication. Critically shortened telomeres are recognized by DNA repair mechanisms as DNA damage and the cell replication cycle stops. The cell eventually dies or undergoes cell apoptosis. Telomere represents a cellular marker of biological age and are therefore also called cell mitotic clock. The enzyme that counteracts telomere shortening by adding nucleotides to the 3’ end of DNA strand is called telomerase. It is composed of the RNA subunit (TR, which is special type of messenger RNA (mRNA, the catalytic protein subunit (TERT, which works as a reverse transcriptase and numerous additional proteins. Telomerase is active in some germline, epithelial and haemopoietic cells, but in most somatic cells the activity is undetectable. In literature, the length of telomeres is closely connected with premature ovarian failure (POF. POF is generally defined as the onset of menopause before the age of 40. The causes of disease are genetical, autoimmune, iatrogenic or if we cannot establish the cause – idiopathic. A lot of studies examined correlation between idiopathic POF, length of telomeres and telomerase activity. The studies mostly show that women with POF have shortened telomeres and decreased activity of telomerase as compared to healthy women.

    2006-01-01

    Full Text Available Background: In young adults, a family history of premature coronary artery disease (CAD, as well as genetic and environmental factors are independent risk factors for coronary artery disease. Methods: Endothelial function was studied in 30 children (21 boys and 9 girls with mean age of 14.9 +/- 2.3 years old of patients with documented CAD (men 45 and women 50 years old. Chidren did not have any history of diabetes mellitus, dyslipidemia, hypertension, and smoking (active/passive. Using vascular ultrasound, we measured resting Basal Brachial artery Diameter (BBD and Endothelium-Dependent Dilatation (EDD in response to increased flow and sublingual glyceryltrinitrate (GTN, an Endothelium-Independent Dilation (EID. These parameters were also measured in 30 control subjects with normal parents (18 boys and 12 girls with mean age of 14.2 +/- 2/5years old and results were compared with each other. Results: Adolescents in CAD group had abnormal Endothelial Dependent Dilatation or EDD/BBD (8.5 +/- 3.4% vs 11.8 +/- 4.5% in control subjects; P= 0.003.Endothelial Independent Dilatation (EID/BBD in the positive fimily history group was significantly more than control subjects (18.5 +/- 6.7% vs 11.9 +/- 5.2%; P <0.001. EDD/EID or the index of endothelial function was significantly lower in the positive family history group (0.92 +/- 0.05 vs 1+/- 0.03; P<0.001. There was no difference in EDD/EID index between those with history of premature CAD in mother (7 cases and those with history of premature CAD in father (23 cases (0.92 +/- 0.04 vs 0.91+/- 0.05. Conclusion: Normal adolescents without any cardiovascular risk factors but a history of premature coronary artery disease in one parent may have endothelial dysfunction, and there is no difference whether the CAD is in mother or father.

    2017-01-01

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

    We solve the diffusion equation by constructing the Born series for the Robin boundary condition. We develop a general theory for arbitrary domains with smooth enough boundaries and explore the convergence. The proposed Born series is validated by numerical calculation in the three-dimensional half space. We show that in this case the Born series converges regardless the value of the impedance term in the Robin boundary condition. We point out that the solution from the so-called extrapolated...

  6. The last and first frontier – emerging challenges for HIV treatment and prevention in the first week of life with emphasis on premature and low birth weight infants

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

    Objective To evaluate the effect of interventions for premature ejaculation (PE) in the management of patients with chronic prostatitis and secondary premature ejaculation. Methods Totally 90 patients diagnosed as chronic prostatitis with PE were randomly divided into control group (n=45) and interventional group (n=45). Control group received a conventional therapy consisted of oral administration of antibiotics,α-receptor blocker,and proprietary Chinese medicine for clearing away heat and promoting diuresis. Interventional group received a conventional therapy combined with treatment for ameliorating the PE symptom (oral dapoxetine on-demand and ejaculation control exercise).National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI),Chinese Index of Sexual Function for Premature Ejaculation (CIPE)-5 questionnaires,intravaginal ejaculatory latency time,and the number of coituses per week were applied for evaluating the treatment outcomes. Results Follow-up was accomplished in 35 and 38 patients in the control and interventional group.The CIPE-5 score,intravaginal ejaculatory latency time,and the number of coituses per week were significantly improved in both two groups but more significantly in interventional group (all P<0.05). The NIH-CPSI pain,urination,and quality of life subscores and total score were improved significantly in both two groups after treatment,but the NIH-CPSI pain and quality of life subscores had been improved more significantly in the interventional group (all P<0.05). The variation of NIH-CPSI was negatively correlated with that of CIPE-5 in both two groups (r=-0.362,P=0.016;r=-0.330,P=0.021). Conclusions For CP with secondary PE patients,the interventions for PE can not only improve the quality of sexual life but also help improve the NIH-CPSI pain and quality of life subscores. PE should be routinely screened and treated during the management of CP.p.

    The optimal age for assessing language difficulties in premature children remains unclear. To determine the most predictive and earliest screening tool for later language difficulties on children born preterm. A prospective population-based study in the Loire Infant Follow-up Team LIFT SUBJECTS: All children born language items of Brunet Lezine test at 24months, and the "Epreuves de Repérage des Troubles du Langage" (ERTL) at 4years. After 5years, the kindergarten teacher evaluated the vocabulary, grammar and pronunciation capacities of the child in comparison with the classroom performances. Among 1957 infants enrolled at discharge, 947 were assessed by their teacher with 12.2% (n=116) of language difficulties. Full data at all time points were available for 426 infants. The area under curve of the receiver operator characteristic curve obtained for the ASQ communication scale at 18months was significantly lower (0.65±0.09) than that obtained at 24months (0.77±0.08) and the languages items of Brunet Lezine test at 24months (0.77±0.08), and the ERTL at 4years (0.76±0.09). The optimal cut-off value for ASQ communication at 24months is ≤45 [sensitivity of 0.79 (95%CI: 0.70-0.86); specificity of 0.63 (95%CI: 0.59-0.66)]. The Ages & Stages Questionnaire communication scale at 24 corrected months appears as an acceptable test at an early time point to identify preterm children at risk of later language difficulties.

    Full Text Available Introduction: Newborns should be evaluated immediately after birth and the traditional way of assessing is to use the Apgar score. The aim of this study was to estimate the Apgar score and evaluate the first 24 hour- clinical outcome of babies born at Yazd hospitals. Methods: In a descriptive cross-sectional study, Apgar score was assessed for 462 newborns at the 4 centers of Afshar, Madar, Kargar and Bahman of Yazd. 262 out of 462 babies were born by vaginal delivery and the other 200 babies were delivered by cesarean section. The data was analyzed by using both parametric and non parametric tests. Apgar score of 7 and less was considered as abnormal. Results: In this study, the type of delivery (cesarean section or vaginal delivery, method of anesthesia (epidural or general and gender of newborn had no impact on Apgar score, but prematurity, low birth weight, premature rupture of membranes, inadequate prenatal care and the level of maternal education had influence on reduction of the Apgar score. Those babies who were in good condition and were kept beside their mothers had the highest Apgar score. Conclusion: Apgar score is a useful measure to assess the general condition of the newborns at birth and for the prediction of their morbidity, mortality and neurologic impairment.

    Hypothalamic-pituitary-gonadotropic activity was investigated in 9 girls with premature thelarche, and compared with that in 9 healthy girls and 6 girls with true precocious puberty. The gonadotropin stimulation test with luteinising hormone-releasing hormone was used. Girls with premature thelarche showed luteinising hormone response resembling that of normal girls, and follicle-stimulating hormone (FSH) response quite similar to that of girls with precocious puberty. This suggests that in premature thelarche there is a partial activation of the diencephalic-hypophyseal-gonadal axis, which affects FSH only. Premature thelarche therefore, should be considered as one of the disorders due to altered sensitivity of the hypothalamic receptors which regulate sex maturation. PMID:6779715

    Search Histologic Chorioamnionitis frequency in patients in week 28 (+/-) and pregnancy with premature rupture of membranes. Retrospective and observational study in which we studied all patients who came between June 28, 2011 and November 15, 2011 to receive obstetric care in the service of Tocochirurgical of the University Hospital of Saltillo, with greater than or equal 28 weeks of pregnancy. 598 patients were studied, and the frequency of premature rupture of membranes with histologic chorioamnionitis at term patients was, respectively, 1.7 and 5.3% in preterm labor. In the total sample frequency of histologic chorioamnionitis was 0.6% (4 patients) and, of these, 25% were term and 75% with preterm rupture. In patients with premature rupture of membranes the clinical chorioamnionitis was 0% valued by the criteria of Gibbs. The premature rupture of membranes is a risk factor important for histological chorioamnionitis. To decrease risk factors and possible complications, an established protocol must be taken.

    Full Text Available Objective: To examine health of children born by means of ART according to Perinatal Center of Saratov region for the last 2 years. Material and Methods: 70 pregnant women and 96 newborns with the use of ART were under examination. The causes of premature birth by women with ART, high degree of disease incidence among newborns and mortinatality are considered (рассматриваются in the article. Results: The important factors of amnionic membranes breaking are distinguished: maternal age, multifetation, genital and extragenital pathology, antenatal infections and fetation anomaly. Highly premature babies cause not only high neonatal disease rate and disability, but also are key element in procreational loses. Women with congelated embryo transfer less often experience premature birth, also disease rate and neurologic abnormalities are less frequent. Two and more embryo transfer more often leads to habitual miscarriage. Conclusion: Mothers-to-children health indicators after using ART demonstrate the necessity of prenatal diagnostics improvement and taking measures in monitoring such women and newborns. High quality preimplantation preparation plays a major role in fetus pathology reduction. Prescriptions and counter indications to this procedure should be thoroughly evaluated; no more than 1-2 ova should be transferred.

    Premature loss of primary teeth can result in a loss of arch length and have a negative effect on occlusion and alignment, often increasing the need for orthodontic treatment. Use of space maintainers can reduce the severity of problems such as crowding, ectopic eruption, tooth impaction and poor molar relationship. This article presents a review of the consequences of premature tooth loss and discusses the appliances commonly used for space maintenance.

    Medical technology has made significant advances over the last few decades with smaller and more dynamic pacemakers. However, technical failures leading to premature replacement is a cause of concern. We present a series of Medtronic EnRhythm devices that reached premature elective replacement indicator (ERI). The database of Centre of Heart Rhythm Disorders was searched for EnRhythm device implantation from 2006 to 2011. Battery depletion <8.5 years was considered premature considering the projected average longevity to be 8.5-10.5 years. An unexpected premature ERI was defined when it was reached within 3 months of last normal check. Device follow-up was conducted every 3 months after advisory. A total of 88 EnRhythm pacemakers were implanted. Over a median follow-up of 6.2 years (range: 0.3-9.2), 39 (44.3%) EnRhythm devices reached premature ERI. In 11 (28%), ERI was not recognized and patients were being investigated for other causes of unsteadiness or dyspnea prior to device check. Notably, three (7%) patients had premature ERI < 3.5 years. Ten (25.6%) had sudden and unexpected premature ERI. While asynchronous pacing was observed, there were no cases of absence of pacing. The rate of premature ERI for EnRhythm devices was 44.3%, significantly higher than reported by the manufacturer. Of concern, a sizeable proportion occurred unexpectedly, warranting more frequent reviews and empirical replacement in some patients. With the experience of the EnRhythm, appropriate monitoring strategies are recommended for future advisories. © 2017 Wiley Periodicals, Inc.

  6. Premature aging in telomerase-deficient zebrafish

    The study of telomere biology is crucial to the understanding of aging and cancer. In the pursuit of greater knowledge in the field of human telomere biology, the mouse has been used extensively as a model. However, there are fundamental differences between mouse and human cells. Therefore, additional models are required. In light of this, we have characterized telomerase-deficient zebrafish (Danio rerio as the second vertebrate model for human telomerase-driven diseases. We found that telomerase-deficient zebrafish show p53-dependent premature aging and reduced lifespan in the first generation, as occurs in humans but not in mice, probably reflecting the similar telomere length in fish and humans. Among these aging symptoms, spinal curvature, liver and retina degeneration, and infertility were the most remarkable. Although the second-generation embryos died in early developmental stages, restoration of telomerase activity rescued telomere length and survival, indicating that telomerase dosage is crucial. Importantly, this model also reproduces the disease anticipation observed in humans with dyskeratosis congenita (DC. Thus, telomerase haploinsufficiency leads to anticipation phenomenon in longevity, which is related to telomere shortening and, specifically, with the proportion of short telomeres. Furthermore, p53 was induced by telomere attrition, leading to growth arrest and apoptosis. Importantly, genetic inhibition of p53 rescued the adverse effects of telomere loss, indicating that the molecular mechanisms induced by telomere shortening are conserved from fish to mammals. The partial rescue of telomere length and longevity by restoration of telomerase activity, together with the feasibility of the zebrafish for high-throughput chemical screening, both point to the usefulness of this model for the discovery of new drugs able to reactivate telomerase in individuals with DC.

  7. Emerging and investigational drugs for premature ejaculation.

    McMahon, Chris G

    2016-08-01

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

    Abstract Background: Premature ejaculation (PE) is the most prevalent male sexual dysfunction. Epidemiologic findings are inconsistent concerning the risk for depression associated with PE. Objective: The aim of this study was to investigate the potential association between between depression and risk of PE. Data sources: We conducted a literature search of PubMed, Embase, and the Cochrane Library from these databases’ inception through June 2014 for observational epidemiological studies examining the association between depression on risk of PE. Study eligibility criteria: Studies were selected if they reported the risk estimates for PE associated with depression. Participants: patients>18 years of age suffering from PE. Interventions: a history of depressive disorder. Study appraisal and synthesis methods: These odds ratios (ORs) were pooled using a random or fixed effects model and were tested for heterogeneity. Subgroup analysis was employed to explore heterogeneity. Results: Eight trials involving 18,035 patients were included in the meta-analysis. Depression were statistically significantly associated with the risk of PE (OR = 1.63, 95% CI:1.42–1.87). There was no evidence of between-study heterogeneity (P = 0.623, I2 = 0.0%). The association was similar when stratified by mean age, geographical area, study design, sample size, publication year, and controlling key confounders. Limitations: The severity of depression and PE could not be identified due to unavailable data of trials. No evidence of publication bias was observed. Conclusions: These findings provide evidence that depression is associated with a significantly increased risk of PE. In addition, more prospective studies are necessary to evaluate the association and identify the ideal treatment. Systematic review registration number: CRD42016041272 PMID:27583879

    Background Based on our clinical experience, the number of dorsal penile nerves in patients with primary premature ejaculation (PPE) is not consistent with the average number (2 branches). In this study, we evaluated the number and distribution of dorsal penile nerves among healthy Chinese adults and patients with PPE.Methods The dorsal nerve of the penis, the deep dorsal vein of the penis, and the dorsal artery of the penis between the deep fascia of the penis and the albuginea penis were carefully educed, observed, and counted in 38 adult autopsy specimens. The number and distribution of the dorsal penile nerve in 128 surgical patients with PPE were determined. Results The numbers of dorsal penile nerves of the 38 cases were as follows:7 branches in 1 case; 6 branches in 1 case; 5 branches in 6 cases; 4 branches in 9 cases; 3 branches in 14 cases; and 2 branches in 7 cases. Most of the dorsal nerves were parallel to each other and in the dorsum of the penis. In only 8 cases, the branches were connected by some communicating branches. In 4 cases, 1 or 2 thin dorsal nerves continued their pathway over the ventral aspect of the penis. The average number of branches of the dorsal penile nerve in patients with PPE was 7.16. Conclusions Based on the study of 38 cases, the average number of dorsal penile nerves was 3.55 branches and that of patients with PPE was greater. These preliminary results suggest that the excessive dorsal penile nerves may have an impact on PPE via increased sensitivity and provide topographic data for the possible treatment of PPE.

    Aim: To assess the psychometric properties of the Chinese Index of Premature Ejaculation (CIPE).Methods: The sexual function of 167 patients with and 114 normal controls without premature ejaculation (PE) were evaluated with CIPE. All subjects were married and had regular sexual activity. The CIPE has 10 questions, focusing on libido, erectile function, ejaculatory latency, sexual satisfaction and difficulty in delaying ejaculation, self-confidence and depression. Each question was responded to on a 5 point Likert-type scale. The individual question score and the total scale score were analyzed between the two groups. Results: There were no significant differences between the age, duration of marriage and educational level (P>0.05) of patients with and without PE and normal controls. The mean latency of patients with PE and normal controls were 1.6±1.2 and 10.2±9.5 minutes,respectively. Significant differences between patients with (26.7±4.6) PE and normal controls (41.9±4.0) were observed on the total score of CIPE (P15 point) 19.8%, moderate (10~14 point) 62.8% and severe (<9point) 16.7%. Conclusion:The CIPE-5 is a useful method for the evaluation of sexual function of patients with PE and can be used as a clinical endpoint for clinical trials studying the efficacy of pharmacological intervention.

    In contrast to the situation in many European countries, the mortality of immigrants in France has been little studied. The main reasons for the lack of studies are based on ethical and ideological considerations. The objective of this study is to explore mortality by country of birth in Metropolitan (i.e. 'mainland') France. Complete mortality data were used to study the relative risks of mortality of the foreign- and locally-born populations by gender, age and cause of death for the period 2004-2007 in Metropolitan France. Analyses were conducted by countries of birth grouped into geographic areas and by the Human Development Index (HDI). The differentials in mortality between foreign-born and locally-born populations were not homogeneous. The figures varied by age (higher foreign-born mortality for the young; lower mortality for migrants aged 15-64 years), gender (female migrants more frequently had higher relative mortality than men migrants), country of birth (Eastern European-born migrants had higher mortality, while those born in Morocco, Central Asia, 'other Asian countries' and America had lower mortality) and cause of death (migrant mortality was higher overall for deaths caused by infectious diseases and diabetes, and lower for violent death and neoplasm). Moreover, mortality relative risks for male, violent deaths and cancer were positively associated with country-of-birth HDI, while female mortality and infectious disease mortality were negatively associated with country-of-birth HDI. Some important caveats have to be considered because the study did not control for individuals socioeconomic position in France, or length of residence in the host country. A strong healthy migrant effect was suggested and its intensity varies with age and gender (which may reflect different reasons for migration). For some specific causes of death, a lifestyle effect seems to explain mortality differentials. The associations between HDI and mortality show that mortality

    Full Text Available The cause of infant mortality is mostly due to perinatal matters. Almost 2-27% of all perinatal death is caused by prematurity with low birth weight (BBLR. Reducing mortality rate on perinatal can be achieved by observing all pregnant women and fi nding as well as addressing infl uenced factors of neonatal safety. This research aims to identify correlation between frequencies of Antenatal Care (ANC with incidence of prematurity. This is an observational study with case-control design using retrospective approach. Total population was 1335 and of 156 was choosen as research respondents deviding into 78 as case respondents and 78 as control groups. The result of statistic analysis showed that p value=0,837 (p>0,05 means frequencies of ANC did not have correlation with prematurity. Conclusion, (1 during the period of 1 January 2011 and 29 February 2012, it found 207 (8,13% premature baby delivered, (2 at about 80,8% mother who delivered premature baby had normal ANC 4 times or more with the pattern 1-1-2 in every semester, (3 statistically ANC was not having correlation with premature baby.

    Full Text Available Abstract Objective: to determine the risk factors for premature birth. Methods: retrospective case-control study of 600 pregnant women assisted in a hospital, with 298 pregnant women in the case group (who gave birth prematurely <37 weeks and 302 pregnant women who gave birth to a full-term newborn in the control group. Stata software version 12.2 was used. The Chi-square test was used in bivariate analysis and logistic regression was used in multivariate analysis, from which Odds Ratios (OR and Confidence Intervals (CI of 95% were derived. Results: risk factors associated with premature birth were current twin pregnancy (adjusted OR= 2.4; p= 0.02, inadequate prenatal care (< 6 controls (adjusted OR= 3.2; p <0.001, absent prenatal care (adjusted OR= 3.0; p <0.001, history of premature birth (adjusted OR= 3.7; p <0.001 and preeclampsia (adjusted OR= 1.9; p= 0.005. Conclusion: history of premature birth, preeclampsia, not receiving prenatal care and receiving inadequate prenatal care were risk factors for premature birth.

    Premature birth is associated with poor metabolic health in both sexes, potentially via earlier pubertal timing. We examined the associations of gestational age and premature birth (Premature girls reached puberty about 4 months later than girls with ≥ 41 weeks' gestation (time ratio = 1.04 [95% confidence interval = 1.01-1.06]), adjusted for mother' age of menarche, mother's place of birth, and smoking during pregnancy. Gestational age was not associated with onset of puberty in boys (test for interaction by sex, P Premature birth was not related to earlier onset of puberty; instead, premature girls had later onset of puberty. Thus, the association between premature birth and subsequent cardiovascular risk is probably not mediated through the timing of pubertal onset. It is unclear whether onset, duration, or tempo of puberty is more relevant to the detrimental consequences of early puberty. Further studies investigating intrauterine, infant, and childhood influences on the duration and tempo of puberty may help unravel the early origins of cardiovascular diseases.

    Full Text Available Background. Improved perinatal care has increased the survival rate of prematurely born infants. An epidemiological fact that 6–18% and more visually impaired children were prematurely born, emphasises the effect of premature birth on both visual function and development. Despite better knowledge on retinopathy of prematurity (ROP it is stressed not to underestimate refractive errors, strabismus and visual impairment after brain lesions, being more common in preterm babies.Methods. Over 1300 preterm infants with a birth weight of 1500 g or less and gestational age of 30 weeks or less, born in Maternity Hospital of Ljubljana, Slovenia in the period 1990– 1999 were examined according to contemporary paediatricophthalmologic recommendations. At least one year ophthalmologic follow-up (average 3.5 years of 594 prematurely born infants with high neonatal risk factors for ROP and with general health problems, was performed. Sex, gestational age, birth weight, artificial ventilation, exchange blood transfusion, bronchopulmonary dysplasia, respiratory distress syndrome, apnoea, septicaemia, intraventricular haemorrhage, hyperbilirubinemia were analysed for correlation with ROP and visual impairment.Results. The survival rate of the studied preterm infants was 65–87% (mean 77.3%. ROP stage 1, 2 has developed in 33 children with a birth weight under 900 g and in 10 with a birth weight 900–1200 g (altogether in 8%. ROP stage 3–5 has been registered (with or without plus disease in 7 children (below 6%. In 6 children cryo or argon laser photocoagulation has been performed and vitreoretinal surgery in 1 child (without functional results. In the studied group altogether 4 children (below 1% became blind (visual acuity < 0.05, all of them have had septicaemia. Squint has been registered in 6.9% of children, and has correlated with higher refractive error, mostly myopia. Severe optic nerve atrophy has been noticed already in the first year of follow

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

    Full Text Available Objectives: This study aimed to evaluate the changing survival rate and morbidities among infants born before 26 gestational weeks at the Sultan Qaboos University Hospital (SQUH in Muscat, Oman. Methods: This retrospective study assessed the mortality and morbidities of all premature infants born alive at 23–26 gestational weeks at SQUH between June 2006 and May 2013. Infants referred to SQUH within 72 hours of birth during this period were also included. Electronic records were reviewed for gestational age, gender, birth weight, maternal age, mode and place of delivery, antenatal steroid administration, morbidity and outcome. The survival rate was calculated and findings were then compared with those of a previous study conducted in the same hospital from 1991 to 1998. Rates of major morbidities were also calculated. Results: A total of 81 infants between 23–26 gestational weeks were admitted to the neonatal unit during the study period. Of these, 58.0% were male and 42.0% were female. Median gestational age was 25 weeks and mean birth weight was 770 ± 150 g. Of the 81 infants, 49 survived. The overall survival rate was 60.5% compared to 41% reported in the previous study. Respiratory distress syndrome (100.0%, retinopathy of prematurity (51.9%, bronchopulmonary dysplasia (34.6%, intraventricular haemorrhage (30.9% and patent ductus arteriosus (28.4% were the most common morbidities. Conclusion: The overall survival rate of infants between 23–26 gestational weeks during the study period had significantly improved in comparison to that found at the same hospital from 1991 to 1998. There is a need for the long-term neurodevelopmental follow-up of premature infants.

    We generated a model of eye growth and tested it against an eye known to develop abnormally, one with a history of retinopathy of prematurity (ROP). We reviewed extant magnetic resonance images (MRIs) from term and preterm-born patients for suitable images (n = 129). We binned subjects for analysis based upon postmenstrual age at birth (in weeks) and ROP history ("Term" ≥ 37, "Premature" ≤ 32 with no ROP, "ROP" ≤ 32 with ROP). We measured the axial positions and curvatures of the cornea, anterior and posterior lens, and inner retinal surface. We fit anterior chamber depth (ACD), posterior segment depth (PSD), axial length (AL), and corneal and lenticular curvatures with logistic growth curves that we then evaluated for significant differences. We also measured the length of rays from the centroid to the surface of the eye at 5° intervals, and described the length versus age relationship of each ray, L(ray)(x), using the same logistic growth curve. We determined the rate of ray elongation, E(ray)(x), from L(ray)dy/dx. Then, we estimated the scleral growth that accounted for E(ray)(x), G(x), at every age and position. Relative to Term, development of ACD, PSD, AL, and corneal and lenticular curvatures was delayed in ROP eyes, but not Premature eyes. In Term infants, G(x) was fast and predominantly equatorial; in age-matched ROP eyes, maximal G(x) was offset by approximately 90°. We produced a model of normal eye growth in term-born subjects. Relative to normal, the ROP eye is characterized by delayed, abnormal growth.

    By 3 to 4 months of age, infants born full-term and without known disease display associative learning and memory abilities in the mobile paradigm, where an infant's leg is tethered to a mobile such that leg kicks result in proportional mobile movement. The first purpose of this study was to examine the learning and memory abilities of a group of infants born full-term compared with those of a comparison group. Little is known about the learning and memory abilities in infants born preterm, a group at known risk for future impairments in learning and movement. The second purpose of this study was to determine if and when an age-adjusted group of infants born prematurely display associative learning and memory abilities over a 6-week period. Ten infants born full-term (38-42 weeks gestational age [GA]) and 10 infants born preterm (mobile movement were independently compared with a comparison group of 10 infants born full-term who were tethered and viewed a moving mobile but did not have control over the mobile movement. Infants in all 3 groups were seen at 3 to 4 months of age and were excluded from participation for any known visual or orthopedic diagnoses. Infants were tested using the mobile conjugate reinforcement paradigm, where one leg is tethered to an overhead mobile such that kicking with that leg results in proportional mobile movement. The kicking rates of the full-term group and the preterm group were compared with their own initial (baseline) kicking rates and with those of the comparison group. After exposure to the conjugate relationship between kicking and mobile movement, the full-term group kicked more frequently compared with their own baseline levels and compared with the comparison group, fulfilling both criteria for learning and memory. In contrast, the preterm group did not increase their kicking rate according to both criteria. These results suggest that infants born prematurely differ in their performance in the mobile paradigm as compared
