One of the pressing issues of healthcare nowadays is applying methods of molecular genetics aimed at identifying and assessing genetic risk factors and early diagnosis of perinatal pathology. Numerous studies have contributed to identifying risk factors that affect the health of newborns. The aim of this work is to investigate the associations between the development of perinatal pathology in premature and full-term infants with polymorphism of genes of the glutathione transferase family (GSTT1, GSTM1, GSTP1), renin-angiotensin system (ACE, AGT2R1). Materials and methods. The study included 110 full-term infants with asphyxia, 30 healthy full-term infants for the control group, and 125 preterm infants with perinatal infections, 21 preterm infants with broncho-pulmonary dysplasia, and 70 conditionally healthy preterm infants. A set of routine clinical and laboratory methods of research and determining gene polymorphism was performed. Results. The presence of a non-functional allele of the GSTT1 gene and DD variant of the ACE gene in newborns is associated with the development of severe perinatal asphyxia (p = 0.006 and p = 0.003, respectively). Children with GSTT1 "-" and AC AG2TR1 genotypes have significantly higher levels of diastolic pressure in the first day after birth than children with functional genotypes of these genes (p <0.05). The median mean duration of mechanical ventilation and CPAP in children with GSTT1 genotype "-" was significantly higher than that in children with GSTT1 genotype "+" (p = 0.01 and p = 0.001, respectively). Conclusion. Polymorphism studies of glutathione transferase and renin-angiotensin genes can be used to predict the severity of a child's condition after birth.

Introduction The population of children born prematurely has increased in line with improving the quality of perinatal care. It is essential to ensure to these children a healthy development. Objective We evaluate the neuromotor development of a group of preterm infants regularly assisted by a physiotherapy service in comparison to full-term newborns, checking, so the impact of the service. Materials and methods We randomly assigned preterm and full-term infants that formed two distinct groups. The group of preterm infants was inserted into a monitoring program of physiotherapy while the other infants were taken as a control group not receiving any assistance in physiotherapy. The groups were compared using the Alberta Infant Motor Scale (AIMS) at forty-week, four and six months of corrected gestational age and the scores were compared using Student's t-test, assuming a significance level of 5% (p < 0.05). Results The preterm group had significantly lower scores at 40th week compared to the control group, but subsequent scores showed no significant differences between the two groups. Conclusion The timely and adequate stimulation was efficient to promote the motor development of premature infants included in a follow up clinic.

With the wide use of magnetic resonance imaging (MRI) in clinical practice, more attention is paid to corpus callosum hypoplasia in children with various central nervous system diseases, including the cerebral palsy. We compared the areas of corpus callosum segments on the mid-sagittal MR images of the children with cerebral palsy and a control group; full-term infants and preterm infants. During the postnatal development, overall callosum area naturally increases, but single segments change differently in both absolute and relative values. In the control group, the relative area of the splenium grew insignificantly, whereas for the genu, it was stable. Children with cerebral palsy also show age-specific growth, but the area of corpus callosum is smaller compared with equal age children in the control group. We found an increased relative area of corpus callosum genu and a decrease of anterior body and splenium in the cerebral palsy group compared with the control group. The kCC index shows higher values in the control group than in any age subgroup of children with cerebral palsy. Mean values for the control group steadily increase with age, whereas in the cerebral palsy group, they remain the same. For every age-specific group, the difference of kCC was statistically significant. Mean kCC index values depend on gestational age and are statistically lower in preterm infants compared with full-term infants. Selective corpus callosum hypoplasia found in the current research could be due to Wallerian degeneration or a decreased number of axons in some of its segments. This could be explained by the disruption of neurogenesis in certain cortical areas. The morphometric index kCC can be used to detect deviations in the corpus callosum structure associated with prematurity and cerebral palsy.

Abstract Background: The factors that cause recurrent wheezing in children are complex, and premature delivery may be one of these factors. Little is known about early wheezing in preterm infants.Methods: Data were sourced from 1616 children born between 2007 and 2013 from 8 hospitals in Guangxi, China. All children were followed up by telephone or questionnaire through the sixth year of life. Children were grouped by gestational age (GA): Group A, GA ≤ 32 weeks; Group B, 32 weeks < GA < 37 weeks; and Group C, 37 weeks ≤ GA < 42 weeks.Results: The incidences and risk factors for early wheezing in preterm infants were analysed. The incidences of early wheezing were as follows: Group A > Group B > Group C. The incidence of persistent early wheezing in Group A or Group B was significantly higher than that in Group C, respectively. SGA (95% CI: 1.097 to 7.519) was a risk factor for early wheezing in group A. Male sex (95% CI: 1.595 to 4.501) and family history of allergies (95% CI: 1.207 to 3.352) were risk factors for early wheezing in group B.Conclusions: 1. New-borns with younger GAs had a higher risk of early wheezing. 2. The incidence of persistent early wheezing for preterm infants (GA ≤ 32 weeks and 32 weeks < GA < 37 weeks) was higher than that for full-term infants (37 weeks ≤ GA < 42 weeks). 3. SGA was a risk factor for early wheezing in preterm infants with a GA ≤ 32 weeks. 4. Male sex, personal history of allergies and family history of allergies were all possible factors affecting early wheezing in preterm infants with a GA > 32 weeks but < 37 weeks and full-term infants. Among them, male sex and family history of allergies were risk factors for early wheezing. 5. Mode of delivery, passive smoking, breastfeeding and invasive mechanical ventilation were not possible risk factors for early wheezing in infants of different GAs.

Aim: to evaluate EEG connectivity during the first year of age in healthy full-term infants and preterm infants with prenatal and perinatal risk factors for perinatal brain damage. Methods: Three groups of infants were studied: healthy at full-term infants (n = 71), moderate and late preterm infants (n = 54), and very preterm infants (n = 56). All preterm infants had perinatal or/and perinatal risk factors for brain damage. EEG was obtained during phase II of natural NREM sleep. EEG analysis was performed in 24 segments of 2.56 s free of artifacts. For the calculation of EEG sources, the spectral Structured Sparse Bayesian Learning (sSSBL) was used. Connectivity was computed by the phase-lag index. Results: In healthy full-term infants, EEG interhemispheric connectivity in the different frequency bands followed similar trends with age to those reported in each frequency band: delta connectivity decreases, theta increases at the end of the year, in the alpha band, different trends were observed according to the region studied, and beta interhemispheric connectivity decreases with age. EEG connectivity in preterm infants showed differences from the results of the term group. Discussion: Important structural findings may explain the differences observed in EEG connectivity between the term and preterm groups. Conclusion: The study of EEG connectivity during the first year of age gives essential information on normal and abnormal brain development.

Objective. We assessed the effectiveness of individualized developmental support in the special care nursery for low-risk preterm infants. Setting. A university-affiliated teaching hospital. Participants. Twelve healthy full-term infants, and 24 low-risk preterm infants randomly assigned to a control or an experimental group. Design. The preterm control group received standard care and the preterm experimental group received individualized developmental care at the same special care nursery. Outcome Measures. Medical, behavioral (Assessment of Preterm Infants' Behavior and Prechtl's Neurological Examination of the Full-Term Newborn Infant), and electrophysiologic outcome (using quantitative electroencephalography with topographic mapping) of all three groups was assessed 2 weeks after the expected due date. Results. No between-or among-group medical differences were seen for this low-risk, healthy sample. The preterm experimental group showed behavioral and electrophysiologic performances comparable to those of the full-term group, whereas the preterm control group performed significantly less well. Behavioral measures suggested significantly poorer attentional functioning for the preterm control group. Electrophysiologic results implicated the frontal lobe. Conclusions. Individualized developmental intervention supports neurobehavioral functioning as measured at 2 weeks post-term. It appears to prevent frontal lobe and attentional difficulties in the newborn period, the possible causes of behavioral and scholastic disabilities often seen in low-risk preterm infants at later ages.

CATAMNESTIC OBSERVATION OF CARDIOVASCULAR STATUS IN PRETERM INFANTSM.O. Gonchar, A.D. BoichenkoTo identify peculiarities of the diastolic function development of the heart ventricles in preterm infants following clinical and instrumental examination in the neonatal period and in the process of catamnestic observation the study involved examination of 244 preterm infants at gestation age from 260-7 to 376-7 weeks. Control group comprised 100 healthy full-term infants. The study showed that peculiarities of the development of diastolic function of the heart ventricles in prematurely born children included diastolic dysfunction by the type of delayed relaxation, which is typical for the fetus, until the child reaches the postconceptual age of 39-41 weeks. Normalization of the diastolic function of the heart ventricles occured in 46/61 (75.41 ± 5.51%, p = 0.1·10-6) prematurely born children to 5-6 months of actual age, in 15/61 (24.59 ± 5.51%) children to 6-8 months of actual age. Spontaneous closure of open oval window up to the age of 1 year occurred in 22/32 (68.75 ± 8.19%, p = 0.009) full-term newborns and in 21/61 (34.43 ± 6.08%) preterm infants. Hemodynamically significant patent arterial duct in 58.82 ± 11.94% of children spontaneously closes during the first three months of life. The incidence of myocardial dysfunction in newborns from mothers with extragenital pathology increased to 89.39 ± 3.79% versus 76.67 ± 5.46%, p = 0.046 children born from healthy women. The presence of extragenital pathology in mothers, including cardiovascular disorders, is a risk factor for the development of cardiovascular diseases in preterm children.Key words: preterm infants, myocardial dysfunction, catamnesis.  КАТАМНЕСТИЧНЕ СПОСТЕРЕЖЕННЯ СТАНУ СЕРЦЕВО-СУДИННОЇ СИСТЕМИ У ПЕРЕДЧАСНО НАРОДЖЕНИХ ДІТЕЙГончарь М.О., Бойченко А.Д.З метою визначення особливостей становлення діастолічної функції шлуночків серця у передчасно народжених дітей на підставі клініко-інструментального дослідження в неонатальний період та в процесі катамнестичного спостереження обстежено 244 передчасно народжені дитини зі строком гестації від 26 до 37 тижнів. Контрольна група – 100 здорових доношених новонароджених. За результатами дослідження встановлено, що до особливостей становлення діастолічної функції шлуночків серця у передчасно народжених дітей відноситься реєстрація діастолічної дисфункції за типом уповільненої релаксації, що є характерним для плода, до досягнення дитиною постконцептуального віку 39-41 тиждень. Нормалізація діастолічної функції шлуночків серця відбувається у 46/61 (75,41±5,51%, р=0,1·10-6) передчасно народжених дітей к 5-6 місяцю фактичного віку, у 15/61 (24,59±5,51%) дітей – к 6-8 місяцям фактичного віку. Спонтанне закриття відкритого овального вікна до віку 1 року відбувається у 22/32 (68,75±8,19%, р=0,009) доношених новонароджених та у 21/61 (34,43±6,08%) передчасно народжених дітей. У 58,82±11,94% дітей з гемодинамічно значущою ВАП відбувається її спонтанне закриття на протязі перших трьох місяців життя. Частота зустрічальності міокардіальної дисфункції у новонароджених від матерів з екстрагенітальною патологією зростає до 89,39±3,79% проти 76,67±5,46%, р=0,046 дітей народжених від здорових жінок. Наявність у матерів екстрагенітальної патології, в тому числі патології серцево-судинної системи, є факторами ризику розвитку серцево-судинних розладів у передчасно народжених дітей.Ключові слова: передчасно народжені діти, міокардіальна дисфункція, катамнез. КАТАМНЕСТИЧЕСКОЕ НАБЛЮДЕНИЕ СОСТОЯНИЯ СЕРДЕЧНО-СОСУДИСТОЙ СИСТЕМЫ У НЕДОНОШЕННЫХ ДЕТЕЙГончарь М.А., Бойченко А.Д.С целью определения особенностей становления диастолической функции желудочков сердца у недоношенных детей на основании клинико-инструментального исследования в неонатальный период и в процессе катамнестического наблюдения обследовано 244 преждевременно рожденных ребенка со сроком гестации от 26 до 37 недель.

This study examines the infant–father attachment in infants born preterm (<  1500 g at birth and/or <  37 weeks gestation) in comparison to full-term infants. The infant–father attachment was assessed using the Strange Situation Procedure at a (corrected) age of 15 months. We found at least half of preterm and full-term infants (50.0% and 56.5 % respectively) securely attached to their fathers, and no significant overall difference was observed concerning the distribution of attachment quality comparing the two groups. In light of the fact that preterm infants tend to have numerous neurodevelopmental problems, it is encouraging that significant differences were not found in the distribution of the attachment quality among the groups. Therefore, from the perspective of attachment research, it would be highly beneficial to include fathers in the care of their preterm infants.

Objective. To investigate the effect of body rocking on infant respiratory behavior during sleep. Methods. Eighteen infants with documented obstructive sleep apneas were studied. There were eight premature infants with persistent bradycardias and 10 infants born full-term, admitted after an idiopathic apparent life-threatening event. No cause for the obstructive apneas was found. The infants were recorded with polygraphic techniques during two successive nights. They were randomly assigned to a rocking or a nonrocking mattress. The conditions were reversed the following night, in a crossover design. Results. In both groups of infants, no significant difference was seen between the two consecutive nights for most of the variables studied: total sleep time, the proportion of non-rapid-eye-movement and rapid-eye-movement sleep, the number of arousals, the number and maximal duration of central apneas, the frequency of periodic breathing, the level of oxygen saturation, and heart rate. During the nonrocking nights, all infants had repeated obstructive breathing events. In seven of the eight preterm infants and in nine of the 10 full-term subjects, body rocking was associated with a significant decrease in the frequency of obstructive events. During rocking, in the preterm infants the obstructions fell from a median of 2.5 to 1.8 episodes per hour (P = .034). In the full-term infants, rocking reduced the obstructive events from a median of 1.5 obstructions per hour to 0.7 (P = .005). No difference was seen for the duration of the obstructive episodes. Conclusion. In preterm and full-term infants prone to obstructive sleep apneas, gentle side-to-side body rocking is associated with a significant decrease in the frequency of upper-airway obstructions.

Infants born prematurely (before completion of 37 weeks of gestation) are at increased risk of morbidity and mortality due to vaccine preventable diseases, mostly because of their immunological immaturity and failure of transfer of maternal protective antibodies. Despite their great need of being vaccinated, concerns on vaccine safety and efficacy, constitute the main reasons for which vaccinations are often delayed in this group. In this review we summarize the latest evidence on vaccine safety, efficacy and immunogenicity in preterm infants which is similar to full-term infants. Therefore there is no reason for delaying vaccination in this population.
