Abstract:
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 major role, other factors are also important, above all fetal distress, perinatal hypoxia and functional immaturity of all organs.

Abstract:
The purpose of this chapter is to summarize the findings of the nursing research on parenting the prematurely born child. This research focused on eight general areas: impact of the home environment on infant development status, the relationship between premature infants and their mothers during the first 2 years, parenting during hospitalization, maternal concerns about infant discharge, fathering, subpopulations of premature infants, parenting after the first 2 years, and interventions to improve parenting. There is a need to strengthen the design and conceptualization of these studies, to move toward more intervention research, and to do research that is more culturally sensitive, especially toward fathers, ethnic and cultural minority groups, and the poor.

Abstract:
SummaryStudy aim: Premature birth is one of the major problems of obstetrics, leading to numerous complications that are associated with prematurity, for instance balance disorders. The aim of the study was to assess the impact of premature birth on the ability to maintain balance in children commencing their school education. Material and methods: The study included children aged 6-7 years. The study group consisted of 59 children (31 girls and 28 boys, mean age 6.38 ± SD 0.73) born prematurely between 24 and 35 weeks of gestation. The control group consisted of 61 children (28 girls and 33 boys, mean age 6.42 ± 0.58) born at term. The research utilized standardized test tools - one-leg open-eyed and closed-eyed standing test, one-leg jumping test - and an original questionnaire survey. Results: The children born at term achieved better results in the majority of tests. The comparison of girls and boys born pre­maturely and at term showed no statistically significant difference between them in terms of dynamic balance, static balance or total balance control. The comparison of the tests performed on the right and left lower limb in prematurely born children showed no statistically significant differences. Conclusion: Premature birth affects the ability to maintain body balance. The results of the study indicate the need to develop coordination skills that shape body balance in prematurely born children.

Abstract:
Introduction: Preterm delivery is the delivery before 37 weeks of gestation are completed. The incidence of preterm birth ranges from 5 to 15%. 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.

Abstract:
ABSTRACT Measurements of (a) 17-hydroxyprogesterone (17-OHP) in blood collected onto filter paper after heel puncture by lancet and (b) steroid metabolites in random collections of urine, were made in human infants born from 25 weeks of gestation onwards. The concentration of 17-OHP in blood eluted from filter paper samples was inversely related to both gestational age and birth weight. In mature infants, 17-OHP concentrations fell rapidly soon after birth, whereas concentrations remained high over the first month of life in infants born earlier than 33 weeks of gestation. Sulphated urinary steroids were identified as having a 3β-hydroxy-5-ene structure and although the pattern of excretion was similar in mature and premature infants, significantly higher concentrations were found in the premature group. Steroid metabolites normally present when concentrations of circulating 17-OHP are increased due to 21-hydroxylase deficiency were not detectable in urine samples collected from infants born prematurely. Where direct comparison of 17-OHP in blood spots and urinary steroid metabolites was possible, the concentrations of 17-OHP in blood samples paralleled 3β-hydroxy-5-ene steroid metabolites in urine. The results suggest that a circulating cross-reacting 3β-hydroxy-5-ene steroid may be responsible for increased concentrations of 17-OHP in infants born prematurely. Increased concentrations of both 17-OHP in blood spots and steroid sulphates in urine were associated with stress in premature, but not in more mature, infants suggesting that in infants born prematurely postnatal stress may delay adrenal maturation.

Abstract:
Introduction. Prematurity is a great health problem in our country and in the world. There are more than 11% of premature births in America annually, and in Europe this rate is between 5-10%. In Vojvodina, 9% of babies are born prematurely. Intracranial hemorrhage takes a significant place in the morbidity of prematurely born children. Intracranial hemorrhage in premature newborn infants Incomplete CNS development of premature infants causes numerous complications, but it is also the factor which enables survival of extremely immature infants without sequelae. The management protocol depends on the level of hemorrhage. Early diagnosis of intracranial hemorrhage and determination of the level of hemorrhage are of utmost importance for disability prevention. Ultrasound in monitoring intracranial hemorrhage Brain monitoring of prematurely born babies is performed by ultrasound. This type of visualization has several advantages over other techniques: it is mobile, so called "bedside technique", it is relatively cheap, it may be repeated several times, it is possible to define the exact time of hemorrhage and monitor its absorption from day to day. Ultrasound is safe, and there is no ionized radiation. No sedation is required for ultrasound examination. The examination is not painful. Conclusion The frequency of ultrasound depends on the level of hemorrhage, presence or absence of ventriculomegally/ hydrocephalus, as well as on the surrounding cerebral parenchyma. .

Abstract:
ABSTRACTInfants 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.

Abstract:
The aim of this study was to describe the ways premature infants and their mothers emotionally interact in the first weeks of their lives. In order to understand the intersubjective dyadic interaction between mother and premature infant, a qualitative and descriptive approach to research has been adopted. Four dyads comprised of primiparae women and their newly-born premature infants took part in the study. The babies were born prematurely after 28 to 35 weeks of gestation and admitted to the neonatal intensive care unit (NICU). Data was collected filming the first dyadic interaction with infant in the mother’s arms, lasting between 15 to 30 minutes. After that first registry, dyadic behaviors between mother and baby were described and categorized following the intersubjective categories suggested by Fiamenghi (1999) and Fiamenghi et al. (2010). Results showed that dyads display positive emotions, with infants’ behaviors falling into the categories of negotiation, interaction and emotional curiosity; as well as a low frequency of negative behaviors. The outcome of this research reinforces the need to adopt a humanizing approach to prematurely born infants and their mothers in NICU, as well as training and awareness of the whole multidisciplinary team that deals with them.

Abstract:
Sammanfattning Mål: Tidigare studier visar att delar av den fysiska och psykiska tillväxten och utvecklingen hos för tidigt födda barn kan påverkas av den förkortade graviditetsperioden. De odontologiska aspekterna av prematuritet har ännu inte till fullo studerats. Syftet med denna studie är att undersöka om tandmognaden påverkas av för tidig födsel och om enskilda tänder i högre utsträckning är mer påverkade.Material och Metod: I studien deltog 116 barn: 36 extremt för tidigt födda barn (extremely preterm - EPT), 38 mycket för tidigt födda barn (very preterm – VPT) och 42 fullgångna kontroller (controls – C). Panoramaröntgenbilder analyserades av fem kalibrerade observatörer, enligt en metod som utvecklats av Demirjian och Goldstein. Röntgenbilderna avidentifierades och mognadsgraden av de 7 permanenta tänderna i underkäkens vänstra sida (tand 31-37) bedömdes enligt ett 8-stegs system. De 7 bedömningarna adderades sedan till en tandmognadspoäng (maturity score) som motsvarade barnets tandmognadsgrad. Detta möjliggjorde jämförelser på såväl gruppnivå som tandnivå. Observatörernas tillförlitlighet och metodens reproducerbarhet utvärderades genom att 27 slumpvis utvalda röntgenbilder bedömdes ytterligare en gång. Statistiska analyser utfördes av studiens resultat samt av reproducerbarheten.Resultat: Resultatet, med hänsyn till variationer i observatörernas bedömningar, visade att EPT-gruppen hade en genomsnittlig tandmognadspoäng mellan 81.9 och 86.7, VPT 85.2-89.1 och kontrollgruppen 88.1-91.0. Samtliga fem observatörer uppvisade statistiskt signifikanta skillnader mellan EPT-gruppen och kontrollgruppen (p≤0.006). På tandnivå uppvisade alla observatörer en signifikant fördröjning (p≤0.002) av tandmognaden för tand 37 när EPT-gruppen jämfördes mot kontrollgruppen. Signifikanta skillnader mellan ett flertal andra tänder erhölls men konsensus mellan observatörerna saknades. Överensstämmelsen inom varje enskild observatör (intra-observer agreement) beräknades med ett Kappa-test, där resultaten varierade mellan 0.16-1.00. Kappa-beräkningen av reproducerbarheten mellan samtliga observatörer (inter-observer agreement) varierade mellan 0.31-0.71.Slutsats: Resultaten i denna studie tyder på en allmän försening av tandmognaden vid 9 års ålder hos de extremt för tidigt födda barnen (EPT), jämfört med fullgångna barn (C). En förkortad gestationsperiod tycks indikera en fördröjning av tandmognaden jämfört med tandmognaden hos fullgångna barn.

Abstract:
Background: Extrauterine growth restriction (EUGR) is multifactorial in etiology and predisposes infants to multiple morbidities that can be significantly ameliorated by adequate nutrition and appropriate longitudinal growth. Current strategies to reduce the risk of EUGR include optimization of parental nutrition, varying schedules of feeding advances, and caloric supplementation. Very low birthweight (VLBW) preterm infants are particularly affected by EUGR, therefore ensuring adequate postnatal growth is an essential component in improving the long-term health outcomes for VLBW infants. The objectives of this observational study were to examine potential risk factors for growth failure among premature infants that did not respond to caloric and volume supplementation. Methods: We conducted a retrospective chart review of all infants born at the University of Massachusetts level III NICU from January 2016 to June 2020. Growth was tracked using PediTools electronic gestational age and growth calculators. (17) We reviewed the EMRs of infants who met the criteria for EUGR at the time of hospital discharge for a variety of potential factors affecting growth. Results: Overall, a total of 448 infants were screened with a final study cohort of 358 infants, of which 13% were discharge with EUGR. Analysis of demographic and clinical characteristics of infants with EUGR before and after nutritional intervention showed no statistically significant differences between the two cohorts. Pre-protocol, only weight percentiles and z-scores were statistically significant. Post-protocol, the change in z-score was also statistically significant. The only factor found to be statistically significantly different between was Necrotizing enterocolitis (NEC). Timing of EUGR in the pre-protocol groups occurred between 33-35 weeks, while in the post-protocol group EUGR occurred between 32 and 37 weeks (Figure 2). Conclusions: Our findings confirmed the presence of several factors that have been previously shown to increase risk for EUGR, including male sex, lower gestational age, lower birth weight, and the occurrence of NEC. It also identified an additional risk factor, that of being born “constitutionally small”. In the post-protocol cohort, the change in z-score was statistically significant in addition to birth weight percentile and z-score and discharge weight percentile in z-score. The window in which EUGR occurred as well as the interquartile range was significantly widened post-protocol. These data suggest that the volume supplementation protocol successfully addressed the causes of EUGR in some infants, but other mechanisms may have occurred in infants who were still discharged with EUGR post-protocol.

Abstract:
Hybrid diffuse optical devices allows for the non-invasive and continuous monitoring of the cerebral haemodynamics and metabolism. Such devices can be portable and are relatively inexpensive, therefore available at the bed- or cot side. These advantages make the technology appealing and useful for a variety of applications. For my Ph.D. thesis, I have worked on the development of new devices that integrate diffuse correlation (DCS) and time resolved near-infrared spectroscopy (TRS) and on broadening their field of applications. Preterm newborn infants are one of the target populations for such a neuromonitor. Premature newborns are at a risk of impaired neurodevelopment due to brain lesions that can be developed during first hours and days of life. In spite of the fact that these lesions are often due to episodes of abnormalities of the cerebral haemodynamics, related to oxygen supply to the brain and its consumption, these parameters are not currently monitored due to the lack of an appropriate technology. In order to meet this need, the BabyLux project aimed at developing a hybrid diffuse optical device that could be used to assess the cerebral well-being of the premature newborn infants. In the framework of this project, I have developed and built the Baby-Lux device. Specifically, I have integrated DCS, to measure microvascular blood ow, and TRS, to measure microvascular blood oxygenation, into a user-friendly device, a prototype for a future medical grade device. In this thesis I report results of tests in laboratory settings in order to assess the device performance in best-case scenario. Furthermore, I explore the device's limits in precision and accuracy, through simulated DCS and TRS data with realistic noise added, and I describe the influence of a variety of experimental and analysis parameters. In addition, I demonstrate a high correlation between cerebral blood ow (CBF) measurement performed by the BabyLux device and by the gold standard positron emission tomography with 15O-labeled water on a neonatal piglet model. This proves the robustness of the BabyLux solution for blood ow measurement and provides a calibration formula to convert the DCS-measured blood ow index into traditional ow units. Finally, the device was tested in clinical settings, on healthy term newborns. It allowed for following cerebral haemodynamics and metabolism during the transition after birth. Reproducibility over probe replacement appeared improved with respect to commercial oximeters for tissue blood oxygen saturation and comparable to other technologies for the blood ow. For an additional study on adult healthy volunteers, I have constructed a hybrid device integrating a commercial DCS and a prototype for a TRS device. This could serve as a neuro-monitor for following the cerebral response to transcranial direct current stimulation. This is a non-invasive form of stimulating the brain that has proven to be effective for cognitive augmentation and for treating pathological conditions.In conclusion, the work presented in this thesis paves the way to a new generation of neonatal neuro-monitors that can be developed for extensive, multi-center clinical testing and ultimately allow a robust and accurate assessment of the cerebral well-being of the newborns. As far as the adult brain is concerned, I have introduced a new method for monitoring the cerebral response during transcranial direct current stimulation that can be exploited for protocol and dosage definition and, eventually, for the on-line monitoring of the cerebral response to the stimulation, tailoring the intervention to each subject's condition.<br>Las tecnologías de óptica difusa permiten estimar de manera no invasiva y continua la hemodinámica y el metabolismo cerebral a través de instrumentos manejables, de coste relativamente bajo y disponibles al lado de la cama o la cuna del paciente. En mi tesis doctoral he desarrollado un instrumento que combina dos técnicas de óptica difusa: diffuse correlation spectroscopy (DCS) y time resolved near-infrared spectroscopy" (TRS). Además, he contribuido a explorar nuevas aplicaciones para estas tecnologías. Los prematuros recién nacidos son unas de las poblaciones objetivos para este tipo de aparato de monitorización cerebral. El desarrollo cerebral de los prematuros es más susceptible de lesiones cerebrales desarrolladas en las primeras horas o días de vida. Aunque estas lesiones cerebrovasculares son generalmente causadas por anomalías en la hemodinámica cerebral, es decir en el flujo sanguíneo hacia el cerebro o en el nivel de oxigenación del tejido cerebral, estos parámetros no son monitorizados de forma continua porque no existe una tecnología que permita hacerlo. El proyecto Baby Lux, en el que participé activamente, tenía el objetivo de desarrollar un instrumento que utilizara óptica difusa para monitorizar el cerebro de los bebés prematuros. Con el consorcio del proyecto Baby Lux, he desarrollado y construido un aparato que combina DCS, para medir el flujo sanguíneo micro-vascular, y TRS, que mide la oxigenación del flujo microvascular, con el objetivo de que fuera preciso, exacto y sólido como para poder utilizarse en aplicaciones clínicas. En esta tesis se exploran sus límites de precisión y exactitud, simulando datos DCS y TRS, y cómo estos se ven influenciados por varios parámetros experimentales y de análisis. Además, se demuestra una fuerte correlación en lechones entre el flujo sanguíneo medido por Baby Lux y lo medido por tomografía por emisión de positrones (PET) con 15O como radiofármaco, técnica de referencia para medir el flujo sanguíneo cerebral. Esto demuestra la habilidad de la medida de flujo de Baby Lux y, además, permite calibrar el flujo sanguíneo medido por la DCS y convertirlo en la unidad tradicional de medida de flujo. Finalmente, el dispositivo fue ensayado en hospitales. La hemodinámica cerebral fue monitorizada en los minutos posteriores al nacimiento de bebés sanos. La reproducibilidad de las medidas de Baby Lux demostró una calidad superior respecto a los oxímetros cerebrales actuales y comparables a otras tecnologías para medir el flujo cerebral. Estudios adicionales han investigado la hemodinámica cerebral de voluntarios adultos y sanos con otro aparato que he construido combinando una DCS comercial y un prototipo para una TRS. He demostrado que este aparato puede ser útil para investigar la respuesta cerebral a la estimulación eléctrica transcraneal, una forma de estimulación no invasiva que ha dado buenos resultados para tratar condiciones patológicas o para mejorar capacidades cognitivas. En resumen, el trabajo presentado en esta tesis abre el camino hacia una nueva generación de instrumentos capaces de monitorizar el cerebro de los bebés prematuros, que puedan ser utilizados en ensayos clínicos en varios hospitales y de forma extensiva. Además, he introducido una nueva técnica para monitorizar la respuesta cerebral a la estimulación transcraneal que pueda ayudar a la hora de definir protocolos y dosis de la estimulación y que permite adaptar el protocolo a cada sujeto.

Abstract:
More than half a million babies are born prematurely in the United States, and the rate of preterm birth (PTB) is on the rise [1]. Infants born prematurely account for a high percentage of perinatal mortalities, and preterm infants that survive are at risk for long-term morbidities including neurologic, respiratory, cardiovascular and gastrointestinal complications [2]. Altered mechanical and biochemical properties of the uterine cervix are suspected to cause premature and spontaneous cervical dilation, which is associated with a leading cause of PTB known as cervical insufficiency (CI). The impact of this condition is unknown because diagnosing CI remains controversial. Multiple etiologies are believed to lead to an insufficient cervix, or a soft cervix. Yet, there is no standard method to quantify the mechanical strength of the cervix, limiting the ability to discern these etiologies, to stage the progression of labor, and to identify and manage high-risk CI patients.
