We conducted a study of markers of endothelial dysfunction and angiogenesis regulation, as well as the identification of the main lymphocyte populations, activated CD3 (+) CD95(+)-cells and cytokine-producing CD4 (+) IFN-γ(+)-, CD4 (+) IL-4(+ )-lymphocytes in the 1st trimester of gestation in women with ART-induced pregnancy and spontaneous pregnancy. We used the same indicators to assess the immune status of ELBW infants at birth and at the post-conceptual age of 38-40 weeks. It was determined that the risk factors of very early preterm delivery are: threatened miscarriage, chronic placental insufficiency, endothelial dysfunction, increased spontaneous production of intracellular cytokines...

Introduction: Hospitalization in neonatal intensive care unit may leads to many stresses for premature infants. Since premature infants cannot properly process stressors, identifying interventions that reduce the stress level for them is seems necessary. The aim of present study was to compare the effects of Field massage and Gentle Human Touch (GHT) techniques on the urine level of cortisol, as an indicator of stress in preterm infants. Methods: This randomized, controlled clinical trial was carried out in Al-Zahra hospital, Tabriz...

Diagnosis of mitochondrial respiratory chain disorder (MRCD) is often difficult. Its pathogenesis is still unclear. We diagnosed MRCD by measuring the activity of the mitochondrial respiratory chain enzyme, and the patient also had hemophagocytic lymphohistiocytosis (HLH). A preterm female infant was born at 34 weeks of gestation. On day 6, HLH was revealed by bone marrow aspiration. She died on day 10 due to uncontrollable HLH. An autopsy was performed, and we measured the activity of the mitochondrial respiratory chain enzyme in the liver, muscle, and heart...

Studies suggested the presence of foetal adrenal rhythms of cortisol, which are entrained in antiphase to maternal rhythms. In contrast, neonates are thought to have no adrenal rhythm until 2-3 months after birth. To test the hypothesis that a foetal-type adrenal rhythm is preserved after birth, saliva samples were collected from 65 preterm/term infants during hospital stay (30-40 weeks corrected age) at 10:00 and 19:00 h. Cortisol levels were assessed for their diurnal difference and dependence on antenatal/postnatal clinical variables...

Human breast milk is the most natural and ideal food for the baby. Breastfeeding provides benefits for maternal and child health, child immune function, growth and development, and society. The operation of human milk bank and the use of donor human milk undoubtedly provides a new way of nutrition support for the preterm infants without their own mother's milk and a new kind of treatment for other diseases. Present research on the composition of breast milk focuses on the variety and quantity of proteins, bioactive substances, probiotics and cell population...

BACKGROUND: The benefits of breast milk are well described, yet the mechanistic details related to how breast milk protects against acute and chronic diseases and optimizes neurodevelopment remain largely unknown. Recently, breast milk was found to contain stem cells that are thought to be involved in infant development. PURPOSE: The purpose of this review was to synthesize all available research involving the characterization of breast milk stem cells to provide a basis of understanding for what is known and what still needs further exploration...

OBJECTIVE: Early growth rates and feeding advancement rates of preterm infants are thought to influence later health. Feeding advancement is often difficult due to feeding intolerance. Exclusive human milk feeding improves tolerance, but can result in a lower weight gain rate. The addition of human milk fortifier has advantages for growth, but there are concerns that it may nullify the beneficial effect of human milk on tolerance. Therefore, the objective of this study was to evaluate the relationship between the amount of fortified human milk or formula and feeding tolerance and growth in preterm infants...

Infants born prematurely are highly vulnerable to brain injury and susceptible to seizures in the first weeks of life. Many neonatal seizures occur without reliable clinical signs and are detectable only on electroencephalogram (EEG); understanding EEG findings in these neonates is crucial for providing appropriate care. This can be challenging, as EEG background activity and patterns vary considerably with gestational age. Some physiologic preterm EEG patterns, such as rhythmic temporal theta activity or delta brushes, may be sharply contoured and appear similar to epileptic EEG patterns later in life...

Introduction: Although preterm birth represents a risk factor for early mother-infant interactions, few studies have focused on toddlerhood, an important time for the development of symbolic play, autonomous skills, and child's socialization competences. Moreover, no study has looked at the effect of birth weight on mother-child interactions during this period. Expanding on the available literature on prematurity, the main objective of this study was to explore the quality of mother-toddler interactions during play, using a longitudinal research design, as well as taking into account the effect of birth weight...

The criteria for newborn hospital discharge of the newborn must include physiological stability and family competence to provide newborn care at home. In this document, the Committee of Standards of the Spanish Society of Neonatology reviews the minimum criteria to be met before hospital discharge of a term newborn infant. A review included the hospital discharge criteria for the late preterm infants, as these infants are often not hospitalised and remain with their mother after birth. A shortened hospital stay (less than 48h after delivery) for healthy term newborns can be considered, but it is not appropriate for every mother and newborn...

: Noradrenaline (NA) is beneficial in the treatment of term newborns with cardiovascular compromise due to sepsis or pulmonary hypertension, but experiences with NA in preterm infants are limited. The aim of this study is to describe the efficacy and safety of NA in preterm infants. Patient records of preterm infants ≤32 weeks' gestation admitted to two hospitals between 2004 and 2015 and who received NA were reviewed for perinatal morbidities and mortality. Clinical details were collected at the time of NA use, and response on blood pressure, perfusion and oxygenation was documented as well as possible side effects...

INTRODUCTION: To determine the accuracy of estimated fetal weight (EFW) at the limit of viability in a delivery room setting and its impact on the prediction of neonatal outcome. MATERIAL AND METHODS: In this retrospective, single-center cohort study we included patients with preterm birth between 230/7 and 260/7 weeks of gestation. Neonates were divided into 3 groups according to birth weight at delivery (accuracy index 90-110%, <90%, >110%). Neonatal outcome for each group was categorized into survival with and without impairment and death, with a follow-up period of 6 weeks...

Parents of preterm infants commonly experience separation from their infant or exclusion from their role as primary caregivers during the hospital care of their infant, which may impair parent-infant bonding and parents' psychological well-being. Therefore, we developed the Close Collaboration with Parents™ intervention to improve staff skills in communicating and collaborating with parents in neonatal intensive care units (NICU), to increase parents' presence and participation into infant care, and to improve parent-infant bonding and, thereby, parents' psychological well-being and later child development...
