Women who delivered preterm infants have excess cardiovascular disease, but vascular pathways linking these conditions are not understood. We considered that higher blood pressure over 25 years among women with preterm delivery may be associated with coronary artery calcification (CAC). The CARDIA study (Coronary Artery Risk Development in Young Adults) enrolled 1049 black and white women with births between 1985 and 2010 (n=272 ever preterm [<37 weeks]; n=777 all term births [≥37 weeks]). Latent mixture modeling identified blood pressure trajectories across 20 years, and these were related to CAC at years 20 and 25...

Inflammation caused by perinatal infection, superimposed with hypoxia and/or hyperoxia, appears to be important in the pathogenesis of preterm neonatal encephalopathy, with white matter particularly vulnerable during the third trimester. The associated inflammatory response is at least partly mediated through Toll-like receptor (TLR)-dependent mechanisms. Immunohistochemistry, gene expression, and behavioral studies were used to characterize white matter development and determine TLR3 and TLR4 expression and accumulation in the neonatal ferret brain...

BackgroundWe tested the hypotheses that caffeine therapy would increase the ventilatory response to hypercarbia in infants above the effect of maturation and those with a weaker ventilatory response to hypercarbia would be more likely to subsequently develop apnea that required treatment.MethodsInfants born at less than 34 weeks of gestation underwent a steady-state hypercarbic challenge using 0, 2, and 4% carbon dioxide soon after birth that was repeated at weekly intervals. The results of the initial study were compared between infants who did or did not subsequently develop apnea requiring treatment with caffeine...

Refeeding Syndrome (RFS) is a well-known group of symptoms which occur after the introduction of enteral or parenteral nutrition in undernourished patients. Intrauterine growth restriction (IUGR) is the equivalent of postnatal RFS following the beginning of feeding. The aggressive parenteral nutrition of neonates with very low birth weight (VLBW) resulting from the termination of intrauterine transplacental nutrition is a source of biochemical disorders. The aim of this study was to analyze metabolic disorders in preterm infants during the 1st week of life and to determine the hypophosphatemia risk factors in low birth weight neonates receiving parenteral nutrition...

OBJECTIVE: N-terminal-probrain natriuretic peptide (NT-proBNP) is a marker of hemodynamically significant patent ductus arteriosus (HsPDA) in preterm infants. In this study, we assessed whether NT-proBNP levels could predict the risk of moderate to severe bronchopulmonary dysplasia (BPD) and/or death. METHODS: This was an observational prospective study of preterm infants with GA ≤32 weeks. Infants who died within the first 48 h or who had major congenital malformations or incomplete information were excluded...

OBJECTIVE: In utero fetal surgery to correct incomplete closure of the spinal cord lessens the extent of permanent damage but is associated with preterm premature rupture of membranes (pPROM). We determined if compounds in amniotic fluid (AF) collected at the time of surgery predicted subsequent development of pPROM. DESIGN: Prospective study. SETTING: Hospitals in Sao Paulo, Brazil. POPULATION: Twenty four consecutive pregnant women at 24-26 weeks gestation seen between February and October 2017 with a singleton pregnancy underwent in utero surgery to correct an open spinal defect in their fetus...

Preterm neonates with respiratory distress syndrome (RDS) are at increased risk of acute kidney injury (AKI). Our study aimed at determining whether serum cystatin C (sCysC) on day 3 of life (D3) can early predict AKI in preterm neonates with RDS. This prospective study was conducted on 75 preterm neonates; 50 with RDS and 25 without RDS. On D3, sCysC, serum creatinine (sCr) and blood urea nitrogen (BUN) were measured and estimated glomerular filtration rate (eGFR) was calculated. sCr and BUN levels were measured again on days 5 and 7...

BACKGROUND: The aim of the study was to analyse body composition of preterm infants fed with either breast milk or formula compared to a control group of full-term newborns. METHODS: Fifty-three newborns were enrolled: a group of 34 very low birth weight (VLBW) preterm newborns subdivided into a formula-fed (n = 23; group A) and breast milk-fed (n = 11; group B) group, and a control group of 19 full-term infants (group C). Their body composition was assessed by a bioelectrical impedance analysis (BIA) either at the estimated time of birth in the VLBW group or during the 1st week of life in the full-term group...

The amount, composition, and sources of nutrition support provided to preterm infants is critical for normal growth and development, and particularly for structural and functional neurodevelopment. Although omega-3 long chain polyunsaturated fatty acids (LC-PUFA), and particularly docosahexanoic acid (DHA), are considered of particular importance, results from clinical trials with preterm infants have been inconclusive because of ethical limitations and confounding variables. A translational large animal model is needed to understand the structural and functional responses to DHA...

Early premature infants are subjected to many invasive procedures in neonatal intensive care units, and effective skin antisepsis is an essential step in caring for these vulnerable patients. Nevertheless, preterm infants have an anatomically and physiologically immature skin and preserving their skin integrity is essential to avoid the risk of local and systemic complications. Skin particularities of newborns reduce the list of available antiseptics in neonatology. Chlorhexidine gluconate (CHG) has excellent antiseptic properties and its antimicrobial efficacy cannot be understated, but there is great concern about its use for premature infants, referring to the risk of development skin injuries, such as skin erythema, burns, and blisters...

Preterm preeclampsia (PE), occurring at < 37 weeks' gestation, can be predicted from as early as 11-13 weeks and prevented with the use of aspirin. In contrast, term PE, which is more common than preterm-PE and it can be associated with important maternal morbidity and mortality, cannot be effectively predicted at 11-13 weeks and cannot be prevented by the prophy-lactic use of aspirin. This paper briefly reviews the pathogenesis of term PE and discusses strategies available for its prediction.

Daniel Fernández, Rebeca Antolín-Rodríguez
PROBLEM: Daily bathing of the preterm infant in the Neonatal Intensive Care Unit (NICU) is a process that is usually done routinely, but it can cause many adverse effects on the stability of the infant. Highlights include decreased body temperature and increased stress, which can cause alterations in its proper growth and development. ELIGIBILITY CRITERIA: We included both descriptive studies and analytical studies that evaluated the effects of bathing on the physiological state of the preterm infants admitted to NICU...

Preterm birth is a global health issue that can induce lifelong medical sequela. Presently, at least one in ten newborns are born prematurely. At birth, preterm newborns exhibit higher levels of oxidative stress (OS) due to the inability to face the oxygen rich environment in which they are born into. Moreover, their immature respiratory, digestive, immune and antioxidant defense systems, as well as the potential numerous medical interventions following a preterm birth, such as oxygen resuscitation, nutrition, phototherapy and blood transfusion further contribute to high levels of OS...

Preterm birth is a leading cause of long-term motor and cognitive deficits. Clinical studies suggest that some of these deficits result from disruption of cerebellar development, but the mechanisms that mediate cerebellar abnormalities in preterm infants are largely unknown. Furthermore, it remains unclear whether preterm birth and precocious exposure to the ex-utero environment directly disrupt cerebellar development or indirectly by increasing the probability of cerebellar injury, including that resulting from clinical interventions and protocols associated with the care of preterm infants...
