Neurological abnormalities in full-term asphyxiated newborns and salivary S100B testing: the "Cooperative Multitask against Brain Injury of Neonates" (CoMBINe) international study.

Background: Perinatal asphyxia (PA) is a leading cause of mortality and morbidity in newborns: its prognosis depends both on the severity of the asphyxia and on the immediate resuscitation to restore oxygen supply and blood circulation. Therefore, we investigated whether measurement of S100B, a consolidated marker of brain injury, in salivary fluid of PA newborns may constitute a useful tool for the early detection of asphyxia-related brain injury.

Methods: We conducted a cross-sectional study in 292 full-term newborns admitted to our NICUs, of whom 48 suffered PA and 244 healthy controls admitted at our NICUs.

Regulation by hypoxia of adrenomedullin output and expression in human trophoblast cells.

Objectives: Plasma adrenomedullin concentrations are increased in the fetal circulation in acute and chronic hypoxic conditions. The effect of hypoxia in regulating adrenomedullin synthesis and secretion was investigated in human placental trophoblast cells.

Study Design: Human trophoblast cells obtained from term placentas (n = 7) were cultured in hypoxic condition (3% oxygen).

Intrafollicular concentration of adrenomedullin is associated with IVF outcome.

Objective: To test the hypothesis that serum or intrafollicular concentrations of adrenomedullin (AM) would correlate with reproductive outcomes in in vitro fertilisation (IVF) cycles.

Design: Serum and follicular fluid samples were collected during transvaginal oocyte retrieval. The follicular fluid was individually aspirated, and the presence of oocyte was recorded.

Biochemical markers of perinatal brain damage.

Hypoxia-ischemia constitutes a risk in infants by altering cerebral blood flow regulatory mechanisms and causing loss of cerebral vascular auto-regulation. Hypotension, cerebral ischemia, and reperfusion are the main events involved in vascular auto-regulation leading to cell death and tissue damage. These dramatic phenomena represent a common repertoire in infants complicated by perinatal acute or chronic hypoxia.

Changes in the interrelationship between leptin, resistin and adiponectin in early neonatal life.

The aim of this study was to investigate the interrelationship between leptin,adiponectin and resistin in the fetal and early postnatal period and the association of these hormones with anthropometric and metabolic indexes. Serum concentrations of leptin, adiponectin and resistin were measured in maternal and neonatal circulation at delivery and on the 3rd day after birth in 40 healthy newborns and their mothers Serum leptin levels were significantly higher in fetuses that in newborn infants on 3rd day after delivery, whereas concentration of adiponectin and resistin were maintained in either maternal and neonatal circulation after delivery. Leptin serum concentrations correlated with those of adiponectin in the fetal circulation, but not in neonatal life.

S100 beta protein is increased in fetuses with neural tube defect.

We investigated the levels of S100 beta protein (S100B) in the serum of fetuses with neural tube defects (NTD), and their mother. Samples from 20 fetuses with NTD and 30 controls at the same gestational age, and their mothers, were studied. S100B protein levels were determined using Lia-mat Sangtec.

Effect of corticosteroids and progesterone on adrenomedullin output and expression in human fetal membranes and placenta trophoblasts.

Objective: Plasma adrenomedullin (AM) concentrations are increased in fetal and maternal circulation in response to exogenous glucocorticoids administration. The role of corticosteroids and progesterone in regulating AM synthesis and secretion was investigated in amnion and chorion trophoblast cells of the fetal membranes and in placental trophoblast cells.

Study Design: Cells were treated with betamethasone, hydrocortisone, and progesterone.

New markers of neonatal neurology.

Hypoxia-ischemia (H-I) constitutes the main phenomenon responsible for brain-blood barrier permeability modifications leading to cerebral vascular auto-regulation loss in newborns. Hypotension, cerebral ischemia, and reperfusion are the main events involved in vascular auto-regulation loss leading to cell death and tissue damage. Reperfusion could be critical since organ damage, particularly of the brain, may be amplified during this period.

Objective: The aim of this study was to determine the effects of in vivo administration of prenatal betamethasone on leptin and adiponectin concentration in maternal and fetal circulation.

Study Design: Blood samples were collected from 35 pregnant women receiving betamethasone for threatened preterm delivery before and at different time points after drug administration. Cord blood was collected at delivery in infants born from mothers treated with betamethasone and in 15 infants who delivered at the same gestational age not receiving betamethasone.

Opposite effect of phorbol ester PMA on PTGS2 and PGDH mRNA expression in human chorion trophoblast cells.

Prostaglandins (PGs) induce the mechanism of labor in humans. The enzymes responsible for PG synthesis and metabolism are prostaglandin-endoperoxide synthase 2 (PTGS2) and 15-hydroxyprostaglandin dehydrogenase (PGDH). In human chorion trophoblast cells, calcium ionophore A23187 upregulates PTGS2 and downregulates PGDH protein and mRNA.

Adrenomedullin blood concentrations in infants subjected to cardiopulmonary bypass: correlation with monitoring parameters and prediction of poor neurological outcome.

Background: Brain injury is a major adverse event after cardiac surgery, especially when extracorporeal circuits are used. We evaluated whether cardiopulmonary bypass (CPB) affects cerebrovascular resistance and plasma concentrations of adrenomedullin (AM), a vasoactive peptide regulating cerebral blood flow.

Methods: We evaluated 50 infants (age <1 year) with congenital heart defects, matched according to a 2-year follow-up; 40 infants had no overt neurological injury, and 10 had brain damage.
