Platelet indices in late preterm newborns.

Background: The current study objective was to compare blood platelet indices in late preterm newborns (LPN) and full term newborns (FTN).

Materials And Methods: We recruited 58 LPN and 71 FTN. Platelet indices were estimated in blood samples collected from the umbilical artery.

[Fetal activin A in labor complicated by meconium-stained amniotic fluid].

Objective: During pregnancy the placenta and the fetal membranes are the main sources of activin A. An increased level of activin A has been found in the serum of women with preeclampsia, diabetes mellitus and intrauterine growth restriction. Meconium is the predictor for adverse perinatal outcome, such as meconium aspiration syndrome or brain damage.

[Maternal serum Th1 and Th2 cytokines in preterm and term delivery].

Unlabelled: The immune system is responsible for the development of a typical pregnancy, including the induction of labor.

Objectives: The aim of our study was to determine the concentration of maternal serum Th1 and Th2 cytokines, which have opposite biological effects, in preterm and term labor.

Material And Methods: 88 patients were divided into four groups: normal pregnancy (n = 20), threatened preterm labor (n = 22), preterm delivery (n = 24) and term delivery (n = 22).

[Inflammatory mediators and hematological parameters in cord blood in labor complicated by meconium-stained amniotic fluid].

Objective: Meconium-stained amniotic fluid at term gestation is a predictor for adverse perinatal outcome and is associated with increased peripartum infections, independent of other risk factors. The aim of our study was to evaluate concentrations of inflammatory mediators (such as cytokine IL-6 and intracellular adhesion molecule ICAM-1) and values of hematological parameters of cord blood in presence or absence of meconium in amniotic fluid in term labor.

Material And Methods: Cord blood samples were obtained from 66 term normal neonates immediately after birth, Soluble ICAM-1 and IL-6 concentrations were measured with ELISA R&D Systems kits.

[Biophysical and biochemical intrapartum fetal assessment in relation to hematological varaiables in umbilical cord blood].

Unlabelled: The analysis of the hematological variables of umbilical cord blood can be useful in broadening our knowledge of both physiological and pathological processes undergoing during prenatal period.

Objectives: The aim of our study was to evaluate the hematological parameters of umbilical cord blood in cases of either the abnormal fetal heart rate or the confirmed fetal acidosis.

Material And Methods: A study group consisted of 458 neonates, live-born term of 38 to 41 completed weeks of single gestation.

Influence of perinatal factors on hematological variables in umbilical cord blood.

Objective: The purpose of our study was to investigate any possible relationship between the duration of labor, the mode of delivery and the duration of rupture of membranes and hematological parameters in cord blood.

Material And Methods: We studied 298 pregnant women who delivered term normal infants. The patients were divided into three groups according to the route of delivery: vaginal (n = 165), cesarean section after labor (n = 27) and elective cesarean section (n = 106).

Expression of estrogen receptors alpha and beta in term human myometrium.

We used immunohistochemistry to compare the expression of estrogen receptors (ERalpha and ERbeta) in term myometria of 32 pregnant women divided in two groups. Group I comprised of 16 women in labour and group II included 16 non-laboring gravidas. We observed cytoplasmatic localization of both ER isoforms and no differences in the ER expression between the two groups of patients.

[Retroperitoneal hematoma during pregnancy--diagnostic dilemma].

A 43-year old gravida 4, para 3 woman in 22 weeks of gestation was admitted because of severe upper abdominal pain. On arrival at the hospital a complete blood cell count showed anemia with hemoglobin concentration of 9.3 g/dl.

[Cord blood reticulocytes and reticulocyte subtypes in normal and complicated pregnancy].

Reticulocyte analysis using flow cytometry increases the precision of reticulocyte enumeration and can evaluate the maturation of reticulocytes. Reticulocytes count and their subtypes may reflect function of hematopoesis, especially during hypoxia. This study was aimed to establish reticulocyte count and reticulocyte maturation profile in cord blood during normal pregnancy and pregnancy complicated by chronic intrauterine hypoxia.
