[Socio-demographic characteristics and vitamin D status in women born before 32 weeks'].

Unlabelled: Deficiency of vitamin D (25-OHD) is a health problem among prematurely born women and their newborns independently of the geographical location of the country.

Objectives: To study serum levels of vitamin D in patients born before 32 weeks and their newborns at birth. To analyse the socio-demographic factors, complications of pregnancy and their relationship with vitamin D status of women.

[Blood transfusions suppress erythropoiesis in anemia of prematurity].

Unlabelled: AIM AND TASKS: The major gene regulating erythropoietin /EPO/ synthesis is hypoxia induced factor/HIF/. Proceeding from the assumption that the transfusions /HT/ remove hypoxia due to anemia and inactivate HIF, the aim of the study was to show the decreased activity of erythropoiesis after HT MATERIALS AND METHODS:

Patients: 40 premature infants <34 g.a.

[Respirtory distress in newborns of mothers with factor V-Leiden thrombophilia].

Aim: The main aim of the trial is to determine the frequency of respiratory distress syndrome / RDS/ and disorders of coagulation in infants of mothers with thrombophilia.

Materials And Methods: In 51 newborns of mothers with thrombophilia were evaluated the presence of respiratory distress and maternal-fetal infection /MFI/. The children were divided in two groups: Group I--16 newborns of mothers with thrombophilia and Group II--15 healthy children.

[Blood lactate measurments as a diagnostic and prognostic tool after birth asphyxia in newborn infants with gestational age > or = 34 gestational weeks].

Unlabelled: Blood lactate at birth as result of activated anaerobic glycolysis is a marker of perinatal asphyxia.

Aim: To evaluate the dynamics of blood lactate, pH and base excess (BE) as a tool for assessing the severity of fetal hypoxia and predicting neonatal outcome.

Methods: 79 neonates (> or = 34 gestational weeks) were included and followed up until discharge: 43 with pathologic fetal hearth rate patterns and/or 1-minute Apgar score < 7 ("asphyxia group"); 36 without obstetric or clinical signs of asphyxia (control group).

[Problems and neonatal outcome of very low birth weight newborn infants after in vitro fertilization].

Unlabelled: The use of assisted reproduction technologies is undoubtedly successful in the treatment of sterility. However it sets up numerous of issues for the obstetricians and neonatologists.

Aims: To evaluate the incidence, the specific problems and the neonatal outcome of newborns with very low birth weight (VLBW) <1500 g born from pregnancies after in vitro fertilization (IVF).
