Previous randomized trials have shown that progesterone administration in women who previously delivered prematurely reduces the risk of recurrent premature delivery. Asymptomatic found at midgestation to a short cervix are greatly increased for spontaneous early preterm delivery, and it is unknown whether this such women.

To evaluate maternal and cord blood serum adropin concentrations in pregnant women with gestational diabetes mellitus (GDM).Twenty GDM 20 age-matched healthy participated the study. Maternal levels were assessed using an enzyme immunosorbent assay, at time of birth. The relation metabolic parameters also assessed.The mean group significantly lower than those control (P=0.01 P<0.001, respectively). did not correlate either fetal or values.The data suggest that low may contribute to underlying...

Abstract Objective To determine the number of scans necessary for training sonographers to examine accurately ductus venosus at 11 + 0 13 6 weeks' gestation. Methods Ten with prior extensive experience in measurement nuchal translucency thickness were given practical accurate assessment venosus. They then asked during routine scan. Each scan was assessed by an experienced sono‐ grapher and classified as being successful or unsuccessful (failure obtain a waveform, poor quality image...

Physiological and biochemical studies suggest that normal parturition at term is dependent on programmed development of the uterus in early pregnancy. It recognized a short cervix mid-pregnancy associated with an increased risk spontaneous preterm birth. We hypothesized long would be cesarean delivery during labor term.

Although progesterone given prophylactically to women with a history of preterm birth cuts the recurrence rate in half, only about 10% spontaneous early births take place such history. Because asymptomatic who have short cervix mid-gestation are at increased risk delivery, measuring cervical length by ultrasonography 20–24 weeks' gestation has been proposed as way identifying high giving before 37 gestation. In this multicenter randomized trial, was measured transvaginal 20–25 24,620...

Preterm premature rupture of membranes (PPROM) is associated with significant maternal and perinatal morbidity. This study examined oxidative stress in PPROM.This was a prospective cross-sectional conducted university hospital. A total 72 pregnant women were recruited into two groups, those PPROM (38 cases) without (34 controls) matched for gestational age. Plasma interleukin-6, C-reactive protein, vitamins C, E A, 8-isoprostane, oxidant status (TOS) antioxidant (TAS) determined all...

Abstract Aim: Evidence suggests that orexin regulates food consumption, glucose metabolism and insulin secretion. Orexin may have a role in the pathogenesis of type II diabetes mellitus, however its gestational mellitus is not known. We aimed to assess maternal serum cord blood orexin‐A (OXA) concentrations pregnant women with (GDM). Material Methods: Thirty‐five GDM 35 gestational‐age‐matched healthy subjects participated study. Maternal OXA levels were measured enzyme immunoassay at time...
