OBJECTIVES The concentration of bioavailable insulin-like growth factor (IGF) I and II is important to foetal growth. It is regulated by insulin-like growth factor binding proteins (IGFBP) 1 through 6. Proteolytic cleavage of IGFBP-3 takes place in human pregnancy serum; accordingly, IGFBP-3 serum levels decrease markedly during pregnancy. ADAM12 (A(More)
Listeria is commonly found in processed and prepared foods and listeriosis is associated with high morbidity and mortality. Preventative measures are well prescribed and monitoring and voluntary recall of contaminated products has resulted in a 44% reduction in the prevalence of perinatal listeriosis in the USA. Pregnant women are at high risk for(More)
OBJECTIVE To investigate the association between elective caesarean sections and neonatal respiratory morbidity and the importance of timing of elective caesarean sections. DESIGN Cohort study with prospectively collected data from the Aarhus birth cohort, Denmark. SETTING Obstetric department and neonatal department of a university hospital in Denmark.(More)
Connective tissue in biopsy specimens taken from the lower part of the uterine cervix in 40 pregnant women at various gestational ages was compared to that in similar biopsy specimens from 15 nonpregnant women. The concentrations of collagen, sulfated glycosaminoglycans, and hyaluronic acid decreased during pregnancy. At the gestational age of 10 weeks, the(More)
BACKGROUND During normal pregnancy the cervix has a load bearing function. The cervical tissue consists mainly of an extracellular matrix (ECM) rich in collagen; important for the biomechanical properties. The aim of the present study was to evaluate how the biomechanical strength of samples from the distal cervix is associated with collagen content in(More)
OBJECTIVE The cervical mucus plug is positioned between the microbe-rich vagina and the normally sterile uterine cavity, which suggests a host defense function, but few relevant data are available. We analyzed the composition and antimicrobial activity of cervical mucus plugs. STUDY DESIGN Cervical mucus plugs were collected from healthy women at(More)
When postpartum cervical biopsy specimens were compared with biopsy specimens from nonpregnant women, they revealed a 12-fold decrease in mechanical strength, a 50% reduction in the concentrations of collagen and sulfated glycosaminoglycans, a 35% reduction in hyaluronic acid, an increase in collagen extractability, and a fivefold increase in collagenolytic(More)
OBJECTIVE The purpose was to determine the concentration of leukocyte elastase and SLPI in the cervical mucus plug, cervical tissue, fetal membranes, amniotic fluid and serum from pregnant women. STUDY DESIGN Samples were analysed using radioimmunoassay, immunodiffusion, immunohistological and enzyme assay techniques. Statistical comparisons were(More)
OBJECTIVE Neutrophil elastase (NE), a multifunctional serine protease stored in azurophilic granules of mature neutrophils, is capable of intracellular degradation of proteins during phagocytosis and extracellular degradation of connective tissue during an inflammatory process. Secretory leukocyte protease inhibitor (SLPI) is a natural NE inhibitor present(More)
OBJECTIVE Electrohysterographic assessment of the propagation velocity of uterine depolarization has been introduced as a promising predictor of preterm labor. Therefore, the objectives of this study were to characterize the uterine electrohysterographic signals during labor and to determine the propagation velocity and propagation direction of(More)
