To examine the association between colonization by two newly classified species of genital ureaplasmas (Ureaplasma parvum and U. urealyticum) in early pregnancy and subsequent late abortion or preterm birth at <34 weeks of gestation, four species of genital mycoplasmas--Mycoplasma genitalium, M. hominis, U. parvum, and U. urealyticum--as well as Chlamydia trachomatis and Neisseria gonorrhoeae w...

OBJECTIVE To evaluate the association between gestational age at birth and the risk of subsequent development of asthma.

A total of 44,173 women delivering between 1989 and 2008 were linked with the social insurance register to ...

80% of mineral accretion take place in the third trimester of gestation with a fetal accretion rates of 100-150 mg/ kg/day for calcium, 50-70 mg/kg/day for phosphate and 3 mg/kg/day for magnesium. During the third trimester of gestation fetal weight triples but Ca content quadruples with a faster increase in fetal body Ca accretion from 32 to 40 weeks of gestation [1]. As a result, late preterm...

BACKGROUND Respiratory viral infections are a major cause of hospitalisation in infants <1 year and might cause severe symptoms in preterm infants. Our aim was to analyse admissions due to respiratory infections in moderate, late and term infants, and to identify risk factors for hospitalisation in preterm versus term. METHODS Prospective study in a cohort of moderate and late preterm, and te...

OBJECTIVE To determine whether late preterm twin neonates have a more favorable perinatal outcome than singleton late preterm neonates. METHODS We studied 401 late preterm births between 34+0 and 36+6 weeks of gestation, from January 2011 to December 2014 in our institution. We compared the maternal and neonatal characteristics and perinatal outcomes between singleton and twin pregnancies. Pe...
