Thompson John M D - - 2006
The rate of preterm birth in the developed world has been shown to be increasing, in part attributable to obstetric intervention. It has been suggested that this may be a differential increase between socio-economic groups. We aimed to assess whether the preterm rate in Norway is different in socio-economic groups ...

Gestational hypertension-preeclampsia is the most common medical disorder of pregnancy. It is also a major cause of maternal and perinatal morbidities. The majority of adverse pregnancy outcomes occur in patients who develop severe hypertension or severe preeclampsia, and in those who develop the clinical manifestations before 34 weeks' gestation. There ...

Determination of gestational age is important to assess risks for morbidity and mortality in neonates. Definitions for preterm, term and postterm have been precisely defined although definitions for subgroups of infants within these categories have not been well defined. More precise definitions for the subgroup of infants born "near-term" is ...

Late preterm infants (34-37 weeks gestation) pose unique challenges to physicians and nurses involved in their care after birth. They may be cared for in different units within hospitals after birth, including Neonatal Intensive Care Units, Newborn Nurseries, or rooming in with the mother. As a result of their gestational ...

Since birth-induced oxidative stress (OS) results in the removal of erythrocytes from the blood stream, we studied the binding of autologous IgG to erythrocyte band 3 dimers (the 170-kDa band, which marks the erythrocytes for removal) in preterm and term newborns and in adults. The 170-kDa band was present in ...

Metabolic bone disease is a common event in preterm infants. Between 24 wk gestation and term, the fetus accrues approximately 80% of body Ca, P and Mg. Consequently, preterm infants miss in part or completely the period of greatest mineral accretion. Ca and P requirements in preterm infants are based ...

The preterm delivery of low-birth-weight (PLBW) infants remains a significant public health issue and a leading cause of neonatal death and of long-term neurodevelopmental disturbances and health problems. Epidemiological and immunological studies have suggested that periodontal disease may be an independent risk factor for PLBW. The incidence of periodontal disease ...
