The normal pattern of cerebral asymmetry may be altered in neurodevelopmental disorders such as autism and schizophrenia. Babies born very preterm have an increased risk of brain damage, and brain abnormalities which persist into adolescence. This study aimed to ascertain whether preterm birth affects the development of fronto-occipital asymmetry. Structural ...

A substantial number of prematurely born infants will experience later neurodevelopmental challenges. Abnormal development of the cerebellum may be related to some of the impairments exhibited by preterm children. To test the hypothesis that cerebellar development is structurally impaired in preterm infants and associated with adverse outcomes, we studied 83 ...

The aim of this study is to review the normal development of the intestinal microflora of preterm infants and the factors influencing its development. Preterm infants have an increased intestinal permeability, which may lead to bacterial translocation to systemic organs and tissues. In combination with immaturity of the immune system ...

In Western countries, 5-11% of all infants are born before 37 weeks of gestation, and with improvements in modern intensive care techniques the number of these preterm infants that survive continues to increase. Preterm birth is one of the leading causes of neonatal morbidity and mortality in developed countries, accounting ...

Spontaneous preterm labour and delivery accounts for approximately one-third of preterm births, which is the predominant cause of perinatal mortality and morbidity. This review aims to evaluate the evidence on the benefits and harms of five classes of tocolytic therapy, namely: betamimetics, calcium channel blockers, magnesium, non-steroidal anti-inflammatory agents, and ...
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 ...

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 ...
