AIM The aim of this study was to investigate long-term cognitive outcome in a cohort of 18-year-olds born preterm and previously assessed at the age of 5.5. METHODS We tested 134 adolescents born preterm with a very low birthweight of <1500 g and 94 term-born controls with a comprehensive cognitive battery at 18 years of age. The cohort was subdivided into 73 extremely preterm, 42 very preter...

S chaaf and colleagues 1 have confirmed an increased risk of preterm birth in singleton pregnancies among women with a history of preterm birth in a twin pregnancy. Their comprehensive evaluation of a large dataset should settle the uncertainty that has attended previous smaller studies. 2-6 The risk is real, so now the question is, Why? Why do women who deliver twins preterm more often deliver...

BACKGROUND Preterm birth is a major risk factor for morbidity and mortality among infants worldwide, and imposes considerable burden on health, education and social services, as well as on families and caregivers. Morbidity and mortality resulting from preterm birth is highest among early (< 28 weeks gestational age) and moderate (28-32 weeks) preterm infants, relative to late preterm infants (...

OBJECTIVE Recent studies have shown that from the postconceptional age of 33 weeks, preterm infants are able to memorize tactile information about the shape of an object by using their hands, and can detect differences with another shape. This study aimed to investigate tactile abilities earlier on in development, in very preterm and mildly preterm human infants. METHODS Infants were assigned...

Preterm birth, a major determinant of infant mortality, has been increasing in recent years. The authors examined trends in preterm birth and its determinants by using the US birth and infant death files for 1989-1997. The impact of trends in preterm birth rates on neonatal and infant mortality was also evaluated. Among Whites, preterm births (<37 completed weeks of gestation) increased from 8....

BACKGROUND Folic acid-containing multivitamins have been associated with a reduced risk of preterm birth. We examined whether periconceptional use of folic acid alone reduced this risk. METHODS Data were derived from a large population-based cohort study conducted in China to evaluate the prevention of neural tube defects with folic acid supplementation. The sample comprised 207 936 singleton...

BACKGROUND The objective of this study was to investigate the relationship between history of induced abortion and preterm delivery in various parts of Europe, and according to the main cause of preterm birth. METHODS We used data from a case-control survey, the EUROPOP study; 2938 preterm births and 4781 controls at term from ten European countries were included. Based on national statistics...

background: since preterm delivery is an important problem in obstetrics, it is necessary to know the risk factors. periodontal disease is an infectious disease and infection is risk factor for preterm delivery. respecting to the mechanisms of preterm delivery and because involved mediators in this procedure are synthesized in periodontal disease, gum disease is investigated as risk factor for ...

objective(s): we aimed to investigate the influence of transient receptor potential channel 3 (trpc3) on lipopolysaccharide-induced (lps) preterm delivery mice. materials and methods: mice were randomly assigned to the four groups: an unpregnant group, a mid-pregnancy group (e15), a term delivery group, and an lps-induced preterm delivery group (intraperitoneal injection lps at 15 days). uterin...

prematurity is the most common cause of neonatal death. risk factors of premature birth can be related with ethnicity and genetic. there is no comprehensive high sample size study in kurdish ethnicity to determine risk factors related to prematurity. this study evaluated risk factors of preterm labor in kurdish ethnicity.this case-control study was conducted in 200 preterm infants (case group) ...
