BACKGROUND Cervical incompetence is an important cause of miscarriage and premature birth and polycystic ovary syndrome is a heterogeneous endocrine disorder that is the most common cause of anovulatory infertility and eugonadotrophic hypogonadism. By now, it is still debated whether women with PCOS have an increased risk of miscarriage and there have been no studies about the pregnancy outcome...

to describe and compare the clinical outcome of infants born to mothers with gestational and pregestational diabetes mellitus, this study was conducted between january 2000 to january 2002 in tehran vali-e-- -asr hospital. among 4472 deliveries, we found 107 infants born to diabetic mothers out of whom 6 were twins. the prevalence of diabetes in total deliveries was 2.39%. mean age of gestation...

OBJECTIVE The aim of this study was to develop birth weight references for twins. Mean birth weights of individual twins are lower than those of singletons, hence singleton birth weight curves may not be suitable to assess twin birth weights. STUDY DESIGN Twin birth weight curves were developed according to gestational age, gender, parity and mode of -conception. The curves are based on popul...

AIM To examine the association of birth parameters with biometry and refraction in Singapore Chinese schoolchildren. METHODS Chinese children aged 7-9 years (n = 1413) from three schools in Singapore were recruited. Birth parameter information on birth weight, head circumference, length at birth, and gestational age were obtained from standard hospital records. Cycloplegic autorefraction, ker...

Low birth weight is frequently associated with a disproportionately high incidence of cardiovascular disease, diabetes mellitus, and kidney disease in adulthood. Epidemiological studies have identified an inverse association between low birth weight or being small for gestational age and hypertension in adulthood. We hypothesized that children born with low birth weight might have altered circa...

Background: Birth weight and gestational age are two important variables in obstetric research. The primary measure of gestational age is based on a mother’s recall of her last menstrual period. This recall may cause random or systematic errors. Therefore, the objective of this study is to utilize Bayesian mixture model in order to identify implausible gestational age.   Methods: ...

OBJECTIVE To evaluate trends and reproductive outcomes of gestational surrogacy in the United States. DESIGN Retrospective cohort study. SETTING Infertility clinics. PATIENT(S) IVF cycles transferring at least one embryo. INTERVENTION(S) Use of a gestational carrier. MAIN OUTCOME MEASURE(S) Trends in gestational carrier cycles during 1999-2013, overall and for non-U.S. residents; repr...

PURPOSE To study the association between maternal smoking during pregnancy and low birth weight (LBW), small-for-gestational-age birth weight (SGA) and preterm birth, and to quantify the population-attributable fractions for these outcomes in Switzerland. METHODS Data were gathered for all births in the Canton of Vaud (Switzerland) over a twelvemonth period in 1993-1994. LBW was defined as bi...

The incidence of pregnancy related diabetes has been steadily increasing during the past decade. The aim of this retrospective study was to evaluate the type and prevalence of gestational diabetes complications after implementing new diagnostic criteria for gestational diabetes. The incidence of gestational diabetes, maternal age, mode of delivery and birth weight were analyzed. Study patients ...

INTRODUCTION Gestational diabetes has been associated with obesity later in life. However, reported results have not been consistent and the methods used have shown weakness. OBJECTIVE To analize prospective and retrospective cohort studies that assess the gestational diabetes effects on adiposity indicators in the offspring during their first 18 years. METHODOLOGY A search was made for pro...
