OBJECTIVE Serial measurements of the fetal abdominal circumference have been used to guide metabolic management of pregnancies complicated by gestational diabetes mellitus (GDM). A reduction in the number of repeat ultrasound examinations would save resources. Our purpose was to determine the number of serial abdominal circumference measurements per patient necessary to reliably predict the abs...

Performance on the psychomotor vigilance task (PVT) sensitively reflects a circadian modulation of neurobehavioral functions, as well as the effect of sleep pressure developing with duration of time awake, without being confounded by a learning curve. Sixteen healthy volunteers underwent two 40-h constant posture protocols in a balanced crossover design. During these protocols, either low sleep...

Objectives To investigate if an association exists between being born large for gestational age (LGA) and verbal ability or externalizing behaviour problems at ages 4-5 years. Method A secondary analysis was conducted using the National Longitudinal Survey of Children and Youth, including singleton births in 2004-2005 followed till 4-5 years (n = 1685). LGA was defined as a birth weight > 90t...

BACKGROUND Low birth weight (LBW) has been linked to renal disease both in animal models and human studies. However, the role of birth weight in the development of diabetic nephropathy is unclear. We, therefore, studied the impact of birth weight on the development of diabetic nephropathy and other related traits, such as diabetic retinopathy and macrovascular disease, in Caucasian type 1 diabe...

T to the massive infusion of detailed production activity data into economic study over the past couple of decades, researchers in many fields have learned a great deal about how firms turn inputs into outputs. Productivity, the efficiency with which this conversion occurs, has been a topic of particular interest. The particulars of these studies have varied depending on the researchers’ specif...

OBJECTIVE High birth weight is a risk factor for neonatal complications. It is not known if the risk differs with body proportionality. The primary aim of this study was to determine the risk of adverse pregnancy outcome in relation to body proportionality in large-for-gestational-age (LGA) infants stratified by maternal gestational diabetes mellitus (GDM). RESEARCH DESIGN AND METHODS Populat...

OBJECTIVE To examine the suitability of the growth charts that are currently used in Israel and consider their replacement with a recent standard. In a sample of schoolchildren, the current Tanner and Whitehouse standards were compared with the new growth charts from the Centers for Disease Control and Prevention (CDC). METHOD A total of 746 Israeli healthy children (368 boys and 378 girls) a...

background: the children’s body composition status is an important indicator of health condition evaluated through their body mass index (bmi). we aimed to provide standardized percentile curves of bmi in a population of iranian children and adolescents. we assessed the nationally representative of sample populations from tehran. materials and methods: a total sample of 14,865 children aged 7-1...

PURPOSE Surgical clips are used as a target for postoperative breast radiotherapy, and displacement of surgical clips would result in inaccurate delivery of radiation. We investigated the displacement range of surgical clips in the breast during postoperative radiotherapy following breast-conserving surgery. METHODS A total of 178 patients who received breast-conserving surgery and postoperat...
