CONTEXT Intrauterine growth curves are extremely useful for classifying newborn children and predicting neonatal diseases. However, such curves rely on knowledge of the gestational age, which is not always easily obtained. Therefore, the study of other anthropometric measurements and their interrelationship is always desirable, in order to attain such objectives. OBJECTIVE To evaluate whether...

This study examined the association between physical activity (PA) and bone mineral content (BMC; gram) from middle childhood to middle adolescence and compared the impact of vigorous-intensity PA (VPA) over moderate- to vigorous-intensity PA (MVPA). Participants from the Iowa bone development study were examined at ages 5, 8, 11, 13, and 15 years (n = 369, 449, 452, 410, and 307, respectively)...

OBJECTIVES To provide an updated US birth weight for gestational age reference corrected for likely errors in last menstrual period (LMP)-based gestational age dating, as well as means and SDs, to enable calculation of continuous and categorical measures of birth weight for gestational age. METHODS From the 2009-2010 US live birth files, we abstracted singleton births between 22 and 44 weeks ...

BACKGROUND Lower use of endoscopies and urgent referrals for suspected cancer has been linked to poorer outcomes for patients with cancer; it is important to examine potential predictors of variable use. AIM To examine the associations between general practice measures of patient experience and practice use of endoscopies or urgent referrals for suspected cancer. DESIGN AND SETTING Cross-se...

Methods A cross-sectional study examining parents-first-born offspring pairs. First, 200 FGR neonates (defined as birthweight < 10th according to local standards) and 200 normally grown (AGA, birthweight 10th-90th centile) were identified from delivery books from 1975-1993. Current contact data was retrieved from the database of the Catalan health system. Perinatal data from an eventual first-b...

The objective is to explore the value of preoperative magnetic resonance (MR) histogram analyses in predicting microvascular invasion (MVI) of hepatocellular carcinoma (HCC).Fifty-one patients with histologically confirmed HCC who underwent diffusion-weighted and contrast-enhanced MR imaging were included. Histogram analyses were performed and mean, variance, skewness, kurtosis, 1th, 10th, 50th...

Background: Umbilical coiling index (UCI) is the number of coils in cord divided by cordlength centimeters. .On basis UCI umbilical cords have been grouped as: hypocoiled,( UCILess than 10th percentile ) normocoiled ( between 10th–90th percentile) and hypercoiled (UCIMore 90th percentile). Various reports shown that abnormal associated withadverse perinatal outcomes.There a wide variations amon...

BACKGROUND Mean concentrations of total cholesterol (TC) among adults have declined in the United States for decades. Whether the decline has been owing to prevention of high TC levels or treatment of high TC levels once present is not known. OBJECTIVE To determine whether population-wide influences and/or the high-risk approach have been operating to produce the well-known decline in mean TC...

An extension of a regression-based methodology for constraining climate forecasts using a multi-thousand member ensemble of perturbed climate models is presented, using the multi-model CMIP-3 ensemble to estimate the systematic model uncertainty in the prediction, with the caveat that systematic biases common to all models are not accounted for. It is shown that previous methodologies for estim...
