A trans-abdominal USG is scheduled between 9 and 13 weeks of gestation to estimate gestational age calculated by fetal crown length. If CRL is > 95 mm, femur length and head circumference are used to assess gestational age. All digital images are taken by trained radiologists according to ...
Physical activity was summarised as metabolic equivalent hours (METhours) per week and peak oxygen uptake relative to body weight (ml/kg/min) calculated by heart rate responses. To assess the effect of gestational age on the outcomes, the adequate data were analysed by multiple linear regression...
(A) In each gestational age (week), the SGA rate is calculated by dividing the number of infants who are judged as SGA by the total number of infants born during this gestational age (week). The number of AGA infants were determined by three criteria. (B) The LGA rate is calculated ...
Our understanding of the normative concentrations of urine biomarkers in premature neonates is limited. We evaluated urine from 750 extremely low gestational age (GA) neonates without severe acute kidney injury (AKI) to determine how GA affects ten diffe
Corpus callosum segments were assessed and overall corpus callosum length was measured and plotted against the EGA for 68 anatomically normal fetal brains ranging in EGA from 18.5 to 37.7 weeks, and linear and polynomial regression models were calculated. The body of the corpus callosum was ...
Gestational age was calculated using the first day of the last menstrual period (LMP) and confirmed with sonographic dating. If the two calculations differed by less than or equal to seven days, the dating was based on the first day of the LMP. If the difference was more than seven days,...
If one uses traditional forensic anthropological sources, then age is calculated in lunar months; if one uses other sources--embryological, anthropological and sonographic--then age is reported as gestational weeks. For comparison between ages derived from these various studies, especially in cases ...
Small for gestational age was defined as < 10th percentile of growth among all infants of that gestational age; large for gestational age was defined as > 90th percentile; otherwise, infants are considered appropriate for gestational age. Ponderal index was calculated as [(birth weight; grams)/...
4,5 Ultrasound is a reliable method for establishing the length of pregnancy and in this way can improve obstetric care. METHODS OF GESTATIONAL AGE ASSESSMENT In the past gestational age was established by a combination of the historical information and the physical examination. Reliance was placed...
One hundred infants between 27 and 34 weeks gestational age assessed by maternal dates and Dubowitz Scoring were studied with the direct ophthalmoscope following dilation of the pupil. The disappearance of the anterior vascular capsule of the lens was ar
