A model to predict gestational age during normal pregnancy progression was constructed; the correlation coefficient between actual and predicted weeks of gestation was 0.86. The predicted gestational ages of ca
Hypoxia is associated with pregnancy complications, such as preeclampsia, placental abruption, and gestational sleep apnea. Hypoxic insults during gestation can impact the brain maturation of cortical and subcortical pathways, such as the nigrostriatal pathway. However, the long-term effects of in utero ...
Late Preterm Pregnancy and the Newborn Assessment ofgestational ageis an imperfect science[42–45]. It typically is estimated using the mother'sLMP, or based onfetal ultrasoundmeasures[19]. When performed before 20 weeks, fetal ultrasound is considered to be more accurate than the LMP method. ...
Meconium, a non-invasive biomaterial reflecting prenatal substance accumulation, could provide valuable insights into neonatal health. However, the comprehensive protein profile of meconium across gestational ages remains unclear. Here, we conducted an e
This cohort study evaluates whether exposure to each of 3 pregnancy complications (gestational diabetes, gestational hypertension, and preeclampsia) is
Hypoxia is associated with pregnancy complications, such as preeclampsia, placental abruption, and gestational sleep apnea. Hypoxic insults during gestation can impact the brain maturation of cortical and subcortical pathways, such as the nigrostriatal pathway. However, the long-term effects of in utero...
Preexisting curves (Robinson/Fleming, Hadlock) aligned closely with the new reference curve mid-range but showed larger deviations at the extremes of assessed gestational ages. Conclusion Early pregnancy crown-rump length curves based on last menstrual period may overestimate gestational age. Using 2,...
1.The Relationship between Pregnancy Sac Size、Crown-rump Length、Serum β-hCG Level and Gestational Age in Early Pregnancy孕早期孕囊大小及头臀长、血β-hCG水平与孕龄的关系 2.Analysis of multiple obstetrical factors of neonatal asphyxia in different gestational age不同孕龄新生儿窒息的产科因素探讨 ...
Gestational age is defined as the number of weeks between date of last normal period and the date of birth [32]. Gestational age was calculated as the difference between the date of birth and the estimated date of the beginning of the pregnancy, which was provided by the mother. Then, it...
Nanoparticle exposure in pregnancy may result in placental damage and fetotoxicity; however, the factors that determine fetal nanoparticle exposure are unclear. Here we have assessed the effect of gestational age and nanoparticle composition on fetal acc
