Objectives: This study aimed to determine the fetal philtrum length at early stages of gestation and perceive its growth through different gestational ages in case of normal and pathological fetal development. Methods: This cross-sectional observational study was conducted based on ultrasound images obtained at an institutional centre specialised in Prenatal Diagnosis. A total of 108 fetuses be...

Transvaginal sonographic measurement of cervical length, at 20 weeks of gestation, is very useful to predict spontaneous preterm birth. A large number of studies have been performed in the attempt to detect the spontaneous preterm birth on the basis of biological, biochemical and ultrasound parameters. Transvaginal Sonography is a good tool to evaluate the cervix. This study aims to evaluate th...

Seasonal endocrine changes in 5 non-bred and 10 pregnant Alaskan reindeer have been documented. Blood samples were collected from early September until early May, spanning the breeding season, gestation, or the anovulatory period. Plasma was analyzed by RIA for progesterone (P4), estradiol-17beta, estrone, and estrone sulfate. Elevated P4 in 80% of the reindeer at the onset of the study indicat...

BACKGROUND Lower levels of physical activity and cardiorespiratory fitness are key risk factors of chronic adult diseases. Physical activity and cardiorespiratory fitness are predicted by birth weight, but the underlying parental and pregnancy-related factors remain largely unknown. We examined how prenatal determinants are associated with physical activity and cardiorespiratory fitness in adol...

Using extensive international data it is shown in detail how mortality is related to birthweight and gestation. It is demonstrated that the widely used 'birthweight for length of gestation' standards can be seriously misleading. A new 'high risk' classification is proposed.
