Normally, ovine placental mass increases until about day 70 of gestation, [45] but high demand on the placenta for fetal growth occurs later. (For example, research results suggest that a normal average singleton Suffolk x Targhee sheep fetus has a mass of about 0.15 kg at day 70, and growth rates of about 31 g/day at day 80, 129 g/day at day ...
If small for gestational age babies have been the subject of intrauterine growth restriction, formerly known as intrauterine growth retardation, [5] the term "SGA associated with intrauterine growth restriction" is used. Intrauterine growth restriction refers to a condition in which a fetus is unable to achieve its genetically determined ...
Specific chromosomes: The influence of CPM on fetal growth is chromosome specific. Certain chromosomes carry imprinted genes involved in growth or placental function, which may contribute to impaired pregnancy progress when CPM is detected. [7] Different chromosomes are observed at different frequencies depending on the type of CPM observed. [2]
Intrauterine hypoxia (also known as fetal hypoxia) occurs when the fetus is deprived of an adequate supply of oxygen. It may be due to a variety of reasons such as prolapse or occlusion of the umbilical cord , placental infarction , maternal diabetes (prepregnancy or gestational diabetes ) [ 1 ] and maternal smoking .
Tocolytics are used in preterm labor, which refers to when a baby is born too early before 37 weeks of pregnancy. As preterm birth represents one of the leading causes of neonatal morbidity and mortality, the goal is to prevent neonatal morbidity and mortality through delaying delivery and increasing gestational age by gaining more time for other management strategies like corticosteroids ...
His manual dexterity at procedures and the Rodeck-Nicolaides team soon produced important papers on the use of fetoscopy in the management of a wide range of conditions such as Rhesus iso-immunization, fetal hydrops and intrauterine growth restriction, and procedures such as blood and tissue sampling in the diagnosis of single gene defects. [4]
Fetal cells from the bone marrow go to the tumor sites where they may have tissue repair functions. [53] Microchimerism of fetomaternal cell trafficking origin might be associated with the pathogenesis or progression of cervical cancer. Male cells were observed in patients with cervical cancer but not in positive controls.
Fetal warfarin syndrome is a disorder of the embryo which occurs in a child whose mother took the medication warfarin (brand name: Coumadin) during pregnancy. Resulting abnormalities include low birth weight , slower growth , intellectual disability , deafness , small head size , and malformed bones , cartilage , and joints .
