Abnormally elevated AFP in amniotic fluid can have one or more of many different causes: [citation needed] normal elevation. 75% of AF AFP test results in the range 2.0 to 4.9 MoM are false positives: the baby is normal. open neural tube defect; open abdominal wall defect; congenital nephrosis; others
Therefore most of the effects are present to the mother through maternal viralization. [17] Most associated adverse pregnancy outcomes are due to an abnormally high observed beta-hCG levels during gestation. As a result, the subset of pregnant people in these abnormal values should be considered for enhanced surveillance.
An elevated level of stress during pregnancy leads to notorious pregnancy outcomes, including preterm birth, low birth weight, and mental health problems for the mother. Prolonged effects of chronic stressors such as discrimination, intimate partner violence, housing issues, and poverty lead to widespread maternal health issues and adverse ...
Acquired brain injury (ABI) is brain damage caused by events after birth, rather than as part of a genetic or congenital disorder such as fetal alcohol syndrome, perinatal illness or perinatal hypoxia. [1] ABI can result in cognitive, physical, emotional, or behavioural impairments that lead to permanent or temporary changes in functioning. [1]
Mothers who are negative for the Kell 1 antigen develop antibodies after being exposed to red blood cells that are positive for Kell 1.Over half of the cases of hemolytic disease of the newborn owing the anti-Kell antibodies are caused by multiple blood transfusions, with the remainder due to a previous pregnancy with a Kell 1 positive baby.
Preeclampsia, the most severe type of HDP, has been a major subject of research for scientists. Preeclampsia is usually characterized by elevated blood pressure and frequently protein in the urine after the 20th week of pregnancy, believed to be caused by abnormal placental growth leading to endothelial dysfunction and inflammation.
Polychromasia is a disorder where there is an abnormally high number of immature red blood cells found in the bloodstream as a result of being prematurely released from the bone marrow during blood formation (poly- refers to many, and -chromasia means color.) These cells are often shades of grayish-blue.
Both circulating and placental levels of soluble fms-like tyrosine kinase-1 (sFlt-1) are higher in women with pre-eclampsia than in women with normal pregnancy. [ 26 ] sFlt-1 is an anti-angiogenic protein that antagonizes vascular endothelial growth factor (VEGF) and placental growth factor (PIGF), both of which are proangiogenic factors. [ 15 ]
