Oyelese et al. found that 2/3 of patient with vasa previa at delivery had a low-lying placenta or placenta previa that resolved prior to the time of delivery. There are three types of vasa previa. Types 1 and 2 were described by Catanzarite et al. In Type 1, there is a velamentous insertion with vessels running over the cervix.
It is used to differentiate whether the blood coming out of vagina is of the mother or fetus during delivery i.e, placenta previa versus vasa previa. It is based on the principle that fetal HbF is resistant to acids and alkali whereas the mother's blood which has HbA is sensitive to acid and alkaline.
Vasa praevia is a very rare, presenting only 4:10,000 cases from the largest study of the condition. [16] Risks of antepartum bleeding due to vasa praevia greatly increase during the third trimester of pregnancy during cervical dilation or placenta praevia .
Type 1 diabetes (T1D), formerly known as juvenile diabetes, is an autoimmune disease that occurs when pancreatic cells (beta cells) are destroyed by the body's immune system. [5] In healthy persons, beta cells produce insulin. Insulin is a hormone required by the body to store and convert blood sugar into energy. [6]
If such vessels are identified, vasa previa may be present and cervical length is measured every week to determine the risk of premature rupture of membranes. [ 16 ] Women diagnosed with velamentous cord insertion may also receive counselling about the condition, its risks, and potential courses of action, including preterm delivery or ...
Blood glucose monitoring is the use of a glucose meter for testing the concentration of glucose in the blood ().Particularly important in diabetes management, a blood glucose test is typically performed by piercing the skin (typically, via fingerstick) to draw blood, then applying the blood to a chemically active disposable 'test-strip'.
The main goal of diabetes management is to keep blood glucose (BG) levels as normal as possible. [1] If diabetes is not well controlled, further challenges to health may occur. [1] People with diabetes can measure blood sugar by various methods, such as with a BG meter or a continuous glucose monitor, which monitors over several days. [2]
Umbilical cord abnormalities (vasa previa, multilobate including bilobate and succenturiate-lobed placentas, velamentous insertion) Other complications of pregnancy, pre-existing conditions, and concomitant disease, include: Previous (high risk) fetus
