Hypercoagulability in pregnancyHypercoagulability in pregnancy is the propensity of pregnant women to develop thrombosis (blood clots). Pregnancy itself is a factor of hypercoagulability (pregnancy-induced hypercoagulability), as a physiologically adaptive mechanism to prevent post partum bleeding. However, when combined with an additional underlying hypercoagulable states, the risk of thrombosis or embolism may become substantial. Pregnancy-induced hypercoagulability is probably a physiologically adaptive mechanism to prevent post partum hemorrhage.
Complications de la grossesseLes complications de la grossesse sont des affections et des états pathologiques provoqués par la grossesse. Les pathologies de la grossesse sont nombreuses, en effet la grossesse est une période de vulnérabilité particulière pour la future mère et son enfant à naître. On estime qu'en France 95 % des grossesses se déroulent sans anomalie. On peut également y ajouter les maladies qui existaient avant la grossesse mais qui sont déséquilibrées par celle-ci.
Maternal physiological changes in pregnancyMaternal physiological changes in pregnancy are the adaptations that take place during pregnancy that enable the accommodation of the developing embryo and fetus. These are normal physiological adaptations that cause changes in behavior, the functioning of the heart, blood vessels, and blood, metabolism including increases in blood sugar levels, kidney function, posture, and breathing. During pregnancy numerous hormones and proteins are secreted that also have a broad range of effects.
Vertically transmitted infectionA vertically transmitted infection is an infection caused by pathogenic bacteria or viruses that use mother-to-child transmission, that is, transmission directly from the mother to an embryo, fetus, or baby during pregnancy or childbirth. It can occur when the mother has a pre-existing disease or becomes infected during pregnancy. Nutritional deficiencies may exacerbate the risks of perinatal infections. Vertical transmission is important for the mathematical modelling of infectious diseases, especially for diseases of animals with large litter sizes, as it causes a wave of new infectious individuals.
GrossesseLa grossesse, appelée aussi gestation humaine, est l'état d'une femme enceinte, c'est-à-dire portant un embryon ou un fœtus humain, en principe au sein de l'utérus, qui est dit gravide. En général, elle fait suite à un rapport sexuel, débute selon le point de vue à partir de la fécondation (fusion d'un ovule et d'un spermatozoïde) ou de la nidation (implantation de l'embryon dans l'utérus), et se déroule jusqu'à l'expulsion de l'organisme engendré.
