Current treatment is replacement of the missing
blood clotting factor by transfusing commercially prepared factor concentrates.
Researchers simulating conditions of reduced cabin pressure and reduced oxygen levels such as may be encountered during an 8-hour aeroplane flight, found no increase in the activation of the
blood clotting system among healthy individuals, according to a study in the May 17 issue of JAMA (Journal of the American Association).
The study of
blood clotting was published by The Lancet, a medical journal.
Physicians often advise patients not to use painkillers such as aspirin and ibuprofen in the week or so before a planned surgery because those drugs inhibit
blood clotting and can increase the risk of serious bleeding in the operating room.
Entitled The contraceptive conundrum, it lists common side-effects, including nausea, headaches, vomiting, weight gain, vaginal or bladder infections and, the most serious of all, abnormal
blood clotting. Blood clots associated with those who take the pill occur in the veins of the legs and are called thromboembolisms, from which some women experience ongoing health problems, and three percent of women die.
This project will determine whether
blood clotting factor homologues are expressed in fiber type-specific muscle exposed to the atrophy of simulated microgravity.
Anticoagulants are agents that prevent
blood clotting.
Symptoms that have been reported by women using synthetic HRT are: vaginal bleeding, abnormal
blood clotting, gallbladder disease, pancreatitis, liver problems, headaches, depression, dizziness, pulmonary problems, nausea, vomiting, cramps, jaundice, weight changes, loss of libido and edema.
