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.
