Answer the following question: Information:  - Coagulopathy ( also called a clotting disorder ) is a condition in which the blood 's ability to coagulate ( form clots ) is impaired . This condition can cause a tendency toward prolonged or excessive bleeding ( bleeding diathesis or bleeding disorder ) , which may occur spontaneously or following an injury or medical and dental procedures .  - In medicine (hematology), bleeding diathesis (h(a)emorrhagic diathesis) is an unusual susceptibility to bleed (hemorrhage) mostly due to hypocoagulability, in turn caused by a coagulopathy (a defect in the system of coagulation). Several types are distinguished, ranging from mild to lethal. Also, bleeding diathesis can be caused by thinning of the skin or impaired wound healing.  - Hematology, also spelled haematology (from the Greek , "haima" "blood," and -o), is the branch of medicine concerned with the study, diagnosis, treatment, and prevention of diseases related to blood. Hematology includes the study of etiology. It involves treating diseases that affect the production of blood and its components, such as blood cells, hemoglobin, blood proteins, bone marrow, platelets, blood vessels, spleen, and the mechanism of coagulation. Such diseases might include hemophilia, blood clots, other bleeding disorders and blood cancers such as leukemia, myeloma, and lymphoma. The laboratory work that goes into the study of blood is frequently performed by a medical technologist or medical laboratory scientist. Many hematologists work as hematologist-oncologists, also providing medical treatment for all types of cancer.   - Medicine (British English ; American English ) is the science and practice of the diagnosis, treatment, and prevention of disease. The word "medicine" is derived from Latin "medicus", meaning "a physician". Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.    Given the information, choose the subject and object entities that have the relation of 'medical specialty'.
