Transfusion Medicine
Transfusion medicine (or transfusiology) is the branch of medicine that encompasses all aspects of the transfusion of blood and blood components including aspects related to hemovigilance. It includes issues of blood donation, immunohematology and other laboratory testing for transfusion-transmitted diseases, management and monitoring of clinical transfusion practices, patient blood management, therapeutic apheresis, stem cell collections, cellular therapy, and coagulation. Laboratory management and understanding of state and federal regulations related to blood products are also a large part of the field. Overview In most countries, immunohematology and transfusion medicine specialists provide expert opinion on massive transfusions, difficult/incompatible transfusions and rational use of specialised blood product therapy like irradiated blood/ leukodepleted/washed blood products. The blood donor center is the facility that collects blood components from screened blood dono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blood Transfusion
Blood transfusion is the process of transferring blood products into a person's circulation intravenously. Transfusions are used for various medical conditions to replace lost components of the blood. Early transfusions used whole blood, but modern medical practice commonly uses only components of the blood, such as red blood cells, white blood cells, plasma, clotting factors and platelets. Red blood cells (RBC) contain hemoglobin, and supply the cells of the body with oxygen. White blood cells are not commonly used during transfusion, but they are part of the immune system, and also fight infections. Plasma is the "yellowish" liquid part of blood, which acts as a buffer, and contains proteins and important substances needed for the body's overall health. Platelets are involved in blood clotting, preventing the body from bleeding. Before these components were known, doctors believed that blood was homogeneous. Because of this scientific misunderstanding, many patients died b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transfusion Practitioner
A transfusion practitioner (TP ''"Tee Pee"'', also known as Transfusion Nurse, Transfusion Safety Officer, Haemovigilance Officer, PBM Practitioner and PBM Nurse) is one with a critical role to play in developing a culture of transfusion safety, appropriateness, and Patient Blood Management (PBM) within healthcare establishments. The role is undertaken by a range of healthcare professionals, with many having nursing or science qualifications. The work of the TP varies across countries and in organisations, some are sole practitioners and others work as part of a team. Much of their work involves ensuring current clinical practices align with state, national, and international guidelines and standards. Transfusion Practitioners improve transfusion practice by promoting safe transfusion practice in a variety of ways. The varied activities of the TP can include: * transfusion education to clinical colleagues * providing transfusion information for patients and families * risk managemen ...

Pathology
Pathology is the study of the causes and effects of disease or injury. The word ''pathology'' also refers to the study of disease in general, incorporating a wide range of biology research fields and medical practices. However, when used in the context of modern medical treatment, the term is often used in a narrower fashion to refer to processes and tests that fall within the contemporary medical field of "general pathology", an area which includes a number of distinct but inter-related medical specialties that diagnose disease, mostly through analysis of tissue, cell, and body fluid samples. Idiomatically, "a pathology" may also refer to the predicted or actual progression of particular diseases (as in the statement "the many different forms of cancer have diverse pathologies", in which case a more proper choice of word would be " pathophysiologies"), and the affix ''pathy'' is sometimes used to indicate a state of disease in cases of both physical ailment (as in cardiomy ...

Creutzfeldt–Jakob Disease
Creutzfeldt–Jakob disease (CJD), also known as subacute spongiform encephalopathy or neurocognitive disorder due to prion disease, is an invariably fatal degenerative brain disorder. Early symptoms include memory problems, behavioral changes, poor coordination, and visual disturbances. Later symptoms include dementia, involuntary movements, blindness, weakness, and coma. About 70% of people die within a year of diagnosis. The name Creutzfeldt–Jakob disease was introduced by Walther Spielmeyer in 1922, after the German neurologists Hans Gerhard Creutzfeldt and Alfons Maria Jakob. CJD is caused by a type of abnormal protein known as a prion. Infectious prions are misfolded proteins that can cause normally folded proteins to also become misfolded. About 85% of cases of CJD occur for unknown reasons, while about 7.5% of cases are inherited in an autosomal dominant manner. Exposure to brain or spinal tissue from an infected person may also result in spread. There is no evid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scottish National Blood Transfusion Service
The Scottish National Blood Transfusion Service (SNBTS) is the national blood, blood product and tissue provider. It makes up a Strategic Business Unit of NHS National Services Scotland (NSS). History The first dedicated transfusion service in Scotland was formed at the Royal Infirmary of Edinburgh in the 1930s. The Edinburgh Blood Transfusion Service (EBTS) was established in 1936 with Jack Copland as Organiser and Helen White as Secretary. Helen White took over as Organiser in 1940 when Copland moved into a national role. The first meeting of the Scottish National Blood Transfusion Associsation (SNBTA) took place in Edinburgh in February 1940. Key personnel In the 1940s Helen White played a key role in the development of the blood donor service in Edinburgh and throughout Scotland, on her initiative a network of voluntary organisers was established. The network was characterised by its friendliness and the care she took in making voluntary donation an enjoyable activity. ...

Effective Use Of Blood
Effectiveness is the capability of producing a desired result or the ability to produce desired output. When something is deemed effective, it means it has an intended or expected outcome, or produces a deep, vivid impression. Etymology The origin of the word "effective" stems from the Latin word effectīvus, which means creative, productive or effective. It surfaced in Middle English between 1300 and 1400 A.D. Usage In mathematics and logic, ''effective'' is used to describe metalogical methods that fit the criteria of an effective procedure. In group theory, a group element acts ''effectively'' (or ''faithfully'') on a point, if that point is not fixed by the action. In physics, an effective theory is, similar to a phenomenological theory, a framework intended to explain certain (observed) effects without the claim that the theory correctly models the underlying (unobserved) processes. In heat transfer, ''effectiveness'' is a measure of the performance of a heat exchanger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serious Hazards Of Transfusion
Serious Hazards of Transfusion (SHOT) is the United Kingdom's haemovigilance scheme. It collects and analyses anonymized information on adverse events and blood transfusion reactions. When SHOT has identified risks related to transfusion, it produces recommendations within its annual reports to improve patient safety. These reports are freely available on its website. SHOT, together with the Medicines and Healthcare products Regulatory Agency (MHRA), works to support haemovigilance reporting in the UK. Results SHOT's statistical data has been used to decrease bacterial infections through better skin cleansing procedures and the incidence of life-threatening transfusion-related acute lung injury (TRALI) in the UK, by discouraging the use of fresh frozen plasma from female donors. The cause of TRALI is not fully understood, and may have more than one mechanism, but most cases are associated with transfusion of plasma or other blood products that contain some antibodies that the ...

Hematology
Hematology ( always spelled haematology in British English) is the branch of medicine concerned with the study of the cause, prognosis, treatment, and prevention of diseases related to blood. 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 (thrombus), other bleeding disorders, and blood cancers such as leukemia, multiple myeloma, and lymphoma. The laboratory analysis of blood is frequently performed by a medical technologist or medical laboratory scientist. Specialization Physicians specialized in hematology are known as hematologists or haematologists. Their routine work mainly includes the care and treatment of patients with hematological diseases, although some may also work at the hematology laboratory viewing blood films and bone marrow slides under the ...

Australian Red Cross Blood Service
Australian Red Cross Lifeblood, simply known as Lifeblood, is a branch of the Australian Red Cross responsible for the collection and distribution of blood and biological products in Australia. Lifeblood employs around 3,700 employees across scientific, clinical and support services, processing over half a million blood donations each year. Lifeblood is primarily funded by the Australian Government and state and territory governments. History The Red Cross' Australian blood services were initially managed by state-level organisations. Victoria's Blood Transfusion Service was founded in 1929 by Hematologist Lucy Meredith Bryce, who was the founding director from 1929 to 1954 of the then Victorian Red Cross, and by 1941 each state had its own Organ Transfusion Service. Also in 1941, the National Emergency Blood Transfusion Service (later the National Blood Transfusion Committee) was formed to coordinate the state groups. In 1945, the Red Cross took over blood and serum prepara ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ABO Blood Group System
The ABO blood group system is used to denote the presence of one, both, or neither of the A and B antigens on erythrocytes. For human blood transfusions, it is the most important of the 43 different blood type (or group) classification systems currently recognized by the International Society of Blood Transfusions (ISBT) as of June 2021. A mismatch (very rare in modern medicine) in this, or any other serotype, can cause a potentially fatal adverse reaction after a transfusion, or an unwanted immune response to an organ transplant. The associated anti-A and anti-B antibodies are usually IgM antibodies, produced in the first years of life by sensitization to environmental substances such as food, bacteria, and viruses. The ABO blood types were discovered by Karl Landsteiner in 1901; he received the Nobel Prize in Physiology or Medicine in 1930 for this discovery. ABO blood types are also present in other primates such as apes and Old World monkeys. History Discovery The ABO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karl Landsteiner
Karl Landsteiner (; 14 June 1868 – 26 June 1943) was an Austrian-born American biologist, physician, and immunologist. He distinguished the main blood groups in 1900, having developed the modern system of classification of blood groups from his identification of the presence of agglutinins in the blood, and in 1937 identified, with Alexander S. Wiener, the Rhesus factor, thus enabling physicians to transfuse blood without endangering the patient's life. With Constantin Levaditi and Erwin Popper, he discovered the polio virus in 1909. He received the Aronson Prize in 1926. In 1930, he received the Nobel Prize in Physiology or Medicine. He was posthumously awarded the Lasker Award in 1946, and has been described as the father of transfusion medicine. Early life and education Born into a Jewish family, Landsteiner's father, Leopold (1818–1875), a renowned Viennese journalist who was editor-in-chief of ''Die Presse'', died at age 56, when Karl was only 6. This led to a close ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
