American Society For Apheresis
The American Society for Apheresis (ASFA) is an organization of physicians, scientists, nurses, and allied health professionals whose mission is to advance apheresis medicine for patients, donors and practitioners through education, evidence-based practice, research and advocacy. ASFA represents a broad range of health care professionals involved in apheresis medicine including those practicing pathology, transplantation, hematology, oncology, neurology, rheumatology, nephrology, hepatology, gastroenterology, cardiology, and ophthalmology. These health care providers are involved in the performance of therapeutic apheresis procedures including plasma exchange, red cell exchange, leukocytapheresis, plateletapheresis, photopheresis, LDL apheresis, and hematopoietic progenitor cell collection. ASFA also represents those physicians and allied health professionals involved in the collection of blood products from blood donors using apheresis instruments. The major activities of ...

Physician
A physician (American English), medical practitioner (Commonwealth English), medical doctor, or simply doctor, is a health professional who practices medicine, which is concerned with promoting, maintaining or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients, and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines, such as anatomy and physiology, underlying diseases and their treatment—the ''science'' of medicine—and also a decent competence in its applied practice—the art or ''craft'' of medicine. Both the role of the physician and the meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plasma Exchange
Plasmapheresis (from the Greek πλάσμα, ''plasma'', something molded, and ἀφαίρεσις ''aphairesis'', taking away) is the removal, treatment, and return or exchange of blood plasma or components thereof from and to the blood circulation. It is thus an extracorporeal therapy, a medical procedure performed outside the body. Three general types of plasmapheresis can be distinguished: * ''Autologuous'', removing blood plasma, treating it in some way, and returning it to the same person, as a therapy. * ''Exchange'', a patient's blood plasma is removed, while blood products are given in replacement. This type is called plasma exchange (PE, PLEX, or PEX) or plasma exchange therapy (PET). The removed plasma is discarded and the patient receives replacement donor plasma, albumin, or a combination of albumin and saline (usually 70% albumin and 30% saline). * ''Donation'', removing blood plasma, separating its components, and returning some of them to the same person, while hol ...

Certification
Certification is the provision by an independent body of written assurance (a certificate) that the product, service or system in question meets specific requirements. It is the formal attestation or confirmation of certain characteristics of an object, person, or organization. This confirmation is often, but not always, provided by some form of external review, education, assessment, or audit. Accreditation is a specific organization's process of certification. According to the U.S. National Council on Measurement in Education, a certification test is a credentialing test used to determine whether individuals are knowledgeable enough in a given occupational area to be labeled "competent to practice" in that area. Types One of the most common types of certification in modern society is professional certification, where a person is certified as being able to competently complete a job or task, usually by the passing of an examination and/or the completion of a program of stu ...

Blood Cell
A blood cell, also called a hematopoietic cell, hemocyte, or hematocyte, is a cell produced through hematopoiesis and found mainly in the blood. Major types of blood cells include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). Together, these three kinds of blood cells add up to a total 45% of the blood tissue by volume, with the remaining 55% of the volume composed of plasma, the liquid component of blood. Red blood cells Red blood cells or ''erythrocytes'', primarily carry oxygen and collect carbon dioxide through the use of hemoglobin. Hemoglobin is an iron-containing protein that gives red blood cells their color and facilitates transportation of oxygen from the lungs to tissues and carbon dioxide from tissues to the lungs to be exhaled. Red blood cells are the most abundant cell in the blood, accounting for about 40-45% of its volume. Red blood cells are circular, biconcave, disk-shaped and deformable to allow them to squee ...

Society Of Hemapheresis Specialists
A society is a group of individuals involved in persistent social interaction, or a large social group sharing the same spatial or social territory, typically subject to the same political authority and dominant cultural expectations. Societies are characterized by patterns of relationships (social relations) between individuals who share a distinctive culture and institutions; a given society may be described as the sum total of such relationships among its constituent of members. In the social sciences, a larger society often exhibits stratification or dominance patterns in subgroups. Societies construct patterns of behavior by deeming certain actions or concepts as acceptable or unacceptable. These patterns of behavior within a given society are known as societal norms. Societies, and their norms, undergo gradual and perpetual changes. Insofar as it is collaborative, a society can enable its members to benefit in ways that would otherwise be difficult on an individual b ...

Webinar
Web conferencing is used as an umbrella term for various types of online conferencing and collaborative services including webinars (web seminars), webcasts, and web meetings. Sometimes it may be used also in the more narrow sense of the peer-level web meeting context, in an attempt to disambiguate it from the other types known as collaborative sessions. The terminology related to these technologies is exact and agreed relying on the standards for web conferencing but specific organizations practices in usage exist to provide also term usage reference. In general, web conferencing is made possible by Internet technologies, particularly on TCP/IP connections. Services may allow real-time point-to-point communications as well as multicast communications from one sender to many receivers. It offers data streams of text-based messages, voice and video chat to be shared simultaneously, across geographically dispersed locations. Applications for web conferencing include meetings, tra ...

Blood Donation
A blood donation occurs when a person voluntarily has blood drawn and used for blood transfusion, transfusions and/or made into biopharmaceutical medications by a process called Blood fractionation, fractionation (separation of whole blood components). Donation may be of whole blood, or of specific components directly (apheresis). Blood banks often participate in the collection process as well as the procedures that follow it. Today in the developed world, most blood donors are unpaid volunteers who donate blood for a community supply. In some countries, established supplies are limited and donors usually give blood when family or friends need a transfusion (directed donation). Many donors donate for several reasons, such as a form of charity, general awareness regarding the demand for blood, increased confidence in oneself, helping a personal friend or relative, and social pressure. Despite the many reasons that people donate, not enough potential donors actively donate. Ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LDL Apheresis
In medicine, LDL apheresis is a form of apheresis, resembling dialysis, to eliminate the cholesterol-containing particle low-density lipoprotein (LDL) from the bloodstream. Uses It is used in diseases featuring high LDL, such as the rare ''homozygous'' familial hypercholesterolemia, when the ''heterozygous'' form does not respond to medical treatment, or when the treatment has led to dangerous side-effects (such as rhabdomyolysis). The procedure takes 2–4 hours and must be repeated every several weeks to keep the LDL levels from accumulation and causing cardiovascular disease. It is an expensive procedure, limiting its use to severe cases of hyperlipidemia. Principles LDL apheresis works by leading venous blood through a column containing beads coated with antibodies to apolipoprotein B (the main protein of LDL particles), dextran sulfate cellulose beads, modified polyacrylate beads, or by precipitating LDL Low-density lipoprotein (LDL) is one of the five major groups ...

Photopheresis
__NOTOC__ In medicine, photopheresis (''aka'' extracorporeal photopheresis or ECP) is a form of apheresis and photodynamic therapy in which blood is subject to apheresis to separate buffy coat ( WBC + platelets) from whole blood, chemically treated with 8-methoxypsoralen (instilled into a collection bag or given per os in advance), exposed to ultraviolet light (UVA), and then returned to the patient. Activated 8-methoxypsoralen crosslinks DNA in exposed cells, ultimately resulting apoptosis of nucleated cells. The photochemically damaged T-cells returned to the patient appear to induce cytotoxic effects on T-cell formation. The mechanism of such “antitumor” action has not been elucidated. A 1987 New England Journal of Medicine publication introduced photopheresis involving 8-methoxypsoralen., now standard U.S. Food and Drug Administration (FDA) therapy for cutaneous T-cell lymphoma. Evidence suggests that this treatment might help treat graft-versus-host disease, thoug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plateletpheresis
Plateletpheresis (more accurately called thrombocytapheresis or thrombapheresis, though these names are rarely used) is the process of collecting thrombocytes, more commonly called platelets, a component of blood involved in blood clotting. The term specifically refers to the method of collecting the platelets, which is performed by a device used in blood donation that separates the platelets and returns other portions of the blood to the donor. Platelet transfusion can be a life-saving procedure in preventing or treating serious complications from bleeding and hemorrhage in patients who have disorders manifesting as thrombocytopenia (low platelet count) or platelet dysfunction. This process may also be used therapeutically to treat disorders resulting in extraordinarily high platelet counts such as essential thrombocytosis. Platelet transfusion Platelet transfusions are traditionally given to those undergoing chemotherapy for leukemia, multiple myeloma, those with aplastic a ...
