Recombinant FVIIa
Recombinant factor VIIa (rfVIIa) is a form of blood factor VII that has been manufactured via recombinant technology. It is administered via an injection into a vein. It is used to treat bleeding episodes in people who have acquired hemophilia, among other indications. The most common side effects with Novoseven include venous thromboembolic events (problems caused by blood clots in the veins), rash, pruritus (itching), urticaria (hives), fever and reduced effectiveness of treatment. The most common side effects with Cevenfacta include injection site discomfort and hematoma (a collection of blood under the skin) as well as injection-related reactions, an increase in body temperature, dizziness and headache. Novoseven was approved for medical use in the European Union in February 1996, and in the United States in March 1999. Medical uses Novoseven is indicated for the treatment of bleeding episodes and for the prevention of bleeding in surgical interventions or invasive p ...

Intravenous Injection
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein. The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth. It may also be used to administer medications or other medical therapy such as blood products or electrolytes to correct electrolyte imbalances. Attempts at providing intravenous therapy have been recorded as early as the 1400s, but the practice did not become widespread until the 1900s after the development of techniques for safe, effective use. The intravenous route is the fastest way to deliver medications and fluid replacement throughout the body as they are introduced directly into the circulatory system and thus quickly distributed. For this reason, the intravenous route of administration is also used for the consump ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haemophilia A
Haemophilia A (or hemophilia A) is a blood clotting disorder caused by a genetic deficiency in clotting factor VIII, thereby resulting in significant susceptibility to bleeding, both internally and externally. This condition occurs almost exclusively in males born to carrier mothers due to X-linked recessive inheritance. Nevertheless, rare isolated cases do emerge from de novo (spontaneous) mutations. The medical management of individuals with hemophilia A frequently entails the administration of factor VIII medication through slow intravenous injection. This intervention aims to address and preempt additional bleeding episodes in affected individuals. Signs and symptoms Haemophilia A's phenotype has a quite wide range of symptoms encompassing both internal and external bleeding episodes. Individuals with more severe haemophilia tend to experience more intense and frequent bleeding, whereas those with mild haemophilia typically exhibit milder symptoms unless subjected to sur ...

Iraq War
The Iraq War (), also referred to as the Second Gulf War, was a prolonged conflict in Iraq lasting from 2003 to 2011. It began with 2003 invasion of Iraq, the invasion by a Multi-National Force – Iraq, United States-led coalition, which resulted in the overthrow of the Ba'athist Iraq, Ba'athist government of Saddam Hussein. The conflict persisted Iraqi insurgency (2003–2011), as an insurgency arose against coalition forces and the newly established Iraqi government. US forces Withdrawal of United States troops from Iraq (2007–2011), were officially withdrawn in 2011. In 2014, the US became re-engaged in Iraq, leading a new coalition under Combined Joint Task Force – Operation Inherent Resolve, as the conflict evolved into the ongoing Islamic State insurgency in Iraq (2017–present), Islamic State insurgency. The Iraq invasion was part of the Presidency of George W. Bush, Bush administration's broader war on terror, launched in response to the September 11 attacks. ...

Boxed Warning
In the United States, a boxed warning (sometimes "black box warning", colloquially) is a type of warning that appears near the beginning of the package insert for certain prescription drugs, so called because the U.S. Food and Drug Administration specifies that it is formatted with a "box" or border around the text to emphasize its importance. The FDA can require a pharmaceutical company to place a boxed warning. It is the strongest warning that the FDA requires, and signifies that medical studies indicate that the drug carries a significant risk of preventable, serious or even life-threatening adverse effects. Economists and physicians have thoroughly studied the effects of FDA boxed warnings on prescription patterns. It is not necessarily true that a physician and patient will have a conversation about a drug's boxed warning after it is issued. For instance, an FDA-mandated boxed warning decreased rosiglitazone use by 70%, but that still meant 3.8 million people were given th ...

Side Effect
In medicine, a side effect is an effect of the use of a medicinal drug or other treatment, usually adverse but sometimes beneficial, that is unintended. Herbal and traditional medicines also have side effects. A drug or procedure usually used for a specific effect may be used specifically because of a beneficial side-effect; this is termed " off-label use" until such use is approved. For instance, X-rays have long been used as an imaging technique; the discovery of their oncolytic capability led to their use in radiotherapy for ablation of malignant tumours. Frequency of side effects The World Health Organization and other health organisations characterise the probability of experiencing side effects as: * Very common, ≥ 1⁄10 * Common (frequent), 1⁄10 to 1⁄100 * Uncommon (infrequent), 1⁄100 to 1⁄1000 * Rare, 1⁄1000 to 1⁄10000 * Very rare, < 1⁄10000 The |
Coagulation
Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a thrombus, blood clot. It results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair. The process of coagulation involves Platelet-activating factor, activation, Cell adhesion, adhesion and aggregation of platelets, as well as deposition and maturation of fibrin. Coagulation begins almost instantly after an injury to the endothelium that lines a blood vessel. Exposure of blood to the subendothelial space initiates two processes: changes in platelets, and the exposure of subendothelial Tissue factor, platelet tissue factor to coagulation factor VII, which ultimately leads to cross-linked fibrin formation. Platelets immediately form a plug at the site of injury; this is called ''primary hemostasis. Secondary hemostasis'' occurs simultaneously: additional coagulation factors beyond factor VII (#Coagulation factors, listed below) respond in a c ...

Intracerebral Hemorrhage
Intracerebral hemorrhage (ICH), also known as hemorrhagic stroke, is a sudden bleeding into Intraparenchymal hemorrhage, the tissues of the brain (i.e. the parenchyma), into its Intraventricular hemorrhage, ventricles, or into both. An ICH is a type of bleeding within the skull and one kind of stroke (ischemic stroke being the other). Symptoms can vary dramatically depending on the severity (how much blood), acuity (over what timeframe), and location (anatomically) but can include headache, Hemiparesis, one-sided weakness, numbness, tingling, or Hemiplegia, paralysis, speech problems, vision or hearing problems, memory loss, attention problems, coordination problems, balance problems, dizziness or Presyncope, lightheadedness or vertigo, nausea/vomiting, seizures, decreased level of consciousness or Unconsciousness, total loss of consciousness, neck stiffness, and fever. Hemorrhagic stroke may occur on the background of alterations to the blood vessels in the brain, such as cer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arterial Thrombosis
Thrombosis () is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system. When a blood vessel (a vein or an artery) is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss. Even when a blood vessel is not injured, blood clots may form in the body under certain conditions. A clot, or a piece of the clot, that breaks free and begins to travel around the body is known as an embolus. Thrombosis can cause serious conditions such as stroke and heart attack. Thrombosis may occur in veins (venous thrombosis) or in arteries ( arterial thrombosis). Venous thrombosis (sometimes called DVT, deep vein thrombosis) leads to a blood clot in the affected part of the body, while arterial thrombosis (and, rarely, severe venous thrombosis) affects the blood supply and leads to damage of the tissue supplied by that artery (ischemia and necrosis). A piece of either an arterial or a venous thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glanzmann's Thrombasthenia
Glanzmann's thrombasthenia is an abnormality of the platelets. It is an extremely rare coagulopathy (bleeding disorder due to a blood abnormality), in which the platelets contain defective or low levels of glycoprotein IIb/IIIa (GpIIb/IIIa), which is a receptor for fibrinogen. As a result, no fibrinogen bridging of platelets to other platelets can occur, and the bleeding time is significantly prolonged. Signs and symptoms Characteristically, there is increased mucosal bleeding: * heavy menstrual bleeding * easy bruising * nosebleeds * Bleeding from the gums * gastrointestinal bleeding * postpartum bleeding * increased postoperative bleeding. The bleeding tendency is variable but may be severe. Bleeding into the joints, particularly spontaneous bleeds, are very rare, in contrast to the hemophilias. Platelet numbers and morphology are normal. Platelet aggregation is normal with ristocetin, but impaired with other agonists such as ADP, thrombin, collagen, or epinephrine. Cause G ...

Factor VII Deficiency
Factor VII deficiency is a bleeding disorder characterized by a lack in the production of Factor VII (FVII) (proconvertin), a protein that causes blood to clot in the coagulation cascade. After a trauma factor VII initiates the process of coagulation in conjunction with tissue factor (TF/factor III) in the extrinsic pathway. The condition may be inherited or acquired. It is the most common of the rare congenital coagulation disorders. Signs and symptoms Symptoms may differ greatly, as apparently modifiers control to some degree the amount of FVII that is produced. Some affected individuals have few or no symptoms while others may experience life-threatening bleeding. Typically this bleeding disorder manifests itself as a tendency to easy bruising, nose bleeding, heavy and prolonged menstruation, and excessive bleeding after dental or surgical interventions. Newborns may bleed in the head, from the umbilicus, or excessively after circumcision. Other bleeding can be encountered in ...
