One reason may be that your heart helps you live, by moving ~5 liters (1.3 gallons) of blood through almost 100,000 kilometers (62,000 miles) of blood vessels every single minute! It has to do this all day, everyday, without ever taking a vacation! Now that is true love. Learn about how the heart works, how blood flows through the heart, where the blood goes after it leaves the heart, and what your heart is doing when it makes the sound “Lub Dub.” About Khan Academy: Khan Academy is a nonprofit with a mission to provide a free, world-class education for anyone, anywhere.

Platelet Adhesion and Aggregation
 
04:42
Developed and produced for http://www.MechanismsInHematology.com by Mechanisms in Medicine Inc. Animation description: Platelet adhesion and aggregation. In flowing blood, red cells predominate in the axial stream, while the biconvex disc-shaped platelets are marginated along the vessel wall where they are well-positioned to monitor the integrity of the endothelium. The normal endothelium provides a non-adhesive surface to circulating platelets. However, when vessel wall injury occurs, for example, by cutting or severing of a vessel, or as shown here, by a puncture, and there is endothelial damage, the initial response of platelets is that of adhesion to collagen fibres in the exposed subendothelium. Collagen is one of the most thrombogenic components of the subendothelial matrix responsible for the initiation of platelet adhesion. A number of adhesive receptors on the platelet surface membrane interact either directly or indirectly with collagen. Initial binding of platelets is considered to occur via the integrin α2β1 (GPIa-IIa) receptor, which allows for further binding to collagen via the GPVI receptor, initiating transmembrane and, subsequently, intracellular signalling. Adhesion of platelets to the exposed subendothelium is influenced by shear rates. At high shear, α2β1 and GPVI are not sufficient to initiate binding to collagen, and binding of the GPIb-IX-V receptor to von Willebrand factor -- abbreviated here as V.W.F. -- that is immobilized on collagen, becomes essential in platelet adhesion. Platelet adhesion at the site of vessel wall damage initiates activation events that result in aggregation. Adherent platelets undergo a dramatic shape change to an irregular sphere with multiple filipodia spreading on the subendothelium increasing their area of surface contact. Adherent platelets also secrete or release the contents of their storage granules -- the alpha- and dense granules -- by an exocytic process. This provides a high local concentration of effector molecules essential for platelet plug formation at the site of vascular injury. For example, the aggregating agent A.D.P. is released from the dense granules. Platelet activation stimulates the formation of another aggregating agent, thromboxane A2 -- abbreviated here as T.X.A2 -- via the arachidonic acid cascade -- details are shown in Figure 26-5. A.D.P., thromboxane A2 and thrombin bind to specific platelet membrane receptors -- details are shown in Table 26-1 -- and stimulate aggregation on and around the platelets adherent to the subendothelium via receptor-mediated signal transduction events. Aggregation is an active metabolic process: binding of any of the agonists to their respective membrane receptors initiates signalling pathways that ultimately convert integrin αIIbβ3 -- or GPIIb-IIIa - from a low affinity resting state to a high-affinity activated state for binding extracellular soluble ligands such as plasma fibrinogen and von Willebrand factor -- fibrinogen is shown here. The transmission of an intracellular signal leads to disruption of the complex between the cytoplasmic tails of αIIbβ3, followed by a conformational change in its extracellular globular head domains from a bent to an extended state, promoting the binding to fibrinogen and von Willebrand factor. Divalent fibrinogen and multivalent von Willebrand factor function as bridges between αIIbβ3 receptors on adjacent activated platelets, thus allowing platelet aggregation to proceed. In this way, the large and complex metabolic repertoire of platelets allows them to effectively perform their primary physiological role, that of supporting hemostasis upon tissue trauma to form a platelet plug that arrests blood loss from a vascular injury.

03:31
What is Abciximab? (ReoPro) (Intravenous) Learn more: https://healthery.com/drug/abciximab-intravenous/ A platelet aggregation inhibitor used to stop platelets from causing blood clots. It is a glycoprotein IIb / IIIa receptor agonist. Abciximab is primarily used during and after invasive heart treatments, such as: Angioplasty, for artery protection to lower risk of heart attack. It prevents arteries from becoming blocked post-operation. It’s not suitable for emergency surgery because it takes 12 hours to normalize. The use of Abciximab is for patients who are undergoing coronary intervention. Its administered intravenously via bolus or drip, with a short plasma half-life. Research suggests it can be useful in the treatment of patients with: Chronic renal insufficiency, thrombus, angina and diabetes. What are the side effects? Not all side effects are serious, some may require medical attention. Most common include: blurred vision, dizziness, confusion, and weakness. Also, light-headedness, feeling faint, tiredness, excess sweating and bleeding. Usually, all side effects will subside as medication adjusts. Contact your doctor immediately if side effects worsen. Most patients will experience minimal side effects. Other side effects include: tarry, black stools, bleeding gums, and sneezing. As well as blood in stools and urine, rash, sore throat, pale skin, and fever. More include: weight gain, eye pain, chills, and unusual bleeding or bruising. Follow the prescribed dosage by your healthcare professional. In the event of an overdose contact Poison Control or the Emergency Services. Doing so can prevent serious risk of injury or death. If you take other medications be sure to tell your doctor regarding interactions. Drug interactions can cause serious complications and can even be fatal. If you've recently suffered a health problem be sure to tell you doctor. Additionally, tell you doctor if you have any addictions regarding drug use. Abciximab has been classified as a category C risk by the FDA. Such classification means it hasn't been tested regarding fetal harm. Abciximab should be stored in a refrigerator between 2C and 8C (36F to 46F). And should be destroyed if the drug is ever frozen. It is also marketed as Reopro, which is a colorless solution. It should only be used on adults and in conjunction with your medical specialist Abciximab has been used since its approval by the FDA in November 1997. Its effective in preventing clots and assists surgeons in balloon angioplasty. As well as stent placement, atherectomy and used in invasive procedures.

Lion´s mane, also known as Hericium erinaceus, is a wellknown edible and medicinal mushroom found throughout eastern Asia. Its fruiting bodies, meaning the mushroom heads, and fungal mycelia, meaning the root-like structures, exhibit various pharmacological activities, including the enhancement of the immune system as well as anti-tumor, hypoglycemic, and anti-aging properties. Scientific analysis has shown that the aromatic compounds hericenones C–H and erinacines A–I isolated from the fruiting body and mycelium promote nerve growth factor (NGF) synthesis in cultured astrocytes. These results highlight the usefulness of H. erinaceus for the treatment and prevention of dementia. However, the biochemical mechanism responsible for this action is not yet totally understood. In Japan, the fungus is known colloquially as yamabushitake, while it is called the monkey’s head mushroom in China and the lion’s mane mushroom in the US. Hericium erinaceus colonizes both living and dead broadleaf trees and is distributed around the world. This video will briefly explore some of the medically useful properties of Lion’s Mane, including its effects on nerve growth factor and cognitive function. Also I will be discussing the anti-cancer, immune-enhancing, and hypoglycemic effects of the mushroom. Finally, the effects of Lion’s Mane mushroom on platelet aggregation and its function as an antioxidant will be illuminated. Lion’s Mane Improvement of cognition To test the effects of orally administered Lion’s Mane on cognitive function, a double-blind, parallel-group, placebo-controlled trial was performed on mildly cognitively impaired 50-80 year-old Japanese men and women. A cognitive function scale based on the Revised Hasegawa Dementia Scale (HDS-R) was used. So in this study, 14 individuals received Lion’s Mane while the remaining 15 individuals received placebo (5). The researchers observed that the Lion’s Mane group increased their HDS-R score relative to controls depending on the time period when Lion’s Mane was consumed. Specifically, significant differences in cognitive function appeared at weeks 8, 12, and 16 of the trial. During the 4 week follow-up period, however, the score of the Lion’s Mane group dropped back down compared with the week 16 score (figure 1). Thus, Lion’s Mane is effective at reducing mild cognitive impairment but continuous intake may be necessary to maintain the beneficial effects of the fungus (5). Anti-cancer effect It has been demonstrated that Lion’s Mane, which primarily consists of polysaccharides, has tumor-fighting properties. However, the mechanisms by which Lion’s Mane inhibits growth of human hepatocellular carcinoma (HCC) is largely unknown. However, two studies performed by Lee et al. (8, 9) demonstrate that Lion’s Mane acts as an enhancer to sensitize apoptotic signaling mediated by doxorubicin (Dox). These findings suggest that Lion’s Mane in combination with Dox serves as an effective tool for treating drug-resistant human hepatocellular carcinoma. Immune-enhancing properties Polysaccharides are the best known and most potent mushroom-derived substances that display immuno-pharmacological properties. In a trial done by Lee et al. (9), the water soluble crude polysaccharide of lion’s mane was found to upregulate or increase macrophage (ie. White blood cell) activities, like the production of nitric oxide (NO) and the expression of cytokines. Conclusions Hericium erinaceus is a well-known edible and medicinal mushroom. Its fruiting bodies and the fungal mycelia exhibit various pharmacological properties, including factors that enhance the immune system, fight cancer, lower blood glucose, and promote nerve growth. This video reviewed evidence showing that Lion’s Mane reduces mild cognitive impairment, although continuous intake of the fungus may be necessary to maintain the beneficial effects. It has also been discovered that some hericenone compounds improve NGF. A study by Mori et al. (6) reports that Lion’s Mane contains active compounds that are not hericenones but nevertheless stimulate NGF synthesis. Even growth of adrenal nerve cells and extension of neurites were shown to be enhanced by fungus exo-biopolymers.

Rouleaux
 
00:29
Rouleaux Red blood cell (RBC) rouleaux formation is a reversible phenomenon that occurs during low blood flow and small shearing forces in circulation. Certain pathological conditions can alter the molecular constituents of blood and properties of the RBCs leading to enhanced rouleaux formation, which results in impaired perfusion and tissue oxygenation (Fayruz Kibria et. al.) Normally Blood flow is anechoic due to the size of the RBC's inability to reflect the sound waves. However when they aggregate or stack they become mobile reflectors. The flow is typically slow and sluggish. Compression of the vessel is still feasible and will clear the rouleaux momentarily. This phenomenon can be seen in a "normal" patient, however it is associated with many conditions including, malignancies, connective tissue disorders, inflammation, diabetes and pregnancy to name a few.

Platelet Rich Plasma Therapy - Everything You Need To Know - Dr. Nabil Ebraheim
 
04:57
Educational video describing the specifics of platelet rich plasm therapy. Plasma rich plasma or PRP is a volume of the plasma of autologous blood having a platelet concentration above the baseline. Platelets facilitate healing by stimulating the release of different growth factors. The growth factors recruit stem cells that facilitate healing, repair, or regeneration of the injured tissue. PRP is injected directly into injured tissue stimulating a healing response in a more powerful form. Platelets are components of blood cells. The development of PRP focuses on concentration of patient’s own blood platelets to create an active mixture of growth factors. Blood components 1-Red blood cells carry oxygen from the lungs and deliver it to the body tissues. 2-White blood cells form our immune system and help the body to fight against infection and foreign material. 3-Platelets: function of platelets: •Help in hemostasis (Stop bleeding) •Helps in the building of new tissue, act as scaffold for tissue regeneration. •Stem cell attraction and binding Platelets are directors (boss). Stem cells are the workers. Platelets divide, multiply and differentiate to become the healing cells for injured tissues. The platelets become activated by thrombin and other factors which cause a change in their morphology and the release of multiple growth factors. These growth factors bind themselves to the receptors of the cell causing intracellular changes down to the nucleus and affecting its DNA. The result is changed in the performance and function of the cell. Production of PRP •30-60 ml of the patient’s own blood is drawn from the antecubital vein. •The blood is then placed into a device to be centrifuged which separates the blood into platelet poor plasma (PPP), red blood cells (RBC) and platelet-rich plasma (PRP). •The blood is then placed in a centrifuge for 15 mins at 3,200 rpm. The centrifuge spins and separates the platelets from the rest of the blood components and increases the concentration of platelets and growth factors. The more platelet concentration, the greater the healing power. •After the centrifuge process is complete, the plasma has been separated from the blood producing the PRP. The platelet poor plasma is withdrawn and discarded. Platelet-rich plasma is withdrawn for injection. Sodium bicarbonate is used to neutralize the acidity of the sample. PRP sample has at least 4x the normal concentration of platelets needed for PRP to be effective. The more the platelet concentration the more growth factors and healing power. Ultrasound helps to deliver a concentrated sample of platelets to the injured tissue. Ultrasound increases the accuracy of delivering the sample to the injured tissue. Partial tear of the supraspinatus tendon •Injections should be performed preferably with the aid of ultrasound imaging. •Needling induced injury release thrombin which activates platelets. Platelets help in hemostasis and produce growth factors as well as chemotactic factors. •Platelets act as a scaffold for mesenchymal stem cells which start the process of tissue regeneration. •Patient typically experiences minimal to moderate discomfort which may last up to 1 weeks following the injection. •Avoid the use of anti-inflammatory medications for 6 weeks after injection.

6 Natural Blood Thinners
 
05:22
6 Natural Blood Thinners 1. Garlic Aside from giving your grandmother’s spaghetti sauce the “kick” it needs, garlic can also be good for your health. For one, it’s capable of limiting the collection of platelets, one of the primary steps in the formation of a blood clot. In small amounts, it’s unclear if garlic actually has the potential to prevent a devastating heart attack or stroke caused by a blood clot. However, in much larger amounts — such as when taken in supplement form — garlic may play a role in helping limit platelet aggregation. In short, if you’re in a position where blood clots may present a health problem, it’s a good idea to work more garlic into your diet. 2. Fish Oil There’s a good chance that, by now, you’ve heard about the health benefits of fish oil, and specifically that containing omega-3 fatty acids. These acids, which can be found in many types of fish, such as salmon, have been shown to help boost brain functionality and work against serious health problems, like stroke. But omega-3 fatty acids can also help thin the blood by preventing the formation of substances that encourage platelet formation. For people who need to be aware of the threat posed by blood clots, this makes fish oil a valuable contribution to their diet. Should you not be a fan of the taste of fish, omega-3 fatty acids can be found in supplement form. 3. Vitamin E When you were a kid, chances are your parents spent much of their time encouraging you to get all your vitamins, either through a health diet or physically taking a multivitamin. But they may not have explained that each type of vitamin is different. Take vitamin E for example. Available in a wide range of foods, including almonds, whole grains, sunflowers, eggs, seeds, and nuts, it’s been shown to help discourage the formation of blood clots and limit the chances of heart attack or stroke. Not a big fan of eggs, nuts, seeds or whole grains? Like most vitamins, vitamin E is widely available in supplement form. 4. Herbs with Coumarin There are literally hundreds of thousands of medications available to help prevent or treat serious health problems, like heart attack or stroke. But do you know where many of these medications come from? You may be surprised to hear that some, such as the medication warfarin — which is designed to help prevent blood clots — are made from easily acquired herbs. In fact, warfarin contains a compound known coumarin, which can be found in plants like angelica root, arnica flower, anise, chamomile, fenugreek, licorice root, parsley and red clover. That said, consuming these herbs may be a problem if you’re already on a blood-thinning medication like warfarin, so be sure to talk to your doctor before adding them to your diet. 5. Ginger You’ve probably heard that ginger can help reduce digestive inflammation and aid someone in overcoming mild upset stomach or indigestion, but did you know it can also help thin the blood? That’s because ginger contains salicylate, a type of acid that’s found in a few types of plants. In fact, salicylic acid is the technical name for aspirin, which can help reduce inflammation in the human body and may event assist in preventing a stroke. Ginger is readily available in root, spice or tea forms, so it’s easy to make it a regular part of your diet. Just be sure to check with your doctor to ensure it doesn’t present problems for any medications you may have been prescribed. 6. Avocado Avocado can help prevent blood clots in two ways: first, it contains omega-3 fatty acids, which have been shown to limit the formation of platelets and the development of blood clots. Second, like ginger it contains salicylate, which has also been shown to limit the chances of blood clots from forming. Avocadoes are easy to find at most grocery stores and make an excellent addition to just about any dish, from guacamole to sandwiches and salads. Just be sure to check with your family doctor to ensure it won’t interact negatively with any blood-thinning medications you may have been prescribed. See Our Another Vedeos: 1.

10 Health Benefits of Nectarines || nectarine good for diabetes || plum health benefits
 
05:51
Health Benefits Of Nectarines Antioxidant Defense Nectarines have a wonderful antioxidant power with a good amount of polyphenols, vitamin C content and carotenoids such as beta-carotene and cryptoxanthin. The skin of the nectarine fruit has a higher concentration of such components as compared to the pulp so, just wash the fruit properly and eat unpeeled. Treat Obesity Nectarines may prove useful in condition of obesity and its associated complications. Research studies have shown that stone fruits such as nectarines contain bioactive compounds such as anthocyanins, catechin, chlorogenic acid and quercitin derivatives which have the potential to combat obesity related medical conditions like diabetes and cardiac disorders. Improve vision Nectarines contains lutein, an important nutrient which encourages eye health and helps reduce the risk of a disease like age-related macular degeneration. Various investigative researches have shown that lutein is also an extremely powerful antioxidant which helps in reducing the risk of nuclear cataract. Lutein dwells in the macular pigmet of the eye and assists in protecting the retinal tissues from the damage caused by oxidative stress and high-wavelength light. In addition to this, beta-carotene present in the fruit encourages the synthesis of vitamin A and contributes in maintaining healthy eyesight and prevents diseases like blindness and xeropthalmia. Prevent Hypokalemia Nectarines contain potassium, which is essential for proper nerve and cellular function. Potassium present in stone fruits such as nectarine helps in proteins synthesis, functioning of the muscles, maintain electrolyte balance, and optimally utilize carbohydrates and supports metabolic processes. Deficit of potassium in the body may lead to disorders like hypokalemia which may degrade the muscular health and may cause cardiac arrthymia. Improve Cardiac Health Regular consumption of stone fruits such as nectarines may prove beneficial in maintaining cardiovascular health attributing to the presence of heart friendly antioxidants. Chlorogenic acid and anthocyanins present in nectarines exert inhibitory action against the oxidation of LDL cholesterol, prevents hardening of arteries and encourages proper circulation of human platelets. Flavonoids found in nectarines may help in preventing rise in the aggregation of platelets and reduce the risk of developing atherosclerosis. Prevent Cancer As stated above, nectarines contain chlorogenic acid, a natural compound which has multiple health benefits including prevention of various tumors and cancer such as colon cancer. Chlorogenic acid, as suggested by studies, possesses chemopreventive properties which inhibit the proliferation of colon carcinogenesis. Boost Immunity Inclusion of drupes such as nectarines aids in enhancing the immune defense mechanism of the body. Abundance of antioxidants such as vitamin C, zinc and other protective phenolic components in the fruit increase body’s ability to fight various infections by promoting the synthesis of antibodies. Skin Care Bioflavonoids present in the fruit contributes productively in the skin care. Anti-oxidative components such as vitamin C, lutein and beta- carotene found in nectarines take up the credit for such defensive effect. Beta-carotene, which is a precursor of vitamin A, is instrumental in exerting protective action against the skin damage caused by the exposure to UV radiations... Aid Digestion Presence of dietary fiber and alkaline nature of nectarine makes it perfect for maintaining digestive, as well as overall health. Fiber content present in nectarine absorbs water, adds bulk to the diet, regulates the bowel movements and prevents problems like gastritis, constipation and ulcers. Food for Pregnancy Expectant mothers can benefit from the vitamin and mineral treasure present in nectarines, especially the folate content, which helps in reducing the risk of neural tube defects like spina bifida, and also contributes in overall health of the mother and the baby. Abundance of potassium assists in preventing muscle cramps and keeps up the energy levels by building up the proteins. Fiber keeps up the digestive health and vitamin C content contributes in the proper growth and development of the muscles, teeth and blood vessels of the growing baby. So if you’re pregnant, the next time you feel hungry, just grab a nectarine and feel enriched! Cellular Health Nectarines contains phosphorus, an essential mineral which plays an important role in the normal functioning of cells and tissues. Phosphorus in the fruit helps in the formation of strong teeth and bones and assists in the metabolism of carbohydrates and fats. It extends its support in the cellular maintenance and repairs and also assists in renal functioning, muscular contraction, normal heart rate and nerve communication.

Will be covering Pathogensis, Clinical Signs and Symptoms, ECG and Diagnosis as well as Management Coronary Artery Disease occurs when there is an imbalance between oxygen supply of the heart with the oxygen demands of the heart. ETIOLOGY/CAUSES Decreased Oxygen supply - Atherosclerosis, Prinzmetal Angina, Arterial Thrombi, Coronary Emboli, Aortitis, Dissection Increased Oxygen Demand - Hypertrophy, Catecholamines, Tachycardia RISK FACTORS Modifiable - LDL and HDL, Hypertension, Diabetes, Obesity, Smoking Non-Modifiable - Family History, Male, Greater than 64 years old CLINICAL SIGNS AND SYMPTOMS Pain - tightness, squeezing, knot in chest, heavy weight, toothache and jaw ache, lump in the throat. Exacerbated with exertion and recumbency, sleeping. Percipitated by heavy meal, cold, sexual activity. Radiation to epigastric, shoulders down to fingers, lower jaw, subscapular space in the back. Relieved with nitroglycerin, rest. Usually occurs in the early morning due to increase sympathetic acitivity and platelet aggregation Angina Equivalent - dyspnea, nausea, fatigue. Usually seen in elderly and diabetic. PHYSICAL EXAMINATION Tachycardia and hypertensive due to pain. Auscultation may show S3/S4 or paradoxical S2 split. Levine's Sign will show clenched fist on the chest. ECG Findings Subendocardial ischemia shows ST Depression or T wave inversion. Transmural Infarct shows ST Elevation or hyperacute T wave. Pathological Q wave develops along with R wave depression. Usually takes a few hours to develop. After a few days there is a much deeper Q wave and t wave inversion. CARDIAC BIOMARKERS Troponin T and Troponin I are more specific than CKMB. Troponin peaks at 12 hours and last for weeks. CKMB rises in a 2-3 hours and goes down in 2-3 days. STRESS ECG Patient walks on treadmills while being monitored by ECG until reach 85 percent of maximum heart rate. Positive if symptoamtic, ECG changes, drop in blood pressure, ventricular tachycardia. ECHO Shows wall function and may show akinesia or hypokinesia. Used for patients with chronic angina, prior MI, pathologic Q wave and Heart Failure Electron Beam CT Calculate Calcium to calculate aggetson score which is prognostic Coronary Angiography Detects which arteries is occluded. MANAGEMENT First 10 minutes - Check for hemodynamic stability. Ask for recent bleeding neurological condition, and aortic dissection. Use of cocaine or Ergotamine (prinzmetal angina). Determine if RV or LV Infarction. Initial treatment consists of aspirin, clopidogrel, B-blocker, ACE Inhibitor, Statin, and Morphine. Nitroglycerin. Oxygen is only given if saturation is less than 94 percent. CLASSIFICATION STABLE ANGINA - Pain only at rest. Patient should be stress ECG or Echo. If positive than perform angiography. Minimize risk factors by decreasing LDL, increasing HDL, statins, beta-blockers ACUTE CORONARY SYNDROME - Constant Pain UNSTABLE ANGINA - No elevation of cardiac markers and No ST Elevation. Anti-coagulate, B-Blockers, Nitroglycerin. TIMI SCORE - Age greater than 65, Markers, ECG Changes, Risk Factors, Ischemia in 24 hours, CAD, Aspirin in last 7 days. Score of 0-4 is low risk and can be treated medically. 5-7 shoudl undergo cathetrization. NSTEMI - No ST elevation, but positive cardiac biomarkers STEMI These patients require PCI within 90 minutes. Especially if high risk. If symptoms greater than 24 hours, than fibrinolysis is ineffective because clot is too strong. FIBRINOLYSIS - not preffered due to high bleeding risk. Use aleteplate, tenecteplase. Only indicated if PCI is unavailable. If fibrinolysis doesn't work than must do rescue PCI. CORONARY ARTERY BYPASS GRAFT - Done after complicated PCI, Left main Artery involvement or three vessels involved. Severely LV ejection fraction. Or complications such as septal rupture, papillary muscle rupture and aneurysm. NON-ACUTE MANAGEMENT Continue anti-platelets - aspirin, clopidogrel Nitrates - prophylactic Anti-coagulants - risk of emboli Increase ambulation

Disseminated Intravascular Coagulation Diagnosis And Treatment
 
05:01
Disseminated intravascular coagulation, Disseminated intravascular coagulation Diagnosis, Disseminated intravascular coagulation Treatment. https://www.youtube.com/channel/UCESs38trBuiOVSf1lG-LWGw?sub_confirmation=1 In general, there is a balance between coagulation and lysis systems; In the case of disseminated intravascular coagulation, the coagulation mechanism, especially thrombin, is actively and diffuse. This can lead to thrombosis in subacute or chronic form, but more often bleeding occurs when the coagulation factors become depleted. Disseminated intravascular coagulation is characterized by evidence of thrombin and plasma activation. Disseminated intravascular coagulation is classically characterized by the concurrent appearance of generalized vascular coagulation deposition, which jeopardizes adequate blood supply to different organs and thereby contributes to organ failure. Due to the continuous activation of the coagulation system and other factors, such as altered synthesis and increased degradation of coagulation proteins and protease inhibitors, platelet excretion may occur, which may cause major bleeding in several places. In addition, high levels of fibrin degradation products may affect the function of platelets and the crosslinking of fibrin and therefore contribute to the tendency to bleed. Epidemiology The conditions arise in response to another pathology rather than as a major event. There are no predisposition factors in age, sex or race. Risk Factors Conditions that may be complicated by the spread of intravascular coagulation include: • Infections, especially septicemia, typhoid fever, rocky mountain fever and parasites. The release of meningococcal pepticemia is classical. • Malignancy, especially leukemia. • Greater trauma that includes crush syndrome and sometimes burns. • Some connective tissue diseases that include antifosfolipid syndrome. • Transfusion of incompatible blood. • Heat stroke. • Dissection of the aortic aneurysm. • Some snake bites Presentation The immediate apparent properties are usually the underlying conditions that have caused disseminated intravascular coagulation, especially if it is acute. In addition, there may be large bruises or spontaneous bleeding at the venipuncture sites, the soft palate, the legs and the trauma. In subacute or chronic disseminated intravascular coagulation, the functions may be thrombotic rather than signs of venous thrombosis. In the acute situation there are many properties that can be found: • Bleeding from at least three unrelated sites is typical and likely places include: • Ear, nose and throat • Gastrointestinal tract • Airway • Venepuncture or infusion fluid • Confusion or disorientation. • Fever. • Signs of bleeding. • Signs of anxiety disorder in adults (ARDS). • The skin can show several characters that include: • Petechia • Purple • Hemorrhagic noise • Acralcyanosis • Scalp necrosis of the lower leg (fulminating purpura) • Signs of thrombosis • Local infarction and gangways Diagnosis Blood tests can show that the number of platelets in a blood sample has decreased. Platelets are used when blood clots and blood take a long time to coagulate. The diagnosis of disseminated intravascular coagulation is confirmed if the results of the test show abnormally increased amounts of D-Dimer in plasma, a substance that releases thrombocytes when decomposed; More D-Dimer indicates that more blood clots occur than usual and often a low or decreasing level of fibrinogen. A protein consumed by blood clots. Treatment The underlying disease must be identified and corrected, whether it is an obstetric problem, an infection or a cancer. Treatment of coagulation problems when the cause is corrected. Disseminated intravascular coagulation that develops suddenly is life threatening and treated as an emergency. Platelets and coagulation factors are transfected to replace those that are depleted and stop bleeding. Heparin can be used to reduce coagulation in people who have more proliferation, more chronic intravascular coagulation, where coagulation is more of a problem than bleeding.

Top Foods To Increase Your Blood Platelets || Papaya Leaves Benefits || GIGA - Aarogya Rahasyam A low platelet count, medically known as thrombocytopenia, is a health disorder in which your blood has a lower than normal number of platelets. Platelets are the smallest of the blood cells that aid in blood clotting by forming plugs in blood vessel holes. The platelets circulate in the blood with an average lifespan of 5 to 9 days. A normal platelet count in a healthy person ranges from 150,000 to 450,000 platelets per microlitre of blood. When the count is below 150,000 per microlitre, it is considered a low platelet count. Both the papaya fruit and its leaves can help increase a low platelet count within just a few days. In 2009, researchers at the Asian Institute of Science and Technology in Malaysia found that papaya leaf juice can increase the platelet count of people diagnosed with dengue fever. Eat ripe papaya or drink a glass of papaya juice with a little lemon juice 2 or 3 times daily. You can also pound a few papaya leaves without the stalk using a pestle and mortar to extract the juice. Drink 2 tablespoons of this bitter juice 2 times a day.

Cirrhosis of the Liver Nursing Care Management Symptoms NCLEX
 
34:23
Cirrhosis of the liver nursing NCLEX review over the symptoms, nursing care/management, pathophysiology, complications, and treatments. Cirrhosis is a liver disease where liver cells become extremely damaged due to long-term/severe damage. This damage can be from a viral infection (Hepatitis B or C), heavy alcohol consumption, obesity, hyperlipidemia, bile duct problem, autoimmune etc. These damaged liver cells are replaced with fibrous tissue, and this leads to scarring of the liver. The role of the liver is to filter the blood and perform the following functions to it: metabolizing, detoxifying, storing, producing etc. When liver cells are damaged these processes do not happen. Complications of cirrhosis include: portal hypertension, splenomegaly, ascites, jaundice, hepatic encephalopathy, esophageal varices etc. All of these conditions are discussed in depth in the video. During the early stages of cirrhosis the patient may be asymptomatic, however, in the late stages the patient will have signs and symptoms that include: asterixis, fetor hepaticus, jaundice, reduced platelets and white blood cells, spider angiomas, ascites, gynecomastia, increase ammonia level etc. Nursing interventions for cirrhosis include monitoring for bleeding, abnormal glucose levels, implementing a proper diet: if patient has confusion (hepatic encephalopathy) they need a low protein diet, however, if patient isn't confused they need a high lean protein diet, low sodium, fluid restriction, assessing for rupture of varices, administering lactulose etc. Treatment for cirrhosis includes a liver transplant and medications such as diuretics, blood products, vitamin K, beta blocker or nitrates. In addition to a paracentesis. which helps remove fluid from the abdomen, if ascites is present.

Top Developments in Antiplatelet Therapy: In Acute Coronary Syndrome (H&S Clinical Update P1a)
 
26:41
Heart and Stroke Clinical Update 2015 www.heartandstroke.ca/clinicalupdate Plenary Address 1a Top Developments in Antiplatelet Therapy: Dual Oral Antiplatelet Therapy In Canadian Acute Coronary Syndrome Patients In 2015: Twice As Nice Or Double The Trouble? Presented by: Shaun Goodman, MD, MSc, FRCPC, FACC, FAHA, FESC (see below) Hilton Toronto, December 2015 Learning Objectives 1.To review the pathophysiology of acute coronary syndromes (ACS), and the pharmacokinetics and mechanism of action of acetylsalicylic acid (ASA; Aspirin™) and the adenosine disphophate receptor inhibitors (ADPris); 2. To describe the recent use of ASA and the ADPris clopiodgrel, prasugrel, and ticagrelor in ACS in Canadian hospitals; and, 3. To review and discuss the clinical trials supporting the Focused Update of the Canadian Cardiovascular Society Antiplatelet Guideline recommendations regarding the role of dual oral antiplatelet therapy in the management of ACS patients. Session Description The pathophysiology underlying most acute coronary syndromes (ACS) includes coronary artery atherosclerotic plaque rupture, ulceration, and/or erosion. This triggers platelet activation, adhesion, and aggregation with simultaneous initiation of the coagulation (clotting) cascade that occurs on the surface of activated platelets. Thus, antiplatelet therapy is pivotal to the management of patients with ACS. Based on randomized clinical trial data, current evidence-based clinical practice guidelines (including the Canadian Cardiovascular Society Antiplatelet Guideline ) recommend dual oral antiplatelet therapy with acetylsalicylic acid and an adenosine diphosphate (ADP) receptor inhibitor (ADPri; clopidogrel, prasugrel, or ticagrelor). Two recent Canadian observational studies suggest that the most commonly employed dual oral antiplatelet therapy regimen in ACS patients is ASA and clopidogrel . However, the newer ADPris prasugrel and ticagrelor have demonstrated consistent benefits over clopidogrel in clinical trials; accordingly, there have been temporal increases in ADPri use acutely and at discharge compared to previous national experience. Balancing of the benefits (e.g., myocardial infarction [MI] and stent thrombosis reduction with prasugrel and ticagrelor, mortality reduction with ticagrelor) and risks (e.g., increased risk of non-coronary artery bypass surgery [CABG]-related bleeding with prasugrel and ticagrelor) offers the potential to further improve upon the outcomes of Canadian ACS patients.

Quercetin & Vitamin C Taken Together Become More Effective Against Heart Disease, Cancer & Diabetes
 
06:28
Although quercetin is not one of the network antioxidants, it does interact with the network by regenerating vitamin C after it neutralizes a free radical, and help restore its antioxidant properties. From reducing inflammation to alleviating allergies to protecting the heart and brain, quercetin seems designed to selectively target disease and dysfunction – without dangerous side effects. By taking quercetin and vitamin C you may discover many beneficial effects. Quercetin is a powerful antioxidant, capable of scavenging harmful free radicals – such as reactive oxygen species – that can cause oxidative stress and trigger a wide variety of degenerative disease. Quercetin is a powerful anti-inflammatory agent, as inflammation has been shown to be at the root of many diseases, including cancer, this makes quercetin a powerful tool in nature’s disease-fighting arsenal. Quercetin has a time-honored place in herbal medicine, especially when it comes to allergy relief. Research has shown that quercetin inhibits the release of histamine from mast cells, thereby reducing allergy symptoms such as watery eyes, itching and hives. Quercetin not only reduces histamine levels, but also decreases the number of leukocytes in the lungs and bloodstream, relaxes smooth muscles in airway passages and restores elasticity of lung tissue. This group of benefits means it has possible applications for treating COPD and asthma. Quercetin helps it provide natural protection against heart disease. It protects cells that line the fragile walls of blood vessels, and also protects the extracellular collagen matrix from oxidation. In addition, it lowers levels of LDL cholesterol – while raising beneficial HDL. Quercetin also reduces the risk of heart attack and stroke by decreasing the “stickiness” of blood platelets. Furthermore, it stimulates production of beneficial nitric oxide, which dilates and relaxes blood vessels to enhance circulation. Quercetin not only helps prevent cancer by protecting cells from oxidative stress, inflammation and damage to DNA, but has been found to suppress the growth and spread of many different types of cancer cell lines, including cancers of the breast, lung, prostate, liver and esophagus. In a 2010 study, researchers found that a quercetin-rich diet could reduce the incidence of lung cancer in smokers by a stunning 65 percent. Quercetin mounts an all-out offensive on diabetes by improving insulin response, controlling blood sugar, reducing inflammatory markers, increasing the number of islets in the pancreas, and improving pancreatic and liver function. It also inhibits an enzyme, which contributes to diabetes complications such as peripheral neuropathy and cataracts. Quercetin enhances the activity of other antioxidant enzymes produced in the body. In particular, glutamate cysteine ligase, which is needed for the PRODUCTION OF GLUTATHIONE – the body’s ‘master antioxidant.’ Finally, quercetin can even help maintain the structure of bones. Research has shown that it can help prevent, and even reverse, bone loss and osteoporosis, while improving the micro-architecture of bone tissue. The richest sources of quercetin are found in plants of the allium family, including onions, scallions, chives, leeks, shallots and garlic. Onions are the richest source, which explains their use in folk medicine as a treatment for allergies and asthma. Quercetin is also found in many fruits, including citrus fruits, apples, cherries, grapes, tomatoes and berries. Vegetable sources include spinach, celery, potatoes, lettuce, broccoli, parsley, kale, red cabbage and green beans. Other sources include olive oil, tea, red wine, capers, lovage, sorrel and cocoa. Many herbs also contain quercetin, such as St. John’s wort, gingko biloba, hops, valerian, passionflower, and chamomile. To enhance the absorption of quercetin, natural health experts recommend taking it along with vitamin C. Before taking quercetin and vitamin C, discuss the matter with your healthcare provider, who can help you to decide what’s best for you, especially if dealing with a serious health issue. Furthermore, pectin, healthy fats, resveratrol, curcumin found inside turmeric and EGCG, from green tea can also promote quercetin absorption. Every day, research seems to reveal more of quercetin’s extraordinary range of benefits, confirming this versatile polyphenol’s position as an emerging superstar in the field of natural therapies.

Biomechanics of Blood Clotting
 
01:59
Platelets are cells in the blood whose job is to stop bleeding by sticking together to form clots and plug up a wound. Now, for the first time, scientists have measured and mapped the key molecular forces on platelets that trigger this process. The extensive results, by Emory University chemist Khalid Salaita and colleagues, are reported in two separate studies, in the Proceedings of the National Academy of Sciences and in Nature Methods: https://www.nature.com/articles/nmeth.4536 Read more about the discovery here: http://esciencecommons.blogspot.com/2017/12/new-methods-reveal-biomechanics-of.html

Ukon Turmeric( ORGANIC curcumin) with amazing Health  Benefits
 
02:43
Ukon Turmeric( ORGANIC curcumin) with amazing Health Benefits Turmeric Benefits 1. Anti-inflammatory Properties: Curcumin is an incredible anti-inflammatory agent; it influences the body’s inflammatory response by various mechanisms. One of the most powerful benefits of curcumin is its ability to inhibit the activity of NF-κB, this is a molecule that turns on multiple genes which trigger inflammation in the body. It also decreases the production of various cytokines or signaling molecules, such as TNFα, that induce an inflammatory response in the body. 2. Antioxidant Activity: When molecules interact with oxygen they can form free radicals, which are highly reactive molecules that are extremely damaging when they interact with cellular components such as DNA or the cell membrane. Curcumin is a potent antioxidant, meaning its chemical structure gives it the ability to neutralize these free radicals and ultimately reduce oxidative damage. It can also inhibit expression of iNOS, an enzyme involved with cellular damage and toxicity when there are too many free radicals in the body. 3. Orthopaedic Disorders: Curcumin’s anti-inflammatory properties reduce swelling, inflammation and pain in various joints. It has been shown to be effective for long-term treatment of osteoarthritis. It can also alleviate pain and swelling associated with rheumatoid arthritis. A clinical trial showed that curcumin was as effective as a well-known non-steroidal anti-infammatory drug (NSAID) called diclofenac in treating rheumatoid arthritis. 4. Gastrointestinal disorders: Inflammatory bowel diseases (IBD) including ulcerative colitis and Chron’s disease are normally treated with anti-inflammatory medications and immunosuppressive agents. It is a potential treatment for several gastrointestinal cancers. Infection of cells lining the GI tract by a bacterial population called H.pylori can play a key role in the initiation and progression of several gastric cancers. Curcumin has been shown to reduce the activity of H.pylori infection of epithelial cells lining the GI tract, which essentially reduces the risk of these gastric cancers. 5. Anti-carcinogenic Agent: There are three stages of carcinogenesis: initiation, promotion and progression. Curcumin has been shown to inhibit various mechanisms at all three stages of carcinogenic development! It inhibits initiation by its antioxidant and anti-inflammatory properties. Promotion is impacted by curcumin because of its ability to suppress survival and growth of cancerous cells, and induce apoptosis or programed cell-death. Curcumin inhibits cancer progression by reducing the ability for cancer cells to invade surrounding tissues and promote angiogenesis or the creation of new blood vessels. The promotion of angiogenesis would normally allow cancerous cells to spread even more! Curcumin can inhibit these mechanisms by preventing the activity of class of enzymes called MMPs; these enzymes would normally break down proteins surrounding cancer cells and provide them with extra space to proliferate and spread. Several studies have proven cucurmin to be an effective treatment for various stages of colon cancer, pancreatic cancer and many more. 6. Diabetes Management: Dietary curcumin has been shown to reduce hyperglycemia or high blood sugar and improve insulin sensitivity in type 2 diabetic rats. 7. Neurological Disorders: Various neurological disorders including Parkinson’s and Alzheimer’s disease are characterized by the formation of aggregates or clusters of protein deposits in the brain tissue. These aggregates have been shown to contribute to disease onset and progression. Curcumin has been shown to actually inhibit this protein aggregation process from happening meaning that it has neuroprotective effects! Its anti-inflammatory capabilities allow curcumin to reduce expression of inflammatory cytokines in neuronal cells, which basically protect these neurons from being damaged. It has also been shown to improve spatial memory and increase expression of genes involved with neural development in aged animal models, meaning it can improve the function of neural pathways! 8. Cardiovascular Health: Curcumin has been shown to have strong cardioprotective effects such as improved vascular endothelial function. A recent study showed that rats fed curcumin had about half the blood cholesterol as rats without curcumin. Curcumin has also been proven to be as effective at reducing cholesterol as atorvastatin or lipitor, a very well-known pharmaceutical cholesterol reducing agent. Again, curcumin can achieve the same result as atorvastin without the side effects of the drug, such as diarrhea and upset stomach! Another way in which curcumin has cardioprotective effects is that it inhibits aggregation of platelets, which basically reduces the potential for plaque formation or clots in blood vessels.
