Understanding Anemia 🍁 Anemia is a medical condition characterized by a deficiency of red blood cells or hemoglobin in the blood, which results in reduced oxygen-carrying capacity. Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to the rest of the body. Anemia can cause fatigue, weakness, shortness of breath, pale skin, and a rapid or irregular heartbeat. There are many different types of anemia, including iron-deficiency anemia, vitamin deficiency anemia, hemolytic anemia, aplastic anemia, and sickle cell anemia. The causes of anemia can also vary, and may include poor diet, chronic diseases, blood loss, and genetic factors. Treatment for anemia will depend on the underlying cause, but may involve iron or vitamin supplements, blood transfusions, or medications. ¶ Types of Anemia with explanation There are many types of anemia, each with its own specific causes and symptoms. Here are some of the most common types of anemia: • Iron-deficiency anemia:...

¶ Topic: Polycythemia and Anemia. Brookman What happens when the following blood parameters increase  and decrease in the same full blood count Test: HGB 18.4 (11-14) RBC 7.49 (2.50-5.50) HCT  52.6 (26-50.0) MCV 70.2 (86.0-110.0) MCH 24.6 (26-38.0) RDW-CV 17.2 (11.0-16.0) Suggested ways of bringing the parameters of blood cells to normal both in natural ways and the use of medicine. Thank you 🍁 Al The results you've provided show an increase in hemoglobin (HGB), red blood cell (RBC) count, and hematocrit (HCT), but a decrease in mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH). The RDW-CV value is also slightly elevated, indicating a variation in the size of the red blood cells. These results may indicate a condition called polycythemia, which means an increase in the number of red blood cells in the body. Polycythemia can be primary (when the cause is unknown) or secondary (when it's due to an underlying medical condition or medication). If...

Nursing Question 3: Sources of Vitamin B12 are: • Mushrooms, grains, nuts • Dairy products and yeast extracts • Bread, rice, broccoli and beans • All of these • None of the above Answer: Option 2 : Dairy products and yeast extracts Detailed Solution: Explanation: • It is a water-soluble vitamin and chemically known as cobalamin. • Its content in our diet is good for making red blood cells and for the formation of nerves. • It is very essential for nervous system functioning and DNA synthesis. • Sign deficiency of vitamin B12 causes tiredness, fatigue, pain in hand and feet, and also memory loss and anaemia. • High doses of it are not harmful because it is a water-soluble vitamin. Excess of it goes out of the body through urine. • Vitamin B12 keeps our nerves and bone cells healthy and also helps in making genetic material in the cell. ​Sources: Bacteria and archaea Gut microbes Yeast Milk and milk products Liver Egg Cereals Oat milk 🩸 B12 Benefits and Risks ...

What type of injury is a contusion? • Soft tissue injury • Bone injury • Luxation injury • Joint injury • Not Attempted Answer: Option 1 : Soft tissue injury ¶ Detailed Solution • Concept: The most common soft tissues to be injured are muscles, tendons, and ligaments. These injuries often occur during sports and exercise activities, but sometimes simple everyday activities can cause the injury. Sprains, strains, and contusions, as well as tendinitis and bursitis, are common soft-tissue injuries. • Important Points A bruise, also known as a contusion, is a type of hematoma of tissue in which the capillary is damaged by trauma and is the most common cause of capillary damage, leading to localized hemorrhage that engulfs the surrounding interstitial tissue. 1. A contusion injury is an injury that is not visible in our body. 2. The contusion effect falls on the internal part of the body.  3. A contusion is caused by direct blows to the body which can damage the surface and deeper tissu...

New treatments for cancer New treatments for cancer: Researchers are developing new treatments for cancer, including immunotherapy and targeted therapy. These treatments can be more effective and have fewer side effects than traditional chemotherapy. • What is Immunotherapy: Immunotherapy is a type of cancer treatment that uses the body's immune system to fight cancer. The immune system is the body's natural defense mechanism that recognizes and destroys abnormal cells, including cancer cells. However, cancer cells can sometimes evade the immune system's detection and continue to grow and spread. Immunotherapy works by stimulating the immune system to recognize and attack cancer cells. This can be done in several ways, including: • Checkpoint inhibitors: These drugs block certain proteins on the surface of cancer cells that prevent the immune system from attacking them. • CAR-T cell therapy: This treatment involves modifying a patient's o...

Guillain-Barré syndrome 🌑 Guillain-Barré syndrome, which is a rare but serious autoimmune disorder that affects the nerves and can cause muscle weakness and paralysis. In Guillain-Barré syndrome, the immune system mistakenly attacks the nerves in the body, causing inflammation and damage. This can lead to symptoms such as tingling or numbness in the hands and feet, muscle weakness, and difficulty moving or speaking. The exact cause of Guillain-Barré syndrome is not known, but it is often triggered by a viral or bacterial infection. The condition can be diagnosed through a physical examination, nerve tests, and other tests such as a spinal tap or MRI. Treatment for Guillain-Barré syndrome typically involves hospitalization and supportive care to manage symptoms, such as pain, breathing difficulties, and blood pressure changes. In some cases, intravenous immunoglobulin therapy or plasma exchange may be used to help reduce inflammation and improve symptoms. With proper treatm...
