The second factor is the failure to detect donor blood containing these infectious agents, even when screening of the donor blood is done (Kitchen & Barbara, 2008).
The first factor is based on the fundamental need in allogeneic blood transfusion to make sure that the appropriate infectious pathogens are screened for in the donor blood. Universal screening uses the thumb rule that all donations be screened for the viral agent's hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV) and the bacterial agent responsible for syphilis (Treponema pallidum). This raises the issue of the remaining infectious agents like those responsible for Chagas disease and human T-cell lymphotropic virus. Many such infectious agents are not geographically widespread and are restricted to certain continents, regions or countries in the world. Thus their presence is not universal restricting the need for universal screening of these infectious agents. The additional screening policy for infectious should be based on the relevant prevalence of these infectious agents narrowed down to the donor population in the country or region (Kitchen & Barbara, 2008).
The second factor is an even more critical issue in infectious risks of allogeneic blood transfusion. The failure to detect an infectious blood donation in the screening program may arise from several reasons of human error to biological variability. While failure to detect infectious blood donation due to scientific or biological variability is difficult to remove, failure to detect infectious blood donation from human error is manageable through well-developed and managed blood transfusions. ...Download file to see next pagesRead More

Blood pressure

...?Blood pressure is a measure of tension exerted by blood against the walls of the arteries. It de s the force of ventricular contraction, the resistance within the arterioles and the capillaries and the volume and viscosity of blood. Accurate measurement of blood pressure in the presence of findings in the history and physical examination of a patient can bring to light a diagnosis that may pertain to any of the above factors. This is why measurement of blood pressure is an integral part of general as well as cardiovascular examination. There are several processes that control the blood pressure. The two most important mechanisms are a baroreceptor mechanism and a rennin-angiotensin-aldosterone system. The baroreceptor mechanism works...

Adverse Effects of Blood Transfusions

...? Adverse Effects of Blood Transfusions (Add (Add (Add Adverse Effects of Blood Transfusions Medical dictionaries define blood transfusion as the process of transferring blood or blood based products from an individual to the circulatory system of another. “Blood transfusion is the transfer of blood from the vein of one person (donor) to the vein of another (recipient); and this includes collection of blood from the donor and administration of blood to the recipient” (Thresyamma, 2005). Generally, blood transfusion is conducted to replace the blood lost from a person’s body due to a surgery or a serious injury. This technique is also used when an individual’s body is not capable of producing blood due to illness. A small needle is used...

Compare and discuss the advantages and disadvantages of the different sources of haemapoietic stem cells in transplantation

Stem cell transplantation can be defined as a process by which stem cells from the patient or a donors bone marrow are removed and re-infused into the patient to produce healthy blood cells (Australian Academy of Science, 2001). Stem cell transplants may be allogeneic, syngeneic or autologous. The most common sources for such transplants are bone marrow, blood and umbilical cord or placental stem cells (Gross & Johnson, 1998. )
Bone marrow transplantation (BMT) is a procedure wherein the bone marrow, which has been destroyed subsequent to chemotherapy or radiation, is replaced with healthy bone marrow. Peripheral blood stem cell transplantation (PBSCT) involves replacing blood-forming cells destroyed by cancer treatment wi...

Blood Diamonds

...Blood Diamonds The expression ‘conflict’ or ‘blood diamonds’ describes renegade armed militias in certain regions of Africa who control the extraction and export of unregulated diamonds and use the profits to finance armed campaigns. These ‘conflicts’ have resulted in the slaughter, torture and rape of an untold number of innocent civilians and has led to the displacement of millions. This discussion profiles the ‘blood diamond’ industry and the problems it creates then concludes with suggestions to alleviate this horrific humanitarian catastrophe. Diamonds are commonly associated with glamour, love and affluence but the discovery that they were financing conflicts in Sierra Leone, The Congo, Liberia and Angola took the ‘shine off...

Cllinical Skils in haematology and bone marrow transplantion Nursing Module

... for allogeneic bone marrow transplantation (BMT). This is important because such patients have a lower risk of graft rejection if transfusion with blood products is minimized prior to transplantation. Urgent referral of such patients to a transplant center is essential. Unless transplantation is excluded as an option, all patients should be given cytomegalovirus (CMV) seronegative blood products until their CMV immune status is known. Seronegative transplant candidates should continue to receive CMV seronegative blood. This is done because CMV can cause serious infections following BMT. All blood products must be leukocyte reduced and irradiated in potential BMT recipients to minimize allosensitization and eliminate the potential risk...

Anatomy of the Blood and Blood Pressure

...Anatomy 1. In your own words, describe how blood flows through veins and how blood flow relates to blood pressure. Then, give an example of a time when one might have irregular blood pressure and how this affects blood flow. We learn from our biology class that blood flows through the veins due to the pumping action of the heart. So, when the heart performs its function of pumping blood through the arteries which uses pressure , there is a certain amount of resistance that small arterioles exert when receiving blood from the bigger arteries . This tension between the pressure of blood flow and the resistance of the arteries determines the blood pressure. Certain qualities of the arteries ( such as elasticity ) that carry...

Blood composition

... Teacher’s Institute BLOOD COMPOSITION Blood is the basic body fluid. It is the fluid that flows through the vessels and maintainsthe circulatory function among the body systems. Blood serves major functions owing to its composition. Blood is composed of plasma and three types of cells: Red cells, white cells and the platelets. Plasma is the fluid part and serves as the transport medium. The cells are formed in the bone marrow from the pluripotent stem cells. These cells are unique as they have the ability to differentiate into any of the hematopoietic cell lineages. They either divide into lymphoid stem cells or myeloid stem cells. The latter are responsible for giving rise to the blood cells. The mixed myeloid progenitor cells...

Blood Cholesterol/Blood Pressure

... Article Relationship between weight loss and blood pressure In a report that was issue by the world health organization, 2002. It was found that there is a growing prevalent of those with chronic diseases occasioned by obesity. In was also contained in the report that a close correlation do exist between the being obese and developing high blood pressure (Krueger, 2012). Unfortunately, there is no known cure for high blood pressure thought it can be prevented or controlled. It is therefore construable that with diminishing body weight, one significantly reduces the possibility of developing high blood pressure. The relationship of body weight and blood pressure are directly proportional. This statement should though be taken...

Blood Pressure

...Insert Introduction During the laboratory activity, systolic blood pressure (the maximum pressure exerted by the blood against the artery walls) of the test subject was 110 at rest. However, this pressure increased to 120 and 140 when subject was placed under 1kg and 2.5 kg workloads respectively. This was the case as blood flow has to increase during strenuous activity (exercise) in order to supply nourishment (oxygen and nutrients) to critical organs such as the heart, brain, lungs and muscles. At the same time, diastolic pressure (the lowest pressure in the artery) at rest was measured at 70 but decreased to 50 then 40 at 1 kg and 2.5 kg workloads respectively. Diastolic pressure is a result of ventricular diastole or relaxation...

Blood

... Origins of blood types There are no less than 3 hypotheses regarding the emergence as well as transmutation of human blood types. Human blood types evolution is as old as human history. Worldwide distribution pattern of blood types is dependent on different environmental factors like climate, disease, humidity and altitude. In 1900, Karl Landsteiner made a discovery. According to him, some blood transfusions are successful while others are dangerous missions. Landsteiner also discovered particularly the ABO blood group by mixing some of his cells and mature serum in every one of their staff. He also proved that some people’s red blood cells agglutinated. Landsteiner also came up with 3 new ways of thinking and identified existence 3 kinds...
