Glossary
Prosthesis Definition An artificial device to replace or augment a missing or impaired part of the body.
Prosthetic Heart Valves Definition There are two basic types of artificial heart valve, mechanical valves and tissue valves. Tissue heart valves are usually made from animal tissues, either animal heart valve tissue or animal pericardial tissue. The tissue is treated to prevent rejection and to prevent calcification. Alternatives to animal tissue valves include human aortic valves called homografts. Homograft valves are donated by patients and harvested after the patient expires. The durability of homograft valves is probably the same for porcine tissue valves. Another procedure for aortic valve replacement is called the Ross procedure (after Donald Ross) or pulmonary autograft. The Ross procedure involves going to surgery to have the aortic valve removed and replacing it with the patient’s own pulmonary valve (autograft). A pulmonary homograft (a pulmonary valve taken from a cadaver) or a valvular prothesis is then used to replace the patient’s own pulmonary valve.
Prosthetics Definition The evaluation, fabrication and custom fitting of artificial limbs.
Protection Cost Definition Examples of malaria Protection Costs include expenditures on bed-nets, on spraying rooms, on mosquito coils, etc.
Protein-Energy Wasting Definition An expert panel of the International Society of Renal Nutrition and Metabolism (ISRNM) has recommended the term Protein-Energy Wasting for loss of body protein mass and fuel reserves that may occur in patients with chronic kidney disease. Protein-energy wasting is diagnosed if three characteristics are present: (1) low serum levels of albumin, transthyretin, or cholesterol, (2) reduced body mass (low or reduced body or fat mass or weight loss with reduced intake of protein and energy), and (3) reduced muscle mass (muscle wasting or sarcopenia, reduced mid-arm muscle circumference).
Proxy Definition A Proxy is a substitute decision maker, often a family member, or someone who is the most appropriate surrogate because that person ‘has loving and intimate knowledge of the subject’s wishes or values system’. The proxy serves as the patient’s representative and ideally should be chosen by the patient for this role when still able to make such a choice. Proxies customarily serve this role in the absence of a formally designated surrogate. The expectation is that proxies make health care decisions based upon substituted
