Advance Planning Health care professionals should discuss the importance of advance directives with competent patients. Although organ donation is a difficult topic to bring up near the time of death, potential donors can be assured that their gift could greatly enhance or save the lives of others. Treatments that maintain the viability of organs and tissues cannot be used if they may harm the donor. Sometimes the care of a donor and the needs of a potential recipient may appear to be in conflict, but the care of donors and recipients is always kept separate and performed by different physicians. Advance directives are incorporated into the medical record and updated when appropriate. They take effect only if a physician determines that a patient lacks the ability to understand and make decisions about available treatments. Living wills can include detailed instructions about life-sustaining procedures that a person does or does not want. Another important directive is a durable power of attorney (sometimes called a health care proxy), in which another person (a health care agent) is appointed to act as decision maker in the event of incapacitation. Only one person can be designated, although one or two alternates may also be listed. If an agent is given comprehensive power to supervise care, he or she may make decisions about medical staff, health care facilities, and medical procedures. Some states restrict the use of advance directives to terminal illness or disallow them if a woman is pregnant. State statutes also specify characteristics of people who may serve as health care agents and witnesses. Ongoing Issues Despite the availability of advance directives, only about 20 percent of people in the United States have completed one. Physicians must often make treatment decisions before they have a chance to discuss them with patients or caregivers. Patients who are fully aware of treatment options and clearly state their preferences are more likely to be successful at obtaining the care they desire. Medical decisions that are planned in advance and discussed with close friends and family can help to prevent decision-making dilemmas during emergency situations. Health practitioners should strive to provide the best information possible so that patients can consider all of the medical options available and make their preferences known to medical personnel.

Many patients with severe stress require life support measures and intensive monitoring. Stress also raises nutritional needs considerably- increasing the risk of malnutrition even in previously healthy individuals. Providing nutrition care for these patients is not only challenging; it is often ineffective for preventing weight loss and muscle tissue losses. Despite these difficulties, the health care professional must determine the best measures to take in order to limit damage and promote recovery. Later sections of this chapter describe respiratory stress, which is characterized by inadequate oxygen and excessive carbon dioxide in the blood and tissues. Both metabolic and respiratory stress can lead to hypermetabolism (above-normal metabolic rate), wasting (breakdown of muscle mass and loss of strength), and in severe circumstances, life-threatening complications. The highlight following this chapter discusses the causes and consequences of multiple organ dysfunction syndrome, the simultaneous dysfunction of two or more organ systems, which is often fatal. Metabolic stress is characterized by changes in metabolic rate, heart rate, blood pressure, hormonal status, and nutrient metabolism. Energy is of primary importance, and therefore the energy nutrients are mobilized from storage and made available in the blood.
Diseases
Peripheral neuropathy precludes repetitive weight-bearing exercises such as jogging and step exercises hair loss kidney disease purchase 0.5 mg dutasteride, because these activities may lead to foot ulcerations hair loss real cure purchase dutasteride 0.5 mg with amex. The use of protective foot gear hair loss cure date order 0.5 mg dutasteride with mastercard, such as gel soles or air midsoles and socks that prevent blisters hair loss cure for dogs cheap dutasteride 0.5 mg overnight delivery, can help to prevent foot trauma. Hence, individuals with diabetes are counseled about sick-day management along with other self-care measures for diabetes. During illness, patients with diabetes should measure blood glucose levels and ketone levels in blood or urine several times daily. They should continue to take antidiabetic medications, including insulin, as prescribed. If over-the-counter drugs are necessary, they should use only those that are sugar- and alcohol-free. Because some medications (such as decongestants) needed during illness can raise blood glucose levels and others (such as medications that contain aspirin) can interact with oral antidiabetic drugs, patients should check with health care providers before using an unfamiliar drug. If appetite is poor, they should choose easy-to-manage foods and beverages that provide the prescribed amount of carbohydrate at each meal. Foods that are easily tolerated include toast, crackers, soup, yogurt, fruit, fruit juices, frozen juice bars, and carbohydrate-sweetened beverages. To prevent dehydration, especially if vomiting or diarrhea are present, liquids should be ingested in adequate amounts throughout the day. Glycemic control is most often evaluated by monitoring blood glucose levels and glycated hemoglobin. Carbohydrate intake is the main factor that influences blood glucose levels after meals. The total amount of carbohydrate ingested is more important than the type of carbohydrate consumed. Carbohydrate counting is widely used in menu planning and can be taught at different levels of complexity, depending on individual needs and abilities. Insulin therapy is required for patients who are unable to produce sufficient insulin and may be used in both type 1 and type 2 diabetes. Various medications can improve insulin secretion and effectiveness, suppress glucagon secretion, reduce glucose production by the liver, and delay carbohydrate absorption. Physical activity can improve glycemic control and enhance various aspects of general health. The Case Study provides an opportunity to review the factors that influence treatment for a 12-year-old with type 1 diabetes. Diabetes Management in Pregnancy Women with diabetes face new challenges during pregnancy. Due to hormonal changes, pregnancy increases insulin resistance and the need for insulin, so maintaining glycemic control may be more difficult. In addition, up to 7 percent of nondiabetic women develop gestational diabetes and require treatment during pregnancy. She practices intensive therapy and has had the support of her parents and an excellent diabetes management team. With their help, Nora has been able to assume the bulk of the responsibility for her diabetes care and has managed to control her blood glucose remarkably well. In the last few months, however, Nora has been complaining bitterly about the impositions diabetes has placed on her life and her interactions with friends. Sometimes she refuses to monitor her blood glucose levels, and she has skipped insulin injections a few times. Recently, Nora was admitted to the emergency room complaining of fever, nausea, vomiting, and intense thirst. A urine test was positive for ketones, and her blood glucose levels were 400 mg/dL. Review Table 26-4, and consider the advantages and disadvantages that intensive therapy might have for Nora. Glycemic control during pregnancy offers the best chance of a safe delivery and a healthy infant.
Only a trace of fluoride occurs in the human body hair loss 5 month old buy 0.5 mg dutasteride with amex, but with this amount hair loss essential oil recipe 0.5mg dutasteride mastercard, the crystalline deposits in bones and teeth are larger and more perfectly formed hair loss cure news 2012 cheap dutasteride 0.5 mg visa. Fluoride Roles in the Body As Chapter 12 explained hair loss juice fast order dutasteride 0.5mg, during the mineralization of bones and teeth, calcium and phosphorus form crystals called hydroxyapatite. Drinking water is usually the best source of fluoride, and more than 65 percent of the U. In mild cases, the teeth develop small white specks; in severe cases, the enamel becomes pitted and permanently stained (as shown in Figure 13-11). Fluorosis occurs only during tooth development and cannot be reversed, making its prevention a high priority. To limit fluoride in- Key bone nutrients: · Vitamin D, vitamin K, vitamin A · Calcium, phosphorus, magnesium, fluoride For perspective, 1 part per million (1 ppm) is approximately 1 mg per liter. Fluoridation of public water supplies can significantly reduce the incidence of dental caries, but excess fluoride during tooth development can cause fluorosis-discolored and pitted tooth enamel. Chromium Roles in the Body Chromium helps maintain glucose homeostasis by enhancing the activity of the hormone insulin. When chromium is lacking, a diabetes-like condition may develop with elevated blood glucose and impaired glucose tolerance, insulin response, and glucagon response. In spite of these relationships, research findings suggest that chromium supplements do not effectively improve glucose or insulin responses in diabetes. Chromium Supplements Supplement advertisements have succeeded in convincing consumers that they can lose fat and build muscle by taking chromium picolinate. Whether chromium supplements (either picolinate or plain) reduce body fat or improve muscle strength remains controversial. Dietary deficiencies of molybdenum are unknown because the amounts needed are minuscule-as little as 0. Legumes, breads and other grain products, leafy green vegetables, milk, and liver are molybdenum-rich foods. Characteristics of molybdenum toxicity include kidney damage and reproductive abnormalities. Vanadium, too, is necessary for growth and bone development and for normal reproduction. Cobalt is a key mineral in the large vitamin B12 molecule (see Figure 13-12), but it is not an essential nutrient and no recommendation has been established. Boron may play a key role in brain activities; in animals, boron strengthens bones. Even arsenic-famous as a poison used by murderers and known to be a carcinogen-may turn out to be essential for human beings in tiny quantities. The alternative name for vitamin B12, cobalamin, reflects the presence of cobalt in its structure. Contaminant minerals include the heavy metals lead, mercury, and cadmium that enter the food supply by way of soil, water, and air pollution. This section focuses on lead poisoning because it is a serious environmental threat to young children and because reducing blood lead levels in children is a goal of Healthy People 2010. Like other minerals, lead is indestructible; the body cannot change its chemistry. Chemically similar to nutrient minerals like iron, calcium, and zinc (cations with two positive charges), lead displaces them from some of the metabolic sites they normally occupy but is then unable to perform their roles. Similarly, lead competes with calcium in the brain, but it cannot signal messages from nerve cells. Excess lead in the blood also deranges the structure of red blood cell membranes, making them leaky and fragile. Lead interacts with white blood cells, too, impairing their ability to fight infection, and it binds to antibodies, thwarting their effort to resist disease. In addition to its effects on the blood, lead impairs many body systems, most notably causing irreversible damage to the central nervous system.
