AUTOIMMUNE CNS Dec 2020 MNT Mega Quizlet
FATIGUE (other choices = exophthalmous, tachycardia, tremor of extremities)
***Hyperthyroid symptoms do NOT include:
___________is a glycoprotein secreted by parietal cells (in the fundic region of the stomach) of the gastric mucosa in the gastric juice that is necessary for the absorption of dietary vitamin B12
Intrinsic factor (IF)
o In autoimmune Hashimoto's thyroiditis, supplementing with____________ may exacerbate the condition.
Iodine Because iodine stimulates production of TPO, this in turn increases the levels of TPO Abs dramatically, indicating an autoimmune flare-up. o Some people develop symptoms of an overactive thyroid, whereas others have no symptoms despite tests showing an elevated level of TPO Abs. Therefore one must be cautious regarding the use of high-dose iodine; however, a clinical evaluation and/or assessment (such as UI excretion laboratories) may help reveal whether iodine supplementation is warranted
It has been suggested that drinking large amounts of tea may increase the risk of developing ______________whereas other studies suggest a protective role
RA
What 3 measurements are useful in the diagnosis of RA?
RF (Rheumatoid Factor), anti-nuclear antibodies (ANA), and antibodies to citrullinated protein antigens (ACPAs).
True or False In hemolytic anemia, there is decreased RBC production - result of disordered iron metabolism
True o Important to not confuse with iron deficiency anemia
True or False: Neurological problems such as MS, Parkinson's, and ALS are all considered to be autoimmune conditions.
True An autoimmune disease develops when your immune system, which defends your body against disease, decides your healthy cells are foreign. As a result, your immune system attacks healthy cells. Depending on the type, an autoimmune disease can affect one or many different types of body tissue. Most common types: rheumatoid arthritis, lupus, celiac disease, Sjogren's syndrome, multiple sclerosis, ankylosing spondylitis, type 1 diabetes, alopecia areata
which type of hemolytic anemia occurs when § Immune system attacks and destroys own RBCs when blood is exposed to 32-50OF
cold antibody hemolytic anemia · IgM antibodies that normally attack bacteria attach to RBCs and cause agglutination (binding in clumps) · RBCs are prematurely destroyed

Functional tests for scleroderma (digestive connection)
-SIBO breath test -vitamin D -Stool -food and environmental sensitivities -DHEA and cortisol -liver function -silicon antibodies -nutrient testing such as homocysteine -h pylori testing -EFA testing
Pathogenesis of IBD (Primer)
-Symptoms of IBD result from excessive inflammatory responses to a "trigger" that cause local autoimmune-like destruction of the intestinal mucosa. -During an inflammatory episode, intestinal villi are damaged, producing nutrient malabsorption and increased intestinal permeability with pathologic translocation. Intestinal permeability remains increased even in the absence of active inflammation. Increased intestinal permeability interacts additively with food sensitivities and nutrient intolerances to produce systemic comorbidities. In addition, IBD may be accompanied by a markedly increased sensitivity to commensal bacteria.; About 2/3 of all GALT lymphocytes are terminally-differentiated TH-1 T-helper lymphocytes that secrete interferon-γ (IFN-γ) when activated. IFN-γ activates local phagocytes and is chemoattractant for neutrophils. Active lesions of IBD are rich in IFN-γ, tumor necrosis factor-α (TNF-α) and the proinflammatory interleukins (IL), IL-1, IL-6, IL-8 and IL-12 that increase secretion of IFN-γ by TH-1 T-helper lymphocytes. In contrast, antiinflammatory IL-2, IL-4, IL-5 and IL-10 that inhibit the secretion of IFN-γ by TH-1 T- helper lymphocytes are absent Intramucosal bacterial antigens stimulate activation of nuclear transcription factor NF-κB in a subpopulation of GALT macrophages (suggesting that IBD also has elements of a primary "mutant macrophage" disease). Activation of NF-κB triggers overproduction of TNF-α, which then acts in an autocrine/paracrine manner to stimulate IL-12 secretion by both affected and unaffected macrophages. In turn, IL-12 stimulates TH-1 T-helper lymphocyte secretion of IFN-γ; IFN- γ stimulates macrophage secretion of IL-1, IL-6, IL-8 and TNF-α; and IL-1, IL-6, IL-8 and TNF-α stimulate macrophage secretion of IL-12 in a positive feedback loop while inhibitingTH-2 T-helper lymphocyte secretion of antiinflammatory IL-2, IL-4, IL-5 and IL-10. Interleukin imbalance, triggered and reinforced by aberrant macrophages, results in an imbalance of TH-1 and TH-2 T-helper lymphocytes and causes excessive secretion of pro- inflammatory reactive oxygen species, nitric oxide and prostaglandin PGE2 and inhibition of sIgA secretion. -Consequently, there is increased bacterial secretion of adhesion molecules and proteolytic enzymes which facilitate bacterial penetration of the mucosa. -
Pathophysiology of fibromyalgia
-There are no obvious signs of inflammation or degeneration in the tissues. -The cause is not known, but it appears to be related to altered central neurotransmission, resulting in increased soft tissue sensitivity to substance P, a neurotransmitter involved in pain sensation. -The incidence is higher in women 20 to 50 years of age. - There is often a history of prior trauma or osteoarthritis. -Aggravating factors include sleep deprivation, stress, and fatigue (Gould page 176) Digestive connection page 388 -Can be a physical manifestation of emotional trauma -often have low acetylcarnitine synthesis or viral infections as trigger Reference sheet for CNS group ● Histological/functional changes in muscle tissue ● Mitochondrial Defects: ● Increased oxidative stress ● Hypothalamic-pituitary-adrenal (HPA) alterations Increased Inflammatory/immune activation state: ● Alterations In Gut Flora -○ Several studies have demonstrated that 90- 100% of patients with FM had SIBO in a dose-response relationship ● though it occurs most often in women than men (ratio 7:1) and often starts in middle age > 50 y/o

1. If conscious, immediately give sweet fruit juice, honey, candy, or sugar. 2. If unconscious, give nothing by mouth (require intravenous glucose 50%). Gould CH 16 page 410
Explain the process of B12 absorption
1. The fundic region of the stomach release pepsin, which help release B12 from its binding proteins. Once detached, B12 attaches to a salivary protein called R protein or haptocorrin 2. The B12-haptocorrin protein complex passes through the stomach to be secreted by pancreatic proteases in the duodenum. 3. Once released, B12 attaches to a glycoprotein called IF that is secreted by parietal cells. 4. The B12-IF complex once in the distal ileum attaches to IF receptors in the intestinal enterocytes, where the complex is endocytosed by the ileul enterocytes, 5. B12 associates itself with a carrier protein TCII which carries B12 to other parts of the body 6. This is why IF is important B12 is important for B12 absorption. A lack of IF can cause malabsorption of B12.

In what autoimmune disease is the elimination diet is not appropriate because it is too restrictive and not relevant to their care. Intervention to prevent malnutrition, possibly keto, and monitor dysphagia
ALS
Which of the following is an important component in the nutritional assessment of patients with rheumatoid arthritis? a. ADLs b. Degree of malabsorption c. Blood glucose control d. Nitrogen balance
ANS: A Because rheumatoid arthritis (RA) can affect mobility, activities of daily living (ADLs) should be assessed. An inability to perform basic self-care skills can have a negative impact on the patient's ability to feed herself. Support in the form of caregivers or adaptive equipment may be needed to ensure nutritional adequacy. Malabsorption is not a consequence of RA. Blood glucose control depends on the presence of diabetes and other lifestyle factors. Nitrogen balance may be used to monitor protein status; however, simple monitoring of the patient's weight and anthropometric measures gives an idea about protein status without need for a nitrogen balance study. REF: p. 799 CH 39 Krause
Current research suggests that which of the following play a role in the inflammatory process? a. Polyunsaturated fatty acids b. Monounsaturated fatty acids c. Omega-3 and omega-6 fatty acids d. Medium-chain triglycerides
ANS: C Omega-6 fatty acids promote production of cytokines, which then go on to stimulate the inflammation process. Leukotriene B5 is also produced and contributes to inflammation by acting as a weak inflammation inducer and chemotactic agent. By substituting omega-6 fatty acids with omega-3 fatty acids, production of antiinflammatory mediator proteins, such as leukotriene B4, increases. Because MCTs are artificially produced, they have not been investigated in regard to a role in inflammation. REF: p. 804 CH 39 Krause
Polycystic ovary syndrome (PCOS) is characterized by which of the following biochemical and endocrine abnormalities? a. Elevated testosterone, insulin resistance, and impaired glucose tolerance b. Thyrotoxicosis, iodine deficiency, and elevated estrogen c. Impaired glucose tolerance, increased T4 conversion, and hypertension d. Low blood calcium, thyroid receptor hypersensitivity, and elevated cortisol
ANS: A Biochemical and endocrine abnormalities in women with PCOS include elevated levels of androgens (dehydroepiandrosterone, testosterone, and androstenedione), hyperinsulinemia (which results from insulin resistance), impaired glucose tolerance, and hyperlipidemia. Hyperandrogenism is responsible for many of the symptoms of PCOS, such as reproductive and menstrual abnormalities, hirsutism, and acne.
Which of the following contributes to the development of type 1 DM? a. Autoantibodies that contribute to the destruction of beta-cells b. Insulin resistance and beta-cell failure c. Increase in insulin-antagonist hormone levels d. Diet and sedentary lifestyle
ANS: A Immune-mediated diabetes mellitus (DM) is the form of type 1 DM that results from autoimmune destruction of the pancreatic beta-cells. This results in the patient's inability to produce insulin. Idiopathic type 1 DM is the other form, and it is DM that has no known etiology. Insulin resistance and beta-cell failure are what lead to the development of type 2 DM. Diet and sedentary lifestyle can contribute to this development. Gestational diabetes mellitus develops because of an increase in the release of insulin-antagonist hormones during pregnancy. These increased hormone levels contribute to an insulin resistance in the pregnant woman. Krause CH 30
Which of the following conditions is NOT a disease of autoimmune origin? a. OA b. RA c. SLE d. Scleroderma
ANS: A Osteoarthritis is not autoimmune in origin. Rheumatoid arthritis, systemic lupus erythematosus, and scleroderma are all conditions with autoimmune origins. REF: p. 797 CH 39 Krause
Before 1960, reports surfaced that soy formula-fed infants were developing hypothyroidism. The addition of what supplement to these formulas ameliorated this problem? a. Iodine b. Selenium c. Iron d. Tyrosine
ANS: A Soybean, an important source of protein in many developing countries, has goitrogenic properties when iodine intake is limited. The isoflavones, genistein and daidzein, inhibit the activity of TPO and can lower thyroid hormone synthesis. Furthermore, soybean interrupts the enterohepatic cycle of thyroid hormone metabolism. Since the addition of iodine to soy-based formulas in the 1960s, there have been no further reports of hypothyroidism developing in soy formula-fed infants. REF: p. 625
How do sulfonylureas and meglitinides help to lower blood glucose levels? a. Promoting beta-cell secretion of insulin b. Decreasing the insulin sensitivity of the receptor cell c. Increasing glucose formation from liver glycogen d. Decreasing deamination of protein
ANS: A Sulfonylureas and meglitinides are oral glucose-lowering medications that act as insulin secretagogues. Their action is to stimulate the pancreatic secretion of insulin. Biguanides and thiazolidinediones are insulin-sensitizing medications that lower insulin resistance and decrease hepatic glucose production from glycogenolysis and gluconeogenesis. REF: p. 599, Krause CH 30
What condition occurs when rebound hyperglycemia follows an episode of hypoglycemia? a. Somogyi effect b. Cushing syndrome c. Dawn phenomenon d. Hyperglycemic hyperosmolar state
ANS: A The Somogyi effect may be caused by excessive exogenous insulin administration. In response to the hypoglycemia that results, the counterregulatory hormones are secreted to promote gluconeogenesis. This results in an increase in blood glucose levels. Cushing syndrome is a rare condition involving the excessive secretion of cortisol. The dawn phenomenon involves an increase in morning blood glucose because of an increased need for insulin. The hyperglycemic hyperosmolar state is a complication in older adults with diabetes. In this condition, the patient has a very high blood glucose level but no ketones. REF: p. 613, Krause CH 30
How are thromboxanes involved in the inflammation process? a. Activation of platelet aggregation b. Activation of cytokines c. Attraction of neutrophils and macrophages d. Production of arachidonic acid
ANS: A The role of thromboxanes in the inflammatory process is to promote platelet aggregation in the area of inflammation and to release growth factors and proteases. Cytokines are proteins that promote the production of prostaglandins, a group of mediators involved in a variety of physiologic processes. Leukotrienes promote the attraction of neutrophils, macrophages, and fibroblasts into the area of inflammation. Arachidonic acid is a fatty acid precursor of various prostaglandins. REF: p. 792 CH 39 Krause
More than 90% of people with autoimmune thyroid disease have a genetic defect affecting their ability to metabolize what? a. Vitamin D b. Flavonoids c. Selenium d. Tyrosine
ANS: A Vitamin D is considered a prohormone with antiproliferative, differentiating, and immunosuppressive activities. Vitamin D also appears to work with other nutritional factors to help regulate immune sensitivity and may protect against development of autoantibodies. REF: p. 628
Which of the following areas lacks blood vessels and nerves? a. Epidermis b. Dermis c. Subcutaneous tissue d. Fatty tissue
ANS: A REF: 142 Gould CH 8
Thyroid health has been shown to be impacted by the elimination of which foods? a. Seafood b. Gluten c. Mushrooms d. Barley
ANS: B A variety of food antigens could induce antibodies that cross-react with the thyroid gland. Eliminating gluten-containing grains has been suggested for treatment of hypothyroidism of unknown origin. Selenium has been shown to enhance thyroid function; mushrooms, barley, and seafood are good sources of selenium. REF: p. 622
Some plant foods (cauliflower, broccoli, cabbage) exert antithyroid activity through what mechanism? a. Binding iodine species b. Inhibiting thyroid peroxidase c. Increasing thyroglobulin antibodies d. Stimulating cortisol
ANS: B Cyanogenic plant foods (cauliflower, broccoli, cabbage, Brussels sprouts, mustard seed, turnip, radish, bamboo shoot, and cassava) exert antithyroid activity through inhibition of TPO. The hydrolysis of some glucosinolates found in cruciferous vegetables (e.g., progoitrin) may yield goitrin, a compound known to interfere with thyroid hormone synthesis. REF: p. 625
Which of these is NOT a product of the thyroid? a. Thyroxine (T4) b. Calcitonin c. Reverse T3 (rT3) d. Triiodothyronine (T3)
ANS: C Reverse T3 (rT3) is derived from T4 through the action of deiodinase. It is an isomer of T3 but is not itself produced by the thyroid. REF: p. 619
What should the person with type 1 DM do when planning to exercise? a. Strictly adhere to dietary restrictions. b. Decrease insulin dosage dependence on duration and intensity of exercise. c. Plan to exercise when the insulin is peaking. d. Take an extra injection of insulin.
ANS: B Decreasing the amount of insulin injected is necessary to prevent hypoglycemia that can occur during exercise. Prolonged or intensive exercise may require a modest decrease of 1 to 2 U of rapid- and short-acting insulin before and possibly after exercise. As an alternative, the person with type 1 DM may ingest carbohydrate before or after exercise to prevent hypoglycemia. Exercising at the time of insulin peak action and providing extra insulin can increase the likelihood of hypoglycemia. REF: p. 598, Krause CH 30
What drug(s) is(are) the first line of therapy for controlling the inflammatory process seen in arthritis? a. Corticosteroids b. Salicylates c. Gold salts d. Methotrexate
ANS: B For the control of pain and inflammation in rheumatoid arthritis, salicylates and nonsteroidal antiinflammatory drugs are first used. Methotrexate is a secondary medication used, but it is a folate antagonist and could contribute to neutropenia with long-term use. Corticosteroids have other metabolic derangement effects when used continuously. Use of gold salts can promote proteinuria. REF: p. 802 CH 39 Krause
Iodine deficiency is often a culprit in thyroid disorders. However, in which of these thyroid conditions may supplementing with iodine exacerbate the condition? a. Adrenal fatigue b. Hashimoto thyroiditis c. Polycystic ovary syndrome (PCOS) d. Graves disease
ANS: B In autoimmune Hashimoto thyroiditis, supplementing with iodine may exacerbate the condition. Because iodine stimulates production of TPO, this in turn increases the levels of TPO antibodies (TPO Abs) dramatically, indicating an autoimmune flare-up. Some people develop symptoms of an overactive thyroid, but others have no symptoms despite tests showing an elevated level of TPO Abs. Therefore, one must be cautious regarding the use of iodine. Furthermore, although iodine deficiency is the most common cause of hypothyroidism for most of the world's population, in the United States and other westernized countries, Hashimoto thyroiditis accounts for the majority of cases. REF: p. 622 Krause CH 31
Thyroid health in some adults can be improved by increasing the conversion of T4 to T3. This can be accomplished by a. supplementing with tyrosine. b. correcting zinc deficiencies with zinc glycinate or zinc citrate. c. increasing naturally occurring flavonoids in the diet. d. cautiously supplementing with lipoic acid.
ANS: B Nutritional agents that help support proper deiodination by the type 1 5'-deiodinase enzyme include selenomethionine (as L-selenomethionine) and zinc (as zinc glycinate or zinc citrate). Human studies have repeatedly demonstrated consequent reduced concentrations of thyroid hormones when a zinc deficiency is present. Supplementation with tyrosine does not appear to have a beneficial effect on elevating thyroid hormones. Synthetic flavonoid derivatives can decrease serum T4 concentrations and inhibit both the conversion of T4 to T3 and the metabolic clearance of rT3 by the selenium-dependent 5'-deiodinase. Naturally occurring flavonoids appear to have a similar inhibitory effect. Lipoic acid reduces the conversion of T4 to T3. REF: p. 628
What must a patient demonstrate to be a candidate for use of oral glucose-lowering medications? a. Functioning alpha-cells in the pancreas b. Functioning beta-cells in the pancreas c. Functioning gastrointestinal mucosa d. Resistance to insulin at all times
ANS: B Oral glucose-lowering medications may be used in the treatment of patients with type 2 DM; therefore, the patient has to have beta-cell function for the production of insulin. The mechanisms of action for the oral glucose-lowering medications include the stimulation of pancreatic insulin secretion. Other mechanisms of action include reducing insulin resistance at muscle and adipose tissue and decreasing hepatic glucose output. REF: p. 599, Krause CH 30
Which of the following conditions is characterized by hardening of the skin and visceral organs? a. Gout b. Scleroderma c. Fibromyalgia d. Sjögren syndrome
ANS: B Scleroderma is a chronic, systemic sclerosis or hardening of the skin and visceral organs characterized by deposition of fibrous connective tissue. REF: p. 808 CH 39 Krause
Which of the following may have a beneficial effect in the treatment of patients with Sjögren syndrome? a. Increase frequency of meals. b. Moisten foods with sauces or gravies. c. Limit fiber. d. Increase citrus fruits.
ANS: B Sjögren syndrome is a chronic autoimmune inflammatory disease that affects the exocrine glands, particularly the salivary and the lacrimal glands, leading to dryness of the mouth (xerostomia) and of the eyes (xerophthalmia). Modification of dietary habits to cope with oral symptoms, particularly to improve biting (cutting fruits, vegetables, and meats in small pieces), chewing (making foods softer by preparing them as soups, broths, casseroles, or as tender cooked vegetables and meats), and swallowing (moistening foods with sauces, gravies, yogurts, or salad dressings) often helps. Foods that worsen oral symptoms should be limited, like citrus fruits, as well as irritant, hot, or spicy foods. REF: p. 805 CH 39 Krause
Which of the following is an autoimmune disorder that presents with severe fatigue, painful or swollen joints, and skin rashes? a. Chronic fatigue syndrome b. Systemic lupus erythematosus c. Raynaud syndrome d. Scleroderma
ANS: B Systemic lupus erythematosus (SLE) involves inflammation, resulting in extreme fatigue, arthritis, unexplained fever, skin rashes, and kidney problems. SLE has a genetic predisposition for the overproduction of type 1 interferon and other cytotoxic cells that can affect all organ systems. Chronic fatigue syndrome is characterized by extreme fatigue that does not improve with rest. Raynaud syndrome is an ischemia or coldness in the fingers that makes it difficult to perform fine motor functions. Raynaud syndrome may be one of the symptoms that happen in scleroderma, which is a progressive disorder that involves the deposition of fibrous connective tissue in the skin and visceral organs. REF: p. 808 CH 39 Krause
Although some T3 is produced in the thyroid, approximately 80% to 85% is generated outside the thyroid in which organs? a. Nervous system and adrenal glands b. Liver and kidneys c. Pancreas and gastrointestinal tract d. Hypothalamus and pituitary gland
ANS: B T3 is primarily produced by conversion of T4 in the liver and kidneys. The pituitary and nervous system are capable of converting T4 to T3, so they are not reliant on T3 produced in the liver or kidney. REF: p. 620
__________ is NOT a symptom of type 1 DM. a. Hyperglycemia b. Loss of thirst sensation c. Weight loss d. Polydipsia
ANS: B The common symptoms of type 1 diabetes mellitus include hyperglycemia, polyuria, polydipsia, weight loss, dehydration, electrolyte disturbance, and ketoacidosis. Type 1 DM tends to increase the thirst sensation as opposed to blocking it. REF: p. 588, Krause CH 30
Which of the following statements about glycemic index (GI) is TRUE? a. Consuming low-GI meals (<70) improves overall glycemic control. b. Specific carbohydrate foods can have a variable GI. c. When compared with an equal amount of starch, sucrose promotes a greater glycemic response. d. The GI of glucose is lower than the GI of white bread.
ANS: B The difficulty of working with the GI concept is that the GI of an individual food may vary. This is part of the reason that the ADA has not fully adopted GI and glycemic load as approaches to meal planning. Low-GI foods are those with a GI of less than 55. Selection of low-GI foods may help in fine-tuning postprandial glycemic response, but research presents inconsistent results in relation to overall glycemic control. Equal amounts of starch and sucrose result in identical glycemic responses. The GI of glucose is 100. The GI of white bread is 70. REF: pp. 595-596, CH 30
Which of the following is one of the ADA's MNT goals for all people with diabetes? a. Promote weight loss. b. Achieve blood glucose control. c. Limit dietary cholesterol. d. Limit intake of simple carbohydrates.
ANS: B Achieve blood glucose control. The first MNT goal for all people with diabetes is to achieve and maintain normal blood glucose levels and lipid and lipoprotein profiles and blood pressure levels that reduce the risk for vascular disease. The other MNT goals include preventing or slowing the progression of chronic complications of diabetes mellitus, addressing the individual's nutritional needs, and limiting food choices only based on evidence while maintaining the pleasure of eating. Diabetes may affect children and pregnant women, and weight loss is not important to maintaining health in these population groups. Diabetes is associated with CVD risk and MNT but dietary cholesterol is no longer restricted for CVD prevention. Research evidence does not substantiate a recommendation to limit simple carbohydrate intake in the treatment of diabetes. REF: p. 605, CH 30 Krause
Botanical preparations have been found in animal studies to influence thyroid activity. Commiphora mukul (guggulsterones from guggul extract) has strong thyroid stimulatory action, demonstrated by a. increasing cortisol production. b. decreasing iodine uptake by the thyroid. c. increasing TPO activity. d. decreasing serum T4 concentrations.
ANS: C Administration of 1 mg of Commiphora mukul/100 g body weight increases iodine uptake by the thyroid, increases TPO activity, and decreases lipid peroxidation, suggesting that increased peripheral generation of T3 might be mediated by this plant's antioxidant effects. REF: p. 628
Which of the following is NOT true about amylin? a. It is a glucoregulatory hormone. b. It is produced in pancreatic beta-cells. c. It counteracts the effects of insulin. d. Deficiency is associated with TIDM.
ANS: C Amylin, a glucoregulatory hormone, is also produced in the beta-cells of the pancreas and is cosecreted with insulin. It works in concert with insulin to regulate postprandial serum glucose levels and suppresses glucagon secretion. REF: p. 587
Which of the following CAM therapies has been demonstrated as effective in the treatment of rheumatoid arthritis? a. Copper bracelets b. Echinacea c. Borage and evening primrose oil d. Thunder god vine
ANS: C Gamma-linolenic acid is an omega-6 fatty acid found in the oils of borage and primrose oil that can be converted to the antiinflammatory PGE-1. Copper bracelets have been suggested to allow for absorption of copper through the skin, but no studies have substantiated this. Echinacea therapy is among a number of CAM therapies that the Arthritis Foundation recommends that people with rheumatoid arthritis should not use. Thunder god vine has been used in China to treat patients with a number of autoimmune disorders, but no consistent, high-quality vine preparations are available in the United States. REF: p. 791 CH 39 Krause
Which spices are included in the "antiinflammatory diet"? a. Thyme, cayenne, and cloves b. Oregano, lemon peel, and thyme c. Ginger, curry, turmeric, and rosemary d. Cayenne, cumin, and parsley
ANS: C Ginger, curry, and turmeric are specifically included in the antiinflammatory diet because of their antiinflammatory effects CH 39 Krause .
Low energy, cold hands and feet, fatigue, hypercholesterolemia, muscle pain, depression, and a positive test result for thyroid peroxidase antibodies could all be indicative of what condition? a. Diabetes mellitus b. Graves disease c. Hashimoto thyroiditis d. Polycystic ovary syndrome (PCOS)
ANS: C Hashimoto thyroiditis is an autoimmune disorder in which the immune system attacks and destroys the thyroid gland. It is the most common form of hypothyroidism. The TPO Abs test is the most important because TPO is the enzyme responsible for the production of thyroid hormones and the most frequent target of attack in Hashimoto thyroiditis. REF: p. 622
Graves disease is an autoimmune disease in which the thyroid is diffusely enlarged (goiter) and overactive, producing an excessive amount of thyroid hormones. It is the most common cause of hyperthyroidism (overactive thyroid) in the United States. What is the primary target of circulating autoantibodies in this disease? a. Insulin receptors b. Thyroid-stimulating hormone (TSH) receptors c. Thyrotropin-releasing hormone (TRH) receptors d. Cortisol receptors
ANS: C In Graves disease, the TRH receptor itself is the primary autoantigen and is responsible for the manifestation of hyperthyroidism. The thyroid gland is under continuous stimulation by circulating autoantibodies against the TRH receptor, and pituitary TSH secretion is suppressed because of the increased production of thyroid hormones. These thyroid-stimulating antibodies cause release of thyroid hormone and Tg and stimulate iodine uptake, protein synthesis, and thyroid gland growth. REF: p. 627
What does insulin promote in regard to the metabolism of lipids? a. Lipolysis in the liver b. An increase in serum free fatty acids c. Lipogenesis in the liver d. The breakdown of fat stores in adipose tissue
ANS: C In regard to lipids, insulin stimulates the conversion of pyruvate to fatty acids in the liver as part of the process of lipogenesis. Insulin's anticatabolic activities in relation to lipids include the inhibition of lipolysis and the prevention of excessive ketone production. Insulin's transport activity includes the activation of lipoprotein lipase to facilitate the transport of triglycerides into adipose tissue. REF: p. 593, Krause CH 30
What is the recommendation for self-monitoring of blood glucose? a. Every morning and every night before bed b. When there is a change in activity level or diet c. Four or more times daily for type 1 DM and one to four times for type 2 DM d. At least eight times a day for type 1 DM
ANS: C Patients with type 1 DM should perform SMBG four times or more daily, including before each meal and at bedtime. Patients with type 2 DM should perform SMBG one to four times daily to help in achieving glucose goals. Whenever they add to or modify their therapies, patients with either DM should test more often. REF: p. 603, Krause CH 30
Which of the following is characteristic of Sjögren syndrome? a. Excessive sweating and salivation b. Temporomandibular joint symptoms c. Diminished production of tears and saliva d. Diminished production of hydrochloric acid
ANS: C Sjögren syndrome is an autoimmune disorder that affects tear and salivary glands. These tissues are attacked by the immune system, and destruction of the glands leads to decreased production of tears and saliva. Temporomandibular joint symptoms occur in the jaw. REF: p. 805 CH 39 Krause
Which of these is NOT required for the production of thyroxine (T4) and triiodothyronine (T3)? a. Thyroid peroxidase (TPO) b. Tyrosine c. Thyroid-binding globulin (TBG) d. Iodide
ANS: C The synthesis of T3 and T4 requires tyrosine, a key amino acid involved in the production of thyroid hormone, and the trace mineral iodine. Two additional molecules of iodine bind to the tyrosyl ring in a reaction that involves thyroid peroxidase (TPO), an enzyme. When T4 is released from the thyroid, it is primarily in a bound form with thyroid-binding globulin (TBG), a protein that transports thyroid hormones through the bloodstream but is not required for production. REF: p. 620
A group of self-reacting antibodies found in the sera of rheumatic patients a. include CRP. b. are known to suppress the immune system. c. are known as rheumatoid factor. d. are known as eicosanoids.
ANS: C The term rheumatic factor is used to refer to a group of self-reacting antibodies found in the sera of rheumatic patients. It is used to screen for and monitor rheumatic disease along with CRP. Eicosanoids are modulators of the inflammation process that include prostaglandins. REF: p. 792 CH 39 Krause
What is a raised, thin-walled lesion containing clear fluid called? a. Papule b. Pustule c. Vesicle d. Macule
ANS: C REF: 143 Gould CH 8
Dietary intervention is a key therapeutic tool in managing patients with thyroid disease. In the absence of nutritional deficiencies, what is the main goal of nutritional support? a. Maintaining vitamin sufficiency b. Decreasing oxidative stress c. Increasing iodine concentrations d. Reducing antithyroidal antibodies
ANS: D A variety of food antigens could induce antibodies that cross-react with the thyroid gland. A food elimination diet using gluten-free grains and possible elimination of casein, the predominant milk protein, might be considered for patients with hypothyroidism of unexplained origin. REF: p. 628
Maintaining thyroid hormone function throughout the aging process appears to be an important hallmark of healthy aging. What characteristic is an indicator of thyroid health in centenarians? a. Decreased free T4 and rT3 levels b. An increased libido c. Constant cortisol production d. The absence of circulating thyroid autoantibodies
ANS: D Because unhealthy aging is associated with a progressively increasing prevalence of organ-specific and nonorgan-specific autoantibodies, the absence of these antibodies may represent a significantly reduced risk for cardiovascular disease and other chronic age-related disorders. REF: p. 624
Which of the following is NOT a potential acute complication of type 1 DM? a. Hypoglycemia b. Hyperglycemia c. Ketoacidosis d. Blood vessel damage
ANS: D Blood vessel damage may be either microvascular or macrovascular in nature; however, this occurs because of long-term exposure of the blood vessels to the physiologic changes that commonly occur with diabetes, such as hyperglycemia, hyperlipidemia, and hypertension. Hypoglycemia, hyperglycemia, and ketoacidosis are acute complications of diabetes mellitus because each of these can occur rapidly in relation to alterations in the patient's lifestyle, health, or use of medications. REF: p. 613, Krause Ch 30
Selenium deficiency, inadequate protein, excess carbohydrates, chronic illness, and stress (high cortisol levels) can all impact what thyroid metabolic process? a. Thyroid-stimulating hormone (TSH) production b. Organification of iodide c. Thyroid-binding globulin (TBG) T4 transport d. 5'-Deiodinase conversion of T4 to T3
ANS: D Changes in 5'-deiodination occur in a number of situations, such as stress, poor nutrition, illness, selenium deficiency, and drug therapy. Toxic metals such as cadmium, mercury, and lead have been associated with impaired hepatic 5'-deiodination in animal models. Free radicals are also involved in inhibition of 5'-deiodinase activity. REF: p. 622
Which of the following is NOT a microvascular disease associated with hyperglycemic patients? a. Retinopathy b. Neuropathy c. Nephropathy d. Peripheral vascular disease
ANS: D Microvascular diseases are ones that affect smaller blood vessels and nerves. Retinopathy, neuropathy, and nephropathy have been the three primary microvascular diseases that develop from uncontrolled diabetes mellitus. Peripheral vascular disease is classified as a macrovascular disease because it involves larger blood vessels. Krause CH 30
Which of the following would NOT result in postprandial (reactive) hypoglycemia? a. Rapid glucose absorption b. Excessive insulin secretion c. Insufficient glucagon secretion d. Excessive hepatic gluconeogenesis
ANS: D Postprandial or reactive hypoglycemia occurs within 2 to 5 hours after eating. During this period of time, the body absorbs glucose and responds to increased blood glucose levels by secreting insulin. However, during this same time, as glucose is being provided by the diet, the liver is not stimulated to produce additional glucose through gluconeogenesis. A defect in glucagon response could contribute to the hypoglycemia by not triggering gluconeogenesis. REF: p. 615, Krause CH 30
What is the role of prostacyclin or PGI2? a. Converts arachidonic acid into PGE1 b. Converts arachidonic acid into PGE2 c. Promotes platelet aggregation d. Inhibits platelet aggregation
ANS: D Prostacyclin relaxes smooth muscle and inhibits platelet aggregation and therefore has an antiinflammatory effect. Prostacyclin, similar to thromboxane (PGE1) and leukotriene (PGE2), is produced from arachidonic acid precursor. REF: p. 792 CH 39 Krause
Which insulin peaks in activity 2 to 3 hours after injection? a. Lispro (Humalog) b. Detemir (Levemir) c. NPH d. Regular
ANS: D Regular insulin is short-acting insulin that peaks within 2 to 3 hours of injection. Lispro is rapid-acting insulin that peaks within 1 to 2 hours. NPH is intermediate-acting insulin that peaks between 4 and 10 hours after injection. Detemir is long-acting insulin that stays in the blood system from 18 to 24 hours without a "peak" time of activity. Patients receiving detemir should be monitored 10 to 12 hours after injection for effects of the insulin. REF: p. 601, Krause CH 30
Which feature associated with the joint of a person affected with gout is different from the joint of a person affected with rheumatoid arthritis? a. Bone erosion b. Inflamed synovium c. Bone spurs d. Presence of tophi
ANS: D Tophi are deposits of uric acid that crystallize on the bone and cartilage, leading to damage of the joint. In rheumatoid arthritis, inflammation of the synovial fluid damages the cartilage and bone, leading to bone erosion and loss. Osteoarthritis is characterized by the presence of bone spurs in the joint. REF: p. 806 CH 39 Krause

A 16-year old teenage girl with Type I diabetes seeks counseling for erratic blood glucose levels. She is on the school track team and works out in the afternoons for 1 ½ hours. Her meal plan consists of 3 meals, a pre-exercise snack of one fruit, and a bedtime snack of ½ cup cereal and 1 cup of milk. Her insulin regimen is 3 units of regular insulin before breakfast and 2 units of regular insulin before dinner, and equal amounts of NPH mid-morning and at bedtime. Lately her pre-dinner blood glucose levels have been low. What would be the most effective nutrition intervention for her? A. Reduce the mid-morning NPH insulin by one unit and add a protein exchange to the afternoon snack. B. Increase the bedtime insulin and add another bread exchange to the bedtime snack. C. Reduce the afternoon exercise to 45 minutes and have her carry fruit juice with her in case she feels dizzy or weak. D. A & B
Answer: A - The most effective intervention would be to reduce the mid-morning NPH insulin by one unit and add protein exchange to the afternoon snack. NPH is an intermediate-acting insulin which has its peak effect in the afternoon. Reducing the amount of NPH by one unit and adding protein to the pre-exercise snack will help eliminate low blood glucose levels before the evening meal.

Answer: B. It is a condition of demylenization of the nerve sheath
Which of the following amino acid-derived neurotransmitters is linked to the etiology of ALS (Lou Gehrig's disease)? A. Tyrosine B. Arginine C. Tryptophan D. Glutamate
Answer: D. Glutamate; Glutamate is a neurotransmitter that sends signals in the brain and throughout the nerves in the body. Glutamate plays an important role during brain development. Normal levels of glutamate also help with learning and memory. Having too much glutamate in the brain has been associated with neurological diseases such as Parkinson's disease, multiple sclerosis, Alzheimer's disease, stroke, and ALS (amyotrophic lateral sclerosis or Lou Gehrig's disease). Problems in making or using glutamate have also been linked to a number of mental health disorders, including autism, schizophrenia, depression, and obsessive-compulsive disorder (OCD). Research in the early 1990s determined that ALS patients have raised levels of glutamate in the fluid bathing the brain and spinal cord. In fact, 40 percent of sporadic cases of ALS are characterized by this elevated glutamate in cerebrospinal fluid (CSF). Abundant evidence points to glutamate as a destructive factor in ALS. The first and so far only approved specific treatment for ALS is riluzole, a drug that modulates glutamate.

Schmidt's syndrome
Within the liver and kidney, the enzyme responsible for production of T3 is a _____________-dependent enzyme called 5-deiodinase, an enzyme that removes one molecule of iodine from T4 to form either T3 or rT3
Selenium
______________, as selenocysteine, is a cofactor for 5-deiodinase
Selenium If selenium is deficient, the deiodinase activity is impaired, resulting in a decreased ability to deiodinate T4 to T3. In animals, deficiencies of selenium are associated with impaired 5-deiodinase activity in the liver and kidney, as well as reduced T3 levels o Evidence suggests a strong linear association between lower T3 /T4 ratios and reduced selenium status, even among individuals considered to be euthyroid based on standard laboratory parameters o This association is particularly strong in older adults, possibly as the result of impaired peripheral conversion
Deiodinase inhibitors include
Selenium deficiency Inadequate protein too much carbohydrate high insulin chronic stress(cortisol) Cd, Hg, Pb and other heavy metal toxins Compromised liver/kidney function

_____________ is considered to be the most metabolically active thyroid hormone.
T3 Although some T3 is produced in the thyroid, approximately 80% to 85% is generated outside the thyroid gland, primarily by conversion via a deiodinase enzyme from T4 to T3 in the liver and kidneys. The pituitary and nervous system are also capable of converting T4 to T3 , and so are not reliant on T3 produced in the liver or kidney. Within the liver and kidney, the enzyme responsible for production of T3 is a selenium-dependent enzyme called 5-deiodinase, an enzyme that removes one molecule of iodine from T4 to form either T3 or rT3 · Some is produced in the thyroid, but approx. 80-85% is generated in liver and kidneys. Pituitary and nervous systems are also capable of converting T4 to T3

Which of the following is an important component in the nutritional assessment of patients with rheumatoid arthritis? a. ADLs b. Degree of malabsorption c. Blood glucose control d. Nitrogen balance
a-ADL's Because rheumatoid arthritis (RA) can affect mobility, activities of daily living (ADLs) should be assessed. An inability to perform basic self-care skills can have a negative impact on the patient's ability to feed herself. Support in the form of caregivers or adaptive equipment may be needed to ensure nutritional adequacy. Malabsorption is not a consequence of RA. Blood glucose control depends on the presence of diabetes and other lifestyle factors. Nitrogen balance may be used to monitor protein status; however, simple monitoring of the patient's weight and anthropometric measures gives an idea about protein status without need for a nitrogen balance study.
