Diabetes- Intro
-Condition of high blood sugar levels -Either a problem with the organ that produces insulin (pancreas) or a problem at the level of the cells to accept glucose, both cases result in elevated blood sugar levels Terms: Postprandial hypoglycemia: blood glucose levels that fall below normal within 2-5 hours after a meal Reactive hypoglycemia: normal insulin secretion, but increased insulin sensitivity and a reduced response to glucagon Insulin: hormone secreted by the pancreas, moves glucose from the bloodstream to the inside of the cell Ketones: substances produced by the liver when more fat is being used for energy instead of glucose as a result of an inadequate amount of insulin Diabetic ketoacidosis: serious complication of diabetes that occurs when the body produces very high levels of ketones Somogyi effects: hypoglycemia followed by rebound hyperglycemia. This may occur when a patient takes insulin before bed. If the insulin lowers the blood sugar too much, it can trigger a release of hormones that release glucose to the blood. These hormones can cause insulin resistance for several hours. Dawn phenomenon: an abnormal early morning increase in blood sugar levels, usually between 2-8am Honeymoon phase: the phenomenon some patients might experience shortly after being diagnosed with diabetes. May experience normal BS levels without needing insulin. Hyperosmolar hyperglycemic state: metabolic complication of type 2 diabetes characterized by severe hyperglycemia, dehydration, hyperosmolar plasma, altered consciousness, and absence of significant ketosis. Usually develops after a period of symptomatic hyperglycemia when fluid intake is inadequate Insulin shock: state where there is too much insulin in the bloodstream and blood sugar levels fall very low. Body becomes "starved" for glucose and begins to shut down 3 P's of diabetes: -Polyuria: condition of frequent urination. Develops bc kidneys are attempting to get rid of excess glucose in the blood -Polydipsia: condition of excessive thirst bc kidneys are excreting extra fluid from the blood -Polyphagia: condition of excess hunger. May be d/t glucose in the blood not being utilized for energy bc of the lack of insulin Diabetic nephropathy: kidney damaged caused by diabetes Diabetic neuropathy: nerve damaged caused by diabetes Glycemic index (GI): -used to rank carbs by their ability to raise blood glucose levels -white bread or glucose are used as the reference foods -GI does not measure how rapidly blood glucose levels rise. However, foods with a high GI tend to result in a quick rise, followed by a quick drop -Low GI foods produce a moderate rise/fall -Presence of fat & fiber lower the GI of food -GI and blood sugar response is only valid when a single food is consumed Glycemic Load (GL): -The glycemic index of a food divided by 100 and multiplied by its amount of available carbohydrate content (CHO - fiber) in grams -The GL can help determine how high blood sugar levels can rise since it includes the available CHO content -For example, watermelon has a high GI of 72, but a serving of watermelon contains so few carbohydrates that it has a GL of about 4 15/15 Rule: -easy way for a person to treat a hypoglycemic event -when blood sugar levels are below 70 mg/dL, consume 15 g of easily-digestible CHO -after consuming, blood sugar levels check again 15 minutes later -if levels are still below 70 mg/d, the cycle repeats -Infants only need 6 grams, toddlers need 8 grams, and small children need 10 grams -Insulin is counterproductive and should not be used in times of hypoglycemic reaction -If the person is unconscious, they should receive a shot of glucagon Classifications: Pre-diabetes: -Blood sugar high enough to be concerning, but not enough to be T2D -More than 1/3 Americans have pre-diabetes -Increases the risk for heart disease, stroke, and T2D -Risk factors for pre-diabetes: overweight, 45+ years old, family hx, physically active <3x/week, hx of gestational diabetes or birthing a baby over 9 lbs, PCOS Type 1 diabetes (IDDM): -Body either does not produce insulin or makes very little of it as a result of damage to the beta cells of the pancreas -More commonly first diagnosed in children, teens, and young adults -Insulin-dependent diabetes mellitus -Accounts for 5-10% of all diabetes cases -No known way to prevent onset Type 2 diabetes (NIDDM): -Cells do not respond normally to insulin (insulin resistance) -Causes the pancreas to over produce insulin and results in high blood sugar levels -Non-insulin dependent diabetes mellitus -90-95% of all diabetes cases -If uncontrolled, can lead to heart disease, kidney damage, and loss of vision Gestational Diabetes: -body cannot make enough insulin during pregnancy, resulting in higher-than-normal blood sugar levels -affects 2-10% of pregnancies every year in US -Increases the risk for high blood pressure during pregnancy and having a large baby that has to be delivered via C-section -Puts a baby at a higher risk of: >9 pounds at birth, born prematurely, low blood sugar, developing T2D later in life -Nearly half of women with gestational diabetes develop T2D after pregnancy

The dialysis machine performs the function of the kidneys Types of Dialysis: Hemodialysis: -administered typically 3 days/week at a dialysis center over a 3-5 hour session -access may be through an arteriovenous fistula, an artificial loop graft, or a subclavian catheter -waste products and electrolytes move by diffusion, ultrafiltration, and osmosis from the blood into the dialysate and are removed -patients are generally prescribed a renal diet with various restrictions. This is based on how effectively the dialysis is normalizing blood levels Peritoneal dialysis: -administered via a catheter placed in the peritoneum (abdominal lining) -administered in several exchanges throughout the day and is a more continuous process -dietary restrictions are often not as restrictive Renal Solute Load: -amount of nitrogenous waste and minerals that must be excreted by the kidney -protein is a major contributor -also takes sodium, potassium, and chloride into account -in healthy individuals, increasing fluid consumptions can lower the renal solute load. However, renal disease patients may have fluid restrictions, so they need to balance the renal solute load and fluid intake closely -Renal solute load = (g pro X 5.8) + (mEq sodium + mEq potassium + mEq chloride) -*this formulas is intended for adults, if calculating for children, 5.8 becomes 4.0 Symptoms: -Decreased appetite -fatigue -reduced mental acuity -CKD may not become apparent until kidney function is significantly impaired -decreased urine output -seizures -restless leg syndrome -hypertension -fluid retention and edema -heart failure Pathophysiology: - 5 main stages of renal disease -The decline of kidney function occurs as a result of one or several of the following factors: -Ischemia: decreased renal blood flow -Hypoxia: decreased oxygen flow in kidneys -Drugs or medications that can be toxic to the kidneys -hyperglycemia -genetic factors -autoimmune disease -In advanced renal failure, urine output is decreased and electrolytes and waste products can rise to toxic levels Diagnosis: -Blood tests: -levels of specific waste products to determine how well kidneys are filtering out waste -GFR, BUN, and creatinine levels -Urine tests: -creatinine clearance test: compares the creatinine in a 24 hour sample of urine to the creatinine level in the blood to show how much waste products the kidneys are filtering out -urine protein test: an excess amount of protein in the urine is called proteinuria, and this is an indicator of renal dysfunction -Imaging tests: -renal ultrasound: identifies abnormalities in the size or position of the kidneys or for obstructions, such as stones or tumors -CT scan: identify structural abnormalities or obstructions -Renal biopsy: -determines cause of renal failure Pertinent Labs: Glomerular filtration rate (GFR): -The rate at which the kidneys filter the blood -GFR # = filtering at that capacity -Lower GFR = more advanced stage -Normal: 90-120 ml/min -Mild kidney damage: 60-89 ml/min -Moderate kidney damage: 30-59 ml/min -Severe kidney damage: 15-29 ml/min -Kidney failure: < 15 ml/min Blood urea nitrogen (BUN): -Urea nitrogen comes from the breakdown of protein consumed in food -In renal failure, this is often elevated as the kidneys are unable to adequately clear urea nitrogen out of the blood -Normal range: 6-20 mg/dL -Renal disease: >20 mg/dL Creatinine: -creatinine is a waste product that is present in the blood from normal wear and tear of the muscle -as renal function declines, creatinine levels further increase above normal levels -normal range (men): 0.9-1.3 mg/dL -normal range (women): 0.6-1.1 mg/dL -renal disease: >1.2 mg/dL Electrolytes: -potassium: builds up in the blood as the kidneys are unable to adequately filter and excrete in the urine. Renal disease >5.0 mEq/L -phosphorus: builds up in the blood often in later stages of kidney disease as parathyroid hormone levels increase. RD >4.5 mg/dL -calcium: decreases as parathyroid hormone increases. phosphorus levels consequently increase in the blood. Calcium binds to phosphorus, thereby reducing calcium. RD <8.4 mg/dL Common medications: -Phosphate binders: -used when phosphorus levels are too high and not enough is removed during dialysis -when using phosphate binders, additional calcium and vitamin D supplements should be avoided to prevent hypercalcemia -commonly used: calcium carbonate (tums), calcium acetate, calcium chloride MNT: Sodium: -excess sodium can increase BP, fluid retention, and put strain on the kidneys and cardiovascular system -sodium restrictions vary from 2000-4000 mg/d Potassium: -mineral that controls nerve and muscle function to maintain proper fluid and electrolyte balance in the body -restriction ranges from 1500-4000 mg/d -leaching is a practice to lower potassium in some foods, such as potatoes Phosphorus: -involved in the acid-base balance in the body and regulates calcium levels for bone health -restrictions vary from 1000-3000 mg/d -limit high phosphorus foods such as convenience foods with added phosphorus, processed cheeses, red meats, dairy and colas Protein: -malnutrition is common at any stage -ensure patient meets daily protein needs without consuming excess -excess protein can increase the waste products in the body, making the kidneys work harder -Protein recommendations: -non-dialysis: 0.6-0.8 g/kg -peritoneal dialysis: 1.2-1.5 g/kg -hemodialysis: 1.2 g/kg -kidney transplant (4-6 weeks post): 1.3-2.0 -kidney transplant (>6 weeks post): 1.0 g/kg Fluid: -fluid retention can worsen in renal disease and result in fluid accumulation in the lungs and heart -can increase blood pressure and put strain on the kidneys to remove buildup of fluid -fluid restriction may be necessary even for patients on dialysis -fluid restrictions range from 800-2000 ml/day

-Rare genetic disorder that causes the amino acid phenylalanine to build up in the body -Phenylalanine is an essential amino acid needed for the synthesis of proteins, catecholamines, and melanin -Babies are screened for PKU soon after birth -Two types of PKU: 1. Classic PKU: more severe form, enzyme needed to convert phenylalanine to tyrosine is missing or severely reduced 2. Less severe forms of PKU: enzyme retains some function, phenylalanine levels are not as high, smaller risk of complications -If disorder is not treated, it can lead to serious health problems Symptoms: -no initial symptoms in newborns -Musty odor in breath, skin, or urine -Seizures -Skin rash (eczema) -Abnormally small head (microcephaly) -Intellectual disability -Delayed development -Behavioral and psychological problems Pathophysiology: -caused by a defect in the gene that creates the enzyme needed to break down phenylalanine -Without the enzyme necessary to process phenylalanine, a dangerous build up can develop when a person with PKU eats foods that contain protein or eats aspartame. Therefore, a special diet is required. Diagnosis: -Blood test performed from baby's heel when they're at least 24 hours old and after some protein has been ingested in the diet -If there is a positive result, additional testing may be necessary to confirm diagnosis, such as more blood or urine tests -Regular monitoring of phenylalanine levels are required. Goal is to keep between 1-6 mg/dL MNT: -During infancy, baby may consume breastmilk or a special baby formula, Lofenalac -Once solids are started, the diet involves limiting high protein, phenylalanine-containing foods, such as: -dairy, eggs, nuts, beans, chicken, pork, fish -Certain low-protein, PKU-friendly foods found at specialty health food stores can be consumed

Alcoholic Liver Disease
-The body can handle moderate intakes of alcohol, where it is efficiently metabolized and converted to fat -Chronic alcohol abuse displaces nutrients from the diet and interferes with the body's metabolism of nutrients Alcohol Metabolism: -Stomach: no digestion, quickly absorbed across the walls of an empty stomach, broken down by alcohol dehydrogenase -Small Intestine: absorbed rapidly into the small intestine, taking priority over most other nutrients -Liver: alcohol dehydrogenase oxidizes alcohol to acetaldehyde, which is then converted to acetate, which is then converted to either carbon dioxide or acetyl CoA "fatty liver": alcohol metabolism takes precedence over fat metabolism, and fat begins to accumulate and the liver deteriorates Malnutrition Concerns: -Folate and thiamin deficiencies -liver loses ability to retain folate, and kidneys increase excretion of it -alcohol interferes with action of folate converting homocysteine to methionine, resulting in excess homocysteine, a risk factor for heart disease -Wernicke-Korsakoff syndrome: alcohol-related thiamin deficiency characterized by paralysis of eye muscles, poor muscle coordination, and damaged nerves -Vitamin B6 deficiency -acetaldehyde dislodges vitamin B6 from its binding protein, resulting in deficiency and lower production of red blood cells -stomach cells over secrete gastric acid and histamine, an immune system agent that produces inflammation -intestinal cells fail to absorb thiamin, folate, and vitamin B12 -liver cells lose efficiency in activating vitamin D Spectrum of 3 Disorders: -Hepatic steatosis (fatty liver): condition of intrahepatic triglycerides making up at least 5% of liver weight. Occurs in 90% of chronic alcohol abusers -Alcohol hepatitis: toxic liver injury associated with chronic alcohol consumption -Alcohol cirrhosis Symptoms: -Alcohol fatty liver: mostly asymptomatic, lab abnormalities return to normal once patient is under treatment -Alcohol hepatitis: fever, jaundice, hepatomegaly, ascites, encephalopathy, portal hypertensive bleeding, increased susceptibility to infections such as pneumonia Diagnosis: -significant history of alcohol use -High AST/ALT ratio > 2 -Hepatomegaly -Liver biopsy or radiographic evidence showing steatosis or cirrhosis Pertinent Labs: Blood tests: -ammonia > 60 mcg/dL -cholesterol ester > 75% of cholesterol Urine tests: -bilirubin > 0 -urobilinogen > 4 mg/24 hours Pigment tests: -serum bilirubin > 0.9 mg: reflects livers ability to excrete bilirubin. Increased levels cause jaundice Enzymes: -Alkaline phosphatase > 95 U/L -GGT > 30 U/L -Aspartate transaminase (AST) > 40 U/L: detects hepatocellular injury secondary to cellular necrosis -Alanine aminotransferase (ALT)> 40 U/L: most sensitive test to detect hepatocellular injury secondary to exacerbation of infectious hepatitis MNT: -Healthy diet w/ fruits & vegetables and foods with anti-inflammatory nutrients -Avoidance of alcohol -Small, frequent meals -Multivitamin or B-complex vitamin -Educate patient on fat-restricted diet -2000 cals/d and 1.2-1.5 g/kg/d protein
