http://projects.csail.mit.edu/courseware/?term=random-acts-of-kindness-essay random acts of kindness essay 1 parenteral nutrition (pn), also called total parenteral nutrition (tpn), is the intravenous (iv) administration of fluids, macronutrients, electrolytes, vitamins, and trace elements for the purpose of weight maintenance or gain, to preserve or replete lean body mass and visceral proteins, and to support anabolism and nitrogen balance when the oral or que tal es el viagra enteral route is not feasible or adequate. Pn is a potentially lifesaving therapy in patients with intestinal failure but can be associated with significant complications. Desired outcomes and goals the goals of nutrition support therapy include. •• correction or avoidance of nutritional deficiencies •• weight maintenance (or weight gain in malnourished patients and growing children) •• preservation or repletion of lean body mass and visceral proteins •• support of anabolism and nitrogen balance and improvement of healing •• correction or avoidance of fluid and electrolyte abnormalities •• correction or avoidance of vitamin and trace element abnormalities •• improving clinical outcomes indications for pn pn can be a lifesaving therapy in patients with intestinal failure, but the oral or enteral route is preferred when providing nutrition support therapy. Compared with pn, enteral nutrition is associated with a lower risk of hyperglycemia and fewer infectious complications (eg, pneumonia, intra-abdominal abscess, catheter-related infections). 1–3 however, if used appropriately pn can be safe and effective and can improve nutrient delivery. Indications for pn are listed in table 100–1. 1,2 pn should be reserved for patients with altered intestinal function or absorption or when the gastrointestinal (gi) tract cannot be used. The anticipated duration of adequate pn therapy should be at least 5 to 7 days because shorter durations are unlikely to have a beneficial effect on a patient’s clinical and nutritional outcomes but may increase infection risk. 1,2 pn components pn should provide a balanced nutrition formula, including macronutrients, micronutrients, fluids, and electrolytes. Macronutrients, including amino acids, dextrose, and iv fat emulsions (ivfe), are important sources of structural and energy-yielding substrates. In a balanced pn formulation for adult patients, total daily calories are typically provided as 10% to 20% from amino 1489 1490  section 17  |  nutrition and nutritional disorders table 100–1  indications for parenteral nutrition in adults1,2 •• bowel obstruction •• physical or mechanical (eg, tumor compressing intestinal lumen) •• functional (eg, ileus, colonic pseudo-obstruction) •• major small bowel resection (eg, short-bowel syndrome) •• adult patients with < 100 cm of small bowel distal to the ligament of treitz without a colon •• adult patients with < 50 cm of small bowel if the colon is intact •• diffuse peritonitis •• intestinal fistulas if en cannot be provided above or below the fistula •• pancreatitis—if patients have failed en beyond the ligament of treitz or cannot receive en (eg, because of intestinal obstruction) •• severe intractable vomiting •• severe intractable diarrhea •• preoperative nutrition support in patients with moderate to severe malnutrition who cannot tolerate en and in whom surgery can be delayed safely for at least 7 days •• in critically ill patients without malnutrition who cannot receive oral or en in the first 7 days of icu admission, pn should only be initiated after the first 7 days of admission and if oral or en is still not feasible acids, 50% to 60% from dextrose, and 15% to 30% from ivfe. Amino acids may provide more than 20% of the total daily calories in patients with conditions that increase protein requirements (eg, severe thermal injury, healing wounds, cachexia, treatment with continuous renal replacement therapy, hypocaloric feeding). Electrolytes and micronutrients, including vitamins and trace elements, are required to support essential biochemical reactions. Patients require individual adjustments of pn components based on their nutritional status, nutritional requirements, underlying disease state(s), level of metabolic stress, clinical status, and organ functions. Macronutrients »» amino acids amino acids, the building blocks of proteins, are an essential component of pn admixtures. Amino acids are provided to preserve or replete lean body mass and visceral proteins, to promote protein anabolism and wound healing, and as a source of energy. Amino acids have a caloric value of 4 kcal/g (17 kj/g). Parenteral crystalline amino acid solutions are supplied by various manufacturers in various concentrations (eg, 7%, 8%, 8. 5%, 10%, 15%, and others). Different formulations are tailored for specific age groups (eg, adults, infants) and disease states (eg, kidney or liver dysfunction). Specialized formulations for patient encounter, part 1 pg is a 59-year-old man with a history of hypertension and colon cancer, status post colon resection and colostomy, followed by chemotherapy, and subsequent colon reanastomosis. He was admitted approximately 2 weeks ago with signs and symptoms consistent with a bowel obstruction. He was taken to the or for an exploratory laparotomy and found with multiple adhesions causing small bowel obstructions in two locations. He underwent a small bowel resection (jejunum) and extensive lysis of adhesions, and he was discharged 8 days ago. Pg is readmitted with foul-smelling drainage from his surgical incision for 2 days along with nausea, decreased appetite, and decreased oral intake for the past 2 to 3 days. Since his diagnosis of colon cancer he has had weight loss, poor oral intake, and malnutrition. Most recently with his bowel obstructions and current symptoms, he reports an unintentional weight loss of about 10 lb (4. 5 kg) over the past 4 to 5 weeks. Pmh.

However, other herbal supplements with potentially serious adverse cardiovascular effects remain easily accessible. Some herbal supplements, such as feverfew and garlic, may interact with antiplatelet and antithrombotic therapy and increase bleeding risk. Dietary supplements purported to enhance sexual performance may contain phosphodiesterase-like chemicals and increase risk for serious hypotension with nitroglycerin. Other agents may reduce the effectiveness of antianginal medications, such as st. John’s wart with ranolazine. Thus, it is important to assess the use of herbal products in patients with ihd and to counsel patients about the potential for drug interactions and adverse events with herbal therapies. Cyclooxygenase-2 inhibitors and nonsteroidal antiinflammatory drugs data suggest that cyclooxygenase-2 (cox-2) inhibitors and nonselective nsaids may increase the risk for mi and stroke. 48 the cardiovascular risk with cox-2 patient encounter part 3. Creating a care plan based on the information presented, create a specific plan for the management of the patient’s ischemic heart disease. Your plan should include (a) the goals of therapy, (b) specific nonpharmacologic and pharmacologic interventions to address these goals, and (c) a plan for follow-up to assess drug tolerance and whether the therapeutic goals have been achieved. Inhibitors and nsaids may be greatest in patients with a history of, or with risk factors for, cardiovascular disease. The cox-2 inhibitors rofecoxib and valdecoxib were withdrawn from the market because of safety concerns. Product labeling for other cox-2 and nonselective nsaids (prescription and over-thecounter) now includes boxed warning about potential adverse cardiovascular effects. The aha recommends the use of cox-2 inhibitors be limited to low-dose, short-term therapy in patients for whom there is no appropriate alternative. 48 patients with cardiovascular disease should consult a clinician before using over-the-counter nsaids. Special populations variant angina vasospasm as the sole etiology of angina (prinzmetal or variant angina) is relatively uncommon. As a result, treatment options are not well studied. Nevertheless, based on the pharmacology of available drugs, several recommendations can be made. First, β-blockers should be avoided in patients with variant angina because of their potential to worsen vasospasm due to unopposed α-adrenergic receptor stimulation. In contrast, both ccbs and nitrates are effective in relieving vasospasm and are preferred in the management of variant angina. Because nitrates require an 8- to 12-hour nitrate-free interval, their role as monotherapy for prophylaxis of anginal attacks due to vasospasm is limited. However, immediate-release nitroglycerin is effective at terminating acute anginal attacks due to vasospasm. Therefore, all patients diagnosed with variant angina should be prescribed immediate-release nitroglycerin. Ccbs are effective for monotherapy of variant angina. Because short-acting ccbs have been associated with increased risk of adverse cardiac events, they should be avoided. 41 long-acting nitrates may be added to ccb therapy if needed. Microvascular angina there are limited data on optimal therapy in patients with microvascular disease. Both ace inhibitors and statins may produce beneficial effects on endothelial function and improve microvascular angina. 4 short-acting nitrates remain the treatment of choice for relieving acute symptoms, although they may be less effective in microvascular disease. Similar to obstructive cad, β-blockers are first line to control symptoms of angina in patients with microvascular disease and may be more effective than ccbs and long-acting nitrates in this setting.

Spontaneity and uency o speech output ability to repeat spoken words/sentences comprehension naming o objects reading writing expression and comprehension a pha s ia what are the different kinds of classical aphasias described?. The aphasias x in the ollowing section, we will discuss the main types o aphasia seen in the clinical setting, their clinical mani estations, and their localization.2,4,6 each will be de ned by their per ormance in the domains o (1) uency, (2) ability to repeat, and (3) comprehension o language (see algorithm in figure 23-3). T eir localization and related co-occurring clinical mani estations will also be discussed, and examples o types o actual de cits seen will be given. T e aphasias will be subdivided into anterior (expressive) and posterior (receptive) aphasias. T e transcortical aphasias are distinguished rom the classical expressive or receptive aphasias in the preserved ability to repeat because the primary cortical (broca’s and wernicke’s areas) and subcortical (arcuate asciculus) structures thought to be necessary or repetition remain intact. T ey are conceptualized as involving the areas o the cortex surrounding the primary language areas, thereore partially isolating or disconnecting the language areas rom other parts o the brain. Anterior aphasias x broca’s aphasia fluency is impaired. T is is mani ested by varying degrees o impaired expression o words. Depending on the size and area o the lesion, clinical mani estations can range rom a complete inability to speak to a halting speech with impaired grammar, syntax, naming, and assembly o phonemes. For example, in the most severe cases, a patient may be mute, or only be able to utter vowel-type sounds. In less severe cases, syntax and grammar are impaired, and speech becomes “telegraphic” as it may lack conjunctions (and, but, or), prepositions (on, to, rom), auxiliary verbs (have, is), plurals, or tenses o verbs. In other cases, there is simply a lack o ow o speech with requent halting, paraphasic (usually phonemic) errors. T ey have dif culty “in both the assembly o phonemes into words, and the assembly o words into sentences.”2 speech is labored and slow.
