Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: history of present illness: this patient is a 72-year-old male, who was recently admitted to hospital from to for acute mesenteric ischemia for which he had status post aortobifemoral bypass graft for an occluded mesenteric vasculature with dead bowel. he also underwent a massive small bowel resection with jejunocolostomy during that hospital visit. this was followed with ileocecectomy and ileocolostomy, and a percutaneous cholecystostomy tube, a peg/j tube and a left subclavian hickman for long-term tpn. his previous hospital course was complicated by anastomotic ulcer with significant bleeding. the bleeding had subsequently subsided over a period of time. the patient was then discharged to rehab after prolonged hospital course, but now returns with significant dehydration, azotemia, sepsis, abdominal pain, and a low-grade temperature of 100.3. he also had leukocytosis, and on initial ct scan, there was presumed small bowel obstruction at the small bowel - colon anastomosis. patient was brought in urgently for hydration and exploratory laparotomy. past medical history: 1. acute mesenteric ischemia. 2. anastomotic ulcer/bleed. 3. history of mrsa. 4. history of enterobacter/klebsiella septicemia. 5. significant 60-pack year smoking history. past surgical history: 1. aortobifemoral/superior mesenteric artery bypass graft. 2. small bowel resection. 3. left subclavian double lumen hickman. 4. status post ileocecectomy/ileocolostomy. 5. status post cholecystostomy tube. 6. status post peg-j tube. 7. remote status post vasectomy. medications on admission: 1. levaquin 500 mg q.d. 2. lopressor 12.5 mg b.i.d. 3. ursodiol 300 mg t.i.d. 4. protonix 40 mg b.i.d. 5. loperamide 2 mg b.i.d. 6. iron sulfate 5 mg b.i.d. 7. morphine sulfate p.o. 10-15 mg q.4-6h. prn. 8. mucomyst nebulizer. 9. chlorhexidine 15 mg q.3h. prn. 10. insulin-sliding scale. allergies: no known drug allergies. laboratory data on admission: wbc 21.4, hematocrit 29.9, platelets 247. sodium 154, potassium 3.8, chloride 125, bicarb 16, bun 74, creatinine 1.8, glucose 72. alt 96, ast 92, alkaline phosphatase 318. amylase 23, total bilirubin 9.9, lipase 11. ct of the abdomen and ct angiogram: small bowel obstruction with distention of the small bowel, edema of the small bowel wall, most likely at the ileocolonic anastomotic site. distended gallbladder with gallbladder wall edema. ascites. patent superior mesenteric artery graft. hospital course: patient was admitted on and immediately went to the operating room for an exploratory laparotomy. in the or, a exploratory laparotomy with a midline incision was performed, along with a cholecystectomy, and g tube placement. a small bowel resection with jejunocolostomy was also performed, and a diagnosis of bile peritonitis was confirmed in the or. the patient tolerated the procedure, remained in hypovolemic/septic shock following the operation. he was transferred to the surgical icu for further management of his hypovolemia, azotemia, and sepsis. he was placed on broad-spectrum antibiotics including vancomycin, levofloxacin, flagyl, and fluconazole. during his or and initial icu course, he received 8 units of packed red blood cells, 4 units of ffp, and over 5 liters of crystalloid. he had an estimated blood loss of 2 liters in the or. he was maintained on a levophed drip. over the next couple of days, the patient was given massive fluid resuscitation along with ffp and vitamin k. he was kept intubated and sedated. during his hospitalization, the vascular surgery service was also made aware of his presence. they had formally evaluated while in the emergency department, and followed him throughout his hospital course. they felt that he demonstrated no evidence of acute ischemia during his present hospital course. this patient had blood cultures, sputum cultures, and peritoneal cultures all which demonstrates methicillin-resistant staphylococcus aureus. by , the patient was finally weaned off his levophed. he remained hemodynamically stable throughout the rest of his icu course. he was continued on broad-spectrum antibiotics. patient was also started on tpn with the help of a nutritional consult. he was also started on tube feeds and advanced slowly to a goal of 30 cc an hour of full strength impact with fiber. on , the patient was started on diuresis of his fluid overload. on , a right upper extremity ultrasound was obtained for right upper extremity swelling. this ultrasound demonstrated a nonocclusive thrombus of the right internal jugular vein. the patient was started on a heparin drip of 400 units per hour with a goal of 40-60 ptt. on , the patient developed diarrhea, clostridium difficile was sent, which returned negative. on , the patient was finally extubated and patient was tolerating goal tube feeds and cpm. he was transferred to the vicu on . he received aggressive chest pt. he was finally transferred to floor status on , and also underwent a second ultrasound, which did not reveal any deep venous thrombus particularly of the right internal jugular vein. his heparin was stopped, and the patient was also taken off all antibiotics by . a bedside swallow study was performed, and the patient was determined to be a clear aspiration risk. as a result, he was maintained at npo status, and was continued on tube feeds with a plan for long-term tpn. home tpn service and dr. office was contact for future planning of home tpn. patient's foley was also discontinued, and he successfully passed his voiding trial. physical therapy and occupational therapy were both consulted, and patient was screened for rehab. patient remained hemodynamically stable, and remained afebrile throughout the rest of his hospital course. he was set for discharge by . discharge status: rehab facility. discharge condition: good. discharge diagnoses: 1. bile peritonitis. 2. small bowel obstruction status post small bowel resection. 3. cholecystitis status post cholecystectomy. 4. status post gastrostomy tube placement. follow-up instructions: patient is to followup with dr. within two weeks. patient is to call to make an appointment. patient is also to be followed up for video swallowing test to assess for his aspiration potential within 2-3 weeks. patient is also to be setup for home tpn services. discharge medications: 1. ranitidine 150 mg b.i.d. per g tube. 2. lopressor 25 mg b.i.d. per g tube. 3. insulin-sliding scale. 4. impact with fiber full strength tube feeds should run at 30 cc an hour. 5. tpn should entail the following volume cc/hour. 6. amino acid 100 grams. 7. dextrose 250 grams, 45 grams per day of fat. 8. potassium chloride 30 mmol/l. 9. potassium phosphate 30 mmol/l. 10. magnesium sulfate 10 mmol/l. 11. calcium gluconate 15 mmol/l. 12. zinc 10 mg. other instructions: patient should remain npo. he should receive tube feeds at 30 cc an hour, and maintained with daily tpn. all medications should be given through g tube or by subq injection. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified continuous invasive mechanical ventilation
