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: the patient was an 83-year-old female with a past medical history notable for ischemic bowel status post total colectomy and resection of one-third of her small bowel in , cholecystectomy for acute cholecystitis in , vre uti, coronary artery disease status post rca stent x 2, and a non-st elevation mi in , with a recent hospitalization in . in , the patient had urosepsis and pneumonia. she presented on the day of admission to the after being found unresponsive to the nursing home. per ems records, she was found lethargic and cyanotic with cold extremities on rounds there. her heart rate was in the 40s. respiratory rate was in the 30s. blood pressure was in the 50s systolic. upon presentation to the , she received approximately 9 l of intravenous fluids, 3 units of packed red blood cells and was placed on levophed drip. she was also started on broad-spectrum antibiotics in the form of vancomycin, imipenem and flagyl. she was sedated, intubated and transferred to the surgical icu with 500 cc of red brown output. past medical history: ischemic bowel, short-gut syndrome, acute cholecystitis, vre uti, klebsiella uti, hypertension, copd, cad status post 2 stents to the rca, non-st elevation mi in . past surgical history: total colectomy, cholecystectomy, thyroidectomy. allergies: ace inhibitor. medications: aspirin 325, lipitor 10 mg p.o. daily, lopressor 25 mg p.o. b.i.d., atrovent nebulizers, albuterol nebulizers, prilosec, ranitidine, ambien, maalox, flovent. physical examination: vital signs: temperature 97.8, the lowest being 90, heart rate 144, blood pressure 99/43 on levophed and pitressin drips, respiratory rate 12, 92% on maximal ventilator support, fio2 100% assist-control ventilation. general: she was minimally responsive. abdomen: ostomy had dark red blood. the abdomen itself was soft, distended and relatively firm. laboratory data: white blood cell count 32,000, hematocrit 40.9, 93% neutrophils; creatinine 1.5. hospital course: the patient was admitted to the intensive care unit. the remainder of this dictation will be presented in a system space format. neurologic: she was sedated using fentanyl. head ct scan was obtained which revealed a questionable small frontal infarct but no other mass or lesion. cardiovascular: she required maximal support with levophed and pitressin throughout the intensive care unit admission to maintain her support. respiratory: she required assist-control ventilation. she developed an ards picture with an fio2 requirement of 100%. this was gradually weaned through her intensive care stay. gi: she was maintained npo and started on total parenteral nutrition. gu: in consultation with the renal service, the patient's renal status was reasonable. initially she had some polyuria, but her urine status seemed to normalize. she also had a significant lactic acidosis which only mildly improved. hematologic: the patient required transfusions of platelets for a low platelet count. hematology/oncology service was also consulted for her thrombocytopenia. ffp was given for a mild coagulopathy with elevated pt and inrs. infectious disease: she was kept on vancomycin, imipenem and flagyl. she had no obvious source of infection, although her urine did have e. coli. the ostomy output continued to be slightly bloody throughout the admission. tubes, lines and drains: she had a central catheter inserted by the surgical intensive care team. prophylaxis: she was placed on protonix. a hit panel was sent which was negative, although her platelets remained low throughout the admission. endocrine: she was maintained on insulin drip for proper glycemic control. the patient's electrolytes were followed closely, and she maintained on maintenance fluid for hydration. the patient's status did not improve as the admission progressed despite maximal vasopressor support. after a detailed discussion between the attending surgeon and the healthcare proxy, it ws decided to make the patient comfort measures only. on , the vasopressor support was stopped. the patient was made comfortable with morphine and fentanyl. she expired at 1:13 p.m. on . , procedure: venous catheterization, not elsewhere classified continuous invasive mechanical ventilation for 96 consecutive hours or more parenteral infusion of concentrated nutritional substances insertion of endotracheal tube transfusion of packed cells transfusion of packed cells transfusion of other serum transfusion of platelets phlebography of other specified sites using contrast material infusion of vasopressor agent diagnoses: urinary tract infection, site not specified congestive heart failure, unspecified intestinal bypass or anastomosis status unspecified septicemia severe sepsis chronic airway obstruction, not elsewhere classified percutaneous transluminal coronary angioplasty status acute respiratory failure defibrination syndrome other shock without mention of trauma old myocardial infarction hemorrhage of gastrointestinal tract, unspecified other and unspecified postsurgical nonabsorption ileostomy status unspecified vascular insufficiency of intestine
