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: admission history and physical: mr. is a year old male with a past medical history of aortic stenosis and hypertension who had been in a generally reasonable functional state prior to presentation. he presented on with repeat episodes of bright red blood per rectum and some abdominal pain for which he was admitted to the medical service. he had already been scheduled for a prior colonoscopy. at the time of his admission, he had not had any notable fevers, no trauma to the abdomen and no hematemesis. his temperature was 99.1 and he was otherwise hemodynamically stable with an oxygen saturation of 96 percent. he wasn't in any distress on admission. his lungs otherwise had rales at the bases, but his heart was regular. his belly was soft. he had a mild amount of tenderness in the right and left lower quadrant, but otherwise no rebound or guarding. his admission white count was 8.3 with hematocrit of 34 and notably had 35 percent bands. his bun and creatinine were 25 and 0.9 respectively. his ekg showed t- wave inversion in lead iii which was new. hospital course: the patient was admitted to the medical service and started on antibiotics which included levofloxacin and flagyl for his bandemia and underwent a ct scan which showed some nonspecific circumferential thickening of the sigmoid colon. he therefore underwent his sigmoidoscopy with a variable colonoscope on . this was a limited exam of the left colon due to lack of bowel preparation but blood was noted in the colon with significant diverticulosis. postoperatively, the patient continued to have significant abdominal pain and on further workup, was found to have free air in the peritoneum and therefore there was concern for colonic perforation. as the patient's clinical status deteriorated, the surgical service was consulted and a decision was made to take the patient to the operating room given the fact that he had evidence of peritonitis with free air under the diaphragm indicating likely colonic perforation with gross spillage of stool. there was concern that he had had myocardial infarction, but given the fact that his septic state would not improve without surgery after consultation with general surgery, colorectal surgery and gastroenterology, it was decided that the patient should be taken to the operating room. on , he underwent a left colectomy with a hartmann's pouch and a transverse colostomy. intraoperatively, it was noted that the descending colon was markedly inflamed and thickened. there was no evidence of a tumor. this was subsequently sent for pathology and showed evidence of colitis, but no other malignancy. the patient postoperatively was taken to the intensive care unit where he remained for the duration of his hospitalization. neurologically, the patient remained mentally alert. his pain was controlled with a variety of narcotics. there were no other issues. in terms of his respiratory status, the patient developed pulmonary edema postoperatively secondary to large fluid requirements and some cardiac insufficiency. these were complicated by pleural effusions and what appeared to be an ards picture. although attempts were made to wean him off the ventilator with aggressive diuresis and various ventilator management strategies, the patient was never able to wean to extubation. in terms of his cardiovascular issues, after his initial myocardial infarction, the patient continued to have a mild troponin leak. we attempted to optimize his cardiac status medically, but the patient did require significant vasopressors including levophed to maintain his blood pressure. a variety of combinations of pressors were used including dobutamine to augment the patient's cardiac output. management of this was facilitated by the use of a swan-ganz catheter. during the course of the patient's hospitalization, he began to experience repeated episodes of nonsustained ventricular tachycardia. these never did progress to a sustained ventricular tachycardia or ventricular fibrillation. the patient's initial problem of his colonic perforation was managed appropriately with his colectomy and transverse colostomy. unfortunately, secondary to the patient's poor nutritional status and his gross infection, his wound dehisced on postoperative day 8 at which time he was subsequently taken back to the operating room and re- explored and repaired. a vac dressing was subsequently applied to facilitate with wound closure. the patient had significant hyperbilirubinemia. a right upper quadrant ultrasound was performed, but there wasn't any evidence of cholecystitis or bile duct obstruction and it was felt to be secondary to his septic state and cholestasis. renally, the patient continued to progressively develop acute renal insufficiency with rising creatinine which at the time of his death was twice his baseline. hematologically, the patient did have an anemia secondary to a combination of blood loss, malnutrition and volume. he required multiple transfusions for this. he also had thrombocytopenia which stabilized. there was no evidence of heparin-induced antibodies.the patient's most critical issues included his infectious disease issues. he suffered from a series of pneumonias which included albicans. his peritoneal fluid grew out gram- negative rods which included e. coli and were consistent with feculent material. otherwise, his most serious issue was candidemia. the patient was found to have multiple episodes of albicans growing on blood cultures even after his vascular access lines had been changed. given this poor prognostic sign, a meeting took place with the family to determine the patient's overall status and goals for treatment. it was felt at this time, given his respiratory failure, his septic state, his adrenal insufficiency, his renal failure and his candidemia, that the patient should be made a do not resuscitate, but the family wanted to continue all aggressive medical care which the icu team agreed to. attempts at optimizing his medical status were continued for one week after the time of making the patient do not resuscitate, but the patient failed to improve. given his failure to improve and grim prognosis, it was decided by the family to make the patient comfort measures only which was done on . the patient expired at hours on with the final cause of death being respiratory arrest. , procedure: continuous invasive mechanical ventilation for 96 consecutive hours or more parenteral infusion of concentrated nutritional
