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: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: altered mental status major surgical or invasive procedure: intubation central line placement arterial line placement history of present illness: this is an 88 year old male with history of gastric ca, ckd htn, mental retardation (non-verbal at baseline) who was admitted for weakness and lethargy and found to have e.coli uti. today he presents from his nursing home where he was found to have altered mental status with a bp of 144/85 and hr 150. he had been vomiting the previous day. . in the ed, initial vs were t:99.1 bp:116/72 hr: 176 rr: 24 o2sat: 98%nrb. blood pressure reportedly dipped to systolics in 70's. he was found to be in afib and cardioverted to sinus which returned to afib. given rr of 48 and hypoxia to the 70's he was intubated. sepsis line in rij placed and levophed started. got vanc and zosyn. ct abdomen concerning for ischemic gut. lactate initially 8 resolved to 4 with ivf. surgery was consulted wished to speak with family to gauge goals of care. also given bicarb, tylenol, fentanyl/versed gtt, kayexalate for hyperkalemia. he received 6 liter of ivf. . past medical history: hypertension aspiration gerd dysphagia arthritis renal insufficiency -- baseline cr not documented "stomach cancer" hypothyroidism mental retardation: type unknown, nonverbal at baseline injury to back-- was wearing brace until arthritis social history: lives at healthcare center. previously was living in a group home. no known alcohol or tobacco use. family history: non-contributory physical exam: vitals - t:99 bp:131/58 hr:120 rr:36 02 sat:99% general: intubated, sedated heent: nc/at, perrl, mmm cardiac: s1/s2 present, no murmurs lung: anterior lung fields clear abdomen: no bowel sounds, firm, +guarding r>l gi: foley in place, +hematuria ext: feet cool, no le edema, no mottling neuro: sedated derm: no skin lesions pertinent results: admission

lactate-8.0* k+-5.0 ========= microbiology : stool: + cdiff toxin blood cultures: pending sputum cx: pending urine: negative ========= ecg: probable multifocal atrial tachycardia. low limb lead qrs voltage. left axisdeviation may be due to left anterior fascicular block and/or possible prior inferior myocardial infarction. delayed r wave progression with late precordial qrs transition is non-specific. since the previous tracing of there is probably no significant change. ========== imaging: cxr: indwelling devices are unchanged in position, and cardiomediastinal contours are stable in appearance. worsening opacity in left retrocardiac region is likely due to a combination of atelectasis and small pleural effusion, but infectious pneumonia should also be considered in the appropriate clinical setting. ct torso: 1. no evidence of pulmonary embolism or dissection. aneurysm of the ascending aorta. trace pericardial fluid. 2. dilated, ahaustral, and hypoenhancing segments of the sigmoid colon with bowel wall thickening and adjacent fat stranding, concerning for infectious process, less likely ischemia. 3. enlarged prostate with prostatic stent. foley catheter ends proximal to stent with balloon inflated within the prostate. 4. small atrophic bilateral kidneys. brief hospital course: 88 yo male presenting with altered mental status, hypotension and hypoxia. patient required emergent intubation, central line placement, and initiation of pressors in emergency department. a ct abdomen showed thickening of the sigmoid colon with surrounding fat stranding suggesting inflammatory process. on exam abdomen was distended and guarded. given high suspicion for cdiff he was given po vancomycin and iv flagyl. patient was seen and evaluated by the general surgical service. the surgical team discussed option of surgical intervention with the health care proxy who ultimately decided that surgery was too aggressive. hcp decided on dnr/dni code status. the patient was admitted to the micu where he was aggressively hydrated and continued on vasopressor support (a total of 3 vasopressors were eventually needed). hemodynamics were further complicated by mat for which he was started on iv amiodarone. despite aggressive fluid resucitation and eventual initiation of a total of three vasopressors patient remained hypotensive with a rising lactate. hcp decided on comfort measures at which time vasopressor support was stopped and patient died soon after. his hcp requested an autospy be performed. notably, clostridium difficile toxin returned positive. medications on admission: polyvinyl alcohol-povidone 1.4-0.6 % dropperette : 1-2 drops ophthalmic q 8h (every 8 hours). levothyroxine 125 mcg tablet : one (1) tablet po daily (daily).
