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: amoxicillin / cephalosporins / penicillins attending: chief complaint: fever major surgical or invasive procedure: none history of present illness: the patient is an 84 y.o. male nursing home resident who was febrile to 103 and hypotensive to 80/56 on the morning of ; he had no specific complaints at that time. on arrival to an osh ed, he remained febrile (104) and hypotensive (80/56). he was given iv fluids, started on vasopressin, and was sent to the icu. in the icu, peripheral dopamine was added; he then achieved a bp of 105/49. he was awake, alert, and complaining of abdominal pain. his exam was notable for mild llq pain with a palpable mass; there was no rebound or hypoactive bowel sounds. his labs showed wbc of 9000 with 41% pmns and 51% bands, hct 28% (from 30 earlier this month), lactate 2.8, ast 233, alt 164, alk phos 767, total bili 2.8, direct bili 1.1, amylase 45, creatinine 2.4 (baseline 1.7 earlier this month), and troponin-i 0.71. his u/a was unremarkable save 150 mg protein/dl. a bedside ruq u/s was of limited quality due to patient movement but did show cbd dilatation (12 mm). he was given aztreonam mg iv, metronidazole 500 mg iv, vancomycin 1000 mg iv, levofloxacin 500 mg iv, and hydrocortisone 100 mg iv. blood cultures were drawn and promptly grew gram negative rods in 4 out of 4 bottles. he was then transferred to the . . here an incomplete kub showed a non-obstructive bowel gas pattern; the lower abdomen and pelvis were excluded from view. cxr showed increased interstitial markings bilaterally and no pleural effusions. a retrocardiac density was though to represent atelectasis, but a focal area of consolidation was not excluded. past medical history: 1. bipolar disorder/depression with psychotic features 2. diabetes mellitus type 2 3. hypothyroidism 4. chronic kidney disease (baseline creatinine 1.7) 5. bph 6. osteoarthritis 7. lung nodule social history: there is no known history of alcohol or tobacco use or abuse. he is a resident of the nursing home in . he is able to feed himself. . family history: non-contributory physical exam: t 96.3 bp 126/78 hr 85 rr 25 sat 94% on 5l n.c. gen: elderly man lying in bed with eyes closed and mouth open;

no large stone or biliary tree strictures were seen. there were no evidence of extrinsic compression, no ductal abnormalities, and no large filling defects. the cystic duct did not fill, due to either obstruction or the use of low pressure contrast injection. a biliary stent was placed. . a post-ercp right upper quadrant ultrasound shows gallstones and a contracted gall bladder but no other abnormalities. . serial cxrs have shown the evolution of moderate pulmonary edema that has been stable for 24 hours; there are also small bilateral pleural effusions, greater in the left, that are also stable. the left lower lobe retrocardiac opacity persists. . clinically, the patient was weaned off of vasopressors on the day of arrival in the . he has remained hemodynamically stable, and his urine output has been excellent. he has been vigorously hydrated with iv fluids. he was treated with vancomycin, aztreonam, ciprofloxacin, and metronidazole on admission. once the gram-negative rod was identified as a quinolone-resistant e. coli, his ciprofloxacin was stopped (yesterday afternoon); stress-dose steroids (hydrocortisone 100 mg iv q8h) as well as his baseline fludrocortisone were started on admission and have been continued. . he currently feels tired from being disturbed all day but otherwise denies focal complaints. in particular, he denies headache, chest pain, dyspnea, cough, abdominal pain, n/v, diarrhea, myalgias, or arthralgias. after meeting with patient and family patients plan of care was changed to comfort measures only. plan to transition to hospice care at . medications on admission: 1. paroxetine 10 mg daily 2. levothyroxine 75 mcg daily 3. mirtazipine 30 mg qhs 4. fludrocortisone 0.1 mg daily 5. mvi 6. lactulose 30 cc 7. insulin 70/30 18 units qam discharge medications: 1. levothyroxine 75 mcg tablet sig: one (1) tablet po daily (daily). 2. paroxetine hcl 10 mg tablet sig: one (1) tablet po daily (daily). 3. mirtazapine 30 mg tablet sig: one (1) tablet po hs (at bedtime). 4. olanzapine 5 mg tablet, rapid dissolve sig: one (1) tablet, rapid dissolve po qhs (once a day (at bedtime)). 5. bisacodyl 5 mg tablet, delayed release (e.c.) sig: two (2) tablet, delayed release (e.c.) po daily (daily) as needed. 6. haloperidol lactate 5 mg/ml solution sig: 0.5 mg injection tid (3 times a day) as needed. 7. lactulose 10 g/15 ml syrup sig: thirty (30) ml po q8h (every 8 hours) as needed for constipation. discharge disposition: extended care facility: nursing center - discharge diagnosis: congestive heart failure hypernatremia cholecystitis discharge condition: stable, cmo discharge instructions: continue medications as needed for comfort. followup instructions: 1. follow up with pcp as needed. procedure: venous catheterization, not elsewhere classified venous catheterization, not elsewhere classified venous catheterization, not elsewhere classified parenteral infusion of concentrated nutritional substances endoscopic insertion of stent (tube) into bile duct transfusion of other serum irrigation of other indwelling urinary catheter infusion of vasopressor agent diagnoses: acidosis anemia in chronic kidney disease acute posthemorrhagic anemia acute kidney failure, unspecified unspecified protein-calorie malnutrition severe sepsis unspecified acquired hypothyroidism acute myocardial infarction of other anterior wall, initial episode of care hypertrophy (benign) of prostate without urinary obstruction and other lower urinary tract symptom (luts) hypertensive chronic kidney disease, unspecified, with chronic kidney disease stage v or end stage renal disease hemorrhage complicating a procedure pneumonitis due to inhalation of food or vomitus long-term (current) use of insulin diabetes mellitus without mention of complication, type ii or unspecified type, uncontrolled acute systolic heart failure hyperosmolality and/or hypernatremia septicemia due to escherichia coli [e. coli] cholangitis bipolar disorder, unspecified other and unspecified coagulation defects legal blindness, as defined in u.s.a.
