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: miss is an 80-year-old female with multiple medical problems who was transferred to from hospital in for management of her gi bleeding. the patient is a resident of nursing home in , , who presented to her local community hospital with melenic stool. in the hours preceding admission to the community hospital, the patient was evidently poorly responsive and appeared ill enough that the family and staff expected her to expire. ultimately they debated pros and cons of allowing transport to the hospital and the husband consented to have her brought to the hospital with the idea that comfort measures would take priority. upon admission the patient was treated conservatively with intravenous fluids and packed red blood cells. in addition, her do not resuscitate was continued. the patient was evaluated by gastroenterology who performed both an upper endoscopy and a sigmoidoscopy that demonstrated no obvious source of bleeding. she did have a tag red blood cell scan that evidently demonstrated bleeding from the area of the right colon. after further discussions with the family, the patient was apparently transferred to for angiography and possibly vasopressin therapy to control her gastrointestinal bleeding. past medical history: gastrointestinal bleed secondary to diverticular disease, anemia, coronary artery disease with a history of mi, history of atrial fibrillation, alzheimer's dementia with oral dyspraxia, depression, hypertension, hyperlipidemia, questionable history of tia. past surgical history: notable for status post cabg in , status post left carotid endarterectomy in , status post tah bso, status post bilateral mastectomy secondary to fibrocystic disease, kidney stone removal. physical examination: the patient was noted to be a pleasant, elderly female who was sleepy but easily arousable. heart had a regular rate and rhythm with no murmurs, rubs or gallops. chest had coarse breath sounds bilaterally. she was clear to auscultation. abdomen was soft with quiet bowel sounds. she was nontender, non distended. her extremities were without clubbing, cyanosis or edema. medications: at the nursing home she receives the following medicines: iron, erythromycin eye ointment, morphine prn, nitroglycerin prn, pravachol 30 mg q day, coumadin which is currently being held, aspirin which is currently being held, digoxin 0.25 mg po q day, prinivil 5 mg po q day, aricept 5 mg po q day, lasix 80 mg po q day, ritalin 5 mg po q day, potassium 20 meq po bid, multivitamin, b complex. questionably allergic to pepcid. hospital course: on the patient was transferred to the medicine team at from hospital for continued management of her gi bleed. at hospital she had required 10 units of packed red blood cells and 4 units of ffp. her coumadin and aspirin had been discontinued. she had had multiple tests including upper endoscopy and colonoscopy that revealed diverticulosis with no obvious source of bleeding and a red blood scan remarkable for a source of bleeding in the right lower quadrant. the patient was transferred to with the idea of having angiography and possible vasopressin therapy. on the second day of the patient's hospitalization she was taken to the angiography suite for vascular imaging of her gastrointestinal tract and vasopressin infusion. the family understood that the vasopressin infusion to be administered in the absence of acute extravasation was not standard therapy and that the patient would require a concomitant nitroglycerin drip as she has a positive cardiac history. family also understood that this was an unusual approach and is likely not done at other facilities. given that the patient had failed conservative therapy and the blood loss was too frequent to permit pure observation, plan was made to admit the patient to the medical icu and initiate vasopressin therapy under intensive cardiac monitoring. therefore, patient was taken to the angiography suite where the interventional radiology team performed a mesenteric angiogram and initiated an intra-arterial vasopressin therapy. she had a diverticular bleed that was identified and treated with vasopressin of 0.1 mcg/min. however, while the patient was in the interventional radiology suite, rebleeding was observed and her vasopressin dose had to be increased to 0.2 units per minute. during this time she did receive intravenous nitroglycerin to protect her myocardium and she was observed for signs and symptoms of both mesenteric and cardiac ischemia. at the time of angiography, it appeared that patient's gi hemorrhage was controlled with the intra-arterial vasopressin and it was continued at 0.15 units per minute followed by decrease to 0.1 unit per minute to be continued through the night. by the patient's third hospital day her vasopressin was discontinued. during this time she had required a transfusion with a total of 5 units packed red blood cells. the patient was observed over the following hospital days for any evidence of re-bleeding. over the ensuing days the patient's hematocrit continued to trend downward and after she had been transferred from the medical intensive care unit she was observed to have another episode of melena. the patient was still without a clear source of bleeding and for this reason her upper endoscopy was repeated, revealing only gastritis. she had another tag red blood cell scan demonstrating bleeding that appeared to originate from the right colon. the interventional radiology team re-evaluated her, noted that the bleeding appeared similar to the tag red blood cell scan obtained at hospital and likely represented a recurrent diverticular bleed in the region of the cecum or proximal ascending colon. they concluded that the interventional radiology therapeutic options included embolization or vasopressin treatment, however, due to the patient's extensive atherosclerotic mesenteric disease, she was not a candidate for transcatheter embolization as it put her at an unacceptable risk for bowel infarction. in addition, repeat vasopressin therapy was also felt to be very high risk due to her cardiac status and that her first treatment proved to be unsuccessful. at this point it was felt that the only viable option was surgical intervention. cardiology team was asked to evaluate her preoperatively. they acknowledged that she was a high risk surgical candidate and recommended that she be started on intravenous lopressor for its cardioprotective effects. in addition, they recommended that her digoxin be continued, that she be prophylaxed with antibiotics against bacterial endocarditis and that close monitoring be implemented to assess her fluid balance peri and postoperatively. on , the 8th day of the patient's hospitalization, she was taken to the operating room for a right colectomy. the procedure itself was relatively unremarkable. intraoperatively she did have a central line that was placed along with a swan ganz catheter, and the patient's do not resuscitate status was revoked for the 48 hours following surgery. patient's postoperative course was relatively unremarkable. on the first postoperative day her nasogastric tube was discontinued. by the second postoperative day we were able to discontinue both her swan ganz catheter and her arterial line. during this time she did resume do not resuscitate status after discussions with the family. a digoxin level was drawn revealing a level of 2.3 which is high, so her digoxin was held for one day followed by re-institution of therapy at a lower dose of 0.125 mg po q day. in addition, the patient did have some perioperative ekg changes including inverted t waves in leads v1 and v2. for this reason the patient was ruled out for myocardial infarction with serial enzymes. by the fourth postoperative day patient's bowel function was slow to return and she was initiated on total parenteral nutrition therapy. during her postoperative days she did require transfusion with one unit of packed red blood cells. by the fifth postoperative day the patient was able to start clear liquid and was advanced by that evening to soft solids. in addition, she did start to move her bowels. her bowel movements were noted to have melenic blood. however, patient had a large colonic operation involving re-anastomosis and the team was not concerned presently about the status of her bowel movements. by the 6th postoperative day the patient was taking a regular diet of soft solids in addition to boost supplements and her total parenteral nutrition was discontinued. plan was initiated to transfer the patient back to her nursing home. at time of dictation discussions are still pending with patient's primary care physician as to whether or not she is suitable to return to the level of care provided by her nursing home or if she instead requires a brief stay at the rehabilitation aspect of nursing home. discharge medications: aricept 5 mg po q day, ritalin 5 mg po q day, effexor xr 37.5 mg po q day, digoxin 0.125 mg po q day, lopressor 12.5 mg po bid, protonix 40 mg po q day. the patient does take a variety of other medications including multivitamins, other anti-hypertensive agents and lasix prior to this hospitalization. we are leaving it to the discretion of her primary care physician to reinstitute this therapy. she has demonstrated no signs of congestive heart failure and has not needed to be diuresed during her postoperative stay. however, as she resumes her normal activities and her regular diet, she may need further cardiac pharmacological intervention. on , the patient was transferred back to nursing home in , , for further management and care. discharge diagnosis: 1.
