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: bloody bowel movements major surgical or invasive procedure: flexible sigmoidoscopy on history of present illness: mrs. is a very nice 88 year-old woman with a severe dementia, diverticolosis, pud, chronic anemia who comes with after having multiple bowel movements with clots. she was in her prior state of health until ~1 week ago when at the facility that she lives (newbridge on at deedham). she was seen by her vna who performed a rectal exam 4 days ago and found her to have guaiac positive stools which may have been a false positive due to iron supplementation. on the morning of admission, she started passing blood clots with her bowel movments so she was sent to the er. she denies any palpitations, chest pain, diziness, lightheadedness, epigastric pain, abdominal pain, orthopnea, shortness of breath. there has not been any bright red blood per rectum. ambulance was called and when ems arrived her vs were t97.4 hr:60 bp:146/67 resp:18 o2sat:100 normal. in the er her initial vs were t 97.4 f, bp 146/67 mmhg, hr 60 bpm, rr 18 x', spo2 100% on ra with pain 0/10. her bp was table thoughout the ed stay with sbp ranging from 120-150 with hr in 60s (on metoprolol). pt had no abdominal pain and was guaiac positive. she had multiple bowel movements with dark maroon-colored stools. her cxr showed opacity in the lll that could be compatible with atelectases or pna, so patient received ceftriaxone/azithromycin. she was t&s and received 2 rbc units. she had an 18-g placed in the antecubital fosa, but dr. expressed patient had "2 large ivs". ecg showed sinus bradycardia without signs of ishcemia. past medical history: diverticulosis - patient was scoped 3-4 years ago for anemia. peptic ulcer disease - patient with egd showing pud 3-4 years ago. alzheimer's dementia - a&o x1. breast cancer s/p right mastectomy & radiation anemia - chronic on iron replacement therapy htn hypercholesterolemia urinary incontinence depression -

grade 1 internal hemorrhoids - diverticulosis of the sigmoid colon and descending colon - polyp at 70cm in the splenic flexure (polypectomy) - otherwise normal sigmoidoscopy to proximal transverse colon brief hospital course: 88 year-old woman presents with maroon-colored stool with blood clots. tagged rbc scan showed that the bleed was from a sigmoid vessel. the patient was transfused 6 units of prbc (last unit on ). she was initially observed to have maroon colored stool. hct remained stable after last transfusion on . angiography was performed to try to intervene on the bleeding vessel after it was identified on the tagged rbc scan, but no further bleeding was found. flexible sigmoidoscopy on found no active bleed, but did find grade 1 internal hemorrhoids and diverticular disease. the patient was continued with iron supplementation throughout the hospital admission and was witnessed to have black (non-foul-smelling) stool on the day of discharge (but no blood clots and no further maroon-colored stool). with the known gi bleed being in the sigmoid colon and the hematocrit being stable, the black stool is attributed to iron supplementation rather than upper gi bleed. problem list: # anemia: patient with normocytic, normochromic anemia with normal rdw, who has history of pud and diverticulosis and prior diagnosis of iron deficiency anemia on iron replacement therapy. iron deficiency was likely prior bleeding. iron studies this admission were normal. iron was discontinued at discharge given normal iron levels. # alzheimer dementia: baseline is a&o x name only. continue donepezil. # hypertension: beta blocker intially held. metoprolol restarted as metoprolol 25mg po bid in place of the long acting form. transitioned to long-acting toprol xl at discharge. # hypercholesterolemia: statin continued. # h/o breast cancer: in remision. no bp or blood draws in r arm. # code status -
