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: iodine; iodine containing / levofloxacin / tetracycline / clindamycin attending: chief complaint: lower gi bleed acute blood loss anemia major surgical or invasive procedure: tagged rbc scan history of present illness: 78 yo man with h/o diverticulosis, ischemic small bowel with associated gi bleed s/p resection, hemmorhagic cva, distant etoh abuse, who presented to osh with brbpr, found to have diverticular gi bleed, and was transferred to for further management. the patient states that he awoke on and passed a large amount of blood in the toilet with his am bowel movement. he told his rn at the nh, who arranged for transfer to . there, he was noted to have an initial hct 43, inr 2.9. his hct dropped from 43->37->34 over his first night in the hospital. he went for a cspy that showed the area of most intense bleeding to be in the sigmoid and descending colon, with only backwash blood in the transverse colon. no polyps or avms were noted. he then had a tagged rbc scan which was positive at the splenic flexture. he continued to put out melanotic stool and his hct dropped from 34->28 over next 24h. he was then transferred to osh icu, given vit k 10mg, 1 unit prbc, 2 units ffp. . after discussion with surgery, the icu team decided to transfer the patient for angiography and embolization of the bleeding artery in his l colon. past medical history: pmh: -htn -cva, hemorrhagic; ; initially had l paresis which resolved, but continues to have residual memory deficit and ataxia -etoh, in the past -gerd -psoriasis -bph, with subsequent urinary retention and prior utis -colonic diverticuli, with several episodes of diverticulitis -ischemic small bowel assoc with gi bleed, s/p resection in -rheumatic heart disease, with cardiac murmur -first degree av block -vitamin b12 deficiency . psh: -partial small bowel resection for ischemia/bleed, done in social history: lives at house (nh), where he moved in after his stroke left him ataxic. he was married but is now a widower. he has 3 sons and 3 daughters, and his daughter/hcp is a rn at . tob: ppd x 40-50y (~120 pack-years). etoh: drank "a lot" of whisky when younger, then stopped when he had his stroke in . denies other drug use. . comm: primary contact is (daughter, hcp) (h), (c), (w);

held asa and bb initially, restarted bb in house, will defer restarting asa until outpt and stools are clear. b)rhythm: nsr c)pump: no evid of chf; has h/o rheum heart disease and murmur, though could not appreciate the murmur on our exam; held antihypertensives initially in case he opened up, then restarted once he stabilized. . gerd: cont ppi . bph: cont proscar, flomax . etoh history: cont thiamine, folate . b12 def: not on b12 currently per med list; checked level, found to be high normal; unclear if he has been getting this as outpt once per month and it was just not listed on his med list. will need to clarify with pcp and restart if indicated. . act: bedrest initially, then once he was stable was walked with a walker and remained stable on his feet . fen: npo initially, then advanced to regular cardiac diet which he tolerated well . ppx: ppi, pneumoboots, restarted bowel regimen as no bms x several days, fall precautions given ataxia . access: two large pivs . comm: primary contact is (daughter, hcp) (h), (c), (w);
