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: brbpr with need for urgent egd major surgical or invasive procedure: egd history of present illness: 83 yom with history of afib on coumadin, diverticulosis with prior lgib, presenting with brbpr. patient is deaf and some communication barriers at baseline due to difficulty with traditional asl. per best interpretation, he has had at least 2 weeks of diarrhea with dark/black stools. at times he has also seen a small amount of red blood/pink in the toilet. he saw his primary np and was found to have brb on rectal exam. hct over the last week dropped from 27 to 22. past medical history: - atrial fibrillation - hypertension - deaf/mute - gallstone pancreatitis - cholecystitis s/p cholecystectomy in - frequent falls social history: lives in senior citizen housing nearby in . independent with adls. brother and other family members nearby and available. no tobacco or etoh. family history: not elicited physical exam: exam at admission: general: alert elderly male, no distress, nontoxic appearing. heent: r eye round and reactive, l eye absent (congenital), full eoms. mm moist, edentulous, op clear. neck: thin, jvd to 5 cm asa. no adenopathy. chest: clear except few bibasilar crackles, r>l heart: irreg irreg, 2-3/6 sm at llsb. abdomen: soft, nd, no hsm or mass, very mild ttp in llq near iliac crest. extrem: slightly cool, bilateral venous stasis changes with 2+ edema to mid thigh.+ scrotal edema. neuro: alert, appears oriented x 3 though difficulty communicating exact answers to orientation questions pertinent results: labs at admission: 08:30pm pt-38.0* ptt-32.4 inr(pt)-3.9* 08:30pm plt count-271# 08:30pm wbc-7.3 rbc-2.38*# hgb-6.4*# hct-21.0*# mcv-88 mch-26.8*# mchc-30.3*# rdw-14.2 neuts-72.2* lymphs-22.0 monos-3.1 eos-1.9 basos-0.7 08:30pm tsh-3.5 08:30pm caltibc-294 vit b12-193* folate-15.8 ferritin-35 trf-226 08:30pm albumin-3.6 iron-15* 08:30pm ck-mb-7 ctropnt-0.04* 08:30pm alt(sgpt)-10 ast(sgot)-20 ld(ldh)-199 ck(cpk)-156 alk phos-52 tot bili-0.3 11:00pm urine blood-neg nitrite-neg protein-neg glucose-neg ketone-neg bilirubin-neg urobilngn-neg ph-5.0 leuk-sm rbc-0-2 wbc- bacteria-none yeast-none epi-0-2 imaging: echo the left atrium and right atrium are normal in cavity size. there is mild symmetric left ventricular hypertrophy with normal cavity size and regional/global systolic function (lvef>55%). right ventricular chamber size and free wall motion are normal. the aortic valve leaflets (3) are mildly thickened but aortic stenosis is not present. no aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. there is no mitral valve prolapse. mild (1+) mitral regurgitation is seen. the tricuspid valve leaflets are mildly thickened. there is moderate pulmonary artery systolic hypertension. there is no pericardial effusion. egd no fresh or old blood was found. otherwise normal egd to third part of the duodenum. colonoscopy : diverticulosis of the whole colon polyps in the distal transverse colon and rectum (polypectomy) polyp in the proximal ascending colon ulceration, erythema and granularity in the proximal ascending colon compatible with indetermined colitis (biopsy) otherwise normal colonoscopy to cecum and terminal ileum brief hospital course: 83yo deaf male with atrial fibrillation presenting with lower gib in the setting of supratherapeutic inr on coumadin, admitted to the icu s/p 3 units of prbcs with normal transferred to floor with colonoscopy significant for diverticulosis, two colonic polyps, and non-specific colitis of proximal colon. . # brbpr: pt reports several days of brbpr. in the ed the patient received 2 units of prbc's and 2 units of ffp for concern of gi bleed and anti-coagulation was reversed with vitamin k for supratherapeutic inr of 3.9. patient's hematorcrit and coagulation labs responded appropriately to the interventions. patient underwent urgent egd to evaluate for ugib source, no source was found. serial hct were followed and continued to trend downward over the next 24 hours. patient was transfused 1 unit prbc's for drop to 24.5 on hd2. colonoscopy was performed after patient was transferred to the floor, and showed extensive diverticulosis (no source of bleed), two small polyps, one in ascending colon and one in transverse colon (which were excised and specimen sent to pathology), localized inflammation in the proximal ascending colon, most suspicious for the source of pt's gib (biopsy was sent to r/o lymphoma). pt had no further episodes of brbpr and hct was stable on the floor. . # anemia: patient initially presented with 5 pt drop in hematocrit over 1 week in setting of gib. pt also found to be b12 and iron deficient. b12 repletion was continued. gi recommended holding iron supplementation due to concern for false guiac positivity, but this should be re-addressed as an outpatient. . # sob: pt reported sob over several days up to admission. felt to be multifactorial. likely contributing factors include anemia (prior to admission). on admission pt recieved blood and then became fluid overloaded requiring lasix. further, gi reported patient may have aspirated peri-procedure during egd. repeat cxr showed worsening rll airspace disease concerning for aspiration although time course of event remained unclear. was febrile to 101f on , so he was pan-cultured and started on unasyn. cultures were negative and pt completed a 5 day course of unasyn with low suspicion for pneumonia, more likely diagnosis aspiration pneumonitis. . # atrial fibrillation: initially patient's anticoagulation and rate control medications were held in setting of gib. diltiazem was restarted for afib, though lopressor continues to be held upon transfer from micu. lopressor and diltiazem were restarted at home doses on the floor. coumadin was discontinued as pt's chads2 score is 2 and given history of repeat gib, and pt was started in aspirin 325mg daily prior to discharge. . # anasarca: patient initially presented with bilateral lower extremity edema with visible jvp. cxr was also notable for pulmonary edema. patient with left parasternal systolic murmur on exam. on patient underwent tte to evaluate cardiac function which showed no change from previous (normal lvef > 55 % and mild 1+ mr). . # heart murmur: left parasternal systolic murmur evaluated with tte which showed normal lvef > 55 % and mild 1+ mr. s were trended and unremarkable. medications on admission: diltiazem 120 mg daily metoprolol xl 200 mg daily omeprazole 20 mg daily coumadin 5mg daily discharge medications: 1. metoprolol succinate 200 mg tablet sustained release 24 hr sig: one (1) tablet sustained release 24 hr po daily (daily). disp:*30 tablet sustained release 24 hr(s)* refills:*2* 2. cyanocobalamin 500 mcg tablet sig: two (2) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 3. diltiazem hcl 120 mg tablet sustained release 24 hr sig: one (1) tablet sustained release 24 hr po once a day. disp:*30 tablet sustained release 24 hr(s)* refills:*2* 4. omeprazole 20 mg capsule, delayed release(e.c.) sig: one (1) capsule, delayed release(e.c.) po once a day. disp:*30 capsule, delayed release(e.c.)(s)* refills:*2* 5. aspirin 325 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* discharge disposition: home with service facility: homecare discharge diagnosis: lower gastrointestinal bleed -colonic polyps, biopsied -colitis of the right proximal colon, biopsied -diverticulosis . secondary diagnosis: atrial fibrillation hypertension discharge condition: medically stable. discharge instructions: you presented to the hospital with bloody bowel movements which required blood transfusions in the intensive care unit. you underwent an endoscopy which was normal, and a colonoscopy which showed inflammation of a part of your colon, two polyps in your colon, and diverticulosis. biopsies were sent of your colon and the polyps, and you will follow up the results of this with your gastroenterologist at your next appointment. . while in the hospital, you were also treated with antibiotics for a possible pneumonia. the antibiotics were completed before you were discharged from the hospital, and you will not be taking any antibiotics at home. . the following medication changes were made: - coumadin was discontinued. - aspirin 325mg daily was started. - vitamin b12 was started. . if you develop fevers, dizziness, shortness of breath, productive cough, pain on urination, significantly increased urinary frequency, or recurrence of bloody bowel movements, please return to the hospital. followup instructions: please see dr.
