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 major surgical or invasive procedure: colonscopy history of present illness: 86yo m with h/o gastric ulcers admitted with brbpr. pt with hx of gastric ulcers here with rectal bleeding starting today. had 6 total episodes today. no chest pain, sob, lightheadedness, dizziness. in the ed, initial vs were: t98.2 hr75 bp:129/70 rr:16 o2sat:100ra. gross blood on rectal exam. underwent ng lavage which came back bilious with no blood or clots. was going to be admitted to the floor, however, when he got up to use the bedside commode he had a large (1l) bloody bm. he then got up off the commode, felt weak and syncopized onto the bed(did not hit his head) and was transiently not breathing and pulseless. responded within seconds and was then a&ox3. gi team saw him afterward in ed but did not feel comfortable sending patient for tagged rbc scan in setting of slightly unstable vital signs. patient received 2 units uncrossmatched prbcs in ed and another 2units crossed matched cells on arrival to micu. general surgery was consulted. vs prior to transfer to micu: bp 87/65 hr 65 o2sat100% nrb. on the floor, patient is feeling comfortable. no abdominal or chest pain. review of systems: (+) per hpi (-) denies fever, chills, night sweats, recent weight loss or gain. denies cough or wheezing. denies chest pain, chest pressure, palpitations, or weakness. denies nausea, vomiting, constipation, abdominal pain. past medical history: cki (baseline creatinines over last year 1.1-1.3) gastric ulcers s/p billroth procedure gerd hypothyroidism celiac disease social history: the patient has never smoked tobacco. he does not drink any alcohol. he has never done any drugs. he is sexually active with his wife. originally from , usually lives with his wife, but his wife is back in right now for another couple of weeks. his nephew was shot in the abdomen in , so his wife went back to to be with him. patient denies any history of smoking. he currently has a couple of jobs, including selling spanish newspaper on the street. lives . in , he used to be a politician. moved here about 10 years ago. family history: his mother had lung cancer. his brother had leukemia, and another brother had disease. physical exam: vitals: bp:128/75 p:75 r: 18 o2: 100 general: alert, oriented, no acute distress heent: sclera anicteric, dry mm, oropharynx clear neck: supple, jvp not elevated, no lad lungs: clear to auscultation bilaterally, no wheezes, rales, ronchi cv: regular rate and rhythm, normal s1 + s2, no murmurs, rubs, gallops abdomen: soft, non-tender, non-distended, bowel sounds present, no rebound tenderness or guarding, no organomegaly gu: no foley ext: warm, well perfused, 2+ pulses, no clubbing, cyanosis or edema pertinent results: 08:23pm hct-35.8* 06:25pm ck(cpk)-83 06:25pm ck-mb-notdone ctropnt-<0.01 06:25pm hct-39.8* 02:11pm potassium-5.3* 02:11pm ck(cpk)-82 02:11pm ck-mb-notdone ctropnt-<0.01 02:11pm wbc-10.0 rbc-4.69 hgb-12.9* hct-39.2* mcv-84 mch-27.5 mchc-32.9 rdw-16.0* 02:11pm plt count-221 11:50am hgb-12.7* calchct-38 10:15am glucose-158* urea n-28* creat-1.3* sodium-141 potassium-5.5* chloride-102 total co2-30 anion gap-15 10:15am wbc-9.6 rbc-4.51* hgb-12.5* hct-37.9* mcv-84 mch-27.7 mchc-33.0 rdw-15.9* 10:15am neuts-69.8 lymphs-19.5 monos-5.1 eos-4.8* basos-0.6 10:15am plt count-282 10:15am pt-11.2 ptt-26.0 inr(pt)-0.9 ekg: new lbbb from prior on and also new from ed ekg. colonoscopy: polyps and diverticulosis. will need repeat colonoscopy in the future to remove polyps. no intervention. brief hospital course: mr. is an 86 y.o. spanish speaking male with history of pud s/p billroth ii and celiac disease, admitted on to micu for brbpr, s/p colonoscopy revealing diverticulosis. # lower gi bleed: patient had a h/o gastric ulcers so initially it was thought that he could have a very brisk ugib, but with negative ng lavage and rectal blood on exam, lower gi bleed felt more probable. he received 4 units prbcs, was prepped overnight and then underwent colonoscopy which revealed diverticulosis and several polyps but no active bleeding. the polyps were not removed given recent bleed and the patient will need another colonoscopy for removal as an outpatient. hcts remained stable and he was called out to the floor for observation. he passed two more clots of old blood per rectum while on the floor, then had no further bleeding for more than 24 hours. patient was discharged home but told to return if he had any further bleeding or if he developed lightheadedness. he was told to schedule a followup appointment with his pcp for as soon as possible on monday morning. because of his history of pud, he was re-started on omeprazole 20mg daily; he states he does not have any gastritis or reflux symptoms but will discuss whether or not this medication is needed with his pcp. # hyperkalemia: patient has had this in the past in the setting of arf; on admission, his creatinine was slightly elevated which likely contributed to hyperkalemia. there were no associated ekg changes and the k trended down through the course of his icu stay. # acute renal failure: his baseline creatinine 1.1-1.3 over the last 2 years and on admission his creatinine was high-normal for him at 1.3. this was thought likely pre-renal azotemia. his medications were renally dosed and the creatinine trended down during the course of his icu stay after transfusion. # left bundle branch block: patient did not have a history of lbbb including on an ekg 5 months prior to admission. as he had a syncopal event in the ed, which was thought likely vasovagal in setting of brbpr, cardiac enzymes were cycled to rule out cardiac event. enzymes remained negative. ekg remained unchanged although on telemetry patient noted to have intermittent lbbb. it was thought likely this lbbb was related to age-related degeneration of the cardiac conduction system and less likely acs so no further workup was pursued. repeat ekg showed persistent lbbb, not rate related. patient would benefit from echocardiogram as an outpatient. # communication: patient and wife , currently in ): # code: full (discussed with patient) medications on admission: none discharge medications: 1. 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* discharge disposition: home discharge diagnosis: 1. diverticular bleed discharge condition: mental status: clear and coherent. level of consciousness: alert and interactive. activity status: ambulatory - independent. discharge instructions: dear mr. , you were admitted with bleeding in your gi tract. we performed a cat scan of your abdomen and a colonoscopy, and found that you have a condition called "diverticulosis". your bleeding stopped on its own, and you now have a condition called "anemia" (low blood counts from bleeding), which will impove with time as your body recovers. you should eat a high fiber diet (at least 25-30g per day) to avoid further progression of divertiulosis. high fiber can be found in whole wheat products, fruits and vegetables. we also discovered that your blood sugar levels are slightly elevated, which indicates that you may have a condition called "diabetes". it is very important that you see dr. for follow up to have this treated. no changes have been made to your medications, but it appears that you have previously been prescribed omeprazole for reflux, which you may continue to take if you would like. we will give you a prescription which you may fill. please follow up with your pcp . within 2 weeks to have your blood counts monitored. we have also made you an appointment to see dr. in gastroenterology (see below) , ud fue hospital porque estaba colon. nos parace de tiene diverticulosis colon. le observabamos, y ahora no . ahora tiene anemia, dice el nivel de sus baja, va a mejorar en unas meses. debe ud comer una dieta con mucha fibra prevenir empeoramiento de diverticulosis. se puede encontrar fibra en vegetales y comida de . el nivel de azucar en sangre estaba este hospitalizacion, y es posible tenga diabetes. hay seguir con doctor . no hemos cambiado sus medicamentos, nos parece estaba tomando omeprazole en el pasado acidez, y puede ud continuar medicine si quiere. vamos a darle una receta . por favor, una cita con doctor 2 semanas chequear hematocrito ( ) y mantenga hemos hecho con el doctor (dr. . mucho gusto, y suerte con todo! followup instructions: provider: , .d. phone: date/time: 1:15 please call dr. at and make an appointment within 1-2 weeks procedure: colonoscopy diagnoses: hyperpotassemia diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled acute kidney failure, unspecified unspecified acquired hypothyroidism chronic kidney disease, unspecified other left bundle branch block celiac disease diverticulosis of colon with hemorrhage 

Answer: The patient is high likely exposed to
