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: this is a 79-year-old male with a history of diverticulosis, hypertension, thalassemia and prostate cancer who presents with bright red blood per rectum starting at approximately 4:30 am on the day of admission. he was up at 4 am, had some water, then had a loose yellow bowel movement with no blood. about one-half hour later he had bright red blood per rectum then came immediately to the emergency room where he reports three more episodes of bright red blood per rectum. usually the patient has one brown bowel movement per day, no melena or bright red blood per rectum usually. he ate four handfuls of popcorn last night and watermelon with seeds. he denies chest pain, shortness of breath, abdominal pain, nausea, vomiting, or diarrhea. he was dizzy only when an nasogastric tube was attempted to be placed. in the emergency room the patient received fluids and protonix and had a stable blood pressure. gastrointestinal saw the patient and recommended a colonoscopy but not urgently. no nasogastric lavage was done as the tube could not be passed. past medical history: hypertension, thalassemia, prostate cancer not being treated, history of a diverticular bleed ten years ago. he reports having a normal colonoscopy here at that time though it is not in our computer system. the patient states he has a history of a heart murmur, history of gout. allergies: the patient has no known drug allergies. medications: atenolol 50 mg p.o. q.d.;

no wheezes, no rales. abdomen was soft, nontender, and nondistended, positive bowel sounds. genitourinary examination showed bright red blood per rectum per the emergency room. extremities had no edema. neurological examination showed cranial nerves two through 12 were intact. strength was throughout. he had an ekg that was normal sinus rhythm at 67, left axis deviation with normal intervals, no st elevation or t wave inversion. he did have mild upsloping of the t wave in v2 through v4 which could be called j point elevation. there is no old film to compare. laboratory studies: his admission hematocrit was 36.7. discharge hematocrit was 30.4. white count 10.7, mcv 67, 58.2 neutrophils, 35.8 lymphocytes, 3.0 monocytes, 2.3 eosinophils, 0.6 basophils. platelet count was 133. pt 12.8, ptt 28.3, inr 1.1. glucose 131, bun 9, creatinine 0.8, sodium 138, k 5.1, hemolyzed, chloride 105, bicarbonate 22, alt 16, ast 41, amylase 45. cks x 3 were 59, 30 and 36. lipase was 34, troponin less than 0.3 x 3. calcium 8.9, phosphorous 4.4, magnesium 1.9, iron 84, tibc 324, ferritin 364, trf 249, hemoglobin a1c 6.1. hospital course: this was a very pleasant 79-year-old man with a lower gastrointestinal bleed. 1. gastrointestinal: the patient received a total of four units of packed red blood cells with only one more episode of bright red blood when he reached the intensive care unit. the patient had a colonoscopy which showed multiple diverticula and internal hemorrhoids. the patient did receive p.o. protonix during his course here, though he was not discharged on that. the patient was discharged and advised to avoid seeds, nuts and popcorn. 2. hypertension: the patient had a history of hypertension. his medications were held here and he was advised to restart them as an outpatient on the day after discharge. 3. thalassemia: stable with his low mcv. 4. endocrine: the patient had an elevated blood glucose when he arrived. we did q.i.d. fingersticks x 1 day and hemoglobin a1c was sent. on further information the patient said he has had some glucose intolerance in the past and actually sees a doctor . 5. cardiovascular: the patient had a murmur that he states was worked up in the past with echocardiogram. he stated he has not had a recent stress test. due to the j point elevation and repeat ekg showing some t wave flattening, would recommend and outpatient stress and an outpatient echocardiogram to work-up the patient's murmur. disposition: the patient was discharged to home in stable condition. he was given the phone number for dr. and associates to follow up for his primary care physician. discharge medications: he was to return to his regular outpatient regimen of atenolol, accupril and allopurinol. the patient was to follow up with his new primary care physician in two weeks. , m.d. dictated by: medquist36 procedure: colonoscopy diagnoses: unspecified essential hypertension malignant neoplasm of prostate diverticulosis of colon with hemorrhage internal hemorrhoids without mention of complication 

Answer: The patient is high likely exposed to
