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: past medical history: 1. prostate ca, status post xrt. 2. hypertension. 3. gerd. 4. emphysema. 5. uri. allergies: the patient has no known drug allergies. medications on admission: 1. lisinopril. 2. senna. 3. zantac. 4. tylenol. past surgical history: 1. status post appendectomy. 2. status post left knee surgery. 3. status post colostomy. physical examination on admission: the patient was pleasant and cooperative, in no acute distress. the heart revealed a regular rate and rhythm. the lungs were clear to auscultation bilaterally. the abdomen was soft, nontender, nondistended. the extremities were warm and perfuse. no edema. hospital course: the patient was taken to the operating room on where exploratory laparotomy was performed. the patient had multiple metastases so gastrectomy was not performed. the patient had two omental biopsies, liver biopsy, and was transferred to the pacu in stable condition and later to the floor. however, on the floor, the patient's respiratory status had decreased. he required increasing amounts of oxygen until finally he became unresponsive and hypotensive. he was intubated. iv fluids were started and he was transferred to the sicu. he required levo for hypotension. chest x-ray showed a right infiltrate. he was also started on lasix for pulmonary edema. the patient did not require levo by postoperative day number two. attempts to extubate the patient on postoperative day number two and three failed. we were not able to wean him off the ventilator. he was extubated on postoperative day number four. over the next few days he continued to have shortness of breath. he developed tachycardia up to 120-130. his blood pressure remained stable. he was producing large amounts of mucus. his chest x-ray was unremarkable except for a suspicious opacification in the left lobe which was considered to be a possible pneumonia. the patient was started on levo. he was also started on lopressor and then diltiazem drip for tachycardia control. on postoperative day number six, the patient was started on a combination of oral and iv lopresor which seemed to control his tachycardia much better. there was a suspicion of aspiration so a video swallow study was performed which showed the patient aspirates some air when using a straw, however, can drink normally from a cup without any aspiration. the patient's respiratory status has improved. he was started on chest pt which produced a large amount of mucus. his shortness of breath has improved. his heart rate and blood pressure were under control. he was transferred to the floor on postoperative day number seven. on postoperative day number eight and nine, the patient continued pt and chest pt with improving strength. his respiratory status is improving. he has a little bit less shortness of breath; however, he still requires 02. he was progressed to a general diet which he was tolerating well. he was passing gas and stool. on postoperative day number nine, the patient was afebrile. the vital signs were stable to 96-97% 02 saturation on 2 liters, producing large amounts of clear sputum (cultures were negative to date on the oropharyngeal flora). the patient was ambulating with help. no concerns. no active issues at this time. condition on discharge: stable. disposition: the patient was discharged to rehabilitation. the patient should continue his pt to a goal of independent ambulation, chest pt with a goal of weaning off 02. regular diet as tolerated. the patient should not drink through a straw. follow-up: the patient should contact dr. for a follow-up appointment. the staples will be removed at follow-up. medications on discharge: 1. sarna lotion applied to affected area p.o. q.i.d. p.r.n. 2. albuterol inhaler q. 4-6 hours p.r.n. 3. ipratropium inhaler q. six hours p.r.n. 4. beclomethasone inhaler two puffs q.i.d. 5. lisinopril 20 mg q.d. 6. percocet one to two tablets p.o. q. 4-6 hours p.r.n. 7. lopressor 25 mg t.i.d. 8. tamsulosin 0.4 mg q.d. 9. protonix 40 mg q.d. diagnosis on discharge: 1. gastric ca. 2. prostatic ca, status post exploratory laparotomy, omental biopsy, liver biopsy. 3. hypertension. 4. respiratory distress. 5. pulmonary edema. 6. hypertension. 7. hypovolemia. 8. gastroesophageal reflux disease. 9. emphysema. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours insertion of endotracheal tube excision or destruction of peritoneal tissue repair of other hernia of anterior abdominal wall partial hepatectomy excision of lesion or tissue of diaphragm diagnoses: malignant neoplasm of liver, secondary cardiac complications, not elsewhere classified pneumonitis due to inhalation of food or vomitus other emphysema secondary malignant neoplasm of retroperitoneum and peritoneum ventral, unspecified, hernia without mention of obstruction or gangrene malignant neoplasm of other specified sites of pancreas 

Answer: The patient is high likely exposed to
