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: ms. is a -year-old female with a history of gastroesophageal reflux disease who presented to at 2 a.m. after two episodes of coffee-grounds emesis as her nursing home. on the night of admission, she vomited 500 cc of coffee-grounds and then subsequently had another episode of 500 cc of frank blood at 8:45 p.m. she said she had not been feeling well the entire day. in the emergency department, the patient had another 700-cc episode of bright red hematemesis. nasogastric lavage did not clear after one liter. she was originally admitted to the medical intensive care unit. an esophagogastroduodenoscopy showed a gastric ulceration with a large adherent blood clot on the posterior wall of the mid body of the stomach. the clot was removed revealing an underlying 1-cm cratered ulceration with a visible vessel. endoclips were applied to the ulceration base. helicobacter pylori serologies were sent. there was also evidence of a small hiatal hernia, duodenitis, and duodenal ulcerations. when seen in the medical intensive care unit, the patient had no complaints. she denied any chest pain, shortness of breath, abdominal pain, or lightheadedness. the patient also denied any history of nonsteroidal antiinflammatory drug use or significant alcohol history. she denied any previous bleeding episodes; however, she did report several days of black tarry stools prior to admission and said that overall she was not feeling well. the patient denied any fevers or chills. in the medical intensive care unit, she was transfused with 2 units of packed red blood cells and was hemodynamically stable. past medical history: 1. gastroesophageal reflux disease. 2. paroxysmal atrial fibrillation with a rapid ventricular rate. 3. rectal prolapse and hemorrhoid surgery in . 4. colonic polyps (benign). allergies: the patient has no known drug allergies. medications on admission: 1. colace. 2. aspirin 325 mg by mouth once per day. 3. multivitamin one tablet by mouth once per day. 4. zoloft 50 mg by mouth once per day. 5. digoxin 0.125 mg by mouth once per day. 6. ritalin. 7. os-cal. 8. aricept 5 mg by mouth once per day. 9. remeron by mouth at hour of sleep. social history: the patient is a nursing home resident. she lives at in . she reports occasionally smoking approximately five cigarettes per week. the patient reports occasional alcohol use. she denies any other drug use. family history: family history was noncontributory. physical examination on presentation: vital signs revealed her temperature was 98 degrees fahrenheit, her heart rate was 94, her blood pressure was 113/41, her respiratory rate was 18, and her oxygen saturation was 98% on room air. in general, she was an elderly female sitting comfortably in a chair. she was in no acute distress. head, eyes, ears, nose, and throat examination revealed the pupils were equal, round, and reactive to light. the extraocular muscles were intact. the neck was without appreciable jugular venous distention at 45 degrees. there was no lymphadenopathy. her heart was regular. there was a 2/6 systolic ejection murmur at the left lower sternal border as well as systolic. the lungs were clear to auscultation bilaterally. the abdomen was soft, nontender, and nondistended. she had decreased bowel sounds. the extremities were thin with good pulses. she had pneumatic boots in place. pertinent laboratory values on presentation: laboratories on admission with a complete blood count which revealed a white blood cell count of 15, her hematocrit was 30.7 in the medical intensive care unit after receiving 2 units of packed red blood cells, her hematocrit prior to transfusion was 25, and her platelets were 197. she had a prothrombin time of 12.7, her partial thromboplastin time was 22.6, and her inr was 1. her serum chemistries were all normal other than a blood urea nitrogen of 80. she had helicobacter pylori serologies sent at the time of the esophagogastroduodenoscopy. concise summary of hospital course by issue/system: 1. gastrointestinal issues: the patient was admitted with an upper gastrointestinal bleed with an esophagogastroduodenoscopy showing evidence of a gastric ulceration with stigmata of recent bleeding and underlying blood vessel that was clipped at the time of the esophagogastroduodenoscopy. the patient received 2 units of packed red blood cells in the medical intensive care unit. on the night after transfer to the floor, the patient's hematocrit fell from 30 to 27 and she received another unit. from that time forward, her hematocrit was stable. the patient was hemodynamically stable throughout her admission. the patient was placed on protonix 40 mg intravenously q.12h. which was subsequently changed to 40 mg by mouth q.12h. the patient's diet was advanced as tolerated. helicobacter pylori serologies done at the time of the esophagogastroduodenoscopy were positive on the day prior to discharge, and she was started on clarithromycin 500 mg by mouth twice per day, amoxicillin 1 gram by mouth q.12h., and was continued on her protonix 40 mg by mouth q.12h. the patient was to stay on the protonix for two months and clarithromycin and amoxicillin for two weeks. her aspirin will be held indefinitely. the patient was to have followup with the division of gastroenterology and will most likely require a repeat endoscopy in several months. 2. cardiovascular issues: per her granddaughter, the patient has a history of paroxysmal atrial fibrillation with rapid ventricular response. it was unclear at the time of admission why she was on digoxin; however, her granddaughter stated that she was placed on it when her atrial fibrillation was first noted. however, the patient has never been anticoagulated. the patient was continued on digoxin 0.125 mg by mouth every day and had no other cardiac events. 3. neurologic issues: the patient has an underlying history of dementia and is on aricept and ritalin as an outpatient. it was noted two days prior to discharge and on the day of discharge that her memory was somewhat worse with very low short-term memory. her daughters felt that this was most likely secondary to disorientation and confusion after being in the hospital and displaced from familiar surroundings. the patient was continued on her aricept, ritalin, and remeron. discharge diagnoses: 1. upper gastrointestinal bleed. 2. dementia. 3. helicobacter pylori infection. 4. gastric ulceration. medications on discharge: 1. protonix 40 mg by mouth q.12h. (times two months). 2. clarithromycin 500 mg by mouth twice per day (times 14 days). 3. amoxicillin 1 gram by mouth q.12h. (times 14 days). 4. digoxin 0.125 mg by mouth once per day. 5. multivitamin one tablet by mouth once per day. 6. ritalin 5 mg by mouth twice per day. 7. remeron 15 mg by mouth at hour of sleep. 8. zoloft 50 mg by mouth once per day. 9. aricept 5 mg by mouth at hour of sleep. condition at discharge: at the time of discharge, the patient was confused but redirectable. she was repeatedly asking why she was here and clarifying where she was. she was without other physical complaints. her vital signs were stable. her hematocrit was stable at approximately 30. discharge status: the patient was to be discharged back to nursing home and was to be scheduled for gastrointestinal followup and will need follow up with her primary care physician in the next week. , m.d. dictated by: medquist36 procedure: endoscopic control of gastric or duodenal bleeding endoscopic control of gastric or duodenal bleeding transfusion of packed cells diagnoses: acute posthemorrhagic anemia atrial fibrillation diaphragmatic hernia without mention of obstruction or gangrene chronic or unspecified gastric ulcer with hemorrhage, without mention of obstruction helicobacter pylori [h. pylori] 

Answer: The patient is high likely exposed to
