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: the patient is a 79-year-old woman transferred from hospital with abdominal pain beginning a few days ago. the abdominal pain progressed to bloody diarrhea. of note, the patient had chronic atrial fibrillation secondary to bloody diarrhea and had stopped her coumadin on . a computed tomography scan at hospital suggested the diagnosis of a superior mesenteric artery embolus, and the patient also arrived with a white blood cell count of 44,000; but no fever or acidosis. the patient was transferred to the general surgery service and vascular surgery service for operative intervention. past medical history: 1. chronic atrial fibrillation. 2. hypertension. 3. hypothyroidism. medications on admission: (home medications included) 1. coumadin (last dose on ). 2. levoxyl. 3. potassium. 4. lasix. 5. premarin. allergies: allergy to codeine. physical examination on presentation: gentleman physical examination on admission revealed the patient was an elderly woman who was alert and with slurred speech. vital signs revealed temperature was 97.9, heart rate was 130 (in atrial fibrillation), blood pressure was 127/69, and oxygen saturation was 94% on room air. head, eyes, ears, nose, and throat examination revealed extraocular movements were intact. pupils were equal, round, and reactive to light. sclerae were anicteric. the throat was clear. edentulous. the neck was supple with no masses or lymphadenopathy. chest was clear to auscultation bilaterally. cardiovascular examination revealed irregularly irregular with no murmurs, rubs, or gallops. the abdomen was significant for positive bowel sounds. there is significant tenderness diffusely through the abdomen with no guarding. rectal examination was significant for guaiac-positive stool. extremities were warm, with no cyanosis, and no edema times four. neurologic examination was grossly intact; although it was difficult to assess with slurred speech. pertinent laboratory values on presentation: laboratories on admission with a complete blood count which revealed 44, hematocrit was 42, and platelets were 397. sodium was 136, potassium was 3.6, chloride was 93, bicarbonate was 25, blood urea nitrogen was 16, creatinine was 0.9, and blood glucose was 88. arterial blood gas revealed ph was 7.47, pco2 was 35, po2 was 75, bicarbonate was 26. pertinent radiology/imaging: abdominal computed tomography was significant for the suggestion of an occluded superior mesenteric artery, also a dilated small bowel, and no free fluid. hospital course: the patient was transferred for emergent management of probable superior mesenteric artery thrombosis or occlusion. the patient was taken to the operating room by the general surgery service and vascular surgery service. in the operating room, the patient had superior mesenteric artery thrombectomy with a vein patch angioplasty and significant small-bowel resection. please see the previously dictated operative reports for further details. in the postoperative period, the patient was managed in the intensive care unit. she was initially kept intubated and sedated and was given total parenteral nutrition for parenteral nutrition. she was closely monitored, and as she began to mobilize her fluids she was then actively diuresed and subsequently extubated without event. the patient remained on a heparin drip for appropriate anticoagulation. this was done in consultation with the neurology service. she was also maintained on ampicillin, ceftriaxone, flagyl for broad spectrum antibiotic coverage. her atrial fibrillation was controlled using a combination of metoprolol and diltiazem. the patient was noted to have some vaginal prolapse which was quite severe and eventually became nonreducible. the gynecology service was consulted and recommended simple followup as an outpatient. as the patient's clinical status improved and bowel function returned, her diet was advanced as tolerated. she was felt to be an aspiration risk, and a bedside swallowing study revealed no acute risk of aspiration; although, did not have in her false teeth at that time. eventually, the patient was transferred to the floor where she continued to do well. she did have multiple bowel movements per day and was clostridium difficile negative times four. ultimately, the patient was discharged on postoperative day 16. the patient was tolerating a regular diet with adequate pain control on oral pain medications. the patient was ambulating with assistance. the rest of this dictation will by issue/system: 1. neurologic issues: the patient came in with baseline slurred speech, and there was some concern for a cerebrovascular accident given her embolic event. the neurology service was consulted on postoperative day one, and a head computed tomography scan was obtained. the head computed tomography was consistent with a small subacute infarction in the right temporal lobe, left thalamus, and left insular cortex. no hemorrhage, or mass effect, and no shift. neurology assessment stated the patient was back to baseline; although, she did continue to have slurred speech throughout her hospital stay. the neurology consultation was obtained prior to surgery. postoperatively, the patient was maintained sedated in the intensive care unit until she could be weaned from her ventilator. after this, she had a few episodes of agitation which were controlled by ativan. otherwise, the patient was neurologically intact. 2. respiratory issues: postoperatively, the patient remained intubated. she initially had quite a bit of extra fluid volume on board, and the ventilator wean was very slow and prolonged due to this reason. it was felt that her airway was probably quite edematous, and that if the patient was extubated prematurely reintubation would be extraordinarily difficult. thus, extubation was only done after the patient had automatically diuresed a significant amount. after this, the patient really had no respiratory issues. she never had pneumonia or pneumothorax by multiple central line placements. 3. cardiovascular system: the patient remained in chronic atrial fibrillation throughout her stay. her heart rate was maintained using a combination of lopressor and diltiazem. she was never seen to be back in a normal sinus rhythm. an echocardiogram was obtained which did rule out clot. of note, the echocardiogram did show mild-to-moderate mitral regurgitation. for further details, please see the echocardiogram report of . the patient was maintained on a therapeutic heparin drip throughout her hospitalization until she was taking oral intake. at that time, she was begun on oral coumadin. the heparin was discontinued after the inr became 2 or greater. 4. gastrointestinal issues: the patient showed slow return of bowel function. she was begun on a clear liquid diet and advanced as tolerated. on at least one occasion she was seen to be choking on her clears, and a bedside swallow study was made. they could not definitively rule out the risk of aspiration and recommended ground foods with thin liquids. the patient seemed to do well this afterward; although, she did not take large amounts of oral intake. of note, the patient did have multiple liquid stools after her oral diet was restored. she tested negative for clostridium difficile times four. the patient was also begun on questran in an attempt to slow her bowel movements. this was done because a significant portion of the ileum was removed, and it was thought that the patient may not be absorbing her bile salts. 5. infectious disease issues: the patient was initially begun on broad spectrum triple antibiotic therapy with ampicillin, gentamicin, and flagyl postoperatively. her culture data was significant for methicillin-resistant staphylococcus aureus growing from a right internal jugular central line catheter tip on . the patient was given levofloxacin for this, as this particular variety of methicillin-resistant staphylococcus aureus was not resistant to levofloxacin. the patient had methicillin-resistant staphylococcus aureus screens performed on and from nares and rectal swabs which were negative. the patient completed a 10-day course of levaquin for the catheter tip culture and was seen to afebrile since then. 6. hematologic issues: the patient's initial clinical problem began with a probable embolic event the superior mesenteric artery. subsequent to her surgery, she was maintained on a therapeutic heparin drip at all times. she was eventually transitioned to coumadin when she began taking oral intake, and the heparin drip was stopped when this was therapeutic. otherwise, the patient was transfused appropriately around the time of surgery to maintain a hematocrit of 30 or greater. physical examination on discharge: in general, the patient was in no acute distress. vital signs were stable, afebrile. the chest was clear to auscultation bilaterally. cardiovascular examination revealed irregularly irregular. the abdomen soft, nontender, and nondistended with a midline incision which was steri-stripped. there was no erythema or exudate from the wound. the extremities were warm, no cyanosis, no edema times four. neurologic examination was grossly intact. discharge disposition: to a rehabilitation facility. condition at discharge: condition on discharge was good. discharge diet: diet is ad lib, supplemented with boost or equivalent t.i.d. the patient will need encouragement in oral intake. her oral intake will probably increase when she gets her teeth from her family. medications on discharge: 1. atenolol 100 mg p.o. q.d. 2. diltiazem 30 mg p.o. q.d. 3. questran 4 mg p.o. b.i.d. 4. levothyroxine. 5. coumadin (adjust for a goal inr of between 2 and 3). discharge instructions/followup: 1. the patient was to follow up with dr. in two weeks' time. 2. encourage oral intake and supplement diet with boost or equivalent t.i.d. 3. physical therapy is necessary for conditioning and gait training. 4. the patient does have multiple loose stools per day. a foley catheter is in place. the foley catheter may be discontinued at any time and have a voiding trial. 5. the patient may also need to follow up with an ob/gyn of her choosing for her vaginal prolapse. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified continuous invasive mechanical ventilation for 96 consecutive hours or more parenteral infusion of concentrated nutritional substances pulmonary artery wedge monitoring small-to-small intestinal anastomosis repair of blood vessel with tissue patch graft multiple segmental resection of small intestine excision of lesion or tissue of large intestine diagnoses: pneumonia, organism unspecified unspecified acquired hypothyroidism atrial fibrillation other shock without mention of trauma alkalosis infection and inflammatory reaction due to other vascular device, implant, and graft acute vascular insufficiency of intestine unspecified transient cerebral ischemia
