In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

[EX Q]: Context: To test device integrity and objective auditory reaction for cochlear implant patients intraoperatively.', 'Our protocol for intraoperative testing of the implant device includes device electrode impedance test and neural response telemetry (NRT), which measures the electrically evoked auditory nerve compound action potentials (ECAP).', 'We completed electrode integrity tests and NRT intraoperatively on 40 patients with the Nucleus CI24M cochlear implant. We have measured normal implant function on all 40 patients and obtained ECAP results from 39 patients. Out of 33 patients with normal inner ear, typical ECAPs were recorded in 195 electrodes in all 198 testing electrodes(98.5%). In 7 patients with inner ear Mondini dysphasia, affirmative ECAP waveforms were recorded in 26 electrodes in all 42 testing electrodes. The basal electrode ECAP threshold was higher than that of the epical one.\Question: Do [ The intraoperative application of neural response telemetry with the nucleus CI24M cochlear implant ]?
[EX A]: The intraoperative measurements of device function and NRT are quite simple, quick and with high accuracy. Inner ear malformation is an important factor that may affect NRT results.

[EX Q]: Context: Accumulating evidence has indicated that inflammation may act as a potential mechanism underlying post-operative cognitive dysfunction (POCD). High-mobility group box 1 (HMGB1), as a known late mediator of inflammation, is involved in the development of post-operative complications. Thus, we sought to determine the role of HMGB1 in reflecting POCD following major gastrointestinal surgery.', 'Fifty-three elderly patients undergoing gastrointestinal surgery were recruited, and 50 patients completed the study. Serum HMGB1 and interleukin (IL)-6 levels were measured pre-operatively and at 6 h, day 1 and day 3 post-operatively. Neuropsychological tests were administered before and 1 week after surgery. POCD was determined using a Z score 1.96.', 'Seventeen (34%, 17/50) patients developed POCD at 1 week. The POCD group had higher serum HMGB1 levels at day 1 (12.15 3.12 vs. 9.91 3.15 ng/ml, P = 0.021) and day 3 (11.04 2.88 vs. 8.52 3.31 ng/ml, P = 0.011). IL-6 levels at 6 h (51.18 15.22 vs. 39.20 14.32 pg/ml, P = 0.009) and day 1 (41.59 11.08 vs. 33.81 11.42 pg/ml, P = 0.026) were significantly higher in POCD patients. Serum values of IL-6 at 6 h, HMGB1 at day 1 and levels of education showed positive correlations with Z scores. HMGB1 at day 3 and IL-6 at 6 h were independent risk factors.\Question: Does serum high-mobility group box 1 protein correlate with cognitive decline after gastrointestinal surgery?
[EX A]: Serum HMGB1 and IL-6 levels increase significantly after major gastrointestinal surgery in elderly patients and such elevations are associated with the occurrence of cognitive decline after surgery.

[EX Q]: Context: Analysis of coronary flow velocity (CFV) in the recanalized infarct-related coronary artery (IRA) with a Doppler guidewire is useful for predicting recovery of regional left ventricular function, in-hospital complications, and survival. We postulated that the CFV pattern after IRA reperfusion for acute myocardial infarction (AMI) would predict long-term adverse cardiac events.', 'Sixty-eight consecutive patients with a first AMI underwent CFV measurement with a Doppler guidewire after successful reopening of the IRA by coronary angioplasty. At the end of follow-up, 3.8+/-1.7 years after AMI, 44 of the 65 surviving patients (67.7%) were free of long-term cardiac events. Univariate analysis showed that the following factors were predictive of an end point combining cardiac death, recurrent MI, and congestive heart failure: hypertension, age > or =65 years, time from onset of chest pain to PTCA > or =6 hours, peak creatine kinase >4000 IU/L, ejection fraction < or =50%, proximal left anterior descending artery occlusion, resting average peak velocity < or =10 cm/s, average systolic peak velocity < or =5 cm/s, a rapid diastolic deceleration time (< or =600 ms), and early retrograde systolic flow. In the final multivariate model, only age > or =65 years (OR, 3.6; 95% CI, 1.1 to 11.8; P=0.03), time to PTCA > or =6 hours (OR, 2.9; 95% CI, 1.0 to 8.3; P=0.04), and a rapid diastolic deceleration time (OR, 5.4; 95% CI, 1.5 to 19.3; P=0.01) were independent predictors.\Question: Does coronary blood flow assessment after successful angioplasty for acute myocardial infarction predict the risk of long-term cardiac events?
[EX A]:
The CFV pattern appears to be an accurate predictor of long-term cardiac events in patients having undergone successful reopening of the IRA after AMI, identifying a subset of at-risk patients.
