Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

[EX Q]: Episodic memory enables us to consciously recollect personally experienced past events. Memory performance is reduced in patients with mild cognitive impairment (MCI), an at-risk condition for Alzheimer's disease (AD).", 'We used functional MRI (fMRI) to compare brain activity during memory encoding in 29 healthy elderly subjects (mean age 67.7 (SD 5.4) years) and 21 patients with MCI (mean age 69.7 (SD 7.0) years). Subjects remembered a list of words while fMRI data were acquired. Later, they had to recognise these words among a list of distractor words. The use of an event related paradigm made it possible to selectively analyse successfully encoded items in each individual. We compared activation for successfully encoded words between healthy elderly subjects and patients with MCI.', 'The main intergroup difference was found in the left hippocampus and surrounding medial temporal lobe (MTL) regions for the patients with MCI compared with healthy subjects during successful encoding.
[EX A]: Is hippocampal activation in patients with mild cognitive impairment necessary for successful memory encoding?

[EX Q]: We aimed to test the outcome-predictive power of routine fasting glucose (FG) obtained at second day after onset in intravenous thrombolysis (IVT) acute ischemic stroke (AIS) patients.', 'We identified AIS patients presenting to our institution between December 2011 and July 2013 within 4.5 hours of onset, who received admission glucose (AG) before IVT, FG, and glycated hemoglobin (HbA1c) the second day after admission, from our prospectively recorded stroke database. Multivariate logistic regression was used to assess the association of FG and 90-day modified Rankin Scale (mRS).', 'Between December 2011 and July 2013, a total of 166 AIS patients received intravenous plasminogen activator. Of those, 119 patients who have AG before IVT, FG, and HbA1c the second day were included in the study. FG independently predicted 90-day clinical unfavorable outcome (mRS, 3-6 with an odds ratio of 1.576; 95% confidence interval [CI], 1.053-2.358; P = .027). This association was not significant in AG (P = .714), HbA1c (P = .655), and history of diabetes (P = .547). In receiver operating characteristic analysis, increased FG was associated with 90-day mRS (3-6) with an area under curve of .72, (95% CI, .65-.9; P = .001).
[EX A]: Is higher fasting glucose next day after intravenous thrombolysis independently associated with poor outcome in acute ischemic stroke?

[EX Q]: Uninsured and underinsured patients are reported to be at an increased risk for impaired access to healthcare, delayed medical treatment, and the receipt of substandard care. These differences in care may result in disparities in surgical outcomes among patients with different types of insurance. In the current study, the authors examined associations between the insurance provider and short-term surgical outcomes after surgery for colorectal carcinoma and evaluated the extent to which two risk factors (comorbid disease and admission type) might explain any observed association.', 'The authors conducted a nationally representative retrospective cohort study of 13,415 adults ages 40-64 years who were admitted for surgery for colorectal carcinoma to hospitals that participated in the Agency for Healthcare Research and Quality Healthcare Cost and Utilization Project National Inpatient Sample, releases 6 and 7, in 1997 and 1998. Multivariate logistic regression models were developed to describe the correlations between insurance status and the risks of a postoperative complication or postoperative death after adjustment for socioeconomic factors, comorbid conditions, and admission type.', 'Uninsured and Medicaid patients were found to have more emergent admissions and more comorbid disease compared with patients with private health insurance. Patients without private health insurance had higher rates of postoperative complications and in-hospital death compared with those patients with private insurance. After adjusting for patient and hospital characteristics, patients with Medicaid were found to be 22% more likely to develop a complication during their hospital admission (odds ratio [OR] of 1.22; 95% confidence interval [95%CI], 1.06-1.40) and 57% more likely to die postoperatively (OR of 1.57; 95% CI, 1.01-2.42) compared with patients with private insurance.
