TASK DEFINITION: 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.
PROBLEM: The purpose of this study was to determine whether four types of professionalism deficiencies in medical students identified during a first-year course on doctor-patient relationships might predict poor performance in third-year clerkships.', 'Preceptors identified students who had deficiencies in interviewing patients: extreme shyness, poor process skills, paternalism, or a negative attitude toward interviewing. Deficient students were matched by academic ability to a control group. Performance on third-year clerkships was compared.', 'Students with paternalistic behavior or negative attitudes had significantly lower third-year grades.

SOLUTION: Do professionalism deficiencies in a first-quarter doctor-patient relationship course predict poor clinical performance in medical school?

PROBLEM: Asthma is a multi-factorial inflammatory disease associated with increased oxidative stress and altered antioxidant defences. We have evaluated the effect of choline on oxidative stress in a mouse model of airway disease.', 'Balb/c mice were sensitised with 100 microg of ovalbumin on days 0 and 14, and challenged with aerosolized ovalbumin on days 25-27. Mice were administered 1 mg kg(-1) of choline via oral gavage or intranasal route on days 14-27. Mice were also administered 100 mg kg(-1) of alpha-lipoic acid as standard antioxidant. Total cell counts, eosinophils and eosinophil peroxidase (EPO) activity were determined in bronchoalveolar lavage (BAL) fluid. Reactive oxygen species (ROS), lipid peroxidation and isoprostanes levels were measured in BAL fluid. IL-13 and tumour necrosis factor-alpha (TNF-alpha) levels were also measured in BAL fluid and spleen cell culture supernatant. Nuclear factor kappaB (NFkappaB) p65 protein expression was measured after last ovalbumin challenge in nuclear and cytosolic extracts of lungs.', 'Compared with ovalbumin-challenged mice, choline and alpha-lipoic acid treated mice had significantly reduced eosinophilic infiltration and EPO activity in BAL fluid. Choline and alpha-lipoic acid treatment reduced ROS production and isoprostanes level significantly in BAL fluid and thus suppressed oxidative stress. Choline and alpha-lipoic acid administration by either route decreased lipid peroxidation levels and down regulated NFkappaB activity. Further, choline and/or alpha-lipoic acid treatment suppressed TNF-alpha level significantly as compared with that of ovalbumin-challenged mice.

SOLUTION: Does choline supplementation reduce oxidative stress in mouse model of allergic airway disease?

PROBLEM: It is now well accepted that traumatic white matter injury constitutes a critical determinant of post-traumatic functional impairment. However, the contribution of preexisting white matter rarefaction on outcome following traumatic brain injury (TBI) is unknown. Hence, we sought to determine whether the burden of preexisting leukoaraiosis of presumed ischemic origin is independently associated with outcome after TBI.', 'We retrospectively analyzed consecutive, prospectively enrolled patients of ≥50\xa0years (n\xa0=\xa0136) who were admitted to a single neurological/trauma intensive care unit. Supratentorial white matter hypoattenuation on head CT was graded on a 5-point scale (range 0-4) reflecting increasing severity of leukoaraiosis. Outcome was ascertained according to the modified Rankin Scale (mRS) and Glasgow outcome scale (GOS) at 3 and 12\xa0months, respectively.', 'After adjustment for other factors, leukoaraiosis severity was significantly associated with a poor outcome at 3 and 12\xa0months defined as mRS 3-6 and GOS 1-3, respectively. The independent association between leukoaraiosis and poor outcome remained when the analysis was restricted to patients who survived up to 3\xa0months, had moderate-to-severe TBI [enrollment Glasgow Coma Scale (GCS) ≤12; p\xa0=\xa00.001], or had mild TBI (GCS 13-15; p\xa0=\xa00.002), respectively.

SOLUTION:
Does severe leukoaraiosis portend a poor outcome after traumatic brain injury?
