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]: Video-EEG monitoring in the epilepsy monitoring unit (EMU) is a limited clinical resource. Knowledge of the predicting factors for length of stay (LOS) in the EMU may allow providers to more efficiently utilize EMU bed space.', 'The records for all consecutive admissions to the EMU at the University of Colorado Hospital between December 1, 2010 and May 31, 2011 (n = 142) were retrospectively reviewed.', 'Univariate analyses focusing on variables known prior to admission showed that EMU LOS (in hours) was not significantly correlated with patient age, number of event types, or number of antiepileptic drugs at admission. Patients who were admitted to the EMU for event characterization had statistically significantly shorter average LOS than patients who had been admitted as a part of a presurgical evaluation. Patients who reported < = 1 seizure per week had a statistically significantly higher average LOS than patients who reported >= 1 seizure per day. These variables were also significantly predictive of total LOS (p < 0.0001 and p = 0.03, respectively) in multivariate analysis.
[EX A]: Do pre-admission clinical factors affect length of stay in the epilepsy monitoring unit?

[EX Q]: Both diet quality (DQ) and physical activity (PA) have been shown to play a role in the prevention of functional capacity (FC) decline. Because older adults (OA) with T2D are at a higher risk of FC decline compared to their non-diabetic counterparts, our aim was to determine if DQ alone, or combined with PA is associated with FC decline in OA with T2D over a 3-year follow-up in a secondary analysis of the NuAge cohort.', "In 159 OA with T2D (mean age=75 years), FC change was calculated as the difference in FC scores at T1 and T4 measured by the SMAF (Système de Mesure de l'Autonomie Fonctionnelle). Baseline DQ was calculated from three non-consecutive 24-h dietary recalls collected at T1 using the validated Canadian Healthy Eating Index (C-HEI). PA change was calculated from Physical Activity Scale for the Elderly (PASE) as T4-T1. Associations were evaluated between FC decline and four combinations of variables: C-HEI score < or ≥70 with PASE change < or > median and analyzed by GLM while controlling for covariates.", 'Neither DQ alone nor DQ combined with PA change were associated with FC decline over follow-up.
[EX A]: Is decline in functional capacity unaffected by diet quality alone or in combination with physical activity among generally healthy older adults with T2D from the NuAge cohort?

[EX Q]: Complement activation is considered a major mechanism in innate immunity. Although it is mainly involved in initiating inflammation, recent data reported its involvement in other processes such as tissue regeneration. In the dental pulp, complement C5a fragment has been shown to be involved in the recruitment of dental pulp stem cells (DPSCs). This study sought to investigate the possible role of C3a, another complement fragment, in the early steps of dentin-pulp regeneration.', 'Expression of C3a receptor (C3aR) was investigated by immunofluorescence and reverse transcriptase polymerase chain reaction on cultured pulp fibroblasts, STRO-1-sorted DPSCs, as well as on human tooth sections in\xa0vivo. The effect of C3a on proliferation of both DPSCs and pulp fibroblasts was investigated by MTT assay. Cell migration under a C3a gradient was investigated by using microfluidic chemotaxis chambers.', 'C3aR was expressed in\xa0vivo as well as in cultured pulp fibroblasts co-expressing fibroblast surface protein and in DPSCs co-expressing STRO-1. Addition of recombinant C3a induced a significant proliferation of both cell types. When subjected to a C3a gradient, DPSCs were mobilized but not specifically recruited, whereas pulp fibroblasts were specifically recruited following a C3a gradient.
