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 Input:
Context: To examine whether differences emerged when the Chinese version of the Movement-Specific Reinvestment Scale (MSRS-C) was administered to community-dwelling older adults with instructions to respond in the context of "general" movements, walking, using chopsticks or dressing. Furthermore, the difference between the six-point Likert scale and four-point Likert scale response formats of the MSRS-C was investigated.', 'The study was implemented in the community of Hong Kong with 52 older adults (mean age 77.4 years). Telephone interviews were carried out on two occasions for each participant. Participants provided a verbal response to each of 10 questions from the MSRS-C with different response formats (i.e., six-point or four-point Likert Scales) and different instructions in the response context (i.e. general, walking, using chopsticks, dressing). The sequence of response format and context was randomized for each participant.', 'Older fallers scored significantly higher on the MSRS-C (general) with six-point or four-point response formats than non-fallers. The MSRS-C (general) and MSRS-C (walking) were not statistically different, and showed good discriminative power for previous older fall status (older fallers or older non-fallers). However, MSRS-C (chopsticks) and MSRS-C (dressing) failed to differentiate older fallers from older non-fallers.\Question: Do instructions influence response to the Chinese version of the Movement-Specific Reinvestment Scale in community-dwelling older adults?

Ex Output:
Both the MSRS-C (general) and MSRS-C (walking) with a six-point or a four-point response format showed good discrimination of older fallers from non-fallers. Older adults might respond to the MSRS-C with respect to the most challenging movements (e.g. fall-related movements) in their daily living. Geriatr Gerontol Int 2015; : -.

Context: Crohn's disease is a heterogeneous inflammatory bowel disease. The impact of age at diagnosis on the clinical course of patients varies widely as reported in the Western literature. Using the Vienna Classification, we seek to determine whether young Crohn's disease patients in an Asian population followed a different clinical course than old patients.", "The case records of 100 Crohn's disease patients who were treated at the Inflammatory Bowel Disease Center, Singapore General Hospital, were studied retrospectively. The age group and location of disease and behavior according to the Vienna classification were determined at diagnosis.", 'A1 group (age <40 years) defined as "young" and A2 group (age > or =40) defined as "old" contained 65 and 35 patients, respectively. Median age for the young group was 27.4 years and that for the old group was 52.6 years. Of the young patients, 66.7% flared at least once compared with 28.6% of the old patients, odds ratio of 5.0 (P < 0.001). Young patients were more likely to be steroid dependent (20.0% of A1 versus 8.6% of A2, P = 0.14), received azathioprine (38.5% of A1 versus 5.7% of A2, P < 0.001) and experienced complications (31% of A1 versus 20% of A2, P = 0.25)-numerically higher rates that did not reach statistical significance. There was no significant difference between the age groups for the location and behavior of disease as well as requirement for surgery.\Question: Does crohn 's disease run a more aggressive course in young Asian patients?

Ex Output:
In this first Asian study looking specifically at the impact of age at diagnosis of Crohn's disease, we found that young patients underwent a more aggressive clinical course.

Ex Input:
Context: This study was performed to assess whether there is any change in the T cell cytokine pattern in early rheumatoid arthritis (RA) patients treated with methotrexate (MTX) and whether the lymphocytic cytokine pattern correlates with disease activity.', 'Eight patients with RA (disease duration < six months) were studied serially before, after three, and after six to nine months of treatment with MTX for the cytokines tumour necrosis factor alpha (TNFalpha), interferon gamma (IFNgamma), interleukin 4 (IL4) and interleukin 10 (IL10) by intracellular staining of T cells derived from peripheral blood. Response to treatment was assessed by the modified disease activitiy score.', 'The clincial response was accompanied by a significant decrease of TNFalpha positive CD4(+) T cells from a median of 8.53% (interquartile range 5.83-10.91%) before treatment to 6.17% (2.15-6.81%) after six to nine months of treatment (p=0.021). Inversely, IL10 positive T cells increased from a median of 0.65% (interquartile range 0.6-0.93%) to a median of 1. 3% (1.22%-1.58%) after six to nine months of treatment (p=0.009). No significant change in the percentage of INFgamma positive T cells and a small decrease of IL4 positive T cells during treatment were observed. The percentage of IL4 positive CD4(+) T cells before treatment correlated with disease activity after six to nine months (r= -0.7066; p=0.05).\Question: Is response to methotrexate in early rheumatoid arthritis associated with a decrease of T cell derived tumour necrosis factor alpha , increase of interleukin 10 , and predicted by the initial concentration of interleukin 4?

Ex Output:
During treatment of RA with MTX the percentage of TNFalpha producing T cells decreases whereas that of IL10 producing T cells increases. This may affect macrophage activation and, therefore, may represent a regulatory mechanism relevant to disease remission. Furthermore, the percentage of IL4 positive CD4(+) T cells at disease onset may be a useful prognostic marker.
