TASK DEFINITION: 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.
PROBLEM: 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?

SOLUTION: 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; : -.

PROBLEM: Context: In diabetics with end-stage renal disease (ESRD), risk of death has been reported to be non-constant after the first dialysis, and different outcomes have been observed between genders. We assessed the impact of type 2 diabetes (T2DM) on mortality in dialysis regarding its differential effect by gender using time-dependent analyses.', 'All T2DM and non-diabetic (no-DM) patients who started dialysis in two renal units in Lyon, France, between January 1, 1995, and December 31, 2007, were included. In multivariate analyses, the Cox model and Shoenfeld residual approach were used to assess the effect of T2DM on dialysis mortality by gender.', 'We included 235 T2DM (males: 57.9%) and 480 no-DM (males: 65.6%) patients. In males, the adjusted hazard ratio (aHR) for death in T2DM versus no-DM was 0.83 (p = 0.20) and was constant over time after the first renal replacement therapy (RRT) (p = 0.88). In females, aHR for death in T2DM versus no-DM patients was not constant over time (p = 0.002). It was 0.64 (p = 0.13) within the first year after the first RRT and 2.10 (p = 0.002) after the first year. Evolutions with time of these aHR by gender were significantly different (p = 0.009).\Question: Does the Impact of type 2 diabetes on mortality in end-stage renal disease patients differ between genders?

SOLUTION: T2DM was associated with death only in females. This association was not constant over time after the first dialysis.

PROBLEM: Context: Ginkgo biloba extract, EGb761, is one of the most commonly used herbal supplements throughout Western society. It has been used in the treatment of various common geriatric complaints including short-term memory loss. We showed that acute systemic administration of EGb761 enhanced fear-potentiated startle (FPS) in rats. Little is known about the behavioral effects of centrally administered EGb761 on FPS.', 'The current study was performed to evaluate the involvement of basolateral nucleus of amygdala (BLA) in the EGb761 facilitation effect on FPS.', "Male adult SD rats were used. EGb761 was infused into cerebroventricle or basolateral nucleus of amygdala 10 min prior to fear conditioning. Animals were then tested for FPS 24 h later. Results showed that (1) intra-cerebroventricular infusion of EGb761 (0.1, 1.0, or 3.0 microg/3.0 microl per side, bilaterally) and intra-amygdaloid infusion of EGb761 (1.0, 14.0, or 28.0 ng/microl per side, bilaterally) 30 and 10 min prior to fear conditioning, respectively, facilitated FPS in a dose-dependent manner. (2) Administration of EGb761 did not impair an animal's basal startle response or pain perception. (3) Subsequent control experiment's results indicated that the facilitation effect of EGb761 on the acquisition was not due to anxiogenic effect or non-specific effect.\Question: Does intra-amygdaloid infusion of Ginkgo biloba leaf extract ( EGb761 ) facilitate fear-potentiated startle in rats?

SOLUTION:
These results suggested that a single dose of EGb761 also has memory-enhancing effects in young animals. In addition, BLA is the central locus for EGb761 facilitation effect on FPS.
