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.

Q: Context: "Virtual fracture clinics" have been reported as a safe and effective alternative to the traditional fracture clinic. Robust protocols are used to identify cases that do not require further review, with the remainder triaged to the most appropriate subspecialist at the optimum time for review. The objective of this study was to perform a "top-down" analysis of the cost effectiveness of this virtual fracture clinic pathway.', 'National Health Service financial returns relating to our institution were examined for the time period 2009 to 2014 which spanned the service redesign.', 'The total staffing costs rose by 4% over the time period (from 1 744 933 to 1 811 301) compared with a national increase of 16%. The total outpatient department rate of attendance fell by 15% compared with a national fall of 5%. Had our local costs increased in line with the national average, an excess expenditure of 212 705 would have been required for staffing costs.\Question: Does fracture clinic redesign reduce the cost of outpatient orthopaedic trauma care?

A: The virtual fracture clinic system was associated with less overall use of staff resources in comparison to national cost data. Adoption of this system nationally may have the potential to achieve significant cost savings.Cite this article: P. J. Jenkins.

Q: Context: The expression of growth-associated protein 43 (GAP-43), a marker of axonal growth, in the dorsal root ganglion (DRG) neurons innervating the lumbar intervertebral disc was assessed using the retrograde tracing method and immunohistochemistry.', 'To study whether disc inflammation affects GAP-43 expression in DRG neurons innervating the disc in rats.', 'Persistent inflammation and nerve ingrowth into the inner layer of degenerated discs can be a cause of discogenic pain. Although the presence of GAP-43-expressing nerve fibers in painful discs has been reported, the expression of GAP-43 in DRG neurons innervating the disc has not been studied.', "Seven days after the application of Fluoro-Gold to the L5-L6 disc, 50 microL of saline (n = 10, control group) or complete Freund's adjuvant (n = 10, inflammatory group) was applied to the disc in rats. Ten days after the Fluoro-Gold application, T13-L5 DRGs were double-stained with GAP-43 and either calcitonin gene-related peptide or isolectin B4 (IB4).", 'The percentage of Fluoro-Gold-labeled neurons that were positive for GAP-43 was significantly higher in the inflammatory group (44%) than in the control group (24%, P < 0.001). In both groups, the majority of GAP-43-positive neurons were small and positive for calcitonin gene-related peptide but not IB4.\Question: Does disc inflammation potentially promote axonal regeneration of dorsal root ganglion neurons innervating lumbar intervertebral disc in rats?

A: The present results suggest that disc inflammation potentially promotes axonal growth of DRG neurons innervating the disc. In light of the strong correlation between the expression of calcitonin gene-related peptide and nerve growth factor receptor, it is most likely that nerve growth factor-sensitive DRG neurons extend their axons following disc inflammation.

Q: Context: Hostility may influence racial disparities in cardiovascular disease through differential associations with cardiovascular risk factors. This study explored racial variations in relations between hostility and selected cardiovascular risk factors.', 'Cook-Medley Hostility (Ho) scores and 11 risk factors were examined among 66 healthy, White and African American young adults.', 'Controlling for age, gender, and body mass index, the interaction of hostility and race yielded significant (or marginal) associations with resting systolic and diastolic blood pressure (SBP, DBP), cardiac index (CI; i.e. cardiac output adjusted for body size), total peripheral resistance (TPR), insulin (INS), triglycerides (TG) and percent body fat (PBF). Contributing substantial variance, hostility was positively associated with SBP, DBP, TPR, TG and INS, and negatively associated with CI among African Americans. Conversely, hostility was negatively associated with TPR and PBF among Whites.\Question: Does hostility differentially predict cardiovascular risk factors in African American and White young adults?

A:
Hostility may confer greater cardiovascular risk among young African Americans than Whites.
