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: The aim of this study was to assess the effect of the implementation of evidence-based guidelines and subsequent feedback to surgeons in the management of acute pancreatitis.', 'An evidence-based Pancreatitis Proforma was developed. Data were prospectively recorded (01/06/2005-30/09/2007). Audit feedback (AFB) was performed at 9 months. A final analysis was performed comparing outcomes pre- and post-audit feedback.', '372 patients were included. Median age (range) was 57 (12-96) years. 168 (45.2%) patients were admitted pre-AFB. Post-AFB, there was a significant increase in the number of patients whose diagnosis was made within 48 hours (135/168 (80.4%) vs 189/204 (92.6%), p<0.001) and who underwent definitive treatment for mild biliary pancreatitis (33/61 (54.1%) vs 56/70 (80.0%), p=0.002). Post-AFB there was also a significant reduction in the number of computed tomography (CT) scans performed for patients with mild acute pancreatitis (23/85 (27.1%) vs 13/99 (13.1%), p=0.018). Mortality (9/168 (5.4%) vs 3/204 (1.4%), p=0.040) also decreased. On multivariate analysis, AFB was an independent factor for change in the use of CT scans (p=0.015) and management of patients with mild biliary pancreatitis (p=0.039).\Question: Is closing the audit loop necessary to achieve compliance with evidence-based guidelines in the management of acute pancreatitis?
[A]: For evidence-based guidelines to be effective, feedback to surgeons is necessary.


[Q]: Context: Although successful cochlear implantation of patients with deafness following meningitis is expected, long-term stability of electrical current requirements has not been systematically evaluated. This study evaluated changes in programming for patients deafened by bacterial meningitis and stability of auditory performance over time.', 'In this retrospective descriptive study, cochlear implant (CI) stimulation mode and performance of 14 patients deafened by meningitis were compared with those of an age-matched control group of patients deafened by other causes.', 'There were no significant differences in mean performance between the meningitis group and control group (P > 0.05). However, the postmeningitis group required progressively higher stimulation levels and higher programming modes over time as compared to the control group.\Question: Do changes in programming over time in postmeningitis cochlear implant users?
[A]: Even with deafness accompanied by labyrinthine ossification attributed to meningitis, neural elements were present and could be stimulated. Because increasing levels of stimulation were required over time, postmeningitic children with CIs, and those with cochlear ossification in particular, may need frequent programming adjustments to maintain performance.


[Q]: Context: Different apoptosis pathways activate caspase-3. In a study involving 27 patients with traumatic brain injury (TBI), higher caspase-3 levels were found in contusion brain tissue resected from non-survivors than from survivors. The objective of this study was to determine whether there is an association in TBI patients between serum caspase-3 levels (thus using an easier, quicker, less expensive and less invasive procedure) and mortality, in a larger series of patients.', 'We carried out a prospective, observational and multicenter study in six Spanish Hospital Intensive Care Units including 112 patients with severe TBI. All had Glasgow Coma Scale (GCS) scores lower than 9. Patients with an Injury Severity Score (ISS) in non-cranial aspects higher than 9 were excluded. Blood samples were collected on day 1 of TBI to measure serum caspas-3 levels. The endpoint was 30-day mortality.', 'We found that non-surviving patients (n = 31) showed higher (p = 0.003) serum caspase-3 levels compared to survivors (n = 81). Kaplan-Meier survival analysis showed a higher risk of death in TBI patients with serum caspase-3 levels >0.20 ng/mL than in patients with lower concentrations (Hazard Ratio = 3.15; 95% CI = 1.40 to 7.08; P < 0.001). Multiple logistic regression analysis showed that serum caspase-3 levels > 0.20 ng/mL were associated with mortality at 30 days in TBI patients controlling for Marshall CT classification, age and GCS (Odds ratio = 7.99; 95% CI = 2.116 to 36.744; P = 0.001).\Question: Are serum caspase-3 levels and mortality associated in patients with severe traumatic brain injury?
[A]:
The association between serum caspase-3 levels and mortality in TBI patients was the major novel finding of our study.
