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: Sufentanil is an intravenous opioid often used as a component of anesthesia during neurosurgical procedures. However, the effects of sufentanil on intracranial pressure in patients with diminished intracranial compliance are not well established, and remain controversial.', 'Ten patients with head trauma, in each of whom the trachea was intubated, were studied for the effects of sufentanil on intracranial pressure (ICP) and on cerebral perfusion pressure (CPP). In all patients, ICP monitoring was instituted before the study. Sedation was obtained using a propofol infusion, and paralysis was achieved with vecuronium. After obtaining control of ICP (between 15 and 25 mmHg) hemodynamic values and blood gas tensions (PaCO2 between 30 and 35 mmHg), the level of sedation was deepened with an intravenous injection of sufentanil (1 microgram/kg over 6 min), followed by an infusion of 0.005 microgram.kg-1min-1. Mean arterial pressure (MAP), ICP (fiberoptic intracranial pressure monitor), and end-tidal CO2 were continuously measured and recorded at 1-min intervals throughout the 30-min study period.', 'Sufentanil injection was associated with a statistically significant increase in ICP of 9 +/- 7 mmHg (+ 53%), which peaked at 5 min. Then ICP gradually decreased and returned to baseline after 15 min. This was accompanied by a significant decrease in MAP (24% decrease) and, thus, CPP (38% decrease). After 5 min, MAP and CPP gradually increased, but remained significantly decreased throughout the study.\Question: Does sufentanil increase intracranial pressure in patients with head trauma?

A: The results of the current study indicate that caution should be exercised in the administration of sufentanil bolus to patients with abnormal intracranial elastance, particularly if ICP is significantly increased.

Q: Context: Liraglutide improves the metabolic control of diabetic animals after islet transplantation. However, the mechanisms underlying this effect remain unknown. The objective of this study was to evaluate the anti-inflammatory and anti-oxidative properties of liraglutide on rat pancreatic islets in vitro and in vivo.', 'In vitro, rat islets were incubated with 10molL', 'Islet viability and function were preserved and enhanced with liraglutide treatment. Liraglutide decreased CCL2 and IL-6 secretion and macrophage activation after 12h of culture, while IL-10 secretion was unchanged. However, intracellular levels of ROS were increased with liraglutide treatment at 12h. This result was correlated with an increase of anti-oxidative capacity. In vivo, liraglutide decreased macrophage infiltration and reduced fasting blood glucose in transplanted rats.\Question: Is improvement of islet graft function using liraglutide correlated with its anti-inflammatory properties?

A: The beneficial effects of liraglutide on pancreatic islets appear to be linked to its anti-inflammatory and anti-oxidative properties. These findings indicated that analogues of glucagon-like peptide-1 could be used to improve graft survival.

Q: Context: We examined whether patients with a diagnosis of fibromyalgia have an increased risk of coronary heart disease (CHD), compared with age- and sex-matched control patients. We hypothesized that patients diagnosed with fibromyalgia are at increased risk of adverse coronary events.', 'Using a matched-cohort study design, we analyzed data retrieved from the Longitudinal Health Insurance Database 2000 released by the National Health Research Institute, Taiwan. The Longitudinal Health Insurance Database 2000 includes medical claims data and registration files for 1 million enrollees randomly selected from the 2000 Registry for Beneficiaries (n = 23.72 million) of the National Health Insurance program. Patients treated for fibromyalgia at least once a month for 3 consecutive months following their initial diagnosis were enrolled in our study. The primary end point was the composite of CHD events, including percutaneous coronary interventions and coronary artery bypass grafting procedures. A propensity score was estimated by a logistic regression method, in which the fibromyalgia status was regressed on baseline prognostic factors. The hazard ratios and the 95% confidence intervals were estimated using multivariate Cox proportional-hazards regression models while adjusting for the propensity score.', 'After adjusting for the propensity score, the patients with fibromyalgia showed a significantly higher subsequent risk of a CHD event (hazard ratio, 2.11; 95% confidence interval, 1.46-3.05; P < 0.001) than the patients without fibromyalgia.\Question: Is fibromyalgia associated with coronary heart disease : a population-based cohort study?

A:
An association between fibromyalgia and CHD appears to exist.
