Example Input: An intense systemic inflammatory response is observed following reperfusion after cardiac arrest. Heparin-binding protein (HBP) is a granule protein released by neutrophils that intervenes in endothelial permeability regulation. In the present study, we investigated plasma levels of HBP in a large population of patients resuscitated from out-of-hospital cardiac arrest. We hypothesized that high circulating levels of HBP are associated with severity of post-cardiac arrest syndrome and poor outcome.', 'Plasma was obtained from 278 patients enrolled in a prospective multicenter observational study in 21 intensive care units (ICU) in Finland. HBP was assayed at ICU admission and 48h later. Multiple organ dysfunction syndrome (MODS) was defined as the 24h Sequential Organ Failure Assessment (SOFA) score12. ICU death and 12-month Cerebral Performance Category (CPC) were evaluated. Multiple linear and logistic regression tests and receiver operating characteristic curves with area under the curve (AUC) were performed.', 'Eighty-two percent of patients (229 of 278) survived to ICU discharge and 48% (133 of 276) to 1year with a favorable neurological outcome (CPC 1 or 2). At ICU admission, median plasma levels of HBP were markedly elevated, 15.4 [9.6-31.3] ng/mL, and persisted high 48h later, 14.8 [9.8-31.1] ng/mL. Admission levels of HBP were higher in patients who had higher 24h SOFA and cardiovascular SOFA score (p<0.0001) and in those who developed MODS compared to those who did not (29.3 [13.7-60.1] ng/mL vs. 13.6 [9.1-26.2] ng/mL, p<0.0001; AUC=0.700.04, p=0.0001). Admission levels of HBP were also higher in patients who died in ICU (31.0 [17.7-78.2] ng/mL) compared to those who survived (13.5 [9.1-25.5] ng/mL, p<0.0001) and in those with an unfavorable 12-month neurological outcome compared to those with a favorable one (18.9 [11.3-44.3] ng/mL vs. 12.8 [8.6-30.4] ng/mL, p<0.0001). Admission levels of HBP predicted early ICU death with an AUC of 0.740.04 (p<0.0001) and were independently associated with ICU death (OR [95 %CI] 1.607 [1.076-2.399], p=0.020), but not with unfavorable 12-month neurological outcome (OR [95 %CI] 1.154 [0.834-1.596], p=0.387).
Example Output: Is elevated plasma heparin-binding protein associated with early death after resuscitation from cardiac arrest?

Example Input: Epinephrine commonly is added to epidural opioids and local anesthetics, however, little is known about the fate of epidurally administered epinephrine. Studies have identified the epinephrine metabolizing enzyme, catechol-O-methyl transferase (COMT), in the cranial meninges of several species. The purpose of this study was to determine whether the spinal meninges also contain COMT and are capable of metabolizing epinephrine. If so, then the spinal meninges may have an important impact in limiting the bioavailability of epinephrine in both the spinal cord and epidural space.', 'Spinal meningeal specimens measuring 4 cm2 were obtained from monkeys (M. nemestrina) and farm-bred pigs and were incubated in bicarbonate-buffered mock cerebrospinal fluid. Epinephrine (200 micrograms base) was added at t = 0, and 200 min later, the mock cerebrospinal fluid was collected for metanephrine analysis. In separate experiments, pig meningeal specimens were separated into dura mater, pia-arachnoid mater, and pia mater, and the experiments were repeated to determine which meninx had the greatest COMT activity.', 'Metanephrine was produced by monkey meninges at the rate of 0.47 ng.min-1.cm-2 and by pig meninges at the rate of 0.23 ng.min-1.cm-2 (P > 0.05). The pia-arachnoid meninx produced metanephrine at a greater rate (4.48 +/- 0.46 ng.min-1.mg-1 tissue) than did the pia mater (1.3 +/- 0.15 ng.min-1.mg-1 tissue) or dura mater alone (1.82 +/- 0.23 ng.min-1.mg-1 tissue).
Example Output: Is epinephrine metabolized by the spinal meninges of monkeys and pigs?

Example Input: To test the hypothesis that hyporesponsiveness to ghrelin due to reduced growth hormone (GH) contributes to the aging-related hyperinflammatory state in sepsis.', 'Sepsis and septic shock are a serious problem, particularly in the geriatric population. Ghrelin is an endogenous ligand for the GH secretagogue receptor 1a (GHSR1a, ie, ghrelin receptor). The decline in GH with age is directly associated with many adverse changes that occur with aging. However, the role of GH, ghrelin, and GHSR1a in the age-associated vulnerability to sepsis remains unknown.', 'Male Fischer 344 rats (young: 3 months; aged: 24 months) were used. Plasma GH levels, ghrelin receptor expression, and neuronal activity in the parasympathostimulatory nuclei of the brain stem in normal young and aged animals were measured. Endotoxemia was induced by intravenous injection of lipopolysaccharide (LPS, 15 mg/kg BW).', 'While LPS-induced release of proinflammatory cytokines from macrophages isolated from aged rats decreased, LPS injection resulted in an in vivo hyperinflammatory state. GH levels were lower in aged rats, which was associated with lower expression of GHSR1a in the dorsal vagal complex and a decrease in parasympathostimulatory neuronal activity. GHSR1a antagonist elevated LPS-induced cytokine release in young rats. GH increased GHSR-1a expression in the dorsal vagal complex in aged rats. Coadministration of ghrelin and GH, but not ghrelin alone or GH alone, markedly reduced cytokine levels and organ injury after endotoxemia in aged rats, which was associated with significantly elevated parasympathostimulatory neuronal activity.
Example Output:
Does ghrelin hyporesponsiveness contribute to age-related hyperinflammation in septic shock?
