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.

Question: Context: Intrathecal adenosine is antinociceptive under conditions of central sensitization, but not in response to acute stimuli in normals. The reasons for this selective circumstance of action remain unclear, but some evidence links adenosine's antinociceptive effects to release of norepinephrine by terminals in the spinal cord. The purpose of this study was to test whether spinal adenosine induces norepinephrine release selectively in settings of hypersensitivity.", 'Rats randomly assigned to spinal nerve ligation, sham operation, or no operation were anesthetized. A microdialysis fiber was implanted in the spinal cord dorsal horn at the L5-L6 level and perfused with artificial cerebrospinal fluid. After washout and a baseline sample period, adenosine at various concentrations was infused through the fiber for 150 min, and samples were collected every 15 min.', "In ligated, but not in sham or normal animals, adenosine perfusion increased norepinephrine in spinal cord microdialysates in a concentration-dependent manner. The effects of adenosine plateaued after 75 min and remained stable until the end of the experiment. Intravenous injection of selective adenosine A1 and A2 receptor antagonists revealed that adenosine's effect on spinal norepinephrine release was A1 receptor mediated.\Question: Does intraspinal adenosine induce spinal cord norepinephrine release in spinal nerve-ligated rats but not in normal or sham controls?

Answer: This is the first study to provide direct evidence that adenosine is able to release norepinephrine in spinal cord dorsal horns in living animals. However, this effect was only seen in animals after spinal nerve ligation. These data are consistent with behavioral studies demonstrating that adenosine's antinociceptive effects in rats after spinal nerve ligation is totally dependent on intact spinal noradrenergic terminals and can be blocked by spinal alpha 2-adrenergic receptor antagonists.


Question: Context: Little is known regarding the incidence rate of and factors associated with developing chronic kidney disease after continuous renal replacement therapy (CRRT) in acute kidney injury (AKI) patients. We investigated renal outcomes and the factors associated with incomplete renal recovery in AKI patients who received CRRT.', 'Between January 2011 and November 2013, 408 patients received CRRT in our intensive care unit. Of them, patients who had normal renal function before AKI and were discharged without maintenance renal replacement therapy (RRT) were included in this study. We examined the incidence of incomplete renal recovery with an estimated glomerular filtration rate < 60 mL/min/1.73 m(2) and factors that increased the risk of incomplete renal recovery after AKI.', 'In total, 56 AKI patients were discharged without further RRT and were followed for a mean of 8 months. Incomplete recovery of renal function was observed in 20 of the patients (35.7%). Multivariate analysis revealed old age and long duration of anuria as independent risk factors for incomplete renal recovery (odds ratio [OR], 1.231; 95% confidence interval [CI], 1.041 to 1.457; p = 0.015 and OR, 1.064; 95% CI, 1.001 to 1.131; p = 0.047, respectively). In a receiver operating characteristic curve analysis, a cut-off anuria duration of 24 hours could predict incomplete renal recovery after AKI with a sensitivity of 85.0% and a specificity of 66.7%.\Question: Does duration of anuria predict recovery of renal function after acute kidney injury requiring continuous renal replacement therapy?

Answer: The renal outcome of severe AKI requiring CRRT was poor even in patients without further RRT. Long-term monitoring of renal function is needed, especially in severe AKI patients who are old and have a long duration of anuria.


Question: Context: Nothing by mouth (NPO) is the standard treatment for small-bowel obstruction. Whether oral medications should be prohibited during treatment of adhesive, partial small-bowel obstruction is unclear. The goal of this study was to determine whether a combination of specific oral medications in adhesive, partial small-bowel obstruction will decrease the need for operative intervention.', 'Of 266 consecutive adult patients with partial small-bowel obstruction admitted at a tertiary medical center, 236 were randomized into 2 groups. Group I patients were treated with intravenous hydration, nasogastric tube decompression, and NPO. Group II patients were placed on intravenous hydration, nasogastric tube decompression, and oral fluids incorporating an oral laxative, a digestant, and a defoaming agent. We compared differences between the groups in (1) the number of patients having a successful nonoperative treatment, (2) complications, and (3) recurrence of symptoms.', 'A total of 116 and 120 patients comprised groups I and II, respectively. The number of patients treated successfully by a nonoperative approach was less in group I than in group II (77% vs 90%, P < .01). The complications and recurrence rate for groups I and II did not differ (4% vs 5% and 5% vs 4%, respectively).\Question: Do specific oral medications decrease the need for surgery in adhesive partial small-bowel obstruction?

Answer:
The NPO status for patients with adhesive, partial small-bowel obstruction may not be necessary. This cocktail of oral medications can decrease the need for operative intervention in patients with presumed adhesive, partial small-bowel obstruction.
