Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Question: Indoleamine 2,3 dioxygenase (IDO) degrades the essential amino acid tryptophan and has been shown to minimize rejection in animal models of renal transplantation. Ischemia-reperfusion injury (IRI) is unavoidable in renal transplantation and correlates with shorter graft survival times. Despite its favorable effects on rejection, there is evidence that IDO may facilitate renal IRI. Differentiating the negative impact of IDO on IRI from its pro-tolerant effects in allograft rejection is of clinical relevance. In these studies we hypothesized that constitutive IDO activity may influence renal genes associated with recovery from IRI, and that IDO inhibition may unmask these effects.', 'We examined the renal transcriptome in a rat model of IRI with and without IDO inhibition with 1-methyl-d-tryptophan (1-MT), and assessed for alterations in the gene expression signature.', 'These studies demonstrated that during recovery from renal IRI, pre-treatment with 1-MT alleviated alterations in 105 coding sequences associated with IRI, and in turn triggered new changes in 66 non-coding transcripts, the majority of which were represented by small nucleolar RNA.

Answer: Does indoleamine 2,3-dioxygenase inhibition alter the non-coding RNA transcriptome following renal ischemia-reperfusion injury?


Question: To assess the therapeutic effects of flexible magnets on pain perception, intramuscular swelling, range of motion, and muscular strength in individuals with a muscle microinjury.', 'This experiment was a single-blind, placebo study using a repeated-measures design. Subjects performed an intense exercise protocol to induce a muscle microinjury. After pretreatment measurements were recorded, subjects were randomly assigned to an experimental (magnet), placebo (imitation magnet), or control (no magnet) group. Posttreatment measurements were repeated at 24, 48, and 72 hours.', 'Forty-five healthy subjects participated in the study.', 'Subjects were measured repeatedly for pain perception, upper arm girth, range of motion, and static force production. Four separate univariate analyses of variances were used to reveal statistically significant mean (+/-SD) differences between variables over time. Interaction effects were analyzed using Scheffe post hoc analysis.', 'Analysis of variance revealed no statistically significant (P > .05) mean differences between conditions for any dependent pretreatment and posttreatment measurements. No significant interaction effects were demonstrated between conditions and times.

Answer: Are flexible magnets effective in decreasing pain perception and recovery time after muscle microinjury?


Question: Reducing central line-associated bloodstream infections (CLABSIs) poses a set of unique challenges in long-term acute care hospitals (LTACHS). Patients are often admitted to LTACHs with central lines in place from the previous hospitalization; thus, LTACHs lack control over insertion techniques and respective central line care and maintenance. This study aimed to demonstrate the impact of a methodical bathing approach with 2% chlorhexidine gluconate (CHG) cloths and a correlation with a reduced prevalence of CLABSIs in our LTACH population.', 'This retrospective observational quality initiative conducted in a 105-bed LTACH used plan-do-study-act methodology to assess the effects of a revised bathing approach using 2% CHG.', 'Statistical significance demonstrated a 65% reduction in CLABSI on the pilot unit after the 6-month initial trial. The results of the quality initiative were evaluated through the end of\xa02012.

Answer:
Does quality improvement intervention reduce episodes of long-term acute care hospital central line-associated infections?
