TASK DEFINITION: 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.
PROBLEM: Surgical site infections (SSIs) after colectomy for colon cancer (CC), Crohn's disease (CD), and diverticulitis (DD) significantly impact both the immediate postoperative course and long-term disease-specific outcomes. We aim to profile the effect of diagnosis on SSI after segmental colectomy using the National Surgical Quality Improvement Program (NSQIP) data set.", "NSQIP data from 2006 to 2011 were investigated, and segmental colectomy procedures performed for the diagnoses of Crohn's disease, DD, and colon malignancy were included. SSI complications were compared by diagnosis using univariate and multivariate analysis.", 'We included 35,557 colectomy cases in the analysis. CD had the highest rate of postoperative SSI (17 vs. 13% DD vs. 10% CC; p\u2009<\u20090.001). Using CC as the comparison group and controlling for multiple variables, the multivariate analysis showed that the CD group had an increased risk for acquiring at least one SSI (odds ratio (OR)\u2009=\u20091.38, p\u2009≤\u20090.001), deep incisional SSI (OR\u2009=\u20091.85, p\u2009=\u20090.03), and organ space SSI (OR\u2009=\u20091.51, p\u2009=\u20090.02).

SOLUTION: Is crohn 's disease but not diverticulitis an independent risk factor for surgical site infections in colectomy?

PROBLEM: Brain-derived neurotrophic factor (BDNF) acts rapidly to modulate synaptic neurotransmission in the brain. Although present in neurons, glial cells, and mucosal cells of the colon, and in higher concentrations than in brain, the action of BDNF in gut have not been characterized. The aim of this study was to identify the role of BDNF in mediating the peristaltic reflex.', 'BDNF and a specific antiserum were examined for their effects on the peristaltic reflex and release of the sensory mediators serotonin and calcitonin gene-related peptide in rat colon. The peristaltic reflex and release of serotonin and calcitonin gene-related peptide were also examined in genetically modified mice (BDNF(+/-)) with reduced levels of BDNF.', 'Endogenous brain-derived neurotrophic factor was released into the sensory compartment in a stimulus-dependent manner during the peristaltic reflex induced by mucosal stimulation but not muscle stretch. BDNF stimulated and immunoneutralization of endogenous BDNF reduced ascending contraction and descending relaxation of circular muscle and release of serotonin and calcitonin gene-related peptide during the peristaltic reflex induced by mucosal stimulation but not muscle stretch. The peristaltic reflex and release of serotonin and calcitonin gene-related peptide during the peristaltic reflex induced by mucosal stimulation but not muscle stretch were significantly reduced in BDNF(+/-) mice.

SOLUTION: Does brain-derived neurotrophic factor augment peristalsis by augmenting 5-HT and calcitonin gene-related peptide release?

PROBLEM: The regulation of strong emotions has important implications for health, particularly among individuals with chronic illness. We focus this brief review on effective psychosocial interventions that emphasize and teach skills to improve emotion regulation in the context of health-related outcomes.', 'Recent work in the area of emotion-regulation interventions has tested the effects of emotion-regulation family therapy, group-based emotion-regulation psychotherapy, expressive writing, and school-based prevention programs. Emotion-regulation psychotherapy for families shows some benefits for both patients and their family members. Group emotion-regulation interventions and expressive writing result in physical and psychosocial improvement for patients with medical or psychiatric illness. School-based programs show improved emotion knowledge, emotion regulation, and emotional competence, relative to standard academic curricula and existing prevention programs.

SOLUTION:
Does recent evidence support emotion-regulation interventions for improving health in at-risk and clinical populations?
