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.

Input: Consider Input: GM-CSF has broad clinical applicability as a potent myelopoietic stimulator. However, its function is not restricted to the myelopoietic system and several observations suggest that GM-CSF may interfere with the hemostatic balance. In order to assess whether GM-CSF has any influence on hemostasis, we evaluated some coagulative and fibrinolytic parameters in patients treated with GM-CSF following chemotherapy.', 'Fibrinolytic activity (FA), fibrinogen and D-dimer were evaluated before and after high-dose cyclophosphamide in 6 patients additionally treated with GM-CSF and in 5 control patients; moreover, tissue plasminogen activator (tPA) was assayed in those treated with GM-CSF. Comparative in vitro analysis was performed on cultured endothelial cells before and after exposure to GM-CSF.', 'Control patients showed a significant decrease in plasma FA after chemotherapy compared to basal values (FA/mm2: 15.6 +/- 2.1 at day + 2 and 20.8 +/- 19 at day + 4 vs. 103.8 +/- 64.2 at day 0; p < 0.005); conversely, no FA reduction was observed in GM-CSF-treated subjects. In this latter group a marked increase in tPA antigen was seen, consistent with enhanced FA. No significant changes in plasma D-dimer and fibrinogen values were detected in the two groups. tPA, urokinase-type plasminogen activator, PAI-1 and procoagulant activity were evaluated in vitro on cultured human endothelial cells and found to be unchanged following GM-CSF addition.

Output: Is reduction of plasma fibrinolytic activity following high-dose cyclophosphamide neutralized in vivo by GM-CSF administration?

Input: Consider Input: Although it has been postulated that liver injury results in impaired clearance of bacteria from the blood, no prior study has evaluated hepatic bacterial clearance during sepsis.', 'We hypothesized that liver injury during the evolution of sepsis would result in impaired hepatic bacterial clearance.', 'Mild and severe bacteremia were generated in C57BL/6 mice by low- and high-dose intratracheal inoculation with Pseudomonas aeruginosa.', 'The mortality rates with mild and severe bacteremia were 20% and 60%, respectively. Hepatic bacterial clearance was preserved throughout the evolution of mild bacteremia but was lost late with severe bacteremia. The loss of hepatic bacterial clearance resulted in increased systemic bacteremia and mortality. Pretreatment with a caspase inhibitor resulted in preservation of hepatic bacterial clearance with severe bacteremia and eventual control of the bacteremia. When Kupffer cells were ablated before the onset of bacteremia, there was a loss of hepatic bacterial clearance. This converted an initially mild bacteremia into severe bacteremia with increased organ injury and mortality.

Output: Does severe bacteremia result in a loss of hepatic bacterial clearance?

Input: Consider Input: Multiple population-based studies have suggested increasing omission of radiation therapy in favor of alternative treatment strategies in lymphomas, with an associated negative impact on survival. Radiation therapy has long been considered the standard management for many mucosa-associated lymphoid tissue lymphomas. Thus, we aimed to evaluate patterns of treatment utilization and survival.', 'A retrospective analysis based on the National Cancer Database was performed on 22,378 patients with splenic, nodal, or extranodal stage I-II marginal zone lymphoma diagnosed between 1998 and 2012. A logistic regression model was used to assess the association between sociodemographic, tumor, and treatment characteristics and the utilization of radiation therapy. Multivariate propensity score-adjusted Cox proportional hazards models were performed to identify factors independently associated with overall survival (OS).', 'Of 22,378 patients, 82% had stage I disease, 77% had extranodal mucosa-associated lymphoid tissue lymphoma, 5% had splenic marginal zone lymphoma, and 64% were older than 60 years. Radiation therapy utilization decreased from a peak of 39% in 2007 to 33% in 2011 (P < .001), with a corresponding significant increase in systemic therapy utilization. Radiation therapy was associated with a 5- and 10-year OS of 86.7% and 68.8% compared with 78.3% and 54.3% for no radiation therapy (P < .001). On multivariate propensity score-adjusted survival analysis, radiation therapy remained independently associated with improved OS (hazard of death, 0.75; 95% confidence interval, 0.65-0.85; P < .001).
Output: Does underutilization of radiation therapy in early-stage marginal zone lymphoma negatively impact overall survival?
