Given the task definition and input, reply with output. Given a passage with a context and an answer, 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.

Context: Invasive infections caused by KPC-producing Klebsiella pneumoniae (KPCKP) are associated with very high mortality. Because infection is usually preceded by rectal colonization, we investigated if decolonization therapy (DT) with aminoglycosides had a protective effect in selected patients.', 'Patients with rectal colonization by colistin-resistant KPCKP who were at high risk of developing infection (because of neutropenia, surgery, previous recurrent KPCKP infections or multiple comorbidities) were followed for 180 days. Cox regression analysis including a propensity score was used to investigate the impact of the use of two intestinal decolonization regimens with oral aminoglycosides (gentamicin and neomycin/streptomycin) on mortality, risk of KPCKP infections and microbiological success. The study was registered with ClinicalTrials.gov (NCT02604849).', 'The study sample comprised 77 colonized patients, of which 44 (57.1%) received DT. At 180 days of follow-up, decolonization was associated with a lower risk of mortality in multivariate analyses (HR 0.18; 95% CI 0.06-0.55) and a lower risk of KPCKP infections (HR 0.14; 95% CI 0.02-0.83) and increased microbiological success (HR 4.06; 95% CI 1.06-15.6). Specifically, gentamicin oral therapy was associated with a lower risk of crude mortality (HR 0.15; 95% CI 0.04-0.54), a lower risk of KPCKP infections (HR 0.86; 95% CI 0.008-0.94) and increased microbiological response at 180 days of follow-up (HR 5.67; 95% CI 1.33-24.1). Neomycin/streptomycin therapy was only associated with a lower risk of crude mortality (HR 0.22; 95% CI 0.06-0.9).
Answer: Intestinal decolonization with aminoglycosides is associated with a reduction in crude mortality and KPCKP infections at 180 days after initiating treatment.
Is oral decontamination with aminoglycosides associated with lower risk of mortality and infections in high-risk patients colonized with colistin-resistant , KPC-producing Klebsiella pneumoniae?
