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: Corticosteroids are a critical component of therapy for acute lymphoblastic leukemia (ALL) but are associated with late effects, such as osteoporosis. Risk factors remain poorly defined. Because CRHR1 polymorphisms have been associated with other corticosteroid effects, our goal was to define whether CRHR1 polymorphisms predict which patients with ALL are likely to develop bone mineral deficits.', 'The mean bone mineral density z scores of 309 long-term survivors of ALL were determined by quantitative computed tomography of the trabecular lumbar spine. We analyzed whether CRHR1 genotypes, adjusted for sex, ALL treatment regimen, and weight, could predict bone density.', 'We found that three single nucleotide polymorphisms (SNPs), all in linkage disequilibrium, were associated with bone density in a sex-specific manner. Bone density was lower in males (P = .001), in nonblack patients (P < .08), in those who were not overweight (P < .001), and in those who received intensive antimetabolites and glucocorticoids (P < .001). After adjustment for these features, the G allele at the rs1876828 SNP was associated with lower z scores (P = .02) in males but tended to have the opposite association in females (P = .09).
Answer: CRHR1 polymorphisms may impact the risk of bone density deficits in patients treated with corticosteroids and antimetabolites in a sex-specific manner.
Do cRHR1 polymorphisms predict bone density in survivors of acute lymphoblastic leukemia?

Context: Inflammatory risk factors in childhood, e.g. obesity, impact on carotid artery intima media thickness (CIMT), an early indicator of atherosclerosis. Little is known on potential infectious origins in childhood. We investigated the association between number of reported different childhood infectious diseases and CIMT in adolescence.', "288 SAPALDIA offspring (8-21years) underwent a clinical examination in 2010-2011: anthropometry, blood pressure, CIMT, blood draw (cardiovascular biomarkers, cotinine). Offspring and parents gave information on individuals' and family health, child's vaccination status, infectious diseases and other early life factors. Life-time prevalence of bronchitis, pneumonia, tonsillitis, otitis, mononucleosis, meningitis, appendicitis, and scarlet fever were investigated, separately, and as cumulative infectious disease score. Multilevel adjusted linear regression analysis on the association between subjects' CIMT average and infectious diseases score was performed, stratifying by sex.", 'Youth (mean age 14.8yrs; 53% female) reported on average 1.3 of the listed infectious diseases; 22% boys and 15% girls reported 3 infectious diseases (p=0.136). Two-thirds were vaccinated according to recommendations (boys 56%, girls 61.5%, p=0.567). Sex-stratified analyses yielded significantly increased CIMT in boys with 3 infectious diseases vs. none (0.046mm, 95%CI 0.024; 0.068). In girls, the effect was of same direction but statistically non-significant (0.011mm, 95%CI-0.015; 0.036).
Answer: The SAPALDIA Youth study complements current evidence on infectious origins of atherosclerosis in adults. The larger effects observed in boys may relate to a higher vulnerability of the vasculature and/or to infectious pathogens. Our data are suggestive of an early impact of childhood infectious diseases on vascular health.
Are infectious diseases associated with carotid intima media thickness in adolescence?

Context: The use of sedation allows medical procedures to be performed outside the operating room while ensuring patient comfort and a controlled environment to increase the yield of the procedure. There is concern about a higher risk of adverse events with use of sedation in patients with obstructive sleep apnea.', 'We aimed to determine if the presence of obstructive sleep apnea increased the risk of hospitalization and/or health care use after patients received moderate conscious sedation for an elective, ambulatory colonoscopy.', 'We conducted a retrospective case-control database and chart review study. We compared hospital admissions, intensive care unit (ICU) admissions, and emergency room visits at 24 hours, 7 days, and 30 days in patients with obstructive sleep apnea (n=3,860) and without obstructive sleep apnea (n=2,374) who had undergone an elective, ambulatory colonoscopy with sedation.', 'We found no significant differences in hospital admissions, ICU admissions, or emergency room visits between the two groups at any time point within the 30 days following the procedures. In a sensitivity analysis in which we compared 827 individuals with polysomnographically confirmed sleep apnea with control subjects, there was still no difference in hospital admissions, ICU admissions, or emergency room visits in the 30 days after receiving sedation for the procedure. Outcomes were not different in individuals with various severities of obstructive sleep apnea.
Answer: The presence of obstructive sleep apnea was not associated with increased early hospital admissions, ICU admissions, or emergency room visits after colonoscopy with sedation.
