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.

[EX Q]: Cerebral pressure passivity is common in sick premature infants and may predispose to germinal matrix/intraventricular hemorrhage (GM/IVH), a lesion with potentially serious consequences. We studied the association between the magnitude of cerebral pressure passivity and GM/IVH.', "We enrolled infants <32 weeks' gestational age with indwelling mean arterial pressure (MAP) monitoring and excluded infants with known congenital syndromes or antenatal brain injury. We recorded continuous MAP and cerebral near-infrared spectroscopy hemoglobin difference (HbD) signals at 2 Hz for up to 12 hours/day and up to 5 days. Coherence and transfer function analysis between MAP and HbD signals was performed in 3 frequency bands (0.05-0.25, 0.25-0.5, and 0.5-1.0 Hz). Using MAP-HbD gain and clinical variables (including chorioamnionitis, Apgar scores, gestational age, birth weight, neonatal sepsis, and Score for Neonatal Acute Physiology II), we built a logistic regression model that best predicts cranial ultrasound abnormalities.", 'In 88 infants (median gestational age: 26 weeks [range 23-30 weeks]), early cranial ultrasound showed GM/IVH in 31 (37%) and parenchymal echodensities in 10 (12%) infants; late cranial ultrasound showed parenchymal abnormalities in 19 (30%) infants. Low-frequency MAP-HbD gain (highest quartile mean) was significantly associated with early GM/IVH but not other ultrasound findings. The most parsimonious model associated with early GM/IVH included only gestational age and MAP-HbD gain.

[EX Q]: Prognosis of severe coronary artery disease with no indication of percutaneous coronary intervention or coronary artery bypass grafting remains poor. We have recently demonstrated that shock wave therapy effectively induces neovascularization and improves myocardial ischemia in a porcine model in vivo.', 'With permission from the Ethical Committee of our Institute, we treated nine patients with end-stage coronary artery disease with no indication of percutaneous coronary intervention or coronary artery bypass grafting (55-82 years old, five men and four women) with our cardiac shock wave therapy (200 shots/spot at 0.09 mJ/mm for 20-40 spots, 3 times a week/series). We followed-up the patients at 1, 3, 6, and 12 months after the therapy to examine the amelioration of myocardial ischemia. When needed, shock wave therapy was performed up to three series at 0, and 1, 3 or 6 months.', 'The cardiac shock wave therapy improved symptoms (Canadian Cardiovascular Society functional class score, from 2.7+/-0.2 to 1.8+/-0.2, P<0.01) and reduced nitroglycerin use (from 5.4+/-2.5 to 0.3+/-0.3/week, P<0.05). The treatment also improved myocardial perfusion as assessed by dipyridamole stress thallium scintigraphy (severity score, 25.2+/-7.2% improvement, P<0.05; extent score, 23.3+/-9.0% improvement, P=0.10; washout rate, 20+/-3 to 34+/-3, P<0.05). Myocardial perfusion was improved only in the ischemic area treated with the therapy. These beneficial effects persisted for 12 months. No procedural complications or adverse effects were noted.

[EX Q]: To investigate the association between early menarche (menarche age < 12 years) and Type 2 diabetes mellitus in young and middle-aged Korean women.', 'We analysed data for 4657 women aged 20-50 years from the Fourth Korea National Health and Nutrition Examination Survey (KNHANES IV) (2007-2009).', 'The prevalence of Type 2 diabetes was 2.8%. Women with early menarche had a higher prevalence of impaired fasting glucose than did women with later menarche (age ≥ 12 years) in the 20-30 age group (7.4% vs. 3.0%), and a higher prevalence of diabetes in the 30-40 (6.3% vs. 1.7%) and 40-50 (18.5% vs. 4.4%) age groups. The odds ratio (OR) of Type 2 diabetes in women with early menarche was 3.61 [95% confidence interval (CI), 1.90-6.88] after adjusting for age. In multivariate regression, the OR of Type 2 diabetes decreased to 2.52 (95% CI, 1.29-4.94) after further adjusting for BMI. However, the OR decreased to 2.04 (95% CI, 0.95-4.39) without significance after adjusting for HOMA-IR.
