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.

Example Input: Transient tachypnea of the newborn (TTN) is a benign disorder with a variable clinical course that often leads to hospitalization. The aim of this study was to assess and validate the relationship between the serum cystatin C level and symptom duration in infants with TTN.', 'Forty newborns presenting with TTN and who had undergone serum cystatin C (Cys C) tests on the first day of admission to the Kyung Hee University Hospital (Seoul, Korea) from 2009 to 2013 were included. The serum Cys C level, creatinine (Cr) level, estimated glomerular filtration rate (eGFR), and tachypnea duration were correlated retrospectively.', 'The median gestation period was 37.8\xa0±\xa03.8 weeks and the mean birth weight was 3.2\xa0±\xa00.4\xa0kg. Tachypnea duration was 3.3\xa0±\xa02.0 days. Serum Cys C and Cr levels were 1.7\xa0±\xa00.2\xa0mg/L and 0.8\xa0±\xa01.2\xa0mg/dL, respectively. Tachypnea duration was significantly positively correlated with the serum levels of Cys C and significantly negatively correlated with Cys C-based eGFR (p\xa0=\xa00.016), but was not significantly correlated with the serum Cr level or Cr-based eGFR. When tachypnea duration was compared between infants with Cys C level <1.6\xa0mg/L (n\xa0=\xa015; Group A) and infants with Cys C level\xa0≥\xa01.6\xa0mg/L (n\xa0=\xa025; Group B), the symptom duration was significantly shorter in Group A infants (p\xa0=\xa00.011).
Example Output: Does decreased Cystatin C-Estimated Glomerular Filtration Rate be Correlated with Prolonged Hospital Stay in Transient Tachypnea of Newborn Infants?

Example Input: The purpose of this study was to determine whether four types of professionalism deficiencies in medical students identified during a first-year course on doctor-patient relationships might predict poor performance in third-year clerkships.', 'Preceptors identified students who had deficiencies in interviewing patients: extreme shyness, poor process skills, paternalism, or a negative attitude toward interviewing. Deficient students were matched by academic ability to a control group. Performance on third-year clerkships was compared.', 'Students with paternalistic behavior or negative attitudes had significantly lower third-year grades.
Example Output: Do professionalism deficiencies in a first-quarter doctor-patient relationship course predict poor clinical performance in medical school?

Example Input: Inactivating mutations in the Forkhead Box transcription factor F1 (FOXF1) gene locus are frequently found in patients with alveolar capillary dysplasia with misalignment of pulmonary veins, a lethal congenital disorder, which is characterized by severe abnormalities in the respiratory, cardiovascular, and gastrointestinal systems. In mice, haploinsufficiency of the Foxf1 gene causes alveolar capillary dysplasia and developmental defects in lung, intestinal, and gall bladder morphogenesis.', 'Although FOXF1 is expressed in multiple mesenchyme-derived cell types, cellular origins and molecular mechanisms of developmental abnormalities in FOXF1-deficient mice and patients with alveolar capillary dysplasia with misalignment of pulmonary veins remain uncharacterized because of lack of mouse models with cell-restricted inactivation of the Foxf1 gene. In the present study, the role of FOXF1 in endothelial cells was examined using a conditional knockout approach.', 'A novel mouse line harboring Foxf1-floxed alleles was generated by homologous recombination. Tie2-Cre and Pdgfb-CreER transgenes were used to delete Foxf1 from endothelial cells. FOXF1-deficient embryos exhibited embryonic lethality, growth retardation, polyhydramnios, cardiac ventricular hypoplasia, and vascular abnormalities in the lung, placenta, yolk sac, and retina. Deletion of FOXF1 from endothelial cells reduced endothelial proliferation, increased apoptosis, inhibited vascular endothelial growth factor signaling, and decreased expression of endothelial genes critical for vascular development, including vascular endothelial growth factor receptors Flt1 and Flk1, Pdgfb, Pecam1, CD34, integrin β3, ephrin B2, Tie2, and the noncoding RNA Fendrr. Chromatin immunoprecipitation assay demonstrated that Flt1, Flk1, Pdgfb, Pecam1, and Tie2 genes are direct transcriptional targets of FOXF1.
Example Output:
Is fOXF1 transcription factor required for formation of embryonic vasculature by regulating VEGF signaling in endothelial cells?
