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.

Q: Context: To examine the concentration of C-reactive protein (CRP) in relation to gestational weeks during pregnancy among Chinese women.', 'From a randomized control trial of prenatal supplementation with folic acid, iron-folic acid, and multiple micronutrients in China, we examined 834 pregnant women with CRP measured initially between 5 and 20 weeks and at follow-up between 28 and 32 weeks gestation. We calculated and plotted CRP geometric means by gestational weeks. The same analysis was repeated for women who had normal pregnancies (624 women) by excluding women with stillbirth, preterm, small for gestational age, body mass index <18.5 kg/m(2) or >30 kg/m(2) at enrollment, and hypertension or anemia during pregnancy.', 'We observed a significant positive trend between log-transformed CRP and gestational age from 5 to 20 weeks and from 28 to 32 weeks both in the full sample and in the subset of women who had normal pregnancies. CRP geometric mean was 0.81 mg/l at 5-7 weeks of gestation, 2.85 mg/l at 19-20 weeks of gestation, and 3.89 mg/l at 32 weeks of gestation. A similar increasing trend in the CRP median or percentage of elevated CRP were also observed.
Answer: We concluded that CRP increased with gestational age among healthy Chinese women who delivered healthy infants. Am. J. Hum. Biol. 28:574-579, 2016. © 2016 Wiley Periodicals, Inc.

A: Does c-reactive protein increase with gestational age during pregnancy among Chinese women?

Q: Context: Hypertrophic cardiomyopathy (HCM) is associated with myocardial scarring and ventricular tachycardia (VT). Contrast-enhanced cardiac magnetic resonance imaging (CE-CMR) can quantify myocardial scar, and scar imaging has been documented in patients with HCM. We investigated the assessment of myocardial scar in HCM patients using CE-CMR, and its correlation with proven VT.', 'Twenty-five patients (mean age 54 +/- 8) with HCM who underwent CE-CMR were identified, and clinical data obtained from chart review. Parameters of LV function were calculated from cine imaging, and myocardial scar was assessed using delayed enhancement imaging following gadolinium administration.', 'Myocardial scar was detected in 16 (64%) patients with a mean mass 9 +/- 15 g. Scar was patchy, mid-myocardial and located in the basal anteroseptum, and RV insertion sites. Scar was seen in septal, apical and concentric variants of HCM. Scar mass correlated with both LV Mass (r2 = 0.74) and maximal LV wall thickness (r2 = 0.42). VT occurred in 32% of patients, and was associated with both increased scar mass and wall thickness compared to non-VT patients (21 +/- 22 g vs. 4 +/- 6 g, and 2.4 +/- 0.5 cm vs. 1.8 +/- 0.5 cm, p < 0.05). LV size and function were similar in patients with and without VT. A scar mass of >7 g predicted the presence of VT with a sensitivity of 75% and specificity 82%.
Answer: Myocardial scar imaged by CE-CMR is common in patients with HCM, and is predictive of VT. Scar is seen in all HCM variants, and is associated with maximal wall thickness. There may be a role for CE-CMR in improved risk stratification for individual patients with HCM.

A: Is myocardial scar detected by contrast-enhanced cardiac magnetic resonance imaging associated with ventricular tachycardia in hypertrophic cardiomyopathy patients?

Q: Context: The need for liver biopsy is increasing with the increasing availability of treatments for liver disease, in particular interferon. For this reason the procedure must be efficient and economical, as well as safe.', "Firstly to assess the safety of outpatient liver biopsy when performed with ultrasound guidance and the 'Biopty' gun. Secondly, to compare the cost of an outpatient and inpatient procedure.", "Two hundred and fifty consecutive liver biopsies performed over a two year period at St Vincent's Hospital, Melbourne were reviewed retrospectively. Indications, histological findings and complications were recorded.", 'Seventy per cent of the biopsies were performed as an outpatient procedure. There were no major complications. Four patients experienced prolonged pain post biopsy. The average cost for an outpatient biopsy was $351, the cost of an inpatient (overnight stay) was $690.
Answer: Outpatient liver biopsy is safe and cost effective, with minor complications in 1.6%. The routine use of ultrasound guidance and the Biopty gun is likely to contribute to these favourable results.

A:
Is outpatient liver biopsy using ultrasound guidance and the Biopty gun safe and cost effective?
