In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Ex Input:
Context: Readout-segmented echo planar imaging (rs-EPI) significantly reduces susceptibility artifacts in diffusion-weighted imaging (DWI) of the breast compared to single-shot EPI but is limited by longer scan times. To compensate for this, we tested a new simultaneous multi-slice (SMS) acquisition for accelerated rs-EPI.', 'After approval by the local ethics committee, eight healthy female volunteers (age, 38.9 ± 13.1 years) underwent breast MRI at 3T. Conventional as well as two-fold (2× SMS) and three-fold (3× SMS) slice-accelerated rs-EPI sequences were acquired at b-values of 50 and 800 s/mm(2). Two independent readers analyzed the apparent diffusion coefficient (ADC) in fibroglandular breast parenchyma. The signal-to-noise ratio (SNR) was estimated based on the subtraction method. ADC and SNR were compared between sequences by using the Friedman test.', 'The acquisition time was 4:21 min for conventional rs-EPI, 2:35 min for 2× SMS rs-EPI and 1:44 min for 3× SMS rs-EPI. ADC values were similar in all sequences (mean values 1.62 × 10(-3)mm(2)/s, p=0.99). Mean SNR was 27.7-29.6, and no significant differences were found among the sequences (p=0.83).\Question: Do simultaneous multi-slice readout-segmented echo planar imaging for accelerated diffusion-weighted imaging of the breast?

Ex Output:
SMS rs-EPI yields similar ADC values and SNR compared to conventional rs-EPI at markedly reduced scan time. Thus, SMS excitation increases the clinical applicability of rs-EPI for DWI of the breast.


Ex Input:
Context: Microalbuminuria and impaired endothelium-dependent vasodilation are both predictors for cardiac events in patients with type 2 diabetes. The aim of the study was to evaluate whether microalbuminuria correlated with coronary endothelium-dependent vasodilation.', 'We evaluated 84 patients (47 men, mean age 50.5 +/- 5.9 years) with type 2 diabetes for 9.4 +/- 3.4 years, without angiographic coronary stenosis and without major cardiovascular risk factors or other confounding factors, for endothelium investigation. Quantitative coronary angiography was used to assess coronary artery response to cold pressor testing, used to assess endothelium-dependent vasodilation, and to isosorbide dinitrate (endothelium-independent vasodilation).', 'Endothelium-dependent vasodilation differed in the patients with and without microalbuminuria (changes in coronary artery diameter during cold pressor testing: -15.0 +/- 1.9% vs. -10.2 +/- 1.3%, respectively, P < 0.05) and correlated with urinary albumin excretion rate (r = -0.39, P = 0.003), diastolic blood pressure (r = 0.29, P < 0.01), and left ventricular mass index (r = -0.24, P < 0.05). Independent predictors for endothelium-dependent vasodilation were urinary albumin excretion rate (beta -0.04 [95% CI -0.07 to -0.01], P < 0.005) and left ventricular mass index (-0.26 [-0.49 to -0.05], P < 0.05). Endothelium-independent vasodilation was similar in both groups.\Question: Is impaired coronary endothelium-dependent vasodilation associated with microalbuminuria in patients with type 2 diabetes and angiographically normal coronary arteries?

Ex Output:
Type 2 diabetic patients with microalbuminuria have a more severely impaired coronary endothelium-dependent vasodilation than those with normoalbuminuria. These data suggest a common pathophysiological process for both coronary vasomotor abnormalities and microalbuminuria.


Ex Input:
Context: The present meta-analysis aimed to investigate whether there is an association between SERPINE1 rs1799768 polymorphism and sepsis risk and mortality.', 'Published reports were searched in PubMed, PubMed Central, Gene, PubChem and Google Scholar. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were assessed in a random-effects model.', 'The results of the overall meta-analysis indicated that an increased sepsis risk was evidently associated with SERPINE1 rs1799768 polymorphism (OR = 1.30; 95% CI 1.08-1.56; p = 0.006). When studies were stratified by ethnicity, no significant association was observed between SERPINE1 rs1799768 polymorphism and sepsis risk in the Asian group. As for the Caucasian population, overall OR was 1.24 (95% CI 1.02-1.51; p = 0.03). The results of the overall meta-analysis indicated that an increased sepsis mortality risk was evidently associated with SERPINE1 rs1799768 polymorphism (OR = 1.73; 95% CI 1.31-2.28; p < 0.0001). When studies were stratified by ethnicity, significant association was observed between SERPINE1 rs1799768 polymorphism and sepsis risk mortality in the Asian group and the Caucasian population.\Question: Does sERPINE1 rs1799768 polymorphism contribute to sepsis risk and mortality?

Ex Output:

In conclusion, the meta-analysis suggests that there are significant associations between SERPINE1 rs1799768 polymorphism and risk of sepsis and sepsis mortality.
