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.

Input: Consider Input: Chronic kidney disease (CKD) is associated with increased cardiovascular events. The relationships between the markers of inflammation and endothelial dysfunction were investigated both before and after living donor kidney transplantation.', 'Twenty-seven renal transplant patients were studied. Eleven patients (six male, five female) were on cyclosporine A, whereas 16 patients (nine male, seven female) were treated with tacrolimus based regimes. Twenty-seven subjects (12 males, 15 females) were studied as controls. Plasma adiponectin, high sensitive C reactive protein (hsCRP), Asymetric dimethyl arginine (ADMA) levels were studied before transplantation and on days 1, 3, 7, 14, and 28. The brachial artery flow mediated dilatation (FMD) was studied before transplantation and on the 28th day.', 'Serum hsCRP and ADMA levels decreased significantly from the first posttransplantation day on each measurement (P<0.001 for all) while the decrement of plasma adiponectin started in the third day (P<0.001 for all). The FMD was lower in the patients than the control group (P<0.001) and improved significantly in the 28th day of transplantation (P<0.001).

Output: Do endothelial functions improve with decrease in asymmetric dimethylarginine ( ADMA ) levels after renal transplantation?


Input: Consider Input: To understand whether the relationship between young children's autonomic nervous system (ANS) responses predicted their BMI, or vice versa, the association between standardized BMI (zBMI) at 2, 3.5, and 5 years of age and ANS reactivity at 3.5-5 years of age, and whether zBMI predicts later ANS reactivity or whether early ANS reactivity predicts later zBMI, was studied.", "Low-income, primarily Latino children (n=112) were part of a larger cohort study of mothers recruited during early pregnancy. Study measures included maternal prenatal weight, children's health behaviors (i.e., time watching television, fast food consumption, and time playing outdoors), children's height and weight at 2, 3.5, and 5 years, and children's ANS reactivity at 3.5 and 5 years. ANS measures of sympathetic nervous system (i.e., pre-ejection period) and parasympathetic nervous system (i.e., respiratory sinus arrhythmia) activity were monitored during rest and four challenges. Reactivity was calculated as the difference between mean challenge response and rest. Structural equation models analyzed the relationship between children's zBMI at 2, 3.5, and 5 years and ANS reactivity at 3.5 and 5 years, adjusting for mother's BMI, children's behaviors, and changes in height.", 'There was no association between zBMI and ANS cross-sectionally. Children with high zBMI at 2 or 3.5 years or large zBMI increases from 2 to 3.5 years of age had decreased sympathetic activity at 5 years. Neither sympathetic nor parasympathetic reactivity at 3.5 years predicted later zBMI.

Output: Does latino children 's body mass index at 2-3.5 years predict sympathetic nervous system activity at 5 years?


Input: Consider Input: Previous studies have proved the feasibility of performing a pancreaticoduodenectomy (Whipple operation) in patients with portal vein-superior mesenteric vein and hepatic artery invasion. We report our institutional experience with the use of a variety of vascular reconstructive methods during pancreatic resections for adenocarcinoma.', 'A retrospective review was performed identifying all patients undergoing a Whipple operation or total pancreatectomy procedure from January 2003 to December 2013. All venous (portal vein-superior mesenteric vein) and arterial (superior mesenteric artery-hepatic artery) reconstructions were extracted and reviewed to determine survival and perioperative complications.', 'During the 10-year study period, 270 Whipple and total pancreatectomy procedures were performed, of which 183 were for adenocarcinoma of the pancreas. Of the 183 operations, a total of 60 (32.8%) vascular reconstructions were found, 49 venous and 11 arterial. Venous reconstruction included 37 (61.7%) primary repairs, four (6.7%) reconstructions with CryoVein (CryoLife, Inc, Kennesaw, Ga), three (5.0%) repairs with autologous vein patch, three (5.0%) autologous saphenous reconstructions, and two (3.33%) portacaval shunts. In addition, there were 11 (18.3%) arterial reconstructions (seven hepatic artery and four superior mesenteric artery). The 1-year survival for all reconstructions was 71.1%, which is equivalent to T3 lesions that did not receive vascular reconstruction (70.11%), with a median survival time of 575.28 days and 12 patients still alive. Survival time was comparable with each type of venous reconstruction, averaging 528 days (11 of 49 patients still alive). There was a total thrombosis rate of seven of 60 (11.6%), all of which were portal vein thrombosis: three in the primary repair group and four delayed thromboses seen in primary repair, CryoVein repair, and vein patch repair. There was no thrombosis in any patients after arterial reconstruction.


Output: Does vascular reconstruction play an important role in the treatment of pancreatic adenocarcinoma?
