TASK DEFINITION: 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.
PROBLEM: 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).

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

PROBLEM: The objective of this study was to compare health-related quality of life (HR-QoL), disability/work productivity, and health care utilization in a variety of medical disorders with and without comorbid major depressive disorder (MDD) in the general population.', 'Twelve-month MDD (Composite International Diagnostic Interview) diagnosis was determined among 4181 participants from a community sample. Medical diagnoses (respiratory, cardiovascular, allergic, endocrine/metabolic, gastrointestinal, and neurological diseases) were made after medical examination. HR-QoL was evaluated with the MOS-SF-36. Outpatient doctor visits and disability/work productivity were assessed by self-report.', 'Comorbid MDD was associated with a lower SF-36 mental summary score in all medical diagnoses and with a lower physical summary score in comorbid allergic and neurological disorders. The number of coexisting medical disorders was strongly related to lower physical and mental summary scores in cases without comorbid depression. The number of outpatient doctor visits increased by 42% when any of the medical disorders without comorbid MDD was present, and comorbid MDD was associated with a further 24-42% increase, depending on the medical disorder. Comorbid MDD was strongly associated with lower full-time working status (37.1% with MDD vs. 51.0% without MDD) and with a significant increase in disability days (45%) in the presence of any medical disorder.

SOLUTION: Do medical disorders affect health outcome and general functioning depending on comorbid major depression in the general population?

PROBLEM: The role of the adipokine, resistin in mediating increases in aortic stiffness is uncertain. We aimed to determine independent relations between circulating resistin concentrations and aortic pulse wave velocity (PWV) and wave reflection in a community-based sample with a high prevalence of untreated hypertension and obesity.', 'Plasma resistin, adiponectin, and C-reactive protein concentrations (ELISA); carotid-femoral (aortic) PWV and the aortic reflected wave index (applanation tonometry and SphygmoCor software) were determined in 683 randomly selected participants of African ancestry from SOWETO, South Africa who had never received antihypertensive therapy.', 'Resistin concentrations were not independently associated with office or 24-h (n\u200a=\u200a492) blood pressure (BP). In a stepwise regression model with BMI included in the model, age (P\u200a<\u200a0.0001), mean arterial pressure (P\u200a<\u200a0.0001), plasma resistin concentrations (P\u200a<\u200a0.005), female sex (P\u200a=\u200a0.01), and creatinine concentrations (P\u200a<\u200a0.01) contributed independently to variations in PWV. Independent relations between resistin concentrations and PWV persisted with further adjustments for C-reactive protein concentrations (P\u200a<\u200a0.005), and the homeostasis model of insulin resistance (P\u200a<\u200a0.02). Similar relations were noted with waist circumference rather than BMI in the model. Resistin concentrations were not independently associated with aortic reflected wave index or aortic BP.

SOLUTION:
Are circulating resistin concentrations independently associated with aortic pulse wave velocity in a community sample?
