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: Some living kidney donors report lost income during recovery from surgery. Little is known about whether concern for living donor's lost income affects the decision to undergo donation evaluation and the willingness of transplant candidates to discuss living kidney donation (LKD) with others.", 'To examine whether transplant patients were told by potential donors about lost income concerns and whether patients chose not to discuss LKD with others due to lost income concerns.', "Kidney transplant patients (185 wait-listed candidates, 171 deceased donor recipients, and 100 live donor recipients) at 2 centers completed a questionnaire to assess whether concern about donor's lost income was a consideration in discussion about LKD with others.", 'One-third (32%) were told by a family member/friend that they were willing to donate but were concerned about potential lost income. The majority of those who expressed financial concern (64%) did not initiate donation evaluation. Many patients (42%) chose not to discuss living donation with a family member/friend due to concern about the impact of lost income on the donor. In the multivariable model, lower annual household income was the only statistically significant predictor of both having a potential donor expressing lost income concern and choosing not to talk to someone because of lost income concern.

SOLUTION: Does concern for Lost Income Following Donation deter Some Patients From Talking to Potential Living Donors?

PROBLEM: Elevated levels of B-type natriuretic peptide (BNP) are associated with adverse clinical outcomes in acute coronary syndrome (ACS), but several questions remain outstanding. Firstly, it has not yet been determined whether an additional BNP sample at 7 weeks post ACS would enhance risk prediction. Secondly, we assessed whether the prognostic potential of BNP in ACS could be explained by echocardiographic abnormalities such as left ventricular hypertrophy (LVH).', 'We measured bedside BNP levels in 443 consecutive patients presenting with ACS and at 7 weeks outpatient follow-up. Main outcome measure was either all-cause mortality, readmission with ACS, or congestive heart failure) at 10 months from presentation.', 'Of the 443 patients, 120 patients presented with ST-elevation myocardial infarction (27%). There were 90 cardiovascular (CV) events at 10 months. Adjusting for age, sex, hypertension, diabetes mellitus, smoking status, renal dysfunction, left ventricular ejection fraction, and echocardiographic LVH elevated near patient BNP levels (>80 pg/mL) were still associated with subsequent CV events when measured on admission (adjusted relative risk [RR] 2.63 [95% CI 1.34-5.19)] and also at 7 weeks post ACS (adjusted RR 4.12 [95% CI 1.58-10.72]). Patients with persistent BNP elevation at 7 weeks were also at an increased risk of CV events compared to those with an initial high BNP which then fell (unadjusted RR 4.04 [95% CI 1.24-13.15]).

SOLUTION: Does serial bedside B-type natriuretic peptide strongly predict prognosis in acute coronary syndrome independent of echocardiographic abnormalities?

PROBLEM: BRAT1 (BRCA1-associated ATM activator 1) interacts with both BRCA1, ATM and DNA-PKcs, and has been implicated in DNA damage responses. However, based on our previous results, it has been shown that BRAT1 may be involved in cell growth and apoptosis, besides DNA damage responses, implying that there are undiscovered functions for BRAT1.', 'Using RNA interference against human BRAT1, we generated stable BRAT1 knockdown cancer cell lines of U2OS, Hela, and MDA-MA-231. We tested cell growth properties and in vitro/in vivo tumorigenic potentials of BRAT1 knockdown cells compared to control cells. To test if loss of BRAT1 induces metabolic abnormalities, we examined the rate of glycolysis, ATP production, and PDH activity in both BRAT1 knockdown and control cells. The role of BRAT1 in growth signaling was determined by the activation of Akt/Erk, and SC79, Akt activator was used for validation.', 'By taking advantage of BRAT1 knockdown cancer cell lines, we found that loss of BRAT1 expression significantly decreases cell proliferation and tumorigenecity both in vitro and in vivo. Cell migration was also remarkably lowered when BRAT1 was depleted. Interestingly, glucose uptake and production of mitochondrial ROS (reactive oxygen species) are highly increased in BRAT1 knockdown HeLa cells. Furthermore, both basal and induced activity of Akt and Erk kinases were suppressed in these cells, implicating abnormality in signaling cascades for cellular growth. Consequently, treatment of BRAT1 knockdown cells with Akt activator can improve their proliferation and reduces mitochondrial ROS concentration.

SOLUTION:
Does bRAT1 deficiency cause increased glucose metabolism and mitochondrial malfunction?
