TASK DEFINITION: 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.
PROBLEM: Context: We hypothesized that self-reported pad use per day (PPD) after pubovaginal sling (PVS) correlated with postoperative quality of life (QOL) scores.', 'Two hundred fifteen women completed the incontinence impact questionnaire 7 (IIQ-7) and urogenital distress inventory 6 (UDI-6) before PVS and during follow-up. Starting 3 days before a visit, women recorded the number of protective urinary pad changes per day. Analysis of variance and Pearson correlation tests were used to determine if women reporting zero, one, or greater than or equal to two urinary pads per day after PVS had significantly different changes in baseline QOL scores.', 'Over a mean 8.5 months follow-up after PVS, 131, 56, and 28 women reported zero, one, and greater than or equal to two pad changes/day. Each pad group showed progressively less improvement from baseline IIQ-7 and UDI-6 scores after PVS. Change in IIQ-7 and UDI-6 scores negatively correlated with PPD (p < 0.0001).
Answer: Self-reported PPD after PVS reflects patient perception of urinary-specific QOL.

SOLUTION: Does self-reported pad use per day reflect patient quality of life after pubovaginal sling surgery?

PROBLEM: Context: Despite recent advances in preoperative diagnostic imaging and operative techniques, biliary variation of the donor still remains a challenge in the procurement of graft. The supraportal right bile duct (BD) variant including presentation as trifurcation is a potential trap for injuring the remnant bile duct of donor.', 'Before living/related-donor liver transplantation (LRLT), cholangiogram with magnetic resonance images of each donor was performed as a routine. After exploration of the donor before hilar dissection, intraoperative chloangiography (IOC) was routinely performed. Among the supraportal right bile duct variants, if the preoperative cholangiography showed a suspected trifurcation of the bile duct, we then performed 3 sessions of IOC during liver graft procurement, including prior to hilar dissection, before the division of bile ducts and after the division. We reviewed the cholangiogram and the postoperative laboratory data of a consecutive series of 25 donors of LRLT.', 'There was no division injury of the remnant bile duct of all of the donors.
Answer: Repeated IOC is suggested as a routine for variants of supraportal right bile ducts especially trifurcation pattern in graft procurement to avoid the injury of donor remnant bile ducts.

SOLUTION: Is repeated introperative cholangiography helpful for donor safety in the procurement of right liver graft with supraportal right bile duct variants in living-donor liver transplantation?

PROBLEM: Context: To ascertain whether inoculation of lipopolysaccharide (LPS) into the mouse cochlea might induce enhancement of DNA binding activity of NK-kappa B and to establish a positive model of NF-kappa B activation in the cochlea.', 'Two groups of CBA mice were transtympanically injected either with 10 micrograms of LPS or an equal volume of saline. The nuclear proteins of the cochlea were extracted, quantitated and bound with 32P-radiolabeled oligonucleotide probe for NF-kappa B. The bound and free probes were separated by electrophoresis on a 4.5% native polyacrylamide gel. Supershift assays were carried out using the antibodies against NF-kappa B subunit P65 and P50.', 'The radiolabeled probe bound differently to nuclear extracts from the LPS-treated and the saline-treated mouse cochleae, showing that LPS inoculation significantly increased NF-kappa B binding activity. Supershift analysis demonstrated that the enhancement of DNA binding activity was related to both P65 and P50 subunits.
Answer: LPS could induce NF-kappa B activation in the cochlea. Moreover, this study implies that tissues from LPS-inoculated cochlea might serve as a useful positive control in the study on activation of NF-kappa B in cochlea.

SOLUTION:
Does [ Lipopolysaccharide enhance DNA binding activity of nuclear factor-kappa B in the mouse cochlea ]?
