Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

[Q]: Biomarkers predictive of recovery from acute kidney injury (AKI) after liver transplantation (LT) could enhance decision algorithms regarding the need for liver-kidney transplantation or renal sparing regimens. Multianalyte plasma/urine kidney injury protein panels were performed immediately before and 1 month post-LT in an initial test group divided by reversible pre-LT AKI (rAKI = post-LT renal recovery) versus no AKI (nAKI). This was followed by a larger validation set that included an additional group: irreversible pre-LT AKI (iAKI = no post-LT renal recovery). In the test group (n = 16), six pre-LT plasma (not urine) kidney injury proteins (osteopontin [OPN], neutrophil gelatinase-associated lipocalin, cystatin C, trefoil factor 3, tissue inhibitor of metalloproteinase [TIMP]-1, and β-2-microglobulin) were higher in rAKI versus nAKI (P < 0.05) and returned to normal values with renal recovery post-LT. In the validation set (n = 46), a number of proteins were significantly higher in both rAKI and iAKI versus nAKI. However, only pre-LT plasma OPN (P = 0.009) and TIMP-1 (P = 0.019) levels were significantly higher in rAKI versus iAKI. Logistic regression modeling was used to correlate the probability of post-LT rAKI, factoring in both pre-LT protein markers and clinical variables. A combined model including elevated OPN and TIMP-1 levels, age <57, and absence of diabetes had the highest area under the curve of 0.82, compared to protein-only and clinical variable-only models.

[Q]: Recently, it has been shown that exposure to welding fumes containing both zinc and copper leads to asymptomatic systemic inflammation in humans as shown by an increase of blood C-reactive protein. In the present study, it was investigated which metal is responsible for this effect.', 'Fifteen healthy male subjects were exposed under controlled conditions to welding fumes containing either zinc, or copper, or copper and zinc.', 'For each exposure blood C-reactive protein increased.

[Q]: Both solid and hollow visceral abdominal injuries have been associated with the use of seat belts in children involved in motor vehicle crashes. The relationship between the types of restraint used and the pattern of abdominal injury is unknown.', "A probability sample of restrained children involved in crashes was enrolled in an ongoing crash surveillance system (1998 through 2002) linking insurance claims data to telephone survey and crash investigation data. Significant abdominal injuries were considered when the Abbreviated Injury Scale (AIS) score was > or =2 and were defined as hollow visceral (HV; intestine, bladder), or solid visceral (liver, spleen, pancreas, kidney). Restraint type was categorized as optimal restraint (OR) or suboptimal restraint (S-OR) based on the child's age and size.", 'For the 33 months of review, interviews were obtained for 13,558 restrained children aged 0 to 15 years, of which, 56% were OR (n = 7,591) and 44% were S-OR (n = 5,967). A significant abdominal injury was recorded in 78 children. A hollow visceral injury was recorded in 38 (9 OR and 29 S-OR), and a solid visceral injury in 32 (18 OR and 14 S-OR). Both hollow and solid visceral injuries were present in 8 children (2 OR and 6 S-OR). Suboptimally restrained children had a higher risk for hollow visceral injury when compared with optimally restrained children (Odds Ratio, 4.14 [95% Confidence Interval 1.33 to 13.22, P <.01]).
