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]: Deep erythema and inflammation after re-epithelialization of superficial wounds is a sign of scar formation. Corticosteroids may prevent scarring by suppression of inflammation and fibroblast activity. Tretinoin may increase the efficacy of corticosteroids in this setting.', 'To evaluate the efficacy of corticosteroids plus tretinoin for prevention of scars after superficial wounds.', 'In a retrospective study of patients with superficial partial thickness thermal skin burn, we compared the patients who received clobetasol plus tretinoin after re-epithelialization with patients who did not receive any medication. Clobetasol propionate 0.05% ointment was used twice daily with overnight occlusive dressing in conjunction with twice weekly topical tretinoin 0.05% cream.', 'Among 43 patients who had light pink or no erythema after re-epithelialization and consequently did not receive clobetasol\u2009+\u2009tretinoin, no scar was developed. Among patients who had deep erythema after re-epithelialization, rate of scar formation was significantly higher in 14 patients who did not receive clobetasol\u2009+\u2009tretinoin than in 21 patients who received clobetasol\u2009+\u2009tretinoin (64% and 19%, respectively; p\u2009=\u20090.01).

[Q]: The treatment of choice for aortic valve insufficiency due to root dilatation has become root replacement with aortic valve sparing. However, root replacement with a synthetic graft may result in altered valve stresses. The purpose of this study was to compare the stress/strain patterns in the spared aortic valve in different root replacement procedures by means of finite element modeling.', 'Our finite element model of the normal human root and valve was modified to simulate and evaluate three surgical techniques: (1) "cylindrical" graft sutured below the valve at the anulus, (2) "tailored" graft sutured just above the valve, and (3) "pseudosinus" graft, tailored and sutured below the valve at the anulus. Simulated diastolic pressures were applied, and stresses and strains were calculated for the valve, root, and graft. Leaflet coaptation was also quantified.', 'All three root replacement models demonstrated significantly altered leaflet stress patterns as compared with normal patterns. The cylindrical model showed the greatest increases in stress (16%-173%) and strain (10%-98%), followed by the tailored model (stress +10%-157%, strain +9%-36%). The pseudosinus model showed the smallest increase in stress (9%-28%) and strain (2%-31%), and leaflet coaptation was closest to normal.

[Q]: With advances in medicine, the subjective assessment of patients on hemodialysis regarding their quality of life (QOL) is gaining importance. Clinicians cannot rely solely on objective markers, such as the rates of complications and mortality, when evaluating responses to dialysis. In clinical settings, laboratory values are used as measures of patients' health. However, the relationship between clinical laboratory values and QOL has not been elucidated yet. Therefore, the present study aimed to define the relationship of laboratory values and patient attributes to the QOL of outpatients on hemodialysis in order to obtain basic data for reevaluating nursing support for patients on hemodialysis in the future.", 'The participants were 44 outpatients receiving hemodialysis at Hospital B. The QOL was surveyed using a self-administered questionnaire, the Kidney Disease Quality of Life Short Form. The following patient attributes and laboratory values were taken from the medical records: age; sex; primary disease; number of years on hemodialysis; complications; number of hours of hemodialysis per session; percentage weight gain; cardiothoracic ratio; blood pressure; hematocrit; and the serum levels of albumin, potassium, phosphorus, and calcium.', 'The serum potassium level significantly affected mental health, social functioning, symptoms, and the effect of kidney disease, with the 3.5-5.0 mEq/L target range group scoring higher than the > or =5.1 mEq/L group.
