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.

Example Input: Computed tomography (CT) is an imaging modality involving ionizing radiation. The presence of γ-H2AX foci after low to moderate ionizing radiation exposure has been demonstrated; however it is unknown whether very low ionizing radiation exposure doses from CT exams can induce γ-H2AX formation in vivo in young children.', 'To test whether very low ionizing radiation doses from CT exams can induce lymphocytic γ-H2AX foci (phosphorylated histones used as a marker of DNA damage) formation in vivo in young children.', 'Parents of participating children signed a consent form. Blood samples from three children (ages 3-21\xa0months) undergoing CT exams involving very low blood ionizing radiation exposure doses (blood doses of 0.22-1.22\xa0mGy) were collected immediately before and 1\xa0h post CT exams. Isolated lymphocytes were quantified for γ-H2AX foci by a technician blinded to the radiation status and dose of the patients. Paired t-tests and regression analyses were performed with significance levels set at P\u2009<\u20090.05.', 'We observed a dose-dependent increase in γ-H2AX foci post-CT exams (P\u2009=\u20090.046) among the three children. Ionizing radiation exposure doses led to a linear increase of foci per cell in post-CT samples (102% between lowest and highest dose).

Example Input: The appropriateness of vigorous fluid resuscitation to normal blood pressure following hemorrhage in uncontrolled bleeding has recently been questioned due to the possibility of dislodging clots and exacerbating hemorrhage. To develop a rational blood pressure target that maximizes the metabolic benefits of resuscitation without causing increased blood loss, it was first necessary to determine whether there is a reproducible mean arterial pressure (MAP) at which rebleeding occurs. The purpose of this study was to explore the relationship between the rate and time of resuscitation after injury and the rebleeding MAP in an uncontrolled hemorrhage model.', "Sixty-two anesthetized pigs were instrumented with catheters and splenectomized, and suction tubes were placed in the lateral peritoneal recesses to continuously capture shed blood. With the abdomen open, an aortotomy was made in the infrarenal aorta. At either 5, 15, or 30 minutes after the end of the initial hemorrhage, resuscitation with warmed lactated Ringer's solution was begun at either 100 or 300 mL/min. The rebleeding MAP was determined at the moment blood appeared in the suction tubes.", 'The average pressure at the rebleeding point for all animals was MAP = 64 +/- 2, Systolic = 94 +/- 3, and Diastolic = 45 +/- 2 mm Hg. The pressure at which rebleeding occurred in this aortotomy model was not affected by either time of resuscitation (5-30 min), nor was the rebleeding pressure affected by the rate (100 vs. 300 mL/min) of resuscitation.

Example Input: The prognosis of patients with severe aortic stenosis, low aortic gradient and preserved ejection fraction is controversial. Our study analyzed the prognosis of these patients and its relation to pressure gradient and aortic valve flow.', 'We performed a retrospective cohort study of 363 consecutive patients with severe aortic stenosis and preserved ejection fraction, divided into 4 groups, based on the presence of a systolic volume index greater or lower than 35 mL/m(2) and the presence of a mean aortic gradient greater or lower than 40 mmHg. Group I: normal flow, high gradient (n=169, 47%); group II: normal flow, low gradient (n=98, 27%); group III: low flow, high gradient (n=54, 15%), and group IV: low flow, low gradient (n=42, 12%). The primary endpoint was overall mortality.', 'Independent risk factors for mortality were age (hazard ratio=1.04; 95% confidence interval, 1.01-1.08) and atrial fibrillation (hazard ratio=2.21; 95% confidence interval, 1.24-3.94). Surgical treatment was associated with longer survival in all groups (hazard ratio=0.25; 95% confidence interval: 0.13-0.49). Mortality was higher in patients with low flow than in those with with normal flow (26.6% vs 13.6%; P=.004). The most favorable mean prognosis was found in group II (hazard ratio=0.4; 95% confidence interval, 0.2-0.9).
