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.

Input: Consider Input: To determine whether full-scale simulation (SIM) is superior to interactive problem-based learning (PBL) for teaching medical students acute care assessment and management skills.', 'Randomized controlled trial.', 'Simulation center at a U.S. medical school.', 'Thirty-one fourth-year medical students in a week-long acute care course.', 'After institutional review board approval and informed consent, eligible students were randomized to either the SIM or PBL group. On day 1, all subjects underwent a simulator-based initial assessment designed to evaluate their critical care skills. Two blinded investigators assessed each student using a standardized checklist. Subsequently, the PBL group learned about dyspnea in a standard PBL format. The SIM group learned about dyspnea using the simulator. To equalize simulator education time, the PBL group learned about acute abdominal pain on the simulator, whereas the SIM group used the PBL format. On day 5, each student was tested on a unique dyspnea scenario.', "Mean initial assessment and final assessment checklist scores and their change for the SIM and PBL groups were compared using the Student's t-test. A p < .05 was considered significant. The SIM and PBL groups had similar mean (PBL 0.44, SIM 0.47, p = .64) initial assessment scores (earned score divided by maximum score) and were deemed equivalent. The SIM group performed better than the PBL group on the final assessment (mean, PBL 0.53, SIM 0.72, p < .0001). When each student's change in score (percent correct on final assessment minus percent correct on the initial assessment) was compared, SIM group students performed better (mean improvement, SIM 25 percentage points vs. PBL 8 percentage points, p < .04)

Input: Consider Input: Secreted phospholipases A(2) (sPLA(2)s) are released in plasma and other biologic fluids of patients with inflammatory, autoimmune, and allergic diseases.', 'We sought to evaluate sPLA(2) activity in the bronchoalveolar lavage fluid (BALF) of asthmatic patients and to examine the expression and release of sPLA(2)s from primary human lung mast cells (HLMCs).', 'sPLA(2) activity was measured in BALF and supernatants of either unstimulated or anti-IgE-activated HLMCs as hydrolysis of oleic acid from radiolabeled Escherichia coli membranes. Expression of sPLA(2)s was examined by using RT-PCR. The release of cysteinyl leukotriene (LT) C(4) was measured by means of enzyme immunoassay.', 'Phospholipase A(2) (PLA(2)) activity was higher in the BALF of asthmatic patients than in the control group. BALF PLA(2) activity was blocked by the sPLA(2) inhibitors dithiothreitol and Me-Indoxam but not by the cytosolic PLA(2) inhibitor AZ-1. HLMCs spontaneously released a PLA(2) activity that was increased on stimulation with anti-IgE. This PLA(2) activity was blocked by dithiothreitol and Me-Indoxam but not by AZ-1. HLMCs constitutively express mRNA for group IB, IIA, IID, IIE, IIF, III, V, X, XIIA, and XIIB sPLA(2)s. Anti-IgE did not modify the expression of sPLA(2)s. The cell-impermeable inhibitor Me-Indoxam significantly reduced (up to 40%) the production of LTC(4) from anti-IgE-stimulated HLMCs.

Input: Consider Input: Hepatitis B s antigen (HBsAg) seroclearance is regarded as the optimal virological end-point.', 'To investigate the dynamic changes in serum cytokine levels around the time of HBsAg seroclearance.', 'This was a case-control study. Consecutive patients with chronic hepatitis B (CHB) who lost HBsAg were matched with those remained positive for HBsAg with same age, gender, HBeAg status and presence of cirrhosis in 1:2 ratio. Relevant serum cytokines [interleukin (IL)-2, IL-3, IL-4, IL-7, IL-9, IL-10, IL-12, IL-15, IL-21 interferon-γ, tumour necrosis factor-α (TNF-α), granulocyte macrophage colony-stimulating factor (GM-CSF) and interferon-inducible protein 10 (IP-10)] were assayed at the time (Year 0) and 3 years before (Year -3) HBsAg seroclearance.', 'Seventy-one and 142 CHB patients who did and did not achieve HBsAg seroclearance were included. Mean age was 48 ± 11 years; 76% were male, 20% had positive HBeAg, 99 (46%) patients received anti-viral therapy, and mean baseline HBV DNA was 3.78 ± 2.28 log IU/mL vs. 4.36 ± 2.13 log IU/mL respectively (P = 0.05). In those who achieved HBsAg seroclearance, serum IL-15 and GM-CSF levels decreased significantly from Year -3 to Year 0 (P = 0.017 and 0.05 respectively). When compared to controls, only serum IP-10 level was significantly lower at Year 0 than at Year -3 in patients with HBsAg seroclearance. Lower serum IP-10 level at Year 0 was the only factor associated with HBsAg seroclearance. There was no correlation between serum IP-10 and HBsAg levels around the time of HBsAg seroclearance.
