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.

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)

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.

Patients with missed colorectal cancer have been reported to be more likely to have colonic diverticulosis. Such an association could be due to either higher risk of neoplasia or difficulty examining the colon in patients with diverticulosis. The aim of this study was to determine whether colonic diverticula are associated with an increased risk for colonic neoplasia.', 'We analyzed data from a prospective study of patients undergoing screening colonoscopy that included detailed assessment of all colonic diverticula and colorectal polyps. We used logistic regression to estimate odds ratios and 95% confidence intervals while adjusting for confounding variables.', 'Our analyses included 624 participants. Of these, 216 (35%) had one or more colorectal adenomas. Diverticula on colonoscopy were not associated with an increased risk of adenomas (odds ratio (OR) 1.0, 95% confidence interval (CI) 0.7-1.4) or advanced adenomas (OR 0.8, 95% CI 0.4-1.5). Those with the greatest burden of diverticula (10 or more) did not have an increased risk of adenomas (OR 1.1, 95% CI 0.7-1.8) compared with no diverticula. Colonic diverticula were not associated with an increased risk of proximal (OR 1.0, 95% CI 0.6-1.6) or distal adenomas (OR 1.0, 95% CI 0.6-1.7).
