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.

Weight loss and malnutrition are poorly tolerated by geriatric patients, and pancreaticoduodenectomy (PD) can result in chronic malabsorption and weight loss. We sought to determine how preoperative severe nutritional risk (SNR), as defined by the American College of Surgeons National Surgical Quality Improvement Program/American Geriatric Society Best Practice Guidelines, affects long-term survival after PD for benign disease among geriatric and nongeriatric patients.', 'All patients undergoing PD for nonmalignant conditions at a single center between 1995 and 2013 were followed for survival, excluding patients who died within 90 days of surgery. Survival of geriatric (age 65 years) and nongeriatric (age <65 years) patients with and without SNR was compared using Kaplan Meier methods. Cox regression was performed.', 'There were 320 patients who underwent PD for benign disease. Over the course of the study, the proportion of geriatric patients undergoing PD for benign conditions increased from 25% to 46%. In addition to being older, geriatric patients undergoing PD for benign disease were significantly more likely to have coronary artery disease (CAD) and hypertension. Geriatric patients with preoperative SNR had significantly decreased long-term survival after PD for benign disease (p < 0.001), with roughly 1 in 3 patients dead at 5 years compared with 1 in 14 patients without SNR. Survival was not significantly different among nongeriatric patients with and without SNR. In geriatric patients, age, CAD, and SNR were significantly associated with decreased survival on both univariate and multivariate analysis.

We aimed to investigate structural abnormalities in first-episode remitted geriatric depression (RGD) with optimized voxel-based morphometry (VBM) in closely matched patients and healthy control subjects and examine the relationship of performances on neuropsychological tests with regional gray matter volumes.', 'Nineteen subjects with first-episode RGD and 16 well-matched healthy control subjects were recruited for this study, and neuropsychological tests and magnetic resonance imaging were conducted on the subjects. The differences in regional gray matter volume were determined between these two groups by optimized VBM.', 'The volumes of right superior frontal cortex, left postcentral cortex, and right middle temporal gyrus were significantly smaller in patients with RGD relative to healthy control subjects. However, patients with RGD had larger left cingulate gyrus volume compared with healthy control subjects. There was a significant negative correlation between left cingulate gyrus volume and Rey Auditory Verbal Learning Test delayed recall raw score in patients with RGD.

Ex Input:
To evaluate pain behavior and structural damage in mice subjected to either meniscal transection or removal.', 'Mice (10/group) were subjected to transection of the medial collateral and anterior cruciate ligaments (ACLT/MCLT) followed by either transection (meniscotomy) or removal (meniscectomy) of the medial meniscus. A control group was subjected only to transection of the ligaments. Pain was assessed using the electronic pressure-meter paw test. Cell influx, measured in joint exudates, and joint histopathology were assessed after 49 days. Four other groups subjected to meniscotomy received indomethacin, the inducible nitric oxide synthase (iNOS) inhibitor 1400W, morphine or the vehicles.', 'Both meniscotomy and meniscectomy groups displayed persistent and significant increase in pain behavior as compared to controls, being significantly more severe in the former. Cell influx was more intense in the meniscotomy as compared to the meniscectomy group. Structural damage at the tibia, but not at the femur, was also more severe in the meniscotomy group. Indomethacin and 1400W partially but significantly reduced pain whereas morphine abrogated pain behavior in meniscotomized mice.
