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: In short-gut rats, we showed marked abnormalities in plasma lipid fatty acids using parenteral nutrition (PN) with lipid vs sham surgery rats. This suggests that either sensing or metabolism of parenteral lipid is abnormal in malabsorption. The goal of this study was to determine fatty acid profiles in skeletal muscle and liver in short-gut rats treated with PN compared with sham rats.', 'Sprague-Dawley rats underwent laparotomy and massive small bowel resection (or sham surgery). Rats (n = 32, 16 sham, 16 short gut) were randomly assigned to PN with lipid or fat-free PN. After 5 days, weight loss was similar in all groups, and mixed hindlimb skeletal muscle and liver were biopsied.', 'We found marked differences between liver and skeletal muscle. In livers of short-gut animals, 22:4omega6, 22:5omega6, and 22:6omega3 were higher (all p < .05) than in sham. In skeletal muscle, short gut had no effect on fatty acid profiles. In liver, fat-free PN led to significant increases in 20:3omega6, 22:4omega6, 22:5omega6, 20:3omega9, 20:5omega3, 22:6omega3, and triene/tetraene ratio (all p < .05) compared with feeding PN with lipid, irrespective of short gut. In muscle, levels of the distal long-chain fatty acid metabolites and triene/tetraene ratio were minimally affected by nutrition. Serum glucose and insulin concentrations were similar in all 4 groups.

Q: Because of greater recognition and improved imaging capabilities, intraductal papillary mucinous neoplasms (IPMNs) are being diagnosed with increasing frequency. IPMNs of the main pancreatic duct cause symptoms and lead to pancreatitis. Side-branch (SB) IPMNs are thought to cause symptoms less frequently, and their association with pancreatitis is not well defined.', 'Our purpose was to ascertain whether an association exists between SB-IPMN and pancreatitis.', 'Single-center, retrospective study.', 'Academic medical center.', 'A total of 305 patients underwent EUS examinations between October 2002 and October 2006 for pancreatic cystic lesions.', 'The main outcome measure was the frequency of acute or chronic pancreatitis that was not procedurally related.', 'Thirty-two patients had SB-IPMNs, and 11 (34%) had pancreatitis. Three patients reported a single episode, and 8 patients reported having recurrent episodes of pancreatitis. Overall, 17 (53%) patients had symptoms possibly attributable to SB-IPMN. Female sex (73% vs 38%) and multiple pancreatic lesions (54% vs 24%) were more commonly seen in those with pancreatitis, but were not statistically significant factors. Larger cyst size or cyst fluid marker levels did not appear associated with pancreatitis occurrence. EUS-FNA demonstrated communication with the pancreatic duct in 94% and thick, mucinous fluid in 84%.

Q: The aim of this study was to investigate the rate, longitudinal improvement, and risk factors of sleep disturbance after 4 common orthopaedic traumatic conditions.', 'The functional status of 1095 patients was prospectively assessed using validated questionnaires for patients with acute proximal humerus (n = 111), distal radius (n = 440), tibial plateau (n = 109), and ankle fractures (n = 435). Patient reported sleep difficulty was compared with the overall functional and emotional status of each patient at 3, 6, and 12 months after treatment.', 'Sleep difficulty at 3-month follow-up was reported in 41% of patients with proximal humerus fracture, 25% of patients with distal radius fracture, 36% of patients with tibial plateau, and 19% of patients with ankle fracture. By 12-month follow-up, less than 20% of patients with all fracture types reported sleep difficulty. At 12-month follow-up, the SF-36 Mental Health category for patients with distal radius fractures (P = 0.001) and the Short Musculoskeletal Function Assessment Emotional category for patients with tibial plateau fractures (P = 0.024) and ankle fractures (P ≤ 0.001) were independent predictors of poor sleep, whereas the respective functional status categories were not.
