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 the association of ethanol intoxication with hypoglycemia in ED patients.', 'Retrospective, laboratory log review of 953 consecutive patients who were evaluated for ethanol intoxication in an urban university hospital ED over a three-month period. Simultaneous serum glucose determination was carried out for each patient and associations between ethanol level and glucose were sought.', 'Glucose concentrations were unavailable for 16 patients (1.7%). Of the remaining patients, 584 patients had detectable ethanol concentrations (ethanol-positive), and 353 had no detectable ethanol (ethanol-negative). Ethanol concentrations (mean +/- SD) in the ethanol-positive group were 50.11 +/- 24.08 mmol/L (231 +/- 111 mg/dL), and glucose concentrations were 5.83 +/- 1.94 mmol/L (105 +/- 35 mg/dL). Hypoglycemia [glucose < 3.72 mmol/L (67 mg/dL)] was observed for five (0.9%) ethanol-positive patients. It was classified as mild-moderate [2.78-3.66 mmol/L (50-66 mg/dL)] for four patients (0.7%) and severe [< 2.78 mmol/L (50 mg/dL)] for one (0.2%). Ethanol concentrations ranged from 25.60 to 68.33 mmol/L (118 to 315 mg/dL). There was no correlation between ethanol and glucose concentrations in any subset of the ethanol-positive patients population. In the ethanol-positive group, patients who had several ethanol-positive visits (56 patients, mean 3.6 visits/patient) accounted for four of the five episodes of hypoglycemia, including the one episode of severe hypoglycemia. The frequency of hypoglycemia in repeat visitors (2.0%) was higher than that in the group of patients without repeat visits (0.2%). In the ethanol-negative group, there were four (1.1%) episodes of mild-moderate hypoglycemia and no severely hypoglycemic patients. Hypoglycemia was not more likely to occur among ethanol-positive patients than it was among ethanol-negative patients.

The treatment of choice for aortic valve insufficiency due to root dilatation has become root replacement with aortic valve sparing. However, root replacement with a synthetic graft may result in altered valve stresses. The purpose of this study was to compare the stress/strain patterns in the spared aortic valve in different root replacement procedures by means of finite element modeling.', 'Our finite element model of the normal human root and valve was modified to simulate and evaluate three surgical techniques: (1) "cylindrical" graft sutured below the valve at the anulus, (2) "tailored" graft sutured just above the valve, and (3) "pseudosinus" graft, tailored and sutured below the valve at the anulus. Simulated diastolic pressures were applied, and stresses and strains were calculated for the valve, root, and graft. Leaflet coaptation was also quantified.', 'All three root replacement models demonstrated significantly altered leaflet stress patterns as compared with normal patterns. The cylindrical model showed the greatest increases in stress (16%-173%) and strain (10%-98%), followed by the tailored model (stress +10%-157%, strain +9%-36%). The pseudosinus model showed the smallest increase in stress (9%-28%) and strain (2%-31%), and leaflet coaptation was closest to normal.

The purpose of this study was to examine the osteotomy gap filling rate with new bone after open wedge high tibial osteotomy (HTO) without bone graft and the effects of smoking, lateral hinge fracture, and early full weight bearing.', 'A prospective series (N\xa0= 70) of open wedge HTOs with the TomoFix plate (DePuy Synthes, Umkirch, Germany) was performed. Radiologic follow-up examinations took place postoperatively, after 6 and 12 weeks, and after 6, 12, and 18 months to measure osteotomy gap filling at each follow-up. Bone healing was compared in smokers versus nonsmokers who underwent open wedge HTOs with intact lateral hinges. Fractured lateral hinges were classified according to the Takeuchi classification and separately analyzed regarding bone healing. Patients were randomly assigned to undergo early (11 days) or standard (6 weeks) full-weight-bearing rehabilitation.', 'A delay in the osteotomy gap filling rate between smokers and nonsmokers could be observed at all follow-up periods, but differences were not significant. A fracture of the lateral hinge was found in 39% of the patients. A type I fracture was observed in 14% of patients, a type II fracture was observed in 13%, and a type III fracture was found in 6%. The highest increase in the osteotomy gap filling rate was observed between 12 weeks and 6 months after surgery in patients with intact lateral hinges. For patients with unstable type II fractures, the highest increase in the gap filling rate was delayed until 6 to 12 months. Early full weight bearing had no effect on the gap filling rate in any of the patient groups evaluated.
