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.

Although moderate (conscious) sedation is intended during elective gastrointestinal endoscopy, unintended levels of deep sedation occur. The aims of this study were to prospectively evaluate the incidence and risk factors of deep sedation during elective endoscopy with meperidine and midazolam intended to maintain a level of moderate sedation.', "Eighty American Society of Anesthesiology class 1-2, outpatients presenting for elective esophagogastroduodenoscopy (EGD), colonoscopy, endoscopic retrograde cholangiopancreatography (ERCP), and endoscopic ultrasonography (EUS) were offered enrollment. Intravenous meperidine and midazolam were administered according to a standardized protocol. Hemodynamic parameters and levels of sedation were assessed and recorded by a single observer at 3-min intervals. The Modified Observer's Assessment of Alertness/Sedation (MOAA/S) scale (ranging 1-5) is a subjective sedation assessment scale used to assess sedation levels. Occurrence of deep sedation, defined by MOAA/S 1-2, was recorded. Univariable and multivariable analyses were used to assess predictors of deep sedation.", 'Deep sedation occurred in 54/80 (68%) patients for a total of 204/785 (26%) of total sedation assessments. The percentage of deep sedation episodes of all sedation-level observations by procedure was 26% for EGD, 11% for colonoscopy, 35% for ERCP, and 29% for EUS. Deep sedation occurred at least once in 60% of EGD, 45% of colonoscopy, 85% of ERCP, and 80% of EUS. Multivariable analysis showed that only ERCP and EUS were independent risk factors of deep sedation.

Advanced heart failure (HF) is associated with increased morbidity and mortality; traditionally used prognostic factors often fail to predict the outcome. Increased red blood cell distribution width (RDW) has recently been recognized as an important unfavorable prognostic factor in HF, independent of anemia; however, the role of RDW in patients with advanced HF has not yet been investigated.', 'Eighty consecutive patients with stage D heart failure, recently hospitalized for HF decompensation, were enrolled. A Cox proportional-hazard model was used to determine whether RDW was independently associated with outcome.', 'At study entry, ejection fraction (EF), pulmonary capillary wedge pressure (PCWP), hemoglobin (Hb) and RDW were 25 ± 8.6%, 27.5 ± 8 mmHg, 12.5 ± 1.9 mg/dL and 18 ± 3.5% (normal <14.5%) respectively. At 6 months, 44 patients (55%) had died. In this patient population, EF (p=0.45), PCWP (p=0.106), age (p=0.54), albumin (0.678), iron (p=0.37), creatinine (p=0.432), iron deficiency defined by bone marrow aspiration (p=0.37), bilirubin (p=0.422), peak VO2 (p=0.057) and Hb (p=0.95) were not significant predictors of a worse outcome. However, RDW was a significant marker for adverse prognosis (p=0.007, HR: 1.14, CI: 1.04-1.24) and retained its prognostic significance even when corrected for Hb values (HR: 1.15, CI: 1.05-1.27, p=0.003).

Performance status [Eastern Cooperative Oncology Group (ECOG)] is a physician-assigned score indicating a patient's fitness for treatment. Functional assessment of cancer therapy-esophagus (FACT-E) is a patient-reported, health-related quality-of-life (HRQOL) instrument containing an oesophageal cancer subscale (ECS). Our objective was to assess the discriminative ability of pretreatment FACT-E and ECS when compared with performance status in predicting survival in patients with Stage II-III oesophageal cancer.", 'Patient data from four prospective studies were pooled together. These four studies included oesophageal patients who received chemoradiation either as neoadjuvant therapy or as definitive therapy. Three separate Cox regressions were performed considering FACT-E, ECS and ECOG as the main predictors, respectively. Receiver-operating characteristics analyses were performed.', 'Of the 120 curative intent patients, 39.8% (n = 51), 58.6% (n = 75) and 1.6% (n = 2) had ECOG 0, 1 and 2, respectively. On Cox regression analysis, pretreatment FACT-E (P = 0.04) and ECS (P = 0.004) but not ECOG (P = 0.27) were independently associated with overall survival. ECOG could not discriminate between survivors and non-survivors (P = 0.28) with an area under the curve (AUC) of 0.56 [95% confidence interval (CI): 0.45-0.66], whereas FACT-E (P = 0.02) and ECS (P < 0.001) were discriminative with AUC = 0.63 (95% CI: 0.52-0.73) and AUC = 0.69 (95% CI: 0.60-0.79), respectively.
