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.

Non-shockable rhythms represent an increasing proportion of reported cases of out-of-hospital cardiac arrest but with an associated poor prognosis. In the present study, we investigated the effects of hydrogen inhalation on cardiac and neurological function after cardiopulmonary resuscitation and compared the therapeutic benefit with hypothermia in an asphyxial rat model of cardiac arrest.', 'Cardiopulmonary resuscitation was initiated after 5 min of untreated asphyxial cardiac arrest. Animals were randomly assigned to three experimental groups immediately after successful resuscitation: ventilation with 2% hydrogen/98% oxygen under normothermia (H2 inhalation), ventilation with 2% nitrogen/98% oxygen under normothermia (Control), and ventilation with 2% nitrogen/98% oxygen under hypothermia (TH). Mixed gas inhalation continued for 1 h while hypothermia continued for 2\u200ah. Animals were observed up to 96\u200ah for assessment of survival and neurologic recovery.', 'No statistical differences in baseline measurements were observed among groups and all the animals were successfully resuscitated. Serum cardiac troponin T and S100B measured during earlier post-resuscitation period were markedly reduced in both H2 inhalation and hypothermic groups. However, significantly better left ventricular ejection fraction, cardiac work, and neurological deficit score were observed in the H2 inhalation group. Ninety-six hours survival rate was significantly higher in the H2 inhalation group (75.0%), either compared with TH (45.8%) or compared with Control (33.3%). But there was no statistical difference between TH and Control.

Serrated lesions are an important contributor to colorectal cancer (CRC), notably in the proximal colon. Findings in the distal colorectum are markers of advanced proximal adenomatous neoplasia. However, it is not known whether they affect the odds of advanced proximal serrated lesions.', 'We performed a retrospective cross-sectional study of data from 1910 patients (59.3 ± 8.0 years, 53.8% female) who underwent an average-risk screening colonoscopy from August 2005 through April 2012 at Indiana University Hospital and an associated ambulatory surgery center. Colonoscopies were performed by an endoscopist with high rates of detection of adenomas and serrated polyps. Tissue samples of all serrated polyps (hyperplastic, sessile serrated adenoma/polyp [SSA/P], or traditional serrated adenoma) proximal to the sigmoid colon and serrated polyps >5 mm in the rectum or sigmoid colon were reviewed by a gastrointestinal pathologist and reclassified on the basis of World Health Organization criteria. Advanced serrated lesion (ASL) was defined as SSA/P with cytologic dysplasia, SSA/P ≥10 mm, or traditional serrated adenoma. Advanced conventional adenomatous neoplasia (ACN) was defined as tubular adenoma ≥10 mm, villous histology, high-grade dysplasia, or cancer. The prevalence of proximal ASL and ACN was calculated on the basis of distal colorectal findings. Multivariable logistic regression analysis was performed to determine the age-adjusted and sex-adjusted odds of advanced proximal adenomatous and serrated lesions. Secondary analyses were performed to examine the effect of variable ASL definitions.', 'Fifty-two patients (2.7%) had proximal ASL, and 99 (5.2%) had proximal ACN. Of the 52 patients with proximal ASL, 27 (52%) had no distal polyps. Of the 99 patients with proximal ACN, 40 (40%) had no distal polyps. Age and type of distal adenomas were significantly associated with proximal ACN. There were no significant associations between distal polyp type and proximal ASL. In secondary analyses, distal SSA/Ps (P\xa0= .008) but not distal hyperplastic polyps or conventional adenomas were associated with any proximal SSA/P.

Assessing acute myocardial infarction (MI) with respect to long-term survival is not easy. Authorities in the field suggest that inflammation predicts short-range (up to 17 months) coronary death. It is not known whether long-term survival is associated with the inflammatory response. In this study, we evaluate the relationships between survival for more than 8 years and inflammation, i.e., circulating interleukin-6 (IL-6) and neutrophil counts, in acute MI.', 'Patients with ST-segment elevation MIs (STEMI; n=33) and non-ST-segment MIs (non-STEMI; n=39) in 1996 were included in the study. All STEMI patients received thrombolytic therapy. Acute coronary angiography was not an option. Determination of IL-6 and neutrophils was carried out within 24 h after commencement of pain. The subjects were followed for more than 8 years (until December 31, 2005) using the national death registry. Inflammatory markers at the time of MI were compared with long-term survival (n=35).', 'At the time of acute MI, survivors for more than 8 years proved to have lower IL-6 (p<0.01) and decreased neutrophil counts (p<0.05). The differences remained (p<0.01 for both markers) when excluding deaths (n=11) occurring in 1996 and 1997. Subsequently, the subjects were divided into two equally sized groups, depending on their IL-6 values at the beginning of the study. As expected, a lower IL-6 was associated with a more favorable long-term prognosis (p<0.01).
