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]: Patients with chronic heart failure (CHF) have multiple abnormalities of autonomic regulation that have been associated to their high mortality rate. Heart rate recovery immediately after exercise is an index of parasympathetic activity, but its prognostic role in CHF patients has not been determined yet.', 'Ninety-two stable CHF patients (83M/9F, mean age: 51+/-12 years) performed an incremental symptom-limited cardiopulmonary exercise testing. Measurements included peak O2 uptake (VO2p), ventilatory response to exercise (VE/VCO2 slope), the first-degree slope of VO2 for the 1st minute of recovery (VO2/t-slope), heart rate recovery [(HRR1, bpm): HR difference from peak to 1 min after exercise] and chronotropic response to exercise [%chronotropic reserve (CR, %)=(peak HR-resting HR/220-age-resting HR)x100]. Left ventricular ejection fraction (LVEF, %) was also measured by radionuclide ventriculography.', 'Fatal events occurred in 24 patients (26%) during 21+/-6 months of follow-up. HRR1 was lower in non-survivors (11.4+/-6.4 vs. 20.4+/-8.1; p<0.001). All cause-mortality rate was 65% in patients with HRR1<or=12 bpm versus 11% in patients with HRR1>12 bpm (log-rank: 32.6; p<0.001). By multivariate survival analysis, HRR1 resulted as an independent predictor of mortality (chi2=19.2; odds ratio: 0.87; p<0.001) after adjustment for LVEF, VO2p, VE/VCO2 slope, CR and VO2/t-slope. In a subgroup of patients with intermediate exercise capacity (VO2p: 10-18, ml/kg/min), HRR1 was a strong predictor of mortality (chi2: 14.3; odds ratio: 0.8; p<0.001).

[Q]: Immunosuppressant agents modulate the activity of the immune system and control adipose tissue inflammatory responses associated with obesity. Controlling adipose tissue inflammation represents an interesting option for inhibiting the low-grade inflammatory state in obese subjects and for preventing obesity-associated pathologies. In this work, we assessed the effects of thalidomide on the inflammatory response in adipose tissue as well as on systemic inflammatory marker expression in the well-established high-fat diet-induced obesity mouse model.', 'Swiss male mice were fed a high-fat diet (60% kcal from fat) for 12 weeks and received thalidomide for the last 10 days (100 mg.kg-1). Adipokine levels were measured in serum and adipose tissue by EIA and real-time quantitative PCR, respectively. Adipose tissue infiltrating macrophages were identified by immunohistochemistry and western blot analysis of F4/80 marker expression. Other inflammatory markers, such as c-Jun N-terminal kinase (JNK) phosphorylation and monocyte chemoattractant protein-1 (MCP-1) production, were also evaluated by western blot analysis. In vitro assays using 3T3-L1 adipocytes were also conducted to evaluated adipokine release.', 'In obese mice, thalidomide administration induced a reduction in adiposity accompanied by a reduction of tumor necrosis factor- (TNF-), leptin and MCP-1 adipose tissue production, macrophage infiltration and JNK activation. TNF- and leptin serum levels were also reduced by thalidomide treatment in obese mice. In vitro, the release of basal TNF- and lipopolysaccharide (LPS)-induced MCP-1 was inhibited in 3T3-L1 cells.

[Q]: Poor ventilation at day care centres (DCCs) was already reported, although its effects on attending children are not clear. This study aimed to evaluate the association between wheezing in children and indoor CO2 (a ventilation surrogate marker) in DCC and to identify behaviours and building characteristics potentially related to CO2. In phase I, 45 DCCs from Lisbon and Oporto (Portugal) were selected through a proportional stratified random sampling. In phase II, 3months later, 19 DCCs were further reassessed after cluster analysis for the greatest difference comparison. In both phases, children's respiratory health was assessed by ISAAC-derived questionnaires. Indoor CO2 concentrations and building characteristics of the DCC were evaluated in both phases, using complementary methods. Mixed effect models were used to analyze the data. In phase I, which included 3,186 children (mean age 3.11.5years), indoor CO2 concentration in the DCC rooms was associated with reported wheezing in the past 12months (27.5%) (adjusted odds ratio (OR) for each increase of 200ppm 1.04, 95% CI 1:01 to 1:07). In phase II, the association in the subsample of 1,196 children seen in 19 out of the initial 45 DCCs was not significant (adjusted OR 1.02, 95% CI 0.96 to 1.08). Indoor CO2 concentration was inversely associated with the practices of opening windows and internal doors and with higher wind velocity. A positive trend was observed between CO2 and prevalence of reported asthma (4.7%).
