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.

Palliative sedation therapy (PST) is indicated for and used to control refractory symptoms in cancer patients undergoing palliative care. We aimed to evaluate whether PST has a detrimental effect on survival in terminally ill patients.', 'This multicenter, observational, prospective, nonrandomized population-based study evaluated overall survival in two cohorts of hospice patients, one submitted to palliative sedation (A) and the other managed as per routine hospice practice (B). Cohorts were matched for age class, gender, reason for hospice admission, and Karnofsky performance status.', 'Of the 518 patients enrolled, 267 formed cohort A and 251 cohort B. In total, 25.1% of patients admitted to the participating hospices received PST. Mean and median duration of sedation was 4 (standard deviation 6.0) and 2 days (range 0-43), respectively. Median survival of arm A was 12 days [90% confidence interval (CI) 10-14], while that of arm B was 9 days (90% CI 8-10) (log rank = 0.95, P = 0.330) (unadjusted hazard ratio = 0.92, 90% CI 0.80-1.06).

A common variant of the IGF-I gene has been shown to be associated with cardiovascular disease in adulthood. The objective of this study was to examine whether this variant of the IGF-I gene is associated with blood pressure and left heart dimensions in early childhood.', 'This study was embedded in the Generation R Study, a population-based prospective cohort study from foetal life onwards. IGF-I promoter region was genotyped in DNA obtained from cord blood. Blood pressure (systolic and diastolic) and echocardiography (left ventricular mass, left atrial diameter and aortic root diameter) measurements were performed at the age of 2 years. Analyses were performed in 538 subjects.', 'Eight alleles of the IGF-I promoter region were identified. In total, 43% of the subjects were homozygous for the 192 bp allele (wild type), 46% were heterozygous and 11% were non-carriers. Significantly lower systolic and diastolic blood pressures were found in non-carrier subjects (difference compared with homozygous subjects: -4.4 (95% confidence interval (CI) -7.8 to -1.1) mmHg and -3.5 (95% CI: -6.9 to -0.1) mm respectively). No significant differences were found for left heart dimensions at the age of 2 years. No association was found when we used a previously proposed alternative classification of the IGF-I gene.

Sensitisation with Aspergillus fumigatus (Af) is known to be associated with severe allergic lung inflammation, but the mechanism remains to be clarified. Phosphoinositide 3-kinase (PI3K)-δ and endoplasmic reticulum (ER) stress are suggested to be involved in steroid-resistant lung inflammation. We aimed to elucidate the role of PI3K-δ and its relationship with ER stress in fungus-induced allergic lung inflammation.', 'Using Af-exposed in vivo and in vitro experimental systems, we examined whether PI3K-δ regulates ER stress, thereby contributing to steroid resistance in fungus-induced allergic lung inflammation. Moreover, we checked expression of an ER stress marker in lung tissues isolated from patients with allergic bronchopulmonary aspergillosis.', 'Af-exposed mice showed that ER stress markers, unfolded protein response (UPR)-related proteins, phosphorylated Akt, generation of mitochondrial reactive oxygen species (mtROS), eosinophilic allergic inflammation, and airway hyperresponsiveness (AHR) were increased in the lung. Similarly, glucose-regulated protein 78 was increased in lung tissues of patients with ABPA. A PI3K-δ inhibitor reduced Af-induced increases in ER stress markers, UPR-related proteins, allergic inflammation and AHR in mice. However, dexamethasone failed to reduce Af-induced allergic inflammation, AHR and elevation of ER stress. Administration of an ER stress inhibitor or a mtROS scavenger improved Af-induced allergic inflammation. The PI3K-δ inhibitor reduced Af-induced mtROS generation and the mtROS scavenger ameliorated ER stress. In primary cultured tracheal epithelial cells, Af-induced ER stress was inhibited by blockade of PI3K-δ.
