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.

We investigated whether aprepitant, a neurokinin-1 antagonist, could decrease chemotherapy-induced nausea and vomiting (CINV) following cisplatin, when a conventional anti-emetic regimen had failed.', 'This was a prospective study (April 2011-April 2012) of patients with lung cancer, treated with cisplatin at the Beijing Cancer Hospital, and initially receiving granisetron, dexamethasone, and metoclopramide as anti-emetics. If patients experienced vomiting of grade 2 and required rescue anti-emetic medications during the first cycle, oral aprepitant was added in subsequent cycles (day 1: 125 mg; days 2-3: 80 mg once daily). Acute (day 1) and delayed (days 2-5) nausea and vomiting, use of rescue medications, and occurrence of adverse reactions were monitored after the start of chemotherapy.', 'Twenty-five of 132 patients (18.9 %) were administered aprepitant for secondary prophylaxis against emesis during the second cycle of chemotherapy. The incidences of acute and delayed nausea were 52 and 100 % in the first cycle, but 8 and 72 % in the second cycle. The incidences of acute and delayed vomiting were 20 and 100 % in the first cycle, but 0 and 36 % in the second cycle. No patients required rescue medications or intravenous rehydration during the second cycle. Aprepitant was not associated with additional adverse events.

The aim of this study is to determine the consequences of delayed presentation of anorectal malformations and emphasize the causes of delayed diagnosis of these malformations.', 'We retrospectively reviewed 54 neonatal patients with a diagnosis of anorectal malformations. Group 1 consisted of 35 patients diagnosed within the first 48h of life and Group 2 included 19 patients diagnosed after 48h of life.', 'Obstructive symptoms at the time of diagnosis, overall complications and the mean postoperative hospitalization period in Group 2 were markedly higher than that of Group 1. A comprehensive neonatal examination within the first 48h of life was performed in 32 (91.4%) patients in Group 1 and 5 (26.3%) of the patients in Group 2 (p<0.001).

Decreases in mate and/or pollinator availability would be expected to affect the selective pressure on plant mating systems. An increase in self-fertilization may evolve to compensate for the negative effects of pollination failure. However, the benefit of selfing in variable pollination environments depends on the relative fitnesses of selfed and outcrossed progeny. We investigated the potential for selfing to provide reproductive assurance over the lifetime of a long-lived perennial species and its variation between plant patches of various sizes. Patch size is likely to affect mate and pollinator availabilities, thereby affecting pollination success and the rate of selfing. We estimated fruit and seed set, reproductive assurance, self-compatibility, the multilocus patch selfing rate and lifetime inbreeding depression in natural patches of Rhododendron ferrugineum (Ericaceae), a mass-flowering species characterized by considerable patch size variation (as estimated by the total number of inflorescences).', 'Open seed set declined linearly with increasing patch size, whereas pollinator-mediated seed set (emasculated flowers) was not significantly affected. Progeny array analysis indicated that the selfing rate declined with increasing patch size, consistent with greater reproductive assurance in small sparse patches than in large, dense patches. However, fruit set and adult fitness decreased with decreasing patch size, with an estimated mean lifetime inbreeding depression of 0.9 (obtained by comparing F values in adults and progenies).
