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.

Input: Consider Input: To report 4 patients with Avellino corneal dystrophy (ACD) who were treated with 0.02% mitomycin C (MMC) during phototherapeutic keratectomy (PTK).', 'ACD was confirmed by polymorphism of the exon region in the BIGH3 gene using polymerase chain reaction followed by DNA sequencing analysis. Three patients with recurrent ACD and 1 patient with primary ACD underwent PTK. Intraoperative 0.02% MMC was applied topically with a soaked microsponge.', 'There was no recurrence of ACD in the heterozygotes, but there were recurrences with best-corrected visual acuity of 20/30 in the 2 homozygotes.

Input: Consider Input: ADAMTS 13, sP-Selectin and HSP27 have been investigated as potential prognostic markers in patients with hemorrhagic shock.', "This study was part of a double-blind, randomized, parallel-group, controlled trial and included seventeen trauma patients presented to ED with severe hemorrhagic. The sera for testing were collected from these patients at the time of admission. Investigators and laboratory personnel performing testing were blinded to the patients' identity and clinical course.", 'The prognostic value of ADAMTS13, sP-Selectin, and HSP27 was compared to prognostic value of systolic blood pressure (SBP), base deficit estimation (BD), heart rate (HR), shock index (SI) and tissue oxygen saturation (StO2) by constructing the receiver operation characteristics (ROC). The area under the curve (AUC) of the ROC for HSP27 (0.92) was greater than for SBP (0.45), BD (0.89), HR (0.61), SI (0.45) and StO2 (0.46). AUC for sP-Selectin (0.86) and for ADAMTS13 antigen (0.74) were comparable with BD one, but greater than for the rest of currently used tests.

Input: Consider Input: Androgen receptor (AR) plays an important role in male breast cancer (MBC). Additionally, endocrine therapy is the most important treatment in oestrogen receptor (ER)-positive advanced breast cancer. This study was aimed to investigate the role of AR in MBC treatment and prognosis and to analyse the relationship between AR and the effect of tamoxifen treatment in MBC patients.', 'AR protein levels and other tumour characteristics (e.g. expression of ER (ESR1), PR (PGR), AR, HER2 (ERBB2) and Ki-67 (MKI67)) in breast cancer tissue from 102 MBC patients were determined using immunohistochemical analysis. Additionally, the relationship between AR status and clinicopathological features was analysed using the χ(2)-test. Association with survival was initially analysed using the Kaplan-Meier method and the log-rank test, and Cox regression analysis was used to adjust for other prognostic indicators.', 'High expression of AR was not correlated with T-stage, histological grade, HER2 status and the status of other sex hormone receptors, but was associated with lymph node metastases (P=0.032). AR-positive patients showed significantly shorter 5-year overall survival (OS) rates (P=0.045) and 5-year disease-free survival (DFS) rates (P=0.026) than AR-negative patients. By contrast, for patients who received tamoxifen therapy, AR-negative patients showed a higher clinical benefit rate than AR-positive patients (P=0.025). Additionally, the median TTP and OS were significantly different (P=0.02 for TTP; P=0.029 for OS).
