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.

Example Input: Virus-induced wheezing episodes in infancy often precede the development of asthma. Whether infections with specific viral pathogens confer differential future asthma risk is incompletely understood.', 'To define the relationship between specific viral illnesses and early childhood asthma development.', 'A total of 259 children were followed prospectively from birth to 6 years of age. The etiology and timing of specific viral wheezing respiratory illnesses during early childhood were assessed using nasal lavage, culture, and multiplex reverse transcriptase-polymerase chain reaction. The relationships of these virus-specific wheezing illnesses and other risk factors to the development of asthma were analyzed.', 'Viral etiologies were identified in 90% of wheezing illnesses. From birth to age 3 years, wheezing with respiratory syncytial virus (RSV) (odds ratio [OR], 2.6), rhinovirus (RV) (OR, 9.8), or both RV and RSV (OR , 10) was associated with increased asthma risk at age 6 years. In Year 1, both RV wheezing (OR, 2.8) and aeroallergen sensitization (OR, 3.6) independently increased asthma risk at age 6 years. By age 3 years, wheezing with RV (OR, 25.6) was more strongly associated with asthma at age 6 years than aeroallergen sensitization (OR, 3.4). Nearly 90% (26 of 30) of children who wheezed with RV in Year 3 had asthma at 6 years of age.

Example Input: Removal of a humeral component during revision shoulder arthroplasty can be difficult. If the component cannot be extracted from above, an alternative approach may compromise bone integrity. Two potential solutions are a humeral window and a longitudinal split. This review was performed to determine complications and outcomes associated with these osteotomies during revision arthroplasty.', 'We reviewed records of 427 patients undergoing revision shoulder arthroplasty, identifying those requiring a window or longitudinal split. Outcomes were intraoperative and postoperative complications, rate of healing, and security of implant fixation.', 'Twenty-six patients underwent creation of a window. Six intraoperative fractures were documented: 5 in greater tuberosity and 1 in humeral shaft. At radiographic follow-up, 23 of 26 windows healed; 2 patients had limited follow-up, and 1 did not have follow-up at our institution. Nineteen patients underwent longitudinal osteotomy. One had intraoperative fracture in greater tuberosity. At radiographic follow-up, 17 of 19 longitudinal splits healed; 1 had limited radiographic follow-up, and 1 did not have follow-up at our institution. Three patients underwent formation of both window and longitudinal osteotomy. At radiographic follow-up, all shoulders healed, and there were no intraoperative or postoperative fractures or malunions.

Example Input: To examine whether adrenomedullin, a novel vasoactive peptide produced by the placenta, participates in the uteroplacental hemodynamic alterations in intrauterine growth restriction, we studied the correlation between adrenomedullin levels and fetoplacental blood flow.', 'Maternal and umbilical blood samples were collected in pregnancies complicated by intrauterine growth restriction with abnormal umbilical artery Doppler findings and in control pregnancies. Adrenomedullin levels were measured by means of a specific radioimmunoassay, and flow velocimetry waveforms were recorded from uterine, umbilical, and fetal middle cerebral arteries.', 'Mean adrenomedullin values in umbilical plasma were higher (P <.05) in patients with intrauterine growth restriction (63.7 +/- 34.2 pg/mL; n = 16) than in control subjects (38.1 +/- 14.8 pg/mL; n = 16). A significant correlation was found between maternal adrenomedullin levels and umbilical artery pulsatility index. Moreover, fetal adrenomedullin concentrations correlated negatively with middle cerebral artery pulsatility index and positively with umbilical artery pulsatility index/middle cerebral artery pulsatility index ratio.
