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.

Anti-Mullerian hormone (AMH) may have a role in disordered folliculogenesis in polycystic ovary syndrome (PCOS). Though there have been several investigations into circulating AMH levels in patients with PCOS, no previous studies have compared AMH concentrations in the follicular fluid of unstimulated ovaries in women with PCOS with that of normally ovulating women.', 'Follicular fluid was aspirated from 4-8-mm follicles of unstimulated ovaries during routine laparoscopy or laparotomy from women with anovulatory PCOS (n = 11) and those with regular ovulatory cycles (n = 8). Follicular AMH was compared in the two groups. Serum samples were analysed for AMH and endocrine profile.', 'Follicular fluid AMH levels were significantly higher (P < 0.0001) in women with anovulatory PCOS (median: 466.2 ng/ml) compared with normal-ovulatory controls (median: 78.0 ng/ml). Mean follicular fluid AMH levels in PCOS patients were 60 times higher than in the serum. Moreover, there was a significant correlation between the follicular fluid and serum concentrations of AMH in the PCOS group (r = 0.86; P = 0.007) but not in controls.

Several studies have reported that ventriculoperitoneal shunt insertion for treatment of normal-pressure hydrocephalus results in improvement of gait and, less frequently, improvement of cognition. We sought to identify the demographic factors associated with cognitive improvement after shunt insertion to improve assessment of prognosis for cognitive gains with treatment.', 'We report cognitive testing before and after ventriculoperitoneal shunt insertion in 36 patients with normal pressure hydrocephalus, who previously had improvement of any clinical symptom--gait, urinary incontinence, cognition--after a diagnostic trial of continuous cerebrospinal fluid drainage.

Recent research suggests that body vitamin D levels are decreased in coronary heart disease and diabetes, but it is unclear which cardiovascular risk factors are related to vitamin D status.', 'To examine the relation between vitamin D status and major cardiovascular risk factors.', 'Serum 25-hydroxyvitamin D3, a marker of recent sun exposure and vitamin D status, was measured in 390 New Zealand residents (95 Pacific Islanders, 74 Maori and 221 others mostly of European descent), who were part of a larger cross-sectional survey of a workforce (n = 5677) aged 40-64 years.', 'Serum 25-hydroxyvitamin D3 levels were significantly lower in Pacific Islanders (mean (SE) = 56 (3) nmol/L; p = 0.0001) and Maoris (68 (3) nmol/L; p = 0.036) compared with Europeans (75 (2) nmol/L) after adjusting for age, sex and time of year. Also adjusting for ethnic group, 25-hydroxyvitamin D3 was higher in people doing vigorous (aerobic) leisure physical activities (71 (2) nmol/L; p = 0.0066) and moderate (non-aerobic) activities (68 (3) nmol/L; p = 0.12) compared with those who were inactive (63 (2) nmol/L). However, 25-hydroxyvitamin D3 was unrelated to body mass index, serum lipids, blood pressure or cigarette smoking.
