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: Information about malaria risk factors at high altitudes is scanty. Understanding the risk factors that determine the risk of malaria transmission at high altitude villages is important to facilitate implementing sustainable malaria control and prevention programs.', 'An unmatched case control study was conducted among patients seeking treatment at health centers in high altitude areas. Either microscopy or rapid diagnostic tests were used to confirm the presence of plasmodium species. A generalized linear model was used to identify the predictors of malaria transmission in high altitude villages.', 'Males (AOR\u200a=\u200a3.11, 95%CI: 2.28, 4.23), and those who traveled away from the home in the previous month (AOR\u200a=\u200a2.01, 95% CI: 1.56, 2.58) were strongly associated with presence of malaria in high altitude villages. Other significant factors, including agriculture in occupation (AOR\u200a=\u200a1.41, 95% CI: 1.05, 1.93), plants used for fencing (AOR\u200a=\u200a1.70, 95% CI: 1.18, 2.52) and forests near the house (AOR\u200a=\u200a1.60, 95% CI: 1.15, 2.47), were found predictors for malaria in high altitude villages.

Input: Consider Input: To investigate the effect of the percentage of free prostate-specific antigen (%fPSA) on future prostate cancer risk.', 'We examined serum total PSA (tPSA) and %fPSA annually in a prostate cancer-screening cohort between July 2001 and June 2011. Men with tPSA >4.0 ng/mL or tPSA of 2.0-4.0 ng/mL with %fPSA ≤12% were screened as positive and were recommended to undergo a biopsy. The study population consisted of 6368 men, aged 40-79 years, who had tPSA ≤4.0 ng/mL at initial screening and who subsequently underwent 1 or more screenings. We calculated the cumulative risk and hazard ratio of prostate cancer stratified by the initial %fPSA groups as quartiles of prostate cancer patients.', 'During a median follow-up of 36 months, 119 men were diagnosed with prostate cancer. The lowest quartile of %fPSA (<13.3%) was associated with a 21.2-fold higher risk of having prostate cancer compared with the highest quartile (>22.2%). For the subset with an initial tPSA ≤1.0 ng/mL, all men diagnosed with cancer had an initial %fPSA ≤33.3% (median). For the subset with tPSA >1.0 ng/mL, men with %fPSA ≤23.0% (median) had significantly higher risk for cancer than those with %fPSA >23.0% (P <.0001). Of the 114 men with prostate cancer in whom pathologic findings were available, 79 (69.3%) had a Gleason score ≥3 + 4 = 7.

Input: Consider Input: Use of enriched environment (EE) housing has been shown to promote recovery from cerebral ischaemic injury but the underlying mechanisms of their beneficial effects remains unclear. Here we examined whether the beneficial effects of EE housing on ischaemia-induced neurodegeneration and cognitive impairment are associated with increased insulin-like growth factor-1 (IGF-1) signalling in the hippocampus.', 'Forty-two adult male Wistar rats were included in the study and received either ischaemia or sham surgery. Rats in each group were further randomized to either: EE or standard laboratory cage housing (control). Rats were placed in their assigned housing condition immediately after recovery from anaesthesia. Behavioural testing in the cued learning and discrimination learning tasks were conducted 2\u2009weeks after ischaemia. Rats were euthanized after behavioural testing and the hippocampus was analysed for IGF-1 level, IGF-1 receptor (IGF-1R) activation, protein kinase B (Akt) pathway activation, neurone loss and caspase 3 expression.', 'Our data showed that EE housing: (1) mitigated ischaemia-induced neuronal loss; (2) attenuated ischaemia-induced increase in caspase 3 immunoreactivity in the hippocampus; (3) ameliorated ischaemia-induced cognitive impairments; and (4) increased IGF-1R activation and signalling through the Akt pathway after ischaemic injury.
