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.

Q: Apical potassium channels regulate ion transport in airway epithelial cells and influence air surface liquid (ASL) hydration and mucociliary clearance (MCC). We sought to identify whether genetic variation within genes encoding airway potassium channels is associated with chronic rhinosinusitis (CRS).', "Single nucleotide polymorphism (SNP) genotypes for selected potassium channels were derived from data generated on the Illumnia HumanHap550 BeadChip or Illumina Human610-Quad BeadChip for 828 unrelated individuals diagnosed with CRS and 5,083 unrelated healthy controls from the Children's Hospital of Philadelphia (CHOP). Statistical analysis was performed with set-based tests using PLINK, and corrected for multiple testing.", 'Set-based case control analysis revealed the gene KCNMA1 was associated with CRS in our Caucasian subset of the cohort (598 CRS cases and 3,489 controls; p\u200a=\u200a0.022, based on 10,000 permutations). In addition there was borderline evidence that the gene KCNQ5 (p\u200a=\u200a0.0704) was associated with the trait in our African American subset of the cohort (230 CRS cases and 1,594 controls). In addition to the top significant SNPs rs2917454 and rs6907229, imputation analysis uncovered additional genetic variants in KCNMA1 and in KCNQ5 that were associated with CRS.

Q: More than 90% of anal condyloma is attributed to nonhigh risk strains of human papillomavirus (HPV), thus patients with anal condyloma do not necessarily undergo HPV serotyping unless they are immunocompromised (IC). We hypothesized that IC patients with anal condyloma have a higher risk of high-risk HPV and dysplasia than nonimmunocompromised (NIC) patients.', 'We performed a retrospective chart review of patients who underwent surgical treatment by a single surgeon for anal condyloma from 1/2000 to 1/2012. HPV serotyping was performed on all patient samples. We compared incidence of high-risk HPV and dysplasia in condyloma specimens from IC and NIC patients.', 'High-risk HPV was identified in 14 specimens with serotypes 16, 18, 31, 33, 51, 52, and 67. Twenty-two cases (18.3%) had dysplasia. Invasive carcinoma was identified in one IC patient. The prevalence of dysplasia or high-risk HPV was not significantly different between IC and NIC groups. High-risk HPV was a significant independent predictor of dysplasia (odds ratio [OR] = 5.2; 95% CI = 1.24-21.62). Immune status, however, was not a significant predictor of high-risk HPV (OR = 1.11; 95% CI = 0.16-5.12) nor dysplasia (OR = 0.27; 95% CI = 0.037-1.17).

Q: The use of fetal growth charts assumes that the optimal size at birth is at the 50(th) birth-weight centile, but interaction between maternal constraints on fetal growth and the risks associated with small and large fetal size at birth may indicate that this assumption is not valid for perinatal mortality rates. The objective of this study was to investigate the distribution and timing (antenatal, intrapartum or neonatal) of perinatal mortality and morbidity in relation to birth weight and gestational age at delivery.', "Data from over 1 million births occurring at 28-43\u2009weeks' gestation from singleton pregnancies without congenital abnormalities in the period from 2002 to 2008 were collected from The Netherlands Perinatal Registry. The distribution of perinatal mortality according to birth-weight centile and gestational age at delivery was studied.", "In the 1\u2009170\u2009534 pregnancies studied, there were 5075 (0.43%) perinatal deaths. The highest perinatal mortality occurred in those with a birth weight below the 2.3(rd) centile (25.4/1000 births) and the lowest mortality was in those with birth weights between the 80(th) and 84(th) centiles (2.4/1000 births), according to routinely used growth charts. Antepartum deaths were lowest in those with birth weight between the 90(th) and 95(th) centiles. Data were almost identical when the analysis was restricted to infants born at ≥\u200937\u2009weeks' gestation.
