question:
To understand whether the relationship between young children's autonomic nervous system (ANS) responses predicted their BMI, or vice versa, the association between standardized BMI (zBMI) at 2, 3.5, and 5 years of age and ANS reactivity at 3.5-5 years of age, and whether zBMI predicts later ANS reactivity or whether early ANS reactivity predicts later zBMI, was studied.", "Low-income, primarily Latino children (n=112) were part of a larger cohort study of mothers recruited during early pregnancy. Study measures included maternal prenatal weight, children's health behaviors (i.e., time watching television, fast food consumption, and time playing outdoors), children's height and weight at 2, 3.5, and 5 years, and children's ANS reactivity at 3.5 and 5 years. ANS measures of sympathetic nervous system (i.e., pre-ejection period) and parasympathetic nervous system (i.e., respiratory sinus arrhythmia) activity were monitored during rest and four challenges. Reactivity was calculated as the difference between mean challenge response and rest. Structural equation models analyzed the relationship between children's zBMI at 2, 3.5, and 5 years and ANS reactivity at 3.5 and 5 years, adjusting for mother's BMI, children's behaviors, and changes in height.", 'There was no association between zBMI and ANS cross-sectionally. Children with high zBMI at 2 or 3.5 years or large zBMI increases from 2 to 3.5 years of age had decreased sympathetic activity at 5 years. Neither sympathetic nor parasympathetic reactivity at 3.5 years predicted later zBMI.
answer:
Does latino children 's body mass index at 2-3.5 years predict sympathetic nervous system activity at 5 years?


question:
Mucosal human papillomaviruses (HPV) are a major cause of cancers and papillomas of the anogenital and oropharyngeal tract. HPV-vaccination elicits neutralising antibodies in sera and cervicovaginal secretions and protects uninfected individuals from persistent anogenital infection and associated diseases caused by the vaccine-targeted HPV types. Whether immunisation can prevent oropharyngeal infection and diseases and whether neutralising antibodies represent the correlate of protection, is still unclear.', 'We determined IgG and neutralising antibodies against low-risk HPV6 and high-risk HPV16/18 in sera and oral fluids from healthy females (n=20) before and after quadrivalent HPV-vaccination and compared the results with non-vaccinated controls.', 'HPV-vaccination induced type-specific antibodies in sera and oral fluids of the vaccinees. Importantly, the antibodies in oral fluids were capable of neutralising HPV pseudovirions in vitro, indicating protection from infection. The increased neutralising antibody levels against HPV16/18 in sera and oral fluids post-vaccination correlated significantly within an individual.
answer:
Does human papillomavirus vaccination induce neutralising antibodies in oral mucosal fluids?


question:
Although many factors predictive of patient survival have been reported for lung cancer, no comparative studies have attempted to determine those that are most significant for practical medicine.', 'We conducted a retrospective review of 139 patients who underwent complete resection of adenocarcinomas less than 2 cm in diameter between 1993 and 2000 at the National Cancer Center Hospital (Tokyo, Japan). The MIB-1 labeling index (LI), immunohistochemical staining for carcinoembryonic antigen (CEA), p53, p27, epidermal growth factor receptor (EGFR), phosphorylated-EGFR (pEGFR), Cox-2, neuronatin, gammaH2AX, and thyroid transcription factor-1 (TTF-1), the prevalence of a micropapillary pattern, and the ratio of the bronchioloalveolar cell carcinoma (BAC) or lepidic growth (LG) component were determined, and their significance as prognostic factors for lung adenocarcinoma was compared.', 'Univariate analysis showed that lymph node metastasis (p-N status), BAC/LG component, vascular invasion (p-V status), MIB-1 LI, pEGFR, and CEA were prognostically significant (p-N status: p < 0.0001, BAC/LG: p = 0.0005, p-V status: 0.002, MIB-1 LI: p = 0.005, pEGFR: p = 0.024, and CEA: p = 0.049). Multivariate analysis showed that only p-N status (p = 0.013) was of prognostic significance. However, BAC/LG component (p = 0.051) was a more reliable prognostic factor than p-N status in mixed adenocarcinoma with a BAC/LG component.
answer:

Is bronchioloalveolar carcinoma ( lepidic growth ) component a more useful prognostic factor than lymph node metastasis?
