Faecal occult blood (FOB) - based screening programmes for colorectal cancer detect about half of all cancers. Little is known about individual health behavioural characteristics which may be associated with screen-detected and interval cancers. Electronic linkage between the UK National Health Service Bowel Cancer Screening Programme (BCSP) in England, cancer registration and other national health records, and a large on-going UK cohort, the Million Women Study, provided data on 628,976 women screened using a guaiac-FOB test (gFOBt) between 2006 and 2012. Relative risks (RRs) and 95% confidence intervals (CIs) were estimated by logistic and Cox regression for associations between individual lifestyle factors and risk of colorectal tumours. Among screened women, 766 were diagnosed with screen-detected colorectal cancer registered within 2 years after a positive gFOBt result, and 749 with interval colorectal cancers registered within 2 years after a negative gFOBt result. Current smoking was significantly associated with risk of interval cancer (RR 1.64, 95%CI 1.35–1.99) but not with risk of screen-detected cancer (RR 1.03, 0.84–1.28), and was the only factor of eight examined to show a significant difference in risk between interval and screen-detected cancers (p for difference, 0.003). Compared to screen-detected cancers, interval cancers tended to be sited in the proximal colon or rectum, to be of non-adenocarcinoma morphology, and to be of higher stage.  相似文献

In this issue of the Hastings Center Report, James Sabin and his colleagues ask what responsibility investigators in a learning health organization have to patients when research—particularly research of which patients might be unaware—illuminates problematic aspects of the patients' care. Sabin and his colleagues were confronted by this question in the midst of designing a randomized controlled trial that sought to determine if an educational intervention targeted at patients with atrial fibrillation and their clinicians reduces underuse of oral anticoagulants. Worried about harm that might befall patients in the control group and fearing that they would be negligent bystanders if they knew these patients were at risk and did nothing, the investigators adopted a “workaround.” But the “workaround,” I suggest, was not a solution to the negligent bystander problem. Nor was it a solution to the problem as I would alternatively frame it—how to address instances of suboptimal patient care identified through research within learning health organizations.  相似文献

Persuasive messages can change people's thoughts, feelings, and actions, but these effects depend on how people think about and appraise the meaning of these messages. Drawing from research on the cognitive control of emotion, we used neuroimaging to investigate neural mechanisms underlying cognitive regulation of the affective and persuasive impact of advertisements communicating the risks of binge drinking, a significant public health problem. Using cognitive control to up‐regulate (vs. down‐regulate) responses to the ads increased: negative affect related to consequences of excessive drinking, perceived ad effectiveness, and ratings of ad self‐relevance made after a one‐hour delay. Neurally, these effects of cognitive control were mediated by goal‐congruent modulation of ventromedial prefrontal cortex and distributed brain patterns associated with negative emotion and subjective valuation. These findings suggest that people can leverage cognitive control resources to deliberately shape responses to persuasive appeals, and identify mechanisms of emotional reactivity and integrative valuation that underlie this ability. Specifically, brain valuation pattern expression mediated the effect of cognitive goals on perceived message self‐relevance, suggesting a role for the brain's valuation system in shaping responses to persuasive appeals in a manner that persists over time.  相似文献
