The overall 5-year relative survival rate for all cancers combined is now 68%, and there are over 16.9 million survivors in the United States. Evidence from laboratory and observational studies suggests that factors such as diet, physical activity, and obesity may affect risk for recurrence and overall survival after a cancer diagnosis. The purpose of this American Cancer Society guideline is to provide evidence-based, cancer-specific recommendations for anthropometric parameters, physical activity, diet, and alcohol intake for reducing recurrence and cancer-specific and overall mortality. The audiences for this guideline are health care providers caring for cancer survivors as well as cancer survivors and their families. The guideline is intended to serve as a resource for informing American Cancer Society programs, health policy, and the media. Sources of evidence that form the basis of this guideline are systematic literature reviews, meta-analyses, pooled analyses of cohort studies, and large randomized clinical trials published since 2012. Recommendations for nutrition and physical activity during cancer treatment, informed by current practice, large cancer care organizations, and reviews of other expert bodies, are also presented. To provide additional context for the guidelines, the authors also include information on the relationship between health-related behaviors and comorbidities, long-term sequelae and patient-reported outcomes, and health disparities, with attention to enabling survivors' ability to adhere to recommendations. Approaches to meet survivors' needs are addressed as well as clinical care coordination and resources for nutrition and physical activity counseling after a cancer diagnosis. 相似文献

The FilmArray Blood Culture Identification Panel was validated for nonblood sterile site specimens with clinical impact of rapid identification compared to conventional diagnostics. The panel accurately identified target organisms from 98% of positive broth cultures a median 1.1?day faster than conventional techniques (P?<?0.0001) with potential clinical impact in 22% of cases. 相似文献

In the middle of growing consensus that genomics researchers should offer to return clinically valid, medically relevant, and medically actionable findings identified in the course of research, psychiatric genetics researchers face new challenges. As they uncover the genetic architecture of psychiatric disorders through genome‐wide association studies and integrate whole genome and whole exome sequencing to their research, there is a pressing need for examining these researchers' views regarding the return of results (RoR) and the unique challenges for offering RoR from psychiatric genetics research. Based on qualitative interviews with 39 psychiatric genetics researchers from different countries operating at the forefront of their field, we provide an insider's view of researchers' practices regarding RoR and the most contentious issues in psychiatry researchers' decision‐making around RoR, including what are the strongest ethical, scientific, and practical arguments for and against offering RoR from this research. Notably, findings suggest that psychiatric genetics researchers (85%) overwhelmingly favor offering RoR of at least some findings, but only 22% of researchers are returning results. Researchers identified a number of scientific and practical concerns about RoR, and about how to return results in a responsible way to patients diagnosed with a severe psychiatric disorder. Furthermore, findings help highlight areas for further discussion and resolution of conflicts in the practice of RoR in psychiatric genetics research. As the pace of discovery in psychiatric genetics continues to surge, resolution of these uncertainties gains greater urgency to avoid ethical pitfalls and to maximize the positive impact of RoR. 相似文献

AbstractIn our recent work with clinician educators leading UME small groups, we noticed a phenomenon – many clinician educators are saying they don’t teach, they just facilitate. Medical schools have moved to a new model of curriculum that integrates basic, clinical, and social science concepts. As curriculum shifts, so too must the definition and role of a teacher in medical education. The purpose of this article is to explore the work of current clinician educators and to encourage clinician educators to embrace their teaching role and seek educator development opportunities. In this article, we explore the history of how and why the word “teaching” became taboo for clinician educators. Then we explain the current state of the complex work of teaching for today’s clinician educators and its implications for educator development. 相似文献

IntroductionShared decision-making incorporates patients’ values and preferences to achieve high-quality decisions. The objective of this study was to develop an acceptable patient decision aid to facilitate shared decision-making for the management of small renal masses (SRMs).MethodsThe International Patient Decision Aids Standards were used to guide an evidence-based development process. Management options included active surveillance, thermal ablation, partial nephrectomy, and radical nephrectomy. A literature review was performed to provide incidence rates for outcomes of each option. Once a prototype was complete, alpha-testing was performed using a 10-question survey to assess acceptability with patients, patient advocates, urologists, and methodological experts. The primary outcome was acceptability of the decision aid.ResultsA novel patient decision aid was created to facilitate shared decision-making for the management of SRMs. Acceptability testing was performed with 20 patients, 10 urologists, two patient advocates, and one methodological expert. Responders indicated the decision aid was appropriate in length (82%, 27/33), well-balanced (82%, 27/33), and had language that was easy to follow (94%, 31/33). All patient responders felt the decision aid would have been helpful during their consultation and would recommend the decision aid for future patients (100%, 20/20). Most urologists reported they intend to use the decision aid (90%, 9/10).ConclusionsA novel patient decision aid was created to facilitate shared decision-making for management of SRMs. This clinical tool was acceptable with patients, patient advocates, and urologists and is freely available at: https://decisionaid.ohri.ca/decaids.html. 相似文献
