Answer questions and earn CME/CNE The American Cancer Society Head and Neck Cancer Survivorship Care Guideline was developed to assist primary care clinicians and other health practitioners with the care of head and neck cancer survivors, including monitoring for recurrence, screening for second primary cancers, assessment and management of long‐term and late effects, health promotion, and care coordination. A systematic review of the literature was conducted using PubMed through April 2015, and a multidisciplinary expert workgroup with expertise in primary care, dentistry, surgical oncology, medical oncology, radiation oncology, clinical psychology, speech‐language pathology, physical medicine and rehabilitation, the patient perspective, and nursing was assembled. While the guideline is based on a systematic review of the current literature, most evidence is not sufficient to warrant a strong recommendation. Therefore, recommendations should be viewed as consensus‐based management strategies for assisting patients with physical and psychosocial effects of head and neck cancer and its treatment.

BACKGROUND: From January through June 2009, 6.1 million children were uninsured in the United States. On average, students with health insurance are healthier and as a result are more likely to be academically successful. Some schools help students obtain health insurance with the help of school nurses. METHODS: This study assessed public school nurses' knowledge and beliefs of the impact of health insurance on students' health and academic success. The study also determined whether public school nurses or their schools were involved in helping students obtain public health insurance, and if so, how they did so. Additionally, the study assessed the public school nurses' perceived benefits of and barriers to helping students obtain public health insurance. A paper-and-pencil survey was sent to a national random sample of 750 public school nurses. The response rate was 56%. RESULTS: Nearly 60% of respondents had helped students enroll in public health insurance. The majority perceived that helping students obtain public health insurance would reduce school absenteeism (90%), improve attention during school (84%), reduce the number of students held back (80%), reduce school dropouts (72%), and increase academic test scores (69%). Although the majority (53%) of nurses thought schools should assist students' parents with filling out public health insurance enrollment forms, some expressed reservations about the process. CONCLUSION: School nurses indicated health insurance is important for the health and academic success of students. These beliefs are congruent with state Child Health Insurance Program (CHIP) directors' perceptions, yet few schools have taken on the role of facilitating student enrollment in public health insurance programs.  相似文献

BACKGROUND: While studies have determined the importance of physical activity in advancing health outcomes, relatively few have explored the relationship between exercise and various health behaviors of adolescents. The purpose of this study is to examine the relationship between frequency and intensity of physical activity and both health risk and health promoting behaviors of adolescents. METHODS: Data were collected from 822 students attending a large, diverse suburban high school in northeast Florida using a self-administered survey. Multivariate analysis of variance (MANOVA) and analysis of variance (ANOVA) tests examined differences on mean health behavior measures on 3 exercise frequency levels (low, medium, and high) and 2 intensity levels (vigorous physical activity [VPA] and moderate physical activity [MPA]). RESULTS: Results showed adolescents engaged in high levels of VPA used marijuana less frequently (p = .05) and reported heavy use of marijuana less frequently (p = .03); consumed greater numbers of healthy carbohydrates (p < .001) and healthy fats in their diets (p < .001); used stress management techniques more frequently (p < .001); and reported a higher quality of sleep (p = .01) than those engaged in low levels of VPA. Fewer differences were found on frequency of MPA and health behaviors of adolescents. CONCLUSIONS: These findings suggest that adolescents who frequently participate in VPA may be less likely to engage in drug use, and more likely to participate in a number of health promoting behaviors. Longitudinal and experimental studies are needed to determine what role frequent VPA may play in the onset and maintenance of health enhancing and protecting behaviors among adolescent populations.  相似文献

Background. Adult participation in clinical trials is low, and many individuals are unaware of trials as an option. Raising awareness about clinical trials and addressing barriers through education is key to increasing enrollment in trials. Methods. To reach communities, the National Cancer Institute (NCI) worked with partners to disseminate clinical trials education resources. Evaluation was conducted to determine the effectiveness of the dissemination approaches on program goals. Results. Survey results indicated that partners disseminated, used, and were satisfied with the program resources. Focus group results corroborated these findings. Conclusions. NCI’s program successfully used partnerships for broad dissemination of resources to improve clinical trials awareness.  相似文献

OBJECTIVES: To develop a comprehensive inventory of state physical education (PE) legislation, examine trends in bill introduction, and compare bill factors. METHODS: State PE legislation from January 2001 to July 2007 was identified using a legislative database. Analysis included components of evidence-based school PE from the Community Guide and other authoritative sources: minutes in PE, PE activity, teacher certification, and an environmental element, including facilities and equipment. Researchers abstracted information from each bill and a composite list was developed. RESULTS: In total, 781 bills were analyzed with 162 enacted. Of the 272 bills that contained at least 1 evidence-based element, 43 were enacted. Only 4 bills included all 4 evidence-based elements. Of these 4, 1 was enacted. Funding was mentioned in 175 of the bills introduced (37 enacted) and an evaluation component was present in 172 of the bills (49 enacted). CONCLUSIONS: Based on this analysis, we showed that PE is frequently introduced, yet the proportion of bills with evidence-based elements is low. Future research is needed to provide the types of evidence required for development of quality PE legislation.  相似文献
