Long-term effectiveness of an E-based survivorship care plan for breast cancer survivors: A quasi-experimental study

ObjectiveThe purpose of this study was to evaluate the effect of a web-based survivorship care plan (SCP) computerized application (APP): (SCP-A) on women’s unmet needs, fear of recurrence, symptom distress, anxiety, depression, and quality of life (QoL).MethodsWomen diagnosed with breast cancer, who had completed their primary treatment but less than 5 years without a sign of recurrence (N = 165) were randomized to a SCP-A or a control group. Self-reported questionnaires were completed by the both groups at baseline (T0), 5 weeks (T1), 3 months (T2), 6 months (T3), and 12 months (T4).ResultsControlling for relevant covariates, mixed effect model analyses revealed a significant decrease in women in the SCP-A group compared to the control group for total unmet needs since T3 (p < .004) and fear of recurrence since T4 (p = .02). Women in the SCP-A group also reported significant improvements in QoL at T4 (p < .001) relative to those in the control group.ConclusionProviding SCP using an information website application for women with breast cancer can decrease unmet needs, fear of recurrence, and improve quality of life during short-term and long-term use.Practice ImplicationsWeb-based information that provides survivorship care plans for breast cancer survivors are beneficial.     

最小子野宽度对肺癌容积调强弧形治疗计划质量的影响

目的:探讨肺癌容积调强弧形治疗（VMAT）计划中,最小子野宽度对放疗计划质量的影响。方法:选择病理证实为肺癌的患者12例,计划靶区处方剂量为60 Gy/30次。使用Monaco治疗计划系统设计全弧VMAT计划,计算网格为0.3 cm,采用6 MV X射线,每个弧的最大控制点数为200。计算不确定度为1%。最小子野宽度依次选取0.5、0.7、1.0、1.2和1.5 cm。以最小子野宽度为1.0 cm的计划为参考,与其他子野宽度下的计划相比较,分析各剂量学指标随最小子野宽度变化的情况。结果:随着最小子野宽度增大为1.2、1.5 cm时,靶区Dmean、D2变化明显（P?0.05）。相比参考最小子野宽度1.0 cm,最小子野宽度为1.5 cm时,适形度指数变化较大（Z=-2.694, P?0.05）;最小子野宽度为0.5、0.7、1.2和1.5 cm时,靶区覆盖率相差较明显（Z=-2.904、-3.061、-2.747、-2.941, P?0.05）。最小子野宽度1.0 cm时,VMAT计划平均机器跳数为684.4 MU;最小子野宽度为0.5、0.7、1.2、1.5 cm时,计划的平均机器跳数分别为为972.8、763.8、660.1、665.3 MU。控制点数随着最小子野宽度的增大呈降低趋势。结论:利用Monaco系统设计肺癌VMAT计划,最小子野宽度为1.0 cm时VMAT计划的质量更好。通过调整VMAT计划的最小子野宽度可大大降低机器跳数,提高射束的有效使用率,同时提高患者的治疗舒适度。

基于生物学优化肿瘤放射治疗计划的评估函数研究

目的：从生物学优化肿瘤放射治疗计划的角度来提出可用于评估放射治疗方案可行性的评估函数。方法：在以细胞受到照射后的再修复、再群体化、细胞周期的再分布、肿瘤内乏氧细胞的再氧合,即＂4R理论＂[1]的基础上,分析生物效应剂量函数BED的变种公式,最后得出3个用于评估肿瘤放疗计划好坏的评估函数。再利用评估函数试验性的分析文献报道过的肿瘤放射治疗方案,并与对应的方案结果进行比对,理论上评价评估函数的可行性。结果：综合分析已有治疗方案参数与评估函数理论参数基本一致。结论：基于生物学优化肿瘤放射治疗计划的评估函数在临床上用来预判治疗方案是可行的。     

Empowerment Through Mentorship and Leadership

Leadership is vital to future growth and change in the dental hygiene profession.Background and PurposeAs health care reform emerges, state practice acts expand and new models of dental hygiene practice are created and implemented, dental hygienists will assume leadership positions that may be quite different from the more traditional leadership roles they assume today. These dental hygienist leaders will envision, creatively design and implement oral health care programs to improve the oral health of the public. Mentoring, a vital component of leadership development, is critical for dental hygienists to acquire knowledge, guidance, and growth.MethodsThis paper provides a literature-supported overview of leadership and mentoring principles applicable to dental hygienists in their personal and professional lives. Opportunities for dental hygienists to assume leadership roles are also described.ConclusionsDental hygienists are poised to become leaders and vital members of the professional team promoting and integrating oral health care as a part of general health. Consequently, the dental hygienist's leadership roles are likely to expand and can be strengthened through mentoring relationships and mentoring teams. Ultimately, this can increase professional growth and career satisfaction for the dental hygienist as well as improve oral health care for the public.
