Abstract Background Guidelines to provide recommendations about driving restrictions for patients with brain metastases are lacking. We aim to determine whether clinical neurologic examination is sufficient to predict suitability to drive in these patients by comparison with an occupational therapy driving assessment (OTDA). Methods We prospectively evaluated the concordance between neurology assessment of suitability to drive (pass/fail) and OTDA in 41 individuals with brain metastases. Neuro-oncology evaluation included an interview and neurological examination. Participants subsequently underwent OTDA during which a battery of objective measures of visual, cognitive, and motor skills related to driving was administered. Results The mean age of patients who failed OTDA was age 68.9 years vs 59.3 years in the group members who passed (P = .0046). The sensitivity of the neurology assessment to predict driving fitness compared with OTDA was 16.1% and the specificity 90%. The 31 patients who failed OTDA were more likely to fail Vision Coach, Montreal Cognitive Assessment, and Trail Making B tests. Conclusions There was poor association between the assessment of suitability to drive by neurologists and the outcome of the OTDA in patients with brain metastases. Subtle deficits that may impair the ability to drive safely may not be evident on neurologic examination. The positive predictive value was high to predict OTDA failure. Age could be a factor affecting OTDA performance. The results raise questions about the choice of assessments in making recommendations about driving fitness in people with brain metastases. OTDA should be strongly considered in patients with brain metastases who wish to continue driving.

Background: Underrepresentation of African American women as research participants contributes to health disparities. Contemporary studies have focused on clinical trial (CT) participation; epidemiologic and genetic studies utilizing medical records and/or biological samples have received less attention. In partnership with The Links, Incorporated (The Links), a national service organization of professional African American women, this study sought to examine attitudes regarding chart review (CR) studies, genetic studies/biobanking (GEN), and CTs; develop; and evaluate an online education-to-action program. Methods: In phase 1, focus groups were convened with members of The Links to inform the content and format of the program. Phases 2 and 3 involved designing and evaluating the program, respectively. Results: Thirty-four women across three focus groups shared attitudes and perceptions regarding research and provided guidance for program development. Subsequently, 244 women completed the program (77% response rate), including pre- and post-assessments. Participants indicating that they “definitely” or “probably” (responses combined) intend to participate in research increased from 36.5% to 69.3% (pre/post-program). Agreement with the statement “research in the U.S. is ethical” increased (52.9% to 74.4%) as did factual knowledge regarding each of the study types. There was a decrease in reporting “little or no understanding” of study types (Pre/Post: GEN: 66%/24.9%, CR: 62.9%/18.4%, CTs: 40.7%/15.5%). Pre-program, few were “very positive” about the study types (14.3% GEN, 15.0% CR, 28.6% CTs); post-program ratings increased and equalized (42.8% GEN, 43.0% CR, 42.5% CTs). Conclusions: An online education-to-action program targeting professional African American women improved knowledge, perceptions of ethics, and intent to participate in biomedical research.

Abstract Addressing underrepresentation of minorities and women as research participants has largely focused on clinical trials, while little is known about attitudes and knowledge regarding other types of biomedical research, e.g., epidemiologic and genetic studies. These types of studies are essential for advances in cancer research, including development of targeted therapies for women and minorities. As part of an academic/community partnership between Mayo Clinic and The Links, Incorporated, a national volunteer service organization of professional African American women, this study sought to: (1) examine attitudes regarding participation in research involving access to the medical record, genetic studies/biobanking, and clinical trials; and (2) develop and evaluate a novel, targeted online educational program addressing these 3 types of biomedical research. Initial qualitative inquiry via 3 focus groups (n=34) found that most women associated health-related research with clinical trials; few women were familiar with other study types. Women expressed more concerns about how information is collected, used, and shared by investigators than with personal mistreatment in research regardless of study type (genetic research (GEN), chart review (CR), clinical trial (CT)) or the kind of information (social, health, genetic) collected. The importance of investigator transparency regarding the significance of the disease in African Americans, research funding source, the investigator’s agenda, and commitment to the population being studied was emphasized. Qualitative results informed development of the educational program. A total of 244 Links members completed the program (77% response rate) and answered pre- and post-assessments of intentions, attitudes and knowledge. The percent of women indicating that they “definitely” or “probably” intend to participate in research increased from 9.4% to 19.5% and 27.1% to 49.8%, respectively, after program completion. Agreement with the statement “research in the U.S. is ethical” increased from 52.9% to 74.4%. Factual knowledge related to each of the 3 study types also increased. Prior to completing the program many women reported “little or no understanding” of the 3 types of studies (66% GEN, 62.9% CR, 40.7% CT) whereas after program completion, these numbers decreased to 24.9%, 18.4%, and 15.5%, respectively. While few women rated their opinion of the study types as “very positive” prior to beginning the program (14.3% GEN, 15.0% CR, 28.6% CT), upon completion these proportions increased and equalized (42.8% GEN, 43.0% CR, 42.5% CT). Two-month follow-up will evaluate longer-term impact including knowledge dissemination, visiting clinicaltrials.gov, and enrolling in ResearchMatch. An online education-to-action program targeting professional African American women improved knowledge, perceptions of research ethics, and intent to participate in biomedical research.

AbstractThis work is to show which is more relevant to cause local failures (LFs) due to patient setup uncertainty between the planning target volume (PTV) underdosage and the potential target underdosage subject to patient setup uncertainties in head and neck (H&N) cancer treated with volumetric‐modulated arc therapy (VMAT). Thirteen LFs in 10 H&N patients treated by VMAT were analyzed. Measures have been taken to minimize the chances of insufficient target delineation for these patients and the patients were clinically determined to have LF based on the PET/CT scan results by an experienced radiologist and then reviewed by a second experienced radiation oncologist. Two methods were used to identify the possible locations of LF due to underdosage: (a) examining the standard VMAT plan, in which the underdosed volume in the nominal dose distribution (UVN) was generated by subtracting the volumes receiving the prescription doses from PTVs, and (b) plan robustness analysis, in which in addition to the nominal dose distribution, six perturbed dose distributions were created by translating the CT iso‐center in three cardinal directions by the PTV margin. The coldest dose distribution was represented by the minimum of the seven doses in each voxel. The underdosed volume in the coldest dose distribution (UVC) was generated by subtracting the volumes receiving the prescription doses in the coldest dose distribution from the volumes receiving the prescription doses in the nominal dose distribution. UVN and UVC were subsequently examined for spatial association with the locations of LF. The association was tested using the binominal distribution and the Fisher's exact test of independence. We found that of 13 LFs, 11 were associated with UVCs (P = 0.011), while three were associated with UVNs (P = 0.99). We concluded that the possible target underdosage due to patient setup uncertainties appeared to be a more relevant factor associated with LF in VMAT for H&N cancer than the compromised PTV coverage at least for the patients included in this study.

PURPOSE: Hot flashes can be a prominent problem in women with a history of breast cancer. Given concerns regarding the use of hormonal therapies in such patients, other nonhormonal means for treating hot flashes are required. Based on anecdotal information regarding the efficacy of fluoxetine and other newer antidepressants for treating hot flashes, the present trial was developed. PATIENTS AND METHODS: This trial used a double-blinded, randomized, two-period (4 weeks per period), cross-over methodology to study the efficacy of fluoxetine (20 mg/d) for treating hot flashes in women with a history of breast cancer or a concern regarding the use of estrogen (because of breast cancer risk). Eligible patients had to have reported that they averaged at least 14 hot flashes per week; they could have received tamoxifen or raloxifene as long as they were on a stable dose. The major outcome measure was a bivariate construct representing hot flash frequency and hot flash score, analyzed by a classic sums and differences cross-over analysis. RESULTS: Eighty-one randomized women began protocol therapy. By the end of the first treatment period, hot flash scores (frequency × average severity) decreased 50% in the fluoxetine arm versus 36% in the placebo arm. Cross-over analysis demonstrated a significantly greater marked hot flash score improvement with fluoxetine than placebo (P = .02). The results were not adjusted for potential confounding influences, including age and tamoxifen use. The fluoxetine was well tolerated. CONCLUSION: This dose of fluoxetine resulted in a modest improvement in hot flashes.
