A Community-Based Prostate Cancer Screening and Education Program for Asian American Men in Medically Underserved Communities.

This study analyzed data from a community-based prostate cancer (PCa) education and screening program (Prostate Outreach Project; POP) to enhance PCa-related knowledge among medically underserved Asian American men. It also examined PCa screening history, clinical abnormalities based on prostate-specific antigen (PSA) tests and digital rectal examination (DRE) results, and follow-up and PCa diagnosis rates. Participants-521 Asian men (251 Vietnamese, 142 Chinese, and 128 South Asians)-were offered PCa screening using PSA tests and/or DRE and an educational session on PCa. Of these men, 277 completed PCa-related knowledge surveys before and after viewing an educational video. Significant between-group differences in PCa-related knowledge were found at pre-assessment (p < 0.001) but not at post-assessment (p = 0.11), at which time all groups showed improved PCa-related knowledge. Most participants (77.9%) had never received PCa screening, but Vietnamese men had the lowest previous screening rate (17.3%). Chinese men had elevated PSA values and the highest abnormal DRE rates. Of the 125 men with abnormal screening outcomes, only 15.2% had adequate follow-up. Of the 144 men diagnosed with PCa in POP, 11.1% were Asians (seven Chinese, six Vietnamese, and three South Asian). Despite the ethnic heterogeneity among Asian men, a community outreach program may successfully enhance their PCa-related knowledge.

A Pilot Study Evaluating Organochlorine and Organophosphate Pesticide Exposure in Children and Adolescents of Mexican Descent Residing in Hidalgo County, Texas.

Children and adolescents of Mexican descent residing in Hidalgo County (TX) were evaluated for exposure to organochlorine (OC) and organophosphate (OP) pesticides. A convenience sample of 60 participants enrolled in our pilot study. The lipid-adjusted serum concentrations of nine OC metabolites and creatinine-adjusted urinary concentrations of six OP metabolites were measured and compared with data from the Centers for Disease Control and Prevention's Fourth Report on Human Exposure to Environmental Chemicals. Descriptive statistics were used to summarize the concentration levels for each metabolite. Study participants were aged 5-18 years. For most of the OC and OP metabolites, our findings showed that participants had concentration levels within the distributional range of the national data. However, notable outlying levels (greater than the 95th percentile in the Fourth Report) were identified for the following OC metabolites: gamma-hexachlorocyclohexane, p,p'-dichlorodiphenyldichloroethene, and p,p'-dichlorodiphenyltrichloroethane. Among the children aged 5-11 years, one child had an outlying value for the OP metabolite: dimethylphosphate. Our findings on the levels of OC and OP pesticide exposure enhances the credibility of national estimates, and can serve as baselines for children and adolescents of Mexican descent residing in Lower Rio Grande Valley. Furthermore, our study contributes to the lacunae of knowledge regarding environmental exposures and presses further investigation of outlying OC and OP exposure levels.

Ambivalence: A Key to Clinical Trial Participation?

Trust exerts a multidimensional influence at the interpersonal level in the clinical trials setting. Trust and distrust are dynamic states that are impacted, either positively or negatively, with each participant-clinical trials team interaction. Currently, accepted models of trust posit that trust and distrust coexist and their effects on engagement and retention in clinical trials are mediated by ambivalence. While understanding of trust has been informed by a robust body of work, the role of distrust and ambivalence in the trust building process are less well understood. Furthermore, the role of ambivalence and its relationship to trust and distrust in the clinical trials and oncology settings are not known. Ambivalence is a normal and uncomfortable state in the complex decision making process that characterizes the recruitment and active treatment phases of the clinical trials experience. The current review was conducted to understand the constructs of ambivalence as a mediator of trust and distrust among vulnerable, minority participants through different stages of the oncology clinical trials continuum, its triggers and the contextual factors that might influence it in the setting of minority participation in oncology clinical trials. In addition, the researchers have sought to link theory to clinical intervention by investigating the feasibility and role of Motivational Interviewing in different stages of the clinical trials continuum. Findings suggest that ambivalence can be processed and managed to enable a participant to generate a response to their ambivalence. Thus, recognizing and managing triggers of ambivalence, which include, contradictory goals, role conflicts, membership dualities, and supporting participants through the process of reducing ambivalence is critical to successfully managing trust. Contextual factors related to the totality of one's previous health-care experience, specifically among the marginalized or vulnerable, can contribute to interpersonal ambivalence. In addition, changes in information gathering as a moderator of interpersonal ambivalence may have enormous implications for gathering, assessing, and accepting health information. Finally, motivational Interviewing has widespread applications in healthcare settings, which includes enabling participants to navigate ambivalence in shared-decision making with their clinician, as well as executing changes in participant behavior. Ultimately, the Integrated Model of Trust can incorporate the role of therapeutic techniques like Motivational Interviewing in different stages of the clinical trials continuum. Ambivalence is a key component of clinical trial participation; like trust, ambivalence can be managed and plays a major role in the management of trust in interpersonal relationships over time. The management of ambivalence may play a major role in increasing clinical trial participation particularly among the marginalized or the vulnerable, who may be more susceptible to feelings of ambivalence.

A Lifestyle Intervention via Email in Minority Breast Cancer Survivors: Randomized Parallel-Group Feasibility Study.

BACKGROUND: Our data have indicated that minority breast cancer survivors are receptive to participating in lifestyle interventions delivered via email or the Web, yet few Web-based studies exist in this population. OBJECTIVE: The aim of this study was to examine the feasibility and preliminary results of an email-delivered diet and activity intervention program, "A Lifestyle Intervention Via Email (ALIVE)," delivered to a sample of racial and ethnic minority breast cancer survivors. METHODS: Survivors (mean age: 52 years, 83% [59/71] African American) were recruited and randomized to receive either the ALIVE program's 3-month physical activity track or its 3-month dietary track. The fully automated system provided tools for self-monitoring and goal setting, tailored content, and automated phone calls. Descriptive statistics and mixed-effects models were computed to examine the outcomes of the study. RESULTS: Upon completion, 44 of 71 survivors completed the study. Our "intention-to-treat" analysis revealed that participants in the physical activity track made greater improvements in moderate to vigorous activity than those in the dietary track (+97 vs. +49 min/week, P<.001). Similarly, reductions in total sedentary time among those in the physical activity track (-304 vs. -59 min/week, P<.001) was nearly 5 times greater than that for participants in the dietary track. Our completers case analysis indicated that participants in the dietary track made improvements in the intake of fiber (+4.4 g/day), fruits and vegetables (+1.0 cup equivalents/day), and reductions in saturated fat (-2.3 g/day) and trans fat (-0.3 g/day) (all P<.05). However, these improvements in dietary intake were not significantly different from the changes observed by participants in the physical activity track (all P>.05). Process evaluation data indicated that most survivors would recommend ALIVE to other cancer survivors (97%), were satisfied with ALIVE (82%), and felt that ALIVE was effective (73%). However, survivors expressed concerns about the functionality of the interactive emails. CONCLUSIONS: ALIVE appears to be feasible for racial and ethnic minority cancer survivors and showed promising results for larger implementation. Although survivors favored the educational content, a mobile phone app and interactive emails that work on multiple email domains may help to boost adherence rates and to improve satisfaction with the Web-based platform.

Building trust and diversity in patient-centered oncology clinical trials: An integrated model.

BACKGROUND/AIMS: Trust is the cornerstone of clinical trial recruitment and retention. Efforts to decrease barriers and increase clinical trial participation among diverse populations have yielded modest results. There is an urgent need to better understand the complex interactions between trust and clinical trial participation. The process of trust-building has been a focus of intense research in the business community. Yet, little has been published about trust in oncology clinical trials or the process of building trust in clinical trials. Both clinical trials and business share common dimensions. Business strategies for building trust may be transferable to the clinical trial setting. This study was conducted to understand and utilize contemporary thinking about building trust to develop an Integrated Model of Trust that incorporates both clinical and business perspectives. METHODS: A key word-directed literature search of the PubMed, Medline, Cochrane, and Google Search databases for entries dated between 1 January 1985 and 1 September 2015 was conducted to obtain information from which to develop an Integrated Model of Trust. RESULTS: Successful trial participation requires both participants and clinical trial team members to build distinctly different types of interpersonal trust to effect recruitment and retention. They are built under conditions of significant emotional stress and time constraints among people who do not know each other and have never worked together before. Swift Trust and Traditional Trust are sequentially built during the clinical trial process. Swift trust operates during the recruitment and very early active treatment phases of the clinical trial process. Traditional trust is built over time and operates during the active treatment and surveillance stages of clinical trials. The Psychological Contract frames the participants' and clinical trial team members' interpersonal trust relationship. The "terms" of interpersonal trust are negotiated through the psychological contract. Contract renegotiation occurs in response to cyclical changes within the trust relationship throughout trial participation. CONCLUSION: The Integrated Model of Trust offers a novel framework to interrogate the process by which diverse populations and clinical trial teams build trust. To our knowledge, this is the first model of trust-building in clinical trials that frames trust development through integrated clinical and business perspectives. By focusing on the process, rather than outcomes of trust-building diverse trial participants, clinical trials teams, participants, and cancer centers may be able to better understand, measure, and manage their trust relationships in real time. Ultimately, this may foster increased recruitment and retention of diverse populations to clinical trials.

The Past Does Matter: a Nursing Perspective on Post Traumatic Slave Syndrome (PTSS).

Few have reviewed the impact of post traumatic slave syndrome (PTSS) on the issues of inequities, especially as it pertains to mental and physical health. Furthermore, the impact of PTSS on the social determinants of health is an area that has been researched by few investigators. The possibilities that the impact of slavery and/or major stress events in the life of a population can become trans-generational are lost to history. Think about what is taking place in cities around the country and then think about racist socialization (internalized racism) and its impact on our society. Combining these factors with the lack of real medical care and the bias that plagues our medical establishment and society in general, the net result is a society faced with inequities that seem to be unresolvable, simply because we have lost perspective about a major root cause of the problem.

Prostate Cancer Education, Detection, and Follow-Up in a Community-Based Multiethnic Cohort of Medically Underserved Men.

The Prostate Outreach Project (POP) provided free prostate cancer (PCa) education and early detection to medically underserved communities. POP recruited participants in medically underserved communities. PCa education and detection events occurred in POP locations (static) or natural gathering places (mobile) within the community. PCa education was delivered by video and evaluated using a questionnaire. Screening consisted of serum prostate-specific antigen and digital rectal examination. A navigated follow-up strategy was utilized to provide medical care for participants with abnormal screening examinations (ASE). POP recruited 4,420 men, 62.8% (2,667) were African American (AA). Most participants had a high school education and no prior screening. Fifty-four percent (2,159) were uninsured and 41% (1,811) had no access to a physician. PCa knowledge increased following the educational video. Prostate-specific antigen levels were elevated in 9.8% (436), while 6.9% (233) had an abnormal digital rectal examination. Follow-up among 609 men with ASE was successful in 40% (244), despite a navigated approach. Overall, 3.3% (144) cancers were diagnosed among the POP with AA participants exhibiting a significantly higher incidence. Recruitment, education, and PCa testing among a medically underserved cohort was successful. However, failure to follow through on ASE could contribute to maintaining the disparity in PCa outcomes noted among AAs and the medically underserved if not addressed.

User Perceptions and Reactions to an Online Cancer Risk Assessment Tool: a Process Evaluation of Cancer Risk Check.

Online cancer risk assessment tools, which provide personalized cancer information and recommendations based on personal data input by users, are a promising cancer education approach; however, few tools have been evaluated. A randomized controlled study was conducted to compare user impressions of one tool, Cancer Risk Check (CRC), to non-personalized educational information delivered online as series of self-advancing slides (the control). CRC users (N = 1452) rated the tool to be as interesting as the control (p > .05), but users were more likely to report that the information was difficult to understand and not applicable to them (p < .05). Information seeking and sharing also were lower among CRC users; thus, although impressions of CRC were favorable, it was not shown to be superior to existing approaches. We hypothesized CRC was less effective because it contained few visual and graphical elements; therefore, CRC was compared to a text-based control (online PDF file) post hoc. CRC users rated the information to be more interesting, less difficult to understand, and better able to hold their attention (p < .05). Post hoc results suggest the visual presentation of risk is critical to tool success.

Cost-Effectiveness Analysis of a Capitated Patient Navigation Program for Medicare Beneficiaries with Lung Cancer.

OBJECTIVE: To assess the cost-effectiveness of implementing a patient navigation (PN) program with capitated payment for Medicare beneficiaries diagnosed with lung cancer. DATA SOURCES/STUDY SETTING: Cost-effectiveness analysis. STUDY DESIGN: A Markov model to capture the disease progression of lung cancer and characterize clinical benefits of PN services as timeliness of treatment and care coordination. Taking a payer's perspective, we estimated the lifetime costs, life years (LYs), and quality-adjusted life years (QALYs) and addressed uncertainties in one-way and probabilistic sensitivity analyses. DATA COLLECTION/EXTRACTION METHODS: Model inputs were extracted from the literature, supplemented with data from a Centers for Medicare and Medicaid Services demonstration project. PRINCIPAL FINDINGS: Compared to usual care, PN services incurred higher costs but also yielded better outcomes. The incremental cost and effectiveness was $9,145 and 0.47 QALYs, respectively, resulting in an incremental cost-effectiveness ratio of $19,312/QALY. One-way sensitivity analysis indicated that findings were most sensitive to a parameter capturing PN survival benefit for local-stage patients. CE-acceptability curve showed the probability that the PN program was cost-effective was 0.80 and 0.91 at a societal willingness-to-pay of $50,000 and $100,000/QALY, respectively. CONCLUSION: Instituting a capitated PN program is cost-effective for lung cancer patients in Medicare. Future research should evaluate whether the same conclusion holds in other cancers.

Five National Cancer Institute-designated cancer centers' data collection on racial/ethnic minority participation in therapeutic trials: a current view and opportunities for improvement.

BACKGROUND: To ensure that National Institutes of Health-funded research is relevant to the population's needs, specific emphasis on proportional representation of minority/sex groups into National Cancer Institute (NCI) cancer centers' clinical research programs is reported to the NCI. METHODS: EMPaCT investigators at 5 regionally diverse comprehensive cancer centers compared data reported to the NCI for their most recent Cancer Center Support Grant competitive renewal to assess and compare the centers' catchment area designations, data definitions, data elements, collection processes, reporting, and performance regarding proportional representation of race/ethnicity and sex subsets. RESULTS: Cancer centers' catchment area definitions differed widely in terms of their cancer patient versus general population specificity, levels of specificity, and geographic coverage. Racial/ethnic categories were similar, yet were defined differently, across institutions. Patients' socioeconomic status and insurance status were inconsistently captured across the 5 centers. CONCLUSIONS: Catchment area definitions and the collection of patient-level demographic factors varied widely across the 5 comprehensive cancer centers. This challenged the assessment of success by cancer centers in accruing representative populations into the cancer research enterprise. Accrual of minorities was less than desired for at least 1 racial/ethnic subcategory at 4 of the 5 centers. Institutions should clearly and consistently declare their primary catchment area and the rationale and should report how race/ethnicity and sex are defined, determined, collected, and reported. More standardized, frequent, consistent collection, reporting, and review of these data are recommended, as is a commitment to collecting socioeconomic data, given that socioeconomic status is a primary driver of cancer disparities in the United States.

State-of-the-science of patient navigation as a strategy for enhancing minority clinical trial accrual.

BACKGROUND: Patient navigation programs are emerging that aim to address disparities in clinical trial participation among medically underserved populations, including racial/ethnic minorities. However, there is a lack of consensus on the role of patient navigators within the clinical trial process as well as outcome measures to evaluate program effectiveness. METHODS: A review of the literature was conducted of PubMed, Medline, CINHAL, and other sources to identify qualitative and quantitative studies on patient navigation in clinical trials. The search yielded 212 studies, of which only 12 were eligible for this review. RESULTS: The eligible studies reported on the development of programs for patient navigation in cancer clinical trials, including training and implementation among African Americans, American Indians, and Native Hawaiians. A low rate of clinical trial refusal (range, 4%-6%) was reported among patients enrolled in patient navigation programs. However, few studies reported on the efficacy of patient navigation in increasing clinical treatment trial enrollment. CONCLUSIONS: Outcome measures are proposed to assist in developing and evaluating the efficacy and/or effectiveness of patient navigation programs that aim to increase participation in cancer clinical trials. Future research is needed to evaluate the efficacy of patient navigators in addressing barriers to clinical trial participation and increasing enrollment among medically underserved cancer patients.

African-American breast cancer survivors' preferences for various types of physical activity interventions: a Sisters Network Inc. web-based survey.

BACKGROUND: Needs assessments are essential to developing lifestyle interventions for minority populations. To our knowledge, no physical activity (PA) needs assessment studies have been conducted for African-American (AA) breast cancer survivors. The purpose of this study was to determine the PA intervention preferences of AA breast cancer survivors and determine whether these preferences differ according to medical and sociodemographic factors. METHODS: AA breast cancer survivors (n = 475, mean age = 54 years) were recruited using ads sent via email and social media sites. Preferences for the mode of intervention delivery were assessed via web-based questionnaires. Descriptive statistics were used to characterize their interests in PA interventions, and subgroup differences were assessed. RESULTS: About 49 % (142 out of 291) of the participants who completed the survey were obese and 54 % did not meet the recommended guidelines for PA. Most (90 %) participants reported that they could participate in PA, and many (67 %) indicated that they were interested in receiving program materials. Participants expressed the greatest interest in email (50 %)-, web (48 %)-, or mail-based (45 %) over group (39 %), and telephone (10 %). Women also expressed the greatest interest in participating in studies that promoted walking and resistance or strength training. Intervention preferences did not differ significantly (P > 0.05) across sociodemographic or medical factors. CONCLUSION: Most AA breast cancer survivors can participate in PA, and many are interested in interventions that promoted walking and resistance training and were delivered via the email or web. The development of culturally sensitive interventions that provide activities consistent with preferences can assist AA breast cancer survivors to adopt and maintain a healthy lifestyle. IMPLICATIONS FOR CANCER SURVIVORS: Despite evidence that AA breast cancer survivors are at increased risk for poor breast cancer-specific outcomes, they are underrepresented in clinical trials promoting positive health behaviors. In this study, we propose to assess their exercise preferences and receptivity to a culturally appropriate PA intervention developed in collaboration with the Sisters Network Inc. Health promotion programs developed in collaboration with a community-based organization may aid in the development of research tools and resources that AA breast cancer survivors are receptive to using.

Lifestyle behaviors of African American breast cancer survivors: a Sisters Network, Inc. study.

INTRODUCTION: African American breast cancer survivors experience poor cancer outcomes that may, in part, be remedied by healthy lifestyle choices. Few studies have evaluated the health and lifestyle behaviors of this population. The purpose of this study was to characterize the health and lifestyle habits of African American breast cancer survivors and evaluate the socio-demographic and medical correlates of these behaviors. METHODS: A total of 470 African American breast cancer survivors (mean age = 54 years) participated in an online survey. All participants completed measures assessing medical and demographic characteristics, physical activity, and sedentary behavior. Chi-square tests for association, nonparametric tests, and logistic regression models were used to assess associations. All statistical tests were two sided. RESULTS: Almost half (47%) of the women met the current guidelines for physical activity, almost half (47%) were obese, and many reported having high blood pressure (53%) or diabetes (21%). The prevalence of high blood pressure, diabetes, and high cholesterol increased by age (P<0.001), and obese women had a higher prevalence of high blood pressure (63% vs. 44%) and diabetes (21% vs. 12%) than did non-obese women (all P<0.05). Obese women participated in significantly fewer total minutes of physical activity per week (100 minutes/week) than did non-obese women (150 minutes/week; P<0.05). The number of comorbid conditions was associated with increased odds for physical inactivity (odds ratio = 1.40) and obesity (odds ratio = 2.22). CONCLUSION: Many African American breast cancer survivors had chronic conditions that may be exacerbated by poor lifestyle choices. Our results also provide evidence that healthy lifestyle interventions among obese African American breast cancer survivors are urgently needed.

Associations between body size and serum estradiol and sex hormone-binding globulin levels in premenopausal African American women.

CONTEXT: African American (AA) women have the highest rates of premenopausal breast cancer; however, it is unclear whether body size contributes to the hormonal patterns potentially associated with increased breast cancer risk in these women. OBJECTIVE: To characterize the association between body size and serum levels of estradiol and sex hormone-binding globulin (SHBG) levels in a sample of premenopausal AA women. DESIGN: A total of 164 premenopausal AA women who were not pregnant or breastfeeding were recruited for this study. Serum samples were collected during the early follicular phase, and trained staff collected body size measurements. Multiple linear regression models were performed to assess potential associations. MAIN OUTCOME MEASURES: Serum estradiol and SHBG levels. RESULTS: Many (81%) of the women enrolled were overweight or obese. Both waist-to-hip ratio (WHR) (ß = 2.68, P = .008) and waist circumference (WC) (ß = 2.02, P = .046) were positively associated with higher levels of estradiol. All measures of body was significantly and inversely associated with SHBG levels (all P < .05). CONCLUSIONS: Premenopausal AA women with higher WHR or larger WC may have higher levels of estradiol and lower levels of SHBG. Thus, WHR or WC may be better indicators for assessing hormonal patterns implicated in breast cancer pathogenesis in these women.

Impact of race and ethnicity on features and outcome of ductal carcinoma in situ of the breast.

BACKGROUND: The impact of race and ethnicity on the biologic features and outcome variables of women who are diagnosed with preinvasive breast cancer-ductal carcinoma in situ (DCIS)-has not been addressed widely in the published literature. METHODS: Patient demographic, clinical, and pathologic features and outcome variables were analyzed with respect to the patient's initial self-reported race/ethnicity among women who received treatment for a diagnosis of pure DCIS from 1996 to 2009. RESULTS: Of 1902 patients, 1411 were white (74.2%), 214 were African American (11.3%), 175 were Hispanic (9.1%), and 102 were Asian/Pacific Islander (5.4%). The majority of patients were between ages 41 and 70 years (83%). Patients of Hispanic and Asian/Pacific Islander descent were significantly younger than white and African American patients (P < .001). DCIS size and grade, the presence of necrosis, and the frequency of breast-conserving surgery did not differ significantly between groups. African American patients aged >70 years and Hispanic patients aged <50 years were significantly more likely to have estrogen receptor-positive DCIS than patients of other races in the same age categories (P < .001). Adjuvant radiotherapy and tamoxifen were received significantly less often by white women (P < .001). At a median follow-up of 4.8 years (range, 1-14 years), recurrence rates and the development of contralateral breast cancer did not differ significantly among racial/ethnic groups when stratified by treatments received. CONCLUSIONS: There was variation in age at presentation, biologic features, and treatment of DCIS among the different ethnic groups. Additional studies with larger numbers of ethnic minority patients are needed to confirm whether the consistent application of evidence-based treatment practices presents an opportunity for reducing disparities in patients with DCIS.

Associations among physical activity, body mass index, and health-related quality of life by race/ethnicity in a diverse sample of breast cancer survivors.

BACKGROUND: Health-related quality of life (HRQOL), body mass index (BMI), and physical activity (PA) levels have all been associated with prognosis following breast cancer and may explain partially the higher mortality for breast cancer in certain racial/ethnic subgroups. In this study, associations between PA, BMI, and HRQOL by race were examined in a sample of breast cancer survivors. METHODS: Measures of PA, BMI, and HRQOL as well as demographic and medical characteristics of women (N = 3013, 13% nonwhite) who participated in the Women's Healthy Eating and Living Study were assessed at baseline. Analysis of covariance was used to examine the relationship between PA and obesity with HRQOL outcomes. Statistical tests were 2-sided. RESULTS: African American women were less likely to meet guidelines for PA and more likely to be obese than women from other ethnic groups (P < .05). In adjusted models, women who met guidelines for PA reported significantly higher physical health composite (point differences ranged from 10.5 to 21.2 points, all P < .05) and vitality (point differences ranged from 9.9 to 16.5 points, all P < .05) scores than those who did not, regardless of race/ethnicity. Associations between obesity and HRQOL were mixed with fewer associations for Asian American and African American women and stronger associations for whites. CONCLUSIONS: Breast cancer survivors from racially and ethnically diverse populations have lower levels of PA and higher rates of obesity that are generally associated with poorer HRQOL. Culturally sensitive PA and weight loss interventions may improve these lifestyle characteristics and result in improved HRQOL.

A randomized parallel-group dietary study for stages II-IV ovarian cancer survivors.

OBJECTIVE: Few studies have examined the dietary habits of ovarian cancer survivors. Therefore, we conducted a study to assess the feasibility and impact of two dietary interventions for ovarian cancer survivors. METHODS: In this randomized, parallel-group study, 51 women (mean age, 53 years) diagnosed with stages II-IV ovarian cancer were recruited and randomly assigned to a low fat, high fiber (LFHF) diet or a modified National Cancer Institute diet supplemented with a soy-based beverage and encapsulated fruit and vegetable juice concentrates (FVJCs). Changes in clinical measures, serum carotenoid and tocopherol levels, dietary intake, anthropometry, and health-related quality of life (HRQOL) were assessed with paired t-tests. RESULTS: The recruitment rate was 25%, and the retention rate was 75% at 6 months. At baseline, 28% and 45% of women met guidelines for intake of fiber and of fruits and vegetables, respectively. After 6 months, total serum carotenoid levels and α- and ß-carotene concentrations were significantly increased in both groups (P<0.01); however, ß-carotene concentrations were increased more in the FVJC group. Serum ß-cryptoxanthin levels, fiber intake (+5.2g/day), and daily servings of juice (+0.9 servings/day) and vegetables (+1.3 servings/day) were all significantly increased in the LFHF group (all P<0.05). Serum levels of albumin, lutein and zeaxanthin, retinol, and retinyl palmitate were significantly increased in the FVJC group (all P<0.05). No changes in cancer antigen-125, anthropometry, or HRQOL were observed. CONCLUSION: Overall, this study supports the feasibility of designing dietary interventions for stages II-IV ovarian cancer survivors and provides preliminary evidence that a low fat high fiber diet and a diet supplemented with encapsulated FVJC may increase phytonutrients in ovarian cancer survivors.

The role of patient navigators in eliminating health disparities.

Despite many important efforts to increase equity in the US health care system, not all Americans have equal access to health care-or similar health outcomes. With the goal of lowering costs and increasing accessibility to health care, the nation's new health care reform legislation includes certain provisions that expand health insurance coverage to uninsured and underinsured populations, promote medical homes, and support coordination of care. These provisions may help narrow existing health care disparities. Many of the most vulnerable patients, however, may continue to have difficulty accessing and navigating the complex US health care delivery system. This article explores the unique role that patient navigation can play in improving health outcomes for racial and ethnic minorities, as well as other underserved populations, in the context of a changing healthcare environment. Patient navigators can not only facilitate improved health care access and quality for underserved populations through advocacy and care coordination, but they can also address deep-rooted issues related to distrust in providers and the health system that often lead to avoidance of health problems and non-compliance with treatment recommendations. By addressing many of the disparities associated with language and cultural differences and barriers, patient navigators can foster trust and empowerment within the communities they serve. Specific patient navigator activities are discussed, and metrics to evaluate program efforts are presented.

Policy implications of early onset breast cancer among Mexican-origin women.

BACKGROUND: Overall, Latinas are more likely to be diagnosed with a more advanced stage of breast cancer and are 20% more likely to die of breast cancer than non-Hispanic white women. It is estimated that from 2003 to 2006, $82.0 billion in direct medical care expenditures, in addition to 100,000 lives annually, could be saved by eliminating health disparities experienced by Latinos and increasing the use of up to 5 preventive services in the United States. An additional 3700 lives could be saved if 90% of women aged ≥40 years were recently screened for breast cancer. METHODS: The authors examined the risk for breast cancer in a case-control, population-based sample of Mexican-origin women in Harris County, Texas (n=714), where the rates of breast cancer mortality for Latina women have doubled since 1990. RESULTS: Half of breast cancer cases (n=119) were diagnosed in women aged <50 years. In a multivariate model, women who had a family history of breast cancer (odds ratio [OR], 4.3), who were born in Mexico and had high levels of language acculturation (OR, 2.5), and who did not have health insurance (OR, 1.6) had the highest risk for breast cancer. CONCLUSIONS: Because the current results indicated that Mexican-origin women are at high-risk for early onset, premenopausal breast cancer, the authors recommended policies that target screening, education, and treatment to prevent increased disparities in mortality. The authors concluded that the inclusion of community members and policymakers as partners in these endeavors would further safeguard against an increase in cancer health disparities and aid in formulating a policy agenda congruent with scientifically based, community-driven policy efforts that address breast cancer screening, education, and treatment in this vulnerable population.
