Novel recruitment approaches and operational results for a statewide population Cohort for cancer research: The Healthy Oregon Project.

Background: Cancer health research relies on large-scale cohorts to derive generalizable results for different populations. While traditional epidemiological cohorts often use costly random sampling or self-motivated, preselected groups, a shift toward health system-based cohorts has emerged. However, such cohorts depend on participants remaining within a single system. Recent consumer engagement models using smartphone-based communication, driving projects, and social media have begun to upend these paradigms. Methods: We initiated the Healthy Oregon Project (HOP) to support basic and clinical cancer research. HOP study employs a novel, cost-effective remote recruitment approach to effectively establish a large-scale cohort for population-based studies. The recruitment leverages the unique email account, the HOP website, and social media platforms to direct smartphone users to the study app, which facilitates saliva sample collection and survey administration. Monthly newsletters further facilitate engagement and outreach to broader communities. Results: By the end of 2022, the HOP has enrolled approximately 35,000 participants aged 18-100 years (median = 44.2 years), comprising more than 1% of the Oregon adult population. Among those who have app access, ∼87% provided consent to genetic screening. The HOP monthly email newsletters have an average open rate of 38%. Efforts continue to be made to improve survey response rates. Conclusion: This study underscores the efficacy of remote recruitment approaches in establishing large-scale cohorts for population-based cancer studies. The implementation of the study facilitates the collection of extensive survey and biological data into a repository that can be broadly shared and supports collaborative clinical and translational research.

Prioritizing rural populations in state comprehensive cancer control plans: a qualitative assessment.

PURPOSE: The Centers for Disease Control and Prevention's National Comprehensive Cancer Control Program (NCCCP) requires that states develop comprehensive cancer control (CCC) plans and recommends that disparities related to rural residence are addressed in these plans. The objective of this study was to explore rural partner engagement and describe effective strategies for incorporating a rural focus in CCC plans. METHODS: States were selected for inclusion using stratified sampling based on state rurality and region. State cancer control leaders were interviewed about facilitators and barriers to engaging rural partners and strategies for prioritizing rural populations. Content analysis was conducted to identify themes across states. RESULTS: Interviews (n = 30) revealed themes in three domains related to rural inclusion in CCC plans. The first domain (barriers) included (1) designing CCC plans to be broad, (2) defining "rural populations," and (3) geographic distance. The second domain (successful strategies) included (1) collaborating with rural healthcare systems, (2) recruiting rural constituents, (3) leveraging rural community-academic partnerships, and (4) working jointly with Native nations. The third domain (strategies for future plan development) included (1) building relationships with rural communities, (2) engaging rural constituents in planning, (3) developing a better understanding of rural needs, and (4) considering resources for addressing rural disparities. CONCLUSION: Significant relationship building with rural communities, resource provision, and successful strategies used by others may improve inclusion of rural needs in state comprehensive cancer control plans and ultimately help plan developers directly address rural cancer health disparities.

Financial navigation: Staff perspectives on patients' financial burden of cancer care.

PURPOSE: To describe perceptions of financial navigation staff concerning patients' cancer-related financial burden. METHODS: This qualitative descriptive study used a semi-structured interview guide to examine perceptions of financial navigation staff concerning patients' cancer-related financial burden. Staff who provided financial navigation support services to cancer patients were interviewed from different types of cancer programs across seven states representing rural, micropolitan, and urban settings. Interviews lasted approximately one hour, were audio recorded, and transcribed. Transcripts were double coded for thematic analysis. RESULTS: Thirty-five staff from 29 cancer centers were interviewed. The first theme involved communication issues related to patient and financial navigation staff expectations, timing and the sensitive nature of financial discussions. The second theme involved the multi-faceted impact of financial burden on patients, including stress, difficulty adhering to treatments, and challenges meeting basic, non-medical needs. CONCLUSIONS AND IMPLICATIONS FOR CANCER SURVIVORS: Cancer-related financial burden has a profound impact on cancer survivors' health and non-health outcomes. Discussions regarding cancer-related costs between cancer survivors and healthcare team members could help to normalize conversations and mitigate the multi-faceted determinants and effects of cancer-related financial burden. As treatment may span months and years and unexpected costs arise, having this discussion regularly and systematically is needed.

A Framework for Equitable Partnerships to Promote Cancer Prevention and Control in Rural Settings.

Rural populations continue to experience persistent cancer disparities compared with urban populations particularly in cancers that can be prevented or detected early through screening and vaccination. Although the National Cancer Institute and the larger cancer research community have identified rural community partnerships as the foundation for reducing the disparities, we have identified limited application of community-based participatory research in cancer prevention and control research. Guided by the Community-Based Participatory Research Conceptual Model and our collective experience, we provide a framework for a community-cancer center partnership that focuses on promoting health equity. In this commentary, we articulate that the partnership process must foster capacity for communities and cancer centers, strive for rural representation in clinical trials and biobanking, build a pipeline for dissemination and implementation research, and create a bidirectional flow of knowledge between communities and academic institutions. Authentic partnerships with rural communities should be the ultimate goal of cancer centers, and the process described in this commentary can serve as an initial platform to build capacity and continue to strive toward that goal.

A Coordinated Approach to Implementing Low-Dose CT Lung Cancer Screening in a Rural Community Hospital.

PURPOSE: The authors describe a rural community hospital's approach to lung cancer screening using low-dose CT (LDCT) to address the high incidence of lung cancer mortality. METHODS: An implementation project was conducted, documenting planning, education, and restructuring processes to implement a lung cancer screening program using LDCT in a rural community hospital (population 64,917, Rural-Urban Continuum Code 5) located in a region with the highest lung cancer mortality in Oregon. The hospital and community partners organized the implementation project around five recommendations for an efficient and effective lung cancer screening program that accurately identifies high-risk patients, facilitates timely access to screening, provides appropriate follow-up care, and offers smoking cessation support. RESULTS: Over a 3-year period (2018-2020), 567 LDCT scans were performed among a high-risk population. The result was a 4.8-fold increase in the number of LDCT scans from 2018 to 2019 and 54% growth from 2019 to 2020. The annual adherence rate increased from 51% in 2019 to 59.6% in 2020. Cancer was detected in 2.11% of persons scanned. Among the patients in whom lung cancer was detected, the majority of cancers (66.6%) were categorized as stage I or II. CONCLUSIONS: This rural community hospital's approach involved uniting primary care, specialty care, and community stakeholders around a single goal of improving lung cancer outcomes through early detection. The implementation strategy was intentionally organized around five recommendations for an effective and efficient lung cancer screening program and involved planning, education, and restructuring processes. Significant stakeholder involvement on three separate committees ensured that the program's design was relevant to local community contexts and patient centered. As a result, the screening program's reach and adherence increased each year of the 3-year pilot program.

Identify factors for insufficient (> 2 yr) mammogram screening among Oregonian women.

PURPOSE: Women with breast cancer diagnosed from mammogram screenings have a lower mortality risk than women diagnosed from symptoms. Currently, the U.S Preventive Services Task Force recommends biannual screening for women aged 50-74 years old. In this study, we aimed to identify factors associated with inadequate screening defined as "no mammogram screening within past 2 years" to guide cancer prevention and early detection efforts. METHODS: This study utilized area-based probabilistic sampling survey data, collected across Oregon in 2019. Dataset weights were calculated using a raking approach. Demographic and behavior information were collected with existing validated questionnaire items from national surveys. Weighted multivariable logistic regression analyses with missing-value imputations were conducted to identify factors associated with inadequate mammogram screening. RESULTS: The study included 254 women 50-74 years old without previous breast or ovarian cancer history. 19.29% of the sample reported no mammogram within two years, including 1.57% with no previous mammograms. Following unadjusted analyses, the significant factors included education, occupation status, health insurance and smoking and were therefore included into the adjusted model. In the multivariate adjusted model education remained significant while occupation status, health insurance and smoking were no longer significant. Compared to women with a college graduate degree, women with less than college graduate degree were at higher risk of inadequate screening [OR (95% CI) = 3.23 (1.54, 6.74)]. CONCLUSIONS: Lack of education was significantly associated with inadequate mammogram screening even after adjusting for occupation status, health insurance and smoking, which should prompt further outreach and education.

Interventions to address cancer-related financial toxicity: Recommendations from the field.

PURPOSE: Addressing financial toxicity among cancer patients is a complex process that requires a multifaceted approach, particularly for rural patients who may face additional cost-related barriers to care. In this study, we examined interventions being implemented by financial navigation staff at various cancer centers that help address financial toxicity experienced by oncology patients. METHODS: We conducted semistructured interviews with a convenience sample of financial navigation staff across 29 cancer centers in both rural and urban areas in 7 states. Interviews were audio-recorded and transcribed. Descriptive coding and thematic analysis techniques were used to analyze the data. FINDINGS: Thirty-five participants were interviewed, the majority of whom worked in cancer centers located in rural counties. Participants identified the use of screening tools, patient education, and access to tailored financial assistance resources as best practices. Immediate resource needs included additional financial navigation staff, including lay navigators and community health workers, to promote linkages to local resources. Suggested clinical areas for intervention included proactive and early implementation of financial assessments and discussions between providers and patients, along with training and access to regularly updated resources for those in financial navigator/counselor roles. Participants also discussed the need for policy-level interventions to reform health systems (including employment protections) and health insurance programs. CONCLUSIONS: Implementing proactive methods to screen for and address financial needs of patients is essential to improving cancer-related outcomes. Additional programs and research are needed to help establish systematic and standardized methods to enhance financial navigation services, especially for underserved rural communities.

How cancer programs identify and address the financial burdens of rural cancer patients.

PURPOSE: Financial toxicity is associated with negative patient outcomes, and rural populations are disproportionately affected by the high costs of cancer care compared to urban populations. Our objective was to (1) understand cancer programs' perceptions of rural-urban differences in cancer patients' experiences of financial hardship, (2) evaluate the resources available to cancer patients across the rural-urban continuum, and (3) determine how rural and urban health care teams assess and address financial distress in cancer patients. METHODS: Seven research teams within the Cancer Prevention and Research Control Network conducted semi-structured interviews with cancer program staff who have a role in connecting cancer patients with financial assistance services in both rural and urban counties. Interviews were audio-recorded and transcribed. We identified themes using descriptive content and thematic analysis. RESULTS: We interviewed 35 staffs across 29 cancer care programs in seven states, with roughly half of respondents from programs in rural counties. Participants identified differences in rural and urban patients' experiences of financial hardship related to distance required to travel for treatment, underinsurance, and low socioeconomic status. Insufficient staffing was an identified barrier to addressing rural and urban patients' financial concerns. CONCLUSIONS: Improved financial navigation services could mitigate the effects of financial toxicity experienced by cancer patients, particularly rural patients, throughout treatment and survivorship. Future research is needed to improve how cancer programs assess financial hardship in patients and to expand financial navigation services to better serve rural cancer patients.

Using concept mapping to identify opportunities for HPV vaccination efforts: Perspectives from the Midwest and West Coast.

Human papillomavirus (HPV) infection significantly contributes to the burden of cancer in the United States, despite the existence of a highly effective vaccine. While numerous interventions to address vaccination uptake exist, vaccination rates remain low. We conducted a concept mapping exercise to solicit perspectives on barriers and facilitators to HPV vaccination from state-level stakeholders in five states in the Midwest and West Coast of the U.S. We identified 10 clusters of barriers and facilitators based on participants' statements. For rural areas specifically, clusters rated as most important included education and provider influence; those rated as most feasible were education and coordinated/consistent messaging. Our results suggest that a combination of important (but potentially more difficult to implement) strategies, combined with those rated as most feasible (but potentially less impactful) may be beneficial. Our findings highlight similarities across diverse states, suggesting that states can learn from each other and work together to improve HPV vaccination rates. Using concept mapping proved to be an efficient way to collect information from diverse, stakeholders in different locations, and is a methodology that could be used for program planning in areas beyond HPV vaccination.

Influences on HPV vaccination across levels of the social ecological model: perspectives from state level stakeholders.

Nationally, human papillomavirus (HPV) vaccination rates fall short of the Healthy People 2020 goal of 80% completion. Although strategies to increase these rates exist, low rates persist. We used concept mapping with state-level stakeholders to better understand barriers and facilitators to HPV vaccination. Concept mapping is a participatory research process in which respondents brainstorm ideas to a prompt and then sort ideas into piles. We present results of the brainstorming phase. We recruited participants identified by researchers' professional connections (n = 134) via e-mail invitations from five states (Iowa, South Dakota, Minnesota, Oregon, and Washington) working in adolescent health, sexual health, cancer prevention and control, or immunization. Using Concept Systems' online software we solicited participants' beliefs about what factors have the greatest influence on HPV vaccination rates in their states. From the original sample 58.2% (n = 78) of participants completed the brainstorming activity and generated 372 statements, our team removed duplicates and edited statements for clarity, which resulted in 172 statements. We coded statements using the Social Ecological Model (SEM) to understand at what level factors affecting HPV vaccination are occurring. There were 53 statements at the individual level, 22 at the interpersonal level, 21 in community, 51 in organizational, and 25 in policy. Our results suggest that a tiered approach, utilizing multi-level interventions instead of focusing on only one level may have the most benefit. Moreover, the policy-level influences identified by participants may be difficult to modify, thus efforts should focus on implementing evidence-based interventions to have the most meaningful impact.

An Evidence-Based Walking Program in Oregon Communities: Step It Up! Survivors.

Physical activity can help mitigate the long-term symptoms and side effects of cancer and its treatment, but most cancer survivors are not active enough to achieve these benefits. An evidence-based strategy to promote physical activity among adults is a community group-based walking program. However, many evidence-based programs do not achieve intended population health outcomes because of the challenges of real-world implementation. We used the Interactive Systems Framework for Dissemination and Implementation to conceptualize implementation of a capacity-building intervention to support delivery of a community group-based walking program. We adapted an evidence-based guide for community group-based walking programs for cancer survivors and their support network. We provided a capacity-building intervention (technical assistance and small-grant funding) and evaluated this implementation intervention. We assessed effectiveness of the intervention by measuring adoption, acceptability, appropriateness, feasibility, fidelity, implementation costs, and penetration through monthly progress reports, site visit observations, interviews, and a final report. Eight organizations received a small grant and technical assistance and implemented Step It Up! Survivors (SIUS). SIUS helped cancer survivors increase their physical activity, establish social connections, and be part of a supportive environment. Despite receiving monthly technical assistance, some grantees experienced challenges in recruiting participants, developing community partnerships, and adhering to the prescribed implementation plan. Implementation facilitators included community partners and specific components (eg, incentives for participants, webinars). Organizations needed different amounts and types of assistance with adaptation and implementation. Overall fidelity to SIUS ranged from 64% to 88%. Some integrated SIUS within existing organizational programming for sustainability. The provision of funding and technical assistance was a successful implementation intervention. Our results suggest a need to better tailor technical assistance while organizations are in the process of adapting, implementing, and sustaining an evidence-based program in their local communities.

Public perception of predictive cancer genetic testing and research in Oregon.

The potential for using widespread genetic testing to inform health care has become a viable option, particularly for heritable cancers. Yet, little is known about how to effectively communicate the benefits and risks of both personal genetic testing and participation in biorepositories that aid scientific advancements. Nationwide efforts are engaging communities in large genetic studies to better estimate the population-wide prevalence of heritable cancers but have been met with hesitance or declination to participate in some communities. To successfully engage an Oregon population in longitudinal research that includes predictive genetic testing for pathogenic or likely pathogenic variants associated with an increased risk for cancer, researchers conducted 35 focus groups (two of which were held in Spanish) in 24 of Oregon's 36 counties to better understand knowledge and attitudes related to genetic testing and willingness to participate in longitudinal genetic research. A total of 203 adults (mean = 45.6 years; range 18-88), representing a range of education levels and prior knowledge of genetic research, participated in the focus groups. The majority (85%) of participants reported personal or family diagnoses of cancer (e.g., self, family, friends). A majority (87%) also reported a strong interest in cancer genetic testing and receiving genetic information about themselves. Nearly all focus groups (94%, 33 of 35 sites) included participant discussion citing their families (e.g., children, close relatives, and extended family members) as key motivators for participation in genetic research. For example, participants reported interest in increasing personal knowledge about their own and their families' cancer risks in order to respond proactively, if a pathogenic variant was found. While most focus groups (94%, 33 of 35 sites) included participant discussion describing barriers to predictive genetic, testing such as concerns about outcomes, the desire to learn about health risks in oneself mitigated or outweighed those fears for many participants. Other commonly reported concerns were related to potential mistrust of insurance companies, researchers, or institutions, or lack of knowledge about genetics, genetic testing, or genetic research. Participants, particularly in rural areas, highlighted critical factors for research recruitment, such as trust, personal interaction, public education about genetic research, and clear communication about study goals and processes. Our statewide findings reflect that public interest in predictive cancer genetic testing and cancer genetic research can surpass lack of knowledge of the complex topics, particularly when benefits for self and family are emphasized and when study considerations are well articulated.

Sulforaphane Bioavailability and Chemopreventive Activity in Men Presenting for Biopsy of the Prostate Gland: A Randomized Controlled Trial.

Previous studies suggest compounds such as sulforaphane (SFN) derived from cruciferous vegetables may prevent prostate cancer development and progression. This study evaluated the effect of broccoli sprout extract (BSE) supplementation on blood histone deacetylase (HDAC) activity, prostate RNA gene expression, and tissue biomarkers (histone H3 lysine 18 acetylation (H3K18ac), HDAC3, HDAC6, Ki67, and p21). A total of 98 men scheduled for prostate biopsy were allocated into either BSE (200 µmol daily) or a placebo in our double-blind, randomized controlled trial. We used nonparametric tests to evaluate the differences of blood HDAC activity and prostate tissue immunohistochemistry biomarkers between treatment groups. Further, we performed RNA-Seq analysis on the prostate biopsies and identified 40 differentially expressed genes correlated with BSE treatment, including downregulation of two genes previously implicated in prostate cancer development, AMACR and ARLNC1. Although urine and plasma SFN isothiocyanates and individual SFN metabolites were statistically higher in the treatment group, our results did not show a significant difference in HDAC activity or prostate tissue biomarkers. This study indicates BSE supplementation correlates with changes in gene expression but not with several other prostate cancer biomarkers. More research is required to fully understand the chemopreventive effects of BSE supplementation on prostate cancer.

Polymorphisms in oxidative stress pathway genes and prostate cancer risk.

PURPOSE: Age-related factors including oxidative stress play an important role in prostate carcinogenesis. We hypothesize that germline single-nucleotide polymorphisms (SNPs) in oxidative stress pathway are associated with prostate cancer (PCa) risk. In this study, we aim to examine which of these SNPs is associated with PCa. METHODS: Participants included in this analyses came from the "Genetic Susceptibility, Environment and Prostate Cancer Risk Study" conducted at the Veterans Affairs Portland Health Care System. After applying exclusion criteria, 231 PCa cases and 382 prostate biopsy-negative controls who had genotyping data on twenty-two single-nucleotide polymorphisms (SNPs) in six genes (MAPK14, NRF2, CAT, GPX1, GSTP1, SOD2, and XDH) associated with oxidative stress pathway were included in the analyses. The genotyping of SNPs was conducted by the Illumina BeadXpress VeraCode platform. We investigated these SNPs in relation to overall and aggressive PCa risk using logistic regression models controlling for relevant covariates. RESULTS: One SNP in the MAPK14 (rs851023) was significantly associated with incident PCa risk. Compared to men carrying two copies of allele A, the presence of one or two copies of the G allele was associated with decreased risk of PCa [OR (95% CI) 0.19 (0.06-0.51)]. There was no statistically significant association between other SNPs in the NRF2, CAT, GPX1, GSTP1, SOD2, and XDH genes and PCa risk. CONCLUSIONS: The MAPK14 gene SNP rs851023 was associated with PCa and aggressive PCa risk after multiple comparison adjustment. Further studies in other populations or functional studies are needed to validate the finding.

Challenges of using nationally representative, population-based surveys to assess rural cancer disparities.

Population-based surveys provide important information about cancer-related health behaviors across the cancer care continuum, from prevention to survivorship, to inform cancer control efforts. These surveys can illuminate cancer disparities among specific populations, including rural communities. However, due to small rural sample sizes, varying sampling methods, and/or other study design or analytical concerns, there are challenges in using population-based surveys for rural cancer control research and practice. Our objective is three-fold. First, we examined the characterization of "rural" in four, population-based surveys commonly referenced in the literature: 1) Health Information National Trends Survey (HINTS); 2) National Health Interview Survey (NHIS); 3) Behavioral Risk Factor Surveillance System (BRFSS); and 4) Medical Expenditures Panel Survey (MEPS). Second, we identified and described the challenges of using these surveys in rural cancer studies. Third, we proposed solutions to address these challenges. We found that these surveys varied in use of rural-urban classifications, sampling methodology, and available cancer-related variables. Further, we found that accessibility of these data to non-federal researchers has changed over time. Survey data have become restricted based on small numbers (i.e., BRFSS) and have made rural-urban measures only available for analysis at Research Data Centers (i.e., NHIS and MEPS). Additionally, studies that used these surveys reported varying proportions of rural participants with noted limitations in sufficient representation of rural minorities and/or cancer survivors. In order to mitigate these challenges, we propose two solutions: 1) make rural-urban measures more accessible to non-federal researchers and 2) implement sampling approaches to oversample rural populations.

Rural-urban differences in financial burden among cancer survivors: an analysis of a nationally representative survey.

PURPOSE: Rural cancer survivors may disproportionately experience financial problems due to their cancer because of greater travel costs, higher uninsured/underinsured rates, and other factors compared to their urban counterparts. Our objective was to examine rural-urban differences in reported financial problems due to cancer using a nationally representative survey. METHODS: We used data from three iterations of the National Cancer Institute's Health Information and National Trends Survey (2012, 2014, and 2017) to identify participants who had a previous or current cancer diagnosis. Our outcome of interest was self-reported financial problems associated with cancer diagnosis and treatment. Rural-urban status was defined using 2003 Rural-Urban Continuum Codes. We calculated weighted percentages and Wald chi-square statistics to assess rural-urban differences in demographic and cancer characteristics. In multivariable logistic regression models, we examined the association between rural-urban status and other factors and financial problems, reporting the corresponding adjusted predicted probabilities. FINDINGS: Our sample included 1359 cancer survivors. Rural cancer survivors were more likely to be married, retired, and live in the Midwest or South. Over half (50.5%) of rural cancer survivors reported financial problems due to cancer compared to 38.8% of urban survivors (p = 0.02). This difference was attenuated in multivariable models, 49.3 and 38.7% in rural and urban survivors, respectively (p = 0.06). CONCLUSIONS: A higher proportion of rural survivors reported financial problems associated with their cancer diagnosis and treatment compared to urban survivors. Future research should aim to elucidate these disparities and interventions should be tested to address the cancer-related financial problems experienced by rural survivors.

Effects of ω-3 Fatty Acids and Catechins on Fatty Acid Synthase in the Prostate: A Randomized Controlled Trial.

Animal and human studies suggest fish oil and green tea may have protective effect on prostate cancer. Fatty acid synthase (FAS) has been hypothesized to be linked to chemoprotective effects of both compounds. This study evaluated the independent and joint effects of fish oil (FO) and green tea supplement (epigallocatechin-3-gallate, EGCG) on FAS and Ki-67 levels in prostate tissue. Through a double-blinded, randomized controlled trial with 2 × 2 factorial design, 89 men scheduled for repeat prostate biopsy following an initial negative prostate biopsy were randomized into either FO alone (1.9 g DHA + EPA/day), EGCG alone (600 mg/day), a combination of FO and EGCG, or placebo. We used linear mixed-effects models to test the differences of prostate tissue FAS and Ki-67 by immunohistochemistry between pre- and post-intervention within each group, as well as between treatment groups. Results did not show significant difference among treatment groups in pre-to-post-intervention changes of FAS (P = 0.69) or Ki-67 (P = 0.26). Comparing placebo group with any of the treatment groups, we did not find significant difference in FAS or Ki-67 changes (all P > 0.05). Results indicate FO or EGCG supplementation for a short duration may not be sufficient to produce biologically meaningful changes in FAS or Ki-67 levels in prostate tissue.

Associations between cruciferous vegetable intake and selected biomarkers among women scheduled for breast biopsies.

OBJECTIVE: To examine the relationship between dietary cruciferous vegetable intake and selected tumour biomarkers for histone acetylation (H3K9ac, H3K18ac, HDAC3 and HDAC6), proliferation (Ki-67) and cell-cycle regulation (p21) from breast tissue. DESIGN: The study used baseline data of women recruited to participate in a clinical trial of sulforaphane supplement. Dietary cruciferous vegetable intake was collected through a validated Arizona Cruciferous Vegetable Intake Questionnaire. Breast tissue was obtained from biopsy samples. Spearman correlations were calculated between intake of specific cruciferous vegetables and biomarkers. Tissue biomarkers were log2-transformed to obtain approximate normality. Linear regression analyses were conducted to examine associations between cruciferous vegetable intake and biomarkers adjusting for age and use of non-steroidal anti-inflammatory drugs. False discovery rate (FDR) was used to account for multiple comparisons. SETTING: Clinical trial baseline. SUBJECTS: Fifty-four women who had abnormal mammogram findings and were scheduled for breast biopsy. RESULTS: Mean intake of total cruciferous vegetables from all food sources was 81·7 (sd 57·3) g/d. Mean urinary total sulforaphane metabolites was 0·08 (sd 0·07) µm/mm creatinine. Total cruciferous vegetable intake was inversely associated with Ki-67 protein expression in breast ductal carcinoma in situ (DCIS) tissue (ß=-0·004; se=0·001; FDR q value=0·03), but not in benign or invasive ductal carcinoma (IDC) tissue. No association was found for other biomarkers measured (HDAC3, HDAC6, H3K9, H3K18 and p21) in all tissues examined (benign, DCIS and IDC). CONCLUSIONS: The present study sought to provide additional evidence for the potential role of sulforaphane in histone acetylation and cell proliferation. Here, we report that total cruciferous vegetable intake is associated with decreased cell proliferation in breast DCIS tissue.

Environmental, Behavioral, and Cultural Factors That Influence Healthy Eating in Rural Women of Childbearing Age: Findings From a PhotoVoice Study.

Despite increasing recognition of the role nutrition plays in the health of current and future generations, many women struggle to eat healthy. We used the PhotoVoice method to engage 10 rural women in identifying perceived barriers and facilitators to healthy eating in their homes and community. They took 354 photographs, selected and wrote captions for 62 images, and explored influential factors through group conversation. Using field notes and participant-generated captions, the research team categorized images into factors at the individual, relational, community/organizational, and societal levels of a socioecological model. Barriers included limited time, exposure to marketing, and the high cost of food. Facilitators included preparing food in advance and support from non-partners; opportunities to hunt, forage, and garden were also facilitators, which may be amplified in this rural environment. Nutritional interventions for rural women of childbearing age should be multi-component and focus on removing barriers at multiple socioecological levels.
