Adapting a dyadic exercise program to be culturally relevant for Hispanic men with prostate cancer using community engagement studio: a brief report.

Background: Cancer disparities exist for Hispanic men with prostate cancer and their caregivers that could be reduced through exercise. Exercising Together© is a six-month, evidence-based dyadic resistance training program that promotes teamwork between prostate cancer survivors and their spouses to improve physical, mental, and relational health outcomes. The purpose of this study was to elicit feedback and recommendations from stakeholders on the Exercising Together© intervention to inform the cultural adaptation of this program for Hispanic men with prostate cancer. Methods: We conducted a virtual Community Engagement Studio (V-CES) with community expert stakeholders representing the Hispanic and cancer care communities in Southern Arizona. The V-CES process included orientation, presentation of the research, guided discussion, and evaluation. The V-CES was audio recorded, transcribed, and rapidly analyzed to identify actionable feedback and contextual adaptations. Results: Nine stakeholders (6/9 male; 5/9 Hispanic) completed all V-CES activities. Through stakeholder engagement and feedback from the V-CES, adaptations to the original Exercising Together© intervention included: (1) inclusion of the cancer survivor's identified caregiver, who may not be a spouse; (2) availability in English and Spanish; (3) shortening the intervention to 3 months; (4) remote delivery of the intervention; and (5) incorporation of low burden procedures. Conclusion: Findings from our V-CES informed the adaptation of a culturally relevant dyadic progressive resistance training program for Hispanic men with prostate cancer and their caregivers.

Adaptation and study protocol for harvest for health together Arizona: A mentored community garden intervention for survivors of cancer.

Background: Current health behavior recommendations for skin cancer prevention, treatment, and survivorship are the same for survivors of other cancers; they include eating a healthy diet, being physically active, maintaining a healthy weight, and minimizing ultraviolet (U.V.) exposure. Few interventions exist to support health behaviors beyond U.V. exposure. We adapted Harvest for Health, a home-based mentored gardening intervention for cancer survivors, for implementation in Arizona as a community-based intervention. Methods: Stakeholder-informed adaptations for Harvest for Health Together Arizona (H4H2-AZ) included updating intervention materials to be relevant to the arid desert environment, emphasizing the importance of sun safety in cancer survivorship, and shifting from a home-based to a community-based delivery model. Participants will be enrolled in cohorts aligned with growing seasons (e.g., spring, monsoon, fall) and matched to an individual 30 ft2 community garden plot for two growing seasons (6 months). Original intervention components retained are: 1) Master Gardeners deliver the intervention providing one-to-one mentorship and 2) gardening materials and supplies provided. This pilot six-month single-arm intervention will determine feasibility, acceptability, and appropriateness of an evidence-based adapted mentored community gardening intervention for survivors of skin cancer as primary outcomes. Secondary outcomes are to explore the effects on cancer preventive health behaviors and health-related quality of life. Discussion: This pilot single-arm intervention will determine feasibility, acceptability, and appropriateness of an evidence-based adapted mentored community gardening intervention for survivors of skin cancer. If successful, the intervention could be widely implemented throughout existing Master Gardener programs and community garden networks for survivors of other cancers. Trial registration: ClinicalTrials.gov identifier: NCT05648604. Trial registered on December 13, 2022.

Assessment of Mobility Trajectories Using Wearable Inertial Sensors During Autologous Hematopoietic Cell Transplant.

OBJECTIVE: This study aimed to characterize mobility patterns using wearable inertial sensors and serial assessment across autologous hematopoietic cell transplant (autoHCT) and investigate the relation between mobility and perceived function in patients with hematologic cancer. DESIGN: Prospective longitudinal study. SETTING: Hospital adult transplant clinic followed by discharge. PARTICIPANTS: 78 patients with hematological cancer receiving autoHCT. MAIN OUTCOME MEASURES: Mobility was measured across 3 clinical phases (pretransplant, pre-engraftment, and post-engraftment) in using inertial sensors worn during prescribed performance tests in the hospital. Perceived function was assessed using validated provider-reported (Eastern Cooperative Oncology Group [ECOG] Performance Status Scale) and patient-reported [European Organization for Research and Treatment of Cancer Quality of Life Questionnaire [EORTC QLQ-C30]) measures. Trajectories of 5 selected mobility characteristics (turn duration, gait speed, stride time variability, double support time, and heel strike angle) across the clinical phases were also evaluated using piecewise linear mixed-effects models. RESULTS: Using Principal Components Analysis, 4 mobility patterns were identified pretransplant: Gait Limitation, Sagittal Sway, Coronal Sway, and Balance Control. Gait Limitation measured pretransplant was significantly inversely associated with perceived function reported by the provider- (ß = -0.11; 95% CI: -0.19, -0.02) and patient- (ß = -4.85; 95% CI: -7.72, -1.99) post-engraftment in age-adjusted linear regression models. Mobility characteristics demonstrated immediate declines early pre-engraftment with stabilization by late pre-engraftment. CONCLUSION: Patients with hematological cancer experiencing gait limitations pretransplant are likely to have worse perceived function post-engraftment. Mobility declines in early phases post-transplant and may not fully recover, indicating an opportunity for timely rehabilitation referrals. Wearable inertial sensors can be used to identify early mobility problems and patients who may be at risk for future functional decline who may be candidates for early physical rehabilitation.

Connected Community Classification (C3): Development, Validation, and Geospatial Application for Population Health Promotion and Equity.

CONTEXT: Social determinants of health (SDOH) impact population health. Leveraging community-level strengths related to SDOH through a social infrastructure perspective can optimize health behaviors and health outcomes to promote health equity. OBJECTIVE: Our aims were to develop, validate, and apply the Connected Community Classification (C3) as comprehensive community-level measure of protective SDOH and structural factors in the Four Corners states region of the United States. DESIGN: C3 was developed using an iterative principal component analysis of publicly available data mapped to 5 SDOH domains. Regional clustering of C3 by zip code tabulation area (ZCTA) was identified using spatial autocorrelation methods. MAIN OUTCOMES: In adjusted spatial autoregressive models, we analyzed the association of C3 with high-risk health behaviors and chronic disease prevalence using publicly available data for population-level estimates of fruit and vegetable intake, physical activity, obesity, smoking, alcohol use, coronary heart disease (CHD), diabetes, and cancer. RESULTS: C3 was found to be reliable and valid; a C3 value of 10 indicates communities with greater connection (high), while a value of 1 indicates communities with greater separation (low) to social infrastructure. Lower connection, as measured by C3, was significantly inversely associated with lower fruit and vegetable intake, lower physical activity, and higher rates of obesity, smoking, CHD, diabetes, and cancer. C3 was significantly positively associated with heavy alcohol use. CONCLUSIONS: These findings demonstrate that communities connected to social infrastructure have better population health outcomes. C3 captures protective community attributes and can be used in future applications to assist health researchers, practitioners, nonprofits, and policymakers to advance social connection and health equity in geographically diverse underserved regions.

Diet Quality and Epigenetic Aging in the Women's Health Initiative.

BACKGROUND: Higher diet quality scores are associated with a lower risk for many chronic diseases and all-cause mortality; however, it is unclear if diet quality is associated with aging biology. OBJECTIVE: This study aimed to examine the association between diet quality and a measure of biological aging known as epigenetic aging. DESIGN: A cross-sectional data analysis was used to examine the association between three diet quality scores based on self-reported food frequency questionnaire data and five measures of epigenetic aging based on DNA methylation (DNAm) data from peripheral blood. PARTICIPANTS/SETTING: This study included 4,500 postmenopausal women recruited from multiple sites across the United States (1993-98), aged 50 to 79 years, with food frequency questionnaire and DNAm data available from the Women's Health Initiative baseline visit. MAIN OUTCOME MEASURES: Five established epigenetic aging measures were generated from HumanMethylation450 Beadchip DNAm data, including AgeAccelHannum, AgeAccelHorvath, AgeAccelPheno, AgeAccelGrim, and DunedinPACE. STATISTICAL ANALYSES PERFORMED: Linear mixed models were used to test for associations between three diet quality scores (Healthy Eating Index, Dietary Approaches to Stop Hypertension, and alternate Mediterranean diet scores) and epigenetic aging measures, adjusted for age, race and ethnicity, education, tobacco smoking, physical activity, Women's Health Initiative substudy from which DNAm data were obtained, and DNAm-based estimates of leukocyte proportions. RESULTS: Healthy Eating Index, Dietary Approaches to Stop Hypertension, and alternate Mediterranean diet scores were all inversely associated with AgeAccelPheno, AgeAccelGrim, and DunedinPACE (P < 0.05), with the largest effects with DunedinPACE. A one standard deviation increment in diet quality scores was associated with a decrement (ß ± SE) in DunedinPACE z score of -0.097 ± 0.014 (P = 9.70 x 10-13) for Healthy Eating Index, -0.107 ± 0.014 (P = 1.53 x 10-14) for Dietary Approaches to Stop Hypertension, and -0.068 ± 0.013 (P = 2.31 x 10-07) for the alternate Mediterranean diet. CONCLUSIONS: In postmenopausal women, diet quality scores were inversely associated with DNAm-based measures of biological aging, particularly DunedinPACE.

Patient perspectives of weight stigma across the cancer continuum: A scoping review.

BACKGROUND: Weight stigma has been defined as the social devaluation and denigration of individuals because of their weight. The purpose of this scoping systematic review was to assess and understand patient experiences with weight stigma in the cancer care setting. METHODS: We conducted a systematic scoping review of studies examining shame, prejudice, bias, and stigma in relation to weight and cancer-related care using five databases: PubMed, CINAHL Plus Full Text (ProQuest), Cochrane Library, PsycINFO (EBSCO), and Scopus. Articles were uploaded into Covidence for de-duplication and screening. Included studies were peer reviewed, reported adult patient experiences in cancer-related care, and were published in English between October 2012 and February 2023. Study characteristics and key findings were abstracted and qualitatively synthesized. RESULTS: Publications meeting inclusion criteria yielded five studies (n = 113 participants). Most focused on the experiences of women (n = 4) and cancers which predominantly impact women (i.e., breast, cervical, endometrial; n = 4). All stages of the cancer continuum were included with studies examining screening (n = 2), treatment (n = 1), and post-treatment survivorship (n = 2). Weight discrimination was discussed in four studies and weight-biased stereotypes were discussed in three studies. Experiences of weight bias internalization were reported in four studies. One study described an instance of implicit weight bias. CONCLUSIONS: Limited studies examine patient experiences of weight stigma in cancer care; however, current evidence suggests that patients do experience weight stigma in cancer-related care. This review highlights critical gaps and a need for more research on the prevalence and impact of weight stigma in cancer screening and care.

A Systematic Review of Telehealth-Based Pediatric Cancer Rehabilitation Interventions on Disability.

Background: Telehealth is an emerging method which may overcome barriers to rehabilitation access for pediatric cancer survivors (aged ≤19 years). This systematic review aimed to examine telehealth-based rehabilitation interventions aimed at preventing, maintaining, or improving disability in pediatric cancer survivors. Methods: We performed systematic searches in Ovid MEDLINE, Ovid EMBASE, Cochrane Library, SCOPUS, Web of Science, and CINAHL Plus between 1994 and 2022. Eligible studies included telehealth-based interventions assessing disability outcomes in pediatric cancers. Results: Database searches identified 4,040 records. Nine unique interventions met the eligibility criteria. Telehealth delivery methods included telephone (n = 6), email (n = 3), mobile health applications (n = 3), social media (n = 3), videoconferencing (n = 2), text messaging (n = 2), active video gaming (n = 2), and websites (n = 2). Interventions focused on physical activity (n = 8) or self-management (n = 1). Outcomes assessing disability varied (n = 6). Three studies reported statistically and clinically significant results. Narrative synthesis of findings was constructed based on the Picker's principles for patient-centered care: (1) values, preferences, and needs; (2) involve family and friends; (3) coordination of care; (4) provide social support; (5) holistic well-being; and (6) information and communication. Conclusions: Telehealth-based rehabilitation interventions for pediatric cancer survivors is an emerging research area with potential to improve disability outcomes. Adequately powered trials with consistency in disability outcome measures are warranted. Additional research is needed to determine the effectiveness and best practices for telehealth-based pediatric cancer rehabilitation.

Allostatic load and risk of invasive breast cancer among postmenopausal women in the U.S.

OBJECTIVE: Allostatic load can reflect the body's response to chronic stress. However, little is known about the association between allostatic load and risk of breast cancer in postmenopausal women. This study used a large prospective cohort in the United States to examine the relationship between allostatic load and invasive breast cancer risk, and to evaluate the relationship by racial and ethnic identity and breast cancer subtypes. METHODS: Among 161,808 postmenopausal participants in Women's Health Initiative, eligible were a subsample of 27,393 postmenopausal women aged 50-79 years old, who enrolled from 1993 to 1998, had serum test biomarkers, and were followed for breast cancer incidence through February 2022. Allostatic load at enrollment was computed based on eight biomarkers from lab serum tests and a questionnaire about participants' prescription drug use. The associations between allostatic scores and risk of breast cancer (overall and by subtypes) were assessed using Cox proportional hazards models. The race and ethnic differences were examined. RESULTS: Over a median follow-up time of 17.24 years, 1722 invasive breast cancer cases were identified. High allostatic load was associated with an increased risk of breast cancer (HR = 1.36, 95%CI: 1.20, 1.54 for third tertile vs first tertile, Ptrend < 0.0001). Similar trends were found in White women and non-Hispanic women. Higher allostatic load was associated with hormone receptor-positive and HER2/Neu-negative breast cancer (HR = 1.54, 95%CI: 1.30, 1.80 for third tertile vs first tertile, Ptrend < 0.0001). CONCLUSION: In this study, we found that higher allostatic load was significantly associated with an increased risk of breast cancer in postmenopausal women.

Writing groups were formed and collaborated on this summary of the 5 key takeaways from the TREC Workshop. The 2022 TREC Workshop provided a targeted and unique networking opportunity that facilitated meaningful collaborative work addressing research and clinical needs in energetics and cancer. This report summarizes the 2022 TREC Workshop's key takeaways and future directions for innovative transdisciplinary energetics and cancer research.

Associations between perceptions of relationship quality and markers of inflammation and insulin resistance among couples coping with cancer.

Among married couples living with breast and prostate cancer, positive perceptions of relationship quality by both survivors and their spouses were associated with lower inflammation or insulin resistance in their partner. Our data support evidence that health within couples is both interdependent and transactional and suggests that one member's perception of the relationship is associated with biologic changes in one's partner, leading to better physical health of the couple. These findings may provide a biologic underpinning to observations of an inverse relationship between relational satisfaction and overall mortality and underscore the need for a dyadic approach to health. PURPOSE: Couples' health and health behaviors are intertwined, where the health of one partner can influence the health of the other but the biologic underpinnings are not known. We examined the associations between relational health and markers of inflammation and insulin resistance in couples coping with breast or prostate cancer. METHODS: Participants (90 cancer survivor-spouse dyads) completed self-report measures of relational health including Dyadic Adjustment Scale-7 (relationship quality), Dyadic Coping Inventory (communication), and shared physical activity, as well as Community Health Activities Model Program for Seniors (individual physical activity). Inflammation (C-reactive protein (CRP)) and homeostasis model assessment of insulin resistance (HOMA-IR) were measured in serum samples. Structural equation modeling including demographic and clinical covariate controls was used to estimate separate actor and partner effects of relationship quality, communication, and physical activity on CRP and HOMA-IR. RESULTS: Participants were aged 63.1 ± 10.4 years with an average relationship duration of 30.0 ± 1.1 years. Higher survivor perceived relationship quality was associated with lower spouse CRP (b = - 0.07; 95%CI: - 0.13, - 0.01), whereas higher spouse perceived relationship quality was associated with lower survivor HOMA-IR (b = - 0.07; 95%CI: - 0.13, - 0.03). There were no other significant actor or partner effects observed. CONCLUSIONS: Among cancer survivor-spouse dyads, how one member of the couple perceives the quality of the relationship impacts disease biomarkers in the other, providing preliminary evidence for biological linkage between relational health and chronic disease risk. IMPLICATIONS FOR CANCER SURVIVORS: Relationship quality may positively influence biomarkers of inflammation and insulin resistance in couples coping with breast and prostate cancer. Dyadic approaches to optimize survivorship health may be warranted. TRIAL REGISTRATION: ClinicalTrials.gov NCT03630354, 08/14/2018; Open Science Framework ( https://bit.ly/3S4rUtJ ).

Conducting Photovoice With Binational Cancer Survivors to Identify Health Behavior Change Intervention Preferences.

BACKGROUND: Culturally adapted behavior interventions are needed to support lifestyle behavior change for survivors of cancer. OBJECTIVES: To identify programming preferences of Mexicanorigin female survivors of breast cancer living on the U.S./Mexico border. METHODS: We conducted a nine-week photovoice project with survivors of breast cancer in Nogales, Sonora/Arizona exploring viewpoints on food and dietary habits, wellness activities, and preferences for healthy lifestyle intervention programming. Photovoice, a participatory qualitative research technique, provided participants with research skills to document and share their lived experience through photographs. Weekly sessions began with photograph presentations and concluded with group discussion of common themes. Data were analyzed following a thematic content analysis using session notes and written narratives compiled during discussion sessions. RESULTS: Survivors (n = 6) worked collaboratively with facilitators to identify themes related to diet and physical activity behavior. Connection between food and culture and the importance of enjoying meals with others was emphasized. Primary activity interests included leisure-time recreation that relieved anxiety related to their cancer diagnosis rather than regimented exercise routines. Participants noted the importance of giving and receiving social support and emphasized altruism to support positive mood and self-efficacy during survivorship. Networking and knowledge sharing were considered valuable. CONCLUSIONS: Our findings highlight the importance of collaborative research such as photovoice to gain insights for adaptation of evidence-based lifestyle interventions for Mexican-origin survivors of cancer. Key adaptation considerations include culturally relevant dietary preferences and patterns, physical activities with a strong mind-body component, and opportunities for social engagement and experience sharing.

Using Wearable Inertial Sensors to Assess Mobility of Patients With Hematologic Cancer and Associations With Chemotherapy-Related Symptoms Before Autologous Hematopoietic Stem Cell Transplant: Cross-sectional Study.

BACKGROUND: Wearable sensors could be a simple way to quantify and characterize mobility in patients with hematologic cancer scheduled to receive autologous hematopoietic stem cell transplant (autoHSCT) and how they may be related to common treatment-related symptoms and side effects of induction chemotherapy. OBJECTIVE: We aimed to conduct a cross-sectional study comparing mobility in patients scheduled to receive autoHSCT with that in healthy, age-matched adult controls and determine the relationships between patient mobility and chemotherapy-related symptoms. METHODS: Patients scheduled to receive autoHSCT (78/156, 50%) and controls (78/156, 50%) completed the prescribed performance tests using wearable inertial sensors to quantify mobility including turning (turn duration and number of steps), gait (gait speed, stride time, stride time variability, double support time, coronal trunk range of motion, heel strike angle, and distance traveled), and balance (coronal sway, coronal range, coronal velocity, coronal centroidal frequency, sagittal sway, sagittal range, sagittal velocity, and sagittal centroidal frequency). Patients completed the validated patient-reported questionnaires to assess symptoms common to chemotherapy: chemotherapy-induced peripheral neuropathy (Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity subscale), nausea and pain (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire), fatigue (Patient-Reported Outcomes Measurement Information System Fatigue Short Form 8a), vertigo (Vertigo Symptom Scale-short form), and depression (Center for Epidemiological Studies-Depression). Paired, 2-sided t tests were used to compare mobility between patients and controls. Stepwise multivariable linear regression models were used to evaluate associations between patient mobility and symptoms. RESULTS: Patients aged 60.3 (SD 10.3) years had significantly worse turning (turn duration; P<.001), gait (gait speed, stride time, stride time variability, double support time, heel strike angle, stride length, and distance traveled; all P<.001), and balance (coronal sway; P<.001, range; P<.001, velocity; P=.02, and frequency; P=.02; and sagittal range; P=.008) than controls. In patients, high nausea was associated with worse stride time variability (ß=.001; P=.005) and heel strike angle (ß=-.088; P=.02). Pain was associated with worse gait speed (ß=-.003; P=.003), stride time variability (ß=.012; P=.02), stride length (ß=-.002; P=.004), and distance traveled (ß=-.786; P=.005). Nausea and pain explained 17% to 33% and 14% to 36% of gait variance measured in patients, respectively. CONCLUSIONS: Patients scheduled to receive autoHSCT demonstrated worse mobility in multiple turning, gait, and balance domains compared with controls, potentially related in part to nausea and pain. Wearable inertial sensors used in the clinic setting could provide granular information about mobility before further treatment, which may in turn benefit from rehabilitation or symptom management. Future longitudinal studies are needed to better understand temporal changes in mobility and symptoms across the treatment trajectory to optimally time, design, and implement strategies, to preserve functioning in patients with hematologic cancer in the long term.

Factors associated with cancer treatment delay: a protocol for a systematic review and meta-analysis.

INTRODUCTION: Treatment delays are significantly associated with increased mortality risk among adult cancer patients; however, factors associated with these delays have not been robustly evaluated. This review and meta-analysis will evaluate factors associated with treatment delays among patients with five common cancers. METHODS AND ANALYSIS: Scientific databases including Ovid MEDLINE, Elsevier Embase, EBSCOhost CINAHL Plus Full Text, Elsevier Scopus and ProQuest Dissertations and Theses Global will be searched to identify relevant articles published between January 2000 and October 2021. Research articles published in the USA evaluating factors associated with treatment delay among breast, lung, prostate, cervical or colorectal adult cancer patients will be included. The primary outcome of the meta-analysis will be the pooled adjusted and unadjusted odds of treatment delay for patient, disease, provider and system-level factors defined according to specified time intervals. The secondary outcomes will be mean or median treatment delay for each cancer site according to first treatment and the influence of factors on the pooled mean treatment delay for each cancer site (via meta-regression analyses). Results from qualitative and mixed-methods studies will be narratively synthesised. Three reviewers will independently screen records generated from the search and two reviewers will independently extract data following a consensus agreement. Statistical heterogeneity will be assessed with a standard I2 test and funnel plots will be conducted to evaluate publication bias. Risk of bias will be assessed independently by two authors using validated tools according to the article's study design. ETHICS AND DISSEMINATION: Formal ethical approval is not required because the work is being carried out on publicly accessible studies. The findings of this review will be disseminated through a peer-reviewed scientific journal, academic conferences, social media, and key stakeholders. PROSPERO REGISTRATION NUMBER: CRD42021293131.

Health Promotion Among Mexican-Origin Survivors of Breast Cancer and Caregivers Living in the United States-Mexico Border Region: Qualitative Analysis From the Vida Plena Study.

BACKGROUND: Hispanic survivors of cancer experience increased cancer burden. Lifestyle behaviors, including diet and physical activity, may reduce the cancer burden. There is limited knowledge about the posttreatment lifestyle experiences of Hispanic survivors of cancer living on the United States-Mexico border. OBJECTIVE: This study aims to support the development of a stakeholder-informed, culturally relevant, evidence-based lifestyle intervention for Mexican-origin Hispanic survivors of cancer living in a border community to improve their dietary quality and physical activity. METHODS: Semistructured interviews with 12 Mexican-origin Hispanic survivors of breast cancer and 7 caregivers were conducted through internet-based teleconferencing. The interviews explored the impact of cancer on lifestyle and treatment-related symptoms, perception of lifestyle as an influence on health after cancer, and intervention content and delivery preferences. Interviews were analyzed using a deductive thematic approach grounded in the Quality of Cancer Survivorship Care Framework. RESULTS: Key survivor themes included perception of Mexican diet as unhealthy, need for reliable diet-related information, perceived benefits of physical activity after cancer treatment, family support for healthy lifestyles (physical and emotional), presence of cancer-related symptoms interfering with lifestyle, and financial barriers to living a healthy lifestyle. Among caregivers, key themes included effects of the cancer caregiving experience on caregivers' lifestyle and cancer-preventive behaviors and gratification in providing support to the survivors. CONCLUSIONS: The interviews revealed key considerations to the adaptation, development, and implementation of a theory-informed, evidence-based, culturally relevant lifestyle program to support lifestyle behavior change among Mexican-origin Hispanic survivors of cancer living in border communities. Our qualitative findings highlight specific strategies that can be implemented in health promotion programming aimed at encouraging cancer protective behaviors to reduce the burden of cancer and comorbidities in Mexican-origin survivors of cancer living in border communities.

The relationship between sleep and weight change among women diagnosed with breast cancer participating in the Women's Health Initiative.

PURPOSE: Short and long sleep duration and poor sleep quality are risk factors for weight gain and cancer mortality. The purpose of this study is to investigate the relationship between sleep and weight change among postmenopausal breast cancer survivors. METHODS: Women participating in the Women's Health Initiative who were diagnosed with incident breast cancer between year one and year three were included. Self-reported sleep duration was categorized as ≤ 5 h (short), 6 h, 7-8 h (optimal), and ≥ 9 h (long). Self-reported sleep quality was categorized as poor, average, and above average. Post-diagnosis weight change was the difference of weight closest to, but preceding diagnosis, and year 3 weight. We used linear regression to evaluate sleep duration and sleep quality associations with post-diagnosis weight change adjusted for potential confounders. RESULTS: Among 1156 participants, 63% were weight stable after diagnosis; average weight gain post cancer diagnosis was 3.2 kg. Six percent of women reported sleeping ≤ 5 h, 26% reported 6 h, 64% reported 7-8 h, and 4% reported ≥ 9 h. There were no differences in adjusted estimates of weight change among participants with short duration (0.37 kg; 95% CI - 0.88, 1.63), or long duration (- 0.56 kg; 95% CI - 2.03, 0.90) compared to optimal duration, nor was there a difference among poor quality (- 0.51 kg; 95% CI - 1.42, 0.41) compared to above average quality. CONCLUSION: Among postmenopausal breast cancer survivors, sleep duration and quality were not associated with weight change after breast cancer diagnosis. Future studies should consider capturing change in adiposity and to expand beyond self-reported sleep.

Relationship Between Individual Health Beliefs and Fruit and Vegetable Intake and Physical Activity Among Cancer Survivors: Results from the Health Information National Trends Survey.

Purpose: The aim of this study was to describe diet and physical activity (PA) behaviors and health beliefs among cancer survivors and identify potential differences between adolescent and young adult (AYA) and adult/older cancer survivors. Methods: Cancer survivors (n = 1864) participating in the Health Information National Trends Survey (HINTS) provided responses regarding diet and PA and selected health beliefs related to general health and cancer (self-efficacy, attitudinal belief, normative belief, risk belief, intention, and self-regulation). Health belief associations with diet and PA were assessed using adjusted logistic regression models, and multiple linear regression was used for a computed Modified American Cancer Society Adherence score (0-10, higher score indicates higher adherence to recommendations); age at diagnosis was evaluated as a potential effect modifier. Results: Health behaviors between AYA and adult/older were not significantly different; a greater percent of AYA met fruit and resistance PA recommendations. Higher health self-efficacy was associated with meeting aerobic PA recommendations (odds ratio [OR]: 1.71; confidence interval [95% CI]: 1.13-2.60; p = 0.01). Higher intention was inversely related to meeting vegetable recommendation (OR: 0.58; 95% CI: 0.35-0.97; p = 0.04). Self-regulation was associated with higher odds of meeting each recommendation. Self-efficacy and self-regulation were associated with greater adherence (ß = 0.52 ± 0.16, p = 0.001; ß = 1.21 ± 0.24, p < 0.0001, respectively). Age at diagnosis was not an effect modifier. Conclusion: Health behaviors and beliefs among AYA and adult/older are similar. Self-efficacy and self-regulation through engagement with a mobile app support adoption of diet and PA recommendations among HINTS respondents. Future interventions should consider mechanisms to promote self-efficacy and self-regulation to maximize diet and PA behaviors in cancer survivors.

A pilot feasibility study of Exercising Together© during radiation therapy for prostate cancer: a dyadic approach for patients and spouses.

INTRODUCTION: Prostate cancer can negatively impact the health of patients and their spouse, particularly early on in the cancer trajectory. PURPOSE: To determine the feasibility and acceptability of dyadic exercises during radiation therapy and preliminary efficacy on physical, mental, and relational outcomes for men and their spouses. Exercising Together©, originally designed as a 6-month dyadic resistance training program for couples post-treatment, was adapted for the radiation setting. METHODS: We conducted a single-group pilot feasibility study of Exercising Together© in men scheduled for radiation therapy for prostate cancer and their spouse. Couples attended supervised exercise sessions thrice weekly throughout radiation treatment and were followed up 8 weeks later. Primary outcomes were feasibility and acceptability with secondary outcomes of changes in physical (physical functioning (short physical performance battery (sPPB)), gait speed (m/s), functional capacity (400-m walk (min), physical activity (min/week)), mental (depressive symptoms (CES-D), and anxiety (SCL-90 ANX)), and relationship (Dyadic Coping, Role Overload, and Physical Intimacy Behavior Scales) health outcomes for each partner. Participants completed an evaluation post-intervention. RESULTS: Ten couples enrolled and 8 completed the intervention, attending 83% of scheduled sessions. Couple satisfaction with the intervention was high (patients: mean difference (MD) = 9.4 ± 1.9 and spouses: MD = 10.0 ± 0.0, on a 1-10 scale). At post-intervention, gait speed (MD = 0.1; 95%CI: 0.1, 0.2; p = 0.003; d = 0.94) and functional capacity (MD = -0.6; 95%CI: -0.9, 0.3; p = 0.002; d = -0.42) improved in patients and sPPB in spouses (MD = 1.3; 95%CI: 0.3, 2.2; p = 0.02; d = 0.71). Total physical activity increased non-significantly for patients and significantly for spouses at post-intervention and decreased at follow-up (MD = 179.6; 95%CI: 55.4, 303.7; p = 0.01; d = 1.35 and MD = -139.9; 95%CI: -266.5, 13.3; p = 0.03; d=1.06). Among patients, anxiety and active engagement significantly improved post-intervention (MD = -2.3; 95%CI: -3.8, 0.7; p = 0.01; d = -0.43 and MD = 2.5; 95%CI: 0.7, 4.3; p = 0.01; d = 0.98, respectively). There were modest effects on other physical, mental, and relationship health domains in patients and spouses. CONCLUSION: A modified version of Exercising Together© is a feasible and acceptable program during radiation therapy for prostate cancer and shows preliminary evidence for improvements on physical, mental, and relational health in both patient and spouse. A larger, fully powered randomized controlled trial is warranted and could help shift the landscape toward dyadically targeted interventions. TRIAL REGISTRATION: This study was registered on ClinicalTrials.gov on February 18th, 2018 ( NCT03418025 ).

A Protective Role for Arachidonic Acid Metabolites against Advanced Colorectal Adenoma in a Phase III Trial of Selenium.

Oxylipins derived from arachidonic acid (ARA) have been implicated in the development of colorectal adenomas and colorectal cancer. The primary purpose of this work was to determine the relationship between plasma levels of oxylipins and colorectal adenoma characteristics at study entry, as well as with the development of a new adenoma during follow-up within a Phase III adenoma prevention clinical trial with selenium (Sel). Secondarily, we sought to determine whether the selenium intervention influenced plasma oxylipin levels. Four oxylipins were quantified in stored plasma samples from a subset of Sel study subjects (n = 256) at baseline and at 12-months. There were significantly lower odds of an advanced adenoma at baseline with higher prostaglandin E2 (PGE2), with an OR (95% CI) of 0.55 (0.33-0.92), and with 5-hydroxyeicosatetraenoic acid (5-HETE) ((0.53 (0.33-0.94)); and of a large adenoma with higher PGE2 ((0.52 (0.31-0.87)). In contrast, no associations were observed between any oxylipin and the development of a new adenoma during follow-up. Selenium supplementation was associated with a significantly smaller increase in 5-HETE after 12 months compared to the placebo, though no other results were statistically significant. The ARA-derived oxylipins may have a role in the progression of non-advanced adenoma to advanced, but not with the development of a new adenoma.

Interventions for Loneliness Among Adult Cancer Survivors: A Systematic Review and Meta-Analysis.

Problem identification: Loneliness is common after cancer, contributing to poor outcomes. Interventions to modify loneliness are needed. This systematic review describes the current literature regarding loneliness interventions in cancer survivors.Literature search: Databases including: Ovid/MEDLINE; The Cochrane Central Register of Controlled Trials (CENTRAL); Elsevier/Embase; Clarivate/Web of Science (Core Collection), EBSCO/PsycINFO, EBSCO/CINAHL were used to perform a systematic review of literature using PRISMA guidelines. Second, risk of bias, meta-analysis and a narrative synthesis approach was completed to synthesize findings from multiple studies.Data evaluation/synthesis: Six thousand five hundred three studies were initially evaluated; eight studies met inclusion criteria. Findings indicate a paucity of interventions, generally of lower quality. Interventions were feasible and acceptable; those interventions with cultural modifications were more likely to demonstrate effectiveness.Conclusions: There are limited interventions addressing loneliness in cancer survivors. Development and testing of culturally-relevant programs are warranted.Implications for psychosocial oncology: Current studies suggest the psychosocial symptom of loneliness is modifiable among adult cancer survivors. Few interventions have been tested and shown to be effectiveness in cancer survivors in the U.S. and none have been tailored for older adult survivors, by patient gender/sex and few for specific race/ethnic groups. Results from this systematic review: a narrative synthesis and meta-analysis can inform future interventions targeting loneliness in this growing, yet vulnerable, adult cancer survivor population.
