Longitudinal Transition of Symptom Cluster Profiles Among Community-Dwelling Older Adults With Heart Failure.

BACKGROUND: Older adults with heart failure experience clustered symptoms. However, little is known about how symptom clusters transition over time. OBJECTIVES: This study aimed to (1) identify the longitudinal transition of symptom cluster profiles over 8 years and (2) examine the associations between demographic and clinical factors and the transition between symptom cluster profiles over time. METHODS: We conducted a longitudinal secondary analysis of data from the Health and Retirement Study's 2008, 2012, and 2016 surveys. We included participants with heart failure in the core data sets and their proxy respondents in the exit data sets. We included demographic and clinical variables as well as six symptoms (fatigue, shortness of breath, pain, swelling, depressive symptoms, dizziness) through physical health interviews. We used latent transition analysis and multinominal regressions to determine longitudinal profiles and explored the association between demographic and clinical factors and membership in symptom cluster profiles. RESULTS: Among 690 participants, we found four symptom cluster profiles (high burden, low burden, distressing, and respiratory-depressive distress). Participants in the low burden at baseline had the highest probability of transitioning to the respiratory-depressive distress profile. Participants in the respiratory-depressive distress at 4 years had the highest probability of transitioning to the high burden profile. Male sex, Black/African American race, smoking, and comorbidities were associated with the increased odds of transiting from the low symptom burden to the high symptom burden profile. DISCUSSION: Symptom cluster profile memberships were stable over an 8-year period. However, symptom cluster profiles are changeable and deteriorate over time. Identifying predictive factors enables targeted interventions for those at highest risk.

Chronic Illness Perceptions and Cardiovascular Disease Risk Behaviors in Black and Latinx Sexual Minority Men with HIV: A Cross-Sectional Analysis.

Ethnic and racial sexual minority men with HIV have a disproportionately higher risk of HIV-related cardiovascular disease (CVD). There is a lack of tailored and culturally salient behavioral interventions to address HIV-related chronic illness in ethnic and racial sexual minority men, and literature on their understanding and awareness of modifiable behavioral risks is limited. The purpose of this study was to assess illness perceptions about HIV and HTN, and describe physical activity, tobacco, and e-cigarette use in Black and Latinx sexual minority men living with HIV. We used the validated Illness Perception Questionnaire-Revised (IPQ-R) to assess perceptions about two interrelated chronic diseases, HIV and CVD. To assess CVD behavioral risk, we assessed physical activity using the International Physical Activity Questionnaire. Tobacco and e-cigarette use were assessed using items from the Behavioral Risk Factor Surveillance System. Sleep difficulties were the most prevalent symptom attributed to HIV, and were statistically associated with fatigue, upset stomach, and loss of strength. Anxiety was reported to be caused by HIV (57%) and HTN (39%). Half of the participants engaged in vigorous activity for 128 min (SD = 135) daily, and 63% engaged in moderate activity for 94 min (SD = 88) daily. Over a third reported current tobacco use and 20% reported current e-cigarette use. This study provides formative data to better understand how Black and Latinx sexual minority men with HIV perceive intersecting chronic illnesses and their engagement in modifiable CVD risk behaviors. Sleep, mental health disparities, and financial hardships were commonly reported. More research is needed to address intersecting chronic illnesses and mental health conditions that are influenced by social positioning over the life course, and impact CVD risk factors. This study was not registered.

Association between adverse childhood experiences and self-reported health-risk behaviors among cancer survivors: A population-based study.

AIMS: Existing evidence shows that people who report Adverse Childhood Experiences (ACEs) are more likely to exhibit health-risk behaviors. However, limited research on this topic pertains to oncology population. We aim to address this knowledge gap by estimating the prevalence of ACEs and investigating their association with self-reported health-risk behaviors among adult cancer survivors living in the U.S. METHODS: We conducted a secondary analysis using cross-sectional data from the 2021 Behavioral Risk Factor Surveillance System ACE module. We included 4,126 adults, aged ≥18 years, with a history of cancer. The outcome variable was self-reported health-risk behaviors, which included cigarette smoking, e-cigarette use, and binge alcohol drinking. Self-reported ACEs history was the primary independent variable, comprised of 11 questions regarding child abuse and dysfunctional households. We conducted descriptive statistics and multivariable logistic regression to describe the relationship between the ACE history and health-risk behaviors. RESULTS: Overall, 84.2% of cancer survivors self-reported as White, 58.4% were women, and 76.6% were aged 65+ years. Nearly two-thirds of the sample (63.2%) self-reported at least one ACE (prior to age 18) and 21.7% engaged in ≥1 health-risk-behaviors, such as cigarette smoking, binge alcohol drinking, or e-cigarette use. Experiencing ≥3 ACEs was associated with 145% increased odds of reporting at least one health-risk behavior (OR = 2.45, 95% CI [1.78-3.38]) when compared to those without a history of ACEs. Besides, survivors who were younger, divorced, less educated, and had low income had higher odds of reporting at least one health-risk behavior. CONCLUSIONS: Overall, a history of ACEs is associated with health-risk behaviors. These all can negatively impact cancer survivors' overall well-being. Early screening for ACE during oncologic visits can be a protective measure for preventing health-risk behaviors among cancer survivors.

Longitudinal associations among physical activity, inflammatory markers, and quality of life in patients with head and neck cancer.

INTRODUCTION: The aim of this study was to explore the associations among physical activity (PA), inflammatory markers, and quality of life (QoL) from preradiotherapy to 1-year postradiotherapy for patients with head and neck cancer (HNC). METHODS: This was an observational longitudinal study. Mixed-effect models incorporating within-subject correlation were used to examine the relationship among the three key variables. RESULTS: Aerobically active patients had significantly lower levels of sTNFR2 (but not other inflammatory markers) than aerobically inactive patients. Being aerobically active and lower inflammation were independently associated with better total QoL scores after adjusting covariates. The trend was similar for patients engaged in strength exercises. CONCLUSIONS: Being aerobically active was associated with lower inflammation as represented by sTNFR2 but not with other inflammatory markers. Higher PA (aerobic and strength) and lower inflammation were linked to better QoL. More research is warranted to validate the association among PA, inflammation, and QoL.

Measurement invariance of the 10-item resilience scale specific to cancer in Americans and Chinese: A propensity score-based multidimensional item response theory analysis.

Objective: Little is known about the measurement invariance (MI) of resilience instruments in cancer care. This study was designed to examine MI of 10-Item Resilience Scale (RS-SC-10) in Americans and Chinese with cancer using propensity score-based multidimensional item response theory (MIRT) analysis. Methods: A sample of 924 patients were enrolled in the Be Resilient to Cancer trial involving 1 hospital in America and 3 hospitals in China. Data were collected from the RS-SC-10 and Hospital Anxiety and Depression Scale. Propensity score matching and MIRT were performed to evaluate Differential Item Function. Integrated Discrimination Improvement and Net Reclassification Improvement were used to indirectly estimate the MI through incremental prediction ability of MIRT-based score over total score. Results: RS-SC-10 retained 10 items with monotonous thresholds and its original two-factor structure. Nonuniform Differential Item Function was recognized in Item 4 (P â€‹= â€‹0.0011, Δ%ß1 â€‹= â€‹4.15%) and Item 8 (P â€‹= â€‹0.0017, Δ%ß1 â€‹= â€‹5.99%). Net Reclassification Improvement ranged from 9.04% to 35.01%, and Integrated Discrimination Improvement ranged from 8.82% to 20.60%. Conclusions: Although partial MI has been identified between Americans and Chinese, RS-SC-10 remains a critical indicator to emotional distress in cancer care.

Association between social connectedness and stress or anxiety among older cancer survivors during the 2020-2021 winter surge of the COVID-19 pandemic.

INTRODUCTION: Our goal was to estimate a relative decreased rate of social connectedness to family and friends, increased rate of stress or anxiety during the 2020-2021 winter surge of the COVID-19 pandemic, and investigate the association between social connectedness and stress or anxiety among a nationally representative sample of older adults with cancer history. MATERIALS AND METHODS: We used population-based, nationally representative cross-sectional data from the Medicare Current Beneficiary Survey COVID-19 Winter 2021 Community Supplement. The study cohort included community-living Medicare beneficiaries aged 65 years and older who self-reported cancer history (other than skin cancer) (n = 1650). Sample weights were applied to account for the complex survey design, with results generalizable to 8.5 million Medicare beneficiaries with cancer history. The outcome was self-reported feelings of stress or anxiety during the 2020-2021 winter surge of the COVID-19 pandemic. The independent variable was social connectedness, defined as feeling less socially connected to family and friends during the 2020-2021 winter surge of the COVID-19 pandemic. We conducted weighted descriptive statistics and multivariable logistic regression analyses. RESULTS: Overall, 42.5% of beneficiaries reported decreased social connectedness to family and friends, and 37.8% reported increased feelings of stress or anxiety during the 2020-2021 winter surge of the COVID-19 pandemic. After adjusting for all covariates, participants who reported decreased social connectedness had 154% higher odds of increased feelings of stress or anxiety (adjusted odds ratio [AOD] = 2.54, 95% confidence interval [CI] = 2.00-3.20, p ≤0.001) compared to those who reported more or about the same social connectedness to family and friends. The odds of increased feelings of stress or anxiety were also higher for those who self-reported as Hispanic vs. non-Hispanic White beneficiaries (AOR = 1.35, 95% CI = 1.10-1.73, p = .016), women vs. men (AOR = 1.85, 95%CI = 1.43-2.38, p ≤0.001), and those who reported depression history vs. not reporting depression history (AOR = 2.55, 95% CI = 1.86-3.48, p ≤0.000). DISCUSSION: An estimated 3.6 million older adults with cancer history reported decreased social connectedness to family and friends, and 3.2 million reported increased feelings of stress or anxiety during the 2020-2021 winter surge of the COVID-19 pandemic. Identifying these adults and referring them to appropriate supportive care resources and services are essential to help them cope with negative feelings.

Integrating Palliative Care Into Self-management of Breast Cancer: A Pilot Randomized Controlled Trial.

BACKGROUND: Breast cancer patients may not be well-informed about palliative care, hindering its integration into cancer self-management. OBJECTIVE: The aim of this study was to test Managing Cancer Care: A Personal Guide (MCC-PT), an intervention to improve palliative care literacy and cancer self-management. METHODS: This was a single-blind pilot randomized controlled trial to evaluate the feasibility/acceptability and intervention effects of MCC-PT on palliative care literacy, self-management behaviors/emotions, and moderation by demographic/clinical characteristics. We enrolled 71 stages I to IV breast cancer patients aged at least 21 years, with >6-month prognosis at an academic cancer center. Patients were randomized to MCC-PT (n = 32) versus symptom management education as attention-control (n = 39). At baseline, 1 month, and 3 months, participants completed the Knowledge of Care Options Test (primary outcome), Control Preferences Scale, Goals of Care Form, Medical Communication Competence Scale, Measurement of Transitions in Cancer Scale, Chronic Disease Self-efficacy Scale, Hospital Anxiety and Depression Scale, and the Mishel Uncertainty in Illness Scale. RESULTS: Mean participant age was 51.5 years (range, 28-74 years); 53.5% were racial/ethnic minority patients, and 40.8% had stage III/IV cancer. After adjusting for race/ethnicity, MCC-PT users improved their palliative care literacy with a large effect size (partial η2 = 0.13). Patients at late stage of disease showed increased self-management (partial η2 = 0.05) and reduced anxiety (partial η2 = 0.05) and depression (partial η2 = 0.07) with medium effect sizes. CONCLUSIONS: Managing Cancer Care: A Personal Guide is feasible and appears most effective in late-stage cancer. Research is needed to elucidate relationships among cancer stage, race/ethnicity, and self-management outcomes. IMPLICATIONS FOR PRACTICE: Integration of palliative care into cancer care can assist in creation of appropriate self-management plans and improve emotional outcomes.

Improving Breast Cancer Family Caregivers' Palliative Care Literacy: A Pilot Randomized Trial.

Self- and family management (SFM) refers to patients' and family caregivers' activities to co-manage illness. Two barriers to SFM are low palliative care literacy and lack of goals of care communication, which potentially result in SFM activities that are unsupportive of patients' goals. Managing Cancer Care: A Caregiver's Guide (MCC-CG) aims to improve palliative care literacy and communication within a SFM training program. In this pilot randomized trial, we enrolled breast cancer family caregivers and collected data at 0, 1, and 3 months on palliative care literacy, SFM engagement, communication, transitions management, uncertainty, caregiver burden, and caregiver competence/personal gain. Participants (n = 35) had a mean age of 54 (range: 18-81) and were 66% white and 34% racial/ethnic minorities. Intervention participants improved their palliative care literacy and SFM engagement, reduced uncertainty and caregiver burden, increased competence/personal gain, and had more goals of care conversations over time. MCC-CG has preliminary efficacy, warranting further study.

Racial and Ethnic Variation in COVID-19 Vaccination Uptake Among Medicare Beneficiaries with Cancer History.

BACKGROUND: The purpose of this study was to estimate COVID-19 vaccination rate among Medicare beneficiaries with cancer history and determine whether COVID-19 vaccine uptake is higher among non-Hispanic White beneficiaries compared with racially and ethnically minoritized beneficiaries. METHODS: We used US representative, cross-sectional data from the Medicare Current Beneficiary Survey COVID-19 Winter 2021 Rapid Response Community Supplement Survey. A total of 1,863 respondents with self-reported cancer history (other than skin cancer) were included. The outcome was self-reported receipt of at least one coronavirus vaccine dose since vaccines became available. The key independent variable of interest was self-reported race and ethnicity. We applied sample weights to account for the survey design and provide population estimates to 9.6 million beneficiaries with cancer history. Weighted descriptive statistics and multivariable logistic regression analyses were conducted. RESULTS: During the first 4 months of vaccine availability, 69.6% of beneficiaries received at least one vaccine dose of which 65.4% had two vaccine doses. A larger proportion of non-Hispanic White beneficiaries (71.9%) had at least one vaccine dose compared with non-Hispanic Black (60.4%) and Hispanic (57.4%) beneficiaries. An estimated 30.4% of beneficiaries were still unvaccinated, that represents approximately 2.9 million unvaccinated beneficiaries with cancer history. Hispanic beneficiaries were 42% (OR: 0.58; 95% CI: 0.33-0.99; p = .048) less likely to be vaccinated compared with non-Hispanic White beneficiaries. CONCLUSIONS: Results indicate racial and ethnic differences in vaccine uptake among Medicare beneficiaries with cancer history. Effective strategies are needed to help increase vaccine confidence and uptake among adults with cancer history.

Factors associated with sleep health in young women after breast cancer treatment.

Young women with breast cancer (YWBC) report physical and psychological symptom distress after therapy but little is known about their sleep health. The purpose of this study was to identify sociodemographic, clinical, and psychosocial factors associated with sleep health and assess the potential role of appraisal of illness and coping on sleep health. An adapted cognitive appraisal and coping conceptual framework guided the study. We used a cross-sectional design with 159 women who were diagnosed with stage I-III breast cancer ≤50 years old. Sleep health was measured by the Pittsburgh Sleep Quality Index (PSQI). The mean age was 43.6 years (SD = 6.8), the majority of whom were non-Hispanic White (84%) and completed chemotherapy or radiotherapy (>70%). More than half of participants (55%) reported poor sleep health (PSQI > 8), and those with worse family functioning and from a racial/ethnic minority group were significantly more likely to have poor sleep health. Cognitive appraisal had a minimal mediation effect for anxiety on sleep health, and coping did not mediate the effect of any psychosocial variables on sleep health. Poor sleep health is a significant clinical problem in YWBC. Further research is needed to explore sleep health disparities among diverse cancer survivors and to examine sleep health in the context of family. Sleep assessment, management, and appropriate referrals to sleep providers should be part of routine survivorship care.

Epigenetic age acceleration, fatigue, and inflammation in patients undergoing radiation therapy for head and neck cancer: A longitudinal study.

BACKGROUND: The authors measured epigenetic age acceleration (EAA) during and after cancer treatment and its association with inflammation and fatigue, which is a debilitating symptom in patients with cancer. METHODS: Patients who had head and neck cancer without distant metastases were assessed before, immediately after, and at 6 months and 12 months postradiotherapy. Blood DNA methylation was assessed using a proprietary bead chip (the Illumina MethylationEPIC BeadChip). EAA was calculated using the Levine epigenetic clock (DNAmPhenoAge), adjusted for chronological age. Fatigue was assessed using the Multidimensional Fatigue Inventory-20. Inflammatory markers were measured using standard techniques. RESULTS: Most patients (N = 133) were men, White, had advanced disease, and received concurrent chemoradiation. EAA changes over time were significant, with the largest increase (4.9 years) observed immediately after radiotherapy (P < .001). Increased EAA was associated with elevated fatigue (P = .003) over time, and patients who had severe fatigue experienced 3.1 years higher EAA than those who had low fatigue (P < .001), which was more prominent (5.6 years; P = .018) for patients who had human papillomavirus-unrelated disease at 12 months posttreatment. EAA was also positively associated with inflammatory markers, including C-reactive protein (CRP) and interleukin-6 (IL-6), over time (P < .001), and patients who had high CRP and IL-6 levels exhibited increases of 4.6 and 5.9 years, respectively, in EAA compared with those who had low CRP and IL-6 levels (P < .001). CRP and IL-6 mediated the association between EAA and fatigue (CRP: 95% CI, 0.060-0.279; IL-6: 95% CI, 0.024-0.220). CONCLUSIONS: Patients with head and neck cancer experienced increased EAA, especially immediately after treatment completion. EAA was associated with greater fatigue and inflammation, including 1 year after treatment. Inflammation may be a target to reduce the impact of age acceleration on poor functional outcomes.

Association of Epigenetic Age Acceleration With Risk Factors, Survival, and Quality of Life in Patients With Head and Neck Cancer.

PURPOSE: Epigenetic age acceleration (EAA) is robustly linked with mortality and morbidity. This study examined risk factors of EAA and its association with overall survival (OS), progression-free survival (PFS), and quality of life (QOL) in patients with head and neck cancer (HNC) receiving radiation therapy. METHODS AND MATERIALS: Patients without distant metastasis were enrolled and followed before and at the end of radiation therapy and at 6 and 12 months after radiation therapy. EAA was calculated with DNAmPhenoAge at all 4 time points. Risk factors included demographic characteristics, lifestyle, clinical characteristics, treatment-related symptoms, and blood biomarkers. Survival data were collected until August 2020, and QOL was measured using Functional Assessment of Cancer Therapy-HNC. RESULTS: Increased comorbidity, symptoms unrelated to human papilloma virus, and more severe treatment-related symptoms were associated with higher EAA (P = .03 to P < .001). A nonlinear association (quadratic) between body mass index (BMI) and EAA was observed: decreased BMI (<35 kg/m2; P = .04) and increased BMI (≥35 kg/m2; P = .01) were linked to higher EAA. Increased EAA (per year) was associated with worse OS (hazard ratio [HR], 1.11 [95% confidence interval {CI}, 1.03-1.18; P = .004]; HR, 1.10 [95% CI, 1.01-1.19; P = .02] for EAA at 6 and 12 months after treatment, respectively) and PFS (HR, 1.10 [95% CI, 1.02-1.19; P = .02]; HR, 1.14 [95% CI, 1.06-1.23; P < .001]; and HR, 1.08 [95% CI, 1.02-1.14; P = .01]) for EAA before, immediately after, and 6 months after radiation therapy, respectively) and QOL over time (ß = -0.61; P = .001). An average of 3.25 to 3.33 years of age acceleration across time, which was responsible for 33% to 44% higher HRs of OS and PFS, was observed in those who died or developed recurrence compared with those who did not (all P < .001). CONCLUSIONS: Compared with demographic and lifestyle factors, clinical characteristics were more likely to contribute to faster biological aging in patients with HNC. Acceleration in epigenetic age resulted in more aggressive adverse events, including OS and PFS. EAA could be considered as a marker for cancer outcomes, and decelerating aging could improve survival and QOL.

Mediating roles of psychological factors and physical and social environments between socioeconomic status and dietary behaviors among African Americans with overweight or obesity.

The study aim was to examine the relationship between socioeconomic status (SES) and dietary behaviors through psychological and environmental mediators among African Americans with overweight or obesity. We conducted a cross-sectional study in 225 African American men and women. Data were analyzed using structural equation modeling with bootstrapping procedures. In the multiple mediation model, SES had a significant indirect effect on dietary behaviors through psychological and environmental factors (ß = -.27; p = .01; 95% confidence interval [CI] = -0.59--0.10), but it had no significant direct effect on dietary behaviors (ß = .06; p = .70; 95% CI = -0.21-0.39). SES had significant direct effects on psychological (ß = .52; p = .01; 95% CI = 0.31-0.77) and environmental factors (ß = -.40; p = .03; 95% CI = -0.53--0.25). Psychological (ß = -.31; p = .02; 95% CI = -0.68--0.04) and environmental factors (ß = .26; p = .01; 95% CI = 0.04-0.47) also showed significant direct effects on dietary behaviors. Thus, psychological and environmental factors mediated the relationship between SES and dietary behaviors in African Americans with overweight or obesity. Interventions that enhance psychological and environmental factors such as self-efficacy, perceived barriers to healthy eating, health perceptions, and physical and social environments may improve dietary behaviors among socioeconomically disadvantaged African Americans.

The role of the gut microbiome in cancer-related fatigue: pilot study on epigenetic mechanisms.

PURPOSE: Recent evidence supports a key role of gut microbiome in brain health. We conducted a pilot study to assess associations of gut microbiome with cancer-related fatigue and explore the associations with DNA methylation changes. METHODS: Self-reported Multidimensional Fatigue Inventory and stool samples were collected at pre-radiotherapy and one-month post-radiotherapy in patients with head and neck cancer. Gut microbiome data were obtained by sequencing the 16S ribosomal ribonucleic acid gene. DNA methylation changes in the blood were assessed using Illumina Methylation EPIC BeadChip. RESULTS: We observed significantly different gut microbiota patterns among patients with high vs. low fatigue across time. This pattern was characterized by low relative abundance in short-chain fatty acid-producing taxa (family Ruminococcaceae, genera Subdoligranulum and Faecalibacterium; all p < 0.05), with high abundance in taxa associated with inflammation (genera Family XIII AD3011 and Erysipelatoclostridium; all p < 0.05) for high-fatigue group. We identified nine KEGG Orthology pathways significantly different between high- vs. low-fatigue groups over time (all p < 0.001), including pathways related to fatty acid synthesis and oxidation, inflammation, and brain function. Gene set enrichment analysis (GSEA) was performed on the top differentially methylated CpG sites that were associated with the taxa and fatigue. All biological processes from the GSEA were related to immune responses and inflammation (FDR < 0.05). CONCLUSIONS: Our results suggest different patterns of the gut microbiota in cancer patients with high vs. low fatigue. Results from functional pathways and DNA methylation analyses indicate that inflammation is likely to be the major driver in the gut-brain axis for cancer-related fatigue.

Pilot study of combined aerobic and resistance exercise on fatigue for patients with head and neck cancer: Inflammatory and epigenetic changes.

This pilot study examined whether a combined aerobic resistance exercise program reduced fatigue and the potential inflammatory and epigenetic mechanisms in patients with head and neck cancer (HNC) receiving intensity-modulated radiotherapy. The exercise group (N = 12) received a 3-month supervised aerobic resistance exercise intervention that was initiated before a 6-week radiotherapy regimen; the control group (N = 14) received standard care. Fatigue was measured using Multidimensional Fatigue Inventory-20; physical function measures included a 6-minute walk distance (6MWD), chair stands, bicep curls, and hand grip strength. Inflammatory markers and DNA methylation data were acquired using standardized protocol. Patients were mostly white (93%) and male (81%) with a mean age of 57 years. At the end of the intervention, the exercise group had a marginal decrease in fatigue compared with the control (-5.0 vs. 4.9; P = 0.10). The exercise group had a significantly greater improvement in 6MWD (29.8 vs. -55.5 m; P = 0.04), and a marginally smaller decline in hand grip (-0.3 vs. -5.8 lbs; P = 0.05) at the end of the intervention than the control. No significant difference in inflammatory markers was observed between groups. Lower plasma interleukin (IL) 6, IL1 receptor antagonist, tumor necrosis factor α (TNFα), soluble TNF receptor II and C-reactive protein were significantly associated with increased 6MWD, chair stand, and bicep curl at the end of the intervention (p < 0.05). Among the 1152 differentially methylated sites (DMS) after intervention (p < 0.001), 163 DMS were located in gene promoter regions. Enrichment analysis suggested that the top 10 upstream regulators were associated with tumor (HNF4A, RPP38, HOXA9, SAHM1, CDK7, NDN, RPS15) and inflammation (IRF7, CRKL, ONECUT1). The top 5 diseases or functions annotations of the 62 hypermethylated DMS indicated anti-tumor and anti-inflammatory effects that might be linked to exercise. These findings suggest that exercise may improve physical performance and reduce fatigue, which could be further linked to decreased inflammation, during active radiotherapy for HNC patients. Larger studies are warranted.

Role of Sleep Duration in the Association Between Socioecological Protective Factors and Health Risk Behaviors in Adolescents.

OBJECTIVE: The purpose of this study was to examine the associations of sleep duration and socioecological protective factors with patterns of adolescent risk behaviors in Fairfax County, VA-one of the largest public school districts in the United States. METHODS: A total of 21,360 and 20,330 students in 10th and 12th grades who completed the Youth Risk Behavior Survey were included in this cross-sectional analysis. Sleep duration was measured by self-report of the average number of hours of sleep on a school night. Ten socioecological protective factors included peer-individual, family, school, and community domains. Latent class analysis was used to classify 7 risk behaviors (alcohol use, cigarette use, illicit drug use, inappropriate prescription drug use, risky sexual behavior, deviant behavior, and academic failure) into 4 class memberships (low, some, moderate, and high). Multinomial regression models were adjusted for age, sex, and race. RESULTS: Adolescents who reported sleeping the recommended 8 to 9 hours were significantly less likely to belong to the class memberships of greater risk behaviors compared with those who reported short and long sleep duration after controlling for age, sex, race, and survey year. There was a significant inverse relationship between the number of socioecological protective factors and risk behaviors for both 10th and 12th graders. Potential risks of age, sex, and race on risk behaviors were observed. No significant interaction between sleep duration and protective factors was found in either grade. CONCLUSION: This study highlights the significant associations between sleep duration and risk behaviors in adolescents with diverse socioecological protective factors. Prioritization of prevention-focused resources should consider sleep duration in addition to the socioecological protective factors commonly cited in the literature when addressing adolescent risk behaviors.

Metabolic Syndrome, Exercise, and Cardiovascular Fitness in Breast Cancer Survivors.

Comorbid illness contributes to poorer cancer outcomes and higher mortality. Metabolic syndrome (MetS) includes a cluster of risk factors that are associated with an increased risk of comorbidities. Routine physical activity represents a risk reduction strategy for cancer survivors. From 148 participants in a 12-month randomized control trial (RCT) of a fitness center exercise intervention compared to home physical activity group, a subset analysis was conducted to explore the effect of exercise on MetS risk factors. There were 32 (21.6%) breast cancer survivors who met the criteria for MetS at baseline. Over the 12 months, there were significantly fewer participants who met the criteria for MetS (p < .01), and there was significant improvement in individual risk factors, specifically fasting blood sugar (p = .01), and high-density lipoprotein (HDL; p = .02). Cardiovascular fitness was evaluated and greater heart recovery rate (HRR) was negatively associated with waist circumference, triglycerides, systolic blood pressure, fasting blood sugar, and MetS risk (p < .02) and positively associated with HDL (p = .03). Oncology advanced practitioners are uniquely qualified to integrate risk reduction into the management of at-risk oncology patients.

Endocrine Therapy-Related Symptoms and Quality of Life in Female Cancer Survivors in the Yale Fitness Intervention Trial.

PURPOSE: The aim of the current study was to describe and compare endocrine therapy-related symptoms and quality of life in female cancer survivors taking aromatase inhibitors, tamoxifen, and no endocrine therapy, and to evaluate the effect of an exercise intervention on these symptoms and quality of life. DESIGN: Randomized controlled trial. An aerobic resistance exercise intervention group was compared with a home-based exercise control group over 1 year. The exercise intervention was supervised for the first 6 months, followed by 6 unsupervised months. METHODS: Perimenopausal and early postmenopausal female cancer survivors within 3 years of completing primary or adjuvant chemotherapy were selected. A total of 154 women were enrolled in the study. Type of endocrine or hormonal therapy was documented. Symptoms were measured by the Breast Cancer Prevention Trial Symptom Checklist and the Functional Assessment of Cancer Therapy-Endocrine Subscale. Quality of life was measured by the Functional Assessment of Cancer Therapy-General. Data were collected at baseline, and at 6 and 12 months. FINDINGS: Participants generally had mild symptom distress. There was no difference in symptoms by endocrine therapy group or by exercise group. Participants taking aromatase inhibitors in the aerobic resistance exercise intervention group reported significant improvement in social, family, and functional well-being and better quality of life compared to those in the control group at 6 months but not at 12 months. CONCLUSIONS: Findings were similar to those of previous large clinical trials in that no significant differences were found for endocrine therapy-related symptoms and quality of life by type of endocrine therapy taken. However, exercise may improve quality of life outcomes for women taking aromatase inhibitors. CLINICAL RELEVANCE: Exercise has established efficacy for patient outcomes such as cardiovascular fitness, fatigue, weight management, and quality of life and may provide better quality of life for women who take aromatase inhibitors as adjuvant therapy.

Latent Transition Analysis of the Symptom Experience of Cancer Patients Undergoing Chemotherapy.

BACKGROUND: Symptom clusters reflect the person's experience of multiple cooccurring symptoms. Although a variety of statistical methods are available to address the clustering of symptoms, latent transition analysis (LTA) characterizes patient membership in classes defined by the symptom experience and captures changes in class membership over time. OBJECTIVES: The purposes of this article are to demonstrate the application of LTA to cancer symptom data and to discuss the advantages and disadvantages of LTA relative to other methods of managing and interpreting data on multiple symptoms. METHODS: Data from a total of 495 adult cancer patients who participated in randomized clinical trials of two symptom management interventions were analyzed. Eight cancer- and treatment-related symptoms reflected the symptom experience. Latent transition analysis was employed to identify symptom classes and evaluate changes in symptom class membership from baseline to the end of the interventions. RESULTS: Three classes, "A (mild symptoms)," "B (physical symptoms)," and "C (physical and emotional symptoms)," were identified. Class A patients had less comorbidity, better physical and emotional role effect, and better physical function than the other classes did. The number of symptoms, general health perceptions, and social functioning were significantly different across the three classes and were poorest in Class C. Emotional role functioning was poorest in Class C. Older adults were more likely to be in Class B than younger adults were. Younger adults were more likely to be in Class C (p < .01). Among patients in Class C at baseline, 41.8% and 29.0%, respectively, transitioned to Classes A and B at the end of the interventions. DISCUSSION: These results demonstrate that symptom class membership characterizes differences in the patient symptom experience, function, and quality of life. Changes in class membership represent longitudinal changes in the course of symptom management. Latent class analysis overcomes the problem of multiple statistical testing that separately addresses each symptom.

Adherence to American Cancer Society Guidelines on Nutrition and Physical Activity in Female Cancer Survivors: Results From a Randomized Controlled Trial (Yale Fitness Intervention Trial).

BACKGROUND: The American Cancer Society (ACS) publishes guidelines on nutrition and physical activity to minimize health risks in cancer patients and survivors. Studies show that high adherence to such guidelines is associated with a decrease in overall cancer incidence and mortality. However, there are sparse data on adherence to the ACS guidelines in cancer survivors. OBJECTIVE: The aim of this study was to describe adherence to the ACS guidelines in female cancer survivors who participated in an exercise intervention trial for 1 year. METHODS: Perimenopausal and early postmenopausal female cancer survivors (n = 154) participated in a randomized controlled trial that examined the efficacy of an aerobic-resistance exercise intervention. In addition to body mass index and alcohol, diet and physical activity data were collected with 4-day diet records and the International Physical Activity Questionnaire. A scoring system was used to determine adherence to the ACS guidelines, with scores ranging from 0 (no adherence) to 8 (highest adherence). RESULTS: Mean total adherence scores for ACS guidelines for all intervention and control condition participants, most of whom had breast or gynecological cancers, were 4.2 (baseline), 4.9 (6 months), and 4.8 (12 months), suggesting moderate adherence. Physical activity levels improved in both groups; however, no significant change was observed for adherence to weight, dietary, or alcohol intake guidelines for either group. CONCLUSION: Findings indicate only partial adherence to the ACS guidelines, even for motivated cancer survivors participating in an exercise intervention study. IMPLICATIONS FOR PRACTICE: Further research is needed regarding strategies and interventions to improve adherence to ACS guidelines.
