Health-related quality of life over chemotherapy course among individuals with early-stage breast cancer: the association of social determinants of health and neighborhood socioeconomic disadvantage.

PURPOSE: This study aimed to examine relationships between health-related quality of life (HRQOL), social determinants of health, and neighborhood socioeconomic disadvantage in individuals with early-stage breast cancer (ESBC) during chemotherapy. METHODS: This is a longitudinal study that recruited Black and White women with ESBC receiving chemotherapy. Participants completed questionnaires recording their sociodemographic information at baseline and the Functional Assessment of Cancer Therapy-General (FACT-G) to report their HRQOL before each chemotherapy cycle. Linear mixed modeling was employed to examine the associations between FACT-G scores, self-reported race, and area deprivation index (ADI) before and at the last chemotherapy cycle, with the duration of chemotherapy treatment as a covariate. RESULTS: A total of 84 Black and 146 White women with ESBC completed the surveys. Linear mixed modeling results suggested that women with ESBC who reported being Black experienced significantly worse physical well-being than those who reported being White throughout chemotherapy, with a 0.22-point lower average (p = 0.02). Both Black and White women with ESBC experienced decreased functional well-being over the chemotherapy, and Black women consistently reported lower scores than White women, with the change in functional well-being over time differing between racial groups (p = 0.03). Participants' ADI national percentiles were not significantly associated with their HRQOL throughout chemotherapy. CONCLUSIONS: These findings underscore possible racial differences in some dimensions of HRQOL during chemotherapy among women with ESBC. Future research should consider further assessing life stressors and past experiences of discrimination and racism that may contribute to these disparities and guide proactive interventions.

Coverage for evidence-based cancer survivorship care services.

PURPOSE: The American Society of Clinical Oncology Cancer Survivorship Committee established a task force to determine which survivorship care services were being denied by public and private payers for coverage and reimbursement. METHODS: A quantitative survey instrument was developed to determine the clinical practice-reported rates of coverage denials for evidence-based cancer survivorship care services. Additionally, qualitative interviews were conducted to understand whether coverage denials were based on payer policies, cost-sharing, or prior authorization. RESULTS: Of 122 respondents from 50 states, respondents reported that coverage denials were common ("always," "most of the time," or "some of the time") for maintenance therapies, screening for new primary cancers or cancer recurrence. Respondents reported that denials in coverage for maintenance therapies were highest for immunotherapy (41.74%) and maintenance chemotherapy (40.17%). Coverage denials for new primary cancer screenings were highest for Hodgkin lymphoma survivors needing a PET/CT scan (49.04%) and breast cancer survivors at a high risk of recurrence who needed an MRI (63.46%), respectively. More than half of survey respondents reported denials for symptom management and supportive care services. Fertility services, dental services when indicated, and mental health services were denied "always" or "most of the time" 23.1%, 22.5%, and 12.8%, respectively. Respondents reported they often had a process in place to automatically appeal denials for evidence-based services. The denial process, however, resulted in greater stress for the patient and provider. CONCLUSION: Our study demonstrates that additional advocacy with payers is needed to ensure that reimbursement policies are consistent with evidence-based survivorship care services.

Economic Hardship and Associated Factors of Women With Early-Stage Breast Cancer Prior to Chemotherapy Initiation.

INTRODUCTION: Economic hardship (EH) can negatively influence cancer outcomes. Little is known about the factors that are associated with higher levels of EH among patients with breast cancer (BC). This paper describes EH in women with early-stage BC prior to or at their first chemotherapy treatment (baseline) and explores whether there are differences by race, area deprivation, stress, symptom distress, and social support. PATIENTS AND METHODS: A descriptive comparative/correlational design was employed using baseline data of a multisite, longitudinal, multimethod study comparing the symptom experience and management prior to prescribed chemotherapy for women with early-stage BC. Participants completed measures for EH, perceived stress, symptom distress, and social support. Race was measured by self-report. Area deprivation indices (ADI) measuring neighborhood economic factors were calculated from publicly available websites. RESULTS: Participants (N = 248; age = 52.9 ± 12.3 years) were 62% White and 38% Black, 54% partnered, and 98% insured. Compared to White patients, Black patients reported higher (worse) EH (1.2 ± 3.0 vs. -0.7 ± 2.4), lived in areas of greater deprivation (80.1 ± 2.1 vs. 50.5 ± 23.5),and were more likely to report inadequate household income (Black: 30.5%; White: 11.1%). Adjusting for race and age, being Black (P< .001), living in an area of greater deprivation (P = .049), higher perceived stress (P = .008), lower perceived appraisal (P = .040), and less tangible support (P < .001) contributed to greater EH. Worse symptom distress trended toward greater EH (P = .07). CONCLUSIONS: This study emphasizes the importance of incorporating baseline holistic assessment to identify patients most likely to experience EH during early-stage BC treatment.

The Effect of Race and Area Deprivation on Symptom Profiles over the Course of Early-Stage Breast Cancer.

Purpose: This study compared common symptoms (fatigue, pain), overall physical functioning and changes over time between Black and White women receiving early-stage breast cancer (ESBC) chemotherapy. Methods: A longitudinal, repeated measures comparative design was employed. Time points of symptom measurement (PROMIS domains) at baseline, mid and end point were adjusted as per patient chemotherapy schedule. Analyses: Linear mixed models were applied. Results: There were 147 patients, 36% Black 64% White (54±12 years) recommended to receive early-stage breast cancer chemotherapy with adequate data for symptom analysis. Pain: Main effect of race was significant (F(1, 390) = 29.43, p<.001) for pain with Black patients experiencing significantly higher pain scores compared to White patients at pretherapy (Mean Difference; MD=3.7, p=.034), midpoint (MD=5.8, p=.002), and endpoint (MD=7.8, p<.001). Fatigue: Fatigue significantly increased (deteriorated) at endpoint (MDT1-T3= 8.7, p<.001) for Black patients. Among White patients, fatigue significantly increased at midpoint (MDT1-T2= 5.7) and at endpoint (MDT1-T3=10.1, p<.001; MDT2-T3=4.3, p= .017). Physical function: Black patients had significantly lower physical function scores compared to White patients at midpoint (MD=4.0, p=.027). Physical function decreased by endpoint in Black (MDT1-T3=7.8, p<.001), and White patients (MDT1-T3=7.7, p<.001). Conclusion: Symptom burden significantly increased over the course of chemotherapy for all patients. Scores for pain and physical function were higher overall for Black patients and deteriorated at a greater rate for Black vs. White women over the course of chemotherapy. This assessment holds implication for proactive assessment and mitigation strategies.

Anaesthesia-related cognitive dysfunction following cardiothoracic surgery in late middle-age and younger adults: A scoping review.

AIM: This review aimed to evaluate factors associated with anaesthesia-related postoperative cognitive dysfunction (POCD) among adults younger than 65 years who underwent cardiothoracic surgeries. STUDY DESIGN: A systematic keyword search, following the scoping review framework, was performed in the PubMed and CINAHL databases. Original English-language studies that included adults younger than 65 years and addressed cognitive function after surgery along with anaesthesia management were included. Retrospective studies, animal research and in vitro and in vivo studies were excluded. RESULTS: Twenty-three articles were included (65.2% interventional studies). All studies lacked theoretical or conceptual frameworks. Ketamine's neuroprotective potential is questionable, and intravenous lidocaine may be considered a possible early agent for preventing POCD, but long-term effectiveness is uncertain. Compared to inhalational anaesthesia, total intravenous anaesthesia (TIVA) may be related to a decreased incidence of POCD. Variation in POCD assessment impacted the lack of homogeneity in obtained data. Moreover, the shorter-term timing of POCD evaluation such as in early days after surgery could be greatly influenced by medication and delirium. CONCLUSION: Although strategies such as TIVA, the use of neuroprotective anaesthetics and comprehensive preoperative assessments are suggested to prevent POCD, this multifactorial phenomenon cannot be explicitly attributed solely to anaesthetics or anaesthesia-related techniques. Use of standardized, reliable and valid tools for POCD assessment is encouraged for cross-study comparison. RELEVANCE TO CLINICAL PRACTICE: Nurses and certified nurse anaesthetists must be aware of risk factors for postoperative delirium and POCD so they can assess patients before and after surgery. Patients and caregivers need to be educated about cognitive changes after surgery and advised to report them to their health care provider if they occur.

Variability of DNA Repair and Oxidative Stress Genes Associated with Worst Pain in Breast Cancer Survivors on Aromatase Inhibitors.

Pain is a problem affecting women with breast cancer (HR+BrCa) receiving aromatase inhibitor (AI) therapy. We investigated the relationship between single-nucleotide polymorphisms (SNPs) in DNA repair and oxidative stress genes and perceived worst pain after 6 months of AI therapy. We explored 39 SNPs in genes involved in DNA repair (ERCC2, ERCC3, ERCC5, and PARP1) and oxidative stress (CAT, GPX1, SEPP1, SOD1, and SOD2) in women with HR+BrCa receiving adjuvant therapy (AI ± chemotherapy; n = 138). Pain was assessed via the Brief Pain Inventory. Hurdle regression was used to evaluate the relationship between each associated allele and (1) the probability of pain and (2) the severity of worst pain. ERCC2rs50872 and ERCC5rs11069498 were associated with the probability of pain and had a significant genetic risk score (GRS) model (p = 0.003). ERCC2rs50872, ERCC5rs11069498, ERCC5rs4771436, ERCC5rs4150360, PARP1rs3219058, and SEPP1rs230819 were associated with the severity of worst pain, with a significant GRS model (conditional mean estimate = 0.45; 95% CI = 0.29, 0.60; p < 0.001). These results suggest DNA repair and oxidative stress pathways may play a role in the probability of pain and the severity of worst pain. As healthcare delivery moves towards the model of precision healthcare, nurses may, in the future, be able to use these results to tailor patient care based on GRS.

A Scoping Review on Work Experiences of Nurses After Being Diagnosed With Cancer.

PROBLEM IDENTIFICATION: To map key concepts underpinning work-related studies about nurses with cancer and identify knowledge gaps. LITERATURE REVIEW: A search was conducted in the PubMed®, CINAHL®, and PsycINFO® databases for articles about nurses with cancer and work-related topics published through March 2023. DATA EVALUATION: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews Checklist was used to report results, and the JBI critical appraisal tools were used to assess the quality of studies. Eleven articles were included. SYNTHESIS: The following four critical concepts were identified: role adjustments at work, cancer impacts on work, organizational support, and translating insights gained from cancer experience into work. Research gaps identified by the scoping review were a lack of theoretical or conceptual frameworks, lack of syntheses of main ideas, and lack of clear data about participants' socioeconomic status across studies. IMPLICATIONS FOR RESEARCH: Minimal research exists to map predictors, outcomes, or intervention targets to guide organizational strategies to support nurses' retention in the nursing workforce. A guiding framework, recruitment of diverse nurses, and focus on the four critical concepts identified in this scoping review are suggested for future research.

Cardiorespiratory fitness is associated with hippocampal resting state connectivity in women newly diagnosed with breast cancer.

Background: Breast cancer and its treatment are associated with aberrant patterns of resting state functional connectivity (rsFC) between the hippocampus and several areas of the brain, which may account for poorer cognitive outcomes in patients. Higher cardiorespiratory fitness (CRF) has been associated with enhanced rsFC and cognitive performance; however, these associations have not been well studied in breast cancer. We examined the relationship between CRF, rsFC of the hippocampus, and cognitive performance among women newly diagnosed with breast cancer. Methods: Thirty-four postmenopausal women newly diagnosed with Stage 0-IIIa breast cancer (Mage = 63.59 ± 5.73) were enrolled in a 6-month randomized controlled trial of aerobic exercise vs. usual care. During baseline assessments, participants completed functional brain imaging, a submaximal CRF test, and cognitive testing. Whole-brain, seed-based analyses were used to examine the relationship between CRF and hippocampal rsFC, with age, years of education, and framewise displacement included as covariates. Cognition was measured with a battery of validated neurocognitive measures, reduced to seven composite factors. Results: Higher CRF was positively associated with greater rsFC of the hippocampus to a cluster within the dorsomedial and dorsolateral frontal cortex (z-max = 4.37, p = 0.003, cluster extent = 1,020 voxels). Connectivity within cluster peaks was not significantly related to cognitive factors (all ps > 0.05). Discussion: CRF was positively associated with hippocampal rsFC to frontal cortex structures, comprising a network of regions commonly suppressed in breast cancer. Future longitudinal research is needed to explore whether baseline rsFC predicts long-term cognitive resilience in breast cancer.

Do Individuals Aged 50 or Older View Cognitive Conditions Differently Than Physical Conditions? Evidence From a Pooled Analysis of Illness Perceptions in Type 2 Diabetes and Mild Cognitive Impairment.

Background and Objectives: Type 2 diabetes (T2DM) and mild cognitive impairment (MCI) are common late-life physical and cognitive health conditions. Illness perceptions, an individual's personal beliefs about the conditions, should be explored in the context of disease characteristics (physical or cognitive). This secondary analysis explored illness perceptions with a priori hypotheses about control (perceived controllability) and coherence (perceived understanding) dimensions among persons with T2DM and MCI, treating each as an exemplar of late-life physical and cognitive health conditions. We also explored whether age, education, and comorbid conditions moderate the relationships between T2DM or MCI condition groups and illness perceptions. Research Design and Methods: This cross-sectional, descriptive study examined baseline data collected from 146 T2DM to 90 MCI participants in 2 independent studies. The 9-item Brief Illness Perception Questionnaire was used to identify the similarities and differences in illness perceptions among persons with T2DM and MCI. We performed hierarchical linear regression controlling for identified covariates. Results: We found that T2DM and MCI participants had significantly different illness perceptions, including perceptions of personal control (b = -0.943, p = .009), treatment control (b = -1.619, p < .001), and coherence (b = -1.265, p = .001), after controlling for covariates. The results suggest that persons with MCI were likely to believe that their condition is less controllable (through their own strategies or medical treatment) and less understandable compared with their T2DM counterparts. Such associations remained statistically significant when the interactions were added to the models. Discussion and Implications: As T2DM and MCI are prevalent late-life conditions, health care professionals should consider individuals' subjective perceptions about their conditions in the context of disease characteristics when counseling secondary prevention strategies for disease management. Further research on illness perceptions in other conditions is needed to ensure the replicability of our findings.

Postdischarge Nausea and Vomiting and Co-occurring Symptoms in Women Following Breast Cancer Surgery.

PURPOSE: The purpose of this study was to investigate the influence of potential co-occurring symptoms, including fatigue, sleep disturbance, anxiety, depressive symptoms, and pain, on the incidence of postdischarge nausea (PDN) measured two days following discharge to home after surgery for breast cancer. DESIGN: This study used a prospective, cross-sectional, observational design. METHODS: The sample was 334 women aged 27 to 88 years of age. Demographic data were collected from the patient and the medical record before surgery. Symptom data were collected 48 hours following surgery using the Patient Reported Outcome Measurement System (PROMIS) and numerical nausea and pain scales. FINDINGS: Eighty-five (25.4%) of study participants reported some nausea two days after discharge. Study participants who experienced PDN frequently described that it occurred after they left the hospital to drive home following their surgery. Unadjusted odds ratios showed the presence of co-occurring symptoms of anxiety, fatigue, sleep disturbance, and pain were all significantly associated with the presence of nausea 48 hours following surgery. Other significant factors associated with (PDN) were history of motion sickness, history of pregnancy-induced nausea, use of opioids, and type of surgery. CONCLUSIONS: Same-day surgery nurses providing postoperative education for women following surgery for breast cancer should explain to patients that nausea may occur after they are discharged, especially those with known motion sickness. In addition, patients should be informed that other symptoms, especially fatigue, sleep disturbance, and anxiety, may co-occur.

Cognitive Function in Adults With Acute Myeloid Leukemia Treated With Chemotherapy: A Systematic Review.

BACKGROUND: Chemotherapy is essential for treating acute myeloid leukemia (AML). Previous studies concluded that survivors of cancer who were treated with chemotherapy experience cognitive impairment. Therefore, it is important to understand cognitive function in survivors of AML. OBJECTIVE: The aim of this study was to explore distributions and correlates of cognitive function, and prediction of cognitive function on other outcomes in adults with AML who were treated with chemotherapy. METHODS: A health science librarian systematically searched PubMed, CINAHL, PsycINFO, and EMBASE databases. Two reviewers independently conducted the title, abstract, and full-text screening. Data were extracted and synthesized based on the aims of the review. RESULTS: A total of 10 articles were included. Findings indicate that up to 62.2% of adults with AML experienced impaired cognitive function after starting chemotherapy. Three studies found cognitive function remained stable over time. Education and cytokines were potential correlates of cognitive function. Worse cognitive function may predict lower physical performance and higher mortality, although the results were inconsistent across studies. CONCLUSION: Impaired cognitive function was observed in adults with AML who were treated with chemotherapy. However, no study used a validated subjective cognitive-function-specific patient-reported questionnaire, and previous studies focusing on cognitive function included relatively young samples. Hence, further research on cognitive function in older adults with AML is needed. IMPLICATIONS FOR PRACTICE: Because of the high prevalence of cognitive impairment identified, it is important to screen cognitive function in adults with AML who are planning to receive chemotherapy to intervene and provide support earlier.

Trajectories of neuropsychological symptom burden in postmenopausal women prescribed anastrozole for early-stage breast cancer.

PURPOSE: Aromatase inhibitors (AIs) prolong survival for postmenopausal women with hormone receptor-positive breast cancer (HR + BC) but also burden patients with symptoms, a major reason for suboptimal AI adherence. This study characterizes inter-relationships among symptom measures; describes neuropsychological symptom burden trajectories; and identifies trajectory group membership predictors for postmenopausal women prescribed anastrozole for HR + BC. METHODS: This study utilized prospectively collected data from a cohort study. Relationships among various self-reported symptom measures were examined followed by a factor analysis to reduce data redundancy before trajectory analysis. Four neuropsychological scales/subscales were rescaled (range 0-100) and averaged into a neuropsychological symptom burden (NSB) score, where higher scores indicated greater symptom burden. Group-based trajectory modeling characterized NSB trajectories. Trajectory group membership predictors were identified using multinomial logistic regression. RESULTS: Women (N = 360) averaged 61 years old, were mostly White, and diagnosed with stage I HR + BC. Several measures were correlated temporally but four neuropsychological measures had strong correlations and dimensional loadings. These four measures, combined for the composite NSB, averaged (mean ± standard deviation) 17.4 ± 12.9, 18.0 ± 12.7, 19.5 ± 12.8, and 19.8 ± 13.0 at pre-anastrozole, 6, 12, and 18 months post-initiation, respectively. However, the analysis revealed five NSB trajectories-low-stable, low-increasing, moderate-stable, high-stable, and high-increasing. Younger age and baseline medication categories (pre-anastrozole), including anti-depressants, analgesics, anti-anxiety, and no calcium/vitamin D, predicted the higher NSB trajectories. CONCLUSION: This study found relationships among neuropsychological symptom measures and distinct trajectories of self-reported NSB with pre-anastrozole predictors. Identifying symptom trajectories and their predictors at pre-anastrozole may inform supportive care strategies via symptom management interventions to optimize adherence for women with HR + BC.

Obesity, Psychological Distress, and Resting State Connectivity of the Hippocampus and Amygdala Among Women With Early-Stage Breast Cancer.

Objective: Overweight and obesity [body mass index (BMI) ≥ 25 kg/m2] are associated with poorer prognosis among women with breast cancer, and weight gain is common during treatment. Symptoms of depression and anxiety are also highly prevalent in women with breast cancer and may be exacerbated by post-diagnosis weight gain. Altered brain function may underlie psychological distress. Thus, this secondary analysis examined the relationship between BMI, psychological health, and resting state functional connectivity (rsFC) among women with breast cancer. Methods: The sample included 34 post-menopausal women newly diagnosed with Stage 0-IIa breast cancer (Mage = 63.59 ± 5.73) who were enrolled in a 6-month randomized controlled trial of aerobic exercise vs. usual care. At baseline prior to randomization, whole-brain analyses were conducted to evaluate the relationship between BMI and seed-to-voxel rsFC of the hippocampus and amygdala. Connectivity values from significant clusters were then extracted and examined as predictors of self-reported depression and anxiety. Results: Mean BMI was in the obese range (M = 31.83 ± 6.62). For both seeds examined, higher BMI was associated with lower rsFC with regions of prefrontal cortex (PFC), including ventrolateral PFC (vlPFC), dorsolateral PFC, and superior frontal gyrus (z range = 2.85-4.26). Hippocampal connectivity with the vlPFC was negatively correlated with self-reported anxiety (ß = 0.47, p < 0.01). Conclusion: Higher BMI was associated with lower hippocampal and amygdala connectivity to regions of PFC implicated in cognitive control and emotion regulation. BMI-related differences in hippocampal and amygdala connectivity following a recent breast cancer diagnosis may relate to future worsening of psychological functioning during treatment and remission. Additional longitudinal research exploring this hypothesis is warranted.

Attention to diet, exercise, and weight in oncology care: Results of an American Society of Clinical Oncology national patient survey.

BACKGROUND: The American Society of Clinical Oncology (ASCO) surveyed cancer patients to assess practice patterns related to weight, diet, and exercise as a part of cancer care. METHODS: An online survey was distributed between March and June 2020 through ASCO channels and patient advocacy organizations. Direct email communication was sent to more than 25,000 contacts, and information about the survey was posted on Cancer.Net. Eligibility criteria included being aged at least 18 years, living in the United States, and having been diagnosed with cancer. Logistic regression was used to determine factors associated with recommendation and referral patterns. RESULTS: In total, 2419 individuals responded to the survey. Most respondents were female (60.1%), 61.1% had an early-stage malignancy, and 48.4% were currently receiving treatment. Breast cancer was the most common cancer (35.7%). The majority of respondents consumed ≤2 servings of fruits and vegetables/d (50.5%) and exercised ≤2 times/wk (50.1%). Exercise was addressed at most or some oncology visits in 56.8% of respondents, diet in 50.1%, and weight in 28.0%. Respondents whose oncology provider provided diet and/or exercise recommendations were more likely to report changes in these behaviors vs. those whose oncology provider did not (exercise: 79.6% vs 69.0%, P < .001; diet 81.1% vs 71.3%, P < .001; weight 81.0% vs 73.3%, P = .003). CONCLUSIONS: In a national survey of oncology patients, slightly more than one-half reported attention to diet and exercise during oncology visits. Provider recommendations for diet, exercise, and weight were associated with positive changes in these behaviors, reinforcing the importance of attention to these topics as a part of oncology care.

Do Perceptions of Cognitive Changes Matter in Self-Management Behaviors Among Persons With Mild Cognitive Impairment?

BACKGROUND AND OBJECTIVES: This secondary analysis examined (a) the association between illness perceptions (perceived understanding and cause of mild cognitive impairment [MCI]) and self-management behaviors for cognitive health, and (b) whether sociodemographic and clinical factors moderate such relationships among persons with MCI. RESEARCH DESIGN AND METHODS: We conducted a cross-sectional study of 85 participants using baseline data from the Return of Amyloid Imaging Scan Results Study. The coherence and causality subscales of the Revised Illness Perceptions Questionnaires were used. Self-management behaviors (dietary changes, physical activity, mental activities, dietary supplements) were assessed using the Risk Evaluation and Education for ALzheimer's disease health behavior measure. Sociodemographic and clinical information was extracted from patients' medical records. We performed hierarchical linear regression and binary logistic regression. RESULTS: We found no main effects for illness perceptions and self-management of cognitive health. Interaction effects were detected, including (a) coherence and age on the total number of self-management behaviors (b = 0.01, p = .04) and on physical activity (p = .04, odds ratio [OR] = 1.02, 95% confidence interval [CI] = 1.00-1.03), (b) causality and age on dietary supplements (p = .03, OR = 1.31, 95% CI = 1.02-1.67), and (c) causality and education on mental activities (p = .02, OR = 0.44, 95% CI = 0.22-0.88). DISCUSSION AND IMPLICATIONS: Findings suggest that age and education moderate the relationship between illness perceptions and self-management behaviors. Health care professionals should consider subjective perceptions about MCI in light of sociodemographic and clinical factors when discussing cognitive health self-management.

Illness Perceptions, Self-efficacy, and Self-reported Medication Adherence in Persons Aged 50 and Older With Type 2 Diabetes.

BACKGROUND: Illness perceptions, patients' beliefs about their health condition, may affect medication adherence as well as self-efficacy for managing the condition in type 2 diabetes (T2DM). OBJECTIVES: The aims of this study were to investigate the associations between illness perceptions, self-efficacy, and self-reported medication adherence among persons (≥50 years of age) with T2DM and explore whether the number of comorbid conditions moderates these associations. METHODS: This secondary analysis of cross-sectional data used baseline data from persons with T2DM. Self-administered questionnaires, including the Brief Illness Perception Questionnaire, Self-efficacy for Managing Chronic Disease, and the 4-item Morisky-Green-Levine Medication Adherence Scale, were used. We performed hierarchical multiple linear regression analyses. RESULTS: Participants (N = 146) were 57.5% female, 67.1% white, and on average 64 years old. Six dimensions of illness perceptions (ie, consequences, personal control, treatment control, identity, concerns, and emotional representations) were associated with self-efficacy for managing T2DM. Five dimensions (ie, timeline, personal control, treatment control, coherence, and emotional representations) were significant predictors of self-reported medication adherence. Whereas the number of comorbid conditions was significantly associated with self-efficacy for managing T2DM in all models (P values < .001), the number of comorbid conditions was not associated with self-reported medication adherence. CONCLUSIONS: This study suggests that illness perceptions and comorbid conditions may play a critical role in either self-efficacy or self-reported medication adherence in persons (≥50 years of age) with T2DM. Future research should incorporate an individual's illness perceptions and comorbid conditions into the development of interventions that may improve both self-efficacy and medication adherence in T2DM.

Physical activity, cardiorespiratory fitness, and cognitive function in postmenopausal women with breast cancer.

Physical activity may improve cognitive function in women with breast cancer. In a cross-sectional study, we explored the relationship between cognitive function and physical activity (actigraph) and cardiorespiratory fitness (sub-maximal graded exercise test) in 73 postmenopausal women with early stage breast cancer prior to the initiation of systemic adjuvant therapy. Cognitive function was assessed with a standardized battery of neurocognitive measures assessing eight domains. Data were analyzed using partial correlations, controlling for age and total hours of actigraph wear-time. Women were, on average, 63.71 (± 5.3) years of age with 15.47 (± 2.48) years of education. For physical activity, greater average number of steps per day were associated with better attention (r = .262, p = .032) and psychomotor speed (r = .301, p = .011); greater average hours of moderate and moderate/vigorous intensity physical activity were associated with better visual memory (r = .241, p = .049; r = .241, p = .049, respectively); and greater average daily energy expenditure was associated with better visual memory (r = .270, p = .027) and psychomotor speed (r = .292, p = .017). For fitness, higher peak maximum VO2 was associated with better concentration (r = .330, p = .006), verbal memory (r = .241, p = .048), and working memory (r = .281, p = .019). These results suggest that higher levels of physical activity and cardiorespiratory fitness are associated with better cognitive function in postmenopausal women with breast cancer. Randomized controlled trials (RCT) to examine whether physical activity improves cognitive function in women with breast cancer are warranted. These RCTs should also determine the mechanisms of the influence of physical activity on cognitive function. CLINICAL TRIALS REGISTRATION NUMBER: NCT02793921; Date: May 20, 2016.

A Conceptual Framework of Self-advocacy in Women With Cancer.

Researchers define self-advocacy as the ability of an individual with cancer to overcome challenges in getting their preferences, needs, and values met. While imperative in all health care settings, self-advocacy is especially important in cancer care. The goal of this article is to present a conceptual framework for self-advocacy in cancer. We review foundational studies in self-advocacy, define the elements of the conceptual framework, discuss underlying assumptions of the framework, and suggest future directions in this research area. This framework provides an empirical and conceptual basis for studies designed to understand and improve self-advocacy among women with cancer.

Protocol for Symptom Experience, Management, Outcomes, and Adherence in Women Receiving Breast Cancer Chemotherapy.

BACKGROUND: The 5-year survival for Black women with breast cancer in the United States is lower than White women for stage-matched disease. Our past and ongoing work and that of others suggest that symptom incidence, cancer-related distress, and ineffective communication contribute to racial disparity in dose reduction and early therapy termination. Although race is perhaps the most studied social determinant of health, it is clear that race alone does not account for all disparities. OBJECTIVES: The aim of the study was to present a study protocol of Black and White women prescribed breast cancer chemotherapy. The aims are to (1) examine and compare chemotherapy received/prescribed over time and in total; (2a) examine and compare symptom incidence, distress, and management and clinical encounter, including patient-centeredness of care and management experience over time and (2b) correlate symptom incidence, distress, and management experience to Aim 1; and (3) explore the effects of social determinants of health, including age, income, education, zip code, and lifetime stress exposure, on Aims 1, 2a, and 2b. METHODS: A longitudinal, repeated-measures (up to 18 time points), comparative, mixed-methods design is employed with 179 White and 179 Black women from 10 sites in Western Pennsylvania and Northeast Ohio over the course of chemotherapy and for 2 years following completion of therapy. RESULTS: The study began in January 2018, with estimated complete data collection by late 2023. DISCUSSION: This study is among the first to explore the mechanistic process for racial disparity in dosage and delay across the breast cancer chemotherapy course. It will be an important contribution to the explanatory model for breast cancer treatment disparity and may advance potential mitigation strategies for racial survival disparity.

Effects of Exercise on Brain and Cognition Across Age Groups and Health States.

Exercise has been shown to benefit brain structure and function, particularly in aging populations. However, the mechanisms by which exercise exerts its effects, especially in humans, are not fully understood. This review argues that one reason for this knowledge gap is that exercise likely operates through multiple levels of mechanisms. Furthermore, the mechanisms of exercise may vary depending on factors such as age and health state. We discuss the state of evidence at each of three levels of analysis (molecular/cellular, brain structure/function, and mental states and higher-order behaviors) and highlight consistencies across these levels, inconsistencies within them, and knowledge gaps. Lastly, based on these, we speculate about which mechanisms of exercise may be universal across age groups and populations versus those that might be distinct to specific age ranges or populations.
