Improving lifestyle behaviors during chemotherapy for breast cancer: The Lifestyle, Exercise, and Nutrition Early After Diagnosis (LEANer) Trial.

BACKGROUND: Little is known about improving physical activity (PA) and diet during and after chemotherapy for breast cancer. This secondary analysis examines changes in PA and diet quality during a yearlong intervention for patients with breast cancer undergoing chemotherapy and evaluates factors associated with these changes. METHODS: Newly diagnosed patients with breast cancer (N = 173) undergoing chemotherapy were randomized to a year-long nutrition and exercise intervention (n = 87) or usual care (UC, n = 86). Mixed models compared 1-year changes in PA and diet quality via the Healthy Eating Index (HEI)-2015 by study arm. Among the intervention group, baseline factors associated with change in PA and diet were assessed with multivariable linear and logistic regression. RESULTS: At 1 year, compared with UC, the intervention arm increased PA more (mean difference = 136.1 minutes/week; 95% CI, 90.2-182.0), participated in more strength training (56% vs. 15%; p < .001), and had suggestive improvements in HEI-2015 (mean difference = 2.5; 95% CI, -0.3 to 5.3; p = .08). In the intervention arm, lower fatigue was associated with improved PA (p = .04) and higher education was associated with improved HEI-2015 (p = .001) at 1 year. Higher HEI-2015 (p = .04) and married/living with someone (p = .05) were associated with higher odds of participating in strength training at 1 year. CONCLUSIONS: This year-long lifestyle intervention for patients with breast cancer undergoing chemotherapy resulted in increases in PA and suggestive improvements in diet quality. Behavior change was associated with baseline fatigue, diet quality, education, and married/living with someone. Addressing these factors in interventions may improve uptake of lifestyle behaviors in trials during and after chemotherapy.

Impact of the Breast Cancer Index for Extended Endocrine Decision-Making: First Results of the Prospective BCI Registry Study.

BACKGROUND: The Breast Cancer Index (BCI) test assay provides an individualized risk of late distant recurrence (5-10 years) and predicts the likelihood of benefitting from extended endocrine therapy (EET) in hormone receptor-positive early-stage breast cancer. This analysis aimed to assess the impact of BCI on EET decision-making in current clinical practice. METHODS: The BCI Registry study evaluates long-term outcomes, decision impact, and medication adherence in patients receiving BCI testing as part of routine clinical care. Physicians and patients completed pre-BCI and post-BCI test questionnaires to assess a range of questions, including physician decision-making and confidence regarding EET; patient preferences and concerns about the cost, side effects, drug safety, and benefit of EET; and patient satisfaction regarding treatment recommendations. Pre-BCI and post-BCI test responses were compared using McNemar's test and Wilcoxon signed rank test. RESULTS: Pre-BCI and post-BCI questionnaires were completed for 843 physicians and 823 patients. The mean age at enrollment was 65 years, and 88.4% of patients were postmenopausal. Of the tumors, 74.7% were T1, 53.4% were grade 2, 76.0% were N0, and 13.8% were HER2-positive. Following BCI testing, physicians changed EET recommendations in 40.1% of patients (P<.0001), and 45.1% of patients changed their preferences for EET (P<.0001). In addition, 38.8% of physicians felt more confident in their recommendation (P<.0001), and 41.4% of patients felt more comfortable with their EET decision (P<.0001). Compared with baseline, significantly more patients were less concerned about the cost (20.9%; P<.0001), drug safety (25.4%; P=.0014), and benefit of EET (29.3%; P=.0002). CONCLUSIONS: This analysis in a large patient cohort of the BCI Registry confirms and extends previous findings on the significant decision-making impact of BCI on EET. Incorporating BCI into clinical practice resulted in changes in physician recommendations, increased physician confidence, improved patient satisfaction, and reduced patient concerns regarding the cost, drug safety, and benefit of EET.

Physical health and function trajectories in adults with cancer: psychosocial predictors of class membership.

PURPOSE: To prospectively examine different trajectories of recovery, across different aspects of physical health and function and to examine trajectory class membership. METHODS: This prospective study enrolled 569 recently diagnosed adult cancer patients (Mage = 58.7) between 2019 and 2022 identified through the Rapid Case Ascertainment resource of The Yale Cancer Center. Patients were diagnosed with breast (63.8%), prostate (25.3%), or colorectal cancer (10.9%) within six-months of baseline assessment. Participants completed comprehensive psychosocial and health survey measures (SF-12) through REDCap at five time points. Growth mixture modeling examined unconditional distinct trajectories for four aspects of physical health and function. We fit logistic regression and multinomial logistic regression models to estimate associations between psychosocial predictors of trajectory class membership for each of the four aspects. RESULTS: We identified distinct trajectories of physical health and function. Over one-third (38.4%) of the sample experienced low and declining scores in their ability to accomplish work/regular daily activities due to physical health. Over half (54.9%) demonstrate moderately stable general health with no improvement over time. A small but significant subset of the sample (3%, 5.7%, 5%) was in the moderate and declining groups with sharp decline in physical function, bodily pain, and general health, after treatment. Different predictors of trajectory class membership were also found. CONCLUSIONS: Our results showed heterogeneity in physical health and function trajectories and different patterns of predictors for each aspect of physical health and function. Findings have the potential to inform screening and intervention efforts to help those who may need additional support.

Post-diagnosis weight trajectories and mortality among women with breast cancer.

Weight gain after breast cancer diagnosis is associated with adverse health outcomes. Yet, few studies have characterized post-diagnosis weight change in the modern treatment era or populations most at risk for weight changes. Among women diagnosed with stages I-III breast cancer in the Smilow Care Network (2013-2019; N = 5441), we abstracted demographic and clinical characteristics from electronic health records and survival data from tumor registries. We assessed if baseline characteristics modified weight trajectories with nonlinear multilevel mixed-effect models. We evaluated body mass index (BMI) at diagnosis and weight change 1-year post-diagnosis in relation to all-cause and breast cancer-specific mortality with Cox proportional hazard models. Women had 34.4 ± 25.5 weight measurements over 3.2 ± 1.8 years of follow-up. Weight gain was associated with ER/PR-, HER2+ tumors, BMI ≤ 18.5 kg/m2, and age ≤ 45 years (+4.90 kg (standard error [SE] = 0.59), +3.24 kg (SE = 0.34), and +1.75 kg (SE = 0.10), respectively). Weight loss was associated with BMI ≥ 35 kg/m2 and age ≥ 70 years (-4.50 kg (SE = 0.08) and -4.34 kg (SE = 0.08), respectively). Large weight loss (≥10%), moderate weight loss (5-10%), and moderate weight gain (5-10%) 1-year after diagnosis were associated with higher all-cause mortality (hazard ratio [HR] = 2.93, 95% confidence interval [CI] = 2.28-3.75, HR = 1.32, 95% CI = 1.02-1.70 and HR = 1.39, 95% CI = 1.04-1.85, respectively). BMI ≥ 35 kg/m2 or BMI ≤ 18.5 kg/m2 at diagnosis were also associated with higher all-cause mortality. Weight change after a breast cancer diagnosis differed by demographic and clinical characteristics highlighting subgroups at-risk for weight change during a 5-year period post-diagnosis. Monitoring and interventions for weight management early in clinical care are important.

Randomized Trial Evaluating a Self-Guided Lifestyle Intervention Delivered via Evidence-Based Materials versus a Waitlist Group on Changes in Body Weight, Diet Quality, Physical Activity, and Quality of Life among Breast Cancer Survivors.

Background: Lifestyle interventions for breast cancer survivors have proved effective at stimulating positive behavior change and promoting healthy weight loss, although integrating these programs into clinical practice is challenging. We evaluated the effect of a 6-month, unsupervised, self-guided, lifestyle intervention using printed materials and online videos vs. waitlist group on body weight for breast cancer survivors. Methods: The Lifestyle, Exercise and Nutrition (LEAN) Self-Guided trial randomized breast cancer survivors with a body mass index ≥25 kg/m2 to a 6-month lifestyle intervention (N = 102) or waitlist group (N = 103). Effects of the intervention on self-reported body weight, physical activity (PA), diet quality (via Health Eating Index-2010 (HEI-2010)), and quality of life were assessed using mixed model repeated measures analysis. Results: At 6 months, the intervention arm had significantly greater weight loss compared with the waitlist group (mean difference = -1.3 kg, 95% confidence interval [CI] = -2.5, -0.13). We observed suggestive improvements in PA (mean difference = 18.7 min/week, 95% CI = -24.2, 61.6), diet quality (mean difference in HEI = 3.2 points, 95% CI = -0.20, 6.5), and fatigue (mean difference in Functional Assessment of Chronic Illness Therapy-Fatigue scale = 1.4 points, 95% CI = -1.1, 3.9). Conclusions: The LEAN Self-Guided intervention led to favorable weight changes over 6 months. Low-resource-intensive programs have the potential to be delivered in diverse healthcare settings and may support breast cancer survivors in achieving a healthy body weight.

Prevalence and Correlates of Cannabis Use among U.S. Veterans during the Second Wave of the COVID-19 Pandemic.

INTRODUCTION: Military veterans are at increased risk of substance use disorders. Limited research is available about veterans' cannabis use (CU) during the coronavirus disease 2019 (COVID-19) pandemic. This study estimated the prevalence of past 30-day CU, investigated individual-level correlates of past 30-day CU, and evaluated the reasons (medical, recreational, or both) of past 30-day CU among U.S. Veterans during the second wave of the COVID-19 pandemic. MATERIALS AND METHODS: We used population-based, cross-sectional data from the 2021 Behavioral Risk Factor Surveillance System Survey Marijuana Use model. The sample included nationally representative military veterans aged 18+ years (n = 11,167). The outcome was past 30-day CU. Individual-level demographic, socioeconomic, behavioral, and clinical correlates were examined. Analyses were weighted to account for the survey's complex design with results generalizable to nearly 2.9 million veterans. We conducted weighted descriptive statistics, prevalence estimates, and multivariable logistic regression analyses. RESULTS: Out of 2.9 million veterans, 11.1% self-reported as non-Hispanic Black, 3.7% Hispanic, and 79.1% non-Hispanic White; 88.5% were men, and 72.8% were aged 50+ years. About 14.6% were current tobacco smokers, 4.7% were current e-cigarette users, 12.5% were binge alcohol drinkers, and 43.4% had three or more comorbid conditions. Overall, 8.5% reported CU in the past 30 days, of which 30.4% used it for medical reasons and 25.8% used it for nonmedical reasons. The prevalence of past 30-day CU decreased with age, education, and income level. Compared to their counterparts, the odds of past 30-day CU were greater among men, those living in urban areas, those with frequent mental distress, infrequent physical distress, and those who had at least one comorbid condition. Non-Hispanic Black veterans had 89% increased odds of past 30-day CU (adjusted odds ratio [AOR] =1.89, 95% confidence interval [CI], 1.19-3.0) compared with non-Hispanic White veterans. Current tobacco smokers had 3.54 (95% CI, 2.40-5.24) and former smokers had 1.78 (95% CI, 1.28-2.47) times higher odds of reporting past 30-day CU than never smokers. Current e-cigarette use (AOR = 3.37, 95% CI, 2.20-5.16) and binge drinking (AOR = 3.18, 95% CI, 2.29-4.41) were also statistically significantly associated with increased odds of past 30-day CU compared to no e-cigarette use and no binge drinking. CONCLUSIONS: CU is prevalent among veterans, and certain subgroups are at higher risk of CU. Thus, identifying high-risk subgroups of veterans and adequately educating them about CU's benefits, risks, and safety is crucial.

Randomized Trial of Exercise and Nutrition on Chemotherapy Completion and Pathologic Complete Response in Women With Breast Cancer: The Lifestyle, Exercise, and Nutrition Early After Diagnosis Study.

PURPOSE: Successful completion of chemotherapy is critical to improve breast cancer outcomes. Relative dose intensity (RDI), defined as the ratio of chemotherapy delivered to prescribed, is a measure of chemotherapy completion and is associated with cancer mortality. The effect of exercise and eating a healthy diet on RDI is unknown. We conducted a randomized trial of an exercise and nutrition intervention on RDI and pathologic complete response (pCR) in women diagnosed with breast cancer initiating chemotherapy. METHODS: One hundred seventy-three women with stage I-III breast cancer were randomly assigned to usual care (UC; n = 86) or a home-based exercise and nutrition intervention with counseling sessions delivered by oncology-certified registered dietitians (n = 87). Chemotherapy dose adjustments and delays and pCR were abstracted from electronic medical records. T-tests and chi-square tests were used to examine the effect of the intervention versus UC on RDI and pCR. RESULTS: Participants randomly assigned to intervention had greater improvements in exercise and diet quality compared with UC (P < .05). RDI was 92.9% ± 12.1% and 93.6% ± 11.1% for intervention and UC, respectively (P = .69); the proportion of patients in the intervention versus UC who achieved ≥85% RDI was 81% and 85%, respectively (P = .44). The proportion of patients who had at least one dose reduction and/or delay was 38% intervention and 36% UC (P = .80). Among 72 women who received neoadjuvant chemotherapy, women randomly assigned to intervention were more likely to have a pCR than those randomly assigned to UC (53% v 28%; P = .037). CONCLUSION: Although a diet and exercise intervention did not affect RDI, the intervention was associated with a higher pCR in patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative and triple-negative breast cancer undergoing neoadjuvant chemotherapy.

The NCCN Guidelines provide screening, evaluation, and treatment recommendations for psychosocial and physical problems resulting from adult-onset cancer and its treatment; recommendations to help promote healthy behaviors and immunizations in survivors; and a framework for care coordination. These NCCN Guidelines Insights summarize recent guideline updates and panel discussions pertaining to sleep disorders, fatigue, and cognitive function in cancer survivors.

Ancillary Treatment Referrals and Visits After Breast Cancer Surgery in a Sociodemographically Diverse Population.

BACKGROUND: Ancillary therapies with rehabilitative, palliative, and survivorship specialists mitigate adverse effects of breast cancer surgery. Existing data suggest that patients from disadvantaged backgrounds may be less likely to receive these services. This study aimed to assess variations in ancillary provider referrals and patient visits at a high-volume urban cancer center. METHODS: Electronic health records of breast cancer surgical patients at the Yale-New Haven Health System between 2010 and 2017 were reviewed. The primary end points were postoperative referral to ancillary service providers and patient use of ancillary services (defined as attending ≥ 1 consultation). Associations between end points and demographic/disease variables were identified in uni- and multivariable logistic regression analyses. RESULTS: The study identified 5496 patients: 2288 patients (41.6%) referred to ancillary services and 1572 patients (28.6%) who attended one or more consultations. Referrals were highest among the patients with Hispanic (57.5%) or black (54.9%) ancestry, no health insurance (57.6%), lowest percentage of high school degrees for the zip code area (50.5%), and poorest median income bracket (50.7%). Associations remained significant in the multivariable analysis (p < 0.05). Minority race remained associated with referrals in analyses of each ancillary service individually. Visits to ancillary specialists were greatest among the patients with private insurance (70.7%), highest percentage of high school degrees (72.8%), highest median household income (72.2%), and Hispanic ethnicity (73.5%). Highest median household income (odds ratio [OR] 1.45; p = 0.02) and Hispanic ethnicity (OR, 1.50; p = 0.05) remained associated in the multivariable analysis. CONCLUSIONS: In a well-resourced health system serving a demographically diverse population, traditional markers of poor health care access were associated with referral for ancillary treatment after breast cancer surgery but not with utilization of ancillary treatment. Health care access remains a critical barrier to adjunctive therapies that target postoperative morbidity and elevate quality of life.

Rekindling Joy in Medicine Through Thoughtful Communication: A Practical Guide.

Joy in medicine, or the loss of it, is a popular topic of conversation, even more so since the pandemic. Burnout in oncology is common and diminishes the satisfaction of practicing medicine. One of the challenges clinicians face is the way in which modern clinical practice takes us away from what we find most meaningful in our work: time with patients. Strategies like being kind, expressing gratitude, and using effective communication skills can establish more connection with our colleagues and our patients, and, in turn, result in a more joyful work environment. Creating space for more moments of feeling deep interconnectedness with patients and colleagues can rekindle feelings of joy in oncology practice. This article reviews the concepts of joy in medicine, the term sacred moments, and outlines practical strategies and communication skills that are effective in enhancing the patient-provider relationship.

Persistence to extended adjuvant endocrine therapy following Breast Cancer Index (BCI) testing in women with early-stage hormone receptor-positive (HR +) breast cancer.

PURPOSE: Extending adjuvant endocrine therapy (ET) beyond the standard 5 years offers added protection against late breast cancer recurrences in women with early-stage hormone receptor-positive (HR +) breast cancer. Little is known about treatment persistence to extended ET (EET) and the role that genomic assays may play. In this study, we evaluated persistence to EET in women who had Breast Cancer Index (BCI) testing. METHODS: Women with stage I-III HR + breast cancer who had BCI testing after at least 3.5 years of adjuvant ET and ≥ 7 years of follow-up after diagnosis were included (n = 240). Data on medication persistence was based on prescriptions in the electronic health record. RESULTS: BCI predicted 146 (61%) patients to have low - BCI (H/I)-low - and 94 (39%) patients to have high likelihood of benefit from EET (BCI (H/I)-high). Continuation of ET after BCI occurred in 76 (81%) (H/I)-high and 39 (27%) (H/I)-low patients. Non-persistence rates were 19% in the (H/I)-high and 38% in the (H/I)-low group. The most common reason for non-persistence was intolerable side effects. Patients on EET underwent more DXA bone density scans than those who stopped ET at 5 years (mean 2.09 versus 1.27; p < 0.001). At a median follow-up of 10 years from diagnosis, there were 6 metastatic recurrences. CONCLUSIONS: In patients who continued ET after BCI testing, the rates of persistence to EET were high, particularly in patients with predicted high likelihood of benefit from EET. Use of EET is associated with increased use of DXA scans.

Partnering With Patients and Caregivers in Cancer Care: Lessons From Experiences With Transgender, Hispanic, and Pediatric Populations.

A cancer diagnosis thrusts patients and caregivers into a foreign world of health care with systems, protocols, and norms that can leave little room for individual needs and circumstances. Quality and efficacious oncology care requires clinicians to partner with patients and caregivers to understand and incorporate their needs, values, and priorities into information sharing, decision making, and care provision. This partnership is necessary for effective patient- and family-centered care and access to individualized and equitable information, treatment, and research participation. Partnering with patients and families also requires oncology clinicians to see that our personal values, preconceived ideas, and established systems exclude certain populations and potentially lead to poorer care for all patients. Furthermore, inequitable access to participation in research and clinical trials can contribute to an unequal burden of cancer morbidity and mortality. Leveraging the expertise of the authorship team with transgender, Hispanic, and pediatric populations, this chapter provides insights and suggestions for oncology care that are applicable across patient populations to mitigate stigma and discrimination and improve the quality of care for all patients.

A review of the impact of energy balance on triple-negative breast cancer.

Cancer cells cannot proliferate without sufficient energy to generate biomass for rapid cell division, as well as to fuel their functions at baseline. For this reason, many recent observational and interventional studies have focused on increasing energy expenditure and/or reducing energy intake during and after cancer treatment. The impact of variance in diet composition and in exercise on cancer outcomes has been detailed extensively elsewhere and is not the primary focus of this review. Instead, in this translational, narrative review we examine studies of how energy balance impacts anticancer immune activation and outcomes in triple-negative breast cancer (TNBC). We discuss preclinical, clinical observational, and the few clinical interventional studies on energy balance in TNBC. We advocate for the implementation of clinical studies to examine how optimizing energy balance-through changes in diet and/or exercise-may optimize the response to immunotherapy in people with TNBC. It is our conviction that by taking a holistic approach that includes energy balance as a key factor to be considered during and after treatment, cancer care may be optimized, and the detrimental effects of cancer treatment and recovery on overall health may be minimized.

Disruption in Cancer Care During Early Survivorship due to the COVID-19 Pandemic and Patient Satisfaction with Telemedicine.

PURPOSE: The extent to which adults with cancer during early survivorship experienced disruptions in care due to COVID-19 pandemic, as well as their experiences with the transition to telemedicine, remains understudied. METHODS: We examined cancer care disruption and satisfaction with telemedicine due to COVID-19 in 361 adults (Mage = 59.42, SD = 11.3) with breast, prostate or colorectal cancer during early survivorship. The Telemedicine Satisfaction and Usefulness Questionnaire (TSUQ) and patient self-report Cancer Care Disruption Index (CCDI) was administered via RedCap survey. RESULTS: The most prevalent areas of patient-reported cancer care disruption included supportive care appointments canceled/postponed (57%), in-person appointments changed to virtual appointments (56%), social work services canceled (32%), palliative care appointments canceled/postponed (24%), elective surgeries related to cancer postponed (23%), and screening tests postponed (19%). Regarding patient satisfaction with telemedicine, 78.0% "agree" or "strongly agree" that they were satisfied with the overall telemedicine system. Most survivors reported satisfaction with their doctor dealing with problems (88.2%), doctors answering patient questions (92.7%), and engaged patients in care (86.1%), However, 49.3% of cancer patients disagreed that virtual visits are as satisfying as in-person visits and 35.6% were dissatisfied with the lack of physical contact during virtual visits. CONCLUSION: The COVID-19 pandemic disrupted cancer survivorship care, with supportive care, social work services, and mode of delivery (in-person vs. virtual) particularly affected. The downstream impact of cancer care disruption in those living with cancer during the pandemic as well as the quality of telehealth modality as part of cancer survivorship care delivery await future investigation.

Diet and physical activity interventions in Black and Latina women with breast cancer: A scoping review.

Background: A growing number of lifestyle interventions are being developed to promote weight loss and adoption of a healthful lifestyles among breast cancer survivors; yet Black and Latina women remain underrepresented. Purpose: We performed a scoping review of the available peer-reviewed literature to describe and compare the content, design, methods, and primary outcomes of current diet and/or physical activity (PA) interventions after a breast cancer diagnosis among Black and Latina women. Methods: We queried PubMed, EMBASE, CINAHL, MEDLINE, and Clinicaltrials.gov up to October 1, 2022, to identify all randomized controlled trials of diet and/or PA after diagnosis of breast cancer with a majority (>50%) of Black or Latina participants. Results: Twenty-two randomized controlled trials were included in this review (five efficacy, twelve pilot, five on-going). Nine trials were among Latinas (two diet, four PA, and three diet/PA), six among Blacks (one PA and five diet/PA) and seven included both populations (five PA and two diet/PA), all of which examined different endpoints. Two of the five efficacy studies achieved their a priori outcome (one diet trial improved short term dietary intake; one PA trial achieved clinically significant improvements in metabolic syndrome score), both in Latinas. Eight pilot trials intervened on both diet and PA and three of them found favorable behavioral changes. Three (two for Latinas and one for Blacks) out of the nine diet and PA trials and three (all for Latinas) efficacy trials incorporated a culturally focused approach (i.e., traditional foods, music, Spanish content, bicultural health coaches, spirituality). Overall, four trials, including one efficacy trial, had one-year follow-up data, with three finding sustained behavior change. Electronic/mobile components were incorporated in five trials and one involved informal care givers. Most of the trials were geographically limited to the Northeast USA (n=8, NY, NC, DC, NJ) and Texas (n=4). Conclusions: Most of the trials we identified were pilot or feasibility studies and of short duration, demonstrating the need for large randomized controlled efficacy lifestyle interventions among Black and Latina breast cancer survivors. Culturally tailored programing was limited but is an important component to incorporate in future trials in these populations.

Antibiotic therapy is associated with adverse drug events among older adults with advanced cancer: A cohort study.

BACKGROUND: Older adults with advanced cancer are exposed to antibiotics but estimates of adverse drug events associated with antibiotic therapy are lacking. AIM: Evaluate the association of antibiotic therapy with adverse drug events in older adults with advanced cancer. DESIGN: Cohort study where the exposure was the ratio of days of therapy of an oral or intravenous antibiotic per patient-day and the outcome was an adverse drug event, defined as cardiotoxicity, hepatotoxicity, nephrotoxicity, Clostridioides difficile infection, or new detection of a multidrug-resistant organism. SETTING/PARTICIPANTS: Patients aged ⩾65 years with solid tumors from a tertiary care center who received palliative chemotherapy (n = 914). RESULTS: Mean age was 75 ± 6.6 years, and 52% were female. Common tumors were lung (31%, n = 284) and gastrointestinal (26%, n = 234). Mean time from first course of palliative chemotherapy to index admission was 128 days. Five-hundred thirty (58%) patients were exposed to antibiotics during the index admission; of these, 27% (n = 143) met standardized criteria for infection. Patients were commonly exposed to cephalosporins (33%, n = 298) and vancomycin (30%, n = 276). Among patients exposed to antibiotics, 35% (n = 183/530) developed an adverse drug event. In multivariable testing, antibiotic therapy was associated with development of an adverse drug event (>0 to <1 vs 0 days of therapy/patient-day: adjusted odds ratio [aOR] = 1.9; 95% confidence interval [CI], 1.2-2.8; ⩾1 vs 0 days of therapy/patient-day: aOR = 2.1, 95% CI, 1.4-3.0). CONCLUSION: Antibiotic therapy was independently associated with adverse drug events in hospitalized older adults with advanced cancer. These findings may inform antibiotic decision-making among palliative care providers.

A qualitative study identifying challenges resulting from complex evidence on lifestyle factors and cancer: perspectives from Black and Latina cancer survivors and healthcare providers.

PURPOSE: Most breast cancer survivors have challenges with adopting healthy lifestyle behaviors. This may be due to contextual challenges that result from the complex nature of the evidence. To address this gap, we explored the experiences of breast cancer survivors of color and oncology healthcare providers. METHODS: Content analysis with inductive and deductive approaches was used for semi-structured interviews with 26 female breast cancer survivors and 10 oncology healthcare providers from Greater New Haven, Connecticut. RESULTS: Survivors identified substantial confusion on the evidence regarding lifestyle behaviors and breast cancer, stemming from inadequate healthcare provider counseling and an overreliance on informal sources of information. Providers identified lack of evidence-based knowledge as a barrier to counseling on these topics. There was a mixed perspective regarding the consistency of evidence, stemming from a combination of gaps in the available evidence and accessing evidence-based knowledge from a wide range of professional resources. Some providers perceived the guidelines as consistent; others felt guidelines were constantly changing, impacting how and on what they counseled. Therefore, many healthcare providers in oncology care relied on generic messaging on lifestyle behaviors after a cancer diagnosis. CONCLUSIONS: Inconsistent information sources, the rapidly changing evidence, and gaps in the current evidence contribute to generic messaging about lifestyle behaviors and may inhibit a survivor's ability to engage in behavior change. Consistent and uniform healthy lifestyle guidelines for cancer outcomes may address both provider and patient level barriers to knowledge.

A qualitative study of sleep in young breast cancer survivors: "No longer able to sleep through the night".

Sleep disturbance is common among women with breast cancer and is associated with greater symptom distress and poorer outcomes. Yet, for the unique subgroup of young women with breast cancer (YWBC), there is limited information on sleep. To address the gap in our understanding of sleep health in YWBC, we explored their perspective on sleep quality, sleep changes over time, contributing factors, and any strategies used to promote sleep. As part of an explanatory sequential mixed method study, we recruited a sub-sample of 35 YWBC (≤ 50 years of age at the time of diagnosis) from the larger quantitative study phase. These participants were within the first 5 years since diagnosis and completed primary and systemic adjuvant therapy. We conducted virtual semi-structured interviews, transcribed them verbatim, and analyzed data with an interpretive description approach. YWBC experience difficulty falling asleep, waking up at night, and not feeling refreshed in the morning. They attributed interrupted sleep to vasomotor symptoms, anxiety/worry, ruminating thoughts, everyday life stressors, and discomfort. The sleep disturbance was most severe during and immediately after treatment but persisted across the 5 years of survivorship. The participants reported trying pharmacologic and non-pharmacologic strategies to improve the quantity and quality of their sleep. Future research would benefit from longitudinal designs to capture temporal changes in sleep and develop interventions to improve sleep health. Clinically, assessment of sleep health is indicated for YWBC related to the prevalence of disturbed sleep. IMPLICATIONS FOR CANCER SURVIVORS: Early access to sleep assessment and management, ideally before cancer treatment, would be beneficial for young breast cancer survivors. In addition, cancer treatment plans should include physical and psychological symptoms, especially those reported by women in this study: vasomotor symptoms, anxiety and worry, discomfort, and pain.
