RESUMO

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.

RESUMO

BACKGROUND: Prior research on cognitive and functional outcomes after coronary artery bypass graft (CABG) surgery has largely explored these two domains in isolation. In this study, we assess baseline depression and cognition as risk factors for decline in the Clinical Dementia Rating Sum-of-Boxes (CDR-SB) 1 month post-CABG surgery, which a combined measure of cognition and function. DESIGN: The Neuropsychiatric Outcomes After Heart Surgery study is a prospective observational cohort study. SETTING: A tertiary care, academic center. PARTICIPANTS: Of a total study sample of 148 patients undergoing CABG surgery, 124 (83.8%) completed 1-month follow-up assessment. Mean age was 66.3, 32 (25.8%) female and 112 (90.3%) White. MEASUREMENTS: Cognition, function, and depression were assessed on semi-structured clinical interviews. Cognitive and functional status were defined using CDR-SB; mild or major depression was defined by the Hamilton Depression Rating Scale. Additionally, neuropsychological battery was performed at baseline. RESULTS: CDR-SB decline occurred in 18 (14.5%) subjects. Older age, depression, baseline CDR-SB, and postoperative delirium were associated with 1-month decline on univariate analysis. Older age (OR 1.1 [1.0-1.2]) and depression (OR 6.2 [1.1-35.0]) remained significant on multivariate regression. In separate models, baseline performance on visual Wechsler memory scale (delayed), Hopkins verbal learning test (immediate and delayed), controlled oral word fluency test, and Trails B predicted CDR-SB decline. CONCLUSION: Roughly one in seven patients experienced CDR-SB decline 1 month after CABG surgery. Also, preoperative depression deserves recognition for being a predictor of CDR-SB decline one month post-CABG.

RESUMO

BACKGROUND: Solid organ transplant recipients (SOTRs) are at ∼100-fold increased risk for developing skin cancers compared with the general population, with increased morbidity and mortality. These patients are closely followed by dermatology; however, it is unclear how referral reasons from nondermatologic providers affect care in these patients. OBJECTIVE: This study examines the reason SOTRs are referred to dermatologic care by nondermatologic providers as a potential predictor of nonmelanoma skin cancer (NMSC) outcomes. MATERIALS AND METHODS: A retrospective case-control study was conducted with the records of 353 adult SOTRs referred to a specialized transplant dermatology clinic within an academic tertiary care center between 2007 and mid-2012. RESULTS: Eighty-one patients were diagnosed with 491 total premalignant and malignant skin lesions. A considerable proportion of patients diagnosed with NMSC were referred for benign skin conditions such as rash or acne. CONCLUSION: These results indicate that some SOTRs referred to dermatology for benign skin disorders are incidentally diagnosed with cutaneous malignancies; this is concerning given that referrals for benign skin conditions may delay appropriate care for cutaneous malignancies and preventative care. Better risk stratification, improved interdisciplinary collaboration, and prompt referrals for dermatologic care are needed in the care of SOTRs.

RESUMO

BACKGROUND: The objective of this study was to evaluate the role of a 12-month exercise intervention on endocrine-related quality of life (QOL) and overall QOL among breast cancer survivors with aromatase inhibitor (AI)-induced arthralgia in the Hormones and Physical Exercise (HOPE) Study. METHODS: This was a randomized controlled trial of 121 breast cancer survivors who were currently receiving AIs and experiencing at least mild arthralgia. QOL was assessed using the Functional Assessment of Cancer Therapy (FACT) questionnaires and the 36-Item Short Form Survey (SF-36) at baseline, 6 months, and 12 months. Participants were randomized to either a 1-year gym-based, supervised exercise intervention group (150 minutes of aerobic exercise and 2 strength-training sessions each week) or a usual care group. Effects of the intervention on QOL were assessed using mixed-model, repeated-measures analysis. RESULTS: At 12 months, the exercise group had greater improvement in the overall QOL measures as well as the breast cancer-specific (scores, 2.2 vs 0.7; P = .02), endocrine-specific (scores, 5.6 vs 1.6; P < .001), and fatigue-specific (score, 5.8 vs 0.5; P < .001) subscales compared with the usual care group. The results indicated a stronger effect at 12 months versus 6 months after the intervention. CONCLUSIONS: Combined aerobic and resistance exercise, such as treadmill walking and strength training, improved endocrine-related and overall QOL among breast cancer survivors who were experiencing adverse side effects from AIs. Because adverse side effects associated with AI use are quite common and this is the main reason for treatment discontinuation, this nonpharmacologic intervention could benefit many breast cancer survivors and increase successful adherence to AIs in breast cancer treatment.

RESUMO

PURPOSE: Some studies suggest that telomere shortening may be associated with increased breast cancer risk and mortality. Obesity is also associated with increased breast cancer risk and mortality. Few studies have examined changes in telomere length in overweight or obese breast cancer survivors. The purpose of our study was to examine the effect of a 6-month diet- and exercise-induced weight loss intervention versus usual care on telomere length in breast cancer survivors. METHODS: 151 breast cancer survivors with body mass index (BMI) ≥ 25 kg/m2 were randomly assigned to a 6-month weight loss intervention (n = 93) or to usual care (n = 58). Fasting blood samples, height, weight, physical activity, and diet were measured at baseline and 6-months. Relative telomere length (RTL) was measured by quantitative-polymerase chain reaction (qPCR) done on buffy coat-extracted genomic DNA. Mean baseline to 6-month changes were compared between groups (intention-to-treat) using generalized estimating equations. RESULTS: Complete telomere data were available in 125 participants. Women were 58 ± 8 years, with BMI 33.0 ± 6.2 kg/m2 and were 2.9 ± 2.5 years from diagnosis; 90% were non-Hispanic white, and 76% had stage 0/I breast cancer. After 6 months, women randomized to weight loss had 3% telomere lengthening compared to 5% shortening in the usual care group (p = 0.12). Among women with stage 0/I, the intervention group experienced 7% telomere lengthening compared to 8% shortening in the usual care group (p = 0.01). No intervention effect was observed in women with stage II/III breast cancer. CONCLUSION: Our findings suggest a weight loss intervention in stage 0 and 1 breast cancer survivors may lead to telomere lengthening, compared to a shortening in their usual care counterparts.

RESUMO

Background: We explored the establishment of abnormal blood-brain barrier (BBB) permeability and its relationship to neuropathogenesis during primary human immunodeficiency virus (HIV) infection by evaluating the cerebrospinal fluid (CSF) to serum albumin quotient (QAlb) in patients with primary HIV infection. We also analyzed effects of initiating combination antiretroviral therapy (cART). Methods: The QAlb was measured in longitudinal observational studies of primary HIV infection. We analyzed trajectories of the QAlb before and after cART initiation, using mixed-effects models, and associations between the QAlb and the CSF level of neurofilament light chain (NFL), the ratio of N-acetylaspartate to creatinine levels (a magnetic resonance spectroscopy neuronal integrity biomarker), and neuropsychological performance. Results: The baseline age-adjusted QAlb was elevated in 106 patients with primary HIV infection (median time of measurement, 91 days after infection), compared with that in 64 controls (P = .02). Before cART initiation, the QAlb increased over time in 84 participants with a normal baseline QAlb (P = .006) and decreased in 22 with a high baseline QAlb (P = .011). The QAlb did not change after a median cART duration of 398 days, initiated at a median interval of 225 days after infection (P = .174). The QAlb correlated with the NFL level at baseline (r = 0.497 and P < .001) and longitudinally (r = 0.555 and P < .001) and with the ratio of N-acetylaspartate to creatinine levels in parietal gray matter (r = -0.352 and P < .001 at baseline and r = -0.387 and P = .008 longitudinally) but not with neuropsychological performance. Conclusion: The QAlb rises during primary HIV infection, associates with neuronal injury, and does not significantly improve over a year of treatment. BBB-associated neuropathogenesis in HIV-infected patients may initiate during primary infection.

RESUMO

BACKGROUND: Pulse oximetry does not reliably recognize respiratory depression, particularly in the presence of supplemental oxygen. Capnography frequently detects hypoventilation and apnea among children recovering from anesthesia. Although children are routinely monitored with capnography during anesthesia, reducing the rate of adverse events, it is not routinely used in the postanesthesia care unit (PACU), where patients remain at risk for respiratory depression. AIM: We hypothesized that children monitored with capnography would have more frequent staff interventions and fewer adverse events than children monitored with pulse oximetry alone. METHODS: Otherwise healthy children of age 1-20 years undergoing general anesthesia for elective surgery were eligible for enrollment upon entering the pediatric PACU. Subjects were randomized as to whether PACU staff could view the capnography monitor (intervention group) or not (control group). All children received standard monitoring with pulse oximetry. Vital signs and patient interventions were recorded every 30 s by a portable monitor or a research associate. RESULTS: Data from 201 children were analyzed. The rates of hypopneic hypoventilation [5% (95% CI: 2-8%) per minute vs 1% (95% CI: -1% to 3%) per minute, difference 4% (95% CI: 0.2-8%) per minute; P = 0.04] and apnea [11% (95% CI: 8-14%) per minute vs 1.5% (95% CI: -2% to 5%) per minute, difference 9% (5-14%) per minute; P < 0.001] decreased significantly faster in our intervention group as compared to the control group. The rates of bradypnea decreased faster in our control group [5% (95% CI: 2-8%) per minute vs 1% (95% CI: 0-4%) per minute, difference 4% per minute, 95% CI: 0-9%; P = 0.05]. Rates of respiratory events over time between groups were affected by the presence or absence of interventions. There were no differences in rates of hypoxemia between groups over time. CONCLUSIONS: Children monitored with capnography have different rates of adverse respiratory events over time than children monitored solely with pulse oximetry. The addition of capnography improved the efficacy of staff interventions, however did not impact rates of oxygen desaturation.

RESUMO

BACKGROUND: No psychometrically validated instrument for evaluating the extent to which interventionists correctly implement brief interventions designed to motivate treatment engagement for opioid use disorders has been reported in the literature. The objective of this study was to develop and examine the psychometric properties of the Brief Negotiation Interview (BNI) Adherence Scale for Opioid Use Disorders (BAS-O). METHODS: In the context of a randomized controlled trial evaluating the efficacy of 3 models of emergency department care for opioid use disorders, the authors developed and subsequently examined the psychometric properties of the BAS-O, a 38-item scale that required raters to answer whether or not ("Yes" or "No") each of the critical actions of the BNI was correctly implemented by the research interventionist. BAS-O items pertained to the BNI's 4 steps: (1) Raise the Subject, (2) Provide Feedback, (3) Enhance Motivation, and (4) Negotiate and Advise. A total of 215 audio-recorded BNI and 88 control encounters were rated by 3 trained raters who were independent of the study team and blind to study hypotheses, treatment, and assignment. RESULTS: The results indicated the BAS-O has fair to excellent psychometric properties, in terms of good internal consistency, excellent interrater reliability, discriminant validity, and construct validity, and fair predictive validity. A 13-item, 2-factor solution accounted for nearly 80% of the variance, where factor 1 addressed "Autonomy and Planning" (7 items) and factor 2 addressed "Motivation and Problems" (6 items). However, predictive validity was found for only one of the BAS-O factor items (i.e., Telling patients that treatment will address a range of issues related to their opioid use disorder). CONCLUSIONS: This study suggests that the BAS-O is a psychometrically valid measure of adherence to the specialized BNI for motivating treatment engagement in patients with opioid use disorders, thus providing a brief (13-item), objective method of evaluating BNI skill performance.

RESUMO

BACKGROUND: Children are at risk for respiratory depression while recovering from anesthesia. Currently, monitoring children in the postanesthesia care unit (PACU) with pulse oximetry is recommended. However, pulse oximetry does not reliably recognize hypoventilation or apnea, particularly in the presence of supplemental oxygen. Capnography is a sensitive monitor of ventilation that is not often used in the PACU. AIM: To determine the frequency of hypoventilation and apnea as detected by capnography among children in the PACU. METHODS: In a cross-sectional study, capnography monitoring was applied to healthy children of age 1-17 years in the PACU of a tertiary care hospital. Staff was blinded to the capnography monitor; alarms were disabled. Staff provided routine care and monitoring with pulse oximetry to all patients. Vital signs, patient interventions, and medication administration were recorded by a research assistant every 30 s until all monitoring was discontinued by staff. Outcome measures included frequency of hypoventilation and apnea as measured by capnography and oxygen desaturations as measured by pulse oximetry, as well as staff interventions for these events. RESULTS: Data from 194 children were analyzed. Capnography detected hypoventilation or apnea in 45.5% (95% CI 38.5%, 52.5%) of patients. Oxygen desaturations occurred in 19% (95% CI 13%, 24%) of patients. Interventions occurred in 9% (95% CI 5%, 13%) of patients. Patients who received narcotic medications were more likely to experience hypoventilation (OR 2.3, 95% CI 1.02, 5.3) and apnea (OR 2.7, 95% CI 1.1, 7). Hypoventilation was seen more often among children who received supplemental oxygen (OR 3.1, 95% CI 1.1, 12). CONCLUSIONS: Hypoventilation and apnea are common among children in the PACU; however, few interventions occur to address these events. Routine monitoring with capnography may improve recognition of respiratory depression and enhance patient safety in the PACU.

RESUMO

OBJECTIVE: Data suggest that capnography is a more sensitive measure of ventilation than standard modalities and detects respiratory depression before hypoxemia occurs. We sought to determine if adding capnography to standard monitoring during sedation of children increased the frequency of interventions for hypoventilation, and whether these interventions would decrease the frequency of oxygen desaturations. METHODS: We enrolled 154 children receiving procedural sedation in a pediatric emergency department. All subjects received standard monitoring and capnography, but were randomized to whether staff could view the capnography monitor (intervention) or were blinded to it (controls). Primary outcome were the rate of interventions provided by staff for hypoventilation and the rate of oxygen desaturation less than 95%. RESULTS: Seventy-seven children were randomized to each group. Forty-five percent had at least 1 episode of hypoventilation. The rate of hypoventilation per minute was significantly higher among controls (7.1% vs 1.0%, P = .008). There were significantly fewer interventions in the intervention group than in the control group (odds ratio, 0.25; 95% confidence interval [CI], 0.13-0.50). Interventions were more likely to occur contemporaneously with hypoventilation in the intervention group (2.26; 95% CI, 1.34-3.81). Interventions not in time with hypoventilation were associated with higher odds of oxygen desaturation less than 95% (odds ratio, 5.31; 95% CI, 2.76-10.22). CONCLUSION: Hypoventilation is common during sedation of pediatric emergency department patients. This can be difficult to detect by current monitoring methods other than capnography. Providers with access to capnography provided fewer but more timely interventions for hypoventilation. This led to fewer episodes of hypoventilation and of oxygen desaturation.

RESUMO

BACKGROUND: Central nervous system (CNS) inflammation is a mediator of brain injury in HIV infection. To study the natural course of CNS inflammation in the early phase of infection, we analyzed longitudinal levels of soluble and cellular markers of inflammation in cerebrospinal fluid (CSF) and blood, beginning with primary HIV-1 infection (PHI). METHODS: Antiretroviral-naïve subjects identified as having PHI (less than one year since HIV transmission) participated in phlebotomy and lumbar puncture at baseline and at variable intervals thereafter. Mixed-effects models were used to analyze longitudinal levels of CSF neopterin and percentages of activated cluster of differentiation (CD)4+ and CD8+ T-cells (co-expressing CD38 and human leukocyte antigen-D-related (HLA-DR)) in blood and CSF. RESULTS: A total of 81 subjects were enrolled at an average of 100 days after HIV transmission and had an average follow-up period of 321 days, with the number of visits ranging from one to 13. At baseline, the majority of subjects had CSF neopterin concentrations above the upper limit of normal. The baseline concentration was associated with the longitudinal trajectory of CSF neopterin. In subjects with baseline levels of less than 21 nmol/L, a cutoff value obtained from a mixed-effects model, CSF neopterin increased by 2.9% per 10 weeks (n = 33; P <0.001), whereas it decreased by 6.7% in subjects with baseline levels of more than 21 nmol/L (n = 11; P = 0.001). In a subset with available flow cytometry data (n = 42), the percentages of activated CD4+ and CD8+ T-cells in CSF increased by 0.8 (P <0.001) and 0.73 (P = 0.02) per 10 weeks, respectively. CONCLUSIONS: Neopterin levels and the percentages of activated CD4+ and CD8+ T-cells in CSF progressively increase in most subjects without treatment during early HIV-1 infection, suggesting an accrual of intrathecal inflammation, a major contributor to neuropathology in HIV infection.

RESUMO

BACKGROUND: Potential vitamin D-related influences on inflammatory diseases such as asthma are controversial, including the suggestion that vitamin D insufficiency is associated with increased asthma morbidity. Vitamin D-binding protein transports vitamin D metabolites in the circulation. Single nucleotide polymorphisms in the GC gene encoding vitamin D-binding protein are associated with circulating vitamin D metabolite levels in healthy infants and toddlers. OBJECTIVE: To test the hypothesis that GC single nucleotide polymorphisms encoding the D432E and T436K variants predict subsequent development of asthma in healthy children. METHODS: A retrospective medical record review was performed to determine the development of asthma in 776 children in whom GC genotype, vitamin D-binding protein concentration, and circulating 25-hydroxyvitamin D had been determined at 6 to 36 months of age. Demographic and detailed current clinical data were collected and criteria for asthma were recorded. RESULTS: GC genotype was available for 463 subjects. After an initial analysis of all subject data, the analysis was limited to the predominant Hispanic population (72.1%) to minimize potential confounding effects of ethnicity. Asthma was diagnosed in 87 children (26%). Subjects with the GC genotype encoding the ET/ET (Gc1s/Gc1s) variant had lower odds of developing asthma, representing a protective effect compared with subjects with the DT/DT (Gc1f/Gc1f) variant. CONCLUSION: In the Hispanic population of inner-city New Haven, Connecticut, the ET/ET (Gc1s/Gc1s) genotype of vitamin D-binding protein might confer protection against the development of asthma compared with the wild-type genotype DT/DT (Gc1f/Gc1f).

RESUMO

OBJECTIVE: Capillary integrity continues to challenge critical care physicians worldwide when treating children with sepsis. Vascular growth factors, specifically angiopoietin-1 and angiopoietin-2, play opposing roles in capillary stabilization in patients with sepsis. We aim to determine whether pediatric patients with severe sepsis/shock have persistently high angiopoietin-2/1 ratios when compared with nonseptic PICU patients over a 7-day period. DESIGN: Prospective observational study. Patients were classified within 24 hours of admission into non-systemic inflammatory response syndrome, systemic inflammatory response syndrome/sepsis, or severe sepsis/shock. Plasma levels of angiopoietin-1 and angiopoietin-2 were measured via enzyme-linked immunosorbent assay. The angiopoietin-2/1 ratio was graphically plotted and determined whether patients fell into "constant" or "variable" patterns. SETTING: Tertiary care center PICU. PATIENTS: Critically ill pediatric patients with varying sepsis severity. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Forty-five patients were enrolled (nine non-systemic inflammatory response syndrome, 19 systemic inflammatory response syndrome/sepsis, and 17 severe sepsis/shock). Gender, age, weight, comorbidities, and PICU length of stay were not significantly different between the groups. Admission pediatric risk stratification scores and net fluid ins/outs were significantly elevated in the severe sepsis/shock group when compared (all p < 0.05). Admission angiopoietin-2 levels and angiopoietin-2/1 ratios were significantly different in the severe sepsis/shock group when all groups were compared (both p < 0.05). Additionally, the latter were significantly elevated in the severe sepsis/shock group at multiple time points (all p ≤ 0.05) with the peak occurring on day 2 of illness. In a separate analysis, 32% of systemic inflammatory response syndrome/sepsis and 82% of severe sepsis/shock had variable angiopoietin-2/1 ratio patterns compared with none in the control group (p < 0.001). CONCLUSIONS: Pediatric patients with severe sepsis and septic shock possess significantly elevated angiopoietin-2/1 ratios during their first 3 days of illness, which peak at day 2 of illness. A subset of these patients demonstrated variable angiopoietin-2/1 ratio patterns.

RESUMO

OBJECTIVE: To assess the sensitivity and specificity of neutrophil CD64 as a diagnostic marker for clinical sepsis (based on a hematologic score) and as an additional marker with hematologic parameters for culture-proven sepsis in neonates. STUDY DESIGN: Prospective observational cohort over 18 months in a single-center neonatal intensive care unit. RESULTS: Hematologic and CD64 data were available on 1,156 sepsis evaluations done in 684 infants, of which 411 (36%) instances of positive clinical sepsis were identified. The CD64 index for clinical sepsis had an overall area under the receiver operating characteristic curve of 0.71. An optimum CD64 cut point value of 2.19 for late-onset clinical sepsis was calculated with a sensitivity of 78%, a specificity of 59%, and a negative predictive value of 81%. The birth weight-specific CD64 cut point for early onset clinical sepsis was 3.13, 2.34, and 2.05 for very low, low, and normal birth weight, respectively. Neutrophil CD64, in combination with the absolute neutrophil count or the absolute band count, had the highest sensitivity (91%) and specificity (93%), respectively, to diagnose culture-proven sepsis. CONCLUSION: We conclude that neutrophil CD64 index can be incorporated with specific hematologic criteria as an additional marker for diagnosis of neonatal sepsis.

RESUMO

PURPOSE: Obesity is associated with a higher risk of mortality in women with ovarian cancer. Exercise has improved body composition among cancer survivors, yet no randomized controlled trial has explored the effect of exercise on body composition in women with ovarian cancer. In this analysis, we examined the effect of a six-month aerobic exercise intervention on body composition among ovarian cancer survivors in the Women's Activity and Lifestyle Study in Connecticut (WALC). METHODS: Women with ovarian cancer (N = 144) were randomized in a 1:1 ratio to 6 months of an aerobic exercise intervention or attention-control, and body composition was measured as a secondary outcome at baseline and 6 months via dual-energy X-ray absorptiometry (DEXA). Women with at least one DEXA scan were included in the analysis (N = 103). RESULTS: On average, participants were 57.1 (± 8.7) years old and 1.6 (± 0.9) years since diagnosis. Women randomized to exercise maintained weight during the trial (- 0.11 kg, P = 0.82), while women in attention-control gained weight (+ 1.40 kg, P = 0.03); however, the between-group difference did not reach statistical significance (P = 0.09). We found no statistically significant differences by study arm for changes in body fat percentage, bone mineral density, or lean body mass. CONCLUSIONS: Weight was maintained as a result of a 6-month aerobic exercise intervention among post-treatment ovarian cancer survivors. Future exercise and healthy eating interventions should consider additional measures (e.g., computer tomography scans, D3-creatinine) to more accurately assess changes in body composition. IMPLICATIONS FOR CANCER SURVIVORS: Moderate-intensity aerobic exercise may help ovarian cancer survivors maintain weight.

RESUMO

Importance: Chemotherapy-induced peripheral neuropathy (CIPN), one of the most common and severe adverse effects of chemotherapy, is associated with worse quality of life among survivors of ovarian cancer. Currently, there is no effective treatment for CIPN. Objective: To evaluate the effect of a 6-month aerobic exercise intervention vs attention-control on CIPN among women treated for ovarian cancer in the Women's Activity and Lifestyle Study in Connecticut (WALC) to provide evidence to inform the guidelines and recommendations for prevention or treatment of CIPN. Design, Setting, and Participants: This prespecified secondary analysis evaluated the Women's Activity and Lifestyle Study in Connecticut (WALC), a multicentered, open-label, population-based, phase 3 randomized clinical trial of an aerobic exercise intervention vs attention control for CIPN in patients who were diagnosed with ovarian cancer. Only WALC participants who received chemotherapy were included in this analysis. Participants were randomized 1:1 to either a 6-month aerobic exercise intervention or to attention control. All analyses were conducted between September 2022 and January 2023. Interventions: The exercise intervention consisted of home-based moderate-intensity aerobic exercise facilitated by weekly telephone counseling from an American College of Sports Medicine/American Cancer Society-certified cancer exercise trainer. Attention control involved weekly health education telephone calls from a WALC staff member. Main Outcomes and Measure: Change in CIPN was the primary outcome in this secondary analysis. This outcome was represented by CIPN severity, which was self-measured by participants at baseline and 6 months using the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity scale, with a score range of 0 to 44. A mixed-effects model was used to assess the 6-month change in CIPN between the exercise intervention and attention control arms. Results: Of the 134 participants (all females; mean [SD] age, 57.5 [8.3] years) included in the analysis, 69 were in the exercise intervention arm and 65 were in the attention control arm. The mean (SD) time since diagnosis was 1.7 (1.0) years. The mean (SD) baseline CIPN scores were 8.1 (5.6) in the exercise intervention arm and 8.8 (7.9) in the attention control arm (P = .56). At 6 months, the self-reported CIPN score was reduced by 1.3 (95% CI, -2.3 to -0.2) points in the exercise intervention arm compared with an increase of 0.4 (95% CI, -0.8 to 1.5) points in the attention control arm. The between-group difference was -1.6 (95% CI, -3.1 to -0.2) points. The point estimate was larger among the 127 patients with CIPN symptoms at enrollment (-2.0; 95% CI, -3.6 to -0.5 points). Conclusions and Relevance: Findings of this secondary analysis of the WALC trial indicate that a 6-month aerobic exercise intervention vs attention control significantly improved self-reported CIPN among patients who were treated for ovarian cancer. While replication of the findings in other studies is warranted, incorporating referrals to exercise programs into standard oncology care could reduce CIPN symptoms and increase quality of life in patients with ovarian cancer.

RESUMO

PURPOSE: Factors associated with improving exercise in ovarian cancer survivors remain unknown. We explored characteristics associated with exercise adherence among women treated for ovarian cancer in the Women's Activity and Lifestyle Study in Connecticut (WALC) randomized controlled trial. METHODS: We evaluated adherence among women randomized to the WALC exercise intervention (N = 74). Women had to be exercising ≤ 90 min/week and post-treatment. The intervention included 25 telephone-based exercise counseling sessions over 6 months. Adherence was defined as 150 min/week of moderate/vigorous-intensity exercise. We evaluated factors associated with exercise adherence and duration using multivariate logistic and linear regression. The number of sessions sufficient to achieve 150 min/week was modeled with an unadjusted receiver operating characteristic (ROC) curve. RESULTS: Women were 57.3 ± 8.8 years old and 1.7 ± 1.0 years since diagnosis. The mean exercise time over 6 months was 166.0 ± 66.1 min/week, and 64.9% of women met the 150 min/week goal. Women attended 22.8 ± 3.6 (92%) counseling sessions. No cancer recurrence during the study (OR = 9.15, 95% CI: 1.09-44.02) and greater session attendance (OR = 1.21, 95% CI: 1.02-1.43) were related to meeting the exercise goal. Greater session attendance (P < 0.01) and higher baseline activity level (P = 0.02) were associated with greater average weekly exercise duration. The ROC curve suggested attending 18 counseling sessions was optimal to meet the exercise goal. CONCLUSIONS: Women attending more counseling sessions or with no cancer recurrence during the study were more likely to meet the exercise goal. More research is needed to understand ideal counseling intensity for ovarian cancer survivors. IMPLICATIONS FOR CANCER SURVIVORS: Eighteen counseling sessions are sufficient for ovarian cancer survivors to achieve 150 min/week exercise.

RESUMO

BACKGROUND: In randomized trials in women with breast cancer, exercise has been shown to have beneficial effects on cancer-related circulating biomarkers that may impact survival. Such studies are lacking for ovarian cancer. METHODS: This secondary analysis of a published randomized controlled trial examined the impact of a 6-month exercise intervention versus attention-control on change in prespecified circulating biomarkers (cancer antigen 125 (CA-125), C-reactive protein (CRP), insulin-like growth factor-1(IGF-1), insulin and leptin) in a subset of participants who provided a fasting blood draw (N = 104/144) at enrollment and at 6 months. Change in biomarkers between study arms was compared using a linear mixed effects model analysis. An exploratory analysis of the exercise intervention versus attention-control on all-cause mortality included all (N = 144) participants. All statistical tests were two-sided. RESULTS: Participants included in the biomarker analysis were 57.0 ± 8.8 (mean ± SD) years old and 1.6 ± 0.9 years post-diagnosis. Adherence to the exercise intervention was 176.4 ± 63.5 min/week. Post intervention IGF-1 (group difference in change: -14.2 (-26.1 to -2.3) ng/mL (least squared means (95% CI))) and leptin (-8.9 (-16.5 to -1.4) ng/mL) were significantly reduced in the exercise group (N = 53) compared to those in attention-control (N = 51). No group difference in change was seen for CA-125 (p = 0.54), CRP (p = 0.95), or insulin (p = 0.37). With median follow-up of 70 months [range 6.6-105.4 months], 50/144 (34.7%) (exercise group; 24/74 (32.4%) versus attention-control group; 26/70 (37.1%)) participants died with no between group difference in overall survival (p = 0.99). CONCLUSIONS: Further studies are needed to determine the clinical significance of exercise-induced changes in cancer-related circulating biomarkers in women with ovarian cancer.

RESUMO

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.
