RESUMO

Adipocyte dysregulation is one mechanism linking overweight and breast cancer recurrence. Exercise and weight loss are associated with a decreased risk of breast cancer recurrence in breast cancer survivors with overweight or obesity, which may be mediated through reduced leptin levels, increased adiponectin levels, and an elevated adiponectin to leptin (A:L) ratio. The four-arm randomized controlled WISER Survivor trial examined the 12-month intervention effects of exercise, weight loss, and the combination of exercise and weight loss on adipokine levels among breast cancer survivors (n = 339) with overweight or obesity. Compared with Control, the Combination of Exercise and Weight Loss decreased leptin levels (-35.9%; 95% CI: -46.8%, -25.0%) and increased A:L ratio (11.6%; 95% CI: 5.6%, 17.6%) but did not change adiponectin levels (4.1%; 95% CI: -3.1%, 11.2%). Compared with Control, Weight Loss Alone decreased leptin levels (-35.6%; 95% CI: -46.6%, -24.5%) and increased A:L ratio (10.6%; 95% CI: 4.7%, 16.5%) but did not change adiponectin levels (0.9%; 95% CI: -6.0%, 7.9%). Compared with Control, Exercise Alone did not change leptin levels, adiponectin levels, or A:L ratio. In analyses that consolidated intervention groups, compared with Control, weight loss of ≥5% decreased leptin levels (p trend < 0.01) and increased A:L ratio (p trend < 0.01) but did not alter adiponectin levels (p trend = 0.53). Weight loss, with or without exercise, was associated with decreased leptin levels in breast cancer survivors with overweight or obesity. Improvements in the adipokine secretion profile (A:L ratio) were primarily driven by a weight loss-induced change in leptin levels.

RESUMO

Background: Metastatic Breast Cancer (MBC) patients often feel their symptom-related needs are unmet, despite visiting their doctors up to once a week. Novel approaches are needed to address symptoms without requiring additional appointments. Technology based symptom management approaches to address symptoms have not been well tested. Methods: Nurse AMIE (Addressing Metastatic Individuals Everyday) is a technology based supportive care platform that provides guideline-concordant symptom management interventions in response to patient reported symptoms. We have previously successfully implemented a tablet version of Nurse AMIE. However, some eligible patients chose not to participate because they were overwhelmed by the technology. To address this barrier, we translated the Nurse AMIE platform to the Amazon Echo Show, which allowed for voice-based interactions. Forty-two MBC patients were randomized 1:1 to receive the Nurse AMIE for Echo Show immediately for six months, or to receive the same intervention for three months, after a three month delay. The primary outcome was change in physical distress over three months, and secondary outcomes included feasibility, acceptability, patient reported outcomes and usability. Conclusions: Results from the Nurse AMIE for Echo Show trial will identify the feasibility, acceptability, and preliminary effects of the Nurse AMIE for Echo Show on patient reported outcomes. Untested novel technologies, particularly voice-based artificial intelligence devices may an effective and scalable vehicle through which we can deliver supportive care interventions. Clinicaltrialsgov identifier: NCT04673019.

RESUMO

BACKGROUND: With an aging population, rising incidence of breast cancer, improved survival rates, and obesity epidemic, there will be a growing population of older adult breast cancer survivors with obesity. This complex population, often with multimorbidity, is at risk for several poor health outcomes, including recurrence, cardiovascular disease, dementia, and diabetes, and a number of deleterious symptoms, including a worsened inflammatory profile, breast cancer- related lymphedema, mobility disability, cognitive impairment, anxiety, and depressive symptoms. A wealth of meta-analytic and randomized controlled trial evidence show that adherence to World Health Organization and 2018 United States Physical Activity guidelines-based levels of moderate-to-vigorous physical activity (MVPA) reduces risk of all-cause mortality, and improves symptoms. However, few survivors engage in recommended levels of MVPA, and symptoms related to their multimorbidity may preclude engaging in sufficient levels of MVPA. Additional research of MVPA in this population is warranted; however, understudied light-intensity physical activity (LIPA) may be a more pragmatic target than MVPA among this complex population facing extensive challenges meeting MVPA recommendations. Large benefits are likely to occur from increasing these survivors' total activity, and LIPA prescriptions may be a more pragmatic approach than MVPA to aid this transition. METHODS: We present a broad, narrative review of the evidence for MVPA and LIPA in this population on an array of health outcomes across the translational science spectrum (clinical, implementation, and public health), and identify a number of directions for future research focused on understanding the potential diverse health effects of LIPA. CONCLUSION: Additional LIPA research is warranted, as LIPA prescriptions may be a pragmatic strategy to effectively promote physical activity to this complex population.

RESUMO

BACKGROUND: Associations between grip strength and mental health disorders have been established; however, associations between grip strength and Generalized Anxiety Disorder (GAD) remain unstudied. Therefore, this study investigates associations between grip strength and prevalent and incident GAD. METHODS: A prospective cohort design was utilized. At baseline, participants aged ≥50 years (N = 3,952) completed a hand grip strength assessment and abbreviated Penn State Worry Questionnaire (PSWQ) and were divided into sex-specific tertiles based on strength. A score of ≥23 on the PSWQ defined caseness of GAD. At two-year follow-up, GAD was assessed with the Composite International Diagnostic Interview-Short Form. RESULTS: Prevalence and incidence of GAD were 18.2% (N = 718) and 0.9% (N = 29), respectively. Adjusting for age, sex, waist circumference, social class, smoking status, and physical activity, a one-standard-deviation (1-SD) increase in strength was associated (OR, 95%CI) with 12.1% (OR = 0.88, 0.80-0.96; p < 0.01) lower odds of prevalent GAD, and middle and high strength tertiles were associated with 27.3% (OR = 0.73, 0.59-0.89; p < 0.01) and 23.1% (OR = 0.77, 0.62-0.95; p < 0.05) lower odds, respectively. A 1-SD increase in strength was non-significantly associated with 24.2% (OR = 0.76, 0.50-1.14) lower odds of incident GAD, and middle and high strength tertiles were non-significantly associated with 31.4% (OR = 0.69, 0.30-1.58) and 66.5% (OR = 0.34, 0.11-1.00) lower odds, respectively (all p > 0.05). There was no significant interaction between strength tertiles and sex. LIMITATIONS: The observational nature of the study limits inferring causality. CONCLUSIONS: Increased hand grip strength may be associated with lower odds of developing GAD in older adults. Larger investigations of prospective associations are needed.

RESUMO

Muscular strength is a modifiable protective factor for mental health across aging populations. Evidence of sex-related differences in its associations with mental health is limited. Therefore, the purpose of this study was to examine sex-related differences in cross-sectional and prospective associations between grip strength and depressive symptoms and status. Participants were community dwelling adults (N = 4505; 56.5% female), aged ≥50 years. As a measure of muscular strength, grip strength (kg) of the dominant hand was assessed using a hand-held dynamometer at baseline. Participants were divided into sex-specific tertiles. The Center for Epidemiological Studies Depression Scale assessed depressive symptoms at baseline and two years later; a score of ≥16 defined caseness of depression. Depressive symptoms were significantly higher among females at baseline (p < 0.001). Prospective models were adjusted for age, sex, waist circumference, social class, smoking, and health status. Among males, the middle and high strength tertiles were non-significantly associated with 32.9% (p = 0.21) and 9.9% (p = 0.74) reduced odds of developing depression, respectively. Among females, the middle and high strength tertiles were non-significantly associated with 28.5% (p = 0.13) and significantly associated with 43.4% (p = 0.01) reduced odds of developing depression, respectively. In the total sample, the middle and high strength tertiles were significantly associated with 31.5% (p = 0.04) and 34.1% (p = 0.02) reduced odds of developing depression, respectively. The interaction between sex and strength was not statistically significant (p = 0.25). The present findings indicated that grip strength was inversely associated with incident depression in older adults, with stronger associations observed among females than males.
