Background: There is emerging research detailing the relationship between balance/gait/falls and cognition. Imaging studies also suggest a link between structural and functional changes in the frontal lobe (a region commonly associated with cognitive function) and mobility. People with Parkinson's disease have important changes in cognitive function that may impact rehabilitation efficacy. Our underlying hypothesis is that cognitive function and frontal lobe connections with the basal ganglia and brainstem posture/locomotor centers are responsible for postural deficits in people with Parkinson's disease and play a role in rehabilitation efficacy. The purpose of this study is to 1) determine if people with Parkinson's disease can improve mobility and/or cognition after partaking in a cognitively challenging mobility exercise program and 2) determine if cognition and brain circuitry deficits predict responsiveness to exercise rehabilitation.Methods/design: This study is a randomized cross-over controlled intervention to take place at a University Balance Disorders Laboratory. The study participants will be people with Parkinson's disease who meet inclusion criteria for the study. The intervention will be 6 weeks of group exercise (case) and 6 weeks of group education (control). The exercise is a cognitively challenging program based on the Agility Boot Camp for people with PD. The education program is a 6-week program to teach people how to better live with a chronic disease. The primary outcome measure is the MiniBESTest and the secondary outcomes are measures of mobility, cognition and neural imaging.Discussion: The results from this study will further our understanding of the relationship between cognition and mobility with a focus on brain circuitry as it relates to rehabilitation potential.Trial Registration: This trial is registered at clinical trials.gov (NCT02231073).

Abstract Background Women with cancer are significantly more likely to fall than women without cancer placing them at higher risk of fall-related fractures, other injuries and disability. Currently, no evidence-based fall prevention strategies exist that specifically target female cancer survivors. The purpose of the GET FIT (Group Exercise Training for Functional Improvement after Treatment) trial is to compare the efficacy of two distinct types of exercise, tai chi versus strength training, to prevent falls in women who have completed treatment for cancer. The specific aims of this study are to: 1) Determine and compare the efficacy of both tai chi training and strength training to reduce falls in older female cancer survivors, 2) Determine the mechanism(s) by which tai chi and strength training each reduces falls and, 3) Determine whether or not the benefits of each intervention last after structured training stops. Methods/Design We will conduct a three-group, single-blind, parallel design, randomized controlled trial in women, aged 50–75 years old, who have completed chemotherapy for cancer comparing 1) tai chi 2) strength training and 3) a placebo control group of seated stretching exercise. Women will participate in supervised study programs twice per week for six months and will be followed for an additional six months after formal training stops. The primary outcome in this study is falls, which will be prospectively tracked by monthly self-report. Secondary outcomes are maximal leg strength measured by isokinetic dynamometry, postural stability measured by computerized dynamic posturography and physical function measured by the Physical Performance Battery, all measured at baseline, 3, 6 and 12 months. The sample for this trial (N=429, assuming 25% attrition) will provide adequate statistical power to detect at least a 47% reduction in the fall rate over 1 year by being in either of the 2 exercise groups versus the control group. Discussion The GET FIT trial will provide important new knowledge about preventing falls using accessible and implementable exercise interventions for women following chemotherapy for cancer.

Abstract The purpose of this review was to: (1) locate all exercise treatment studies of fibromyalgia (FM) patients from 1988 through 2005, (2) present in tabular format the key details of each study and (3) to provide a summary and evaluation of each study for exercise and health outcomes researchers. Exercise intervention studies in FM were retrieved through Cochrane Collaboration Reviews and key word searches of the medical literature, conference proceedings and bibliographies. Studies were reviewed for inclusion using a standardized process. A table summarizing subject characteristics, exercise mode, timing, duration, frequency, intensity, attrition and outcome variables was developed. Results, conclusions and comments were made for each study. Forty-six exercise treatment studies were found with a total of 3035 subjects. The strongest evidence was in support of aerobic exercise a treatment prescription for fitness and symptom and improvement. In general, the greatest effect and lowest attrition occurred in exercise programs that were of lower intensity than those of higher intensity. Exercise is a crucial part of treatment for people with FM. Increased health and fitness, along with symptom reduction, can be expected with exercise that is of appropriate intensity, self-modified, and symptom-limited. Exercise and health outcomes researchers are encouraged to use the extant literature to develop effective health enhancing programs for people with FM and to target research to as yet understudied FM subpopulations, such as children, men, older adults, ethnic minorities and those with common comorbidities of osteoarthritis and obesity.

Objective: This study aimed to characterize mobility patterns using wearable inertial sensors and serial assessment across autologous hematopoietic cell transplant (autoHCT) and investigate the relation between mobility and perceived function in patients with hematologic cancer., Design: Prospective longitudinal study., Setting: Hospital adult transplant clinic followed by discharge., Participants: 78 patients with hematological cancer receiving autoHCT., Main Outcome Measures: Mobility was measured across 3 clinical phases (pretransplant, pre-engraftment, and post-engraftment) in using inertial sensors worn during prescribed performance tests in the hospital. Perceived function was assessed using validated provider-reported (Eastern Cooperative Oncology Group [ECOG] Performance Status Scale) and patient-reported [European Organization for Research and Treatment of Cancer Quality of Life Questionnaire [EORTC QLQ-C30]) measures. Trajectories of 5 selected mobility characteristics (turn duration, gait speed, stride time variability, double support time, and heel strike angle) across the clinical phases were also evaluated using piecewise linear mixed-effects models., Results: Using Principal Components Analysis, 4 mobility patterns were identified pretransplant: Gait Limitation, Sagittal Sway, Coronal Sway, and Balance Control. Gait Limitation measured pretransplant was significantly inversely associated with perceived function reported by the provider- (β = -0.11; 95% CI: -0.19, -0.02) and patient- (β = -4.85; 95% CI: -7.72, -1.99) post-engraftment in age-adjusted linear regression models. Mobility characteristics demonstrated immediate declines early pre-engraftment with stabilization by late pre-engraftment., Conclusion: Patients with hematological cancer experiencing gait limitations pretransplant are likely to have worse perceived function post-engraftment. Mobility declines in early phases post-transplant and may not fully recover, indicating an opportunity for timely rehabilitation referrals. Wearable inertial sensors can be used to identify early mobility problems and patients who may be at risk for future functional decline who may be candidates for early physical rehabilitation., (Copyright © 2024 American Congress of Rehabilitation Medicine.

Background: Active surveillance (AS) is standard care for most men with low-risk prostate cancer (PC); yet, many men on AS eventually undergo curative therapy. Interventions to lower the risk of cancer progression and fear of recurrence among men on AS for PC are needed., Objective: To determine the effect of aerobic exercise on cardiorespiratory fitness, body size, and quality of life (QOL) among men on AS for PC., Design, Setting, and Participants: We conducted a 1:1 randomized controlled trial among 51 men with low-risk PC who elected AS. Participants were enrolled at the University of California, San Francisco., Intervention: The 16-wk intervention included a home-based walking program with a nonlinear exercise prescription tailored to baseline fitness level, heart rate monitor, and weekly phone call with an exercise physiologist. Controls received printed materials., Outcome Measurements and Statistical Analysis: Cardiorespiratory fitness was measured using VO 2 peak; secondary outcomes included change in body size, anxiety, and QOL. Analyses were based on intention to treat., Results and Limitations: Between 2016 and 2021, we randomized 51 men to intervention (n = 26) or control (n = 25). Follow-up was 88% (45/51), 85% (22/26) in the intervention and 92% (23/25) in the control group. At 16 wk, the intervention group had a higher mean VO 2 peak than the control group (31.9 ± 4.7 vs 27.2 ± 4.8 ml/kg/min; group × time effect p value: <0.001). Additionally, the intervention group reported less fear of PC recurrence and urinary obstruction/irritation, while controls reported more of these two QOL measures, from 0 to 16 wk (p = 0.04 and 0.03, respectively). Two participants discontinued the intervention, including one due to knee pain related to the study., Conclusions: A home-based walking program improved VO 2 peak and reduced urinary obstruction/irritation and fear of recurrence among men on AS for PC., Patient Summary: Moderate to vigorous aerobic exercise improves fitness and quality of life among men on active surveillance for prostate cancer., (Copyright © 2023 The Authors.

Guided by the Dyadic Theory of Illness Management, we explored spousal health management behaviors and their congruence within seventeen older African American married couples participating in a dyadic exercise intervention. Both prior to and after the intervention, spouses reported how they took care of their partner's health as well as what their partner did for them. Data were analyzed using theoretical thematic analysis, and five health management behaviors domains were identified (diet, exercise, self-care, medical compliance, relationship maintenance). Both partners were most likely to encourage healthier diets and exercise. Wives tended to report more behaviors compared to husbands. Couples had little congruence in their appraisals of each other's health management behaviors, and patterns were stable over time. Findings suggest incongruence in couples' health management behaviors represented complementary, collaborative efforts to support each other and that husbands may underestimate how much care they both provide to and receive from their wives., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: The American College of Sports Medicine provided guidelines for exercise prescriptions in cancer survivors for specific cancer- and treatment-related health outcomes. However, there was insufficient evidence to generate exercise prescriptions for 10 health outcomes of cancer treatment. We sought to update the state of evidence., Methods: We conducted a systematic review of these 10 understudied health outcomes (bone health, sleep, cardiovascular function, chemotherapy-induced peripheral neuropathy (CIPN), cognitive function, falls and balance, nausea, pain, sexual function, and treatment tolerance) and provided an update of evidence., Results: While the evidence base for each outcome has increased, there remains insufficient evidence to generate exercise prescriptions. Common limitations observed across outcomes included: variability in type and quality of outcome measurement tools, variability in definitions of the health outcomes, a lack of phase III trials, and a majority of trials investigating breast or prostate cancer survivors only., Conclusion: We identified progress in the field of exercise oncology for several understudied cancer- and treatment-related health outcomes. However, we were not able to generate exercise prescriptions due to continued insufficient evidence base. More work is needed to prescribe exercise as medicine for these understudied health outcomes, and our review highlights several strategies to aid in research acceleration within these areas of exercise oncology., (© 2023 The Authors.

Older adults' readiness to participate in fall prevention behaviors is largely unknown. We evaluated the feasibility of recruitment for a fall prevention intervention and participants' readiness to participate in fall prevention activities. Patients ≥ 65 years at high fall risk were recruited. Feasibility of recruitment was assessed by reaching the goal sample size (200), and recruitment rate (50%). Surveys assessed participants' readiness to participate in fall prevention activities (confidence to manage fall risks [0-10 scale; 10 most confident] and adherence to fall prevention recommendations). We recruited 200 patients (46.3% of eligible patients), and 185 completed surveys. Participants reported high confidence (range 7.48 to 8.23) in addressing their risks. Their adherence to clinician recommendations was mixed (36.4% to 90.5%). We nearly met our recruitment goals, and found that older adults are confident to address their fall risks, but do not consistently engage in fall prevention recommendations., Competing Interests: Declaration of Competing Interest The authors of the paper “Motivational Interviewing for Fall Prevention (MI-FP) Pilot Study: Feasibility of Recruitment and Participants’ Baseline Engagement in Fall Prevention” do not have any financial or personal relationship that could cause a conflict of interest regarding this article.

Background: Mild cognitive impairment (MCI) negatively impacts cognition and dual-task abilities. A physical-cognitive integrated treatment approach could mitigate this risk for dementia., Objective: To compare the effectiveness of cognitively enhanced tai ji quan versus standard tai ji quan or stretching exercise in improving global cognition and reducing dual-task walking costs in older adults with MCI or self-reported memory concerns., Design: 3-group, randomized (1:1:1), superiority trial. (ClinicalTrials.gov: NCT04070703)., Setting: Community residential homes., Participants: 318 older adults with self-reported memory decline or concern and a Clinical Dementia Rating (CDR) global score of 0.5 or lower at baseline., Intervention: Cognitively enhanced tai ji quan ( n = 105), standard tai ji quan ( n = 107), or stretching ( n = 106). All groups exercised at home via real-time videoconferencing, 1 hour semiweekly for 24 weeks., Measurements: The co-primary endpoints were change in Montreal Cognitive Assessment (MoCA; range, 0 to 30) and dual-task walking costs (difference between single- and dual-task gait speed, expressed in percentage) from baseline to 24 weeks. Secondary outcomes included CDR-Sum of Boxes (CDR-SB), Trail Making Test B, Digit Span Backward (DSB), and physical performance tests. Outcomes were assessed at 16, 24 (primary endpoint), and 48 weeks (6 months after intervention)., Results: A total of 304 participants (96%) completed the 24-week assessment. Cognitively enhanced tai ji quan outperformed standard tai ji quan and stretching with a greater improvement in MoCA score (mean difference, 1.5 points [98.75% CI, 0.7 to 2.2 points] and 2.8 points [CI, 2.1 to 3.6 points], respectively) and in dual-task walking (mean difference, 9.9% [CI, 2.8% to 16.6%] and 22% [CI, 13% to 31%], respectively). The intervention effects persisted at 48-week follow-up., Limitation: There was no nonexercise control group; participants had subjective or mild cognitive impairment., Conclusion: Among community-dwelling older adults with MCI, cognitively enriched tai ji quan therapy was superior to standard tai ji quan and stretching exercise in improving global cognition and reducing dual-task gait interference, with outcomes sustained at 48 weeks., Primary Funding Source: National Institute on Aging., Competing Interests: Disclosures: Disclosures can be viewed at www.acponline.org/authors/icmje/ConflictOfInterestForms.do?msNum=M23-1603.

Purpose: This scoping review describes the assessment methodologies for physical activity (PA) and physical fitness assessments used in studies focusing on adolescents and young adults (AYAs) diagnosed with cancer., Methods: A search of the literature was conducted in PubMed, CINAHL, Web of Science, and Cochrane Library following the PRISMA-ScR statement. A total of 34 studies were included in this review., Results: PA was primarily assessed via self-reported questionnaires (30/34) either completed in-person (n = 17) or online (n = 13) at different time points and different stages along the cancer trajectory (i.e., from diagnosis onward). A total of 9 studies conducted a physical fitness assessment., Conclusions: PA and physical fitness measurements are key when trying to describe outcomes, assess for associations, track changes, measure intervention adherence, and test intervention efficacy and effectiveness. Considerable heterogeneity across studies was reported limiting the generation of formal recommendations or guidance for researchers, healthcare providers, and policy makers., (© 2023.

Background: Physical frailty is strongly related to adverse outcomes in heart failure (HF), and women are more likely to be physically frail than men; however, it is unknown if this sex difference affects outcomes., Objectives: To determine if there are sex differences in the associations between physical frailty and health-related quality of life (HRQOL) and clinical outcomes in HF., Methods: We conducted a prospective study of adults with HF. Physical frailty was assessed using the Frailty Phenotype Criteria. HRQOL was assessed using the Minnesota Living with HF Questionnaire. One-year clinical events (all-cause death or cardiovascular hospitalization or emergency department visit) were ascertained. We used generalized linear modeling to quantify associations between physical frailty and HRQOL, and Cox proportional hazards modeling to quantify associations between physical frailty and clinical events, adjusting for Seattle HF Model scores., Results: The sample (n = 115) was 63.5 ± 15.7 years old and 49% women. Physical frailty was associated with significantly worse total HRQOL among women (p = 0.005) but not men (p = 0.141). Physical frailty was associated with worse physical HRQOL among both women (p < 0.001) and men (p = 0.043). There was a 46% higher clinical event risk for every one-point increase in physical frailty score among men (p = 0.047) but not women (p = 0.361)., Conclusions: Physical frailty is associated with worse overall HRQOL among women and higher clinical event risk among men, indicating a need to better understand contributors to sex-specific health differences associated with physical frailty in HF., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023 Elsevier Inc.

Background: Describing changes in health and behavior that precede and follow a sentinel health event, such as a cancer diagnosis, is challenging because of the lack of longitudinal, objective measurements that are collected frequently enough to capture varying trajectories of change leading up to and following the event. A continuous passive assessment system that continuously monitors older adults' physical activity, weight, medication-taking behavior, pain, health events, and mood could enable the identification of more specific health and behavior patterns leading up to a cancer diagnosis and whether and how patterns change thereafter., Objective: In this study, we conducted a proof-of-concept retrospective analysis, in which we identified new cancer diagnoses in older adults and compared trajectories of change in health and behaviors before and after cancer diagnosis., Methods: Participants were 10 older adults (mean age 71.8, SD 4.9 years; 3/10, 30% female) with various self-reported cancer types from a larger prospective cohort study of older adults. A technology-agnostic assessment platform using multiple devices provided continuous data on daily physical activity via wearable sensors (actigraphy); weight via a Wi-Fi-enabled digital scale; daily medication-taking behavior using electronic Bluetooth-enabled pillboxes; and weekly pain, health events, and mood with online, self-report surveys., Results: Longitudinal linear mixed-effects models revealed significant differences in the pre- and postcancer trajectories of step counts (P<.001), step count variability (P=.004), weight (P<.001), pain severity (P<.001), hospitalization or emergency room visits (P=.03), days away from home overnight (P=.01), and the number of pillbox door openings (P<.001). Over the year preceding a cancer diagnosis, there were gradual reductions in step counts and weight and gradual increases in pain severity, step count variability, hospitalization or emergency room visits, and days away from home overnight compared with 1 year after the cancer diagnosis. Across the year after the cancer diagnosis, there was a gradual increase in the number of pillbox door openings compared with 1 year before the cancer diagnosis. There was no significant trajectory change from the pre- to post-cancer diagnosis period in terms of low mood (P=.60) and loneliness (P=.22)., Conclusions: A home-based, technology-agnostic, and multidomain assessment platform could provide a unique approach to monitoring different types of behavior and health markers in parallel before and after a life-changing health event. Continuous passive monitoring that is ecologically valid, less prone to bias, and limits participant burden could greatly enhance research that aims to improve early detection efforts, clinical care, and outcomes for people with cancer., (©Chao-Yi Wu, Deanne Tibbitts, Zachary Beattie, Hiroko Dodge, Jackilen Shannon, Jeffrey Kaye, Kerri Winters-Stone.

Objective: To facilitate replication and future intervention design of web-based multibehavior lifestyle interventions, we describe the rationale, development, and content of the A i M , P lan, and act on LIF est Y les (AMPLIFY) Survivor Health intervention which provides healthy eating and exercise behavior change support for older cancer survivors. The intervention promotes weight loss, improvements in diet quality, and meeting exercise recommendations., Methods: The Template for Intervention Description and Replication (TIDieR) checklist was used to provide a comprehensive description of the AMPLIFY intervention, consistent with CONSORT recommendations., Results: A social cognitive theory web-based intervention founded on the core components of efficacious print and in-person interventions was conceptualized and developed through an iterative collaboration involving cancer survivors, web design experts, and a multidisciplinary investigative team. The intervention includes the AMPLIFY website, text and/or email messaging, and a private Facebook group. The website consists of: (1) Sessions (weekly interactive e-learning tutorials); (2) My Progress (logging current behavior, receiving feedback, setting goals); (3) Tools (additional information and resources); (4) Support (social support resources, frequently asked questions); and (5) Home page. Algorithms were used to generate fresh content daily and weekly, tailor information, and personalize goal recommendations. An a priori rubric was used to facilitate intervention delivery as healthy eating only (24 weeks), exercise only (24 weeks), or both behaviors concurrently over 48 weeks., Conclusions: Our TIDieR-guided AMPLIFY description provides pragmatic information helpful for researchers designing multibehavior web-based interventions and enhances potential opportunities to improve such interventions., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

Introduction: Older men with prostate cancer are commonly affected by reductions in lean mass and physical function following androgen deprivation therapy (ADT). Resistance-based exercise programs are critical to counteract the musculoskeletal toxicities derived from prostate cancer treatment and aging. However, there is significant variability in the effects of exercise interventions. Examining demographic and clinical moderators of exercise effects in this patient group can assist in identifying which subgroups of patients benefit most. Therefore, we examined the effects and moderators of resistance-based exercise programs on sarcopenia-related outcomes that included lean mass, skeletal muscle index, physical function, and muscle strength in older men with prostate cancer., Materials and Methods: Data were retrieved from the Predicting OptimaL cAncer RehabIlitation and Supportive care (POLARIS) consortium. For the present study, we included data from trials that examined the effects of supervised resistance-based exercise interventions on lean mass outcomes, muscle strength, and physical function in patients with prostate cancer previously or currently treated with ADT. Linear mixed models were undertaken to analyse the effects of resistance-based exercise programs considering the clustering of patients within studies. Effects were evaluated by regressing the study group on the post-intervention value of the outcome adjusted for the baseline value, while potential moderators were examined by adding the moderator and its interaction term into the regression model., Results: A total of 560 patients with prostate cancer (age: 69.5 ± 7.8 yrs.; body mass index: 28.6 ± 4.0 kg.m -2 ) previously or currently treated with ADT were included. Resistance-based exercise programs resulted in significant effects on whole-body and appendicular lean mass and the skeletal muscle index (P < 0.05), with improvements observed across different characteristics. Improvements were also observed in 400-m walk and 6-m backwards tandem walk (P < 0.05), with patients presenting with lower baseline levels deriving greater exercise effects on 400-m walk (-19.4 s, 95% confidence interval [CI]: -36.6 to -2.3) and 6-m backwards tandem walk tests (-3.0 s, 95% CI: -5.7 to -0.3). For relative muscle strength, significant exercise effects were observed, with greater effects in younger patients (0.35 kg.kg -1 , 95% CI: 0.22 to 0.48)., Discussion: Resistance-based exercise programs effectively improve well-known markers of sarcopenia in men with prostate cancer, with specific subgroups of patients, such as those younger and presenting with lower baseline levels of physical function, deriving greater effects on muscle strength and physical function, respectively., Competing Interests: Declaration of Competing Interest None to declare., (Copyright © 2023 The Authors.

Purpose: To examine the effects and moderators of exercise effects on cardiometabolic outcomes in men with prostate cancer previously or currently undergoing androgen deprivation therapy (ADT)., Results: Seven trials including 560 patients were examined. Exercise resulted in significant effects on whole-body and regional fat mass (P ≤ 0.001). For whole-body fat mass, significant exercise effects were observed in patients who were unmarried (-1.4 kg, P < 0.05) and who presented with higher fat mass levels (-1.0 kg, P < 0.05). For diastolic blood pressure and low-density lipoprotein (LDL), younger (-4.7 mmHg, P < 0.05) and older patients (-0.2 mmol.l -1 , P < 0.10) achieved greater effects, respectively. Regarding high-density lipoprotein (HDL), patients undertaking ADT + prostatectomy + radiotherapy derived significant exercise effects (0.3 mmol.l -1 , P < 0.05)., Conclusions: Exercise effectively reduces fat mass across subgroups of men undergoing or following ADT with different characteristics. For diastolic blood pressure, HDL and LDL, groups based on age and treatment history could be specifically targeted with exercise medicine., Competing Interests: Conflict of Interests Statement None to declare., (Copyright © 2023 The Authors.

Clinicians who care for men with prostate cancer should co-prescribe exercise with adjuvant therapy to mitigate treatment-related symptoms and side effects and improve quality of life. While moderate levels of resistance training are highly recommended, clinicians can reassure their patients with prostate cancer that exercise of any type, frequency, or duration at tolerable levels of intensity can have some benefit for their overall health and wellbeing., (Copyright © 2023 European Association of Urology.

Objective: Adults with heart failure (HF) may be at high risk for falling due to age, comorbidities and frailty; however, few studies have examined falls in HF. The purpose of this study was to quantify the frequency and predictors of falls over 1 year among adults with HF., Methods: We conducted a prospective study of adults with New York Heart Association (NYHA) functional class I-IV HF. After baseline assessment of physical frailty and clinical characteristics, participants self-reported falls every 3 months during 1 year. Comparative statistics were used to identify baseline differences between those who fell vs those who did not. A stepwise negative binomial regression model was used to identify predictors of fall rate over 1 year., Results: The sample (n = 111) was 63.4 ± 15.7 years old, 48% were women, 28% had HF with preserved ejection fraction, and 41% were frail. Over 1 year, 43 (39%) of participants reported at least 1 fall and 28 (25%) of participants reported 2+ falls. Among those who fell, 29 (67%) reported injurious falls. Those who fell had significantly higher body mass indexes and were more likely to have NYHA class III/IV, type 2 diabetes and HF with preserved ejection fraction and to meet slowness and physical exhaustion criteria than those who did not fall. The fall rate was elevated among those with type 2 diabetes and those meeting the slowness and physical exhaustion criteria for physical frailty., Conclusions: Nearly 40% of adults with HF experienced a fall within 1 year. Screening for comorbidities, slowness and exhaustion may help to identify those at risk for a fall., Competing Interests: Declaration of Conflicting Interests None., (Copyright © 2022 Elsevier Inc.

Aims: Physical frailty is highly prevalent and predictive of worse outcomes in heart failure (HF). Candidate biomarker analysis may help in understanding the mechanisms underlying physical frailty in HF. We aimed to identify candidate biomarkers associated with physical frailty in HF using a multimarker strategy of distinct pathophysiological processes., Methods and Results: We collected data and plasma samples from 113 adults with New York Heart Association Functional Class I-IV HF. Physical frailty was measured with the Frailty Phenotype Criteria. Plasma biomarkers included: N-terminal pro-B-type natriuretic peptide, norepinephrine, dihydroxyphenylglycol, soluble tumour necrosis factor alpha receptor-1, adiponectin, insulin, glucose, insulin-like growth factor-1 (IGF-1), and myostatin. Comparative statistics and multivariate linear regression were used to test group differences and associations. The average age was 63.5 ± 15.7 years, half were women (48%), and most had a non-ischaemic aetiology of HF (73%). Physical frailty was identified in 42% and associated with female sex, higher body mass index and percent body fat, more comorbidities, and HF with preserved ejection fraction. Adjusting for Seattle HF Model projected survival score, comorbidities, body composition, and sex, physical frailty was associated with significantly lower plasma adiponectin [β ± standard error (SE) -0.28 ± 0.14, P = 0.047], IGF-1 (β ± SE -0.21 ± 0.10, P = 0.032), and myostatin (β ± SE -0.22 ± 0.09, P = 0.011). In sex-stratified analyses, IGF-1 and myostatin were significantly associated with physical frailty in men but not women., Conclusion: We identified biomarkers involved in adipose tissue and skeletal muscle development, maintenance, and function that were associated with physical frailty in HF., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2022.

Background: Nutrition and physical activity are associated with prostate cancer recurrence and mortality. Few randomized controlled trials (RCT) have examined the effects of long-term exercise and diet changes on prostate cancer clinical, biological, and patient-reported outcomes., Methods: Prostate 8-II is a 4-arm RCT among 200 men with prostate cancer who chose radical prostatectomy (RP) as their primary treatment. Men are enrolled prior to RP and randomized to exercise-only, diet-only, exercise + diet, or usual care (50/arm). Participants begin their assigned intervention 0-5 weeks prior to RP and continue for 24-months following surgery. The 3 active intervention arms receive access to a web-portal and text messages, coaching calls, and other intervention resources (e.g., heart rate sensor and resistance bands and/or recipe booklet). Weekly exercise goals for the exercise intervention groups are 150 min moderate or 75 min vigorous aerobic exercise, 2 strength sessions, and 2 flexibility sessions. Diet intervention groups work with a dietitian to customize their goals (e.g., increase cruciferous vegetables, cooked tomatoes, healthy fats, fish; limit processed meats, whole milk). The primary endpoint is biochemical recurrence. Secondary endpoints include change in tumor biomarkers from biopsy to RP as well as patient-reported outcomes (e.g., quality-of-life), blood and urine biomarkers, and anthropometry at 0, 6, 12, and 24 months., Conclusion: This 4-arm RCT will examine the impact of change in exercise and diet (alone or in combination) on prostate cancer recurrence, biology, and quality-of-life., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: S.A.K is a consultant and board member for Fellow Health Inc., unrelated to the current study.

Background: Wearable sensors could be a simple way to quantify and characterize mobility in patients with hematologic cancer scheduled to receive autologous hematopoietic stem cell transplant (autoHSCT) and how they may be related to common treatment-related symptoms and side effects of induction chemotherapy., Objective: We aimed to conduct a cross-sectional study comparing mobility in patients scheduled to receive autoHSCT with that in healthy, age-matched adult controls and determine the relationships between patient mobility and chemotherapy-related symptoms., Methods: Patients scheduled to receive autoHSCT (78/156, 50%) and controls (78/156, 50%) completed the prescribed performance tests using wearable inertial sensors to quantify mobility including turning (turn duration and number of steps), gait (gait speed, stride time, stride time variability, double support time, coronal trunk range of motion, heel strike angle, and distance traveled), and balance (coronal sway, coronal range, coronal velocity, coronal centroidal frequency, sagittal sway, sagittal range, sagittal velocity, and sagittal centroidal frequency). Patients completed the validated patient-reported questionnaires to assess symptoms common to chemotherapy: chemotherapy-induced peripheral neuropathy (Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity subscale), nausea and pain (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire), fatigue (Patient-Reported Outcomes Measurement Information System Fatigue Short Form 8a), vertigo (Vertigo Symptom Scale-short form), and depression (Center for Epidemiological Studies-Depression). Paired, 2-sided t tests were used to compare mobility between patients and controls. Stepwise multivariable linear regression models were used to evaluate associations between patient mobility and symptoms., Results: Patients aged 60.3 (SD 10.3) years had significantly worse turning (turn duration; P<.001), gait (gait speed, stride time, stride time variability, double support time, heel strike angle, stride length, and distance traveled; all P<.001), and balance (coronal sway; P<.001, range; P<.001, velocity; P=.02, and frequency; P=.02; and sagittal range; P=.008) than controls. In patients, high nausea was associated with worse stride time variability (ß=.001; P=.005) and heel strike angle (ß=-.088; P=.02). Pain was associated with worse gait speed (ß=-.003; P=.003), stride time variability (ß=.012; P=.02), stride length (ß=-.002; P=.004), and distance traveled (ß=-.786; P=.005). Nausea and pain explained 17% to 33% and 14% to 36% of gait variance measured in patients, respectively., Conclusions: Patients scheduled to receive autoHSCT demonstrated worse mobility in multiple turning, gait, and balance domains compared with controls, potentially related in part to nausea and pain. Wearable inertial sensors used in the clinic setting could provide granular information about mobility before further treatment, which may in turn benefit from rehabilitation or symptom management. Future longitudinal studies are needed to better understand temporal changes in mobility and symptoms across the treatment trajectory to optimally time, design, and implement strategies, to preserve functioning in patients with hematologic cancer in the long term., (©Meghan B Skiba, Graham Harker, Carolyn Guidarelli, Mahmoud El-Gohary, Fay Horak, Eric J Roeland, Rebecca Silbermann, Brandon Hayes-Lattin, Kerri Winters-Stone.

Introduction: DailyDose is a decision support system designed to provide real-time dosing advice and weekly insulin dose adjustments for adults living with type 1 diabetes using multiple daily insulin injections. Materials and Methods: Twenty-five adults were enrolled in this single-arm study. All participants used Dexcom G6 for continuous glucose monitoring, InPen for short-acting insulin doses, and Clipsulin to track long-acting insulin doses. Participants used DailyDose on an iPhone for 8 weeks. The primary endpoint was % time in range (TIR) comparing the 2-week baseline to the final 2-week period of DailyDose use. Results: There were no significant differences between TIR or other glycemic metrics between the baseline period compared to final 2-week period of DailyDose use. TIR significantly improved by 6.3% when more than half of recommendations were accepted and followed compared with 50% or fewer recommendations (95% CI 2.5%-10.1%, P  = 0.001). Conclusions: Use of DailyDose did not improve glycemic outcomes compared to the baseline period. In a post hoc analysis, accepting and following recommendations from DailyDose was associated with improved TIR. Clinical Trial Registration Number: NCT04428645.

Purpose/objectives: Cancer treatment survivors often report impaired functioning and increased falls. Not all survivors experience the same symptom burden, suggesting individual susceptibilities. APOE genotype is a potential genetic risk factor for cancer treatment related side effects. Lifestyle factors such as physical activity can mitigate the effect of APOE genotype on measures of clinical interest in individuals without a history of cancer. We tested the hypothesis that APOE genotype influences cancer treatment related side effects and symptoms as well as response to exercise intervention., Materials and Methods: Data from a subsample of a study of fall prevention exercise in post-treatment female cancer survivors aged 50-75 years old (https://clinicaltrials.gov NCT01635413) were used to conduct a secondary data analysis. ApoE genotype was determined by serum sampling. Physical functioning, frequency of falls, and symptom burden were assessed using survey instruments., Results: Data from 126 female cancer survivors a median of 49 months out from cancer diagnosis were analyzed. ApoE4 carriers trended toward a higher fall rate at baseline ( p = 0.059), but after exercise intervention had a fall rate lower than E4 non-carriers both immediately after structured intervention ( p = 0.013) and after 6 months of follow up ( p = 0.002). E2 carriers did not show improved measures of depressive symptoms and self-report disability after exercise intervention. E3 homozygotes showed increased self report physical activity after the 6 month exercise intervention, but E4 and E2 carriers did not., Conclusions: APOE genotype may modulate cancer treatment related side effects and symptoms and response to exercise intervention.

In this study, we assessed the influences of change in moderate-to-vigorous physical activity (MVPA)/sedentary time (ST) of caregivers participating in a commercial weight-loss program on their children's change in MVPA/ST. Data from 29 caregivers and their children were collected over 8 weeks. We used multivariable linear regression to assess associations of changes in caregiver's percent of time spent in MVPA/ST and changes in their child's percent of time spent in MVPA/ST. For caregivers that decreased body mass index (BMI) over 8 weeks, changes in caregivers' MVPA was strongly associated with the change in children's MVPA (β = 2.61 [95% CI: 0.45, 4.77]) compared to caregivers who maintained/increased BMI (β = 0.24 [-2.16, 2.64]). Changes in caregivers' ST was strongly associated with changes in children's ST (β = 2.42 [1.02, 3.81]) compared to caregivers who maintained/increased BMI (β = 0.35 [-0.45, 1.14]). Findings reinforce encouraging caregivers to enroll in weight-loss programs for the benefit of their children as well as for themselves.

Context: Second-generation androgen receptor inhibitors (ARIs) extend metastasis-free survival, prolong overall survival, and delay symptoms when added to androgen deprivation therapy for the treatment of castration-sensitive or castration-resistant prostate cancer (CRPC). However, ARIs may adversely impact physical and cognitive function, thereby decreasing quality of life and prognosis., Objective: To evaluate the evidence regarding the potential effects of ARIs on physical and cognitive function and to contextualize how drug-related adverse effects may influence treatment decisions in CRPC., Evidence Acquisition: We performed a literature search using MEDLINE from January 1998 to June 2020 using terms relating to prostate cancer, androgen deprivation, and physical and cognitive function. We selected 61 publications for analysis., Evidence Synthesis: Treatment-induced deterioration in physical and cognitive function may impair the independence and well-being of patients with CRPC. Patient-reported outcomes from clinical trials of ARIs provide quantitative evidence of their impact on these domains, which appears to vary between ARIs, reflecting the different adverse event profiles of these agents. Thus, the risk of physical or cognitive dysfunction may be managed or mitigated by appropriate selection of treatment options. Studies in patients with CRPC have assessed the cognitive effects of ARIs with validated instruments, whereas quantitative analysis of the impact on physical function has been limited., Conclusion: Several validated instruments utilized for the assessment of physical and cognitive function in clinical studies have been adapted for clinical practice; however, consensus on the standardization of these assessments is required. Future clinical studies employing validated tools may generate data on the impact of ARIs and guide treatment decisions for patients with CRPC., Patient Summary: We review the hormonal therapies used to treat men with prostate cancer and the effects they have on physical and cognitive function.

Background: This study examines the feasibility, acceptability, and safety of a newly developed cognitive-enhancing Tai Ji Quan training intervention, delivered via remote videoconferencing, for older adults with mild cognitive impairment (MCI)., Methods: In a three-arm feasibility trial, community-dwelling older adults with MCI (N = 69; mean age = 74.6 years, 57% women) were randomized to a cognitively enhanced Tai Ji Quan (n = 23), standard Tai Ji Quan (n = 22), or stretching group (n = 24) and participated in a 60-minute online exercise session via Zoom, twice weekly for 16 weeks. Participants were recruited primarily in the state of Oregon through mass mailing and word of mouth. The primary outcomes were intervention feasibility (with respect to recruitment, online intervention delivery, fidelity and compliance, and attrition and retention rates), acceptability, and safety. We also assessed feasibility of online data collection and test-retest reliability and explored preliminary trends on secondary outcomes that included global cognitive function, dual-task cost, and domain-specific cognition function., Results: The study had an average recruitment rate of 55%. Feasibility was demonstrated by the overall successful online program implementation, with good fidelity, acceptable compliance (76%), and excellent retention (94%). The cognitively enhanced Tai Ji Quan intervention was shown to be acceptable to participants as well as safe, with no major intervention-related moderate/severe events. At week 16, the group receiving cognitively enhanced Tai Ji Quan training showed a positive trend in the cognitive function and dual-task outcome measures whereas the group receiving standard Tai Ji Quan training exhibited positive trends on global and domain-specific cognitive measures., Conclusions: Preliminary findings of this pilot study indicate the feasibility, acceptability, and safety of a tailored, cognitively enhanced Tai Ji Quan training intervention delivered remotely to home settings via videoconferencing for community-dwelling older adults with MCI., Trial Registration: Clinicaltrials.gov identifier NCT04070703., (© 2022.

To manage acute, long-term, and late effects of cancer, current guidelines recommend moderate-to-vigorous intensity aerobic and resistance exercise. Unfortunately, not all cancer survivors are able or willing to perform higher intensity exercise during difficult cancer treatments or because of other existing health conditions. Tai Chi is an equipment-free, multicomponent mind-body exercise performed at light-to-moderate intensity that may provide a more feasible alternative to traditional exercise programs for some cancer survivors. This systematic review evaluated the therapeutic efficacy of Tai Chi across the cancer care continuum. We searched MEDLINE/PubMed, Embase, SCOPUS, and CINAHL databases for interventional studies from inception to 18 September 2020. Controlled trials of the effects of Tai Chi training on patient-reported and objectively measured outcomes in cancer survivors were included. Study quality was determined by the RoB 2 tool, and effect estimates were evaluated using the Best Evidence Synthesis approach. Twenty-six reports from 14 trials (one non-randomized controlled trial) conducted during (n = 5) and after treatment (after surgery: n = 2; after other treatments: n = 7) were included. Low-level evidence emerged to support the benefits of 40-60 min of thrice-weekly supervised Tai Chi for 8-12 weeks to improve fatigue and sleep quality in cancer survivors. These findings need to be confirmed in larger trials and tested for scaling-up potential. Insufficient evidence was available to evaluate the effects of Tai Chi on other cancer-related outcomes. Future research should examine whether Tai Chi training can improve a broader range of cancer outcomes including during the pre-treatment and end of life phases., (© 2021 The Authors.

Background: Although women with heart failure (HF) are potentially more likely to be physically frail compared with men with HF, the underlying contributors to this sex difference are poorly understood. The purpose of this study was to characterize sex differences in physical frailty phenotypes in HF., Methods: We prospectively enrolled adults with class I-IV HF. Physical frailty was measured with the frailty phenotype criteria. Symptoms of dyspnea, sleep-related impairment, pain interference, depression, and anxiety were assessed. Body composition was measured using dual-energy x-ray absorptiometry. Simple comparative statistics and stepwise regression modeling were used., Results: The average age of the sample (n=115) was 63.6±15.7 years, 49% were women, and 73% had nonischemic cause. Forty-three percent of the sample was physically frail. Women had a 4.6 times greater odds of being physically frail compared with men, adjusting for covariates (odds ratio=4.63 [95% CI, 1.81-11.84], P =0.001). Both physically frail men and women were characterized by more type 2 diabetes, higher comorbidity burden, and worse dyspnea symptoms. Physically frail women had significantly worse symptoms compared with non-physically frail women but no difference in body composition characteristics. Physically frail men had significantly lower appendicular muscle mass, higher percent fat, lower hemoglobin, and more depressive symptoms compared with non-physically frail men., Conclusions: Women are significantly more likely to be physically frail compared with men in HF. Physical frailty in both women and men is characterized by comorbidities and worse symptoms; physical frailty in men is characterized by worse physiological characteristics.

Objective: Patients with lung cancer experience significant declines in psychosocial and physical function during and after treatment that impact quality of life (QOL) and survival. Yoga is a potential strategy to mitigate functional decline among patients with lung cancer., Methods: A single group 12-week pilot trial of low-moderate intensity yoga among patients with stage I-IV lung cancer and their partners (n = 46; 23 patient-partner dyads) during cancer treatment from two hospital systems. Feasibility, acceptability, descriptive statistics, and Cohen d effect sizes were calculated at 6 and 12-weeks for psychosocial and physical outcomes using validated questionnaires and assessments., Results: At 6 and 12-weeks, retention was 65% and withdrawals were mainly due to disease progression. Among study completers (n = 26; 13 dyads) adherence was 80%. Comparing baseline to 12-week measurements, fatigue, depression symptoms, and sleep disturbance improved in 54% of participants for all three measures (Cohen's d = 0.40-0.53). QOL improved in 77% of participants (Cohen's d = 0.34). Upper and lower body flexibility, and lower body strength improved in 92%, 85% and 77% of participants, respectively (Cohen's d = 0.39-1.08). Six-minute walk test improved in 62% of participants an average of 32 meters (SD = 11.3; Cohen's d = 0.17). No serious adverse events were reported., Conclusions: Among patients with stage I-IV lung cancer including active treatment, a 12-week partner-supported yoga program is feasible, acceptable, and improved psychosocial and physical function. Low-intensity yoga may be a complimentary approach to reduce the effects of cancer treatment, however, more research is needed to determine the efficacy of partner-supported yoga to mitigate functional decline., (© 2021 John Wiley & Sons Ltd.)

Objectives: Sedentary behavior is pervasive in the workplace and is harmful to health. Research on the effectiveness of comprehensive workplace interventions to reduce sedentary behavior and improve worker health and safety is crucial as sedentary jobs become more common., Methods: We developed a Total Worker Health intervention targeting sedentary behavior in call centers, and are evaluating intervention effectiveness in a randomized controlled trial. Four worksites will be randomly assigned to an intervention or control condition. The intervention condition includes the provision of active workstations along with programs and procedures at environmental, organizational, and individual levels. Control worksites will receive active workstations with no additional support, following common organizational practices., Results: Outcomes include objectively measured physical activity, biological markers of health, and self-report survey data at baseline, after the 6-month intervention or control period, and at a 12-month follow-up., Conclusions: The aims of the study are to determine whether a Total Worker Health intervention has stronger impacts on workplace sedentary behavior, uninterrupted bouts of sitting, and worker health and safety compared to a usual practice control condition. The study will inform future workplace sedentary behavior intervention and dissemination research, along with organizational best practices for reducing sedentary behavior in the workplace., (Copyright © 2021 Elsevier Inc.
