RESUMO
BACKGROUND: Structured exercise has an important role in mitigating the extensive side effects caused by ongoing prostate cancer treatments, specifically androgen deprivation therapy (ADT) and radiation therapy (RT). Little is known about men's experiences of, and preferences for, structured exercise programmes during active cancer treatment. This study aimed to inform the acceptability of a 6-month supervised intervention that emphasised increasing and varied intensities of aerobic and resistance exercise, by exploring the experiences of men who participated. METHODS: Individual semi-structured interviews were conducted with an interviewer independent of the exercise study and data was analysed using a descriptive qualitative design. RESULTS: Twelve prostate cancer patients were interviewed including participants who completed (n = 9) and withdrew from (n = 3) the intervention. Four main themes captured how men experienced the intervention: (1) Navigating the Unknown: Building confidence amidst vulnerability (subtheme- pushing the limits), (2) Building Trust: The credibility and approach of the exercise instructor (subtheme- appropriateness of supervised vs. independent exercise), (3) Flexibility in Delivery, (4) Finding Purpose: Exercise as a means of escapism and regaining control during treatment. CONCLUSION: While an initial lack of self-confidence can be a barrier to exercise participation, exercise programmes have the potential to provide psychosocial benefits, rebuild confidence and empower men throughout their cancer treatment and into recovery. Structured exercise is acceptable during treatment including RT and can offer a form of escapism and sense of control for men navigating their cancer journey. Trust building, flexible delivery and credibility alongside a challenging exercise prescription are important facilitators of acceptability for men. Strategies to embed exercise from the point of diagnosis through ADT and RT should reflect men's experiences of exercise during treatment. TRIAL REGISTRATION: The trial has been registered on ClinicalTrials.gov as of the 14th of December 2021 (NCT05156424).

PURPOSE: Cancer survivors physical function response to exercise programs at the group level is well-established. However, to advance toward a more personalized approach in exercise oncology, a greater understanding of individual response is needed. This study utilized data from a well-established cancer-exercise program to evaluate the heterogeneity of physical function response and explore characteristics of participants who did vs. did not achieve a minimal clinically important difference (MCID). METHODS: Physical function measures (grip strength, 6-min walk test (6MWT), and sit-to-stand) were completed pre/post the 3-month program. Change scores for each participant and the proportion achieving the MCID for each physical function measure were calculated. The independent t-tests, Fisher's exact test, and decision tree analyses were used to explore differences in age, body mass index (BMI), treatment status, exercise session attendance, and baseline value between participants who achieved the MCID vs. those who did not. RESULTS: Participants (N = 250) were 55 ± 14 years old, majority female (69.2%), white (84.1%), and diagnosed with breast cancer (36.8%). Change in grip strength ranged from - 42.1 to + 47.0 lb, and 14.8% achieved the MCID. Change in 6MWT ranged from - 151 to + 252 m, and 59% achieved the MCID. Change in sit-to-stand ranged from - 13 to + 20 reps, and 63% achieved the MCID. Baseline grip strength, age, BMI, and exercise session attendance were related to achieving MCID. CONCLUSIONS: Findings illustrate wide variability in the magnitude of cancer survivors' physical function response following an exercise program, and that a variety of factors predict response. Further investigation into the biological, behavioral, physiological, and genetic factors will inform tailoring of exercise interventions and programs to maximize the proportion of cancer survivors who can derive clinically meaningful benefits.

Funding communities through mini-grant programs builds community capacity by fostering leadership among community members, developing expertise in implementing evidence-based practices, and increasing trust in partnerships. The South Carolina Cancer Prevention and Control Research Network (SC-CPCRN) implemented the Community Health Intervention Program (CHIP) mini-grants initiative to address cancer-related health disparities among high-risk populations in rural areas of the state. One community-based organization and one faith-based organization were funded during the most recent call for proposals. The organizations implemented National Cancer Institute evidence-based strategies and programs focused on health and cancer screenings and physical activity and promotion of walking trails. Despite the potential for the COVID-19 pandemic to serve as a major barrier to implementation, grantees successfully recruited and engaged community members in evidence-based activities. These initiatives added material benefits to their local communities, including promotion of walking outdoors where it is less likely to contract the virus when socially distanced and provision of COVID-19 testing and vaccines along with other health and cancer screenings. Future mini-grants programs will benefit from learning from current grantees' flexibility in program implementation during a pandemic as well as their intentional approach to modifying program aspects as needed.

Background: Although androgen-deprivation therapy (ADT) is the foundation of treatment for prostate cancer, the physiological impacts of ADT result in functional decline and enhanced risk of chronic disease and metabolic syndrome. Purpose: The Individualized Diet and Exercise Adherence Pilot Trial (IDEA-P) is a single-blind, randomized, pilot trial comparing the effects of a group-mediated, cognitive-behavioral (GMCB) exercise and dietary intervention (EX+D) with those of a standard-of-care (SC) control during the treatment of prostate cancer patients undergoing ADT. Methods: A total of 32 prostate cancer patients (M age = 66.28, SD = 7.79) undergoing ADT were randomly assigned to the 12-week EX+D intervention (n = 16) or control (n = 16). The primary outcome in IDEA-P was change in mobility performance with secondary outcomes including body composition and muscular strength. Blinded assessment of outcomes were obtained at baseline and at 2- and 3-month follow-ups. Results: Favorable adherence and retention rates were observed, and no serious intervention-related adverse events were documented. Intent-to-treat ANCOVA controlling for baseline value and ADT duration demonstrated that EX+D resulted in significantly greater improvements in mobility performance (p < .02), muscular strength (p < .01), body fat percentage (p < .05), and fat mass (p < .03) at 3-month follow-up, relative to control. Conclusion: Findings from the IDEA-P trial suggest that a GMCB-based EX+D intervention resulted in significant, clinically meaningful improvements in mobility performance, muscular strength, and body composition, relative to controls. Collectively, these results suggest that the EX+D was a safe and well-tolerated intervention for prostate cancer patients on ADT. The utility of implementing this approach in the treatment of prostate cancer patients on ADT should be evaluated in future large-scale efficacy trials. Clinical Trial information: NCT02050906.

Fairman, CM, LaFountain, RL, Lucas, AR, and Focht, BC. Monitoring resistance exercise intensity using ratings of perceived exertion (RPE) in previously untrained patients with prostate cancer undergoing androgen deprivation therapy. J Strength Cond Res 32(5): 1360-1365, 2018-Exercise has been shown to be safe and effective for patients with prostate cancer (PrCa). The monitoring of resistance exercise (RE) intensity is an emerging area of interest in RE prescription. Rating of perceived exertion (RPE) is one of the most commonly used methods but has not yet been validated in this population. Thus, the purpose of this study was to examine the relationship between RPE and RE intensity in PrCa. Data for this study were abstracted from baseline upper- and lower-body strength assessments from 2 previous trials (Individual Diet and Exercise Adherence Pilot Trial; Livestrong, Austin, TX, USA) in our laboratory investigating functional outcomes in patients with PrCa undergoing androgen deprivation therapy (ADT). A total of 75 participants from both trials were included in this study. Ratings of perceived exertion corresponding to 50, 70, and 90% 1 repetition maximum (1RM) were extracted from the results of participants' upper- and lower-body 1RM strength tests. The changes in RPE across increasing intensities were assessed using separate univariate analysis of variance (ANOVA). For each ANOVA, RPE was used as the dependent variable and intensity (50, 70, and 90%) used as the fixed factor. A univariate ANOVA revealed a significant difference (p ≤ 0.05) among the RPE values for each intensity for both upper- and lower-body lifts. The results of our analyses suggest that RPE values rise linearly in response to increases in exercise intensity. Our study supports the concept that RPE may be a practical training tool to accurately estimate RE intensity in PrCa survivors undergoing ADT. Practitioners may consider using RPE to monitor and adjust RE intensity in this population.

The objective of the present study was to compare a group-mediated cognitive behavioral (GMCB) physical activity intervention with traditional exercise therapy (TRAD) upon select social cognitive outcomes in sedentary knee osteoarthritis (knee OA) patients. A total of 80 patients (mean age = 63.5 years; 84% women) were recruited using clinic and community-based strategies to a 12-month, single-blind, two-arm, randomized controlled trial. Mobility-related self-efficacy, self-regulatory self-efficacy (SRSE), and satisfaction with physical function (SPF) were assessed at baseline, 3, and 12 months. Results of intent-to-treat 2 (Treatment: GMCB and TRAD) × 2 (Time: 3 and 12 month) analyses of covariance yielded significantly greater increases in SRSE and SPF (P < 0.01) relative to TRAD. Partial correlations revealed that changes in SRSE and SPF were significantly related (P < 0.05) to improvements in physical activity and mobility at 3 and 12-months. The GMCB intervention yielded more favorable effects on important social cognitive outcomes than TRAD; these effects were related to improvements in physical activity and mobility.

Cotter, JA, Garver, MJ, Dinyer, TK, Fairman, CM, and Focht, BC. Ratings of perceived exertion during acute resistance exercise performed at imposed and self-selected loads in recreationally trained women. J Strength Cond Res 31(8): 2313-2318, 2017-Resistance exercise (RE) is commonly used to elicit skeletal muscle adaptation. Relative intensity of a training load links closely with the outcomes of regular RE. This study examined the rating of perceived exertion (RPE) responses to acute bouts of RE using imposed (40% and 70% of 1 repetition maximum [1RM]) and self-selected (SS) loads in recreationally trained women. Twenty physically active women (23.15 ± 2.92 years), who reported regular RE training of at least 3 weekly sessions for the past year, volunteered to participate. During the initial visit, participants completed 1RM testing on 4 exercises in the following order: leg extension, chest press, leg curl, and lat pull-down. On subsequent visits, the same exercises were completed at the SS or imposed loads. The RPE was assessed after the completion of each set of exercises during the 3 RE conditions using the Borg-15 category scale. Self-selected loads corresponded to an average of approximately 57%1RM (±7.62). Overall, RPE increased with load (40%1RM = 11.26 [±1.95]; SS 57%1RM = 13.94 [±1.58]; and, 70%1RM = 15.52 [±2.05]). Reflecting the linear pattern found between load and perceived effort, the present data provide evidence that RPE levels less than 15 likely equate to loads which are not consistent with contemporary American College of Sports Medicine (ACSM) guidelines for enhancing musculoskeletal health which includes strength and hypertrophy. Women desiring increases in strength and lean mass likely need to train at an exertion level at or surpassing a rating of 15 on the Borg-15 category. This article examined the modification of training load on perceived exertion, but other variables, such as the number of repetitions completed, may also be targeted to achieve a desired RPE. The primary understanding is that women who engage in RE may not self-select loads that are consistent with the ACSM recommendations for musculoskeletal health.

Hyde, PN, Kendall, KL, Fairman, CM, Coker, NA, Yarbrough, ME, and Rossi, SJ. Utilization of B-mode ultrasound as a body fat estimate in collegiate football players. J Strength Cond Res 30(12): 3525-3530, 2016-The purpose of the present study was to validate a 7-site ultrasound imaging protocol to predict the percent body fat (%BF) in a division I football team. Body composition was estimated by ultrasound, 7-site skinfolds, and the 3-compartment-water (3C-W) model of Siri, using bioimpedance spectroscopy to estimate the total body water and air displacement plethysmography (using BODPOD) to determine the body density. Pearson's product-moment correlation analyses were run to determine correlations between ΣUltrasound and the criterion 3C-W, and between the ΣSkinfold and ΣUltrasound. Strong positive correlations were observed between ΣSkinfold and ΣUltrasound (r = 0.984; p < 0.001). Furthermore, a strong positive correlation was observed between ΣUltrasound and %BF from 3C-W (r = 0.878; p < 0.001). Based on the significant correlation analysis, a linear regression equation was developed to predict the %BF from ΣUltrasound, using %BF from the 3C-W model as the dependent variable: %BF = 6.194 + (0.096 × ΣUltrasound); standard error of the estimate (SEE) = 2.97%. Cross-validation analyses were performed using an independent sample of 29 players. The mean observed %BF from the 3C-W model and the mean predicted %BF were 18.32 ± 6.26% and 18.78 ± 6.22%, respectively. The constant error, SEE, and validity coefficient (r) were 0.87%, 2.64%, and 0.91%, respectively. The total error was 2.87%. The positive relationship between ultrasound measurements and the 3C-W model suggests that ultrasound imaging may be a practical alternative to predicting %BF in division I football players.

The purpose of this study was to examine the affective responses to acute resistance exercise (RE) performed at self-selected (SS) and imposed loads in recreationally trained women. Secondary purposes were to (a) examine differences in correlates of motivation for future participation in RE and (b) determine whether affective responses to RE were related to these select motivational correlates of RE participation. Twenty recreationally trained young women (mean age = 23 years) completed 3 RE sessions involving 3 sets of 10 repetitions using loads of 40% of 1 repetition maximum (1RM), 70% 1RM, and an SS load. Affective responses were assessed before, during, and after each RE session using the Feeling Scale. Self-efficacy and intention for using the imposed and SS loads for their regular RE participation during the next month were also assessed postexercise. Results revealed that although the SS and imposed load RE sessions yielded different trajectories of change in affect during exercise (p < 0.01), comparable improvements in affect emerged after RE. Additionally, the SS condition was associated with the highest ratings of self-efficacy and intention for future RE participation (p < 0.01), but affective responses to acute RE were unrelated to self-efficacy or intention. It is concluded that acute bouts of SS and imposed load RE resulted in comparable improvements in affect; recreationally trained women reported the highest self-efficacy and intention to use the load chosen in SS condition in their own resistance training; and affective responses were unrelated to motivational correlates of resistance training.

Social media usage has soared in the last decade, with the majority of adults having an account on at least one platform. Sites such as LinkedIn, X, and TikTok allow users to share content using different forms, for example, written or video, long form or short form. Social media can be used by researchers to forge collaborations, rapidly disseminate new research, and demonstrate societal impact. This opinion piece aims to highlight the value of social media, in particular for early career researchers, and offer suggestions on how early career researchers can strategically use social media to build a network and an online presence. We reflect on our own experiences of social media and include some of the reasons we have been deterred from it in the past, such as fear of making a mistake, being misunderstood, or painted as being an overconfident "know it all." As the demonstration of impact and engagement becomes ever more important in grant applications and job security, social media competency is a powerful professional skill that will be important for all scientists.

BACKGROUND: Those with intermediate and high-risk prostate cancer typically receive androgen deprivation therapy (ADT) as part of their treatment. ADT often results in extensive side effects including increased risk of cardiometabolic disease. Many ADT side effects can be influenced by exercise, both resistance and aerobic training. Exercise regimes typically combine aerobic and resistance exercise but the appropriate emphasis for achieving the broadest range of therapeutic benefits has yet to be determined. We propose to determine the feasibility of undertaking a larger trial comparing a resistance- vs an aerobic-emphasised exercise intervention in men with prostate cancer undergoing ADT. The trial will also investigate preliminary evidence of difference between arms for cardiometabolic health and quality of life outcomes. METHODS: This is a 6-month randomised two-armed feasibility trial. Prostate cancer patients undergoing ADT and radiotherapy will be recruited (n = 24) and randomised to either a resistance- or aerobic-emphasised group. Participants will attend twice-weekly supervised individual or small group sessions, with 75% of exercise time in the primary exercise modality. The primary outcome will be feasibility, determined via assessment of recruitment, retention, adherence, safety, and acceptability. Secondary outcomes will include quality of life, body composition, vascular indices, aerobic and muscular fitness and cardiometabolic health blood biomarkers. CONCLUSION: It is envisaged that the trial will provide valuable information and preliminary difference data that will aid in the design of an efficacious larger trial that will adopt a major and minor emphasis approach to the scheduling of resistance and aerobic exercise.

Breast cancer (BC) is one of the most common cancers in the United States. Advances in detection and treatment have resulted in an increased survival rate, meaning an increasing population experiencing declines in muscle mass and strength. Creatine supplementation has consistently demonstrated improvements in strength and muscle performance in older adults, though these findings have not been extended to cancer populations. PURPOSE: The purpose of this study was to investigate the effects of short-term creatine supplementation on muscular performance in BC survivors. METHODS: Using a double-blind, placebo-controlled, randomized design, 19 female BC survivors (mean ± SD age = 57.63 ± 10.77 years) were assigned to creatine (SUPP) (n = 9) or dextrose placebo (PLA) (n = 10) groups. The participants completed two familiarization sessions, then two test sessions, each separated by 7 days, where the participants supplemented with 5 g of SUPP or PLA 4 times/day between sessions. The testing sessions included sit-to-stand power, isometric/isokinetic peak torque, and upper/lower body strength via 10 repetition maximum (10RM) tests. The interaction between supplement (SUPP vs. PLA) and time (Pre vs. Post) was examined using a group × time ANOVA and effect sizes. RESULTS: No significant effects were observed for sit-to-stand power (p = 0.471; ηp2 = 0.031), peak torque at 60°/second (p = 0.533; ηp2 = 0.023), peak torque at 120°/second (p = 0.944; ηp2 < 0.001), isometric peak torque (p = 0.905; ηp2 < 0.001), 10RM chest press (p = 0.407; ηp2 = 0.041), and 10RM leg extension (p = 0.932; ηp2 < 0.001). However, a large effect size for time occurred for the 10RM chest press (ηp2 = 0.531) and leg extension (ηp2 = 0.422). CONCLUSION: Seven days of creatine supplementation does not influence muscular performance among BC survivors.

Background: Cancer remains a leading cause of death worldwide and continues to disproportionately impact certain populations. Several frameworks have been developed that illustrate the multiple determinants of cancer. Expanding upon the work of others, we present an applied framework for cancer prevention and control designed to help clinicians, as well as public health practitioners and researchers, better address differences in cancer outcomes. Methods: The framework was developed by the Cancer Prevention and Control Research Network's Health Behaviors Workgroup. An initial framework draft was developed based on workgroup discussion, public health theory, and rapid literature review on the determinants of cancer. The framework was refined through interviews and focus groups with Federally Qualified Health Center providers (n=2) and cancer patients (n=2); participants were asked to provide feedback on the framework's causal pathways, completeness, and applicability to their work and personal life. Results: The framework provides an overview of the relationships between sociodemographic inequalities, social and structural determinants, and key risk factors associated with cancer diagnosis, survivorship, and cancer morbidity and mortality across the lifespan. The framework emphasizes how health-risk behaviors like cigarette smoking interact with psychological, psychosocial, biological, and psychosocial risk factors, as well as healthcare-related behavior and other chronic diseases. Importantly, the framework emphasizes addressing social and structural determinants that influence health behaviors to reduce the burden of cancer and improve health equity. Aligned with previous theory, our framework underscores the importance of addressing co-occurring risk factors and disease states, understanding the complex relationships between factors that influence cancer, and assessing how multiple forms of inequality or disadvantage intersect to increase cancer risk across the lifespan. Conclusions: This paper presents an applied framework for cancer prevention and control to address cancer differences. Because the framework highlights determinants and factors that influence cancer risk at multiple levels, it can be used to inform the development, implementation, and evaluation of interventions to address cancer morbidity and mortality.
RESUMO
BACKGROUND: Exercise intervention research has shown promising results in preventing and reversing the side effects caused by prostate cancer and its' treatment. However, there are still unanswered questions and the need for additional research. As the field of exercise oncology in the context of prostate cancer presents unique challenges and complexities, seeking the advice of experienced exercise oncology researchers before initiating a similar trial could help to design more effective and efficient studies and help avoid pitfalls. METHODS: A qualitative descriptive study design and a nonprobability, purposive sampling method was employed. An interview guide was developed and included topics such as recruitment, retention, programme goals, research design, health considerations, treatment considerations, adverse events, exercise prescription and outcome tools. Individual semi-structured interviews were conducted and interviews were transcribed and analysed using thematic analysis. RESULTS: Eight individuals with extensive experience working with prostate cancer patients in exercise oncology research settings were interviewed. Four main themes and seven subthemes were generated and supported by the data. Theme 1 highlighted the critical role of recruitment, with associated subthemes on recruitment barriers and recruitment methods. Theme 2 explored the positives and negatives of home-based programmes. Theme 3 focused on specific health characteristics, exercise prescription and outcome measure factors that must be considered when working with prostate cancer cohorts. Finally, theme 4 centered around the emotional dimensions present in exercise oncology trials, relating to both researchers and study participants. CONCLUSION: Exercise oncology remains a challenging area in which to conduct research. Learning from experienced personnel in the field offers valuable information and guidance that could impact the success of future trials.
RESUMO
Background: Exercise is recommended for people with cancer. The aim of this study was to evaluate the harms of exercise in patients with cancer undergoing systemic treatment. Methods: This systematic review and meta-analysis included published and unpublished controlled trials comparing exercise interventions versus controls in adults with cancer scheduled to undergo systemic treatment. The primary outcomes were adverse events, health-care utilization, and treatment tolerability and response. Eleven electronic databases and trial registries were systematically searched with no date or language restrictions. The latest searches were performed on April 26, 2022. The risk of bias was judged using RoB2 and ROBINS-I, and the certainty of evidence for primary outcomes was assessed using GRADE. Data were statistically synthesised using pre-specified random-effect meta-analyses. The protocol for this study was registered in the PROESPERO database (ID: CRD42021266882). Findings: 129 controlled trials including 12,044 participants were eligible. Primary meta-analyses revealed evidence of a higher risk of some harms, including serious adverse events (risk ratio [95% CI]: 1.87 [1.47-2.39], I2 = 0%, n = 1722, k = 10), thromboses (risk ratio [95% CI]: 1.67 [1.11-2.51], I2 = 0%, n = 934, k = 6), and fractures (risk ratio [95% CI]: 3.07 [3.03-3.11], I2 = 0%, n = 203, k = 2) in intervention versus control. In contrast, we found evidence of a lower risk of fever (risk ratio [95% CI]: 0.69 [0.55-0.87], I2 = 0% n = 1109, k = 7) and a higher relative dose intensity of systemic treatment (difference in means [95% CI]: 1.50% [0.14-2.85], I2 = 0% n = 1110, k = 13) in intervention versus control. For all outcomes, we downgraded the certainty of evidence due to imprecision, risk of bias, and indirectness, resulting in very low certainty of evidence. Interpretation: The harms of exercise in patients with cancer undergoing systemic treatment are uncertain, and there is currently insufficient data on harms to make evidence-based risk-benefits assessments of the application of structured exercise in this population. Funding: There was no funding for this study.
RESUMO
Background: Breast cancer survivors (BCS) with overweight or obesity are at heightened risk of cancer recurrence, cardiometabolic disease, and compromised quality of life. Given the prevalence of significant weight gain during and following breast cancer treatment, there is growing recognition of the need to develop efficacious, widely-accessible, weight management programs for BCS. Unfortunately, access to evidence-based weight management resources for BCS remains limited and little is known of the optimal theoretical basis, program components, and mode of delivery for community-based interventions. The primary aim of the Healthy New Albany Breast Cancer (HNABC) pilot trial was to determine the safety, feasibility, and preliminary efficacy of delivering a translational, evidence-based, and theory-driven lifestyle weight management intervention to BCS with overweight or obesity in the community setting. Methods: HNABC was a single-arm, pilot trial evaluating a 24-week, multi-component intervention leveraging exercise, dietary modification, and group-mediated cognitive behavioral (GMCB) counseling components designed to facilitate lifestyle behavior change and promote sustained independent adherence. Assessments of various objectively-determined and patient-reported outcomes and theory-derived determinants of behavioral adoption and maintenance were obtained at baseline, 3- and 6-month follow-up. Measures of trial feasibility were calculated prospectively throughout the study. Conclusion: Findings from the HNABC pilot trial will provide evidence demonstrating the feasibility and preliminary efficacy of a multi-component, community-based, GMCB lifestyle weight management intervention for BCS. Results will inform the design of a future, large-scale, randomized controlled efficacy trial. If successful, this approach could offer a widely accessible, community-based intervention model for weight management programs in BCS.
RESUMO
Introduction: Cancer rates increase with age, and older cancer survivors have unique medical care needs, making assessment of health status and identification of appropriate supportive resources key to delivery of optimal cancer care. Comprehensive geriatric assessments (CGAs) help determine an older person's functional capabilities as cancer care providers plan treatment and follow-up care. Despite its proven utility, research on implementation of CGA is lacking. Methods: Guided by a qualitative description approach and through interviews with primary care providers and oncologists, our goal was to better understand barriers and facilitators of CGA use and identify training and support needs for implementation. Participants were identified through Cancer Prevention and Control Research Network partner listservs and a national cancer and aging organization. Potential interviewees, contacted via email, were provided with a description of the study purpose. Eight semi-structured interviews were conducted via Zoom, recorded, and transcribed verbatim by a professional transcription service. The interview guide explored providers' knowledge and use of CGAs. For codebook development, three representative transcripts were independently reviewed and coded by four team members. The interpretive process involved reflecting, transcribing, coding, and searching for and identifying themes. Results: Providers shared that, while it would be ideal to administer CGAs with all new patients, they were not always able to do this. Instead, they used brief screening tools or portions of CGAs, or both. There was variability in how CGA domains were assessed; however, all considered CGAs useful and they communicated with patients about their benefits. Identified facilitators of implementation included having clinic champions, an interdisciplinary care team to assist with implementation and referrals for intervention, and institutional resources and buy-in. Barriers noted included limited staff capacity and competing demands on time, provider inexperience, and misaligned institutional priorities. Discussion: Findings can guide solutions for improving the broader and more systematic use of CGAs in the care of older cancer patients. Uptake of processes like CGA to better identify those at risk of poor outcomes and intervening early to modify treatments are critical to maximize the health of the growing population of older cancer survivors living through and beyond their disease.
RESUMO
The overall goal of the annual Transdisciplinary Research in Energetics and Cancer (TREC) Training Workshop is to provide transdisciplinary training for scientists in energetics and cancer and clinical care. The 2022 Workshop included 27 early-to-mid career investigators (trainees) pursuing diverse TREC research areas in basic, clinical, and population sciences. The 2022 trainees participated in a gallery walk, an interactive qualitative program evaluation method, to summarize key takeaways related to program objectives. Writing groups were formed and collaborated on this summary of the 5 key takeaways from the TREC Workshop. The 2022 TREC Workshop provided a targeted and unique networking opportunity that facilitated meaningful collaborative work addressing research and clinical needs in energetics and cancer. This report summarizes the 2022 TREC Workshop's key takeaways and future directions for innovative transdisciplinary energetics and cancer research.

Sarcopenia refers to the age-related reduction in strength, muscle mass and functionality which increases the risk for falls, injuries and fractures. Sarcopenia is associated with other age-related conditions such as osteoporosis, frailty and cachexia. Identifying treatments to overcome sarcopenia and associated conditions is important from a global health perspective. There is evidence that creatine monohydrate supplementation, primarily when combined with resistance training, has favorable effects on indices of aging muscle and bone. These musculoskeletal benefits provide some rationale for creatine being a potential intervention for treating frailty and cachexia. The purposes of this narrative review are to update the collective body of research pertaining to the effects of creatine supplementation on indices of aging muscle and bone (including bone turnover markers) and present possible justification and rationale for its utilization in the treatment of frailty and cachexia in older adults.
