Multiphasic exercise prehabilitation for patients undergoing surgery for head and neck cancer: a hybrid effectiveness-implementation study protocol. Support Care Cancer 2023; 31:726. [PMID: 38012345 DOI: 10.1007/s00520-023-08164-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Accepted: 11/06/2023] [Indexed: 11/29/2023]
Abstract
Head and neck cancer (HNC) treatment often consists of major surgery followed by adjuvant therapy, which can result in treatment-related side effects, decreased physical function, and diminished quality of life. Perioperative nutrition interventions and early mobilization improve recovery after HNC treatment. However, there are few studies on prehabilitation that include exercise within the HNC surgical care pathway. We have designed a multiphasic exercise prehabilitation intervention for HNC patients undergoing surgical resection with free flap reconstruction. We will use a hybrid effectiveness-implementation study design guided by the RE-AIM framework to address the following objectives: (1) to evaluate intervention benefits through physical function and patient-reported outcome assessments; (2) to determine the safety and feasibility of the prehabilitation intervention; (3) to evaluate the implementation of exercise within the HNC surgical care pathway; and (4) to establish a post-operative screening and referral pathway to exercise oncology resources. The results of this study will provide evidence for the benefits and costs of a multiphasic exercise prehabilitation intervention embedded within the HNC surgical care pathway. This paper describes the study protocol design, multiphasic exercise prehabilitation intervention, planned analyses, and dissemination of findings.

Abstract
Importance Head and neck cancer-associated lymphedema (HNCaL) affects up to 90% of survivors of head and neck cancer and is a substantial contributor to disability following head and neck cancer treatment. Despite the prevalence and morbidity associated with HNCaL, rehabilitation interventions are not well studied. Objective To identify and appraise the current evidence for rehabilitation interventions in HNCaL. Evidence Review Five electronic databases were searched systematically from inception to January 3, 2023, for studies on HNCaL rehabilitation interventions. Study screening, data extraction, quality rating, and risk of bias assessment were performed by 2 independent reviewers. Findings Of 1642 citations identified, 23 studies (1.4%; n = 2147 patients) were eligible for inclusion. Six studies (26.1%) were randomized clinical trials (RCTs) and 17 (73.9%) were observational studies. Five of the 6 RCTs were published during 2020 to 2022. Most studies had fewer than 50 participants (5 of 6 RCTs; 13 of 17 observational studies). Studies were categorized by intervention type, including standard lymphedema therapy (11 studies [47.8%]) and adjunct therapy (12 studies [52.2%]). Lymphedema therapy interventions included standard complete decongestive therapy (CDT) (2 RCTs, 5 observational studies), modified CDT (3 observational studies), therapy setting (1 RCT, 2 observational studies), adherence (2 observational studies), early manual lymphatic drainage (1 RCT), and inclusion of focused exercise (1 RCT). Adjunct therapy interventions included advanced pneumatic compression devices (APCDs) (1 RCT, 5 observational studies), kinesio taping (1 RCT), photobiomodulation (1 observational study), acupuncture/moxibustion (1 observational study), and sodium selenite (1 RCT, 2 observational studies). Serious adverse events were either not found (9 [39.1%]) or not reported (14 [60.9%]). Low-quality evidence suggested the benefit of standard lymphedema therapy, particularly in the outpatient setting and with at least partial adherence. High-quality evidence was found for adjunct therapy with kinesio taping. Low-quality evidence also suggested that APCDs may be beneficial. Conclusions and Relevance The results of this systematic review suggest that rehabilitation interventions for HNCaL, including standard lymphedema therapy with kinesio taping and APCDs, appear to be safe and beneficial. However, more prospective, controlled, and adequately powered studies are needed to clarify the ideal type, timing, duration, and intensity of lymphedema therapy components before treatment guidelines can be established.

Feasibility and Implementation of an Oncology Rehabilitation Triage Clinic: Assessing Rehabilitation, Exercise Need, and Triage Pathways within the Alberta Cancer Exercise-Neuro-Oncology Study. Curr Oncol 2023; 30:6220-6245. [PMID: 37504321 PMCID: PMC10377964 DOI: 10.3390/curroncol30070461] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 06/17/2023] [Accepted: 06/20/2023] [Indexed: 07/29/2023] Open
Abstract
Individuals living with and beyond cancer face physical impairment and inactivity in survivorship. Neuro-oncology populations have especially high rates of sedentary behaviour and functional deficits, including impaired balance, motor skills, and cognition. Our purpose was to assess the rehabilitation and exercise needs of patients with brain tumours while examining the feasibility of a rehabilitation triage clinic as a part of the Alberta Cancer Exercise-Neuro-Oncology study, where patients were referred to a triage clinic, where health, neurologic, and functional status was assessed, followed by a referral to one or multiple resources, including exercise, physiotherapy, occupational therapy, or physiatry. Qualitative perception of the triage clinic was collected. Overall, the triage clinic was feasible and safe for participants, facilitating referral into rehabilitation and exercise resources. Pre-determined enrollment and attendance rates were met, but referral rates to the triage clinic were not met. Oncology clinic staff reported forgetting to refer patients or uncertainty of who was appropriate for rehabilitation as barriers. Oncology clinic-based screening may improve the identification of patients who are sedentary or have a physical impairment. A proposed screening tool, the Cancer Rehabilitation and Exercise Screening Tool (CREST), is presented within our Cancer Rehabilitation and Exercise Pathways Model. The CREST can identify patients who are sedentary or have a functional impairment, facilitating referral to appropriate rehabilitation resources and ultimately improving patient recovery and functioning.

First-Year Implementation of the EXercise for Cancer to Enhance Living Well (EXCEL) Study: Building Networks to Support Rural and Remote Community Access to Exercise Oncology Resources. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:ijerph20031930. [PMID: 36767296 PMCID: PMC9915392 DOI: 10.3390/ijerph20031930] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 01/11/2023] [Accepted: 01/17/2023] [Indexed: 05/27/2023]
Abstract
Barriers to exercise-oncology programs remain for those living with and beyond cancer in rural and remote communities, including geographic isolation and access to programs. The EXercise for Cancer to Enhance Living Well (EXCEL) study was designed to support exercise-oncology implementation in rural and remote communities across Canada. The purpose of this analysis was to evaluate the first-year reach, adoption, and implementation of the EXCEL study. Reach outcomes included participant characteristics, study enrolment, and referral type (self vs. healthcare-provider [HCP] referral). Adoption outcomes included the number of clinical contacts, trained qualified exercise professionals (QEPs), and QEPs delivering EXCEL exercise classes. Implementation outcomes included retention, adherence, assessment completion rates, and adverse-event reporting. A total of 290 individuals living with cancer enrolled in EXCEL in year one, with an 81.4% retention to the study intervention. Most participants self-referred to EXCEL (75.8%). EXCEL's HCP network consisted of 163 clinical contacts, and the QEP network included 45 trained QEPs, 22 of whom delivered EXCEL classes. Adherence to the exercise intervention was 78.2%, and only one adverse event (mild) was reported. Fitness assessment and patient-reported outcome completion rates were above 85% pre- and post-intervention. EXCEL has developed HCP and QEP networks supporting exercise referral and online delivery, and the intervention is meeting feasibility markers. These implementation findings will inform the continued gathering of feedback across stakeholders to ensure that best evidence informs best practices.

Abstract
INTRODUCTION Individuals living with and beyond cancer from rural and remote areas lack accessibility to supportive cancer care resources compared with those in urban areas. Exercise is an evidence-based intervention that is a safe and effective supportive cancer care resource, improving physical fitness and function, well-being and quality of life. Thus, it is imperative that exercise oncology programs are accessible for all individuals living with cancer, regardless of geographical location. To improve accessibility to exercise oncology programs, we have designed the EXercise for Cancer to Enhance Living Well (EXCEL) study. METHODS AND ANALYSIS EXCEL is a hybrid effectiveness-implementation study. Exercise-based oncology knowledge from clinical exercise physiologists supports healthcare professionals and community-based qualified exercise professionals, facilitating exercise oncology education, referrals and programming. Recruitment began in September 2020 and will continue for 5 years with the goal to enroll ~1500 individuals from rural and remote areas. All tumour groups are eligible, and participants must be 18 years or older. Participants take part in a 12-week multimodal progressive exercise intervention currently being delivered online. The reach, effectiveness, adoption, implementation, and maintenance (RE-AIM) framework is used to determine the impact of EXCEL at participant and institutional levels. Physical activity, functional fitness and patient-reported outcomes are assessed at baseline and 12-week time points of the EXCEL exercise intervention. ETHICS AND DISSEMINATION The study was approved by the Health Research Ethics Board of Alberta. Our team will disseminate EXCEL information through quarterly newsletters to stakeholders, including participants, qualified exercise professionals, healthcare professionals and community networks. Ongoing outreach includes community presentations (eg, support groups, fitness companies) that provide study updates and exercise resources. Our team will publish manuscripts and present at conferences on EXCEL's ongoing implementation efforts across the 5-year study. TRIAL REGISTRATION NUMBER NCT04478851.

Abstract
Exercise is safe and effective for those living with and beyond breast cancer, with evidence supporting exercise guidelines, and position statements from international organizations. Despite the clearly recognized benefits of exercise for these individuals, many do not participate or maintain recommended exercise levels throughout the breast cancer continuum, highlighting the lack of translation from research into practice. In addition, discerning how exercise can be tailored to address breast cancer-related impairments, so that individuals are able to participate safely and effectively, has also not been studied extensively. Thus, we propose that implementing exercise screening, triage, and referral pathways across the breast cancer continuum may allow for increased accessibility and adoption among those living with and beyond breast cancer. This paper provides an overview of exercise prescription tailoring for common breast cancer and treatment-related impairments, proposes a simplified screening tool for identifying physical activity and movement-related impairments, and considers how best to channel evidence into practice via proposed implementation pathways that may better connect individuals living with and beyond breast cancer with exercise oncology resources through screening, triage, and referral.

Abstract
Physical activity is an important component of health and well-being, and is effective in the prevention, management, and treatment of numerous non-communicable chronic diseases. Despite the known health benefits of physical activity in all populations, most Canadians do not meet physical activity recommendations. Physicians play a key role in assessing, counselling, and prescribing physical activity. Unfortunately, many barriers, including the lack of adequate education and training, prevent physicians from promoting this essential health behaviour. To support Canadian medical schools in physical activity curriculum development, a team of researchers, physicians, and exercise physiologists collaborated to develop a key set of learning objectives deemed essential to physician education in physical activity counselling and prescription. This commentary will review the newly developed Canadian Physical Activity Counselling Learning Objectives and give case examples of three Canadian medical schools that have implemented these learning objectives.

Abstract
BACKGROUND Head and neck cancer (HNC) patients are an understudied population whose treatment often includes surgery, causing a wide range of side effects. Exercise prehabilitation is a promising tool to optimize patient outcomes and may confer additional benefits as a prehabilitation tool. The primary objective of this study was to assess the feasibility of measuring patient-reported outcomes (PROs), physical function, and in-hospital mobilization across the HNC surgical timeline in advance of a future prehabilitation trial. The secondary objective was to examine potential changes in these outcomes across the surgical timeline. METHODS HNC patients scheduled to undergo oncologic resection with free-flap reconstruction completed assessments of PROs and physical function at three timepoints across the surgical timeline (baseline, in-hospital, and postsurgical/outpatient). Mobilization was measured during the in-hospital period. The feasibility of recruitment and measurement completion was tracked, as were changes in both PROs and physical function. RESULTS Of 48 eligible patients, 16 enrolled (recruitment rate of 33%). The baseline and in-hospital PROs were completed by 88% of participants, while the outpatient assessments were completed by 81% of participants. The baseline and in-hospital assessment of physical function were completed by 56% of participants, and 38% completed the outpatient assessment. Measuring in-hospital mobilization was completed for 63% of participants. CONCLUSION Measuring PROs and in-hospital mobilization is feasible across the surgical timeline in HNC; however, the in-person assessment of physical function prior to surgery was not feasible. A multidisciplinary collaboration between exercise specialists and clinicians supported the development of new clinical workflows in HNC surgical care that will aid in the implementation of a future prehabilitation trial for this patient population.

Abstract
OBJECTIVES To provide health and fitness professionals with screening, triage, prescription, and physical activity recommendations to better serve individuals living with advanced cancer. A call to action regarding next steps to improve research and knowledge translation is also outlined, ensuring the growing number of those with advanced cancers are supported in their efforts to adopt and adhere to active lifestyles. DATA SOURCES Sources include published literature, physical activity guidelines, and expert opinion from physical medicine and rehabilitation physicians, exercise physiologists, and health and exercise psychology researchers. CONCLUSION Individuals with advanced cancer who engage in regular physical activity report improved function, fatigue management, and quality of life, while objective testing shows improvements in fitness and physical function. Although there are no clear activity guidelines or recommendations for this population, patients must avoid inactivity to gain health benefits and minimize deconditioning. For most patients with advanced cancer, physical activity prescriptions should focus on maintaining fitness and functional independence, and specific modifications based on common comorbidities must be considered. IMPLICATIONS FOR NURSING PRACTICE Evidence supports the use of physical activity for the management of symptoms experienced by those with advanced cancers. Understanding the benefits of physical activity for patients with advanced cancer is important because health care providers play a key role in the adoption and adherence of physical activity among patients.

Abstract
BACKGROUND Advanced lung cancer patients face significant physical and psychological burden leading to reduced physical function and quality of life. Separately, physical activity, nutrition, and palliative symptom management interventions have been shown to improve functioning in this population, however no study has combined all three in a multimodal intervention. Therefore, we assessed the feasibility of a multimodal physical activity, nutrition, and palliative symptom management intervention in advanced lung cancer. METHODS Participants received an individually tailored 12-week intervention featuring in-person group-based exercise classes, at-home physical activity prescription, behaviour change education, and nutrition and palliative care consultations. Patients reported symptom burden, energy, and fatigue before and after each class. At baseline and post-intervention, symptom burden, quality of life, fatigue, physical activity, dietary intake, and physical function were assessed. Post-intervention interviews examined participant perspectives. RESULTS The multimodal program was feasible, with 44% (10/23) recruitment, 75% (75/100) class attendance, 89% (8/9) nutrition and palliative consult attendance, and 85% (17/20) assessment completion. Of ten participants, 70% (7/10) completed the post-intervention follow-up. Participants perceived the intervention as feasible and valuable. Physical activity, symptom burden, and quality of life were maintained, while tiredness decreased significantly. Exercise classes prompted acute clinically meaningful reductions in fatigue, tiredness, depression, pain, and increases in energy and well-being. CONCLUSION A multimodal physical activity, nutrition, and palliative symptom management intervention is feasible and shows potential benefits on quality of life that warrant further investigation in a larger cohort trial.

Abstract
The health of Canadians depends on effective leadership among health care providers to facilitate the translation of new health discoveries into clinical practice. Clinician-scientists play an important role in bridging the gap between research and clinical practice, and require effective leadership skills to advance clinical practice successfully. To accelerate the leadership development in clinician scientist trainees, with the aim of developing strong leaders in administration and health advocacy, the Leaders in Medicine (LIM) training program at the University of Calgary created an Executive Leadership Coaching Program involving three phases: 1) an evidence-based evaluation tool, the Core Values IndexTM (CVI), that was used to identify the key drivers behind how individuals can be most effective in making their contribution; 2) small group workshops to debrief the results of the CVI assessment; and 3) one-on-one executive coaching sessions to facilitate the discovery, development and deployment of individual leadership capabilities. Coaching in leadership strategies enables clinician-scientist trainees to lead, influence, manage and deliver science-based improvements into the practice of medicine. We strongly recommend that other Canadian scientist-clinician training programs consider opportunities like the ones we offer to our LIM trainees. This training has important implications for the delivery of healthcare in Canada.

Abstract
Message from the President: Optimism for the Future The Clinician-Investigator Trainee Association of Canada (CITAC) was established in 2006 to address issues relevant to Canadian trainees seeking dual training in medicine and research. As clinician-investigator (CI) trainees, we comprise but a fraction (less than 5%) of all medical trainees. Our 'bilingual' careers render our individual paths less straightforward and more challenging. As a community, we have had to confront several disappointments, perhaps most notably the cessation of funding support for MD/PhD programs in 2015, previously offered by the Canadian Institutes of Health Research (CIHR). Despite these individual and collective challenges, I remain optimistic and incredibly excited about our future. In my own work, I am reminded constantly that being trusted with the dual responsibility of patient care and innovation in medicine is a privilege to be cherished, rather than a burden to be feared. That which makes our path doubly challenging also makes it doubly rewarding. The progress that CITAC has made over the years only adds to my optimism, and I wish to take this opportunity to remind you of how far we have come and how much further we hope to go.

Abstract
Recent guidelines concerning exercise for people with cancer provide evidence-based direction for exercise assessment and prescription for clinicians and their patients. Although the guidelines promote exercise integration into clinical care for people with cancer, they do not support strategies for bridging the guidelines with related resources or programs. Exercise program accessibility remains a challenge in implementing the guidelines, but that challenge might be mitigated with conceptual frameworks ("pathways") that connect patients with exercise-related resources. In the present paper, we describe a pathway model and related resources that were developed by an expert panel of practitioners and researchers in the field of exercise and rehabilitation in oncology and that support the transition from health care practitioner to exercise programs or services for people with cancer. The model acknowledges the nuanced distinctions between research and exercise programming, as well as physical activity promotion, that, depending on the available programming in the local community or region, might influence practitioner use. Furthermore, the pathway identifies and provides examples of processes for referral, screening, medical clearance, and programming for people after a cancer diagnosis. The pathway supports the implementation of exercise guidelines and should serve as a model of enhanced care delivery to increase the health and well-being of people with cancer.

Abstract
Objective Perforator flaps are one possible surgical treatment for burn scar contractures; however, a review of evidence on this topic is lacking. Methods MEDLINE was searched for articles related to perforator flaps for burn contractures. Following title and abstract screen, full texts were searched to identify articles describing perforator flaps for burn scar joint contractures. Data were extracted and summarized descriptively. Only articles that contained ≥10 patients with burn scar contracture were considered. Results Two hundred forty-eight articles were identified, of which 17 met criteria for review. Of these, 16 were low-quality case series, while 1 was an open randomized controlled trial. In total, perforator flaps were performed on 339 patients (age range: 3-75 years), with the most common contracture locations being cervical (n = 218) and knee (n = 41). Nine of the 17 articles described a rehabilitation strategy. In general, functional outcomes were excellent, with the majority of patients experiencing return of normal joint range of motion and no recontracture. Compared to full-thickness skin grafts, perforator flaps showed greater improvements in joint range of motion. Cosmetically, perforator flaps were shown to have good color match with surrounding tissue, good contour around anatomical landmarks, and improved overall patient appearance. The most common complications were marginal flap necrosis (n = 26 patients) and venous congestion (n = 17 patients). Conclusions Preliminary evidence from low-quality case series and 1 high-quality trial suggests perforator flaps may be successful for resurfacing released burn scar contractures; however, there is a need for additional trials comparing perforator flaps to other approaches.

Abstract
This study examined the exercise barriers and preferences of head and neck cancer (HNC) survivors in relation to exercise experience. Participants (n = 22; 46.8% response rate) completed retrospective self-report questionnaires on demographic and medical information, exercise barriers and preferences. A subset of participants then completed semi-structured interviews (n = 18). Participants had previously engaged in the ENHANCE trial during, or immediately following, radiation treatment, an average of 22.1 ± 5.8 months before. Retrospective questionnaires revealed that before ENHANCE participation, lack of interest and time were the primary exercise barriers. After participation, there was a significant decrease in typical barriers including lack of interest (p = .008), exercise not a priority (p = .039) and exercise not in routine (p = .004). Number of barriers experienced after ENHANCE participation was negatively correlated with age, quality of life and minutes of resistance exercise training per week. After ENHANCE participation, significant increases were found in preference for exercising at a cancer centre (p = .031) and with other cancer survivors (p = .016). Four higher order themes emerged inductively from interview data analysis pertaining to preferences (i.e., class format) and three higher order themes regarding barriers (physical, psychological and external). By investigating participants' perspectives after ENHANCE participation, key factors for effective HNC exercise programme design were identified.

[PMID: 26828426 DOI: 10.1002/cncr.29863] [Citation(s) in RCA: 74] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2015] [Revised: 11/13/2015] [Accepted: 11/30/2015] [Indexed: 12/13/2022]
Abstract
BACKGROUND Patients with head and neck cancer experience loss of weight and muscle mass, decreased functioning, malnutrition, depression, and declines in quality of life during and after treatment. The purpose of this exploratory randomized study was to determine the optimal timing for the initiation of a lifestyle and progressive resistance exercise training intervention (during or after radiation therapy), as determined by intervention adherence and by comparing between-group outcomes across 24 weeks. METHODS Sixty patients with head and neck cancer were randomized to engage in a 12-week lifestyle intervention and progressive resistance-training program either during radiation treatment or immediately after completion. The primary outcome of body composition--specifically, lean body mass, body mass index, and body fat--as well as secondary outcomes of fitness, quality of life, depression, and nutrition status were evaluated. RESULTS The progressive resistance-training intervention carried out during treatment did not significantly influence the primary outcome of body composition, despite a significant increase in weekly physical activity reported by the intervention group. A small-to-medium intervention effect was noted for some secondary outcomes, including fitness, quality of life, and nutrition status. Regardless of whether patients received the immediate or delayed progressive resistance-training intervention, the analysis revealed a main effect of time on body composition, fitness, quality of life, depression, and nutritional scores. CONCLUSIONS Although the intervention during treatment did not reduce the loss of lean body mass, delaying the exercise program until after treatment completion was associated with improved intervention adherence, a finding with important clinical implications.

Abstract
PURPOSE The purpose of the evaluation of this clinic-supported 12-week progressive strength-training program was to assess the feasibility and impact of an exercise intervention for head and neck cancer (HNC) survivors. METHODS Recruitment and adherence feasibility, as well as health-related fitness measures and patient-reported symptom management were assessed on the 21 HNC survivors in the exercise program. RESULTS Overall, this program was feasible, as indicated by recruitment, adherence, and safety outcomes. Survivors experienced improved acute symptom management over the period of one exercise class for tiredness, depression, anxiety, drowsiness, and overall wellbeing. Over the course of the program, survivors experienced significant improvements in physical functioning outcomes and improved management of tiredness and fatigue. CONCLUSIONS A progressive strength-training program is feasible for HNC survivors on and following treatment and is associated with improved acute and chronic fitness outcomes and symptom management.

Abstract
Empirical research suggests that yoga may positively influence the negative psychosocial and physical side effects associated with cancer and its treatment. The translation of these findings into sustainable, evidence-informed yoga programming for cancer survivors has lagged behind the research. This article provides (a) an overview of the yoga and cancer research, (b) a framework for successfully developing and delivering yoga to cancer populations, and (c) an example of a successful community-based program. The importance of continued research and knowledge translation efforts in the context of yoga and integrative oncology are highlighted.

Abstract
Background Research on physical activity and nutrition interventions aimed at positively impacting symptom management, treatment-related recovery and quality of life has largely excluded head and neck (HN) cancer populations. This translates into a lack of clinical programming available for these patient populations. HN cancer patients deal with severe weight loss, with more than 70% attributed to lean muscle wasting, leading to extended recovery times, decreased quality of life (QoL), and impaired physical functioning. To date, interventions to address body composition issues have focused solely on diet, despite findings that nutritional therapy alone is insufficient to mitigate changes. A combined physical activity and nutrition intervention, that also incorporates important educational components known to positively impact behaviour change, is warranted for this population. Our pilot work suggests that there is large patient demand and clinic support from the health care professionals for a comprehensive program. Methods/Design Therefore, the purpose of the present study is to examine the impact and timing of a 12-week PA and nutrition intervention (either during or following treatment) for HN cancer patients on body composition, recovery, serum inflammatory markers and quality of life. In addition, we will examine the impact of a 12-week maintenance program, delivered immediately following the intervention, on adherence, patient-reported outcomes (i.e., management of both physical and psychosocial treatment-related symptoms and side-effects), as well as return to work. Discussion This research will facilitate advancements in patient wellness, survivorship, and autonomy, and carve the path for a physical-activity and wellness-education model that can be implemented in other cancer centers.

Abstract
The purpose of the present investigation was to explore the effects of exercise and adrenaline on the mRNA expression of PGC-1alpha, a master regulator of mitochondrial biogenesis, in rat abdominal adipose tissue. We hypothesized that (1) exercise training would increase PGC-1alpha mRNA expression in association with increases in mitochondrial marker enzymes, (2) adrenaline would increase PGC-1alpha mRNA expression and (3) the effect of exercise on PGC-1alpha mRNA expression in white adipose tissue would be attenuated by a beta-blocker. Two hours of daily swim training for 4 weeks led to increases in mitochondrial marker proteins and PGC-1alpha mRNA expression in epididymal and retroperitoneal fat depots. Additionally, a single 2 h bout of exercise led to increases in PGC-1alpha mRNA expression immediately following exercise cessation. Adrenaline treatment of adipose tissue organ cultures led to dose-dependent increases in PGC-1alpha mRNA expression. A supra-physiological concentration of adrenaline increased PGC-1alpha mRNA expression in epididymal but not retroperitoneal adipose tissue. beta-Blockade attenuated the effects of an acute bout of exercise on PGC-1alpha mRNA expression in epididymal but not retroperitoneal fat pads. In summary, this is the first investigation to demonstrate that exercise training, an acute bout of exercise and adrenaline all increase PGC-1alpha mRNA expression in rat white adipose tissue. Furthermore it would appear that increases in circulating catecholamine levels may be one potential mechanism mediating exercise induced increases in PGC-1alpha mRNA expression in rat abdominal adipose tissue.

Abstract
Increasing evidence suggests that reduced adipose tissue mitochondrial content is associated with the pathogenesis of type 2 diabetes. These investigations have utilized severely insulin-resistant rodent models. Thus, it is difficult to ascertain the potential mechanisms that initiate these changes and whether reductions in adipose mitochondria are an initiating event in the development of impaired glucose homeostasis. Thus, we sought to determine the time course of high-fat diet-induced reductions of mitochondrial content in epididymal adipose tissue in relation to changes in purported mediators of mitochondrial biogenesis and the development of impaired glucose homeostasis. Male Wistar rats were fed a high-fat diet ( approximately 59% of kcals from fat) for 2, 4, or 6 wk. Six weeks of high-fat feeding resulted in reductions in CORE I, COX IV, cytochrome c, HSP60, relative mtDNA copy number, and PGC-1alpha expression. These changes were not associated with decreases in eNOS and AMPK or increases in markers of oxidative stress. Interestingly, ex vivo treatment of adipose tissue cultures with palmitate led to decreases in PGC-1alpha expression and COX IV and CORE I protein content as observed in vivo. Thus, the high-fat diet-induced reductions in adipose tissue mitochondrial proteins may be mediated by increases in plasma fatty acids. Importantly, reductions in adipose tissue mitochondrial content occurred after the development of impaired glucose homeostasis. Thus, reductions in adipose tissue mitochondrial proteins are most likely not a causal event in the development of impaired glucose homeostasis.
