RATIONALE: Regulatory focus (i.e., focus on motivation to achieve gains or avoid losses and non-gains) is used to tailor health behavior change interventions, improving efficacy, but is currently assessed by scales that are not health-specific and may capture a version of the construct that is not ideally matched to the rationale for tailoring. OBJECTIVE: We developed and validated a Health Regulatory Focus Scale (HRFS), which assesses tendencies to avoid negative health consequences (prevention focus) or achieve positive health outcomes (promotion focus)...

Exercise training can affect the breast tumor growth. We hypothesized that exercise training may reduce breast tumor growth by inducing Oxytocin (OT) secretion and its related signaling pathways such as PI3K/AKT and ERK. Therefore fifty-six BALB/c mice were equally divided into seven groups to study the effects of OT and atosiban (an oxytocin receptor antagonist) together with the interval exercise training on breast tumor growth, as well as tumor related signaling pathways including PI3K/AKT and ERK. Animal weight, OT plasma level, tumor weight and volume measured at the end of study...

Epigenetic modification refers to heritable changes in gene function that cannot be explained by alterations in the DNA sequence. The current literature clearly demonstrates that the epigenetic response is highly dynamic and influenced by different biological and environmental factors such as aging, nutrient availability and physical exercise. As such, it is well accepted that physical activity and exercise can modulate gene expression through epigenetic alternations although the type and duration of exercise eliciting specific epigenetic effects that can result in health benefits and prevent chronic diseases remains to be determined...

BACKGROUND: Using a secondary data analysis from randomized controlled trials comparing one year of resistance exercise (N=109) to a placebo control condition (N=106) in postmenopausal, post-treatment breast cancer survivors, we investigated the influence of resistance training and changes in body composition on markers associated with cancer progression. METHODS: Measures included serum levels of insulin, IGF-1, IGFBP1-3, leptin, serum amyloid A (SAA), adiponectin, C-reactive protein (CRP), IL-1β, TNF-α, IL-6, and IL-8 and body composition (total, lean and fat mass in kg) by DXA at baseline, 6, and 12-months...

The role of circulating microRNAs (c-miRNAs) in carcinogenesis has garnered considerable scientific interest. MiRNAs may contribute actively to cancer development and progression, making them potential targets for cancer prevention and therapy. Lifestyle factors such as physical activity (PA) have been shown to alter c-miRNAs expression but the subsequent impact on cancer risk and prognosis is unknown. To provide a better understanding of how PA reduces the risk of cancer incidence and improves patient outcomes, we conducted a review of the impact of PA on c-miRNAs expression, which includes a comprehensive synthesis of studies examining the impacts of acute and chronic exercise on expression of c-miRNAs...

Background: Cancer centers have increasingly offered integrative medicine therapies in response to their patients' unmet needs. We evaluated the growth of integrative medicine in leading academic cancer centers in the United States as reflected by their public-facing websites. Methods: We performed a systematic review of 45 National Cancer Institute (NCI)-designated comprehensive cancer center websites. Two researchers independently evaluated whether the websites provided information regarding integrative medicine modalities and, if so, whether the services were provided in the same health system...

PURPOSE: Exercise training is an effective and safe way to counteract cancer-related fatigue (CRF) and to improve health-related quality of life (HRQoL). High-intensity interval training has proven beneficial for the health of clinical populations. The aim of this randomized controlled trial was to compare the effects of resistance and high-intensity interval training (RT-HIIT), and moderate-intensity aerobic and high-intensity interval training (AT-HIIT) to usual care (UC) in women with breast cancer undergoing chemotherapy...

OBJECTIVES: To explore cancer patients' recommendations for nature engagement based on their subjective nature experiences and observations in the cancer setting. The rationale was to gain practical insight for delineating relevant and translatable nature-based care and design opportunities in oncology contexts. BACKGROUND: Innovative cancer care services are needed to respond to growing demand and shifting healthcare needs. Engagement with nature has shown multiple health benefits and presents a promising opportunity for application in healthcare to improve outcomes...

INTRODUCTION: Surgery is the standard curative treatment for lung cancer but is only possible in patients with local tumour and preserved exercise capacity. Improving fitness before surgery can reduce postoperative complications and mortality. However, preoperative rehabilitation remains difficult to implement for several reasons. We aim to investigate the effectiveness of an intensive 3-week home-based preoperative exercise training programme on hospital discharge ability, postoperative complications and physical performance in patients with chronic obstructive pulmonary disease (COPD) who are eligible for lung cancer surgery...

BACKGROUND: Cancer cachexia is characterized by muscle depletion and exercise intolerance caused by an imbalance between protein synthesis and degradation and by impaired myogenesis. Myofibre metabolic efficiency is crucial so as to assure optimal muscle function. Some drugs are able to reprogram cell metabolism and, in some cases, to enhance metabolic efficiency. Based on these premises, we chose to investigate the ability of the metabolic modulator trimetazidine (TMZ) to counteract skeletal muscle dysfunctions and wasting occurring in cancer cachexia...

BACKGROUND: Physical activity is an important outcome in oncology trials. Physical activity is commonly assessed using self-reported questionnaires, which are limited by recall and response biases. Recent advancements in wearable technology have provided oncologists with new opportunities to obtain real-time, objective physical activity data. The purpose of this review was to describe current uses of wearable activity monitors in oncology trials. METHODS: We searched Pubmed, Embase, and the Cochrane Central Register of Controlled Trials for oncology trials involving wearable activity monitors published between 2005 and 2016...

Movement is the basic attribute of life. It is not surprising that the return to regular physical activity is a very effective and cheap means of preventing and treating most non-cummunicable diseases. Therefore, every physician should be able to prescribe a suitable physical activity. The minimum amount of physical activity with proven effects in primary prevention of chronic diseases is relatively low: 150 minutes of moderate physical activity or 75 minutes of high intensity exercise per week or a combination of the two...

PURPOSE: To examine DNA methylation as a mechanism linking diet, physical activity, weight status, and breast cancer risk. METHODS: Insufficiently active women of varying weight status, without a history of cancer, completed a maximal exercise test, clinical measurement of height and weight, and a dietary intake measure. They also provided blood samples, which were analyzed to ascertain average methylation of candidate genes related to breast cancer (BRCA1, RUNX3, GALNT9, and PAX6) and inflammation (TLR4 and TLR6)...

PURPOSE: Ensuring and measuring adherence to prescribed exercise regimens are fundamental challenges in intervention studies to promote exercise in adults with cancer. This study reports exercise adherence in women who were asked to walk 150 min/week throughout chemotherapy treatment for early breast cancer. Participants were asked to wear a Fitbit(TM) throughout their waking hours, and Fitbit steps were uploaded directly into study computers. METHODS: Descriptive statistics are reported, and both unadjusted and multivariable linear regression models were used to assess associations between participant characteristics, breast cancer diagnosis, treatment, chemotherapy toxicities, and patient-reported symptoms with average Fitbit steps/week...

METHODS: Participants were randomized to a low-intensity, home-based program (Onco-Move), a moderate- to high-intensity, combined supervised resistance and aerobic exercise program (OnTrack), or Usual Care. Non-participants provided reasons for non-participation and were asked to complete a questionnaire assessing behavioral and attitudinal variables...
