Evaluating Wall-Mounted Prompts to Facilitate Physical Activity-Related Discussion between Individuals with Cancer and Oncology Health Care Providers: A Pre-post Survey Study.

Purpose: To evaluate the use of wall-mounted prompts in facilitating physical activity (PA)-related discussions between individuals with cancer and oncology care providers. Methods: Individuals with cancer were approached to participate in a survey-based pre-post study. Half of participants (n = 100) completed a survey prior to installation of wall-mounted prompts in clinic while the other half (n = 100) completed a survey following installation of the prompts. Survey questions included content of PA-related discussion, satisfaction with PA education across treatment, and current PA level. The post-prompt survey also asked questions related to the prompt. Survey responses were analyzed using descriptive statistics. Chi-squared tests were performed to determine significance between timepoints. Results: One hundred participants completed the survey at each timepoint. A significant difference was found pre and post-prompt in the number of PA discussions occurring overall during care (p = 0.03). Some participants (53%) were satisfied with the PA education received during treatment. There was no significant difference in occurrence of PA discussion (p = 0.36) pre and post-prompt and no difference in PA behaviour was observed (p = 0.130). Conclusions: Wall-mounted prompts may be effective in increasing the frequency of PA-related discussions between individuals with cancer and their oncology team across treatment. Additional strategies, such as easy referral to rehabilitation professionals, are also needed to facilitate safe and effective PA behaviour during and after cancer treatments.

Objectif: évaluer l'utilisation des messages muraux pour faciliter les discussions sur l'activité physique (AP) entre les personnes atteintes d'un cancer et les professionnels de la santé en oncologie. Méthodologie: des personnes cancéreuses ont été invitées à participer à une étude avant-après par sondage. La moitié (n = 100) a rempli un sondage avant l'installation de messages muraux en clinique, tandis que l'autre moitié (n = 100) l'a rempli après l'installation de ces messages. Les questions du sondage incluaient le contenu des discussions liées à l'AP, la satisfaction envers l'éducation à l'AP tout au long du traitement et le taux d'AP actuelle. Le sondage avant-après comportait aussi des questions au sujet des messages. Les chercheurs ont analysé les réponses au sondage au moyen de statistiques descriptives et ont procédé à des tests du chi carré pour déterminer le caractère significatif entre chaque sondage. Résultats: au total, 100 participants ont rempli chacun des sondages. Les chercheurs ont observé une différence significative avant et après les messages quant au nombre de discussions globales sur l'AP pendant les soins (p = 0,03). Certains participants (53 %) étaient satisfaits de l'éducation sur l'AP donnée pendant le traitement. Il n'y avait pas de différence significative quant à l'occurrence de discussions sur l'AP (p = 0,36) avant et après le message ni quant aux comportements relatifs à l'AP (p = 0,130). Conclusions: les messages muraux peuvent contribuer à accroître la fréquence des discussions sur l'AP entre les personnes atteintes du cancer et leur équipe d'oncologie tout au long du traitement. D'autres stratégies, comme une orientation facile vers des professionnels de la réadaptation, s'imposent également pour favoriser un comportement sécuritaire et efficace à l'égard de l'AP pendant et après les traitements en oncologie.

Repurposing Two Old Friends to Fight Cancer: Caffeine and Statins.

Statins are a class of cholesterol-lowering drugs that inhibit 3-hydroxy-3-methylglutaryl-CoA reductase, the rate-limiting enzyme of the mevalonate pathway. Evidence suggests that certain cancers depend on the mevalonate pathway for growth and survival, and thus blocking the mevalonate pathway with statins may offer a viable therapeutic approach for treating cancer, or at least enhance the efficacy of existing cancer drugs. In this issue of Cancer Research, Tran and colleagues showed that caffeine works jointly with FOXM1 inhibition to enhance the antitumor activity of statins in neuroblastoma cells. They found that caffeine synergizes with statins by suppressing statin-induced feedback activation of the mevalonate pathway. Here, we reflect on the potential of combining caffeine and statin drugs as a strategy for potentiating anticancer activity. See related article by Tran et al., p. 2248.

Regulation of Skeletal Muscle Plasticity by Protein Arginine Methyltransferases and Their Potential Roles in Neuromuscular Disorders.

Protein arginine methyltransferases (PRMTs) are a family of enzymes that catalyze the methylation of arginine residues on target proteins, thereby mediating a diverse set of intracellular functions that are indispensable for survival. Indeed, full-body knockouts of specific PRMTs are lethal and PRMT dysregulation has been implicated in the most prevalent chronic disorders, such as cancers and cardiovascular disease (CVD). PRMTs are now emerging as important mediators of skeletal muscle phenotype and plasticity. Since their first description in muscle in 2002, a number of studies employing wide varieties of experimental models support the hypothesis that PRMTs regulate multiple aspects of skeletal muscle biology, including development and regeneration, glucose metabolism, as well as oxidative metabolism. Furthermore, investigations in non-muscle cell types strongly suggest that proteins, such as peroxisome proliferator-activated receptor-γ coactivator-1α, E2F transcription factor 1, receptor interacting protein 140, and the tumor suppressor protein p53, are putative downstream targets of PRMTs that regulate muscle phenotype determination and remodeling. Recent studies demonstrating that PRMT function is dysregulated in Duchenne muscular dystrophy (DMD), spinal muscular atrophy (SMA), and amyotrophic lateral sclerosis (ALS) suggests that altering PRMT expression and/or activity may have therapeutic value for neuromuscular disorders (NMDs). This review summarizes our understanding of PRMT biology in skeletal muscle, and identifies uncharted areas that warrant further investigation in this rapidly expanding field of research.
