From consensus to action: Knowledge transfer, education and influencing policy on sports concussion
ABSTRACT Objective To: (1) provide a review of knowledge transfer (KT) and related concepts; (2) look at the impact of traditional and emerging KT strategies on concussion knowledge and education; (3) discuss the value and impact of KT to organisations and concussion-related decision making and (4) make recommendations for the future of concussion education. Design Qualitative literature review of KT and concussion education literature. Intervention PubMed, Medline and Sport Discus databases were reviewed and an internet search was conducted. The literature search was restricted to articles published in the English language, but not restricted to any particular years. Altogether, 67 journal articles, 21 websites, 1 book and 1 report were reviewed. Results The value of KT as part of concussion education is increasingly becoming recognised. Target audiences benefit from specific learning strategies. Concussion tools exist, but their effectiveness and impact require further evaluation. The media is valuable in drawing attention to concussion, but efforts need to ensure that the public is aware of the right information. Social media as a concussion education tool is becoming more prominent. Implementation of KT models is one approach which organisations can use to assess knowledge gaps; identify, develop and evaluate education strategies and use the outcomes to facilitate decision-making. Conclusions Implementing KT strategies requires a defined plan. Identifying the needs, learning styles and preferred learning strategies of target audiences, coupled with evaluation, should be a piece of the overall concussion education puzzle to have an impact on enhancing knowledge and awareness

Aerobic training affects fatty acid composition of erythrocyte membranes
Abstract The effect of exercise training on the fatty acid composition of erythrocyte membranes was evaluated in an experimental animal model where rats were subjected to a ten-wk aerobic training. Five groups of rats were compared: sedentary rats at 19 or 23 wks of age, rats trained at moderate or high intensity sacrificed at 19 wks of age, and rats trained at high intensity, and sacrificed following 4 weeks of sedentary life. We had already demonstrated that cardioprotection correlates with training intensity and partially persists in detrained rats. Main findings are that rats trained at higher intensity display consistent signs of lipid peroxidation but a lower ω6/ω3 ratio and a lower content of trans fatty acids when compared to rats trained at lower intensity and to older sedentary rats. Trans fatty acids negatively affect cell membrane fluidity and permeability. Detrained rats showed intermediate values. Gene expression evaluation of selected enzymes involved in lipid biosynthesis revealed some of the adaptive mechanisms leading to the maintenance of membrane fatty acid homeostasis following exercise. The decrease in the amount of trans fatty and in the inflammatory pathways (i.e. ω6/ω3 ratio) in high-intensity trained rats underscores the protective effect of high intensity aerobic training.</p
The Equitable Benefit Approach to guide the assessment of medical and psychosocial factors in liver transplant candidacy
:Lack of available organs poses a significant challenge in meeting the needs of patients with life-threatening liver disease who could benefit from liver transplantation (LT). Psychosocial vulnerability markers have been linked to post-transplant outcomes, raising questions about their use in patient selection. However, their incorporation into selection criteria raises concerns about health equity and potential discrimination. As a result, there is a pressing need to refine fair allocation systems that consider both clinical and psychosocial factors to ensure equitable access and optimize post-transplant outcomes. The Equitable Benefit Approach (EBA) proposed in this paper by the multidisciplinary group of clinical experts in LT from the Italian Society for the Study of the Liver seeks to address these concerns. It presents four procedural principles, the two allocative principles usually applied in transplantation (urgency and utility) and introduces a new one, the principle of health equity. The EBA aims to prioritize patients with the highest transplant benefit while addressing health inequalities. It emphasizes evidence-based decision-making and standardized assessment tools to reliably evaluate psychosocial risk factors. Implementing the EBA involves a multi-step process, including stakeholder engagement, prospective studies to validate its efficacy, development of institutional policies and algorithms, and ongoing monitoring and revision. By following these steps, health care providers can ensure that LT allocation decisions are transparent and responsive to evolving clinical and social contexts. Ultimately, the EBA should offer a comprehensive framework for fair patient selection in LT, considering both biomedical and psychosocial aspects
Endogenous Opioids and Their Role in Stem Cell Biology and Tissue Rescue
Opioids are considered the oldest drugs known by humans and have been used for sedation and pain relief for several centuries. Nowadays, endogenous opioid peptides are divided into four families: enkephalins, dynorphins, endorphins, and nociceptin/orphanin FQ. They exert their action through the opioid receptors (ORs), transmembrane proteins belonging to the super-family of G-protein-coupled receptors, and are expressed throughout the body; the receptors are the δ opioid receptor (DOR), μ opioid receptor (MOR), κ opioid receptor (KOR), and nociceptin/orphanin FQ receptor (NOP). Endogenous opioids are mainly studied in the central nervous system (CNS), but their role has been investigated in other organs, both in physiological and in pathological conditions. Here, we revise their role in stem cell (SC) biology, since these cells are a subject of great scientific interest due to their peculiar features and their involvement in cell-based therapies in regenerative medicine. In particular, we focus on endogenous opioids’ ability to modulate SC proliferation, stress response (to oxidative stress, starvation, or damage following ischemia–reperfusion), and differentiation towards different lineages, such as neurogenesis, vasculogenesis, and cardiogenesis
Herb-Derived Products: Natural Tools to Delay and Counteract Stem Cell Senescence
Cellular senescence plays a very important role in organismal aging increasing with age and in age-related diseases (ARDs). This process involves physiological, structural, biochemical, and molecular changes of cells, leading to a characteristic trait referred to \u201csenescence-associated secretory phenotype (SASP).\u201d In particular, with aging, stem cells (SCs) in situ exhibit a diminished capacity of self-renewal and show a decline in their functionality. The identification of interventions able to prevent the accumulation of senescent SCs in the organism or to pretreat cultured multipotent mesenchymal stromal cells (MSCs) prior to employing them for cell therapy is a main purpose of medical research. Many approaches have been investigated and resulted effective to prevent or counteract SC senescence in humans, as well as other animal models. In this work, we have reviewed the chance of using a number of herb-derived products as novel tools in the treatment of cell senescence, highlighting the efficacy of these agents, often still far from being clearly understood
