    How bone hormones shape our health and longevity with Prof Gerard Karsently

    Bone is not just a passive scaffold that supports our body. It is also an active endocrine organ that secretes hormones that regulate various aspects of our physiology, from energy metabolism to brain function. One of these hormones is osteocalcin, which has been extensively studied by Gerard Karsently and his team at Columbia University. In this podcast, we will explore the fascinating discoveries that Karsently and his colleagues have made about osteocalcin and its role in health and disease. Osteocalcin is a protein that is produced by bone cells called osteoblasts. It is then released into the bloodstream, where it can reach different organs and tissues and exert its effects. Osteocalcin has been shown to enhance insulin secretion by the pancreas, testosterone production by the testes, muscle function during exercise, memory formation and mood regulation by the brain, and even the ability to cope with stress. Osteocalcin also has anti-aging properties, as it can prevent or reverse some of the decline in physiological functions that occurs with age. The levels of osteocalcin in the blood are not constant. They vary depending on several factors, such as diet, exercise, stress and age. These interactions create a complex network of communication between bone and other organs that helps to maintain homeostasis and adapt to changing conditions. Karsently's research has opened new avenues for understanding the biology of bone and its impact on whole-body physiology. It has also revealed new potential therapeutic targets or strategies for treating or preventing various metabolic, reproductive, cognitive and emotional disorders. In this podcast, we will dive deeper into the fascinating world of osteocalcin and bone endocrinology with Gerard Karsently himself. Useful Links: Berger JM, Karsenty G.

    The Sunny Side of Health: How Sun Exposure Can Prevent Chronic Diseases with Prof Prue Hart

    The information in this podcast is intended for Healthcare Practitioners. Sun exposure has been valued for its healing properties throughout history and across cultures. But too much of a good thing can be harmful, and in recent decades we have been warned about the risks of sunburn, skin ageing and skin cancer. However, our guest expert today argues that we may have gone too far in avoiding the sun, and that we are missing out on its vital benefits for our health and well-being. Prof Prue Hart is a photoimmunologist who has been studying the effects of vitamin D and ultraviolet radiation (UVR) on health and disease for over 20 years. She has found evidence that insufficient sun exposure is linked to increased mortality and various chronic conditions, such as some cancers, cardiovascular disease and neurological disorders. Moreover, she has discovered that these benefits are not only due to vitamin D production, but also to other molecules that are activated by UVR, such as nitric oxide and urocanic acid. In this podcast, Prof Hart will explain how these molecules work in our body, and how they can help us prevent or treat diseases such as COVID-19 and multiple sclerosis. She will also share some practical tips on how to balance sun exposure and protect our skin health. Join us for this enlightening conversation on the sunny side of health.

    Thriving in menopause: Insights from a leading researcher and advocator Prof Mary Ann Lumsden

    *The information in this podcast is intended for Healthcare Practitioners. Despite women spending more of their lives in a post-menopausal state, there has been limited progress in how society views and supports menopausal women. In this episode, we are joined by Professor Mary Anne Lumsden, a leading researcher and menopause advocate, to examine menopause from all angles. Professor Lumsden explains that with appropriate biopsychosocial support, menopausal women can thrive and be revered. The conversation begins by exploring the evolutionary theory of the grandma hypothesis, which suggests that menopause is a feature rather than a bug. We delve into the menopausal transition and how symptoms, such as hot flushes, are not solely driven by an absolute estrogen deficiency. In this light, non-hormonal treatments are explored. Additionally, Professor Lumsden outlines the latest updates on the benefits and risks of menopausal hormone replacement therapy, suggesting that the risks may have been overstated in the past. We then turn to the health challenges that menopausal women often face, such as unwanted weight gain, body composition changes, osteoporosis, and dementia. Professor Lumsden provides insights on evidence-based clinical strategies to support women during this transitional phase of life. Tune in for a menopausal masterclass that offers an evolutionary, biopsychosocial, and clinical perspective on how menopausal women can thrive. Mary Ann Lumsden is the CEO of the International Federation of Gynecology and Obstetrics and former Professor of Medical Education & Gynaecology and Head of Reproductive & Maternal Medicine, University of Glasgow. She is Past Senior Vice President for Strategy at the Royal College of Obstetricians and Gynaecologists in London. Mary Ann has considerable experience of developing Guidelines. She was Chair of the Guidelines Development Group for the National Institute of Health and Care Excellence (NICE) Guideline ‘Menopause: Investigation and Management’. Her success in this field was recognised in 2017 when she was awarded an OBE (Officer of the Order of the British Empire) for Services to Women’s Health. Links Lumsden MA, Sassarini J.

    Alzheimer’s Disease: From Despair to Hope with Prof Ralph Martins

    *The information in this podcast is intended for Healthcare Practitioners. Alzheimer’s disease is a devasting illness that robs patients of quality and quantity of life and is the leading cause of death in women. Alzheimer’s is also the most feared condition in middle to older age adults. This may be in part due to fact, to date, there is little to no evidence that pharmaceutical intervention can slow, let alone reverse, the condition once established. Despite the current pessimistic outlook, there is a growing body of evidence that Alzheimer’s can be prevented, slowed, and potentially reversed. Joining the podcast is a juggernaut in Alzheimer’s research, Prof Ralph Martins. For over three decades Prof Martins has explored Alzheimer’s from all angles – and the future looks promising. In this episode Prof Martins discusses the central role of beta amyloid in Alzheimer’s, whilst touching upon some concerns of its clinical utility. Further, Prof Martins reveals some emerging biomarkers that may be a game changer in the near future. Prof Martin then describes powerful, yet not widely appreciated risk factors, namely hearing loss and poor sleep. The conversation also explores the role of APOE in Alzheimer’s and findings from his research on dietary factors linked to neuroprotection. Despite the size of the problem, the details in the podcast and Prof Martins' energy and passion should leave listeners with confidence positive change is on the horizon. Professor Ralph Martins is the Foundation Chair in Aging and Alzheimer’s Disease at Edith Cowan University. His collaborative seminal research involved isolating and characterising beta-amyloid and its precursor, the amyloid precursor protein (APP), which are now recognised as central to the pathogenesis of Alzheimer's disease. He was the first to propose and demonstrate that the Alzheimer brain was under oxidative stress, which is now widely recognized by the Alzheimer research community. Ralph's current research interests are focused on understanding the mechanisms and factor(s) leading to the abnormal release and deposition of βA4 in Alzheimer's disease.

    When Brains Dream with Prof Bob Stickgold

    *The information in this podcast is intended for Healthcare Practitioners. Dreams have been a source of fascination across seemingly all cultures over the history of humankind. Likewise, there has been numerous suggestions throughout the ages on the purpose of dreams and the interpretation of dreams. Over the past three decades, sleep and dream researcher Prof Bob Stickgold has developed an ingenious model of the purpose and benefits of dreaming. To understand dreaming, we first need to understand sleep. In this episode, Prof Stickgold describes how sleep is vital for memory evolution – a process not simply to consolidate information of the past with perfect fidelity, but to help guide us better in the future. From here, we explore how dreaming helps reinforce memory evolution, above and beyond sleeping. Finally, the conversation explores how disturbed sleep and dreaming plays a role in the persistence of post-traumatic stress disorder (PTSD) and how this may be addressed.
