For the last podcast of 2022, I sit down with . Dr O’Mara is a Medical Doctor that is all about health optimisation, minimising the risk/reversing chronic disease. He is a clinician and researcher. His research has revolved around analysing the amount of visceral fat (fat around organs) using magnetic resonance imaging (MRI). Low visceral and pericardial fat is an important biomarker for health and longevity. He then implements lifestyle changes and conducts follow-up MRIs which show a reduction in visceral fat. We discuss a bevy of simple lifestyle choices that work best to keep visceral fat low and get you all living healthier and longer lives.

Dr O’Mara has provided medical care to former Presidents of the United States, Secretaries of State, and royalty. In 2004, he was recognised as the outstanding physician of the year among all medical specialties throughout the entire U.S. Army and was the first and only Emergency Medicine Physician to have received this award.

He works with individuals and corporations interested in the biological optimisation of humans through innovation and safe, natural lifestyle strategies shown to be more effective than medications. He especially enjoys working with exceptionally motivated individuals such as business executives, professional performers and athletes whose livelihood is predicated upon performance.

Episode 34: Evidence-Based Medicine - Are Doctors/Health professionals following the best evidence? To listen, click the link in my bio or listen on Spotify, Apple Podcasts

In this episode I sit down with Professor Rachelle Buchbinder and Professor Ian Harris. They have co-authored the book “Hippocrasy: How Doctors are Betraying their Oath”. Using the Hippocratic Oath as a framework they discuss themes such as doctors and health professionals using inadequate research to drive their practice, conflicts of interest in research, the need for more training on how to conduct and read research in medical school, medical errors, misdiagnosis, over-treatment, why old habits are hard to shift, whilst also offering solutions to these problems.

Prof. Rachelle Buchbinder is a physician specialising in rheumatology, Director of the Monash- Cabrini Department of Musculoskeletal Health and a Professor of Clinical Epidemiology at Monash University. She is known internationally as a vocal proponent of evidence-based medicine and for her landmark studies, particularly those examining treatments accepted into practice before proper evaluation. She has published more than 600 scientific papers and is in the top 0.1 per cent of the world’s most cited scientists. She was appointed an Officer of the Order of Australia (AO) for services to epidemiology and rheumatology in 2020.

Prof. Ian Harris is an orthopaedic surgeon at Liverpool, St George and Sutherland hospitals, Professor of Orthopaedic Surgery at UNSW Sydney and an Honorary Professor at the University of Sydney. Known internationally for his research and his support of evidence based practice, he has led many surgical trials and published approximately 300 scientific papers. His work has highlighted the lack of evidence for many of the treatments used in medicine, and surgery in particular, including his previous book, “Surgery, The Ultimate Placebo”, published in 2016. He was appointed a Member of the Order of Australia (AM) for services to orthopaedic surgery in 2015, and admitted as a fellow to the Australian Academy of Health and Medical Sciences in 2016.

The gut-brain connection in the mental health space appears well established. Given that the mouth is the start of the digestive tract it theoretically makes sense that the oral microbiome would too influence this. The gums contain a blood supply that can move inflammation-causing bacteria implicated in gum disease elsewhere in the body. Gum disease also sets up an inflammatory cascade that causes severe damage locally and systemically. The compartmentalising of the body is necessary to study disease in fine detail but needs to be applied acknowledging the interconnectedness of the body. No part of the body is an island.

This diagram is a schematic representation of this connection:
1) Periodontal bacteria can directly reach the brain via the bloodstream or areas that lack an intact Blood Brain Barrier (BBB) or with a compromised BBB. (2) Periodontitis can indirectly affect the CNS via pro-inflammatory cytokines that activate endothelial cells that express TNF-α and IL-1 receptors, which, in turn, signal to the perivascular macrophages that communicate and activate microglia, resulting in (3) neuroinflammation. (4) Periodontitis can also result in leaky periodontium and LPS in systemic circulation, which can (5) activate the HPA axis and result in increased stress hormones or neurotransmitters, which subsequently (6) influence gut physiology, microbiota habitat, microbiota community composition, and bacterial gene expression. (7) An altered gut microbiota can result in systemic inflammation, which not only affects the CNS but also (8) exacerbates other inflammatory pathologies, such as periodontitis. Periodontal bacteria can directly influence gut microbial community composition and functioning via (9) enteral transmission or indirectly via (10) hematogenous transmission (which is facilitated by conditions such as gastritis, gastric surgery, or gastric dysfunction). CNS, central nervous system; TNF, tumor necrosis factor; IL-1, interleukin-1; LPS, lipopolysaccharide; BBB, blood–brain barrier; HPA, hypothalamic–pituitary–adrenal. Solid arrows indicate direct pathways and dotted arrows indicate indirect pathways.

The dentition tells a story. The mouth provides clues about what else may be happening to an individual’s health. The integrity/quality of the teeth are influenced by the environment in which they are formed. The first stage begins in the foetus at about 6 weeks and the hard tissue that surrounds the teeth is formed around 3 to 4 months of gestation. This is not widely understood by the public.
