Welcome to the podcast with Dr. Brendan McCarthy!   This episode takes you deep into the real-world practice of prescribing testosterone therapy for women. This is not a high-level overview—this is a nuts and bolts breakdown: ✅ Who it's for ✅ How it's dosed ✅ What labs to run ✅ What delivery methods are safest ✅ Why it's often done wrong—and how to get it right   With over 20 years of clinical experience, Dr. McCarthy shares the insights no seminar or textbook can offer, including the emotional and psychological challenges women face when beginning testosterone therapy, and the very real fears around side effects and community stigma.

Welcome to the podcast with Dr. Brendan McCarthy!   In this episode we dive deep into one of the most misunderstood and debated topics in hormone health: testosterone replacement therapy (TRT) for women. You may have heard horror stories—or glowing reviews. But what's the truth? Dr. McCarthy discusses: - Why testosterone matters for women's health - How it affects brain chemistry, mood, bone density, and even breast tissue - Its role after estrogen-suppressing breast cancer treatments - The difference between safe and unsafe TRT - What your provider should be doing to monitor and manage it effectively   Dr. Brendan McCarthy founded Protea Medical Center in 2002. While he's been the chief medical officer, Protea has grown and evolved into a dynamic medical center serving the Valley and Central Arizona. A nationally recognized as an expert in hormone replacement therapy, Dr McCarthy s the only instructor in the nation who teaches BioHRT on live patients. Physicians travel to Arizona to take his course and integrate it into their own practices. Besides hormone replacement therapy, Dr. McCarthy has spoken nationally and locally before physicians on topics such as weight loss, infertility, nutritional therapy and more.   Citations: Popma, Arne, et al.

What can the history of science tell us about the world we live in today and where we might be headed tomorrow? To find out, Dr. Charles Liu and co-host Allen Liu welcome historian of science Rebecca Charbonneau, PhD from the American Institute of Physics and the National Radio Astronomy Observatory with expertise in radio astronomy and the search for extraterrestrial intelligence (SETI). This episode kicks off with Allen and Chuck talking about January's Lunar Occultation of Mars. You can see a photo taken by Chuck on our YouTube Community tab. And then it's time for today's joyfully cool cosmic thing: a recent paper in the Astrophysical Journal Letters confirming there are galaxies that were fully formed just 400 million years after The Big Bang. Chuck, who studies galactic evolution, tells us why this changes our understanding of galaxy formation. Rebecca talks about how new ideas can be controversial and how personalities, politics and cultures can impact the evolution of science. She brings up the current controversy in astronomy concerning the locations of terrestrial telescopes and the tension between scientific and cultural imperatives. She also recounts seeing people in Russia wearing NASA t-shirts and explains how NASA understood the importance of controlling the narrative, even inviting Norman Rockwell to popularize the space program. Our first question comes from Pablo P. on Patreon, who asks, “Can humanity be destroyed by AI powered by quantum computing?” Rebecca explains how during the Cold War, scientists on both sides engaged in “science diplomacy” that helped lower tensions. She applies this thinking to AI, pointing out that while a “Terminator-like” scenario is unlikely, public concern is causing the tech world to confront and grapple with real threats from AI like biases in hiring algorithms. Allen, a mathematician who writes about AI professionally, addresses whether AI powered by quantum computing is more dangerous than AI in general. Rebecca shares the terrifying story of a Soviet nuclear submarine and the US navy during the Cuban Missile Crisis that nearly started a nuclear war. The dissenting actions of a single officer named Vasily Arkhipov made the difference, and she wonders if AI would have made the same decision based on the available data. For our next question, we return to our Pablo P. from Patreon for his follow up: “How [do] we answer the question about whether or not we are engaging in self-destructive behavior?” Chuck and Rebecca discuss the confluence of astronomy and the military, and how the history of the SETI program highlights their shared concerns. You'll find out what the Drake Equation has to do with concepts like The Great Filter. Science, she reminds us, is a tool to try to get closer to the truth, but it's not always perfect in pointing out whether what we're doing is safe or potentially self-destructive. Then we turn to Rebecca's other big passion, art history and the window into the human experience that art provides. Charles brings up The Scream by Edvard Munch and the fact that it's actually a depiction of a real atmospheric event. Rebecca talks the use of fractal studies to determine the authenticity of Jackson Pollock art. She also explores the artistic value of scientific artifacts like the controversial plaque attached to Pioneer 10 depicting a naked man and woman, and the interstellar Arecibo Message, sent by Frank Drake in 1974. You'll even hear how Frank worked himself into the message and what that has to do with Albrecht Durer's self-portrait painted in the year 1500. Finally, we turn to what Rebecca's been up to recently. Her new book Mixed Signals came out in January of this year.

The legendary ‪Charlie Morley‬ is talking about his IASD presentation in June 2025. In his keynote talk, Charlie will be discussing the remarkable results of two recent scientific studies that used lucid dreaming as a treatment for Post Traumatic Stress Disorder (PTSD). The results of the studies were quite remarkable, with the average PTSD score dropping so far below the medical threshold that dozens of participants were no longer classified as having PTSD by the end of the one-week study. He will also discuss the initial refusal to publish from many journals, the eventual publication in the peer-reviewed journal Traumatology, and his controversial TED talk on the subject that was blacklisted over disputed data. So, join us at this exciting talk to explore how lucid dreaming may well be one of the most promising interventions for trauma currently available.✨ Join Us at the IASD Conference! ✨The International Association for the Study of Dreams (IASD) is hosting its annual conference, bringing together some of the brightest minds in dream research, art, psychology, and spirituality.

In this captivating episode, we embark on a fascinating journey into the world of meditation and its potential as a treatment and preventive measure for Alzheimer's disease. While meditation is widely recognized for its ability to reduce stress, depression, and anxiety, it turns out there may be even more to this ancient practice.   Join us as we delve deeper into the remarkable imaging studies that prove structural changes in the brains of regular meditators. These changes not only contribute to enhanced cognitive behavior and memory but also serve as a protective mechanism against the onset of dementia.   However, the burning question remains: How significant is this data? By exploring the methodologies employed in these studies and understanding the implications of the results, we aim to shed light on the true potential of meditation in combating Alzheimer's.   Although we acknowledge that we are still in the early stages of research, it becomes clear that meditation is a wonderful intervention worth recommending.

We are joined again by Dr. Asher Brandt, Professor of Biochemistry at the Saint Joseph University, Connecticut, specializing in psychedelic pharmacology. We discuss a recently published paper about how Single Nucleotide Polymorphisms, (SNPs, pronounced “snips”) might alter the pharmacological signaling of potentially therapeutic psychedelics.SNPs are the most common type of genetic variation among people. Specifically, it's a genomic variant at a single base position in the DNA, which can lead to a single point amino acid mutation in the subsequently synthesized protein.In the study, the authors examined whether sequence variations in the 5-HT2A receptor gene affect the signaling of some of the most used psychedelic drugs such as LSD, mescalin, psilocybin. They examined the in vitro pharmacology of seven non-synonymous SNPs, which give rise to a variant of 5-HT2A serotonin receptors. What they found is that these non-synonymous SNPs exert statistically significant effects on not just the the efficacy but also the potency of four therapeutically relevant psychedelics.What's mind blowing, in our opinion, is that the in vitro pharmacological effects of the SNP drug actions at 5-HT2A receptor are both amino acid and drug specific.References:Schmitz et al.

我們以圍棋這項頂尖智力競技,作為人類認知功能隨年齡消長的模型分析,「一代不如一代」是錯誤的推論,這項研究成果剛獲《精神醫學與臨床神經科學》(Psychiatry and Clinical Neurosciences, IF=5.118)期刊接受。 圍棋是最困難的智力競技,規則長達百年而不變,而且有明確的勝負,很適合詮釋為人類認知功能在專業領域的表現,也可以公平地比較每個世代認知功能與專業表現的年齡軌跡。 我們分析從1980年以來的職業圍棋對局資料庫,其中62位曾獲世界冠軍棋士以及與他們曾經對局過的2,269位職業棋士,共94,189盤對局勝負的分析,觀察每個世代的圍棋世界冠軍在職涯歷程中棋力隨年齡的改變。 我們發現所有世代的職業棋士,代表認知功能的「全歷史等級分」隨著年齡大致呈倒U型的軌跡。每個世代中,較年輕的世代達到最巔峰的棋力,都超過上一個世代;而且達到巔峰棋力的年齡也比上一個世代更年輕。例如最年輕的Z世代棋士達到巔峰棋力的年齡約在20歲左右,而先前的X世代或Y世代棋士則是大約在25-30歲時方達到巔峰棋力,而最資深的戰後嬰兒潮世代則大約是在30歲之後才達到巔峰棋力。最年輕的Z世代棋士達到巔峰棋力的全歷史等級分超過3500,而Y世代的巔峰棋力則在3500左右,最資深的X世代與戰後嬰兒潮的巔峰棋力則低於3400。總結來說,在圍棋領域菁英的認知功能,是一代超越上一代,而且越年輕的世代達到認知功能巔峰的時間也比上一個世代更早、更年輕。 另一項高難度的智力競技,西洋棋世界冠軍的棋力年齡軌跡,與本研究中圍棋世界冠軍的結論也非常相似,由這兩個重要的人類認知功能模型可以推論「一代不如一代」是沒有任何實證根據的說法。

HIFT representa un método apropiado para mejorar el rendimiento cognitivo, específicamente la memoria de trabajo. Autor Jan Wilke Department of Sports Medicine, Goethe University Frankfurt am Main, Ginnheimer Landstraße 39, 60487, Frankfurt am Main, Germany. wilke@sport.uni-frankfurt.de. Enlace al Articulo Original en Ingles Los ejercicios aeróbicos y de resistencia (con pesas) aumentan de manera inmediata el rendimiento cognitivo (PC). El entrenamiento funcional de alta intensidad (HIFT) combina las características de ambos regímenes, pero su efecto sobre el rendimiento cognitivo no está claro. Treinta y cinco individuos sanos (26,7 ± 3,6 años, 18 mujeres) fueron asignados al azar a tres grupos. El primer grupo (HIFT) realizó un entrenamiento funcional con el máximo esfuerzo y en formato de circuito involucrando todos los grupos musculares del cuerpo, mientras que el segundo grupo (WALK) caminó al 60% de la reserva de frecuencia cardíaca. El tercer grupo permaneció físicamente inactivo leyendo un libro (CON). Antes y después del período de intervención que duro 15 minutos, el rendimiento cognitivo se evaluó con el Stroop Task, Trail Making Test y Digit Span Test. Se utilizaron ANOVA de medidas repetidas e intervalos de confianza del 95% post-hoc para detectar diferencias en los grupos y tiempo (previo y posterior a los protocolos). Se encontró una interacción significativa entre los grupos y el tiempo para la condición de conteo hacia atras de Digit Span Test (p = 0.04, IC 95%). HIFT fue superior a WALK y CON. Ademas, el análisis de la puntuación total del Digit Span Test y la condición incongruente del Stroop Task, reveló efectos pre y post (p 0.05). En conclusión, HIFT representa un método apropiado para mejorar de manera inmediata la memoria de trabajo, siendo potencialmente superior al ejercicio de tipo aeróbico moderado. El entrenamiento funcional de alta intensidad (HIFT, por sus siglas en inglés) como metodo de entrenamiento es una tendencia muy popular en el mundo del fitness, que integra el esfuerzo cardiovascular y muscular. El HIFT utiliza movimientos funcionales, multimodales y multiarticulares, por ejemplo, sentadillas, flexiones y burpees (Buckley et al., 2015). Los ejercicios funcionales utilizan todo el cuerpo y provocan un patrón de reclutamiento motor universal (Heinrich et al., 2014). El HIFT también tiene una configuración de intervalos de descanso mínimo o casi nulo (Feito, Heinrich, Butcher, & Poston, 2018). Las características mencionadas anteriormente confieren al HIFT la capacidad de mejorar la fuerza y la potencia muscular, así como de generar adaptaciones cardiovasculares anaeróbicas y aeróbicas, por lo que se ha demostrado que el HIFT desencadena efectos beneficiosos sobre el consumo de oxígeno (Vo2max), la potencia anaeróbica y fuerza muscular (Alcaraz et al., 2008; Brisebois et al., 2018; Menz et al., 2019). Además, el HIFT parece causar también beneficios neurofisiologicos. Los primeros estudios neurocientíficos asocian el HIFT con una reducción aguda del BDNF (García-Suárez et al., 2020), y curiosamente, en intervenciones más largas con un incremento del BDNF basal (Murawska-Ciałowicz et al., 2021). Además, una sesión aguda de entrenamiento del circuito HIFT mejoró la memoria a corto plazo y el control inhibitorio (Wilke et al., 2020) y una intervención de tres meses mejoró el rendimiento en el aprendizaje espacial, la separación de patrones y la capacidad de atención (Ben-Zeev, Hirsh, Weiss, Gornstein y Okun, 2020). En este estudio la intervencion consistía en una sesion de 15 ejercicios funcionales para todo el cuerpo, realizados en formato de circuito con repeticiones de 20 segundos de entrenamiento y 10 segundos de descanso. Con una duración total de 15 minutos. La selección de los ejercicios se basó en dos objetivos principales (a) la implicación de los principales grupos musculares para aumentar el consumo absoluto de oxígeno y (b) la simulación de patrones de movimiento fundamentales de uso diario (por ejemplo, sentadillas, desplantes, flexiones). El rendimiento cognitivo (CP), que puede subdividirse en funciones cognitivas de orden superior (por ejemplo, control inhibitorio o memoria de trabajo) y de orden inferior (por ejemplo, atención o tiempo de reacción). Las revisiones sistemáticas disponibles han investigado los efectos del ejercicio de tipo aeróbico, han detectando un efecto positivo en el CP incluso cuando se realiza como un único entrenamiento. Tanto el ejercicio continuo aerobico de intensidad moderada como de alta intensidad han reportado un impacto positivo en el rendimiento cognitivo. El test de Stroop consta de tres partes. En la primera y segunda sección de captación de la atención, se pide a los participantes que nombren lo más rápidamente posible las palabras escritas o los colores que aparecen en una hoja. La tercera sección representa una medida de control de la inhibición. Las palabras de colores se presentan de forma incongruente (por ejemplo, "verde" escrito en rojo o "azul escrito en amarillo"). Aquí, los participantes deben nombrar el color de la palabra mientras ignoraban las letras. Para el análisis posterior, se registra el tiempo necesario para completar la tarea. Se ha demostrado que el test de Stroop presenta una alta fiabilidad (ICC: 0,82) y consistencia interna (alfa de Cronbach: 0,93-0,97). Es el Episodio 4 Correr y Salud Mental puedes aprender mas sobre esta prueba cognitiva. El test de creación de rastros (TMT) consta de dos partes. En la parte A, los participantes deben conectar números linealmente crecientes utilizando un bolígrafo a la máxima velocidad posible. En la parte B, deben enlazar números y letras sucesivos (por ejemplo, del 1 al a y del 2 al b) de forma alterna. Al igual que en la prueba Stroop, se registra el tiempo necesario para completar la prueba. Los resultados de la prueba proporcionan una medida de detección visual/atención (TMT-A) y de flexibilidad cognitiva/memoria de trabajo (TMT-B). Se ha demostrado una alta fiabilidad (ICC: 0,81-0,86) y validez de constructo de la TMT. En la prueba de amplitud de dígitos, se realizan dos condiciones. En la primera, los participantes tienen que memorizar y repetir cantidades crecientes de números que se les leen. Al principio, deben recordar cuatro números. Si la memorización es satisfactoria, se les leen cinco números los memorizan y repiten, y asi continua subiendo la cantidad de numeros leidos que tienen que memorizar y repetir. Para cada paso, se realizan dos repeticiones y se otorgan uno o cero puntos en función del éxito de la memorización. La prueba termina si se fallan los dos ensayos. La segunda condición es idéntica a la primera, pero los números deben repetirse en orden inverso (por ejemplo, 2, 4, 7, 9 se convierte en 9, 7, 4, 2). Ambas partes de la prueba y la puntuación compuesta están relacionadas con la memoria a corto plazo y la memoria de trabajo. La prueba de amplitud de dígitos es fiable en las mediciones repetidas (r = 0,73). Los participantes del grupo WALK realizaron 15 minutos de marcha en cinta rodante al 60% de la reserva de frecuencia cardíaca individual. La RFC se determina mediante la fórmula de Karvonen (frecuencia cardíaca en reposo + ((frecuencia cardíaca máxima - frecuencia cardíaca en reposo) x intensidad). Esto es porque Los resultados de este estudio sugieren que el HIFT puede mejorar de forma inmediata el rendimiento cognitivo, concretamente la memoria a corto plazo/de trabajo y el control inhibitorio. Siendo el HIFT ligeramente superior al ejercicio aerobico continuo. Los autores mencionan que los posibles mecanismos que explican este aumento en el rendimiento cognitivo son Aumento de la perfusión cerebral tras el ejercicio de resistencia (Querido & Sheel, 2007; Ogoh & Ainslie, 2009). El aumento de los niveles séricos de cortisol y BDNF, que se ha reportado con entrenamiento de resistencia (pesas) (Tsai, et al. 2014; Yarrow, et al. 2010). Sin embargo los resultados son contradictorios en el sentido que no reportan mejoras con el ejercicio aeróbico, las cuales han sido encontradas en estudios anteriores con intensidades del 40 al 80% de la capacidad maxima de oxigeno ( Brisswalter, et al. 2002; Chang, et al. 2012). Acerca de este tema, Browne et al. 2017 sugiere que multiples factores, como el nivel de forma física y el modo de ejercicio, influyen en la relación entre el ejercicio y la cognición. Una implicación clinica práctica importante del presente estudio es que el HIFT representa una alternativa al uso de otros métodos de entrenamiento convencionales, no sólo en lo que respecta a la mejora o recuperacion de la función muscular y cardiovascular (Wilke, et al. 2020; Menz, et al. 2019), sino también cuando se pretende mejorar el rendimiento cognitivo a corto plazo. El HIFT también podría ser interesante para los individuos sedentarios con poca motivacion y tiempo limitado para hacer ejercicio, ya que se ha reportado una mayor motivacion intrinseca y mayor disfrute del ejercicio que una actividad de tipo aeróbico moderado (Wilke, et al. 2020). No se investigo la sosteníbilidad de la mejora de la PC, con evaluaciones de seguimiento adicionales, por lo que investigar los cambios 5, 10 15, 30, 60 minutos después o incluso 2, 6, 12, 24 horas después del entrenamiento a largo plazo es una tarea pendiente.No incluyó una comparación con una sesión de entrenamiento aeróbico o de resistencia con pesas de intensidad equivalente, es decir de alta intensidad. Solamente HIFT fue de alta intensidad, pero el ejercicio aeróbico estuvo en el limite superior de ejercicio de baja intensidad, con lo que la diferencia en intensidad pudo haber afectado la comparación.

Life From Plato's Cave

The prisoners in Plato's Cave live in a world of projections. They think they see a cat, but it is actually a shadow of a statue of a cat. Is it the same for us? Do we live in a kind of illusion? And if so, what are ways to see through this illusion and lift the fog at least a little? We explore these questions with neuroscientist, Buddhist and ballet dancer Marieke van Vugt.    About Marieke:  Marieke is an assistant professor in the cognitive modeling group at the University of Groningen (The Netherlands). She obtained her PhD with Michael Kahana in the neuroscience program of the University of Pennsylvania, after having spent one year at Brandeis University. After that I did a postdoc with Jonathan Cohen at Princeton University. The main question that guides her research is: how do we think? In what ways do we mind-wander? What effects does that have on decisions? And how can we make our thinking more adaptive by means of contemplative practices such as mindfulness and meditation. She likes to use mathematical models and techniques to better understand those very complicated data. This model-based neuroscience approach allows us to think about the mechanism by which someone thinks, and make more detailed predictions than verbal models.   Resources Marieke's website, twitter and ballet-related pictures on her instagram.  Mind and Life Institute: https://www.mindandlife-europe.org  Evan Thompson: research on whether meditation makes you a better scientist https://evanthompson.me/ Jostein Gaarder (1991).

Episode 29: In this episode, host Angie Gust talks about how we can calm our amygdalas. The amygdala is the part of our brain responsible for the experience of stress and can override the thinking part of our brains. If you'd like to try to calm your amygdala, you can try mindfulness meditation, breathing techniques, chanting, and listening to solfeggio frequencies. With regard to the environment, a new organization was recently formed called the Global Alliance for a Green New Deal and  includes lawmakers from every continent except Antarctica.  The goal of the group is to put the principles of a Green New Deal at the center of a global recovery from Covid-19. The group aims to put pressure on world governments ahead of the United Nations climate talks, COP 26, set to take place in Glasgow, Scotland, this November.

W dzisiejszym odcinku skupiam się na składnikach mineralnych, których niedobór może albo sprzyjać rozwojowi depresji, albo pogarszać przebieg leczenia. Jednakże, nie namawiam, by od razu rzucić wszystko i biec do apteki (i niekoniecznie w Bieszczady!) po suplementy, bo jak się okazuje więcej nie zawsze znaczy lepiej. Poza tym, to jedzenie jest pierwszym wyborem jeżeli chodzi o dostarczenie składników mineralnych do organizmu, suplementacja później.

Według różnych danych, zaburzeń depresyjnych doświadcza 1-1,5 mln Polaków. Według WHO, depresja dotyka ponad 264 mln osób na całym świecie. To są jednak dane z 2017 i początku 2020 roku, jeszcze przed wybuchem pandemii koronawirusa, która — nie oszukujmy się — wpłynęła na wszystkich negatywnie, głównie z powodu poczucia niepokoju, izolacji społecznej. Z kolei, według raportu ONZ dotyczącego związku COVID-19 ze zdrowiem psychicznym, pandemia może jeszcze pogorszyć te statystyki, które i tak nie były optymistyczne. Mamy problem ze zdrowiem psychicznym i tym bardziej zatrważa dostępność do specjalistów ds. zdrowia psychicznego - zgodnie z raportem ONZ, w skali świata, na każde 10 tys. osób przypada mniej niż 1 specjalista ds. zdrowia psychicznego. Co z tym można zrobić? Jedną z rzeczy, które mają wpływ na nasz nastrój i w tym na rozwój zaburzeń depresyjnych ma dieta. W tym odcinku skupiam się na związku diety z rozwojem zaburzeń depresyjnych. Nie skupię się jednak na przyczynach depresji czy innych zaburzeń nastroju, bo jest ich wiele, a ja nie mam takiej wiedzy żeby tutaj się mądrzyć z pozycji eksperta.

Wydawać by się mogło, że mózg jest jeden i to ten właśnie narząd odpowiedzialny jest za przetwarzanie informacji, samopoczucie czy zachowanie. Okazuje się, że co nieco — a może i nawet więcej niż co nieco — mają do powiedzenia jelita i mikrobiota jelitowa. Ich wpływ na mózg i cały organizm jest ważny do tego stopnia, że określa się je jako „drugi mózg”. Co to oznacza? W tym odcinku wyjaśnię, dlaczego jelita określane są drugim mózgiem, co do pracy "mózgów" mają bakterie, wirusy i grzyby, w jaki sposób nasze „mózgi” komunikują się ze sobą, a także jaki wpływ na zdrowie fizyczne i mentalne ma zaburzenie tej komunikacji.
