    Jeanne Marrazzo, MD: NIH-NIAID Lawsuit

    When a globally respected infectious disease expert is abruptly sidelined by an anti‑vaccine administration, what does it reveal about the future of public health and scientific integrity?   In this episode, Therese Markow and Dr. Jeanne Marrazzo discuss her termination and whistleblower lawsuit against the U.S. government. She highlighted NIAID's critical role in infectious disease research, funding $6.6 billion annually. Dr. Marrazzo criticized the new administration's anti-vaccine stance, cessation of global HIV/AIDS funding, and termination of clinical trials, which she argued endangered public health. Dr. Marrazzo filed a whistleblower complaint in September 2025, leading to her firing in October. She now leads the Infectious Disease Society of America, advocating for evidence-based policies and scientific integrity.    Key Takeaways: Tuberculosis (TB, formerly known as Consumption) is now the top global killer as an infectious disease. Shutting down clinical trials and cutting international research funding mid‑stream doesn't just waste taxpayer dollars; it endangers patients who rely on those therapies and violates core ethical standards. Political ideology overriding scientific evidence can rapidly dismantle decades of progress in vaccines, global health research, and public trust. Independent professional societies and medical organizations now play a critical role in evidence above ideology, preserving rigorous guidelines, publishing unbiased research, and speaking truth to power when government agencies are silenced or hollowed out.   "What I don't think people realize is the power of the platform that the Secretary and indeed the President have. The tragic part about this is that we've spent decades building up that trust, trying to make sure that it was justified, and to see that just summarily destroyed, there's no other word for it, is really, really tragic. I don't know what it's going to take to build it up again." —  Jeanne Marrazzo, MD   Connect with Jeanne: Professional Bio:  https://www.niaid.nih.gov/about/jeanne-marrazzo-md-mph  Website: https://www.idsociety.org/  LinkedIn: https://www.linkedin.com/in/jeanne-marrazzo-203463179    Connect with Therese: Website:  www.criticallyspeaking.net Bluesky: @CriticallySpeaking.bsky.social Instagram: @criticallyspeakingpodcast Email: theresemarkow@criticallyspeaking.net   Audio production by Turnkey Podcast Productions.

    Dr. Chelsea Polis: Women's Reproductive Rights on the Move

    In this episode, Therese Markow and Dr. Chelsea Polis discuss the evolution of reproductive rights in the U.S., highlighting the 2022 Supreme Court decision revoking the right to abortion and the historical context of contraception access. Dr. Polis also explains fertility awareness-based methods (FABMs) and their effectiveness, noting that some methods have moderate quality studies suggesting high effectiveness, while others are less reliable. She emphasizes the importance of evidence-based information, the need for stronger regulation of femtech products, and the potential privacy risks associated with reproductive health data. Dr. Polis also addresses the broader political strategy to limit reproductive rights and the importance of reproductive justice.    Key Takeaways: Fertility tracking technologies are becoming more common (often called femtech), but it is important to note that only two apps have currently been cleared by the FDA for contraceptive purposes - Natural Cycles and Clue (the second is not currently available on the market). While others can help with tracking your cycle, they are not cleared for contraceptive use. FABMs focus on observing real-time signs from the body - such as cervical mucus changes and basal body temperature. Over a dozen have been studied in clinical trials, but some methods have been marketed or promoted for contraceptive use without strong evidence from appropriately designed effectiveness studies. For people who are in a partnership that is limited in terms of communication, or not supportive, or certainly abusive, or anything along those lines, FABMs would not be a method that somebody could rely on for pregnancy prevention.  Be very cautious about getting your information on contraception from social media influencers or companies selling specific products, because there is a lot of misinformation out there.   "As my colleagues at Guttmacher have documented, you can't seek to restrict one aspect of sexual and reproductive health without tightening other types of care and people's overarching reproductive freedoms. All of these things are deeply interconnected." —  Dr. Chelsea Polis   Episode References:  Guttmacher: https://www.guttmacher.org/united-states/contraception  Emergence of FemTech in the Sexual and Reproductive Health Landscape: https://www.contraceptionjournal.org/content/femtech    Connect with Dr. Chelsea Polis: Professional Bio: https://www.guttmacher.org/about/staff/chelsea-polis  Website: https://www.chelseapolis.com/index.html  LinkedIn: linkedin.com/in/chelseapolis  Bluesky: https://bsky.app/profile/cbpolis.bsky.social    Connect with Therese: Website:  www.criticallyspeaking.net Bluesky: @CriticallySpeaking.bsky.social Instagram: @criticallyspeakingpodcast Email: theresemarkow@criticallyspeaking.net   Audio production by Turnkey Podcast Productions.

    Osteoporosis and You

    In this episode, Therese Markow and Dr. Keith McCormick discuss what you need to know about osteoporosis and bone health. Dr. McCormick explains what causes osteoporosis, the importance of early bone density tests, and breaks down some of the lifestyle factors that affect bone health. They discuss the need for personalized treatment beyond only medication, and Dr. McCormick advocates for patient empowerment and comprehensive understanding to improve treatment outcomes.     Key Takeaways: 50% of women will get osteoporosis. 20% of men will get osteoporosis.  People should be getting bone density tests in their forties, not waiting until their fifties or sixties. The sooner it is discovered you are having symptoms, the sooner you can begin to treat and prevent.  Bone strength is a combination of bone density and bone quality. Get both the DEXA and Trabecular Bone Score or TBS. Usually, physicians don't request the TBS, but it is very important.  Ask for it. Testing should include blood tests for bone turnover markers. Your blood is telling a larger story, and it can get complicated.  Systemic inflammation can also be tested, as it can contribute to loss of bone density. The more times you stimulate your body, the more you will stimulate the osteoblasts.    "It's important to understand that you, the patient, are the boss, and you're paying that person, you're asking that person for help, and that they should be working with you." —  Dr. Keith McCormick   Connect with Dr. Keith McCormick: Website: https://www.osteonaturals.com/   LinkedIn: https://www.linkedin.com/in/r-keith-mccormick-dc-433a2526/  Twitter: https://x.com/OsteoNaturals  Facebook: https://www.facebook.com/OsteoNaturals/     Books:  Great Bones: Taking Control of Your Osteoporosis: https://www.amazon.com/Great-Bones-Taking-Control-Osteoporosis/dp/B0BS8RJ2V3  The Whole-Body Approach to Osteoporosis: https://www.amazon.com/Whole-Body-Approach-Osteoporosis-Strength-Harbinger-ebook/dp/B0056JX49Y    Connect with Therese: Website:  www.criticallyspeaking.net Bluesky: @CriticallySpeaking.bsky.social Instagram: @criticallyspeakingpodcast Email: theresemarkow@criticallyspeaking.net    Audio production by Turnkey Podcast Productions.

    Dr. Dawn Sarno: Cyberscams and You

    In this episode, Therese Markow and Dr. Dawn Sarno, a leading expert on cyber scams, discuss the prevalence and detection of phishing scams. Dawn explains that phishing often targets older adults due to their perceived lack of tech savvy and higher financial stakes, but notes that younger adults are also vulnerable, often due to impulsivity and poor online habits. She highlights the rise of AI-generated deep fakes, which make scams more convincing and harder to detect. Dawn advises slowing down and verifying suspicious communications, emphasizing the importance of cyber hygiene practices, such as using strong passwords and multi-factor authentication. She also emphasizes the importance of vigilance and reporting scams to help prevent others from falling victim.    Key Takeaways: Differences and similarities between fraud, phishing, whaling, deep fakes, scams, and spam. Older adults are often targeted by scams, but they also typically have more to lose relative to a younger adult. While factors associated with age, like loneliness and abnormal cognitive decline, may make you more vulnerable to falling for a scam, Dr. Sarno's research generally suggests that there may not be a huge difference in detection abilities between younger and older adults.  Cyberscams are a numbers game. People often send out messages to large groups (such as everyone at a university) rather than targeting one person at a time.  If you notice that something's not right, report it, because this is going to help the social media platform or your organization's IT department find these scams and prevent them from reaching other people.   "One big thing I would stress is that if people are ever in doubt, they should never click a link or open an attachment, because that curiosity alone could lead them to have some problems." —  Dr. Dawn Sarno   Connect with Dr. Dawn Sarno: Professional Bio: https://sciences.ucf.edu/psychology/person/dawn-sarno/  LinkedIn: linkedin.com/in/dawn-sarno-790a1558    Connect with Therese: Website:  www.criticallyspeaking.net Bluesky: @CriticallySpeaking.bsky.social Instagram: @criticallyspeakingpodcast Email: theresemarkow@criticallyspeaking.net   Audio production by Turnkey Podcast Productions.

    Dr. Daniel Buchman: Do You Suffer From Chronic Pain?

    In this episode, Therese Markow and Dr. Daniel Buchman discuss chronic pain, affecting over 20% of the population in the US, Canada, and Europe. Chronic pain (persisting pain lasting over three months) includes conditions like arthritis, lower back pain, fibromyalgia, and phantom limb pain, among many others. Daniel highlights the challenges in pain assessment, the role of AI in pain management, and the ethical considerations, including bias in pain reporting. He notes that chronic pain increases suicide risk, and the conversation also touches on the stigma surrounding pain and opioid use.    Key Takeaways: Pain can come from an identifiable condition, but sometimes doesn't have a clear cause. Primary pain is the type of pain that is not explained by another disease. Secondary pain is pain that arises because of or is related to an underlying condition - perhaps injury, illness, disease, or other reason. When we talk about bias in health care providers, we also need to look at the broader societal bias that plays into those biases. As AI is used more in medicine, we do need to be aware of bias in the data sets that the AI is utilizing to learn and then use to make predictions.  Pain is a warning sign. It is not, in and of itself, bad. It is telling you that something might need to be addressed in your body.    "There isn't a blood test or a brain scan or anything that can determine how much pain somebody's in, or what it's like to experience that pain. This is subjective because it depends on the person, and it depends on a whole host of factors, not just their biology. It depends on their psychology, social factors, cultural factors, and gender is a big part of this as well." —  Dr. Daniel Buchman   Episode References:  Buchman, Daniel Z.a,b,c,d. 2025 AI and the ethics of techno-solutionism in pain management.

    Dr. David Hill: Peanut and Food Allergies in Children

    In this episode, Therese Markow and Dr. David Hill discuss the rise of peanut allergies in children. David explains that anaphylaxis, a severe allergic reaction, is common in children, often triggered by food. He emphasizes the importance of early allergen introduction to prevent allergies. The LEAP study from 2015 showed that introducing peanuts before six months reduces the risk of peanut allergy. They also discuss other common allergies and the fact that many children outgrow milk and egg allergies by age four.     Key Takeaways: The major allergens are milk, egg, soy, wheat, peanut, tree nut, fish, shellfish, and sesame, which are among the most common foods around the world. Thus we must do everything we can to prevent food allergy in the first place.  The part of the immune system that causes allergic reactions, was originally evolved to fight parasites.  There is still a lot to learn about what causes allergies. Multiple people are working on it now, and we will likely see, in the coming years, new risk factors emerging.   "In the first year, specifically somewhere between four to six months of age (once the child is able to handle a solid food in their mouth and swallow appropriately), at that point, we should start to introduce the major allergens." —  Dr. David Hill   Connect with Dr. David Hill: Professional Bio: https://www.chop.edu/doctors/hill-david-a  LinkedIn: https://www.linkedin.com/in/david-a-hill-md-phd-aab8744    Connect with Therese: Website:  www.criticallyspeaking.net Bluesky: @CriticallySpeaking.bsky.social Instagram: @criticallyspeakingpodcast Email: theresemarkow@criticallyspeaking.net   Audio production by Turnkey Podcast Productions.

    Dr. Fred Miller: The Autoimmune Disease Epidemic

    In this episode, Therese Markow and Dr. Fred Miller discuss the autoimmune disease epidemic, highlighting the economic burden and the rise of diseases like juvenile diabetes, lupus, and multiple sclerosis. Dr. Miller explains that autoimmune diseases occur when the immune system attacks the body, affecting various organs. He notes that there are at least 150 types of autoimmune diseases, with prevalence rates varying from 0.1% to 5% of the population - the exact number is unknown due to the need for better registries to track these diseases. Dr. Miller also discusses the role of genetics and environmental factors, lifestyle, and exposure to chemicals. He also mentions new treatments and the importance of lifestyle changes in prevention and management.    Key Takeaways: Virtually any organ system or tissue in the body can be damaged by the immune system, which makes autoimmune diseases difficult to assess, diagnose, and treat, as they can be so varied from person to person, and they can change over time. There are no fully agreed-upon definitions for autoimmune diseases. As such, we don't know how many there are, but most experts would say at least 150 different types. All of the autoimmune diseases are developed from interactions of many genes and many environmental risk factors in combination. Various environmental exposures might not change the genes themselves, but they might alter the normal way that genes are supposed to be turned on and off.   "We really don't have a way to measure all of these yet, but we are expanding the range of the types of exposures we can measure every year, and there are a few ways of capturing which exposures or mixtures of them we've experienced at what times, and by integrating all these together into a single number, this could help us understand the cumulative exposures that are that are probably important for the development of these diseases." —  Dr. Fred Miller   Connect with Dr. Fred Miller: Professional Bio: https://www.niehs.nih.gov/research/atniehs/labs/crb/pi/ea/staff/miller    Connect with Therese: Website:  www.criticallyspeaking.net Bluesky: @CriticallySpeaking.bsky.social Instagram: @criticallyspeakingpodcast Email: theresemarkow@criticallyspeaking.net   Audio production by Turnkey Podcast Productions.

    Dr. John Kisiel: Early Cancer Detection Liquid Biopsy

    In this episode, Therese Markow and Dr. John Kisiel discuss early cancer detection using liquid biopsies. Dr. Kisiel explains that liquid biopsies detect cancer signals in blood and urine, including tumor cells, fragments, proteins, and DNA. He highlights the FDA's approval of a blood test for colon cancer and the development of multi-cancer early detection tests. Dr. Kisiel notes that false positive and false negative rates vary by test. He emphasizes the potential of liquid biopsies to complement, not replace, standard screening methods and the need for further validation and clinical trials. Key Takeaways: Liquid biopsies have been used in the oncology community to test if cancer is still present, may need additional or more aggressive treatment, or if the cancer has come back. Each test will have its own false positive and false negative rate, partially based on where manufacturers set the thresholds for that positive/negative result. Peripheral blood-based tests for colon cancer do not detect polyps, and it's the finding and removing of polyps that actually offers the greatest preventive benefit, so that somebody never gets cancer in the first place.    "Another word of cautious optimism, I think that I, personally, and many other people active in the space really view these as an addition to standard of care cancer screening and not a replacement." —  Dr. John Kisiel   Connect with Dr. John Kisiel: Professional Bio: https://www.mayo.edu/research/faculty/kisiel-john-b-m-d/bio-00092659    Connect with Therese: Website:  www.criticallyspeaking.net Bluesky: @CriticallySpeaking.bsky.social Instagram: @criticallyspeakingpodcast Email: theresemarkow@criticallyspeaking.net   Audio production by Turnkey Podcast Productions.
