&lt;ul&gt;&lt;li&gt;
Dr. Dawn opens by examining how market competition is actually working in the weight loss drug sector. Novo Nordisk's Ozempic and Wegovy compete against Eli Lilly's Monjaro and ZepBound, with prices dropping nearly 50% as companies launch direct-to-consumer websites. The main barriers remain needles and refrigeration, driving development of oral versions. Novo's Wegovy pill awaits FDA approval for early 2026 launch at $150 monthly. Next-generation drugs show remarkable results: Eli's retatrutide causes 24% weight loss in 48 weeks, while Novo's Cagrisema combines semaglutide with amylin to reduce muscle loss. Pfizer paid $10 billion for Metsera's once-monthly drug despite significant side effects.
&lt;/li&gt;&lt;li&gt;
A quick fiber tip suggests adding plain psyllium to morning coffee for cardiovascular and microbiome benefits. Start with half a teaspoon and work up to two teaspoons (10 grams) over several weeks to avoid gas. The prebiotic fiber improves glucose tolerance and may reduce cancer risk.
&lt;/li&gt;&lt;li&gt;
UC San Diego scientists discovered why cancers mutate so rapidly despite being eukaryotic cells with protected chromosomes. The answer is chromothripsis, a catastrophic event where the enzyme N4BP2 literally explodes chromosomes into fragments. These reassemble incorrectly, generating dozens to hundreds of mutations simultaneously and creating circular DNA fragments carrying cancer-promoting genes. One in four cancers show evidence of this mechanism, with all osteosarcomas and many brain cancers displaying it. This explains why the most aggressive cancers resist treatment.
&lt;/li&gt;&lt;li&gt;
Research from 2013 shows any glucocorticoid use significantly increases venous thromboembolism risk, with threefold increases during the first month of use. The risk applies to new and recurrent clots, affecting both oral and inhaled steroids, though IV poses highest risk and topical the lowest. Joint injections fall somewhere between inhaled and oral. Anyone with prior blood clots should avoid steroids except for life-threatening situations like severe asthma attacks requiring ventilation.
&lt;/li&gt;&lt;li&gt;
A meta-analysis of 20 randomized controlled trials shows creatine supplementation helps older adults (48-84) maintain muscle mass when combined with weight training two to three times weekly. The supplement provides no benefit without exercise. Recommended dosing starts at 2 grams and works up to 5 grams daily. Vegans benefit most since they consume little meat or fish. Important caveat: creatine throws off standard kidney function tests (creatinine), so users should request cystatin C testing instead for accurate renal health assessment.
&lt;/li&gt;&lt;li&gt;
A new JAMA study suggesting risk-based mammogram screening is fatally flawed. First, researchers offered chemopreventative drugs like tamoxifen only to the high-risk group, contaminating the study design. Second, the demographics skewed heavily toward white college-educated women, missing the reality that Black women face twice the risk of aggressive breast cancer with 40% higher mortality. Third, wild-type humans failed to follow instructions—low-risk women continued getting annual mammograms anyway while high-risk women skipped recommended extra screenings. The conclusion of "non-inferior" outcomes is meaningless given poor adherence. Stick with annual mammograms, and consider alternating with MRIs for high-risk women.
&lt;/li&gt;&lt;li&gt;
The EAT-Lancet report condemns red meat based purely on observational data showing correlations with heart disease, cancer, and mortality. But people who eat lots of red meat differ dramatically from low consumers: they weigh more, smoke more, exercise less, and eat less fiber. Studies can't control for sleep quality, depression, or screen time. Notably, heavy meat eaters also die more in accidents, suggesting a risk-taking lifestyle phenotype. The inflammatory marker TMAO is higher in meat eaters, but starch is also pro-inflammatory. Eating red meat instead of instant ramen might improve health. A balanced diet with limited amounts beats epidemiology-based blanket statements.
&lt;/li&gt;&lt;li&gt;
Dr. Dawn grades Dr. Oz's performance as CMS administrator. Starting at minus one for zero relevant experience, he earns plus two for promoting diet, exercise, and gut health on his show. He studied intensively after nomination, calling all four previous CMS directors repeatedly and surrounding himself with experienced staff (plus one). He finalized Medicare rules favoring prevention over surgery and earned bipartisan praise as "a real scientist, not radical" (plus one). He divested healthcare holdings but kept some blind trust interests (minus 0.5). He's developing a CMS app and partnering with Google on a digital health ecosystem (plus one), but supports ending ACA subsidies that will raise premiums for millions (minus one). He correctly promoted COVID vaccines and contradicted Trump's Tylenol-autism claims (plus one). Final score: 3.5 out of 5 possible points, the only positive score for any Trump health administrator.

Weight Loss Drug Wars, Chromothripsis Cancer Discovery, Steroid Blood Clot Risks, Creatine for Elders, Mammogram Study Flaws, Red Meat Myths, and Dr. Oz's Report Card

<description>&lt;p&gt;Broadcast from KSQD, Santa Cruz on 12-11-2025:&lt;/p&gt;
&lt;ul&gt;&lt;li&gt;
Dr. Dawn presents colleague Dr. Paul Godin's essay on why US healthcare fails as a market system
. She explains that healthcare violates every assumption of functional markets: patients can't compare options during emergencies, information asymmetry prevents informed decisions, demand is inelastic when one has an urgent medical issue, and trust is essential to medicine and in direct conflict with profit incentives. Since 1988's Knox-Keen Act allowed for-profit healthcare, private equity has acquired and stripped hospitals, while administrative costs consume enormous resources fighting over payments rather than providing care. She contrasts this with European models like Switzerland and Germany where everyone must participate, insurers must accept all patients, and profit on basic coverage is limited.
&lt;/li&gt;&lt;li&gt;
She celebrates a vaccination success story: HPV vaccines have reduced cervical cancer by 50% over 30 years. The American Cancer Society now endorses self-collected vaginal samples for HPV screening, with an FDA-approved at-home kit from Teal Health allowing women to skip speculums and traditional Pap smears. Current guidelines recommend screening starting at age 25, with testing every five years after a negative result.
&lt;/li&gt;&lt;li&gt;
Dr. Dawn issues a health alert about multiple hospitalizations in Santa Cruz County from foraged wild mushrooms identified incorrectly by phone apps. She describes cholinergic toxicity symptoms: sweating, excessive salivation, pinpoint pupils, and abdominal cramping—signs requiring immediate emergency care rather than waiting it out.
&lt;/li&gt;&lt;li&gt;
She offers follow-up vaccine advice: "go in wet, then sweat." Hydrate before vaccination, then take a hot Epsom salt bath until sweat runs off your face. This helps eliminate adjuvants that cause post-vaccine fatigue and aches, which are often misinterpreted as catching illness from the vaccine itself.
&lt;/li&gt;&lt;li&gt;
Dr. Dawn expresses alarm that Kennedy's reconstituted ACIP nearly voted to eliminate hepatitis B vaccination at birth. She notes infants exposed to infected mothers have 99% infection rates, with half becoming chronically infected and half of those developing terminal cirrhosis or cancer. Testing pregnant women misses infections acquired during pregnancy, and 12-16% of delivering women have no test records. Major insurers have committed to covering birth vaccination through 2026 despite the panel's actions.
&lt;/li&gt;&lt;li&gt;
She offers holiday microbiome advice from researcher Karen Corbin: increase fiber intake through steel-cut oats, whole grain breads like Dave's Killer Bread, beans, apples, and alternative pastas made from lentils or garbanzo beans. Cooking potatoes ahead and reheating creates resistant starch that feeds beneficial gut bacteria, reduces inflammation, and even stimulates natural GLP-1 production.
&lt;/li&gt;&lt;li&gt;
Dr. Dawn reviews research proving health insurance saves lives. When the ACA's Medicaid expansion became optional by state, researchers could compare outcomes, finding 8% lower mortality and 19,000 fewer deaths in expansion states over four years. An accidental IRS experiment—sending insurance enrollment letters to only 85% of penalty payers—showed significantly lower mortality among those who subsequently got insured. Studies of gunshot and auto accident victims found uninsured patients died more often despite receiving identical emergency treatment.
&lt;/li&gt;&lt;li&gt;
She concludes with surprising cancer symptoms: chest pain specifically triggered by alcohol consumption may indicate Hodgkin's lymphoma, as vasodilation activates inflammatory chemicals in affected lymph nodes. Fractures from minimal trauma in people without osteoporosis warrant investigation, as 5% of cancers involve bone. Elevated calcium levels double cancer diagnosis risk in the following year and should prompt follow-up testing.
&lt;/li&gt;&lt;/ul&gt; </description>

Healthcare Market Failures and Private Equity, Hepatitis B Vaccine Politics, Research Proving Insurance Saves Lives, and Holiday Microbiome Tips

<description>&lt;p&gt;Broadcast from KSQD, Santa Cruz on 12-04-2025:&lt;/p&gt;
&lt;ul&gt;&lt;li&gt;
Dr. Dawn opens with an experimental vaccine that prevents severe allergic reactions by targeting IgE antibodies. The vaccine could eventually replace current monoclonal antibody treatments like omalizumab that require injections every two weeks.
&lt;/li&gt;&lt;li&gt;
She explains how adjuvants work in vaccines as additives that irritate the immune system enough to notice the vaccine target. Aluminum hydroxide is s common adjuvant. Modern vaccines use small pathogen fragments rather than whole organisms, requiring adjuvants to trigger adequate immune response. Dr. Dawn expresses concern about the US Advisory Committee on Immunization Practices reviewing aluminum adjuvants this week. A Danish study of over one million children finding no connection between aluminum with autism and ADHA contradicts RFK,Jr's public claims.She worries that removing aluminum could devastate vaccine effectiveness and children's health, noting that whenever vaccination rates drop, diseases like measles return to native circulation.
&lt;/li&gt;&lt;li&gt;
She recounts pertussis vaccine history—when Japan stopped vaccination due to rare adverse reactions (approximately one death per million doses), they lost about 5,000 children to whooping cough in the first year. The newer acellular vaccine using pathogen fragments plus adjuvants is safer but only lasts 4-5 years versus lifetime immunity from the older whole-cell version, necessitating "cocooning" strategies where everyone contacting newborns must be recently vaccinated.
&lt;/li&gt;&lt;li&gt;
Dr. Dawn describes a vaccine to prevent fentanyl from reaching the brain now starting clinical trials in the Netherlands. It pairs a fentanyl-like molecule with a carrier protein large enough to trigger antibody production. Once primed, the immune system attacks any fentanyl entering the blood, preventing highs and overdoses—potentially helping people in addiction recovery and those accidentally exposed through contaminated drugs.
&lt;/li&gt;&lt;li&gt;
She reports the first documented death from alpha-gal syndrome. Alpha-gal is a meat allergy triggered by Lone Star tick bites; the tick essentially vaccinates humans against the alpha-galactosidase protein found on beef and pork. Cases have increased since 2010 as climate change expands the tick's range northward, yet a 2023 survey found 42% of doctors had never heard of the condition.
&lt;/li&gt;&lt;li&gt;
Dr. Dawn highlights research from Edith Cowan University showing that blood drawn after exercise suppresses cancer cell growth when added to tumor cultures. In breast cancer survivors, plasma from high-intensity interval training or weight lifting caused cancer cells to stop growing or die; blood drawn before exercise had no effect. The key mechanism involves myokines, particularly IL-6, released by contracting muscles. A Stanford study found colon cancer survivors who exercised were 37% less likely to experience recurrence.
&lt;/li&gt;&lt;li&gt;
A caller asks about pig-to-human heart transplants and mask recommendations. Dr. Dawn clarifies that newer xenotransplant pigs have more genes edited to reduce rejection compared to the 2022 case. For masking, she recommends context-dependent use—especially in public restrooms where toilet flushing aerosolizes COVID-containing particles, transportation hubs, and hospitals, noting that COVID vaccination prevents death but not infection or long COVID.
&lt;/li&gt;&lt;li&gt;
She advises the same caller about spacing vaccines because adjuvant loads stack. Most vaccines can be combined safely, but she recommends against pairing COVID and Shingrix vaccines due to their heavy adjuvant content—wait at least ten days between them. She suggests inducing a sweat the night of vaccination through hot baths, saunas, or exercise to reduce adjuvant-related discomfort without diminishing antibody response.
&lt;/li&gt;&lt;li&gt;
Dr. Dawn discusses seasonal affective disorder. She recommends 5,000 units of vitamin D3 and morning light exposure.
&lt;/li&gt;&lt;li&gt;
She suggests that sun avoidance advice may have gone too far. A UK study of 3.36 million people found 12-15% lower mortality with greater UV exposure even accounting for skin cancer risk. A Swedish study following 30,000 women for 20 years found sun-seekers had half the mortality risk. Benefits may involve nitric oxide production lowering blood pressure, with each 1,000 km from the equator correlating with 5 mmHg higher blood pressure. Lack of bright outdoor light also contributes to childhood myopia, with rates exceeding 80% in some Asian cities.
&lt;/li&gt;&lt;li&gt;
Dr. Dawn concludes with Danish microbiologists at Copenhagen's Alchemist restaurant reviving an old Bulgarian practice of fermenting milk with live red wood ants. The resulting yogurt, cheese, and ice cream contain far more beneficial microbes than commercial products, with a complex lemony acidity. Only live ants work, and wild ants may carry parasites dangerous to humans.

Vaccine Science: Anaphylaxis Prevention, Adjuvant Controversies, Fentanyl Immunization, Exercise Fighting Cancer, and Sunlight's Hidden Benefits

<description>&lt;p&gt;Broadcast from KSQD, Santa Cruz on 11-20-2025:&lt;/p&gt;
&lt;ul&gt;&lt;li&gt;
Dr. Dawn discusses GLP-1 inhibitors like Zepbound and semaglutide showing unexpected benefits for addiction treatment beyond diabetes and weight loss. Patients in rehab report these drugs mute cravings for alcohol, cocaine, and cigarettes. Multiple studies show reduced substance abuse rates in users, with VA and NIH conducting trials examining brain activity and responses to triggers. With 80,000 annual drug overdose deaths and 48 million Americans having substance abuse disorders, these medications may revolutionize addiction treatment by dampening brain reward circuitry, though costs threaten healthcare budgets.
&lt;/li&gt;&lt;li&gt;
A Stanford twin study found those twins assigned a vegan diet had substantially lower cholesterol, insulin, and body weight compared to their omnivore twins after several months, with LDL dropping 15mg, four pounds more weight loss, and 20% lower insulin.
&lt;/li&gt;&lt;li&gt;
Dr. Dawn explains how a fungal disease decimating Central American frog populations caused 500% malaria increases in some areas. The fungus kills frogs by blocking skin electrolytes until hearts stop, eliminating tadpoles that eat mosquito larvae. Ecosystem collapses followed with algae blooms and snake population drops. She provides other examples showing how species losses affect human health, emphasizing the "one health" movement recognizing ecosystem health as fundamental to human wellbeing.
&lt;/li&gt;&lt;li&gt;
An Australian study found people aged 70+ who listen to or play music regularly had 39% lower dementia rates, though causation remains uncertain. Princeton research shows music activates multiple brain regions simultaneously. Learning instruments increases gray matter, and musical memory remains intact in advanced dementia since it's stored separately from other memories.
&lt;/li&gt;&lt;li&gt;
A caller discusses how modern screen-based activities provide less multisensory engagement than past social experiences like dances. Another caller describes Grover's disease causing persistent itchy skin with no known cause. Dr. Dawn recommends an elimination diet removing common allergens for one month, then reintroducing individually to identify food sensitivities triggering immune responses.
&lt;/li&gt;&lt;li&gt;
Dr. Dawn explains xenotransplantation advances with genetically edited pigs beginning full-scale kidney transplant trials. Companies use CRISPR to disable genes causing immune rejection and insert human genes promoting immune tolerance. With only 10% of global kidney patients receiving organs, these could provide unlimited supply. Other innovations include kidneys with thymus tissue to teach immune tolerance and external pig liver systems as transplant bridges.
&lt;/li&gt;&lt;li&gt;
She concludes noting research showing female dogs remember and prefer humans who demonstrate competence at tasks, while male dogs show no preference.
&lt;/li&gt;&lt;/ul&gt;

GLP-1 Drugs for Addiction Treatment, Ecosystem Health Connections, and Xenotransplantation Advances

<description>&lt;p&gt;Broadcast from KSQD, Santa Cruz on 11-13-2025:&lt;/p&gt;
&lt;ul&gt;&lt;li&gt;
Dr. Dawn discusses a New England Journal of Medicine study examining radiation exposure from medical imaging in over 4 million children showing increased hematological cancer risk. Head and brain CTs deliver highest bone marrow doses, with under-1-year-olds receiving 20 milligrays compared to background radiation of 1 milligray yearly. The study found 3,000 cancers in 4 million children over roughly 10 years, with relative risk increasing 1.6-fold per CT scan. However, methodological flaws include combining US and Canadian cohorts with different data quality, potential reverse causation where imaging detected pre-existing cancers, and arbitrary 6-month latency assumptions are significant flaws in this study.. Despite small absolute risk increases given low baseline cancer rates, she encourages parents to question necessity of repeat scans and request alternatives like MRI when appropriate.
&lt;/li&gt;&lt;li&gt;
She reports on cutting-edge CRISPR therapy using lipid nanoparticles to deliver molecular scissors targeting the ANGPTL3 gene controlling LDL cholesterol production. Recent setbacks in several other CRISPR trials raise issues for unexplained liver toxicity. Concerns include off-target gene editing effects and partially repaired DNA creating mutated proteins triggering autoimmune reactions. Dr. Dawn emphasizes restricting gene therapy to life-threatening genetic diseases with no alternatives until safety improves.
&lt;/li&gt;&lt;li&gt;
Stanford scientists used AI model Evo trained on 9 trillion gene samples to design 300 new bacteriophages from scratch, with 16 phages successfully killing E. coli bacteria. AI tools now predict protein structures, design custom drugs, create antivenoms, invent antibiotics, and break down PFAS forever chemicals.

An emailer shares the Rosencare model where hotel chain owner Harris Rosen created self-insured health coverage featuring direct provider contracting, imaging facilities charging one-third to one-half traditional costs, transparent pharmacy benefit management, and zero or $5 primary care copays. Employees receive proactive screening for colonoscopies, mammograms, cholesterol, diabetes, and hypertension during clinic visits. Ninety percent of medicines including insulin cost nothing, with remaining drugs $0-25, and hospital admissions cost flat $750. The model saved $600 million while providing superior preventive care by eliminating insurance middlemen and focusing on early chronic disease detection when 75-85% of costs originate.

Dr. Dawn explains abdominophrenic dyssynergia causing bloating unrelated to gas or food. The diaphragm descends and abdominal wall muscles relax, pushing organs forward after meals. CT scans showed lettuce-related bloating involved no intestinal gas changes but demonstrated this abnormal muscle reflex. Randomized trials showed biofeedback training with chest-lifting and abdominal wall contracting exercises before and after eating for four weeks improved symptoms 66%. She warns that constant bloating in postmenopausal women unrelated to eating requires ovarian cancer screening.

She discusses how genes drive personality using dopamine receptor gene DRD4 polymorphisms as an example. The 7-repeat variant present in 48% of Americans creates receptors binding dopamine poorly, associating with ADHD, pathological gambling, alcoholism, drug dependence, and bulimia, plus personality traits of novelty-seeking, impulsiveness, and optimism. The 2-repeat DRD4 variant common in Asia correlates with lower anger and higher forgiveness. DRD2 variations enhance the memory of negative outcomes, creating pessimistic bias and avoidance behavior.

She presents the KETO trial showing "lean mass hyper-responder phenotype" where very low-carbohydrate dieters averaging age 55 maintained LDL cholesterol of 272 for five years but showed identical coronary artery calcium scores and plaque burden as matched controls with LDL under 150. Despite extreme LDL elevation, the very low insulin levels from carbohydrate restriction prevent LDL oxidation, the inflammatory "loading" process enabling arterial damage. 
&lt;/li&gt;&lt;li&gt;
She concludes with unusual cancer symptom where recurrent pain in specific body locations after alcohol consumption, lasting 1-2 days, occurs in 5% of Hodgkin lymphoma patients and in other cancers when alcohol induced blood vessel dilation and inflammatory chemical release in cancer-containing lymph nodes causes pain after drinking.

Dr. Dawn discusses a New England Journal of Medicine study examining radiation exposure from medical imaging in over 4 million children showing increased hematological cancer risk. Head and brain CTs deliver highest bone marrow doses, with under-1-year-olds receiving 20 milligrays compared to background radiation of 1 milligray yearly. The study found 3,000 cancers in 4 million children over roughly 10 years, with relative risk increasing 1.6-fold per CT scan. However, methodological flaws include combining US and Canadian cohorts with different data quality, potential reverse causation where imaging detected pre-existing cancers, and arbitrary 6-month latency assumptions are significant flaws in this study.. Despite small absolute risk increases given low baseline cancer rates, she encourages parents to question necessity of repeat scans and request alternatives like MRI when appropriate.

She reports on cutting-edge CRISPR therapy using lipid nanoparticles to deliver molecular scissors targeting the ANGPTL3 gene controlling LDL cholesterol production. Recent setbacks in several other CRISPR trials raise issues for unexplained liver toxicity. Concerns include off-target gene editing effects and partially repaired DNA creating mutated proteins triggering autoimmune reactions. Dr. Dawn emphasizes restricting gene therapy to life-threatening genetic diseases with no alternatives until safety improves.

Stanford scientists used AI model Evo trained on 9 trillion gene samples to design 300 new bacteriophages from scratch, with 16 phages successfully killing E. coli bacteria. AI tools now predict protein structures, design custom drugs, create antivenoms, invent antibiotics, and break down PFAS forever chemicals. The research represents evolution through computation and requires guardrails on AI's ability to manipulate biological structures.
