Broadcast from KSQD, Santa Cruz on 10-08-2026:

• Dr. Dawn criticizes UnitedHealth's acquisition of Aetna and the resulting vertical healthcare monopoly, noting that Trump's cancellation of the Biden-era Medicare Part D subsidy will raise average premiums roughly $20/month, while the much-touted Pfizer and Lilly price-reduction deals contain confidentiality clauses, FOIA exemptions, and expiration dates tied to thIS administration's end in January 2029.
• An emailer asks whether magnesium L-threonate (Magtein) is worth the price over magnesium glycinate; Dr. Dawn explains that threonate carries magnesium across the blood-brain barrier for cognitive and sleep benefits (with research showing a 7.5-year reduction in cognitive age), while glycinate works through glycine as a GABA precursor—recommending titrating glycinate to tolerance before investing in threonate.
• A Kobe University functional MRI study of 87 people imagining future events found that optimists share remarkably similar brain-activity patterns in the medial prefrontal cortex, while pessimists show highly individualized patterns—suggesting optimists more clearly distinguish positive from negative events and process negatives abstractly rather than emotionally.
• A University of Calgary double-blind trial transplanted healthy-donor fecal microbiota into 35 bipolar-disorder patients in depressive phase, with most showing improvement at six months; a related 2024 IBS study showed no benefit at six months but significant separation from controls at 12 months, suggesting ecosystem effects rather than any single "magic bacterium."
• An emailer asks about managing a new Lp(a) diagnosis of 50 mg/dL; Dr. Dawn recommends a stress echocardiogram over coronary calcium scoring to assess existing disease, with phospholipase A2 as the best blood test for soft plaque.
  Regarding Lp(a), Dr.Dawn suggests waiting for long-term safety data before using the new Lp(a)-lowering drugs, and instead advises low-dose aspirin plus high-quality fish oil (bought in small containers to avoid rancidity)
• Three eye symptoms that warrant immediate ER evaluation:
  1: Wavy or curved straight lines (signaling a lifting retina from wet macular degeneration or diabetic eye disease), with Dr. Dawn recommending daily glances at an Amsler grid or crossword puzzle lines for early detection. 2: Eye pain with moving from indoor to sunny outside light or pain relieved by dimming the lights which can indicate inflamation of the pupillary muscles (iritis).
  3: A sudden shower of numerous swarming dots in one eye as a sudden increase in floaters can indicate bleeding within the eyeball.
