Statistical Flaws in JAMA Vaccine-Cardiac Study, Chain Psilocybin Case Report in Alzheimer's, and Gut Microbiome Effects on Female Fertility
Broadcast from KSQD, Santa Cruz on 7-16-2026:
Dr. Dawn dissects a June 2026 JAMA Internal Medicine paper that claimed simultaneous flu and COVID vaccination in veterans reduced cardiac events, arguing the retrospective natural-experiment design cannot support causal conclusions. The 20% versus 2% dropout rates between groups signal fundamentally non-comparable populations, and the divergence in cardiac events starting within a month of vaccination is clinically implausible—suggesting an X-factor other than vaccine effect is driving the numbers.
Dr. Dawn delivers a pointed critique of a major chain pharmacy—part of a vertical healthcare monopoly—for creating deliberate friction around controlled-substance prescriptions through claims of stock shortages, unnecessary prior authorizations, and phantom "clarification" requests. She acknowledges the real paperwork burden of DEA compliance (quarterly reporting, six-month inspections, legitimate-need documentation) but argues chains are pushing pain patients away rather than doing due diligence, while independent pharmacies are closing at alarming rates in California.
Following up on last week's Kampo medicine caller, Dr. Dawn reports research on Goshajinkigan showing it suppresses voltage-gated sodium channels at the motor end plate, functioning as a muscle relaxant used clinically in Japan for low back pain, extremity numbness, and chemotherapy- and diabetic-induced neuropathy.
An emailer asks about a case report of an 80-year-old woman with 10-year Alzheimer's whose function dramatically improved after 5g oral psilocybin (Enigma strain), regaining conversation, continence, and autonomous dressing. Dr. Dawn notes plausible mechanisms (neuroplasticity, anti-inflammatory action, elevated BDNF) but cautions the diagnosis was clinical rather than confirmed with imaging or CSF markers, and recommends the emailer pursue exercise and sleep optimization for word-finding difficulties instead.
An emailer asks how to reassure her chemically-hypersensitive adult son that their remediated apartment is safe. Dr. Dawn recommends commercial ERMI (Environmental Relative Moldiness Index) testing along baseboards where spores concentrate, plus urine mycotoxin testing on the parents themselves to demonstrate objectively low exposure levels.
