We push back on claims that Tylenol or vaccines cause autism and explain how weak methods, conflicts of interest, and cherry-picked data fuel public panic. We also unpack why diagnoses have risen—broad criteria, screening, and access—not because of a new environmental villain.

• Summary of claims made at the press event and why they fail
• What the cited acetaminophen paper did and didn’t show
• Conflicts of interest, pay-to-publish venues, and bias
• Why correlation isn’t causation; confounding by indication
• Bradford Hill criteria applied to acetaminophen and autism
• Sibling-controlled studies as the strongest current evidence
• Amish and Cuba myths; diagnosis versus true prevalence
• DSM-5 changes driving higher autism diagnoses
• State-by-state variation explained by services and funding
• Vaccine safety evidence contrasted with myths
• Practical counseling: treat fever; use clear, strong evidence

Dr. Howard Harrell explores common questions about birth alternatives posed by Anna, a mom-to-be with questions, examining scientific evidence behind claims often found online that challenge evidence-based obstetric practices. The discussion separates facts from philosophy by analyzing actual research data on interventions like epidurals, oxytocin, and birthing positions.

• Maternal mortality has decreased 173-fold since 1850, coinciding with the rise of modern obstetrics
• The "cascade of interventions" theory isn't supported by scientific evidence
• Studies show epidurals don't increase cesarean delivery rates, contrary to popular belief
• Oxytocin augmentation, when properly used, can decrease cesarean rates rather than increase them
• Upright birthing positions don't show improved outcomes compared to lying on back
• Hospital/provider cesarean rates matter more than specific interventions in predicting your risk
• For low-risk pregnancies, intermittent rather than continuous fetal monitoring may reduce unnecessary interventions
• Best approach combines respecting physiologic birth while using appropriate medical tools when needed

Howard and Antonia explore the safety of medications during pregnancy and the controversial reporting requirements for breast density on mammograms, examining how science is being overshadowed by fear-mongering in healthcare decision-making.

• Examining the evidence behind avoiding fluconazole (Diflucan) in first trimester, finding that short courses likely pose minimal risk
• Discussing the important distinction between possibility and probability when evaluating medication safety in pregnancy
• Analyzing the wide variation in cesarean delivery rates across US counties, from 5.4% to over 53% for low-risk patients
• Critiquing politically-motivated FDA actions on SSRIs, food dyes, and other health policies not supported by scientific evidence
• Explaining why the FDA's requirement to notify women of dense breasts on mammograms may cause more harm than good
• Demonstrating how supplemental testing for women with dense breasts leads to false positives and unnecessary procedures
• Reviewing the historical development of prenatal diagnosis from early ultrasound to cell-free DNA testing
