Last updated: September 29, 2026 [Key Takeaways] Stroke incidence among U.S. adults ages 20-54 nearly doubled, climbing from 33.9 to 62.2 cases per 100,000 person-years between 1993-94 and 2020. Among young stroke patients, the share with high blood pressure rose from 47% to 60%, diabetes from 19% to 26%, atrial fibrillation from 1% to 6%, and drug use (mostly cannabis) from 5% to 40%. The 30-day death rate after stroke fell from 11.7% to 9.4%, with most of the improvement among people who had bleeding (hemorrhagic) strokes. The FAST warning signs (face drooping, arm weakness, speech difficulty, time to call 911) apply at any age, not only to older adults.

Last updated: September 28, 2026 [Key Takeaways] Cavities form when plaque bacteria convert sugars into acid that gradually wears down tooth enamel, and brushing technique plays a direct role in how much plaque is removed each day. Common errors—brushing too hard, rushing through the recommended two minutes, or missing the gumline and back molars—can leave plaque behind even when you brush regularly. The ADA-style baseline is brushing twice daily for two minutes with a soft-bristled brush at a 45-degree angle, replacing the brush every three to four months. Calcium-rich dairy, fluoride, crunchy produce, and xylitol are among the food categories associated with cavity prevention support, though several carry specific interaction or dosage cautions. Persistent tooth pain, visible holes or dark spots, and gum swelling are signs that warrant a dental visit rather than waiting it out.

Last updated: September 27, 2026 [Key Takeaways] Iron-containing multivitamin gummies are considered one of the most dangerous over-the-counter products for young children when swallowed in large amounts. Emergency warning signs after a possible overdose can include repeated vomiting, drowsiness, or trouble breathing and call for immediate medical attention. The national Poison Control hotline (1-800-222-1222) is available around the clock for guidance on a suspected supplement overdose. Storing gummy vitamins out of reach and never calling them "candy" may help reduce the chance of accidental ingestion. Children who already take iron supplements, have kidney or liver conditions, or use certain acne medications may face added risk when also given multivitamin gummies.

Last updated: September 23, 2026 [Key Takeaways] Colds and the flu are caused by viruses, and antibiotics are designed to act on bacteria, so they have no mechanism for shortening a viral illness. Every unnecessary course of antibiotics applies selective pressure that helps resistant bacteria survive and spread, a core driver of antibiotic resistance. Antibiotic-resistant infections are linked to more than 35,000 deaths in the United States each year and represent a growing public health burden. When a doctor declines to prescribe antibiotics for a cold, evidence-based supportive care — fluids, rest, over-the-counter symptom relief, and nasal saline — can still ease symptoms. If antibiotics are prescribed for a confirmed bacterial infection, taking them exactly as directed and not stopping early on your own helps treat the infection fully and lowers the chance of relapse — the right course length is a decision for the prescribing clinician, not a general rule for preventi...
