Can supplements slow Parkinson’s disease? Review reveals where the evidence stands

Dietary supplements are widely used by people with Parkinson’s disease, but this review finds that none have yet been proven to slow disease progression. Biotics, nicotinamide riboside, and omega-3 fatty acids combined with vitamin E show the most promise, but larger, longer, and better-designed trials are needed.

Thyroid hormone profiles provide critical prognostic clues for patients facing liver failure

Early and accurate prognostic assessment is crucial to prevent disease progression in liver failure. Thyroid hormones (THs), particularly triiodothyronine (T3), are key metabolic regulators and play an important role in liver regeneration. Liver failure is frequently complicated by non‑thyroidal illness syndrome (NTIS), characterized by low T3 with normal or slightly elevated TSH and T4.
