PubMed, maintained by the National Library of Medicine (NLM) at the National Institutes of Health (NIH), is the largest and most comprehensive free database for biomedical literature.

Actionable Steps:

  1. Basic Search: Start with broad terms like “leukodystrophy research” or “leukodystrophy therapy.”
    • Example: Type “leukodystrophy gene therapy” into the PubMed search bar.
  2. Refine with Specific Leukodystrophies: If you’re interested in a particular type, add its name.
    • Example: “Metachromatic Leukodystrophy clinical trial” or “Adrenoleukodystrophy biomarker.”
  3. Utilize MeSH Terms: Medical Subject Headings (MeSH) are a controlled vocabulary used by PubMed to index articles. Using MeSH terms ensures you capture all relevant articles, even if authors use different terminology.
    • How to find MeSH terms: Search for your topic in PubMed, then look at the “MeSH terms” listed in relevant articles. Alternatively, use the MeSH database directly (accessible via the PubMed homepage).

    • Example: For “leukodystrophy,” common MeSH terms include “Leukodystrophies,” “Myelin Sheath,” or specific disease names like “Adrenoleukodystrophy.”

  4. Filter Results: On the left-hand side, you’ll find filters for publication date (e.g., “Last 5 years,” “Last year”), article type (e.g., “Clinical Trial,” “Review”), and more. Prioritize recent publications and review articles for a comprehensive overview.

    • Example: After searching “leukodystrophy therapy,” filter by “Review” to get summary articles or “Clinical Trial” to see intervention studies.
  5. Set Up Alerts: Create a PubMed alert (requires a free NCBI account) for your specific search terms. You’ll receive email notifications when new articles matching your criteria are published.
    • Example: Set an alert for “leukodystrophy novel treatment” to stay updated on emerging therapies.
