Tóm tắt	A letter to the editor is a brief, rapid communication (typically <500 words) published in academic journals, usually in response to a recently published article. Letters enable scholars to raise questions, offer corrections, present supporting or contrary evidence, or highlight implications of published work. Unlike full research articles, letters are faster to publish (weeks to months), making them valuable for timely scientific discourse. Letters are indexed in major databases (PubMed, Scopus, Web of Science) and count as publications, though carrying lower weight than original research articles. The letter format dates to the earliest academic journals and remains a vital vehicle for scholarly dialogue.	Peer review is the process by which manuscripts are evaluated by experts in the same field before publication in academic journals. Reviewers assess the manuscript's scientific merit, methodology, clarity, and contribution to the field. Established in 1665 with the first scientific journal (Philosophical Transactions of the Royal Society), peer review remains the gold standard for quality control in academic publishing. Despite ongoing criticism and proposals for alternatives, peer review continues to filter low-quality and unethical work, though it is imperfect and sometimes slow.
