ORIGINAL ANALYSIS
From Miracle to Mystery: What No One Tells You About Peptide Therapy
Peptide therapy is rapidly gaining popularity as the latest “miracle” health trend, promising benefits ranging from faster injury recovery to improved skin, weight loss, and athletic performance. Short chains of amino acids that naturally occur in the body, peptides play important roles in hormone regulation and cellular signalling, yet many of the injectable forms promoted online remain unregulated and lack robust clinical evidence. Despite growing use of compounds such as BPC-157 and TB-500 in sports medicine and orthopaedics, most supporting evidence comes from small human studies or animal research, limiting confidence in their safety and effectiveness. Potential risks include allergic reactions, improper dosing, unknown drug interactions, and complications from self-injection. While early findings appear promising for tissue healing and inflammation, current evidence remains insufficient, highlighting the need for rigorous randomized trials before widespread clinical adoption.

Effect of Powdered Vancomycin in Surgical Site Infections in Posterior Thoracic/Lumbar Spine Surgery
Five randomized controlled trials including 1677 patients undergoing posterior thoracic or lumbar spine surgery were included in this systematic review and meta-analysis comparing topical powdered vancomycin applied to the surgical wound versus standard surgical prophylaxis without vancomycin. Pooled outcomes of interest included incidence of surgical site infections (SSI) and evaluation of safety outcomes and microbiological profiles of infections. The pooled analysis demonstrated that powdered vancomycin significantly reduced surgical site infections, with 16 infections in the intervention group vs. 34 infections in the control group. Overall, the findings suggest that local application of vancomycin powder reduces SSI risk in thoracic and lumbar spine surgeries, although further research is needed to confirm long-term safety and broader applicability.
