• Optimizing Brain Biology Through Near-Infrared-Induced Mitochondrial Melatonin Synthesis: A Hypothesis Paper (2026) · doi

  As a narrative hypothesis paper, this work provides an interpretive synthesis rather than exhaustive systematic coverage. Study selection reflects the author's judgment and may not capture all relevant literature. The emphasis on English-language publications may have excluded important non-English studies. The integrative approach, while permitting novel synthesis across traditionally separate fields, may underemphasize within-field controversies or methodological debates. The hypothesis presented, while mechanistically plausible and consistent with available evidence, represents a synthesis that has not been experimentally validated as a unified system. Individual components have varying levels of support: CCO photobiology and melatonin antioxidant properties are well-established, mitochondrial melatonin synthesis is supported by strong recent evidence, but the integrated NIR-responsive cascade remains hypothetical. Readers should recognize the distinction between established findings and proposed mechanisms.

• Sustaining Infection Prevention and Control Post-Accreditation: A Systematic Review and Meta-Analysis of Global Longitudinal Outcomes (2026) · doi

  The study excluded cross-sectional designs, which may limit the generalizability of findings and exclude relevant evidence from the synthesis.
