To map the literature about photodynamic therapy in treating diabetic foot ulcers. Diabetic foot ulcers get constantly infected, thus culminating in hospitalizations and amputations. Photodynamic therapy is an antimicrobial treatment that may assist in the healing process. A search of nine electronic information sources was made as determined by the Joanna Briggs Institute. Two independent researchers accomplished a screening of studies with the support of Rayyan. The data were analyzed through Iramutec®. The sample consisted of 27 studies. Photodynamic therapy was identified as safe and effective, with the ability to reduce pain, edema, exudate, extent of the injury region, microbial load, and the risks of infection, osteomyelitis, and amputations. The capacity of photodynamic therapy to relieve symptoms, decrease risks of complications, and accelerate the healing process highlights its potential positive impact on clinical practice.

Department of Prosthodontics, Faculty of Dentistry, Sabzevar University of Medical Sciences, Sabzevar, Iran.
Purpose: This systematic review and meta-analysis aimed to assess the gingival crevicular fluid (GCF) level of tumor necrosis factor-alpha (TNF-alpha) as a valuable inflammatory cytokine for estimation of the efficacy of adjunctive antimicrobial photodynamic therapy (aPDT) in stage II-IV periodontitis patients.
Methods: This review was conducted in accordance with the PRISMA statements, and registered in PROSPERO (CRD42022321211). An electronic search was conducted for articles comparing the efficacy of aPDT versus scaling and root planing (SRP) published up until June 2023.
Engineered Microalgae for Photo-Sonodynamic Synergistic Therapy in Breast Cancer Treatment.

Dynamic therapies such as photodynamic therapy (PDT) and sonodynamic therapy (SDT) have potential in cancer treatment. Microalgae have attracted increasing attention because of their high active mobility, flexibility in terms of functionality, and good biocompatibility. In this study, surface-engineered microalgae Chlorella vulgaris (Chl) modified with metal‒organic framework (MOF) nanoparticles (denoted Chl-MOF) are successfully developed for synergistic photo-sonodynamic therapy and immunotherapy.

Anti-vascular endothelial growth factor (VEGF) agents administered as either monotherapy or combination with verteporfin photodynamic therapy (PDT) are the 2 dominant treatment for polypoidal choroidal vasculopathy (PCV); However, controversies remain due to small sample sizes and inconsistency in prognosis from randomized controlled trials (RCTs). In accordance with the PRISMA statement, we investigated the efficacy of PDT plus anti-VEGF combination with anti-VEGF monotherapy. This study was accepted by the International Prospective Register of Systematic Reviews (CRD42023471362).

Background: ALA-PDT has been widely used in mild to moderate acne vulgaris worldwide. However, very few studies used riboflavin-PDT to treat acne vulgaris.
Objective: To investigate the efficacy and adverse events of riboflavin-PDT to treat mild to moderate facial acne, and compare it with ALA-PDT on a non-inferiority basis.
Aggregation assisted enhancement of singlet oxygen generation by 4-ethynylphenyl substituted porphyrin photosensitizer for photodynamic therapy.

Modulating the photophysical properties of photosensitizers is an effective approach to enhance singlet oxygen generation for photodynamic therapy. Porphyrins are the most widely used photosensitizers due to their biocompatible nature. Aggregation-induced emission (AIE) characteristics of photosensitizers are one of the advantageous features that will enhance fluorescence, intersystem crossing, and efficient triplet state generation.
