Objective: To evaluate the effectiveness of the use of adjuvant ozone therapy in the healing process of wounds resulting from periodontal and peri-implant surgical procedures by answering the following focused question: "Can adjuvant ozone therapy improve wound healing outcomes related to periodontal and peri-implant surgical procedures?".
Method And Materials: MEDLINE (via PubMed), EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched, without language restriction, for peer-reviewed articles published until 23 March 2022, in addition to manual search. Only controlled clinical trials (randomized or not) were considered. The risk of bias was evaluated by the Cochrane risk-of-bias tool for RCTs - version 1 (RoB1). Data were pooled into evidence tables and a descriptive summary was presented.
Results: Of the 107 potentially eligible records, only seven studies were included. Four addressed free/deepithelialized gingival grafts with a palatal donor area, two evaluated implant sites, and one comprised gingivectomy and gingivoplasty. A total of 225 patients were evaluated in the included studies, considering control and test groups (ozone and other adjuvant therapies for comparison). Ozone therapy had a positive effect on outcomes directly or indirectly related to periodontal/peri-implant surgical wound healing. Furthermore, it could also increase the stability of immediately loaded single implants installed in the posterior mandible.
Conclusion: In general, ozone therapy seems to both accelerate the healing processes of periodontal/peri-implant wounds and increase the secondary stability of dental implants; however, considering the limited evidence available and the risk of bias in the included studies (none classified as low risk), a definitive conclusion cannot be drawn.

Air pollution is a well-established risk factor for lung cancer, but limited evidence exists on its impact on the treatment of lung cancer. The objective of this study was to investigate the impact of key pollutants on the efficacy of PD-1/PD-L1 inhibitor immunotherapy in non-small cell lung cancer (NSCLC) patients, thereby providing clinicians with evidence to potentially enhance the efficacy of PD-1 therapy and inform policy decisions for cancer care. To this end, we conducted a study involving 361 NSCLC patients who received PD-1/PD-L1 inhibitor immunotherapy, examining the correlation between air pollution exposure and progression-free survival (PFS) following immunotherapy treatment.

Although immunotherapy has revolutionized clinical cancer treatment, the efficacy is limited due to the lack of tumor-associated antigens (TAAs) and the presence of compensatory immune checkpoints. To overcome the deficiency, a nano-system loaded with ozone and CD47 inhibitor RRx-001 is designed and synthesized. Upon irradiation, reactive oxygen species (ROS) generated from ozone reacts with nitric oxide (NO) metabolized from RRx-001 to form reactive nitrogen species (RNS), which presents a much stronger cell-killing ability than ROS.

Doxorubicin-induced cardiotoxicity (DIC) is one of the most severe side effects of doxorubicin, yet the underlying mechanisms remain incompletely understood. Our results showed that Neutrophil extracellular traps (NETs) accumulated in plasma and cardiac tissue after doxorubicin treatment. The inhibition of NETs formation by Pad4 gene ablation significantly attenuated doxorubicin-induced arrhythmia, prolonged survival time and reduced the levels of Troponin T (cTnT) and creatine kinase MB (CK-MB) in mice.

Background: Numbness and tingling secondary to chemotherapy-induced peripheral neuropathy (CIPN) are frequent side effects that limit chemotherapy treatment and quality of life. Successful treatments for CIPN are limited. This preliminary report shows the potential long-term effects of ozone treatment in the management of persistent numbness and tingling secondary to CIPN.

Background: Intracanal medicament (ICM) eliminates remaining bacteria and their toxins that were not removed by chemomechanical preparation during endodontic treatment.
Aim: The aim of this study was to compare and evaluate the removal of ozonated oil-based, silicone oil-based, and distilled water-based ICM with two calcium chelators, i.e.
