Review
Our hypothesis that controlled ozone applications interfere with the redox balance of a biological organism (first published in 1998 with a preclinical trial on protecting the liver from CCl intoxication) has been verified over the past two decades in reactive oxygen species (ROS)-induced mitochondrial pathologies, such as rheumatoid arthritis, osteoarthritis, aging processes and type 2 diabetes, and in the prevention of intoxications. Low-dose ozone acts as a redox bioregulator: the restoration of the disturbed redox balance is comprehensible in a number of preclinical and clinical studies by a remarkable increase in the antioxidant repair markers, here mainly shown as a glutathione increase and a reduction in oxidative stress markers, mainly malondialdehyde. The mechanism of action is shown, and relevant data are displayed, evaluated and comprehensively discussed: the repair side of the equilibrium increases by 21% up to 140% compared to the non-ozone-treated groups and depending on the indication, the stress markers are simultaneously reduced, and the redox system regains its balance.

Review
Current evidence suggests that airborne pollutants have a detrimental effect on fetal growth through the emergence of small for gestational age (SGA) or term low birth weight (TLBW). The study's objective was to critically evaluate the available literature on the association between environmental pollution and the incidence of SGA or TLBW occurrence. A comprehensive literature search was conducted across Pubmed/MEDLINE, Web of Science, Cochrane Library, EMBASE, and Google Scholar using predefined inclusion and exclusion criteria. The methodology adhered to the PRISMA guidelines. The systematic review protocol was registered in PROSPERO with ID number: CRD42022329624. As a result, 69 selected papers described the influence of environmental pollutants on SGA and TLBW occurrence with an Odds Ratios (ORs) of 1.138 for particulate matter ≤ 10 μm (PM), 1.338 for particulate matter ≤ 2.5 μm (PM), 1.173 for ozone (O), 1.287 for sulfur dioxide (SO), and 1.226 for carbon monoxide (CO). All eight studies analyzed validated that exposure to volatile organic compounds (VOCs) is a risk factor for SGA or TLBW. Pregnant women in the high-risk group of SGA occurrence, i.e., those living in urban areas or close to sources of pollution, are at an increased risk of complications. Understanding the exact exposure time of pregnant women could help improve prenatal care and timely intervention for fetuses with SGA. Nevertheless, the pervasive air pollution underscored in our findings suggests a pressing need for adaptive measures in everyday life to mitigate worldwide environmental pollution.

Review
Ozone has been used as an antibacterial agent for various purposes in healthcare. The use of ozone in dental practice is also well-established. Its utilization as a mouth rinse needs to be explored for further application in clinical practice, especially for cases of gingivitis, a common complaint. This systematic review aims to analyze the literature on the effects of ozonated water in managing gingival inflammation and bleeding across diverse populations. A systematic search adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted in PubMed, MEDLINE, Embase, and Cochrane. Studies published between January 2012 and December 2023 employing ozonated water as a treatment for gingivitis or gingival bleeding were included. Five studies met the inclusion criteria, demonstrating the varied efficacy of ozonated water. While some studies showed promising results in reducing bleeding and gingival inflammation, others indicated limitations compared to chlorhexidine. Methodological heterogeneity and lack of standardization were notable. The evidence suggests potential benefits of ozonated water in managing gingival inflammation and bleeding, but methodological variations hinder conclusive findings. Long-term studies with larger sample sizes and standardized protocols are needed to establish the effectiveness of ozonated water as an adjunctive therapy for gingival health.

Review
BACKGROUND
Low back pain and sciatica caused by herniated lumbar discs (HLDs) are common complaints among patients visiting pain clinics. Among the various therapeutic methods, intradiscal ozone injections have emerged as an effective alternative or additional treatment option for HLDs.
OBJECTIVE
This meta-analysis aimed to investigate the effectiveness of intradiscal ozone injections in the treatment of HLDs.
METHODS
We searched the PubMed, Embase, Cochrane Library, and Scopus databases for relevant studies published until January 25, 2024. We included studies that investigated the efficacy of intradiscal ozone injections in patients with HLDs. We evaluated the methodological quality of individual studies using the Cochrane Collaboration tool.
RESULTS
At ⩾ 6 months after treatment, the therapeutic effect of intradiscal ozone injections in patients with HLDs was greater than that of steroid injections (treatment success rate, 6 months: odds ratio = 3.95, 95% confidence interval [CI] [2.44, 6.39], P< 0.01) or conventional medications (changes in the Visual Analog Scale [VAS], 6 months: standardized mean difference [SMD] = 1.65, 95% CI [1.08, 2.22], P< 0.01; 12 months: SMD = 1.52, 95% CI [0.96, 2.08], P< 0.01) but similar to that of microdiscectomy (changes in VAS, 18 months: SMD =-0.05, 95% CI [-0.67, 0.57], P= 0.87). At < 6 months after treatment, the reduction in the VAS score after intradiscal ozone injections was higher than that after steroid injections (changes in VAS, 1 month: SMD = 2.53, 95% CI [1.84, 3.21], P< 0.01).
CONCLUSION
Intradiscal ozone injections may be a useful therapeutic tool in patients with HLDs. Compared with other conventional treatment methods such as steroid injections and oral medications, intradiscal ozone injection has great long-term (⩾ 6 months) effectiveness.

UNLABELLED
Air pollution is a major cause of specific deaths worldwide. This review article aimed to investigate the results of cohort studies for air pollution connected with the all-cause, cardio-respiratory, and lung cancer mortality risk by performing a meta-analysis. Relevant cohort studies were searched in electronic databases (PubMed/Medline, Web of Science, and Scopus). We used a random effect model to estimate the pooled relative risks (RRs) and their 95% CIs (confidence intervals) of mortality. The risk of bias for each included study was also assessed by Office of Health Assessment and Translation (OHAT) checklists. We applied statistical tests for heterogeneity and sensitivity analyses. The registration code of this study in PROSPERO was CRD42023422945. A total of 88 cohort studies were eligible and included in the final analysis. The pooled relative risk (RR) per 10 μg/m increase of fine particulate matter (PM) was 1.080 (95% CI 1.068-1.092) for all-cause mortality, 1.058 (95% CI 1.055-1.062) for cardiovascular mortality, 1.066 (95%CI 1.034-1.097) for respiratory mortality and 1.118 (95% CI 1.076-1.159) for lung cancer mortality. We observed positive increased associations between exposure to PM, PM, black carbon (BC), and nitrogen dioxide (NO) with all-cause, cardiovascular and respiratory diseases, and lung cancer mortality, but the associations were not significant for nitrogen oxides (NOx), sulfur dioxide (SO) and ozone (O). The risk of mortality for males and the elderly was higher compared to females and younger age. The pooled effect estimates derived from cohort studies provide substantial evidence of adverse air pollution associations with all-cause, cardiovascular, respiratory, and lung cancer mortality.

IMPORTANCE
Climate change may increase the risk of adverse cardiovascular outcomes by causing direct physiologic changes, psychological distress, and disruption of health-related infrastructure. Yet, the association between numerous climate change-related environmental stressors and the incidence of adverse cardiovascular events has not been systematically reviewed.
OBJECTIVE
To review the current evidence on the association between climate change-related environmental stressors and adverse cardiovascular outcomes.
EVIDENCE REVIEW
PubMed, Embase, Web of Science, and Cochrane Library were searched to identify peer-reviewed publications from January 1, 1970, through November 15, 2023, that evaluated associations between environmental exposures and cardiovascular mortality, acute cardiovascular events, and related health care utilization. Studies that examined only nonwildfire-sourced particulate air pollution were excluded. Two investigators independently screened 20 798 articles and selected 2564 for full-text review. Study quality was assessed using the Navigation Guide framework. Findings were qualitatively synthesized as substantial differences in study design precluded quantitative meta-analysis.
FINDINGS
Of 492 observational studies that met inclusion criteria, 182 examined extreme temperature, 210 ground-level ozone, 45 wildfire smoke, and 63 extreme weather events, such as hurricanes, dust storms, and droughts. These studies presented findings from 30 high-income countries, 17 middle-income countries, and 1 low-income country. The strength of evidence was rated as sufficient for extreme temperature; ground-level ozone; tropical storms, hurricanes, and cyclones; and dust storms. Evidence was limited for wildfire smoke and inadequate for drought and mudslides. Exposure to extreme temperature was associated with increased cardiovascular mortality and morbidity, but the magnitude varied with temperature and duration of exposure. Ground-level ozone amplified the risk associated with higher temperatures and vice versa. Extreme weather events, such as hurricanes, were associated with increased cardiovascular risk that persisted for many months after the initial event. Some studies noted a small increase in cardiovascular mortality, out-of-hospital cardiac arrests, and hospitalizations for ischemic heart disease after exposure to wildfire smoke, while others found no association. Older adults, racial and ethnic minoritized populations, and lower-wealth communities were disproportionately affected.
CONCLUSIONS AND RELEVANCE
Several environmental stressors that are predicted to increase in frequency and intensity with climate change are associated with increased cardiovascular risk, but data on outcomes in low-income countries are lacking. Urgent action is needed to mitigate climate change-associated cardiovascular risk, particularly in vulnerable populations.

Review
Cervical intervertebral disc herniation is a common condition and most often presents as neck or upper limb pain causing varying levels of disability and dysfunction. Percutaneous injection of ozone into the intradiscal space is a novel and minimally invasive technique for managing this condition and can be an effective alternative to surgical management. A literature search was done using the keywords ozone disc nucleolysis of cervical intervertebral lesions, and five studies were selected based on the inclusion and exclusion criteria. Meta-analysis was performed to determine safety, effectiveness, and symptomatic relief (determined based on the visual analog scale (VAS)) with the publication bias being removed. Subjects treated with ozone therapy showed significant reduction (p < 0.0001) in VAS score as compared to baseline VAS score with a standardized mean difference of 2.78 (95% CI = 1.48 to 4.07; Z value = 4.20). Ozone nucleolysis is a minimally invasive, relatively safe, and optimally effective treatment option for reducing the pain related to cervical disc. Intradiscal ozone therapy can be considered an alternative treatment modality, and well-designed, randomized clinical trials are required to confirm the long-term superiority of ozone therapy against other treatment modalities available for cervical disc herniation.

Review
Percarbonate encompasses sodium percarbonate (SPC) and composite in-situ generated peroxymonocarbonate (PMC). SPC emerges as a promising alternative to hydrogen peroxide (HO), hailed for its superior transportation safety, stability, cost-effectiveness, and eco-friendliness, thereby becoming a staple in advanced oxidation processes for mitigating water pollution. Yet, scholarly literature scarcely explores the deployment of percarbonate-AOPs in eradicating organic contaminants from aquatic systems. Consequently, this review endeavors to demystify the formation mechanisms and challenges associated with reactive oxygen species (ROS) in percarbonate-AOPs, alongside highlighting directions for future inquiry and development. The genesis of ROS encompasses the in situ chemical oxidation of activated SPC (including iron-based activation, discharge plasma, ozone activation, photon activation, and metal-free materials activation) and composite in situ chemical oxidation via PMC (namely, HONaHCO/NaCO, peroxymonosulfate/NaHCO/NaCO systems). Moreover, the ROS generated by percarbonate-AOPs, such as •OH, O, CO, HO, O, and HCO, can work individually or synergistically to disintegrate target pollutants. Concurrently, this review systematically addresses conceivable obstacles posing percarbonate-AOPs in real-world application from the angle of environmental conditions (pH, temperature, coexisting substances), and potential ecological toxicity. Considering the outlined challenges and advantages, we posit future research directions to amplify the applicability and efficacy of percarbonate-AOPs in tangible settings. It is anticipated that the insights provided in this review will catalyze the progression of percarbonate-AOPs in water purification endeavors and bridge the existing knowledge void.

Review
Research has indicated that certain environmental exposures may increase the risk of unprovoked seizures and new onset epilepsy. This study aimed to synthesize the literature that has estimated the associations between short- and long-term exposure to outdoor air and noise pollution and the risk of unprovoked seizures and new onset epilepsy. We searched Embase, MEDLINE, Scopus, Web of Science, BIOSIS Previews, Latin American and Caribbean Health Sciences Literature, Proquest Dissertations and Theses, conference abstracts, and the gray literature and conducted citation tracing in June 2023. Observational and ecological studies assessing the associations of air and noise pollution with unprovoked seizures or new onset epilepsy were eligible. One reviewer extracted summary data. Using fixed and random effects models, we calculated the pooled risk ratios (RRs) for the studies assessing the associations between short-term exposure to air pollution and unprovoked seizures. Seventeen studies were included, 16 assessing the association of air pollution with seizures and one with epilepsy. Eight studies were pooled quantitatively. Ozone (O; RR = .99, 95% confidence interval [CI] = .99-.99) and nitrogen dioxide (NO) exposure adjusted for particulate matter (RR = 1.02, 95% CI = 1.01-1.02) on the same day, and carbon monoxide (CO) exposure 2 days prior (RR = 1.12, 95% CI = 1.02-1.22), were associated with seizure risk. A single study of air pollution and epilepsy did not report a significant association. The risk of bias and heterogeneity across studies was moderate or high. Short-term exposure to O, NO, and CO may affect the risk of seizures; however, the effect estimates for O and NO were minimal. Additional research should continue to explore these and the associations between outdoor air pollution and epilepsy and between noise pollution and seizures and epilepsy.

Review
The rising demand for food packaging has led to a growing interest in sustainable and eco-friendly food coatings. Carboxymethyl cellulose (CMC), being a versatile cellulose derivative produced from various lignocellulosic sources, has emerged in edible food coatings. This review evaluates the research trends on CMC production from empty fruit bunch (EFB) as a potential edible food coating material by systematic review approach. It explores sustainable pre-treatment for green cellulose and different CMC synthesis methods. The review compares CMC-based coatings to other materials, focusing on formulation processes, coating quality, safety, and commercial feasibility. The bibliometric analysis is performed to correlate food coating and CMC. As a result, the study discovered the rapid growth in research on edible food coatings made from CMC for various food industry applications. The green approach such as ozone pre-treatment appear as promising method for cellulose isolation from EFB to be used as raw material for CMC. The synthesis conditions of the treatment would affect the CMC characteristics and usage. Herein, utilizing CMC from cellulose EFB in coating formulation and on coated food shows different benefits. This review provides a road map for future research with potential to make important contributions to the food industry's long-term evolution.
