Systematic literature search identified 46 studies and all reported <em>BRCA1</em>/2 variants from each study were re-interpreted using ClinVar and <em>BRCA</em> Exchange to determine pathogenicity. In both cohorts, the median age of BC diagnosis was < 40 years. A total of 159 <em>BRCA1</em> and 100 <em>BRCA2</em> PVs were reported in 772 index South Asian and Middle Eastern BC cases. Only 10 <em>BRCA1/2</em> PVs (6 %) overlapped between the two cohorts, while 141 <em>BRCA1</em> and 98 <em>BRCA2</em> PVs were exclusive to either SAARC or GCC cohorts. <em>BRCA1</em> c.68_69del was the most recurrent PV (n = 111). Overall, <em>BRCA1</em> PVs were prevalent in early-onset (83 %), triple-negative (95 %), and familial BC disease (80 %).

Our findings highlight the necessity for population-specific genetic testing and indicate a clear regional genetic propensity in <em>BRCA</em> gene.

Interleukin (IL) 1β, IL-6, IL-8, IL-10, tumor necrosis factor alpha (TNFα), C reactive protein (CRP)) were examined in firefighters following exposure to typical firefighting duties including structural and wildland fires. Experimental studies without exposure to combustion emissions were also reviewed to examine the specific contribution of heat exposure, physical exertion, cognitive load and restricted sleep to inflammation in firefighters. For chronic inflammation, the strongest evidence existed for elevated circulating IL-6 (n = 5 studies), followed by elevated IL-1β (n = 3), CRP (n = 3) and IL-8 (n = 2). Acute elevations in IL-6 (n = 8 studies), IL-8 (n = 7) and IL-1β (n=4) were also evident in firefighters in the hours and days following exposure to structural and wildland fires. Experimental studies provided evidence that physical exercise and heat contribute to acute elevations in IL-6 (n = 6) and TNFα (n = 3). In summary, the data reviewed provide strong support that typical firefighting duties can induce both acute and chronic inflammation. More work is needed to determine the prevalence of inflammation in firefighters and to identify mitigating strategies to lower the risk of firefighters developing inflammatory related-chronic disease.</div></div>","PeriodicalId":49789,"journal":{"name":"Mutation Research-Reviews in Mutation Research","volume":"796 ","pages":"Article 108569"},"PeriodicalIF":4.2,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145566224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This systematic review aimed to consolidate existing knowledge on the genotoxic potential of emerging aquatic pollutants. A comprehensive search was conducted across major databases, encompassing articles published from 2001 to 2022. The review primarily focused on research articles that evaluated genotoxicity in environmental samples containing emerging pollutants, as well as in vitro studies using various concentrations of these substances. Fourteen articles were included in the review, with pharmaceutical compounds, personal care products, disinfection byproducts, and industrial chemicals being the most extensively investigated classes. Other notable pollutants included metals, cyanotoxins, antiseptics, pesticides, and caffeine. All these pollutants classes were found to cause DNA damage, either in vitro at specific concentrations or in complex environmental mixtures. The comet assay was the most frequently used method, owing to its sensitivity and practicality in assessing DNA damage. For some pollutants, different responses were observed when comparing in vitro and in vivo studies, emphasizing the need for studies employing both approaches. However, the limited number of available articles underscores the necessity for further research on the genotoxic potential of emerging pollutants. More research is required to clarify mutagenicity, DNA repair kinetics, and cumulative effects of pollutants, which are critical for shaping policies and ensuring safe water quality.

PAX inhibits viral replication while MOV induces viral replication errors that are expected to lead to viral inactivation.
