The oral cavity also serves as a reservoir for SARS-CoV-2 because the virus is present in and replicates in oral secretions (saliva and gingival crevicular fluid), oral tissues (salivary gland and periodontal tissue), and oral microenvironments (gingival sulcus and periodontal pocket). Despite a high risk of SARS-CoV-2 infection, the prevalence of COVID-19 in dentists, dental hygienists, dental assistants, and their patients was similar to that in the general population even during the pandemic. We propose that eugenol, which is responsible for the ambient odor specific to dental offices, could contribute to prevention of COVID-19 in dental settings. Eugenol is not only released from dental materials (filling, cement, and sealer) but is also aerosolized by dental procedures (grinding, polishing, and restoration). Such eugenol has been suggested to possess the potential to inhibit the infectivity and replication of SARS-CoV-2, the entry of SARS-CoV-2 into human cells by binding specifically to the viral spike protein, and the protease indispensable for SARS-CoV-2 replication. It has been shown that aerosolized eugenol acts on airborne viruses to reduce their loads. This review highlights a hypothesis that the environment of dental offices impregnated with eugenol suppresses SARS-CoV-2 airborne transmission and SARS-CoV-2 contagion between dental professionals and patients, preventing COVID-19 in dental practice. Anti-COVID-19 eugenol might give insights into the safe delivery of dental treatment and oral care in the COVID-19 era.</p>","PeriodicalId":18455,"journal":{"name":"Medical Principles and Practice","volume":" ","pages":"83-89"},"PeriodicalIF":2.9,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11095613/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139040238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Disruptions in myelin integrity are associated with numerous neurological disorders, including multiple sclerosis. In the central nervous system (CNS), myelin is formed by oligodendrocytes. Remyelination refers to the re-formation of the damaged myelin sheath by newly formed oligodendrocytes. Steroids have gained attention for their potential modulatory effects on myelin in both health and disease. Steroids are traditionally associated with endocrine functions, but their local synthesis within the nervous system has generated significant interest. The term \"neuroactive steroids\" refers to steroids that can act on cells of the nervous system. In the healthy state, neuroactive steroids promote myelin formation, maintenance, and repair by enhancing oligodendrocyte differentiation and maturation. In pathological conditions, such as demyelination injury, multiple neuroactive steroids have shown promise in promoting remyelination. Understanding the effects of neuroactive steroids on myelin could lead to novel therapeutic approaches for demyelinating diseases and neurodegenerative disorders. This review highlights the potential therapeutic significance of neuroactive steroids in myelin-related health and diseases. We review the synthesis of steroids by neurons and glial cells and discuss the roles of neuroactive steroids on myelin structure and function in health and disease.

The aim of this study was to investigate the prevalence of early-onset type 1 diabetes (T1D) in Kuwait as well as describe their baseline clinical, biochemical, and immunological characteristics.</p><p><strong>Methods: </strong>Medical records of children newly diagnosed with T1D and registered in the Childhood-Onset Diabetes electronic Registry (CODeR) in Kuwait between 2017 and 2022 were reviewed. Early-onset T1D was defined as diagnosis at age younger than 6 years.</p><p><strong>Results: </strong>2,051 children were registered with new-onset T1D between 2017 and 2022, of which 657 (32.0%) were diagnosed at early onset. There has been a trend of slight increase in the percentage of early-onset T1D after 2020 (15.2%) with a prevalence of 18.4% and 20.2% in 2021 and 2022, respectively (p = 0.056). Age at onset was inversely related to admission to the pediatric intensive care unit (OR = 0.90, 95% CI: 0.85, 0.95, p < 0.0001) and was directly related to positive celiac autoimmunity (p = 0.022), higher hemoglobin A1C (p < 0.0001), and C-peptide levels (p < 0.0001). However, age at onset of T1D was inversely related to the higher vitamin D levels (p < 0.0001).</p><p><strong>Conclusion: </strong>These findings reinforce the need for increased attention to be given to study the development of T1D in children of younger age. This in turn will support special management and prevention measures targeted toward this vulnerable age group.</p>","PeriodicalId":18455,"journal":{"name":"Medical Principles and Practice","volume":" ","pages":"555-561"},"PeriodicalIF":2.9,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11631037/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141889745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
