    Analysis of the relationship between tuberculosis-related mortality and nitrous oxide emission levels in the world with the environmental Kuznets curve method
    (2022) Torun, Serife; Yilmaz, Kadir; Ozkaya, Sevket; Yosunkaya, Sebnem; Akcay, Sule; 36326361
    Background/aim: It was aimed to analyze the relationship between tuberculosis-related mortality and nitrous oxide emission levels in the world with the Environmental Kuznets Curve (EKC) Method. Materials and methods: WHO ICD-10 mortality list data and the World Bank Country Data (WBCD) were used between 1997 and 2017 for 12 countries. Cubic regression analysis was used for EKC Analysis. Results: The difference between male and female deaths between 1996 and 1998 has increased sharply since 1999. Male deaths consistently occurred significantly more than female deaths. There was a significant and negative correlation between Nitrous oxide emissions (% change from 1990) and tuberculosis-related deaths, whereas there were significant and positive correlations between Nitrous oxide emissions in the energy sector (% of total) and tuberculosis-related deaths (p < 0.01). EKC analysis results showed that there is a U shaped between tuberculosis-related mortality and nitrous oxide emission levels in the world. Conclusion: Research results show that the relationship between nitrous oxide change and mortality is negative in the short term and positive in the long term. Therefore, although nitrous oxide gases cause respiratory diseases and mortality, it may be possible to transform a harmful environmental factor into a positive by developing devices or methods that will convert these gases into free radicals.

    The COVID-19 pandemic has brought countries' health services into sharp focus. It was drawn to our group's attention that healthcare workers (HCWs) had a lower mortality rate against higher COVID-19 incidence compared to the general population in Turkey. Since risk of exposure to tuberculosis bacillus among healthcare workers are higher than the population, we aimed to investigate if there is a relationship between BCG and Mycobacterium tuberculosis exposure history with COVID-19 severity in infected HCWs. This study was conducted with 465 infected HCWs from thirty-three hospitals to assess the relationship between COVID-19 severity (according to their hospitalization status and the presence of radiological pneumonia) and BCG and Mycobacterium tuberculosis exposure history. HCWs who required hospital admission had significantly higher rates of chronic diseases, radiological pneumonia, and longer working hours in the clinics. Higher rates of history of contact and care to tuberculosis patients, history of tuberculosis, and BCG vaccine were observed in hospitalized HCWs. HCWs who had radiological pneumonia had a significantly increased ratio of history of care to tuberculosis patients and a higher family history of tuberculosis. The findings from our study suggest that the lower mortality rate despite the more severe disease course seen in infected HCWs might be due to frequent exposure to tuberculosis bacillus and the mortality-reducing effects of the BCG vaccine.
