“…Our cohort consisted of mostly middle aged Asians with higher socioeconomic and education levels and urban habitation with the highest annual PM concentrations in the world. Thus, these characteristics can contribute to more increase in the amount of mobilized iron especially in men than women in our cohort [8,[21][22][23][24][25][26]. The large difference in serum ferritin level between men and women can contribute to much higher lifetime iron stores in men than in women.…”

Decreased lung function is associated with elevated ferritin but not iron or transferrin saturation in 42,927 healthy Korean men: A cross-sectional study

Objectives Though elevated ferritin level and decreased lung function both predispose people to cardio-metabolic disease, few reports have investigated the association between them. Furthermore, it remains unclear whether the association reflects a change in iron stores or an epiphenomenon reflecting metabolic stress. Therefore, we looked for possible associations between ferritin, iron, and transferrin saturation (TSAT) and lung function to clarify the role of iron-related parameters in healthy men. Methods We conducted a cohort study of 42,927 healthy Korean men (mean age: 38.6 years). Percent predicted forced expiratory volume in one second (FEV1%) and forced vital capacity (FVC%) were categorized into quartiles. Adjusted odds ratios (aORs) and 95% confidence intervals (using the highest quartile as reference) were calculated for hyperferritinemia, high iron, and high TSAT after controlling for potential confounders. Results The median ferritin level was 199.8 (141.5-275.6) ng/mL. The prevalence of hyperferritinemia (defined as >300 ng/mL) was 19.3%. Subjects with hyperferritinemia had lower FEV1% and FVC% than those with normal ferritin level with a slight difference, but those were statistically significant (99.22% vs.99.61% for FEV1%, p = 0.015 and 98.43% vs. 98.87% for

“…In the month of December 2019 and January 2020, the overall pollution level is found to be high in all the highly urbanized and industrialized nations like India, China, Bangladesh, West African countries, South American Countries, and some of the western European countries. Earlier pollution reports and studies have exhibited the same situation (Tilt, 2019;North et al, 2019;Li et al, 2019). But after implementation of lockdown in different countries to stop COVID 19, the different parts of the world have experienced an improvement in air quality (Dutheil et al, 2020;Mahato et al, 2020;Muhammad et al, 2020 were under hazardous to unhealthy AQS category in the pre-lockdown period, and all these countries have shifted to good to very good AQS category during lockdown (February-March, 2020).…”

COVID-19 outbreak across the world has invited forced lockdown conditions, which causes a huge economic landslide. But it has brought an opportunity for restoring the environment of its own which may cause ecosystem well-being. Focusing on the second issue, the present work has intended to explore the streams of air quality change based on some quality components and develop a multi-date air quality state (AQS) model for the world in consequence of emergency lockdown. It is very clear from the result that amid lockdown aerosol optical depth (AOD), sulfur dioxide (SO2), ozone, carbon monoxide (CO), particulate matter (PM2.5), and black carbon (BC) concentration level have been significantly reduced in fully lockdown countries. AQS is considerably improved amid lockdown. Hotspots of COVID-19 were under unhealthy, very unhealthy air quality class in pre lockdown condition, but amid lockdown, these countries have been shifted to good and moderate healthy air quality classes

“…Air pollution (outdoor and indoor) is a grave risk to human health that affects nearly everyone in the world and nearly every organ in the body (64). In addition to public health measures that encourage avoidance, compelling epidemiological studies and mechanistic studies will add to the body of evidence to persuade global policy change, particularly for vulnerable populations (47). The impact of air pollution goes far beyond the lung (COPD, lung cancer, poor lung development), additionally linked to cardiovascular deaths, stroke, bladder cancer, childhood leukemia, risk of dementia, diabetes mellitus prevalence, allergic rhinitis, allergic sensitization, autoimmunity, osteoporosis and fractures, conjunctivitis, dry eye disease, blepharitis, inflammatory bowel disease, increased intravascular coagulation, decreased glomerular filtration rate, atopic and urticarial skin disease, acne, and skin aging (62,63).…”
