Of the enrolled study, 85.9% were asymptomatic and 14.1% were mild. Epidemiological data showed that the transmission speed of the Omicron variant was fast and the transmission range was wide, large-scale infections occurred in both rural and urban areas, and all age groups were susceptible to the Omicron variant. In addition, antipyretics and cough drugs were the two most used drugs, because 51.3% and 22.7% of patients had fever and cough, respectively, and 10.3% of patients took hypnotics. Furthermore, the proportion of patients with chronic diseases was low (13.9%), while the vaccination rate (71.2%) was relatively high. Based on the results, we found that most mild and asymptomatic cases did not need treatment, indicating that home isolation is correct and feasible.

By analyzing human data and conducting subsequent animal experiments, the researchers found that air pollutants PM2.5 leads to an influx of macrophages into the lung and triggers the release of interleukin-1β. This, in turn, induces a progenitor-like cell state within estimated glomerular filtration rate (EGFR) mutant lung alveolar type II epithelial cells, fueling tumorigenesis, and potentially exacerbating pre-existing cancerous mutations in normal tissues.</p><p>While the association between smoking and lung cancer risk is well-established, attention has increasingly turned towards understanding the carcinogenic factors in never-smokers.

The findings revealed a correlation between increased levels of PM2.5 and a higher incidence of lung cancer among the study participants. Later analysis of 407,509 individuals from the UK Biobank support these results, demonstrating significant increase in the projected incidence of lung cancer among those exposed to high levels of PM2.5. The researchers also conducted a 3-year follow-up study involving 228 Canadian lung cancer patients. The incidence of lung cancer was found to be significantly higher (73%) in those exposed to high levels of PM2.5 compared to those exposed to low levels (40%). Notably, this association was not observed in the Canadian cohort over a 20-year period, suggesting that 3 years of exposure to high levels of pollution may be sufficient to produce cancer.</p><p>Hill et al. further employed genetically engineered mice carrying EGFR mutations (EGFR^L858R) associated with human cancer to functionally investigate whether PM2.5 exposure promoted the development of lung adenocarcinoma.

The same experiments were performed on genetically engineered mice with Kras mutations, a common mutation in various lung tumors, yielding similar results.

Upon infection, antigenic determinants of the virus trigger massive production of proinflammatory/pyroptosis-associated proteins, resulting in cytokine storm, tissue damage, and multiorgan failure. Therefore, these proinflammatory/pyroptosis-associated mediators are promising therapeutic targets to combat COVID-19. Epicatechin gallate (ECG) is a polyphenol found in green tea. It has antioxidative and anti-inflammatory properties. Hence, in the present study, ECG was selected to explore its binding potential for inflammatory mediators such as interleukins, interferon-γ (IFNγ), and tumor necrosis factor-α (TNF-α), along with their native receptors. In addition, the interacting potential of ECG with pyroptosis-associated proteins, viz. caspases and BAX has also been investigated. Molecular docking analysis has revealed that ECG interacts with interleukins, IFNγ, TNF-α, cytokine receptors, caspase-1/4/11, and BAX with significant binding affinity. Several amino acid residues of these mediators were blocked by ECG through stable hydrogen bonds and hydrophobic contacts. ECG interacted with caspase-11, BAX, and TNF-R1 with better binding affinities.
