Abstract Three and a half years after the pandemic outbreak, now that WHO has formally declared emergency is over, COVID-19 still significant global issue. Here, we focus on recent developments in genetic genomic research COVID-19, give an outlook state-of-the-art therapeutical approaches, as gradually transitioning to endemic situation. The sequencing characterization of rare alleles different populations made it possible identify numerous genes affect either susceptibility or severity disease. These findings provide beginning new avenues pan-ethnic therapeutic well potential screening protocols. causative virus, SARS-CoV-2, spotlight, but novel threatening virus could appear anywhere at any time. Therefore, continued vigilance further warranted. We also note emphatically prevent future pandemics other world-wide health crises, imperative capitalize what have learnt from COVID-19: specifically, regarding its origins, world’s response, insufficient preparedness. This requires unprecedented international collaboration timely data sharing for coordination effective response rapid implementation containment measures.

A pragmatic framework for the application of new approach methodologies in one health toxicological risk assessment

Toxicological Sciences, Journal Year: 2023, Volume and Issue: 192(2), P. 155 - 177

Published: Feb. 14, 2023

Globally, industries and regulatory authorities are faced with an urgent need to assess the potential adverse effects of chemicals more efficiently by embracing new approach methodologies (NAMs). NAMs include cell tissue methods (in vitro), structure-based/toxicokinetic models silico), that toxicant interactions biological macromolecules chemico), alternative models. Increasing knowledge on chemical toxicokinetics (what body does chemicals) toxicodynamics do body) obtained from in silico vitro systems continues provide opportunities for modernizing risk assessments. However, directly leveraging data derivation human health-based reference values has not received acceptance due uncertainties extrapolating NAM results populations, including metabolism, complex pathways, multiple exposures, interindividual susceptibility vulnerable populations. The objective this article is a standardized pragmatic framework applies integrated approaches focus quantitative vivo extrapolation (QIVIVE) extrapolate cellular exposures equivalent doses which can be derived. proposed intends systematically account complexities interpretation support sound health safety decisions diverse industrial sectors (food systems, cosmetics, chemicals, pharmaceuticals etc.).

Mechanisms Leading to Gut Dysbiosis in COVID-19: Current Evidence and Uncertainties Based on Adverse Outcome Pathways

Journal of Clinical Medicine, Journal Year: 2022, Volume and Issue: 11(18), P. 5400 - 5400

Published: Sept. 14, 2022

Alteration in gut microbiota has been associated with COVID-19. However, the underlying mechanisms remain poorly understood. Here, we outlined three potential interconnected mechanistic pathways leading to dysbiosis as an adverse outcome following SARS-CoV-2 presence gastrointestinal tract. Evidence from literature and current uncertainties are reported for each step of different pathways. One pathway investigates evidence that intestinal infection by inducing inflammation alters microbiota. Another links binding viral S protein angiotensin-converting enzyme 2 (ACE2) dysregulation this receptor, essential homeostasis—notably amino acid metabolism—leading dysbiosis. Additionally, could induce infecting bacteria. Assessing within Adverse Outcome Pathway framework justifies confidence proposed support disease management permits identification inconsistencies knowledge gaps orient further research.

A curated gene and biological system annotation of adverse outcome pathways related to human health

Scientific Data, Journal Year: 2023, Volume and Issue: 10(1)

Published: June 24, 2023

Adverse outcome pathways (AOPs) are emerging as a central framework in modern toxicology and other fields biomedicine. They serve an extension of pathway-based concepts by depicting biological mechanisms causally linked sequences key events (KEs) from molecular initiating event (MIE) to adverse outcome. AOPs guide the use development new approach methodologies (NAMs) aimed at reducing animal experimentation. While model systemic various levels organisation, toxicogenomics provides means study chemical exposures. Systematic integration these two would improve application AOP-based knowledge while also supporting interpretation complex omics data. Hence, we established this link through rigorous curation annotations for KEs human relevant AOPs. We further expanded consolidated context KEs. These curated pave way embed data interpretation, facilitating emergence

Peculiar weather patterns effects on air pollution and COVID-19 spread in Tokyo metropolis

Environmental Research, Journal Year: 2023, Volume and Issue: 228, P. 115907 - 115907

Published: April 18, 2023

As a pandemic hotspot in Japan, between March 1, 2020–October 2022, Tokyo metropolis experienced seven COVID-19 waves. Motivated by the high rate of incidence and mortality during seventh wave, environmental/health challenges we conducted time-series analysis to investigate long-term interaction air quality climate variability with viral Tokyo. Through daily time series geospatial observational pollution/climate data, death cases, this study compared environmental conditions multiwaves. In spite five State Emergency (SOEs) restrictions associated pandemic, (2020–2022) period recorded low improvements relative (2015–2019) average annual values, namely: Aerosol Optical Depth increased 9.13% 2020 year, declined 6.64% 2021, 12.03% 2022; particulate matter PM2.5 PM10 decreased 2020, 2022 years 10.22%, 62.26%, 0.39%, respectively 4.42%, 3.95%, 5.76%. For (2021–2022) ratio PM2.5/PM10 was (0.319 ± 0.1640), showing higher contribution aerosol loading traffic-related coarse particles comparison fine particles. The highest rates cases wave (1 July 2022–1 October 2022) may be attributed accumulation near ground levels pollutants pathogens due to: 1) peculiar persistent atmospheric anticyclonic circulation strong positive anomalies geopotential height at 500 hPa; 2) lower Planetary Boundary Layer (PBL) heights; 3) maximum temperature land surface prolonged heat waves (HWs) summer 4) no imposed restrictions. Such findings can guide public decision-makers design proper strategies curb pandemics under stable weather HWs large metropolitan areas.

Mechanistic Understanding of the Olfactory Neuroepithelium Involvement Leading to Short-Term Anosmia in COVID-19 Using the Adverse Outcome Pathway Framework

Cells, Journal Year: 2022, Volume and Issue: 11(19), P. 3027 - 3027

Published: Sept. 27, 2022

Loss of the sense smell (anosmia) has been included as a COVID-19 symptom by World Health Organization. The majority patients recover within few weeks postinfection (short-term anosmia), while others report persistent anosmia. Several studies have investigated mechanisms leading to anosmia in COVID-19; however, evidence is scattered, and remain poorly understood. Based on comprehensive review literature, we aim here evaluate current knowledge uncertainties regarding short-term following SARS-CoV-2 infection. We applied an adverse outcome pathway (AOP) framework, well established toxicology, propose sequence measurable key events (KEs) COVID-19. Those KEs are (1) Spike proteins binding ACE-2 expressed sustentacular (SUS) cells olfactory epithelium (OE); (2) viral entry into SUS cells; (3) replication (4) cell death; (5) damage sensory neurons (OE). This AOP-aligned approach allows for identification gaps where more research should be conducted therapeutic intervention could act. Finally, this AOP gives frame explain several disease features can linked specific factors that lead interindividual differences response
