Dental workers in front-line of COVID-19: an in silico evaluation targeting their prevention.

ABSTRACT:

Objective

SARS-CoV-2 has high human-human transmission rate. The aerosols and saliva droplets are the main contamination source. Thus, it is crucial to point out that dental practitioners become a high-risk group of contagion by SARS-CoV-2. Based on this, protocols have been recommended to avoid cross-contamination during dental care; however, appropriate evidence has not yet been established. Our study sought to make a screening, by in silico analysis, of the potential of mouth rinses used in dental practices to prevent the dental workers' contamination by SARS-CoV-2.

Methodology

Multiple sequence comparisons and construction of the phylogenetic tree were conducted using the FASTA code. Therefore, molecular docking investigation between SARS-CoV-2 proteins (Main Protease, Spike Glycoprotein, Non-structure Protein, and Papain-like Protease) and molecules used in dental practices (chlorhexidine digluconate, hydrogen peroxide, cetylpyridinium chloride, povidone-iodine, gallic acid, β-cyclodextrin, catechin, and quercetin) was performed using AutoDock Vina. Moreover, 2D interactions of the complex protein-ligand structure were analyzed by Ligplot+.

Results

The obtained results showed a remarkable affinity between SARS-CoV-2 proteins and all tested compounds. The chlorhexidine digluconate, catechin, and quercetin presented a higher affinity with SARS-CoV-2.

Conclusions

The overall results allowed us to suggest that chlorhexidine is the most suitable active compound in reducing the SARS-CoV-2 salivary load due to its better binding energy. However, in vivo studies should be conducted to confirm their clinical use.

Project description:ObjectivesWorkplace violence (WPV) against healthcare workers (HCWs) is a global issue. Our research aimed to elucidate the status and associated factors of WPV among front-line/non-front-line HCWs during the COVID-19 pandemic.DesignThis cross-sectional study was conducted among HCWs in Hangzhou City through multistage sampling from December 2020 to January 2021.ParticipantsThis study included 14 909 valid samples (N=3748 front-line HCWs and N=11 161 non-front-line HCWs).Primary and secondary outcome measuresWe assessed the WPV status by Chinese version of WPV questionnaire. Binary logistic regression model was established to examine the associated factors of front-line/non-front-line HCWs experiencing WPV.ResultsThe total WPV prevalence equalled 37.25% for front-line HCWs and 27.73% for non-front-line HCWs. Among front-line HCWs, females were less likely to experience WPV (OR 0.837, 95% CI 0.710 to 0.988), while individuals who were undergraduate (OR 1.251, 95% CI 1.061 to 1.541) and had higher professional title (intermediate: OR 1.475, 95% CI 1.227 to 1.772; advanced: OR 1.693, 95% CI 1.294 to 2.216) were more likely to suffer from WPV; for non-front-line HCWs, individuals who aged over 50 years old (OR 0.721, 95% CI 0.563 to 0.969), had worked between 10 and 19 years (OR 0.847, 95% CI 0.749 to 0.958) and worked in the non-graded hospital (OR 0.714, 95% CI 0.614 to 0.832) had less chance to experience WPV, while individuals who had higher educational level (undergraduate: OR 1.323, 95% CI 1.179 to 1.484; ≥graduate: OR 1.519, 95% CI 1.217 to 1.895), were nurse (OR 1.142, 95% CI 1.031 to 1.265), and had higher professional title (intermediate: OR 1.458, 95% CI 1.297 to 638; advanced: OR 1.928, 95% CI 1.607 to 2.313) were more inclined to suffer from WPV (p all<0.05).ConclusionsThis study indicates that the prevalence of WPV among front-line HCWs is significantly higher than among non-front-line HCWs. Policy-makers should prioritise COVID-19 front-line HCWs, especially those with high educational levels and professional titles.

Project description:ObjectivesThis study aimed to explore the lived experience of Jordanian front-line healthcare workers (FHCWs), including their experienced challenges and adaptations amid the COVID-19 pandemic.DesignA phenomenological qualitative design was used to highlight the experiences of a sample Jordanian FHCWs during the COVID-19 pandemic. Qualitative interviews were conducted using a semistructured guide with open-ended questions, audiotaped and then transcribed verbatim. Thematic analysis of the transcribed narratives was conducted using an open coding line by line to develop themes and related subthemes.SettingMobile COVID-19 testing and contact tracing units during an active surge of cases in Jordan between May and September 2020.ParticipantsParticipants were recruited using purposive sampling method and consisted of 15 FHCWs (2 physicians, 10 nurses, 2 paramedics and 1 laboratory technician) who have worked in testing and contact tracing teams in the community and have dealt with suspected or confirmed cases of COVID-19 infection.ResultsParticipant narratives were classified into two main overarching themes; challenges and adaptation themes. The challenges theme was exhibited as follows: (1) an excruciating encounter with an invisible enemy, (2) distorted knowledge about COVID-19 and (3) organisational and administrative challenges. The adaptation theme was exhibited as follows: (1) seeking relevant knowledge about the disease and (2) seeking more connectedness.ConclusionsThe COVID-19 pandemic exerted many challenges for FHCWs at multiple levels; intrapersonal and interpersonal, organisational and societal levels. Nevertheless, a number of adaptation strategies within these levels have been reported. This study helps to provide the base on which healthcare officials and public health personnel can formulate preparedness plans that tackle challenges faced by front-line workers, which ultimately enhance the resilience of healthcare systems to withstand future pandemics.
