Introduction: The COVID-19 pandemic has increased the magnitude of mental illnesses such as depression, not only in the general population, but also in healthcare personnel. However, in Peru the prevalence, and the associated factors for developing depression in healthcare personnel, are not known. The objective was to determine the prevalence and identify the factors associated with depression in healthcare personnel, in the context of the SARS-CoV-2 pandemic. Methods: An analytical cross-sectional study was carried out from May to September, 2020 in healthcare establishments. A sample of 136 health workers were included and a survey was applied to collect the data. Depression as a dependent variable was measured using the Zung self-report scale. To identify the associated factors, the bivariate and multivariate analysis was performed by logistic regression with STATA v 14. Results: The prevalence of depression was 8.8% (95%CI, 4.64-14.90). Having a family member or friend who had died from COVID-19 was associated with depression (OR = 6.78; 95%CI, 1.39-32.90; P = 0.017). Whereas the use of personal protective equipment was found to be a protective factor against developing depression (OR = 0.03; 95%CI, 0.004-0.32; P = 0.003). Conclusions: Approximately 1 in 10 healthcare professionals and technicians developed depression during the COVID-19 pandemic in this study. In addition, having relatives or friends who had died from COVID-19 was negatively associated with depression and use of personal protective equipment was identified as a protective factor. / Revisión por pares

>Magister Scientiae - MSc / Insect-derived baculoviruses have been used extensively as a safe and versatile research model for transgenic protein expression. Preclinical studies have revealed the promising potential of Baculoviruses as a delivery vector for a variety of therapeutic applications, including vaccination, tissue engineering and cancer treatments. Coronaviruses are enveloped viruses containing linear, non-segmented ribonucleic acid. Human coronavirus NL63 was first discovered in the Netherlands in January 2004, where a 7-month-old girl presented with an acute respiratory tract infection that was later established to predominantly infect infants, the elderly and immunocompromised individuals. In addition to the known non-structural and structural proteins of coronaviruses, an accessory protein known as open reading frame 3 which is conserved in the Coronaviridae family has not been extensively researched. Open reading frame 3 encodes a putative membrane-bound protein. This study cloned the open reading frame 3 viral gene of 741 base pairs into the baculovirus expression construct via competent bacterial cell lines. Open reading frame 3-Baculovirus particles were generated in Spodoptera frugiperda insect cells. Recombinant cells containing the viral protein gene were used to infect healthy Spodoptera frugiperda 9 cells at varying ratios of multiplicity of infection over a fixed time-course. The open reading frame 3 viral protein was not detected by quantification methods at a molecular weight of 26 kilo Dalton, due to polyclonal antibody degradation.
