RESUMO
La pandemia por COVID-19 expuso a los trabajadores de salud a una enorme exigencia y presión en su labor cotidiana. Objetivo: Evaluar el nivel de depresión, ansiedad y estrés en trabajadores de salud durante la pandemia por COVID-19 y su asociación con características personales, laborales,sentimientos, experiencias y conductas relacionadas a la pandemia. Materiales y métodos: Estudio analítico de corte transversal. Durante el mes de junio del 2020 se enviaron formularios vía e-mail y redes sociales a trabajadores de la salud del sector público de La Plata y Gran La Plata. Se evaluó el nivel de depresión, ansiedad, y estrés mediante el cuestionario DASS-21. Se relevaron variables personales, laborales, sentimientos, experiencias y conductas vinculados a la pandemia. Se analizó la asociación entre las características de los trabajadores y la presencia de síntomas psicológicos mencionados. Resultados: Participaron 515 trabajadores, 41 años (33;50), 83,3% femenino. El síntoma psicológico más frecuente fue el estrés (58,2 %), seguido por ansiedad (33,1%) y depresión (24,7%). Se hallaron mayores chances de presentar estos síntomas en trabajadores que percibieron sentimientos, experiencias y conductas negativas vinculados a la pandemia. Los trabajadores de enfermería y administración, y aquellos que convivían con personas de riesgo tuvieron mayores chances de presentar ansiedad. Conclusión: Los trabajadores de salud de La Plata y Gran La Plata presentaron diversos grados de depresión, ansiedad y estrés que se asocian a sentimientos negativos relacionados con la pandemia
The COVID-19 pandemic exposed health workers to enormous demands and pressure in their daily work. Objective: To evaluate the level of anxiety, depression and stress in health workers during the COVID-19 pandemic and its association with personal and work characteristics, feelings, experiences, and behaviors related to the pandemic. Materials and methods: Cross-sectional analytical study. During the month of June 2020, forms were sent via e-mail and social networks to health workers in the public sector of La Plata and Gran La Plata. The level of depression, anxiety, and stress was evaluated using the DASS-21 questionnaire. Personal and work variables, feelings, experiences and behaviors linked to the pandemic were surveyed. The association between the characteristics of the workers and the presence of the aforementioned psychological symptoms was analyzed. Results: 515 workers participated, 41 years old (33;50), 83.3% female. The most frequent psychological symptom was stress (58.2%), followed by anxiety (33.1%) and depression (24.7%). Greater chances of presenting these symptoms were found in workers who perceived negative feelings, experiences and behaviors linked to the pandemic. Nursing and administration workers, and those who lived with people at risk had a higher chance of presenting anxiety. Conclusion: Health workers from La Plata and Gran La Plata presented varying degrees of depression, anxiety, and stress that are associated with negative feelings related to the pandemic

In the present study, we analyzed DNA damage induced by phycocyanin (PHY) in the presence of visible light (VL) using a set of repair endonucleases purified from Escherichia coli. We demonstrated that the profile of DNA damage induced by PHY is clearly different from that induced by molecules that exert deleterious effects on DNA involving solely singlet oxygen as reactive species. Most of PHY-induced lesions are single strand breaks and, to a lesser extent, base oxidized sites, which are recognized by Nth, Nfo and Fpg enzymes. High pressure liquid chromatography coupled to electrochemical detection revealed that PHY photosensitization did not induce 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodGuo) at detectable levels. DNA repair after PHY photosensitization was also investigated. Plasmid DNA damaged by PHY photosensitization was used to transform a series of Saccharomyces cerevisiae DNA repair mutants. The results revealed that plasmid survival was greatly reduced in rad14 mutants, while the ogg1 mutation did not modify the plasmid survival when compared to that in the wild type. Furthermore, plasmid survival in the ogg1 rad14 double mutant was not different from that in the rad14 single mutant. The results reported here indicate that lethal lesions induced by PHY plus VL are repaired differently by prokaryotic and eukaryotic cells. Morever, nucleotide excision repair seems to play a major role in the recognition and repair of these lesions in Saccharomyces cerevisiae
