Cotidiano e desafios da enfermagem em unidades hospitalares COVID-19: perspectiva dos profissionais / Daily life and challenges of nursing in COVID-19 hospital units: professionals' perspective

Introdução: O trabalho de enfermagem em unidades hospitalares COVID-19 é complexo, desafiador e repleto de elementos cuja compreensão é importante para o campo da Gestão e Saúde no Trabalho. Objetivo: Compreender o cotidiano e os desafios de trabalhadores de enfermagem na linha de frente do enfrentamento à pandemia em unidades hospitalares COVID-19. Materiais e Métodos: Estudo qualitativo desenvolvido com 35 trabalhadores de enfermagem em unidades COVID-19 de sete hospitais do Sul do Brasil, por meio de entrevistas semiestruturadas. O software NVivo auxiliou no tratamento dos dados a partir da análise temática de conteúdo. Resultados: Da análise dos dados emergiram duas categorias analíticas: Desafios do cotidiano de enfermagem nas unidades COVID-19: complexidade e demandas da assistência; e Desafios de ser um trabalhador de enfermagem da linha de frente: desdobramentos no bem-estar profissional e na vida pessoal. Discussão: Pode-se considerar que a complexidade e intensificação do trabalho na linha de frente causou impactos que podem conduzir os trabalhadores de enfermagem ao adoecimento. São importantes ações de promoção à visibilidade profissional junto à sociedade para desmistificar a imagem romantizada sobre a profissão e problematizar a importância da enfermagem no enfrentamento da pandemia e os impactos sofridos por estes trabalhadores. Conclusão: Trabalhadores de enfermagem de unidades COVID-19 vivenciam desafios complexos, com repercussões em sua experiência laboral e em sua vida.

Introduction: The nursing work in COVID-19 hospital units is complex, challenging, and full of elements whose understanding is important for the field of Management and Health at Work. Objective: To understand the daily life and challenges of nursing workers in the front line of confronting the pandemic in COVID-19 hospital units. Materials and Methods: Qualitative study developed with 35 nursing workers in COVID-19 units from seven hospitals in southern Brazil, through semi-structured interviews. The NVivo software helped in the data treatment from the thematic content analysis. Results: Two analytical categories emerged from data analysis: Challenges of nursing daily life in COVID-19 units: complexity and demands of assistance; and Challenges of being a frontline nursing worker: unfolding in professional well-being and personal life. Discussion: It can be considered that the complexity and intensification of frontline work caused impacts that can lead nursing workers to illness. Actions to promote professional visibility in society are important, to demystify the romanticized image about the profession, and to problematize the importance of nursing in facing the pandemic and the impacts suffered by these workers. Conclusion: Nursing workers in COVID-19 units experience complex challenges, with repercussions on their work experience and their lives.

Introducción: El trabajo de enfermería en las unidades hospitalarias COVID-19 es complejo, desafiante y lleno de elementos cuya comprensión es importante para el campo de la Gestión y Salud Ocupacional. Objetivo: comprender el cotidiano y los desafíos de los trabajadores de enfermería en la primera línea de enfrentamiento a la pandemia en las unidades hospitalarias de la COVID-19. Materiales y Métodos: estudio cualitativo desarrollado con 35 trabajadores de enfermería en unidades de COVID-19 de siete hospitales del sur de Brasil, a través de entrevistas semiestructuradas. El software NVivo ayudó en el procesamiento de datos basado en el análisis de contenido temático. Resultados: del análisis de los datos surgieron dos categorías analíticas: Desafíos cotidianos de la enfermería en las unidades de COVID-19: complejidad y demandas asistenciales; y Desafíos de ser un trabajador de enfermería de primera línea: desarrollos en el bienestar profesional y personal. Discusión: se puede considerar que la complejidad e intensificación del trabajo en primera línea provocó impactos que podrían llevar a los trabajadores de enfermería a la enfermedad. Las acciones de promoción de la visibilidad profesional en la sociedad son importantes para desmitificar la imagen romantizada de la profesión y discutir la importancia de la enfermería en el enfrentamiento de la pandemia y los impactos sufridos por estos trabajadores. Conclusión: los trabajadores de enfermería de las unidades de COVID-19 viven desafíos complejos, con repercusiones en su experiencia laboral y en su vida.

Dietary interventions in mice affect oxidative stress and gene expression of the Prlr and Esr1 in the adipose tissue and hypothalamus of dams and their offspring.

Maternal diet is key to the progeny's health since it may impact on the offspring's adult life. In this study, mice dams received standard (CONT), restrictive (RD), or hypercaloric (HD) diets during mating, pregnancy, and lactation. Male offspring of each group of dams also received these diets: CONT, RD, HD. Aiming to evaluate the oxidative stress in the adipose tissue, reactive oxygen species (ROS) production, catalase (CAT), and superoxide dismutase (SOD) activities were analyzed in dams and offspring. In the adipose tissue and hypothalamus, gene expression of prolactin (Prlr) and estrogen alpha (Esr1) receptors was performed in dams and offspring. Protein expression of Stat5 was evaluated in the adipose tissue of the offspring from RD-fed dams. HD-fed dams increased triglycerides and leptin serum concentrations, and decreased SOD activity in the adipose tissue. In the offspring's adipose tissue, we observed a maternal diet effect caused by HD, with increased ROS production and SOD and CAT activities. Gene expression of Prlr and Esr1 in the offspring's adipose tissue was decreased due to maternal RD. Mice from HD-fed dams showed higher Stat5 expression compared to the offspring from CONT and RD dams in the adipose tissue. In the hypothalamus, we found decreased expression of Prlr in RD and HD dams, compared to CONT; and a maternal diet effect on Prlr and Esr1 gene expression in the offspring. In conclusion, we can affirm that maternal nutrition impacts the redox state and influences the gene expression of Prlr and Esr1, which are involved in energy metabolism, both peripherally and centrally in the adult life of the female offspring.

Immediate analgesic effect of two modes of short-wave diathermy application in chronic low back pain: study protocol for a randomized controlled trial.

The aim of this study is to evaluate and compare the immediate analgesic effects of two applications of short-wave diathermy (SWD) in individuals with chronic low back pain. Randomized, controlled, double-blind clinical trial. A total of 159 participants with chronic low back pain will be randomized in three groups: pulsed mode SWD, continuous mode SWD and placebo. SWD will be applied only once for 30 min. The primary outcomes: intensity and quality of pain. Secondary outcomes: depression and anxiety; perception of global improvement; patient satisfaction; disability and influence of psychosocial factors, strength of the lower limbs and the mobility of the posterior chain. Patients will be evaluated before and after the session and 1 week after. Trial registration number: RBR-2k58f5h Brazilian Registry of Clinical Trials (ReBEC).

Lay abstract Aim : Low back pain is one of the main health problems in the world. Short-wave diathermy (SWD) is a physiotherapy device that can be used to treat low back pain, but its scientific effectiveness is uncertain. Objective: To evaluate and compare the effects of pain reduction immediately after application of the device (SWD) in two different application methods in individuals with chronic low back pain. Materials & methods: Clinical trial in which 159 individuals will be selected and randomly allocated into three groups: pulsed short-wave diathermy group, n = 53; continuous short-wave diathermy group, n = 53 and placebo group, n = 53. The technique will only be applied once for 30 min. The main result analyzed will be pain. Other results that will also be evaluated are perception of global improvement and treatment satisfaction, functionality (ability to perform daily tasks), leg strength and trunk mobility. It will also be verified the presence of depression, anxiety, psychological and social factors that may influence the response to treatment. Individuals will be evaluated before the first session, immediately after the application of the device and 1 week later. Conclusion: It is expected to verify the decrease in pain soon after the application of the device in the chronic low back pain and find out if there is any difference in this outcome according to the application method.
