[Shortage of nurses in Spain: from the global case to particular situation. SESPAS Report 2024]. / Escasez de enfermeras en España: del caso global a la situación particular. Informe SESPAS 2024.

The nursing shortage is a multi-causal phenomenon that affects all countries and currently a global concern. The shortage of nurses jeopardizes the sustainability of health systems and the population health outcomes. Spain has historically had no difficulties in attracting new generations of nurses. The shortage of nurses is caused by the precarious working conditions and lack of professional development that have led to episodes of high international migration and abandonment of the profession. In this paper we focus on the evolution of different indicators of the working conditions of non-specialist nurses, who make up the bulk of the profession. These indicators allow us to analyse the abandonment of the profession, the duration of contracts, their full-time or part-time dedication and the excessive hiring. We have analysed the effect of COVID-19 and the labour reform on these indicators. COVID-19 reduced the abandonment of the profession and is currently at its lowest level, it has also accelerated the need to improve working conditions by increasing the percentage of permanent contracts and reducing the multiplicity of contracts in the same month. The labour reform has helped reduce the percentage of temporary contracts until reaching around 80% of the total contracts, and has reduced the number of nurses in Spain with more than one contract in the same month to below 3000 nurses on a sustained basis.

[Prevalence of burnout syndrome in physicians working in Spain: systematic review and meta-analysis]. / Prevalencia del síndrome de burnout en médicos que trabajan en España: revisión sistemática y metaanálisis.

OBJECTIVE: To analyze the prevalence of burnout syndrome in physicians working in Spain through a systematic review with meta-analysis METHOD: We searched PubMed/MEDLINE, Embase, and PsycINFO (up to June 2023). Observational studies conducted in Spain reporting the prevalence of burnout in physicians were included. From each study, methodological characteristics and results were extracted, and their quality was evaluated. We performed a narrative synthesis with random effects meta-analysis to calculate proportions. RESULTS: Sixty-seven studies with 16,076 participants were included. For the primary outcome, the meta-analysis revealed a global prevalence of burnout in physicians of 24% (95%CI: 19%-29%; 46 studies; 8821 participants; I2=97%). From subgroup analysis, differences were observed depending on the diagnostic criteria used: 18% (95%CI: 13%-23%) for three dimensions of burnout, 29% (95%CI: 24%-34%) for two dimensions and 51% (95%CI: 42%-60%) for one dimension. The heterogeneity between studies could not be fully explained through additional analyses where non-statistically significant differences were found with other variables (e.g., study quality, setting, professional category or medical specialty). CONCLUSIONS: A high prevalence of burnout syndrome was found in physicians working in Spain. These results can contribute to estimating the burden associated with burnout in physicians at a national level and to the design of future studies. Strategies appear to be necessary to prevent and mitigate this situation. PROTOCOL REGISTRATION: Open Science Framework: https://osf.io/b2h4m/.

Exposure to moral stressors and associated outcomes in healthcare workers: prevalence, correlates, and impact on job attrition.

Introduction: Healthcare workers (HCWs) often experience morally challenging situations in their workplaces that may contribute to job turnover and compromised well-being. This study aimed to characterize the nature and frequency of moral stressors experienced by HCWs during the COVID-19 pandemic, examine their influence on psychosocial-spiritual factors, and capture the impact of such factors and related moral stressors on HCWs' self-reported job attrition intentions.Methods: A sample of 1204 Canadian HCWs were included in the analysis through a web-based survey platform whereby work-related factors (e.g. years spent working as HCW, providing care to COVID-19 patients), moral distress (captured by MMD-HP), moral injury (captured by MIOS), mental health symptomatology, and job turnover due to moral distress were assessed.Results: Moral stressors with the highest reported frequency and distress ratings included patient care requirements that exceeded the capacity HCWs felt safe/comfortable managing, reported lack of resource availability, and belief that administration was not addressing issues that compromised patient care. Participants who considered leaving their jobs (44%; N = 517) demonstrated greater moral distress and injury scores. Logistic regression highlighted burnout (AOR = 1.59; p < .001), moral distress (AOR = 1.83; p < .001), and moral injury due to trust violation (AOR = 1.30; p = .022) as significant predictors of the intention to leave one's job.Conclusion: While it is impossible to fully eliminate moral stressors from healthcare, especially during exceptional and critical scenarios like a global pandemic, it is crucial to recognize the detrimental impacts on HCWs. This underscores the urgent need for additional research to identify protective factors that can mitigate the impact of these stressors.

This study explored the nature of moral stressors encountered by health care workers, along with impacts on moral injury and intentions to leave their jobs.Morally distressing encounters were common, with the most prevalent and distressing experiences being organizational or team-based in nature.Findings revealed that severity of moral injury, particularly related to trust violation or betrayal, was a key factor influencing healthcare workers' intentions to leave their jobs.

Síndrome de desgaste profesional en el personal de salud durante la pandemia de COVID-19 / Burnout Syndrome in Health Care Personnel During the COVID-19Pandemic

La Organización Mundial de la Salud (OMS) define el estrés laboral como una reacción que puede manifestarse ante exigencias y presiones laborales que ponen a prueba la capacidad que tiene cada persona para afrontar ciertas situaciones y que se agravan en el personal de salud que atiende pacientes con la COVID-19. Es decir, lo que resulta del desequilibrio entre las presiones y exigencias a las que se enfrenta el individuo, por una parte, y los conocimientos adquiridos por otra parte. El Síndrome de desgaste profesional, conocido también como síndrome de agotamiento emocional o psicológico, o por el anglicismo burnout, es un tipo de estrés laboral que engloba un estado de agotamiento físico, emocional y mental que conlleva a consecuencias individuales y sociales. El objetivo de esta revisión narrativa es identificar los factores de riesgo para el desarrollo del Síndrome de desgaste profesional en el personal de salud relacionado con la atención de pacientes con la COVID-19. Se realizó una búsqueda en la base de datos PubMed, se incluyeron artículos originales, estudios aleatorizados, revisiones sistemáticas y otros textos en español e inglés, publicados durante el periodo 2020-2023. Los principales factores de riesgo identificados en la literatura para el desarrollo de Síndrome de desgaste profesional fueron la juventud, sexo femenino, la soltería, la carga de trabajo y el nivel de satisfacción laboral de los profesionales.

The WHO defines occupational stress as a reaction that may occur when a person is faced with work-related demands and pressures that test the individual's ability to cope with certain situations, and it exacerbates in healthcare personnel who provide care to patients with COVID-19. That is, what results from the imbalance between the pressures and demands that the individual faces, on the one hand, and the knowledge acquired on the other hand. Burnout syndrome is a type of work-related stress that encompasses a state of physical, emotional and mental exhaustion that leads to individual and social consequences. The objective of this systematic review is to identify the risk factors for the development of Burnout Syndrome in health personnel related to the care of patients with COVID-19. A search was carried out in the PubMed database, including original articles, randomized studies, systematic reviews, and textbooks in Spanish and English, published during the period 2020-2023. The main risk factors for the development of Burnout Syndrome identified in the literature were youth, female sex, singleness, workload and the level of job satisfaction of the professionals

Factores psicosociales de riesgo y burnout en policías: un análisis de redes / Psychosocial risks factors and burnout in police officers: a network analysis

El estrés laboral crónico ha sido identificado como uno de los riesgos laborales más importantes que afecta a la salud mental de los agentes de policía. Existen ciertos factores psicosociales que incrementan el estrés laboral en la policía y que, a largo plazo, desencadenan síntomas compatibles con el burnout. En este trabajo se ha utilizado una muestra integrada por 323 policías para valorar la relación que se establece entre los factores psicosociales de riesgo y la probabilidad de experimentar síntomas compatibles con el burnout. Las respuestas de los participantes al MBI-GS y al F-PSICO (versión 4.0) fueron examinadas utilizando análisis de redes. Los resultados muestran que existen redes de factores psicosociales de riesgo más cohesionadas cuando los niveles de cinismo y agotamiento emocional son más elevados. Además, se observa mayor nivel de burnout asociados con una baja autonomía, altas demandas psicológicas, conflictos en el desempeño de rol y un bajo apoyo social percibido. Los resultados son discutidos en términos de su implicación teórica y de su utilidad práctica frente al diseño de entornos de trabajo más saludables, así como frente a la intervención psicológica.(AU)

Chronic work stress has been identified as one of the most important occupational hazards affecting the mental health of police officers. There are certain psychosocial factors that increase job stress in the police and, in the long term, trigger symptoms compatible with burnout. In this work, a sample made up of 323 police officers has been used to assess the relationship established between psychosocial risk factors and the probability of experiencing symptoms compatible with burnout. Participant responses to the MBI-GS and F-PSICO (version 4.0) were examined using network analysis. The results show that there are more cohesive networks of psychosocial risk factors when the levels of cynicism and emotional exhaustion are higher. In addition, a higher level of burnout is observed associated with low autonomy, high psychological demands, conflicts in role performance, and low perceived social support. The results are discussed in terms of their theoretical implication and their practical utility in the design of healthier work environments, as well as in psychological intervention.(AU)

Principais Dificuldades dos Cuidadores Informais da Pessoa com Doença Mental Grave / Main Difficulties of Informal Caregivers of People with Severe Mental Illness / Principales Dificultades de los Cuidadores Informales de la Persona con Enfermedad Mental Grave

Resumo Contexto: O processo de desinstitucionalização da pessoa com doença mental grave, trouxe uma nova realidade ao exigir uma adaptação das famílias, perante a necessidade dos seus membros assumirem o papel de cuidadores informais. Objetivo: Identificar as dificuldades dos cuidadores informais da pessoa com doença mental grave. Metodologia: Realizou-se um estudo descritivo transversal de base quantitativa. Foi constituída uma amostra probabilística aleatória simples de 27 cuidadores informais da pessoa adulta com doença mental grave, acompanhada na consulta externa de psiquiatria dum hospital da região Sul de Portugal. Como instrumento de colheita de dados foi aplicado o Índice de Avaliação das Dificuldades do Cuidador (CADI) e um questionário de caraterização sociodemográfica do cuidador informal. Resultados: Relativamente às características sociodemográficas dos participantes apurou-se que estas estão de acordo com o perfil que caracteriza os cuidadores informais em Portugal. Da aplicação do CADI, resulta que os fatores em que se verificaram mais dificuldades relacionadas com o cuidar foram os fatores relacionados com a falta de apoio familiar, com problemas financeiros, seguindo-se as reações à prestação de cuidados e a falta de apoio profissional. Conclusões: A função de cuidar causa dificuldades ao cuidador, que se vê perante um contexto diferente do habitual e a ter de desempenhar um novo papel. Assim, constatamos que os cuidadores familiares constituem um grupo com necessidades e dificuldades especificas, perante as quais o Enfermeiro Especialista Enfermagem Saúde Mental e Psiquiátrica tem um papel fundamental em termos de intervenção, na capacitação e empoderamento de quem cuida.

Abstract Context: The process of deinstitutionalization of the person with serious mental illness brought a new reality by requiring an adaptation of families, given the need for their members to assume the role of informal caregivers. Objective: To identify the difficulties of informal caregivers of people with severe mental illness. Methodology: A descriptive cross-sectional quantitative study was carried out. A simple random probabilistic sample of 27 informal caregivers of an adult person with severe mental illness was constituted, accompanied in the outpatient psychiatric clinic of a hospital in the south of Portugal. As a data collection instrument, the Caregiver's Difficulties Assessment Index (CADI) and a sociodemographic characterization questionnaire of the informal caregiver, were applied. Results: Regarding the sociodemographic characteristics of the participants, it was found that these are in line with the profile that characterizes informal caregivers in Portugal. From the application of the CADI, it appears that the factors in which there were more difficulties related to care were factors related to the lack of family support, financial problems, followed by reactions to the provision of care and the lack of professional support. Conclusions: The role of caring causes difficulties for the caregiver, who is faced with a different context than usual and having to play a new role. Thus, we found that family caregivers constitute a group with specific needs and difficulties, in view of which the Specialist Nurse Mental Health and Psychiatric Nursing has a fundamental role in terms of intervention, in the training and empowerment of those who care.

Calidad de vida profesional de quienes laboran en cuidados paliativos y su relación con el autocuidado, la atención plena y el sentido de vida / Professional quality of life of palliative care staff and its relationship with selfcare, mindfulness and meaning of life

Introducción: La calidad de vida profesional (que incluye satisfacción y fatiga por compasión) y sus factores asociados, han sido poco explorados en cuidados paliativos (CP) en Latinoamérica. Objetivo: Determinar la calidad de vida profesional en CP y su relación con el autocuidado, la capacidad de atención plena y el sentido de vida. Método: Estudio observacional, de corte transversal. Participaron profesionales laborando en CP en Colombia. Se empleó el PROQOL para evaluar satisfacción por compasión (SC), Burnout y trauma secundario (TS), el PSCS para examinar autocuidado, el MAAS para examinar atención plena y la Escala dimensional de sentido de vida (EDSV). Se realizaron análisis descriptivos, correlacionales y de regresión múltiple. Resultados: participaron 108 profesionales. Edad promedio 38 años, 55% médicos, 73% mujeres, 32,4% reportaron elevada afectación del bienestar por la Covid-19. El 85% obtuvieron puntuaciones medias o altas en SC, el 75,9% en Burnout y el 81,5% en TS (con medianas de 42.5, 21 y 12, respectivamente). Hubo una correlación positiva y significativa entre PSCS, MAAS y EDSV con SC, pero negativa y significativa con Burnout y TS. En conjunto, la SC, el MAAS y el autocuidado social tuvieron un efecto predictivo negativo sobre los niveles de Burnout (R2=0,535). Conclusiones: Aunque la mayoría de participantes están satisfechos con su labor, los índices de Burnout y TS fueron elevados durante el período de pandemia. El en conjunto, la satisfacción por compasión, la atención plena y el autocuidado social predijeron niveles menores de Burnout, indicando potenciales vías de apoyo para quienes ejercen CP (AU)

Introduction. Professional quality of life (involving compassion satisfaction and compassion fatigue) and its related factors have been poorly explored in Palliative Care (PC). Objectives. To determine the professional quality of life of PC practitioners in Colombia and its relationship with self-care, mindfulness and meaning of life. Methods. Observational cross-sectional study. Practicing professionals of PC of Colombia were invited. Compassion Satisfaction (CS), Burnout, and Secondary Trauma (ST) were assessed using PROQOL; selfcare was examined using PSCS; MAAS was used to assess Mindfulness capacity, and the Dimensional Scale of sense of life (EDSV) was also employed. Descriptive correlational, and multiple regression analyses were performed. Results. One-hundred and eight participants participated; mean age of 38 years, 73% women, 32,4% indicated high impact on their wellbeing due to Covid-19; 85% of participants showed medium-high scores on CS, 75,9% on Burnout, and 81,5% on ST (median scores of 42.5, 21, and 12, respectively). Scores on PSCS, MAAS and EDSV positively and significantly correlated with CS, and were negatively and significantly related with Burnout and ST. Altogether, SC, MAAS and social selfcare had a negative predictive effect on Burnout levels (R2=0.538). Conclusion. Although most participants were satisfied with their jobs, scores on Burnout, and TS were high during the Pandemic. Together, compassion satisfaction, mindfulness and social selfcare were predictive of lower levels of Burnout, signaling potential lines of intervention for PC practitioners (AU)

Rendimiento Clínico de las Restauraciones Adhesivas con Resina Compuesta en Casos de Pacientes con Desgaste Severo e Incremento de Dimensión Vertical: Revisión de Literatura Sistematizada / Clínical Performance of Adhesive Restorations with Composite Resin in Cases of Patients with Severe Wear and Increased Vertical Dimension: Systematized Literature Review

El desgaste dental severo se describe como la pérdida sustancial de la estructura dental, con exposición de la dentina y pérdida significativa de igual o más de 1/3 de la corona clínica. El uso de materiales compuestos de resina permite al clínico ser más conservador, debido a su aplicación mínimamente invasiva. Además de ello, son relativamente económicas, proporcionan buena estética general, así como un buen rendimiento y facilidad en la reparación. El objetivo de esta revisión de literatura sistematizada es recopilar información disponible en la literatura referente a cuál es el rendimiento clínico de las restauraciones adhesivas con resina compuesta en casos de pacientes con desgaste severo e incremento de la dimensión vertical como objetivo rehabilitador. Se analizaron artículos entre los años 2000 y 2022, seleccionando cuatro bases de datos (Pubmed, Scopus, Scielo y Web of Science). Para identificar los descriptores se utilizó los Medical subject headings (Mesh): Tooth Wear, Composite Restorations, Resin y Oral Rehabilitation. No se aplicó restricciones de idioma, país de origen, autor o lugar de publicación donde se realizó el estudio. Como resultado de la búsqueda se obtuvieron 71 artículos, de los cuales se seleccionaron 5 que cumplieron con los criterios de elegibilidad para ser considerados en la revisión de literatura sistematizada. Se encontró un promedio de tasa de éxito ente el 89,4 % - 100 % en un promedio total de 5.2 años de seguimiento. Se puede concluir, hasta donde se tiene conocimiento en la literatura científica disponible, que el tratamiento de restauraciones adhesivas con resinas compuestas en pacientes con desgaste severo es recomendable, enfocado en un periodo a corto-mediano plazo (3-5 años), siendo una opción de tratamiento económica y mínimamente invasiva.

Severe tooth wear is described as the substantial loss of tooth structure, with dentin exposure and significant loss of equal to or more than 1/3 of the clinical crown. The use of resin composite materials allows the clinician to be more conservative, due to its minimally invasive application. In addition to this, they are relatively inexpensive, provide good general aesthetics, as well as good performance and ease of repair. The objective of this systematic literature review is to collect information available in the literature regarding the clinical performance of adhesive restorations with composite resin in cases of patients with severe wear and increase in the vertical dimension as a rehabilitation objective. Articles between the years 2000 and 2022 were analyzed, selecting four databases (Pubmed, Scopus, Scielo and Web of Science). To identify the descriptors, the Medical subject headings (Mesh) were used: Tooth Wear, Composite Restorations, Resin and Oral Rehabilitation. No language, country of origin, author or place of publication restrictions where the study was conducted were applied. As a result of the search, 71 articles were obtained, of which 5 were selected that met the eligibility criteria to be considered in the systematic literature review. An average success rate between 89.4 % - 100 % was found in a total average of 5.2 years of follow-up. It can be concluded, to the best of our knowledge in the available scientific literature, that the treatment of adhesive restorations with composite resins in patients with severe wear is recommendable, focused on a short-medium term period (3-5 years), being a Inexpensive and minimally invasive treatment option.

Prevalencia del síndrome de desgaste en radiólogos españoles / Prevalence of burnout syndrome in Spanish radiologists

Objetivos: Analizar la prevalencia y grado del síndrome de desgaste profesional entre radiólogos en España. Como objetivos secundarios se pretende identificar sus posibles factores desencadenantes y atenuantes para implementar intervenciones preventivas y correctivas, disminuyendo el estrés asociado y aumentando el rendimiento y la satisfacción laboral de los radiólogos. Material y métodos: Estudio transversal y observacional realizado mediante una encuesta en línea, anónima y voluntaria, desarrollada a través de formularios de Google® y dirigida a radiólogos especialistas y en formación. La encuesta se estructura en tres apartados: una valoración cualitativa del grado del síndrome de desgaste profesional a través del Maslach Burnout Inventory Human Services Survey (MBI-HSS), el segundo constituido por una serie de preguntas sociodemográficas y laborales, y el último apartado centrado en las posibles causas de estrés y de mejora en el entorno laboral. Los resultados de la encuesta se analizaron estadísticamente para determinar la asociación entre las variables y el síndrome, así como para determinar posibles factores de riesgo y protectores.Resultados: Tras difundir la encuesta en redes sociales y correo electrónico se recibieron un total de 226 respuestas (175 de especialistas y 51 de residentes). La media de edad fue 41 años (desviación estándar de 11 años, rango de 25 a 68), sin predominancia de género (52% hombres). La prevalencia del síndrome fue del 33%, sin diferencias significativas entre adjuntos y residentes. No se han identificado factores de riesgo que se asocien con el desgaste profesional. Tener docencia en el lugar de trabajo fue el único factor de protección.(AU)

Background and aimsThe primary objective was to analyze the prevalence and degree of professional burnout in radiologists in Spain. Secondary objectives were to identify possible factors that increase or decrease the risk of burnout to enable preventive and corrective measures, decrease the stress associated with this condition, and thereby increase radiologists’ performance and satisfaction at work.Material and methodsThis cross-sectional observational study used a voluntary, anonymous online survey of attending radiologists and residents through Google Forms®. The survey was structured into three sections: a qualitative assessment of the degree of professional burnout with the Maslach Burnout Inventory Human Services Survey (MBI-HSS), a series of sociodemographic and work-related questions, and a final section centered on possible causes of stress and improvements to the working environment.The results of the survey were analyzed statistically to determine which variables were associated with burnout syndrome as well as to identify possible risk factors and protective factors.ResultsAfter disseminating the survey through social networks and email contacts, we received a total of 226 responses (175 from attending radiologists and 51 from residents; 52% men; mean age, 41±11 years; age range, 25-68). The prevalence of the syndrome was 33%, without significant differences between attending radiologists and residents. No risk factors associated with burnout were identified. Teaching in the workplace was the only protective factor.ConclusionsOne-third of the respondents had burnout syndrome. Because the consequences of this syndrome can affect professionals’ personal life and their ability to do their jobs, early detection and intervention should be prioritized.(AU)

Lesiones cervicales no cariosas: una revisión sistemática / Non carious cervical lesions: a systematic review

Introducción: las lesiones cervicales no cariosas (NCCL, por sus siglas en inglés) son un grupo de lesiones que afectan el área cervical del órgano dental causando hipersensibilidad dentinaria y defectos estéticos. Objetivo: analizar la literatura sobre las lesiones cervicales no cariosas, su etiología, consideraciones anatómicas, características morfológicas de la lesión y tratamientos no restaurativos. Material y métodos: se realizó una búsqueda en la base de datos PubMed, utilizando las palabras clave: non-carious cervical lesions OR noncarious cervical lesions OR tooth wear OR tooth erosion OR dental abfraction OR abfraction, recopilando un total de 78 artículos. Resultados: es necesario determinar la etiología antes de seleccionar las estrategias de tratamiento para las lesiones cervicales no cariosas. Conocer los distintos tipos de tejidos que componen al órgano dentario facilita la comprensión de los factores que participan en el desarrollo de las lesiones cervicales no cariosas. Esto permite que el tratamiento se enfoque más en la causa del problema que en los síntomas. Con esto podemos modificar diversos factores de manera interceptiva, los tratamientos de terapia con láser y compuestos tópicos son una estrategia mínimamente invasiva. Conclusiones: la mejor manera de describir a las lesiones cervicales no cariosas sería como una enfermedad multifactorial. Se debe prestar especial atención en los métodos de diagnóstico, identificando cofactores que propicien el avance de la lesión, como son la fricción y la biocorrosión. Esta revisión brinda datos que asocian a los factores oclusales como una de las principales causas de una enfermedad que afecta a más de la mitad de la población adulta (AU)

Introduction: non-carious cervical lesions (NCCL) are a group of lesions that affect the cervical area of the dental organ causing dentin hypersensitivity and cosmetic defects. Objective: to know, through a systematic review, the current state of non-carious cervical lesions. Material and methods: a search was conducted in the PubMed database, using the keywords: non-carious cervical lesions OR noncarious cervical lesions OR tooth wear OR tooth erosion OR dental abfraction OR abfraction, compiling a total of 78 articles. Results: determining etiology is necessary before selecting treatment strategies for non-carious cervical lesions (NCCL). Know the different types of tissues that make up the dentary organ, facilitate the understanding of the factors involved in the development of noncarious al cervical lesions. This allows treatment to focus more on the cause of the problem than on symptoms. With this we can modify various factors in an interceptive way, laser therapy treatments and topical compounds, are a minimally invasive strategy. Conclusions: the best way to describe non-carious al cervical lesions would be as a multifactorial disease to which special attention should be paid to both diagnostic methods, identifying cofactors that promote the progression of injury, such as friction and biocorrosion. This review provides data that associates occlusal factors as one of the main causes of a disease that affects more than half of the adult population (AU)

The prevalence of the syndrome was 33%, without significant differences between attending radiologists and residents. No risk factors associated with burnout were identified. Teaching in the workplace was the only protective factor. CONCLUSIONS: One-third of the respondents had burnout syndrome. Because the consequences of this syndrome can affect professionals' personal life and their ability to do their jobs, early detection and intervention should be prioritized.

Efectividad de una intervención breve en la resiliencia, atención plena y empatía de profesionales de enfermería / Effectiveness of a brief intervention on the resilience, mindfulness and empathy of nursing professionals

Objetivos: Evaluar la eficacia de una intervención guiada basada en la reducción del estrés y compasión, sobre la resiliencia, desgaste por empatía y atención plena de profesionales sanitarios. Metodología: Estudio cuasiexperimental con grupo control e intervención combinada multimodal impartido en 3 sesiones. Grupo control (n = 23), grupo experimental (n = 23). Recogida de datos: se hicieron 4 observaciones y se utilizaron las herramientas Escala Breve de Resiliencia, Inventario Friburgo de Mindfulness, Inventario de Desgaste por Empatía y datos sobre el perfil laboral y vida personal de las profesionales. Para analizar la relación entre variables se utilizó un modelo lineal general, la pruebas de chi cuadrado o de Fisher y análisis de regresión. Resultados: No se encontró un efecto significativo de la intervención evaluada en la puntuación obtenida en atención plena, resiliencia o empatía. El grupo control obtuvo mayor puntuación en atención plena cuando se relacionó con la unidad de trabajo no covid y la ausencia de estresores personales F (1,21)=16,081 p=<0,01, ŋ2=0,434. El perfil empático normal sin riesgo, fue significativamente mayor en unidades no covid frente a las covid en la primera evaluación (70% vs 30%, p=0,002). El perfil de baja resiliencia en técnicos de cuidados auxiliares de enfermería, fue mayor durante la última evaluación (72,2% vs 27,8%, p=0,003), momento que coincidió con un mayor número de pacientes hospitalizados por covid. Conclusiones: Factores personales y laborales (categoría profesional, la unidad de trabajo y presión asistencial) tuvieron más influencia en el bienestar psicológico de los profesionales, que la intervención realizada. (AU)

Objectives: Assess the efficacy of a guided intervention based on stress reduction and compassion, related to resilience and compassion fatigue of healthcare professionals. Methods: Quasi-experimental study with a control and intervention groups, combining a multimodal intervention delivered in 3 sessions. Control group (n = 23), experimental group (n = 23). Data collection: 4 observations were made using the Brief Resilience Scale, Freiburg Mindfulness Inventory, Compassion Fatigue Inventory and data on the professional profile and personal life. In order to analyze the relationship between variables, a general linear model, the chi-square or Fisher test, and regression analysis were used. Results: No significant effect of the evaluated intervention was found on the score obtained in mindfulness, resilience or empathy. The control group obtained a higher score in mindfulness when related to the non-covid work unit and the absence of personal stressors F(1.21)=16.081 p=<0.01, ŋ2=0.434. The normal empathic profile without risk was significantly higher in non-covid units compared to covid units in the first evaluation (70% vs 30%, p=0.002). The profile of low resilience in auxiliary nurses was higher during the last evaluation (72.2% vs 27.8%, p=0.003), a moment in which a greater number of patients were hospitalized with covid. Conclusions: A higher influences on professionals psychological wellbeing was present with personal and job related factors (professional category, work place and healthcare pressure) than the intervention carried out.

Cargas de trabalho de profissionais técnico-administrativos de uma instituição pública de ensino superior / Workloads of technical-administrative professionals at a public institution of higher education

Resumo: A saúde do trabalhador tem se deparado com novos desafios advindos, por exemplo, da pandemia da covid-19 e da indústria 4.0, o que implica na inevitabilidade de refletir sobre as cargas de trabalho nesse contexto. A dissertação que se segue tem como objetivo analisar as cargas de trabalho presentes no processo laboral dos técnico-administrativos de uma instituição pública de ensino superior no contexto da pandemia da covid-19. Sugere-se também reconhecer as estratégias utilizadas para o enfrentamento dessas cargas no meio laboral. Trata-se de uma pesquisa do tipo exploratória e descritiva, de natureza qualitativa. O estudo se dá na região sul do Brasil. Para esse fim, propõe-se a criação e testagem de um instrumento para identificar as cargas de trabalho que podem causar impactos negativos ou desgaste desses trabalhadores. Os pesquisadores Asa Laurell e Mariano Noriega (1989) orientam o referencial teórico do estudo, a partir do conceito de Cargas de Trabalho, classificadas em físicas, químicas, biológicas, mecânicas, fisiológicas e psíquicas. A coleta de dados se estabelece a partir da aplicação do instrumento criado, um questionário aplicado por meio de entrevista (presencial ou online), com 31 técnico-administrativos que exercem o cargo de secretário(a) nas coordenações de cursos de graduação de uma universidade pública federal. O tratamento dos dados se dá com base na Análise de Conteúdo Temática de Laurence Bardin (2016), com a proposição de duas categorias finais: a primeira sobre o reconhecimento das cargas de trabalho dos técnico-administrativos. Nessa categoria são apresentadas as cargas de trabalho que causam ou podem gerar algum tipo de desgaste nos trabalhadores. O percurso de investigação mostra que as cargas mais reconhecidas pelos trabalhadores pesquisados, a partir de sua percepção do processo de trabalho, são as psíquicas e fisiológicas, com atenção para as condições ergonômicas do trabalho. A segunda categoria, sobre as estratégias individuais e coletivas utilizadas por esses trabalhadores para o enfrentamento das cargas de trabalho, evidencia que os técnico-administrativos utilizam mecanismos individuais e coletivos como medidas protetivas contra os agravos decorrentes do labor, porém esses fatores de proteção requerem aprimoramento. Esses achados corroboram com o que traz a literatura sobre a presença dessas cargas nos ambientes de trabalho, principalmente nas áreas de prestação de serviços e atendimento a pessoas. Uma vez reconhecida a existência das cargas de trabalho, pode-se propor medidas de promoção à saúde e prevenção de doenças dos técnico-administrativos.

Abstract: Worker's health has faced new challenges arising, for example, the covid-19 pandemic and Health 4.0, which implies the inevitability of reflecting on workloads in this context. Therefore, the following dissertation aims to analyze the workloads present in the work process of administrative technicians at a public institution of higher education in the context of the covid-19 pandemic. It is also suggested to recognize the strategies used to face these workloads in the work environment. This is an exploratory and descriptive research, with a qualitative nature. The study takes place in the southern region of Brazil. This academic work proposes the creation and testing of an instrument (questionnaire) to identify the workloads that can cause negative impacts or cause wear on these Workers. Researchers Asa Laurell and Mariano Noriega (1989) guide the theoretical framework of the study, based on the concept of Workloads, classified as physical, chemical, biological, mechanical, physiological and psychological. For the data collection, the questionnaire was applied through interviews (in person or online), with 31 administrative technicians who work as secretary in the coordination of undergraduate courses at a federal public university. Data treatment is based on Laurence Bardin's Thematic Content Analysis (2016), with the proposition of two final categories: the first one is the recognition of administrative technical workers workloads. This category presents the workloads that cause or may generate some type of wear on workers. The investigation shows that the workloads most recognized by the surveyed, based on their perception of the work process, are psychic and physiological, with attention to the ergonomic conditions of work. The second category, about the individual and collective strategies used by these workers to handle with workloads, shows that the administrative technical workers use individual and collective mechanisms as protective measures against the damage resulting from work, but these protection factors require improvement. These findings corroborate with what the literature brings about the presence of these loads in work environments, especially in the areas of service provision and assistance to people. Once the existence of workloads is recognized, measures can be proposed to promote health and prevent diseases for these administrative technical workers.

The ability of different formulations of artificial saliva to protect dentin from erosive wear / Ação protetora de diferentes formulações de saliva artificial no desgaste erosivo

Objective: Evaluate the protective effect of artificial saliva formulations associated or not with mucin on dentin. Materials and Methods: Bovine dentin specimens were randomly allocated to 10 groups (n = 20) according to the artificial saliva tested and the presence or absence of mucin: Amaechi et al. (1998); Klimek et al. (1982); Vieira et al. (2005) and Eisenburger et al. (2001) and deionized water (control). Samples were submitted to an erosive cycle consisting of two immersions of 120 min in the saliva, followed by 1 min in hydrochloric acid solution, and new storage in saliva for 120 min. Surface loss (µm) was measured before and after the cycle. Data were analyzed using 2-way ANOVA and Tukey's test (p < 0.05). Results: A significant difference was observed for the saliva formulation but not for the presence of mucin. The deionized water provided the highest surface loss and the Eisenburger's saliva formulation the lowest. The groups testing the Amaechi, Klimek, and Vieira saliva did not present significant differences. Conclusion: Eisenburger's saliva formulation provides a higher protective effect against dentin erosion. The presence of mucin did not increase the erosion-preventive effect of artificial saliva formulations. (AU)

Objetivo: Avaliar o efeito protetor de formulações de saliva artificial associadas ou não à mucina sobre a dentina submetida a erosão. Material e Métodos: Espécimes de dentina bovina foram alocados em 10 grupos (n = 20) de acordo com a saliva testada e a presença ou ausência de mucina: . Amaechi et al. (1998); Klimek et al. (1982); Vieira e cols. (2005), Eisenburger et al (2001) e agua deionizada (controle). As amostras foram submetidas a um ciclo erosivo composto por duas imersões de 120 min na saliva, seguidas de 1 min em solução de ácido clorídrico e novo armazenamento na saliva por 120 min. A perda de superfície (µm) foi medida antes e depois do ciclo. Os dados foram analisados usando ANOVA 2 fatores e teste de Tukey (p <0,05). Resultados: Foi observada diferença significativa para a formulação de saliva, mas não para a presença de mucina. A água deionizada proporcionou a maior perda de superfície e a formulação de saliva de Eisenburger a menor. Os grupos que testaram a saliva Amaechi, Klimek e Vieira não apresentaram diferenças significativas entre si. Conclusão: A formulação de saliva de Eisenburger fornece o maior efeito protetor contra a erosão dentinária e a presença de mucina não aumentou o efeito preventivo de erosão de formulações de saliva artificial (AU).

Tooth wear due to dental attrition among 12-year-old adolescents / Desgaste dentário por atrição entre adolescentes de 12 anos de idade

Aim: To evaluate the prevalence and distribution of tooth wear due to dental attrition among 12-year-old adolescents according to their gender, reports of tooth grinding during sleep/while awake (bruxism), and sleep features related to sleep-disordered breathing. Methods: A cross-sectional study was conducted with 172 adolescents from southeast Brazil. Parents/caregivers answered questions about sociodemographic characteristics; reports of adolescents' tooth grinding during sleep, and sleep features (e.g. sleep duration and position, snoring, drooling on the pillow) in the previous two weeks. Adolescents self-reported the occurrence of tooth clenching/grinding while awake in the previous two weeks. Tooth wear due to dental attrition was assessed by a previously calibrated researcher, using a validated 5-point analogical ordinal occlusal/incisal tooth wear grading scale, with scores ranging from 0 (no wear) to 4 (loss of crown height ≥ 2/3), depending on tooth wear severity. Descriptive statistics and the Mann-Whitney test (p < 0.05) were performed to identify differences in tooth wear due to the distribution of dental attrition, according to adolescents' characteristics. Results: Most adolescents were female (58.0%) and 81.6% of the participants presented tooth wear due to dental attrition within the enamel. Adolescents who snored had a higher number of incisors with tooth wear due to dental attrition (p = 0.035). Females showed a higher number of canines with tooth wear due to dental attrition (p = 0.020). Adolescents whose parents reported tooth grinding during sleep presented a higher number of bicuspids with tooth wear due to dental attrition (p = 0.001). Conclusion:Tooth wear due to dental attrition within the enamel was observed in most adolescents. The distribution, depending on specific groups of teeth, was higher among female adolescents, adolescents' whose parents reported tooth grinding, and adolescents who snored during sleep.

Objetivos: Avaliar a prevalência e distribuição de DDA entre adolescentes de 12 anos de acordo com o sexo, relato de ranger de dentes durante o sono e vigília (bruxismo) e características relacionadas a desordens respiratórias do sono.Método: Desenvolveu-se um estudo transversal com 172 adolescentes do sudeste do Brasil. Seus pais/responsáveis responderam um questionário contendo informações sociodemográficas, relato sobre os filhos rangerem os dentes durante o sono e hábitos do sono dos filhos (duração do sono, posição que dorme, roncar, babar no travesseiro) nas duas últimas semanas. Adolescentes relataram ocorrência de ranger/apertar de dentes durante a vigília nas duas últimas semanas. DDA foi avaliado por um pesquisador previamente calibrado através de uma escala analógica ordinal de cinco pontos de desgaste dentário para faces oclusal/incisal previamente validada, com escores variando de 0 (sem desgaste) a 4 (perda da coroa em altura ≥ 2/3), dependendo da gravidade do desgaste. Análises descritivas e teste de Mann-Whitney (p < 0,05) foram realizados para identificar as diferenças na distribuição de DDA de acordo com as características dos adolescentes.Resultados: A maioria dos adolescentes eram meninas (58,0%) e 81,6% dos participantes apresentaram DDA em esmalte em algum elemento dentário. Adolescentes que rocavam apresentavam mais incisivos com DDA (p = 0.035). Meninas apresentaram maior número de caninos com DDA (p = 0.020). Adolescentes que rangiam os dentes durante a noite apresentaram maior número de pré-molares com DDA (p = 0.001).Conclusão: Desgaste dentário por atrição em esmalte foi observado na maioria dos adolescentes. A distribuição, dependendo de grupos de dentes específicos, foi maior entre meninas, adolescentes que roncavam durante o sono e que rangiam os dentes durante o sono.

Effect of 10% Proanthocyanidin gel on demineralized organic matrix degradation: ELISA method / Efeito do gel de Proantocianidina a 10% na degradação da matriz orgânica desmineralizada: método ELISA

Objective: This study evaluated Proanthocyanidin protective effect on dentin subjected to erosion and its inhibition on degradation of the demineralized organic matrix (DOM). Material and Methods: The tested groups were: G1 - 10% Proanthocyanidin gel (test group), G2 - 1.23% NaF (positive control 1), G3 - 0.012% Chlorhexidine (positive control 2) and G4 ­ Placebo (negative control with no active compound) and two methodologies were performed: contact profilometry and ICTP ELISA method. To quantify dentin wear, profilometry was performed. Data were submitted to Analysis of Variance followed by Fisher's LSD Test. To assess the collagen degradation, ICTP ELISA method was performed. Data were submitted to the Kruskal-Wallis followed by the Dunn ́s test. Simple linear regression and Pearson Correlation test were also performed (p<0.05). Results: The profilometry showed significantly lower wear of G1 when compared to other groups and G2, G3 and G4, which did not present significant difference among them. In the ICTP ELISA analysis, G1 and G4 did not show significant differences and the same happened between G2 and G3. However, G1 and G4 had lower values of collagen degradation compared to groups G2 and G3. Data showed that degraded DOM is a significant predictor to explain the values obtained through the ICTP ELISA. Conclusions: The results allow to verify that 10% proanthocyanidin provided less tooth wear and decreased degradation of the DOM, suggesting a good ability to prevent dentin erosion. The regression analysis also suggests that contact profilometry is a good strategy to quantify dentin wear (AU)

Objetivo: Este estudo avaliou o efeito protetor da proantocianidina na dentina submetida à erosão e sua inibição na degradação da matriz orgânica desmineralizada (MOD). Material e Métodos: Os grupos testados foram: G1 - gel de Proantocianidina 10% (grupo teste), G2 - NaF 1,23% (controle positivo 1), G3 - Clorexidina 0,012% (controle positivo 2) e G4 - Placebo (controle negativo sem princípio ativo) e duas metodologias foram realizadas: perfilometria de contato e método ICTP ELISA. Para quantificar o desgaste da dentina, a perfilometria foi realizada. Os dados foram submetidos à Análise de Variância seguida do Teste LSD de Fisher. Para avaliar a degradação do colágeno, foi realizado o método ICTP ELISA. Resultados: Os dados foram submetidos ao teste de Kruskal-Wallis seguido do teste de Dunn. Regressão linear simples e teste de correlação de Pearson também foram realizados (p<0,05). A perfilometria mostrou desgaste significativamente menor do G1 quando comparado aos outros grupos e G2, G3 e G4, que não apresentaram diferença significativa entre si. Na análise ICTP ELISA, G1 e G4 não apresentaram diferenças significativas e o mesmo ocorreu entre G2 e G3. No entanto, G1 e G4 apresentaram valores menores de degradação do colágeno em relação aos grupos G2 e G3. Os dados mostraram que a MOD degradada é um preditor significativo para explicar os valores obtidos pelo ICTP ELISA. Conclusão: Os resultados permitem verificar que a proantocianidina a 10% proporcionou menor desgaste dentário e diminuição da degradação da MOD, sugerindo uma boa capacidade de prevenir a erosão dentinária. Também sugere que a perfilometria de contato é uma boa estratégia para quantificar o desgaste da dentina (AU)

How does arch form and interproximal contact size affect the 3D displacements and rotations of teeth: a finite element analysis

ABSTRACT Objective: The objective of this study was to determine how arch form and interproximal contact size displace mandibular teeth subjected to an anterior component of force (ACF). Methods: Nine finite element models (FEM) of the mandibular arch were developed using Ansys® v. 16.0 software. They were designed to evaluate the effects of three arch forms (triangular, oval, and square) and three contact sizes (point-to-point, 1 mm diameter, and 2 mm diameter). All nine models were subjected to an ACF of 53.8 N (5486 gm). Three-dimensional tooth rotations and displacements of the mandibular teeth were evaluated, from the right first molar to the left first molar. Results: Arch form had a greater effect on tooth movements than contact size. Triangular arches and point-to-point contacts produced the greatest displacements and rotations of teeth. Oval arches with 2 mm wide interproximal contact points showed the greatest stability. The right first premolar showed the greatest displacements in all of the models. Conclusions: Arch form and contact size affect interproximal tooth stability. Teeth are least stable in narrow arches with point-to-point interproximal contacts, and most stable in wider arches with larger contacts.

RESUMO Objetivo: O objetivo deste estudo foi determinar como o formato da arcada e o tamanho do contato interproximal deslocam os dentes inferiores submetidos a um componente anterior de força (CAF). Métodos: Nove modelos de elementos finitos (MEF) da arcada inferior foram desenvolvidos utilizando o software Ansys® v. 16.0. Eles foram projetados para avaliar os efeitos de três formatos de arcada (triangular, oval e quadrado) e três tamanhos de contato interproximal (ponto a ponto, 1 mm de diâmetro e 2 mm de diâmetro). Todos os nove modelos foram submetidos a um CAF de 53,8 N (5486 gm). Foram avaliados tridimensionalmente as rotações dentárias e os deslocamentos dos dentes inferiores, do primeiro molar direito ao primeiro molar esquerdo. Resultados: A forma da arcada teve um efeito maior no movimento dos dentes do que o tamanho do contato interproximal. Arcadas triangulares e contatos ponto a ponto produziram os maiores deslocamentos e rotações dos dentes. Arcadas ovais com pontos de contato interproximal de 2 mm de largura apresentaram maior estabilidade. O primeiro pré-molar direito apresentou os maiores deslocamentos em todos os modelos. Conclusões: O formato da arcada e o tamanho do contato interproximal afetam a estabilidade dos dentes. Os dentes foram menos estáveis nas arcadas estreitas com contatos interproximais ponto a ponto, e mais estáveis nas arcadas mais largas com contatos maiores.
