Demandas e recursos para predição da síndrome de burnout em psicólogos clínicos / Demands and resources for burnout syndrome on clinical psychologists / Demandas y recursos para la predicción del síndrome de burnout en psicólogos clínicos

O modelo de demandas e recursos foi utilizado para identificar o poder preditivo do estilo pessoal do terapeuta e do trabalho emocional (demandas), e da inteligência emocional e autoeficácia profissional (recursos) sobre as dimensões da síndrome de Burnout (SB), em uma amostra de 240 psicólogos clínicos brasileiros. Os dados foram coletados por meio de plataforma online, tendo como instrumentos de pesquisa um Questionário de dados sociodemográficos e laborais, o Cuestionario para la Evaluación del Síndrome de Quemarse por el Trabajo, o Cuestionario del Estilo Personal del Terapeut, o Questionário de Avaliação Relacionado a Demandas Emocionais e Dissonância da Regra da Emoção, Medida de Inteligência Emocional, e Escala de Autoeficácia Geral Percebida. Os resultados obtidos revelaram um modelo preditor das dimensões da SB, constituído pelas variáveis dissonância emocional, automotivação, demandas emocionais, instrução, envolvimento e autoeficácia. Ressalta-se a relevância de estratégias voltadas para a prevenção da SB nessa categoria profissional, bem como a necessidade de ações que visem a promoção e o desenvolvimento da inteligência emocional e da autoeficácia como fortalecimento dos recursos emocionais para atuação na prática clínica.(AU)

The Model of Demands - Resources was used to identify the predictive power of therapist's personal style, emotional work (Demands), Emotional intelligence, and professional self-efficacy (Resources) over the Burnout syndrome dimensions in a sample of 240 Brazilian clinical psychologists. The data was collected by an on-line platform using a Labor and social demographic data questionnaire, a work Burnout Syndrome Evaluation questionnaire (CESQT - Cuestionario para la Evaluación del Síndrome de Quemarse por el Trabajo), the short version of the Therapist Personal Style Questionnaire (EPT-C Cuestionario del Estilo Personal del Terapeuta), an Evaluation questionnaire related to emotional demands and emotion rule dissonance, and the Emotional Intelligence Measure (EIM) and Perceived General Self-Efficacy Scale (GPSS) as research instruments. Results showed a predictor model of Burnout syndrome constituted by the variables Emotional dissonance, Self-motivation, Emotional demands, Instruction, Involvement, and Self-efficacy. We emphasize the relevance of strategies to prevent Burnout Syndrome in this professional category and the need for actions to promote and develop emotional intelligence and self-efficacy as a strengthening factor of the emotional resources to work as a clinical psychologist.(AU)

Estresse ocupacional entre psicólogos atuantes na atenção primária à saúde no contexto pandêmico / Occupational stress in psychologists working in primary health care in the context of the pandemic / Estrés laboral entre los psicólogos que trabajan en atención primaria de salud en el contexto de la pandemia

Este estudo analisa o estresse ocupacional entre psicólogos que atuavam na Atenção Primária à Saúde durante a pandemia ocasionada pela covid-19, assim como as características sociodemográficas e laborais dos participantes e sua relação com o estresse ocupacional. Participaram da pesquisa 70 psicólogos atuantes em 51 unidades básicas de saúde das regiões Oeste e Extremo Oeste catarinense. Para coleta de dados, um questionário sociodemográfico e a versão reduzida da Job Stress Scale (JSS) foram aplicados. A análise dos dados foi realizada por meio da estatística descritiva e inferencial. Identificou-se que 35,7% dos psicólogos apresentaram alto desgaste no trabalho; 28,6% baixo desgaste; 27,1% se mostraram em trabalho passivo; e 8,6% em trabalho ativo. No modelo de regressão linear, os fatores associados à dimensão Demanda da JSS foram: possuir filho (a) (coeficiente -1,49; IC 95% -2,75 a -0,23) e afastamento do trabalho nos últimos 12 meses (coeficiente 1,88; IC 95% 0,60 a 3,15). Os psicólogos com hipertensão arterial sistêmica autorreferida apresentaram, em média, 3,96 pontos a menos no escore de Apoio social (IC 95% -7,06 a -0,85), quando comparados aos não hipertensos, e entre os psicólogos que trabalhavam no turno da manhã identificou-se aumento de 4,46 pontos, em média, no escore de Apoio social (IC 95% 0,90 a 8,02) em relação aos profissionais do turno manhã e tarde. Evidenciou-se que um número significativo de psicólogos apresentava-se em alto desgaste no trabalho, com potenciais implicações para sua saúde e atuação profissional.(AU)

This study analyzed occupational stress among psychologists who worked in Primary Health Care during the COVID-19 pandemic and participants' sociodemographic and work characteristics and their relationship with occupational stress. In total, 70 psychologists working in 51 basic health units in the West and Far West regions of Santa Catarina participated in this research. A sociodemographic questionnaire and the short version of the Job Stress Scale (JSS) were applied to collect data. Data were analyzed by descriptive and inferential statistics. In total, 35.7% of psychologists showed high stress at work; 28.6%, low burn out; 27.1%, passive work; and 8.6%, active work. The factors in the linear regression model that were associated with the JSS demand dimension referred to having children (coefficient −1.49; 95% CI −2.75 to −0.23) and absence from work in the last 12 months (coefficient 1.88; 95% CI 0.60 to 3.15). Psychologists with self-reported systemic arterial hypertension showed, on average, 3.96 points lower in the Social Support score (95% CI −7.06 to −0.85) than non-hypertensive ones and psychologists who worked in the morning shift, an average increase of 4.46 points in the Social Support score (95% CI 0.90 to 8.02) in relation to professionals working in the morning and afternoon shifts. A significant number of psychologists had high stress at work, with potential implications to their health and professional performance.(AU)

Significados atribuídos por mulheres com câncer de mama ao grupo de apoio / Meanings attributed by women with breast cancer to a support group / Significados atribuidos por las mujeres con cáncer de mama al grupo de apoyo

A sobrevivência ao câncer de mama é um problema de saúde pública que demanda serviços especializados com foco na reabilitação psicossocial. Entre as necessidades identificadas nesse contexto está o incentivo à adoção de estratégias de promoção de autocuidados pelas mulheres. Uma das estratégias adotadas consiste no grupo de apoio psicológico, que auxilia as pacientes a enfrentar a longa jornada do tratamento. Assim, o objetivo deste estudo é compreender os significados produzidos por mulheres com câncer de mama sobre sua participação em um grupo de apoio. Trata-se de um estudo qualitativo, descritivo e exploratório realizado com dez mulheres com câncer de mama usuárias de um serviço de reabilitação para mastectomizadas. Como referencial metodológico foi utilizada a Teoria Fundamentada nos Dados. A coleta de dados foi realizada por meio de entrevista aberta em profundidade e os conteúdos foram transcritos e codificados. A análise indutiva e o método de comparação constante foram aplicados nos processos de codificação aberta, axial e seletiva, que permitiram identificar três categorias nucleares: percepção das atividades realizadas no grupo, identificação de benefícios e barreiras do convívio no grupo e transformações decorrentes da participação. As participantes significaram sua presença no grupo como fonte de acolhimento, apoio, desenvolvimento de recursos pessoais e amizades, contribuindo para promover sua qualidade de sobrevida. Além dos potenciais benefícios, também foram identificadas barreiras que podem dificultar a adesão e continuidade da participação no grupo, o que sugere a necessidade de incorporar no cuidado um olhar para as dimensões subjetivas da saúde da mulher.(AU)

Surviving breast cancer is a public health problem and depends on services focused on psychosocial rehabilitation. Healthcare providers must encourage women to adopt strategies to promote their self-care. The psychological support group is a resource that helps women to face the long journey of treatment. This study aimed to understand the meanings women with breast cancer produced about their participation in a support group. This exploratory cross-sectional study was carried out with 10 women with breast cancer who use a rehabilitation service for mastectomized patients. Grounded Theory was used as a methodological reference. An open in-depth interview was applied for data collection. The contents were transcribed and coded. Inductive analysis and the constant comparison method were applied in the open, axial, and selective coding processes, which enabled the identification of three core categories: perception of the activities carried out in the group, identification of benefits and barriers of living in the group, and transformations resulting from participation. Participants denote their involvement with the group as a source of shelter, support, development of personal resources and friendships that helps promoting quality of life. Besides these potential benefits, participants also evinced barriers that can hinder adherence and continuity of participation in the group, suggesting the importance of incorporating a look at the subjective dimensions of women's health into care.(AU)

Además de los beneficios potenciales, también se identificaron barreras que pueden dificultar la adherencia y continuidad de la participación en el grupo, lo que sugiere la necesidad de incorporar en la atención una mirada centrada en las dimensiones subjetivas de la salud de las mujeres.(AU)

Análise clínica da atividade de trabalho de agentes funerários no nordeste brasileiro / A clinical activity analysis of funeral agents' work in the brazilian northeast / Análisis clínico de la actividad laboral de agentes funerarios en el nordeste de Brasil

Especializados na gestão dos processos da morte e do morrer, os agentes funerários são uma categoria profissional indispensável na sociedade contemporânea. Estudar esses profissionais, marcados por alto grau de invisibilidade social, torna-se extremamente relevante, sobretudo concebendo-os como sujeitos ativos no processo de análise de sua atividade. Nesse sentido, este artigo teve como objetivo analisar a atividade de trabalho de agentes funerários a partir das contribuições teórico-metodológicas da Clínica da Atividade. Para o desenvolvimento desta pesquisa-intervenção foram realizadas 23 observações participantes no local de trabalho, 15 entrevistas individuais e seis entrevistas em grupo, mediadas pelo uso da técnica de Instruções ao Sósia, com agentes funerários que trabalham em um grande grupo funerário no interior do nordeste brasileiro. A análise da atividade de trabalho nos levou à compreensão de que o fazer desses trabalhadores é muito mais do que lidar meramente com o corpo inerte, sem vida, mas demanda deles alto grau de habilidades para lidar com suas emoções e prestar apoio às famílias enlutadas. O gênero profissional da atividade dos agentes funerários fornece importantes maneiras desses trabalhadores se portarem. Diante das imprevisibilidades e impedimentos presentes nas rotinas de trabalho, cada agente funerário age de um jeito, estiliza seu fazer, mas há aqueles modos de agir que são compartilhados, o que permite a construção do modo coletivo do agir profissional, tornando a atividade do agente funerário uma constante mescla do coletivo e do singular.(AU)

Specialized in the management of death processes, funeral agents are an indispensable professional category in contemporary society. It is extremely relevant to study these professionals who endure a high degree of social invisibility, especially by considering them as active subjects in the process of analyzing their own activities. Thus, this study aimed to analyze the work activity of funerary agents using the theoretical-methodological contributions of Clinical Activity. To develop this research-intervention, 23 participant-observations at their workplace, 15 individual interviews, and six group interviews, mediated by the use of the Instructions to the Double technique were carried out with funeral agents who work in a large funeral group in the inner Brazilian northeast. The analysis of work activity led us to understand that these workers' job prescriptions exceeds dealing with inert lifeless bodies. These workers have a high demand of socio-emotional skills, especially to cope and support grieving families. The professional genre in funeral agents' activity provide important ways for these workers to behave. As a result of the unpredictability and impediments in their work routines, funerary agents find their own way to meet the demands of work. However, their shared conducts enable them to construct the collective mode of professional action, making funerary agents' activity a constant mixture of collective and singular contributions.(AU)

En este sentido, este artículo tuvo como objetivo analizar la actividad laboral de agentes funerarios a partir de las contribuciones teórico-metodológicas de la Clínica de la Actividad. Para el desarrollo de esta investigación-intervención fueron realizadas 23 observaciones participantes en el local de trabajo, 15 encuestas individuales y seis grupales, mediadas por el uso de la técnica de instrucción al doble, con agentes funerarios que trabajan en un grupo funerario en el interior del Nordeste de Brasil. El análisis de la actividad laboral destaca que estos profesionales desempeñan una labor que va más allá del cuerpo inerte, sin vida, que les requiere un alto grado de habilidades para lidiar con las emociones y fornecer apoyo a las familias en duelo. El tipo profesional de la actividad de los agentes funerarios les proporciona a estos trabajadores importantes modos de portarse. Ante lo imprevisible y las dificultades en sus rutinas de trabajo, cada agente funerario actúa a su manera, pero hay modos de actuar compartidos, lo que permite la construcción del modo colectivo del actuar profesional, transformando la actividad del agente funerario en una constante mezcla entre lo colectivo y lo singular.(AU)

Análise do impacto econômico do absenteísmo em um hospital público durante a pandemia de COVID-19 / Analysis of the economic impact of absenteeism in a public hospital during the COVID-19 pandemic

Com a pandemia da COVID-19, uma grande quantidade dos profissionais da saúde adoeceu e se afastou do trabalho. Este estudo objetivou estimar o custo desses afastamentos em um hospital público brasileiro e ajudou a identificar as falhas nos processos de trabalho que levaram ao absenteísmo. É uma avaliação econômica parcial, descritiva, retrospectiva, quantitativa, com dados coletados de prontuários médicos, sobre os custos diretos dos afastamentos. A amostra foi de 793 servidores e 2.166 registros de atestados médicos, de março a dezembro de 2020. Observou-se que: o custo total dos afastamentos foi de R$ 2.603.017,95. As doenças virais representaram o maior custo, seguidas dos problemas relacionados à saúde mental. Os técnicos de enfermagem foram os profissionais que causaram o maior impacto nos afastamentos (27,21%). Portanto, a pesquisa gerou indicadores importantes para nortear os gestores na alocação de recursos e na tomada de decisões durante a pandemia da COVID-19.

With the COVID-19 pandemic, a large number of healthcare professionals became ill and were away from work. This study aimed to estimate the cost of these absences in a Brazilian public hospital and helped to identify the flaws in work processes that led to absenteeism. It is a partial, descriptive, retrospective, quantitative economic evaluation, with data collected from medical records, on the direct costs of sick leave. The sample consisted of 793 employees and 2.166 medical certificate records, from March to December 2020. It was observed that: the total cost of leaves was R$ 2.603.017,95. Viral diseases represented the highest cost, followed by problems related to mental health. Nursing technicians were the professionals who caused the greatest impact on sick leave (27.21%). Therefore, the research generated important indicators to guide managers in resource allocation and decision-making during the COVID-19 pandemic.

ANCA vasculitis and membranoproliferative glomerulonephritis associated with Sjögren's syndrome: Case report and literature review

ANCA-associated vasculitis may occur concomitantly with primary Sjögren's syndrome (SS) or arise during its evolution. We present the case of a patient who underwent dry symptoms, a positive Schirmer test and an SS-compatible autoimmunity profile and, simultaneously, deterioration of renal function, anaemia, and dyspnoea, requiring renal biopsy and fibro-bronchoscopy. Complementary studies documented acute necrotizing glomerulonephritis with extracapillary proliferation, and membranoproliferative pattern with immune complex deposition. Bronchoalveolar lavage was compatible with alveolar haemorrhage. Kidney lung syndrome secondary to ANCA vasculitis was diagnosed and treatment with steroid and intravenous cyclophosphamide with clinical and paraclinical improvement was instituted. Mixed renal involvement found in this case is uncommon in patients with SS, and treatment changes significantly, hence the importance of differential diagnosis and reporting in the literature.

La vasculitis asociada con anticuerpos anticitoplasma de neutrófilos-ANCA puede presentarse concomitantemente con síndrome de Sjögren primario o surgir durante su evolución. Se presenta el caso de una paciente que cursó con síntomas secos, test de Schirmer positivo, perfil de autoinmunidad compatible con síndrome de Sjögren y, de forma simultánea, deterioro de la función renal, anemia y disnea, por lo que requirió biopsia renal y fibrobroncoscopia. Los estudios complementarios documentaron glomerulonefritis aguda necrosante con proliferación extracapilar y patrón membranoproliferativo con depósito de complejos inmunes. El lavado broncoalveolar fue compatible con hemorragia alveolar. Se hizo diagnóstico de síndrome de pulmón-rinón secundario a vasculitis ANCA y se instauró tratamiento con esteroide y ciclofosfamida intravenosa, con mejoría clínica y paraclínica. El compromiso renal mixto encontrado en este caso es infrecuente en pacientes con SS, y el tratamiento cambia ostensiblemente, de ahí la importancia del diagnóstico diferencial y el reporte en la literatura.

Bone marrow fibrosis is a rare disorder that can be associated with autoimmune diseases such as systemic lupus erythematosus (SLE), and can be confused with the manifestations of that disease. The case is presented on a patient with autoimmune myelofibrosis in the context of SLE.

La fibrosis de la médula ósea es una enfermedad rara que se puede ver asociada con enfermedades autoinmunes como el lupus eritematoso sistémico (LES) y que puede llegar a ser confundida con las manifestaciones propias de la enfermedad. Se presenta el caso de una paciente con mielofibrosis autoinmune en el contexto de LES.

El volumen medioplaquetario: su importancia en la práctica clínica / Mean platelet volume: its importance in clinical practice

Las plaquetas son fragmentos citoplasmáticos anucleados derivados de los megacariocitos que presentan función central, tanto en procesos fisiológicos como la hemostasia, así como también en procesos patológicos como la inflamación, la ateroesclerosis. El tamaño de las plaquetas, medido como volumen medio de plaquetas, es un marcador de reactividad plaquetaria, que proporciona información importante sobre el curso y pronóstico de una variedad de afecciones inflamatorias. El estudio de este marcador se ha utilizado como pronóstico en enfermedades cardiovasculares, preeclampsia y en la púrpura trombocitopénica. El objetivo de este trabajo es revisar los conceptos actuales basados en la evidencia científica relacionados con el volumen plaquetario medio e insistir en su evaluación y significado en la práctica clínica cotidiana(AU)

Platelets are enucleated cytoplasmic fragments derived from megakaryocytes, which have a central function, both in physiological processes such as hemostasis, as well as in pathological processes such as inflammation, atherosclerosis. Platelet size, measured as mean volume of platelets, is a marker of platelet reactivity, providing important information on the course and prognosis of a variety of inflammatory conditions. The study of this marker has been used as a prognostic in cardiovascular diseases, preeclampsia and in thrombocytopenic purpura. The objective of this paper is to review the current concepts based on scientific evidence related to the mean platelet volume and to insist on its evaluation and meaning in daily clinical practice(AU)

Understanding tubulointerstitial injury and repair mechanisms paves the way for renal outcome improvement in lupus nephritis / Entender la lesión tubulointersticial y los mecanismos de reparación será la vía para mejorar los desenlaces renales en nefritis lúpica

ABSTRACT Despite improvements in patient survival and quality of life, long-term renal survival has not changed significantly in the recent decades and nephritis relapses affect over 50% of patients with lupus nephritis. Renal fibrosis affecting the tubulointerstitial compartment is a central determinant of the prognosis of any kidney disease. Notwithstanding this evidence, the current 2003 ISN/RPS classification still focuses on glomerular pathology and does not include a mandatory score with clear subcategories of the tubulointerstitial injury in the biopsy. The pathogenesis, and the morphological and molecular characteristics of this process in patients with lupus nephritis will be considered, together with a discussion about the concepts the clinician needs to efficiently address in this injury during daily practice and in future clinical trials. Both tubulointerstitial inflammation and fibrosis are strongly correlated with poor renal outcomes in lupus nephritis, regardless of the extent of glomerular damage. Therefore, it is essential to develop reliable and noninvasive approaches to predict which patients are most likely to develop CKD so that appropriate interventions can be adopted before ESRD is established. Currently, no ideal method for monitoring kidney fibrosis exists, since repeated renal biopsies are invasive. Promising methods for assessing and monitoring fibrosis non-invasively include imaging techniques, such as magnetic resonance imaging or ex vivo confocal microscopy, integrated in computational and digital pathology techniques. Finally, beyond specific immunosuppressive treatment in Lupus Nephritis, identifying and treating cardiovascular risk factors should be a cornerstone of treatment in these patients.

RESUMEN A pesar de las mejoras en la sobrevida de los pacientes y su calidad de vida, la sobrevida renal en el largo plazo no ha cambiado significativamente durante las últimas décadas, y las recidivas nefríticas afectan a más del 50% de los pacientes con nefritis lúpica. La fibrosis renal, que afecta el compartimiento tubulointersticial, es un factor determinante central en el pronóstico de todas las patologías renales. A pesar de la evidencia, la actual clasificación ISN/RPS del 2003 todavía se concentra en la patología glomerular y no incluye un score obligatorio con claras subcategorías de la lesión tubulointersticial en la biopsia. Se hablará de la patogenia y las características morfológicas y moleculares de este proceso en pacientes con nefritis lúpica, así como de los conceptos que el clínico necesita para abordar esta lesión de manera eficiente en su práctica cotidiana y en los estudios clínicos a futuro. Tanto la inflamación tubulointersticial como la fibrosis se relacionan fuertemente con desenlaces renales pobres en la nefritis lúpica, con independencia de la extensión del dañío glomerular. Resulta por lo tanto esencial desarrollar sistemas confiables y no invasivos para predecir cuáles pacientes tendrán mayor probabilidad de desarrollar enfermedad renal crónica, a fin de realizar las intervenciones apropiadas antes de que se establezca la enfermedad renal terminal (ERT). En la actualidad, no existe un método ideal para monitorear la fibrosis renal, dado que las biopsias repetidas son procedimientos invasivos. Algunos de los métodos promisorios para evaluar y monitorear la fibrosis de manera no invasiva son las técnicas de imágenes, tales como la resonancia magnética o la microscopía confocal ex vivo, integradas en técnicas de patología computarizadas y digitales. Finalmente, más allá del tratamiento inmunosupresor específico para la nefritis lúpica, identificar y tratar los factores de riesgo cardiovascular deberá ser uno de los pilares de tratamiento en estos pacientes.

Prevalencia de factores de riesgo en pacientes mayores de 50 años con fracturas clásicas de fragilidad atendidos en un hospital de tercer nivel de complejidad en Boyacá / Prevalence of risk factors in patients older than 50 years with classic fragility fractures treated in a third level complexity hospital in Boyacá (Colombia)

RESUMEN Introducción: Las fracturas por fragilidad son una complicación frecuente de la osteoporosis y generan alto impacto en la calidad de vida del adulto mayor. Las fracturas de cuello femoral, radio distal, húmero proximal y vértebras toracolumbares, en el contexto de un traumatismo menor, se consideran fracturas por fragilidad. Objetivo: Identificar la prevalencia de factores de riesgo en personas mayores de 50 arios con fracturas por fragilidad atendidas en un hospital del departamento de Boyacá. Metodología: Estudio observacional, descriptivo y de corte transversal. Se incluyeron 242 pacientes que presentaron fracturas por fragilidad con diagnóstico confirmado por estudio imagenológico. Resultados: El 62,8% de la población fue femenina. La edad condiciona un aumento del número de fracturas de fémur. El 10,7% de la población tenía un antecedente de fractura, con un aumento de la prevalencia a mayor edad. La fractura de radio distal fue la más frecuente en el 36,8% de la población. Cerca del 40% de los pacientes eran hipertensos y el 7,9% tenía diabetes, en tanto que el 9,7% eran consumidores crónicos de inhibidores de la bomba de protones. El 2,4% consumía glucocorticoides previamente al evento. Conclusiones: El comportamiento poblacional de las fracturas por fragilidad en nuestra ins titución es similar al de otros lugares, tanto a escala nacional como internacional. Por tanto, es importante empezar a crear conciencia sobre la prevención secundaria de la osteoporo sis, con el fin de disminuir las complicaciones, mejorar los desenlaces y disminuir los gastos que consigo trae.

ABSTRACT Introduction: Fragility fractures are a frequent complication of osteoporosis and lead to increased morbidity and mortality, as well as decreasing quality of life of the elderly popu lation, and represents high costs for health care systems. After minor trauma, fractures of the femoral neck, distal radius, proximal humerus, and thoraco-lumbar vertebrae are associated with osteoporosis, and are considered fragility fractures. Objective: To identify the prevalence of risk factors in people over 50 years of age with fragility fractures treated at a third level hospital in the department of Boyacá, Colombia. Methodology: Observational, descriptive, retrospective cross-sectional study. An evaluation was made on 242 patients between 50 and 100 years of age with any of the previously mentioned 4 fragility fractures. Fracture diagnosis had to be confirmed by plain radiography or computed tomography. Results: The majority (62.8%) of the study population was female. Age was associated with an increase in the number of femur fractures. A history of previous fractures was observed in 10.7% of the cases, with prevalence increasing with age. Distal radius fracture was the most frequent in 36.8% of the population. About 40% of the patients had hypertension and 7.9% were diabetic. Chronic use of proton pump inhibitors was observed in 9.7%, and 2.4% consumed glucocorticoids prior to the event. Conclusions: The behaviour of fragility fractures of the population in our institution is simi lar to that of other places, both nationally and internationally. It is therefore important to start raising awareness about secondary prevention of osteoporosis, in order to reduce complications, improve outcomes, and reduce associated costs.

Evaluation of serum microRNA-30e-5p expression in systemic lupus erythematosus and its association with clinical manifestations: A cross-sectional study / Evaluación de la expresión del microARN-30e-5p sérico en el lupus eritematoso sistémico y su asociación con las manifestaciones clínicas: un estudio transversal

ABSTRACT Background: MicroRNAs (miRNAs) are non-coding RNAs that regulate gene expression post-transcriptionally. Accumulating evidence indicates that the miR-30 family takes part in the development of multiple tissues and organs, and is a potential contributor to various dis eases, including autoimmune disorders such as systemic lupus erythematosus (SLE). The aim of this study was to evaluate the expression of miR-30e-5p, a member of the miR-30 fam ily, and investigate its potential relationship to clinical characteristics and possible disease activity in an Egyptian SLE cohort. Methods: Serum samples from 40 SLE patients and 37 age and gender matched healthy sub jects were tested for miR-30e-5p expression level using the Taqman quantitative reverse transcription-polymerase chain reaction. Analysis was performed using the 2 - AACT method. Results: The mean age of the patients was 28.7 ± 7.9 years, with a mean disease duration of 6.4 ±5.3 years. The median fold change in serum miR-30e-5p among our SLE cohort was significantly higher 1.748 (0.223-20.485) compared to the control group 0.877 (0.058-3.522) (P = 0.02). Receiver operating characteristic curve analysis revealed that miR-30e-5p expres sion level can discriminate SLE patients from controls at a cut-off value >1.06 with the area under the curve (AUC) = 0.676 (95% CI: 0.559-0.794, P = 0.02), with 64.3% sensitivity and 61.5% specificity. There was no correlation between any of the demographic features, clinical manifestations (apart from serositis, P = 0.013) or disease activity and miR-30e-5p levels. Conclusion: Our study demonstrated elevated miR-30e-5p expression levels in serum sam ples of SLE patients. Apart from serositis, it was not associated with any other disease characteristics.

RESUMEN Antecedentes: Los microARN (miRNA) son ARN no codificantes que regulan la expresión de los genes después de la transcripción. Las pruebas acumuladas indican que la familia de miR-30 participa en el desarrollo de múltiples tejidos y órganos, y es un posible contribuyente a diversas enfermedades, incluidos los trastornos autoinmunes como el lupus eritematoso sistémico (LES). El objetivo de este estudio fue evaluar la expresión del miR-30e-5p, un miembro de la familia miR-30, e investigar su posible relación con las características clínicas y la posible actividad de la enfermedad en una cohorte egipcia de LES. Métodos: Se analizaron muestras de suero de 40 pacientes con LES y 37 sujetos sanos de edad y sexo similares para determinar el nivel de expresión de miR-30e-5p, utilizando la reacción en cadena de la polimerasa de transcripción inversa cuantitativa Taqman. El análisis se llevó a cabo empleando el método 2-AACT. Los resultados: La edad media de los pacientes fue de 28,7 ± 7,9 años, mientras que la duración media de la enfermedad fue de 6,4 ± 5,3 años. La mediana del cambio de pliegue del suero miR-30e-5p entre nuestra cohorte de LES fue significativamente mayor, 1,748 (0,223-20,485), en comparación con el grupo de control, 0,877 (0,058-3,522) (p = 0,02).

Endoscopic Ultrasound in the Diagnosis of Pancreatoduodenal Groove Pathology: Report of Three Cases and Brief Review of the Literature

The pancreatoduodenal groove is a small area where pathologic processes involving the distal bile duct, duodenum, pancreatic head, ampulla of Vater, and retroperitoneum converge. Despite great advances in imaging techniques, a definitive preoperative diagnosis is challenging because of the complex anatomy of this area. Therefore, surgical intervention is frequently required because of the inability to completely exclude malignancy. We report 3 cases of patients with different groove pathologies but similar clinical and imaging presentation, and show the essential role of endoscopic ultrasound (EUS) in making a specific preoperative diagnosis, excluding malignancy in the first case, changing diagnosis in the second case, and confirming malignancy in the third case. EUS was a fundamental tool in this cohort of patients, not only because of its ability to provide superior visualization of a difficult anatomical region, but because of the ability to guide precise, real-time procedures, such as fine-needle aspiration.

Metformin, an Activator of AMPK, Promotes the Growth of Hair Follicles via the AMPK/β-catenin Signaling Pathway / 대한피부과학회지

BACKGROUND: AMP-activated protein kinase (AMPK) is a serine/threonine protein kinase that plays a pivotal role in the balance of cellular energy metabolism. Recent studies have reported that AMPK has numerous roles in physiological conditions, and dysregulation of AMPK induces pathological processes and diseases. However, the role of AMPK and its activators have not yet been studied in the context of hair growth regulation. OBJECTIVE: To investigate the effects of metformin on dermal papilla (DP) and outer root sheath (ORS) cells, as well as the role of the AMPK pathway in hair growth. METHODS: We evaluated whether metformin, a well-known AMPK activator, had any beneficial effects on hair growth. In addition, to evaluate the molecular and cellular mechanisms that were involved, protein levels of AMPK and β-catenin were analyzed. RESULTS: Metformin increased the cellular proliferation of human DP and ORS cells. Ki-67 expression was also significantly increased after metformin treatment in the ex vivo hair follicle organ culture. Furthermore, DP and ORS cells treated with metformin had a significant increase in AMPK phosphorylation, which in turn suppressed β-catenin degradation and enhanced its nuclear accumulation. CONCLUSION: We demonstrated that metformin promoted hair growth via the AMPK/β-catenin signaling pathway in vitro with DP and ORS cells. The hair-promoting effects of AMPK activators may potentially be used for the treatment of alopecia, and further investigation will be needed in the future.

Up-regulation of NHE8 by somatostatin ameliorates the diarrhea symptom in infectious colitis mice model

Na⁺/H⁺ exchangers (NHEs) have been shown to be involved in regulating cell volume and maintaining fluid and electrolyte homeostasis. Pooled evidences have suggested that loss of Na⁺/H⁺ exchanger isoform 8 (NHE8) impairs intestinal mucosa. Whether NHE8 participates in the pathology of infectious colitis is still unknown. Our previous study demonstrated that somatostatin (SST) could stimulate the expression of intestinal NHE8 so as to facilitate Na⁺ absorption under normal condition. This study further explored whether NHE8 participates in the pathological processes of infectious colitis and the effects of SST on intestinal NHE8 expression in the setting of infectious colitis. Our data showed that NHE8 expression was reduced in Citrobacter rodentium (CR) infected mice. Up-regulation of NHE8 improved diarrhea symptom and mucosal damage induced by CR. In vitro, a similar observation was also seen in Enteropathogenic E. coli (EPEC) infected Caco-2 cells. Seglitide, a SST receptor (SSTR) 2 agonist, partly reversed the inhibiting action of EPEC on NHE8 expression, but SSTR5 agonist (L-817,818) had no effect on the expression of NHE8. Moreover, SST blocked the phosphorylation of p38 in EPEC-infected Caco-2 cells. Taken together, these results suggest that enhancement of intestinal NHE8 expression by SST could ameliorate the symptoms of mice with infectious colitis.

The potential theragnostic (diagnostic+therapeutic) application of exosomes in diverse biomedical fields

Exosomes are membranous vesicles of 30-150 nm in diameter that are derived from the exocytosis of the intraluminal vesicles of many cell types including immune cells, stem cells, cardiovascular cells and tumor cells. Exosomes participate in intercellular communication by delivering their contents to recipient cells, with or without direct contact between cells, and thereby influence physiological and pathological processes. They are present in various body fluids and contain proteins, nucleic acids, lipids, and microRNAs that can be transported to surrounding cells. Theragnosis is a concept in next-generation medicine that simultaneously combines accurate diagnostics with therapeutic effects. Molecular components in exosomes have been found to be related to certain diseases and treatment responses, indicating that they may have applications in diagnosis via molecular imaging and biomarker detection. In addition, recent studies have reported that exosomes have immunotherapeutic applications or can act as a drug delivery system for targeted therapies with drugs and biomolecules. In this review, we describe the formation, structure, and physiological roles of exosomes. We also discuss their roles in the pathogenesis and progression of diseases including neurodegenerative diseases, cardiovascular diseases, and cancer. The potential applications of exosomes for theragnostic purposes in various diseases are also discussed. This review summarizes the current knowledge about the physiological and pathological roles of exosomes as well as their diagnostic and therapeutic uses, including emerging exosome-based therapies that could not be applied until now.

Analysis of Revision Surgery of Microsurgical Lumbar Discectomy

STUDY DESIGN: A retrospective study. PURPOSE: Our objectives were to determine the association between the pathological changes of disc herniation and the interval between primary and revision surgeries and to investigate the frequency and site of the dural laceration in the primary and revision surgeries. OVERVIEW OF LITERATURE: Among 382 patients who underwent microsurgical lumbar discectomy, we investigated 29 who underwent revision surgery to analyze recurrent herniation pathologies and complications to determine the manner in which lumbar disc herniation can be more efficiently managed. METHODS: Of 29 patients, 22 had recurrent disc herniation at the same level and site. The pathological changes associated with compression factors were classified into the following two types depending on intraoperative findings: (1) true recurrence and (2) minor recurrence with peridural fibrosis (>4 mm thickness). The sites of dural laceration were examined using video footage and operative records. RESULTS: The pathological findings and days between the primary and revision surgeries showed no statistical difference (p=0.14). Analysis of multiple factors, revealed no significant difference between the primary and revision surgery groups with regard to hospital days (p=0.23), blood loss (p=0.99), and operative time (p=0.67). Dural lacerations obviously increased in the revision surgery group (1.3% vs. 16.7%, p < 0.01) and were mainly located near the herniated disc in the primary surgery group and near the root shoulder in the revision surgery group, where severe fibrosis and adhesion were confirmed. To avoid dural laceration during revision surgery, meticulous decompressive manipulation must be performed around the root sleeve. CONCLUSIONS: We recommend that meticulous epidural dissection around the scar formation must be performed during revision surgery to avoid complications.

The Relationship between the Number of Manic Episodes and Oxidative Stress Indicators in Bipolar Disorder

OBJECTIVE: Bipolar disorder (BD) is a chronic mood disorder characterized by recurrent episodes that has a lifetime prevalence of 0.4–5.5%. The neurochemical mechanism of BD is not fully understood. Oxidative stress in neurons causes lipid peroxidation in proteins associated with neuronal membranes and intracellular enzymes and it may lead to dysfunction in neurotransmitter reuptake and enzyme activities. These pathological processes are thought to occur in brain regions associated with affective functions and emotions in BD. The relationship between the number of manic episodes and total oxidant-antioxidant capacity was investigated in this study. METHODS: Eighty-two BD patients hospitalized due to manic symptoms and with no episodes of depression were enrolled in the study. Thirty of the 82 patients had had their first episode of mania, and the other 52 patients had had two or more manic episodes. The control group included 45 socio-demographically matched healthy individuals. Serum total antioxidant capacity (TAC) and total oxidant capacity (TOC) measurements of the participants were performed. The oxidative stress index (OSI) was calculated by TOC/TAC. RESULTS: There were no significant differences in OSI scores between BD patients with first-episode mania and BD patients with more than one manic episode. However, OSI scores in both groups were significantly higher than in the control group. TOC levels of BD patients with first-episode mania were found to be significantly higher than TOC levels of BD patients with more than one manic episode and healthy controls. There were no significant differences in TAC levels between BD patients with first-episode mania and BD patients with more than one manic episode. TAC levels in both groups were significantly higher than in the control group. CONCLUSION: Significant changes in oxidative stress indicators were observed in this study, confirming previous studies. Increased levels of oxidants were shown with increased disease severity rather than with the number of manic episodes. Systematic studies, including of each period of the disorder, are needed for using the findings indicating deterioration of oxidative parameters.

An Emerging Role for Circular RNAs in Osteoarthritis

Circular RNAs (circRNAs) are currently classed as non-coding RNAs that, unlike the better known canonical linear RNAs, form a covalently closed continuous loop without 5′ or 3′ polarities. With the development of high throughput sequencing technology, a large number of circRNAs have been discovered in many species. More importantly, growing evidence suggests that circRNAs are abundant, evolutionally conserved, and relatively stable in cells and tissues. Strikingly, recent studies have discovered that circRNAs can serve as microRNA sponges, interact with RNA-binding protein, and regulate gene transcription, as well as protein translation. Osteoarthritis (OA) is the most common chronic degenerative joint disease. CircRNAs are differentially expressed in OA cartilage. Moreover, some circRNAs are involved in multiple pathological processes during OA, mainly extracellular matrix degradation, inflammation, and apoptosis. In this review, we briefly delineate the biogenesis, characteristics, and biofunctions of circRNAs, and then, focus on the role of circRNAs in the occurrence and progression OA.
